1 E2fsprogs 1.42.13 (May 17, 2015)
2 ================================
4 Fixed a potential buffer overflow while closing a file system in
5 libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
7 Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
8 (Addresses Debian Bug: #760275)
10 Fixed a deadlock which occurs when using systemd and e2fsck.conf's
11 logging feature. (Addresses Debian Bug: #775234)
13 Fixed a bug which could cause programs using libext2's inode table
14 scanning functions from crashing on certain corrupted file systems.
15 (Addresses Debian Bug: #773795)
17 Fixed dumpe2fs so it won't crash if the user doesn't specify a block
18 device (file system). (Addresses Debian Bug: #764293)
20 Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
21 will report the correct directory inode containing the inconsistency.
23 If e2fsck fails to grow the dir_info structure due realloc(3) not
24 having enough memory, it will now fail with explanatory message
25 instead of staggering on failing with a confusing internal error
28 The tune2fs program will zero out the superblock journal backup
29 information when removing a journal from a file system.
31 The mke2fs program now enables the large_file feature by default.
33 Fixed a bug which could cause badblocks to crash if there are millions
34 and millions of bad blocks.
36 Fixed some use-after-free bug in resize2fs and e2fsck.
38 Fixed a memory leak in tune2fs.
40 Fixed some bigendian bugs that had crept into both indirect and extent
41 handling inside libext2fs.
43 Updated/fixed various man pages.
45 Update Esperanto, German, and Spanish translations. Added Danish
51 Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
53 Clean up some build system problems (build failures with various
54 configure options, fix Posix portability issues, etc.)
56 The functions ext2fs_inode_alloc_stats[2]() and
57 ext2fs_block_alloc_stats[2]() now check the inode and block numbers
58 passed to them, to avoid crashes caused by buggy callers.
60 The libext2fs directory iterator will now check for an invalid
61 directory entry length instead of possibly walking off the end of the
65 E2fsprogs 1.42.12 (August 25, 2014)
66 ===================================
68 Fix various e2fsck bugs when trying to repair bigalloc file systems.
70 E2fsck can now repair a file system with an overly large
71 s_first_meta_bg field, which had previously caused all e2fsprogs
72 programs to crash when trying to open such a file system.
74 Fix e2fsck so that it can correctly fix a number of rare file system
75 corruptions that were discovered when using a file system fuzzer.
77 Fix e2fsck so it does not try to write back block group descriptors if
78 they have not been modified.
80 Mke2fs program will now place metadata blocks in the last flex_bg so
81 they are contiguous. This reduces free space fragmentation in a
82 freshly created file system, as well as allowing mke2fs commands which
83 request extremely large flex_bg size to succeed.
85 Mke2fs now creates hugefiles more efficiently (with fewer extent tree
88 Fix a 32/64-bit overflow bug that could cause resize2fs to loop
89 forever. (Addresses-Launchpad-Bug: #1321958)
91 The resize2fs program will now use much less memory when resizing very
94 Fix a bug which could cause resize2fs to get confused and produce a
95 corrupted file system when shrinking a file system that had been
96 previously expanded and converted to use the meta_bg file system
97 format, but which no longer needs to use the meta_bg file system
98 format any longer. This typically happened with large (> 16TB) file
99 systems. (Addresses Debian Bug: #756922)
101 The e4defrag program will now defrag backwards-allocated files.
103 Fix tune2fs updating UUID's when manipulating file systems with
104 external journals (both the file system and journal UUID).
106 Fix tune2fs so it can remove an external journal for file systems with
109 Add a new debugfs command, "inode_dump", which prints the inode in hex
112 The debugfs's "set_inode_field" will now automatically allocate blocks
113 for indirect blocks and extent tree blocks.
115 Fix debugfs's "set_inode_field" so can properly handle
116 "block[IND|DIND|TIND]".
118 The debugfs "rdump" command will now take multiple source arguments.
120 Fixed a double close(2) bug in "rdump" and "rdump -p".
122 Fix debugfs's argument parsing for the freefrag command.
124 Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
125 (Addresses Launchpad Bug: #1356496)
127 Clarified messages that were confusing users in debugfs, e2fsck,
128 mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
131 Dumpe2fs will now complain if extra arguments are given to it.
132 (Addresses Debian Bug: #758074)
134 Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
136 Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian, and
137 Vietnamese translations.
142 The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
143 number of system calls issued.
145 Fixed profiled build.
147 The libext2fs library will now more efficiently split an extent tree
148 index block when appending to an end of a file.
150 Fixed free block accounting for 64-bit file systems.
152 Add a new function ext2s_inode_size_set() which takes care of all of
153 the required feature flag modifications.
155 The regression tests no longer require the presence of the md5sum
158 Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
161 Fix various Coverity warnings (#1225003, #1229243, #1252003)
164 E2fsprogs 1.42.11 (July 9, 2014)
165 ================================
167 Add support so that mke2fs can create hugefiles so that they are
168 aligned relative to the beginning of the disk, instead of relative to
169 the beginning of the partition, using the mke2fs.conf configuration
170 parameter "hugefiles_align_disk".
172 Fix a bug which causes e2fsck to abort a journal replay on a file
173 system with bigalloc enabled. (Addresses Debian Bug: #744953)
175 Add sanity checks so that mke2fs will refuse insanely large flex_bg
176 counts specified by the -G option. Insanely large flex_bg sizes can
177 result in a file system which can't be unmounted, or with extremely
178 pessimal metadata layouts.
180 The mke2fs program will provide a better metadata layout for
181 moderately large (but believable) flex_bg counts, such as 133,072.
183 The mke2fs progam will also check the kernel version number to
184 determine whether the lazy_itable_init option is supported, so that
185 lazy inode table initialization can be used even if the ext4 is
186 compiled as a module which isn't loaded at the time that mke2fs is
189 Add description of ext4's mount options to the ext4 section 5 man
192 Improve the chattr man page and clean up the chattr usage message.
194 E2fsck will now automatically fix a last mount time or last write time
195 which is in the future in preen mode, instead of aborting the fsck
198 Mke2fs will now check the file system revision number requested by the
199 command line, and reject it if it is too large. A file system with an
200 unsupported revision number will not be accepted by any of the other
201 file system tools, and this command line option is rarely used, so
202 let's try to help the user not shoot their own foot off.
204 The debugfs progam can now set the error count and associated
205 first_error and last_error fields in the superblock using the
206 set_super_value command.
208 Resize2fs will not try to calculate the minimum size of a file system
209 if it contains errors. Otherwise a very badly corrupted file system
210 image can cause the minimum size calculation to loop forwever. Since
211 resize2fs will not allow a file system marked as containing errors to
212 be resized. It's pointless to calculate the minimum size, so just
215 Fixed a typo in one of mke2fs's error message.
217 If filefrag runs into an error, it will continue processing the rest
218 of the files specified on thec ommand line, but then exit with an
221 Filefrag now prints some additional new flags (such as
222 FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
224 Fixed support in filefrag for files with > 2**32 blocks on 32-bit
227 Fixed a file descriptor leak in debugfs when copying files.
229 Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
230 to create file systems larger than 2GB on 32-bit platforms.
231 (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
233 Add Esparanto and Ukrainian translations, and update Czech, Dutch,
234 French, German, Italian, Polish, Sweedish, and Vietnamese
237 Fixed various compiler warnings.
243 The gcc "-checker" option has been long deprecated, so remove support
244 from e2fsprogs. It was causing a few people to be confused when they
245 tried enabling the configure option.
247 Update to the latest version of the config.status and config.rpath
248 files, as well as newer versions of the autoconf files in aclocal.m4.
249 Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
250 people who want to use autoreconf to do so.
252 Make the use of strptime() function in debugfs to be more portable to
253 fix regression test failures for FreeBSD and MacOS.
255 A few miscellaneous changes designed to make life easier for
258 Fix the f_quota test and some Makefile dependencies if quota support
261 Fix cross-compilation support, which got broken in 1.42.10.
262 (Addresses Debian Bug: #753375)
264 Delete lib/ext2_types.h on a make clean, and build it as necessary.
266 Add a debug program used for libext2fs unit tests.
268 Clean up the tests so that it avoids using GNU-specific behaviour in
269 mktemp. Make sure the temporary files are cleaned up if the tests are
272 Add a new ext2fs_close_free() helper function which automatically
273 takes care of freeing the ext2_filsys structure even if ext2fs_close()
277 E2fsprogs 1.42.10 (May 18, 2014)
278 ================================
280 Mke2fs now creates file systems in regular files (which is very often
281 used when maintaining virtual machine images) without requiring the
282 user to use the force option. In addition, the mke2fs output has been
283 made much less verbose and only displays information that users will
284 be more likely to find useful by default.
286 Mke2fs now will ask the user to confirm that they want to continue
287 before wiping out a pre-existing file system, partition table, or LVM
290 Mke2fs now has the ability to create file systems where all the
291 metadata is located at the very beginning of the device. This can be
292 useful for flash devices which have SLC flash at the beginning of the
293 disk, for FAT compatibility, for example. As part of this, mke2fs and
294 tune2fs can control the location of the data blocks used by the
295 journal inode. In addition, the new sparse_super2 feature allows for
296 even fewer (anywhere from zero to two) backup superblocks.
298 Mke2fs now uses much less CPU when allocating the blocks used for very
301 Mke2fs can now support creating a file system at an offset. This can
302 be useful when creating a disk image for virtual machines (Addresses
305 Previously, e2fsck had a number of very serious bugs when checking a
306 file system wich used the new the quota file system option (where the
307 quota inodes were stored in hidden inodes) and the quota inode was
308 inconsistent with the actual usage data. This problem was documented
309 in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
310 been fixed in 1.42.10, so the quota should be safe to use with
313 Fixed in a bug in resize2fs which could cause shrink operation fail in
314 the unlikely situation when the inode table needs to be moved to a
315 location before the current location.
317 Resize2fs now has a much more accurate (and less conservative)
318 estimation of how far the file system can be shrunk. This allows a
319 mostly empty filesystem which is a few terabytes, to be shrunk to a
320 few megabytes in a single resize2fs -M operation.
322 E2fsck will now force a full file system check if there are any file
323 system inconsistencies detected in the super block.
325 The filefrag program will now display hte shared extent flag, which is
326 used by file systems such as btrfs.
328 If the number of inodes in the file systems is larger than the time
329 that file sytem was created (as measured by the number of seconds
330 since January 1, 1970) e2fsck would print a scary (but otherwise
331 harmless) warning of file system corruption for each inode in the
332 orphan list. This false positive has been fixed.
334 The e4defrag program has been fixed so it will no longer refuse with
335 filesystem with the 64-bit or the bigalloc feature enabled.
337 The logsave progam will print a much less scary message which could
338 lead users to believe something has gone very wrong with e2fsck exits
339 with a non-zero exit status (since this is normal after e2fsck has
340 automatically fixed a file system corruption during a preen
341 operation). (Addresses Debian Bug: #468821)
343 When creating a file system which is larger than 16TB, the
344 resize_inode option must be disabled -- since the resize_inode simply
345 doesn't support reserving metadata block numbers which is larger than
346 32 bits. The mke2fs program does this automatically if the file
347 system size is determined automatically. It will now also do this if
348 the file size is specified explicitly.
350 Fixed bugs associated with resize2fs and shrinking bigalloc file
353 The e2fsck program will no longer try to add a UUID on a mounted file
354 system with checksums enabled, since this could leave the file system
357 Tune2fs will allow the removal of an external journal from file system
358 which is marked as needing the journal replayed when the force ("-f")
359 option is given twice. (Addresses Debian Bug: #559301)
361 Tune2fs will no longer support enabling sparse_super if the meta_bg
362 file system feature is enabled, since it could result in data loss.
363 In practice, all modern file systems have sparse_super is enabled, so
364 it's not worth trying to change how tune2fs handles enabling the
365 sparse_super feature.
367 Fixed support for 1k block file systems with the meta_bg feature.
369 When the superblock is corrupt, e2fsck can't figure out the location
370 of the alternate superblock. Unfortunately, the routine that
371 calculates the location of the alternate superblock uses 8193 if it
372 can't figure this out, so the message printed by e2fsck always
373 suggests using "e2fsck -b 8193". This message has been fixed to
374 suggest both the superblock location of 8193 and and 32768.
375 (Addresses Debian Bug: #719185)
377 The lookback mount detection code that was introduced in 1.42.9 wasn't
378 actually compiled in due to an autoconf oops, so it's fixed now in
379 1.42.10. (Addresses Debian Bug: #497984)
381 A bug introduced in 1.42.9 would cause debugfs to print two error
382 messages if it found an error while parsing a user-supplied block
383 number. This has been fixed in 1.42.10.
385 Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
386 Vietnamese translations. (Addresses Debian Bug: #703048)
388 Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
391 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
397 Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
399 Allow the location of pkg-config files to be specified independent of
400 the libdir location via a makefile variable.
402 Fixed parse-types.sh not to complain when cross-compiling and the
403 sizes of types are different between the target architecture and the
404 architecture of the build system
406 Allow the regression test suite to work correctly on systems which do
407 not have the "truncate" or "mksawp" programs.
409 Allow e2fsck to build correctly on systems (such as Android) that do
410 not have the signal.h file.
412 E2fsprogs now has code coverage testing which can be enbled using
413 "configure --enable-gcov".
415 The libe2p.h header file can now be used included by C++ programs.
417 The profile/config file used by e2fsck and mke2fs will interpret
418 numbers with a leading 0 character to mean that they should be
419 interpreted as an octal integer.
421 The extent handling functions in libext2fs have been improved so they
422 have proper rollback when there is an error splitting an extent. Also
423 fix a number of bugs when punching holes in files, and fix an
424 off-by-one bug when inserting an extent into an empty inode.
426 The libext2fs library now handles the support of BLOCK_UNINIT by
427 clearing the portion of block bitmap when it is loaded, instead of
428 when it is used. This reduces the chances of bugs, and and simplifies
429 the code. It also means that debugfs will properly show that blocks
430 in uninitialized block groups as being unused when using the testb
433 The e4defrag program will try to use fadvise64 or posix_fadvise64() if
434 it is present, which allows 64-bit offsets on 32-bit systems.
437 E2fsprogs 1.42.9 (December 28, 2013)
438 ====================================
440 Mke2fs will detect an attempt to create a file system on a loop
441 mounted file and complain without the -FF option. Also fixed mke2fs
442 so it allows the creation of a file system on a mounted device with
443 two -F options, as documented in the man page, instead of three -F
446 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
447 libext2fs to correctly handle bigalloc and 64-bit file systems. There
448 were many corner cases that had not been noticed in previous uses of
449 these file systems, since they are not as common. Some of the bugs
450 could cause file system corruption or data loss, so users of 64-bit or
451 bigalloc file systems are strongly urged to upgrade to e2fsprogs
454 The tune2fs program will now not allow changing the uuid on a mounted
455 file system which has the uninit_bg feature enabled. This avoids a
456 nasty race where the kernel and tune2fs are both retrying rewrite the
457 group descriptors at the same time, with different ideas about what
460 When e2fsck is rehashing an extent-mapped directory, it's possible
461 (although very rare) that an extent block will need to be allocated;
462 fix e2fsck to make sure that the block gets marked as used.
464 Mke2fs will now properly set the LARGE_FILE feature when creating a
465 journal >= 2GB --- which can happen when using 64k block size.
467 Fixed debugfs so that its freei command will correctly handle a request
468 to free a range of consecutive inodes.
470 Fixed 2fsck so it will not erroneously complain that an external journal
471 is invalid if it is exactly 2**32 blocks.
473 Fixed e2fsck so it won't try checking for, and adding, a missing
474 lost+found directory when running in read-only mode.
476 Fixed e2image to avoid some buffer overruns which would cause it to when
477 creating a "standard (non-raw, non-qcow2) image file. Standard
478 e2image files are actually very rarely used, so we didn't notice when
479 the changes to enable the qcow2 format broke this e2image mode.
481 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
482 on the resize_inode feature when the meta_bg feature is set, since
483 these two features can not be set at the same time.
485 Fixed tune2fs so that when it disables the quota feature, it updates all
486 of the backup superblocks.
488 Fixed dumpe2fs that would cause it to abort when run using an image file
489 when trying to print the journal information (which is not present in
490 an e2image created image file).
492 Fixed a potential integer overflow in e2reefrag.
493 (Addresses-Debian-Bug: #718205)
495 Enhance debugfs so that when copying a sparse file from a native file
496 system into the file system image using the "write" command, it will
497 create a sparse file into the destination file system.
499 Enhanced debugfs so it can support a command line which is up to 8k
502 E2image will refuse (unless the -f option is specified to force the
503 issue) to create a raw or qcow image using a mounted file system,
504 unless the -f option is specified to force the issue.
506 E2image has been optimized for using it to efficiently copy a file
507 system by only copying the allocated blocks, by using the options -ra.
508 New options (-o and -O) have been added so that a source and
509 destination offset can be given. The -p option will print progress
510 information so the user will know how far along the copy is going.
511 And finally, the new option -c is useful for updating a file system on
512 an SSD, by avoiding unnecessary writes. E2image can also shift a file
513 system image by doing an in place move.
515 Fix a regression introduced in 1.42.8 which would cause e2fsck to
516 erroneously report uninitialized extents past the EOF (as determined by
517 i_size) to be invalid.
519 Fixed resize2fs so under a corner case when an inode has a complex
520 extent tree, it will not corrupt an interior node in the extent tree.
522 Fixed resize2fs which would sometimes corrupt a file system when
523 shrinking a file system to a minimum size using resize2fs -M.
524 (Addresses Debian Bug: #660793)
526 Fixed resize2fs so that it will relocate inode table blocks if this
527 becomes necessary when shrinking the file system.
529 Fixed resize2fs and e2fsck so they will not crash when hit a failure
530 while operating on a file system with the MMP feature enabled.
532 Fixed a bug in debugfs which caused it create an invalid inode when
533 trying to write a zero-length file.
535 E2fsck will no longer crash if it tries to delete an invalid
536 extent-mapped symlink.
538 E2fsck will no longer crash if it comes across an directory which is
539 larger than 2GB (which is not allowed in valid file systems).
541 Fixed debugfs's help texts to fully document all options and otherwise
544 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
547 Fixed various Debian Packaging Issues (#698879, #721365)
553 Fix sparse, gcc -Wall and clang nits.
555 Update config.{guess,sub} to the latest version
557 Fixed various memory and file descriptor leaks on various error paths,
558 as well as some missing error return checks, which were found using
561 Run sparse against source files when building e2fsprogs with 'make
562 C=1'. If instead C=2, it configures basic ext2 types for bitwise
563 checking with sparse, which can help find the (many many) spots where
564 conversion errors are (possibly) happening.
566 Allow the regression test to be run in chrooted environments where
567 /etc/mtab might be missing.
569 The ext2fs_punch() function, which was introduced in 1.42, was broken
570 in many ways, but this was never noticed since it wasn't used for
571 anything significant. Some of the bugs include failing when trying to
572 punch a completely sparse file, failing when punching an extent-mapped
573 inode when the starting block was at the beginning of the inode, and
574 not being able to punch a single block (where start_blk == end_block).
575 It also didn't handle being passed an invalid, too-large ending block
576 number, and didn't handle properly terminate at the right place when
577 operating on an indirect-mapped inode.
579 Fixed some minor typo's in the error catalog for libext2fs.
581 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
582 setting the file size, to zero the rest of the block to the end of the
583 file, so that if an ext4 FUSE driver tries to extended the file, that
584 we don't avoid stale data from being returned.
586 Fixed ext2fs_bmap() to disallow clients from trying to map or set
587 logical blocks which are larger than what an extent-mapped or indirect
588 block-mapped inode can allow.
590 If debugfs (or some userspace program using libext2fs) creates a file
591 which is larger than 2GB, make sure the large_file feature flag gets
594 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
595 directory which are large enough, the directory entry could get
596 inserted more than once in the directory.
598 If quota support is disabled (which is the default), make sure that
599 all traces of the quota support is removed from usage messages, man
600 pages, and tune2fs must not be able to enable the quota file system
601 feature. (Addresses Red Hat Bugzilla: #1010709)
603 The ext2fs_file_write() now updates i_size on a successful write,
604 instead of only updating i_size wen the file is closed via
607 Added a shell script, populate-extfs.sh which uses debugfs to populate
608 an ext2/3/4 file system image from a given directory. It is similar
609 to the genext2fs program, but it supports ext3 and ext4 file system.
611 Add changes to the libext2fs library to support block group
612 descriptors larger than 64 bytes (for future compatibility).
614 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
615 leave an extra block in the file when truncating the file down to
618 The html version info pages are now built using makeinfo --html
619 instead of the unmaintained and now-obsolete texi2html program.
622 E2fsprogs 1.42.8 (June 20, 2013)
623 ================================
625 As a part of mke2fs's option parsing cleanup, the use of the -R option
626 will give a warning that it is depreated (it has been so documented

629 Mke2fs will not give warnings about the bigalloc and quota options in

635 Debugfs was erroneously giving spurious error messages for certain
636 extent_inode subcommands which take arguments (split_node,
637 replace_node, and insert_node). This has been fixed.
639 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
640 other programs is used by mke2fs.
642 Change mke2fs so that it does not set the root directory to the real
643 uid/gid of the mke2fs process. Add the extended option root_owner to
644 override this behavior.
646 Fix resize2fs when shrinking file systems to make sure that bitmap
647 blocks aren't left outside the bounds of the shrunken file system.
648 This could happen with flex_bg file systems that were grown using
649 the old online resizing algorithm.
651 E2fsck will now detect and repair corrupted extent trees which contain
652 invalid extents at the end of the extent tree leaf block.
654 E2fsck will now longer complain about zero length extended attribute
657 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
660 Add safety check so tune2fs will not attempt to set the inode size to
661 be larger than the block size.
663 Fix e2fsck so it can check a read-only root file system with an
664 external journal. (Addresses Debian Bug: #707030
666 Fix off-line resizing of file systems with flex_bg && !resize_inode

690 SEEK_CUR is used with large files.
692 The ext2fs_read_inode_full() function will no longer use
693 fs->read_inode() if the caller has requested more than the base 128

704 E2fsprogs 1.42.7 (January 21, 2013)
705 ===================================
707 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
708 quota features are still under development. For more information
710 * https://ext4.wiki.kernel.org/index.php/Bigalloc
711 * https://ext4.wiki.kernel.org/index.php/Quota
713 Add some new options to filefrag from Lustre's patches to e2fsprogs:
714 * add -k option to print extents in kB-sized units (like df -k)
715 * add -b {blocksize} to print extents in blocksize units
716 * add -e option to print extent format, even when FIBMAP is used
717 * add -X option to print extents in hexadecimal format
719 Fix resize2fs so that it can handle off-line resizes of file systems
720 with the flex_bg feature but without a resize_inode (or if we run out
721 of reserved gdt blocks). This also fixes a problem where if the user
722 creates a filesystem with a restricted number of reserved gdt blocks,
723 an off-line resize which grows the file system could potentially
724 result in file system corruption.
726 Fix a resize2fs bug which could cause it to corrupt bigalloc file
727 systems when doing an off-line resize.
729 Further optimize resize2fs so it doesn't use quite as much CPU when
730 resizing very large file systems.
732 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
733 possibly corrupt the file system while resizing 64-bit file systems.
735 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
736 mke2fs crash due to a divide-by-zero if the 64bit file system feature
739 Add better error checking to mke2fs to check for invalid parameters
740 when creating bigalloc file system.
742 When creating bigalloc filesystems, the -g option to mke2fs will now
743 specify the number of clusters per block group.
745 Add to debugfs the functionality to corrupt a specific file system
746 block via the "zap_block" command.
748 Add to debugfs the functionality to print out a hex dump of a block in
749 the file system via the "block_dump" command.
751 Add to debugfs the functionality to manipulate the extent tree
752 directly via the "extent_open" command.
754 Fixed debugfs's mknod command so that it updates the block group
757 Fix e2fsck so it can detect and fix inconsistencies in the interior
758 nodes of an inode's extent tree.
760 Fix a potential memory corruption failure in e2fsck's error path if
761 the call to ext2fs_open2() fails.
763 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
764 resulting file name for the log file is longer than 100 bytes, that it
765 properly handles this situation instead of crashing.
767 E2fsck will now report the amount of memory that it attempted to
768 allocate when a memory allocation request fails, to make it easier to
769 track down the problem.
771 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
774 E2image can now include all data blocks in the e2image output file
775 when the user specifies the -a option.
777 If e2fsprogs is compiled without --enable-quota, make sure that
778 tune2fs can not turn on the feature for new-style quota support, since
779 afterwards, none of the e2fsprogs tools will be willing to touch that
782 Optimize e2fsck's so that it uses much less CPU for large file
783 systems. This can result in significant speedups, especially on
784 CPU-constrained systems. This was primarily done by optimizing
785 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
787 Fix debugfs's htree command so that all its messages are sent through
790 Fixed debugfs's "dump_file" and "cat" functions work correctly
791 on file systems whose block size is greater than 8k.
793 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
794 less memory. (Addresses Google Bug: 7269948)
796 Update the spd_readdir.c file in the contrib directory to include some
797 additions which were made in 2008 that didn't get folded into the
798 version which we checked into the e2fsprogs source tree. These
799 enhancements include thread safety, support for readdir64_r(), and
800 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
802 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
805 Add a command to debugfs to create symlinks.
807 Document the bigalloc feature in the mke2fs man page. (Addresses
816 Fix a spelling typo in the libext2fs texinfo documentation.
818 Change the output from "make check" so that tools such as emacs's "M-x
819 compile" does not mistake the output as containing a compiler error.
821 Export two new functions from libext2fs: ext2fs_extent_node_split()
822 and ext2fs_extent_goto2().
824 The ext2fs_extents_fix_parents() was fixed so it does not modify the
825 location of the extent handle if its current location is at an
826 interior node, rather than a leaf node of an inode's extent tree.
828 Add a regression test to assure that e2fsck can correctly fix an
829 inconsistent interior node in an inode's extent tree.
831 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
832 correctly support bigalloc file systems which use store block usage
833 information in units of clusters.
835 Fixed the help text in the configure script for --enable-quota.
837 The m68k-specific bitops code has been removed since they were
838 incorrectly treating bit numbers with the high bit set as signed
839 integers. Furthermore, modern compilers do a good enough job
840 optimizing the generic code there is no point in having the m68k
841 specific asm statements.
843 Fixed how we link the test programs so they always use the static
844 libraries, so that we test using the libraries which we have just
847 Update config.guess and config.sub to the latest versions from the GNU
850 Fixed the com_err.texinfo file so that it can produce a valid
851 postscript/pdf printed output.
853 Add a regression test which checks debugfs's ability to create
854 symlinks, named FIFO's, and device nodes.
856 Add a function ext2fs_symlink(), which creates symlinks to the
859 Add debugging code so we can test old kernel interfaces for online
860 resize to resize2fs. This backwards compatibility checking is keyed
861 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
862 test the functionality of the kernel's older resize ioctls without
863 needing to install an old version of resize2fs, and to also test a
864 modern resize2fs's ability to work with older kernels without having
865 to install an older version of the kernel.
868 E2fsprogs 1.42.6 (September 21, 2012)
869 =====================================
871 When mke2fs creates file systems with lazy itable initialization, the
872 progress updates for writing the inode table happens so quickly that
873 on a serial console, the time to write the progress updates can be the
874 bottleneck. So mke2fs will now only update its progress indicators
877 Resize2fs will skip initializing the inode tables if the kernel
878 supports lazy_itable_init, which speeds up growing off-line growth of
879 uninit_bg file systems significantly. Resize2fs will now also
880 correctly set the itable_unused field in the block group descriptor to
881 speed up the first e2fsck after the file system is grown.
883 Resize2fs has been fixed so that on-line resizing of meta_bg file
884 systems work correctly. This is needed to grow file system which are
887 Resize2fs will now correctly handle resizing file systems to 16TB on
888 32-bit file systems when "16TB" is specified on the command line.
890 Fix mke2fs so that it will be careful to set the reserved blocks ratio
891 larger than 50%; this can happen when creating small file systems and
892 when the last block group is dropped because there are not enough
893 blocks to support the metadata blocks in the last block group.
895 Fixed spelling mistake in debugfs's help message.
897 Fixed a potential seg fault in e2fsck when there is an I/O error while
898 reading the superblock.
900 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
902 Updated/fixed various man pages. (Addresses Sourceforge Bug:
908 The configure option --enable-relative-symlink was broken so that it

913 Fixed a regression introduced in 1.42.5 so the link order for
914 e2fsprogs' libraries will be correct for both static and shared
915 linking. (Addresses Sourceforge Bug: #3554345)

927 E2fsprogs 1.42.5 (July 29, 2012)
928 ================================
930 Fixed a bug with mke2fs where if there is only 8 inodes per block
931 group, the calculation of the number of uninitialized inodes in the
932 first block group would go negative. This resulted in "mke2fs -N 256
933 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
934 would run out of space. (Addresses Sourceforge Bug: #3528892)
936 Fixed a bug in how e2fsck would uniquify directory entry names.
937 (AddressesSourceforge Bug: #3540545)
939 Previously, e2fsck would only allow a mounted file system to be
940 checked if it was the root file system and it was mounted read-only.
941 Now it will allow any file system mounted read-only to be checked if
942 the -f option is specified. This makes it easier to test how e2fsck
943 handles checking file systems which are mounted without having to test
944 on the root file system.
946 Fixed a problem if e2fsck where if the root file system is mounted
947 read-only, e2fsck would not clear an error indication in the journal
948 superblock. Combined with a kernel bug, this would cause the e2fsck
949 to check the file system after every single boot.
951 The e4defrag program can now handle device symlinks, such as
952 /dev/mapper/testvg-testlv, instead of insisting on a less
953 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
956 Fixed filefrag so it will not crash with a segfault on files from a
957 virtual file system such as /proc. (e.g., "filefrag
960 Fixed filefrag so that it correctly reports the number of extents.
961 (Addresses Red Hat Bugzilla: #840848)
963 Fixed a file descriptor leak in logsave which could cause it to hang.
964 (Addresses Debian Bug: #682592)
966 Fixed e2fsck so that the file system is marked as containing an error
967 if the user chooses not to fix the quota usage information.
969 Fixed tune2fs so that it correctly removes the quota feature when the
970 last quota inode is removed.
972 Fix tune2fs so that after removing a quota inode, the block bitmap is
973 updated; otherwise, e2fsck would complain after running 'tune2fs -O
976 Fix tune2fs so that when converting a file system from using legacy
977 quota files to the new quota file system feature with hidden quota
978 files, the accounting for these files is handled correctly so that
979 e2fsck doesn't complain.
981 Improved e2fsck's verbose reporting statistics, and allow the more
982 verbose reporting to be enabled via /etc/e2fsck.conf.
984 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
986 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
992 Fixed portability problems on other operating systems (e.g., Hurd and
993 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
995 Make sure that shared libraries link with the shared libraries built
996 in the build tree, instead of the system provided libraries.
997 Previously, libraries and executables were linked with the system
998 libraries if present, and possibly using static archives instead of
999 shared libraries. This was also problematic since if libext2fs.so is
1000 linked with a static libcom_err.a from system, the build system would
1001 attempt to link without -lpthread. (Addresses Sourceforge Bug:
1005 E2fsprogs 1.42.4 (June 12, 2012)
1006 ================================
1008 Fixed more 64-bit block number bugs (which could end up corrupting
1009 file systems!) in e2fsck, debugfs, and libext2fs.
1011 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
1012 not properly propagating the journal's s_errno field to the superblock
1013 field; it was not checking this field if the journal had already been
1014 replayed, and if the journal *was* being replayed, the "error bit"
1015 wasn't getting flushed out to disk.
1017 Fixed a false positive complaint by e2fsck if all of the extents in
1018 the last extent tree block are uninitalized and located after the end
1019 of the file as defined by i_size.
1021 The dumpe2fs will now display the journal's s_errno field if it is
1022 non-zero, and it will also display the journal's 64-bit feature flag
1025 Fix e2fsck so that it always opens the device file in exclusive mode
1026 when it might need to modify the file system, and never if the -n
1027 option is specified. (Previously, there were a few corner cases where
1028 it might get things wrong in either direction.)
1030 E2fsck now correctly truncates or deallocates extent-mapped inodes on
1031 the orphan list. The root cause was a bug in libext2fs's block
1032 iterator which could end up skipping an extent when the last block in
1033 an extent is removed, causing the current extent to be removed from
1036 E2fsck now correctly sets the global free block and inode counts when
1037 truncating or removing inodes on the orphan list in preen mode.
1038 Previously, it would leave these values would be set incorrectly,
1039 which is largely a cosmetic issue since the kernel no longer pays
1040 attention to those fields, but it can cause spurious complaints in
1041 subsequent e2fsck runs.
1043 Fix i_blocks accounting when the libext2fs library needs to add or
1044 remove an extent tree block on bigalloc file systems.
1046 The lsattr and chattr programs now support the No_COW flag for the
1049 Debugfs now interprets date strings of the form @ddd as ddd seconds
1050 after the beginning of the epoch. This is handy when setting an inode
1051 number into the d_time field when debugging orphan list handling.
1053 Fix a precedence bug with built-in quota support which might result in
1054 e2fsck paying attention to the quota inode field even if the built-in
1055 quota feature flag is not set. Fortunately, in practice that
1056 superblock field should be zero for non-built-in quota file systems,
1057 so it's unlikely this bug would have caused problems.
1059 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
1065 The regression test suite can now run the integration tests in the
1066 tests directory in parallel, via "make -jN check".
1068 Add new test, f_zero_extent_length which tests e2fsck's handling of
1069 the case where all of the extents in the last extent tree block are
1070 uninitialized extents after i_size.
1072 Add a new test, f_jnl_errno, which checks handling of an error
1073 indication set in the journal superblock.
1075 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
1076 of a 64-bit journal.
1078 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
1079 tests e2fsck's handling of orphan inodes in preen mode, and truncation
1080 of extent inodes on the orphan list.
1082 Fixed more OS X portability issues.
1085 E2fsprogs 1.42.3 (May 14, 2012)
1086 ===============================
1088 Fix a bug in the Unix I/O manager which could cause corruption of file
1089 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
1090 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
1091 dumpe2fs to incorrectly display block numbers > 32-bits.
1093 Improve the support for integrated quota files (where quota is a first
1094 class supported feature using hidden files in the ext4 file system).
1095 Previously the quota file was getting rewritten even when it was not
1096 necessary, and e2fsck would erroneously try to hide quota files which
1097 were already hidden.
1099 Quiet complaints in e2fsck when the total free blocks or inodes are
1100 incorrect in the superblock after an system crash, since we don't
1101 update nor depend on the superblock summaries at each commit boundary.
1103 Fixed a regression introduced in 1.42.2 which would cause applications
1104 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
1105 would were still using the legacy 32-bit bitmaps) to crash. This was
1106 due to missing 32-bit compat code in side the function
1107 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
1110 Fix a bug which would cause mke2fs to fail creating the journal if
1111 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
1114 Updated/fixed various man pages.
1116 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
1119 Fixed various Debian Packaging issues.
1125 Change the nonsensically wrong types in the function signature of the
1126 inline function ext2fs_find_first_zero_block_bitmap2(). This was
1127 caused by a cut and paste error; fortunately no code in e2fsprogs used
1128 this inline function, and there are any users of this functions
1129 outside of e2fsprogs.
1131 Add support for systems which have valloc(), but which do have
1132 posix_memalign() nor memalign() (such as MacOS 10.5).
1134 Refactor and clean up the allocation of aligned buffers for Direct I/O
1135 support. Previously some allocations were requesting a greater
1136 alignment factor that what was strictly necessary. Also optimize
1137 reading and writing bitmaps using Direct I/O when the size of the
1138 bitmap did not fully cover the file system blocksize.
1140 Reserve the codepoints for the INCOMPAT features LARGEDATA and
1143 Improved the regression test suite by adding some new integration
1144 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
1145 jbd2 format, as well as f_eofblocks which tests the new handling of
1146 uninitialized and initialized blocks beyond i_size. Also add a new
1147 unit test which verifies 32-bit bitmaps support and the new
1148 find_first_zero primitives.
1150 Add a few dependencies to fix parallel (make -j) builds.
1152 Removed bash'isms which were breaking the regression test suite on
1153 systems where /bin/sh is not bash.
1155 The config.guess and config.sub have been updated to the 2012-02-10
1158 Fix a portability problem caused by assuming the present of mntent.h
1159 means that setmntent() exists. Instead, explicitly test for this in
1160 the configure script.
1162 If the sys/signal.h header file does not exist, don't try to include
1163 it, since it's not available on all systems.
1165 Add support for systems that do not support getpwuid_r()
1167 The configure script now supports a new option,
1168 --enable-relative-symlinks, which will install relative symlinks for
1169 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
1171 When building BSD shared libraries make sure the LDFLAGS variable is
1172 passed to the linker. Fixing this allows, for example, e2fsprogs to
1173 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
1176 Fix gcc -Wall nitpicks
1179 E2fsprogs 1.42.2 (March 27, 2012)
1180 =================================
1182 The resize2fs program uses much less CPU and is much faster for very
1183 large file systems. (Addresses Debian Bug: #663237)
1185 The seti and freei commands in debugfs can now take an optional length
1186 argument to set and clear a contiguous range of inodes.
1188 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
1189 plan to remove support for it from the kernel file system driver. It
1190 really wasn't very useful and was causing more problems than it
1191 solves. Since e2fsck will complain if inodes that should have
1192 EOFBLOCKS_FL do not have the flag set, we are going to remove this
1193 check from e2fsprogs first, and then only remove the flag from the
1196 The mke2fs program can now use direct I/O via "mke2fs -D". This will
1197 slow down the mke2fs, but it makes it more polite on a loaded server
1198 by limiting the amount of memory that gets dirtied by mke2fs when it
1199 is using buffered I/O.
1201 E2fsck was needlessly closing and re-opening the file system as a side
1202 effect of adding Multiple Mount Protection (MMP). This isn't
1203 necessary for non-MMP file systems, so drop it.
1205 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
1206 can more easily diagnose memory allocation failures caused by
1207 insufficient memory. E2fsck will now abort if there are memory
1208 allocation failures when the file system is initially opened and
1209 during the block group descriptor checks. (Addresses Google Bug:
1212 If there are incorrect block group checks, e2fsck will now report the
1213 incorrect and corrected checksum values.
1215 The e2fsck progam can now write log files containing the details of
1216 the problems that were found and fixed directly, via configuration
1217 parameters in /etc/e2fsck.conf.
1219 Added the ability to limit the number of messages reported by e2fsck
1220 for a given problem type. This avoids a potential bottleneck if there
1221 is a serial console which can cause a boot sequence to take a long
1222 time if e2fsck needs to report many, many file system errors.
1224 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
1225 them to use much less memory for large file systems.
1227 The dumpe2fs program will now print the expected block group checksum
1228 if it is incorrect. This helps to diagnose problems caused by
1229 incorrect block group checksums.
1231 E2fsck now checks for extents with a zero length, since the kernel
1232 will oops if it comes accross such a corrupted data structure. (See
1233 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
1235 E2fsck has a number of bugs relating to discard that have been fixed.
1236 (1) Fixed a bug which could cause e2fsck to discard portions of the
1237 inode table which were actually in use. (2) E2fsck will now avoid
1238 using discard if the block device doesn't zero data on discard, since
1239 otherwise this could cause problems if the file system gets corrupted
1240 in the future. (3) E2fsck will now avoid using discard when it is run
1241 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
1242 discards in the last block group.
1244 E2fsck's CPU utilization in pass 5 has been optimized, which will
1245 speed up e2fsck slightly.
1247 E2image will now skip copying uninitialized bitmap and inode table
1250 Fixed mke2fs -S so it does not corrupt the first block group's
1253 E2fsck will now check the new sysfs interface to determine if we are
1254 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
1256 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
1258 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
1263 Fixed various portability issues for non-Linux systems, particularly
1264 MacOS X, as well as Linux systems running with the just-released glibc
1267 Fix file descriptor leak in ext2fs_close() if the file system with
1268 uninit_bg is opened read/only with a backup superblock. (Addresses
1269 SourceForge Bug: #3444351)
1271 Fixed an invalid return in a non-void function in the quota code.
1272 (Addresses SourceForge Bug: #3468423)
1274 Fixed the debian rules file so that the calls to dpkg-buildflags works
1275 when the shell is dash.
1277 The debian package build now uses V=1 so that there is more
1278 information about potential build failures in debian buildd logs.
1280 If the uninit flags get cleared by functions such as
1281 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
1282 superblock is marked dirty and the block group descriptor checksum is
1283 updated if necessary.
1285 The debian rules file will now try to load debian/rules.custom of it
1286 exists. This flie can skip various builds for speed reasons if there
1287 is no need for the e2fsck-static or udeb packages. Available
1288 customizations in the rules file includes SKIP_STATIC=yes,
1289 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
1291 In addition, if the file misc/mke2fs.conf.custom.in exists in the
1292 source tree, it will be used instead of the standard misc.conf file in
1293 the upstream sources. This makes it easier for Debian-derived systems
1294 to distribute a custom mke2fs.conf file without having to worry about
1295 merge issues if future versions of e2fsprogs makes changes in the
1296 upstream default version of mke2fs.conf.
1299 E2fsprogs 1.42.1 (February 17, 2012)
1300 ===================================
1302 The mke2fs and e2fsck now use significantly less memory when creating
1303 or checking very large file systems. This was enabled by adding
1304 extent-based bitmaps which are stored using a red-block tree, since
1305 block and inode allocations tend to be contiguous.
1307 The command mke2fs -S is used as a last ditch recovery command to
1308 write new superblock and block group descriptors, but _not_ to destroy
1309 the inode table in hopes of recovering from a badly corrupted file
1310 system. So if the uninit_bg feature is enabled, mke2fs -S will now
1311 set the unused inodes count field to zero. Otherwise, e2fsck -fy
1312 after using mke2fs -S would leave the file system completely empty.
1314 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
1315 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
1316 installed an mke2fs binary using that name.
1318 The usage and help messages for the -G, -t and -T options in mke2fs
1321 If e2fsck needs to use the backup group descriptors, the
1322 ext2fs_open2() function clears the UNINIT bits to ensure all of the
1323 inodes in the file systems get scanned. However, the code which reset
1324 the UNINIT flags did not also recalculate the checksum, which produced
1325 many spurious (and scary) e2fsck messages. This has been fixed by
1326 resetting cheksums when the UNINIT bits are cleared.
1328 Relax a check in e2fsck which required that the block bitmap to be
1329 initialized when the inode bitmap is in use. This will allow us to
1330 eventually eliminate code from the kernel which forcibly initialized
1331 the block bitmap when the inode bitmap is first used, requiring an
1332 extra journal credit and disk write. (Addresses Google Bug: #5944440)
1334 Make sure rdebugfs (which may be installed setuid or setgid disk) does
1335 not honor environment variables if euid != uid or egid != gid.
1337 Debugfs's ncheck command has been optimized and now is much more
1338 robust with faced with corrupted file systems. The ncheck command
1339 also now has a -c option which will verify the file type information
1340 in the directory entry to see if matches the inode's mode bits. This
1341 is extremely useful when trying to use debugsfs to determine which
1342 parts of the file system metadata can be trusted.
1344 E2image will try to use ftruncate64() to set the i_size for raw
1345 images, instead of writing a single null byte. This avoid allocating
1346 an extra block to the raw image, for those file systems and/or
1347 operating systems that support this. (Linux does.) In addition, fix
1348 a logic bug that caused the file to not be properly extended if the
1349 size of the last hole was exactly an multiple of a megabyte.
1351 Fixed a bug in resize2fs where for 1k and 2k file systems, where
1352 s_first_data_block is non-zero, this wasn't taken into account when
1353 calculate the minimum file system size for use with the -M option.
1355 Fixed the badblocks program to honor the -s flag when in read-only -t
1356 mode. (Addresses Debian Bug #646629)
1358 Update Czech, Dutch, French, Polish, and Sweedish translation from the
1359 Translation Project.
1361 Fixed various Debian Packaging issues so that dpkg-buildflags is used
1362 if present, which allows e2fsprogs to be built with security hardening
1363 flags. (Addresses Debian Bugs: #654457)
1368 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
1369 This was only an issue for programs compiled against e2fsprogs 1.41
1370 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
1373 The libext2fs library now uses sysconf() to fetch the page size, instead
1374 of the deprecated getpagesize().
1376 The ext2fs_get_pathname() function will return a partial path if an a
1377 directory in the path is not a directory, displaying it as an inode
1378 number in angle brackets instead of giving up and displaying an error.
1379 This is much more helpful when a user is trying to debug a corrupted
1382 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
1384 Added a new library function, ext2fs_file_get_inode_num(), for use by
1387 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
1388 file, it actually works.
1390 The block iterator now properly honors the BLOCK_ABORT flag for
1391 extent-based flags. Previously, it didn't, which generally made code
1392 be less efficient, but it could cause bugs in ext2fs_link(), for
1393 example, by causing it to insert multiple directory entries.
1395 Fixed an (harmless other than causing a compiler warning) use of an
1396 uninitialized variable in e2fsck's MMP code.
1399 E2fsprogs 1.42 (November 29, 2011)
1400 ==================================
1402 This release of e2fsprogs has support for file systems > 16TB. Online
1403 resize requires kernel support which will hopefully be in Linux
1404 version 3.2. Offline support is not yet available for > 16TB file
1405 systems, but will be coming.
1407 This release of e2fsprogs has support for clustered allocation. This
1408 reduces the number of block (now cluster) bitmaps by allocating and
1409 deallocating space in contiguous power-of-2 collections of blocks,
1410 which are called clustered. This is a file system level feature,
1411 called 'bigalloc', which must be enabled when the file system is
1412 initially formatted. It is not backwards compatible with older
1415 Added support for the Multi-Mount Protection (MMP) feature.
1417 E2fsck more efficiently uses scratch files for really big file
1418 systems. (This is a feature that has to be turned on explicitly; see
1419 [scratch_files] in the e2fsck.conf man page.)
1421 Fix a bug in e2fsck where if the free blocks and inodes counts are
1422 incorrect, e2fsck would fix them without printing an error message.
1423 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
1424 any explanation of what was fixed.
1426 E2fsck will no longer attempt to clone an extended attribute block in
1427 pass1b handling if the file system does not support extended
1430 E2fsck will be more careful accidentally asking the user to continue
1431 if the file system is mounted, so that an escape sequence won't cause
1432 a false positive. (Addresses Debian Bug: #619859)
1434 E2fsck now uses less cpu time in pass 5 when large portions of the
1435 bitmaps are uninitialized.
1437 E2fsck will no longer segault when a corrupted file system has a bad
1438 extent, and removing it leads to a block needing to be deallocated.
1439 (Addresses SourceForge Bug: #2971800)
1441 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
1442 and print debugging information to make it easier to find potential
1445 E2fsck will check to see if the bad block inode looks insane, and will
1446 skip trying to use if it certain fields which should be zero look
1447 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
1448 to get confused and do more harm than good.
1450 If e2fsck modifies certain superblock fields which the kernel doesn't
1451 look at, it will now mark the superblock as dirty without marking the
1452 file system as changed. This avoids signalling the init scripts that
1453 a reboot is necessary, since the kernel isn't going to look at those
1454 fields, so it won't care if they have been changed.
1456 Fixed a bug in the libext2fs library (in the binary search routine of
1457 the icount abstraction) that could (very, very rarely) cause e2fsck to
1458 die in the middle of pass 1 or pass 2 processing.
1460 E2fsck will not try to do a discard operation if the -n option was
1461 specified on the command line.
1463 E2fsck now supports an extended "discard" option which will cause
1464 e2fsck to attempt discard all unused blocks after a full, successful
1467 E2fsck will check for the bad block inode to make sure it looks sane
1468 before trusting it, to avoid causing more harm than good to the file
1471 E2fsck now returns additional status bits in its exit code if it
1472 aborts early in the e2fsck run.
1474 E2fsck now correctly calculates the maximum file size in the case of
1475 the huge_file file system feature enabled without extents.
1477 The mke2fs and e2fsck programs now tries to use the punch hole command
1478 as a "discard" when operating on normal files.
1480 The e2image program now supports the qcow2 format, which is a more
1481 efficient way of capturing file system dumps.
1483 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
1484 per-device defaults to be specified in the configuration file.
1486 Mke2fs now supports the reserved_ratio relation in the [defaults] and
1487 [fs_types] section in mke2fs.conf.
1489 Mke2fs now creates extent-mapped directories for the root and
1490 lost+found directories.
1492 Mke2fs will skip zero'ing the journal if the extended option
1493 "lazy_journal_init" is specified. This can save a lot of time, but it
1494 does add a small amount of risk if the system crashes before the
1495 journal is overwritten entirely once. It is epsecially useful for
1498 Mke2fs will now create file systems that enable user namespace
1499 extended attributes and with time- and mount count-based file
1500 system checks disabled.
1502 Mke2fs will not set a stride or strip size of one block based on block
1503 device attributes obtained from sysfs.
1505 Mke2fs now displays a progress report during the discard process.
1507 Mke2fs now handles extreme file system parameters correctly which
1508 previously caused the inodes per group to drop below 8, leading to a
1509 segfault. (The inodes per group must be a multiple of 8, but the code
1510 didn't correctly deal with an inodes per group count less than 8.)
1512 Mke2fs and tune2fs previously would give an error if the user tried
1513 setting the stride and stripe-width parameters to zero; but this is
1514 necessary to disable the stride and stripe-width settings. So allow
1515 setting these superblock fields to zero. (Addresses Google Bug:
1518 Mke2fs now gives a warning if the auto-detected block size exceeds the
1521 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
1522 is the default), mke2fs will now set the s_max_mnt_count superblock
1523 field to -1, instead of 0. Kernels older then 3.0 will print a
1524 spurious message on each mount then they see a s_max_mnt_count set to
1525 0, which will annoy users. (Addresses Debian Bug: #632637)
1527 The default mke2fs.conf now has entries for "big" and "huge", which
1528 are needed for very big file systems.
1530 The resize2fs program now has support for a new online resize ioctl
1531 that can support file systems > 16TB, once it arrives in v3.x kernels.
1533 Fixed bug which caused resize2fs to fail when shrinking an empty file
1534 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
1536 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
1538 Allow tune2fs to remove external journals if the device can not be
1541 Debugfs's icheck will now correctly find inodes which use the
1542 searched-for block as an extended attribute block.
1544 Debugfs now has a new "punch" command which remove blocks from the
1547 Debugfs now has a new "e2freefrag" command which analyzes the free
1548 space fragmentation of the file system, using the same code as the
1551 Debugfs now has a "filefrag" command which displays information about
1552 a file's fragmentation.
1554 Add support to build a metadata-only, read-only, stripped-down version
1555 of debugfs called rdebugfs.
1557 Fixed a potential stack overrun bug in debugfs.
1559 The badblocks program now correctly recovers from I/O errors when
1560 direct I/O is being used. The badblocks command now also supports a
1561 -B option which forces the use of buffered I/O, and the -v option will
1562 provide a more detailed breakdown of read, write, and failed
1565 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
1567 Added support for journals larger than 2GB.
1569 Support using both hard links and symlinks when installing e2fsprogs.
1571 Add overflow checking to tune2fs -i's fsck interval, which must fit in
1574 The debugfs command now has a new 'blocks' command which prints out
1575 data blocks of a particular inode in a format which is useful for
1578 Filefrag will report 0 extents correctly in verbose mode. (Addresses
1579 RedHat Bugzilla: #653234)
1581 Filefrag has been fixed so its -v report prints the correct expected
1582 block number (previously there had been an off-by-one error). In
1583 addition, it will now display the number of contiguous extents when -v
1584 is not specified. This makes it consistent with the number of extents
1585 printed when the -v option was specified. In addition, the number of
1586 contiguous extents is far more interesting/useful than the number of
1587 physical extents for very large files. (Addresses Debian Bug:
1590 Logsave's usage message has been fixed. (Addresses Debian Bug:
1593 Avoid an infinite loop in ext2fs_find_block_device() if there are
1594 symlink loops in /dev caused by a buggy udev.
1596 Added a useful "fallocate" program to the contrib directory.
1598 Fixed an ABI compatibility problem in libext2fs which broke the dump
1599 program. Also added back some macros which dump needed so it could
1600 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
1603 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
1604 Debian Bug: #641667)
1606 Added internationalization support for libcom_err error table strings.
1608 Fixed various spelling mistakes found in various output strings found
1609 by I18N translators.
1611 Update translations: French, Chinese, Germany, Indonesian, Swedish,
1612 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
1615 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
1616 #614662, #632169, #641838, #627535, #629355)
1618 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
1624 Initial support for quota as an integrated feature, where the quota
1625 files are hidden system files that are automatically maintained by
1626 e2fsck is present, although disabled by default. It must be enabled
1627 by using the configure option --enable-quota.
1629 Reserved the on-disk fields for the metadata checksum and snapshot
1630 features, which are currently in development.
1632 The ext2fs library now has the new functions ext2fs_punch(),
1633 ext2fs_get_memzero() and ext2fs_file_get_inode().
1635 The ext2fs library now has support for calculating the crc32c checksum
1636 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
1638 The I/O manager now supports the discard operation.
1640 Reserved file system code points for new 1st class quota feature.
1642 Shortened the compilation lines by moving the autoconf defines to
1643 a config.h header file.
1645 Fixed a potential free of an unitialized pointer in
1646 ext2fs_update_bb_inode().
1648 Fixed miscellaneous gcc -Wall and coverity warnings.
1650 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
1652 Fixed a build failure when OMIT_COM_ERR is defined.
1654 Improved error checking and fixed memory leaks caused by error return
1657 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
1658 the fsync() to be skipped.
1660 Added a test for extent-mapped journals by mke2fs and tune2fs.
1662 Added a test for creating a large (over 4GB) journal using mke2fs.
1664 Added a test to make sure the inode size remains constant.
1666 The regression test script now prints the list of which tests failed.
1668 The regression test system now uses /tmp for its scratch files, which
1669 is often a tmpfs mounted file system and hence much faster.
1671 The i_e2image test was fixed so it works with valgrind.
1673 Tests that rely on debugfs are now skipped if debugfs wasn't built.
1675 Fixed the dependencies for "make check" so all required dependencies
1676 are built before running the gression tests.
1678 A link to com_err.h is installed in $(includedir) during a "make install".
1680 The po/*.gmo files are automatically rebuilt if they are missing or
1681 out of date. This helps out Debian packaging.
1683 Allow ext2fs_get_memalign() to compile on systems that don't have
1686 Fixed a namespace leak in libext2fs (tdb_null).
1689 E2fsprogs 1.41.14 (December 22, 2010)
1690 =====================================
1692 Fix spurious complaint in mke2fs where it would complain if the file
1693 system type "default" is not defined in mke2fs.conf.
1695 The resize2fs program will no longer clear the resize_inode feature
1696 when the number reserved group descriptor blocks reaches zero. This
1697 allows for subsequent shrinks of the file system to work cleanly for
1698 flex_bg file systems.
1700 The resize2fs program now handles devices which are exactly 16T;
1701 previously it would give an error saying that the file system was too
1704 E2fsck (and the libext2fs library) will not use the extended rec_len
1705 encoding for file systems whose block size is less than 64k, for
1706 consistency with the kernel.
1711 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
1712 been fixed. (Addresses Sourceforge Bug: #3138115)
1714 The ext2fs_block_iterator2() function passed an incorrect ref_offset
1715 to its callback function in the case of sparse files. (Addresses
1716 Sourceforge Bug: #3081087)
1718 Fix some type-punning warnings generated by newer versions of gcc.
1721 E2fsprogs 1.41.13 (December 13, 2010)
1722 =====================================
1724 E2fsck now supports the extended option "-E journal_only", which
1725 causes it to only do a journal replay. This is useful for scripts
1726 that want to first replay the journal and then check to see if it
1729 E2fsck will now support UUID= and LABEL= specifiers for the -j option
1730 (which specifies where to find the external journal). (Addresses
1733 E2fsck now has support for the problems/<problem code>/force_no
1734 configuration option in e2fsck.conf, which forces a problem to not be
1737 Dumpe2fs will now avoid printing large negative offsets for the bitmap
1738 blocks and instead print a message which is a bit more helpful for
1739 flex_bg file systems.
1741 Mke2fs will now check the file system type (specified with the -t
1742 option) to make sure it is defined in the mke2fs.conf file; if it is
1743 not, it will print an error and abort. If the usage type (specified
1744 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
1745 warning but will continue. (Addresses Debian Bug #594609)
1747 Clarified error message from resize2fs clarifying that on-line
1748 shrinking is not supported at all. (Addresses Debian Bug #599786)
1750 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
1751 displayed. (Addresses Debian Bug #555456)
1753 E2fsck will open the external journal in exclusive mode, to prevent
1754 the journal from getting truncated while it is in use due to a user
1755 accidentally trying to run e2fsck on a snapshotted file system volume.
1756 (Addresses Debian Bug #587531)
1758 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
1761 The tune2fs program can now set the uninit_bg feature without
1764 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
1765 default mount options settings which were added in 2.6.35.
1767 The e2fsck and dumpe2fs programs now support the new ext4 superblock
1768 fields which track where and when the first and most recent file
1769 system errors occurred. These fields are displayed by dumpe2fs and
1770 cleared by e2fsck. These new superblock fields were added in 2.6.36.
1772 Debugfs now uses a more concicse format for listing extents in its
1773 stat command. This format also includes the interior extent tree
1774 blocks, which previously was missing from stat's output for
1777 Debugfs has a new option, -D, which will request Direct I/O access of
1780 Mke2fs will skip initializing the inode table if a device supports
1781 discard and the discard operation will result in zero'ed blocks.
1783 Badblocks will now correctly backspace over UTF-8 characters when
1784 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
1785 Debian Bugs #583782 and #587834)
1787 E2freefrag will now display the total number of free extents.
1789 Resize2fs -P no longer requires a freshly checked filesystem before
1790 printing the minimum resize size.
1792 Fixed a floating point precision error in a binary tree search routine
1793 that can lead to seg fault in e2fsck and resize2fs.
1795 Fixed a bug in e2fsck where if both the original and backup superblock
1796 are invalid in some way, e2fsck will fail going back to the original
1797 superblock because it didn't close the backup superblock first, and
1798 the exclusive open prevented the file system from being reopened.
1800 Fixed a big in e2freefrag which caused getopt parsing to fail on
1801 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
1803 Clarified an mke2fs error message so a missed common in an -E option
1804 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
1805 results in a more understandable explanation to the user.
1807 Mke2fs now displays the correct valid inode ratio range when
1808 complaining about an invalid inode ratio specified by the user.
1810 Mke2fs now understands the extended option "discard" and "nodiscard",
1811 and the older option -K is deprecated. The default of whether
1812 discards are enabled by default can be controled by the mke2fs.conf
1815 Mke2fs's handling of logical and physical sector sizes has been
1816 improved to reflect the fact that there will be some SSD's with 8k and
1817 16k physical sectors arriving soon. Mke2fs will no longer force block
1818 size to be the physical sector size, since there will be devices where
1819 the physical sector size is larger than the system's page size, and
1820 hence larger than the maximal supported block size. In addition, if
1821 the minimal and optimal io size are not exported by the device, and
1822 the physical sector size is larger than the block size, the physical
1823 sector size will be used to set the Raid I/O optimization hints in the
1826 E2fsck will now display a better, more specific error message when the
1827 user enters a typo'ed device name, instead of blathering on about
1828 alternate superblocks.
1830 Fixed various Debian Packaging Issues
1832 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
1833 #589345, #591083; Addresses Launchpad Bug: #505719)
1835 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
1836 Polish, Swedish, and Vietnamese translations.
1842 Fix a dependency definition for the static and profiled blkid
1843 libraries which could cause compile failures in some configurations.
1844 (Addresses Debian Bug: #604629)
1846 Add support for Direct I/O in the Unix I/O access layer.
1848 Fixed a memory leak in the Unix I/O layer when changing block sizes.
1850 Fixed minor memory leaks in mke2fs.
1852 Added a new function to the ext2fs library, ext2fs_get_memalign().
1854 The tst_super_size test program will check to make sure the superblock
1855 fields are correctly aligned and will print them out so they can be
1856 manually checked for correctness.
1858 Fixed some makefile dependencies for test programs in lib/ext2fs.
1860 Reserved the feature flags and superblock fields needed for the Next3

1864 EXT4_INCOMPAT_EA_INODE.
1867 E2fsprogs 1.41.12 (May 17, 2010)
1868 ================================
1870 Mke2fs now gives a correct error message if the external journal
1871 device is not found. (Addresses Red Hat Bug #572935)
1873 Resize2fs -P will now refuse to print a minimum size if the file
1874 system is not clean. Previously it would go ahead and print a minimum
1875 size anyway, which might not be correct, leading to user confusion.
1877 E2fsck now tests for extents that begin at physical block 0 and
1878 rejects them as invalid. (Addresses Google Bug: #2573806)
1880 Fixed a bug in e2fsck which could cause it to crash when trying to
1881 remove an invalid extent and the block bitmaps hadn't yet been loaded.
1882 (Addresses SourceForge Bug: #2971800)
1884 E2fsck now will completely skip time-based checks if the system clock
1885 looks insane or the option broken_system_clock is set in
1888 E2fsck would previously report an i_blocks corruption for a 4T file
1889 created using posix_fallocate; this bug has been fixed.
1891 E2fsck will now correctly mark a sparse journal as invalid and will
1892 delete and recreate the journal to address the problem.
1894 E2fsck would previously incorrectly ask the user whether she would
1895 like to abort the file system check after finding a problem --- and
1896 then abort regardless of the user's answer. This is annoying, and
1899 E2fsck can now continue even if it fails to recreate the resize
1900 inode; previously it would just abort the file system check
1903 E2fsck could potentially remove directory entries for inodes found in
1904 the unused region of the inode table; this would generally happen on
1905 ext4 file systems that do not use journaling. This bug has been fixed
1906 by not clearing these directory entries once it has been established
1907 that bg_unused_inodes may not be trustworthy; once pass #2 has been
1908 completed, e2fsck will restart the file system check from the
1909 beginning, and then it will be safe to delete any directory entries
1910 pointing to inodes that appear to be deleted. (Addresses Google Bug:
1913 E2fsck will not try to set the block group checksums if the user
1914 cancels the fsck with a control-C. It's a bad idea to set the
1915 checksums if e2fsck hasn't been completed, and it often results an the
1916 error message, "Inode bitmap not loaded while setting block group
1917 checksum info". (Addresses Launchpad Bug: #582035)
1919 The mke2fs program now queries the kernel for the physical as well as
1920 the logical sector size, and will not allow a blocksize below the
1921 logical, and will strongly encourage a blocksize at least as big as
1922 the physical blocksize. This is needed for 4k sector drives that
1923 emulate 512 byte sector sizes.
1925 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
1926 rarely needed, but it is a legal value.
1928 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1929 not needed, and offer to clear it; this is a sign of a kernel bug, but
1930 more importantly, some released kernels may crash when this situation
1931 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
1933 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1934 i_size is correct. (Kernels starting with 2.6.34 will set
1937 The com_err library will now only output ^M (a CR character) when the
1940 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
1941 and Vietnamese translations.
1943 Fixed various Debian packaging issues --- see debian/changelog for
1944 details. (Addresses Debian Bugs: #571247, #563487)
1950 The regression test suite now uses its own mke2fs.conf file, so that
1951 downstream distributions want change the mke2fs.conf file which is
1952 distributed in the RPM or dpkg file, without worrying about screwing
1953 up the regression test results.
1955 Always build namei.o so that building with configure --disable-debugfs
1956 works correctly. Long-term, if we care about reduced e2fsprogs
1957 builds, we need a more general solution for deciding what .o files are
1958 needed for a particular build. Given that install floppies are going
1959 (gone?) the way the dodo bird, we probably don't care, though.
1960 (Addresses Sourceforge Bug: #2911433)
1962 Add configure options --enable-symlink-build and
1963 --enable-symlink-install, which allow e2fsprogs be built using
1964 symlinks instad of hard links, and to be installed using symlinks
1965 instead of hard links, respectively. It is useful when the file
1966 system where the build is taking place, or the file system where
1967 e2fsprogs is installed, can't handle hard links for some reason.

1973 E2fsprogs 1.41.11 (March 14, 2010)
1974 ==================================
1976 E2fsck will no longer give a fatal error and abort if the physical
1977 device has been resized beyond 2**32 blocks. (Addresses Launchpad
1980 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
1981 the allocation status of the block <blk>. (Addresses Debian Bug:
1984 E2fsck now prints a much more emphatic and hopefully scary message
1985 when a file system is detected as mounted while doing a read/write
1986 check of the filesystem. Hopefully this will dissuade users from
1987 thinking, "surely that message doesn't apply to *me*" :-(
1989 E2fsck -n will now always open the file system read-only. We now
1990 disallow certain combination of options which previously were manual
1991 exceptions; this is bad because it causes users to think they are
1992 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
1993 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
1995 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
1996 it detected a badly aligned partition. Unfortunately, this broke some
1997 distribution installation scripts, so it now just prints the warning
1998 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
1999 Launchpad Bug: #530071)
2001 Mke2fs would take a long time to create very large journal files for
2002 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
2005 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
2006 2.6.34 kernels to make e2fsck not complain about blocks deliberately

2009 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
2010 e2fsck -fD can corrupt non-indexed directories when are exists one or
2011 more file names which alphabetically sort before ".". This can happen
2012 with ext2 filesystems or for small directories (take less than a lock)
2013 which contain filenames that begin with a space or some other
2014 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
2021 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

2030 ====================================
2032 Fix resize2fs bug which causes it to access invalid memory.
2034 Add libss support for libreadline.so.6.
2036 Fix e2fsck's check for extent-mapped directory with an incorrect file
2039 Add new e2fsck.conf configuration option, default/broken_system_clock
2040 to support systems with broken CMOS hardware clocks. Also, since too
2041 many distributions seem to have broken virtualization scripts now,
2042 e2fsck will by default accept dates which are off by up to 24 hours by
2043 default. (Addresses Debian Bugs: #559776, #557636)
2045 Fix a bug where mke2fs may not use the best placement of the inode
2046 table when there is only room for a single block group in the last
2049 E2fsck is now smarter when it needs to allocate blocks in the course
2050 of fixing file system problems. This reduces the number of spurious
2051 differences found in pass #5.
2053 E2fsck will no longer rehash directories which fit in a single
2056 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
2057 sparse directories which use extents).
2059 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
2061 Fix a bug in filefrag where on platforms which can allow file systems
2062 with 8k blocks, that it doesn't core dump when it sees a file system
2063 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
2066 E2fsck will correctly fix directories that are have an inaccurate
2067 i_size as well as other problems in a single pass, instead of
2068 requiring two e2fsck runs before the file system is fully fixed.
2070 Fix e2fsck so it will correctly find and detect duplicate directory
2071 entries for non-indexed directories. ( Addresses Sourceforge Bug:

2100 have the HUGE_FILE_FL flag set.
2102 Fix e2fsck's handling of 64-bit i_blocks fields.
2104 E2fsck will now print "Illegal indirect block", "Illegal
2105 double-indirect block", etc., instead of "Illegal block #-1" or
2106 "Illegal block #-2", etc. This makes it easier for users to
2107 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
2109 Mke2fs now will obtain get device topology information from blkid and
2110 use it to populate the superblock stride and stripe sizes. It will

2164 E2fsprogs 1.41.9 (August 22, 2009)
2165 ==================================
2167 Fix a bug in e2fsck routines for reallocating an inode table which
2168 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
2169 filesystem feature with a relatively rare (and specific) filesystem
2170 corruption. This fix causes e2fsck to try to find space for a new
2171 portion of the inode table in the containing flex_bg, and if that
2172 fails, the new portion of the inode table will be allocated in any
2173 free space available in the filesystem.
2175 Make e2fsck less annoying by only asking for permission to relocate a
2176 block group's inode table once, instead of for every overlapping
2177 block. Similarly, only ask once to recompute the block group
2178 checksums, instead of once for each corrupted block group's checksum.
2180 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
2181 not present, and it needs to fall back to using the FIBMAP ioctl.
2183 Fix filefrag to correctly print the number of extents for zero-length
2184 files. (Addresses Debian Bug: #540376)
2186 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
2187 to more easily debug the FIBMAP code.
2189 Fixed filefrag for non-extent based files.
2191 Add a new program, e2freefrag, which displays information about the
2192 free space fragmentation in an ext2/3/4 filesystem.
2194 Fix inode resizing via tune2fs -I so that it works correctly in the
2195 face of non-empty bad blocks inodes, and if the filesystem was
2196 formatted using the "mke2fs -E stride=N" option for RAID arrays.
2198 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
2199 and corrupt large directories if the directory needs to shrink by more
2200 than one block. (Addresses Debian Bug: #537510)
2202 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
2203 last mount times are in the future, they are corrected even if
2204 buggy_init_scripts is set. This is needed because otherwise resize2fs
2205 will refuse to resize the filesystem, even after running "e2fsck -f".
2206 (Addresses Launchpad bug: #373409)
2208 E2fsck will now print much fuller information when the last mount time
2209 or last written time is in the future, since most people can't seem to

2211 failed CMOS/RTS clock battery.

2236 there aren't any free blocks or inodes in the already-used block

2258 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
2259 will be careful not to close the file descriptor for its unix domain
2260 socket when it detaches itself from the controlling tty. Also add
2261 safety checks so that if the unix domain socket between the uuid
2262 library and uuidd program is closed for any reason, both the library
2263 and the uuidd will return an appropriate error code instead of looping
2264 in an infinite loop.
2266 The e2croncheck script, which creates an LVM snapshot and then checks

2301 E2fsprogs 1.41.7 (June 29, 2009)

2304 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
2305 uninitalized data into the portion of the inode beyond the first 128
2306 bytes when operating on inodes mapped via extents; potentially
2307 corrupting filesystems.
2309 Fix memory leaks in e2fsprogs, including a very large memory leak
2310 which can cause e2fsck to run out of memory when checking very large
2311 filesystems using extents.

2360 E2fsprogs 1.41.6 (May 30, 2009)
2361 ===============================
2363 Fix a critical regression in e2fsck introduced version 1.41.5 which
2364 can undo updates to the block group descriptors after a journal replay.
2366 If e2fsck receives an I/O error while replaying the journal, prompt
2367 the user whether they want to ignore the error or not; if e2fsck is
2368 run in preen mode, force fsck to abort the preen pass.
2370 Fix a bug which would cause e2fsck to core dump if the filesystem
2371 contains a corrupt extent header, and the user declines to clear the
2372 inode. (Addresses Sourceforge Bug: #2791794)
2374 Fix e2fsck to restart only once in the case of multiple block groups
2375 which inodes in use that are in the uninitialized part of the block
2376 group's inode table.
2378 To reduce user confusion, if the /etc/mtab file is missing
2379 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
2380 new, explicit error code to indicate this case. This will cause
2381 e2fsck to give a clearer error message when the user is using buggy
2382 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
2385 Fix e2fsck so that if the primary group descriptors are corrupted, but
2386 the backup superblock is entirely invalid, to go back to using (and
2387 fixing) the priary group descriptors instead of completely giving up
2388 on the filesystem. (Addresses Debian Bug: #516820)
2390 Change e2fsck to not abort a preen pass if an inode is found to have
2391 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
2392 kernels (post 2.6.29) will ignore this field. So let's fix it
2393 automatically during the preen pass instead of forcing the user to fix
2394 this up manually. (Addresses Debian Bug: #526524)
2396 Add resource tracking for e2fsck passes 1b through 1d.
2398 Speed up e2fsck by eliminating unnecessary journal checks if the
2399 filesystem is already mounted and doesn't need recovery (since the
2400 kernel would have run the journal when the filesystem was mounted.)
2401 Also speed up e2fsck by avoiding unnecessary block group descriptor
2402 updates in ext2fs_close().
2404 Add support to chattr to migrate inodes from using direct/indirect
2407 Avoid corrupting the filesystem if there is an attempt to shrink a
2408 filesystem using resize2fs smaller than posible by making
2409 ext2fs_set_bmap() more careful not to delete the old block until the
2410 new block can be inserted. In addition, fix a bug in how the minimum
2411 size of the filesystem (plus a safety margin) is calculated, and
2412 modify resize2fs to refuse to shrink the filesystem below that minimum
2413 size without the force flag.
2415 Teach blkid to try to figure out DM device names using take advantage
2416 of information in sysfs when running on kernels (2.6.29 and later)
2417 which provide this information in /sys/block/dm-<N>/dm/name; this is
2418 much faster than scanning for the devncie number in /dev/mapper.
2420 Fix blkid to prefer /dev/mapper/<name> device names instad of the
2421 private /dev/dm-X names.
2423 Add an -a option to debugfs's close_filesys command which writes any
2424 changes to the superblock or block group descriptors to all of the
2425 backup superblock locations.
2427 Add support to the filefrag program to use the FIEMAP ioctl.
2429 Update Chinese translation from the Translation Project.
2431 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
2432 Launchpad Bug: #381854)
2434 Fixed various Debian packaging issues --- see debian/changelog for
2435 details. (Addresses Debian Bug #506064)
2441 Add test code to make sure e2fsck's problem.c doesn't have two problem
2442 codes assigned to duplicate values.
2444 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
2445 (Addresses Sourceforge Bug: #2780205)
2447 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
2448 function declaration for init_resource_track() and
2449 print_resource_track() when RESOURCE_TRACK is not defined.
2451 The test code which is used to build the tst_csum progam has been
2452 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
2453 avoid compile problems caused by not having a prototype for
2454 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
2456 Update the config.guess and config.sub file to the latest from the
2457 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
2458 Debian Bug: #528330)
2460 Add a new function, ext2fs_extent_open2(), which behaves like
2461 pext2fs_extent_open(), but uses the user-supplied inode structure
2462 when opening an extent instead of reading the inode from disk.
2465 E2fsprogs 1.41.5 (April 23, 2009)
2466 =================================
2468 Fix a number of filesystem corruption bugs in resize2fs when growing
2469 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
2472 Debugfs can now set i_file_acl_high via the set_inodes_field command,
2473 and print a 64-bit file acl. This is useful for debugging filesystem
2474 corruptions where the high bits of i_file_acl_high are set. E2fsck
2475 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
2476 since some Linux kernel versions pay attention to this field even when
2479 Speed up e2fsck when checking clean filesystems by avoiding
2480 unnecessary block reads, and coalescing the block group descriptor
2481 blocks so they are read using a single read operation.
2483 The libuuid library will now close all file descriptors before running
2484 uuidd. This avoids problems when the calling program has open sockets
2485 which then never get closed because uuidd is a long-running helper
2486 daeomn. (Addresses Launchpad bug: #305057)
2488 In order to avoid unnecessary full filesystem checks by e2fsck after
2489 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
2490 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
2492 Mke2fs will avoid trying to create the journal when run in
2493 superblock-only mode (mke2fs -S), since the left-over journal in the
2494 inode table will cause mke2fs to fail.
2496 Fix a bug in libext2fs functions that check to see if a particular
2497 device or filesystem image is mounted, which would cause these
2498 functions to report that a file identical to the (relative) pathname
2499 used by a pseudo-filesystem was mounted when in fact it was not.
2501 Update Czech translation from the Translation Project.
2503 Add Chinese (simplified) translation from the Translation Project.
2505 Fix support for external journals (which was broken in e2fsprogs
2508 Fix a regression in debugfs where the "stat" command when no
2509 filesystem was open would cause debugfs to crash with a segmentation
2512 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
2513 used to support filesystems without a journal. Update the blkid
2514 library so it understands this.
2516 The blkid library will remove an entry from the blkid cache
2517 representing the entire disk if partitions are found, since presuambly
2518 the device previously had no partition table, but has now transitioned
2519 to using a partition table.
2521 Add a check to mke2fs and tune2fs that the argument to the -m option
2522 (which specifies the reserved ratio) must be greater than zero.
2523 (Addresses Debian Bug: #517015)
2525 Add support for tracking the number kilobytes written to the
2526 filesystem via the superblock field s_kbytes_written. It will be
2527 updated by the kernel as well as by e2fsprogs programs which write to
2528 the filesystem. This is useful for tracking the wear to filesystems
2529 on Solid Sstate Drives.
2531 Fix compatibility issue in the libext2fs info file and makeinfo
2532 version 4.12. (Addresses Red Hat Bugzilla: #481620)
2534 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
2536 Fixed various Debian packaging issues --- see debian/changelog for
2537 details. (Addresses Debian Bug: #506279)
2542 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
2545 Fix various gcc compilation warnings and other programming cleanups.
2546 (Addresses Red Hat Bugzilla: #486997)
2548 Add support for building the blkid command statically.
2550 Add support for disabling the built-in blkid library in favor of a
2551 system-installed blkid implementation via the configure option
2555 E2fsprogs 1.41.4 (January 27, 2009)
2556 ===================================
2558 Fixed a bug which could sometimes cause blkid to return an exit value
2559 of zero for a non-existent device (Addresses Debian Bug: #502541)
2561 Blkid will now recognize ext3 filesystems that have the test_fs flag
2562 set as ext3 filesystems.
2564 The blkid library will now recognize btrfs filesystems and swap
2565 devices currently used by user-level software suspend.
2567 Tune2fs now updates the block group checksums when changing the UUID
2568 to avoid causing e2fsck to complain vociferously at the next reboot.
2570 Tune2fs's inode size resizing algorithms have been fixed so it is not
2571 vastly inefficient for moderate-to-large filesystems, due to some
2572 O(n**2) and O(n*m) algorithms that didn't scale well at all.
2574 Fix tune2fs's inode resizing algorithm so it will not corrupt
2575 filesystems laid out for RAID filesystems; in addition, tune2fs will
2576 refuse to change the inode size for filesystems that have the flex_bg
2577 feature enabled. (This is a limitation in the current implementation
2580 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
2581 filesystems with 32-bit block numbers, when the headers for 64-bit
2582 block numbers was added. This regression has been fixed.
2584 Debugfs's ncheck command has been fixed to avoid printing garbage
2585 characters at the end of file names.
2587 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
2588 when shrinking filesystems with uninit_bg feature would not be moved.
2589 In addition, blocks and inode table blocks were not being correctly
2590 freed when shrinking filesystems with the flex_bg feable, which caused
2591 resize2fs -M to fail. Finally, when blocks are moved, make sure the
2592 uninitialized flag in extents is preserved.
2594 Fix bug which caused dumpe2fs to abort with an error if run on a
2595 filesystem that contained an external journal.
2597 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
2598 for this in argv[0] to provide better legacy support for these
2599 distributions. This is a practice that should NOT be continued,
2602 Mke2fs now has a new option -U, which allows the user to specify the
2603 UUID that should be used for the new filesystem.
2605 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
2606 minus one block. This allows users who have read that ext3 supports
2607 up to 16TB filesystems and who create a 16TB LVM to not get confused,
2608 since the true limit is really 16TB minus one block.
2610 E2fsck will no longer abort an fsck run if block group has an errant
2613 E2fsck now distinguishes between fragmented directories and fragmented
2614 files in verbose mode statistics and in the fragcheck report.
2616 Fix a bug in e2fsck which casued it double count non-contiguous
2617 extent-based inodes.
2619 E2fsck will leave some slack space when repacking directories to allow
2620 room for a few directory entries to be added without causing leaf
2621 nodes to be split right away.
2623 Fix a bug which caused e2fsck to crash when it comes across a
2624 corrupted interior node in an extent tree with the error message:
2625 "Error1: Corrupt extent header on inode XXXXXX"
2627 E2fsck problem descriptions involving the journal are no longer
2628 referred to as "ext3" problems, since ext4 filesystems also have
2631 Fix a long-standing bug in e2fsck which would cause it to crash when
2632 replying journals for filesystems with block sizes greater than 8k.
2634 Update Catalan translation from the Translation Project.
2636 Fixed various Debian packaging issues --- see debian/changelog for
2637 details. (Addresses Debian Bugs: #503057, #502323, #511207)
2642 Fix build of e2fsck.profiled, and add support for building profiled
2643 binaries in the misc directory if configured with --enable-profile.
2645 The ext2fs_open() function now performs more sanity checks on the
2646 superblock to avoid potential divide by zero errors by other parts of
2649 The ext2fs_read_inode_full() function now has a safety check to avoid
2650 a segmentation fault on corrupted filesystems.
2652 The ext2fs_new_inode() function now has a sanity check so that if the
2653 s_first_inode field in the superblock is insane, it will return
2654 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
2656 To avoid segmentation faults, ext2fs_block_alloc_stats() and
2657 ext2fs_inode_alloc_stats() now validates the passed inode or block
2658 number to avoid overrunning an array boundary.
2660 Various signed/unsigned errors for variables containing block numbers
2663 Accomodations for gcc's stupidity in not realizing that constant
2664 strings that do not contain a '%' character are safe to use in format
2665 strings have been made so that distributions that want to compile
2666 e2fsprogs with -Werror=format-security have an easier time doing so.
2668 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
2670 Added the utility make-sparse.c to the contrib directory.
2672 The ext2fs_block_iterate2() function now reflects errors from
2673 ext2fs_extent_set_bmap() to the caller, if the callback tries to
2674 change a block on an extent-based file, and ext2fs_extent_set_bmap()
2675 fails for some reason (for example, there isn't enough disk space to
2676 split a node and expand the extent tree.
2678 The ext2fs_block_iterate2() function will preserve the uninit flag in
2679 extents when the callback function modifies a block in an extent-based
2682 E2fsck will now flag filesystems that have an insane s_first_ino field
2683 in their superblock, and attempt to use a backup superblock to repair
2687 E2fsprogs 1.41.3 (October 12, 2008)
2688 ===================================
2690 E2fsck has been fixed so it prints the correct inode number for
2691 uinit_bg related problems.
2693 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
2694 is available on linux. This can be disabled via a configuration
2695 option in /etc/e2fsck.conf.
2697 Fix a file descriptor leak in libblkid when checking to see if an ext4
2698 or ext4dev module exists.
2700 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
2701 while trying to close a filesystem can lead to infinite loops.
2702 (Addresses Red Hat Bugzilla #465679)
2704 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
2705 will cause resize2fs to drop into an infinite loop. (Addresses Red
2706 Hat Bugzilla: #465984)
2708 Add a check in the Unix I/O functions in libext2fs so that when a
2709 device is opened read/write, return an error if the device is
2710 read-only using the BLKROGET ioctl.
2712 Fix debugfs's ncheck command so that it prints all of the names of
2713 hardlinks in the same directory.
2715 Fix a bug in libblkid so it correctly detects whether the ext4 and
2716 ext4dev filesystems are available, so that the ext4dev->ext4
2717 fallback code works correctly.
2722 Fix a parallel build problem by making sure util/subst is built before
2723 trying to build the lib/et directory. (Addresses Sourceforge Bug:
2726 Updated "make depend" information for crc16.o
2729 E2fsprogs 1.41.2 (October 2, 2008)
2730 ==================================
2732 Fix e2fsck's automatic blocksize detection. This fixes a regression
2733 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
2734 specifies a block number using the -b option if the blocksize option
2735 isn't also specified using -B. Unfortunately, users very commonly
2736 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
2737 superblock; in fack e2fsck will often suggest this kind of command
2740 Enhance the debugfs's "ncheck" command so it will print all of the
2741 pathnames for the specified inodes. (Previously, in some cases ncheck
2742 might not print a pathname for an inode at all if some of the other
2743 inodes had multiple hard links.)
2745 Enhance debugfs's "hash" command so the hash seed can be specified via
2746 a command-line option. In addition, allow the hash algorithm to be
2747 specified by name instead of just by number.
2749 Fix e2fsck so that we don't accidentally print the translation file's
2750 header when asking the user a custom question so there is no prompt
2751 defined for a particular problem record. For example, the question
2752 "Run journal anyway" will get the PO header tacked on because e2fsck
2753 erroneously passed the null string to _(). (Addresses Launchpad Bug:
2756 Enhance badblocks so that it can test a normal file which is greater
2759 Enhance the badblocks command so that it displays the time and
2760 percentage complete when in verbose mode. (Addresses Debian Bug:
2763 Fix a potential memory leak in a error handling path in debugfs's
2766 Fix a potential memory corruption problem if a memory allocation fails
2769 Fix the usage message for debugfs's logdump command to be consistent
2770 with its man manpage.
2772 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
2773 and Sweedish translation from the Translation Project.
2775 Add documentation for the file I/O functions to the libext2fs.texinfo
2776 file. (Addresses Debian Bug: #484877)

2779 #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
2781 Fixed various Debian packaging issues --- see debian/changelog for
2782 details. (Addresses Debian Bug: #497619)
2787 Fix a potential file descriptor leack in libcom_err by setting the
2788 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
2791 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
2792 has been carrying a patch for a long time to prevent a largely
2793 theoretical race condition if a multi-threaded application adds and
2794 removes error tables in multiple threads. Unfortunately SuSE's
2795 approach breaks compatibility by forcing applications to link and
2796 compile with the -pthread option; using pthread mutexes has
2797 historically been problematic. We fix this by using sem_post/sem_init
2800 Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
2801 Sourceforge Bug: #2087502)
2803 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
2804 libraries when using ELF shared libraries.
2806 Fix ELF shared library when building on systems that don't already
2807 have the e2fsprogs shared libraries already installed. (Addresses
2808 Sourceforge Bug: #2088537)
2810 Fix the pkg-config files so they work correctly when linking with
2811 static libraries and fix the include directory so programs don't have
2812 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
2813 instead. (Addresses Sourceforge Bug: #2089537)
2815 Make sure ext2fs_swab64() is compiled for all platforms, and not just
2816 for x86. (Addresses Debian Bug: #497515)
2818 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
2819 non-x86 platforms. (They had been removed for x86 earlier.)
2821 Fix diet libc compilation support, which had bitrotted due to lack of
2822 TLC. Fixing this improves general portability.
2824 When installing the link library when using ELF shared libraries,
2825 avoid using absolute pathnames if the link library and the shared
2826 library are installed in the same directory. (Addresses Sourceforge
2829 Fix gen-tarball so it will work even if the top-level directory has
2830 been renamed to something other than "e2fsprogs". Also make
2831 gen-tarball print the size of the resulting tar.gz file.
2834 E2fsprogs 1.41.1 (September 1, 2008)
2835 ====================================
2837 Many people are forgetting to update their mke2fs.conf file, and this
2838 causes ext3, ext4, and ext4dev filesystems won't get created with the
2839 proper features enabled. We address this in two ways. First, mke2fs
2840 will issue a warning if there is not definition for an ext3, ext4, or
2841 ext4dev filesystem and the user is trying to create such a filesystem
2842 type. Secondly, when installing from a source build, "make install"
2843 will provide basic configuration file handling for /etc/mke2fs.conf.
2844 If it exists, and does not mention ext4dev, it will be moved aside to
2845 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
2846 be installed. If the existing /etc/mke2fs.conf file does mention
2847 ext4dev, then "make install" will install official mke2fs.conf file as
2848 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
2849 they should look to see if any changes need to be merged.
2851 The mke2fs program will now create the journal in the middle of the
2852 filesystem, since this minimizes seek times on average for fsync-heavy
2853 workloads. In addition, mke2fs will now create journals using extents
2854 for filesystems that support them. This results in a more efficient
2855 encoding for the journal since it eliminates the need for using
2858 The mke2fs program will avoid allocating an extra block to the
2859 journal. (Addresses Sourceforge Bug: #1483791)
2861 Mke2fs will correctly enforce the prohibition against features
2862 (specifically read-only features) in revision 0 filesystems. (Thanks
2863 to Benno Schulenberg for noticing this problem.)
2865 Mke2fs previously would occasionaly create some slightly non-optimally
2866 placed inode tables; this bug has been fixed.
2868 The mke2fs and tune2fs programs now print the correct usage message
2869 describing the maximum journal size. (Addresses Debian Bug: #491620)
2871 Add support for setting the default hash algorithm used in b-tree
2872 directories in tune2fs (from a command-line option) or mke2fs (via
2873 mke2fs.conf). In addition, change the default hash algorithm to
2874 half_md4, since it is faster and better.
2876 The blkid library will now recognize MacOS hfsx filesystems, and
2877 correctly extract the label and uuid for hfs, hfsx, and hfsplus
2878 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
2880 The blkid library has improved detection of JFS and HPFS filesystems.
2881 (Addresses Launchpad Bug: #255255)
2883 The blkid library is now much more efficiently handling devicemapper
2884 devices, mainly by no longer using the devicemapper library. This can
2885 speed up access for systems with a large number of device mapper
2888 Blkid had a number of cache validation bugs in libblkid that have been
2889 fixed. (Addresses Debian Bug: #493216)
2891 Resize2fs will now properly close out the "updating inode references"
2892 progress bar so there is a newline printed before printing the final
2893 "resize is successful" message.
2895 Resize2fs will now correctly handle filesystems with extents and/o
2896 uninitialized block groups correctly when file/directory blocks need
2897 to relocated (i.e., when shrinking a filesystem or if the resize_inode
2898 is not present). To support this, the ext2fs library now supports
2899 initializing inode and block bitmaps that are not yet initialized when
2900 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
2901 addition, e2fs_block_iterate2() can now support changing the location
2902 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
2903 been optimized to avoid creating unnecessary new extents when updating
2904 the location of blocks in the extent tree. This will also help out
2905 e2fsck's recovery of obscurely corrupted filesystems with extents,
2906 when blocks are claimed by multiple inodes.
2908 Add support for on-line resizing ext4 filesystem with the flex_bg
2909 filesystem feature. The method for doing so is not optimal, but to do
2910 a better job will require kernel support.
2912 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
2913 debugfs programs to not be able to read e2image files; the signed
2914 vs. unsigned bug in the code which read bitmaps from the e2image has
2915 been fixed. (Addresses Debian Bug: #495830)
2917 Resize2fs is now correctly managing the directory in-use counts when
2918 shrinking filesystems and directory inodes needed to be moved from one
2919 block group to another. This bug has been around since e2fsprogs
2920 1.26, and is largely harmless, but does cause a filesystem corruption
2921 which will be flagged by e2fsck after the filesystem has been shrunk.
2923 E2fsck will no longer issue spurious complaints about the inode size
2924 caused by very large extent-based files, and by blocks reallocated
2925 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
2926 Kernel Bugzilla: #11341)
2928 Mke2fs will now set the creation timestamp on the lost+found directory
2929 and the root directory. (More generally, all new inodes created using
2930 the ext2fs library will correctly set the creation timestamp.)
2932 E2fsck now correctly calculates ind/dind/tind statistics in the
2933 presence of extent-based files. In addition, "e2fsck -v" will report
2934 statistics of the depth of extent trees in the filesystem. E2fsck can
2935 also give an inode fragmentation report using "e2fsck -E fragcheck"
2936 which can be useful when debugging the kernel block allocation
2939 Fix support for empty directory blocks in ext4 filesystems with 64k
2940 blocksize filesystems.
2942 E2fsck will now print the depth of corrupt htree directories.
2944 Debugfs's htree command now correctly understands extent-based
2945 directories. It will also print out the minor hash as well as the
2948 Debugfs has a new command which will print the supported features of
2949 e2fsprogs, to enable scripts to know whether the installed version of
2950 e2fsprogs can support a specific feature.
2952 Debugfs will now write files using extents for filesystems that
2955 The error message printed by "tune2fs -I" if the inode size was too
2956 small was rather confusing, so it has been improved. Also, we won't
2957 try to create an undo log until we know that command-line-specified
2958 parameters such as "tune2fs -I <inode size>" are valid.
2960 Given some filesystems found "in the wild" that had non-zero block
2961 group checksums even though the uninit_bg/gdt_sum feature was not
2962 enabled, e2fsck would issue spurious error messages. Teach

2968 the block devices in the system and what they contain when given the
2969 -L option. (Addresses Debian Bug: #490527)
2971 The filefrag program now has a more accurate calculation for the
2972 number of ideal extents. (Addresses Debian Bug: #458306)
2974 The test I/O manager is now enabled by default, but its overhead is
2975 only incurred when it would be enabled via the TEST_IO_FLAGS or
2976 TEST_IO_BLOCK environment variables.
2978 Typographical errors in various program strings and usage messages
2979 have been fixed; most of these were pointed out by the e2fsprogs
2980 message catalog translators. (Thanks, translators!)
2982 Update and clarified various man pages, as well as some typographical
2983 errors in the libext2fs texinfo file.

2998 The "make check" target in the e2fsck directory now sets
2999 LD_LIBRARY_PATH before running the various e2fsck internal library
3002 The crc32 regression test in the e2fsck library is now portable to
3003 greater varienty of environments, including big-endian systems and
3004 when cross-building e2fsprogs for embedded systems. (Addresses
3005 Sourceforge Bug: #2019287)
3007 The ext2fs_extent_set_bmap() had some bugs when setting the first
3008 block in a file, or when replacing a single block extent. Those cases
3009 fortunately were came up relatively rarely when e2fsck was checking
3010 files, but caused some problems when resize2fs was shrinking

3016 Various ext2fs library functions --- ext2fs_block_iterate2(),

3018 allocated memory to avoid memory leaks in all of their error return
3021 Ext2ed was failing to build because masix support had been removed in
3022 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
3024 The configure script now respects the LDFLAGS environment variable if
3025 it is set when configure is called. (Addresses Sourceforge Feature
3028 Libuuid is now more portable to the Windows platform. (Addresses
3029 Sourceforge Feature Request: #1937287)
3031 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
3032 bare echo commands so that configure flags such as --quiet work
3033 correctly. (Addresses Sourceforge Patches: #2058794)
3035 A few uses of sprintf have been removed from the ext2fs library to
3036 make life easier for bootloaders with a limited libc environment.

3047 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
3048 top-level Makefile. That automatic rule is used to better support
3049 SCCS, but it caused problems for a particular niche distribution which
3050 likes to use configure.sh files to store the configure options used to
3051 build a package. Unfortuntaely GNU make will use the configure.sh to
3052 replace the configure script, resulting in a self-inflicted fork bomb
3053 leading to an out-of-memory crash.
3055 To support old GNU C compilers don't use C99/C++ comments, but only
3056 K&R style comments, and don't try to use __builtin_expect if __GNUC__
3057 is less than 3. (__builtin_expect is only supported for gcc versions
3058 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
3059 this is an optimization, we only try to use __builtin_expect for gcc 3
3062 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
3063 __LITTLE_ENDIAN, which are only defined by glibc's header files and
3064 hence isn't portable.
3066 For the convenience for some distributions that need a static tune2fs,
3067 the Makefile for misc/ now has a tune2fs.static target.
3069 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
3070 for extent-based files
3072 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
3075 All source files no longer have any trailing white space.
3077 The io_channel_read_blk64() and io_channel_write_blk64() functions are
3078 now functions instead of C preprocessor macros to provide better
3079 forward compatibility.

3088 E2fsprogs is now more portable to Solaris.
3089 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
3091 * Scripts do not assume that /bin/true is always in /bin
3092 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
3093 * Flush stdio handles before calling setbuf(), since Solaris will
3094 discard any pending output to the stream.
3095 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
3096 picky about which C compiler can beused for SUSv3 conformance.
3097 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
3098 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
3099 Since we need some SUSv3 functions, consistently use SUSv3 so
3100 that e2fsprogs will build on Solaris using c99.
3101 * Solaris C99 does not support varargs C preprocessor macros
3102 * Solaris header files pollute the C namespace if in/netinet.h
3103 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
3105 * Solaris ships with a pathetically ancient shell in /bin/sh so we
3106 avoid the use of various more avanced shell constructs such as $().
3108 The "make rpm" command will now take some extra configure optiosn from
3109 the build environment without needing to patch the source tree.
3111 The ext2fs_add_dir_block() function will now grow the dblist more
3112 aggressively as an optimization to avoid copying the array too often.
3114 The e2fsck_write_bitmaps() will write the block and inode bitmaps
3115 together instead of in two passes.
3118 E2fsprogs 1.41 (July 10, 2008)
3119 ==============================
3121 Add support for ext4 filesystem features, in particular extents,
3122 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
3123 support for checking journal checksums. Debugfs will print new
3124 superblock and inode fields that were defined for ext4. For example,
3125 the nanosecond and i_version fields of an inode, and the
3126 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
3127 Note: Resize2fs doesn't currently support the combination of flex_bg
3128 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
3130 Tune2fs can support migrating a filesystem from using 128 byte inodes
3131 to 256 byte inodes, so it can take advantage of the full features of
3134 Add support for "undo" support. E2fsck and mke2fs can optionally
3135 record an undo log which can replayed by the program e2undo.
3137 E2fsck could damage a filesystem by trying to relocate inode tables
3138 due to corrupted block group descriptors, where the attempted inode
3139 table relocation would do far more harm than good. E2fsck has been
3140 fixed to detect this these sorts of corrupted block group descriptors
3141 much earlier in e2fsck processing, so it can try to use the backup
3142 superblock and block group descriptors first. This should be a much
3143 better strategy for recovering these types of corrupted filesystems.
3144 (Addresses Sourceforge Bug: #1840291)
3146 E2fsck will display a more understandable message when the last check
3147 field in the superblock is in the future. (Addresses Debian Bug:
3150 E2fsck now performs more extensive and careful checks of extended
3151 attributes stored in the inode.
3153 Enhance mke2fs to print a more explanatory error message when
3154 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
3157 Fix mke2fs to use a default block size of 4k when formatting an
3158 external journal device. This is done by using a fixed filesystem
3159 type list that consists only of the single filesystem type "journal"
3160 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
3161 Debian Bug: #488663)
3163 Speed up how mke2fs writes the journal data blocks by writing the disk
3164 blocks in larger chunks.
3166 Fix blkid handling of stale devices. Fix a bug which could cause a
3167 core dump while garbage collecting the blkid cache, and assure that
3168 blkid_find_dev_with_tag() never returns a non-existent device. Also,
3169 if a filesystem is found at a new /dev location, eliminate any
3170 duplicate stale entries which can not be verified.
3171 (Addresses Debian Bugs: #487758, #487783)
3173 Add more paranoid checks for LVM volumes and swap partitions in
3174 blkid's probe function, to reduce the chances of false positives.
3176 The mke2fs program now has a much more sophisticated system for
3177 controlling configuration parameters of a newly created filesystem
3178 based on a split filesystem and usage type system. The -t option to
3179 mke2fs was a deprecated alias to -c; it now specifies a filesystem
3180 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
3181 separated usage list. The filesystem type information and type
3182 information is used to extract configuration parameters from the
3183 /etc/mke2fs.conf file.
3185 The mke2fs program will no longer complain and request the -f option
3186 when the user tries to create a filesystem with greater than 2**31
3189 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
3190 adjust the mke2fs.conf file so filesystems for the Hurd are created
3191 with a blocksize of 4096 and inode size of 128, which is all it knows
3192 how to handle. (Addresses Debian Bug: #471977)
3194 Mke2fs will always make sure that lost+found always has at least 2
3195 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
3197 Resize2fs will now print the minimum needed filesystem size if given
3198 the -P option, and will resize the filesystem to the smallest possible
3199 size if given the -M option.
3201 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
3202 blocks are consumed during an off-line resize.
3204 The "ls" command in debugfs now supports the -p option, which causes
3205 it to quote the filenames so that spaces or tabs in directory entries
3206 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
3207 Sourceforge Feature Request: #1201667)
3209 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
3212 The chattr program will return a non-zero exit code in case of
3213 failures, and error messages can be suppressed with the -f option.
3214 (Addresses Red Hat Bugzilla: #180596)
3216 Fix a bug in badblocks which caused it to overrun an array and likely
3217 crash if more than 8 test patterns are specified using the -t option.
3218 (Addresses Debian Bug: #487298)
3220 Add support to badblocks to limit how quickly it reads from the disk
3221 drive (so it can be used for background scrubbing), and so it will
3222 abort after finding a given number of errors.
3224 Remove support for the legacy big-endian filesystem format which only
3225 existed on extremely long-dead PowerPC kernels almost a decade ago.
3227 Remove MASIX support from e2fsprogs.
3229 Add I/O statistics reporting to e2fsck.
3231 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
3234 Fixed various Debian packaging issues --- see debian/changelog for
3235 details. (Addresses Debian Bugs: #487443, #487675, #490003)

3256 Clean up the badblocks group so to make it more portable and robust.
3258 Avoid using predictable filenames in /tmp in blkid's regression test
3259 suite. Also remove bashism's in the regression test script.
3261 If the configure script is given --with-diet-libc, don't use thread
3262 local storage, since diet libc doesn't support TLS. (Addresses
3263 Sourceforge Bug: #2000654)
3265 Fix the blkid regression test suite to tolerate older versions of
3266 mkswap that don't support the -U option.
3268 A few library routines have been converted to support 64-bit block
3269 numbers; in particular, the I/O manager functions, the test_io,
3270 inode_io, and unix_io managers have all be converted to support 64-bit
3273 Debugfs can now be extended for use by test programs. See
3274 lib/ext2fs/extents.c for an example for how it can be used. The test
3275 program links against the debugfs object files, and provides
3276 additional commands by defining an auxiliary libss command table.
3278 The lazy_bg filesystem feature, which was only used by developer's
3279 testing, has been removed since it has been largely supplanted by
3280 uninit_bg. This also simplifies the code.
3283 E2fsprogs 1.40.11 (June 17, 2008)
3284 =================================
3286 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
3287 percentage of reserved blocks. (Addresses Debian Bug: #452639)
3289 Updated Spanish and Catalan translations.
3291 Fixed various Debian packaging issues --- see debian/changelog for
3292 details. (Addresses Debian Bugs: #483962, #483023)
3294 Add detection for ZFS volumes to the libblkid library.
3296 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3297 (Addresses Debian Bug: #486463)
3302 Fix marginal C code in probe_lvm2() function to the blkid library more
3303 portable for older compilers.
3305 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
3307 Fix ext2fs_swap{16,32,64} functions so they can be used by external
3308 applications on big-endian machines. (Addresses Debian Bug: #484879)
3311 E2fsprogs 1.40.10 (May 21, 2008)
3312 ================================
3314 When deciding whether or not to revalidate a blkid cache entry, if the
3315 device's mtime is newer than the last time the cached entry was
3316 validated, force a revalidation.
3318 Fix a potential data corruption bug in e2fsck in the journal replay.
3319 The chances of this is happening is extremely remote, especially the
3320 default data=ordered or data=writeback modes. However, if a block
3321 which has been journalled starts with the first four bytes 0xc03b3998,
3322 when e2fsck replays the journal, those four bytes will be replaced
3323 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
3324 metadata to begin with those fatal 4 byte sequence, and unless
3325 data=ordered mode is in use, data blocks are never journaled.
3327 Updated German, Dutch, Sweedish, and Vietnamese translations.
3332 Fixed various Debian packaging issues --- see debian/changelog for
3335 Remove default sizes of types when cross compiling, since autoconf
3336 2.50 can figure this out automatically now.
3339 E2fsprogs 1.40.9 (April 27, 2008)
3340 =================================
3342 SuSE's security team audited uuidd and came up with a few minor
3343 issues. None of them are serious given that uuidd runs setuid as a
3344 unprivileged user which has no special access other than libuuid
3345 directory, but it's good to get them fixed.
3347 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
3348 work correctly with in-inode extended attributes.
3350 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
3353 Debugfs will avoid using a pager if the standard output is not a tty.
3355 Fix debugfs and tune2fs to correctly handle daylight savings time when
3356 parsing a time string.
3358 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3360 Fix fsck completion bars when multiple filesystems were being checked
3361 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
3362 #203323, Addresses Sourceforge Bug: #1926023)
3364 Fix fsck so that progress information is sent back correctly when
3365 multiple filesystems are being check and the output of fsck is being
3366 redirected to a file descriptor. Also, include the device name (w/o
3367 spaces) in the progress information sent back via a file descriptor.
3368 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
3371 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.

3374 signal to its child process.
3376 Fix mke2fs's creation of are resize inode when there is a non-standard
3377 s_first_data_block setting.
3379 Fix bug in blkid when run by an unprivileged user; most devices were
3380 not reported correctly. 9Addresses Launchpad Bug: #220275)
3382 Mke2fs will not allow the logically incorect combination of
3383 resize_inode and meta_bg, which had previously caused mke2fs to create
3384 a corrupt fileystem.
3386 Fix fsck in German locales so that a 'j' means yes.

3393 Fixed various Debian packaging issues --- see debian/changelog for
3396 Update valgrind options in test_script to work with valgrind 3.2.3

3405 Fix build system so that if texinfo is not installed, it won't print a
3406 (harmless) error message.
3409 E2fsprogs 1.40.8 (March 13, 2008)
3410 =================================
3412 Fixed e2image -I so it works on image files which are larger than 2GB.
3414 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
3415 the size is larger than the number of blocks found in the inode, don't
3416 try to allocate extra empty blocks at the end of the directory to make
3417 up the difference; there's no point to doing that. In addition, if
3418 the size is not a multiple of a blocksize, always fix it.
3420 E2fsck handled a pass 2 "should never happen error" by not giving
3421 enough information and then core dumping. Unfortunately, it was all
3422 too easy to trigger the "should never happen" situation if a
3423 directory's inode size was not correct. This has been fixed, but
3424 e2fsck has also been taught how to handle this situation more
3425 gracefully, by simply removing the inode hash tree information, so
3426 that it can be rebuilt again after e2fsck's pass 3. (Addresses
3427 Launchpad Bug: #129395)
3429 Resize2fs had a bug resizing large inodes with extended attributes
3430 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
3431 completely on big-endian systems such as PowerPC. The bug should be
3432 completely fixed now. Yay for regression test suites. (Addresses Red
3433 Hat Bugzilla: #434893)
3435 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
3436 translations. Many thanks to Philipp Thomas from Novell for stepping
3437 up to become the new German translation maintainer! (Addresses Debian
3438 Bugs: #302512, #370247, #401092, #412882).

3441 make it clear that it is just clearing the HTREE information, not the
3444 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3449 Add new functions, ext2fs_dblist_get_last() and
3450 ext2fs_dblist_drop_last(), which allows the caller to examine the last
3451 directory block entry added to the list, and to drop if it necessary.
3453 Fixed a portability problem in libblkid with DJGPP.
3455 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
3456 to Philipp Thomas for pointing this out.
3458 If the info files are not built, change "make install" so it doesn't
3459 fail with an error code.
3462 E2fsprogs 1.40.7 (February 28, 2008)
3463 ====================================
3465 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
3466 depreciate the -s option, since it can result in filesystems which
3467 e2fsck can't fix easily. There are very good reasons for wanting to
3468 disable sparse_super; users who wants to turn off sparse_super can use
3469 debugfs. (Addresses Sourceforge Bug: #1840286)
3471 Add missing options to mke2fs's usage message. (Addresses Sourceforge
3474 Fix bug in resize2fs when large (greater than 128 byte) inodes are
3475 moved when a filesystem is shrunk; it was only moving the first 128
3476 bytes, so extended attributes were not getting moved. (Addresses Red
3477 Hat Bugzilla: #434893)
3479 E2fsck now prints an explicit message when the bad block inode is
3480 updated, to avoid confusion about why the filesystem was modified.
3481 (Addresses Sourceforge Bug: #756460)
3483 Allow mke2fs and tune2fs manipulate the large_file feature.
3484 Previously we just let the kernel and e2fsck do this automatically,
3485 but e2fsck will no longer automatically clear the large_file feature.
3486 It still isn't really necessary to worry about this feature flag
3487 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
3490 Suppress message about an old-style fstab if the fstab file is empty.
3491 (Addresses Debian Bug: #468176)
3493 Fix (really minor) bug in debugfs's find_free_block so it avoids
3494 reporting a free block more than once if there are too few free blocks
3495 in the filesystem. (Addresses Sourceforge Bug: #1096315)
3497 Change e2fsck to no longer clear the LARGE_FILES feature flag
3498 automatically, when there are no more > 2GB files in the filesystem.
3499 It's been almost a decade since there have been kernels that don't
3500 support this flag, and e2fsck clears it quietly without telling the
3501 user why the filesystem has been changed.
3503 Fix bug which could cause libblkid to seg fault if a device mapper
3504 volume disappears while it is being probed. (Addresses RedHat
3507 Inhance e2fsck's reporting of unsupported filesystem feature flags.

3510 Fix option syntax in dumpe2fs for explicit superblock and blocksize
3511 parameters. What was currently documented in the man page has been
3512 broken for some time, due to getopt() implementation changes. The
3513 option sytax has been changed to one which is can be more portable
3514 supported and which is consistent with the format for extended options
3515 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)

3549 Fixed various Debian packaging issues --- see debian/changelog for
3550 details. (Addresses Debian Bug: #466929)
3552 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
3553 partially filled-in filesystem object on an error, so that e2fsck can
3554 print more intelligent error messages.
3556 Add a new function e2p_edit_feature2() which allows the caller to
3557 specify which feature flags are OK to set or clear, and which returns
3558 more specific information about feature flags which are not allowed to
3561 Set the C locale in the test_script driver since it uses [A-Za-z].
3562 (Addresses Sourceforge Bug: #1890526)
3564 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
3567 Change configure.in to avoid using the 'dc' command unless it is
3568 absolutely needed. (i.e., when using parsing a WIP-style version
3569 number) (Addresses Sourceforge Bug: #1893024)
3571 Add portability checks to support compilation under DJGPP.
3573 Update to the latest samba tdb code before the LGPLv3 change, which
3574 fixes a realloc() leak on failure.
3576 Fix memory leak in ext2fs_alloc_block().
3578 Fix makefile dependency issues for various install targets.
3579 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
3581 Improve descriptions for the r_move_itable and r_resize_inode tests.
3584 E2fsprogs 1.40.6 (February 9, 2008)
3585 ===================================
3587 Add support for returning labels for UDF filesystems in the blkid
3590 Fix bug in the blkid library where cached filesystems was not being
3591 flushed when opening USB devices returned the error ENOMEDIUM.
3592 (Addresses Debian Bug: #463787)
3594 Added logic to the blkid library to automatically choose whether a
3595 filesystem should be mounted as ext4 or ext4dev, as appropriate.
3597 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
3599 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
3600 configured with --enable-jbd-debug.
3602 Document the BLKID_FILE environment variable in the libblkid man page
3607 Update e2fsprogs translation template and Vietnamese and Czech translations
3609 Fixed various Debian packaging issues --- see debian/changelog for
3610 details. (Addresses Debian Bugs: #436058)
3612 Don't try to create $DESTDIR/etc/init.d as part of make install as we
3613 don't install the init.d script (and it's not the recommended way to
3614 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
3616 Use thread local storage to fix a theoretical race condition if two
3617 threads try to format an unknown error code at the same time in the
3621 E2fsprogs 1.40.5 (January 27, 2008)
3622 ===================================
3624 Fix a potential overflow big in e2image if the device name is too
3627 Mke2fs will now create new filesystems with 256 byte inodes and the
3628 ext_attr feature flag by default. This allows for much better future
3629 compatibity with ext4 and speeds up extended attributes even on ext3
3632 Teach e2fsck to ignore certain "safe" filesystem features which are
3633 set automatically by the kernel. Having the kernel set features
3634 automagically behind the user's back is a bad idea, and we should try
3635 to break the kernel of this habit, especially for the newer ext4
3636 feature flags. But for now, we will try to avoid needless full checks
3637 which can annoy users who are doing fresh installs.
3639 Add support in tune2fs and mke2fs for making a filesystem as being "ok
3640 to be used with test kernel code". This will be needed for using test
3641 filesystems with the latest ext4 kernel code.
3643 Change e2fsck -fD so that it sorts non-htree directories by inode
3644 numbers instead of by name, since that optimizes performances much
3645 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
3647 If e2image fills the disk, fix it so it exits right away instead of
3648 spewing large numbers of error messages.
3649 (Addresses-Sourceforge-Feature-Request: #606508)
3651 If ftruncate64() is not available for resize2fs, let it use ftrucate()
3652 instead, but have it check to see if the size would get truncated, and
3653 skip calling ftruncate in that case.
3655 Add support for detecting HFS+ filesystems in the blkid library.
3657 Add supprt in the blkid library for ext4/ext4dev filesystems.
3659 Fix a bug in blkid where it could die on a floating point exception
3660 when presented with a corrupt reiserfs image.
3662 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
3663 such that UUID string is a fixed length.
3665 Add sample python bindings for the uuid library to the contrib
3666 directory. (Addresses-Sourceforge-Patches: #778817)
3668 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
3669 will work with large files. (Addresses Sourceforge Feature Request:
3670 #1257500 and Sourceforge Support Request: #1253511)
3672 Allow the debugfs 'undel' command to undelete an inode without linking
3673 it to a specific destination directory, since this might require
3674 allocating blocks that could overwrite some yet-to-be-recovered
3675 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
3677 Update Swedish translations from the Translation Project.
3682 Fix configure handling of --sbindir (which should rarely be used, but
3683 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
3686 Updated e2fsprogs.spec file to include a new uuidd package
3688 Use pkg-config to determine where to find the devmapper library so we
3689 can find out where it is located on different distributions.
3691 Fix Makefile race so that "make -j3 distclean" works correctly
3693 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
3694 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
3697 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3699 Fixed various Debian packaging issues --- see debian/changelog for
3700 details. (Addresses Debian Bugs: #459403, #459475, #459614)
3702 Remove the --enable-dynamic-static configure option, and build e2fsck
3703 dynamically by default. If the user wants e2fsck.static, he/she will
3704 need to build it via "make -C e2fsck e2fsck.static"
3706 Fix various build warnings due to missing prototypes.

3710 E2fsprogs 1.40.4 (December 31, 2007)
3711 ====================================
3713 Improve time-based UUID generation. A new daemon uuidd, is started
3714 automatically by libuuid if necessary. This daemon is setuid to allow
3715 updates to /var/lib/libuuid, so the clock sequence number can be
3716 stored and so if the clock is set backwards, it can be detected.
3717 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
3720 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
3721 superblocks. This avoids e2fsck from concluding that a full
3722 filesystem check is required before backing up the superblock due to
3723 changes in the feature flags. (Addresses Debian Bug: #454926)
3725 Fix fsck to only treat the '#' character as a comment at the beginning
3726 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
3727 will cause fsck to issue an bogus warning message.
3728 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
3730 Format control characters and characters with the high eighth bit set
3731 when printing the contents of the blkid cache, to prevent filesystems
3732 with garbage labels from sending escape sequences to the user's screen
3733 that might, for example place it in graphics mode. (Addresses Ubuntu
3736 Fix sign-extension problem on 64-bit systems in in the com_err
3737 library. (Addresses Sourceforge Bug: #1809658)
3739 Avoid division by zero error when probing an invalid FAT filesystem in
3740 the blkid library. (Addresses Sourceforge Bug: #1831627)
3742 Update Dutch, Polish, and Vietnamese translations from the Translation
3743 Project. Remove the Rwandan translation upon advice of the
3744 Translation Project.
3749 Fix the libss "make check" regression test so that it works if the
3750 current directory is not in the user's path or if the libss shared
3751 library is not installed. (Addresses Sourceforge Bug: #1848974)
3753 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3754 (Addresses Debian Bugs: #444883, #441872)
3756 Fixed various Debian packaging issues --- see debian/changelog for
3757 details. (Addresses Debian Bugs: #437720, #451172, #458017)

3762 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
3765 E2fsprogs 1.40.3 (December 5, 2007)
3766 ===================================
3768 Fix a potential security vulnerability where an untrusted filesystem
3769 can be corrupted in such a way that a program using libext2fs will
3770 allocate a buffer which is far too small. This can lead to either a
3771 crash or potentially a heap-based buffer overflow crash. No known
3772 exploits exist, but main concern is where an untrusted user who
3773 possesses privileged access in a guest Xen environment could corrupt a
3774 filesystem which is then accessed by the pygrub program, running as
3775 root in the dom0 host environment, thus allowing the untrusted user to
3776 gain privileged access in the host OS. Thanks to the McAfee AVERT
3777 Research group for reporting this issue. (Addresses CVE-2007-5497.)
3779 Fix hueristics in blkid which could cause a disk without partitions to
3780 be incorrectly skipped when a loopback device is present. (Addresses
3781 Red Hat Bugzilla #400321.)
3783 Fix e2image so that in raw mode it does not create an image file which
3784 is one byte too large.
3786 Change mke2fs's usage message so it recommends the preferred -E option
3787 instead of the deprecated -R option.
3789 Enhance the blkid library so it will recognize squashfs filesystems.
3790 (Addresses Red Hat Bugzilla #305151.)
3792 Enhance e2fsck so it will force the backup superblocks to be backed up
3793 if the filesystem is consistent and key constants have been changed
3794 (i.e., by an on-line resize) or by e2fsck in the course of its
3797 Enhance blkid's detection of FAT filesystems; so that USB disks with
3798 only a single bootable partition will not get missed.
3800 E2fsck will no longer mark a filesystem as invalid if it has time
3801 errors (i.e., if superblock mount time or last write time is in the
3802 future) and the user refuses to fix the problem.
3804 The Ubuntu init scripts don't properly set the system time correctly
3805 from hardware clock if the hardware clock is configured to tick local
3806 time instead of GMT time. Work around this as best as we can by
3807 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
3808 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
3811 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
3812 Hat Bugzilla #151533.)
3814 Fix e2fsck so that if the superblock is corrupt, but still looks
3815 vaguely like an ext2/3/4 superblock, that it automatically tries to
3816 fall back to the backup superblock, instead of failing with a hard
3819 Make the e2fsprogs program more robust so that they will not crash
3820 when opening a corrupt filesystem where s_inode_size is zero.
3822 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
3823 arguments are detected as such and the parse error is reported to the
3824 user. (Addresses Debian Bug #435381.)
3826 Change e2fsck so it will not complain if a file has blocks reallocated
3827 up to the next multiple of a system's page size.
3829 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
3830 about (valid) filesystems where the inode table extends to the last
3831 block of the block group. (Addresses Red Hat Bugzilla #214765.)
3833 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
3834 allocating inode tables for some relatively rare odd disk sizes.
3835 (Addresses Red Hat Bugzilla #241767.)
3837 Add Catalan translation and update Dutch and Swedish translations
3838 from the Translation Project.
3840 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
3841 still had an issue when trying to figure out whether we need to
3842 byte-swap fast symlinks that contained extended attributes.
3844 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3845 (Addresses SourceForge Bug #1821333.)
3851 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
3853 Add "make check" to the RPM spec file
3855 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
3856 works correctly when the prefix is not the root directory.
3858 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
3859 clena up after themselves by deleting the test.img temporary file
3860 after completing the test.
3862 Fixed a corner case bug ext2fs_unlink() when trying to delete the
3863 first directory entry in a directory block and the last directory
3864 entry in the previous directory block is not in use. Fortunately
3865 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
3866 places where it is extremely unlikely to run into this corner case.
3868 Fix missing dependency which would cuase parallel builds to fail.
3869 (Addresses Sourceforge Bug #1842331.)
3871 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
3872 calling open(O_CREATE) with a missing mode parameter.
3874 Fix the test_ss.c in lib/ss so it can be used as an example
3875 application program for the library as well as a regression test
3878 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
3879 are properly passed back up through the call stack.
3881 E2fsprogs 1.40.2 (July 12, 2007)
3882 ================================
3884 A recent change to e2fsck_add_dir_info() to use tdb files to check
3885 filesystems with a very large number of filesystems had a typo which
3886 caused us to resize the wrong data structure. This would cause a
3887 array overrun leading to malloc pointer corruptions and segfaults.
3888 Since we normally can very accurately predict how big the the dirinfo
3889 array needs to be, this bug only got triggered on very badly corrupted
3892 Fix a bug in e2fsck which caused it to incorrectly salvange
3893 directories when the last entry's rec_len is bogusly too big. This
3894 resulted in a nonsense filesystem corruption to be reported, and
3895 required a second run of e2fsck to fully fix up the directory.
3897 Update tune2fs man page to include more discussion of reserved blocks
3898 (Addresses Launchpad bug #47817)
3900 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
3904 E2fsprogs 1.40.1 (July 7, 2007)
3905 ===============================
3907 Fix bug which could cause libblkid to loop forever. When revalidating
3908 a partition where there is obsolete information in /etc/blkid.tab, we
3909 end up freeing a the type tag without clearing dev->bid_type, causing
3910 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
3912 The Turkish translation has a bug in it where it has the translation
3913 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
3914 @E, recursively, forever, until the stack fills up and e2fsck core
3915 dumps. We fix this by making e2fsck stop @-expansions after a
3916 recursive depth of 10, which is far more than we need.
3917 (Addresses Sourceforge Bug: #1646081)
3919 Compile the default mke2fs.conf into mke2fs program. People are
3920 getting surprised by mke2fs creating filesystems with different
3921 defaults than earlier versions of mke2fs if mke2fs.conf is not
3922 present. So we now create a built in version of mke2fs.conf file
3923 which is used by mke2fs if the /etc/mke2fs.conf is not present.
3924 (Addresses SourceforgeBug: #1745818)
3926 Improve the config/parse_types.sh helper script. Fix a potential
3927 security problem if e2fsprogs is built as root (as Gentoo does!). In
3928 addition fix the script and how it is called from the configure script
3929 so that it does the right thing when cross-compiling. (Fixes Gentoo
3932 Update Vietnamese, French, and Dutch PO files from the Translation
3933 Project. Also created a new e2fsprogs.pot file for translator.
3935 Fix bogus strip permission errors when building under Debian. When
3936 building the e2fsprogs dpkg's, the dh_strip command emits a large
3937 number of error messages caused by the permissions not being right.
3938 So run dh_fixperms before running dh_strip.
3943 Add new function: profile_set_default(). This function sets the value
3944 of the pseudo file "<default>". If the file "<default>" had
3945 previously been passed to profile_init(), then def_string parameter
3946 will be parsed and used as the profile information for the "<default>"
3949 Fix mk_cmds's error reporting so that it is unambiguous that it is the
3950 mk_cmds script which is generating the error. (Obviates Gentoo patch:
3951 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
3953 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
3954 priority" environment variable that overrides all others, where as
3955 LANG is the lowest priorty environment variable. If LC_ALL is set, it
3956 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3957 the all the rest are set. This will assure that the locale when
3958 running the test suites is the "C" locale. (Obviates Gentoo patch:
3959 e2fsprogs-1.38-tests-locale.patch)
3962 E2fsprogs 1.40 (June 29, 2007)
3963 ==============================
3965 Fix divide by zero error in blkid's NTFS probing logic.
3967 Add new blkid -g option which causes the blkid cache to be garbage
3970 Fix a bug in libblkid which could cause the internal field bid_type to
3971 become corrupted. Fortunately bid_type isn't used much, and bid_label
3972 and bid_uuid is only used by debugging code, so the impact of this bug
3975 Mke2fs will now store the RAID stride value when a filesystem is
3976 created with a requested RAID stride, and then use it automatically in
3979 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3980 isn't too big. In some cases Lustre users have tried specifying an
3981 inode size of 4096 bytes, while keeping an inode ratio of one inode
3984 Improve sanity check in e2fsck's algorithm for finding a backup
3985 superblock, so that it won't accidentally find a superblock that was
3986 located in the journal, and then later reject it as being not a valid
3989 Fix e2fsck get_size logic so that it will work with the Linux floppy
3990 driver. The Linux floppy driver is a bit different from the other
3991 block device drivers, in that if the device has been opened with
3992 O_EXCL, it disallows another open(), even if the second open() does
3993 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
3995 Fix error checking of badblock's last-block and start-block arguments.
3996 (Addresses Debian Bug: #416477)
3998 Fix e2fsck so that it doesn't overwrite the backup superblocks when
3999 recovering a journal until the master superblock has been confirmed as
4002 Change the blkid library to be much more paranoid about concluding
4003 that a partition contains an NTFS filesystem, and fetch the UUID and
4004 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
4007 Factor out the code which sets the default journal size and move it
4010 Enhance e2fsck so it will recreate the ext3 journal if the original
4011 journal inode was cleared to due it being corrupt after finishing the
4014 Fix e2fsck so that it updates the journal inode if it is corrupted and
4015 the backup journal information from the superblock was successfully
4016 used to recover the filesystem.
4018 Fix e2fsck so that it checks all of the blocks in the journal inode
4019 for validity. The original code only checked the direct blocks to
4020 make sure the journal inode was sane. Unfortunately, if some or all
4021 of the indirect or doubly indirect blocks were corrupted, this would
4024 Add support in blkid to detect LUKS encrypted partitions.
4026 Add extra sanity checks for extended attributes in the case where the
4027 size is zero but the offset is very large.
4029 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
4030 and ext2fs_get_next_inode_full().
4032 Clarify the copyright licenses used by the various libraries in
4033 the top-level COPYING file (Red Hat Bugzilla: 166058)
4035 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
4037 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
4039 Remove check in e2fsck which requires EA's in inodes to be sorted;
4040 they don't need to be sorted, and e2fsck was previously wrongly
4041 clearing unsorted EA's stored in the inode structure.
4043 Allow mke2fs or tune2fs to create a substantially larger journal (up
4044 to 10,240,000 blocks).
4046 Fix MD superblock detection, and make sure the correct UUID is
4047 reported from the MD superblock.
4049 Fix a signed vs. unsigned bug in debugfs.
4051 Enhance debugfs's date parser so that it accepts integer values.
4053 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
4054 file with multiply claimed blocks is hard linked. or not at all if the
4055 root directory contains shared blocks
4057 Enhance debugfs so it can modify the block group descriptors using the
4058 command set_block_group_descriptor.
4060 Improve e2fsck's reporting of I/O errors so it's clearer what it was
4061 trying to do when an error happens
4063 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
4064 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
4065 #232663 and LTC Bugzilla: #27634)

4081 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
4082 field on the first pass.
4084 Fix e2fsck to set the file type of the '..' entry when connecting
4085 a directory to lost+found. (Addresses Lustre Bug: #11645)
4087 Enhance e2fsck to recover directories whose modes field were corrupted
4088 to look like special files. This is probably only useful in
4089 artificial test cases, but it will be useful if we ever do the "inodes
4090 in directory" idea for ext4.
4092 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
4095 Fix resize2fs parsing of size parameter (in sector units). This was
4096 actually a bug in libe2p's parse_num_blocks() function. When handling
4097 the 's' suffix, it was ignoring the blocksize information passed in
4098 from the caller and always interpreting the number in terms of a 1k
4099 blocksize. (Addresses Debian Bug: #408298)
4101 There was a floating point precision error which could cause e2fsck to
4102 loop forever on really big filesystems with a large inode count.

4105 Fix memory leak in ext2fs_write_new_inode()
4107 Add support for using a scratch files directory to reduce e2fsck's
4108 memory utilization on really big filesystems. This uses the TDB
4109 library. See the [scratch_files] section of the e2fsck.conf man page

4116 (Addresses Debian Bug: #371869)
4118 Allow debugfs and dumpe2fs to support fs features under development.
4120 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
4121 ext2fs_open() , which allows application to open filesystes with features
4122 which are currently only partially supported by e2fsprogs.
4124 Allow unix_io to support offsets greater than 2G (Addresses
4125 SourceForge Bug: #1547922)
4127 Fixed overflow and signed/unsigned problems caused by the number of
4128 blocks or inodes exceeding 2**31 or being close to 2**32-1.
4130 Add support for unsigned directory hash calculations with hints in the
4131 superblock to fix cross-architectural portability for htree
4132 directories with filenames where the high 8th bit is set. (Addresses
4135 Fix resize2fs so that it gives user-intelligible error messages if the
4136 filesystem or the kernel does not support on-line resizing.
4137 (Addresses Debian Bug: #380548)
4139 Require mke2fs -F -F for really dangerous operations, since -F is
4140 needed for less dangerous operations such as creating filesystems
4141 images in regular files, or creating filesystems on whole block
4142 devices. These relatively innocuous usages should NOT be confused
4143 with running mke2fs on an apparently-mounted or in-use filesystem.
4145 Allow the default inode size to be specified into the mke2fs.conf
4148 Make the smallest default journal size is big enough so that on-line
4149 resizing should always work.
4151 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
4154 Fix debugfs coredump when lsdel is run without an open filesystem
4155 (Addresses Debian Bug: #378335)
4157 Fix debugfs display bug us that bytes that have the high bit set are
4158 displayed as "ec" instead of "ffffffec".
4160 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
4162 Device mapper scanning wasn't working in the blkid library because the
4163 pathnames had an extra "/dev" when they were being probed.
4165 Add GFS/GFS2 support to the blkid library.
4167 Fix blkid support of empty FAT filesystem labels.
4169 Avoid recursing forever (or for a long time) when the blkid library
4170 searches for a device and there are symlinks to directories in /dev.
4172 Avoid unaligned halfword access in blkid when accessing FAT
4173 superblocks, as this will cause Sparc/Solaris systems to throw a
4176 The latest devmapper libraries requires pthreads, add -lpthreads to
4177 the static link libraries for e2fsck.static if devmapper is enabled.
4178 (Addresses Debian bug: #388718)
4180 Improve the (non-installed, for experts only) findsuper program by
4181 printing the uuid and label from the superblocks, as well as the
4182 starting and ending offsets of the filesystem given the information in
4183 the superblock. Omit by default printing superblocks that are likely
4184 found in located in an ext3 journal unless an explicit -j option is
4187 Updated Spanish, French and Dutch translations and added Catalan
4188 translation. (Addresses Debian bug: #411562)
4190 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
4191 determining a partition's size, since binary searching to determine
4192 the device doesn't work on FreeBSD.
4194 Documentation about UUID's is available in enough places, and it's
4195 awkward to deal with debian-legal's insanities. So I'm caving in the
4196 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
4197 don't have do the dfsg tarball. Also remove the rule that only tried
4198 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
4199 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
4201 Fix the info-dir line so that the menu name does not contain a .info
4202 prefix. First of all, it's ugly, secondly, it causes the install-info
4203 command to fail to remove the com_err info file from the
4204 /usr/share/info/dir file when the comerr-dev package is removed and
4205 purged. (Addresses Debian Bug: #401711)
4207 Fixed spelling mistakes, typos, and otherwise clarified man pages.

4212 #408352, #415560, #399155)
4218 E2fsck now supports the %It expansion when printing a problem report.
4219 It will print the type of the inode in the problem context.
4221 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
4222 (Addresses Sourceforge Bug: #1565561)
4224 Remove unused variables and other lint/gcc -Wall cleanups
4226 Add check to ext2fs_get_device_size() so it will return EFBIG for for
4227 filesystems contained in regular files where the filesystem image size
4228 is returned by stat64().
4230 Set local environment variables to C so mk_cmds and compile_et always
4231 work. (Addresses SourceForge Bug: #1532177)
4233 Added the 64-bit byte swapping function ext2fs_swab64().
4235 Added two new helper functions to prevent 2**31/2**32-1 overflow
4236 problems: ext2fs_div_ceil() and e2p_percent().
4238 Create new ext2fs library inline functions ext2fs_group_first_block()
4239 and ext2fs_group_last_block() in order to calculate the starting and
4240 ending blocks in a block group.
4242 Create the generated files read-only to remind developers not to edit them.
4244 Add support for autoconf 2.60 (with backwards compatibility for older
4245 versions of autoconf).
4247 Added an "make rpm" target to top-level Makefile
4249 Added various FreeBSD portability fixes.
4251 Exclude mercurial files from the RPM build tree to speed up copy/build.
4253 Use root_sysconfdir to define the locations of mke2fs.conf and
4254 e2fsck.conf instead of using a hard-coded /etc pathname.
4256 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
4258 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
4260 If diff -u is supported, use it to report test failures.
4262 Updates/improvements to RPM spec file
4264 Add on-disk format definitions for the following new features:
4265 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
4266 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
4267 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
4269 Add a new make target "checked-failed" in the tests directory which
4270 reruns any failed tests
4272 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
4274 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
4275 pointer dereferences, memory leaks, etc. None were security-criticial
4278 Fix up usage and decrement error messages in the test_icount program
4280 Add debugging code to the com_err library; if the environment variable
4281 COMERR_DEBUG is set to 1, print out debugging messages as error tables
4282 are added and removed from the com_err library. If the
4283 COMERR_DEBUG_FILE environment variable is set (and the process is not
4284 setuid) the debugging messages may be redirected to a file.
4286 Change all of the e2fsprogs programs to use the newer add_error_table()
4287 and remove_error_table() interfaces instead of the much older
4288 initialize_*_error_table() function.
4290 Add TDB support into the ext2fs library. This allows us to have a
4291 guaranteed library we can count on always being present so we can
4292 store data in an on-disk database.
4294 Add support for using TDB to store the icount data, so we don't run out
4295 of memory when checking really large filesystems.
4297 Change the regression test suite so that it skips empty test directories.
4299 Define the l_i_iversion field in ext2_inode. The l_i_version field is
4300 now defined from the old l_i_reserved1 field in the ext2 inode. This
4301 field will be used to store high 32 bits of the 64-bit inode version
4304 Add Makefile production rule for e2fsprogs.spec in case it gets
4307 Add new function profile_get_uint() to allow for a clean way to fetch
4308 unsigned integers from the context.
4310 Add test to make sure the ext2 superblock structure is 1024 bytes.
4312 Fix typo in name of f_dup4 regression test
4314 Add new function blkid_gc_cache() which performs a garbage collection
4315 pass on the /etc/blkid.tab file.
4317 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
4318 general, only e2fsck (after the filesystem is clean), tune2fs, and
4319 resize2fs should change the backup superblocks by default. Most
4320 callers of ext2fs_open() should not be touching any superblock fields
4321 which require the backups to be touched.
4323 Add new function to libext2fs, ext2fs_default_journal_size(), which
4324 returns the default journal size.
4327 E2fsprogs 1.39 (May 29, 2006)
4328 =============================
4330 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
4331 between 2**31 and 2**32 blocks.
4333 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
4334 configure the filesystem features, blocksize, and inode_ratio for
4335 different filesystem types.
4337 Mke2fs will now create filesystems hash trees and on-line resizing
4338 enabled by default, based on the new /etc/mke2fs.conf file.
4340 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
4341 filesystem device node in exclusive mode to prevent accidents by
4342 system administrators. In the case of resize2fs and mke2fs, it will
4343 only use exclusive mode if the filesystem is not mounted.
4345 Fixed a bug in mke2fs which caused it to to fail when creating the
4346 resize inode for large filesystems. (Addresses Debian Bug #346580)
4348 When allocating space for the RAID filesystems with the stride
4349 parameter, mke2fs will now place each portion of the group's inode
4350 table right up after the superblock (if present) in order to minimize
4351 fragmentation of the freespace.
4353 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
4354 efficiently by writing the inode and block bitmaps in one pass, thus
4355 reducing the number of disk seeks required.
4357 Add support for on-line resizing to resize2fs.
4359 Fix blkid library so that logic to determine whether or not a device's
4360 cached information in /etc/blkid.tab needs to be verified or not
4361 doesn't get confused by a system clock which is insane (for example,
4362 if the battery is dead on a Macintosh running PPC Linux. (Addresses
4363 Red Hat Bug: #182188)
4365 The blkid library will now store the UUID of the external journal used
4366 by ext3 filesystems, so that in the future, the userspace mount binary
4367 can use this to find the location of the external journal and pass
4368 this information to the kernel.
4370 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
4371 control how various options should be handled. See the e2fsck.conf
4372 man page for more details. (Addresses Debian Bug: #150295)
4374 E2fsck now prints an explanatory message when delaying a filesystem
4375 check when the system is running on battery. (Addresses Debian Bug:
4378 E2fsck will detect if the superblock's last mount field or last write
4379 field is in the future, and offer to fix if so. (Addresses Debian Bug
4380 #327580) These problems will be fixed automatically in preen mode
4381 since Debian's boot sequence bogusly doesn't set the time correctly
4382 until potentially very late in the bootup process, and this can cause
4383 false positives which will cause users' systems to fail to boot.
4384 (Addresses Debian Bugs #343662 and #343645)
4386 E2fsck now checks to see if the superblock hint for the location of
4387 the external journal is incorrect, and if so, offer to update it.
4388 (Addresses Debian Bug: #355644)
4390 Fix e2fsck from segfaulting on disconnected inodes that contain one or
4391 more extended attributes. (Addresses Debian Bug: #316736, #318463)
4393 E2fsck will stop and print a warning if the user tries running a
4394 read/write badblocks test on a read-only mounted root filesystem.
4396 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
4397 C. Thompson for pointing these out; they were originally found using
4400 When resizing a file containing a filesystem, resize2fs will expand or
4401 truncate a file as necessary. (Addresses Debian Bug: #271607)
4403 Resize2fs will now automatically determine the RAID stride parameter that
4404 had been used to create the filesystem, and use that for newly created
4405 block groups. The RAID stride parameter may also be manually specified
4406 on the command line using the new -S option to resize2fs.
4408 Fix mke2fs so that it correctly creates external journals on
4409 big-endian machines (such as a S/390).
4411 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
4412 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
4413 Chambraud for pointing this out.)
4415 Dumpe2fs will now print the size of the journal (if present).
4417 Fix debugfs's set_inode_field command so it can properly set the frag,
4418 fsize, uid_high, gid_high, and author fields in the inode instead of
4419 silently failing, and so that setting the i_size actually sets i_size
4422 Add a new debugfs command, set_current_time, which sets fs->now so
4423 that regression test suites can repeatedly modify the filesystem's
4426 Fix a bug in debugfs's icheck which would incorrectly report the owner
4427 of an extended attribute block.
4429 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
4430 print a usage message when an illegal option character is given.
4432 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
4433 so it won't core dump. (Addresses SourceForge bug #1424311)
4435 Fix mklost+found so that it creates a full-sized directory on
4436 filesystems with larger block sizes.
4438 Fix a file descriptor leak in blkid library.
4440 Fix a display bug in "badblocks -sv" so that the done message properly
4441 clears the block number at the end of the test. (Addresses Debian Bug
4444 Allow fractional percentages to the -m option in mke2fs and tune2fs
4445 (Addresses Debian Bug: #80205)
4447 Use fstat/fstat64 in getsize.c if the the target is a regular file,
4448 instead of attempting to do a binary search. Fix some fd leaks in
4451 Add support for device mapper library to the blkid library to ensure
4452 that the "best" (i.e., leaf) device is probed by the blkid library.
4454 Fix the blkid library so that it notices when an ext2 filesystem is
4457 Improve the blkid's library VFAT/FAT detection; it now understands
4458 labels stored in the root directory, and is more paranoid about
4459 checking the FAT superblock values.
4461 Fixed a fd leak in the uuid library which was causing problems for the
4462 LVM tools. (Addresses Debian Bug: #345832)
4464 Add support for the reiser4 and software suspend partitions to the
4465 blkid library. Also add support for extract the label from iso9660
4468 Fix a compile_et bug which miscount the number of error messages if
4469 continuations are used in the .et file.
4471 Add extra sanity checks to protect users from unusual cirucmstances
4472 where /etc/mtab may not be sane, by checking to see if the device is
4473 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
4476 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
4477 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
4479 Fix use-after-free bug in e2fsck when finishing up the use of the
4480 e2fsck context structure.
4482 Fixed spelling mistakes, typos, and otherwise clarified man pages and
4483 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

4499 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
4500 Bugs: #360661, #360317)
4502 Fixed the Makefile so that they work correctly on newer versions of
4503 GNU make (i.e., 3.81).
4505 Add valgrind support to the regression test suites, and eliminate
4506 false positives from valgrind.
4508 Add a regression test suite for the blkid library.
4510 Fix a fencepost error in resize2fs caught by valgrind.
4512 Fix compiler warnings about missing memcpy prototypes.
4514 We no longer have the sparc assembly code in the header file any more,
4515 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
4516 break compiles on the sparc architectures when using gcc.
4518 In the libext2fs library, add the new field fs->now which if non-zero
4519 is used instead of the system time when setting various filesystem
4520 fields (last modified time, last write time, etc.)
4522 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
4523 ext2fs.h which is needed since the inline functions use memcpy().
4524 (Addresses Sourceforge Bug #1251062)
4526 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
4527 the build system when building files in the util directory which are
4528 needed during the build process. This avoids potential problems when
4529 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
4530 are not recognized as valid by the host compiler. (Addresses
4531 Sourceforge Bug #1261547)
4533 Clean up the blkid library by making the superblock and generic i/o
4534 functions to be more generic. Clean up interface to the probe
4535 function, and fix memory leak. Finallly, remove an unneeded reference
4536 to probe.h in the lib/blkid/resolve.c
4538 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
4539 of invalid block #'s.
4541 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
4542 indicate that the the function read/writes the memory location.
4544 Fix various gcc -Wall complaints.
4546 Add a dependency to make sure that the subdirectories are created
4547 before creating all of the object files, in order to address parallel
4548 build problem in the library Makefiles. (Addresses Sourceforge Bug:
4551 Add $(LDFLAGS) to the command line argument when generating an ELF or
4552 Solaris shared library, to allow cross-compile and other builds that
4553 might need to specify -L paths to needed libraries. (Addresses
4554 Sourceforge Bug #1261549)
4556 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
4557 intended for testing purposes. It allows an ext2/ext3 developer to
4558 create very large filesystems using sparse files where most of the
4559 block groups are not initialized and so do not require much disk
4560 space. Eventually it could be used as a way of speeding up mke2fs and
4561 e2fsck for large filesystem, but that would be best done by adding an
4562 RO_COMPAT extension to the filesystem to allow the inode table to be
4563 lazily initialized on a per-block basis, instead of being entirely
4564 initialized or entirely unused on a per-blockgroup basis.
4566 Fix backwards compatibility so e2fsprogs will better compile on Linux
4569 Make test scripts more robust against locale-related environment variables
4571 Fix type warning problem with sizeof() in ext2fs_open2().
4573 Fix type warning problem with time_t in debugfs.
4576 E2fsprogs 1.38 (June 30, 2005)
4577 ==============================
4579 Fix blkid's test programs (built with "make check") compile correctly
4580 even without "configure --enable-blkid-debug".
4582 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
4583 type aliasing rules on newer gcc compilers. (Addresses Red Hat
4586 Fix com_err library to make it more compatible with recent changes
4587 made to the com_err library in MIT Kerberos V5 version 1.4.
4588 (Addresses Sourcefroge Bug #1150146)
4590 General cleanup of messages printed by e2fsprogs programs for grammar,
4591 consistency, and to make life easier for translators. Fixed a few
4592 strings containing English that had not been marked as needing
4593 translations. Removed strings that do not need to be translated, to
4594 make life easier for translators.
4596 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
4597 test to see if a device appears to be in use instead of just relying
4598 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
4600 Fix portability problem in the filefrag program affecting platforms
4601 where the size of an integer is smaller than the size of a long.
4602 (Addresses Debian Bug #309655)
4604 Mke2fs will now use a larger journal by default for filesystems
4605 greater than 4GB. (128 MB instead of 32MB).
4607 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
4608 unless forced. This is to avoid signed vs. unsigned kernel bugs in
4609 block numbers that still need to be fixed.
4611 The blkid program has a new option which will more efficiently search
4612 for device when it is known (or expected) that only one matching
4613 device will be found in the system, such as when doing a lookup by
4616 Debian's e2fsprogs-specific initrd fragment will avoid including
4617 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
4618 and LD_LIBRARY_PATH, and filtering out libraries found in
4619 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
4621 Fixed a potential portability issue in the blkid programs for
4622 architectures where the char type is unsigned. (Addresses Sourceforge
4625 Fix a bug in filefrag so that it doesn't falsely count an extra
4626 discontinuity when the first block found is an indirect block.
4627 (Addresses Debian Bug #307607).
4629 Fix blkid's recognition of cramfs filesystems, and enhance it to be
4630 able to handle cramfs labels.
4632 Fix debugfs's stat command to not core dump when a filesystem is not
4635 Fix e2fsck's handling of error conditions caused by the resize inode
4636 claiming blocks that are also used by other inodes, a filesystem
4637 corruption which was commonly caused by a bug in Fedora Core 3's
4640 Fixed bug in filefrag which caused it to fail on non-ext2/3
4641 filesystems. (Addresses Debian Bug: #303509)
4643 If the superblock last mount time indicates that the system clock may
4644 not be accurate, then e2fsck will omit checking inodes' deletion time
4645 field for indications of a potential corrupted orphaned inode list.
4646 (Previously e2fsck only ommited these LOW_DTIME checks when the
4647 superblock's last write time looked insane.)
4649 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
4650 (Addresses Debian bug #302200)
4652 Make the blkid library more paranoid about being run from setgid
4653 programs, and to use __secure_getenv() from libc if it is available.
4655 Fixed spelling mistakes, typos, and otherwise clarified man pages.

4661 Fixed various Debian packaging issues --- see debian/changelog for
4667 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
4668 changed to take an unsigned int for the bit number. Negative bit
4669 numbers were never allowed (and didn't make any sense), so this should
4670 be a safe change. This is needed to allow safe use of block numbers
4671 greater than or equal to 2**31.
4673 The compile_et program will avoid recreating generated foo_err.c and
4674 foo_err.h files if no changes are necessary. The compile_et program
4675 will also atomically replace these files to avoid a potential parallel
4676 build race problem on SMP systems. (Addresses Sourceforge Bug:
4679 Added a new function to the blkid library, blkid_probe_all_new(),
4680 which only probes newly added disk devices, and change
4681 blkid_find_dev_with_tag() to use this function so that when a
4682 requested tag is not found, devices that were previously not checked
4683 are searched before searching all devices in the system.
4685 Added new functions to the blkid library, blkid_dev_set_search() and
4686 blkid_dev_has_tag().
4688 E2fsck's problem strings can now use @m and @n as abbrevations for
4689 "multiply-claimed" and "invalid", respectively.
4691 The e2fsprog.pot file now has an explanation of how the @-expansion
4692 and %-expansion works, and strings in e2fsck/problem.c which contain @
4693 characters now have comments in e2fsprogs.pot with the @-expansion to
4694 make life easier for translators.
4696 Fixed missing return values in the ext2fs library which could cause it
4697 to return random garbage in certain error conditions.
4699 Allow the current time to be overriden via the E2FSCK_TIME environment
4700 variable for use in regression tests.
4702 The test scrpit driver program now exits with a non-zero status if
4703 there any of its test that it ran failed.
4705 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
4708 Fixed "make check" so that it compiles correctly even when e2fsprogs'
4709 header files have not be installed in the system include directories.
4710 (Addresses Sourceforge Bug: #1180572)
4712 Fixed gcc -Wall nits.
4715 E2fsprogs 1.37 (March 21, 2005)
4716 ===============================
4718 Add support for checking the validity of Extended Attributes stored in
4721 Add support for dumping the contents of large inodes to debugfs,
4722 including the extended attributes stored in inodes.
4724 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
4725 when we create a new inode we make sure that the extra information in
4726 the inode (any extra fields in a large inode and any ea-in-inode
4727 information) is initialized correctly. This can take place when
4728 mke2fs creates the root and lost+found directory, when e2fsck creates
4729 a new root inode or a new lost+found directory, and when the user uses
4730 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
4731 create inode could inherit garbage (or old EA information) from a
4732 previously deleted inode.
4734 Fixed a bug in e2fsck so it would notice if a file with an extended
4735 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
4738 Added support to filefrag to detect files which are using the new
4739 experimental file extents format, and use the non-ext2 algorithm in
4740 that case. Fixed a bug to avoid reporting a false discontinuity if
4741 there is one or more unallocated blocks at the beginning of a file.
4743 Duplicated a check for noticing whether or not the number of blocks
4744 (given a certain blocksize) is greater than 2**32 when the
4745 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
4746 allows mke2fs to automatically use a larger blocksize when creating a
4747 filesystem on a very large device when run on systems that do not
4748 support BLKGETSIZE64.
4750 Fix the I18N build which was broken in e2fsprogs 1.36 because the
4751 build system had been switched to treat the .gmo files as shipped
4752 files (for backwards compatibility with systems that have older GNU
4753 I18N tools installed), but the gen_tarball.in script was still
4754 removing the .gmo files from the official source distribution.
4756 Fixed various Debian packaging issues --- see debian/changelog for
4757 details. (Addresses Debian Bugs ##296769, #299341)
4762 Added new functions to the e2p library which convert between a string
4763 and os_type: e2p_os2string() and e2p_string2os(), and used them to
4764 make the generated binaries more compact.
4766 Fixed a compile-time error on Darwin systems.
4768 Cleaned up the lib/ext2fs Makefile slightly.
4771 E2fsprogs 1.36 (February 4, 2005)
4772 =================================
4774 All of the patches that were applied to Fedore Core 3's
4775 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
4776 lot of bug fixes first. Users of Fedora Core 3 are strongly
4777 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
4779 Add support for filesystem with the online resizing via resize inode
4780 feature. Fixed numerous bugs from the Fedora patches. The Fedora
4781 patches also didn't bother to do any consistency checking on the
4782 resize inode, or add any tests to the regression test suite. The "-R
4783 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
4784 being listed in mke2fs's usage message. All of these shortcomings
4785 have been corrected.
4787 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
4788 program. In order to do this, the user must run the commands:
4790 debugfs -w /dev/hdXXX -R "features ^resize_inode"
4791 e2fsck -f /dev/hdXXX
4793 Optionally, the ext2prepare command can be used to re-enable online
4794 resizing after the filesystem has been fixed.
4796 The fsck program will now accept an optional filedescriptor argument
4797 to the -C option. (The Fedora version of this patch would sometimes
4798 cause fsck to ignore a parameter on fsck's command line in some rare
4801 Make sure e2fsprogs doesn't write garbage into the reserved portion of
4804 Make sure resize2fs releases the blocks belonging to the old inode
4805 table blocks when moving the inode table. (Addresses Debian Bug:
4808 Skip the r_resize_inode test if resize2fs is not compiled (due to
4809 configure --disable-resizer)
4811 E2fsck now checks the summary filesystem accounting information, and
4812 if any of the information is obviously wrong, it will force a full
4813 filesystem check. (Addresses Debian Bug #291571)
4815 Fix e2fsck to not complain when the resize_inode feature is enabled,
4816 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
4819 Fix e2fsck to note delete symlinks that contain an extended attribute
4820 after the ext_attr feature flag has been cleared. (Addresses Red Hat
4823 Add new utility program, copy_sparse.c, which is very useful
4824 for dealing with large sparse files (such as e2image files).
4826 Add support for jnl_blocks[] for debugfs's set_super_value.
4828 Fix filefrag so that it works correctly with sparse files.
4830 Filefrag -v will print first and last blocks.
4832 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
4835 Add mke2fs support so that it can support filesystems larger than 4TB
4836 automatically, by retrying with a 4k blocksize if the device size is
4837 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
4840 Change blkid to test for NTFS first because Windows sometimes doesn't
4841 clear enough of the parition to confuse the probing routines into
4842 thinking the old filesystem type is still valid. (Addresses Debian
4845 Add support for swap partition label and uuid's in the blkid library.
4847 Add support to the blkid library to recognize Oracle ASM volumes.
4849 Make blkid -t display all devices that match the specified criteria,
4850 not just the first one, and work more consistently when the blkid
4851 cache file is not available or set to /dev/null. (Addresses Debian
4852 Bug #290530 and #292425)
4854 Badblocks will now correctly display block numbers greater than
4855 999,999,999 in its progress display.
4857 The tune2fs program will not allow the user from setting a ridiculous
4858 number of reserved blocks which would cause e2fsck to assume the
4859 superblock was corrupt. E2fsck's standards for what is a ridiculous
4860 number of reserved block has also been relaxed to 50% of the blocks in
4863 The blkid library will return vfat in preference to msdos, and ext3 in
4864 preference to ext2 (if the journalling flag is set) so that mount will
4865 do the right thing. (Addresses Debian bug #287455)
4867 Mke2fs will now use the -E option for extended options; the old -R
4868 (raid options) option is still accepted for backwards compatibility.
4869 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
4871 Mke2fs will now accept a size in megabytes, gigabytes, and other units
4872 (via "32m" or "4g" on the command line) if the user finds this more
4873 convenient than specifying a block count.
4875 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
4876 cache conherency problem.
4878 Debugfs now supports a new command, set_inode_field, which allows a
4879 user to manually set a specific inode field more conveniently, as well
4880 as set entries in the indirect block map.
4882 Debugfs's set_super_value command has been enhanced so that the user
4883 can set most superblock fields, including the date/time fields and
4884 some of the more newsly added superblock fields.
4886 E2fsprogs programs now accept an offset to be passed to the file
4887 specifiers, via the syntax: "/tmp/test.img?offset=1024".
4889 E2fsprogs programs will now accept blocksizes up to 65536; kernel
4890 support on the x86 doesn't exist for now, but it can be useful on
4891 other architectures with page sizes greater than 4k. There are 2.6
4892 kernel patches out there which enable this, but they are of this
4893 writing still experimental.
4895 The e2image command now takes the -s option which will scramble
4896 directory entries for raw image files.
4898 Fix a file descriptor leak in the filefrag program.
4900 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
4903 Fix bug in debugfs where kill_file would lead to errors when deleting
4904 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
4906 Fix bug in the blkid library when detecting the ocfs1 filesystem
4908 Remove obsolete EVMS 1.x and a.out DLL support.
4910 E2fsck will attempt to recover from a journal containing illegal blocks.
4912 Fixed two potential ordering constraint problems in e2fsck which might
4913 cause the filesystem to be corrupted if e2fsck is interrupted during a
4914 (extremely narrow) race window. Thanks to Junfeng Yang from the
4915 Stanford Metacompilation group for pointing this out.
4917 Fixed bug in e2fsck where it would not accurately detect whether or
4918 not the system is running on adaptor if the ACPI device representing
4919 the AC adapter didn't correspond to the what was used on IBM
4922 Change e2fsck to accept directories greater than 32MB.
4924 Fix e2fsck so that a checkinterval of zero disables a time-based check
4927 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4928 to the PAGER environment variable. (Addresses Debian Bug #239547)
4930 Tune2fs will not mark rewrite the superblock if the feature bitmasks
4933 The debugfs program will set the filetype information when creating a
4936 Add debugfs -d option to use a separate source of data blocks when
4937 reading from an e2image file.
4939 Add e2image -I option which allows the e2image metadata to be
4940 installed into a filesystem.
4942 Fixed bug in the badblocks program which caused "done" to always
4943 appear in english even when a translation was available. (Addresses
4946 The blkid program has a new option -o which controls the output format
4947 of the blkid program; this is makes blkid more convenient to use in
4950 Fix a minor bug in uuid library, which was not using the full 14 bits
4951 of clock sequence when generating UUID's.
4953 Fix a Y8.8888K problem in the uuid library.
4955 Logsave now creates a new session id for itself to avoid getting
4956 killed by init whan transitioning between init levels.
4958 Change the licensing of the UUID library to be the 3-clause BSD-style
4959 license; this allows Apple to use the uuid library in Darwin.
4961 Add ocfs and ocfs2 probe support into the blkid library.
4963 Fix a memory and file descriptor leak in the blkid library.
4965 The blkid library will revalidate the device if the system time is
4966 earlier than last verification time of the device, since that
4967 indicates that the system time is probably nottrustworthy.
4969 The blkid library will override the default location of the blkid.tab
4970 file by the BLKID_FILE environment variable, if it is available.
4972 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4974 Add various portability fixes for lame new versions of glibc, Darwin
4975 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
4976 Bugs #239934, #264630, #269044, #255589, #289133)
4978 Add support for Windows 9x/NT under Cygwin.
4980 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
4981 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
4983 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
4985 Update the rpm spec files so that it works better with Fedora core 2
4988 Fixed various Debian packaging issues (see debian/changelog). In
4989 particular, fixed the Debian initrd scripts. (#241183, #248050,
4996 Fixed various gcc -Wall warnings.
4998 The uuid library now has new functions uuid_unparse_upper() and
4999 uuid_unparse_lower() which forces the case of the hex digits to be
5000 upper case, or lower case.
5002 The build process has been speeded up by enhancing the subst program
5003 to update the modtime on the generated files even when the generated
5004 file hasn't changed.
5006 The uuid library now uses C99 stdint.h types instead of custom types.
5008 Updated config.guess and config.sub with newer versions from the FSF.
5010 Removed out of date .cvsignore files from the source distribution.
5012 The ext2fs_unlink() function will return an error if both the name and
5013 inode number are unspecified, to avoid doing something surprising
5014 (such as unconditionally deleting the first directory entry).
5015 Directory entries are now deleted by coalescing them with the previous
5016 directory entry if possible, to avoid directory fragmentation. This
5017 is not an issue with the e2fsprogs suite, but may be a problem for
5018 some of the users of libext2fs, such as e2tools.
5020 Add support for version numbers of the form "1.36-rc1".
5022 Fix build of mke2fs.static.
5024 Add basic ext2fs library support for large (EA in inode) inodes.
5026 The test_io mechanism can now abort after n reads or writes to a
5027 particular block. The block is specified by TEST_IO_BLOCK environment
5028 variable, and the read/write count by the TEST_IO_READ_ABORT and
5029 TEST_IO_WRITE_ABORT environment variables. The block data is now only
5030 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
5032 UUID_DEFINE() in the uuid library now creates a static variable, with
5033 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
5034 be used in header files.
5036 Add support for the install-strip and install-shlibs-strip targets, as
5037 suggested by the GNU coding guielines. "make install" no longer
5038 strips the binaries which are installed.
5040 Remove support for the --enable-old-bitops configure option which was
5041 only for very old sparc systems.
5043 Remove support for --enable-clear-htree; this was only needed during
5044 the early development of the htree patch.
5046 Use Linux-kernel-style makefile output so it is easier to see compiler
5049 Update gettext files to version 0.14.1.
5051 Update to use autoconf 2.5x.
5053 Improved support for compiling e2fsprogs under dietlibc.
5055 Make e2fsprogs portable to Solaris and FreeBSD systems.
5057 Add blkid_verify(), blkid_get_library_version(), and
5058 blkid_parse_version_string() functions to the blkid library.
5060 Add pkg-config files for e2fsprogs's libraries.
5062 Fix "make uninstall" to so that it removes everything that is installed.
5064 Add a configure --enable-maintainer-mode option which enables the
5065 makefile rules to rebuild the configure script from configure.in, and
5066 to reubuild the .gmo files in po directory.
5068 Drop the sparc assembly bitwise operations; it's less efficient
5069 than the GCC 3.4 compile code and triggers compiler warnings on
5070 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

5074 E2fsprogs 1.35 (February 28, 2004)
5075 ==================================
5077 E2fsck has a new -k option, which in conjunction with the -c options,
5078 preserves the existing badblocks list.
5080 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
5082 E2fsprogs will now deal correctly with symlinks that contain
5083 extended attribute information, which can be created using SE Linux.
5084 (Addresses Debian Bug #232328)
5086 Remove a double longjump into an invalid stack frame bug in e2fsck.
5087 (This was during an abort sequence, which normally worked on Linux and
5088 caused a core dump on other operating systems.)
5090 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5091 (the NLS library will replace "" with the .po header information).
5093 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
5094 dump due to a division by zero error. (Addresses Debian bug #207082)
5096 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
5097 when reconnecting a directory requires creating a lost+found
5098 directory. (Addresses Debian bug #219640).
5100 Fixed a bug where e2fsck would bomb out if a journal needed to be
5101 replayed when using an alternate superblock.
5103 E2fsck will give an extra grace period before actually forcing a check
5104 if the laptop is running on battery. The next time fsck runs while
5105 the system is on the AC mains, or after the grace period is exceeded,
5106 the filesystem will be checked. (Addresses Debian bug #205177)
5108 E2fsck will inform the user when there are 5 or fewer mounts before a
5109 filesystem check will be forced. (Addresses Debian bug #157194)
5111 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
5112 We now correctly handle the case where there is an overlap between a
5113 block group descriptor or a superblock and a bad block indirect block.
5114 In the case where the indirect block is corrupted, we now suggest
5117 Fix byte swap bugs in e2fsck that caused the journal backup location
5118 in the superblock and symlinks created by SE Linux to be cleared
5119 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
5121 E2fsck -c now replaces the current list of bad blocks with the ones
5124 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
5125 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
5127 Fix a potential bug in e2fsck which could cause it to core dump when
5128 trying to print the location of the backup superblock.
5130 Protect against a potential core dump in e2fsck when printing a
5131 message about backup superblocks.
5133 Add support for backing up the journal inode location in the
5134 superblock. E2fsck will automatically save the journal information in
5135 the superblock if it is not there already, and will use it if the
5136 journal inode appears to be corrupted. ext2fs_add_journal_inode()
5137 will also save the backup information, so that new filesystems created
5138 by mke2fs and filesystems that have journals added via tune2fs will
5139 also have journal location written to the superblock as well.
5140 Debugfs's logdump command has been enhanced so that it can use the
5141 journal information in the superblock.
5143 E2fsck will now update all superblocks when moving the journal inode.
5145 Shrink the size of the e2fsck executable by moving some initialized
5146 variables to the BSS segment.
5148 E2fsck will avoid printing the ^A and ^B characters which bracket the
5149 progress bar when stdout and stdin are a tty device instead of a pipe
5150 to another program. (Addresses Debian bug #204137)
5152 Debugfs's mkdir command will automatically expand the directory if
5153 necessary. (Addresses Debian Bug: #217892)
5155 Fixed a bug in debugfs so that copying a file from /dev/null uses the
5156 correct mode bits. (Addresses Debian Bug: #217456)
5158 If the environment variables DEBUFS_PAGER and PAGER are not set,
5159 debugfs now searches for the appropriate pager to use, beginning with
5160 /usr/bin/pager, and then falling back to 'more' and 'less'.
5161 (Addresses Debian bug #221977)
5163 Debugfs will now support 2.6 device numbers where the major or minor
5164 number may be larger than 255. (Addresses Sourceforge bug #865289)
5166 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
5168 Chattr now stops processing options when it sees '--'. (Addresses
5171 Fix regression tests so they work correctly when e2fsprogs is compiled
5172 with configure --disable-htree.
5174 Fix bug in uuid library when there is no network card and the library
5175 is generating a time-based uuid. The random MAC address was not
5176 correctly generated to be a multicast address.
5178 Add compile_et extensions from Heimdall that were missed the first time
5181 Fix bug in badblocks when using O_DIRECT; we need to make sure that
5182 we're reading from an offset which is page aligned. For read-only and
5183 read-write tests, we try to recover after an error so that we can
5184 continue reading on page-aligned boundaries. (Addresses Debian Bug

5193 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
5195 Fixed various Debian packaging issues (see debian/changelog).
5200 Fixed a build problem so that e2fsprogs would compile with the
5201 --enable-profile option to configure selected. (Addresses Sourceforge
5204 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
5205 Bugzilla Bug #112448)
5207 Centralize code which calculates the location of the superblock
5208 and block group descriptors so that it is in a single library routine.
5210 Added two new functions, ext2fs_file_open2() and
5211 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
5213 Fix compile_et to output the correct prototype for
5214 initialize_xxx_err_table_r() in the header file. (Addresses Debian
5217 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
5219 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
5220 present. This is for when we try stuffing an int into void * pointer.
5222 Fix type-punning which can cause gcc 3.x to miscompile code by getting
5223 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
5224 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
5225 **'. The EVMS code uses an ugly union approach since we don't want to
5226 modify the EVMS interfaces.
5228 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
5229 aid build process on systems can use invoke GNU make as "gmake".
5231 Added regression testing for mke2fs.
5233 Fixed gcc -Wall nitpicks.
5235 Fixed various compiler warnings.
5237 Add portability fixes for FreeBSD and for using fsctl under Darwin to
5238 support ext2 ioctl's.
5241 E2fsprogs 1.34 (July 25, 2003)
5242 ===============================
5244 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
5245 a tight loop while waiting for a child fsck to exit in some cases.
5246 This burns CPU times which slows down the low-level filesystem check.
5248 Added code to mke2fs to assure that the default block size for a
5249 filesystem is at least as big as the sector size of the device, if it
5252 Changed mke2fs and resize2fs to round the default size of a filesystem
5253 to be an even multiple of the VM pagesize in order to avoid a Linux
5254 kernel bug introduced when the storage of the buffer cache was moved
5255 into the page cache.
5257 Mke2fs will warn the user when creating a filesystem with journaling
5258 and a blocksize greater than 4096. (Addresses Debian bug #193773)
5260 Fixed a bug in resize2fs which caused it to fail on filesystems with a
5261 non-empty bad block list. Resize2fs now discards any blocks on the
5262 badblock list which are no longer part of the filesystem as the result
5263 of a filesystem shrink. (Note: this means that shrinking and then
5264 enlarging a filesystem is no longer a reversible operation;
5265 information about bad blocks in the part of the filesystem which is to
5266 be chopped off will be lost.)
5268 Changed resize2fs so the user can use prefixes to specify the units of
5269 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
5270 and to make the error and informational messages explicitly display
5271 the blocksize used by the filesystem, in order to avoid confusion.
5272 (Addresses Debian bug: #189814)
5274 Added a new debugfs command, dump_unused, which dumps the contents of
5275 all unused blocks to stdout. (Useful as an emergency try-to-find
5276 deleted data command.)
5278 Added a new debugfs command, imap, which prints the location of a
5279 specified inode in the inode table.
5281 Fixed a bug in the badblocks program which caused it to use one bit of
5282 randomness in its non-destructive read/write test, instead of using a
5283 full 8 bits of randomness.
5285 Added a new option (-t) to badblocks, which allows the user to control
5286 the test pattern(s) used when checking a disk.
5288 The blkid probe function now more correctly detects UDF filesystems.
5290 Fixed a bug in the blkid library which caused it to not update its
5291 cache if a filesystem changes from having a label to not having a
5294 Fixed a bug in the blkid library wihch could avoid an infinite loop
5295 in blkid_find_dev_with_tag() if /proc is not mounted and there the
5296 /etc/blkid.tab file has not yet been created.
5298 Fixed the badblocks program so that the destructive read/write test
5299 honors the -c option, and to use O_DIRECT when possible to avoid
5300 thrashing the system block buffer cache.
5302 Fixed various NLS issues.
5303 - Added Czech and Swedish translations
5304 - Removed testing NYC translation
5305 - Fixed NLS support for message abbrevations in e2fsck
5306 - Remove de-utf.po, since we shouldn't have two versions using different
5308 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
5309 simplify the statistics reporting in e2fsck.
5311 Changed configure.in so that its defaults for *BSD systems no longer
5312 build an fsck wrapper, and not to install in /usr/local by default.
5314 Fixed some minor spelling errors/typo's in e2fsck and the configure
5317 Fixed various Debian packaging issues (see debian/changelog).
5319 Updated and clarified man pages. (Addresses Debian Bug #195616)
5324 Fix gcc -Wall nitpicks.
5326 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
5327 NLS support by default. (Added partial workaround for gettext/Darwin
5328 incompatibility problems.)
5330 Added full MIT KRB5 and Himdall compaibility support to the com_err
5331 library and the compile_et program. (Addresses Debian bug #191900)
5333 Added the blkid_known_fstype() function to the blkid library, which
5334 returns true if it is passed a filesystem type which is recognized by
5335 the blkid probing functions.
5337 Improved the documentation for the blkid library.
5339 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
5340 returns the hardware sector size of a device, if it is available.
5342 Added a dependency in the blkid library's .so file to the uuid
5343 library, since the former uses the latter. (Addresses Debian bug
5346 Added --with-diet-libc and --disable-evms to the configure script.
5348 Fixed a minor memory leak in the badblocks program.
5350 Fixed a portability problem in tune2fs --- not all systems have strptime().
5352 Fixed a portability problem in debugfs with the use of getopt() more
5353 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
5356 Add support Windows support to ext2fs_get_device_size().
5358 Added (normally disabled) debugging code to the Unix I/O manager which
5359 causes it to disable all userspace caching if the NO_IO_CACHE is
5362 Changed the test I/O manager so it can always be linked into e2fsck,
5363 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
5364 configure script. The test I/O manager will only print any debugging
5365 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
5366 variables are set, which specifies which I/O operations are logged and
5367 a block number to watch, respectively. The log messages are sent to
5368 stderr by default, unless a filename is specified via the
5369 TEST_IO_LOGFILE environment variable.
5372 E2fsprogs 1.33 (April 21, 2003)
5373 ===============================
5375 Added a new utility program, logsave, which captures the output of a
5376 command in a log file, even if the containing directory hasn't been
5377 mounted yet (in which case the it saves the output in memory until it
5378 can write out the logfile). This is useful for capturing the
5379 output of fsck during the boot sequence.
5381 Fixed some portability problems that were causing problems under
5382 the Cygwin32 environment.
5384 Mke2fs now interprets a negative number to the -b option as a minimum
5387 Fixed a bug in mke2fs which was incorrectly checking the argument to
5388 the -g option if the default block size was used. (Addresses Debian
5391 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
5392 it can not find filesystem checkers for jfs, reseirfs, and xfs.
5394 E2fsck now updates the global free block and inode counters from the
5395 block group specific counters quietly. This is needed for an
5396 experimental patch which eliminates locking the entire filesystem when
5397 allocating blocks or inodes; if the filesystem is not unmounted
5398 cleanly, the global counts may not be accurate.
5400 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
5401 2.0 is not yet supported; this only pulled in the bug fixes: fixed
5402 possible hangs caused by bugs in calling waitpid, and not setting the
5403 pipe to non-blocking mode; also fixed a file descriptor leak; made
5404 sure all functions call log entry/exit functions.)
5406 Badblocks now flushes its output file as bad blocks are discovered.
5408 The uuid library is now more paranoid about assuming the correctness
5409 of the /dev/random device; it mixes in a stream of bytes from
5410 random/srandom, just in case.
5412 Update Debian files to reflect the fact that I am now the Debian
5413 maintainer of e2fsprogs. Other various Debian-specific packaging
5416 Move the source tarball generation functions from the top-level
5417 makefile to the util/gen-tarball script.
5419 Updated the Turkish .po translation file.
5421 Added Heimdal and MIT krb5 extensions to the com_err library to make
5422 it more compatible with com_err libraries from those distributions.
5424 Changed dumpe2fs to always display the superblock fields relating to
5425 the journalling and/or directory indexing feature even if those
5426 features are not enabled.
5428 Updated and clarify copyright statement vis-a-vis alpha releases of
5431 The ss library will now try to dynamically link to the readline
5432 library and use it if it is present in the system. This means that
5433 the debugfs program now has line editing and history features. The
5434 SS_READLINE_PATH environment variable is used to find a readline or
5435 readline-compatible library.
5437 E2fsck now finds most duplicate filenames (all when rebuilding all
5438 directories via the -D option) and offers to delete or rename
5439 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
5441 Fix bug in e2image. When writing out a raw image file, include data
5442 blocks from symlinks that do not store the symlink within the inode.
5444 Fix bug in resize2fs which incorrectly moved the block and inode
5445 bitmaps for sparse superblock filesystems and incorrectly marked
5446 blocks as in use. (Addresses Debian bug #174766)
5448 Added a new shared library, the blkid library, which efficiently
5449 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
5450 and UUID filesystem specifiers without needing to search all of the
5451 devices in the system. Instead, the device is looked up in a cache
5452 file, and then verified to make sure the blkid cache is correct.
5454 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
5455 the device name, using the blkid library. (Addresses Debian bugs
5458 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
5459 used for spaces in device labels.
5461 Removed 32-bit limitations for debugfs's dump command.
5463 If the user specifies a large number of inodes, Mke2fs will
5464 automatically adjust the number of blocks per group to find a valid
5465 set of filesystem parameters.
5467 Add workaround to detect broken MD devices where when some of the
5468 underlying devices are marked read-only, writes to the MD device are
5469 silently dropped. E2fsck will detect if there is an attempt to run
5470 the journal twice, and abort with an error if this is the case.
5471 (Addresses IBM Bugzilla bug #1226)
5473 E2fsck will print an error if more than one of the -p/-a, -n or -y
5474 options are specified.
5476 E2fsck will fix HTREE corruptions in preen mode, without stopping the
5477 boot process. This is needed because the 2.4 ext2 filesystem
5478 accidentally had the INDEX_FL backwards compatibility code removed.
5480 Mke2fs no longer creates filesystems with the dir_index flag set by
5481 default; the user has to specifically request it.
5483 Update and clarified various man pages. (Addresses Debian bugs
5484 #173612, #175233, #175113, and #170497, #185945, #188318)
5486 Created man page for the mk_cmds program (from the libss library).
5491 Fix various gcc -Wall nits.
5493 Fixed a lot of portability problems that caused e2fsprogs not to build
5494 successfully under Solaris and Apple/Darwin.
5496 Fixed a Makefile dependency to allow building e2fsprogs using parallel
5499 Changes to create a subset distribution which consists only of the
5500 et, ss, uuid, and blkid libraries. The configure script and top-level
5501 makefile were changed to support working with a subset distribution.
5503 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
5504 actually used, and might people who are looking for
5505 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
5507 Updated debian files to fix a number of Lintian warnings.
5509 Updated config.guess and config.sub with newer versions from the FSF.
5511 Removed unnecessary libraries from being linked into the fsck, lsattr,
5512 chattr, and blkid executables.
5514 E2fsprogs 1.32 (Nomvember 9, 2002)
5515 ==================================
5517 Fixed a bug in the Unix I/O routines which caused needless writebacks
5518 of clean blocks from the unix_io cache (they were erroneously marked
5519 as being dirty, so they were getting written back to disk before
5520 getting evicted from the disk cache). This was harmless, but it
5521 significantly slowed down e2fsck.
5523 Made some other minor optimizations to the Unix I/O routines to save a
5524 small amount of CPU time.
5526 Updated internationalization files.
5529 E2fsprogs 1.31 (Nomvember 8, 2002)
5530 ==================================
5532 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
5533 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
5534 handling for child process that die unexpectly. Add a hack to force
5535 mkfs to create filesystems that won't cause problems with hardware
5536 that has 2k or 4k minimum blocksize requirements. Read from child
5537 processes in non-blocking mode, so that the GUI continues to update.
5539 Fix e2fsck so that it returns the appropriate exit code when the root
5540 filesystem has been changed, so that system's rc scripts will be told that
5541 the system needs to be rebooted.
5543 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
5544 was set, some of the descriptor blocks that should have been written
5545 out were getting skipped.
5547 Changed e2fsck to force out changes to the backup copies of the
5548 superblock and block group descriptors when important changes are made
5549 to those data structures.
5551 Fix a bug where e2fsck could erroneously mark a filesystem as being
5552 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
5553 introduced in e2fsprogs 1.28.)
5555 If journal debuging is enabled using --enable-jbd-debug, the debugging
5556 level is now set via the E2FSCK_JBD_DEBUG environment variable.
5558 If byteswapping support is disabled using configure --disable-swapfs,
5559 skip the tests which depend on byte-swapping, so that "make check"
5562 Lshattr will now display the indexed directory flag. Also, some of
5563 the more esoteric compression flags are supressed unless compression
5564 support has been enabled.
5569 E2fsprogs 1.30 (October 31, 2002)
5570 =================================
5572 When resizing a filesystem, and inodes need to moved, resize2fs will
5573 update the inode's ctime field, and the mtime field of the containing
5574 directories, so that incremental backups using dump/restore will work
5577 In order to avoid spurious errors, e2fsck wil check the last
5578 superblock write time to determine whether or not it can safely use
5579 the LOW_DTIME checks to determine if there are inodes on the orphan
5580 inode linked list that had somehow gotten disconnected. (Addresses
5581 Sourceforge bug #620980)
5583 Partition in /proc/partitions that being with the string "lvm" are
5584 considered real partitions even if they do not end with a number.
5586 Fixed a bug in the the uuid generation function, where if /dev/urandom
5587 is not present, but /dev/random is, and there isn't sufficient
5588 entropy, the get_random_byte function could spin a loop forever.
5590 E2fsck, mke2fs, etc. will now reliably notice when image files are
5591 mounted using the loopback interface. (Addresses Sourceforge bug
5594 When flushing buffers (as is done by badblocks, for example) check to
5595 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
5596 FDFLUSH ioctl which causes the MD device driver which causes confusing
5597 syslog messages about obselete ioctl messages. (Addresses Sourceforge
5600 Debugfs's write command now checks to see if the destination filename
5601 exists before creating it. (Addresses Sourceforge bug #478195.)
5603 When installing man pages, search for compressed man pages using all
5604 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
5606 Fixed a bug in fsck where multiple filesystems specified on the
5607 command were not being checked in parallel due to a logic bug
5608 introduced to support the FSCK_MAX_INST environment variable.
5610 We have added a new superblock field, s_mkfs_time, which indicates
5611 when a filesystem was created. It is set via mke2fs, and printed out
5612 by dumpe2fs, but is not actually touched by the kernel.
5614 Dumpe2fs has been made more robust by not aborting if there is an
5615 error reading the block/inode bitmaps; instead it will still print out
5616 the location of the block/inode bitmaps and inode table.
5618 Add support for the an alternative block group descriptor layout which
5619 allows for on-line resizing without needing to prepare the filesystem
5620 in advance. (This is the incomat feature flag meta_bg.)
5622 Add support for storing default mount options in the superblock, so
5623 that the filesystem can be mounted with specific mount options without
5624 needing to specify them on the mount command line or in the /etc/fstab
5627 Add support for a new inode flag, which is to be used for indicating
5628 the top of directory hierarchies for the Orlov block allocator.
5630 Fix e2fsck so that if it creates the lost+found directory, it does so
5631 with the more apporpriate permissions of 0700. Also change
5632 mklost+found so that it also creates the directory 0700.
5634 Fixed format bug in e2fsck if NLS is in use.
5636 Add a German translation for e2fsprogs's NLS support.
5638 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
5639 the beginning of the inode table. This won't matter much, since if
5640 there is a bad block at the beginning of the inode table, the root
5641 directory won't be available. But at least e2fsck won't crash in this
5644 Fixed endian problems in the htree code for e2fsck and debugfs.
5646 When byte-swapping a filesystem on a PPC architecture, byte-swap the
5647 bitmaps since the historical big-endian ext2 variant had byte-swapped
5648 bitmaps, and the ext2fs library assumes this. This fixes the
5649 regression test suite on PPC machines.
5651 Fix e2image so that it handles a bad block in the inode table
5654 E2fsck now uses a more sophisticated algorithm to salvage corrupted
5655 directories that recovers more information in the corrupted directory
5658 E2fsck now performs additional consistency checks on indexed (HTREE)
5661 Fix bug where efsck might get confused about whether a completely
5662 empty directory block is an empty leaf block or an interior htree
5663 node. This could cause e2fsck to get confused into think that a valid
5664 indexed directory was corrupted.
5666 E2fsck no longer creates an empty directory entry at the end of a
5667 directory block when optimizing a directory. This would cause some
5668 earlier versions of the dxdir kernel code to corrupt the directory
5669 when attempting to split a node containing an empty directory entry.
5671 E2fsck could sometimes in rare circumstances leave the indexed flag
5672 set after a small directory was optimized by compressing it instead of
5673 indexing it. (This should never happen in real life, since
5674 directories that small wouldn't have been indexed, but better safe
5677 E2fsck now only updates the master superblock in all cases. This
5678 slightly shortens its run time.
5680 Ext2ed can deal with directory entries of length 0; previously it
5681 would get stuck in an infinite loop.
5683 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
5684 specifiers. (Sourceforge patch #613447)
5686 Badblocks will now work correctly on read-only devices such as
5687 CD-ROM's. (Sourceforge patch #600451)
5689 Updated and clarified man pages. (Addresses Debian bug #167108)
5692 E2fsprogs 1.29 (September 24, 2002)
5693 ===================================
5695 Fixed a bug in e2fsck which could corrupt a directory when optimizing
5696 it (via the -D option) or rebuiliding the hash tree index with a 1 in
5697 512 probability, due to a fence post error.
5699 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
5702 Mke2fs now enables the directory indexing flag by default. (Since
5703 this is a compatible feature flag, it's safe to do so.)
5705 Tune2fs will support setting the directory indexing feature flag. It
5706 will automatically set up the default hash algorithm and hash seed
5707 fields in the superblock.
5709 If the bone-headed user enters the root filesystem twice in
5710 /etc/fstab, the -R option which skips the root filesystem will skip
5711 all of them. (Addresses Debian bug #159423). Note! This is not a
5712 precedent for dealing intelligently with any other kind of doubled
5713 entry in /etc/fstab!
5719 Removed perror declaration in lib/et/internal.h. All modern systems
5720 can be expected to define perror() these days. Besides, the lib/et
5721 code wasn't using perror at all anyway. :-)
5724 E2fsprogs 1.28 (August 31, 2002)
5725 ================================
5727 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
5728 for setting the htree flag is not included yet, although it can be
5729 manually turned on via the debugfs program.
5731 Clarified e2fsck error message which is printed when it cannot find
5732 sufficient contiguous block when relcating filesystem metadata.
5734 Added support for building an EVMS plugin module for ext2/3. This
5735 module is substantially the same as the EVMS module shipping with EVMS
5736 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
5737 for use with EVMS 1.0 (which did not include the ext2 plugin module),
5738 if the configure --enable-old-evms flag is given.
5740 Fsck will search through EVMS volumes when trying to resolve
5741 filesystem specifications such as LABEL=xxx or UUID=xxx.
5743 Added a new utility program, /sbin/findfs, which will return
5744 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
5747 Update and clarified various man pages. (addresses Debian Bug #145044,
5748 #146437, #131350, #151990, #144621, #141938)
5750 If there are no filesystems specified on fsck's command line, fsck now
5751 treat that as if the -As options were given. Previously it would
5752 simply do nothing. (Addresses Debian Bug #153102)
5754 Mke2fs no longer treats a failure to be able to clear the MD signature
5755 at the end of the filesystem as a fatal error. (Addresses Debian Bug
5758 The e2p library functions (which are used by lsattr and chattr) now
5759 double check to make sure the file is a regular file or directory
5760 before attempting to use the ext2 ioctls. Some device drivers
5761 unfortunately respond to the ext2 ioctl's with unknown behaviour.
5762 (Addresses Debian Bug #152029).
5764 The extended attribute handling has been updated to correspond with
5765 the latest V2 bestbits ACL code.
5767 Fixed bug in e2fsck which caused it to not clear the dtime field when
5768 processing truncated inodes on the orphan list. This could cause data
5769 loss(!) if a filesystem is rebooted before a truncate has been
5772 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
5773 algorithms. This makes e2fsck much faster in the case of severely
5774 corrupted filesystems where a large number of blocks are claimed by a
5775 large number of inodes. (Thanks to the 2.5 IDE device driver for
5776 inspiring this work.)
5778 Resize2fs has been significantly sped up when shrinking and expanding
5779 a filesystem by a very small number of blocks (for example, when EVMS
5780 is converting a partition to be an EVMS legacy volume).
5782 Added a new option to e2fsck, -D, which will optimize or compress all
5783 of the directories in the filesystem.
5785 E2fsck now catches SIGINT and SIGTERM to make sure it will can
5786 properly clean up and only exit at safe points. Fsck will pass
5787 SIGINT/SIGTERM to its child processes, and wait until they have all
5788 exited before it exits.
5790 The uuid parsing code in the uuid library now properly complains when
5791 an illegally formated uuid is presented to it. (Addresses Debian bug
5794 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
5795 and 2.4.17, since the workaround can cause problems when using a 2.4
5796 kernel with an old version of glibc built with the 2.2 headers.
5798 Fixed a bug in mke2fs where it wasn't properly clearing the initial
5799 superblock used by other filesystems. (Addresses Debian bug #147256.)
5801 Added support for the synchronous directory feature written by Andrew
5804 The debugfs program can delete directories using the rmdir command.
5806 Add support for 8k and 16k filesystems (for systems with page sizes
5807 that are greater or equal to 8k or 16k, respectively). Note that
5808 these filesystems can not be mounted on x86 systems, or other systems
5809 with only 4k page sizes, due to limitations in the current Linux VM
5812 Resize2fs requires that the filesystem state be valid and have no
5813 errors; otherwise, e2fsck -f must be run first. (Previously it simply
5814 required that the last fsck time be greater than the last mount time.)
5816 Configure now defaults the man pages directory to /usr/share/man on
5819 E2fsck now offers to truncate inodes which contain too many blocks (so
5820 that i_blocks would overflow. Also fixed handling of large sparse
5823 E2fsck now more completely checks for symlink validity, including
5824 requiring NULL termination and length checks.
5826 E2fsck will offer to try forcing a disk write to remap a bad block
5827 after finding a read error when reading a filesystem metadata block.
5829 Fixed a bug in debugfs which caused the -b and -s options to crash
5830 debugfs, as well as breaking the testb, setb, and clearb functions.
5832 Added a bmap command to debugfs which calculates the logical to
5833 physical block mapping for a particular inode.
5835 Fixed a bug in code which checked to see if a device was mounted which
5836 sometimes (rarely) failed in the case of a plain file.
5838 Fixed a bug in resize2fs where when it reported an error, it would
5839 print a message erroneously indicating that the filesystem had been
5840 resized before it aborted.
5842 When resizing a plain file which is smaller than the requested size,
5843 resize2fs will attempt to extended the file so that programs like
5844 e2fsck will not complain that the file is too small.
5846 Resize2fs will print the actual new size of the filesystem when it is
5849 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
5850 information on big-endian systems.
5856 Fixed collisions with C++ reserved words.
5858 Added portability fixes for building e2fsprogs on the HURD and AIX.
5860 Added the ext2ed program for creation of test cases. (ext2ed has many
5861 limitations and bugs which make it unsuitable for production use.)
5863 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
5864 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
5865 name_len field is byte swampped on big-endian machines, since in the
5866 V2 structure, name_len is a char field which is doesn't need to be
5867 byte swapped --- except if an old-style kernel had byte-swapped the
5868 name_len field as part of the V1 structure.
5871 E2fsprogs 1.27 (March 8, 2002)
5872 ==============================
5874 The warning messages for mke2fs now go to standard error.
5876 Fixed to make sure "make check" runs all of the test programs with
5877 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
5879 The mke2fs program checks the boot sector for the BSD disk label, and
5880 avoids erasing it if it is there.
5882 Fixed a bug in e2fsck which caused it to core dump if the journal
5883 inode was missing when it was supposed to be there.
5885 E2fsck now prints ranges in pass 5 when printing deltas for the block
5888 Debugfs's "ls -l" command now will print out the file type information
5889 in the directory entry.
5891 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
5892 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
5894 Debugfs can now examine the experimental directory indexing
5897 Fixed bug in debugfs which caused it to core dump if modify_inode is
5898 called without an open filesystem.
5900 The debugfs lsdel command now runs its output through a pager first.
5902 When installing manual pages, remove the compressed manual pages first.
5904 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
5906 Fix the 2.4 resource limitation workaround introduced in 1.26 which
5907 actually broke things on mips32, sparc32, and Alpha platforms.
5909 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
5910 (which is required by the newer libintl libraries).
5915 Fixed various gcc -Wall complaints.
5917 Fixed a few memory leaks in the e2fsck journaling code, and in the
5918 ismounted code checking for a swap device.
5920 Add new inode I/O abstraction interface which exports an inode as
5923 Exported ext2_file_flush as a public interface.
5925 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5927 Lots of small random portability fixes to make e2fsprogs build under
5928 AIX --- even without the 5L compatibility toolkit, and even using the
5929 uber-crippled AIX native C compiler.
5932 E2fsprogs 1.26 (February 3, 2002)
5933 =================================
5935 Dumpe2fs will keep going now if the bad block inode can't be read.
5936 (Previously it stopped with a fatal error.)
5938 E2fsck will now give an opportunity to run the journal even if the
5939 recovery flag is not set. This is the default behaviour if e2fsck is
5940 using a backup superblock, since the needs_recovery flag will never be
5941 set in the backup superblock copies.
5943 E2fsck now automatically finds the backup superblock/group descriptors
5944 even when the primary superblock is completely destroyed for 2k and 4k
5945 filesystems. (Previously it just guessed/assumed that we were dealing
5946 with a 1k filesystem in that case, and users had to manually specify
5947 the backup superblock number.)
5949 Fixed a bug in e2fsck where it dereferences a null pointer when there
5950 is a problem opening a filesystem in preen mode.
5952 E2fsck now handles external journals correctly; previously it trashed
5953 the external journal device if the journal needed to be replayed.
5955 Work around ulimit incompatibility problem caused by recent 2.4
5956 kernels; the unix IO module will automatically try to set any resource
5957 limits to be infinite on startup.
5959 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5960 bitmap if it wasn't present and the blocksize was 2k or 4k.
5961 (Addresses Debian Bug #116975)
5963 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5964 clearing the new V2 fields if they do not make sense or if the ext3
5965 superblock is version 1 superblock.
5967 E2fsck will automatically relocate the ext3 journal from a visible
5968 file (i.e., /.journal) to an hidden inode if the filesystem has been
5969 opened read/write. This allows the users to add a journal while the
5970 filesystem is mounted, but the next time the system is rebooted, the
5971 journal file will disappear. This avoids problems with backups,
5972 stupid operators with superuser bits, etc.
5974 Fix a bug in fsck where it would not support a filesystem type of
5975 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5977 Fsck now supports fstab entries of the form "ext3,ext2". It will also
5978 automatically identify reiserfs filesystems.
5980 The number of processes spawned by fsck can now be limited using the
5981 FSCK_MAX_INST environment variable.
5983 Fsck now searchs the LVM proc hierarchy to find logical volumes which
5984 should be searched for UUID and label information.
5986 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5987 limit if at all possible, when opening a block device. (The filesize
5988 limit shouldn't be applied against writes to a block device.)
5990 In mke2fs and e2fsck, specifying the -c option twice will now do
5991 a read/write test on the disk. Update the man pages to encourage
5992 using the -c option, and to discouraging running badblocks separately,
5993 since users tend to forget to set the blocksize when running
5996 Mke2fs now automatically clears the immutable attribute on a
5997 pre-existing .journal file left over from a previous failed attempt to
5998 add a journal to an alreadyy-mounted filesystem.
6000 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
6003 Mke2fs now creates the lost+found directory with permissions of 0700,
6004 so that files that had previously lived in protected directory are
6005 safe if they get dropped in lost+found and the system administrator
6006 doesn't deal with immediately. (Addresses Debian #bug 118443)
6008 Mke2fs and e2fsck (and all programs that use the
6009 ext2fs_check_if_mounted function) will now properly identify that a
6010 device is mounted, even in cases where devfs has confused things with
6011 multiple devices names with the same identity, or if a dim-witted
6012 system administrator has done something stupid like creating device
6013 file aliases in their home directory. Also now checks for swap devices
6014 by using /proc/swaps. (Addresses Debian bug #106622)
6016 Added a new option (-T) to tune2fs which sets the time a filesystem
6019 Speed up e2image when creating sparse raw image files by optimizing
6020 away excess lseek() system calls.
6022 Fix support of large (> 2GB) files when used as a filesystem in
6023 mke2fs, tune2fs, debugfs, and findsuper.
6025 Debugfs's stat and icheck commands now properly deals with large (>
6028 Debugfs's set_super_value command now prints out the list of valid
6029 superblock fields which can be set using the command.
6031 Debugfs's rm and kill_file command now updates the superblock free block
6032 and inode counts, thus keeping the filesystem consistent.
6034 Debugfs's lsdel command now takes an optional argument which allows
6035 the user to only see the most recently deleted files.
6037 A new command (undel) was added to debugfs which automates
6038 undeleting a deleted inode and linking it back to a directory.
6040 Debugfs's ls command now takes a new option, -d, which lists
6041 deleted directory entries.
6043 Debugfs's testb, freeb, setb, and find_free_block commands now take an
6044 optional count argument.
6046 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
6047 be used to signal that a particular inode should not be eligible for
6048 tail-merging --- this is needed for programs like LILO.
6050 The findsuper (an unreleased, uninstalled utility program) has been
6051 improved to add extra validity checks and to add a progress meter.
6052 (It is still an unsupported program; the officially supported way to
6053 recover from a trashed partition table is to use gpart; findsuper is
6054 for wizards only. :-)
6056 Debugfs was fixed to compile with "configure --disable-swapfs".
6058 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
6060 Added new translation file for Turkish.
6065 Fix general gcc -Wall complaints.
6067 E2fsprogs (mostly) works with the dietlibc.
6069 The programming texinfo file has been expanded to include description
6070 of additional libext2fs functions. (Still not compeltely done, but a
6071 lot of the more important functions have been documented.)
6073 Added a umask structure to struct_ext2_filsys, which currently only
6074 modifies the behaviour of ext2fs_mkdir(), but if we add any file
6075 creation functions to libext2fs, we should also make sure they respect
6078 The build-rpm script was fixed to be a bit more safe.
6080 The tests' Makefile now has a way of automating test case creation
6081 for e2fsck, using "make testnew".
6083 Created a new function, ext2fs_dir_iterate2 which passes more
6084 information to the callback function (identical to the one used by
6085 ext2fs_dblist_dir_iterate). The directory iterator functions take a
6086 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
6087 directory entries. If the directory entry is deleted, the callback
6088 function will be called with the entry paraemter set to
6089 DIRENT_DELETED_FILE.
6091 Added new functions, ext2fs_inode_alloc_stats and
6092 ext2fs_block_alloc_stats, which takes updates block/inode allocation
6093 statistics in the bitmaps, block group descriptors, and superblock
6094 when inodes or blocks are allocated or deallocated.
6097 E2fsprogs 1.25 (September 20, 2001)
6098 ===================================
6100 This is primarily a bug-fix release; no new features were added, but
6101 there are a number of embarassing bug fixes and cleanups applied.
6103 Fix a bug mke2fs which causes stack garbage to be written to disk when
6104 zapping disk sectors. (This bug could cause mke2fs to core dump for
6105 some kernels, I suspect with security enhancement patches.)
6107 Remove unneeded #include of <linux/config.h> which was breaking
6108 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
6110 Updated tune2fs man page to reflect the fact that adding or removing a
6111 journal doesn't require running e2fsck.
6113 Remove use of AC_REQUIRE from autoconf which had been used to prevent
6114 AC_CANONICAL_HOST from being called twice; unfortunately this causes
6115 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
6116 used outside of autoconf macros. Fortunately, it doesn't seem to be
6117 necessary any more, anyway.
6119 E2fsck will now not fall back to an alternate superblock if the user
6120 specifies the superblock location explicitly on the command-line.
6121 This allows easier recovery from a situation where the primary
6122 superblock and block groups are slightly corrupted, but the backup
6123 superblocks are completely broken.
6125 Fix problem which caused compile_et and mk_cmds to blow up if
6126 e2fsprogs was in a directory with a pathname that contained spaces.
6128 We are now more paranoid about checking the entry in /etc/mtab to make
6129 sure the filesystem is really mounted, since some broken distributions
6130 (read: Slackware) don't initialize /etc/mtab before checking non-root
6131 filesystems. (Slackware also doesn't check the root filesystem
6132 separately, and reboot if the root filesystem had changes applied to
6133 it, which is dangerous and broken, but there's nothing I can do about
6136 Make UUID library C++ friendly by adding appropriate extern "C"
6137 declarations and using const in the function declarations.
6139 Fix up the com_err texinfo file so that it can product a valid info
6140 file (previously, it could only be used to generate paper
6141 documentation using texinfo.tex).
6144 E2fsprogs 1.24a (September 2, 2001)
6145 ===================================
6147 Fix brown-paper bug in mke2fs which caused it to segfault when
6148 printing the version string.
6151 E2fsprogs 1.24 (August 30, 2001)
6152 ================================
6154 Revert the BLKGETSIZE64 support, since for some distributions, this
6155 ioctl has been used by an unofficial kernel patch to update the last
6156 sector on the disk, and this was causing disk corruption problems as a
6159 Mke2fs is now more careful about zapping swap space signatures and
6160 other filesystem/raid superblock magic values so that programs like
6161 mount who try to use hueristics to determine the filesystem type of a
6162 partition are less likely to be confused.
6164 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
6165 regular file (since Andreas Dilger's on-line resizing tools will set
6168 Fixed some minor texinfo, man pages nits for spelling errors,
6169 texinfo warnings, etc. (Addresses Debian bug #110621.)
6171 E2fsprogs program no longer print the filesystem version number
6172 (i.e. 0.5b), since it only confuses people and doesn't serve any real
6175 E2fsck will once again compile under libc5, since it will supply its
6176 own version of strnlen if necesssary.
6178 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
6179 when specifying the external journal device. tune2fs will also search
6180 devices looking for the externla journal debice when removing.
6182 E2fsprogs 1.23 (August 15, 2001)
6183 ================================
6185 Add initial support for extended attributes (EA); e2fsck will
6186 correctly handle a filesystem with EA's and check the EA blocks for
6189 E2fsck's symlink sanity checking has been cleaned up. It now checks
6190 the i_size value of fast symlinks, and checks for immutable flags
6191 being set of symlinks, etc.
6193 E2fsck now offers to clear inodes which are special files that have a
6194 non-zero i_blocks or i_size field. (The i_size field check was in the
6195 previous version of the code, but due to a bug it didn't offer to
6196 clear the inode unless i_size and i_size_high were both non-zero.)
6198 E2image can now create "raw" image files, which only contain the
6199 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
6200 debugfs, etc., can be run directly on the raw image file.
6202 Add support for the 64-bit block device patches.
6204 Fixed bugs in creating external journals with a 1k blocksize.
6206 Add initial support for external journals (so long as the external
6207 journal only supports a single filesystem) in e2fsck.
6209 Remove requirement for needing to run fsck on a filesystem after
6210 removing a journal (either internal or external).
6212 The man pages now document how to create and manage external journals.
6214 Speed up the check of an ext3 filesystems by avoiding a needless flush
6215 of all of the superblock and block group descriptors.
6217 Speed up creating an internal journal using tune2fs in the case where
6218 the filesystem has a lot blocks already allocated.
6220 Tune2fs has been fixed to make sure that only error messages go to
6221 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
6223 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
6224 now not set the sparse_super feature. (Addresses Debian bug #108165)
6226 Add support in fsck for the filesystem type "auto".
6228 Fsck -A will not try to interpret device names for filesystems which
6229 have a pass number is 0. (Addresses Debian bug #106696).
6231 Fsck prints a warning message if now valid filesystems are passed to
6232 it. (Addresses Debian Bug #107458.)
6234 E2fsck now gives an explicit warning if there filesystem still has
6235 errors at the end of the run. (Addresses Debian bug #104502)
6237 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
6238 reflects an error. E2fsck will also not run the orphan list if the
6239 filesystem contains errors, since the orphan list might be corrupted.
6241 E2fsck now prints the number of large files when given the -v option.
6243 Fixed minor memory leaks in e2fsck.
6245 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
6248 E2fsprogs 1.22 (June 22, 2001)
6249 ==============================
6251 Fixed a bug in e2fsck's handling of orphan inodes which are special
6252 files (i.e., block/character device files, named FIFO's, etc.).
6254 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
6255 tune2fs to fail at adding a journal to a mounted filesystem.
6257 Fixed a few big-endian bugs in e2fsprogs
6258 * The directory block functions were accidentally reporting
6259 some directories as corrupted when they weren't.
6260 * If e2fsprogs is compiled --disable-swapfs, the C language
6261 equivalents weren't being included for big-endian platforms.
6262 (Fixes Debian bug #101686).
6264 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
6269 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
6270 ioctls, and allow them to be defined for non-i386 platforms.
6272 The uuid.h header file is now protected against multiple inclusions.
6274 E2fsprogs is now being developed using BitKeeper. Changed the test
6275 scripts to deal with BK's stripping CR characgters from text files,
6276 and changed the top-level Makefile.in to avoid including BitKeeper
6277 files when generating the source tarball.
6280 E2fsprogs 1.21 (June 15, 2001)
6281 ==============================
6283 Added new configure flags which allow a subset e2fsprogs to be built;
6284 this is most useful for boot floopies, since the resulting shared
6285 libraries and programs are slimmed down by removing features that
6286 aren't necessary for a boot floppy. The new flags that were added
6287 are: --disable-swapfs, which removes support for byte swapping old
6288 legacy PPC/68k filesystems, --disable-debugfs, which removes support
6289 for debugfs from the libext2fs library, --disable-imager, which
6290 removes support for the e2image program, and --disable-resizer, which
6291 removes support for resize2fs.
6293 E2fsck now prints the number of mounts or days elapsed since the last
6294 check when e2fsck is forced to check an otherwise clean filesystem.
6296 Tune2fs now prints an informative message about how often a filesystem
6297 will be checked when adding a journal to the filesystem, to remind the
6298 user that he/she may want to adjust those parameters using tune2fs
6301 Worked around hurd brain-damage which causes e2fsck to sometimes
6302 believe a filesystem is the root filesystem based on device numbers
6303 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
6306 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
6307 erroneous error with the -F option was specified.
6309 Fixed a ext3 recovery bug in the revoke handling; synchronized with
6312 Fixed two bugs in e2fsck's handling of dup block handling, dealing
6313 with relatively uncommon edge cases: a directory with an indirect
6314 block which is claimed by another file, and when the last inode in the
6315 filesystem has blocks claimed by another file.
6317 E2fsck now checks to see if the i_size field of a fast symlink is too
6318 big, and offers to clear the symlink if so.
6320 E2fsck now checks to see if i_size_high of special files is non-zero,
6321 and offers to clear i_size_high.
6323 Fix e2fsck's handling of incompatible journal flags so that the user
6324 has chance to abort, and then has the option to clear out the journal
6325 entirely. (Addresses Debian bug #98527.)
6327 Fixed a bug in fsck which could cause it to core dump if a mix of
6328 standard and non-standard device names are used in /etc/fstab.
6329 (Debian bug #100559)
6331 Fixed a bug in debugfs which caused read errors when copying a file to
6334 The debugfs set_super_value command can now modify the s_lastcheck field.
6336 Fixed a bug in lsattr and chattr which was accidentally introduced in
6337 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
6338 directories correctly because the change modified the layout of struct
6339 dirent to be incompatible with the libe2p shared library.
6341 Cleaned up the mke2fs manual page and included a discussion about why
6342 it's good to periodically check the filesystem even when journaling is
6348 Fix general gcc -Wall complaints.
6350 The types needed by the ext2 header files are now provided by
6351 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
6353 Integers are now preferred to longs when trying to find a 32-bit type
6354 in ext2_types.h. Also, if linux/types.h has already been defined,
6355 don't try to redefine the types.
6357 Fixed make depend script so that it automatically corrects the
6358 pathname cleanups performed by make -M, so I don't have to fix them up
6361 Fixed the d_loaddump test case to be more robust, and not depend on
6364 Removed debugfs's dependence on pread(), which was accidentally
6365 intrudced in e2fsprogs 1.20
6367 Fixed a performance bug in the libext2fs's icount routine; the size
6368 estimate of the icount array was incorrectly being calculated.
6370 Removed use of the badblocks compatibility functions in the e2fsprogs
6373 Added paranoia code which protects against strange cases where /etc
6374 isn't on the root filesystem, or if /etc/mtab doesn't exist.
6376 The header file ext2_types.h is now installed.
6378 Autoconf is used to determine when we are on big-endian machines,
6379 instead of doing run-time tests, to save a few bytes of code.
6381 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
6382 functions are no longer inline functions, which saves space and
6383 doesn't really cost any real performance.
6385 The ext2fs library no longer depends on the e2p library. (What need
6386 there was of it --- namely, fsetflags, was coded in-line).
6388 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
6389 when the user is stupid and tries compiling the package using "make
6392 Miscellaneous code cleanups:
6393 * Added missing files from Makefile.in's SRCS file, so that
6394 their dependencies would be properly calculated.
6395 * Removed redundant code
6396 * Fixed comments in code
6397 * Removed no-longer unneeded argsused #pragma.
6400 E2fsprogs 1.20 (May 20, 2001)
6401 =============================
6403 Add support for replaying the ext3 journal purely in user mode,
6404 including handling the orphaned inode list. Used code contributed by
6405 Andreas Dilger, with bug fixes and the orphaned inode handling done
6408 The mke2fs and tune2fs programs can create or modify a filesystem to
6409 include an ext3 journal. Tune2fs also can be used to remove an ext3
6410 journal from a filesystem.
6412 E2fsck will now check for the existence of a linked list of orphan
6413 inodes in the superblock, and clear those inodes before starting the
6414 rest of the filesystem check (but after the journal playback).
6416 E2fsck now validates the file descriptor passed to the -C option,
6417 which saves against the completion bar getting written to an
6418 unexpected location, such as the disk being checked. (Debian
6419 bug/wishlist #55220)
6421 E2fsck will now bump the filesystem revision number from zero to one
6422 if any of the compatibility bits are set.
6424 Fixed a bug where a badly corrupted directory on a big endian system
6425 could cause e2fsck to die with a bus error. The
6426 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
6427 the ext2 library now does alignment sanity checks on the rec_len field
6428 of the directory entry before using it.
6430 The ext2 library has been enhanced to make tune2fs safe to run on
6431 mounted filesystems. (Users could usually get away with using tune2fs
6432 on mounted filesystems before, but with the advent of ext3 and
6433 journaling, it became important to make tune2fs was *really* safe for
6434 use even when the filesystem being modified is mounted.) E2label is
6435 now implemented by tune2fs using an argv[0] dispatch, so that e2label
6436 is also now safe for use on mounted filesystems.
6438 Added a new program, e2image, which creates a backup of critical ext2
6439 filesystem data structures. The generated image file can be examined
6440 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
6441 the image file to help recover very badly damaged filesystems.
6443 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
6444 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
6445 large file when deciding whether or not the filesystem has large files.
6447 Fixed lsattr and chattr so that they work correctly on large files.
6448 (Fixes Debian bug #72690.)
6450 Removed limitation in get_device_size() which imposed a one terrabyte
6451 filesystem limitation. (Most 2.2 kernels still have a signed int
6452 problem which cause 1 TB block device limitation. Fortunately, the
6453 kernel patches to fix this are much easier than fixing the 2TB
6454 limitation in the kernel. :-)
6456 A max_mount_count of zero is now treated as if no mount count were
6457 set. (Previously, no mount count was indicated by using -1, and a
6458 mount count of zero caused e2fsck to always be run.)
6460 Mke2fs supports two new filesystem types largefile and largefile4.
6462 Mke2fs now adds some randomness in s_max_mount_count so that multiple
6463 filesystems won't be all checked at the same time under normal
6466 Fixed bug in the progress bar printing code which could cause e2fsck
6467 to core dump on an illegal filesystem.
6469 Fixed bug in fsck which could allow more than one instance of e2fsck
6470 to be printing a progress bar. (Debian bug #65267)
6472 Fsck using a UUID or a LABEL specifier will work even if devfs is
6473 compiled into the kernel and not mounted. If the pathnames in
6474 /proc/partitions are incorrect, fsck will search /dev for the correct
6475 device (using the new ext2fs_find_block_device library function).
6476 Fsck now also checks the RAID devices first so that they are properly
6477 found when they are in use. Support has also been added to support
6478 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
6480 Fixed a bug in fsck which caused it not deal properly with 16
6481 byte long filesystem labels.
6483 Fsck's -t option has been made a lot more flexible. The semantics for
6484 what happens if a comma-separated list to fsck has been regularized,
6485 and it is now possible to filter what filesystems will get checked
6486 based what is in the filesystem's fstab entry's option field. (Debian
6489 The dumpe2fs program can now print out the group description
6490 information in hex, and also prints the location of the superblock and
6491 block group descriptor for those block groups that have them.
6493 Mke2fs now clears the ext2 superblock before it starts creating a
6494 filesystem, so that the superblock magic number is only written if the
6495 filesystem creation process successfully completes.
6497 The debugfs program's stat command now pretty-prints the blocks used
6498 by an inode so that it's more compact and informative.
6500 The debugfs stats command now uses the same libe2p code (which is used
6501 by dumpe2fs) to print the superblock header information. This is more
6502 complete, and it avoids a bit of code duplication.
6504 Added a new debugfs command, set_super_value (ssv) which allows the
6505 user to set arbitrary superblock fields.
6507 Debugfs was extended to support inode numbers in hex (by prefixing
6508 them with 0x), and so that modify_inode can set the inode generation
6509 number. Also, there is now a new function command called logdump
6510 which will dump an ext3 journal.
6512 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
6515 Debugfs's dump command now stops immediately upon reporting a disk
6516 read error. (Fixed a bug in ext2fs_file_read library routine which
6517 caused debugfs not to stop.) (Debian bug #79163)
6519 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
6520 checked before /etc/mtab is used, since /proc/mounts is more likely to
6523 Added portability fixes for Solaris and Linux/ia64.
6525 Various manual pages were clarified and cleaned up. (Fixed debian
6526 bugs #63442, #67446, and #87216)
6532 The e2fsck message printer now supports %Iu and %Ig, which will print
6533 out the inode's user and group owners, respectively.
6535 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
6536 that no longer dependent on the system having the correct version of
6537 the kernel header files.
6539 Added a new function to libext2, ext2fs_find_block_device(), which
6540 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
6541 device given its device number.
6543 Added a new function to libext2, ext2fs_sync_device, which centralizes
6544 all of the places which might try to use the BLKFLSBUF or FDFLUSH
6545 ioctls (and usually failing to define them since the system header
6546 files don't usually do this for us, and we're trying to avoid usage of
6547 kernel include files now).
6549 Added new utility programs in tests/progs: random_exercise and
6550 hold_inode. They aren't built by default; they're useful for
6551 exercising ext3 filesystem code.
6553 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
6554 the filesystem close functions to only update the superblock, and to
6555 not touch the block group descriptors. Needed by tune2fs when
6556 modifying a mounted filesystem.
6558 Got rid of struct ext2fs_sb and replaced it with the standard struct
6559 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
6560 source (but not binary) compatibility of some users of the ext2
6561 library. Those applications should just simply do a global search and
6562 replace of struct ext2fs_sb with struct ext2_super_block, and include
6563 the new header file <ext2fs/ext2_fs.h> which defines it.
6565 The ino_t type has been renamed ext2_ino_t to protect applications
6566 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
6567 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
6568 unexpected ABI change.
6570 The Makefiles have been reworked so that "make check" can be run from
6571 the top-level Makefile.
6573 Fix general gcc -Wall complaints and removed dead code.
6575 Remove use of NOARGS, because we assume everyone does ANSI C these
6578 Added build-rpm script from sct.
6580 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
6583 New function ext2fs_flush_icache which must be called if the
6584 application program modifies the inode table blocks without going
6585 through ext2fs_write_inode() interface.
6587 New ext2fs_check_mount_point() function, which will return the mount
6588 point of a device if mounted.
6590 The io_channel abstraction now has an optional interface,
6591 io_channel_write_range, which allows specific byte ranges to be
6594 The unix_io IO channel now supports write-through caching, so that
6595 journal creation is more efficient.
6597 Added x86 assembly language routines to support byte swapping, to
6598 reduce executable size.
6600 Fixed bug in the utility program subst so that it's possible to
6601 replace a substitution variable with a zero-length string.
6603 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
6604 slipped into some of the problem number.
6606 E2fsprogs 1.19 (July 13, 2000)
6607 ==============================
6609 Release the resize2fs program since the timeout before it could
6610 be released under the GPL has finally expired.
6612 Add experimental support needed for the ext2 compression patches.
6613 This requires compiling e2fsprogs with the --enable-compression flag
6614 to the configure script.
6616 Added ext3 journalling support. E2fsck will run the journal (if
6617 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
6618 installed as a symlink to e2fsck. Fsck has been taught about ext3,
6619 and treats it the same as ext2 in terms of the progress bar logic.
6620 Dumpe2fs will display the superblock journaling information if the
6621 filesystem has a journal. The ext2 library will now permit opening an
6622 ext3 filesystem with the recovery flag set. This is necessary for
6623 on-line dump's to work correctly, but there may be issues with this
6624 working well since ext3 is much less agressive about syncing blocks to
6625 the filesystem, since they're safe on the journal.
6627 Tune2fs and e2fsck have been changed to allow the mount_count check to
6628 be disabled by setting max_mount_count to -1. (This was already
6629 supported by the kernel.)
6631 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
6632 are used for ext3 as well.
6634 Added internationalization support for e2fsprogs; must be enabled
6635 by passing --enable-nls to configure.
6637 Always use the provided ext2fs header files to insulate ourselves from
6638 kernel version changes. Which include files are used by e2fsprogs
6639 have also been cleaned up to improve portability.
6641 Limit the number of times that e2fsck updates the progress bar so that
6642 people who are booting using a 9600 baud console don't get swampped by
6645 Improved the loop detection algorithm in e2sck's pass #3 so that it is
6646 much, much faster for large filesystems with a large number of
6649 The memory footprint for e2fsck is now slightly smaller than before.
6651 E2fsck now checks if special devices have a non-zero size, and offers
6652 to clear the size field if it finds such an inode.
6654 E2fsck now checks if special devices have the append-only flag set,
6655 and offers to clear the inode.
6657 E2fsck now properly handles some "should never fail" cases during a
6658 bitmap copy in pass5.
6660 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
6662 E2fsck now calculates the correct location of the backup superblock in
6663 the case of filesystem blocksizes > 1k.
6665 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
6666 which normally didn't cause problems under most filesystem parameters,
6667 but could cause a valid superblock to be rejected in extreme cases.
6668 Other checks for validating superblock values were made more
6671 Added non-destructive write testing to the badblocks program, courtesy
6672 of David Beattie. The badblocks also now has an option to input the
6673 current set of bad blocks, so that known bad blocks are skipped to
6674 speed up the badblocks test. There is also a persistent rescan
6675 feature which causes badblocks to run until it has completed some
6676 number of passes without discovering any new bad blocks.
6678 Badblocks now checks to see if the device is mounted and refuses to do
6679 the tests involving writing to the device if it is mounted. Also,
6680 badblocks now allows the number of blocks to be checked to be
6681 defaulted to the size of the partition.
6683 Fixed a bug in fsck which didn't allow non-root users to be able to
6684 check filesystems if there were any LABEL= or UUID= entries in
6687 The Hurd doesn't support the filetype filesystem feature. The mke2fs
6688 program now makes sure that for the Hurd, the filestype feature is
6689 turned off. E2fsck will check to see if the filetype feature is
6690 turned on for Hurd filesystems, and offer to turn off the feature.
6692 Mke2fs now has a safety check to make sure the number of blocks do not
6693 exceed 32 bits even on a 64 bit platform.
6695 Really fixed a bug in fsck to allow "fsck -As" to run interactive
6696 fsck's. (For those people who like to do interactive fsck's in the
6699 Debugfs has a few new features: the rdump command, which will do a
6700 recursive dump of a directory and all of its contents, and the lcd
6701 command which does a local chdir (much like the ftp command of the
6702 same name). In addition, the debugfs program and the open_filesystem
6703 command now takes three new options: -b and -s, which allows the
6704 blocksize and superblock location to be specified, and the -c option
6705 which is used in catastrophic situations where the block group
6706 descriptors are corrupt. If the -c option is specified, debugfs will
6707 skip trying to read in the block and inode bitmaps.
6709 Debufs's lsdel command was fixed to handle bad blocks in the inode
6712 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
6715 General improvements in error messages
6717 - Mke2fs prints a sane error message if the partition size is zero
6718 (usually because the partition table wasn't reread by the
6719 kernel due to the partition being busy), instead of "invalid
6720 argument passed to ext2 library while initializing superblock".
6722 - Fsck now prints more self-explanatory message if an invalid UUID=
6723 or LABEL= specification is passed to it.
6725 UUID library changed to use the LGPL.
6727 Fixed a bug in the UUID library where very rapid calls to the
6728 time-based UUID generator could cause duplicate UUID's to be returned.
6729 This was not a problem for e2fsprogs, but it could be a problem for
6730 other users of the library.
6732 Make the UUID library more robust in the face of missing or an
6733 improper /dev/urandom or /dev/random files.
6735 Added some random portability fixes for Solaris.
6737 Some minor man page updates.
6739 Fixed a memory leak in the ss library.
6745 We now try to use lseek64 and open64 from the LFS if possible.
6747 The 3rd parameter in e2p's print_flags is now a flags word, instead of
6750 The mark and unmark bitmap functions now return the previous state of
6751 the bit that was being changed, which is useful for some speed
6754 The following functions have been added to enhance the badblocks list
6755 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
6756 ext2fs_badblocks_equal.
6758 The ext2 header files now have the latest journalling fields to the
6761 The ext2fs_mkdir function in libext2fs now properly backs out of error
6762 conditions robustly.
6764 Cleaned up makefiles:
6765 - to cleanly compile with the -j flag.
6766 - so distclean removes all generated files.
6767 - so in case of an error while installing header files, the make aborts.
6769 Fix test_script so that it works correctly when compiling in the
6772 The random UUID generation routine has been made slightly better in
6773 the case where /dev/random doesn't exist. (Use of randomly-based UUID
6774 is still not recommended if /dev/random doesn't exist, however; it's
6775 better to use the time/ethernet MAC address UUID in this case.)
6777 Clean up the build process so it's more friendly in case of missing
6780 The ext2fs header file can now be #include'd into C++ programs.
6782 The e2p.h header file is now installed.
6784 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
6788 E2fsprogs 1.18 (November 10, 1999)
6789 ==================================
6791 Fix a core dumping bug in e2fsck if an imagic inode is present or
6792 (more rarely) if the filesystem is badly corrupted enough that e2fsck
6793 has to restart pass 1 processing. E2fsck now closes the filesystem
6794 before freeing a large number of its data structures, so in the case
6795 of future memory faults, at least the fixed filesystem will be fully
6798 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
6799 imagic inode, it will offer to clear the imagic flag.
6801 E2fsck will now offer to clear the immutable flag on special files
6802 (device/socket/fifos) when running it in non-preen mode.
6804 E2fsck will now set the filetype when creating /lost+found, and when
6805 connected orphaned inodes to /lost+found.
6807 Debugfs's ncheck and icheck commands now handles the case where there
6808 are bad blocks in the inode table without bombing out.
6810 The badblocks list processing code has been made more efficiently for
6811 appending a large number of (ordered) badblocks to the badblocks list.
6813 Some minor man page updates.
6815 Fsck now allows interactive e2fsck's when using fsck -As (not a common
6816 mode, but some people like to do this in boot scripts for silly reasons).
6821 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
6822 with the problem code convention.
6824 The badblocks list regression test program has been updated to work
6825 with previously made API name changes.
6827 The ext2fs_free() command now uses the new badblocks API to avoid
6828 using the compatibility layer.
6830 Added new regression test cases; the run_e2fsck test script now
6831 supports the ability for a test case to run a prepratory command
6832 before running e2fsck.
6834 E2fsprogs 1.17 (October 26, 1999)
6835 =================================
6837 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
6840 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
6841 thus potentially causing problems if a binary UUID contained a NULL
6844 E2fsck now uses stricter checks for directory entries in pass 2:
6845 zero-length filenames are not allowed; neither are 8 byte long
6848 The debugfs "dirty" command now clears the filesystem valid bit.
6849 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
6850 bit in the in-core superblock image. The new functionality is more
6851 what the user expects, and is more useful.)
6853 Added a debugging hook to test parallel fsck; if the environment
6854 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
6855 will be checked in parallel when they normally would not be.
6860 Fixed some #ifdef's for compilation under the Hurd OS.
6862 Fixed minor W2K compatibility problems.
6864 Fixed some miscellaneous GCC warnings.
6867 E2fsprogs 1.16 (October 22, 1999)
6868 =================================
6870 Fixed a race condition bug in fsck; when printing a progress bar, if
6871 checking multiple filesystems in parallel, it was possible for fsck to
6872 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
6873 handler, which would cause it to terminate with a signal 10.
6875 E2fsck now properly handles filesystems that have the
6876 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
6877 filesystem into using or not using FILETYPE feature.
6879 E2fsck now properly handles filesystems that have the IMAGIC feature
6880 turned on (this is used on Linux AFS servers).
6882 The mke2fs program now creates filesystems that have the filetype and
6883 sparse_superblock features enabled by default, unless it is run on a
6884 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
6885 so there is now a new flag -O which allows the user to specify with
6886 which features she would like to create the filesystem; "mke2fs -O
6887 none" will create a filesystsem compatible with 2.0 kernels.
6889 The tune2fs program now has a -O option which allows the user to set
6890 and reset "safe" filesystem features. Currently, the only ones which
6891 allows to be modified are the filetype and sparse_superblock features.
6892 Note setting or clearing either feature will require running e2fsck on
6893 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
6894 requires that there is enough free space on the filesystem for the
6895 extra superblocks which will be created by e2fsck.)
6897 Debugfs can now set and print filesystem features in the superblock
6898 using the "features" command. Dumpe2fs will print out the complete
6899 set of features when listing the superblock.
6901 Dumpe2fs has new options -f (force) and -h (header-only).
6903 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
6904 message to come up. This could happen when decrementing or
6905 incrementing a link count could result in an overflow.
6907 Fixed a bug in e2fsck where the block count on the lost+found
6908 directory would not be properly incremented when the directory was
6909 expanded to the point where an indirect block needed to be allocated.
6911 E2fsck now makes some additional sanity checks on the superblock to
6912 avoid crashing or giving a memory allocation error if some of the
6913 values in the superblock are unresonable (but the superblock otherwise
6916 Fixed a bug in e2fsck where a very badly corrupted filesystem might
6917 require two passes to completely fix the filesystem. This happened if
6918 an inode claimed blocks that was part of the filesystem metadata
6919 (typically, when garbage was written into an inode table or indirect
6920 block, since this kind of filesystem corruption normally doesn't
6923 On the Alpha, glibc declares st_flags although it isn't actually used;
6924 the configure script was improved to detect this case so that
6925 e2fsprogs can avoid using the non-functional stat field.
6927 The manual pages were updated to use a more consistent formatting
6928 style consistent with standard Unix man pages. Mke2fs's man page
6929 added documentation for a few previously undocumented options.
6931 Fixed minor display bugs in tune2fs and mke2fs.
6936 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6938 Added features to parse and print feature strings into the e2p library.
6939 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6941 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6942 whose directory entries contain proper filetype information if the
6943 filesystem supports it.
6945 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6946 the directory entry filetype information. This is used to set the
6947 directory entry filetype information if the filesystem supports it.
6949 Fixed a bug in ext2fs_expand_dir() where the block count in a
6950 directory's inode would not be properly incremented when the directory
6951 was expanded to the point where an indirect block needed to be
6955 E2fsprogs 1.15 (July 18, 1999)
6956 ==============================
6958 Add configuration checks so that e2fsprogs will compile cleanly on
6959 Linux 2.3 kernels that have renamed i_version to i_generation.
6961 E2fsck now prints a progress/completion bar (and not just a simple
6962 spinner) if the -C0 option is requested or if it receives a SIGUSR1
6963 signal. Fsck will automatically manage the (potentially muliple)
6964 e2fsck processes to print completion bars if it is given a -C option,
6965 with the right thing happening if multiple filesystems are being
6966 checked in parallel.
6968 Mke2fs now has better automatic hueristics to determine the filesystem
6969 parameters to be used for a particular filesystem. Added a new option
6970 -T which allows the user to specify how the filesystem is to be used,
6971 which helps mke2fs do a better job selecting the filesystem parameters.
6973 Mke2fs now creates revision 1 filesystems by default, and with the
6974 sparse superblock feature enabled. The sparse superblock feature is
6975 not understood by Linux 2.0 kernels, so they will only allow read-only
6976 mounts of filesystems with this sparse superblocks.
6978 Fix bug where if /dev/null couldn't be opened (should never happen),
6979 e2fsck would hang in a tight loop.
6981 Make e2fsck handle the case where /lost+found isn't a directory.
6983 E2fsck now uses mallinfo if it exists to get accurate statistics about
6986 Fix bug in e2fsck where it wouldn't check to see if a disconnected
6987 inode had any problems before connecting it to /lost+found.
6989 Add check to e2fsck so it makes sure that total number of inodes in
6990 the filesystem is a sane number.
6992 Fix fencepost error when clearing an the end of the block bitmap which
6993 caused the last block in the bitmap not to get cleared.
6995 Cleaned up a number of messages in e2fsck:
6996 * The message "Group's #'s copy of the group descriptor..."
6997 was fixed so that the correct number would be displayed.
6998 * Added missing space in the "disk write-protected" error messsage
6999 * Cleaned up the error message printed when a non-interactive
7000 e2fsck needs to abort a check because the filesystem
7001 appears to be mounted.
7003 Added a new command-line utility, uuidgen, which will create and print
7006 Make debugfs's icheck command more robust by checking to make sure an
7007 inode has valid blocks before interarting over the inode's blocks.
7009 UUID generation now uses a random-based scheme whenever possible to
7010 prevent potential privacy problems.
7012 Man pages for all of the UUID functions in the lirbary were added.
7014 Fixed bug in fsck so it won't coredump if a filesystem not in
7015 /etc/fstab is given to it.
7017 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
7018 that most of the other mount utilities understands.
7020 Mke2fs will make a filesystem even if it appears mounted if the force
7023 Dumpe2fs has new command-line options which allow a filesystem expert
7024 to specify the superblock and blocksize when opening a filesystem.
7025 This is mainly useful when examining the remains of a toasted
7028 The badblocks program has been updated to display correctly on disks
7029 with large block numbers.
7031 The badblocks program no longer gives spurious errors when errors
7032 occur on non-block boundaries, which is common if the blocksize is
7035 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
7036 MKE2FS_SYNC environment variable is set. This is to work around a VM
7037 bug in the 2.0 kernel. I've heard a report that a RAID user was able
7038 to trigger it even using a 2.2 kernel, but hopefully it will not be
7039 needed for most Linux 2.2 users.
7041 Fixed miscellaneous documentation and man pages.
7046 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
7047 in e2fsck's pass1.c really should have been static.
7049 The return value of the uuid_compare() function was changed to make it
7050 match with the convetions used by strcmp, memcmp, and Paul Leach's
7051 UUID sample document.
7053 The "make depend" process has now been made more automated; it now
7054 automatically word-wraps the dependencies, and only replaces source
7055 Makefile.in if there has been a change in the dependencies. Also, a
7056 top-level "make depend" now recurses through all the subdirectories
7059 The Makefile in .../util has been changed so that subst is built using
7060 the native C compiler during a cross-compilation, since the subst
7061 program is only used during the build process. Also add an explicit
7062 rule to build util/subst by cd'ing to the correct directory and
7065 The man directories are defined in terms mandir, so that the configure
7066 script can override the location of the manual pages.
7068 The config files have been updated to recognize new machine types for
7069 both the i386 and alpha families.
7071 Fsck has been modified so that it will accurately create an
7072 fsck_instance even when the noexecute flag is set. This allows for
7073 accurate debugging of the fsck pass structure. Also, when the verbose
7074 flag is given twice, fsck will print debugging information about when
7075 fsck is waiting for jobs to finish.
7078 E2fsprogs 1.14 (January 9, 1999)
7079 ================================
7081 Fix the fstab parsing code so that it can handle blank lines and
7082 comment characters. Also, missing pass numbers need to be treated as
7085 Fixed a bug in e2fsck where under some circumstances (when e2fsck
7086 needs to restart processing after fixing an egregious inconsistency)
7087 it would try to access already freed memory.
7089 E2fsck now prints non-printable characters in directory entries and
7090 pathnames using '^' and 'M-' notation.
7092 Fixed chattr so that it will ignore symbolic links when doing
7093 recursive descent traversals. For both chattr and lsattr, no longer
7094 print the version string unless the -V option is given.
7096 Allow the system administrator to directly specify the number of
7097 inodes desired in the filesystem, for some special cases where this is
7100 Fix portability problems so that e2fsprogs can be compiled under Linux
7101 1.2 systems and Solaris systems.
7103 Update the config.guess file with a more recent version that will
7104 identify newer Linux platforms.
7109 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
7110 an inode number of zero is passed to them.
7112 E2fsprogs 1.13 (December 15, 1998)
7113 ==================================
7115 Fixed a bug in debugfs where an error messages weren't getting printed
7116 when the ext2 library routines to read inodes returned errors in the
7117 stat, cmri and rm commands.
7119 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
7120 provided, it won't create an inode table smaller than the minimum
7121 number of inodes required for a proper ext2 filesystem.
7123 Fsck now parses the /etc/fstab file directly (instead of using
7124 getmntent()), so that it can distinguish between a missing pass number
7125 field and pass number field of zero. This caused problems for
7126 diskless workstations where all of the filesystems in /etc/fstab have
7127 an explicit pass number of zero, and fsck could not distinguish this
7128 from a /etc/fstab file with missing pass numbers.
7130 E2fsck will create a /lost+found directory if there isn't one in the
7131 filesystem, since it's safer to create the lost+found directory before
7134 Fixed e2fsck so that it would detect bogus immutable inodes which
7135 happen to be sockets and FIFO files, and offer to clear them.
7137 If a filesystem has multiple reasons why it needs to be checked, and
7138 one of the reasons is that it is uncleanly mounted, e2fsck will print
7139 that as the reason why the filesystem is being checked.
7141 Cleaned up the output routines of mke2fs so that it doesn't overflow
7142 an 80 column display when formating really big filesystems.
7144 Added a sanity check to e2fsck to make sure that file descriptors 0,
7145 1, 2 are open before opening the hard disk. This avoids a problem
7146 where a broken program might exec e2fsck with those file descriptors
7147 closed, which would cause disastrous results if the kernel returns a
7148 file descriptor for the block device which is also used by FILE *
7151 Fixed up the e2fsck progress reporting functions so that the values
7152 reliably reach 100% at the completion of all of the e2fsck passes.
7154 Fixed minor documentation bugs in man pages and usage messages.
7159 Fixed a number of lint warnings in the ext2fs library and potential
7160 portability problems from other OS's header files that might define
7161 CPP macros for names like "max" and "min".
7163 ext2fs_badblocks_list_add() has been made more efficient when it needs
7164 to grow the bad blocks list.
7166 Fixed a bug in e2fsck which caused it to dereference a freed pointer
7167 just before exiting.
7169 Fixed the substition process for generating the mk_cmds and compile_et
7170 scripts so that they will work outside of the build tree.
7172 Add sanity check to e2fsck so that if an internal routine
7173 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
7174 and causing a core dump. This should never happen, but...
7176 E2fsprogs 1.12 (July 9, 1998)
7177 ==================================
7179 E2fsprogs now works with glibc (at least with the version shipped wtih
7180 RedHat 5.0). The ext2fs_llseek() function should now work even with
7181 i386 ELF shared libraries and if llseek() is not present. We also
7182 explicitly do a configure test to see if (a) llseek is in libc, and
7183 (b) if llseek is declared in the system header files. (See standard
7184 complaints about libc developers don't understand the concept of
7185 compatibility with previous versions of libc.)
7187 The ext2fs library now writes out the block group number in each of
7188 the superblock copies. This makes it easier to automatically
7189 determine the starting block group of the filesystem when the block
7190 group information is trashed.
7192 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
7193 which means that e2fsprogs will ignore the high 8 bits of the
7194 directory entry's name_len field, so that it can be used for other
7197 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
7198 E2fsprogs will now support filesystems with 64-bit sized files.
7200 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
7202 Added new program "e2label", contributed by Andries Brouwer. E2label
7203 provides an easy-to-use interface to modify the filesystem label.
7205 Fixed bug so that lsattr -v works instead of producing a core dump.
7207 Fixed a minor bug in mke2fs so that all groups with bad superblock
7208 backup blocks are printed (not just the first one).
7210 Mke2fs will check the size of the device, and if the user specifies a
7211 filesystem size larger than the apparent size of the device it will
7212 print a warning message and ask if the user wants to proceed.
7214 E2fsck has a new option -C, which sends completion information to the
7215 specified file descriptor. For the most part, this is intended for
7216 programs to use, although -C 0 will print a spinning character to the
7217 stdout device, which may be useful for users who want to see something
7218 happening while e2fsck goes about its business.
7220 Fixed a bug in e2fsck which could cause a core dump when it needs to
7221 expand the /lost+found directory, and sometimes the bitmaps haven't
7222 been merged in. Also fixed a related bug where ext2fs_write_dir_block
7223 was used to write out a non-directory block. (Which would be bad on a
7224 non-Intel platform with byte swapping going on.)
7226 Fixed bug in e2fsck where it would print a "programming error" message
7227 instead of correctly identifying where a bad block was in used when
7228 the bad block was in a non-primary superblock or block group
7229 descriptor. Also fixed a related bug when sparse superblocks are in
7230 use and there is a bad block where a superblock or block group
7231 descriptor would have been in a group that doesn't include a
7234 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
7235 the block group descriptor table is corrupt, it was possible to try to
7236 allocate a huge array, fail, and then abort e2fsck.
7237 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
7238 and subsitutes reasonable values if the descriptors are obviously bogus.
7240 If e2fsck finds a device file which has the immutable flag set and the
7241 i_blocks beyond the normal device number are non-zero, e2fsck will
7242 offer to remove it, since it's probably caused by garbage in the inode
7245 When opening a filesystem, e2fsck specially checks for the EROFS error
7246 code, and prints a specific error message to the user which is more
7249 If the filesystem revision is too high, change the e2fsck to print
7250 that this is either because e2fsck is out of date, or because the
7251 superblock is corrupt.
7253 E2fsck now checks for directories that have duplicate '.' and '..'
7254 entries, and fixes this corruption.
7256 E2fsck no longer forces a sync of the filesystem (with attendant sleep
7257 calls) at all times. The ext2fs_flush() function now performs a sync
7258 only if it needed to write data blocks to disk.
7260 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
7261 certain errors would not be properly reported.
7263 Updated and expanded a few points in the man pages which users
7264 complained wheren't explicit enough.
7266 Added special case byte-swapping code if compiling on the PowerPC, to
7267 accomodate the strange big-endian variant of the ext2 filesystem that
7268 was previously used on the PowerPC port.
7274 Removed C++ keywords from the ext2fs libraries so that it could be
7277 E2fsck's internal organization has now been massively reorganized so
7278 that pass*.c don't have any printf statements. Instead, all problems
7279 are reported through the fix_problem() abstraction interface. E2fsck
7280 has also been revamped so that it can be called as a library from a
7283 Added new fileio primitives in libext2fs for reading and writing
7284 files on an unmounted ext2 filesystem. This interface is now used by
7287 Added a new libext2fs function for mapping logical block numbers of
7288 a file to a physical block number.
7290 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
7291 a block, zeros it, and updates the filesystem accounting records
7294 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
7295 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
7297 The libext2fs functions now use a set of memory allocation wrapper
7298 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
7299 instead of malloc, free, and resize. This makes it easier for us to
7300 be ported to strange environments where malloc, et. al. aren't
7301 necessarily available.
7303 Change the libext2fs fucntion to return ext2-specific error codes
7304 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
7305 and depending on the existence of system error codes (such as EEXIST
7308 Renamed io.h to ext2_io.h to avoid collision with other OS's header
7311 Add protection against ext2_io.h and ext2fs.h being included multiple
7314 The types used for memory lengths, etc. have been made more portable.
7315 In generla, the code has been made 16-bit safe. Added Mark
7316 Habersack's contributed DOS disk i/o routines.
7318 Miscellaneous portability fixes, including not depending on char's
7321 The io_channel structure has a new element, app_data, which is
7322 initialized by the ext2fs routines to contain a copy of the filesystem
7325 ext2fs_check_directory()'s callback function may now return the error
7326 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
7327 really do the checking, despite the presence of the callback function.
7330 E2fsprosg 1.11 (June 17, 1997)
7331 ==============================
7333 Fixed e2fsck to detect (previously ignored) conflicts between the
7334 superblock or block group descriptors and block bitmaps, inode
7335 bitmaps, and inode tables.
7337 Fixed bug in e2fsck so that when the message printed out when a block
7338 or inode bitmap conflicts with other data, it has the correct group
7341 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
7342 to badblocks. This meant that not all of the filesystem was being
7343 tested for bad blocks!
7345 Fixed an array boundary overrun case which cropped up in
7346 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
7349 Adjusted the number of columns printed by mke2fs when displaying the
7350 superblock backups to avoid running over 80 columns when making a
7351 really big filesystem.
7353 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
7354 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
7355 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
7360 Fixed install rule in lib/ss so that ss_err.h is actually getting
7363 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
7364 bassed back to the caller.
7366 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
7367 setting the current inode number (which meant this function wasn't
7370 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
7371 blocks in the bitmap when increasing the size of the bitmap.
7373 Changed the initial number of blocks allocated by ext2fs_init_dblist()
7374 to be more realistic.
7376 Added a new function ext2fs_allocate_group_table, which sets up the
7377 group descriptor information (and allocates inode and block bitmaps,
7378 and inode tables for a particular group). The function was created by
7379 factoring out code form ext2fs_allocate_tables().
7381 Added a new function ext2fs_move_blocks which takes a bitmap of the
7382 blocks to be moved, and moves them to another location on the
7385 Make the unix_io channel's io_channel_flush implementation calls sync()
7386 to to flush the kernel buffers to disk.
7388 Added a new function ext2fs_dblist_count returns the number of
7389 directory blocks in dblist.
7392 E2fsprogs 1.10 (April 24, 1997)
7393 ===============================
7395 Mke2fs once again defaults to creating revision #0 filesystems, since
7396 people were complaining about breaking compatibility with 1.2 kernels.
7397 Warning messages were added to the mke2fs and tune2fs man pages that
7398 the sparse superblock option isn't supported by most kernels yet (1.2
7399 and 2.0 both don't support parse superblocks.)
7401 Added new flag to mke2fs, -R <raid options>, which allows the user to
7402 tell mke2fs about the RAID configuration of the filesystem. Currently
7403 the only supported raid option is "stride" which specifies the width
7406 Fixed bug in e2fsck where pass1b would bomb out if there were any
7407 blocks marked bad in the inode table.
7409 Fixed rare bug in mke2fs where if the user had a very unlucky number
7410 of blocks in a filesystem (probability less than .002) the resulting
7411 filesystem would be corrupt in the last block group.
7413 Fixed bug where if e2fsck tried to allocate a block to fix a
7414 filesystem corruption problem and the filesystem had no free blocks,
7415 ext2fs_new_block() would loop forever.
7417 The configure script now checks explicitly to see if "-static" works,
7418 since that can't be assumed to be true --- RedHat doesn't install
7419 libc-static by default.
7421 Fixed bug in libext2's block iterator functions where under some
7422 cirmcustances, file with holes would cause the bcount parameter to the
7423 callback function to be incorrect. This bug didn't affect any of
7424 e2fsprogs programs, but it was discovered by Paul Mackerras, the
7425 author of the PPC boot loader.
7427 Removed use of static variables to store the inode cache in libext2fs.
7428 This caused problems if more than one filesystem was accessed via
7429 libext2fs (static variables in libraries are generally a bad idea).
7430 Again, this didn't affect e2fsprogs programs, but it was discovered by
7433 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
7434 will compile cleanly with 1.2.13 kernels (even with a.out shared
7440 Added new functions to duplicate an ext2 filesystem handle, and its
7441 associated substructure. New functions: ext2fs_dup_handle(),
7442 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
7443 Other structures, such as the io_channel and the inode_cache, now have
7444 a ref count so that they only get freed when they are no longer used
7445 by any filesystem handle. (These functions were added as part of the
7446 development effort for an ext2 resizer).
7448 E2fsprogs 1.09 (April 14, 1997)
7449 ===============================
7451 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
7452 accidentally introduced in the 1.08 release. The overhead calculation
7453 was accidentally removed, which caused ext2fs_initialize() to not
7454 notice when the filesystem size needed to be adjusted down because
7455 there wasn't enough space in the last block group.
7457 Fixed bug in version parsing library routine; it was always parsing
7458 the library version string, instead of using the passed-in string.
7460 Clarified chattr man page.
7462 E2fsprogs 1.08 (April 10, 1997)
7463 ===============================
7465 E2fsck 1.07 was very slow when checking very large filesystems with a
7466 lot of files that had hard links (i.e., news spools). This was fixed
7467 by seriously revamping the icount abstraction. Added a formal test
7468 suite for the icount abstraction.
7470 Debugfs now has a "-l" option to the "ls" command, which lists the
7471 inode number, permissions, owner, group, size, and name of the files
7474 Fix a bug in e2fsck where when a directory had its blocks moved to
7475 another location during the pass 1b processing, the directory block
7476 list wasn't updated, so pass 2 wouldn't check (and correct) the
7477 correct directory block.
7479 E2fsck will now treat inodes which contain blocks which are claimed by
7480 the filesystem metadata by treating them as multiply claimed blocks.
7481 This way, the data in those blocks can be copied to a new block during
7482 the pass 1b--1d processing.
7484 E2fsck will attempt to determine the correct superblock number and
7485 display it in the diagnostic and warning messages if possible.
7487 Add support for a new (incompatible) feature, "sparse_super". This
7488 feature reduces the number of blocks which contain copies of backup
7489 superblocks and block group descriptors. (It is only an incompatible
7490 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
7491 support a new -s option; e2fsck will recognize filesystems built with
7492 this feature turned on.
7494 E2fsck now checks the library to make sure is the correct version,
7495 using new library functions. (This helps to diagnose incorrectly
7496 installed e2fsprogs distributions.)
7498 Dumpe2fs now prints more information; its now prints the the
7499 filesystem revision number, the filesystem sparse_super feature (if
7500 present), the block ranges for each block group, and the offset from
7501 the beginning of the block group.
7503 Mke2fs now distributes the inode and block bitmap blok so that the
7504 won't be concentrated in one or two disks in RAID/striping setups.
7505 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
7506 choose the largest blocks per group that be chosen. (For 2k blocks,
7507 you can have up to 16384 blocks/group; for 4k blocks, you can have up
7508 to 32768 blocks/group.) Previously mke2fs would not allow
7509 specification of more than 8192 blocks per group, even if you were
7510 using a 2k or 4k block group.
7515 Added a new function ext2fs_create_icount2() which takes a "hint"
7516 argument. This hint argument presets the icount array with the list
7517 of inodes which actually need to be in the icount array. This really
7518 helps to speed up e2fsck.
7520 Added a new function ext2fs_icount_validate() which checks the rep
7521 invariant for the icount structure. This is used mostly for testing.
7523 The error mesasage given when a bad inode number is passed to
7524 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
7525 EXT2FS_UNMARK_ERROR).
7527 Added a new function ext2fs_set_dir_block which sets the block of a
7528 dblist entry, given the directory inode and blockcnt.
7530 Added a new function ext2fs_get_library_version() which returns the
7531 current library version, and ext2fs_parse_version_string() which
7532 returns a version number based on a e2fsprogs version string.
7534 The icount functions will return EINVAL if the passed in inode number
7537 E2fsprogs 1.07 (March 9, 1997)
7538 ==============================
7540 E2fsck is now uses much less memory when checking really large
7541 filesystems (or rather, filesystems with a large number of inodes).
7542 Previously a filesystem with 1 million inodes required 4 megabytes of
7543 memory to store inode count statistics; that storage requirement has
7544 now been reduced to roughly half a megabyte.
7546 E2fsck can now properly deal with bad blocks appearing inside the
7547 inode table. Instead of trying to relocate the inode table (which
7548 often failed because there wasn't enough space), the inodes in the bad
7549 block are marked as in use.
7551 E2fsck will automatically try to use the backup superblocks if the
7552 primary superblocks have a bad magic number or have missing meta-data
7553 blocks (or meta-data blocks which are out of range).
7555 E2fsck's pass 3 has been made more efficient; most noticeable on
7556 filesystems with a very large number of directories.
7558 Completely revamped e2fsck's system of printing problem reports. It
7559 is now table driven, to make them more easily customizeable and
7560 extendable. Error messages which can be printed out during preen mode
7561 are now one line long.
7563 Fixed e2fsck's filesystem swapping code so that it won't try to swap
7564 fast symbolic links or deleted files.
7566 Fixed e2fsck core dumping when fixing a filesystem which has no
7567 directories (not even a root directory).
7569 Added a check to e2fsck to make sure that the length of every
7570 directory entry is a multiple of 4 (since the kernel complains if it
7573 Added a check to e2fsck to make sure that a directory entry isn't a
7574 link to the root directory, since that isn't allowed.
7576 Added a check to e2fsk to now make sure the '.' and '..' directory
7577 entries are null terminated, since the 2.0 kernel requires it.
7579 Added check to write_bitmaps() to make sure the superblock doesn't get
7580 trashed if the inode or block bitmap is marked as being block zero.
7582 Added checking of the new feature set fields in the superblock, to
7583 avoid dealing with new filesystem features that this package wasn't
7586 Fixed a fencepost error in ext2fs_new_block() which would occasionally
7587 try to allocate a block beyond the end of a filesystem.
7589 When the UUID library picks a random IEEE 802 address (because it
7590 can't find one from a network card), it sets the multicast bit, to
7591 avoid conflicting with a legitimate IEEE 802 address.
7593 Mke2fs now sets the root directory's owner to be the real uid of the
7594 user running mke2fs. If the real uid is non-zero, it also sets
7595 the group ownership of the root directory to be the real group-id of
7596 the user running mke2fs.
7598 Mke2fs now has more intelligent error checking when it is given a
7599 non-existent device.
7601 When badblocks is given the -vv option, it now updates the block that
7602 it is currently testing on every block.
7604 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
7605 currently correctly if PATH wasn't already set.
7607 Shared libraries now built with dependencies. This allows the shared
7608 library files to be used with dlopen(); it also makes the transition
7609 to libc 6 easier, since ld.so can tell which libc a particular shared
7610 library expects to use.
7615 Added new abstraction (defined in dblist.c) for maintaining a list of
7616 blocks which belongs to directories. This is used in e2fsck and other
7617 programs which need to iterate over all directories.
7619 Added new functions which test to see if a contiguous range of blocks
7620 (or inodes) are available. (ext2fs_*_bitmap_range).
7622 Added new function (ext2_inode_has_valid_blocks) which returns true if
7623 an inode has valid blocks. (moved from e2fsck code).
7625 Added new function (ext2fs_allocate_tables) which allocates the
7626 meta-data blocks as part of initializing a filesystem. (moved from
7629 Added a new I/O manager for testing purposes. It will either allow a
7630 program to intercept I/O requests, or print debugging messages to
7631 trace the activity of a program using the I/O manager.
7633 The badblocks_list functions now store the bad blocks in a sorted
7634 order, and use a binary search to speed up badblocks_list_test.
7636 The inode scan function ext2fs_get_next_inode() may now return a soft
7637 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
7638 those cases where part of an inode table is missing or there is a bad
7639 block in the inode table.
7641 Added a new function (ext2fs_block_iterate2) which adds new arguments to
7642 the callback function to return a pointer (block and offset) to the
7643 reference of the block.
7645 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
7646 application to jump to a particular block group while doing an inode
7649 The badblocks list functions were renamed from badblocks_* to
7650 ext2fs_badblocks_*. Backwards compatibility functions are available
7651 for now, but programs should be modified to use the new interface.
7653 Some of the library functions were reorganized into separate files to
7654 reduce the size of some programs which statically link against the
7657 Put in some miscellaneous fixes for the Alpha platform.
7660 E2fsprogs 1.06 (October 7, 1996)
7661 ================================
7663 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
7664 smash the backup copies in ext2fs_close(). (The problem was that when
7665 e2fsck -p discovered the problem, while it was closing the filesystem
7666 and exiting, it was also blowing away the backup superblocks on the
7667 disk, which was less than friendly.) We now make it the case that we
7668 only write out the backup superblock and the back block descriptors if
7669 the filesystem is completely free from problems.
7671 Fixed a bug in block_interate in the lib/ext2fs library which caused
7672 e2fsck to fail on GNU Hurd-created filesystems.
7674 Add support for Linux/FT's bootloader, which actually uses
7675 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
7678 Add support for the "A" (no atime update) attribute. (Note: this
7679 attribute is not yet in production kernels.)
7681 The test suite is not automatically run when doing a "make all" from
7682 the top level directory. Users should manually run "make check" if
7683 they wish to run the test suite.
7685 Upon a preenhalt(), make the printed message more explicit that
7686 running e2fsck "MANAULLY" means without the -p or -a options.
7688 In e2fsck, if a disconnected inode is zero-length, offer to clear it
7689 instead of offering to connect it to lost+found.
7691 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
7692 e2fsck to be run over it, change e2fsck to explicitly display this
7695 For dumpe2fs and e2fsck, cause the -V option to print out which
7696 version of the ext2fs library is actually getting used. (This will
7697 help detect mismatches of using a 1.06 utility with a 1.05 library,
7703 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
7704 the naming convention.
7706 In ext2fs_initialize(), make sure the description for the inode bitmap
7707 is correctly initialize.
7709 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
7711 E2fsprogs 1.05 (September 7, 1996)
7712 ==================================
7714 Add support for new fields in the ext2 superblock --- volume name,
7715 volume UUID, and last mounted field. Dumpe2fs displays these fields,
7716 tune2fs and mke2fs allows you to set them. E2fsck will automatically
7717 generate a UUID for those volumes that don't have them.
7719 Put in support for e2fsck to recognize HURD specific ext2 features ---
7720 most notably, the translator block. The e2fsprogs tools will now use
7721 the creator_os field in the superblock to correctly handle different
7722 OS-specific variants of the ext2 filesystem.
7724 E2fsck now fixes inodes which have a the deletion time set, but which
7725 have a non-zero i_link_count field by offering to clear the deletion
7726 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
7727 ext2 kernel behavior) and offered to unlink the file.
7729 If e2fsck sets the clean bit, but nothing else, set the exit code
7730 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
7731 set the filesystem valid bit when it was previously cleared. :-) This
7732 was needed to make the HURD fsck driver happy.
7734 If the user refuses to attach an unattached inode, e2fsck will no
7735 longer set the inode's link count. Otherwise, the inode would end up
7736 getting marked as unused, which might cause loss of data later.
7738 Make the message issued by e2fsck when the superblock is corrupt less
7739 confusing for users. It now mentions that another reason for the
7740 "corrupt superblock" message might be that the partition might not be
7741 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
7743 Make the libext2 library more robuest so that e2fsck won't coredump on
7744 an illegal superblock where the blocksize is zero. (f_crashdisk is
7747 By default, create filesystems where the default checkinterval is 6
7748 months (180 days). Linux servers can be robust enough that 20 reboots
7749 can be a long, long time.
7751 Added configure flag --enable-old-bitops, which forces the bitops to
7752 use the old (native) bitmask operations. By default on the sparc
7753 platform, the standard ext2 bit ordering is now used.
7755 Added a new feature to e2fsck to byte-swap filesystems; this can be
7756 used to convert old m68k filesystems to use the standard byte-order
7757 storage for the superblock, inodes, and directory blocks. This
7758 function is invoked by using the '-s' option to e2fsck.
7760 Debugfs's "dump" command has been enhanced so that it writes out the
7761 exact size of the file so that the nulls at the end of the file are
7762 eliminated. The command also accept a new "-p" option which will
7763 attempt preserve to preserve the ownernship, permissions, and
7764 file modification/access times.
7766 Debugfs has two new options, -f and -R. The -R option allows the user
7767 to execute a single debugfs command from the command line. The -f
7768 option allows the user to specify a "command file" containing debugfs
7769 commands which will get executed.
7771 Dumpe2fs now pretty prints the check interval, instead of just
7772 printing the check interval as a number of seconds.
7774 Fix bugs in debugfs: the params command when no filesystem is opened
7775 no longer causes a core dump. It is now possible to unlink a file
7776 when a pathame containing a '/' is specified.
7778 Tune2fs has a new -C option which sets the number of times the
7779 filesystem has been mounted.
7781 Fix the chattr '-v' option so that it actually works. Chattr was
7782 being buggy about the -v option parsing.
7787 The directory lib/uuid contains a set of library routines to generate
7788 DCE compatible UUIDs.
7790 Extended ext2fs_namei() to handle symbolic links. Added new function
7791 ext2fs_nami_follow() which will follow last symbolic link in the case
7792 where the pathname points to a sym link.
7794 The ext2fs_block_iterate function will now return the HURD translator
7795 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
7796 iterator to return data blocks only. The ext2fs.h file now defines
7797 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
7798 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
7799 count field of the iterator callback function.
7801 The test script driver now takes an optional second argument, which is
7802 the test case to be run. This allows you to run a test case without
7803 needing to run the entire test suite.
7805 On Linux ELF systems, install the .so files in the correct places
7806 (/usr/lib). The .so files must be stored in the same directory as the
7809 Fixed miscellaneous HURD compilation issues with header file being
7810 included in the right order.
7812 Fixed debugfs so that it resets optind to zero, not one, since setting
7813 optind to zero is more correct.
7816 E2fsprogs 1.04 (May 16, 1996)
7817 =============================
7819 First "official" (1.03 was a limited release only) to support building
7820 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
7823 This package includes a RPM specs file, that it can be built using the
7824 RedHat Package Manager.
7826 E2fsck now prints a hint that if there are lots of incorrectly located
7827 inode bitmaps, block bitmaps, and inode table blocks, the user might
7828 want to try using e2fsck -b 8193 first, to see if that fares any
7831 For ext2 filesystem written with the hurd, debugfs will now print out
7832 the translator field when printing an inode structure.
7834 Lots of miscellaneous linking/installation cleanups:
7836 Libraries are now linked using a relative pathname, instead of
7837 relying on -L working correct. It doesn't, in many cases, including
7838 current versions of GNU ld. This guarantees that the build tree is
7839 linking with the right libraries, instead of the ones installed in
7842 Header files, man pages, and the et/ss shell scripts are now
7843 generated using a custom substitution script, instead of relying on
7844 the configure script. This prevents needless recompilation of
7845 files; in addition, the custom substitution script is much faster.
7847 e2fsck may now be linked dynamically, by using the
7848 --enable-dynamic-e2fsck flag to configure. This is not recommended,
7849 since it increases e2fsck's dependence on other files, but some
7850 people need to save disk space, and other critical programs on their
7851 systems were being linked dynamically anyway.
7853 Programs such as fsck which didn't need to be linked against
7854 libext2fs (or mke2fs which didn't need to be linked against libe2p)
7855 only link against libraries they actually need. Otherwise, those
7856 programs would require the presense of libraries that otherwise
7857 could be removed from a rescuse diskette.
7859 The ss include files are now installed correctly so they can
7860 actually be used by another package.
7862 If the profiling libraries are built, they are now installed on a
7863 "make install-libs".
7866 E2fsprogs 1.03 (March 27, 1996)
7867 ===============================
7869 Change the m68k bit numbering for bitmasks to match the bit numbering
7870 used by all other ext2 implementations. (This change was requested by
7871 the m68k kernel development team.)
7873 Support (in-development) filesystem format revision which supports
7874 (among other things) dynamically sized inodes.
7876 Fixed a bug in the ext2 library so that an intelligent error is
7877 returned if mke2fs is run with a ridiculously small number of blocks
7880 Fixed a bug in the ext2 library which required that the device be
7881 openable in read/write mode in order to determine its size. This
7882 caused e2fsck -n to require read/write access when it was not
7883 previously necessary.
7885 Fixed a bug in e2fsck which casued it to occasionally fail the test
7886 suite depending on which version of the floating point library it was
7889 Fixed a bug in e2fsck so that it now halts with a fatal error when
7890 certain superblock consistency checks fail. Previously it continued
7891 running e2fsck, with some potential confusing/damaging consequences.
7893 Added new flag to fsck which allows the root to be checked in parallel
7894 with other filesytems. This is not the safest thing in the world to
7895 do, but some system administrators really wanted it.
7897 Fixed -Wall flames in lib/ss.
7900 E2fsprogs 1.02 (January 16, 1996)
7901 =================================
7903 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
7905 Change e2fsck to print statistics of how many non-contiguous files are
7906 on the system. Note that a file which is larger than 8k blocks, it is
7907 guaranteed to be non-contiguous.
7909 In mke2fs, print a warning message if a user tries to format a whole
7910 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
7911 whole disk, the -F (force) option forces mke2fs to format a whole disk
7914 Fix a bug in fsck where in some cases it might start checking
7915 partitions in the next pass before it finishes checking partitions in
7916 the current pass. This still won't cause two partitions on the same
7917 disk will be checked, so it's rarely a problem in real life.
7919 Patch lsattr so that it won't hang when checking a named pipe.
7921 Minor compilation fixes:
7922 * Fix the order of libraries that were linked in debugfs.
7923 * Allow the sources to be compiled with -ansi turned on.
