1 E2fsprogs 1.42 (November 29, 2011)
2 ==================================
4 This release of e2fsprogs has support for file systems > 16TB. Online
5 resize requires kernel support which will hopefully be in Linux
6 version 3.2. Offline support is not yet available for > 16TB file
7 systems, but will be coming.
9 This release of e2fsprogs has support for clustered allocation. This
10 reduces the number of block (now cluster) bitmaps by allocating and
11 deallocating space in contiguous power-of-2 collections of blocks,
12 which are called clustered. This is a file system level feature,
13 called 'bigalloc', which must be enabled when the file system is
14 initially formatted. It is not backwards compatible with older
17 Added support for the Multi-Mount Protection (MMP) feature.
19 E2fsck more efficiently uses scratch files for really big file
20 systems. (This is a feature that has to be turned on explicitly; see
21 [scratch_files] in the e2fsck.conf man page.)
23 Fix a bug in e2fsck where if the free blocks and inodes counts are
24 incorrect, e2fsck would fix them without printing an error message.
25 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
26 any explanation of what was fixed.
28 E2fsck will no longer attempt to clone an extended attribute block in
29 pass1b handling if the file system does not support extended
32 E2fsck will be more careful accidentally asking the user to continue
33 if the file system is mounted, so that an escape sequence won't cause
34 a false positive. (Addresses Debian Bug: #619859)
36 E2fsck now uses less cpu time in pass 5 when large portions of the
37 bitmaps are uninitialized.
39 E2fsck will no longer segault when a corrupted file system has a bad
40 extent, and removing it leads to a block needing to be deallocated.
41 (Addresses SourceForge Bug: #2971800)
43 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
44 and print debugging information to make it easier to find potential
47 E2fsck will check to see if the bad block inode looks insane, and will
48 skip trying to use if it certain fields which should be zero look
49 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
50 to get confused and do more harm than good.
52 If e2fsck modifies certain superblock fields which the kernel doesn't
53 look at, it will now mark the superblock as dirty without marking the
54 file system as changed. This avoids signalling the init scripts that
55 a reboot is necessary, since the kernel isn't going to look at those
56 fields, so it won't care if they have been changed.
58 Fixed a bug in the libext2fs library (in the binary search routine of
59 the icount abstraction) that could (very, very rarely) cause e2fsck to
60 die in the middle of pass 1 or pass 2 processing.
62 E2fsck will not try to do a discard operation if the -n option was
63 specified on the command line.
65 E2fsck now supports an extended "discard" option which will cause
66 e2fsck to attempt discard all unused blocks after a full, successful
69 E2fsck will check for the bad block inode to make sure it looks sane
70 before trusting it, to avoid causing more harm than good to the file
73 E2fsck now returns additional status bits in its exit code if it
74 aborts early in the e2fsck run.
76 E2fsck now correctly calculates the maximum file size in the case of
77 the huge_file file system feature enabled without extents.
79 The mke2fs and e2fsck programs now tries to use the punch hole command
80 as a "discard" when operating on normal files.
82 The e2image program now supports the qcow2 format, which is a more
83 efficient way of capturing file system dumps.
85 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
86 per-device defaults to be specified in the configuration file.
88 Mke2fs now supports the reserved_ratio relation in the [defaults] and
89 [fs_types] section in mke2fs.conf.
91 Mke2fs now creates extent-mapped directories for the root and
92 lost+found directories.
94 Mke2fs will skip zero'ing the journal if the extended option
95 "lazy_journal_init" is specified. This can save a lot of time, but it
96 does add a small amount of risk if the system crashes before the
97 journal is overwritten entirely once. It is epsecially useful for
100 Mke2fs will now create file systems that enable user namespace
101 extended attributes and with time- and mount count-based file
102 system checks disabled.
104 Mke2fs will not set a stride or strip size of one block based on block
105 device attributes obtained from sysfs.
107 Mke2fs now displays a progress report during the discard process.
109 Mke2fs now handles extreme file system parameters correctly which
110 previously caused the inodes per group to drop below 8, leading to a
111 segfault. (The inodes per group must be a multiple of 8, but the code
112 didn't correctly deal with an inodes per group count less than 8.)
114 Mke2fs and tune2fs previously would give an error if the user tried
115 setting the stride and stripe-width parameters to zero; but this is
116 necessary to disable the stride and stripe-width settings. So allow
117 setting these superblock fields to zero. (Addresses Google Bug:
120 Mke2fs now gives a warning if the auto-detected block size exceeds the
123 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
124 is the default), mke2fs will now set the s_max_mnt_count superblock
125 field to -1, instead of 0. Kernels older then 3.0 will print a
126 spurious message on each mount then they see a s_max_mnt_count set to
127 0, which will annoy users. (Addresses Debian Bug: #632637)
129 The default mke2fs.conf now has entries for "big" and "huge", which
130 are needed for very big file systems.
132 The resize2fs program now has support for a new online resize ioctl
133 that can support file systems > 16TB, once it arrives in v3.x kernels.
135 Fixed bug which caused resize2fs to fail when shrinking an empty file
136 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
138 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
140 Allow tune2fs to remove external journals if the device can not be
143 Debugfs's icheck will now correctly find inodes which use the
144 searched-for block as an extended attribute block.
146 Debugfs now has a new "punch" command which remove blocks from the
149 Debugfs now has a new "e2freefrag" command which analyzes the free
150 space fragmentation of the file system, using the same code as the
153 Debugfs now has a "filefrag" command which displays information about
154 a file's fragmentation.
156 Add support to build a metadata-only, read-only, stripped-down version
157 of debugfs called rdebugfs.
159 Fixed a potential stack overrun bug in debugfs.
161 The badblocks program now correctly recovers from I/O errors when
162 direct I/O is being used. The badblocks command now also supports a
163 -B option which forces the use of buffered I/O, and the -v option will
164 provide a more detailed breakdown of read, write, and failed
167 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
169 Added support for journals larger than 2GB.
171 Support using both hard links and symlinks when installing e2fsprogs.
173 Add overflow checking to tune2fs -i's fsck interval, which must fit in
176 The debugfs command now has a new 'blocks' command which prints out
177 data blocks of a particular inode in a format which is useful for
180 Filefrag will report 0 extents correctly in verbose mode. (Addresses
181 RedHat Bugzilla: #653234)
183 Filefrag has been fixed so its -v report prints the correct expected
184 block number (previously there had been an off-by-one error). In
185 addition, it will now display the number of contiguous extents when -v
186 is not specified. This makes it consistent with the number of extents
187 printed when the -v option was specified. In addition, the number of
188 contiguous extents is far more interesting/useful than the number of
189 physical extents for very large files. (Addresses Debian Bug:
192 Logsave's usage message has been fixed. (Addresses Debian Bug:
195 Avoid an infinite loop in ext2fs_find_block_device() if there are
196 symlink loops in /dev caused by a buggy udev.
198 Added a useful "fallocate" program to the contrib directory.
200 Fixed an ABI compatibility problem in libext2fs which broke the dump
201 program. Also added back some macros which dump needed so it could
202 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
205 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
208 Added internationalization support for libcom_err error table strings.
210 Fixed various spelling mistakes found in various output strings found
213 Update translations: French, Chinese, Germany, Indonesian, Swedish,
214 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
217 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
218 #614662, #632169, #641838, #627535, #629355)
220 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
226 Initial support for quota as an integrated feature, where the quota
227 files are hidden system files that are automatically maintained by
228 e2fsck is present, although disabled by default. It must be enabled
229 by using the configure option --enable-quota.
231 Reserved the on-disk fields for the metadata checksum and snapshot
232 features, which are currently in development.
234 The ext2fs library now has the new functions ext2fs_punch(),
235 ext2fs_get_memzero() and ext2fs_file_get_inode().
237 The ext2fs library now has support for calculating the crc32c checksum
238 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
240 The I/O manager now supports the discard operation.
242 Reserved file system code points for new 1st class quota feature.
244 Shortened the compilation lines by moving the autoconf defines to
245 a config.h header file.
247 Fixed a potential free of an unitialized pointer in
248 ext2fs_update_bb_inode().
250 Fixed miscellaneous gcc -Wall and coverity warnings.
252 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
254 Fixed a build failure when OMIT_COM_ERR is defined.
256 Improved error checking and fixed memory leaks caused by error return
259 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
260 the fsync() to be skipped.
262 Added a test for extent-mapped journals by mke2fs and tune2fs.
264 Added a test for creating a large (over 4GB) journal using mke2fs.
266 Added a test to make sure the inode size remains constant.
268 The regression test script now prints the list of which tests failed.
270 The regression test system now uses /tmp for its scratch files, which
271 is often a tmpfs mounted file system and hence much faster.
273 The i_e2image test was fixed so it works with valgrind.
275 Tests that rely on debugfs are now skipped if debugfs wasn't built.
277 Fixed the dependencies for "make check" so all required dependencies
278 are built before running the gression tests.
280 A link to com_err.h is installed in $(includedir) during a "make install".
282 The po/*.gmo files are automatically rebuilt if they are missing or
283 out of date. This helps out Debian packaging.
285 Allow ext2fs_get_memalign() to compile on systems that don't have
288 Fixed a namespace leak in libext2fs (tdb_null).
291 E2fsprogs 1.41.14 (December 22, 2010)
292 =====================================
294 Fix spurious complaint in mke2fs where it would complain if the file
295 system type "default" is not defined in mke2fs.conf.
297 The resize2fs program will no longer clear the resize_inode feature
298 when the number reserved group descriptor blocks reaches zero. This
299 allows for subsequent shrinks of the file system to work cleanly for
300 flex_bg file systems.
302 The resize2fs program now handles devices which are exactly 16T;
303 previously it would give an error saying that the file system was too
306 E2fsck (and the libext2fs library) will not use the extended rec_len
307 encoding for file systems whose block size is less than 64k, for
308 consistency with the kernel.
313 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
314 been fixed. (Addresses Sourceforge Bug: #3138115)
316 The ext2fs_block_iterator2() function passed an incorrect ref_offset
317 to its callback function in the case of sparse files. (Addresses
318 Sourceforge Bug: #3081087)
320 Fix some type-punning warnings generated by newer versions of gcc.
323 E2fsprogs 1.41.13 (December 13, 2010)
324 =====================================
326 E2fsck now supports the extended option "-E journal_only", which
327 causes it to only do a journal replay. This is useful for scripts
328 that want to first replay the journal and then check to see if it
331 E2fsck will now support UUID= and LABEL= specifiers for the -j option
332 (which specifies where to find the external journal). (Addresses
335 E2fsck now has support for the problems/<problem code>/force_no
336 configuration option in e2fsck.conf, which forces a problem to not be
339 Dumpe2fs will now avoid printing large negative offsets for the bitmap
340 blocks and instead print a message which is a bit more helpful for
341 flex_bg file systems.
343 Mke2fs will now check the file system type (specified with the -t
344 option) to make sure it is defined in the mke2fs.conf file; if it is
345 not, it will print an error and abort. If the usage type (specified
346 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
347 warning but will continue. (Addresses Debian Bug #594609)
349 Clarified error message from resize2fs clarifying that on-line
350 shrinking is not supported at all. (Addresses Debian Bug #599786)
352 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
353 displayed. (Addresses Debian Bug #555456)
355 E2fsck will open the external journal in exclusive mode, to prevent
356 the journal from getting truncated while it is in use due to a user
357 accidentally trying to run e2fsck on a snapshotted file system volume.
358 (Addresses Debian Bug #587531)
360 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
363 The tune2fs program can now set the uninit_bg feature without
366 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
367 default mount options settings which were added in 2.6.35.
369 The e2fsck and dumpe2fs programs now support the new ext4 superblock
370 fields which track where and when the first and most recent file
371 system errors occurred. These fields are displayed by dumpe2fs and
372 cleared by e2fsck. These new superblock fields were added in 2.6.36.
374 Debugfs now uses a more concicse format for listing extents in its
375 stat command. This format also includes the interior extent tree
376 blocks, which previously was missing from stat's output for
379 Debugfs has a new option, -D, which will request Direct I/O access of
382 Mke2fs will skip initializing the inode table if a device supports
383 discard and the discard operation will result in zero'ed blocks.
385 Badblocks will now correctly backspace over UTF-8 characters when
386 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
387 Debian Bugs #583782 and #587834)
389 E2freefrag will now display the total number of free extents.
391 Resize2fs -P no longer requires a freshly checked filesystem before
392 printing the minimum resize size.
394 Fixed a floating point precision error in a binary tree search routine
395 that can lead to seg fault in e2fsck and resize2fs.
397 Fixed a bug in e2fsck where if both the original and backup superblock
398 are invalid in some way, e2fsck will fail going back to the original
399 superblock because it didn't close the backup superblock first, and
400 the exclusive open prevented the file system from being reopened.
402 Fixed a big in e2freefrag which caused getopt parsing to fail on
403 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
405 Clarified an mke2fs error message so a missed common in an -E option
406 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
407 results in a more understandable explanation to the user.
409 Mke2fs now displays the correct valid inode ratio range when
410 complaining about an invalid inode ratio specified by the user.
412 Mke2fs now understands the extended option "discard" and "nodiscard",
413 and the older option -K is deprecated. The default of whether
414 discards are enabled by default can be controled by the mke2fs.conf
417 Mke2fs's handling of logical and physical sector sizes has been
418 improved to reflect the fact that there will be some SSD's with 8k and
419 16k physical sectors arriving soon. Mke2fs will no longer force block
420 size to be the physical sector size, since there will be devices where
421 the physical sector size is larger than the system's page size, and
422 hence larger than the maximal supported block size. In addition, if
423 the minimal and optimal io size are not exported by the device, and
424 the physical sector size is larger than the block size, the physical
425 sector size will be used to set the Raid I/O optimization hints in the
428 E2fsck will now display a better, more specific error message when the
429 user enters a typo'ed device name, instead of blathering on about
430 alternate superblocks.
432 Fixed various Debian Packaging Issues
434 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
435 #589345, #591083; Addresses Launchpad Bug: #505719)
437 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
438 Polish, Swedish, and Vietnamese translations.
444 Fix a dependency definition for the static and profiled blkid
445 libraries which could cause compile failures in some configurations.
446 (Addresses Debian Bug: #604629)
448 Add support for Direct I/O in the Unix I/O access layer.
450 Fixed a memory leak in the Unix I/O layer when changing block sizes.
452 Fixed minor memory leaks in mke2fs.
454 Added a new function to the ext2fs library, ext2fs_get_memalign().
456 The tst_super_size test program will check to make sure the superblock
457 fields are correctly aligned and will print them out so they can be
458 manually checked for correctness.
460 Fixed some makefile dependencies for test programs in lib/ext2fs.
462 Reserved the feature flags and superblock fields needed for the Next3
465 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
466 EXT4_INCOMPAT_EA_INODE.
469 E2fsprogs 1.41.12 (May 17, 2010)
470 ================================
472 Mke2fs now gives a correct error message if the external journal
473 device is not found. (Addresses Red Hat Bug #572935)
475 Resize2fs -P will now refuse to print a minimum size if the file
476 system is not clean. Previously it would go ahead and print a minimum
477 size anyway, which might not be correct, leading to user confusion.
479 E2fsck now tests for extents that begin at physical block 0 and
480 rejects them as invalid. (Addresses Google Bug: #2573806)
482 Fixed a bug in e2fsck which could cause it to crash when trying to
483 remove an invalid extent and the block bitmaps hadn't yet been loaded.
484 (Addresses SourceForge Bug: #2971800)
486 E2fsck now will completely skip time-based checks if the system clock
487 looks insane or the option broken_system_clock is set in
490 E2fsck would previously report an i_blocks corruption for a 4T file
491 created using posix_fallocate; this bug has been fixed.
493 E2fsck will now correctly mark a sparse journal as invalid and will
494 delete and recreate the journal to address the problem.
496 E2fsck would previously incorrectly ask the user whether she would
497 like to abort the file system check after finding a problem --- and
498 then abort regardless of the user's answer. This is annoying, and
501 E2fsck can now continue even if it fails to recreate the resize
502 inode; previously it would just abort the file system check
505 E2fsck could potentially remove directory entries for inodes found in
506 the unused region of the inode table; this would generally happen on
507 ext4 file systems that do not use journaling. This bug has been fixed
508 by not clearing these directory entries once it has been established
509 that bg_unused_inodes may not be trustworthy; once pass #2 has been
510 completed, e2fsck will restart the file system check from the
511 beginning, and then it will be safe to delete any directory entries
512 pointing to inodes that appear to be deleted. (Addresses Google Bug:
515 E2fsck will not try to set the block group checksums if the user
516 cancels the fsck with a control-C. It's a bad idea to set the
517 checksums if e2fsck hasn't been completed, and it often results an the
518 error message, "Inode bitmap not loaded while setting block group
519 checksum info". (Addresses Launchpad Bug: #582035)
521 The mke2fs program now queries the kernel for the physical as well as
522 the logical sector size, and will not allow a blocksize below the
523 logical, and will strongly encourage a blocksize at least as big as
524 the physical blocksize. This is needed for 4k sector drives that
525 emulate 512 byte sector sizes.
527 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
528 rarely needed, but it is a legal value.
530 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
531 not needed, and offer to clear it; this is a sign of a kernel bug, but
532 more importantly, some released kernels may crash when this situation
533 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
535 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
536 i_size is correct. (Kernels starting with 2.6.34 will set
539 The com_err library will now only output ^M (a CR character) when the
542 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
543 and Vietnamese translations.
545 Fixed various Debian packaging issues --- see debian/changelog for
546 details. (Addresses Debian Bugs: #571247, #563487)
552 The regression test suite now uses its own mke2fs.conf file, so that
553 downstream distributions want change the mke2fs.conf file which is
554 distributed in the RPM or dpkg file, without worrying about screwing
555 up the regression test results.
557 Always build namei.o so that building with configure --disable-debugfs
558 works correctly. Long-term, if we care about reduced e2fsprogs
559 builds, we need a more general solution for deciding what .o files are
560 needed for a particular build. Given that install floppies are going
561 (gone?) the way the dodo bird, we probably don't care, though.
562 (Addresses Sourceforge Bug: #2911433)
564 Add configure options --enable-symlink-build and
565 --enable-symlink-install, which allow e2fsprogs be built using
566 symlinks instad of hard links, and to be installed using symlinks
567 instead of hard links, respectively. It is useful when the file
568 system where the build is taking place, or the file system where
569 e2fsprogs is installed, can't handle hard links for some reason.

572 Fixed compile warning in mke2fs.c.
575 E2fsprogs 1.41.11 (March 14, 2010)
576 ==================================
578 E2fsck will no longer give a fatal error and abort if the physical
579 device has been resized beyond 2**32 blocks. (Addresses Launchpad
582 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
583 the allocation status of the block <blk>. (Addresses Debian Bug:
586 E2fsck now prints a much more emphatic and hopefully scary message
587 when a file system is detected as mounted while doing a read/write
588 check of the filesystem. Hopefully this will dissuade users from
589 thinking, "surely that message doesn't apply to *me*" :-(
591 E2fsck -n will now always open the file system read-only. We now
592 disallow certain combination of options which previously were manual
593 exceptions; this is bad because it causes users to think they are
594 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
595 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
597 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
598 it detected a badly aligned partition. Unfortunately, this broke some
599 distribution installation scripts, so it now just prints the warning
600 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
601 Launchpad Bug: #530071)
603 Mke2fs would take a long time to create very large journal files for
604 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
607 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
608 2.6.34 kernels to make e2fsck not complain about blocks deliberately
609 fallocated() beyond an inode's i_size.
611 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
612 e2fsck -fD can corrupt non-indexed directories when are exists one or
613 more file names which alphabetically sort before ".". This can happen
614 with ext2 filesystems or for small directories (take less than a lock)
615 which contain filenames that begin with a space or some other
616 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad

638 Fix e2fsck's check for extent-mapped directory with an incorrect file
641 Add new e2fsck.conf configuration option, default/broken_system_clock
642 to support systems with broken CMOS hardware clocks. Also, since too
643 many distributions seem to have broken virtualization scripts now,
644 e2fsck will by default accept dates which are off by up to 24 hours by
645 default. (Addresses Debian Bugs: #559776, #557636)

652 of fixing file system problems. This reduces the number of spurious
653 differences found in pass #5.

709 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)

766 E2fsprogs 1.41.9 (August 22, 2009)
767 ==================================
769 Fix a bug in e2fsck routines for reallocating an inode table which
770 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
771 filesystem feature with a relatively rare (and specific) filesystem
772 corruption. This fix causes e2fsck to try to find space for a new
773 portion of the inode table in the containing flex_bg, and if that
774 fails, the new portion of the inode table will be allocated in any
775 free space available in the filesystem.
777 Make e2fsck less annoying by only asking for permission to relocate a
778 block group's inode table once, instead of for every overlapping
779 block. Similarly, only ask once to recompute the block group
780 checksums, instead of once for each corrupted block group's checksum.
782 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
783 not present, and it needs to fall back to using the FIBMAP ioctl.
785 Fix filefrag to correctly print the number of extents for zero-length
786 files. (Addresses Debian Bug: #540376)
788 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
789 to more easily debug the FIBMAP code.
791 Fixed filefrag for non-extent based files.
793 Add a new program, e2freefrag, which displays information about the
794 free space fragmentation in an ext2/3/4 filesystem.
796 Fix inode resizing via tune2fs -I so that it works correctly in the
797 face of non-empty bad blocks inodes, and if the filesystem was
798 formatted using the "mke2fs -E stride=N" option for RAID arrays.
800 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
801 and corrupt large directories if the directory needs to shrink by more
802 than one block. (Addresses Debian Bug: #537510)
804 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
805 last mount times are in the future, they are corrected even if
806 buggy_init_scripts is set. This is needed because otherwise resize2fs
807 will refuse to resize the filesystem, even after running "e2fsck -f".
808 (Addresses Launchpad bug: #373409)
810 E2fsck will now print much fuller information when the last mount time
811 or last written time is in the future, since most people can't seem to
812 believe their distribution has buggy init scripts, or they have a
813 failed CMOS/RTS clock battery.

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

860 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
861 will be careful not to close the file descriptor for its unix domain
862 socket when it detaches itself from the controlling tty. Also add
863 safety checks so that if the unix domain socket between the uuid
864 library and uuidd program is closed for any reason, both the library

907 uninitalized data into the portion of the inode beyond the first 128
908 bytes when operating on inodes mapped via extents; potentially
909 corrupting filesystems.

912 which can cause e2fsck to run out of memory when checking very large
913 filesystems using extents.
915 The logsave program will now filter out the ^A and ^B characters when
916 writing to the console.
918 Harden ext2fs_validate_entry() so that lsdel will not read beyond the

931 filesystems as the kernel when encoding rec_len >= 64k. For 64k
932 filesystems (currently all that is supported by e2fsprogs, this is
933 only a minor corner case).
935 Resize2fs will now update the journal backup fileds in the sup0erblock
936 if the journal is moved; this avoids an unnecessary full fsck after
937 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
939 Fix libext2fs to properly initialize i_extra_size when creating the
940 journal and resize inodes.

962 E2fsprogs 1.41.6 (May 30, 2009)
963 ===============================
965 Fix a critical regression in e2fsck introduced version 1.41.5 which
966 can undo updates to the block group descriptors after a journal replay.
968 If e2fsck receives an I/O error while replaying the journal, prompt
969 the user whether they want to ignore the error or not; if e2fsck is
970 run in preen mode, force fsck to abort the preen pass.
972 Fix a bug which would cause e2fsck to core dump if the filesystem
973 contains a corrupt extent header, and the user declines to clear the
974 inode. (Addresses Sourceforge Bug: #2791794)
976 Fix e2fsck to restart only once in the case of multiple block groups
977 which inodes in use that are in the uninitialized part of the block
980 To reduce user confusion, if the /etc/mtab file is missing
981 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
982 new, explicit error code to indicate this case. This will cause
983 e2fsck to give a clearer error message when the user is using buggy
984 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
987 Fix e2fsck so that if the primary group descriptors are corrupted, but
988 the backup superblock is entirely invalid, to go back to using (and
989 fixing) the priary group descriptors instead of completely giving up
990 on the filesystem. (Addresses Debian Bug: #516820)
992 Change e2fsck to not abort a preen pass if an inode is found to have
993 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
994 kernels (post 2.6.29) will ignore this field. So let's fix it
995 automatically during the preen pass instead of forcing the user to fix
996 this up manually. (Addresses Debian Bug: #526524)
998 Add resource tracking for e2fsck passes 1b through 1d.
1000 Speed up e2fsck by eliminating unnecessary journal checks if the
1001 filesystem is already mounted and doesn't need recovery (since the
1002 kernel would have run the journal when the filesystem was mounted.)
1003 Also speed up e2fsck by avoiding unnecessary block group descriptor
1004 updates in ext2fs_close().
1006 Add support to chattr to migrate inodes from using direct/indirect
1009 Avoid corrupting the filesystem if there is an attempt to shrink a
1010 filesystem using resize2fs smaller than posible by making
1011 ext2fs_set_bmap() more careful not to delete the old block until the
1012 new block can be inserted. In addition, fix a bug in how the minimum
1013 size of the filesystem (plus a safety margin) is calculated, and
1014 modify resize2fs to refuse to shrink the filesystem below that minimum
1015 size without the force flag.
1017 Teach blkid to try to figure out DM device names using take advantage
1018 of information in sysfs when running on kernels (2.6.29 and later)
1019 which provide this information in /sys/block/dm-<N>/dm/name; this is
1020 much faster than scanning for the devncie number in /dev/mapper.
1022 Fix blkid to prefer /dev/mapper/<name> device names instad of the
1023 private /dev/dm-X names.
1025 Add an -a option to debugfs's close_filesys command which writes any
1026 changes to the superblock or block group descriptors to all of the
1027 backup superblock locations.
1029 Add support to the filefrag program to use the FIEMAP ioctl.
1031 Update Chinese translation from the Translation Project.

1034 Launchpad Bug: #381854)
1036 Fixed various Debian packaging issues --- see debian/changelog for
1037 details. (Addresses Debian Bug #506064)
1043 Add test code to make sure e2fsck's problem.c doesn't have two problem
1044 codes assigned to duplicate values.
1046 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1047 (Addresses Sourceforge Bug: #2780205)
1049 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1050 function declaration for init_resource_track() and
1051 print_resource_track() when RESOURCE_TRACK is not defined.
1053 The test code which is used to build the tst_csum progam has been
1054 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1055 avoid compile problems caused by not having a prototype for
1056 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
1058 Update the config.guess and config.sub file to the latest from the
1059 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
1060 Debian Bug: #528330)
1062 Add a new function, ext2fs_extent_open2(), which behaves like
1063 pext2fs_extent_open(), but uses the user-supplied inode structure
1064 when opening an extent instead of reading the inode from disk.
1067 E2fsprogs 1.41.5 (April 23, 2009)
1068 =================================
1070 Fix a number of filesystem corruption bugs in resize2fs when growing
1071 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1074 Debugfs can now set i_file_acl_high via the set_inodes_field command,
1075 and print a 64-bit file acl. This is useful for debugging filesystem
1076 corruptions where the high bits of i_file_acl_high are set. E2fsck
1077 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1078 since some Linux kernel versions pay attention to this field even when
1081 Speed up e2fsck when checking clean filesystems by avoiding
1082 unnecessary block reads, and coalescing the block group descriptor
1083 blocks so they are read using a single read operation.
1085 The libuuid library will now close all file descriptors before running
1086 uuidd. This avoids problems when the calling program has open sockets
1087 which then never get closed because uuidd is a long-running helper
1088 daeomn. (Addresses Launchpad bug: #305057)
1090 In order to avoid unnecessary full filesystem checks by e2fsck after
1091 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1092 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
1094 Mke2fs will avoid trying to create the journal when run in
1095 superblock-only mode (mke2fs -S), since the left-over journal in the
1096 inode table will cause mke2fs to fail.
1098 Fix a bug in libext2fs functions that check to see if a particular
1099 device or filesystem image is mounted, which would cause these
1100 functions to report that a file identical to the (relative) pathname
1101 used by a pseudo-filesystem was mounted when in fact it was not.
1103 Update Czech translation from the Translation Project.
1105 Add Chinese (simplified) translation from the Translation Project.
1107 Fix support for external journals (which was broken in e2fsprogs
1110 Fix a regression in debugfs where the "stat" command when no
1111 filesystem was open would cause debugfs to crash with a segmentation
1114 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1115 used to support filesystems without a journal. Update the blkid
1116 library so it understands this.
1118 The blkid library will remove an entry from the blkid cache
1119 representing the entire disk if partitions are found, since presuambly
1120 the device previously had no partition table, but has now transitioned
1121 to using a partition table.
1123 Add a check to mke2fs and tune2fs that the argument to the -m option
1124 (which specifies the reserved ratio) must be greater than zero.
1125 (Addresses Debian Bug: #517015)
1127 Add support for tracking the number kilobytes written to the
1128 filesystem via the superblock field s_kbytes_written. It will be
1129 updated by the kernel as well as by e2fsprogs programs which write to
1130 the filesystem. This is useful for tracking the wear to filesystems
1131 on Solid Sstate Drives.

1153 system-installed blkid implementation via the configure option
1157 E2fsprogs 1.41.4 (January 27, 2009)
1158 ===================================
1160 Fixed a bug which could sometimes cause blkid to return an exit value
1161 of zero for a non-existent device (Addresses Debian Bug: #502541)
1163 Blkid will now recognize ext3 filesystems that have the test_fs flag
1164 set as ext3 filesystems.
1166 The blkid library will now recognize btrfs filesystems and swap
1167 devices currently used by user-level software suspend.
1169 Tune2fs now updates the block group checksums when changing the UUID
1170 to avoid causing e2fsck to complain vociferously at the next reboot.
1172 Tune2fs's inode size resizing algorithms have been fixed so it is not
1173 vastly inefficient for moderate-to-large filesystems, due to some
1174 O(n**2) and O(n*m) algorithms that didn't scale well at all.
1176 Fix tune2fs's inode resizing algorithm so it will not corrupt
1177 filesystems laid out for RAID filesystems; in addition, tune2fs will
1178 refuse to change the inode size for filesystems that have the flex_bg
1179 feature enabled. (This is a limitation in the current implementation
1182 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1183 filesystems with 32-bit block numbers, when the headers for 64-bit
1184 block numbers was added. This regression has been fixed.
1186 Debugfs's ncheck command has been fixed to avoid printing garbage
1187 characters at the end of file names.
1189 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
1190 when shrinking filesystems with uninit_bg feature would not be moved.
1191 In addition, blocks and inode table blocks were not being correctly
1192 freed when shrinking filesystems with the flex_bg feable, which caused
1193 resize2fs -M to fail. Finally, when blocks are moved, make sure the
1194 uninitialized flag in extents is preserved.
1196 Fix bug which caused dumpe2fs to abort with an error if run on a
1197 filesystem that contained an external journal.
1199 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1200 for this in argv[0] to provide better legacy support for these
1201 distributions. This is a practice that should NOT be continued,
1204 Mke2fs now has a new option -U, which allows the user to specify the
1205 UUID that should be used for the new filesystem.
1207 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1208 minus one block. This allows users who have read that ext3 supports
1209 up to 16TB filesystems and who create a 16TB LVM to not get confused,
1210 since the true limit is really 16TB minus one block.
1212 E2fsck will no longer abort an fsck run if block group has an errant
1215 E2fsck now distinguishes between fragmented directories and fragmented
1216 files in verbose mode statistics and in the fragcheck report.
1218 Fix a bug in e2fsck which casued it double count non-contiguous
1219 extent-based inodes.
1221 E2fsck will leave some slack space when repacking directories to allow
1222 room for a few directory entries to be added without causing leaf
1223 nodes to be split right away.
1225 Fix a bug which caused e2fsck to crash when it comes across a
1226 corrupted interior node in an extent tree with the error message:
1227 "Error1: Corrupt extent header on inode XXXXXX"
1229 E2fsck problem descriptions involving the journal are no longer
1230 referred to as "ext3" problems, since ext4 filesystems also have
1233 Fix a long-standing bug in e2fsck which would cause it to crash when
1234 replying journals for filesystems with block sizes greater than 8k.
1236 Update Catalan translation from the Translation Project.
1238 Fixed various Debian packaging issues --- see debian/changelog for
1239 details. (Addresses Debian Bugs: #503057, #502323, #511207)
1244 Fix build of e2fsck.profiled, and add support for building profiled
1245 binaries in the misc directory if configured with --enable-profile.
1247 The ext2fs_open() function now performs more sanity checks on the
1248 superblock to avoid potential divide by zero errors by other parts of
1251 The ext2fs_read_inode_full() function now has a safety check to avoid
1252 a segmentation fault on corrupted filesystems.
1254 The ext2fs_new_inode() function now has a sanity check so that if the
1255 s_first_inode field in the superblock is insane, it will return
1256 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1258 To avoid segmentation faults, ext2fs_block_alloc_stats() and
1259 ext2fs_inode_alloc_stats() now validates the passed inode or block
1260 number to avoid overrunning an array boundary.
1262 Various signed/unsigned errors for variables containing block numbers
1265 Accomodations for gcc's stupidity in not realizing that constant
1266 strings that do not contain a '%' character are safe to use in format
1267 strings have been made so that distributions that want to compile
1268 e2fsprogs with -Werror=format-security have an easier time doing so.
1270 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1272 Added the utility make-sparse.c to the contrib directory.
1274 The ext2fs_block_iterate2() function now reflects errors from
1275 ext2fs_extent_set_bmap() to the caller, if the callback tries to
1276 change a block on an extent-based file, and ext2fs_extent_set_bmap()
1277 fails for some reason (for example, there isn't enough disk space to
1278 split a node and expand the extent tree.
1280 The ext2fs_block_iterate2() function will preserve the uninit flag in
1281 extents when the callback function modifies a block in an extent-based
1284 E2fsck will now flag filesystems that have an insane s_first_ino field
1285 in their superblock, and attempt to use a backup superblock to repair
1289 E2fsprogs 1.41.3 (October 12, 2008)
1290 ===================================
1292 E2fsck has been fixed so it prints the correct inode number for
1293 uinit_bg related problems.
1295 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1296 is available on linux. This can be disabled via a configuration
1297 option in /etc/e2fsck.conf.
1299 Fix a file descriptor leak in libblkid when checking to see if an ext4
1300 or ext4dev module exists.
1302 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1303 while trying to close a filesystem can lead to infinite loops.
1304 (Addresses Red Hat Bugzilla #465679)
1306 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1307 will cause resize2fs to drop into an infinite loop. (Addresses Red
1308 Hat Bugzilla: #465984)
1310 Add a check in the Unix I/O functions in libext2fs so that when a
1311 device is opened read/write, return an error if the device is
1312 read-only using the BLKROGET ioctl.
1314 Fix debugfs's ncheck command so that it prints all of the names of
1315 hardlinks in the same directory.
1317 Fix a bug in libblkid so it correctly detects whether the ext4 and
1318 ext4dev filesystems are available, so that the ext4dev->ext4
1319 fallback code works correctly.
1324 Fix a parallel build problem by making sure util/subst is built before
1325 trying to build the lib/et directory. (Addresses Sourceforge Bug:
1328 Updated "make depend" information for crc16.o
1331 E2fsprogs 1.41.2 (October 2, 2008)
1332 ==================================
1334 Fix e2fsck's automatic blocksize detection. This fixes a regression
1335 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1336 specifies a block number using the -b option if the blocksize option
1337 isn't also specified using -B. Unfortunately, users very commonly
1338 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1339 superblock; in fack e2fsck will often suggest this kind of command
1342 Enhance the debugfs's "ncheck" command so it will print all of the
1343 pathnames for the specified inodes. (Previously, in some cases ncheck
1344 might not print a pathname for an inode at all if some of the other
1345 inodes had multiple hard links.)
1347 Enhance debugfs's "hash" command so the hash seed can be specified via
1348 a command-line option. In addition, allow the hash algorithm to be
1349 specified by name instead of just by number.
1351 Fix e2fsck so that we don't accidentally print the translation file's
1352 header when asking the user a custom question so there is no prompt
1353 defined for a particular problem record. For example, the question
1354 "Run journal anyway" will get the PO header tacked on because e2fsck
1355 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1372 with its man manpage.
1374 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
1375 and Sweedish translation from the Translation Project.
1377 Add documentation for the file I/O functions to the libext2fs.texinfo
1378 file. (Addresses Debian Bug: #484877)

1384 details. (Addresses Debian Bug: #497619)
1389 Fix a potential file descriptor leack in libcom_err by setting the
1390 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
1393 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
1394 has been carrying a patch for a long time to prevent a largely
1395 theoretical race condition if a multi-threaded application adds and
1396 removes error tables in multiple threads. Unfortunately SuSE's
1397 approach breaks compatibility by forcing applications to link and
1398 compile with the -pthread option; using pthread mutexes has
1399 historically been problematic. We fix this by using sem_post/sem_init
1402 Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
1403 Sourceforge Bug: #2087502)
1405 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
1406 libraries when using ELF shared libraries.
1408 Fix ELF shared library when building on systems that don't already
1409 have the e2fsprogs shared libraries already installed. (Addresses
1410 Sourceforge Bug: #2088537)
1412 Fix the pkg-config files so they work correctly when linking with
1413 static libraries and fix the include directory so programs don't have
1414 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
1415 instead. (Addresses Sourceforge Bug: #2089537)
1417 Make sure ext2fs_swab64() is compiled for all platforms, and not just
1418 for x86. (Addresses Debian Bug: #497515)
1420 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1421 non-x86 platforms. (They had been removed for x86 earlier.)
1423 Fix diet libc compilation support, which had bitrotted due to lack of
1424 TLC. Fixing this improves general portability.
1426 When installing the link library when using ELF shared libraries,
1427 avoid using absolute pathnames if the link library and the shared
1428 library are installed in the same directory. (Addresses Sourceforge
1431 Fix gen-tarball so it will work even if the top-level directory has
1432 been renamed to something other than "e2fsprogs". Also make
1433 gen-tarball print the size of the resulting tar.gz file.
1436 E2fsprogs 1.41.1 (September 1, 2008)
1437 ====================================
1439 Many people are forgetting to update their mke2fs.conf file, and this
1440 causes ext3, ext4, and ext4dev filesystems won't get created with the
1441 proper features enabled. We address this in two ways. First, mke2fs
1442 will issue a warning if there is not definition for an ext3, ext4, or
1443 ext4dev filesystem and the user is trying to create such a filesystem
1444 type. Secondly, when installing from a source build, "make install"
1445 will provide basic configuration file handling for /etc/mke2fs.conf.
1446 If it exists, and does not mention ext4dev, it will be moved aside to
1447 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1448 be installed. If the existing /etc/mke2fs.conf file does mention
1449 ext4dev, then "make install" will install official mke2fs.conf file as
1450 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1451 they should look to see if any changes need to be merged.
1453 The mke2fs program will now create the journal in the middle of the
1454 filesystem, since this minimizes seek times on average for fsync-heavy
1455 workloads. In addition, mke2fs will now create journals using extents
1456 for filesystems that support them. This results in a more efficient
1457 encoding for the journal since it eliminates the need for using
1460 The mke2fs program will avoid allocating an extra block to the
1461 journal. (Addresses Sourceforge Bug: #1483791)
1463 Mke2fs will correctly enforce the prohibition against features
1464 (specifically read-only features) in revision 0 filesystems. (Thanks
1465 to Benno Schulenberg for noticing this problem.)
1467 Mke2fs previously would occasionaly create some slightly non-optimally
1468 placed inode tables; this bug has been fixed.
1470 The mke2fs and tune2fs programs now print the correct usage message
1471 describing the maximum journal size. (Addresses Debian Bug: #491620)
1473 Add support for setting the default hash algorithm used in b-tree
1474 directories in tune2fs (from a command-line option) or mke2fs (via
1475 mke2fs.conf). In addition, change the default hash algorithm to
1476 half_md4, since it is faster and better.
1478 The blkid library will now recognize MacOS hfsx filesystems, and
1479 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1480 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1482 The blkid library has improved detection of JFS and HPFS filesystems.
1483 (Addresses Launchpad Bug: #255255)
1485 The blkid library is now much more efficiently handling devicemapper
1486 devices, mainly by no longer using the devicemapper library. This can
1487 speed up access for systems with a large number of device mapper
1490 Blkid had a number of cache validation bugs in libblkid that have been
1491 fixed. (Addresses Debian Bug: #493216)
1493 Resize2fs will now properly close out the "updating inode references"
1494 progress bar so there is a newline printed before printing the final
1495 "resize is successful" message.
1497 Resize2fs will now correctly handle filesystems with extents and/o
1498 uninitialized block groups correctly when file/directory blocks need
1499 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1500 is not present). To support this, the ext2fs library now supports
1501 initializing inode and block bitmaps that are not yet initialized when
1502 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1503 addition, e2fs_block_iterate2() can now support changing the location
1504 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1505 been optimized to avoid creating unnecessary new extents when updating
1506 the location of blocks in the extent tree. This will also help out
1507 e2fsck's recovery of obscurely corrupted filesystems with extents,
1508 when blocks are claimed by multiple inodes.
1510 Add support for on-line resizing ext4 filesystem with the flex_bg
1511 filesystem feature. The method for doing so is not optimal, but to do
1512 a better job will require kernel support.
1514 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1515 debugfs programs to not be able to read e2image files; the signed
1516 vs. unsigned bug in the code which read bitmaps from the e2image has
1517 been fixed. (Addresses Debian Bug: #495830)
1519 Resize2fs is now correctly managing the directory in-use counts when
1520 shrinking filesystems and directory inodes needed to be moved from one
1521 block group to another. This bug has been around since e2fsprogs
1522 1.26, and is largely harmless, but does cause a filesystem corruption
1523 which will be flagged by e2fsck after the filesystem has been shrunk.
1525 E2fsck will no longer issue spurious complaints about the inode size
1526 caused by very large extent-based files, and by blocks reallocated
1527 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1528 Kernel Bugzilla: #11341)
1530 Mke2fs will now set the creation timestamp on the lost+found directory
1531 and the root directory. (More generally, all new inodes created using
1532 the ext2fs library will correctly set the creation timestamp.)
1534 E2fsck now correctly calculates ind/dind/tind statistics in the
1535 presence of extent-based files. In addition, "e2fsck -v" will report
1536 statistics of the depth of extent trees in the filesystem. E2fsck can
1537 also give an inode fragmentation report using "e2fsck -E fragcheck"
1538 which can be useful when debugging the kernel block allocation
1541 Fix support for empty directory blocks in ext4 filesystems with 64k
1542 blocksize filesystems.
1544 E2fsck will now print the depth of corrupt htree directories.
1546 Debugfs's htree command now correctly understands extent-based
1547 directories. It will also print out the minor hash as well as the
1550 Debugfs has a new command which will print the supported features of
1551 e2fsprogs, to enable scripts to know whether the installed version of
1552 e2fsprogs can support a specific feature.
1554 Debugfs will now write files using extents for filesystems that
1557 The error message printed by "tune2fs -I" if the inode size was too
1558 small was rather confusing, so it has been improved. Also, we won't
1559 try to create an undo log until we know that command-line-specified
1560 parameters such as "tune2fs -I <inode size>" are valid.
1562 Given some filesystems found "in the wild" that had non-zero block
1563 group checksums even though the uninit_bg/gdt_sum feature was not
1564 enabled, e2fsck would issue spurious error messages. Teach
1565 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1566 entirely if the feature flag is not set. (Addresses Debian Bug:
1569 The blkid program will now print out a user-friendly listing of all of
1570 the block devices in the system and what they contain when given the
1571 -L option. (Addresses Debian Bug: #490527)
1573 The filefrag program now has a more accurate calculation for the
1574 number of ideal extents. (Addresses Debian Bug: #458306)
1576 The test I/O manager is now enabled by default, but its overhead is
1577 only incurred when it would be enabled via the TEST_IO_FLAGS or
1578 TEST_IO_BLOCK environment variables.
1580 Typographical errors in various program strings and usage messages
1581 have been fixed; most of these were pointed out by the e2fsprogs
1582 message catalog translators. (Thanks, translators!)

1607 Sourceforge Bug: #2019287)
1609 The ext2fs_extent_set_bmap() had some bugs when setting the first
1610 block in a file, or when replacing a single block extent. Those cases
1611 fortunately were came up relatively rarely when e2fsck was checking
1612 files, but caused some problems when resize2fs was shrinking

1623 Ext2ed was failing to build because masix support had been removed in
1624 the rest of e2fsprogs, so ext2ed no longer has masix support, either.

1627 it is set when configure is called. (Addresses Sourceforge Feature
1630 Libuuid is now more portable to the Windows platform. (Addresses
1631 Sourceforge Feature Request: #1937287)
1633 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1634 bare echo commands so that configure flags such as --quiet work
1635 correctly. (Addresses Sourceforge Patches: #2058794)
1637 A few uses of sprintf have been removed from the ext2fs library to
1638 make life easier for bootloaders with a limited libc environment.

1646 passed to it earlier, to avoid doing some needless work when it would
1649 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1650 top-level Makefile. That automatic rule is used to better support
1651 SCCS, but it caused problems for a particular niche distribution which
1652 likes to use configure.sh files to store the configure options used to
1653 build a package. Unfortuntaely GNU make will use the configure.sh to
1654 replace the configure script, resulting in a self-inflicted fork bomb
1655 leading to an out-of-memory crash.
1657 To support old GNU C compilers don't use C99/C++ comments, but only
1658 K&R style comments, and don't try to use __builtin_expect if __GNUC__
1659 is less than 3. (__builtin_expect is only supported for gcc versions
1660 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1661 this is an optimization, we only try to use __builtin_expect for gcc 3
1664 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
1665 __LITTLE_ENDIAN, which are only defined by glibc's header files and
1666 hence isn't portable.
1668 For the convenience for some distributions that need a static tune2fs,
1669 the Makefile for misc/ now has a tune2fs.static target.
1671 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1672 for extent-based files
1674 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1677 All source files no longer have any trailing white space.
1679 The io_channel_read_blk64() and io_channel_write_blk64() functions are
1680 now functions instead of C preprocessor macros to provide better
1681 forward compatibility.

1691 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
1693 * Scripts do not assume that /bin/true is always in /bin
1694 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
1695 * Flush stdio handles before calling setbuf(), since Solaris will
1696 discard any pending output to the stream.
1697 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
1698 picky about which C compiler can beused for SUSv3 conformance.
1699 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
1700 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
1701 Since we need some SUSv3 functions, consistently use SUSv3 so
1702 that e2fsprogs will build on Solaris using c99.
1703 * Solaris C99 does not support varargs C preprocessor macros
1704 * Solaris header files pollute the C namespace if in/netinet.h
1705 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
1707 * Solaris ships with a pathetically ancient shell in /bin/sh so we
1708 avoid the use of various more avanced shell constructs such as $().
1710 The "make rpm" command will now take some extra configure optiosn from
1711 the build environment without needing to patch the source tree.
1713 The ext2fs_add_dir_block() function will now grow the dblist more
1714 aggressively as an optimization to avoid copying the array too often.
1716 The e2fsck_write_bitmaps() will write the block and inode bitmaps
1717 together instead of in two passes.
1720 E2fsprogs 1.41 (July 10, 2008)
1721 ==============================
1723 Add support for ext4 filesystem features, in particular extents,
1724 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
1725 support for checking journal checksums. Debugfs will print new
1726 superblock and inode fields that were defined for ext4. For example,
1727 the nanosecond and i_version fields of an inode, and the
1728 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1729 Note: Resize2fs doesn't currently support the combination of flex_bg
1730 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
1732 Tune2fs can support migrating a filesystem from using 128 byte inodes
1733 to 256 byte inodes, so it can take advantage of the full features of
1736 Add support for "undo" support. E2fsck and mke2fs can optionally
1737 record an undo log which can replayed by the program e2undo.
1739 E2fsck could damage a filesystem by trying to relocate inode tables
1740 due to corrupted block group descriptors, where the attempted inode
1741 table relocation would do far more harm than good. E2fsck has been
1742 fixed to detect this these sorts of corrupted block group descriptors
1743 much earlier in e2fsck processing, so it can try to use the backup
1744 superblock and block group descriptors first. This should be a much
1745 better strategy for recovering these types of corrupted filesystems.
1746 (Addresses Sourceforge Bug: #1840291)
1748 E2fsck will display a more understandable message when the last check
1749 field in the superblock is in the future. (Addresses Debian Bug:

1759 Fix mke2fs to use a default block size of 4k when formatting an
1760 external journal device. This is done by using a fixed filesystem
1761 type list that consists only of the single filesystem type "journal"
1762 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
1763 Debian Bug: #488663)
1765 Speed up how mke2fs writes the journal data blocks by writing the disk
1766 blocks in larger chunks.
1768 Fix blkid handling of stale devices. Fix a bug which could cause a
1769 core dump while garbage collecting the blkid cache, and assure that
1770 blkid_find_dev_with_tag() never returns a non-existent device. Also,
1771 if a filesystem is found at a new /dev location, eliminate any
1772 duplicate stale entries which can not be verified.
1773 (Addresses Debian Bugs: #487758, #487783)
1775 Add more paranoid checks for LVM volumes and swap partitions in
1776 blkid's probe function, to reduce the chances of false positives.
1778 The mke2fs program now has a much more sophisticated system for
1779 controlling configuration parameters of a newly created filesystem
1780 based on a split filesystem and usage type system. The -t option to
1781 mke2fs was a deprecated alias to -c; it now specifies a filesystem
1782 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1783 separated usage list. The filesystem type information and type
1784 information is used to extract configuration parameters from the
1785 /etc/mke2fs.conf file.
1787 The mke2fs program will no longer complain and request the -f option
1788 when the user tries to create a filesystem with greater than 2**31
1791 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1792 adjust the mke2fs.conf file so filesystems for the Hurd are created
1793 with a blocksize of 4096 and inode size of 128, which is all it knows
1794 how to handle. (Addresses Debian Bug: #471977)
1796 Mke2fs will always make sure that lost+found always has at least 2
1797 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1799 Resize2fs will now print the minimum needed filesystem size if given
1800 the -P option, and will resize the filesystem to the smallest possible
1801 size if given the -M option.
1803 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1804 blocks are consumed during an off-line resize.
1806 The "ls" command in debugfs now supports the -p option, which causes
1807 it to quote the filenames so that spaces or tabs in directory entries
1808 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
1809 Sourceforge Feature Request: #1201667)
1811 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1814 The chattr program will return a non-zero exit code in case of
1815 failures, and error messages can be suppressed with the -f option.
1816 (Addresses Red Hat Bugzilla: #180596)
1818 Fix a bug in badblocks which caused it to overrun an array and likely
1819 crash if more than 8 test patterns are specified using the -t option.
1820 (Addresses Debian Bug: #487298)
1822 Add support to badblocks to limit how quickly it reads from the disk
1823 drive (so it can be used for background scrubbing), and so it will
1824 abort after finding a given number of errors.
1826 Remove support for the legacy big-endian filesystem format which only
1827 existed on extremely long-dead PowerPC kernels almost a decade ago.
1829 Remove MASIX support from e2fsprogs.
1831 Add I/O statistics reporting to e2fsck.
1833 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,

1837 details. (Addresses Debian Bugs: #487443, #487675, #490003)

1858 Clean up the badblocks group so to make it more portable and robust.
1860 Avoid using predictable filenames in /tmp in blkid's regression test
1861 suite. Also remove bashism's in the regression test script.
1863 If the configure script is given --with-diet-libc, don't use thread
1864 local storage, since diet libc doesn't support TLS. (Addresses
1865 Sourceforge Bug: #2000654)
1867 Fix the blkid regression test suite to tolerate older versions of
1868 mkswap that don't support the -U option.
1870 A few library routines have been converted to support 64-bit block
1871 numbers; in particular, the I/O manager functions, the test_io,
1872 inode_io, and unix_io managers have all be converted to support 64-bit
1875 Debugfs can now be extended for use by test programs. See
1876 lib/ext2fs/extents.c for an example for how it can be used. The test
1877 program links against the debugfs object files, and provides
1878 additional commands by defining an auxiliary libss command table.
1880 The lazy_bg filesystem feature, which was only used by developer's
1881 testing, has been removed since it has been largely supplanted by
1882 uninit_bg. This also simplifies the code.
1885 E2fsprogs 1.40.11 (June 17, 2008)
1886 =================================
1888 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
1889 percentage of reserved blocks. (Addresses Debian Bug: #452639)
1891 Updated Spanish and Catalan translations.

1904 Fix marginal C code in probe_lvm2() function to the blkid library more
1905 portable for older compilers.
1907 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
1909 Fix ext2fs_swap{16,32,64} functions so they can be used by external
1910 applications on big-endian machines. (Addresses Debian Bug: #484879)
1913 E2fsprogs 1.40.10 (May 21, 2008)
1914 ================================
1916 When deciding whether or not to revalidate a blkid cache entry, if the
1917 device's mtime is newer than the last time the cached entry was
1918 validated, force a revalidation.
1920 Fix a potential data corruption bug in e2fsck in the journal replay.
1921 The chances of this is happening is extremely remote, especially the
1922 default data=ordered or data=writeback modes. However, if a block
1923 which has been journalled starts with the first four bytes 0xc03b3998,
1924 when e2fsck replays the journal, those four bytes will be replaced
1925 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1926 metadata to begin with those fatal 4 byte sequence, and unless
1927 data=ordered mode is in use, data blocks are never journaled.
1929 Updated German, Dutch, Sweedish, and Vietnamese translations.
1934 Fixed various Debian packaging issues --- see debian/changelog for
1937 Remove default sizes of types when cross compiling, since autoconf
1938 2.50 can figure this out automatically now.
1941 E2fsprogs 1.40.9 (April 27, 2008)
1942 =================================
1944 SuSE's security team audited uuidd and came up with a few minor
1945 issues. None of them are serious given that uuidd runs setuid as a
1946 unprivileged user which has no special access other than libuuid
1947 directory, but it's good to get them fixed.
1949 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1950 work correctly with in-inode extended attributes.
1952 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
1955 Debugfs will avoid using a pager if the standard output is not a tty.
1957 Fix debugfs and tune2fs to correctly handle daylight savings time when
1958 parsing a time string.
1960 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1962 Fix fsck completion bars when multiple filesystems were being checked
1963 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
1964 #203323, Addresses Sourceforge Bug: #1926023)
1966 Fix fsck so that progress information is sent back correctly when
1967 multiple filesystems are being check and the output of fsck is being
1968 redirected to a file descriptor. Also, include the device name (w/o
1969 spaces) in the progress information sent back via a file descriptor.
1970 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
1973 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
1975 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
1976 signal to its child process.
1978 Fix mke2fs's creation of are resize inode when there is a non-standard
1979 s_first_data_block setting.
1981 Fix bug in blkid when run by an unprivileged user; most devices were
1982 not reported correctly. 9Addresses Launchpad Bug: #220275)
1984 Mke2fs will not allow the logically incorect combination of
1985 resize_inode and meta_bg, which had previously caused mke2fs to create
1986 a corrupt fileystem.
1988 Fix fsck in German locales so that a 'j' means yes.

1995 Fixed various Debian packaging issues --- see debian/changelog for
1998 Update valgrind options in test_script to work with valgrind 3.2.3
2000 Update texinfo.tex to a much newer version from the FSF.
2002 Remove bashism for configure script and from the lib/ss Makefile.

2005 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
2007 Fix build system so that if texinfo is not installed, it won't print a
2008 (harmless) error message.
2011 E2fsprogs 1.40.8 (March 13, 2008)
2012 =================================
2014 Fixed e2image -I so it works on image files which are larger than 2GB.
2016 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
2017 the size is larger than the number of blocks found in the inode, don't
2018 try to allocate extra empty blocks at the end of the directory to make
2019 up the difference; there's no point to doing that. In addition, if
2020 the size is not a multiple of a blocksize, always fix it.
2022 E2fsck handled a pass 2 "should never happen error" by not giving
2023 enough information and then core dumping. Unfortunately, it was all
2024 too easy to trigger the "should never happen" situation if a
2025 directory's inode size was not correct. This has been fixed, but
2026 e2fsck has also been taught how to handle this situation more
2027 gracefully, by simply removing the inode hash tree information, so
2028 that it can be rebuilt again after e2fsck's pass 3. (Addresses
2029 Launchpad Bug: #129395)
2031 Resize2fs had a bug resizing large inodes with extended attributes
2032 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2033 completely on big-endian systems such as PowerPC. The bug should be
2034 completely fixed now. Yay for regression test suites. (Addresses Red
2035 Hat Bugzilla: #434893)
2037 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
2038 translations. Many thanks to Philipp Thomas from Novell for stepping
2039 up to become the new German translation maintainer! (Addresses Debian
2040 Bugs: #302512, #370247, #401092, #412882).
2042 When e2fsck is clearing a corrupt inode's HTREE directory information,
2043 make it clear that it is just clearing the HTREE information, not the
2046 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2051 Add new functions, ext2fs_dblist_get_last() and
2052 ext2fs_dblist_drop_last(), which allows the caller to examine the last
2053 directory block entry added to the list, and to drop if it necessary.
2055 Fixed a portability problem in libblkid with DJGPP.
2057 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
2058 to Philipp Thomas for pointing this out.
2060 If the info files are not built, change "make install" so it doesn't
2061 fail with an error code.
2064 E2fsprogs 1.40.7 (February 28, 2008)
2065 ====================================
2067 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2068 depreciate the -s option, since it can result in filesystems which
2069 e2fsck can't fix easily. There are very good reasons for wanting to
2070 disable sparse_super; users who wants to turn off sparse_super can use
2071 debugfs. (Addresses Sourceforge Bug: #1840286)
2073 Add missing options to mke2fs's usage message. (Addresses Sourceforge
2076 Fix bug in resize2fs when large (greater than 128 byte) inodes are
2077 moved when a filesystem is shrunk; it was only moving the first 128
2078 bytes, so extended attributes were not getting moved. (Addresses Red
2079 Hat Bugzilla: #434893)
2081 E2fsck now prints an explicit message when the bad block inode is
2082 updated, to avoid confusion about why the filesystem was modified.
2083 (Addresses Sourceforge Bug: #756460)
2085 Allow mke2fs and tune2fs manipulate the large_file feature.
2086 Previously we just let the kernel and e2fsck do this automatically,
2087 but e2fsck will no longer automatically clear the large_file feature.
2088 It still isn't really necessary to worry about this feature flag
2089 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
2092 Suppress message about an old-style fstab if the fstab file is empty.
2093 (Addresses Debian Bug: #468176)
2095 Fix (really minor) bug in debugfs's find_free_block so it avoids
2096 reporting a free block more than once if there are too few free blocks
2097 in the filesystem. (Addresses Sourceforge Bug: #1096315)
2099 Change e2fsck to no longer clear the LARGE_FILES feature flag
2100 automatically, when there are no more > 2GB files in the filesystem.
2101 It's been almost a decade since there have been kernels that don't
2102 support this flag, and e2fsck clears it quietly without telling the
2103 user why the filesystem has been changed.
2105 Fix bug which could cause libblkid to seg fault if a device mapper
2106 volume disappears while it is being probed. (Addresses RedHat
2109 Inhance e2fsck's reporting of unsupported filesystem feature flags.
2110 (Addresses Sourceforge Feature Request: #1175808)
2112 Fix option syntax in dumpe2fs for explicit superblock and blocksize
2113 parameters. What was currently documented in the man page has been
2114 broken for some time, due to getopt() implementation changes. The
2115 option sytax has been changed to one which is can be more portable
2116 supported and which is consistent with the format for extended options
2117 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
2119 Add support to tune2fs to clear the resize_inode feature. This
2120 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
2122 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
2125 Add support for setting RAID stride and stripe-width via mke2fs and

2152 details. (Addresses Debian Bug: #466929)
2154 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
2155 partially filled-in filesystem object on an error, so that e2fsck can
2156 print more intelligent error messages.
2158 Add a new function e2p_edit_feature2() which allows the caller to
2159 specify which feature flags are OK to set or clear, and which returns
2160 more specific information about feature flags which are not allowed to
2163 Set the C locale in the test_script driver since it uses [A-Za-z].

2170 absolutely needed. (i.e., when using parsing a WIP-style version
2171 number) (Addresses Sourceforge Bug: #1893024)
2173 Add portability checks to support compilation under DJGPP.
2175 Update to the latest samba tdb code before the LGPLv3 change, which

2187 ===================================
2189 Add support for returning labels for UDF filesystems in the blkid
2192 Fix bug in the blkid library where cached filesystems was not being
2193 flushed when opening USB devices returned the error ENOMEDIUM.
2194 (Addresses Debian Bug: #463787)
2196 Added logic to the blkid library to automatically choose whether a
2197 filesystem should be mounted as ext4 or ext4dev, as appropriate.
2199 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
2201 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
2202 configured with --enable-jbd-debug.
2204 Document the BLKID_FILE environment variable in the libblkid man page

2212 details. (Addresses Debian Bugs: #436058)
2214 Don't try to create $DESTDIR/etc/init.d as part of make install as we
2215 don't install the init.d script (and it's not the recommended way to

2219 threads try to format an unknown error code at the same time in the
2223 E2fsprogs 1.40.5 (January 27, 2008)
2224 ===================================
2226 Fix a potential overflow big in e2image if the device name is too
2229 Mke2fs will now create new filesystems with 256 byte inodes and the
2230 ext_attr feature flag by default. This allows for much better future
2231 compatibity with ext4 and speeds up extended attributes even on ext3
2234 Teach e2fsck to ignore certain "safe" filesystem features which are
2235 set automatically by the kernel. Having the kernel set features
2236 automagically behind the user's back is a bad idea, and we should try
2237 to break the kernel of this habit, especially for the newer ext4
2238 feature flags. But for now, we will try to avoid needless full checks
2239 which can annoy users who are doing fresh installs.
2241 Add support in tune2fs and mke2fs for making a filesystem as being "ok
2242 to be used with test kernel code". This will be needed for using test
2243 filesystems with the latest ext4 kernel code.
2245 Change e2fsck -fD so that it sorts non-htree directories by inode
2246 numbers instead of by name, since that optimizes performances much
2247 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
2249 If e2image fills the disk, fix it so it exits right away instead of
2250 spewing large numbers of error messages.
2251 (Addresses-Sourceforge-Feature-Request: #606508)
2253 If ftruncate64() is not available for resize2fs, let it use ftrucate()
2254 instead, but have it check to see if the size would get truncated, and
2255 skip calling ftruncate in that case.
2257 Add support for detecting HFS+ filesystems in the blkid library.
2259 Add supprt in the blkid library for ext4/ext4dev filesystems.
2261 Fix a bug in blkid where it could die on a floating point exception
2262 when presented with a corrupt reiserfs image.
2264 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
2265 such that UUID string is a fixed length.
2267 Add sample python bindings for the uuid library to the contrib
2268 directory. (Addresses-Sourceforge-Patches: #778817)

2274 Allow the debugfs 'undel' command to undelete an inode without linking

2276 allocating blocks that could overwrite some yet-to-be-recovered
2277 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)

2315 Improve time-based UUID generation. A new daemon uuidd, is started
2316 automatically by libuuid if necessary. This daemon is setuid to allow
2317 updates to /var/lib/libuuid, so the clock sequence number can be

2374 exploits exist, but main concern is where an untrusted user who
2375 possesses privileged access in a guest Xen environment could corrupt a
2376 filesystem which is then accessed by the pygrub program, running as
2377 root in the dom0 host environment, thus allowing the untrusted user to
2378 gain privileged access in the host OS. Thanks to the McAfee AVERT
2379 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2381 Fix hueristics in blkid which could cause a disk without partitions to
2382 be incorrectly skipped when a loopback device is present. (Addresses
2383 Red Hat Bugzilla #400321.)
2385 Fix e2image so that in raw mode it does not create an image file which
2386 is one byte too large.
2388 Change mke2fs's usage message so it recommends the preferred -E option
2389 instead of the deprecated -R option.
2391 Enhance the blkid library so it will recognize squashfs filesystems.
2392 (Addresses Red Hat Bugzilla #305151.)
2394 Enhance e2fsck so it will force the backup superblocks to be backed up
2395 if the filesystem is consistent and key constants have been changed
2396 (i.e., by an on-line resize) or by e2fsck in the course of its
2399 Enhance blkid's detection of FAT filesystems; so that USB disks with
2400 only a single bootable partition will not get missed.
2402 E2fsck will no longer mark a filesystem as invalid if it has time
2403 errors (i.e., if superblock mount time or last write time is in the
2404 future) and the user refuses to fix the problem.
2406 The Ubuntu init scripts don't properly set the system time correctly
2407 from hardware clock if the hardware clock is configured to tick local
2408 time instead of GMT time. Work around this as best as we can by
2409 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2410 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2413 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2414 Hat Bugzilla #151533.)
2416 Fix e2fsck so that if the superblock is corrupt, but still looks
2417 vaguely like an ext2/3/4 superblock, that it automatically tries to
2418 fall back to the backup superblock, instead of failing with a hard
2421 Make the e2fsprogs program more robust so that they will not crash
2422 when opening a corrupt filesystem where s_inode_size is zero.
2424 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2425 arguments are detected as such and the parse error is reported to the
2426 user. (Addresses Debian Bug #435381.)
2428 Change e2fsck so it will not complain if a file has blocks reallocated
2429 up to the next multiple of a system's page size.
2431 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2432 about (valid) filesystems where the inode table extends to the last
2433 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2435 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2436 allocating inode tables for some relatively rare odd disk sizes.
2437 (Addresses Red Hat Bugzilla #241767.)
2439 Add Catalan translation and update Dutch and Swedish translations
2440 from the Translation Project.
2442 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2443 still had an issue when trying to figure out whether we need to
2444 byte-swap fast symlinks that contained extended attributes.
2446 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2447 (Addresses SourceForge Bug #1821333.)
2453 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
2455 Add "make check" to the RPM spec file
2457 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2458 works correctly when the prefix is not the root directory.
2460 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2461 clena up after themselves by deleting the test.img temporary file
2462 after completing the test.
2464 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2465 first directory entry in a directory block and the last directory
2466 entry in the previous directory block is not in use. Fortunately
2467 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2468 places where it is extremely unlikely to run into this corner case.
2470 Fix missing dependency which would cuase parallel builds to fail.
2471 (Addresses Sourceforge Bug #1842331.)
2473 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2474 calling open(O_CREATE) with a missing mode parameter.
2476 Fix the test_ss.c in lib/ss so it can be used as an example
2477 application program for the library as well as a regression test
2480 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2481 are properly passed back up through the call stack.
2483 E2fsprogs 1.40.2 (July 12, 2007)
2484 ================================
2486 A recent change to e2fsck_add_dir_info() to use tdb files to check
2487 filesystems with a very large number of filesystems had a typo which
2488 caused us to resize the wrong data structure. This would cause a
2489 array overrun leading to malloc pointer corruptions and segfaults.
2490 Since we normally can very accurately predict how big the the dirinfo
2491 array needs to be, this bug only got triggered on very badly corrupted
2494 Fix a bug in e2fsck which caused it to incorrectly salvange
2495 directories when the last entry's rec_len is bogusly too big. This
2496 resulted in a nonsense filesystem corruption to be reported, and
2497 required a second run of e2fsck to fully fix up the directory.
2499 Update tune2fs man page to include more discussion of reserved blocks
2500 (Addresses Launchpad bug #47817)
2502 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2506 E2fsprogs 1.40.1 (July 7, 2007)
2507 ===============================
2509 Fix bug which could cause libblkid to loop forever. When revalidating
2510 a partition where there is obsolete information in /etc/blkid.tab, we
2511 end up freeing a the type tag without clearing dev->bid_type, causing
2512 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2514 The Turkish translation has a bug in it where it has the translation
2515 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2516 @E, recursively, forever, until the stack fills up and e2fsck core
2517 dumps. We fix this by making e2fsck stop @-expansions after a
2518 recursive depth of 10, which is far more than we need.
2519 (Addresses Sourceforge Bug: #1646081)
2521 Compile the default mke2fs.conf into mke2fs program. People are
2522 getting surprised by mke2fs creating filesystems with different
2523 defaults than earlier versions of mke2fs if mke2fs.conf is not
2524 present. So we now create a built in version of mke2fs.conf file
2525 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2526 (Addresses SourceforgeBug: #1745818)
2528 Improve the config/parse_types.sh helper script. Fix a potential
2529 security problem if e2fsprogs is built as root (as Gentoo does!). In
2530 addition fix the script and how it is called from the configure script
2531 so that it does the right thing when cross-compiling. (Fixes Gentoo
2534 Update Vietnamese, French, and Dutch PO files from the Translation
2535 Project. Also created a new e2fsprogs.pot file for translator.
2537 Fix bogus strip permission errors when building under Debian. When
2538 building the e2fsprogs dpkg's, the dh_strip command emits a large
2539 number of error messages caused by the permissions not being right.
2540 So run dh_fixperms before running dh_strip.
2545 Add new function: profile_set_default(). This function sets the value
2546 of the pseudo file "<default>". If the file "<default>" had
2547 previously been passed to profile_init(), then def_string parameter
2548 will be parsed and used as the profile information for the "<default>"
2551 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2552 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2553 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2555 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2556 priority" environment variable that overrides all others, where as
2557 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2558 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2559 the all the rest are set. This will assure that the locale when
2560 running the test suites is the "C" locale. (Obviates Gentoo patch:
2561 e2fsprogs-1.38-tests-locale.patch)
2564 E2fsprogs 1.40 (June 29, 2007)
2565 ==============================
2567 Fix divide by zero error in blkid's NTFS probing logic.
2569 Add new blkid -g option which causes the blkid cache to be garbage
2572 Fix a bug in libblkid which could cause the internal field bid_type to
2573 become corrupted. Fortunately bid_type isn't used much, and bid_label
2574 and bid_uuid is only used by debugging code, so the impact of this bug
2577 Mke2fs will now store the RAID stride value when a filesystem is
2578 created with a requested RAID stride, and then use it automatically in
2581 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2582 isn't too big. In some cases Lustre users have tried specifying an
2583 inode size of 4096 bytes, while keeping an inode ratio of one inode
2586 Improve sanity check in e2fsck's algorithm for finding a backup
2587 superblock, so that it won't accidentally find a superblock that was
2588 located in the journal, and then later reject it as being not a valid
2591 Fix e2fsck get_size logic so that it will work with the Linux floppy
2592 driver. The Linux floppy driver is a bit different from the other
2593 block device drivers, in that if the device has been opened with
2594 O_EXCL, it disallows another open(), even if the second open() does
2595 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2597 Fix error checking of badblock's last-block and start-block arguments.
2598 (Addresses Debian Bug: #416477)
2600 Fix e2fsck so that it doesn't overwrite the backup superblocks when
2601 recovering a journal until the master superblock has been confirmed as
2604 Change the blkid library to be much more paranoid about concluding
2605 that a partition contains an NTFS filesystem, and fetch the UUID and
2606 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
2609 Factor out the code which sets the default journal size and move it
2612 Enhance e2fsck so it will recreate the ext3 journal if the original
2613 journal inode was cleared to due it being corrupt after finishing the
2616 Fix e2fsck so that it updates the journal inode if it is corrupted and
2617 the backup journal information from the superblock was successfully
2618 used to recover the filesystem.
2620 Fix e2fsck so that it checks all of the blocks in the journal inode
2621 for validity. The original code only checked the direct blocks to
2622 make sure the journal inode was sane. Unfortunately, if some or all
2623 of the indirect or doubly indirect blocks were corrupted, this would
2626 Add support in blkid to detect LUKS encrypted partitions.
2628 Add extra sanity checks for extended attributes in the case where the
2629 size is zero but the offset is very large.
2631 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
2632 and ext2fs_get_next_inode_full().
2634 Clarify the copyright licenses used by the various libraries in
2635 the top-level COPYING file (Red Hat Bugzilla: 166058)
2637 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
2639 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
2641 Remove check in e2fsck which requires EA's in inodes to be sorted;
2642 they don't need to be sorted, and e2fsck was previously wrongly
2643 clearing unsorted EA's stored in the inode structure.
2645 Allow mke2fs or tune2fs to create a substantially larger journal (up
2646 to 10,240,000 blocks).
2648 Fix MD superblock detection, and make sure the correct UUID is
2649 reported from the MD superblock.
2651 Fix a signed vs. unsigned bug in debugfs.
2653 Enhance debugfs's date parser so that it accepts integer values.
2655 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
2656 file with multiply claimed blocks is hard linked. or not at all if the
2657 root directory contains shared blocks
2659 Enhance debugfs so it can modify the block group descriptors using the
2660 command set_block_group_descriptor.
2662 Improve e2fsck's reporting of I/O errors so it's clearer what it was
2663 trying to do when an error happens
2665 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
2666 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
2667 #232663 and LTC Bugzilla: #27634)
2669 Fix potential file descriptor leak in ext2fs_get_device_size() in an

2674 Impove badblocks -n/-w exclusive usage message.
2676 Fix dump_unused segfault in debugfs when a filesystem is not open
2678 Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
2680 Allow the debugfs lcd command to work w/o a filesystem being open.
2681 (Addresses LTC Bugzilla #27513)
2683 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
2684 field on the first pass.
2686 Fix e2fsck to set the file type of the '..' entry when connecting
2687 a directory to lost+found. (Addresses Lustre Bug: #11645)
2689 Enhance e2fsck to recover directories whose modes field were corrupted
2690 to look like special files. This is probably only useful in
2691 artificial test cases, but it will be useful if we ever do the "inodes
2692 in directory" idea for ext4.
2694 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
2697 Fix resize2fs parsing of size parameter (in sector units). This was
2698 actually a bug in libe2p's parse_num_blocks() function. When handling
2699 the 's' suffix, it was ignoring the blocksize information passed in
2700 from the caller and always interpreting the number in terms of a 1k
2701 blocksize. (Addresses Debian Bug: #408298)
2703 There was a floating point precision error which could cause e2fsck to
2704 loop forever on really big filesystems with a large inode count.
2705 (Addresses Debian Bug: #411838)
2707 Fix memory leak in ext2fs_write_new_inode()
2709 Add support for using a scratch files directory to reduce e2fsck's
2710 memory utilization on really big filesystems. This uses the TDB
2711 library. See the [scratch_files] section of the e2fsck.conf man page
2714 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
2715 platform (Addresses Debian Bug: #397044)
2717 Add explanatory message to badblocks that -n and -w are mutually exclusive
2718 (Addresses Debian Bug: #371869)
2720 Allow debugfs and dumpe2fs to support fs features under development.
2722 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2723 ext2fs_open() , which allows application to open filesystes with features
2724 which are currently only partially supported by e2fsprogs.
2726 Allow unix_io to support offsets greater than 2G (Addresses
2727 SourceForge Bug: #1547922)
2729 Fixed overflow and signed/unsigned problems caused by the number of
2730 blocks or inodes exceeding 2**31 or being close to 2**32-1.
2732 Add support for unsigned directory hash calculations with hints in the
2733 superblock to fix cross-architectural portability for htree
2734 directories with filenames where the high 8th bit is set. (Addresses
2737 Fix resize2fs so that it gives user-intelligible error messages if the
2738 filesystem or the kernel does not support on-line resizing.
2739 (Addresses Debian Bug: #380548)
2741 Require mke2fs -F -F for really dangerous operations, since -F is
2742 needed for less dangerous operations such as creating filesystems
2743 images in regular files, or creating filesystems on whole block
2744 devices. These relatively innocuous usages should NOT be confused
2745 with running mke2fs on an apparently-mounted or in-use filesystem.
2747 Allow the default inode size to be specified into the mke2fs.conf
2750 Make the smallest default journal size is big enough so that on-line
2751 resizing should always work.
2753 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
2756 Fix debugfs coredump when lsdel is run without an open filesystem
2757 (Addresses Debian Bug: #378335)
2759 Fix debugfs display bug us that bytes that have the high bit set are
2760 displayed as "ec" instead of "ffffffec".
2762 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
2764 Device mapper scanning wasn't working in the blkid library because the
2765 pathnames had an extra "/dev" when they were being probed.
2767 Add GFS/GFS2 support to the blkid library.
2769 Fix blkid support of empty FAT filesystem labels.
2771 Avoid recursing forever (or for a long time) when the blkid library
2772 searches for a device and there are symlinks to directories in /dev.
2774 Avoid unaligned halfword access in blkid when accessing FAT
2775 superblocks, as this will cause Sparc/Solaris systems to throw a

2782 Improve the (non-installed, for experts only) findsuper program by
2783 printing the uuid and label from the superblocks, as well as the
2784 starting and ending offsets of the filesystem given the information in
2785 the superblock. Omit by default printing superblocks that are likely
2786 found in located in an ext3 journal unless an explicit -j option is
2789 Updated Spanish, French and Dutch translations and added Catalan
2790 translation. (Addresses Debian bug: #411562)
2792 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2793 determining a partition's size, since binary searching to determine
2794 the device doesn't work on FreeBSD.
2796 Documentation about UUID's is available in enough places, and it's
2797 awkward to deal with debian-legal's insanities. So I'm caving in the
2798 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2799 don't have do the dfsg tarball. Also remove the rule that only tried
2800 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2801 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
2803 Fix the info-dir line so that the menu name does not contain a .info
2804 prefix. First of all, it's ugly, secondly, it causes the install-info
2805 command to fail to remove the com_err info file from the
2806 /usr/share/info/dir file when the comerr-dev package is removed and
2807 purged. (Addresses Debian Bug: #401711)
2809 Fixed spelling mistakes, typos, and otherwise clarified man pages.

2820 E2fsck now supports the %It expansion when printing a problem report.
2821 It will print the type of the inode in the problem context.
2823 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
2824 (Addresses Sourceforge Bug: #1565561)
2826 Remove unused variables and other lint/gcc -Wall cleanups
2828 Add check to ext2fs_get_device_size() so it will return EFBIG for for
2829 filesystems contained in regular files where the filesystem image size
2830 is returned by stat64().
2832 Set local environment variables to C so mk_cmds and compile_et always
2833 work. (Addresses SourceForge Bug: #1532177)
2835 Added the 64-bit byte swapping function ext2fs_swab64().
2837 Added two new helper functions to prevent 2**31/2**32-1 overflow
2838 problems: ext2fs_div_ceil() and e2p_percent().
2840 Create new ext2fs library inline functions ext2fs_group_first_block()
2841 and ext2fs_group_last_block() in order to calculate the starting and
2842 ending blocks in a block group.
2844 Create the generated files read-only to remind developers not to edit them.
2846 Add support for autoconf 2.60 (with backwards compatibility for older
2847 versions of autoconf).
2849 Added an "make rpm" target to top-level Makefile
2851 Added various FreeBSD portability fixes.
2853 Exclude mercurial files from the RPM build tree to speed up copy/build.
2855 Use root_sysconfdir to define the locations of mke2fs.conf and
2856 e2fsck.conf instead of using a hard-coded /etc pathname.
2858 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2860 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2862 If diff -u is supported, use it to report test failures.
2864 Updates/improvements to RPM spec file
2866 Add on-disk format definitions for the following new features:
2867 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2868 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2869 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2871 Add a new make target "checked-failed" in the tests directory which
2872 reruns any failed tests
2874 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2876 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2877 pointer dereferences, memory leaks, etc. None were security-criticial
2880 Fix up usage and decrement error messages in the test_icount program
2882 Add debugging code to the com_err library; if the environment variable
2883 COMERR_DEBUG is set to 1, print out debugging messages as error tables
2884 are added and removed from the com_err library. If the
2885 COMERR_DEBUG_FILE environment variable is set (and the process is not
2886 setuid) the debugging messages may be redirected to a file.
2888 Change all of the e2fsprogs programs to use the newer add_error_table()
2889 and remove_error_table() interfaces instead of the much older
2890 initialize_*_error_table() function.
2892 Add TDB support into the ext2fs library. This allows us to have a
2893 guaranteed library we can count on always being present so we can
2894 store data in an on-disk database.
2896 Add support for using TDB to store the icount data, so we don't run out
2897 of memory when checking really large filesystems.
2899 Change the regression test suite so that it skips empty test directories.
2901 Define the l_i_iversion field in ext2_inode. The l_i_version field is
2902 now defined from the old l_i_reserved1 field in the ext2 inode. This
2903 field will be used to store high 32 bits of the 64-bit inode version
2906 Add Makefile production rule for e2fsprogs.spec in case it gets
2909 Add new function profile_get_uint() to allow for a clean way to fetch
2910 unsigned integers from the context.
2912 Add test to make sure the ext2 superblock structure is 1024 bytes.
2914 Fix typo in name of f_dup4 regression test
2916 Add new function blkid_gc_cache() which performs a garbage collection
2917 pass on the /etc/blkid.tab file.
2919 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2920 general, only e2fsck (after the filesystem is clean), tune2fs, and
2921 resize2fs should change the backup superblocks by default. Most
2922 callers of ext2fs_open() should not be touching any superblock fields
2923 which require the backups to be touched.
2925 Add new function to libext2fs, ext2fs_default_journal_size(), which
2926 returns the default journal size.
2929 E2fsprogs 1.39 (May 29, 2006)
2930 =============================
2932 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2933 between 2**31 and 2**32 blocks.
2935 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2936 configure the filesystem features, blocksize, and inode_ratio for
2937 different filesystem types.
2939 Mke2fs will now create filesystems hash trees and on-line resizing
2940 enabled by default, based on the new /etc/mke2fs.conf file.
2942 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2943 filesystem device node in exclusive mode to prevent accidents by
2944 system administrators. In the case of resize2fs and mke2fs, it will
2945 only use exclusive mode if the filesystem is not mounted.
2947 Fixed a bug in mke2fs which caused it to to fail when creating the
2948 resize inode for large filesystems. (Addresses Debian Bug #346580)
2950 When allocating space for the RAID filesystems with the stride
2951 parameter, mke2fs will now place each portion of the group's inode
2952 table right up after the superblock (if present) in order to minimize
2953 fragmentation of the freespace.
2955 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2956 efficiently by writing the inode and block bitmaps in one pass, thus
2957 reducing the number of disk seeks required.
2959 Add support for on-line resizing to resize2fs.
2961 Fix blkid library so that logic to determine whether or not a device's
2962 cached information in /etc/blkid.tab needs to be verified or not
2963 doesn't get confused by a system clock which is insane (for example,
2964 if the battery is dead on a Macintosh running PPC Linux. (Addresses
2965 Red Hat Bug: #182188)
2967 The blkid library will now store the UUID of the external journal used
2968 by ext3 filesystems, so that in the future, the userspace mount binary
2969 can use this to find the location of the external journal and pass
2970 this information to the kernel.
2972 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2973 control how various options should be handled. See the e2fsck.conf
2974 man page for more details. (Addresses Debian Bug: #150295)
2976 E2fsck now prints an explanatory message when delaying a filesystem
2977 check when the system is running on battery. (Addresses Debian Bug:
2980 E2fsck will detect if the superblock's last mount field or last write
2981 field is in the future, and offer to fix if so. (Addresses Debian Bug
2982 #327580) These problems will be fixed automatically in preen mode
2983 since Debian's boot sequence bogusly doesn't set the time correctly
2984 until potentially very late in the bootup process, and this can cause
2985 false positives which will cause users' systems to fail to boot.
2986 (Addresses Debian Bugs #343662 and #343645)
2988 E2fsck now checks to see if the superblock hint for the location of
2989 the external journal is incorrect, and if so, offer to update it.
2990 (Addresses Debian Bug: #355644)
2992 Fix e2fsck from segfaulting on disconnected inodes that contain one or
2993 more extended attributes. (Addresses Debian Bug: #316736, #318463)
2995 E2fsck will stop and print a warning if the user tries running a
2996 read/write badblocks test on a read-only mounted root filesystem.
2998 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2999 C. Thompson for pointing these out; they were originally found using
3002 When resizing a file containing a filesystem, resize2fs will expand or
3003 truncate a file as necessary. (Addresses Debian Bug: #271607)
3005 Resize2fs will now automatically determine the RAID stride parameter that
3006 had been used to create the filesystem, and use that for newly created
3007 block groups. The RAID stride parameter may also be manually specified
3008 on the command line using the new -S option to resize2fs.
3010 Fix mke2fs so that it correctly creates external journals on
3011 big-endian machines (such as a S/390).
3013 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3014 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
3015 Chambraud for pointing this out.)
3017 Dumpe2fs will now print the size of the journal (if present).
3019 Fix debugfs's set_inode_field command so it can properly set the frag,
3020 fsize, uid_high, gid_high, and author fields in the inode instead of
3021 silently failing, and so that setting the i_size actually sets i_size
3024 Add a new debugfs command, set_current_time, which sets fs->now so
3025 that regression test suites can repeatedly modify the filesystem's
3028 Fix a bug in debugfs's icheck which would incorrectly report the owner
3029 of an extended attribute block.
3031 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3032 print a usage message when an illegal option character is given.
3034 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3035 so it won't core dump. (Addresses SourceForge bug #1424311)
3037 Fix mklost+found so that it creates a full-sized directory on
3038 filesystems with larger block sizes.
3040 Fix a file descriptor leak in blkid library.
3042 Fix a display bug in "badblocks -sv" so that the done message properly
3043 clears the block number at the end of the test. (Addresses Debian Bug
3046 Allow fractional percentages to the -m option in mke2fs and tune2fs
3047 (Addresses Debian Bug: #80205)
3049 Use fstat/fstat64 in getsize.c if the the target is a regular file,
3050 instead of attempting to do a binary search. Fix some fd leaks in
3053 Add support for device mapper library to the blkid library to ensure
3054 that the "best" (i.e., leaf) device is probed by the blkid library.
3056 Fix the blkid library so that it notices when an ext2 filesystem is
3059 Improve the blkid's library VFAT/FAT detection; it now understands
3060 labels stored in the root directory, and is more paranoid about
3061 checking the FAT superblock values.
3063 Fixed a fd leak in the uuid library which was causing problems for the
3064 LVM tools. (Addresses Debian Bug: #345832)
3066 Add support for the reiser4 and software suspend partitions to the
3067 blkid library. Also add support for extract the label from iso9660
3070 Fix a compile_et bug which miscount the number of error messages if
3071 continuations are used in the .et file.
3073 Add extra sanity checks to protect users from unusual cirucmstances
3074 where /etc/mtab may not be sane, by checking to see if the device is
3075 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
3078 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
3079 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
3081 Fix use-after-free bug in e2fsck when finishing up the use of the
3082 e2fsck context structure.
3084 Fixed spelling mistakes, typos, and otherwise clarified man pages and
3085 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,
3086 #312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394,

3090 details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
3091 #310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,
3098 Update config.guess and config.sub to latest version (2006-02-23) from
3101 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
3102 Bugs: #360661, #360317)
3104 Fixed the Makefile so that they work correctly on newer versions of
3105 GNU make (i.e., 3.81).
3107 Add valgrind support to the regression test suites, and eliminate
3108 false positives from valgrind.
3110 Add a regression test suite for the blkid library.
3112 Fix a fencepost error in resize2fs caught by valgrind.
3114 Fix compiler warnings about missing memcpy prototypes.
3116 We no longer have the sparc assembly code in the header file any more,
3117 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
3118 break compiles on the sparc architectures when using gcc.
3120 In the libext2fs library, add the new field fs->now which if non-zero
3121 is used instead of the system time when setting various filesystem
3122 fields (last modified time, last write time, etc.)
3124 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3125 ext2fs.h which is needed since the inline functions use memcpy().
3126 (Addresses Sourceforge Bug #1251062)
3128 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3129 the build system when building files in the util directory which are
3130 needed during the build process. This avoids potential problems when
3131 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3132 are not recognized as valid by the host compiler. (Addresses
3133 Sourceforge Bug #1261547)
3135 Clean up the blkid library by making the superblock and generic i/o
3136 functions to be more generic. Clean up interface to the probe
3137 function, and fix memory leak. Finallly, remove an unneeded reference
3138 to probe.h in the lib/blkid/resolve.c
3140 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3141 of invalid block #'s.
3143 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3144 indicate that the the function read/writes the memory location.
3146 Fix various gcc -Wall complaints.
3148 Add a dependency to make sure that the subdirectories are created
3149 before creating all of the object files, in order to address parallel
3150 build problem in the library Makefiles. (Addresses Sourceforge Bug:
3153 Add $(LDFLAGS) to the command line argument when generating an ELF or
3154 Solaris shared library, to allow cross-compile and other builds that
3155 might need to specify -L paths to needed libraries. (Addresses
3156 Sourceforge Bug #1261549)
3158 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3159 intended for testing purposes. It allows an ext2/ext3 developer to
3160 create very large filesystems using sparse files where most of the
3161 block groups are not initialized and so do not require much disk
3162 space. Eventually it could be used as a way of speeding up mke2fs and
3163 e2fsck for large filesystem, but that would be best done by adding an
3164 RO_COMPAT extension to the filesystem to allow the inode table to be
3165 lazily initialized on a per-block basis, instead of being entirely
3166 initialized or entirely unused on a per-blockgroup basis.
3168 Fix backwards compatibility so e2fsprogs will better compile on Linux
3171 Make test scripts more robust against locale-related environment variables
3173 Fix type warning problem with sizeof() in ext2fs_open2().
3175 Fix type warning problem with time_t in debugfs.
3178 E2fsprogs 1.38 (June 30, 2005)
3179 ==============================
3181 Fix blkid's test programs (built with "make check") compile correctly
3182 even without "configure --enable-blkid-debug".
3184 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3185 type aliasing rules on newer gcc compilers. (Addresses Red Hat
3188 Fix com_err library to make it more compatible with recent changes
3189 made to the com_err library in MIT Kerberos V5 version 1.4.
3190 (Addresses Sourcefroge Bug #1150146)
3192 General cleanup of messages printed by e2fsprogs programs for grammar,
3193 consistency, and to make life easier for translators. Fixed a few
3194 strings containing English that had not been marked as needing
3195 translations. Removed strings that do not need to be translated, to
3196 make life easier for translators.
3198 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3199 test to see if a device appears to be in use instead of just relying
3200 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
3202 Fix portability problem in the filefrag program affecting platforms
3203 where the size of an integer is smaller than the size of a long.
3204 (Addresses Debian Bug #309655)
3206 Mke2fs will now use a larger journal by default for filesystems
3207 greater than 4GB. (128 MB instead of 32MB).
3209 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3210 unless forced. This is to avoid signed vs. unsigned kernel bugs in
3211 block numbers that still need to be fixed.
3213 The blkid program has a new option which will more efficiently search
3214 for device when it is known (or expected) that only one matching
3215 device will be found in the system, such as when doing a lookup by
3218 Debian's e2fsprogs-specific initrd fragment will avoid including
3219 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3220 and LD_LIBRARY_PATH, and filtering out libraries found in
3221 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
3223 Fixed a potential portability issue in the blkid programs for
3224 architectures where the char type is unsigned. (Addresses Sourceforge
3227 Fix a bug in filefrag so that it doesn't falsely count an extra
3228 discontinuity when the first block found is an indirect block.
3229 (Addresses Debian Bug #307607).
3231 Fix blkid's recognition of cramfs filesystems, and enhance it to be
3232 able to handle cramfs labels.
3234 Fix debugfs's stat command to not core dump when a filesystem is not
3237 Fix e2fsck's handling of error conditions caused by the resize inode
3238 claiming blocks that are also used by other inodes, a filesystem
3239 corruption which was commonly caused by a bug in Fedora Core 3's
3242 Fixed bug in filefrag which caused it to fail on non-ext2/3
3243 filesystems. (Addresses Debian Bug: #303509)
3245 If the superblock last mount time indicates that the system clock may
3246 not be accurate, then e2fsck will omit checking inodes' deletion time
3247 field for indications of a potential corrupted orphaned inode list.
3248 (Previously e2fsck only ommited these LOW_DTIME checks when the
3249 superblock's last write time looked insane.)
3251 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
3252 (Addresses Debian bug #302200)
3254 Make the blkid library more paranoid about being run from setgid
3255 programs, and to use __secure_getenv() from libc if it is available.
3257 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3258 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
3259 and Sourceforge Bug: #1189803)
3261 Updated and fixed translations.
3263 Fixed various Debian packaging issues --- see debian/changelog for
3269 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3270 changed to take an unsigned int for the bit number. Negative bit
3271 numbers were never allowed (and didn't make any sense), so this should
3272 be a safe change. This is needed to allow safe use of block numbers
3273 greater than or equal to 2**31.
3275 The compile_et program will avoid recreating generated foo_err.c and
3276 foo_err.h files if no changes are necessary. The compile_et program
3277 will also atomically replace these files to avoid a potential parallel
3278 build race problem on SMP systems. (Addresses Sourceforge Bug:
3281 Added a new function to the blkid library, blkid_probe_all_new(),
3282 which only probes newly added disk devices, and change
3283 blkid_find_dev_with_tag() to use this function so that when a
3284 requested tag is not found, devices that were previously not checked
3285 are searched before searching all devices in the system.
3287 Added new functions to the blkid library, blkid_dev_set_search() and
3288 blkid_dev_has_tag().
3290 E2fsck's problem strings can now use @m and @n as abbrevations for
3291 "multiply-claimed" and "invalid", respectively.
3293 The e2fsprog.pot file now has an explanation of how the @-expansion
3294 and %-expansion works, and strings in e2fsck/problem.c which contain @
3295 characters now have comments in e2fsprogs.pot with the @-expansion to
3296 make life easier for translators.
3298 Fixed missing return values in the ext2fs library which could cause it
3299 to return random garbage in certain error conditions.
3301 Allow the current time to be overriden via the E2FSCK_TIME environment
3302 variable for use in regression tests.
3304 The test scrpit driver program now exits with a non-zero status if
3305 there any of its test that it ran failed.
3307 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
3310 Fixed "make check" so that it compiles correctly even when e2fsprogs'
3311 header files have not be installed in the system include directories.
3312 (Addresses Sourceforge Bug: #1180572)
3314 Fixed gcc -Wall nits.
3317 E2fsprogs 1.37 (March 21, 2005)
3318 ===============================
3320 Add support for checking the validity of Extended Attributes stored in
3323 Add support for dumping the contents of large inodes to debugfs,
3324 including the extended attributes stored in inodes.
3326 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3327 when we create a new inode we make sure that the extra information in
3328 the inode (any extra fields in a large inode and any ea-in-inode
3329 information) is initialized correctly. This can take place when
3330 mke2fs creates the root and lost+found directory, when e2fsck creates
3331 a new root inode or a new lost+found directory, and when the user uses
3332 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3333 create inode could inherit garbage (or old EA information) from a
3334 previously deleted inode.
3336 Fixed a bug in e2fsck so it would notice if a file with an extended
3337 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3340 Added support to filefrag to detect files which are using the new
3341 experimental file extents format, and use the non-ext2 algorithm in
3342 that case. Fixed a bug to avoid reporting a false discontinuity if
3343 there is one or more unallocated blocks at the beginning of a file.
3345 Duplicated a check for noticing whether or not the number of blocks
3346 (given a certain blocksize) is greater than 2**32 when the
3347 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3348 allows mke2fs to automatically use a larger blocksize when creating a
3349 filesystem on a very large device when run on systems that do not
3350 support BLKGETSIZE64.
3352 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3353 build system had been switched to treat the .gmo files as shipped
3354 files (for backwards compatibility with systems that have older GNU
3355 I18N tools installed), but the gen_tarball.in script was still
3356 removing the .gmo files from the official source distribution.
3358 Fixed various Debian packaging issues --- see debian/changelog for
3359 details. (Addresses Debian Bugs ##296769, #299341)
3364 Added new functions to the e2p library which convert between a string
3365 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3366 make the generated binaries more compact.
3368 Fixed a compile-time error on Darwin systems.
3370 Cleaned up the lib/ext2fs Makefile slightly.
3373 E2fsprogs 1.36 (February 4, 2005)
3374 =================================
3376 All of the patches that were applied to Fedore Core 3's
3377 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3378 lot of bug fixes first. Users of Fedora Core 3 are strongly
3379 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3381 Add support for filesystem with the online resizing via resize inode
3382 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3383 patches also didn't bother to do any consistency checking on the
3384 resize inode, or add any tests to the regression test suite. The "-R
3385 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3386 being listed in mke2fs's usage message. All of these shortcomings
3387 have been corrected.
3389 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3390 program. In order to do this, the user must run the commands:
3392 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3393 e2fsck -f /dev/hdXXX
3395 Optionally, the ext2prepare command can be used to re-enable online
3396 resizing after the filesystem has been fixed.
3398 The fsck program will now accept an optional filedescriptor argument
3399 to the -C option. (The Fedora version of this patch would sometimes
3400 cause fsck to ignore a parameter on fsck's command line in some rare
3403 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3406 Make sure resize2fs releases the blocks belonging to the old inode
3407 table blocks when moving the inode table. (Addresses Debian Bug:
3410 Skip the r_resize_inode test if resize2fs is not compiled (due to
3411 configure --disable-resizer)
3413 E2fsck now checks the summary filesystem accounting information, and
3414 if any of the information is obviously wrong, it will force a full
3415 filesystem check. (Addresses Debian Bug #291571)
3417 Fix e2fsck to not complain when the resize_inode feature is enabled,
3418 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3421 Fix e2fsck to note delete symlinks that contain an extended attribute
3422 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3425 Add new utility program, copy_sparse.c, which is very useful
3426 for dealing with large sparse files (such as e2image files).
3428 Add support for jnl_blocks[] for debugfs's set_super_value.
3430 Fix filefrag so that it works correctly with sparse files.
3432 Filefrag -v will print first and last blocks.
3434 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3437 Add mke2fs support so that it can support filesystems larger than 4TB
3438 automatically, by retrying with a 4k blocksize if the device size is
3439 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3442 Change blkid to test for NTFS first because Windows sometimes doesn't
3443 clear enough of the parition to confuse the probing routines into
3444 thinking the old filesystem type is still valid. (Addresses Debian
3447 Add support for swap partition label and uuid's in the blkid library.
3449 Add support to the blkid library to recognize Oracle ASM volumes.
3451 Make blkid -t display all devices that match the specified criteria,
3452 not just the first one, and work more consistently when the blkid
3453 cache file is not available or set to /dev/null. (Addresses Debian
3454 Bug #290530 and #292425)
3456 Badblocks will now correctly display block numbers greater than
3457 999,999,999 in its progress display.
3459 The tune2fs program will not allow the user from setting a ridiculous
3460 number of reserved blocks which would cause e2fsck to assume the
3461 superblock was corrupt. E2fsck's standards for what is a ridiculous
3462 number of reserved block has also been relaxed to 50% of the blocks in
3465 The blkid library will return vfat in preference to msdos, and ext3 in
3466 preference to ext2 (if the journalling flag is set) so that mount will
3467 do the right thing. (Addresses Debian bug #287455)
3469 Mke2fs will now use the -E option for extended options; the old -R
3470 (raid options) option is still accepted for backwards compatibility.
3471 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3473 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3474 (via "32m" or "4g" on the command line) if the user finds this more
3475 convenient than specifying a block count.
3477 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3478 cache conherency problem.
3480 Debugfs now supports a new command, set_inode_field, which allows a
3481 user to manually set a specific inode field more conveniently, as well
3482 as set entries in the indirect block map.
3484 Debugfs's set_super_value command has been enhanced so that the user
3485 can set most superblock fields, including the date/time fields and
3486 some of the more newsly added superblock fields.
3488 E2fsprogs programs now accept an offset to be passed to the file
3489 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3491 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3492 support on the x86 doesn't exist for now, but it can be useful on
3493 other architectures with page sizes greater than 4k. There are 2.6
3494 kernel patches out there which enable this, but they are of this
3495 writing still experimental.
3497 The e2image command now takes the -s option which will scramble
3498 directory entries for raw image files.
3500 Fix a file descriptor leak in the filefrag program.
3502 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3505 Fix bug in debugfs where kill_file would lead to errors when deleting
3506 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3508 Fix bug in the blkid library when detecting the ocfs1 filesystem
3510 Remove obsolete EVMS 1.x and a.out DLL support.
3512 E2fsck will attempt to recover from a journal containing illegal blocks.
3514 Fixed two potential ordering constraint problems in e2fsck which might
3515 cause the filesystem to be corrupted if e2fsck is interrupted during a
3516 (extremely narrow) race window. Thanks to Junfeng Yang from the
3517 Stanford Metacompilation group for pointing this out.
3519 Fixed bug in e2fsck where it would not accurately detect whether or
3520 not the system is running on adaptor if the ACPI device representing
3521 the AC adapter didn't correspond to the what was used on IBM
3524 Change e2fsck to accept directories greater than 32MB.
3526 Fix e2fsck so that a checkinterval of zero disables a time-based check
3529 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3530 to the PAGER environment variable. (Addresses Debian Bug #239547)
3532 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3535 The debugfs program will set the filetype information when creating a
3538 Add debugfs -d option to use a separate source of data blocks when
3539 reading from an e2image file.
3541 Add e2image -I option which allows the e2image metadata to be
3542 installed into a filesystem.
3544 Fixed bug in the badblocks program which caused "done" to always
3545 appear in english even when a translation was available. (Addresses
3548 The blkid program has a new option -o which controls the output format
3549 of the blkid program; this is makes blkid more convenient to use in
3552 Fix a minor bug in uuid library, which was not using the full 14 bits
3553 of clock sequence when generating UUID's.
3555 Fix a Y8.8888K problem in the uuid library.
3557 Logsave now creates a new session id for itself to avoid getting
3558 killed by init whan transitioning between init levels.
3560 Change the licensing of the UUID library to be the 3-clause BSD-style
3561 license; this allows Apple to use the uuid library in Darwin.
3563 Add ocfs and ocfs2 probe support into the blkid library.
3565 Fix a memory and file descriptor leak in the blkid library.
3567 The blkid library will revalidate the device if the system time is
3568 earlier than last verification time of the device, since that
3569 indicates that the system time is probably nottrustworthy.
3571 The blkid library will override the default location of the blkid.tab
3572 file by the BLKID_FILE environment variable, if it is available.
3574 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3576 Add various portability fixes for lame new versions of glibc, Darwin
3577 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3578 Bugs #239934, #264630, #269044, #255589, #289133)
3580 Add support for Windows 9x/NT under Cygwin.
3582 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3583 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3585 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3587 Update the rpm spec files so that it works better with Fedora core 2
3590 Fixed various Debian packaging issues (see debian/changelog). In
3591 particular, fixed the Debian initrd scripts. (#241183, #248050,
3598 Fixed various gcc -Wall warnings.
3600 The uuid library now has new functions uuid_unparse_upper() and
3601 uuid_unparse_lower() which forces the case of the hex digits to be
3602 upper case, or lower case.
3604 The build process has been speeded up by enhancing the subst program
3605 to update the modtime on the generated files even when the generated
3606 file hasn't changed.
3608 The uuid library now uses C99 stdint.h types instead of custom types.
3610 Updated config.guess and config.sub with newer versions from the FSF.
3612 Removed out of date .cvsignore files from the source distribution.
3614 The ext2fs_unlink() function will return an error if both the name and
3615 inode number are unspecified, to avoid doing something surprising
3616 (such as unconditionally deleting the first directory entry).
3617 Directory entries are now deleted by coalescing them with the previous
3618 directory entry if possible, to avoid directory fragmentation. This
3619 is not an issue with the e2fsprogs suite, but may be a problem for
3620 some of the users of libext2fs, such as e2tools.
3622 Add support for version numbers of the form "1.36-rc1".
3624 Fix build of mke2fs.static.
3626 Add basic ext2fs library support for large (EA in inode) inodes.
3628 The test_io mechanism can now abort after n reads or writes to a
3629 particular block. The block is specified by TEST_IO_BLOCK environment
3630 variable, and the read/write count by the TEST_IO_READ_ABORT and
3631 TEST_IO_WRITE_ABORT environment variables. The block data is now only
3632 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3634 UUID_DEFINE() in the uuid library now creates a static variable, with
3635 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3636 be used in header files.
3638 Add support for the install-strip and install-shlibs-strip targets, as
3639 suggested by the GNU coding guielines. "make install" no longer
3640 strips the binaries which are installed.
3642 Remove support for the --enable-old-bitops configure option which was
3643 only for very old sparc systems.
3645 Remove support for --enable-clear-htree; this was only needed during
3646 the early development of the htree patch.
3648 Use Linux-kernel-style makefile output so it is easier to see compiler
3651 Update gettext files to version 0.14.1.
3653 Update to use autoconf 2.5x.
3655 Improved support for compiling e2fsprogs under dietlibc.
3657 Make e2fsprogs portable to Solaris and FreeBSD systems.
3659 Add blkid_verify(), blkid_get_library_version(), and
3660 blkid_parse_version_string() functions to the blkid library.
3662 Add pkg-config files for e2fsprogs's libraries.
3664 Fix "make uninstall" to so that it removes everything that is installed.
3666 Add a configure --enable-maintainer-mode option which enables the
3667 makefile rules to rebuild the configure script from configure.in, and
3668 to reubuild the .gmo files in po directory.
3670 Drop the sparc assembly bitwise operations; it's less efficient
3671 than the GCC 3.4 compile code and triggers compiler warnings on
3672 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
3673 (Addresses Debian Bug #232326)
3676 E2fsprogs 1.35 (February 28, 2004)
3677 ==================================
3679 E2fsck has a new -k option, which in conjunction with the -c options,
3680 preserves the existing badblocks list.
3682 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3684 E2fsprogs will now deal correctly with symlinks that contain
3685 extended attribute information, which can be created using SE Linux.
3686 (Addresses Debian Bug #232328)
3688 Remove a double longjump into an invalid stack frame bug in e2fsck.
3689 (This was during an abort sequence, which normally worked on Linux and
3690 caused a core dump on other operating systems.)
3692 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3693 (the NLS library will replace "" with the .po header information).
3695 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3696 dump due to a division by zero error. (Addresses Debian bug #207082)
3698 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3699 when reconnecting a directory requires creating a lost+found
3700 directory. (Addresses Debian bug #219640).
3702 Fixed a bug where e2fsck would bomb out if a journal needed to be
3703 replayed when using an alternate superblock.
3705 E2fsck will give an extra grace period before actually forcing a check
3706 if the laptop is running on battery. The next time fsck runs while
3707 the system is on the AC mains, or after the grace period is exceeded,
3708 the filesystem will be checked. (Addresses Debian bug #205177)
3710 E2fsck will inform the user when there are 5 or fewer mounts before a
3711 filesystem check will be forced. (Addresses Debian bug #157194)
3713 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3714 We now correctly handle the case where there is an overlap between a
3715 block group descriptor or a superblock and a bad block indirect block.
3716 In the case where the indirect block is corrupted, we now suggest
3719 Fix byte swap bugs in e2fsck that caused the journal backup location
3720 in the superblock and symlinks created by SE Linux to be cleared
3721 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
3723 E2fsck -c now replaces the current list of bad blocks with the ones
3726 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3727 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3729 Fix a potential bug in e2fsck which could cause it to core dump when
3730 trying to print the location of the backup superblock.
3732 Protect against a potential core dump in e2fsck when printing a
3733 message about backup superblocks.
3735 Add support for backing up the journal inode location in the
3736 superblock. E2fsck will automatically save the journal information in
3737 the superblock if it is not there already, and will use it if the
3738 journal inode appears to be corrupted. ext2fs_add_journal_inode()
3739 will also save the backup information, so that new filesystems created
3740 by mke2fs and filesystems that have journals added via tune2fs will
3741 also have journal location written to the superblock as well.
3742 Debugfs's logdump command has been enhanced so that it can use the
3743 journal information in the superblock.
3745 E2fsck will now update all superblocks when moving the journal inode.
3747 Shrink the size of the e2fsck executable by moving some initialized
3748 variables to the BSS segment.
3750 E2fsck will avoid printing the ^A and ^B characters which bracket the
3751 progress bar when stdout and stdin are a tty device instead of a pipe
3752 to another program. (Addresses Debian bug #204137)
3754 Debugfs's mkdir command will automatically expand the directory if
3755 necessary. (Addresses Debian Bug: #217892)
3757 Fixed a bug in debugfs so that copying a file from /dev/null uses the
3758 correct mode bits. (Addresses Debian Bug: #217456)
3760 If the environment variables DEBUFS_PAGER and PAGER are not set,
3761 debugfs now searches for the appropriate pager to use, beginning with
3762 /usr/bin/pager, and then falling back to 'more' and 'less'.
3763 (Addresses Debian bug #221977)
3765 Debugfs will now support 2.6 device numbers where the major or minor
3766 number may be larger than 255. (Addresses Sourceforge bug #865289)
3768 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
3770 Chattr now stops processing options when it sees '--'. (Addresses
3773 Fix regression tests so they work correctly when e2fsprogs is compiled
3774 with configure --disable-htree.
3776 Fix bug in uuid library when there is no network card and the library
3777 is generating a time-based uuid. The random MAC address was not
3778 correctly generated to be a multicast address.
3780 Add compile_et extensions from Heimdall that were missed the first time
3783 Fix bug in badblocks when using O_DIRECT; we need to make sure that
3784 we're reading from an offset which is page aligned. For read-only and
3785 read-write tests, we try to recover after an error so that we can
3786 continue reading on page-aligned boundaries. (Addresses Debian Bug
3789 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
3792 Updated and clarified various man pages. (Addresses Debian Bug
3793 #206845, #222606, #214920, #232406)
3795 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
3797 Fixed various Debian packaging issues (see debian/changelog).
3802 Fixed a build problem so that e2fsprogs would compile with the
3803 --enable-profile option to configure selected. (Addresses Sourceforge
3806 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
3807 Bugzilla Bug #112448)
3809 Centralize code which calculates the location of the superblock
3810 and block group descriptors so that it is in a single library routine.
3812 Added two new functions, ext2fs_file_open2() and
3813 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3815 Fix compile_et to output the correct prototype for
3816 initialize_xxx_err_table_r() in the header file. (Addresses Debian
3819 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3821 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3822 present. This is for when we try stuffing an int into void * pointer.
3824 Fix type-punning which can cause gcc 3.x to miscompile code by getting
3825 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3826 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3827 **'. The EVMS code uses an ugly union approach since we don't want to
3828 modify the EVMS interfaces.
3830 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3831 aid build process on systems can use invoke GNU make as "gmake".
3833 Added regression testing for mke2fs.
3835 Fixed gcc -Wall nitpicks.
3837 Fixed various compiler warnings.
3839 Add portability fixes for FreeBSD and for using fsctl under Darwin to
3840 support ext2 ioctl's.
3843 E2fsprogs 1.34 (July 25, 2003)
3844 ===============================
3846 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3847 a tight loop while waiting for a child fsck to exit in some cases.
3848 This burns CPU times which slows down the low-level filesystem check.
3850 Added code to mke2fs to assure that the default block size for a
3851 filesystem is at least as big as the sector size of the device, if it
3854 Changed mke2fs and resize2fs to round the default size of a filesystem
3855 to be an even multiple of the VM pagesize in order to avoid a Linux
3856 kernel bug introduced when the storage of the buffer cache was moved
3857 into the page cache.
3859 Mke2fs will warn the user when creating a filesystem with journaling
3860 and a blocksize greater than 4096. (Addresses Debian bug #193773)
3862 Fixed a bug in resize2fs which caused it to fail on filesystems with a
3863 non-empty bad block list. Resize2fs now discards any blocks on the
3864 badblock list which are no longer part of the filesystem as the result
3865 of a filesystem shrink. (Note: this means that shrinking and then
3866 enlarging a filesystem is no longer a reversible operation;
3867 information about bad blocks in the part of the filesystem which is to
3868 be chopped off will be lost.)
3870 Changed resize2fs so the user can use prefixes to specify the units of
3871 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3872 and to make the error and informational messages explicitly display
3873 the blocksize used by the filesystem, in order to avoid confusion.
3874 (Addresses Debian bug: #189814)
3876 Added a new debugfs command, dump_unused, which dumps the contents of
3877 all unused blocks to stdout. (Useful as an emergency try-to-find
3878 deleted data command.)
3880 Added a new debugfs command, imap, which prints the location of a
3881 specified inode in the inode table.
3883 Fixed a bug in the badblocks program which caused it to use one bit of
3884 randomness in its non-destructive read/write test, instead of using a
3885 full 8 bits of randomness.
3887 Added a new option (-t) to badblocks, which allows the user to control
3888 the test pattern(s) used when checking a disk.
3890 The blkid probe function now more correctly detects UDF filesystems.
3892 Fixed a bug in the blkid library which caused it to not update its
3893 cache if a filesystem changes from having a label to not having a
3896 Fixed a bug in the blkid library wihch could avoid an infinite loop
3897 in blkid_find_dev_with_tag() if /proc is not mounted and there the
3898 /etc/blkid.tab file has not yet been created.
3900 Fixed the badblocks program so that the destructive read/write test
3901 honors the -c option, and to use O_DIRECT when possible to avoid
3902 thrashing the system block buffer cache.
3904 Fixed various NLS issues.
3905 - Added Czech and Swedish translations
3906 - Removed testing NYC translation
3907 - Fixed NLS support for message abbrevations in e2fsck
3908 - Remove de-utf.po, since we shouldn't have two versions using different
3910 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3911 simplify the statistics reporting in e2fsck.
3913 Changed configure.in so that its defaults for *BSD systems no longer
3914 build an fsck wrapper, and not to install in /usr/local by default.
3916 Fixed some minor spelling errors/typo's in e2fsck and the configure
3919 Fixed various Debian packaging issues (see debian/changelog).
3921 Updated and clarified man pages. (Addresses Debian Bug #195616)
3926 Fix gcc -Wall nitpicks.
3928 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3929 NLS support by default. (Added partial workaround for gettext/Darwin
3930 incompatibility problems.)
3932 Added full MIT KRB5 and Himdall compaibility support to the com_err
3933 library and the compile_et program. (Addresses Debian bug #191900)
3935 Added the blkid_known_fstype() function to the blkid library, which
3936 returns true if it is passed a filesystem type which is recognized by
3937 the blkid probing functions.
3939 Improved the documentation for the blkid library.
3941 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3942 returns the hardware sector size of a device, if it is available.
3944 Added a dependency in the blkid library's .so file to the uuid
3945 library, since the former uses the latter. (Addresses Debian bug
3948 Added --with-diet-libc and --disable-evms to the configure script.
3950 Fixed a minor memory leak in the badblocks program.
3952 Fixed a portability problem in tune2fs --- not all systems have strptime().
3954 Fixed a portability problem in debugfs with the use of getopt() more
3955 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3958 Add support Windows support to ext2fs_get_device_size().
3960 Added (normally disabled) debugging code to the Unix I/O manager which
3961 causes it to disable all userspace caching if the NO_IO_CACHE is
3964 Changed the test I/O manager so it can always be linked into e2fsck,
3965 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3966 configure script. The test I/O manager will only print any debugging
3967 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3968 variables are set, which specifies which I/O operations are logged and
3969 a block number to watch, respectively. The log messages are sent to
3970 stderr by default, unless a filename is specified via the
3971 TEST_IO_LOGFILE environment variable.
3974 E2fsprogs 1.33 (April 21, 2003)
3975 ===============================
3977 Added a new utility program, logsave, which captures the output of a
3978 command in a log file, even if the containing directory hasn't been
3979 mounted yet (in which case the it saves the output in memory until it
3980 can write out the logfile). This is useful for capturing the
3981 output of fsck during the boot sequence.
3983 Fixed some portability problems that were causing problems under
3984 the Cygwin32 environment.
3986 Mke2fs now interprets a negative number to the -b option as a minimum
3989 Fixed a bug in mke2fs which was incorrectly checking the argument to
3990 the -g option if the default block size was used. (Addresses Debian
3993 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3994 it can not find filesystem checkers for jfs, reseirfs, and xfs.
3996 E2fsck now updates the global free block and inode counters from the
3997 block group specific counters quietly. This is needed for an
3998 experimental patch which eliminates locking the entire filesystem when
3999 allocating blocks or inodes; if the filesystem is not unmounted
4000 cleanly, the global counts may not be accurate.
4002 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4003 2.0 is not yet supported; this only pulled in the bug fixes: fixed
4004 possible hangs caused by bugs in calling waitpid, and not setting the
4005 pipe to non-blocking mode; also fixed a file descriptor leak; made
4006 sure all functions call log entry/exit functions.)
4008 Badblocks now flushes its output file as bad blocks are discovered.
4010 The uuid library is now more paranoid about assuming the correctness
4011 of the /dev/random device; it mixes in a stream of bytes from
4012 random/srandom, just in case.
4014 Update Debian files to reflect the fact that I am now the Debian
4015 maintainer of e2fsprogs. Other various Debian-specific packaging
4018 Move the source tarball generation functions from the top-level
4019 makefile to the util/gen-tarball script.
4021 Updated the Turkish .po translation file.
4023 Added Heimdal and MIT krb5 extensions to the com_err library to make
4024 it more compatible with com_err libraries from those distributions.
4026 Changed dumpe2fs to always display the superblock fields relating to
4027 the journalling and/or directory indexing feature even if those
4028 features are not enabled.
4030 Updated and clarify copyright statement vis-a-vis alpha releases of
4033 The ss library will now try to dynamically link to the readline
4034 library and use it if it is present in the system. This means that
4035 the debugfs program now has line editing and history features. The
4036 SS_READLINE_PATH environment variable is used to find a readline or
4037 readline-compatible library.
4039 E2fsck now finds most duplicate filenames (all when rebuilding all
4040 directories via the -D option) and offers to delete or rename
4041 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
4043 Fix bug in e2image. When writing out a raw image file, include data
4044 blocks from symlinks that do not store the symlink within the inode.
4046 Fix bug in resize2fs which incorrectly moved the block and inode
4047 bitmaps for sparse superblock filesystems and incorrectly marked
4048 blocks as in use. (Addresses Debian bug #174766)
4050 Added a new shared library, the blkid library, which efficiently
4051 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4052 and UUID filesystem specifiers without needing to search all of the
4053 devices in the system. Instead, the device is looked up in a cache
4054 file, and then verified to make sure the blkid cache is correct.
4056 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4057 the device name, using the blkid library. (Addresses Debian bugs
4060 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4061 used for spaces in device labels.
4063 Removed 32-bit limitations for debugfs's dump command.
4065 If the user specifies a large number of inodes, Mke2fs will
4066 automatically adjust the number of blocks per group to find a valid
4067 set of filesystem parameters.
4069 Add workaround to detect broken MD devices where when some of the
4070 underlying devices are marked read-only, writes to the MD device are
4071 silently dropped. E2fsck will detect if there is an attempt to run
4072 the journal twice, and abort with an error if this is the case.
4073 (Addresses IBM Bugzilla bug #1226)
4075 E2fsck will print an error if more than one of the -p/-a, -n or -y
4076 options are specified.
4078 E2fsck will fix HTREE corruptions in preen mode, without stopping the
4079 boot process. This is needed because the 2.4 ext2 filesystem
4080 accidentally had the INDEX_FL backwards compatibility code removed.
4082 Mke2fs no longer creates filesystems with the dir_index flag set by
4083 default; the user has to specifically request it.
4085 Update and clarified various man pages. (Addresses Debian bugs
4086 #173612, #175233, #175113, and #170497, #185945, #188318)
4088 Created man page for the mk_cmds program (from the libss library).
4093 Fix various gcc -Wall nits.
4095 Fixed a lot of portability problems that caused e2fsprogs not to build
4096 successfully under Solaris and Apple/Darwin.
4098 Fixed a Makefile dependency to allow building e2fsprogs using parallel
4101 Changes to create a subset distribution which consists only of the
4102 et, ss, uuid, and blkid libraries. The configure script and top-level
4103 makefile were changed to support working with a subset distribution.
4105 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4106 actually used, and might people who are looking for
4107 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4109 Updated debian files to fix a number of Lintian warnings.
4111 Updated config.guess and config.sub with newer versions from the FSF.
4113 Removed unnecessary libraries from being linked into the fsck, lsattr,
4114 chattr, and blkid executables.
4116 E2fsprogs 1.32 (Nomvember 9, 2002)
4117 ==================================
4119 Fixed a bug in the Unix I/O routines which caused needless writebacks
4120 of clean blocks from the unix_io cache (they were erroneously marked
4121 as being dirty, so they were getting written back to disk before
4122 getting evicted from the disk cache). This was harmless, but it
4123 significantly slowed down e2fsck.
4125 Made some other minor optimizations to the Unix I/O routines to save a
4126 small amount of CPU time.
4128 Updated internationalization files.
4131 E2fsprogs 1.31 (Nomvember 8, 2002)
4132 ==================================
4134 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
4135 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
4136 handling for child process that die unexpectly. Add a hack to force
4137 mkfs to create filesystems that won't cause problems with hardware
4138 that has 2k or 4k minimum blocksize requirements. Read from child
4139 processes in non-blocking mode, so that the GUI continues to update.
4141 Fix e2fsck so that it returns the appropriate exit code when the root
4142 filesystem has been changed, so that system's rc scripts will be told that
4143 the system needs to be rebooted.
4145 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4146 was set, some of the descriptor blocks that should have been written
4147 out were getting skipped.
4149 Changed e2fsck to force out changes to the backup copies of the
4150 superblock and block group descriptors when important changes are made
4151 to those data structures.
4153 Fix a bug where e2fsck could erroneously mark a filesystem as being
4154 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
4155 introduced in e2fsprogs 1.28.)
4157 If journal debuging is enabled using --enable-jbd-debug, the debugging
4158 level is now set via the E2FSCK_JBD_DEBUG environment variable.
4160 If byteswapping support is disabled using configure --disable-swapfs,
4161 skip the tests which depend on byte-swapping, so that "make check"
4164 Lshattr will now display the indexed directory flag. Also, some of
4165 the more esoteric compression flags are supressed unless compression
4166 support has been enabled.
4171 E2fsprogs 1.30 (October 31, 2002)
4172 =================================
4174 When resizing a filesystem, and inodes need to moved, resize2fs will
4175 update the inode's ctime field, and the mtime field of the containing
4176 directories, so that incremental backups using dump/restore will work
4179 In order to avoid spurious errors, e2fsck wil check the last
4180 superblock write time to determine whether or not it can safely use
4181 the LOW_DTIME checks to determine if there are inodes on the orphan
4182 inode linked list that had somehow gotten disconnected. (Addresses
4183 Sourceforge bug #620980)
4185 Partition in /proc/partitions that being with the string "lvm" are
4186 considered real partitions even if they do not end with a number.
4188 Fixed a bug in the the uuid generation function, where if /dev/urandom
4189 is not present, but /dev/random is, and there isn't sufficient
4190 entropy, the get_random_byte function could spin a loop forever.
4192 E2fsck, mke2fs, etc. will now reliably notice when image files are
4193 mounted using the loopback interface. (Addresses Sourceforge bug
4196 When flushing buffers (as is done by badblocks, for example) check to
4197 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4198 FDFLUSH ioctl which causes the MD device driver which causes confusing
4199 syslog messages about obselete ioctl messages. (Addresses Sourceforge
4202 Debugfs's write command now checks to see if the destination filename
4203 exists before creating it. (Addresses Sourceforge bug #478195.)
4205 When installing man pages, search for compressed man pages using all
4206 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4208 Fixed a bug in fsck where multiple filesystems specified on the
4209 command were not being checked in parallel due to a logic bug
4210 introduced to support the FSCK_MAX_INST environment variable.
4212 We have added a new superblock field, s_mkfs_time, which indicates
4213 when a filesystem was created. It is set via mke2fs, and printed out
4214 by dumpe2fs, but is not actually touched by the kernel.
4216 Dumpe2fs has been made more robust by not aborting if there is an
4217 error reading the block/inode bitmaps; instead it will still print out
4218 the location of the block/inode bitmaps and inode table.
4220 Add support for the an alternative block group descriptor layout which
4221 allows for on-line resizing without needing to prepare the filesystem
4222 in advance. (This is the incomat feature flag meta_bg.)
4224 Add support for storing default mount options in the superblock, so
4225 that the filesystem can be mounted with specific mount options without
4226 needing to specify them on the mount command line or in the /etc/fstab
4229 Add support for a new inode flag, which is to be used for indicating
4230 the top of directory hierarchies for the Orlov block allocator.
4232 Fix e2fsck so that if it creates the lost+found directory, it does so
4233 with the more apporpriate permissions of 0700. Also change
4234 mklost+found so that it also creates the directory 0700.
4236 Fixed format bug in e2fsck if NLS is in use.
4238 Add a German translation for e2fsprogs's NLS support.
4240 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4241 the beginning of the inode table. This won't matter much, since if
4242 there is a bad block at the beginning of the inode table, the root
4243 directory won't be available. But at least e2fsck won't crash in this
4246 Fixed endian problems in the htree code for e2fsck and debugfs.
4248 When byte-swapping a filesystem on a PPC architecture, byte-swap the
4249 bitmaps since the historical big-endian ext2 variant had byte-swapped
4250 bitmaps, and the ext2fs library assumes this. This fixes the
4251 regression test suite on PPC machines.
4253 Fix e2image so that it handles a bad block in the inode table
4256 E2fsck now uses a more sophisticated algorithm to salvage corrupted
4257 directories that recovers more information in the corrupted directory
4260 E2fsck now performs additional consistency checks on indexed (HTREE)
4263 Fix bug where efsck might get confused about whether a completely
4264 empty directory block is an empty leaf block or an interior htree
4265 node. This could cause e2fsck to get confused into think that a valid
4266 indexed directory was corrupted.
4268 E2fsck no longer creates an empty directory entry at the end of a
4269 directory block when optimizing a directory. This would cause some
4270 earlier versions of the dxdir kernel code to corrupt the directory
4271 when attempting to split a node containing an empty directory entry.
4273 E2fsck could sometimes in rare circumstances leave the indexed flag
4274 set after a small directory was optimized by compressing it instead of
4275 indexing it. (This should never happen in real life, since
4276 directories that small wouldn't have been indexed, but better safe
4279 E2fsck now only updates the master superblock in all cases. This
4280 slightly shortens its run time.
4282 Ext2ed can deal with directory entries of length 0; previously it
4283 would get stuck in an infinite loop.
4285 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4286 specifiers. (Sourceforge patch #613447)
4288 Badblocks will now work correctly on read-only devices such as
4289 CD-ROM's. (Sourceforge patch #600451)
4291 Updated and clarified man pages. (Addresses Debian bug #167108)
4294 E2fsprogs 1.29 (September 24, 2002)
4295 ===================================
4297 Fixed a bug in e2fsck which could corrupt a directory when optimizing
4298 it (via the -D option) or rebuiliding the hash tree index with a 1 in
4299 512 probability, due to a fence post error.
4301 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4304 Mke2fs now enables the directory indexing flag by default. (Since
4305 this is a compatible feature flag, it's safe to do so.)
4307 Tune2fs will support setting the directory indexing feature flag. It
4308 will automatically set up the default hash algorithm and hash seed
4309 fields in the superblock.
4311 If the bone-headed user enters the root filesystem twice in
4312 /etc/fstab, the -R option which skips the root filesystem will skip
4313 all of them. (Addresses Debian bug #159423). Note! This is not a
4314 precedent for dealing intelligently with any other kind of doubled
4315 entry in /etc/fstab!
4321 Removed perror declaration in lib/et/internal.h. All modern systems
4322 can be expected to define perror() these days. Besides, the lib/et
4323 code wasn't using perror at all anyway. :-)
4326 E2fsprogs 1.28 (August 31, 2002)
4327 ================================
4329 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4330 for setting the htree flag is not included yet, although it can be
4331 manually turned on via the debugfs program.
4333 Clarified e2fsck error message which is printed when it cannot find
4334 sufficient contiguous block when relcating filesystem metadata.
4336 Added support for building an EVMS plugin module for ext2/3. This
4337 module is substantially the same as the EVMS module shipping with EVMS
4338 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4339 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4340 if the configure --enable-old-evms flag is given.
4342 Fsck will search through EVMS volumes when trying to resolve
4343 filesystem specifications such as LABEL=xxx or UUID=xxx.
4345 Added a new utility program, /sbin/findfs, which will return
4346 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4349 Update and clarified various man pages. (addresses Debian Bug #145044,
4350 #146437, #131350, #151990, #144621, #141938)
4352 If there are no filesystems specified on fsck's command line, fsck now
4353 treat that as if the -As options were given. Previously it would
4354 simply do nothing. (Addresses Debian Bug #153102)
4356 Mke2fs no longer treats a failure to be able to clear the MD signature
4357 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4360 The e2p library functions (which are used by lsattr and chattr) now
4361 double check to make sure the file is a regular file or directory
4362 before attempting to use the ext2 ioctls. Some device drivers
4363 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4364 (Addresses Debian Bug #152029).
4366 The extended attribute handling has been updated to correspond with
4367 the latest V2 bestbits ACL code.
4369 Fixed bug in e2fsck which caused it to not clear the dtime field when
4370 processing truncated inodes on the orphan list. This could cause data
4371 loss(!) if a filesystem is rebooted before a truncate has been
4374 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4375 algorithms. This makes e2fsck much faster in the case of severely
4376 corrupted filesystems where a large number of blocks are claimed by a
4377 large number of inodes. (Thanks to the 2.5 IDE device driver for
4378 inspiring this work.)
4380 Resize2fs has been significantly sped up when shrinking and expanding
4381 a filesystem by a very small number of blocks (for example, when EVMS
4382 is converting a partition to be an EVMS legacy volume).
4384 Added a new option to e2fsck, -D, which will optimize or compress all
4385 of the directories in the filesystem.
4387 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4388 properly clean up and only exit at safe points. Fsck will pass
4389 SIGINT/SIGTERM to its child processes, and wait until they have all
4390 exited before it exits.
4392 The uuid parsing code in the uuid library now properly complains when
4393 an illegally formated uuid is presented to it. (Addresses Debian bug
4396 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4397 and 2.4.17, since the workaround can cause problems when using a 2.4
4398 kernel with an old version of glibc built with the 2.2 headers.
4400 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4401 superblock used by other filesystems. (Addresses Debian bug #147256.)
4403 Added support for the synchronous directory feature written by Andrew
4406 The debugfs program can delete directories using the rmdir command.
4408 Add support for 8k and 16k filesystems (for systems with page sizes
4409 that are greater or equal to 8k or 16k, respectively). Note that
4410 these filesystems can not be mounted on x86 systems, or other systems
4411 with only 4k page sizes, due to limitations in the current Linux VM
4414 Resize2fs requires that the filesystem state be valid and have no
4415 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4416 required that the last fsck time be greater than the last mount time.)
4418 Configure now defaults the man pages directory to /usr/share/man on
4421 E2fsck now offers to truncate inodes which contain too many blocks (so
4422 that i_blocks would overflow. Also fixed handling of large sparse
4425 E2fsck now more completely checks for symlink validity, including
4426 requiring NULL termination and length checks.
4428 E2fsck will offer to try forcing a disk write to remap a bad block
4429 after finding a read error when reading a filesystem metadata block.
4431 Fixed a bug in debugfs which caused the -b and -s options to crash
4432 debugfs, as well as breaking the testb, setb, and clearb functions.
4434 Added a bmap command to debugfs which calculates the logical to
4435 physical block mapping for a particular inode.
4437 Fixed a bug in code which checked to see if a device was mounted which
4438 sometimes (rarely) failed in the case of a plain file.
4440 Fixed a bug in resize2fs where when it reported an error, it would
4441 print a message erroneously indicating that the filesystem had been
4442 resized before it aborted.
4444 When resizing a plain file which is smaller than the requested size,
4445 resize2fs will attempt to extended the file so that programs like
4446 e2fsck will not complain that the file is too small.
4448 Resize2fs will print the actual new size of the filesystem when it is
4451 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4452 information on big-endian systems.
4458 Fixed collisions with C++ reserved words.
4460 Added portability fixes for building e2fsprogs on the HURD and AIX.
4462 Added the ext2ed program for creation of test cases. (ext2ed has many
4463 limitations and bugs which make it unsuitable for production use.)
4465 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4466 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4467 name_len field is byte swampped on big-endian machines, since in the
4468 V2 structure, name_len is a char field which is doesn't need to be
4469 byte swapped --- except if an old-style kernel had byte-swapped the
4470 name_len field as part of the V1 structure.
4473 E2fsprogs 1.27 (March 8, 2002)
4474 ==============================
4476 The warning messages for mke2fs now go to standard error.
4478 Fixed to make sure "make check" runs all of the test programs with
4479 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4481 The mke2fs program checks the boot sector for the BSD disk label, and
4482 avoids erasing it if it is there.
4484 Fixed a bug in e2fsck which caused it to core dump if the journal
4485 inode was missing when it was supposed to be there.
4487 E2fsck now prints ranges in pass 5 when printing deltas for the block
4490 Debugfs's "ls -l" command now will print out the file type information
4491 in the directory entry.
4493 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4494 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4496 Debugfs can now examine the experimental directory indexing
4499 Fixed bug in debugfs which caused it to core dump if modify_inode is
4500 called without an open filesystem.
4502 The debugfs lsdel command now runs its output through a pager first.
4504 When installing manual pages, remove the compressed manual pages first.
4506 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4508 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4509 actually broke things on mips32, sparc32, and Alpha platforms.
4511 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4512 (which is required by the newer libintl libraries).
4517 Fixed various gcc -Wall complaints.
4519 Fixed a few memory leaks in the e2fsck journaling code, and in the
4520 ismounted code checking for a swap device.
4522 Add new inode I/O abstraction interface which exports an inode as
4525 Exported ext2_file_flush as a public interface.
4527 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4529 Lots of small random portability fixes to make e2fsprogs build under
4530 AIX --- even without the 5L compatibility toolkit, and even using the
4531 uber-crippled AIX native C compiler.
4534 E2fsprogs 1.26 (February 3, 2002)
4535 =================================
4537 Dumpe2fs will keep going now if the bad block inode can't be read.
4538 (Previously it stopped with a fatal error.)
4540 E2fsck will now give an opportunity to run the journal even if the
4541 recovery flag is not set. This is the default behaviour if e2fsck is
4542 using a backup superblock, since the needs_recovery flag will never be
4543 set in the backup superblock copies.
4545 E2fsck now automatically finds the backup superblock/group descriptors
4546 even when the primary superblock is completely destroyed for 2k and 4k
4547 filesystems. (Previously it just guessed/assumed that we were dealing
4548 with a 1k filesystem in that case, and users had to manually specify
4549 the backup superblock number.)
4551 Fixed a bug in e2fsck where it dereferences a null pointer when there
4552 is a problem opening a filesystem in preen mode.
4554 E2fsck now handles external journals correctly; previously it trashed
4555 the external journal device if the journal needed to be replayed.
4557 Work around ulimit incompatibility problem caused by recent 2.4
4558 kernels; the unix IO module will automatically try to set any resource
4559 limits to be infinite on startup.
4561 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4562 bitmap if it wasn't present and the blocksize was 2k or 4k.
4563 (Addresses Debian Bug #116975)
4565 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4566 clearing the new V2 fields if they do not make sense or if the ext3
4567 superblock is version 1 superblock.
4569 E2fsck will automatically relocate the ext3 journal from a visible
4570 file (i.e., /.journal) to an hidden inode if the filesystem has been
4571 opened read/write. This allows the users to add a journal while the
4572 filesystem is mounted, but the next time the system is rebooted, the
4573 journal file will disappear. This avoids problems with backups,
4574 stupid operators with superuser bits, etc.
4576 Fix a bug in fsck where it would not support a filesystem type of
4577 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4579 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4580 automatically identify reiserfs filesystems.
4582 The number of processes spawned by fsck can now be limited using the
4583 FSCK_MAX_INST environment variable.
4585 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4586 should be searched for UUID and label information.
4588 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4589 limit if at all possible, when opening a block device. (The filesize
4590 limit shouldn't be applied against writes to a block device.)
4592 In mke2fs and e2fsck, specifying the -c option twice will now do
4593 a read/write test on the disk. Update the man pages to encourage
4594 using the -c option, and to discouraging running badblocks separately,
4595 since users tend to forget to set the blocksize when running
4598 Mke2fs now automatically clears the immutable attribute on a
4599 pre-existing .journal file left over from a previous failed attempt to
4600 add a journal to an alreadyy-mounted filesystem.
4602 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4605 Mke2fs now creates the lost+found directory with permissions of 0700,
4606 so that files that had previously lived in protected directory are
4607 safe if they get dropped in lost+found and the system administrator
4608 doesn't deal with immediately. (Addresses Debian #bug 118443)
4610 Mke2fs and e2fsck (and all programs that use the
4611 ext2fs_check_if_mounted function) will now properly identify that a
4612 device is mounted, even in cases where devfs has confused things with
4613 multiple devices names with the same identity, or if a dim-witted
4614 system administrator has done something stupid like creating device
4615 file aliases in their home directory. Also now checks for swap devices
4616 by using /proc/swaps. (Addresses Debian bug #106622)
4618 Added a new option (-T) to tune2fs which sets the time a filesystem
4621 Speed up e2image when creating sparse raw image files by optimizing
4622 away excess lseek() system calls.
4624 Fix support of large (> 2GB) files when used as a filesystem in
4625 mke2fs, tune2fs, debugfs, and findsuper.
4627 Debugfs's stat and icheck commands now properly deals with large (>
4630 Debugfs's set_super_value command now prints out the list of valid
4631 superblock fields which can be set using the command.
4633 Debugfs's rm and kill_file command now updates the superblock free block
4634 and inode counts, thus keeping the filesystem consistent.
4636 Debugfs's lsdel command now takes an optional argument which allows
4637 the user to only see the most recently deleted files.
4639 A new command (undel) was added to debugfs which automates
4640 undeleting a deleted inode and linking it back to a directory.
4642 Debugfs's ls command now takes a new option, -d, which lists
4643 deleted directory entries.
4645 Debugfs's testb, freeb, setb, and find_free_block commands now take an
4646 optional count argument.
4648 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4649 be used to signal that a particular inode should not be eligible for
4650 tail-merging --- this is needed for programs like LILO.
4652 The findsuper (an unreleased, uninstalled utility program) has been
4653 improved to add extra validity checks and to add a progress meter.
4654 (It is still an unsupported program; the officially supported way to
4655 recover from a trashed partition table is to use gpart; findsuper is
4656 for wizards only. :-)
4658 Debugfs was fixed to compile with "configure --disable-swapfs".
4660 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
4662 Added new translation file for Turkish.
4667 Fix general gcc -Wall complaints.
4669 E2fsprogs (mostly) works with the dietlibc.
4671 The programming texinfo file has been expanded to include description
4672 of additional libext2fs functions. (Still not compeltely done, but a
4673 lot of the more important functions have been documented.)
4675 Added a umask structure to struct_ext2_filsys, which currently only
4676 modifies the behaviour of ext2fs_mkdir(), but if we add any file
4677 creation functions to libext2fs, we should also make sure they respect
4680 The build-rpm script was fixed to be a bit more safe.
4682 The tests' Makefile now has a way of automating test case creation
4683 for e2fsck, using "make testnew".
4685 Created a new function, ext2fs_dir_iterate2 which passes more
4686 information to the callback function (identical to the one used by
4687 ext2fs_dblist_dir_iterate). The directory iterator functions take a
4688 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4689 directory entries. If the directory entry is deleted, the callback
4690 function will be called with the entry paraemter set to
4691 DIRENT_DELETED_FILE.
4693 Added new functions, ext2fs_inode_alloc_stats and
4694 ext2fs_block_alloc_stats, which takes updates block/inode allocation
4695 statistics in the bitmaps, block group descriptors, and superblock
4696 when inodes or blocks are allocated or deallocated.
4699 E2fsprogs 1.25 (September 20, 2001)
4700 ===================================
4702 This is primarily a bug-fix release; no new features were added, but
4703 there are a number of embarassing bug fixes and cleanups applied.
4705 Fix a bug mke2fs which causes stack garbage to be written to disk when
4706 zapping disk sectors. (This bug could cause mke2fs to core dump for
4707 some kernels, I suspect with security enhancement patches.)
4709 Remove unneeded #include of <linux/config.h> which was breaking
4710 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
4712 Updated tune2fs man page to reflect the fact that adding or removing a
4713 journal doesn't require running e2fsck.
4715 Remove use of AC_REQUIRE from autoconf which had been used to prevent
4716 AC_CANONICAL_HOST from being called twice; unfortunately this causes
4717 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4718 used outside of autoconf macros. Fortunately, it doesn't seem to be
4719 necessary any more, anyway.
4721 E2fsck will now not fall back to an alternate superblock if the user
4722 specifies the superblock location explicitly on the command-line.
4723 This allows easier recovery from a situation where the primary
4724 superblock and block groups are slightly corrupted, but the backup
4725 superblocks are completely broken.
4727 Fix problem which caused compile_et and mk_cmds to blow up if
4728 e2fsprogs was in a directory with a pathname that contained spaces.
4730 We are now more paranoid about checking the entry in /etc/mtab to make
4731 sure the filesystem is really mounted, since some broken distributions
4732 (read: Slackware) don't initialize /etc/mtab before checking non-root
4733 filesystems. (Slackware also doesn't check the root filesystem
4734 separately, and reboot if the root filesystem had changes applied to
4735 it, which is dangerous and broken, but there's nothing I can do about
4738 Make UUID library C++ friendly by adding appropriate extern "C"
4739 declarations and using const in the function declarations.
4741 Fix up the com_err texinfo file so that it can product a valid info
4742 file (previously, it could only be used to generate paper
4743 documentation using texinfo.tex).
4746 E2fsprogs 1.24a (September 2, 2001)
4747 ===================================
4749 Fix brown-paper bug in mke2fs which caused it to segfault when
4750 printing the version string.
4753 E2fsprogs 1.24 (August 30, 2001)
4754 ================================
4756 Revert the BLKGETSIZE64 support, since for some distributions, this
4757 ioctl has been used by an unofficial kernel patch to update the last
4758 sector on the disk, and this was causing disk corruption problems as a
4761 Mke2fs is now more careful about zapping swap space signatures and
4762 other filesystem/raid superblock magic values so that programs like
4763 mount who try to use hueristics to determine the filesystem type of a
4764 partition are less likely to be confused.
4766 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4767 regular file (since Andreas Dilger's on-line resizing tools will set
4770 Fixed some minor texinfo, man pages nits for spelling errors,
4771 texinfo warnings, etc. (Addresses Debian bug #110621.)
4773 E2fsprogs program no longer print the filesystem version number
4774 (i.e. 0.5b), since it only confuses people and doesn't serve any real
4777 E2fsck will once again compile under libc5, since it will supply its
4778 own version of strnlen if necesssary.
4780 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4781 when specifying the external journal device. tune2fs will also search
4782 devices looking for the externla journal debice when removing.
4784 E2fsprogs 1.23 (August 15, 2001)
4785 ================================
4787 Add initial support for extended attributes (EA); e2fsck will
4788 correctly handle a filesystem with EA's and check the EA blocks for
4791 E2fsck's symlink sanity checking has been cleaned up. It now checks
4792 the i_size value of fast symlinks, and checks for immutable flags
4793 being set of symlinks, etc.
4795 E2fsck now offers to clear inodes which are special files that have a
4796 non-zero i_blocks or i_size field. (The i_size field check was in the
4797 previous version of the code, but due to a bug it didn't offer to
4798 clear the inode unless i_size and i_size_high were both non-zero.)
4800 E2image can now create "raw" image files, which only contain the
4801 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4802 debugfs, etc., can be run directly on the raw image file.
4804 Add support for the 64-bit block device patches.
4806 Fixed bugs in creating external journals with a 1k blocksize.
4808 Add initial support for external journals (so long as the external
4809 journal only supports a single filesystem) in e2fsck.
4811 Remove requirement for needing to run fsck on a filesystem after
4812 removing a journal (either internal or external).
4814 The man pages now document how to create and manage external journals.
4816 Speed up the check of an ext3 filesystems by avoiding a needless flush
4817 of all of the superblock and block group descriptors.
4819 Speed up creating an internal journal using tune2fs in the case where
4820 the filesystem has a lot blocks already allocated.
4822 Tune2fs has been fixed to make sure that only error messages go to
4823 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4825 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4826 now not set the sparse_super feature. (Addresses Debian bug #108165)
4828 Add support in fsck for the filesystem type "auto".
4830 Fsck -A will not try to interpret device names for filesystems which
4831 have a pass number is 0. (Addresses Debian bug #106696).
4833 Fsck prints a warning message if now valid filesystems are passed to
4834 it. (Addresses Debian Bug #107458.)
4836 E2fsck now gives an explicit warning if there filesystem still has
4837 errors at the end of the run. (Addresses Debian bug #104502)
4839 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4840 reflects an error. E2fsck will also not run the orphan list if the
4841 filesystem contains errors, since the orphan list might be corrupted.
4843 E2fsck now prints the number of large files when given the -v option.
4845 Fixed minor memory leaks in e2fsck.
4847 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4850 E2fsprogs 1.22 (June 22, 2001)
4851 ==============================
4853 Fixed a bug in e2fsck's handling of orphan inodes which are special
4854 files (i.e., block/character device files, named FIFO's, etc.).
4856 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4857 tune2fs to fail at adding a journal to a mounted filesystem.
4859 Fixed a few big-endian bugs in e2fsprogs
4860 * The directory block functions were accidentally reporting
4861 some directories as corrupted when they weren't.
4862 * If e2fsprogs is compiled --disable-swapfs, the C language
4863 equivalents weren't being included for big-endian platforms.
4864 (Fixes Debian bug #101686).
4866 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4871 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4872 ioctls, and allow them to be defined for non-i386 platforms.
4874 The uuid.h header file is now protected against multiple inclusions.
4876 E2fsprogs is now being developed using BitKeeper. Changed the test
4877 scripts to deal with BK's stripping CR characgters from text files,
4878 and changed the top-level Makefile.in to avoid including BitKeeper
4879 files when generating the source tarball.
4882 E2fsprogs 1.21 (June 15, 2001)
4883 ==============================
4885 Added new configure flags which allow a subset e2fsprogs to be built;
4886 this is most useful for boot floopies, since the resulting shared
4887 libraries and programs are slimmed down by removing features that
4888 aren't necessary for a boot floppy. The new flags that were added
4889 are: --disable-swapfs, which removes support for byte swapping old
4890 legacy PPC/68k filesystems, --disable-debugfs, which removes support
4891 for debugfs from the libext2fs library, --disable-imager, which
4892 removes support for the e2image program, and --disable-resizer, which
4893 removes support for resize2fs.
4895 E2fsck now prints the number of mounts or days elapsed since the last
4896 check when e2fsck is forced to check an otherwise clean filesystem.
4898 Tune2fs now prints an informative message about how often a filesystem
4899 will be checked when adding a journal to the filesystem, to remind the
4900 user that he/she may want to adjust those parameters using tune2fs
4903 Worked around hurd brain-damage which causes e2fsck to sometimes
4904 believe a filesystem is the root filesystem based on device numbers
4905 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4908 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4909 erroneous error with the -F option was specified.
4911 Fixed a ext3 recovery bug in the revoke handling; synchronized with
4914 Fixed two bugs in e2fsck's handling of dup block handling, dealing
4915 with relatively uncommon edge cases: a directory with an indirect
4916 block which is claimed by another file, and when the last inode in the
4917 filesystem has blocks claimed by another file.
4919 E2fsck now checks to see if the i_size field of a fast symlink is too
4920 big, and offers to clear the symlink if so.
4922 E2fsck now checks to see if i_size_high of special files is non-zero,
4923 and offers to clear i_size_high.
4925 Fix e2fsck's handling of incompatible journal flags so that the user
4926 has chance to abort, and then has the option to clear out the journal
4927 entirely. (Addresses Debian bug #98527.)
4929 Fixed a bug in fsck which could cause it to core dump if a mix of
4930 standard and non-standard device names are used in /etc/fstab.
4931 (Debian bug #100559)
4933 Fixed a bug in debugfs which caused read errors when copying a file to
4936 The debugfs set_super_value command can now modify the s_lastcheck field.
4938 Fixed a bug in lsattr and chattr which was accidentally introduced in
4939 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
4940 directories correctly because the change modified the layout of struct
4941 dirent to be incompatible with the libe2p shared library.
4943 Cleaned up the mke2fs manual page and included a discussion about why
4944 it's good to periodically check the filesystem even when journaling is
4950 Fix general gcc -Wall complaints.
4952 The types needed by the ext2 header files are now provided by
4953 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4955 Integers are now preferred to longs when trying to find a 32-bit type
4956 in ext2_types.h. Also, if linux/types.h has already been defined,
4957 don't try to redefine the types.
4959 Fixed make depend script so that it automatically corrects the
4960 pathname cleanups performed by make -M, so I don't have to fix them up
4963 Fixed the d_loaddump test case to be more robust, and not depend on
4966 Removed debugfs's dependence on pread(), which was accidentally
4967 intrudced in e2fsprogs 1.20
4969 Fixed a performance bug in the libext2fs's icount routine; the size
4970 estimate of the icount array was incorrectly being calculated.
4972 Removed use of the badblocks compatibility functions in the e2fsprogs
4975 Added paranoia code which protects against strange cases where /etc
4976 isn't on the root filesystem, or if /etc/mtab doesn't exist.
4978 The header file ext2_types.h is now installed.
4980 Autoconf is used to determine when we are on big-endian machines,
4981 instead of doing run-time tests, to save a few bytes of code.
4983 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4984 functions are no longer inline functions, which saves space and
4985 doesn't really cost any real performance.
4987 The ext2fs library no longer depends on the e2p library. (What need
4988 there was of it --- namely, fsetflags, was coded in-line).
4990 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4991 when the user is stupid and tries compiling the package using "make
4994 Miscellaneous code cleanups:
4995 * Added missing files from Makefile.in's SRCS file, so that
4996 their dependencies would be properly calculated.
4997 * Removed redundant code
4998 * Fixed comments in code
4999 * Removed no-longer unneeded argsused #pragma.
5002 E2fsprogs 1.20 (May 20, 2001)
5003 =============================
5005 Add support for replaying the ext3 journal purely in user mode,
5006 including handling the orphaned inode list. Used code contributed by
5007 Andreas Dilger, with bug fixes and the orphaned inode handling done
5010 The mke2fs and tune2fs programs can create or modify a filesystem to
5011 include an ext3 journal. Tune2fs also can be used to remove an ext3
5012 journal from a filesystem.
5014 E2fsck will now check for the existence of a linked list of orphan
5015 inodes in the superblock, and clear those inodes before starting the
5016 rest of the filesystem check (but after the journal playback).
5018 E2fsck now validates the file descriptor passed to the -C option,
5019 which saves against the completion bar getting written to an
5020 unexpected location, such as the disk being checked. (Debian
5021 bug/wishlist #55220)
5023 E2fsck will now bump the filesystem revision number from zero to one
5024 if any of the compatibility bits are set.
5026 Fixed a bug where a badly corrupted directory on a big endian system
5027 could cause e2fsck to die with a bus error. The
5028 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5029 the ext2 library now does alignment sanity checks on the rec_len field
5030 of the directory entry before using it.
5032 The ext2 library has been enhanced to make tune2fs safe to run on
5033 mounted filesystems. (Users could usually get away with using tune2fs
5034 on mounted filesystems before, but with the advent of ext3 and
5035 journaling, it became important to make tune2fs was *really* safe for
5036 use even when the filesystem being modified is mounted.) E2label is
5037 now implemented by tune2fs using an argv[0] dispatch, so that e2label
5038 is also now safe for use on mounted filesystems.
5040 Added a new program, e2image, which creates a backup of critical ext2
5041 filesystem data structures. The generated image file can be examined
5042 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
5043 the image file to help recover very badly damaged filesystems.
5045 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5046 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
5047 large file when deciding whether or not the filesystem has large files.
5049 Fixed lsattr and chattr so that they work correctly on large files.
5050 (Fixes Debian bug #72690.)
5052 Removed limitation in get_device_size() which imposed a one terrabyte
5053 filesystem limitation. (Most 2.2 kernels still have a signed int
5054 problem which cause 1 TB block device limitation. Fortunately, the
5055 kernel patches to fix this are much easier than fixing the 2TB
5056 limitation in the kernel. :-)
5058 A max_mount_count of zero is now treated as if no mount count were
5059 set. (Previously, no mount count was indicated by using -1, and a
5060 mount count of zero caused e2fsck to always be run.)
5062 Mke2fs supports two new filesystem types largefile and largefile4.
5064 Mke2fs now adds some randomness in s_max_mount_count so that multiple
5065 filesystems won't be all checked at the same time under normal
5068 Fixed bug in the progress bar printing code which could cause e2fsck
5069 to core dump on an illegal filesystem.
5071 Fixed bug in fsck which could allow more than one instance of e2fsck
5072 to be printing a progress bar. (Debian bug #65267)
5074 Fsck using a UUID or a LABEL specifier will work even if devfs is
5075 compiled into the kernel and not mounted. If the pathnames in
5076 /proc/partitions are incorrect, fsck will search /dev for the correct
5077 device (using the new ext2fs_find_block_device library function).
5078 Fsck now also checks the RAID devices first so that they are properly
5079 found when they are in use. Support has also been added to support
5080 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
5082 Fixed a bug in fsck which caused it not deal properly with 16
5083 byte long filesystem labels.
5085 Fsck's -t option has been made a lot more flexible. The semantics for
5086 what happens if a comma-separated list to fsck has been regularized,
5087 and it is now possible to filter what filesystems will get checked
5088 based what is in the filesystem's fstab entry's option field. (Debian
5091 The dumpe2fs program can now print out the group description
5092 information in hex, and also prints the location of the superblock and
5093 block group descriptor for those block groups that have them.
5095 Mke2fs now clears the ext2 superblock before it starts creating a
5096 filesystem, so that the superblock magic number is only written if the
5097 filesystem creation process successfully completes.
5099 The debugfs program's stat command now pretty-prints the blocks used
5100 by an inode so that it's more compact and informative.
5102 The debugfs stats command now uses the same libe2p code (which is used
5103 by dumpe2fs) to print the superblock header information. This is more
5104 complete, and it avoids a bit of code duplication.
5106 Added a new debugfs command, set_super_value (ssv) which allows the
5107 user to set arbitrary superblock fields.
5109 Debugfs was extended to support inode numbers in hex (by prefixing
5110 them with 0x), and so that modify_inode can set the inode generation
5111 number. Also, there is now a new function command called logdump
5112 which will dump an ext3 journal.
5114 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5117 Debugfs's dump command now stops immediately upon reporting a disk
5118 read error. (Fixed a bug in ext2fs_file_read library routine which
5119 caused debugfs not to stop.) (Debian bug #79163)
5121 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5122 checked before /etc/mtab is used, since /proc/mounts is more likely to
5125 Added portability fixes for Solaris and Linux/ia64.
5127 Various manual pages were clarified and cleaned up. (Fixed debian
5128 bugs #63442, #67446, and #87216)
5134 The e2fsck message printer now supports %Iu and %Ig, which will print
5135 out the inode's user and group owners, respectively.
5137 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5138 that no longer dependent on the system having the correct version of
5139 the kernel header files.
5141 Added a new function to libext2, ext2fs_find_block_device(), which
5142 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5143 device given its device number.
5145 Added a new function to libext2, ext2fs_sync_device, which centralizes
5146 all of the places which might try to use the BLKFLSBUF or FDFLUSH
5147 ioctls (and usually failing to define them since the system header
5148 files don't usually do this for us, and we're trying to avoid usage of
5149 kernel include files now).
5151 Added new utility programs in tests/progs: random_exercise and
5152 hold_inode. They aren't built by default; they're useful for
5153 exercising ext3 filesystem code.
5155 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5156 the filesystem close functions to only update the superblock, and to
5157 not touch the block group descriptors. Needed by tune2fs when
5158 modifying a mounted filesystem.
5160 Got rid of struct ext2fs_sb and replaced it with the standard struct
5161 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
5162 source (but not binary) compatibility of some users of the ext2
5163 library. Those applications should just simply do a global search and
5164 replace of struct ext2fs_sb with struct ext2_super_block, and include
5165 the new header file <ext2fs/ext2_fs.h> which defines it.
5167 The ino_t type has been renamed ext2_ino_t to protect applications
5168 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5169 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
5170 unexpected ABI change.
5172 The Makefiles have been reworked so that "make check" can be run from
5173 the top-level Makefile.
5175 Fix general gcc -Wall complaints and removed dead code.
5177 Remove use of NOARGS, because we assume everyone does ANSI C these
5180 Added build-rpm script from sct.
5182 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
5185 New function ext2fs_flush_icache which must be called if the
5186 application program modifies the inode table blocks without going
5187 through ext2fs_write_inode() interface.
5189 New ext2fs_check_mount_point() function, which will return the mount
5190 point of a device if mounted.
5192 The io_channel abstraction now has an optional interface,
5193 io_channel_write_range, which allows specific byte ranges to be
5196 The unix_io IO channel now supports write-through caching, so that
5197 journal creation is more efficient.
5199 Added x86 assembly language routines to support byte swapping, to
5200 reduce executable size.
5202 Fixed bug in the utility program subst so that it's possible to
5203 replace a substitution variable with a zero-length string.
5205 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5206 slipped into some of the problem number.
5208 E2fsprogs 1.19 (July 13, 2000)
5209 ==============================
5211 Release the resize2fs program since the timeout before it could
5212 be released under the GPL has finally expired.
5214 Add experimental support needed for the ext2 compression patches.
5215 This requires compiling e2fsprogs with the --enable-compression flag
5216 to the configure script.
5218 Added ext3 journalling support. E2fsck will run the journal (if
5219 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
5220 installed as a symlink to e2fsck. Fsck has been taught about ext3,
5221 and treats it the same as ext2 in terms of the progress bar logic.
5222 Dumpe2fs will display the superblock journaling information if the
5223 filesystem has a journal. The ext2 library will now permit opening an
5224 ext3 filesystem with the recovery flag set. This is necessary for
5225 on-line dump's to work correctly, but there may be issues with this
5226 working well since ext3 is much less agressive about syncing blocks to
5227 the filesystem, since they're safe on the journal.
5229 Tune2fs and e2fsck have been changed to allow the mount_count check to
5230 be disabled by setting max_mount_count to -1. (This was already
5231 supported by the kernel.)
5233 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5234 are used for ext3 as well.
5236 Added internationalization support for e2fsprogs; must be enabled
5237 by passing --enable-nls to configure.
5239 Always use the provided ext2fs header files to insulate ourselves from
5240 kernel version changes. Which include files are used by e2fsprogs
5241 have also been cleaned up to improve portability.
5243 Limit the number of times that e2fsck updates the progress bar so that
5244 people who are booting using a 9600 baud console don't get swampped by
5247 Improved the loop detection algorithm in e2sck's pass #3 so that it is
5248 much, much faster for large filesystems with a large number of
5251 The memory footprint for e2fsck is now slightly smaller than before.
5253 E2fsck now checks if special devices have a non-zero size, and offers
5254 to clear the size field if it finds such an inode.
5256 E2fsck now checks if special devices have the append-only flag set,
5257 and offers to clear the inode.
5259 E2fsck now properly handles some "should never fail" cases during a
5260 bitmap copy in pass5.
5262 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5264 E2fsck now calculates the correct location of the backup superblock in
5265 the case of filesystem blocksizes > 1k.
5267 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5268 which normally didn't cause problems under most filesystem parameters,
5269 but could cause a valid superblock to be rejected in extreme cases.
5270 Other checks for validating superblock values were made more
5273 Added non-destructive write testing to the badblocks program, courtesy
5274 of David Beattie. The badblocks also now has an option to input the
5275 current set of bad blocks, so that known bad blocks are skipped to
5276 speed up the badblocks test. There is also a persistent rescan
5277 feature which causes badblocks to run until it has completed some
5278 number of passes without discovering any new bad blocks.
5280 Badblocks now checks to see if the device is mounted and refuses to do
5281 the tests involving writing to the device if it is mounted. Also,
5282 badblocks now allows the number of blocks to be checked to be
5283 defaulted to the size of the partition.
5285 Fixed a bug in fsck which didn't allow non-root users to be able to
5286 check filesystems if there were any LABEL= or UUID= entries in
5289 The Hurd doesn't support the filetype filesystem feature. The mke2fs
5290 program now makes sure that for the Hurd, the filestype feature is
5291 turned off. E2fsck will check to see if the filetype feature is
5292 turned on for Hurd filesystems, and offer to turn off the feature.
5294 Mke2fs now has a safety check to make sure the number of blocks do not
5295 exceed 32 bits even on a 64 bit platform.
5297 Really fixed a bug in fsck to allow "fsck -As" to run interactive
5298 fsck's. (For those people who like to do interactive fsck's in the
5301 Debugfs has a few new features: the rdump command, which will do a
5302 recursive dump of a directory and all of its contents, and the lcd
5303 command which does a local chdir (much like the ftp command of the
5304 same name). In addition, the debugfs program and the open_filesystem
5305 command now takes three new options: -b and -s, which allows the
5306 blocksize and superblock location to be specified, and the -c option
5307 which is used in catastrophic situations where the block group
5308 descriptors are corrupt. If the -c option is specified, debugfs will
5309 skip trying to read in the block and inode bitmaps.
5311 Debufs's lsdel command was fixed to handle bad blocks in the inode
5314 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
5317 General improvements in error messages
5319 - Mke2fs prints a sane error message if the partition size is zero
5320 (usually because the partition table wasn't reread by the
5321 kernel due to the partition being busy), instead of "invalid
5322 argument passed to ext2 library while initializing superblock".
5324 - Fsck now prints more self-explanatory message if an invalid UUID=
5325 or LABEL= specification is passed to it.
5327 UUID library changed to use the LGPL.
5329 Fixed a bug in the UUID library where very rapid calls to the
5330 time-based UUID generator could cause duplicate UUID's to be returned.
5331 This was not a problem for e2fsprogs, but it could be a problem for
5332 other users of the library.
5334 Make the UUID library more robust in the face of missing or an
5335 improper /dev/urandom or /dev/random files.
5337 Added some random portability fixes for Solaris.
5339 Some minor man page updates.
5341 Fixed a memory leak in the ss library.
5347 We now try to use lseek64 and open64 from the LFS if possible.
5349 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5352 The mark and unmark bitmap functions now return the previous state of
5353 the bit that was being changed, which is useful for some speed
5356 The following functions have been added to enhance the badblocks list
5357 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5358 ext2fs_badblocks_equal.
5360 The ext2 header files now have the latest journalling fields to the
5363 The ext2fs_mkdir function in libext2fs now properly backs out of error
5364 conditions robustly.
5366 Cleaned up makefiles:
5367 - to cleanly compile with the -j flag.
5368 - so distclean removes all generated files.
5369 - so in case of an error while installing header files, the make aborts.
5371 Fix test_script so that it works correctly when compiling in the
5374 The random UUID generation routine has been made slightly better in
5375 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5376 is still not recommended if /dev/random doesn't exist, however; it's
5377 better to use the time/ethernet MAC address UUID in this case.)
5379 Clean up the build process so it's more friendly in case of missing
5382 The ext2fs header file can now be #include'd into C++ programs.
5384 The e2p.h header file is now installed.
5386 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5390 E2fsprogs 1.18 (November 10, 1999)
5391 ==================================
5393 Fix a core dumping bug in e2fsck if an imagic inode is present or
5394 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5395 has to restart pass 1 processing. E2fsck now closes the filesystem
5396 before freeing a large number of its data structures, so in the case
5397 of future memory faults, at least the fixed filesystem will be fully
5400 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5401 imagic inode, it will offer to clear the imagic flag.
5403 E2fsck will now offer to clear the immutable flag on special files
5404 (device/socket/fifos) when running it in non-preen mode.
5406 E2fsck will now set the filetype when creating /lost+found, and when
5407 connected orphaned inodes to /lost+found.
5409 Debugfs's ncheck and icheck commands now handles the case where there
5410 are bad blocks in the inode table without bombing out.
5412 The badblocks list processing code has been made more efficiently for
5413 appending a large number of (ordered) badblocks to the badblocks list.
5415 Some minor man page updates.
5417 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5418 mode, but some people like to do this in boot scripts for silly reasons).
5423 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5424 with the problem code convention.
5426 The badblocks list regression test program has been updated to work
5427 with previously made API name changes.
5429 The ext2fs_free() command now uses the new badblocks API to avoid
5430 using the compatibility layer.
5432 Added new regression test cases; the run_e2fsck test script now
5433 supports the ability for a test case to run a prepratory command
5434 before running e2fsck.
5436 E2fsprogs 1.17 (October 26, 1999)
5437 =================================
5439 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5442 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5443 thus potentially causing problems if a binary UUID contained a NULL
5446 E2fsck now uses stricter checks for directory entries in pass 2:
5447 zero-length filenames are not allowed; neither are 8 byte long
5450 The debugfs "dirty" command now clears the filesystem valid bit.
5451 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5452 bit in the in-core superblock image. The new functionality is more
5453 what the user expects, and is more useful.)
5455 Added a debugging hook to test parallel fsck; if the environment
5456 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5457 will be checked in parallel when they normally would not be.
5462 Fixed some #ifdef's for compilation under the Hurd OS.
5464 Fixed minor W2K compatibility problems.
5466 Fixed some miscellaneous GCC warnings.
5469 E2fsprogs 1.16 (October 22, 1999)
5470 =================================
5472 Fixed a race condition bug in fsck; when printing a progress bar, if
5473 checking multiple filesystems in parallel, it was possible for fsck to
5474 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5475 handler, which would cause it to terminate with a signal 10.
5477 E2fsck now properly handles filesystems that have the
5478 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5479 filesystem into using or not using FILETYPE feature.
5481 E2fsck now properly handles filesystems that have the IMAGIC feature
5482 turned on (this is used on Linux AFS servers).
5484 The mke2fs program now creates filesystems that have the filetype and
5485 sparse_superblock features enabled by default, unless it is run on a
5486 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5487 so there is now a new flag -O which allows the user to specify with
5488 which features she would like to create the filesystem; "mke2fs -O
5489 none" will create a filesystsem compatible with 2.0 kernels.
5491 The tune2fs program now has a -O option which allows the user to set
5492 and reset "safe" filesystem features. Currently, the only ones which
5493 allows to be modified are the filetype and sparse_superblock features.
5494 Note setting or clearing either feature will require running e2fsck on
5495 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5496 requires that there is enough free space on the filesystem for the
5497 extra superblocks which will be created by e2fsck.)
5499 Debugfs can now set and print filesystem features in the superblock
5500 using the "features" command. Dumpe2fs will print out the complete
5501 set of features when listing the superblock.
5503 Dumpe2fs has new options -f (force) and -h (header-only).
5505 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5506 message to come up. This could happen when decrementing or
5507 incrementing a link count could result in an overflow.
5509 Fixed a bug in e2fsck where the block count on the lost+found
5510 directory would not be properly incremented when the directory was
5511 expanded to the point where an indirect block needed to be allocated.
5513 E2fsck now makes some additional sanity checks on the superblock to
5514 avoid crashing or giving a memory allocation error if some of the
5515 values in the superblock are unresonable (but the superblock otherwise
5518 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5519 require two passes to completely fix the filesystem. This happened if
5520 an inode claimed blocks that was part of the filesystem metadata
5521 (typically, when garbage was written into an inode table or indirect
5522 block, since this kind of filesystem corruption normally doesn't
5525 On the Alpha, glibc declares st_flags although it isn't actually used;
5526 the configure script was improved to detect this case so that
5527 e2fsprogs can avoid using the non-functional stat field.
5529 The manual pages were updated to use a more consistent formatting
5530 style consistent with standard Unix man pages. Mke2fs's man page
5531 added documentation for a few previously undocumented options.
5533 Fixed minor display bugs in tune2fs and mke2fs.
5538 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5540 Added features to parse and print feature strings into the e2p library.
5541 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5543 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5544 whose directory entries contain proper filetype information if the
5545 filesystem supports it.
5547 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5548 the directory entry filetype information. This is used to set the
5549 directory entry filetype information if the filesystem supports it.
5551 Fixed a bug in ext2fs_expand_dir() where the block count in a
5552 directory's inode would not be properly incremented when the directory
5553 was expanded to the point where an indirect block needed to be
5557 E2fsprogs 1.15 (July 18, 1999)
5558 ==============================
5560 Add configuration checks so that e2fsprogs will compile cleanly on
5561 Linux 2.3 kernels that have renamed i_version to i_generation.
5563 E2fsck now prints a progress/completion bar (and not just a simple
5564 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5565 signal. Fsck will automatically manage the (potentially muliple)
5566 e2fsck processes to print completion bars if it is given a -C option,
5567 with the right thing happening if multiple filesystems are being
5568 checked in parallel.
5570 Mke2fs now has better automatic hueristics to determine the filesystem
5571 parameters to be used for a particular filesystem. Added a new option
5572 -T which allows the user to specify how the filesystem is to be used,
5573 which helps mke2fs do a better job selecting the filesystem parameters.
5575 Mke2fs now creates revision 1 filesystems by default, and with the
5576 sparse superblock feature enabled. The sparse superblock feature is
5577 not understood by Linux 2.0 kernels, so they will only allow read-only
5578 mounts of filesystems with this sparse superblocks.
5580 Fix bug where if /dev/null couldn't be opened (should never happen),
5581 e2fsck would hang in a tight loop.
5583 Make e2fsck handle the case where /lost+found isn't a directory.
5585 E2fsck now uses mallinfo if it exists to get accurate statistics about
5588 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5589 inode had any problems before connecting it to /lost+found.
5591 Add check to e2fsck so it makes sure that total number of inodes in
5592 the filesystem is a sane number.
5594 Fix fencepost error when clearing an the end of the block bitmap which
5595 caused the last block in the bitmap not to get cleared.
5597 Cleaned up a number of messages in e2fsck:
5598 * The message "Group's #'s copy of the group descriptor..."
5599 was fixed so that the correct number would be displayed.
5600 * Added missing space in the "disk write-protected" error messsage
5601 * Cleaned up the error message printed when a non-interactive
5602 e2fsck needs to abort a check because the filesystem
5603 appears to be mounted.
5605 Added a new command-line utility, uuidgen, which will create and print
5608 Make debugfs's icheck command more robust by checking to make sure an
5609 inode has valid blocks before interarting over the inode's blocks.
5611 UUID generation now uses a random-based scheme whenever possible to
5612 prevent potential privacy problems.
5614 Man pages for all of the UUID functions in the lirbary were added.
5616 Fixed bug in fsck so it won't coredump if a filesystem not in
5617 /etc/fstab is given to it.
5619 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5620 that most of the other mount utilities understands.
5622 Mke2fs will make a filesystem even if it appears mounted if the force
5625 Dumpe2fs has new command-line options which allow a filesystem expert
5626 to specify the superblock and blocksize when opening a filesystem.
5627 This is mainly useful when examining the remains of a toasted
5630 The badblocks program has been updated to display correctly on disks
5631 with large block numbers.
5633 The badblocks program no longer gives spurious errors when errors
5634 occur on non-block boundaries, which is common if the blocksize is
5637 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5638 MKE2FS_SYNC environment variable is set. This is to work around a VM
5639 bug in the 2.0 kernel. I've heard a report that a RAID user was able
5640 to trigger it even using a 2.2 kernel, but hopefully it will not be
5641 needed for most Linux 2.2 users.
5643 Fixed miscellaneous documentation and man pages.
5648 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5649 in e2fsck's pass1.c really should have been static.
5651 The return value of the uuid_compare() function was changed to make it
5652 match with the convetions used by strcmp, memcmp, and Paul Leach's
5653 UUID sample document.
5655 The "make depend" process has now been made more automated; it now
5656 automatically word-wraps the dependencies, and only replaces source
5657 Makefile.in if there has been a change in the dependencies. Also, a
5658 top-level "make depend" now recurses through all the subdirectories
5661 The Makefile in .../util has been changed so that subst is built using
5662 the native C compiler during a cross-compilation, since the subst
5663 program is only used during the build process. Also add an explicit
5664 rule to build util/subst by cd'ing to the correct directory and
5667 The man directories are defined in terms mandir, so that the configure
5668 script can override the location of the manual pages.
5670 The config files have been updated to recognize new machine types for
5671 both the i386 and alpha families.
5673 Fsck has been modified so that it will accurately create an
5674 fsck_instance even when the noexecute flag is set. This allows for
5675 accurate debugging of the fsck pass structure. Also, when the verbose
5676 flag is given twice, fsck will print debugging information about when
5677 fsck is waiting for jobs to finish.
5680 E2fsprogs 1.14 (January 9, 1999)
5681 ================================
5683 Fix the fstab parsing code so that it can handle blank lines and
5684 comment characters. Also, missing pass numbers need to be treated as
5687 Fixed a bug in e2fsck where under some circumstances (when e2fsck
5688 needs to restart processing after fixing an egregious inconsistency)
5689 it would try to access already freed memory.
5691 E2fsck now prints non-printable characters in directory entries and
5692 pathnames using '^' and 'M-' notation.
5694 Fixed chattr so that it will ignore symbolic links when doing
5695 recursive descent traversals. For both chattr and lsattr, no longer
5696 print the version string unless the -V option is given.
5698 Allow the system administrator to directly specify the number of
5699 inodes desired in the filesystem, for some special cases where this is
5702 Fix portability problems so that e2fsprogs can be compiled under Linux
5703 1.2 systems and Solaris systems.
5705 Update the config.guess file with a more recent version that will
5706 identify newer Linux platforms.
5711 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5712 an inode number of zero is passed to them.
5714 E2fsprogs 1.13 (December 15, 1998)
5715 ==================================
5717 Fixed a bug in debugfs where an error messages weren't getting printed
5718 when the ext2 library routines to read inodes returned errors in the
5719 stat, cmri and rm commands.
5721 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5722 provided, it won't create an inode table smaller than the minimum
5723 number of inodes required for a proper ext2 filesystem.
5725 Fsck now parses the /etc/fstab file directly (instead of using
5726 getmntent()), so that it can distinguish between a missing pass number
5727 field and pass number field of zero. This caused problems for
5728 diskless workstations where all of the filesystems in /etc/fstab have
5729 an explicit pass number of zero, and fsck could not distinguish this
5730 from a /etc/fstab file with missing pass numbers.
5732 E2fsck will create a /lost+found directory if there isn't one in the
5733 filesystem, since it's safer to create the lost+found directory before
5736 Fixed e2fsck so that it would detect bogus immutable inodes which
5737 happen to be sockets and FIFO files, and offer to clear them.
5739 If a filesystem has multiple reasons why it needs to be checked, and
5740 one of the reasons is that it is uncleanly mounted, e2fsck will print
5741 that as the reason why the filesystem is being checked.
5743 Cleaned up the output routines of mke2fs so that it doesn't overflow
5744 an 80 column display when formating really big filesystems.
5746 Added a sanity check to e2fsck to make sure that file descriptors 0,
5747 1, 2 are open before opening the hard disk. This avoids a problem
5748 where a broken program might exec e2fsck with those file descriptors
5749 closed, which would cause disastrous results if the kernel returns a
5750 file descriptor for the block device which is also used by FILE *
5753 Fixed up the e2fsck progress reporting functions so that the values
5754 reliably reach 100% at the completion of all of the e2fsck passes.
5756 Fixed minor documentation bugs in man pages and usage messages.
5761 Fixed a number of lint warnings in the ext2fs library and potential
5762 portability problems from other OS's header files that might define
5763 CPP macros for names like "max" and "min".
5765 ext2fs_badblocks_list_add() has been made more efficient when it needs
5766 to grow the bad blocks list.
5768 Fixed a bug in e2fsck which caused it to dereference a freed pointer
5769 just before exiting.
5771 Fixed the substition process for generating the mk_cmds and compile_et
5772 scripts so that they will work outside of the build tree.
5774 Add sanity check to e2fsck so that if an internal routine
5775 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5776 and causing a core dump. This should never happen, but...
5778 E2fsprogs 1.12 (July 9, 1998)
5779 ==================================
5781 E2fsprogs now works with glibc (at least with the version shipped wtih
5782 RedHat 5.0). The ext2fs_llseek() function should now work even with
5783 i386 ELF shared libraries and if llseek() is not present. We also
5784 explicitly do a configure test to see if (a) llseek is in libc, and
5785 (b) if llseek is declared in the system header files. (See standard
5786 complaints about libc developers don't understand the concept of
5787 compatibility with previous versions of libc.)
5789 The ext2fs library now writes out the block group number in each of
5790 the superblock copies. This makes it easier to automatically
5791 determine the starting block group of the filesystem when the block
5792 group information is trashed.
5794 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5795 which means that e2fsprogs will ignore the high 8 bits of the
5796 directory entry's name_len field, so that it can be used for other
5799 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5800 E2fsprogs will now support filesystems with 64-bit sized files.
5802 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5804 Added new program "e2label", contributed by Andries Brouwer. E2label
5805 provides an easy-to-use interface to modify the filesystem label.
5807 Fixed bug so that lsattr -v works instead of producing a core dump.
5809 Fixed a minor bug in mke2fs so that all groups with bad superblock
5810 backup blocks are printed (not just the first one).
5812 Mke2fs will check the size of the device, and if the user specifies a
5813 filesystem size larger than the apparent size of the device it will
5814 print a warning message and ask if the user wants to proceed.
5816 E2fsck has a new option -C, which sends completion information to the
5817 specified file descriptor. For the most part, this is intended for
5818 programs to use, although -C 0 will print a spinning character to the
5819 stdout device, which may be useful for users who want to see something
5820 happening while e2fsck goes about its business.
5822 Fixed a bug in e2fsck which could cause a core dump when it needs to
5823 expand the /lost+found directory, and sometimes the bitmaps haven't
5824 been merged in. Also fixed a related bug where ext2fs_write_dir_block
5825 was used to write out a non-directory block. (Which would be bad on a
5826 non-Intel platform with byte swapping going on.)
5828 Fixed bug in e2fsck where it would print a "programming error" message
5829 instead of correctly identifying where a bad block was in used when
5830 the bad block was in a non-primary superblock or block group
5831 descriptor. Also fixed a related bug when sparse superblocks are in
5832 use and there is a bad block where a superblock or block group
5833 descriptor would have been in a group that doesn't include a
5836 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5837 the block group descriptor table is corrupt, it was possible to try to
5838 allocate a huge array, fail, and then abort e2fsck.
5839 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5840 and subsitutes reasonable values if the descriptors are obviously bogus.
5842 If e2fsck finds a device file which has the immutable flag set and the
5843 i_blocks beyond the normal device number are non-zero, e2fsck will
5844 offer to remove it, since it's probably caused by garbage in the inode
5847 When opening a filesystem, e2fsck specially checks for the EROFS error
5848 code, and prints a specific error message to the user which is more
5851 If the filesystem revision is too high, change the e2fsck to print
5852 that this is either because e2fsck is out of date, or because the
5853 superblock is corrupt.
5855 E2fsck now checks for directories that have duplicate '.' and '..'
5856 entries, and fixes this corruption.
5858 E2fsck no longer forces a sync of the filesystem (with attendant sleep
5859 calls) at all times. The ext2fs_flush() function now performs a sync
5860 only if it needed to write data blocks to disk.
5862 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5863 certain errors would not be properly reported.
5865 Updated and expanded a few points in the man pages which users
5866 complained wheren't explicit enough.
5868 Added special case byte-swapping code if compiling on the PowerPC, to
5869 accomodate the strange big-endian variant of the ext2 filesystem that
5870 was previously used on the PowerPC port.
5876 Removed C++ keywords from the ext2fs libraries so that it could be
5879 E2fsck's internal organization has now been massively reorganized so
5880 that pass*.c don't have any printf statements. Instead, all problems
5881 are reported through the fix_problem() abstraction interface. E2fsck
5882 has also been revamped so that it can be called as a library from a
5885 Added new fileio primitives in libext2fs for reading and writing
5886 files on an unmounted ext2 filesystem. This interface is now used by
5889 Added a new libext2fs function for mapping logical block numbers of
5890 a file to a physical block number.
5892 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5893 a block, zeros it, and updates the filesystem accounting records
5896 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5897 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5899 The libext2fs functions now use a set of memory allocation wrapper
5900 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5901 instead of malloc, free, and resize. This makes it easier for us to
5902 be ported to strange environments where malloc, et. al. aren't
5903 necessarily available.
5905 Change the libext2fs fucntion to return ext2-specific error codes
5906 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5907 and depending on the existence of system error codes (such as EEXIST
5910 Renamed io.h to ext2_io.h to avoid collision with other OS's header
5913 Add protection against ext2_io.h and ext2fs.h being included multiple
5916 The types used for memory lengths, etc. have been made more portable.
5917 In generla, the code has been made 16-bit safe. Added Mark
5918 Habersack's contributed DOS disk i/o routines.
5920 Miscellaneous portability fixes, including not depending on char's
5923 The io_channel structure has a new element, app_data, which is
5924 initialized by the ext2fs routines to contain a copy of the filesystem
5927 ext2fs_check_directory()'s callback function may now return the error
5928 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5929 really do the checking, despite the presence of the callback function.
5932 E2fsprosg 1.11 (June 17, 1997)
5933 ==============================
5935 Fixed e2fsck to detect (previously ignored) conflicts between the
5936 superblock or block group descriptors and block bitmaps, inode
5937 bitmaps, and inode tables.
5939 Fixed bug in e2fsck so that when the message printed out when a block
5940 or inode bitmap conflicts with other data, it has the correct group
5943 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5944 to badblocks. This meant that not all of the filesystem was being
5945 tested for bad blocks!
5947 Fixed an array boundary overrun case which cropped up in
5948 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5951 Adjusted the number of columns printed by mke2fs when displaying the
5952 superblock backups to avoid running over 80 columns when making a
5953 really big filesystem.
5955 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5956 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5957 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5962 Fixed install rule in lib/ss so that ss_err.h is actually getting
5965 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5966 bassed back to the caller.
5968 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5969 setting the current inode number (which meant this function wasn't
5972 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5973 blocks in the bitmap when increasing the size of the bitmap.
5975 Changed the initial number of blocks allocated by ext2fs_init_dblist()
5976 to be more realistic.
5978 Added a new function ext2fs_allocate_group_table, which sets up the
5979 group descriptor information (and allocates inode and block bitmaps,
5980 and inode tables for a particular group). The function was created by
5981 factoring out code form ext2fs_allocate_tables().
5983 Added a new function ext2fs_move_blocks which takes a bitmap of the
5984 blocks to be moved, and moves them to another location on the
5987 Make the unix_io channel's io_channel_flush implementation calls sync()
5988 to to flush the kernel buffers to disk.
5990 Added a new function ext2fs_dblist_count returns the number of
5991 directory blocks in dblist.
5994 E2fsprogs 1.10 (April 24, 1997)
5995 ===============================
5997 Mke2fs once again defaults to creating revision #0 filesystems, since
5998 people were complaining about breaking compatibility with 1.2 kernels.
5999 Warning messages were added to the mke2fs and tune2fs man pages that
6000 the sparse superblock option isn't supported by most kernels yet (1.2
6001 and 2.0 both don't support parse superblocks.)
6003 Added new flag to mke2fs, -R <raid options>, which allows the user to
6004 tell mke2fs about the RAID configuration of the filesystem. Currently
6005 the only supported raid option is "stride" which specifies the width
6008 Fixed bug in e2fsck where pass1b would bomb out if there were any
6009 blocks marked bad in the inode table.
6011 Fixed rare bug in mke2fs where if the user had a very unlucky number
6012 of blocks in a filesystem (probability less than .002) the resulting
6013 filesystem would be corrupt in the last block group.
6015 Fixed bug where if e2fsck tried to allocate a block to fix a
6016 filesystem corruption problem and the filesystem had no free blocks,
6017 ext2fs_new_block() would loop forever.
6019 The configure script now checks explicitly to see if "-static" works,
6020 since that can't be assumed to be true --- RedHat doesn't install
6021 libc-static by default.
6023 Fixed bug in libext2's block iterator functions where under some
6024 cirmcustances, file with holes would cause the bcount parameter to the
6025 callback function to be incorrect. This bug didn't affect any of
6026 e2fsprogs programs, but it was discovered by Paul Mackerras, the
6027 author of the PPC boot loader.
6029 Removed use of static variables to store the inode cache in libext2fs.
6030 This caused problems if more than one filesystem was accessed via
6031 libext2fs (static variables in libraries are generally a bad idea).
6032 Again, this didn't affect e2fsprogs programs, but it was discovered by
6035 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6036 will compile cleanly with 1.2.13 kernels (even with a.out shared
6042 Added new functions to duplicate an ext2 filesystem handle, and its
6043 associated substructure. New functions: ext2fs_dup_handle(),
6044 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6045 Other structures, such as the io_channel and the inode_cache, now have
6046 a ref count so that they only get freed when they are no longer used
6047 by any filesystem handle. (These functions were added as part of the
6048 development effort for an ext2 resizer).
6050 E2fsprogs 1.09 (April 14, 1997)
6051 ===============================
6053 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6054 accidentally introduced in the 1.08 release. The overhead calculation
6055 was accidentally removed, which caused ext2fs_initialize() to not
6056 notice when the filesystem size needed to be adjusted down because
6057 there wasn't enough space in the last block group.
6059 Fixed bug in version parsing library routine; it was always parsing
6060 the library version string, instead of using the passed-in string.
6062 Clarified chattr man page.
6064 E2fsprogs 1.08 (April 10, 1997)
6065 ===============================
6067 E2fsck 1.07 was very slow when checking very large filesystems with a
6068 lot of files that had hard links (i.e., news spools). This was fixed
6069 by seriously revamping the icount abstraction. Added a formal test
6070 suite for the icount abstraction.
6072 Debugfs now has a "-l" option to the "ls" command, which lists the
6073 inode number, permissions, owner, group, size, and name of the files
6076 Fix a bug in e2fsck where when a directory had its blocks moved to
6077 another location during the pass 1b processing, the directory block
6078 list wasn't updated, so pass 2 wouldn't check (and correct) the
6079 correct directory block.
6081 E2fsck will now treat inodes which contain blocks which are claimed by
6082 the filesystem metadata by treating them as multiply claimed blocks.
6083 This way, the data in those blocks can be copied to a new block during
6084 the pass 1b--1d processing.
6086 E2fsck will attempt to determine the correct superblock number and
6087 display it in the diagnostic and warning messages if possible.
6089 Add support for a new (incompatible) feature, "sparse_super". This
6090 feature reduces the number of blocks which contain copies of backup
6091 superblocks and block group descriptors. (It is only an incompatible
6092 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
6093 support a new -s option; e2fsck will recognize filesystems built with
6094 this feature turned on.
6096 E2fsck now checks the library to make sure is the correct version,
6097 using new library functions. (This helps to diagnose incorrectly
6098 installed e2fsprogs distributions.)
6100 Dumpe2fs now prints more information; its now prints the the
6101 filesystem revision number, the filesystem sparse_super feature (if
6102 present), the block ranges for each block group, and the offset from
6103 the beginning of the block group.
6105 Mke2fs now distributes the inode and block bitmap blok so that the
6106 won't be concentrated in one or two disks in RAID/striping setups.
6107 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6108 choose the largest blocks per group that be chosen. (For 2k blocks,
6109 you can have up to 16384 blocks/group; for 4k blocks, you can have up
6110 to 32768 blocks/group.) Previously mke2fs would not allow
6111 specification of more than 8192 blocks per group, even if you were
6112 using a 2k or 4k block group.
6117 Added a new function ext2fs_create_icount2() which takes a "hint"
6118 argument. This hint argument presets the icount array with the list
6119 of inodes which actually need to be in the icount array. This really
6120 helps to speed up e2fsck.
6122 Added a new function ext2fs_icount_validate() which checks the rep
6123 invariant for the icount structure. This is used mostly for testing.
6125 The error mesasage given when a bad inode number is passed to
6126 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6127 EXT2FS_UNMARK_ERROR).
6129 Added a new function ext2fs_set_dir_block which sets the block of a
6130 dblist entry, given the directory inode and blockcnt.
6132 Added a new function ext2fs_get_library_version() which returns the
6133 current library version, and ext2fs_parse_version_string() which
6134 returns a version number based on a e2fsprogs version string.
6136 The icount functions will return EINVAL if the passed in inode number
6139 E2fsprogs 1.07 (March 9, 1997)
6140 ==============================
6142 E2fsck is now uses much less memory when checking really large
6143 filesystems (or rather, filesystems with a large number of inodes).
6144 Previously a filesystem with 1 million inodes required 4 megabytes of
6145 memory to store inode count statistics; that storage requirement has
6146 now been reduced to roughly half a megabyte.
6148 E2fsck can now properly deal with bad blocks appearing inside the
6149 inode table. Instead of trying to relocate the inode table (which
6150 often failed because there wasn't enough space), the inodes in the bad
6151 block are marked as in use.
6153 E2fsck will automatically try to use the backup superblocks if the
6154 primary superblocks have a bad magic number or have missing meta-data
6155 blocks (or meta-data blocks which are out of range).
6157 E2fsck's pass 3 has been made more efficient; most noticeable on
6158 filesystems with a very large number of directories.
6160 Completely revamped e2fsck's system of printing problem reports. It
6161 is now table driven, to make them more easily customizeable and
6162 extendable. Error messages which can be printed out during preen mode
6163 are now one line long.
6165 Fixed e2fsck's filesystem swapping code so that it won't try to swap
6166 fast symbolic links or deleted files.
6168 Fixed e2fsck core dumping when fixing a filesystem which has no
6169 directories (not even a root directory).
6171 Added a check to e2fsck to make sure that the length of every
6172 directory entry is a multiple of 4 (since the kernel complains if it
6175 Added a check to e2fsck to make sure that a directory entry isn't a
6176 link to the root directory, since that isn't allowed.
6178 Added a check to e2fsk to now make sure the '.' and '..' directory
6179 entries are null terminated, since the 2.0 kernel requires it.
6181 Added check to write_bitmaps() to make sure the superblock doesn't get
6182 trashed if the inode or block bitmap is marked as being block zero.
6184 Added checking of the new feature set fields in the superblock, to
6185 avoid dealing with new filesystem features that this package wasn't
6188 Fixed a fencepost error in ext2fs_new_block() which would occasionally
6189 try to allocate a block beyond the end of a filesystem.
6191 When the UUID library picks a random IEEE 802 address (because it
6192 can't find one from a network card), it sets the multicast bit, to
6193 avoid conflicting with a legitimate IEEE 802 address.
6195 Mke2fs now sets the root directory's owner to be the real uid of the
6196 user running mke2fs. If the real uid is non-zero, it also sets
6197 the group ownership of the root directory to be the real group-id of
6198 the user running mke2fs.
6200 Mke2fs now has more intelligent error checking when it is given a
6201 non-existent device.
6203 When badblocks is given the -vv option, it now updates the block that
6204 it is currently testing on every block.
6206 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6207 currently correctly if PATH wasn't already set.
6209 Shared libraries now built with dependencies. This allows the shared
6210 library files to be used with dlopen(); it also makes the transition
6211 to libc 6 easier, since ld.so can tell which libc a particular shared
6212 library expects to use.
6217 Added new abstraction (defined in dblist.c) for maintaining a list of
6218 blocks which belongs to directories. This is used in e2fsck and other
6219 programs which need to iterate over all directories.
6221 Added new functions which test to see if a contiguous range of blocks
6222 (or inodes) are available. (ext2fs_*_bitmap_range).
6224 Added new function (ext2_inode_has_valid_blocks) which returns true if
6225 an inode has valid blocks. (moved from e2fsck code).
6227 Added new function (ext2fs_allocate_tables) which allocates the
6228 meta-data blocks as part of initializing a filesystem. (moved from
6231 Added a new I/O manager for testing purposes. It will either allow a
6232 program to intercept I/O requests, or print debugging messages to
6233 trace the activity of a program using the I/O manager.
6235 The badblocks_list functions now store the bad blocks in a sorted
6236 order, and use a binary search to speed up badblocks_list_test.
6238 The inode scan function ext2fs_get_next_inode() may now return a soft
6239 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6240 those cases where part of an inode table is missing or there is a bad
6241 block in the inode table.
6243 Added a new function (ext2fs_block_iterate2) which adds new arguments to
6244 the callback function to return a pointer (block and offset) to the
6245 reference of the block.
6247 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6248 application to jump to a particular block group while doing an inode
6251 The badblocks list functions were renamed from badblocks_* to
6252 ext2fs_badblocks_*. Backwards compatibility functions are available
6253 for now, but programs should be modified to use the new interface.
6255 Some of the library functions were reorganized into separate files to
6256 reduce the size of some programs which statically link against the
6259 Put in some miscellaneous fixes for the Alpha platform.
6262 E2fsprogs 1.06 (October 7, 1996)
6263 ================================
6265 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6266 smash the backup copies in ext2fs_close(). (The problem was that when
6267 e2fsck -p discovered the problem, while it was closing the filesystem
6268 and exiting, it was also blowing away the backup superblocks on the
6269 disk, which was less than friendly.) We now make it the case that we
6270 only write out the backup superblock and the back block descriptors if
6271 the filesystem is completely free from problems.
6273 Fixed a bug in block_interate in the lib/ext2fs library which caused
6274 e2fsck to fail on GNU Hurd-created filesystems.
6276 Add support for Linux/FT's bootloader, which actually uses
6277 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6280 Add support for the "A" (no atime update) attribute. (Note: this
6281 attribute is not yet in production kernels.)
6283 The test suite is not automatically run when doing a "make all" from
6284 the top level directory. Users should manually run "make check" if
6285 they wish to run the test suite.
6287 Upon a preenhalt(), make the printed message more explicit that
6288 running e2fsck "MANAULLY" means without the -p or -a options.
6290 In e2fsck, if a disconnected inode is zero-length, offer to clear it
6291 instead of offering to connect it to lost+found.
6293 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6294 e2fsck to be run over it, change e2fsck to explicitly display this
6297 For dumpe2fs and e2fsck, cause the -V option to print out which
6298 version of the ext2fs library is actually getting used. (This will
6299 help detect mismatches of using a 1.06 utility with a 1.05 library,
6305 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6306 the naming convention.
6308 In ext2fs_initialize(), make sure the description for the inode bitmap
6309 is correctly initialize.
6311 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6313 E2fsprogs 1.05 (September 7, 1996)
6314 ==================================
6316 Add support for new fields in the ext2 superblock --- volume name,
6317 volume UUID, and last mounted field. Dumpe2fs displays these fields,
6318 tune2fs and mke2fs allows you to set them. E2fsck will automatically
6319 generate a UUID for those volumes that don't have them.
6321 Put in support for e2fsck to recognize HURD specific ext2 features ---
6322 most notably, the translator block. The e2fsprogs tools will now use
6323 the creator_os field in the superblock to correctly handle different
6324 OS-specific variants of the ext2 filesystem.
6326 E2fsck now fixes inodes which have a the deletion time set, but which
6327 have a non-zero i_link_count field by offering to clear the deletion
6328 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6329 ext2 kernel behavior) and offered to unlink the file.
6331 If e2fsck sets the clean bit, but nothing else, set the exit code
6332 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6333 set the filesystem valid bit when it was previously cleared. :-) This
6334 was needed to make the HURD fsck driver happy.
6336 If the user refuses to attach an unattached inode, e2fsck will no
6337 longer set the inode's link count. Otherwise, the inode would end up
6338 getting marked as unused, which might cause loss of data later.
6340 Make the message issued by e2fsck when the superblock is corrupt less
6341 confusing for users. It now mentions that another reason for the
6342 "corrupt superblock" message might be that the partition might not be
6343 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6345 Make the libext2 library more robuest so that e2fsck won't coredump on
6346 an illegal superblock where the blocksize is zero. (f_crashdisk is
6349 By default, create filesystems where the default checkinterval is 6
6350 months (180 days). Linux servers can be robust enough that 20 reboots
6351 can be a long, long time.
6353 Added configure flag --enable-old-bitops, which forces the bitops to
6354 use the old (native) bitmask operations. By default on the sparc
6355 platform, the standard ext2 bit ordering is now used.
6357 Added a new feature to e2fsck to byte-swap filesystems; this can be
6358 used to convert old m68k filesystems to use the standard byte-order
6359 storage for the superblock, inodes, and directory blocks. This
6360 function is invoked by using the '-s' option to e2fsck.
6362 Debugfs's "dump" command has been enhanced so that it writes out the
6363 exact size of the file so that the nulls at the end of the file are
6364 eliminated. The command also accept a new "-p" option which will
6365 attempt preserve to preserve the ownernship, permissions, and
6366 file modification/access times.
6368 Debugfs has two new options, -f and -R. The -R option allows the user
6369 to execute a single debugfs command from the command line. The -f
6370 option allows the user to specify a "command file" containing debugfs
6371 commands which will get executed.
6373 Dumpe2fs now pretty prints the check interval, instead of just
6374 printing the check interval as a number of seconds.
6376 Fix bugs in debugfs: the params command when no filesystem is opened
6377 no longer causes a core dump. It is now possible to unlink a file
6378 when a pathame containing a '/' is specified.
6380 Tune2fs has a new -C option which sets the number of times the
6381 filesystem has been mounted.
6383 Fix the chattr '-v' option so that it actually works. Chattr was
6384 being buggy about the -v option parsing.
6389 The directory lib/uuid contains a set of library routines to generate
6390 DCE compatible UUIDs.
6392 Extended ext2fs_namei() to handle symbolic links. Added new function
6393 ext2fs_nami_follow() which will follow last symbolic link in the case
6394 where the pathname points to a sym link.
6396 The ext2fs_block_iterate function will now return the HURD translator
6397 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6398 iterator to return data blocks only. The ext2fs.h file now defines
6399 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6400 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6401 count field of the iterator callback function.
6403 The test script driver now takes an optional second argument, which is
6404 the test case to be run. This allows you to run a test case without
6405 needing to run the entire test suite.
6407 On Linux ELF systems, install the .so files in the correct places
6408 (/usr/lib). The .so files must be stored in the same directory as the
6411 Fixed miscellaneous HURD compilation issues with header file being
6412 included in the right order.
6414 Fixed debugfs so that it resets optind to zero, not one, since setting
6415 optind to zero is more correct.
6418 E2fsprogs 1.04 (May 16, 1996)
6419 =============================
6421 First "official" (1.03 was a limited release only) to support building
6422 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6425 This package includes a RPM specs file, that it can be built using the
6426 RedHat Package Manager.
6428 E2fsck now prints a hint that if there are lots of incorrectly located
6429 inode bitmaps, block bitmaps, and inode table blocks, the user might
6430 want to try using e2fsck -b 8193 first, to see if that fares any
6433 For ext2 filesystem written with the hurd, debugfs will now print out
6434 the translator field when printing an inode structure.
6436 Lots of miscellaneous linking/installation cleanups:
6438 Libraries are now linked using a relative pathname, instead of
6439 relying on -L working correct. It doesn't, in many cases, including
6440 current versions of GNU ld. This guarantees that the build tree is
6441 linking with the right libraries, instead of the ones installed in
6444 Header files, man pages, and the et/ss shell scripts are now
6445 generated using a custom substitution script, instead of relying on
6446 the configure script. This prevents needless recompilation of
6447 files; in addition, the custom substitution script is much faster.
6449 e2fsck may now be linked dynamically, by using the
6450 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6451 since it increases e2fsck's dependence on other files, but some
6452 people need to save disk space, and other critical programs on their
6453 systems were being linked dynamically anyway.
6455 Programs such as fsck which didn't need to be linked against
6456 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6457 only link against libraries they actually need. Otherwise, those
6458 programs would require the presense of libraries that otherwise
6459 could be removed from a rescuse diskette.
6461 The ss include files are now installed correctly so they can
6462 actually be used by another package.
6464 If the profiling libraries are built, they are now installed on a
6465 "make install-libs".
6468 E2fsprogs 1.03 (March 27, 1996)
6469 ===============================
6471 Change the m68k bit numbering for bitmasks to match the bit numbering
6472 used by all other ext2 implementations. (This change was requested by
6473 the m68k kernel development team.)
6475 Support (in-development) filesystem format revision which supports
6476 (among other things) dynamically sized inodes.
6478 Fixed a bug in the ext2 library so that an intelligent error is
6479 returned if mke2fs is run with a ridiculously small number of blocks
6482 Fixed a bug in the ext2 library which required that the device be
6483 openable in read/write mode in order to determine its size. This
6484 caused e2fsck -n to require read/write access when it was not
6485 previously necessary.
6487 Fixed a bug in e2fsck which casued it to occasionally fail the test
6488 suite depending on which version of the floating point library it was
6491 Fixed a bug in e2fsck so that it now halts with a fatal error when
6492 certain superblock consistency checks fail. Previously it continued
6493 running e2fsck, with some potential confusing/damaging consequences.
6495 Added new flag to fsck which allows the root to be checked in parallel
6496 with other filesytems. This is not the safest thing in the world to
6497 do, but some system administrators really wanted it.
6499 Fixed -Wall flames in lib/ss.
6502 E2fsprogs 1.02 (January 16, 1996)
6503 =================================
6505 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6507 Change e2fsck to print statistics of how many non-contiguous files are
6508 on the system. Note that a file which is larger than 8k blocks, it is
6509 guaranteed to be non-contiguous.
6511 In mke2fs, print a warning message if a user tries to format a whole
6512 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6513 whole disk, the -F (force) option forces mke2fs to format a whole disk
6516 Fix a bug in fsck where in some cases it might start checking
6517 partitions in the next pass before it finishes checking partitions in
6518 the current pass. This still won't cause two partitions on the same
6519 disk will be checked, so it's rarely a problem in real life.
6521 Patch lsattr so that it won't hang when checking a named pipe.
6523 Minor compilation fixes:
6524 * Fix the order of libraries that were linked in debugfs.
6525 * Allow the sources to be compiled with -ansi turned on.
