1 E2fsprogs 1.43.7 (October 16, 2017)
2 ===================================
4 Fix the error handling code in debugfs, fuse2fs and tune2fs so errors
5 trying to replay the journal won't accidentally result in a seg fault
6 if reopening the file system after the journal replay fails for some
9 Fix resize2fs to avoid it from either failing or corrupting the file
10 system image in certain corner cases when doing an off-line resize.
12 Fix many spelling mistakes in various man pages, code comments, and
15 Fix e2fsck and debugfs so that maliciously corrupted file systems will
16 not cause buffer overflows. (Addresses Debian Bugs: #873757, #878104)
18 Update German translation. (Addresses Debian Bug: #833514)
20 Fixed various Debian Packaging Issues. (Addresses Debian Bugs:
21 #873812, #873813, #876551)
26 Test descritions have been shorted to fit in 80 columns.
28 Fix various tests to avoid leaving temp files in /tmp.
31 E2fsprogs 1.43.6 (August 29, 2017)
32 ==================================
34 Fix printing of quota inconsistency messages on 32-bit platforms in
35 e2fsck. Also fix a bug which cause project quota problems to be
36 labelled as group quota problems.
38 Fix UI problems caused by fuzzy translations such that some messages
39 are in English and some are in the foreign language, and it's not
40 obvious to user how to answer yes/no questions. (Addresses Debian
43 Fix some out-of-bounds memory accesses in e2fsck caused by (usually
44 maliciously) corrupted file systems. (Addresses Debian Bugs: #871539,
47 Optimize CPU usage in e2fsck for very large, very fragmented sparse
50 Add an optional mode in e2fsck which trades off additional memory for
51 CPU time when processing file systems that are heavily hard-linked.
52 (This can be a very large amount of memory, so this feature is
53 disabled for now. How to automatically determine when it would be
54 helpful to enable this optimization, and when it is _safe_ to enable
55 this optimization is still a bit of a research problem.)
57 The mke2fs program will automatically upsize the inode size to 256 if
58 it is not explicitly specified on command-line and the default inode
59 size is not large enough to support the project quota feature
60 requested by the user. If the inode size is explicitly specified to
61 be 128 bytes, and the project quota is enabled mke2fs will fail since
62 with an error explaining that project id's can't be supported when the
63 inode size is < 256 bytes.
65 The tune2fs program will not allow the project feature or project
66 quotas to be enabled in the inode size is 128 bytes.
68 The tune2fs program now prints a more understandable message explaining
69 that the file system needs to be checked using e2fsck -f before
70 running certain complex tune2fs operations. (Addresses Debian Bug:
73 If the proceed_delay option is enabled in /etc/e2fsck.conf, the message
74 indicating that user can wait N seconds to proceed was ambiguous.
75 That message has been made more clear. (Addresses Debian Bug:
78 Fix LFS bug which caused e2image to fail to create regular e2image
79 files which are larger than 2 GiB on 32-bit platforms. (Addresses
82 Fix FreeBSD portability problem caused by the fact that they no longer
83 use block devices. (Disks are character mode devices.)
85 Update the Czech, French, Polish, Swedish, and Vietnamese translations.
87 Fixed various Debian Packaging Issues.
93 Avoid changing the blkid cache when running tests. (Normally the
94 blkid cache is not writable by the user running tests, but...)
96 The tar file generation process will now create reproducible
99 Removed legacy entries for ext4dev in the default mke2fs.conf file.
102 E2fsprogs 1.43.5 (August 4, 2017)
103 =================================
105 Fix a bug which could cause e2fsck to loop forever when rebuilding an
106 encrypted directory with entries with identical prefixes up to an
107 embedded NUL character.
109 Fix build when configured with --disable-threads or --enable-profile.
111 Fix ext2fs_sync_device() so it returns the proper error code if the
112 BLKFLSBUF ioctl fails for some reason.
114 Fix a potential crash in tune2fs when enabling project quota when the
115 file system has no inodes by fixing error handling in the
116 quota_write_inode() in libsupport.
118 Fix a bug in debugfs's "ls -p" handling which could cause it to print
119 garbage after a file name in a directory entry.
121 Fix a number of bugs in debugfs, dumpe2fs, e2fsck, tune2fs, and
122 resize2fs where a carefully/maliciously corrupted file systems (found
123 by American Fuzzy Lop) could these programs to crash or hang.
124 (Addresses Debian Bug #868489)
126 E2fsck no longer issues some harmless bitmap warnings caused by a
127 corrupted file system; since those corruptions will be fixed up by
128 e2fsck later, there's no point issuing these internal warnings.
130 E2fsck will now notice invalid quota inode numbers, and offer to fix
133 Fix a regression introduced in e2fsprogs 1.43 which broke mke2fs's
134 hugefile creation so that they aren't contiguous. (Addresses Google
135 Bugs 62791459 and 638037607)
137 Fix how backup superblocks are written in big endian systems so they
138 are all correctly byte swapped.
140 Fixed tune2fs's support for enabling and disabling project quota.
142 The badblock program now properly handles languages which have
143 multi-column wide character such as Chinese. (Addresses Debian Bug:
146 The mke2fs -U option now accepts "null", "clear", "random", or "time"
147 just as tune2fs's -U option.
149 Fix e2fsck's -E bmap2extent feature (which converts a file to use
150 extents from indirect block maps) so that it handles sparse files correctly.
152 Fix libext2fs to correctly handle accounting for an external xattr
153 block on bigalloc file systems.
155 Fix e2fsck to correctly handle quota accounting when deleting files
156 that have multiply-claimed blocks pass 1b.
158 Fix potential buffer overrun bug in e2fsck when using 128 byte inodes.
159 (Addresses Google Bug 37326362).
161 E2fsck's extent tree optimization can now be disabled via an
162 command-line extended option or via an e2fsck.conf configuration
165 The e2fsck program now properly updates the quota accounting when
166 optimizing the extent tree. (Addresses Google Bug 36391645)
168 Fix some error handling in e4crypt when operating on keyring ID's.
170 Fix e2fsck's quota handling when the bigalloc feature is enabled.
172 The libext2fs file system now uses readahead when opening file systems
173 to speed up opening very large file systems with the meta_bg option.
175 If e2fsck logging is enabled, e2fsck will report the exit code in the
176 last line of the log file.
178 Debugfs can now open file systems with a bad superblock checksum, and
179 the show_super_stats command will print the expected checksum.
181 Fix a regression introduced in e2fsprogs 1.43.4 where tune2fs was not
182 able to correctly enable the quota feature. (Addresses Debian Bug
185 E2fsck will only return an exit status code of 1 if it has fixed a
186 file system corruption. If it only performed an optimal optimization
187 of internal file system metadata, it will now return 0.
189 Fix e2fsck so it won't check inode fields of deleted inodes. This was
190 mostly harmless, but the addition of a check in 1.43.4 to enforce the
191 requirement that inline data inodes have a system.data attribute
192 caused a regression in xfstests generic/079. Fix this and a number of
193 other checks which could lead to false positive reports of file system
196 Removed a debugging printf in libsupport which could result to some
197 extraneous and confusing output if the user specifies a quota type.
199 The debugfs logdump command now accepts a new -S option which will
200 cause it to print information about the journal superblock.
202 Added a missing space in debugfs's ls -l output to separate the size
205 Update the Czech, Danish, Dutch, French, Hungarian, Polish, Serbian,
206 Spanish, Swedish, Ukrainian, and Vietnamese translations.
208 Update various man pages. (Addresses Debian Bugs #867895 and #865584)
210 Fix various compiler and UBSAN warnings.
212 Fixed various Debian Packaging Issues. (Addresses Debian Bugs
219 The blkid library can now recognize exfat file systems.
221 Add new test, j_recover_csum3_64bit, which checks to make sure we
222 correctly recovering 64-bit journals using the v3 checksum format.
224 Fix portability assumption in tests; don't depend on the existence of
227 Fix portability with newer versions of glibc and with Cygwin builds on
228 Windows 8 and Windows 10.
230 Clean up the comments in problem.c match the message that will
233 Removed an unused an obsolete header file.
237 E2fsprogs 1.43.4 (January 31, 2017)
238 ===================================
240 Fix e2fsck to require that the system.data extended attribute is
241 always present even for files smaller than 60 bytes, to be consistent
244 Fix a bug which was causing mke2fs -d and fuse2fs to improperly handle
247 Fix a bug which could cause mke2fs -d to fail if there is an
248 zero-length file in source directory tree.
250 Clarify the default for the "proceed?" question printed by mke2fs and
251 tune2fs. (Addresses Debian Bug: #852727)
253 Debugfs will now display project quota information.
255 Debugfs's do_set_xattr now uses C strings to parse extended attribute
256 values, and will print the extended attributes using either C strings
257 or hex bytes when using debugfs's do_get_xattr command. It will now
258 allow developers to see the contents of the system.data extended
261 Fix a bug in mke2fs where I/O errors weren't getting properly reported
264 Fix multiblock writes in the unaligned Direct I/O fallback code.
265 (Which is rarely needed on Linux systems, but which is required on
268 Make sure the default mke2fs.conf file includes the uninit_bg feature
269 flag. (Which was accidentally dropped in v1.43).
271 Fix a bug in resize2fs when operating on very large file systems which
272 have a block size different from the VM page size.
274 If the reported device size is absurdly large, mke2fs will now report
275 an error instead looping forever or crashing.
277 Fix various Coverity warnings and other memory leaks in fuse2fs and
278 extended attribute manipulation functions.
280 Replace a test file but which had a "non-commercial use-only"
281 copyright permission file with a newer version from the Cyrus imapd
282 package which now has a 4-clause BSD license, which was making some
283 lawyers nervous, even though the test file in question was only used
284 in lib/et's regression testing and was never included in any compiled
285 binary. (Addresses Debian Bug: #840733)
287 Stop installing mkfs.ext4dev and fsck.ext4dev
289 Update Chinese, Czech, Polish, Serbian, and Spanish translations and
290 add the Finnish and Malay translation. (Addresses-Debian-Bug: #774379)
292 Update various man pages (Addresses-Debian-Bug: #852726)
297 Fix more FreeBSD-11 compatibility bugs, including some unmasked by
302 Fix build failure on RHEL 5.x systems caused by an old version of
305 Fix a number of bugs reported by ASAN that can cause some (mostly
306 harmless) memory dereferences beyond allocated memory.
309 E2fsprogs 1.43.3 (September 4, 2016)
310 ====================================
312 Fix e2fsck's handling of timestamps on 32-bit systems.
314 E2fsck will now check, and if necessary repair the extra isize fields
315 in the inode and superblock.
317 Fix crashes on architectures such as sparc64 that are sensitive to
318 unaligned pointer dereferences in the journal recovery code when
319 journal checksums are enabled.
324 Support reproducible builds by not capturing the build directory into
325 the mk_cmds and compile_et scripts. Also fix debian build rules to
326 ensure build reproducibility.
328 Fix debian build rules to ensure build reproducibility and to avoid
329 hiding the linker flags for e2fsck.static so the build hardening log
330 scanner can properly audit the build.
332 Fix compatibility with FreeBSD's pmake and teach the configure script
333 to force the creation of pmake-compatible Makefiles if the
334 FORCE_NATIVE_MAKE environment variable is set to a non-empty value.
337 E2fsprogs 1.43.2 (September 1, 2016)
338 ====================================
340 Fix resize2fs so it will not crash if there is an extended attribute
341 block but it doesn't need to migrate any blocks during an off-line
344 Fix a crash when mke2fs or debugfs tries to copy in a directory
345 hierarchy containing an empty directory
347 Mke2fs will now use a larger journal by default for filesystems
348 greater than 128 GB. (1GB instead of 128 MB.)
350 Fix an alignment bug in e2fsck which caused sparc64 architectures to
351 crash when replaying the journal on file systems with a 64-bit block
354 Clarify the message printed by tune2fs message when the user needs to
355 run e2fsck so it's clear that the -f flag to e2fsck is needed to
356 force a full e2fsck scan. (Addresses Debian Bug: #828022)
358 Fix a bug in e2fsck caused by a power failure during e2fsck's journal
359 replay could leave the file system in a state where if the file system
360 is mounted without doing a full e2fsck scan, the file system could get
363 Fix the logic in e2fsck which decides when to repair legacy negative
366 Add a command to debugfs to copy the inode structure from one inode to
369 Fix a typo in debugfs's stat command when printing out the dtime field
370 on file systems with an extended timestamp.
372 Fix big endian bugs in the e2undo program. (Addresses Red Hat Bug
375 Debugfs's logdump can now properly handle journals larger than 2GB.
377 Avoid installing the man page for fuse2fs if it has not been built.
379 Update the Catalan, Chinese, Danish, Dutch, French, German, Polish,
380 Swedish, Ukrainian translations and added new translations for
381 Hungarian and Serbian.
387 Fix portability problems in fuse2fs. Previously it wouldn't build on
388 systems with older glibc versions where clock_gettime() is only
389 available in the librt library, and if libintl is not bundled into the
392 Remove complicated logic which caused a static code analyzer to flag a
393 false positive. (A static code analyzer also found a valid bug in
394 deciding when to repair a legacy negative timestamp encoding, so
395 eliminating false positives is important.)
397 Fixed a bug where the ext2fs library cloud provoke when a
398 extfs2_zero_blocks() is used (via fallocation, initializing a file
399 system, uninitialized uninitialized inode table blocks) after a
400 different file system which also used ext2fs_zero_blocks().
402 Enable the unix_io manager in the ext2fs library so it can accept the
403 use of a file descriptor. This is helpful in cases where the file
404 descriptor comes from temporary file created using O_TMPFILE, or
405 passed in from a unix domain socket.
407 Fix a Windows64 portability bug.
410 E2fsprogs 1.43.1 (June 8, 2016)
411 ===============================
413 Fixed e2fsck so that it would correctly update the project quota usage
414 when deleting a corrupted and inode, and fixed mke2fs so it wouldn't
415 dereference memory beyond the small inode structure (which was wrong,
416 but worked mostly by accident unless hardening or some security malloc
419 Fixed a large number of FreeBSD portability problems. (To build on
420 FreeBSD, however, we still need to use GNU Make and redirect dd to use
423 The configure script now supports --enable-hardening, which enables
424 stack protection, fortify, read-only relocation tables, immediate
425 dynamic symbol binding, and text segment ASLR (if the kernel has
426 userspace ASLR support enabled) by enabling position independent
427 executable code. (Distributions who want to do their own special
428 thing can set CFLAGS, CFLAGS_SHLIB, CLFAGS_STLIB, LDFLAGS,
429 LDFLAGS_SHLIB and LDFLAGS_STATIC as appropriate.)
431 The configure script now supports --disable-tdb since on 64-bit
432 systems, it's much faster to just enable additional swap space. The
433 scratch_files feature in e2fsck.conf is mostly only useful on 32-bit
436 Fixed the Direct I/O fallback codepath in the Unix I/O manager so that
437 read/modify/write worked correctly. Fortunately in practice (with the
438 exception of the Undo handler when running on FreeBSD) used this buggy
439 codepath. so file systems weren't getting corrupted.
441 Mke2fs will now warn if the user provides a label which is too long.
442 (Addresses Debian Bug: #791630)
444 Debugfs's rdump command now works correctly when dumping the root
445 directory of a file system. (Addresses Debian Bug: #766125)
447 Fixed a bug in debugfs so it would correctly calculate a block group's
448 checksum field field on 64-bit systems.
450 E2fsck now has a much more understandable error message when the
451 journal superblock is corrupt and the user declines to fix it.
452 (Addresses Debian Bug: #768162)
454 Fixed support of extended timestamps on 64-bit systems.
456 Updated/fixed various man pages. (Addresses Debian Bugs: #766379,
457 #761144, #770750, #428361, #766127)
459 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #825868)
465 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
467 Fixed Android build makefiles (which was missing a newly added file in
470 In general, checks on s_creator_os have been removed in favor of
471 feature flag specific checks; if there is something that can't be
472 checked via the presence of a feature flag, we will simply check
473 whether the creator OS is *not* EXT2_OS_HURD which is the one
474 operating system where there has been extensive abuse of the
477 The libmagic library has been suppressed when running the regression
478 test suite to avoid false test failures caused by differences between
479 versions of libmagic (and/or the magic number database).
481 The tests/test_script program now accepts the --failed option, which
482 will run those tests that had previously failed.
484 Fixed tests build on those systems which require LDFLAGS to be set.
486 Fixed the regression test suite so it will properly filter out version
487 numbers with two components (such as 1.43) from log files before
488 comparing them with the expected golden output.
491 E2fsprogs 1.43 (May 17, 2016)
492 =============================
494 Add support for the ext4 metadata checksum, checksum seed, inline
495 data, encryption, project quota, and read-only features.
497 Support for the very old, experimental, and never-added-to-mainline
498 compression feature has been removed.
500 Mke2fs will now create file systems with the metadata_csum and 64bit
501 features enabled by default.
503 The mke2fs program will now support multiple -O options (instead of
504 just ignoring all but the last -O option).
506 Mke2fs will now correctly determine the size of a file system and
507 handle the discard operation correctly when the "-E offset=NNN" is
508 used. (Addresses Debian Bug: #803629)
510 The tune2fs program will ask the user for confirmation before starting
511 dangerous operations if the terminal is available, and it will replay
512 the journal if necessary.
514 Add an ext2/3/4 FUSE server
516 Debugfs can now modify extended attributes and journal transactions.
518 Debugfs now can properly display and set extended timestamps.
520 E2fsck will offer to fix extended timestamps that were incorrectly
521 encoded by older kernels.
523 Fix miscellaneous MMP bugs in debugfs.
525 Fix sparse_super2 bugs in mke2fs and resize2fs.
527 Fix or improve offset support in mke2fs, e2undo, and libext2fs.
529 The resize2fs command can now convert file systems between 64-bit and
532 Fix potential out-of-bounds memory access in resize2fs when doing a
533 large off-line file system grow operation.
535 We now use a new e2undo file format which is much more efficient and
536 faster than the old tdb-based scheme. Since it so much faster,
537 e2fsck, tune2fs, debugfs, and resize2fs now also can support using
538 creating an undo file.
540 The mke2fs command can now set the error behavior when initializing
541 the file system (so the administrator doesn't have to issue a separate
544 Teach mke2fs to parse a human-readable argument for -i option.
546 Teach mke2fs to automatically handle creating file systems > 500T by
547 automatically enable the meta_bg feature.
549 Mke2fs will now prompt for user verification before rewriting a file
550 system's superblock using the -S option.
552 Mke2fs no longer complains if the user tries to create a file system
553 using the entire block device (e.g., without using a partition). The
554 minor number convention is not used by all block devices, and it's
555 quite normal in some circumstances to create a file system on /dev/sdc
556 instead of /dev/sdc1.
558 Fix an "mke2fs -d" bug which could create inodes with invalid
559 extended attribute blocks
561 E2fsck is now much more paranoid about not freeing or corrupting
562 critical metadata blocks, such as inode table blocks, even if
563 corrupted indirect blocks or extent trees point at these blocks.
565 E2fsck now prints block ranges in pass1b instead of listing all of the
568 E2fsck will try to expand the root directory if the lost+found can't
569 be linked to the root directory. Also, offer to use the root
570 directory if lost+found can't be created.
572 E2fsck is now more paranoid handling corrupted extent trees as well as
575 E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
576 to recover from a corrupted extent tree, or (c) to convert
577 block-mapped inodes to use extents.
579 E2fsck now has a readahead mechanism which can significantly speed its
580 performance, especially on RAID arrays.
582 E2fsck now has a "yes to all" option which the user can give if she is
583 tired of answering 'y' to a very large number of questions.
585 E2fsck will now ignore the badblocks inode if the contents of the
586 badblocks inode indicate that the portion inode table containing the
587 badblocks inode is bad. (We must go deeper...)
589 E2fsck can now correctly fix directory with holes on bigalloc file
592 E2fsck will now check for extent mapped inodes with no extent header
593 and clear them if found.
595 E2fsck now checks to make sure the extended attribute header doesn't
596 result in the xattr extending beyond the bounds of the inode
598 Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
599 revoke records if the journal is corrupted.
601 Fixed a bug in e2fsck which could cause it loop forever if a special
602 inode has too many invalid block mappings.
604 Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
605 confused if an attempt to allocate a block can't find any free space
608 E2fsck will no longer try to force rewrite blocks located beyond the
611 The e2fsck program will no longer update the quota inodes when it is
614 Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
615 extent-mapped directory.
617 Fixed a bug in resize2fs which could lead to resize2fs crashing or a
618 corrupted file system if the file system is almost completely full
619 when trying grow a file system and we need to allocate blocks to grow
620 the block group descriptors.
622 Fixed a bug in resize2fs which could cause it to get fooled trying to
623 determine the RAID array's stride when flex_bg is enabled.
625 Fix resize2fs bug that could leave block allocation bitmaps
628 The dumpe2fs output has been improved so it is cleaner and always fits
629 within 80 columns. Also added a more easily machine-parsable output
632 The mke2fs program can now pre-populate a file system from a directory
633 hierarchy using the -d option.
635 The mke2fs program now skips zeroing inode table blocks if they were
636 already zeroed using the discard feature.
638 Check to make sure file system features which can not be supported by
639 HURD are not enabled if the file system is created to be
642 Added a new e2fuzz command that will fuzz an ext4 image for testing
645 The debugfs logdump command can now deal with 64-bit revoke tables
646 correctly. Also, "logdump -O" will print the old log contents (before
647 the journal was replayed).
649 The debugfs bmap command can now be used to set or allocate a physical
652 Fixed a bug so "filefrag -B -e -v" does not return a separate entry
655 The filefrag program now accounts for holes in sparse files created by
656 the file punch operation as an expected/optimal mapping.
658 The file I/O functions now correctly handle inodes containing
659 uninitialized blocks.
661 Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
662 file system won't result in corrupted block bitmaps.
664 Updated/fixed various man pages. (Addresses Debian Bug: #798425)
670 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
672 Added Android build files so that e2fsprogs can be built in the
675 Reduce the use of libc functions in libext2fs that may not be present
676 in the boot loader environment, at least for those functions that are
677 needed by boot loaders such as yaboot.
679 Developers can now override the debugging and optimization flags by
680 redefining the CFLAGS makefile macro.
682 The libext2fs library now has support for fallocate.
684 The mke2fs command will now ask the user for confirmation if block
685 device or image file contains an existing file system image, and
686 stdout and stdin are connected to a tty.
688 The libext2fs library now picks a more intelligent goal block when
689 doing block allocations.
691 The libext2fs library will now automatically set the BLOCK_UNINT flag
692 if all of the blocks in a block group are free, to speed up future
693 e2fsck and dumpe2fs operations on the file system.
695 Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
698 The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
701 The ext2fs_bmap() function supports new flags BMAP_UNINIT and
704 The ext2fs_new_block2() function will now call the alloc_block hook
705 before checking fs->block_map.
707 Support for the MMP feature can now be disabled at compile time.
709 Added support to manipulate extended attributes to libext2fs.
711 Added a lot of new regression tests.
713 Added endian annotations so it's possible to scan e2fsprogs for endian
714 problems using a static code analyzer.
716 Fixed memory leaks in libext2fs.
718 The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
719 There is now a script in the contrib directory which automates most of
722 The build system will now run cppcheck (a static code analysis tool)
726 E2fsprogs 1.42.13 (May 17, 2015)
727 ================================
729 Fixed a potential buffer overflow while closing a file system in
730 libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
732 Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
733 (Addresses Debian Bug: #760275)
735 Fixed a deadlock which occurs when using systemd and e2fsck.conf's
736 logging feature. (Addresses Debian Bug: #775234)
738 Fixed a bug which could cause programs using libext2's inode table
739 scanning functions from crashing on certain corrupted file systems.
740 (Addresses Debian Bug: #773795)
742 Fixed dumpe2fs so it won't crash if the user doesn't specify a block
743 device (file system). (Addresses Debian Bug: #764293)
745 Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
746 will report the correct directory inode containing the inconsistency.
748 If e2fsck fails to grow the dir_info structure due realloc(3) not
749 having enough memory, it will now fail with explanatory message
750 instead of staggering on failing with a confusing internal error
753 The tune2fs program will zero out the superblock journal backup
754 information when removing a journal from a file system.
756 The mke2fs program now enables the large_file feature by default.
758 Fixed a bug which could cause badblocks to crash if there are millions
759 and millions of bad blocks.
761 Fixed some use-after-free bug in resize2fs and e2fsck.
763 Fixed a memory leak in tune2fs.
765 Fixed some bigendian bugs that had crept into both indirect and extent
766 handling inside libext2fs.
768 Updated/fixed various man pages.
770 Update Esperanto, German, and Spanish translations. Added Danish
776 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
778 Clean up some build system problems (build failures with various
779 configure options, fix Posix portability issues, etc.)
781 The functions ext2fs_inode_alloc_stats[2]() and
782 ext2fs_block_alloc_stats[2]() now check the inode and block numbers
783 passed to them, to avoid crashes caused by buggy callers.
785 The libext2fs directory iterator will now check for an invalid
786 directory entry length instead of possibly walking off the end of the
790 E2fsprogs 1.42.12 (August 25, 2014)
791 ===================================
793 Fix various e2fsck bugs when trying to repair bigalloc file systems.
795 E2fsck can now repair a file system with an overly large
796 s_first_meta_bg field, which had previously caused all e2fsprogs
797 programs to crash when trying to open such a file system.
799 Fix e2fsck so that it can correctly fix a number of rare file system
800 corruptions that were discovered when using a file system fuzzer.
802 Fix e2fsck so it does not try to write back block group descriptors if
803 they have not been modified.
805 Mke2fs program will now place metadata blocks in the last flex_bg so
806 they are contiguous. This reduces free space fragmentation in a
807 freshly created file system, as well as allowing mke2fs commands which
808 request extremely large flex_bg size to succeed.
810 Mke2fs now creates hugefiles more efficiently (with fewer extent tree
813 Fix a 32/64-bit overflow bug that could cause resize2fs to loop
814 forever. (Addresses-Launchpad-Bug: #1321958)
816 The resize2fs program will now use much less memory when resizing very
819 Fix a bug which could cause resize2fs to get confused and produce a
820 corrupted file system when shrinking a file system that had been
821 previously expanded and converted to use the meta_bg file system
822 format, but which no longer needs to use the meta_bg file system
823 format any longer. This typically happened with large (> 16TB) file
824 systems. (Addresses Debian Bug: #756922)
826 The e4defrag program will now defrag backwards-allocated files.
828 Fix tune2fs updating UUID's when manipulating file systems with
829 external journals (both the file system and journal UUID).
831 Fix tune2fs so it can remove an external journal for file systems with
834 Add a new debugfs command, "inode_dump", which prints the inode in hex
837 The debugfs's "set_inode_field" will now automatically allocate blocks
838 for indirect blocks and extent tree blocks.
840 Fix debugfs's "set_inode_field" so can properly handle
841 "block[IND|DIND|TIND]".
843 The debugfs "rdump" command will now take multiple source arguments.
845 Fixed a double close(2) bug in "rdump" and "rdump -p".
847 Fix debugfs's argument parsing for the freefrag command.
849 Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
850 (Addresses Launchpad Bug: #1356496)
852 Clarified messages that were confusing users in debugfs, e2fsck,
853 mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
856 Dumpe2fs will now complain if extra arguments are given to it.
857 (Addresses Debian Bug: #758074)
859 Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
861 Update Czech, Dutch, French, Polish, Spanish, Swedish, Ukrainian, and
862 Vietnamese translations.
867 The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
868 number of system calls issued.
870 Fixed profiled build.
872 The libext2fs library will now more efficiently split an extent tree
873 index block when appending to an end of a file.
875 Fixed free block accounting for 64-bit file systems.
877 Add a new function ext2s_inode_size_set() which takes care of all of
878 the required feature flag modifications.
880 The regression tests no longer require the presence of the md5sum
883 Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
886 Fix various Coverity warnings (#1225003, #1229243, #1252003)
889 E2fsprogs 1.42.11 (July 9, 2014)
890 ================================
892 Add support so that mke2fs can create hugefiles so that they are
893 aligned relative to the beginning of the disk, instead of relative to
894 the beginning of the partition, using the mke2fs.conf configuration
895 parameter "hugefiles_align_disk".
897 Fix a bug which causes e2fsck to abort a journal replay on a file
898 system with bigalloc enabled. (Addresses Debian Bug: #744953)
900 Add sanity checks so that mke2fs will refuse insanely large flex_bg
901 counts specified by the -G option. Insanely large flex_bg sizes can
902 result in a file system which can't be unmounted, or with extremely
903 pessimal metadata layouts.
905 The mke2fs program will provide a better metadata layout for
906 moderately large (but believable) flex_bg counts, such as 133,072.
908 The mke2fs program will also check the kernel version number to
909 determine whether the lazy_itable_init option is supported, so that
910 lazy inode table initialization can be used even if the ext4 is
911 compiled as a module which isn't loaded at the time that mke2fs is
914 Add description of ext4's mount options to the ext4 section 5 man
917 Improve the chattr man page and clean up the chattr usage message.
919 E2fsck will now automatically fix a last mount time or last write time
920 which is in the future in preen mode, instead of aborting the fsck
923 Mke2fs will now check the file system revision number requested by the
924 command line, and reject it if it is too large. A file system with an
925 unsupported revision number will not be accepted by any of the other
926 file system tools, and this command line option is rarely used, so
927 let's try to help the user not shoot their own foot off.
929 The debugfs program can now set the error count and associated
930 first_error and last_error fields in the superblock using the
931 set_super_value command.
933 Resize2fs will not try to calculate the minimum size of a file system
934 if it contains errors. Otherwise a very badly corrupted file system
935 image can cause the minimum size calculation to loop forever. Since
936 resize2fs will not allow a file system marked as containing errors to
937 be resized. It's pointless to calculate the minimum size, so just
940 Fixed a typo in one of mke2fs's error message.
942 If filefrag runs into an error, it will continue processing the rest
943 of the files specified on the command line, but then exit with an
946 Filefrag now prints some additional new flags (such as
947 FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
949 Fixed support in filefrag for files with > 2**32 blocks on 32-bit
952 Fixed a file descriptor leak in debugfs when copying files.
954 Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
955 to create file systems larger than 2GB on 32-bit platforms.
956 (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
958 Add Esperanto and Ukrainian translations, and update Czech, Dutch,
959 French, German, Italian, Polish, Swedish, and Vietnamese
962 Fixed various compiler warnings.
968 The gcc "-checker" option has been long deprecated, so remove support
969 from e2fsprogs. It was causing a few people to be confused when they
970 tried enabling the configure option.
972 Update to the latest version of the config.status and config.rpath
973 files, as well as newer versions of the autoconf files in aclocal.m4.
974 Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
975 people who want to use autoreconf to do so.
977 Make the use of strptime() function in debugfs to be more portable to
978 fix regression test failures for FreeBSD and MacOS.
980 A few miscellaneous changes designed to make life easier for
983 Fix the f_quota test and some Makefile dependencies if quota support
986 Fix cross-compilation support, which got broken in 1.42.10.
987 (Addresses Debian Bug: #753375)
989 Delete lib/ext2_types.h on a make clean, and build it as necessary.
991 Add a debug program used for libext2fs unit tests.
993 Clean up the tests so that it avoids using GNU-specific behaviour in
994 mktemp. Make sure the temporary files are cleaned up if the tests are
997 Add a new ext2fs_close_free() helper function which automatically
998 takes care of freeing the ext2_filsys structure even if ext2fs_close()
1002 E2fsprogs 1.42.10 (May 18, 2014)
1003 ================================
1005 Mke2fs now creates file systems in regular files (which is very often
1006 used when maintaining virtual machine images) without requiring the
1007 user to use the force option. In addition, the mke2fs output has been
1008 made much less verbose and only displays information that users will
1009 be more likely to find useful by default.
1011 Mke2fs now will ask the user to confirm that they want to continue
1012 before wiping out a pre-existing file system, partition table, or LVM
1015 Mke2fs now has the ability to create file systems where all the
1016 metadata is located at the very beginning of the device. This can be
1017 useful for flash devices which have SLC flash at the beginning of the
1018 disk, for FAT compatibility, for example. As part of this, mke2fs and
1019 tune2fs can control the location of the data blocks used by the
1020 journal inode. In addition, the new sparse_super2 feature allows for
1021 even fewer (anywhere from zero to two) backup superblocks.
1023 Mke2fs now uses much less CPU when allocating the blocks used for very
1026 Mke2fs can now support creating a file system at an offset. This can
1027 be useful when creating a disk image for virtual machines (Addresses
1028 Debian Bug: #497984)
1030 Previously, e2fsck had a number of very serious bugs when checking a
1031 file system which used the new the quota file system option (where the
1032 quota inodes were stored in hidden inodes) and the quota inode was
1033 inconsistent with the actual usage data. This problem was documented
1034 in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
1035 been fixed in 1.42.10, so the quota should be safe to use with
1038 Fixed in a bug in resize2fs which could cause shrink operation fail in
1039 the unlikely situation when the inode table needs to be moved to a
1040 location before the current location.
1042 Resize2fs now has a much more accurate (and less conservative)
1043 estimation of how far the file system can be shrunk. This allows a
1044 mostly empty filesystem which is a few terabytes, to be shrunk to a
1045 few megabytes in a single resize2fs -M operation.
1047 E2fsck will now force a full file system check if there are any file
1048 system inconsistencies detected in the super block.
1050 The filefrag program will now display the shared extent flag, which is
1051 used by file systems such as btrfs.
1053 If the number of inodes in the file systems is larger than the time
1054 that file system was created (as measured by the number of seconds
1055 since January 1, 1970) e2fsck would print a scary (but otherwise
1056 harmless) warning of file system corruption for each inode in the
1057 orphan list. This false positive has been fixed.
1059 The e4defrag program has been fixed so it will no longer refuse with
1060 filesystem with the 64-bit or the bigalloc feature enabled.
1062 The logsave program will print a much less scary message which could
1063 lead users to believe something has gone very wrong with e2fsck exits
1064 with a non-zero exit status (since this is normal after e2fsck has
1065 automatically fixed a file system corruption during a preen
1066 operation). (Addresses Debian Bug: #468821)
1068 When creating a file system which is larger than 16TB, the
1069 resize_inode option must be disabled -- since the resize_inode simply
1070 doesn't support reserving metadata block numbers which is larger than
1071 32 bits. The mke2fs program does this automatically if the file
1072 system size is determined automatically. It will now also do this if
1073 the file size is specified explicitly.
1075 Fixed bugs associated with resize2fs and shrinking bigalloc file
1078 The e2fsck program will no longer try to add a UUID on a mounted file
1079 system with checksums enabled, since this could leave the file system
1082 Tune2fs will allow the removal of an external journal from file system
1083 which is marked as needing the journal replayed when the force ("-f")
1084 option is given twice. (Addresses Debian Bug: #559301)
1086 Tune2fs will no longer support enabling sparse_super if the meta_bg
1087 file system feature is enabled, since it could result in data loss.
1088 In practice, all modern file systems have sparse_super is enabled, so
1089 it's not worth trying to change how tune2fs handles enabling the
1090 sparse_super feature.
1092 Fixed support for 1k block file systems with the meta_bg feature.
1094 When the superblock is corrupt, e2fsck can't figure out the location
1095 of the alternate superblock. Unfortunately, the routine that
1096 calculates the location of the alternate superblock uses 8193 if it
1097 can't figure this out, so the message printed by e2fsck always
1098 suggests using "e2fsck -b 8193". This message has been fixed to
1099 suggest both the superblock location of 8193 and and 32768.
1100 (Addresses Debian Bug: #719185)
1102 The lookback mount detection code that was introduced in 1.42.9 wasn't
1103 actually compiled in due to an autoconf oops, so it's fixed now in
1104 1.42.10. (Addresses Debian Bug: #497984)
1106 A bug introduced in 1.42.9 would cause debugfs to print two error
1107 messages if it found an error while parsing a user-supplied block
1108 number. This has been fixed in 1.42.10.
1110 Update Czech, Dutch, French, German, Polish, Spanish, Swedish, and
1111 Vietnamese translations. (Addresses Debian Bug: #703048)
1113 Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
1116 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
1122 Fixed a lot of coverity, sparse, gcc -Wall, and clang warnings/nits.
1124 Allow the location of pkg-config files to be specified independent of
1125 the libdir location via a makefile variable.
1127 Fixed parse-types.sh not to complain when cross-compiling and the
1128 sizes of types are different between the target architecture and the
1129 architecture of the build system
1131 Allow the regression test suite to work correctly on systems which do
1132 not have the "truncate" or "mksawp" programs.
1134 Allow e2fsck to build correctly on systems (such as Android) that do
1135 not have the signal.h file.
1137 E2fsprogs now has code coverage testing which can be enabled using
1138 "configure --enable-gcov".
1140 The libe2p.h header file can now be used included by C++ programs.
1142 The profile/config file used by e2fsck and mke2fs will interpret
1143 numbers with a leading 0 character to mean that they should be
1144 interpreted as an octal integer.
1146 The extent handling functions in libext2fs have been improved so they
1147 have proper rollback when there is an error splitting an extent. Also
1148 fix a number of bugs when punching holes in files, and fix an
1149 off-by-one bug when inserting an extent into an empty inode.
1151 The libext2fs library now handles the support of BLOCK_UNINIT by
1152 clearing the portion of block bitmap when it is loaded, instead of
1153 when it is used. This reduces the chances of bugs, and and simplifies
1154 the code. It also means that debugfs will properly show that blocks
1155 in uninitialized block groups as being unused when using the testb
1158 The e4defrag program will try to use fadvise64 or posix_fadvise64() if
1159 it is present, which allows 64-bit offsets on 32-bit systems.
1162 E2fsprogs 1.42.9 (December 28, 2013)
1163 ====================================
1165 Mke2fs will detect an attempt to create a file system on a loop
1166 mounted file and complain without the -FF option. Also fixed mke2fs
1167 so it allows the creation of a file system on a mounted device with
1168 two -F options, as documented in the man page, instead of three -F
1171 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
1172 libext2fs to correctly handle bigalloc and 64-bit file systems. There
1173 were many corner cases that had not been noticed in previous uses of
1174 these file systems, since they are not as common. Some of the bugs
1175 could cause file system corruption or data loss, so users of 64-bit or
1176 bigalloc file systems are strongly urged to upgrade to e2fsprogs
1179 The tune2fs program will now not allow changing the uuid on a mounted
1180 file system which has the uninit_bg feature enabled. This avoids a
1181 nasty race where the kernel and tune2fs are both retrying rewrite the
1182 group descriptors at the same time, with different ideas about what
1185 When e2fsck is rehashing an extent-mapped directory, it's possible
1186 (although very rare) that an extent block will need to be allocated;
1187 fix e2fsck to make sure that the block gets marked as used.
1189 Mke2fs will now properly set the LARGE_FILE feature when creating a
1190 journal >= 2GB --- which can happen when using 64k block size.
1192 Fixed debugfs so that its freei command will correctly handle a request
1193 to free a range of consecutive inodes.
1195 Fixed 2fsck so it will not erroneously complain that an external journal
1196 is invalid if it is exactly 2**32 blocks.
1198 Fixed e2fsck so it won't try checking for, and adding, a missing
1199 lost+found directory when running in read-only mode.
1201 Fixed e2image so that progress information won't get leaked to stdout.
1202 (Addresses Red Hat Bugzilla: #1327329)
1204 Fixed e2image to avoid some buffer overruns which would cause it to when
1205 creating a "standard (non-raw, non-qcow2) image file. Standard
1206 e2image files are actually very rarely used, so we didn't notice when
1207 the changes to enable the qcow2 format broke this e2image mode.
1209 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
1210 on the resize_inode feature when the meta_bg feature is set, since
1211 these two features can not be set at the same time.
1213 Fixed tune2fs so that when it disables the quota feature, it updates all
1214 of the backup superblocks.
1216 Fixed dumpe2fs that would cause it to abort when run using an image file
1217 when trying to print the journal information (which is not present in
1218 an e2image created image file).
1220 Fixed a potential integer overflow in e2reefrag.
1221 (Addresses-Debian-Bug: #718205)
1223 Enhance debugfs so that when copying a sparse file from a native file
1224 system into the file system image using the "write" command, it will
1225 create a sparse file into the destination file system.
1227 Enhanced debugfs so it can support a command line which is up to 8k
1230 E2image will refuse (unless the -f option is specified to force the
1231 issue) to create a raw or qcow image using a mounted file system,
1232 unless the -f option is specified to force the issue.
1234 E2image has been optimized for using it to efficiently copy a file
1235 system by only copying the allocated blocks, by using the options -ra.
1236 New options (-o and -O) have been added so that a source and
1237 destination offset can be given. The -p option will print progress
1238 information so the user will know how far along the copy is going.
1239 And finally, the new option -c is useful for updating a file system on
1240 an SSD, by avoiding unnecessary writes. E2image can also shift a file
1241 system image by doing an in place move.
1243 Fix a regression introduced in 1.42.8 which would cause e2fsck to
1244 erroneously report uninitialized extents past the EOF (as determined by
1245 i_size) to be invalid.
1247 Fixed resize2fs so under a corner case when an inode has a complex
1248 extent tree, it will not corrupt an interior node in the extent tree.
1250 Fixed resize2fs which would sometimes corrupt a file system when
1251 shrinking a file system to a minimum size using resize2fs -M.
1252 (Addresses Debian Bug: #660793)
1254 Fixed resize2fs so that it will relocate inode table blocks if this
1255 becomes necessary when shrinking the file system.
1257 Fixed resize2fs and e2fsck so they will not crash when hit a failure
1258 while operating on a file system with the MMP feature enabled.
1260 Fixed a bug in debugfs which caused it create an invalid inode when
1261 trying to write a zero-length file.
1263 E2fsck will no longer crash if it tries to delete an invalid
1264 extent-mapped symlink.
1266 E2fsck will no longer crash if it comes across an directory which is
1267 larger than 2GB (which is not allowed in valid file systems).
1269 Fixed debugfs's help texts to fully document all options and otherwise
1272 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
1275 Fixed various Debian Packaging Issues (#698879, #721365)
1281 Fix sparse, gcc -Wall and clang nits.
1283 Update config.{guess,sub} to the latest version
1285 Fixed various memory and file descriptor leaks on various error paths,
1286 as well as some missing error return checks, which were found using
1289 Run sparse against source files when building e2fsprogs with 'make
1290 C=1'. If instead C=2, it configures basic ext2 types for bitwise
1291 checking with sparse, which can help find the (many many) spots where
1292 conversion errors are (possibly) happening.
1294 Allow the regression test to be run in chrooted environments where
1295 /etc/mtab might be missing.
1297 The ext2fs_punch() function, which was introduced in 1.42, was broken
1298 in many ways, but this was never noticed since it wasn't used for
1299 anything significant. Some of the bugs include failing when trying to
1300 punch a completely sparse file, failing when punching an extent-mapped
1301 inode when the starting block was at the beginning of the inode, and
1302 not being able to punch a single block (where start_blk == end_block).
1303 It also didn't handle being passed an invalid, too-large ending block
1304 number, and didn't handle properly terminate at the right place when
1305 operating on an indirect-mapped inode.
1307 Fixed some minor typo's in the error catalog for libext2fs.
1309 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
1310 setting the file size, to zero the rest of the block to the end of the
1311 file, so that if an ext4 FUSE driver tries to extended the file, that
1312 we don't avoid stale data from being returned.
1314 Fixed ext2fs_bmap() to disallow clients from trying to map or set
1315 logical blocks which are larger than what an extent-mapped or indirect
1316 block-mapped inode can allow.
1318 If debugfs (or some userspace program using libext2fs) creates a file
1319 which is larger than 2GB, make sure the large_file feature flag gets
1322 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
1323 directory which are large enough, the directory entry could get
1324 inserted more than once in the directory.
1326 If quota support is disabled (which is the default), make sure that
1327 all traces of the quota support is removed from usage messages, man
1328 pages, and tune2fs must not be able to enable the quota file system
1329 feature. (Addresses Red Hat Bugzilla: #1010709)
1331 The ext2fs_file_write() now updates i_size on a successful write,
1332 instead of only updating i_size wen the file is closed via
1333 ext2fs_file_close().
1335 Added a shell script, populate-extfs.sh which uses debugfs to populate
1336 an ext2/3/4 file system image from a given directory. It is similar
1337 to the genext2fs program, but it supports ext3 and ext4 file system.
1339 Add changes to the libext2fs library to support block group
1340 descriptors larger than 64 bytes (for future compatibility).
1342 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
1343 leave an extra block in the file when truncating the file down to
1346 The html version info pages are now built using makeinfo --html
1347 instead of the unmaintained and now-obsolete texi2html program.
1350 E2fsprogs 1.42.8 (June 20, 2013)
1351 ================================
1353 As a part of mke2fs's option parsing cleanup, the use of the -R option
1354 will give a warning that it is deprecated (it has been so documented
1355 since 2005) and -E should be used instead.
1357 Mke2fs will not give warnings about the bigalloc and quota options in
1360 If an invalid journal size is given to mke2fs, it will now complain
1363 Debugfs was erroneously giving spurious error messages for certain
1364 extent_inode subcommands which take arguments (split_node,
1365 replace_node, and insert_node). This has been fixed.
1367 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
1368 other programs is used by mke2fs.
1370 Change mke2fs so that it does not set the root directory to the real
1371 uid/gid of the mke2fs process. Add the extended option root_owner to
1372 override this behavior.
1374 Fix resize2fs when shrinking file systems to make sure that bitmap
1375 blocks aren't left outside the bounds of the shrunken file system.
1376 This could happen with flex_bg file systems that were grown using
1377 the old online resizing algorithm.
1379 E2fsck will now detect and repair corrupted extent trees which contain
1380 invalid extents at the end of the extent tree leaf block.
1382 E2fsck will now longer complain about zero length extended attribute
1385 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
1388 Add safety check so tune2fs will not attempt to set the inode size to
1389 be larger than the block size.
1391 Fix e2fsck so it can check a read-only root file system with an
1392 external journal. (Addresses Debian Bug: #707030
1394 Fix off-line resizing of file systems with flex_bg && !resize_inode
1395 (Addresses Debian Bug: #696746)
1397 Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
1400 Enhance chattr to allow clearing the extent flag if the kernel allows
1401 migrating extent based files to use indirect blocks.
1403 Update German translation.
1405 Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
1408 Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
1413 Use secure_getenv() in preference to __secure_getenv().
1415 Optimize CPU utilization of ext2fs_bg_has_super().
1417 Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
1418 SEEK_CUR is used with large files.
1420 The ext2fs_read_inode_full() function will no longer use
1421 fs->read_inode() if the caller has requested more than the base 128
1422 byte inode structure and the inode size is greater than 128 bytes.
1424 Fix build failure with --enable-jbd-debug.
1426 Clean up filtering of outputs for the regression tests by using a
1429 Fix gcc -Wall and clang nits.
1432 E2fsprogs 1.42.7 (January 21, 2013)
1433 ===================================
1435 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
1436 quota features are still under development. For more information
1438 * https://ext4.wiki.kernel.org/index.php/Bigalloc
1439 * https://ext4.wiki.kernel.org/index.php/Quota
1441 Add some new options to filefrag from Lustre's patches to e2fsprogs:
1442 * add -k option to print extents in kB-sized units (like df -k)
1443 * add -b {blocksize} to print extents in blocksize units
1444 * add -e option to print extent format, even when FIBMAP is used
1445 * add -X option to print extents in hexadecimal format
1447 Fix resize2fs so that it can handle off-line resizes of file systems
1448 with the flex_bg feature but without a resize_inode (or if we run out
1449 of reserved gdt blocks). This also fixes a problem where if the user
1450 creates a filesystem with a restricted number of reserved gdt blocks,
1451 an off-line resize which grows the file system could potentially
1452 result in file system corruption.
1454 Fix a resize2fs bug which could cause it to corrupt bigalloc file
1455 systems when doing an off-line resize.
1457 Further optimize resize2fs so it doesn't use quite as much CPU when
1458 resizing very large file systems.
1460 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
1461 possibly corrupt the file system while resizing 64-bit file systems.
1463 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
1464 mke2fs crash due to a divide-by-zero if the 64bit file system feature
1467 Add better error checking to mke2fs to check for invalid parameters
1468 when creating bigalloc file system.
1470 When creating bigalloc filesystems, the -g option to mke2fs will now
1471 specify the number of clusters per block group.
1473 Add to debugfs the functionality to corrupt a specific file system
1474 block via the "zap_block" command.
1476 Add to debugfs the functionality to print out a hex dump of a block in
1477 the file system via the "block_dump" command.
1479 Add to debugfs the functionality to manipulate the extent tree
1480 directly via the "extent_open" command.
1482 Fixed debugfs's mknod command so that it updates the block group
1485 Fix e2fsck so it can detect and fix inconsistencies in the interior
1486 nodes of an inode's extent tree.
1488 Fix a potential memory corruption failure in e2fsck's error path if
1489 the call to ext2fs_open2() fails.
1491 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
1492 resulting file name for the log file is longer than 100 bytes, that it
1493 properly handles this situation instead of crashing.
1495 E2fsck will now report the amount of memory that it attempted to
1496 allocate when a memory allocation request fails, to make it easier to
1497 track down the problem.
1499 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
1500 Lustre Bug: LU-1888)
1502 E2image can now include all data blocks in the e2image output file
1503 when the user specifies the -a option.
1505 If e2fsprogs is compiled without --enable-quota, make sure that
1506 tune2fs can not turn on the feature for new-style quota support, since
1507 afterwards, none of the e2fsprogs tools will be willing to touch that
1510 Optimize e2fsck's so that it uses much less CPU for large file
1511 systems. This can result in significant speedups, especially on
1512 CPU-constrained systems. This was primarily done by optimizing
1513 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
1515 Fix debugfs's htree command so that all its messages are sent through
1518 Fixed debugfs's "dump_file" and "cat" functions work correctly
1519 on file systems whose block size is greater than 8k.
1521 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
1522 less memory. (Addresses Google Bug: 7269948)
1524 Update the spd_readdir.c file in the contrib directory to include some
1525 additions which were made in 2008 that didn't get folded into the
1526 version which we checked into the e2fsprogs source tree. These
1527 enhancements include thread safety, support for readdir64_r(), and
1528 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
1530 Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
1533 Add a command to debugfs to create symlinks.
1535 Document the bigalloc feature in the mke2fs man page. (Addresses
1536 Debian Bug: #669730)
1544 Fix a spelling typo in the libext2fs texinfo documentation.
1546 Change the output from "make check" so that tools such as emacs's "M-x
1547 compile" does not mistake the output as containing a compiler error.
1549 Export two new functions from libext2fs: ext2fs_extent_node_split()
1550 and ext2fs_extent_goto2().
1552 The ext2fs_extents_fix_parents() was fixed so it does not modify the
1553 location of the extent handle if its current location is at an
1554 interior node, rather than a leaf node of an inode's extent tree.
1556 Add a regression test to assure that e2fsck can correctly fix an
1557 inconsistent interior node in an inode's extent tree.
1559 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
1560 correctly support bigalloc file systems which use store block usage
1561 information in units of clusters.
1563 Fixed the help text in the configure script for --enable-quota.
1565 The m68k-specific bitops code has been removed since they were
1566 incorrectly treating bit numbers with the high bit set as signed
1567 integers. Furthermore, modern compilers do a good enough job
1568 optimizing the generic code there is no point in having the m68k
1569 specific asm statements.
1571 Fixed how we link the test programs so they always use the static
1572 libraries, so that we test using the libraries which we have just
1575 Update config.guess and config.sub to the latest versions from the GNU
1578 Fixed the com_err.texinfo file so that it can produce a valid
1579 postscript/pdf printed output.
1581 Add a regression test which checks debugfs's ability to create
1582 symlinks, named FIFO's, and device nodes.
1584 Add a function ext2fs_symlink(), which creates symlinks to the
1587 Add debugging code so we can test old kernel interfaces for online
1588 resize to resize2fs. This backwards compatibility checking is keyed
1589 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
1590 test the functionality of the kernel's older resize ioctls without
1591 needing to install an old version of resize2fs, and to also test a
1592 modern resize2fs's ability to work with older kernels without having
1593 to install an older version of the kernel.
1596 E2fsprogs 1.42.6 (September 21, 2012)
1597 =====================================
1599 When mke2fs creates file systems with lazy itable initialization, the
1600 progress updates for writing the inode table happens so quickly that
1601 on a serial console, the time to write the progress updates can be the
1602 bottleneck. So mke2fs will now only update its progress indicators
1605 Resize2fs will skip initializing the inode tables if the kernel
1606 supports lazy_itable_init, which speeds up growing off-line growth of
1607 uninit_bg file systems significantly. Resize2fs will now also
1608 correctly set the itable_unused field in the block group descriptor to
1609 speed up the first e2fsck after the file system is grown.
1611 Resize2fs has been fixed so that on-line resizing of meta_bg file
1612 systems work correctly. This is needed to grow file system which are
1615 Resize2fs will now correctly handle resizing file systems to 16TB on
1616 32-bit file systems when "16TB" is specified on the command line.
1618 Fix mke2fs so that it will be careful to set the reserved blocks ratio
1619 larger than 50%; this can happen when creating small file systems and
1620 when the last block group is dropped because there are not enough
1621 blocks to support the metadata blocks in the last block group.
1623 Fixed spelling mistake in debugfs's help message.
1625 Fixed a potential seg fault in e2fsck when there is an I/O error while
1626 reading the superblock.
1628 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
1630 Updated/fixed various man pages. (Addresses Sourceforge Bug:
1636 The configure option --enable-relative-symlink was broken so that it
1637 needed to be --enable-symlink-relative-symlinks. We will support both
1638 for at least two years, but then the wrong configure option will be
1641 Fixed a regression introduced in 1.42.5 so the link order for
1642 e2fsprogs' libraries will be correct for both static and shared
1643 linking. (Addresses Sourceforge Bug: #3554345)
1645 Add support for e2fsprogs to be compiled using clang/LLVM.
1647 Fix portability problems on non-Linux systems: avoid compile failures
1648 on systems that don't have malloc.h
1650 Fix f_mmp regression test suite so that debugfs gets killed if the
1651 test is interrupted.
1655 E2fsprogs 1.42.5 (July 29, 2012)
1656 ================================
1658 Fixed a bug with mke2fs where if there is only 8 inodes per block
1659 group, the calculation of the number of uninitialized inodes in the
1660 first block group would go negative. This resulted in "mke2fs -N 256
1661 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
1662 would run out of space. (Addresses Sourceforge Bug: #3528892)
1664 Fixed a bug in how e2fsck would uniquify directory entry names.
1665 (AddressesSourceforge Bug: #3540545)
1667 Previously, e2fsck would only allow a mounted file system to be
1668 checked if it was the root file system and it was mounted read-only.
1669 Now it will allow any file system mounted read-only to be checked if
1670 the -f option is specified. This makes it easier to test how e2fsck
1671 handles checking file systems which are mounted without having to test
1672 on the root file system.
1674 Fixed a problem if e2fsck where if the root file system is mounted
1675 read-only, e2fsck would not clear an error indication in the journal
1676 superblock. Combined with a kernel bug, this would cause the e2fsck
1677 to check the file system after every single boot.
1679 The e4defrag program can now handle device symlinks, such as
1680 /dev/mapper/testvg-testlv, instead of insisting on a less
1681 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
1684 Fixed filefrag so it will not crash with a segfault on files from a
1685 virtual file system such as /proc. (e.g., "filefrag
1688 Fixed filefrag so that it correctly reports the number of extents.
1689 (Addresses Red Hat Bugzilla: #840848)
1691 Fixed a file descriptor leak in logsave which could cause it to hang.
1692 (Addresses Debian Bug: #682592)
1694 Fixed e2fsck so that the file system is marked as containing an error
1695 if the user chooses not to fix the quota usage information.
1697 Fixed tune2fs so that it correctly removes the quota feature when the
1698 last quota inode is removed.
1700 Fix tune2fs so that after removing a quota inode, the block bitmap is
1701 updated; otherwise, e2fsck would complain after running 'tune2fs -O
1704 Fix tune2fs so that when converting a file system from using legacy
1705 quota files to the new quota file system feature with hidden quota
1706 files, the accounting for these files is handled correctly so that
1707 e2fsck doesn't complain.
1709 Improved e2fsck's verbose reporting statistics, and allow the more
1710 verbose reporting to be enabled via /etc/e2fsck.conf.
1712 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
1714 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
1720 Fixed portability problems on other operating systems (e.g., Hurd and
1721 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
1723 Make sure that shared libraries link with the shared libraries built
1724 in the build tree, instead of the system provided libraries.
1725 Previously, libraries and executables were linked with the system
1726 libraries if present, and possibly using static archives instead of
1727 shared libraries. This was also problematic since if libext2fs.so is
1728 linked with a static libcom_err.a from system, the build system would
1729 attempt to link without -lpthread. (Addresses Sourceforge Bug:
1733 E2fsprogs 1.42.4 (June 12, 2012)
1734 ================================
1736 Fixed more 64-bit block number bugs (which could end up corrupting
1737 file systems!) in e2fsck, debugfs, and libext2fs.
1739 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
1740 not properly propagating the journal's s_errno field to the superblock
1741 field; it was not checking this field if the journal had already been
1742 replayed, and if the journal *was* being replayed, the "error bit"
1743 wasn't getting flushed out to disk.
1745 Fixed a false positive complaint by e2fsck if all of the extents in
1746 the last extent tree block are uninitialized and located after the end
1747 of the file as defined by i_size.
1749 The dumpe2fs will now display the journal's s_errno field if it is
1750 non-zero, and it will also display the journal's 64-bit feature flag
1753 Fix e2fsck so that it always opens the device file in exclusive mode
1754 when it might need to modify the file system, and never if the -n
1755 option is specified. (Previously, there were a few corner cases where
1756 it might get things wrong in either direction.)
1758 E2fsck now correctly truncates or deallocates extent-mapped inodes on
1759 the orphan list. The root cause was a bug in libext2fs's block
1760 iterator which could end up skipping an extent when the last block in
1761 an extent is removed, causing the current extent to be removed from
1764 E2fsck now correctly sets the global free block and inode counts when
1765 truncating or removing inodes on the orphan list in preen mode.
1766 Previously, it would leave these values would be set incorrectly,
1767 which is largely a cosmetic issue since the kernel no longer pays
1768 attention to those fields, but it can cause spurious complaints in
1769 subsequent e2fsck runs.
1771 Fix i_blocks accounting when the libext2fs library needs to add or
1772 remove an extent tree block on bigalloc file systems.
1774 The lsattr and chattr programs now support the No_COW flag for the
1777 Debugfs now interprets date strings of the form @ddd as ddd seconds
1778 after the beginning of the epoch. This is handy when setting an inode
1779 number into the d_time field when debugging orphan list handling.
1781 Fix a precedence bug with built-in quota support which might result in
1782 e2fsck paying attention to the quota inode field even if the built-in
1783 quota feature flag is not set. Fortunately, in practice that
1784 superblock field should be zero for non-built-in quota file systems,
1785 so it's unlikely this bug would have caused problems.
1787 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
1793 The regression test suite can now run the integration tests in the
1794 tests directory in parallel, via "make -jN check".
1796 Add new test, f_zero_extent_length which tests e2fsck's handling of
1797 the case where all of the extents in the last extent tree block are
1798 uninitialized extents after i_size.
1800 Add a new test, f_jnl_errno, which checks handling of an error
1801 indication set in the journal superblock.
1803 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
1804 of a 64-bit journal.
1806 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
1807 tests e2fsck's handling of orphan inodes in preen mode, and truncation
1808 of extent inodes on the orphan list.
1810 Fixed more OS X portability issues.
1813 E2fsprogs 1.42.3 (May 14, 2012)
1814 ===============================
1816 Fix a bug in the Unix I/O manager which could cause corruption of file
1817 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
1818 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
1819 dumpe2fs to incorrectly display block numbers > 32-bits.
1821 Improve the support for integrated quota files (where quota is a first
1822 class supported feature using hidden files in the ext4 file system).
1823 Previously the quota file was getting rewritten even when it was not
1824 necessary, and e2fsck would erroneously try to hide quota files which
1825 were already hidden.
1827 Quiet complaints in e2fsck when the total free blocks or inodes are
1828 incorrect in the superblock after an system crash, since we don't
1829 update nor depend on the superblock summaries at each commit boundary.
1831 Fixed a regression introduced in 1.42.2 which would cause applications
1832 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
1833 would were still using the legacy 32-bit bitmaps) to crash. This was
1834 due to missing 32-bit compat code in side the function
1835 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
1838 Fix a bug which would cause mke2fs to fail creating the journal if
1839 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
1842 Updated/fixed various man pages.
1844 Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
1847 Fixed various Debian Packaging issues.
1853 Change the nonsensically wrong types in the function signature of the
1854 inline function ext2fs_find_first_zero_block_bitmap2(). This was
1855 caused by a cut and paste error; fortunately no code in e2fsprogs used
1856 this inline function, and there are any users of this functions
1857 outside of e2fsprogs.
1859 Add support for systems which have valloc(), but which do have
1860 posix_memalign() nor memalign() (such as MacOS 10.5).
1862 Refactor and clean up the allocation of aligned buffers for Direct I/O
1863 support. Previously some allocations were requesting a greater
1864 alignment factor that what was strictly necessary. Also optimize
1865 reading and writing bitmaps using Direct I/O when the size of the
1866 bitmap did not fully cover the file system blocksize.
1868 Reserve the codepoints for the INCOMPAT features LARGEDATA and
1871 Improved the regression test suite by adding some new integration
1872 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
1873 jbd2 format, as well as f_eofblocks which tests the new handling of
1874 uninitialized and initialized blocks beyond i_size. Also add a new
1875 unit test which verifies 32-bit bitmaps support and the new
1876 find_first_zero primitives.
1878 Add a few dependencies to fix parallel (make -j) builds.
1880 Removed bash'isms which were breaking the regression test suite on
1881 systems where /bin/sh is not bash.
1883 The config.guess and config.sub have been updated to the 2012-02-10
1886 Fix a portability problem caused by assuming the present of mntent.h
1887 means that setmntent() exists. Instead, explicitly test for this in
1888 the configure script.
1890 If the sys/signal.h header file does not exist, don't try to include
1891 it, since it's not available on all systems.
1893 Add support for systems that do not support getpwuid_r()
1895 The configure script now supports a new option,
1896 --enable-relative-symlinks, which will install relative symlinks for
1897 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
1899 When building BSD shared libraries make sure the LDFLAGS variable is
1900 passed to the linker. Fixing this allows, for example, e2fsprogs to
1901 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:

1914 argument to set and clear a contiguous range of inodes.

1917 plan to remove support for it from the kernel file system driver. It
1918 really wasn't very useful and was causing more problems than it
1919 solves. Since e2fsck will complain if inodes that should have
1920 EOFBLOCKS_FL do not have the flag set, we are going to remove this
1921 check from e2fsprogs first, and then only remove the flag from the
1924 The mke2fs program can now use direct I/O via "mke2fs -D". This will
1925 slow down the mke2fs, but it makes it more polite on a loaded server
1926 by limiting the amount of memory that gets dirtied by mke2fs when it
1927 is using buffered I/O.
1929 E2fsck was needlessly closing and re-opening the file system as a side
1930 effect of adding Multiple Mount Protection (MMP). This isn't
1931 necessary for non-MMP file systems, so drop it.
1933 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
1934 can more easily diagnose memory allocation failures caused by
1935 insufficient memory. E2fsck will now abort if there are memory
1936 allocation failures when the file system is initially opened and
1937 during the block group descriptor checks. (Addresses Google Bug:
1940 If there are incorrect block group checks, e2fsck will now report the
1941 incorrect and corrected checksum values.
1943 The e2fsck program can now write log files containing the details of
1944 the problems that were found and fixed directly, via configuration
1945 parameters in /etc/e2fsck.conf.
1947 Added the ability to limit the number of messages reported by e2fsck
1948 for a given problem type. This avoids a potential bottleneck if there
1949 is a serial console which can cause a boot sequence to take a long
1950 time if e2fsck needs to report many, many file system errors.
1952 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
1953 them to use much less memory for large file systems.
1955 The dumpe2fs program will now print the expected block group checksum
1956 if it is incorrect. This helps to diagnose problems caused by
1957 incorrect block group checksums.
1959 E2fsck now checks for extents with a zero length, since the kernel
1960 will oops if it comes across such a corrupted data structure. (See
1961 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
1963 E2fsck has a number of bugs relating to discard that have been fixed.
1964 (1) Fixed a bug which could cause e2fsck to discard portions of the
1965 inode table which were actually in use. (2) E2fsck will now avoid
1966 using discard if the block device doesn't zero data on discard, since
1967 otherwise this could cause problems if the file system gets corrupted
1968 in the future. (3) E2fsck will now avoid using discard when it is run
1969 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
1970 discards in the last block group.
1972 E2fsck's CPU utilization in pass 5 has been optimized, which will
1973 speed up e2fsck slightly.
1975 E2image will now skip copying uninitialized bitmap and inode table
1978 Fixed mke2fs -S so it does not corrupt the first block group's
1981 E2fsck will now check the new sysfs interface to determine if we are
1982 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
1984 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
1986 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
1991 Fixed various portability issues for non-Linux systems, particularly
1992 MacOS X, as well as Linux systems running with the just-released glibc
1995 Fix file descriptor leak in ext2fs_close() if the file system with
1996 uninit_bg is opened read/only with a backup superblock. (Addresses
1997 SourceForge Bug: #3444351)
1999 Fixed an invalid return in a non-void function in the quota code.
2000 (Addresses SourceForge Bug: #3468423)
2002 Fixed the debian rules file so that the calls to dpkg-buildflags works
2003 when the shell is dash.
2005 The debian package build now uses V=1 so that there is more
2006 information about potential build failures in debian build logs.
2008 If the uninit flags get cleared by functions such as
2009 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
2010 superblock is marked dirty and the block group descriptor checksum is
2011 updated if necessary.
2013 The debian rules file will now try to load debian/rules.custom of it
2014 exists. This file can skip various builds for speed reasons if there
2015 is no need for the e2fsck-static or udeb packages. Available
2016 customizations in the rules file includes SKIP_STATIC=yes,
2017 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
2019 In addition, if the file misc/mke2fs.conf.custom.in exists in the
2020 source tree, it will be used instead of the standard misc.conf file in
2021 the upstream sources. This makes it easier for Debian-derived systems
2022 to distribute a custom mke2fs.conf file without having to worry about
2023 merge issues if future versions of e2fsprogs makes changes in the
2024 upstream default version of mke2fs.conf.
2027 E2fsprogs 1.42.1 (February 17, 2012)
2028 ===================================
2030 The mke2fs and e2fsck now use significantly less memory when creating
2031 or checking very large file systems. This was enabled by adding
2032 extent-based bitmaps which are stored using a red-block tree, since
2033 block and inode allocations tend to be contiguous.
2035 The command mke2fs -S is used as a last ditch recovery command to
2036 write new superblock and block group descriptors, but _not_ to destroy
2037 the inode table in hopes of recovering from a badly corrupted file
2038 system. So if the uninit_bg feature is enabled, mke2fs -S will now
2039 set the unused inodes count field to zero. Otherwise, e2fsck -fy
2040 after using mke2fs -S would leave the file system completely empty.
2042 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
2043 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
2044 installed an mke2fs binary using that name.
2046 The usage and help messages for the -G, -t and -T options in mke2fs
2049 If e2fsck needs to use the backup group descriptors, the
2050 ext2fs_open2() function clears the UNINIT bits to ensure all of the
2051 inodes in the file systems get scanned. However, the code which reset
2052 the UNINIT flags did not also recalculate the checksum, which produced
2053 many spurious (and scary) e2fsck messages. This has been fixed by
2054 resetting checksums when the UNINIT bits are cleared.
2056 Relax a check in e2fsck which required that the block bitmap to be
2057 initialized when the inode bitmap is in use. This will allow us to
2058 eventually eliminate code from the kernel which forcibly initialized
2059 the block bitmap when the inode bitmap is first used, requiring an
2060 extra journal credit and disk write. (Addresses Google Bug: #5944440)
2062 Make sure rdebugfs (which may be installed setuid or setgid disk) does
2063 not honor environment variables if euid != uid or egid != gid.
2065 Debugfs's ncheck command has been optimized and now is much more
2066 robust with faced with corrupted file systems. The ncheck command
2067 also now has a -c option which will verify the file type information
2068 in the directory entry to see if matches the inode's mode bits. This
2069 is extremely useful when trying to use debugsfs to determine which
2070 parts of the file system metadata can be trusted.
2072 E2image will try to use ftruncate64() to set the i_size for raw
2073 images, instead of writing a single null byte. This avoid allocating
2074 an extra block to the raw image, for those file systems and/or
2075 operating systems that support this. (Linux does.) In addition, fix
2076 a logic bug that caused the file to not be properly extended if the
2077 size of the last hole was exactly an multiple of a megabyte.
2079 Fixed a bug in resize2fs where for 1k and 2k file systems, where
2080 s_first_data_block is non-zero, this wasn't taken into account when
2081 calculate the minimum file system size for use with the -M option.
2083 Fixed the badblocks program to honor the -s flag when in read-only -t
2084 mode. (Addresses Debian Bug #646629)
2086 Update Czech, Dutch, French, Polish, and Swedish translations from the
2087 Translation Project.
2089 Fixed various Debian Packaging issues so that dpkg-buildflags is used
2090 if present, which allows e2fsprogs to be built with security hardening
2091 flags. (Addresses Debian Bugs: #654457)
2096 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
2097 This was only an issue for programs compiled against e2fsprogs 1.41
2098 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
2101 The libext2fs library now uses sysconf() to fetch the page size, instead
2102 of the deprecated getpagesize().
2104 The ext2fs_get_pathname() function will return a partial path if an a
2105 directory in the path is not a directory, displaying it as an inode
2106 number in angle brackets instead of giving up and displaying an error.
2107 This is much more helpful when a user is trying to debug a corrupted
2110 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
2112 Added a new library function, ext2fs_file_get_inode_num(), for use by
2115 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
2116 file, it actually works.
2118 The block iterator now properly honors the BLOCK_ABORT flag for
2119 extent-based flags. Previously, it didn't, which generally made code
2120 be less efficient, but it could cause bugs in ext2fs_link(), for
2121 example, by causing it to insert multiple directory entries.
2123 Fixed an (harmless other than causing a compiler warning) use of an
2124 uninitialized variable in e2fsck's MMP code.
2127 E2fsprogs 1.42 (November 29, 2011)
2128 ==================================
2130 This release of e2fsprogs has support for file systems > 16TB. Online
2131 resize requires kernel support which will hopefully be in Linux
2132 version 3.2. Offline support is not yet available for > 16TB file
2133 systems, but will be coming.
2135 This release of e2fsprogs has support for clustered allocation. This
2136 reduces the number of block (now cluster) bitmaps by allocating and
2137 deallocating space in contiguous power-of-2 collections of blocks,
2138 which are called clustered. This is a file system level feature,
2139 called 'bigalloc', which must be enabled when the file system is
2140 initially formatted. It is not backwards compatible with older
2143 Added support for the Multi-Mount Protection (MMP) feature.
2145 E2fsck more efficiently uses scratch files for really big file
2146 systems. (This is a feature that has to be turned on explicitly; see
2147 [scratch_files] in the e2fsck.conf man page.)
2149 Fix a bug in e2fsck where if the free blocks and inodes counts are
2150 incorrect, e2fsck would fix them without printing an error message.
2151 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
2152 any explanation of what was fixed.
2154 E2fsck will no longer attempt to clone an extended attribute block in
2155 pass1b handling if the file system does not support extended
2158 E2fsck will be more careful accidentally asking the user to continue
2159 if the file system is mounted, so that an escape sequence won't cause
2160 a false positive. (Addresses Debian Bug: #619859)
2162 E2fsck now uses less cpu time in pass 5 when large portions of the
2163 bitmaps are uninitialized.
2165 E2fsck will no longer segfault when a corrupted file system has a bad
2166 extent, and removing it leads to a block needing to be deallocated.
2167 (Addresses SourceForge Bug: #2971800)
2169 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
2170 and print debugging information to make it easier to find potential
2173 E2fsck will check to see if the bad block inode looks insane, and will
2174 skip trying to use if it certain fields which should be zero look
2175 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
2176 to get confused and do more harm than good.
2178 If e2fsck modifies certain superblock fields which the kernel doesn't
2179 look at, it will now mark the superblock as dirty without marking the
2180 file system as changed. This avoids signaling the init scripts that
2181 a reboot is necessary, since the kernel isn't going to look at those
2182 fields, so it won't care if they have been changed.
2184 Fixed a bug in the libext2fs library (in the binary search routine of
2185 the icount abstraction) that could (very, very rarely) cause e2fsck to
2186 die in the middle of pass 1 or pass 2 processing.
2188 E2fsck will not try to do a discard operation if the -n option was
2189 specified on the command line.
2191 E2fsck now supports an extended "discard" option which will cause
2192 e2fsck to attempt discard all unused blocks after a full, successful
2195 E2fsck will check for the bad block inode to make sure it looks sane
2196 before trusting it, to avoid causing more harm than good to the file
2199 E2fsck now returns additional status bits in its exit code if it
2200 aborts early in the e2fsck run.
2202 E2fsck now correctly calculates the maximum file size in the case of
2203 the huge_file file system feature enabled without extents.
2205 The mke2fs and e2fsck programs now tries to use the punch hole command
2206 as a "discard" when operating on normal files.
2208 The e2image program now supports the qcow2 format, which is a more
2209 efficient way of capturing file system dumps.
2211 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
2212 per-device defaults to be specified in the configuration file.
2214 Mke2fs now supports the reserved_ratio relation in the [defaults] and
2215 [fs_types] section in mke2fs.conf.
2217 Mke2fs now creates extent-mapped directories for the root and
2218 lost+found directories.
2220 Mke2fs will skip zero'ing the journal if the extended option
2221 "lazy_journal_init" is specified. This can save a lot of time, but it
2222 does add a small amount of risk if the system crashes before the
2223 journal is overwritten entirely once. It is especially useful for
2226 Mke2fs will now create file systems that enable user namespace
2227 extended attributes and with time- and mount count-based file
2228 system checks disabled.
2230 Mke2fs will not set a stride or strip size of one block based on block
2231 device attributes obtained from sysfs.
2233 Mke2fs now displays a progress report during the discard process.
2235 Mke2fs now handles extreme file system parameters correctly which
2236 previously caused the inodes per group to drop below 8, leading to a
2237 segfault. (The inodes per group must be a multiple of 8, but the code
2238 didn't correctly deal with an inodes per group count less than 8.)
2240 Mke2fs and tune2fs previously would give an error if the user tried
2241 setting the stride and stripe-width parameters to zero; but this is
2242 necessary to disable the stride and stripe-width settings. So allow
2243 setting these superblock fields to zero. (Addresses Google Bug:
2246 Mke2fs now gives a warning if the auto-detected block size exceeds the
2249 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
2250 is the default), mke2fs will now set the s_max_mnt_count superblock
2251 field to -1, instead of 0. Kernels older then 3.0 will print a
2252 spurious message on each mount then they see a s_max_mnt_count set to
2253 0, which will annoy users. (Addresses Debian Bug: #632637)
2255 The default mke2fs.conf now has entries for "big" and "huge", which
2256 are needed for very big file systems.
2258 The resize2fs program now has support for a new online resize ioctl
2259 that can support file systems > 16TB, once it arrives in v3.x kernels.
2261 Fixed bug which caused resize2fs to fail when shrinking an empty file
2262 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
2264 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
2266 Allow tune2fs to remove external journals if the device can not be
2269 Debugfs's icheck will now correctly find inodes which use the
2270 searched-for block as an extended attribute block.
2272 Debugfs now has a new "punch" command which remove blocks from the
2275 Debugfs now has a new "e2freefrag" command which analyzes the free
2276 space fragmentation of the file system, using the same code as the
2279 Debugfs now has a "filefrag" command which displays information about
2280 a file's fragmentation.
2282 Add support to build a metadata-only, read-only, stripped-down version
2283 of debugfs called rdebugfs.
2285 Fixed a potential stack overrun bug in debugfs.
2287 The badblocks program now correctly recovers from I/O errors when
2288 direct I/O is being used. The badblocks command now also supports a
2289 -B option which forces the use of buffered I/O, and the -v option will
2290 provide a more detailed breakdown of read, write, and failed
2293 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
2295 Added support for journals larger than 2GB.
2297 Support using both hard links and symlinks when installing e2fsprogs.
2299 Add overflow checking to tune2fs -i's fsck interval, which must fit in
2302 The debugfs command now has a new 'blocks' command which prints out
2303 data blocks of a particular inode in a format which is useful for
2306 Filefrag will report 0 extents correctly in verbose mode. (Addresses
2307 RedHat Bugzilla: #653234)
2309 Filefrag has been fixed so its -v report prints the correct expected
2310 block number (previously there had been an off-by-one error). In
2311 addition, it will now display the number of contiguous extents when -v
2312 is not specified. This makes it consistent with the number of extents
2313 printed when the -v option was specified. In addition, the number of
2314 contiguous extents is far more interesting/useful than the number of
2315 physical extents for very large files. (Addresses Debian Bug:
2318 Logsave's usage message has been fixed. (Addresses Debian Bug:
2321 Avoid an infinite loop in ext2fs_find_block_device() if there are
2322 symlink loops in /dev caused by a buggy udev.
2324 Added a useful "fallocate" program to the contrib directory.
2326 Fixed an ABI compatibility problem in libext2fs which broke the dump
2327 program. Also added back some macros which dump needed so it could
2328 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
2331 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
2332 Debian Bug: #641667)
2334 Added internationalization support for libcom_err error table strings.
2336 Fixed various spelling mistakes found in various output strings found
2337 by I18N translators.
2339 Update translations: French, Chinese, Germany, Indonesian, Swedish,
2340 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
2343 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
2344 #614662, #632169, #641838, #627535, #629355)
2346 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
2352 Initial support for quota as an integrated feature, where the quota

2354 e2fsck is present, although disabled by default. It must be enabled
2355 by using the configure option --enable-quota.
2357 Reserved the on-disk fields for the metadata checksum and snapshot
2358 features, which are currently in development.
2360 The ext2fs library now has the new functions ext2fs_punch(),
2361 ext2fs_get_memzero() and ext2fs_file_get_inode().
2363 The ext2fs library now has support for calculating the crc32c checksum
2364 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
2366 The I/O manager now supports the discard operation.
2368 Reserved file system code points for new 1st class quota feature.
2370 Shortened the compilation lines by moving the autoconf defines to
2371 a config.h header file.
2373 Fixed a potential free of an uninitialized pointer in
2374 ext2fs_update_bb_inode().
2376 Fixed miscellaneous gcc -Wall and coverity warnings.
2378 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
2380 Fixed a build failure when OMIT_COM_ERR is defined.
2382 Improved error checking and fixed memory leaks caused by error return
2385 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
2386 the fsync() to be skipped.
2388 Added a test for extent-mapped journals by mke2fs and tune2fs.
2390 Added a test for creating a large (over 4GB) journal using mke2fs.
2392 Added a test to make sure the inode size remains constant.
2394 The regression test script now prints the list of which tests failed.
2396 The regression test system now uses /tmp for its scratch files, which
2397 is often a tmpfs mounted file system and hence much faster.
2399 The i_e2image test was fixed so it works with valgrind.
2401 Tests that rely on debugfs are now skipped if debugfs wasn't built.
2403 Fixed the dependencies for "make check" so all required dependencies
2404 are built before running the regression tests.
2406 A link to com_err.h is installed in $(includedir) during a "make install".
2408 The po/*.gmo files are automatically rebuilt if they are missing or
2409 out of date. This helps out Debian packaging.
2411 Allow ext2fs_get_memalign() to compile on systems that don't have
2414 Fixed a namespace leak in libext2fs (tdb_null).
2417 E2fsprogs 1.41.14 (December 22, 2010)
2418 =====================================
2420 Fix spurious complaint in mke2fs where it would complain if the file
2421 system type "default" is not defined in mke2fs.conf.
2423 The resize2fs program will no longer clear the resize_inode feature
2424 when the number reserved group descriptor blocks reaches zero. This
2425 allows for subsequent shrinks of the file system to work cleanly for
2426 flex_bg file systems.
2428 The resize2fs program now handles devices which are exactly 16T;
2429 previously it would give an error saying that the file system was too
2432 E2fsck (and the libext2fs library) will not use the extended rec_len
2433 encoding for file systems whose block size is less than 64k, for
2434 consistency with the kernel.
2439 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
2440 been fixed. (Addresses Sourceforge Bug: #3138115)
2442 The ext2fs_block_iterator2() function passed an incorrect ref_offset
2443 to its callback function in the case of sparse files. (Addresses

2446 Fix some type-punning warnings generated by newer versions of gcc.
2449 E2fsprogs 1.41.13 (December 13, 2010)
2450 =====================================
2452 E2fsck now supports the extended option "-E journal_only", which
2453 causes it to only do a journal replay. This is useful for scripts
2454 that want to first replay the journal and then check to see if it
2457 E2fsck will now support UUID= and LABEL= specifiers for the -j option
2458 (which specifies where to find the external journal). (Addresses
2461 E2fsck now has support for the problems/<problem code>/force_no
2462 configuration option in e2fsck.conf, which forces a problem to not be
2465 Dumpe2fs will now avoid printing large negative offsets for the bitmap
2466 blocks and instead print a message which is a bit more helpful for
2467 flex_bg file systems.
2469 Mke2fs will now check the file system type (specified with the -t
2470 option) to make sure it is defined in the mke2fs.conf file; if it is
2471 not, it will print an error and abort. If the usage type (specified
2472 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
2473 warning but will continue. (Addresses Debian Bug #594609)
2475 Clarified error message from resize2fs clarifying that on-line
2476 shrinking is not supported at all. (Addresses Debian Bug #599786)
2478 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
2479 displayed. (Addresses Debian Bug #555456)
2481 E2fsck will open the external journal in exclusive mode, to prevent
2482 the journal from getting truncated while it is in use due to a user
2483 accidentally trying to run e2fsck on a snapshotted file system volume.

2489 The tune2fs program can now set the uninit_bg feature without
2492 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
2493 default mount options settings which were added in 2.6.35.
2495 The e2fsck and dumpe2fs programs now support the new ext4 superblock
2496 fields which track where and when the first and most recent file
2497 system errors occurred. These fields are displayed by dumpe2fs and
2498 cleared by e2fsck. These new superblock fields were added in 2.6.36.
2500 Debugfs now uses a more concise format for listing extents in its
2501 stat command. This format also includes the interior extent tree
2502 blocks, which previously was missing from stat's output for
2505 Debugfs has a new option, -D, which will request Direct I/O access of
2508 Mke2fs will skip initializing the inode table if a device supports
2509 discard and the discard operation will result in zero'ed blocks.
2511 Badblocks will now correctly backspace over UTF-8 characters when
2512 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
2513 Debian Bugs #583782 and #587834)
2515 E2freefrag will now display the total number of free extents.
2517 Resize2fs -P no longer requires a freshly checked filesystem before
2518 printing the minimum resize size.
2520 Fixed a floating point precision error in a binary tree search routine
2521 that can lead to seg fault in e2fsck and resize2fs.
2523 Fixed a bug in e2fsck where if both the original and backup superblock
2524 are invalid in some way, e2fsck will fail going back to the original
2525 superblock because it didn't close the backup superblock first, and
2526 the exclusive open prevented the file system from being reopened.
2528 Fixed a big in e2freefrag which caused getopt parsing to fail on
2529 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
2531 Clarified an mke2fs error message so a missed common in an -E option
2532 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
2533 results in a more understandable explanation to the user.
2535 Mke2fs now displays the correct valid inode ratio range when
2536 complaining about an invalid inode ratio specified by the user.
2538 Mke2fs now understands the extended option "discard" and "nodiscard",
2539 and the older option -K is deprecated. The default of whether
2540 discards are enabled by default can be controlled by the mke2fs.conf
2543 Mke2fs's handling of logical and physical sector sizes has been
2544 improved to reflect the fact that there will be some SSD's with 8k and
2545 16k physical sectors arriving soon. Mke2fs will no longer force block
2546 size to be the physical sector size, since there will be devices where
2547 the physical sector size is larger than the system's page size, and
2548 hence larger than the maximal supported block size. In addition, if
2549 the minimal and optimal io size are not exported by the device, and
2550 the physical sector size is larger than the block size, the physical
2551 sector size will be used to set the Raid I/O optimization hints in the
2554 E2fsck will now display a better, more specific error message when the
2555 user enters a typo'ed device name, instead of blathering on about
2556 alternate superblocks.
2558 Fixed various Debian Packaging Issues
2560 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
2561 #589345, #591083; Addresses Launchpad Bug: #505719)
2563 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
2564 Polish, Swedish, and Vietnamese translations.
2570 Fix a dependency definition for the static and profiled blkid
2571 libraries which could cause compile failures in some configurations.
2572 (Addresses Debian Bug: #604629)
2574 Add support for Direct I/O in the Unix I/O access layer.
2576 Fixed a memory leak in the Unix I/O layer when changing block sizes.
2578 Fixed minor memory leaks in mke2fs.
2580 Added a new function to the ext2fs library, ext2fs_get_memalign().
2582 The tst_super_size test program will check to make sure the superblock
2583 fields are correctly aligned and will print them out so they can be
2584 manually checked for correctness.
2586 Fixed some makefile dependencies for test programs in lib/ext2fs.
2588 Reserved the feature flags and superblock fields needed for the Next3
2591 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
2592 EXT4_INCOMPAT_EA_INODE.
2595 E2fsprogs 1.41.12 (May 17, 2010)
2596 ================================
2598 Mke2fs now gives a correct error message if the external journal
2599 device is not found. (Addresses Red Hat Bug #572935)
2601 Resize2fs -P will now refuse to print a minimum size if the file
2602 system is not clean. Previously it would go ahead and print a minimum
2603 size anyway, which might not be correct, leading to user confusion.
2605 E2fsck now tests for extents that begin at physical block 0 and
2606 rejects them as invalid. (Addresses Google Bug: #2573806)
2608 Fixed a bug in e2fsck which could cause it to crash when trying to
2609 remove an invalid extent and the block bitmaps hadn't yet been loaded.
2610 (Addresses SourceForge Bug: #2971800)
2612 E2fsck now will completely skip time-based checks if the system clock
2613 looks insane or the option broken_system_clock is set in
2616 E2fsck would previously report an i_blocks corruption for a 4T file
2617 created using posix_fallocate; this bug has been fixed.
2619 E2fsck will now correctly mark a sparse journal as invalid and will
2620 delete and recreate the journal to address the problem.
2622 E2fsck would previously incorrectly ask the user whether she would
2623 like to abort the file system check after finding a problem --- and
2624 then abort regardless of the user's answer. This is annoying, and
2627 E2fsck can now continue even if it fails to recreate the resize
2628 inode; previously it would just abort the file system check
2631 E2fsck could potentially remove directory entries for inodes found in
2632 the unused region of the inode table; this would generally happen on
2633 ext4 file systems that do not use journalling. This bug has been fixed
2634 by not clearing these directory entries once it has been established
2635 that bg_unused_inodes may not be trustworthy; once pass #2 has been
2636 completed, e2fsck will restart the file system check from the
2637 beginning, and then it will be safe to delete any directory entries
2638 pointing to inodes that appear to be deleted. (Addresses Google Bug:
2641 E2fsck will not try to set the block group checksums if the user
2642 cancels the fsck with a control-C. It's a bad idea to set the
2643 checksums if e2fsck hasn't been completed, and it often results an the
2644 error message, "Inode bitmap not loaded while setting block group
2645 checksum info". (Addresses Launchpad Bug: #582035)
2647 The mke2fs program now queries the kernel for the physical as well as
2648 the logical sector size, and will not allow a blocksize below the
2649 logical, and will strongly encourage a blocksize at least as big as
2650 the physical blocksize. This is needed for 4k sector drives that
2651 emulate 512 byte sector sizes.
2653 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
2654 rarely needed, but it is a legal value.
2656 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
2657 not needed, and offer to clear it; this is a sign of a kernel bug, but
2658 more importantly, some released kernels may crash when this situation
2659 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
2661 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
2662 i_size is correct. (Kernels starting with 2.6.34 will set
2665 The com_err library will now only output ^M (a CR character) when the
2668 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
2669 and Vietnamese translations.
2671 Fixed various Debian packaging issues --- see debian/changelog for
2672 details. (Addresses Debian Bugs: #571247, #563487)
2678 The regression test suite now uses its own mke2fs.conf file, so that
2679 downstream distributions want change the mke2fs.conf file which is
2680 distributed in the RPM or dpkg file, without worrying about screwing
2681 up the regression test results.
2683 Always build namei.o so that building with configure --disable-debugfs
2684 works correctly. Long-term, if we care about reduced e2fsprogs
2685 builds, we need a more general solution for deciding what .o files are
2686 needed for a particular build. Given that install floppies are going
2687 (gone?) the way the dodo bird, we probably don't care, though.
2688 (Addresses Sourceforge Bug: #2911433)
2690 Add configure options --enable-symlink-build and
2691 --enable-symlink-install, which allow e2fsprogs be built using
2692 symlinks instead of hard links, and to be installed using symlinks
2693 instead of hard links, respectively. It is useful when the file
2694 system where the build is taking place, or the file system where
2695 e2fsprogs is installed, can't handle hard links for some reason.
2696 (Addresses Sourceforge Bug: #1436294)
2698 Fixed compile warning in mke2fs.c.
2701 E2fsprogs 1.41.11 (March 14, 2010)
2702 ==================================
2704 E2fsck will no longer give a fatal error and abort if the physical
2705 device has been resized beyond 2**32 blocks. (Addresses Launchpad
2708 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
2709 the allocation status of the block <blk>. (Addresses Debian Bug:
2712 E2fsck now prints a much more emphatic and hopefully scary message
2713 when a file system is detected as mounted while doing a read/write
2714 check of the filesystem. Hopefully this will dissuade users from
2715 thinking, "surely that message doesn't apply to *me*" :-(
2717 E2fsck -n will now always open the file system read-only. We now
2718 disallow certain combination of options which previously were manual
2719 exceptions; this is bad because it causes users to think they are
2720 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
2721 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
2723 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
2724 it detected a badly aligned partition. Unfortunately, this broke some
2725 distribution installation scripts, so it now just prints the warning
2726 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
2727 Launchpad Bug: #530071)
2729 Mke2fs would take a long time to create very large journal files for
2730 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
2733 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
2734 2.6.34 kernels to make e2fsck not complain about blocks deliberately
2735 fallocated() beyond an inode's i_size.
2737 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
2738 e2fsck -fD can corrupt non-indexed directories when are exists one or
2739 more file names which alphabetically sort before ".". This can happen
2740 with ext2 filesystems or for small directories (take less than a lock)
2741 which contain filenames that begin with a space or some other
2742 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
2749 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

2762 Add libss support for libreadline.so.6.
2764 Fix e2fsck's check for extent-mapped directory with an incorrect file
2767 Add new e2fsck.conf configuration option, default/broken_system_clock
2768 to support systems with broken CMOS hardware clocks. Also, since too
2769 many distributions seem to have broken virtualization scripts now,
2770 e2fsck will by default accept dates which are off by up to 24 hours by
2771 default. (Addresses Debian Bugs: #559776, #557636)
2773 Fix a bug where mke2fs may not use the best placement of the inode
2774 table when there is only room for a single block group in the last
2777 E2fsck is now smarter when it needs to allocate blocks in the course
2778 of fixing file system problems. This reduces the number of spurious
2779 differences found in pass #5.
2781 E2fsck will no longer rehash directories which fit in a single
2784 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
2785 sparse directories which use extents).
2787 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
2789 Fix a bug in filefrag where on platforms which can allow file systems
2790 with 8k blocks, that it doesn't core dump when it sees a file system
2791 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
2794 E2fsck will correctly fix directories that are have an inaccurate
2795 i_size as well as other problems in a single pass, instead of
2796 requiring two e2fsck runs before the file system is fully fixed.
2798 Fix e2fsck so it will correctly find and detect duplicate directory
2799 entries for non-indexed directories. ( Addresses Sourceforge Bug:
2802 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or

2828 have the HUGE_FILE_FL flag set.
2830 Fix e2fsck's handling of 64-bit i_blocks fields.
2832 E2fsck will now print "Illegal indirect block", "Illegal
2833 double-indirect block", etc., instead of "Illegal block #-1" or
2834 "Illegal block #-2", etc. This makes it easier for users to
2835 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
2837 Mke2fs now will obtain get device topology information from blkid and
2838 use it to populate the superblock stride and stripe sizes. It will

2892 E2fsprogs 1.41.9 (August 22, 2009)
2893 ==================================
2895 Fix a bug in e2fsck routines for reallocating an inode table which
2896 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
2897 filesystem feature with a relatively rare (and specific) filesystem
2898 corruption. This fix causes e2fsck to try to find space for a new
2899 portion of the inode table in the containing flex_bg, and if that
2900 fails, the new portion of the inode table will be allocated in any
2901 free space available in the filesystem.
2903 Make e2fsck less annoying by only asking for permission to relocate a
2904 block group's inode table once, instead of for every overlapping
2905 block. Similarly, only ask once to recompute the block group
2906 checksums, instead of once for each corrupted block group's checksum.
2908 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
2909 not present, and it needs to fall back to using the FIBMAP ioctl.
2911 Fix filefrag to correctly print the number of extents for zero-length
2912 files. (Addresses Debian Bug: #540376)
2914 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
2915 to more easily debug the FIBMAP code.
2917 Fixed filefrag for non-extent based files.
2919 Add a new program, e2freefrag, which displays information about the
2920 free space fragmentation in an ext2/3/4 filesystem.
2922 Fix inode resizing via tune2fs -I so that it works correctly in the
2923 face of non-empty bad blocks inodes, and if the filesystem was
2924 formatted using the "mke2fs -E stride=N" option for RAID arrays.
2926 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
2927 and corrupt large directories if the directory needs to shrink by more
2928 than one block. (Addresses Debian Bug: #537510)
2930 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
2931 last mount times are in the future, they are corrected even if
2932 buggy_init_scripts is set. This is needed because otherwise resize2fs
2933 will refuse to resize the filesystem, even after running "e2fsck -f".
2934 (Addresses Launchpad bug: #373409)
2936 E2fsck will now print much fuller information when the last mount time
2937 or last written time is in the future, since most people can't seem to

2939 failed CMOS/RTS clock battery.

2964 there aren't any free blocks or inodes in the already-used block
2967 Improve ext2fs_extent_set_bmap() to avoid creating new extents which

3033 uninitialized data into the portion of the inode beyond the first 128
3034 bytes when operating on inodes mapped via extents; potentially
3035 corrupting filesystems.

3089 E2fsprogs 1.41.6 (May 30, 2009)
3090 ===============================
3092 Fix a critical regression in e2fsck introduced version 1.41.5 which
3093 can undo updates to the block group descriptors after a journal replay.
3095 If e2fsck receives an I/O error while replaying the journal, prompt
3096 the user whether they want to ignore the error or not; if e2fsck is
3097 run in preen mode, force fsck to abort the preen pass.
3099 Fix a bug which would cause e2fsck to core dump if the filesystem
3100 contains a corrupt extent header, and the user declines to clear the
3101 inode. (Addresses Sourceforge Bug: #2791794)
3103 Fix e2fsck to restart only once in the case of multiple block groups
3104 which inodes in use that are in the uninitialized part of the block
3105 group's inode table.
3107 To reduce user confusion, if the /etc/mtab file is missing
3108 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
3109 new, explicit error code to indicate this case. This will cause
3110 e2fsck to give a clearer error message when the user is using buggy
3111 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
3114 Fix e2fsck so that if the primary group descriptors are corrupted, but
3115 the backup superblock is entirely invalid, to go back to using (and
3116 fixing) the primary group descriptors instead of completely giving up
3117 on the filesystem. (Addresses Debian Bug: #516820)
3119 Change e2fsck to not abort a preen pass if an inode is found to have
3120 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
3121 kernels (post 2.6.29) will ignore this field. So let's fix it
3122 automatically during the preen pass instead of forcing the user to fix
3123 this up manually. (Addresses Debian Bug: #526524)
3125 Add resource tracking for e2fsck passes 1b through 1d.
3127 Speed up e2fsck by eliminating unnecessary journal checks if the
3128 filesystem is already mounted and doesn't need recovery (since the
3129 kernel would have run the journal when the filesystem was mounted.)
3130 Also speed up e2fsck by avoiding unnecessary block group descriptor
3131 updates in ext2fs_close().
3133 Add support to chattr to migrate inodes from using direct/indirect
3136 Avoid corrupting the filesystem if there is an attempt to shrink a
3137 filesystem using resize2fs smaller than possible by making
3138 ext2fs_set_bmap() more careful not to delete the old block until the
3139 new block can be inserted. In addition, fix a bug in how the minimum
3140 size of the filesystem (plus a safety margin) is calculated, and
3141 modify resize2fs to refuse to shrink the filesystem below that minimum
3142 size without the force flag.
3144 Teach blkid to try to figure out DM device names using take advantage
3145 of information in sysfs when running on kernels (2.6.29 and later)
3146 which provide this information in /sys/block/dm-<N>/dm/name; this is
3147 much faster than scanning for the device number in /dev/mapper.
3149 Fix blkid to prefer /dev/mapper/<name> device names instead of the
3150 private /dev/dm-X names.
3152 Add an -a option to debugfs's close_filesys command which writes any
3153 changes to the superblock or block group descriptors to all of the
3154 backup superblock locations.
3156 Add support to the filefrag program to use the FIEMAP ioctl.
3158 Update Chinese translation from the Translation Project.
3160 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
3161 Launchpad Bug: #381854)
3163 Fixed various Debian packaging issues --- see debian/changelog for
3164 details. (Addresses Debian Bug #506064)
3170 Add test code to make sure e2fsck's problem.c doesn't have two problem
3171 codes assigned to duplicate values.
3173 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
3174 (Addresses Sourceforge Bug: #2780205)
3176 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
3177 function declaration for init_resource_track() and
3178 print_resource_track() when RESOURCE_TRACK is not defined.
3180 The test code which is used to build the tst_csum program has been
3181 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
3182 avoid compile problems caused by not having a prototype for
3183 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
3185 Update the config.guess and config.sub file to the latest from the
3186 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
3187 Debian Bug: #528330)
3189 Add a new function, ext2fs_extent_open2(), which behaves like
3190 pext2fs_extent_open(), but uses the user-supplied inode structure
3191 when opening an extent instead of reading the inode from disk.
3194 E2fsprogs 1.41.5 (April 23, 2009)
3195 =================================
3197 Fix a number of filesystem corruption bugs in resize2fs when growing
3198 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
3201 Debugfs can now set i_file_acl_high via the set_inodes_field command,
3202 and print a 64-bit file acl. This is useful for debugging filesystem
3203 corruptions where the high bits of i_file_acl_high are set. E2fsck
3204 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
3205 since some Linux kernel versions pay attention to this field even when
3208 Speed up e2fsck when checking clean filesystems by avoiding
3209 unnecessary block reads, and coalescing the block group descriptor
3210 blocks so they are read using a single read operation.
3212 The libuuid library will now close all file descriptors before running
3213 uuidd. This avoids problems when the calling program has open sockets
3214 which then never get closed because uuidd is a long-running helper
3215 daemon. (Addresses Launchpad bug: #305057)
3217 In order to avoid unnecessary full filesystem checks by e2fsck after
3218 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
3219 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
3221 Mke2fs will avoid trying to create the journal when run in
3222 superblock-only mode (mke2fs -S), since the left-over journal in the
3223 inode table will cause mke2fs to fail.
3225 Fix a bug in libext2fs functions that check to see if a particular
3226 device or filesystem image is mounted, which would cause these
3227 functions to report that a file identical to the (relative) pathname
3228 used by a pseudo-filesystem was mounted when in fact it was not.
3230 Update Czech translation from the Translation Project.
3232 Add Chinese (simplified) translation from the Translation Project.
3234 Fix support for external journals (which was broken in e2fsprogs
3237 Fix a regression in debugfs where the "stat" command when no
3238 filesystem was open would cause debugfs to crash with a segmentation
3241 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
3242 used to support filesystems without a journal. Update the blkid
3243 library so it understands this.
3245 The blkid library will remove an entry from the blkid cache
3246 representing the entire disk if partitions are found, since presumably
3247 the device previously had no partition table, but has now transitioned
3248 to using a partition table.
3250 Add a check to mke2fs and tune2fs that the argument to the -m option
3251 (which specifies the reserved ratio) must be greater than zero.
3252 (Addresses Debian Bug: #517015)
3254 Add support for tracking the number kilobytes written to the
3255 filesystem via the superblock field s_kbytes_written. It will be
3256 updated by the kernel as well as by e2fsprogs programs which write to
3257 the filesystem. This is useful for tracking the wear to filesystems
3258 on Solid State Drives.
3260 Fix compatibility issue in the libext2fs info file and makeinfo
3261 version 4.12. (Addresses Red Hat Bugzilla: #481620)
3263 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
3265 Fixed various Debian packaging issues --- see debian/changelog for
3266 details. (Addresses Debian Bug: #506279)
3271 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
3274 Fix various gcc compilation warnings and other programming cleanups.
3275 (Addresses Red Hat Bugzilla: #486997)
3277 Add support for building the blkid command statically.
3279 Add support for disabling the built-in blkid library in favor of a
3280 system-installed blkid implementation via the configure option
3284 E2fsprogs 1.41.4 (January 27, 2009)
3285 ===================================
3287 Fixed a bug which could sometimes cause blkid to return an exit value
3288 of zero for a non-existent device (Addresses Debian Bug: #502541)
3290 Blkid will now recognize ext3 filesystems that have the test_fs flag
3291 set as ext3 filesystems.
3293 The blkid library will now recognize btrfs filesystems and swap
3294 devices currently used by user-level software suspend.
3296 Tune2fs now updates the block group checksums when changing the UUID
3297 to avoid causing e2fsck to complain vociferously at the next reboot.
3299 Tune2fs's inode size resizing algorithms have been fixed so it is not
3300 vastly inefficient for moderate-to-large filesystems, due to some
3301 O(n**2) and O(n*m) algorithms that didn't scale well at all.
3303 Fix tune2fs's inode resizing algorithm so it will not corrupt
3304 filesystems laid out for RAID filesystems; in addition, tune2fs will
3305 refuse to change the inode size for filesystems that have the flex_bg
3306 feature enabled. (This is a limitation in the current implementation
3309 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
3310 filesystems with 32-bit block numbers, when the headers for 64-bit
3311 block numbers was added. This regression has been fixed.
3313 Debugfs's ncheck command has been fixed to avoid printing garbage
3314 characters at the end of file names.
3316 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
3317 when shrinking filesystems with uninit_bg feature would not be moved.
3318 In addition, blocks and inode table blocks were not being correctly
3319 freed when shrinking filesystems with the flex_bg feable, which caused
3320 resize2fs -M to fail. Finally, when blocks are moved, make sure the
3321 uninitialized flag in extents is preserved.
3323 Fix bug which caused dumpe2fs to abort with an error if run on a
3324 filesystem that contained an external journal.
3326 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
3327 for this in argv[0] to provide better legacy support for these
3328 distributions. This is a practice that should NOT be continued,
3331 Mke2fs now has a new option -U, which allows the user to specify the
3332 UUID that should be used for the new filesystem.
3334 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
3335 minus one block. This allows users who have read that ext3 supports
3336 up to 16TB filesystems and who create a 16TB LVM to not get confused,
3337 since the true limit is really 16TB minus one block.
3339 E2fsck will no longer abort an fsck run if block group has an errant
3342 E2fsck now distinguishes between fragmented directories and fragmented
3343 files in verbose mode statistics and in the fragcheck report.
3345 Fix a bug in e2fsck which caused it double count non-contiguous
3346 extent-based inodes.
3348 E2fsck will leave some slack space when repacking directories to allow
3349 room for a few directory entries to be added without causing leaf
3350 nodes to be split right away.
3352 Fix a bug which caused e2fsck to crash when it comes across a
3353 corrupted interior node in an extent tree with the error message:
3354 "Error1: Corrupt extent header on inode XXXXXX"
3356 E2fsck problem descriptions involving the journal are no longer
3357 referred to as "ext3" problems, since ext4 filesystems also have
3360 Fix a long-standing bug in e2fsck which would cause it to crash when
3361 replying journals for filesystems with block sizes greater than 8k.
3363 Update Catalan translation from the Translation Project.
3365 Fixed various Debian packaging issues --- see debian/changelog for
3366 details. (Addresses Debian Bugs: #503057, #502323, #511207)
3371 Fix build of e2fsck.profiled, and add support for building profiled
3372 binaries in the misc directory if configured with --enable-profile.
3374 The ext2fs_open() function now performs more sanity checks on the
3375 superblock to avoid potential divide by zero errors by other parts of
3378 The ext2fs_read_inode_full() function now has a safety check to avoid
3379 a segmentation fault on corrupted filesystems.
3381 The ext2fs_new_inode() function now has a sanity check so that if the
3382 s_first_inode field in the superblock is insane, it will return
3383 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
3385 To avoid segmentation faults, ext2fs_block_alloc_stats() and
3386 ext2fs_inode_alloc_stats() now validates the passed inode or block
3387 number to avoid overrunning an array boundary.
3389 Various signed/unsigned errors for variables containing block numbers
3392 Accommodations for gcc's stupidity in not realizing that constant
3393 strings that do not contain a '%' character are safe to use in format
3394 strings have been made so that distributions that want to compile
3395 e2fsprogs with -Werror=format-security have an easier time doing so.
3397 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
3399 Added the utility make-sparse.c to the contrib directory.
3401 The ext2fs_block_iterate2() function now reflects errors from
3402 ext2fs_extent_set_bmap() to the caller, if the callback tries to
3403 change a block on an extent-based file, and ext2fs_extent_set_bmap()
3404 fails for some reason (for example, there isn't enough disk space to
3405 split a node and expand the extent tree.
3407 The ext2fs_block_iterate2() function will preserve the uninit flag in
3408 extents when the callback function modifies a block in an extent-based
3411 E2fsck will now flag filesystems that have an insane s_first_ino field
3412 in their superblock, and attempt to use a backup superblock to repair
3416 E2fsprogs 1.41.3 (October 12, 2008)
3417 ===================================
3419 E2fsck has been fixed so it prints the correct inode number for
3420 uinit_bg related problems.
3422 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
3423 is available on linux. This can be disabled via a configuration
3424 option in /etc/e2fsck.conf.
3426 Fix a file descriptor leak in libblkid when checking to see if an ext4
3427 or ext4dev module exists.
3429 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
3430 while trying to close a filesystem can lead to infinite loops.
3431 (Addresses Red Hat Bugzilla #465679)
3433 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
3434 will cause resize2fs to drop into an infinite loop. (Addresses Red
3435 Hat Bugzilla: #465984)
3437 Add a check in the Unix I/O functions in libext2fs so that when a
3438 device is opened read/write, return an error if the device is
3439 read-only using the BLKROGET ioctl.
3441 Fix debugfs's ncheck command so that it prints all of the names of
3442 hardlinks in the same directory.
3444 Fix a bug in libblkid so it correctly detects whether the ext4 and
3445 ext4dev filesystems are available, so that the ext4dev->ext4
3446 fallback code works correctly.
3451 Fix a parallel build problem by making sure util/subst is built before
3452 trying to build the lib/et directory. (Addresses Sourceforge Bug:
3455 Updated "make depend" information for crc16.o
3458 E2fsprogs 1.41.2 (October 2, 2008)
3459 ==================================
3461 Fix e2fsck's automatic blocksize detection. This fixes a regression
3462 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
3463 specifies a block number using the -b option if the blocksize option
3464 isn't also specified using -B. Unfortunately, users very commonly
3465 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
3466 superblock; in fact e2fsck will often suggest this kind of command
3469 Enhance the debugfs's "ncheck" command so it will print all of the
3470 pathnames for the specified inodes. (Previously, in some cases ncheck
3471 might not print a pathname for an inode at all if some of the other
3472 inodes had multiple hard links.)
3474 Enhance debugfs's "hash" command so the hash seed can be specified via
3475 a command-line option. In addition, allow the hash algorithm to be
3476 specified by name instead of just by number.
3478 Fix e2fsck so that we don't accidentally print the translation file's
3479 header when asking the user a custom question so there is no prompt
3480 defined for a particular problem record. For example, the question
3481 "Run journal anyway" will get the PO header tacked on because e2fsck
3482 erroneously passed the null string to _(). (Addresses Launchpad Bug:

3516 Fix a potential file descriptor leak in libcom_err by setting the
3517 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
3520 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
3521 has been carrying a patch for a long time to prevent a largely
3522 theoretical race condition if a multi-threaded application adds and
3523 removes error tables in multiple threads. Unfortunately SuSE's
3524 approach breaks compatibility by forcing applications to link and
3525 compile with the -pthread option; using pthread mutexes has
3526 historically been problematic. We fix this by using sem_post/sem_init

3536 have the e2fsprogs shared libraries already installed. (Addresses
3537 Sourceforge Bug: #2088537)
3539 Fix the pkg-config files so they work correctly when linking with

3542 instead. (Addresses Sourceforge Bug: #2089537)
3544 Make sure ext2fs_swab64() is compiled for all platforms, and not just
3545 for x86. (Addresses Debian Bug: #497515)
3547 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
3548 non-x86 platforms. (They had been removed for x86 earlier.)
3550 Fix diet libc compilation support, which had bitrotted due to lack of
3551 TLC. Fixing this improves general portability.

3560 gen-tarball print the size of the resulting tar.gz file.
3563 E2fsprogs 1.41.1 (September 1, 2008)
3564 ====================================
3566 Many people are forgetting to update their mke2fs.conf file, and this
3567 causes ext3, ext4, and ext4dev filesystems won't get created with the
3568 proper features enabled. We address this in two ways. First, mke2fs
3569 will issue a warning if there is not definition for an ext3, ext4, or
3570 ext4dev filesystem and the user is trying to create such a filesystem
3571 type. Secondly, when installing from a source build, "make install"
3572 will provide basic configuration file handling for /etc/mke2fs.conf.
3573 If it exists, and does not mention ext4dev, it will be moved aside to
3574 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
3575 be installed. If the existing /etc/mke2fs.conf file does mention
3576 ext4dev, then "make install" will install official mke2fs.conf file as
3577 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
3578 they should look to see if any changes need to be merged.
3580 The mke2fs program will now create the journal in the middle of the
3581 filesystem, since this minimizes seek times on average for fsync-heavy
3582 workloads. In addition, mke2fs will now create journals using extents
3583 for filesystems that support them. This results in a more efficient
3584 encoding for the journal since it eliminates the need for using
3587 The mke2fs program will avoid allocating an extra block to the
3588 journal. (Addresses Sourceforge Bug: #1483791)
3590 Mke2fs will correctly enforce the prohibition against features
3591 (specifically read-only features) in revision 0 filesystems. (Thanks
3592 to Benno Schulenberg for noticing this problem.)
3594 Mke2fs previously would occasionally create some slightly non-optimally
3595 placed inode tables; this bug has been fixed.
3597 The mke2fs and tune2fs programs now print the correct usage message
3598 describing the maximum journal size. (Addresses Debian Bug: #491620)
3600 Add support for setting the default hash algorithm used in b-tree
3601 directories in tune2fs (from a command-line option) or mke2fs (via
3602 mke2fs.conf). In addition, change the default hash algorithm to
3603 half_md4, since it is faster and better.
3605 The blkid library will now recognize MacOS hfsx filesystems, and
3606 correctly extract the label and uuid for hfs, hfsx, and hfsplus
3607 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
3609 The blkid library has improved detection of JFS and HPFS filesystems.
3610 (Addresses Launchpad Bug: #255255)
3612 The blkid library is now much more efficiently handling devicemapper
3613 devices, mainly by no longer using the devicemapper library. This can
3614 speed up access for systems with a large number of device mapper
3617 Blkid had a number of cache validation bugs in libblkid that have been
3618 fixed. (Addresses Debian Bug: #493216)
3620 Resize2fs will now properly close out the "updating inode references"
3621 progress bar so there is a newline printed before printing the final
3622 "resize is successful" message.
3624 Resize2fs will now correctly handle filesystems with extents and/o
3625 uninitialized block groups correctly when file/directory blocks need
3626 to relocated (i.e., when shrinking a filesystem or if the resize_inode
3627 is not present). To support this, the ext2fs library now supports
3628 initializing inode and block bitmaps that are not yet initialized when
3629 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
3630 addition, e2fs_block_iterate2() can now support changing the location
3631 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
3632 been optimized to avoid creating unnecessary new extents when updating
3633 the location of blocks in the extent tree. This will also help out
3634 e2fsck's recovery of obscurely corrupted filesystems with extents,
3635 when blocks are claimed by multiple inodes.
3637 Add support for on-line resizing ext4 filesystem with the flex_bg
3638 filesystem feature. The method for doing so is not optimal, but to do
3639 a better job will require kernel support.
3641 E2fsprogs 1.41.0 introduced a bug in libext2fs which caused e2image and
3642 debugfs programs to not be able to read e2image files; the signed
3643 vs. unsigned bug in the code which read bitmaps from the e2image has
3644 been fixed. (Addresses Debian Bug: #495830)
3646 Resize2fs is now correctly managing the directory in-use counts when
3647 shrinking filesystems and directory inodes needed to be moved from one
3648 block group to another. This bug has been around since e2fsprogs
3649 1.26, and is largely harmless, but does cause a filesystem corruption
3650 which will be flagged by e2fsck after the filesystem has been shrunk.
3652 E2fsck will no longer issue spurious complaints about the inode size
3653 caused by very large extent-based files, and by blocks reallocated
3654 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
3655 Kernel Bugzilla: #11341)
3657 Mke2fs will now set the creation timestamp on the lost+found directory
3658 and the root directory. (More generally, all new inodes created using
3659 the ext2fs library will correctly set the creation timestamp.)
3661 E2fsck now correctly calculates ind/dind/tind statistics in the
3662 presence of extent-based files. In addition, "e2fsck -v" will report
3663 statistics of the depth of extent trees in the filesystem. E2fsck can
3664 also give an inode fragmentation report using "e2fsck -E fragcheck"
3665 which can be useful when debugging the kernel block allocation
3668 Fix support for empty directory blocks in ext4 filesystems with 64k
3669 blocksize filesystems.
3671 E2fsck will now print the depth of corrupt htree directories.
3673 Debugfs's htree command now correctly understands extent-based
3674 directories. It will also print out the minor hash as well as the
3677 Debugfs has a new command which will print the supported features of
3678 e2fsprogs, to enable scripts to know whether the installed version of
3679 e2fsprogs can support a specific feature.
3681 Debugfs will now write files using extents for filesystems that
3684 The error message printed by "tune2fs -I" if the inode size was too
3685 small was rather confusing, so it has been improved. Also, we won't
3686 try to create an undo log until we know that command-line-specified
3687 parameters such as "tune2fs -I <inode size>" are valid.
3689 Given some filesystems found "in the wild" that had non-zero block
3690 group checksums even though the uninit_bg/gdt_sum feature was not
3691 enabled, e2fsck would issue spurious error messages. Teach
3692 ext2fs_group_desc_csum_verify() to ignore the block group checksum
3693 entirely if the feature flag is not set. (Addresses Debian Bug:
3696 The blkid program will now print out a user-friendly listing of all of
3697 the block devices in the system and what they contain when given the
3698 -L option. (Addresses Debian Bug: #490527)
3700 The filefrag program now has a more accurate calculation for the
3701 number of ideal extents. (Addresses Debian Bug: #458306)
3703 The test I/O manager is now enabled by default, but its overhead is
3704 only incurred when it would be enabled via the TEST_IO_FLAGS or
3705 TEST_IO_BLOCK environment variables.
3707 Typographical errors in various program strings and usage messages
3708 have been fixed; most of these were pointed out by the e2fsprogs
3709 message catalog translators. (Thanks, translators!)
3711 Update and clarified various man pages, as well as some typographical
3712 errors in the libext2fs texinfo file.
3714 Fixed various Debian packaging issues --- see debian/changelog for
3717 Add Indonesian and update French, Polish, Dutch, German, Swedish,
3718 Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
3724 Fix portability problem with the badblocks group; for systems that
3725 don't have nanosleep(), try using usleep() instead.
3727 The "make check" target in the e2fsck directory now sets
3728 LD_LIBRARY_PATH before running the various e2fsck internal library
3731 The crc32 regression test in the e2fsck library is now portable to
3732 greater variety of environments, including big-endian systems and
3733 when cross-building e2fsprogs for embedded systems. (Addresses
3734 Sourceforge Bug: #2019287)
3736 The ext2fs_extent_set_bmap() had some bugs when setting the first
3737 block in a file, or when replacing a single block extent. Those cases
3738 fortunately were came up relatively rarely when e2fsck was checking
3739 files, but caused some problems when resize2fs was shrinking
3742 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
3745 Various ext2fs library functions --- ext2fs_block_iterate2(),
3746 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
3747 allocated memory to avoid memory leaks in all of their error return
3750 Ext2ed was failing to build because masix support had been removed in
3751 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
3753 The configure script now respects the LDFLAGS environment variable if
3754 it is set when configure is called. (Addresses Sourceforge Feature
3757 Libuuid is now more portable to the Windows platform. (Addresses
3758 Sourceforge Feature Request: #1937287)
3760 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
3761 bare echo commands so that configure flags such as --quiet work
3762 correctly. (Addresses Sourceforge Patches: #2058794)
3764 A few uses of sprintf have been removed from the ext2fs library to
3765 make life easier for bootloaders with a limited libc environment.
3766 (Addresses Sourceforge Bug: #2049120)
3768 The ext2fs_read_inode() checks the validity of the inode number passed
3769 to it earlier, to avoid doing some needless work when it would fail
3772 The ext2fs_open() checks the validity of the blocksize parameter
3773 passed to it earlier, to avoid doing some needless work when it would
3776 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
3777 top-level Makefile. That automatic rule is used to better support
3778 SCCS, but it caused problems for a particular niche distribution which
3779 likes to use configure.sh files to store the configure options used to
3780 build a package. Unfortunately GNU make will use the configure.sh to
3781 replace the configure script, resulting in a self-inflicted fork bomb
3782 leading to an out-of-memory crash.
3784 To support old GNU C compilers don't use C99/C++ comments, but only
3785 K&R style comments, and don't try to use __builtin_expect if __GNUC__
3786 is less than 3. (__builtin_expect is only supported for gcc versions
3787 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
3788 this is an optimization, we only try to use __builtin_expect for gcc 3
3791 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
3792 __LITTLE_ENDIAN, which are only defined by glibc's header files and
3793 hence isn't portable.
3795 For the convenience for some distributions that need a static tune2fs,
3796 the Makefile for misc/ now has a tune2fs.static target.
3798 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
3799 for extent-based files
3801 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
3804 All source files no longer have any trailing white space.
3806 The io_channel_read_blk64() and io_channel_write_blk64() functions are
3807 now functions instead of C preprocessor macros to provide better
3808 forward compatibility.
3810 The e2fpsrogs translation template now expands the @x abbreviation.
3812 Various namespace leakages in libblkid, libe2p, and libext2fs have
3815 Fix a parallel build problem in e2fsprogs.
3817 E2fsprogs is now more portable to Solaris.
3818 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
3820 * Scripts do not assume that /bin/true is always in /bin
3821 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
3822 * Flush stdio handles before calling setbuf(), since Solaris will
3823 discard any pending output to the stream.
3824 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
3825 picky about which C compiler can be used for SUSv3 conformance.
3826 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
3827 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
3828 Since we need some SUSv3 functions, consistently use SUSv3 so
3829 that e2fsprogs will build on Solaris using c99.
3830 * Solaris C99 does not support varargs C preprocessor macros
3831 * Solaris header files pollute the C namespace if in/netinet.h
3832 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
3834 * Solaris ships with a pathetically ancient shell in /bin/sh so we
3835 avoid the use of various more advanced shell constructs such as $().
3837 The "make rpm" command will now take some extra configure options from
3838 the build environment without needing to patch the source tree.
3840 The ext2fs_add_dir_block() function will now grow the dblist more
3841 aggressively as an optimization to avoid copying the array too often.
3843 The e2fsck_write_bitmaps() will write the block and inode bitmaps
3844 together instead of in two passes.
3847 E2fsprogs 1.41 (July 10, 2008)
3848 ==============================
3850 Add support for ext4 filesystem features, in particular extents,
3851 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
3852 support for checking journal checksums. Debugfs will print new
3853 superblock and inode fields that were defined for ext4. For example,
3854 the nanosecond and i_version fields of an inode, and the
3855 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
3856 Note: Resize2fs doesn't currently support the combination of flex_bg
3857 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
3859 Tune2fs can support migrating a filesystem from using 128 byte inodes
3860 to 256 byte inodes, so it can take advantage of the full features of
3863 Add support for "undo" support. E2fsck and mke2fs can optionally
3864 record an undo log which can replayed by the program e2undo.
3866 E2fsck could damage a filesystem by trying to relocate inode tables
3867 due to corrupted block group descriptors, where the attempted inode
3868 table relocation would do far more harm than good. E2fsck has been
3869 fixed to detect this these sorts of corrupted block group descriptors
3870 much earlier in e2fsck processing, so it can try to use the backup
3871 superblock and block group descriptors first. This should be a much
3872 better strategy for recovering these types of corrupted filesystems.
3873 (Addresses Sourceforge Bug: #1840291)
3875 E2fsck will display a more understandable message when the last check
3876 field in the superblock is in the future. (Addresses Debian Bug:
3879 E2fsck now performs more extensive and careful checks of extended
3880 attributes stored in the inode.
3882 Enhance mke2fs to print a more explanatory error message when
3883 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
3886 Fix mke2fs to use a default block size of 4k when formatting an
3887 external journal device. This is done by using a fixed filesystem
3888 type list that consists only of the single filesystem type "journal"
3889 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
3890 Debian Bug: #488663)
3892 Speed up how mke2fs writes the journal data blocks by writing the disk
3893 blocks in larger chunks.
3895 Fix blkid handling of stale devices. Fix a bug which could cause a
3896 core dump while garbage collecting the blkid cache, and assure that
3897 blkid_find_dev_with_tag() never returns a non-existent device. Also,
3898 if a filesystem is found at a new /dev location, eliminate any
3899 duplicate stale entries which can not be verified.
3900 (Addresses Debian Bugs: #487758, #487783)
3902 Add more paranoid checks for LVM volumes and swap partitions in
3903 blkid's probe function, to reduce the chances of false positives.
3905 The mke2fs program now has a much more sophisticated system for
3906 controlling configuration parameters of a newly created filesystem
3907 based on a split filesystem and usage type system. The -t option to
3908 mke2fs was a deprecated alias to -c; it now specifies a filesystem
3909 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
3910 separated usage list. The filesystem type information and type
3911 information is used to extract configuration parameters from the
3912 /etc/mke2fs.conf file.
3914 The mke2fs program will no longer complain and request the -f option
3915 when the user tries to create a filesystem with greater than 2**31
3918 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
3919 adjust the mke2fs.conf file so filesystems for the Hurd are created
3920 with a blocksize of 4096 and inode size of 128, which is all it knows
3921 how to handle. (Addresses Debian Bug: #471977)
3923 Mke2fs will always make sure that lost+found always has at least 2
3924 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
3926 Resize2fs will now print the minimum needed filesystem size if given
3927 the -P option, and will resize the filesystem to the smallest possible
3928 size if given the -M option.
3930 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
3931 blocks are consumed during an off-line resize.
3933 The "ls" command in debugfs now supports the -p option, which causes
3934 it to quote the filenames so that spaces or tabs in directory entries
3935 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
3936 Sourceforge Feature Request: #1201667)
3938 Fix a potential off-by-one buffer overflow in the fs_device_name in an
3941 The chattr program will return a non-zero exit code in case of
3942 failures, and error messages can be suppressed with the -f option.
3943 (Addresses Red Hat Bugzilla: #180596)
3945 Fix a bug in badblocks which caused it to overrun an array and likely
3946 crash if more than 8 test patterns are specified using the -t option.
3947 (Addresses Debian Bug: #487298)
3949 Add support to badblocks to limit how quickly it reads from the disk
3950 drive (so it can be used for background scrubbing), and so it will
3951 abort after finding a given number of errors.
3953 Remove support for the legacy big-endian filesystem format which only
3954 existed on extremely long-dead PowerPC kernels almost a decade ago.
3956 Remove MASIX support from e2fsprogs.
3958 Add I/O statistics reporting to e2fsck.
3960 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
3963 Fixed various Debian packaging issues --- see debian/changelog for
3964 details. (Addresses Debian Bugs: #487443, #487675, #490003)

3985 Clean up the badblocks group so to make it more portable and robust.
3987 Avoid using predictable filenames in /tmp in blkid's regression test
3988 suite. Also remove bashism's in the regression test script.
3990 If the configure script is given --with-diet-libc, don't use thread
3991 local storage, since diet libc doesn't support TLS. (Addresses
3992 Sourceforge Bug: #2000654)
3994 Fix the blkid regression test suite to tolerate older versions of
3995 mkswap that don't support the -U option.
3997 A few library routines have been converted to support 64-bit block
3998 numbers; in particular, the I/O manager functions, the test_io,
3999 inode_io, and unix_io managers have all be converted to support 64-bit
4002 Debugfs can now be extended for use by test programs. See
4003 lib/ext2fs/extents.c for an example for how it can be used. The test
4004 program links against the debugfs object files, and provides
4005 additional commands by defining an auxiliary libss command table.
4007 The lazy_bg filesystem feature, which was only used by developer's
4008 testing, has been removed since it has been largely supplanted by
4009 uninit_bg. This also simplifies the code.
4012 E2fsprogs 1.40.11 (June 17, 2008)
4013 =================================
4015 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
4016 percentage of reserved blocks. (Addresses Debian Bug: #452639)
4018 Updated Spanish and Catalan translations.
4020 Fixed various Debian packaging issues --- see debian/changelog for
4021 details. (Addresses Debian Bugs: #483962, #483023)
4023 Add detection for ZFS volumes to the libblkid library.
4025 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4026 (Addresses Debian Bug: #486463)
4031 Fix marginal C code in probe_lvm2() function to the blkid library more
4032 portable for older compilers.
4034 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
4036 Fix ext2fs_swap{16,32,64} functions so they can be used by external
4037 applications on big-endian machines. (Addresses Debian Bug: #484879)
4040 E2fsprogs 1.40.10 (May 21, 2008)
4041 ================================
4043 When deciding whether or not to revalidate a blkid cache entry, if the
4044 device's mtime is newer than the last time the cached entry was
4045 validated, force a revalidation.
4047 Fix a potential data corruption bug in e2fsck in the journal replay.
4048 The chances of this is happening is extremely remote, especially the
4049 default data=ordered or data=writeback modes. However, if a block
4050 which has been journalled starts with the first four bytes 0xc03b3998,
4051 when e2fsck replays the journal, those four bytes will be replaced
4052 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
4053 metadata to begin with those fatal 4 byte sequence, and unless
4054 data=ordered mode is in use, data blocks are never journalled.
4056 Updated German, Dutch, Swedish, and Vietnamese translations.
4061 Fixed various Debian packaging issues --- see debian/changelog for
4064 Remove default sizes of types when cross compiling, since autoconf
4065 2.50 can figure this out automatically now.
4068 E2fsprogs 1.40.9 (April 27, 2008)
4069 =================================
4071 SuSE's security team audited uuidd and came up with a few minor
4072 issues. None of them are serious given that uuidd runs setuid as a
4073 unprivileged user which has no special access other than libuuid
4074 directory, but it's good to get them fixed.
4076 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
4077 work correctly with in-inode extended attributes.
4079 Updated German, Czech, Dutch, French, Polish, Swedish, and Vietnamese
4082 Debugfs will avoid using a pager if the standard output is not a tty.
4084 Fix debugfs and tune2fs to correctly handle daylight savings time when
4085 parsing a time string.
4087 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4089 Fix fsck completion bars when multiple filesystems were being checked
4090 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
4091 #203323, Addresses Sourceforge Bug: #1926023)
4093 Fix fsck so that progress information is sent back correctly when
4094 multiple filesystems are being check and the output of fsck is being
4095 redirected to a file descriptor. Also, include the device name (w/o
4096 spaces) in the progress information sent back via a file descriptor.
4097 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
4100 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
4102 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
4103 signal to its child process.
4105 Fix mke2fs's creation of are resize inode when there is a non-standard
4106 s_first_data_block setting.
4108 Fix bug in blkid when run by an unprivileged user; most devices were
4109 not reported correctly. 9Addresses Launchpad Bug: #220275)
4111 Mke2fs will not allow the logically incorrect combination of
4112 resize_inode and meta_bg, which had previously caused mke2fs to create
4113 a corrupt filesystem.
4115 Fix fsck in German locales so that a 'j' means yes.

4122 Fixed various Debian packaging issues --- see debian/changelog for
4125 Update valgrind options in test_script to work with valgrind 3.2.3

4134 Fix build system so that if texinfo is not installed, it won't print a
4135 (harmless) error message.
4138 E2fsprogs 1.40.8 (March 13, 2008)
4139 =================================
4141 Fixed e2image -I so it works on image files which are larger than 2GB.
4143 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
4144 the size is larger than the number of blocks found in the inode, don't
4145 try to allocate extra empty blocks at the end of the directory to make
4146 up the difference; there's no point to doing that. In addition, if
4147 the size is not a multiple of a blocksize, always fix it.
4149 E2fsck handled a pass 2 "should never happen error" by not giving
4150 enough information and then core dumping. Unfortunately, it was all
4151 too easy to trigger the "should never happen" situation if a
4152 directory's inode size was not correct. This has been fixed, but
4153 e2fsck has also been taught how to handle this situation more
4154 gracefully, by simply removing the inode hash tree information, so
4155 that it can be rebuilt again after e2fsck's pass 3. (Addresses
4156 Launchpad Bug: #129395)
4158 Resize2fs had a bug resizing large inodes with extended attributes
4159 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
4160 completely on big-endian systems such as PowerPC. The bug should be
4161 completely fixed now. Yay for regression test suites. (Addresses Red
4162 Hat Bugzilla: #434893)
4164 Updated German, Czech, Dutch, Polish, Swedish, and Vietnamese
4165 translations. Many thanks to Philipp Thomas from Novell for stepping
4166 up to become the new German translation maintainer! (Addresses Debian
4167 Bugs: #302512, #370247, #401092, #412882).
4169 When e2fsck is clearing a corrupt inode's HTREE directory information,
4170 make it clear that it is just clearing the HTREE information, not the
4173 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4178 Add new functions, ext2fs_dblist_get_last() and
4179 ext2fs_dblist_drop_last(), which allows the caller to examine the last
4180 directory block entry added to the list, and to drop if it necessary.
4182 Fixed a portability problem in libblkid with DJGPP.
4184 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
4185 to Philipp Thomas for pointing this out.
4187 If the info files are not built, change "make install" so it doesn't
4188 fail with an error code.
4191 E2fsprogs 1.40.7 (February 28, 2008)
4192 ====================================
4194 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
4195 depreciate the -s option, since it can result in filesystems which
4196 e2fsck can't fix easily. There are very good reasons for wanting to
4197 disable sparse_super; users who wants to turn off sparse_super can use
4198 debugfs. (Addresses Sourceforge Bug: #1840286)
4200 Add missing options to mke2fs's usage message. (Addresses Sourceforge
4203 Fix bug in resize2fs when large (greater than 128 byte) inodes are
4204 moved when a filesystem is shrunk; it was only moving the first 128
4205 bytes, so extended attributes were not getting moved. (Addresses Red
4206 Hat Bugzilla: #434893)
4208 E2fsck now prints an explicit message when the bad block inode is
4209 updated, to avoid confusion about why the filesystem was modified.

4212 Allow mke2fs and tune2fs manipulate the large_file feature.
4213 Previously we just let the kernel and e2fsck do this automatically,
4214 but e2fsck will no longer automatically clear the large_file feature.
4215 It still isn't really necessary to worry about this feature flag
4216 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
4219 Suppress message about an old-style fstab if the fstab file is empty.
4220 (Addresses Debian Bug: #468176)
4222 Fix (really minor) bug in debugfs's find_free_block so it avoids
4223 reporting a free block more than once if there are too few free blocks
4224 in the filesystem. (Addresses Sourceforge Bug: #1096315)
4226 Change e2fsck to no longer clear the LARGE_FILES feature flag
4227 automatically, when there are no more > 2GB files in the filesystem.
4228 It's been almost a decade since there have been kernels that don't
4229 support this flag, and e2fsck clears it quietly without telling the
4230 user why the filesystem has been changed.
4232 Fix bug which could cause libblkid to seg fault if a device mapper
4233 volume disappears while it is being probed. (Addresses RedHat
4236 Enhance e2fsck's reporting of unsupported filesystem feature flags.
4237 (Addresses Sourceforge Feature Request: #1175808)
4239 Fix option syntax in dumpe2fs for explicit superblock and blocksize
4240 parameters. What was currently documented in the man page has been
4241 broken for some time, due to getopt() implementation changes. The
4242 option syntax has been changed to one which is can be more portable
4243 supported and which is consistent with the format for extended options
4244 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
4246 Add support to tune2fs to clear the resize_inode feature. This
4247 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
4249 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
4252 Add support for setting RAID stride and stripe-width via mke2fs and

4281 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
4282 partially filled-in filesystem object on an error, so that e2fsck can
4283 print more intelligent error messages.
4285 Add a new function e2p_edit_feature2() which allows the caller to
4286 specify which feature flags are OK to set or clear, and which returns
4287 more specific information about feature flags which are not allowed to

4351 ===================================
4353 Fix a potential overflow big in e2image if the device name is too
4356 Mke2fs will now create new filesystems with 256 byte inodes and the
4357 ext_attr feature flag by default. This allows for much better future
4358 compatibility with ext4 and speeds up extended attributes even on ext3
4361 Teach e2fsck to ignore certain "safe" filesystem features which are
4362 set automatically by the kernel. Having the kernel set features
4363 automagically behind the user's back is a bad idea, and we should try
4364 to break the kernel of this habit, especially for the newer ext4
4365 feature flags. But for now, we will try to avoid needless full checks
4366 which can annoy users who are doing fresh installs.
4368 Add support in tune2fs and mke2fs for making a filesystem as being "ok
4369 to be used with test kernel code". This will be needed for using test
4370 filesystems with the latest ext4 kernel code.
4372 Change e2fsck -fD so that it sorts non-htree directories by inode
4373 numbers instead of by name, since that optimizes performances much
4374 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
4376 If e2image fills the disk, fix it so it exits right away instead of
4377 spewing large numbers of error messages.
4378 (Addresses-Sourceforge-Feature-Request: #606508)
4380 If ftruncate64() is not available for resize2fs, let it use ftrucate()
4381 instead, but have it check to see if the size would get truncated, and
4382 skip calling ftruncate in that case.
4384 Add support for detecting HFS+ filesystems in the blkid library.
4386 Add support in the blkid library for ext4/ext4dev filesystems.
4388 Fix a bug in blkid where it could die on a floating point exception
4389 when presented with a corrupt reiserfs image.
4391 Fix blkid's handling of ntfs UUID's so that leading zeros are printed

4442 Improve time-based UUID generation. A new daemon uuidd, is started
4443 automatically by libuuid if necessary. This daemon is setuid to allow
4444 updates to /var/lib/libuuid, so the clock sequence number can be

4452 changes in the feature flags. (Addresses Debian Bug: #454926)
4454 Fix fsck to only treat the '#' character as a comment at the beginning
4455 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

4494 E2fsprogs 1.40.3 (December 5, 2007)
4495 ===================================
4497 Fix a potential security vulnerability where an untrusted filesystem
4498 can be corrupted in such a way that a program using libext2fs will
4499 allocate a buffer which is far too small. This can lead to either a
4500 crash or potentially a heap-based buffer overflow crash. No known
4501 exploits exist, but main concern is where an untrusted user who
4502 possesses privileged access in a guest Xen environment could corrupt a
4503 filesystem which is then accessed by the pygrub program, running as
4504 root in the dom0 host environment, thus allowing the untrusted user to
4505 gain privileged access in the host OS. Thanks to the McAfee AVERT
4506 Research group for reporting this issue. (Addresses CVE-2007-5497.)
4508 Fix heuristics in blkid which could cause a disk without partitions to
4509 be incorrectly skipped when a loopback device is present. (Addresses
4510 Red Hat Bugzilla #400321.)
4512 Fix e2image so that in raw mode it does not create an image file which
4513 is one byte too large.
4515 Change mke2fs's usage message so it recommends the preferred -E option
4516 instead of the deprecated -R option.
4518 Enhance the blkid library so it will recognize squashfs filesystems.
4519 (Addresses Red Hat Bugzilla #305151.)
4521 Enhance e2fsck so it will force the backup superblocks to be backed up
4522 if the filesystem is consistent and key constants have been changed
4523 (i.e., by an on-line resize) or by e2fsck in the course of its
4526 Enhance blkid's detection of FAT filesystems; so that USB disks with
4527 only a single bootable partition will not get missed.
4529 E2fsck will no longer mark a filesystem as invalid if it has time
4530 errors (i.e., if superblock mount time or last write time is in the
4531 future) and the user refuses to fix the problem.
4533 The Ubuntu init scripts don't properly set the system time correctly
4534 from hardware clock if the hardware clock is configured to tick local
4535 time instead of GMT time. Work around this as best as we can by
4536 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
4537 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
4540 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
4541 Hat Bugzilla #151533.)
4543 Fix e2fsck so that if the superblock is corrupt, but still looks
4544 vaguely like an ext2/3/4 superblock, that it automatically tries to
4545 fall back to the backup superblock, instead of failing with a hard
4548 Make the e2fsprogs program more robust so that they will not crash
4549 when opening a corrupt filesystem where s_inode_size is zero.
4551 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
4552 arguments are detected as such and the parse error is reported to the
4553 user. (Addresses Debian Bug #435381.)
4555 Change e2fsck so it will not complain if a file has blocks reallocated
4556 up to the next multiple of a system's page size.
4558 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
4559 about (valid) filesystems where the inode table extends to the last
4560 block of the block group. (Addresses Red Hat Bugzilla #214765.)
4562 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
4563 allocating inode tables for some relatively rare odd disk sizes.
4564 (Addresses Red Hat Bugzilla #241767.)
4566 Add Catalan translation and update Dutch and Swedish translations
4567 from the Translation Project.
4569 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
4570 still had an issue when trying to figure out whether we need to
4571 byte-swap fast symlinks that contained extended attributes.
4573 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4574 (Addresses SourceForge Bug #1821333.)
4580 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
4582 Add "make check" to the RPM spec file
4584 Fix "make install" and 'make uninstall" in misc/Makefile.in so that it
4585 works correctly when the prefix is not the root directory.
4587 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
4588 clean up after themselves by deleting the test.img temporary file
4589 after completing the test.
4591 Fixed a corner case bug ext2fs_unlink() when trying to delete the
4592 first directory entry in a directory block and the last directory
4593 entry in the previous directory block is not in use. Fortunately
4594 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
4595 places where it is extremely unlikely to run into this corner case.
4597 Fix missing dependency which would cause parallel builds to fail.
4598 (Addresses Sourceforge Bug #1842331.)
4600 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
4601 calling open(O_CREATE) with a missing mode parameter.
4603 Fix the test_ss.c in lib/ss so it can be used as an example
4604 application program for the library as well as a regression test
4607 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
4608 are properly passed back up through the call stack.
4610 E2fsprogs 1.40.2 (July 12, 2007)
4611 ================================
4613 A recent change to e2fsck_add_dir_info() to use tdb files to check
4614 filesystems with a very large number of filesystems had a typo which
4615 caused us to resize the wrong data structure. This would cause a
4616 array overrun leading to malloc pointer corruptions and segfaults.
4617 Since we normally can very accurately predict how big the the dirinfo
4618 array needs to be, this bug only got triggered on very badly corrupted
4621 Fix a bug in e2fsck which caused it to incorrectly salvage
4622 directories when the last entry's rec_len is bogusly too big. This
4623 resulted in a nonsense filesystem corruption to be reported, and
4624 required a second run of e2fsck to fully fix up the directory.

4629 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
4633 E2fsprogs 1.40.1 (July 7, 2007)
4634 ===============================
4636 Fix bug which could cause libblkid to loop forever. When revalidating
4637 a partition where there is obsolete information in /etc/blkid.tab, we
4638 end up freeing a the type tag without clearing dev->bid_type, causing
4639 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
4641 The Turkish translation has a bug in it where it has the translation
4642 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
4643 @E, recursively, forever, until the stack fills up and e2fsck core
4644 dumps. We fix this by making e2fsck stop @-expansions after a
4645 recursive depth of 10, which is far more than we need.
4646 (Addresses Sourceforge Bug: #1646081)
4648 Compile the default mke2fs.conf into mke2fs program. People are
4649 getting surprised by mke2fs creating filesystems with different
4650 defaults than earlier versions of mke2fs if mke2fs.conf is not
4651 present. So we now create a built in version of mke2fs.conf file
4652 which is used by mke2fs if the /etc/mke2fs.conf is not present.
4653 (Addresses SourceforgeBug: #1745818)
4655 Improve the config/parse_types.sh helper script. Fix a potential
4656 security problem if e2fsprogs is built as root (as Gentoo does!). In
4657 addition fix the script and how it is called from the configure script
4658 so that it does the right thing when cross-compiling. (Fixes Gentoo
4661 Update Vietnamese, French, and Dutch PO files from the Translation
4662 Project. Also created a new e2fsprogs.pot file for translator.
4664 Fix bogus strip permission errors when building under Debian. When
4665 building the e2fsprogs dpkg's, the dh_strip command emits a large
4666 number of error messages caused by the permissions not being right.
4667 So run dh_fixperms before running dh_strip.
4672 Add new function: profile_set_default(). This function sets the value
4673 of the pseudo file "<default>". If the file "<default>" had
4674 previously been passed to profile_init(), then def_string parameter
4675 will be parsed and used as the profile information for the "<default>"
4678 Fix mk_cmds's error reporting so that it is unambiguous that it is the
4679 mk_cmds script which is generating the error. (Obviates Gentoo patch:
4680 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
4682 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
4683 priority" environment variable that overrides all others, where as
4684 LANG is the lowest priority environment variable. If LC_ALL is set, it
4685 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
4686 the all the rest are set. This will assure that the locale when
4687 running the test suites is the "C" locale. (Obviates Gentoo patch:

4696 Add new blkid -g option which causes the blkid cache to be garbage
4699 Fix a bug in libblkid which could cause the internal field bid_type to
4700 become corrupted. Fortunately bid_type isn't used much, and bid_label

4705 created with a requested RAID stride, and then use it automatically in
4708 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
4709 isn't too big. In some cases Lustre users have tried specifying an
4710 inode size of 4096 bytes, while keeping an inode ratio of one inode
4713 Improve sanity check in e2fsck's algorithm for finding a backup
4714 superblock, so that it won't accidentally find a superblock that was
4715 located in the journal, and then later reject it as being not a valid
4718 Fix e2fsck get_size logic so that it will work with the Linux floppy
4719 driver. The Linux floppy driver is a bit different from the other
4720 block device drivers, in that if the device has been opened with
4721 O_EXCL, it disallows another open(), even if the second open() does
4722 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
4724 Fix error checking of badblock's last-block and start-block arguments.

4747 Fix e2fsck so that it checks all of the blocks in the journal inode
4748 for validity. The original code only checked the direct blocks to
4749 make sure the journal inode was sane. Unfortunately, if some or all
4750 of the indirect or doubly indirect blocks were corrupted, this would

4762 the top-level COPYING file (Red Hat Bugzilla: 166058)
4764 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
4766 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
4768 Remove check in e2fsck which requires EA's in inodes to be sorted;
4769 they don't need to be sorted, and e2fsck was previously wrongly
4770 clearing unsorted EA's stored in the inode structure.

4789 Improve e2fsck's reporting of I/O errors so it's clearer what it was
4790 trying to do when an error happens
4792 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
4793 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
4794 #232663 and LTC Bugzilla: #27634)

4807 Allow the debugfs lcd command to work w/o a filesystem being open.
4808 (Addresses LTC Bugzilla #27513)
4810 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
4811 field on the first pass.
4813 Fix e2fsck to set the file type of the '..' entry when connecting
4814 a directory to lost+found. (Addresses Lustre Bug: #11645)
4816 Enhance e2fsck to recover directories whose modes field were corrupted
4817 to look like special files. This is probably only useful in
4818 artificial test cases, but it will be useful if we ever do the "inodes
4819 in directory" idea for ext4.
4821 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
4824 Fix resize2fs parsing of size parameter (in sector units). This was
4825 actually a bug in libe2p's parse_num_blocks() function. When handling
4826 the 's' suffix, it was ignoring the blocksize information passed in
4827 from the caller and always interpreting the number in terms of a 1k
4828 blocksize. (Addresses Debian Bug: #408298)
4830 There was a floating point precision error which could cause e2fsck to
4831 loop forever on really big filesystems with a large inode count.
4832 (Addresses Debian Bug: #411838)
4834 Fix memory leak in ext2fs_write_new_inode()
4836 Add support for using a scratch files directory to reduce e2fsck's
4837 memory utilization on really big filesystems. This uses the TDB
4838 library. See the [scratch_files] section of the e2fsck.conf man page
4841 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
4842 platform (Addresses Debian Bug: #397044)
4844 Add explanatory message to badblocks that -n and -w are mutually exclusive
4845 (Addresses Debian Bug: #371869)
4847 Allow debugfs and dumpe2fs to support fs features under development.
4849 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
4850 ext2fs_open() , which allows application to open filesystems with features
4851 which are currently only partially supported by e2fsprogs.
4853 Allow unix_io to support offsets greater than 2G (Addresses
4854 SourceForge Bug: #1547922)
4856 Fixed overflow and signed/unsigned problems caused by the number of
4857 blocks or inodes exceeding 2**31 or being close to 2**32-1.
4859 Add support for unsigned directory hash calculations with hints in the
4860 superblock to fix cross-architectural portability for htree
4861 directories with filenames where the high 8th bit is set. (Addresses
4864 Fix resize2fs so that it gives user-intelligible error messages if the
4865 filesystem or the kernel does not support on-line resizing.
4866 (Addresses Debian Bug: #380548)
4868 Require mke2fs -F -F for really dangerous operations, since -F is
4869 needed for less dangerous operations such as creating filesystems
4870 images in regular files, or creating filesystems on whole block
4871 devices. These relatively innocuous usages should NOT be confused
4872 with running mke2fs on an apparently-mounted or in-use filesystem.
4874 Allow the default inode size to be specified into the mke2fs.conf
4877 Make the smallest default journal size is big enough so that on-line
4878 resizing should always work.
4880 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
4883 Fix debugfs coredump when lsdel is run without an open filesystem

4886 Fix debugfs display bug us that bytes that have the high bit set are
4887 displayed as "ec" instead of "ffffffec".
4889 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
4891 Device mapper scanning wasn't working in the blkid library because the
4892 pathnames had an extra "/dev" when they were being probed.
4894 Add GFS/GFS2 support to the blkid library.
4896 Fix blkid support of empty FAT filesystem labels.
4898 Avoid recursing forever (or for a long time) when the blkid library
4899 searches for a device and there are symlinks to directories in /dev.
4901 Avoid unaligned halfword access in blkid when accessing FAT
4902 superblocks, as this will cause Sparc/Solaris systems to throw a

4906 the static link libraries for e2fsck.static if devmapper is enabled.

4909 Improve the (non-installed, for experts only) findsuper program by
4910 printing the uuid and label from the superblocks, as well as the
4911 starting and ending offsets of the filesystem given the information in
4912 the superblock. Omit by default printing superblocks that are likely
4913 found in located in an ext3 journal unless an explicit -j option is
4916 Updated Spanish, French and Dutch translations and added Catalan
4917 translation. (Addresses Debian bug: #411562)
4919 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
4920 determining a partition's size, since binary searching to determine
4921 the device doesn't work on FreeBSD.
4923 Documentation about UUID's is available in enough places, and it's
4924 awkward to deal with debian-legal's insanities. So I'm caving in the
4925 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
4926 don't have do the dfsg tarball. Also remove the rule that only tried
4927 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
4928 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
4930 Fix the info-dir line so that the menu name does not contain a .info
4931 prefix. First of all, it's ugly, secondly, it causes the install-info
4932 command to fail to remove the com_err info file from the
4933 /usr/share/info/dir file when the comerr-dev package is removed and
4934 purged. (Addresses Debian Bug: #401711)
4936 Fixed spelling mistakes, typos, and otherwise clarified man pages.

4947 E2fsck now supports the %It expansion when printing a problem report.
4948 It will print the type of the inode in the problem context.
4950 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
4951 (Addresses Sourceforge Bug: #1565561)
4953 Remove unused variables and other lint/gcc -Wall cleanups
4955 Add check to ext2fs_get_device_size() so it will return EFBIG for for
4956 filesystems contained in regular files where the filesystem image size
4957 is returned by stat64().
4959 Set local environment variables to C so mk_cmds and compile_et always
4960 work. (Addresses SourceForge Bug: #1532177)
4962 Added the 64-bit byte swapping function ext2fs_swab64().
4964 Added two new helper functions to prevent 2**31/2**32-1 overflow
4965 problems: ext2fs_div_ceil() and e2p_percent().
4967 Create new ext2fs library inline functions ext2fs_group_first_block()
4968 and ext2fs_group_last_block() in order to calculate the starting and
4969 ending blocks in a block group.
4971 Create the generated files read-only to remind developers not to edit them.
4973 Add support for autoconf 2.60 (with backwards compatibility for older
4974 versions of autoconf).
4976 Added an "make rpm" target to top-level Makefile
4978 Added various FreeBSD portability fixes.
4980 Exclude mercurial files from the RPM build tree to speed up copy/build.
4982 Use root_sysconfdir to define the locations of mke2fs.conf and
4983 e2fsck.conf instead of using a hard-coded /etc pathname.
4985 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
4987 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
4989 If diff -u is supported, use it to report test failures.
4991 Updates/improvements to RPM spec file
4993 Add on-disk format definitions for the following new features:
4994 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
4995 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
4996 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
4998 Add a new make target "checked-failed" in the tests directory which
4999 reruns any failed tests
5001 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
5003 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
5004 pointer dereferences, memory leaks, etc. None were security-critical
5007 Fix up usage and decrement error messages in the test_icount program
5009 Add debugging code to the com_err library; if the environment variable
5010 COMERR_DEBUG is set to 1, print out debugging messages as error tables
5011 are added and removed from the com_err library. If the
5012 COMERR_DEBUG_FILE environment variable is set (and the process is not
5013 setuid) the debugging messages may be redirected to a file.
5015 Change all of the e2fsprogs programs to use the newer add_error_table()
5016 and remove_error_table() interfaces instead of the much older
5017 initialize_*_error_table() function.
5019 Add TDB support into the ext2fs library. This allows us to have a
5020 guaranteed library we can count on always being present so we can
5021 store data in an on-disk database.
5023 Add support for using TDB to store the icount data, so we don't run out
5024 of memory when checking really large filesystems.
5026 Change the regression test suite so that it skips empty test directories.
5028 Define the l_i_iversion field in ext2_inode. The l_i_version field is
5029 now defined from the old l_i_reserved1 field in the ext2 inode. This
5030 field will be used to store high 32 bits of the 64-bit inode version
5033 Add Makefile production rule for e2fsprogs.spec in case it gets
5036 Add new function profile_get_uint() to allow for a clean way to fetch
5037 unsigned integers from the context.
5039 Add test to make sure the ext2 superblock structure is 1024 bytes.
5041 Fix typo in name of f_dup4 regression test
5043 Add new function blkid_gc_cache() which performs a garbage collection
5044 pass on the /etc/blkid.tab file.
5046 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
5047 general, only e2fsck (after the filesystem is clean), tune2fs, and
5048 resize2fs should change the backup superblocks by default. Most
5049 callers of ext2fs_open() should not be touching any superblock fields
5050 which require the backups to be touched.
5052 Add new function to libext2fs, ext2fs_default_journal_size(), which
5053 returns the default journal size.
5056 E2fsprogs 1.39 (May 29, 2006)
5057 =============================
5059 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
5060 between 2**31 and 2**32 blocks.
5062 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
5063 configure the filesystem features, blocksize, and inode_ratio for
5064 different filesystem types.
5066 Mke2fs will now create filesystems hash trees and on-line resizing
5067 enabled by default, based on the new /etc/mke2fs.conf file.
5069 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
5070 filesystem device node in exclusive mode to prevent accidents by
5071 system administrators. In the case of resize2fs and mke2fs, it will
5072 only use exclusive mode if the filesystem is not mounted.
5074 Fixed a bug in mke2fs which caused it to to fail when creating the
5075 resize inode for large filesystems. (Addresses Debian Bug #346580)
5077 When allocating space for the RAID filesystems with the stride
5078 parameter, mke2fs will now place each portion of the group's inode
5079 table right up after the superblock (if present) in order to minimize
5080 fragmentation of the free space.
5082 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
5083 efficiently by writing the inode and block bitmaps in one pass, thus
5084 reducing the number of disk seeks required.
5086 Add support for on-line resizing to resize2fs.
5088 Fix blkid library so that logic to determine whether or not a device's
5089 cached information in /etc/blkid.tab needs to be verified or not
5090 doesn't get confused by a system clock which is insane (for example,
5091 if the battery is dead on a Macintosh running PPC Linux. (Addresses
5092 Red Hat Bug: #182188)
5094 The blkid library will now store the UUID of the external journal used
5095 by ext3 filesystems, so that in the future, the userspace mount binary
5096 can use this to find the location of the external journal and pass
5097 this information to the kernel.
5099 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
5100 control how various options should be handled. See the e2fsck.conf
5101 man page for more details. (Addresses Debian Bug: #150295)
5103 E2fsck now prints an explanatory message when delaying a filesystem
5104 check when the system is running on battery. (Addresses Debian Bug:
5107 E2fsck will detect if the superblock's last mount field or last write
5108 field is in the future, and offer to fix if so. (Addresses Debian Bug
5109 #327580) These problems will be fixed automatically in preen mode
5110 since Debian's boot sequence bogusly doesn't set the time correctly
5111 until potentially very late in the bootup process, and this can cause
5112 false positives which will cause users' systems to fail to boot.
5113 (Addresses Debian Bugs #343662 and #343645)
5115 E2fsck now checks to see if the superblock hint for the location of
5116 the external journal is incorrect, and if so, offer to update it.
5117 (Addresses Debian Bug: #355644)
5119 Fix e2fsck from segfaulting on disconnected inodes that contain one or
5120 more extended attributes. (Addresses Debian Bug: #316736, #318463)
5122 E2fsck will stop and print a warning if the user tries running a
5123 read/write badblocks test on a read-only mounted root filesystem.
5125 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
5126 C. Thompson for pointing these out; they were originally found using
5129 When resizing a file containing a filesystem, resize2fs will expand or
5130 truncate a file as necessary. (Addresses Debian Bug: #271607)
5132 Resize2fs will now automatically determine the RAID stride parameter that
5133 had been used to create the filesystem, and use that for newly created
5134 block groups. The RAID stride parameter may also be manually specified
5135 on the command line using the new -S option to resize2fs.
5137 Fix mke2fs so that it correctly creates external journals on
5138 big-endian machines (such as a S/390).
5140 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
5141 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
5142 Chambraud for pointing this out.)
5144 Dumpe2fs will now print the size of the journal (if present).
5146 Fix debugfs's set_inode_field command so it can properly set the frag,
5147 fsize, uid_high, gid_high, and author fields in the inode instead of
5148 silently failing, and so that setting the i_size actually sets i_size
5151 Add a new debugfs command, set_current_time, which sets fs->now so
5152 that regression test suites can repeatedly modify the filesystem's
5155 Fix a bug in debugfs's icheck which would incorrectly report the owner
5156 of an extended attribute block.
5158 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
5159 print a usage message when an illegal option character is given.
5161 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
5162 so it won't core dump. (Addresses SourceForge bug #1424311)
5164 Fix mklost+found so that it creates a full-sized directory on
5165 filesystems with larger block sizes.
5167 Fix a file descriptor leak in blkid library.
5169 Fix a display bug in "badblocks -sv" so that the done message properly
5170 clears the block number at the end of the test. (Addresses Debian Bug
5173 Allow fractional percentages to the -m option in mke2fs and tune2fs
5174 (Addresses Debian Bug: #80205)
5176 Use fstat/fstat64 in getsize.c if the the target is a regular file,
5177 instead of attempting to do a binary search. Fix some fd leaks in
5180 Add support for device mapper library to the blkid library to ensure
5181 that the "best" (i.e., leaf) device is probed by the blkid library.
5183 Fix the blkid library so that it notices when an ext2 filesystem is
5186 Improve the blkid's library VFAT/FAT detection; it now understands
5187 labels stored in the root directory, and is more paranoid about
5188 checking the FAT superblock values.
5190 Fixed a fd leak in the uuid library which was causing problems for the
5191 LVM tools. (Addresses Debian Bug: #345832)
5193 Add support for the reiser4 and software suspend partitions to the
5194 blkid library. Also add support for extract the label from iso9660
5197 Fix a compile_et bug which miscount the number of error messages if
5198 continuations are used in the .et file.
5200 Add extra sanity checks to protect users from unusual circumstances
5201 where /etc/mtab may not be sane, by checking to see if the device is
5202 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
5205 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
5206 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
5208 Fix use-after-free bug in e2fsck when finishing up the use of the
5209 e2fsck context structure.

5229 Bugs: #360661, #360317)
5231 Fixed the Makefile so that they work correctly on newer versions of
5232 GNU make (i.e., 3.81).
5234 Add valgrind support to the regression test suites, and eliminate
5235 false positives from valgrind.
5237 Add a regression test suite for the blkid library.
5239 Fix a fencepost error in resize2fs caught by valgrind.
5241 Fix compiler warnings about missing memcpy prototypes.
5243 We no longer have the sparc assembly code in the header file any more,
5244 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
5245 break compiles on the sparc architectures when using gcc.
5247 In the libext2fs library, add the new field fs->now which if non-zero
5248 is used instead of the system time when setting various filesystem
5249 fields (last modified time, last write time, etc.)
5251 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
5252 ext2fs.h which is needed since the inline functions use memcpy().
5253 (Addresses Sourceforge Bug #1251062)
5255 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
5256 the build system when building files in the util directory which are
5257 needed during the build process. This avoids potential problems when
5258 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
5259 are not recognized as valid by the host compiler. (Addresses
5260 Sourceforge Bug #1261547)
5262 Clean up the blkid library by making the superblock and generic i/o
5263 functions to be more generic. Clean up interface to the probe
5264 function, and fix memory leak. Finally, remove an unneeded reference
5265 to probe.h in the lib/blkid/resolve.c
5267 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
5268 of invalid block #'s.
5270 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
5271 indicate that the the function read/writes the memory location.
5273 Fix various gcc -Wall complaints.
5275 Add a dependency to make sure that the subdirectories are created
5276 before creating all of the object files, in order to address parallel
5277 build problem in the library Makefiles. (Addresses Sourceforge Bug:
5280 Add $(LDFLAGS) to the command line argument when generating an ELF or
5281 Solaris shared library, to allow cross-compile and other builds that
5282 might need to specify -L paths to needed libraries. (Addresses
5283 Sourceforge Bug #1261549)
5285 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
5286 intended for testing purposes. It allows an ext2/ext3 developer to
5287 create very large filesystems using sparse files where most of the
5288 block groups are not initialized and so do not require much disk
5289 space. Eventually it could be used as a way of speeding up mke2fs and
5290 e2fsck for large filesystem, but that would be best done by adding an
5291 RO_COMPAT extension to the filesystem to allow the inode table to be
5292 lazily initialized on a per-block basis, instead of being entirely
5293 initialized or entirely unused on a per-blockgroup basis.
5295 Fix backwards compatibility so e2fsprogs will better compile on Linux
5298 Make test scripts more robust against locale-related environment variables
5300 Fix type warning problem with sizeof() in ext2fs_open2().
5302 Fix type warning problem with time_t in debugfs.
5305 E2fsprogs 1.38 (June 30, 2005)
5306 ==============================
5308 Fix blkid's test programs (built with "make check") compile correctly
5309 even without "configure --enable-blkid-debug".
5311 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
5312 type aliasing rules on newer gcc compilers. (Addresses Red Hat
5315 Fix com_err library to make it more compatible with recent changes
5316 made to the com_err library in MIT Kerberos V5 version 1.4.
5317 (Addresses Sourceforge Bug #1150146)
5319 General cleanup of messages printed by e2fsprogs programs for grammar,
5320 consistency, and to make life easier for translators. Fixed a few
5321 strings containing English that had not been marked as needing
5322 translations. Removed strings that do not need to be translated, to
5323 make life easier for translators.
5325 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
5326 test to see if a device appears to be in use instead of just relying
5327 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
5329 Fix portability problem in the filefrag program affecting platforms
5330 where the size of an integer is smaller than the size of a long.
5331 (Addresses Debian Bug #309655)
5333 Mke2fs will now use a larger journal by default for filesystems
5334 greater than 4GB. (128 MB instead of 32MB).
5336 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
5337 unless forced. This is to avoid signed vs. unsigned kernel bugs in
5338 block numbers that still need to be fixed.
5340 The blkid program has a new option which will more efficiently search
5341 for device when it is known (or expected) that only one matching
5342 device will be found in the system, such as when doing a lookup by
5345 Debian's e2fsprogs-specific initrd fragment will avoid including
5346 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
5347 and LD_LIBRARY_PATH, and filtering out libraries found in
5348 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
5350 Fixed a potential portability issue in the blkid programs for
5351 architectures where the char type is unsigned. (Addresses Sourceforge
5354 Fix a bug in filefrag so that it doesn't falsely count an extra
5355 discontinuity when the first block found is an indirect block.
5356 (Addresses Debian Bug #307607).
5358 Fix blkid's recognition of cramfs filesystems, and enhance it to be
5359 able to handle cramfs labels.
5361 Fix debugfs's stat command to not core dump when a filesystem is not
5364 Fix e2fsck's handling of error conditions caused by the resize inode
5365 claiming blocks that are also used by other inodes, a filesystem
5366 corruption which was commonly caused by a bug in Fedora Core 3's
5369 Fixed bug in filefrag which caused it to fail on non-ext2/3
5370 filesystems. (Addresses Debian Bug: #303509)
5372 If the superblock last mount time indicates that the system clock may
5373 not be accurate, then e2fsck will omit checking inodes' deletion time
5374 field for indications of a potential corrupted orphaned inode list.
5375 (Previously e2fsck only omitted these LOW_DTIME checks when the
5376 superblock's last write time looked insane.)
5378 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
5379 (Addresses Debian bug #302200)
5381 Make the blkid library more paranoid about being run from setgid
5382 programs, and to use __secure_getenv() from libc if it is available.
5384 Fixed spelling mistakes, typos, and otherwise clarified man pages.
5385 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
5386 and Sourceforge Bug: #1189803)
5388 Updated and fixed translations.
5390 Fixed various Debian packaging issues --- see debian/changelog for
5396 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
5397 changed to take an unsigned int for the bit number. Negative bit
5398 numbers were never allowed (and didn't make any sense), so this should
5399 be a safe change. This is needed to allow safe use of block numbers
5400 greater than or equal to 2**31.
5402 The compile_et program will avoid recreating generated foo_err.c and
5403 foo_err.h files if no changes are necessary. The compile_et program
5404 will also atomically replace these files to avoid a potential parallel
5405 build race problem on SMP systems. (Addresses Sourceforge Bug:
5408 Added a new function to the blkid library, blkid_probe_all_new(),
5409 which only probes newly added disk devices, and change
5410 blkid_find_dev_with_tag() to use this function so that when a
5411 requested tag is not found, devices that were previously not checked
5412 are searched before searching all devices in the system.
5414 Added new functions to the blkid library, blkid_dev_set_search() and
5415 blkid_dev_has_tag().
5417 E2fsck's problem strings can now use @m and @n as abbreviations for
5418 "multiply-claimed" and "invalid", respectively.
5420 The e2fsprog.pot file now has an explanation of how the @-expansion
5421 and %-expansion works, and strings in e2fsck/problem.c which contain @
5422 characters now have comments in e2fsprogs.pot with the @-expansion to
5423 make life easier for translators.
5425 Fixed missing return values in the ext2fs library which could cause it
5426 to return random garbage in certain error conditions.
5428 Allow the current time to be overridden via the E2FSCK_TIME environment
5429 variable for use in regression tests.
5431 The test script driver program now exits with a non-zero status if
5432 there any of its test that it ran failed.
5434 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
5437 Fixed "make check" so that it compiles correctly even when e2fsprogs'
5438 header files have not be installed in the system include directories.
5439 (Addresses Sourceforge Bug: #1180572)
5441 Fixed gcc -Wall nits.
5444 E2fsprogs 1.37 (March 21, 2005)
5445 ===============================
5447 Add support for checking the validity of Extended Attributes stored in
5450 Add support for dumping the contents of large inodes to debugfs,
5451 including the extended attributes stored in inodes.
5453 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
5454 when we create a new inode we make sure that the extra information in
5455 the inode (any extra fields in a large inode and any ea-in-inode
5456 information) is initialized correctly. This can take place when
5457 mke2fs creates the root and lost+found directory, when e2fsck creates
5458 a new root inode or a new lost+found directory, and when the user uses
5459 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
5460 create inode could inherit garbage (or old EA information) from a
5461 previously deleted inode.
5463 Fixed a bug in e2fsck so it would notice if a file with an extended
5464 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
5467 Added support to filefrag to detect files which are using the new
5468 experimental file extents format, and use the non-ext2 algorithm in
5469 that case. Fixed a bug to avoid reporting a false discontinuity if
5470 there is one or more unallocated blocks at the beginning of a file.
5472 Duplicated a check for noticing whether or not the number of blocks
5473 (given a certain blocksize) is greater than 2**32 when the
5474 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
5475 allows mke2fs to automatically use a larger blocksize when creating a
5476 filesystem on a very large device when run on systems that do not
5477 support BLKGETSIZE64.
5479 Fix the I18N build which was broken in e2fsprogs 1.36 because the
5480 build system had been switched to treat the .gmo files as shipped
5481 files (for backwards compatibility with systems that have older GNU
5482 I18N tools installed), but the gen_tarball.in script was still
5483 removing the .gmo files from the official source distribution.
5485 Fixed various Debian packaging issues --- see debian/changelog for
5486 details. (Addresses Debian Bugs ##296769, #299341)
5491 Added new functions to the e2p library which convert between a string
5492 and os_type: e2p_os2string() and e2p_string2os(), and used them to
5493 make the generated binaries more compact.
5495 Fixed a compile-time error on Darwin systems.
5497 Cleaned up the lib/ext2fs Makefile slightly.
5500 E2fsprogs 1.36 (February 4, 2005)
5501 =================================
5503 All of the patches that were applied to Fedora Core 3's
5504 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
5505 lot of bug fixes first. Users of Fedora Core 3 are strongly
5506 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
5508 Add support for filesystem with the online resizing via resize inode
5509 feature. Fixed numerous bugs from the Fedora patches. The Fedora
5510 patches also didn't bother to do any consistency checking on the
5511 resize inode, or add any tests to the regression test suite. The "-R
5512 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
5513 being listed in mke2fs's usage message. All of these shortcomings
5514 have been corrected.
5516 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
5517 program. In order to do this, the user must run the commands:
5519 debugfs -w /dev/hdXXX -R "features ^resize_inode"
5520 e2fsck -f /dev/hdXXX
5522 Optionally, the ext2prepare command can be used to re-enable online
5523 resizing after the filesystem has been fixed.
5525 The fsck program will now accept an optional filedescriptor argument
5526 to the -C option. (The Fedora version of this patch would sometimes
5527 cause fsck to ignore a parameter on fsck's command line in some rare
5530 Make sure e2fsprogs doesn't write garbage into the reserved portion of
5533 Make sure resize2fs releases the blocks belonging to the old inode
5534 table blocks when moving the inode table. (Addresses Debian Bug:
5537 Skip the r_resize_inode test if resize2fs is not compiled (due to
5538 configure --disable-resizer)
5540 E2fsck now checks the summary filesystem accounting information, and
5541 if any of the information is obviously wrong, it will force a full
5542 filesystem check. (Addresses Debian Bug #291571)
5544 Fix e2fsck to not complain when the resize_inode feature is enabled,
5545 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
5548 Fix e2fsck to note delete symlinks that contain an extended attribute
5549 after the ext_attr feature flag has been cleared. (Addresses Red Hat
5552 Add new utility program, copy_sparse.c, which is very useful
5553 for dealing with large sparse files (such as e2image files).
5555 Add support for jnl_blocks[] for debugfs's set_super_value.
5557 Fix filefrag so that it works correctly with sparse files.
5559 Filefrag -v will print first and last blocks.
5561 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
5564 Add mke2fs support so that it can support filesystems larger than 4TB
5565 automatically, by retrying with a 4k blocksize if the device size is
5566 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
5569 Change blkid to test for NTFS first because Windows sometimes doesn't
5570 clear enough of the partition to confuse the probing routines into
5571 thinking the old filesystem type is still valid. (Addresses Debian
5574 Add support for swap partition label and uuid's in the blkid library.
5576 Add support to the blkid library to recognize Oracle ASM volumes.
5578 Make blkid -t display all devices that match the specified criteria,
5579 not just the first one, and work more consistently when the blkid
5580 cache file is not available or set to /dev/null. (Addresses Debian
5581 Bug #290530 and #292425)
5583 Badblocks will now correctly display block numbers greater than
5584 999,999,999 in its progress display.
5586 The tune2fs program will not allow the user from setting a ridiculous
5587 number of reserved blocks which would cause e2fsck to assume the
5588 superblock was corrupt. E2fsck's standards for what is a ridiculous
5589 number of reserved block has also been relaxed to 50% of the blocks in
5592 The blkid library will return vfat in preference to msdos, and ext3 in
5593 preference to ext2 (if the journalling flag is set) so that mount will
5594 do the right thing. (Addresses Debian bug #287455)
5596 Mke2fs will now use the -E option for extended options; the old -R
5597 (raid options) option is still accepted for backwards compatibility.
5598 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
5600 Mke2fs will now accept a size in megabytes, gigabytes, and other units
5601 (via "32m" or "4g" on the command line) if the user finds this more
5602 convenient than specifying a block count.
5604 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
5605 cache coherency problem.
5607 Debugfs now supports a new command, set_inode_field, which allows a
5608 user to manually set a specific inode field more conveniently, as well
5609 as set entries in the indirect block map.
5611 Debugfs's set_super_value command has been enhanced so that the user
5612 can set most superblock fields, including the date/time fields and
5613 some of the more newly added superblock fields.
5615 E2fsprogs programs now accept an offset to be passed to the file
5616 specifiers, via the syntax: "/tmp/test.img?offset=1024".
5618 E2fsprogs programs will now accept blocksizes up to 65536; kernel
5619 support on the x86 doesn't exist for now, but it can be useful on
5620 other architectures with page sizes greater than 4k. There are 2.6
5621 kernel patches out there which enable this, but they are of this
5622 writing still experimental.
5624 The e2image command now takes the -s option which will scramble
5625 directory entries for raw image files.
5627 Fix a file descriptor leak in the filefrag program.
5629 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
5632 Fix bug in debugfs where kill_file would lead to errors when deleting
5633 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
5635 Fix bug in the blkid library when detecting the ocfs1 filesystem
5637 Remove obsolete EVMS 1.x and a.out DLL support.
5639 E2fsck will attempt to recover from a journal containing illegal blocks.
5641 Fixed two potential ordering constraint problems in e2fsck which might
5642 cause the filesystem to be corrupted if e2fsck is interrupted during a
5643 (extremely narrow) race window. Thanks to Junfeng Yang from the
5644 Stanford Metacompilation group for pointing this out.
5646 Fixed bug in e2fsck where it would not accurately detect whether or
5647 not the system is running on adaptor if the ACPI device representing
5648 the AC adapter didn't correspond to the what was used on IBM
5651 Change e2fsck to accept directories greater than 32MB.
5653 Fix e2fsck so that a checkinterval of zero disables a time-based check
5656 Debugfs will check the DEBUGFS_PAGER environment variable in preference
5657 to the PAGER environment variable. (Addresses Debian Bug #239547)
5659 Tune2fs will not mark rewrite the superblock if the feature bitmasks
5662 The debugfs program will set the filetype information when creating a
5665 Add debugfs -d option to use a separate source of data blocks when
5666 reading from an e2image file.
5668 Add e2image -I option which allows the e2image metadata to be
5669 installed into a filesystem.
5671 Fixed bug in the badblocks program which caused "done" to always
5672 appear in English even when a translation was available. (Addresses
5675 The blkid program has a new option -o which controls the output format
5676 of the blkid program; this is makes blkid more convenient to use in
5679 Fix a minor bug in uuid library, which was not using the full 14 bits
5680 of clock sequence when generating UUID's.
5682 Fix a Y8.8888K problem in the uuid library.
5684 Logsave now creates a new session id for itself to avoid getting
5685 killed by init when transitioning between init levels.
5687 Change the licensing of the UUID library to be the 3-clause BSD-style
5688 license; this allows Apple to use the uuid library in Darwin.
5690 Add ocfs and ocfs2 probe support into the blkid library.
5692 Fix a memory and file descriptor leak in the blkid library.
5694 The blkid library will revalidate the device if the system time is
5695 earlier than last verification time of the device, since that
5696 indicates that the system time is probably not trustworthy.
5698 The blkid library will override the default location of the blkid.tab
5699 file by the BLKID_FILE environment variable, if it is available.
5701 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
5703 Add various portability fixes for lame new versions of glibc, Darwin
5704 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
5705 Bugs #239934, #264630, #269044, #255589, #289133)
5707 Add support for Windows 9x/NT under Cygwin.
5709 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
5710 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
5712 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
5714 Update the rpm spec files so that it works better with Fedora core 2
5717 Fixed various Debian packaging issues (see debian/changelog). In
5718 particular, fixed the Debian initrd scripts. (#241183, #248050,
5725 Fixed various gcc -Wall warnings.
5727 The uuid library now has new functions uuid_unparse_upper() and
5728 uuid_unparse_lower() which forces the case of the hex digits to be
5729 upper case, or lower case.
5731 The build process has been sped up by enhancing the subst program
5732 to update the modtime on the generated files even when the generated
5733 file hasn't changed.
5735 The uuid library now uses C99 stdint.h types instead of custom types.
5737 Updated config.guess and config.sub with newer versions from the FSF.
5739 Removed out of date .cvsignore files from the source distribution.
5741 The ext2fs_unlink() function will return an error if both the name and
5742 inode number are unspecified, to avoid doing something surprising
5743 (such as unconditionally deleting the first directory entry).
5744 Directory entries are now deleted by coalescing them with the previous
5745 directory entry if possible, to avoid directory fragmentation. This
5746 is not an issue with the e2fsprogs suite, but may be a problem for
5747 some of the users of libext2fs, such as e2tools.
5749 Add support for version numbers of the form "1.36-rc1".
5751 Fix build of mke2fs.static.
5753 Add basic ext2fs library support for large (EA in inode) inodes.
5755 The test_io mechanism can now abort after n reads or writes to a
5756 particular block. The block is specified by TEST_IO_BLOCK environment
5757 variable, and the read/write count by the TEST_IO_READ_ABORT and
5758 TEST_IO_WRITE_ABORT environment variables. The block data is now only
5759 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
5761 UUID_DEFINE() in the uuid library now creates a static variable, with
5762 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
5763 be used in header files.
5765 Add support for the install-strip and install-shlibs-strip targets, as
5766 suggested by the GNU coding guidelines. "make install" no longer
5767 strips the binaries which are installed.
5769 Remove support for the --enable-old-bitops configure option which was
5770 only for very old sparc systems.
5772 Remove support for --enable-clear-htree; this was only needed during
5773 the early development of the htree patch.
5775 Use Linux-kernel-style makefile output so it is easier to see compiler
5778 Update gettext files to version 0.14.1.
5780 Update to use autoconf 2.5x.
5782 Improved support for compiling e2fsprogs under dietlibc.
5784 Make e2fsprogs portable to Solaris and FreeBSD systems.
5786 Add blkid_verify(), blkid_get_library_version(), and
5787 blkid_parse_version_string() functions to the blkid library.
5789 Add pkg-config files for e2fsprogs's libraries.
5791 Fix "make uninstall" to so that it removes everything that is installed.
5793 Add a configure --enable-maintainer-mode option which enables the
5794 makefile rules to rebuild the configure script from configure.in, and
5795 to rebuild the .gmo files in po directory.
5797 Drop the sparc assembly bitwise operations; it's less efficient
5798 than the GCC 3.4 compile code and triggers compiler warnings on
5799 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
5800 (Addresses Debian Bug #232326)
5803 E2fsprogs 1.35 (February 28, 2004)
5804 ==================================
5806 E2fsck has a new -k option, which in conjunction with the -c options,
5807 preserves the existing badblocks list.
5809 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
5811 E2fsprogs will now deal correctly with symlinks that contain
5812 extended attribute information, which can be created using SE Linux.
5813 (Addresses Debian Bug #232328)
5815 Remove a double longjmp into an invalid stack frame bug in e2fsck.
5816 (This was during an abort sequence, which normally worked on Linux and
5817 caused a core dump on other operating systems.)
5819 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5820 (the NLS library will replace "" with the .po header information).
5822 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
5823 dump due to a division by zero error. (Addresses Debian bug #207082)
5825 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
5826 when reconnecting a directory requires creating a lost+found
5827 directory. (Addresses Debian bug #219640).
5829 Fixed a bug where e2fsck would bomb out if a journal needed to be
5830 replayed when using an alternate superblock.
5832 E2fsck will give an extra grace period before actually forcing a check
5833 if the laptop is running on battery. The next time fsck runs while
5834 the system is on the AC mains, or after the grace period is exceeded,
5835 the filesystem will be checked. (Addresses Debian bug #205177)
5837 E2fsck will inform the user when there are 5 or fewer mounts before a
5838 filesystem check will be forced. (Addresses Debian bug #157194)
5840 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
5841 We now correctly handle the case where there is an overlap between a
5842 block group descriptor or a superblock and a bad block indirect block.
5843 In the case where the indirect block is corrupted, we now suggest
5846 Fix byte swap bugs in e2fsck that caused the journal backup location
5847 in the superblock and symlinks created by SE Linux to be cleared
5848 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
5850 E2fsck -c now replaces the current list of bad blocks with the ones
5853 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
5854 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
5856 Fix a potential bug in e2fsck which could cause it to core dump when
5857 trying to print the location of the backup superblock.
5859 Protect against a potential core dump in e2fsck when printing a
5860 message about backup superblocks.
5862 Add support for backing up the journal inode location in the
5863 superblock. E2fsck will automatically save the journal information in
5864 the superblock if it is not there already, and will use it if the
5865 journal inode appears to be corrupted. ext2fs_add_journal_inode()
5866 will also save the backup information, so that new filesystems created
5867 by mke2fs and filesystems that have journals added via tune2fs will
5868 also have journal location written to the superblock as well.
5869 Debugfs's logdump command has been enhanced so that it can use the
5870 journal information in the superblock.
5872 E2fsck will now update all superblocks when moving the journal inode.
5874 Shrink the size of the e2fsck executable by moving some initialized
5875 variables to the BSS segment.
5877 E2fsck will avoid printing the ^A and ^B characters which bracket the
5878 progress bar when stdout and stdin are a tty device instead of a pipe
5879 to another program. (Addresses Debian bug #204137)
5881 Debugfs's mkdir command will automatically expand the directory if
5882 necessary. (Addresses Debian Bug: #217892)
5884 Fixed a bug in debugfs so that copying a file from /dev/null uses the
5885 correct mode bits. (Addresses Debian Bug: #217456)
5887 If the environment variables DEBUFS_PAGER and PAGER are not set,
5888 debugfs now searches for the appropriate pager to use, beginning with
5889 /usr/bin/pager, and then falling back to 'more' and 'less'.
5890 (Addresses Debian bug #221977)
5892 Debugfs will now support 2.6 device numbers where the major or minor
5893 number may be larger than 255. (Addresses Sourceforge bug #865289)
5895 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
5897 Chattr now stops processing options when it sees '--'. (Addresses
5900 Fix regression tests so they work correctly when e2fsprogs is compiled
5901 with configure --disable-htree.
5903 Fix bug in uuid library when there is no network card and the library
5904 is generating a time-based uuid. The random MAC address was not
5905 correctly generated to be a multicast address.
5907 Add compile_et extensions from Heimdall that were missed the first time
5910 Fix bug in badblocks when using O_DIRECT; we need to make sure that
5911 we're reading from an offset which is page aligned. For read-only and
5912 read-write tests, we try to recover after an error so that we can
5913 continue reading on page-aligned boundaries. (Addresses Debian Bug
5916 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
5919 Updated and clarified various man pages. (Addresses Debian Bug
5920 #206845, #222606, #214920, #232406)
5922 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
5924 Fixed various Debian packaging issues (see debian/changelog).
5929 Fixed a build problem so that e2fsprogs would compile with the
5930 --enable-profile option to configure selected. (Addresses Sourceforge
5933 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
5934 Bugzilla Bug #112448)
5936 Centralize code which calculates the location of the superblock
5937 and block group descriptors so that it is in a single library routine.
5939 Added two new functions, ext2fs_file_open2() and
5940 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
5942 Fix compile_et to output the correct prototype for
5943 initialize_xxx_err_table_r() in the header file. (Addresses Debian
5946 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
5948 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
5949 present. This is for when we try stuffing an int into void * pointer.
5951 Fix type-punning which can cause gcc 3.x to miscompile code by getting
5952 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
5953 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
5954 **'. The EVMS code uses an ugly union approach since we don't want to
5955 modify the EVMS interfaces.
5957 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
5958 aid build process on systems can use invoke GNU make as "gmake".
5960 Added regression testing for mke2fs.
5962 Fixed gcc -Wall nitpicks.
5964 Fixed various compiler warnings.
5966 Add portability fixes for FreeBSD and for using fsctl under Darwin to
5967 support ext2 ioctl's.
5970 E2fsprogs 1.34 (July 25, 2003)
5971 ===============================
5973 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
5974 a tight loop while waiting for a child fsck to exit in some cases.
5975 This burns CPU times which slows down the low-level filesystem check.
5977 Added code to mke2fs to assure that the default block size for a
5978 filesystem is at least as big as the sector size of the device, if it
5981 Changed mke2fs and resize2fs to round the default size of a filesystem
5982 to be an even multiple of the VM pagesize in order to avoid a Linux
5983 kernel bug introduced when the storage of the buffer cache was moved
5984 into the page cache.
5986 Mke2fs will warn the user when creating a filesystem with journalling
5987 and a blocksize greater than 4096. (Addresses Debian bug #193773)
5989 Fixed a bug in resize2fs which caused it to fail on filesystems with a
5990 non-empty bad block list. Resize2fs now discards any blocks on the
5991 badblock list which are no longer part of the filesystem as the result
5992 of a filesystem shrink. (Note: this means that shrinking and then
5993 enlarging a filesystem is no longer a reversible operation;
5994 information about bad blocks in the part of the filesystem which is to
5995 be chopped off will be lost.)
5997 Changed resize2fs so the user can use prefixes to specify the units of
5998 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
5999 and to make the error and informational messages explicitly display
6000 the blocksize used by the filesystem, in order to avoid confusion.
6001 (Addresses Debian bug: #189814)
6003 Added a new debugfs command, dump_unused, which dumps the contents of
6004 all unused blocks to stdout. (Useful as an emergency try-to-find
6005 deleted data command.)
6007 Added a new debugfs command, imap, which prints the location of a
6008 specified inode in the inode table.
6010 Fixed a bug in the badblocks program which caused it to use one bit of
6011 randomness in its non-destructive read/write test, instead of using a
6012 full 8 bits of randomness.
6014 Added a new option (-t) to badblocks, which allows the user to control
6015 the test pattern(s) used when checking a disk.
6017 The blkid probe function now more correctly detects UDF filesystems.
6019 Fixed a bug in the blkid library which caused it to not update its
6020 cache if a filesystem changes from having a label to not having a
6023 Fixed a bug in the blkid library which could avoid an infinite loop
6024 in blkid_find_dev_with_tag() if /proc is not mounted and there the
6025 /etc/blkid.tab file has not yet been created.
6027 Fixed the badblocks program so that the destructive read/write test
6028 honors the -c option, and to use O_DIRECT when possible to avoid
6029 thrashing the system block buffer cache.
6031 Fixed various NLS issues.
6032 - Added Czech and Swedish translations
6033 - Removed testing NYC translation
6034 - Fixed NLS support for message abbreviations in e2fsck
6035 - Remove de-utf.po, since we shouldn't have two versions using different
6037 - Used ngettext() (abbreviated with the macro P_(str1, str2, n)) to
6038 simplify the statistics reporting in e2fsck.
6040 Changed configure.in so that its defaults for *BSD systems no longer
6041 build an fsck wrapper, and not to install in /usr/local by default.
6043 Fixed some minor spelling errors/typo's in e2fsck and the configure
6046 Fixed various Debian packaging issues (see debian/changelog).
6048 Updated and clarified man pages. (Addresses Debian Bug #195616)
6053 Fix gcc -Wall nitpicks.
6055 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
6056 NLS support by default. (Added partial workaround for gettext/Darwin
6057 incompatibility problems.)
6059 Added full MIT KRB5 and Himdall compatibility support to the com_err
6060 library and the compile_et program. (Addresses Debian bug #191900)
6062 Added the blkid_known_fstype() function to the blkid library, which
6063 returns true if it is passed a filesystem type which is recognized by
6064 the blkid probing functions.
6066 Improved the documentation for the blkid library.
6068 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
6069 returns the hardware sector size of a device, if it is available.
6071 Added a dependency in the blkid library's .so file to the uuid
6072 library, since the former uses the latter. (Addresses Debian bug
6075 Added --with-diet-libc and --disable-evms to the configure script.
6077 Fixed a minor memory leak in the badblocks program.
6079 Fixed a portability problem in tune2fs --- not all systems have strptime().
6081 Fixed a portability problem in debugfs with the use of getopt() more
6082 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
6085 Add support Windows support to ext2fs_get_device_size().
6087 Added (normally disabled) debugging code to the Unix I/O manager which
6088 causes it to disable all userspace caching if the NO_IO_CACHE is
6091 Changed the test I/O manager so it can always be linked into e2fsck,
6092 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
6093 configure script. The test I/O manager will only print any debugging
6094 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
6095 variables are set, which specifies which I/O operations are logged and
6096 a block number to watch, respectively. The log messages are sent to
6097 stderr by default, unless a filename is specified via the
6098 TEST_IO_LOGFILE environment variable.
6101 E2fsprogs 1.33 (April 21, 2003)
6102 ===============================
6104 Added a new utility program, logsave, which captures the output of a
6105 command in a log file, even if the containing directory hasn't been
6106 mounted yet (in which case the it saves the output in memory until it
6107 can write out the logfile). This is useful for capturing the
6108 output of fsck during the boot sequence.
6110 Fixed some portability problems that were causing problems under
6111 the Cygwin32 environment.
6113 Mke2fs now interprets a negative number to the -b option as a minimum
6116 Fixed a bug in mke2fs which was incorrectly checking the argument to
6117 the -g option if the default block size was used. (Addresses Debian
6120 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
6121 it can not find filesystem checkers for jfs, reseirfs, and xfs.
6123 E2fsck now updates the global free block and inode counters from the
6124 block group specific counters quietly. This is needed for an
6125 experimental patch which eliminates locking the entire filesystem when
6126 allocating blocks or inodes; if the filesystem is not unmounted
6127 cleanly, the global counts may not be accurate.
6129 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
6130 2.0 is not yet supported; this only pulled in the bug fixes: fixed
6131 possible hangs caused by bugs in calling waitpid, and not setting the
6132 pipe to non-blocking mode; also fixed a file descriptor leak; made
6133 sure all functions call log entry/exit functions.)
6135 Badblocks now flushes its output file as bad blocks are discovered.
6137 The uuid library is now more paranoid about assuming the correctness
6138 of the /dev/random device; it mixes in a stream of bytes from
6139 random/srandom, just in case.
6141 Update Debian files to reflect the fact that I am now the Debian
6142 maintainer of e2fsprogs. Other various Debian-specific packaging
6145 Move the source tarball generation functions from the top-level
6146 makefile to the util/gen-tarball script.
6148 Updated the Turkish .po translation file.
6150 Added Heimdal and MIT krb5 extensions to the com_err library to make
6151 it more compatible with com_err libraries from those distributions.
6153 Changed dumpe2fs to always display the superblock fields relating to
6154 the journalling and/or directory indexing feature even if those
6155 features are not enabled.
6157 Updated and clarify copyright statement vis-a-vis alpha releases of
6160 The ss library will now try to dynamically link to the readline
6161 library and use it if it is present in the system. This means that
6162 the debugfs program now has line editing and history features. The
6163 SS_READLINE_PATH environment variable is used to find a readline or
6164 readline-compatible library.
6166 E2fsck now finds most duplicate filenames (all when rebuilding all
6167 directories via the -D option) and offers to delete or rename
6168 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
6170 Fix bug in e2image. When writing out a raw image file, include data
6171 blocks from symlinks that do not store the symlink within the inode.
6173 Fix bug in resize2fs which incorrectly moved the block and inode
6174 bitmaps for sparse superblock filesystems and incorrectly marked
6175 blocks as in use. (Addresses Debian bug #174766)
6177 Added a new shared library, the blkid library, which efficiently
6178 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
6179 and UUID filesystem specifiers without needing to search all of the
6180 devices in the system. Instead, the device is looked up in a cache
6181 file, and then verified to make sure the blkid cache is correct.
6183 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
6184 the device name, using the blkid library. (Addresses Debian bugs
6187 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
6188 used for spaces in device labels.
6190 Removed 32-bit limitations for debugfs's dump command.
6192 If the user specifies a large number of inodes, Mke2fs will
6193 automatically adjust the number of blocks per group to find a valid
6194 set of filesystem parameters.
6196 Add workaround to detect broken MD devices where when some of the
6197 underlying devices are marked read-only, writes to the MD device are
6198 silently dropped. E2fsck will detect if there is an attempt to run
6199 the journal twice, and abort with an error if this is the case.
6200 (Addresses IBM Bugzilla bug #1226)
6202 E2fsck will print an error if more than one of the -p/-a, -n or -y
6203 options are specified.
6205 E2fsck will fix HTREE corruptions in preen mode, without stopping the
6206 boot process. This is needed because the 2.4 ext2 filesystem
6207 accidentally had the INDEX_FL backwards compatibility code removed.
6209 Mke2fs no longer creates filesystems with the dir_index flag set by
6210 default; the user has to specifically request it.
6212 Update and clarified various man pages. (Addresses Debian bugs
6213 #173612, #175233, #175113, and #170497, #185945, #188318)
6215 Created man page for the mk_cmds program (from the libss library).
6220 Fix various gcc -Wall nits.
6222 Fixed a lot of portability problems that caused e2fsprogs not to build
6223 successfully under Solaris and Apple/Darwin.
6225 Fixed a Makefile dependency to allow building e2fsprogs using parallel
6228 Changes to create a subset distribution which consists only of the
6229 et, ss, uuid, and blkid libraries. The configure script and top-level
6230 makefile were changed to support working with a subset distribution.
6232 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
6233 actually used, and might people who are looking for
6234 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
6236 Updated debian files to fix a number of Lintian warnings.
6238 Updated config.guess and config.sub with newer versions from the FSF.
6240 Removed unnecessary libraries from being linked into the fsck, lsattr,
6241 chattr, and blkid executables.
6243 E2fsprogs 1.32 (November 9, 2002)
6244 =================================
6246 Fixed a bug in the Unix I/O routines which caused needless writebacks
6247 of clean blocks from the unix_io cache (they were erroneously marked
6248 as being dirty, so they were getting written back to disk before
6249 getting evicted from the disk cache). This was harmless, but it
6250 significantly slowed down e2fsck.
6252 Made some other minor optimizations to the Unix I/O routines to save a
6253 small amount of CPU time.
6255 Updated internationalization files.
6258 E2fsprogs 1.31 (November 8, 2002)
6259 =================================
6261 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
6262 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
6263 handling for child process that die unexpectedly. Add a hack to force
6264 mkfs to create filesystems that won't cause problems with hardware
6265 that has 2k or 4k minimum blocksize requirements. Read from child
6266 processes in non-blocking mode, so that the GUI continues to update.
6268 Fix e2fsck so that it returns the appropriate exit code when the root
6269 filesystem has been changed, so that system's rc scripts will be told that
6270 the system needs to be rebooted.
6272 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
6273 was set, some of the descriptor blocks that should have been written
6274 out were getting skipped.
6276 Changed e2fsck to force out changes to the backup copies of the
6277 superblock and block group descriptors when important changes are made
6278 to those data structures.
6280 Fix a bug where e2fsck could erroneously mark a filesystem as being
6281 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
6282 introduced in e2fsprogs 1.28.)
6284 If journal debugging is enabled using --enable-jbd-debug, the debugging
6285 level is now set via the E2FSCK_JBD_DEBUG environment variable.
6287 If byteswapping support is disabled using configure --disable-swapfs,
6288 skip the tests which depend on byte-swapping, so that "make check"
6291 Lsattr will now display the indexed directory flag. Also, some of
6292 the more esoteric compression flags are suppressed unless compression
6293 support has been enabled.
6298 E2fsprogs 1.30 (October 31, 2002)
6299 =================================
6301 When resizing a filesystem, and inodes need to moved, resize2fs will
6302 update the inode's ctime field, and the mtime field of the containing
6303 directories, so that incremental backups using dump/restore will work
6306 In order to avoid spurious errors, e2fsck will check the last
6307 superblock write time to determine whether or not it can safely use
6308 the LOW_DTIME checks to determine if there are inodes on the orphan
6309 inode linked list that had somehow gotten disconnected. (Addresses
6310 Sourceforge bug #620980)
6312 Partition in /proc/partitions that being with the string "lvm" are
6313 considered real partitions even if they do not end with a number.
6315 Fixed a bug in the the uuid generation function, where if /dev/urandom
6316 is not present, but /dev/random is, and there isn't sufficient
6317 entropy, the get_random_byte function could spin a loop forever.
6319 E2fsck, mke2fs, etc. will now reliably notice when image files are
6320 mounted using the loopback interface. (Addresses Sourceforge bug
6323 When flushing buffers (as is done by badblocks, for example) check to
6324 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
6325 FDFLUSH ioctl which causes the MD device driver which causes confusing
6326 syslog messages about obsolete ioctl messages. (Addresses Sourceforge
6329 Debugfs's write command now checks to see if the destination filename
6330 exists before creating it. (Addresses Sourceforge bug #478195.)
6332 When installing man pages, search for compressed man pages using all
6333 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
6335 Fixed a bug in fsck where multiple filesystems specified on the
6336 command were not being checked in parallel due to a logic bug
6337 introduced to support the FSCK_MAX_INST environment variable.
6339 We have added a new superblock field, s_mkfs_time, which indicates
6340 when a filesystem was created. It is set via mke2fs, and printed out
6341 by dumpe2fs, but is not actually touched by the kernel.
6343 Dumpe2fs has been made more robust by not aborting if there is an
6344 error reading the block/inode bitmaps; instead it will still print out
6345 the location of the block/inode bitmaps and inode table.
6347 Add support for the an alternative block group descriptor layout which
6348 allows for on-line resizing without needing to prepare the filesystem
6349 in advance. (This is the incompat feature flag meta_bg.)
6351 Add support for storing default mount options in the superblock, so
6352 that the filesystem can be mounted with specific mount options without
6353 needing to specify them on the mount command line or in the /etc/fstab
6356 Add support for a new inode flag, which is to be used for indicating
6357 the top of directory hierarchies for the Orlov block allocator.
6359 Fix e2fsck so that if it creates the lost+found directory, it does so
6360 with the more appropriate permissions of 0700. Also change
6361 mklost+found so that it also creates the directory 0700.
6363 Fixed format bug in e2fsck if NLS is in use.
6365 Add a German translation for e2fsprogs's NLS support.
6367 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
6368 the beginning of the inode table. This won't matter much, since if
6369 there is a bad block at the beginning of the inode table, the root
6370 directory won't be available. But at least e2fsck won't crash in this
6373 Fixed endian problems in the htree code for e2fsck and debugfs.
6375 When byte-swapping a filesystem on a PPC architecture, byte-swap the
6376 bitmaps since the historical big-endian ext2 variant had byte-swapped
6377 bitmaps, and the ext2fs library assumes this. This fixes the
6378 regression test suite on PPC machines.
6380 Fix e2image so that it handles a bad block in the inode table
6383 E2fsck now uses a more sophisticated algorithm to salvage corrupted
6384 directories that recovers more information in the corrupted directory
6387 E2fsck now performs additional consistency checks on indexed (HTREE)
6390 Fix a bug where e2fsck might get confused about whether a completely
6391 empty directory block is an empty leaf block or an interior htree
6392 node. This could cause e2fsck to get confused into think that a valid
6393 indexed directory was corrupted.
6395 E2fsck no longer creates an empty directory entry at the end of a
6396 directory block when optimizing a directory. This would cause some
6397 earlier versions of the dxdir kernel code to corrupt the directory
6398 when attempting to split a node containing an empty directory entry.
6400 E2fsck could sometimes in rare circumstances leave the indexed flag
6401 set after a small directory was optimized by compressing it instead of
6402 indexing it. (This should never happen in real life, since
6403 directories that small wouldn't have been indexed, but better safe
6406 E2fsck now only updates the master superblock in all cases. This
6407 slightly shortens its run time.
6409 Ext2ed can deal with directory entries of length 0; previously it
6410 would get stuck in an infinite loop.
6412 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
6413 specifiers. (Sourceforge patch #613447)
6415 Badblocks will now work correctly on read-only devices such as
6416 CD-ROM's. (Sourceforge patch #600451)
6418 Updated and clarified man pages. (Addresses Debian bug #167108)
6421 E2fsprogs 1.29 (September 24, 2002)
6422 ===================================
6424 Fixed a bug in e2fsck which could corrupt a directory when optimizing
6425 it (via the -D option) or rebuilding the hash tree index with a 1 in
6426 512 probability, due to a fence post error.
6428 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
6431 Mke2fs now enables the directory indexing flag by default. (Since
6432 this is a compatible feature flag, it's safe to do so.)
6434 Tune2fs will support setting the directory indexing feature flag. It
6435 will automatically set up the default hash algorithm and hash seed
6436 fields in the superblock.
6438 If the bone-headed user enters the root filesystem twice in
6439 /etc/fstab, the -R option which skips the root filesystem will skip
6440 all of them. (Addresses Debian bug #159423). Note! This is not a
6441 precedent for dealing intelligently with any other kind of doubled
6442 entry in /etc/fstab!
6448 Removed perror declaration in lib/et/internal.h. All modern systems
6449 can be expected to define perror() these days. Besides, the lib/et
6450 code wasn't using perror at all anyway. :-)
6453 E2fsprogs 1.28 (August 31, 2002)
6454 ================================
6456 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
6457 for setting the htree flag is not included yet, although it can be
6458 manually turned on via the debugfs program.
6460 Clarified e2fsck error message which is printed when it cannot find
6461 sufficient contiguous block when relocating filesystem metadata.
6463 Added support for building an EVMS plugin module for ext2/3. This
6464 module is substantially the same as the EVMS module shipping with EVMS
6465 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
6466 for use with EVMS 1.0 (which did not include the ext2 plugin module),
6467 if the configure --enable-old-evms flag is given.
6469 Fsck will search through EVMS volumes when trying to resolve
6470 filesystem specifications such as LABEL=xxx or UUID=xxx.
6472 Added a new utility program, /sbin/findfs, which will return
6473 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
6476 Update and clarified various man pages. (addresses Debian Bug #145044,
6477 #146437, #131350, #151990, #144621, #141938)
6479 If there are no filesystems specified on fsck's command line, fsck now
6480 treat that as if the -As options were given. Previously it would
6481 simply do nothing. (Addresses Debian Bug #153102)
6483 Mke2fs no longer treats a failure to be able to clear the MD signature
6484 at the end of the filesystem as a fatal error. (Addresses Debian Bug
6487 The e2p library functions (which are used by lsattr and chattr) now
6488 double check to make sure the file is a regular file or directory
6489 before attempting to use the ext2 ioctls. Some device drivers
6490 unfortunately respond to the ext2 ioctl's with unknown behaviour.
6491 (Addresses Debian Bug #152029).
6493 The extended attribute handling has been updated to correspond with
6494 the latest V2 bestbits ACL code.
6496 Fixed bug in e2fsck which caused it to not clear the dtime field when
6497 processing truncated inodes on the orphan list. This could cause data
6498 loss(!) if a filesystem is rebooted before a truncate has been
6501 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
6502 algorithms. This makes e2fsck much faster in the case of severely
6503 corrupted filesystems where a large number of blocks are claimed by a
6504 large number of inodes. (Thanks to the 2.5 IDE device driver for
6505 inspiring this work.)
6507 Resize2fs has been significantly sped up when shrinking and expanding
6508 a filesystem by a very small number of blocks (for example, when EVMS
6509 is converting a partition to be an EVMS legacy volume).
6511 Added a new option to e2fsck, -D, which will optimize or compress all
6512 of the directories in the filesystem.
6514 E2fsck now catches SIGINT and SIGTERM to make sure it will can
6515 properly clean up and only exit at safe points. Fsck will pass
6516 SIGINT/SIGTERM to its child processes, and wait until they have all
6517 exited before it exits.
6519 The uuid parsing code in the uuid library now properly complains when
6520 an illegally formatted uuid is presented to it. (Addresses Debian bug
6523 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
6524 and 2.4.17, since the workaround can cause problems when using a 2.4
6525 kernel with an old version of glibc built with the 2.2 headers.
6527 Fixed a bug in mke2fs where it wasn't properly clearing the initial
6528 superblock used by other filesystems. (Addresses Debian bug #147256.)
6530 Added support for the synchronous directory feature written by Andrew
6533 The debugfs program can delete directories using the rmdir command.
6535 Add support for 8k and 16k filesystems (for systems with page sizes
6536 that are greater or equal to 8k or 16k, respectively). Note that
6537 these filesystems can not be mounted on x86 systems, or other systems
6538 with only 4k page sizes, due to limitations in the current Linux VM
6541 Resize2fs requires that the filesystem state be valid and have no
6542 errors; otherwise, e2fsck -f must be run first. (Previously it simply
6543 required that the last fsck time be greater than the last mount time.)
6545 Configure now defaults the man pages directory to /usr/share/man on
6548 E2fsck now offers to truncate inodes which contain too many blocks (so
6549 that i_blocks would overflow. Also fixed handling of large sparse
6552 E2fsck now more completely checks for symlink validity, including
6553 requiring NULL termination and length checks.
6555 E2fsck will offer to try forcing a disk write to remap a bad block
6556 after finding a read error when reading a filesystem metadata block.
6558 Fixed a bug in debugfs which caused the -b and -s options to crash
6559 debugfs, as well as breaking the testb, setb, and clearb functions.
6561 Added a bmap command to debugfs which calculates the logical to
6562 physical block mapping for a particular inode.
6564 Fixed a bug in code which checked to see if a device was mounted which
6565 sometimes (rarely) failed in the case of a plain file.
6567 Fixed a bug in resize2fs where when it reported an error, it would
6568 print a message erroneously indicating that the filesystem had been
6569 resized before it aborted.
6571 When resizing a plain file which is smaller than the requested size,
6572 resize2fs will attempt to extended the file so that programs like
6573 e2fsck will not complain that the file is too small.
6575 Resize2fs will print the actual new size of the filesystem when it is
6578 Fixed a bug in debugfs where "ls -l" would report incorrect file type
6579 information on big-endian systems.
6585 Fixed collisions with C++ reserved words.
6587 Added portability fixes for building e2fsprogs on the HURD and AIX.
6589 Added the ext2ed program for creation of test cases. (ext2ed has many
6590 limitations and bugs which make it unsuitable for production use.)
6592 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
6593 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
6594 name_len field is byte swapped on big-endian machines, since in the
6595 V2 structure, name_len is a char field which is doesn't need to be
6596 byte swapped --- except if an old-style kernel had byte-swapped the
6597 name_len field as part of the V1 structure.
6600 E2fsprogs 1.27 (March 8, 2002)
6601 ==============================
6603 The warning messages for mke2fs now go to standard error.
6605 Fixed to make sure "make check" runs all of the test programs with
6606 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
6608 The mke2fs program checks the boot sector for the BSD disk label, and
6609 avoids erasing it if it is there.
6611 Fixed a bug in e2fsck which caused it to core dump if the journal
6612 inode was missing when it was supposed to be there.
6614 E2fsck now prints ranges in pass 5 when printing deltas for the block
6617 Debugfs's "ls -l" command now will print out the file type information
6618 in the directory entry.
6620 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
6621 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
6623 Debugfs can now examine the experimental directory indexing
6626 Fixed bug in debugfs which caused it to core dump if modify_inode is
6627 called without an open filesystem.
6629 The debugfs lsdel command now runs its output through a pager first.
6631 When installing manual pages, remove the compressed manual pages first.
6633 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
6635 Fix the 2.4 resource limitation workaround introduced in 1.26 which
6636 actually broke things on mips32, sparc32, and Alpha platforms.
6638 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
6639 (which is required by the newer libintl libraries).
6644 Fixed various gcc -Wall complaints.
6646 Fixed a few memory leaks in the e2fsck journalling code, and in the
6647 ismounted code checking for a swap device.
6649 Add new inode I/O abstraction interface which exports an inode as
6652 Exported ext2_file_flush as a public interface.
6654 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
6656 Lots of small random portability fixes to make e2fsprogs build under
6657 AIX --- even without the 5L compatibility toolkit, and even using the
6658 uber-crippled AIX native C compiler.
6661 E2fsprogs 1.26 (February 3, 2002)
6662 =================================
6664 Dumpe2fs will keep going now if the bad block inode can't be read.
6665 (Previously it stopped with a fatal error.)
6667 E2fsck will now give an opportunity to run the journal even if the
6668 recovery flag is not set. This is the default behaviour if e2fsck is
6669 using a backup superblock, since the needs_recovery flag will never be
6670 set in the backup superblock copies.
6672 E2fsck now automatically finds the backup superblock/group descriptors
6673 even when the primary superblock is completely destroyed for 2k and 4k
6674 filesystems. (Previously it just guessed/assumed that we were dealing
6675 with a 1k filesystem in that case, and users had to manually specify
6676 the backup superblock number.)
6678 Fixed a bug in e2fsck where it dereferences a null pointer when there
6679 is a problem opening a filesystem in preen mode.
6681 E2fsck now handles external journals correctly; previously it trashed
6682 the external journal device if the journal needed to be replayed.
6684 Work around ulimit incompatibility problem caused by recent 2.4
6685 kernels; the unix IO module will automatically try to set any resource
6686 limits to be infinite on startup.
6688 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
6689 bitmap if it wasn't present and the blocksize was 2k or 4k.
6690 (Addresses Debian Bug #116975)
6692 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
6693 clearing the new V2 fields if they do not make sense or if the ext3
6694 superblock is version 1 superblock.
6696 E2fsck will automatically relocate the ext3 journal from a visible
6697 file (i.e., /.journal) to an hidden inode if the filesystem has been
6698 opened read/write. This allows the users to add a journal while the
6699 filesystem is mounted, but the next time the system is rebooted, the
6700 journal file will disappear. This avoids problems with backups,
6701 stupid operators with superuser bits, etc.
6703 Fix a bug in fsck where it would not support a filesystem type of
6704 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
6706 Fsck now supports fstab entries of the form "ext3,ext2". It will also
6707 automatically identify reiserfs filesystems.
6709 The number of processes spawned by fsck can now be limited using the
6710 FSCK_MAX_INST environment variable.
6712 Fsck now searches the LVM proc hierarchy to find logical volumes which
6713 should be searched for UUID and label information.
6715 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
6716 limit if at all possible, when opening a block device. (The filesize
6717 limit shouldn't be applied against writes to a block device.)
6719 In mke2fs and e2fsck, specifying the -c option twice will now do
6720 a read/write test on the disk. Update the man pages to encourage
6721 using the -c option, and to discouraging running badblocks separately,
6722 since users tend to forget to set the blocksize when running
6725 Mke2fs now automatically clears the immutable attribute on a
6726 pre-existing .journal file left over from a previous failed attempt to
6727 add a journal to an already-mounted filesystem.
6729 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
6732 Mke2fs now creates the lost+found directory with permissions of 0700,
6733 so that files that had previously lived in protected directory are
6734 safe if they get dropped in lost+found and the system administrator
6735 doesn't deal with immediately. (Addresses Debian #bug 118443)
6737 Mke2fs and e2fsck (and all programs that use the
6738 ext2fs_check_if_mounted function) will now properly identify that a
6739 device is mounted, even in cases where devfs has confused things with
6740 multiple devices names with the same identity, or if a dim-witted
6741 system administrator has done something stupid like creating device
6742 file aliases in their home directory. Also now checks for swap devices
6743 by using /proc/swaps. (Addresses Debian bug #106622)
6745 Added a new option (-T) to tune2fs which sets the time a filesystem
6748 Speed up e2image when creating sparse raw image files by optimizing
6749 away excess lseek() system calls.
6751 Fix support of large (> 2GB) files when used as a filesystem in
6752 mke2fs, tune2fs, debugfs, and findsuper.
6754 Debugfs's stat and icheck commands now properly deals with large (>
6757 Debugfs's set_super_value command now prints out the list of valid
6758 superblock fields which can be set using the command.
6760 Debugfs's rm and kill_file command now updates the superblock free block
6761 and inode counts, thus keeping the filesystem consistent.
6763 Debugfs's lsdel command now takes an optional argument which allows
6764 the user to only see the most recently deleted files.
6766 A new command (undel) was added to debugfs which automates
6767 undeleting a deleted inode and linking it back to a directory.
6769 Debugfs's ls command now takes a new option, -d, which lists
6770 deleted directory entries.
6772 Debugfs's testb, freeb, setb, and find_free_block commands now take an
6773 optional count argument.
6775 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
6776 be used to signal that a particular inode should not be eligible for
6777 tail-merging --- this is needed for programs like LILO.
6779 The findsuper (an unreleased, uninstalled utility program) has been
6780 improved to add extra validity checks and to add a progress meter.
6781 (It is still an unsupported program; the officially supported way to
6782 recover from a trashed partition table is to use gpart; findsuper is
6783 for wizards only. :-)
6785 Debugfs was fixed to compile with "configure --disable-swapfs".
6787 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
6789 Added new translation file for Turkish.
6794 Fix general gcc -Wall complaints.
6796 E2fsprogs (mostly) works with the dietlibc.
6798 The programming texinfo file has been expanded to include description
6799 of additional libext2fs functions. (Still not completely done, but a
6800 lot of the more important functions have been documented.)
6802 Added a umask structure to struct_ext2_filsys, which currently only
6803 modifies the behaviour of ext2fs_mkdir(), but if we add any file
6804 creation functions to libext2fs, we should also make sure they respect
6807 The build-rpm script was fixed to be a bit more safe.
6809 The tests' Makefile now has a way of automating test case creation
6810 for e2fsck, using "make testnew".
6812 Created a new function, ext2fs_dir_iterate2 which passes more
6813 information to the callback function (identical to the one used by
6814 ext2fs_dblist_dir_iterate). The directory iterator functions take a
6815 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
6816 directory entries. If the directory entry is deleted, the callback
6817 function will be called with the entry parameter set to
6818 DIRENT_DELETED_FILE.
6820 Added new functions, ext2fs_inode_alloc_stats and
6821 ext2fs_block_alloc_stats, which takes updates block/inode allocation
6822 statistics in the bitmaps, block group descriptors, and superblock
6823 when inodes or blocks are allocated or deallocated.
6826 E2fsprogs 1.25 (September 20, 2001)
6827 ===================================
6829 This is primarily a bug-fix release; no new features were added, but
6830 there are a number of embarrassing bug fixes and cleanups applied.
6832 Fix a bug mke2fs which causes stack garbage to be written to disk when
6833 zapping disk sectors. (This bug could cause mke2fs to core dump for
6834 some kernels, I suspect with security enhancement patches.)
6836 Remove unneeded #include of <linux/config.h> which was breaking
6837 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
6839 Updated tune2fs man page to reflect the fact that adding or removing a
6840 journal doesn't require running e2fsck.
6842 Remove use of AC_REQUIRE from autoconf which had been used to prevent
6843 AC_CANONICAL_HOST from being called twice; unfortunately this causes
6844 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
6845 used outside of autoconf macros. Fortunately, it doesn't seem to be
6846 necessary any more, anyway.
6848 E2fsck will now not fall back to an alternate superblock if the user
6849 specifies the superblock location explicitly on the command-line.
6850 This allows easier recovery from a situation where the primary
6851 superblock and block groups are slightly corrupted, but the backup
6852 superblocks are completely broken.
6854 Fix problem which caused compile_et and mk_cmds to blow up if
6855 e2fsprogs was in a directory with a pathname that contained spaces.
6857 We are now more paranoid about checking the entry in /etc/mtab to make
6858 sure the filesystem is really mounted, since some broken distributions
6859 (read: Slackware) don't initialize /etc/mtab before checking non-root
6860 filesystems. (Slackware also doesn't check the root filesystem
6861 separately, and reboot if the root filesystem had changes applied to
6862 it, which is dangerous and broken, but there's nothing I can do about
6865 Make UUID library C++ friendly by adding appropriate extern "C"
6866 declarations and using const in the function declarations.
6868 Fix up the com_err texinfo file so that it can product a valid info
6869 file (previously, it could only be used to generate paper
6870 documentation using texinfo.tex).
6873 E2fsprogs 1.24a (September 2, 2001)
6874 ===================================
6876 Fix brown-paper bug in mke2fs which caused it to segfault when
6877 printing the version string.
6880 E2fsprogs 1.24 (August 30, 2001)
6881 ================================
6883 Revert the BLKGETSIZE64 support, since for some distributions, this
6884 ioctl has been used by an unofficial kernel patch to update the last
6885 sector on the disk, and this was causing disk corruption problems as a
6888 Mke2fs is now more careful about zapping swap space signatures and
6889 other filesystem/raid superblock magic values so that programs like
6890 mount who try to use heuristics to determine the filesystem type of a
6891 partition are less likely to be confused.
6893 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
6894 regular file (since Andreas Dilger's on-line resizing tools will set
6897 Fixed some minor texinfo, man pages nits for spelling errors,
6898 texinfo warnings, etc. (Addresses Debian bug #110621.)
6900 E2fsprogs program no longer print the filesystem version number
6901 (i.e. 0.5b), since it only confuses people and doesn't serve any real
6904 E2fsck will once again compile under libc5, since it will supply its
6905 own version of strnlen if necessary.
6907 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
6908 when specifying the external journal device. tune2fs will also search
6909 devices looking for the external journal device when removing it.
6911 E2fsprogs 1.23 (August 15, 2001)
6912 ================================
6914 Add initial support for extended attributes (EA); e2fsck will
6915 correctly handle a filesystem with EA's and check the EA blocks for
6918 E2fsck's symlink sanity checking has been cleaned up. It now checks
6919 the i_size value of fast symlinks, and checks for immutable flags
6920 being set of symlinks, etc.
6922 E2fsck now offers to clear inodes which are special files that have a
6923 non-zero i_blocks or i_size field. (The i_size field check was in the
6924 previous version of the code, but due to a bug it didn't offer to
6925 clear the inode unless i_size and i_size_high were both non-zero.)
6927 E2image can now create "raw" image files, which only contain the
6928 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
6929 debugfs, etc., can be run directly on the raw image file.
6931 Add support for the 64-bit block device patches.
6933 Fixed bugs in creating external journals with a 1k blocksize.
6935 Add initial support for external journals (so long as the external
6936 journal only supports a single filesystem) in e2fsck.
6938 Remove requirement for needing to run fsck on a filesystem after
6939 removing a journal (either internal or external).
6941 The man pages now document how to create and manage external journals.
6943 Speed up the check of an ext3 filesystems by avoiding a needless flush
6944 of all of the superblock and block group descriptors.
6946 Speed up creating an internal journal using tune2fs in the case where
6947 the filesystem has a lot blocks already allocated.
6949 Tune2fs has been fixed to make sure that only error messages go to
6950 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
6952 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
6953 now not set the sparse_super feature. (Addresses Debian bug #108165)
6955 Add support in fsck for the filesystem type "auto".
6957 Fsck -A will not try to interpret device names for filesystems which
6958 have a pass number is 0. (Addresses Debian bug #106696).
6960 Fsck prints a warning message if now valid filesystems are passed to
6961 it. (Addresses Debian Bug #107458.)
6963 E2fsck now gives an explicit warning if there filesystem still has
6964 errors at the end of the run. (Addresses Debian bug #104502)
6966 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
6967 reflects an error. E2fsck will also not run the orphan list if the
6968 filesystem contains errors, since the orphan list might be corrupted.
6970 E2fsck now prints the number of large files when given the -v option.
6972 Fixed minor memory leaks in e2fsck.
6974 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
6977 E2fsprogs 1.22 (June 22, 2001)
6978 ==============================
6980 Fixed a bug in e2fsck's handling of orphan inodes which are special
6981 files (i.e., block/character device files, named FIFO's, etc.).
6983 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
6984 tune2fs to fail at adding a journal to a mounted filesystem.
6986 Fixed a few big-endian bugs in e2fsprogs
6987 * The directory block functions were accidentally reporting
6988 some directories as corrupted when they weren't.
6989 * If e2fsprogs is compiled --disable-swapfs, the C language
6990 equivalents weren't being included for big-endian platforms.
6991 (Fixes Debian bug #101686).
6993 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
6998 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
6999 ioctls, and allow them to be defined for non-i386 platforms.
7001 The uuid.h header file is now protected against multiple inclusions.
7003 E2fsprogs is now being developed using BitKeeper. Changed the test
7004 scripts to deal with BK's stripping CR characters from text files,
7005 and changed the top-level Makefile.in to avoid including BitKeeper
7006 files when generating the source tarball.
7009 E2fsprogs 1.21 (June 15, 2001)
7010 ==============================
7012 Added new configure flags which allow a subset e2fsprogs to be built;
7013 this is most useful for boot floppies, since the resulting shared
7014 libraries and programs are slimmed down by removing features that
7015 aren't necessary for a boot floppy. The new flags that were added
7016 are: --disable-swapfs, which removes support for byte swapping old
7017 legacy PPC/68k filesystems, --disable-debugfs, which removes support
7018 for debugfs from the libext2fs library, --disable-imager, which
7019 removes support for the e2image program, and --disable-resizer, which
7020 removes support for resize2fs.
7022 E2fsck now prints the number of mounts or days elapsed since the last
7023 check when e2fsck is forced to check an otherwise clean filesystem.
7025 Tune2fs now prints an informative message about how often a filesystem
7026 will be checked when adding a journal to the filesystem, to remind the
7027 user that he/she may want to adjust those parameters using tune2fs
7030 Worked around hurd brain-damage which causes e2fsck to sometimes
7031 believe a filesystem is the root filesystem based on device numbers
7032 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
7035 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
7036 erroneous error with the -F option was specified.
7038 Fixed a ext3 recovery bug in the revoke handling; synchronized with
7041 Fixed two bugs in e2fsck's handling of dup block handling, dealing
7042 with relatively uncommon edge cases: a directory with an indirect
7043 block which is claimed by another file, and when the last inode in the
7044 filesystem has blocks claimed by another file.
7046 E2fsck now checks to see if the i_size field of a fast symlink is too
7047 big, and offers to clear the symlink if so.
7049 E2fsck now checks to see if i_size_high of special files is non-zero,
7050 and offers to clear i_size_high.
7052 Fix e2fsck's handling of incompatible journal flags so that the user
7053 has chance to abort, and then has the option to clear out the journal
7054 entirely. (Addresses Debian bug #98527.)
7056 Fixed a bug in fsck which could cause it to core dump if a mix of
7057 standard and non-standard device names are used in /etc/fstab.
7058 (Debian bug #100559)
7060 Fixed a bug in debugfs which caused read errors when copying a file to
7063 The debugfs set_super_value command can now modify the s_lastcheck field.
7065 Fixed a bug in lsattr and chattr which was accidentally introduced in
7066 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
7067 directories correctly because the change modified the layout of struct
7068 dirent to be incompatible with the libe2p shared library.
7070 Cleaned up the mke2fs manual page and included a discussion about why
7071 it's good to periodically check the filesystem even when journalling is
7077 Fix general gcc -Wall complaints.
7079 The types needed by the ext2 header files are now provided by
7080 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
7082 Integers are now preferred to longs when trying to find a 32-bit type
7083 in ext2_types.h. Also, if linux/types.h has already been defined,
7084 don't try to redefine the types.
7086 Fixed make depend script so that it automatically corrects the
7087 pathname cleanups performed by make -M, so I don't have to fix them up
7090 Fixed the d_loaddump test case to be more robust, and not depend on
7093 Removed debugfs's dependence on pread(), which was accidentally
7094 introduced in e2fsprogs 1.20
7096 Fixed a performance bug in the libext2fs's icount routine; the size
7097 estimate of the icount array was incorrectly being calculated.
7099 Removed use of the badblocks compatibility functions in the e2fsprogs
7102 Added paranoia code which protects against strange cases where /etc
7103 isn't on the root filesystem, or if /etc/mtab doesn't exist.
7105 The header file ext2_types.h is now installed.
7107 Autoconf is used to determine when we are on big-endian machines,
7108 instead of doing run-time tests, to save a few bytes of code.
7110 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
7111 functions are no longer inline functions, which saves space and
7112 doesn't really cost any real performance.
7114 The ext2fs library no longer depends on the e2p library. (What need
7115 there was of it --- namely, fsetflags, was coded in-line).
7117 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
7118 when the user is stupid and tries compiling the package using "make
7121 Miscellaneous code cleanups:
7122 * Added missing files from Makefile.in's SRCS file, so that
7123 their dependencies would be properly calculated.
7124 * Removed redundant code
7125 * Fixed comments in code
7126 * Removed no-longer needed argsused #pragma.
7129 E2fsprogs 1.20 (May 20, 2001)
7130 =============================
7132 Add support for replaying the ext3 journal purely in user mode,
7133 including handling the orphaned inode list. Used code contributed by
7134 Andreas Dilger, with bug fixes and the orphaned inode handling done
7137 The mke2fs and tune2fs programs can create or modify a filesystem to
7138 include an ext3 journal. Tune2fs also can be used to remove an ext3
7139 journal from a filesystem.
7141 E2fsck will now check for the existence of a linked list of orphan
7142 inodes in the superblock, and clear those inodes before starting the
7143 rest of the filesystem check (but after the journal playback).
7145 E2fsck now validates the file descriptor passed to the -C option,
7146 which saves against the completion bar getting written to an
7147 unexpected location, such as the disk being checked. (Debian
7148 bug/wishlist #55220)
7150 E2fsck will now bump the filesystem revision number from zero to one
7151 if any of the compatibility bits are set.
7153 Fixed a bug where a badly corrupted directory on a big endian system
7154 could cause e2fsck to die with a bus error. The
7155 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
7156 the ext2 library now does alignment sanity checks on the rec_len field
7157 of the directory entry before using it.
7159 The ext2 library has been enhanced to make tune2fs safe to run on
7160 mounted filesystems. (Users could usually get away with using tune2fs
7161 on mounted filesystems before, but with the advent of ext3 and
7162 journalling, it became important to make tune2fs was *really* safe for
7163 use even when the filesystem being modified is mounted.) E2label is
7164 now implemented by tune2fs using an argv[0] dispatch, so that e2label
7165 is also now safe for use on mounted filesystems.
7167 Added a new program, e2image, which creates a backup of critical ext2
7168 filesystem data structures. The generated image file can be examined
7169 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
7170 the image file to help recover very badly damaged filesystems.
7172 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
7173 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
7174 large file when deciding whether or not the filesystem has large files.
7176 Fixed lsattr and chattr so that they work correctly on large files.
7177 (Fixes Debian bug #72690.)
7179 Removed limitation in get_device_size() which imposed a one terabyte
7180 filesystem limitation. (Most 2.2 kernels still have a signed int
7181 problem which cause 1 TB block device limitation. Fortunately, the
7182 kernel patches to fix this are much easier than fixing the 2TB
7183 limitation in the kernel. :-)
7185 A max_mount_count of zero is now treated as if no mount count were
7186 set. (Previously, no mount count was indicated by using -1, and a
7187 mount count of zero caused e2fsck to always be run.)
7189 Mke2fs supports two new filesystem types largefile and largefile4.
7191 Mke2fs now adds some randomness in s_max_mount_count so that multiple
7192 filesystems won't be all checked at the same time under normal
7195 Fixed bug in the progress bar printing code which could cause e2fsck
7196 to core dump on an illegal filesystem.
7198 Fixed bug in fsck which could allow more than one instance of e2fsck
7199 to be printing a progress bar. (Debian bug #65267)
7201 Fsck using a UUID or a LABEL specifier will work even if devfs is
7202 compiled into the kernel and not mounted. If the pathnames in
7203 /proc/partitions are incorrect, fsck will search /dev for the correct
7204 device (using the new ext2fs_find_block_device library function).
7205 Fsck now also checks the RAID devices first so that they are properly
7206 found when they are in use. Support has also been added to support
7207 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
7209 Fixed a bug in fsck which caused it not deal properly with 16
7210 byte long filesystem labels.
7212 Fsck's -t option has been made a lot more flexible. The semantics for
7213 what happens if a comma-separated list to fsck has been regularized,
7214 and it is now possible to filter what filesystems will get checked
7215 based what is in the filesystem's fstab entry's option field. (Debian
7218 The dumpe2fs program can now print out the group description
7219 information in hex, and also prints the location of the superblock and
7220 block group descriptor for those block groups that have them.
7222 Mke2fs now clears the ext2 superblock before it starts creating a
7223 filesystem, so that the superblock magic number is only written if the
7224 filesystem creation process successfully completes.
7226 The debugfs program's stat command now pretty-prints the blocks used
7227 by an inode so that it's more compact and informative.
7229 The debugfs stats command now uses the same libe2p code (which is used
7230 by dumpe2fs) to print the superblock header information. This is more
7231 complete, and it avoids a bit of code duplication.
7233 Added a new debugfs command, set_super_value (ssv) which allows the
7234 user to set arbitrary superblock fields.
7236 Debugfs was extended to support inode numbers in hex (by prefixing
7237 them with 0x), and so that modify_inode can set the inode generation
7238 number. Also, there is now a new function command called logdump
7239 which will dump an ext3 journal.
7241 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
7244 Debugfs's dump command now stops immediately upon reporting a disk
7245 read error. (Fixed a bug in ext2fs_file_read library routine which
7246 caused debugfs not to stop.) (Debian bug #79163)
7248 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
7249 checked before /etc/mtab is used, since /proc/mounts is more likely to
7252 Added portability fixes for Solaris and Linux/ia64.
7254 Various manual pages were clarified and cleaned up. (Fixed debian
7255 bugs #63442, #67446, and #87216)
7261 The e2fsck message printer now supports %Iu and %Ig, which will print
7262 out the inode's user and group owners, respectively.
7264 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
7265 that no longer dependent on the system having the correct version of
7266 the kernel header files.
7268 Added a new function to libext2, ext2fs_find_block_device(), which
7269 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
7270 device given its device number.
7272 Added a new function to libext2, ext2fs_sync_device, which centralizes
7273 all of the places which might try to use the BLKFLSBUF or FDFLUSH
7274 ioctls (and usually failing to define them since the system header
7275 files don't usually do this for us, and we're trying to avoid usage of
7276 kernel include files now).
7278 Added new utility programs in tests/progs: random_exercise and
7279 hold_inode. They aren't built by default; they're useful for
7280 exercising ext3 filesystem code.
7282 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
7283 the filesystem close functions to only update the superblock, and to
7284 not touch the block group descriptors. Needed by tune2fs when
7285 modifying a mounted filesystem.
7287 Got rid of struct ext2fs_sb and replaced it with the standard struct
7288 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
7289 source (but not binary) compatibility of some users of the ext2
7290 library. Those applications should just simply do a global search and
7291 replace of struct ext2fs_sb with struct ext2_super_block, and include
7292 the new header file <ext2fs/ext2_fs.h> which defines it.
7294 The ino_t type has been renamed ext2_ino_t to protect applications
7295 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
7296 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
7297 unexpected ABI change.
7299 The Makefiles have been reworked so that "make check" can be run from
7300 the top-level Makefile.
7302 Fix general gcc -Wall complaints and removed dead code.
7304 Remove use of NOARGS, because we assume everyone does ANSI C these
7307 Added build-rpm script from sct.
7309 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
7312 New function ext2fs_flush_icache which must be called if the
7313 application program modifies the inode table blocks without going
7314 through ext2fs_write_inode() interface.
7316 New ext2fs_check_mount_point() function, which will return the mount
7317 point of a device if mounted.
7319 The io_channel abstraction now has an optional interface,
7320 io_channel_write_range, which allows specific byte ranges to be
7323 The unix_io IO channel now supports write-through caching, so that
7324 journal creation is more efficient.
7326 Added x86 assembly language routines to support byte swapping, to
7327 reduce executable size.
7329 Fixed bug in the utility program subst so that it's possible to
7330 replace a substitution variable with a zero-length string.
7332 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
7333 slipped into some of the problem number.
7335 E2fsprogs 1.19 (July 13, 2000)
7336 ==============================
7338 Release the resize2fs program since the timeout before it could
7339 be released under the GPL has finally expired.
7341 Add experimental support needed for the ext2 compression patches.
7342 This requires compiling e2fsprogs with the --enable-compression flag
7343 to the configure script.
7345 Added ext3 journalling support. E2fsck will run the journal (if
7346 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
7347 installed as a symlink to e2fsck. Fsck has been taught about ext3,
7348 and treats it the same as ext2 in terms of the progress bar logic.
7349 Dumpe2fs will display the superblock journalling information if the
7350 filesystem has a journal. The ext2 library will now permit opening an
7351 ext3 filesystem with the recovery flag set. This is necessary for
7352 on-line dump's to work correctly, but there may be issues with this
7353 working well since ext3 is much less aggressive about syncing blocks to
7354 the filesystem, since they're safe on the journal.
7356 Tune2fs and e2fsck have been changed to allow the mount_count check to
7357 be disabled by setting max_mount_count to -1. (This was already
7358 supported by the kernel.)
7360 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
7361 are used for ext3 as well.
7363 Added internationalization support for e2fsprogs; must be enabled
7364 by passing --enable-nls to configure.
7366 Always use the provided ext2fs header files to insulate ourselves from
7367 kernel version changes. Which include files are used by e2fsprogs
7368 have also been cleaned up to improve portability.
7370 Limit the number of times that e2fsck updates the progress bar so that
7371 people who are booting using a 9600 baud console don't get swamped by
7374 Improved the loop detection algorithm in e2sck's pass #3 so that it is
7375 much, much faster for large filesystems with a large number of
7378 The memory footprint for e2fsck is now slightly smaller than before.
7380 E2fsck now checks if special devices have a non-zero size, and offers
7381 to clear the size field if it finds such an inode.
7383 E2fsck now checks if special devices have the append-only flag set,
7384 and offers to clear the inode.
7386 E2fsck now properly handles some "should never fail" cases during a
7387 bitmap copy in pass5.
7389 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
7391 E2fsck now calculates the correct location of the backup superblock in
7392 the case of filesystem blocksizes > 1k.
7394 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
7395 which normally didn't cause problems under most filesystem parameters,
7396 but could cause a valid superblock to be rejected in extreme cases.
7397 Other checks for validating superblock values were made more
7400 Added non-destructive write testing to the badblocks program, courtesy
7401 of David Beattie. The badblocks also now has an option to input the
7402 current set of bad blocks, so that known bad blocks are skipped to
7403 speed up the badblocks test. There is also a persistent rescan
7404 feature which causes badblocks to run until it has completed some
7405 number of passes without discovering any new bad blocks.
7407 Badblocks now checks to see if the device is mounted and refuses to do
7408 the tests involving writing to the device if it is mounted. Also,
7409 badblocks now allows the number of blocks to be checked to be
7410 defaulted to the size of the partition.
7412 Fixed a bug in fsck which didn't allow non-root users to be able to
7413 check filesystems if there were any LABEL= or UUID= entries in
7416 The Hurd doesn't support the filetype filesystem feature. The mke2fs
7417 program now makes sure that for the Hurd, the filetype feature is
7418 turned off. E2fsck will check to see if the filetype feature is
7419 turned on for Hurd filesystems, and offer to turn off the feature.
7421 Mke2fs now has a safety check to make sure the number of blocks do not
7422 exceed 32 bits even on a 64 bit platform.
7424 Really fixed a bug in fsck to allow "fsck -As" to run interactive
7425 fsck's. (For those people who like to do interactive fsck's in the
7428 Debugfs has a few new features: the rdump command, which will do a
7429 recursive dump of a directory and all of its contents, and the lcd
7430 command which does a local chdir (much like the ftp command of the
7431 same name). In addition, the debugfs program and the open_filesystem
7432 command now takes three new options: -b and -s, which allows the
7433 blocksize and superblock location to be specified, and the -c option
7434 which is used in catastrophic situations where the block group
7435 descriptors are corrupt. If the -c option is specified, debugfs will
7436 skip trying to read in the block and inode bitmaps.
7438 Debugfs's lsdel command was fixed to handle bad blocks in the inode
7441 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
7444 General improvements in error messages
7446 - Mke2fs prints a sane error message if the partition size is zero
7447 (usually because the partition table wasn't reread by the
7448 kernel due to the partition being busy), instead of "invalid
7449 argument passed to ext2 library while initializing superblock".
7451 - Fsck now prints more self-explanatory message if an invalid UUID=
7452 or LABEL= specification is passed to it.
7454 UUID library changed to use the LGPL.
7456 Fixed a bug in the UUID library where very rapid calls to the
7457 time-based UUID generator could cause duplicate UUID's to be returned.
7458 This was not a problem for e2fsprogs, but it could be a problem for
7459 other users of the library.
7461 Make the UUID library more robust in the face of missing or an
7462 improper /dev/urandom or /dev/random files.
7464 Added some random portability fixes for Solaris.
7466 Some minor man page updates.
7468 Fixed a memory leak in the ss library.
7474 We now try to use lseek64 and open64 from the LFS if possible.
7476 The 3rd parameter in e2p's print_flags is now a flags word, instead of
7479 The mark and unmark bitmap functions now return the previous state of
7480 the bit that was being changed, which is useful for some speed
7483 The following functions have been added to enhance the badblocks list
7484 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
7485 ext2fs_badblocks_equal.
7487 The ext2 header files now have the latest journalling fields to the
7490 The ext2fs_mkdir function in libext2fs now properly backs out of error
7491 conditions robustly.
7493 Cleaned up makefiles:
7494 - to cleanly compile with the -j flag.
7495 - so distclean removes all generated files.
7496 - so in case of an error while installing header files, the make aborts.
7498 Fix test_script so that it works correctly when compiling in the
7501 The random UUID generation routine has been made slightly better in
7502 the case where /dev/random doesn't exist. (Use of randomly-based UUID
7503 is still not recommended if /dev/random doesn't exist, however; it's
7504 better to use the time/ethernet MAC address UUID in this case.)
7506 Clean up the build process so it's more friendly in case of missing
7509 The ext2fs header file can now be #include'd into C++ programs.
7511 The e2p.h header file is now installed.
7513 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
7517 E2fsprogs 1.18 (November 10, 1999)
7518 ==================================
7520 Fix a core dumping bug in e2fsck if an imagic inode is present or
7521 (more rarely) if the filesystem is badly corrupted enough that e2fsck
7522 has to restart pass 1 processing. E2fsck now closes the filesystem
7523 before freeing a large number of its data structures, so in the case
7524 of future memory faults, at least the fixed filesystem will be fully
7527 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
7528 imagic inode, it will offer to clear the imagic flag.
7530 E2fsck will now offer to clear the immutable flag on special files
7531 (device/socket/fifos) when running it in non-preen mode.
7533 E2fsck will now set the filetype when creating /lost+found, and when
7534 connected orphaned inodes to /lost+found.
7536 Debugfs's ncheck and icheck commands now handles the case where there
7537 are bad blocks in the inode table without bombing out.
7539 The badblocks list processing code has been made more efficiently for
7540 appending a large number of (ordered) badblocks to the badblocks list.
7542 Some minor man page updates.
7544 Fsck now allows interactive e2fsck's when using fsck -As (not a common
7545 mode, but some people like to do this in boot scripts for silly reasons).
7550 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
7551 with the problem code convention.
7553 The badblocks list regression test program has been updated to work
7554 with previously made API name changes.
7556 The ext2fs_free() command now uses the new badblocks API to avoid
7557 using the compatibility layer.
7559 Added new regression test cases; the run_e2fsck test script now
7560 supports the ability for a test case to run a preparatory command
7561 before running e2fsck.
7563 E2fsprogs 1.17 (October 26, 1999)
7564 =================================
7566 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
7569 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
7570 thus potentially causing problems if a binary UUID contained a NULL
7573 E2fsck now uses stricter checks for directory entries in pass 2:
7574 zero-length filenames are not allowed; neither are 8 byte long
7577 The debugfs "dirty" command now clears the filesystem valid bit.
7578 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
7579 bit in the in-core superblock image. The new functionality is more
7580 what the user expects, and is more useful.)
7582 Added a debugging hook to test parallel fsck; if the environment
7583 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
7584 will be checked in parallel when they normally would not be.
7589 Fixed some #ifdef's for compilation under the Hurd OS.
7591 Fixed minor W2K compatibility problems.
7593 Fixed some miscellaneous GCC warnings.
7596 E2fsprogs 1.16 (October 22, 1999)
7597 =================================
7599 Fixed a race condition bug in fsck; when printing a progress bar, if
7600 checking multiple filesystems in parallel, it was possible for fsck to
7601 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
7602 handler, which would cause it to terminate with a signal 10.
7604 E2fsck now properly handles filesystems that have the
7605 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
7606 filesystem into using or not using FILETYPE feature.
7608 E2fsck now properly handles filesystems that have the IMAGIC feature
7609 turned on (this is used on Linux AFS servers).
7611 The mke2fs program now creates filesystems that have the filetype and
7612 sparse_superblock features enabled by default, unless it is run on a
7613 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
7614 so there is now a new flag -O which allows the user to specify with
7615 which features she would like to create the filesystem; "mke2fs -O
7616 none" will create a filesystem compatible with 2.0 kernels.
7618 The tune2fs program now has a -O option which allows the user to set
7619 and reset "safe" filesystem features. Currently, the only ones which
7620 allows to be modified are the filetype and sparse_superblock features.
7621 Note setting or clearing either feature will require running e2fsck on
7622 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
7623 requires that there is enough free space on the filesystem for the
7624 extra superblocks which will be created by e2fsck.)
7626 Debugfs can now set and print filesystem features in the superblock
7627 using the "features" command. Dumpe2fs will print out the complete
7628 set of features when listing the superblock.
7630 Dumpe2fs has new options -f (force) and -h (header-only).
7632 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
7633 message to come up. This could happen when decrementing or
7634 incrementing a link count could result in an overflow.
7636 Fixed a bug in e2fsck where the block count on the lost+found
7637 directory would not be properly incremented when the directory was
7638 expanded to the point where an indirect block needed to be allocated.
7640 E2fsck now makes some additional sanity checks on the superblock to
7641 avoid crashing or giving a memory allocation error if some of the
7642 values in the superblock are unreasonable (but the superblock otherwise
7645 Fixed a bug in e2fsck where a very badly corrupted filesystem might
7646 require two passes to completely fix the filesystem. This happened if
7647 an inode claimed blocks that was part of the filesystem metadata
7648 (typically, when garbage was written into an inode table or indirect
7649 block, since this kind of filesystem corruption normally doesn't
7652 On the Alpha, glibc declares st_flags although it isn't actually used;
7653 the configure script was improved to detect this case so that
7654 e2fsprogs can avoid using the non-functional stat field.
7656 The manual pages were updated to use a more consistent formatting
7657 style consistent with standard Unix man pages. Mke2fs's man page
7658 added documentation for a few previously undocumented options.
7660 Fixed minor display bugs in tune2fs and mke2fs.
7665 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
7667 Added features to parse and print feature strings into the e2p library.
7668 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
7670 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
7671 whose directory entries contain proper filetype information if the
7672 filesystem supports it.
7674 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
7675 the directory entry filetype information. This is used to set the
7676 directory entry filetype information if the filesystem supports it.
7678 Fixed a bug in ext2fs_expand_dir() where the block count in a
7679 directory's inode would not be properly incremented when the directory
7680 was expanded to the point where an indirect block needed to be
7684 E2fsprogs 1.15 (July 18, 1999)
7685 ==============================
7687 Add configuration checks so that e2fsprogs will compile cleanly on
7688 Linux 2.3 kernels that have renamed i_version to i_generation.
7690 E2fsck now prints a progress/completion bar (and not just a simple
7691 spinner) if the -C0 option is requested or if it receives a SIGUSR1
7692 signal. Fsck will automatically manage the (potentially multiple)
7693 e2fsck processes to print completion bars if it is given a -C option,
7694 with the right thing happening if multiple filesystems are being
7695 checked in parallel.
7697 Mke2fs now has better automatic heuristics to determine the filesystem
7698 parameters to be used for a particular filesystem. Added a new option
7699 -T which allows the user to specify how the filesystem is to be used,
7700 which helps mke2fs do a better job selecting the filesystem parameters.
7702 Mke2fs now creates revision 1 filesystems by default, and with the
7703 sparse superblock feature enabled. The sparse superblock feature is
7704 not understood by Linux 2.0 kernels, so they will only allow read-only
7705 mounts of filesystems with this sparse superblocks.
7707 Fix bug where if /dev/null couldn't be opened (should never happen),
7708 e2fsck would hang in a tight loop.
7710 Make e2fsck handle the case where /lost+found isn't a directory.
7712 E2fsck now uses mallinfo if it exists to get accurate statistics about
7715 Fix bug in e2fsck where it wouldn't check to see if a disconnected
7716 inode had any problems before connecting it to /lost+found.
7718 Add check to e2fsck so it makes sure that total number of inodes in
7719 the filesystem is a sane number.
7721 Fix fencepost error when clearing an the end of the block bitmap which
7722 caused the last block in the bitmap not to get cleared.
7724 Cleaned up a number of messages in e2fsck:
7725 * The message "Group's #'s copy of the group descriptor..."
7726 was fixed so that the correct number would be displayed.
7727 * Added missing space in the "disk write-protected" error message
7728 * Cleaned up the error message printed when a non-interactive
7729 e2fsck needs to abort a check because the filesystem
7730 appears to be mounted.
7732 Added a new command-line utility, uuidgen, which will create and print
7735 Make debugfs's icheck command more robust by checking to make sure an
7736 inode has valid blocks before iterating over the inode's blocks.
7738 UUID generation now uses a random-based scheme whenever possible to
7739 prevent potential privacy problems.
7741 Man pages for all of the UUID functions in the library were added.
7743 Fixed bug in fsck so it won't coredump if a filesystem not in
7744 /etc/fstab is given to it.
7746 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
7747 that most of the other mount utilities understands.
7749 Mke2fs will make a filesystem even if it appears mounted if the force
7752 Dumpe2fs has new command-line options which allow a filesystem expert
7753 to specify the superblock and blocksize when opening a filesystem.
7754 This is mainly useful when examining the remains of a toasted
7757 The badblocks program has been updated to display correctly on disks
7758 with large block numbers.
7760 The badblocks program no longer gives spurious errors when errors
7761 occur on non-block boundaries, which is common if the blocksize is
7764 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
7765 MKE2FS_SYNC environment variable is set. This is to work around a VM
7766 bug in the 2.0 kernel. I've heard a report that a RAID user was able
7767 to trigger it even using a 2.2 kernel, but hopefully it will not be
7768 needed for most Linux 2.2 users.
7770 Fixed miscellaneous documentation and man pages.
7775 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
7776 in e2fsck's pass1.c really should have been static.
7778 The return value of the uuid_compare() function was changed to make it
7779 match with the conventions used by strcmp, memcmp, and Paul Leach's
7780 UUID sample document.
7782 The "make depend" process has now been made more automated; it now
7783 automatically word-wraps the dependencies, and only replaces source
7784 Makefile.in if there has been a change in the dependencies. Also, a
7785 top-level "make depend" now recurses through all the subdirectories
7788 The Makefile in .../util has been changed so that subst is built using
7789 the native C compiler during a cross-compilation, since the subst
7790 program is only used during the build process. Also add an explicit
7791 rule to build util/subst by cd'ing to the correct directory and
7794 The man directories are defined in terms mandir, so that the configure
7795 script can override the location of the manual pages.
7797 The config files have been updated to recognize new machine types for
7798 both the i386 and alpha families.
7800 Fsck has been modified so that it will accurately create an
7801 fsck_instance even when the noexecute flag is set. This allows for
7802 accurate debugging of the fsck pass structure. Also, when the verbose
7803 flag is given twice, fsck will print debugging information about when
7804 fsck is waiting for jobs to finish.
7807 E2fsprogs 1.14 (January 9, 1999)
7808 ================================
7810 Fix the fstab parsing code so that it can handle blank lines and
7811 comment characters. Also, missing pass numbers need to be treated as
7814 Fixed a bug in e2fsck where under some circumstances (when e2fsck
7815 needs to restart processing after fixing an egregious inconsistency)
7816 it would try to access already freed memory.
7818 E2fsck now prints non-printable characters in directory entries and
7819 pathnames using '^' and 'M-' notation.
7821 Fixed chattr so that it will ignore symbolic links when doing
7822 recursive descent traversals. For both chattr and lsattr, no longer
7823 print the version string unless the -V option is given.
7825 Allow the system administrator to directly specify the number of
7826 inodes desired in the filesystem, for some special cases where this is
7829 Fix portability problems so that e2fsprogs can be compiled under Linux
7830 1.2 systems and Solaris systems.
7832 Update the config.guess file with a more recent version that will
7833 identify newer Linux platforms.
7838 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
7839 an inode number of zero is passed to them.
7841 E2fsprogs 1.13 (December 15, 1998)
7842 ==================================
7844 Fixed a bug in debugfs where an error messages weren't getting printed
7845 when the ext2 library routines to read inodes returned errors in the
7846 stat, cmri and rm commands.
7848 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
7849 provided, it won't create an inode table smaller than the minimum
7850 number of inodes required for a proper ext2 filesystem.
7852 Fsck now parses the /etc/fstab file directly (instead of using
7853 getmntent()), so that it can distinguish between a missing pass number
7854 field and pass number field of zero. This caused problems for
7855 diskless workstations where all of the filesystems in /etc/fstab have
7856 an explicit pass number of zero, and fsck could not distinguish this
7857 from a /etc/fstab file with missing pass numbers.
7859 E2fsck will create a /lost+found directory if there isn't one in the
7860 filesystem, since it's safer to create the lost+found directory before
7863 Fixed e2fsck so that it would detect bogus immutable inodes which
7864 happen to be sockets and FIFO files, and offer to clear them.
7866 If a filesystem has multiple reasons why it needs to be checked, and
7867 one of the reasons is that it is uncleanly mounted, e2fsck will print
7868 that as the reason why the filesystem is being checked.
7870 Cleaned up the output routines of mke2fs so that it doesn't overflow
7871 an 80 column display when formatting really big filesystems.
7873 Added a sanity check to e2fsck to make sure that file descriptors 0,
7874 1, 2 are open before opening the hard disk. This avoids a problem
7875 where a broken program might exec e2fsck with those file descriptors
7876 closed, which would cause disastrous results if the kernel returns a
7877 file descriptor for the block device which is also used by FILE *
7880 Fixed up the e2fsck progress reporting functions so that the values
7881 reliably reach 100% at the completion of all of the e2fsck passes.
7883 Fixed minor documentation bugs in man pages and usage messages.
7888 Fixed a number of lint warnings in the ext2fs library and potential
7889 portability problems from other OS's header files that might define
7890 CPP macros for names like "max" and "min".
7892 ext2fs_badblocks_list_add() has been made more efficient when it needs
7893 to grow the bad blocks list.
7895 Fixed a bug in e2fsck which caused it to dereference a freed pointer
7896 just before exiting.
7898 Fixed the substitution process for generating the mk_cmds and compile_et
7899 scripts so that they will work outside of the build tree.
7901 Add sanity check to e2fsck so that if an internal routine
7902 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
7903 and causing a core dump. This should never happen, but...
7905 E2fsprogs 1.12 (July 9, 1998)
7906 ==================================
7908 E2fsprogs now works with glibc (at least with the version shipped with
7909 RedHat 5.0). The ext2fs_llseek() function should now work even with
7910 i386 ELF shared libraries and if llseek() is not present. We also
7911 explicitly do a configure test to see if (a) llseek is in libc, and
7912 (b) if llseek is declared in the system header files. (See standard
7913 complaints about libc developers don't understand the concept of
7914 compatibility with previous versions of libc.)
7916 The ext2fs library now writes out the block group number in each of
7917 the superblock copies. This makes it easier to automatically
7918 determine the starting block group of the filesystem when the block
7919 group information is trashed.
7921 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
7922 which means that e2fsprogs will ignore the high 8 bits of the
7923 directory entry's name_len field, so that it can be used for other
7926 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
7927 E2fsprogs will now support filesystems with 64-bit sized files.
7929 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
7931 Added new program "e2label", contributed by Andries Brouwer. E2label
7932 provides an easy-to-use interface to modify the filesystem label.
7934 Fixed bug so that lsattr -v works instead of producing a core dump.
7936 Fixed a minor bug in mke2fs so that all groups with bad superblock
7937 backup blocks are printed (not just the first one).
7939 Mke2fs will check the size of the device, and if the user specifies a
7940 filesystem size larger than the apparent size of the device it will
7941 print a warning message and ask if the user wants to proceed.
7943 E2fsck has a new option -C, which sends completion information to the
7944 specified file descriptor. For the most part, this is intended for
7945 programs to use, although -C 0 will print a spinning character to the
7946 stdout device, which may be useful for users who want to see something
7947 happening while e2fsck goes about its business.
7949 Fixed a bug in e2fsck which could cause a core dump when it needs to
7950 expand the /lost+found directory, and sometimes the bitmaps haven't
7951 been merged in. Also fixed a related bug where ext2fs_write_dir_block
7952 was used to write out a non-directory block. (Which would be bad on a
7953 non-Intel platform with byte swapping going on.)
7955 Fixed bug in e2fsck where it would print a "programming error" message
7956 instead of correctly identifying where a bad block was in used when
7957 the bad block was in a non-primary superblock or block group
7958 descriptor. Also fixed a related bug when sparse superblocks are in
7959 use and there is a bad block where a superblock or block group
7960 descriptor would have been in a group that doesn't include a
7963 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
7964 the block group descriptor table is corrupt, it was possible to try to
7965 allocate a huge array, fail, and then abort e2fsck.
7966 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
7967 and substitutes reasonable values if the descriptors are obviously bogus.
7969 If e2fsck finds a device file which has the immutable flag set and the
7970 i_blocks beyond the normal device number are non-zero, e2fsck will
7971 offer to remove it, since it's probably caused by garbage in the inode
7974 When opening a filesystem, e2fsck specially checks for the EROFS error
7975 code, and prints a specific error message to the user which is more
7978 If the filesystem revision is too high, change the e2fsck to print
7979 that this is either because e2fsck is out of date, or because the
7980 superblock is corrupt.
7982 E2fsck now checks for directories that have duplicate '.' and '..'
7983 entries, and fixes this corruption.
7985 E2fsck no longer forces a sync of the filesystem (with attendant sleep
7986 calls) at all times. The ext2fs_flush() function now performs a sync
7987 only if it needed to write data blocks to disk.
7989 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
7990 certain errors would not be properly reported.
7992 Updated and expanded a few points in the man pages which users
7993 complained weren't explicit enough.
7995 Added special case byte-swapping code if compiling on the PowerPC, to
7996 accommodate the strange big-endian variant of the ext2 filesystem that
7997 was previously used on the PowerPC port.
8003 Removed C++ keywords from the ext2fs libraries so that it could be
8006 E2fsck's internal organization has now been massively reorganized so
8007 that pass*.c don't have any printf statements. Instead, all problems
8008 are reported through the fix_problem() abstraction interface. E2fsck
8009 has also been revamped so that it can be called as a library from a
8012 Added new fileio primitives in libext2fs for reading and writing
8013 files on an unmounted ext2 filesystem. This interface is now used by
8016 Added a new libext2fs function for mapping logical block numbers of
8017 a file to a physical block number.
8019 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
8020 a block, zeros it, and updates the filesystem accounting records
8023 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
8024 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
8026 The libext2fs functions now use a set of memory allocation wrapper
8027 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
8028 instead of malloc, free, and resize. This makes it easier for us to
8029 be ported to strange environments where malloc, et. al. aren't
8030 necessarily available.
8032 Change the libext2fs function to return ext2-specific error codes
8033 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
8034 and depending on the existence of system error codes (such as EEXIST
8037 Renamed io.h to ext2_io.h to avoid collision with other OS's header
8040 Add protection against ext2_io.h and ext2fs.h being included multiple
8043 The types used for memory lengths, etc. have been made more portable.
8044 In general, the code has been made 16-bit safe. Added Mark
8045 Habersack's contributed DOS disk i/o routines.
8047 Miscellaneous portability fixes, including not depending on char's
8050 The io_channel structure has a new element, app_data, which is
8051 initialized by the ext2fs routines to contain a copy of the filesystem
8054 ext2fs_check_directory()'s callback function may now return the error
8055 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
8056 really do the checking, despite the presence of the callback function.
8059 E2fsprogs 1.11 (June 17, 1997)
8060 ==============================
8062 Fixed e2fsck to detect (previously ignored) conflicts between the
8063 superblock or block group descriptors and block bitmaps, inode
8064 bitmaps, and inode tables.
8066 Fixed bug in e2fsck so that when the message printed out when a block
8067 or inode bitmap conflicts with other data, it has the correct group
8070 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
8071 to badblocks. This meant that not all of the filesystem was being
8072 tested for bad blocks!
8074 Fixed an array boundary overrun case which cropped up in
8075 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
8078 Adjusted the number of columns printed by mke2fs when displaying the
8079 superblock backups to avoid running over 80 columns when making a
8080 really big filesystem.
8082 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
8083 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
8084 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
8089 Fixed install rule in lib/ss so that ss_err.h is actually getting
8092 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
8093 passed back to the caller.
8095 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
8096 setting the current inode number (which meant this function wasn't
8099 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
8100 blocks in the bitmap when increasing the size of the bitmap.
8102 Changed the initial number of blocks allocated by ext2fs_init_dblist()
8103 to be more realistic.
8105 Added a new function ext2fs_allocate_group_table, which sets up the
8106 group descriptor information (and allocates inode and block bitmaps,
8107 and inode tables for a particular group). The function was created by
8108 factoring out code form ext2fs_allocate_tables().
8110 Added a new function ext2fs_move_blocks which takes a bitmap of the
8111 blocks to be moved, and moves them to another location on the
8114 Make the unix_io channel's io_channel_flush implementation calls sync()
8115 to to flush the kernel buffers to disk.
8117 Added a new function ext2fs_dblist_count returns the number of
8118 directory blocks in dblist.
8121 E2fsprogs 1.10 (April 24, 1997)
8122 ===============================
8124 Mke2fs once again defaults to creating revision #0 filesystems, since
8125 people were complaining about breaking compatibility with 1.2 kernels.
8126 Warning messages were added to the mke2fs and tune2fs man pages that
8127 the sparse superblock option isn't supported by most kernels yet (1.2
8128 and 2.0 both don't support parse superblocks.)
8130 Added new flag to mke2fs, -R <raid options>, which allows the user to
8131 tell mke2fs about the RAID configuration of the filesystem. Currently
8132 the only supported raid option is "stride" which specifies the width
8135 Fixed bug in e2fsck where pass1b would bomb out if there were any
8136 blocks marked bad in the inode table.
8138 Fixed rare bug in mke2fs where if the user had a very unlucky number
8139 of blocks in a filesystem (probability less than .002) the resulting
8140 filesystem would be corrupt in the last block group.
8142 Fixed bug where if e2fsck tried to allocate a block to fix a
8143 filesystem corruption problem and the filesystem had no free blocks,
8144 ext2fs_new_block() would loop forever.
8146 The configure script now checks explicitly to see if "-static" works,
8147 since that can't be assumed to be true --- RedHat doesn't install
8148 libc-static by default.
8150 Fixed bug in libext2's block iterator functions where under some
8151 circumstances, file with holes would cause the bcount parameter to the
8152 callback function to be incorrect. This bug didn't affect any of
8153 e2fsprogs programs, but it was discovered by Paul Mackerras, the
8154 author of the PPC boot loader.
8156 Removed use of static variables to store the inode cache in libext2fs.
8157 This caused problems if more than one filesystem was accessed via
8158 libext2fs (static variables in libraries are generally a bad idea).
8159 Again, this didn't affect e2fsprogs programs, but it was discovered by
8162 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
8163 will compile cleanly with 1.2.13 kernels (even with a.out shared
8169 Added new functions to duplicate an ext2 filesystem handle, and its
8170 associated substructure. New functions: ext2fs_dup_handle(),
8171 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
8172 Other structures, such as the io_channel and the inode_cache, now have
8173 a ref count so that they only get freed when they are no longer used
8174 by any filesystem handle. (These functions were added as part of the
8175 development effort for an ext2 resizer).
8177 E2fsprogs 1.09 (April 14, 1997)
8178 ===============================
8180 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
8181 accidentally introduced in the 1.08 release. The overhead calculation
8182 was accidentally removed, which caused ext2fs_initialize() to not
8183 notice when the filesystem size needed to be adjusted down because
8184 there wasn't enough space in the last block group.
8186 Fixed bug in version parsing library routine; it was always parsing
8187 the library version string, instead of using the passed-in string.
8189 Clarified chattr man page.
8191 E2fsprogs 1.08 (April 10, 1997)
8192 ===============================
8194 E2fsck 1.07 was very slow when checking very large filesystems with a
8195 lot of files that had hard links (i.e., news spools). This was fixed
8196 by seriously revamping the icount abstraction. Added a formal test
8197 suite for the icount abstraction.
8199 Debugfs now has a "-l" option to the "ls" command, which lists the
8200 inode number, permissions, owner, group, size, and name of the files
8203 Fix a bug in e2fsck where when a directory had its blocks moved to
8204 another location during the pass 1b processing, the directory block
8205 list wasn't updated, so pass 2 wouldn't check (and correct) the
8206 correct directory block.
8208 E2fsck will now treat inodes which contain blocks which are claimed by
8209 the filesystem metadata by treating them as multiply claimed blocks.
8210 This way, the data in those blocks can be copied to a new block during
8211 the pass 1b--1d processing.
8213 E2fsck will attempt to determine the correct superblock number and
8214 display it in the diagnostic and warning messages if possible.
8216 Add support for a new (incompatible) feature, "sparse_super". This
8217 feature reduces the number of blocks which contain copies of backup
8218 superblocks and block group descriptors. (It is only an incompatible
8219 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
8220 support a new -s option; e2fsck will recognize filesystems built with
8221 this feature turned on.
8223 E2fsck now checks the library to make sure is the correct version,
8224 using new library functions. (This helps to diagnose incorrectly
8225 installed e2fsprogs distributions.)
8227 Dumpe2fs now prints more information; its now prints the the
8228 filesystem revision number, the filesystem sparse_super feature (if
8229 present), the block ranges for each block group, and the offset from
8230 the beginning of the block group.
8232 Mke2fs now distributes the inode and block bitmap blok so that the
8233 won't be concentrated in one or two disks in RAID/striping setups.
8234 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
8235 choose the largest blocks per group that be chosen. (For 2k blocks,
8236 you can have up to 16384 blocks/group; for 4k blocks, you can have up
8237 to 32768 blocks/group.) Previously mke2fs would not allow
8238 specification of more than 8192 blocks per group, even if you were
8239 using a 2k or 4k block group.
8244 Added a new function ext2fs_create_icount2() which takes a "hint"
8245 argument. This hint argument presets the icount array with the list
8246 of inodes which actually need to be in the icount array. This really
8247 helps to speed up e2fsck.
8249 Added a new function ext2fs_icount_validate() which checks the rep
8250 invariant for the icount structure. This is used mostly for testing.
8252 The error message given when a bad inode number is passed to
8253 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
8254 EXT2FS_UNMARK_ERROR).
8256 Added a new function ext2fs_set_dir_block which sets the block of a
8257 dblist entry, given the directory inode and blockcnt.
8259 Added a new function ext2fs_get_library_version() which returns the
8260 current library version, and ext2fs_parse_version_string() which
8261 returns a version number based on a e2fsprogs version string.
8263 The icount functions will return EINVAL if the passed in inode number
8266 E2fsprogs 1.07 (March 9, 1997)
8267 ==============================
8269 E2fsck is now uses much less memory when checking really large
8270 filesystems (or rather, filesystems with a large number of inodes).
8271 Previously a filesystem with 1 million inodes required 4 megabytes of
8272 memory to store inode count statistics; that storage requirement has
8273 now been reduced to roughly half a megabyte.
8275 E2fsck can now properly deal with bad blocks appearing inside the
8276 inode table. Instead of trying to relocate the inode table (which
8277 often failed because there wasn't enough space), the inodes in the bad
8278 block are marked as in use.
8280 E2fsck will automatically try to use the backup superblocks if the
8281 primary superblocks have a bad magic number or have missing meta-data
8282 blocks (or meta-data blocks which are out of range).
8284 E2fsck's pass 3 has been made more efficient; most noticeable on
8285 filesystems with a very large number of directories.
8287 Completely revamped e2fsck's system of printing problem reports. It
8288 is now table driven, to make them more easily customizable and
8289 extendable. Error messages which can be printed out during preen mode
8290 are now one line long.
8292 Fixed e2fsck's filesystem swapping code so that it won't try to swap
8293 fast symbolic links or deleted files.
8295 Fixed e2fsck core dumping when fixing a filesystem which has no
8296 directories (not even a root directory).
8298 Added a check to e2fsck to make sure that the length of every
8299 directory entry is a multiple of 4 (since the kernel complains if it
8302 Added a check to e2fsck to make sure that a directory entry isn't a
8303 link to the root directory, since that isn't allowed.
8305 Added a check to e2fsck to now make sure the '.' and '..' directory
8306 entries are null terminated, since the 2.0 kernel requires it.
8308 Added check to write_bitmaps() to make sure the superblock doesn't get
8309 trashed if the inode or block bitmap is marked as being block zero.
8311 Added checking of the new feature set fields in the superblock, to
8312 avoid dealing with new filesystem features that this package wasn't
8315 Fixed a fencepost error in ext2fs_new_block() which would occasionally
8316 try to allocate a block beyond the end of a filesystem.
8318 When the UUID library picks a random IEEE 802 address (because it
8319 can't find one from a network card), it sets the multicast bit, to
8320 avoid conflicting with a legitimate IEEE 802 address.
8322 Mke2fs now sets the root directory's owner to be the real uid of the
8323 user running mke2fs. If the real uid is non-zero, it also sets
8324 the group ownership of the root directory to be the real group-id of
8325 the user running mke2fs.
8327 Mke2fs now has more intelligent error checking when it is given a
8328 non-existent device.
8330 When badblocks is given the -vv option, it now updates the block that
8331 it is currently testing on every block.
8333 Fixed a bug in fsck where it wouldn't modify the PATH environment
8334 currently correctly if PATH wasn't already set.
8336 Shared libraries now built with dependencies. This allows the shared
8337 library files to be used with dlopen(); it also makes the transition
8338 to libc 6 easier, since ld.so can tell which libc a particular shared
8339 library expects to use.
8344 Added new abstraction (defined in dblist.c) for maintaining a list of
8345 blocks which belongs to directories. This is used in e2fsck and other
8346 programs which need to iterate over all directories.
8348 Added new functions which test to see if a contiguous range of blocks
8349 (or inodes) are available. (ext2fs_*_bitmap_range).
8351 Added new function (ext2_inode_has_valid_blocks) which returns true if
8352 an inode has valid blocks. (moved from e2fsck code).
8354 Added new function (ext2fs_allocate_tables) which allocates the
8355 meta-data blocks as part of initializing a filesystem. (moved from
8358 Added a new I/O manager for testing purposes. It will either allow a
8359 program to intercept I/O requests, or print debugging messages to
8360 trace the activity of a program using the I/O manager.
8362 The badblocks_list functions now store the bad blocks in a sorted
8363 order, and use a binary search to speed up badblocks_list_test.
8365 The inode scan function ext2fs_get_next_inode() may now return a soft
8366 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
8367 those cases where part of an inode table is missing or there is a bad
8368 block in the inode table.
8370 Added a new function (ext2fs_block_iterate2) which adds new arguments to
8371 the callback function to return a pointer (block and offset) to the
8372 reference of the block.
8374 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
8375 application to jump to a particular block group while doing an inode
8378 The badblocks list functions were renamed from badblocks_* to
8379 ext2fs_badblocks_*. Backwards compatibility functions are available
8380 for now, but programs should be modified to use the new interface.
8382 Some of the library functions were reorganized into separate files to
8383 reduce the size of some programs which statically link against the
8386 Put in some miscellaneous fixes for the Alpha platform.
8389 E2fsprogs 1.06 (October 7, 1996)
8390 ================================
8392 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
8393 smash the backup copies in ext2fs_close(). (The problem was that when
8394 e2fsck -p discovered the problem, while it was closing the filesystem
8395 and exiting, it was also blowing away the backup superblocks on the
8396 disk, which was less than friendly.) We now make it the case that we
8397 only write out the backup superblock and the back block descriptors if
8398 the filesystem is completely free from problems.
8400 Fixed a bug in block_interate in the lib/ext2fs library which caused
8401 e2fsck to fail on GNU Hurd-created filesystems.
8403 Add support for Linux/FT's bootloader, which actually uses
8404 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
8407 Add support for the "A" (no atime update) attribute. (Note: this
8408 attribute is not yet in production kernels.)
8410 The test suite is not automatically run when doing a "make all" from
8411 the top level directory. Users should manually run "make check" if
8412 they wish to run the test suite.
8414 Upon a preenhalt(), make the printed message more explicit that
8415 running e2fsck "MANUALLY" means without the -p or -a options.
8417 In e2fsck, if a disconnected inode is zero-length, offer to clear it
8418 instead of offering to connect it to lost+found.
8420 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
8421 e2fsck to be run over it, change e2fsck to explicitly display this
8424 For dumpe2fs and e2fsck, cause the -V option to print out which
8425 version of the ext2fs library is actually getting used. (This will
8426 help detect mismatches of using a 1.06 utility with a 1.05 library,
8432 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
8433 the naming convention.
8435 In ext2fs_initialize(), make sure the description for the inode bitmap
8436 is correctly initialize.
8438 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
8440 E2fsprogs 1.05 (September 7, 1996)
8441 ==================================
8443 Add support for new fields in the ext2 superblock --- volume name,
8444 volume UUID, and last mounted field. Dumpe2fs displays these fields,
8445 tune2fs and mke2fs allows you to set them. E2fsck will automatically
8446 generate a UUID for those volumes that don't have them.
8448 Put in support for e2fsck to recognize HURD specific ext2 features ---
8449 most notably, the translator block. The e2fsprogs tools will now use
8450 the creator_os field in the superblock to correctly handle different
8451 OS-specific variants of the ext2 filesystem.
8453 E2fsck now fixes inodes which have a the deletion time set, but which
8454 have a non-zero i_link_count field by offering to clear the deletion
8455 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
8456 ext2 kernel behavior) and offered to unlink the file.
8458 If e2fsck sets the clean bit, but nothing else, set the exit code
8459 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
8460 set the filesystem valid bit when it was previously cleared. :-) This
8461 was needed to make the HURD fsck driver happy.
8463 If the user refuses to attach an unattached inode, e2fsck will no
8464 longer set the inode's link count. Otherwise, the inode would end up
8465 getting marked as unused, which might cause loss of data later.
8467 Make the message issued by e2fsck when the superblock is corrupt less
8468 confusing for users. It now mentions that another reason for the
8469 "corrupt superblock" message might be that the partition might not be
8470 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
8472 Make the libext2 library more robust so that e2fsck won't coredump on
8473 an illegal superblock where the blocksize is zero. (f_crashdisk is
8476 By default, create filesystems where the default checkinterval is 6
8477 months (180 days). Linux servers can be robust enough that 20 reboots
8478 can be a long, long time.
8480 Added configure flag --enable-old-bitops, which forces the bitops to
8481 use the old (native) bitmask operations. By default on the sparc
8482 platform, the standard ext2 bit ordering is now used.
8484 Added a new feature to e2fsck to byte-swap filesystems; this can be
8485 used to convert old m68k filesystems to use the standard byte-order
8486 storage for the superblock, inodes, and directory blocks. This
8487 function is invoked by using the '-s' option to e2fsck.
8489 Debugfs's "dump" command has been enhanced so that it writes out the
8490 exact size of the file so that the nulls at the end of the file are
8491 eliminated. The command also accept a new "-p" option which will
8492 attempt to preserve the ownership, permissions, and file
8493 modification/access times.
8495 Debugfs has two new options, -f and -R. The -R option allows the user
8496 to execute a single debugfs command from the command line. The -f
8497 option allows the user to specify a "command file" containing debugfs
8498 commands which will get executed.
8500 Dumpe2fs now pretty prints the check interval, instead of just
8501 printing the check interval as a number of seconds.
8503 Fix bugs in debugfs: the params command when no filesystem is opened
8504 no longer causes a core dump. It is now possible to unlink a file
8505 when a pathname containing a '/' is specified.
8507 Tune2fs has a new -C option which sets the number of times the
8508 filesystem has been mounted.
8510 Fix the chattr '-v' option so that it actually works. Chattr was
8511 being buggy about the -v option parsing.
8516 The directory lib/uuid contains a set of library routines to generate
8517 DCE compatible UUIDs.
8519 Extended ext2fs_namei() to handle symbolic links. Added new function
8520 ext2fs_nami_follow() which will follow last symbolic link in the case
8521 where the pathname points to a sym link.
8523 The ext2fs_block_iterate function will now return the HURD translator
8524 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
8525 iterator to return data blocks only. The ext2fs.h file now defines
8526 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
8527 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
8528 count field of the iterator callback function.
8530 The test script driver now takes an optional second argument, which is
8531 the test case to be run. This allows you to run a test case without
8532 needing to run the entire test suite.
8534 On Linux ELF systems, install the .so files in the correct places
8535 (/usr/lib). The .so files must be stored in the same directory as the
8538 Fixed miscellaneous HURD compilation issues with header file being
8539 included in the right order.
8541 Fixed debugfs so that it resets optind to zero, not one, since setting
8542 optind to zero is more correct.
8545 E2fsprogs 1.04 (May 16, 1996)
8546 =============================
8548 First "official" (1.03 was a limited release only) to support building
8549 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
8552 This package includes a RPM specs file, that it can be built using the
8553 RedHat Package Manager.
8555 E2fsck now prints a hint that if there are lots of incorrectly located
8556 inode bitmaps, block bitmaps, and inode table blocks, the user might
8557 want to try using e2fsck -b 8193 first, to see if that fares any
8560 For ext2 filesystem written with the hurd, debugfs will now print out
8561 the translator field when printing an inode structure.
8563 Lots of miscellaneous linking/installation cleanups:
8565 Libraries are now linked using a relative pathname, instead of
8566 relying on -L working correct. It doesn't, in many cases, including
8567 current versions of GNU ld. This guarantees that the build tree is
8568 linking with the right libraries, instead of the ones installed in
8571 Header files, man pages, and the et/ss shell scripts are now
8572 generated using a custom substitution script, instead of relying on
8573 the configure script. This prevents needless recompilation of
8574 files; in addition, the custom substitution script is much faster.
8576 e2fsck may now be linked dynamically, by using the
8577 --enable-dynamic-e2fsck flag to configure. This is not recommended,
8578 since it increases e2fsck's dependence on other files, but some
8579 people need to save disk space, and other critical programs on their
8580 systems were being linked dynamically anyway.
8582 Programs such as fsck which didn't need to be linked against
8583 libext2fs (or mke2fs which didn't need to be linked against libe2p)
8584 only link against libraries they actually need. Otherwise, those
8585 programs would require the presence of libraries that otherwise
8586 could be removed from a rescue diskette.
8588 The ss include files are now installed correctly so they can
8589 actually be used by another package.
8591 If the profiling libraries are built, they are now installed on a
8592 "make install-libs".
8595 E2fsprogs 1.03 (March 27, 1996)
8596 ===============================
8598 Change the m68k bit numbering for bitmasks to match the bit numbering
8599 used by all other ext2 implementations. (This change was requested by
8600 the m68k kernel development team.)
8602 Support (in-development) filesystem format revision which supports
8603 (among other things) dynamically sized inodes.
8605 Fixed a bug in the ext2 library so that an intelligent error is
8606 returned if mke2fs is run with a ridiculously small number of blocks
8609 Fixed a bug in the ext2 library which required that the device be
8610 openable in read/write mode in order to determine its size. This
8611 caused e2fsck -n to require read/write access when it was not
8612 previously necessary.
8614 Fixed a bug in e2fsck which caused it to occasionally fail the test
8615 suite depending on which version of the floating point library it was
8618 Fixed a bug in e2fsck so that it now halts with a fatal error when
8619 certain superblock consistency checks fail. Previously it continued
8620 running e2fsck, with some potential confusing/damaging consequences.
8622 Added new flag to fsck which allows the root to be checked in parallel
8623 with other filesystems. This is not the safest thing in the world to
8624 do, but some system administrators really wanted it.
8626 Fixed -Wall flames in lib/ss.
8629 E2fsprogs 1.02 (January 16, 1996)
8630 =================================
8632 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
8634 Change e2fsck to print statistics of how many non-contiguous files are
8635 on the system. Note that a file which is larger than 8k blocks, it is
8636 guaranteed to be non-contiguous.
8638 In mke2fs, print a warning message if a user tries to format a whole
8639 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
8640 whole disk, the -F (force) option forces mke2fs to format a whole disk
8643 Fix a bug in fsck where in some cases it might start checking
8644 partitions in the next pass before it finishes checking partitions in
8645 the current pass. This still won't cause two partitions on the same
8646 disk will be checked, so it's rarely a problem in real life.
8648 Patch lsattr so that it won't hang when checking a named pipe.
8650 Minor compilation fixes:
8651 * Fix the order of libraries that were linked in debugfs.
8652 * Allow the sources to be compiled with -ansi turned on.
