1 E2fsprogs 1.43.8 (January 1, 2018)
2 ==================================
4 Fix a bug where updated bitmap checks might not be written to disk.
5 (Addresses Debian Bug: #883869)
7 Some newly added fields in the superblocks were not getting byte
8 swapped (which were not noticed since big endian systems are amazingly
9 unpopular). Fix them and compile-time checks to avoid this class of
10 bugs from happening in the future. (Lustre Bug #9309)
12 Fix a potential use after free bug in e2fsck when fixing a corrupted
13 root node in directory hash tree.
15 Fix a bug in e2fsck where a badly/maliciously corrupted superblock
16 (which is not fixed due to the -n option, for example) can cause a
17 floating point exception when printing the summary statistics.
18 (Addresses Debian Bug: #879220)
20 Fix debugfs's ncheck command so that it correctly prints the inode
21 number when printing an error message.
23 Fix a bug in e2freefrag where it could print an incorrect free blocks
24 count on a file system with the 64-bit block number feature.
26 Update the German, Serbian, Spanish, and Ukrainian translations.
28 Fix a bug where resize2fs's free blocks sanity check could fail with a
29 false positive and refuse to check a file system with the 64-bit block
32 Fix and clarify various man pages and documentations. Also fixed up
33 some random usage texts that were incorrect. (Addresses Debian Bugs:
36 Fixed various Debian Packaging Issues. (Addresses Debian Bugs: #880207,
37 #881408, #881590, #881591)
42 Fix various compiler warnings.
44 Clean up Makefile output.
46 Fix compatibility problems with glibc 2.27 casued by a collision with
50 E2fsprogs 1.43.7 (October 16, 2017)
51 ===================================
53 Fix the error handling code in debugfs, fuse2fs and tune2fs so errors
54 trying to replay the journal won't accidentally result in a seg fault
55 if reopening the file system after the journal replay fails for some
58 Fix resize2fs to avoid it from either failing or corrupting the file
59 system image in certain corner cases when doing an off-line resize.
61 Fix many spelling mistakes in various man pages, code comments, and
64 Fix e2fsck and debugfs so that maliciously corrupted file systems will
65 not cause buffer overflows. (Addresses Debian Bugs: #873757, #878104)
67 Update German translation. (Addresses Debian Bug: #833514)
69 Fixed various Debian Packaging Issues. (Addresses Debian Bugs:
70 #873812, #873813, #876551)
75 Test descritions have been shorted to fit in 80 columns.
77 Fix various tests to avoid leaving temp files in /tmp.
80 E2fsprogs 1.43.6 (August 29, 2017)
81 ==================================
83 Fix printing of quota inconsistency messages on 32-bit platforms in
84 e2fsck. Also fix a bug which cause project quota problems to be
85 labelled as group quota problems.
87 Fix UI problems caused by fuzzy translations such that some messages
88 are in English and some are in the foreign language, and it's not
89 obvious to user how to answer yes/no questions. (Addresses Debian
92 Fix some out-of-bounds memory accesses in e2fsck caused by (usually
93 maliciously) corrupted file systems. (Addresses Debian Bugs: #871539,
96 Optimize CPU usage in e2fsck for very large, very fragmented sparse
99 Add an optional mode in e2fsck which trades off additional memory for
100 CPU time when processing file systems that are heavily hard-linked.
101 (This can be a very large amount of memory, so this feature is
102 disabled for now. How to automatically determine when it would be
103 helpful to enable this optimization, and when it is _safe_ to enable
104 this optimization is still a bit of a research problem.)
106 The mke2fs program will automatically upsize the inode size to 256 if
107 it is not explicitly specified on command-line and the default inode
108 size is not large enough to support the project quota feature
109 requested by the user. If the inode size is explicitly specified to
110 be 128 bytes, and the project quota is enabled mke2fs will fail since
111 with an error explaining that project id's can't be supported when the
112 inode size is < 256 bytes.
114 The tune2fs program will not allow the project feature or project
115 quotas to be enabled in the inode size is 128 bytes.
117 The tune2fs program now prints a more understandable message explaining
118 that the file system needs to be checked using e2fsck -f before
119 running certain complex tune2fs operations. (Addresses Debian Bug:
122 If the proceed_delay option is enabled in /etc/e2fsck.conf, the message
123 indicating that user can wait N seconds to proceed was ambiguous.
124 That message has been made more clear. (Addresses Debian Bug:
127 Fix LFS bug which caused e2image to fail to create regular e2image
128 files which are larger than 2 GiB on 32-bit platforms. (Addresses
131 Fix FreeBSD portability problem caused by the fact that they no longer
132 use block devices. (Disks are character mode devices.)
134 Update the Czech, French, Polish, Swedish, and Vietnamese translations.
136 Fixed various Debian Packaging Issues.
142 Avoid changing the blkid cache when running tests. (Normally the
143 blkid cache is not writable by the user running tests, but...)
145 The tar file generation process will now create reproducible
148 Removed legacy entries for ext4dev in the default mke2fs.conf file.
151 E2fsprogs 1.43.5 (August 4, 2017)
152 =================================
154 Fix a bug which could cause e2fsck to loop forever when rebuilding an
155 encrypted directory with entries with identical prefixes up to an
156 embedded NUL character.
158 Fix build when configured with --disable-threads or --enable-profile.
160 Fix ext2fs_sync_device() so it returns the proper error code if the
161 BLKFLSBUF ioctl fails for some reason.
163 Fix a potential crash in tune2fs when enabling project quota when the
164 file system has no inodes by fixing error handling in the
165 quota_write_inode() in libsupport.
167 Fix a bug in debugfs's "ls -p" handling which could cause it to print
168 garbage after a file name in a directory entry.
170 Fix a number of bugs in debugfs, dumpe2fs, e2fsck, tune2fs, and
171 resize2fs where a carefully/maliciously corrupted file systems (found
172 by American Fuzzy Lop) could these programs to crash or hang.
173 (Addresses Debian Bug #868489)
175 E2fsck no longer issues some harmless bitmap warnings caused by a
176 corrupted file system; since those corruptions will be fixed up by
177 e2fsck later, there's no point issuing these internal warnings.
179 E2fsck will now notice invalid quota inode numbers, and offer to fix
182 Fix a regression introduced in e2fsprogs 1.43 which broke mke2fs's
183 hugefile creation so that they aren't contiguous. (Addresses Google
184 Bugs 62791459 and 638037607)
186 Fix how backup superblocks are written in big endian systems so they
187 are all correctly byte swapped.
189 Fixed tune2fs's support for enabling and disabling project quota.
191 The badblock program now properly handles languages which have
192 multi-column wide character such as Chinese. (Addresses Debian Bug:
195 The mke2fs -U option now accepts "null", "clear", "random", or "time"
196 just as tune2fs's -U option.
198 Fix e2fsck's -E bmap2extent feature (which converts a file to use
199 extents from indirect block maps) so that it handles sparse files correctly.
201 Fix libext2fs to correctly handle accounting for an external xattr
202 block on bigalloc file systems.
204 Fix e2fsck to correctly handle quota accounting when deleting files
205 that have multiply-claimed blocks pass 1b.
207 Fix potential buffer overrun bug in e2fsck when using 128 byte inodes.
208 (Addresses Google Bug 37326362).
210 E2fsck's extent tree optimization can now be disabled via an
211 command-line extended option or via an e2fsck.conf configuration
214 The e2fsck program now properly updates the quota accounting when
215 optimizing the extent tree. (Addresses Google Bug 36391645)
217 Fix some error handling in e4crypt when operating on keyring ID's.
219 Fix e2fsck's quota handling when the bigalloc feature is enabled.
221 The libext2fs file system now uses readahead when opening file systems
222 to speed up opening very large file systems with the meta_bg option.
224 If e2fsck logging is enabled, e2fsck will report the exit code in the
225 last line of the log file.
227 Debugfs can now open file systems with a bad superblock checksum, and
228 the show_super_stats command will print the expected checksum.
230 Fix a regression introduced in e2fsprogs 1.43.4 where tune2fs was not
231 able to correctly enable the quota feature. (Addresses Debian Bug
234 E2fsck will only return an exit status code of 1 if it has fixed a
235 file system corruption. If it only performed an optimal optimization
236 of internal file system metadata, it will now return 0.
238 Fix e2fsck so it won't check inode fields of deleted inodes. This was
239 mostly harmless, but the addition of a check in 1.43.4 to enforce the
240 requirement that inline data inodes have a system.data attribute
241 caused a regression in xfstests generic/079. Fix this and a number of
242 other checks which could lead to false positive reports of file system
245 Removed a debugging printf in libsupport which could result to some
246 extraneous and confusing output if the user specifies a quota type.
248 The debugfs logdump command now accepts a new -S option which will
249 cause it to print information about the journal superblock.
251 Added a missing space in debugfs's ls -l output to separate the size
254 Update the Czech, Danish, Dutch, French, Hungarian, Polish, Serbian,
255 Spanish, Swedish, Ukrainian, and Vietnamese translations.
257 Update various man pages. (Addresses Debian Bugs #867895 and #865584)
259 Fix various compiler and UBSAN warnings.
261 Fixed various Debian Packaging Issues. (Addresses Debian Bugs
268 The blkid library can now recognize exfat file systems.
270 Add new test, j_recover_csum3_64bit, which checks to make sure we
271 correctly recovering 64-bit journals using the v3 checksum format.
273 Fix portability assumption in tests; don't depend on the existence of
276 Fix portability with newer versions of glibc and with Cygwin builds on
277 Windows 8 and Windows 10.
279 Clean up the comments in problem.c match the message that will
282 Removed an unused an obsolete header file.
286 E2fsprogs 1.43.4 (January 31, 2017)
287 ===================================
289 Fix e2fsck to require that the system.data extended attribute is
290 always present even for files smaller than 60 bytes, to be consistent
293 Fix a bug which was causing mke2fs -d and fuse2fs to improperly handle
296 Fix a bug which could cause mke2fs -d to fail if there is an
297 zero-length file in source directory tree.
299 Clarify the default for the "proceed?" question printed by mke2fs and
300 tune2fs. (Addresses Debian Bug: #852727)
302 Debugfs will now display project quota information.
304 Debugfs's do_set_xattr now uses C strings to parse extended attribute
305 values, and will print the extended attributes using either C strings
306 or hex bytes when using debugfs's do_get_xattr command. It will now
307 allow developers to see the contents of the system.data extended
310 Fix a bug in mke2fs where I/O errors weren't getting properly reported
313 Fix multiblock writes in the unaligned Direct I/O fallback code.
314 (Which is rarely needed on Linux systems, but which is required on
317 Make sure the default mke2fs.conf file includes the uninit_bg feature
318 flag. (Which was accidentally dropped in v1.43).
320 Fix a bug in resize2fs when operating on very large file systems which
321 have a block size different from the VM page size.
323 If the reported device size is absurdly large, mke2fs will now report
324 an error instead looping forever or crashing.
326 Fix various Coverity warnings and other memory leaks in fuse2fs and
327 extended attribute manipulation functions.
329 Replace a test file but which had a "non-commercial use-only"
330 copyright permission file with a newer version from the Cyrus imapd
331 package which now has a 4-clause BSD license, which was making some
332 lawyers nervous, even though the test file in question was only used
333 in lib/et's regression testing and was never included in any compiled
334 binary. (Addresses Debian Bug: #840733)
336 Stop installing mkfs.ext4dev and fsck.ext4dev
338 Update Chinese, Czech, Polish, Serbian, and Spanish translations and
339 add the Finnish and Malay translation. (Addresses-Debian-Bug: #774379)
341 Update various man pages (Addresses-Debian-Bug: #852726)
346 Fix more FreeBSD-11 compatibility bugs, including some unmasked by
351 Fix build failure on RHEL 5.x systems caused by an old version of
354 Fix a number of bugs reported by ASAN that can cause some (mostly
355 harmless) memory dereferences beyond allocated memory.
358 E2fsprogs 1.43.3 (September 4, 2016)
359 ====================================
361 Fix e2fsck's handling of timestamps on 32-bit systems.
363 E2fsck will now check, and if necessary repair the extra isize fields
364 in the inode and superblock.
366 Fix crashes on architectures such as sparc64 that are sensitive to
367 unaligned pointer dereferences in the journal recovery code when
368 journal checksums are enabled.
373 Support reproducible builds by not capturing the build directory into
374 the mk_cmds and compile_et scripts. Also fix debian build rules to
375 ensure build reproducibility.
377 Fix debian build rules to ensure build reproducibility and to avoid
378 hiding the linker flags for e2fsck.static so the build hardening log
379 scanner can properly audit the build.
381 Fix compatibility with FreeBSD's pmake and teach the configure script
382 to force the creation of pmake-compatible Makefiles if the
383 FORCE_NATIVE_MAKE environment variable is set to a non-empty value.
386 E2fsprogs 1.43.2 (September 1, 2016)
387 ====================================
389 Fix resize2fs so it will not crash if there is an extended attribute
390 block but it doesn't need to migrate any blocks during an off-line
393 Fix a crash when mke2fs or debugfs tries to copy in a directory
394 hierarchy containing an empty directory
396 Mke2fs will now use a larger journal by default for filesystems
397 greater than 128 GB. (1GB instead of 128 MB.)
399 Fix an alignment bug in e2fsck which caused sparc64 architectures to
400 crash when replaying the journal on file systems with a 64-bit block
403 Clarify the message printed by tune2fs message when the user needs to
404 run e2fsck so it's clear that the -f flag to e2fsck is needed to
405 force a full e2fsck scan. (Addresses Debian Bug: #828022)
407 Fix a bug in e2fsck caused by a power failure during e2fsck's journal
408 replay could leave the file system in a state where if the file system
409 is mounted without doing a full e2fsck scan, the file system could get
412 Fix the logic in e2fsck which decides when to repair legacy negative
415 Add a command to debugfs to copy the inode structure from one inode to
418 Fix a typo in debugfs's stat command when printing out the dtime field
419 on file systems with an extended timestamp.
421 Fix big endian bugs in the e2undo program. (Addresses Red Hat Bug
424 Debugfs's logdump can now properly handle journals larger than 2GB.
426 Avoid installing the man page for fuse2fs if it has not been built.
428 Update the Catalan, Chinese, Danish, Dutch, French, German, Polish,
429 Swedish, Ukrainian translations and added new translations for
430 Hungarian and Serbian.
436 Fix portability problems in fuse2fs. Previously it wouldn't build on
437 systems with older glibc versions where clock_gettime() is only
438 available in the librt library, and if libintl is not bundled into the
441 Remove complicated logic which caused a static code analyzer to flag a
442 false positive. (A static code analyzer also found a valid bug in
443 deciding when to repair a legacy negative timestamp encoding, so
444 eliminating false positives is important.)
446 Fixed a bug where the ext2fs library cloud provoke when a
447 extfs2_zero_blocks() is used (via fallocation, initializing a file
448 system, uninitialized uninitialized inode table blocks) after a
449 different file system which also used ext2fs_zero_blocks().
451 Enable the unix_io manager in the ext2fs library so it can accept the
452 use of a file descriptor. This is helpful in cases where the file
453 descriptor comes from temporary file created using O_TMPFILE, or
454 passed in from a unix domain socket.
456 Fix a Windows64 portability bug.
459 E2fsprogs 1.43.1 (June 8, 2016)
460 ===============================
462 Fixed e2fsck so that it would correctly update the project quota usage
463 when deleting a corrupted and inode, and fixed mke2fs so it wouldn't
464 dereference memory beyond the small inode structure (which was wrong,
465 but worked mostly by accident unless hardening or some security malloc
468 Fixed a large number of FreeBSD portability problems. (To build on
469 FreeBSD, however, we still need to use GNU Make and redirect dd to use
472 The configure script now supports --enable-hardening, which enables
473 stack protection, fortify, read-only relocation tables, immediate
474 dynamic symbol binding, and text segment ASLR (if the kernel has
475 userspace ASLR support enabled) by enabling position independent
476 executable code. (Distributions who want to do their own special
477 thing can set CFLAGS, CFLAGS_SHLIB, CLFAGS_STLIB, LDFLAGS,
478 LDFLAGS_SHLIB and LDFLAGS_STATIC as appropriate.)
480 The configure script now supports --disable-tdb since on 64-bit
481 systems, it's much faster to just enable additional swap space. The
482 scratch_files feature in e2fsck.conf is mostly only useful on 32-bit
485 Fixed the Direct I/O fallback codepath in the Unix I/O manager so that
486 read/modify/write worked correctly. Fortunately in practice (with the
487 exception of the Undo handler when running on FreeBSD) used this buggy
488 codepath. so file systems weren't getting corrupted.
490 Mke2fs will now warn if the user provides a label which is too long.
491 (Addresses Debian Bug: #791630)
493 Debugfs's rdump command now works correctly when dumping the root
494 directory of a file system. (Addresses Debian Bug: #766125)
496 Fixed a bug in debugfs so it would correctly calculate a block group's
497 checksum field field on 64-bit systems.
499 E2fsck now has a much more understandable error message when the
500 journal superblock is corrupt and the user declines to fix it.
501 (Addresses Debian Bug: #768162)
503 Fixed support of extended timestamps on 64-bit systems.
505 Updated/fixed various man pages. (Addresses Debian Bugs: #766379,
506 #761144, #770750, #428361, #766127)
508 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #825868)
514 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
516 Fixed Android build makefiles (which was missing a newly added file in
519 In general, checks on s_creator_os have been removed in favor of
520 feature flag specific checks; if there is something that can't be
521 checked via the presence of a feature flag, we will simply check
522 whether the creator OS is *not* EXT2_OS_HURD which is the one
523 operating system where there has been extensive abuse of the
526 The libmagic library has been suppressed when running the regression
527 test suite to avoid false test failures caused by differences between
528 versions of libmagic (and/or the magic number database).
530 The tests/test_script program now accepts the --failed option, which
531 will run those tests that had previously failed.
533 Fixed tests build on those systems which require LDFLAGS to be set.
535 Fixed the regression test suite so it will properly filter out version
536 numbers with two components (such as 1.43) from log files before
537 comparing them with the expected golden output.
540 E2fsprogs 1.43 (May 17, 2016)
541 =============================
543 Add support for the ext4 metadata checksum, checksum seed, inline
544 data, encryption, project quota, and read-only features.
546 Support for the very old, experimental, and never-added-to-mainline
547 compression feature has been removed.
549 Mke2fs will now create file systems with the metadata_csum and 64bit
550 features enabled by default.
552 The mke2fs program will now support multiple -O options (instead of
553 just ignoring all but the last -O option).
555 Mke2fs will now correctly determine the size of a file system and
556 handle the discard operation correctly when the "-E offset=NNN" is
557 used. (Addresses Debian Bug: #803629)
559 The tune2fs program will ask the user for confirmation before starting
560 dangerous operations if the terminal is available, and it will replay
561 the journal if necessary.
563 Add an ext2/3/4 FUSE server
565 Debugfs can now modify extended attributes and journal transactions.
567 Debugfs now can properly display and set extended timestamps.
569 E2fsck will offer to fix extended timestamps that were incorrectly
570 encoded by older kernels.
572 Fix miscellaneous MMP bugs in debugfs.
574 Fix sparse_super2 bugs in mke2fs and resize2fs.
576 Fix or improve offset support in mke2fs, e2undo, and libext2fs.
578 The resize2fs command can now convert file systems between 64-bit and
581 Fix potential out-of-bounds memory access in resize2fs when doing a
582 large off-line file system grow operation.
584 We now use a new e2undo file format which is much more efficient and
585 faster than the old tdb-based scheme. Since it so much faster,
586 e2fsck, tune2fs, debugfs, and resize2fs now also can support using
587 creating an undo file.
589 The mke2fs command can now set the error behavior when initializing
590 the file system (so the administrator doesn't have to issue a separate
593 Teach mke2fs to parse a human-readable argument for -i option.
595 Teach mke2fs to automatically handle creating file systems > 500T by
596 automatically enable the meta_bg feature.
598 Mke2fs will now prompt for user verification before rewriting a file
599 system's superblock using the -S option.
601 Mke2fs no longer complains if the user tries to create a file system
602 using the entire block device (e.g., without using a partition). The
603 minor number convention is not used by all block devices, and it's
604 quite normal in some circumstances to create a file system on /dev/sdc
605 instead of /dev/sdc1.
607 Fix an "mke2fs -d" bug which could create inodes with invalid
608 extended attribute blocks
610 E2fsck is now much more paranoid about not freeing or corrupting
611 critical metadata blocks, such as inode table blocks, even if
612 corrupted indirect blocks or extent trees point at these blocks.
614 E2fsck now prints block ranges in pass1b instead of listing all of the
617 E2fsck will try to expand the root directory if the lost+found can't
618 be linked to the root directory. Also, offer to use the root
619 directory if lost+found can't be created.
621 E2fsck is now more paranoid handling corrupted extent trees as well as
624 E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
625 to recover from a corrupted extent tree, or (c) to convert
626 block-mapped inodes to use extents.
628 E2fsck now has a readahead mechanism which can significantly speed its
629 performance, especially on RAID arrays.
631 E2fsck now has a "yes to all" option which the user can give if she is
632 tired of answering 'y' to a very large number of questions.
634 E2fsck will now ignore the badblocks inode if the contents of the
635 badblocks inode indicate that the portion inode table containing the
636 badblocks inode is bad. (We must go deeper...)
638 E2fsck can now correctly fix directory with holes on bigalloc file
641 E2fsck will now check for extent mapped inodes with no extent header
642 and clear them if found.
644 E2fsck now checks to make sure the extended attribute header doesn't
645 result in the xattr extending beyond the bounds of the inode
647 Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
648 revoke records if the journal is corrupted.
650 Fixed a bug in e2fsck which could cause it loop forever if a special
651 inode has too many invalid block mappings.
653 Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
654 confused if an attempt to allocate a block can't find any free space
657 E2fsck will no longer try to force rewrite blocks located beyond the
660 The e2fsck program will no longer update the quota inodes when it is
663 Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
664 extent-mapped directory.
666 Fixed a bug in resize2fs which could lead to resize2fs crashing or a
667 corrupted file system if the file system is almost completely full
668 when trying grow a file system and we need to allocate blocks to grow
669 the block group descriptors.
671 Fixed a bug in resize2fs which could cause it to get fooled trying to
672 determine the RAID array's stride when flex_bg is enabled.
674 Fix resize2fs bug that could leave block allocation bitmaps
677 The dumpe2fs output has been improved so it is cleaner and always fits
678 within 80 columns. Also added a more easily machine-parsable output
681 The mke2fs program can now pre-populate a file system from a directory
682 hierarchy using the -d option.
684 The mke2fs program now skips zeroing inode table blocks if they were
685 already zeroed using the discard feature.
687 Check to make sure file system features which can not be supported by
688 HURD are not enabled if the file system is created to be
691 Added a new e2fuzz command that will fuzz an ext4 image for testing
694 The debugfs logdump command can now deal with 64-bit revoke tables
695 correctly. Also, "logdump -O" will print the old log contents (before
696 the journal was replayed).
698 The debugfs bmap command can now be used to set or allocate a physical
701 Fixed a bug so "filefrag -B -e -v" does not return a separate entry
704 The filefrag program now accounts for holes in sparse files created by
705 the file punch operation as an expected/optimal mapping.
707 The file I/O functions now correctly handle inodes containing
708 uninitialized blocks.
710 Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
711 file system won't result in corrupted block bitmaps.
713 Updated/fixed various man pages. (Addresses Debian Bug: #798425)
719 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
721 Added Android build files so that e2fsprogs can be built in the
724 Reduce the use of libc functions in libext2fs that may not be present
725 in the boot loader environment, at least for those functions that are
726 needed by boot loaders such as yaboot.
728 Developers can now override the debugging and optimization flags by
729 redefining the CFLAGS makefile macro.
731 The libext2fs library now has support for fallocate.
733 The mke2fs command will now ask the user for confirmation if block
734 device or image file contains an existing file system image, and
735 stdout and stdin are connected to a tty.
737 The libext2fs library now picks a more intelligent goal block when
738 doing block allocations.
740 The libext2fs library will now automatically set the BLOCK_UNINT flag
741 if all of the blocks in a block group are free, to speed up future
742 e2fsck and dumpe2fs operations on the file system.
744 Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
747 The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
750 The ext2fs_bmap() function supports new flags BMAP_UNINIT and
753 The ext2fs_new_block2() function will now call the alloc_block hook
754 before checking fs->block_map.
756 Support for the MMP feature can now be disabled at compile time.
758 Added support to manipulate extended attributes to libext2fs.
760 Added a lot of new regression tests.
762 Added endian annotations so it's possible to scan e2fsprogs for endian
763 problems using a static code analyzer.
765 Fixed memory leaks in libext2fs.
767 The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
768 There is now a script in the contrib directory which automates most of
771 The build system will now run cppcheck (a static code analysis tool)
775 E2fsprogs 1.42.13 (May 17, 2015)
776 ================================
778 Fixed a potential buffer overflow while closing a file system in
779 libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
781 Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
782 (Addresses Debian Bug: #760275)
784 Fixed a deadlock which occurs when using systemd and e2fsck.conf's
785 logging feature. (Addresses Debian Bug: #775234)
787 Fixed a bug which could cause programs using libext2's inode table
788 scanning functions from crashing on certain corrupted file systems.
789 (Addresses Debian Bug: #773795)
791 Fixed dumpe2fs so it won't crash if the user doesn't specify a block
792 device (file system). (Addresses Debian Bug: #764293)
794 Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
795 will report the correct directory inode containing the inconsistency.
797 If e2fsck fails to grow the dir_info structure due realloc(3) not
798 having enough memory, it will now fail with explanatory message
799 instead of staggering on failing with a confusing internal error
802 The tune2fs program will zero out the superblock journal backup
803 information when removing a journal from a file system.
805 The mke2fs program now enables the large_file feature by default.
807 Fixed a bug which could cause badblocks to crash if there are millions
808 and millions of bad blocks.
810 Fixed some use-after-free bug in resize2fs and e2fsck.
812 Fixed a memory leak in tune2fs.
814 Fixed some bigendian bugs that had crept into both indirect and extent
815 handling inside libext2fs.
817 Updated/fixed various man pages.
819 Update Esperanto, German, and Spanish translations. Added Danish
825 Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
827 Clean up some build system problems (build failures with various
828 configure options, fix Posix portability issues, etc.)
830 The functions ext2fs_inode_alloc_stats[2]() and
831 ext2fs_block_alloc_stats[2]() now check the inode and block numbers
832 passed to them, to avoid crashes caused by buggy callers.
834 The libext2fs directory iterator will now check for an invalid
835 directory entry length instead of possibly walking off the end of the
839 E2fsprogs 1.42.12 (August 25, 2014)
840 ===================================
842 Fix various e2fsck bugs when trying to repair bigalloc file systems.
844 E2fsck can now repair a file system with an overly large
845 s_first_meta_bg field, which had previously caused all e2fsprogs
846 programs to crash when trying to open such a file system.
848 Fix e2fsck so that it can correctly fix a number of rare file system
849 corruptions that were discovered when using a file system fuzzer.
851 Fix e2fsck so it does not try to write back block group descriptors if
852 they have not been modified.
854 Mke2fs program will now place metadata blocks in the last flex_bg so
855 they are contiguous. This reduces free space fragmentation in a
856 freshly created file system, as well as allowing mke2fs commands which
857 request extremely large flex_bg size to succeed.
859 Mke2fs now creates hugefiles more efficiently (with fewer extent tree
862 Fix a 32/64-bit overflow bug that could cause resize2fs to loop
863 forever. (Addresses-Launchpad-Bug: #1321958)
865 The resize2fs program will now use much less memory when resizing very
868 Fix a bug which could cause resize2fs to get confused and produce a
869 corrupted file system when shrinking a file system that had been
870 previously expanded and converted to use the meta_bg file system
871 format, but which no longer needs to use the meta_bg file system
872 format any longer. This typically happened with large (> 16TB) file
873 systems. (Addresses Debian Bug: #756922)
875 The e4defrag program will now defrag backwards-allocated files.
877 Fix tune2fs updating UUID's when manipulating file systems with
878 external journals (both the file system and journal UUID).
880 Fix tune2fs so it can remove an external journal for file systems with
883 Add a new debugfs command, "inode_dump", which prints the inode in hex
886 The debugfs's "set_inode_field" will now automatically allocate blocks
887 for indirect blocks and extent tree blocks.
889 Fix debugfs's "set_inode_field" so can properly handle
890 "block[IND|DIND|TIND]".
892 The debugfs "rdump" command will now take multiple source arguments.
894 Fixed a double close(2) bug in "rdump" and "rdump -p".
896 Fix debugfs's argument parsing for the freefrag command.
898 Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
899 (Addresses Launchpad Bug: #1356496)
901 Clarified messages that were confusing users in debugfs, e2fsck,
902 mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
905 Dumpe2fs will now complain if extra arguments are given to it.
906 (Addresses Debian Bug: #758074)
908 Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
910 Update Czech, Dutch, French, Polish, Spanish, Swedish, Ukrainian, and
911 Vietnamese translations.
916 The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
917 number of system calls issued.
919 Fixed profiled build.
921 The libext2fs library will now more efficiently split an extent tree
922 index block when appending to an end of a file.
924 Fixed free block accounting for 64-bit file systems.
926 Add a new function ext2s_inode_size_set() which takes care of all of
927 the required feature flag modifications.
929 The regression tests no longer require the presence of the md5sum
932 Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
935 Fix various Coverity warnings (#1225003, #1229243, #1252003)
938 E2fsprogs 1.42.11 (July 9, 2014)
939 ================================
941 Add support so that mke2fs can create hugefiles so that they are
942 aligned relative to the beginning of the disk, instead of relative to
943 the beginning of the partition, using the mke2fs.conf configuration
944 parameter "hugefiles_align_disk".
946 Fix a bug which causes e2fsck to abort a journal replay on a file
947 system with bigalloc enabled. (Addresses Debian Bug: #744953)
949 Add sanity checks so that mke2fs will refuse insanely large flex_bg
950 counts specified by the -G option. Insanely large flex_bg sizes can
951 result in a file system which can't be unmounted, or with extremely
952 pessimal metadata layouts.
954 The mke2fs program will provide a better metadata layout for
955 moderately large (but believable) flex_bg counts, such as 133,072.
957 The mke2fs program will also check the kernel version number to
958 determine whether the lazy_itable_init option is supported, so that
959 lazy inode table initialization can be used even if the ext4 is
960 compiled as a module which isn't loaded at the time that mke2fs is
963 Add description of ext4's mount options to the ext4 section 5 man
966 Improve the chattr man page and clean up the chattr usage message.
968 E2fsck will now automatically fix a last mount time or last write time
969 which is in the future in preen mode, instead of aborting the fsck
972 Mke2fs will now check the file system revision number requested by the
973 command line, and reject it if it is too large. A file system with an
974 unsupported revision number will not be accepted by any of the other
975 file system tools, and this command line option is rarely used, so
976 let's try to help the user not shoot their own foot off.
978 The debugfs program can now set the error count and associated
979 first_error and last_error fields in the superblock using the
980 set_super_value command.
982 Resize2fs will not try to calculate the minimum size of a file system
983 if it contains errors. Otherwise a very badly corrupted file system
984 image can cause the minimum size calculation to loop forever. Since
985 resize2fs will not allow a file system marked as containing errors to
986 be resized. It's pointless to calculate the minimum size, so just
989 Fixed a typo in one of mke2fs's error message.
991 If filefrag runs into an error, it will continue processing the rest
992 of the files specified on the command line, but then exit with an
995 Filefrag now prints some additional new flags (such as
996 FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
998 Fixed support in filefrag for files with > 2**32 blocks on 32-bit
1001 Fixed a file descriptor leak in debugfs when copying files.
1003 Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
1004 to create file systems larger than 2GB on 32-bit platforms.
1005 (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
1007 Add Esperanto and Ukrainian translations, and update Czech, Dutch,
1008 French, German, Italian, Polish, Swedish, and Vietnamese
1011 Fixed various compiler warnings.
1017 The gcc "-checker" option has been long deprecated, so remove support
1018 from e2fsprogs. It was causing a few people to be confused when they
1019 tried enabling the configure option.
1021 Update to the latest version of the config.status and config.rpath
1022 files, as well as newer versions of the autoconf files in aclocal.m4.
1023 Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
1024 people who want to use autoreconf to do so.
1026 Make the use of strptime() function in debugfs to be more portable to
1027 fix regression test failures for FreeBSD and MacOS.
1029 A few miscellaneous changes designed to make life easier for
1032 Fix the f_quota test and some Makefile dependencies if quota support
1035 Fix cross-compilation support, which got broken in 1.42.10.
1036 (Addresses Debian Bug: #753375)
1038 Delete lib/ext2_types.h on a make clean, and build it as necessary.
1040 Add a debug program used for libext2fs unit tests.
1042 Clean up the tests so that it avoids using GNU-specific behaviour in
1043 mktemp. Make sure the temporary files are cleaned up if the tests are
1046 Add a new ext2fs_close_free() helper function which automatically
1047 takes care of freeing the ext2_filsys structure even if ext2fs_close()
1051 E2fsprogs 1.42.10 (May 18, 2014)
1052 ================================
1054 Mke2fs now creates file systems in regular files (which is very often
1055 used when maintaining virtual machine images) without requiring the
1056 user to use the force option. In addition, the mke2fs output has been
1057 made much less verbose and only displays information that users will
1058 be more likely to find useful by default.
1060 Mke2fs now will ask the user to confirm that they want to continue
1061 before wiping out a pre-existing file system, partition table, or LVM
1064 Mke2fs now has the ability to create file systems where all the
1065 metadata is located at the very beginning of the device. This can be
1066 useful for flash devices which have SLC flash at the beginning of the
1067 disk, for FAT compatibility, for example. As part of this, mke2fs and
1068 tune2fs can control the location of the data blocks used by the
1069 journal inode. In addition, the new sparse_super2 feature allows for
1070 even fewer (anywhere from zero to two) backup superblocks.
1072 Mke2fs now uses much less CPU when allocating the blocks used for very
1075 Mke2fs can now support creating a file system at an offset. This can
1076 be useful when creating a disk image for virtual machines (Addresses
1077 Debian Bug: #497984)
1079 Previously, e2fsck had a number of very serious bugs when checking a
1080 file system which used the new the quota file system option (where the
1081 quota inodes were stored in hidden inodes) and the quota inode was
1082 inconsistent with the actual usage data. This problem was documented
1083 in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
1084 been fixed in 1.42.10, so the quota should be safe to use with
1087 Fixed in a bug in resize2fs which could cause shrink operation fail in
1088 the unlikely situation when the inode table needs to be moved to a
1089 location before the current location.
1091 Resize2fs now has a much more accurate (and less conservative)
1092 estimation of how far the file system can be shrunk. This allows a
1093 mostly empty filesystem which is a few terabytes, to be shrunk to a
1094 few megabytes in a single resize2fs -M operation.
1096 E2fsck will now force a full file system check if there are any file
1097 system inconsistencies detected in the super block.
1099 The filefrag program will now display the shared extent flag, which is
1100 used by file systems such as btrfs.
1102 If the number of inodes in the file systems is larger than the time
1103 that file system was created (as measured by the number of seconds
1104 since January 1, 1970) e2fsck would print a scary (but otherwise
1105 harmless) warning of file system corruption for each inode in the
1106 orphan list. This false positive has been fixed.
1108 The e4defrag program has been fixed so it will no longer refuse with
1109 filesystem with the 64-bit or the bigalloc feature enabled.
1111 The logsave program will print a much less scary message which could
1112 lead users to believe something has gone very wrong with e2fsck exits
1113 with a non-zero exit status (since this is normal after e2fsck has
1114 automatically fixed a file system corruption during a preen
1115 operation). (Addresses Debian Bug: #468821)
1117 When creating a file system which is larger than 16TB, the
1118 resize_inode option must be disabled -- since the resize_inode simply
1119 doesn't support reserving metadata block numbers which is larger than
1120 32 bits. The mke2fs program does this automatically if the file
1121 system size is determined automatically. It will now also do this if
1122 the file size is specified explicitly.
1124 Fixed bugs associated with resize2fs and shrinking bigalloc file
1127 The e2fsck program will no longer try to add a UUID on a mounted file
1128 system with checksums enabled, since this could leave the file system
1131 Tune2fs will allow the removal of an external journal from file system
1132 which is marked as needing the journal replayed when the force ("-f")
1133 option is given twice. (Addresses Debian Bug: #559301)
1135 Tune2fs will no longer support enabling sparse_super if the meta_bg
1136 file system feature is enabled, since it could result in data loss.
1137 In practice, all modern file systems have sparse_super is enabled, so
1138 it's not worth trying to change how tune2fs handles enabling the
1139 sparse_super feature.
1141 Fixed support for 1k block file systems with the meta_bg feature.
1143 When the superblock is corrupt, e2fsck can't figure out the location
1144 of the alternate superblock. Unfortunately, the routine that
1145 calculates the location of the alternate superblock uses 8193 if it
1146 can't figure this out, so the message printed by e2fsck always
1147 suggests using "e2fsck -b 8193". This message has been fixed to
1148 suggest both the superblock location of 8193 and and 32768.
1149 (Addresses Debian Bug: #719185)
1151 The lookback mount detection code that was introduced in 1.42.9 wasn't
1152 actually compiled in due to an autoconf oops, so it's fixed now in
1153 1.42.10. (Addresses Debian Bug: #497984)
1155 A bug introduced in 1.42.9 would cause debugfs to print two error
1156 messages if it found an error while parsing a user-supplied block
1157 number. This has been fixed in 1.42.10.
1159 Update Czech, Dutch, French, German, Polish, Spanish, Swedish, and
1160 Vietnamese translations. (Addresses Debian Bug: #703048)
1162 Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
1165 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
1171 Fixed a lot of coverity, sparse, gcc -Wall, and clang warnings/nits.
1173 Allow the location of pkg-config files to be specified independent of
1174 the libdir location via a makefile variable.
1176 Fixed parse-types.sh not to complain when cross-compiling and the
1177 sizes of types are different between the target architecture and the
1178 architecture of the build system
1180 Allow the regression test suite to work correctly on systems which do
1181 not have the "truncate" or "mksawp" programs.
1183 Allow e2fsck to build correctly on systems (such as Android) that do
1184 not have the signal.h file.
1186 E2fsprogs now has code coverage testing which can be enabled using
1187 "configure --enable-gcov".
1189 The libe2p.h header file can now be used included by C++ programs.
1191 The profile/config file used by e2fsck and mke2fs will interpret
1192 numbers with a leading 0 character to mean that they should be
1193 interpreted as an octal integer.
1195 The extent handling functions in libext2fs have been improved so they
1196 have proper rollback when there is an error splitting an extent. Also
1197 fix a number of bugs when punching holes in files, and fix an
1198 off-by-one bug when inserting an extent into an empty inode.
1200 The libext2fs library now handles the support of BLOCK_UNINIT by
1201 clearing the portion of block bitmap when it is loaded, instead of
1202 when it is used. This reduces the chances of bugs, and and simplifies
1203 the code. It also means that debugfs will properly show that blocks
1204 in uninitialized block groups as being unused when using the testb
1207 The e4defrag program will try to use fadvise64 or posix_fadvise64() if
1208 it is present, which allows 64-bit offsets on 32-bit systems.
1211 E2fsprogs 1.42.9 (December 28, 2013)
1212 ====================================
1214 Mke2fs will detect an attempt to create a file system on a loop
1215 mounted file and complain without the -FF option. Also fixed mke2fs
1216 so it allows the creation of a file system on a mounted device with
1217 two -F options, as documented in the man page, instead of three -F
1220 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
1221 libext2fs to correctly handle bigalloc and 64-bit file systems. There
1222 were many corner cases that had not been noticed in previous uses of
1223 these file systems, since they are not as common. Some of the bugs
1224 could cause file system corruption or data loss, so users of 64-bit or
1225 bigalloc file systems are strongly urged to upgrade to e2fsprogs
1228 The tune2fs program will now not allow changing the uuid on a mounted
1229 file system which has the uninit_bg feature enabled. This avoids a
1230 nasty race where the kernel and tune2fs are both retrying rewrite the
1231 group descriptors at the same time, with different ideas about what
1234 When e2fsck is rehashing an extent-mapped directory, it's possible
1235 (although very rare) that an extent block will need to be allocated;
1236 fix e2fsck to make sure that the block gets marked as used.
1238 Mke2fs will now properly set the LARGE_FILE feature when creating a
1239 journal >= 2GB --- which can happen when using 64k block size.
1241 Fixed debugfs so that its freei command will correctly handle a request
1242 to free a range of consecutive inodes.
1244 Fixed 2fsck so it will not erroneously complain that an external journal
1245 is invalid if it is exactly 2**32 blocks.
1247 Fixed e2fsck so it won't try checking for, and adding, a missing
1248 lost+found directory when running in read-only mode.
1250 Fixed e2image so that progress information won't get leaked to stdout.
1251 (Addresses Red Hat Bugzilla: #1327329)
1253 Fixed e2image to avoid some buffer overruns which would cause it to when
1254 creating a "standard (non-raw, non-qcow2) image file. Standard
1255 e2image files are actually very rarely used, so we didn't notice when
1256 the changes to enable the qcow2 format broke this e2image mode.
1258 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
1259 on the resize_inode feature when the meta_bg feature is set, since
1260 these two features can not be set at the same time.
1262 Fixed tune2fs so that when it disables the quota feature, it updates all
1263 of the backup superblocks.
1265 Fixed dumpe2fs that would cause it to abort when run using an image file
1266 when trying to print the journal information (which is not present in
1267 an e2image created image file).
1269 Fixed a potential integer overflow in e2reefrag.
1270 (Addresses-Debian-Bug: #718205)
1272 Enhance debugfs so that when copying a sparse file from a native file
1273 system into the file system image using the "write" command, it will
1274 create a sparse file into the destination file system.
1276 Enhanced debugfs so it can support a command line which is up to 8k
1279 E2image will refuse (unless the -f option is specified to force the
1280 issue) to create a raw or qcow image using a mounted file system,
1281 unless the -f option is specified to force the issue.
1283 E2image has been optimized for using it to efficiently copy a file
1284 system by only copying the allocated blocks, by using the options -ra.
1285 New options (-o and -O) have been added so that a source and
1286 destination offset can be given. The -p option will print progress
1287 information so the user will know how far along the copy is going.
1288 And finally, the new option -c is useful for updating a file system on
1289 an SSD, by avoiding unnecessary writes. E2image can also shift a file
1290 system image by doing an in place move.
1292 Fix a regression introduced in 1.42.8 which would cause e2fsck to
1293 erroneously report uninitialized extents past the EOF (as determined by
1294 i_size) to be invalid.
1296 Fixed resize2fs so under a corner case when an inode has a complex
1297 extent tree, it will not corrupt an interior node in the extent tree.
1299 Fixed resize2fs which would sometimes corrupt a file system when
1300 shrinking a file system to a minimum size using resize2fs -M.
1301 (Addresses Debian Bug: #660793)
1303 Fixed resize2fs so that it will relocate inode table blocks if this
1304 becomes necessary when shrinking the file system.
1306 Fixed resize2fs and e2fsck so they will not crash when hit a failure
1307 while operating on a file system with the MMP feature enabled.
1309 Fixed a bug in debugfs which caused it create an invalid inode when
1310 trying to write a zero-length file.
1312 E2fsck will no longer crash if it tries to delete an invalid
1313 extent-mapped symlink.
1315 E2fsck will no longer crash if it comes across an directory which is
1316 larger than 2GB (which is not allowed in valid file systems).
1318 Fixed debugfs's help texts to fully document all options and otherwise
1321 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
1324 Fixed various Debian Packaging Issues (#698879, #721365)
1330 Fix sparse, gcc -Wall and clang nits.
1332 Update config.{guess,sub} to the latest version
1334 Fixed various memory and file descriptor leaks on various error paths,
1335 as well as some missing error return checks, which were found using
1338 Run sparse against source files when building e2fsprogs with 'make
1339 C=1'. If instead C=2, it configures basic ext2 types for bitwise
1340 checking with sparse, which can help find the (many many) spots where
1341 conversion errors are (possibly) happening.
1343 Allow the regression test to be run in chrooted environments where
1344 /etc/mtab might be missing.
1346 The ext2fs_punch() function, which was introduced in 1.42, was broken
1347 in many ways, but this was never noticed since it wasn't used for
1348 anything significant. Some of the bugs include failing when trying to
1349 punch a completely sparse file, failing when punching an extent-mapped
1350 inode when the starting block was at the beginning of the inode, and
1351 not being able to punch a single block (where start_blk == end_block).
1352 It also didn't handle being passed an invalid, too-large ending block
1353 number, and didn't handle properly terminate at the right place when
1354 operating on an indirect-mapped inode.
1356 Fixed some minor typo's in the error catalog for libext2fs.
1358 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
1359 setting the file size, to zero the rest of the block to the end of the
1360 file, so that if an ext4 FUSE driver tries to extended the file, that
1361 we don't avoid stale data from being returned.
1363 Fixed ext2fs_bmap() to disallow clients from trying to map or set
1364 logical blocks which are larger than what an extent-mapped or indirect
1365 block-mapped inode can allow.
1367 If debugfs (or some userspace program using libext2fs) creates a file
1368 which is larger than 2GB, make sure the large_file feature flag gets
1371 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
1372 directory which are large enough, the directory entry could get
1373 inserted more than once in the directory.
1375 If quota support is disabled (which is the default), make sure that
1376 all traces of the quota support is removed from usage messages, man
1377 pages, and tune2fs must not be able to enable the quota file system
1378 feature. (Addresses Red Hat Bugzilla: #1010709)
1380 The ext2fs_file_write() now updates i_size on a successful write,
1381 instead of only updating i_size wen the file is closed via
1382 ext2fs_file_close().
1384 Added a shell script, populate-extfs.sh which uses debugfs to populate
1385 an ext2/3/4 file system image from a given directory. It is similar
1386 to the genext2fs program, but it supports ext3 and ext4 file system.
1388 Add changes to the libext2fs library to support block group
1389 descriptors larger than 64 bytes (for future compatibility).
1391 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
1392 leave an extra block in the file when truncating the file down to
1395 The html version info pages are now built using makeinfo --html
1396 instead of the unmaintained and now-obsolete texi2html program.
1399 E2fsprogs 1.42.8 (June 20, 2013)
1400 ================================
1402 As a part of mke2fs's option parsing cleanup, the use of the -R option
1403 will give a warning that it is deprecated (it has been so documented
1404 since 2005) and -E should be used instead.
1406 Mke2fs will not give warnings about the bigalloc and quota options in
1409 If an invalid journal size is given to mke2fs, it will now complain
1412 Debugfs was erroneously giving spurious error messages for certain
1413 extent_inode subcommands which take arguments (split_node,
1414 replace_node, and insert_node). This has been fixed.
1416 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
1417 other programs is used by mke2fs.
1419 Change mke2fs so that it does not set the root directory to the real
1420 uid/gid of the mke2fs process. Add the extended option root_owner to
1421 override this behavior.
1423 Fix resize2fs when shrinking file systems to make sure that bitmap
1424 blocks aren't left outside the bounds of the shrunken file system.
1425 This could happen with flex_bg file systems that were grown using
1426 the old online resizing algorithm.
1428 E2fsck will now detect and repair corrupted extent trees which contain
1429 invalid extents at the end of the extent tree leaf block.
1431 E2fsck will now longer complain about zero length extended attribute
1434 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
1437 Add safety check so tune2fs will not attempt to set the inode size to
1438 be larger than the block size.
1440 Fix e2fsck so it can check a read-only root file system with an
1441 external journal. (Addresses Debian Bug: #707030
1443 Fix off-line resizing of file systems with flex_bg && !resize_inode
1444 (Addresses Debian Bug: #696746)
1446 Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
1449 Enhance chattr to allow clearing the extent flag if the kernel allows
1450 migrating extent based files to use indirect blocks.
1452 Update German translation.
1454 Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
1457 Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
1462 Use secure_getenv() in preference to __secure_getenv().
1464 Optimize CPU utilization of ext2fs_bg_has_super().
1466 Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
1467 SEEK_CUR is used with large files.
1469 The ext2fs_read_inode_full() function will no longer use
1470 fs->read_inode() if the caller has requested more than the base 128
1471 byte inode structure and the inode size is greater than 128 bytes.
1473 Fix build failure with --enable-jbd-debug.
1475 Clean up filtering of outputs for the regression tests by using a
1478 Fix gcc -Wall and clang nits.
1481 E2fsprogs 1.42.7 (January 21, 2013)
1482 ===================================
1484 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
1485 quota features are still under development. For more information
1487 * https://ext4.wiki.kernel.org/index.php/Bigalloc
1488 * https://ext4.wiki.kernel.org/index.php/Quota
1490 Add some new options to filefrag from Lustre's patches to e2fsprogs:
1491 * add -k option to print extents in kB-sized units (like df -k)
1492 * add -b {blocksize} to print extents in blocksize units
1493 * add -e option to print extent format, even when FIBMAP is used
1494 * add -X option to print extents in hexadecimal format
1496 Fix resize2fs so that it can handle off-line resizes of file systems
1497 with the flex_bg feature but without a resize_inode (or if we run out
1498 of reserved gdt blocks). This also fixes a problem where if the user
1499 creates a filesystem with a restricted number of reserved gdt blocks,
1500 an off-line resize which grows the file system could potentially
1501 result in file system corruption.
1503 Fix a resize2fs bug which could cause it to corrupt bigalloc file
1504 systems when doing an off-line resize.
1506 Further optimize resize2fs so it doesn't use quite as much CPU when
1507 resizing very large file systems.
1509 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
1510 possibly corrupt the file system while resizing 64-bit file systems.
1512 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
1513 mke2fs crash due to a divide-by-zero if the 64bit file system feature
1516 Add better error checking to mke2fs to check for invalid parameters
1517 when creating bigalloc file system.
1519 When creating bigalloc filesystems, the -g option to mke2fs will now
1520 specify the number of clusters per block group.
1522 Add to debugfs the functionality to corrupt a specific file system
1523 block via the "zap_block" command.
1525 Add to debugfs the functionality to print out a hex dump of a block in
1526 the file system via the "block_dump" command.
1528 Add to debugfs the functionality to manipulate the extent tree
1529 directly via the "extent_open" command.
1531 Fixed debugfs's mknod command so that it updates the block group
1534 Fix e2fsck so it can detect and fix inconsistencies in the interior
1535 nodes of an inode's extent tree.
1537 Fix a potential memory corruption failure in e2fsck's error path if
1538 the call to ext2fs_open2() fails.
1540 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
1541 resulting file name for the log file is longer than 100 bytes, that it
1542 properly handles this situation instead of crashing.
1544 E2fsck will now report the amount of memory that it attempted to
1545 allocate when a memory allocation request fails, to make it easier to
1546 track down the problem.
1548 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
1549 Lustre Bug: LU-1888)
1551 E2image can now include all data blocks in the e2image output file
1552 when the user specifies the -a option.
1554 If e2fsprogs is compiled without --enable-quota, make sure that
1555 tune2fs can not turn on the feature for new-style quota support, since
1556 afterwards, none of the e2fsprogs tools will be willing to touch that
1559 Optimize e2fsck's so that it uses much less CPU for large file
1560 systems. This can result in significant speedups, especially on
1561 CPU-constrained systems. This was primarily done by optimizing
1562 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
1564 Fix debugfs's htree command so that all its messages are sent through
1567 Fixed debugfs's "dump_file" and "cat" functions work correctly
1568 on file systems whose block size is greater than 8k.
1570 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
1571 less memory. (Addresses Google Bug: 7269948)
1573 Update the spd_readdir.c file in the contrib directory to include some
1574 additions which were made in 2008 that didn't get folded into the
1575 version which we checked into the e2fsprogs source tree. These
1576 enhancements include thread safety, support for readdir64_r(), and
1577 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
1579 Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
1582 Add a command to debugfs to create symlinks.
1584 Document the bigalloc feature in the mke2fs man page. (Addresses
1585 Debian Bug: #669730)
1593 Fix a spelling typo in the libext2fs texinfo documentation.
1595 Change the output from "make check" so that tools such as emacs's "M-x
1596 compile" does not mistake the output as containing a compiler error.
1598 Export two new functions from libext2fs: ext2fs_extent_node_split()
1599 and ext2fs_extent_goto2().
1601 The ext2fs_extents_fix_parents() was fixed so it does not modify the
1602 location of the extent handle if its current location is at an
1603 interior node, rather than a leaf node of an inode's extent tree.
1605 Add a regression test to assure that e2fsck can correctly fix an
1606 inconsistent interior node in an inode's extent tree.
1608 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
1609 correctly support bigalloc file systems which use store block usage
1610 information in units of clusters.
1612 Fixed the help text in the configure script for --enable-quota.
1614 The m68k-specific bitops code has been removed since they were
1615 incorrectly treating bit numbers with the high bit set as signed
1616 integers. Furthermore, modern compilers do a good enough job
1617 optimizing the generic code there is no point in having the m68k
1618 specific asm statements.
1620 Fixed how we link the test programs so they always use the static
1621 libraries, so that we test using the libraries which we have just
1624 Update config.guess and config.sub to the latest versions from the GNU
1627 Fixed the com_err.texinfo file so that it can produce a valid
1628 postscript/pdf printed output.
1630 Add a regression test which checks debugfs's ability to create
1631 symlinks, named FIFO's, and device nodes.
1633 Add a function ext2fs_symlink(), which creates symlinks to the
1636 Add debugging code so we can test old kernel interfaces for online
1637 resize to resize2fs. This backwards compatibility checking is keyed
1638 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
1639 test the functionality of the kernel's older resize ioctls without
1640 needing to install an old version of resize2fs, and to also test a
1641 modern resize2fs's ability to work with older kernels without having
1642 to install an older version of the kernel.
1645 E2fsprogs 1.42.6 (September 21, 2012)
1646 =====================================
1648 When mke2fs creates file systems with lazy itable initialization, the
1649 progress updates for writing the inode table happens so quickly that
1650 on a serial console, the time to write the progress updates can be the
1651 bottleneck. So mke2fs will now only update its progress indicators
1654 Resize2fs will skip initializing the inode tables if the kernel
1655 supports lazy_itable_init, which speeds up growing off-line growth of
1656 uninit_bg file systems significantly. Resize2fs will now also
1657 correctly set the itable_unused field in the block group descriptor to
1658 speed up the first e2fsck after the file system is grown.
1660 Resize2fs has been fixed so that on-line resizing of meta_bg file
1661 systems work correctly. This is needed to grow file system which are
1664 Resize2fs will now correctly handle resizing file systems to 16TB on
1665 32-bit file systems when "16TB" is specified on the command line.
1667 Fix mke2fs so that it will be careful to set the reserved blocks ratio
1668 larger than 50%; this can happen when creating small file systems and
1669 when the last block group is dropped because there are not enough
1670 blocks to support the metadata blocks in the last block group.
1672 Fixed spelling mistake in debugfs's help message.
1674 Fixed a potential seg fault in e2fsck when there is an I/O error while
1675 reading the superblock.
1677 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
1679 Updated/fixed various man pages. (Addresses Sourceforge Bug:
1685 The configure option --enable-relative-symlink was broken so that it
1686 needed to be --enable-symlink-relative-symlinks. We will support both
1687 for at least two years, but then the wrong configure option will be
1690 Fixed a regression introduced in 1.42.5 so the link order for
1691 e2fsprogs' libraries will be correct for both static and shared
1692 linking. (Addresses Sourceforge Bug: #3554345)
1694 Add support for e2fsprogs to be compiled using clang/LLVM.
1696 Fix portability problems on non-Linux systems: avoid compile failures
1697 on systems that don't have malloc.h
1699 Fix f_mmp regression test suite so that debugfs gets killed if the
1700 test is interrupted.
1704 E2fsprogs 1.42.5 (July 29, 2012)
1705 ================================
1707 Fixed a bug with mke2fs where if there is only 8 inodes per block
1708 group, the calculation of the number of uninitialized inodes in the
1709 first block group would go negative. This resulted in "mke2fs -N 256
1710 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
1711 would run out of space. (Addresses Sourceforge Bug: #3528892)
1713 Fixed a bug in how e2fsck would uniquify directory entry names.
1714 (AddressesSourceforge Bug: #3540545)
1716 Previously, e2fsck would only allow a mounted file system to be
1717 checked if it was the root file system and it was mounted read-only.
1718 Now it will allow any file system mounted read-only to be checked if
1719 the -f option is specified. This makes it easier to test how e2fsck
1720 handles checking file systems which are mounted without having to test
1721 on the root file system.
1723 Fixed a problem if e2fsck where if the root file system is mounted
1724 read-only, e2fsck would not clear an error indication in the journal
1725 superblock. Combined with a kernel bug, this would cause the e2fsck
1726 to check the file system after every single boot.
1728 The e4defrag program can now handle device symlinks, such as
1729 /dev/mapper/testvg-testlv, instead of insisting on a less
1730 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
1733 Fixed filefrag so it will not crash with a segfault on files from a
1734 virtual file system such as /proc. (e.g., "filefrag
1737 Fixed filefrag so that it correctly reports the number of extents.
1738 (Addresses Red Hat Bugzilla: #840848)
1740 Fixed a file descriptor leak in logsave which could cause it to hang.
1741 (Addresses Debian Bug: #682592)
1743 Fixed e2fsck so that the file system is marked as containing an error
1744 if the user chooses not to fix the quota usage information.
1746 Fixed tune2fs so that it correctly removes the quota feature when the
1747 last quota inode is removed.
1749 Fix tune2fs so that after removing a quota inode, the block bitmap is
1750 updated; otherwise, e2fsck would complain after running 'tune2fs -O
1753 Fix tune2fs so that when converting a file system from using legacy
1754 quota files to the new quota file system feature with hidden quota
1755 files, the accounting for these files is handled correctly so that
1756 e2fsck doesn't complain.
1758 Improved e2fsck's verbose reporting statistics, and allow the more
1759 verbose reporting to be enabled via /etc/e2fsck.conf.
1761 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
1763 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
1769 Fixed portability problems on other operating systems (e.g., Hurd and
1770 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
1772 Make sure that shared libraries link with the shared libraries built
1773 in the build tree, instead of the system provided libraries.
1774 Previously, libraries and executables were linked with the system
1775 libraries if present, and possibly using static archives instead of
1776 shared libraries. This was also problematic since if libext2fs.so is
1777 linked with a static libcom_err.a from system, the build system would
1778 attempt to link without -lpthread. (Addresses Sourceforge Bug:
1782 E2fsprogs 1.42.4 (June 12, 2012)
1783 ================================
1785 Fixed more 64-bit block number bugs (which could end up corrupting
1786 file systems!) in e2fsck, debugfs, and libext2fs.
1788 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
1789 not properly propagating the journal's s_errno field to the superblock
1790 field; it was not checking this field if the journal had already been
1791 replayed, and if the journal *was* being replayed, the "error bit"
1792 wasn't getting flushed out to disk.
1794 Fixed a false positive complaint by e2fsck if all of the extents in
1795 the last extent tree block are uninitialized and located after the end
1796 of the file as defined by i_size.
1798 The dumpe2fs will now display the journal's s_errno field if it is
1799 non-zero, and it will also display the journal's 64-bit feature flag
1802 Fix e2fsck so that it always opens the device file in exclusive mode
1803 when it might need to modify the file system, and never if the -n
1804 option is specified. (Previously, there were a few corner cases where
1805 it might get things wrong in either direction.)
1807 E2fsck now correctly truncates or deallocates extent-mapped inodes on
1808 the orphan list. The root cause was a bug in libext2fs's block
1809 iterator which could end up skipping an extent when the last block in
1810 an extent is removed, causing the current extent to be removed from
1813 E2fsck now correctly sets the global free block and inode counts when
1814 truncating or removing inodes on the orphan list in preen mode.
1815 Previously, it would leave these values would be set incorrectly,
1816 which is largely a cosmetic issue since the kernel no longer pays
1817 attention to those fields, but it can cause spurious complaints in
1818 subsequent e2fsck runs.
1820 Fix i_blocks accounting when the libext2fs library needs to add or
1821 remove an extent tree block on bigalloc file systems.
1823 The lsattr and chattr programs now support the No_COW flag for the
1826 Debugfs now interprets date strings of the form @ddd as ddd seconds
1827 after the beginning of the epoch. This is handy when setting an inode
1828 number into the d_time field when debugging orphan list handling.
1830 Fix a precedence bug with built-in quota support which might result in
1831 e2fsck paying attention to the quota inode field even if the built-in
1832 quota feature flag is not set. Fortunately, in practice that
1833 superblock field should be zero for non-built-in quota file systems,
1834 so it's unlikely this bug would have caused problems.
1836 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
1842 The regression test suite can now run the integration tests in the
1843 tests directory in parallel, via "make -jN check".
1845 Add new test, f_zero_extent_length which tests e2fsck's handling of
1846 the case where all of the extents in the last extent tree block are
1847 uninitialized extents after i_size.
1849 Add a new test, f_jnl_errno, which checks handling of an error
1850 indication set in the journal superblock.
1852 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
1853 of a 64-bit journal.
1855 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
1856 tests e2fsck's handling of orphan inodes in preen mode, and truncation
1857 of extent inodes on the orphan list.
1859 Fixed more OS X portability issues.
1862 E2fsprogs 1.42.3 (May 14, 2012)
1863 ===============================
1865 Fix a bug in the Unix I/O manager which could cause corruption of file
1866 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
1867 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
1868 dumpe2fs to incorrectly display block numbers > 32-bits.
1870 Improve the support for integrated quota files (where quota is a first
1871 class supported feature using hidden files in the ext4 file system).
1872 Previously the quota file was getting rewritten even when it was not
1873 necessary, and e2fsck would erroneously try to hide quota files which
1874 were already hidden.
1876 Quiet complaints in e2fsck when the total free blocks or inodes are
1877 incorrect in the superblock after an system crash, since we don't
1878 update nor depend on the superblock summaries at each commit boundary.
1880 Fixed a regression introduced in 1.42.2 which would cause applications
1881 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
1882 would were still using the legacy 32-bit bitmaps) to crash. This was
1883 due to missing 32-bit compat code in side the function
1884 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
1887 Fix a bug which would cause mke2fs to fail creating the journal if
1888 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
1891 Updated/fixed various man pages.
1893 Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
1896 Fixed various Debian Packaging issues.
1902 Change the nonsensically wrong types in the function signature of the
1903 inline function ext2fs_find_first_zero_block_bitmap2(). This was
1904 caused by a cut and paste error; fortunately no code in e2fsprogs used
1905 this inline function, and there are any users of this functions
1906 outside of e2fsprogs.
1908 Add support for systems which have valloc(), but which do have
1909 posix_memalign() nor memalign() (such as MacOS 10.5).
1911 Refactor and clean up the allocation of aligned buffers for Direct I/O
1912 support. Previously some allocations were requesting a greater
1913 alignment factor that what was strictly necessary. Also optimize
1914 reading and writing bitmaps using Direct I/O when the size of the
1915 bitmap did not fully cover the file system blocksize.
1917 Reserve the codepoints for the INCOMPAT features LARGEDATA and
1920 Improved the regression test suite by adding some new integration
1921 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
1922 jbd2 format, as well as f_eofblocks which tests the new handling of
1923 uninitialized and initialized blocks beyond i_size. Also add a new
1924 unit test which verifies 32-bit bitmaps support and the new
1925 find_first_zero primitives.
1927 Add a few dependencies to fix parallel (make -j) builds.
1929 Removed bash'isms which were breaking the regression test suite on
1930 systems where /bin/sh is not bash.
1932 The config.guess and config.sub have been updated to the 2012-02-10
1935 Fix a portability problem caused by assuming the present of mntent.h
1936 means that setmntent() exists. Instead, explicitly test for this in
1937 the configure script.
1939 If the sys/signal.h header file does not exist, don't try to include
1940 it, since it's not available on all systems.
1942 Add support for systems that do not support getpwuid_r()
1944 The configure script now supports a new option,
1945 --enable-relative-symlinks, which will install relative symlinks for
1946 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
1948 When building BSD shared libraries make sure the LDFLAGS variable is
1949 passed to the linker. Fixing this allows, for example, e2fsprogs to
1950 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
1953 Fix gcc -Wall nitpicks
1956 E2fsprogs 1.42.2 (March 27, 2012)
1957 =================================
1959 The resize2fs program uses much less CPU and is much faster for very
1960 large file systems. (Addresses Debian Bug: #663237)
1962 The seti and freei commands in debugfs can now take an optional length
1963 argument to set and clear a contiguous range of inodes.
1965 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
1966 plan to remove support for it from the kernel file system driver. It
1967 really wasn't very useful and was causing more problems than it
1968 solves. Since e2fsck will complain if inodes that should have
1969 EOFBLOCKS_FL do not have the flag set, we are going to remove this
1970 check from e2fsprogs first, and then only remove the flag from the
1973 The mke2fs program can now use direct I/O via "mke2fs -D". This will
1974 slow down the mke2fs, but it makes it more polite on a loaded server
1975 by limiting the amount of memory that gets dirtied by mke2fs when it
1976 is using buffered I/O.
1978 E2fsck was needlessly closing and re-opening the file system as a side
1979 effect of adding Multiple Mount Protection (MMP). This isn't
1980 necessary for non-MMP file systems, so drop it.
1982 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
1983 can more easily diagnose memory allocation failures caused by
1984 insufficient memory. E2fsck will now abort if there are memory
1985 allocation failures when the file system is initially opened and
1986 during the block group descriptor checks. (Addresses Google Bug:
1989 If there are incorrect block group checks, e2fsck will now report the
1990 incorrect and corrected checksum values.
1992 The e2fsck program can now write log files containing the details of
1993 the problems that were found and fixed directly, via configuration
1994 parameters in /etc/e2fsck.conf.
1996 Added the ability to limit the number of messages reported by e2fsck
1997 for a given problem type. This avoids a potential bottleneck if there
1998 is a serial console which can cause a boot sequence to take a long
1999 time if e2fsck needs to report many, many file system errors.
2001 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
2002 them to use much less memory for large file systems.
2004 The dumpe2fs program will now print the expected block group checksum
2005 if it is incorrect. This helps to diagnose problems caused by
2006 incorrect block group checksums.
2008 E2fsck now checks for extents with a zero length, since the kernel
2009 will oops if it comes across such a corrupted data structure. (See
2010 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
2012 E2fsck has a number of bugs relating to discard that have been fixed.
2013 (1) Fixed a bug which could cause e2fsck to discard portions of the
2014 inode table which were actually in use. (2) E2fsck will now avoid
2015 using discard if the block device doesn't zero data on discard, since
2016 otherwise this could cause problems if the file system gets corrupted
2017 in the future. (3) E2fsck will now avoid using discard when it is run
2018 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
2019 discards in the last block group.
2021 E2fsck's CPU utilization in pass 5 has been optimized, which will
2022 speed up e2fsck slightly.
2024 E2image will now skip copying uninitialized bitmap and inode table
2027 Fixed mke2fs -S so it does not corrupt the first block group's
2030 E2fsck will now check the new sysfs interface to determine if we are
2031 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
2033 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
2035 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
2040 Fixed various portability issues for non-Linux systems, particularly
2041 MacOS X, as well as Linux systems running with the just-released glibc
2044 Fix file descriptor leak in ext2fs_close() if the file system with
2045 uninit_bg is opened read/only with a backup superblock. (Addresses
2046 SourceForge Bug: #3444351)
2048 Fixed an invalid return in a non-void function in the quota code.
2049 (Addresses SourceForge Bug: #3468423)
2051 Fixed the debian rules file so that the calls to dpkg-buildflags works
2052 when the shell is dash.
2054 The debian package build now uses V=1 so that there is more
2055 information about potential build failures in debian build logs.
2057 If the uninit flags get cleared by functions such as
2058 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
2059 superblock is marked dirty and the block group descriptor checksum is
2060 updated if necessary.
2062 The debian rules file will now try to load debian/rules.custom of it
2063 exists. This file can skip various builds for speed reasons if there
2064 is no need for the e2fsck-static or udeb packages. Available
2065 customizations in the rules file includes SKIP_STATIC=yes,
2066 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
2068 In addition, if the file misc/mke2fs.conf.custom.in exists in the
2069 source tree, it will be used instead of the standard misc.conf file in
2070 the upstream sources. This makes it easier for Debian-derived systems
2071 to distribute a custom mke2fs.conf file without having to worry about
2072 merge issues if future versions of e2fsprogs makes changes in the
2073 upstream default version of mke2fs.conf.
2076 E2fsprogs 1.42.1 (February 17, 2012)
2077 ===================================
2079 The mke2fs and e2fsck now use significantly less memory when creating
2080 or checking very large file systems. This was enabled by adding
2081 extent-based bitmaps which are stored using a red-block tree, since
2082 block and inode allocations tend to be contiguous.
2084 The command mke2fs -S is used as a last ditch recovery command to
2085 write new superblock and block group descriptors, but _not_ to destroy
2086 the inode table in hopes of recovering from a badly corrupted file
2087 system. So if the uninit_bg feature is enabled, mke2fs -S will now
2088 set the unused inodes count field to zero. Otherwise, e2fsck -fy
2089 after using mke2fs -S would leave the file system completely empty.
2091 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
2092 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
2093 installed an mke2fs binary using that name.
2095 The usage and help messages for the -G, -t and -T options in mke2fs
2098 If e2fsck needs to use the backup group descriptors, the
2099 ext2fs_open2() function clears the UNINIT bits to ensure all of the
2100 inodes in the file systems get scanned. However, the code which reset
2101 the UNINIT flags did not also recalculate the checksum, which produced
2102 many spurious (and scary) e2fsck messages. This has been fixed by
2103 resetting checksums when the UNINIT bits are cleared.
2105 Relax a check in e2fsck which required that the block bitmap to be
2106 initialized when the inode bitmap is in use. This will allow us to
2107 eventually eliminate code from the kernel which forcibly initialized
2108 the block bitmap when the inode bitmap is first used, requiring an
2109 extra journal credit and disk write. (Addresses Google Bug: #5944440)
2111 Make sure rdebugfs (which may be installed setuid or setgid disk) does
2112 not honor environment variables if euid != uid or egid != gid.
2114 Debugfs's ncheck command has been optimized and now is much more
2115 robust with faced with corrupted file systems. The ncheck command
2116 also now has a -c option which will verify the file type information
2117 in the directory entry to see if matches the inode's mode bits. This
2118 is extremely useful when trying to use debugsfs to determine which
2119 parts of the file system metadata can be trusted.
2121 E2image will try to use ftruncate64() to set the i_size for raw
2122 images, instead of writing a single null byte. This avoid allocating
2123 an extra block to the raw image, for those file systems and/or
2124 operating systems that support this. (Linux does.) In addition, fix
2125 a logic bug that caused the file to not be properly extended if the
2126 size of the last hole was exactly an multiple of a megabyte.
2128 Fixed a bug in resize2fs where for 1k and 2k file systems, where
2129 s_first_data_block is non-zero, this wasn't taken into account when
2130 calculate the minimum file system size for use with the -M option.
2132 Fixed the badblocks program to honor the -s flag when in read-only -t
2133 mode. (Addresses Debian Bug #646629)
2135 Update Czech, Dutch, French, Polish, and Swedish translations from the
2136 Translation Project.
2138 Fixed various Debian Packaging issues so that dpkg-buildflags is used
2139 if present, which allows e2fsprogs to be built with security hardening
2140 flags. (Addresses Debian Bugs: #654457)
2145 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
2146 This was only an issue for programs compiled against e2fsprogs 1.41
2147 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
2150 The libext2fs library now uses sysconf() to fetch the page size, instead
2151 of the deprecated getpagesize().
2153 The ext2fs_get_pathname() function will return a partial path if an a
2154 directory in the path is not a directory, displaying it as an inode
2155 number in angle brackets instead of giving up and displaying an error.
2156 This is much more helpful when a user is trying to debug a corrupted
2159 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
2161 Added a new library function, ext2fs_file_get_inode_num(), for use by
2164 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
2165 file, it actually works.
2167 The block iterator now properly honors the BLOCK_ABORT flag for
2168 extent-based flags. Previously, it didn't, which generally made code
2169 be less efficient, but it could cause bugs in ext2fs_link(), for
2170 example, by causing it to insert multiple directory entries.
2172 Fixed an (harmless other than causing a compiler warning) use of an
2173 uninitialized variable in e2fsck's MMP code.
2176 E2fsprogs 1.42 (November 29, 2011)
2177 ==================================
2179 This release of e2fsprogs has support for file systems > 16TB. Online
2180 resize requires kernel support which will hopefully be in Linux
2181 version 3.2. Offline support is not yet available for > 16TB file
2182 systems, but will be coming.
2184 This release of e2fsprogs has support for clustered allocation. This
2185 reduces the number of block (now cluster) bitmaps by allocating and
2186 deallocating space in contiguous power-of-2 collections of blocks,
2187 which are called clustered. This is a file system level feature,
2188 called 'bigalloc', which must be enabled when the file system is
2189 initially formatted. It is not backwards compatible with older
2192 Added support for the Multi-Mount Protection (MMP) feature.
2194 E2fsck more efficiently uses scratch files for really big file
2195 systems. (This is a feature that has to be turned on explicitly; see
2196 [scratch_files] in the e2fsck.conf man page.)
2198 Fix a bug in e2fsck where if the free blocks and inodes counts are
2199 incorrect, e2fsck would fix them without printing an error message.
2200 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
2201 any explanation of what was fixed.
2203 E2fsck will no longer attempt to clone an extended attribute block in
2204 pass1b handling if the file system does not support extended
2207 E2fsck will be more careful accidentally asking the user to continue
2208 if the file system is mounted, so that an escape sequence won't cause
2209 a false positive. (Addresses Debian Bug: #619859)
2211 E2fsck now uses less cpu time in pass 5 when large portions of the
2212 bitmaps are uninitialized.
2214 E2fsck will no longer segfault when a corrupted file system has a bad
2215 extent, and removing it leads to a block needing to be deallocated.
2216 (Addresses SourceForge Bug: #2971800)
2218 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
2219 and print debugging information to make it easier to find potential
2222 E2fsck will check to see if the bad block inode looks insane, and will
2223 skip trying to use if it certain fields which should be zero look
2224 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
2225 to get confused and do more harm than good.
2227 If e2fsck modifies certain superblock fields which the kernel doesn't
2228 look at, it will now mark the superblock as dirty without marking the
2229 file system as changed. This avoids signaling the init scripts that
2230 a reboot is necessary, since the kernel isn't going to look at those
2231 fields, so it won't care if they have been changed.
2233 Fixed a bug in the libext2fs library (in the binary search routine of
2234 the icount abstraction) that could (very, very rarely) cause e2fsck to
2235 die in the middle of pass 1 or pass 2 processing.
2237 E2fsck will not try to do a discard operation if the -n option was
2238 specified on the command line.
2240 E2fsck now supports an extended "discard" option which will cause
2241 e2fsck to attempt discard all unused blocks after a full, successful
2244 E2fsck will check for the bad block inode to make sure it looks sane
2245 before trusting it, to avoid causing more harm than good to the file
2248 E2fsck now returns additional status bits in its exit code if it
2249 aborts early in the e2fsck run.
2251 E2fsck now correctly calculates the maximum file size in the case of
2252 the huge_file file system feature enabled without extents.
2254 The mke2fs and e2fsck programs now tries to use the punch hole command
2255 as a "discard" when operating on normal files.
2257 The e2image program now supports the qcow2 format, which is a more
2258 efficient way of capturing file system dumps.
2260 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
2261 per-device defaults to be specified in the configuration file.
2263 Mke2fs now supports the reserved_ratio relation in the [defaults] and
2264 [fs_types] section in mke2fs.conf.
2266 Mke2fs now creates extent-mapped directories for the root and
2267 lost+found directories.
2269 Mke2fs will skip zero'ing the journal if the extended option
2270 "lazy_journal_init" is specified. This can save a lot of time, but it
2271 does add a small amount of risk if the system crashes before the
2272 journal is overwritten entirely once. It is especially useful for
2275 Mke2fs will now create file systems that enable user namespace
2276 extended attributes and with time- and mount count-based file
2277 system checks disabled.
2279 Mke2fs will not set a stride or strip size of one block based on block
2280 device attributes obtained from sysfs.
2282 Mke2fs now displays a progress report during the discard process.
2284 Mke2fs now handles extreme file system parameters correctly which
2285 previously caused the inodes per group to drop below 8, leading to a
2286 segfault. (The inodes per group must be a multiple of 8, but the code
2287 didn't correctly deal with an inodes per group count less than 8.)
2289 Mke2fs and tune2fs previously would give an error if the user tried
2290 setting the stride and stripe-width parameters to zero; but this is
2291 necessary to disable the stride and stripe-width settings. So allow
2292 setting these superblock fields to zero. (Addresses Google Bug:
2295 Mke2fs now gives a warning if the auto-detected block size exceeds the
2298 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
2299 is the default), mke2fs will now set the s_max_mnt_count superblock
2300 field to -1, instead of 0. Kernels older then 3.0 will print a
2301 spurious message on each mount then they see a s_max_mnt_count set to
2302 0, which will annoy users. (Addresses Debian Bug: #632637)
2304 The default mke2fs.conf now has entries for "big" and "huge", which
2305 are needed for very big file systems.
2307 The resize2fs program now has support for a new online resize ioctl
2308 that can support file systems > 16TB, once it arrives in v3.x kernels.
2310 Fixed bug which caused resize2fs to fail when shrinking an empty file
2311 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
2313 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
2315 Allow tune2fs to remove external journals if the device can not be
2318 Debugfs's icheck will now correctly find inodes which use the
2319 searched-for block as an extended attribute block.
2321 Debugfs now has a new "punch" command which remove blocks from the
2324 Debugfs now has a new "e2freefrag" command which analyzes the free
2325 space fragmentation of the file system, using the same code as the
2328 Debugfs now has a "filefrag" command which displays information about
2329 a file's fragmentation.
2331 Add support to build a metadata-only, read-only, stripped-down version
2332 of debugfs called rdebugfs.
2334 Fixed a potential stack overrun bug in debugfs.
2336 The badblocks program now correctly recovers from I/O errors when
2337 direct I/O is being used. The badblocks command now also supports a
2338 -B option which forces the use of buffered I/O, and the -v option will
2339 provide a more detailed breakdown of read, write, and failed
2342 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
2344 Added support for journals larger than 2GB.
2346 Support using both hard links and symlinks when installing e2fsprogs.
2348 Add overflow checking to tune2fs -i's fsck interval, which must fit in
2351 The debugfs command now has a new 'blocks' command which prints out
2352 data blocks of a particular inode in a format which is useful for
2355 Filefrag will report 0 extents correctly in verbose mode. (Addresses
2356 RedHat Bugzilla: #653234)
2358 Filefrag has been fixed so its -v report prints the correct expected
2359 block number (previously there had been an off-by-one error). In
2360 addition, it will now display the number of contiguous extents when -v
2361 is not specified. This makes it consistent with the number of extents
2362 printed when the -v option was specified. In addition, the number of
2363 contiguous extents is far more interesting/useful than the number of
2364 physical extents for very large files. (Addresses Debian Bug:
2367 Logsave's usage message has been fixed. (Addresses Debian Bug:
2370 Avoid an infinite loop in ext2fs_find_block_device() if there are
2371 symlink loops in /dev caused by a buggy udev.
2373 Added a useful "fallocate" program to the contrib directory.
2375 Fixed an ABI compatibility problem in libext2fs which broke the dump
2376 program. Also added back some macros which dump needed so it could
2377 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
2380 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses

2383 Added internationalization support for libcom_err error table strings.
2385 Fixed various spelling mistakes found in various output strings found
2386 by I18N translators.
2388 Update translations: French, Chinese, Germany, Indonesian, Swedish,
2389 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
2392 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
2393 #614662, #632169, #641838, #627535, #629355)
2395 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
2401 Initial support for quota as an integrated feature, where the quota
2402 files are hidden system files that are automatically maintained by
2403 e2fsck is present, although disabled by default. It must be enabled
2404 by using the configure option --enable-quota.
2406 Reserved the on-disk fields for the metadata checksum and snapshot
2407 features, which are currently in development.
2409 The ext2fs library now has the new functions ext2fs_punch(),
2410 ext2fs_get_memzero() and ext2fs_file_get_inode().
2412 The ext2fs library now has support for calculating the crc32c checksum
2413 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
2415 The I/O manager now supports the discard operation.
2417 Reserved file system code points for new 1st class quota feature.
2419 Shortened the compilation lines by moving the autoconf defines to
2420 a config.h header file.
2422 Fixed a potential free of an uninitialized pointer in
2423 ext2fs_update_bb_inode().
2425 Fixed miscellaneous gcc -Wall and coverity warnings.
2427 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
2429 Fixed a build failure when OMIT_COM_ERR is defined.
2431 Improved error checking and fixed memory leaks caused by error return
2434 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
2435 the fsync() to be skipped.
2437 Added a test for extent-mapped journals by mke2fs and tune2fs.
2439 Added a test for creating a large (over 4GB) journal using mke2fs.
2441 Added a test to make sure the inode size remains constant.
2443 The regression test script now prints the list of which tests failed.
2445 The regression test system now uses /tmp for its scratch files, which
2446 is often a tmpfs mounted file system and hence much faster.
2448 The i_e2image test was fixed so it works with valgrind.
2450 Tests that rely on debugfs are now skipped if debugfs wasn't built.
2452 Fixed the dependencies for "make check" so all required dependencies
2453 are built before running the regression tests.
2455 A link to com_err.h is installed in $(includedir) during a "make install".
2457 The po/*.gmo files are automatically rebuilt if they are missing or
2458 out of date. This helps out Debian packaging.
2460 Allow ext2fs_get_memalign() to compile on systems that don't have
2463 Fixed a namespace leak in libext2fs (tdb_null).
2466 E2fsprogs 1.41.14 (December 22, 2010)
2467 =====================================
2469 Fix spurious complaint in mke2fs where it would complain if the file
2470 system type "default" is not defined in mke2fs.conf.
2472 The resize2fs program will no longer clear the resize_inode feature
2473 when the number reserved group descriptor blocks reaches zero. This
2474 allows for subsequent shrinks of the file system to work cleanly for
2475 flex_bg file systems.
2477 The resize2fs program now handles devices which are exactly 16T;
2478 previously it would give an error saying that the file system was too
2481 E2fsck (and the libext2fs library) will not use the extended rec_len
2482 encoding for file systems whose block size is less than 64k, for
2483 consistency with the kernel.
2488 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
2489 been fixed. (Addresses Sourceforge Bug: #3138115)
2491 The ext2fs_block_iterator2() function passed an incorrect ref_offset
2492 to its callback function in the case of sparse files. (Addresses
2493 Sourceforge Bug: #3081087)
2495 Fix some type-punning warnings generated by newer versions of gcc.
2498 E2fsprogs 1.41.13 (December 13, 2010)
2499 =====================================
2501 E2fsck now supports the extended option "-E journal_only", which
2502 causes it to only do a journal replay. This is useful for scripts
2503 that want to first replay the journal and then check to see if it
2506 E2fsck will now support UUID= and LABEL= specifiers for the -j option
2507 (which specifies where to find the external journal). (Addresses
2510 E2fsck now has support for the problems/<problem code>/force_no
2511 configuration option in e2fsck.conf, which forces a problem to not be
2514 Dumpe2fs will now avoid printing large negative offsets for the bitmap
2515 blocks and instead print a message which is a bit more helpful for
2516 flex_bg file systems.
2518 Mke2fs will now check the file system type (specified with the -t
2519 option) to make sure it is defined in the mke2fs.conf file; if it is
2520 not, it will print an error and abort. If the usage type (specified
2521 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
2522 warning but will continue. (Addresses Debian Bug #594609)
2524 Clarified error message from resize2fs clarifying that on-line
2525 shrinking is not supported at all. (Addresses Debian Bug #599786)
2527 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
2528 displayed. (Addresses Debian Bug #555456)
2530 E2fsck will open the external journal in exclusive mode, to prevent
2531 the journal from getting truncated while it is in use due to a user
2532 accidentally trying to run e2fsck on a snapshotted file system volume.
2533 (Addresses Debian Bug #587531)
2535 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
2538 The tune2fs program can now set the uninit_bg feature without
2541 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
2542 default mount options settings which were added in 2.6.35.
2544 The e2fsck and dumpe2fs programs now support the new ext4 superblock
2545 fields which track where and when the first and most recent file
2546 system errors occurred. These fields are displayed by dumpe2fs and
2547 cleared by e2fsck. These new superblock fields were added in 2.6.36.
2549 Debugfs now uses a more concise format for listing extents in its
2550 stat command. This format also includes the interior extent tree
2551 blocks, which previously was missing from stat's output for
2554 Debugfs has a new option, -D, which will request Direct I/O access of
2557 Mke2fs will skip initializing the inode table if a device supports
2558 discard and the discard operation will result in zero'ed blocks.
2560 Badblocks will now correctly backspace over UTF-8 characters when
2561 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
2562 Debian Bugs #583782 and #587834)
2564 E2freefrag will now display the total number of free extents.
2566 Resize2fs -P no longer requires a freshly checked filesystem before
2567 printing the minimum resize size.
2569 Fixed a floating point precision error in a binary tree search routine
2570 that can lead to seg fault in e2fsck and resize2fs.
2572 Fixed a bug in e2fsck where if both the original and backup superblock
2573 are invalid in some way, e2fsck will fail going back to the original
2574 superblock because it didn't close the backup superblock first, and
2575 the exclusive open prevented the file system from being reopened.
2577 Fixed a big in e2freefrag which caused getopt parsing to fail on
2578 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
2580 Clarified an mke2fs error message so a missed common in an -E option
2581 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
2582 results in a more understandable explanation to the user.
2584 Mke2fs now displays the correct valid inode ratio range when
2585 complaining about an invalid inode ratio specified by the user.
2587 Mke2fs now understands the extended option "discard" and "nodiscard",
2588 and the older option -K is deprecated. The default of whether
2589 discards are enabled by default can be controlled by the mke2fs.conf
2592 Mke2fs's handling of logical and physical sector sizes has been
2593 improved to reflect the fact that there will be some SSD's with 8k and
2594 16k physical sectors arriving soon. Mke2fs will no longer force block
2595 size to be the physical sector size, since there will be devices where
2596 the physical sector size is larger than the system's page size, and
2597 hence larger than the maximal supported block size. In addition, if
2598 the minimal and optimal io size are not exported by the device, and
2599 the physical sector size is larger than the block size, the physical
2600 sector size will be used to set the Raid I/O optimization hints in the
2603 E2fsck will now display a better, more specific error message when the
2604 user enters a typo'ed device name, instead of blathering on about
2605 alternate superblocks.
2607 Fixed various Debian Packaging Issues
2609 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
2610 #589345, #591083; Addresses Launchpad Bug: #505719)
2612 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
2613 Polish, Swedish, and Vietnamese translations.
2619 Fix a dependency definition for the static and profiled blkid
2620 libraries which could cause compile failures in some configurations.
2621 (Addresses Debian Bug: #604629)
2623 Add support for Direct I/O in the Unix I/O access layer.
2625 Fixed a memory leak in the Unix I/O layer when changing block sizes.
2627 Fixed minor memory leaks in mke2fs.
2629 Added a new function to the ext2fs library, ext2fs_get_memalign().
2631 The tst_super_size test program will check to make sure the superblock
2632 fields are correctly aligned and will print them out so they can be
2633 manually checked for correctness.
2635 Fixed some makefile dependencies for test programs in lib/ext2fs.
2637 Reserved the feature flags and superblock fields needed for the Next3
2640 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
2641 EXT4_INCOMPAT_EA_INODE.
2644 E2fsprogs 1.41.12 (May 17, 2010)
2645 ================================
2647 Mke2fs now gives a correct error message if the external journal
2648 device is not found. (Addresses Red Hat Bug #572935)
2650 Resize2fs -P will now refuse to print a minimum size if the file
2651 system is not clean. Previously it would go ahead and print a minimum
2652 size anyway, which might not be correct, leading to user confusion.
2654 E2fsck now tests for extents that begin at physical block 0 and
2655 rejects them as invalid. (Addresses Google Bug: #2573806)
2657 Fixed a bug in e2fsck which could cause it to crash when trying to
2658 remove an invalid extent and the block bitmaps hadn't yet been loaded.
2659 (Addresses SourceForge Bug: #2971800)
2661 E2fsck now will completely skip time-based checks if the system clock
2662 looks insane or the option broken_system_clock is set in
2665 E2fsck would previously report an i_blocks corruption for a 4T file
2666 created using posix_fallocate; this bug has been fixed.
2668 E2fsck will now correctly mark a sparse journal as invalid and will
2669 delete and recreate the journal to address the problem.
2671 E2fsck would previously incorrectly ask the user whether she would
2672 like to abort the file system check after finding a problem --- and
2673 then abort regardless of the user's answer. This is annoying, and
2676 E2fsck can now continue even if it fails to recreate the resize
2677 inode; previously it would just abort the file system check
2680 E2fsck could potentially remove directory entries for inodes found in
2681 the unused region of the inode table; this would generally happen on
2682 ext4 file systems that do not use journalling. This bug has been fixed
2683 by not clearing these directory entries once it has been established
2684 that bg_unused_inodes may not be trustworthy; once pass #2 has been
2685 completed, e2fsck will restart the file system check from the
2686 beginning, and then it will be safe to delete any directory entries
2687 pointing to inodes that appear to be deleted. (Addresses Google Bug:
2690 E2fsck will not try to set the block group checksums if the user
2691 cancels the fsck with a control-C. It's a bad idea to set the
2692 checksums if e2fsck hasn't been completed, and it often results an the
2693 error message, "Inode bitmap not loaded while setting block group
2694 checksum info". (Addresses Launchpad Bug: #582035)
2696 The mke2fs program now queries the kernel for the physical as well as
2697 the logical sector size, and will not allow a blocksize below the
2698 logical, and will strongly encourage a blocksize at least as big as
2699 the physical blocksize. This is needed for 4k sector drives that
2700 emulate 512 byte sector sizes.
2702 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
2703 rarely needed, but it is a legal value.
2705 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
2706 not needed, and offer to clear it; this is a sign of a kernel bug, but
2707 more importantly, some released kernels may crash when this situation
2708 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
2710 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
2711 i_size is correct. (Kernels starting with 2.6.34 will set
2714 The com_err library will now only output ^M (a CR character) when the
2717 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
2718 and Vietnamese translations.
2720 Fixed various Debian packaging issues --- see debian/changelog for
2721 details. (Addresses Debian Bugs: #571247, #563487)
2727 The regression test suite now uses its own mke2fs.conf file, so that
2728 downstream distributions want change the mke2fs.conf file which is
2729 distributed in the RPM or dpkg file, without worrying about screwing
2730 up the regression test results.
2732 Always build namei.o so that building with configure --disable-debugfs
2733 works correctly. Long-term, if we care about reduced e2fsprogs
2734 builds, we need a more general solution for deciding what .o files are
2735 needed for a particular build. Given that install floppies are going
2736 (gone?) the way the dodo bird, we probably don't care, though.
2737 (Addresses Sourceforge Bug: #2911433)
2739 Add configure options --enable-symlink-build and
2740 --enable-symlink-install, which allow e2fsprogs be built using
2741 symlinks instead of hard links, and to be installed using symlinks
2742 instead of hard links, respectively. It is useful when the file
2743 system where the build is taking place, or the file system where
2744 e2fsprogs is installed, can't handle hard links for some reason.
2745 (Addresses Sourceforge Bug: #1436294)
2747 Fixed compile warning in mke2fs.c.
2750 E2fsprogs 1.41.11 (March 14, 2010)
2751 ==================================
2753 E2fsck will no longer give a fatal error and abort if the physical
2754 device has been resized beyond 2**32 blocks. (Addresses Launchpad
2757 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
2758 the allocation status of the block <blk>. (Addresses Debian Bug:
2761 E2fsck now prints a much more emphatic and hopefully scary message
2762 when a file system is detected as mounted while doing a read/write
2763 check of the filesystem. Hopefully this will dissuade users from
2764 thinking, "surely that message doesn't apply to *me*" :-(
2766 E2fsck -n will now always open the file system read-only. We now
2767 disallow certain combination of options which previously were manual
2768 exceptions; this is bad because it causes users to think they are
2769 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
2770 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
2772 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
2773 it detected a badly aligned partition. Unfortunately, this broke some
2774 distribution installation scripts, so it now just prints the warning
2775 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
2776 Launchpad Bug: #530071)
2778 Mke2fs would take a long time to create very large journal files for
2779 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
2782 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
2783 2.6.34 kernels to make e2fsck not complain about blocks deliberately
2784 fallocated() beyond an inode's i_size.
2786 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
2787 e2fsck -fD can corrupt non-indexed directories when are exists one or
2788 more file names which alphabetically sort before ".". This can happen
2789 with ext2 filesystems or for small directories (take less than a lock)
2790 which contain filenames that begin with a space or some other
2791 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
2798 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

2811 Add libss support for libreadline.so.6.
2813 Fix e2fsck's check for extent-mapped directory with an incorrect file
2816 Add new e2fsck.conf configuration option, default/broken_system_clock
2817 to support systems with broken CMOS hardware clocks. Also, since too
2818 many distributions seem to have broken virtualization scripts now,
2819 e2fsck will by default accept dates which are off by up to 24 hours by
2820 default. (Addresses Debian Bugs: #559776, #557636)

2823 table when there is only room for a single block group in the last
2826 E2fsck is now smarter when it needs to allocate blocks in the course
2827 of fixing file system problems. This reduces the number of spurious
2828 differences found in pass #5.
2830 E2fsck will no longer rehash directories which fit in a single
2833 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
2834 sparse directories which use extents).
2836 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
2838 Fix a bug in filefrag where on platforms which can allow file systems
2839 with 8k blocks, that it doesn't core dump when it sees a file system
2840 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
2843 E2fsck will correctly fix directories that are have an inaccurate
2844 i_size as well as other problems in a single pass, instead of
2845 requiring two e2fsck runs before the file system is fully fixed.
2847 Fix e2fsck so it will correctly find and detect duplicate directory
2848 entries for non-indexed directories. ( Addresses Sourceforge Bug:

2865 journals instead of failing early with the error "Illegal inode
2868 Fix libss so that it does not seg fault when using a readline library
2869 which does not supply a readline_shutdown() function.

2875 Teach libext2fs to ignore the high 32 bits of the i_blocks field
2876 when huge_file file system feature is set, but the inode does not
2877 have the HUGE_FILE_FL flag set.
2879 Fix e2fsck's handling of 64-bit i_blocks fields.
2881 E2fsck will now print "Illegal indirect block", "Illegal
2882 double-indirect block", etc., instead of "Illegal block #-1" or
2883 "Illegal block #-2", etc. This makes it easier for users to
2884 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
2886 Mke2fs now will obtain get device topology information from blkid and
2887 use it to populate the superblock stride and stripe sizes. It will

2941 E2fsprogs 1.41.9 (August 22, 2009)
2942 ==================================
2944 Fix a bug in e2fsck routines for reallocating an inode table which
2945 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
2946 filesystem feature with a relatively rare (and specific) filesystem
2947 corruption. This fix causes e2fsck to try to find space for a new
2948 portion of the inode table in the containing flex_bg, and if that
2949 fails, the new portion of the inode table will be allocated in any
2950 free space available in the filesystem.
2952 Make e2fsck less annoying by only asking for permission to relocate a
2953 block group's inode table once, instead of for every overlapping
2954 block. Similarly, only ask once to recompute the block group
2955 checksums, instead of once for each corrupted block group's checksum.
2957 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
2958 not present, and it needs to fall back to using the FIBMAP ioctl.
2960 Fix filefrag to correctly print the number of extents for zero-length
2961 files. (Addresses Debian Bug: #540376)
2963 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
2964 to more easily debug the FIBMAP code.
2966 Fixed filefrag for non-extent based files.
2968 Add a new program, e2freefrag, which displays information about the
2969 free space fragmentation in an ext2/3/4 filesystem.
2971 Fix inode resizing via tune2fs -I so that it works correctly in the
2972 face of non-empty bad blocks inodes, and if the filesystem was
2973 formatted using the "mke2fs -E stride=N" option for RAID arrays.
2975 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
2976 and corrupt large directories if the directory needs to shrink by more
2977 than one block. (Addresses Debian Bug: #537510)
2979 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
2980 last mount times are in the future, they are corrected even if
2981 buggy_init_scripts is set. This is needed because otherwise resize2fs
2982 will refuse to resize the filesystem, even after running "e2fsck -f".
2983 (Addresses Launchpad bug: #373409)
2985 E2fsck will now print much fuller information when the last mount time
2986 or last written time is in the future, since most people can't seem to
2987 believe their distribution has buggy init scripts, or they have a
2988 failed CMOS/RTS clock battery.

3013 there aren't any free blocks or inodes in the already-used block

3083 bytes when operating on inodes mapped via extents; potentially
3084 corrupting filesystems.
3086 Fix memory leaks in e2fsprogs, including a very large memory leak
3087 which can cause e2fsck to run out of memory when checking very large
3088 filesystems using extents.
3090 The logsave program will now filter out the ^A and ^B characters when
3091 writing to the console.
3093 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
3094 end of the block even if the directory block is corrupted.
3096 Fix debugfs from core dumping if the logdump command fails to open the
3099 Enhance badblocks to print the currently tested block number when
3100 interrupted with ^C.
3102 Fix lsattr to exit with a non-zero status when it encounters errors.
3103 (Addresses RedHat Bugzilla #489841)
3105 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
3106 filesystems as the kernel when encoding rec_len >= 64k. For 64k
3107 filesystems (currently all that is supported by e2fsprogs, this is
3108 only a minor corner case).
3110 Resize2fs will now update the journal backup fields in the superblock
3111 if the journal is moved; this avoids an unnecessary full fsck after
3112 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
3114 Fix libext2fs to properly initialize i_extra_size when creating the
3115 journal and resize inodes.

3135 valgrind with the appropriate options to find memory leaks.
3138 E2fsprogs 1.41.6 (May 30, 2009)
3139 ===============================
3141 Fix a critical regression in e2fsck introduced version 1.41.5 which
3142 can undo updates to the block group descriptors after a journal replay.
3144 If e2fsck receives an I/O error while replaying the journal, prompt
3145 the user whether they want to ignore the error or not; if e2fsck is
3146 run in preen mode, force fsck to abort the preen pass.
3148 Fix a bug which would cause e2fsck to core dump if the filesystem
3149 contains a corrupt extent header, and the user declines to clear the
3150 inode. (Addresses Sourceforge Bug: #2791794)
3152 Fix e2fsck to restart only once in the case of multiple block groups
3153 which inodes in use that are in the uninitialized part of the block
3154 group's inode table.
3156 To reduce user confusion, if the /etc/mtab file is missing
3157 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
3158 new, explicit error code to indicate this case. This will cause
3159 e2fsck to give a clearer error message when the user is using buggy
3160 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
3163 Fix e2fsck so that if the primary group descriptors are corrupted, but
3164 the backup superblock is entirely invalid, to go back to using (and
3165 fixing) the primary group descriptors instead of completely giving up
3166 on the filesystem. (Addresses Debian Bug: #516820)
3168 Change e2fsck to not abort a preen pass if an inode is found to have
3169 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
3170 kernels (post 2.6.29) will ignore this field. So let's fix it
3171 automatically during the preen pass instead of forcing the user to fix
3172 this up manually. (Addresses Debian Bug: #526524)
3174 Add resource tracking for e2fsck passes 1b through 1d.
3176 Speed up e2fsck by eliminating unnecessary journal checks if the
3177 filesystem is already mounted and doesn't need recovery (since the
3178 kernel would have run the journal when the filesystem was mounted.)
3179 Also speed up e2fsck by avoiding unnecessary block group descriptor
3180 updates in ext2fs_close().
3182 Add support to chattr to migrate inodes from using direct/indirect
3185 Avoid corrupting the filesystem if there is an attempt to shrink a
3186 filesystem using resize2fs smaller than possible by making
3187 ext2fs_set_bmap() more careful not to delete the old block until the
3188 new block can be inserted. In addition, fix a bug in how the minimum
3189 size of the filesystem (plus a safety margin) is calculated, and
3190 modify resize2fs to refuse to shrink the filesystem below that minimum
3191 size without the force flag.
3193 Teach blkid to try to figure out DM device names using take advantage
3194 of information in sysfs when running on kernels (2.6.29 and later)
3195 which provide this information in /sys/block/dm-<N>/dm/name; this is
3196 much faster than scanning for the device number in /dev/mapper.
3198 Fix blkid to prefer /dev/mapper/<name> device names instead of the
3199 private /dev/dm-X names.
3201 Add an -a option to debugfs's close_filesys command which writes any
3202 changes to the superblock or block group descriptors to all of the
3203 backup superblock locations.
3205 Add support to the filefrag program to use the FIEMAP ioctl.
3207 Update Chinese translation from the Translation Project.
3209 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
3210 Launchpad Bug: #381854)
3212 Fixed various Debian packaging issues --- see debian/changelog for
3213 details. (Addresses Debian Bug #506064)
3219 Add test code to make sure e2fsck's problem.c doesn't have two problem
3220 codes assigned to duplicate values.
3222 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
3223 (Addresses Sourceforge Bug: #2780205)
3225 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
3226 function declaration for init_resource_track() and
3227 print_resource_track() when RESOURCE_TRACK is not defined.
3229 The test code which is used to build the tst_csum program has been
3230 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
3231 avoid compile problems caused by not having a prototype for
3232 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
3234 Update the config.guess and config.sub file to the latest from the
3235 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
3236 Debian Bug: #528330)
3238 Add a new function, ext2fs_extent_open2(), which behaves like
3239 pext2fs_extent_open(), but uses the user-supplied inode structure
3240 when opening an extent instead of reading the inode from disk.
3243 E2fsprogs 1.41.5 (April 23, 2009)
3244 =================================
3246 Fix a number of filesystem corruption bugs in resize2fs when growing
3247 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
3250 Debugfs can now set i_file_acl_high via the set_inodes_field command,
3251 and print a 64-bit file acl. This is useful for debugging filesystem
3252 corruptions where the high bits of i_file_acl_high are set. E2fsck
3253 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
3254 since some Linux kernel versions pay attention to this field even when
3257 Speed up e2fsck when checking clean filesystems by avoiding
3258 unnecessary block reads, and coalescing the block group descriptor
3259 blocks so they are read using a single read operation.
3261 The libuuid library will now close all file descriptors before running
3262 uuidd. This avoids problems when the calling program has open sockets
3263 which then never get closed because uuidd is a long-running helper
3264 daemon. (Addresses Launchpad bug: #305057)
3266 In order to avoid unnecessary full filesystem checks by e2fsck after
3267 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
3268 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
3270 Mke2fs will avoid trying to create the journal when run in
3271 superblock-only mode (mke2fs -S), since the left-over journal in the
3272 inode table will cause mke2fs to fail.
3274 Fix a bug in libext2fs functions that check to see if a particular
3275 device or filesystem image is mounted, which would cause these
3276 functions to report that a file identical to the (relative) pathname
3277 used by a pseudo-filesystem was mounted when in fact it was not.
3279 Update Czech translation from the Translation Project.
3281 Add Chinese (simplified) translation from the Translation Project.
3283 Fix support for external journals (which was broken in e2fsprogs
3286 Fix a regression in debugfs where the "stat" command when no
3287 filesystem was open would cause debugfs to crash with a segmentation
3290 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
3291 used to support filesystems without a journal. Update the blkid
3292 library so it understands this.
3294 The blkid library will remove an entry from the blkid cache
3295 representing the entire disk if partitions are found, since presumably
3296 the device previously had no partition table, but has now transitioned
3297 to using a partition table.
3299 Add a check to mke2fs and tune2fs that the argument to the -m option
3300 (which specifies the reserved ratio) must be greater than zero.
3301 (Addresses Debian Bug: #517015)
3303 Add support for tracking the number kilobytes written to the
3304 filesystem via the superblock field s_kbytes_written. It will be
3305 updated by the kernel as well as by e2fsprogs programs which write to
3306 the filesystem. This is useful for tracking the wear to filesystems
3307 on Solid State Drives.
3309 Fix compatibility issue in the libext2fs info file and makeinfo
3310 version 4.12. (Addresses Red Hat Bugzilla: #481620)
3312 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
3314 Fixed various Debian packaging issues --- see debian/changelog for
3315 details. (Addresses Debian Bug: #506279)
3320 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
3323 Fix various gcc compilation warnings and other programming cleanups.
3324 (Addresses Red Hat Bugzilla: #486997)
3326 Add support for building the blkid command statically.
3328 Add support for disabling the built-in blkid library in favor of a
3329 system-installed blkid implementation via the configure option
3333 E2fsprogs 1.41.4 (January 27, 2009)
3334 ===================================
3336 Fixed a bug which could sometimes cause blkid to return an exit value
3337 of zero for a non-existent device (Addresses Debian Bug: #502541)
3339 Blkid will now recognize ext3 filesystems that have the test_fs flag
3340 set as ext3 filesystems.
3342 The blkid library will now recognize btrfs filesystems and swap
3343 devices currently used by user-level software suspend.
3345 Tune2fs now updates the block group checksums when changing the UUID
3346 to avoid causing e2fsck to complain vociferously at the next reboot.
3348 Tune2fs's inode size resizing algorithms have been fixed so it is not
3349 vastly inefficient for moderate-to-large filesystems, due to some
3350 O(n**2) and O(n*m) algorithms that didn't scale well at all.
3352 Fix tune2fs's inode resizing algorithm so it will not corrupt
3353 filesystems laid out for RAID filesystems; in addition, tune2fs will
3354 refuse to change the inode size for filesystems that have the flex_bg
3355 feature enabled. (This is a limitation in the current implementation
3358 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
3359 filesystems with 32-bit block numbers, when the headers for 64-bit
3360 block numbers was added. This regression has been fixed.
3362 Debugfs's ncheck command has been fixed to avoid printing garbage
3363 characters at the end of file names.
3365 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
3366 when shrinking filesystems with uninit_bg feature would not be moved.
3367 In addition, blocks and inode table blocks were not being correctly
3368 freed when shrinking filesystems with the flex_bg feable, which caused
3369 resize2fs -M to fail. Finally, when blocks are moved, make sure the
3370 uninitialized flag in extents is preserved.
3372 Fix bug which caused dumpe2fs to abort with an error if run on a
3373 filesystem that contained an external journal.
3375 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
3376 for this in argv[0] to provide better legacy support for these
3377 distributions. This is a practice that should NOT be continued,
3380 Mke2fs now has a new option -U, which allows the user to specify the
3381 UUID that should be used for the new filesystem.
3383 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
3384 minus one block. This allows users who have read that ext3 supports
3385 up to 16TB filesystems and who create a 16TB LVM to not get confused,
3386 since the true limit is really 16TB minus one block.
3388 E2fsck will no longer abort an fsck run if block group has an errant
3391 E2fsck now distinguishes between fragmented directories and fragmented
3392 files in verbose mode statistics and in the fragcheck report.
3394 Fix a bug in e2fsck which caused it double count non-contiguous
3395 extent-based inodes.
3397 E2fsck will leave some slack space when repacking directories to allow
3398 room for a few directory entries to be added without causing leaf
3399 nodes to be split right away.
3401 Fix a bug which caused e2fsck to crash when it comes across a
3402 corrupted interior node in an extent tree with the error message:
3403 "Error1: Corrupt extent header on inode XXXXXX"
3405 E2fsck problem descriptions involving the journal are no longer
3406 referred to as "ext3" problems, since ext4 filesystems also have
3409 Fix a long-standing bug in e2fsck which would cause it to crash when
3410 replying journals for filesystems with block sizes greater than 8k.
3412 Update Catalan translation from the Translation Project.
3414 Fixed various Debian packaging issues --- see debian/changelog for
3415 details. (Addresses Debian Bugs: #503057, #502323, #511207)
3420 Fix build of e2fsck.profiled, and add support for building profiled
3421 binaries in the misc directory if configured with --enable-profile.
3423 The ext2fs_open() function now performs more sanity checks on the
3424 superblock to avoid potential divide by zero errors by other parts of
3427 The ext2fs_read_inode_full() function now has a safety check to avoid
3428 a segmentation fault on corrupted filesystems.
3430 The ext2fs_new_inode() function now has a sanity check so that if the
3431 s_first_inode field in the superblock is insane, it will return
3432 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
3434 To avoid segmentation faults, ext2fs_block_alloc_stats() and
3435 ext2fs_inode_alloc_stats() now validates the passed inode or block
3436 number to avoid overrunning an array boundary.
3438 Various signed/unsigned errors for variables containing block numbers
3441 Accommodations for gcc's stupidity in not realizing that constant
3442 strings that do not contain a '%' character are safe to use in format
3443 strings have been made so that distributions that want to compile
3444 e2fsprogs with -Werror=format-security have an easier time doing so.
3446 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
3448 Added the utility make-sparse.c to the contrib directory.
3450 The ext2fs_block_iterate2() function now reflects errors from
3451 ext2fs_extent_set_bmap() to the caller, if the callback tries to
3452 change a block on an extent-based file, and ext2fs_extent_set_bmap()
3453 fails for some reason (for example, there isn't enough disk space to
3454 split a node and expand the extent tree.
3456 The ext2fs_block_iterate2() function will preserve the uninit flag in
3457 extents when the callback function modifies a block in an extent-based
3460 E2fsck will now flag filesystems that have an insane s_first_ino field
3461 in their superblock, and attempt to use a backup superblock to repair
3465 E2fsprogs 1.41.3 (October 12, 2008)
3466 ===================================
3468 E2fsck has been fixed so it prints the correct inode number for
3469 uinit_bg related problems.
3471 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
3472 is available on linux. This can be disabled via a configuration
3473 option in /etc/e2fsck.conf.
3475 Fix a file descriptor leak in libblkid when checking to see if an ext4
3476 or ext4dev module exists.
3478 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
3479 while trying to close a filesystem can lead to infinite loops.
3480 (Addresses Red Hat Bugzilla #465679)
3482 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
3483 will cause resize2fs to drop into an infinite loop. (Addresses Red
3484 Hat Bugzilla: #465984)
3486 Add a check in the Unix I/O functions in libext2fs so that when a
3487 device is opened read/write, return an error if the device is
3488 read-only using the BLKROGET ioctl.
3490 Fix debugfs's ncheck command so that it prints all of the names of
3491 hardlinks in the same directory.
3493 Fix a bug in libblkid so it correctly detects whether the ext4 and
3494 ext4dev filesystems are available, so that the ext4dev->ext4
3495 fallback code works correctly.
3500 Fix a parallel build problem by making sure util/subst is built before
3501 trying to build the lib/et directory. (Addresses Sourceforge Bug:
3504 Updated "make depend" information for crc16.o
3507 E2fsprogs 1.41.2 (October 2, 2008)
3508 ==================================
3510 Fix e2fsck's automatic blocksize detection. This fixes a regression
3511 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
3512 specifies a block number using the -b option if the blocksize option
3513 isn't also specified using -B. Unfortunately, users very commonly
3514 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
3515 superblock; in fact e2fsck will often suggest this kind of command
3518 Enhance the debugfs's "ncheck" command so it will print all of the
3519 pathnames for the specified inodes. (Previously, in some cases ncheck
3520 might not print a pathname for an inode at all if some of the other
3521 inodes had multiple hard links.)
3523 Enhance debugfs's "hash" command so the hash seed can be specified via
3524 a command-line option. In addition, allow the hash algorithm to be
3525 specified by name instead of just by number.
3527 Fix e2fsck so that we don't accidentally print the translation file's
3528 header when asking the user a custom question so there is no prompt
3529 defined for a particular problem record. For example, the question
3530 "Run journal anyway" will get the PO header tacked on because e2fsck
3531 erroneously passed the null string to _(). (Addresses Launchpad Bug:

3569 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
3570 has been carrying a patch for a long time to prevent a largely
3571 theoretical race condition if a multi-threaded application adds and
3572 removes error tables in multiple threads. Unfortunately SuSE's

3612 E2fsprogs 1.41.1 (September 1, 2008)
3613 ====================================
3615 Many people are forgetting to update their mke2fs.conf file, and this
3616 causes ext3, ext4, and ext4dev filesystems won't get created with the
3617 proper features enabled. We address this in two ways. First, mke2fs
3618 will issue a warning if there is not definition for an ext3, ext4, or
3619 ext4dev filesystem and the user is trying to create such a filesystem
3620 type. Secondly, when installing from a source build, "make install"
3621 will provide basic configuration file handling for /etc/mke2fs.conf.
3622 If it exists, and does not mention ext4dev, it will be moved aside to
3623 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
3624 be installed. If the existing /etc/mke2fs.conf file does mention
3625 ext4dev, then "make install" will install official mke2fs.conf file as
3626 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
3627 they should look to see if any changes need to be merged.
3629 The mke2fs program will now create the journal in the middle of the
3630 filesystem, since this minimizes seek times on average for fsync-heavy
3631 workloads. In addition, mke2fs will now create journals using extents
3632 for filesystems that support them. This results in a more efficient
3633 encoding for the journal since it eliminates the need for using
3636 The mke2fs program will avoid allocating an extra block to the
3637 journal. (Addresses Sourceforge Bug: #1483791)
3639 Mke2fs will correctly enforce the prohibition against features
3640 (specifically read-only features) in revision 0 filesystems. (Thanks
3641 to Benno Schulenberg for noticing this problem.)
3643 Mke2fs previously would occasionally create some slightly non-optimally
3644 placed inode tables; this bug has been fixed.
3646 The mke2fs and tune2fs programs now print the correct usage message
3647 describing the maximum journal size. (Addresses Debian Bug: #491620)
3649 Add support for setting the default hash algorithm used in b-tree
3650 directories in tune2fs (from a command-line option) or mke2fs (via
3651 mke2fs.conf). In addition, change the default hash algorithm to
3652 half_md4, since it is faster and better.
3654 The blkid library will now recognize MacOS hfsx filesystems, and
3655 correctly extract the label and uuid for hfs, hfsx, and hfsplus
3656 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
3658 The blkid library has improved detection of JFS and HPFS filesystems.
3659 (Addresses Launchpad Bug: #255255)
3661 The blkid library is now much more efficiently handling devicemapper
3662 devices, mainly by no longer using the devicemapper library. This can
3663 speed up access for systems with a large number of device mapper
3666 Blkid had a number of cache validation bugs in libblkid that have been
3667 fixed. (Addresses Debian Bug: #493216)
3669 Resize2fs will now properly close out the "updating inode references"
3670 progress bar so there is a newline printed before printing the final
3671 "resize is successful" message.
3673 Resize2fs will now correctly handle filesystems with extents and/o
3674 uninitialized block groups correctly when file/directory blocks need
3675 to relocated (i.e., when shrinking a filesystem or if the resize_inode
3676 is not present). To support this, the ext2fs library now supports
3677 initializing inode and block bitmaps that are not yet initialized when
3678 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
3679 addition, e2fs_block_iterate2() can now support changing the location
3680 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
3681 been optimized to avoid creating unnecessary new extents when updating
3682 the location of blocks in the extent tree. This will also help out
3683 e2fsck's recovery of obscurely corrupted filesystems with extents,
3684 when blocks are claimed by multiple inodes.
3686 Add support for on-line resizing ext4 filesystem with the flex_bg
3687 filesystem feature. The method for doing so is not optimal, but to do
3688 a better job will require kernel support.
3690 E2fsprogs 1.41.0 introduced a bug in libext2fs which caused e2image and
3691 debugfs programs to not be able to read e2image files; the signed
3692 vs. unsigned bug in the code which read bitmaps from the e2image has
3693 been fixed. (Addresses Debian Bug: #495830)
3695 Resize2fs is now correctly managing the directory in-use counts when
3696 shrinking filesystems and directory inodes needed to be moved from one
3697 block group to another. This bug has been around since e2fsprogs
3698 1.26, and is largely harmless, but does cause a filesystem corruption
3699 which will be flagged by e2fsck after the filesystem has been shrunk.
3701 E2fsck will no longer issue spurious complaints about the inode size
3702 caused by very large extent-based files, and by blocks reallocated
3703 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
3704 Kernel Bugzilla: #11341)
3706 Mke2fs will now set the creation timestamp on the lost+found directory
3707 and the root directory. (More generally, all new inodes created using
3708 the ext2fs library will correctly set the creation timestamp.)
3710 E2fsck now correctly calculates ind/dind/tind statistics in the
3711 presence of extent-based files. In addition, "e2fsck -v" will report
3712 statistics of the depth of extent trees in the filesystem. E2fsck can
3713 also give an inode fragmentation report using "e2fsck -E fragcheck"
3714 which can be useful when debugging the kernel block allocation
3717 Fix support for empty directory blocks in ext4 filesystems with 64k
3718 blocksize filesystems.
3720 E2fsck will now print the depth of corrupt htree directories.
3722 Debugfs's htree command now correctly understands extent-based
3723 directories. It will also print out the minor hash as well as the
3726 Debugfs has a new command which will print the supported features of
3727 e2fsprogs, to enable scripts to know whether the installed version of
3728 e2fsprogs can support a specific feature.
3730 Debugfs will now write files using extents for filesystems that
3733 The error message printed by "tune2fs -I" if the inode size was too
3734 small was rather confusing, so it has been improved. Also, we won't
3735 try to create an undo log until we know that command-line-specified
3736 parameters such as "tune2fs -I <inode size>" are valid.
3738 Given some filesystems found "in the wild" that had non-zero block
3739 group checksums even though the uninit_bg/gdt_sum feature was not
3740 enabled, e2fsck would issue spurious error messages. Teach
3741 ext2fs_group_desc_csum_verify() to ignore the block group checksum
3742 entirely if the feature flag is not set. (Addresses Debian Bug:
3745 The blkid program will now print out a user-friendly listing of all of
3746 the block devices in the system and what they contain when given the
3747 -L option. (Addresses Debian Bug: #490527)
3749 The filefrag program now has a more accurate calculation for the
3750 number of ideal extents. (Addresses Debian Bug: #458306)
3752 The test I/O manager is now enabled by default, but its overhead is
3753 only incurred when it would be enabled via the TEST_IO_FLAGS or
3754 TEST_IO_BLOCK environment variables.
3756 Typographical errors in various program strings and usage messages
3757 have been fixed; most of these were pointed out by the e2fsprogs
3758 message catalog translators. (Thanks, translators!)
3760 Update and clarified various man pages, as well as some typographical
3761 errors in the libext2fs texinfo file.
3763 Fixed various Debian packaging issues --- see debian/changelog for

3774 don't have nanosleep(), try using usleep() instead.
3776 The "make check" target in the e2fsck directory now sets
3777 LD_LIBRARY_PATH before running the various e2fsck internal library
3780 The crc32 regression test in the e2fsck library is now portable to
3781 greater variety of environments, including big-endian systems and
3782 when cross-building e2fsprogs for embedded systems. (Addresses
3783 Sourceforge Bug: #2019287)
3785 The ext2fs_extent_set_bmap() had some bugs when setting the first
3786 block in a file, or when replacing a single block extent. Those cases
3787 fortunately were came up relatively rarely when e2fsck was checking
3788 files, but caused some problems when resize2fs was shrinking
3791 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
3794 Various ext2fs library functions --- ext2fs_block_iterate2(),
3795 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
3796 allocated memory to avoid memory leaks in all of their error return
3799 Ext2ed was failing to build because masix support had been removed in
3800 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
3802 The configure script now respects the LDFLAGS environment variable if
3803 it is set when configure is called. (Addresses Sourceforge Feature
3806 Libuuid is now more portable to the Windows platform. (Addresses
3807 Sourceforge Feature Request: #1937287)
3809 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
3810 bare echo commands so that configure flags such as --quiet work
3811 correctly. (Addresses Sourceforge Patches: #2058794)
3813 A few uses of sprintf have been removed from the ext2fs library to
3814 make life easier for bootloaders with a limited libc environment.
3815 (Addresses Sourceforge Bug: #2049120)
3817 The ext2fs_read_inode() checks the validity of the inode number passed
3818 to it earlier, to avoid doing some needless work when it would fail

3822 passed to it earlier, to avoid doing some needless work when it would
3825 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
3826 top-level Makefile. That automatic rule is used to better support
3827 SCCS, but it caused problems for a particular niche distribution which
3828 likes to use configure.sh files to store the configure options used to
3829 build a package. Unfortunately GNU make will use the configure.sh to
3830 replace the configure script, resulting in a self-inflicted fork bomb
3831 leading to an out-of-memory crash.
3833 To support old GNU C compilers don't use C99/C++ comments, but only
3834 K&R style comments, and don't try to use __builtin_expect if __GNUC__
3835 is less than 3. (__builtin_expect is only supported for gcc versions
3836 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
3837 this is an optimization, we only try to use __builtin_expect for gcc 3
3840 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
3841 __LITTLE_ENDIAN, which are only defined by glibc's header files and
3842 hence isn't portable.
3844 For the convenience for some distributions that need a static tune2fs,
3845 the Makefile for misc/ now has a tune2fs.static target.
3847 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
3848 for extent-based files
3850 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
3853 All source files no longer have any trailing white space.
3855 The io_channel_read_blk64() and io_channel_write_blk64() functions are
3856 now functions instead of C preprocessor macros to provide better
3857 forward compatibility.

3861 Various namespace leakages in libblkid, libe2p, and libext2fs have
3864 Fix a parallel build problem in e2fsprogs.
3866 E2fsprogs is now more portable to Solaris.
3867 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
3869 * Scripts do not assume that /bin/true is always in /bin
3870 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
3871 * Flush stdio handles before calling setbuf(), since Solaris will
3872 discard any pending output to the stream.
3873 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
3874 picky about which C compiler can be used for SUSv3 conformance.
3875 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
3876 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
3877 Since we need some SUSv3 functions, consistently use SUSv3 so
3878 that e2fsprogs will build on Solaris using c99.
3879 * Solaris C99 does not support varargs C preprocessor macros
3880 * Solaris header files pollute the C namespace if in/netinet.h
3881 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
3883 * Solaris ships with a pathetically ancient shell in /bin/sh so we
3884 avoid the use of various more advanced shell constructs such as $().
3886 The "make rpm" command will now take some extra configure options from
3887 the build environment without needing to patch the source tree.
3889 The ext2fs_add_dir_block() function will now grow the dblist more
3890 aggressively as an optimization to avoid copying the array too often.
3892 The e2fsck_write_bitmaps() will write the block and inode bitmaps
3893 together instead of in two passes.
3896 E2fsprogs 1.41 (July 10, 2008)
3897 ==============================
3899 Add support for ext4 filesystem features, in particular extents,
3900 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
3901 support for checking journal checksums. Debugfs will print new
3902 superblock and inode fields that were defined for ext4. For example,
3903 the nanosecond and i_version fields of an inode, and the
3904 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
3905 Note: Resize2fs doesn't currently support the combination of flex_bg
3906 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
3908 Tune2fs can support migrating a filesystem from using 128 byte inodes
3909 to 256 byte inodes, so it can take advantage of the full features of
3912 Add support for "undo" support. E2fsck and mke2fs can optionally
3913 record an undo log which can replayed by the program e2undo.
3915 E2fsck could damage a filesystem by trying to relocate inode tables
3916 due to corrupted block group descriptors, where the attempted inode
3917 table relocation would do far more harm than good. E2fsck has been
3918 fixed to detect this these sorts of corrupted block group descriptors
3919 much earlier in e2fsck processing, so it can try to use the backup
3920 superblock and block group descriptors first. This should be a much
3921 better strategy for recovering these types of corrupted filesystems.
3922 (Addresses Sourceforge Bug: #1840291)
3924 E2fsck will display a more understandable message when the last check
3925 field in the superblock is in the future. (Addresses Debian Bug:
3928 E2fsck now performs more extensive and careful checks of extended
3929 attributes stored in the inode.
3931 Enhance mke2fs to print a more explanatory error message when
3932 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
3935 Fix mke2fs to use a default block size of 4k when formatting an
3936 external journal device. This is done by using a fixed filesystem
3937 type list that consists only of the single filesystem type "journal"
3938 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
3939 Debian Bug: #488663)
3941 Speed up how mke2fs writes the journal data blocks by writing the disk
3942 blocks in larger chunks.
3944 Fix blkid handling of stale devices. Fix a bug which could cause a
3945 core dump while garbage collecting the blkid cache, and assure that
3946 blkid_find_dev_with_tag() never returns a non-existent device. Also,
3947 if a filesystem is found at a new /dev location, eliminate any
3948 duplicate stale entries which can not be verified.
3949 (Addresses Debian Bugs: #487758, #487783)
3951 Add more paranoid checks for LVM volumes and swap partitions in
3952 blkid's probe function, to reduce the chances of false positives.
3954 The mke2fs program now has a much more sophisticated system for
3955 controlling configuration parameters of a newly created filesystem
3956 based on a split filesystem and usage type system. The -t option to
3957 mke2fs was a deprecated alias to -c; it now specifies a filesystem
3958 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
3959 separated usage list. The filesystem type information and type
3960 information is used to extract configuration parameters from the
3961 /etc/mke2fs.conf file.
3963 The mke2fs program will no longer complain and request the -f option
3964 when the user tries to create a filesystem with greater than 2**31
3967 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
3968 adjust the mke2fs.conf file so filesystems for the Hurd are created
3969 with a blocksize of 4096 and inode size of 128, which is all it knows
3970 how to handle. (Addresses Debian Bug: #471977)
3972 Mke2fs will always make sure that lost+found always has at least 2
3973 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
3975 Resize2fs will now print the minimum needed filesystem size if given
3976 the -P option, and will resize the filesystem to the smallest possible
3977 size if given the -M option.
3979 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
3980 blocks are consumed during an off-line resize.
3982 The "ls" command in debugfs now supports the -p option, which causes
3983 it to quote the filenames so that spaces or tabs in directory entries
3984 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
3985 Sourceforge Feature Request: #1201667)
3987 Fix a potential off-by-one buffer overflow in the fs_device_name in an
3990 The chattr program will return a non-zero exit code in case of
3991 failures, and error messages can be suppressed with the -f option.
3992 (Addresses Red Hat Bugzilla: #180596)
3994 Fix a bug in badblocks which caused it to overrun an array and likely
3995 crash if more than 8 test patterns are specified using the -t option.
3996 (Addresses Debian Bug: #487298)
3998 Add support to badblocks to limit how quickly it reads from the disk
3999 drive (so it can be used for background scrubbing), and so it will
4000 abort after finding a given number of errors.
4002 Remove support for the legacy big-endian filesystem format which only
4003 existed on extremely long-dead PowerPC kernels almost a decade ago.
4005 Remove MASIX support from e2fsprogs.
4007 Add I/O statistics reporting to e2fsck.
4009 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
4012 Fixed various Debian packaging issues --- see debian/changelog for
4013 details. (Addresses Debian Bugs: #487443, #487675, #490003)

4034 Clean up the badblocks group so to make it more portable and robust.
4036 Avoid using predictable filenames in /tmp in blkid's regression test
4037 suite. Also remove bashism's in the regression test script.
4039 If the configure script is given --with-diet-libc, don't use thread
4040 local storage, since diet libc doesn't support TLS. (Addresses
4041 Sourceforge Bug: #2000654)
4043 Fix the blkid regression test suite to tolerate older versions of
4044 mkswap that don't support the -U option.
4046 A few library routines have been converted to support 64-bit block
4047 numbers; in particular, the I/O manager functions, the test_io,
4048 inode_io, and unix_io managers have all be converted to support 64-bit
4051 Debugfs can now be extended for use by test programs. See
4052 lib/ext2fs/extents.c for an example for how it can be used. The test
4053 program links against the debugfs object files, and provides
4054 additional commands by defining an auxiliary libss command table.
4056 The lazy_bg filesystem feature, which was only used by developer's
4057 testing, has been removed since it has been largely supplanted by
4058 uninit_bg. This also simplifies the code.
4061 E2fsprogs 1.40.11 (June 17, 2008)
4062 =================================
4064 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
4065 percentage of reserved blocks. (Addresses Debian Bug: #452639)
4067 Updated Spanish and Catalan translations.
4069 Fixed various Debian packaging issues --- see debian/changelog for
4070 details. (Addresses Debian Bugs: #483962, #483023)

4080 Fix marginal C code in probe_lvm2() function to the blkid library more
4081 portable for older compilers.
4083 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
4085 Fix ext2fs_swap{16,32,64} functions so they can be used by external
4086 applications on big-endian machines. (Addresses Debian Bug: #484879)
4089 E2fsprogs 1.40.10 (May 21, 2008)
4090 ================================
4092 When deciding whether or not to revalidate a blkid cache entry, if the
4093 device's mtime is newer than the last time the cached entry was
4094 validated, force a revalidation.
4096 Fix a potential data corruption bug in e2fsck in the journal replay.
4097 The chances of this is happening is extremely remote, especially the
4098 default data=ordered or data=writeback modes. However, if a block
4099 which has been journalled starts with the first four bytes 0xc03b3998,
4100 when e2fsck replays the journal, those four bytes will be replaced
4101 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
4102 metadata to begin with those fatal 4 byte sequence, and unless
4103 data=ordered mode is in use, data blocks are never journalled.
4105 Updated German, Dutch, Swedish, and Vietnamese translations.
4110 Fixed various Debian packaging issues --- see debian/changelog for
4113 Remove default sizes of types when cross compiling, since autoconf
4114 2.50 can figure this out automatically now.
4117 E2fsprogs 1.40.9 (April 27, 2008)
4118 =================================
4120 SuSE's security team audited uuidd and came up with a few minor
4121 issues. None of them are serious given that uuidd runs setuid as a
4122 unprivileged user which has no special access other than libuuid
4123 directory, but it's good to get them fixed.
4125 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
4126 work correctly with in-inode extended attributes.
4128 Updated German, Czech, Dutch, French, Polish, Swedish, and Vietnamese
4131 Debugfs will avoid using a pager if the standard output is not a tty.
4133 Fix debugfs and tune2fs to correctly handle daylight savings time when
4134 parsing a time string.
4136 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4138 Fix fsck completion bars when multiple filesystems were being checked
4139 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
4140 #203323, Addresses Sourceforge Bug: #1926023)
4142 Fix fsck so that progress information is sent back correctly when
4143 multiple filesystems are being check and the output of fsck is being
4144 redirected to a file descriptor. Also, include the device name (w/o
4145 spaces) in the progress information sent back via a file descriptor.

4149 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
4151 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
4152 signal to its child process.
4154 Fix mke2fs's creation of are resize inode when there is a non-standard
4155 s_first_data_block setting.
4157 Fix bug in blkid when run by an unprivileged user; most devices were
4158 not reported correctly. 9Addresses Launchpad Bug: #220275)
4160 Mke2fs will not allow the logically incorrect combination of
4161 resize_inode and meta_bg, which had previously caused mke2fs to create
4162 a corrupt filesystem.
4164 Fix fsck in German locales so that a 'j' means yes.

4171 Fixed various Debian packaging issues --- see debian/changelog for
4174 Update valgrind options in test_script to work with valgrind 3.2.3

4184 (harmless) error message.
4187 E2fsprogs 1.40.8 (March 13, 2008)
4188 =================================
4190 Fixed e2image -I so it works on image files which are larger than 2GB.
4192 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
4193 the size is larger than the number of blocks found in the inode, don't
4194 try to allocate extra empty blocks at the end of the directory to make
4195 up the difference; there's no point to doing that. In addition, if
4196 the size is not a multiple of a blocksize, always fix it.
4198 E2fsck handled a pass 2 "should never happen error" by not giving
4199 enough information and then core dumping. Unfortunately, it was all
4200 too easy to trigger the "should never happen" situation if a
4201 directory's inode size was not correct. This has been fixed, but
4202 e2fsck has also been taught how to handle this situation more
4203 gracefully, by simply removing the inode hash tree information, so
4204 that it can be rebuilt again after e2fsck's pass 3. (Addresses
4205 Launchpad Bug: #129395)
4207 Resize2fs had a bug resizing large inodes with extended attributes
4208 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
4209 completely on big-endian systems such as PowerPC. The bug should be
4210 completely fixed now. Yay for regression test suites. (Addresses Red
4211 Hat Bugzilla: #434893)

4216 Bugs: #302512, #370247, #401092, #412882).
4218 When e2fsck is clearing a corrupt inode's HTREE directory information,
4219 make it clear that it is just clearing the HTREE information, not the
4222 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4227 Add new functions, ext2fs_dblist_get_last() and
4228 ext2fs_dblist_drop_last(), which allows the caller to examine the last
4229 directory block entry added to the list, and to drop if it necessary.
4231 Fixed a portability problem in libblkid with DJGPP.
4233 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
4234 to Philipp Thomas for pointing this out.
4236 If the info files are not built, change "make install" so it doesn't
4237 fail with an error code.
4240 E2fsprogs 1.40.7 (February 28, 2008)
4241 ====================================
4243 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
4244 depreciate the -s option, since it can result in filesystems which
4245 e2fsck can't fix easily. There are very good reasons for wanting to
4246 disable sparse_super; users who wants to turn off sparse_super can use
4247 debugfs. (Addresses Sourceforge Bug: #1840286)
4249 Add missing options to mke2fs's usage message. (Addresses Sourceforge
4252 Fix bug in resize2fs when large (greater than 128 byte) inodes are
4253 moved when a filesystem is shrunk; it was only moving the first 128
4254 bytes, so extended attributes were not getting moved. (Addresses Red
4255 Hat Bugzilla: #434893)
4257 E2fsck now prints an explicit message when the bad block inode is
4258 updated, to avoid confusion about why the filesystem was modified.
4259 (Addresses Sourceforge Bug: #756460)
4261 Allow mke2fs and tune2fs manipulate the large_file feature.
4262 Previously we just let the kernel and e2fsck do this automatically,
4263 but e2fsck will no longer automatically clear the large_file feature.
4264 It still isn't really necessary to worry about this feature flag
4265 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
4268 Suppress message about an old-style fstab if the fstab file is empty.
4269 (Addresses Debian Bug: #468176)
4271 Fix (really minor) bug in debugfs's find_free_block so it avoids
4272 reporting a free block more than once if there are too few free blocks
4273 in the filesystem. (Addresses Sourceforge Bug: #1096315)
4275 Change e2fsck to no longer clear the LARGE_FILES feature flag
4276 automatically, when there are no more > 2GB files in the filesystem.
4277 It's been almost a decade since there have been kernels that don't
4278 support this flag, and e2fsck clears it quietly without telling the
4279 user why the filesystem has been changed.
4281 Fix bug which could cause libblkid to seg fault if a device mapper
4282 volume disappears while it is being probed. (Addresses RedHat
4285 Enhance e2fsck's reporting of unsupported filesystem feature flags.
4286 (Addresses Sourceforge Feature Request: #1175808)
4288 Fix option syntax in dumpe2fs for explicit superblock and blocksize
4289 parameters. What was currently documented in the man page has been
4290 broken for some time, due to getopt() implementation changes. The
4291 option syntax has been changed to one which is can be more portable
4292 supported and which is consistent with the format for extended options
4293 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
4295 Add support to tune2fs to clear the resize_inode feature. This
4296 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
4298 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
4301 Add support for setting RAID stride and stripe-width via mke2fs and
4302 tune2fs. Teach dumpe2fs to print the RAID parameters.
4304 Add support for setting new superblock fields to debugfs's
4307 Add support for printing "mostly-printable" extended attributes in
4310 Add support for the -M option to fsck, which causes it to ignore

4327 Fixed various Debian packaging issues --- see debian/changelog for
4328 details. (Addresses Debian Bug: #466929)
4330 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
4331 partially filled-in filesystem object on an error, so that e2fsck can
4332 print more intelligent error messages.
4334 Add a new function e2p_edit_feature2() which allows the caller to
4335 specify which feature flags are OK to set or clear, and which returns
4336 more specific information about feature flags which are not allowed to
4339 Set the C locale in the test_script driver since it uses [A-Za-z].

4342 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't

4346 absolutely needed. (i.e., when using parsing a WIP-style version
4347 number) (Addresses Sourceforge Bug: #1893024)
4349 Add portability checks to support compilation under DJGPP.
4351 Update to the latest samba tdb code before the LGPLv3 change, which

4363 ===================================
4365 Add support for returning labels for UDF filesystems in the blkid
4368 Fix bug in the blkid library where cached filesystems was not being
4369 flushed when opening USB devices returned the error ENOMEDIUM.
4370 (Addresses Debian Bug: #463787)
4372 Added logic to the blkid library to automatically choose whether a
4373 filesystem should be mounted as ext4 or ext4dev, as appropriate.
4375 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
4377 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
4378 configured with --enable-jbd-debug.
4380 Document the BLKID_FILE environment variable in the libblkid man page
4385 Update e2fsprogs translation template and Vietnamese and Czech translations
4387 Fixed various Debian packaging issues --- see debian/changelog for
4388 details. (Addresses Debian Bugs: #436058)
4390 Don't try to create $DESTDIR/etc/init.d as part of make install as we
4391 don't install the init.d script (and it's not the recommended way to
4392 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
4394 Use thread local storage to fix a theoretical race condition if two
4395 threads try to format an unknown error code at the same time in the
4399 E2fsprogs 1.40.5 (January 27, 2008)
4400 ===================================
4402 Fix a potential overflow big in e2image if the device name is too
4405 Mke2fs will now create new filesystems with 256 byte inodes and the
4406 ext_attr feature flag by default. This allows for much better future
4407 compatibility with ext4 and speeds up extended attributes even on ext3
4410 Teach e2fsck to ignore certain "safe" filesystem features which are
4411 set automatically by the kernel. Having the kernel set features
4412 automagically behind the user's back is a bad idea, and we should try
4413 to break the kernel of this habit, especially for the newer ext4
4414 feature flags. But for now, we will try to avoid needless full checks
4415 which can annoy users who are doing fresh installs.
4417 Add support in tune2fs and mke2fs for making a filesystem as being "ok
4418 to be used with test kernel code". This will be needed for using test
4419 filesystems with the latest ext4 kernel code.
4421 Change e2fsck -fD so that it sorts non-htree directories by inode
4422 numbers instead of by name, since that optimizes performances much
4423 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
4425 If e2image fills the disk, fix it so it exits right away instead of
4426 spewing large numbers of error messages.
4427 (Addresses-Sourceforge-Feature-Request: #606508)
4429 If ftruncate64() is not available for resize2fs, let it use ftrucate()
4430 instead, but have it check to see if the size would get truncated, and
4431 skip calling ftruncate in that case.
4433 Add support for detecting HFS+ filesystems in the blkid library.
4435 Add support in the blkid library for ext4/ext4dev filesystems.
4437 Fix a bug in blkid where it could die on a floating point exception
4438 when presented with a corrupt reiserfs image.
4440 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
4441 such that UUID string is a fixed length.
4443 Add sample python bindings for the uuid library to the contrib
4444 directory. (Addresses-Sourceforge-Patches: #778817)
4446 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
4447 will work with large files. (Addresses Sourceforge Feature Request:
4448 #1257500 and Sourceforge Support Request: #1253511)
4450 Allow the debugfs 'undel' command to undelete an inode without linking
4451 it to a specific destination directory, since this might require
4452 allocating blocks that could overwrite some yet-to-be-recovered
4453 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
4455 Update Swedish translation from the Translation Project.

4489 ====================================
4491 Improve time-based UUID generation. A new daemon uuidd, is started
4492 automatically by libuuid if necessary. This daemon is setuid to allow
4493 updates to /var/lib/libuuid, so the clock sequence number can be
4494 stored and so if the clock is set backwards, it can be detected.
4495 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
4498 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
4499 superblocks. This avoids e2fsck from concluding that a full
4500 filesystem check is required before backing up the superblock due to
4501 changes in the feature flags. (Addresses Debian Bug: #454926)
4503 Fix fsck to only treat the '#' character as a comment at the beginning
4504 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
4505 will cause fsck to issue an bogus warning message.
4506 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
4508 Format control characters and characters with the high eighth bit set
4509 when printing the contents of the blkid cache, to prevent filesystems
4510 with garbage labels from sending escape sequences to the user's screen

4514 Fix sign-extension problem on 64-bit systems in in the com_err
4515 library. (Addresses Sourceforge Bug: #1809658)
4517 Avoid division by zero error when probing an invalid FAT filesystem in
4518 the blkid library. (Addresses Sourceforge Bug: #1831627)
4520 Update Dutch, Polish, and Vietnamese translations from the Translation
4521 Project. Remove the Rwandan translation upon advice of the
4522 Translation Project.
4527 Fix the libss "make check" regression test so that it works if the
4528 current directory is not in the user's path or if the libss shared
4529 library is not installed. (Addresses Sourceforge Bug: #1848974)

4543 E2fsprogs 1.40.3 (December 5, 2007)
4544 ===================================
4546 Fix a potential security vulnerability where an untrusted filesystem
4547 can be corrupted in such a way that a program using libext2fs will
4548 allocate a buffer which is far too small. This can lead to either a
4549 crash or potentially a heap-based buffer overflow crash. No known
4550 exploits exist, but main concern is where an untrusted user who
4551 possesses privileged access in a guest Xen environment could corrupt a
4552 filesystem which is then accessed by the pygrub program, running as
4553 root in the dom0 host environment, thus allowing the untrusted user to
4554 gain privileged access in the host OS. Thanks to the McAfee AVERT
4555 Research group for reporting this issue. (Addresses CVE-2007-5497.)
4557 Fix heuristics in blkid which could cause a disk without partitions to
4558 be incorrectly skipped when a loopback device is present. (Addresses
4559 Red Hat Bugzilla #400321.)
4561 Fix e2image so that in raw mode it does not create an image file which
4562 is one byte too large.
4564 Change mke2fs's usage message so it recommends the preferred -E option
4565 instead of the deprecated -R option.
4567 Enhance the blkid library so it will recognize squashfs filesystems.
4568 (Addresses Red Hat Bugzilla #305151.)
4570 Enhance e2fsck so it will force the backup superblocks to be backed up
4571 if the filesystem is consistent and key constants have been changed
4572 (i.e., by an on-line resize) or by e2fsck in the course of its
4575 Enhance blkid's detection of FAT filesystems; so that USB disks with
4576 only a single bootable partition will not get missed.
4578 E2fsck will no longer mark a filesystem as invalid if it has time
4579 errors (i.e., if superblock mount time or last write time is in the
4580 future) and the user refuses to fix the problem.
4582 The Ubuntu init scripts don't properly set the system time correctly
4583 from hardware clock if the hardware clock is configured to tick local
4584 time instead of GMT time. Work around this as best as we can by
4585 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
4586 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
4589 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
4590 Hat Bugzilla #151533.)
4592 Fix e2fsck so that if the superblock is corrupt, but still looks
4593 vaguely like an ext2/3/4 superblock, that it automatically tries to
4594 fall back to the backup superblock, instead of failing with a hard
4597 Make the e2fsprogs program more robust so that they will not crash
4598 when opening a corrupt filesystem where s_inode_size is zero.
4600 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
4601 arguments are detected as such and the parse error is reported to the
4602 user. (Addresses Debian Bug #435381.)
4604 Change e2fsck so it will not complain if a file has blocks reallocated
4605 up to the next multiple of a system's page size.
4607 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
4608 about (valid) filesystems where the inode table extends to the last
4609 block of the block group. (Addresses Red Hat Bugzilla #214765.)
4611 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
4612 allocating inode tables for some relatively rare odd disk sizes.
4613 (Addresses Red Hat Bugzilla #241767.)
4615 Add Catalan translation and update Dutch and Swedish translations
4616 from the Translation Project.
4618 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
4619 still had an issue when trying to figure out whether we need to
4620 byte-swap fast symlinks that contained extended attributes.
4622 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4623 (Addresses SourceForge Bug #1821333.)
4629 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
4631 Add "make check" to the RPM spec file
4633 Fix "make install" and 'make uninstall" in misc/Makefile.in so that it
4634 works correctly when the prefix is not the root directory.
4636 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
4637 clean up after themselves by deleting the test.img temporary file
4638 after completing the test.
4640 Fixed a corner case bug ext2fs_unlink() when trying to delete the
4641 first directory entry in a directory block and the last directory
4642 entry in the previous directory block is not in use. Fortunately
4643 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
4644 places where it is extremely unlikely to run into this corner case.
4646 Fix missing dependency which would cause parallel builds to fail.
4647 (Addresses Sourceforge Bug #1842331.)
4649 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
4650 calling open(O_CREATE) with a missing mode parameter.
4652 Fix the test_ss.c in lib/ss so it can be used as an example
4653 application program for the library as well as a regression test
4656 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
4657 are properly passed back up through the call stack.
4659 E2fsprogs 1.40.2 (July 12, 2007)
4660 ================================
4662 A recent change to e2fsck_add_dir_info() to use tdb files to check
4663 filesystems with a very large number of filesystems had a typo which
4664 caused us to resize the wrong data structure. This would cause a
4665 array overrun leading to malloc pointer corruptions and segfaults.
4666 Since we normally can very accurately predict how big the the dirinfo
4667 array needs to be, this bug only got triggered on very badly corrupted
4670 Fix a bug in e2fsck which caused it to incorrectly salvage
4671 directories when the last entry's rec_len is bogusly too big. This
4672 resulted in a nonsense filesystem corruption to be reported, and
4673 required a second run of e2fsck to fully fix up the directory.
4675 Update tune2fs man page to include more discussion of reserved blocks
4676 (Addresses Launchpad bug #47817)
4678 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
4682 E2fsprogs 1.40.1 (July 7, 2007)
4683 ===============================
4685 Fix bug which could cause libblkid to loop forever. When revalidating
4686 a partition where there is obsolete information in /etc/blkid.tab, we
4687 end up freeing a the type tag without clearing dev->bid_type, causing
4688 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
4690 The Turkish translation has a bug in it where it has the translation
4691 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
4692 @E, recursively, forever, until the stack fills up and e2fsck core
4693 dumps. We fix this by making e2fsck stop @-expansions after a
4694 recursive depth of 10, which is far more than we need.
4695 (Addresses Sourceforge Bug: #1646081)
4697 Compile the default mke2fs.conf into mke2fs program. People are
4698 getting surprised by mke2fs creating filesystems with different
4699 defaults than earlier versions of mke2fs if mke2fs.conf is not
4700 present. So we now create a built in version of mke2fs.conf file
4701 which is used by mke2fs if the /etc/mke2fs.conf is not present.
4702 (Addresses SourceforgeBug: #1745818)
4704 Improve the config/parse_types.sh helper script. Fix a potential
4705 security problem if e2fsprogs is built as root (as Gentoo does!). In
4706 addition fix the script and how it is called from the configure script
4707 so that it does the right thing when cross-compiling. (Fixes Gentoo
4710 Update Vietnamese, French, and Dutch PO files from the Translation
4711 Project. Also created a new e2fsprogs.pot file for translator.
4713 Fix bogus strip permission errors when building under Debian. When
4714 building the e2fsprogs dpkg's, the dh_strip command emits a large
4715 number of error messages caused by the permissions not being right.
4716 So run dh_fixperms before running dh_strip.
4721 Add new function: profile_set_default(). This function sets the value
4722 of the pseudo file "<default>". If the file "<default>" had
4723 previously been passed to profile_init(), then def_string parameter
4724 will be parsed and used as the profile information for the "<default>"
4727 Fix mk_cmds's error reporting so that it is unambiguous that it is the
4728 mk_cmds script which is generating the error. (Obviates Gentoo patch:
4729 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
4731 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
4732 priority" environment variable that overrides all others, where as
4733 LANG is the lowest priority environment variable. If LC_ALL is set, it
4734 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
4735 the all the rest are set. This will assure that the locale when
4736 running the test suites is the "C" locale. (Obviates Gentoo patch:

4741 ==============================
4743 Fix divide by zero error in blkid's NTFS probing logic.
4745 Add new blkid -g option which causes the blkid cache to be garbage
4748 Fix a bug in libblkid which could cause the internal field bid_type to
4749 become corrupted. Fortunately bid_type isn't used much, and bid_label
4750 and bid_uuid is only used by debugging code, so the impact of this bug

4754 created with a requested RAID stride, and then use it automatically in
4757 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
4758 isn't too big. In some cases Lustre users have tried specifying an
4759 inode size of 4096 bytes, while keeping an inode ratio of one inode
4762 Improve sanity check in e2fsck's algorithm for finding a backup
4763 superblock, so that it won't accidentally find a superblock that was
4764 located in the journal, and then later reject it as being not a valid
4767 Fix e2fsck get_size logic so that it will work with the Linux floppy
4768 driver. The Linux floppy driver is a bit different from the other
4769 block device drivers, in that if the device has been opened with
4770 O_EXCL, it disallows another open(), even if the second open() does
4771 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
4773 Fix error checking of badblock's last-block and start-block arguments.

4793 the backup journal information from the superblock was successfully
4794 used to recover the filesystem.
4796 Fix e2fsck so that it checks all of the blocks in the journal inode
4797 for validity. The original code only checked the direct blocks to
4798 make sure the journal inode was sane. Unfortunately, if some or all
4799 of the indirect or doubly indirect blocks were corrupted, this would
4802 Add support in blkid to detect LUKS encrypted partitions.
4804 Add extra sanity checks for extended attributes in the case where the
4805 size is zero but the offset is very large.
4807 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
4808 and ext2fs_get_next_inode_full().
4810 Clarify the copyright licenses used by the various libraries in
4811 the top-level COPYING file (Red Hat Bugzilla: 166058)
4813 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
4815 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
4817 Remove check in e2fsck which requires EA's in inodes to be sorted;
4818 they don't need to be sorted, and e2fsck was previously wrongly
4819 clearing unsorted EA's stored in the inode structure.
4821 Allow mke2fs or tune2fs to create a substantially larger journal (up
4822 to 10,240,000 blocks).
4824 Fix MD superblock detection, and make sure the correct UUID is
4825 reported from the MD superblock.
4827 Fix a signed vs. unsigned bug in debugfs.
4829 Enhance debugfs's date parser so that it accepts integer values.
4831 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
4832 file with multiply claimed blocks is hard linked. or not at all if the
4833 root directory contains shared blocks
4835 Enhance debugfs so it can modify the block group descriptors using the
4836 command set_block_group_descriptor.
4838 Improve e2fsck's reporting of I/O errors so it's clearer what it was
4839 trying to do when an error happens
4841 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
4842 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
4843 #232663 and LTC Bugzilla: #27634)

4856 Allow the debugfs lcd command to work w/o a filesystem being open.
4857 (Addresses LTC Bugzilla #27513)
4859 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
4860 field on the first pass.
4862 Fix e2fsck to set the file type of the '..' entry when connecting
4863 a directory to lost+found. (Addresses Lustre Bug: #11645)
4865 Enhance e2fsck to recover directories whose modes field were corrupted
4866 to look like special files. This is probably only useful in
4867 artificial test cases, but it will be useful if we ever do the "inodes
4868 in directory" idea for ext4.
4870 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
4873 Fix resize2fs parsing of size parameter (in sector units). This was
4874 actually a bug in libe2p's parse_num_blocks() function. When handling
4875 the 's' suffix, it was ignoring the blocksize information passed in
4876 from the caller and always interpreting the number in terms of a 1k
4877 blocksize. (Addresses Debian Bug: #408298)
4879 There was a floating point precision error which could cause e2fsck to
4880 loop forever on really big filesystems with a large inode count.
4881 (Addresses Debian Bug: #411838)
4883 Fix memory leak in ext2fs_write_new_inode()
4885 Add support for using a scratch files directory to reduce e2fsck's
4886 memory utilization on really big filesystems. This uses the TDB
4887 library. See the [scratch_files] section of the e2fsck.conf man page
4890 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
4891 platform (Addresses Debian Bug: #397044)
4893 Add explanatory message to badblocks that -n and -w are mutually exclusive
4894 (Addresses Debian Bug: #371869)
4896 Allow debugfs and dumpe2fs to support fs features under development.
4898 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
4899 ext2fs_open() , which allows application to open filesystems with features
4900 which are currently only partially supported by e2fsprogs.
4902 Allow unix_io to support offsets greater than 2G (Addresses
4903 SourceForge Bug: #1547922)
4905 Fixed overflow and signed/unsigned problems caused by the number of
4906 blocks or inodes exceeding 2**31 or being close to 2**32-1.
4908 Add support for unsigned directory hash calculations with hints in the
4909 superblock to fix cross-architectural portability for htree
4910 directories with filenames where the high 8th bit is set. (Addresses
4913 Fix resize2fs so that it gives user-intelligible error messages if the
4914 filesystem or the kernel does not support on-line resizing.
4915 (Addresses Debian Bug: #380548)
4917 Require mke2fs -F -F for really dangerous operations, since -F is
4918 needed for less dangerous operations such as creating filesystems
4919 images in regular files, or creating filesystems on whole block
4920 devices. These relatively innocuous usages should NOT be confused
4921 with running mke2fs on an apparently-mounted or in-use filesystem.
4923 Allow the default inode size to be specified into the mke2fs.conf
4926 Make the smallest default journal size is big enough so that on-line
4927 resizing should always work.
4929 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
4932 Fix debugfs coredump when lsdel is run without an open filesystem
4933 (Addresses Debian Bug: #378335)
4935 Fix debugfs display bug us that bytes that have the high bit set are
4936 displayed as "ec" instead of "ffffffec".
4938 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
4940 Device mapper scanning wasn't working in the blkid library because the
4941 pathnames had an extra "/dev" when they were being probed.
4943 Add GFS/GFS2 support to the blkid library.
4945 Fix blkid support of empty FAT filesystem labels.
4947 Avoid recursing forever (or for a long time) when the blkid library
4948 searches for a device and there are symlinks to directories in /dev.
4950 Avoid unaligned halfword access in blkid when accessing FAT
4951 superblocks, as this will cause Sparc/Solaris systems to throw a

4955 the static link libraries for e2fsck.static if devmapper is enabled.

4958 Improve the (non-installed, for experts only) findsuper program by
4959 printing the uuid and label from the superblocks, as well as the
4960 starting and ending offsets of the filesystem given the information in
4961 the superblock. Omit by default printing superblocks that are likely
4962 found in located in an ext3 journal unless an explicit -j option is
4965 Updated Spanish, French and Dutch translations and added Catalan
4966 translation. (Addresses Debian bug: #411562)
4968 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
4969 determining a partition's size, since binary searching to determine
4970 the device doesn't work on FreeBSD.
4972 Documentation about UUID's is available in enough places, and it's
4973 awkward to deal with debian-legal's insanities. So I'm caving in the
4974 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
4975 don't have do the dfsg tarball. Also remove the rule that only tried
4976 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
4977 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
4979 Fix the info-dir line so that the menu name does not contain a .info
4980 prefix. First of all, it's ugly, secondly, it causes the install-info
4981 command to fail to remove the com_err info file from the
4982 /usr/share/info/dir file when the comerr-dev package is removed and
4983 purged. (Addresses Debian Bug: #401711)
4985 Fixed spelling mistakes, typos, and otherwise clarified man pages.

4996 E2fsck now supports the %It expansion when printing a problem report.
4997 It will print the type of the inode in the problem context.
4999 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
5000 (Addresses Sourceforge Bug: #1565561)
5002 Remove unused variables and other lint/gcc -Wall cleanups
5004 Add check to ext2fs_get_device_size() so it will return EFBIG for for
5005 filesystems contained in regular files where the filesystem image size
5006 is returned by stat64().
5008 Set local environment variables to C so mk_cmds and compile_et always
5009 work. (Addresses SourceForge Bug: #1532177)
5011 Added the 64-bit byte swapping function ext2fs_swab64().
5013 Added two new helper functions to prevent 2**31/2**32-1 overflow
5014 problems: ext2fs_div_ceil() and e2p_percent().
5016 Create new ext2fs library inline functions ext2fs_group_first_block()
5017 and ext2fs_group_last_block() in order to calculate the starting and
5018 ending blocks in a block group.
5020 Create the generated files read-only to remind developers not to edit them.
5022 Add support for autoconf 2.60 (with backwards compatibility for older
5023 versions of autoconf).
5025 Added an "make rpm" target to top-level Makefile
5027 Added various FreeBSD portability fixes.
5029 Exclude mercurial files from the RPM build tree to speed up copy/build.
5031 Use root_sysconfdir to define the locations of mke2fs.conf and
5032 e2fsck.conf instead of using a hard-coded /etc pathname.
5034 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
5036 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
5038 If diff -u is supported, use it to report test failures.
5040 Updates/improvements to RPM spec file
5042 Add on-disk format definitions for the following new features:
5043 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
5044 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
5045 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
5047 Add a new make target "checked-failed" in the tests directory which
5048 reruns any failed tests
5050 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
5052 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
5053 pointer dereferences, memory leaks, etc. None were security-critical
5056 Fix up usage and decrement error messages in the test_icount program
5058 Add debugging code to the com_err library; if the environment variable
5059 COMERR_DEBUG is set to 1, print out debugging messages as error tables
5060 are added and removed from the com_err library. If the
5061 COMERR_DEBUG_FILE environment variable is set (and the process is not
5062 setuid) the debugging messages may be redirected to a file.
5064 Change all of the e2fsprogs programs to use the newer add_error_table()
5065 and remove_error_table() interfaces instead of the much older
5066 initialize_*_error_table() function.
5068 Add TDB support into the ext2fs library. This allows us to have a
5069 guaranteed library we can count on always being present so we can
5070 store data in an on-disk database.
5072 Add support for using TDB to store the icount data, so we don't run out
5073 of memory when checking really large filesystems.
5075 Change the regression test suite so that it skips empty test directories.
5077 Define the l_i_iversion field in ext2_inode. The l_i_version field is
5078 now defined from the old l_i_reserved1 field in the ext2 inode. This
5079 field will be used to store high 32 bits of the 64-bit inode version
5082 Add Makefile production rule for e2fsprogs.spec in case it gets
5085 Add new function profile_get_uint() to allow for a clean way to fetch
5086 unsigned integers from the context.
5088 Add test to make sure the ext2 superblock structure is 1024 bytes.
5090 Fix typo in name of f_dup4 regression test
5092 Add new function blkid_gc_cache() which performs a garbage collection
5093 pass on the /etc/blkid.tab file.
5095 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
5096 general, only e2fsck (after the filesystem is clean), tune2fs, and
5097 resize2fs should change the backup superblocks by default. Most
5098 callers of ext2fs_open() should not be touching any superblock fields
5099 which require the backups to be touched.
5101 Add new function to libext2fs, ext2fs_default_journal_size(), which
5102 returns the default journal size.
5105 E2fsprogs 1.39 (May 29, 2006)
5106 =============================
5108 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
5109 between 2**31 and 2**32 blocks.
5111 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
5112 configure the filesystem features, blocksize, and inode_ratio for
5113 different filesystem types.
5115 Mke2fs will now create filesystems hash trees and on-line resizing
5116 enabled by default, based on the new /etc/mke2fs.conf file.
5118 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
5119 filesystem device node in exclusive mode to prevent accidents by
5120 system administrators. In the case of resize2fs and mke2fs, it will
5121 only use exclusive mode if the filesystem is not mounted.
5123 Fixed a bug in mke2fs which caused it to to fail when creating the
5124 resize inode for large filesystems. (Addresses Debian Bug #346580)
5126 When allocating space for the RAID filesystems with the stride
5127 parameter, mke2fs will now place each portion of the group's inode
5128 table right up after the superblock (if present) in order to minimize
5129 fragmentation of the free space.
5131 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
5132 efficiently by writing the inode and block bitmaps in one pass, thus
5133 reducing the number of disk seeks required.
5135 Add support for on-line resizing to resize2fs.
5137 Fix blkid library so that logic to determine whether or not a device's
5138 cached information in /etc/blkid.tab needs to be verified or not
5139 doesn't get confused by a system clock which is insane (for example,
5140 if the battery is dead on a Macintosh running PPC Linux. (Addresses
5141 Red Hat Bug: #182188)
5143 The blkid library will now store the UUID of the external journal used
5144 by ext3 filesystems, so that in the future, the userspace mount binary
5145 can use this to find the location of the external journal and pass
5146 this information to the kernel.
5148 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
5149 control how various options should be handled. See the e2fsck.conf
5150 man page for more details. (Addresses Debian Bug: #150295)
5152 E2fsck now prints an explanatory message when delaying a filesystem
5153 check when the system is running on battery. (Addresses Debian Bug:
5156 E2fsck will detect if the superblock's last mount field or last write
5157 field is in the future, and offer to fix if so. (Addresses Debian Bug
5158 #327580) These problems will be fixed automatically in preen mode
5159 since Debian's boot sequence bogusly doesn't set the time correctly
5160 until potentially very late in the bootup process, and this can cause
5161 false positives which will cause users' systems to fail to boot.
5162 (Addresses Debian Bugs #343662 and #343645)
5164 E2fsck now checks to see if the superblock hint for the location of
5165 the external journal is incorrect, and if so, offer to update it.
5166 (Addresses Debian Bug: #355644)
5168 Fix e2fsck from segfaulting on disconnected inodes that contain one or
5169 more extended attributes. (Addresses Debian Bug: #316736, #318463)
5171 E2fsck will stop and print a warning if the user tries running a
5172 read/write badblocks test on a read-only mounted root filesystem.
5174 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
5175 C. Thompson for pointing these out; they were originally found using
5178 When resizing a file containing a filesystem, resize2fs will expand or
5179 truncate a file as necessary. (Addresses Debian Bug: #271607)
5181 Resize2fs will now automatically determine the RAID stride parameter that
5182 had been used to create the filesystem, and use that for newly created
5183 block groups. The RAID stride parameter may also be manually specified
5184 on the command line using the new -S option to resize2fs.
5186 Fix mke2fs so that it correctly creates external journals on
5187 big-endian machines (such as a S/390).
5189 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
5190 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
5191 Chambraud for pointing this out.)
5193 Dumpe2fs will now print the size of the journal (if present).
5195 Fix debugfs's set_inode_field command so it can properly set the frag,
5196 fsize, uid_high, gid_high, and author fields in the inode instead of
5197 silently failing, and so that setting the i_size actually sets i_size
5200 Add a new debugfs command, set_current_time, which sets fs->now so
5201 that regression test suites can repeatedly modify the filesystem's
5204 Fix a bug in debugfs's icheck which would incorrectly report the owner
5205 of an extended attribute block.
5207 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
5208 print a usage message when an illegal option character is given.
5210 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
5211 so it won't core dump. (Addresses SourceForge bug #1424311)
5213 Fix mklost+found so that it creates a full-sized directory on
5214 filesystems with larger block sizes.
5216 Fix a file descriptor leak in blkid library.
5218 Fix a display bug in "badblocks -sv" so that the done message properly
5219 clears the block number at the end of the test. (Addresses Debian Bug
5222 Allow fractional percentages to the -m option in mke2fs and tune2fs
5223 (Addresses Debian Bug: #80205)
5225 Use fstat/fstat64 in getsize.c if the the target is a regular file,
5226 instead of attempting to do a binary search. Fix some fd leaks in
5229 Add support for device mapper library to the blkid library to ensure
5230 that the "best" (i.e., leaf) device is probed by the blkid library.
5232 Fix the blkid library so that it notices when an ext2 filesystem is
5235 Improve the blkid's library VFAT/FAT detection; it now understands
5236 labels stored in the root directory, and is more paranoid about
5237 checking the FAT superblock values.
5239 Fixed a fd leak in the uuid library which was causing problems for the
5240 LVM tools. (Addresses Debian Bug: #345832)
5242 Add support for the reiser4 and software suspend partitions to the
5243 blkid library. Also add support for extract the label from iso9660
5246 Fix a compile_et bug which miscount the number of error messages if
5247 continuations are used in the .et file.
5249 Add extra sanity checks to protect users from unusual circumstances
5250 where /etc/mtab may not be sane, by checking to see if the device is
5251 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
5254 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
5255 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
5257 Fix use-after-free bug in e2fsck when finishing up the use of the
5258 e2fsck context structure.

5278 Bugs: #360661, #360317)
5280 Fixed the Makefile so that they work correctly on newer versions of
5281 GNU make (i.e., 3.81).
5283 Add valgrind support to the regression test suites, and eliminate
5284 false positives from valgrind.
5286 Add a regression test suite for the blkid library.
5288 Fix a fencepost error in resize2fs caught by valgrind.
5290 Fix compiler warnings about missing memcpy prototypes.
5292 We no longer have the sparc assembly code in the header file any more,
5293 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
5294 break compiles on the sparc architectures when using gcc.
5296 In the libext2fs library, add the new field fs->now which if non-zero
5297 is used instead of the system time when setting various filesystem
5298 fields (last modified time, last write time, etc.)
5300 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
5301 ext2fs.h which is needed since the inline functions use memcpy().
5302 (Addresses Sourceforge Bug #1251062)
5304 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
5305 the build system when building files in the util directory which are
5306 needed during the build process. This avoids potential problems when
5307 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
5308 are not recognized as valid by the host compiler. (Addresses
5309 Sourceforge Bug #1261547)
5311 Clean up the blkid library by making the superblock and generic i/o
5312 functions to be more generic. Clean up interface to the probe
5313 function, and fix memory leak. Finally, remove an unneeded reference
5314 to probe.h in the lib/blkid/resolve.c
5316 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
5317 of invalid block #'s.
5319 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
5320 indicate that the the function read/writes the memory location.
5322 Fix various gcc -Wall complaints.
5324 Add a dependency to make sure that the subdirectories are created
5325 before creating all of the object files, in order to address parallel
5326 build problem in the library Makefiles. (Addresses Sourceforge Bug:
5329 Add $(LDFLAGS) to the command line argument when generating an ELF or
5330 Solaris shared library, to allow cross-compile and other builds that
5331 might need to specify -L paths to needed libraries. (Addresses
5332 Sourceforge Bug #1261549)
5334 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
5335 intended for testing purposes. It allows an ext2/ext3 developer to
5336 create very large filesystems using sparse files where most of the
5337 block groups are not initialized and so do not require much disk
5338 space. Eventually it could be used as a way of speeding up mke2fs and
5339 e2fsck for large filesystem, but that would be best done by adding an
5340 RO_COMPAT extension to the filesystem to allow the inode table to be
5341 lazily initialized on a per-block basis, instead of being entirely
5342 initialized or entirely unused on a per-blockgroup basis.
5344 Fix backwards compatibility so e2fsprogs will better compile on Linux
5347 Make test scripts more robust against locale-related environment variables
5349 Fix type warning problem with sizeof() in ext2fs_open2().
5351 Fix type warning problem with time_t in debugfs.
5354 E2fsprogs 1.38 (June 30, 2005)
5355 ==============================
5357 Fix blkid's test programs (built with "make check") compile correctly
5358 even without "configure --enable-blkid-debug".
5360 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
5361 type aliasing rules on newer gcc compilers. (Addresses Red Hat
5364 Fix com_err library to make it more compatible with recent changes
5365 made to the com_err library in MIT Kerberos V5 version 1.4.
5366 (Addresses Sourceforge Bug #1150146)
5368 General cleanup of messages printed by e2fsprogs programs for grammar,
5369 consistency, and to make life easier for translators. Fixed a few
5370 strings containing English that had not been marked as needing
5371 translations. Removed strings that do not need to be translated, to
5372 make life easier for translators.
5374 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
5375 test to see if a device appears to be in use instead of just relying
5376 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
5378 Fix portability problem in the filefrag program affecting platforms
5379 where the size of an integer is smaller than the size of a long.
5380 (Addresses Debian Bug #309655)
5382 Mke2fs will now use a larger journal by default for filesystems
5383 greater than 4GB. (128 MB instead of 32MB).
5385 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
5386 unless forced. This is to avoid signed vs. unsigned kernel bugs in
5387 block numbers that still need to be fixed.
5389 The blkid program has a new option which will more efficiently search
5390 for device when it is known (or expected) that only one matching
5391 device will be found in the system, such as when doing a lookup by
5394 Debian's e2fsprogs-specific initrd fragment will avoid including
5395 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
5396 and LD_LIBRARY_PATH, and filtering out libraries found in
5397 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
5399 Fixed a potential portability issue in the blkid programs for
5400 architectures where the char type is unsigned. (Addresses Sourceforge
5403 Fix a bug in filefrag so that it doesn't falsely count an extra
5404 discontinuity when the first block found is an indirect block.
5405 (Addresses Debian Bug #307607).
5407 Fix blkid's recognition of cramfs filesystems, and enhance it to be
5408 able to handle cramfs labels.
5410 Fix debugfs's stat command to not core dump when a filesystem is not
5413 Fix e2fsck's handling of error conditions caused by the resize inode
5414 claiming blocks that are also used by other inodes, a filesystem
5415 corruption which was commonly caused by a bug in Fedora Core 3's
5418 Fixed bug in filefrag which caused it to fail on non-ext2/3
5419 filesystems. (Addresses Debian Bug: #303509)
5421 If the superblock last mount time indicates that the system clock may
5422 not be accurate, then e2fsck will omit checking inodes' deletion time
5423 field for indications of a potential corrupted orphaned inode list.
5424 (Previously e2fsck only omitted these LOW_DTIME checks when the
5425 superblock's last write time looked insane.)
5427 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
5428 (Addresses Debian bug #302200)
5430 Make the blkid library more paranoid about being run from setgid
5431 programs, and to use __secure_getenv() from libc if it is available.
5433 Fixed spelling mistakes, typos, and otherwise clarified man pages.
5434 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
5435 and Sourceforge Bug: #1189803)
5437 Updated and fixed translations.
5439 Fixed various Debian packaging issues --- see debian/changelog for
5445 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
5446 changed to take an unsigned int for the bit number. Negative bit
5447 numbers were never allowed (and didn't make any sense), so this should
5448 be a safe change. This is needed to allow safe use of block numbers
5449 greater than or equal to 2**31.
5451 The compile_et program will avoid recreating generated foo_err.c and
5452 foo_err.h files if no changes are necessary. The compile_et program
5453 will also atomically replace these files to avoid a potential parallel
5454 build race problem on SMP systems. (Addresses Sourceforge Bug:
5457 Added a new function to the blkid library, blkid_probe_all_new(),
5458 which only probes newly added disk devices, and change
5459 blkid_find_dev_with_tag() to use this function so that when a
5460 requested tag is not found, devices that were previously not checked
5461 are searched before searching all devices in the system.
5463 Added new functions to the blkid library, blkid_dev_set_search() and
5464 blkid_dev_has_tag().
5466 E2fsck's problem strings can now use @m and @n as abbreviations for
5467 "multiply-claimed" and "invalid", respectively.
5469 The e2fsprog.pot file now has an explanation of how the @-expansion
5470 and %-expansion works, and strings in e2fsck/problem.c which contain @
5471 characters now have comments in e2fsprogs.pot with the @-expansion to
5472 make life easier for translators.
5474 Fixed missing return values in the ext2fs library which could cause it
5475 to return random garbage in certain error conditions.
5477 Allow the current time to be overridden via the E2FSCK_TIME environment
5478 variable for use in regression tests.
5480 The test script driver program now exits with a non-zero status if
5481 there any of its test that it ran failed.
5483 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
5486 Fixed "make check" so that it compiles correctly even when e2fsprogs'
5487 header files have not be installed in the system include directories.
5488 (Addresses Sourceforge Bug: #1180572)
5490 Fixed gcc -Wall nits.
5493 E2fsprogs 1.37 (March 21, 2005)
5494 ===============================
5496 Add support for checking the validity of Extended Attributes stored in
5499 Add support for dumping the contents of large inodes to debugfs,
5500 including the extended attributes stored in inodes.
5502 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
5503 when we create a new inode we make sure that the extra information in
5504 the inode (any extra fields in a large inode and any ea-in-inode
5505 information) is initialized correctly. This can take place when
5506 mke2fs creates the root and lost+found directory, when e2fsck creates
5507 a new root inode or a new lost+found directory, and when the user uses
5508 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
5509 create inode could inherit garbage (or old EA information) from a
5510 previously deleted inode.
5512 Fixed a bug in e2fsck so it would notice if a file with an extended
5513 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
5516 Added support to filefrag to detect files which are using the new
5517 experimental file extents format, and use the non-ext2 algorithm in
5518 that case. Fixed a bug to avoid reporting a false discontinuity if
5519 there is one or more unallocated blocks at the beginning of a file.
5521 Duplicated a check for noticing whether or not the number of blocks
5522 (given a certain blocksize) is greater than 2**32 when the
5523 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
5524 allows mke2fs to automatically use a larger blocksize when creating a
5525 filesystem on a very large device when run on systems that do not
5526 support BLKGETSIZE64.
5528 Fix the I18N build which was broken in e2fsprogs 1.36 because the
5529 build system had been switched to treat the .gmo files as shipped
5530 files (for backwards compatibility with systems that have older GNU
5531 I18N tools installed), but the gen_tarball.in script was still
5532 removing the .gmo files from the official source distribution.
5534 Fixed various Debian packaging issues --- see debian/changelog for
5535 details. (Addresses Debian Bugs ##296769, #299341)
5540 Added new functions to the e2p library which convert between a string
5541 and os_type: e2p_os2string() and e2p_string2os(), and used them to
5542 make the generated binaries more compact.
5544 Fixed a compile-time error on Darwin systems.
5546 Cleaned up the lib/ext2fs Makefile slightly.
5549 E2fsprogs 1.36 (February 4, 2005)
5550 =================================
5552 All of the patches that were applied to Fedora Core 3's
5553 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
5554 lot of bug fixes first. Users of Fedora Core 3 are strongly
5555 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
5557 Add support for filesystem with the online resizing via resize inode
5558 feature. Fixed numerous bugs from the Fedora patches. The Fedora
5559 patches also didn't bother to do any consistency checking on the
5560 resize inode, or add any tests to the regression test suite. The "-R
5561 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
5562 being listed in mke2fs's usage message. All of these shortcomings
5563 have been corrected.
5565 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
5566 program. In order to do this, the user must run the commands:
5568 debugfs -w /dev/hdXXX -R "features ^resize_inode"
5569 e2fsck -f /dev/hdXXX
5571 Optionally, the ext2prepare command can be used to re-enable online
5572 resizing after the filesystem has been fixed.
5574 The fsck program will now accept an optional filedescriptor argument
5575 to the -C option. (The Fedora version of this patch would sometimes
5576 cause fsck to ignore a parameter on fsck's command line in some rare
5579 Make sure e2fsprogs doesn't write garbage into the reserved portion of
5582 Make sure resize2fs releases the blocks belonging to the old inode
5583 table blocks when moving the inode table. (Addresses Debian Bug:
5586 Skip the r_resize_inode test if resize2fs is not compiled (due to
5587 configure --disable-resizer)
5589 E2fsck now checks the summary filesystem accounting information, and
5590 if any of the information is obviously wrong, it will force a full
5591 filesystem check. (Addresses Debian Bug #291571)
5593 Fix e2fsck to not complain when the resize_inode feature is enabled,
5594 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
5597 Fix e2fsck to note delete symlinks that contain an extended attribute
5598 after the ext_attr feature flag has been cleared. (Addresses Red Hat
5601 Add new utility program, copy_sparse.c, which is very useful
5602 for dealing with large sparse files (such as e2image files).
5604 Add support for jnl_blocks[] for debugfs's set_super_value.
5606 Fix filefrag so that it works correctly with sparse files.
5608 Filefrag -v will print first and last blocks.
5610 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
5613 Add mke2fs support so that it can support filesystems larger than 4TB
5614 automatically, by retrying with a 4k blocksize if the device size is
5615 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
5618 Change blkid to test for NTFS first because Windows sometimes doesn't
5619 clear enough of the partition to confuse the probing routines into
5620 thinking the old filesystem type is still valid. (Addresses Debian
5623 Add support for swap partition label and uuid's in the blkid library.
5625 Add support to the blkid library to recognize Oracle ASM volumes.
5627 Make blkid -t display all devices that match the specified criteria,
5628 not just the first one, and work more consistently when the blkid
5629 cache file is not available or set to /dev/null. (Addresses Debian
5630 Bug #290530 and #292425)
5632 Badblocks will now correctly display block numbers greater than
5633 999,999,999 in its progress display.
5635 The tune2fs program will not allow the user from setting a ridiculous
5636 number of reserved blocks which would cause e2fsck to assume the
5637 superblock was corrupt. E2fsck's standards for what is a ridiculous
5638 number of reserved block has also been relaxed to 50% of the blocks in
5641 The blkid library will return vfat in preference to msdos, and ext3 in
5642 preference to ext2 (if the journalling flag is set) so that mount will
5643 do the right thing. (Addresses Debian bug #287455)
5645 Mke2fs will now use the -E option for extended options; the old -R
5646 (raid options) option is still accepted for backwards compatibility.
5647 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
5649 Mke2fs will now accept a size in megabytes, gigabytes, and other units
5650 (via "32m" or "4g" on the command line) if the user finds this more
5651 convenient than specifying a block count.
5653 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
5654 cache coherency problem.
5656 Debugfs now supports a new command, set_inode_field, which allows a
5657 user to manually set a specific inode field more conveniently, as well
5658 as set entries in the indirect block map.
5660 Debugfs's set_super_value command has been enhanced so that the user
5661 can set most superblock fields, including the date/time fields and
5662 some of the more newly added superblock fields.
5664 E2fsprogs programs now accept an offset to be passed to the file
5665 specifiers, via the syntax: "/tmp/test.img?offset=1024".
5667 E2fsprogs programs will now accept blocksizes up to 65536; kernel
5668 support on the x86 doesn't exist for now, but it can be useful on
5669 other architectures with page sizes greater than 4k. There are 2.6
5670 kernel patches out there which enable this, but they are of this
5671 writing still experimental.
5673 The e2image command now takes the -s option which will scramble
5674 directory entries for raw image files.
5676 Fix a file descriptor leak in the filefrag program.
5678 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
5681 Fix bug in debugfs where kill_file would lead to errors when deleting
5682 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
5684 Fix bug in the blkid library when detecting the ocfs1 filesystem
5686 Remove obsolete EVMS 1.x and a.out DLL support.
5688 E2fsck will attempt to recover from a journal containing illegal blocks.
5690 Fixed two potential ordering constraint problems in e2fsck which might
5691 cause the filesystem to be corrupted if e2fsck is interrupted during a
5692 (extremely narrow) race window. Thanks to Junfeng Yang from the
5693 Stanford Metacompilation group for pointing this out.
5695 Fixed bug in e2fsck where it would not accurately detect whether or
5696 not the system is running on adaptor if the ACPI device representing
5697 the AC adapter didn't correspond to the what was used on IBM
5700 Change e2fsck to accept directories greater than 32MB.
5702 Fix e2fsck so that a checkinterval of zero disables a time-based check
5705 Debugfs will check the DEBUGFS_PAGER environment variable in preference
5706 to the PAGER environment variable. (Addresses Debian Bug #239547)
5708 Tune2fs will not mark rewrite the superblock if the feature bitmasks
5711 The debugfs program will set the filetype information when creating a
5714 Add debugfs -d option to use a separate source of data blocks when
5715 reading from an e2image file.
5717 Add e2image -I option which allows the e2image metadata to be
5718 installed into a filesystem.
5720 Fixed bug in the badblocks program which caused "done" to always
5721 appear in English even when a translation was available. (Addresses
5724 The blkid program has a new option -o which controls the output format
5725 of the blkid program; this is makes blkid more convenient to use in
5728 Fix a minor bug in uuid library, which was not using the full 14 bits
5729 of clock sequence when generating UUID's.
5731 Fix a Y8.8888K problem in the uuid library.
5733 Logsave now creates a new session id for itself to avoid getting
5734 killed by init when transitioning between init levels.
5736 Change the licensing of the UUID library to be the 3-clause BSD-style
5737 license; this allows Apple to use the uuid library in Darwin.
5739 Add ocfs and ocfs2 probe support into the blkid library.
5741 Fix a memory and file descriptor leak in the blkid library.
5743 The blkid library will revalidate the device if the system time is
5744 earlier than last verification time of the device, since that
5745 indicates that the system time is probably not trustworthy.
5747 The blkid library will override the default location of the blkid.tab
5748 file by the BLKID_FILE environment variable, if it is available.
5750 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
5752 Add various portability fixes for lame new versions of glibc, Darwin
5753 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
5754 Bugs #239934, #264630, #269044, #255589, #289133)
5756 Add support for Windows 9x/NT under Cygwin.
5758 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
5759 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
5761 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
5763 Update the rpm spec files so that it works better with Fedora core 2
5766 Fixed various Debian packaging issues (see debian/changelog). In
5767 particular, fixed the Debian initrd scripts. (#241183, #248050,
5774 Fixed various gcc -Wall warnings.
5776 The uuid library now has new functions uuid_unparse_upper() and
5777 uuid_unparse_lower() which forces the case of the hex digits to be
5778 upper case, or lower case.
5780 The build process has been sped up by enhancing the subst program
5781 to update the modtime on the generated files even when the generated
5782 file hasn't changed.
5784 The uuid library now uses C99 stdint.h types instead of custom types.
5786 Updated config.guess and config.sub with newer versions from the FSF.
5788 Removed out of date .cvsignore files from the source distribution.
5790 The ext2fs_unlink() function will return an error if both the name and
5791 inode number are unspecified, to avoid doing something surprising
5792 (such as unconditionally deleting the first directory entry).
5793 Directory entries are now deleted by coalescing them with the previous
5794 directory entry if possible, to avoid directory fragmentation. This
5795 is not an issue with the e2fsprogs suite, but may be a problem for
5796 some of the users of libext2fs, such as e2tools.
5798 Add support for version numbers of the form "1.36-rc1".
5800 Fix build of mke2fs.static.
5802 Add basic ext2fs library support for large (EA in inode) inodes.
5804 The test_io mechanism can now abort after n reads or writes to a
5805 particular block. The block is specified by TEST_IO_BLOCK environment
5806 variable, and the read/write count by the TEST_IO_READ_ABORT and
5807 TEST_IO_WRITE_ABORT environment variables. The block data is now only
5808 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
5810 UUID_DEFINE() in the uuid library now creates a static variable, with
5811 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
5812 be used in header files.
5814 Add support for the install-strip and install-shlibs-strip targets, as
5815 suggested by the GNU coding guidelines. "make install" no longer
5816 strips the binaries which are installed.
5818 Remove support for the --enable-old-bitops configure option which was
5819 only for very old sparc systems.
5821 Remove support for --enable-clear-htree; this was only needed during
5822 the early development of the htree patch.
5824 Use Linux-kernel-style makefile output so it is easier to see compiler
5827 Update gettext files to version 0.14.1.
5829 Update to use autoconf 2.5x.
5831 Improved support for compiling e2fsprogs under dietlibc.
5833 Make e2fsprogs portable to Solaris and FreeBSD systems.
5835 Add blkid_verify(), blkid_get_library_version(), and
5836 blkid_parse_version_string() functions to the blkid library.
5838 Add pkg-config files for e2fsprogs's libraries.
5840 Fix "make uninstall" to so that it removes everything that is installed.
5842 Add a configure --enable-maintainer-mode option which enables the
5843 makefile rules to rebuild the configure script from configure.in, and
5844 to rebuild the .gmo files in po directory.
5846 Drop the sparc assembly bitwise operations; it's less efficient
5847 than the GCC 3.4 compile code and triggers compiler warnings on
5848 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
5849 (Addresses Debian Bug #232326)
5852 E2fsprogs 1.35 (February 28, 2004)
5853 ==================================
5855 E2fsck has a new -k option, which in conjunction with the -c options,
5856 preserves the existing badblocks list.
5858 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
5860 E2fsprogs will now deal correctly with symlinks that contain
5861 extended attribute information, which can be created using SE Linux.
5862 (Addresses Debian Bug #232328)
5864 Remove a double longjmp into an invalid stack frame bug in e2fsck.
5865 (This was during an abort sequence, which normally worked on Linux and
5866 caused a core dump on other operating systems.)
5868 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5869 (the NLS library will replace "" with the .po header information).
5871 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
5872 dump due to a division by zero error. (Addresses Debian bug #207082)
5874 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
5875 when reconnecting a directory requires creating a lost+found
5876 directory. (Addresses Debian bug #219640).
5878 Fixed a bug where e2fsck would bomb out if a journal needed to be
5879 replayed when using an alternate superblock.
5881 E2fsck will give an extra grace period before actually forcing a check
5882 if the laptop is running on battery. The next time fsck runs while
5883 the system is on the AC mains, or after the grace period is exceeded,
5884 the filesystem will be checked. (Addresses Debian bug #205177)
5886 E2fsck will inform the user when there are 5 or fewer mounts before a
5887 filesystem check will be forced. (Addresses Debian bug #157194)
5889 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
5890 We now correctly handle the case where there is an overlap between a
5891 block group descriptor or a superblock and a bad block indirect block.
5892 In the case where the indirect block is corrupted, we now suggest
5895 Fix byte swap bugs in e2fsck that caused the journal backup location
5896 in the superblock and symlinks created by SE Linux to be cleared
5897 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
5899 E2fsck -c now replaces the current list of bad blocks with the ones
5902 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
5903 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
5905 Fix a potential bug in e2fsck which could cause it to core dump when
5906 trying to print the location of the backup superblock.
5908 Protect against a potential core dump in e2fsck when printing a
5909 message about backup superblocks.
5911 Add support for backing up the journal inode location in the
5912 superblock. E2fsck will automatically save the journal information in
5913 the superblock if it is not there already, and will use it if the
5914 journal inode appears to be corrupted. ext2fs_add_journal_inode()
5915 will also save the backup information, so that new filesystems created
5916 by mke2fs and filesystems that have journals added via tune2fs will
5917 also have journal location written to the superblock as well.
5918 Debugfs's logdump command has been enhanced so that it can use the
5919 journal information in the superblock.
5921 E2fsck will now update all superblocks when moving the journal inode.
5923 Shrink the size of the e2fsck executable by moving some initialized
5924 variables to the BSS segment.
5926 E2fsck will avoid printing the ^A and ^B characters which bracket the
5927 progress bar when stdout and stdin are a tty device instead of a pipe
5928 to another program. (Addresses Debian bug #204137)
5930 Debugfs's mkdir command will automatically expand the directory if
5931 necessary. (Addresses Debian Bug: #217892)
5933 Fixed a bug in debugfs so that copying a file from /dev/null uses the
5934 correct mode bits. (Addresses Debian Bug: #217456)
5936 If the environment variables DEBUFS_PAGER and PAGER are not set,
5937 debugfs now searches for the appropriate pager to use, beginning with
5938 /usr/bin/pager, and then falling back to 'more' and 'less'.
5939 (Addresses Debian bug #221977)
5941 Debugfs will now support 2.6 device numbers where the major or minor
5942 number may be larger than 255. (Addresses Sourceforge bug #865289)
5944 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
5946 Chattr now stops processing options when it sees '--'. (Addresses
5949 Fix regression tests so they work correctly when e2fsprogs is compiled
5950 with configure --disable-htree.
5952 Fix bug in uuid library when there is no network card and the library
5953 is generating a time-based uuid. The random MAC address was not
5954 correctly generated to be a multicast address.
5956 Add compile_et extensions from Heimdall that were missed the first time
5959 Fix bug in badblocks when using O_DIRECT; we need to make sure that
5960 we're reading from an offset which is page aligned. For read-only and
5961 read-write tests, we try to recover after an error so that we can
5962 continue reading on page-aligned boundaries. (Addresses Debian Bug
5965 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
5968 Updated and clarified various man pages. (Addresses Debian Bug
5969 #206845, #222606, #214920, #232406)
5971 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
5973 Fixed various Debian packaging issues (see debian/changelog).
5978 Fixed a build problem so that e2fsprogs would compile with the
5979 --enable-profile option to configure selected. (Addresses Sourceforge
5982 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
5983 Bugzilla Bug #112448)
5985 Centralize code which calculates the location of the superblock
5986 and block group descriptors so that it is in a single library routine.
5988 Added two new functions, ext2fs_file_open2() and
5989 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
5991 Fix compile_et to output the correct prototype for
5992 initialize_xxx_err_table_r() in the header file. (Addresses Debian
5995 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
5997 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
5998 present. This is for when we try stuffing an int into void * pointer.
6000 Fix type-punning which can cause gcc 3.x to miscompile code by getting
6001 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
6002 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
6003 **'. The EVMS code uses an ugly union approach since we don't want to
6004 modify the EVMS interfaces.
6006 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
6007 aid build process on systems can use invoke GNU make as "gmake".
6009 Added regression testing for mke2fs.
6011 Fixed gcc -Wall nitpicks.
6013 Fixed various compiler warnings.
6015 Add portability fixes for FreeBSD and for using fsctl under Darwin to
6016 support ext2 ioctl's.
6019 E2fsprogs 1.34 (July 25, 2003)
6020 ===============================
6022 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
6023 a tight loop while waiting for a child fsck to exit in some cases.
6024 This burns CPU times which slows down the low-level filesystem check.
6026 Added code to mke2fs to assure that the default block size for a
6027 filesystem is at least as big as the sector size of the device, if it
6030 Changed mke2fs and resize2fs to round the default size of a filesystem
6031 to be an even multiple of the VM pagesize in order to avoid a Linux
6032 kernel bug introduced when the storage of the buffer cache was moved
6033 into the page cache.
6035 Mke2fs will warn the user when creating a filesystem with journalling
6036 and a blocksize greater than 4096. (Addresses Debian bug #193773)
6038 Fixed a bug in resize2fs which caused it to fail on filesystems with a
6039 non-empty bad block list. Resize2fs now discards any blocks on the
6040 badblock list which are no longer part of the filesystem as the result
6041 of a filesystem shrink. (Note: this means that shrinking and then
6042 enlarging a filesystem is no longer a reversible operation;
6043 information about bad blocks in the part of the filesystem which is to
6044 be chopped off will be lost.)
6046 Changed resize2fs so the user can use prefixes to specify the units of
6047 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
6048 and to make the error and informational messages explicitly display
6049 the blocksize used by the filesystem, in order to avoid confusion.
6050 (Addresses Debian bug: #189814)
6052 Added a new debugfs command, dump_unused, which dumps the contents of
6053 all unused blocks to stdout. (Useful as an emergency try-to-find
6054 deleted data command.)
6056 Added a new debugfs command, imap, which prints the location of a
6057 specified inode in the inode table.
6059 Fixed a bug in the badblocks program which caused it to use one bit of
6060 randomness in its non-destructive read/write test, instead of using a
6061 full 8 bits of randomness.
6063 Added a new option (-t) to badblocks, which allows the user to control
6064 the test pattern(s) used when checking a disk.
6066 The blkid probe function now more correctly detects UDF filesystems.
6068 Fixed a bug in the blkid library which caused it to not update its
6069 cache if a filesystem changes from having a label to not having a
6072 Fixed a bug in the blkid library which could avoid an infinite loop
6073 in blkid_find_dev_with_tag() if /proc is not mounted and there the
6074 /etc/blkid.tab file has not yet been created.
6076 Fixed the badblocks program so that the destructive read/write test
6077 honors the -c option, and to use O_DIRECT when possible to avoid
6078 thrashing the system block buffer cache.
6080 Fixed various NLS issues.
6081 - Added Czech and Swedish translations
6082 - Removed testing NYC translation
6083 - Fixed NLS support for message abbreviations in e2fsck
6084 - Remove de-utf.po, since we shouldn't have two versions using different
6086 - Used ngettext() (abbreviated with the macro P_(str1, str2, n)) to
6087 simplify the statistics reporting in e2fsck.
6089 Changed configure.in so that its defaults for *BSD systems no longer
6090 build an fsck wrapper, and not to install in /usr/local by default.
6092 Fixed some minor spelling errors/typo's in e2fsck and the configure
6095 Fixed various Debian packaging issues (see debian/changelog).
6097 Updated and clarified man pages. (Addresses Debian Bug #195616)
6102 Fix gcc -Wall nitpicks.
6104 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
6105 NLS support by default. (Added partial workaround for gettext/Darwin
6106 incompatibility problems.)
6108 Added full MIT KRB5 and Himdall compatibility support to the com_err
6109 library and the compile_et program. (Addresses Debian bug #191900)
6111 Added the blkid_known_fstype() function to the blkid library, which
6112 returns true if it is passed a filesystem type which is recognized by
6113 the blkid probing functions.
6115 Improved the documentation for the blkid library.
6117 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
6118 returns the hardware sector size of a device, if it is available.
6120 Added a dependency in the blkid library's .so file to the uuid
6121 library, since the former uses the latter. (Addresses Debian bug
6124 Added --with-diet-libc and --disable-evms to the configure script.
6126 Fixed a minor memory leak in the badblocks program.
6128 Fixed a portability problem in tune2fs --- not all systems have strptime().
6130 Fixed a portability problem in debugfs with the use of getopt() more
6131 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
6134 Add support Windows support to ext2fs_get_device_size().
6136 Added (normally disabled) debugging code to the Unix I/O manager which
6137 causes it to disable all userspace caching if the NO_IO_CACHE is
6140 Changed the test I/O manager so it can always be linked into e2fsck,
6141 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
6142 configure script. The test I/O manager will only print any debugging
6143 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
6144 variables are set, which specifies which I/O operations are logged and
6145 a block number to watch, respectively. The log messages are sent to
6146 stderr by default, unless a filename is specified via the
6147 TEST_IO_LOGFILE environment variable.
6150 E2fsprogs 1.33 (April 21, 2003)
6151 ===============================
6153 Added a new utility program, logsave, which captures the output of a
6154 command in a log file, even if the containing directory hasn't been
6155 mounted yet (in which case the it saves the output in memory until it
6156 can write out the logfile). This is useful for capturing the
6157 output of fsck during the boot sequence.
6159 Fixed some portability problems that were causing problems under
6160 the Cygwin32 environment.
6162 Mke2fs now interprets a negative number to the -b option as a minimum
6165 Fixed a bug in mke2fs which was incorrectly checking the argument to
6166 the -g option if the default block size was used. (Addresses Debian
6169 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
6170 it can not find filesystem checkers for jfs, reseirfs, and xfs.
6172 E2fsck now updates the global free block and inode counters from the
6173 block group specific counters quietly. This is needed for an
6174 experimental patch which eliminates locking the entire filesystem when
6175 allocating blocks or inodes; if the filesystem is not unmounted
6176 cleanly, the global counts may not be accurate.
6178 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
6179 2.0 is not yet supported; this only pulled in the bug fixes: fixed
6180 possible hangs caused by bugs in calling waitpid, and not setting the
6181 pipe to non-blocking mode; also fixed a file descriptor leak; made
6182 sure all functions call log entry/exit functions.)
6184 Badblocks now flushes its output file as bad blocks are discovered.
6186 The uuid library is now more paranoid about assuming the correctness
6187 of the /dev/random device; it mixes in a stream of bytes from
6188 random/srandom, just in case.
6190 Update Debian files to reflect the fact that I am now the Debian
6191 maintainer of e2fsprogs. Other various Debian-specific packaging
6194 Move the source tarball generation functions from the top-level
6195 makefile to the util/gen-tarball script.
6197 Updated the Turkish .po translation file.
6199 Added Heimdal and MIT krb5 extensions to the com_err library to make
6200 it more compatible with com_err libraries from those distributions.
6202 Changed dumpe2fs to always display the superblock fields relating to
6203 the journalling and/or directory indexing feature even if those
6204 features are not enabled.
6206 Updated and clarify copyright statement vis-a-vis alpha releases of
6209 The ss library will now try to dynamically link to the readline
6210 library and use it if it is present in the system. This means that
6211 the debugfs program now has line editing and history features. The
6212 SS_READLINE_PATH environment variable is used to find a readline or
6213 readline-compatible library.
6215 E2fsck now finds most duplicate filenames (all when rebuilding all
6216 directories via the -D option) and offers to delete or rename
6217 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
6219 Fix bug in e2image. When writing out a raw image file, include data
6220 blocks from symlinks that do not store the symlink within the inode.
6222 Fix bug in resize2fs which incorrectly moved the block and inode
6223 bitmaps for sparse superblock filesystems and incorrectly marked
6224 blocks as in use. (Addresses Debian bug #174766)
6226 Added a new shared library, the blkid library, which efficiently
6227 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
6228 and UUID filesystem specifiers without needing to search all of the
6229 devices in the system. Instead, the device is looked up in a cache
6230 file, and then verified to make sure the blkid cache is correct.
6232 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
6233 the device name, using the blkid library. (Addresses Debian bugs
6236 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
6237 used for spaces in device labels.
6239 Removed 32-bit limitations for debugfs's dump command.
6241 If the user specifies a large number of inodes, Mke2fs will
6242 automatically adjust the number of blocks per group to find a valid
6243 set of filesystem parameters.
6245 Add workaround to detect broken MD devices where when some of the
6246 underlying devices are marked read-only, writes to the MD device are
6247 silently dropped. E2fsck will detect if there is an attempt to run
6248 the journal twice, and abort with an error if this is the case.
6249 (Addresses IBM Bugzilla bug #1226)
6251 E2fsck will print an error if more than one of the -p/-a, -n or -y
6252 options are specified.
6254 E2fsck will fix HTREE corruptions in preen mode, without stopping the
6255 boot process. This is needed because the 2.4 ext2 filesystem
6256 accidentally had the INDEX_FL backwards compatibility code removed.
6258 Mke2fs no longer creates filesystems with the dir_index flag set by
6259 default; the user has to specifically request it.
6261 Update and clarified various man pages. (Addresses Debian bugs
6262 #173612, #175233, #175113, and #170497, #185945, #188318)
6264 Created man page for the mk_cmds program (from the libss library).
6269 Fix various gcc -Wall nits.
6271 Fixed a lot of portability problems that caused e2fsprogs not to build
6272 successfully under Solaris and Apple/Darwin.
6274 Fixed a Makefile dependency to allow building e2fsprogs using parallel
6277 Changes to create a subset distribution which consists only of the
6278 et, ss, uuid, and blkid libraries. The configure script and top-level
6279 makefile were changed to support working with a subset distribution.
6281 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
6282 actually used, and might people who are looking for
6283 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
6285 Updated debian files to fix a number of Lintian warnings.
6287 Updated config.guess and config.sub with newer versions from the FSF.
6289 Removed unnecessary libraries from being linked into the fsck, lsattr,
6290 chattr, and blkid executables.
6292 E2fsprogs 1.32 (November 9, 2002)
6293 =================================
6295 Fixed a bug in the Unix I/O routines which caused needless writebacks
6296 of clean blocks from the unix_io cache (they were erroneously marked
6297 as being dirty, so they were getting written back to disk before
6298 getting evicted from the disk cache). This was harmless, but it
6299 significantly slowed down e2fsck.
6301 Made some other minor optimizations to the Unix I/O routines to save a
6302 small amount of CPU time.
6304 Updated internationalization files.
6307 E2fsprogs 1.31 (November 8, 2002)
6308 =================================
6310 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
6311 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
6312 handling for child process that die unexpectedly. Add a hack to force
6313 mkfs to create filesystems that won't cause problems with hardware
6314 that has 2k or 4k minimum blocksize requirements. Read from child
6315 processes in non-blocking mode, so that the GUI continues to update.
6317 Fix e2fsck so that it returns the appropriate exit code when the root
6318 filesystem has been changed, so that system's rc scripts will be told that
6319 the system needs to be rebooted.
6321 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
6322 was set, some of the descriptor blocks that should have been written
6323 out were getting skipped.
6325 Changed e2fsck to force out changes to the backup copies of the
6326 superblock and block group descriptors when important changes are made
6327 to those data structures.
6329 Fix a bug where e2fsck could erroneously mark a filesystem as being
6330 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
6331 introduced in e2fsprogs 1.28.)
6333 If journal debugging is enabled using --enable-jbd-debug, the debugging
6334 level is now set via the E2FSCK_JBD_DEBUG environment variable.
6336 If byteswapping support is disabled using configure --disable-swapfs,
6337 skip the tests which depend on byte-swapping, so that "make check"
6340 Lsattr will now display the indexed directory flag. Also, some of
6341 the more esoteric compression flags are suppressed unless compression
6342 support has been enabled.
6347 E2fsprogs 1.30 (October 31, 2002)
6348 =================================
6350 When resizing a filesystem, and inodes need to moved, resize2fs will
6351 update the inode's ctime field, and the mtime field of the containing
6352 directories, so that incremental backups using dump/restore will work
6355 In order to avoid spurious errors, e2fsck will check the last
6356 superblock write time to determine whether or not it can safely use
6357 the LOW_DTIME checks to determine if there are inodes on the orphan
6358 inode linked list that had somehow gotten disconnected. (Addresses
6359 Sourceforge bug #620980)
6361 Partition in /proc/partitions that being with the string "lvm" are
6362 considered real partitions even if they do not end with a number.
6364 Fixed a bug in the the uuid generation function, where if /dev/urandom
6365 is not present, but /dev/random is, and there isn't sufficient
6366 entropy, the get_random_byte function could spin a loop forever.
6368 E2fsck, mke2fs, etc. will now reliably notice when image files are
6369 mounted using the loopback interface. (Addresses Sourceforge bug
6372 When flushing buffers (as is done by badblocks, for example) check to
6373 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
6374 FDFLUSH ioctl which causes the MD device driver which causes confusing
6375 syslog messages about obsolete ioctl messages. (Addresses Sourceforge
6378 Debugfs's write command now checks to see if the destination filename
6379 exists before creating it. (Addresses Sourceforge bug #478195.)
6381 When installing man pages, search for compressed man pages using all
6382 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
6384 Fixed a bug in fsck where multiple filesystems specified on the
6385 command were not being checked in parallel due to a logic bug
6386 introduced to support the FSCK_MAX_INST environment variable.
6388 We have added a new superblock field, s_mkfs_time, which indicates
6389 when a filesystem was created. It is set via mke2fs, and printed out
6390 by dumpe2fs, but is not actually touched by the kernel.
6392 Dumpe2fs has been made more robust by not aborting if there is an
6393 error reading the block/inode bitmaps; instead it will still print out
6394 the location of the block/inode bitmaps and inode table.
6396 Add support for the an alternative block group descriptor layout which
6397 allows for on-line resizing without needing to prepare the filesystem
6398 in advance. (This is the incompat feature flag meta_bg.)
6400 Add support for storing default mount options in the superblock, so
6401 that the filesystem can be mounted with specific mount options without
6402 needing to specify them on the mount command line or in the /etc/fstab
6405 Add support for a new inode flag, which is to be used for indicating
6406 the top of directory hierarchies for the Orlov block allocator.
6408 Fix e2fsck so that if it creates the lost+found directory, it does so
6409 with the more appropriate permissions of 0700. Also change
6410 mklost+found so that it also creates the directory 0700.
6412 Fixed format bug in e2fsck if NLS is in use.
6414 Add a German translation for e2fsprogs's NLS support.
6416 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
6417 the beginning of the inode table. This won't matter much, since if
6418 there is a bad block at the beginning of the inode table, the root
6419 directory won't be available. But at least e2fsck won't crash in this
6422 Fixed endian problems in the htree code for e2fsck and debugfs.
6424 When byte-swapping a filesystem on a PPC architecture, byte-swap the
6425 bitmaps since the historical big-endian ext2 variant had byte-swapped
6426 bitmaps, and the ext2fs library assumes this. This fixes the
6427 regression test suite on PPC machines.
6429 Fix e2image so that it handles a bad block in the inode table
6432 E2fsck now uses a more sophisticated algorithm to salvage corrupted
6433 directories that recovers more information in the corrupted directory
6436 E2fsck now performs additional consistency checks on indexed (HTREE)
6439 Fix a bug where e2fsck might get confused about whether a completely
6440 empty directory block is an empty leaf block or an interior htree
6441 node. This could cause e2fsck to get confused into think that a valid
6442 indexed directory was corrupted.
6444 E2fsck no longer creates an empty directory entry at the end of a
6445 directory block when optimizing a directory. This would cause some
6446 earlier versions of the dxdir kernel code to corrupt the directory
6447 when attempting to split a node containing an empty directory entry.
6449 E2fsck could sometimes in rare circumstances leave the indexed flag
6450 set after a small directory was optimized by compressing it instead of
6451 indexing it. (This should never happen in real life, since
6452 directories that small wouldn't have been indexed, but better safe
6455 E2fsck now only updates the master superblock in all cases. This
6456 slightly shortens its run time.
6458 Ext2ed can deal with directory entries of length 0; previously it
6459 would get stuck in an infinite loop.
6461 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
6462 specifiers. (Sourceforge patch #613447)
6464 Badblocks will now work correctly on read-only devices such as
6465 CD-ROM's. (Sourceforge patch #600451)
6467 Updated and clarified man pages. (Addresses Debian bug #167108)
6470 E2fsprogs 1.29 (September 24, 2002)
6471 ===================================
6473 Fixed a bug in e2fsck which could corrupt a directory when optimizing
6474 it (via the -D option) or rebuilding the hash tree index with a 1 in
6475 512 probability, due to a fence post error.
6477 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
6480 Mke2fs now enables the directory indexing flag by default. (Since
6481 this is a compatible feature flag, it's safe to do so.)
6483 Tune2fs will support setting the directory indexing feature flag. It
6484 will automatically set up the default hash algorithm and hash seed
6485 fields in the superblock.
6487 If the bone-headed user enters the root filesystem twice in
6488 /etc/fstab, the -R option which skips the root filesystem will skip
6489 all of them. (Addresses Debian bug #159423). Note! This is not a
6490 precedent for dealing intelligently with any other kind of doubled
6491 entry in /etc/fstab!
6497 Removed perror declaration in lib/et/internal.h. All modern systems
6498 can be expected to define perror() these days. Besides, the lib/et
6499 code wasn't using perror at all anyway. :-)
6502 E2fsprogs 1.28 (August 31, 2002)
6503 ================================
6505 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
6506 for setting the htree flag is not included yet, although it can be
6507 manually turned on via the debugfs program.
6509 Clarified e2fsck error message which is printed when it cannot find
6510 sufficient contiguous block when relocating filesystem metadata.
6512 Added support for building an EVMS plugin module for ext2/3. This
6513 module is substantially the same as the EVMS module shipping with EVMS
6514 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
6515 for use with EVMS 1.0 (which did not include the ext2 plugin module),
6516 if the configure --enable-old-evms flag is given.
6518 Fsck will search through EVMS volumes when trying to resolve
6519 filesystem specifications such as LABEL=xxx or UUID=xxx.
6521 Added a new utility program, /sbin/findfs, which will return
6522 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
6525 Update and clarified various man pages. (addresses Debian Bug #145044,
6526 #146437, #131350, #151990, #144621, #141938)
6528 If there are no filesystems specified on fsck's command line, fsck now
6529 treat that as if the -As options were given. Previously it would
6530 simply do nothing. (Addresses Debian Bug #153102)
6532 Mke2fs no longer treats a failure to be able to clear the MD signature
6533 at the end of the filesystem as a fatal error. (Addresses Debian Bug
6536 The e2p library functions (which are used by lsattr and chattr) now
6537 double check to make sure the file is a regular file or directory
6538 before attempting to use the ext2 ioctls. Some device drivers
6539 unfortunately respond to the ext2 ioctl's with unknown behaviour.
6540 (Addresses Debian Bug #152029).
6542 The extended attribute handling has been updated to correspond with
6543 the latest V2 bestbits ACL code.
6545 Fixed bug in e2fsck which caused it to not clear the dtime field when
6546 processing truncated inodes on the orphan list. This could cause data
6547 loss(!) if a filesystem is rebooted before a truncate has been
6550 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
6551 algorithms. This makes e2fsck much faster in the case of severely
6552 corrupted filesystems where a large number of blocks are claimed by a
6553 large number of inodes. (Thanks to the 2.5 IDE device driver for
6554 inspiring this work.)
6556 Resize2fs has been significantly sped up when shrinking and expanding
6557 a filesystem by a very small number of blocks (for example, when EVMS
6558 is converting a partition to be an EVMS legacy volume).
6560 Added a new option to e2fsck, -D, which will optimize or compress all
6561 of the directories in the filesystem.
6563 E2fsck now catches SIGINT and SIGTERM to make sure it will can
6564 properly clean up and only exit at safe points. Fsck will pass
6565 SIGINT/SIGTERM to its child processes, and wait until they have all
6566 exited before it exits.
6568 The uuid parsing code in the uuid library now properly complains when
6569 an illegally formatted uuid is presented to it. (Addresses Debian bug
6572 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
6573 and 2.4.17, since the workaround can cause problems when using a 2.4
6574 kernel with an old version of glibc built with the 2.2 headers.
6576 Fixed a bug in mke2fs where it wasn't properly clearing the initial
6577 superblock used by other filesystems. (Addresses Debian bug #147256.)
6579 Added support for the synchronous directory feature written by Andrew
6582 The debugfs program can delete directories using the rmdir command.
6584 Add support for 8k and 16k filesystems (for systems with page sizes
6585 that are greater or equal to 8k or 16k, respectively). Note that
6586 these filesystems can not be mounted on x86 systems, or other systems
6587 with only 4k page sizes, due to limitations in the current Linux VM
6590 Resize2fs requires that the filesystem state be valid and have no
6591 errors; otherwise, e2fsck -f must be run first. (Previously it simply
6592 required that the last fsck time be greater than the last mount time.)
6594 Configure now defaults the man pages directory to /usr/share/man on
6597 E2fsck now offers to truncate inodes which contain too many blocks (so
6598 that i_blocks would overflow. Also fixed handling of large sparse
6601 E2fsck now more completely checks for symlink validity, including
6602 requiring NULL termination and length checks.
6604 E2fsck will offer to try forcing a disk write to remap a bad block
6605 after finding a read error when reading a filesystem metadata block.
6607 Fixed a bug in debugfs which caused the -b and -s options to crash
6608 debugfs, as well as breaking the testb, setb, and clearb functions.
6610 Added a bmap command to debugfs which calculates the logical to
6611 physical block mapping for a particular inode.
6613 Fixed a bug in code which checked to see if a device was mounted which
6614 sometimes (rarely) failed in the case of a plain file.
6616 Fixed a bug in resize2fs where when it reported an error, it would
6617 print a message erroneously indicating that the filesystem had been
6618 resized before it aborted.
6620 When resizing a plain file which is smaller than the requested size,
6621 resize2fs will attempt to extended the file so that programs like
6622 e2fsck will not complain that the file is too small.
6624 Resize2fs will print the actual new size of the filesystem when it is
6627 Fixed a bug in debugfs where "ls -l" would report incorrect file type
6628 information on big-endian systems.
6634 Fixed collisions with C++ reserved words.
6636 Added portability fixes for building e2fsprogs on the HURD and AIX.
6638 Added the ext2ed program for creation of test cases. (ext2ed has many
6639 limitations and bugs which make it unsuitable for production use.)
6641 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
6642 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
6643 name_len field is byte swapped on big-endian machines, since in the
6644 V2 structure, name_len is a char field which is doesn't need to be
6645 byte swapped --- except if an old-style kernel had byte-swapped the
6646 name_len field as part of the V1 structure.
6649 E2fsprogs 1.27 (March 8, 2002)
6650 ==============================
6652 The warning messages for mke2fs now go to standard error.
6654 Fixed to make sure "make check" runs all of the test programs with
6655 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
6657 The mke2fs program checks the boot sector for the BSD disk label, and
6658 avoids erasing it if it is there.
6660 Fixed a bug in e2fsck which caused it to core dump if the journal
6661 inode was missing when it was supposed to be there.
6663 E2fsck now prints ranges in pass 5 when printing deltas for the block
6666 Debugfs's "ls -l" command now will print out the file type information
6667 in the directory entry.
6669 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
6670 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
6672 Debugfs can now examine the experimental directory indexing
6675 Fixed bug in debugfs which caused it to core dump if modify_inode is
6676 called without an open filesystem.
6678 The debugfs lsdel command now runs its output through a pager first.
6680 When installing manual pages, remove the compressed manual pages first.
6682 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
6684 Fix the 2.4 resource limitation workaround introduced in 1.26 which
6685 actually broke things on mips32, sparc32, and Alpha platforms.
6687 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
6688 (which is required by the newer libintl libraries).
6693 Fixed various gcc -Wall complaints.
6695 Fixed a few memory leaks in the e2fsck journalling code, and in the
6696 ismounted code checking for a swap device.
6698 Add new inode I/O abstraction interface which exports an inode as
6701 Exported ext2_file_flush as a public interface.
6703 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
6705 Lots of small random portability fixes to make e2fsprogs build under
6706 AIX --- even without the 5L compatibility toolkit, and even using the
6707 uber-crippled AIX native C compiler.
6710 E2fsprogs 1.26 (February 3, 2002)
6711 =================================
6713 Dumpe2fs will keep going now if the bad block inode can't be read.
6714 (Previously it stopped with a fatal error.)
6716 E2fsck will now give an opportunity to run the journal even if the
6717 recovery flag is not set. This is the default behaviour if e2fsck is
6718 using a backup superblock, since the needs_recovery flag will never be
6719 set in the backup superblock copies.
6721 E2fsck now automatically finds the backup superblock/group descriptors
6722 even when the primary superblock is completely destroyed for 2k and 4k
6723 filesystems. (Previously it just guessed/assumed that we were dealing
6724 with a 1k filesystem in that case, and users had to manually specify
6725 the backup superblock number.)
6727 Fixed a bug in e2fsck where it dereferences a null pointer when there
6728 is a problem opening a filesystem in preen mode.
6730 E2fsck now handles external journals correctly; previously it trashed
6731 the external journal device if the journal needed to be replayed.
6733 Work around ulimit incompatibility problem caused by recent 2.4
6734 kernels; the unix IO module will automatically try to set any resource
6735 limits to be infinite on startup.
6737 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
6738 bitmap if it wasn't present and the blocksize was 2k or 4k.
6739 (Addresses Debian Bug #116975)
6741 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
6742 clearing the new V2 fields if they do not make sense or if the ext3
6743 superblock is version 1 superblock.
6745 E2fsck will automatically relocate the ext3 journal from a visible
6746 file (i.e., /.journal) to an hidden inode if the filesystem has been
6747 opened read/write. This allows the users to add a journal while the
6748 filesystem is mounted, but the next time the system is rebooted, the
6749 journal file will disappear. This avoids problems with backups,
6750 stupid operators with superuser bits, etc.
6752 Fix a bug in fsck where it would not support a filesystem type of
6753 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
6755 Fsck now supports fstab entries of the form "ext3,ext2". It will also
6756 automatically identify reiserfs filesystems.
6758 The number of processes spawned by fsck can now be limited using the
6759 FSCK_MAX_INST environment variable.
6761 Fsck now searches the LVM proc hierarchy to find logical volumes which
6762 should be searched for UUID and label information.
6764 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
6765 limit if at all possible, when opening a block device. (The filesize
6766 limit shouldn't be applied against writes to a block device.)
6768 In mke2fs and e2fsck, specifying the -c option twice will now do
6769 a read/write test on the disk. Update the man pages to encourage
6770 using the -c option, and to discouraging running badblocks separately,
6771 since users tend to forget to set the blocksize when running
6774 Mke2fs now automatically clears the immutable attribute on a
6775 pre-existing .journal file left over from a previous failed attempt to
6776 add a journal to an already-mounted filesystem.
6778 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
6781 Mke2fs now creates the lost+found directory with permissions of 0700,
6782 so that files that had previously lived in protected directory are
6783 safe if they get dropped in lost+found and the system administrator
6784 doesn't deal with immediately. (Addresses Debian #bug 118443)
6786 Mke2fs and e2fsck (and all programs that use the
6787 ext2fs_check_if_mounted function) will now properly identify that a
6788 device is mounted, even in cases where devfs has confused things with
6789 multiple devices names with the same identity, or if a dim-witted
6790 system administrator has done something stupid like creating device
6791 file aliases in their home directory. Also now checks for swap devices
6792 by using /proc/swaps. (Addresses Debian bug #106622)
6794 Added a new option (-T) to tune2fs which sets the time a filesystem
6797 Speed up e2image when creating sparse raw image files by optimizing
6798 away excess lseek() system calls.
6800 Fix support of large (> 2GB) files when used as a filesystem in
6801 mke2fs, tune2fs, debugfs, and findsuper.
6803 Debugfs's stat and icheck commands now properly deals with large (>
6806 Debugfs's set_super_value command now prints out the list of valid
6807 superblock fields which can be set using the command.
6809 Debugfs's rm and kill_file command now updates the superblock free block
6810 and inode counts, thus keeping the filesystem consistent.
6812 Debugfs's lsdel command now takes an optional argument which allows
6813 the user to only see the most recently deleted files.
6815 A new command (undel) was added to debugfs which automates
6816 undeleting a deleted inode and linking it back to a directory.
6818 Debugfs's ls command now takes a new option, -d, which lists
6819 deleted directory entries.
6821 Debugfs's testb, freeb, setb, and find_free_block commands now take an
6822 optional count argument.
6824 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
6825 be used to signal that a particular inode should not be eligible for
6826 tail-merging --- this is needed for programs like LILO.
6828 The findsuper (an unreleased, uninstalled utility program) has been
6829 improved to add extra validity checks and to add a progress meter.
6830 (It is still an unsupported program; the officially supported way to
6831 recover from a trashed partition table is to use gpart; findsuper is
6832 for wizards only. :-)
6834 Debugfs was fixed to compile with "configure --disable-swapfs".
6836 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
6838 Added new translation file for Turkish.
6843 Fix general gcc -Wall complaints.
6845 E2fsprogs (mostly) works with the dietlibc.
6847 The programming texinfo file has been expanded to include description
6848 of additional libext2fs functions. (Still not completely done, but a
6849 lot of the more important functions have been documented.)
6851 Added a umask structure to struct_ext2_filsys, which currently only
6852 modifies the behaviour of ext2fs_mkdir(), but if we add any file
6853 creation functions to libext2fs, we should also make sure they respect
6856 The build-rpm script was fixed to be a bit more safe.
6858 The tests' Makefile now has a way of automating test case creation
6859 for e2fsck, using "make testnew".
6861 Created a new function, ext2fs_dir_iterate2 which passes more
6862 information to the callback function (identical to the one used by
6863 ext2fs_dblist_dir_iterate). The directory iterator functions take a
6864 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
6865 directory entries. If the directory entry is deleted, the callback
6866 function will be called with the entry parameter set to
6867 DIRENT_DELETED_FILE.
6869 Added new functions, ext2fs_inode_alloc_stats and
6870 ext2fs_block_alloc_stats, which takes updates block/inode allocation
6871 statistics in the bitmaps, block group descriptors, and superblock
6872 when inodes or blocks are allocated or deallocated.
6875 E2fsprogs 1.25 (September 20, 2001)
6876 ===================================
6878 This is primarily a bug-fix release; no new features were added, but
6879 there are a number of embarrassing bug fixes and cleanups applied.
6881 Fix a bug mke2fs which causes stack garbage to be written to disk when
6882 zapping disk sectors. (This bug could cause mke2fs to core dump for
6883 some kernels, I suspect with security enhancement patches.)
6885 Remove unneeded #include of <linux/config.h> which was breaking
6886 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
6888 Updated tune2fs man page to reflect the fact that adding or removing a
6889 journal doesn't require running e2fsck.
6891 Remove use of AC_REQUIRE from autoconf which had been used to prevent
6892 AC_CANONICAL_HOST from being called twice; unfortunately this causes
6893 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
6894 used outside of autoconf macros. Fortunately, it doesn't seem to be
6895 necessary any more, anyway.
6897 E2fsck will now not fall back to an alternate superblock if the user
6898 specifies the superblock location explicitly on the command-line.
6899 This allows easier recovery from a situation where the primary
6900 superblock and block groups are slightly corrupted, but the backup
6901 superblocks are completely broken.
6903 Fix problem which caused compile_et and mk_cmds to blow up if
6904 e2fsprogs was in a directory with a pathname that contained spaces.
6906 We are now more paranoid about checking the entry in /etc/mtab to make
6907 sure the filesystem is really mounted, since some broken distributions
6908 (read: Slackware) don't initialize /etc/mtab before checking non-root
6909 filesystems. (Slackware also doesn't check the root filesystem
6910 separately, and reboot if the root filesystem had changes applied to
6911 it, which is dangerous and broken, but there's nothing I can do about
6914 Make UUID library C++ friendly by adding appropriate extern "C"
6915 declarations and using const in the function declarations.
6917 Fix up the com_err texinfo file so that it can product a valid info
6918 file (previously, it could only be used to generate paper
6919 documentation using texinfo.tex).
6922 E2fsprogs 1.24a (September 2, 2001)
6923 ===================================
6925 Fix brown-paper bug in mke2fs which caused it to segfault when
6926 printing the version string.
6929 E2fsprogs 1.24 (August 30, 2001)
6930 ================================
6932 Revert the BLKGETSIZE64 support, since for some distributions, this
6933 ioctl has been used by an unofficial kernel patch to update the last
6934 sector on the disk, and this was causing disk corruption problems as a
6937 Mke2fs is now more careful about zapping swap space signatures and
6938 other filesystem/raid superblock magic values so that programs like
6939 mount who try to use heuristics to determine the filesystem type of a
6940 partition are less likely to be confused.
6942 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
6943 regular file (since Andreas Dilger's on-line resizing tools will set
6946 Fixed some minor texinfo, man pages nits for spelling errors,
6947 texinfo warnings, etc. (Addresses Debian bug #110621.)
6949 E2fsprogs program no longer print the filesystem version number
6950 (i.e. 0.5b), since it only confuses people and doesn't serve any real
6953 E2fsck will once again compile under libc5, since it will supply its
6954 own version of strnlen if necessary.
6956 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
6957 when specifying the external journal device. tune2fs will also search
6958 devices looking for the external journal device when removing it.
6960 E2fsprogs 1.23 (August 15, 2001)
6961 ================================
6963 Add initial support for extended attributes (EA); e2fsck will
6964 correctly handle a filesystem with EA's and check the EA blocks for
6967 E2fsck's symlink sanity checking has been cleaned up. It now checks
6968 the i_size value of fast symlinks, and checks for immutable flags
6969 being set of symlinks, etc.
6971 E2fsck now offers to clear inodes which are special files that have a
6972 non-zero i_blocks or i_size field. (The i_size field check was in the
6973 previous version of the code, but due to a bug it didn't offer to
6974 clear the inode unless i_size and i_size_high were both non-zero.)
6976 E2image can now create "raw" image files, which only contain the
6977 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
6978 debugfs, etc., can be run directly on the raw image file.
6980 Add support for the 64-bit block device patches.
6982 Fixed bugs in creating external journals with a 1k blocksize.
6984 Add initial support for external journals (so long as the external
6985 journal only supports a single filesystem) in e2fsck.
6987 Remove requirement for needing to run fsck on a filesystem after
6988 removing a journal (either internal or external).
6990 The man pages now document how to create and manage external journals.
6992 Speed up the check of an ext3 filesystems by avoiding a needless flush
6993 of all of the superblock and block group descriptors.
6995 Speed up creating an internal journal using tune2fs in the case where
6996 the filesystem has a lot blocks already allocated.
6998 Tune2fs has been fixed to make sure that only error messages go to
6999 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
7001 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
7002 now not set the sparse_super feature. (Addresses Debian bug #108165)
7004 Add support in fsck for the filesystem type "auto".
7006 Fsck -A will not try to interpret device names for filesystems which
7007 have a pass number is 0. (Addresses Debian bug #106696).
7009 Fsck prints a warning message if now valid filesystems are passed to
7010 it. (Addresses Debian Bug #107458.)
7012 E2fsck now gives an explicit warning if there filesystem still has
7013 errors at the end of the run. (Addresses Debian bug #104502)
7015 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
7016 reflects an error. E2fsck will also not run the orphan list if the
7017 filesystem contains errors, since the orphan list might be corrupted.
7019 E2fsck now prints the number of large files when given the -v option.
7021 Fixed minor memory leaks in e2fsck.
7023 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
7026 E2fsprogs 1.22 (June 22, 2001)
7027 ==============================
7029 Fixed a bug in e2fsck's handling of orphan inodes which are special
7030 files (i.e., block/character device files, named FIFO's, etc.).
7032 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
7033 tune2fs to fail at adding a journal to a mounted filesystem.
7035 Fixed a few big-endian bugs in e2fsprogs
7036 * The directory block functions were accidentally reporting
7037 some directories as corrupted when they weren't.
7038 * If e2fsprogs is compiled --disable-swapfs, the C language
7039 equivalents weren't being included for big-endian platforms.
7040 (Fixes Debian bug #101686).
7042 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
7047 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
7048 ioctls, and allow them to be defined for non-i386 platforms.
7050 The uuid.h header file is now protected against multiple inclusions.
7052 E2fsprogs is now being developed using BitKeeper. Changed the test
7053 scripts to deal with BK's stripping CR characters from text files,
7054 and changed the top-level Makefile.in to avoid including BitKeeper
7055 files when generating the source tarball.
7058 E2fsprogs 1.21 (June 15, 2001)
7059 ==============================
7061 Added new configure flags which allow a subset e2fsprogs to be built;
7062 this is most useful for boot floppies, since the resulting shared
7063 libraries and programs are slimmed down by removing features that
7064 aren't necessary for a boot floppy. The new flags that were added
7065 are: --disable-swapfs, which removes support for byte swapping old
7066 legacy PPC/68k filesystems, --disable-debugfs, which removes support
7067 for debugfs from the libext2fs library, --disable-imager, which
7068 removes support for the e2image program, and --disable-resizer, which
7069 removes support for resize2fs.
7071 E2fsck now prints the number of mounts or days elapsed since the last
7072 check when e2fsck is forced to check an otherwise clean filesystem.
7074 Tune2fs now prints an informative message about how often a filesystem
7075 will be checked when adding a journal to the filesystem, to remind the
7076 user that he/she may want to adjust those parameters using tune2fs
7079 Worked around hurd brain-damage which causes e2fsck to sometimes
7080 believe a filesystem is the root filesystem based on device numbers
7081 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
7084 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
7085 erroneous error with the -F option was specified.
7087 Fixed a ext3 recovery bug in the revoke handling; synchronized with
7090 Fixed two bugs in e2fsck's handling of dup block handling, dealing
7091 with relatively uncommon edge cases: a directory with an indirect
7092 block which is claimed by another file, and when the last inode in the
7093 filesystem has blocks claimed by another file.
7095 E2fsck now checks to see if the i_size field of a fast symlink is too
7096 big, and offers to clear the symlink if so.
7098 E2fsck now checks to see if i_size_high of special files is non-zero,
7099 and offers to clear i_size_high.
7101 Fix e2fsck's handling of incompatible journal flags so that the user
7102 has chance to abort, and then has the option to clear out the journal
7103 entirely. (Addresses Debian bug #98527.)
7105 Fixed a bug in fsck which could cause it to core dump if a mix of
7106 standard and non-standard device names are used in /etc/fstab.
7107 (Debian bug #100559)
7109 Fixed a bug in debugfs which caused read errors when copying a file to
7112 The debugfs set_super_value command can now modify the s_lastcheck field.
7114 Fixed a bug in lsattr and chattr which was accidentally introduced in
7115 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
7116 directories correctly because the change modified the layout of struct
7117 dirent to be incompatible with the libe2p shared library.
7119 Cleaned up the mke2fs manual page and included a discussion about why
7120 it's good to periodically check the filesystem even when journalling is
7126 Fix general gcc -Wall complaints.
7128 The types needed by the ext2 header files are now provided by
7129 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
7131 Integers are now preferred to longs when trying to find a 32-bit type
7132 in ext2_types.h. Also, if linux/types.h has already been defined,
7133 don't try to redefine the types.
7135 Fixed make depend script so that it automatically corrects the
7136 pathname cleanups performed by make -M, so I don't have to fix them up
7139 Fixed the d_loaddump test case to be more robust, and not depend on
7142 Removed debugfs's dependence on pread(), which was accidentally
7143 introduced in e2fsprogs 1.20
7145 Fixed a performance bug in the libext2fs's icount routine; the size
7146 estimate of the icount array was incorrectly being calculated.
7148 Removed use of the badblocks compatibility functions in the e2fsprogs
7151 Added paranoia code which protects against strange cases where /etc
7152 isn't on the root filesystem, or if /etc/mtab doesn't exist.
7154 The header file ext2_types.h is now installed.
7156 Autoconf is used to determine when we are on big-endian machines,
7157 instead of doing run-time tests, to save a few bytes of code.
7159 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
7160 functions are no longer inline functions, which saves space and
7161 doesn't really cost any real performance.
7163 The ext2fs library no longer depends on the e2p library. (What need
7164 there was of it --- namely, fsetflags, was coded in-line).
7166 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
7167 when the user is stupid and tries compiling the package using "make
7170 Miscellaneous code cleanups:
7171 * Added missing files from Makefile.in's SRCS file, so that
7172 their dependencies would be properly calculated.
7173 * Removed redundant code
7174 * Fixed comments in code
7175 * Removed no-longer needed argsused #pragma.
7178 E2fsprogs 1.20 (May 20, 2001)
7179 =============================
7181 Add support for replaying the ext3 journal purely in user mode,
7182 including handling the orphaned inode list. Used code contributed by
7183 Andreas Dilger, with bug fixes and the orphaned inode handling done
7186 The mke2fs and tune2fs programs can create or modify a filesystem to
7187 include an ext3 journal. Tune2fs also can be used to remove an ext3
7188 journal from a filesystem.
7190 E2fsck will now check for the existence of a linked list of orphan
7191 inodes in the superblock, and clear those inodes before starting the
7192 rest of the filesystem check (but after the journal playback).
7194 E2fsck now validates the file descriptor passed to the -C option,
7195 which saves against the completion bar getting written to an
7196 unexpected location, such as the disk being checked. (Debian
7197 bug/wishlist #55220)
7199 E2fsck will now bump the filesystem revision number from zero to one
7200 if any of the compatibility bits are set.
7202 Fixed a bug where a badly corrupted directory on a big endian system
7203 could cause e2fsck to die with a bus error. The
7204 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
7205 the ext2 library now does alignment sanity checks on the rec_len field
7206 of the directory entry before using it.
7208 The ext2 library has been enhanced to make tune2fs safe to run on
7209 mounted filesystems. (Users could usually get away with using tune2fs
7210 on mounted filesystems before, but with the advent of ext3 and
7211 journalling, it became important to make tune2fs was *really* safe for
7212 use even when the filesystem being modified is mounted.) E2label is
7213 now implemented by tune2fs using an argv[0] dispatch, so that e2label
7214 is also now safe for use on mounted filesystems.
7216 Added a new program, e2image, which creates a backup of critical ext2
7217 filesystem data structures. The generated image file can be examined
7218 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
7219 the image file to help recover very badly damaged filesystems.
7221 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
7222 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
7223 large file when deciding whether or not the filesystem has large files.
7225 Fixed lsattr and chattr so that they work correctly on large files.
7226 (Fixes Debian bug #72690.)
7228 Removed limitation in get_device_size() which imposed a one terabyte
7229 filesystem limitation. (Most 2.2 kernels still have a signed int
7230 problem which cause 1 TB block device limitation. Fortunately, the
7231 kernel patches to fix this are much easier than fixing the 2TB
7232 limitation in the kernel. :-)
7234 A max_mount_count of zero is now treated as if no mount count were
7235 set. (Previously, no mount count was indicated by using -1, and a
7236 mount count of zero caused e2fsck to always be run.)
7238 Mke2fs supports two new filesystem types largefile and largefile4.
7240 Mke2fs now adds some randomness in s_max_mount_count so that multiple
7241 filesystems won't be all checked at the same time under normal
7244 Fixed bug in the progress bar printing code which could cause e2fsck
7245 to core dump on an illegal filesystem.
7247 Fixed bug in fsck which could allow more than one instance of e2fsck
7248 to be printing a progress bar. (Debian bug #65267)
7250 Fsck using a UUID or a LABEL specifier will work even if devfs is
7251 compiled into the kernel and not mounted. If the pathnames in
7252 /proc/partitions are incorrect, fsck will search /dev for the correct
7253 device (using the new ext2fs_find_block_device library function).
7254 Fsck now also checks the RAID devices first so that they are properly
7255 found when they are in use. Support has also been added to support
7256 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
7258 Fixed a bug in fsck which caused it not deal properly with 16
7259 byte long filesystem labels.
7261 Fsck's -t option has been made a lot more flexible. The semantics for
7262 what happens if a comma-separated list to fsck has been regularized,
7263 and it is now possible to filter what filesystems will get checked
7264 based what is in the filesystem's fstab entry's option field. (Debian
7267 The dumpe2fs program can now print out the group description
7268 information in hex, and also prints the location of the superblock and
7269 block group descriptor for those block groups that have them.
7271 Mke2fs now clears the ext2 superblock before it starts creating a
7272 filesystem, so that the superblock magic number is only written if the
7273 filesystem creation process successfully completes.
7275 The debugfs program's stat command now pretty-prints the blocks used
7276 by an inode so that it's more compact and informative.
7278 The debugfs stats command now uses the same libe2p code (which is used
7279 by dumpe2fs) to print the superblock header information. This is more
7280 complete, and it avoids a bit of code duplication.
7282 Added a new debugfs command, set_super_value (ssv) which allows the
7283 user to set arbitrary superblock fields.
7285 Debugfs was extended to support inode numbers in hex (by prefixing
7286 them with 0x), and so that modify_inode can set the inode generation
7287 number. Also, there is now a new function command called logdump
7288 which will dump an ext3 journal.
7290 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
7293 Debugfs's dump command now stops immediately upon reporting a disk
7294 read error. (Fixed a bug in ext2fs_file_read library routine which
7295 caused debugfs not to stop.) (Debian bug #79163)
7297 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
7298 checked before /etc/mtab is used, since /proc/mounts is more likely to
7301 Added portability fixes for Solaris and Linux/ia64.
7303 Various manual pages were clarified and cleaned up. (Fixed debian
7304 bugs #63442, #67446, and #87216)
7310 The e2fsck message printer now supports %Iu and %Ig, which will print
7311 out the inode's user and group owners, respectively.
7313 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
7314 that no longer dependent on the system having the correct version of
7315 the kernel header files.
7317 Added a new function to libext2, ext2fs_find_block_device(), which
7318 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
7319 device given its device number.
7321 Added a new function to libext2, ext2fs_sync_device, which centralizes
7322 all of the places which might try to use the BLKFLSBUF or FDFLUSH
7323 ioctls (and usually failing to define them since the system header
7324 files don't usually do this for us, and we're trying to avoid usage of
7325 kernel include files now).
7327 Added new utility programs in tests/progs: random_exercise and
7328 hold_inode. They aren't built by default; they're useful for
7329 exercising ext3 filesystem code.
7331 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
7332 the filesystem close functions to only update the superblock, and to
7333 not touch the block group descriptors. Needed by tune2fs when
7334 modifying a mounted filesystem.
7336 Got rid of struct ext2fs_sb and replaced it with the standard struct
7337 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
7338 source (but not binary) compatibility of some users of the ext2
7339 library. Those applications should just simply do a global search and
7340 replace of struct ext2fs_sb with struct ext2_super_block, and include
7341 the new header file <ext2fs/ext2_fs.h> which defines it.
7343 The ino_t type has been renamed ext2_ino_t to protect applications
7344 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
7345 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
7346 unexpected ABI change.
7348 The Makefiles have been reworked so that "make check" can be run from
7349 the top-level Makefile.
7351 Fix general gcc -Wall complaints and removed dead code.
7353 Remove use of NOARGS, because we assume everyone does ANSI C these
7356 Added build-rpm script from sct.
7358 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
7361 New function ext2fs_flush_icache which must be called if the
7362 application program modifies the inode table blocks without going
7363 through ext2fs_write_inode() interface.
7365 New ext2fs_check_mount_point() function, which will return the mount
7366 point of a device if mounted.
7368 The io_channel abstraction now has an optional interface,
7369 io_channel_write_range, which allows specific byte ranges to be
7372 The unix_io IO channel now supports write-through caching, so that
7373 journal creation is more efficient.
7375 Added x86 assembly language routines to support byte swapping, to
7376 reduce executable size.
7378 Fixed bug in the utility program subst so that it's possible to
7379 replace a substitution variable with a zero-length string.
7381 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
7382 slipped into some of the problem number.
7384 E2fsprogs 1.19 (July 13, 2000)
7385 ==============================
7387 Release the resize2fs program since the timeout before it could
7388 be released under the GPL has finally expired.
7390 Add experimental support needed for the ext2 compression patches.
7391 This requires compiling e2fsprogs with the --enable-compression flag
7392 to the configure script.
7394 Added ext3 journalling support. E2fsck will run the journal (if
7395 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
7396 installed as a symlink to e2fsck. Fsck has been taught about ext3,
7397 and treats it the same as ext2 in terms of the progress bar logic.
7398 Dumpe2fs will display the superblock journalling information if the
7399 filesystem has a journal. The ext2 library will now permit opening an
7400 ext3 filesystem with the recovery flag set. This is necessary for
7401 on-line dump's to work correctly, but there may be issues with this
7402 working well since ext3 is much less aggressive about syncing blocks to
7403 the filesystem, since they're safe on the journal.
7405 Tune2fs and e2fsck have been changed to allow the mount_count check to
7406 be disabled by setting max_mount_count to -1. (This was already
7407 supported by the kernel.)
7409 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
7410 are used for ext3 as well.
7412 Added internationalization support for e2fsprogs; must be enabled
7413 by passing --enable-nls to configure.
7415 Always use the provided ext2fs header files to insulate ourselves from
7416 kernel version changes. Which include files are used by e2fsprogs
7417 have also been cleaned up to improve portability.
7419 Limit the number of times that e2fsck updates the progress bar so that
7420 people who are booting using a 9600 baud console don't get swamped by
7423 Improved the loop detection algorithm in e2sck's pass #3 so that it is
7424 much, much faster for large filesystems with a large number of
7427 The memory footprint for e2fsck is now slightly smaller than before.
7429 E2fsck now checks if special devices have a non-zero size, and offers
7430 to clear the size field if it finds such an inode.
7432 E2fsck now checks if special devices have the append-only flag set,
7433 and offers to clear the inode.
7435 E2fsck now properly handles some "should never fail" cases during a
7436 bitmap copy in pass5.
7438 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
7440 E2fsck now calculates the correct location of the backup superblock in
7441 the case of filesystem blocksizes > 1k.
7443 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
7444 which normally didn't cause problems under most filesystem parameters,
7445 but could cause a valid superblock to be rejected in extreme cases.
7446 Other checks for validating superblock values were made more
7449 Added non-destructive write testing to the badblocks program, courtesy
7450 of David Beattie. The badblocks also now has an option to input the
7451 current set of bad blocks, so that known bad blocks are skipped to
7452 speed up the badblocks test. There is also a persistent rescan
7453 feature which causes badblocks to run until it has completed some
7454 number of passes without discovering any new bad blocks.
7456 Badblocks now checks to see if the device is mounted and refuses to do
7457 the tests involving writing to the device if it is mounted. Also,
7458 badblocks now allows the number of blocks to be checked to be
7459 defaulted to the size of the partition.
7461 Fixed a bug in fsck which didn't allow non-root users to be able to
7462 check filesystems if there were any LABEL= or UUID= entries in
7465 The Hurd doesn't support the filetype filesystem feature. The mke2fs
7466 program now makes sure that for the Hurd, the filetype feature is
7467 turned off. E2fsck will check to see if the filetype feature is
7468 turned on for Hurd filesystems, and offer to turn off the feature.
7470 Mke2fs now has a safety check to make sure the number of blocks do not
7471 exceed 32 bits even on a 64 bit platform.
7473 Really fixed a bug in fsck to allow "fsck -As" to run interactive
7474 fsck's. (For those people who like to do interactive fsck's in the
7477 Debugfs has a few new features: the rdump command, which will do a
7478 recursive dump of a directory and all of its contents, and the lcd
7479 command which does a local chdir (much like the ftp command of the
7480 same name). In addition, the debugfs program and the open_filesystem
7481 command now takes three new options: -b and -s, which allows the
7482 blocksize and superblock location to be specified, and the -c option
7483 which is used in catastrophic situations where the block group
7484 descriptors are corrupt. If the -c option is specified, debugfs will
7485 skip trying to read in the block and inode bitmaps.
7487 Debugfs's lsdel command was fixed to handle bad blocks in the inode
7490 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
7493 General improvements in error messages
7495 - Mke2fs prints a sane error message if the partition size is zero
7496 (usually because the partition table wasn't reread by the
7497 kernel due to the partition being busy), instead of "invalid
7498 argument passed to ext2 library while initializing superblock".
7500 - Fsck now prints more self-explanatory message if an invalid UUID=
7501 or LABEL= specification is passed to it.
7503 UUID library changed to use the LGPL.
7505 Fixed a bug in the UUID library where very rapid calls to the
7506 time-based UUID generator could cause duplicate UUID's to be returned.
7507 This was not a problem for e2fsprogs, but it could be a problem for
7508 other users of the library.
7510 Make the UUID library more robust in the face of missing or an
7511 improper /dev/urandom or /dev/random files.
7513 Added some random portability fixes for Solaris.
7515 Some minor man page updates.
7517 Fixed a memory leak in the ss library.
7523 We now try to use lseek64 and open64 from the LFS if possible.
7525 The 3rd parameter in e2p's print_flags is now a flags word, instead of
7528 The mark and unmark bitmap functions now return the previous state of
7529 the bit that was being changed, which is useful for some speed
7532 The following functions have been added to enhance the badblocks list
7533 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
7534 ext2fs_badblocks_equal.
7536 The ext2 header files now have the latest journalling fields to the
7539 The ext2fs_mkdir function in libext2fs now properly backs out of error
7540 conditions robustly.
7542 Cleaned up makefiles:
7543 - to cleanly compile with the -j flag.
7544 - so distclean removes all generated files.
7545 - so in case of an error while installing header files, the make aborts.
7547 Fix test_script so that it works correctly when compiling in the
7550 The random UUID generation routine has been made slightly better in
7551 the case where /dev/random doesn't exist. (Use of randomly-based UUID
7552 is still not recommended if /dev/random doesn't exist, however; it's
7553 better to use the time/ethernet MAC address UUID in this case.)
7555 Clean up the build process so it's more friendly in case of missing
7558 The ext2fs header file can now be #include'd into C++ programs.
7560 The e2p.h header file is now installed.
7562 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
7566 E2fsprogs 1.18 (November 10, 1999)
7567 ==================================
7569 Fix a core dumping bug in e2fsck if an imagic inode is present or
7570 (more rarely) if the filesystem is badly corrupted enough that e2fsck
7571 has to restart pass 1 processing. E2fsck now closes the filesystem
7572 before freeing a large number of its data structures, so in the case
7573 of future memory faults, at least the fixed filesystem will be fully
7576 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
7577 imagic inode, it will offer to clear the imagic flag.
7579 E2fsck will now offer to clear the immutable flag on special files
7580 (device/socket/fifos) when running it in non-preen mode.
7582 E2fsck will now set the filetype when creating /lost+found, and when
7583 connected orphaned inodes to /lost+found.
7585 Debugfs's ncheck and icheck commands now handles the case where there
7586 are bad blocks in the inode table without bombing out.
7588 The badblocks list processing code has been made more efficiently for
7589 appending a large number of (ordered) badblocks to the badblocks list.
7591 Some minor man page updates.
7593 Fsck now allows interactive e2fsck's when using fsck -As (not a common
7594 mode, but some people like to do this in boot scripts for silly reasons).
7599 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
7600 with the problem code convention.
7602 The badblocks list regression test program has been updated to work
7603 with previously made API name changes.
7605 The ext2fs_free() command now uses the new badblocks API to avoid
7606 using the compatibility layer.
7608 Added new regression test cases; the run_e2fsck test script now
7609 supports the ability for a test case to run a preparatory command
7610 before running e2fsck.
7612 E2fsprogs 1.17 (October 26, 1999)
7613 =================================
7615 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
7618 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
7619 thus potentially causing problems if a binary UUID contained a NULL
7622 E2fsck now uses stricter checks for directory entries in pass 2:
7623 zero-length filenames are not allowed; neither are 8 byte long
7626 The debugfs "dirty" command now clears the filesystem valid bit.
7627 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
7628 bit in the in-core superblock image. The new functionality is more
7629 what the user expects, and is more useful.)
7631 Added a debugging hook to test parallel fsck; if the environment
7632 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
7633 will be checked in parallel when they normally would not be.
7638 Fixed some #ifdef's for compilation under the Hurd OS.
7640 Fixed minor W2K compatibility problems.
7642 Fixed some miscellaneous GCC warnings.
7645 E2fsprogs 1.16 (October 22, 1999)
7646 =================================
7648 Fixed a race condition bug in fsck; when printing a progress bar, if
7649 checking multiple filesystems in parallel, it was possible for fsck to
7650 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
7651 handler, which would cause it to terminate with a signal 10.
7653 E2fsck now properly handles filesystems that have the
7654 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
7655 filesystem into using or not using FILETYPE feature.
7657 E2fsck now properly handles filesystems that have the IMAGIC feature
7658 turned on (this is used on Linux AFS servers).
7660 The mke2fs program now creates filesystems that have the filetype and
7661 sparse_superblock features enabled by default, unless it is run on a
7662 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
7663 so there is now a new flag -O which allows the user to specify with
7664 which features she would like to create the filesystem; "mke2fs -O
7665 none" will create a filesystem compatible with 2.0 kernels.
7667 The tune2fs program now has a -O option which allows the user to set
7668 and reset "safe" filesystem features. Currently, the only ones which
7669 allows to be modified are the filetype and sparse_superblock features.
7670 Note setting or clearing either feature will require running e2fsck on
7671 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
7672 requires that there is enough free space on the filesystem for the
7673 extra superblocks which will be created by e2fsck.)
7675 Debugfs can now set and print filesystem features in the superblock
7676 using the "features" command. Dumpe2fs will print out the complete
7677 set of features when listing the superblock.
7679 Dumpe2fs has new options -f (force) and -h (header-only).
7681 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
7682 message to come up. This could happen when decrementing or
7683 incrementing a link count could result in an overflow.
7685 Fixed a bug in e2fsck where the block count on the lost+found
7686 directory would not be properly incremented when the directory was
7687 expanded to the point where an indirect block needed to be allocated.
7689 E2fsck now makes some additional sanity checks on the superblock to
7690 avoid crashing or giving a memory allocation error if some of the
7691 values in the superblock are unreasonable (but the superblock otherwise
7694 Fixed a bug in e2fsck where a very badly corrupted filesystem might
7695 require two passes to completely fix the filesystem. This happened if
7696 an inode claimed blocks that was part of the filesystem metadata
7697 (typically, when garbage was written into an inode table or indirect
7698 block, since this kind of filesystem corruption normally doesn't
7701 On the Alpha, glibc declares st_flags although it isn't actually used;
7702 the configure script was improved to detect this case so that
7703 e2fsprogs can avoid using the non-functional stat field.
7705 The manual pages were updated to use a more consistent formatting
7706 style consistent with standard Unix man pages. Mke2fs's man page
7707 added documentation for a few previously undocumented options.
7709 Fixed minor display bugs in tune2fs and mke2fs.
7714 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
7716 Added features to parse and print feature strings into the e2p library.
7717 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
7719 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
7720 whose directory entries contain proper filetype information if the
7721 filesystem supports it.
7723 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
7724 the directory entry filetype information. This is used to set the
7725 directory entry filetype information if the filesystem supports it.
7727 Fixed a bug in ext2fs_expand_dir() where the block count in a
7728 directory's inode would not be properly incremented when the directory
7729 was expanded to the point where an indirect block needed to be
7733 E2fsprogs 1.15 (July 18, 1999)
7734 ==============================
7736 Add configuration checks so that e2fsprogs will compile cleanly on
7737 Linux 2.3 kernels that have renamed i_version to i_generation.
7739 E2fsck now prints a progress/completion bar (and not just a simple
7740 spinner) if the -C0 option is requested or if it receives a SIGUSR1
7741 signal. Fsck will automatically manage the (potentially multiple)
7742 e2fsck processes to print completion bars if it is given a -C option,
7743 with the right thing happening if multiple filesystems are being
7744 checked in parallel.
7746 Mke2fs now has better automatic heuristics to determine the filesystem
7747 parameters to be used for a particular filesystem. Added a new option
7748 -T which allows the user to specify how the filesystem is to be used,
7749 which helps mke2fs do a better job selecting the filesystem parameters.
7751 Mke2fs now creates revision 1 filesystems by default, and with the
7752 sparse superblock feature enabled. The sparse superblock feature is
7753 not understood by Linux 2.0 kernels, so they will only allow read-only
7754 mounts of filesystems with this sparse superblocks.
7756 Fix bug where if /dev/null couldn't be opened (should never happen),
7757 e2fsck would hang in a tight loop.
7759 Make e2fsck handle the case where /lost+found isn't a directory.
7761 E2fsck now uses mallinfo if it exists to get accurate statistics about
7764 Fix bug in e2fsck where it wouldn't check to see if a disconnected
7765 inode had any problems before connecting it to /lost+found.
7767 Add check to e2fsck so it makes sure that total number of inodes in
7768 the filesystem is a sane number.
7770 Fix fencepost error when clearing an the end of the block bitmap which
7771 caused the last block in the bitmap not to get cleared.
7773 Cleaned up a number of messages in e2fsck:
7774 * The message "Group's #'s copy of the group descriptor..."
7775 was fixed so that the correct number would be displayed.
7776 * Added missing space in the "disk write-protected" error message
7777 * Cleaned up the error message printed when a non-interactive
7778 e2fsck needs to abort a check because the filesystem
7779 appears to be mounted.
7781 Added a new command-line utility, uuidgen, which will create and print
7784 Make debugfs's icheck command more robust by checking to make sure an
7785 inode has valid blocks before iterating over the inode's blocks.
7787 UUID generation now uses a random-based scheme whenever possible to
7788 prevent potential privacy problems.
7790 Man pages for all of the UUID functions in the library were added.
7792 Fixed bug in fsck so it won't coredump if a filesystem not in
7793 /etc/fstab is given to it.
7795 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
7796 that most of the other mount utilities understands.
7798 Mke2fs will make a filesystem even if it appears mounted if the force
7801 Dumpe2fs has new command-line options which allow a filesystem expert
7802 to specify the superblock and blocksize when opening a filesystem.
7803 This is mainly useful when examining the remains of a toasted
7806 The badblocks program has been updated to display correctly on disks
7807 with large block numbers.
7809 The badblocks program no longer gives spurious errors when errors
7810 occur on non-block boundaries, which is common if the blocksize is
7813 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
7814 MKE2FS_SYNC environment variable is set. This is to work around a VM
7815 bug in the 2.0 kernel. I've heard a report that a RAID user was able
7816 to trigger it even using a 2.2 kernel, but hopefully it will not be
7817 needed for most Linux 2.2 users.
7819 Fixed miscellaneous documentation and man pages.
7824 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
7825 in e2fsck's pass1.c really should have been static.
7827 The return value of the uuid_compare() function was changed to make it
7828 match with the conventions used by strcmp, memcmp, and Paul Leach's
7829 UUID sample document.
7831 The "make depend" process has now been made more automated; it now
7832 automatically word-wraps the dependencies, and only replaces source
7833 Makefile.in if there has been a change in the dependencies. Also, a
7834 top-level "make depend" now recurses through all the subdirectories
7837 The Makefile in .../util has been changed so that subst is built using
7838 the native C compiler during a cross-compilation, since the subst
7839 program is only used during the build process. Also add an explicit
7840 rule to build util/subst by cd'ing to the correct directory and
7843 The man directories are defined in terms mandir, so that the configure
7844 script can override the location of the manual pages.
7846 The config files have been updated to recognize new machine types for
7847 both the i386 and alpha families.
7849 Fsck has been modified so that it will accurately create an
7850 fsck_instance even when the noexecute flag is set. This allows for
7851 accurate debugging of the fsck pass structure. Also, when the verbose
7852 flag is given twice, fsck will print debugging information about when
7853 fsck is waiting for jobs to finish.
7856 E2fsprogs 1.14 (January 9, 1999)
7857 ================================
7859 Fix the fstab parsing code so that it can handle blank lines and
7860 comment characters. Also, missing pass numbers need to be treated as
7863 Fixed a bug in e2fsck where under some circumstances (when e2fsck
7864 needs to restart processing after fixing an egregious inconsistency)
7865 it would try to access already freed memory.
7867 E2fsck now prints non-printable characters in directory entries and
7868 pathnames using '^' and 'M-' notation.
7870 Fixed chattr so that it will ignore symbolic links when doing
7871 recursive descent traversals. For both chattr and lsattr, no longer
7872 print the version string unless the -V option is given.
7874 Allow the system administrator to directly specify the number of
7875 inodes desired in the filesystem, for some special cases where this is
7878 Fix portability problems so that e2fsprogs can be compiled under Linux
7879 1.2 systems and Solaris systems.
7881 Update the config.guess file with a more recent version that will
7882 identify newer Linux platforms.
7887 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
7888 an inode number of zero is passed to them.
7890 E2fsprogs 1.13 (December 15, 1998)
7891 ==================================
7893 Fixed a bug in debugfs where an error messages weren't getting printed
7894 when the ext2 library routines to read inodes returned errors in the
7895 stat, cmri and rm commands.
7897 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
7898 provided, it won't create an inode table smaller than the minimum
7899 number of inodes required for a proper ext2 filesystem.
7901 Fsck now parses the /etc/fstab file directly (instead of using
7902 getmntent()), so that it can distinguish between a missing pass number
7903 field and pass number field of zero. This caused problems for
7904 diskless workstations where all of the filesystems in /etc/fstab have
7905 an explicit pass number of zero, and fsck could not distinguish this
7906 from a /etc/fstab file with missing pass numbers.
7908 E2fsck will create a /lost+found directory if there isn't one in the
7909 filesystem, since it's safer to create the lost+found directory before
7912 Fixed e2fsck so that it would detect bogus immutable inodes which
7913 happen to be sockets and FIFO files, and offer to clear them.
7915 If a filesystem has multiple reasons why it needs to be checked, and
7916 one of the reasons is that it is uncleanly mounted, e2fsck will print
7917 that as the reason why the filesystem is being checked.
7919 Cleaned up the output routines of mke2fs so that it doesn't overflow
7920 an 80 column display when formatting really big filesystems.
7922 Added a sanity check to e2fsck to make sure that file descriptors 0,
7923 1, 2 are open before opening the hard disk. This avoids a problem
7924 where a broken program might exec e2fsck with those file descriptors
7925 closed, which would cause disastrous results if the kernel returns a
7926 file descriptor for the block device which is also used by FILE *
7929 Fixed up the e2fsck progress reporting functions so that the values
7930 reliably reach 100% at the completion of all of the e2fsck passes.
7932 Fixed minor documentation bugs in man pages and usage messages.
7937 Fixed a number of lint warnings in the ext2fs library and potential
7938 portability problems from other OS's header files that might define
7939 CPP macros for names like "max" and "min".
7941 ext2fs_badblocks_list_add() has been made more efficient when it needs
7942 to grow the bad blocks list.
7944 Fixed a bug in e2fsck which caused it to dereference a freed pointer
7945 just before exiting.
7947 Fixed the substitution process for generating the mk_cmds and compile_et
7948 scripts so that they will work outside of the build tree.
7950 Add sanity check to e2fsck so that if an internal routine
7951 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
7952 and causing a core dump. This should never happen, but...
7954 E2fsprogs 1.12 (July 9, 1998)
7955 ==================================
7957 E2fsprogs now works with glibc (at least with the version shipped with
7958 RedHat 5.0). The ext2fs_llseek() function should now work even with
7959 i386 ELF shared libraries and if llseek() is not present. We also
7960 explicitly do a configure test to see if (a) llseek is in libc, and
7961 (b) if llseek is declared in the system header files. (See standard
7962 complaints about libc developers don't understand the concept of
7963 compatibility with previous versions of libc.)
7965 The ext2fs library now writes out the block group number in each of
7966 the superblock copies. This makes it easier to automatically
7967 determine the starting block group of the filesystem when the block
7968 group information is trashed.
7970 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
7971 which means that e2fsprogs will ignore the high 8 bits of the
7972 directory entry's name_len field, so that it can be used for other
7975 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
7976 E2fsprogs will now support filesystems with 64-bit sized files.
7978 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
7980 Added new program "e2label", contributed by Andries Brouwer. E2label
7981 provides an easy-to-use interface to modify the filesystem label.
7983 Fixed bug so that lsattr -v works instead of producing a core dump.
7985 Fixed a minor bug in mke2fs so that all groups with bad superblock
7986 backup blocks are printed (not just the first one).
7988 Mke2fs will check the size of the device, and if the user specifies a
7989 filesystem size larger than the apparent size of the device it will
7990 print a warning message and ask if the user wants to proceed.
7992 E2fsck has a new option -C, which sends completion information to the
7993 specified file descriptor. For the most part, this is intended for
7994 programs to use, although -C 0 will print a spinning character to the
7995 stdout device, which may be useful for users who want to see something
7996 happening while e2fsck goes about its business.
7998 Fixed a bug in e2fsck which could cause a core dump when it needs to
7999 expand the /lost+found directory, and sometimes the bitmaps haven't
8000 been merged in. Also fixed a related bug where ext2fs_write_dir_block
8001 was used to write out a non-directory block. (Which would be bad on a
8002 non-Intel platform with byte swapping going on.)
8004 Fixed bug in e2fsck where it would print a "programming error" message
8005 instead of correctly identifying where a bad block was in used when
8006 the bad block was in a non-primary superblock or block group
8007 descriptor. Also fixed a related bug when sparse superblocks are in
8008 use and there is a bad block where a superblock or block group
8009 descriptor would have been in a group that doesn't include a
8012 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
8013 the block group descriptor table is corrupt, it was possible to try to
8014 allocate a huge array, fail, and then abort e2fsck.
8015 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
8016 and substitutes reasonable values if the descriptors are obviously bogus.
8018 If e2fsck finds a device file which has the immutable flag set and the
8019 i_blocks beyond the normal device number are non-zero, e2fsck will
8020 offer to remove it, since it's probably caused by garbage in the inode
8023 When opening a filesystem, e2fsck specially checks for the EROFS error
8024 code, and prints a specific error message to the user which is more
8027 If the filesystem revision is too high, change the e2fsck to print
8028 that this is either because e2fsck is out of date, or because the
8029 superblock is corrupt.
8031 E2fsck now checks for directories that have duplicate '.' and '..'
8032 entries, and fixes this corruption.
8034 E2fsck no longer forces a sync of the filesystem (with attendant sleep
8035 calls) at all times. The ext2fs_flush() function now performs a sync
8036 only if it needed to write data blocks to disk.
8038 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
8039 certain errors would not be properly reported.
8041 Updated and expanded a few points in the man pages which users
8042 complained weren't explicit enough.
8044 Added special case byte-swapping code if compiling on the PowerPC, to
8045 accommodate the strange big-endian variant of the ext2 filesystem that
8046 was previously used on the PowerPC port.
8052 Removed C++ keywords from the ext2fs libraries so that it could be
8055 E2fsck's internal organization has now been massively reorganized so
8056 that pass*.c don't have any printf statements. Instead, all problems
8057 are reported through the fix_problem() abstraction interface. E2fsck
8058 has also been revamped so that it can be called as a library from a
8061 Added new fileio primitives in libext2fs for reading and writing
8062 files on an unmounted ext2 filesystem. This interface is now used by
8065 Added a new libext2fs function for mapping logical block numbers of
8066 a file to a physical block number.
8068 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
8069 a block, zeros it, and updates the filesystem accounting records
8072 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
8073 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
8075 The libext2fs functions now use a set of memory allocation wrapper
8076 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
8077 instead of malloc, free, and resize. This makes it easier for us to
8078 be ported to strange environments where malloc, et. al. aren't
8079 necessarily available.
8081 Change the libext2fs function to return ext2-specific error codes
8082 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
8083 and depending on the existence of system error codes (such as EEXIST
8086 Renamed io.h to ext2_io.h to avoid collision with other OS's header
8089 Add protection against ext2_io.h and ext2fs.h being included multiple
8092 The types used for memory lengths, etc. have been made more portable.
8093 In general, the code has been made 16-bit safe. Added Mark
8094 Habersack's contributed DOS disk i/o routines.
8096 Miscellaneous portability fixes, including not depending on char's
8099 The io_channel structure has a new element, app_data, which is
8100 initialized by the ext2fs routines to contain a copy of the filesystem
8103 ext2fs_check_directory()'s callback function may now return the error
8104 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
8105 really do the checking, despite the presence of the callback function.
8108 E2fsprogs 1.11 (June 17, 1997)
8109 ==============================
8111 Fixed e2fsck to detect (previously ignored) conflicts between the
8112 superblock or block group descriptors and block bitmaps, inode
8113 bitmaps, and inode tables.
8115 Fixed bug in e2fsck so that when the message printed out when a block
8116 or inode bitmap conflicts with other data, it has the correct group
8119 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
8120 to badblocks. This meant that not all of the filesystem was being
8121 tested for bad blocks!
8123 Fixed an array boundary overrun case which cropped up in
8124 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
8127 Adjusted the number of columns printed by mke2fs when displaying the
8128 superblock backups to avoid running over 80 columns when making a
8129 really big filesystem.
8131 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
8132 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
8133 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
8138 Fixed install rule in lib/ss so that ss_err.h is actually getting
8141 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
8142 passed back to the caller.
8144 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
8145 setting the current inode number (which meant this function wasn't
8148 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
8149 blocks in the bitmap when increasing the size of the bitmap.
8151 Changed the initial number of blocks allocated by ext2fs_init_dblist()
8152 to be more realistic.
8154 Added a new function ext2fs_allocate_group_table, which sets up the
8155 group descriptor information (and allocates inode and block bitmaps,
8156 and inode tables for a particular group). The function was created by
8157 factoring out code form ext2fs_allocate_tables().
8159 Added a new function ext2fs_move_blocks which takes a bitmap of the
8160 blocks to be moved, and moves them to another location on the
8163 Make the unix_io channel's io_channel_flush implementation calls sync()
8164 to to flush the kernel buffers to disk.
8166 Added a new function ext2fs_dblist_count returns the number of
8167 directory blocks in dblist.
8170 E2fsprogs 1.10 (April 24, 1997)
8171 ===============================
8173 Mke2fs once again defaults to creating revision #0 filesystems, since
8174 people were complaining about breaking compatibility with 1.2 kernels.
8175 Warning messages were added to the mke2fs and tune2fs man pages that
8176 the sparse superblock option isn't supported by most kernels yet (1.2
8177 and 2.0 both don't support parse superblocks.)
8179 Added new flag to mke2fs, -R <raid options>, which allows the user to
8180 tell mke2fs about the RAID configuration of the filesystem. Currently
8181 the only supported raid option is "stride" which specifies the width
8184 Fixed bug in e2fsck where pass1b would bomb out if there were any
8185 blocks marked bad in the inode table.
8187 Fixed rare bug in mke2fs where if the user had a very unlucky number
8188 of blocks in a filesystem (probability less than .002) the resulting
8189 filesystem would be corrupt in the last block group.
8191 Fixed bug where if e2fsck tried to allocate a block to fix a
8192 filesystem corruption problem and the filesystem had no free blocks,
8193 ext2fs_new_block() would loop forever.
8195 The configure script now checks explicitly to see if "-static" works,
8196 since that can't be assumed to be true --- RedHat doesn't install
8197 libc-static by default.
8199 Fixed bug in libext2's block iterator functions where under some
8200 circumstances, file with holes would cause the bcount parameter to the
8201 callback function to be incorrect. This bug didn't affect any of
8202 e2fsprogs programs, but it was discovered by Paul Mackerras, the
8203 author of the PPC boot loader.
8205 Removed use of static variables to store the inode cache in libext2fs.
8206 This caused problems if more than one filesystem was accessed via
8207 libext2fs (static variables in libraries are generally a bad idea).
8208 Again, this didn't affect e2fsprogs programs, but it was discovered by
8211 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
8212 will compile cleanly with 1.2.13 kernels (even with a.out shared
8218 Added new functions to duplicate an ext2 filesystem handle, and its
8219 associated substructure. New functions: ext2fs_dup_handle(),
8220 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
8221 Other structures, such as the io_channel and the inode_cache, now have
8222 a ref count so that they only get freed when they are no longer used
8223 by any filesystem handle. (These functions were added as part of the
8224 development effort for an ext2 resizer).
8226 E2fsprogs 1.09 (April 14, 1997)
8227 ===============================
8229 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
8230 accidentally introduced in the 1.08 release. The overhead calculation
8231 was accidentally removed, which caused ext2fs_initialize() to not
8232 notice when the filesystem size needed to be adjusted down because
8233 there wasn't enough space in the last block group.
8235 Fixed bug in version parsing library routine; it was always parsing
8236 the library version string, instead of using the passed-in string.
8238 Clarified chattr man page.
8240 E2fsprogs 1.08 (April 10, 1997)
8241 ===============================
8243 E2fsck 1.07 was very slow when checking very large filesystems with a
8244 lot of files that had hard links (i.e., news spools). This was fixed
8245 by seriously revamping the icount abstraction. Added a formal test
8246 suite for the icount abstraction.
8248 Debugfs now has a "-l" option to the "ls" command, which lists the
8249 inode number, permissions, owner, group, size, and name of the files
8252 Fix a bug in e2fsck where when a directory had its blocks moved to
8253 another location during the pass 1b processing, the directory block
8254 list wasn't updated, so pass 2 wouldn't check (and correct) the
8255 correct directory block.
8257 E2fsck will now treat inodes which contain blocks which are claimed by
8258 the filesystem metadata by treating them as multiply claimed blocks.
8259 This way, the data in those blocks can be copied to a new block during
8260 the pass 1b--1d processing.
8262 E2fsck will attempt to determine the correct superblock number and
8263 display it in the diagnostic and warning messages if possible.
8265 Add support for a new (incompatible) feature, "sparse_super". This
8266 feature reduces the number of blocks which contain copies of backup
8267 superblocks and block group descriptors. (It is only an incompatible
8268 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
8269 support a new -s option; e2fsck will recognize filesystems built with
8270 this feature turned on.
8272 E2fsck now checks the library to make sure is the correct version,
8273 using new library functions. (This helps to diagnose incorrectly
8274 installed e2fsprogs distributions.)
8276 Dumpe2fs now prints more information; its now prints the the
8277 filesystem revision number, the filesystem sparse_super feature (if
8278 present), the block ranges for each block group, and the offset from
8279 the beginning of the block group.
8281 Mke2fs now distributes the inode and block bitmap blok so that the
8282 won't be concentrated in one or two disks in RAID/striping setups.
8283 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
8284 choose the largest blocks per group that be chosen. (For 2k blocks,
8285 you can have up to 16384 blocks/group; for 4k blocks, you can have up
8286 to 32768 blocks/group.) Previously mke2fs would not allow
8287 specification of more than 8192 blocks per group, even if you were
8288 using a 2k or 4k block group.
8293 Added a new function ext2fs_create_icount2() which takes a "hint"
8294 argument. This hint argument presets the icount array with the list
8295 of inodes which actually need to be in the icount array. This really
8296 helps to speed up e2fsck.
8298 Added a new function ext2fs_icount_validate() which checks the rep
8299 invariant for the icount structure. This is used mostly for testing.
8301 The error message given when a bad inode number is passed to
8302 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
8303 EXT2FS_UNMARK_ERROR).
8305 Added a new function ext2fs_set_dir_block which sets the block of a
8306 dblist entry, given the directory inode and blockcnt.
8308 Added a new function ext2fs_get_library_version() which returns the
8309 current library version, and ext2fs_parse_version_string() which
8310 returns a version number based on a e2fsprogs version string.
8312 The icount functions will return EINVAL if the passed in inode number
8315 E2fsprogs 1.07 (March 9, 1997)
8316 ==============================
8318 E2fsck is now uses much less memory when checking really large
8319 filesystems (or rather, filesystems with a large number of inodes).
8320 Previously a filesystem with 1 million inodes required 4 megabytes of
8321 memory to store inode count statistics; that storage requirement has
8322 now been reduced to roughly half a megabyte.
8324 E2fsck can now properly deal with bad blocks appearing inside the
8325 inode table. Instead of trying to relocate the inode table (which
8326 often failed because there wasn't enough space), the inodes in the bad
8327 block are marked as in use.
8329 E2fsck will automatically try to use the backup superblocks if the
8330 primary superblocks have a bad magic number or have missing meta-data
8331 blocks (or meta-data blocks which are out of range).
8333 E2fsck's pass 3 has been made more efficient; most noticeable on
8334 filesystems with a very large number of directories.
8336 Completely revamped e2fsck's system of printing problem reports. It
8337 is now table driven, to make them more easily customizable and
8338 extendable. Error messages which can be printed out during preen mode
8339 are now one line long.
8341 Fixed e2fsck's filesystem swapping code so that it won't try to swap
8342 fast symbolic links or deleted files.
8344 Fixed e2fsck core dumping when fixing a filesystem which has no
8345 directories (not even a root directory).
8347 Added a check to e2fsck to make sure that the length of every
8348 directory entry is a multiple of 4 (since the kernel complains if it
8351 Added a check to e2fsck to make sure that a directory entry isn't a
8352 link to the root directory, since that isn't allowed.
8354 Added a check to e2fsck to now make sure the '.' and '..' directory
8355 entries are null terminated, since the 2.0 kernel requires it.
8357 Added check to write_bitmaps() to make sure the superblock doesn't get
8358 trashed if the inode or block bitmap is marked as being block zero.
8360 Added checking of the new feature set fields in the superblock, to
8361 avoid dealing with new filesystem features that this package wasn't
8364 Fixed a fencepost error in ext2fs_new_block() which would occasionally
8365 try to allocate a block beyond the end of a filesystem.
8367 When the UUID library picks a random IEEE 802 address (because it
8368 can't find one from a network card), it sets the multicast bit, to
8369 avoid conflicting with a legitimate IEEE 802 address.
8371 Mke2fs now sets the root directory's owner to be the real uid of the
8372 user running mke2fs. If the real uid is non-zero, it also sets
8373 the group ownership of the root directory to be the real group-id of
8374 the user running mke2fs.
8376 Mke2fs now has more intelligent error checking when it is given a
8377 non-existent device.
8379 When badblocks is given the -vv option, it now updates the block that
8380 it is currently testing on every block.
8382 Fixed a bug in fsck where it wouldn't modify the PATH environment
8383 currently correctly if PATH wasn't already set.
8385 Shared libraries now built with dependencies. This allows the shared
8386 library files to be used with dlopen(); it also makes the transition
8387 to libc 6 easier, since ld.so can tell which libc a particular shared
8388 library expects to use.
8393 Added new abstraction (defined in dblist.c) for maintaining a list of
8394 blocks which belongs to directories. This is used in e2fsck and other
8395 programs which need to iterate over all directories.
8397 Added new functions which test to see if a contiguous range of blocks
8398 (or inodes) are available. (ext2fs_*_bitmap_range).
8400 Added new function (ext2_inode_has_valid_blocks) which returns true if
8401 an inode has valid blocks. (moved from e2fsck code).
8403 Added new function (ext2fs_allocate_tables) which allocates the
8404 meta-data blocks as part of initializing a filesystem. (moved from
8407 Added a new I/O manager for testing purposes. It will either allow a
8408 program to intercept I/O requests, or print debugging messages to
8409 trace the activity of a program using the I/O manager.
8411 The badblocks_list functions now store the bad blocks in a sorted
8412 order, and use a binary search to speed up badblocks_list_test.
8414 The inode scan function ext2fs_get_next_inode() may now return a soft
8415 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
8416 those cases where part of an inode table is missing or there is a bad
8417 block in the inode table.
8419 Added a new function (ext2fs_block_iterate2) which adds new arguments to
8420 the callback function to return a pointer (block and offset) to the
8421 reference of the block.
8423 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
8424 application to jump to a particular block group while doing an inode
8427 The badblocks list functions were renamed from badblocks_* to
8428 ext2fs_badblocks_*. Backwards compatibility functions are available
8429 for now, but programs should be modified to use the new interface.
8431 Some of the library functions were reorganized into separate files to
8432 reduce the size of some programs which statically link against the
8435 Put in some miscellaneous fixes for the Alpha platform.
8438 E2fsprogs 1.06 (October 7, 1996)
8439 ================================
8441 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
8442 smash the backup copies in ext2fs_close(). (The problem was that when
8443 e2fsck -p discovered the problem, while it was closing the filesystem
8444 and exiting, it was also blowing away the backup superblocks on the
8445 disk, which was less than friendly.) We now make it the case that we
8446 only write out the backup superblock and the back block descriptors if
8447 the filesystem is completely free from problems.
8449 Fixed a bug in block_interate in the lib/ext2fs library which caused
8450 e2fsck to fail on GNU Hurd-created filesystems.
8452 Add support for Linux/FT's bootloader, which actually uses
8453 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
8456 Add support for the "A" (no atime update) attribute. (Note: this
8457 attribute is not yet in production kernels.)
8459 The test suite is not automatically run when doing a "make all" from
8460 the top level directory. Users should manually run "make check" if
8461 they wish to run the test suite.
8463 Upon a preenhalt(), make the printed message more explicit that
8464 running e2fsck "MANUALLY" means without the -p or -a options.
8466 In e2fsck, if a disconnected inode is zero-length, offer to clear it
8467 instead of offering to connect it to lost+found.
8469 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
8470 e2fsck to be run over it, change e2fsck to explicitly display this
8473 For dumpe2fs and e2fsck, cause the -V option to print out which
8474 version of the ext2fs library is actually getting used. (This will
8475 help detect mismatches of using a 1.06 utility with a 1.05 library,
8481 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
8482 the naming convention.
8484 In ext2fs_initialize(), make sure the description for the inode bitmap
8485 is correctly initialize.
8487 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
8489 E2fsprogs 1.05 (September 7, 1996)
8490 ==================================
8492 Add support for new fields in the ext2 superblock --- volume name,
8493 volume UUID, and last mounted field. Dumpe2fs displays these fields,
8494 tune2fs and mke2fs allows you to set them. E2fsck will automatically
8495 generate a UUID for those volumes that don't have them.
8497 Put in support for e2fsck to recognize HURD specific ext2 features ---
8498 most notably, the translator block. The e2fsprogs tools will now use
8499 the creator_os field in the superblock to correctly handle different
8500 OS-specific variants of the ext2 filesystem.
8502 E2fsck now fixes inodes which have a the deletion time set, but which
8503 have a non-zero i_link_count field by offering to clear the deletion
8504 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
8505 ext2 kernel behavior) and offered to unlink the file.
8507 If e2fsck sets the clean bit, but nothing else, set the exit code
8508 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
8509 set the filesystem valid bit when it was previously cleared. :-) This
8510 was needed to make the HURD fsck driver happy.
8512 If the user refuses to attach an unattached inode, e2fsck will no
8513 longer set the inode's link count. Otherwise, the inode would end up
8514 getting marked as unused, which might cause loss of data later.
8516 Make the message issued by e2fsck when the superblock is corrupt less
8517 confusing for users. It now mentions that another reason for the
8518 "corrupt superblock" message might be that the partition might not be
8519 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
8521 Make the libext2 library more robust so that e2fsck won't coredump on
8522 an illegal superblock where the blocksize is zero. (f_crashdisk is
8525 By default, create filesystems where the default checkinterval is 6
8526 months (180 days). Linux servers can be robust enough that 20 reboots
8527 can be a long, long time.
8529 Added configure flag --enable-old-bitops, which forces the bitops to
8530 use the old (native) bitmask operations. By default on the sparc
8531 platform, the standard ext2 bit ordering is now used.
8533 Added a new feature to e2fsck to byte-swap filesystems; this can be
8534 used to convert old m68k filesystems to use the standard byte-order
8535 storage for the superblock, inodes, and directory blocks. This
8536 function is invoked by using the '-s' option to e2fsck.
8538 Debugfs's "dump" command has been enhanced so that it writes out the
8539 exact size of the file so that the nulls at the end of the file are
8540 eliminated. The command also accept a new "-p" option which will
8541 attempt to preserve the ownership, permissions, and file
8542 modification/access times.
8544 Debugfs has two new options, -f and -R. The -R option allows the user
8545 to execute a single debugfs command from the command line. The -f
8546 option allows the user to specify a "command file" containing debugfs
8547 commands which will get executed.
8549 Dumpe2fs now pretty prints the check interval, instead of just
8550 printing the check interval as a number of seconds.
8552 Fix bugs in debugfs: the params command when no filesystem is opened
8553 no longer causes a core dump. It is now possible to unlink a file
8554 when a pathname containing a '/' is specified.
8556 Tune2fs has a new -C option which sets the number of times the
8557 filesystem has been mounted.
8559 Fix the chattr '-v' option so that it actually works. Chattr was
8560 being buggy about the -v option parsing.
8565 The directory lib/uuid contains a set of library routines to generate
8566 DCE compatible UUIDs.
8568 Extended ext2fs_namei() to handle symbolic links. Added new function
8569 ext2fs_nami_follow() which will follow last symbolic link in the case
8570 where the pathname points to a sym link.
8572 The ext2fs_block_iterate function will now return the HURD translator
8573 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
8574 iterator to return data blocks only. The ext2fs.h file now defines
8575 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
8576 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
8577 count field of the iterator callback function.
8579 The test script driver now takes an optional second argument, which is
8580 the test case to be run. This allows you to run a test case without
8581 needing to run the entire test suite.
8583 On Linux ELF systems, install the .so files in the correct places
8584 (/usr/lib). The .so files must be stored in the same directory as the
8587 Fixed miscellaneous HURD compilation issues with header file being
8588 included in the right order.
8590 Fixed debugfs so that it resets optind to zero, not one, since setting
8591 optind to zero is more correct.
8594 E2fsprogs 1.04 (May 16, 1996)
8595 =============================
8597 First "official" (1.03 was a limited release only) to support building
8598 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
8601 This package includes a RPM specs file, that it can be built using the
8602 RedHat Package Manager.
8604 E2fsck now prints a hint that if there are lots of incorrectly located
8605 inode bitmaps, block bitmaps, and inode table blocks, the user might
8606 want to try using e2fsck -b 8193 first, to see if that fares any
8609 For ext2 filesystem written with the hurd, debugfs will now print out
8610 the translator field when printing an inode structure.
8612 Lots of miscellaneous linking/installation cleanups:
8614 Libraries are now linked using a relative pathname, instead of
8615 relying on -L working correct. It doesn't, in many cases, including
8616 current versions of GNU ld. This guarantees that the build tree is
8617 linking with the right libraries, instead of the ones installed in
8620 Header files, man pages, and the et/ss shell scripts are now
8621 generated using a custom substitution script, instead of relying on
8622 the configure script. This prevents needless recompilation of
8623 files; in addition, the custom substitution script is much faster.
8625 e2fsck may now be linked dynamically, by using the
8626 --enable-dynamic-e2fsck flag to configure. This is not recommended,
8627 since it increases e2fsck's dependence on other files, but some
8628 people need to save disk space, and other critical programs on their
8629 systems were being linked dynamically anyway.
8631 Programs such as fsck which didn't need to be linked against
8632 libext2fs (or mke2fs which didn't need to be linked against libe2p)
8633 only link against libraries they actually need. Otherwise, those
8634 programs would require the presence of libraries that otherwise
8635 could be removed from a rescue diskette.
8637 The ss include files are now installed correctly so they can
8638 actually be used by another package.
8640 If the profiling libraries are built, they are now installed on a
8641 "make install-libs".
8644 E2fsprogs 1.03 (March 27, 1996)
8645 ===============================
8647 Change the m68k bit numbering for bitmasks to match the bit numbering
8648 used by all other ext2 implementations. (This change was requested by
8649 the m68k kernel development team.)
8651 Support (in-development) filesystem format revision which supports
8652 (among other things) dynamically sized inodes.
8654 Fixed a bug in the ext2 library so that an intelligent error is
8655 returned if mke2fs is run with a ridiculously small number of blocks
8658 Fixed a bug in the ext2 library which required that the device be
8659 openable in read/write mode in order to determine its size. This
8660 caused e2fsck -n to require read/write access when it was not
8661 previously necessary.
8663 Fixed a bug in e2fsck which caused it to occasionally fail the test
8664 suite depending on which version of the floating point library it was
8667 Fixed a bug in e2fsck so that it now halts with a fatal error when
8668 certain superblock consistency checks fail. Previously it continued
8669 running e2fsck, with some potential confusing/damaging consequences.
8671 Added new flag to fsck which allows the root to be checked in parallel
8672 with other filesystems. This is not the safest thing in the world to
8673 do, but some system administrators really wanted it.
8675 Fixed -Wall flames in lib/ss.
8678 E2fsprogs 1.02 (January 16, 1996)
8679 =================================
8681 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
8683 Change e2fsck to print statistics of how many non-contiguous files are
8684 on the system. Note that a file which is larger than 8k blocks, it is
8685 guaranteed to be non-contiguous.
8687 In mke2fs, print a warning message if a user tries to format a whole
8688 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
8689 whole disk, the -F (force) option forces mke2fs to format a whole disk
8692 Fix a bug in fsck where in some cases it might start checking
8693 partitions in the next pass before it finishes checking partitions in
8694 the current pass. This still won't cause two partitions on the same
8695 disk will be checked, so it's rarely a problem in real life.
8697 Patch lsattr so that it won't hang when checking a named pipe.
8699 Minor compilation fixes:
8700 * Fix the order of libraries that were linked in debugfs.
8701 * Allow the sources to be compiled with -ansi turned on.
