1 E2fsprogs 1.43.2 (September 1, 2016)
2 ====================================
4 Fix resize2fs so it will not crash if there is an extended attribute
5 block but it doesn't need to migate any blocks during an off-line
8 Fix a crash when mke2fs or debugfs tries to copy in a directory
9 hierarchy containing an empty directory
11 Mke2fs will now use a larger journal by default for filesystems
12 greater than 128 GB. (1GB instead of 128 MB.)
14 Fix an alignment bug in e2fsck which caused sparc64 architectures to
15 crash when replaying the journal on file systems with a 64-bit block
18 Clarify the message printed by tune2fs message when the user needs to
19 run e2fsck so it's clear that the -f flag to e2fsck is needed to
20 force a full e2fsck scan. (Addresses Debian Bug: #828022)
22 Fix a bug in e2fsck caused by a power failure during e2fsck's journal
23 replay could leave the file system in a state where if the file system
24 is mounted without doing a full e2fsck scan, the file system could get
27 Fix the logic in e2fsck which decides when to repair legacy negative
30 Add a command to debugfs to copy the inode structure from one inode to
33 Fix a typo in debugfs's stat command when printing out the dtime field
34 on file systems with an extended timestamp.
36 Fix big endian bugs in the e2undo program. (Addresses Red Hat Bug
39 Debugfs's logdump can now properly handle journals larger than 2GB.
41 Avoid installing the man page for fuse2fs if it has not been built.
43 Update the Catalan, Chinese, Danish, Dutch, French, German, Polish,
44 Swedish, Ukrainian translations and added new translations for
51 Fix portability problems in fuse2fs. Previously it wouldn't build on
52 systems with older glibc versions where clock_gettime() is only
53 available in the librt library, and if libintl is not bundled into the
56 Remove complicated logic which caused a static code analyzer to flag a
57 false positive. (A static code analyzer also found a valid bug in
58 deciding when to repair a legacy negative timestamp encoding, so
59 eliminating false positives is important.)
61 Fixed a bug where the ext2fs library cloud provoke when a
62 extfs2_zero_blocks() is used (via fallocation, initializing a file
63 system, uninitialized uninitialized inode table blocks) after a
64 different file system which also used ext2fs_zero_blocks().
66 Enable the unix_io manager in the ext2fs library so it can accept the
67 use of a file descriptor. This is helpful in cases where the file
68 descriptor comes from temporary file created using O_TMPFILE, or
69 passed in from a unix domain socket.
71 Fix a Windows64 portability bug.
74 E2fsprogs 1.43.1 (June 8, 2016)
75 ===============================
77 Fixed e2fsck so that it would correctly update the project quota usage
78 when deleting a corrupted and inode, and fixed mke2fs so it wouldn't
79 dereference memory beyond the small inode structure (which was wrong,
80 but worked mostly by accident unless hardening or some security malloc
83 Fixed a large number of FreeBSD portability problems. (To build on
84 FreeBSD, however, we still need to use GNU Make and redirect dd to use
87 The configure script now supports --enable-hardening, which enables
88 stack protection, fortify, read-only relocation tables, immediate
89 dynamic symbol binding, and text segment ASLR (if the kernel has
90 userspace ASLR support enabled) by enabling position independent
91 executable code. (Distributions who want to do their own special
92 thing can set CFLAGS, CFLAGS_SHLIB, CLFAGS_STLIB, LDFLAGS,
93 LDFLAGS_SHLIB and LDFLAGS_STATIC as appropriate.)
95 The configure script now supports --disable-tdb since on 64-bit
96 systems, it's much faster to just enable additional swap space. The
97 scratch_files feature in e2fsck.conf is mostly only useful on 32-bit
100 Fixed the Direct I/O fallback codepath in the Unix I/O manager so that
101 read/modify/write worked correctly. Fortunately in practice (with the
102 exception of the Undo handler when running on FreeBSD) used this buggy
103 codepath. so file systems weren't getting corrupted.
105 Mke2fs will now warn if the user provides a label which is too long.
106 (Addresses Debian Bug: #791630)
108 Debugfs's rdump command now works correctly when dumping the root
109 directory of a file system. (Addresses Debian Bug: #766125)
111 Fixed a bug in debugfs so it would correctly calculate a block group's
112 checksum field field on 64-bit ssystems.
114 E2fsck now has a much more understandable error message when the
115 journal superblock is corrupt and the user declines to fix it.
116 (Addresses Debian Bug: #768162)
118 Fixed support of extended timestamps on 64-bit systems.
120 Updated/fixed various man pages. (Addresses Debian Bugs: #766379,
121 #761144, #770750, #428361, #766127)
123 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #825868)
129 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
131 Fixed Android build makefiles (which was missing a newly added file in
134 In general, checks on s_creator_os have been removed in favor of
135 feature flag specific checks; if there is something that can't be
136 checked via the presence of a feature flag, we will simply check
137 whether the creator OS is *not* EXT2_OS_HURD which is the one
138 operating system where there has been extensive abuse of the
141 The libmagic libary has been suppressed when running the regression
142 test suite to avoid false test failures caused by differences between
143 versions of libmagic (and/or the magic number database).
145 The tests/test_script progam now accepts the --failed option, which
146 will run those tests that had previously failed.
148 Fixed tests build on those systems which require LDFLAGS to be set.
150 Fixed the regression test suite so it will properly filter out version
151 numbers with two components (such as 1.43) from log files before
152 comparing them with the expected golden output.
155 E2fsprogs 1.43 (May 17, 2016)
156 =============================
158 Add support for the ext4 metadata checksum, checksum seed, inline
159 data, encryption, project quota, and read-only features.
161 Support for the very old, experimental, and never-added-to-mainline
162 compression feature has been removed.
164 Mke2fs will now create file systems with the metadata_csum and 64bit
165 features enabled by default.
167 The mke2fs program will now support multiple -O options (instead of
168 just ignoring all but the last -O option).
170 Mke2fs will now correctly determine the size of a file system and
171 handle the discard operation correctly when the "-E offset=NNN" is
172 used. (Addresses Debian Bug: #803629)
174 The tune2fs program will ask the user for confirmation before starting
175 dangerous operations if the terminal is available, and it will replay
176 the journal if necessary.
178 Add an ext2/3/4 FUSE server
180 Debugfs can now modify extended attributes and journal transactions.
182 Debugfs now can properly display and set extended timestamps.
184 E2fsck will offer to fix extended timestamps that were incorrectly
185 encoded by older kernels.
187 Fix miscellaneous MMP bugs in debugfs.
189 Fix sparse_super2 bugs in mke2fs and resize2fs.
191 Fix or improve offset support in mke2fs, e2undo, and libext2fs.
193 The resize2fs command can now convert file systems between 64-bit and
196 Fix potential out-of-bounds memory access in resize2fs when doing a
197 large off-line file system grow operation.
199 We now use a new e2undo file format which is much more efficient and
200 faster than the old tdb-based scheme. Since it so much faster,
201 e2fsck, tune2fs, debugfs, and resize2fs now also can support using
202 creating an undo file.
204 The mke2fs command can now set the error behavior when initializing
205 the file system (so the administrator doesn't have to issue a separate
208 Teach mke2fs to parse a human-readable argument for -i option.
210 Teach mke2fs to automatically handle creating file systems > 500T by
211 automatically enable the meta_bg feature.
213 Mke2fs will now prompt for user verification before rewriting a file
214 system's superblock using the -S option.
216 Mke2fs no longer complains if the user tries to create a file system
217 using the entire block device (e.g., without using a partition). The
218 minor number convention is not used by all block devices, and it's
219 quite normal in some circumstances to create a file system on /dev/sdc
220 instead of /dev/sdc1.
222 Fix an "mke2fs -d" bug which could create inodes with invalid
223 extended attribute blocks
225 E2fsck is now much more paranoid about not freeing or corrupting
226 critical metadata blocks, such as inode table blocks, even if
227 corrupted indirect blocks or extent trees point at these blocks.
229 E2fsck now prints block ranges in pass1b instead of listing all of the
232 E2fsck will try to expand the root directory if the lost+found can't
233 be linked to the root directory. Also, offer to use the root
234 directory if lost+found can't be created.
236 E2fsck is now more paranoid handling corrupted extent trees as well as
239 E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
240 to recover from a corrupted extent tree, or (c) to convert
241 block-mapped inodes to use extents.
243 E2fsck now has a readahead mechanism which can significantly speed its
244 performance, especially on RAID arrays.
246 E2fsck now has a "yes to all" option which the user can give if she is
247 tired of answering 'y' to a very large number of questions.
249 E2fsck will now ignore the badblocks inode if the contents of the
250 badblocks inode indicate that the portion inode table containing the
251 badblocks inode is bad. (We must go deeper...)
253 E2fsck can now correctly fix directory with holes on bigalloc file
256 E2fsck will now check for extent mapped inodes with no extent header
257 and clear them if found.
259 E2fsck now checks to make sure the extended attribute header doesn't
260 result in the xattr extending beyond the bounds of the inode
262 Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
263 revoke records if the journal is corrupted.
265 Fixed a bug in e2fsck which could cause it loop forever if a special
266 inode has too many invalid block mappings.
268 Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
269 confused if an attempt to allocate a block can't find any free space
272 E2fsck will no longer try to force rewrite blocks located beyond the
275 The e2fsck program will no longer update the quota inodes when it is
278 Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
279 extent-mapped directory.
281 Fixed a bug in resize2fs which could lead to resize2fs crashing or a
282 corrupted file system if the file system is almost completely full
283 when trying grow a file system and we need to allocate blocks to grow
284 the block group descriptors.
286 Fixed a bug in resize2fs which could cause it to get fooled trying to
287 determinthe the RAID array's stride when flex_bg is enabled.
289 Fix resize2fs bug that could leave block allocation bitmaps
292 The dumpe2fs output has been improved so it is cleaner and always fits
293 within 80 columns. Also added a more easily machine-parsable output
296 The mke2fs program can now pre-populate a file system from a directory
297 hierarchy using the -d option.
299 The mke2fs program now skips zeroing inode table blocks if they were
300 already zeroed using the discard feature.
302 Check to make sure file system features which can not be supported by
303 HURD are not enabled if the file system is created to be
306 Added a new e2fuzz command that will fuzz an ext4 image for testing
309 The debugfs logdump command can now deal with 64-bit revoke tables
310 correctly. Also, "logdump -O" will print the old log contents (before
311 the journal was replayed).
313 The debugfs bmap command can now be used to set or allocate a physical
316 Fixed a bug so "filefrag -B -e -v" does not return a separate entry
319 The filefrag program now accounts for holes in sparse files created by
320 the file punch operation as an expected/optimal mapping.
322 The file I/O functions now correctly handle inodes containing
323 uninitialized blocks.
325 Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
326 file system won't result in corrupted block bitmaps.
328 Updated/fixed various man pages. (Addresses Debian Bug: #798425)
334 Fixed coverity, sparse gcc -Wall, and clang warnings/nits.
336 Added Android build files so that e2fsprogs can be built in the
339 Reduce the use of libc functions in libext2fs that may not be present
340 in the boot loader environment, at least for those functions that are
341 needed by boot loadsers such as yaboot.
343 Developers can now overide the debugging and optimization flags by
344 redefining the CFLAGS makefile macro.
346 The libext2fs library now has support for fallocate.
348 The mke2fs command will now ask the user for confirmation if block
349 device or image file contains an existing file system image, and
350 stdout and stdin are connected to a tty.
352 The libext2fs library now picks a more intelligent goal block when
353 doing block allocations.
355 The libext2fs library will now automatically set the BLOCK_UNINT flag
356 if all of the blocks in a block group are free, to speed up future
357 e2fsck and dumpe2fs operations on the file system.
359 Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
362 The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
365 The ext2fs_bmap() function supports new flags BMAP_UNINIT and
368 The ext2fs_new_block2() function will now call the alloc_block hook
369 before checking fs->block_map.
371 Support for the MMP feature can now be disabled at compile time.
373 Added support to manipulate extended attributes to libext2fs.
375 Added a lot of new regression tests.
377 Added endian annotations so it's possible to scan e2fsprogs for endian
378 problems using a static code analyzer.
380 Fixed memory leaks in libext2fs.
382 The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
383 There is now a script in the contrib directory which automates most of
386 The build system will now run cppcheck (a static code analysis tool)
390 E2fsprogs 1.42.13 (May 17, 2015)
391 ================================
393 Fixed a potential buffer overflow while closing a file system in
394 libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
396 Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
397 (Addresses Debian Bug: #760275)
399 Fixed a deadlock which occurs when using systemd and e2fsck.conf's
400 logging feature. (Addresses Debian Bug: #775234)
402 Fixed a bug which could cause programs using libext2's inode table
403 scanning functions from crashing on certain corrupted file systems.
404 (Addresses Debian Bug: #773795)
406 Fixed dumpe2fs so it won't crash if the user doesn't specify a block
407 device (file system). (Addresses Debian Bug: #764293)
409 Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
410 will report the correct directory inode containing the inconsistency.
412 If e2fsck fails to grow the dir_info structure due realloc(3) not
413 having enough memory, it will now fail with explanatory message
414 instead of staggering on failing with a confusing internal error
417 The tune2fs program will zero out the superblock journal backup
418 information when removing a journal from a file system.
420 The mke2fs program now enables the large_file feature by default.
422 Fixed a bug which could cause badblocks to crash if there are millions
423 and millions of bad blocks.
425 Fixed some use-after-free bug in resize2fs and e2fsck.
427 Fixed a memory leak in tune2fs.
429 Fixed some bigendian bugs that had crept into both indirect and extent
430 handling inside libext2fs.
432 Updated/fixed various man pages.
434 Update Esperanto, German, and Spanish translations. Added Danish
440 Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
442 Clean up some build system problems (build failures with various
443 configure options, fix Posix portability issues, etc.)
445 The functions ext2fs_inode_alloc_stats[2]() and
446 ext2fs_block_alloc_stats[2]() now check the inode and block numbers
447 passed to them, to avoid crashes caused by buggy callers.
449 The libext2fs directory iterator will now check for an invalid
450 directory entry length instead of possibly walking off the end of the
454 E2fsprogs 1.42.12 (August 25, 2014)
455 ===================================
457 Fix various e2fsck bugs when trying to repair bigalloc file systems.
459 E2fsck can now repair a file system with an overly large
460 s_first_meta_bg field, which had previously caused all e2fsprogs
461 programs to crash when trying to open such a file system.
463 Fix e2fsck so that it can correctly fix a number of rare file system
464 corruptions that were discovered when using a file system fuzzer.
466 Fix e2fsck so it does not try to write back block group descriptors if
467 they have not been modified.
469 Mke2fs program will now place metadata blocks in the last flex_bg so
470 they are contiguous. This reduces free space fragmentation in a
471 freshly created file system, as well as allowing mke2fs commands which
472 request extremely large flex_bg size to succeed.
474 Mke2fs now creates hugefiles more efficiently (with fewer extent tree
477 Fix a 32/64-bit overflow bug that could cause resize2fs to loop
478 forever. (Addresses-Launchpad-Bug: #1321958)
480 The resize2fs program will now use much less memory when resizing very
483 Fix a bug which could cause resize2fs to get confused and produce a
484 corrupted file system when shrinking a file system that had been
485 previously expanded and converted to use the meta_bg file system
486 format, but which no longer needs to use the meta_bg file system
487 format any longer. This typically happened with large (> 16TB) file
488 systems. (Addresses Debian Bug: #756922)
490 The e4defrag program will now defrag backwards-allocated files.
492 Fix tune2fs updating UUID's when manipulating file systems with
493 external journals (both the file system and journal UUID).
495 Fix tune2fs so it can remove an external journal for file systems with
498 Add a new debugfs command, "inode_dump", which prints the inode in hex
501 The debugfs's "set_inode_field" will now automatically allocate blocks
502 for indirect blocks and extent tree blocks.
504 Fix debugfs's "set_inode_field" so can properly handle
505 "block[IND|DIND|TIND]".
507 The debugfs "rdump" command will now take multiple source arguments.
509 Fixed a double close(2) bug in "rdump" and "rdump -p".
511 Fix debugfs's argument parsing for the freefrag command.
513 Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
514 (Addresses Launchpad Bug: #1356496)
516 Clarified messages that were confusing users in debugfs, e2fsck,
517 mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
520 Dumpe2fs will now complain if extra arguments are given to it.
521 (Addresses Debian Bug: #758074)
523 Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
525 Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian, and
526 Vietnamese translations.
531 The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
532 number of system calls issued.
534 Fixed profiled build.
536 The libext2fs library will now more efficiently split an extent tree
537 index block when appending to an end of a file.
539 Fixed free block accounting for 64-bit file systems.
541 Add a new function ext2s_inode_size_set() which takes care of all of
542 the required feature flag modifications.
544 The regression tests no longer require the presence of the md5sum
547 Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
550 Fix various Coverity warnings (#1225003, #1229243, #1252003)
553 E2fsprogs 1.42.11 (July 9, 2014)
554 ================================
556 Add support so that mke2fs can create hugefiles so that they are
557 aligned relative to the beginning of the disk, instead of relative to
558 the beginning of the partition, using the mke2fs.conf configuration
559 parameter "hugefiles_align_disk".
561 Fix a bug which causes e2fsck to abort a journal replay on a file
562 system with bigalloc enabled. (Addresses Debian Bug: #744953)
564 Add sanity checks so that mke2fs will refuse insanely large flex_bg
565 counts specified by the -G option. Insanely large flex_bg sizes can
566 result in a file system which can't be unmounted, or with extremely
567 pessimal metadata layouts.
569 The mke2fs program will provide a better metadata layout for
570 moderately large (but believable) flex_bg counts, such as 133,072.
572 The mke2fs progam will also check the kernel version number to
573 determine whether the lazy_itable_init option is supported, so that
574 lazy inode table initialization can be used even if the ext4 is
575 compiled as a module which isn't loaded at the time that mke2fs is
578 Add description of ext4's mount options to the ext4 section 5 man
581 Improve the chattr man page and clean up the chattr usage message.
583 E2fsck will now automatically fix a last mount time or last write time
584 which is in the future in preen mode, instead of aborting the fsck
587 Mke2fs will now check the file system revision number requested by the
588 command line, and reject it if it is too large. A file system with an
589 unsupported revision number will not be accepted by any of the other
590 file system tools, and this command line option is rarely used, so
591 let's try to help the user not shoot their own foot off.
593 The debugfs progam can now set the error count and associated
594 first_error and last_error fields in the superblock using the
595 set_super_value command.
597 Resize2fs will not try to calculate the minimum size of a file system
598 if it contains errors. Otherwise a very badly corrupted file system
599 image can cause the minimum size calculation to loop forwever. Since
600 resize2fs will not allow a file system marked as containing errors to
601 be resized. It's pointless to calculate the minimum size, so just
604 Fixed a typo in one of mke2fs's error message.
606 If filefrag runs into an error, it will continue processing the rest
607 of the files specified on thec ommand line, but then exit with an
610 Filefrag now prints some additional new flags (such as
611 FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
613 Fixed support in filefrag for files with > 2**32 blocks on 32-bit
616 Fixed a file descriptor leak in debugfs when copying files.
618 Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
619 to create file systems larger than 2GB on 32-bit platforms.
620 (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
622 Add Esparanto and Ukrainian translations, and update Czech, Dutch,
623 French, German, Italian, Polish, Sweedish, and Vietnamese
626 Fixed various compiler warnings.
632 The gcc "-checker" option has been long deprecated, so remove support
633 from e2fsprogs. It was causing a few people to be confused when they
634 tried enabling the configure option.
636 Update to the latest version of the config.status and config.rpath
637 files, as well as newer versions of the autoconf files in aclocal.m4.
638 Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
639 people who want to use autoreconf to do so.
641 Make the use of strptime() function in debugfs to be more portable to
642 fix regression test failures for FreeBSD and MacOS.
644 A few miscellaneous changes designed to make life easier for
647 Fix the f_quota test and some Makefile dependencies if quota support
650 Fix cross-compilation support, which got broken in 1.42.10.
651 (Addresses Debian Bug: #753375)
653 Delete lib/ext2_types.h on a make clean, and build it as necessary.
655 Add a debug program used for libext2fs unit tests.
657 Clean up the tests so that it avoids using GNU-specific behaviour in
658 mktemp. Make sure the temporary files are cleaned up if the tests are
661 Add a new ext2fs_close_free() helper function which automatically
662 takes care of freeing the ext2_filsys structure even if ext2fs_close()
666 E2fsprogs 1.42.10 (May 18, 2014)
667 ================================
669 Mke2fs now creates file systems in regular files (which is very often
670 used when maintaining virtual machine images) without requiring the
671 user to use the force option. In addition, the mke2fs output has been
672 made much less verbose and only displays information that users will
673 be more likely to find useful by default.
675 Mke2fs now will ask the user to confirm that they want to continue
676 before wiping out a pre-existing file system, partition table, or LVM
679 Mke2fs now has the ability to create file systems where all the
680 metadata is located at the very beginning of the device. This can be
681 useful for flash devices which have SLC flash at the beginning of the
682 disk, for FAT compatibility, for example. As part of this, mke2fs and
683 tune2fs can control the location of the data blocks used by the
684 journal inode. In addition, the new sparse_super2 feature allows for
685 even fewer (anywhere from zero to two) backup superblocks.
687 Mke2fs now uses much less CPU when allocating the blocks used for very
690 Mke2fs can now support creating a file system at an offset. This can
691 be useful when creating a disk image for virtual machines (Addresses
694 Previously, e2fsck had a number of very serious bugs when checking a
695 file system wich used the new the quota file system option (where the
696 quota inodes were stored in hidden inodes) and the quota inode was
697 inconsistent with the actual usage data. This problem was documented
698 in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
699 been fixed in 1.42.10, so the quota should be safe to use with
702 Fixed in a bug in resize2fs which could cause shrink operation fail in
703 the unlikely situation when the inode table needs to be moved to a
704 location before the current location.
706 Resize2fs now has a much more accurate (and less conservative)
707 estimation of how far the file system can be shrunk. This allows a
708 mostly empty filesystem which is a few terabytes, to be shrunk to a
709 few megabytes in a single resize2fs -M operation.
711 E2fsck will now force a full file system check if there are any file
712 system inconsistencies detected in the super block.
714 The filefrag program will now display hte shared extent flag, which is
715 used by file systems such as btrfs.
717 If the number of inodes in the file systems is larger than the time
718 that file sytem was created (as measured by the number of seconds
719 since January 1, 1970) e2fsck would print a scary (but otherwise
720 harmless) warning of file system corruption for each inode in the
721 orphan list. This false positive has been fixed.
723 The e4defrag program has been fixed so it will no longer refuse with
724 filesystem with the 64-bit or the bigalloc feature enabled.
726 The logsave progam will print a much less scary message which could
727 lead users to believe something has gone very wrong with e2fsck exits
728 with a non-zero exit status (since this is normal after e2fsck has
729 automatically fixed a file system corruption during a preen
730 operation). (Addresses Debian Bug: #468821)
732 When creating a file system which is larger than 16TB, the
733 resize_inode option must be disabled -- since the resize_inode simply
734 doesn't support reserving metadata block numbers which is larger than
735 32 bits. The mke2fs program does this automatically if the file
736 system size is determined automatically. It will now also do this if
737 the file size is specified explicitly.
739 Fixed bugs associated with resize2fs and shrinking bigalloc file
742 The e2fsck program will no longer try to add a UUID on a mounted file
743 system with checksums enabled, since this could leave the file system
746 Tune2fs will allow the removal of an external journal from file system
747 which is marked as needing the journal replayed when the force ("-f")
748 option is given twice. (Addresses Debian Bug: #559301)
750 Tune2fs will no longer support enabling sparse_super if the meta_bg
751 file system feature is enabled, since it could result in data loss.
752 In practice, all modern file systems have sparse_super is enabled, so
753 it's not worth trying to change how tune2fs handles enabling the
754 sparse_super feature.
756 Fixed support for 1k block file systems with the meta_bg feature.
758 When the superblock is corrupt, e2fsck can't figure out the location
759 of the alternate superblock. Unfortunately, the routine that
760 calculates the location of the alternate superblock uses 8193 if it
761 can't figure this out, so the message printed by e2fsck always
762 suggests using "e2fsck -b 8193". This message has been fixed to
763 suggest both the superblock location of 8193 and and 32768.
764 (Addresses Debian Bug: #719185)
766 The lookback mount detection code that was introduced in 1.42.9 wasn't
767 actually compiled in due to an autoconf oops, so it's fixed now in
768 1.42.10. (Addresses Debian Bug: #497984)
770 A bug introduced in 1.42.9 would cause debugfs to print two error
771 messages if it found an error while parsing a user-supplied block
772 number. This has been fixed in 1.42.10.
774 Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
775 Vietnamese translations. (Addresses Debian Bug: #703048)
777 Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
780 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
786 Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
788 Allow the location of pkg-config files to be specified independent of
789 the libdir location via a makefile variable.
791 Fixed parse-types.sh not to complain when cross-compiling and the
792 sizes of types are different between the target architecture and the
793 architecture of the build system
795 Allow the regression test suite to work correctly on systems which do
796 not have the "truncate" or "mksawp" programs.
798 Allow e2fsck to build correctly on systems (such as Android) that do
799 not have the signal.h file.
801 E2fsprogs now has code coverage testing which can be enbled using
802 "configure --enable-gcov".
804 The libe2p.h header file can now be used included by C++ programs.
806 The profile/config file used by e2fsck and mke2fs will interpret
807 numbers with a leading 0 character to mean that they should be
808 interpreted as an octal integer.
810 The extent handling functions in libext2fs have been improved so they
811 have proper rollback when there is an error splitting an extent. Also
812 fix a number of bugs when punching holes in files, and fix an
813 off-by-one bug when inserting an extent into an empty inode.
815 The libext2fs library now handles the support of BLOCK_UNINIT by
816 clearing the portion of block bitmap when it is loaded, instead of
817 when it is used. This reduces the chances of bugs, and and simplifies
818 the code. It also means that debugfs will properly show that blocks
819 in uninitialized block groups as being unused when using the testb
822 The e4defrag program will try to use fadvise64 or posix_fadvise64() if
823 it is present, which allows 64-bit offsets on 32-bit systems.
826 E2fsprogs 1.42.9 (December 28, 2013)
827 ====================================
829 Mke2fs will detect an attempt to create a file system on a loop
830 mounted file and complain without the -FF option. Also fixed mke2fs
831 so it allows the creation of a file system on a mounted device with
832 two -F options, as documented in the man page, instead of three -F
835 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
836 libext2fs to correctly handle bigalloc and 64-bit file systems. There
837 were many corner cases that had not been noticed in previous uses of
838 these file systems, since they are not as common. Some of the bugs
839 could cause file system corruption or data loss, so users of 64-bit or
840 bigalloc file systems are strongly urged to upgrade to e2fsprogs
843 The tune2fs program will now not allow changing the uuid on a mounted
844 file system which has the uninit_bg feature enabled. This avoids a
845 nasty race where the kernel and tune2fs are both retrying rewrite the
846 group descriptors at the same time, with different ideas about what
849 When e2fsck is rehashing an extent-mapped directory, it's possible
850 (although very rare) that an extent block will need to be allocated;
851 fix e2fsck to make sure that the block gets marked as used.
853 Mke2fs will now properly set the LARGE_FILE feature when creating a
854 journal >= 2GB --- which can happen when using 64k block size.
856 Fixed debugfs so that its freei command will correctly handle a request
857 to free a range of consecutive inodes.
859 Fixed 2fsck so it will not erroneously complain that an external journal
860 is invalid if it is exactly 2**32 blocks.
862 Fixed e2fsck so it won't try checking for, and adding, a missing
863 lost+found directory when running in read-only mode.
865 Fixed e2image so that progress information won't get leaked to stdout.
866 (Addresses Red Hat Bugzilla: #1327329)
868 Fixed e2image to avoid some buffer overruns which would cause it to when
869 creating a "standard (non-raw, non-qcow2) image file. Standard
870 e2image files are actually very rarely used, so we didn't notice when
871 the changes to enable the qcow2 format broke this e2image mode.
873 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
874 on the resize_inode feature when the meta_bg feature is set, since
875 these two features can not be set at the same time.
877 Fixed tune2fs so that when it disables the quota feature, it updates all
878 of the backup superblocks.
880 Fixed dumpe2fs that would cause it to abort when run using an image file
881 when trying to print the journal information (which is not present in
882 an e2image created image file).
884 Fixed a potential integer overflow in e2reefrag.
885 (Addresses-Debian-Bug: #718205)
887 Enhance debugfs so that when copying a sparse file from a native file
888 system into the file system image using the "write" command, it will
889 create a sparse file into the destination file system.
891 Enhanced debugfs so it can support a command line which is up to 8k
894 E2image will refuse (unless the -f option is specified to force the
895 issue) to create a raw or qcow image using a mounted file system,
896 unless the -f option is specified to force the issue.
898 E2image has been optimized for using it to efficiently copy a file
899 system by only copying the allocated blocks, by using the options -ra.
900 New options (-o and -O) have been added so that a source and
901 destination offset can be given. The -p option will print progress
902 information so the user will know how far along the copy is going.
903 And finally, the new option -c is useful for updating a file system on
904 an SSD, by avoiding unnecessary writes. E2image can also shift a file
905 system image by doing an in place move.
907 Fix a regression introduced in 1.42.8 which would cause e2fsck to
908 erroneously report uninitialized extents past the EOF (as determined by
909 i_size) to be invalid.
911 Fixed resize2fs so under a corner case when an inode has a complex
912 extent tree, it will not corrupt an interior node in the extent tree.
914 Fixed resize2fs which would sometimes corrupt a file system when
915 shrinking a file system to a minimum size using resize2fs -M.
916 (Addresses Debian Bug: #660793)
918 Fixed resize2fs so that it will relocate inode table blocks if this
919 becomes necessary when shrinking the file system.
921 Fixed resize2fs and e2fsck so they will not crash when hit a failure
922 while operating on a file system with the MMP feature enabled.
924 Fixed a bug in debugfs which caused it create an invalid inode when
925 trying to write a zero-length file.
927 E2fsck will no longer crash if it tries to delete an invalid
928 extent-mapped symlink.
930 E2fsck will no longer crash if it comes across an directory which is
931 larger than 2GB (which is not allowed in valid file systems).
933 Fixed debugfs's help texts to fully document all options and otherwise
936 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
939 Fixed various Debian Packaging Issues (#698879, #721365)
945 Fix sparse, gcc -Wall and clang nits.
947 Update config.{guess,sub} to the latest version
949 Fixed various memory and file descriptor leaks on various error paths,
950 as well as some missing error return checks, which were found using
953 Run sparse against source files when building e2fsprogs with 'make
954 C=1'. If instead C=2, it configures basic ext2 types for bitwise
955 checking with sparse, which can help find the (many many) spots where
956 conversion errors are (possibly) happening.
958 Allow the regression test to be run in chrooted environments where
959 /etc/mtab might be missing.
961 The ext2fs_punch() function, which was introduced in 1.42, was broken
962 in many ways, but this was never noticed since it wasn't used for
963 anything significant. Some of the bugs include failing when trying to
964 punch a completely sparse file, failing when punching an extent-mapped
965 inode when the starting block was at the beginning of the inode, and
966 not being able to punch a single block (where start_blk == end_block).
967 It also didn't handle being passed an invalid, too-large ending block
968 number, and didn't handle properly terminate at the right place when
969 operating on an indirect-mapped inode.
971 Fixed some minor typo's in the error catalog for libext2fs.
973 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
974 setting the file size, to zero the rest of the block to the end of the
975 file, so that if an ext4 FUSE driver tries to extended the file, that
976 we don't avoid stale data from being returned.
978 Fixed ext2fs_bmap() to disallow clients from trying to map or set
979 logical blocks which are larger than what an extent-mapped or indirect
980 block-mapped inode can allow.
982 If debugfs (or some userspace program using libext2fs) creates a file
983 which is larger than 2GB, make sure the large_file feature flag gets
986 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
987 directory which are large enough, the directory entry could get
988 inserted more than once in the directory.
990 If quota support is disabled (which is the default), make sure that
991 all traces of the quota support is removed from usage messages, man
992 pages, and tune2fs must not be able to enable the quota file system
993 feature. (Addresses Red Hat Bugzilla: #1010709)
995 The ext2fs_file_write() now updates i_size on a successful write,
996 instead of only updating i_size wen the file is closed via
999 Added a shell script, populate-extfs.sh which uses debugfs to populate
1000 an ext2/3/4 file system image from a given directory. It is similar
1001 to the genext2fs program, but it supports ext3 and ext4 file system.
1003 Add changes to the libext2fs library to support block group
1004 descriptors larger than 64 bytes (for future compatibility).
1006 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
1007 leave an extra block in the file when truncating the file down to
1010 The html version info pages are now built using makeinfo --html
1011 instead of the unmaintained and now-obsolete texi2html program.
1014 E2fsprogs 1.42.8 (June 20, 2013)
1015 ================================
1017 As a part of mke2fs's option parsing cleanup, the use of the -R option
1018 will give a warning that it is depreated (it has been so documented
1019 since 2005) and -E should be used instead.
1021 Mke2fs will not give warnings about the bigalloc and quota options in
1024 If an invalid journal size is given to mke2fs, it will now complain
1027 Debugfs was erroneously giving spurious error messages for certain
1028 extent_inode subcommands which take arguments (split_node,
1029 replace_node, and insert_node). This has been fixed.
1031 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
1032 other programs is used by mke2fs.
1034 Change mke2fs so that it does not set the root directory to the real
1035 uid/gid of the mke2fs process. Add the extended option root_owner to
1036 override this behavior.
1038 Fix resize2fs when shrinking file systems to make sure that bitmap
1039 blocks aren't left outside the bounds of the shrunken file system.
1040 This could happen with flex_bg file systems that were grown using
1041 the old online resizing algorithm.
1043 E2fsck will now detect and repair corrupted extent trees which contain
1044 invalid extents at the end of the extent tree leaf block.
1046 E2fsck will now longer complain about zero length extended attribute
1049 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
1052 Add safety check so tune2fs will not attempt to set the inode size to
1053 be larger than the block size.
1055 Fix e2fsck so it can check a read-only root file system with an
1056 external journal. (Addresses Debian Bug: #707030

1081 Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
1082 SEEK_CUR is used with large files.
1084 The ext2fs_read_inode_full() function will no longer use
1085 fs->read_inode() if the caller has requested more than the base 128
1086 byte inode structure and the inode size is greater than 128 bytes.

1096 E2fsprogs 1.42.7 (January 21, 2013)
1097 ===================================
1099 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
1100 quota features are still under development. For more information
1102 * https://ext4.wiki.kernel.org/index.php/Bigalloc
1103 * https://ext4.wiki.kernel.org/index.php/Quota
1105 Add some new options to filefrag from Lustre's patches to e2fsprogs:
1106 * add -k option to print extents in kB-sized units (like df -k)
1107 * add -b {blocksize} to print extents in blocksize units
1108 * add -e option to print extent format, even when FIBMAP is used
1109 * add -X option to print extents in hexadecimal format
1111 Fix resize2fs so that it can handle off-line resizes of file systems
1112 with the flex_bg feature but without a resize_inode (or if we run out
1113 of reserved gdt blocks). This also fixes a problem where if the user
1114 creates a filesystem with a restricted number of reserved gdt blocks,
1115 an off-line resize which grows the file system could potentially
1116 result in file system corruption.
1118 Fix a resize2fs bug which could cause it to corrupt bigalloc file
1119 systems when doing an off-line resize.
1121 Further optimize resize2fs so it doesn't use quite as much CPU when
1122 resizing very large file systems.
1124 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
1125 possibly corrupt the file system while resizing 64-bit file systems.
1127 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
1128 mke2fs crash due to a divide-by-zero if the 64bit file system feature
1131 Add better error checking to mke2fs to check for invalid parameters
1132 when creating bigalloc file system.
1134 When creating bigalloc filesystems, the -g option to mke2fs will now
1135 specify the number of clusters per block group.
1137 Add to debugfs the functionality to corrupt a specific file system
1138 block via the "zap_block" command.
1140 Add to debugfs the functionality to print out a hex dump of a block in
1141 the file system via the "block_dump" command.
1143 Add to debugfs the functionality to manipulate the extent tree
1144 directly via the "extent_open" command.
1146 Fixed debugfs's mknod command so that it updates the block group
1149 Fix e2fsck so it can detect and fix inconsistencies in the interior
1150 nodes of an inode's extent tree.
1152 Fix a potential memory corruption failure in e2fsck's error path if
1153 the call to ext2fs_open2() fails.
1155 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
1156 resulting file name for the log file is longer than 100 bytes, that it
1157 properly handles this situation instead of crashing.
1159 E2fsck will now report the amount of memory that it attempted to
1160 allocate when a memory allocation request fails, to make it easier to
1161 track down the problem.
1163 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
1164 Lustre Bug: LU-1888)
1166 E2image can now include all data blocks in the e2image output file
1167 when the user specifies the -a option.
1169 If e2fsprogs is compiled without --enable-quota, make sure that
1170 tune2fs can not turn on the feature for new-style quota support, since
1171 afterwards, none of the e2fsprogs tools will be willing to touch that
1174 Optimize e2fsck's so that it uses much less CPU for large file
1175 systems. This can result in significant speedups, especially on
1176 CPU-constrained systems. This was primarily done by optimizing
1177 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
1179 Fix debugfs's htree command so that all its messages are sent through
1182 Fixed debugfs's "dump_file" and "cat" functions work correctly
1183 on file systems whose block size is greater than 8k.
1185 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
1186 less memory. (Addresses Google Bug: 7269948)
1188 Update the spd_readdir.c file in the contrib directory to include some
1189 additions which were made in 2008 that didn't get folded into the
1190 version which we checked into the e2fsprogs source tree. These
1191 enhancements include thread safety, support for readdir64_r(), and
1192 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
1194 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
1197 Add a command to debugfs to create symlinks.
1199 Document the bigalloc feature in the mke2fs man page. (Addresses
1200 Debian Bug: #669730)
1208 Fix a spelling typo in the libext2fs texinfo documentation.
1210 Change the output from "make check" so that tools such as emacs's "M-x
1211 compile" does not mistake the output as containing a compiler error.
1213 Export two new functions from libext2fs: ext2fs_extent_node_split()
1214 and ext2fs_extent_goto2().
1216 The ext2fs_extents_fix_parents() was fixed so it does not modify the
1217 location of the extent handle if its current location is at an
1218 interior node, rather than a leaf node of an inode's extent tree.
1220 Add a regression test to assure that e2fsck can correctly fix an
1221 inconsistent interior node in an inode's extent tree.
1223 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
1224 correctly support bigalloc file systems which use store block usage
1225 information in units of clusters.
1227 Fixed the help text in the configure script for --enable-quota.
1229 The m68k-specific bitops code has been removed since they were
1230 incorrectly treating bit numbers with the high bit set as signed
1231 integers. Furthermore, modern compilers do a good enough job
1232 optimizing the generic code there is no point in having the m68k
1233 specific asm statements.
1235 Fixed how we link the test programs so they always use the static
1236 libraries, so that we test using the libraries which we have just
1239 Update config.guess and config.sub to the latest versions from the GNU
1242 Fixed the com_err.texinfo file so that it can produce a valid
1243 postscript/pdf printed output.
1245 Add a regression test which checks debugfs's ability to create
1246 symlinks, named FIFO's, and device nodes.
1248 Add a function ext2fs_symlink(), which creates symlinks to the
1251 Add debugging code so we can test old kernel interfaces for online
1252 resize to resize2fs. This backwards compatibility checking is keyed
1253 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
1254 test the functionality of the kernel's older resize ioctls without
1255 needing to install an old version of resize2fs, and to also test a
1256 modern resize2fs's ability to work with older kernels without having
1257 to install an older version of the kernel.
1260 E2fsprogs 1.42.6 (September 21, 2012)
1261 =====================================
1263 When mke2fs creates file systems with lazy itable initialization, the
1264 progress updates for writing the inode table happens so quickly that
1265 on a serial console, the time to write the progress updates can be the
1266 bottleneck. So mke2fs will now only update its progress indicators
1269 Resize2fs will skip initializing the inode tables if the kernel
1270 supports lazy_itable_init, which speeds up growing off-line growth of
1271 uninit_bg file systems significantly. Resize2fs will now also
1272 correctly set the itable_unused field in the block group descriptor to
1273 speed up the first e2fsck after the file system is grown.
1275 Resize2fs has been fixed so that on-line resizing of meta_bg file
1276 systems work correctly. This is needed to grow file system which are
1279 Resize2fs will now correctly handle resizing file systems to 16TB on
1280 32-bit file systems when "16TB" is specified on the command line.
1282 Fix mke2fs so that it will be careful to set the reserved blocks ratio
1283 larger than 50%; this can happen when creating small file systems and
1284 when the last block group is dropped because there are not enough
1285 blocks to support the metadata blocks in the last block group.
1287 Fixed spelling mistake in debugfs's help message.
1289 Fixed a potential seg fault in e2fsck when there is an I/O error while
1290 reading the superblock.
1292 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
1294 Updated/fixed various man pages. (Addresses Sourceforge Bug:
1300 The configure option --enable-relative-symlink was broken so that it
1301 needed to be --enable-symlink-relative-symlinks. We will support both
1302 for at least two years, but then the worng configure option will be
1305 Fixed a regression introduced in 1.42.5 so the link order for
1306 e2fsprogs' libraries will be correct for both static and shared
1307 linking. (Addresses Sourceforge Bug: #3554345)
1309 Add support for e2fsprogs to be compiled using clang/LLVM.
1311 Fix portability problems on non-Linux systems: avoid compile failures
1312 on systems that don't have malloc.h
1314 Fix f_mmp regression test suite so that debugfs gets killed if the
1315 test is interrupted.
1319 E2fsprogs 1.42.5 (July 29, 2012)
1320 ================================
1322 Fixed a bug with mke2fs where if there is only 8 inodes per block
1323 group, the calculation of the number of uninitialized inodes in the
1324 first block group would go negative. This resulted in "mke2fs -N 256
1325 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
1326 would run out of space. (Addresses Sourceforge Bug: #3528892)
1328 Fixed a bug in how e2fsck would uniquify directory entry names.
1329 (AddressesSourceforge Bug: #3540545)
1331 Previously, e2fsck would only allow a mounted file system to be
1332 checked if it was the root file system and it was mounted read-only.
1333 Now it will allow any file system mounted read-only to be checked if
1334 the -f option is specified. This makes it easier to test how e2fsck
1335 handles checking file systems which are mounted without having to test
1336 on the root file system.
1338 Fixed a problem if e2fsck where if the root file system is mounted
1339 read-only, e2fsck would not clear an error indication in the journal
1340 superblock. Combined with a kernel bug, this would cause the e2fsck
1341 to check the file system after every single boot.
1343 The e4defrag program can now handle device symlinks, such as
1344 /dev/mapper/testvg-testlv, instead of insisting on a less
1345 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
1348 Fixed filefrag so it will not crash with a segfault on files from a
1349 virtual file system such as /proc. (e.g., "filefrag
1352 Fixed filefrag so that it correctly reports the number of extents.
1353 (Addresses Red Hat Bugzilla: #840848)
1355 Fixed a file descriptor leak in logsave which could cause it to hang.
1356 (Addresses Debian Bug: #682592)
1358 Fixed e2fsck so that the file system is marked as containing an error
1359 if the user chooses not to fix the quota usage information.
1361 Fixed tune2fs so that it correctly removes the quota feature when the
1362 last quota inode is removed.
1364 Fix tune2fs so that after removing a quota inode, the block bitmap is
1365 updated; otherwise, e2fsck would complain after running 'tune2fs -O
1368 Fix tune2fs so that when converting a file system from using legacy
1369 quota files to the new quota file system feature with hidden quota
1370 files, the accounting for these files is handled correctly so that
1371 e2fsck doesn't complain.
1373 Improved e2fsck's verbose reporting statistics, and allow the more
1374 verbose reporting to be enabled via /etc/e2fsck.conf.
1376 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
1378 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
1384 Fixed portability problems on other operating systems (e.g., Hurd and
1385 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
1387 Make sure that shared libraries link with the shared libraries built
1388 in the build tree, instead of the system provided libraries.
1389 Previously, libraries and executables were linked with the system
1390 libraries if present, and possibly using static archives instead of
1391 shared libraries. This was also problematic since if libext2fs.so is
1392 linked with a static libcom_err.a from system, the build system would
1393 attempt to link without -lpthread. (Addresses Sourceforge Bug:
1397 E2fsprogs 1.42.4 (June 12, 2012)
1398 ================================
1400 Fixed more 64-bit block number bugs (which could end up corrupting
1401 file systems!) in e2fsck, debugfs, and libext2fs.
1403 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
1404 not properly propagating the journal's s_errno field to the superblock
1405 field; it was not checking this field if the journal had already been
1406 replayed, and if the journal *was* being replayed, the "error bit"
1407 wasn't getting flushed out to disk.
1409 Fixed a false positive complaint by e2fsck if all of the extents in
1410 the last extent tree block are uninitalized and located after the end
1411 of the file as defined by i_size.
1413 The dumpe2fs will now display the journal's s_errno field if it is
1414 non-zero, and it will also display the journal's 64-bit feature flag
1417 Fix e2fsck so that it always opens the device file in exclusive mode
1418 when it might need to modify the file system, and never if the -n
1419 option is specified. (Previously, there were a few corner cases where
1420 it might get things wrong in either direction.)
1422 E2fsck now correctly truncates or deallocates extent-mapped inodes on
1423 the orphan list. The root cause was a bug in libext2fs's block
1424 iterator which could end up skipping an extent when the last block in
1425 an extent is removed, causing the current extent to be removed from
1428 E2fsck now correctly sets the global free block and inode counts when
1429 truncating or removing inodes on the orphan list in preen mode.
1430 Previously, it would leave these values would be set incorrectly,
1431 which is largely a cosmetic issue since the kernel no longer pays
1432 attention to those fields, but it can cause spurious complaints in
1433 subsequent e2fsck runs.
1435 Fix i_blocks accounting when the libext2fs library needs to add or
1436 remove an extent tree block on bigalloc file systems.
1438 The lsattr and chattr programs now support the No_COW flag for the
1441 Debugfs now interprets date strings of the form @ddd as ddd seconds
1442 after the beginning of the epoch. This is handy when setting an inode
1443 number into the d_time field when debugging orphan list handling.
1445 Fix a precedence bug with built-in quota support which might result in
1446 e2fsck paying attention to the quota inode field even if the built-in
1447 quota feature flag is not set. Fortunately, in practice that
1448 superblock field should be zero for non-built-in quota file systems,
1449 so it's unlikely this bug would have caused problems.
1451 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
1457 The regression test suite can now run the integration tests in the
1458 tests directory in parallel, via "make -jN check".
1460 Add new test, f_zero_extent_length which tests e2fsck's handling of
1461 the case where all of the extents in the last extent tree block are
1462 uninitialized extents after i_size.
1464 Add a new test, f_jnl_errno, which checks handling of an error
1465 indication set in the journal superblock.
1467 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
1468 of a 64-bit journal.
1470 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
1471 tests e2fsck's handling of orphan inodes in preen mode, and truncation
1472 of extent inodes on the orphan list.
1474 Fixed more OS X portability issues.
1477 E2fsprogs 1.42.3 (May 14, 2012)
1478 ===============================
1480 Fix a bug in the Unix I/O manager which could cause corruption of file
1481 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
1482 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
1483 dumpe2fs to incorrectly display block numbers > 32-bits.
1485 Improve the support for integrated quota files (where quota is a first
1486 class supported feature using hidden files in the ext4 file system).
1487 Previously the quota file was getting rewritten even when it was not
1488 necessary, and e2fsck would erroneously try to hide quota files which
1489 were already hidden.
1491 Quiet complaints in e2fsck when the total free blocks or inodes are
1492 incorrect in the superblock after an system crash, since we don't
1493 update nor depend on the superblock summaries at each commit boundary.
1495 Fixed a regression introduced in 1.42.2 which would cause applications
1496 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
1497 would were still using the legacy 32-bit bitmaps) to crash. This was
1498 due to missing 32-bit compat code in side the function
1499 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
1502 Fix a bug which would cause mke2fs to fail creating the journal if
1503 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
1506 Updated/fixed various man pages.
1508 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
1511 Fixed various Debian Packaging issues.
1517 Change the nonsensically wrong types in the function signature of the
1518 inline function ext2fs_find_first_zero_block_bitmap2(). This was
1519 caused by a cut and paste error; fortunately no code in e2fsprogs used
1520 this inline function, and there are any users of this functions
1521 outside of e2fsprogs.
1523 Add support for systems which have valloc(), but which do have
1524 posix_memalign() nor memalign() (such as MacOS 10.5).
1526 Refactor and clean up the allocation of aligned buffers for Direct I/O
1527 support. Previously some allocations were requesting a greater
1528 alignment factor that what was strictly necessary. Also optimize
1529 reading and writing bitmaps using Direct I/O when the size of the
1530 bitmap did not fully cover the file system blocksize.
1532 Reserve the codepoints for the INCOMPAT features LARGEDATA and
1535 Improved the regression test suite by adding some new integration
1536 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
1537 jbd2 format, as well as f_eofblocks which tests the new handling of
1538 uninitialized and initialized blocks beyond i_size. Also add a new
1539 unit test which verifies 32-bit bitmaps support and the new
1540 find_first_zero primitives.
1542 Add a few dependencies to fix parallel (make -j) builds.
1544 Removed bash'isms which were breaking the regression test suite on
1545 systems where /bin/sh is not bash.
1547 The config.guess and config.sub have been updated to the 2012-02-10
1550 Fix a portability problem caused by assuming the present of mntent.h
1551 means that setmntent() exists. Instead, explicitly test for this in
1552 the configure script.
1554 If the sys/signal.h header file does not exist, don't try to include
1555 it, since it's not available on all systems.
1557 Add support for systems that do not support getpwuid_r()
1559 The configure script now supports a new option,
1560 --enable-relative-symlinks, which will install relative symlinks for
1561 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
1563 When building BSD shared libraries make sure the LDFLAGS variable is
1564 passed to the linker. Fixing this allows, for example, e2fsprogs to
1565 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
1568 Fix gcc -Wall nitpicks
1571 E2fsprogs 1.42.2 (March 27, 2012)
1572 =================================
1574 The resize2fs program uses much less CPU and is much faster for very
1575 large file systems. (Addresses Debian Bug: #663237)
1577 The seti and freei commands in debugfs can now take an optional length
1578 argument to set and clear a contiguous range of inodes.
1580 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
1581 plan to remove support for it from the kernel file system driver. It
1582 really wasn't very useful and was causing more problems than it
1583 solves. Since e2fsck will complain if inodes that should have
1584 EOFBLOCKS_FL do not have the flag set, we are going to remove this
1585 check from e2fsprogs first, and then only remove the flag from the
1588 The mke2fs program can now use direct I/O via "mke2fs -D". This will
1589 slow down the mke2fs, but it makes it more polite on a loaded server
1590 by limiting the amount of memory that gets dirtied by mke2fs when it
1591 is using buffered I/O.
1593 E2fsck was needlessly closing and re-opening the file system as a side
1594 effect of adding Multiple Mount Protection (MMP). This isn't
1595 necessary for non-MMP file systems, so drop it.
1597 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
1598 can more easily diagnose memory allocation failures caused by
1599 insufficient memory. E2fsck will now abort if there are memory
1600 allocation failures when the file system is initially opened and
1601 during the block group descriptor checks. (Addresses Google Bug:
1604 If there are incorrect block group checks, e2fsck will now report the
1605 incorrect and corrected checksum values.
1607 The e2fsck progam can now write log files containing the details of
1608 the problems that were found and fixed directly, via configuration
1609 parameters in /etc/e2fsck.conf.
1611 Added the ability to limit the number of messages reported by e2fsck
1612 for a given problem type. This avoids a potential bottleneck if there
1613 is a serial console which can cause a boot sequence to take a long
1614 time if e2fsck needs to report many, many file system errors.
1616 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
1617 them to use much less memory for large file systems.
1619 The dumpe2fs program will now print the expected block group checksum
1620 if it is incorrect. This helps to diagnose problems caused by
1621 incorrect block group checksums.
1623 E2fsck now checks for extents with a zero length, since the kernel
1624 will oops if it comes accross such a corrupted data structure. (See
1625 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
1627 E2fsck has a number of bugs relating to discard that have been fixed.
1628 (1) Fixed a bug which could cause e2fsck to discard portions of the
1629 inode table which were actually in use. (2) E2fsck will now avoid
1630 using discard if the block device doesn't zero data on discard, since
1631 otherwise this could cause problems if the file system gets corrupted
1632 in the future. (3) E2fsck will now avoid using discard when it is run
1633 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
1634 discards in the last block group.
1636 E2fsck's CPU utilization in pass 5 has been optimized, which will
1637 speed up e2fsck slightly.
1639 E2image will now skip copying uninitialized bitmap and inode table
1642 Fixed mke2fs -S so it does not corrupt the first block group's
1645 E2fsck will now check the new sysfs interface to determine if we are
1646 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
1648 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
1650 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
1655 Fixed various portability issues for non-Linux systems, particularly
1656 MacOS X, as well as Linux systems running with the just-released glibc
1659 Fix file descriptor leak in ext2fs_close() if the file system with
1660 uninit_bg is opened read/only with a backup superblock. (Addresses
1661 SourceForge Bug: #3444351)
1663 Fixed an invalid return in a non-void function in the quota code.
1664 (Addresses SourceForge Bug: #3468423)
1666 Fixed the debian rules file so that the calls to dpkg-buildflags works
1667 when the shell is dash.
1669 The debian package build now uses V=1 so that there is more
1670 information about potential build failures in debian buildd logs.
1672 If the uninit flags get cleared by functions such as
1673 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
1674 superblock is marked dirty and the block group descriptor checksum is
1675 updated if necessary.
1677 The debian rules file will now try to load debian/rules.custom of it
1678 exists. This flie can skip various builds for speed reasons if there
1679 is no need for the e2fsck-static or udeb packages. Available
1680 customizations in the rules file includes SKIP_STATIC=yes,
1681 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
1683 In addition, if the file misc/mke2fs.conf.custom.in exists in the
1684 source tree, it will be used instead of the standard misc.conf file in
1685 the upstream sources. This makes it easier for Debian-derived systems
1686 to distribute a custom mke2fs.conf file without having to worry about
1687 merge issues if future versions of e2fsprogs makes changes in the
1688 upstream default version of mke2fs.conf.
1691 E2fsprogs 1.42.1 (February 17, 2012)
1692 ===================================
1694 The mke2fs and e2fsck now use significantly less memory when creating
1695 or checking very large file systems. This was enabled by adding
1696 extent-based bitmaps which are stored using a red-block tree, since
1697 block and inode allocations tend to be contiguous.
1699 The command mke2fs -S is used as a last ditch recovery command to
1700 write new superblock and block group descriptors, but _not_ to destroy
1701 the inode table in hopes of recovering from a badly corrupted file
1702 system. So if the uninit_bg feature is enabled, mke2fs -S will now
1703 set the unused inodes count field to zero. Otherwise, e2fsck -fy
1704 after using mke2fs -S would leave the file system completely empty.
1706 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
1707 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
1708 installed an mke2fs binary using that name.
1710 The usage and help messages for the -G, -t and -T options in mke2fs
1713 If e2fsck needs to use the backup group descriptors, the
1714 ext2fs_open2() function clears the UNINIT bits to ensure all of the
1715 inodes in the file systems get scanned. However, the code which reset
1716 the UNINIT flags did not also recalculate the checksum, which produced
1717 many spurious (and scary) e2fsck messages. This has been fixed by
1718 resetting cheksums when the UNINIT bits are cleared.
1720 Relax a check in e2fsck which required that the block bitmap to be
1721 initialized when the inode bitmap is in use. This will allow us to
1722 eventually eliminate code from the kernel which forcibly initialized
1723 the block bitmap when the inode bitmap is first used, requiring an
1724 extra journal credit and disk write. (Addresses Google Bug: #5944440)
1726 Make sure rdebugfs (which may be installed setuid or setgid disk) does
1727 not honor environment variables if euid != uid or egid != gid.
1729 Debugfs's ncheck command has been optimized and now is much more
1730 robust with faced with corrupted file systems. The ncheck command
1731 also now has a -c option which will verify the file type information
1732 in the directory entry to see if matches the inode's mode bits. This
1733 is extremely useful when trying to use debugsfs to determine which
1734 parts of the file system metadata can be trusted.
1736 E2image will try to use ftruncate64() to set the i_size for raw
1737 images, instead of writing a single null byte. This avoid allocating
1738 an extra block to the raw image, for those file systems and/or
1739 operating systems that support this. (Linux does.) In addition, fix
1740 a logic bug that caused the file to not be properly extended if the
1741 size of the last hole was exactly an multiple of a megabyte.
1743 Fixed a bug in resize2fs where for 1k and 2k file systems, where
1744 s_first_data_block is non-zero, this wasn't taken into account when
1745 calculate the minimum file system size for use with the -M option.
1747 Fixed the badblocks program to honor the -s flag when in read-only -t
1748 mode. (Addresses Debian Bug #646629)
1750 Update Czech, Dutch, French, Polish, and Sweedish translation from the
1751 Translation Project.
1753 Fixed various Debian Packaging issues so that dpkg-buildflags is used
1754 if present, which allows e2fsprogs to be built with security hardening
1755 flags. (Addresses Debian Bugs: #654457)
1760 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
1761 This was only an issue for programs compiled against e2fsprogs 1.41
1762 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
1765 The libext2fs library now uses sysconf() to fetch the page size, instead
1766 of the deprecated getpagesize().
1768 The ext2fs_get_pathname() function will return a partial path if an a
1769 directory in the path is not a directory, displaying it as an inode
1770 number in angle brackets instead of giving up and displaying an error.
1771 This is much more helpful when a user is trying to debug a corrupted
1774 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
1776 Added a new library function, ext2fs_file_get_inode_num(), for use by
1779 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
1780 file, it actually works.
1782 The block iterator now properly honors the BLOCK_ABORT flag for
1783 extent-based flags. Previously, it didn't, which generally made code
1784 be less efficient, but it could cause bugs in ext2fs_link(), for
1785 example, by causing it to insert multiple directory entries.
1787 Fixed an (harmless other than causing a compiler warning) use of an
1788 uninitialized variable in e2fsck's MMP code.
1791 E2fsprogs 1.42 (November 29, 2011)
1792 ==================================
1794 This release of e2fsprogs has support for file systems > 16TB. Online
1795 resize requires kernel support which will hopefully be in Linux
1796 version 3.2. Offline support is not yet available for > 16TB file
1797 systems, but will be coming.
1799 This release of e2fsprogs has support for clustered allocation. This
1800 reduces the number of block (now cluster) bitmaps by allocating and
1801 deallocating space in contiguous power-of-2 collections of blocks,
1802 which are called clustered. This is a file system level feature,
1803 called 'bigalloc', which must be enabled when the file system is
1804 initially formatted. It is not backwards compatible with older
1807 Added support for the Multi-Mount Protection (MMP) feature.
1809 E2fsck more efficiently uses scratch files for really big file
1810 systems. (This is a feature that has to be turned on explicitly; see
1811 [scratch_files] in the e2fsck.conf man page.)
1813 Fix a bug in e2fsck where if the free blocks and inodes counts are
1814 incorrect, e2fsck would fix them without printing an error message.
1815 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
1816 any explanation of what was fixed.
1818 E2fsck will no longer attempt to clone an extended attribute block in
1819 pass1b handling if the file system does not support extended
1822 E2fsck will be more careful accidentally asking the user to continue
1823 if the file system is mounted, so that an escape sequence won't cause
1824 a false positive. (Addresses Debian Bug: #619859)
1826 E2fsck now uses less cpu time in pass 5 when large portions of the
1827 bitmaps are uninitialized.
1829 E2fsck will no longer segault when a corrupted file system has a bad
1830 extent, and removing it leads to a block needing to be deallocated.
1831 (Addresses SourceForge Bug: #2971800)
1833 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
1834 and print debugging information to make it easier to find potential
1837 E2fsck will check to see if the bad block inode looks insane, and will
1838 skip trying to use if it certain fields which should be zero look
1839 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
1840 to get confused and do more harm than good.
1842 If e2fsck modifies certain superblock fields which the kernel doesn't
1843 look at, it will now mark the superblock as dirty without marking the
1844 file system as changed. This avoids signalling the init scripts that
1845 a reboot is necessary, since the kernel isn't going to look at those
1846 fields, so it won't care if they have been changed.
1848 Fixed a bug in the libext2fs library (in the binary search routine of
1849 the icount abstraction) that could (very, very rarely) cause e2fsck to
1850 die in the middle of pass 1 or pass 2 processing.
1852 E2fsck will not try to do a discard operation if the -n option was
1853 specified on the command line.
1855 E2fsck now supports an extended "discard" option which will cause
1856 e2fsck to attempt discard all unused blocks after a full, successful
1859 E2fsck will check for the bad block inode to make sure it looks sane
1860 before trusting it, to avoid causing more harm than good to the file
1863 E2fsck now returns additional status bits in its exit code if it
1864 aborts early in the e2fsck run.
1866 E2fsck now correctly calculates the maximum file size in the case of
1867 the huge_file file system feature enabled without extents.
1869 The mke2fs and e2fsck programs now tries to use the punch hole command
1870 as a "discard" when operating on normal files.
1872 The e2image program now supports the qcow2 format, which is a more
1873 efficient way of capturing file system dumps.
1875 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
1876 per-device defaults to be specified in the configuration file.
1878 Mke2fs now supports the reserved_ratio relation in the [defaults] and
1879 [fs_types] section in mke2fs.conf.
1881 Mke2fs now creates extent-mapped directories for the root and
1882 lost+found directories.
1884 Mke2fs will skip zero'ing the journal if the extended option
1885 "lazy_journal_init" is specified. This can save a lot of time, but it
1886 does add a small amount of risk if the system crashes before the
1887 journal is overwritten entirely once. It is epsecially useful for
1890 Mke2fs will now create file systems that enable user namespace
1891 extended attributes and with time- and mount count-based file
1892 system checks disabled.
1894 Mke2fs will not set a stride or strip size of one block based on block
1895 device attributes obtained from sysfs.
1897 Mke2fs now displays a progress report during the discard process.
1899 Mke2fs now handles extreme file system parameters correctly which
1900 previously caused the inodes per group to drop below 8, leading to a
1901 segfault. (The inodes per group must be a multiple of 8, but the code
1902 didn't correctly deal with an inodes per group count less than 8.)
1904 Mke2fs and tune2fs previously would give an error if the user tried
1905 setting the stride and stripe-width parameters to zero; but this is
1906 necessary to disable the stride and stripe-width settings. So allow
1907 setting these superblock fields to zero. (Addresses Google Bug:
1910 Mke2fs now gives a warning if the auto-detected block size exceeds the
1913 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
1914 is the default), mke2fs will now set the s_max_mnt_count superblock
1915 field to -1, instead of 0. Kernels older then 3.0 will print a
1916 spurious message on each mount then they see a s_max_mnt_count set to
1917 0, which will annoy users. (Addresses Debian Bug: #632637)
1919 The default mke2fs.conf now has entries for "big" and "huge", which
1920 are needed for very big file systems.
1922 The resize2fs program now has support for a new online resize ioctl
1923 that can support file systems > 16TB, once it arrives in v3.x kernels.
1925 Fixed bug which caused resize2fs to fail when shrinking an empty file
1926 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
1928 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
1930 Allow tune2fs to remove external journals if the device can not be
1933 Debugfs's icheck will now correctly find inodes which use the
1934 searched-for block as an extended attribute block.
1936 Debugfs now has a new "punch" command which remove blocks from the
1939 Debugfs now has a new "e2freefrag" command which analyzes the free
1940 space fragmentation of the file system, using the same code as the
1943 Debugfs now has a "filefrag" command which displays information about
1944 a file's fragmentation.
1946 Add support to build a metadata-only, read-only, stripped-down version
1947 of debugfs called rdebugfs.
1949 Fixed a potential stack overrun bug in debugfs.
1951 The badblocks program now correctly recovers from I/O errors when
1952 direct I/O is being used. The badblocks command now also supports a
1953 -B option which forces the use of buffered I/O, and the -v option will
1954 provide a more detailed breakdown of read, write, and failed
1957 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
1959 Added support for journals larger than 2GB.
1961 Support using both hard links and symlinks when installing e2fsprogs.
1963 Add overflow checking to tune2fs -i's fsck interval, which must fit in
1966 The debugfs command now has a new 'blocks' command which prints out
1967 data blocks of a particular inode in a format which is useful for
1970 Filefrag will report 0 extents correctly in verbose mode. (Addresses
1971 RedHat Bugzilla: #653234)
1973 Filefrag has been fixed so its -v report prints the correct expected
1974 block number (previously there had been an off-by-one error). In
1975 addition, it will now display the number of contiguous extents when -v
1976 is not specified. This makes it consistent with the number of extents
1977 printed when the -v option was specified. In addition, the number of
1978 contiguous extents is far more interesting/useful than the number of
1979 physical extents for very large files. (Addresses Debian Bug:
1982 Logsave's usage message has been fixed. (Addresses Debian Bug:
1985 Avoid an infinite loop in ext2fs_find_block_device() if there are
1986 symlink loops in /dev caused by a buggy udev.
1988 Added a useful "fallocate" program to the contrib directory.
1990 Fixed an ABI compatibility problem in libext2fs which broke the dump
1991 program. Also added back some macros which dump needed so it could
1992 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
1995 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
1996 Debian Bug: #641667)
1998 Added internationalization support for libcom_err error table strings.
2000 Fixed various spelling mistakes found in various output strings found
2001 by I18N translators.
2003 Update translations: French, Chinese, Germany, Indonesian, Swedish,
2004 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
2007 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
2008 #614662, #632169, #641838, #627535, #629355)

2016 Initial support for quota as an integrated feature, where the quota
2017 files are hidden system files that are automatically maintained by
2018 e2fsck is present, although disabled by default. It must be enabled
2019 by using the configure option --enable-quota.
2021 Reserved the on-disk fields for the metadata checksum and snapshot
2022 features, which are currently in development.
2024 The ext2fs library now has the new functions ext2fs_punch(),
2025 ext2fs_get_memzero() and ext2fs_file_get_inode().
2027 The ext2fs library now has support for calculating the crc32c checksum
2028 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
2030 The I/O manager now supports the discard operation.
2032 Reserved file system code points for new 1st class quota feature.
2034 Shortened the compilation lines by moving the autoconf defines to
2035 a config.h header file.
2037 Fixed a potential free of an unitialized pointer in
2038 ext2fs_update_bb_inode().
2040 Fixed miscellaneous gcc -Wall and coverity warnings.
2042 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
2044 Fixed a build failure when OMIT_COM_ERR is defined.
2046 Improved error checking and fixed memory leaks caused by error return
2049 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
2050 the fsync() to be skipped.
2052 Added a test for extent-mapped journals by mke2fs and tune2fs.
2054 Added a test for creating a large (over 4GB) journal using mke2fs.
2056 Added a test to make sure the inode size remains constant.
2058 The regression test script now prints the list of which tests failed.
2060 The regression test system now uses /tmp for its scratch files, which
2061 is often a tmpfs mounted file system and hence much faster.
2063 The i_e2image test was fixed so it works with valgrind.
2065 Tests that rely on debugfs are now skipped if debugfs wasn't built.
2067 Fixed the dependencies for "make check" so all required dependencies
2068 are built before running the gression tests.
2070 A link to com_err.h is installed in $(includedir) during a "make install".
2072 The po/*.gmo files are automatically rebuilt if they are missing or
2073 out of date. This helps out Debian packaging.
2075 Allow ext2fs_get_memalign() to compile on systems that don't have
2078 Fixed a namespace leak in libext2fs (tdb_null).
2081 E2fsprogs 1.41.14 (December 22, 2010)
2082 =====================================
2084 Fix spurious complaint in mke2fs where it would complain if the file
2085 system type "default" is not defined in mke2fs.conf.
2087 The resize2fs program will no longer clear the resize_inode feature
2088 when the number reserved group descriptor blocks reaches zero. This
2089 allows for subsequent shrinks of the file system to work cleanly for
2090 flex_bg file systems.
2092 The resize2fs program now handles devices which are exactly 16T;
2093 previously it would give an error saying that the file system was too
2096 E2fsck (and the libext2fs library) will not use the extended rec_len
2097 encoding for file systems whose block size is less than 64k, for
2098 consistency with the kernel.
2103 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
2104 been fixed. (Addresses Sourceforge Bug: #3138115)
2106 The ext2fs_block_iterator2() function passed an incorrect ref_offset
2107 to its callback function in the case of sparse files. (Addresses
2108 Sourceforge Bug: #3081087)
2110 Fix some type-punning warnings generated by newer versions of gcc.
2113 E2fsprogs 1.41.13 (December 13, 2010)
2114 =====================================
2116 E2fsck now supports the extended option "-E journal_only", which
2117 causes it to only do a journal replay. This is useful for scripts
2118 that want to first replay the journal and then check to see if it
2121 E2fsck will now support UUID= and LABEL= specifiers for the -j option
2122 (which specifies where to find the external journal). (Addresses
2125 E2fsck now has support for the problems/<problem code>/force_no
2126 configuration option in e2fsck.conf, which forces a problem to not be
2129 Dumpe2fs will now avoid printing large negative offsets for the bitmap
2130 blocks and instead print a message which is a bit more helpful for
2131 flex_bg file systems.
2133 Mke2fs will now check the file system type (specified with the -t
2134 option) to make sure it is defined in the mke2fs.conf file; if it is
2135 not, it will print an error and abort. If the usage type (specified
2136 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
2137 warning but will continue. (Addresses Debian Bug #594609)
2139 Clarified error message from resize2fs clarifying that on-line
2140 shrinking is not supported at all. (Addresses Debian Bug #599786)
2142 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
2143 displayed. (Addresses Debian Bug #555456)
2145 E2fsck will open the external journal in exclusive mode, to prevent
2146 the journal from getting truncated while it is in use due to a user
2147 accidentally trying to run e2fsck on a snapshotted file system volume.
2148 (Addresses Debian Bug #587531)
2150 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
2153 The tune2fs program can now set the uninit_bg feature without
2156 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
2157 default mount options settings which were added in 2.6.35.
2159 The e2fsck and dumpe2fs programs now support the new ext4 superblock
2160 fields which track where and when the first and most recent file
2161 system errors occurred. These fields are displayed by dumpe2fs and
2162 cleared by e2fsck. These new superblock fields were added in 2.6.36.
2164 Debugfs now uses a more concicse format for listing extents in its
2165 stat command. This format also includes the interior extent tree
2166 blocks, which previously was missing from stat's output for
2169 Debugfs has a new option, -D, which will request Direct I/O access of
2172 Mke2fs will skip initializing the inode table if a device supports
2173 discard and the discard operation will result in zero'ed blocks.
2175 Badblocks will now correctly backspace over UTF-8 characters when
2176 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
2177 Debian Bugs #583782 and #587834)
2179 E2freefrag will now display the total number of free extents.
2181 Resize2fs -P no longer requires a freshly checked filesystem before
2182 printing the minimum resize size.
2184 Fixed a floating point precision error in a binary tree search routine
2185 that can lead to seg fault in e2fsck and resize2fs.
2187 Fixed a bug in e2fsck where if both the original and backup superblock
2188 are invalid in some way, e2fsck will fail going back to the original
2189 superblock because it didn't close the backup superblock first, and
2190 the exclusive open prevented the file system from being reopened.
2192 Fixed a big in e2freefrag which caused getopt parsing to fail on
2193 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
2195 Clarified an mke2fs error message so a missed common in an -E option
2196 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
2197 results in a more understandable explanation to the user.
2199 Mke2fs now displays the correct valid inode ratio range when
2200 complaining about an invalid inode ratio specified by the user.
2202 Mke2fs now understands the extended option "discard" and "nodiscard",
2203 and the older option -K is deprecated. The default of whether
2204 discards are enabled by default can be controled by the mke2fs.conf
2207 Mke2fs's handling of logical and physical sector sizes has been
2208 improved to reflect the fact that there will be some SSD's with 8k and
2209 16k physical sectors arriving soon. Mke2fs will no longer force block
2210 size to be the physical sector size, since there will be devices where
2211 the physical sector size is larger than the system's page size, and
2212 hence larger than the maximal supported block size. In addition, if
2213 the minimal and optimal io size are not exported by the device, and
2214 the physical sector size is larger than the block size, the physical
2215 sector size will be used to set the Raid I/O optimization hints in the
2218 E2fsck will now display a better, more specific error message when the
2219 user enters a typo'ed device name, instead of blathering on about
2220 alternate superblocks.
2222 Fixed various Debian Packaging Issues
2224 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
2225 #589345, #591083; Addresses Launchpad Bug: #505719)
2227 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
2228 Polish, Swedish, and Vietnamese translations.
2234 Fix a dependency definition for the static and profiled blkid
2235 libraries which could cause compile failures in some configurations.
2236 (Addresses Debian Bug: #604629)
2238 Add support for Direct I/O in the Unix I/O access layer.
2240 Fixed a memory leak in the Unix I/O layer when changing block sizes.
2242 Fixed minor memory leaks in mke2fs.
2244 Added a new function to the ext2fs library, ext2fs_get_memalign().
2246 The tst_super_size test program will check to make sure the superblock
2247 fields are correctly aligned and will print them out so they can be
2248 manually checked for correctness.
2250 Fixed some makefile dependencies for test programs in lib/ext2fs.
2252 Reserved the feature flags and superblock fields needed for the Next3
2255 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
2256 EXT4_INCOMPAT_EA_INODE.
2259 E2fsprogs 1.41.12 (May 17, 2010)
2260 ================================
2262 Mke2fs now gives a correct error message if the external journal
2263 device is not found. (Addresses Red Hat Bug #572935)
2265 Resize2fs -P will now refuse to print a minimum size if the file
2266 system is not clean. Previously it would go ahead and print a minimum
2267 size anyway, which might not be correct, leading to user confusion.
2269 E2fsck now tests for extents that begin at physical block 0 and
2270 rejects them as invalid. (Addresses Google Bug: #2573806)
2272 Fixed a bug in e2fsck which could cause it to crash when trying to
2273 remove an invalid extent and the block bitmaps hadn't yet been loaded.
2274 (Addresses SourceForge Bug: #2971800)
2276 E2fsck now will completely skip time-based checks if the system clock
2277 looks insane or the option broken_system_clock is set in
2280 E2fsck would previously report an i_blocks corruption for a 4T file
2281 created using posix_fallocate; this bug has been fixed.
2283 E2fsck will now correctly mark a sparse journal as invalid and will
2284 delete and recreate the journal to address the problem.
2286 E2fsck would previously incorrectly ask the user whether she would
2287 like to abort the file system check after finding a problem --- and
2288 then abort regardless of the user's answer. This is annoying, and
2291 E2fsck can now continue even if it fails to recreate the resize
2292 inode; previously it would just abort the file system check
2295 E2fsck could potentially remove directory entries for inodes found in
2296 the unused region of the inode table; this would generally happen on
2297 ext4 file systems that do not use journaling. This bug has been fixed
2298 by not clearing these directory entries once it has been established
2299 that bg_unused_inodes may not be trustworthy; once pass #2 has been
2300 completed, e2fsck will restart the file system check from the
2301 beginning, and then it will be safe to delete any directory entries
2302 pointing to inodes that appear to be deleted. (Addresses Google Bug:
2305 E2fsck will not try to set the block group checksums if the user
2306 cancels the fsck with a control-C. It's a bad idea to set the
2307 checksums if e2fsck hasn't been completed, and it often results an the
2308 error message, "Inode bitmap not loaded while setting block group
2309 checksum info". (Addresses Launchpad Bug: #582035)
2311 The mke2fs program now queries the kernel for the physical as well as
2312 the logical sector size, and will not allow a blocksize below the
2313 logical, and will strongly encourage a blocksize at least as big as
2314 the physical blocksize. This is needed for 4k sector drives that
2315 emulate 512 byte sector sizes.
2317 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
2318 rarely needed, but it is a legal value.
2320 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
2321 not needed, and offer to clear it; this is a sign of a kernel bug, but
2322 more importantly, some released kernels may crash when this situation
2323 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
2325 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
2326 i_size is correct. (Kernels starting with 2.6.34 will set

2335 Fixed various Debian packaging issues --- see debian/changelog for
2336 details. (Addresses Debian Bugs: #571247, #563487)
2342 The regression test suite now uses its own mke2fs.conf file, so that
2343 downstream distributions want change the mke2fs.conf file which is
2344 distributed in the RPM or dpkg file, without worrying about screwing
2345 up the regression test results.
2347 Always build namei.o so that building with configure --disable-debugfs
2348 works correctly. Long-term, if we care about reduced e2fsprogs
2349 builds, we need a more general solution for deciding what .o files are
2350 needed for a particular build. Given that install floppies are going
2351 (gone?) the way the dodo bird, we probably don't care, though.
2352 (Addresses Sourceforge Bug: #2911433)
2354 Add configure options --enable-symlink-build and
2355 --enable-symlink-install, which allow e2fsprogs be built using
2356 symlinks instad of hard links, and to be installed using symlinks
2357 instead of hard links, respectively. It is useful when the file
2358 system where the build is taking place, or the file system where
2359 e2fsprogs is installed, can't handle hard links for some reason.

2376 E2fsck now prints a much more emphatic and hopefully scary message
2377 when a file system is detected as mounted while doing a read/write
2378 check of the filesystem. Hopefully this will dissuade users from
2379 thinking, "surely that message doesn't apply to *me*" :-(
2381 E2fsck -n will now always open the file system read-only. We now
2382 disallow certain combination of options which previously were manual
2383 exceptions; this is bad because it causes users to think they are
2384 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
2385 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
2387 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
2388 it detected a badly aligned partition. Unfortunately, this broke some
2389 distribution installation scripts, so it now just prints the warning
2390 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses

2402 e2fsck -fD can corrupt non-indexed directories when are exists one or
2403 more file names which alphabetically sort before ".". This can happen

2556 E2fsprogs 1.41.9 (August 22, 2009)
2557 ==================================
2559 Fix a bug in e2fsck routines for reallocating an inode table which
2560 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
2561 filesystem feature with a relatively rare (and specific) filesystem
2562 corruption. This fix causes e2fsck to try to find space for a new
2563 portion of the inode table in the containing flex_bg, and if that
2564 fails, the new portion of the inode table will be allocated in any
2565 free space available in the filesystem.
2567 Make e2fsck less annoying by only asking for permission to relocate a
2568 block group's inode table once, instead of for every overlapping
2569 block. Similarly, only ask once to recompute the block group
2570 checksums, instead of once for each corrupted block group's checksum.
2572 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
2573 not present, and it needs to fall back to using the FIBMAP ioctl.
2575 Fix filefrag to correctly print the number of extents for zero-length
2576 files. (Addresses Debian Bug: #540376)
2578 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
2579 to more easily debug the FIBMAP code.
2581 Fixed filefrag for non-extent based files.
2583 Add a new program, e2freefrag, which displays information about the
2584 free space fragmentation in an ext2/3/4 filesystem.
2586 Fix inode resizing via tune2fs -I so that it works correctly in the
2587 face of non-empty bad blocks inodes, and if the filesystem was
2588 formatted using the "mke2fs -E stride=N" option for RAID arrays.
2590 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
2591 and corrupt large directories if the directory needs to shrink by more
2592 than one block. (Addresses Debian Bug: #537510)
2594 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
2595 last mount times are in the future, they are corrected even if
2596 buggy_init_scripts is set. This is needed because otherwise resize2fs
2597 will refuse to resize the filesystem, even after running "e2fsck -f".
2598 (Addresses Launchpad bug: #373409)
2600 E2fsck will now print much fuller information when the last mount time
2601 or last written time is in the future, since most people can't seem to

2603 failed CMOS/RTS clock battery.

2628 there aren't any free blocks or inodes in the already-used block

2645 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
2646 setgid and the currently running program doesn't have write access to
2647 the uuidd work directory.
2649 Add safety checks (for non-Linux systems) so that uuidd isn't run with
2650 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
2651 will be careful not to close the file descriptor for its unix domain
2652 socket when it detaches itself from the controlling tty. Also add
2653 safety checks so that if the unix domain socket between the uuid
2654 library and uuidd program is closed for any reason, both the library
2655 and the uuidd will return an appropriate error code instead of looping
2656 in an infinite loop.
2658 The e2croncheck script, which creates an LVM snapshot and then checks
2659 the ext3/4 filesystem via the LVM snapshot, has been added to the
2662 Fix filefrag program for files that have more than 144 extents.

2693 E2fsprogs 1.41.7 (June 29, 2009)
2694 ================================
2696 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
2697 uninitalized data into the portion of the inode beyond the first 128
2698 bytes when operating on inodes mapped via extents; potentially
2699 corrupting filesystems.
2701 Fix memory leaks in e2fsprogs, including a very large memory leak
2702 which can cause e2fsck to run out of memory when checking very large
2703 filesystems using extents.
2705 The logsave program will now filter out the ^A and ^B characters when
2706 writing to the console.

2720 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
2721 filesystems as the kernel when encoding rec_len >= 64k. For 64k
2722 filesystems (currently all that is supported by e2fsprogs, this is
2723 only a minor corner case).
2725 Resize2fs will now update the journal backup fileds in the sup0erblock

2752 E2fsprogs 1.41.6 (May 30, 2009)
2753 ===============================
2755 Fix a critical regression in e2fsck introduced version 1.41.5 which
2756 can undo updates to the block group descriptors after a journal replay.
2758 If e2fsck receives an I/O error while replaying the journal, prompt
2759 the user whether they want to ignore the error or not; if e2fsck is
2760 run in preen mode, force fsck to abort the preen pass.
2762 Fix a bug which would cause e2fsck to core dump if the filesystem
2763 contains a corrupt extent header, and the user declines to clear the
2764 inode. (Addresses Sourceforge Bug: #2791794)
2766 Fix e2fsck to restart only once in the case of multiple block groups
2767 which inodes in use that are in the uninitialized part of the block
2768 group's inode table.
2770 To reduce user confusion, if the /etc/mtab file is missing
2771 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
2772 new, explicit error code to indicate this case. This will cause
2773 e2fsck to give a clearer error message when the user is using buggy
2774 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
2777 Fix e2fsck so that if the primary group descriptors are corrupted, but
2778 the backup superblock is entirely invalid, to go back to using (and
2779 fixing) the priary group descriptors instead of completely giving up
2780 on the filesystem. (Addresses Debian Bug: #516820)
2782 Change e2fsck to not abort a preen pass if an inode is found to have
2783 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
2784 kernels (post 2.6.29) will ignore this field. So let's fix it
2785 automatically during the preen pass instead of forcing the user to fix
2786 this up manually. (Addresses Debian Bug: #526524)
2788 Add resource tracking for e2fsck passes 1b through 1d.
2790 Speed up e2fsck by eliminating unnecessary journal checks if the
2791 filesystem is already mounted and doesn't need recovery (since the
2792 kernel would have run the journal when the filesystem was mounted.)
2793 Also speed up e2fsck by avoiding unnecessary block group descriptor
2794 updates in ext2fs_close().
2796 Add support to chattr to migrate inodes from using direct/indirect
2799 Avoid corrupting the filesystem if there is an attempt to shrink a
2800 filesystem using resize2fs smaller than posible by making
2801 ext2fs_set_bmap() more careful not to delete the old block until the
2802 new block can be inserted. In addition, fix a bug in how the minimum
2803 size of the filesystem (plus a safety margin) is calculated, and
2804 modify resize2fs to refuse to shrink the filesystem below that minimum
2805 size without the force flag.
2807 Teach blkid to try to figure out DM device names using take advantage
2808 of information in sysfs when running on kernels (2.6.29 and later)
2809 which provide this information in /sys/block/dm-<N>/dm/name; this is
2810 much faster than scanning for the devncie number in /dev/mapper.
2812 Fix blkid to prefer /dev/mapper/<name> device names instad of the
2813 private /dev/dm-X names.
2815 Add an -a option to debugfs's close_filesys command which writes any
2816 changes to the superblock or block group descriptors to all of the
2817 backup superblock locations.
2819 Add support to the filefrag program to use the FIEMAP ioctl.
2821 Update Chinese translation from the Translation Project.
2823 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
2824 Launchpad Bug: #381854)
2826 Fixed various Debian packaging issues --- see debian/changelog for
2827 details. (Addresses Debian Bug #506064)
2833 Add test code to make sure e2fsck's problem.c doesn't have two problem
2834 codes assigned to duplicate values.
2836 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
2837 (Addresses Sourceforge Bug: #2780205)
2839 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
2840 function declaration for init_resource_track() and
2841 print_resource_track() when RESOURCE_TRACK is not defined.
2843 The test code which is used to build the tst_csum progam has been
2844 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
2845 avoid compile problems caused by not having a prototype for
2846 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
2848 Update the config.guess and config.sub file to the latest from the
2849 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
2850 Debian Bug: #528330)
2852 Add a new function, ext2fs_extent_open2(), which behaves like
2853 pext2fs_extent_open(), but uses the user-supplied inode structure
2854 when opening an extent instead of reading the inode from disk.
2857 E2fsprogs 1.41.5 (April 23, 2009)
2858 =================================
2860 Fix a number of filesystem corruption bugs in resize2fs when growing
2861 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
2864 Debugfs can now set i_file_acl_high via the set_inodes_field command,
2865 and print a 64-bit file acl. This is useful for debugging filesystem
2866 corruptions where the high bits of i_file_acl_high are set. E2fsck
2867 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
2868 since some Linux kernel versions pay attention to this field even when
2871 Speed up e2fsck when checking clean filesystems by avoiding
2872 unnecessary block reads, and coalescing the block group descriptor
2873 blocks so they are read using a single read operation.
2875 The libuuid library will now close all file descriptors before running
2876 uuidd. This avoids problems when the calling program has open sockets
2877 which then never get closed because uuidd is a long-running helper
2878 daeomn. (Addresses Launchpad bug: #305057)
2880 In order to avoid unnecessary full filesystem checks by e2fsck after
2881 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
2882 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
2884 Mke2fs will avoid trying to create the journal when run in
2885 superblock-only mode (mke2fs -S), since the left-over journal in the
2886 inode table will cause mke2fs to fail.
2888 Fix a bug in libext2fs functions that check to see if a particular
2889 device or filesystem image is mounted, which would cause these
2890 functions to report that a file identical to the (relative) pathname
2891 used by a pseudo-filesystem was mounted when in fact it was not.
2893 Update Czech translation from the Translation Project.
2895 Add Chinese (simplified) translation from the Translation Project.
2897 Fix support for external journals (which was broken in e2fsprogs
2900 Fix a regression in debugfs where the "stat" command when no
2901 filesystem was open would cause debugfs to crash with a segmentation
2904 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
2905 used to support filesystems without a journal. Update the blkid
2906 library so it understands this.
2908 The blkid library will remove an entry from the blkid cache
2909 representing the entire disk if partitions are found, since presuambly
2910 the device previously had no partition table, but has now transitioned
2911 to using a partition table.
2913 Add a check to mke2fs and tune2fs that the argument to the -m option
2914 (which specifies the reserved ratio) must be greater than zero.
2915 (Addresses Debian Bug: #517015)
2917 Add support for tracking the number kilobytes written to the
2918 filesystem via the superblock field s_kbytes_written. It will be
2919 updated by the kernel as well as by e2fsprogs programs which write to
2920 the filesystem. This is useful for tracking the wear to filesystems

2948 ===================================
2950 Fixed a bug which could sometimes cause blkid to return an exit value
2951 of zero for a non-existent device (Addresses Debian Bug: #502541)
2953 Blkid will now recognize ext3 filesystems that have the test_fs flag
2954 set as ext3 filesystems.
2956 The blkid library will now recognize btrfs filesystems and swap
2957 devices currently used by user-level software suspend.
2959 Tune2fs now updates the block group checksums when changing the UUID
2960 to avoid causing e2fsck to complain vociferously at the next reboot.
2962 Tune2fs's inode size resizing algorithms have been fixed so it is not
2963 vastly inefficient for moderate-to-large filesystems, due to some
2964 O(n**2) and O(n*m) algorithms that didn't scale well at all.
2966 Fix tune2fs's inode resizing algorithm so it will not corrupt
2967 filesystems laid out for RAID filesystems; in addition, tune2fs will
2968 refuse to change the inode size for filesystems that have the flex_bg
2969 feature enabled. (This is a limitation in the current implementation
2972 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
2973 filesystems with 32-bit block numbers, when the headers for 64-bit
2974 block numbers was added. This regression has been fixed.
2976 Debugfs's ncheck command has been fixed to avoid printing garbage
2977 characters at the end of file names.
2979 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
2980 when shrinking filesystems with uninit_bg feature would not be moved.
2981 In addition, blocks and inode table blocks were not being correctly
2982 freed when shrinking filesystems with the flex_bg feable, which caused
2983 resize2fs -M to fail. Finally, when blocks are moved, make sure the
2984 uninitialized flag in extents is preserved.
2986 Fix bug which caused dumpe2fs to abort with an error if run on a
2987 filesystem that contained an external journal.
2989 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
2990 for this in argv[0] to provide better legacy support for these
2991 distributions. This is a practice that should NOT be continued,
2994 Mke2fs now has a new option -U, which allows the user to specify the
2995 UUID that should be used for the new filesystem.
2997 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
2998 minus one block. This allows users who have read that ext3 supports
2999 up to 16TB filesystems and who create a 16TB LVM to not get confused,
3000 since the true limit is really 16TB minus one block.
3002 E2fsck will no longer abort an fsck run if block group has an errant
3005 E2fsck now distinguishes between fragmented directories and fragmented
3006 files in verbose mode statistics and in the fragcheck report.
3008 Fix a bug in e2fsck which casued it double count non-contiguous
3009 extent-based inodes.
3011 E2fsck will leave some slack space when repacking directories to allow
3012 room for a few directory entries to be added without causing leaf
3013 nodes to be split right away.

3016 corrupted interior node in an extent tree with the error message:

3034 Fix build of e2fsck.profiled, and add support for building profiled
3035 binaries in the misc directory if configured with --enable-profile.
3037 The ext2fs_open() function now performs more sanity checks on the
3038 superblock to avoid potential divide by zero errors by other parts of
3041 The ext2fs_read_inode_full() function now has a safety check to avoid
3042 a segmentation fault on corrupted filesystems.
3044 The ext2fs_new_inode() function now has a sanity check so that if the
3045 s_first_inode field in the superblock is insane, it will return
3046 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
3048 To avoid segmentation faults, ext2fs_block_alloc_stats() and
3049 ext2fs_inode_alloc_stats() now validates the passed inode or block
3050 number to avoid overrunning an array boundary.
3052 Various signed/unsigned errors for variables containing block numbers
3055 Accomodations for gcc's stupidity in not realizing that constant
3056 strings that do not contain a '%' character are safe to use in format
3057 strings have been made so that distributions that want to compile
3058 e2fsprogs with -Werror=format-security have an easier time doing so.
3060 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
3062 Added the utility make-sparse.c to the contrib directory.
3064 The ext2fs_block_iterate2() function now reflects errors from
3065 ext2fs_extent_set_bmap() to the caller, if the callback tries to
3066 change a block on an extent-based file, and ext2fs_extent_set_bmap()
3067 fails for some reason (for example, there isn't enough disk space to
3068 split a node and expand the extent tree.
3070 The ext2fs_block_iterate2() function will preserve the uninit flag in
3071 extents when the callback function modifies a block in an extent-based
3074 E2fsck will now flag filesystems that have an insane s_first_ino field
3075 in their superblock, and attempt to use a backup superblock to repair
3079 E2fsprogs 1.41.3 (October 12, 2008)
3080 ===================================
3082 E2fsck has been fixed so it prints the correct inode number for
3083 uinit_bg related problems.
3085 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
3086 is available on linux. This can be disabled via a configuration
3087 option in /etc/e2fsck.conf.
3089 Fix a file descriptor leak in libblkid when checking to see if an ext4
3090 or ext4dev module exists.
3092 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
3093 while trying to close a filesystem can lead to infinite loops.
3094 (Addresses Red Hat Bugzilla #465679)
3096 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
3097 will cause resize2fs to drop into an infinite loop. (Addresses Red
3098 Hat Bugzilla: #465984)
3100 Add a check in the Unix I/O functions in libext2fs so that when a
3101 device is opened read/write, return an error if the device is
3102 read-only using the BLKROGET ioctl.
3104 Fix debugfs's ncheck command so that it prints all of the names of
3105 hardlinks in the same directory.
3107 Fix a bug in libblkid so it correctly detects whether the ext4 and
3108 ext4dev filesystems are available, so that the ext4dev->ext4
3109 fallback code works correctly.
3114 Fix a parallel build problem by making sure util/subst is built before
3115 trying to build the lib/et directory. (Addresses Sourceforge Bug:
3118 Updated "make depend" information for crc16.o
3121 E2fsprogs 1.41.2 (October 2, 2008)
3122 ==================================
3124 Fix e2fsck's automatic blocksize detection. This fixes a regression
3125 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
3126 specifies a block number using the -b option if the blocksize option
3127 isn't also specified using -B. Unfortunately, users very commonly
3128 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
3129 superblock; in fack e2fsck will often suggest this kind of command
3132 Enhance the debugfs's "ncheck" command so it will print all of the
3133 pathnames for the specified inodes. (Previously, in some cases ncheck
3134 might not print a pathname for an inode at all if some of the other
3135 inodes had multiple hard links.)
3137 Enhance debugfs's "hash" command so the hash seed can be specified via
3138 a command-line option. In addition, allow the hash algorithm to be
3139 specified by name instead of just by number.
3141 Fix e2fsck so that we don't accidentally print the translation file's
3142 header when asking the user a custom question so there is no prompt
3143 defined for a particular problem record. For example, the question
3144 "Run journal anyway" will get the PO header tacked on because e2fsck
3145 erroneously passed the null string to _(). (Addresses Launchpad Bug:
3148 Enhance badblocks so that it can test a normal file which is greater
3151 Enhance the badblocks command so that it displays the time and
3152 percentage complete when in verbose mode. (Addresses Debian Bug:
3155 Fix a potential memory leak in a error handling path in debugfs's
3158 Fix a potential memory corruption problem if a memory allocation fails
3161 Fix the usage message for debugfs's logdump command to be consistent
3162 with its man manpage.
3164 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
3165 and Sweedish translation from the Translation Project.
3167 Add documentation for the file I/O functions to the libext2fs.texinfo
3168 file. (Addresses Debian Bug: #484877)
3170 Update and clarified various man pages. (Addresses Launchpad Bug
3171 #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
3173 Fixed various Debian packaging issues --- see debian/changelog for
3174 details. (Addresses Debian Bug: #497619)
3179 Fix a potential file descriptor leack in libcom_err by setting the
3180 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
3183 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
3184 has been carrying a patch for a long time to prevent a largely
3185 theoretical race condition if a multi-threaded application adds and
3186 removes error tables in multiple threads. Unfortunately SuSE's
3187 approach breaks compatibility by forcing applications to link and
3188 compile with the -pthread option; using pthread mutexes has
3189 historically been problematic. We fix this by using sem_post/sem_init
3192 Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
3193 Sourceforge Bug: #2087502)
3195 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
3196 libraries when using ELF shared libraries.
3198 Fix ELF shared library when building on systems that don't already
3199 have the e2fsprogs shared libraries already installed. (Addresses
3200 Sourceforge Bug: #2088537)
3202 Fix the pkg-config files so they work correctly when linking with
3203 static libraries and fix the include directory so programs don't have
3204 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
3205 instead. (Addresses Sourceforge Bug: #2089537)
3207 Make sure ext2fs_swab64() is compiled for all platforms, and not just
3208 for x86. (Addresses Debian Bug: #497515)
3210 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
3211 non-x86 platforms. (They had been removed for x86 earlier.)
3213 Fix diet libc compilation support, which had bitrotted due to lack of
3214 TLC. Fixing this improves general portability.
3216 When installing the link library when using ELF shared libraries,
3217 avoid using absolute pathnames if the link library and the shared
3218 library are installed in the same directory. (Addresses Sourceforge
3221 Fix gen-tarball so it will work even if the top-level directory has
3222 been renamed to something other than "e2fsprogs". Also make
3223 gen-tarball print the size of the resulting tar.gz file.
3226 E2fsprogs 1.41.1 (September 1, 2008)
3227 ====================================
3229 Many people are forgetting to update their mke2fs.conf file, and this
3230 causes ext3, ext4, and ext4dev filesystems won't get created with the
3231 proper features enabled. We address this in two ways. First, mke2fs
3232 will issue a warning if there is not definition for an ext3, ext4, or
3233 ext4dev filesystem and the user is trying to create such a filesystem
3234 type. Secondly, when installing from a source build, "make install"
3235 will provide basic configuration file handling for /etc/mke2fs.conf.
3236 If it exists, and does not mention ext4dev, it will be moved aside to
3237 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
3238 be installed. If the existing /etc/mke2fs.conf file does mention
3239 ext4dev, then "make install" will install official mke2fs.conf file as
3240 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
3241 they should look to see if any changes need to be merged.
3243 The mke2fs program will now create the journal in the middle of the
3244 filesystem, since this minimizes seek times on average for fsync-heavy
3245 workloads. In addition, mke2fs will now create journals using extents
3246 for filesystems that support them. This results in a more efficient
3247 encoding for the journal since it eliminates the need for using
3250 The mke2fs program will avoid allocating an extra block to the
3251 journal. (Addresses Sourceforge Bug: #1483791)
3253 Mke2fs will correctly enforce the prohibition against features
3254 (specifically read-only features) in revision 0 filesystems. (Thanks
3255 to Benno Schulenberg for noticing this problem.)
3257 Mke2fs previously would occasionaly create some slightly non-optimally
3258 placed inode tables; this bug has been fixed.
3260 The mke2fs and tune2fs programs now print the correct usage message
3261 describing the maximum journal size. (Addresses Debian Bug: #491620)
3263 Add support for setting the default hash algorithm used in b-tree
3264 directories in tune2fs (from a command-line option) or mke2fs (via
3265 mke2fs.conf). In addition, change the default hash algorithm to
3266 half_md4, since it is faster and better.
3268 The blkid library will now recognize MacOS hfsx filesystems, and
3269 correctly extract the label and uuid for hfs, hfsx, and hfsplus
3270 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
3272 The blkid library has improved detection of JFS and HPFS filesystems.
3273 (Addresses Launchpad Bug: #255255)
3275 The blkid library is now much more efficiently handling devicemapper
3276 devices, mainly by no longer using the devicemapper library. This can
3277 speed up access for systems with a large number of device mapper
3280 Blkid had a number of cache validation bugs in libblkid that have been
3281 fixed. (Addresses Debian Bug: #493216)
3283 Resize2fs will now properly close out the "updating inode references"
3284 progress bar so there is a newline printed before printing the final
3285 "resize is successful" message.
3287 Resize2fs will now correctly handle filesystems with extents and/o
3288 uninitialized block groups correctly when file/directory blocks need
3289 to relocated (i.e., when shrinking a filesystem or if the resize_inode
3290 is not present). To support this, the ext2fs library now supports
3291 initializing inode and block bitmaps that are not yet initialized when
3292 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
3293 addition, e2fs_block_iterate2() can now support changing the location
3294 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
3295 been optimized to avoid creating unnecessary new extents when updating
3296 the location of blocks in the extent tree. This will also help out
3297 e2fsck's recovery of obscurely corrupted filesystems with extents,
3298 when blocks are claimed by multiple inodes.
3300 Add support for on-line resizing ext4 filesystem with the flex_bg
3301 filesystem feature. The method for doing so is not optimal, but to do
3302 a better job will require kernel support.
3304 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
3305 debugfs programs to not be able to read e2image files; the signed
3306 vs. unsigned bug in the code which read bitmaps from the e2image has
3307 been fixed. (Addresses Debian Bug: #495830)
3309 Resize2fs is now correctly managing the directory in-use counts when
3310 shrinking filesystems and directory inodes needed to be moved from one
3311 block group to another. This bug has been around since e2fsprogs
3312 1.26, and is largely harmless, but does cause a filesystem corruption
3313 which will be flagged by e2fsck after the filesystem has been shrunk.
3315 E2fsck will no longer issue spurious complaints about the inode size
3316 caused by very large extent-based files, and by blocks reallocated
3317 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
3318 Kernel Bugzilla: #11341)
3320 Mke2fs will now set the creation timestamp on the lost+found directory
3321 and the root directory. (More generally, all new inodes created using
3322 the ext2fs library will correctly set the creation timestamp.)
3324 E2fsck now correctly calculates ind/dind/tind statistics in the
3325 presence of extent-based files. In addition, "e2fsck -v" will report
3326 statistics of the depth of extent trees in the filesystem. E2fsck can
3327 also give an inode fragmentation report using "e2fsck -E fragcheck"
3328 which can be useful when debugging the kernel block allocation
3331 Fix support for empty directory blocks in ext4 filesystems with 64k
3332 blocksize filesystems.
3334 E2fsck will now print the depth of corrupt htree directories.
3336 Debugfs's htree command now correctly understands extent-based
3337 directories. It will also print out the minor hash as well as the
3340 Debugfs has a new command which will print the supported features of
3341 e2fsprogs, to enable scripts to know whether the installed version of
3342 e2fsprogs can support a specific feature.
3344 Debugfs will now write files using extents for filesystems that
3347 The error message printed by "tune2fs -I" if the inode size was too
3348 small was rather confusing, so it has been improved. Also, we won't
3349 try to create an undo log until we know that command-line-specified
3350 parameters such as "tune2fs -I <inode size>" are valid.
3352 Given some filesystems found "in the wild" that had non-zero block
3353 group checksums even though the uninit_bg/gdt_sum feature was not
3354 enabled, e2fsck would issue spurious error messages. Teach
3355 ext2fs_group_desc_csum_verify() to ignore the block group checksum
3356 entirely if the feature flag is not set. (Addresses Debian Bug:
3359 The blkid program will now print out a user-friendly listing of all of
3360 the block devices in the system and what they contain when given the
3361 -L option. (Addresses Debian Bug: #490527)
3363 The filefrag program now has a more accurate calculation for the
3364 number of ideal extents. (Addresses Debian Bug: #458306)
3366 The test I/O manager is now enabled by default, but its overhead is
3367 only incurred when it would be enabled via the TEST_IO_FLAGS or
3368 TEST_IO_BLOCK environment variables.
3370 Typographical errors in various program strings and usage messages
3371 have been fixed; most of these were pointed out by the e2fsprogs
3372 message catalog translators. (Thanks, translators!)
3374 Update and clarified various man pages, as well as some typographical
3375 errors in the libext2fs texinfo file.

3387 Fix portability problem with the badblocks group; for systems that
3388 don't have nanosleep(), try using usleep() instead.
3390 The "make check" target in the e2fsck directory now sets
3391 LD_LIBRARY_PATH before running the various e2fsck internal library
3394 The crc32 regression test in the e2fsck library is now portable to
3395 greater varienty of environments, including big-endian systems and
3396 when cross-building e2fsprogs for embedded systems. (Addresses
3397 Sourceforge Bug: #2019287)
3399 The ext2fs_extent_set_bmap() had some bugs when setting the first
3400 block in a file, or when replacing a single block extent. Those cases
3401 fortunately were came up relatively rarely when e2fsck was checking
3402 files, but caused some problems when resize2fs was shrinking
3405 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
3408 Various ext2fs library functions --- ext2fs_block_iterate2(),
3409 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
3410 allocated memory to avoid memory leaks in all of their error return
3413 Ext2ed was failing to build because masix support had been removed in
3414 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
3416 The configure script now respects the LDFLAGS environment variable if
3417 it is set when configure is called. (Addresses Sourceforge Feature
3420 Libuuid is now more portable to the Windows platform. (Addresses
3421 Sourceforge Feature Request: #1937287)
3423 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
3424 bare echo commands so that configure flags such as --quiet work
3425 correctly. (Addresses Sourceforge Patches: #2058794)
3427 A few uses of sprintf have been removed from the ext2fs library to
3428 make life easier for bootloaders with a limited libc environment.
3429 (Addresses Sourceforge Bug: #2049120)
3431 The ext2fs_read_inode() checks the validity of the inode number passed
3432 to it earlier, to avoid doing some needless work when it would fail
3435 The ext2fs_open() checks the validity of the blocksize parameter
3436 passed to it earlier, to avoid doing some needless work when it would
3439 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
3440 top-level Makefile. That automatic rule is used to better support
3441 SCCS, but it caused problems for a particular niche distribution which
3442 likes to use configure.sh files to store the configure options used to
3443 build a package. Unfortuntaely GNU make will use the configure.sh to
3444 replace the configure script, resulting in a self-inflicted fork bomb
3445 leading to an out-of-memory crash.
3447 To support old GNU C compilers don't use C99/C++ comments, but only
3448 K&R style comments, and don't try to use __builtin_expect if __GNUC__
3449 is less than 3. (__builtin_expect is only supported for gcc versions
3450 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
3451 this is an optimization, we only try to use __builtin_expect for gcc 3
3454 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
3455 __LITTLE_ENDIAN, which are only defined by glibc's header files and
3456 hence isn't portable.
3458 For the convenience for some distributions that need a static tune2fs,
3459 the Makefile for misc/ now has a tune2fs.static target.
3461 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
3462 for extent-based files
3464 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
3467 All source files no longer have any trailing white space.
3469 The io_channel_read_blk64() and io_channel_write_blk64() functions are
3470 now functions instead of C preprocessor macros to provide better
3471 forward compatibility.

3478 Fix a parallel build problem in e2fsprogs.
3480 E2fsprogs is now more portable to Solaris.
3481 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
3483 * Scripts do not assume that /bin/true is always in /bin
3484 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
3485 * Flush stdio handles before calling setbuf(), since Solaris will
3486 discard any pending output to the stream.
3487 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
3488 picky about which C compiler can beused for SUSv3 conformance.
3489 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
3490 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
3491 Since we need some SUSv3 functions, consistently use SUSv3 so
3492 that e2fsprogs will build on Solaris using c99.
3493 * Solaris C99 does not support varargs C preprocessor macros
3494 * Solaris header files pollute the C namespace if in/netinet.h
3495 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
3497 * Solaris ships with a pathetically ancient shell in /bin/sh so we
3498 avoid the use of various more avanced shell constructs such as $().
3500 The "make rpm" command will now take some extra configure optiosn from
3501 the build environment without needing to patch the source tree.
3503 The ext2fs_add_dir_block() function will now grow the dblist more
3504 aggressively as an optimization to avoid copying the array too often.
3506 The e2fsck_write_bitmaps() will write the block and inode bitmaps
3507 together instead of in two passes.
3510 E2fsprogs 1.41 (July 10, 2008)
3511 ==============================
3513 Add support for ext4 filesystem features, in particular extents,
3514 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
3515 support for checking journal checksums. Debugfs will print new
3516 superblock and inode fields that were defined for ext4. For example,
3517 the nanosecond and i_version fields of an inode, and the
3518 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
3519 Note: Resize2fs doesn't currently support the combination of flex_bg
3520 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
3522 Tune2fs can support migrating a filesystem from using 128 byte inodes
3523 to 256 byte inodes, so it can take advantage of the full features of
3526 Add support for "undo" support. E2fsck and mke2fs can optionally
3527 record an undo log which can replayed by the program e2undo.
3529 E2fsck could damage a filesystem by trying to relocate inode tables
3530 due to corrupted block group descriptors, where the attempted inode
3531 table relocation would do far more harm than good. E2fsck has been
3532 fixed to detect this these sorts of corrupted block group descriptors
3533 much earlier in e2fsck processing, so it can try to use the backup
3534 superblock and block group descriptors first. This should be a much
3535 better strategy for recovering these types of corrupted filesystems.
3536 (Addresses Sourceforge Bug: #1840291)
3538 E2fsck will display a more understandable message when the last check
3539 field in the superblock is in the future. (Addresses Debian Bug:
3542 E2fsck now performs more extensive and careful checks of extended
3543 attributes stored in the inode.
3545 Enhance mke2fs to print a more explanatory error message when
3546 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
3549 Fix mke2fs to use a default block size of 4k when formatting an
3550 external journal device. This is done by using a fixed filesystem
3551 type list that consists only of the single filesystem type "journal"
3552 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
3553 Debian Bug: #488663)
3555 Speed up how mke2fs writes the journal data blocks by writing the disk
3556 blocks in larger chunks.
3558 Fix blkid handling of stale devices. Fix a bug which could cause a
3559 core dump while garbage collecting the blkid cache, and assure that
3560 blkid_find_dev_with_tag() never returns a non-existent device. Also,
3561 if a filesystem is found at a new /dev location, eliminate any
3562 duplicate stale entries which can not be verified.
3563 (Addresses Debian Bugs: #487758, #487783)
3565 Add more paranoid checks for LVM volumes and swap partitions in
3566 blkid's probe function, to reduce the chances of false positives.
3568 The mke2fs program now has a much more sophisticated system for
3569 controlling configuration parameters of a newly created filesystem
3570 based on a split filesystem and usage type system. The -t option to
3571 mke2fs was a deprecated alias to -c; it now specifies a filesystem
3572 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
3573 separated usage list. The filesystem type information and type
3574 information is used to extract configuration parameters from the
3575 /etc/mke2fs.conf file.
3577 The mke2fs program will no longer complain and request the -f option
3578 when the user tries to create a filesystem with greater than 2**31
3581 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
3582 adjust the mke2fs.conf file so filesystems for the Hurd are created
3583 with a blocksize of 4096 and inode size of 128, which is all it knows
3584 how to handle. (Addresses Debian Bug: #471977)
3586 Mke2fs will always make sure that lost+found always has at least 2
3587 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
3589 Resize2fs will now print the minimum needed filesystem size if given
3590 the -P option, and will resize the filesystem to the smallest possible
3591 size if given the -M option.
3593 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
3594 blocks are consumed during an off-line resize.
3596 The "ls" command in debugfs now supports the -p option, which causes
3597 it to quote the filenames so that spaces or tabs in directory entries
3598 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
3599 Sourceforge Feature Request: #1201667)
3601 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
3604 The chattr program will return a non-zero exit code in case of
3605 failures, and error messages can be suppressed with the -f option.
3606 (Addresses Red Hat Bugzilla: #180596)
3608 Fix a bug in badblocks which caused it to overrun an array and likely
3609 crash if more than 8 test patterns are specified using the -t option.
3610 (Addresses Debian Bug: #487298)
3612 Add support to badblocks to limit how quickly it reads from the disk
3613 drive (so it can be used for background scrubbing), and so it will
3614 abort after finding a given number of errors.
3616 Remove support for the legacy big-endian filesystem format which only
3617 existed on extremely long-dead PowerPC kernels almost a decade ago.
3619 Remove MASIX support from e2fsprogs.
3621 Add I/O statistics reporting to e2fsck.
3623 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,

3650 Avoid using predictable filenames in /tmp in blkid's regression test
3651 suite. Also remove bashism's in the regression test script.
3653 If the configure script is given --with-diet-libc, don't use thread
3654 local storage, since diet libc doesn't support TLS. (Addresses
3655 Sourceforge Bug: #2000654)
3657 Fix the blkid regression test suite to tolerate older versions of
3658 mkswap that don't support the -U option.
3660 A few library routines have been converted to support 64-bit block
3661 numbers; in particular, the I/O manager functions, the test_io,
3662 inode_io, and unix_io managers have all be converted to support 64-bit
3665 Debugfs can now be extended for use by test programs. See
3666 lib/ext2fs/extents.c for an example for how it can be used. The test
3667 program links against the debugfs object files, and provides
3668 additional commands by defining an auxiliary libss command table.
3670 The lazy_bg filesystem feature, which was only used by developer's
3671 testing, has been removed since it has been largely supplanted by
3672 uninit_bg. This also simplifies the code.
3675 E2fsprogs 1.40.11 (June 17, 2008)
3676 =================================
3678 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
3679 percentage of reserved blocks. (Addresses Debian Bug: #452639)
3681 Updated Spanish and Catalan translations.

3694 Fix marginal C code in probe_lvm2() function to the blkid library more
3695 portable for older compilers.

3699 Fix ext2fs_swap{16,32,64} functions so they can be used by external
3700 applications on big-endian machines. (Addresses Debian Bug: #484879)
3703 E2fsprogs 1.40.10 (May 21, 2008)
3704 ================================
3706 When deciding whether or not to revalidate a blkid cache entry, if the
3707 device's mtime is newer than the last time the cached entry was
3708 validated, force a revalidation.
3710 Fix a potential data corruption bug in e2fsck in the journal replay.
3711 The chances of this is happening is extremely remote, especially the
3712 default data=ordered or data=writeback modes. However, if a block
3713 which has been journalled starts with the first four bytes 0xc03b3998,
3714 when e2fsck replays the journal, those four bytes will be replaced
3715 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
3716 metadata to begin with those fatal 4 byte sequence, and unless
3717 data=ordered mode is in use, data blocks are never journaled.
3719 Updated German, Dutch, Sweedish, and Vietnamese translations.
3724 Fixed various Debian packaging issues --- see debian/changelog for
3727 Remove default sizes of types when cross compiling, since autoconf
3728 2.50 can figure this out automatically now.
3731 E2fsprogs 1.40.9 (April 27, 2008)
3732 =================================
3734 SuSE's security team audited uuidd and came up with a few minor
3735 issues. None of them are serious given that uuidd runs setuid as a
3736 unprivileged user which has no special access other than libuuid
3737 directory, but it's good to get them fixed.
3739 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
3740 work correctly with in-inode extended attributes.
3742 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
3745 Debugfs will avoid using a pager if the standard output is not a tty.
3747 Fix debugfs and tune2fs to correctly handle daylight savings time when
3748 parsing a time string.
3750 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3752 Fix fsck completion bars when multiple filesystems were being checked
3753 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
3754 #203323, Addresses Sourceforge Bug: #1926023)
3756 Fix fsck so that progress information is sent back correctly when
3757 multiple filesystems are being check and the output of fsck is being
3758 redirected to a file descriptor. Also, include the device name (w/o
3759 spaces) in the progress information sent back via a file descriptor.
3760 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
3763 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
3765 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
3766 signal to its child process.
3768 Fix mke2fs's creation of are resize inode when there is a non-standard
3769 s_first_data_block setting.
3771 Fix bug in blkid when run by an unprivileged user; most devices were
3772 not reported correctly. 9Addresses Launchpad Bug: #220275)
3774 Mke2fs will not allow the logically incorect combination of
3775 resize_inode and meta_bg, which had previously caused mke2fs to create
3776 a corrupt fileystem.
3778 Fix fsck in German locales so that a 'j' means yes.

3785 Fixed various Debian packaging issues --- see debian/changelog for
3788 Update valgrind options in test_script to work with valgrind 3.2.3

3797 Fix build system so that if texinfo is not installed, it won't print a
3798 (harmless) error message.
3801 E2fsprogs 1.40.8 (March 13, 2008)
3802 =================================
3804 Fixed e2image -I so it works on image files which are larger than 2GB.
3806 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
3807 the size is larger than the number of blocks found in the inode, don't
3808 try to allocate extra empty blocks at the end of the directory to make
3809 up the difference; there's no point to doing that. In addition, if
3810 the size is not a multiple of a blocksize, always fix it.
3812 E2fsck handled a pass 2 "should never happen error" by not giving
3813 enough information and then core dumping. Unfortunately, it was all
3814 too easy to trigger the "should never happen" situation if a
3815 directory's inode size was not correct. This has been fixed, but
3816 e2fsck has also been taught how to handle this situation more
3817 gracefully, by simply removing the inode hash tree information, so
3818 that it can be rebuilt again after e2fsck's pass 3. (Addresses
3819 Launchpad Bug: #129395)
3821 Resize2fs had a bug resizing large inodes with extended attributes
3822 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
3823 completely on big-endian systems such as PowerPC. The bug should be
3824 completely fixed now. Yay for regression test suites. (Addresses Red
3825 Hat Bugzilla: #434893)
3827 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
3828 translations. Many thanks to Philipp Thomas from Novell for stepping
3829 up to become the new German translation maintainer! (Addresses Debian
3830 Bugs: #302512, #370247, #401092, #412882).
3832 When e2fsck is clearing a corrupt inode's HTREE directory information,
3833 make it clear that it is just clearing the HTREE information, not the
3836 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3841 Add new functions, ext2fs_dblist_get_last() and
3842 ext2fs_dblist_drop_last(), which allows the caller to examine the last
3843 directory block entry added to the list, and to drop if it necessary.
3845 Fixed a portability problem in libblkid with DJGPP.
3847 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
3848 to Philipp Thomas for pointing this out.
3850 If the info files are not built, change "make install" so it doesn't
3851 fail with an error code.
3854 E2fsprogs 1.40.7 (February 28, 2008)
3855 ====================================
3857 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
3858 depreciate the -s option, since it can result in filesystems which
3859 e2fsck can't fix easily. There are very good reasons for wanting to
3860 disable sparse_super; users who wants to turn off sparse_super can use
3861 debugfs. (Addresses Sourceforge Bug: #1840286)
3863 Add missing options to mke2fs's usage message. (Addresses Sourceforge
3866 Fix bug in resize2fs when large (greater than 128 byte) inodes are
3867 moved when a filesystem is shrunk; it was only moving the first 128
3868 bytes, so extended attributes were not getting moved. (Addresses Red
3869 Hat Bugzilla: #434893)
3871 E2fsck now prints an explicit message when the bad block inode is
3872 updated, to avoid confusion about why the filesystem was modified.
3873 (Addresses Sourceforge Bug: #756460)
3875 Allow mke2fs and tune2fs manipulate the large_file feature.
3876 Previously we just let the kernel and e2fsck do this automatically,
3877 but e2fsck will no longer automatically clear the large_file feature.
3878 It still isn't really necessary to worry about this feature flag
3879 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
3882 Suppress message about an old-style fstab if the fstab file is empty.
3883 (Addresses Debian Bug: #468176)
3885 Fix (really minor) bug in debugfs's find_free_block so it avoids
3886 reporting a free block more than once if there are too few free blocks
3887 in the filesystem. (Addresses Sourceforge Bug: #1096315)
3889 Change e2fsck to no longer clear the LARGE_FILES feature flag
3890 automatically, when there are no more > 2GB files in the filesystem.
3891 It's been almost a decade since there have been kernels that don't
3892 support this flag, and e2fsck clears it quietly without telling the
3893 user why the filesystem has been changed.
3895 Fix bug which could cause libblkid to seg fault if a device mapper
3896 volume disappears while it is being probed. (Addresses RedHat
3899 Inhance e2fsck's reporting of unsupported filesystem feature flags.
3900 (Addresses Sourceforge Feature Request: #1175808)
3902 Fix option syntax in dumpe2fs for explicit superblock and blocksize
3903 parameters. What was currently documented in the man page has been
3904 broken for some time, due to getopt() implementation changes. The
3905 option sytax has been changed to one which is can be more portable
3906 supported and which is consistent with the format for extended options
3907 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
3909 Add support to tune2fs to clear the resize_inode feature. This
3910 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
3912 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
3915 Add support for setting RAID stride and stripe-width via mke2fs and

3944 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
3945 partially filled-in filesystem object on an error, so that e2fsck can
3946 print more intelligent error messages.
3948 Add a new function e2p_edit_feature2() which allows the caller to
3949 specify which feature flags are OK to set or clear, and which returns
3950 more specific information about feature flags which are not allowed to
3953 Set the C locale in the test_script driver since it uses [A-Za-z].

3977 ===================================
3979 Add support for returning labels for UDF filesystems in the blkid
3982 Fix bug in the blkid library where cached filesystems was not being
3983 flushed when opening USB devices returned the error ENOMEDIUM.
3984 (Addresses Debian Bug: #463787)
3986 Added logic to the blkid library to automatically choose whether a
3987 filesystem should be mounted as ext4 or ext4dev, as appropriate.
3989 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
3991 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
3992 configured with --enable-jbd-debug.

4014 ===================================
4016 Fix a potential overflow big in e2image if the device name is too
4019 Mke2fs will now create new filesystems with 256 byte inodes and the
4020 ext_attr feature flag by default. This allows for much better future
4021 compatibity with ext4 and speeds up extended attributes even on ext3
4024 Teach e2fsck to ignore certain "safe" filesystem features which are
4025 set automatically by the kernel. Having the kernel set features
4026 automagically behind the user's back is a bad idea, and we should try
4027 to break the kernel of this habit, especially for the newer ext4
4028 feature flags. But for now, we will try to avoid needless full checks
4029 which can annoy users who are doing fresh installs.
4031 Add support in tune2fs and mke2fs for making a filesystem as being "ok
4032 to be used with test kernel code". This will be needed for using test
4033 filesystems with the latest ext4 kernel code.
4035 Change e2fsck -fD so that it sorts non-htree directories by inode
4036 numbers instead of by name, since that optimizes performances much
4037 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
4039 If e2image fills the disk, fix it so it exits right away instead of
4040 spewing large numbers of error messages.
4041 (Addresses-Sourceforge-Feature-Request: #606508)
4043 If ftruncate64() is not available for resize2fs, let it use ftrucate()
4044 instead, but have it check to see if the size would get truncated, and
4045 skip calling ftruncate in that case.
4047 Add support for detecting HFS+ filesystems in the blkid library.
4049 Add supprt in the blkid library for ext4/ext4dev filesystems.
4051 Fix a bug in blkid where it could die on a floating point exception
4052 when presented with a corrupt reiserfs image.
4054 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
4055 such that UUID string is a fixed length.
4057 Add sample python bindings for the uuid library to the contrib
4058 directory. (Addresses-Sourceforge-Patches: #778817)

4160 Fix a potential security vulnerability where an untrusted filesystem
4161 can be corrupted in such a way that a program using libext2fs will

4164 exploits exist, but main concern is where an untrusted user who
4165 possesses privileged access in a guest Xen environment could corrupt a

4168 gain privileged access in the host OS. Thanks to the McAfee AVERT
4169 Research group for reporting this issue. (Addresses CVE-2007-5497.)
4171 Fix hueristics in blkid which could cause a disk without partitions to
4172 be incorrectly skipped when a loopback device is present. (Addresses
4173 Red Hat Bugzilla #400321.)
4175 Fix e2image so that in raw mode it does not create an image file which
4176 is one byte too large.
4178 Change mke2fs's usage message so it recommends the preferred -E option
4179 instead of the deprecated -R option.
4181 Enhance the blkid library so it will recognize squashfs filesystems.
4182 (Addresses Red Hat Bugzilla #305151.)
4184 Enhance e2fsck so it will force the backup superblocks to be backed up
4185 if the filesystem is consistent and key constants have been changed
4186 (i.e., by an on-line resize) or by e2fsck in the course of its
4189 Enhance blkid's detection of FAT filesystems; so that USB disks with
4190 only a single bootable partition will not get missed.
4192 E2fsck will no longer mark a filesystem as invalid if it has time
4193 errors (i.e., if superblock mount time or last write time is in the
4194 future) and the user refuses to fix the problem.
4196 The Ubuntu init scripts don't properly set the system time correctly
4197 from hardware clock if the hardware clock is configured to tick local
4198 time instead of GMT time. Work around this as best as we can by
4199 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
4200 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
4203 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
4204 Hat Bugzilla #151533.)
4206 Fix e2fsck so that if the superblock is corrupt, but still looks
4207 vaguely like an ext2/3/4 superblock, that it automatically tries to
4208 fall back to the backup superblock, instead of failing with a hard
4211 Make the e2fsprogs program more robust so that they will not crash
4212 when opening a corrupt filesystem where s_inode_size is zero.
4214 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
4215 arguments are detected as such and the parse error is reported to the
4216 user. (Addresses Debian Bug #435381.)
4218 Change e2fsck so it will not complain if a file has blocks reallocated
4219 up to the next multiple of a system's page size.
4221 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
4222 about (valid) filesystems where the inode table extends to the last
4223 block of the block group. (Addresses Red Hat Bugzilla #214765.)
4225 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
4226 allocating inode tables for some relatively rare odd disk sizes.
4227 (Addresses Red Hat Bugzilla #241767.)
4229 Add Catalan translation and update Dutch and Swedish translations
4230 from the Translation Project.
4232 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
4233 still had an issue when trying to figure out whether we need to
4234 byte-swap fast symlinks that contained extended attributes.
4236 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4237 (Addresses SourceForge Bug #1821333.)
4243 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
4245 Add "make check" to the RPM spec file
4247 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
4248 works correctly when the prefix is not the root directory.
4250 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
4251 clena up after themselves by deleting the test.img temporary file
4252 after completing the test.
4254 Fixed a corner case bug ext2fs_unlink() when trying to delete the
4255 first directory entry in a directory block and the last directory
4256 entry in the previous directory block is not in use. Fortunately
4257 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
4258 places where it is extremely unlikely to run into this corner case.
4260 Fix missing dependency which would cuase parallel builds to fail.
4261 (Addresses Sourceforge Bug #1842331.)
4263 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
4264 calling open(O_CREATE) with a missing mode parameter.
4266 Fix the test_ss.c in lib/ss so it can be used as an example
4267 application program for the library as well as a regression test
4270 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
4271 are properly passed back up through the call stack.
4273 E2fsprogs 1.40.2 (July 12, 2007)
4274 ================================
4276 A recent change to e2fsck_add_dir_info() to use tdb files to check
4277 filesystems with a very large number of filesystems had a typo which
4278 caused us to resize the wrong data structure. This would cause a
4279 array overrun leading to malloc pointer corruptions and segfaults.
4280 Since we normally can very accurately predict how big the the dirinfo
4281 array needs to be, this bug only got triggered on very badly corrupted
4284 Fix a bug in e2fsck which caused it to incorrectly salvange
4285 directories when the last entry's rec_len is bogusly too big. This
4286 resulted in a nonsense filesystem corruption to be reported, and
4287 required a second run of e2fsck to fully fix up the directory.
4289 Update tune2fs man page to include more discussion of reserved blocks
4290 (Addresses Launchpad bug #47817)
4292 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
4296 E2fsprogs 1.40.1 (July 7, 2007)
4297 ===============================
4299 Fix bug which could cause libblkid to loop forever. When revalidating
4300 a partition where there is obsolete information in /etc/blkid.tab, we
4301 end up freeing a the type tag without clearing dev->bid_type, causing
4302 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
4304 The Turkish translation has a bug in it where it has the translation
4305 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
4306 @E, recursively, forever, until the stack fills up and e2fsck core
4307 dumps. We fix this by making e2fsck stop @-expansions after a
4308 recursive depth of 10, which is far more than we need.
4309 (Addresses Sourceforge Bug: #1646081)
4311 Compile the default mke2fs.conf into mke2fs program. People are
4312 getting surprised by mke2fs creating filesystems with different
4313 defaults than earlier versions of mke2fs if mke2fs.conf is not
4314 present. So we now create a built in version of mke2fs.conf file
4315 which is used by mke2fs if the /etc/mke2fs.conf is not present.
4316 (Addresses SourceforgeBug: #1745818)
4318 Improve the config/parse_types.sh helper script. Fix a potential
4319 security problem if e2fsprogs is built as root (as Gentoo does!). In
4320 addition fix the script and how it is called from the configure script
4321 so that it does the right thing when cross-compiling. (Fixes Gentoo
4324 Update Vietnamese, French, and Dutch PO files from the Translation
4325 Project. Also created a new e2fsprogs.pot file for translator.
4327 Fix bogus strip permission errors when building under Debian. When
4328 building the e2fsprogs dpkg's, the dh_strip command emits a large
4329 number of error messages caused by the permissions not being right.
4330 So run dh_fixperms before running dh_strip.
4335 Add new function: profile_set_default(). This function sets the value
4336 of the pseudo file "<default>". If the file "<default>" had
4337 previously been passed to profile_init(), then def_string parameter
4338 will be parsed and used as the profile information for the "<default>"
4341 Fix mk_cmds's error reporting so that it is unambiguous that it is the
4342 mk_cmds script which is generating the error. (Obviates Gentoo patch:
4343 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
4345 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
4346 priority" environment variable that overrides all others, where as
4347 LANG is the lowest priorty environment variable. If LC_ALL is set, it
4348 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
4349 the all the rest are set. This will assure that the locale when
4350 running the test suites is the "C" locale. (Obviates Gentoo patch:
4351 e2fsprogs-1.38-tests-locale.patch)
4354 E2fsprogs 1.40 (June 29, 2007)
4355 ==============================
4357 Fix divide by zero error in blkid's NTFS probing logic.
4359 Add new blkid -g option which causes the blkid cache to be garbage
4362 Fix a bug in libblkid which could cause the internal field bid_type to
4363 become corrupted. Fortunately bid_type isn't used much, and bid_label
4364 and bid_uuid is only used by debugging code, so the impact of this bug
4367 Mke2fs will now store the RAID stride value when a filesystem is
4368 created with a requested RAID stride, and then use it automatically in
4371 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
4372 isn't too big. In some cases Lustre users have tried specifying an
4373 inode size of 4096 bytes, while keeping an inode ratio of one inode
4376 Improve sanity check in e2fsck's algorithm for finding a backup
4377 superblock, so that it won't accidentally find a superblock that was
4378 located in the journal, and then later reject it as being not a valid
4381 Fix e2fsck get_size logic so that it will work with the Linux floppy
4382 driver. The Linux floppy driver is a bit different from the other
4383 block device drivers, in that if the device has been opened with
4384 O_EXCL, it disallows another open(), even if the second open() does
4385 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
4387 Fix error checking of badblock's last-block and start-block arguments.
4388 (Addresses Debian Bug: #416477)
4390 Fix e2fsck so that it doesn't overwrite the backup superblocks when
4391 recovering a journal until the master superblock has been confirmed as

4395 that a partition contains an NTFS filesystem, and fetch the UUID and
4396 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:

4403 journal inode was cleared to due it being corrupt after finishing the
4406 Fix e2fsck so that it updates the journal inode if it is corrupted and
4407 the backup journal information from the superblock was successfully
4408 used to recover the filesystem.
4410 Fix e2fsck so that it checks all of the blocks in the journal inode
4411 for validity. The original code only checked the direct blocks to
4412 make sure the journal inode was sane. Unfortunately, if some or all
4413 of the indirect or doubly indirect blocks were corrupted, this would
4416 Add support in blkid to detect LUKS encrypted partitions.
4418 Add extra sanity checks for extended attributes in the case where the
4419 size is zero but the offset is very large.
4421 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
4422 and ext2fs_get_next_inode_full().
4424 Clarify the copyright licenses used by the various libraries in
4425 the top-level COPYING file (Red Hat Bugzilla: 166058)
4427 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
4429 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
4431 Remove check in e2fsck which requires EA's in inodes to be sorted;
4432 they don't need to be sorted, and e2fsck was previously wrongly
4433 clearing unsorted EA's stored in the inode structure.
4435 Allow mke2fs or tune2fs to create a substantially larger journal (up
4436 to 10,240,000 blocks).
4438 Fix MD superblock detection, and make sure the correct UUID is
4439 reported from the MD superblock.
4441 Fix a signed vs. unsigned bug in debugfs.
4443 Enhance debugfs's date parser so that it accepts integer values.
4445 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
4446 file with multiply claimed blocks is hard linked. or not at all if the
4447 root directory contains shared blocks
4449 Enhance debugfs so it can modify the block group descriptors using the
4450 command set_block_group_descriptor.
4452 Improve e2fsck's reporting of I/O errors so it's clearer what it was
4453 trying to do when an error happens
4455 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
4456 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
4457 #232663 and LTC Bugzilla: #27634)

4471 (Addresses LTC Bugzilla #27513)
4473 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
4474 field on the first pass.
4476 Fix e2fsck to set the file type of the '..' entry when connecting
4477 a directory to lost+found. (Addresses Lustre Bug: #11645)
4479 Enhance e2fsck to recover directories whose modes field were corrupted
4480 to look like special files. This is probably only useful in
4481 artificial test cases, but it will be useful if we ever do the "inodes
4482 in directory" idea for ext4.
4484 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
4487 Fix resize2fs parsing of size parameter (in sector units). This was
4488 actually a bug in libe2p's parse_num_blocks() function. When handling
4489 the 's' suffix, it was ignoring the blocksize information passed in
4490 from the caller and always interpreting the number in terms of a 1k
4491 blocksize. (Addresses Debian Bug: #408298)
4493 There was a floating point precision error which could cause e2fsck to
4494 loop forever on really big filesystems with a large inode count.
4495 (Addresses Debian Bug: #411838)
4497 Fix memory leak in ext2fs_write_new_inode()
4499 Add support for using a scratch files directory to reduce e2fsck's
4500 memory utilization on really big filesystems. This uses the TDB
4501 library. See the [scratch_files] section of the e2fsck.conf man page
4504 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
4505 platform (Addresses Debian Bug: #397044)
4507 Add explanatory message to badblocks that -n and -w are mutually exclusive
4508 (Addresses Debian Bug: #371869)
4510 Allow debugfs and dumpe2fs to support fs features under development.
4512 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
4513 ext2fs_open() , which allows application to open filesystes with features
4514 which are currently only partially supported by e2fsprogs.
4516 Allow unix_io to support offsets greater than 2G (Addresses
4517 SourceForge Bug: #1547922)
4519 Fixed overflow and signed/unsigned problems caused by the number of
4520 blocks or inodes exceeding 2**31 or being close to 2**32-1.
4522 Add support for unsigned directory hash calculations with hints in the
4523 superblock to fix cross-architectural portability for htree
4524 directories with filenames where the high 8th bit is set. (Addresses

4531 Require mke2fs -F -F for really dangerous operations, since -F is
4532 needed for less dangerous operations such as creating filesystems
4533 images in regular files, or creating filesystems on whole block
4534 devices. These relatively innocuous usages should NOT be confused
4535 with running mke2fs on an apparently-mounted or in-use filesystem.
4537 Allow the default inode size to be specified into the mke2fs.conf
4540 Make the smallest default journal size is big enough so that on-line
4541 resizing should always work.
4543 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
4546 Fix debugfs coredump when lsdel is run without an open filesystem

4549 Fix debugfs display bug us that bytes that have the high bit set are
4550 displayed as "ec" instead of "ffffffec".
4552 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
4554 Device mapper scanning wasn't working in the blkid library because the
4555 pathnames had an extra "/dev" when they were being probed.
4557 Add GFS/GFS2 support to the blkid library.
4559 Fix blkid support of empty FAT filesystem labels.
4561 Avoid recursing forever (or for a long time) when the blkid library
4562 searches for a device and there are symlinks to directories in /dev.
4564 Avoid unaligned halfword access in blkid when accessing FAT
4565 superblocks, as this will cause Sparc/Solaris systems to throw a

4575 the superblock. Omit by default printing superblocks that are likely
4576 found in located in an ext3 journal unless an explicit -j option is

4580 translation. (Addresses Debian bug: #411562)
4582 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
4583 determining a partition's size, since binary searching to determine
4584 the device doesn't work on FreeBSD.
4586 Documentation about UUID's is available in enough places, and it's
4587 awkward to deal with debian-legal's insanities. So I'm caving in the
4588 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
4589 don't have do the dfsg tarball. Also remove the rule that only tried
4590 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
4591 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
4593 Fix the info-dir line so that the menu name does not contain a .info
4594 prefix. First of all, it's ugly, secondly, it causes the install-info
4595 command to fail to remove the com_err info file from the
4596 /usr/share/info/dir file when the comerr-dev package is removed and
4597 purged. (Addresses Debian Bug: #401711)

4614 (Addresses Sourceforge Bug: #1565561)
4616 Remove unused variables and other lint/gcc -Wall cleanups
4618 Add check to ext2fs_get_device_size() so it will return EFBIG for for
4619 filesystems contained in regular files where the filesystem image size
4620 is returned by stat64().
4622 Set local environment variables to C so mk_cmds and compile_et always
4623 work. (Addresses SourceForge Bug: #1532177)
4625 Added the 64-bit byte swapping function ext2fs_swab64().
4627 Added two new helper functions to prevent 2**31/2**32-1 overflow
4628 problems: ext2fs_div_ceil() and e2p_percent().
4630 Create new ext2fs library inline functions ext2fs_group_first_block()
4631 and ext2fs_group_last_block() in order to calculate the starting and
4632 ending blocks in a block group.
4634 Create the generated files read-only to remind developers not to edit them.
4636 Add support for autoconf 2.60 (with backwards compatibility for older
4637 versions of autoconf).
4639 Added an "make rpm" target to top-level Makefile
4641 Added various FreeBSD portability fixes.
4643 Exclude mercurial files from the RPM build tree to speed up copy/build.
4645 Use root_sysconfdir to define the locations of mke2fs.conf and
4646 e2fsck.conf instead of using a hard-coded /etc pathname.
4648 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
4650 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
4652 If diff -u is supported, use it to report test failures.
4654 Updates/improvements to RPM spec file
4656 Add on-disk format definitions for the following new features:
4657 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
4658 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
4659 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
4661 Add a new make target "checked-failed" in the tests directory which
4662 reruns any failed tests
4664 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
4666 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
4667 pointer dereferences, memory leaks, etc. None were security-criticial
4670 Fix up usage and decrement error messages in the test_icount program
4672 Add debugging code to the com_err library; if the environment variable
4673 COMERR_DEBUG is set to 1, print out debugging messages as error tables
4674 are added and removed from the com_err library. If the
4675 COMERR_DEBUG_FILE environment variable is set (and the process is not
4676 setuid) the debugging messages may be redirected to a file.
4678 Change all of the e2fsprogs programs to use the newer add_error_table()
4679 and remove_error_table() interfaces instead of the much older
4680 initialize_*_error_table() function.
4682 Add TDB support into the ext2fs library. This allows us to have a
4683 guaranteed library we can count on always being present so we can
4684 store data in an on-disk database.
4686 Add support for using TDB to store the icount data, so we don't run out
4687 of memory when checking really large filesystems.
4689 Change the regression test suite so that it skips empty test directories.
4691 Define the l_i_iversion field in ext2_inode. The l_i_version field is
4692 now defined from the old l_i_reserved1 field in the ext2 inode. This
4693 field will be used to store high 32 bits of the 64-bit inode version
4696 Add Makefile production rule for e2fsprogs.spec in case it gets
4699 Add new function profile_get_uint() to allow for a clean way to fetch
4700 unsigned integers from the context.
4702 Add test to make sure the ext2 superblock structure is 1024 bytes.
4704 Fix typo in name of f_dup4 regression test
4706 Add new function blkid_gc_cache() which performs a garbage collection
4707 pass on the /etc/blkid.tab file.
4709 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
4710 general, only e2fsck (after the filesystem is clean), tune2fs, and
4711 resize2fs should change the backup superblocks by default. Most
4712 callers of ext2fs_open() should not be touching any superblock fields
4713 which require the backups to be touched.
4715 Add new function to libext2fs, ext2fs_default_journal_size(), which
4716 returns the default journal size.
4719 E2fsprogs 1.39 (May 29, 2006)
4720 =============================
4722 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
4723 between 2**31 and 2**32 blocks.
4725 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
4726 configure the filesystem features, blocksize, and inode_ratio for
4727 different filesystem types.
4729 Mke2fs will now create filesystems hash trees and on-line resizing
4730 enabled by default, based on the new /etc/mke2fs.conf file.
4732 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
4733 filesystem device node in exclusive mode to prevent accidents by
4734 system administrators. In the case of resize2fs and mke2fs, it will
4735 only use exclusive mode if the filesystem is not mounted.
4737 Fixed a bug in mke2fs which caused it to to fail when creating the
4738 resize inode for large filesystems. (Addresses Debian Bug #346580)
4740 When allocating space for the RAID filesystems with the stride
4741 parameter, mke2fs will now place each portion of the group's inode
4742 table right up after the superblock (if present) in order to minimize
4743 fragmentation of the freespace.
4745 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
4746 efficiently by writing the inode and block bitmaps in one pass, thus
4747 reducing the number of disk seeks required.
4749 Add support for on-line resizing to resize2fs.
4751 Fix blkid library so that logic to determine whether or not a device's
4752 cached information in /etc/blkid.tab needs to be verified or not
4753 doesn't get confused by a system clock which is insane (for example,
4754 if the battery is dead on a Macintosh running PPC Linux. (Addresses
4755 Red Hat Bug: #182188)
4757 The blkid library will now store the UUID of the external journal used
4758 by ext3 filesystems, so that in the future, the userspace mount binary
4759 can use this to find the location of the external journal and pass
4760 this information to the kernel.
4762 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
4763 control how various options should be handled. See the e2fsck.conf
4764 man page for more details. (Addresses Debian Bug: #150295)
4766 E2fsck now prints an explanatory message when delaying a filesystem
4767 check when the system is running on battery. (Addresses Debian Bug:
4770 E2fsck will detect if the superblock's last mount field or last write
4771 field is in the future, and offer to fix if so. (Addresses Debian Bug
4772 #327580) These problems will be fixed automatically in preen mode
4773 since Debian's boot sequence bogusly doesn't set the time correctly
4774 until potentially very late in the bootup process, and this can cause
4775 false positives which will cause users' systems to fail to boot.
4776 (Addresses Debian Bugs #343662 and #343645)
4778 E2fsck now checks to see if the superblock hint for the location of
4779 the external journal is incorrect, and if so, offer to update it.
4780 (Addresses Debian Bug: #355644)
4782 Fix e2fsck from segfaulting on disconnected inodes that contain one or
4783 more extended attributes. (Addresses Debian Bug: #316736, #318463)
4785 E2fsck will stop and print a warning if the user tries running a
4786 read/write badblocks test on a read-only mounted root filesystem.
4788 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
4789 C. Thompson for pointing these out; they were originally found using
4792 When resizing a file containing a filesystem, resize2fs will expand or
4793 truncate a file as necessary. (Addresses Debian Bug: #271607)
4795 Resize2fs will now automatically determine the RAID stride parameter that
4796 had been used to create the filesystem, and use that for newly created
4797 block groups. The RAID stride parameter may also be manually specified
4798 on the command line using the new -S option to resize2fs.
4800 Fix mke2fs so that it correctly creates external journals on
4801 big-endian machines (such as a S/390).
4803 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
4804 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
4805 Chambraud for pointing this out.)
4807 Dumpe2fs will now print the size of the journal (if present).
4809 Fix debugfs's set_inode_field command so it can properly set the frag,
4810 fsize, uid_high, gid_high, and author fields in the inode instead of
4811 silently failing, and so that setting the i_size actually sets i_size
4814 Add a new debugfs command, set_current_time, which sets fs->now so
4815 that regression test suites can repeatedly modify the filesystem's
4818 Fix a bug in debugfs's icheck which would incorrectly report the owner
4819 of an extended attribute block.
4821 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
4822 print a usage message when an illegal option character is given.
4824 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
4825 so it won't core dump. (Addresses SourceForge bug #1424311)
4827 Fix mklost+found so that it creates a full-sized directory on
4828 filesystems with larger block sizes.
4830 Fix a file descriptor leak in blkid library.
4832 Fix a display bug in "badblocks -sv" so that the done message properly
4833 clears the block number at the end of the test. (Addresses Debian Bug
4836 Allow fractional percentages to the -m option in mke2fs and tune2fs
4837 (Addresses Debian Bug: #80205)
4839 Use fstat/fstat64 in getsize.c if the the target is a regular file,
4840 instead of attempting to do a binary search. Fix some fd leaks in
4843 Add support for device mapper library to the blkid library to ensure
4844 that the "best" (i.e., leaf) device is probed by the blkid library.
4846 Fix the blkid library so that it notices when an ext2 filesystem is
4849 Improve the blkid's library VFAT/FAT detection; it now understands
4850 labels stored in the root directory, and is more paranoid about
4851 checking the FAT superblock values.
4853 Fixed a fd leak in the uuid library which was causing problems for the
4854 LVM tools. (Addresses Debian Bug: #345832)
4856 Add support for the reiser4 and software suspend partitions to the
4857 blkid library. Also add support for extract the label from iso9660
4860 Fix a compile_et bug which miscount the number of error messages if
4861 continuations are used in the .et file.
4863 Add extra sanity checks to protect users from unusual cirucmstances
4864 where /etc/mtab may not be sane, by checking to see if the device is
4865 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
4868 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
4869 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
4871 Fix use-after-free bug in e2fsck when finishing up the use of the
4872 e2fsck context structure.
4874 Fixed spelling mistakes, typos, and otherwise clarified man pages and
4875 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,
4876 #312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394,
4879 Fixed various Debian packaging issues --- see debian/changelog for
4880 details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
4881 #310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,
4888 Update config.guess and config.sub to latest version (2006-02-23) from
4891 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
4892 Bugs: #360661, #360317)
4894 Fixed the Makefile so that they work correctly on newer versions of
4895 GNU make (i.e., 3.81).
4897 Add valgrind support to the regression test suites, and eliminate
4898 false positives from valgrind.
4900 Add a regression test suite for the blkid library.
4902 Fix a fencepost error in resize2fs caught by valgrind.
4904 Fix compiler warnings about missing memcpy prototypes.
4906 We no longer have the sparc assembly code in the header file any more,
4907 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
4908 break compiles on the sparc architectures when using gcc.
4910 In the libext2fs library, add the new field fs->now which if non-zero
4911 is used instead of the system time when setting various filesystem
4912 fields (last modified time, last write time, etc.)
4914 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
4915 ext2fs.h which is needed since the inline functions use memcpy().
4916 (Addresses Sourceforge Bug #1251062)
4918 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
4919 the build system when building files in the util directory which are
4920 needed during the build process. This avoids potential problems when
4921 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
4922 are not recognized as valid by the host compiler. (Addresses
4923 Sourceforge Bug #1261547)
4925 Clean up the blkid library by making the superblock and generic i/o
4926 functions to be more generic. Clean up interface to the probe
4927 function, and fix memory leak. Finallly, remove an unneeded reference
4928 to probe.h in the lib/blkid/resolve.c
4930 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
4931 of invalid block #'s.
4933 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
4934 indicate that the the function read/writes the memory location.
4936 Fix various gcc -Wall complaints.
4938 Add a dependency to make sure that the subdirectories are created
4939 before creating all of the object files, in order to address parallel
4940 build problem in the library Makefiles. (Addresses Sourceforge Bug:
4943 Add $(LDFLAGS) to the command line argument when generating an ELF or
4944 Solaris shared library, to allow cross-compile and other builds that
4945 might need to specify -L paths to needed libraries. (Addresses
4946 Sourceforge Bug #1261549)
4948 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
4949 intended for testing purposes. It allows an ext2/ext3 developer to
4950 create very large filesystems using sparse files where most of the
4951 block groups are not initialized and so do not require much disk
4952 space. Eventually it could be used as a way of speeding up mke2fs and
4953 e2fsck for large filesystem, but that would be best done by adding an
4954 RO_COMPAT extension to the filesystem to allow the inode table to be
4955 lazily initialized on a per-block basis, instead of being entirely
4956 initialized or entirely unused on a per-blockgroup basis.
4958 Fix backwards compatibility so e2fsprogs will better compile on Linux
4961 Make test scripts more robust against locale-related environment variables
4963 Fix type warning problem with sizeof() in ext2fs_open2().
4965 Fix type warning problem with time_t in debugfs.
4968 E2fsprogs 1.38 (June 30, 2005)
4969 ==============================
4971 Fix blkid's test programs (built with "make check") compile correctly
4972 even without "configure --enable-blkid-debug".
4974 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
4975 type aliasing rules on newer gcc compilers. (Addresses Red Hat
4978 Fix com_err library to make it more compatible with recent changes
4979 made to the com_err library in MIT Kerberos V5 version 1.4.
4980 (Addresses Sourcefroge Bug #1150146)
4982 General cleanup of messages printed by e2fsprogs programs for grammar,
4983 consistency, and to make life easier for translators. Fixed a few
4984 strings containing English that had not been marked as needing
4985 translations. Removed strings that do not need to be translated, to
4986 make life easier for translators.
4988 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
4989 test to see if a device appears to be in use instead of just relying
4990 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
4992 Fix portability problem in the filefrag program affecting platforms
4993 where the size of an integer is smaller than the size of a long.
4994 (Addresses Debian Bug #309655)
4996 Mke2fs will now use a larger journal by default for filesystems
4997 greater than 4GB. (128 MB instead of 32MB).
4999 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
5000 unless forced. This is to avoid signed vs. unsigned kernel bugs in
5001 block numbers that still need to be fixed.
5003 The blkid program has a new option which will more efficiently search
5004 for device when it is known (or expected) that only one matching
5005 device will be found in the system, such as when doing a lookup by
5008 Debian's e2fsprogs-specific initrd fragment will avoid including
5009 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
5010 and LD_LIBRARY_PATH, and filtering out libraries found in
5011 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
5013 Fixed a potential portability issue in the blkid programs for
5014 architectures where the char type is unsigned. (Addresses Sourceforge
5017 Fix a bug in filefrag so that it doesn't falsely count an extra
5018 discontinuity when the first block found is an indirect block.
5019 (Addresses Debian Bug #307607).
5021 Fix blkid's recognition of cramfs filesystems, and enhance it to be
5022 able to handle cramfs labels.
5024 Fix debugfs's stat command to not core dump when a filesystem is not
5027 Fix e2fsck's handling of error conditions caused by the resize inode
5028 claiming blocks that are also used by other inodes, a filesystem
5029 corruption which was commonly caused by a bug in Fedora Core 3's
5032 Fixed bug in filefrag which caused it to fail on non-ext2/3
5033 filesystems. (Addresses Debian Bug: #303509)
5035 If the superblock last mount time indicates that the system clock may
5036 not be accurate, then e2fsck will omit checking inodes' deletion time
5037 field for indications of a potential corrupted orphaned inode list.
5038 (Previously e2fsck only ommited these LOW_DTIME checks when the
5039 superblock's last write time looked insane.)
5041 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
5042 (Addresses Debian bug #302200)
5044 Make the blkid library more paranoid about being run from setgid
5045 programs, and to use __secure_getenv() from libc if it is available.
5047 Fixed spelling mistakes, typos, and otherwise clarified man pages.
5048 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
5049 and Sourceforge Bug: #1189803)
5051 Updated and fixed translations.
5053 Fixed various Debian packaging issues --- see debian/changelog for
5059 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
5060 changed to take an unsigned int for the bit number. Negative bit
5061 numbers were never allowed (and didn't make any sense), so this should
5062 be a safe change. This is needed to allow safe use of block numbers
5063 greater than or equal to 2**31.
5065 The compile_et program will avoid recreating generated foo_err.c and
5066 foo_err.h files if no changes are necessary. The compile_et program
5067 will also atomically replace these files to avoid a potential parallel
5068 build race problem on SMP systems. (Addresses Sourceforge Bug:
5071 Added a new function to the blkid library, blkid_probe_all_new(),
5072 which only probes newly added disk devices, and change
5073 blkid_find_dev_with_tag() to use this function so that when a
5074 requested tag is not found, devices that were previously not checked
5075 are searched before searching all devices in the system.
5077 Added new functions to the blkid library, blkid_dev_set_search() and
5078 blkid_dev_has_tag().
5080 E2fsck's problem strings can now use @m and @n as abbrevations for
5081 "multiply-claimed" and "invalid", respectively.
5083 The e2fsprog.pot file now has an explanation of how the @-expansion
5084 and %-expansion works, and strings in e2fsck/problem.c which contain @
5085 characters now have comments in e2fsprogs.pot with the @-expansion to
5086 make life easier for translators.
5088 Fixed missing return values in the ext2fs library which could cause it
5089 to return random garbage in certain error conditions.
5091 Allow the current time to be overriden via the E2FSCK_TIME environment
5092 variable for use in regression tests.
5094 The test scrpit driver program now exits with a non-zero status if
5095 there any of its test that it ran failed.
5097 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
5100 Fixed "make check" so that it compiles correctly even when e2fsprogs'
5101 header files have not be installed in the system include directories.
5102 (Addresses Sourceforge Bug: #1180572)
5104 Fixed gcc -Wall nits.
5107 E2fsprogs 1.37 (March 21, 2005)
5108 ===============================
5110 Add support for checking the validity of Extended Attributes stored in
5113 Add support for dumping the contents of large inodes to debugfs,
5114 including the extended attributes stored in inodes.
5116 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
5117 when we create a new inode we make sure that the extra information in
5118 the inode (any extra fields in a large inode and any ea-in-inode
5119 information) is initialized correctly. This can take place when
5120 mke2fs creates the root and lost+found directory, when e2fsck creates
5121 a new root inode or a new lost+found directory, and when the user uses
5122 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
5123 create inode could inherit garbage (or old EA information) from a
5124 previously deleted inode.
5126 Fixed a bug in e2fsck so it would notice if a file with an extended
5127 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
5130 Added support to filefrag to detect files which are using the new
5131 experimental file extents format, and use the non-ext2 algorithm in
5132 that case. Fixed a bug to avoid reporting a false discontinuity if
5133 there is one or more unallocated blocks at the beginning of a file.
5135 Duplicated a check for noticing whether or not the number of blocks
5136 (given a certain blocksize) is greater than 2**32 when the
5137 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
5138 allows mke2fs to automatically use a larger blocksize when creating a
5139 filesystem on a very large device when run on systems that do not
5140 support BLKGETSIZE64.
5142 Fix the I18N build which was broken in e2fsprogs 1.36 because the
5143 build system had been switched to treat the .gmo files as shipped
5144 files (for backwards compatibility with systems that have older GNU
5145 I18N tools installed), but the gen_tarball.in script was still
5146 removing the .gmo files from the official source distribution.
5148 Fixed various Debian packaging issues --- see debian/changelog for
5149 details. (Addresses Debian Bugs ##296769, #299341)
5154 Added new functions to the e2p library which convert between a string
5155 and os_type: e2p_os2string() and e2p_string2os(), and used them to
5156 make the generated binaries more compact.
5158 Fixed a compile-time error on Darwin systems.
5160 Cleaned up the lib/ext2fs Makefile slightly.
5163 E2fsprogs 1.36 (February 4, 2005)
5164 =================================
5166 All of the patches that were applied to Fedore Core 3's
5167 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
5168 lot of bug fixes first. Users of Fedora Core 3 are strongly
5169 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
5171 Add support for filesystem with the online resizing via resize inode
5172 feature. Fixed numerous bugs from the Fedora patches. The Fedora
5173 patches also didn't bother to do any consistency checking on the
5174 resize inode, or add any tests to the regression test suite. The "-R
5175 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
5176 being listed in mke2fs's usage message. All of these shortcomings
5177 have been corrected.
5179 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
5180 program. In order to do this, the user must run the commands:
5182 debugfs -w /dev/hdXXX -R "features ^resize_inode"
5183 e2fsck -f /dev/hdXXX
5185 Optionally, the ext2prepare command can be used to re-enable online
5186 resizing after the filesystem has been fixed.
5188 The fsck program will now accept an optional filedescriptor argument
5189 to the -C option. (The Fedora version of this patch would sometimes
5190 cause fsck to ignore a parameter on fsck's command line in some rare
5193 Make sure e2fsprogs doesn't write garbage into the reserved portion of
5196 Make sure resize2fs releases the blocks belonging to the old inode
5197 table blocks when moving the inode table. (Addresses Debian Bug:
5200 Skip the r_resize_inode test if resize2fs is not compiled (due to
5201 configure --disable-resizer)
5203 E2fsck now checks the summary filesystem accounting information, and
5204 if any of the information is obviously wrong, it will force a full
5205 filesystem check. (Addresses Debian Bug #291571)
5207 Fix e2fsck to not complain when the resize_inode feature is enabled,
5208 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
5211 Fix e2fsck to note delete symlinks that contain an extended attribute
5212 after the ext_attr feature flag has been cleared. (Addresses Red Hat
5215 Add new utility program, copy_sparse.c, which is very useful
5216 for dealing with large sparse files (such as e2image files).
5218 Add support for jnl_blocks[] for debugfs's set_super_value.
5220 Fix filefrag so that it works correctly with sparse files.
5222 Filefrag -v will print first and last blocks.
5224 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
5227 Add mke2fs support so that it can support filesystems larger than 4TB
5228 automatically, by retrying with a 4k blocksize if the device size is
5229 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
5232 Change blkid to test for NTFS first because Windows sometimes doesn't
5233 clear enough of the parition to confuse the probing routines into
5234 thinking the old filesystem type is still valid. (Addresses Debian
5237 Add support for swap partition label and uuid's in the blkid library.
5239 Add support to the blkid library to recognize Oracle ASM volumes.
5241 Make blkid -t display all devices that match the specified criteria,
5242 not just the first one, and work more consistently when the blkid
5243 cache file is not available or set to /dev/null. (Addresses Debian
5244 Bug #290530 and #292425)
5246 Badblocks will now correctly display block numbers greater than
5247 999,999,999 in its progress display.
5249 The tune2fs program will not allow the user from setting a ridiculous
5250 number of reserved blocks which would cause e2fsck to assume the
5251 superblock was corrupt. E2fsck's standards for what is a ridiculous
5252 number of reserved block has also been relaxed to 50% of the blocks in
5255 The blkid library will return vfat in preference to msdos, and ext3 in
5256 preference to ext2 (if the journalling flag is set) so that mount will
5257 do the right thing. (Addresses Debian bug #287455)
5259 Mke2fs will now use the -E option for extended options; the old -R
5260 (raid options) option is still accepted for backwards compatibility.
5261 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
5263 Mke2fs will now accept a size in megabytes, gigabytes, and other units
5264 (via "32m" or "4g" on the command line) if the user finds this more
5265 convenient than specifying a block count.
5267 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
5268 cache conherency problem.
5270 Debugfs now supports a new command, set_inode_field, which allows a
5271 user to manually set a specific inode field more conveniently, as well
5272 as set entries in the indirect block map.
5274 Debugfs's set_super_value command has been enhanced so that the user
5275 can set most superblock fields, including the date/time fields and
5276 some of the more newsly added superblock fields.
5278 E2fsprogs programs now accept an offset to be passed to the file
5279 specifiers, via the syntax: "/tmp/test.img?offset=1024".
5281 E2fsprogs programs will now accept blocksizes up to 65536; kernel
5282 support on the x86 doesn't exist for now, but it can be useful on
5283 other architectures with page sizes greater than 4k. There are 2.6
5284 kernel patches out there which enable this, but they are of this
5285 writing still experimental.
5287 The e2image command now takes the -s option which will scramble
5288 directory entries for raw image files.
5290 Fix a file descriptor leak in the filefrag program.
5292 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
5295 Fix bug in debugfs where kill_file would lead to errors when deleting
5296 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
5298 Fix bug in the blkid library when detecting the ocfs1 filesystem
5300 Remove obsolete EVMS 1.x and a.out DLL support.
5302 E2fsck will attempt to recover from a journal containing illegal blocks.
5304 Fixed two potential ordering constraint problems in e2fsck which might
5305 cause the filesystem to be corrupted if e2fsck is interrupted during a
5306 (extremely narrow) race window. Thanks to Junfeng Yang from the
5307 Stanford Metacompilation group for pointing this out.
5309 Fixed bug in e2fsck where it would not accurately detect whether or
5310 not the system is running on adaptor if the ACPI device representing
5311 the AC adapter didn't correspond to the what was used on IBM
5314 Change e2fsck to accept directories greater than 32MB.
5316 Fix e2fsck so that a checkinterval of zero disables a time-based check
5319 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
5320 to the PAGER environment variable. (Addresses Debian Bug #239547)
5322 Tune2fs will not mark rewrite the superblock if the feature bitmasks
5325 The debugfs program will set the filetype information when creating a
5328 Add debugfs -d option to use a separate source of data blocks when
5329 reading from an e2image file.
5331 Add e2image -I option which allows the e2image metadata to be
5332 installed into a filesystem.
5334 Fixed bug in the badblocks program which caused "done" to always
5335 appear in english even when a translation was available. (Addresses
5338 The blkid program has a new option -o which controls the output format
5339 of the blkid program; this is makes blkid more convenient to use in
5342 Fix a minor bug in uuid library, which was not using the full 14 bits
5343 of clock sequence when generating UUID's.
5345 Fix a Y8.8888K problem in the uuid library.
5347 Logsave now creates a new session id for itself to avoid getting
5348 killed by init whan transitioning between init levels.
5350 Change the licensing of the UUID library to be the 3-clause BSD-style
5351 license; this allows Apple to use the uuid library in Darwin.
5353 Add ocfs and ocfs2 probe support into the blkid library.
5355 Fix a memory and file descriptor leak in the blkid library.
5357 The blkid library will revalidate the device if the system time is
5358 earlier than last verification time of the device, since that
5359 indicates that the system time is probably nottrustworthy.
5361 The blkid library will override the default location of the blkid.tab
5362 file by the BLKID_FILE environment variable, if it is available.
5364 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
5366 Add various portability fixes for lame new versions of glibc, Darwin
5367 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
5368 Bugs #239934, #264630, #269044, #255589, #289133)
5370 Add support for Windows 9x/NT under Cygwin.
5372 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
5373 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
5375 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
5377 Update the rpm spec files so that it works better with Fedora core 2
5380 Fixed various Debian packaging issues (see debian/changelog). In
5381 particular, fixed the Debian initrd scripts. (#241183, #248050,
5388 Fixed various gcc -Wall warnings.
5390 The uuid library now has new functions uuid_unparse_upper() and
5391 uuid_unparse_lower() which forces the case of the hex digits to be
5392 upper case, or lower case.
5394 The build process has been speeded up by enhancing the subst program
5395 to update the modtime on the generated files even when the generated
5396 file hasn't changed.
5398 The uuid library now uses C99 stdint.h types instead of custom types.
5400 Updated config.guess and config.sub with newer versions from the FSF.
5402 Removed out of date .cvsignore files from the source distribution.
5404 The ext2fs_unlink() function will return an error if both the name and
5405 inode number are unspecified, to avoid doing something surprising
5406 (such as unconditionally deleting the first directory entry).
5407 Directory entries are now deleted by coalescing them with the previous
5408 directory entry if possible, to avoid directory fragmentation. This
5409 is not an issue with the e2fsprogs suite, but may be a problem for
5410 some of the users of libext2fs, such as e2tools.
5412 Add support for version numbers of the form "1.36-rc1".
5414 Fix build of mke2fs.static.
5416 Add basic ext2fs library support for large (EA in inode) inodes.
5418 The test_io mechanism can now abort after n reads or writes to a
5419 particular block. The block is specified by TEST_IO_BLOCK environment
5420 variable, and the read/write count by the TEST_IO_READ_ABORT and
5421 TEST_IO_WRITE_ABORT environment variables. The block data is now only
5422 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
5424 UUID_DEFINE() in the uuid library now creates a static variable, with
5425 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
5426 be used in header files.
5428 Add support for the install-strip and install-shlibs-strip targets, as
5429 suggested by the GNU coding guielines. "make install" no longer
5430 strips the binaries which are installed.
5432 Remove support for the --enable-old-bitops configure option which was
5433 only for very old sparc systems.
5435 Remove support for --enable-clear-htree; this was only needed during
5436 the early development of the htree patch.
5438 Use Linux-kernel-style makefile output so it is easier to see compiler
5441 Update gettext files to version 0.14.1.
5443 Update to use autoconf 2.5x.
5445 Improved support for compiling e2fsprogs under dietlibc.
5447 Make e2fsprogs portable to Solaris and FreeBSD systems.
5449 Add blkid_verify(), blkid_get_library_version(), and
5450 blkid_parse_version_string() functions to the blkid library.
5452 Add pkg-config files for e2fsprogs's libraries.
5454 Fix "make uninstall" to so that it removes everything that is installed.
5456 Add a configure --enable-maintainer-mode option which enables the
5457 makefile rules to rebuild the configure script from configure.in, and
5458 to reubuild the .gmo files in po directory.
5460 Drop the sparc assembly bitwise operations; it's less efficient
5461 than the GCC 3.4 compile code and triggers compiler warnings on
5462 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
5463 (Addresses Debian Bug #232326)
5466 E2fsprogs 1.35 (February 28, 2004)
5467 ==================================
5469 E2fsck has a new -k option, which in conjunction with the -c options,
5470 preserves the existing badblocks list.
5472 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
5474 E2fsprogs will now deal correctly with symlinks that contain
5475 extended attribute information, which can be created using SE Linux.
5476 (Addresses Debian Bug #232328)
5478 Remove a double longjump into an invalid stack frame bug in e2fsck.
5479 (This was during an abort sequence, which normally worked on Linux and
5480 caused a core dump on other operating systems.)
5482 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5483 (the NLS library will replace "" with the .po header information).
5485 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
5486 dump due to a division by zero error. (Addresses Debian bug #207082)
5488 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
5489 when reconnecting a directory requires creating a lost+found
5490 directory. (Addresses Debian bug #219640).
5492 Fixed a bug where e2fsck would bomb out if a journal needed to be
5493 replayed when using an alternate superblock.
5495 E2fsck will give an extra grace period before actually forcing a check
5496 if the laptop is running on battery. The next time fsck runs while
5497 the system is on the AC mains, or after the grace period is exceeded,
5498 the filesystem will be checked. (Addresses Debian bug #205177)
5500 E2fsck will inform the user when there are 5 or fewer mounts before a
5501 filesystem check will be forced. (Addresses Debian bug #157194)
5503 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
5504 We now correctly handle the case where there is an overlap between a
5505 block group descriptor or a superblock and a bad block indirect block.
5506 In the case where the indirect block is corrupted, we now suggest
5509 Fix byte swap bugs in e2fsck that caused the journal backup location
5510 in the superblock and symlinks created by SE Linux to be cleared
5511 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
5513 E2fsck -c now replaces the current list of bad blocks with the ones
5516 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
5517 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
5519 Fix a potential bug in e2fsck which could cause it to core dump when
5520 trying to print the location of the backup superblock.
5522 Protect against a potential core dump in e2fsck when printing a
5523 message about backup superblocks.
5525 Add support for backing up the journal inode location in the
5526 superblock. E2fsck will automatically save the journal information in
5527 the superblock if it is not there already, and will use it if the
5528 journal inode appears to be corrupted. ext2fs_add_journal_inode()
5529 will also save the backup information, so that new filesystems created
5530 by mke2fs and filesystems that have journals added via tune2fs will
5531 also have journal location written to the superblock as well.
5532 Debugfs's logdump command has been enhanced so that it can use the
5533 journal information in the superblock.
5535 E2fsck will now update all superblocks when moving the journal inode.
5537 Shrink the size of the e2fsck executable by moving some initialized
5538 variables to the BSS segment.
5540 E2fsck will avoid printing the ^A and ^B characters which bracket the
5541 progress bar when stdout and stdin are a tty device instead of a pipe
5542 to another program. (Addresses Debian bug #204137)
5544 Debugfs's mkdir command will automatically expand the directory if
5545 necessary. (Addresses Debian Bug: #217892)
5547 Fixed a bug in debugfs so that copying a file from /dev/null uses the
5548 correct mode bits. (Addresses Debian Bug: #217456)
5550 If the environment variables DEBUFS_PAGER and PAGER are not set,
5551 debugfs now searches for the appropriate pager to use, beginning with
5552 /usr/bin/pager, and then falling back to 'more' and 'less'.
5553 (Addresses Debian bug #221977)
5555 Debugfs will now support 2.6 device numbers where the major or minor
5556 number may be larger than 255. (Addresses Sourceforge bug #865289)
5558 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
5560 Chattr now stops processing options when it sees '--'. (Addresses
5563 Fix regression tests so they work correctly when e2fsprogs is compiled
5564 with configure --disable-htree.
5566 Fix bug in uuid library when there is no network card and the library
5567 is generating a time-based uuid. The random MAC address was not
5568 correctly generated to be a multicast address.
5570 Add compile_et extensions from Heimdall that were missed the first time
5573 Fix bug in badblocks when using O_DIRECT; we need to make sure that
5574 we're reading from an offset which is page aligned. For read-only and
5575 read-write tests, we try to recover after an error so that we can
5576 continue reading on page-aligned boundaries. (Addresses Debian Bug
5579 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
5582 Updated and clarified various man pages. (Addresses Debian Bug
5583 #206845, #222606, #214920, #232406)
5585 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
5587 Fixed various Debian packaging issues (see debian/changelog).
5592 Fixed a build problem so that e2fsprogs would compile with the
5593 --enable-profile option to configure selected. (Addresses Sourceforge
5596 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
5597 Bugzilla Bug #112448)
5599 Centralize code which calculates the location of the superblock
5600 and block group descriptors so that it is in a single library routine.
5602 Added two new functions, ext2fs_file_open2() and
5603 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
5605 Fix compile_et to output the correct prototype for
5606 initialize_xxx_err_table_r() in the header file. (Addresses Debian
5609 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
5611 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
5612 present. This is for when we try stuffing an int into void * pointer.
5614 Fix type-punning which can cause gcc 3.x to miscompile code by getting
5615 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
5616 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
5617 **'. The EVMS code uses an ugly union approach since we don't want to
5618 modify the EVMS interfaces.
5620 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
5621 aid build process on systems can use invoke GNU make as "gmake".
5623 Added regression testing for mke2fs.
5625 Fixed gcc -Wall nitpicks.
5627 Fixed various compiler warnings.
5629 Add portability fixes for FreeBSD and for using fsctl under Darwin to
5630 support ext2 ioctl's.
5633 E2fsprogs 1.34 (July 25, 2003)
5634 ===============================
5636 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
5637 a tight loop while waiting for a child fsck to exit in some cases.
5638 This burns CPU times which slows down the low-level filesystem check.
5640 Added code to mke2fs to assure that the default block size for a
5641 filesystem is at least as big as the sector size of the device, if it
5644 Changed mke2fs and resize2fs to round the default size of a filesystem
5645 to be an even multiple of the VM pagesize in order to avoid a Linux
5646 kernel bug introduced when the storage of the buffer cache was moved
5647 into the page cache.
5649 Mke2fs will warn the user when creating a filesystem with journaling
5650 and a blocksize greater than 4096. (Addresses Debian bug #193773)
5652 Fixed a bug in resize2fs which caused it to fail on filesystems with a
5653 non-empty bad block list. Resize2fs now discards any blocks on the
5654 badblock list which are no longer part of the filesystem as the result
5655 of a filesystem shrink. (Note: this means that shrinking and then
5656 enlarging a filesystem is no longer a reversible operation;
5657 information about bad blocks in the part of the filesystem which is to
5658 be chopped off will be lost.)
5660 Changed resize2fs so the user can use prefixes to specify the units of
5661 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
5662 and to make the error and informational messages explicitly display
5663 the blocksize used by the filesystem, in order to avoid confusion.
5664 (Addresses Debian bug: #189814)
5666 Added a new debugfs command, dump_unused, which dumps the contents of
5667 all unused blocks to stdout. (Useful as an emergency try-to-find
5668 deleted data command.)
5670 Added a new debugfs command, imap, which prints the location of a
5671 specified inode in the inode table.
5673 Fixed a bug in the badblocks program which caused it to use one bit of
5674 randomness in its non-destructive read/write test, instead of using a
5675 full 8 bits of randomness.
5677 Added a new option (-t) to badblocks, which allows the user to control
5678 the test pattern(s) used when checking a disk.
5680 The blkid probe function now more correctly detects UDF filesystems.
5682 Fixed a bug in the blkid library which caused it to not update its
5683 cache if a filesystem changes from having a label to not having a
5686 Fixed a bug in the blkid library wihch could avoid an infinite loop
5687 in blkid_find_dev_with_tag() if /proc is not mounted and there the
5688 /etc/blkid.tab file has not yet been created.
5690 Fixed the badblocks program so that the destructive read/write test
5691 honors the -c option, and to use O_DIRECT when possible to avoid
5692 thrashing the system block buffer cache.
5694 Fixed various NLS issues.
5695 - Added Czech and Swedish translations
5696 - Removed testing NYC translation
5697 - Fixed NLS support for message abbrevations in e2fsck
5698 - Remove de-utf.po, since we shouldn't have two versions using different
5700 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
5701 simplify the statistics reporting in e2fsck.
5703 Changed configure.in so that its defaults for *BSD systems no longer
5704 build an fsck wrapper, and not to install in /usr/local by default.
5706 Fixed some minor spelling errors/typo's in e2fsck and the configure
5709 Fixed various Debian packaging issues (see debian/changelog).
5711 Updated and clarified man pages. (Addresses Debian Bug #195616)
5716 Fix gcc -Wall nitpicks.
5718 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
5719 NLS support by default. (Added partial workaround for gettext/Darwin
5720 incompatibility problems.)
5722 Added full MIT KRB5 and Himdall compaibility support to the com_err
5723 library and the compile_et program. (Addresses Debian bug #191900)
5725 Added the blkid_known_fstype() function to the blkid library, which
5726 returns true if it is passed a filesystem type which is recognized by
5727 the blkid probing functions.
5729 Improved the documentation for the blkid library.
5731 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
5732 returns the hardware sector size of a device, if it is available.
5734 Added a dependency in the blkid library's .so file to the uuid
5735 library, since the former uses the latter. (Addresses Debian bug
5738 Added --with-diet-libc and --disable-evms to the configure script.
5740 Fixed a minor memory leak in the badblocks program.
5742 Fixed a portability problem in tune2fs --- not all systems have strptime().
5744 Fixed a portability problem in debugfs with the use of getopt() more
5745 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
5748 Add support Windows support to ext2fs_get_device_size().
5750 Added (normally disabled) debugging code to the Unix I/O manager which
5751 causes it to disable all userspace caching if the NO_IO_CACHE is
5754 Changed the test I/O manager so it can always be linked into e2fsck,
5755 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
5756 configure script. The test I/O manager will only print any debugging
5757 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
5758 variables are set, which specifies which I/O operations are logged and
5759 a block number to watch, respectively. The log messages are sent to
5760 stderr by default, unless a filename is specified via the
5761 TEST_IO_LOGFILE environment variable.
5764 E2fsprogs 1.33 (April 21, 2003)
5765 ===============================
5767 Added a new utility program, logsave, which captures the output of a
5768 command in a log file, even if the containing directory hasn't been
5769 mounted yet (in which case the it saves the output in memory until it
5770 can write out the logfile). This is useful for capturing the
5771 output of fsck during the boot sequence.
5773 Fixed some portability problems that were causing problems under
5774 the Cygwin32 environment.
5776 Mke2fs now interprets a negative number to the -b option as a minimum
5779 Fixed a bug in mke2fs which was incorrectly checking the argument to
5780 the -g option if the default block size was used. (Addresses Debian
5783 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
5784 it can not find filesystem checkers for jfs, reseirfs, and xfs.
5786 E2fsck now updates the global free block and inode counters from the
5787 block group specific counters quietly. This is needed for an
5788 experimental patch which eliminates locking the entire filesystem when
5789 allocating blocks or inodes; if the filesystem is not unmounted
5790 cleanly, the global counts may not be accurate.
5792 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
5793 2.0 is not yet supported; this only pulled in the bug fixes: fixed
5794 possible hangs caused by bugs in calling waitpid, and not setting the
5795 pipe to non-blocking mode; also fixed a file descriptor leak; made
5796 sure all functions call log entry/exit functions.)
5798 Badblocks now flushes its output file as bad blocks are discovered.
5800 The uuid library is now more paranoid about assuming the correctness
5801 of the /dev/random device; it mixes in a stream of bytes from
5802 random/srandom, just in case.
5804 Update Debian files to reflect the fact that I am now the Debian
5805 maintainer of e2fsprogs. Other various Debian-specific packaging
5808 Move the source tarball generation functions from the top-level
5809 makefile to the util/gen-tarball script.
5811 Updated the Turkish .po translation file.
5813 Added Heimdal and MIT krb5 extensions to the com_err library to make
5814 it more compatible with com_err libraries from those distributions.
5816 Changed dumpe2fs to always display the superblock fields relating to
5817 the journalling and/or directory indexing feature even if those
5818 features are not enabled.
5820 Updated and clarify copyright statement vis-a-vis alpha releases of
5823 The ss library will now try to dynamically link to the readline
5824 library and use it if it is present in the system. This means that
5825 the debugfs program now has line editing and history features. The
5826 SS_READLINE_PATH environment variable is used to find a readline or
5827 readline-compatible library.
5829 E2fsck now finds most duplicate filenames (all when rebuilding all
5830 directories via the -D option) and offers to delete or rename
5831 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
5833 Fix bug in e2image. When writing out a raw image file, include data
5834 blocks from symlinks that do not store the symlink within the inode.
5836 Fix bug in resize2fs which incorrectly moved the block and inode
5837 bitmaps for sparse superblock filesystems and incorrectly marked
5838 blocks as in use. (Addresses Debian bug #174766)
5840 Added a new shared library, the blkid library, which efficiently
5841 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
5842 and UUID filesystem specifiers without needing to search all of the
5843 devices in the system. Instead, the device is looked up in a cache
5844 file, and then verified to make sure the blkid cache is correct.
5846 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
5847 the device name, using the blkid library. (Addresses Debian bugs
5850 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
5851 used for spaces in device labels.
5853 Removed 32-bit limitations for debugfs's dump command.
5855 If the user specifies a large number of inodes, Mke2fs will
5856 automatically adjust the number of blocks per group to find a valid
5857 set of filesystem parameters.
5859 Add workaround to detect broken MD devices where when some of the
5860 underlying devices are marked read-only, writes to the MD device are
5861 silently dropped. E2fsck will detect if there is an attempt to run
5862 the journal twice, and abort with an error if this is the case.
5863 (Addresses IBM Bugzilla bug #1226)
5865 E2fsck will print an error if more than one of the -p/-a, -n or -y
5866 options are specified.
5868 E2fsck will fix HTREE corruptions in preen mode, without stopping the
5869 boot process. This is needed because the 2.4 ext2 filesystem
5870 accidentally had the INDEX_FL backwards compatibility code removed.
5872 Mke2fs no longer creates filesystems with the dir_index flag set by
5873 default; the user has to specifically request it.
5875 Update and clarified various man pages. (Addresses Debian bugs
5876 #173612, #175233, #175113, and #170497, #185945, #188318)
5878 Created man page for the mk_cmds program (from the libss library).
5883 Fix various gcc -Wall nits.
5885 Fixed a lot of portability problems that caused e2fsprogs not to build
5886 successfully under Solaris and Apple/Darwin.
5888 Fixed a Makefile dependency to allow building e2fsprogs using parallel
5891 Changes to create a subset distribution which consists only of the
5892 et, ss, uuid, and blkid libraries. The configure script and top-level
5893 makefile were changed to support working with a subset distribution.
5895 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
5896 actually used, and might people who are looking for
5897 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
5899 Updated debian files to fix a number of Lintian warnings.
5901 Updated config.guess and config.sub with newer versions from the FSF.
5903 Removed unnecessary libraries from being linked into the fsck, lsattr,
5904 chattr, and blkid executables.
5906 E2fsprogs 1.32 (Nomvember 9, 2002)
5907 ==================================
5909 Fixed a bug in the Unix I/O routines which caused needless writebacks
5910 of clean blocks from the unix_io cache (they were erroneously marked
5911 as being dirty, so they were getting written back to disk before
5912 getting evicted from the disk cache). This was harmless, but it
5913 significantly slowed down e2fsck.
5915 Made some other minor optimizations to the Unix I/O routines to save a
5916 small amount of CPU time.
5918 Updated internationalization files.
5921 E2fsprogs 1.31 (Nomvember 8, 2002)
5922 ==================================
5924 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
5925 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
5926 handling for child process that die unexpectly. Add a hack to force
5927 mkfs to create filesystems that won't cause problems with hardware
5928 that has 2k or 4k minimum blocksize requirements. Read from child
5929 processes in non-blocking mode, so that the GUI continues to update.
5931 Fix e2fsck so that it returns the appropriate exit code when the root
5932 filesystem has been changed, so that system's rc scripts will be told that
5933 the system needs to be rebooted.
5935 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
5936 was set, some of the descriptor blocks that should have been written
5937 out were getting skipped.
5939 Changed e2fsck to force out changes to the backup copies of the
5940 superblock and block group descriptors when important changes are made
5941 to those data structures.
5943 Fix a bug where e2fsck could erroneously mark a filesystem as being
5944 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
5945 introduced in e2fsprogs 1.28.)
5947 If journal debuging is enabled using --enable-jbd-debug, the debugging
5948 level is now set via the E2FSCK_JBD_DEBUG environment variable.
5950 If byteswapping support is disabled using configure --disable-swapfs,
5951 skip the tests which depend on byte-swapping, so that "make check"
5954 Lshattr will now display the indexed directory flag. Also, some of
5955 the more esoteric compression flags are supressed unless compression
5956 support has been enabled.
5961 E2fsprogs 1.30 (October 31, 2002)
5962 =================================
5964 When resizing a filesystem, and inodes need to moved, resize2fs will
5965 update the inode's ctime field, and the mtime field of the containing
5966 directories, so that incremental backups using dump/restore will work
5969 In order to avoid spurious errors, e2fsck wil check the last
5970 superblock write time to determine whether or not it can safely use
5971 the LOW_DTIME checks to determine if there are inodes on the orphan
5972 inode linked list that had somehow gotten disconnected. (Addresses
5973 Sourceforge bug #620980)
5975 Partition in /proc/partitions that being with the string "lvm" are
5976 considered real partitions even if they do not end with a number.
5978 Fixed a bug in the the uuid generation function, where if /dev/urandom
5979 is not present, but /dev/random is, and there isn't sufficient
5980 entropy, the get_random_byte function could spin a loop forever.
5982 E2fsck, mke2fs, etc. will now reliably notice when image files are
5983 mounted using the loopback interface. (Addresses Sourceforge bug
5986 When flushing buffers (as is done by badblocks, for example) check to
5987 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
5988 FDFLUSH ioctl which causes the MD device driver which causes confusing
5989 syslog messages about obselete ioctl messages. (Addresses Sourceforge
5992 Debugfs's write command now checks to see if the destination filename
5993 exists before creating it. (Addresses Sourceforge bug #478195.)
5995 When installing man pages, search for compressed man pages using all
5996 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
5998 Fixed a bug in fsck where multiple filesystems specified on the
5999 command were not being checked in parallel due to a logic bug
6000 introduced to support the FSCK_MAX_INST environment variable.
6002 We have added a new superblock field, s_mkfs_time, which indicates
6003 when a filesystem was created. It is set via mke2fs, and printed out
6004 by dumpe2fs, but is not actually touched by the kernel.
6006 Dumpe2fs has been made more robust by not aborting if there is an
6007 error reading the block/inode bitmaps; instead it will still print out
6008 the location of the block/inode bitmaps and inode table.
6010 Add support for the an alternative block group descriptor layout which
6011 allows for on-line resizing without needing to prepare the filesystem
6012 in advance. (This is the incomat feature flag meta_bg.)
6014 Add support for storing default mount options in the superblock, so
6015 that the filesystem can be mounted with specific mount options without
6016 needing to specify them on the mount command line or in the /etc/fstab
6019 Add support for a new inode flag, which is to be used for indicating
6020 the top of directory hierarchies for the Orlov block allocator.
6022 Fix e2fsck so that if it creates the lost+found directory, it does so
6023 with the more apporpriate permissions of 0700. Also change
6024 mklost+found so that it also creates the directory 0700.
6026 Fixed format bug in e2fsck if NLS is in use.
6028 Add a German translation for e2fsprogs's NLS support.
6030 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
6031 the beginning of the inode table. This won't matter much, since if
6032 there is a bad block at the beginning of the inode table, the root
6033 directory won't be available. But at least e2fsck won't crash in this
6036 Fixed endian problems in the htree code for e2fsck and debugfs.
6038 When byte-swapping a filesystem on a PPC architecture, byte-swap the
6039 bitmaps since the historical big-endian ext2 variant had byte-swapped
6040 bitmaps, and the ext2fs library assumes this. This fixes the
6041 regression test suite on PPC machines.
6043 Fix e2image so that it handles a bad block in the inode table
6046 E2fsck now uses a more sophisticated algorithm to salvage corrupted
6047 directories that recovers more information in the corrupted directory
6050 E2fsck now performs additional consistency checks on indexed (HTREE)
6053 Fix bug where efsck might get confused about whether a completely
6054 empty directory block is an empty leaf block or an interior htree
6055 node. This could cause e2fsck to get confused into think that a valid
6056 indexed directory was corrupted.
6058 E2fsck no longer creates an empty directory entry at the end of a
6059 directory block when optimizing a directory. This would cause some
6060 earlier versions of the dxdir kernel code to corrupt the directory
6061 when attempting to split a node containing an empty directory entry.
6063 E2fsck could sometimes in rare circumstances leave the indexed flag
6064 set after a small directory was optimized by compressing it instead of
6065 indexing it. (This should never happen in real life, since
6066 directories that small wouldn't have been indexed, but better safe
6069 E2fsck now only updates the master superblock in all cases. This
6070 slightly shortens its run time.
6072 Ext2ed can deal with directory entries of length 0; previously it
6073 would get stuck in an infinite loop.
6075 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
6076 specifiers. (Sourceforge patch #613447)
6078 Badblocks will now work correctly on read-only devices such as
6079 CD-ROM's. (Sourceforge patch #600451)
6081 Updated and clarified man pages. (Addresses Debian bug #167108)
6084 E2fsprogs 1.29 (September 24, 2002)
6085 ===================================
6087 Fixed a bug in e2fsck which could corrupt a directory when optimizing
6088 it (via the -D option) or rebuiliding the hash tree index with a 1 in
6089 512 probability, due to a fence post error.
6091 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
6094 Mke2fs now enables the directory indexing flag by default. (Since
6095 this is a compatible feature flag, it's safe to do so.)
6097 Tune2fs will support setting the directory indexing feature flag. It
6098 will automatically set up the default hash algorithm and hash seed
6099 fields in the superblock.
6101 If the bone-headed user enters the root filesystem twice in
6102 /etc/fstab, the -R option which skips the root filesystem will skip
6103 all of them. (Addresses Debian bug #159423). Note! This is not a
6104 precedent for dealing intelligently with any other kind of doubled
6105 entry in /etc/fstab!
6111 Removed perror declaration in lib/et/internal.h. All modern systems
6112 can be expected to define perror() these days. Besides, the lib/et
6113 code wasn't using perror at all anyway. :-)
6116 E2fsprogs 1.28 (August 31, 2002)
6117 ================================
6119 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
6120 for setting the htree flag is not included yet, although it can be
6121 manually turned on via the debugfs program.
6123 Clarified e2fsck error message which is printed when it cannot find
6124 sufficient contiguous block when relcating filesystem metadata.
6126 Added support for building an EVMS plugin module for ext2/3. This
6127 module is substantially the same as the EVMS module shipping with EVMS
6128 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
6129 for use with EVMS 1.0 (which did not include the ext2 plugin module),
6130 if the configure --enable-old-evms flag is given.
6132 Fsck will search through EVMS volumes when trying to resolve
6133 filesystem specifications such as LABEL=xxx or UUID=xxx.
6135 Added a new utility program, /sbin/findfs, which will return
6136 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
6139 Update and clarified various man pages. (addresses Debian Bug #145044,
6140 #146437, #131350, #151990, #144621, #141938)
6142 If there are no filesystems specified on fsck's command line, fsck now
6143 treat that as if the -As options were given. Previously it would
6144 simply do nothing. (Addresses Debian Bug #153102)
6146 Mke2fs no longer treats a failure to be able to clear the MD signature
6147 at the end of the filesystem as a fatal error. (Addresses Debian Bug
6150 The e2p library functions (which are used by lsattr and chattr) now
6151 double check to make sure the file is a regular file or directory
6152 before attempting to use the ext2 ioctls. Some device drivers
6153 unfortunately respond to the ext2 ioctl's with unknown behaviour.
6154 (Addresses Debian Bug #152029).
6156 The extended attribute handling has been updated to correspond with
6157 the latest V2 bestbits ACL code.
6159 Fixed bug in e2fsck which caused it to not clear the dtime field when
6160 processing truncated inodes on the orphan list. This could cause data
6161 loss(!) if a filesystem is rebooted before a truncate has been
6164 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
6165 algorithms. This makes e2fsck much faster in the case of severely
6166 corrupted filesystems where a large number of blocks are claimed by a
6167 large number of inodes. (Thanks to the 2.5 IDE device driver for
6168 inspiring this work.)
6170 Resize2fs has been significantly sped up when shrinking and expanding
6171 a filesystem by a very small number of blocks (for example, when EVMS
6172 is converting a partition to be an EVMS legacy volume).
6174 Added a new option to e2fsck, -D, which will optimize or compress all
6175 of the directories in the filesystem.
6177 E2fsck now catches SIGINT and SIGTERM to make sure it will can
6178 properly clean up and only exit at safe points. Fsck will pass
6179 SIGINT/SIGTERM to its child processes, and wait until they have all
6180 exited before it exits.
6182 The uuid parsing code in the uuid library now properly complains when
6183 an illegally formated uuid is presented to it. (Addresses Debian bug
6186 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
6187 and 2.4.17, since the workaround can cause problems when using a 2.4
6188 kernel with an old version of glibc built with the 2.2 headers.
6190 Fixed a bug in mke2fs where it wasn't properly clearing the initial
6191 superblock used by other filesystems. (Addresses Debian bug #147256.)
6193 Added support for the synchronous directory feature written by Andrew
6196 The debugfs program can delete directories using the rmdir command.
6198 Add support for 8k and 16k filesystems (for systems with page sizes
6199 that are greater or equal to 8k or 16k, respectively). Note that
6200 these filesystems can not be mounted on x86 systems, or other systems
6201 with only 4k page sizes, due to limitations in the current Linux VM
6204 Resize2fs requires that the filesystem state be valid and have no
6205 errors; otherwise, e2fsck -f must be run first. (Previously it simply
6206 required that the last fsck time be greater than the last mount time.)
6208 Configure now defaults the man pages directory to /usr/share/man on
6211 E2fsck now offers to truncate inodes which contain too many blocks (so
6212 that i_blocks would overflow. Also fixed handling of large sparse
6215 E2fsck now more completely checks for symlink validity, including
6216 requiring NULL termination and length checks.
6218 E2fsck will offer to try forcing a disk write to remap a bad block
6219 after finding a read error when reading a filesystem metadata block.
6221 Fixed a bug in debugfs which caused the -b and -s options to crash
6222 debugfs, as well as breaking the testb, setb, and clearb functions.
6224 Added a bmap command to debugfs which calculates the logical to
6225 physical block mapping for a particular inode.
6227 Fixed a bug in code which checked to see if a device was mounted which
6228 sometimes (rarely) failed in the case of a plain file.
6230 Fixed a bug in resize2fs where when it reported an error, it would
6231 print a message erroneously indicating that the filesystem had been
6232 resized before it aborted.
6234 When resizing a plain file which is smaller than the requested size,
6235 resize2fs will attempt to extended the file so that programs like
6236 e2fsck will not complain that the file is too small.
6238 Resize2fs will print the actual new size of the filesystem when it is
6241 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
6242 information on big-endian systems.
6248 Fixed collisions with C++ reserved words.
6250 Added portability fixes for building e2fsprogs on the HURD and AIX.
6252 Added the ext2ed program for creation of test cases. (ext2ed has many
6253 limitations and bugs which make it unsuitable for production use.)
6255 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
6256 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
6257 name_len field is byte swampped on big-endian machines, since in the
6258 V2 structure, name_len is a char field which is doesn't need to be
6259 byte swapped --- except if an old-style kernel had byte-swapped the
6260 name_len field as part of the V1 structure.
6263 E2fsprogs 1.27 (March 8, 2002)
6264 ==============================
6266 The warning messages for mke2fs now go to standard error.
6268 Fixed to make sure "make check" runs all of the test programs with
6269 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
6271 The mke2fs program checks the boot sector for the BSD disk label, and
6272 avoids erasing it if it is there.
6274 Fixed a bug in e2fsck which caused it to core dump if the journal
6275 inode was missing when it was supposed to be there.
6277 E2fsck now prints ranges in pass 5 when printing deltas for the block
6280 Debugfs's "ls -l" command now will print out the file type information
6281 in the directory entry.
6283 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
6284 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
6286 Debugfs can now examine the experimental directory indexing
6289 Fixed bug in debugfs which caused it to core dump if modify_inode is
6290 called without an open filesystem.
6292 The debugfs lsdel command now runs its output through a pager first.
6294 When installing manual pages, remove the compressed manual pages first.
6296 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
6298 Fix the 2.4 resource limitation workaround introduced in 1.26 which
6299 actually broke things on mips32, sparc32, and Alpha platforms.
6301 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
6302 (which is required by the newer libintl libraries).
6307 Fixed various gcc -Wall complaints.
6309 Fixed a few memory leaks in the e2fsck journaling code, and in the
6310 ismounted code checking for a swap device.
6312 Add new inode I/O abstraction interface which exports an inode as
6315 Exported ext2_file_flush as a public interface.
6317 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
6319 Lots of small random portability fixes to make e2fsprogs build under
6320 AIX --- even without the 5L compatibility toolkit, and even using the
6321 uber-crippled AIX native C compiler.
6324 E2fsprogs 1.26 (February 3, 2002)
6325 =================================
6327 Dumpe2fs will keep going now if the bad block inode can't be read.
6328 (Previously it stopped with a fatal error.)
6330 E2fsck will now give an opportunity to run the journal even if the
6331 recovery flag is not set. This is the default behaviour if e2fsck is
6332 using a backup superblock, since the needs_recovery flag will never be
6333 set in the backup superblock copies.
6335 E2fsck now automatically finds the backup superblock/group descriptors
6336 even when the primary superblock is completely destroyed for 2k and 4k
6337 filesystems. (Previously it just guessed/assumed that we were dealing
6338 with a 1k filesystem in that case, and users had to manually specify
6339 the backup superblock number.)
6341 Fixed a bug in e2fsck where it dereferences a null pointer when there
6342 is a problem opening a filesystem in preen mode.
6344 E2fsck now handles external journals correctly; previously it trashed
6345 the external journal device if the journal needed to be replayed.
6347 Work around ulimit incompatibility problem caused by recent 2.4
6348 kernels; the unix IO module will automatically try to set any resource
6349 limits to be infinite on startup.
6351 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
6352 bitmap if it wasn't present and the blocksize was 2k or 4k.
6353 (Addresses Debian Bug #116975)
6355 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
6356 clearing the new V2 fields if they do not make sense or if the ext3
6357 superblock is version 1 superblock.
6359 E2fsck will automatically relocate the ext3 journal from a visible
6360 file (i.e., /.journal) to an hidden inode if the filesystem has been
6361 opened read/write. This allows the users to add a journal while the
6362 filesystem is mounted, but the next time the system is rebooted, the
6363 journal file will disappear. This avoids problems with backups,
6364 stupid operators with superuser bits, etc.
6366 Fix a bug in fsck where it would not support a filesystem type of
6367 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
6369 Fsck now supports fstab entries of the form "ext3,ext2". It will also
6370 automatically identify reiserfs filesystems.
6372 The number of processes spawned by fsck can now be limited using the
6373 FSCK_MAX_INST environment variable.
6375 Fsck now searchs the LVM proc hierarchy to find logical volumes which
6376 should be searched for UUID and label information.
6378 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
6379 limit if at all possible, when opening a block device. (The filesize
6380 limit shouldn't be applied against writes to a block device.)
6382 In mke2fs and e2fsck, specifying the -c option twice will now do
6383 a read/write test on the disk. Update the man pages to encourage
6384 using the -c option, and to discouraging running badblocks separately,
6385 since users tend to forget to set the blocksize when running
6388 Mke2fs now automatically clears the immutable attribute on a
6389 pre-existing .journal file left over from a previous failed attempt to
6390 add a journal to an alreadyy-mounted filesystem.
6392 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
6395 Mke2fs now creates the lost+found directory with permissions of 0700,
6396 so that files that had previously lived in protected directory are
6397 safe if they get dropped in lost+found and the system administrator
6398 doesn't deal with immediately. (Addresses Debian #bug 118443)
6400 Mke2fs and e2fsck (and all programs that use the
6401 ext2fs_check_if_mounted function) will now properly identify that a
6402 device is mounted, even in cases where devfs has confused things with
6403 multiple devices names with the same identity, or if a dim-witted
6404 system administrator has done something stupid like creating device
6405 file aliases in their home directory. Also now checks for swap devices
6406 by using /proc/swaps. (Addresses Debian bug #106622)
6408 Added a new option (-T) to tune2fs which sets the time a filesystem
6411 Speed up e2image when creating sparse raw image files by optimizing
6412 away excess lseek() system calls.
6414 Fix support of large (> 2GB) files when used as a filesystem in
6415 mke2fs, tune2fs, debugfs, and findsuper.
6417 Debugfs's stat and icheck commands now properly deals with large (>
6420 Debugfs's set_super_value command now prints out the list of valid
6421 superblock fields which can be set using the command.
6423 Debugfs's rm and kill_file command now updates the superblock free block
6424 and inode counts, thus keeping the filesystem consistent.
6426 Debugfs's lsdel command now takes an optional argument which allows
6427 the user to only see the most recently deleted files.
6429 A new command (undel) was added to debugfs which automates
6430 undeleting a deleted inode and linking it back to a directory.
6432 Debugfs's ls command now takes a new option, -d, which lists
6433 deleted directory entries.
6435 Debugfs's testb, freeb, setb, and find_free_block commands now take an
6436 optional count argument.
6438 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
6439 be used to signal that a particular inode should not be eligible for
6440 tail-merging --- this is needed for programs like LILO.
6442 The findsuper (an unreleased, uninstalled utility program) has been
6443 improved to add extra validity checks and to add a progress meter.
6444 (It is still an unsupported program; the officially supported way to
6445 recover from a trashed partition table is to use gpart; findsuper is
6446 for wizards only. :-)
6448 Debugfs was fixed to compile with "configure --disable-swapfs".
6450 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
6452 Added new translation file for Turkish.
6457 Fix general gcc -Wall complaints.
6459 E2fsprogs (mostly) works with the dietlibc.
6461 The programming texinfo file has been expanded to include description
6462 of additional libext2fs functions. (Still not compeltely done, but a
6463 lot of the more important functions have been documented.)
6465 Added a umask structure to struct_ext2_filsys, which currently only
6466 modifies the behaviour of ext2fs_mkdir(), but if we add any file
6467 creation functions to libext2fs, we should also make sure they respect
6470 The build-rpm script was fixed to be a bit more safe.
6472 The tests' Makefile now has a way of automating test case creation
6473 for e2fsck, using "make testnew".
6475 Created a new function, ext2fs_dir_iterate2 which passes more
6476 information to the callback function (identical to the one used by
6477 ext2fs_dblist_dir_iterate). The directory iterator functions take a
6478 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
6479 directory entries. If the directory entry is deleted, the callback
6480 function will be called with the entry paraemter set to
6481 DIRENT_DELETED_FILE.
6483 Added new functions, ext2fs_inode_alloc_stats and
6484 ext2fs_block_alloc_stats, which takes updates block/inode allocation
6485 statistics in the bitmaps, block group descriptors, and superblock
6486 when inodes or blocks are allocated or deallocated.
6489 E2fsprogs 1.25 (September 20, 2001)
6490 ===================================
6492 This is primarily a bug-fix release; no new features were added, but
6493 there are a number of embarassing bug fixes and cleanups applied.
6495 Fix a bug mke2fs which causes stack garbage to be written to disk when
6496 zapping disk sectors. (This bug could cause mke2fs to core dump for
6497 some kernels, I suspect with security enhancement patches.)
6499 Remove unneeded #include of <linux/config.h> which was breaking
6500 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
6502 Updated tune2fs man page to reflect the fact that adding or removing a
6503 journal doesn't require running e2fsck.
6505 Remove use of AC_REQUIRE from autoconf which had been used to prevent
6506 AC_CANONICAL_HOST from being called twice; unfortunately this causes
6507 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
6508 used outside of autoconf macros. Fortunately, it doesn't seem to be
6509 necessary any more, anyway.
6511 E2fsck will now not fall back to an alternate superblock if the user
6512 specifies the superblock location explicitly on the command-line.
6513 This allows easier recovery from a situation where the primary
6514 superblock and block groups are slightly corrupted, but the backup
6515 superblocks are completely broken.
6517 Fix problem which caused compile_et and mk_cmds to blow up if
6518 e2fsprogs was in a directory with a pathname that contained spaces.
6520 We are now more paranoid about checking the entry in /etc/mtab to make
6521 sure the filesystem is really mounted, since some broken distributions
6522 (read: Slackware) don't initialize /etc/mtab before checking non-root
6523 filesystems. (Slackware also doesn't check the root filesystem
6524 separately, and reboot if the root filesystem had changes applied to
6525 it, which is dangerous and broken, but there's nothing I can do about
6528 Make UUID library C++ friendly by adding appropriate extern "C"
6529 declarations and using const in the function declarations.
6531 Fix up the com_err texinfo file so that it can product a valid info
6532 file (previously, it could only be used to generate paper
6533 documentation using texinfo.tex).
6536 E2fsprogs 1.24a (September 2, 2001)
6537 ===================================
6539 Fix brown-paper bug in mke2fs which caused it to segfault when
6540 printing the version string.
6543 E2fsprogs 1.24 (August 30, 2001)
6544 ================================
6546 Revert the BLKGETSIZE64 support, since for some distributions, this
6547 ioctl has been used by an unofficial kernel patch to update the last
6548 sector on the disk, and this was causing disk corruption problems as a
6551 Mke2fs is now more careful about zapping swap space signatures and
6552 other filesystem/raid superblock magic values so that programs like
6553 mount who try to use hueristics to determine the filesystem type of a
6554 partition are less likely to be confused.
6556 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
6557 regular file (since Andreas Dilger's on-line resizing tools will set
6560 Fixed some minor texinfo, man pages nits for spelling errors,
6561 texinfo warnings, etc. (Addresses Debian bug #110621.)
6563 E2fsprogs program no longer print the filesystem version number
6564 (i.e. 0.5b), since it only confuses people and doesn't serve any real
6567 E2fsck will once again compile under libc5, since it will supply its
6568 own version of strnlen if necesssary.
6570 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
6571 when specifying the external journal device. tune2fs will also search
6572 devices looking for the externla journal debice when removing.
6574 E2fsprogs 1.23 (August 15, 2001)
6575 ================================
6577 Add initial support for extended attributes (EA); e2fsck will
6578 correctly handle a filesystem with EA's and check the EA blocks for
6581 E2fsck's symlink sanity checking has been cleaned up. It now checks
6582 the i_size value of fast symlinks, and checks for immutable flags
6583 being set of symlinks, etc.
6585 E2fsck now offers to clear inodes which are special files that have a
6586 non-zero i_blocks or i_size field. (The i_size field check was in the
6587 previous version of the code, but due to a bug it didn't offer to
6588 clear the inode unless i_size and i_size_high were both non-zero.)
6590 E2image can now create "raw" image files, which only contain the
6591 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
6592 debugfs, etc., can be run directly on the raw image file.
6594 Add support for the 64-bit block device patches.
6596 Fixed bugs in creating external journals with a 1k blocksize.
6598 Add initial support for external journals (so long as the external
6599 journal only supports a single filesystem) in e2fsck.
6601 Remove requirement for needing to run fsck on a filesystem after
6602 removing a journal (either internal or external).
6604 The man pages now document how to create and manage external journals.
6606 Speed up the check of an ext3 filesystems by avoiding a needless flush
6607 of all of the superblock and block group descriptors.
6609 Speed up creating an internal journal using tune2fs in the case where
6610 the filesystem has a lot blocks already allocated.
6612 Tune2fs has been fixed to make sure that only error messages go to
6613 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
6615 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
6616 now not set the sparse_super feature. (Addresses Debian bug #108165)
6618 Add support in fsck for the filesystem type "auto".
6620 Fsck -A will not try to interpret device names for filesystems which
6621 have a pass number is 0. (Addresses Debian bug #106696).
6623 Fsck prints a warning message if now valid filesystems are passed to
6624 it. (Addresses Debian Bug #107458.)
6626 E2fsck now gives an explicit warning if there filesystem still has
6627 errors at the end of the run. (Addresses Debian bug #104502)
6629 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
6630 reflects an error. E2fsck will also not run the orphan list if the
6631 filesystem contains errors, since the orphan list might be corrupted.
6633 E2fsck now prints the number of large files when given the -v option.
6635 Fixed minor memory leaks in e2fsck.
6637 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
6640 E2fsprogs 1.22 (June 22, 2001)
6641 ==============================
6643 Fixed a bug in e2fsck's handling of orphan inodes which are special
6644 files (i.e., block/character device files, named FIFO's, etc.).
6646 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
6647 tune2fs to fail at adding a journal to a mounted filesystem.
6649 Fixed a few big-endian bugs in e2fsprogs
6650 * The directory block functions were accidentally reporting
6651 some directories as corrupted when they weren't.
6652 * If e2fsprogs is compiled --disable-swapfs, the C language
6653 equivalents weren't being included for big-endian platforms.
6654 (Fixes Debian bug #101686).
6656 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
6661 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
6662 ioctls, and allow them to be defined for non-i386 platforms.
6664 The uuid.h header file is now protected against multiple inclusions.
6666 E2fsprogs is now being developed using BitKeeper. Changed the test
6667 scripts to deal with BK's stripping CR characgters from text files,
6668 and changed the top-level Makefile.in to avoid including BitKeeper
6669 files when generating the source tarball.
6672 E2fsprogs 1.21 (June 15, 2001)
6673 ==============================
6675 Added new configure flags which allow a subset e2fsprogs to be built;
6676 this is most useful for boot floopies, since the resulting shared
6677 libraries and programs are slimmed down by removing features that
6678 aren't necessary for a boot floppy. The new flags that were added
6679 are: --disable-swapfs, which removes support for byte swapping old
6680 legacy PPC/68k filesystems, --disable-debugfs, which removes support
6681 for debugfs from the libext2fs library, --disable-imager, which
6682 removes support for the e2image program, and --disable-resizer, which
6683 removes support for resize2fs.
6685 E2fsck now prints the number of mounts or days elapsed since the last
6686 check when e2fsck is forced to check an otherwise clean filesystem.
6688 Tune2fs now prints an informative message about how often a filesystem
6689 will be checked when adding a journal to the filesystem, to remind the
6690 user that he/she may want to adjust those parameters using tune2fs
6693 Worked around hurd brain-damage which causes e2fsck to sometimes
6694 believe a filesystem is the root filesystem based on device numbers
6695 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
6698 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
6699 erroneous error with the -F option was specified.
6701 Fixed a ext3 recovery bug in the revoke handling; synchronized with
6704 Fixed two bugs in e2fsck's handling of dup block handling, dealing
6705 with relatively uncommon edge cases: a directory with an indirect
6706 block which is claimed by another file, and when the last inode in the
6707 filesystem has blocks claimed by another file.
6709 E2fsck now checks to see if the i_size field of a fast symlink is too
6710 big, and offers to clear the symlink if so.
6712 E2fsck now checks to see if i_size_high of special files is non-zero,
6713 and offers to clear i_size_high.
6715 Fix e2fsck's handling of incompatible journal flags so that the user
6716 has chance to abort, and then has the option to clear out the journal
6717 entirely. (Addresses Debian bug #98527.)
6719 Fixed a bug in fsck which could cause it to core dump if a mix of
6720 standard and non-standard device names are used in /etc/fstab.
6721 (Debian bug #100559)
6723 Fixed a bug in debugfs which caused read errors when copying a file to
6726 The debugfs set_super_value command can now modify the s_lastcheck field.
6728 Fixed a bug in lsattr and chattr which was accidentally introduced in
6729 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
6730 directories correctly because the change modified the layout of struct
6731 dirent to be incompatible with the libe2p shared library.
6733 Cleaned up the mke2fs manual page and included a discussion about why
6734 it's good to periodically check the filesystem even when journaling is
6740 Fix general gcc -Wall complaints.
6742 The types needed by the ext2 header files are now provided by
6743 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
6745 Integers are now preferred to longs when trying to find a 32-bit type
6746 in ext2_types.h. Also, if linux/types.h has already been defined,
6747 don't try to redefine the types.
6749 Fixed make depend script so that it automatically corrects the
6750 pathname cleanups performed by make -M, so I don't have to fix them up
6753 Fixed the d_loaddump test case to be more robust, and not depend on
6756 Removed debugfs's dependence on pread(), which was accidentally
6757 intrudced in e2fsprogs 1.20
6759 Fixed a performance bug in the libext2fs's icount routine; the size
6760 estimate of the icount array was incorrectly being calculated.
6762 Removed use of the badblocks compatibility functions in the e2fsprogs
6765 Added paranoia code which protects against strange cases where /etc
6766 isn't on the root filesystem, or if /etc/mtab doesn't exist.
6768 The header file ext2_types.h is now installed.
6770 Autoconf is used to determine when we are on big-endian machines,
6771 instead of doing run-time tests, to save a few bytes of code.
6773 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
6774 functions are no longer inline functions, which saves space and
6775 doesn't really cost any real performance.
6777 The ext2fs library no longer depends on the e2p library. (What need
6778 there was of it --- namely, fsetflags, was coded in-line).
6780 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
6781 when the user is stupid and tries compiling the package using "make
6784 Miscellaneous code cleanups:
6785 * Added missing files from Makefile.in's SRCS file, so that
6786 their dependencies would be properly calculated.
6787 * Removed redundant code
6788 * Fixed comments in code
6789 * Removed no-longer unneeded argsused #pragma.
6792 E2fsprogs 1.20 (May 20, 2001)
6793 =============================
6795 Add support for replaying the ext3 journal purely in user mode,
6796 including handling the orphaned inode list. Used code contributed by
6797 Andreas Dilger, with bug fixes and the orphaned inode handling done
6800 The mke2fs and tune2fs programs can create or modify a filesystem to
6801 include an ext3 journal. Tune2fs also can be used to remove an ext3
6802 journal from a filesystem.
6804 E2fsck will now check for the existence of a linked list of orphan
6805 inodes in the superblock, and clear those inodes before starting the
6806 rest of the filesystem check (but after the journal playback).
6808 E2fsck now validates the file descriptor passed to the -C option,
6809 which saves against the completion bar getting written to an
6810 unexpected location, such as the disk being checked. (Debian
6811 bug/wishlist #55220)
6813 E2fsck will now bump the filesystem revision number from zero to one
6814 if any of the compatibility bits are set.
6816 Fixed a bug where a badly corrupted directory on a big endian system
6817 could cause e2fsck to die with a bus error. The
6818 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
6819 the ext2 library now does alignment sanity checks on the rec_len field
6820 of the directory entry before using it.
6822 The ext2 library has been enhanced to make tune2fs safe to run on
6823 mounted filesystems. (Users could usually get away with using tune2fs
6824 on mounted filesystems before, but with the advent of ext3 and
6825 journaling, it became important to make tune2fs was *really* safe for
6826 use even when the filesystem being modified is mounted.) E2label is
6827 now implemented by tune2fs using an argv[0] dispatch, so that e2label
6828 is also now safe for use on mounted filesystems.
6830 Added a new program, e2image, which creates a backup of critical ext2
6831 filesystem data structures. The generated image file can be examined
6832 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
6833 the image file to help recover very badly damaged filesystems.
6835 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
6836 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
6837 large file when deciding whether or not the filesystem has large files.
6839 Fixed lsattr and chattr so that they work correctly on large files.
6840 (Fixes Debian bug #72690.)
6842 Removed limitation in get_device_size() which imposed a one terrabyte
6843 filesystem limitation. (Most 2.2 kernels still have a signed int
6844 problem which cause 1 TB block device limitation. Fortunately, the
6845 kernel patches to fix this are much easier than fixing the 2TB
6846 limitation in the kernel. :-)
6848 A max_mount_count of zero is now treated as if no mount count were
6849 set. (Previously, no mount count was indicated by using -1, and a
6850 mount count of zero caused e2fsck to always be run.)
6852 Mke2fs supports two new filesystem types largefile and largefile4.
6854 Mke2fs now adds some randomness in s_max_mount_count so that multiple
6855 filesystems won't be all checked at the same time under normal
6858 Fixed bug in the progress bar printing code which could cause e2fsck
6859 to core dump on an illegal filesystem.
6861 Fixed bug in fsck which could allow more than one instance of e2fsck
6862 to be printing a progress bar. (Debian bug #65267)
6864 Fsck using a UUID or a LABEL specifier will work even if devfs is
6865 compiled into the kernel and not mounted. If the pathnames in
6866 /proc/partitions are incorrect, fsck will search /dev for the correct
6867 device (using the new ext2fs_find_block_device library function).
6868 Fsck now also checks the RAID devices first so that they are properly
6869 found when they are in use. Support has also been added to support
6870 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
6872 Fixed a bug in fsck which caused it not deal properly with 16
6873 byte long filesystem labels.
6875 Fsck's -t option has been made a lot more flexible. The semantics for
6876 what happens if a comma-separated list to fsck has been regularized,
6877 and it is now possible to filter what filesystems will get checked
6878 based what is in the filesystem's fstab entry's option field. (Debian
6881 The dumpe2fs program can now print out the group description
6882 information in hex, and also prints the location of the superblock and
6883 block group descriptor for those block groups that have them.
6885 Mke2fs now clears the ext2 superblock before it starts creating a
6886 filesystem, so that the superblock magic number is only written if the
6887 filesystem creation process successfully completes.
6889 The debugfs program's stat command now pretty-prints the blocks used
6890 by an inode so that it's more compact and informative.
6892 The debugfs stats command now uses the same libe2p code (which is used
6893 by dumpe2fs) to print the superblock header information. This is more
6894 complete, and it avoids a bit of code duplication.
6896 Added a new debugfs command, set_super_value (ssv) which allows the
6897 user to set arbitrary superblock fields.
6899 Debugfs was extended to support inode numbers in hex (by prefixing
6900 them with 0x), and so that modify_inode can set the inode generation
6901 number. Also, there is now a new function command called logdump
6902 which will dump an ext3 journal.
6904 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
6907 Debugfs's dump command now stops immediately upon reporting a disk
6908 read error. (Fixed a bug in ext2fs_file_read library routine which
6909 caused debugfs not to stop.) (Debian bug #79163)
6911 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
6912 checked before /etc/mtab is used, since /proc/mounts is more likely to
6915 Added portability fixes for Solaris and Linux/ia64.
6917 Various manual pages were clarified and cleaned up. (Fixed debian
6918 bugs #63442, #67446, and #87216)
6924 The e2fsck message printer now supports %Iu and %Ig, which will print
6925 out the inode's user and group owners, respectively.
6927 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
6928 that no longer dependent on the system having the correct version of
6929 the kernel header files.
6931 Added a new function to libext2, ext2fs_find_block_device(), which
6932 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
6933 device given its device number.
6935 Added a new function to libext2, ext2fs_sync_device, which centralizes
6936 all of the places which might try to use the BLKFLSBUF or FDFLUSH
6937 ioctls (and usually failing to define them since the system header
6938 files don't usually do this for us, and we're trying to avoid usage of
6939 kernel include files now).
6941 Added new utility programs in tests/progs: random_exercise and
6942 hold_inode. They aren't built by default; they're useful for
6943 exercising ext3 filesystem code.
6945 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
6946 the filesystem close functions to only update the superblock, and to
6947 not touch the block group descriptors. Needed by tune2fs when
6948 modifying a mounted filesystem.
6950 Got rid of struct ext2fs_sb and replaced it with the standard struct
6951 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
6952 source (but not binary) compatibility of some users of the ext2
6953 library. Those applications should just simply do a global search and
6954 replace of struct ext2fs_sb with struct ext2_super_block, and include
6955 the new header file <ext2fs/ext2_fs.h> which defines it.
6957 The ino_t type has been renamed ext2_ino_t to protect applications
6958 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
6959 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
6960 unexpected ABI change.
6962 The Makefiles have been reworked so that "make check" can be run from
6963 the top-level Makefile.
6965 Fix general gcc -Wall complaints and removed dead code.
6967 Remove use of NOARGS, because we assume everyone does ANSI C these
6970 Added build-rpm script from sct.
6972 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
6975 New function ext2fs_flush_icache which must be called if the
6976 application program modifies the inode table blocks without going
6977 through ext2fs_write_inode() interface.
6979 New ext2fs_check_mount_point() function, which will return the mount
6980 point of a device if mounted.
6982 The io_channel abstraction now has an optional interface,
6983 io_channel_write_range, which allows specific byte ranges to be
6986 The unix_io IO channel now supports write-through caching, so that
6987 journal creation is more efficient.
6989 Added x86 assembly language routines to support byte swapping, to
6990 reduce executable size.
6992 Fixed bug in the utility program subst so that it's possible to
6993 replace a substitution variable with a zero-length string.
6995 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
6996 slipped into some of the problem number.
6998 E2fsprogs 1.19 (July 13, 2000)
6999 ==============================
7001 Release the resize2fs program since the timeout before it could
7002 be released under the GPL has finally expired.
7004 Add experimental support needed for the ext2 compression patches.
7005 This requires compiling e2fsprogs with the --enable-compression flag
7006 to the configure script.
7008 Added ext3 journalling support. E2fsck will run the journal (if
7009 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
7010 installed as a symlink to e2fsck. Fsck has been taught about ext3,
7011 and treats it the same as ext2 in terms of the progress bar logic.
7012 Dumpe2fs will display the superblock journaling information if the
7013 filesystem has a journal. The ext2 library will now permit opening an
7014 ext3 filesystem with the recovery flag set. This is necessary for
7015 on-line dump's to work correctly, but there may be issues with this
7016 working well since ext3 is much less agressive about syncing blocks to
7017 the filesystem, since they're safe on the journal.
7019 Tune2fs and e2fsck have been changed to allow the mount_count check to
7020 be disabled by setting max_mount_count to -1. (This was already
7021 supported by the kernel.)
7023 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
7024 are used for ext3 as well.
7026 Added internationalization support for e2fsprogs; must be enabled
7027 by passing --enable-nls to configure.
7029 Always use the provided ext2fs header files to insulate ourselves from
7030 kernel version changes. Which include files are used by e2fsprogs
7031 have also been cleaned up to improve portability.
7033 Limit the number of times that e2fsck updates the progress bar so that
7034 people who are booting using a 9600 baud console don't get swampped by
7037 Improved the loop detection algorithm in e2sck's pass #3 so that it is
7038 much, much faster for large filesystems with a large number of
7041 The memory footprint for e2fsck is now slightly smaller than before.
7043 E2fsck now checks if special devices have a non-zero size, and offers
7044 to clear the size field if it finds such an inode.
7046 E2fsck now checks if special devices have the append-only flag set,
7047 and offers to clear the inode.
7049 E2fsck now properly handles some "should never fail" cases during a
7050 bitmap copy in pass5.
7052 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
7054 E2fsck now calculates the correct location of the backup superblock in
7055 the case of filesystem blocksizes > 1k.
7057 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
7058 which normally didn't cause problems under most filesystem parameters,
7059 but could cause a valid superblock to be rejected in extreme cases.
7060 Other checks for validating superblock values were made more
7063 Added non-destructive write testing to the badblocks program, courtesy
7064 of David Beattie. The badblocks also now has an option to input the
7065 current set of bad blocks, so that known bad blocks are skipped to
7066 speed up the badblocks test. There is also a persistent rescan
7067 feature which causes badblocks to run until it has completed some
7068 number of passes without discovering any new bad blocks.
7070 Badblocks now checks to see if the device is mounted and refuses to do
7071 the tests involving writing to the device if it is mounted. Also,
7072 badblocks now allows the number of blocks to be checked to be
7073 defaulted to the size of the partition.
7075 Fixed a bug in fsck which didn't allow non-root users to be able to
7076 check filesystems if there were any LABEL= or UUID= entries in
7079 The Hurd doesn't support the filetype filesystem feature. The mke2fs
7080 program now makes sure that for the Hurd, the filestype feature is
7081 turned off. E2fsck will check to see if the filetype feature is
7082 turned on for Hurd filesystems, and offer to turn off the feature.
7084 Mke2fs now has a safety check to make sure the number of blocks do not
7085 exceed 32 bits even on a 64 bit platform.
7087 Really fixed a bug in fsck to allow "fsck -As" to run interactive
7088 fsck's. (For those people who like to do interactive fsck's in the
7091 Debugfs has a few new features: the rdump command, which will do a
7092 recursive dump of a directory and all of its contents, and the lcd
7093 command which does a local chdir (much like the ftp command of the
7094 same name). In addition, the debugfs program and the open_filesystem
7095 command now takes three new options: -b and -s, which allows the
7096 blocksize and superblock location to be specified, and the -c option
7097 which is used in catastrophic situations where the block group
7098 descriptors are corrupt. If the -c option is specified, debugfs will
7099 skip trying to read in the block and inode bitmaps.
7101 Debufs's lsdel command was fixed to handle bad blocks in the inode
7104 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
7107 General improvements in error messages
7109 - Mke2fs prints a sane error message if the partition size is zero
7110 (usually because the partition table wasn't reread by the
7111 kernel due to the partition being busy), instead of "invalid
7112 argument passed to ext2 library while initializing superblock".
7114 - Fsck now prints more self-explanatory message if an invalid UUID=
7115 or LABEL= specification is passed to it.
7117 UUID library changed to use the LGPL.
7119 Fixed a bug in the UUID library where very rapid calls to the
7120 time-based UUID generator could cause duplicate UUID's to be returned.
7121 This was not a problem for e2fsprogs, but it could be a problem for
7122 other users of the library.
7124 Make the UUID library more robust in the face of missing or an
7125 improper /dev/urandom or /dev/random files.
7127 Added some random portability fixes for Solaris.
7129 Some minor man page updates.
7131 Fixed a memory leak in the ss library.
7137 We now try to use lseek64 and open64 from the LFS if possible.
7139 The 3rd parameter in e2p's print_flags is now a flags word, instead of
7142 The mark and unmark bitmap functions now return the previous state of
7143 the bit that was being changed, which is useful for some speed
7146 The following functions have been added to enhance the badblocks list
7147 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
7148 ext2fs_badblocks_equal.
7150 The ext2 header files now have the latest journalling fields to the
7153 The ext2fs_mkdir function in libext2fs now properly backs out of error
7154 conditions robustly.
7156 Cleaned up makefiles:
7157 - to cleanly compile with the -j flag.
7158 - so distclean removes all generated files.
7159 - so in case of an error while installing header files, the make aborts.
7161 Fix test_script so that it works correctly when compiling in the
7164 The random UUID generation routine has been made slightly better in
7165 the case where /dev/random doesn't exist. (Use of randomly-based UUID
7166 is still not recommended if /dev/random doesn't exist, however; it's
7167 better to use the time/ethernet MAC address UUID in this case.)
7169 Clean up the build process so it's more friendly in case of missing
7172 The ext2fs header file can now be #include'd into C++ programs.
7174 The e2p.h header file is now installed.
7176 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
7180 E2fsprogs 1.18 (November 10, 1999)
7181 ==================================
7183 Fix a core dumping bug in e2fsck if an imagic inode is present or
7184 (more rarely) if the filesystem is badly corrupted enough that e2fsck
7185 has to restart pass 1 processing. E2fsck now closes the filesystem
7186 before freeing a large number of its data structures, so in the case
7187 of future memory faults, at least the fixed filesystem will be fully
7190 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
7191 imagic inode, it will offer to clear the imagic flag.
7193 E2fsck will now offer to clear the immutable flag on special files
7194 (device/socket/fifos) when running it in non-preen mode.
7196 E2fsck will now set the filetype when creating /lost+found, and when
7197 connected orphaned inodes to /lost+found.
7199 Debugfs's ncheck and icheck commands now handles the case where there
7200 are bad blocks in the inode table without bombing out.
7202 The badblocks list processing code has been made more efficiently for
7203 appending a large number of (ordered) badblocks to the badblocks list.
7205 Some minor man page updates.
7207 Fsck now allows interactive e2fsck's when using fsck -As (not a common
7208 mode, but some people like to do this in boot scripts for silly reasons).
7213 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
7214 with the problem code convention.
7216 The badblocks list regression test program has been updated to work
7217 with previously made API name changes.
7219 The ext2fs_free() command now uses the new badblocks API to avoid
7220 using the compatibility layer.
7222 Added new regression test cases; the run_e2fsck test script now
7223 supports the ability for a test case to run a prepratory command
7224 before running e2fsck.
7226 E2fsprogs 1.17 (October 26, 1999)
7227 =================================
7229 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
7232 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
7233 thus potentially causing problems if a binary UUID contained a NULL
7236 E2fsck now uses stricter checks for directory entries in pass 2:
7237 zero-length filenames are not allowed; neither are 8 byte long
7240 The debugfs "dirty" command now clears the filesystem valid bit.
7241 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
7242 bit in the in-core superblock image. The new functionality is more
7243 what the user expects, and is more useful.)
7245 Added a debugging hook to test parallel fsck; if the environment
7246 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
7247 will be checked in parallel when they normally would not be.
7252 Fixed some #ifdef's for compilation under the Hurd OS.
7254 Fixed minor W2K compatibility problems.
7256 Fixed some miscellaneous GCC warnings.
7259 E2fsprogs 1.16 (October 22, 1999)
7260 =================================
7262 Fixed a race condition bug in fsck; when printing a progress bar, if
7263 checking multiple filesystems in parallel, it was possible for fsck to
7264 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
7265 handler, which would cause it to terminate with a signal 10.
7267 E2fsck now properly handles filesystems that have the
7268 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
7269 filesystem into using or not using FILETYPE feature.
7271 E2fsck now properly handles filesystems that have the IMAGIC feature
7272 turned on (this is used on Linux AFS servers).
7274 The mke2fs program now creates filesystems that have the filetype and
7275 sparse_superblock features enabled by default, unless it is run on a
7276 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
7277 so there is now a new flag -O which allows the user to specify with
7278 which features she would like to create the filesystem; "mke2fs -O
7279 none" will create a filesystsem compatible with 2.0 kernels.
7281 The tune2fs program now has a -O option which allows the user to set
7282 and reset "safe" filesystem features. Currently, the only ones which
7283 allows to be modified are the filetype and sparse_superblock features.
7284 Note setting or clearing either feature will require running e2fsck on
7285 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
7286 requires that there is enough free space on the filesystem for the
7287 extra superblocks which will be created by e2fsck.)
7289 Debugfs can now set and print filesystem features in the superblock
7290 using the "features" command. Dumpe2fs will print out the complete
7291 set of features when listing the superblock.
7293 Dumpe2fs has new options -f (force) and -h (header-only).
7295 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
7296 message to come up. This could happen when decrementing or
7297 incrementing a link count could result in an overflow.
7299 Fixed a bug in e2fsck where the block count on the lost+found
7300 directory would not be properly incremented when the directory was
7301 expanded to the point where an indirect block needed to be allocated.
7303 E2fsck now makes some additional sanity checks on the superblock to
7304 avoid crashing or giving a memory allocation error if some of the
7305 values in the superblock are unresonable (but the superblock otherwise
7308 Fixed a bug in e2fsck where a very badly corrupted filesystem might
7309 require two passes to completely fix the filesystem. This happened if
7310 an inode claimed blocks that was part of the filesystem metadata
7311 (typically, when garbage was written into an inode table or indirect
7312 block, since this kind of filesystem corruption normally doesn't
7315 On the Alpha, glibc declares st_flags although it isn't actually used;
7316 the configure script was improved to detect this case so that
7317 e2fsprogs can avoid using the non-functional stat field.
7319 The manual pages were updated to use a more consistent formatting
7320 style consistent with standard Unix man pages. Mke2fs's man page
7321 added documentation for a few previously undocumented options.
7323 Fixed minor display bugs in tune2fs and mke2fs.
7328 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
7330 Added features to parse and print feature strings into the e2p library.
7331 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
7333 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
7334 whose directory entries contain proper filetype information if the
7335 filesystem supports it.
7337 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
7338 the directory entry filetype information. This is used to set the
7339 directory entry filetype information if the filesystem supports it.
7341 Fixed a bug in ext2fs_expand_dir() where the block count in a
7342 directory's inode would not be properly incremented when the directory
7343 was expanded to the point where an indirect block needed to be
7347 E2fsprogs 1.15 (July 18, 1999)
7348 ==============================
7350 Add configuration checks so that e2fsprogs will compile cleanly on
7351 Linux 2.3 kernels that have renamed i_version to i_generation.
7353 E2fsck now prints a progress/completion bar (and not just a simple
7354 spinner) if the -C0 option is requested or if it receives a SIGUSR1
7355 signal. Fsck will automatically manage the (potentially muliple)
7356 e2fsck processes to print completion bars if it is given a -C option,
7357 with the right thing happening if multiple filesystems are being
7358 checked in parallel.
7360 Mke2fs now has better automatic hueristics to determine the filesystem
7361 parameters to be used for a particular filesystem. Added a new option
7362 -T which allows the user to specify how the filesystem is to be used,
7363 which helps mke2fs do a better job selecting the filesystem parameters.
7365 Mke2fs now creates revision 1 filesystems by default, and with the
7366 sparse superblock feature enabled. The sparse superblock feature is
7367 not understood by Linux 2.0 kernels, so they will only allow read-only
7368 mounts of filesystems with this sparse superblocks.
7370 Fix bug where if /dev/null couldn't be opened (should never happen),
7371 e2fsck would hang in a tight loop.
7373 Make e2fsck handle the case where /lost+found isn't a directory.
7375 E2fsck now uses mallinfo if it exists to get accurate statistics about
7378 Fix bug in e2fsck where it wouldn't check to see if a disconnected
7379 inode had any problems before connecting it to /lost+found.
7381 Add check to e2fsck so it makes sure that total number of inodes in
7382 the filesystem is a sane number.
7384 Fix fencepost error when clearing an the end of the block bitmap which
7385 caused the last block in the bitmap not to get cleared.
7387 Cleaned up a number of messages in e2fsck:
7388 * The message "Group's #'s copy of the group descriptor..."
7389 was fixed so that the correct number would be displayed.
7390 * Added missing space in the "disk write-protected" error messsage
7391 * Cleaned up the error message printed when a non-interactive
7392 e2fsck needs to abort a check because the filesystem
7393 appears to be mounted.
7395 Added a new command-line utility, uuidgen, which will create and print
7398 Make debugfs's icheck command more robust by checking to make sure an
7399 inode has valid blocks before interarting over the inode's blocks.
7401 UUID generation now uses a random-based scheme whenever possible to
7402 prevent potential privacy problems.
7404 Man pages for all of the UUID functions in the lirbary were added.
7406 Fixed bug in fsck so it won't coredump if a filesystem not in
7407 /etc/fstab is given to it.
7409 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
7410 that most of the other mount utilities understands.
7412 Mke2fs will make a filesystem even if it appears mounted if the force
7415 Dumpe2fs has new command-line options which allow a filesystem expert
7416 to specify the superblock and blocksize when opening a filesystem.
7417 This is mainly useful when examining the remains of a toasted
7420 The badblocks program has been updated to display correctly on disks
7421 with large block numbers.
7423 The badblocks program no longer gives spurious errors when errors
7424 occur on non-block boundaries, which is common if the blocksize is
7427 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
7428 MKE2FS_SYNC environment variable is set. This is to work around a VM
7429 bug in the 2.0 kernel. I've heard a report that a RAID user was able
7430 to trigger it even using a 2.2 kernel, but hopefully it will not be
7431 needed for most Linux 2.2 users.
7433 Fixed miscellaneous documentation and man pages.
7438 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
7439 in e2fsck's pass1.c really should have been static.
7441 The return value of the uuid_compare() function was changed to make it
7442 match with the convetions used by strcmp, memcmp, and Paul Leach's
7443 UUID sample document.
7445 The "make depend" process has now been made more automated; it now
7446 automatically word-wraps the dependencies, and only replaces source
7447 Makefile.in if there has been a change in the dependencies. Also, a
7448 top-level "make depend" now recurses through all the subdirectories
7451 The Makefile in .../util has been changed so that subst is built using
7452 the native C compiler during a cross-compilation, since the subst
7453 program is only used during the build process. Also add an explicit
7454 rule to build util/subst by cd'ing to the correct directory and
7457 The man directories are defined in terms mandir, so that the configure
7458 script can override the location of the manual pages.
7460 The config files have been updated to recognize new machine types for
7461 both the i386 and alpha families.
7463 Fsck has been modified so that it will accurately create an
7464 fsck_instance even when the noexecute flag is set. This allows for
7465 accurate debugging of the fsck pass structure. Also, when the verbose
7466 flag is given twice, fsck will print debugging information about when
7467 fsck is waiting for jobs to finish.
7470 E2fsprogs 1.14 (January 9, 1999)
7471 ================================
7473 Fix the fstab parsing code so that it can handle blank lines and
7474 comment characters. Also, missing pass numbers need to be treated as
7477 Fixed a bug in e2fsck where under some circumstances (when e2fsck
7478 needs to restart processing after fixing an egregious inconsistency)
7479 it would try to access already freed memory.
7481 E2fsck now prints non-printable characters in directory entries and
7482 pathnames using '^' and 'M-' notation.
7484 Fixed chattr so that it will ignore symbolic links when doing
7485 recursive descent traversals. For both chattr and lsattr, no longer
7486 print the version string unless the -V option is given.
7488 Allow the system administrator to directly specify the number of
7489 inodes desired in the filesystem, for some special cases where this is
7492 Fix portability problems so that e2fsprogs can be compiled under Linux
7493 1.2 systems and Solaris systems.
7495 Update the config.guess file with a more recent version that will
7496 identify newer Linux platforms.
7501 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
7502 an inode number of zero is passed to them.
7504 E2fsprogs 1.13 (December 15, 1998)
7505 ==================================
7507 Fixed a bug in debugfs where an error messages weren't getting printed
7508 when the ext2 library routines to read inodes returned errors in the
7509 stat, cmri and rm commands.
7511 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
7512 provided, it won't create an inode table smaller than the minimum
7513 number of inodes required for a proper ext2 filesystem.
7515 Fsck now parses the /etc/fstab file directly (instead of using
7516 getmntent()), so that it can distinguish between a missing pass number
7517 field and pass number field of zero. This caused problems for
7518 diskless workstations where all of the filesystems in /etc/fstab have
7519 an explicit pass number of zero, and fsck could not distinguish this
7520 from a /etc/fstab file with missing pass numbers.
7522 E2fsck will create a /lost+found directory if there isn't one in the
7523 filesystem, since it's safer to create the lost+found directory before
7526 Fixed e2fsck so that it would detect bogus immutable inodes which
7527 happen to be sockets and FIFO files, and offer to clear them.
7529 If a filesystem has multiple reasons why it needs to be checked, and
7530 one of the reasons is that it is uncleanly mounted, e2fsck will print
7531 that as the reason why the filesystem is being checked.
7533 Cleaned up the output routines of mke2fs so that it doesn't overflow
7534 an 80 column display when formating really big filesystems.
7536 Added a sanity check to e2fsck to make sure that file descriptors 0,
7537 1, 2 are open before opening the hard disk. This avoids a problem
7538 where a broken program might exec e2fsck with those file descriptors
7539 closed, which would cause disastrous results if the kernel returns a
7540 file descriptor for the block device which is also used by FILE *
7543 Fixed up the e2fsck progress reporting functions so that the values
7544 reliably reach 100% at the completion of all of the e2fsck passes.
7546 Fixed minor documentation bugs in man pages and usage messages.
7551 Fixed a number of lint warnings in the ext2fs library and potential
7552 portability problems from other OS's header files that might define
7553 CPP macros for names like "max" and "min".
7555 ext2fs_badblocks_list_add() has been made more efficient when it needs
7556 to grow the bad blocks list.
7558 Fixed a bug in e2fsck which caused it to dereference a freed pointer
7559 just before exiting.
7561 Fixed the substition process for generating the mk_cmds and compile_et
7562 scripts so that they will work outside of the build tree.
7564 Add sanity check to e2fsck so that if an internal routine
7565 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
7566 and causing a core dump. This should never happen, but...
7568 E2fsprogs 1.12 (July 9, 1998)
7569 ==================================
7571 E2fsprogs now works with glibc (at least with the version shipped wtih
7572 RedHat 5.0). The ext2fs_llseek() function should now work even with
7573 i386 ELF shared libraries and if llseek() is not present. We also
7574 explicitly do a configure test to see if (a) llseek is in libc, and
7575 (b) if llseek is declared in the system header files. (See standard
7576 complaints about libc developers don't understand the concept of
7577 compatibility with previous versions of libc.)
7579 The ext2fs library now writes out the block group number in each of
7580 the superblock copies. This makes it easier to automatically
7581 determine the starting block group of the filesystem when the block
7582 group information is trashed.
7584 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
7585 which means that e2fsprogs will ignore the high 8 bits of the
7586 directory entry's name_len field, so that it can be used for other
7589 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
7590 E2fsprogs will now support filesystems with 64-bit sized files.
7592 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
7594 Added new program "e2label", contributed by Andries Brouwer. E2label
7595 provides an easy-to-use interface to modify the filesystem label.
7597 Fixed bug so that lsattr -v works instead of producing a core dump.
7599 Fixed a minor bug in mke2fs so that all groups with bad superblock
7600 backup blocks are printed (not just the first one).
7602 Mke2fs will check the size of the device, and if the user specifies a
7603 filesystem size larger than the apparent size of the device it will
7604 print a warning message and ask if the user wants to proceed.
7606 E2fsck has a new option -C, which sends completion information to the
7607 specified file descriptor. For the most part, this is intended for
7608 programs to use, although -C 0 will print a spinning character to the
7609 stdout device, which may be useful for users who want to see something
7610 happening while e2fsck goes about its business.
7612 Fixed a bug in e2fsck which could cause a core dump when it needs to
7613 expand the /lost+found directory, and sometimes the bitmaps haven't
7614 been merged in. Also fixed a related bug where ext2fs_write_dir_block
7615 was used to write out a non-directory block. (Which would be bad on a
7616 non-Intel platform with byte swapping going on.)
7618 Fixed bug in e2fsck where it would print a "programming error" message
7619 instead of correctly identifying where a bad block was in used when
7620 the bad block was in a non-primary superblock or block group
7621 descriptor. Also fixed a related bug when sparse superblocks are in
7622 use and there is a bad block where a superblock or block group
7623 descriptor would have been in a group that doesn't include a
7626 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
7627 the block group descriptor table is corrupt, it was possible to try to
7628 allocate a huge array, fail, and then abort e2fsck.
7629 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
7630 and subsitutes reasonable values if the descriptors are obviously bogus.
7632 If e2fsck finds a device file which has the immutable flag set and the
7633 i_blocks beyond the normal device number are non-zero, e2fsck will
7634 offer to remove it, since it's probably caused by garbage in the inode
7637 When opening a filesystem, e2fsck specially checks for the EROFS error
7638 code, and prints a specific error message to the user which is more
7641 If the filesystem revision is too high, change the e2fsck to print
7642 that this is either because e2fsck is out of date, or because the
7643 superblock is corrupt.
7645 E2fsck now checks for directories that have duplicate '.' and '..'
7646 entries, and fixes this corruption.
7648 E2fsck no longer forces a sync of the filesystem (with attendant sleep
7649 calls) at all times. The ext2fs_flush() function now performs a sync
7650 only if it needed to write data blocks to disk.
7652 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
7653 certain errors would not be properly reported.
7655 Updated and expanded a few points in the man pages which users
7656 complained wheren't explicit enough.
7658 Added special case byte-swapping code if compiling on the PowerPC, to
7659 accomodate the strange big-endian variant of the ext2 filesystem that
7660 was previously used on the PowerPC port.
7666 Removed C++ keywords from the ext2fs libraries so that it could be
7669 E2fsck's internal organization has now been massively reorganized so
7670 that pass*.c don't have any printf statements. Instead, all problems
7671 are reported through the fix_problem() abstraction interface. E2fsck
7672 has also been revamped so that it can be called as a library from a
7675 Added new fileio primitives in libext2fs for reading and writing
7676 files on an unmounted ext2 filesystem. This interface is now used by
7679 Added a new libext2fs function for mapping logical block numbers of
7680 a file to a physical block number.
7682 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
7683 a block, zeros it, and updates the filesystem accounting records
7686 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
7687 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
7689 The libext2fs functions now use a set of memory allocation wrapper
7690 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
7691 instead of malloc, free, and resize. This makes it easier for us to
7692 be ported to strange environments where malloc, et. al. aren't
7693 necessarily available.
7695 Change the libext2fs fucntion to return ext2-specific error codes
7696 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
7697 and depending on the existence of system error codes (such as EEXIST
7700 Renamed io.h to ext2_io.h to avoid collision with other OS's header
7703 Add protection against ext2_io.h and ext2fs.h being included multiple
7706 The types used for memory lengths, etc. have been made more portable.
7707 In generla, the code has been made 16-bit safe. Added Mark
7708 Habersack's contributed DOS disk i/o routines.
7710 Miscellaneous portability fixes, including not depending on char's
7713 The io_channel structure has a new element, app_data, which is
7714 initialized by the ext2fs routines to contain a copy of the filesystem
7717 ext2fs_check_directory()'s callback function may now return the error
7718 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
7719 really do the checking, despite the presence of the callback function.
7722 E2fsprosg 1.11 (June 17, 1997)
7723 ==============================
7725 Fixed e2fsck to detect (previously ignored) conflicts between the
7726 superblock or block group descriptors and block bitmaps, inode
7727 bitmaps, and inode tables.
7729 Fixed bug in e2fsck so that when the message printed out when a block
7730 or inode bitmap conflicts with other data, it has the correct group
7733 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
7734 to badblocks. This meant that not all of the filesystem was being
7735 tested for bad blocks!
7737 Fixed an array boundary overrun case which cropped up in
7738 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
7741 Adjusted the number of columns printed by mke2fs when displaying the
7742 superblock backups to avoid running over 80 columns when making a
7743 really big filesystem.
7745 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
7746 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
7747 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
7752 Fixed install rule in lib/ss so that ss_err.h is actually getting
7755 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
7756 bassed back to the caller.
7758 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
7759 setting the current inode number (which meant this function wasn't
7762 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
7763 blocks in the bitmap when increasing the size of the bitmap.
7765 Changed the initial number of blocks allocated by ext2fs_init_dblist()
7766 to be more realistic.
7768 Added a new function ext2fs_allocate_group_table, which sets up the
7769 group descriptor information (and allocates inode and block bitmaps,
7770 and inode tables for a particular group). The function was created by
7771 factoring out code form ext2fs_allocate_tables().
7773 Added a new function ext2fs_move_blocks which takes a bitmap of the
7774 blocks to be moved, and moves them to another location on the
7777 Make the unix_io channel's io_channel_flush implementation calls sync()
7778 to to flush the kernel buffers to disk.
7780 Added a new function ext2fs_dblist_count returns the number of
7781 directory blocks in dblist.
7784 E2fsprogs 1.10 (April 24, 1997)
7785 ===============================
7787 Mke2fs once again defaults to creating revision #0 filesystems, since
7788 people were complaining about breaking compatibility with 1.2 kernels.
7789 Warning messages were added to the mke2fs and tune2fs man pages that
7790 the sparse superblock option isn't supported by most kernels yet (1.2
7791 and 2.0 both don't support parse superblocks.)
7793 Added new flag to mke2fs, -R <raid options>, which allows the user to
7794 tell mke2fs about the RAID configuration of the filesystem. Currently
7795 the only supported raid option is "stride" which specifies the width
7798 Fixed bug in e2fsck where pass1b would bomb out if there were any
7799 blocks marked bad in the inode table.
7801 Fixed rare bug in mke2fs where if the user had a very unlucky number
7802 of blocks in a filesystem (probability less than .002) the resulting
7803 filesystem would be corrupt in the last block group.
7805 Fixed bug where if e2fsck tried to allocate a block to fix a
7806 filesystem corruption problem and the filesystem had no free blocks,
7807 ext2fs_new_block() would loop forever.
7809 The configure script now checks explicitly to see if "-static" works,
7810 since that can't be assumed to be true --- RedHat doesn't install
7811 libc-static by default.
7813 Fixed bug in libext2's block iterator functions where under some
7814 cirmcustances, file with holes would cause the bcount parameter to the
7815 callback function to be incorrect. This bug didn't affect any of
7816 e2fsprogs programs, but it was discovered by Paul Mackerras, the
7817 author of the PPC boot loader.
7819 Removed use of static variables to store the inode cache in libext2fs.
7820 This caused problems if more than one filesystem was accessed via
7821 libext2fs (static variables in libraries are generally a bad idea).
7822 Again, this didn't affect e2fsprogs programs, but it was discovered by
7825 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
7826 will compile cleanly with 1.2.13 kernels (even with a.out shared
7832 Added new functions to duplicate an ext2 filesystem handle, and its
7833 associated substructure. New functions: ext2fs_dup_handle(),
7834 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
7835 Other structures, such as the io_channel and the inode_cache, now have
7836 a ref count so that they only get freed when they are no longer used
7837 by any filesystem handle. (These functions were added as part of the
7838 development effort for an ext2 resizer).
7840 E2fsprogs 1.09 (April 14, 1997)
7841 ===============================
7843 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
7844 accidentally introduced in the 1.08 release. The overhead calculation
7845 was accidentally removed, which caused ext2fs_initialize() to not
7846 notice when the filesystem size needed to be adjusted down because
7847 there wasn't enough space in the last block group.
7849 Fixed bug in version parsing library routine; it was always parsing
7850 the library version string, instead of using the passed-in string.
7852 Clarified chattr man page.
7854 E2fsprogs 1.08 (April 10, 1997)
7855 ===============================
7857 E2fsck 1.07 was very slow when checking very large filesystems with a
7858 lot of files that had hard links (i.e., news spools). This was fixed
7859 by seriously revamping the icount abstraction. Added a formal test
7860 suite for the icount abstraction.
7862 Debugfs now has a "-l" option to the "ls" command, which lists the
7863 inode number, permissions, owner, group, size, and name of the files
7866 Fix a bug in e2fsck where when a directory had its blocks moved to
7867 another location during the pass 1b processing, the directory block
7868 list wasn't updated, so pass 2 wouldn't check (and correct) the
7869 correct directory block.
7871 E2fsck will now treat inodes which contain blocks which are claimed by
7872 the filesystem metadata by treating them as multiply claimed blocks.
7873 This way, the data in those blocks can be copied to a new block during
7874 the pass 1b--1d processing.
7876 E2fsck will attempt to determine the correct superblock number and
7877 display it in the diagnostic and warning messages if possible.
7879 Add support for a new (incompatible) feature, "sparse_super". This
7880 feature reduces the number of blocks which contain copies of backup
7881 superblocks and block group descriptors. (It is only an incompatible
7882 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
7883 support a new -s option; e2fsck will recognize filesystems built with
7884 this feature turned on.
7886 E2fsck now checks the library to make sure is the correct version,
7887 using new library functions. (This helps to diagnose incorrectly
7888 installed e2fsprogs distributions.)
7890 Dumpe2fs now prints more information; its now prints the the
7891 filesystem revision number, the filesystem sparse_super feature (if
7892 present), the block ranges for each block group, and the offset from
7893 the beginning of the block group.
7895 Mke2fs now distributes the inode and block bitmap blok so that the
7896 won't be concentrated in one or two disks in RAID/striping setups.
7897 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
7898 choose the largest blocks per group that be chosen. (For 2k blocks,
7899 you can have up to 16384 blocks/group; for 4k blocks, you can have up
7900 to 32768 blocks/group.) Previously mke2fs would not allow
7901 specification of more than 8192 blocks per group, even if you were
7902 using a 2k or 4k block group.
7907 Added a new function ext2fs_create_icount2() which takes a "hint"
7908 argument. This hint argument presets the icount array with the list
7909 of inodes which actually need to be in the icount array. This really
7910 helps to speed up e2fsck.
7912 Added a new function ext2fs_icount_validate() which checks the rep
7913 invariant for the icount structure. This is used mostly for testing.
7915 The error mesasage given when a bad inode number is passed to
7916 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
7917 EXT2FS_UNMARK_ERROR).
7919 Added a new function ext2fs_set_dir_block which sets the block of a
7920 dblist entry, given the directory inode and blockcnt.
7922 Added a new function ext2fs_get_library_version() which returns the
7923 current library version, and ext2fs_parse_version_string() which
7924 returns a version number based on a e2fsprogs version string.
7926 The icount functions will return EINVAL if the passed in inode number
7929 E2fsprogs 1.07 (March 9, 1997)
7930 ==============================
7932 E2fsck is now uses much less memory when checking really large
7933 filesystems (or rather, filesystems with a large number of inodes).
7934 Previously a filesystem with 1 million inodes required 4 megabytes of
7935 memory to store inode count statistics; that storage requirement has
7936 now been reduced to roughly half a megabyte.
7938 E2fsck can now properly deal with bad blocks appearing inside the
7939 inode table. Instead of trying to relocate the inode table (which
7940 often failed because there wasn't enough space), the inodes in the bad
7941 block are marked as in use.
7943 E2fsck will automatically try to use the backup superblocks if the
7944 primary superblocks have a bad magic number or have missing meta-data
7945 blocks (or meta-data blocks which are out of range).
7947 E2fsck's pass 3 has been made more efficient; most noticeable on
7948 filesystems with a very large number of directories.
7950 Completely revamped e2fsck's system of printing problem reports. It
7951 is now table driven, to make them more easily customizeable and
7952 extendable. Error messages which can be printed out during preen mode
7953 are now one line long.
7955 Fixed e2fsck's filesystem swapping code so that it won't try to swap
7956 fast symbolic links or deleted files.
7958 Fixed e2fsck core dumping when fixing a filesystem which has no
7959 directories (not even a root directory).
7961 Added a check to e2fsck to make sure that the length of every
7962 directory entry is a multiple of 4 (since the kernel complains if it
7965 Added a check to e2fsck to make sure that a directory entry isn't a
7966 link to the root directory, since that isn't allowed.
7968 Added a check to e2fsk to now make sure the '.' and '..' directory
7969 entries are null terminated, since the 2.0 kernel requires it.
7971 Added check to write_bitmaps() to make sure the superblock doesn't get
7972 trashed if the inode or block bitmap is marked as being block zero.
7974 Added checking of the new feature set fields in the superblock, to
7975 avoid dealing with new filesystem features that this package wasn't
7978 Fixed a fencepost error in ext2fs_new_block() which would occasionally
7979 try to allocate a block beyond the end of a filesystem.
7981 When the UUID library picks a random IEEE 802 address (because it
7982 can't find one from a network card), it sets the multicast bit, to
7983 avoid conflicting with a legitimate IEEE 802 address.
7985 Mke2fs now sets the root directory's owner to be the real uid of the
7986 user running mke2fs. If the real uid is non-zero, it also sets
7987 the group ownership of the root directory to be the real group-id of
7988 the user running mke2fs.
7990 Mke2fs now has more intelligent error checking when it is given a
7991 non-existent device.
7993 When badblocks is given the -vv option, it now updates the block that
7994 it is currently testing on every block.
7996 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
7997 currently correctly if PATH wasn't already set.
7999 Shared libraries now built with dependencies. This allows the shared
8000 library files to be used with dlopen(); it also makes the transition
8001 to libc 6 easier, since ld.so can tell which libc a particular shared
8002 library expects to use.
8007 Added new abstraction (defined in dblist.c) for maintaining a list of
8008 blocks which belongs to directories. This is used in e2fsck and other
8009 programs which need to iterate over all directories.
8011 Added new functions which test to see if a contiguous range of blocks
8012 (or inodes) are available. (ext2fs_*_bitmap_range).
8014 Added new function (ext2_inode_has_valid_blocks) which returns true if
8015 an inode has valid blocks. (moved from e2fsck code).
8017 Added new function (ext2fs_allocate_tables) which allocates the
8018 meta-data blocks as part of initializing a filesystem. (moved from
8021 Added a new I/O manager for testing purposes. It will either allow a
8022 program to intercept I/O requests, or print debugging messages to
8023 trace the activity of a program using the I/O manager.
8025 The badblocks_list functions now store the bad blocks in a sorted
8026 order, and use a binary search to speed up badblocks_list_test.
8028 The inode scan function ext2fs_get_next_inode() may now return a soft
8029 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
8030 those cases where part of an inode table is missing or there is a bad
8031 block in the inode table.
8033 Added a new function (ext2fs_block_iterate2) which adds new arguments to
8034 the callback function to return a pointer (block and offset) to the
8035 reference of the block.
8037 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
8038 application to jump to a particular block group while doing an inode
8041 The badblocks list functions were renamed from badblocks_* to
8042 ext2fs_badblocks_*. Backwards compatibility functions are available
8043 for now, but programs should be modified to use the new interface.
8045 Some of the library functions were reorganized into separate files to
8046 reduce the size of some programs which statically link against the
8049 Put in some miscellaneous fixes for the Alpha platform.
8052 E2fsprogs 1.06 (October 7, 1996)
8053 ================================
8055 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
8056 smash the backup copies in ext2fs_close(). (The problem was that when
8057 e2fsck -p discovered the problem, while it was closing the filesystem
8058 and exiting, it was also blowing away the backup superblocks on the
8059 disk, which was less than friendly.) We now make it the case that we
8060 only write out the backup superblock and the back block descriptors if
8061 the filesystem is completely free from problems.
8063 Fixed a bug in block_interate in the lib/ext2fs library which caused
8064 e2fsck to fail on GNU Hurd-created filesystems.
8066 Add support for Linux/FT's bootloader, which actually uses
8067 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
8070 Add support for the "A" (no atime update) attribute. (Note: this
8071 attribute is not yet in production kernels.)
8073 The test suite is not automatically run when doing a "make all" from
8074 the top level directory. Users should manually run "make check" if
8075 they wish to run the test suite.
8077 Upon a preenhalt(), make the printed message more explicit that
8078 running e2fsck "MANAULLY" means without the -p or -a options.
8080 In e2fsck, if a disconnected inode is zero-length, offer to clear it
8081 instead of offering to connect it to lost+found.
8083 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
8084 e2fsck to be run over it, change e2fsck to explicitly display this
8087 For dumpe2fs and e2fsck, cause the -V option to print out which
8088 version of the ext2fs library is actually getting used. (This will
8089 help detect mismatches of using a 1.06 utility with a 1.05 library,
8095 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
8096 the naming convention.
8098 In ext2fs_initialize(), make sure the description for the inode bitmap
8099 is correctly initialize.
8101 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
8103 E2fsprogs 1.05 (September 7, 1996)
8104 ==================================
8106 Add support for new fields in the ext2 superblock --- volume name,
8107 volume UUID, and last mounted field. Dumpe2fs displays these fields,
8108 tune2fs and mke2fs allows you to set them. E2fsck will automatically
8109 generate a UUID for those volumes that don't have them.
8111 Put in support for e2fsck to recognize HURD specific ext2 features ---
8112 most notably, the translator block. The e2fsprogs tools will now use
8113 the creator_os field in the superblock to correctly handle different
8114 OS-specific variants of the ext2 filesystem.
8116 E2fsck now fixes inodes which have a the deletion time set, but which
8117 have a non-zero i_link_count field by offering to clear the deletion
8118 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
8119 ext2 kernel behavior) and offered to unlink the file.
8121 If e2fsck sets the clean bit, but nothing else, set the exit code
8122 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
8123 set the filesystem valid bit when it was previously cleared. :-) This
8124 was needed to make the HURD fsck driver happy.
8126 If the user refuses to attach an unattached inode, e2fsck will no
8127 longer set the inode's link count. Otherwise, the inode would end up
8128 getting marked as unused, which might cause loss of data later.
8130 Make the message issued by e2fsck when the superblock is corrupt less
8131 confusing for users. It now mentions that another reason for the
8132 "corrupt superblock" message might be that the partition might not be
8133 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
8135 Make the libext2 library more robuest so that e2fsck won't coredump on
8136 an illegal superblock where the blocksize is zero. (f_crashdisk is
8139 By default, create filesystems where the default checkinterval is 6
8140 months (180 days). Linux servers can be robust enough that 20 reboots
8141 can be a long, long time.
8143 Added configure flag --enable-old-bitops, which forces the bitops to
8144 use the old (native) bitmask operations. By default on the sparc
8145 platform, the standard ext2 bit ordering is now used.
8147 Added a new feature to e2fsck to byte-swap filesystems; this can be
8148 used to convert old m68k filesystems to use the standard byte-order
8149 storage for the superblock, inodes, and directory blocks. This
8150 function is invoked by using the '-s' option to e2fsck.
8152 Debugfs's "dump" command has been enhanced so that it writes out the
8153 exact size of the file so that the nulls at the end of the file are
8154 eliminated. The command also accept a new "-p" option which will
8155 attempt preserve to preserve the ownernship, permissions, and
8156 file modification/access times.
8158 Debugfs has two new options, -f and -R. The -R option allows the user
8159 to execute a single debugfs command from the command line. The -f
8160 option allows the user to specify a "command file" containing debugfs
8161 commands which will get executed.
8163 Dumpe2fs now pretty prints the check interval, instead of just
8164 printing the check interval as a number of seconds.
8166 Fix bugs in debugfs: the params command when no filesystem is opened
8167 no longer causes a core dump. It is now possible to unlink a file
8168 when a pathame containing a '/' is specified.
8170 Tune2fs has a new -C option which sets the number of times the
8171 filesystem has been mounted.
8173 Fix the chattr '-v' option so that it actually works. Chattr was
8174 being buggy about the -v option parsing.
8179 The directory lib/uuid contains a set of library routines to generate
8180 DCE compatible UUIDs.
8182 Extended ext2fs_namei() to handle symbolic links. Added new function
8183 ext2fs_nami_follow() which will follow last symbolic link in the case
8184 where the pathname points to a sym link.
8186 The ext2fs_block_iterate function will now return the HURD translator
8187 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
8188 iterator to return data blocks only. The ext2fs.h file now defines
8189 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
8190 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
8191 count field of the iterator callback function.
8193 The test script driver now takes an optional second argument, which is
8194 the test case to be run. This allows you to run a test case without
8195 needing to run the entire test suite.
8197 On Linux ELF systems, install the .so files in the correct places
8198 (/usr/lib). The .so files must be stored in the same directory as the
8201 Fixed miscellaneous HURD compilation issues with header file being
8202 included in the right order.
8204 Fixed debugfs so that it resets optind to zero, not one, since setting
8205 optind to zero is more correct.
8208 E2fsprogs 1.04 (May 16, 1996)
8209 =============================
8211 First "official" (1.03 was a limited release only) to support building
8212 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
8215 This package includes a RPM specs file, that it can be built using the
8216 RedHat Package Manager.
8218 E2fsck now prints a hint that if there are lots of incorrectly located
8219 inode bitmaps, block bitmaps, and inode table blocks, the user might
8220 want to try using e2fsck -b 8193 first, to see if that fares any
8223 For ext2 filesystem written with the hurd, debugfs will now print out
8224 the translator field when printing an inode structure.
8226 Lots of miscellaneous linking/installation cleanups:
8228 Libraries are now linked using a relative pathname, instead of
8229 relying on -L working correct. It doesn't, in many cases, including
8230 current versions of GNU ld. This guarantees that the build tree is
8231 linking with the right libraries, instead of the ones installed in
8234 Header files, man pages, and the et/ss shell scripts are now
8235 generated using a custom substitution script, instead of relying on
8236 the configure script. This prevents needless recompilation of
8237 files; in addition, the custom substitution script is much faster.
8239 e2fsck may now be linked dynamically, by using the
8240 --enable-dynamic-e2fsck flag to configure. This is not recommended,
8241 since it increases e2fsck's dependence on other files, but some
8242 people need to save disk space, and other critical programs on their
8243 systems were being linked dynamically anyway.
8245 Programs such as fsck which didn't need to be linked against
8246 libext2fs (or mke2fs which didn't need to be linked against libe2p)
8247 only link against libraries they actually need. Otherwise, those
8248 programs would require the presense of libraries that otherwise
8249 could be removed from a rescuse diskette.
8251 The ss include files are now installed correctly so they can
8252 actually be used by another package.
8254 If the profiling libraries are built, they are now installed on a
8255 "make install-libs".
8258 E2fsprogs 1.03 (March 27, 1996)
8259 ===============================
8261 Change the m68k bit numbering for bitmasks to match the bit numbering
8262 used by all other ext2 implementations. (This change was requested by
8263 the m68k kernel development team.)
8265 Support (in-development) filesystem format revision which supports
8266 (among other things) dynamically sized inodes.
8268 Fixed a bug in the ext2 library so that an intelligent error is
8269 returned if mke2fs is run with a ridiculously small number of blocks
8272 Fixed a bug in the ext2 library which required that the device be
8273 openable in read/write mode in order to determine its size. This
8274 caused e2fsck -n to require read/write access when it was not
8275 previously necessary.
8277 Fixed a bug in e2fsck which casued it to occasionally fail the test
8278 suite depending on which version of the floating point library it was
8281 Fixed a bug in e2fsck so that it now halts with a fatal error when
8282 certain superblock consistency checks fail. Previously it continued
8283 running e2fsck, with some potential confusing/damaging consequences.
8285 Added new flag to fsck which allows the root to be checked in parallel
8286 with other filesytems. This is not the safest thing in the world to
8287 do, but some system administrators really wanted it.
8289 Fixed -Wall flames in lib/ss.
8292 E2fsprogs 1.02 (January 16, 1996)
8293 =================================
8295 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
8297 Change e2fsck to print statistics of how many non-contiguous files are
8298 on the system. Note that a file which is larger than 8k blocks, it is
8299 guaranteed to be non-contiguous.
8301 In mke2fs, print a warning message if a user tries to format a whole
8302 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
8303 whole disk, the -F (force) option forces mke2fs to format a whole disk
8306 Fix a bug in fsck where in some cases it might start checking
8307 partitions in the next pass before it finishes checking partitions in
8308 the current pass. This still won't cause two partitions on the same
8309 disk will be checked, so it's rarely a problem in real life.
8311 Patch lsattr so that it won't hang when checking a named pipe.
8313 Minor compilation fixes:
8314 * Fix the order of libraries that were linked in debugfs.
8315 * Allow the sources to be compiled with -ansi turned on.
