1 E2fsprogs 1.43-WIP (July 8, 2013) -- 38cc555a5fc
2 =================================
4 Add support for the ext4 metadata checksum feature.
6 Check to make sure file system features which can not be supported by
7 HURD are not enabled if the file system is created to be
14 Reduce the use of libc functions in libext2fs that may not be present
15 in the boot loader environment, at least for those functions that are
16 needed by boot loadsers such as yaboot.
18 Support for the MMP feature can now be disabled at compile time.
21 E2fsprogs 1.42.8 (June 20, 2013)
23 As a part of mke2fs's option parsing cleanup, the use of the -R option
24 will give a warning that it is depreated (it has been so documented
25 since 2005) and -E should be used instead.
27 Mke2fs will not give warnings about the bigalloc and quota options in
30 If an invalid journal size is given to mke2fs, it will now complain
33 Debugfs was erroneously giving spurious error messages for certain
34 extent_inode subcommands which take arguments (split_node,
35 replace_node, and insert_node). This has been fixed.
37 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
38 other programs is used by mke2fs.
40 Change mke2fs so that it does not set the root directory to the real
41 uid/gid of the mke2fs process. Add the extended option root_owner to
42 override this behavior.
44 Fix resize2fs when shrinking file systems to make sure that bitmap
45 blocks aren't left outside the bounds of the shrunken file system.
46 This could happen with flex_bg file systems that were grown using
47 the old online resizing algorithm.
49 E2fsck will now detect and repair corrupted extent trees which contain
50 invalid extents at the end of the extent tree leaf block.
52 E2fsck will now longer complain about zero length extended attribute
55 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
58 Add safety check so tune2fs will not attempt to set the inode size to
59 be larger than the block size.
61 Fix e2fsck so it can check a read-only root file system with an
62 external journal. (Addresses Debian Bug: #707030
64 Fix off-line resizing of file systems with flex_bg && !resize_inode
65 (Addresses Debian Bug: #696746)
67 Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
70 Enhance chattr to allow clearing the extent flag if the kernel allows
71 migrating extent based files to use indirect blocks.
73 Update German translation.
75 Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
78 Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
83 Use secure_getenv() in preference to __secure_getenv().
85 Optimize CPU utilization of ext2fs_bg_has_super().
87 Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
88 SEEK_CUR is used with large files.
90 The ext2fs_read_inode_full() function will no longer use
91 fs->read_inode() if the caller has requested more than the base 128
92 byte inode structure and the inode size is greater than 128 bytes.
94 Fix build failure with --enable-jbd-debug.
96 Clean up filtering of outputs for the regression tests by using a
99 Fix gcc -Wall and clang nits.
102 E2fsprogs 1.42.7 (January 21, 2013)
103 ===================================
105 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
106 quota features are still under development. For more information
108 * https://ext4.wiki.kernel.org/index.php/Bigalloc
109 * https://ext4.wiki.kernel.org/index.php/Quota
111 Add some new options to filefrag from Lustre's patches to e2fsprogs:
112 * add -k option to print extents in kB-sized units (like df -k)
113 * add -b {blocksize} to print extents in blocksize units
114 * add -e option to print extent format, even when FIBMAP is used
115 * add -X option to print extents in hexadecimal format
117 Fix resize2fs so that it can handle off-line resizes of file systems
118 with the flex_bg feature but without a resize_inode (or if we run out
119 of reserved gdt blocks). This also fixes a problem where if the user
120 creates a filesystem with a restricted number of reserved gdt blocks,
121 an off-line resize which grows the file system could potentially
122 result in file system corruption.
124 Fix a resize2fs bug which could cause it to corrupt bigalloc file
125 systems when doing an off-line resize.
127 Further optimize resize2fs so it doesn't use quite as much CPU when
128 resizing very large file systems.
130 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
131 possibly corrupt the file system while resizing 64-bit file systems.
133 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
134 mke2fs crash due to a divide-by-zero if the 64bit file system feature
137 Add better error checking to mke2fs to check for invalid parameters
138 when creating bigalloc file system.
140 When creating bigalloc filesystems, the -g option to mke2fs will now
141 specify the number of clusters per block group.
143 Add to debugfs the functionality to corrupt a specific file system
144 block via the "zap_block" command.
146 Add to debugfs the functionality to print out a hex dump of a block in
147 the file system via the "block_dump" command.
149 Add to debugfs the functionality to manipulate the extent tree
150 directly via the "extent_open" command.
152 Fixed debugfs's mknod command so that it updates the block group
155 Fix e2fsck so it can detect and fix inconsistencies in the interior
156 nodes of an inode's extent tree.
158 Fix a potential memory corruption failure in e2fsck's error path if
159 the call to ext2fs_open2() fails.
161 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
162 resulting file name for the log file is longer than 100 bytes, that it
163 properly handles this situation instead of crashing.
165 E2fsck will now report the amount of memory that it attempted to
166 allocate when a memory allocation request fails, to make it easier to
167 track down the problem.
169 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
172 E2image can now include all data blocks in the e2image output file
173 when the user specifies the -a option.
175 If e2fsprogs is compiled without --enable-quota, make sure that
176 tune2fs can not turn on the feature for new-style quota support, since
177 afterwards, none of the e2fsprogs tools will be willing to touch that
180 Optimize e2fsck's so that it uses much less CPU for large file
181 systems. This can result in significant speedups, especially on
182 CPU-constrained systems. This was primarily done by optimizing
183 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
185 Fix debugfs's htree command so that all its messages are sent through
188 Fixed debugfs's "dump_file" and "cat" functions work correctly
189 on file systems whose block size is greater than 8k.
191 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
192 less memory. (Addresses Google Bug: 7269948)
194 Update the spd_readdir.c file in the contrib directory to include some
195 additions which were made in 2008 that didn't get folded into the
196 version which we checked into the e2fsprogs source tree. These
197 enhancements include thread safety, support for readdir64_r(), and
198 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
200 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
203 Add a command to debugfs to create symlinks.
205 Document the bigalloc feature in the mke2fs man page. (Addresses
214 Fix a spelling typo in the libext2fs texinfo documentation.
216 Change the output from "make check" so that tools such as emacs's "M-x
217 compile" does not mistake the output as containing a compiler error.
219 Export two new functions from libext2fs: ext2fs_extent_node_split()
220 and ext2fs_extent_goto2().
222 The ext2fs_extents_fix_parents() was fixed so it does not modify the
223 location of the extent handle if its current location is at an
224 interior node, rather than a leaf node of an inode's extent tree.
226 Add a regression test to assure that e2fsck can correctly fix an
227 inconsistent interior node in an inode's extent tree.
229 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
230 correctly support bigalloc file systems which use store block usage
231 information in units of clusters.
233 Fixed the help text in the configure script for --enable-quota.
235 The m68k-specific bitops code has been removed since they were
236 incorrectly treating bit numbers with the high bit set as signed
237 integers. Furthermore, modern compilers do a good enough job
238 optimizing the generic code there is no point in having the m68k
239 specific asm statements.
241 Fixed how we link the test programs so they always use the static
242 libraries, so that we test using the libraries which we have just
245 Update config.guess and config.sub to the latest versions from the GNU
248 Fixed the com_err.texinfo file so that it can produce a valid
249 postscript/pdf printed output.
251 Add a regression test which checks debugfs's ability to create
252 symlinks, named FIFO's, and device nodes.
254 Add a function ext2fs_symlink(), which creates symlinks to the
257 Add debugging code so we can test old kernel interfaces for online
258 resize to resize2fs. This backwards compatibility checking is keyed
259 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
260 test the functionality of the kernel's older resize ioctls without
261 needing to install an old version of resize2fs, and to also test a
262 modern resize2fs's ability to work with older kernels without having
263 to install an older version of the kernel.
266 E2fsprogs 1.42.6 (September 21, 2012)
267 =====================================
269 When mke2fs creates file systems with lazy itable initialization, the
270 progress updates for writing the inode table happens so quickly that
271 on a serial console, the time to write the progress updates can be the
272 bottleneck. So mke2fs will now only update its progress indicators
275 Resize2fs will skip initializing the inode tables if the kernel
276 supports lazy_itable_init, which speeds up growing off-line growth of
277 uninit_bg file systems significantly. Resize2fs will now also
278 correctly set the itable_unused field in the block group descriptor to
279 speed up the first e2fsck after the file system is grown.
281 Resize2fs has been fixed so that on-line resizing of meta_bg file
282 systems work correctly. This is needed to grow file system which are
285 Resize2fs will now correctly handle resizing file systems to 16TB on
286 32-bit file systems when "16TB" is specified on the command line.
288 Fix mke2fs so that it will be careful to set the reserved blocks ratio
289 larger than 50%; this can happen when creating small file systems and
290 when the last block group is dropped because there are not enough
291 blocks to support the metadata blocks in the last block group.
293 Fixed spelling mistake in debugfs's help message.
295 Fixed a potential seg fault in e2fsck when there is an I/O error while
296 reading the superblock.
298 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
300 Updated/fixed various man pages. (Addresses Sourceforge Bug:
306 The configure option --enable-relative-symlink was broken so that it
307 needed to be --enable-symlink-relative-symlinks. We will support both
308 for at least two years, but then the worng configure option will be
311 Fixed a regression introduced in 1.42.5 so the link order for
312 e2fsprogs' libraries will be correct for both static and shared
313 linking. (Addresses Sourceforge Bug: #3554345)
315 Add support for e2fsprogs to be compiled using clang/LLVM.
317 Fix portability problems on non-Linux systems: avoid compile failures
318 on systems that don't have malloc.h
320 Fix f_mmp regression test suite so that debugfs gets killed if the
325 E2fsprogs 1.42.5 (July 29, 2012)
326 ================================
328 Fixed a bug with mke2fs where if there is only 8 inodes per block
329 group, the calculation of the number of uninitialized inodes in the
330 first block group would go negative. This resulted in "mke2fs -N 256
331 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
332 would run out of space. (Addresses Sourceforge Bug: #3528892)
334 Fixed a bug in how e2fsck would uniquify directory entry names.
335 (AddressesSourceforge Bug: #3540545)
337 Previously, e2fsck would only allow a mounted file system to be
338 checked if it was the root file system and it was mounted read-only.
339 Now it will allow any file system mounted read-only to be checked if
340 the -f option is specified. This makes it easier to test how e2fsck
341 handles checking file systems which are mounted without having to test
342 on the root file system.
344 Fixed a problem if e2fsck where if the root file system is mounted
345 read-only, e2fsck would not clear an error indication in the journal
346 superblock. Combined with a kernel bug, this would cause the e2fsck
347 to check the file system after every single boot.
349 The e4defrag program can now handle device symlinks, such as
350 /dev/mapper/testvg-testlv, instead of insisting on a less
351 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
354 Fixed filefrag so it will not crash with a segfault on files from a
355 virtual file system such as /proc. (e.g., "filefrag
358 Fixed filefrag so that it correctly reports the number of extents.
359 (Addresses Red Hat Bugzilla: #840848)
361 Fixed a file descriptor leak in logsave which could cause it to hang.
362 (Addresses Debian Bug: #682592)
364 Fixed e2fsck so that the file system is marked as containing an error
365 if the user chooses not to fix the quota usage information.
367 Fixed tune2fs so that it correctly removes the quota feature when the
368 last quota inode is removed.
370 Fix tune2fs so that after removing a quota inode, the block bitmap is
371 updated; otherwise, e2fsck would complain after running 'tune2fs -O
374 Fix tune2fs so that when converting a file system from using legacy
375 quota files to the new quota file system feature with hidden quota
376 files, the accounting for these files is handled correctly so that
377 e2fsck doesn't complain.
379 Improved e2fsck's verbose reporting statistics, and allow the more
380 verbose reporting to be enabled via /etc/e2fsck.conf.
382 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
384 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
390 Fixed portability problems on other operating systems (e.g., Hurd and
391 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
393 Make sure that shared libraries link with the shared libraries built
394 in the build tree, instead of the system provided libraries.
395 Previously, libraries and executables were linked with the system
396 libraries if present, and possibly using static archives instead of
397 shared libraries. This was also problematic since if libext2fs.so is
398 linked with a static libcom_err.a from system, the build system would
399 attempt to link without -lpthread. (Addresses Sourceforge Bug:
403 E2fsprogs 1.42.4 (June 12, 2012)
404 ================================
406 Fixed more 64-bit block number bugs (which could end up corrupting
407 file systems!) in e2fsck, debugfs, and libext2fs.
409 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
410 not properly propagating the journal's s_errno field to the superblock
411 field; it was not checking this field if the journal had already been
412 replayed, and if the journal *was* being replayed, the "error bit"
413 wasn't getting flushed out to disk.
415 Fixed a false positive complaint by e2fsck if all of the extents in
416 the last extent tree block are uninitalized and located after the end
417 of the file as defined by i_size.
419 The dumpe2fs will now display the journal's s_errno field if it is
420 non-zero, and it will also display the journal's 64-bit feature flag
423 Fix e2fsck so that it always opens the device file in exclusive mode
424 when it might need to modify the file system, and never if the -n
425 option is specified. (Previously, there were a few corner cases where
426 it might get things wrong in either direction.)
428 E2fsck now correctly truncates or deallocates extent-mapped inodes on
429 the orphan list. The root cause was a bug in libext2fs's block
430 iterator which could end up skipping an extent when the last block in
431 an extent is removed, causing the current extent to be removed from
434 E2fsck now correctly sets the global free block and inode counts when
435 truncating or removing inodes on the orphan list in preen mode.
436 Previously, it would leave these values would be set incorrectly,
437 which is largely a cosmetic issue since the kernel no longer pays
438 attention to those fields, but it can cause spurious complaints in
439 subsequent e2fsck runs.
441 Fix i_blocks accounting when the libext2fs library needs to add or
442 remove an extent tree block on bigalloc file systems.
444 The lsattr and chattr programs now support the No_COW flag for the
447 Debugfs now interprets date strings of the form @ddd as ddd seconds
448 after the beginning of the epoch. This is handy when setting an inode
449 number into the d_time field when debugging orphan list handling.
451 Fix a precedence bug with built-in quota support which might result in
452 e2fsck paying attention to the quota inode field even if the built-in
453 quota feature flag is not set. Fortunately, in practice that
454 superblock field should be zero for non-built-in quota file systems,
455 so it's unlikely this bug would have caused problems.
457 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
463 The regression test suite can now run the integration tests in the
464 tests directory in parallel, via "make -jN check".
466 Add new test, f_zero_extent_length which tests e2fsck's handling of
467 the case where all of the extents in the last extent tree block are
468 uninitialized extents after i_size.
470 Add a new test, f_jnl_errno, which checks handling of an error
471 indication set in the journal superblock.
473 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
476 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
477 tests e2fsck's handling of orphan inodes in preen mode, and truncation
478 of extent inodes on the orphan list.
480 Fixed more OS X portability issues.
483 E2fsprogs 1.42.3 (May 14, 2012)
484 ===============================
486 Fix a bug in the Unix I/O manager which could cause corruption of file
487 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
488 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
489 dumpe2fs to incorrectly display block numbers > 32-bits.
491 Improve the support for integrated quota files (where quota is a first
492 class supported feature using hidden files in the ext4 file system).
493 Previously the quota file was getting rewritten even when it was not
494 necessary, and e2fsck would erroneously try to hide quota files which
497 Quiet complaints in e2fsck when the total free blocks or inodes are
498 incorrect in the superblock after an system crash, since we don't
499 update nor depend on the superblock summaries at each commit boundary.
501 Fixed a regression introduced in 1.42.2 which would cause applications
502 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
503 would were still using the legacy 32-bit bitmaps) to crash. This was
504 due to missing 32-bit compat code in side the function
505 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
508 Fix a bug which would cause mke2fs to fail creating the journal if
509 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
512 Updated/fixed various man pages.
514 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
517 Fixed various Debian Packaging issues.
523 Change the nonsensically wrong types in the function signature of the
524 inline function ext2fs_find_first_zero_block_bitmap2(). This was
525 caused by a cut and paste error; fortunately no code in e2fsprogs used
526 this inline function, and there are any users of this functions
527 outside of e2fsprogs.
529 Add support for systems which have valloc(), but which do have
530 posix_memalign() nor memalign() (such as MacOS 10.5).
532 Refactor and clean up the allocation of aligned buffers for Direct I/O
533 support. Previously some allocations were requesting a greater
534 alignment factor that what was strictly necessary. Also optimize
535 reading and writing bitmaps using Direct I/O when the size of the
536 bitmap did not fully cover the file system blocksize.
538 Reserve the codepoints for the INCOMPAT features LARGEDATA and
541 Improved the regression test suite by adding some new integration
542 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
543 jbd2 format, as well as f_eofblocks which tests the new handling of
544 uninitialized and initialized blocks beyond i_size. Also add a new
545 unit test which verifies 32-bit bitmaps support and the new
546 find_first_zero primitives.
548 Add a few dependencies to fix parallel (make -j) builds.
550 Removed bash'isms which were breaking the regression test suite on
551 systems where /bin/sh is not bash.
553 The config.guess and config.sub have been updated to the 2012-02-10
556 Fix a portability problem caused by assuming the present of mntent.h
557 means that setmntent() exists. Instead, explicitly test for this in
558 the configure script.
560 If the sys/signal.h header file does not exist, don't try to include
561 it, since it's not available on all systems.
563 Add support for systems that do not support getpwuid_r()
565 The configure script now supports a new option,
566 --enable-relative-symlinks, which will install relative symlinks for
567 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
569 When building BSD shared libraries make sure the LDFLAGS variable is
570 passed to the linker. Fixing this allows, for example, e2fsprogs to
571 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
574 Fix gcc -Wall nitpicks
577 E2fsprogs 1.42.2 (March 27, 2012)
578 =================================
580 The resize2fs program uses much less CPU and is much faster for very
581 large file systems. (Addresses Debian Bug: #663237)
583 The seti and freei commands in debugfs can now take an optional length
584 argument to set and clear a contiguous range of inodes.
586 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
587 plan to remove support for it from the kernel file system driver. It
588 really wasn't very useful and was causing more problems than it
589 solves. Since e2fsck will complain if inodes that should have
590 EOFBLOCKS_FL do not have the flag set, we are going to remove this
591 check from e2fsprogs first, and then only remove the flag from the
594 The mke2fs program can now use direct I/O via "mke2fs -D". This will
595 slow down the mke2fs, but it makes it more polite on a loaded server
596 by limiting the amount of memory that gets dirtied by mke2fs when it
597 is using buffered I/O.
599 E2fsck was needlessly closing and re-opening the file system as a side
600 effect of adding Multiple Mount Protection (MMP). This isn't
601 necessary for non-MMP file systems, so drop it.
603 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
604 can more easily diagnose memory allocation failures caused by
605 insufficient memory. E2fsck will now abort if there are memory
606 allocation failures when the file system is initially opened and
607 during the block group descriptor checks. (Addresses Google Bug:
610 If there are incorrect block group checks, e2fsck will now report the
611 incorrect and corrected checksum values.
613 The e2fsck progam can now write log files containing the details of
614 the problems that were found and fixed directly, via configuration
615 parameters in /etc/e2fsck.conf.
617 Added the ability to limit the number of messages reported by e2fsck
618 for a given problem type. This avoids a potential bottleneck if there
619 is a serial console which can cause a boot sequence to take a long
620 time if e2fsck needs to report many, many file system errors.
622 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
623 them to use much less memory for large file systems.
625 The dumpe2fs program will now print the expected block group checksum
626 if it is incorrect. This helps to diagnose problems caused by
627 incorrect block group checksums.
629 E2fsck now checks for extents with a zero length, since the kernel
630 will oops if it comes accross such a corrupted data structure. (See
631 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
633 E2fsck has a number of bugs relating to discard that have been fixed.
634 (1) Fixed a bug which could cause e2fsck to discard portions of the
635 inode table which were actually in use. (2) E2fsck will now avoid
636 using discard if the block device doesn't zero data on discard, since
637 otherwise this could cause problems if the file system gets corrupted
638 in the future. (3) E2fsck will now avoid using discard when it is run
639 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
640 discards in the last block group.
642 E2fsck's CPU utilization in pass 5 has been optimized, which will
643 speed up e2fsck slightly.
645 E2image will now skip copying uninitialized bitmap and inode table
648 Fixed mke2fs -S so it does not corrupt the first block group's
651 E2fsck will now check the new sysfs interface to determine if we are
652 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
654 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
656 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
661 Fixed various portability issues for non-Linux systems, particularly
662 MacOS X, as well as Linux systems running with the just-released glibc
665 Fix file descriptor leak in ext2fs_close() if the file system with
666 uninit_bg is opened read/only with a backup superblock. (Addresses
667 SourceForge Bug: #3444351)
669 Fixed an invalid return in a non-void function in the quota code.
670 (Addresses SourceForge Bug: #3468423)
672 Fixed the debian rules file so that the calls to dpkg-buildflags works
673 when the shell is dash.
675 The debian package build now uses V=1 so that there is more
676 information about potential build failures in debian buildd logs.
678 If the uninit flags get cleared by functions such as
679 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
680 superblock is marked dirty and the block group descriptor checksum is
681 updated if necessary.
683 The debian rules file will now try to load debian/rules.custom of it
684 exists. This flie can skip various builds for speed reasons if there
685 is no need for the e2fsck-static or udeb packages. Available
686 customizations in the rules file includes SKIP_STATIC=yes,
687 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
689 In addition, if the file misc/mke2fs.conf.custom.in exists in the
690 source tree, it will be used instead of the standard misc.conf file in
691 the upstream sources. This makes it easier for Debian-derived systems
692 to distribute a custom mke2fs.conf file without having to worry about
693 merge issues if future versions of e2fsprogs makes changes in the
694 upstream default version of mke2fs.conf.
697 E2fsprogs 1.42.1 (February 17, 2012)
698 ===================================
700 The mke2fs and e2fsck now use significantly less memory when creating
701 or checking very large file systems. This was enabled by adding
702 extent-based bitmaps which are stored using a red-block tree, since
703 block and inode allocations tend to be contiguous.
705 The command mke2fs -S is used as a last ditch recovery command to
706 write new superblock and block group descriptors, but _not_ to destroy
707 the inode table in hopes of recovering from a badly corrupted file
708 system. So if the uninit_bg feature is enabled, mke2fs -S will now
709 set the unused inodes count field to zero. Otherwise, e2fsck -fy
710 after using mke2fs -S would leave the file system completely empty.
712 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
713 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
714 installed an mke2fs binary using that name.
716 The usage and help messages for the -G, -t and -T options in mke2fs
719 If e2fsck needs to use the backup group descriptors, the
720 ext2fs_open2() function clears the UNINIT bits to ensure all of the
721 inodes in the file systems get scanned. However, the code which reset
722 the UNINIT flags did not also recalculate the checksum, which produced
723 many spurious (and scary) e2fsck messages. This has been fixed by
724 resetting cheksums when the UNINIT bits are cleared.
726 Relax a check in e2fsck which required that the block bitmap to be
727 initialized when the inode bitmap is in use. This will allow us to
728 eventually eliminate code from the kernel which forcibly initialized
729 the block bitmap when the inode bitmap is first used, requiring an
730 extra journal credit and disk write. (Addresses Google Bug: #5944440)
732 Make sure rdebugfs (which may be installed setuid or setgid disk) does
733 not honor environment variables if euid != uid or egid != gid.
735 Debugfs's ncheck command has been optimized and now is much more
736 robust with faced with corrupted file systems. The ncheck command
737 also now has a -c option which will verify the file type information
738 in the directory entry to see if matches the inode's mode bits. This
739 is extremely useful when trying to use debugsfs to determine which
740 parts of the file system metadata can be trusted.
742 E2image will try to use ftruncate64() to set the i_size for raw
743 images, instead of writing a single null byte. This avoid allocating
744 an extra block to the raw image, for those file systems and/or
745 operating systems that support this. (Linux does.) In addition, fix
746 a logic bug that caused the file to not be properly extended if the
747 size of the last hole was exactly an multiple of a megabyte.
749 Fixed a bug in resize2fs where for 1k and 2k file systems, where
750 s_first_data_block is non-zero, this wasn't taken into account when
751 calculate the minimum file system size for use with the -M option.
753 Fixed the badblocks program to honor the -s flag when in read-only -t
754 mode. (Addresses Debian Bug #646629)
756 Update Czech, Dutch, French, Polish, and Sweedish translation from the
759 Fixed various Debian Packaging issues so that dpkg-buildflags is used
760 if present, which allows e2fsprogs to be built with security hardening
761 flags. (Addresses Debian Bugs: #654457)
766 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
767 This was only an issue for programs compiled against e2fsprogs 1.41
768 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
771 The libext2fs library now uses sysconf() to fetch the page size, instead
772 of the deprecated getpagesize().
774 The ext2fs_get_pathname() function will return a partial path if an a
775 directory in the path is not a directory, displaying it as an inode
776 number in angle brackets instead of giving up and displaying an error.
777 This is much more helpful when a user is trying to debug a corrupted
780 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
782 Added a new library function, ext2fs_file_get_inode_num(), for use by
785 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
786 file, it actually works.
788 The block iterator now properly honors the BLOCK_ABORT flag for
789 extent-based flags. Previously, it didn't, which generally made code
790 be less efficient, but it could cause bugs in ext2fs_link(), for
791 example, by causing it to insert multiple directory entries.
793 Fixed an (harmless other than causing a compiler warning) use of an
794 uninitialized variable in e2fsck's MMP code.
797 E2fsprogs 1.42 (November 29, 2011)
798 ==================================
800 This release of e2fsprogs has support for file systems > 16TB. Online
801 resize requires kernel support which will hopefully be in Linux
802 version 3.2. Offline support is not yet available for > 16TB file
803 systems, but will be coming.
805 This release of e2fsprogs has support for clustered allocation. This
806 reduces the number of block (now cluster) bitmaps by allocating and
807 deallocating space in contiguous power-of-2 collections of blocks,
808 which are called clustered. This is a file system level feature,
809 called 'bigalloc', which must be enabled when the file system is
810 initially formatted. It is not backwards compatible with older
813 Added support for the Multi-Mount Protection (MMP) feature.
815 E2fsck more efficiently uses scratch files for really big file
816 systems. (This is a feature that has to be turned on explicitly; see
817 [scratch_files] in the e2fsck.conf man page.)
819 Fix a bug in e2fsck where if the free blocks and inodes counts are
820 incorrect, e2fsck would fix them without printing an error message.
821 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
822 any explanation of what was fixed.
824 E2fsck will no longer attempt to clone an extended attribute block in
825 pass1b handling if the file system does not support extended
828 E2fsck will be more careful accidentally asking the user to continue
829 if the file system is mounted, so that an escape sequence won't cause
830 a false positive. (Addresses Debian Bug: #619859)
832 E2fsck now uses less cpu time in pass 5 when large portions of the
833 bitmaps are uninitialized.
835 E2fsck will no longer segault when a corrupted file system has a bad
836 extent, and removing it leads to a block needing to be deallocated.
837 (Addresses SourceForge Bug: #2971800)
839 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
840 and print debugging information to make it easier to find potential
843 E2fsck will check to see if the bad block inode looks insane, and will
844 skip trying to use if it certain fields which should be zero look
845 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
846 to get confused and do more harm than good.
848 If e2fsck modifies certain superblock fields which the kernel doesn't
849 look at, it will now mark the superblock as dirty without marking the
850 file system as changed. This avoids signalling the init scripts that
851 a reboot is necessary, since the kernel isn't going to look at those
852 fields, so it won't care if they have been changed.
854 Fixed a bug in the libext2fs library (in the binary search routine of
855 the icount abstraction) that could (very, very rarely) cause e2fsck to
856 die in the middle of pass 1 or pass 2 processing.
858 E2fsck will not try to do a discard operation if the -n option was
859 specified on the command line.
861 E2fsck now supports an extended "discard" option which will cause
862 e2fsck to attempt discard all unused blocks after a full, successful
865 E2fsck will check for the bad block inode to make sure it looks sane
866 before trusting it, to avoid causing more harm than good to the file
869 E2fsck now returns additional status bits in its exit code if it
870 aborts early in the e2fsck run.
872 E2fsck now correctly calculates the maximum file size in the case of
873 the huge_file file system feature enabled without extents.
875 The mke2fs and e2fsck programs now tries to use the punch hole command
876 as a "discard" when operating on normal files.
878 The e2image program now supports the qcow2 format, which is a more
879 efficient way of capturing file system dumps.
881 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
882 per-device defaults to be specified in the configuration file.
884 Mke2fs now supports the reserved_ratio relation in the [defaults] and
885 [fs_types] section in mke2fs.conf.
887 Mke2fs now creates extent-mapped directories for the root and
888 lost+found directories.
890 Mke2fs will skip zero'ing the journal if the extended option
891 "lazy_journal_init" is specified. This can save a lot of time, but it
892 does add a small amount of risk if the system crashes before the
893 journal is overwritten entirely once. It is epsecially useful for
896 Mke2fs will now create file systems that enable user namespace
897 extended attributes and with time- and mount count-based file
898 system checks disabled.
900 Mke2fs will not set a stride or strip size of one block based on block
901 device attributes obtained from sysfs.
903 Mke2fs now displays a progress report during the discard process.
905 Mke2fs now handles extreme file system parameters correctly which
906 previously caused the inodes per group to drop below 8, leading to a
907 segfault. (The inodes per group must be a multiple of 8, but the code
908 didn't correctly deal with an inodes per group count less than 8.)
910 Mke2fs and tune2fs previously would give an error if the user tried
911 setting the stride and stripe-width parameters to zero; but this is
912 necessary to disable the stride and stripe-width settings. So allow
913 setting these superblock fields to zero. (Addresses Google Bug:
916 Mke2fs now gives a warning if the auto-detected block size exceeds the
919 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
920 is the default), mke2fs will now set the s_max_mnt_count superblock
921 field to -1, instead of 0. Kernels older then 3.0 will print a
922 spurious message on each mount then they see a s_max_mnt_count set to
923 0, which will annoy users. (Addresses Debian Bug: #632637)
925 The default mke2fs.conf now has entries for "big" and "huge", which
926 are needed for very big file systems.
928 The resize2fs program now has support for a new online resize ioctl
929 that can support file systems > 16TB, once it arrives in v3.x kernels.
931 Fixed bug which caused resize2fs to fail when shrinking an empty file
932 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
934 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
936 Allow tune2fs to remove external journals if the device can not be
939 Debugfs's icheck will now correctly find inodes which use the
940 searched-for block as an extended attribute block.
942 Debugfs now has a new "punch" command which remove blocks from the
945 Debugfs now has a new "e2freefrag" command which analyzes the free
946 space fragmentation of the file system, using the same code as the
949 Debugfs now has a "filefrag" command which displays information about
950 a file's fragmentation.
952 Add support to build a metadata-only, read-only, stripped-down version
953 of debugfs called rdebugfs.
955 Fixed a potential stack overrun bug in debugfs.
957 The badblocks program now correctly recovers from I/O errors when
958 direct I/O is being used. The badblocks command now also supports a
959 -B option which forces the use of buffered I/O, and the -v option will
960 provide a more detailed breakdown of read, write, and failed
963 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
965 Added support for journals larger than 2GB.
967 Support using both hard links and symlinks when installing e2fsprogs.
969 Add overflow checking to tune2fs -i's fsck interval, which must fit in
972 The debugfs command now has a new 'blocks' command which prints out
973 data blocks of a particular inode in a format which is useful for
976 Filefrag will report 0 extents correctly in verbose mode. (Addresses
977 RedHat Bugzilla: #653234)
979 Filefrag has been fixed so its -v report prints the correct expected
980 block number (previously there had been an off-by-one error). In
981 addition, it will now display the number of contiguous extents when -v
982 is not specified. This makes it consistent with the number of extents
983 printed when the -v option was specified. In addition, the number of
984 contiguous extents is far more interesting/useful than the number of
985 physical extents for very large files. (Addresses Debian Bug:
988 Logsave's usage message has been fixed. (Addresses Debian Bug:
991 Avoid an infinite loop in ext2fs_find_block_device() if there are
992 symlink loops in /dev caused by a buggy udev.
994 Added a useful "fallocate" program to the contrib directory.
996 Fixed an ABI compatibility problem in libext2fs which broke the dump
997 program. Also added back some macros which dump needed so it could
998 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
1001 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
1002 Debian Bug: #641667)
1004 Added internationalization support for libcom_err error table strings.
1006 Fixed various spelling mistakes found in various output strings found
1007 by I18N translators.
1009 Update translations: French, Chinese, Germany, Indonesian, Swedish,
1010 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
1013 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
1014 #614662, #632169, #641838, #627535, #629355)
1016 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
1022 Initial support for quota as an integrated feature, where the quota
1023 files are hidden system files that are automatically maintained by
1024 e2fsck is present, although disabled by default. It must be enabled
1025 by using the configure option --enable-quota.
1027 Reserved the on-disk fields for the metadata checksum and snapshot
1028 features, which are currently in development.
1030 The ext2fs library now has the new functions ext2fs_punch(),
1031 ext2fs_get_memzero() and ext2fs_file_get_inode().
1033 The ext2fs library now has support for calculating the crc32c checksum
1034 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
1036 The I/O manager now supports the discard operation.
1038 Reserved file system code points for new 1st class quota feature.
1040 Shortened the compilation lines by moving the autoconf defines to
1041 a config.h header file.
1043 Fixed a potential free of an unitialized pointer in
1044 ext2fs_update_bb_inode().
1046 Fixed miscellaneous gcc -Wall and coverity warnings.
1048 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
1050 Fixed a build failure when OMIT_COM_ERR is defined.
1052 Improved error checking and fixed memory leaks caused by error return
1055 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
1056 the fsync() to be skipped.
1058 Added a test for extent-mapped journals by mke2fs and tune2fs.
1060 Added a test for creating a large (over 4GB) journal using mke2fs.
1062 Added a test to make sure the inode size remains constant.
1064 The regression test script now prints the list of which tests failed.
1066 The regression test system now uses /tmp for its scratch files, which
1067 is often a tmpfs mounted file system and hence much faster.
1069 The i_e2image test was fixed so it works with valgrind.
1071 Tests that rely on debugfs are now skipped if debugfs wasn't built.
1073 Fixed the dependencies for "make check" so all required dependencies
1074 are built before running the gression tests.
1076 A link to com_err.h is installed in $(includedir) during a "make install".
1078 The po/*.gmo files are automatically rebuilt if they are missing or
1079 out of date. This helps out Debian packaging.
1081 Allow ext2fs_get_memalign() to compile on systems that don't have
1084 Fixed a namespace leak in libext2fs (tdb_null).
1087 E2fsprogs 1.41.14 (December 22, 2010)
1088 =====================================
1090 Fix spurious complaint in mke2fs where it would complain if the file
1091 system type "default" is not defined in mke2fs.conf.
1093 The resize2fs program will no longer clear the resize_inode feature
1094 when the number reserved group descriptor blocks reaches zero. This
1095 allows for subsequent shrinks of the file system to work cleanly for
1096 flex_bg file systems.
1098 The resize2fs program now handles devices which are exactly 16T;
1099 previously it would give an error saying that the file system was too
1102 E2fsck (and the libext2fs library) will not use the extended rec_len
1103 encoding for file systems whose block size is less than 64k, for
1104 consistency with the kernel.
1109 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
1110 been fixed. (Addresses Sourceforge Bug: #3138115)
1112 The ext2fs_block_iterator2() function passed an incorrect ref_offset
1113 to its callback function in the case of sparse files. (Addresses
1114 Sourceforge Bug: #3081087)
1116 Fix some type-punning warnings generated by newer versions of gcc.
1119 E2fsprogs 1.41.13 (December 13, 2010)
1120 =====================================
1122 E2fsck now supports the extended option "-E journal_only", which
1123 causes it to only do a journal replay. This is useful for scripts
1124 that want to first replay the journal and then check to see if it
1127 E2fsck will now support UUID= and LABEL= specifiers for the -j option
1128 (which specifies where to find the external journal). (Addresses
1131 E2fsck now has support for the problems/<problem code>/force_no
1132 configuration option in e2fsck.conf, which forces a problem to not be
1135 Dumpe2fs will now avoid printing large negative offsets for the bitmap
1136 blocks and instead print a message which is a bit more helpful for
1137 flex_bg file systems.
1139 Mke2fs will now check the file system type (specified with the -t
1140 option) to make sure it is defined in the mke2fs.conf file; if it is
1141 not, it will print an error and abort. If the usage type (specified
1142 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
1143 warning but will continue. (Addresses Debian Bug #594609)
1145 Clarified error message from resize2fs clarifying that on-line
1146 shrinking is not supported at all. (Addresses Debian Bug #599786)
1148 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
1149 displayed. (Addresses Debian Bug #555456)
1151 E2fsck will open the external journal in exclusive mode, to prevent
1152 the journal from getting truncated while it is in use due to a user
1153 accidentally trying to run e2fsck on a snapshotted file system volume.
1154 (Addresses Debian Bug #587531)
1156 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
1159 The tune2fs program can now set the uninit_bg feature without
1162 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
1163 default mount options settings which were added in 2.6.35.
1165 The e2fsck and dumpe2fs programs now support the new ext4 superblock
1166 fields which track where and when the first and most recent file
1167 system errors occurred. These fields are displayed by dumpe2fs and
1168 cleared by e2fsck. These new superblock fields were added in 2.6.36.
1170 Debugfs now uses a more concicse format for listing extents in its
1171 stat command. This format also includes the interior extent tree
1172 blocks, which previously was missing from stat's output for
1175 Debugfs has a new option, -D, which will request Direct I/O access of
1178 Mke2fs will skip initializing the inode table if a device supports
1179 discard and the discard operation will result in zero'ed blocks.
1181 Badblocks will now correctly backspace over UTF-8 characters when
1182 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
1183 Debian Bugs #583782 and #587834)
1185 E2freefrag will now display the total number of free extents.
1187 Resize2fs -P no longer requires a freshly checked filesystem before
1188 printing the minimum resize size.
1190 Fixed a floating point precision error in a binary tree search routine
1191 that can lead to seg fault in e2fsck and resize2fs.
1193 Fixed a bug in e2fsck where if both the original and backup superblock
1194 are invalid in some way, e2fsck will fail going back to the original
1195 superblock because it didn't close the backup superblock first, and
1196 the exclusive open prevented the file system from being reopened.
1198 Fixed a big in e2freefrag which caused getopt parsing to fail on
1199 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
1201 Clarified an mke2fs error message so a missed common in an -E option
1202 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
1203 results in a more understandable explanation to the user.
1205 Mke2fs now displays the correct valid inode ratio range when
1206 complaining about an invalid inode ratio specified by the user.
1208 Mke2fs now understands the extended option "discard" and "nodiscard",
1209 and the older option -K is deprecated. The default of whether
1210 discards are enabled by default can be controled by the mke2fs.conf
1213 Mke2fs's handling of logical and physical sector sizes has been
1214 improved to reflect the fact that there will be some SSD's with 8k and
1215 16k physical sectors arriving soon. Mke2fs will no longer force block
1216 size to be the physical sector size, since there will be devices where
1217 the physical sector size is larger than the system's page size, and
1218 hence larger than the maximal supported block size. In addition, if
1219 the minimal and optimal io size are not exported by the device, and
1220 the physical sector size is larger than the block size, the physical
1221 sector size will be used to set the Raid I/O optimization hints in the
1224 E2fsck will now display a better, more specific error message when the
1225 user enters a typo'ed device name, instead of blathering on about
1226 alternate superblocks.

1244 Add support for Direct I/O in the Unix I/O access layer.
1246 Fixed a memory leak in the Unix I/O layer when changing block sizes.
1248 Fixed minor memory leaks in mke2fs.
1250 Added a new function to the ext2fs library, ext2fs_get_memalign().
1252 The tst_super_size test program will check to make sure the superblock

1265 E2fsprogs 1.41.12 (May 17, 2010)
1266 ================================
1268 Mke2fs now gives a correct error message if the external journal
1269 device is not found. (Addresses Red Hat Bug #572935)
1271 Resize2fs -P will now refuse to print a minimum size if the file
1272 system is not clean. Previously it would go ahead and print a minimum
1273 size anyway, which might not be correct, leading to user confusion.
1275 E2fsck now tests for extents that begin at physical block 0 and
1276 rejects them as invalid. (Addresses Google Bug: #2573806)
1278 Fixed a bug in e2fsck which could cause it to crash when trying to
1279 remove an invalid extent and the block bitmaps hadn't yet been loaded.
1280 (Addresses SourceForge Bug: #2971800)
1282 E2fsck now will completely skip time-based checks if the system clock
1283 looks insane or the option broken_system_clock is set in
1286 E2fsck would previously report an i_blocks corruption for a 4T file
1287 created using posix_fallocate; this bug has been fixed.
1289 E2fsck will now correctly mark a sparse journal as invalid and will
1290 delete and recreate the journal to address the problem.
1292 E2fsck would previously incorrectly ask the user whether she would
1293 like to abort the file system check after finding a problem --- and
1294 then abort regardless of the user's answer. This is annoying, and
1297 E2fsck can now continue even if it fails to recreate the resize
1298 inode; previously it would just abort the file system check
1301 E2fsck could potentially remove directory entries for inodes found in
1302 the unused region of the inode table; this would generally happen on
1303 ext4 file systems that do not use journaling. This bug has been fixed
1304 by not clearing these directory entries once it has been established
1305 that bg_unused_inodes may not be trustworthy; once pass #2 has been
1306 completed, e2fsck will restart the file system check from the
1307 beginning, and then it will be safe to delete any directory entries
1308 pointing to inodes that appear to be deleted. (Addresses Google Bug:
1311 E2fsck will not try to set the block group checksums if the user
1312 cancels the fsck with a control-C. It's a bad idea to set the
1313 checksums if e2fsck hasn't been completed, and it often results an the
1314 error message, "Inode bitmap not loaded while setting block group
1315 checksum info". (Addresses Launchpad Bug: #582035)
1317 The mke2fs program now queries the kernel for the physical as well as
1318 the logical sector size, and will not allow a blocksize below the
1319 logical, and will strongly encourage a blocksize at least as big as
1320 the physical blocksize. This is needed for 4k sector drives that
1321 emulate 512 byte sector sizes.
1323 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
1324 rarely needed, but it is a legal value.
1326 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1327 not needed, and offer to clear it; this is a sign of a kernel bug, but
1328 more importantly, some released kernels may crash when this situation
1329 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
1331 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1332 i_size is correct. (Kernels starting with 2.6.34 will set
1335 The com_err library will now only output ^M (a CR character) when the
1338 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,

1341 Fixed various Debian packaging issues --- see debian/changelog for
1342 details. (Addresses Debian Bugs: #571247, #563487)
1348 The regression test suite now uses its own mke2fs.conf file, so that
1349 downstream distributions want change the mke2fs.conf file which is
1350 distributed in the RPM or dpkg file, without worrying about screwing
1351 up the regression test results.
1353 Always build namei.o so that building with configure --disable-debugfs
1354 works correctly. Long-term, if we care about reduced e2fsprogs
1355 builds, we need a more general solution for deciding what .o files are
1356 needed for a particular build. Given that install floppies are going
1357 (gone?) the way the dodo bird, we probably don't care, though.
1358 (Addresses Sourceforge Bug: #2911433)
1360 Add configure options --enable-symlink-build and
1361 --enable-symlink-install, which allow e2fsprogs be built using
1362 symlinks instad of hard links, and to be installed using symlinks
1363 instead of hard links, respectively. It is useful when the file
1364 system where the build is taking place, or the file system where
1365 e2fsprogs is installed, can't handle hard links for some reason.
1366 (Addresses Sourceforge Bug: #1436294)

1371 E2fsprogs 1.41.11 (March 14, 2010)
1372 ==================================
1374 E2fsck will no longer give a fatal error and abort if the physical
1375 device has been resized beyond 2**32 blocks. (Addresses Launchpad
1378 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
1379 the allocation status of the block <blk>. (Addresses Debian Bug:
1382 E2fsck now prints a much more emphatic and hopefully scary message
1383 when a file system is detected as mounted while doing a read/write
1384 check of the filesystem. Hopefully this will dissuade users from
1385 thinking, "surely that message doesn't apply to *me*" :-(
1387 E2fsck -n will now always open the file system read-only. We now
1388 disallow certain combination of options which previously were manual
1389 exceptions; this is bad because it causes users to think they are
1390 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
1391 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
1393 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
1394 it detected a badly aligned partition. Unfortunately, this broke some
1395 distribution installation scripts, so it now just prints the warning
1396 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
1397 Launchpad Bug: #530071)
1399 Mke2fs would take a long time to create very large journal files for
1400 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
1403 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
1404 2.6.34 kernels to make e2fsck not complain about blocks deliberately

1407 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1408 e2fsck -fD can corrupt non-indexed directories when are exists one or
1409 more file names which alphabetically sort before ".". This can happen
1410 with ext2 filesystems or for small directories (take less than a lock)
1411 which contain filenames that begin with a space or some other
1412 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
1419 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

1428 ====================================
1430 Fix resize2fs bug which causes it to access invalid memory.
1432 Add libss support for libreadline.so.6.
1434 Fix e2fsck's check for extent-mapped directory with an incorrect file
1437 Add new e2fsck.conf configuration option, default/broken_system_clock
1438 to support systems with broken CMOS hardware clocks. Also, since too
1439 many distributions seem to have broken virtualization scripts now,
1440 e2fsck will by default accept dates which are off by up to 24 hours by
1441 default. (Addresses Debian Bugs: #559776, #557636)
1443 Fix a bug where mke2fs may not use the best placement of the inode
1444 table when there is only room for a single block group in the last

1448 of fixing file system problems. This reduces the number of spurious
1449 differences found in pass #5.
1451 E2fsck will no longer rehash directories which fit in a single
1454 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
1455 sparse directories which use extents).
1457 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
1459 Fix a bug in filefrag where on platforms which can allow file systems
1460 with 8k blocks, that it doesn't core dump when it sees a file system
1461 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
1464 E2fsck will correctly fix directories that are have an inaccurate
1465 i_size as well as other problems in a single pass, instead of
1466 requiring two e2fsck runs before the file system is fully fixed.
1468 Fix e2fsck so it will correctly find and detect duplicate directory
1469 entries for non-indexed directories. ( Addresses Sourceforge Bug:

1500 Fix e2fsck's handling of 64-bit i_blocks fields.
1502 E2fsck will now print "Illegal indirect block", "Illegal
1503 double-indirect block", etc., instead of "Illegal block #-1" or
1504 "Illegal block #-2", etc. This makes it easier for users to
1505 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)

1562 E2fsprogs 1.41.9 (August 22, 2009)
1563 ==================================
1565 Fix a bug in e2fsck routines for reallocating an inode table which
1566 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1567 filesystem feature with a relatively rare (and specific) filesystem
1568 corruption. This fix causes e2fsck to try to find space for a new
1569 portion of the inode table in the containing flex_bg, and if that
1570 fails, the new portion of the inode table will be allocated in any
1571 free space available in the filesystem.
1573 Make e2fsck less annoying by only asking for permission to relocate a
1574 block group's inode table once, instead of for every overlapping
1575 block. Similarly, only ask once to recompute the block group
1576 checksums, instead of once for each corrupted block group's checksum.
1578 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1579 not present, and it needs to fall back to using the FIBMAP ioctl.
1581 Fix filefrag to correctly print the number of extents for zero-length
1582 files. (Addresses Debian Bug: #540376)
1584 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1585 to more easily debug the FIBMAP code.
1587 Fixed filefrag for non-extent based files.
1589 Add a new program, e2freefrag, which displays information about the
1590 free space fragmentation in an ext2/3/4 filesystem.
1592 Fix inode resizing via tune2fs -I so that it works correctly in the
1593 face of non-empty bad blocks inodes, and if the filesystem was
1594 formatted using the "mke2fs -E stride=N" option for RAID arrays.
1596 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1597 and corrupt large directories if the directory needs to shrink by more
1598 than one block. (Addresses Debian Bug: #537510)
1600 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1601 last mount times are in the future, they are corrected even if
1602 buggy_init_scripts is set. This is needed because otherwise resize2fs
1603 will refuse to resize the filesystem, even after running "e2fsck -f".
1604 (Addresses Launchpad bug: #373409)
1606 E2fsck will now print much fuller information when the last mount time
1607 or last written time is in the future, since most people can't seem to

1609 failed CMOS/RTS clock battery.

1634 there aren't any free blocks or inodes in the already-used block

1656 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1657 will be careful not to close the file descriptor for its unix domain
1658 socket when it detaches itself from the controlling tty. Also add
1659 safety checks so that if the unix domain socket between the uuid
1660 library and uuidd program is closed for any reason, both the library
1661 and the uuidd will return an appropriate error code instead of looping
1662 in an infinite loop.
1664 The e2croncheck script, which creates an LVM snapshot and then checks
1665 the ext3/4 filesystem via the LVM snapshot, has been added to the

1703 uninitalized data into the portion of the inode beyond the first 128
1704 bytes when operating on inodes mapped via extents; potentially
1705 corrupting filesystems.

1758 E2fsprogs 1.41.6 (May 30, 2009)
1759 ===============================
1761 Fix a critical regression in e2fsck introduced version 1.41.5 which
1762 can undo updates to the block group descriptors after a journal replay.
1764 If e2fsck receives an I/O error while replaying the journal, prompt
1765 the user whether they want to ignore the error or not; if e2fsck is
1766 run in preen mode, force fsck to abort the preen pass.
1768 Fix a bug which would cause e2fsck to core dump if the filesystem
1769 contains a corrupt extent header, and the user declines to clear the
1770 inode. (Addresses Sourceforge Bug: #2791794)
1772 Fix e2fsck to restart only once in the case of multiple block groups
1773 which inodes in use that are in the uninitialized part of the block
1774 group's inode table.
1776 To reduce user confusion, if the /etc/mtab file is missing
1777 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1778 new, explicit error code to indicate this case. This will cause
1779 e2fsck to give a clearer error message when the user is using buggy
1780 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
1783 Fix e2fsck so that if the primary group descriptors are corrupted, but
1784 the backup superblock is entirely invalid, to go back to using (and
1785 fixing) the priary group descriptors instead of completely giving up
1786 on the filesystem. (Addresses Debian Bug: #516820)
1788 Change e2fsck to not abort a preen pass if an inode is found to have
1789 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
1790 kernels (post 2.6.29) will ignore this field. So let's fix it
1791 automatically during the preen pass instead of forcing the user to fix
1792 this up manually. (Addresses Debian Bug: #526524)
1794 Add resource tracking for e2fsck passes 1b through 1d.
1796 Speed up e2fsck by eliminating unnecessary journal checks if the
1797 filesystem is already mounted and doesn't need recovery (since the
1798 kernel would have run the journal when the filesystem was mounted.)
1799 Also speed up e2fsck by avoiding unnecessary block group descriptor
1800 updates in ext2fs_close().
1802 Add support to chattr to migrate inodes from using direct/indirect
1805 Avoid corrupting the filesystem if there is an attempt to shrink a
1806 filesystem using resize2fs smaller than posible by making
1807 ext2fs_set_bmap() more careful not to delete the old block until the
1808 new block can be inserted. In addition, fix a bug in how the minimum
1809 size of the filesystem (plus a safety margin) is calculated, and
1810 modify resize2fs to refuse to shrink the filesystem below that minimum
1811 size without the force flag.
1813 Teach blkid to try to figure out DM device names using take advantage
1814 of information in sysfs when running on kernels (2.6.29 and later)
1815 which provide this information in /sys/block/dm-<N>/dm/name; this is
1816 much faster than scanning for the devncie number in /dev/mapper.
1818 Fix blkid to prefer /dev/mapper/<name> device names instad of the
1819 private /dev/dm-X names.
1821 Add an -a option to debugfs's close_filesys command which writes any
1822 changes to the superblock or block group descriptors to all of the
1823 backup superblock locations.
1825 Add support to the filefrag program to use the FIEMAP ioctl.
1827 Update Chinese translation from the Translation Project.
1829 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
1830 Launchpad Bug: #381854)
1832 Fixed various Debian packaging issues --- see debian/changelog for
1833 details. (Addresses Debian Bug #506064)
1839 Add test code to make sure e2fsck's problem.c doesn't have two problem
1840 codes assigned to duplicate values.
1842 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1843 (Addresses Sourceforge Bug: #2780205)
1845 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1846 function declaration for init_resource_track() and
1847 print_resource_track() when RESOURCE_TRACK is not defined.
1849 The test code which is used to build the tst_csum progam has been
1850 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1851 avoid compile problems caused by not having a prototype for
1852 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
1854 Update the config.guess and config.sub file to the latest from the
1855 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
1856 Debian Bug: #528330)
1858 Add a new function, ext2fs_extent_open2(), which behaves like
1859 pext2fs_extent_open(), but uses the user-supplied inode structure
1860 when opening an extent instead of reading the inode from disk.
1863 E2fsprogs 1.41.5 (April 23, 2009)
1864 =================================
1866 Fix a number of filesystem corruption bugs in resize2fs when growing
1867 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1870 Debugfs can now set i_file_acl_high via the set_inodes_field command,
1871 and print a 64-bit file acl. This is useful for debugging filesystem
1872 corruptions where the high bits of i_file_acl_high are set. E2fsck
1873 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1874 since some Linux kernel versions pay attention to this field even when
1877 Speed up e2fsck when checking clean filesystems by avoiding
1878 unnecessary block reads, and coalescing the block group descriptor
1879 blocks so they are read using a single read operation.
1881 The libuuid library will now close all file descriptors before running
1882 uuidd. This avoids problems when the calling program has open sockets
1883 which then never get closed because uuidd is a long-running helper
1884 daeomn. (Addresses Launchpad bug: #305057)
1886 In order to avoid unnecessary full filesystem checks by e2fsck after
1887 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1888 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
1890 Mke2fs will avoid trying to create the journal when run in
1891 superblock-only mode (mke2fs -S), since the left-over journal in the
1892 inode table will cause mke2fs to fail.
1894 Fix a bug in libext2fs functions that check to see if a particular
1895 device or filesystem image is mounted, which would cause these
1896 functions to report that a file identical to the (relative) pathname
1897 used by a pseudo-filesystem was mounted when in fact it was not.
1899 Update Czech translation from the Translation Project.
1901 Add Chinese (simplified) translation from the Translation Project.
1903 Fix support for external journals (which was broken in e2fsprogs
1906 Fix a regression in debugfs where the "stat" command when no
1907 filesystem was open would cause debugfs to crash with a segmentation
1910 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1911 used to support filesystems without a journal. Update the blkid
1912 library so it understands this.
1914 The blkid library will remove an entry from the blkid cache
1915 representing the entire disk if partitions are found, since presuambly
1916 the device previously had no partition table, but has now transitioned
1917 to using a partition table.
1919 Add a check to mke2fs and tune2fs that the argument to the -m option
1920 (which specifies the reserved ratio) must be greater than zero.
1921 (Addresses Debian Bug: #517015)
1923 Add support for tracking the number kilobytes written to the
1924 filesystem via the superblock field s_kbytes_written. It will be
1925 updated by the kernel as well as by e2fsprogs programs which write to
1926 the filesystem. This is useful for tracking the wear to filesystems
1927 on Solid Sstate Drives.
1929 Fix compatibility issue in the libext2fs info file and makeinfo
1930 version 4.12. (Addresses Red Hat Bugzilla: #481620)
1932 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
1934 Fixed various Debian packaging issues --- see debian/changelog for
1935 details. (Addresses Debian Bug: #506279)
1940 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
1943 Fix various gcc compilation warnings and other programming cleanups.
1944 (Addresses Red Hat Bugzilla: #486997)
1946 Add support for building the blkid command statically.
1948 Add support for disabling the built-in blkid library in favor of a
1949 system-installed blkid implementation via the configure option
1953 E2fsprogs 1.41.4 (January 27, 2009)
1954 ===================================
1956 Fixed a bug which could sometimes cause blkid to return an exit value
1957 of zero for a non-existent device (Addresses Debian Bug: #502541)
1959 Blkid will now recognize ext3 filesystems that have the test_fs flag
1960 set as ext3 filesystems.
1962 The blkid library will now recognize btrfs filesystems and swap
1963 devices currently used by user-level software suspend.
1965 Tune2fs now updates the block group checksums when changing the UUID
1966 to avoid causing e2fsck to complain vociferously at the next reboot.
1968 Tune2fs's inode size resizing algorithms have been fixed so it is not
1969 vastly inefficient for moderate-to-large filesystems, due to some
1970 O(n**2) and O(n*m) algorithms that didn't scale well at all.
1972 Fix tune2fs's inode resizing algorithm so it will not corrupt
1973 filesystems laid out for RAID filesystems; in addition, tune2fs will
1974 refuse to change the inode size for filesystems that have the flex_bg
1975 feature enabled. (This is a limitation in the current implementation
1978 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1979 filesystems with 32-bit block numbers, when the headers for 64-bit
1980 block numbers was added. This regression has been fixed.
1982 Debugfs's ncheck command has been fixed to avoid printing garbage
1983 characters at the end of file names.
1985 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
1986 when shrinking filesystems with uninit_bg feature would not be moved.
1987 In addition, blocks and inode table blocks were not being correctly
1988 freed when shrinking filesystems with the flex_bg feable, which caused
1989 resize2fs -M to fail. Finally, when blocks are moved, make sure the
1990 uninitialized flag in extents is preserved.
1992 Fix bug which caused dumpe2fs to abort with an error if run on a
1993 filesystem that contained an external journal.
1995 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1996 for this in argv[0] to provide better legacy support for these
1997 distributions. This is a practice that should NOT be continued,
2000 Mke2fs now has a new option -U, which allows the user to specify the
2001 UUID that should be used for the new filesystem.
2003 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
2004 minus one block. This allows users who have read that ext3 supports
2005 up to 16TB filesystems and who create a 16TB LVM to not get confused,
2006 since the true limit is really 16TB minus one block.
2008 E2fsck will no longer abort an fsck run if block group has an errant
2011 E2fsck now distinguishes between fragmented directories and fragmented
2012 files in verbose mode statistics and in the fragcheck report.
2014 Fix a bug in e2fsck which casued it double count non-contiguous
2015 extent-based inodes.
2017 E2fsck will leave some slack space when repacking directories to allow
2018 room for a few directory entries to be added without causing leaf
2019 nodes to be split right away.
2021 Fix a bug which caused e2fsck to crash when it comes across a
2022 corrupted interior node in an extent tree with the error message:
2023 "Error1: Corrupt extent header on inode XXXXXX"
2025 E2fsck problem descriptions involving the journal are no longer
2026 referred to as "ext3" problems, since ext4 filesystems also have
2029 Fix a long-standing bug in e2fsck which would cause it to crash when
2030 replying journals for filesystems with block sizes greater than 8k.
2032 Update Catalan translation from the Translation Project.
2034 Fixed various Debian packaging issues --- see debian/changelog for
2035 details. (Addresses Debian Bugs: #503057, #502323, #511207)
2040 Fix build of e2fsck.profiled, and add support for building profiled
2041 binaries in the misc directory if configured with --enable-profile.
2043 The ext2fs_open() function now performs more sanity checks on the
2044 superblock to avoid potential divide by zero errors by other parts of
2047 The ext2fs_read_inode_full() function now has a safety check to avoid
2048 a segmentation fault on corrupted filesystems.
2050 The ext2fs_new_inode() function now has a sanity check so that if the
2051 s_first_inode field in the superblock is insane, it will return
2052 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
2054 To avoid segmentation faults, ext2fs_block_alloc_stats() and
2055 ext2fs_inode_alloc_stats() now validates the passed inode or block
2056 number to avoid overrunning an array boundary.
2058 Various signed/unsigned errors for variables containing block numbers
2061 Accomodations for gcc's stupidity in not realizing that constant
2062 strings that do not contain a '%' character are safe to use in format
2063 strings have been made so that distributions that want to compile
2064 e2fsprogs with -Werror=format-security have an easier time doing so.
2066 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
2068 Added the utility make-sparse.c to the contrib directory.
2070 The ext2fs_block_iterate2() function now reflects errors from
2071 ext2fs_extent_set_bmap() to the caller, if the callback tries to
2072 change a block on an extent-based file, and ext2fs_extent_set_bmap()
2073 fails for some reason (for example, there isn't enough disk space to
2074 split a node and expand the extent tree.
2076 The ext2fs_block_iterate2() function will preserve the uninit flag in
2077 extents when the callback function modifies a block in an extent-based
2080 E2fsck will now flag filesystems that have an insane s_first_ino field
2081 in their superblock, and attempt to use a backup superblock to repair
2085 E2fsprogs 1.41.3 (October 12, 2008)
2086 ===================================
2088 E2fsck has been fixed so it prints the correct inode number for
2089 uinit_bg related problems.
2091 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
2092 is available on linux. This can be disabled via a configuration
2093 option in /etc/e2fsck.conf.
2095 Fix a file descriptor leak in libblkid when checking to see if an ext4
2096 or ext4dev module exists.
2098 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
2099 while trying to close a filesystem can lead to infinite loops.
2100 (Addresses Red Hat Bugzilla #465679)
2102 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
2103 will cause resize2fs to drop into an infinite loop. (Addresses Red
2104 Hat Bugzilla: #465984)
2106 Add a check in the Unix I/O functions in libext2fs so that when a
2107 device is opened read/write, return an error if the device is
2108 read-only using the BLKROGET ioctl.
2110 Fix debugfs's ncheck command so that it prints all of the names of
2111 hardlinks in the same directory.
2113 Fix a bug in libblkid so it correctly detects whether the ext4 and
2114 ext4dev filesystems are available, so that the ext4dev->ext4
2115 fallback code works correctly.
2120 Fix a parallel build problem by making sure util/subst is built before
2121 trying to build the lib/et directory. (Addresses Sourceforge Bug:
2124 Updated "make depend" information for crc16.o
2127 E2fsprogs 1.41.2 (October 2, 2008)
2128 ==================================
2130 Fix e2fsck's automatic blocksize detection. This fixes a regression
2131 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
2132 specifies a block number using the -b option if the blocksize option
2133 isn't also specified using -B. Unfortunately, users very commonly
2134 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
2135 superblock; in fack e2fsck will often suggest this kind of command
2138 Enhance the debugfs's "ncheck" command so it will print all of the
2139 pathnames for the specified inodes. (Previously, in some cases ncheck
2140 might not print a pathname for an inode at all if some of the other
2141 inodes had multiple hard links.)
2143 Enhance debugfs's "hash" command so the hash seed can be specified via
2144 a command-line option. In addition, allow the hash algorithm to be
2145 specified by name instead of just by number.
2147 Fix e2fsck so that we don't accidentally print the translation file's
2148 header when asking the user a custom question so there is no prompt
2149 defined for a particular problem record. For example, the question
2150 "Run journal anyway" will get the PO header tacked on because e2fsck
2151 erroneously passed the null string to _(). (Addresses Launchpad Bug:
2154 Enhance badblocks so that it can test a normal file which is greater
2157 Enhance the badblocks command so that it displays the time and
2158 percentage complete when in verbose mode. (Addresses Debian Bug:
2161 Fix a potential memory leak in a error handling path in debugfs's
2164 Fix a potential memory corruption problem if a memory allocation fails
2167 Fix the usage message for debugfs's logdump command to be consistent
2168 with its man manpage.
2170 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
2171 and Sweedish translation from the Translation Project.
2173 Add documentation for the file I/O functions to the libext2fs.texinfo
2174 file. (Addresses Debian Bug: #484877)
2176 Update and clarified various man pages. (Addresses Launchpad Bug
2177 #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
2179 Fixed various Debian packaging issues --- see debian/changelog for
2180 details. (Addresses Debian Bug: #497619)
2185 Fix a potential file descriptor leack in libcom_err by setting the
2186 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
2189 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
2190 has been carrying a patch for a long time to prevent a largely
2191 theoretical race condition if a multi-threaded application adds and
2192 removes error tables in multiple threads. Unfortunately SuSE's
2193 approach breaks compatibility by forcing applications to link and
2194 compile with the -pthread option; using pthread mutexes has
2195 historically been problematic. We fix this by using sem_post/sem_init
2198 Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
2199 Sourceforge Bug: #2087502)
2201 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
2202 libraries when using ELF shared libraries.
2204 Fix ELF shared library when building on systems that don't already
2205 have the e2fsprogs shared libraries already installed. (Addresses
2206 Sourceforge Bug: #2088537)
2208 Fix the pkg-config files so they work correctly when linking with
2209 static libraries and fix the include directory so programs don't have
2210 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
2211 instead. (Addresses Sourceforge Bug: #2089537)
2213 Make sure ext2fs_swab64() is compiled for all platforms, and not just
2214 for x86. (Addresses Debian Bug: #497515)
2216 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
2217 non-x86 platforms. (They had been removed for x86 earlier.)
2219 Fix diet libc compilation support, which had bitrotted due to lack of
2220 TLC. Fixing this improves general portability.
2222 When installing the link library when using ELF shared libraries,
2223 avoid using absolute pathnames if the link library and the shared
2224 library are installed in the same directory. (Addresses Sourceforge
2227 Fix gen-tarball so it will work even if the top-level directory has
2228 been renamed to something other than "e2fsprogs". Also make
2229 gen-tarball print the size of the resulting tar.gz file.
2232 E2fsprogs 1.41.1 (September 1, 2008)
2233 ====================================
2235 Many people are forgetting to update their mke2fs.conf file, and this
2236 causes ext3, ext4, and ext4dev filesystems won't get created with the
2237 proper features enabled. We address this in two ways. First, mke2fs
2238 will issue a warning if there is not definition for an ext3, ext4, or
2239 ext4dev filesystem and the user is trying to create such a filesystem
2240 type. Secondly, when installing from a source build, "make install"
2241 will provide basic configuration file handling for /etc/mke2fs.conf.
2242 If it exists, and does not mention ext4dev, it will be moved aside to
2243 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
2244 be installed. If the existing /etc/mke2fs.conf file does mention
2245 ext4dev, then "make install" will install official mke2fs.conf file as
2246 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
2247 they should look to see if any changes need to be merged.
2249 The mke2fs program will now create the journal in the middle of the
2250 filesystem, since this minimizes seek times on average for fsync-heavy
2251 workloads. In addition, mke2fs will now create journals using extents
2252 for filesystems that support them. This results in a more efficient
2253 encoding for the journal since it eliminates the need for using
2256 The mke2fs program will avoid allocating an extra block to the
2257 journal. (Addresses Sourceforge Bug: #1483791)
2259 Mke2fs will correctly enforce the prohibition against features
2260 (specifically read-only features) in revision 0 filesystems. (Thanks
2261 to Benno Schulenberg for noticing this problem.)
2263 Mke2fs previously would occasionaly create some slightly non-optimally
2264 placed inode tables; this bug has been fixed.
2266 The mke2fs and tune2fs programs now print the correct usage message
2267 describing the maximum journal size. (Addresses Debian Bug: #491620)
2269 Add support for setting the default hash algorithm used in b-tree
2270 directories in tune2fs (from a command-line option) or mke2fs (via
2271 mke2fs.conf). In addition, change the default hash algorithm to
2272 half_md4, since it is faster and better.
2274 The blkid library will now recognize MacOS hfsx filesystems, and
2275 correctly extract the label and uuid for hfs, hfsx, and hfsplus
2276 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
2278 The blkid library has improved detection of JFS and HPFS filesystems.
2279 (Addresses Launchpad Bug: #255255)
2281 The blkid library is now much more efficiently handling devicemapper
2282 devices, mainly by no longer using the devicemapper library. This can
2283 speed up access for systems with a large number of device mapper
2286 Blkid had a number of cache validation bugs in libblkid that have been
2287 fixed. (Addresses Debian Bug: #493216)
2289 Resize2fs will now properly close out the "updating inode references"
2290 progress bar so there is a newline printed before printing the final
2291 "resize is successful" message.
2293 Resize2fs will now correctly handle filesystems with extents and/o
2294 uninitialized block groups correctly when file/directory blocks need
2295 to relocated (i.e., when shrinking a filesystem or if the resize_inode
2296 is not present). To support this, the ext2fs library now supports
2297 initializing inode and block bitmaps that are not yet initialized when
2298 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
2299 addition, e2fs_block_iterate2() can now support changing the location
2300 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
2301 been optimized to avoid creating unnecessary new extents when updating
2302 the location of blocks in the extent tree. This will also help out
2303 e2fsck's recovery of obscurely corrupted filesystems with extents,
2304 when blocks are claimed by multiple inodes.
2306 Add support for on-line resizing ext4 filesystem with the flex_bg
2307 filesystem feature. The method for doing so is not optimal, but to do
2308 a better job will require kernel support.
2310 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
2311 debugfs programs to not be able to read e2image files; the signed
2312 vs. unsigned bug in the code which read bitmaps from the e2image has
2313 been fixed. (Addresses Debian Bug: #495830)
2315 Resize2fs is now correctly managing the directory in-use counts when
2316 shrinking filesystems and directory inodes needed to be moved from one
2317 block group to another. This bug has been around since e2fsprogs
2318 1.26, and is largely harmless, but does cause a filesystem corruption
2319 which will be flagged by e2fsck after the filesystem has been shrunk.
2321 E2fsck will no longer issue spurious complaints about the inode size
2322 caused by very large extent-based files, and by blocks reallocated
2323 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
2324 Kernel Bugzilla: #11341)
2326 Mke2fs will now set the creation timestamp on the lost+found directory
2327 and the root directory. (More generally, all new inodes created using
2328 the ext2fs library will correctly set the creation timestamp.)
2330 E2fsck now correctly calculates ind/dind/tind statistics in the
2331 presence of extent-based files. In addition, "e2fsck -v" will report
2332 statistics of the depth of extent trees in the filesystem. E2fsck can
2333 also give an inode fragmentation report using "e2fsck -E fragcheck"
2334 which can be useful when debugging the kernel block allocation
2337 Fix support for empty directory blocks in ext4 filesystems with 64k
2338 blocksize filesystems.
2340 E2fsck will now print the depth of corrupt htree directories.
2342 Debugfs's htree command now correctly understands extent-based
2343 directories. It will also print out the minor hash as well as the
2346 Debugfs has a new command which will print the supported features of
2347 e2fsprogs, to enable scripts to know whether the installed version of
2348 e2fsprogs can support a specific feature.
2350 Debugfs will now write files using extents for filesystems that
2353 The error message printed by "tune2fs -I" if the inode size was too
2354 small was rather confusing, so it has been improved. Also, we won't
2355 try to create an undo log until we know that command-line-specified
2356 parameters such as "tune2fs -I <inode size>" are valid.
2358 Given some filesystems found "in the wild" that had non-zero block
2359 group checksums even though the uninit_bg/gdt_sum feature was not
2360 enabled, e2fsck would issue spurious error messages. Teach
2361 ext2fs_group_desc_csum_verify() to ignore the block group checksum
2362 entirely if the feature flag is not set. (Addresses Debian Bug:
2365 The blkid program will now print out a user-friendly listing of all of
2366 the block devices in the system and what they contain when given the
2367 -L option. (Addresses Debian Bug: #490527)
2369 The filefrag program now has a more accurate calculation for the
2370 number of ideal extents. (Addresses Debian Bug: #458306)
2372 The test I/O manager is now enabled by default, but its overhead is
2373 only incurred when it would be enabled via the TEST_IO_FLAGS or
2374 TEST_IO_BLOCK environment variables.
2376 Typographical errors in various program strings and usage messages
2377 have been fixed; most of these were pointed out by the e2fsprogs

2403 Sourceforge Bug: #2019287)
2405 The ext2fs_extent_set_bmap() had some bugs when setting the first
2406 block in a file, or when replacing a single block extent. Those cases
2407 fortunately were came up relatively rarely when e2fsck was checking
2408 files, but caused some problems when resize2fs was shrinking

2414 Various ext2fs library functions --- ext2fs_block_iterate2(),

2416 allocated memory to avoid memory leaks in all of their error return
2419 Ext2ed was failing to build because masix support had been removed in
2420 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
2422 The configure script now respects the LDFLAGS environment variable if
2423 it is set when configure is called. (Addresses Sourceforge Feature
2426 Libuuid is now more portable to the Windows platform. (Addresses
2427 Sourceforge Feature Request: #1937287)
2429 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2430 bare echo commands so that configure flags such as --quiet work
2431 correctly. (Addresses Sourceforge Patches: #2058794)
2433 A few uses of sprintf have been removed from the ext2fs library to
2434 make life easier for bootloaders with a limited libc environment.

2442 passed to it earlier, to avoid doing some needless work when it would
2445 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2446 top-level Makefile. That automatic rule is used to better support
2447 SCCS, but it caused problems for a particular niche distribution which
2448 likes to use configure.sh files to store the configure options used to
2449 build a package. Unfortuntaely GNU make will use the configure.sh to
2450 replace the configure script, resulting in a self-inflicted fork bomb
2451 leading to an out-of-memory crash.
2453 To support old GNU C compilers don't use C99/C++ comments, but only
2454 K&R style comments, and don't try to use __builtin_expect if __GNUC__
2455 is less than 3. (__builtin_expect is only supported for gcc versions
2456 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2457 this is an optimization, we only try to use __builtin_expect for gcc 3
2460 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2461 __LITTLE_ENDIAN, which are only defined by glibc's header files and
2462 hence isn't portable.
2464 For the convenience for some distributions that need a static tune2fs,
2465 the Makefile for misc/ now has a tune2fs.static target.
2467 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2468 for extent-based files
2470 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2473 All source files no longer have any trailing white space.
2475 The io_channel_read_blk64() and io_channel_write_blk64() functions are
2476 now functions instead of C preprocessor macros to provide better
2477 forward compatibility.

2484 Fix a parallel build problem in e2fsprogs.
2486 E2fsprogs is now more portable to Solaris.
2487 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
2489 * Scripts do not assume that /bin/true is always in /bin
2490 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2491 * Flush stdio handles before calling setbuf(), since Solaris will
2492 discard any pending output to the stream.
2493 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2494 picky about which C compiler can beused for SUSv3 conformance.
2495 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2496 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2497 Since we need some SUSv3 functions, consistently use SUSv3 so
2498 that e2fsprogs will build on Solaris using c99.
2499 * Solaris C99 does not support varargs C preprocessor macros
2500 * Solaris header files pollute the C namespace if in/netinet.h
2501 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2503 * Solaris ships with a pathetically ancient shell in /bin/sh so we
2504 avoid the use of various more avanced shell constructs such as $().
2506 The "make rpm" command will now take some extra configure optiosn from
2507 the build environment without needing to patch the source tree.
2509 The ext2fs_add_dir_block() function will now grow the dblist more
2510 aggressively as an optimization to avoid copying the array too often.
2512 The e2fsck_write_bitmaps() will write the block and inode bitmaps
2513 together instead of in two passes.
2516 E2fsprogs 1.41 (July 10, 2008)
2517 ==============================
2519 Add support for ext4 filesystem features, in particular extents,
2520 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
2521 support for checking journal checksums. Debugfs will print new
2522 superblock and inode fields that were defined for ext4. For example,
2523 the nanosecond and i_version fields of an inode, and the
2524 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2525 Note: Resize2fs doesn't currently support the combination of flex_bg
2526 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
2528 Tune2fs can support migrating a filesystem from using 128 byte inodes
2529 to 256 byte inodes, so it can take advantage of the full features of
2532 Add support for "undo" support. E2fsck and mke2fs can optionally
2533 record an undo log which can replayed by the program e2undo.
2535 E2fsck could damage a filesystem by trying to relocate inode tables
2536 due to corrupted block group descriptors, where the attempted inode
2537 table relocation would do far more harm than good. E2fsck has been
2538 fixed to detect this these sorts of corrupted block group descriptors
2539 much earlier in e2fsck processing, so it can try to use the backup
2540 superblock and block group descriptors first. This should be a much
2541 better strategy for recovering these types of corrupted filesystems.
2542 (Addresses Sourceforge Bug: #1840291)
2544 E2fsck will display a more understandable message when the last check
2545 field in the superblock is in the future. (Addresses Debian Bug:
2548 E2fsck now performs more extensive and careful checks of extended
2549 attributes stored in the inode.
2551 Enhance mke2fs to print a more explanatory error message when
2552 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
2555 Fix mke2fs to use a default block size of 4k when formatting an
2556 external journal device. This is done by using a fixed filesystem
2557 type list that consists only of the single filesystem type "journal"
2558 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
2559 Debian Bug: #488663)
2561 Speed up how mke2fs writes the journal data blocks by writing the disk
2562 blocks in larger chunks.
2564 Fix blkid handling of stale devices. Fix a bug which could cause a
2565 core dump while garbage collecting the blkid cache, and assure that
2566 blkid_find_dev_with_tag() never returns a non-existent device. Also,
2567 if a filesystem is found at a new /dev location, eliminate any
2568 duplicate stale entries which can not be verified.
2569 (Addresses Debian Bugs: #487758, #487783)
2571 Add more paranoid checks for LVM volumes and swap partitions in
2572 blkid's probe function, to reduce the chances of false positives.
2574 The mke2fs program now has a much more sophisticated system for
2575 controlling configuration parameters of a newly created filesystem
2576 based on a split filesystem and usage type system. The -t option to
2577 mke2fs was a deprecated alias to -c; it now specifies a filesystem
2578 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2579 separated usage list. The filesystem type information and type
2580 information is used to extract configuration parameters from the
2581 /etc/mke2fs.conf file.
2583 The mke2fs program will no longer complain and request the -f option
2584 when the user tries to create a filesystem with greater than 2**31
2587 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2588 adjust the mke2fs.conf file so filesystems for the Hurd are created
2589 with a blocksize of 4096 and inode size of 128, which is all it knows
2590 how to handle. (Addresses Debian Bug: #471977)
2592 Mke2fs will always make sure that lost+found always has at least 2
2593 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2595 Resize2fs will now print the minimum needed filesystem size if given
2596 the -P option, and will resize the filesystem to the smallest possible
2597 size if given the -M option.
2599 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2600 blocks are consumed during an off-line resize.
2602 The "ls" command in debugfs now supports the -p option, which causes
2603 it to quote the filenames so that spaces or tabs in directory entries
2604 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
2605 Sourceforge Feature Request: #1201667)
2607 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
2610 The chattr program will return a non-zero exit code in case of
2611 failures, and error messages can be suppressed with the -f option.
2612 (Addresses Red Hat Bugzilla: #180596)
2614 Fix a bug in badblocks which caused it to overrun an array and likely
2615 crash if more than 8 test patterns are specified using the -t option.
2616 (Addresses Debian Bug: #487298)
2618 Add support to badblocks to limit how quickly it reads from the disk
2619 drive (so it can be used for background scrubbing), and so it will
2620 abort after finding a given number of errors.
2622 Remove support for the legacy big-endian filesystem format which only
2623 existed on extremely long-dead PowerPC kernels almost a decade ago.
2625 Remove MASIX support from e2fsprogs.
2627 Add I/O statistics reporting to e2fsck.
2629 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
2632 Fixed various Debian packaging issues --- see debian/changelog for
2633 details. (Addresses Debian Bugs: #487443, #487675, #490003)

2654 Clean up the badblocks group so to make it more portable and robust.
2656 Avoid using predictable filenames in /tmp in blkid's regression test
2657 suite. Also remove bashism's in the regression test script.
2659 If the configure script is given --with-diet-libc, don't use thread
2660 local storage, since diet libc doesn't support TLS. (Addresses
2661 Sourceforge Bug: #2000654)
2663 Fix the blkid regression test suite to tolerate older versions of
2664 mkswap that don't support the -U option.
2666 A few library routines have been converted to support 64-bit block
2667 numbers; in particular, the I/O manager functions, the test_io,
2668 inode_io, and unix_io managers have all be converted to support 64-bit
2671 Debugfs can now be extended for use by test programs. See
2672 lib/ext2fs/extents.c for an example for how it can be used. The test
2673 program links against the debugfs object files, and provides
2674 additional commands by defining an auxiliary libss command table.
2676 The lazy_bg filesystem feature, which was only used by developer's
2677 testing, has been removed since it has been largely supplanted by
2678 uninit_bg. This also simplifies the code.
2681 E2fsprogs 1.40.11 (June 17, 2008)
2682 =================================
2684 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
2685 percentage of reserved blocks. (Addresses Debian Bug: #452639)
2687 Updated Spanish and Catalan translations.
2689 Fixed various Debian packaging issues --- see debian/changelog for
2690 details. (Addresses Debian Bugs: #483962, #483023)
2692 Add detection for ZFS volumes to the libblkid library.
2694 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2695 (Addresses Debian Bug: #486463)
2700 Fix marginal C code in probe_lvm2() function to the blkid library more
2701 portable for older compilers.
2703 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
2705 Fix ext2fs_swap{16,32,64} functions so they can be used by external
2706 applications on big-endian machines. (Addresses Debian Bug: #484879)
2709 E2fsprogs 1.40.10 (May 21, 2008)
2710 ================================
2712 When deciding whether or not to revalidate a blkid cache entry, if the
2713 device's mtime is newer than the last time the cached entry was
2714 validated, force a revalidation.
2716 Fix a potential data corruption bug in e2fsck in the journal replay.
2717 The chances of this is happening is extremely remote, especially the
2718 default data=ordered or data=writeback modes. However, if a block
2719 which has been journalled starts with the first four bytes 0xc03b3998,
2720 when e2fsck replays the journal, those four bytes will be replaced
2721 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
2722 metadata to begin with those fatal 4 byte sequence, and unless
2723 data=ordered mode is in use, data blocks are never journaled.
2725 Updated German, Dutch, Sweedish, and Vietnamese translations.
2730 Fixed various Debian packaging issues --- see debian/changelog for
2733 Remove default sizes of types when cross compiling, since autoconf
2734 2.50 can figure this out automatically now.
2737 E2fsprogs 1.40.9 (April 27, 2008)
2738 =================================
2740 SuSE's security team audited uuidd and came up with a few minor
2741 issues. None of them are serious given that uuidd runs setuid as a
2742 unprivileged user which has no special access other than libuuid
2743 directory, but it's good to get them fixed.
2745 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
2746 work correctly with in-inode extended attributes.
2748 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
2751 Debugfs will avoid using a pager if the standard output is not a tty.
2753 Fix debugfs and tune2fs to correctly handle daylight savings time when
2754 parsing a time string.
2756 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2758 Fix fsck completion bars when multiple filesystems were being checked
2759 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
2760 #203323, Addresses Sourceforge Bug: #1926023)
2762 Fix fsck so that progress information is sent back correctly when
2763 multiple filesystems are being check and the output of fsck is being
2764 redirected to a file descriptor. Also, include the device name (w/o
2765 spaces) in the progress information sent back via a file descriptor.
2766 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
2769 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
2771 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
2772 signal to its child process.
2774 Fix mke2fs's creation of are resize inode when there is a non-standard
2775 s_first_data_block setting.
2777 Fix bug in blkid when run by an unprivileged user; most devices were
2778 not reported correctly. 9Addresses Launchpad Bug: #220275)
2780 Mke2fs will not allow the logically incorect combination of
2781 resize_inode and meta_bg, which had previously caused mke2fs to create
2782 a corrupt fileystem.
2784 Fix fsck in German locales so that a 'j' means yes.
2785 (Addresses Sourceforge Bug: #1947683)
2791 Fixed various Debian packaging issues --- see debian/changelog for
2794 Update valgrind options in test_script to work with valgrind 3.2.3
2796 Update texinfo.tex to a much newer version from the FSF.
2798 Remove bashism for configure script and from the lib/ss Makefile.
2799 Addresses Sourceforge Bug: 1921969
2801 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
2803 Fix build system so that if texinfo is not installed, it won't print a
2804 (harmless) error message.
2807 E2fsprogs 1.40.8 (March 13, 2008)
2808 =================================
2810 Fixed e2image -I so it works on image files which are larger than 2GB.
2812 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
2813 the size is larger than the number of blocks found in the inode, don't
2814 try to allocate extra empty blocks at the end of the directory to make
2815 up the difference; there's no point to doing that. In addition, if
2816 the size is not a multiple of a blocksize, always fix it.
2818 E2fsck handled a pass 2 "should never happen error" by not giving
2819 enough information and then core dumping. Unfortunately, it was all
2820 too easy to trigger the "should never happen" situation if a
2821 directory's inode size was not correct. This has been fixed, but
2822 e2fsck has also been taught how to handle this situation more
2823 gracefully, by simply removing the inode hash tree information, so
2824 that it can be rebuilt again after e2fsck's pass 3. (Addresses
2825 Launchpad Bug: #129395)
2827 Resize2fs had a bug resizing large inodes with extended attributes
2828 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2829 completely on big-endian systems such as PowerPC. The bug should be
2830 completely fixed now. Yay for regression test suites. (Addresses Red
2831 Hat Bugzilla: #434893)
2833 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
2834 translations. Many thanks to Philipp Thomas from Novell for stepping
2835 up to become the new German translation maintainer! (Addresses Debian
2836 Bugs: #302512, #370247, #401092, #412882).
2838 When e2fsck is clearing a corrupt inode's HTREE directory information,
2839 make it clear that it is just clearing the HTREE information, not the
2842 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2847 Add new functions, ext2fs_dblist_get_last() and
2848 ext2fs_dblist_drop_last(), which allows the caller to examine the last
2849 directory block entry added to the list, and to drop if it necessary.
2851 Fixed a portability problem in libblkid with DJGPP.
2853 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
2854 to Philipp Thomas for pointing this out.
2856 If the info files are not built, change "make install" so it doesn't
2857 fail with an error code.
2860 E2fsprogs 1.40.7 (February 28, 2008)
2861 ====================================
2863 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2864 depreciate the -s option, since it can result in filesystems which
2865 e2fsck can't fix easily. There are very good reasons for wanting to
2866 disable sparse_super; users who wants to turn off sparse_super can use
2867 debugfs. (Addresses Sourceforge Bug: #1840286)
2869 Add missing options to mke2fs's usage message. (Addresses Sourceforge
2872 Fix bug in resize2fs when large (greater than 128 byte) inodes are
2873 moved when a filesystem is shrunk; it was only moving the first 128
2874 bytes, so extended attributes were not getting moved. (Addresses Red
2875 Hat Bugzilla: #434893)
2877 E2fsck now prints an explicit message when the bad block inode is
2878 updated, to avoid confusion about why the filesystem was modified.
2879 (Addresses Sourceforge Bug: #756460)
2881 Allow mke2fs and tune2fs manipulate the large_file feature.
2882 Previously we just let the kernel and e2fsck do this automatically,
2883 but e2fsck will no longer automatically clear the large_file feature.
2884 It still isn't really necessary to worry about this feature flag
2885 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
2888 Suppress message about an old-style fstab if the fstab file is empty.
2889 (Addresses Debian Bug: #468176)
2891 Fix (really minor) bug in debugfs's find_free_block so it avoids
2892 reporting a free block more than once if there are too few free blocks
2893 in the filesystem. (Addresses Sourceforge Bug: #1096315)
2895 Change e2fsck to no longer clear the LARGE_FILES feature flag
2896 automatically, when there are no more > 2GB files in the filesystem.
2897 It's been almost a decade since there have been kernels that don't
2898 support this flag, and e2fsck clears it quietly without telling the
2899 user why the filesystem has been changed.
2901 Fix bug which could cause libblkid to seg fault if a device mapper
2902 volume disappears while it is being probed. (Addresses RedHat
2905 Inhance e2fsck's reporting of unsupported filesystem feature flags.

2908 Fix option syntax in dumpe2fs for explicit superblock and blocksize
2909 parameters. What was currently documented in the man page has been
2910 broken for some time, due to getopt() implementation changes. The
2911 option sytax has been changed to one which is can be more portable
2912 supported and which is consistent with the format for extended options
2913 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)

2951 partially filled-in filesystem object on an error, so that e2fsck can
2952 print more intelligent error messages.
2954 Add a new function e2p_edit_feature2() which allows the caller to
2955 specify which feature flags are OK to set or clear, and which returns

2962 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
2965 Change configure.in to avoid using the 'dc' command unless it is
2966 absolutely needed. (i.e., when using parsing a WIP-style version
2967 number) (Addresses Sourceforge Bug: #1893024)
2969 Add portability checks to support compilation under DJGPP.
2971 Update to the latest samba tdb code before the LGPLv3 change, which
2972 fixes a realloc() leak on failure.
2974 Fix memory leak in ext2fs_alloc_block().
2976 Fix makefile dependency issues for various install targets.
2977 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
2979 Improve descriptions for the r_move_itable and r_resize_inode tests.
2982 E2fsprogs 1.40.6 (February 9, 2008)
2983 ===================================
2985 Add support for returning labels for UDF filesystems in the blkid
2988 Fix bug in the blkid library where cached filesystems was not being
2989 flushed when opening USB devices returned the error ENOMEDIUM.
2990 (Addresses Debian Bug: #463787)
2992 Added logic to the blkid library to automatically choose whether a
2993 filesystem should be mounted as ext4 or ext4dev, as appropriate.
2995 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
2997 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
2998 configured with --enable-jbd-debug.
3000 Document the BLKID_FILE environment variable in the libblkid man page
3005 Update e2fsprogs translation template and Vietnamese and Czech translations
3007 Fixed various Debian packaging issues --- see debian/changelog for
3008 details. (Addresses Debian Bugs: #436058)
3010 Don't try to create $DESTDIR/etc/init.d as part of make install as we
3011 don't install the init.d script (and it's not the recommended way to
3012 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
3014 Use thread local storage to fix a theoretical race condition if two
3015 threads try to format an unknown error code at the same time in the
3019 E2fsprogs 1.40.5 (January 27, 2008)
3020 ===================================
3022 Fix a potential overflow big in e2image if the device name is too
3025 Mke2fs will now create new filesystems with 256 byte inodes and the
3026 ext_attr feature flag by default. This allows for much better future
3027 compatibity with ext4 and speeds up extended attributes even on ext3
3030 Teach e2fsck to ignore certain "safe" filesystem features which are
3031 set automatically by the kernel. Having the kernel set features
3032 automagically behind the user's back is a bad idea, and we should try
3033 to break the kernel of this habit, especially for the newer ext4
3034 feature flags. But for now, we will try to avoid needless full checks
3035 which can annoy users who are doing fresh installs.
3037 Add support in tune2fs and mke2fs for making a filesystem as being "ok
3038 to be used with test kernel code". This will be needed for using test
3039 filesystems with the latest ext4 kernel code.
3041 Change e2fsck -fD so that it sorts non-htree directories by inode
3042 numbers instead of by name, since that optimizes performances much
3043 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
3045 If e2image fills the disk, fix it so it exits right away instead of
3046 spewing large numbers of error messages.
3047 (Addresses-Sourceforge-Feature-Request: #606508)
3049 If ftruncate64() is not available for resize2fs, let it use ftrucate()
3050 instead, but have it check to see if the size would get truncated, and
3051 skip calling ftruncate in that case.
3053 Add support for detecting HFS+ filesystems in the blkid library.
3055 Add supprt in the blkid library for ext4/ext4dev filesystems.
3057 Fix a bug in blkid where it could die on a floating point exception
3058 when presented with a corrupt reiserfs image.
3060 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
3061 such that UUID string is a fixed length.
3063 Add sample python bindings for the uuid library to the contrib
3064 directory. (Addresses-Sourceforge-Patches: #778817)
3066 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
3067 will work with large files. (Addresses Sourceforge Feature Request:
3068 #1257500 and Sourceforge Support Request: #1253511)
3070 Allow the debugfs 'undel' command to undelete an inode without linking
3071 it to a specific destination directory, since this might require
3072 allocating blocks that could overwrite some yet-to-be-recovered
3073 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
3075 Update Swedish translations from the Translation Project.
3080 Fix configure handling of --sbindir (which should rarely be used, but
3081 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
3084 Updated e2fsprogs.spec file to include a new uuidd package
3086 Use pkg-config to determine where to find the devmapper library so we
3087 can find out where it is located on different distributions.
3089 Fix Makefile race so that "make -j3 distclean" works correctly
3091 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
3092 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
3095 Fixed spelling mistakes, typos, and otherwise clarified man pages.

3098 details. (Addresses Debian Bugs: #459403, #459475, #459614)
3100 Remove the --enable-dynamic-static configure option, and build e2fsck
3101 dynamically by default. If the user wants e2fsck.static, he/she will
3102 need to build it via "make -C e2fsck e2fsck.static"
3104 Fix various build warnings due to missing prototypes.

3108 E2fsprogs 1.40.4 (December 31, 2007)
3109 ====================================
3111 Improve time-based UUID generation. A new daemon uuidd, is started
3112 automatically by libuuid if necessary. This daemon is setuid to allow
3113 updates to /var/lib/libuuid, so the clock sequence number can be
3114 stored and so if the clock is set backwards, it can be detected.
3115 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
3118 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
3119 superblocks. This avoids e2fsck from concluding that a full
3120 filesystem check is required before backing up the superblock due to
3121 changes in the feature flags. (Addresses Debian Bug: #454926)
3123 Fix fsck to only treat the '#' character as a comment at the beginning
3124 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
3125 will cause fsck to issue an bogus warning message.
3126 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
3128 Format control characters and characters with the high eighth bit set
3129 when printing the contents of the blkid cache, to prevent filesystems
3130 with garbage labels from sending escape sequences to the user's screen
3131 that might, for example place it in graphics mode. (Addresses Ubuntu
3134 Fix sign-extension problem on 64-bit systems in in the com_err
3135 library. (Addresses Sourceforge Bug: #1809658)
3137 Avoid division by zero error when probing an invalid FAT filesystem in
3138 the blkid library. (Addresses Sourceforge Bug: #1831627)
3140 Update Dutch, Polish, and Vietnamese translations from the Translation
3141 Project. Remove the Rwandan translation upon advice of the
3142 Translation Project.
3147 Fix the libss "make check" regression test so that it works if the
3148 current directory is not in the user's path or if the libss shared
3149 library is not installed. (Addresses Sourceforge Bug: #1848974)
3151 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3152 (Addresses Debian Bugs: #444883, #441872)

3163 E2fsprogs 1.40.3 (December 5, 2007)
3164 ===================================
3166 Fix a potential security vulnerability where an untrusted filesystem
3167 can be corrupted in such a way that a program using libext2fs will
3168 allocate a buffer which is far too small. This can lead to either a
3169 crash or potentially a heap-based buffer overflow crash. No known
3170 exploits exist, but main concern is where an untrusted user who
3171 possesses privileged access in a guest Xen environment could corrupt a
3172 filesystem which is then accessed by the pygrub program, running as
3173 root in the dom0 host environment, thus allowing the untrusted user to
3174 gain privileged access in the host OS. Thanks to the McAfee AVERT
3175 Research group for reporting this issue. (Addresses CVE-2007-5497.)
3177 Fix hueristics in blkid which could cause a disk without partitions to
3178 be incorrectly skipped when a loopback device is present. (Addresses
3179 Red Hat Bugzilla #400321.)
3181 Fix e2image so that in raw mode it does not create an image file which
3182 is one byte too large.
3184 Change mke2fs's usage message so it recommends the preferred -E option
3185 instead of the deprecated -R option.
3187 Enhance the blkid library so it will recognize squashfs filesystems.
3188 (Addresses Red Hat Bugzilla #305151.)
3190 Enhance e2fsck so it will force the backup superblocks to be backed up
3191 if the filesystem is consistent and key constants have been changed
3192 (i.e., by an on-line resize) or by e2fsck in the course of its
3195 Enhance blkid's detection of FAT filesystems; so that USB disks with
3196 only a single bootable partition will not get missed.
3198 E2fsck will no longer mark a filesystem as invalid if it has time
3199 errors (i.e., if superblock mount time or last write time is in the
3200 future) and the user refuses to fix the problem.
3202 The Ubuntu init scripts don't properly set the system time correctly
3203 from hardware clock if the hardware clock is configured to tick local
3204 time instead of GMT time. Work around this as best as we can by
3205 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
3206 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
3209 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
3210 Hat Bugzilla #151533.)
3212 Fix e2fsck so that if the superblock is corrupt, but still looks
3213 vaguely like an ext2/3/4 superblock, that it automatically tries to
3214 fall back to the backup superblock, instead of failing with a hard
3217 Make the e2fsprogs program more robust so that they will not crash
3218 when opening a corrupt filesystem where s_inode_size is zero.
3220 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
3221 arguments are detected as such and the parse error is reported to the
3222 user. (Addresses Debian Bug #435381.)
3224 Change e2fsck so it will not complain if a file has blocks reallocated
3225 up to the next multiple of a system's page size.
3227 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
3228 about (valid) filesystems where the inode table extends to the last
3229 block of the block group. (Addresses Red Hat Bugzilla #214765.)
3231 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
3232 allocating inode tables for some relatively rare odd disk sizes.
3233 (Addresses Red Hat Bugzilla #241767.)
3235 Add Catalan translation and update Dutch and Swedish translations
3236 from the Translation Project.
3238 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
3239 still had an issue when trying to figure out whether we need to
3240 byte-swap fast symlinks that contained extended attributes.
3242 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3243 (Addresses SourceForge Bug #1821333.)
3249 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
3251 Add "make check" to the RPM spec file
3253 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
3254 works correctly when the prefix is not the root directory.
3256 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
3257 clena up after themselves by deleting the test.img temporary file
3258 after completing the test.
3260 Fixed a corner case bug ext2fs_unlink() when trying to delete the
3261 first directory entry in a directory block and the last directory
3262 entry in the previous directory block is not in use. Fortunately
3263 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
3264 places where it is extremely unlikely to run into this corner case.
3266 Fix missing dependency which would cuase parallel builds to fail.
3267 (Addresses Sourceforge Bug #1842331.)
3269 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
3270 calling open(O_CREATE) with a missing mode parameter.
3272 Fix the test_ss.c in lib/ss so it can be used as an example
3273 application program for the library as well as a regression test
3276 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
3277 are properly passed back up through the call stack.
3279 E2fsprogs 1.40.2 (July 12, 2007)
3280 ================================
3282 A recent change to e2fsck_add_dir_info() to use tdb files to check
3283 filesystems with a very large number of filesystems had a typo which
3284 caused us to resize the wrong data structure. This would cause a
3285 array overrun leading to malloc pointer corruptions and segfaults.
3286 Since we normally can very accurately predict how big the the dirinfo
3287 array needs to be, this bug only got triggered on very badly corrupted
3290 Fix a bug in e2fsck which caused it to incorrectly salvange
3291 directories when the last entry's rec_len is bogusly too big. This
3292 resulted in a nonsense filesystem corruption to be reported, and
3293 required a second run of e2fsck to fully fix up the directory.
3295 Update tune2fs man page to include more discussion of reserved blocks
3296 (Addresses Launchpad bug #47817)
3298 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
3302 E2fsprogs 1.40.1 (July 7, 2007)
3303 ===============================
3305 Fix bug which could cause libblkid to loop forever. When revalidating
3306 a partition where there is obsolete information in /etc/blkid.tab, we
3307 end up freeing a the type tag without clearing dev->bid_type, causing
3308 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
3310 The Turkish translation has a bug in it where it has the translation
3311 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
3312 @E, recursively, forever, until the stack fills up and e2fsck core
3313 dumps. We fix this by making e2fsck stop @-expansions after a
3314 recursive depth of 10, which is far more than we need.
3315 (Addresses Sourceforge Bug: #1646081)
3317 Compile the default mke2fs.conf into mke2fs program. People are
3318 getting surprised by mke2fs creating filesystems with different
3319 defaults than earlier versions of mke2fs if mke2fs.conf is not
3320 present. So we now create a built in version of mke2fs.conf file
3321 which is used by mke2fs if the /etc/mke2fs.conf is not present.
3322 (Addresses SourceforgeBug: #1745818)
3324 Improve the config/parse_types.sh helper script. Fix a potential
3325 security problem if e2fsprogs is built as root (as Gentoo does!). In
3326 addition fix the script and how it is called from the configure script
3327 so that it does the right thing when cross-compiling. (Fixes Gentoo
3330 Update Vietnamese, French, and Dutch PO files from the Translation
3331 Project. Also created a new e2fsprogs.pot file for translator.
3333 Fix bogus strip permission errors when building under Debian. When
3334 building the e2fsprogs dpkg's, the dh_strip command emits a large
3335 number of error messages caused by the permissions not being right.
3336 So run dh_fixperms before running dh_strip.
3341 Add new function: profile_set_default(). This function sets the value
3342 of the pseudo file "<default>". If the file "<default>" had
3343 previously been passed to profile_init(), then def_string parameter
3344 will be parsed and used as the profile information for the "<default>"
3347 Fix mk_cmds's error reporting so that it is unambiguous that it is the
3348 mk_cmds script which is generating the error. (Obviates Gentoo patch:
3349 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
3351 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
3352 priority" environment variable that overrides all others, where as
3353 LANG is the lowest priorty environment variable. If LC_ALL is set, it
3354 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3355 the all the rest are set. This will assure that the locale when
3356 running the test suites is the "C" locale. (Obviates Gentoo patch:
3357 e2fsprogs-1.38-tests-locale.patch)
3360 E2fsprogs 1.40 (June 29, 2007)
3361 ==============================
3363 Fix divide by zero error in blkid's NTFS probing logic.
3365 Add new blkid -g option which causes the blkid cache to be garbage
3368 Fix a bug in libblkid which could cause the internal field bid_type to
3369 become corrupted. Fortunately bid_type isn't used much, and bid_label
3370 and bid_uuid is only used by debugging code, so the impact of this bug
3373 Mke2fs will now store the RAID stride value when a filesystem is
3374 created with a requested RAID stride, and then use it automatically in
3377 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3378 isn't too big. In some cases Lustre users have tried specifying an
3379 inode size of 4096 bytes, while keeping an inode ratio of one inode
3382 Improve sanity check in e2fsck's algorithm for finding a backup
3383 superblock, so that it won't accidentally find a superblock that was
3384 located in the journal, and then later reject it as being not a valid
3387 Fix e2fsck get_size logic so that it will work with the Linux floppy
3388 driver. The Linux floppy driver is a bit different from the other
3389 block device drivers, in that if the device has been opened with
3390 O_EXCL, it disallows another open(), even if the second open() does
3391 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
3393 Fix error checking of badblock's last-block and start-block arguments.
3394 (Addresses Debian Bug: #416477)
3396 Fix e2fsck so that it doesn't overwrite the backup superblocks when
3397 recovering a journal until the master superblock has been confirmed as
3400 Change the blkid library to be much more paranoid about concluding
3401 that a partition contains an NTFS filesystem, and fetch the UUID and
3402 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
3405 Factor out the code which sets the default journal size and move it
3408 Enhance e2fsck so it will recreate the ext3 journal if the original
3409 journal inode was cleared to due it being corrupt after finishing the
3412 Fix e2fsck so that it updates the journal inode if it is corrupted and
3413 the backup journal information from the superblock was successfully
3414 used to recover the filesystem.
3416 Fix e2fsck so that it checks all of the blocks in the journal inode
3417 for validity. The original code only checked the direct blocks to
3418 make sure the journal inode was sane. Unfortunately, if some or all
3419 of the indirect or doubly indirect blocks were corrupted, this would
3422 Add support in blkid to detect LUKS encrypted partitions.
3424 Add extra sanity checks for extended attributes in the case where the
3425 size is zero but the offset is very large.
3427 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3428 and ext2fs_get_next_inode_full().
3430 Clarify the copyright licenses used by the various libraries in
3431 the top-level COPYING file (Red Hat Bugzilla: 166058)
3433 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3435 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3437 Remove check in e2fsck which requires EA's in inodes to be sorted;
3438 they don't need to be sorted, and e2fsck was previously wrongly
3439 clearing unsorted EA's stored in the inode structure.
3441 Allow mke2fs or tune2fs to create a substantially larger journal (up
3442 to 10,240,000 blocks).
3444 Fix MD superblock detection, and make sure the correct UUID is
3445 reported from the MD superblock.
3447 Fix a signed vs. unsigned bug in debugfs.
3449 Enhance debugfs's date parser so that it accepts integer values.
3451 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3452 file with multiply claimed blocks is hard linked. or not at all if the
3453 root directory contains shared blocks
3455 Enhance debugfs so it can modify the block group descriptors using the
3456 command set_block_group_descriptor.
3458 Improve e2fsck's reporting of I/O errors so it's clearer what it was
3459 trying to do when an error happens
3461 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3462 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:

3479 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3480 field on the first pass.
3482 Fix e2fsck to set the file type of the '..' entry when connecting
3483 a directory to lost+found. (Addresses Lustre Bug: #11645)
3485 Enhance e2fsck to recover directories whose modes field were corrupted
3486 to look like special files. This is probably only useful in
3487 artificial test cases, but it will be useful if we ever do the "inodes
3488 in directory" idea for ext4.
3490 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
3493 Fix resize2fs parsing of size parameter (in sector units). This was
3494 actually a bug in libe2p's parse_num_blocks() function. When handling
3495 the 's' suffix, it was ignoring the blocksize information passed in
3496 from the caller and always interpreting the number in terms of a 1k
3497 blocksize. (Addresses Debian Bug: #408298)
3499 There was a floating point precision error which could cause e2fsck to
3500 loop forever on really big filesystems with a large inode count.

3503 Fix memory leak in ext2fs_write_new_inode()
3505 Add support for using a scratch files directory to reduce e2fsck's
3506 memory utilization on really big filesystems. This uses the TDB
3507 library. See the [scratch_files] section of the e2fsck.conf man page
3510 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
3511 platform (Addresses Debian Bug: #397044)

3516 Allow debugfs and dumpe2fs to support fs features under development.
3518 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3519 ext2fs_open() , which allows application to open filesystes with features
3520 which are currently only partially supported by e2fsprogs.
3522 Allow unix_io to support offsets greater than 2G (Addresses
3523 SourceForge Bug: #1547922)
3525 Fixed overflow and signed/unsigned problems caused by the number of
3526 blocks or inodes exceeding 2**31 or being close to 2**32-1.
3528 Add support for unsigned directory hash calculations with hints in the
3529 superblock to fix cross-architectural portability for htree
3530 directories with filenames where the high 8th bit is set. (Addresses
3533 Fix resize2fs so that it gives user-intelligible error messages if the
3534 filesystem or the kernel does not support on-line resizing.

3537 Require mke2fs -F -F for really dangerous operations, since -F is
3538 needed for less dangerous operations such as creating filesystems
3539 images in regular files, or creating filesystems on whole block
3540 devices. These relatively innocuous usages should NOT be confused
3541 with running mke2fs on an apparently-mounted or in-use filesystem.
3543 Allow the default inode size to be specified into the mke2fs.conf
3546 Make the smallest default journal size is big enough so that on-line
3547 resizing should always work.
3549 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
3552 Fix debugfs coredump when lsdel is run without an open filesystem
3553 (Addresses Debian Bug: #378335)
3555 Fix debugfs display bug us that bytes that have the high bit set are
3556 displayed as "ec" instead of "ffffffec".
3558 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3560 Device mapper scanning wasn't working in the blkid library because the
3561 pathnames had an extra "/dev" when they were being probed.
3563 Add GFS/GFS2 support to the blkid library.
3565 Fix blkid support of empty FAT filesystem labels.
3567 Avoid recursing forever (or for a long time) when the blkid library
3568 searches for a device and there are symlinks to directories in /dev.
3570 Avoid unaligned halfword access in blkid when accessing FAT
3571 superblocks, as this will cause Sparc/Solaris systems to throw a

3578 Improve the (non-installed, for experts only) findsuper program by
3579 printing the uuid and label from the superblocks, as well as the
3580 starting and ending offsets of the filesystem given the information in
3581 the superblock. Omit by default printing superblocks that are likely
3582 found in located in an ext3 journal unless an explicit -j option is
3585 Updated Spanish, French and Dutch translations and added Catalan
3586 translation. (Addresses Debian bug: #411562)
3588 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3589 determining a partition's size, since binary searching to determine
3590 the device doesn't work on FreeBSD.
3592 Documentation about UUID's is available in enough places, and it's
3593 awkward to deal with debian-legal's insanities. So I'm caving in the
3594 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3595 don't have do the dfsg tarball. Also remove the rule that only tried
3596 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3597 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
3599 Fix the info-dir line so that the menu name does not contain a .info
3600 prefix. First of all, it's ugly, secondly, it causes the install-info
3601 command to fail to remove the com_err info file from the
3602 /usr/share/info/dir file when the comerr-dev package is removed and
3603 purged. (Addresses Debian Bug: #401711)

3616 E2fsck now supports the %It expansion when printing a problem report.
3617 It will print the type of the inode in the problem context.
3619 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
3620 (Addresses Sourceforge Bug: #1565561)
3622 Remove unused variables and other lint/gcc -Wall cleanups
3624 Add check to ext2fs_get_device_size() so it will return EFBIG for for
3625 filesystems contained in regular files where the filesystem image size
3626 is returned by stat64().
3628 Set local environment variables to C so mk_cmds and compile_et always
3629 work. (Addresses SourceForge Bug: #1532177)
3631 Added the 64-bit byte swapping function ext2fs_swab64().
3633 Added two new helper functions to prevent 2**31/2**32-1 overflow
3634 problems: ext2fs_div_ceil() and e2p_percent().
3636 Create new ext2fs library inline functions ext2fs_group_first_block()
3637 and ext2fs_group_last_block() in order to calculate the starting and
3638 ending blocks in a block group.
3640 Create the generated files read-only to remind developers not to edit them.
3642 Add support for autoconf 2.60 (with backwards compatibility for older
3643 versions of autoconf).
3645 Added an "make rpm" target to top-level Makefile
3647 Added various FreeBSD portability fixes.
3649 Exclude mercurial files from the RPM build tree to speed up copy/build.
3651 Use root_sysconfdir to define the locations of mke2fs.conf and
3652 e2fsck.conf instead of using a hard-coded /etc pathname.
3654 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3656 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3658 If diff -u is supported, use it to report test failures.
3660 Updates/improvements to RPM spec file
3662 Add on-disk format definitions for the following new features:
3663 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3664 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3665 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3667 Add a new make target "checked-failed" in the tests directory which
3668 reruns any failed tests
3670 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3672 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3673 pointer dereferences, memory leaks, etc. None were security-criticial
3676 Fix up usage and decrement error messages in the test_icount program
3678 Add debugging code to the com_err library; if the environment variable
3679 COMERR_DEBUG is set to 1, print out debugging messages as error tables
3680 are added and removed from the com_err library. If the
3681 COMERR_DEBUG_FILE environment variable is set (and the process is not
3682 setuid) the debugging messages may be redirected to a file.
3684 Change all of the e2fsprogs programs to use the newer add_error_table()
3685 and remove_error_table() interfaces instead of the much older
3686 initialize_*_error_table() function.
3688 Add TDB support into the ext2fs library. This allows us to have a
3689 guaranteed library we can count on always being present so we can
3690 store data in an on-disk database.
3692 Add support for using TDB to store the icount data, so we don't run out
3693 of memory when checking really large filesystems.
3695 Change the regression test suite so that it skips empty test directories.
3697 Define the l_i_iversion field in ext2_inode. The l_i_version field is
3698 now defined from the old l_i_reserved1 field in the ext2 inode. This
3699 field will be used to store high 32 bits of the 64-bit inode version
3702 Add Makefile production rule for e2fsprogs.spec in case it gets
3705 Add new function profile_get_uint() to allow for a clean way to fetch
3706 unsigned integers from the context.
3708 Add test to make sure the ext2 superblock structure is 1024 bytes.
3710 Fix typo in name of f_dup4 regression test
3712 Add new function blkid_gc_cache() which performs a garbage collection
3713 pass on the /etc/blkid.tab file.
3715 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
3716 general, only e2fsck (after the filesystem is clean), tune2fs, and
3717 resize2fs should change the backup superblocks by default. Most
3718 callers of ext2fs_open() should not be touching any superblock fields
3719 which require the backups to be touched.
3721 Add new function to libext2fs, ext2fs_default_journal_size(), which
3722 returns the default journal size.
3725 E2fsprogs 1.39 (May 29, 2006)
3726 =============================
3728 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3729 between 2**31 and 2**32 blocks.
3731 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3732 configure the filesystem features, blocksize, and inode_ratio for
3733 different filesystem types.
3735 Mke2fs will now create filesystems hash trees and on-line resizing
3736 enabled by default, based on the new /etc/mke2fs.conf file.
3738 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3739 filesystem device node in exclusive mode to prevent accidents by
3740 system administrators. In the case of resize2fs and mke2fs, it will
3741 only use exclusive mode if the filesystem is not mounted.
3743 Fixed a bug in mke2fs which caused it to to fail when creating the
3744 resize inode for large filesystems. (Addresses Debian Bug #346580)
3746 When allocating space for the RAID filesystems with the stride
3747 parameter, mke2fs will now place each portion of the group's inode
3748 table right up after the superblock (if present) in order to minimize
3749 fragmentation of the freespace.
3751 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3752 efficiently by writing the inode and block bitmaps in one pass, thus
3753 reducing the number of disk seeks required.
3755 Add support for on-line resizing to resize2fs.
3757 Fix blkid library so that logic to determine whether or not a device's
3758 cached information in /etc/blkid.tab needs to be verified or not
3759 doesn't get confused by a system clock which is insane (for example,
3760 if the battery is dead on a Macintosh running PPC Linux. (Addresses
3761 Red Hat Bug: #182188)
3763 The blkid library will now store the UUID of the external journal used
3764 by ext3 filesystems, so that in the future, the userspace mount binary
3765 can use this to find the location of the external journal and pass
3766 this information to the kernel.
3768 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3769 control how various options should be handled. See the e2fsck.conf
3770 man page for more details. (Addresses Debian Bug: #150295)
3772 E2fsck now prints an explanatory message when delaying a filesystem
3773 check when the system is running on battery. (Addresses Debian Bug:
3776 E2fsck will detect if the superblock's last mount field or last write
3777 field is in the future, and offer to fix if so. (Addresses Debian Bug
3778 #327580) These problems will be fixed automatically in preen mode
3779 since Debian's boot sequence bogusly doesn't set the time correctly
3780 until potentially very late in the bootup process, and this can cause
3781 false positives which will cause users' systems to fail to boot.
3782 (Addresses Debian Bugs #343662 and #343645)
3784 E2fsck now checks to see if the superblock hint for the location of
3785 the external journal is incorrect, and if so, offer to update it.
3786 (Addresses Debian Bug: #355644)
3788 Fix e2fsck from segfaulting on disconnected inodes that contain one or
3789 more extended attributes. (Addresses Debian Bug: #316736, #318463)
3791 E2fsck will stop and print a warning if the user tries running a
3792 read/write badblocks test on a read-only mounted root filesystem.
3794 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
3795 C. Thompson for pointing these out; they were originally found using
3798 When resizing a file containing a filesystem, resize2fs will expand or
3799 truncate a file as necessary. (Addresses Debian Bug: #271607)
3801 Resize2fs will now automatically determine the RAID stride parameter that
3802 had been used to create the filesystem, and use that for newly created
3803 block groups. The RAID stride parameter may also be manually specified
3804 on the command line using the new -S option to resize2fs.
3806 Fix mke2fs so that it correctly creates external journals on
3807 big-endian machines (such as a S/390).
3809 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3810 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
3811 Chambraud for pointing this out.)
3813 Dumpe2fs will now print the size of the journal (if present).
3815 Fix debugfs's set_inode_field command so it can properly set the frag,
3816 fsize, uid_high, gid_high, and author fields in the inode instead of
3817 silently failing, and so that setting the i_size actually sets i_size
3820 Add a new debugfs command, set_current_time, which sets fs->now so
3821 that regression test suites can repeatedly modify the filesystem's
3824 Fix a bug in debugfs's icheck which would incorrectly report the owner
3825 of an extended attribute block.
3827 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3828 print a usage message when an illegal option character is given.
3830 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3831 so it won't core dump. (Addresses SourceForge bug #1424311)
3833 Fix mklost+found so that it creates a full-sized directory on
3834 filesystems with larger block sizes.
3836 Fix a file descriptor leak in blkid library.
3838 Fix a display bug in "badblocks -sv" so that the done message properly
3839 clears the block number at the end of the test. (Addresses Debian Bug
3842 Allow fractional percentages to the -m option in mke2fs and tune2fs

3845 Use fstat/fstat64 in getsize.c if the the target is a regular file,
3846 instead of attempting to do a binary search. Fix some fd leaks in
3849 Add support for device mapper library to the blkid library to ensure
3850 that the "best" (i.e., leaf) device is probed by the blkid library.
3852 Fix the blkid library so that it notices when an ext2 filesystem is
3855 Improve the blkid's library VFAT/FAT detection; it now understands
3856 labels stored in the root directory, and is more paranoid about
3857 checking the FAT superblock values.
3859 Fixed a fd leak in the uuid library which was causing problems for the
3860 LVM tools. (Addresses Debian Bug: #345832)
3862 Add support for the reiser4 and software suspend partitions to the
3863 blkid library. Also add support for extract the label from iso9660
3866 Fix a compile_et bug which miscount the number of error messages if
3867 continuations are used in the .et file.
3869 Add extra sanity checks to protect users from unusual cirucmstances
3870 where /etc/mtab may not be sane, by checking to see if the device is
3871 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
3874 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
3875 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
3877 Fix use-after-free bug in e2fsck when finishing up the use of the
3878 e2fsck context structure.

3897 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
3898 Bugs: #360661, #360317)
3900 Fixed the Makefile so that they work correctly on newer versions of
3901 GNU make (i.e., 3.81).
3903 Add valgrind support to the regression test suites, and eliminate
3904 false positives from valgrind.
3906 Add a regression test suite for the blkid library.
3908 Fix a fencepost error in resize2fs caught by valgrind.
3910 Fix compiler warnings about missing memcpy prototypes.
3912 We no longer have the sparc assembly code in the header file any more,
3913 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
3914 break compiles on the sparc architectures when using gcc.
3916 In the libext2fs library, add the new field fs->now which if non-zero
3917 is used instead of the system time when setting various filesystem
3918 fields (last modified time, last write time, etc.)
3920 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3921 ext2fs.h which is needed since the inline functions use memcpy().
3922 (Addresses Sourceforge Bug #1251062)
3924 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3925 the build system when building files in the util directory which are
3926 needed during the build process. This avoids potential problems when
3927 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3928 are not recognized as valid by the host compiler. (Addresses
3929 Sourceforge Bug #1261547)
3931 Clean up the blkid library by making the superblock and generic i/o
3932 functions to be more generic. Clean up interface to the probe
3933 function, and fix memory leak. Finallly, remove an unneeded reference
3934 to probe.h in the lib/blkid/resolve.c
3936 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3937 of invalid block #'s.
3939 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3940 indicate that the the function read/writes the memory location.
3942 Fix various gcc -Wall complaints.
3944 Add a dependency to make sure that the subdirectories are created
3945 before creating all of the object files, in order to address parallel
3946 build problem in the library Makefiles. (Addresses Sourceforge Bug:
3949 Add $(LDFLAGS) to the command line argument when generating an ELF or
3950 Solaris shared library, to allow cross-compile and other builds that
3951 might need to specify -L paths to needed libraries. (Addresses
3952 Sourceforge Bug #1261549)
3954 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3955 intended for testing purposes. It allows an ext2/ext3 developer to
3956 create very large filesystems using sparse files where most of the
3957 block groups are not initialized and so do not require much disk
3958 space. Eventually it could be used as a way of speeding up mke2fs and
3959 e2fsck for large filesystem, but that would be best done by adding an
3960 RO_COMPAT extension to the filesystem to allow the inode table to be
3961 lazily initialized on a per-block basis, instead of being entirely
3962 initialized or entirely unused on a per-blockgroup basis.
3964 Fix backwards compatibility so e2fsprogs will better compile on Linux
3967 Make test scripts more robust against locale-related environment variables
3969 Fix type warning problem with sizeof() in ext2fs_open2().
3971 Fix type warning problem with time_t in debugfs.
3974 E2fsprogs 1.38 (June 30, 2005)
3975 ==============================
3977 Fix blkid's test programs (built with "make check") compile correctly
3978 even without "configure --enable-blkid-debug".
3980 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3981 type aliasing rules on newer gcc compilers. (Addresses Red Hat
3984 Fix com_err library to make it more compatible with recent changes
3985 made to the com_err library in MIT Kerberos V5 version 1.4.
3986 (Addresses Sourcefroge Bug #1150146)
3988 General cleanup of messages printed by e2fsprogs programs for grammar,
3989 consistency, and to make life easier for translators. Fixed a few
3990 strings containing English that had not been marked as needing
3991 translations. Removed strings that do not need to be translated, to
3992 make life easier for translators.
3994 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3995 test to see if a device appears to be in use instead of just relying
3996 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
3998 Fix portability problem in the filefrag program affecting platforms
3999 where the size of an integer is smaller than the size of a long.
4000 (Addresses Debian Bug #309655)
4002 Mke2fs will now use a larger journal by default for filesystems
4003 greater than 4GB. (128 MB instead of 32MB).
4005 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
4006 unless forced. This is to avoid signed vs. unsigned kernel bugs in
4007 block numbers that still need to be fixed.
4009 The blkid program has a new option which will more efficiently search
4010 for device when it is known (or expected) that only one matching
4011 device will be found in the system, such as when doing a lookup by
4014 Debian's e2fsprogs-specific initrd fragment will avoid including
4015 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
4016 and LD_LIBRARY_PATH, and filtering out libraries found in
4017 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
4019 Fixed a potential portability issue in the blkid programs for
4020 architectures where the char type is unsigned. (Addresses Sourceforge
4023 Fix a bug in filefrag so that it doesn't falsely count an extra
4024 discontinuity when the first block found is an indirect block.
4025 (Addresses Debian Bug #307607).
4027 Fix blkid's recognition of cramfs filesystems, and enhance it to be
4028 able to handle cramfs labels.
4030 Fix debugfs's stat command to not core dump when a filesystem is not
4033 Fix e2fsck's handling of error conditions caused by the resize inode
4034 claiming blocks that are also used by other inodes, a filesystem
4035 corruption which was commonly caused by a bug in Fedora Core 3's
4038 Fixed bug in filefrag which caused it to fail on non-ext2/3
4039 filesystems. (Addresses Debian Bug: #303509)
4041 If the superblock last mount time indicates that the system clock may
4042 not be accurate, then e2fsck will omit checking inodes' deletion time
4043 field for indications of a potential corrupted orphaned inode list.
4044 (Previously e2fsck only ommited these LOW_DTIME checks when the
4045 superblock's last write time looked insane.)
4047 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
4048 (Addresses Debian bug #302200)
4050 Make the blkid library more paranoid about being run from setgid
4051 programs, and to use __secure_getenv() from libc if it is available.

4057 Updated and fixed translations.
4059 Fixed various Debian packaging issues --- see debian/changelog for
4065 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
4066 changed to take an unsigned int for the bit number. Negative bit
4067 numbers were never allowed (and didn't make any sense), so this should
4068 be a safe change. This is needed to allow safe use of block numbers
4069 greater than or equal to 2**31.
4071 The compile_et program will avoid recreating generated foo_err.c and
4072 foo_err.h files if no changes are necessary. The compile_et program
4073 will also atomically replace these files to avoid a potential parallel
4074 build race problem on SMP systems. (Addresses Sourceforge Bug:
4077 Added a new function to the blkid library, blkid_probe_all_new(),
4078 which only probes newly added disk devices, and change
4079 blkid_find_dev_with_tag() to use this function so that when a
4080 requested tag is not found, devices that were previously not checked
4081 are searched before searching all devices in the system.
4083 Added new functions to the blkid library, blkid_dev_set_search() and
4084 blkid_dev_has_tag().
4086 E2fsck's problem strings can now use @m and @n as abbrevations for
4087 "multiply-claimed" and "invalid", respectively.
4089 The e2fsprog.pot file now has an explanation of how the @-expansion
4090 and %-expansion works, and strings in e2fsck/problem.c which contain @
4091 characters now have comments in e2fsprogs.pot with the @-expansion to
4092 make life easier for translators.
4094 Fixed missing return values in the ext2fs library which could cause it
4095 to return random garbage in certain error conditions.
4097 Allow the current time to be overriden via the E2FSCK_TIME environment
4098 variable for use in regression tests.
4100 The test scrpit driver program now exits with a non-zero status if
4101 there any of its test that it ran failed.
4103 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
4106 Fixed "make check" so that it compiles correctly even when e2fsprogs'
4107 header files have not be installed in the system include directories.
4108 (Addresses Sourceforge Bug: #1180572)
4110 Fixed gcc -Wall nits.
4113 E2fsprogs 1.37 (March 21, 2005)
4114 ===============================
4116 Add support for checking the validity of Extended Attributes stored in
4119 Add support for dumping the contents of large inodes to debugfs,
4120 including the extended attributes stored in inodes.
4122 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
4123 when we create a new inode we make sure that the extra information in
4124 the inode (any extra fields in a large inode and any ea-in-inode
4125 information) is initialized correctly. This can take place when
4126 mke2fs creates the root and lost+found directory, when e2fsck creates
4127 a new root inode or a new lost+found directory, and when the user uses
4128 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
4129 create inode could inherit garbage (or old EA information) from a
4130 previously deleted inode.
4132 Fixed a bug in e2fsck so it would notice if a file with an extended
4133 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
4136 Added support to filefrag to detect files which are using the new
4137 experimental file extents format, and use the non-ext2 algorithm in
4138 that case. Fixed a bug to avoid reporting a false discontinuity if
4139 there is one or more unallocated blocks at the beginning of a file.
4141 Duplicated a check for noticing whether or not the number of blocks
4142 (given a certain blocksize) is greater than 2**32 when the
4143 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
4144 allows mke2fs to automatically use a larger blocksize when creating a
4145 filesystem on a very large device when run on systems that do not
4146 support BLKGETSIZE64.
4148 Fix the I18N build which was broken in e2fsprogs 1.36 because the
4149 build system had been switched to treat the .gmo files as shipped
4150 files (for backwards compatibility with systems that have older GNU
4151 I18N tools installed), but the gen_tarball.in script was still
4152 removing the .gmo files from the official source distribution.
4154 Fixed various Debian packaging issues --- see debian/changelog for
4155 details. (Addresses Debian Bugs ##296769, #299341)
4160 Added new functions to the e2p library which convert between a string
4161 and os_type: e2p_os2string() and e2p_string2os(), and used them to
4162 make the generated binaries more compact.
4164 Fixed a compile-time error on Darwin systems.
4166 Cleaned up the lib/ext2fs Makefile slightly.
4169 E2fsprogs 1.36 (February 4, 2005)
4170 =================================
4172 All of the patches that were applied to Fedore Core 3's
4173 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
4174 lot of bug fixes first. Users of Fedora Core 3 are strongly
4175 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
4177 Add support for filesystem with the online resizing via resize inode
4178 feature. Fixed numerous bugs from the Fedora patches. The Fedora
4179 patches also didn't bother to do any consistency checking on the
4180 resize inode, or add any tests to the regression test suite. The "-R
4181 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
4182 being listed in mke2fs's usage message. All of these shortcomings
4183 have been corrected.
4185 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
4186 program. In order to do this, the user must run the commands:
4188 debugfs -w /dev/hdXXX -R "features ^resize_inode"
4189 e2fsck -f /dev/hdXXX
4191 Optionally, the ext2prepare command can be used to re-enable online
4192 resizing after the filesystem has been fixed.
4194 The fsck program will now accept an optional filedescriptor argument
4195 to the -C option. (The Fedora version of this patch would sometimes
4196 cause fsck to ignore a parameter on fsck's command line in some rare
4199 Make sure e2fsprogs doesn't write garbage into the reserved portion of
4202 Make sure resize2fs releases the blocks belonging to the old inode
4203 table blocks when moving the inode table. (Addresses Debian Bug:
4206 Skip the r_resize_inode test if resize2fs is not compiled (due to
4207 configure --disable-resizer)
4209 E2fsck now checks the summary filesystem accounting information, and
4210 if any of the information is obviously wrong, it will force a full
4211 filesystem check. (Addresses Debian Bug #291571)
4213 Fix e2fsck to not complain when the resize_inode feature is enabled,
4214 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
4217 Fix e2fsck to note delete symlinks that contain an extended attribute
4218 after the ext_attr feature flag has been cleared. (Addresses Red Hat
4221 Add new utility program, copy_sparse.c, which is very useful
4222 for dealing with large sparse files (such as e2image files).
4224 Add support for jnl_blocks[] for debugfs's set_super_value.
4226 Fix filefrag so that it works correctly with sparse files.
4228 Filefrag -v will print first and last blocks.
4230 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
4233 Add mke2fs support so that it can support filesystems larger than 4TB
4234 automatically, by retrying with a 4k blocksize if the device size is
4235 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
4238 Change blkid to test for NTFS first because Windows sometimes doesn't
4239 clear enough of the parition to confuse the probing routines into
4240 thinking the old filesystem type is still valid. (Addresses Debian
4243 Add support for swap partition label and uuid's in the blkid library.
4245 Add support to the blkid library to recognize Oracle ASM volumes.
4247 Make blkid -t display all devices that match the specified criteria,
4248 not just the first one, and work more consistently when the blkid
4249 cache file is not available or set to /dev/null. (Addresses Debian
4250 Bug #290530 and #292425)
4252 Badblocks will now correctly display block numbers greater than
4253 999,999,999 in its progress display.
4255 The tune2fs program will not allow the user from setting a ridiculous
4256 number of reserved blocks which would cause e2fsck to assume the
4257 superblock was corrupt. E2fsck's standards for what is a ridiculous
4258 number of reserved block has also been relaxed to 50% of the blocks in
4261 The blkid library will return vfat in preference to msdos, and ext3 in
4262 preference to ext2 (if the journalling flag is set) so that mount will
4263 do the right thing. (Addresses Debian bug #287455)
4265 Mke2fs will now use the -E option for extended options; the old -R
4266 (raid options) option is still accepted for backwards compatibility.
4267 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
4269 Mke2fs will now accept a size in megabytes, gigabytes, and other units
4270 (via "32m" or "4g" on the command line) if the user finds this more
4271 convenient than specifying a block count.
4273 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
4274 cache conherency problem.
4276 Debugfs now supports a new command, set_inode_field, which allows a
4277 user to manually set a specific inode field more conveniently, as well
4278 as set entries in the indirect block map.
4280 Debugfs's set_super_value command has been enhanced so that the user
4281 can set most superblock fields, including the date/time fields and
4282 some of the more newsly added superblock fields.
4284 E2fsprogs programs now accept an offset to be passed to the file
4285 specifiers, via the syntax: "/tmp/test.img?offset=1024".
4287 E2fsprogs programs will now accept blocksizes up to 65536; kernel
4288 support on the x86 doesn't exist for now, but it can be useful on
4289 other architectures with page sizes greater than 4k. There are 2.6
4290 kernel patches out there which enable this, but they are of this
4291 writing still experimental.
4293 The e2image command now takes the -s option which will scramble
4294 directory entries for raw image files.
4296 Fix a file descriptor leak in the filefrag program.
4298 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
4301 Fix bug in debugfs where kill_file would lead to errors when deleting
4302 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
4304 Fix bug in the blkid library when detecting the ocfs1 filesystem
4306 Remove obsolete EVMS 1.x and a.out DLL support.
4308 E2fsck will attempt to recover from a journal containing illegal blocks.
4310 Fixed two potential ordering constraint problems in e2fsck which might
4311 cause the filesystem to be corrupted if e2fsck is interrupted during a
4312 (extremely narrow) race window. Thanks to Junfeng Yang from the
4313 Stanford Metacompilation group for pointing this out.
4315 Fixed bug in e2fsck where it would not accurately detect whether or
4316 not the system is running on adaptor if the ACPI device representing
4317 the AC adapter didn't correspond to the what was used on IBM
4320 Change e2fsck to accept directories greater than 32MB.
4322 Fix e2fsck so that a checkinterval of zero disables a time-based check
4325 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4326 to the PAGER environment variable. (Addresses Debian Bug #239547)
4328 Tune2fs will not mark rewrite the superblock if the feature bitmasks
4331 The debugfs program will set the filetype information when creating a
4334 Add debugfs -d option to use a separate source of data blocks when
4335 reading from an e2image file.
4337 Add e2image -I option which allows the e2image metadata to be
4338 installed into a filesystem.
4340 Fixed bug in the badblocks program which caused "done" to always
4341 appear in english even when a translation was available. (Addresses
4344 The blkid program has a new option -o which controls the output format
4345 of the blkid program; this is makes blkid more convenient to use in
4348 Fix a minor bug in uuid library, which was not using the full 14 bits
4349 of clock sequence when generating UUID's.
4351 Fix a Y8.8888K problem in the uuid library.
4353 Logsave now creates a new session id for itself to avoid getting
4354 killed by init whan transitioning between init levels.
4356 Change the licensing of the UUID library to be the 3-clause BSD-style
4357 license; this allows Apple to use the uuid library in Darwin.
4359 Add ocfs and ocfs2 probe support into the blkid library.
4361 Fix a memory and file descriptor leak in the blkid library.
4363 The blkid library will revalidate the device if the system time is
4364 earlier than last verification time of the device, since that
4365 indicates that the system time is probably nottrustworthy.
4367 The blkid library will override the default location of the blkid.tab
4368 file by the BLKID_FILE environment variable, if it is available.
4370 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4372 Add various portability fixes for lame new versions of glibc, Darwin
4373 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
4374 Bugs #239934, #264630, #269044, #255589, #289133)
4376 Add support for Windows 9x/NT under Cygwin.
4378 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
4379 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
4381 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
4383 Update the rpm spec files so that it works better with Fedora core 2
4386 Fixed various Debian packaging issues (see debian/changelog). In
4387 particular, fixed the Debian initrd scripts. (#241183, #248050,
4394 Fixed various gcc -Wall warnings.
4396 The uuid library now has new functions uuid_unparse_upper() and
4397 uuid_unparse_lower() which forces the case of the hex digits to be
4398 upper case, or lower case.
4400 The build process has been speeded up by enhancing the subst program
4401 to update the modtime on the generated files even when the generated
4402 file hasn't changed.
4404 The uuid library now uses C99 stdint.h types instead of custom types.
4406 Updated config.guess and config.sub with newer versions from the FSF.
4408 Removed out of date .cvsignore files from the source distribution.
4410 The ext2fs_unlink() function will return an error if both the name and
4411 inode number are unspecified, to avoid doing something surprising
4412 (such as unconditionally deleting the first directory entry).
4413 Directory entries are now deleted by coalescing them with the previous
4414 directory entry if possible, to avoid directory fragmentation. This
4415 is not an issue with the e2fsprogs suite, but may be a problem for
4416 some of the users of libext2fs, such as e2tools.
4418 Add support for version numbers of the form "1.36-rc1".
4420 Fix build of mke2fs.static.
4422 Add basic ext2fs library support for large (EA in inode) inodes.
4424 The test_io mechanism can now abort after n reads or writes to a
4425 particular block. The block is specified by TEST_IO_BLOCK environment
4426 variable, and the read/write count by the TEST_IO_READ_ABORT and
4427 TEST_IO_WRITE_ABORT environment variables. The block data is now only
4428 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4430 UUID_DEFINE() in the uuid library now creates a static variable, with
4431 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4432 be used in header files.
4434 Add support for the install-strip and install-shlibs-strip targets, as
4435 suggested by the GNU coding guielines. "make install" no longer
4436 strips the binaries which are installed.
4438 Remove support for the --enable-old-bitops configure option which was
4439 only for very old sparc systems.
4441 Remove support for --enable-clear-htree; this was only needed during
4442 the early development of the htree patch.
4444 Use Linux-kernel-style makefile output so it is easier to see compiler
4447 Update gettext files to version 0.14.1.
4449 Update to use autoconf 2.5x.
4451 Improved support for compiling e2fsprogs under dietlibc.
4453 Make e2fsprogs portable to Solaris and FreeBSD systems.
4455 Add blkid_verify(), blkid_get_library_version(), and
4456 blkid_parse_version_string() functions to the blkid library.
4458 Add pkg-config files for e2fsprogs's libraries.
4460 Fix "make uninstall" to so that it removes everything that is installed.
4462 Add a configure --enable-maintainer-mode option which enables the
4463 makefile rules to rebuild the configure script from configure.in, and
4464 to reubuild the .gmo files in po directory.
4466 Drop the sparc assembly bitwise operations; it's less efficient
4467 than the GCC 3.4 compile code and triggers compiler warnings on
4468 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
4469 (Addresses Debian Bug #232326)
4472 E2fsprogs 1.35 (February 28, 2004)
4473 ==================================
4475 E2fsck has a new -k option, which in conjunction with the -c options,
4476 preserves the existing badblocks list.
4478 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
4480 E2fsprogs will now deal correctly with symlinks that contain
4481 extended attribute information, which can be created using SE Linux.
4482 (Addresses Debian Bug #232328)
4484 Remove a double longjump into an invalid stack frame bug in e2fsck.
4485 (This was during an abort sequence, which normally worked on Linux and
4486 caused a core dump on other operating systems.)
4488 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
4489 (the NLS library will replace "" with the .po header information).
4491 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4492 dump due to a division by zero error. (Addresses Debian bug #207082)
4494 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4495 when reconnecting a directory requires creating a lost+found
4496 directory. (Addresses Debian bug #219640).
4498 Fixed a bug where e2fsck would bomb out if a journal needed to be
4499 replayed when using an alternate superblock.
4501 E2fsck will give an extra grace period before actually forcing a check
4502 if the laptop is running on battery. The next time fsck runs while
4503 the system is on the AC mains, or after the grace period is exceeded,
4504 the filesystem will be checked. (Addresses Debian bug #205177)
4506 E2fsck will inform the user when there are 5 or fewer mounts before a
4507 filesystem check will be forced. (Addresses Debian bug #157194)
4509 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4510 We now correctly handle the case where there is an overlap between a
4511 block group descriptor or a superblock and a bad block indirect block.
4512 In the case where the indirect block is corrupted, we now suggest
4515 Fix byte swap bugs in e2fsck that caused the journal backup location
4516 in the superblock and symlinks created by SE Linux to be cleared
4517 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
4519 E2fsck -c now replaces the current list of bad blocks with the ones
4522 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4523 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4525 Fix a potential bug in e2fsck which could cause it to core dump when
4526 trying to print the location of the backup superblock.
4528 Protect against a potential core dump in e2fsck when printing a
4529 message about backup superblocks.
4531 Add support for backing up the journal inode location in the
4532 superblock. E2fsck will automatically save the journal information in
4533 the superblock if it is not there already, and will use it if the
4534 journal inode appears to be corrupted. ext2fs_add_journal_inode()
4535 will also save the backup information, so that new filesystems created
4536 by mke2fs and filesystems that have journals added via tune2fs will
4537 also have journal location written to the superblock as well.
4538 Debugfs's logdump command has been enhanced so that it can use the
4539 journal information in the superblock.
4541 E2fsck will now update all superblocks when moving the journal inode.
4543 Shrink the size of the e2fsck executable by moving some initialized
4544 variables to the BSS segment.
4546 E2fsck will avoid printing the ^A and ^B characters which bracket the
4547 progress bar when stdout and stdin are a tty device instead of a pipe
4548 to another program. (Addresses Debian bug #204137)
4550 Debugfs's mkdir command will automatically expand the directory if
4551 necessary. (Addresses Debian Bug: #217892)
4553 Fixed a bug in debugfs so that copying a file from /dev/null uses the
4554 correct mode bits. (Addresses Debian Bug: #217456)
4556 If the environment variables DEBUFS_PAGER and PAGER are not set,
4557 debugfs now searches for the appropriate pager to use, beginning with
4558 /usr/bin/pager, and then falling back to 'more' and 'less'.
4559 (Addresses Debian bug #221977)
4561 Debugfs will now support 2.6 device numbers where the major or minor
4562 number may be larger than 255. (Addresses Sourceforge bug #865289)
4564 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
4566 Chattr now stops processing options when it sees '--'. (Addresses
4569 Fix regression tests so they work correctly when e2fsprogs is compiled
4570 with configure --disable-htree.
4572 Fix bug in uuid library when there is no network card and the library
4573 is generating a time-based uuid. The random MAC address was not
4574 correctly generated to be a multicast address.
4576 Add compile_et extensions from Heimdall that were missed the first time
4579 Fix bug in badblocks when using O_DIRECT; we need to make sure that
4580 we're reading from an offset which is page aligned. For read-only and
4581 read-write tests, we try to recover after an error so that we can
4582 continue reading on page-aligned boundaries. (Addresses Debian Bug
4585 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
4588 Updated and clarified various man pages. (Addresses Debian Bug

4591 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
4593 Fixed various Debian packaging issues (see debian/changelog).
4598 Fixed a build problem so that e2fsprogs would compile with the
4599 --enable-profile option to configure selected. (Addresses Sourceforge
4602 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
4603 Bugzilla Bug #112448)
4605 Centralize code which calculates the location of the superblock
4606 and block group descriptors so that it is in a single library routine.
4608 Added two new functions, ext2fs_file_open2() and
4609 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4611 Fix compile_et to output the correct prototype for
4612 initialize_xxx_err_table_r() in the header file. (Addresses Debian
4615 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4617 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4618 present. This is for when we try stuffing an int into void * pointer.
4620 Fix type-punning which can cause gcc 3.x to miscompile code by getting
4621 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
4622 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4623 **'. The EVMS code uses an ugly union approach since we don't want to
4624 modify the EVMS interfaces.
4626 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4627 aid build process on systems can use invoke GNU make as "gmake".
4629 Added regression testing for mke2fs.
4631 Fixed gcc -Wall nitpicks.
4633 Fixed various compiler warnings.
4635 Add portability fixes for FreeBSD and for using fsctl under Darwin to
4636 support ext2 ioctl's.
4639 E2fsprogs 1.34 (July 25, 2003)
4640 ===============================
4642 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4643 a tight loop while waiting for a child fsck to exit in some cases.
4644 This burns CPU times which slows down the low-level filesystem check.
4646 Added code to mke2fs to assure that the default block size for a
4647 filesystem is at least as big as the sector size of the device, if it
4650 Changed mke2fs and resize2fs to round the default size of a filesystem
4651 to be an even multiple of the VM pagesize in order to avoid a Linux
4652 kernel bug introduced when the storage of the buffer cache was moved
4653 into the page cache.
4655 Mke2fs will warn the user when creating a filesystem with journaling
4656 and a blocksize greater than 4096. (Addresses Debian bug #193773)
4658 Fixed a bug in resize2fs which caused it to fail on filesystems with a
4659 non-empty bad block list. Resize2fs now discards any blocks on the
4660 badblock list which are no longer part of the filesystem as the result
4661 of a filesystem shrink. (Note: this means that shrinking and then
4662 enlarging a filesystem is no longer a reversible operation;
4663 information about bad blocks in the part of the filesystem which is to
4664 be chopped off will be lost.)
4666 Changed resize2fs so the user can use prefixes to specify the units of
4667 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4668 and to make the error and informational messages explicitly display
4669 the blocksize used by the filesystem, in order to avoid confusion.
4670 (Addresses Debian bug: #189814)
4672 Added a new debugfs command, dump_unused, which dumps the contents of
4673 all unused blocks to stdout. (Useful as an emergency try-to-find
4674 deleted data command.)
4676 Added a new debugfs command, imap, which prints the location of a
4677 specified inode in the inode table.
4679 Fixed a bug in the badblocks program which caused it to use one bit of
4680 randomness in its non-destructive read/write test, instead of using a
4681 full 8 bits of randomness.
4683 Added a new option (-t) to badblocks, which allows the user to control
4684 the test pattern(s) used when checking a disk.
4686 The blkid probe function now more correctly detects UDF filesystems.
4688 Fixed a bug in the blkid library which caused it to not update its
4689 cache if a filesystem changes from having a label to not having a
4692 Fixed a bug in the blkid library wihch could avoid an infinite loop
4693 in blkid_find_dev_with_tag() if /proc is not mounted and there the
4694 /etc/blkid.tab file has not yet been created.
4696 Fixed the badblocks program so that the destructive read/write test
4697 honors the -c option, and to use O_DIRECT when possible to avoid
4698 thrashing the system block buffer cache.
4700 Fixed various NLS issues.
4701 - Added Czech and Swedish translations
4702 - Removed testing NYC translation
4703 - Fixed NLS support for message abbrevations in e2fsck
4704 - Remove de-utf.po, since we shouldn't have two versions using different
4706 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
4707 simplify the statistics reporting in e2fsck.
4709 Changed configure.in so that its defaults for *BSD systems no longer
4710 build an fsck wrapper, and not to install in /usr/local by default.
4712 Fixed some minor spelling errors/typo's in e2fsck and the configure
4715 Fixed various Debian packaging issues (see debian/changelog).
4717 Updated and clarified man pages. (Addresses Debian Bug #195616)
4722 Fix gcc -Wall nitpicks.
4724 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4725 NLS support by default. (Added partial workaround for gettext/Darwin
4726 incompatibility problems.)
4728 Added full MIT KRB5 and Himdall compaibility support to the com_err
4729 library and the compile_et program. (Addresses Debian bug #191900)
4731 Added the blkid_known_fstype() function to the blkid library, which
4732 returns true if it is passed a filesystem type which is recognized by
4733 the blkid probing functions.
4735 Improved the documentation for the blkid library.
4737 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4738 returns the hardware sector size of a device, if it is available.
4740 Added a dependency in the blkid library's .so file to the uuid
4741 library, since the former uses the latter. (Addresses Debian bug
4744 Added --with-diet-libc and --disable-evms to the configure script.
4746 Fixed a minor memory leak in the badblocks program.
4748 Fixed a portability problem in tune2fs --- not all systems have strptime().
4750 Fixed a portability problem in debugfs with the use of getopt() more
4751 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
4754 Add support Windows support to ext2fs_get_device_size().
4756 Added (normally disabled) debugging code to the Unix I/O manager which
4757 causes it to disable all userspace caching if the NO_IO_CACHE is
4760 Changed the test I/O manager so it can always be linked into e2fsck,
4761 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4762 configure script. The test I/O manager will only print any debugging
4763 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4764 variables are set, which specifies which I/O operations are logged and
4765 a block number to watch, respectively. The log messages are sent to
4766 stderr by default, unless a filename is specified via the
4767 TEST_IO_LOGFILE environment variable.
4770 E2fsprogs 1.33 (April 21, 2003)
4771 ===============================
4773 Added a new utility program, logsave, which captures the output of a
4774 command in a log file, even if the containing directory hasn't been
4775 mounted yet (in which case the it saves the output in memory until it
4776 can write out the logfile). This is useful for capturing the
4777 output of fsck during the boot sequence.
4779 Fixed some portability problems that were causing problems under
4780 the Cygwin32 environment.
4782 Mke2fs now interprets a negative number to the -b option as a minimum
4785 Fixed a bug in mke2fs which was incorrectly checking the argument to
4786 the -g option if the default block size was used. (Addresses Debian
4789 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4790 it can not find filesystem checkers for jfs, reseirfs, and xfs.
4792 E2fsck now updates the global free block and inode counters from the
4793 block group specific counters quietly. This is needed for an
4794 experimental patch which eliminates locking the entire filesystem when
4795 allocating blocks or inodes; if the filesystem is not unmounted
4796 cleanly, the global counts may not be accurate.
4798 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4799 2.0 is not yet supported; this only pulled in the bug fixes: fixed
4800 possible hangs caused by bugs in calling waitpid, and not setting the
4801 pipe to non-blocking mode; also fixed a file descriptor leak; made
4802 sure all functions call log entry/exit functions.)
4804 Badblocks now flushes its output file as bad blocks are discovered.
4806 The uuid library is now more paranoid about assuming the correctness
4807 of the /dev/random device; it mixes in a stream of bytes from
4808 random/srandom, just in case.
4810 Update Debian files to reflect the fact that I am now the Debian
4811 maintainer of e2fsprogs. Other various Debian-specific packaging
4814 Move the source tarball generation functions from the top-level
4815 makefile to the util/gen-tarball script.
4817 Updated the Turkish .po translation file.
4819 Added Heimdal and MIT krb5 extensions to the com_err library to make
4820 it more compatible with com_err libraries from those distributions.
4822 Changed dumpe2fs to always display the superblock fields relating to
4823 the journalling and/or directory indexing feature even if those
4824 features are not enabled.
4826 Updated and clarify copyright statement vis-a-vis alpha releases of
4829 The ss library will now try to dynamically link to the readline
4830 library and use it if it is present in the system. This means that
4831 the debugfs program now has line editing and history features. The
4832 SS_READLINE_PATH environment variable is used to find a readline or
4833 readline-compatible library.
4835 E2fsck now finds most duplicate filenames (all when rebuilding all
4836 directories via the -D option) and offers to delete or rename
4837 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
4839 Fix bug in e2image. When writing out a raw image file, include data
4840 blocks from symlinks that do not store the symlink within the inode.
4842 Fix bug in resize2fs which incorrectly moved the block and inode
4843 bitmaps for sparse superblock filesystems and incorrectly marked
4844 blocks as in use. (Addresses Debian bug #174766)
4846 Added a new shared library, the blkid library, which efficiently
4847 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4848 and UUID filesystem specifiers without needing to search all of the
4849 devices in the system. Instead, the device is looked up in a cache
4850 file, and then verified to make sure the blkid cache is correct.
4852 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4853 the device name, using the blkid library. (Addresses Debian bugs
4856 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4857 used for spaces in device labels.
4859 Removed 32-bit limitations for debugfs's dump command.
4861 If the user specifies a large number of inodes, Mke2fs will
4862 automatically adjust the number of blocks per group to find a valid
4863 set of filesystem parameters.
4865 Add workaround to detect broken MD devices where when some of the
4866 underlying devices are marked read-only, writes to the MD device are
4867 silently dropped. E2fsck will detect if there is an attempt to run
4868 the journal twice, and abort with an error if this is the case.
4869 (Addresses IBM Bugzilla bug #1226)
4871 E2fsck will print an error if more than one of the -p/-a, -n or -y
4872 options are specified.
4874 E2fsck will fix HTREE corruptions in preen mode, without stopping the
4875 boot process. This is needed because the 2.4 ext2 filesystem
4876 accidentally had the INDEX_FL backwards compatibility code removed.
4878 Mke2fs no longer creates filesystems with the dir_index flag set by
4879 default; the user has to specifically request it.
4881 Update and clarified various man pages. (Addresses Debian bugs
4882 #173612, #175233, #175113, and #170497, #185945, #188318)
4884 Created man page for the mk_cmds program (from the libss library).
4889 Fix various gcc -Wall nits.
4891 Fixed a lot of portability problems that caused e2fsprogs not to build
4892 successfully under Solaris and Apple/Darwin.
4894 Fixed a Makefile dependency to allow building e2fsprogs using parallel
4897 Changes to create a subset distribution which consists only of the
4898 et, ss, uuid, and blkid libraries. The configure script and top-level
4899 makefile were changed to support working with a subset distribution.
4901 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4902 actually used, and might people who are looking for
4903 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4905 Updated debian files to fix a number of Lintian warnings.
4907 Updated config.guess and config.sub with newer versions from the FSF.
4909 Removed unnecessary libraries from being linked into the fsck, lsattr,
4910 chattr, and blkid executables.
4912 E2fsprogs 1.32 (Nomvember 9, 2002)
4913 ==================================
4915 Fixed a bug in the Unix I/O routines which caused needless writebacks
4916 of clean blocks from the unix_io cache (they were erroneously marked
4917 as being dirty, so they were getting written back to disk before
4918 getting evicted from the disk cache). This was harmless, but it
4919 significantly slowed down e2fsck.
4921 Made some other minor optimizations to the Unix I/O routines to save a
4922 small amount of CPU time.
4924 Updated internationalization files.
4927 E2fsprogs 1.31 (Nomvember 8, 2002)
4928 ==================================
4930 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
4931 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
4932 handling for child process that die unexpectly. Add a hack to force
4933 mkfs to create filesystems that won't cause problems with hardware
4934 that has 2k or 4k minimum blocksize requirements. Read from child
4935 processes in non-blocking mode, so that the GUI continues to update.
4937 Fix e2fsck so that it returns the appropriate exit code when the root
4938 filesystem has been changed, so that system's rc scripts will be told that
4939 the system needs to be rebooted.
4941 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4942 was set, some of the descriptor blocks that should have been written
4943 out were getting skipped.
4945 Changed e2fsck to force out changes to the backup copies of the
4946 superblock and block group descriptors when important changes are made
4947 to those data structures.
4949 Fix a bug where e2fsck could erroneously mark a filesystem as being
4950 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
4951 introduced in e2fsprogs 1.28.)
4953 If journal debuging is enabled using --enable-jbd-debug, the debugging
4954 level is now set via the E2FSCK_JBD_DEBUG environment variable.
4956 If byteswapping support is disabled using configure --disable-swapfs,
4957 skip the tests which depend on byte-swapping, so that "make check"
4960 Lshattr will now display the indexed directory flag. Also, some of
4961 the more esoteric compression flags are supressed unless compression
4962 support has been enabled.
4967 E2fsprogs 1.30 (October 31, 2002)
4968 =================================
4970 When resizing a filesystem, and inodes need to moved, resize2fs will
4971 update the inode's ctime field, and the mtime field of the containing
4972 directories, so that incremental backups using dump/restore will work
4975 In order to avoid spurious errors, e2fsck wil check the last
4976 superblock write time to determine whether or not it can safely use
4977 the LOW_DTIME checks to determine if there are inodes on the orphan
4978 inode linked list that had somehow gotten disconnected. (Addresses
4979 Sourceforge bug #620980)
4981 Partition in /proc/partitions that being with the string "lvm" are
4982 considered real partitions even if they do not end with a number.
4984 Fixed a bug in the the uuid generation function, where if /dev/urandom
4985 is not present, but /dev/random is, and there isn't sufficient
4986 entropy, the get_random_byte function could spin a loop forever.
4988 E2fsck, mke2fs, etc. will now reliably notice when image files are
4989 mounted using the loopback interface. (Addresses Sourceforge bug
4992 When flushing buffers (as is done by badblocks, for example) check to
4993 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4994 FDFLUSH ioctl which causes the MD device driver which causes confusing
4995 syslog messages about obselete ioctl messages. (Addresses Sourceforge
4998 Debugfs's write command now checks to see if the destination filename
4999 exists before creating it. (Addresses Sourceforge bug #478195.)
5001 When installing man pages, search for compressed man pages using all
5002 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
5004 Fixed a bug in fsck where multiple filesystems specified on the
5005 command were not being checked in parallel due to a logic bug
5006 introduced to support the FSCK_MAX_INST environment variable.
5008 We have added a new superblock field, s_mkfs_time, which indicates
5009 when a filesystem was created. It is set via mke2fs, and printed out
5010 by dumpe2fs, but is not actually touched by the kernel.
5012 Dumpe2fs has been made more robust by not aborting if there is an
5013 error reading the block/inode bitmaps; instead it will still print out
5014 the location of the block/inode bitmaps and inode table.
5016 Add support for the an alternative block group descriptor layout which
5017 allows for on-line resizing without needing to prepare the filesystem
5018 in advance. (This is the incomat feature flag meta_bg.)
5020 Add support for storing default mount options in the superblock, so
5021 that the filesystem can be mounted with specific mount options without
5022 needing to specify them on the mount command line or in the /etc/fstab
5025 Add support for a new inode flag, which is to be used for indicating
5026 the top of directory hierarchies for the Orlov block allocator.
5028 Fix e2fsck so that if it creates the lost+found directory, it does so
5029 with the more apporpriate permissions of 0700. Also change
5030 mklost+found so that it also creates the directory 0700.
5032 Fixed format bug in e2fsck if NLS is in use.
5034 Add a German translation for e2fsprogs's NLS support.
5036 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
5037 the beginning of the inode table. This won't matter much, since if
5038 there is a bad block at the beginning of the inode table, the root
5039 directory won't be available. But at least e2fsck won't crash in this
5042 Fixed endian problems in the htree code for e2fsck and debugfs.
5044 When byte-swapping a filesystem on a PPC architecture, byte-swap the
5045 bitmaps since the historical big-endian ext2 variant had byte-swapped
5046 bitmaps, and the ext2fs library assumes this. This fixes the
5047 regression test suite on PPC machines.
5049 Fix e2image so that it handles a bad block in the inode table
5052 E2fsck now uses a more sophisticated algorithm to salvage corrupted
5053 directories that recovers more information in the corrupted directory
5056 E2fsck now performs additional consistency checks on indexed (HTREE)
5059 Fix bug where efsck might get confused about whether a completely
5060 empty directory block is an empty leaf block or an interior htree
5061 node. This could cause e2fsck to get confused into think that a valid
5062 indexed directory was corrupted.
5064 E2fsck no longer creates an empty directory entry at the end of a
5065 directory block when optimizing a directory. This would cause some
5066 earlier versions of the dxdir kernel code to corrupt the directory
5067 when attempting to split a node containing an empty directory entry.
5069 E2fsck could sometimes in rare circumstances leave the indexed flag
5070 set after a small directory was optimized by compressing it instead of
5071 indexing it. (This should never happen in real life, since
5072 directories that small wouldn't have been indexed, but better safe
5075 E2fsck now only updates the master superblock in all cases. This
5076 slightly shortens its run time.
5078 Ext2ed can deal with directory entries of length 0; previously it
5079 would get stuck in an infinite loop.
5081 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
5082 specifiers. (Sourceforge patch #613447)
5084 Badblocks will now work correctly on read-only devices such as
5085 CD-ROM's. (Sourceforge patch #600451)
5087 Updated and clarified man pages. (Addresses Debian bug #167108)
5090 E2fsprogs 1.29 (September 24, 2002)
5091 ===================================
5093 Fixed a bug in e2fsck which could corrupt a directory when optimizing
5094 it (via the -D option) or rebuiliding the hash tree index with a 1 in
5095 512 probability, due to a fence post error.
5097 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
5100 Mke2fs now enables the directory indexing flag by default. (Since
5101 this is a compatible feature flag, it's safe to do so.)
5103 Tune2fs will support setting the directory indexing feature flag. It
5104 will automatically set up the default hash algorithm and hash seed
5105 fields in the superblock.
5107 If the bone-headed user enters the root filesystem twice in
5108 /etc/fstab, the -R option which skips the root filesystem will skip
5109 all of them. (Addresses Debian bug #159423). Note! This is not a
5110 precedent for dealing intelligently with any other kind of doubled
5111 entry in /etc/fstab!
5117 Removed perror declaration in lib/et/internal.h. All modern systems
5118 can be expected to define perror() these days. Besides, the lib/et
5119 code wasn't using perror at all anyway. :-)
5122 E2fsprogs 1.28 (August 31, 2002)
5123 ================================
5125 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
5126 for setting the htree flag is not included yet, although it can be
5127 manually turned on via the debugfs program.
5129 Clarified e2fsck error message which is printed when it cannot find
5130 sufficient contiguous block when relcating filesystem metadata.
5132 Added support for building an EVMS plugin module for ext2/3. This
5133 module is substantially the same as the EVMS module shipping with EVMS
5134 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
5135 for use with EVMS 1.0 (which did not include the ext2 plugin module),
5136 if the configure --enable-old-evms flag is given.
5138 Fsck will search through EVMS volumes when trying to resolve
5139 filesystem specifications such as LABEL=xxx or UUID=xxx.
5141 Added a new utility program, /sbin/findfs, which will return
5142 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
5145 Update and clarified various man pages. (addresses Debian Bug #145044,
5146 #146437, #131350, #151990, #144621, #141938)
5148 If there are no filesystems specified on fsck's command line, fsck now
5149 treat that as if the -As options were given. Previously it would
5150 simply do nothing. (Addresses Debian Bug #153102)
5152 Mke2fs no longer treats a failure to be able to clear the MD signature
5153 at the end of the filesystem as a fatal error. (Addresses Debian Bug
5156 The e2p library functions (which are used by lsattr and chattr) now
5157 double check to make sure the file is a regular file or directory
5158 before attempting to use the ext2 ioctls. Some device drivers
5159 unfortunately respond to the ext2 ioctl's with unknown behaviour.
5160 (Addresses Debian Bug #152029).
5162 The extended attribute handling has been updated to correspond with
5163 the latest V2 bestbits ACL code.
5165 Fixed bug in e2fsck which caused it to not clear the dtime field when
5166 processing truncated inodes on the orphan list. This could cause data
5167 loss(!) if a filesystem is rebooted before a truncate has been
5170 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
5171 algorithms. This makes e2fsck much faster in the case of severely
5172 corrupted filesystems where a large number of blocks are claimed by a
5173 large number of inodes. (Thanks to the 2.5 IDE device driver for
5174 inspiring this work.)
5176 Resize2fs has been significantly sped up when shrinking and expanding
5177 a filesystem by a very small number of blocks (for example, when EVMS
5178 is converting a partition to be an EVMS legacy volume).
5180 Added a new option to e2fsck, -D, which will optimize or compress all
5181 of the directories in the filesystem.
5183 E2fsck now catches SIGINT and SIGTERM to make sure it will can
5184 properly clean up and only exit at safe points. Fsck will pass
5185 SIGINT/SIGTERM to its child processes, and wait until they have all
5186 exited before it exits.
5188 The uuid parsing code in the uuid library now properly complains when
5189 an illegally formated uuid is presented to it. (Addresses Debian bug
5192 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
5193 and 2.4.17, since the workaround can cause problems when using a 2.4
5194 kernel with an old version of glibc built with the 2.2 headers.
5196 Fixed a bug in mke2fs where it wasn't properly clearing the initial
5197 superblock used by other filesystems. (Addresses Debian bug #147256.)
5199 Added support for the synchronous directory feature written by Andrew
5202 The debugfs program can delete directories using the rmdir command.
5204 Add support for 8k and 16k filesystems (for systems with page sizes
5205 that are greater or equal to 8k or 16k, respectively). Note that
5206 these filesystems can not be mounted on x86 systems, or other systems
5207 with only 4k page sizes, due to limitations in the current Linux VM
5210 Resize2fs requires that the filesystem state be valid and have no
5211 errors; otherwise, e2fsck -f must be run first. (Previously it simply
5212 required that the last fsck time be greater than the last mount time.)
5214 Configure now defaults the man pages directory to /usr/share/man on
5217 E2fsck now offers to truncate inodes which contain too many blocks (so
5218 that i_blocks would overflow. Also fixed handling of large sparse
5221 E2fsck now more completely checks for symlink validity, including
5222 requiring NULL termination and length checks.
5224 E2fsck will offer to try forcing a disk write to remap a bad block
5225 after finding a read error when reading a filesystem metadata block.
5227 Fixed a bug in debugfs which caused the -b and -s options to crash
5228 debugfs, as well as breaking the testb, setb, and clearb functions.
5230 Added a bmap command to debugfs which calculates the logical to
5231 physical block mapping for a particular inode.
5233 Fixed a bug in code which checked to see if a device was mounted which
5234 sometimes (rarely) failed in the case of a plain file.
5236 Fixed a bug in resize2fs where when it reported an error, it would
5237 print a message erroneously indicating that the filesystem had been
5238 resized before it aborted.
5240 When resizing a plain file which is smaller than the requested size,
5241 resize2fs will attempt to extended the file so that programs like
5242 e2fsck will not complain that the file is too small.
5244 Resize2fs will print the actual new size of the filesystem when it is
5247 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
5248 information on big-endian systems.
5254 Fixed collisions with C++ reserved words.
5256 Added portability fixes for building e2fsprogs on the HURD and AIX.
5258 Added the ext2ed program for creation of test cases. (ext2ed has many
5259 limitations and bugs which make it unsuitable for production use.)
5261 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
5262 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
5263 name_len field is byte swampped on big-endian machines, since in the
5264 V2 structure, name_len is a char field which is doesn't need to be
5265 byte swapped --- except if an old-style kernel had byte-swapped the
5266 name_len field as part of the V1 structure.
5269 E2fsprogs 1.27 (March 8, 2002)
5270 ==============================
5272 The warning messages for mke2fs now go to standard error.
5274 Fixed to make sure "make check" runs all of the test programs with
5275 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
5277 The mke2fs program checks the boot sector for the BSD disk label, and
5278 avoids erasing it if it is there.
5280 Fixed a bug in e2fsck which caused it to core dump if the journal
5281 inode was missing when it was supposed to be there.
5283 E2fsck now prints ranges in pass 5 when printing deltas for the block
5286 Debugfs's "ls -l" command now will print out the file type information
5287 in the directory entry.
5289 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
5290 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
5292 Debugfs can now examine the experimental directory indexing
5295 Fixed bug in debugfs which caused it to core dump if modify_inode is
5296 called without an open filesystem.
5298 The debugfs lsdel command now runs its output through a pager first.
5300 When installing manual pages, remove the compressed manual pages first.
5302 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
5304 Fix the 2.4 resource limitation workaround introduced in 1.26 which
5305 actually broke things on mips32, sparc32, and Alpha platforms.
5307 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
5308 (which is required by the newer libintl libraries).
5313 Fixed various gcc -Wall complaints.
5315 Fixed a few memory leaks in the e2fsck journaling code, and in the
5316 ismounted code checking for a swap device.
5318 Add new inode I/O abstraction interface which exports an inode as
5321 Exported ext2_file_flush as a public interface.
5323 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5325 Lots of small random portability fixes to make e2fsprogs build under
5326 AIX --- even without the 5L compatibility toolkit, and even using the
5327 uber-crippled AIX native C compiler.
5330 E2fsprogs 1.26 (February 3, 2002)
5331 =================================
5333 Dumpe2fs will keep going now if the bad block inode can't be read.
5334 (Previously it stopped with a fatal error.)
5336 E2fsck will now give an opportunity to run the journal even if the
5337 recovery flag is not set. This is the default behaviour if e2fsck is
5338 using a backup superblock, since the needs_recovery flag will never be
5339 set in the backup superblock copies.
5341 E2fsck now automatically finds the backup superblock/group descriptors
5342 even when the primary superblock is completely destroyed for 2k and 4k
5343 filesystems. (Previously it just guessed/assumed that we were dealing
5344 with a 1k filesystem in that case, and users had to manually specify
5345 the backup superblock number.)
5347 Fixed a bug in e2fsck where it dereferences a null pointer when there
5348 is a problem opening a filesystem in preen mode.
5350 E2fsck now handles external journals correctly; previously it trashed
5351 the external journal device if the journal needed to be replayed.
5353 Work around ulimit incompatibility problem caused by recent 2.4
5354 kernels; the unix IO module will automatically try to set any resource
5355 limits to be infinite on startup.
5357 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5358 bitmap if it wasn't present and the blocksize was 2k or 4k.
5359 (Addresses Debian Bug #116975)
5361 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5362 clearing the new V2 fields if they do not make sense or if the ext3
5363 superblock is version 1 superblock.
5365 E2fsck will automatically relocate the ext3 journal from a visible
5366 file (i.e., /.journal) to an hidden inode if the filesystem has been
5367 opened read/write. This allows the users to add a journal while the
5368 filesystem is mounted, but the next time the system is rebooted, the
5369 journal file will disappear. This avoids problems with backups,
5370 stupid operators with superuser bits, etc.
5372 Fix a bug in fsck where it would not support a filesystem type of
5373 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5375 Fsck now supports fstab entries of the form "ext3,ext2". It will also
5376 automatically identify reiserfs filesystems.
5378 The number of processes spawned by fsck can now be limited using the
5379 FSCK_MAX_INST environment variable.
5381 Fsck now searchs the LVM proc hierarchy to find logical volumes which
5382 should be searched for UUID and label information.
5384 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5385 limit if at all possible, when opening a block device. (The filesize
5386 limit shouldn't be applied against writes to a block device.)
5388 In mke2fs and e2fsck, specifying the -c option twice will now do
5389 a read/write test on the disk. Update the man pages to encourage
5390 using the -c option, and to discouraging running badblocks separately,
5391 since users tend to forget to set the blocksize when running
5394 Mke2fs now automatically clears the immutable attribute on a
5395 pre-existing .journal file left over from a previous failed attempt to
5396 add a journal to an alreadyy-mounted filesystem.
5398 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
5401 Mke2fs now creates the lost+found directory with permissions of 0700,
5402 so that files that had previously lived in protected directory are
5403 safe if they get dropped in lost+found and the system administrator
5404 doesn't deal with immediately. (Addresses Debian #bug 118443)
5406 Mke2fs and e2fsck (and all programs that use the
5407 ext2fs_check_if_mounted function) will now properly identify that a
5408 device is mounted, even in cases where devfs has confused things with
5409 multiple devices names with the same identity, or if a dim-witted
5410 system administrator has done something stupid like creating device
5411 file aliases in their home directory. Also now checks for swap devices
5412 by using /proc/swaps. (Addresses Debian bug #106622)
5414 Added a new option (-T) to tune2fs which sets the time a filesystem
5417 Speed up e2image when creating sparse raw image files by optimizing
5418 away excess lseek() system calls.
5420 Fix support of large (> 2GB) files when used as a filesystem in
5421 mke2fs, tune2fs, debugfs, and findsuper.
5423 Debugfs's stat and icheck commands now properly deals with large (>
5426 Debugfs's set_super_value command now prints out the list of valid
5427 superblock fields which can be set using the command.
5429 Debugfs's rm and kill_file command now updates the superblock free block
5430 and inode counts, thus keeping the filesystem consistent.
5432 Debugfs's lsdel command now takes an optional argument which allows
5433 the user to only see the most recently deleted files.
5435 A new command (undel) was added to debugfs which automates
5436 undeleting a deleted inode and linking it back to a directory.
5438 Debugfs's ls command now takes a new option, -d, which lists
5439 deleted directory entries.
5441 Debugfs's testb, freeb, setb, and find_free_block commands now take an
5442 optional count argument.
5444 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5445 be used to signal that a particular inode should not be eligible for
5446 tail-merging --- this is needed for programs like LILO.
5448 The findsuper (an unreleased, uninstalled utility program) has been
5449 improved to add extra validity checks and to add a progress meter.
5450 (It is still an unsupported program; the officially supported way to
5451 recover from a trashed partition table is to use gpart; findsuper is
5452 for wizards only. :-)
5454 Debugfs was fixed to compile with "configure --disable-swapfs".
5456 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
5458 Added new translation file for Turkish.
5463 Fix general gcc -Wall complaints.
5465 E2fsprogs (mostly) works with the dietlibc.
5467 The programming texinfo file has been expanded to include description
5468 of additional libext2fs functions. (Still not compeltely done, but a
5469 lot of the more important functions have been documented.)
5471 Added a umask structure to struct_ext2_filsys, which currently only
5472 modifies the behaviour of ext2fs_mkdir(), but if we add any file
5473 creation functions to libext2fs, we should also make sure they respect
5476 The build-rpm script was fixed to be a bit more safe.
5478 The tests' Makefile now has a way of automating test case creation
5479 for e2fsck, using "make testnew".
5481 Created a new function, ext2fs_dir_iterate2 which passes more
5482 information to the callback function (identical to the one used by
5483 ext2fs_dblist_dir_iterate). The directory iterator functions take a
5484 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5485 directory entries. If the directory entry is deleted, the callback
5486 function will be called with the entry paraemter set to
5487 DIRENT_DELETED_FILE.
5489 Added new functions, ext2fs_inode_alloc_stats and
5490 ext2fs_block_alloc_stats, which takes updates block/inode allocation
5491 statistics in the bitmaps, block group descriptors, and superblock
5492 when inodes or blocks are allocated or deallocated.
5495 E2fsprogs 1.25 (September 20, 2001)
5496 ===================================
5498 This is primarily a bug-fix release; no new features were added, but
5499 there are a number of embarassing bug fixes and cleanups applied.
5501 Fix a bug mke2fs which causes stack garbage to be written to disk when
5502 zapping disk sectors. (This bug could cause mke2fs to core dump for
5503 some kernels, I suspect with security enhancement patches.)
5505 Remove unneeded #include of <linux/config.h> which was breaking
5506 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
5508 Updated tune2fs man page to reflect the fact that adding or removing a
5509 journal doesn't require running e2fsck.
5511 Remove use of AC_REQUIRE from autoconf which had been used to prevent
5512 AC_CANONICAL_HOST from being called twice; unfortunately this causes
5513 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5514 used outside of autoconf macros. Fortunately, it doesn't seem to be
5515 necessary any more, anyway.
5517 E2fsck will now not fall back to an alternate superblock if the user
5518 specifies the superblock location explicitly on the command-line.
5519 This allows easier recovery from a situation where the primary
5520 superblock and block groups are slightly corrupted, but the backup
5521 superblocks are completely broken.
5523 Fix problem which caused compile_et and mk_cmds to blow up if
5524 e2fsprogs was in a directory with a pathname that contained spaces.
5526 We are now more paranoid about checking the entry in /etc/mtab to make
5527 sure the filesystem is really mounted, since some broken distributions
5528 (read: Slackware) don't initialize /etc/mtab before checking non-root
5529 filesystems. (Slackware also doesn't check the root filesystem
5530 separately, and reboot if the root filesystem had changes applied to
5531 it, which is dangerous and broken, but there's nothing I can do about
5534 Make UUID library C++ friendly by adding appropriate extern "C"
5535 declarations and using const in the function declarations.
5537 Fix up the com_err texinfo file so that it can product a valid info
5538 file (previously, it could only be used to generate paper
5539 documentation using texinfo.tex).
5542 E2fsprogs 1.24a (September 2, 2001)
5543 ===================================
5545 Fix brown-paper bug in mke2fs which caused it to segfault when
5546 printing the version string.
5549 E2fsprogs 1.24 (August 30, 2001)
5550 ================================
5552 Revert the BLKGETSIZE64 support, since for some distributions, this
5553 ioctl has been used by an unofficial kernel patch to update the last
5554 sector on the disk, and this was causing disk corruption problems as a
5557 Mke2fs is now more careful about zapping swap space signatures and
5558 other filesystem/raid superblock magic values so that programs like
5559 mount who try to use hueristics to determine the filesystem type of a
5560 partition are less likely to be confused.
5562 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5563 regular file (since Andreas Dilger's on-line resizing tools will set
5566 Fixed some minor texinfo, man pages nits for spelling errors,
5567 texinfo warnings, etc. (Addresses Debian bug #110621.)
5569 E2fsprogs program no longer print the filesystem version number
5570 (i.e. 0.5b), since it only confuses people and doesn't serve any real
5573 E2fsck will once again compile under libc5, since it will supply its
5574 own version of strnlen if necesssary.
5576 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5577 when specifying the external journal device. tune2fs will also search
5578 devices looking for the externla journal debice when removing.
5580 E2fsprogs 1.23 (August 15, 2001)
5581 ================================
5583 Add initial support for extended attributes (EA); e2fsck will
5584 correctly handle a filesystem with EA's and check the EA blocks for
5587 E2fsck's symlink sanity checking has been cleaned up. It now checks
5588 the i_size value of fast symlinks, and checks for immutable flags
5589 being set of symlinks, etc.
5591 E2fsck now offers to clear inodes which are special files that have a
5592 non-zero i_blocks or i_size field. (The i_size field check was in the
5593 previous version of the code, but due to a bug it didn't offer to
5594 clear the inode unless i_size and i_size_high were both non-zero.)
5596 E2image can now create "raw" image files, which only contain the
5597 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5598 debugfs, etc., can be run directly on the raw image file.
5600 Add support for the 64-bit block device patches.
5602 Fixed bugs in creating external journals with a 1k blocksize.
5604 Add initial support for external journals (so long as the external
5605 journal only supports a single filesystem) in e2fsck.
5607 Remove requirement for needing to run fsck on a filesystem after
5608 removing a journal (either internal or external).
5610 The man pages now document how to create and manage external journals.
5612 Speed up the check of an ext3 filesystems by avoiding a needless flush
5613 of all of the superblock and block group descriptors.
5615 Speed up creating an internal journal using tune2fs in the case where
5616 the filesystem has a lot blocks already allocated.
5618 Tune2fs has been fixed to make sure that only error messages go to
5619 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5621 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5622 now not set the sparse_super feature. (Addresses Debian bug #108165)
5624 Add support in fsck for the filesystem type "auto".
5626 Fsck -A will not try to interpret device names for filesystems which
5627 have a pass number is 0. (Addresses Debian bug #106696).
5629 Fsck prints a warning message if now valid filesystems are passed to
5630 it. (Addresses Debian Bug #107458.)
5632 E2fsck now gives an explicit warning if there filesystem still has
5633 errors at the end of the run. (Addresses Debian bug #104502)
5635 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5636 reflects an error. E2fsck will also not run the orphan list if the
5637 filesystem contains errors, since the orphan list might be corrupted.
5639 E2fsck now prints the number of large files when given the -v option.
5641 Fixed minor memory leaks in e2fsck.
5643 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5646 E2fsprogs 1.22 (June 22, 2001)
5647 ==============================
5649 Fixed a bug in e2fsck's handling of orphan inodes which are special
5650 files (i.e., block/character device files, named FIFO's, etc.).
5652 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5653 tune2fs to fail at adding a journal to a mounted filesystem.
5655 Fixed a few big-endian bugs in e2fsprogs
5656 * The directory block functions were accidentally reporting
5657 some directories as corrupted when they weren't.
5658 * If e2fsprogs is compiled --disable-swapfs, the C language
5659 equivalents weren't being included for big-endian platforms.
5660 (Fixes Debian bug #101686).
5662 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
5667 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5668 ioctls, and allow them to be defined for non-i386 platforms.
5670 The uuid.h header file is now protected against multiple inclusions.
5672 E2fsprogs is now being developed using BitKeeper. Changed the test
5673 scripts to deal with BK's stripping CR characgters from text files,
5674 and changed the top-level Makefile.in to avoid including BitKeeper
5675 files when generating the source tarball.
5678 E2fsprogs 1.21 (June 15, 2001)
5679 ==============================
5681 Added new configure flags which allow a subset e2fsprogs to be built;
5682 this is most useful for boot floopies, since the resulting shared
5683 libraries and programs are slimmed down by removing features that
5684 aren't necessary for a boot floppy. The new flags that were added
5685 are: --disable-swapfs, which removes support for byte swapping old
5686 legacy PPC/68k filesystems, --disable-debugfs, which removes support
5687 for debugfs from the libext2fs library, --disable-imager, which
5688 removes support for the e2image program, and --disable-resizer, which
5689 removes support for resize2fs.
5691 E2fsck now prints the number of mounts or days elapsed since the last
5692 check when e2fsck is forced to check an otherwise clean filesystem.
5694 Tune2fs now prints an informative message about how often a filesystem
5695 will be checked when adding a journal to the filesystem, to remind the
5696 user that he/she may want to adjust those parameters using tune2fs
5699 Worked around hurd brain-damage which causes e2fsck to sometimes
5700 believe a filesystem is the root filesystem based on device numbers
5701 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5704 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5705 erroneous error with the -F option was specified.
5707 Fixed a ext3 recovery bug in the revoke handling; synchronized with
5710 Fixed two bugs in e2fsck's handling of dup block handling, dealing
5711 with relatively uncommon edge cases: a directory with an indirect
5712 block which is claimed by another file, and when the last inode in the
5713 filesystem has blocks claimed by another file.
5715 E2fsck now checks to see if the i_size field of a fast symlink is too
5716 big, and offers to clear the symlink if so.
5718 E2fsck now checks to see if i_size_high of special files is non-zero,
5719 and offers to clear i_size_high.
5721 Fix e2fsck's handling of incompatible journal flags so that the user
5722 has chance to abort, and then has the option to clear out the journal
5723 entirely. (Addresses Debian bug #98527.)
5725 Fixed a bug in fsck which could cause it to core dump if a mix of
5726 standard and non-standard device names are used in /etc/fstab.
5727 (Debian bug #100559)
5729 Fixed a bug in debugfs which caused read errors when copying a file to
5732 The debugfs set_super_value command can now modify the s_lastcheck field.
5734 Fixed a bug in lsattr and chattr which was accidentally introduced in
5735 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
5736 directories correctly because the change modified the layout of struct
5737 dirent to be incompatible with the libe2p shared library.
5739 Cleaned up the mke2fs manual page and included a discussion about why
5740 it's good to periodically check the filesystem even when journaling is
5746 Fix general gcc -Wall complaints.
5748 The types needed by the ext2 header files are now provided by
5749 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5751 Integers are now preferred to longs when trying to find a 32-bit type
5752 in ext2_types.h. Also, if linux/types.h has already been defined,
5753 don't try to redefine the types.
5755 Fixed make depend script so that it automatically corrects the
5756 pathname cleanups performed by make -M, so I don't have to fix them up
5759 Fixed the d_loaddump test case to be more robust, and not depend on
5762 Removed debugfs's dependence on pread(), which was accidentally
5763 intrudced in e2fsprogs 1.20
5765 Fixed a performance bug in the libext2fs's icount routine; the size
5766 estimate of the icount array was incorrectly being calculated.
5768 Removed use of the badblocks compatibility functions in the e2fsprogs
5771 Added paranoia code which protects against strange cases where /etc
5772 isn't on the root filesystem, or if /etc/mtab doesn't exist.
5774 The header file ext2_types.h is now installed.
5776 Autoconf is used to determine when we are on big-endian machines,
5777 instead of doing run-time tests, to save a few bytes of code.
5779 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5780 functions are no longer inline functions, which saves space and
5781 doesn't really cost any real performance.
5783 The ext2fs library no longer depends on the e2p library. (What need
5784 there was of it --- namely, fsetflags, was coded in-line).
5786 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5787 when the user is stupid and tries compiling the package using "make
5790 Miscellaneous code cleanups:
5791 * Added missing files from Makefile.in's SRCS file, so that
5792 their dependencies would be properly calculated.
5793 * Removed redundant code
5794 * Fixed comments in code
5795 * Removed no-longer unneeded argsused #pragma.
5798 E2fsprogs 1.20 (May 20, 2001)
5799 =============================
5801 Add support for replaying the ext3 journal purely in user mode,
5802 including handling the orphaned inode list. Used code contributed by
5803 Andreas Dilger, with bug fixes and the orphaned inode handling done
5806 The mke2fs and tune2fs programs can create or modify a filesystem to
5807 include an ext3 journal. Tune2fs also can be used to remove an ext3
5808 journal from a filesystem.
5810 E2fsck will now check for the existence of a linked list of orphan
5811 inodes in the superblock, and clear those inodes before starting the
5812 rest of the filesystem check (but after the journal playback).
5814 E2fsck now validates the file descriptor passed to the -C option,
5815 which saves against the completion bar getting written to an
5816 unexpected location, such as the disk being checked. (Debian
5817 bug/wishlist #55220)
5819 E2fsck will now bump the filesystem revision number from zero to one
5820 if any of the compatibility bits are set.
5822 Fixed a bug where a badly corrupted directory on a big endian system
5823 could cause e2fsck to die with a bus error. The
5824 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5825 the ext2 library now does alignment sanity checks on the rec_len field
5826 of the directory entry before using it.
5828 The ext2 library has been enhanced to make tune2fs safe to run on
5829 mounted filesystems. (Users could usually get away with using tune2fs
5830 on mounted filesystems before, but with the advent of ext3 and
5831 journaling, it became important to make tune2fs was *really* safe for
5832 use even when the filesystem being modified is mounted.) E2label is
5833 now implemented by tune2fs using an argv[0] dispatch, so that e2label
5834 is also now safe for use on mounted filesystems.
5836 Added a new program, e2image, which creates a backup of critical ext2
5837 filesystem data structures. The generated image file can be examined
5838 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
5839 the image file to help recover very badly damaged filesystems.
5841 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5842 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
5843 large file when deciding whether or not the filesystem has large files.
5845 Fixed lsattr and chattr so that they work correctly on large files.
5846 (Fixes Debian bug #72690.)
5848 Removed limitation in get_device_size() which imposed a one terrabyte
5849 filesystem limitation. (Most 2.2 kernels still have a signed int
5850 problem which cause 1 TB block device limitation. Fortunately, the
5851 kernel patches to fix this are much easier than fixing the 2TB
5852 limitation in the kernel. :-)
5854 A max_mount_count of zero is now treated as if no mount count were
5855 set. (Previously, no mount count was indicated by using -1, and a
5856 mount count of zero caused e2fsck to always be run.)
5858 Mke2fs supports two new filesystem types largefile and largefile4.
5860 Mke2fs now adds some randomness in s_max_mount_count so that multiple
5861 filesystems won't be all checked at the same time under normal
5864 Fixed bug in the progress bar printing code which could cause e2fsck
5865 to core dump on an illegal filesystem.
5867 Fixed bug in fsck which could allow more than one instance of e2fsck
5868 to be printing a progress bar. (Debian bug #65267)
5870 Fsck using a UUID or a LABEL specifier will work even if devfs is
5871 compiled into the kernel and not mounted. If the pathnames in
5872 /proc/partitions are incorrect, fsck will search /dev for the correct
5873 device (using the new ext2fs_find_block_device library function).
5874 Fsck now also checks the RAID devices first so that they are properly
5875 found when they are in use. Support has also been added to support
5876 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
5878 Fixed a bug in fsck which caused it not deal properly with 16
5879 byte long filesystem labels.
5881 Fsck's -t option has been made a lot more flexible. The semantics for
5882 what happens if a comma-separated list to fsck has been regularized,
5883 and it is now possible to filter what filesystems will get checked
5884 based what is in the filesystem's fstab entry's option field. (Debian
5887 The dumpe2fs program can now print out the group description
5888 information in hex, and also prints the location of the superblock and
5889 block group descriptor for those block groups that have them.
5891 Mke2fs now clears the ext2 superblock before it starts creating a
5892 filesystem, so that the superblock magic number is only written if the
5893 filesystem creation process successfully completes.
5895 The debugfs program's stat command now pretty-prints the blocks used
5896 by an inode so that it's more compact and informative.
5898 The debugfs stats command now uses the same libe2p code (which is used
5899 by dumpe2fs) to print the superblock header information. This is more
5900 complete, and it avoids a bit of code duplication.
5902 Added a new debugfs command, set_super_value (ssv) which allows the
5903 user to set arbitrary superblock fields.
5905 Debugfs was extended to support inode numbers in hex (by prefixing
5906 them with 0x), and so that modify_inode can set the inode generation
5907 number. Also, there is now a new function command called logdump
5908 which will dump an ext3 journal.
5910 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5913 Debugfs's dump command now stops immediately upon reporting a disk
5914 read error. (Fixed a bug in ext2fs_file_read library routine which
5915 caused debugfs not to stop.) (Debian bug #79163)
5917 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5918 checked before /etc/mtab is used, since /proc/mounts is more likely to
5921 Added portability fixes for Solaris and Linux/ia64.
5923 Various manual pages were clarified and cleaned up. (Fixed debian
5924 bugs #63442, #67446, and #87216)
5930 The e2fsck message printer now supports %Iu and %Ig, which will print
5931 out the inode's user and group owners, respectively.
5933 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5934 that no longer dependent on the system having the correct version of
5935 the kernel header files.
5937 Added a new function to libext2, ext2fs_find_block_device(), which
5938 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5939 device given its device number.
5941 Added a new function to libext2, ext2fs_sync_device, which centralizes
5942 all of the places which might try to use the BLKFLSBUF or FDFLUSH
5943 ioctls (and usually failing to define them since the system header
5944 files don't usually do this for us, and we're trying to avoid usage of
5945 kernel include files now).
5947 Added new utility programs in tests/progs: random_exercise and
5948 hold_inode. They aren't built by default; they're useful for
5949 exercising ext3 filesystem code.
5951 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5952 the filesystem close functions to only update the superblock, and to
5953 not touch the block group descriptors. Needed by tune2fs when
5954 modifying a mounted filesystem.
5956 Got rid of struct ext2fs_sb and replaced it with the standard struct
5957 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
5958 source (but not binary) compatibility of some users of the ext2
5959 library. Those applications should just simply do a global search and
5960 replace of struct ext2fs_sb with struct ext2_super_block, and include
5961 the new header file <ext2fs/ext2_fs.h> which defines it.
5963 The ino_t type has been renamed ext2_ino_t to protect applications
5964 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5965 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
5966 unexpected ABI change.
5968 The Makefiles have been reworked so that "make check" can be run from
5969 the top-level Makefile.
5971 Fix general gcc -Wall complaints and removed dead code.
5973 Remove use of NOARGS, because we assume everyone does ANSI C these
5976 Added build-rpm script from sct.
5978 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
5981 New function ext2fs_flush_icache which must be called if the
5982 application program modifies the inode table blocks without going
5983 through ext2fs_write_inode() interface.
5985 New ext2fs_check_mount_point() function, which will return the mount
5986 point of a device if mounted.
5988 The io_channel abstraction now has an optional interface,
5989 io_channel_write_range, which allows specific byte ranges to be
5992 The unix_io IO channel now supports write-through caching, so that
5993 journal creation is more efficient.
5995 Added x86 assembly language routines to support byte swapping, to
5996 reduce executable size.
5998 Fixed bug in the utility program subst so that it's possible to
5999 replace a substitution variable with a zero-length string.
6001 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
6002 slipped into some of the problem number.
6004 E2fsprogs 1.19 (July 13, 2000)
6005 ==============================
6007 Release the resize2fs program since the timeout before it could
6008 be released under the GPL has finally expired.
6010 Add experimental support needed for the ext2 compression patches.
6011 This requires compiling e2fsprogs with the --enable-compression flag
6012 to the configure script.
6014 Added ext3 journalling support. E2fsck will run the journal (if
6015 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
6016 installed as a symlink to e2fsck. Fsck has been taught about ext3,
6017 and treats it the same as ext2 in terms of the progress bar logic.
6018 Dumpe2fs will display the superblock journaling information if the
6019 filesystem has a journal. The ext2 library will now permit opening an
6020 ext3 filesystem with the recovery flag set. This is necessary for
6021 on-line dump's to work correctly, but there may be issues with this
6022 working well since ext3 is much less agressive about syncing blocks to
6023 the filesystem, since they're safe on the journal.
6025 Tune2fs and e2fsck have been changed to allow the mount_count check to
6026 be disabled by setting max_mount_count to -1. (This was already
6027 supported by the kernel.)
6029 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
6030 are used for ext3 as well.
6032 Added internationalization support for e2fsprogs; must be enabled
6033 by passing --enable-nls to configure.
6035 Always use the provided ext2fs header files to insulate ourselves from
6036 kernel version changes. Which include files are used by e2fsprogs
6037 have also been cleaned up to improve portability.
6039 Limit the number of times that e2fsck updates the progress bar so that
6040 people who are booting using a 9600 baud console don't get swampped by
6043 Improved the loop detection algorithm in e2sck's pass #3 so that it is
6044 much, much faster for large filesystems with a large number of
6047 The memory footprint for e2fsck is now slightly smaller than before.
6049 E2fsck now checks if special devices have a non-zero size, and offers
6050 to clear the size field if it finds such an inode.
6052 E2fsck now checks if special devices have the append-only flag set,
6053 and offers to clear the inode.
6055 E2fsck now properly handles some "should never fail" cases during a
6056 bitmap copy in pass5.
6058 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
6060 E2fsck now calculates the correct location of the backup superblock in
6061 the case of filesystem blocksizes > 1k.
6063 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
6064 which normally didn't cause problems under most filesystem parameters,
6065 but could cause a valid superblock to be rejected in extreme cases.
6066 Other checks for validating superblock values were made more
6069 Added non-destructive write testing to the badblocks program, courtesy
6070 of David Beattie. The badblocks also now has an option to input the
6071 current set of bad blocks, so that known bad blocks are skipped to
6072 speed up the badblocks test. There is also a persistent rescan
6073 feature which causes badblocks to run until it has completed some
6074 number of passes without discovering any new bad blocks.
6076 Badblocks now checks to see if the device is mounted and refuses to do
6077 the tests involving writing to the device if it is mounted. Also,
6078 badblocks now allows the number of blocks to be checked to be
6079 defaulted to the size of the partition.
6081 Fixed a bug in fsck which didn't allow non-root users to be able to
6082 check filesystems if there were any LABEL= or UUID= entries in
6085 The Hurd doesn't support the filetype filesystem feature. The mke2fs
6086 program now makes sure that for the Hurd, the filestype feature is
6087 turned off. E2fsck will check to see if the filetype feature is
6088 turned on for Hurd filesystems, and offer to turn off the feature.
6090 Mke2fs now has a safety check to make sure the number of blocks do not
6091 exceed 32 bits even on a 64 bit platform.
6093 Really fixed a bug in fsck to allow "fsck -As" to run interactive
6094 fsck's. (For those people who like to do interactive fsck's in the
6097 Debugfs has a few new features: the rdump command, which will do a
6098 recursive dump of a directory and all of its contents, and the lcd
6099 command which does a local chdir (much like the ftp command of the
6100 same name). In addition, the debugfs program and the open_filesystem
6101 command now takes three new options: -b and -s, which allows the
6102 blocksize and superblock location to be specified, and the -c option
6103 which is used in catastrophic situations where the block group
6104 descriptors are corrupt. If the -c option is specified, debugfs will
6105 skip trying to read in the block and inode bitmaps.
6107 Debufs's lsdel command was fixed to handle bad blocks in the inode
6110 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
6113 General improvements in error messages
6115 - Mke2fs prints a sane error message if the partition size is zero
6116 (usually because the partition table wasn't reread by the
6117 kernel due to the partition being busy), instead of "invalid
6118 argument passed to ext2 library while initializing superblock".
6120 - Fsck now prints more self-explanatory message if an invalid UUID=
6121 or LABEL= specification is passed to it.
6123 UUID library changed to use the LGPL.
6125 Fixed a bug in the UUID library where very rapid calls to the
6126 time-based UUID generator could cause duplicate UUID's to be returned.
6127 This was not a problem for e2fsprogs, but it could be a problem for
6128 other users of the library.
6130 Make the UUID library more robust in the face of missing or an
6131 improper /dev/urandom or /dev/random files.
6133 Added some random portability fixes for Solaris.
6135 Some minor man page updates.
6137 Fixed a memory leak in the ss library.
6143 We now try to use lseek64 and open64 from the LFS if possible.
6145 The 3rd parameter in e2p's print_flags is now a flags word, instead of
6148 The mark and unmark bitmap functions now return the previous state of
6149 the bit that was being changed, which is useful for some speed
6152 The following functions have been added to enhance the badblocks list
6153 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
6154 ext2fs_badblocks_equal.
6156 The ext2 header files now have the latest journalling fields to the
6159 The ext2fs_mkdir function in libext2fs now properly backs out of error
6160 conditions robustly.
6162 Cleaned up makefiles:
6163 - to cleanly compile with the -j flag.
6164 - so distclean removes all generated files.
6165 - so in case of an error while installing header files, the make aborts.
6167 Fix test_script so that it works correctly when compiling in the
6170 The random UUID generation routine has been made slightly better in
6171 the case where /dev/random doesn't exist. (Use of randomly-based UUID
6172 is still not recommended if /dev/random doesn't exist, however; it's
6173 better to use the time/ethernet MAC address UUID in this case.)
6175 Clean up the build process so it's more friendly in case of missing
6178 The ext2fs header file can now be #include'd into C++ programs.
6180 The e2p.h header file is now installed.
6182 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
6186 E2fsprogs 1.18 (November 10, 1999)
6187 ==================================
6189 Fix a core dumping bug in e2fsck if an imagic inode is present or
6190 (more rarely) if the filesystem is badly corrupted enough that e2fsck
6191 has to restart pass 1 processing. E2fsck now closes the filesystem
6192 before freeing a large number of its data structures, so in the case
6193 of future memory faults, at least the fixed filesystem will be fully
6196 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
6197 imagic inode, it will offer to clear the imagic flag.
6199 E2fsck will now offer to clear the immutable flag on special files
6200 (device/socket/fifos) when running it in non-preen mode.
6202 E2fsck will now set the filetype when creating /lost+found, and when
6203 connected orphaned inodes to /lost+found.
6205 Debugfs's ncheck and icheck commands now handles the case where there
6206 are bad blocks in the inode table without bombing out.
6208 The badblocks list processing code has been made more efficiently for
6209 appending a large number of (ordered) badblocks to the badblocks list.
6211 Some minor man page updates.
6213 Fsck now allows interactive e2fsck's when using fsck -As (not a common
6214 mode, but some people like to do this in boot scripts for silly reasons).
6219 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
6220 with the problem code convention.
6222 The badblocks list regression test program has been updated to work
6223 with previously made API name changes.
6225 The ext2fs_free() command now uses the new badblocks API to avoid
6226 using the compatibility layer.
6228 Added new regression test cases; the run_e2fsck test script now
6229 supports the ability for a test case to run a prepratory command
6230 before running e2fsck.
6232 E2fsprogs 1.17 (October 26, 1999)
6233 =================================
6235 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
6238 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
6239 thus potentially causing problems if a binary UUID contained a NULL
6242 E2fsck now uses stricter checks for directory entries in pass 2:
6243 zero-length filenames are not allowed; neither are 8 byte long
6246 The debugfs "dirty" command now clears the filesystem valid bit.
6247 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
6248 bit in the in-core superblock image. The new functionality is more
6249 what the user expects, and is more useful.)
6251 Added a debugging hook to test parallel fsck; if the environment
6252 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
6253 will be checked in parallel when they normally would not be.
6258 Fixed some #ifdef's for compilation under the Hurd OS.
6260 Fixed minor W2K compatibility problems.
6262 Fixed some miscellaneous GCC warnings.
6265 E2fsprogs 1.16 (October 22, 1999)
6266 =================================
6268 Fixed a race condition bug in fsck; when printing a progress bar, if
6269 checking multiple filesystems in parallel, it was possible for fsck to
6270 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
6271 handler, which would cause it to terminate with a signal 10.
6273 E2fsck now properly handles filesystems that have the
6274 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
6275 filesystem into using or not using FILETYPE feature.
6277 E2fsck now properly handles filesystems that have the IMAGIC feature
6278 turned on (this is used on Linux AFS servers).
6280 The mke2fs program now creates filesystems that have the filetype and
6281 sparse_superblock features enabled by default, unless it is run on a
6282 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
6283 so there is now a new flag -O which allows the user to specify with
6284 which features she would like to create the filesystem; "mke2fs -O
6285 none" will create a filesystsem compatible with 2.0 kernels.
6287 The tune2fs program now has a -O option which allows the user to set
6288 and reset "safe" filesystem features. Currently, the only ones which
6289 allows to be modified are the filetype and sparse_superblock features.
6290 Note setting or clearing either feature will require running e2fsck on
6291 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
6292 requires that there is enough free space on the filesystem for the
6293 extra superblocks which will be created by e2fsck.)
6295 Debugfs can now set and print filesystem features in the superblock
6296 using the "features" command. Dumpe2fs will print out the complete
6297 set of features when listing the superblock.
6299 Dumpe2fs has new options -f (force) and -h (header-only).
6301 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
6302 message to come up. This could happen when decrementing or
6303 incrementing a link count could result in an overflow.
6305 Fixed a bug in e2fsck where the block count on the lost+found
6306 directory would not be properly incremented when the directory was
6307 expanded to the point where an indirect block needed to be allocated.
6309 E2fsck now makes some additional sanity checks on the superblock to
6310 avoid crashing or giving a memory allocation error if some of the
6311 values in the superblock are unresonable (but the superblock otherwise
6314 Fixed a bug in e2fsck where a very badly corrupted filesystem might
6315 require two passes to completely fix the filesystem. This happened if
6316 an inode claimed blocks that was part of the filesystem metadata
6317 (typically, when garbage was written into an inode table or indirect
6318 block, since this kind of filesystem corruption normally doesn't
6321 On the Alpha, glibc declares st_flags although it isn't actually used;
6322 the configure script was improved to detect this case so that
6323 e2fsprogs can avoid using the non-functional stat field.
6325 The manual pages were updated to use a more consistent formatting
6326 style consistent with standard Unix man pages. Mke2fs's man page
6327 added documentation for a few previously undocumented options.
6329 Fixed minor display bugs in tune2fs and mke2fs.
6334 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6336 Added features to parse and print feature strings into the e2p library.
6337 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6339 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6340 whose directory entries contain proper filetype information if the
6341 filesystem supports it.
6343 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6344 the directory entry filetype information. This is used to set the
6345 directory entry filetype information if the filesystem supports it.
6347 Fixed a bug in ext2fs_expand_dir() where the block count in a
6348 directory's inode would not be properly incremented when the directory
6349 was expanded to the point where an indirect block needed to be
6353 E2fsprogs 1.15 (July 18, 1999)
6354 ==============================
6356 Add configuration checks so that e2fsprogs will compile cleanly on
6357 Linux 2.3 kernels that have renamed i_version to i_generation.
6359 E2fsck now prints a progress/completion bar (and not just a simple
6360 spinner) if the -C0 option is requested or if it receives a SIGUSR1
6361 signal. Fsck will automatically manage the (potentially muliple)
6362 e2fsck processes to print completion bars if it is given a -C option,
6363 with the right thing happening if multiple filesystems are being
6364 checked in parallel.
6366 Mke2fs now has better automatic hueristics to determine the filesystem
6367 parameters to be used for a particular filesystem. Added a new option
6368 -T which allows the user to specify how the filesystem is to be used,
6369 which helps mke2fs do a better job selecting the filesystem parameters.
6371 Mke2fs now creates revision 1 filesystems by default, and with the
6372 sparse superblock feature enabled. The sparse superblock feature is
6373 not understood by Linux 2.0 kernels, so they will only allow read-only
6374 mounts of filesystems with this sparse superblocks.
6376 Fix bug where if /dev/null couldn't be opened (should never happen),
6377 e2fsck would hang in a tight loop.
6379 Make e2fsck handle the case where /lost+found isn't a directory.
6381 E2fsck now uses mallinfo if it exists to get accurate statistics about
6384 Fix bug in e2fsck where it wouldn't check to see if a disconnected
6385 inode had any problems before connecting it to /lost+found.
6387 Add check to e2fsck so it makes sure that total number of inodes in
6388 the filesystem is a sane number.
6390 Fix fencepost error when clearing an the end of the block bitmap which
6391 caused the last block in the bitmap not to get cleared.
6393 Cleaned up a number of messages in e2fsck:
6394 * The message "Group's #'s copy of the group descriptor..."
6395 was fixed so that the correct number would be displayed.
6396 * Added missing space in the "disk write-protected" error messsage
6397 * Cleaned up the error message printed when a non-interactive
6398 e2fsck needs to abort a check because the filesystem
6399 appears to be mounted.
6401 Added a new command-line utility, uuidgen, which will create and print
6404 Make debugfs's icheck command more robust by checking to make sure an
6405 inode has valid blocks before interarting over the inode's blocks.
6407 UUID generation now uses a random-based scheme whenever possible to
6408 prevent potential privacy problems.
6410 Man pages for all of the UUID functions in the lirbary were added.
6412 Fixed bug in fsck so it won't coredump if a filesystem not in
6413 /etc/fstab is given to it.
6415 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6416 that most of the other mount utilities understands.
6418 Mke2fs will make a filesystem even if it appears mounted if the force
6421 Dumpe2fs has new command-line options which allow a filesystem expert
6422 to specify the superblock and blocksize when opening a filesystem.
6423 This is mainly useful when examining the remains of a toasted
6426 The badblocks program has been updated to display correctly on disks
6427 with large block numbers.
6429 The badblocks program no longer gives spurious errors when errors
6430 occur on non-block boundaries, which is common if the blocksize is
6433 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6434 MKE2FS_SYNC environment variable is set. This is to work around a VM
6435 bug in the 2.0 kernel. I've heard a report that a RAID user was able
6436 to trigger it even using a 2.2 kernel, but hopefully it will not be
6437 needed for most Linux 2.2 users.
6439 Fixed miscellaneous documentation and man pages.
6444 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6445 in e2fsck's pass1.c really should have been static.
6447 The return value of the uuid_compare() function was changed to make it
6448 match with the convetions used by strcmp, memcmp, and Paul Leach's
6449 UUID sample document.
6451 The "make depend" process has now been made more automated; it now
6452 automatically word-wraps the dependencies, and only replaces source
6453 Makefile.in if there has been a change in the dependencies. Also, a
6454 top-level "make depend" now recurses through all the subdirectories
6457 The Makefile in .../util has been changed so that subst is built using
6458 the native C compiler during a cross-compilation, since the subst
6459 program is only used during the build process. Also add an explicit
6460 rule to build util/subst by cd'ing to the correct directory and
6463 The man directories are defined in terms mandir, so that the configure
6464 script can override the location of the manual pages.
6466 The config files have been updated to recognize new machine types for
6467 both the i386 and alpha families.
6469 Fsck has been modified so that it will accurately create an
6470 fsck_instance even when the noexecute flag is set. This allows for
6471 accurate debugging of the fsck pass structure. Also, when the verbose
6472 flag is given twice, fsck will print debugging information about when
6473 fsck is waiting for jobs to finish.
6476 E2fsprogs 1.14 (January 9, 1999)
6477 ================================
6479 Fix the fstab parsing code so that it can handle blank lines and
6480 comment characters. Also, missing pass numbers need to be treated as
6483 Fixed a bug in e2fsck where under some circumstances (when e2fsck
6484 needs to restart processing after fixing an egregious inconsistency)
6485 it would try to access already freed memory.
6487 E2fsck now prints non-printable characters in directory entries and
6488 pathnames using '^' and 'M-' notation.
6490 Fixed chattr so that it will ignore symbolic links when doing
6491 recursive descent traversals. For both chattr and lsattr, no longer
6492 print the version string unless the -V option is given.
6494 Allow the system administrator to directly specify the number of
6495 inodes desired in the filesystem, for some special cases where this is
6498 Fix portability problems so that e2fsprogs can be compiled under Linux
6499 1.2 systems and Solaris systems.
6501 Update the config.guess file with a more recent version that will
6502 identify newer Linux platforms.
6507 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6508 an inode number of zero is passed to them.
6510 E2fsprogs 1.13 (December 15, 1998)
6511 ==================================
6513 Fixed a bug in debugfs where an error messages weren't getting printed
6514 when the ext2 library routines to read inodes returned errors in the
6515 stat, cmri and rm commands.
6517 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6518 provided, it won't create an inode table smaller than the minimum
6519 number of inodes required for a proper ext2 filesystem.
6521 Fsck now parses the /etc/fstab file directly (instead of using
6522 getmntent()), so that it can distinguish between a missing pass number
6523 field and pass number field of zero. This caused problems for
6524 diskless workstations where all of the filesystems in /etc/fstab have
6525 an explicit pass number of zero, and fsck could not distinguish this
6526 from a /etc/fstab file with missing pass numbers.
6528 E2fsck will create a /lost+found directory if there isn't one in the
6529 filesystem, since it's safer to create the lost+found directory before
6532 Fixed e2fsck so that it would detect bogus immutable inodes which
6533 happen to be sockets and FIFO files, and offer to clear them.
6535 If a filesystem has multiple reasons why it needs to be checked, and
6536 one of the reasons is that it is uncleanly mounted, e2fsck will print
6537 that as the reason why the filesystem is being checked.
6539 Cleaned up the output routines of mke2fs so that it doesn't overflow
6540 an 80 column display when formating really big filesystems.
6542 Added a sanity check to e2fsck to make sure that file descriptors 0,
6543 1, 2 are open before opening the hard disk. This avoids a problem
6544 where a broken program might exec e2fsck with those file descriptors
6545 closed, which would cause disastrous results if the kernel returns a
6546 file descriptor for the block device which is also used by FILE *
6549 Fixed up the e2fsck progress reporting functions so that the values
6550 reliably reach 100% at the completion of all of the e2fsck passes.
6552 Fixed minor documentation bugs in man pages and usage messages.
6557 Fixed a number of lint warnings in the ext2fs library and potential
6558 portability problems from other OS's header files that might define
6559 CPP macros for names like "max" and "min".
6561 ext2fs_badblocks_list_add() has been made more efficient when it needs
6562 to grow the bad blocks list.
6564 Fixed a bug in e2fsck which caused it to dereference a freed pointer
6565 just before exiting.
6567 Fixed the substition process for generating the mk_cmds and compile_et
6568 scripts so that they will work outside of the build tree.
6570 Add sanity check to e2fsck so that if an internal routine
6571 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6572 and causing a core dump. This should never happen, but...
6574 E2fsprogs 1.12 (July 9, 1998)
6575 ==================================
6577 E2fsprogs now works with glibc (at least with the version shipped wtih
6578 RedHat 5.0). The ext2fs_llseek() function should now work even with
6579 i386 ELF shared libraries and if llseek() is not present. We also
6580 explicitly do a configure test to see if (a) llseek is in libc, and
6581 (b) if llseek is declared in the system header files. (See standard
6582 complaints about libc developers don't understand the concept of
6583 compatibility with previous versions of libc.)
6585 The ext2fs library now writes out the block group number in each of
6586 the superblock copies. This makes it easier to automatically
6587 determine the starting block group of the filesystem when the block
6588 group information is trashed.
6590 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6591 which means that e2fsprogs will ignore the high 8 bits of the
6592 directory entry's name_len field, so that it can be used for other
6595 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6596 E2fsprogs will now support filesystems with 64-bit sized files.
6598 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6600 Added new program "e2label", contributed by Andries Brouwer. E2label
6601 provides an easy-to-use interface to modify the filesystem label.
6603 Fixed bug so that lsattr -v works instead of producing a core dump.
6605 Fixed a minor bug in mke2fs so that all groups with bad superblock
6606 backup blocks are printed (not just the first one).
6608 Mke2fs will check the size of the device, and if the user specifies a
6609 filesystem size larger than the apparent size of the device it will
6610 print a warning message and ask if the user wants to proceed.
6612 E2fsck has a new option -C, which sends completion information to the
6613 specified file descriptor. For the most part, this is intended for
6614 programs to use, although -C 0 will print a spinning character to the
6615 stdout device, which may be useful for users who want to see something
6616 happening while e2fsck goes about its business.
6618 Fixed a bug in e2fsck which could cause a core dump when it needs to
6619 expand the /lost+found directory, and sometimes the bitmaps haven't
6620 been merged in. Also fixed a related bug where ext2fs_write_dir_block
6621 was used to write out a non-directory block. (Which would be bad on a
6622 non-Intel platform with byte swapping going on.)
6624 Fixed bug in e2fsck where it would print a "programming error" message
6625 instead of correctly identifying where a bad block was in used when
6626 the bad block was in a non-primary superblock or block group
6627 descriptor. Also fixed a related bug when sparse superblocks are in
6628 use and there is a bad block where a superblock or block group
6629 descriptor would have been in a group that doesn't include a
6632 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6633 the block group descriptor table is corrupt, it was possible to try to
6634 allocate a huge array, fail, and then abort e2fsck.
6635 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6636 and subsitutes reasonable values if the descriptors are obviously bogus.
6638 If e2fsck finds a device file which has the immutable flag set and the
6639 i_blocks beyond the normal device number are non-zero, e2fsck will
6640 offer to remove it, since it's probably caused by garbage in the inode
6643 When opening a filesystem, e2fsck specially checks for the EROFS error
6644 code, and prints a specific error message to the user which is more
6647 If the filesystem revision is too high, change the e2fsck to print
6648 that this is either because e2fsck is out of date, or because the
6649 superblock is corrupt.
6651 E2fsck now checks for directories that have duplicate '.' and '..'
6652 entries, and fixes this corruption.
6654 E2fsck no longer forces a sync of the filesystem (with attendant sleep
6655 calls) at all times. The ext2fs_flush() function now performs a sync
6656 only if it needed to write data blocks to disk.
6658 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6659 certain errors would not be properly reported.
6661 Updated and expanded a few points in the man pages which users
6662 complained wheren't explicit enough.
6664 Added special case byte-swapping code if compiling on the PowerPC, to
6665 accomodate the strange big-endian variant of the ext2 filesystem that
6666 was previously used on the PowerPC port.
6672 Removed C++ keywords from the ext2fs libraries so that it could be
6675 E2fsck's internal organization has now been massively reorganized so
6676 that pass*.c don't have any printf statements. Instead, all problems
6677 are reported through the fix_problem() abstraction interface. E2fsck
6678 has also been revamped so that it can be called as a library from a
6681 Added new fileio primitives in libext2fs for reading and writing
6682 files on an unmounted ext2 filesystem. This interface is now used by
6685 Added a new libext2fs function for mapping logical block numbers of
6686 a file to a physical block number.
6688 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6689 a block, zeros it, and updates the filesystem accounting records
6692 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6693 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
6695 The libext2fs functions now use a set of memory allocation wrapper
6696 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6697 instead of malloc, free, and resize. This makes it easier for us to
6698 be ported to strange environments where malloc, et. al. aren't
6699 necessarily available.
6701 Change the libext2fs fucntion to return ext2-specific error codes
6702 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6703 and depending on the existence of system error codes (such as EEXIST
6706 Renamed io.h to ext2_io.h to avoid collision with other OS's header
6709 Add protection against ext2_io.h and ext2fs.h being included multiple
6712 The types used for memory lengths, etc. have been made more portable.
6713 In generla, the code has been made 16-bit safe. Added Mark
6714 Habersack's contributed DOS disk i/o routines.
6716 Miscellaneous portability fixes, including not depending on char's
6719 The io_channel structure has a new element, app_data, which is
6720 initialized by the ext2fs routines to contain a copy of the filesystem
6723 ext2fs_check_directory()'s callback function may now return the error
6724 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6725 really do the checking, despite the presence of the callback function.
6728 E2fsprosg 1.11 (June 17, 1997)
6729 ==============================
6731 Fixed e2fsck to detect (previously ignored) conflicts between the
6732 superblock or block group descriptors and block bitmaps, inode
6733 bitmaps, and inode tables.
6735 Fixed bug in e2fsck so that when the message printed out when a block
6736 or inode bitmap conflicts with other data, it has the correct group
6739 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6740 to badblocks. This meant that not all of the filesystem was being
6741 tested for bad blocks!
6743 Fixed an array boundary overrun case which cropped up in
6744 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
6747 Adjusted the number of columns printed by mke2fs when displaying the
6748 superblock backups to avoid running over 80 columns when making a
6749 really big filesystem.
6751 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6752 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6753 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6758 Fixed install rule in lib/ss so that ss_err.h is actually getting
6761 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6762 bassed back to the caller.
6764 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6765 setting the current inode number (which meant this function wasn't
6768 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6769 blocks in the bitmap when increasing the size of the bitmap.
6771 Changed the initial number of blocks allocated by ext2fs_init_dblist()
6772 to be more realistic.
6774 Added a new function ext2fs_allocate_group_table, which sets up the
6775 group descriptor information (and allocates inode and block bitmaps,
6776 and inode tables for a particular group). The function was created by
6777 factoring out code form ext2fs_allocate_tables().
6779 Added a new function ext2fs_move_blocks which takes a bitmap of the
6780 blocks to be moved, and moves them to another location on the
6783 Make the unix_io channel's io_channel_flush implementation calls sync()
6784 to to flush the kernel buffers to disk.
6786 Added a new function ext2fs_dblist_count returns the number of
6787 directory blocks in dblist.
6790 E2fsprogs 1.10 (April 24, 1997)
6791 ===============================
6793 Mke2fs once again defaults to creating revision #0 filesystems, since
6794 people were complaining about breaking compatibility with 1.2 kernels.
6795 Warning messages were added to the mke2fs and tune2fs man pages that
6796 the sparse superblock option isn't supported by most kernels yet (1.2
6797 and 2.0 both don't support parse superblocks.)
6799 Added new flag to mke2fs, -R <raid options>, which allows the user to
6800 tell mke2fs about the RAID configuration of the filesystem. Currently
6801 the only supported raid option is "stride" which specifies the width
6804 Fixed bug in e2fsck where pass1b would bomb out if there were any
6805 blocks marked bad in the inode table.
6807 Fixed rare bug in mke2fs where if the user had a very unlucky number
6808 of blocks in a filesystem (probability less than .002) the resulting
6809 filesystem would be corrupt in the last block group.
6811 Fixed bug where if e2fsck tried to allocate a block to fix a
6812 filesystem corruption problem and the filesystem had no free blocks,
6813 ext2fs_new_block() would loop forever.
6815 The configure script now checks explicitly to see if "-static" works,
6816 since that can't be assumed to be true --- RedHat doesn't install
6817 libc-static by default.
6819 Fixed bug in libext2's block iterator functions where under some
6820 cirmcustances, file with holes would cause the bcount parameter to the
6821 callback function to be incorrect. This bug didn't affect any of
6822 e2fsprogs programs, but it was discovered by Paul Mackerras, the
6823 author of the PPC boot loader.
6825 Removed use of static variables to store the inode cache in libext2fs.
6826 This caused problems if more than one filesystem was accessed via
6827 libext2fs (static variables in libraries are generally a bad idea).
6828 Again, this didn't affect e2fsprogs programs, but it was discovered by
6831 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6832 will compile cleanly with 1.2.13 kernels (even with a.out shared
6838 Added new functions to duplicate an ext2 filesystem handle, and its
6839 associated substructure. New functions: ext2fs_dup_handle(),
6840 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6841 Other structures, such as the io_channel and the inode_cache, now have
6842 a ref count so that they only get freed when they are no longer used
6843 by any filesystem handle. (These functions were added as part of the
6844 development effort for an ext2 resizer).
6846 E2fsprogs 1.09 (April 14, 1997)
6847 ===============================
6849 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6850 accidentally introduced in the 1.08 release. The overhead calculation
6851 was accidentally removed, which caused ext2fs_initialize() to not
6852 notice when the filesystem size needed to be adjusted down because
6853 there wasn't enough space in the last block group.
6855 Fixed bug in version parsing library routine; it was always parsing
6856 the library version string, instead of using the passed-in string.
6858 Clarified chattr man page.
6860 E2fsprogs 1.08 (April 10, 1997)
6861 ===============================
6863 E2fsck 1.07 was very slow when checking very large filesystems with a
6864 lot of files that had hard links (i.e., news spools). This was fixed
6865 by seriously revamping the icount abstraction. Added a formal test
6866 suite for the icount abstraction.
6868 Debugfs now has a "-l" option to the "ls" command, which lists the
6869 inode number, permissions, owner, group, size, and name of the files
6872 Fix a bug in e2fsck where when a directory had its blocks moved to
6873 another location during the pass 1b processing, the directory block
6874 list wasn't updated, so pass 2 wouldn't check (and correct) the
6875 correct directory block.
6877 E2fsck will now treat inodes which contain blocks which are claimed by
6878 the filesystem metadata by treating them as multiply claimed blocks.
6879 This way, the data in those blocks can be copied to a new block during
6880 the pass 1b--1d processing.
6882 E2fsck will attempt to determine the correct superblock number and
6883 display it in the diagnostic and warning messages if possible.
6885 Add support for a new (incompatible) feature, "sparse_super". This
6886 feature reduces the number of blocks which contain copies of backup
6887 superblocks and block group descriptors. (It is only an incompatible
6888 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
6889 support a new -s option; e2fsck will recognize filesystems built with
6890 this feature turned on.
6892 E2fsck now checks the library to make sure is the correct version,
6893 using new library functions. (This helps to diagnose incorrectly
6894 installed e2fsprogs distributions.)
6896 Dumpe2fs now prints more information; its now prints the the
6897 filesystem revision number, the filesystem sparse_super feature (if
6898 present), the block ranges for each block group, and the offset from
6899 the beginning of the block group.
6901 Mke2fs now distributes the inode and block bitmap blok so that the
6902 won't be concentrated in one or two disks in RAID/striping setups.
6903 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6904 choose the largest blocks per group that be chosen. (For 2k blocks,
6905 you can have up to 16384 blocks/group; for 4k blocks, you can have up
6906 to 32768 blocks/group.) Previously mke2fs would not allow
6907 specification of more than 8192 blocks per group, even if you were
6908 using a 2k or 4k block group.
6913 Added a new function ext2fs_create_icount2() which takes a "hint"
6914 argument. This hint argument presets the icount array with the list
6915 of inodes which actually need to be in the icount array. This really
6916 helps to speed up e2fsck.
6918 Added a new function ext2fs_icount_validate() which checks the rep
6919 invariant for the icount structure. This is used mostly for testing.
6921 The error mesasage given when a bad inode number is passed to
6922 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6923 EXT2FS_UNMARK_ERROR).
6925 Added a new function ext2fs_set_dir_block which sets the block of a
6926 dblist entry, given the directory inode and blockcnt.
6928 Added a new function ext2fs_get_library_version() which returns the
6929 current library version, and ext2fs_parse_version_string() which
6930 returns a version number based on a e2fsprogs version string.
6932 The icount functions will return EINVAL if the passed in inode number
6935 E2fsprogs 1.07 (March 9, 1997)
6936 ==============================
6938 E2fsck is now uses much less memory when checking really large
6939 filesystems (or rather, filesystems with a large number of inodes).
6940 Previously a filesystem with 1 million inodes required 4 megabytes of
6941 memory to store inode count statistics; that storage requirement has
6942 now been reduced to roughly half a megabyte.
6944 E2fsck can now properly deal with bad blocks appearing inside the
6945 inode table. Instead of trying to relocate the inode table (which
6946 often failed because there wasn't enough space), the inodes in the bad
6947 block are marked as in use.
6949 E2fsck will automatically try to use the backup superblocks if the
6950 primary superblocks have a bad magic number or have missing meta-data
6951 blocks (or meta-data blocks which are out of range).
6953 E2fsck's pass 3 has been made more efficient; most noticeable on
6954 filesystems with a very large number of directories.
6956 Completely revamped e2fsck's system of printing problem reports. It
6957 is now table driven, to make them more easily customizeable and
6958 extendable. Error messages which can be printed out during preen mode
6959 are now one line long.
6961 Fixed e2fsck's filesystem swapping code so that it won't try to swap
6962 fast symbolic links or deleted files.
6964 Fixed e2fsck core dumping when fixing a filesystem which has no
6965 directories (not even a root directory).
6967 Added a check to e2fsck to make sure that the length of every
6968 directory entry is a multiple of 4 (since the kernel complains if it
6971 Added a check to e2fsck to make sure that a directory entry isn't a
6972 link to the root directory, since that isn't allowed.
6974 Added a check to e2fsk to now make sure the '.' and '..' directory
6975 entries are null terminated, since the 2.0 kernel requires it.
6977 Added check to write_bitmaps() to make sure the superblock doesn't get
6978 trashed if the inode or block bitmap is marked as being block zero.
6980 Added checking of the new feature set fields in the superblock, to
6981 avoid dealing with new filesystem features that this package wasn't
6984 Fixed a fencepost error in ext2fs_new_block() which would occasionally
6985 try to allocate a block beyond the end of a filesystem.
6987 When the UUID library picks a random IEEE 802 address (because it
6988 can't find one from a network card), it sets the multicast bit, to
6989 avoid conflicting with a legitimate IEEE 802 address.
6991 Mke2fs now sets the root directory's owner to be the real uid of the
6992 user running mke2fs. If the real uid is non-zero, it also sets
6993 the group ownership of the root directory to be the real group-id of
6994 the user running mke2fs.
6996 Mke2fs now has more intelligent error checking when it is given a
6997 non-existent device.
6999 When badblocks is given the -vv option, it now updates the block that
7000 it is currently testing on every block.
7002 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
7003 currently correctly if PATH wasn't already set.
7005 Shared libraries now built with dependencies. This allows the shared
7006 library files to be used with dlopen(); it also makes the transition
7007 to libc 6 easier, since ld.so can tell which libc a particular shared
7008 library expects to use.
7013 Added new abstraction (defined in dblist.c) for maintaining a list of
7014 blocks which belongs to directories. This is used in e2fsck and other
7015 programs which need to iterate over all directories.
7017 Added new functions which test to see if a contiguous range of blocks
7018 (or inodes) are available. (ext2fs_*_bitmap_range).
7020 Added new function (ext2_inode_has_valid_blocks) which returns true if
7021 an inode has valid blocks. (moved from e2fsck code).
7023 Added new function (ext2fs_allocate_tables) which allocates the
7024 meta-data blocks as part of initializing a filesystem. (moved from
7027 Added a new I/O manager for testing purposes. It will either allow a
7028 program to intercept I/O requests, or print debugging messages to
7029 trace the activity of a program using the I/O manager.
7031 The badblocks_list functions now store the bad blocks in a sorted
7032 order, and use a binary search to speed up badblocks_list_test.
7034 The inode scan function ext2fs_get_next_inode() may now return a soft
7035 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
7036 those cases where part of an inode table is missing or there is a bad
7037 block in the inode table.
7039 Added a new function (ext2fs_block_iterate2) which adds new arguments to
7040 the callback function to return a pointer (block and offset) to the
7041 reference of the block.
7043 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
7044 application to jump to a particular block group while doing an inode
7047 The badblocks list functions were renamed from badblocks_* to
7048 ext2fs_badblocks_*. Backwards compatibility functions are available
7049 for now, but programs should be modified to use the new interface.
7051 Some of the library functions were reorganized into separate files to
7052 reduce the size of some programs which statically link against the
7055 Put in some miscellaneous fixes for the Alpha platform.
7058 E2fsprogs 1.06 (October 7, 1996)
7059 ================================
7061 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
7062 smash the backup copies in ext2fs_close(). (The problem was that when
7063 e2fsck -p discovered the problem, while it was closing the filesystem
7064 and exiting, it was also blowing away the backup superblocks on the
7065 disk, which was less than friendly.) We now make it the case that we
7066 only write out the backup superblock and the back block descriptors if
7067 the filesystem is completely free from problems.
7069 Fixed a bug in block_interate in the lib/ext2fs library which caused
7070 e2fsck to fail on GNU Hurd-created filesystems.
7072 Add support for Linux/FT's bootloader, which actually uses
7073 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
7076 Add support for the "A" (no atime update) attribute. (Note: this
7077 attribute is not yet in production kernels.)
7079 The test suite is not automatically run when doing a "make all" from
7080 the top level directory. Users should manually run "make check" if
7081 they wish to run the test suite.
7083 Upon a preenhalt(), make the printed message more explicit that
7084 running e2fsck "MANAULLY" means without the -p or -a options.
7086 In e2fsck, if a disconnected inode is zero-length, offer to clear it
7087 instead of offering to connect it to lost+found.
7089 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
7090 e2fsck to be run over it, change e2fsck to explicitly display this
7093 For dumpe2fs and e2fsck, cause the -V option to print out which
7094 version of the ext2fs library is actually getting used. (This will
7095 help detect mismatches of using a 1.06 utility with a 1.05 library,
7101 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
7102 the naming convention.
7104 In ext2fs_initialize(), make sure the description for the inode bitmap
7105 is correctly initialize.
7107 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
7109 E2fsprogs 1.05 (September 7, 1996)
7110 ==================================
7112 Add support for new fields in the ext2 superblock --- volume name,
7113 volume UUID, and last mounted field. Dumpe2fs displays these fields,
7114 tune2fs and mke2fs allows you to set them. E2fsck will automatically
7115 generate a UUID for those volumes that don't have them.
7117 Put in support for e2fsck to recognize HURD specific ext2 features ---
7118 most notably, the translator block. The e2fsprogs tools will now use
7119 the creator_os field in the superblock to correctly handle different
7120 OS-specific variants of the ext2 filesystem.
7122 E2fsck now fixes inodes which have a the deletion time set, but which
7123 have a non-zero i_link_count field by offering to clear the deletion
7124 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
7125 ext2 kernel behavior) and offered to unlink the file.
7127 If e2fsck sets the clean bit, but nothing else, set the exit code
7128 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
7129 set the filesystem valid bit when it was previously cleared. :-) This
7130 was needed to make the HURD fsck driver happy.
7132 If the user refuses to attach an unattached inode, e2fsck will no
7133 longer set the inode's link count. Otherwise, the inode would end up
7134 getting marked as unused, which might cause loss of data later.
7136 Make the message issued by e2fsck when the superblock is corrupt less
7137 confusing for users. It now mentions that another reason for the
7138 "corrupt superblock" message might be that the partition might not be
7139 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
7141 Make the libext2 library more robuest so that e2fsck won't coredump on
7142 an illegal superblock where the blocksize is zero. (f_crashdisk is
7145 By default, create filesystems where the default checkinterval is 6
7146 months (180 days). Linux servers can be robust enough that 20 reboots
7147 can be a long, long time.
7149 Added configure flag --enable-old-bitops, which forces the bitops to
7150 use the old (native) bitmask operations. By default on the sparc
7151 platform, the standard ext2 bit ordering is now used.
7153 Added a new feature to e2fsck to byte-swap filesystems; this can be
7154 used to convert old m68k filesystems to use the standard byte-order
7155 storage for the superblock, inodes, and directory blocks. This
7156 function is invoked by using the '-s' option to e2fsck.
7158 Debugfs's "dump" command has been enhanced so that it writes out the
7159 exact size of the file so that the nulls at the end of the file are
7160 eliminated. The command also accept a new "-p" option which will
7161 attempt preserve to preserve the ownernship, permissions, and
7162 file modification/access times.
7164 Debugfs has two new options, -f and -R. The -R option allows the user
7165 to execute a single debugfs command from the command line. The -f
7166 option allows the user to specify a "command file" containing debugfs
7167 commands which will get executed.
7169 Dumpe2fs now pretty prints the check interval, instead of just
7170 printing the check interval as a number of seconds.
7172 Fix bugs in debugfs: the params command when no filesystem is opened
7173 no longer causes a core dump. It is now possible to unlink a file
7174 when a pathame containing a '/' is specified.
7176 Tune2fs has a new -C option which sets the number of times the
7177 filesystem has been mounted.
7179 Fix the chattr '-v' option so that it actually works. Chattr was
7180 being buggy about the -v option parsing.
7185 The directory lib/uuid contains a set of library routines to generate
7186 DCE compatible UUIDs.
7188 Extended ext2fs_namei() to handle symbolic links. Added new function
7189 ext2fs_nami_follow() which will follow last symbolic link in the case
7190 where the pathname points to a sym link.
7192 The ext2fs_block_iterate function will now return the HURD translator
7193 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
7194 iterator to return data blocks only. The ext2fs.h file now defines
7195 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
7196 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
7197 count field of the iterator callback function.
7199 The test script driver now takes an optional second argument, which is
7200 the test case to be run. This allows you to run a test case without
7201 needing to run the entire test suite.
7203 On Linux ELF systems, install the .so files in the correct places
7204 (/usr/lib). The .so files must be stored in the same directory as the
7207 Fixed miscellaneous HURD compilation issues with header file being
7208 included in the right order.
7210 Fixed debugfs so that it resets optind to zero, not one, since setting
7211 optind to zero is more correct.
7214 E2fsprogs 1.04 (May 16, 1996)
7215 =============================
7217 First "official" (1.03 was a limited release only) to support building
7218 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
7221 This package includes a RPM specs file, that it can be built using the
7222 RedHat Package Manager.
7224 E2fsck now prints a hint that if there are lots of incorrectly located
7225 inode bitmaps, block bitmaps, and inode table blocks, the user might
7226 want to try using e2fsck -b 8193 first, to see if that fares any
7229 For ext2 filesystem written with the hurd, debugfs will now print out
7230 the translator field when printing an inode structure.
7232 Lots of miscellaneous linking/installation cleanups:
7234 Libraries are now linked using a relative pathname, instead of
7235 relying on -L working correct. It doesn't, in many cases, including
7236 current versions of GNU ld. This guarantees that the build tree is
7237 linking with the right libraries, instead of the ones installed in
7240 Header files, man pages, and the et/ss shell scripts are now
7241 generated using a custom substitution script, instead of relying on
7242 the configure script. This prevents needless recompilation of
7243 files; in addition, the custom substitution script is much faster.
7245 e2fsck may now be linked dynamically, by using the
7246 --enable-dynamic-e2fsck flag to configure. This is not recommended,
7247 since it increases e2fsck's dependence on other files, but some
7248 people need to save disk space, and other critical programs on their
7249 systems were being linked dynamically anyway.
7251 Programs such as fsck which didn't need to be linked against
7252 libext2fs (or mke2fs which didn't need to be linked against libe2p)
7253 only link against libraries they actually need. Otherwise, those
7254 programs would require the presense of libraries that otherwise
7255 could be removed from a rescuse diskette.
7257 The ss include files are now installed correctly so they can
7258 actually be used by another package.
7260 If the profiling libraries are built, they are now installed on a
7261 "make install-libs".
7264 E2fsprogs 1.03 (March 27, 1996)
7265 ===============================
7267 Change the m68k bit numbering for bitmasks to match the bit numbering
7268 used by all other ext2 implementations. (This change was requested by
7269 the m68k kernel development team.)
7271 Support (in-development) filesystem format revision which supports
7272 (among other things) dynamically sized inodes.
7274 Fixed a bug in the ext2 library so that an intelligent error is
7275 returned if mke2fs is run with a ridiculously small number of blocks
7278 Fixed a bug in the ext2 library which required that the device be
7279 openable in read/write mode in order to determine its size. This
7280 caused e2fsck -n to require read/write access when it was not
7281 previously necessary.
7283 Fixed a bug in e2fsck which casued it to occasionally fail the test
7284 suite depending on which version of the floating point library it was
7287 Fixed a bug in e2fsck so that it now halts with a fatal error when
7288 certain superblock consistency checks fail. Previously it continued
7289 running e2fsck, with some potential confusing/damaging consequences.
7291 Added new flag to fsck which allows the root to be checked in parallel
7292 with other filesytems. This is not the safest thing in the world to
7293 do, but some system administrators really wanted it.
7295 Fixed -Wall flames in lib/ss.
7298 E2fsprogs 1.02 (January 16, 1996)
7299 =================================
7301 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
7303 Change e2fsck to print statistics of how many non-contiguous files are
7304 on the system. Note that a file which is larger than 8k blocks, it is
7305 guaranteed to be non-contiguous.
7307 In mke2fs, print a warning message if a user tries to format a whole
7308 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
7309 whole disk, the -F (force) option forces mke2fs to format a whole disk
7312 Fix a bug in fsck where in some cases it might start checking
7313 partitions in the next pass before it finishes checking partitions in
7314 the current pass. This still won't cause two partitions on the same
7315 disk will be checked, so it's rarely a problem in real life.
7317 Patch lsattr so that it won't hang when checking a named pipe.
7319 Minor compilation fixes:
7320 * Fix the order of libraries that were linked in debugfs.
7321 * Allow the sources to be compiled with -ansi turned on.
