1 E2fsprogs 1.42.4 (June 12, 2012)
2 ================================
4 Fixed more 64-bit block number bugs (which could end up corrupting
5 file systems!) in e2fsck, debugfs, and libext2fs.
7 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
8 not properly propagating the journal's s_errno field to the superblock
9 field; it was not checking this field if the journal had already been
10 replayed, and if the journal *was* being replayed, the "error bit"
11 wasn't getting flushed out to disk.
13 Fixed a false positive complaint by e2fsck if all of the extents in
14 the last extent tree block are uninitalized and located after the end
15 of the file as defined by i_size.
17 The dumpe2fs will now display the journal's s_errno field if it is
18 non-zero, and it will also display the journal's 64-bit feature flag
21 Fix e2fsck so that it always opens the device file in exclusive mode
22 when it might need to modify the file system, and never if the -n
23 option is specified. (Previously, there were a few corner cases where
24 it might get things wrong in either direction.)
26 E2fsck now correctly truncates or deallocates extent-mapped inodes on
27 the orphan list. The root cause was a bug in libext2fs's block
28 iterator which could end up skipping an extent when the last block in
29 an extent is removed, causing the current extent to be removed from
32 E2fsck now correctly sets the global free block and inode counts when
33 truncating or removing inodes on the orphan list in preen mode.
34 Previously, it would leave these values would be set incorrectly,
35 which is largely a cosmetic issue since the kernel no longer pays
36 attention to those fields, but it can cause spurious complaints in
37 subsequent e2fsck runs.
39 Fix i_blocks accounting when the libext2fs library needs to add or
40 remove an extent tree block on bigalloc file systems.
42 The lsattr and chattr programs now support the No_COW flag for the
45 Debugfs now interprets date strings of the form @ddd as ddd seconds
46 after the beginning of the epoch. This is handy when setting an inode
47 number into the d_time field when debugging orphan list handling.
49 Fix a precedence bug with built-in quota support which might result in
50 e2fsck paying attention to the quota inode field even if the built-in
51 quota feature flag is not set. Fortunately, in practice that
52 superblock field should be zero for non-built-in quota file systems,
53 so it's unlikely this bug would have caused problems.
55 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
61 The regression test suite can now run the integration tests in the
62 tests directory in parallel, via "make -jN check".
64 Add new test, f_zero_extent_length which tests e2fsck's handling of
65 the case where all of the extents in the last extent tree block are
66 uninitialized extents after i_size.
68 Add a new test, f_jnl_errno, which checks handling of an error
69 indication set in the journal superblock.
71 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
74 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
75 tests e2fsck's handling of orphan inodes in preen mode, and truncation
76 of extent inodes on the orphan list.
78 Fixed more OS X portability issues.
81 E2fsprogs 1.42.3 (May 14, 2012)
82 ===============================
84 Fix a bug in the Unix I/O manager which could cause corruption of file
85 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
86 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
87 dumpe2fs to incorrectly display block numbers > 32-bits.
89 Improve the support for integrated quota files (where quota is a first
90 class supported feature using hidden files in the ext4 file system).
91 Previously the quota file was getting rewritten even when it was not
92 necessary, and e2fsck would erroneously try to hide quota files which
95 Quiet complaints in e2fsck when the total free blocks or inodes are
96 incorrect in the superblock after an system crash, since we don't
97 update nor depend on the superblock summaries at each commit boundary.
99 Fixed a regression introduced in 1.42.2 which would cause applications
100 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
101 would were still using the legacy 32-bit bitmaps) to crash. This was
102 due to missing 32-bit compat code in side the function
103 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
106 Fix a bug which would cause mke2fs to fail creating the journal if
107 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
110 Updated/fixed various man pages.
112 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
115 Fixed various Debian Packaging issues.
121 Change the nonsensically wrong types in the function signature of the
122 inline function ext2fs_find_first_zero_block_bitmap2(). This was
123 caused by a cut and paste error; fortunately no code in e2fsprogs used
124 this inline function, and there are any users of this functions
125 outside of e2fsprogs.
127 Add support for systems which have valloc(), but which do have
128 posix_memalign() nor memalign() (such as MacOS 10.5).
130 Refactor and clean up the allocation of aligned buffers for Direct I/O
131 support. Previously some allocations were requesting a greater
132 alignment factor that what was strictly necessary. Also optimize
133 reading and writing bitmaps using Direct I/O when the size of the
134 bitmap did not fully cover the file system blocksize.
136 Reserve the codepoints for the INCOMPAT features LARGEDATA and
139 Improved the regression test suite by adding some new integration
140 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
141 jbd2 format, as well as f_eofblocks which tests the new handling of
142 uninitialized and initialized blocks beyond i_size. Also add a new
143 unit test which verifies 32-bit bitmaps support and the new
144 find_first_zero primitives.
146 Add a few dependencies to fix parallel (make -j) builds.
148 Removed bash'isms which were breaking the regression test suite on
149 systems where /bin/sh is not bash.
151 The config.guess and config.sub have been updated to the 2012-02-10
154 Fix a portability problem caused by assuming the present of mntent.h
155 means that setmntent() exists. Instead, explicitly test for this in
156 the configure script.
158 If the sys/signal.h header file does not exist, don't try to include
159 it, since it's not available on all systems.
161 Add support for systems that do not support getpwuid_r()
163 The configure script now supports a new option,
164 --enable-relative-symlinks, which will install relative symlinks for
165 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
167 When building BSD shared libraries make sure the LDFLAGS variable is
168 passed to the linker. Fixing this allows, for example, e2fsprogs to
169 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
172 Fix gcc -Wall nitpicks
175 E2fsprogs 1.42.2 (March 27, 2012)
176 =================================
178 The resize2fs program uses much less CPU and is much faster for very
179 large file systems. (Addresses Debian Bug: #663237)
181 The seti and freei commands in debugfs can now take an optional length
182 argument to set and clear a contiguous range of inodes.
184 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
185 plan to remove support for it from the kernel file system driver. It
186 really wasn't very useful and was causing more problems than it
187 solves. Since e2fsck will complain if inodes that should have
188 EOFBLOCKS_FL do not have the flag set, we are going to remove this
189 check from e2fsprogs first, and then only remove the flag from the
192 The mke2fs program can now use direct I/O via "mke2fs -D". This will
193 slow down the mke2fs, but it makes it more polite on a loaded server
194 by limiting the amount of memory that gets dirtied by mke2fs when it
195 is using buffered I/O.
197 E2fsck was needlessly closing and re-opening the file system as a side
198 effect of adding Multiple Mount Protection (MMP). This isn't
199 necessary for non-MMP file systems, so drop it.
201 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
202 can more easily diagnose memory allocation failures caused by
203 insufficient memory. E2fsck will now abort if there are memory
204 allocation failures when the file system is initially opened and
205 during the block group descriptor checks. (Addresses Google Bug:
208 If there are incorrect block group checks, e2fsck will now report the
209 incorrect and corrected checksum values.
211 The e2fsck progam can now write log files containing the details of
212 the problems that were found and fixed directly, via configuration
213 parameters in /etc/e2fsck.conf.
215 Added the ability to limit the number of messages reported by e2fsck
216 for a given problem type. This avoids a potential bottleneck if there
217 is a serial console which can cause a boot sequence to take a long
218 time if e2fsck needs to report many, many file system errors.
220 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
221 them to use much less memory for large file systems.
223 The dumpe2fs program will now print the expected block group checksum
224 if it is incorrect. This helps to diagnose problems caused by
225 incorrect block group checksums.
227 E2fsck now checks for extents with a zero length, since the kernel
228 will oops if it comes accross such a corrupted data structure. (See
229 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
231 E2fsck has a number of bugs relating to discard that have been fixed.
232 (1) Fixed a bug which could cause e2fsck to discard portions of the
233 inode table which were actually in use. (2) E2fsck will now avoid
234 using discard if the block device doesn't zero data on discard, since
235 otherwise this could cause problems if the file system gets corrupted
236 in the future. (3) E2fsck will now avoid using discard when it is run
237 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
238 discards in the last block group.
240 E2fsck's CPU utilization in pass 5 has been optimized, which will
241 speed up e2fsck slightly.
243 E2image will now skip copying uninitialized bitmap and inode table
246 Fixed mke2fs -S so it does not corrupt the first block group's
249 E2fsck will now check the new sysfs interface to determine if we are
250 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
252 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
254 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
259 Fixed various portability issues for non-Linux systems, particularly
260 MacOS X, as well as Linux systems running with the just-released glibc
263 Fix file descriptor leak in ext2fs_close() if the file system with
264 uninit_bg is opened read/only with a backup superblock. (Addresses
265 SourceForge Bug: #3444351)
267 Fixed an invalid return in a non-void function in the quota code.
268 (Addresses SourceForge Bug: #3468423)
270 Fixed the debian rules file so that the calls to dpkg-buildflags works
271 when the shell is dash.
273 The debian package build now uses V=1 so that there is more
274 information about potential build failures in debian buildd logs.
276 If the uninit flags get cleared by functions such as
277 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
278 superblock is marked dirty and the block group descriptor checksum is
279 updated if necessary.
281 The debian rules file will now try to load debian/rules.custom of it
282 exists. This flie can skip various builds for speed reasons if there
283 is no need for the e2fsck-static or udeb packages. Available
284 customizations in the rules file includes SKIP_STATIC=yes,
285 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
287 In addition, if the file misc/mke2fs.conf.custom.in exists in the
288 source tree, it will be used instead of the standard misc.conf file in
289 the upstream sources. This makes it easier for Debian-derived systems
290 to distribute a custom mke2fs.conf file without having to worry about
291 merge issues if future versions of e2fsprogs makes changes in the
292 upstream default version of mke2fs.conf.
295 E2fsprogs 1.42.1 (February 17, 2012)
296 ===================================
298 The mke2fs and e2fsck now use significantly less memory when creating
299 or checking very large file systems. This was enabled by adding
300 extent-based bitmaps which are stored using a red-block tree, since
301 block and inode allocations tend to be contiguous.
303 The command mke2fs -S is used as a last ditch recovery command to
304 write new superblock and block group descriptors, but _not_ to destroy
305 the inode table in hopes of recovering from a badly corrupted file
306 system. So if the uninit_bg feature is enabled, mke2fs -S will now
307 set the unused inodes count field to zero. Otherwise, e2fsck -fy
308 after using mke2fs -S would leave the file system completely empty.
310 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
311 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
312 installed an mke2fs binary using that name.
314 The usage and help messages for the -G, -t and -T options in mke2fs
317 If e2fsck needs to use the backup group descriptors, the
318 ext2fs_open2() function clears the UNINIT bits to ensure all of the
319 inodes in the file systems get scanned. However, the code which reset
320 the UNINIT flags did not also recalculate the checksum, which produced
321 many spurious (and scary) e2fsck messages. This has been fixed by
322 resetting cheksums when the UNINIT bits are cleared.
324 Relax a check in e2fsck which required that the block bitmap to be
325 initialized when the inode bitmap is in use. This will allow us to
326 eventually eliminate code from the kernel which forcibly initialized
327 the block bitmap when the inode bitmap is first used, requiring an
328 extra journal credit and disk write. (Addresses Google Bug: #5944440)
330 Make sure rdebugfs (which may be installed setuid or setgid disk) does
331 not honor environment variables if euid != uid or egid != gid.
333 Debugfs's ncheck command has been optimized and now is much more
334 robust with faced with corrupted file systems. The ncheck command
335 also now has a -c option which will verify the file type information
336 in the directory entry to see if matches the inode's mode bits. This
337 is extremely useful when trying to use debugsfs to determine which
338 parts of the file system metadata can be trusted.
340 E2image will try to use ftruncate64() to set the i_size for raw
341 images, instead of writing a single null byte. This avoid allocating
342 an extra block to the raw image, for those file systems and/or
343 operating systems that support this. (Linux does.) In addition, fix
344 a logic bug that caused the file to not be properly extended if the
345 size of the last hole was exactly an multiple of a megabyte.
347 Fixed a bug in resize2fs where for 1k and 2k file systems, where
348 s_first_data_block is non-zero, this wasn't taken into account when
349 calculate the minimum file system size for use with the -M option.
351 Fixed the badblocks program to honor the -s flag when in read-only -t
352 mode. (Addresses Debian Bug #646629)
354 Update Czech, Dutch, French, Polish, and Sweedish translation from the
357 Fixed various Debian Packaging issues so that dpkg-buildflags is used
358 if present, which allows e2fsprogs to be built with security hardening
359 flags. (Addresses Debian Bugs: #654457)
364 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
365 This was only an issue for programs compiled against e2fsprogs 1.41
366 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
369 The libext2fs library now uses sysconf() to fetch the page size, instead
370 of the deprecated getpagesize().
372 The ext2fs_get_pathname() function will return a partial path if an a
373 directory in the path is not a directory, displaying it as an inode
374 number in angle brackets instead of giving up and displaying an error.
375 This is much more helpful when a user is trying to debug a corrupted
378 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
380 Added a new library function, ext2fs_file_get_inode_num(), for use by
383 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
384 file, it actually works.
386 The block iterator now properly honors the BLOCK_ABORT flag for
387 extent-based flags. Previously, it didn't, which generally made code
388 be less efficient, but it could cause bugs in ext2fs_link(), for
389 example, by causing it to insert multiple directory entries.
391 Fixed an (harmless other than causing a compiler warning) use of an
392 uninitialized variable in e2fsck's MMP code.
395 E2fsprogs 1.42 (November 29, 2011)
396 ==================================
398 This release of e2fsprogs has support for file systems > 16TB. Online
399 resize requires kernel support which will hopefully be in Linux
400 version 3.2. Offline support is not yet available for > 16TB file
401 systems, but will be coming.
403 This release of e2fsprogs has support for clustered allocation. This
404 reduces the number of block (now cluster) bitmaps by allocating and
405 deallocating space in contiguous power-of-2 collections of blocks,
406 which are called clustered. This is a file system level feature,
407 called 'bigalloc', which must be enabled when the file system is
408 initially formatted. It is not backwards compatible with older
411 Added support for the Multi-Mount Protection (MMP) feature.
413 E2fsck more efficiently uses scratch files for really big file
414 systems. (This is a feature that has to be turned on explicitly; see
415 [scratch_files] in the e2fsck.conf man page.)
417 Fix a bug in e2fsck where if the free blocks and inodes counts are
418 incorrect, e2fsck would fix them without printing an error message.
419 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
420 any explanation of what was fixed.
422 E2fsck will no longer attempt to clone an extended attribute block in
423 pass1b handling if the file system does not support extended
426 E2fsck will be more careful accidentally asking the user to continue
427 if the file system is mounted, so that an escape sequence won't cause
428 a false positive. (Addresses Debian Bug: #619859)
430 E2fsck now uses less cpu time in pass 5 when large portions of the
431 bitmaps are uninitialized.
433 E2fsck will no longer segault when a corrupted file system has a bad
434 extent, and removing it leads to a block needing to be deallocated.
435 (Addresses SourceForge Bug: #2971800)
437 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
438 and print debugging information to make it easier to find potential
441 E2fsck will check to see if the bad block inode looks insane, and will
442 skip trying to use if it certain fields which should be zero look
443 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
444 to get confused and do more harm than good.
446 If e2fsck modifies certain superblock fields which the kernel doesn't
447 look at, it will now mark the superblock as dirty without marking the
448 file system as changed. This avoids signalling the init scripts that
449 a reboot is necessary, since the kernel isn't going to look at those
450 fields, so it won't care if they have been changed.
452 Fixed a bug in the libext2fs library (in the binary search routine of
453 the icount abstraction) that could (very, very rarely) cause e2fsck to
454 die in the middle of pass 1 or pass 2 processing.
456 E2fsck will not try to do a discard operation if the -n option was
457 specified on the command line.
459 E2fsck now supports an extended "discard" option which will cause
460 e2fsck to attempt discard all unused blocks after a full, successful
463 E2fsck will check for the bad block inode to make sure it looks sane
464 before trusting it, to avoid causing more harm than good to the file
467 E2fsck now returns additional status bits in its exit code if it
468 aborts early in the e2fsck run.
470 E2fsck now correctly calculates the maximum file size in the case of
471 the huge_file file system feature enabled without extents.
473 The mke2fs and e2fsck programs now tries to use the punch hole command
474 as a "discard" when operating on normal files.
476 The e2image program now supports the qcow2 format, which is a more
477 efficient way of capturing file system dumps.
479 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
480 per-device defaults to be specified in the configuration file.
482 Mke2fs now supports the reserved_ratio relation in the [defaults] and
483 [fs_types] section in mke2fs.conf.
485 Mke2fs now creates extent-mapped directories for the root and
486 lost+found directories.
488 Mke2fs will skip zero'ing the journal if the extended option
489 "lazy_journal_init" is specified. This can save a lot of time, but it
490 does add a small amount of risk if the system crashes before the
491 journal is overwritten entirely once. It is epsecially useful for
494 Mke2fs will now create file systems that enable user namespace
495 extended attributes and with time- and mount count-based file
496 system checks disabled.
498 Mke2fs will not set a stride or strip size of one block based on block
499 device attributes obtained from sysfs.
501 Mke2fs now displays a progress report during the discard process.
503 Mke2fs now handles extreme file system parameters correctly which
504 previously caused the inodes per group to drop below 8, leading to a
505 segfault. (The inodes per group must be a multiple of 8, but the code
506 didn't correctly deal with an inodes per group count less than 8.)
508 Mke2fs and tune2fs previously would give an error if the user tried
509 setting the stride and stripe-width parameters to zero; but this is
510 necessary to disable the stride and stripe-width settings. So allow
511 setting these superblock fields to zero. (Addresses Google Bug:
514 Mke2fs now gives a warning if the auto-detected block size exceeds the
517 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
518 is the default), mke2fs will now set the s_max_mnt_count superblock
519 field to -1, instead of 0. Kernels older then 3.0 will print a
520 spurious message on each mount then they see a s_max_mnt_count set to
521 0, which will annoy users. (Addresses Debian Bug: #632637)
523 The default mke2fs.conf now has entries for "big" and "huge", which
524 are needed for very big file systems.
526 The resize2fs program now has support for a new online resize ioctl
527 that can support file systems > 16TB, once it arrives in v3.x kernels.
529 Fixed bug which caused resize2fs to fail when shrinking an empty file
530 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
532 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
534 Allow tune2fs to remove external journals if the device can not be
537 Debugfs's icheck will now correctly find inodes which use the
538 searched-for block as an extended attribute block.
540 Debugfs now has a new "punch" command which remove blocks from the
543 Debugfs now has a new "e2freefrag" command which analyzes the free
544 space fragmentation of the file system, using the same code as the
547 Debugfs now has a "filefrag" command which displays information about
548 a file's fragmentation.
550 Add support to build a metadata-only, read-only, stripped-down version
551 of debugfs called rdebugfs.
553 Fixed a potential stack overrun bug in debugfs.
555 The badblocks program now correctly recovers from I/O errors when
556 direct I/O is being used. The badblocks command now also supports a
557 -B option which forces the use of buffered I/O, and the -v option will
558 provide a more detailed breakdown of read, write, and failed
561 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
563 Added support for journals larger than 2GB.
565 Support using both hard links and symlinks when installing e2fsprogs.
567 Add overflow checking to tune2fs -i's fsck interval, which must fit in
570 The debugfs command now has a new 'blocks' command which prints out
571 data blocks of a particular inode in a format which is useful for
574 Filefrag will report 0 extents correctly in verbose mode. (Addresses
575 RedHat Bugzilla: #653234)
577 Filefrag has been fixed so its -v report prints the correct expected
578 block number (previously there had been an off-by-one error). In
579 addition, it will now display the number of contiguous extents when -v
580 is not specified. This makes it consistent with the number of extents
581 printed when the -v option was specified. In addition, the number of
582 contiguous extents is far more interesting/useful than the number of
583 physical extents for very large files. (Addresses Debian Bug:
586 Logsave's usage message has been fixed. (Addresses Debian Bug:
589 Avoid an infinite loop in ext2fs_find_block_device() if there are
590 symlink loops in /dev caused by a buggy udev.
592 Added a useful "fallocate" program to the contrib directory.
594 Fixed an ABI compatibility problem in libext2fs which broke the dump
595 program. Also added back some macros which dump needed so it could

620 Initial support for quota as an integrated feature, where the quota
621 files are hidden system files that are automatically maintained by
622 e2fsck is present, although disabled by default. It must be enabled
623 by using the configure option --enable-quota.
625 Reserved the on-disk fields for the metadata checksum and snapshot
626 features, which are currently in development.
628 The ext2fs library now has the new functions ext2fs_punch(),
629 ext2fs_get_memzero() and ext2fs_file_get_inode().
631 The ext2fs library now has support for calculating the crc32c checksum
632 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
634 The I/O manager now supports the discard operation.
636 Reserved file system code points for new 1st class quota feature.
638 Shortened the compilation lines by moving the autoconf defines to
639 a config.h header file.
641 Fixed a potential free of an unitialized pointer in
642 ext2fs_update_bb_inode().
644 Fixed miscellaneous gcc -Wall and coverity warnings.
646 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
648 Fixed a build failure when OMIT_COM_ERR is defined.
650 Improved error checking and fixed memory leaks caused by error return
653 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
654 the fsync() to be skipped.
656 Added a test for extent-mapped journals by mke2fs and tune2fs.
658 Added a test for creating a large (over 4GB) journal using mke2fs.
660 Added a test to make sure the inode size remains constant.
662 The regression test script now prints the list of which tests failed.
664 The regression test system now uses /tmp for its scratch files, which
665 is often a tmpfs mounted file system and hence much faster.
667 The i_e2image test was fixed so it works with valgrind.
669 Tests that rely on debugfs are now skipped if debugfs wasn't built.
671 Fixed the dependencies for "make check" so all required dependencies
672 are built before running the gression tests.
674 A link to com_err.h is installed in $(includedir) during a "make install".
676 The po/*.gmo files are automatically rebuilt if they are missing or
677 out of date. This helps out Debian packaging.
679 Allow ext2fs_get_memalign() to compile on systems that don't have
682 Fixed a namespace leak in libext2fs (tdb_null).
685 E2fsprogs 1.41.14 (December 22, 2010)
686 =====================================
688 Fix spurious complaint in mke2fs where it would complain if the file
689 system type "default" is not defined in mke2fs.conf.
691 The resize2fs program will no longer clear the resize_inode feature
692 when the number reserved group descriptor blocks reaches zero. This
693 allows for subsequent shrinks of the file system to work cleanly for
694 flex_bg file systems.
696 The resize2fs program now handles devices which are exactly 16T;
697 previously it would give an error saying that the file system was too
700 E2fsck (and the libext2fs library) will not use the extended rec_len
701 encoding for file systems whose block size is less than 64k, for
702 consistency with the kernel.
707 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
708 been fixed. (Addresses Sourceforge Bug: #3138115)
710 The ext2fs_block_iterator2() function passed an incorrect ref_offset
711 to its callback function in the case of sparse files. (Addresses
712 Sourceforge Bug: #3081087)
714 Fix some type-punning warnings generated by newer versions of gcc.
717 E2fsprogs 1.41.13 (December 13, 2010)
718 =====================================
720 E2fsck now supports the extended option "-E journal_only", which
721 causes it to only do a journal replay. This is useful for scripts
722 that want to first replay the journal and then check to see if it
725 E2fsck will now support UUID= and LABEL= specifiers for the -j option
726 (which specifies where to find the external journal). (Addresses
729 E2fsck now has support for the problems/<problem code>/force_no
730 configuration option in e2fsck.conf, which forces a problem to not be
733 Dumpe2fs will now avoid printing large negative offsets for the bitmap
734 blocks and instead print a message which is a bit more helpful for
735 flex_bg file systems.
737 Mke2fs will now check the file system type (specified with the -t
738 option) to make sure it is defined in the mke2fs.conf file; if it is
739 not, it will print an error and abort. If the usage type (specified
740 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
741 warning but will continue. (Addresses Debian Bug #594609)
743 Clarified error message from resize2fs clarifying that on-line
744 shrinking is not supported at all. (Addresses Debian Bug #599786)
746 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
747 displayed. (Addresses Debian Bug #555456)
749 E2fsck will open the external journal in exclusive mode, to prevent
750 the journal from getting truncated while it is in use due to a user
751 accidentally trying to run e2fsck on a snapshotted file system volume.
752 (Addresses Debian Bug #587531)
754 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
757 The tune2fs program can now set the uninit_bg feature without
760 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
761 default mount options settings which were added in 2.6.35.
763 The e2fsck and dumpe2fs programs now support the new ext4 superblock
764 fields which track where and when the first and most recent file
765 system errors occurred. These fields are displayed by dumpe2fs and
766 cleared by e2fsck. These new superblock fields were added in 2.6.36.
768 Debugfs now uses a more concicse format for listing extents in its
769 stat command. This format also includes the interior extent tree
770 blocks, which previously was missing from stat's output for
773 Debugfs has a new option, -D, which will request Direct I/O access of
776 Mke2fs will skip initializing the inode table if a device supports
777 discard and the discard operation will result in zero'ed blocks.
779 Badblocks will now correctly backspace over UTF-8 characters when
780 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
781 Debian Bugs #583782 and #587834)
783 E2freefrag will now display the total number of free extents.
785 Resize2fs -P no longer requires a freshly checked filesystem before
786 printing the minimum resize size.
788 Fixed a floating point precision error in a binary tree search routine
789 that can lead to seg fault in e2fsck and resize2fs.
791 Fixed a bug in e2fsck where if both the original and backup superblock
792 are invalid in some way, e2fsck will fail going back to the original
793 superblock because it didn't close the backup superblock first, and
794 the exclusive open prevented the file system from being reopened.
796 Fixed a big in e2freefrag which caused getopt parsing to fail on
797 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
799 Clarified an mke2fs error message so a missed common in an -E option
800 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
801 results in a more understandable explanation to the user.
803 Mke2fs now displays the correct valid inode ratio range when
804 complaining about an invalid inode ratio specified by the user.
806 Mke2fs now understands the extended option "discard" and "nodiscard",
807 and the older option -K is deprecated. The default of whether
808 discards are enabled by default can be controled by the mke2fs.conf
811 Mke2fs's handling of logical and physical sector sizes has been
812 improved to reflect the fact that there will be some SSD's with 8k and
813 16k physical sectors arriving soon. Mke2fs will no longer force block
814 size to be the physical sector size, since there will be devices where
815 the physical sector size is larger than the system's page size, and
816 hence larger than the maximal supported block size. In addition, if
817 the minimal and optimal io size are not exported by the device, and
818 the physical sector size is larger than the block size, the physical
819 sector size will be used to set the Raid I/O optimization hints in the
822 E2fsck will now display a better, more specific error message when the
823 user enters a typo'ed device name, instead of blathering on about
824 alternate superblocks.
826 Fixed various Debian Packaging Issues
828 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
829 #589345, #591083; Addresses Launchpad Bug: #505719)
831 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
832 Polish, Swedish, and Vietnamese translations.
838 Fix a dependency definition for the static and profiled blkid
839 libraries which could cause compile failures in some configurations.
840 (Addresses Debian Bug: #604629)
842 Add support for Direct I/O in the Unix I/O access layer.
844 Fixed a memory leak in the Unix I/O layer when changing block sizes.
846 Fixed minor memory leaks in mke2fs.
848 Added a new function to the ext2fs library, ext2fs_get_memalign().
850 The tst_super_size test program will check to make sure the superblock
851 fields are correctly aligned and will print them out so they can be
852 manually checked for correctness.
854 Fixed some makefile dependencies for test programs in lib/ext2fs.
856 Reserved the feature flags and superblock fields needed for the Next3
859 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
860 EXT4_INCOMPAT_EA_INODE.
863 E2fsprogs 1.41.12 (May 17, 2010)
864 ================================
866 Mke2fs now gives a correct error message if the external journal
867 device is not found. (Addresses Red Hat Bug #572935)
869 Resize2fs -P will now refuse to print a minimum size if the file
870 system is not clean. Previously it would go ahead and print a minimum
871 size anyway, which might not be correct, leading to user confusion.
873 E2fsck now tests for extents that begin at physical block 0 and
874 rejects them as invalid. (Addresses Google Bug: #2573806)
876 Fixed a bug in e2fsck which could cause it to crash when trying to
877 remove an invalid extent and the block bitmaps hadn't yet been loaded.
878 (Addresses SourceForge Bug: #2971800)
880 E2fsck now will completely skip time-based checks if the system clock
881 looks insane or the option broken_system_clock is set in
884 E2fsck would previously report an i_blocks corruption for a 4T file
885 created using posix_fallocate; this bug has been fixed.
887 E2fsck will now correctly mark a sparse journal as invalid and will
888 delete and recreate the journal to address the problem.
890 E2fsck would previously incorrectly ask the user whether she would
891 like to abort the file system check after finding a problem --- and
892 then abort regardless of the user's answer. This is annoying, and
895 E2fsck can now continue even if it fails to recreate the resize
896 inode; previously it would just abort the file system check
899 E2fsck could potentially remove directory entries for inodes found in
900 the unused region of the inode table; this would generally happen on
901 ext4 file systems that do not use journaling. This bug has been fixed
902 by not clearing these directory entries once it has been established
903 that bg_unused_inodes may not be trustworthy; once pass #2 has been
904 completed, e2fsck will restart the file system check from the
905 beginning, and then it will be safe to delete any directory entries
906 pointing to inodes that appear to be deleted. (Addresses Google Bug:
909 E2fsck will not try to set the block group checksums if the user
910 cancels the fsck with a control-C. It's a bad idea to set the
911 checksums if e2fsck hasn't been completed, and it often results an the
912 error message, "Inode bitmap not loaded while setting block group
913 checksum info". (Addresses Launchpad Bug: #582035)
915 The mke2fs program now queries the kernel for the physical as well as
916 the logical sector size, and will not allow a blocksize below the
917 logical, and will strongly encourage a blocksize at least as big as
918 the physical blocksize. This is needed for 4k sector drives that
919 emulate 512 byte sector sizes.
921 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
922 rarely needed, but it is a legal value.
924 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
925 not needed, and offer to clear it; this is a sign of a kernel bug, but
926 more importantly, some released kernels may crash when this situation
927 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
929 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
930 i_size is correct. (Kernels starting with 2.6.34 will set
933 The com_err library will now only output ^M (a CR character) when the
936 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
937 and Vietnamese translations.
939 Fixed various Debian packaging issues --- see debian/changelog for
940 details. (Addresses Debian Bugs: #571247, #563487)
946 The regression test suite now uses its own mke2fs.conf file, so that
947 downstream distributions want change the mke2fs.conf file which is
948 distributed in the RPM or dpkg file, without worrying about screwing
949 up the regression test results.
951 Always build namei.o so that building with configure --disable-debugfs
952 works correctly. Long-term, if we care about reduced e2fsprogs
953 builds, we need a more general solution for deciding what .o files are
954 needed for a particular build. Given that install floppies are going
955 (gone?) the way the dodo bird, we probably don't care, though.
956 (Addresses Sourceforge Bug: #2911433)
958 Add configure options --enable-symlink-build and
959 --enable-symlink-install, which allow e2fsprogs be built using
960 symlinks instad of hard links, and to be installed using symlinks
961 instead of hard links, respectively. It is useful when the file
962 system where the build is taking place, or the file system where
963 e2fsprogs is installed, can't handle hard links for some reason.
964 (Addresses Sourceforge Bug: #1436294)
966 Fixed compile warning in mke2fs.c.
969 E2fsprogs 1.41.11 (March 14, 2010)
970 ==================================
972 E2fsck will no longer give a fatal error and abort if the physical
973 device has been resized beyond 2**32 blocks. (Addresses Launchpad
976 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
977 the allocation status of the block <blk>. (Addresses Debian Bug:
980 E2fsck now prints a much more emphatic and hopefully scary message
981 when a file system is detected as mounted while doing a read/write
982 check of the filesystem. Hopefully this will dissuade users from
983 thinking, "surely that message doesn't apply to *me*" :-(
985 E2fsck -n will now always open the file system read-only. We now
986 disallow certain combination of options which previously were manual
987 exceptions; this is bad because it causes users to think they are
988 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
989 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
991 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
992 it detected a badly aligned partition. Unfortunately, this broke some
993 distribution installation scripts, so it now just prints the warning
994 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
995 Launchpad Bug: #530071)
997 Mke2fs would take a long time to create very large journal files for
998 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
1001 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
1002 2.6.34 kernels to make e2fsck not complain about blocks deliberately
1003 fallocated() beyond an inode's i_size.
1005 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1006 e2fsck -fD can corrupt non-indexed directories when are exists one or
1007 more file names which alphabetically sort before ".". This can happen
1008 with ext2 filesystems or for small directories (take less than a lock)
1009 which contain filenames that begin with a space or some other
1010 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
1017 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

1030 Add libss support for libreadline.so.6.
1032 Fix e2fsck's check for extent-mapped directory with an incorrect file
1035 Add new e2fsck.conf configuration option, default/broken_system_clock
1036 to support systems with broken CMOS hardware clocks. Also, since too
1037 many distributions seem to have broken virtualization scripts now,
1038 e2fsck will by default accept dates which are off by up to 24 hours by
1039 default. (Addresses Debian Bugs: #559776, #557636)

1046 of fixing file system problems. This reduces the number of spurious
1047 differences found in pass #5.

1053 sparse directories which use extents).
1055 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
1057 Fix a bug in filefrag where on platforms which can allow file systems
1058 with 8k blocks, that it doesn't core dump when it sees a file system
1059 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
1062 E2fsck will correctly fix directories that are have an inaccurate
1063 i_size as well as other problems in a single pass, instead of

1098 Fix e2fsck's handling of 64-bit i_blocks fields.
1100 E2fsck will now print "Illegal indirect block", "Illegal

1102 "Illegal block #-2", etc. This makes it easier for users to
1103 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)

1160 E2fsprogs 1.41.9 (August 22, 2009)
1161 ==================================
1163 Fix a bug in e2fsck routines for reallocating an inode table which
1164 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1165 filesystem feature with a relatively rare (and specific) filesystem
1166 corruption. This fix causes e2fsck to try to find space for a new
1167 portion of the inode table in the containing flex_bg, and if that
1168 fails, the new portion of the inode table will be allocated in any
1169 free space available in the filesystem.
1171 Make e2fsck less annoying by only asking for permission to relocate a
1172 block group's inode table once, instead of for every overlapping
1173 block. Similarly, only ask once to recompute the block group
1174 checksums, instead of once for each corrupted block group's checksum.
1176 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1177 not present, and it needs to fall back to using the FIBMAP ioctl.
1179 Fix filefrag to correctly print the number of extents for zero-length
1180 files. (Addresses Debian Bug: #540376)
1182 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1183 to more easily debug the FIBMAP code.
1185 Fixed filefrag for non-extent based files.
1187 Add a new program, e2freefrag, which displays information about the
1188 free space fragmentation in an ext2/3/4 filesystem.
1190 Fix inode resizing via tune2fs -I so that it works correctly in the
1191 face of non-empty bad blocks inodes, and if the filesystem was
1192 formatted using the "mke2fs -E stride=N" option for RAID arrays.
1194 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1195 and corrupt large directories if the directory needs to shrink by more
1196 than one block. (Addresses Debian Bug: #537510)
1198 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1199 last mount times are in the future, they are corrected even if
1200 buggy_init_scripts is set. This is needed because otherwise resize2fs
1201 will refuse to resize the filesystem, even after running "e2fsck -f".
1202 (Addresses Launchpad bug: #373409)
1204 E2fsck will now print much fuller information when the last mount time
1205 or last written time is in the future, since most people can't seem to
1206 believe their distribution has buggy init scripts, or they have a
1207 failed CMOS/RTS clock battery.
1209 Enhance dumpe2fs to dump the extent information via the 'stat'
1210 command, and more detailed extent information via the new command

1214 Translation Project.
1216 Fixed various Debian packaging issues --- see debian/changelog for
1222 Fixed miscellaneous gcc -Wall warnings.
1224 Fixed memory leak in error path in ext2fs_block_iterate2()
1226 Fixed non-Linux build of the intl directory by adding support for the
1229 The bitmap read/write functions now treat uninitialized bitmaps as
1230 unallocated; this fixes a number of problems in all e2fsprogs for ext4
1231 filesystems when there is a need to allocate new blocks or inodes, and
1232 there aren't any free blocks or inodes in the already-used block
1235 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
1236 get inserted into the extent tree when they are not needed.
1239 E2fsprogs 1.41.8 (July 11, 2009)
1240 ================================
1242 Fix resize2fs's online resizing, fixing a regression which in
1243 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
1245 Fix potential filesystem corruptions caused by using resize2fs to
1246 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
1249 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
1250 setgid and the currently running program doesn't have write access to
1251 the uuidd work directory.
1253 Add safety checks (for non-Linux systems) so that uuidd isn't run with
1254 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1255 will be careful not to close the file descriptor for its unix domain
1256 socket when it detaches itself from the controlling tty. Also add
1257 safety checks so that if the unix domain socket between the uuid
1258 library and uuidd program is closed for any reason, both the library
1259 and the uuidd will return an appropriate error code instead of looping
1260 in an infinite loop.
1262 The e2croncheck script, which creates an LVM snapshot and then checks
1263 the ext3/4 filesystem via the LVM snapshot, has been added to the
1266 Fix filefrag program for files that have more than 144 extents.
1268 Update French, Polish, Czech, Indonsian, and Sweedish translation from
1269 the Translation Project.
1271 Fixed various Debian packaging issues --- see debian/changelog for
1272 details. (Addresses Debian Bug #535530)
1274 Update/clarify man pages.
1279 Fix compilation problem when configured with --disable-uuid.
1281 Don't build uuidgen if configured with --disable-uuid.
1283 Add the new library function ext2fs_test_inode_bitmap_range(), and
1284 optimized ext2fs_test_block_bitmap_range(), which will be needed for
1285 future optimizations for e2fsck.
1287 Fix makefile dependencies for libcom_err so that the Makefiles work
1288 well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
1290 Enhance the build system so that the full set of commands executed by
1291 the Makefiles are displayed, instead of the Linux kernel summary
1292 output, if the build was configured with --enable-verbose-makecmds, or
1293 if GNU make is in use and the V variable is non-null, i.e., via "make
1297 E2fsprogs 1.41.7 (June 29, 2009)
1298 ================================
1300 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
1301 uninitalized data into the portion of the inode beyond the first 128
1302 bytes when operating on inodes mapped via extents; potentially
1303 corrupting filesystems.
1305 Fix memory leaks in e2fsprogs, including a very large memory leak
1306 which can cause e2fsck to run out of memory when checking very large
1307 filesystems using extents.
1309 The logsave program will now filter out the ^A and ^B characters when
1310 writing to the console.
1312 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
1313 end of the block even if the directory block is corrupted.
1315 Fix debugfs from core dumping if the logdump command fails to open the
1318 Enhance badblocks to print the currently tested block number when
1319 interrupted with ^C.
1321 Fix lsattr to exit with a non-zero status when it encounters errors.
1322 (Addresses RedHat Bugzilla #489841)
1324 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
1325 filesystems as the kernel when encoding rec_len >= 64k. For 64k
1326 filesystems (currently all that is supported by e2fsprogs, this is
1327 only a minor corner case).
1329 Resize2fs will now update the journal backup fileds in the sup0erblock
1330 if the journal is moved; this avoids an unnecessary full fsck after
1331 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
1333 Fix libext2fs to properly initialize i_extra_size when creating the
1334 journal and resize inodes.
1336 Change badblocks to allow block sizes larger than 4k.
1338 Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
1340 Update Chinese and Czech translation from the Translation Project.
1342 Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
1348 Add --disable-libuuid option to configure which uses an in-system
1349 installed version of libuuid; the private version is enabled by
1352 Add --valgrind-leakcheck option to the test_script program which runs
1353 valgrind with the appropriate options to find memory leaks.
1356 E2fsprogs 1.41.6 (May 30, 2009)
1357 ===============================
1359 Fix a critical regression in e2fsck introduced version 1.41.5 which
1360 can undo updates to the block group descriptors after a journal replay.
1362 If e2fsck receives an I/O error while replaying the journal, prompt
1363 the user whether they want to ignore the error or not; if e2fsck is
1364 run in preen mode, force fsck to abort the preen pass.
1366 Fix a bug which would cause e2fsck to core dump if the filesystem
1367 contains a corrupt extent header, and the user declines to clear the
1368 inode. (Addresses Sourceforge Bug: #2791794)
1370 Fix e2fsck to restart only once in the case of multiple block groups
1371 which inodes in use that are in the uninitialized part of the block
1372 group's inode table.
1374 To reduce user confusion, if the /etc/mtab file is missing
1375 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1376 new, explicit error code to indicate this case. This will cause
1377 e2fsck to give a clearer error message when the user is using buggy
1378 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
1381 Fix e2fsck so that if the primary group descriptors are corrupted, but
1382 the backup superblock is entirely invalid, to go back to using (and
1383 fixing) the priary group descriptors instead of completely giving up
1384 on the filesystem. (Addresses Debian Bug: #516820)
1386 Change e2fsck to not abort a preen pass if an inode is found to have
1387 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
1388 kernels (post 2.6.29) will ignore this field. So let's fix it
1389 automatically during the preen pass instead of forcing the user to fix
1390 this up manually. (Addresses Debian Bug: #526524)
1392 Add resource tracking for e2fsck passes 1b through 1d.
1394 Speed up e2fsck by eliminating unnecessary journal checks if the
1395 filesystem is already mounted and doesn't need recovery (since the
1396 kernel would have run the journal when the filesystem was mounted.)
1397 Also speed up e2fsck by avoiding unnecessary block group descriptor
1398 updates in ext2fs_close().
1400 Add support to chattr to migrate inodes from using direct/indirect
1403 Avoid corrupting the filesystem if there is an attempt to shrink a
1404 filesystem using resize2fs smaller than posible by making
1405 ext2fs_set_bmap() more careful not to delete the old block until the
1406 new block can be inserted. In addition, fix a bug in how the minimum
1407 size of the filesystem (plus a safety margin) is calculated, and
1408 modify resize2fs to refuse to shrink the filesystem below that minimum
1409 size without the force flag.
1411 Teach blkid to try to figure out DM device names using take advantage
1412 of information in sysfs when running on kernels (2.6.29 and later)
1413 which provide this information in /sys/block/dm-<N>/dm/name; this is
1414 much faster than scanning for the devncie number in /dev/mapper.
1416 Fix blkid to prefer /dev/mapper/<name> device names instad of the
1417 private /dev/dm-X names.
1419 Add an -a option to debugfs's close_filesys command which writes any
1420 changes to the superblock or block group descriptors to all of the
1421 backup superblock locations.
1423 Add support to the filefrag program to use the FIEMAP ioctl.
1425 Update Chinese translation from the Translation Project.
1427 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
1428 Launchpad Bug: #381854)
1430 Fixed various Debian packaging issues --- see debian/changelog for
1431 details. (Addresses Debian Bug #506064)
1437 Add test code to make sure e2fsck's problem.c doesn't have two problem
1438 codes assigned to duplicate values.
1440 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1441 (Addresses Sourceforge Bug: #2780205)
1443 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1444 function declaration for init_resource_track() and
1445 print_resource_track() when RESOURCE_TRACK is not defined.
1447 The test code which is used to build the tst_csum progam has been
1448 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1449 avoid compile problems caused by not having a prototype for
1450 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
1452 Update the config.guess and config.sub file to the latest from the
1453 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
1454 Debian Bug: #528330)
1456 Add a new function, ext2fs_extent_open2(), which behaves like
1457 pext2fs_extent_open(), but uses the user-supplied inode structure
1458 when opening an extent instead of reading the inode from disk.
1461 E2fsprogs 1.41.5 (April 23, 2009)
1462 =================================
1464 Fix a number of filesystem corruption bugs in resize2fs when growing
1465 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1468 Debugfs can now set i_file_acl_high via the set_inodes_field command,
1469 and print a 64-bit file acl. This is useful for debugging filesystem
1470 corruptions where the high bits of i_file_acl_high are set. E2fsck
1471 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1472 since some Linux kernel versions pay attention to this field even when
1475 Speed up e2fsck when checking clean filesystems by avoiding
1476 unnecessary block reads, and coalescing the block group descriptor
1477 blocks so they are read using a single read operation.
1479 The libuuid library will now close all file descriptors before running
1480 uuidd. This avoids problems when the calling program has open sockets
1481 which then never get closed because uuidd is a long-running helper
1482 daeomn. (Addresses Launchpad bug: #305057)
1484 In order to avoid unnecessary full filesystem checks by e2fsck after
1485 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1486 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
1488 Mke2fs will avoid trying to create the journal when run in
1489 superblock-only mode (mke2fs -S), since the left-over journal in the
1490 inode table will cause mke2fs to fail.
1492 Fix a bug in libext2fs functions that check to see if a particular
1493 device or filesystem image is mounted, which would cause these
1494 functions to report that a file identical to the (relative) pathname
1495 used by a pseudo-filesystem was mounted when in fact it was not.
1497 Update Czech translation from the Translation Project.
1499 Add Chinese (simplified) translation from the Translation Project.
1501 Fix support for external journals (which was broken in e2fsprogs
1504 Fix a regression in debugfs where the "stat" command when no
1505 filesystem was open would cause debugfs to crash with a segmentation
1508 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1509 used to support filesystems without a journal. Update the blkid
1510 library so it understands this.
1512 The blkid library will remove an entry from the blkid cache
1513 representing the entire disk if partitions are found, since presuambly
1514 the device previously had no partition table, but has now transitioned
1515 to using a partition table.
1517 Add a check to mke2fs and tune2fs that the argument to the -m option
1518 (which specifies the reserved ratio) must be greater than zero.
1519 (Addresses Debian Bug: #517015)
1521 Add support for tracking the number kilobytes written to the
1522 filesystem via the superblock field s_kbytes_written. It will be
1523 updated by the kernel as well as by e2fsprogs programs which write to
1524 the filesystem. This is useful for tracking the wear to filesystems
1525 on Solid Sstate Drives.
1527 Fix compatibility issue in the libext2fs info file and makeinfo
1528 version 4.12. (Addresses Red Hat Bugzilla: #481620)
1530 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
1532 Fixed various Debian packaging issues --- see debian/changelog for
1533 details. (Addresses Debian Bug: #506279)
1538 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
1541 Fix various gcc compilation warnings and other programming cleanups.
1542 (Addresses Red Hat Bugzilla: #486997)
1544 Add support for building the blkid command statically.
1546 Add support for disabling the built-in blkid library in favor of a
1547 system-installed blkid implementation via the configure option
1551 E2fsprogs 1.41.4 (January 27, 2009)
1552 ===================================
1554 Fixed a bug which could sometimes cause blkid to return an exit value
1555 of zero for a non-existent device (Addresses Debian Bug: #502541)
1557 Blkid will now recognize ext3 filesystems that have the test_fs flag
1558 set as ext3 filesystems.
1560 The blkid library will now recognize btrfs filesystems and swap
1561 devices currently used by user-level software suspend.
1563 Tune2fs now updates the block group checksums when changing the UUID
1564 to avoid causing e2fsck to complain vociferously at the next reboot.
1566 Tune2fs's inode size resizing algorithms have been fixed so it is not
1567 vastly inefficient for moderate-to-large filesystems, due to some
1568 O(n**2) and O(n*m) algorithms that didn't scale well at all.
1570 Fix tune2fs's inode resizing algorithm so it will not corrupt
1571 filesystems laid out for RAID filesystems; in addition, tune2fs will
1572 refuse to change the inode size for filesystems that have the flex_bg
1573 feature enabled. (This is a limitation in the current implementation
1576 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1577 filesystems with 32-bit block numbers, when the headers for 64-bit
1578 block numbers was added. This regression has been fixed.
1580 Debugfs's ncheck command has been fixed to avoid printing garbage
1581 characters at the end of file names.
1583 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
1584 when shrinking filesystems with uninit_bg feature would not be moved.
1585 In addition, blocks and inode table blocks were not being correctly
1586 freed when shrinking filesystems with the flex_bg feable, which caused
1587 resize2fs -M to fail. Finally, when blocks are moved, make sure the
1588 uninitialized flag in extents is preserved.
1590 Fix bug which caused dumpe2fs to abort with an error if run on a
1591 filesystem that contained an external journal.
1593 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1594 for this in argv[0] to provide better legacy support for these
1595 distributions. This is a practice that should NOT be continued,
1598 Mke2fs now has a new option -U, which allows the user to specify the
1599 UUID that should be used for the new filesystem.
1601 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1602 minus one block. This allows users who have read that ext3 supports
1603 up to 16TB filesystems and who create a 16TB LVM to not get confused,
1604 since the true limit is really 16TB minus one block.
1606 E2fsck will no longer abort an fsck run if block group has an errant
1609 E2fsck now distinguishes between fragmented directories and fragmented
1610 files in verbose mode statistics and in the fragcheck report.
1612 Fix a bug in e2fsck which casued it double count non-contiguous
1613 extent-based inodes.
1615 E2fsck will leave some slack space when repacking directories to allow
1616 room for a few directory entries to be added without causing leaf
1617 nodes to be split right away.
1619 Fix a bug which caused e2fsck to crash when it comes across a
1620 corrupted interior node in an extent tree with the error message:
1621 "Error1: Corrupt extent header on inode XXXXXX"
1623 E2fsck problem descriptions involving the journal are no longer
1624 referred to as "ext3" problems, since ext4 filesystems also have
1627 Fix a long-standing bug in e2fsck which would cause it to crash when
1628 replying journals for filesystems with block sizes greater than 8k.
1630 Update Catalan translation from the Translation Project.
1632 Fixed various Debian packaging issues --- see debian/changelog for
1633 details. (Addresses Debian Bugs: #503057, #502323, #511207)
1638 Fix build of e2fsck.profiled, and add support for building profiled
1639 binaries in the misc directory if configured with --enable-profile.
1641 The ext2fs_open() function now performs more sanity checks on the
1642 superblock to avoid potential divide by zero errors by other parts of
1645 The ext2fs_read_inode_full() function now has a safety check to avoid
1646 a segmentation fault on corrupted filesystems.
1648 The ext2fs_new_inode() function now has a sanity check so that if the
1649 s_first_inode field in the superblock is insane, it will return
1650 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1652 To avoid segmentation faults, ext2fs_block_alloc_stats() and
1653 ext2fs_inode_alloc_stats() now validates the passed inode or block
1654 number to avoid overrunning an array boundary.
1656 Various signed/unsigned errors for variables containing block numbers
1659 Accomodations for gcc's stupidity in not realizing that constant
1660 strings that do not contain a '%' character are safe to use in format
1661 strings have been made so that distributions that want to compile
1662 e2fsprogs with -Werror=format-security have an easier time doing so.
1664 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1666 Added the utility make-sparse.c to the contrib directory.
1668 The ext2fs_block_iterate2() function now reflects errors from
1669 ext2fs_extent_set_bmap() to the caller, if the callback tries to
1670 change a block on an extent-based file, and ext2fs_extent_set_bmap()
1671 fails for some reason (for example, there isn't enough disk space to
1672 split a node and expand the extent tree.
1674 The ext2fs_block_iterate2() function will preserve the uninit flag in
1675 extents when the callback function modifies a block in an extent-based
1678 E2fsck will now flag filesystems that have an insane s_first_ino field
1679 in their superblock, and attempt to use a backup superblock to repair
1683 E2fsprogs 1.41.3 (October 12, 2008)
1684 ===================================
1686 E2fsck has been fixed so it prints the correct inode number for
1687 uinit_bg related problems.
1689 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1690 is available on linux. This can be disabled via a configuration
1691 option in /etc/e2fsck.conf.
1693 Fix a file descriptor leak in libblkid when checking to see if an ext4
1694 or ext4dev module exists.
1696 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1697 while trying to close a filesystem can lead to infinite loops.
1698 (Addresses Red Hat Bugzilla #465679)
1700 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1701 will cause resize2fs to drop into an infinite loop. (Addresses Red
1702 Hat Bugzilla: #465984)
1704 Add a check in the Unix I/O functions in libext2fs so that when a
1705 device is opened read/write, return an error if the device is
1706 read-only using the BLKROGET ioctl.
1708 Fix debugfs's ncheck command so that it prints all of the names of
1709 hardlinks in the same directory.
1711 Fix a bug in libblkid so it correctly detects whether the ext4 and
1712 ext4dev filesystems are available, so that the ext4dev->ext4
1713 fallback code works correctly.
1718 Fix a parallel build problem by making sure util/subst is built before
1719 trying to build the lib/et directory. (Addresses Sourceforge Bug:
1722 Updated "make depend" information for crc16.o
1725 E2fsprogs 1.41.2 (October 2, 2008)
1726 ==================================
1728 Fix e2fsck's automatic blocksize detection. This fixes a regression
1729 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1730 specifies a block number using the -b option if the blocksize option
1731 isn't also specified using -B. Unfortunately, users very commonly
1732 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1733 superblock; in fack e2fsck will often suggest this kind of command
1736 Enhance the debugfs's "ncheck" command so it will print all of the
1737 pathnames for the specified inodes. (Previously, in some cases ncheck
1738 might not print a pathname for an inode at all if some of the other
1739 inodes had multiple hard links.)
1741 Enhance debugfs's "hash" command so the hash seed can be specified via
1742 a command-line option. In addition, allow the hash algorithm to be
1743 specified by name instead of just by number.
1745 Fix e2fsck so that we don't accidentally print the translation file's
1746 header when asking the user a custom question so there is no prompt
1747 defined for a particular problem record. For example, the question
1748 "Run journal anyway" will get the PO header tacked on because e2fsck
1749 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1802 Fix ELF shared library when building on systems that don't already
1803 have the e2fsprogs shared libraries already installed. (Addresses
1804 Sourceforge Bug: #2088537)
1806 Fix the pkg-config files so they work correctly when linking with
1807 static libraries and fix the include directory so programs don't have
1808 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
1809 instead. (Addresses Sourceforge Bug: #2089537)
1811 Make sure ext2fs_swab64() is compiled for all platforms, and not just
1812 for x86. (Addresses Debian Bug: #497515)
1814 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1815 non-x86 platforms. (They had been removed for x86 earlier.)
1817 Fix diet libc compilation support, which had bitrotted due to lack of
1818 TLC. Fixing this improves general portability.
1820 When installing the link library when using ELF shared libraries,
1821 avoid using absolute pathnames if the link library and the shared
1822 library are installed in the same directory. (Addresses Sourceforge
1825 Fix gen-tarball so it will work even if the top-level directory has
1826 been renamed to something other than "e2fsprogs". Also make
1827 gen-tarball print the size of the resulting tar.gz file.
1830 E2fsprogs 1.41.1 (September 1, 2008)
1831 ====================================
1833 Many people are forgetting to update their mke2fs.conf file, and this
1834 causes ext3, ext4, and ext4dev filesystems won't get created with the
1835 proper features enabled. We address this in two ways. First, mke2fs
1836 will issue a warning if there is not definition for an ext3, ext4, or
1837 ext4dev filesystem and the user is trying to create such a filesystem
1838 type. Secondly, when installing from a source build, "make install"
1839 will provide basic configuration file handling for /etc/mke2fs.conf.
1840 If it exists, and does not mention ext4dev, it will be moved aside to
1841 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1842 be installed. If the existing /etc/mke2fs.conf file does mention
1843 ext4dev, then "make install" will install official mke2fs.conf file as
1844 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1845 they should look to see if any changes need to be merged.
1847 The mke2fs program will now create the journal in the middle of the
1848 filesystem, since this minimizes seek times on average for fsync-heavy
1849 workloads. In addition, mke2fs will now create journals using extents
1850 for filesystems that support them. This results in a more efficient
1851 encoding for the journal since it eliminates the need for using
1854 The mke2fs program will avoid allocating an extra block to the
1855 journal. (Addresses Sourceforge Bug: #1483791)
1857 Mke2fs will correctly enforce the prohibition against features
1858 (specifically read-only features) in revision 0 filesystems. (Thanks
1859 to Benno Schulenberg for noticing this problem.)
1861 Mke2fs previously would occasionaly create some slightly non-optimally
1862 placed inode tables; this bug has been fixed.
1864 The mke2fs and tune2fs programs now print the correct usage message
1865 describing the maximum journal size. (Addresses Debian Bug: #491620)
1867 Add support for setting the default hash algorithm used in b-tree
1868 directories in tune2fs (from a command-line option) or mke2fs (via
1869 mke2fs.conf). In addition, change the default hash algorithm to
1870 half_md4, since it is faster and better.
1872 The blkid library will now recognize MacOS hfsx filesystems, and
1873 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1874 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1876 The blkid library has improved detection of JFS and HPFS filesystems.
1877 (Addresses Launchpad Bug: #255255)
1879 The blkid library is now much more efficiently handling devicemapper
1880 devices, mainly by no longer using the devicemapper library. This can
1881 speed up access for systems with a large number of device mapper
1884 Blkid had a number of cache validation bugs in libblkid that have been
1885 fixed. (Addresses Debian Bug: #493216)
1887 Resize2fs will now properly close out the "updating inode references"
1888 progress bar so there is a newline printed before printing the final
1889 "resize is successful" message.
1891 Resize2fs will now correctly handle filesystems with extents and/o
1892 uninitialized block groups correctly when file/directory blocks need
1893 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1894 is not present). To support this, the ext2fs library now supports
1895 initializing inode and block bitmaps that are not yet initialized when
1896 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1897 addition, e2fs_block_iterate2() can now support changing the location
1898 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1899 been optimized to avoid creating unnecessary new extents when updating
1900 the location of blocks in the extent tree. This will also help out
1901 e2fsck's recovery of obscurely corrupted filesystems with extents,
1902 when blocks are claimed by multiple inodes.
1904 Add support for on-line resizing ext4 filesystem with the flex_bg
1905 filesystem feature. The method for doing so is not optimal, but to do
1906 a better job will require kernel support.
1908 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1909 debugfs programs to not be able to read e2image files; the signed
1910 vs. unsigned bug in the code which read bitmaps from the e2image has
1911 been fixed. (Addresses Debian Bug: #495830)
1913 Resize2fs is now correctly managing the directory in-use counts when
1914 shrinking filesystems and directory inodes needed to be moved from one
1915 block group to another. This bug has been around since e2fsprogs
1916 1.26, and is largely harmless, but does cause a filesystem corruption
1917 which will be flagged by e2fsck after the filesystem has been shrunk.
1919 E2fsck will no longer issue spurious complaints about the inode size
1920 caused by very large extent-based files, and by blocks reallocated
1921 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1922 Kernel Bugzilla: #11341)
1924 Mke2fs will now set the creation timestamp on the lost+found directory
1925 and the root directory. (More generally, all new inodes created using
1926 the ext2fs library will correctly set the creation timestamp.)
1928 E2fsck now correctly calculates ind/dind/tind statistics in the
1929 presence of extent-based files. In addition, "e2fsck -v" will report
1930 statistics of the depth of extent trees in the filesystem. E2fsck can
1931 also give an inode fragmentation report using "e2fsck -E fragcheck"
1932 which can be useful when debugging the kernel block allocation
1935 Fix support for empty directory blocks in ext4 filesystems with 64k
1936 blocksize filesystems.
1938 E2fsck will now print the depth of corrupt htree directories.
1940 Debugfs's htree command now correctly understands extent-based
1941 directories. It will also print out the minor hash as well as the
1944 Debugfs has a new command which will print the supported features of
1945 e2fsprogs, to enable scripts to know whether the installed version of
1946 e2fsprogs can support a specific feature.
1948 Debugfs will now write files using extents for filesystems that
1951 The error message printed by "tune2fs -I" if the inode size was too
1952 small was rather confusing, so it has been improved. Also, we won't
1953 try to create an undo log until we know that command-line-specified
1954 parameters such as "tune2fs -I <inode size>" are valid.
1956 Given some filesystems found "in the wild" that had non-zero block
1957 group checksums even though the uninit_bg/gdt_sum feature was not
1958 enabled, e2fsck would issue spurious error messages. Teach
1959 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1960 entirely if the feature flag is not set. (Addresses Debian Bug:
1963 The blkid program will now print out a user-friendly listing of all of
1964 the block devices in the system and what they contain when given the
1965 -L option. (Addresses Debian Bug: #490527)
1967 The filefrag program now has a more accurate calculation for the
1968 number of ideal extents. (Addresses Debian Bug: #458306)
1970 The test I/O manager is now enabled by default, but its overhead is
1971 only incurred when it would be enabled via the TEST_IO_FLAGS or
1972 TEST_IO_BLOCK environment variables.
1974 Typographical errors in various program strings and usage messages
1975 have been fixed; most of these were pointed out by the e2fsprogs
1976 message catalog translators. (Thanks, translators!)
1978 Update and clarified various man pages, as well as some typographical
1979 errors in the libext2fs texinfo file.
1981 Fixed various Debian packaging issues --- see debian/changelog for
1984 Add Indonesian and update French, Polish, Dutch, German, Sweedish,
1985 Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
1991 Fix portability problem with the badblocks group; for systems that
1992 don't have nanosleep(), try using usleep() instead.
1994 The "make check" target in the e2fsck directory now sets
1995 LD_LIBRARY_PATH before running the various e2fsck internal library
1998 The crc32 regression test in the e2fsck library is now portable to
1999 greater varienty of environments, including big-endian systems and
2000 when cross-building e2fsprogs for embedded systems. (Addresses
2001 Sourceforge Bug: #2019287)
2003 The ext2fs_extent_set_bmap() had some bugs when setting the first
2004 block in a file, or when replacing a single block extent. Those cases
2005 fortunately were came up relatively rarely when e2fsck was checking
2006 files, but caused some problems when resize2fs was shrinking
2009 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
2012 Various ext2fs library functions --- ext2fs_block_iterate2(),
2013 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
2014 allocated memory to avoid memory leaks in all of their error return
2017 Ext2ed was failing to build because masix support had been removed in
2018 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
2020 The configure script now respects the LDFLAGS environment variable if
2021 it is set when configure is called. (Addresses Sourceforge Feature
2024 Libuuid is now more portable to the Windows platform. (Addresses
2025 Sourceforge Feature Request: #1937287)
2027 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2028 bare echo commands so that configure flags such as --quiet work
2029 correctly. (Addresses Sourceforge Patches: #2058794)
2031 A few uses of sprintf have been removed from the ext2fs library to
2032 make life easier for bootloaders with a limited libc environment.
2033 (Addresses Sourceforge Bug: #2049120)
2035 The ext2fs_read_inode() checks the validity of the inode number passed
2036 to it earlier, to avoid doing some needless work when it would fail
2039 The ext2fs_open() checks the validity of the blocksize parameter
2040 passed to it earlier, to avoid doing some needless work when it would
2043 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2044 top-level Makefile. That automatic rule is used to better support
2045 SCCS, but it caused problems for a particular niche distribution which
2046 likes to use configure.sh files to store the configure options used to
2047 build a package. Unfortuntaely GNU make will use the configure.sh to
2048 replace the configure script, resulting in a self-inflicted fork bomb
2049 leading to an out-of-memory crash.
2051 To support old GNU C compilers don't use C99/C++ comments, but only
2052 K&R style comments, and don't try to use __builtin_expect if __GNUC__
2053 is less than 3. (__builtin_expect is only supported for gcc versions
2054 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2055 this is an optimization, we only try to use __builtin_expect for gcc 3
2058 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2059 __LITTLE_ENDIAN, which are only defined by glibc's header files and
2060 hence isn't portable.
2062 For the convenience for some distributions that need a static tune2fs,
2063 the Makefile for misc/ now has a tune2fs.static target.
2065 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2066 for extent-based files
2068 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2071 All source files no longer have any trailing white space.
2073 The io_channel_read_blk64() and io_channel_write_blk64() functions are
2074 now functions instead of C preprocessor macros to provide better
2075 forward compatibility.
2077 The e2fpsrogs translation template now expands the @x abbrevation.
2079 Various namespace leackages in libblkid, libe2p, and libext2fs have
2082 Fix a parallel build problem in e2fsprogs.
2084 E2fsprogs is now more portable to Solaris.
2085 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
2087 * Scripts do not assume that /bin/true is always in /bin
2088 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2089 * Flush stdio handles before calling setbuf(), since Solaris will
2090 discard any pending output to the stream.
2091 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2092 picky about which C compiler can beused for SUSv3 conformance.
2093 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2094 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2095 Since we need some SUSv3 functions, consistently use SUSv3 so
2096 that e2fsprogs will build on Solaris using c99.
2097 * Solaris C99 does not support varargs C preprocessor macros
2098 * Solaris header files pollute the C namespace if in/netinet.h
2099 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2101 * Solaris ships with a pathetically ancient shell in /bin/sh so we
2102 avoid the use of various more avanced shell constructs such as $().
2104 The "make rpm" command will now take some extra configure optiosn from
2105 the build environment without needing to patch the source tree.
2107 The ext2fs_add_dir_block() function will now grow the dblist more
2108 aggressively as an optimization to avoid copying the array too often.
2110 The e2fsck_write_bitmaps() will write the block and inode bitmaps
2111 together instead of in two passes.
2114 E2fsprogs 1.41 (July 10, 2008)
2115 ==============================
2117 Add support for ext4 filesystem features, in particular extents,
2118 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
2119 support for checking journal checksums. Debugfs will print new
2120 superblock and inode fields that were defined for ext4. For example,
2121 the nanosecond and i_version fields of an inode, and the
2122 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2123 Note: Resize2fs doesn't currently support the combination of flex_bg
2124 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
2126 Tune2fs can support migrating a filesystem from using 128 byte inodes
2127 to 256 byte inodes, so it can take advantage of the full features of
2130 Add support for "undo" support. E2fsck and mke2fs can optionally
2131 record an undo log which can replayed by the program e2undo.
2133 E2fsck could damage a filesystem by trying to relocate inode tables
2134 due to corrupted block group descriptors, where the attempted inode
2135 table relocation would do far more harm than good. E2fsck has been
2136 fixed to detect this these sorts of corrupted block group descriptors
2137 much earlier in e2fsck processing, so it can try to use the backup
2138 superblock and block group descriptors first. This should be a much
2139 better strategy for recovering these types of corrupted filesystems.
2140 (Addresses Sourceforge Bug: #1840291)
2142 E2fsck will display a more understandable message when the last check
2143 field in the superblock is in the future. (Addresses Debian Bug:
2146 E2fsck now performs more extensive and careful checks of extended
2147 attributes stored in the inode.
2149 Enhance mke2fs to print a more explanatory error message when
2150 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
2153 Fix mke2fs to use a default block size of 4k when formatting an
2154 external journal device. This is done by using a fixed filesystem
2155 type list that consists only of the single filesystem type "journal"
2156 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
2157 Debian Bug: #488663)
2159 Speed up how mke2fs writes the journal data blocks by writing the disk
2160 blocks in larger chunks.
2162 Fix blkid handling of stale devices. Fix a bug which could cause a
2163 core dump while garbage collecting the blkid cache, and assure that
2164 blkid_find_dev_with_tag() never returns a non-existent device. Also,
2165 if a filesystem is found at a new /dev location, eliminate any
2166 duplicate stale entries which can not be verified.
2167 (Addresses Debian Bugs: #487758, #487783)
2169 Add more paranoid checks for LVM volumes and swap partitions in
2170 blkid's probe function, to reduce the chances of false positives.
2172 The mke2fs program now has a much more sophisticated system for
2173 controlling configuration parameters of a newly created filesystem
2174 based on a split filesystem and usage type system. The -t option to
2175 mke2fs was a deprecated alias to -c; it now specifies a filesystem
2176 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2177 separated usage list. The filesystem type information and type
2178 information is used to extract configuration parameters from the
2179 /etc/mke2fs.conf file.
2181 The mke2fs program will no longer complain and request the -f option
2182 when the user tries to create a filesystem with greater than 2**31
2185 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2186 adjust the mke2fs.conf file so filesystems for the Hurd are created
2187 with a blocksize of 4096 and inode size of 128, which is all it knows
2188 how to handle. (Addresses Debian Bug: #471977)
2190 Mke2fs will always make sure that lost+found always has at least 2
2191 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2193 Resize2fs will now print the minimum needed filesystem size if given
2194 the -P option, and will resize the filesystem to the smallest possible
2195 size if given the -M option.
2197 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2198 blocks are consumed during an off-line resize.
2200 The "ls" command in debugfs now supports the -p option, which causes
2201 it to quote the filenames so that spaces or tabs in directory entries
2202 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
2203 Sourceforge Feature Request: #1201667)
2205 Fix a potential off-by-one buffer oveflow in the fs_device_name in an

2209 failures, and error messages can be suppressed with the -f option.
2210 (Addresses Red Hat Bugzilla: #180596)
2212 Fix a bug in badblocks which caused it to overrun an array and likely
2213 crash if more than 8 test patterns are specified using the -t option.
2214 (Addresses Debian Bug: #487298)
2216 Add support to badblocks to limit how quickly it reads from the disk
2217 drive (so it can be used for background scrubbing), and so it will
2218 abort after finding a given number of errors.
2220 Remove support for the legacy big-endian filesystem format which only
2221 existed on extremely long-dead PowerPC kernels almost a decade ago.
2223 Remove MASIX support from e2fsprogs.
2225 Add I/O statistics reporting to e2fsck.
2227 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
2230 Fixed various Debian packaging issues --- see debian/changelog for
2231 details. (Addresses Debian Bugs: #487443, #487675, #490003)

2254 Avoid using predictable filenames in /tmp in blkid's regression test
2255 suite. Also remove bashism's in the regression test script.
2257 If the configure script is given --with-diet-libc, don't use thread
2258 local storage, since diet libc doesn't support TLS. (Addresses
2259 Sourceforge Bug: #2000654)
2261 Fix the blkid regression test suite to tolerate older versions of
2262 mkswap that don't support the -U option.
2264 A few library routines have been converted to support 64-bit block
2265 numbers; in particular, the I/O manager functions, the test_io,
2266 inode_io, and unix_io managers have all be converted to support 64-bit
2269 Debugfs can now be extended for use by test programs. See
2270 lib/ext2fs/extents.c for an example for how it can be used. The test
2271 program links against the debugfs object files, and provides
2272 additional commands by defining an auxiliary libss command table.
2274 The lazy_bg filesystem feature, which was only used by developer's
2275 testing, has been removed since it has been largely supplanted by
2276 uninit_bg. This also simplifies the code.
2279 E2fsprogs 1.40.11 (June 17, 2008)
2280 =================================
2282 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
2283 percentage of reserved blocks. (Addresses Debian Bug: #452639)
2285 Updated Spanish and Catalan translations.
2287 Fixed various Debian packaging issues --- see debian/changelog for

2303 Fix ext2fs_swap{16,32,64} functions so they can be used by external
2304 applications on big-endian machines. (Addresses Debian Bug: #484879)
2307 E2fsprogs 1.40.10 (May 21, 2008)
2308 ================================
2310 When deciding whether or not to revalidate a blkid cache entry, if the
2311 device's mtime is newer than the last time the cached entry was
2312 validated, force a revalidation.
2314 Fix a potential data corruption bug in e2fsck in the journal replay.
2315 The chances of this is happening is extremely remote, especially the
2316 default data=ordered or data=writeback modes. However, if a block
2317 which has been journalled starts with the first four bytes 0xc03b3998,
2318 when e2fsck replays the journal, those four bytes will be replaced
2319 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
2320 metadata to begin with those fatal 4 byte sequence, and unless
2321 data=ordered mode is in use, data blocks are never journaled.
2323 Updated German, Dutch, Sweedish, and Vietnamese translations.
2328 Fixed various Debian packaging issues --- see debian/changelog for
2331 Remove default sizes of types when cross compiling, since autoconf
2332 2.50 can figure this out automatically now.
2335 E2fsprogs 1.40.9 (April 27, 2008)
2336 =================================
2338 SuSE's security team audited uuidd and came up with a few minor
2339 issues. None of them are serious given that uuidd runs setuid as a
2340 unprivileged user which has no special access other than libuuid
2341 directory, but it's good to get them fixed.
2343 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to

2360 Fix fsck so that progress information is sent back correctly when
2361 multiple filesystems are being check and the output of fsck is being
2362 redirected to a file descriptor. Also, include the device name (w/o
2363 spaces) in the progress information sent back via a file descriptor.

2405 E2fsprogs 1.40.8 (March 13, 2008)
2406 =================================
2408 Fixed e2image -I so it works on image files which are larger than 2GB.
2410 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
2411 the size is larger than the number of blocks found in the inode, don't
2412 try to allocate extra empty blocks at the end of the directory to make
2413 up the difference; there's no point to doing that. In addition, if
2414 the size is not a multiple of a blocksize, always fix it.
2416 E2fsck handled a pass 2 "should never happen error" by not giving
2417 enough information and then core dumping. Unfortunately, it was all
2418 too easy to trigger the "should never happen" situation if a
2419 directory's inode size was not correct. This has been fixed, but
2420 e2fsck has also been taught how to handle this situation more
2421 gracefully, by simply removing the inode hash tree information, so
2422 that it can be rebuilt again after e2fsck's pass 3. (Addresses
2423 Launchpad Bug: #129395)
2425 Resize2fs had a bug resizing large inodes with extended attributes
2426 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2427 completely on big-endian systems such as PowerPC. The bug should be
2428 completely fixed now. Yay for regression test suites. (Addresses Red
2429 Hat Bugzilla: #434893)

2437 make it clear that it is just clearing the HTREE information, not the

2445 Add new functions, ext2fs_dblist_get_last() and
2446 ext2fs_dblist_drop_last(), which allows the caller to examine the last
2447 directory block entry added to the list, and to drop if it necessary.
2449 Fixed a portability problem in libblkid with DJGPP.
2451 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
2452 to Philipp Thomas for pointing this out.

2455 fail with an error code.
2458 E2fsprogs 1.40.7 (February 28, 2008)
2459 ====================================
2461 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2462 depreciate the -s option, since it can result in filesystems which
2463 e2fsck can't fix easily. There are very good reasons for wanting to
2464 disable sparse_super; users who wants to turn off sparse_super can use
2465 debugfs. (Addresses Sourceforge Bug: #1840286)
2467 Add missing options to mke2fs's usage message. (Addresses Sourceforge
2470 Fix bug in resize2fs when large (greater than 128 byte) inodes are
2471 moved when a filesystem is shrunk; it was only moving the first 128
2472 bytes, so extended attributes were not getting moved. (Addresses Red
2473 Hat Bugzilla: #434893)
2475 E2fsck now prints an explicit message when the bad block inode is
2476 updated, to avoid confusion about why the filesystem was modified.

2479 Allow mke2fs and tune2fs manipulate the large_file feature.
2480 Previously we just let the kernel and e2fsck do this automatically,
2481 but e2fsck will no longer automatically clear the large_file feature.
2482 It still isn't really necessary to worry about this feature flag
2483 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:

2490 reporting a free block more than once if there are too few free blocks
2491 in the filesystem. (Addresses Sourceforge Bug: #1096315)
2493 Change e2fsck to no longer clear the LARGE_FILES feature flag
2494 automatically, when there are no more > 2GB files in the filesystem.
2495 It's been almost a decade since there have been kernels that don't
2496 support this flag, and e2fsck clears it quietly without telling the
2497 user why the filesystem has been changed.
2499 Fix bug which could cause libblkid to seg fault if a device mapper
2500 volume disappears while it is being probed. (Addresses RedHat

2506 Fix option syntax in dumpe2fs for explicit superblock and blocksize
2507 parameters. What was currently documented in the man page has been
2508 broken for some time, due to getopt() implementation changes. The
2509 option sytax has been changed to one which is can be more portable
2510 supported and which is consistent with the format for extended options

2549 partially filled-in filesystem object on an error, so that e2fsck can
2550 print more intelligent error messages.
2552 Add a new function e2p_edit_feature2() which allows the caller to
2553 specify which feature flags are OK to set or clear, and which returns

2618 ===================================
2620 Fix a potential overflow big in e2image if the device name is too
2623 Mke2fs will now create new filesystems with 256 byte inodes and the
2624 ext_attr feature flag by default. This allows for much better future
2625 compatibity with ext4 and speeds up extended attributes even on ext3
2628 Teach e2fsck to ignore certain "safe" filesystem features which are
2629 set automatically by the kernel. Having the kernel set features
2630 automagically behind the user's back is a bad idea, and we should try
2631 to break the kernel of this habit, especially for the newer ext4
2632 feature flags. But for now, we will try to avoid needless full checks
2633 which can annoy users who are doing fresh installs.
2635 Add support in tune2fs and mke2fs for making a filesystem as being "ok
2636 to be used with test kernel code". This will be needed for using test
2637 filesystems with the latest ext4 kernel code.
2639 Change e2fsck -fD so that it sorts non-htree directories by inode
2640 numbers instead of by name, since that optimizes performances much
2641 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
2643 If e2image fills the disk, fix it so it exits right away instead of
2644 spewing large numbers of error messages.

2647 If ftruncate64() is not available for resize2fs, let it use ftrucate()
2648 instead, but have it check to see if the size would get truncated, and
2649 skip calling ftruncate in that case.
2651 Add support for detecting HFS+ filesystems in the blkid library.
2653 Add supprt in the blkid library for ext4/ext4dev filesystems.
2655 Fix a bug in blkid where it could die on a floating point exception
2656 when presented with a corrupt reiserfs image.
2658 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
2659 such that UUID string is a fixed length.
2661 Add sample python bindings for the uuid library to the contrib
2662 directory. (Addresses-Sourceforge-Patches: #778817)

2668 Allow the debugfs 'undel' command to undelete an inode without linking
2669 it to a specific destination directory, since this might require
2670 allocating blocks that could overwrite some yet-to-be-recovered
2671 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)

2709 Improve time-based UUID generation. A new daemon uuidd, is started
2710 automatically by libuuid if necessary. This daemon is setuid to allow
2711 updates to /var/lib/libuuid, so the clock sequence number can be
2712 stored and so if the clock is set backwards, it can be detected.
2713 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
2716 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2717 superblocks. This avoids e2fsck from concluding that a full
2718 filesystem check is required before backing up the superblock due to
2719 changes in the feature flags. (Addresses Debian Bug: #454926)
2721 Fix fsck to only treat the '#' character as a comment at the beginning
2722 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

2761 E2fsprogs 1.40.3 (December 5, 2007)
2762 ===================================
2764 Fix a potential security vulnerability where an untrusted filesystem
2765 can be corrupted in such a way that a program using libext2fs will
2766 allocate a buffer which is far too small. This can lead to either a
2767 crash or potentially a heap-based buffer overflow crash. No known
2768 exploits exist, but main concern is where an untrusted user who
2769 possesses privileged access in a guest Xen environment could corrupt a
2770 filesystem which is then accessed by the pygrub program, running as
2771 root in the dom0 host environment, thus allowing the untrusted user to
2772 gain privileged access in the host OS. Thanks to the McAfee AVERT
2773 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2775 Fix hueristics in blkid which could cause a disk without partitions to
2776 be incorrectly skipped when a loopback device is present. (Addresses
2777 Red Hat Bugzilla #400321.)
2779 Fix e2image so that in raw mode it does not create an image file which
2780 is one byte too large.
2782 Change mke2fs's usage message so it recommends the preferred -E option
2783 instead of the deprecated -R option.
2785 Enhance the blkid library so it will recognize squashfs filesystems.
2786 (Addresses Red Hat Bugzilla #305151.)
2788 Enhance e2fsck so it will force the backup superblocks to be backed up
2789 if the filesystem is consistent and key constants have been changed
2790 (i.e., by an on-line resize) or by e2fsck in the course of its
2793 Enhance blkid's detection of FAT filesystems; so that USB disks with
2794 only a single bootable partition will not get missed.
2796 E2fsck will no longer mark a filesystem as invalid if it has time
2797 errors (i.e., if superblock mount time or last write time is in the
2798 future) and the user refuses to fix the problem.
2800 The Ubuntu init scripts don't properly set the system time correctly
2801 from hardware clock if the hardware clock is configured to tick local
2802 time instead of GMT time. Work around this as best as we can by
2803 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2804 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2807 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2808 Hat Bugzilla #151533.)
2810 Fix e2fsck so that if the superblock is corrupt, but still looks
2811 vaguely like an ext2/3/4 superblock, that it automatically tries to
2812 fall back to the backup superblock, instead of failing with a hard
2815 Make the e2fsprogs program more robust so that they will not crash
2816 when opening a corrupt filesystem where s_inode_size is zero.
2818 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2819 arguments are detected as such and the parse error is reported to the
2820 user. (Addresses Debian Bug #435381.)
2822 Change e2fsck so it will not complain if a file has blocks reallocated
2823 up to the next multiple of a system's page size.
2825 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2826 about (valid) filesystems where the inode table extends to the last
2827 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2829 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2830 allocating inode tables for some relatively rare odd disk sizes.

2833 Add Catalan translation and update Dutch and Swedish translations
2834 from the Translation Project.
2836 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2837 still had an issue when trying to figure out whether we need to
2838 byte-swap fast symlinks that contained extended attributes.
2840 Fixed spelling mistakes, typos, and otherwise clarified man pages.

2847 Fix mke2fs tests to avoid needing any significant ^M (CR) characters

2851 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2852 works correctly when the prefix is not the root directory.
2854 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2855 clena up after themselves by deleting the test.img temporary file
2856 after completing the test.
2858 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2859 first directory entry in a directory block and the last directory
2860 entry in the previous directory block is not in use. Fortunately
2861 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2862 places where it is extremely unlikely to run into this corner case.
2864 Fix missing dependency which would cuase parallel builds to fail.
2865 (Addresses Sourceforge Bug #1842331.)
2867 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2868 calling open(O_CREATE) with a missing mode parameter.

2875 are properly passed back up through the call stack.
2877 E2fsprogs 1.40.2 (July 12, 2007)
2878 ================================
2880 A recent change to e2fsck_add_dir_info() to use tdb files to check
2881 filesystems with a very large number of filesystems had a typo which
2882 caused us to resize the wrong data structure. This would cause a
2883 array overrun leading to malloc pointer corruptions and segfaults.
2884 Since we normally can very accurately predict how big the the dirinfo
2885 array needs to be, this bug only got triggered on very badly corrupted
2888 Fix a bug in e2fsck which caused it to incorrectly salvange
2889 directories when the last entry's rec_len is bogusly too big. This
2890 resulted in a nonsense filesystem corruption to be reported, and
2891 required a second run of e2fsck to fully fix up the directory.

2901 ===============================
2903 Fix bug which could cause libblkid to loop forever. When revalidating
2904 a partition where there is obsolete information in /etc/blkid.tab, we
2905 end up freeing a the type tag without clearing dev->bid_type, causing
2906 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2908 The Turkish translation has a bug in it where it has the translation
2909 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2910 @E, recursively, forever, until the stack fills up and e2fsck core
2911 dumps. We fix this by making e2fsck stop @-expansions after a
2912 recursive depth of 10, which is far more than we need.
2913 (Addresses Sourceforge Bug: #1646081)
2915 Compile the default mke2fs.conf into mke2fs program. People are
2916 getting surprised by mke2fs creating filesystems with different
2917 defaults than earlier versions of mke2fs if mke2fs.conf is not
2918 present. So we now create a built in version of mke2fs.conf file

2922 Improve the config/parse_types.sh helper script. Fix a potential
2923 security problem if e2fsprogs is built as root (as Gentoo does!). In
2924 addition fix the script and how it is called from the configure script
2925 so that it does the right thing when cross-compiling. (Fixes Gentoo
2928 Update Vietnamese, French, and Dutch PO files from the Translation
2929 Project. Also created a new e2fsprogs.pot file for translator.
2931 Fix bogus strip permission errors when building under Debian. When
2932 building the e2fsprogs dpkg's, the dh_strip command emits a large
2933 number of error messages caused by the permissions not being right.
2934 So run dh_fixperms before running dh_strip.
2939 Add new function: profile_set_default(). This function sets the value
2940 of the pseudo file "<default>". If the file "<default>" had
2941 previously been passed to profile_init(), then def_string parameter
2942 will be parsed and used as the profile information for the "<default>"
2945 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2946 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2947 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2949 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2950 priority" environment variable that overrides all others, where as
2951 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2952 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2953 the all the rest are set. This will assure that the locale when
2954 running the test suites is the "C" locale. (Obviates Gentoo patch:

2961 Fix divide by zero error in blkid's NTFS probing logic.
2963 Add new blkid -g option which causes the blkid cache to be garbage
2966 Fix a bug in libblkid which could cause the internal field bid_type to
2967 become corrupted. Fortunately bid_type isn't used much, and bid_label
2968 and bid_uuid is only used by debugging code, so the impact of this bug

2972 created with a requested RAID stride, and then use it automatically in
2975 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2976 isn't too big. In some cases Lustre users have tried specifying an
2977 inode size of 4096 bytes, while keeping an inode ratio of one inode
2980 Improve sanity check in e2fsck's algorithm for finding a backup
2981 superblock, so that it won't accidentally find a superblock that was
2982 located in the journal, and then later reject it as being not a valid
2985 Fix e2fsck get_size logic so that it will work with the Linux floppy
2986 driver. The Linux floppy driver is a bit different from the other
2987 block device drivers, in that if the device has been opened with
2988 O_EXCL, it disallows another open(), even if the second open() does
2989 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2991 Fix error checking of badblock's last-block and start-block arguments.

3010 Fix e2fsck so that it updates the journal inode if it is corrupted and
3011 the backup journal information from the superblock was successfully
3012 used to recover the filesystem.
3014 Fix e2fsck so that it checks all of the blocks in the journal inode
3015 for validity. The original code only checked the direct blocks to
3016 make sure the journal inode was sane. Unfortunately, if some or all
3017 of the indirect or doubly indirect blocks were corrupted, this would

3022 Add extra sanity checks for extended attributes in the case where the
3023 size is zero but the offset is very large.
3025 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3026 and ext2fs_get_next_inode_full().
3028 Clarify the copyright licenses used by the various libraries in
3029 the top-level COPYING file (Red Hat Bugzilla: 166058)
3031 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3033 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3035 Remove check in e2fsck which requires EA's in inodes to be sorted;
3036 they don't need to be sorted, and e2fsck was previously wrongly
3037 clearing unsorted EA's stored in the inode structure.
3039 Allow mke2fs or tune2fs to create a substantially larger journal (up
3040 to 10,240,000 blocks).
3042 Fix MD superblock detection, and make sure the correct UUID is
3043 reported from the MD superblock.
3045 Fix a signed vs. unsigned bug in debugfs.
3047 Enhance debugfs's date parser so that it accepts integer values.
3049 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3050 file with multiply claimed blocks is hard linked. or not at all if the
3051 root directory contains shared blocks
3053 Enhance debugfs so it can modify the block group descriptors using the
3054 command set_block_group_descriptor.
3056 Improve e2fsck's reporting of I/O errors so it's clearer what it was
3057 trying to do when an error happens
3059 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3060 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:

3077 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3078 field on the first pass.
3080 Fix e2fsck to set the file type of the '..' entry when connecting
3081 a directory to lost+found. (Addresses Lustre Bug: #11645)
3083 Enhance e2fsck to recover directories whose modes field were corrupted
3084 to look like special files. This is probably only useful in
3085 artificial test cases, but it will be useful if we ever do the "inodes
3086 in directory" idea for ext4.
3088 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
3091 Fix resize2fs parsing of size parameter (in sector units). This was
3092 actually a bug in libe2p's parse_num_blocks() function. When handling
3093 the 's' suffix, it was ignoring the blocksize information passed in
3094 from the caller and always interpreting the number in terms of a 1k
3095 blocksize. (Addresses Debian Bug: #408298)
3097 There was a floating point precision error which could cause e2fsck to
3098 loop forever on really big filesystems with a large inode count.

3101 Fix memory leak in ext2fs_write_new_inode()
3103 Add support for using a scratch files directory to reduce e2fsck's
3104 memory utilization on really big filesystems. This uses the TDB
3105 library. See the [scratch_files] section of the e2fsck.conf man page
3108 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
3109 platform (Addresses Debian Bug: #397044)

3114 Allow debugfs and dumpe2fs to support fs features under development.
3116 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3117 ext2fs_open() , which allows application to open filesystes with features
3118 which are currently only partially supported by e2fsprogs.
3120 Allow unix_io to support offsets greater than 2G (Addresses
3121 SourceForge Bug: #1547922)
3123 Fixed overflow and signed/unsigned problems caused by the number of
3124 blocks or inodes exceeding 2**31 or being close to 2**32-1.
3126 Add support for unsigned directory hash calculations with hints in the
3127 superblock to fix cross-architectural portability for htree
3128 directories with filenames where the high 8th bit is set. (Addresses

3135 Require mke2fs -F -F for really dangerous operations, since -F is
3136 needed for less dangerous operations such as creating filesystems
3137 images in regular files, or creating filesystems on whole block

3139 with running mke2fs on an apparently-mounted or in-use filesystem.
3141 Allow the default inode size to be specified into the mke2fs.conf
3144 Make the smallest default journal size is big enough so that on-line
3145 resizing should always work.

3153 Fix debugfs display bug us that bytes that have the high bit set are
3154 displayed as "ec" instead of "ffffffec".
3156 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3158 Device mapper scanning wasn't working in the blkid library because the
3159 pathnames had an extra "/dev" when they were being probed.
3161 Add GFS/GFS2 support to the blkid library.
3163 Fix blkid support of empty FAT filesystem labels.
3165 Avoid recursing forever (or for a long time) when the blkid library
3166 searches for a device and there are symlinks to directories in /dev.
3168 Avoid unaligned halfword access in blkid when accessing FAT
3169 superblocks, as this will cause Sparc/Solaris systems to throw a

3179 the superblock. Omit by default printing superblocks that are likely
3180 found in located in an ext3 journal unless an explicit -j option is

3184 translation. (Addresses Debian bug: #411562)
3186 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3187 determining a partition's size, since binary searching to determine
3188 the device doesn't work on FreeBSD.
3190 Documentation about UUID's is available in enough places, and it's
3191 awkward to deal with debian-legal's insanities. So I'm caving in the
3192 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3193 don't have do the dfsg tarball. Also remove the rule that only tried
3194 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3195 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
3197 Fix the info-dir line so that the menu name does not contain a .info
3198 prefix. First of all, it's ugly, secondly, it causes the install-info

3218 (Addresses Sourceforge Bug: #1565561)
3220 Remove unused variables and other lint/gcc -Wall cleanups
3222 Add check to ext2fs_get_device_size() so it will return EFBIG for for
3223 filesystems contained in regular files where the filesystem image size
3224 is returned by stat64().
3226 Set local environment variables to C so mk_cmds and compile_et always
3227 work. (Addresses SourceForge Bug: #1532177)
3229 Added the 64-bit byte swapping function ext2fs_swab64().
3231 Added two new helper functions to prevent 2**31/2**32-1 overflow
3232 problems: ext2fs_div_ceil() and e2p_percent().
3234 Create new ext2fs library inline functions ext2fs_group_first_block()
3235 and ext2fs_group_last_block() in order to calculate the starting and
3236 ending blocks in a block group.
3238 Create the generated files read-only to remind developers not to edit them.
3240 Add support for autoconf 2.60 (with backwards compatibility for older
3241 versions of autoconf).
3243 Added an "make rpm" target to top-level Makefile
3245 Added various FreeBSD portability fixes.
3247 Exclude mercurial files from the RPM build tree to speed up copy/build.
3249 Use root_sysconfdir to define the locations of mke2fs.conf and
3250 e2fsck.conf instead of using a hard-coded /etc pathname.
3252 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3254 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3256 If diff -u is supported, use it to report test failures.
3258 Updates/improvements to RPM spec file
3260 Add on-disk format definitions for the following new features:
3261 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3262 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3263 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3265 Add a new make target "checked-failed" in the tests directory which
3266 reruns any failed tests
3268 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3270 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3271 pointer dereferences, memory leaks, etc. None were security-criticial
3274 Fix up usage and decrement error messages in the test_icount program
3276 Add debugging code to the com_err library; if the environment variable
3277 COMERR_DEBUG is set to 1, print out debugging messages as error tables
3278 are added and removed from the com_err library. If the
3279 COMERR_DEBUG_FILE environment variable is set (and the process is not
3280 setuid) the debugging messages may be redirected to a file.
3282 Change all of the e2fsprogs programs to use the newer add_error_table()
3283 and remove_error_table() interfaces instead of the much older
3284 initialize_*_error_table() function.
3286 Add TDB support into the ext2fs library. This allows us to have a
3287 guaranteed library we can count on always being present so we can
3288 store data in an on-disk database.
3290 Add support for using TDB to store the icount data, so we don't run out
3291 of memory when checking really large filesystems.
3293 Change the regression test suite so that it skips empty test directories.
3295 Define the l_i_iversion field in ext2_inode. The l_i_version field is
3296 now defined from the old l_i_reserved1 field in the ext2 inode. This
3297 field will be used to store high 32 bits of the 64-bit inode version
3300 Add Makefile production rule for e2fsprogs.spec in case it gets
3303 Add new function profile_get_uint() to allow for a clean way to fetch
3304 unsigned integers from the context.
3306 Add test to make sure the ext2 superblock structure is 1024 bytes.
3308 Fix typo in name of f_dup4 regression test
3310 Add new function blkid_gc_cache() which performs a garbage collection
3311 pass on the /etc/blkid.tab file.
3313 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
3314 general, only e2fsck (after the filesystem is clean), tune2fs, and
3315 resize2fs should change the backup superblocks by default. Most
3316 callers of ext2fs_open() should not be touching any superblock fields
3317 which require the backups to be touched.
3319 Add new function to libext2fs, ext2fs_default_journal_size(), which
3320 returns the default journal size.
3323 E2fsprogs 1.39 (May 29, 2006)
3324 =============================
3326 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3327 between 2**31 and 2**32 blocks.
3329 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3330 configure the filesystem features, blocksize, and inode_ratio for
3331 different filesystem types.
3333 Mke2fs will now create filesystems hash trees and on-line resizing
3334 enabled by default, based on the new /etc/mke2fs.conf file.
3336 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3337 filesystem device node in exclusive mode to prevent accidents by
3338 system administrators. In the case of resize2fs and mke2fs, it will
3339 only use exclusive mode if the filesystem is not mounted.
3341 Fixed a bug in mke2fs which caused it to to fail when creating the
3342 resize inode for large filesystems. (Addresses Debian Bug #346580)
3344 When allocating space for the RAID filesystems with the stride
3345 parameter, mke2fs will now place each portion of the group's inode
3346 table right up after the superblock (if present) in order to minimize
3347 fragmentation of the freespace.
3349 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3350 efficiently by writing the inode and block bitmaps in one pass, thus
3351 reducing the number of disk seeks required.
3353 Add support for on-line resizing to resize2fs.
3355 Fix blkid library so that logic to determine whether or not a device's
3356 cached information in /etc/blkid.tab needs to be verified or not
3357 doesn't get confused by a system clock which is insane (for example,
3358 if the battery is dead on a Macintosh running PPC Linux. (Addresses
3359 Red Hat Bug: #182188)
3361 The blkid library will now store the UUID of the external journal used
3362 by ext3 filesystems, so that in the future, the userspace mount binary
3363 can use this to find the location of the external journal and pass
3364 this information to the kernel.
3366 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3367 control how various options should be handled. See the e2fsck.conf
3368 man page for more details. (Addresses Debian Bug: #150295)
3370 E2fsck now prints an explanatory message when delaying a filesystem
3371 check when the system is running on battery. (Addresses Debian Bug:
3374 E2fsck will detect if the superblock's last mount field or last write
3375 field is in the future, and offer to fix if so. (Addresses Debian Bug
3376 #327580) These problems will be fixed automatically in preen mode
3377 since Debian's boot sequence bogusly doesn't set the time correctly
3378 until potentially very late in the bootup process, and this can cause
3379 false positives which will cause users' systems to fail to boot.
3380 (Addresses Debian Bugs #343662 and #343645)
3382 E2fsck now checks to see if the superblock hint for the location of
3383 the external journal is incorrect, and if so, offer to update it.
3384 (Addresses Debian Bug: #355644)
3386 Fix e2fsck from segfaulting on disconnected inodes that contain one or
3387 more extended attributes. (Addresses Debian Bug: #316736, #318463)
3389 E2fsck will stop and print a warning if the user tries running a
3390 read/write badblocks test on a read-only mounted root filesystem.
3392 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
3393 C. Thompson for pointing these out; they were originally found using
3396 When resizing a file containing a filesystem, resize2fs will expand or
3397 truncate a file as necessary. (Addresses Debian Bug: #271607)
3399 Resize2fs will now automatically determine the RAID stride parameter that
3400 had been used to create the filesystem, and use that for newly created
3401 block groups. The RAID stride parameter may also be manually specified
3402 on the command line using the new -S option to resize2fs.
3404 Fix mke2fs so that it correctly creates external journals on
3405 big-endian machines (such as a S/390).
3407 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3408 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
3409 Chambraud for pointing this out.)
3411 Dumpe2fs will now print the size of the journal (if present).
3413 Fix debugfs's set_inode_field command so it can properly set the frag,
3414 fsize, uid_high, gid_high, and author fields in the inode instead of
3415 silently failing, and so that setting the i_size actually sets i_size
3418 Add a new debugfs command, set_current_time, which sets fs->now so
3419 that regression test suites can repeatedly modify the filesystem's
3422 Fix a bug in debugfs's icheck which would incorrectly report the owner
3423 of an extended attribute block.
3425 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3426 print a usage message when an illegal option character is given.
3428 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3429 so it won't core dump. (Addresses SourceForge bug #1424311)
3431 Fix mklost+found so that it creates a full-sized directory on
3432 filesystems with larger block sizes.
3434 Fix a file descriptor leak in blkid library.
3436 Fix a display bug in "badblocks -sv" so that the done message properly
3437 clears the block number at the end of the test. (Addresses Debian Bug

3448 that the "best" (i.e., leaf) device is probed by the blkid library.
3450 Fix the blkid library so that it notices when an ext2 filesystem is
3453 Improve the blkid's library VFAT/FAT detection; it now understands
3454 labels stored in the root directory, and is more paranoid about
3455 checking the FAT superblock values.
3457 Fixed a fd leak in the uuid library which was causing problems for the
3458 LVM tools. (Addresses Debian Bug: #345832)
3460 Add support for the reiser4 and software suspend partitions to the
3461 blkid library. Also add support for extract the label from iso9660
3464 Fix a compile_et bug which miscount the number of error messages if
3465 continuations are used in the .et file.
3467 Add extra sanity checks to protect users from unusual cirucmstances
3468 where /etc/mtab may not be sane, by checking to see if the device is
3469 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug

3492 Update config.guess and config.sub to latest version (2006-02-23) from
3495 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
3496 Bugs: #360661, #360317)
3498 Fixed the Makefile so that they work correctly on newer versions of
3499 GNU make (i.e., 3.81).
3501 Add valgrind support to the regression test suites, and eliminate
3502 false positives from valgrind.
3504 Add a regression test suite for the blkid library.
3506 Fix a fencepost error in resize2fs caught by valgrind.
3508 Fix compiler warnings about missing memcpy prototypes.
3510 We no longer have the sparc assembly code in the header file any more,
3511 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
3512 break compiles on the sparc architectures when using gcc.
3514 In the libext2fs library, add the new field fs->now which if non-zero
3515 is used instead of the system time when setting various filesystem
3516 fields (last modified time, last write time, etc.)
3518 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3519 ext2fs.h which is needed since the inline functions use memcpy().
3520 (Addresses Sourceforge Bug #1251062)
3522 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3523 the build system when building files in the util directory which are
3524 needed during the build process. This avoids potential problems when
3525 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3526 are not recognized as valid by the host compiler. (Addresses
3527 Sourceforge Bug #1261547)
3529 Clean up the blkid library by making the superblock and generic i/o
3530 functions to be more generic. Clean up interface to the probe
3531 function, and fix memory leak. Finallly, remove an unneeded reference
3532 to probe.h in the lib/blkid/resolve.c
3534 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3535 of invalid block #'s.
3537 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3538 indicate that the the function read/writes the memory location.
3540 Fix various gcc -Wall complaints.
3542 Add a dependency to make sure that the subdirectories are created
3543 before creating all of the object files, in order to address parallel
3544 build problem in the library Makefiles. (Addresses Sourceforge Bug:
3547 Add $(LDFLAGS) to the command line argument when generating an ELF or
3548 Solaris shared library, to allow cross-compile and other builds that
3549 might need to specify -L paths to needed libraries. (Addresses
3550 Sourceforge Bug #1261549)
3552 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3553 intended for testing purposes. It allows an ext2/ext3 developer to
3554 create very large filesystems using sparse files where most of the
3555 block groups are not initialized and so do not require much disk
3556 space. Eventually it could be used as a way of speeding up mke2fs and
3557 e2fsck for large filesystem, but that would be best done by adding an
3558 RO_COMPAT extension to the filesystem to allow the inode table to be
3559 lazily initialized on a per-block basis, instead of being entirely
3560 initialized or entirely unused on a per-blockgroup basis.
3562 Fix backwards compatibility so e2fsprogs will better compile on Linux
3565 Make test scripts more robust against locale-related environment variables
3567 Fix type warning problem with sizeof() in ext2fs_open2().
3569 Fix type warning problem with time_t in debugfs.
3572 E2fsprogs 1.38 (June 30, 2005)
3573 ==============================
3575 Fix blkid's test programs (built with "make check") compile correctly
3576 even without "configure --enable-blkid-debug".
3578 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3579 type aliasing rules on newer gcc compilers. (Addresses Red Hat
3582 Fix com_err library to make it more compatible with recent changes
3583 made to the com_err library in MIT Kerberos V5 version 1.4.
3584 (Addresses Sourcefroge Bug #1150146)
3586 General cleanup of messages printed by e2fsprogs programs for grammar,
3587 consistency, and to make life easier for translators. Fixed a few
3588 strings containing English that had not been marked as needing
3589 translations. Removed strings that do not need to be translated, to
3590 make life easier for translators.
3592 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3593 test to see if a device appears to be in use instead of just relying
3594 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
3596 Fix portability problem in the filefrag program affecting platforms
3597 where the size of an integer is smaller than the size of a long.
3598 (Addresses Debian Bug #309655)
3600 Mke2fs will now use a larger journal by default for filesystems
3601 greater than 4GB. (128 MB instead of 32MB).
3603 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3604 unless forced. This is to avoid signed vs. unsigned kernel bugs in
3605 block numbers that still need to be fixed.
3607 The blkid program has a new option which will more efficiently search
3608 for device when it is known (or expected) that only one matching
3609 device will be found in the system, such as when doing a lookup by
3612 Debian's e2fsprogs-specific initrd fragment will avoid including
3613 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3614 and LD_LIBRARY_PATH, and filtering out libraries found in
3615 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
3617 Fixed a potential portability issue in the blkid programs for
3618 architectures where the char type is unsigned. (Addresses Sourceforge
3621 Fix a bug in filefrag so that it doesn't falsely count an extra
3622 discontinuity when the first block found is an indirect block.
3623 (Addresses Debian Bug #307607).
3625 Fix blkid's recognition of cramfs filesystems, and enhance it to be
3626 able to handle cramfs labels.
3628 Fix debugfs's stat command to not core dump when a filesystem is not
3631 Fix e2fsck's handling of error conditions caused by the resize inode
3632 claiming blocks that are also used by other inodes, a filesystem
3633 corruption which was commonly caused by a bug in Fedora Core 3's
3636 Fixed bug in filefrag which caused it to fail on non-ext2/3
3637 filesystems. (Addresses Debian Bug: #303509)
3639 If the superblock last mount time indicates that the system clock may
3640 not be accurate, then e2fsck will omit checking inodes' deletion time
3641 field for indications of a potential corrupted orphaned inode list.
3642 (Previously e2fsck only ommited these LOW_DTIME checks when the
3643 superblock's last write time looked insane.)
3645 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
3646 (Addresses Debian bug #302200)
3648 Make the blkid library more paranoid about being run from setgid
3649 programs, and to use __secure_getenv() from libc if it is available.
3651 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3652 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
3653 and Sourceforge Bug: #1189803)
3655 Updated and fixed translations.
3657 Fixed various Debian packaging issues --- see debian/changelog for
3663 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3664 changed to take an unsigned int for the bit number. Negative bit
3665 numbers were never allowed (and didn't make any sense), so this should
3666 be a safe change. This is needed to allow safe use of block numbers
3667 greater than or equal to 2**31.
3669 The compile_et program will avoid recreating generated foo_err.c and
3670 foo_err.h files if no changes are necessary. The compile_et program
3671 will also atomically replace these files to avoid a potential parallel
3672 build race problem on SMP systems. (Addresses Sourceforge Bug:
3675 Added a new function to the blkid library, blkid_probe_all_new(),
3676 which only probes newly added disk devices, and change
3677 blkid_find_dev_with_tag() to use this function so that when a
3678 requested tag is not found, devices that were previously not checked
3679 are searched before searching all devices in the system.
3681 Added new functions to the blkid library, blkid_dev_set_search() and
3682 blkid_dev_has_tag().
3684 E2fsck's problem strings can now use @m and @n as abbrevations for
3685 "multiply-claimed" and "invalid", respectively.
3687 The e2fsprog.pot file now has an explanation of how the @-expansion
3688 and %-expansion works, and strings in e2fsck/problem.c which contain @
3689 characters now have comments in e2fsprogs.pot with the @-expansion to
3690 make life easier for translators.
3692 Fixed missing return values in the ext2fs library which could cause it
3693 to return random garbage in certain error conditions.
3695 Allow the current time to be overriden via the E2FSCK_TIME environment
3696 variable for use in regression tests.
3698 The test scrpit driver program now exits with a non-zero status if
3699 there any of its test that it ran failed.
3701 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
3704 Fixed "make check" so that it compiles correctly even when e2fsprogs'
3705 header files have not be installed in the system include directories.
3706 (Addresses Sourceforge Bug: #1180572)
3708 Fixed gcc -Wall nits.
3711 E2fsprogs 1.37 (March 21, 2005)
3712 ===============================
3714 Add support for checking the validity of Extended Attributes stored in
3717 Add support for dumping the contents of large inodes to debugfs,
3718 including the extended attributes stored in inodes.
3720 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3721 when we create a new inode we make sure that the extra information in
3722 the inode (any extra fields in a large inode and any ea-in-inode
3723 information) is initialized correctly. This can take place when
3724 mke2fs creates the root and lost+found directory, when e2fsck creates
3725 a new root inode or a new lost+found directory, and when the user uses
3726 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3727 create inode could inherit garbage (or old EA information) from a
3728 previously deleted inode.
3730 Fixed a bug in e2fsck so it would notice if a file with an extended
3731 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3734 Added support to filefrag to detect files which are using the new
3735 experimental file extents format, and use the non-ext2 algorithm in
3736 that case. Fixed a bug to avoid reporting a false discontinuity if
3737 there is one or more unallocated blocks at the beginning of a file.
3739 Duplicated a check for noticing whether or not the number of blocks
3740 (given a certain blocksize) is greater than 2**32 when the
3741 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3742 allows mke2fs to automatically use a larger blocksize when creating a
3743 filesystem on a very large device when run on systems that do not
3744 support BLKGETSIZE64.
3746 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3747 build system had been switched to treat the .gmo files as shipped
3748 files (for backwards compatibility with systems that have older GNU
3749 I18N tools installed), but the gen_tarball.in script was still
3750 removing the .gmo files from the official source distribution.
3752 Fixed various Debian packaging issues --- see debian/changelog for
3753 details. (Addresses Debian Bugs ##296769, #299341)
3758 Added new functions to the e2p library which convert between a string
3759 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3760 make the generated binaries more compact.
3762 Fixed a compile-time error on Darwin systems.
3764 Cleaned up the lib/ext2fs Makefile slightly.
3767 E2fsprogs 1.36 (February 4, 2005)
3768 =================================
3770 All of the patches that were applied to Fedore Core 3's
3771 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3772 lot of bug fixes first. Users of Fedora Core 3 are strongly
3773 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3775 Add support for filesystem with the online resizing via resize inode
3776 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3777 patches also didn't bother to do any consistency checking on the
3778 resize inode, or add any tests to the regression test suite. The "-R
3779 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3780 being listed in mke2fs's usage message. All of these shortcomings
3781 have been corrected.
3783 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3784 program. In order to do this, the user must run the commands:
3786 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3787 e2fsck -f /dev/hdXXX
3789 Optionally, the ext2prepare command can be used to re-enable online
3790 resizing after the filesystem has been fixed.
3792 The fsck program will now accept an optional filedescriptor argument
3793 to the -C option. (The Fedora version of this patch would sometimes
3794 cause fsck to ignore a parameter on fsck's command line in some rare
3797 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3800 Make sure resize2fs releases the blocks belonging to the old inode
3801 table blocks when moving the inode table. (Addresses Debian Bug:
3804 Skip the r_resize_inode test if resize2fs is not compiled (due to
3805 configure --disable-resizer)
3807 E2fsck now checks the summary filesystem accounting information, and
3808 if any of the information is obviously wrong, it will force a full
3809 filesystem check. (Addresses Debian Bug #291571)
3811 Fix e2fsck to not complain when the resize_inode feature is enabled,
3812 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3815 Fix e2fsck to note delete symlinks that contain an extended attribute
3816 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3819 Add new utility program, copy_sparse.c, which is very useful
3820 for dealing with large sparse files (such as e2image files).
3822 Add support for jnl_blocks[] for debugfs's set_super_value.
3824 Fix filefrag so that it works correctly with sparse files.
3826 Filefrag -v will print first and last blocks.
3828 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3831 Add mke2fs support so that it can support filesystems larger than 4TB
3832 automatically, by retrying with a 4k blocksize if the device size is
3833 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3836 Change blkid to test for NTFS first because Windows sometimes doesn't
3837 clear enough of the parition to confuse the probing routines into
3838 thinking the old filesystem type is still valid. (Addresses Debian
3841 Add support for swap partition label and uuid's in the blkid library.
3843 Add support to the blkid library to recognize Oracle ASM volumes.
3845 Make blkid -t display all devices that match the specified criteria,
3846 not just the first one, and work more consistently when the blkid
3847 cache file is not available or set to /dev/null. (Addresses Debian
3848 Bug #290530 and #292425)
3850 Badblocks will now correctly display block numbers greater than
3851 999,999,999 in its progress display.
3853 The tune2fs program will not allow the user from setting a ridiculous
3854 number of reserved blocks which would cause e2fsck to assume the
3855 superblock was corrupt. E2fsck's standards for what is a ridiculous
3856 number of reserved block has also been relaxed to 50% of the blocks in
3859 The blkid library will return vfat in preference to msdos, and ext3 in
3860 preference to ext2 (if the journalling flag is set) so that mount will
3861 do the right thing. (Addresses Debian bug #287455)
3863 Mke2fs will now use the -E option for extended options; the old -R
3864 (raid options) option is still accepted for backwards compatibility.
3865 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3867 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3868 (via "32m" or "4g" on the command line) if the user finds this more
3869 convenient than specifying a block count.
3871 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3872 cache conherency problem.
3874 Debugfs now supports a new command, set_inode_field, which allows a
3875 user to manually set a specific inode field more conveniently, as well
3876 as set entries in the indirect block map.
3878 Debugfs's set_super_value command has been enhanced so that the user
3879 can set most superblock fields, including the date/time fields and
3880 some of the more newsly added superblock fields.
3882 E2fsprogs programs now accept an offset to be passed to the file
3883 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3885 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3886 support on the x86 doesn't exist for now, but it can be useful on
3887 other architectures with page sizes greater than 4k. There are 2.6
3888 kernel patches out there which enable this, but they are of this
3889 writing still experimental.
3891 The e2image command now takes the -s option which will scramble
3892 directory entries for raw image files.
3894 Fix a file descriptor leak in the filefrag program.
3896 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3899 Fix bug in debugfs where kill_file would lead to errors when deleting
3900 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3902 Fix bug in the blkid library when detecting the ocfs1 filesystem
3904 Remove obsolete EVMS 1.x and a.out DLL support.
3906 E2fsck will attempt to recover from a journal containing illegal blocks.
3908 Fixed two potential ordering constraint problems in e2fsck which might
3909 cause the filesystem to be corrupted if e2fsck is interrupted during a
3910 (extremely narrow) race window. Thanks to Junfeng Yang from the
3911 Stanford Metacompilation group for pointing this out.
3913 Fixed bug in e2fsck where it would not accurately detect whether or
3914 not the system is running on adaptor if the ACPI device representing
3915 the AC adapter didn't correspond to the what was used on IBM
3918 Change e2fsck to accept directories greater than 32MB.
3920 Fix e2fsck so that a checkinterval of zero disables a time-based check
3923 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3924 to the PAGER environment variable. (Addresses Debian Bug #239547)
3926 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3929 The debugfs program will set the filetype information when creating a
3932 Add debugfs -d option to use a separate source of data blocks when
3933 reading from an e2image file.
3935 Add e2image -I option which allows the e2image metadata to be
3936 installed into a filesystem.
3938 Fixed bug in the badblocks program which caused "done" to always
3939 appear in english even when a translation was available. (Addresses
3942 The blkid program has a new option -o which controls the output format
3943 of the blkid program; this is makes blkid more convenient to use in
3946 Fix a minor bug in uuid library, which was not using the full 14 bits
3947 of clock sequence when generating UUID's.
3949 Fix a Y8.8888K problem in the uuid library.
3951 Logsave now creates a new session id for itself to avoid getting
3952 killed by init whan transitioning between init levels.
3954 Change the licensing of the UUID library to be the 3-clause BSD-style
3955 license; this allows Apple to use the uuid library in Darwin.
3957 Add ocfs and ocfs2 probe support into the blkid library.
3959 Fix a memory and file descriptor leak in the blkid library.
3961 The blkid library will revalidate the device if the system time is
3962 earlier than last verification time of the device, since that
3963 indicates that the system time is probably nottrustworthy.
3965 The blkid library will override the default location of the blkid.tab
3966 file by the BLKID_FILE environment variable, if it is available.
3968 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3970 Add various portability fixes for lame new versions of glibc, Darwin
3971 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3972 Bugs #239934, #264630, #269044, #255589, #289133)
3974 Add support for Windows 9x/NT under Cygwin.
3976 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3977 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3979 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3981 Update the rpm spec files so that it works better with Fedora core 2
3984 Fixed various Debian packaging issues (see debian/changelog). In
3985 particular, fixed the Debian initrd scripts. (#241183, #248050,
3992 Fixed various gcc -Wall warnings.
3994 The uuid library now has new functions uuid_unparse_upper() and
3995 uuid_unparse_lower() which forces the case of the hex digits to be
3996 upper case, or lower case.
3998 The build process has been speeded up by enhancing the subst program
3999 to update the modtime on the generated files even when the generated
4000 file hasn't changed.
4002 The uuid library now uses C99 stdint.h types instead of custom types.
4004 Updated config.guess and config.sub with newer versions from the FSF.
4006 Removed out of date .cvsignore files from the source distribution.
4008 The ext2fs_unlink() function will return an error if both the name and
4009 inode number are unspecified, to avoid doing something surprising
4010 (such as unconditionally deleting the first directory entry).
4011 Directory entries are now deleted by coalescing them with the previous
4012 directory entry if possible, to avoid directory fragmentation. This
4013 is not an issue with the e2fsprogs suite, but may be a problem for
4014 some of the users of libext2fs, such as e2tools.
4016 Add support for version numbers of the form "1.36-rc1".
4018 Fix build of mke2fs.static.
4020 Add basic ext2fs library support for large (EA in inode) inodes.
4022 The test_io mechanism can now abort after n reads or writes to a
4023 particular block. The block is specified by TEST_IO_BLOCK environment
4024 variable, and the read/write count by the TEST_IO_READ_ABORT and
4025 TEST_IO_WRITE_ABORT environment variables. The block data is now only
4026 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4028 UUID_DEFINE() in the uuid library now creates a static variable, with
4029 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4030 be used in header files.
4032 Add support for the install-strip and install-shlibs-strip targets, as
4033 suggested by the GNU coding guielines. "make install" no longer
4034 strips the binaries which are installed.
4036 Remove support for the --enable-old-bitops configure option which was
4037 only for very old sparc systems.
4039 Remove support for --enable-clear-htree; this was only needed during
4040 the early development of the htree patch.
4042 Use Linux-kernel-style makefile output so it is easier to see compiler
4045 Update gettext files to version 0.14.1.
4047 Update to use autoconf 2.5x.
4049 Improved support for compiling e2fsprogs under dietlibc.
4051 Make e2fsprogs portable to Solaris and FreeBSD systems.
4053 Add blkid_verify(), blkid_get_library_version(), and
4054 blkid_parse_version_string() functions to the blkid library.
4056 Add pkg-config files for e2fsprogs's libraries.
4058 Fix "make uninstall" to so that it removes everything that is installed.
4060 Add a configure --enable-maintainer-mode option which enables the
4061 makefile rules to rebuild the configure script from configure.in, and
4062 to reubuild the .gmo files in po directory.
4064 Drop the sparc assembly bitwise operations; it's less efficient
4065 than the GCC 3.4 compile code and triggers compiler warnings on
4066 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

4070 E2fsprogs 1.35 (February 28, 2004)
4071 ==================================
4073 E2fsck has a new -k option, which in conjunction with the -c options,
4074 preserves the existing badblocks list.
4076 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
4078 E2fsprogs will now deal correctly with symlinks that contain
4079 extended attribute information, which can be created using SE Linux.
4080 (Addresses Debian Bug #232328)
4082 Remove a double longjump into an invalid stack frame bug in e2fsck.
4083 (This was during an abort sequence, which normally worked on Linux and
4084 caused a core dump on other operating systems.)
4086 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
4087 (the NLS library will replace "" with the .po header information).
4089 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4090 dump due to a division by zero error. (Addresses Debian bug #207082)
4092 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4093 when reconnecting a directory requires creating a lost+found
4094 directory. (Addresses Debian bug #219640).
4096 Fixed a bug where e2fsck would bomb out if a journal needed to be
4097 replayed when using an alternate superblock.
4099 E2fsck will give an extra grace period before actually forcing a check
4100 if the laptop is running on battery. The next time fsck runs while
4101 the system is on the AC mains, or after the grace period is exceeded,
4102 the filesystem will be checked. (Addresses Debian bug #205177)
4104 E2fsck will inform the user when there are 5 or fewer mounts before a
4105 filesystem check will be forced. (Addresses Debian bug #157194)
4107 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4108 We now correctly handle the case where there is an overlap between a
4109 block group descriptor or a superblock and a bad block indirect block.
4110 In the case where the indirect block is corrupted, we now suggest
4113 Fix byte swap bugs in e2fsck that caused the journal backup location
4114 in the superblock and symlinks created by SE Linux to be cleared
4115 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
4117 E2fsck -c now replaces the current list of bad blocks with the ones
4120 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4121 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4123 Fix a potential bug in e2fsck which could cause it to core dump when
4124 trying to print the location of the backup superblock.
4126 Protect against a potential core dump in e2fsck when printing a
4127 message about backup superblocks.
4129 Add support for backing up the journal inode location in the
4130 superblock. E2fsck will automatically save the journal information in
4131 the superblock if it is not there already, and will use it if the
4132 journal inode appears to be corrupted. ext2fs_add_journal_inode()
4133 will also save the backup information, so that new filesystems created
4134 by mke2fs and filesystems that have journals added via tune2fs will
4135 also have journal location written to the superblock as well.
4136 Debugfs's logdump command has been enhanced so that it can use the
4137 journal information in the superblock.
4139 E2fsck will now update all superblocks when moving the journal inode.
4141 Shrink the size of the e2fsck executable by moving some initialized
4142 variables to the BSS segment.
4144 E2fsck will avoid printing the ^A and ^B characters which bracket the
4145 progress bar when stdout and stdin are a tty device instead of a pipe
4146 to another program. (Addresses Debian bug #204137)
4148 Debugfs's mkdir command will automatically expand the directory if
4149 necessary. (Addresses Debian Bug: #217892)
4151 Fixed a bug in debugfs so that copying a file from /dev/null uses the
4152 correct mode bits. (Addresses Debian Bug: #217456)
4154 If the environment variables DEBUFS_PAGER and PAGER are not set,
4155 debugfs now searches for the appropriate pager to use, beginning with
4156 /usr/bin/pager, and then falling back to 'more' and 'less'.
4157 (Addresses Debian bug #221977)
4159 Debugfs will now support 2.6 device numbers where the major or minor
4160 number may be larger than 255. (Addresses Sourceforge bug #865289)
4162 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
4164 Chattr now stops processing options when it sees '--'. (Addresses
4167 Fix regression tests so they work correctly when e2fsprogs is compiled
4168 with configure --disable-htree.
4170 Fix bug in uuid library when there is no network card and the library
4171 is generating a time-based uuid. The random MAC address was not
4172 correctly generated to be a multicast address.
4174 Add compile_et extensions from Heimdall that were missed the first time
4177 Fix bug in badblocks when using O_DIRECT; we need to make sure that
4178 we're reading from an offset which is page aligned. For read-only and
4179 read-write tests, we try to recover after an error so that we can
4180 continue reading on page-aligned boundaries. (Addresses Debian Bug
4183 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
4186 Updated and clarified various man pages. (Addresses Debian Bug
4187 #206845, #222606, #214920, #232406)
4189 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
4191 Fixed various Debian packaging issues (see debian/changelog).
4196 Fixed a build problem so that e2fsprogs would compile with the
4197 --enable-profile option to configure selected. (Addresses Sourceforge
4200 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
4201 Bugzilla Bug #112448)
4203 Centralize code which calculates the location of the superblock
4204 and block group descriptors so that it is in a single library routine.
4206 Added two new functions, ext2fs_file_open2() and
4207 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4209 Fix compile_et to output the correct prototype for
4210 initialize_xxx_err_table_r() in the header file. (Addresses Debian
4213 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4215 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4216 present. This is for when we try stuffing an int into void * pointer.
4218 Fix type-punning which can cause gcc 3.x to miscompile code by getting
4219 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
4220 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4221 **'. The EVMS code uses an ugly union approach since we don't want to
4222 modify the EVMS interfaces.
4224 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4225 aid build process on systems can use invoke GNU make as "gmake".
4227 Added regression testing for mke2fs.
4229 Fixed gcc -Wall nitpicks.
4231 Fixed various compiler warnings.
4233 Add portability fixes for FreeBSD and for using fsctl under Darwin to
4234 support ext2 ioctl's.
4237 E2fsprogs 1.34 (July 25, 2003)
4238 ===============================
4240 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4241 a tight loop while waiting for a child fsck to exit in some cases.
4242 This burns CPU times which slows down the low-level filesystem check.
4244 Added code to mke2fs to assure that the default block size for a
4245 filesystem is at least as big as the sector size of the device, if it
4248 Changed mke2fs and resize2fs to round the default size of a filesystem
4249 to be an even multiple of the VM pagesize in order to avoid a Linux
4250 kernel bug introduced when the storage of the buffer cache was moved
4251 into the page cache.
4253 Mke2fs will warn the user when creating a filesystem with journaling
4254 and a blocksize greater than 4096. (Addresses Debian bug #193773)
4256 Fixed a bug in resize2fs which caused it to fail on filesystems with a
4257 non-empty bad block list. Resize2fs now discards any blocks on the
4258 badblock list which are no longer part of the filesystem as the result
4259 of a filesystem shrink. (Note: this means that shrinking and then
4260 enlarging a filesystem is no longer a reversible operation;
4261 information about bad blocks in the part of the filesystem which is to
4262 be chopped off will be lost.)
4264 Changed resize2fs so the user can use prefixes to specify the units of
4265 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4266 and to make the error and informational messages explicitly display
4267 the blocksize used by the filesystem, in order to avoid confusion.
4268 (Addresses Debian bug: #189814)
4270 Added a new debugfs command, dump_unused, which dumps the contents of
4271 all unused blocks to stdout. (Useful as an emergency try-to-find
4272 deleted data command.)
4274 Added a new debugfs command, imap, which prints the location of a
4275 specified inode in the inode table.
4277 Fixed a bug in the badblocks program which caused it to use one bit of
4278 randomness in its non-destructive read/write test, instead of using a
4279 full 8 bits of randomness.
4281 Added a new option (-t) to badblocks, which allows the user to control
4282 the test pattern(s) used when checking a disk.
4284 The blkid probe function now more correctly detects UDF filesystems.
4286 Fixed a bug in the blkid library which caused it to not update its
4287 cache if a filesystem changes from having a label to not having a
4290 Fixed a bug in the blkid library wihch could avoid an infinite loop
4291 in blkid_find_dev_with_tag() if /proc is not mounted and there the
4292 /etc/blkid.tab file has not yet been created.
4294 Fixed the badblocks program so that the destructive read/write test
4295 honors the -c option, and to use O_DIRECT when possible to avoid
4296 thrashing the system block buffer cache.
4298 Fixed various NLS issues.
4299 - Added Czech and Swedish translations
4300 - Removed testing NYC translation
4301 - Fixed NLS support for message abbrevations in e2fsck
4302 - Remove de-utf.po, since we shouldn't have two versions using different
4304 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
4305 simplify the statistics reporting in e2fsck.
4307 Changed configure.in so that its defaults for *BSD systems no longer
4308 build an fsck wrapper, and not to install in /usr/local by default.
4310 Fixed some minor spelling errors/typo's in e2fsck and the configure
4313 Fixed various Debian packaging issues (see debian/changelog).
4315 Updated and clarified man pages. (Addresses Debian Bug #195616)
4320 Fix gcc -Wall nitpicks.
4322 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4323 NLS support by default. (Added partial workaround for gettext/Darwin
4324 incompatibility problems.)
4326 Added full MIT KRB5 and Himdall compaibility support to the com_err
4327 library and the compile_et program. (Addresses Debian bug #191900)
4329 Added the blkid_known_fstype() function to the blkid library, which
4330 returns true if it is passed a filesystem type which is recognized by
4331 the blkid probing functions.
4333 Improved the documentation for the blkid library.
4335 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4336 returns the hardware sector size of a device, if it is available.
4338 Added a dependency in the blkid library's .so file to the uuid
4339 library, since the former uses the latter. (Addresses Debian bug
4342 Added --with-diet-libc and --disable-evms to the configure script.
4344 Fixed a minor memory leak in the badblocks program.
4346 Fixed a portability problem in tune2fs --- not all systems have strptime().
4348 Fixed a portability problem in debugfs with the use of getopt() more
4349 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
4352 Add support Windows support to ext2fs_get_device_size().
4354 Added (normally disabled) debugging code to the Unix I/O manager which
4355 causes it to disable all userspace caching if the NO_IO_CACHE is
4358 Changed the test I/O manager so it can always be linked into e2fsck,
4359 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4360 configure script. The test I/O manager will only print any debugging
4361 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4362 variables are set, which specifies which I/O operations are logged and
4363 a block number to watch, respectively. The log messages are sent to
4364 stderr by default, unless a filename is specified via the
4365 TEST_IO_LOGFILE environment variable.
4368 E2fsprogs 1.33 (April 21, 2003)
4369 ===============================
4371 Added a new utility program, logsave, which captures the output of a
4372 command in a log file, even if the containing directory hasn't been
4373 mounted yet (in which case the it saves the output in memory until it
4374 can write out the logfile). This is useful for capturing the
4375 output of fsck during the boot sequence.
4377 Fixed some portability problems that were causing problems under
4378 the Cygwin32 environment.
4380 Mke2fs now interprets a negative number to the -b option as a minimum
4383 Fixed a bug in mke2fs which was incorrectly checking the argument to
4384 the -g option if the default block size was used. (Addresses Debian
4387 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4388 it can not find filesystem checkers for jfs, reseirfs, and xfs.
4390 E2fsck now updates the global free block and inode counters from the
4391 block group specific counters quietly. This is needed for an
4392 experimental patch which eliminates locking the entire filesystem when
4393 allocating blocks or inodes; if the filesystem is not unmounted
4394 cleanly, the global counts may not be accurate.
4396 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4397 2.0 is not yet supported; this only pulled in the bug fixes: fixed
4398 possible hangs caused by bugs in calling waitpid, and not setting the
4399 pipe to non-blocking mode; also fixed a file descriptor leak; made
4400 sure all functions call log entry/exit functions.)
4402 Badblocks now flushes its output file as bad blocks are discovered.
4404 The uuid library is now more paranoid about assuming the correctness
4405 of the /dev/random device; it mixes in a stream of bytes from
4406 random/srandom, just in case.
4408 Update Debian files to reflect the fact that I am now the Debian
4409 maintainer of e2fsprogs. Other various Debian-specific packaging
4412 Move the source tarball generation functions from the top-level
4413 makefile to the util/gen-tarball script.
4415 Updated the Turkish .po translation file.
4417 Added Heimdal and MIT krb5 extensions to the com_err library to make
4418 it more compatible with com_err libraries from those distributions.
4420 Changed dumpe2fs to always display the superblock fields relating to
4421 the journalling and/or directory indexing feature even if those
4422 features are not enabled.
4424 Updated and clarify copyright statement vis-a-vis alpha releases of
4427 The ss library will now try to dynamically link to the readline
4428 library and use it if it is present in the system. This means that
4429 the debugfs program now has line editing and history features. The
4430 SS_READLINE_PATH environment variable is used to find a readline or
4431 readline-compatible library.
4433 E2fsck now finds most duplicate filenames (all when rebuilding all
4434 directories via the -D option) and offers to delete or rename
4435 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
4437 Fix bug in e2image. When writing out a raw image file, include data
4438 blocks from symlinks that do not store the symlink within the inode.
4440 Fix bug in resize2fs which incorrectly moved the block and inode
4441 bitmaps for sparse superblock filesystems and incorrectly marked
4442 blocks as in use. (Addresses Debian bug #174766)
4444 Added a new shared library, the blkid library, which efficiently
4445 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4446 and UUID filesystem specifiers without needing to search all of the
4447 devices in the system. Instead, the device is looked up in a cache
4448 file, and then verified to make sure the blkid cache is correct.
4450 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4451 the device name, using the blkid library. (Addresses Debian bugs
4454 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4455 used for spaces in device labels.
4457 Removed 32-bit limitations for debugfs's dump command.
4459 If the user specifies a large number of inodes, Mke2fs will
4460 automatically adjust the number of blocks per group to find a valid
4461 set of filesystem parameters.
4463 Add workaround to detect broken MD devices where when some of the
4464 underlying devices are marked read-only, writes to the MD device are
4465 silently dropped. E2fsck will detect if there is an attempt to run
4466 the journal twice, and abort with an error if this is the case.
4467 (Addresses IBM Bugzilla bug #1226)
4469 E2fsck will print an error if more than one of the -p/-a, -n or -y
4470 options are specified.
4472 E2fsck will fix HTREE corruptions in preen mode, without stopping the
4473 boot process. This is needed because the 2.4 ext2 filesystem
4474 accidentally had the INDEX_FL backwards compatibility code removed.
4476 Mke2fs no longer creates filesystems with the dir_index flag set by
4477 default; the user has to specifically request it.
4479 Update and clarified various man pages. (Addresses Debian bugs
4480 #173612, #175233, #175113, and #170497, #185945, #188318)
4482 Created man page for the mk_cmds program (from the libss library).
4487 Fix various gcc -Wall nits.
4489 Fixed a lot of portability problems that caused e2fsprogs not to build
4490 successfully under Solaris and Apple/Darwin.
4492 Fixed a Makefile dependency to allow building e2fsprogs using parallel
4495 Changes to create a subset distribution which consists only of the
4496 et, ss, uuid, and blkid libraries. The configure script and top-level
4497 makefile were changed to support working with a subset distribution.
4499 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4500 actually used, and might people who are looking for
4501 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4503 Updated debian files to fix a number of Lintian warnings.
4505 Updated config.guess and config.sub with newer versions from the FSF.
4507 Removed unnecessary libraries from being linked into the fsck, lsattr,
4508 chattr, and blkid executables.
4510 E2fsprogs 1.32 (Nomvember 9, 2002)
4511 ==================================
4513 Fixed a bug in the Unix I/O routines which caused needless writebacks
4514 of clean blocks from the unix_io cache (they were erroneously marked
4515 as being dirty, so they were getting written back to disk before
4516 getting evicted from the disk cache). This was harmless, but it
4517 significantly slowed down e2fsck.
4519 Made some other minor optimizations to the Unix I/O routines to save a
4520 small amount of CPU time.
4522 Updated internationalization files.
4525 E2fsprogs 1.31 (Nomvember 8, 2002)
4526 ==================================
4528 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
4529 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
4530 handling for child process that die unexpectly. Add a hack to force
4531 mkfs to create filesystems that won't cause problems with hardware
4532 that has 2k or 4k minimum blocksize requirements. Read from child
4533 processes in non-blocking mode, so that the GUI continues to update.
4535 Fix e2fsck so that it returns the appropriate exit code when the root
4536 filesystem has been changed, so that system's rc scripts will be told that
4537 the system needs to be rebooted.
4539 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4540 was set, some of the descriptor blocks that should have been written
4541 out were getting skipped.
4543 Changed e2fsck to force out changes to the backup copies of the
4544 superblock and block group descriptors when important changes are made
4545 to those data structures.
4547 Fix a bug where e2fsck could erroneously mark a filesystem as being
4548 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
4549 introduced in e2fsprogs 1.28.)
4551 If journal debuging is enabled using --enable-jbd-debug, the debugging
4552 level is now set via the E2FSCK_JBD_DEBUG environment variable.
4554 If byteswapping support is disabled using configure --disable-swapfs,
4555 skip the tests which depend on byte-swapping, so that "make check"
4558 Lshattr will now display the indexed directory flag. Also, some of
4559 the more esoteric compression flags are supressed unless compression
4560 support has been enabled.
4565 E2fsprogs 1.30 (October 31, 2002)
4566 =================================
4568 When resizing a filesystem, and inodes need to moved, resize2fs will
4569 update the inode's ctime field, and the mtime field of the containing
4570 directories, so that incremental backups using dump/restore will work
4573 In order to avoid spurious errors, e2fsck wil check the last
4574 superblock write time to determine whether or not it can safely use
4575 the LOW_DTIME checks to determine if there are inodes on the orphan
4576 inode linked list that had somehow gotten disconnected. (Addresses
4577 Sourceforge bug #620980)
4579 Partition in /proc/partitions that being with the string "lvm" are
4580 considered real partitions even if they do not end with a number.
4582 Fixed a bug in the the uuid generation function, where if /dev/urandom
4583 is not present, but /dev/random is, and there isn't sufficient
4584 entropy, the get_random_byte function could spin a loop forever.
4586 E2fsck, mke2fs, etc. will now reliably notice when image files are
4587 mounted using the loopback interface. (Addresses Sourceforge bug
4590 When flushing buffers (as is done by badblocks, for example) check to
4591 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4592 FDFLUSH ioctl which causes the MD device driver which causes confusing
4593 syslog messages about obselete ioctl messages. (Addresses Sourceforge
4596 Debugfs's write command now checks to see if the destination filename
4597 exists before creating it. (Addresses Sourceforge bug #478195.)
4599 When installing man pages, search for compressed man pages using all
4600 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4602 Fixed a bug in fsck where multiple filesystems specified on the
4603 command were not being checked in parallel due to a logic bug
4604 introduced to support the FSCK_MAX_INST environment variable.
4606 We have added a new superblock field, s_mkfs_time, which indicates
4607 when a filesystem was created. It is set via mke2fs, and printed out
4608 by dumpe2fs, but is not actually touched by the kernel.
4610 Dumpe2fs has been made more robust by not aborting if there is an
4611 error reading the block/inode bitmaps; instead it will still print out
4612 the location of the block/inode bitmaps and inode table.
4614 Add support for the an alternative block group descriptor layout which
4615 allows for on-line resizing without needing to prepare the filesystem
4616 in advance. (This is the incomat feature flag meta_bg.)
4618 Add support for storing default mount options in the superblock, so
4619 that the filesystem can be mounted with specific mount options without
4620 needing to specify them on the mount command line or in the /etc/fstab
4623 Add support for a new inode flag, which is to be used for indicating
4624 the top of directory hierarchies for the Orlov block allocator.
4626 Fix e2fsck so that if it creates the lost+found directory, it does so
4627 with the more apporpriate permissions of 0700. Also change
4628 mklost+found so that it also creates the directory 0700.
4630 Fixed format bug in e2fsck if NLS is in use.
4632 Add a German translation for e2fsprogs's NLS support.
4634 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4635 the beginning of the inode table. This won't matter much, since if
4636 there is a bad block at the beginning of the inode table, the root
4637 directory won't be available. But at least e2fsck won't crash in this
4640 Fixed endian problems in the htree code for e2fsck and debugfs.
4642 When byte-swapping a filesystem on a PPC architecture, byte-swap the
4643 bitmaps since the historical big-endian ext2 variant had byte-swapped
4644 bitmaps, and the ext2fs library assumes this. This fixes the
4645 regression test suite on PPC machines.
4647 Fix e2image so that it handles a bad block in the inode table
4650 E2fsck now uses a more sophisticated algorithm to salvage corrupted
4651 directories that recovers more information in the corrupted directory
4654 E2fsck now performs additional consistency checks on indexed (HTREE)
4657 Fix bug where efsck might get confused about whether a completely
4658 empty directory block is an empty leaf block or an interior htree
4659 node. This could cause e2fsck to get confused into think that a valid
4660 indexed directory was corrupted.
4662 E2fsck no longer creates an empty directory entry at the end of a
4663 directory block when optimizing a directory. This would cause some
4664 earlier versions of the dxdir kernel code to corrupt the directory
4665 when attempting to split a node containing an empty directory entry.
4667 E2fsck could sometimes in rare circumstances leave the indexed flag
4668 set after a small directory was optimized by compressing it instead of
4669 indexing it. (This should never happen in real life, since
4670 directories that small wouldn't have been indexed, but better safe
4673 E2fsck now only updates the master superblock in all cases. This
4674 slightly shortens its run time.
4676 Ext2ed can deal with directory entries of length 0; previously it
4677 would get stuck in an infinite loop.
4679 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4680 specifiers. (Sourceforge patch #613447)
4682 Badblocks will now work correctly on read-only devices such as
4683 CD-ROM's. (Sourceforge patch #600451)
4685 Updated and clarified man pages. (Addresses Debian bug #167108)
4688 E2fsprogs 1.29 (September 24, 2002)
4689 ===================================
4691 Fixed a bug in e2fsck which could corrupt a directory when optimizing
4692 it (via the -D option) or rebuiliding the hash tree index with a 1 in
4693 512 probability, due to a fence post error.
4695 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4698 Mke2fs now enables the directory indexing flag by default. (Since
4699 this is a compatible feature flag, it's safe to do so.)
4701 Tune2fs will support setting the directory indexing feature flag. It
4702 will automatically set up the default hash algorithm and hash seed
4703 fields in the superblock.
4705 If the bone-headed user enters the root filesystem twice in
4706 /etc/fstab, the -R option which skips the root filesystem will skip
4707 all of them. (Addresses Debian bug #159423). Note! This is not a
4708 precedent for dealing intelligently with any other kind of doubled
4709 entry in /etc/fstab!
4715 Removed perror declaration in lib/et/internal.h. All modern systems
4716 can be expected to define perror() these days. Besides, the lib/et
4717 code wasn't using perror at all anyway. :-)
4720 E2fsprogs 1.28 (August 31, 2002)
4721 ================================
4723 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4724 for setting the htree flag is not included yet, although it can be
4725 manually turned on via the debugfs program.
4727 Clarified e2fsck error message which is printed when it cannot find
4728 sufficient contiguous block when relcating filesystem metadata.
4730 Added support for building an EVMS plugin module for ext2/3. This
4731 module is substantially the same as the EVMS module shipping with EVMS
4732 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4733 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4734 if the configure --enable-old-evms flag is given.
4736 Fsck will search through EVMS volumes when trying to resolve
4737 filesystem specifications such as LABEL=xxx or UUID=xxx.
4739 Added a new utility program, /sbin/findfs, which will return
4740 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4743 Update and clarified various man pages. (addresses Debian Bug #145044,
4744 #146437, #131350, #151990, #144621, #141938)
4746 If there are no filesystems specified on fsck's command line, fsck now
4747 treat that as if the -As options were given. Previously it would
4748 simply do nothing. (Addresses Debian Bug #153102)
4750 Mke2fs no longer treats a failure to be able to clear the MD signature
4751 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4754 The e2p library functions (which are used by lsattr and chattr) now
4755 double check to make sure the file is a regular file or directory
4756 before attempting to use the ext2 ioctls. Some device drivers
4757 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4758 (Addresses Debian Bug #152029).
4760 The extended attribute handling has been updated to correspond with
4761 the latest V2 bestbits ACL code.
4763 Fixed bug in e2fsck which caused it to not clear the dtime field when
4764 processing truncated inodes on the orphan list. This could cause data
4765 loss(!) if a filesystem is rebooted before a truncate has been
4768 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4769 algorithms. This makes e2fsck much faster in the case of severely
4770 corrupted filesystems where a large number of blocks are claimed by a
4771 large number of inodes. (Thanks to the 2.5 IDE device driver for
4772 inspiring this work.)
4774 Resize2fs has been significantly sped up when shrinking and expanding
4775 a filesystem by a very small number of blocks (for example, when EVMS
4776 is converting a partition to be an EVMS legacy volume).
4778 Added a new option to e2fsck, -D, which will optimize or compress all
4779 of the directories in the filesystem.
4781 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4782 properly clean up and only exit at safe points. Fsck will pass
4783 SIGINT/SIGTERM to its child processes, and wait until they have all
4784 exited before it exits.
4786 The uuid parsing code in the uuid library now properly complains when
4787 an illegally formated uuid is presented to it. (Addresses Debian bug
4790 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4791 and 2.4.17, since the workaround can cause problems when using a 2.4
4792 kernel with an old version of glibc built with the 2.2 headers.
4794 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4795 superblock used by other filesystems. (Addresses Debian bug #147256.)
4797 Added support for the synchronous directory feature written by Andrew
4800 The debugfs program can delete directories using the rmdir command.
4802 Add support for 8k and 16k filesystems (for systems with page sizes
4803 that are greater or equal to 8k or 16k, respectively). Note that
4804 these filesystems can not be mounted on x86 systems, or other systems
4805 with only 4k page sizes, due to limitations in the current Linux VM
4808 Resize2fs requires that the filesystem state be valid and have no
4809 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4810 required that the last fsck time be greater than the last mount time.)
4812 Configure now defaults the man pages directory to /usr/share/man on
4815 E2fsck now offers to truncate inodes which contain too many blocks (so
4816 that i_blocks would overflow. Also fixed handling of large sparse
4819 E2fsck now more completely checks for symlink validity, including
4820 requiring NULL termination and length checks.
4822 E2fsck will offer to try forcing a disk write to remap a bad block
4823 after finding a read error when reading a filesystem metadata block.
4825 Fixed a bug in debugfs which caused the -b and -s options to crash
4826 debugfs, as well as breaking the testb, setb, and clearb functions.
4828 Added a bmap command to debugfs which calculates the logical to
4829 physical block mapping for a particular inode.
4831 Fixed a bug in code which checked to see if a device was mounted which
4832 sometimes (rarely) failed in the case of a plain file.
4834 Fixed a bug in resize2fs where when it reported an error, it would
4835 print a message erroneously indicating that the filesystem had been
4836 resized before it aborted.
4838 When resizing a plain file which is smaller than the requested size,
4839 resize2fs will attempt to extended the file so that programs like
4840 e2fsck will not complain that the file is too small.
4842 Resize2fs will print the actual new size of the filesystem when it is
4845 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4846 information on big-endian systems.
4852 Fixed collisions with C++ reserved words.
4854 Added portability fixes for building e2fsprogs on the HURD and AIX.
4856 Added the ext2ed program for creation of test cases. (ext2ed has many
4857 limitations and bugs which make it unsuitable for production use.)
4859 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4860 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4861 name_len field is byte swampped on big-endian machines, since in the
4862 V2 structure, name_len is a char field which is doesn't need to be
4863 byte swapped --- except if an old-style kernel had byte-swapped the
4864 name_len field as part of the V1 structure.
4867 E2fsprogs 1.27 (March 8, 2002)
4868 ==============================
4870 The warning messages for mke2fs now go to standard error.
4872 Fixed to make sure "make check" runs all of the test programs with
4873 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4875 The mke2fs program checks the boot sector for the BSD disk label, and
4876 avoids erasing it if it is there.
4878 Fixed a bug in e2fsck which caused it to core dump if the journal
4879 inode was missing when it was supposed to be there.
4881 E2fsck now prints ranges in pass 5 when printing deltas for the block
4884 Debugfs's "ls -l" command now will print out the file type information
4885 in the directory entry.
4887 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4888 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4890 Debugfs can now examine the experimental directory indexing
4893 Fixed bug in debugfs which caused it to core dump if modify_inode is
4894 called without an open filesystem.
4896 The debugfs lsdel command now runs its output through a pager first.
4898 When installing manual pages, remove the compressed manual pages first.
4900 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4902 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4903 actually broke things on mips32, sparc32, and Alpha platforms.
4905 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4906 (which is required by the newer libintl libraries).
4911 Fixed various gcc -Wall complaints.
4913 Fixed a few memory leaks in the e2fsck journaling code, and in the
4914 ismounted code checking for a swap device.
4916 Add new inode I/O abstraction interface which exports an inode as
4919 Exported ext2_file_flush as a public interface.
4921 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4923 Lots of small random portability fixes to make e2fsprogs build under
4924 AIX --- even without the 5L compatibility toolkit, and even using the
4925 uber-crippled AIX native C compiler.
4928 E2fsprogs 1.26 (February 3, 2002)
4929 =================================
4931 Dumpe2fs will keep going now if the bad block inode can't be read.
4932 (Previously it stopped with a fatal error.)
4934 E2fsck will now give an opportunity to run the journal even if the
4935 recovery flag is not set. This is the default behaviour if e2fsck is
4936 using a backup superblock, since the needs_recovery flag will never be
4937 set in the backup superblock copies.
4939 E2fsck now automatically finds the backup superblock/group descriptors
4940 even when the primary superblock is completely destroyed for 2k and 4k
4941 filesystems. (Previously it just guessed/assumed that we were dealing
4942 with a 1k filesystem in that case, and users had to manually specify
4943 the backup superblock number.)
4945 Fixed a bug in e2fsck where it dereferences a null pointer when there
4946 is a problem opening a filesystem in preen mode.
4948 E2fsck now handles external journals correctly; previously it trashed
4949 the external journal device if the journal needed to be replayed.
4951 Work around ulimit incompatibility problem caused by recent 2.4
4952 kernels; the unix IO module will automatically try to set any resource
4953 limits to be infinite on startup.
4955 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4956 bitmap if it wasn't present and the blocksize was 2k or 4k.
4957 (Addresses Debian Bug #116975)
4959 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4960 clearing the new V2 fields if they do not make sense or if the ext3
4961 superblock is version 1 superblock.
4963 E2fsck will automatically relocate the ext3 journal from a visible
4964 file (i.e., /.journal) to an hidden inode if the filesystem has been
4965 opened read/write. This allows the users to add a journal while the
4966 filesystem is mounted, but the next time the system is rebooted, the
4967 journal file will disappear. This avoids problems with backups,
4968 stupid operators with superuser bits, etc.
4970 Fix a bug in fsck where it would not support a filesystem type of
4971 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4973 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4974 automatically identify reiserfs filesystems.
4976 The number of processes spawned by fsck can now be limited using the
4977 FSCK_MAX_INST environment variable.
4979 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4980 should be searched for UUID and label information.
4982 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4983 limit if at all possible, when opening a block device. (The filesize
4984 limit shouldn't be applied against writes to a block device.)
4986 In mke2fs and e2fsck, specifying the -c option twice will now do
4987 a read/write test on the disk. Update the man pages to encourage
4988 using the -c option, and to discouraging running badblocks separately,
4989 since users tend to forget to set the blocksize when running
4992 Mke2fs now automatically clears the immutable attribute on a
4993 pre-existing .journal file left over from a previous failed attempt to
4994 add a journal to an alreadyy-mounted filesystem.
4996 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4999 Mke2fs now creates the lost+found directory with permissions of 0700,
5000 so that files that had previously lived in protected directory are
5001 safe if they get dropped in lost+found and the system administrator
5002 doesn't deal with immediately. (Addresses Debian #bug 118443)
5004 Mke2fs and e2fsck (and all programs that use the
5005 ext2fs_check_if_mounted function) will now properly identify that a
5006 device is mounted, even in cases where devfs has confused things with
5007 multiple devices names with the same identity, or if a dim-witted
5008 system administrator has done something stupid like creating device
5009 file aliases in their home directory. Also now checks for swap devices
5010 by using /proc/swaps. (Addresses Debian bug #106622)
5012 Added a new option (-T) to tune2fs which sets the time a filesystem
5015 Speed up e2image when creating sparse raw image files by optimizing
5016 away excess lseek() system calls.
5018 Fix support of large (> 2GB) files when used as a filesystem in
5019 mke2fs, tune2fs, debugfs, and findsuper.
5021 Debugfs's stat and icheck commands now properly deals with large (>
5024 Debugfs's set_super_value command now prints out the list of valid
5025 superblock fields which can be set using the command.
5027 Debugfs's rm and kill_file command now updates the superblock free block
5028 and inode counts, thus keeping the filesystem consistent.
5030 Debugfs's lsdel command now takes an optional argument which allows
5031 the user to only see the most recently deleted files.
5033 A new command (undel) was added to debugfs which automates
5034 undeleting a deleted inode and linking it back to a directory.
5036 Debugfs's ls command now takes a new option, -d, which lists
5037 deleted directory entries.
5039 Debugfs's testb, freeb, setb, and find_free_block commands now take an
5040 optional count argument.
5042 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5043 be used to signal that a particular inode should not be eligible for
5044 tail-merging --- this is needed for programs like LILO.
5046 The findsuper (an unreleased, uninstalled utility program) has been
5047 improved to add extra validity checks and to add a progress meter.
5048 (It is still an unsupported program; the officially supported way to
5049 recover from a trashed partition table is to use gpart; findsuper is
5050 for wizards only. :-)
5052 Debugfs was fixed to compile with "configure --disable-swapfs".
5054 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
5056 Added new translation file for Turkish.
5061 Fix general gcc -Wall complaints.
5063 E2fsprogs (mostly) works with the dietlibc.
5065 The programming texinfo file has been expanded to include description
5066 of additional libext2fs functions. (Still not compeltely done, but a
5067 lot of the more important functions have been documented.)
5069 Added a umask structure to struct_ext2_filsys, which currently only
5070 modifies the behaviour of ext2fs_mkdir(), but if we add any file
5071 creation functions to libext2fs, we should also make sure they respect
5074 The build-rpm script was fixed to be a bit more safe.
5076 The tests' Makefile now has a way of automating test case creation
5077 for e2fsck, using "make testnew".
5079 Created a new function, ext2fs_dir_iterate2 which passes more
5080 information to the callback function (identical to the one used by
5081 ext2fs_dblist_dir_iterate). The directory iterator functions take a
5082 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5083 directory entries. If the directory entry is deleted, the callback
5084 function will be called with the entry paraemter set to
5085 DIRENT_DELETED_FILE.
5087 Added new functions, ext2fs_inode_alloc_stats and
5088 ext2fs_block_alloc_stats, which takes updates block/inode allocation
5089 statistics in the bitmaps, block group descriptors, and superblock
5090 when inodes or blocks are allocated or deallocated.
5093 E2fsprogs 1.25 (September 20, 2001)
5094 ===================================
5096 This is primarily a bug-fix release; no new features were added, but
5097 there are a number of embarassing bug fixes and cleanups applied.
5099 Fix a bug mke2fs which causes stack garbage to be written to disk when
5100 zapping disk sectors. (This bug could cause mke2fs to core dump for
5101 some kernels, I suspect with security enhancement patches.)
5103 Remove unneeded #include of <linux/config.h> which was breaking
5104 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
5106 Updated tune2fs man page to reflect the fact that adding or removing a
5107 journal doesn't require running e2fsck.
5109 Remove use of AC_REQUIRE from autoconf which had been used to prevent
5110 AC_CANONICAL_HOST from being called twice; unfortunately this causes
5111 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5112 used outside of autoconf macros. Fortunately, it doesn't seem to be
5113 necessary any more, anyway.
5115 E2fsck will now not fall back to an alternate superblock if the user
5116 specifies the superblock location explicitly on the command-line.
5117 This allows easier recovery from a situation where the primary
5118 superblock and block groups are slightly corrupted, but the backup
5119 superblocks are completely broken.
5121 Fix problem which caused compile_et and mk_cmds to blow up if
5122 e2fsprogs was in a directory with a pathname that contained spaces.
5124 We are now more paranoid about checking the entry in /etc/mtab to make
5125 sure the filesystem is really mounted, since some broken distributions
5126 (read: Slackware) don't initialize /etc/mtab before checking non-root
5127 filesystems. (Slackware also doesn't check the root filesystem
5128 separately, and reboot if the root filesystem had changes applied to
5129 it, which is dangerous and broken, but there's nothing I can do about
5132 Make UUID library C++ friendly by adding appropriate extern "C"
5133 declarations and using const in the function declarations.
5135 Fix up the com_err texinfo file so that it can product a valid info
5136 file (previously, it could only be used to generate paper
5137 documentation using texinfo.tex).
5140 E2fsprogs 1.24a (September 2, 2001)
5141 ===================================
5143 Fix brown-paper bug in mke2fs which caused it to segfault when
5144 printing the version string.
5147 E2fsprogs 1.24 (August 30, 2001)
5148 ================================
5150 Revert the BLKGETSIZE64 support, since for some distributions, this
5151 ioctl has been used by an unofficial kernel patch to update the last
5152 sector on the disk, and this was causing disk corruption problems as a
5155 Mke2fs is now more careful about zapping swap space signatures and
5156 other filesystem/raid superblock magic values so that programs like
5157 mount who try to use hueristics to determine the filesystem type of a
5158 partition are less likely to be confused.
5160 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5161 regular file (since Andreas Dilger's on-line resizing tools will set
5164 Fixed some minor texinfo, man pages nits for spelling errors,
5165 texinfo warnings, etc. (Addresses Debian bug #110621.)
5167 E2fsprogs program no longer print the filesystem version number
5168 (i.e. 0.5b), since it only confuses people and doesn't serve any real
5171 E2fsck will once again compile under libc5, since it will supply its
5172 own version of strnlen if necesssary.
5174 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5175 when specifying the external journal device. tune2fs will also search
5176 devices looking for the externla journal debice when removing.
5178 E2fsprogs 1.23 (August 15, 2001)
5179 ================================
5181 Add initial support for extended attributes (EA); e2fsck will
5182 correctly handle a filesystem with EA's and check the EA blocks for
5185 E2fsck's symlink sanity checking has been cleaned up. It now checks
5186 the i_size value of fast symlinks, and checks for immutable flags
5187 being set of symlinks, etc.
5189 E2fsck now offers to clear inodes which are special files that have a
5190 non-zero i_blocks or i_size field. (The i_size field check was in the
5191 previous version of the code, but due to a bug it didn't offer to
5192 clear the inode unless i_size and i_size_high were both non-zero.)
5194 E2image can now create "raw" image files, which only contain the
5195 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5196 debugfs, etc., can be run directly on the raw image file.
5198 Add support for the 64-bit block device patches.
5200 Fixed bugs in creating external journals with a 1k blocksize.
5202 Add initial support for external journals (so long as the external
5203 journal only supports a single filesystem) in e2fsck.
5205 Remove requirement for needing to run fsck on a filesystem after
5206 removing a journal (either internal or external).
5208 The man pages now document how to create and manage external journals.
5210 Speed up the check of an ext3 filesystems by avoiding a needless flush
5211 of all of the superblock and block group descriptors.
5213 Speed up creating an internal journal using tune2fs in the case where
5214 the filesystem has a lot blocks already allocated.
5216 Tune2fs has been fixed to make sure that only error messages go to
5217 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5219 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5220 now not set the sparse_super feature. (Addresses Debian bug #108165)
5222 Add support in fsck for the filesystem type "auto".
5224 Fsck -A will not try to interpret device names for filesystems which
5225 have a pass number is 0. (Addresses Debian bug #106696).
5227 Fsck prints a warning message if now valid filesystems are passed to
5228 it. (Addresses Debian Bug #107458.)
5230 E2fsck now gives an explicit warning if there filesystem still has
5231 errors at the end of the run. (Addresses Debian bug #104502)
5233 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5234 reflects an error. E2fsck will also not run the orphan list if the
5235 filesystem contains errors, since the orphan list might be corrupted.
5237 E2fsck now prints the number of large files when given the -v option.
5239 Fixed minor memory leaks in e2fsck.
5241 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5244 E2fsprogs 1.22 (June 22, 2001)
5245 ==============================
5247 Fixed a bug in e2fsck's handling of orphan inodes which are special
5248 files (i.e., block/character device files, named FIFO's, etc.).
5250 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5251 tune2fs to fail at adding a journal to a mounted filesystem.
5253 Fixed a few big-endian bugs in e2fsprogs
5254 * The directory block functions were accidentally reporting
5255 some directories as corrupted when they weren't.
5256 * If e2fsprogs is compiled --disable-swapfs, the C language
5257 equivalents weren't being included for big-endian platforms.
5258 (Fixes Debian bug #101686).
5260 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
5265 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5266 ioctls, and allow them to be defined for non-i386 platforms.
5268 The uuid.h header file is now protected against multiple inclusions.
5270 E2fsprogs is now being developed using BitKeeper. Changed the test
5271 scripts to deal with BK's stripping CR characgters from text files,
5272 and changed the top-level Makefile.in to avoid including BitKeeper
5273 files when generating the source tarball.
5276 E2fsprogs 1.21 (June 15, 2001)
5277 ==============================
5279 Added new configure flags which allow a subset e2fsprogs to be built;
5280 this is most useful for boot floopies, since the resulting shared
5281 libraries and programs are slimmed down by removing features that
5282 aren't necessary for a boot floppy. The new flags that were added
5283 are: --disable-swapfs, which removes support for byte swapping old
5284 legacy PPC/68k filesystems, --disable-debugfs, which removes support
5285 for debugfs from the libext2fs library, --disable-imager, which
5286 removes support for the e2image program, and --disable-resizer, which
5287 removes support for resize2fs.
5289 E2fsck now prints the number of mounts or days elapsed since the last
5290 check when e2fsck is forced to check an otherwise clean filesystem.
5292 Tune2fs now prints an informative message about how often a filesystem
5293 will be checked when adding a journal to the filesystem, to remind the
5294 user that he/she may want to adjust those parameters using tune2fs
5297 Worked around hurd brain-damage which causes e2fsck to sometimes
5298 believe a filesystem is the root filesystem based on device numbers
5299 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5302 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5303 erroneous error with the -F option was specified.
5305 Fixed a ext3 recovery bug in the revoke handling; synchronized with
5308 Fixed two bugs in e2fsck's handling of dup block handling, dealing
5309 with relatively uncommon edge cases: a directory with an indirect
5310 block which is claimed by another file, and when the last inode in the
5311 filesystem has blocks claimed by another file.
5313 E2fsck now checks to see if the i_size field of a fast symlink is too
5314 big, and offers to clear the symlink if so.
5316 E2fsck now checks to see if i_size_high of special files is non-zero,
5317 and offers to clear i_size_high.
5319 Fix e2fsck's handling of incompatible journal flags so that the user
5320 has chance to abort, and then has the option to clear out the journal
5321 entirely. (Addresses Debian bug #98527.)
5323 Fixed a bug in fsck which could cause it to core dump if a mix of
5324 standard and non-standard device names are used in /etc/fstab.
5325 (Debian bug #100559)
5327 Fixed a bug in debugfs which caused read errors when copying a file to
5330 The debugfs set_super_value command can now modify the s_lastcheck field.
5332 Fixed a bug in lsattr and chattr which was accidentally introduced in
5333 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
5334 directories correctly because the change modified the layout of struct
5335 dirent to be incompatible with the libe2p shared library.
5337 Cleaned up the mke2fs manual page and included a discussion about why
5338 it's good to periodically check the filesystem even when journaling is
5344 Fix general gcc -Wall complaints.
5346 The types needed by the ext2 header files are now provided by
5347 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5349 Integers are now preferred to longs when trying to find a 32-bit type
5350 in ext2_types.h. Also, if linux/types.h has already been defined,
5351 don't try to redefine the types.
5353 Fixed make depend script so that it automatically corrects the
5354 pathname cleanups performed by make -M, so I don't have to fix them up
5357 Fixed the d_loaddump test case to be more robust, and not depend on
5360 Removed debugfs's dependence on pread(), which was accidentally
5361 intrudced in e2fsprogs 1.20
5363 Fixed a performance bug in the libext2fs's icount routine; the size
5364 estimate of the icount array was incorrectly being calculated.
5366 Removed use of the badblocks compatibility functions in the e2fsprogs
5369 Added paranoia code which protects against strange cases where /etc
5370 isn't on the root filesystem, or if /etc/mtab doesn't exist.
5372 The header file ext2_types.h is now installed.
5374 Autoconf is used to determine when we are on big-endian machines,
5375 instead of doing run-time tests, to save a few bytes of code.
5377 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5378 functions are no longer inline functions, which saves space and
5379 doesn't really cost any real performance.
5381 The ext2fs library no longer depends on the e2p library. (What need
5382 there was of it --- namely, fsetflags, was coded in-line).
5384 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5385 when the user is stupid and tries compiling the package using "make
5388 Miscellaneous code cleanups:
5389 * Added missing files from Makefile.in's SRCS file, so that
5390 their dependencies would be properly calculated.
5391 * Removed redundant code
5392 * Fixed comments in code
5393 * Removed no-longer unneeded argsused #pragma.
5396 E2fsprogs 1.20 (May 20, 2001)
5397 =============================
5399 Add support for replaying the ext3 journal purely in user mode,
5400 including handling the orphaned inode list. Used code contributed by
5401 Andreas Dilger, with bug fixes and the orphaned inode handling done
5404 The mke2fs and tune2fs programs can create or modify a filesystem to
5405 include an ext3 journal. Tune2fs also can be used to remove an ext3
5406 journal from a filesystem.
5408 E2fsck will now check for the existence of a linked list of orphan
5409 inodes in the superblock, and clear those inodes before starting the
5410 rest of the filesystem check (but after the journal playback).
5412 E2fsck now validates the file descriptor passed to the -C option,
5413 which saves against the completion bar getting written to an
5414 unexpected location, such as the disk being checked. (Debian
5415 bug/wishlist #55220)
5417 E2fsck will now bump the filesystem revision number from zero to one
5418 if any of the compatibility bits are set.
5420 Fixed a bug where a badly corrupted directory on a big endian system
5421 could cause e2fsck to die with a bus error. The
5422 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5423 the ext2 library now does alignment sanity checks on the rec_len field
5424 of the directory entry before using it.
5426 The ext2 library has been enhanced to make tune2fs safe to run on
5427 mounted filesystems. (Users could usually get away with using tune2fs
5428 on mounted filesystems before, but with the advent of ext3 and
5429 journaling, it became important to make tune2fs was *really* safe for
5430 use even when the filesystem being modified is mounted.) E2label is
5431 now implemented by tune2fs using an argv[0] dispatch, so that e2label
5432 is also now safe for use on mounted filesystems.
5434 Added a new program, e2image, which creates a backup of critical ext2
5435 filesystem data structures. The generated image file can be examined
5436 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
5437 the image file to help recover very badly damaged filesystems.
5439 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5440 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
5441 large file when deciding whether or not the filesystem has large files.
5443 Fixed lsattr and chattr so that they work correctly on large files.
5444 (Fixes Debian bug #72690.)
5446 Removed limitation in get_device_size() which imposed a one terrabyte
5447 filesystem limitation. (Most 2.2 kernels still have a signed int
5448 problem which cause 1 TB block device limitation. Fortunately, the
5449 kernel patches to fix this are much easier than fixing the 2TB
5450 limitation in the kernel. :-)
5452 A max_mount_count of zero is now treated as if no mount count were
5453 set. (Previously, no mount count was indicated by using -1, and a
5454 mount count of zero caused e2fsck to always be run.)
5456 Mke2fs supports two new filesystem types largefile and largefile4.
5458 Mke2fs now adds some randomness in s_max_mount_count so that multiple
5459 filesystems won't be all checked at the same time under normal
5462 Fixed bug in the progress bar printing code which could cause e2fsck
5463 to core dump on an illegal filesystem.
5465 Fixed bug in fsck which could allow more than one instance of e2fsck
5466 to be printing a progress bar. (Debian bug #65267)
5468 Fsck using a UUID or a LABEL specifier will work even if devfs is
5469 compiled into the kernel and not mounted. If the pathnames in
5470 /proc/partitions are incorrect, fsck will search /dev for the correct
5471 device (using the new ext2fs_find_block_device library function).
5472 Fsck now also checks the RAID devices first so that they are properly
5473 found when they are in use. Support has also been added to support
5474 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
5476 Fixed a bug in fsck which caused it not deal properly with 16
5477 byte long filesystem labels.
5479 Fsck's -t option has been made a lot more flexible. The semantics for
5480 what happens if a comma-separated list to fsck has been regularized,
5481 and it is now possible to filter what filesystems will get checked
5482 based what is in the filesystem's fstab entry's option field. (Debian
5485 The dumpe2fs program can now print out the group description
5486 information in hex, and also prints the location of the superblock and
5487 block group descriptor for those block groups that have them.
5489 Mke2fs now clears the ext2 superblock before it starts creating a
5490 filesystem, so that the superblock magic number is only written if the
5491 filesystem creation process successfully completes.
5493 The debugfs program's stat command now pretty-prints the blocks used
5494 by an inode so that it's more compact and informative.
5496 The debugfs stats command now uses the same libe2p code (which is used
5497 by dumpe2fs) to print the superblock header information. This is more
5498 complete, and it avoids a bit of code duplication.
5500 Added a new debugfs command, set_super_value (ssv) which allows the
5501 user to set arbitrary superblock fields.
5503 Debugfs was extended to support inode numbers in hex (by prefixing
5504 them with 0x), and so that modify_inode can set the inode generation
5505 number. Also, there is now a new function command called logdump
5506 which will dump an ext3 journal.
5508 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5511 Debugfs's dump command now stops immediately upon reporting a disk
5512 read error. (Fixed a bug in ext2fs_file_read library routine which
5513 caused debugfs not to stop.) (Debian bug #79163)
5515 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5516 checked before /etc/mtab is used, since /proc/mounts is more likely to
5519 Added portability fixes for Solaris and Linux/ia64.
5521 Various manual pages were clarified and cleaned up. (Fixed debian
5522 bugs #63442, #67446, and #87216)
5528 The e2fsck message printer now supports %Iu and %Ig, which will print
5529 out the inode's user and group owners, respectively.
5531 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5532 that no longer dependent on the system having the correct version of
5533 the kernel header files.
5535 Added a new function to libext2, ext2fs_find_block_device(), which
5536 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5537 device given its device number.
5539 Added a new function to libext2, ext2fs_sync_device, which centralizes
5540 all of the places which might try to use the BLKFLSBUF or FDFLUSH
5541 ioctls (and usually failing to define them since the system header
5542 files don't usually do this for us, and we're trying to avoid usage of
5543 kernel include files now).
5545 Added new utility programs in tests/progs: random_exercise and
5546 hold_inode. They aren't built by default; they're useful for
5547 exercising ext3 filesystem code.
5549 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5550 the filesystem close functions to only update the superblock, and to
5551 not touch the block group descriptors. Needed by tune2fs when
5552 modifying a mounted filesystem.
5554 Got rid of struct ext2fs_sb and replaced it with the standard struct
5555 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
5556 source (but not binary) compatibility of some users of the ext2
5557 library. Those applications should just simply do a global search and
5558 replace of struct ext2fs_sb with struct ext2_super_block, and include
5559 the new header file <ext2fs/ext2_fs.h> which defines it.
5561 The ino_t type has been renamed ext2_ino_t to protect applications
5562 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5563 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
5564 unexpected ABI change.
5566 The Makefiles have been reworked so that "make check" can be run from
5567 the top-level Makefile.
5569 Fix general gcc -Wall complaints and removed dead code.
5571 Remove use of NOARGS, because we assume everyone does ANSI C these
5574 Added build-rpm script from sct.
5576 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
5579 New function ext2fs_flush_icache which must be called if the
5580 application program modifies the inode table blocks without going
5581 through ext2fs_write_inode() interface.
5583 New ext2fs_check_mount_point() function, which will return the mount
5584 point of a device if mounted.
5586 The io_channel abstraction now has an optional interface,
5587 io_channel_write_range, which allows specific byte ranges to be
5590 The unix_io IO channel now supports write-through caching, so that
5591 journal creation is more efficient.
5593 Added x86 assembly language routines to support byte swapping, to
5594 reduce executable size.
5596 Fixed bug in the utility program subst so that it's possible to
5597 replace a substitution variable with a zero-length string.
5599 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5600 slipped into some of the problem number.
5602 E2fsprogs 1.19 (July 13, 2000)
5603 ==============================
5605 Release the resize2fs program since the timeout before it could
5606 be released under the GPL has finally expired.
5608 Add experimental support needed for the ext2 compression patches.
5609 This requires compiling e2fsprogs with the --enable-compression flag
5610 to the configure script.
5612 Added ext3 journalling support. E2fsck will run the journal (if
5613 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
5614 installed as a symlink to e2fsck. Fsck has been taught about ext3,
5615 and treats it the same as ext2 in terms of the progress bar logic.
5616 Dumpe2fs will display the superblock journaling information if the
5617 filesystem has a journal. The ext2 library will now permit opening an
5618 ext3 filesystem with the recovery flag set. This is necessary for
5619 on-line dump's to work correctly, but there may be issues with this
5620 working well since ext3 is much less agressive about syncing blocks to
5621 the filesystem, since they're safe on the journal.
5623 Tune2fs and e2fsck have been changed to allow the mount_count check to
5624 be disabled by setting max_mount_count to -1. (This was already
5625 supported by the kernel.)
5627 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5628 are used for ext3 as well.
5630 Added internationalization support for e2fsprogs; must be enabled
5631 by passing --enable-nls to configure.
5633 Always use the provided ext2fs header files to insulate ourselves from
5634 kernel version changes. Which include files are used by e2fsprogs
5635 have also been cleaned up to improve portability.
5637 Limit the number of times that e2fsck updates the progress bar so that
5638 people who are booting using a 9600 baud console don't get swampped by
5641 Improved the loop detection algorithm in e2sck's pass #3 so that it is
5642 much, much faster for large filesystems with a large number of
5645 The memory footprint for e2fsck is now slightly smaller than before.
5647 E2fsck now checks if special devices have a non-zero size, and offers
5648 to clear the size field if it finds such an inode.
5650 E2fsck now checks if special devices have the append-only flag set,
5651 and offers to clear the inode.
5653 E2fsck now properly handles some "should never fail" cases during a
5654 bitmap copy in pass5.
5656 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5658 E2fsck now calculates the correct location of the backup superblock in
5659 the case of filesystem blocksizes > 1k.
5661 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5662 which normally didn't cause problems under most filesystem parameters,
5663 but could cause a valid superblock to be rejected in extreme cases.
5664 Other checks for validating superblock values were made more
5667 Added non-destructive write testing to the badblocks program, courtesy
5668 of David Beattie. The badblocks also now has an option to input the
5669 current set of bad blocks, so that known bad blocks are skipped to
5670 speed up the badblocks test. There is also a persistent rescan
5671 feature which causes badblocks to run until it has completed some
5672 number of passes without discovering any new bad blocks.
5674 Badblocks now checks to see if the device is mounted and refuses to do
5675 the tests involving writing to the device if it is mounted. Also,
5676 badblocks now allows the number of blocks to be checked to be
5677 defaulted to the size of the partition.
5679 Fixed a bug in fsck which didn't allow non-root users to be able to
5680 check filesystems if there were any LABEL= or UUID= entries in
5683 The Hurd doesn't support the filetype filesystem feature. The mke2fs
5684 program now makes sure that for the Hurd, the filestype feature is
5685 turned off. E2fsck will check to see if the filetype feature is
5686 turned on for Hurd filesystems, and offer to turn off the feature.
5688 Mke2fs now has a safety check to make sure the number of blocks do not
5689 exceed 32 bits even on a 64 bit platform.
5691 Really fixed a bug in fsck to allow "fsck -As" to run interactive
5692 fsck's. (For those people who like to do interactive fsck's in the
5695 Debugfs has a few new features: the rdump command, which will do a
5696 recursive dump of a directory and all of its contents, and the lcd
5697 command which does a local chdir (much like the ftp command of the
5698 same name). In addition, the debugfs program and the open_filesystem
5699 command now takes three new options: -b and -s, which allows the
5700 blocksize and superblock location to be specified, and the -c option
5701 which is used in catastrophic situations where the block group
5702 descriptors are corrupt. If the -c option is specified, debugfs will
5703 skip trying to read in the block and inode bitmaps.
5705 Debufs's lsdel command was fixed to handle bad blocks in the inode
5708 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
5711 General improvements in error messages
5713 - Mke2fs prints a sane error message if the partition size is zero
5714 (usually because the partition table wasn't reread by the
5715 kernel due to the partition being busy), instead of "invalid
5716 argument passed to ext2 library while initializing superblock".
5718 - Fsck now prints more self-explanatory message if an invalid UUID=
5719 or LABEL= specification is passed to it.
5721 UUID library changed to use the LGPL.
5723 Fixed a bug in the UUID library where very rapid calls to the
5724 time-based UUID generator could cause duplicate UUID's to be returned.
5725 This was not a problem for e2fsprogs, but it could be a problem for
5726 other users of the library.
5728 Make the UUID library more robust in the face of missing or an
5729 improper /dev/urandom or /dev/random files.
5731 Added some random portability fixes for Solaris.
5733 Some minor man page updates.
5735 Fixed a memory leak in the ss library.
5741 We now try to use lseek64 and open64 from the LFS if possible.
5743 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5746 The mark and unmark bitmap functions now return the previous state of
5747 the bit that was being changed, which is useful for some speed
5750 The following functions have been added to enhance the badblocks list
5751 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5752 ext2fs_badblocks_equal.
5754 The ext2 header files now have the latest journalling fields to the
5757 The ext2fs_mkdir function in libext2fs now properly backs out of error
5758 conditions robustly.
5760 Cleaned up makefiles:
5761 - to cleanly compile with the -j flag.
5762 - so distclean removes all generated files.
5763 - so in case of an error while installing header files, the make aborts.
5765 Fix test_script so that it works correctly when compiling in the
5768 The random UUID generation routine has been made slightly better in
5769 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5770 is still not recommended if /dev/random doesn't exist, however; it's
5771 better to use the time/ethernet MAC address UUID in this case.)
5773 Clean up the build process so it's more friendly in case of missing
5776 The ext2fs header file can now be #include'd into C++ programs.
5778 The e2p.h header file is now installed.
5780 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5784 E2fsprogs 1.18 (November 10, 1999)
5785 ==================================
5787 Fix a core dumping bug in e2fsck if an imagic inode is present or
5788 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5789 has to restart pass 1 processing. E2fsck now closes the filesystem
5790 before freeing a large number of its data structures, so in the case
5791 of future memory faults, at least the fixed filesystem will be fully
5794 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5795 imagic inode, it will offer to clear the imagic flag.
5797 E2fsck will now offer to clear the immutable flag on special files
5798 (device/socket/fifos) when running it in non-preen mode.
5800 E2fsck will now set the filetype when creating /lost+found, and when
5801 connected orphaned inodes to /lost+found.
5803 Debugfs's ncheck and icheck commands now handles the case where there
5804 are bad blocks in the inode table without bombing out.
5806 The badblocks list processing code has been made more efficiently for
5807 appending a large number of (ordered) badblocks to the badblocks list.
5809 Some minor man page updates.
5811 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5812 mode, but some people like to do this in boot scripts for silly reasons).
5817 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5818 with the problem code convention.
5820 The badblocks list regression test program has been updated to work
5821 with previously made API name changes.
5823 The ext2fs_free() command now uses the new badblocks API to avoid
5824 using the compatibility layer.
5826 Added new regression test cases; the run_e2fsck test script now
5827 supports the ability for a test case to run a prepratory command
5828 before running e2fsck.
5830 E2fsprogs 1.17 (October 26, 1999)
5831 =================================
5833 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5836 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5837 thus potentially causing problems if a binary UUID contained a NULL
5840 E2fsck now uses stricter checks for directory entries in pass 2:
5841 zero-length filenames are not allowed; neither are 8 byte long
5844 The debugfs "dirty" command now clears the filesystem valid bit.
5845 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5846 bit in the in-core superblock image. The new functionality is more
5847 what the user expects, and is more useful.)
5849 Added a debugging hook to test parallel fsck; if the environment
5850 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5851 will be checked in parallel when they normally would not be.
5856 Fixed some #ifdef's for compilation under the Hurd OS.
5858 Fixed minor W2K compatibility problems.
5860 Fixed some miscellaneous GCC warnings.
5863 E2fsprogs 1.16 (October 22, 1999)
5864 =================================
5866 Fixed a race condition bug in fsck; when printing a progress bar, if
5867 checking multiple filesystems in parallel, it was possible for fsck to
5868 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5869 handler, which would cause it to terminate with a signal 10.
5871 E2fsck now properly handles filesystems that have the
5872 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5873 filesystem into using or not using FILETYPE feature.
5875 E2fsck now properly handles filesystems that have the IMAGIC feature
5876 turned on (this is used on Linux AFS servers).
5878 The mke2fs program now creates filesystems that have the filetype and
5879 sparse_superblock features enabled by default, unless it is run on a
5880 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5881 so there is now a new flag -O which allows the user to specify with
5882 which features she would like to create the filesystem; "mke2fs -O
5883 none" will create a filesystsem compatible with 2.0 kernels.
5885 The tune2fs program now has a -O option which allows the user to set
5886 and reset "safe" filesystem features. Currently, the only ones which
5887 allows to be modified are the filetype and sparse_superblock features.
5888 Note setting or clearing either feature will require running e2fsck on
5889 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5890 requires that there is enough free space on the filesystem for the
5891 extra superblocks which will be created by e2fsck.)
5893 Debugfs can now set and print filesystem features in the superblock
5894 using the "features" command. Dumpe2fs will print out the complete
5895 set of features when listing the superblock.
5897 Dumpe2fs has new options -f (force) and -h (header-only).
5899 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5900 message to come up. This could happen when decrementing or
5901 incrementing a link count could result in an overflow.
5903 Fixed a bug in e2fsck where the block count on the lost+found
5904 directory would not be properly incremented when the directory was
5905 expanded to the point where an indirect block needed to be allocated.
5907 E2fsck now makes some additional sanity checks on the superblock to
5908 avoid crashing or giving a memory allocation error if some of the
5909 values in the superblock are unresonable (but the superblock otherwise
5912 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5913 require two passes to completely fix the filesystem. This happened if
5914 an inode claimed blocks that was part of the filesystem metadata
5915 (typically, when garbage was written into an inode table or indirect
5916 block, since this kind of filesystem corruption normally doesn't
5919 On the Alpha, glibc declares st_flags although it isn't actually used;
5920 the configure script was improved to detect this case so that
5921 e2fsprogs can avoid using the non-functional stat field.
5923 The manual pages were updated to use a more consistent formatting
5924 style consistent with standard Unix man pages. Mke2fs's man page
5925 added documentation for a few previously undocumented options.
5927 Fixed minor display bugs in tune2fs and mke2fs.
5932 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5934 Added features to parse and print feature strings into the e2p library.
5935 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5937 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5938 whose directory entries contain proper filetype information if the
5939 filesystem supports it.
5941 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5942 the directory entry filetype information. This is used to set the
5943 directory entry filetype information if the filesystem supports it.
5945 Fixed a bug in ext2fs_expand_dir() where the block count in a
5946 directory's inode would not be properly incremented when the directory
5947 was expanded to the point where an indirect block needed to be
5951 E2fsprogs 1.15 (July 18, 1999)
5952 ==============================
5954 Add configuration checks so that e2fsprogs will compile cleanly on
5955 Linux 2.3 kernels that have renamed i_version to i_generation.
5957 E2fsck now prints a progress/completion bar (and not just a simple
5958 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5959 signal. Fsck will automatically manage the (potentially muliple)
5960 e2fsck processes to print completion bars if it is given a -C option,
5961 with the right thing happening if multiple filesystems are being
5962 checked in parallel.
5964 Mke2fs now has better automatic hueristics to determine the filesystem
5965 parameters to be used for a particular filesystem. Added a new option
5966 -T which allows the user to specify how the filesystem is to be used,
5967 which helps mke2fs do a better job selecting the filesystem parameters.
5969 Mke2fs now creates revision 1 filesystems by default, and with the
5970 sparse superblock feature enabled. The sparse superblock feature is
5971 not understood by Linux 2.0 kernels, so they will only allow read-only
5972 mounts of filesystems with this sparse superblocks.
5974 Fix bug where if /dev/null couldn't be opened (should never happen),
5975 e2fsck would hang in a tight loop.
5977 Make e2fsck handle the case where /lost+found isn't a directory.
5979 E2fsck now uses mallinfo if it exists to get accurate statistics about
5982 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5983 inode had any problems before connecting it to /lost+found.
5985 Add check to e2fsck so it makes sure that total number of inodes in
5986 the filesystem is a sane number.
5988 Fix fencepost error when clearing an the end of the block bitmap which
5989 caused the last block in the bitmap not to get cleared.
5991 Cleaned up a number of messages in e2fsck:
5992 * The message "Group's #'s copy of the group descriptor..."
5993 was fixed so that the correct number would be displayed.
5994 * Added missing space in the "disk write-protected" error messsage
5995 * Cleaned up the error message printed when a non-interactive
5996 e2fsck needs to abort a check because the filesystem
5997 appears to be mounted.
5999 Added a new command-line utility, uuidgen, which will create and print
6002 Make debugfs's icheck command more robust by checking to make sure an
6003 inode has valid blocks before interarting over the inode's blocks.
6005 UUID generation now uses a random-based scheme whenever possible to
6006 prevent potential privacy problems.
6008 Man pages for all of the UUID functions in the lirbary were added.
6010 Fixed bug in fsck so it won't coredump if a filesystem not in
6011 /etc/fstab is given to it.
6013 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6014 that most of the other mount utilities understands.
6016 Mke2fs will make a filesystem even if it appears mounted if the force
6019 Dumpe2fs has new command-line options which allow a filesystem expert
6020 to specify the superblock and blocksize when opening a filesystem.
6021 This is mainly useful when examining the remains of a toasted
6024 The badblocks program has been updated to display correctly on disks
6025 with large block numbers.
6027 The badblocks program no longer gives spurious errors when errors
6028 occur on non-block boundaries, which is common if the blocksize is
6031 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6032 MKE2FS_SYNC environment variable is set. This is to work around a VM
6033 bug in the 2.0 kernel. I've heard a report that a RAID user was able
6034 to trigger it even using a 2.2 kernel, but hopefully it will not be
6035 needed for most Linux 2.2 users.
6037 Fixed miscellaneous documentation and man pages.
6042 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6043 in e2fsck's pass1.c really should have been static.
6045 The return value of the uuid_compare() function was changed to make it
6046 match with the convetions used by strcmp, memcmp, and Paul Leach's
6047 UUID sample document.
6049 The "make depend" process has now been made more automated; it now
6050 automatically word-wraps the dependencies, and only replaces source
6051 Makefile.in if there has been a change in the dependencies. Also, a
6052 top-level "make depend" now recurses through all the subdirectories
6055 The Makefile in .../util has been changed so that subst is built using
6056 the native C compiler during a cross-compilation, since the subst
6057 program is only used during the build process. Also add an explicit
6058 rule to build util/subst by cd'ing to the correct directory and
6061 The man directories are defined in terms mandir, so that the configure
6062 script can override the location of the manual pages.
6064 The config files have been updated to recognize new machine types for
6065 both the i386 and alpha families.
6067 Fsck has been modified so that it will accurately create an
6068 fsck_instance even when the noexecute flag is set. This allows for
6069 accurate debugging of the fsck pass structure. Also, when the verbose
6070 flag is given twice, fsck will print debugging information about when
6071 fsck is waiting for jobs to finish.
6074 E2fsprogs 1.14 (January 9, 1999)
6075 ================================
6077 Fix the fstab parsing code so that it can handle blank lines and
6078 comment characters. Also, missing pass numbers need to be treated as
6081 Fixed a bug in e2fsck where under some circumstances (when e2fsck
6082 needs to restart processing after fixing an egregious inconsistency)
6083 it would try to access already freed memory.
6085 E2fsck now prints non-printable characters in directory entries and
6086 pathnames using '^' and 'M-' notation.
6088 Fixed chattr so that it will ignore symbolic links when doing
6089 recursive descent traversals. For both chattr and lsattr, no longer
6090 print the version string unless the -V option is given.
6092 Allow the system administrator to directly specify the number of
6093 inodes desired in the filesystem, for some special cases where this is
6096 Fix portability problems so that e2fsprogs can be compiled under Linux
6097 1.2 systems and Solaris systems.
6099 Update the config.guess file with a more recent version that will
6100 identify newer Linux platforms.
6105 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6106 an inode number of zero is passed to them.
6108 E2fsprogs 1.13 (December 15, 1998)
6109 ==================================
6111 Fixed a bug in debugfs where an error messages weren't getting printed
6112 when the ext2 library routines to read inodes returned errors in the
6113 stat, cmri and rm commands.
6115 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6116 provided, it won't create an inode table smaller than the minimum
6117 number of inodes required for a proper ext2 filesystem.
6119 Fsck now parses the /etc/fstab file directly (instead of using
6120 getmntent()), so that it can distinguish between a missing pass number
6121 field and pass number field of zero. This caused problems for
6122 diskless workstations where all of the filesystems in /etc/fstab have
6123 an explicit pass number of zero, and fsck could not distinguish this
6124 from a /etc/fstab file with missing pass numbers.
6126 E2fsck will create a /lost+found directory if there isn't one in the
6127 filesystem, since it's safer to create the lost+found directory before
6130 Fixed e2fsck so that it would detect bogus immutable inodes which
6131 happen to be sockets and FIFO files, and offer to clear them.
6133 If a filesystem has multiple reasons why it needs to be checked, and
6134 one of the reasons is that it is uncleanly mounted, e2fsck will print
6135 that as the reason why the filesystem is being checked.
6137 Cleaned up the output routines of mke2fs so that it doesn't overflow
6138 an 80 column display when formating really big filesystems.
6140 Added a sanity check to e2fsck to make sure that file descriptors 0,
6141 1, 2 are open before opening the hard disk. This avoids a problem
6142 where a broken program might exec e2fsck with those file descriptors
6143 closed, which would cause disastrous results if the kernel returns a
6144 file descriptor for the block device which is also used by FILE *
6147 Fixed up the e2fsck progress reporting functions so that the values
6148 reliably reach 100% at the completion of all of the e2fsck passes.
6150 Fixed minor documentation bugs in man pages and usage messages.
6155 Fixed a number of lint warnings in the ext2fs library and potential
6156 portability problems from other OS's header files that might define
6157 CPP macros for names like "max" and "min".
6159 ext2fs_badblocks_list_add() has been made more efficient when it needs
6160 to grow the bad blocks list.
6162 Fixed a bug in e2fsck which caused it to dereference a freed pointer
6163 just before exiting.
6165 Fixed the substition process for generating the mk_cmds and compile_et
6166 scripts so that they will work outside of the build tree.
6168 Add sanity check to e2fsck so that if an internal routine
6169 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6170 and causing a core dump. This should never happen, but...
6172 E2fsprogs 1.12 (July 9, 1998)
6173 ==================================
6175 E2fsprogs now works with glibc (at least with the version shipped wtih
6176 RedHat 5.0). The ext2fs_llseek() function should now work even with
6177 i386 ELF shared libraries and if llseek() is not present. We also
6178 explicitly do a configure test to see if (a) llseek is in libc, and
6179 (b) if llseek is declared in the system header files. (See standard
6180 complaints about libc developers don't understand the concept of
6181 compatibility with previous versions of libc.)
6183 The ext2fs library now writes out the block group number in each of
6184 the superblock copies. This makes it easier to automatically
6185 determine the starting block group of the filesystem when the block
6186 group information is trashed.
6188 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6189 which means that e2fsprogs will ignore the high 8 bits of the
6190 directory entry's name_len field, so that it can be used for other
6193 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6194 E2fsprogs will now support filesystems with 64-bit sized files.
6196 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6198 Added new program "e2label", contributed by Andries Brouwer. E2label
6199 provides an easy-to-use interface to modify the filesystem label.
6201 Fixed bug so that lsattr -v works instead of producing a core dump.
6203 Fixed a minor bug in mke2fs so that all groups with bad superblock
6204 backup blocks are printed (not just the first one).
6206 Mke2fs will check the size of the device, and if the user specifies a
6207 filesystem size larger than the apparent size of the device it will
6208 print a warning message and ask if the user wants to proceed.
6210 E2fsck has a new option -C, which sends completion information to the
6211 specified file descriptor. For the most part, this is intended for
6212 programs to use, although -C 0 will print a spinning character to the
6213 stdout device, which may be useful for users who want to see something
6214 happening while e2fsck goes about its business.
6216 Fixed a bug in e2fsck which could cause a core dump when it needs to
6217 expand the /lost+found directory, and sometimes the bitmaps haven't
6218 been merged in. Also fixed a related bug where ext2fs_write_dir_block
6219 was used to write out a non-directory block. (Which would be bad on a
6220 non-Intel platform with byte swapping going on.)
6222 Fixed bug in e2fsck where it would print a "programming error" message
6223 instead of correctly identifying where a bad block was in used when
6224 the bad block was in a non-primary superblock or block group
6225 descriptor. Also fixed a related bug when sparse superblocks are in
6226 use and there is a bad block where a superblock or block group
6227 descriptor would have been in a group that doesn't include a
6230 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6231 the block group descriptor table is corrupt, it was possible to try to
6232 allocate a huge array, fail, and then abort e2fsck.
6233 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6234 and subsitutes reasonable values if the descriptors are obviously bogus.
6236 If e2fsck finds a device file which has the immutable flag set and the
6237 i_blocks beyond the normal device number are non-zero, e2fsck will
6238 offer to remove it, since it's probably caused by garbage in the inode
6241 When opening a filesystem, e2fsck specially checks for the EROFS error
6242 code, and prints a specific error message to the user which is more
6245 If the filesystem revision is too high, change the e2fsck to print
6246 that this is either because e2fsck is out of date, or because the
6247 superblock is corrupt.
6249 E2fsck now checks for directories that have duplicate '.' and '..'
6250 entries, and fixes this corruption.
6252 E2fsck no longer forces a sync of the filesystem (with attendant sleep
6253 calls) at all times. The ext2fs_flush() function now performs a sync
6254 only if it needed to write data blocks to disk.
6256 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6257 certain errors would not be properly reported.
6259 Updated and expanded a few points in the man pages which users
6260 complained wheren't explicit enough.
6262 Added special case byte-swapping code if compiling on the PowerPC, to
6263 accomodate the strange big-endian variant of the ext2 filesystem that
6264 was previously used on the PowerPC port.
6270 Removed C++ keywords from the ext2fs libraries so that it could be
6273 E2fsck's internal organization has now been massively reorganized so
6274 that pass*.c don't have any printf statements. Instead, all problems
6275 are reported through the fix_problem() abstraction interface. E2fsck
6276 has also been revamped so that it can be called as a library from a
6279 Added new fileio primitives in libext2fs for reading and writing
6280 files on an unmounted ext2 filesystem. This interface is now used by
6283 Added a new libext2fs function for mapping logical block numbers of
6284 a file to a physical block number.
6286 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6287 a block, zeros it, and updates the filesystem accounting records
6290 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6291 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
6293 The libext2fs functions now use a set of memory allocation wrapper
6294 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6295 instead of malloc, free, and resize. This makes it easier for us to
6296 be ported to strange environments where malloc, et. al. aren't
6297 necessarily available.
6299 Change the libext2fs fucntion to return ext2-specific error codes
6300 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6301 and depending on the existence of system error codes (such as EEXIST
6304 Renamed io.h to ext2_io.h to avoid collision with other OS's header
6307 Add protection against ext2_io.h and ext2fs.h being included multiple
6310 The types used for memory lengths, etc. have been made more portable.
6311 In generla, the code has been made 16-bit safe. Added Mark
6312 Habersack's contributed DOS disk i/o routines.
6314 Miscellaneous portability fixes, including not depending on char's
6317 The io_channel structure has a new element, app_data, which is
6318 initialized by the ext2fs routines to contain a copy of the filesystem
6321 ext2fs_check_directory()'s callback function may now return the error
6322 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6323 really do the checking, despite the presence of the callback function.
6326 E2fsprosg 1.11 (June 17, 1997)
6327 ==============================
6329 Fixed e2fsck to detect (previously ignored) conflicts between the
6330 superblock or block group descriptors and block bitmaps, inode
6331 bitmaps, and inode tables.
6333 Fixed bug in e2fsck so that when the message printed out when a block
6334 or inode bitmap conflicts with other data, it has the correct group
6337 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6338 to badblocks. This meant that not all of the filesystem was being
6339 tested for bad blocks!
6341 Fixed an array boundary overrun case which cropped up in
6342 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
6345 Adjusted the number of columns printed by mke2fs when displaying the
6346 superblock backups to avoid running over 80 columns when making a
6347 really big filesystem.
6349 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6350 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6351 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6356 Fixed install rule in lib/ss so that ss_err.h is actually getting
6359 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6360 bassed back to the caller.
6362 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6363 setting the current inode number (which meant this function wasn't
6366 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6367 blocks in the bitmap when increasing the size of the bitmap.
6369 Changed the initial number of blocks allocated by ext2fs_init_dblist()
6370 to be more realistic.
6372 Added a new function ext2fs_allocate_group_table, which sets up the
6373 group descriptor information (and allocates inode and block bitmaps,
6374 and inode tables for a particular group). The function was created by
6375 factoring out code form ext2fs_allocate_tables().
6377 Added a new function ext2fs_move_blocks which takes a bitmap of the
6378 blocks to be moved, and moves them to another location on the
6381 Make the unix_io channel's io_channel_flush implementation calls sync()
6382 to to flush the kernel buffers to disk.
6384 Added a new function ext2fs_dblist_count returns the number of
6385 directory blocks in dblist.
6388 E2fsprogs 1.10 (April 24, 1997)
6389 ===============================
6391 Mke2fs once again defaults to creating revision #0 filesystems, since
6392 people were complaining about breaking compatibility with 1.2 kernels.
6393 Warning messages were added to the mke2fs and tune2fs man pages that
6394 the sparse superblock option isn't supported by most kernels yet (1.2
6395 and 2.0 both don't support parse superblocks.)
6397 Added new flag to mke2fs, -R <raid options>, which allows the user to
6398 tell mke2fs about the RAID configuration of the filesystem. Currently
6399 the only supported raid option is "stride" which specifies the width
6402 Fixed bug in e2fsck where pass1b would bomb out if there were any
6403 blocks marked bad in the inode table.
6405 Fixed rare bug in mke2fs where if the user had a very unlucky number
6406 of blocks in a filesystem (probability less than .002) the resulting
6407 filesystem would be corrupt in the last block group.
6409 Fixed bug where if e2fsck tried to allocate a block to fix a
6410 filesystem corruption problem and the filesystem had no free blocks,
6411 ext2fs_new_block() would loop forever.
6413 The configure script now checks explicitly to see if "-static" works,
6414 since that can't be assumed to be true --- RedHat doesn't install
6415 libc-static by default.
6417 Fixed bug in libext2's block iterator functions where under some
6418 cirmcustances, file with holes would cause the bcount parameter to the
6419 callback function to be incorrect. This bug didn't affect any of
6420 e2fsprogs programs, but it was discovered by Paul Mackerras, the
6421 author of the PPC boot loader.
6423 Removed use of static variables to store the inode cache in libext2fs.
6424 This caused problems if more than one filesystem was accessed via
6425 libext2fs (static variables in libraries are generally a bad idea).
6426 Again, this didn't affect e2fsprogs programs, but it was discovered by
6429 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6430 will compile cleanly with 1.2.13 kernels (even with a.out shared
6436 Added new functions to duplicate an ext2 filesystem handle, and its
6437 associated substructure. New functions: ext2fs_dup_handle(),
6438 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6439 Other structures, such as the io_channel and the inode_cache, now have
6440 a ref count so that they only get freed when they are no longer used
6441 by any filesystem handle. (These functions were added as part of the
6442 development effort for an ext2 resizer).
6444 E2fsprogs 1.09 (April 14, 1997)
6445 ===============================
6447 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6448 accidentally introduced in the 1.08 release. The overhead calculation
6449 was accidentally removed, which caused ext2fs_initialize() to not
6450 notice when the filesystem size needed to be adjusted down because
6451 there wasn't enough space in the last block group.
6453 Fixed bug in version parsing library routine; it was always parsing
6454 the library version string, instead of using the passed-in string.
6456 Clarified chattr man page.
6458 E2fsprogs 1.08 (April 10, 1997)
6459 ===============================
6461 E2fsck 1.07 was very slow when checking very large filesystems with a
6462 lot of files that had hard links (i.e., news spools). This was fixed
6463 by seriously revamping the icount abstraction. Added a formal test
6464 suite for the icount abstraction.
6466 Debugfs now has a "-l" option to the "ls" command, which lists the
6467 inode number, permissions, owner, group, size, and name of the files
6470 Fix a bug in e2fsck where when a directory had its blocks moved to
6471 another location during the pass 1b processing, the directory block
6472 list wasn't updated, so pass 2 wouldn't check (and correct) the
6473 correct directory block.
6475 E2fsck will now treat inodes which contain blocks which are claimed by
6476 the filesystem metadata by treating them as multiply claimed blocks.
6477 This way, the data in those blocks can be copied to a new block during
6478 the pass 1b--1d processing.
6480 E2fsck will attempt to determine the correct superblock number and
6481 display it in the diagnostic and warning messages if possible.
6483 Add support for a new (incompatible) feature, "sparse_super". This
6484 feature reduces the number of blocks which contain copies of backup
6485 superblocks and block group descriptors. (It is only an incompatible
6486 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
6487 support a new -s option; e2fsck will recognize filesystems built with
6488 this feature turned on.
6490 E2fsck now checks the library to make sure is the correct version,
6491 using new library functions. (This helps to diagnose incorrectly
6492 installed e2fsprogs distributions.)
6494 Dumpe2fs now prints more information; its now prints the the
6495 filesystem revision number, the filesystem sparse_super feature (if
6496 present), the block ranges for each block group, and the offset from
6497 the beginning of the block group.
6499 Mke2fs now distributes the inode and block bitmap blok so that the
6500 won't be concentrated in one or two disks in RAID/striping setups.
6501 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6502 choose the largest blocks per group that be chosen. (For 2k blocks,
6503 you can have up to 16384 blocks/group; for 4k blocks, you can have up
6504 to 32768 blocks/group.) Previously mke2fs would not allow
6505 specification of more than 8192 blocks per group, even if you were
6506 using a 2k or 4k block group.
6511 Added a new function ext2fs_create_icount2() which takes a "hint"
6512 argument. This hint argument presets the icount array with the list
6513 of inodes which actually need to be in the icount array. This really
6514 helps to speed up e2fsck.
6516 Added a new function ext2fs_icount_validate() which checks the rep
6517 invariant for the icount structure. This is used mostly for testing.
6519 The error mesasage given when a bad inode number is passed to
6520 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6521 EXT2FS_UNMARK_ERROR).
6523 Added a new function ext2fs_set_dir_block which sets the block of a
6524 dblist entry, given the directory inode and blockcnt.
6526 Added a new function ext2fs_get_library_version() which returns the
6527 current library version, and ext2fs_parse_version_string() which
6528 returns a version number based on a e2fsprogs version string.
6530 The icount functions will return EINVAL if the passed in inode number
6533 E2fsprogs 1.07 (March 9, 1997)
6534 ==============================
6536 E2fsck is now uses much less memory when checking really large
6537 filesystems (or rather, filesystems with a large number of inodes).
6538 Previously a filesystem with 1 million inodes required 4 megabytes of
6539 memory to store inode count statistics; that storage requirement has
6540 now been reduced to roughly half a megabyte.
6542 E2fsck can now properly deal with bad blocks appearing inside the
6543 inode table. Instead of trying to relocate the inode table (which
6544 often failed because there wasn't enough space), the inodes in the bad
6545 block are marked as in use.
6547 E2fsck will automatically try to use the backup superblocks if the
6548 primary superblocks have a bad magic number or have missing meta-data
6549 blocks (or meta-data blocks which are out of range).
6551 E2fsck's pass 3 has been made more efficient; most noticeable on
6552 filesystems with a very large number of directories.
6554 Completely revamped e2fsck's system of printing problem reports. It
6555 is now table driven, to make them more easily customizeable and
6556 extendable. Error messages which can be printed out during preen mode
6557 are now one line long.
6559 Fixed e2fsck's filesystem swapping code so that it won't try to swap
6560 fast symbolic links or deleted files.
6562 Fixed e2fsck core dumping when fixing a filesystem which has no
6563 directories (not even a root directory).
6565 Added a check to e2fsck to make sure that the length of every
6566 directory entry is a multiple of 4 (since the kernel complains if it
6569 Added a check to e2fsck to make sure that a directory entry isn't a
6570 link to the root directory, since that isn't allowed.
6572 Added a check to e2fsk to now make sure the '.' and '..' directory
6573 entries are null terminated, since the 2.0 kernel requires it.
6575 Added check to write_bitmaps() to make sure the superblock doesn't get
6576 trashed if the inode or block bitmap is marked as being block zero.
6578 Added checking of the new feature set fields in the superblock, to
6579 avoid dealing with new filesystem features that this package wasn't
6582 Fixed a fencepost error in ext2fs_new_block() which would occasionally
6583 try to allocate a block beyond the end of a filesystem.
6585 When the UUID library picks a random IEEE 802 address (because it
6586 can't find one from a network card), it sets the multicast bit, to
6587 avoid conflicting with a legitimate IEEE 802 address.
6589 Mke2fs now sets the root directory's owner to be the real uid of the
6590 user running mke2fs. If the real uid is non-zero, it also sets
6591 the group ownership of the root directory to be the real group-id of
6592 the user running mke2fs.
6594 Mke2fs now has more intelligent error checking when it is given a
6595 non-existent device.
6597 When badblocks is given the -vv option, it now updates the block that
6598 it is currently testing on every block.
6600 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6601 currently correctly if PATH wasn't already set.
6603 Shared libraries now built with dependencies. This allows the shared
6604 library files to be used with dlopen(); it also makes the transition
6605 to libc 6 easier, since ld.so can tell which libc a particular shared
6606 library expects to use.
6611 Added new abstraction (defined in dblist.c) for maintaining a list of
6612 blocks which belongs to directories. This is used in e2fsck and other
6613 programs which need to iterate over all directories.
6615 Added new functions which test to see if a contiguous range of blocks
6616 (or inodes) are available. (ext2fs_*_bitmap_range).
6618 Added new function (ext2_inode_has_valid_blocks) which returns true if
6619 an inode has valid blocks. (moved from e2fsck code).
6621 Added new function (ext2fs_allocate_tables) which allocates the
6622 meta-data blocks as part of initializing a filesystem. (moved from
6625 Added a new I/O manager for testing purposes. It will either allow a
6626 program to intercept I/O requests, or print debugging messages to
6627 trace the activity of a program using the I/O manager.
6629 The badblocks_list functions now store the bad blocks in a sorted
6630 order, and use a binary search to speed up badblocks_list_test.
6632 The inode scan function ext2fs_get_next_inode() may now return a soft
6633 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6634 those cases where part of an inode table is missing or there is a bad
6635 block in the inode table.
6637 Added a new function (ext2fs_block_iterate2) which adds new arguments to
6638 the callback function to return a pointer (block and offset) to the
6639 reference of the block.
6641 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6642 application to jump to a particular block group while doing an inode
6645 The badblocks list functions were renamed from badblocks_* to
6646 ext2fs_badblocks_*. Backwards compatibility functions are available
6647 for now, but programs should be modified to use the new interface.
6649 Some of the library functions were reorganized into separate files to
6650 reduce the size of some programs which statically link against the
6653 Put in some miscellaneous fixes for the Alpha platform.
6656 E2fsprogs 1.06 (October 7, 1996)
6657 ================================
6659 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6660 smash the backup copies in ext2fs_close(). (The problem was that when
6661 e2fsck -p discovered the problem, while it was closing the filesystem
6662 and exiting, it was also blowing away the backup superblocks on the
6663 disk, which was less than friendly.) We now make it the case that we
6664 only write out the backup superblock and the back block descriptors if
6665 the filesystem is completely free from problems.
6667 Fixed a bug in block_interate in the lib/ext2fs library which caused
6668 e2fsck to fail on GNU Hurd-created filesystems.
6670 Add support for Linux/FT's bootloader, which actually uses
6671 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6674 Add support for the "A" (no atime update) attribute. (Note: this
6675 attribute is not yet in production kernels.)
6677 The test suite is not automatically run when doing a "make all" from
6678 the top level directory. Users should manually run "make check" if
6679 they wish to run the test suite.
6681 Upon a preenhalt(), make the printed message more explicit that
6682 running e2fsck "MANAULLY" means without the -p or -a options.
6684 In e2fsck, if a disconnected inode is zero-length, offer to clear it
6685 instead of offering to connect it to lost+found.
6687 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6688 e2fsck to be run over it, change e2fsck to explicitly display this
6691 For dumpe2fs and e2fsck, cause the -V option to print out which
6692 version of the ext2fs library is actually getting used. (This will
6693 help detect mismatches of using a 1.06 utility with a 1.05 library,
6699 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6700 the naming convention.
6702 In ext2fs_initialize(), make sure the description for the inode bitmap
6703 is correctly initialize.
6705 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6707 E2fsprogs 1.05 (September 7, 1996)
6708 ==================================
6710 Add support for new fields in the ext2 superblock --- volume name,
6711 volume UUID, and last mounted field. Dumpe2fs displays these fields,
6712 tune2fs and mke2fs allows you to set them. E2fsck will automatically
6713 generate a UUID for those volumes that don't have them.
6715 Put in support for e2fsck to recognize HURD specific ext2 features ---
6716 most notably, the translator block. The e2fsprogs tools will now use
6717 the creator_os field in the superblock to correctly handle different
6718 OS-specific variants of the ext2 filesystem.
6720 E2fsck now fixes inodes which have a the deletion time set, but which
6721 have a non-zero i_link_count field by offering to clear the deletion
6722 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6723 ext2 kernel behavior) and offered to unlink the file.
6725 If e2fsck sets the clean bit, but nothing else, set the exit code
6726 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6727 set the filesystem valid bit when it was previously cleared. :-) This
6728 was needed to make the HURD fsck driver happy.
6730 If the user refuses to attach an unattached inode, e2fsck will no
6731 longer set the inode's link count. Otherwise, the inode would end up
6732 getting marked as unused, which might cause loss of data later.
6734 Make the message issued by e2fsck when the superblock is corrupt less
6735 confusing for users. It now mentions that another reason for the
6736 "corrupt superblock" message might be that the partition might not be
6737 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6739 Make the libext2 library more robuest so that e2fsck won't coredump on
6740 an illegal superblock where the blocksize is zero. (f_crashdisk is
6743 By default, create filesystems where the default checkinterval is 6
6744 months (180 days). Linux servers can be robust enough that 20 reboots
6745 can be a long, long time.
6747 Added configure flag --enable-old-bitops, which forces the bitops to
6748 use the old (native) bitmask operations. By default on the sparc
6749 platform, the standard ext2 bit ordering is now used.
6751 Added a new feature to e2fsck to byte-swap filesystems; this can be
6752 used to convert old m68k filesystems to use the standard byte-order
6753 storage for the superblock, inodes, and directory blocks. This
6754 function is invoked by using the '-s' option to e2fsck.
6756 Debugfs's "dump" command has been enhanced so that it writes out the
6757 exact size of the file so that the nulls at the end of the file are
6758 eliminated. The command also accept a new "-p" option which will
6759 attempt preserve to preserve the ownernship, permissions, and
6760 file modification/access times.
6762 Debugfs has two new options, -f and -R. The -R option allows the user
6763 to execute a single debugfs command from the command line. The -f
6764 option allows the user to specify a "command file" containing debugfs
6765 commands which will get executed.
6767 Dumpe2fs now pretty prints the check interval, instead of just
6768 printing the check interval as a number of seconds.
6770 Fix bugs in debugfs: the params command when no filesystem is opened
6771 no longer causes a core dump. It is now possible to unlink a file
6772 when a pathame containing a '/' is specified.
6774 Tune2fs has a new -C option which sets the number of times the
6775 filesystem has been mounted.
6777 Fix the chattr '-v' option so that it actually works. Chattr was
6778 being buggy about the -v option parsing.
6783 The directory lib/uuid contains a set of library routines to generate
6784 DCE compatible UUIDs.
6786 Extended ext2fs_namei() to handle symbolic links. Added new function
6787 ext2fs_nami_follow() which will follow last symbolic link in the case
6788 where the pathname points to a sym link.
6790 The ext2fs_block_iterate function will now return the HURD translator
6791 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6792 iterator to return data blocks only. The ext2fs.h file now defines
6793 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6794 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6795 count field of the iterator callback function.
6797 The test script driver now takes an optional second argument, which is
6798 the test case to be run. This allows you to run a test case without
6799 needing to run the entire test suite.
6801 On Linux ELF systems, install the .so files in the correct places
6802 (/usr/lib). The .so files must be stored in the same directory as the
6805 Fixed miscellaneous HURD compilation issues with header file being
6806 included in the right order.
6808 Fixed debugfs so that it resets optind to zero, not one, since setting
6809 optind to zero is more correct.
6812 E2fsprogs 1.04 (May 16, 1996)
6813 =============================
6815 First "official" (1.03 was a limited release only) to support building
6816 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6819 This package includes a RPM specs file, that it can be built using the
6820 RedHat Package Manager.
6822 E2fsck now prints a hint that if there are lots of incorrectly located
6823 inode bitmaps, block bitmaps, and inode table blocks, the user might
6824 want to try using e2fsck -b 8193 first, to see if that fares any
6827 For ext2 filesystem written with the hurd, debugfs will now print out
6828 the translator field when printing an inode structure.
6830 Lots of miscellaneous linking/installation cleanups:
6832 Libraries are now linked using a relative pathname, instead of
6833 relying on -L working correct. It doesn't, in many cases, including
6834 current versions of GNU ld. This guarantees that the build tree is
6835 linking with the right libraries, instead of the ones installed in
6838 Header files, man pages, and the et/ss shell scripts are now
6839 generated using a custom substitution script, instead of relying on
6840 the configure script. This prevents needless recompilation of
6841 files; in addition, the custom substitution script is much faster.
6843 e2fsck may now be linked dynamically, by using the
6844 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6845 since it increases e2fsck's dependence on other files, but some
6846 people need to save disk space, and other critical programs on their
6847 systems were being linked dynamically anyway.
6849 Programs such as fsck which didn't need to be linked against
6850 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6851 only link against libraries they actually need. Otherwise, those
6852 programs would require the presense of libraries that otherwise
6853 could be removed from a rescuse diskette.
6855 The ss include files are now installed correctly so they can
6856 actually be used by another package.
6858 If the profiling libraries are built, they are now installed on a
6859 "make install-libs".
6862 E2fsprogs 1.03 (March 27, 1996)
6863 ===============================
6865 Change the m68k bit numbering for bitmasks to match the bit numbering
6866 used by all other ext2 implementations. (This change was requested by
6867 the m68k kernel development team.)
6869 Support (in-development) filesystem format revision which supports
6870 (among other things) dynamically sized inodes.
6872 Fixed a bug in the ext2 library so that an intelligent error is
6873 returned if mke2fs is run with a ridiculously small number of blocks
6876 Fixed a bug in the ext2 library which required that the device be
6877 openable in read/write mode in order to determine its size. This
6878 caused e2fsck -n to require read/write access when it was not
6879 previously necessary.
6881 Fixed a bug in e2fsck which casued it to occasionally fail the test
6882 suite depending on which version of the floating point library it was
6885 Fixed a bug in e2fsck so that it now halts with a fatal error when
6886 certain superblock consistency checks fail. Previously it continued
6887 running e2fsck, with some potential confusing/damaging consequences.
6889 Added new flag to fsck which allows the root to be checked in parallel
6890 with other filesytems. This is not the safest thing in the world to
6891 do, but some system administrators really wanted it.
6893 Fixed -Wall flames in lib/ss.
6896 E2fsprogs 1.02 (January 16, 1996)
6897 =================================
6899 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6901 Change e2fsck to print statistics of how many non-contiguous files are
6902 on the system. Note that a file which is larger than 8k blocks, it is
6903 guaranteed to be non-contiguous.
6905 In mke2fs, print a warning message if a user tries to format a whole
6906 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6907 whole disk, the -F (force) option forces mke2fs to format a whole disk
6910 Fix a bug in fsck where in some cases it might start checking
6911 partitions in the next pass before it finishes checking partitions in
6912 the current pass. This still won't cause two partitions on the same
6913 disk will be checked, so it's rarely a problem in real life.
6915 Patch lsattr so that it won't hang when checking a named pipe.
6917 Minor compilation fixes:
6918 * Fix the order of libraries that were linked in debugfs.
6919 * Allow the sources to be compiled with -ansi turned on.
