1 E2fsprogs 1.42-WIP (July 2, 2011) -- 1ca87790b91
2 =================================
4 Add support for 64-bit file systems.
6 Add initial support for bigalloc file systems.
8 Fix a bug in e2fsck where if the free blocks and inodes counts are
9 incorrect, e2fsck would fix them without printing an error message.
10 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
11 any explanation of what was fixed.
13 E2fsck will no longer attempt to clone an extended attribute block in
14 pass1b handling if the file system does not support extended
17 E2fsck will be more careful accidentally asking the user to continue
18 if the file system is mounted, so that an escape sequence won't cause
19 a false positive. (Addresses Debian Bug: #619859)
21 E2fsck now uses less cpu time in pass 5 when large portions of the
22 bitmaps are uninitialized.
24 E2fsck will no longer segault when a corrupted file system has a bad
25 extent, and removing it leads to a block needing to be deallocated.
26 (Addresses SourceForge Bug: #2971800)
28 E2fsck now supports an extended "discard" option which will cause
29 e2fsck to attempt discard all unused blocks after a full, successful
32 The e2image program now supports the qcow2 format, which is a more
33 efficient way of capturing file system dumps.
35 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
36 per-device defaults to be specified in the configuration file.
38 Mke2fs now supports the reserved_ratio relation in the [defaults] and
39 [fs_types] section in mke2fs.conf.
41 Mke2fs now creates extent-mapped directories for the root and
42 lost+found directories.
44 Mke2fs will skip zero'ing the journal if the extended option
45 "lazy_journal_init" is specified. This can save a lot of time, but it
46 does add a small amount of risk if the system crashes before the
47 journal is overwritten entirely once. It is epsecially useful for
50 Mke2fs will now create file systems that enable user namespace
51 extended attributes and with time- and mount count-based file
52 system checks disabled.
54 Mke2fs will not set a stride or strip size of one block based on block
55 device attributes obtained from sysfs.
57 Mke2fs now displays a progress report during the discard process.
59 Mke2fs now handles extreme file system parameters correctly which
60 previously caused the inodes per group to drop below 8, leading to a
61 segfault. (The inodes per group must be a multiple of 8, but the code
62 didn't correctly deal with an inodes per group count less than 8.)
64 Debugfs's icheck will now correctly find inodes which use the
65 searched-for block as an extended attribute block.
67 Debugfs now has a new "punch" command which remove blocks from the
70 The badblocks program now correctly recovers from I/O errors when
71 direct I/O is being used. The badblocks command now also supports a
72 -B option which forces the use of buffered I/O, and the -v option will
73 provide a more detailed breakdown of read, write, and failed
76 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
78 Added support for journals larger than 2GB.
80 Support using both hard links and symlinks when installing e2fsprogs.
82 Add overflow checking to tune2fs -i's fsck interval, which must fit in
85 Filefrag will report 0 extents correctly in verbose mode. (Addresses
86 RedHat Bugzilla: #653234)
88 Logsave's usage message has been fixed. (Addresses Debian Bug:
91 Added a useful "fallocate" program to the contrib directory.
93 Update translations: French, Chinese, Germany, Indonesian, Swedish,
94 Vietnamese, Polish, Dutch, Czech,
96 Updated/clarified man pages.
101 The ext2fs library now has the new functions ext2fs_punch(),
102 ext2fs_get_memzero() and ext2fs_file_get_inode().
104 The I/O manager now supports the discard operation.
106 Reserved file system code points for new 1st class quota feature.
108 Fixed a potential free of an unitialized pointer in
109 ext2fs_update_bb_inode().
111 Fixed miscellaneous compile warnings.
113 Fixed portability issues for Mac OS X.
115 Fixed FreeBSD portability where gettext is not in libc.
117 Fixed a build failure when OMIT_COM_ERR is defined.
119 Improved error checking and fixed memory leaks caused by error return
122 Added a regression test for extent-mapped journals by mke2fs and tune2fs.
124 Added a test for creating a large (over 4GB) journal using mke2fs.
126 Fixed the dependencies for "make check" so all required dependencies
127 are built before running the gression tests.
129 A link to com_err.h is installed in $(includedir) during a "make install".
132 E2fsprogs 1.41.14 (December 22, 2010)
133 =====================================
135 Fix spurious complaint in mke2fs where it would complain if the file
136 system type "default" is not defined in mke2fs.conf.
138 The resize2fs program will no longer clear the resize_inode feature
139 when the number reserved group descriptor blocks reaches zero. This
140 allows for subsequent shrinks of the file system to work cleanly for
141 flex_bg file systems.
143 The resize2fs program now handles devices which are exactly 16T;
144 previously it would give an error saying that the file system was too
147 E2fsck (and the libext2fs library) will not use the extended rec_len
148 encoding for file systems whose block size is less than 64k, for
149 consistency with the kernel.
154 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
155 been fixed. (Addresses Sourceforge Bug: #3138115)
157 The ext2fs_block_iterator2() function passed an incorrect ref_offset
158 to its callback function in the case of sparse files. (Addresses
159 Sourceforge Bug: #3081087)
161 Fix some type-punning warnings generated by newer versions of gcc.
164 E2fsprogs 1.41.13 (December 13, 2010)
165 =====================================
167 E2fsck now supports the extended option "-E journal_only", which
168 causes it to only do a journal replay. This is useful for scripts
169 that want to first replay the journal and then check to see if it
172 E2fsck will now support UUID= and LABEL= specifiers for the -j option
173 (which specifies where to find the external journal). (Addresses
176 E2fsck now has support for the problems/<problem code>/force_no
177 configuration option in e2fsck.conf, which forces a problem to not be
180 Dumpe2fs will now avoid printing large negative offsets for the bitmap
181 blocks and instead print a message which is a bit more helpful for
182 flex_bg file systems.
184 Mke2fs will now check the file system type (specified with the -t
185 option) to make sure it is defined in the mke2fs.conf file; if it is
186 not, it will print an error and abort. If the usage type (specified
187 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
188 warning but will continue. (Addresses Debian Bug #594609)
190 Clarified error message from resize2fs clarifying that on-line
191 shrinking is not supported at all. (Addresses Debian Bug #599786)
193 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
194 displayed. (Addresses Debian Bug #555456)
196 E2fsck will open the external journal in exclusive mode, to prevent
197 the journal from getting truncated while it is in use due to a user
198 accidentally trying to run e2fsck on a snapshotted file system volume.
199 (Addresses Debian Bug #587531)
201 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
204 The tune2fs program can now set the uninit_bg feature without
207 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
208 default mount options settings which were added in 2.6.35.
210 The e2fsck and dumpe2fs programs now support the new ext4 superblock
211 fields which track where and when the first and most recent file
212 system errors occurred. These fields are displayed by dumpe2fs and
213 cleared by e2fsck. These new superblock fields were added in 2.6.36.
215 Debugfs now uses a more concicse format for listing extents in its
216 stat command. This format also includes the interior extent tree
217 blocks, which previously was missing from stat's output for
220 Debugfs has a new option, -D, which will request Direct I/O access of
223 Mke2fs will skip initializing the inode table if a device supports
224 discard and the discard operation will result in zero'ed blocks.
226 Badblocks will now correctly backspace over UTF-8 characters when
227 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
228 Debian Bugs #583782 and #587834)
230 E2freefrag will now display the total number of free extents.
232 Resize2fs -P no longer requires a freshly checked filesystem before
233 printing the minimum resize size.
235 Fixed a floating point precision error in a binary tree search routine
236 that can lead to seg fault in e2fsck and resize2fs.
238 Fixed a bug in e2fsck where if both the original and backup superblock
239 are invalid in some way, e2fsck will fail going back to the original
240 superblock because it didn't close the backup superblock first, and
241 the exclusive open prevented the file system from being reopened.
243 Fixed a big in e2freefrag which caused getopt parsing to fail on
244 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
246 Clarified an mke2fs error message so a missed common in an -E option
247 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
248 results in a more understandable explanation to the user.
250 Mke2fs now displays the correct valid inode ratio range when
251 complaining about an invalid inode ratio specified by the user.
253 Mke2fs now understands the extended option "discard" and "nodiscard",
254 and the older option -K is deprecated. The default of whether
255 discards are enabled by default can be controled by the mke2fs.conf
258 Mke2fs's handling of logical and physical sector sizes has been
259 improved to reflect the fact that there will be some SSD's with 8k and
260 16k physical sectors arriving soon. Mke2fs will no longer force block
261 size to be the physical sector size, since there will be devices where
262 the physical sector size is larger than the system's page size, and
263 hence larger than the maximal supported block size. In addition, if
264 the minimal and optimal io size are not exported by the device, and
265 the physical sector size is larger than the block size, the physical
266 sector size will be used to set the Raid I/O optimization hints in the
269 E2fsck will now display a better, more specific error message when the
270 user enters a typo'ed device name, instead of blathering on about
271 alternate superblocks.
273 Fixed various Debian Packaging Issues
275 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
276 #589345, #591083; Addresses Launchpad Bug: #505719)
278 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
279 Polish, Swedish, and Vietnamese translations.
285 Fix a dependency definition for the static and profiled blkid
286 libraries which could cause compile failures in some configurations.
287 (Addresses Debian Bug: #604629)
289 Add support for Direct I/O in the Unix I/O access layer.
291 Fixed a memory leak in the Unix I/O layer when changing block sizes.
293 Fixed minor memory leaks in mke2fs.
295 Added a new function to the ext2fs library, ext2fs_get_memalign().
297 The tst_super_size test program will check to make sure the superblock
298 fields are correctly aligned and will print them out so they can be
299 manually checked for correctness.
301 Fixed some makefile dependencies for test programs in lib/ext2fs.
303 Reserved the feature flags and superblock fields needed for the Next3
306 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
307 EXT4_INCOMPAT_EA_INODE.
310 E2fsprogs 1.41.12 (May 17, 2010)
311 ================================
313 Mke2fs now gives a correct error message if the external journal
314 device is not found. (Addresses Red Hat Bug #572935)
316 Resize2fs -P will now refuse to print a minimum size if the file
317 system is not clean. Previously it would go ahead and print a minimum
318 size anyway, which might not be correct, leading to user confusion.
320 E2fsck now tests for extents that begin at physical block 0 and
321 rejects them as invalid. (Addresses Google Bug: #2573806)
323 Fixed a bug in e2fsck which could cause it to crash when trying to
324 remove an invalid extent and the block bitmaps hadn't yet been loaded.
325 (Addresses SourceForge Bug: #2971800)
327 E2fsck now will completely skip time-based checks if the system clock
328 looks insane or the option broken_system_clock is set in
331 E2fsck would previously report an i_blocks corruption for a 4T file
332 created using posix_fallocate; this bug has been fixed.
334 E2fsck will now correctly mark a sparse journal as invalid and will
335 delete and recreate the journal to address the problem.
337 E2fsck would previously incorrectly ask the user whether she would
338 like to abort the file system check after finding a problem --- and
339 then abort regardless of the user's answer. This is annoying, and
342 E2fsck can now continue even if it fails to recreate the resize
343 inode; previously it would just abort the file system check
346 E2fsck could potentially remove directory entries for inodes found in
347 the unused region of the inode table; this would generally happen on
348 ext4 file systems that do not use journaling. This bug has been fixed
349 by not clearing these directory entries once it has been established
350 that bg_unused_inodes may not be trustworthy; once pass #2 has been
351 completed, e2fsck will restart the file system check from the
352 beginning, and then it will be safe to delete any directory entries
353 pointing to inodes that appear to be deleted. (Addresses Google Bug:
356 E2fsck will not try to set the block group checksums if the user
357 cancels the fsck with a control-C. It's a bad idea to set the
358 checksums if e2fsck hasn't been completed, and it often results an the
359 error message, "Inode bitmap not loaded while setting block group
360 checksum info". (Addresses Launchpad Bug: #582035)
362 The mke2fs program now queries the kernel for the physical as well as
363 the logical sector size, and will not allow a blocksize below the
364 logical, and will strongly encourage a blocksize at least as big as
365 the physical blocksize. This is needed for 4k sector drives that
366 emulate 512 byte sector sizes.
368 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
369 rarely needed, but it is a legal value.
371 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
372 not needed, and offer to clear it; this is a sign of a kernel bug, but
373 more importantly, some released kernels may crash when this situation
374 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
376 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
377 i_size is correct. (Kernels starting with 2.6.34 will set
380 The com_err library will now only output ^M (a CR character) when the
383 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
384 and Vietnamese translations.
386 Fixed various Debian packaging issues --- see debian/changelog for
387 details. (Addresses Debian Bugs: #571247, #563487)
393 The regression test suite now uses its own mke2fs.conf file, so that
394 downstream distributions want change the mke2fs.conf file which is
395 distributed in the RPM or dpkg file, without worrying about screwing
396 up the regression test results.
398 Always build namei.o so that building with configure --disable-debugfs
399 works correctly. Long-term, if we care about reduced e2fsprogs
400 builds, we need a more general solution for deciding what .o files are
401 needed for a particular build. Given that install floppies are going
402 (gone?) the way the dodo bird, we probably don't care, though.
403 (Addresses Sourceforge Bug: #2911433)
405 Add configure options --enable-symlink-build and
406 --enable-symlink-install, which allow e2fsprogs be built using
407 symlinks instad of hard links, and to be installed using symlinks
408 instead of hard links, respectively. It is useful when the file
409 system where the build is taking place, or the file system where
410 e2fsprogs is installed, can't handle hard links for some reason.
411 (Addresses Sourceforge Bug: #1436294)
413 Fixed compile warning in mke2fs.c.
416 E2fsprogs 1.41.11 (March 14, 2010)
417 ==================================
419 E2fsck will no longer give a fatal error and abort if the physical
420 device has been resized beyond 2**32 blocks. (Addresses Launchpad
423 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
424 the allocation status of the block <blk>. (Addresses Debian Bug:
427 E2fsck now prints a much more emphatic and hopefully scary message
428 when a file system is detected as mounted while doing a read/write
429 check of the filesystem. Hopefully this will dissuade users from
430 thinking, "surely that message doesn't apply to *me*" :-(
432 E2fsck -n will now always open the file system read-only. We now
433 disallow certain combination of options which previously were manual
434 exceptions; this is bad because it causes users to think they are
435 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
436 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
438 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
439 it detected a badly aligned partition. Unfortunately, this broke some
440 distribution installation scripts, so it now just prints the warning
441 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
442 Launchpad Bug: #530071)
444 Mke2fs would take a long time to create very large journal files for
445 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
448 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
449 2.6.34 kernels to make e2fsck not complain about blocks deliberately
450 fallocated() beyond an inode's i_size.
452 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
453 e2fsck -fD can corrupt non-indexed directories when are exists one or
454 more file names which alphabetically sort before ".". This can happen
455 with ext2 filesystems or for small directories (take less than a lock)
456 which contain filenames that begin with a space or some other
457 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
464 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
467 The libcom_err function now has support for Heimdal's com_right_r
468 function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
472 E2fsprogs 1.41.10 (February 7, 2010)
473 ====================================
475 Fix resize2fs bug which causes it to access invalid memory.
477 Add libss support for libreadline.so.6.
479 Fix e2fsck's check for extent-mapped directory with an incorrect file
482 Add new e2fsck.conf configuration option, default/broken_system_clock
483 to support systems with broken CMOS hardware clocks. Also, since too
484 many distributions seem to have broken virtualization scripts now,
485 e2fsck will by default accept dates which are off by up to 24 hours by
486 default. (Addresses Debian Bugs: #559776, #557636)
488 Fix a bug where mke2fs may not use the best placement of the inode
489 table when there is only room for a single block group in the last
492 E2fsck is now smarter when it needs to allocate blocks in the course
493 of fixing file system problems. This reduces the number of spurious
494 differences found in pass #5.
496 E2fsck will no longer rehash directories which fit in a single
499 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
500 sparse directories which use extents).
502 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
504 Fix a bug in filefrag where on platforms which can allow file systems
505 with 8k blocks, that it doesn't core dump when it sees a file system
506 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
509 E2fsck will correctly fix directories that are have an inaccurate
510 i_size as well as other problems in a single pass, instead of
511 requiring two e2fsck runs before the file system is fully fixed.
513 Fix e2fsck so it will correctly find and detect duplicate directory
514 entries for non-indexed directories. ( Addresses Sourceforge Bug:
517 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
518 thinly-provisioned storage device. This can be disabled using the -K
521 Enhance libext2fs so it works around bug in Linux version 2.6.19
522 and earlier where the /proc/swaps file was missing the header on
525 Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
526 was missing the header on the first line.
528 Fix some big-endian bugs in e2fsck and libext2fs.
530 Fix resize2fs so it works correctly on file systems with external
531 journals instead of failing early with the error "Illegal inode
534 Fix libss so that it does not seg fault when using a readline library
535 which does not supply a readline_shutdown() function.
537 Updated dumpe2fs's usage message so it correctly gives the right
538 arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
539 (Addresses Launchpad Bug: #448099)
541 Teach libext2fs to ignore the high 32 bits of the i_blocks field
542 when huge_file file system feature is set, but the inode does not
543 have the HUGE_FILE_FL flag set.
545 Fix e2fsck's handling of 64-bit i_blocks fields.
547 E2fsck will now print "Illegal indirect block", "Illegal
548 double-indirect block", etc., instead of "Illegal block #-1" or
549 "Illegal block #-2", etc. This makes it easier for users to
550 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
552 Mke2fs now will obtain get device topology information from blkid and
553 use it to populate the superblock stride and stripe sizes. It will
554 also warn if the block device is misaligned
556 Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
559 Fix the libext2fs library code to round up the bitmap size to a 4-byte
560 boundary, to prevent spurious seg faults caused by the x86
561 architecture. This doesn't affect Linux systems, but was a major
562 problem on a number of *BSD systems. (Addresses Sourceforge Bug:
565 Fix resize2fs's minimum size required for a file system so it doesn't
566 fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
568 Dumpe2fs now prints summary information about the contents of the
571 Avoid printing scary error messages when e2fsck starts running
572 problems on low-memory systems, as it tends to panic and mislead the
573 user. (Addresses Debian Bug: #509529)
575 Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
576 modules files. (Address Red Hat Bug: #518572)
578 Fix tune2fs so it can add a journal when an extent-enabled file system
579 is mounted. (Addresses Launchpad bug: #416648)
581 Update Czech, Indonesian, Polish and Vietnamese translations (from the
582 Translation Project).
584 Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
586 Fixed various Debian packaging issues --- see debian/changelog for
587 details. (Addresses Debian Bugs: #540111)
592 The configure script supports the --with-cc, --with-ccopts, and
593 --with-ldopts options. Instead, the more standard use of CC=,
594 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
595 Also, --with-ld, which never worked, was also removed.
596 (Addresses Sourceforge Bug: #2843248)
598 The in-tree header files are only used if the in-tree uuid or blkid
599 libraries are used. Otherwise, use the system-provided uuid or blkid
600 header files if using the system-provided libraries.
602 Fix some build failures caused by --disable-* configure options.
604 Work around a bug in autoconf 2.64.
607 E2fsprogs 1.41.9 (August 22, 2009)
608 ==================================
610 Fix a bug in e2fsck routines for reallocating an inode table which
611 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
612 filesystem feature with a relatively rare (and specific) filesystem
613 corruption. This fix causes e2fsck to try to find space for a new
614 portion of the inode table in the containing flex_bg, and if that
615 fails, the new portion of the inode table will be allocated in any
616 free space available in the filesystem.
618 Make e2fsck less annoying by only asking for permission to relocate a
619 block group's inode table once, instead of for every overlapping
620 block. Similarly, only ask once to recompute the block group
621 checksums, instead of once for each corrupted block group's checksum.
623 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
624 not present, and it needs to fall back to using the FIBMAP ioctl.
626 Fix filefrag to correctly print the number of extents for zero-length

629 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
630 to more easily debug the FIBMAP code.
632 Fixed filefrag for non-extent based files.
634 Add a new program, e2freefrag, which displays information about the
635 free space fragmentation in an ext2/3/4 filesystem.
637 Fix inode resizing via tune2fs -I so that it works correctly in the
638 face of non-empty bad blocks inodes, and if the filesystem was
639 formatted using the "mke2fs -E stride=N" option for RAID arrays.
641 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
642 and corrupt large directories if the directory needs to shrink by more
643 than one block. (Addresses Debian Bug: #537510)
645 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
646 last mount times are in the future, they are corrected even if
647 buggy_init_scripts is set. This is needed because otherwise resize2fs
648 will refuse to resize the filesystem, even after running "e2fsck -f".
649 (Addresses Launchpad bug: #373409)
651 E2fsck will now print much fuller information when the last mount time
652 or last written time is in the future, since most people can't seem to
653 believe their distribution has buggy init scripts, or they have a
654 failed CMOS/RTS clock battery.

673 Fixed non-Linux build of the intl directory by adding support for the
676 The bitmap read/write functions now treat uninitialized bitmaps as
677 unallocated; this fixes a number of problems in all e2fsprogs for ext4
678 filesystems when there is a need to allocate new blocks or inodes, and
679 there aren't any free blocks or inodes in the already-used block
682 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
683 get inserted into the extent tree when they are not needed.
686 E2fsprogs 1.41.8 (July 11, 2009)
687 ================================
689 Fix resize2fs's online resizing, fixing a regression which in
690 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
692 Fix potential filesystem corruptions caused by using resize2fs to
693 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
696 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
697 setgid and the currently running program doesn't have write access to
698 the uuidd work directory.
700 Add safety checks (for non-Linux systems) so that uuidd isn't run with
701 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
702 will be careful not to close the file descriptor for its unix domain
703 socket when it detaches itself from the controlling tty. Also add
704 safety checks so that if the unix domain socket between the uuid
705 library and uuidd program is closed for any reason, both the library
706 and the uuidd will return an appropriate error code instead of looping
709 The e2croncheck script, which creates an LVM snapshot and then checks
710 the ext3/4 filesystem via the LVM snapshot, has been added to the

747 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
748 uninitalized data into the portion of the inode beyond the first 128
749 bytes when operating on inodes mapped via extents; potentially
750 corrupting filesystems.
752 Fix memory leaks in e2fsprogs, including a very large memory leak
753 which can cause e2fsck to run out of memory when checking very large
754 filesystems using extents.
756 The logsave program will now filter out the ^A and ^B characters when

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

800 valgrind with the appropriate options to find memory leaks.
803 E2fsprogs 1.41.6 (May 30, 2009)
804 ===============================
806 Fix a critical regression in e2fsck introduced version 1.41.5 which
807 can undo updates to the block group descriptors after a journal replay.
809 If e2fsck receives an I/O error while replaying the journal, prompt
810 the user whether they want to ignore the error or not; if e2fsck is
811 run in preen mode, force fsck to abort the preen pass.
813 Fix a bug which would cause e2fsck to core dump if the filesystem
814 contains a corrupt extent header, and the user declines to clear the
815 inode. (Addresses Sourceforge Bug: #2791794)
817 Fix e2fsck to restart only once in the case of multiple block groups
818 which inodes in use that are in the uninitialized part of the block
821 To reduce user confusion, if the /etc/mtab file is missing
822 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
823 new, explicit error code to indicate this case. This will cause
824 e2fsck to give a clearer error message when the user is using buggy
825 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
828 Fix e2fsck so that if the primary group descriptors are corrupted, but
829 the backup superblock is entirely invalid, to go back to using (and
830 fixing) the priary group descriptors instead of completely giving up
831 on the filesystem. (Addresses Debian Bug: #516820)
833 Change e2fsck to not abort a preen pass if an inode is found to have
834 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
835 kernels (post 2.6.29) will ignore this field. So let's fix it
836 automatically during the preen pass instead of forcing the user to fix
837 this up manually. (Addresses Debian Bug: #526524)
839 Add resource tracking for e2fsck passes 1b through 1d.
841 Speed up e2fsck by eliminating unnecessary journal checks if the
842 filesystem is already mounted and doesn't need recovery (since the
843 kernel would have run the journal when the filesystem was mounted.)
844 Also speed up e2fsck by avoiding unnecessary block group descriptor
845 updates in ext2fs_close().
847 Add support to chattr to migrate inodes from using direct/indirect
850 Avoid corrupting the filesystem if there is an attempt to shrink a
851 filesystem using resize2fs smaller than posible by making
852 ext2fs_set_bmap() more careful not to delete the old block until the
853 new block can be inserted. In addition, fix a bug in how the minimum
854 size of the filesystem (plus a safety margin) is calculated, and
855 modify resize2fs to refuse to shrink the filesystem below that minimum
856 size without the force flag.
858 Teach blkid to try to figure out DM device names using take advantage
859 of information in sysfs when running on kernels (2.6.29 and later)
860 which provide this information in /sys/block/dm-<N>/dm/name; this is
861 much faster than scanning for the devncie number in /dev/mapper.
863 Fix blkid to prefer /dev/mapper/<name> device names instad of the
864 private /dev/dm-X names.
866 Add an -a option to debugfs's close_filesys command which writes any
867 changes to the superblock or block group descriptors to all of the
868 backup superblock locations.
870 Add support to the filefrag program to use the FIEMAP ioctl.
872 Update Chinese translation from the Translation Project.
874 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
875 Launchpad Bug: #381854)
877 Fixed various Debian packaging issues --- see debian/changelog for
878 details. (Addresses Debian Bug #506064)
884 Add test code to make sure e2fsck's problem.c doesn't have two problem
885 codes assigned to duplicate values.
887 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
888 (Addresses Sourceforge Bug: #2780205)
890 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
891 function declaration for init_resource_track() and
892 print_resource_track() when RESOURCE_TRACK is not defined.
894 The test code which is used to build the tst_csum progam has been
895 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
896 avoid compile problems caused by not having a prototype for
897 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
899 Update the config.guess and config.sub file to the latest from the
900 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
903 Add a new function, ext2fs_extent_open2(), which behaves like
904 pext2fs_extent_open(), but uses the user-supplied inode structure
905 when opening an extent instead of reading the inode from disk.
908 E2fsprogs 1.41.5 (April 23, 2009)
909 =================================
911 Fix a number of filesystem corruption bugs in resize2fs when growing
912 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
915 Debugfs can now set i_file_acl_high via the set_inodes_field command,
916 and print a 64-bit file acl. This is useful for debugging filesystem
917 corruptions where the high bits of i_file_acl_high are set. E2fsck
918 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
919 since some Linux kernel versions pay attention to this field even when
922 Speed up e2fsck when checking clean filesystems by avoiding
923 unnecessary block reads, and coalescing the block group descriptor
924 blocks so they are read using a single read operation.
926 The libuuid library will now close all file descriptors before running
927 uuidd. This avoids problems when the calling program has open sockets
928 which then never get closed because uuidd is a long-running helper
929 daeomn. (Addresses Launchpad bug: #305057)
931 In order to avoid unnecessary full filesystem checks by e2fsck after
932 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
933 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
935 Mke2fs will avoid trying to create the journal when run in
936 superblock-only mode (mke2fs -S), since the left-over journal in the
937 inode table will cause mke2fs to fail.
939 Fix a bug in libext2fs functions that check to see if a particular
940 device or filesystem image is mounted, which would cause these
941 functions to report that a file identical to the (relative) pathname
942 used by a pseudo-filesystem was mounted when in fact it was not.
944 Update Czech translation from the Translation Project.
946 Add Chinese (simplified) translation from the Translation Project.
948 Fix support for external journals (which was broken in e2fsprogs
951 Fix a regression in debugfs where the "stat" command when no
952 filesystem was open would cause debugfs to crash with a segmentation
955 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
956 used to support filesystems without a journal. Update the blkid
957 library so it understands this.
959 The blkid library will remove an entry from the blkid cache
960 representing the entire disk if partitions are found, since presuambly
961 the device previously had no partition table, but has now transitioned
962 to using a partition table.
964 Add a check to mke2fs and tune2fs that the argument to the -m option
965 (which specifies the reserved ratio) must be greater than zero.
966 (Addresses Debian Bug: #517015)
968 Add support for tracking the number kilobytes written to the
969 filesystem via the superblock field s_kbytes_written. It will be
970 updated by the kernel as well as by e2fsprogs programs which write to
971 the filesystem. This is useful for tracking the wear to filesystems
972 on Solid Sstate Drives.
974 Fix compatibility issue in the libext2fs info file and makeinfo
975 version 4.12. (Addresses Red Hat Bugzilla: #481620)
977 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)

994 system-installed blkid implementation via the configure option
998 E2fsprogs 1.41.4 (January 27, 2009)
999 ===================================
1001 Fixed a bug which could sometimes cause blkid to return an exit value
1002 of zero for a non-existent device (Addresses Debian Bug: #502541)
1004 Blkid will now recognize ext3 filesystems that have the test_fs flag
1005 set as ext3 filesystems.
1007 The blkid library will now recognize btrfs filesystems and swap
1008 devices currently used by user-level software suspend.
1010 Tune2fs now updates the block group checksums when changing the UUID
1011 to avoid causing e2fsck to complain vociferously at the next reboot.
1013 Tune2fs's inode size resizing algorithms have been fixed so it is not
1014 vastly inefficient for moderate-to-large filesystems, due to some
1015 O(n**2) and O(n*m) algorithms that didn't scale well at all.
1017 Fix tune2fs's inode resizing algorithm so it will not corrupt
1018 filesystems laid out for RAID filesystems; in addition, tune2fs will
1019 refuse to change the inode size for filesystems that have the flex_bg
1020 feature enabled. (This is a limitation in the current implementation
1023 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1024 filesystems with 32-bit block numbers, when the headers for 64-bit
1025 block numbers was added. This regression has been fixed.
1027 Debugfs's ncheck command has been fixed to avoid printing garbage
1028 characters at the end of file names.
1030 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
1031 when shrinking filesystems with uninit_bg feature would not be moved.
1032 In addition, blocks and inode table blocks were not being correctly
1033 freed when shrinking filesystems with the flex_bg feable, which caused
1034 resize2fs -M to fail. Finally, when blocks are moved, make sure the
1035 uninitialized flag in extents is preserved.
1037 Fix bug which caused dumpe2fs to abort with an error if run on a
1038 filesystem that contained an external journal.
1040 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1041 for this in argv[0] to provide better legacy support for these
1042 distributions. This is a practice that should NOT be continued,
1045 Mke2fs now has a new option -U, which allows the user to specify the
1046 UUID that should be used for the new filesystem.
1048 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1049 minus one block. This allows users who have read that ext3 supports
1050 up to 16TB filesystems and who create a 16TB LVM to not get confused,
1051 since the true limit is really 16TB minus one block.
1053 E2fsck will no longer abort an fsck run if block group has an errant
1056 E2fsck now distinguishes between fragmented directories and fragmented
1057 files in verbose mode statistics and in the fragcheck report.
1059 Fix a bug in e2fsck which casued it double count non-contiguous
1060 extent-based inodes.
1062 E2fsck will leave some slack space when repacking directories to allow
1063 room for a few directory entries to be added without causing leaf
1064 nodes to be split right away.
1066 Fix a bug which caused e2fsck to crash when it comes across a
1067 corrupted interior node in an extent tree with the error message:
1068 "Error1: Corrupt extent header on inode XXXXXX"
1070 E2fsck problem descriptions involving the journal are no longer
1071 referred to as "ext3" problems, since ext4 filesystems also have
1074 Fix a long-standing bug in e2fsck which would cause it to crash when
1075 replying journals for filesystems with block sizes greater than 8k.
1077 Update Catalan translation from the Translation Project.
1079 Fixed various Debian packaging issues --- see debian/changelog for
1080 details. (Addresses Debian Bugs: #503057, #502323, #511207)
1085 Fix build of e2fsck.profiled, and add support for building profiled
1086 binaries in the misc directory if configured with --enable-profile.
1088 The ext2fs_open() function now performs more sanity checks on the
1089 superblock to avoid potential divide by zero errors by other parts of
1092 The ext2fs_read_inode_full() function now has a safety check to avoid
1093 a segmentation fault on corrupted filesystems.
1095 The ext2fs_new_inode() function now has a sanity check so that if the
1096 s_first_inode field in the superblock is insane, it will return
1097 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1099 To avoid segmentation faults, ext2fs_block_alloc_stats() and
1100 ext2fs_inode_alloc_stats() now validates the passed inode or block
1101 number to avoid overrunning an array boundary.
1103 Various signed/unsigned errors for variables containing block numbers
1106 Accomodations for gcc's stupidity in not realizing that constant
1107 strings that do not contain a '%' character are safe to use in format
1108 strings have been made so that distributions that want to compile
1109 e2fsprogs with -Werror=format-security have an easier time doing so.
1111 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1113 Added the utility make-sparse.c to the contrib directory.
1115 The ext2fs_block_iterate2() function now reflects errors from
1116 ext2fs_extent_set_bmap() to the caller, if the callback tries to
1117 change a block on an extent-based file, and ext2fs_extent_set_bmap()
1118 fails for some reason (for example, there isn't enough disk space to
1119 split a node and expand the extent tree.
1121 The ext2fs_block_iterate2() function will preserve the uninit flag in
1122 extents when the callback function modifies a block in an extent-based
1125 E2fsck will now flag filesystems that have an insane s_first_ino field
1126 in their superblock, and attempt to use a backup superblock to repair

1131 ===================================
1133 E2fsck has been fixed so it prints the correct inode number for
1134 uinit_bg related problems.
1136 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1137 is available on linux. This can be disabled via a configuration
1138 option in /etc/e2fsck.conf.
1140 Fix a file descriptor leak in libblkid when checking to see if an ext4
1141 or ext4dev module exists.
1143 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1144 while trying to close a filesystem can lead to infinite loops.

1151 Add a check in the Unix I/O functions in libext2fs so that when a
1152 device is opened read/write, return an error if the device is
1153 read-only using the BLKROGET ioctl.
1155 Fix debugfs's ncheck command so that it prints all of the names of
1156 hardlinks in the same directory.
1158 Fix a bug in libblkid so it correctly detects whether the ext4 and
1159 ext4dev filesystems are available, so that the ext4dev->ext4
1160 fallback code works correctly.

1166 trying to build the lib/et directory. (Addresses Sourceforge Bug:
1169 Updated "make depend" information for crc16.o
1172 E2fsprogs 1.41.2 (October 2, 2008)
1173 ==================================
1175 Fix e2fsck's automatic blocksize detection. This fixes a regression
1176 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1177 specifies a block number using the -b option if the blocksize option
1178 isn't also specified using -B. Unfortunately, users very commonly
1179 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1180 superblock; in fack e2fsck will often suggest this kind of command
1183 Enhance the debugfs's "ncheck" command so it will print all of the
1184 pathnames for the specified inodes. (Previously, in some cases ncheck
1185 might not print a pathname for an inode at all if some of the other
1186 inodes had multiple hard links.)
1188 Enhance debugfs's "hash" command so the hash seed can be specified via
1189 a command-line option. In addition, allow the hash algorithm to be
1190 specified by name instead of just by number.
1192 Fix e2fsck so that we don't accidentally print the translation file's
1193 header when asking the user a custom question so there is no prompt
1194 defined for a particular problem record. For example, the question
1195 "Run journal anyway" will get the PO header tacked on because e2fsck
1196 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1247 libraries when using ELF shared libraries.
1249 Fix ELF shared library when building on systems that don't already

1251 Sourceforge Bug: #2088537)
1253 Fix the pkg-config files so they work correctly when linking with
1254 static libraries and fix the include directory so programs don't have
1255 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
1256 instead. (Addresses Sourceforge Bug: #2089537)
1258 Make sure ext2fs_swab64() is compiled for all platforms, and not just
1259 for x86. (Addresses Debian Bug: #497515)
1261 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1262 non-x86 platforms. (They had been removed for x86 earlier.)
1264 Fix diet libc compilation support, which had bitrotted due to lack of

1277 E2fsprogs 1.41.1 (September 1, 2008)
1278 ====================================
1280 Many people are forgetting to update their mke2fs.conf file, and this
1281 causes ext3, ext4, and ext4dev filesystems won't get created with the
1282 proper features enabled. We address this in two ways. First, mke2fs
1283 will issue a warning if there is not definition for an ext3, ext4, or
1284 ext4dev filesystem and the user is trying to create such a filesystem
1285 type. Secondly, when installing from a source build, "make install"
1286 will provide basic configuration file handling for /etc/mke2fs.conf.
1287 If it exists, and does not mention ext4dev, it will be moved aside to
1288 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1289 be installed. If the existing /etc/mke2fs.conf file does mention
1290 ext4dev, then "make install" will install official mke2fs.conf file as
1291 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1292 they should look to see if any changes need to be merged.
1294 The mke2fs program will now create the journal in the middle of the
1295 filesystem, since this minimizes seek times on average for fsync-heavy
1296 workloads. In addition, mke2fs will now create journals using extents
1297 for filesystems that support them. This results in a more efficient
1298 encoding for the journal since it eliminates the need for using
1301 The mke2fs program will avoid allocating an extra block to the
1302 journal. (Addresses Sourceforge Bug: #1483791)
1304 Mke2fs will correctly enforce the prohibition against features
1305 (specifically read-only features) in revision 0 filesystems. (Thanks
1306 to Benno Schulenberg for noticing this problem.)
1308 Mke2fs previously would occasionaly create some slightly non-optimally
1309 placed inode tables; this bug has been fixed.
1311 The mke2fs and tune2fs programs now print the correct usage message
1312 describing the maximum journal size. (Addresses Debian Bug: #491620)
1314 Add support for setting the default hash algorithm used in b-tree
1315 directories in tune2fs (from a command-line option) or mke2fs (via
1316 mke2fs.conf). In addition, change the default hash algorithm to
1317 half_md4, since it is faster and better.
1319 The blkid library will now recognize MacOS hfsx filesystems, and
1320 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1321 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1323 The blkid library has improved detection of JFS and HPFS filesystems.
1324 (Addresses Launchpad Bug: #255255)
1326 The blkid library is now much more efficiently handling devicemapper
1327 devices, mainly by no longer using the devicemapper library. This can
1328 speed up access for systems with a large number of device mapper
1331 Blkid had a number of cache validation bugs in libblkid that have been
1332 fixed. (Addresses Debian Bug: #493216)
1334 Resize2fs will now properly close out the "updating inode references"
1335 progress bar so there is a newline printed before printing the final
1336 "resize is successful" message.
1338 Resize2fs will now correctly handle filesystems with extents and/o
1339 uninitialized block groups correctly when file/directory blocks need
1340 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1341 is not present). To support this, the ext2fs library now supports
1342 initializing inode and block bitmaps that are not yet initialized when
1343 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1344 addition, e2fs_block_iterate2() can now support changing the location
1345 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1346 been optimized to avoid creating unnecessary new extents when updating
1347 the location of blocks in the extent tree. This will also help out
1348 e2fsck's recovery of obscurely corrupted filesystems with extents,
1349 when blocks are claimed by multiple inodes.
1351 Add support for on-line resizing ext4 filesystem with the flex_bg
1352 filesystem feature. The method for doing so is not optimal, but to do
1353 a better job will require kernel support.
1355 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1356 debugfs programs to not be able to read e2image files; the signed
1357 vs. unsigned bug in the code which read bitmaps from the e2image has
1358 been fixed. (Addresses Debian Bug: #495830)
1360 Resize2fs is now correctly managing the directory in-use counts when
1361 shrinking filesystems and directory inodes needed to be moved from one
1362 block group to another. This bug has been around since e2fsprogs
1363 1.26, and is largely harmless, but does cause a filesystem corruption
1364 which will be flagged by e2fsck after the filesystem has been shrunk.
1366 E2fsck will no longer issue spurious complaints about the inode size
1367 caused by very large extent-based files, and by blocks reallocated
1368 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1369 Kernel Bugzilla: #11341)
1371 Mke2fs will now set the creation timestamp on the lost+found directory
1372 and the root directory. (More generally, all new inodes created using
1373 the ext2fs library will correctly set the creation timestamp.)
1375 E2fsck now correctly calculates ind/dind/tind statistics in the
1376 presence of extent-based files. In addition, "e2fsck -v" will report
1377 statistics of the depth of extent trees in the filesystem. E2fsck can
1378 also give an inode fragmentation report using "e2fsck -E fragcheck"
1379 which can be useful when debugging the kernel block allocation
1382 Fix support for empty directory blocks in ext4 filesystems with 64k
1383 blocksize filesystems.
1385 E2fsck will now print the depth of corrupt htree directories.
1387 Debugfs's htree command now correctly understands extent-based
1388 directories. It will also print out the minor hash as well as the
1391 Debugfs has a new command which will print the supported features of
1392 e2fsprogs, to enable scripts to know whether the installed version of
1393 e2fsprogs can support a specific feature.
1395 Debugfs will now write files using extents for filesystems that
1398 The error message printed by "tune2fs -I" if the inode size was too
1399 small was rather confusing, so it has been improved. Also, we won't
1400 try to create an undo log until we know that command-line-specified
1401 parameters such as "tune2fs -I <inode size>" are valid.
1403 Given some filesystems found "in the wild" that had non-zero block
1404 group checksums even though the uninit_bg/gdt_sum feature was not
1405 enabled, e2fsck would issue spurious error messages. Teach
1406 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1407 entirely if the feature flag is not set. (Addresses Debian Bug:
1410 The blkid program will now print out a user-friendly listing of all of
1411 the block devices in the system and what they contain when given the
1412 -L option. (Addresses Debian Bug: #490527)
1414 The filefrag program now has a more accurate calculation for the
1415 number of ideal extents. (Addresses Debian Bug: #458306)
1417 The test I/O manager is now enabled by default, but its overhead is
1418 only incurred when it would be enabled via the TEST_IO_FLAGS or
1419 TEST_IO_BLOCK environment variables.
1421 Typographical errors in various program strings and usage messages
1422 have been fixed; most of these were pointed out by the e2fsprogs
1423 message catalog translators. (Thanks, translators!)

1448 Sourceforge Bug: #2019287)
1450 The ext2fs_extent_set_bmap() had some bugs when setting the first
1451 block in a file, or when replacing a single block extent. Those cases
1452 fortunately were came up relatively rarely when e2fsck was checking
1453 files, but caused some problems when resize2fs was shrinking

1464 Ext2ed was failing to build because masix support had been removed in
1465 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
1467 The configure script now respects the LDFLAGS environment variable if
1468 it is set when configure is called. (Addresses Sourceforge Feature
1471 Libuuid is now more portable to the Windows platform. (Addresses
1472 Sourceforge Feature Request: #1937287)
1474 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1475 bare echo commands so that configure flags such as --quiet work
1476 correctly. (Addresses Sourceforge Patches: #2058794)
1478 A few uses of sprintf have been removed from the ext2fs library to
1479 make life easier for bootloaders with a limited libc environment.
1480 (Addresses Sourceforge Bug: #2049120)
1482 The ext2fs_read_inode() checks the validity of the inode number passed
1483 to it earlier, to avoid doing some needless work when it would fail

1487 passed to it earlier, to avoid doing some needless work when it would
1490 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1491 top-level Makefile. That automatic rule is used to better support
1492 SCCS, but it caused problems for a particular niche distribution which
1493 likes to use configure.sh files to store the configure options used to
1494 build a package. Unfortuntaely GNU make will use the configure.sh to
1495 replace the configure script, resulting in a self-inflicted fork bomb
1496 leading to an out-of-memory crash.
1498 To support old GNU C compilers don't use C99/C++ comments, but only
1499 K&R style comments, and don't try to use __builtin_expect if __GNUC__
1500 is less than 3. (__builtin_expect is only supported for gcc versions
1501 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1502 this is an optimization, we only try to use __builtin_expect for gcc 3
1505 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
1506 __LITTLE_ENDIAN, which are only defined by glibc's header files and
1507 hence isn't portable.
1509 For the convenience for some distributions that need a static tune2fs,
1510 the Makefile for misc/ now has a tune2fs.static target.
1512 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1513 for extent-based files
1515 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1518 All source files no longer have any trailing white space.
1520 The io_channel_read_blk64() and io_channel_write_blk64() functions are
1521 now functions instead of C preprocessor macros to provide better
1522 forward compatibility.
1524 The e2fpsrogs translation template now expands the @x abbrevation.
1526 Various namespace leackages in libblkid, libe2p, and libext2fs have
1529 Fix a parallel build problem in e2fsprogs.
1531 E2fsprogs is now more portable to Solaris.
1532 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
1534 * Scripts do not assume that /bin/true is always in /bin
1535 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
1536 * Flush stdio handles before calling setbuf(), since Solaris will
1537 discard any pending output to the stream.
1538 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
1539 picky about which C compiler can beused for SUSv3 conformance.
1540 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
1541 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
1542 Since we need some SUSv3 functions, consistently use SUSv3 so
1543 that e2fsprogs will build on Solaris using c99.
1544 * Solaris C99 does not support varargs C preprocessor macros
1545 * Solaris header files pollute the C namespace if in/netinet.h
1546 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
1548 * Solaris ships with a pathetically ancient shell in /bin/sh so we
1549 avoid the use of various more avanced shell constructs such as $().
1551 The "make rpm" command will now take some extra configure optiosn from
1552 the build environment without needing to patch the source tree.
1554 The ext2fs_add_dir_block() function will now grow the dblist more
1555 aggressively as an optimization to avoid copying the array too often.
1557 The e2fsck_write_bitmaps() will write the block and inode bitmaps
1558 together instead of in two passes.
1561 E2fsprogs 1.41 (July 10, 2008)
1562 ==============================
1564 Add support for ext4 filesystem features, in particular extents,
1565 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
1566 support for checking journal checksums. Debugfs will print new
1567 superblock and inode fields that were defined for ext4. For example,
1568 the nanosecond and i_version fields of an inode, and the
1569 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1570 Note: Resize2fs doesn't currently support the combination of flex_bg
1571 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
1573 Tune2fs can support migrating a filesystem from using 128 byte inodes
1574 to 256 byte inodes, so it can take advantage of the full features of
1577 Add support for "undo" support. E2fsck and mke2fs can optionally
1578 record an undo log which can replayed by the program e2undo.
1580 E2fsck could damage a filesystem by trying to relocate inode tables
1581 due to corrupted block group descriptors, where the attempted inode
1582 table relocation would do far more harm than good. E2fsck has been
1583 fixed to detect this these sorts of corrupted block group descriptors
1584 much earlier in e2fsck processing, so it can try to use the backup
1585 superblock and block group descriptors first. This should be a much
1586 better strategy for recovering these types of corrupted filesystems.
1587 (Addresses Sourceforge Bug: #1840291)
1589 E2fsck will display a more understandable message when the last check
1590 field in the superblock is in the future. (Addresses Debian Bug:
1593 E2fsck now performs more extensive and careful checks of extended
1594 attributes stored in the inode.
1596 Enhance mke2fs to print a more explanatory error message when
1597 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
1600 Fix mke2fs to use a default block size of 4k when formatting an
1601 external journal device. This is done by using a fixed filesystem
1602 type list that consists only of the single filesystem type "journal"
1603 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
1604 Debian Bug: #488663)
1606 Speed up how mke2fs writes the journal data blocks by writing the disk
1607 blocks in larger chunks.
1609 Fix blkid handling of stale devices. Fix a bug which could cause a
1610 core dump while garbage collecting the blkid cache, and assure that
1611 blkid_find_dev_with_tag() never returns a non-existent device. Also,
1612 if a filesystem is found at a new /dev location, eliminate any
1613 duplicate stale entries which can not be verified.
1614 (Addresses Debian Bugs: #487758, #487783)
1616 Add more paranoid checks for LVM volumes and swap partitions in
1617 blkid's probe function, to reduce the chances of false positives.
1619 The mke2fs program now has a much more sophisticated system for
1620 controlling configuration parameters of a newly created filesystem
1621 based on a split filesystem and usage type system. The -t option to
1622 mke2fs was a deprecated alias to -c; it now specifies a filesystem
1623 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1624 separated usage list. The filesystem type information and type
1625 information is used to extract configuration parameters from the
1626 /etc/mke2fs.conf file.
1628 The mke2fs program will no longer complain and request the -f option
1629 when the user tries to create a filesystem with greater than 2**31
1632 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1633 adjust the mke2fs.conf file so filesystems for the Hurd are created
1634 with a blocksize of 4096 and inode size of 128, which is all it knows
1635 how to handle. (Addresses Debian Bug: #471977)
1637 Mke2fs will always make sure that lost+found always has at least 2
1638 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1640 Resize2fs will now print the minimum needed filesystem size if given
1641 the -P option, and will resize the filesystem to the smallest possible
1642 size if given the -M option.
1644 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1645 blocks are consumed during an off-line resize.
1647 The "ls" command in debugfs now supports the -p option, which causes
1648 it to quote the filenames so that spaces or tabs in directory entries
1649 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses

1659 Fix a bug in badblocks which caused it to overrun an array and likely
1660 crash if more than 8 test patterns are specified using the -t option.
1661 (Addresses Debian Bug: #487298)
1663 Add support to badblocks to limit how quickly it reads from the disk
1664 drive (so it can be used for background scrubbing), and so it will
1665 abort after finding a given number of errors.
1667 Remove support for the legacy big-endian filesystem format which only
1668 existed on extremely long-dead PowerPC kernels almost a decade ago.
1670 Remove MASIX support from e2fsprogs.

1709 mkswap that don't support the -U option.
1711 A few library routines have been converted to support 64-bit block
1712 numbers; in particular, the I/O manager functions, the test_io,
1713 inode_io, and unix_io managers have all be converted to support 64-bit
1716 Debugfs can now be extended for use by test programs. See
1717 lib/ext2fs/extents.c for an example for how it can be used. The test
1718 program links against the debugfs object files, and provides
1719 additional commands by defining an auxiliary libss command table.
1721 The lazy_bg filesystem feature, which was only used by developer's
1722 testing, has been removed since it has been largely supplanted by
1723 uninit_bg. This also simplifies the code.

1754 E2fsprogs 1.40.10 (May 21, 2008)
1755 ================================
1757 When deciding whether or not to revalidate a blkid cache entry, if the
1758 device's mtime is newer than the last time the cached entry was
1759 validated, force a revalidation.
1761 Fix a potential data corruption bug in e2fsck in the journal replay.
1762 The chances of this is happening is extremely remote, especially the
1763 default data=ordered or data=writeback modes. However, if a block
1764 which has been journalled starts with the first four bytes 0xc03b3998,
1765 when e2fsck replays the journal, those four bytes will be replaced
1766 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1767 metadata to begin with those fatal 4 byte sequence, and unless
1768 data=ordered mode is in use, data blocks are never journaled.
1770 Updated German, Dutch, Sweedish, and Vietnamese translations.
1775 Fixed various Debian packaging issues --- see debian/changelog for
1778 Remove default sizes of types when cross compiling, since autoconf

1782 E2fsprogs 1.40.9 (April 27, 2008)
1783 =================================
1785 SuSE's security team audited uuidd and came up with a few minor
1786 issues. None of them are serious given that uuidd runs setuid as a

1790 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1791 work correctly with in-inode extended attributes.

1807 Fix fsck so that progress information is sent back correctly when
1808 multiple filesystems are being check and the output of fsck is being
1809 redirected to a file descriptor. Also, include the device name (w/o
1810 spaces) in the progress information sent back via a file descriptor.

1852 E2fsprogs 1.40.8 (March 13, 2008)
1853 =================================
1855 Fixed e2image -I so it works on image files which are larger than 2GB.
1857 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1858 the size is larger than the number of blocks found in the inode, don't
1859 try to allocate extra empty blocks at the end of the directory to make
1860 up the difference; there's no point to doing that. In addition, if
1861 the size is not a multiple of a blocksize, always fix it.
1863 E2fsck handled a pass 2 "should never happen error" by not giving
1864 enough information and then core dumping. Unfortunately, it was all
1865 too easy to trigger the "should never happen" situation if a
1866 directory's inode size was not correct. This has been fixed, but
1867 e2fsck has also been taught how to handle this situation more
1868 gracefully, by simply removing the inode hash tree information, so
1869 that it can be rebuilt again after e2fsck's pass 3. (Addresses
1870 Launchpad Bug: #129395)
1872 Resize2fs had a bug resizing large inodes with extended attributes
1873 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1874 completely on big-endian systems such as PowerPC. The bug should be
1875 completely fixed now. Yay for regression test suites. (Addresses Red
1876 Hat Bugzilla: #434893)
1878 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
1879 translations. Many thanks to Philipp Thomas from Novell for stepping
1880 up to become the new German translation maintainer! (Addresses Debian

1884 make it clear that it is just clearing the HTREE information, not the

1892 Add new functions, ext2fs_dblist_get_last() and
1893 ext2fs_dblist_drop_last(), which allows the caller to examine the last
1894 directory block entry added to the list, and to drop if it necessary.
1896 Fixed a portability problem in libblkid with DJGPP.
1898 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
1899 to Philipp Thomas for pointing this out.

1902 fail with an error code.
1905 E2fsprogs 1.40.7 (February 28, 2008)
1906 ====================================
1908 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1909 depreciate the -s option, since it can result in filesystems which
1910 e2fsck can't fix easily. There are very good reasons for wanting to
1911 disable sparse_super; users who wants to turn off sparse_super can use
1912 debugfs. (Addresses Sourceforge Bug: #1840286)
1914 Add missing options to mke2fs's usage message. (Addresses Sourceforge
1917 Fix bug in resize2fs when large (greater than 128 byte) inodes are
1918 moved when a filesystem is shrunk; it was only moving the first 128
1919 bytes, so extended attributes were not getting moved. (Addresses Red
1920 Hat Bugzilla: #434893)
1922 E2fsck now prints an explicit message when the bad block inode is
1923 updated, to avoid confusion about why the filesystem was modified.
1924 (Addresses Sourceforge Bug: #756460)
1926 Allow mke2fs and tune2fs manipulate the large_file feature.
1927 Previously we just let the kernel and e2fsck do this automatically,
1928 but e2fsck will no longer automatically clear the large_file feature.
1929 It still isn't really necessary to worry about this feature flag
1930 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
1933 Suppress message about an old-style fstab if the fstab file is empty.

1937 reporting a free block more than once if there are too few free blocks
1938 in the filesystem. (Addresses Sourceforge Bug: #1096315)
1940 Change e2fsck to no longer clear the LARGE_FILES feature flag
1941 automatically, when there are no more > 2GB files in the filesystem.
1942 It's been almost a decade since there have been kernels that don't
1943 support this flag, and e2fsck clears it quietly without telling the
1944 user why the filesystem has been changed.
1946 Fix bug which could cause libblkid to seg fault if a device mapper
1947 volume disappears while it is being probed. (Addresses RedHat
1950 Inhance e2fsck's reporting of unsupported filesystem feature flags.

1953 Fix option syntax in dumpe2fs for explicit superblock and blocksize
1954 parameters. What was currently documented in the man page has been
1955 broken for some time, due to getopt() implementation changes. The
1956 option sytax has been changed to one which is can be more portable
1957 supported and which is consistent with the format for extended options

1996 partially filled-in filesystem object on an error, so that e2fsck can
1997 print more intelligent error messages.
1999 Add a new function e2p_edit_feature2() which allows the caller to
2000 specify which feature flags are OK to set or clear, and which returns

2065 ===================================
2067 Fix a potential overflow big in e2image if the device name is too
2070 Mke2fs will now create new filesystems with 256 byte inodes and the
2071 ext_attr feature flag by default. This allows for much better future
2072 compatibity with ext4 and speeds up extended attributes even on ext3
2075 Teach e2fsck to ignore certain "safe" filesystem features which are
2076 set automatically by the kernel. Having the kernel set features
2077 automagically behind the user's back is a bad idea, and we should try
2078 to break the kernel of this habit, especially for the newer ext4
2079 feature flags. But for now, we will try to avoid needless full checks
2080 which can annoy users who are doing fresh installs.
2082 Add support in tune2fs and mke2fs for making a filesystem as being "ok
2083 to be used with test kernel code". This will be needed for using test
2084 filesystems with the latest ext4 kernel code.

2087 numbers instead of by name, since that optimizes performances much
2088 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
2090 If e2image fills the disk, fix it so it exits right away instead of
2091 spewing large numbers of error messages.

2094 If ftruncate64() is not available for resize2fs, let it use ftrucate()
2095 instead, but have it check to see if the size would get truncated, and
2096 skip calling ftruncate in that case.
2098 Add support for detecting HFS+ filesystems in the blkid library.
2100 Add supprt in the blkid library for ext4/ext4dev filesystems.
2102 Fix a bug in blkid where it could die on a floating point exception

2156 Improve time-based UUID generation. A new daemon uuidd, is started
2157 automatically by libuuid if necessary. This daemon is setuid to allow
2158 updates to /var/lib/libuuid, so the clock sequence number can be

2160 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
2163 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2164 superblocks. This avoids e2fsck from concluding that a full
2165 filesystem check is required before backing up the superblock due to
2166 changes in the feature flags. (Addresses Debian Bug: #454926)
2168 Fix fsck to only treat the '#' character as a comment at the beginning
2169 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

2209 ===================================
2211 Fix a potential security vulnerability where an untrusted filesystem
2212 can be corrupted in such a way that a program using libext2fs will
2213 allocate a buffer which is far too small. This can lead to either a
2214 crash or potentially a heap-based buffer overflow crash. No known
2215 exploits exist, but main concern is where an untrusted user who
2216 possesses privileged access in a guest Xen environment could corrupt a
2217 filesystem which is then accessed by the pygrub program, running as
2218 root in the dom0 host environment, thus allowing the untrusted user to
2219 gain privileged access in the host OS. Thanks to the McAfee AVERT
2220 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2222 Fix hueristics in blkid which could cause a disk without partitions to
2223 be incorrectly skipped when a loopback device is present. (Addresses
2224 Red Hat Bugzilla #400321.)
2226 Fix e2image so that in raw mode it does not create an image file which
2227 is one byte too large.
2229 Change mke2fs's usage message so it recommends the preferred -E option
2230 instead of the deprecated -R option.
2232 Enhance the blkid library so it will recognize squashfs filesystems.
2233 (Addresses Red Hat Bugzilla #305151.)
2235 Enhance e2fsck so it will force the backup superblocks to be backed up
2236 if the filesystem is consistent and key constants have been changed

2240 Enhance blkid's detection of FAT filesystems; so that USB disks with
2241 only a single bootable partition will not get missed.
2243 E2fsck will no longer mark a filesystem as invalid if it has time
2244 errors (i.e., if superblock mount time or last write time is in the
2245 future) and the user refuses to fix the problem.
2247 The Ubuntu init scripts don't properly set the system time correctly
2248 from hardware clock if the hardware clock is configured to tick local
2249 time instead of GMT time. Work around this as best as we can by
2250 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2251 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2254 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2255 Hat Bugzilla #151533.)
2257 Fix e2fsck so that if the superblock is corrupt, but still looks
2258 vaguely like an ext2/3/4 superblock, that it automatically tries to
2259 fall back to the backup superblock, instead of failing with a hard
2262 Make the e2fsprogs program more robust so that they will not crash
2263 when opening a corrupt filesystem where s_inode_size is zero.
2265 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2266 arguments are detected as such and the parse error is reported to the
2267 user. (Addresses Debian Bug #435381.)
2269 Change e2fsck so it will not complain if a file has blocks reallocated
2270 up to the next multiple of a system's page size.
2272 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2273 about (valid) filesystems where the inode table extends to the last
2274 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2276 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2277 allocating inode tables for some relatively rare odd disk sizes.

2280 Add Catalan translation and update Dutch and Swedish translations
2281 from the Translation Project.
2283 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2284 still had an issue when trying to figure out whether we need to
2285 byte-swap fast symlinks that contained extended attributes.
2287 Fixed spelling mistakes, typos, and otherwise clarified man pages.

2299 works correctly when the prefix is not the root directory.
2301 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2302 clena up after themselves by deleting the test.img temporary file
2303 after completing the test.
2305 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2306 first directory entry in a directory block and the last directory
2307 entry in the previous directory block is not in use. Fortunately
2308 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2309 places where it is extremely unlikely to run into this corner case.
2311 Fix missing dependency which would cuase parallel builds to fail.
2312 (Addresses Sourceforge Bug #1842331.)
2314 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2315 calling open(O_CREATE) with a missing mode parameter.

2322 are properly passed back up through the call stack.
2324 E2fsprogs 1.40.2 (July 12, 2007)
2325 ================================
2327 A recent change to e2fsck_add_dir_info() to use tdb files to check
2328 filesystems with a very large number of filesystems had a typo which
2329 caused us to resize the wrong data structure. This would cause a
2330 array overrun leading to malloc pointer corruptions and segfaults.
2331 Since we normally can very accurately predict how big the the dirinfo
2332 array needs to be, this bug only got triggered on very badly corrupted
2335 Fix a bug in e2fsck which caused it to incorrectly salvange
2336 directories when the last entry's rec_len is bogusly too big. This
2337 resulted in a nonsense filesystem corruption to be reported, and
2338 required a second run of e2fsck to fully fix up the directory.

2343 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2347 E2fsprogs 1.40.1 (July 7, 2007)
2348 ===============================
2350 Fix bug which could cause libblkid to loop forever. When revalidating
2351 a partition where there is obsolete information in /etc/blkid.tab, we
2352 end up freeing a the type tag without clearing dev->bid_type, causing
2353 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2355 The Turkish translation has a bug in it where it has the translation
2356 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2357 @E, recursively, forever, until the stack fills up and e2fsck core
2358 dumps. We fix this by making e2fsck stop @-expansions after a
2359 recursive depth of 10, which is far more than we need.
2360 (Addresses Sourceforge Bug: #1646081)
2362 Compile the default mke2fs.conf into mke2fs program. People are
2363 getting surprised by mke2fs creating filesystems with different
2364 defaults than earlier versions of mke2fs if mke2fs.conf is not
2365 present. So we now create a built in version of mke2fs.conf file
2366 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2367 (Addresses SourceforgeBug: #1745818)
2369 Improve the config/parse_types.sh helper script. Fix a potential
2370 security problem if e2fsprogs is built as root (as Gentoo does!). In
2371 addition fix the script and how it is called from the configure script
2372 so that it does the right thing when cross-compiling. (Fixes Gentoo
2375 Update Vietnamese, French, and Dutch PO files from the Translation
2376 Project. Also created a new e2fsprogs.pot file for translator.
2378 Fix bogus strip permission errors when building under Debian. When
2379 building the e2fsprogs dpkg's, the dh_strip command emits a large
2380 number of error messages caused by the permissions not being right.
2381 So run dh_fixperms before running dh_strip.
2386 Add new function: profile_set_default(). This function sets the value
2387 of the pseudo file "<default>". If the file "<default>" had
2388 previously been passed to profile_init(), then def_string parameter
2389 will be parsed and used as the profile information for the "<default>"
2392 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2393 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2394 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2396 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2397 priority" environment variable that overrides all others, where as
2398 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2399 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2400 the all the rest are set. This will assure that the locale when
2401 running the test suites is the "C" locale. (Obviates Gentoo patch:

2410 Add new blkid -g option which causes the blkid cache to be garbage
2413 Fix a bug in libblkid which could cause the internal field bid_type to
2414 become corrupted. Fortunately bid_type isn't used much, and bid_label
2415 and bid_uuid is only used by debugging code, so the impact of this bug

2419 created with a requested RAID stride, and then use it automatically in
2422 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2423 isn't too big. In some cases Lustre users have tried specifying an
2424 inode size of 4096 bytes, while keeping an inode ratio of one inode

2428 superblock, so that it won't accidentally find a superblock that was
2429 located in the journal, and then later reject it as being not a valid
2432 Fix e2fsck get_size logic so that it will work with the Linux floppy
2433 driver. The Linux floppy driver is a bit different from the other
2434 block device drivers, in that if the device has been opened with
2435 O_EXCL, it disallows another open(), even if the second open() does
2436 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2438 Fix error checking of badblock's last-block and start-block arguments.

2457 Fix e2fsck so that it updates the journal inode if it is corrupted and
2458 the backup journal information from the superblock was successfully
2459 used to recover the filesystem.
2461 Fix e2fsck so that it checks all of the blocks in the journal inode
2462 for validity. The original code only checked the direct blocks to
2463 make sure the journal inode was sane. Unfortunately, if some or all
2464 of the indirect or doubly indirect blocks were corrupted, this would

2469 Add extra sanity checks for extended attributes in the case where the
2470 size is zero but the offset is very large.

2476 the top-level COPYING file (Red Hat Bugzilla: 166058)
2478 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
2480 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
2482 Remove check in e2fsck which requires EA's in inodes to be sorted;
2483 they don't need to be sorted, and e2fsck was previously wrongly
2484 clearing unsorted EA's stored in the inode structure.
2486 Allow mke2fs or tune2fs to create a substantially larger journal (up
2487 to 10,240,000 blocks).
2489 Fix MD superblock detection, and make sure the correct UUID is
2490 reported from the MD superblock.
2492 Fix a signed vs. unsigned bug in debugfs.
2494 Enhance debugfs's date parser so that it accepts integer values.
2496 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
2497 file with multiply claimed blocks is hard linked. or not at all if the
2498 root directory contains shared blocks
2500 Enhance debugfs so it can modify the block group descriptors using the
2501 command set_block_group_descriptor.

2525 field on the first pass.
2527 Fix e2fsck to set the file type of the '..' entry when connecting
2528 a directory to lost+found. (Addresses Lustre Bug: #11645)
2530 Enhance e2fsck to recover directories whose modes field were corrupted
2531 to look like special files. This is probably only useful in
2532 artificial test cases, but it will be useful if we ever do the "inodes
2533 in directory" idea for ext4.
2535 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
2538 Fix resize2fs parsing of size parameter (in sector units). This was
2539 actually a bug in libe2p's parse_num_blocks() function. When handling
2540 the 's' suffix, it was ignoring the blocksize information passed in
2541 from the caller and always interpreting the number in terms of a 1k
2542 blocksize. (Addresses Debian Bug: #408298)

2561 Allow debugfs and dumpe2fs to support fs features under development.
2563 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2564 ext2fs_open() , which allows application to open filesystes with features
2565 which are currently only partially supported by e2fsprogs.
2567 Allow unix_io to support offsets greater than 2G (Addresses

2601 displayed as "ec" instead of "ffffffec".
2603 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
2605 Device mapper scanning wasn't working in the blkid library because the
2606 pathnames had an extra "/dev" when they were being probed.
2608 Add GFS/GFS2 support to the blkid library.
2610 Fix blkid support of empty FAT filesystem labels.
2612 Avoid recursing forever (or for a long time) when the blkid library
2613 searches for a device and there are symlinks to directories in /dev.

2631 translation. (Addresses Debian bug: #411562)
2633 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2634 determining a partition's size, since binary searching to determine
2635 the device doesn't work on FreeBSD.
2637 Documentation about UUID's is available in enough places, and it's
2638 awkward to deal with debian-legal's insanities. So I'm caving in the
2639 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2640 don't have do the dfsg tarball. Also remove the rule that only tried
2641 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2642 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)

2673 Set local environment variables to C so mk_cmds and compile_et always
2674 work. (Addresses SourceForge Bug: #1532177)
2676 Added the 64-bit byte swapping function ext2fs_swab64().
2678 Added two new helper functions to prevent 2**31/2**32-1 overflow
2679 problems: ext2fs_div_ceil() and e2p_percent().
2681 Create new ext2fs library inline functions ext2fs_group_first_block()
2682 and ext2fs_group_last_block() in order to calculate the starting and
2683 ending blocks in a block group.
2685 Create the generated files read-only to remind developers not to edit them.
2687 Add support for autoconf 2.60 (with backwards compatibility for older
2688 versions of autoconf).
2690 Added an "make rpm" target to top-level Makefile
2692 Added various FreeBSD portability fixes.
2694 Exclude mercurial files from the RPM build tree to speed up copy/build.
2696 Use root_sysconfdir to define the locations of mke2fs.conf and
2697 e2fsck.conf instead of using a hard-coded /etc pathname.
2699 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2701 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2703 If diff -u is supported, use it to report test failures.
2705 Updates/improvements to RPM spec file
2707 Add on-disk format definitions for the following new features:
2708 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2709 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2710 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2712 Add a new make target "checked-failed" in the tests directory which
2713 reruns any failed tests
2715 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2717 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2718 pointer dereferences, memory leaks, etc. None were security-criticial
2721 Fix up usage and decrement error messages in the test_icount program
2723 Add debugging code to the com_err library; if the environment variable
2724 COMERR_DEBUG is set to 1, print out debugging messages as error tables
2725 are added and removed from the com_err library. If the
2726 COMERR_DEBUG_FILE environment variable is set (and the process is not
2727 setuid) the debugging messages may be redirected to a file.
2729 Change all of the e2fsprogs programs to use the newer add_error_table()
2730 and remove_error_table() interfaces instead of the much older
2731 initialize_*_error_table() function.
2733 Add TDB support into the ext2fs library. This allows us to have a
2734 guaranteed library we can count on always being present so we can
2735 store data in an on-disk database.
2737 Add support for using TDB to store the icount data, so we don't run out
2738 of memory when checking really large filesystems.
2740 Change the regression test suite so that it skips empty test directories.
2742 Define the l_i_iversion field in ext2_inode. The l_i_version field is
2743 now defined from the old l_i_reserved1 field in the ext2 inode. This
2744 field will be used to store high 32 bits of the 64-bit inode version
2747 Add Makefile production rule for e2fsprogs.spec in case it gets
2750 Add new function profile_get_uint() to allow for a clean way to fetch
2751 unsigned integers from the context.
2753 Add test to make sure the ext2 superblock structure is 1024 bytes.
2755 Fix typo in name of f_dup4 regression test
2757 Add new function blkid_gc_cache() which performs a garbage collection
2758 pass on the /etc/blkid.tab file.
2760 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2761 general, only e2fsck (after the filesystem is clean), tune2fs, and
2762 resize2fs should change the backup superblocks by default. Most
2763 callers of ext2fs_open() should not be touching any superblock fields
2764 which require the backups to be touched.
2766 Add new function to libext2fs, ext2fs_default_journal_size(), which
2767 returns the default journal size.
2770 E2fsprogs 1.39 (May 29, 2006)
2771 =============================
2773 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2774 between 2**31 and 2**32 blocks.
2776 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2777 configure the filesystem features, blocksize, and inode_ratio for
2778 different filesystem types.
2780 Mke2fs will now create filesystems hash trees and on-line resizing
2781 enabled by default, based on the new /etc/mke2fs.conf file.
2783 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2784 filesystem device node in exclusive mode to prevent accidents by
2785 system administrators. In the case of resize2fs and mke2fs, it will
2786 only use exclusive mode if the filesystem is not mounted.
2788 Fixed a bug in mke2fs which caused it to to fail when creating the
2789 resize inode for large filesystems. (Addresses Debian Bug #346580)
2791 When allocating space for the RAID filesystems with the stride
2792 parameter, mke2fs will now place each portion of the group's inode
2793 table right up after the superblock (if present) in order to minimize
2794 fragmentation of the freespace.
2796 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2797 efficiently by writing the inode and block bitmaps in one pass, thus
2798 reducing the number of disk seeks required.
2800 Add support for on-line resizing to resize2fs.
2802 Fix blkid library so that logic to determine whether or not a device's
2803 cached information in /etc/blkid.tab needs to be verified or not
2804 doesn't get confused by a system clock which is insane (for example,
2805 if the battery is dead on a Macintosh running PPC Linux. (Addresses
2806 Red Hat Bug: #182188)
2808 The blkid library will now store the UUID of the external journal used
2809 by ext3 filesystems, so that in the future, the userspace mount binary
2810 can use this to find the location of the external journal and pass
2811 this information to the kernel.
2813 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2814 control how various options should be handled. See the e2fsck.conf
2815 man page for more details. (Addresses Debian Bug: #150295)
2817 E2fsck now prints an explanatory message when delaying a filesystem
2818 check when the system is running on battery. (Addresses Debian Bug:
2821 E2fsck will detect if the superblock's last mount field or last write
2822 field is in the future, and offer to fix if so. (Addresses Debian Bug
2823 #327580) These problems will be fixed automatically in preen mode
2824 since Debian's boot sequence bogusly doesn't set the time correctly
2825 until potentially very late in the bootup process, and this can cause
2826 false positives which will cause users' systems to fail to boot.
2827 (Addresses Debian Bugs #343662 and #343645)
2829 E2fsck now checks to see if the superblock hint for the location of
2830 the external journal is incorrect, and if so, offer to update it.

2833 Fix e2fsck from segfaulting on disconnected inodes that contain one or
2834 more extended attributes. (Addresses Debian Bug: #316736, #318463)
2836 E2fsck will stop and print a warning if the user tries running a
2837 read/write badblocks test on a read-only mounted root filesystem.
2839 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2840 C. Thompson for pointing these out; they were originally found using
2843 When resizing a file containing a filesystem, resize2fs will expand or
2844 truncate a file as necessary. (Addresses Debian Bug: #271607)
2846 Resize2fs will now automatically determine the RAID stride parameter that
2847 had been used to create the filesystem, and use that for newly created
2848 block groups. The RAID stride parameter may also be manually specified
2849 on the command line using the new -S option to resize2fs.
2851 Fix mke2fs so that it correctly creates external journals on
2852 big-endian machines (such as a S/390).
2854 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2855 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2856 Chambraud for pointing this out.)
2858 Dumpe2fs will now print the size of the journal (if present).
2860 Fix debugfs's set_inode_field command so it can properly set the frag,
2861 fsize, uid_high, gid_high, and author fields in the inode instead of
2862 silently failing, and so that setting the i_size actually sets i_size
2865 Add a new debugfs command, set_current_time, which sets fs->now so
2866 that regression test suites can repeatedly modify the filesystem's
2869 Fix a bug in debugfs's icheck which would incorrectly report the owner
2870 of an extended attribute block.
2872 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2873 print a usage message when an illegal option character is given.
2875 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2876 so it won't core dump. (Addresses SourceForge bug #1424311)
2878 Fix mklost+found so that it creates a full-sized directory on
2879 filesystems with larger block sizes.

2895 that the "best" (i.e., leaf) device is probed by the blkid library.
2897 Fix the blkid library so that it notices when an ext2 filesystem is
2900 Improve the blkid's library VFAT/FAT detection; it now understands
2901 labels stored in the root directory, and is more paranoid about

2905 LVM tools. (Addresses Debian Bug: #345832)
2907 Add support for the reiser4 and software suspend partitions to the
2908 blkid library. Also add support for extract the label from iso9660

2912 continuations are used in the .et file.
2914 Add extra sanity checks to protect users from unusual cirucmstances
2915 where /etc/mtab may not be sane, by checking to see if the device is

2939 Update config.guess and config.sub to latest version (2006-02-23) from
2942 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
2943 Bugs: #360661, #360317)
2945 Fixed the Makefile so that they work correctly on newer versions of
2946 GNU make (i.e., 3.81).
2948 Add valgrind support to the regression test suites, and eliminate
2949 false positives from valgrind.
2951 Add a regression test suite for the blkid library.
2953 Fix a fencepost error in resize2fs caught by valgrind.
2955 Fix compiler warnings about missing memcpy prototypes.
2957 We no longer have the sparc assembly code in the header file any more,
2958 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2959 break compiles on the sparc architectures when using gcc.
2961 In the libext2fs library, add the new field fs->now which if non-zero
2962 is used instead of the system time when setting various filesystem
2963 fields (last modified time, last write time, etc.)
2965 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2966 ext2fs.h which is needed since the inline functions use memcpy().
2967 (Addresses Sourceforge Bug #1251062)
2969 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2970 the build system when building files in the util directory which are
2971 needed during the build process. This avoids potential problems when
2972 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2973 are not recognized as valid by the host compiler. (Addresses
2974 Sourceforge Bug #1261547)
2976 Clean up the blkid library by making the superblock and generic i/o
2977 functions to be more generic. Clean up interface to the probe
2978 function, and fix memory leak. Finallly, remove an unneeded reference
2979 to probe.h in the lib/blkid/resolve.c
2981 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2982 of invalid block #'s.
2984 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2985 indicate that the the function read/writes the memory location.
2987 Fix various gcc -Wall complaints.
2989 Add a dependency to make sure that the subdirectories are created
2990 before creating all of the object files, in order to address parallel
2991 build problem in the library Makefiles. (Addresses Sourceforge Bug:
2994 Add $(LDFLAGS) to the command line argument when generating an ELF or
2995 Solaris shared library, to allow cross-compile and other builds that
2996 might need to specify -L paths to needed libraries. (Addresses
2997 Sourceforge Bug #1261549)
2999 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3000 intended for testing purposes. It allows an ext2/ext3 developer to
3001 create very large filesystems using sparse files where most of the
3002 block groups are not initialized and so do not require much disk
3003 space. Eventually it could be used as a way of speeding up mke2fs and
3004 e2fsck for large filesystem, but that would be best done by adding an
3005 RO_COMPAT extension to the filesystem to allow the inode table to be
3006 lazily initialized on a per-block basis, instead of being entirely
3007 initialized or entirely unused on a per-blockgroup basis.
3009 Fix backwards compatibility so e2fsprogs will better compile on Linux
3012 Make test scripts more robust against locale-related environment variables
3014 Fix type warning problem with sizeof() in ext2fs_open2().
3016 Fix type warning problem with time_t in debugfs.
3019 E2fsprogs 1.38 (June 30, 2005)
3020 ==============================
3022 Fix blkid's test programs (built with "make check") compile correctly
3023 even without "configure --enable-blkid-debug".
3025 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3026 type aliasing rules on newer gcc compilers. (Addresses Red Hat
3029 Fix com_err library to make it more compatible with recent changes
3030 made to the com_err library in MIT Kerberos V5 version 1.4.
3031 (Addresses Sourcefroge Bug #1150146)
3033 General cleanup of messages printed by e2fsprogs programs for grammar,
3034 consistency, and to make life easier for translators. Fixed a few
3035 strings containing English that had not been marked as needing
3036 translations. Removed strings that do not need to be translated, to
3037 make life easier for translators.
3039 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3040 test to see if a device appears to be in use instead of just relying
3041 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
3043 Fix portability problem in the filefrag program affecting platforms
3044 where the size of an integer is smaller than the size of a long.
3045 (Addresses Debian Bug #309655)
3047 Mke2fs will now use a larger journal by default for filesystems
3048 greater than 4GB. (128 MB instead of 32MB).
3050 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3051 unless forced. This is to avoid signed vs. unsigned kernel bugs in
3052 block numbers that still need to be fixed.
3054 The blkid program has a new option which will more efficiently search
3055 for device when it is known (or expected) that only one matching
3056 device will be found in the system, such as when doing a lookup by
3059 Debian's e2fsprogs-specific initrd fragment will avoid including
3060 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3061 and LD_LIBRARY_PATH, and filtering out libraries found in
3062 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
3064 Fixed a potential portability issue in the blkid programs for
3065 architectures where the char type is unsigned. (Addresses Sourceforge
3068 Fix a bug in filefrag so that it doesn't falsely count an extra
3069 discontinuity when the first block found is an indirect block.
3070 (Addresses Debian Bug #307607).
3072 Fix blkid's recognition of cramfs filesystems, and enhance it to be
3073 able to handle cramfs labels.
3075 Fix debugfs's stat command to not core dump when a filesystem is not
3078 Fix e2fsck's handling of error conditions caused by the resize inode
3079 claiming blocks that are also used by other inodes, a filesystem
3080 corruption which was commonly caused by a bug in Fedora Core 3's
3083 Fixed bug in filefrag which caused it to fail on non-ext2/3
3084 filesystems. (Addresses Debian Bug: #303509)
3086 If the superblock last mount time indicates that the system clock may
3087 not be accurate, then e2fsck will omit checking inodes' deletion time
3088 field for indications of a potential corrupted orphaned inode list.
3089 (Previously e2fsck only ommited these LOW_DTIME checks when the
3090 superblock's last write time looked insane.)
3092 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
3093 (Addresses Debian bug #302200)
3095 Make the blkid library more paranoid about being run from setgid
3096 programs, and to use __secure_getenv() from libc if it is available.
3098 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3099 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
3100 and Sourceforge Bug: #1189803)
3102 Updated and fixed translations.
3104 Fixed various Debian packaging issues --- see debian/changelog for
3110 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3111 changed to take an unsigned int for the bit number. Negative bit
3112 numbers were never allowed (and didn't make any sense), so this should
3113 be a safe change. This is needed to allow safe use of block numbers
3114 greater than or equal to 2**31.
3116 The compile_et program will avoid recreating generated foo_err.c and
3117 foo_err.h files if no changes are necessary. The compile_et program
3118 will also atomically replace these files to avoid a potential parallel
3119 build race problem on SMP systems. (Addresses Sourceforge Bug:
3122 Added a new function to the blkid library, blkid_probe_all_new(),
3123 which only probes newly added disk devices, and change
3124 blkid_find_dev_with_tag() to use this function so that when a
3125 requested tag is not found, devices that were previously not checked
3126 are searched before searching all devices in the system.
3128 Added new functions to the blkid library, blkid_dev_set_search() and
3129 blkid_dev_has_tag().
3131 E2fsck's problem strings can now use @m and @n as abbrevations for
3132 "multiply-claimed" and "invalid", respectively.
3134 The e2fsprog.pot file now has an explanation of how the @-expansion
3135 and %-expansion works, and strings in e2fsck/problem.c which contain @
3136 characters now have comments in e2fsprogs.pot with the @-expansion to
3137 make life easier for translators.
3139 Fixed missing return values in the ext2fs library which could cause it
3140 to return random garbage in certain error conditions.
3142 Allow the current time to be overriden via the E2FSCK_TIME environment
3143 variable for use in regression tests.
3145 The test scrpit driver program now exits with a non-zero status if
3146 there any of its test that it ran failed.
3148 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
3151 Fixed "make check" so that it compiles correctly even when e2fsprogs'
3152 header files have not be installed in the system include directories.
3153 (Addresses Sourceforge Bug: #1180572)
3155 Fixed gcc -Wall nits.
3158 E2fsprogs 1.37 (March 21, 2005)
3159 ===============================
3161 Add support for checking the validity of Extended Attributes stored in
3164 Add support for dumping the contents of large inodes to debugfs,
3165 including the extended attributes stored in inodes.
3167 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3168 when we create a new inode we make sure that the extra information in
3169 the inode (any extra fields in a large inode and any ea-in-inode
3170 information) is initialized correctly. This can take place when
3171 mke2fs creates the root and lost+found directory, when e2fsck creates
3172 a new root inode or a new lost+found directory, and when the user uses
3173 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3174 create inode could inherit garbage (or old EA information) from a
3175 previously deleted inode.
3177 Fixed a bug in e2fsck so it would notice if a file with an extended
3178 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3181 Added support to filefrag to detect files which are using the new
3182 experimental file extents format, and use the non-ext2 algorithm in
3183 that case. Fixed a bug to avoid reporting a false discontinuity if
3184 there is one or more unallocated blocks at the beginning of a file.
3186 Duplicated a check for noticing whether or not the number of blocks
3187 (given a certain blocksize) is greater than 2**32 when the
3188 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3189 allows mke2fs to automatically use a larger blocksize when creating a
3190 filesystem on a very large device when run on systems that do not
3191 support BLKGETSIZE64.
3193 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3194 build system had been switched to treat the .gmo files as shipped
3195 files (for backwards compatibility with systems that have older GNU
3196 I18N tools installed), but the gen_tarball.in script was still
3197 removing the .gmo files from the official source distribution.
3199 Fixed various Debian packaging issues --- see debian/changelog for
3200 details. (Addresses Debian Bugs ##296769, #299341)
3205 Added new functions to the e2p library which convert between a string
3206 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3207 make the generated binaries more compact.
3209 Fixed a compile-time error on Darwin systems.
3211 Cleaned up the lib/ext2fs Makefile slightly.
3214 E2fsprogs 1.36 (February 4, 2005)
3215 =================================
3217 All of the patches that were applied to Fedore Core 3's
3218 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3219 lot of bug fixes first. Users of Fedora Core 3 are strongly
3220 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3222 Add support for filesystem with the online resizing via resize inode
3223 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3224 patches also didn't bother to do any consistency checking on the
3225 resize inode, or add any tests to the regression test suite. The "-R
3226 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3227 being listed in mke2fs's usage message. All of these shortcomings
3228 have been corrected.
3230 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3231 program. In order to do this, the user must run the commands:
3233 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3234 e2fsck -f /dev/hdXXX
3236 Optionally, the ext2prepare command can be used to re-enable online
3237 resizing after the filesystem has been fixed.
3239 The fsck program will now accept an optional filedescriptor argument
3240 to the -C option. (The Fedora version of this patch would sometimes
3241 cause fsck to ignore a parameter on fsck's command line in some rare
3244 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3247 Make sure resize2fs releases the blocks belonging to the old inode
3248 table blocks when moving the inode table. (Addresses Debian Bug:
3251 Skip the r_resize_inode test if resize2fs is not compiled (due to
3252 configure --disable-resizer)
3254 E2fsck now checks the summary filesystem accounting information, and
3255 if any of the information is obviously wrong, it will force a full
3256 filesystem check. (Addresses Debian Bug #291571)
3258 Fix e2fsck to not complain when the resize_inode feature is enabled,
3259 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3262 Fix e2fsck to note delete symlinks that contain an extended attribute
3263 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3266 Add new utility program, copy_sparse.c, which is very useful
3267 for dealing with large sparse files (such as e2image files).
3269 Add support for jnl_blocks[] for debugfs's set_super_value.
3271 Fix filefrag so that it works correctly with sparse files.
3273 Filefrag -v will print first and last blocks.
3275 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3278 Add mke2fs support so that it can support filesystems larger than 4TB
3279 automatically, by retrying with a 4k blocksize if the device size is
3280 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3283 Change blkid to test for NTFS first because Windows sometimes doesn't
3284 clear enough of the parition to confuse the probing routines into
3285 thinking the old filesystem type is still valid. (Addresses Debian
3288 Add support for swap partition label and uuid's in the blkid library.
3290 Add support to the blkid library to recognize Oracle ASM volumes.
3292 Make blkid -t display all devices that match the specified criteria,
3293 not just the first one, and work more consistently when the blkid
3294 cache file is not available or set to /dev/null. (Addresses Debian
3295 Bug #290530 and #292425)
3297 Badblocks will now correctly display block numbers greater than
3298 999,999,999 in its progress display.
3300 The tune2fs program will not allow the user from setting a ridiculous
3301 number of reserved blocks which would cause e2fsck to assume the
3302 superblock was corrupt. E2fsck's standards for what is a ridiculous
3303 number of reserved block has also been relaxed to 50% of the blocks in
3306 The blkid library will return vfat in preference to msdos, and ext3 in
3307 preference to ext2 (if the journalling flag is set) so that mount will
3308 do the right thing. (Addresses Debian bug #287455)
3310 Mke2fs will now use the -E option for extended options; the old -R
3311 (raid options) option is still accepted for backwards compatibility.
3312 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3314 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3315 (via "32m" or "4g" on the command line) if the user finds this more
3316 convenient than specifying a block count.
3318 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3319 cache conherency problem.
3321 Debugfs now supports a new command, set_inode_field, which allows a
3322 user to manually set a specific inode field more conveniently, as well
3323 as set entries in the indirect block map.
3325 Debugfs's set_super_value command has been enhanced so that the user
3326 can set most superblock fields, including the date/time fields and
3327 some of the more newsly added superblock fields.
3329 E2fsprogs programs now accept an offset to be passed to the file
3330 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3332 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3333 support on the x86 doesn't exist for now, but it can be useful on
3334 other architectures with page sizes greater than 4k. There are 2.6
3335 kernel patches out there which enable this, but they are of this
3336 writing still experimental.
3338 The e2image command now takes the -s option which will scramble
3339 directory entries for raw image files.
3341 Fix a file descriptor leak in the filefrag program.
3343 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3346 Fix bug in debugfs where kill_file would lead to errors when deleting
3347 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3349 Fix bug in the blkid library when detecting the ocfs1 filesystem
3351 Remove obsolete EVMS 1.x and a.out DLL support.
3353 E2fsck will attempt to recover from a journal containing illegal blocks.
3355 Fixed two potential ordering constraint problems in e2fsck which might
3356 cause the filesystem to be corrupted if e2fsck is interrupted during a
3357 (extremely narrow) race window. Thanks to Junfeng Yang from the
3358 Stanford Metacompilation group for pointing this out.
3360 Fixed bug in e2fsck where it would not accurately detect whether or
3361 not the system is running on adaptor if the ACPI device representing
3362 the AC adapter didn't correspond to the what was used on IBM
3365 Change e2fsck to accept directories greater than 32MB.
3367 Fix e2fsck so that a checkinterval of zero disables a time-based check
3370 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3371 to the PAGER environment variable. (Addresses Debian Bug #239547)
3373 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3376 The debugfs program will set the filetype information when creating a
3379 Add debugfs -d option to use a separate source of data blocks when
3380 reading from an e2image file.
3382 Add e2image -I option which allows the e2image metadata to be
3383 installed into a filesystem.
3385 Fixed bug in the badblocks program which caused "done" to always
3386 appear in english even when a translation was available. (Addresses
3389 The blkid program has a new option -o which controls the output format
3390 of the blkid program; this is makes blkid more convenient to use in
3393 Fix a minor bug in uuid library, which was not using the full 14 bits
3394 of clock sequence when generating UUID's.
3396 Fix a Y8.8888K problem in the uuid library.
3398 Logsave now creates a new session id for itself to avoid getting
3399 killed by init whan transitioning between init levels.
3401 Change the licensing of the UUID library to be the 3-clause BSD-style
3402 license; this allows Apple to use the uuid library in Darwin.
3404 Add ocfs and ocfs2 probe support into the blkid library.
3406 Fix a memory and file descriptor leak in the blkid library.
3408 The blkid library will revalidate the device if the system time is
3409 earlier than last verification time of the device, since that
3410 indicates that the system time is probably nottrustworthy.
3412 The blkid library will override the default location of the blkid.tab
3413 file by the BLKID_FILE environment variable, if it is available.
3415 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3417 Add various portability fixes for lame new versions of glibc, Darwin
3418 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3419 Bugs #239934, #264630, #269044, #255589, #289133)
3421 Add support for Windows 9x/NT under Cygwin.
3423 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3424 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3426 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3428 Update the rpm spec files so that it works better with Fedora core 2
3431 Fixed various Debian packaging issues (see debian/changelog). In
3432 particular, fixed the Debian initrd scripts. (#241183, #248050,
3439 Fixed various gcc -Wall warnings.
3441 The uuid library now has new functions uuid_unparse_upper() and
3442 uuid_unparse_lower() which forces the case of the hex digits to be
3443 upper case, or lower case.
3445 The build process has been speeded up by enhancing the subst program
3446 to update the modtime on the generated files even when the generated
3447 file hasn't changed.
3449 The uuid library now uses C99 stdint.h types instead of custom types.
3451 Updated config.guess and config.sub with newer versions from the FSF.
3453 Removed out of date .cvsignore files from the source distribution.
3455 The ext2fs_unlink() function will return an error if both the name and
3456 inode number are unspecified, to avoid doing something surprising
3457 (such as unconditionally deleting the first directory entry).
3458 Directory entries are now deleted by coalescing them with the previous
3459 directory entry if possible, to avoid directory fragmentation. This
3460 is not an issue with the e2fsprogs suite, but may be a problem for
3461 some of the users of libext2fs, such as e2tools.
3463 Add support for version numbers of the form "1.36-rc1".
3465 Fix build of mke2fs.static.
3467 Add basic ext2fs library support for large (EA in inode) inodes.
3469 The test_io mechanism can now abort after n reads or writes to a
3470 particular block. The block is specified by TEST_IO_BLOCK environment
3471 variable, and the read/write count by the TEST_IO_READ_ABORT and
3472 TEST_IO_WRITE_ABORT environment variables. The block data is now only
3473 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3475 UUID_DEFINE() in the uuid library now creates a static variable, with
3476 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3477 be used in header files.
3479 Add support for the install-strip and install-shlibs-strip targets, as
3480 suggested by the GNU coding guielines. "make install" no longer
3481 strips the binaries which are installed.
3483 Remove support for the --enable-old-bitops configure option which was
3484 only for very old sparc systems.
3486 Remove support for --enable-clear-htree; this was only needed during
3487 the early development of the htree patch.
3489 Use Linux-kernel-style makefile output so it is easier to see compiler
3492 Update gettext files to version 0.14.1.
3494 Update to use autoconf 2.5x.
3496 Improved support for compiling e2fsprogs under dietlibc.
3498 Make e2fsprogs portable to Solaris and FreeBSD systems.
3500 Add blkid_verify(), blkid_get_library_version(), and
3501 blkid_parse_version_string() functions to the blkid library.
3503 Add pkg-config files for e2fsprogs's libraries.
3505 Fix "make uninstall" to so that it removes everything that is installed.
3507 Add a configure --enable-maintainer-mode option which enables the
3508 makefile rules to rebuild the configure script from configure.in, and
3509 to reubuild the .gmo files in po directory.
3511 Drop the sparc assembly bitwise operations; it's less efficient
3512 than the GCC 3.4 compile code and triggers compiler warnings on
3513 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

3517 E2fsprogs 1.35 (February 28, 2004)
3518 ==================================
3520 E2fsck has a new -k option, which in conjunction with the -c options,
3521 preserves the existing badblocks list.
3523 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3525 E2fsprogs will now deal correctly with symlinks that contain
3526 extended attribute information, which can be created using SE Linux.
3527 (Addresses Debian Bug #232328)
3529 Remove a double longjump into an invalid stack frame bug in e2fsck.
3530 (This was during an abort sequence, which normally worked on Linux and
3531 caused a core dump on other operating systems.)
3533 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3534 (the NLS library will replace "" with the .po header information).
3536 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3537 dump due to a division by zero error. (Addresses Debian bug #207082)
3539 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3540 when reconnecting a directory requires creating a lost+found
3541 directory. (Addresses Debian bug #219640).
3543 Fixed a bug where e2fsck would bomb out if a journal needed to be
3544 replayed when using an alternate superblock.
3546 E2fsck will give an extra grace period before actually forcing a check
3547 if the laptop is running on battery. The next time fsck runs while
3548 the system is on the AC mains, or after the grace period is exceeded,
3549 the filesystem will be checked. (Addresses Debian bug #205177)
3551 E2fsck will inform the user when there are 5 or fewer mounts before a
3552 filesystem check will be forced. (Addresses Debian bug #157194)
3554 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3555 We now correctly handle the case where there is an overlap between a
3556 block group descriptor or a superblock and a bad block indirect block.
3557 In the case where the indirect block is corrupted, we now suggest
3560 Fix byte swap bugs in e2fsck that caused the journal backup location
3561 in the superblock and symlinks created by SE Linux to be cleared
3562 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
3564 E2fsck -c now replaces the current list of bad blocks with the ones
3567 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3568 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3570 Fix a potential bug in e2fsck which could cause it to core dump when
3571 trying to print the location of the backup superblock.
3573 Protect against a potential core dump in e2fsck when printing a
3574 message about backup superblocks.
3576 Add support for backing up the journal inode location in the
3577 superblock. E2fsck will automatically save the journal information in
3578 the superblock if it is not there already, and will use it if the
3579 journal inode appears to be corrupted. ext2fs_add_journal_inode()
3580 will also save the backup information, so that new filesystems created
3581 by mke2fs and filesystems that have journals added via tune2fs will
3582 also have journal location written to the superblock as well.
3583 Debugfs's logdump command has been enhanced so that it can use the
3584 journal information in the superblock.
3586 E2fsck will now update all superblocks when moving the journal inode.
3588 Shrink the size of the e2fsck executable by moving some initialized
3589 variables to the BSS segment.
3591 E2fsck will avoid printing the ^A and ^B characters which bracket the
3592 progress bar when stdout and stdin are a tty device instead of a pipe
3593 to another program. (Addresses Debian bug #204137)
3595 Debugfs's mkdir command will automatically expand the directory if
3596 necessary. (Addresses Debian Bug: #217892)
3598 Fixed a bug in debugfs so that copying a file from /dev/null uses the
3599 correct mode bits. (Addresses Debian Bug: #217456)
3601 If the environment variables DEBUFS_PAGER and PAGER are not set,
3602 debugfs now searches for the appropriate pager to use, beginning with
3603 /usr/bin/pager, and then falling back to 'more' and 'less'.
3604 (Addresses Debian bug #221977)
3606 Debugfs will now support 2.6 device numbers where the major or minor
3607 number may be larger than 255. (Addresses Sourceforge bug #865289)
3609 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
3611 Chattr now stops processing options when it sees '--'. (Addresses
3614 Fix regression tests so they work correctly when e2fsprogs is compiled
3615 with configure --disable-htree.
3617 Fix bug in uuid library when there is no network card and the library
3618 is generating a time-based uuid. The random MAC address was not
3619 correctly generated to be a multicast address.
3621 Add compile_et extensions from Heimdall that were missed the first time
3624 Fix bug in badblocks when using O_DIRECT; we need to make sure that
3625 we're reading from an offset which is page aligned. For read-only and
3626 read-write tests, we try to recover after an error so that we can
3627 continue reading on page-aligned boundaries. (Addresses Debian Bug
3630 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
3633 Updated and clarified various man pages. (Addresses Debian Bug
3634 #206845, #222606, #214920, #232406)
3636 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
3638 Fixed various Debian packaging issues (see debian/changelog).
3643 Fixed a build problem so that e2fsprogs would compile with the
3644 --enable-profile option to configure selected. (Addresses Sourceforge
3647 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
3648 Bugzilla Bug #112448)
3650 Centralize code which calculates the location of the superblock
3651 and block group descriptors so that it is in a single library routine.
3653 Added two new functions, ext2fs_file_open2() and
3654 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3656 Fix compile_et to output the correct prototype for
3657 initialize_xxx_err_table_r() in the header file. (Addresses Debian
3660 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3662 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3663 present. This is for when we try stuffing an int into void * pointer.
3665 Fix type-punning which can cause gcc 3.x to miscompile code by getting
3666 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3667 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3668 **'. The EVMS code uses an ugly union approach since we don't want to
3669 modify the EVMS interfaces.
3671 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3672 aid build process on systems can use invoke GNU make as "gmake".
3674 Added regression testing for mke2fs.
3676 Fixed gcc -Wall nitpicks.
3678 Fixed various compiler warnings.
3680 Add portability fixes for FreeBSD and for using fsctl under Darwin to
3681 support ext2 ioctl's.
3684 E2fsprogs 1.34 (July 25, 2003)
3685 ===============================
3687 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3688 a tight loop while waiting for a child fsck to exit in some cases.
3689 This burns CPU times which slows down the low-level filesystem check.
3691 Added code to mke2fs to assure that the default block size for a
3692 filesystem is at least as big as the sector size of the device, if it
3695 Changed mke2fs and resize2fs to round the default size of a filesystem
3696 to be an even multiple of the VM pagesize in order to avoid a Linux
3697 kernel bug introduced when the storage of the buffer cache was moved
3698 into the page cache.
3700 Mke2fs will warn the user when creating a filesystem with journaling
3701 and a blocksize greater than 4096. (Addresses Debian bug #193773)
3703 Fixed a bug in resize2fs which caused it to fail on filesystems with a
3704 non-empty bad block list. Resize2fs now discards any blocks on the
3705 badblock list which are no longer part of the filesystem as the result
3706 of a filesystem shrink. (Note: this means that shrinking and then
3707 enlarging a filesystem is no longer a reversible operation;
3708 information about bad blocks in the part of the filesystem which is to
3709 be chopped off will be lost.)
3711 Changed resize2fs so the user can use prefixes to specify the units of
3712 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3713 and to make the error and informational messages explicitly display
3714 the blocksize used by the filesystem, in order to avoid confusion.
3715 (Addresses Debian bug: #189814)
3717 Added a new debugfs command, dump_unused, which dumps the contents of
3718 all unused blocks to stdout. (Useful as an emergency try-to-find
3719 deleted data command.)
3721 Added a new debugfs command, imap, which prints the location of a
3722 specified inode in the inode table.
3724 Fixed a bug in the badblocks program which caused it to use one bit of
3725 randomness in its non-destructive read/write test, instead of using a
3726 full 8 bits of randomness.
3728 Added a new option (-t) to badblocks, which allows the user to control
3729 the test pattern(s) used when checking a disk.
3731 The blkid probe function now more correctly detects UDF filesystems.
3733 Fixed a bug in the blkid library which caused it to not update its
3734 cache if a filesystem changes from having a label to not having a
3737 Fixed a bug in the blkid library wihch could avoid an infinite loop
3738 in blkid_find_dev_with_tag() if /proc is not mounted and there the
3739 /etc/blkid.tab file has not yet been created.
3741 Fixed the badblocks program so that the destructive read/write test
3742 honors the -c option, and to use O_DIRECT when possible to avoid
3743 thrashing the system block buffer cache.
3745 Fixed various NLS issues.
3746 - Added Czech and Swedish translations
3747 - Removed testing NYC translation
3748 - Fixed NLS support for message abbrevations in e2fsck
3749 - Remove de-utf.po, since we shouldn't have two versions using different
3751 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3752 simplify the statistics reporting in e2fsck.
3754 Changed configure.in so that its defaults for *BSD systems no longer
3755 build an fsck wrapper, and not to install in /usr/local by default.
3757 Fixed some minor spelling errors/typo's in e2fsck and the configure
3760 Fixed various Debian packaging issues (see debian/changelog).
3762 Updated and clarified man pages. (Addresses Debian Bug #195616)
3767 Fix gcc -Wall nitpicks.
3769 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3770 NLS support by default. (Added partial workaround for gettext/Darwin
3771 incompatibility problems.)
3773 Added full MIT KRB5 and Himdall compaibility support to the com_err
3774 library and the compile_et program. (Addresses Debian bug #191900)
3776 Added the blkid_known_fstype() function to the blkid library, which
3777 returns true if it is passed a filesystem type which is recognized by
3778 the blkid probing functions.
3780 Improved the documentation for the blkid library.
3782 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3783 returns the hardware sector size of a device, if it is available.
3785 Added a dependency in the blkid library's .so file to the uuid
3786 library, since the former uses the latter. (Addresses Debian bug
3789 Added --with-diet-libc and --disable-evms to the configure script.
3791 Fixed a minor memory leak in the badblocks program.
3793 Fixed a portability problem in tune2fs --- not all systems have strptime().
3795 Fixed a portability problem in debugfs with the use of getopt() more
3796 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3799 Add support Windows support to ext2fs_get_device_size().
3801 Added (normally disabled) debugging code to the Unix I/O manager which
3802 causes it to disable all userspace caching if the NO_IO_CACHE is
3805 Changed the test I/O manager so it can always be linked into e2fsck,
3806 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3807 configure script. The test I/O manager will only print any debugging
3808 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3809 variables are set, which specifies which I/O operations are logged and
3810 a block number to watch, respectively. The log messages are sent to
3811 stderr by default, unless a filename is specified via the
3812 TEST_IO_LOGFILE environment variable.
3815 E2fsprogs 1.33 (April 21, 2003)
3816 ===============================
3818 Added a new utility program, logsave, which captures the output of a
3819 command in a log file, even if the containing directory hasn't been
3820 mounted yet (in which case the it saves the output in memory until it
3821 can write out the logfile). This is useful for capturing the
3822 output of fsck during the boot sequence.
3824 Fixed some portability problems that were causing problems under
3825 the Cygwin32 environment.
3827 Mke2fs now interprets a negative number to the -b option as a minimum
3830 Fixed a bug in mke2fs which was incorrectly checking the argument to
3831 the -g option if the default block size was used. (Addresses Debian
3834 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3835 it can not find filesystem checkers for jfs, reseirfs, and xfs.
3837 E2fsck now updates the global free block and inode counters from the
3838 block group specific counters quietly. This is needed for an
3839 experimental patch which eliminates locking the entire filesystem when
3840 allocating blocks or inodes; if the filesystem is not unmounted
3841 cleanly, the global counts may not be accurate.
3843 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3844 2.0 is not yet supported; this only pulled in the bug fixes: fixed
3845 possible hangs caused by bugs in calling waitpid, and not setting the
3846 pipe to non-blocking mode; also fixed a file descriptor leak; made
3847 sure all functions call log entry/exit functions.)
3849 Badblocks now flushes its output file as bad blocks are discovered.
3851 The uuid library is now more paranoid about assuming the correctness
3852 of the /dev/random device; it mixes in a stream of bytes from
3853 random/srandom, just in case.
3855 Update Debian files to reflect the fact that I am now the Debian
3856 maintainer of e2fsprogs. Other various Debian-specific packaging
3859 Move the source tarball generation functions from the top-level
3860 makefile to the util/gen-tarball script.
3862 Updated the Turkish .po translation file.
3864 Added Heimdal and MIT krb5 extensions to the com_err library to make
3865 it more compatible with com_err libraries from those distributions.
3867 Changed dumpe2fs to always display the superblock fields relating to
3868 the journalling and/or directory indexing feature even if those
3869 features are not enabled.
3871 Updated and clarify copyright statement vis-a-vis alpha releases of
3874 The ss library will now try to dynamically link to the readline
3875 library and use it if it is present in the system. This means that
3876 the debugfs program now has line editing and history features. The
3877 SS_READLINE_PATH environment variable is used to find a readline or
3878 readline-compatible library.
3880 E2fsck now finds most duplicate filenames (all when rebuilding all
3881 directories via the -D option) and offers to delete or rename
3882 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3884 Fix bug in e2image. When writing out a raw image file, include data
3885 blocks from symlinks that do not store the symlink within the inode.
3887 Fix bug in resize2fs which incorrectly moved the block and inode
3888 bitmaps for sparse superblock filesystems and incorrectly marked
3889 blocks as in use. (Addresses Debian bug #174766)
3891 Added a new shared library, the blkid library, which efficiently
3892 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3893 and UUID filesystem specifiers without needing to search all of the
3894 devices in the system. Instead, the device is looked up in a cache
3895 file, and then verified to make sure the blkid cache is correct.
3897 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3898 the device name, using the blkid library. (Addresses Debian bugs
3901 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3902 used for spaces in device labels.
3904 Removed 32-bit limitations for debugfs's dump command.
3906 If the user specifies a large number of inodes, Mke2fs will
3907 automatically adjust the number of blocks per group to find a valid
3908 set of filesystem parameters.
3910 Add workaround to detect broken MD devices where when some of the
3911 underlying devices are marked read-only, writes to the MD device are
3912 silently dropped. E2fsck will detect if there is an attempt to run
3913 the journal twice, and abort with an error if this is the case.
3914 (Addresses IBM Bugzilla bug #1226)
3916 E2fsck will print an error if more than one of the -p/-a, -n or -y
3917 options are specified.
3919 E2fsck will fix HTREE corruptions in preen mode, without stopping the
3920 boot process. This is needed because the 2.4 ext2 filesystem
3921 accidentally had the INDEX_FL backwards compatibility code removed.
3923 Mke2fs no longer creates filesystems with the dir_index flag set by
3924 default; the user has to specifically request it.
3926 Update and clarified various man pages. (Addresses Debian bugs
3927 #173612, #175233, #175113, and #170497, #185945, #188318)
3929 Created man page for the mk_cmds program (from the libss library).
3934 Fix various gcc -Wall nits.
3936 Fixed a lot of portability problems that caused e2fsprogs not to build
3937 successfully under Solaris and Apple/Darwin.
3939 Fixed a Makefile dependency to allow building e2fsprogs using parallel
3942 Changes to create a subset distribution which consists only of the
3943 et, ss, uuid, and blkid libraries. The configure script and top-level
3944 makefile were changed to support working with a subset distribution.
3946 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3947 actually used, and might people who are looking for
3948 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3950 Updated debian files to fix a number of Lintian warnings.
3952 Updated config.guess and config.sub with newer versions from the FSF.
3954 Removed unnecessary libraries from being linked into the fsck, lsattr,
3955 chattr, and blkid executables.
3957 E2fsprogs 1.32 (Nomvember 9, 2002)
3958 ==================================
3960 Fixed a bug in the Unix I/O routines which caused needless writebacks
3961 of clean blocks from the unix_io cache (they were erroneously marked
3962 as being dirty, so they were getting written back to disk before
3963 getting evicted from the disk cache). This was harmless, but it
3964 significantly slowed down e2fsck.
3966 Made some other minor optimizations to the Unix I/O routines to save a
3967 small amount of CPU time.
3969 Updated internationalization files.
3972 E2fsprogs 1.31 (Nomvember 8, 2002)
3973 ==================================
3975 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3976 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3977 handling for child process that die unexpectly. Add a hack to force
3978 mkfs to create filesystems that won't cause problems with hardware
3979 that has 2k or 4k minimum blocksize requirements. Read from child
3980 processes in non-blocking mode, so that the GUI continues to update.
3982 Fix e2fsck so that it returns the appropriate exit code when the root
3983 filesystem has been changed, so that system's rc scripts will be told that
3984 the system needs to be rebooted.
3986 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3987 was set, some of the descriptor blocks that should have been written
3988 out were getting skipped.
3990 Changed e2fsck to force out changes to the backup copies of the
3991 superblock and block group descriptors when important changes are made
3992 to those data structures.
3994 Fix a bug where e2fsck could erroneously mark a filesystem as being
3995 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3996 introduced in e2fsprogs 1.28.)
3998 If journal debuging is enabled using --enable-jbd-debug, the debugging
3999 level is now set via the E2FSCK_JBD_DEBUG environment variable.
4001 If byteswapping support is disabled using configure --disable-swapfs,
4002 skip the tests which depend on byte-swapping, so that "make check"
4005 Lshattr will now display the indexed directory flag. Also, some of
4006 the more esoteric compression flags are supressed unless compression
4007 support has been enabled.
4012 E2fsprogs 1.30 (October 31, 2002)
4013 =================================
4015 When resizing a filesystem, and inodes need to moved, resize2fs will
4016 update the inode's ctime field, and the mtime field of the containing
4017 directories, so that incremental backups using dump/restore will work
4020 In order to avoid spurious errors, e2fsck wil check the last
4021 superblock write time to determine whether or not it can safely use
4022 the LOW_DTIME checks to determine if there are inodes on the orphan
4023 inode linked list that had somehow gotten disconnected. (Addresses
4024 Sourceforge bug #620980)
4026 Partition in /proc/partitions that being with the string "lvm" are
4027 considered real partitions even if they do not end with a number.
4029 Fixed a bug in the the uuid generation function, where if /dev/urandom
4030 is not present, but /dev/random is, and there isn't sufficient
4031 entropy, the get_random_byte function could spin a loop forever.
4033 E2fsck, mke2fs, etc. will now reliably notice when image files are
4034 mounted using the loopback interface. (Addresses Sourceforge bug
4037 When flushing buffers (as is done by badblocks, for example) check to
4038 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4039 FDFLUSH ioctl which causes the MD device driver which causes confusing
4040 syslog messages about obselete ioctl messages. (Addresses Sourceforge
4043 Debugfs's write command now checks to see if the destination filename
4044 exists before creating it. (Addresses Sourceforge bug #478195.)
4046 When installing man pages, search for compressed man pages using all
4047 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4049 Fixed a bug in fsck where multiple filesystems specified on the
4050 command were not being checked in parallel due to a logic bug
4051 introduced to support the FSCK_MAX_INST environment variable.
4053 We have added a new superblock field, s_mkfs_time, which indicates
4054 when a filesystem was created. It is set via mke2fs, and printed out
4055 by dumpe2fs, but is not actually touched by the kernel.
4057 Dumpe2fs has been made more robust by not aborting if there is an
4058 error reading the block/inode bitmaps; instead it will still print out
4059 the location of the block/inode bitmaps and inode table.
4061 Add support for the an alternative block group descriptor layout which
4062 allows for on-line resizing without needing to prepare the filesystem
4063 in advance. (This is the incomat feature flag meta_bg.)
4065 Add support for storing default mount options in the superblock, so
4066 that the filesystem can be mounted with specific mount options without
4067 needing to specify them on the mount command line or in the /etc/fstab
4070 Add support for a new inode flag, which is to be used for indicating
4071 the top of directory hierarchies for the Orlov block allocator.
4073 Fix e2fsck so that if it creates the lost+found directory, it does so
4074 with the more apporpriate permissions of 0700. Also change
4075 mklost+found so that it also creates the directory 0700.
4077 Fixed format bug in e2fsck if NLS is in use.
4079 Add a German translation for e2fsprogs's NLS support.
4081 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4082 the beginning of the inode table. This won't matter much, since if
4083 there is a bad block at the beginning of the inode table, the root
4084 directory won't be available. But at least e2fsck won't crash in this
4087 Fixed endian problems in the htree code for e2fsck and debugfs.
4089 When byte-swapping a filesystem on a PPC architecture, byte-swap the
4090 bitmaps since the historical big-endian ext2 variant had byte-swapped
4091 bitmaps, and the ext2fs library assumes this. This fixes the
4092 regression test suite on PPC machines.
4094 Fix e2image so that it handles a bad block in the inode table
4097 E2fsck now uses a more sophisticated algorithm to salvage corrupted
4098 directories that recovers more information in the corrupted directory
4101 E2fsck now performs additional consistency checks on indexed (HTREE)
4104 Fix bug where efsck might get confused about whether a completely
4105 empty directory block is an empty leaf block or an interior htree
4106 node. This could cause e2fsck to get confused into think that a valid
4107 indexed directory was corrupted.
4109 E2fsck no longer creates an empty directory entry at the end of a
4110 directory block when optimizing a directory. This would cause some
4111 earlier versions of the dxdir kernel code to corrupt the directory
4112 when attempting to split a node containing an empty directory entry.
4114 E2fsck could sometimes in rare circumstances leave the indexed flag
4115 set after a small directory was optimized by compressing it instead of
4116 indexing it. (This should never happen in real life, since
4117 directories that small wouldn't have been indexed, but better safe
4120 E2fsck now only updates the master superblock in all cases. This
4121 slightly shortens its run time.
4123 Ext2ed can deal with directory entries of length 0; previously it
4124 would get stuck in an infinite loop.
4126 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4127 specifiers. (Sourceforge patch #613447)
4129 Badblocks will now work correctly on read-only devices such as
4130 CD-ROM's. (Sourceforge patch #600451)
4132 Updated and clarified man pages. (Addresses Debian bug #167108)
4135 E2fsprogs 1.29 (September 24, 2002)
4136 ===================================
4138 Fixed a bug in e2fsck which could corrupt a directory when optimizing
4139 it (via the -D option) or rebuiliding the hash tree index with a 1 in
4140 512 probability, due to a fence post error.
4142 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4145 Mke2fs now enables the directory indexing flag by default. (Since
4146 this is a compatible feature flag, it's safe to do so.)
4148 Tune2fs will support setting the directory indexing feature flag. It
4149 will automatically set up the default hash algorithm and hash seed
4150 fields in the superblock.
4152 If the bone-headed user enters the root filesystem twice in
4153 /etc/fstab, the -R option which skips the root filesystem will skip
4154 all of them. (Addresses Debian bug #159423). Note! This is not a
4155 precedent for dealing intelligently with any other kind of doubled
4156 entry in /etc/fstab!
4162 Removed perror declaration in lib/et/internal.h. All modern systems
4163 can be expected to define perror() these days. Besides, the lib/et
4164 code wasn't using perror at all anyway. :-)
4167 E2fsprogs 1.28 (August 31, 2002)
4168 ================================
4170 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4171 for setting the htree flag is not included yet, although it can be
4172 manually turned on via the debugfs program.
4174 Clarified e2fsck error message which is printed when it cannot find
4175 sufficient contiguous block when relcating filesystem metadata.
4177 Added support for building an EVMS plugin module for ext2/3. This
4178 module is substantially the same as the EVMS module shipping with EVMS
4179 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4180 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4181 if the configure --enable-old-evms flag is given.
4183 Fsck will search through EVMS volumes when trying to resolve
4184 filesystem specifications such as LABEL=xxx or UUID=xxx.
4186 Added a new utility program, /sbin/findfs, which will return
4187 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4190 Update and clarified various man pages. (addresses Debian Bug #145044,
4191 #146437, #131350, #151990, #144621, #141938)
4193 If there are no filesystems specified on fsck's command line, fsck now
4194 treat that as if the -As options were given. Previously it would
4195 simply do nothing. (Addresses Debian Bug #153102)
4197 Mke2fs no longer treats a failure to be able to clear the MD signature
4198 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4201 The e2p library functions (which are used by lsattr and chattr) now
4202 double check to make sure the file is a regular file or directory
4203 before attempting to use the ext2 ioctls. Some device drivers
4204 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4205 (Addresses Debian Bug #152029).
4207 The extended attribute handling has been updated to correspond with
4208 the latest V2 bestbits ACL code.
4210 Fixed bug in e2fsck which caused it to not clear the dtime field when
4211 processing truncated inodes on the orphan list. This could cause data
4212 loss(!) if a filesystem is rebooted before a truncate has been
4215 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4216 algorithms. This makes e2fsck much faster in the case of severely
4217 corrupted filesystems where a large number of blocks are claimed by a
4218 large number of inodes. (Thanks to the 2.5 IDE device driver for
4219 inspiring this work.)
4221 Resize2fs has been significantly sped up when shrinking and expanding
4222 a filesystem by a very small number of blocks (for example, when EVMS
4223 is converting a partition to be an EVMS legacy volume).
4225 Added a new option to e2fsck, -D, which will optimize or compress all
4226 of the directories in the filesystem.
4228 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4229 properly clean up and only exit at safe points. Fsck will pass
4230 SIGINT/SIGTERM to its child processes, and wait until they have all
4231 exited before it exits.
4233 The uuid parsing code in the uuid library now properly complains when
4234 an illegally formated uuid is presented to it. (Addresses Debian bug
4237 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4238 and 2.4.17, since the workaround can cause problems when using a 2.4
4239 kernel with an old version of glibc built with the 2.2 headers.
4241 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4242 superblock used by other filesystems. (Addresses Debian bug #147256.)
4244 Added support for the synchronous directory feature written by Andrew
4247 The debugfs program can delete directories using the rmdir command.
4249 Add support for 8k and 16k filesystems (for systems with page sizes
4250 that are greater or equal to 8k or 16k, respectively). Note that
4251 these filesystems can not be mounted on x86 systems, or other systems
4252 with only 4k page sizes, due to limitations in the current Linux VM
4255 Resize2fs requires that the filesystem state be valid and have no
4256 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4257 required that the last fsck time be greater than the last mount time.)
4259 Configure now defaults the man pages directory to /usr/share/man on
4262 E2fsck now offers to truncate inodes which contain too many blocks (so
4263 that i_blocks would overflow. Also fixed handling of large sparse
4266 E2fsck now more completely checks for symlink validity, including
4267 requiring NULL termination and length checks.
4269 E2fsck will offer to try forcing a disk write to remap a bad block
4270 after finding a read error when reading a filesystem metadata block.
4272 Fixed a bug in debugfs which caused the -b and -s options to crash
4273 debugfs, as well as breaking the testb, setb, and clearb functions.
4275 Added a bmap command to debugfs which calculates the logical to
4276 physical block mapping for a particular inode.
4278 Fixed a bug in code which checked to see if a device was mounted which
4279 sometimes (rarely) failed in the case of a plain file.
4281 Fixed a bug in resize2fs where when it reported an error, it would
4282 print a message erroneously indicating that the filesystem had been
4283 resized before it aborted.
4285 When resizing a plain file which is smaller than the requested size,
4286 resize2fs will attempt to extended the file so that programs like
4287 e2fsck will not complain that the file is too small.
4289 Resize2fs will print the actual new size of the filesystem when it is
4292 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4293 information on big-endian systems.
4299 Fixed collisions with C++ reserved words.
4301 Added portability fixes for building e2fsprogs on the HURD and AIX.
4303 Added the ext2ed program for creation of test cases. (ext2ed has many
4304 limitations and bugs which make it unsuitable for production use.)
4306 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4307 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4308 name_len field is byte swampped on big-endian machines, since in the
4309 V2 structure, name_len is a char field which is doesn't need to be
4310 byte swapped --- except if an old-style kernel had byte-swapped the
4311 name_len field as part of the V1 structure.
4314 E2fsprogs 1.27 (March 8, 2002)
4315 ==============================
4317 The warning messages for mke2fs now go to standard error.
4319 Fixed to make sure "make check" runs all of the test programs with
4320 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4322 The mke2fs program checks the boot sector for the BSD disk label, and
4323 avoids erasing it if it is there.
4325 Fixed a bug in e2fsck which caused it to core dump if the journal
4326 inode was missing when it was supposed to be there.
4328 E2fsck now prints ranges in pass 5 when printing deltas for the block
4331 Debugfs's "ls -l" command now will print out the file type information
4332 in the directory entry.
4334 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4335 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4337 Debugfs can now examine the experimental directory indexing
4340 Fixed bug in debugfs which caused it to core dump if modify_inode is
4341 called without an open filesystem.
4343 The debugfs lsdel command now runs its output through a pager first.
4345 When installing manual pages, remove the compressed manual pages first.
4347 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4349 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4350 actually broke things on mips32, sparc32, and Alpha platforms.
4352 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4353 (which is required by the newer libintl libraries).
4358 Fixed various gcc -Wall complaints.
4360 Fixed a few memory leaks in the e2fsck journaling code, and in the
4361 ismounted code checking for a swap device.
4363 Add new inode I/O abstraction interface which exports an inode as
4366 Exported ext2_file_flush as a public interface.
4368 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4370 Lots of small random portability fixes to make e2fsprogs build under
4371 AIX --- even without the 5L compatibility toolkit, and even using the
4372 uber-crippled AIX native C compiler.
4375 E2fsprogs 1.26 (February 3, 2002)
4376 =================================
4378 Dumpe2fs will keep going now if the bad block inode can't be read.
4379 (Previously it stopped with a fatal error.)
4381 E2fsck will now give an opportunity to run the journal even if the
4382 recovery flag is not set. This is the default behaviour if e2fsck is
4383 using a backup superblock, since the needs_recovery flag will never be
4384 set in the backup superblock copies.
4386 E2fsck now automatically finds the backup superblock/group descriptors
4387 even when the primary superblock is completely destroyed for 2k and 4k
4388 filesystems. (Previously it just guessed/assumed that we were dealing
4389 with a 1k filesystem in that case, and users had to manually specify
4390 the backup superblock number.)
4392 Fixed a bug in e2fsck where it dereferences a null pointer when there
4393 is a problem opening a filesystem in preen mode.
4395 E2fsck now handles external journals correctly; previously it trashed
4396 the external journal device if the journal needed to be replayed.
4398 Work around ulimit incompatibility problem caused by recent 2.4
4399 kernels; the unix IO module will automatically try to set any resource
4400 limits to be infinite on startup.
4402 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4403 bitmap if it wasn't present and the blocksize was 2k or 4k.
4404 (Addresses Debian Bug #116975)
4406 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4407 clearing the new V2 fields if they do not make sense or if the ext3
4408 superblock is version 1 superblock.
4410 E2fsck will automatically relocate the ext3 journal from a visible
4411 file (i.e., /.journal) to an hidden inode if the filesystem has been
4412 opened read/write. This allows the users to add a journal while the
4413 filesystem is mounted, but the next time the system is rebooted, the
4414 journal file will disappear. This avoids problems with backups,
4415 stupid operators with superuser bits, etc.
4417 Fix a bug in fsck where it would not support a filesystem type of
4418 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4420 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4421 automatically identify reiserfs filesystems.
4423 The number of processes spawned by fsck can now be limited using the
4424 FSCK_MAX_INST environment variable.
4426 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4427 should be searched for UUID and label information.
4429 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4430 limit if at all possible, when opening a block device. (The filesize
4431 limit shouldn't be applied against writes to a block device.)
4433 In mke2fs and e2fsck, specifying the -c option twice will now do
4434 a read/write test on the disk. Update the man pages to encourage
4435 using the -c option, and to discouraging running badblocks separately,
4436 since users tend to forget to set the blocksize when running
4439 Mke2fs now automatically clears the immutable attribute on a
4440 pre-existing .journal file left over from a previous failed attempt to
4441 add a journal to an alreadyy-mounted filesystem.
4443 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4446 Mke2fs now creates the lost+found directory with permissions of 0700,
4447 so that files that had previously lived in protected directory are
4448 safe if they get dropped in lost+found and the system administrator
4449 doesn't deal with immediately. (Addresses Debian #bug 118443)
4451 Mke2fs and e2fsck (and all programs that use the
4452 ext2fs_check_if_mounted function) will now properly identify that a
4453 device is mounted, even in cases where devfs has confused things with
4454 multiple devices names with the same identity, or if a dim-witted
4455 system administrator has done something stupid like creating device
4456 file aliases in their home directory. Also now checks for swap devices
4457 by using /proc/swaps. (Addresses Debian bug #106622)
4459 Added a new option (-T) to tune2fs which sets the time a filesystem
4462 Speed up e2image when creating sparse raw image files by optimizing
4463 away excess lseek() system calls.
4465 Fix support of large (> 2GB) files when used as a filesystem in
4466 mke2fs, tune2fs, debugfs, and findsuper.
4468 Debugfs's stat and icheck commands now properly deals with large (>
4471 Debugfs's set_super_value command now prints out the list of valid
4472 superblock fields which can be set using the command.
4474 Debugfs's rm and kill_file command now updates the superblock free block
4475 and inode counts, thus keeping the filesystem consistent.
4477 Debugfs's lsdel command now takes an optional argument which allows
4478 the user to only see the most recently deleted files.
4480 A new command (undel) was added to debugfs which automates
4481 undeleting a deleted inode and linking it back to a directory.
4483 Debugfs's ls command now takes a new option, -d, which lists
4484 deleted directory entries.
4486 Debugfs's testb, freeb, setb, and find_free_block commands now take an
4487 optional count argument.
4489 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4490 be used to signal that a particular inode should not be eligible for
4491 tail-merging --- this is needed for programs like LILO.
4493 The findsuper (an unreleased, uninstalled utility program) has been
4494 improved to add extra validity checks and to add a progress meter.
4495 (It is still an unsupported program; the officially supported way to
4496 recover from a trashed partition table is to use gpart; findsuper is
4497 for wizards only. :-)
4499 Debugfs was fixed to compile with "configure --disable-swapfs".
4501 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
4503 Added new translation file for Turkish.
4508 Fix general gcc -Wall complaints.
4510 E2fsprogs (mostly) works with the dietlibc.
4512 The programming texinfo file has been expanded to include description
4513 of additional libext2fs functions. (Still not compeltely done, but a
4514 lot of the more important functions have been documented.)
4516 Added a umask structure to struct_ext2_filsys, which currently only
4517 modifies the behaviour of ext2fs_mkdir(), but if we add any file
4518 creation functions to libext2fs, we should also make sure they respect
4521 The build-rpm script was fixed to be a bit more safe.
4523 The tests' Makefile now has a way of automating test case creation
4524 for e2fsck, using "make testnew".
4526 Created a new function, ext2fs_dir_iterate2 which passes more
4527 information to the callback function (identical to the one used by
4528 ext2fs_dblist_dir_iterate). The directory iterator functions take a
4529 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4530 directory entries. If the directory entry is deleted, the callback
4531 function will be called with the entry paraemter set to
4532 DIRENT_DELETED_FILE.
4534 Added new functions, ext2fs_inode_alloc_stats and
4535 ext2fs_block_alloc_stats, which takes updates block/inode allocation
4536 statistics in the bitmaps, block group descriptors, and superblock
4537 when inodes or blocks are allocated or deallocated.
4540 E2fsprogs 1.25 (September 20, 2001)
4541 ===================================
4543 This is primarily a bug-fix release; no new features were added, but
4544 there are a number of embarassing bug fixes and cleanups applied.
4546 Fix a bug mke2fs which causes stack garbage to be written to disk when
4547 zapping disk sectors. (This bug could cause mke2fs to core dump for
4548 some kernels, I suspect with security enhancement patches.)
4550 Remove unneeded #include of <linux/config.h> which was breaking
4551 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
4553 Updated tune2fs man page to reflect the fact that adding or removing a
4554 journal doesn't require running e2fsck.
4556 Remove use of AC_REQUIRE from autoconf which had been used to prevent
4557 AC_CANONICAL_HOST from being called twice; unfortunately this causes
4558 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4559 used outside of autoconf macros. Fortunately, it doesn't seem to be
4560 necessary any more, anyway.
4562 E2fsck will now not fall back to an alternate superblock if the user
4563 specifies the superblock location explicitly on the command-line.
4564 This allows easier recovery from a situation where the primary
4565 superblock and block groups are slightly corrupted, but the backup
4566 superblocks are completely broken.
4568 Fix problem which caused compile_et and mk_cmds to blow up if
4569 e2fsprogs was in a directory with a pathname that contained spaces.
4571 We are now more paranoid about checking the entry in /etc/mtab to make
4572 sure the filesystem is really mounted, since some broken distributions
4573 (read: Slackware) don't initialize /etc/mtab before checking non-root
4574 filesystems. (Slackware also doesn't check the root filesystem
4575 separately, and reboot if the root filesystem had changes applied to
4576 it, which is dangerous and broken, but there's nothing I can do about
4579 Make UUID library C++ friendly by adding appropriate extern "C"
4580 declarations and using const in the function declarations.
4582 Fix up the com_err texinfo file so that it can product a valid info
4583 file (previously, it could only be used to generate paper
4584 documentation using texinfo.tex).
4587 E2fsprogs 1.24a (September 2, 2001)
4588 ===================================
4590 Fix brown-paper bug in mke2fs which caused it to segfault when
4591 printing the version string.
4594 E2fsprogs 1.24 (August 30, 2001)
4595 ================================
4597 Revert the BLKGETSIZE64 support, since for some distributions, this
4598 ioctl has been used by an unofficial kernel patch to update the last
4599 sector on the disk, and this was causing disk corruption problems as a
4602 Mke2fs is now more careful about zapping swap space signatures and
4603 other filesystem/raid superblock magic values so that programs like
4604 mount who try to use hueristics to determine the filesystem type of a
4605 partition are less likely to be confused.
4607 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4608 regular file (since Andreas Dilger's on-line resizing tools will set
4611 Fixed some minor texinfo, man pages nits for spelling errors,
4612 texinfo warnings, etc. (Addresses Debian bug #110621.)
4614 E2fsprogs program no longer print the filesystem version number
4615 (i.e. 0.5b), since it only confuses people and doesn't serve any real
4618 E2fsck will once again compile under libc5, since it will supply its
4619 own version of strnlen if necesssary.
4621 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4622 when specifying the external journal device. tune2fs will also search
4623 devices looking for the externla journal debice when removing.
4625 E2fsprogs 1.23 (August 15, 2001)
4626 ================================
4628 Add initial support for extended attributes (EA); e2fsck will
4629 correctly handle a filesystem with EA's and check the EA blocks for
4632 E2fsck's symlink sanity checking has been cleaned up. It now checks
4633 the i_size value of fast symlinks, and checks for immutable flags
4634 being set of symlinks, etc.
4636 E2fsck now offers to clear inodes which are special files that have a
4637 non-zero i_blocks or i_size field. (The i_size field check was in the
4638 previous version of the code, but due to a bug it didn't offer to
4639 clear the inode unless i_size and i_size_high were both non-zero.)
4641 E2image can now create "raw" image files, which only contain the
4642 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4643 debugfs, etc., can be run directly on the raw image file.
4645 Add support for the 64-bit block device patches.
4647 Fixed bugs in creating external journals with a 1k blocksize.
4649 Add initial support for external journals (so long as the external
4650 journal only supports a single filesystem) in e2fsck.
4652 Remove requirement for needing to run fsck on a filesystem after
4653 removing a journal (either internal or external).
4655 The man pages now document how to create and manage external journals.
4657 Speed up the check of an ext3 filesystems by avoiding a needless flush
4658 of all of the superblock and block group descriptors.
4660 Speed up creating an internal journal using tune2fs in the case where
4661 the filesystem has a lot blocks already allocated.
4663 Tune2fs has been fixed to make sure that only error messages go to
4664 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4666 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4667 now not set the sparse_super feature. (Addresses Debian bug #108165)
4669 Add support in fsck for the filesystem type "auto".
4671 Fsck -A will not try to interpret device names for filesystems which
4672 have a pass number is 0. (Addresses Debian bug #106696).
4674 Fsck prints a warning message if now valid filesystems are passed to
4675 it. (Addresses Debian Bug #107458.)
4677 E2fsck now gives an explicit warning if there filesystem still has
4678 errors at the end of the run. (Addresses Debian bug #104502)
4680 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4681 reflects an error. E2fsck will also not run the orphan list if the
4682 filesystem contains errors, since the orphan list might be corrupted.
4684 E2fsck now prints the number of large files when given the -v option.
4686 Fixed minor memory leaks in e2fsck.
4688 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4691 E2fsprogs 1.22 (June 22, 2001)
4692 ==============================
4694 Fixed a bug in e2fsck's handling of orphan inodes which are special
4695 files (i.e., block/character device files, named FIFO's, etc.).
4697 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4698 tune2fs to fail at adding a journal to a mounted filesystem.
4700 Fixed a few big-endian bugs in e2fsprogs
4701 * The directory block functions were accidentally reporting
4702 some directories as corrupted when they weren't.
4703 * If e2fsprogs is compiled --disable-swapfs, the C language
4704 equivalents weren't being included for big-endian platforms.
4705 (Fixes Debian bug #101686).
4707 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4712 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4713 ioctls, and allow them to be defined for non-i386 platforms.
4715 The uuid.h header file is now protected against multiple inclusions.
4717 E2fsprogs is now being developed using BitKeeper. Changed the test
4718 scripts to deal with BK's stripping CR characgters from text files,
4719 and changed the top-level Makefile.in to avoid including BitKeeper
4720 files when generating the source tarball.
4723 E2fsprogs 1.21 (June 15, 2001)
4724 ==============================
4726 Added new configure flags which allow a subset e2fsprogs to be built;
4727 this is most useful for boot floopies, since the resulting shared
4728 libraries and programs are slimmed down by removing features that
4729 aren't necessary for a boot floppy. The new flags that were added
4730 are: --disable-swapfs, which removes support for byte swapping old
4731 legacy PPC/68k filesystems, --disable-debugfs, which removes support
4732 for debugfs from the libext2fs library, --disable-imager, which
4733 removes support for the e2image program, and --disable-resizer, which
4734 removes support for resize2fs.
4736 E2fsck now prints the number of mounts or days elapsed since the last
4737 check when e2fsck is forced to check an otherwise clean filesystem.
4739 Tune2fs now prints an informative message about how often a filesystem
4740 will be checked when adding a journal to the filesystem, to remind the
4741 user that he/she may want to adjust those parameters using tune2fs
4744 Worked around hurd brain-damage which causes e2fsck to sometimes
4745 believe a filesystem is the root filesystem based on device numbers
4746 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4749 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4750 erroneous error with the -F option was specified.
4752 Fixed a ext3 recovery bug in the revoke handling; synchronized with
4755 Fixed two bugs in e2fsck's handling of dup block handling, dealing
4756 with relatively uncommon edge cases: a directory with an indirect
4757 block which is claimed by another file, and when the last inode in the
4758 filesystem has blocks claimed by another file.
4760 E2fsck now checks to see if the i_size field of a fast symlink is too
4761 big, and offers to clear the symlink if so.
4763 E2fsck now checks to see if i_size_high of special files is non-zero,
4764 and offers to clear i_size_high.
4766 Fix e2fsck's handling of incompatible journal flags so that the user
4767 has chance to abort, and then has the option to clear out the journal
4768 entirely. (Addresses Debian bug #98527.)
4770 Fixed a bug in fsck which could cause it to core dump if a mix of
4771 standard and non-standard device names are used in /etc/fstab.
4772 (Debian bug #100559)
4774 Fixed a bug in debugfs which caused read errors when copying a file to
4777 The debugfs set_super_value command can now modify the s_lastcheck field.
4779 Fixed a bug in lsattr and chattr which was accidentally introduced in
4780 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
4781 directories correctly because the change modified the layout of struct
4782 dirent to be incompatible with the libe2p shared library.
4784 Cleaned up the mke2fs manual page and included a discussion about why
4785 it's good to periodically check the filesystem even when journaling is
4791 Fix general gcc -Wall complaints.
4793 The types needed by the ext2 header files are now provided by
4794 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4796 Integers are now preferred to longs when trying to find a 32-bit type
4797 in ext2_types.h. Also, if linux/types.h has already been defined,
4798 don't try to redefine the types.
4800 Fixed make depend script so that it automatically corrects the
4801 pathname cleanups performed by make -M, so I don't have to fix them up
4804 Fixed the d_loaddump test case to be more robust, and not depend on
4807 Removed debugfs's dependence on pread(), which was accidentally
4808 intrudced in e2fsprogs 1.20
4810 Fixed a performance bug in the libext2fs's icount routine; the size
4811 estimate of the icount array was incorrectly being calculated.
4813 Removed use of the badblocks compatibility functions in the e2fsprogs
4816 Added paranoia code which protects against strange cases where /etc
4817 isn't on the root filesystem, or if /etc/mtab doesn't exist.
4819 The header file ext2_types.h is now installed.
4821 Autoconf is used to determine when we are on big-endian machines,
4822 instead of doing run-time tests, to save a few bytes of code.
4824 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4825 functions are no longer inline functions, which saves space and
4826 doesn't really cost any real performance.
4828 The ext2fs library no longer depends on the e2p library. (What need
4829 there was of it --- namely, fsetflags, was coded in-line).
4831 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4832 when the user is stupid and tries compiling the package using "make
4835 Miscellaneous code cleanups:
4836 * Added missing files from Makefile.in's SRCS file, so that
4837 their dependencies would be properly calculated.
4838 * Removed redundant code
4839 * Fixed comments in code
4840 * Removed no-longer unneeded argsused #pragma.
4843 E2fsprogs 1.20 (May 20, 2001)
4844 =============================
4846 Add support for replaying the ext3 journal purely in user mode,
4847 including handling the orphaned inode list. Used code contributed by
4848 Andreas Dilger, with bug fixes and the orphaned inode handling done
4851 The mke2fs and tune2fs programs can create or modify a filesystem to
4852 include an ext3 journal. Tune2fs also can be used to remove an ext3
4853 journal from a filesystem.
4855 E2fsck will now check for the existence of a linked list of orphan
4856 inodes in the superblock, and clear those inodes before starting the
4857 rest of the filesystem check (but after the journal playback).
4859 E2fsck now validates the file descriptor passed to the -C option,
4860 which saves against the completion bar getting written to an
4861 unexpected location, such as the disk being checked. (Debian
4862 bug/wishlist #55220)
4864 E2fsck will now bump the filesystem revision number from zero to one
4865 if any of the compatibility bits are set.
4867 Fixed a bug where a badly corrupted directory on a big endian system
4868 could cause e2fsck to die with a bus error. The
4869 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4870 the ext2 library now does alignment sanity checks on the rec_len field
4871 of the directory entry before using it.
4873 The ext2 library has been enhanced to make tune2fs safe to run on
4874 mounted filesystems. (Users could usually get away with using tune2fs
4875 on mounted filesystems before, but with the advent of ext3 and
4876 journaling, it became important to make tune2fs was *really* safe for
4877 use even when the filesystem being modified is mounted.) E2label is
4878 now implemented by tune2fs using an argv[0] dispatch, so that e2label
4879 is also now safe for use on mounted filesystems.
4881 Added a new program, e2image, which creates a backup of critical ext2
4882 filesystem data structures. The generated image file can be examined
4883 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4884 the image file to help recover very badly damaged filesystems.
4886 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4887 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4888 large file when deciding whether or not the filesystem has large files.
4890 Fixed lsattr and chattr so that they work correctly on large files.
4891 (Fixes Debian bug #72690.)
4893 Removed limitation in get_device_size() which imposed a one terrabyte
4894 filesystem limitation. (Most 2.2 kernels still have a signed int
4895 problem which cause 1 TB block device limitation. Fortunately, the
4896 kernel patches to fix this are much easier than fixing the 2TB
4897 limitation in the kernel. :-)
4899 A max_mount_count of zero is now treated as if no mount count were
4900 set. (Previously, no mount count was indicated by using -1, and a
4901 mount count of zero caused e2fsck to always be run.)
4903 Mke2fs supports two new filesystem types largefile and largefile4.
4905 Mke2fs now adds some randomness in s_max_mount_count so that multiple
4906 filesystems won't be all checked at the same time under normal
4909 Fixed bug in the progress bar printing code which could cause e2fsck
4910 to core dump on an illegal filesystem.
4912 Fixed bug in fsck which could allow more than one instance of e2fsck
4913 to be printing a progress bar. (Debian bug #65267)
4915 Fsck using a UUID or a LABEL specifier will work even if devfs is
4916 compiled into the kernel and not mounted. If the pathnames in
4917 /proc/partitions are incorrect, fsck will search /dev for the correct
4918 device (using the new ext2fs_find_block_device library function).
4919 Fsck now also checks the RAID devices first so that they are properly
4920 found when they are in use. Support has also been added to support
4921 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4923 Fixed a bug in fsck which caused it not deal properly with 16
4924 byte long filesystem labels.
4926 Fsck's -t option has been made a lot more flexible. The semantics for
4927 what happens if a comma-separated list to fsck has been regularized,
4928 and it is now possible to filter what filesystems will get checked
4929 based what is in the filesystem's fstab entry's option field. (Debian
4932 The dumpe2fs program can now print out the group description
4933 information in hex, and also prints the location of the superblock and
4934 block group descriptor for those block groups that have them.
4936 Mke2fs now clears the ext2 superblock before it starts creating a
4937 filesystem, so that the superblock magic number is only written if the
4938 filesystem creation process successfully completes.
4940 The debugfs program's stat command now pretty-prints the blocks used
4941 by an inode so that it's more compact and informative.
4943 The debugfs stats command now uses the same libe2p code (which is used
4944 by dumpe2fs) to print the superblock header information. This is more
4945 complete, and it avoids a bit of code duplication.
4947 Added a new debugfs command, set_super_value (ssv) which allows the
4948 user to set arbitrary superblock fields.
4950 Debugfs was extended to support inode numbers in hex (by prefixing
4951 them with 0x), and so that modify_inode can set the inode generation
4952 number. Also, there is now a new function command called logdump
4953 which will dump an ext3 journal.
4955 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4958 Debugfs's dump command now stops immediately upon reporting a disk
4959 read error. (Fixed a bug in ext2fs_file_read library routine which
4960 caused debugfs not to stop.) (Debian bug #79163)
4962 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4963 checked before /etc/mtab is used, since /proc/mounts is more likely to
4966 Added portability fixes for Solaris and Linux/ia64.
4968 Various manual pages were clarified and cleaned up. (Fixed debian
4969 bugs #63442, #67446, and #87216)
4975 The e2fsck message printer now supports %Iu and %Ig, which will print
4976 out the inode's user and group owners, respectively.
4978 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4979 that no longer dependent on the system having the correct version of
4980 the kernel header files.
4982 Added a new function to libext2, ext2fs_find_block_device(), which
4983 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4984 device given its device number.
4986 Added a new function to libext2, ext2fs_sync_device, which centralizes
4987 all of the places which might try to use the BLKFLSBUF or FDFLUSH
4988 ioctls (and usually failing to define them since the system header
4989 files don't usually do this for us, and we're trying to avoid usage of
4990 kernel include files now).
4992 Added new utility programs in tests/progs: random_exercise and
4993 hold_inode. They aren't built by default; they're useful for
4994 exercising ext3 filesystem code.
4996 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4997 the filesystem close functions to only update the superblock, and to
4998 not touch the block group descriptors. Needed by tune2fs when
4999 modifying a mounted filesystem.
5001 Got rid of struct ext2fs_sb and replaced it with the standard struct
5002 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
5003 source (but not binary) compatibility of some users of the ext2
5004 library. Those applications should just simply do a global search and
5005 replace of struct ext2fs_sb with struct ext2_super_block, and include
5006 the new header file <ext2fs/ext2_fs.h> which defines it.
5008 The ino_t type has been renamed ext2_ino_t to protect applications
5009 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5010 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
5011 unexpected ABI change.
5013 The Makefiles have been reworked so that "make check" can be run from
5014 the top-level Makefile.
5016 Fix general gcc -Wall complaints and removed dead code.
5018 Remove use of NOARGS, because we assume everyone does ANSI C these
5021 Added build-rpm script from sct.
5023 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
5026 New function ext2fs_flush_icache which must be called if the
5027 application program modifies the inode table blocks without going
5028 through ext2fs_write_inode() interface.
5030 New ext2fs_check_mount_point() function, which will return the mount
5031 point of a device if mounted.
5033 The io_channel abstraction now has an optional interface,
5034 io_channel_write_range, which allows specific byte ranges to be
5037 The unix_io IO channel now supports write-through caching, so that
5038 journal creation is more efficient.
5040 Added x86 assembly language routines to support byte swapping, to
5041 reduce executable size.
5043 Fixed bug in the utility program subst so that it's possible to
5044 replace a substitution variable with a zero-length string.
5046 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5047 slipped into some of the problem number.
5049 E2fsprogs 1.19 (July 13, 2000)
5050 ==============================
5052 Release the resize2fs program since the timeout before it could
5053 be released under the GPL has finally expired.
5055 Add experimental support needed for the ext2 compression patches.
5056 This requires compiling e2fsprogs with the --enable-compression flag
5057 to the configure script.
5059 Added ext3 journalling support. E2fsck will run the journal (if
5060 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
5061 installed as a symlink to e2fsck. Fsck has been taught about ext3,
5062 and treats it the same as ext2 in terms of the progress bar logic.
5063 Dumpe2fs will display the superblock journaling information if the
5064 filesystem has a journal. The ext2 library will now permit opening an
5065 ext3 filesystem with the recovery flag set. This is necessary for
5066 on-line dump's to work correctly, but there may be issues with this
5067 working well since ext3 is much less agressive about syncing blocks to
5068 the filesystem, since they're safe on the journal.
5070 Tune2fs and e2fsck have been changed to allow the mount_count check to
5071 be disabled by setting max_mount_count to -1. (This was already
5072 supported by the kernel.)
5074 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5075 are used for ext3 as well.
5077 Added internationalization support for e2fsprogs; must be enabled
5078 by passing --enable-nls to configure.
5080 Always use the provided ext2fs header files to insulate ourselves from
5081 kernel version changes. Which include files are used by e2fsprogs
5082 have also been cleaned up to improve portability.
5084 Limit the number of times that e2fsck updates the progress bar so that
5085 people who are booting using a 9600 baud console don't get swampped by
5088 Improved the loop detection algorithm in e2sck's pass #3 so that it is
5089 much, much faster for large filesystems with a large number of
5092 The memory footprint for e2fsck is now slightly smaller than before.
5094 E2fsck now checks if special devices have a non-zero size, and offers
5095 to clear the size field if it finds such an inode.
5097 E2fsck now checks if special devices have the append-only flag set,
5098 and offers to clear the inode.
5100 E2fsck now properly handles some "should never fail" cases during a
5101 bitmap copy in pass5.
5103 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5105 E2fsck now calculates the correct location of the backup superblock in
5106 the case of filesystem blocksizes > 1k.
5108 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5109 which normally didn't cause problems under most filesystem parameters,
5110 but could cause a valid superblock to be rejected in extreme cases.
5111 Other checks for validating superblock values were made more
5114 Added non-destructive write testing to the badblocks program, courtesy
5115 of David Beattie. The badblocks also now has an option to input the
5116 current set of bad blocks, so that known bad blocks are skipped to
5117 speed up the badblocks test. There is also a persistent rescan
5118 feature which causes badblocks to run until it has completed some
5119 number of passes without discovering any new bad blocks.
5121 Badblocks now checks to see if the device is mounted and refuses to do
5122 the tests involving writing to the device if it is mounted. Also,
5123 badblocks now allows the number of blocks to be checked to be
5124 defaulted to the size of the partition.
5126 Fixed a bug in fsck which didn't allow non-root users to be able to
5127 check filesystems if there were any LABEL= or UUID= entries in
5130 The Hurd doesn't support the filetype filesystem feature. The mke2fs
5131 program now makes sure that for the Hurd, the filestype feature is
5132 turned off. E2fsck will check to see if the filetype feature is
5133 turned on for Hurd filesystems, and offer to turn off the feature.
5135 Mke2fs now has a safety check to make sure the number of blocks do not
5136 exceed 32 bits even on a 64 bit platform.
5138 Really fixed a bug in fsck to allow "fsck -As" to run interactive
5139 fsck's. (For those people who like to do interactive fsck's in the
5142 Debugfs has a few new features: the rdump command, which will do a
5143 recursive dump of a directory and all of its contents, and the lcd
5144 command which does a local chdir (much like the ftp command of the
5145 same name). In addition, the debugfs program and the open_filesystem
5146 command now takes three new options: -b and -s, which allows the
5147 blocksize and superblock location to be specified, and the -c option
5148 which is used in catastrophic situations where the block group
5149 descriptors are corrupt. If the -c option is specified, debugfs will
5150 skip trying to read in the block and inode bitmaps.
5152 Debufs's lsdel command was fixed to handle bad blocks in the inode
5155 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
5158 General improvements in error messages
5160 - Mke2fs prints a sane error message if the partition size is zero
5161 (usually because the partition table wasn't reread by the
5162 kernel due to the partition being busy), instead of "invalid
5163 argument passed to ext2 library while initializing superblock".
5165 - Fsck now prints more self-explanatory message if an invalid UUID=
5166 or LABEL= specification is passed to it.
5168 UUID library changed to use the LGPL.
5170 Fixed a bug in the UUID library where very rapid calls to the
5171 time-based UUID generator could cause duplicate UUID's to be returned.
5172 This was not a problem for e2fsprogs, but it could be a problem for
5173 other users of the library.
5175 Make the UUID library more robust in the face of missing or an
5176 improper /dev/urandom or /dev/random files.
5178 Added some random portability fixes for Solaris.
5180 Some minor man page updates.
5182 Fixed a memory leak in the ss library.
5188 We now try to use lseek64 and open64 from the LFS if possible.
5190 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5193 The mark and unmark bitmap functions now return the previous state of
5194 the bit that was being changed, which is useful for some speed
5197 The following functions have been added to enhance the badblocks list
5198 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5199 ext2fs_badblocks_equal.
5201 The ext2 header files now have the latest journalling fields to the
5204 The ext2fs_mkdir function in libext2fs now properly backs out of error
5205 conditions robustly.
5207 Cleaned up makefiles:
5208 - to cleanly compile with the -j flag.
5209 - so distclean removes all generated files.
5210 - so in case of an error while installing header files, the make aborts.
5212 Fix test_script so that it works correctly when compiling in the
5215 The random UUID generation routine has been made slightly better in
5216 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5217 is still not recommended if /dev/random doesn't exist, however; it's
5218 better to use the time/ethernet MAC address UUID in this case.)
5220 Clean up the build process so it's more friendly in case of missing
5223 The ext2fs header file can now be #include'd into C++ programs.
5225 The e2p.h header file is now installed.
5227 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5231 E2fsprogs 1.18 (November 10, 1999)
5232 ==================================
5234 Fix a core dumping bug in e2fsck if an imagic inode is present or
5235 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5236 has to restart pass 1 processing. E2fsck now closes the filesystem
5237 before freeing a large number of its data structures, so in the case
5238 of future memory faults, at least the fixed filesystem will be fully
5241 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5242 imagic inode, it will offer to clear the imagic flag.
5244 E2fsck will now offer to clear the immutable flag on special files
5245 (device/socket/fifos) when running it in non-preen mode.
5247 E2fsck will now set the filetype when creating /lost+found, and when
5248 connected orphaned inodes to /lost+found.
5250 Debugfs's ncheck and icheck commands now handles the case where there
5251 are bad blocks in the inode table without bombing out.
5253 The badblocks list processing code has been made more efficiently for
5254 appending a large number of (ordered) badblocks to the badblocks list.
5256 Some minor man page updates.
5258 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5259 mode, but some people like to do this in boot scripts for silly reasons).
5264 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5265 with the problem code convention.
5267 The badblocks list regression test program has been updated to work
5268 with previously made API name changes.
5270 The ext2fs_free() command now uses the new badblocks API to avoid
5271 using the compatibility layer.
5273 Added new regression test cases; the run_e2fsck test script now
5274 supports the ability for a test case to run a prepratory command
5275 before running e2fsck.
5277 E2fsprogs 1.17 (October 26, 1999)
5278 =================================
5280 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5283 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5284 thus potentially causing problems if a binary UUID contained a NULL
5287 E2fsck now uses stricter checks for directory entries in pass 2:
5288 zero-length filenames are not allowed; neither are 8 byte long
5291 The debugfs "dirty" command now clears the filesystem valid bit.
5292 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5293 bit in the in-core superblock image. The new functionality is more
5294 what the user expects, and is more useful.)
5296 Added a debugging hook to test parallel fsck; if the environment
5297 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5298 will be checked in parallel when they normally would not be.
5303 Fixed some #ifdef's for compilation under the Hurd OS.
5305 Fixed minor W2K compatibility problems.
5307 Fixed some miscellaneous GCC warnings.
5310 E2fsprogs 1.16 (October 22, 1999)
5311 =================================
5313 Fixed a race condition bug in fsck; when printing a progress bar, if
5314 checking multiple filesystems in parallel, it was possible for fsck to
5315 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5316 handler, which would cause it to terminate with a signal 10.
5318 E2fsck now properly handles filesystems that have the
5319 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5320 filesystem into using or not using FILETYPE feature.
5322 E2fsck now properly handles filesystems that have the IMAGIC feature
5323 turned on (this is used on Linux AFS servers).
5325 The mke2fs program now creates filesystems that have the filetype and
5326 sparse_superblock features enabled by default, unless it is run on a
5327 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5328 so there is now a new flag -O which allows the user to specify with
5329 which features she would like to create the filesystem; "mke2fs -O
5330 none" will create a filesystsem compatible with 2.0 kernels.
5332 The tune2fs program now has a -O option which allows the user to set
5333 and reset "safe" filesystem features. Currently, the only ones which
5334 allows to be modified are the filetype and sparse_superblock features.
5335 Note setting or clearing either feature will require running e2fsck on
5336 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5337 requires that there is enough free space on the filesystem for the
5338 extra superblocks which will be created by e2fsck.)
5340 Debugfs can now set and print filesystem features in the superblock
5341 using the "features" command. Dumpe2fs will print out the complete
5342 set of features when listing the superblock.
5344 Dumpe2fs has new options -f (force) and -h (header-only).
5346 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5347 message to come up. This could happen when decrementing or
5348 incrementing a link count could result in an overflow.
5350 Fixed a bug in e2fsck where the block count on the lost+found
5351 directory would not be properly incremented when the directory was
5352 expanded to the point where an indirect block needed to be allocated.
5354 E2fsck now makes some additional sanity checks on the superblock to
5355 avoid crashing or giving a memory allocation error if some of the
5356 values in the superblock are unresonable (but the superblock otherwise
5359 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5360 require two passes to completely fix the filesystem. This happened if
5361 an inode claimed blocks that was part of the filesystem metadata
5362 (typically, when garbage was written into an inode table or indirect
5363 block, since this kind of filesystem corruption normally doesn't
5366 On the Alpha, glibc declares st_flags although it isn't actually used;
5367 the configure script was improved to detect this case so that
5368 e2fsprogs can avoid using the non-functional stat field.
5370 The manual pages were updated to use a more consistent formatting
5371 style consistent with standard Unix man pages. Mke2fs's man page
5372 added documentation for a few previously undocumented options.
5374 Fixed minor display bugs in tune2fs and mke2fs.
5379 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5381 Added features to parse and print feature strings into the e2p library.
5382 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5384 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5385 whose directory entries contain proper filetype information if the
5386 filesystem supports it.
5388 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5389 the directory entry filetype information. This is used to set the
5390 directory entry filetype information if the filesystem supports it.
5392 Fixed a bug in ext2fs_expand_dir() where the block count in a
5393 directory's inode would not be properly incremented when the directory
5394 was expanded to the point where an indirect block needed to be
5398 E2fsprogs 1.15 (July 18, 1999)
5399 ==============================
5401 Add configuration checks so that e2fsprogs will compile cleanly on
5402 Linux 2.3 kernels that have renamed i_version to i_generation.
5404 E2fsck now prints a progress/completion bar (and not just a simple
5405 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5406 signal. Fsck will automatically manage the (potentially muliple)
5407 e2fsck processes to print completion bars if it is given a -C option,
5408 with the right thing happening if multiple filesystems are being
5409 checked in parallel.
5411 Mke2fs now has better automatic hueristics to determine the filesystem
5412 parameters to be used for a particular filesystem. Added a new option
5413 -T which allows the user to specify how the filesystem is to be used,
5414 which helps mke2fs do a better job selecting the filesystem parameters.
5416 Mke2fs now creates revision 1 filesystems by default, and with the
5417 sparse superblock feature enabled. The sparse superblock feature is
5418 not understood by Linux 2.0 kernels, so they will only allow read-only
5419 mounts of filesystems with this sparse superblocks.
5421 Fix bug where if /dev/null couldn't be opened (should never happen),
5422 e2fsck would hang in a tight loop.
5424 Make e2fsck handle the case where /lost+found isn't a directory.
5426 E2fsck now uses mallinfo if it exists to get accurate statistics about
5429 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5430 inode had any problems before connecting it to /lost+found.
5432 Add check to e2fsck so it makes sure that total number of inodes in
5433 the filesystem is a sane number.
5435 Fix fencepost error when clearing an the end of the block bitmap which
5436 caused the last block in the bitmap not to get cleared.
5438 Cleaned up a number of messages in e2fsck:
5439 * The message "Group's #'s copy of the group descriptor..."
5440 was fixed so that the correct number would be displayed.
5441 * Added missing space in the "disk write-protected" error messsage
5442 * Cleaned up the error message printed when a non-interactive
5443 e2fsck needs to abort a check because the filesystem
5444 appears to be mounted.
5446 Added a new command-line utility, uuidgen, which will create and print
5449 Make debugfs's icheck command more robust by checking to make sure an
5450 inode has valid blocks before interarting over the inode's blocks.
5452 UUID generation now uses a random-based scheme whenever possible to
5453 prevent potential privacy problems.
5455 Man pages for all of the UUID functions in the lirbary were added.
5457 Fixed bug in fsck so it won't coredump if a filesystem not in
5458 /etc/fstab is given to it.
5460 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5461 that most of the other mount utilities understands.
5463 Mke2fs will make a filesystem even if it appears mounted if the force
5466 Dumpe2fs has new command-line options which allow a filesystem expert
5467 to specify the superblock and blocksize when opening a filesystem.
5468 This is mainly useful when examining the remains of a toasted
5471 The badblocks program has been updated to display correctly on disks
5472 with large block numbers.
5474 The badblocks program no longer gives spurious errors when errors
5475 occur on non-block boundaries, which is common if the blocksize is
5478 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5479 MKE2FS_SYNC environment variable is set. This is to work around a VM
5480 bug in the 2.0 kernel. I've heard a report that a RAID user was able
5481 to trigger it even using a 2.2 kernel, but hopefully it will not be
5482 needed for most Linux 2.2 users.
5484 Fixed miscellaneous documentation and man pages.
5489 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5490 in e2fsck's pass1.c really should have been static.
5492 The return value of the uuid_compare() function was changed to make it
5493 match with the convetions used by strcmp, memcmp, and Paul Leach's
5494 UUID sample document.
5496 The "make depend" process has now been made more automated; it now
5497 automatically word-wraps the dependencies, and only replaces source
5498 Makefile.in if there has been a change in the dependencies. Also, a
5499 top-level "make depend" now recurses through all the subdirectories
5502 The Makefile in .../util has been changed so that subst is built using
5503 the native C compiler during a cross-compilation, since the subst
5504 program is only used during the build process. Also add an explicit
5505 rule to build util/subst by cd'ing to the correct directory and
5508 The man directories are defined in terms mandir, so that the configure
5509 script can override the location of the manual pages.
5511 The config files have been updated to recognize new machine types for
5512 both the i386 and alpha families.
5514 Fsck has been modified so that it will accurately create an
5515 fsck_instance even when the noexecute flag is set. This allows for
5516 accurate debugging of the fsck pass structure. Also, when the verbose
5517 flag is given twice, fsck will print debugging information about when
5518 fsck is waiting for jobs to finish.
5521 E2fsprogs 1.14 (January 9, 1999)
5522 ================================
5524 Fix the fstab parsing code so that it can handle blank lines and
5525 comment characters. Also, missing pass numbers need to be treated as
5528 Fixed a bug in e2fsck where under some circumstances (when e2fsck
5529 needs to restart processing after fixing an egregious inconsistency)
5530 it would try to access already freed memory.
5532 E2fsck now prints non-printable characters in directory entries and
5533 pathnames using '^' and 'M-' notation.
5535 Fixed chattr so that it will ignore symbolic links when doing
5536 recursive descent traversals. For both chattr and lsattr, no longer
5537 print the version string unless the -V option is given.
5539 Allow the system administrator to directly specify the number of
5540 inodes desired in the filesystem, for some special cases where this is
5543 Fix portability problems so that e2fsprogs can be compiled under Linux
5544 1.2 systems and Solaris systems.
5546 Update the config.guess file with a more recent version that will
5547 identify newer Linux platforms.
5552 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5553 an inode number of zero is passed to them.
5555 E2fsprogs 1.13 (December 15, 1998)
5556 ==================================
5558 Fixed a bug in debugfs where an error messages weren't getting printed
5559 when the ext2 library routines to read inodes returned errors in the
5560 stat, cmri and rm commands.
5562 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5563 provided, it won't create an inode table smaller than the minimum
5564 number of inodes required for a proper ext2 filesystem.
5566 Fsck now parses the /etc/fstab file directly (instead of using
5567 getmntent()), so that it can distinguish between a missing pass number
5568 field and pass number field of zero. This caused problems for
5569 diskless workstations where all of the filesystems in /etc/fstab have
5570 an explicit pass number of zero, and fsck could not distinguish this
5571 from a /etc/fstab file with missing pass numbers.
5573 E2fsck will create a /lost+found directory if there isn't one in the
5574 filesystem, since it's safer to create the lost+found directory before
5577 Fixed e2fsck so that it would detect bogus immutable inodes which
5578 happen to be sockets and FIFO files, and offer to clear them.
5580 If a filesystem has multiple reasons why it needs to be checked, and
5581 one of the reasons is that it is uncleanly mounted, e2fsck will print
5582 that as the reason why the filesystem is being checked.
5584 Cleaned up the output routines of mke2fs so that it doesn't overflow
5585 an 80 column display when formating really big filesystems.
5587 Added a sanity check to e2fsck to make sure that file descriptors 0,
5588 1, 2 are open before opening the hard disk. This avoids a problem
5589 where a broken program might exec e2fsck with those file descriptors
5590 closed, which would cause disastrous results if the kernel returns a
5591 file descriptor for the block device which is also used by FILE *
5594 Fixed up the e2fsck progress reporting functions so that the values
5595 reliably reach 100% at the completion of all of the e2fsck passes.
5597 Fixed minor documentation bugs in man pages and usage messages.
5602 Fixed a number of lint warnings in the ext2fs library and potential
5603 portability problems from other OS's header files that might define
5604 CPP macros for names like "max" and "min".
5606 ext2fs_badblocks_list_add() has been made more efficient when it needs
5607 to grow the bad blocks list.
5609 Fixed a bug in e2fsck which caused it to dereference a freed pointer
5610 just before exiting.
5612 Fixed the substition process for generating the mk_cmds and compile_et
5613 scripts so that they will work outside of the build tree.
5615 Add sanity check to e2fsck so that if an internal routine
5616 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5617 and causing a core dump. This should never happen, but...
5619 E2fsprogs 1.12 (July 9, 1998)
5620 ==================================
5622 E2fsprogs now works with glibc (at least with the version shipped wtih
5623 RedHat 5.0). The ext2fs_llseek() function should now work even with
5624 i386 ELF shared libraries and if llseek() is not present. We also
5625 explicitly do a configure test to see if (a) llseek is in libc, and
5626 (b) if llseek is declared in the system header files. (See standard
5627 complaints about libc developers don't understand the concept of
5628 compatibility with previous versions of libc.)
5630 The ext2fs library now writes out the block group number in each of
5631 the superblock copies. This makes it easier to automatically
5632 determine the starting block group of the filesystem when the block
5633 group information is trashed.
5635 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5636 which means that e2fsprogs will ignore the high 8 bits of the
5637 directory entry's name_len field, so that it can be used for other
5640 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5641 E2fsprogs will now support filesystems with 64-bit sized files.
5643 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5645 Added new program "e2label", contributed by Andries Brouwer. E2label
5646 provides an easy-to-use interface to modify the filesystem label.
5648 Fixed bug so that lsattr -v works instead of producing a core dump.
5650 Fixed a minor bug in mke2fs so that all groups with bad superblock
5651 backup blocks are printed (not just the first one).
5653 Mke2fs will check the size of the device, and if the user specifies a
5654 filesystem size larger than the apparent size of the device it will
5655 print a warning message and ask if the user wants to proceed.
5657 E2fsck has a new option -C, which sends completion information to the
5658 specified file descriptor. For the most part, this is intended for
5659 programs to use, although -C 0 will print a spinning character to the
5660 stdout device, which may be useful for users who want to see something
5661 happening while e2fsck goes about its business.
5663 Fixed a bug in e2fsck which could cause a core dump when it needs to
5664 expand the /lost+found directory, and sometimes the bitmaps haven't
5665 been merged in. Also fixed a related bug where ext2fs_write_dir_block
5666 was used to write out a non-directory block. (Which would be bad on a
5667 non-Intel platform with byte swapping going on.)
5669 Fixed bug in e2fsck where it would print a "programming error" message
5670 instead of correctly identifying where a bad block was in used when
5671 the bad block was in a non-primary superblock or block group
5672 descriptor. Also fixed a related bug when sparse superblocks are in
5673 use and there is a bad block where a superblock or block group
5674 descriptor would have been in a group that doesn't include a
5677 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5678 the block group descriptor table is corrupt, it was possible to try to
5679 allocate a huge array, fail, and then abort e2fsck.
5680 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5681 and subsitutes reasonable values if the descriptors are obviously bogus.
5683 If e2fsck finds a device file which has the immutable flag set and the
5684 i_blocks beyond the normal device number are non-zero, e2fsck will
5685 offer to remove it, since it's probably caused by garbage in the inode
5688 When opening a filesystem, e2fsck specially checks for the EROFS error
5689 code, and prints a specific error message to the user which is more
5692 If the filesystem revision is too high, change the e2fsck to print
5693 that this is either because e2fsck is out of date, or because the
5694 superblock is corrupt.
5696 E2fsck now checks for directories that have duplicate '.' and '..'
5697 entries, and fixes this corruption.
5699 E2fsck no longer forces a sync of the filesystem (with attendant sleep
5700 calls) at all times. The ext2fs_flush() function now performs a sync
5701 only if it needed to write data blocks to disk.
5703 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5704 certain errors would not be properly reported.
5706 Updated and expanded a few points in the man pages which users
5707 complained wheren't explicit enough.
5709 Added special case byte-swapping code if compiling on the PowerPC, to
5710 accomodate the strange big-endian variant of the ext2 filesystem that
5711 was previously used on the PowerPC port.
5717 Removed C++ keywords from the ext2fs libraries so that it could be
5720 E2fsck's internal organization has now been massively reorganized so
5721 that pass*.c don't have any printf statements. Instead, all problems
5722 are reported through the fix_problem() abstraction interface. E2fsck
5723 has also been revamped so that it can be called as a library from a
5726 Added new fileio primitives in libext2fs for reading and writing
5727 files on an unmounted ext2 filesystem. This interface is now used by
5730 Added a new libext2fs function for mapping logical block numbers of
5731 a file to a physical block number.
5733 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5734 a block, zeros it, and updates the filesystem accounting records
5737 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5738 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5740 The libext2fs functions now use a set of memory allocation wrapper
5741 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5742 instead of malloc, free, and resize. This makes it easier for us to
5743 be ported to strange environments where malloc, et. al. aren't
5744 necessarily available.
5746 Change the libext2fs fucntion to return ext2-specific error codes
5747 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5748 and depending on the existence of system error codes (such as EEXIST
5751 Renamed io.h to ext2_io.h to avoid collision with other OS's header
5754 Add protection against ext2_io.h and ext2fs.h being included multiple
5757 The types used for memory lengths, etc. have been made more portable.
5758 In generla, the code has been made 16-bit safe. Added Mark
5759 Habersack's contributed DOS disk i/o routines.
5761 Miscellaneous portability fixes, including not depending on char's
5764 The io_channel structure has a new element, app_data, which is
5765 initialized by the ext2fs routines to contain a copy of the filesystem
5768 ext2fs_check_directory()'s callback function may now return the error
5769 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5770 really do the checking, despite the presence of the callback function.
5773 E2fsprosg 1.11 (June 17, 1997)
5774 ==============================
5776 Fixed e2fsck to detect (previously ignored) conflicts between the
5777 superblock or block group descriptors and block bitmaps, inode
5778 bitmaps, and inode tables.
5780 Fixed bug in e2fsck so that when the message printed out when a block
5781 or inode bitmap conflicts with other data, it has the correct group
5784 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5785 to badblocks. This meant that not all of the filesystem was being
5786 tested for bad blocks!
5788 Fixed an array boundary overrun case which cropped up in
5789 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5792 Adjusted the number of columns printed by mke2fs when displaying the
5793 superblock backups to avoid running over 80 columns when making a
5794 really big filesystem.
5796 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5797 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5798 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5803 Fixed install rule in lib/ss so that ss_err.h is actually getting
5806 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5807 bassed back to the caller.
5809 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5810 setting the current inode number (which meant this function wasn't
5813 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5814 blocks in the bitmap when increasing the size of the bitmap.
5816 Changed the initial number of blocks allocated by ext2fs_init_dblist()
5817 to be more realistic.
5819 Added a new function ext2fs_allocate_group_table, which sets up the
5820 group descriptor information (and allocates inode and block bitmaps,
5821 and inode tables for a particular group). The function was created by
5822 factoring out code form ext2fs_allocate_tables().
5824 Added a new function ext2fs_move_blocks which takes a bitmap of the
5825 blocks to be moved, and moves them to another location on the
5828 Make the unix_io channel's io_channel_flush implementation calls sync()
5829 to to flush the kernel buffers to disk.
5831 Added a new function ext2fs_dblist_count returns the number of
5832 directory blocks in dblist.
5835 E2fsprogs 1.10 (April 24, 1997)
5836 ===============================
5838 Mke2fs once again defaults to creating revision #0 filesystems, since
5839 people were complaining about breaking compatibility with 1.2 kernels.
5840 Warning messages were added to the mke2fs and tune2fs man pages that
5841 the sparse superblock option isn't supported by most kernels yet (1.2
5842 and 2.0 both don't support parse superblocks.)
5844 Added new flag to mke2fs, -R <raid options>, which allows the user to
5845 tell mke2fs about the RAID configuration of the filesystem. Currently
5846 the only supported raid option is "stride" which specifies the width
5849 Fixed bug in e2fsck where pass1b would bomb out if there were any
5850 blocks marked bad in the inode table.
5852 Fixed rare bug in mke2fs where if the user had a very unlucky number
5853 of blocks in a filesystem (probability less than .002) the resulting
5854 filesystem would be corrupt in the last block group.
5856 Fixed bug where if e2fsck tried to allocate a block to fix a
5857 filesystem corruption problem and the filesystem had no free blocks,
5858 ext2fs_new_block() would loop forever.
5860 The configure script now checks explicitly to see if "-static" works,
5861 since that can't be assumed to be true --- RedHat doesn't install
5862 libc-static by default.
5864 Fixed bug in libext2's block iterator functions where under some
5865 cirmcustances, file with holes would cause the bcount parameter to the
5866 callback function to be incorrect. This bug didn't affect any of
5867 e2fsprogs programs, but it was discovered by Paul Mackerras, the
5868 author of the PPC boot loader.
5870 Removed use of static variables to store the inode cache in libext2fs.
5871 This caused problems if more than one filesystem was accessed via
5872 libext2fs (static variables in libraries are generally a bad idea).
5873 Again, this didn't affect e2fsprogs programs, but it was discovered by
5876 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5877 will compile cleanly with 1.2.13 kernels (even with a.out shared
5883 Added new functions to duplicate an ext2 filesystem handle, and its
5884 associated substructure. New functions: ext2fs_dup_handle(),
5885 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5886 Other structures, such as the io_channel and the inode_cache, now have
5887 a ref count so that they only get freed when they are no longer used
5888 by any filesystem handle. (These functions were added as part of the
5889 development effort for an ext2 resizer).
5891 E2fsprogs 1.09 (April 14, 1997)
5892 ===============================
5894 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5895 accidentally introduced in the 1.08 release. The overhead calculation
5896 was accidentally removed, which caused ext2fs_initialize() to not
5897 notice when the filesystem size needed to be adjusted down because
5898 there wasn't enough space in the last block group.
5900 Fixed bug in version parsing library routine; it was always parsing
5901 the library version string, instead of using the passed-in string.
5903 Clarified chattr man page.
5905 E2fsprogs 1.08 (April 10, 1997)
5906 ===============================
5908 E2fsck 1.07 was very slow when checking very large filesystems with a
5909 lot of files that had hard links (i.e., news spools). This was fixed
5910 by seriously revamping the icount abstraction. Added a formal test
5911 suite for the icount abstraction.
5913 Debugfs now has a "-l" option to the "ls" command, which lists the
5914 inode number, permissions, owner, group, size, and name of the files
5917 Fix a bug in e2fsck where when a directory had its blocks moved to
5918 another location during the pass 1b processing, the directory block
5919 list wasn't updated, so pass 2 wouldn't check (and correct) the
5920 correct directory block.
5922 E2fsck will now treat inodes which contain blocks which are claimed by
5923 the filesystem metadata by treating them as multiply claimed blocks.
5924 This way, the data in those blocks can be copied to a new block during
5925 the pass 1b--1d processing.
5927 E2fsck will attempt to determine the correct superblock number and
5928 display it in the diagnostic and warning messages if possible.
5930 Add support for a new (incompatible) feature, "sparse_super". This
5931 feature reduces the number of blocks which contain copies of backup
5932 superblocks and block group descriptors. (It is only an incompatible
5933 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5934 support a new -s option; e2fsck will recognize filesystems built with
5935 this feature turned on.
5937 E2fsck now checks the library to make sure is the correct version,
5938 using new library functions. (This helps to diagnose incorrectly
5939 installed e2fsprogs distributions.)
5941 Dumpe2fs now prints more information; its now prints the the
5942 filesystem revision number, the filesystem sparse_super feature (if
5943 present), the block ranges for each block group, and the offset from
5944 the beginning of the block group.
5946 Mke2fs now distributes the inode and block bitmap blok so that the
5947 won't be concentrated in one or two disks in RAID/striping setups.
5948 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5949 choose the largest blocks per group that be chosen. (For 2k blocks,
5950 you can have up to 16384 blocks/group; for 4k blocks, you can have up
5951 to 32768 blocks/group.) Previously mke2fs would not allow
5952 specification of more than 8192 blocks per group, even if you were
5953 using a 2k or 4k block group.
5958 Added a new function ext2fs_create_icount2() which takes a "hint"
5959 argument. This hint argument presets the icount array with the list
5960 of inodes which actually need to be in the icount array. This really
5961 helps to speed up e2fsck.
5963 Added a new function ext2fs_icount_validate() which checks the rep
5964 invariant for the icount structure. This is used mostly for testing.
5966 The error mesasage given when a bad inode number is passed to
5967 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5968 EXT2FS_UNMARK_ERROR).
5970 Added a new function ext2fs_set_dir_block which sets the block of a
5971 dblist entry, given the directory inode and blockcnt.
5973 Added a new function ext2fs_get_library_version() which returns the
5974 current library version, and ext2fs_parse_version_string() which
5975 returns a version number based on a e2fsprogs version string.
5977 The icount functions will return EINVAL if the passed in inode number
5980 E2fsprogs 1.07 (March 9, 1997)
5981 ==============================
5983 E2fsck is now uses much less memory when checking really large
5984 filesystems (or rather, filesystems with a large number of inodes).
5985 Previously a filesystem with 1 million inodes required 4 megabytes of
5986 memory to store inode count statistics; that storage requirement has
5987 now been reduced to roughly half a megabyte.
5989 E2fsck can now properly deal with bad blocks appearing inside the
5990 inode table. Instead of trying to relocate the inode table (which
5991 often failed because there wasn't enough space), the inodes in the bad
5992 block are marked as in use.
5994 E2fsck will automatically try to use the backup superblocks if the
5995 primary superblocks have a bad magic number or have missing meta-data
5996 blocks (or meta-data blocks which are out of range).
5998 E2fsck's pass 3 has been made more efficient; most noticeable on
5999 filesystems with a very large number of directories.
6001 Completely revamped e2fsck's system of printing problem reports. It
6002 is now table driven, to make them more easily customizeable and
6003 extendable. Error messages which can be printed out during preen mode
6004 are now one line long.
6006 Fixed e2fsck's filesystem swapping code so that it won't try to swap
6007 fast symbolic links or deleted files.
6009 Fixed e2fsck core dumping when fixing a filesystem which has no
6010 directories (not even a root directory).
6012 Added a check to e2fsck to make sure that the length of every
6013 directory entry is a multiple of 4 (since the kernel complains if it
6016 Added a check to e2fsck to make sure that a directory entry isn't a
6017 link to the root directory, since that isn't allowed.
6019 Added a check to e2fsk to now make sure the '.' and '..' directory
6020 entries are null terminated, since the 2.0 kernel requires it.
6022 Added check to write_bitmaps() to make sure the superblock doesn't get
6023 trashed if the inode or block bitmap is marked as being block zero.
6025 Added checking of the new feature set fields in the superblock, to
6026 avoid dealing with new filesystem features that this package wasn't
6029 Fixed a fencepost error in ext2fs_new_block() which would occasionally
6030 try to allocate a block beyond the end of a filesystem.
6032 When the UUID library picks a random IEEE 802 address (because it
6033 can't find one from a network card), it sets the multicast bit, to
6034 avoid conflicting with a legitimate IEEE 802 address.
6036 Mke2fs now sets the root directory's owner to be the real uid of the
6037 user running mke2fs. If the real uid is non-zero, it also sets
6038 the group ownership of the root directory to be the real group-id of
6039 the user running mke2fs.
6041 Mke2fs now has more intelligent error checking when it is given a
6042 non-existent device.
6044 When badblocks is given the -vv option, it now updates the block that
6045 it is currently testing on every block.
6047 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6048 currently correctly if PATH wasn't already set.
6050 Shared libraries now built with dependencies. This allows the shared
6051 library files to be used with dlopen(); it also makes the transition
6052 to libc 6 easier, since ld.so can tell which libc a particular shared
6053 library expects to use.
6058 Added new abstraction (defined in dblist.c) for maintaining a list of
6059 blocks which belongs to directories. This is used in e2fsck and other
6060 programs which need to iterate over all directories.
6062 Added new functions which test to see if a contiguous range of blocks
6063 (or inodes) are available. (ext2fs_*_bitmap_range).
6065 Added new function (ext2_inode_has_valid_blocks) which returns true if
6066 an inode has valid blocks. (moved from e2fsck code).
6068 Added new function (ext2fs_allocate_tables) which allocates the
6069 meta-data blocks as part of initializing a filesystem. (moved from
6072 Added a new I/O manager for testing purposes. It will either allow a
6073 program to intercept I/O requests, or print debugging messages to
6074 trace the activity of a program using the I/O manager.
6076 The badblocks_list functions now store the bad blocks in a sorted
6077 order, and use a binary search to speed up badblocks_list_test.
6079 The inode scan function ext2fs_get_next_inode() may now return a soft
6080 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6081 those cases where part of an inode table is missing or there is a bad
6082 block in the inode table.
6084 Added a new function (ext2fs_block_iterate2) which adds new arguments to
6085 the callback function to return a pointer (block and offset) to the
6086 reference of the block.
6088 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6089 application to jump to a particular block group while doing an inode
6092 The badblocks list functions were renamed from badblocks_* to
6093 ext2fs_badblocks_*. Backwards compatibility functions are available
6094 for now, but programs should be modified to use the new interface.
6096 Some of the library functions were reorganized into separate files to
6097 reduce the size of some programs which statically link against the
6100 Put in some miscellaneous fixes for the Alpha platform.
6103 E2fsprogs 1.06 (October 7, 1996)
6104 ================================
6106 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6107 smash the backup copies in ext2fs_close(). (The problem was that when
6108 e2fsck -p discovered the problem, while it was closing the filesystem
6109 and exiting, it was also blowing away the backup superblocks on the
6110 disk, which was less than friendly.) We now make it the case that we
6111 only write out the backup superblock and the back block descriptors if
6112 the filesystem is completely free from problems.
6114 Fixed a bug in block_interate in the lib/ext2fs library which caused
6115 e2fsck to fail on GNU Hurd-created filesystems.
6117 Add support for Linux/FT's bootloader, which actually uses
6118 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6121 Add support for the "A" (no atime update) attribute. (Note: this
6122 attribute is not yet in production kernels.)
6124 The test suite is not automatically run when doing a "make all" from
6125 the top level directory. Users should manually run "make check" if
6126 they wish to run the test suite.
6128 Upon a preenhalt(), make the printed message more explicit that
6129 running e2fsck "MANAULLY" means without the -p or -a options.
6131 In e2fsck, if a disconnected inode is zero-length, offer to clear it
6132 instead of offering to connect it to lost+found.
6134 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6135 e2fsck to be run over it, change e2fsck to explicitly display this
6138 For dumpe2fs and e2fsck, cause the -V option to print out which
6139 version of the ext2fs library is actually getting used. (This will
6140 help detect mismatches of using a 1.06 utility with a 1.05 library,
6146 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6147 the naming convention.
6149 In ext2fs_initialize(), make sure the description for the inode bitmap
6150 is correctly initialize.
6152 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6154 E2fsprogs 1.05 (September 7, 1996)
6155 ==================================
6157 Add support for new fields in the ext2 superblock --- volume name,
6158 volume UUID, and last mounted field. Dumpe2fs displays these fields,
6159 tune2fs and mke2fs allows you to set them. E2fsck will automatically
6160 generate a UUID for those volumes that don't have them.
6162 Put in support for e2fsck to recognize HURD specific ext2 features ---
6163 most notably, the translator block. The e2fsprogs tools will now use
6164 the creator_os field in the superblock to correctly handle different
6165 OS-specific variants of the ext2 filesystem.
6167 E2fsck now fixes inodes which have a the deletion time set, but which
6168 have a non-zero i_link_count field by offering to clear the deletion
6169 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6170 ext2 kernel behavior) and offered to unlink the file.
6172 If e2fsck sets the clean bit, but nothing else, set the exit code
6173 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6174 set the filesystem valid bit when it was previously cleared. :-) This
6175 was needed to make the HURD fsck driver happy.
6177 If the user refuses to attach an unattached inode, e2fsck will no
6178 longer set the inode's link count. Otherwise, the inode would end up
6179 getting marked as unused, which might cause loss of data later.
6181 Make the message issued by e2fsck when the superblock is corrupt less
6182 confusing for users. It now mentions that another reason for the
6183 "corrupt superblock" message might be that the partition might not be
6184 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6186 Make the libext2 library more robuest so that e2fsck won't coredump on
6187 an illegal superblock where the blocksize is zero. (f_crashdisk is
6190 By default, create filesystems where the default checkinterval is 6
6191 months (180 days). Linux servers can be robust enough that 20 reboots
6192 can be a long, long time.
6194 Added configure flag --enable-old-bitops, which forces the bitops to
6195 use the old (native) bitmask operations. By default on the sparc
6196 platform, the standard ext2 bit ordering is now used.
6198 Added a new feature to e2fsck to byte-swap filesystems; this can be
6199 used to convert old m68k filesystems to use the standard byte-order
6200 storage for the superblock, inodes, and directory blocks. This
6201 function is invoked by using the '-s' option to e2fsck.
6203 Debugfs's "dump" command has been enhanced so that it writes out the
6204 exact size of the file so that the nulls at the end of the file are
6205 eliminated. The command also accept a new "-p" option which will
6206 attempt preserve to preserve the ownernship, permissions, and
6207 file modification/access times.
6209 Debugfs has two new options, -f and -R. The -R option allows the user
6210 to execute a single debugfs command from the command line. The -f
6211 option allows the user to specify a "command file" containing debugfs
6212 commands which will get executed.
6214 Dumpe2fs now pretty prints the check interval, instead of just
6215 printing the check interval as a number of seconds.
6217 Fix bugs in debugfs: the params command when no filesystem is opened
6218 no longer causes a core dump. It is now possible to unlink a file
6219 when a pathame containing a '/' is specified.
6221 Tune2fs has a new -C option which sets the number of times the
6222 filesystem has been mounted.
6224 Fix the chattr '-v' option so that it actually works. Chattr was
6225 being buggy about the -v option parsing.
6230 The directory lib/uuid contains a set of library routines to generate
6231 DCE compatible UUIDs.
6233 Extended ext2fs_namei() to handle symbolic links. Added new function
6234 ext2fs_nami_follow() which will follow last symbolic link in the case
6235 where the pathname points to a sym link.
6237 The ext2fs_block_iterate function will now return the HURD translator
6238 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6239 iterator to return data blocks only. The ext2fs.h file now defines
6240 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6241 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6242 count field of the iterator callback function.
6244 The test script driver now takes an optional second argument, which is
6245 the test case to be run. This allows you to run a test case without
6246 needing to run the entire test suite.
6248 On Linux ELF systems, install the .so files in the correct places
6249 (/usr/lib). The .so files must be stored in the same directory as the
6252 Fixed miscellaneous HURD compilation issues with header file being
6253 included in the right order.
6255 Fixed debugfs so that it resets optind to zero, not one, since setting
6256 optind to zero is more correct.
6259 E2fsprogs 1.04 (May 16, 1996)
6260 =============================
6262 First "official" (1.03 was a limited release only) to support building
6263 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6266 This package includes a RPM specs file, that it can be built using the
6267 RedHat Package Manager.
6269 E2fsck now prints a hint that if there are lots of incorrectly located
6270 inode bitmaps, block bitmaps, and inode table blocks, the user might
6271 want to try using e2fsck -b 8193 first, to see if that fares any
6274 For ext2 filesystem written with the hurd, debugfs will now print out
6275 the translator field when printing an inode structure.
6277 Lots of miscellaneous linking/installation cleanups:
6279 Libraries are now linked using a relative pathname, instead of
6280 relying on -L working correct. It doesn't, in many cases, including
6281 current versions of GNU ld. This guarantees that the build tree is
6282 linking with the right libraries, instead of the ones installed in
6285 Header files, man pages, and the et/ss shell scripts are now
6286 generated using a custom substitution script, instead of relying on
6287 the configure script. This prevents needless recompilation of
6288 files; in addition, the custom substitution script is much faster.
6290 e2fsck may now be linked dynamically, by using the
6291 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6292 since it increases e2fsck's dependence on other files, but some
6293 people need to save disk space, and other critical programs on their
6294 systems were being linked dynamically anyway.
6296 Programs such as fsck which didn't need to be linked against
6297 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6298 only link against libraries they actually need. Otherwise, those
6299 programs would require the presense of libraries that otherwise
6300 could be removed from a rescuse diskette.
6302 The ss include files are now installed correctly so they can
6303 actually be used by another package.
6305 If the profiling libraries are built, they are now installed on a
6306 "make install-libs".
6309 E2fsprogs 1.03 (March 27, 1996)
6310 ===============================
6312 Change the m68k bit numbering for bitmasks to match the bit numbering
6313 used by all other ext2 implementations. (This change was requested by
6314 the m68k kernel development team.)
6316 Support (in-development) filesystem format revision which supports
6317 (among other things) dynamically sized inodes.
6319 Fixed a bug in the ext2 library so that an intelligent error is
6320 returned if mke2fs is run with a ridiculously small number of blocks
6323 Fixed a bug in the ext2 library which required that the device be
6324 openable in read/write mode in order to determine its size. This
6325 caused e2fsck -n to require read/write access when it was not
6326 previously necessary.
6328 Fixed a bug in e2fsck which casued it to occasionally fail the test
6329 suite depending on which version of the floating point library it was
6332 Fixed a bug in e2fsck so that it now halts with a fatal error when
6333 certain superblock consistency checks fail. Previously it continued
6334 running e2fsck, with some potential confusing/damaging consequences.
6336 Added new flag to fsck which allows the root to be checked in parallel
6337 with other filesytems. This is not the safest thing in the world to
6338 do, but some system administrators really wanted it.
6340 Fixed -Wall flames in lib/ss.
6343 E2fsprogs 1.02 (January 16, 1996)
6344 =================================
6346 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6348 Change e2fsck to print statistics of how many non-contiguous files are
6349 on the system. Note that a file which is larger than 8k blocks, it is
6350 guaranteed to be non-contiguous.
6352 In mke2fs, print a warning message if a user tries to format a whole
6353 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6354 whole disk, the -F (force) option forces mke2fs to format a whole disk
6357 Fix a bug in fsck where in some cases it might start checking
6358 partitions in the next pass before it finishes checking partitions in
6359 the current pass. This still won't cause two partitions on the same
6360 disk will be checked, so it's rarely a problem in real life.
6362 Patch lsattr so that it won't hang when checking a named pipe.
6364 Minor compilation fixes:
6365 * Fix the order of libraries that were linked in debugfs.
6366 * Allow the sources to be compiled with -ansi turned on.
