1 E2fsprogs 1.42.9 (December 28, 2013)
2 ====================================
4 Mke2fs will detect an attempt to create a file system on a loop
5 mounted file and complain without the -FF option. Also fixed mke2fs
6 so it allows the creation of a file system on a mounted device with
7 two -F options, as documented in the man page, instead of three -F
10 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
11 libext2fs to correctly handle bigalloc and 64-bit file systems. There
12 were many corner cases that had not been noticed in previous uses of
13 these file systems, since they are not as common. Some of the bugs
14 could cause file system corruption or data loss, so users of 64-bit or
15 bigalloc file systems are strongly urged to upgrade to e2fsprogs
18 The tune2fs program will now not allow changing the uuid on a mounted
19 file system which has the uninit_bg feature enabled. This avoids a
20 nasty race where the kernel and tune2fs are both retrying rewrite the
21 group descriptors at the same time, with different ideas about what
24 When e2fsck is rehashing an extent-mapped directory, it's possible
25 (although very rare) that an extent block will need to be allocated;
26 fix e2fsck to make sure that the block gets marked as used.
28 Mke2fs will now properly set the LARGE_FILE feature when creating a
29 journal >= 2GB --- which can happen when using 64k block size.
31 Fixed debugfs so that its freei command will correctly handle a request
32 to free a range of consecutive inodes.
34 Fixed 2fsck so it will not erroneously complain that an external journal
35 is invalid if it is exactly 2**32 blocks.
37 Fixed e2fsck so it won't try checking for, and adding, a missing
38 lost+found directory when running in read-only mode.
40 Fixed e2image to avoid some buffer overruns which would cause it to when
41 creating a "standard (non-raw, non-qcow2) image file. Standard
42 e2image files are actually very rarely used, so we didn't notice when
43 the changes to enable the qcow2 format broke this e2image mode.
45 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
46 on the resize_inode feature when the meta_bg feature is set, since
47 these two features can not be set at the same time.
49 Fixed tune2fs so that when it disables the quota feature, it updates all
50 of the backup superblocks.
52 Fixed dumpe2fs that would cause it to abort when run using an image file
53 when trying to print the journal information (which is not present in
54 an e2image created image file).
56 Fixed a potential integer overflow in e2reefrag.
57 (Addresses-Debian-Bug: #718205)
59 Enhance debugfs so that when copying a sparse file from a native file
60 system into the file system image using the "write" command, it will
61 create a sparse file into the destination file system.
63 Enhanced debugfs so it can support a command line which is up to 8k
66 E2image will refuse (unless the -f option is specified to force the
67 issue) to create a raw or qcow image using a mounted file system,
68 unless the -f option is specified to force the issue.
70 E2image has been optimized for using it to efficiently copy a file
71 system by only copying the allocated blocks, by using the options -ra.
72 New options (-o and -O) have been added so that a source and
73 destination offset can be given. The -p option will print progress
74 information so the user will know how far along the copy is going.
75 And finally, the new option -c is useful for updating a file system on
76 an SSD, by avoiding unnecessary writes. E2image can also shift a file
77 system image by doing an in place move.
79 Fix a regression introduced in 1.42.8 which would cause e2fsck to
80 erroneously report uninitialized extents past the EOF (as determined by
81 i_size) to be invalid.
83 Fixed resize2fs so under a corner case when an inode has a complex
84 extent tree, it will not corrupt an interior node in the extent tree.
86 Fixed resize2fs which would sometimes corrupt a file system when
87 shrinking a file system to a minimum size using resize2fs -M.
88 (Addresses Debian Bug: #660793)
90 Fixed resize2fs so that it will relocate inode table blocks if this
91 becomes necessary when shrinking the file system.
93 Fixed resize2fs and e2fsck so they will not crash when hit a failure
94 while operating on a file system with the MMP feature enabled.
96 Fixed a bug in debugfs which caused it create an invalid inode when
97 trying to write a zero-length file.
99 E2fsck will no longer crash if it tries to delete an invalid
100 extent-mapped symlink.
102 E2fsck will no longer crash if it comes across an directory which is
103 larger than 2GB (which is not allowed in valid file systems).
105 Fixed debugfs's help texts to fully document all options and otherwise
108 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
111 Fixed various Debian Packaging Issues (#698879, #721365)
117 Fix sparse, gcc -Wall and clang nits.
119 Update config.{guess,sub} to the latest version
121 Fixed various memory and file descriptor leaks on various error paths,
122 as well as some missing error return checks, which were found using
125 Run sparse against source files when building e2fsprogs with 'make
126 C=1'. If instead C=2, it configures basic ext2 types for bitwise
127 checking with sparse, which can help find the (many many) spots where
128 conversion errors are (possibly) happening.
130 Allow the regression test to be run in chrooted environments where
131 /etc/mtab might be missing.
133 The ext2fs_punch() function, which was introduced in 1.42, was broken
134 in many ways, but this was never noticed since it wasn't used for
135 anything significant. Some of the bugs include failing when trying to
136 punch a completely sparse file, failing when punching an extent-mapped
137 inode when the starting block was at the beginning of the inode, and
138 not being able to punch a single block (where start_blk == end_block).
139 It also didn't handle being passed an invalid, too-large ending block
140 number, and didn't handle properly terminate at the right place when
141 operating on an indirect-mapped inode.
143 Fixed some minor typo's in the error catalog for libext2fs.
145 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
146 setting the file size, to zero the rest of the block to the end of the
147 file, so that if an ext4 FUSE driver tries to extended the file, that
148 we don't avoid stale data from being returned.
150 Fixed ext2fs_bmap() to disallow clients from trying to map or set
151 logical blocks which are larger than what an extent-mapped or indirect
152 block-mapped inode can allow.
154 If debugfs (or some userspace program using libext2fs) creates a file
155 which is larger than 2GB, make sure the large_file feature flag gets
158 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
159 directory which are large enough, the directory entry could get
160 inserted more than once in the directory.
162 If quota support is disabled (which is the default), make sure that
163 all traces of the quota support is removed from usage messages, man
164 pages, and tune2fs must not be able to enable the quota file system
165 feature. (Addresses Red Hat Bugzilla: #1010709)
167 The ext2fs_file_write() now updates i_size on a successful write,
168 instead of only updating i_size wen the file is closed via
171 Added a shell script, populate-extfs.sh which uses debugfs to populate
172 an ext2/3/4 file system image from a given directory. It is similar
173 to the genext2fs program, but it supports ext3 and ext4 file system.
175 Add changes to the libext2fs library to support block group
176 descriptors larger than 64 bytes (for future compatibility).
178 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
179 leave an extra block in the file when truncating the file down to
182 The html version info pages are now built using makeinfo --html
183 instead of the unmaintained and now-obsolete texi2html program.
186 E2fsprogs 1.42.8 (June 20, 2013)
187 ================================
189 As a part of mke2fs's option parsing cleanup, the use of the -R option
190 will give a warning that it is depreated (it has been so documented
191 since 2005) and -E should be used instead.
193 Mke2fs will not give warnings about the bigalloc and quota options in
196 If an invalid journal size is given to mke2fs, it will now complain
199 Debugfs was erroneously giving spurious error messages for certain
200 extent_inode subcommands which take arguments (split_node,
201 replace_node, and insert_node). This has been fixed.
203 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
204 other programs is used by mke2fs.
206 Change mke2fs so that it does not set the root directory to the real
207 uid/gid of the mke2fs process. Add the extended option root_owner to
208 override this behavior.
210 Fix resize2fs when shrinking file systems to make sure that bitmap
211 blocks aren't left outside the bounds of the shrunken file system.
212 This could happen with flex_bg file systems that were grown using
213 the old online resizing algorithm.
215 E2fsck will now detect and repair corrupted extent trees which contain
216 invalid extents at the end of the extent tree leaf block.
218 E2fsck will now longer complain about zero length extended attribute
221 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
224 Add safety check so tune2fs will not attempt to set the inode size to
225 be larger than the block size.
227 Fix e2fsck so it can check a read-only root file system with an
228 external journal. (Addresses Debian Bug: #707030
230 Fix off-line resizing of file systems with flex_bg && !resize_inode
231 (Addresses Debian Bug: #696746)
233 Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
236 Enhance chattr to allow clearing the extent flag if the kernel allows
237 migrating extent based files to use indirect blocks.
239 Update German translation.
241 Updated/fixed various man pages. (Addresses Debian Bugs: #712429,
244 Fixed various Debian Packaging Issues (Addresses Debian Bug #708307)
249 Use secure_getenv() in preference to __secure_getenv().
251 Optimize CPU utilization of ext2fs_bg_has_super().
253 Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
254 SEEK_CUR is used with large files.
256 The ext2fs_read_inode_full() function will no longer use
257 fs->read_inode() if the caller has requested more than the base 128
258 byte inode structure and the inode size is greater than 128 bytes.
260 Fix build failure with --enable-jbd-debug.
262 Clean up filtering of outputs for the regression tests by using a
265 Fix gcc -Wall and clang nits.
268 E2fsprogs 1.42.7 (January 21, 2013)
269 ===================================
271 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
272 quota features are still under development. For more information
274 * https://ext4.wiki.kernel.org/index.php/Bigalloc
275 * https://ext4.wiki.kernel.org/index.php/Quota
277 Add some new options to filefrag from Lustre's patches to e2fsprogs:
278 * add -k option to print extents in kB-sized units (like df -k)
279 * add -b {blocksize} to print extents in blocksize units
280 * add -e option to print extent format, even when FIBMAP is used
281 * add -X option to print extents in hexadecimal format
283 Fix resize2fs so that it can handle off-line resizes of file systems
284 with the flex_bg feature but without a resize_inode (or if we run out
285 of reserved gdt blocks). This also fixes a problem where if the user
286 creates a filesystem with a restricted number of reserved gdt blocks,
287 an off-line resize which grows the file system could potentially
288 result in file system corruption.
290 Fix a resize2fs bug which could cause it to corrupt bigalloc file
291 systems when doing an off-line resize.
293 Further optimize resize2fs so it doesn't use quite as much CPU when
294 resizing very large file systems.
296 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
297 possibly corrupt the file system while resizing 64-bit file systems.
299 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
300 mke2fs crash due to a divide-by-zero if the 64bit file system feature
303 Add better error checking to mke2fs to check for invalid parameters
304 when creating bigalloc file system.
306 When creating bigalloc filesystems, the -g option to mke2fs will now
307 specify the number of clusters per block group.
309 Add to debugfs the functionality to corrupt a specific file system
310 block via the "zap_block" command.
312 Add to debugfs the functionality to print out a hex dump of a block in
313 the file system via the "block_dump" command.
315 Add to debugfs the functionality to manipulate the extent tree
316 directly via the "extent_open" command.
318 Fixed debugfs's mknod command so that it updates the block group
321 Fix e2fsck so it can detect and fix inconsistencies in the interior
322 nodes of an inode's extent tree.
324 Fix a potential memory corruption failure in e2fsck's error path if
325 the call to ext2fs_open2() fails.
327 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
328 resulting file name for the log file is longer than 100 bytes, that it
329 properly handles this situation instead of crashing.
331 E2fsck will now report the amount of memory that it attempted to
332 allocate when a memory allocation request fails, to make it easier to
333 track down the problem.
335 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
338 E2image can now include all data blocks in the e2image output file
339 when the user specifies the -a option.
341 If e2fsprogs is compiled without --enable-quota, make sure that
342 tune2fs can not turn on the feature for new-style quota support, since
343 afterwards, none of the e2fsprogs tools will be willing to touch that
346 Optimize e2fsck's so that it uses much less CPU for large file
347 systems. This can result in significant speedups, especially on
348 CPU-constrained systems. This was primarily done by optimizing
349 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
351 Fix debugfs's htree command so that all its messages are sent through
354 Fixed debugfs's "dump_file" and "cat" functions work correctly
355 on file systems whose block size is greater than 8k.
357 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
358 less memory. (Addresses Google Bug: 7269948)
360 Update the spd_readdir.c file in the contrib directory to include some
361 additions which were made in 2008 that didn't get folded into the
362 version which we checked into the e2fsprogs source tree. These
363 enhancements include thread safety, support for readdir64_r(), and
364 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
366 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
369 Add a command to debugfs to create symlinks.
371 Document the bigalloc feature in the mke2fs man page. (Addresses
380 Fix a spelling typo in the libext2fs texinfo documentation.
382 Change the output from "make check" so that tools such as emacs's "M-x
383 compile" does not mistake the output as containing a compiler error.
385 Export two new functions from libext2fs: ext2fs_extent_node_split()
386 and ext2fs_extent_goto2().
388 The ext2fs_extents_fix_parents() was fixed so it does not modify the
389 location of the extent handle if its current location is at an
390 interior node, rather than a leaf node of an inode's extent tree.
392 Add a regression test to assure that e2fsck can correctly fix an
393 inconsistent interior node in an inode's extent tree.
395 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
396 correctly support bigalloc file systems which use store block usage
397 information in units of clusters.
399 Fixed the help text in the configure script for --enable-quota.
401 The m68k-specific bitops code has been removed since they were
402 incorrectly treating bit numbers with the high bit set as signed
403 integers. Furthermore, modern compilers do a good enough job
404 optimizing the generic code there is no point in having the m68k
405 specific asm statements.
407 Fixed how we link the test programs so they always use the static
408 libraries, so that we test using the libraries which we have just
411 Update config.guess and config.sub to the latest versions from the GNU
414 Fixed the com_err.texinfo file so that it can produce a valid
415 postscript/pdf printed output.
417 Add a regression test which checks debugfs's ability to create
418 symlinks, named FIFO's, and device nodes.
420 Add a function ext2fs_symlink(), which creates symlinks to the
423 Add debugging code so we can test old kernel interfaces for online
424 resize to resize2fs. This backwards compatibility checking is keyed
425 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
426 test the functionality of the kernel's older resize ioctls without
427 needing to install an old version of resize2fs, and to also test a
428 modern resize2fs's ability to work with older kernels without having
429 to install an older version of the kernel.
432 E2fsprogs 1.42.6 (September 21, 2012)
433 =====================================
435 When mke2fs creates file systems with lazy itable initialization, the
436 progress updates for writing the inode table happens so quickly that
437 on a serial console, the time to write the progress updates can be the
438 bottleneck. So mke2fs will now only update its progress indicators
441 Resize2fs will skip initializing the inode tables if the kernel
442 supports lazy_itable_init, which speeds up growing off-line growth of
443 uninit_bg file systems significantly. Resize2fs will now also
444 correctly set the itable_unused field in the block group descriptor to
445 speed up the first e2fsck after the file system is grown.
447 Resize2fs has been fixed so that on-line resizing of meta_bg file
448 systems work correctly. This is needed to grow file system which are
451 Resize2fs will now correctly handle resizing file systems to 16TB on
452 32-bit file systems when "16TB" is specified on the command line.
454 Fix mke2fs so that it will be careful to set the reserved blocks ratio
455 larger than 50%; this can happen when creating small file systems and
456 when the last block group is dropped because there are not enough
457 blocks to support the metadata blocks in the last block group.
459 Fixed spelling mistake in debugfs's help message.
461 Fixed a potential seg fault in e2fsck when there is an I/O error while
462 reading the superblock.
464 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
466 Updated/fixed various man pages. (Addresses Sourceforge Bug:
472 The configure option --enable-relative-symlink was broken so that it
473 needed to be --enable-symlink-relative-symlinks. We will support both
474 for at least two years, but then the worng configure option will be
477 Fixed a regression introduced in 1.42.5 so the link order for
478 e2fsprogs' libraries will be correct for both static and shared
479 linking. (Addresses Sourceforge Bug: #3554345)
481 Add support for e2fsprogs to be compiled using clang/LLVM.
483 Fix portability problems on non-Linux systems: avoid compile failures
484 on systems that don't have malloc.h
486 Fix f_mmp regression test suite so that debugfs gets killed if the
491 E2fsprogs 1.42.5 (July 29, 2012)
492 ================================
494 Fixed a bug with mke2fs where if there is only 8 inodes per block
495 group, the calculation of the number of uninitialized inodes in the
496 first block group would go negative. This resulted in "mke2fs -N 256
497 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
498 would run out of space. (Addresses Sourceforge Bug: #3528892)
500 Fixed a bug in how e2fsck would uniquify directory entry names.
501 (AddressesSourceforge Bug: #3540545)
503 Previously, e2fsck would only allow a mounted file system to be
504 checked if it was the root file system and it was mounted read-only.
505 Now it will allow any file system mounted read-only to be checked if
506 the -f option is specified. This makes it easier to test how e2fsck
507 handles checking file systems which are mounted without having to test
508 on the root file system.
510 Fixed a problem if e2fsck where if the root file system is mounted
511 read-only, e2fsck would not clear an error indication in the journal
512 superblock. Combined with a kernel bug, this would cause the e2fsck
513 to check the file system after every single boot.
515 The e4defrag program can now handle device symlinks, such as
516 /dev/mapper/testvg-testlv, instead of insisting on a less
517 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
520 Fixed filefrag so it will not crash with a segfault on files from a
521 virtual file system such as /proc. (e.g., "filefrag
524 Fixed filefrag so that it correctly reports the number of extents.
525 (Addresses Red Hat Bugzilla: #840848)
527 Fixed a file descriptor leak in logsave which could cause it to hang.
528 (Addresses Debian Bug: #682592)
530 Fixed e2fsck so that the file system is marked as containing an error
531 if the user chooses not to fix the quota usage information.
533 Fixed tune2fs so that it correctly removes the quota feature when the
534 last quota inode is removed.
536 Fix tune2fs so that after removing a quota inode, the block bitmap is
537 updated; otherwise, e2fsck would complain after running 'tune2fs -O
540 Fix tune2fs so that when converting a file system from using legacy
541 quota files to the new quota file system feature with hidden quota
542 files, the accounting for these files is handled correctly so that
543 e2fsck doesn't complain.
545 Improved e2fsck's verbose reporting statistics, and allow the more
546 verbose reporting to be enabled via /etc/e2fsck.conf.
548 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
550 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
556 Fixed portability problems on other operating systems (e.g., Hurd and
557 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
559 Make sure that shared libraries link with the shared libraries built
560 in the build tree, instead of the system provided libraries.
561 Previously, libraries and executables were linked with the system
562 libraries if present, and possibly using static archives instead of
563 shared libraries. This was also problematic since if libext2fs.so is
564 linked with a static libcom_err.a from system, the build system would
565 attempt to link without -lpthread. (Addresses Sourceforge Bug:
569 E2fsprogs 1.42.4 (June 12, 2012)
570 ================================
572 Fixed more 64-bit block number bugs (which could end up corrupting
573 file systems!) in e2fsck, debugfs, and libext2fs.
575 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
576 not properly propagating the journal's s_errno field to the superblock
577 field; it was not checking this field if the journal had already been
578 replayed, and if the journal *was* being replayed, the "error bit"
579 wasn't getting flushed out to disk.
581 Fixed a false positive complaint by e2fsck if all of the extents in
582 the last extent tree block are uninitalized and located after the end
583 of the file as defined by i_size.
585 The dumpe2fs will now display the journal's s_errno field if it is
586 non-zero, and it will also display the journal's 64-bit feature flag
589 Fix e2fsck so that it always opens the device file in exclusive mode
590 when it might need to modify the file system, and never if the -n
591 option is specified. (Previously, there were a few corner cases where
592 it might get things wrong in either direction.)
594 E2fsck now correctly truncates or deallocates extent-mapped inodes on
595 the orphan list. The root cause was a bug in libext2fs's block
596 iterator which could end up skipping an extent when the last block in
597 an extent is removed, causing the current extent to be removed from
600 E2fsck now correctly sets the global free block and inode counts when
601 truncating or removing inodes on the orphan list in preen mode.
602 Previously, it would leave these values would be set incorrectly,
603 which is largely a cosmetic issue since the kernel no longer pays
604 attention to those fields, but it can cause spurious complaints in
605 subsequent e2fsck runs.
607 Fix i_blocks accounting when the libext2fs library needs to add or
608 remove an extent tree block on bigalloc file systems.
610 The lsattr and chattr programs now support the No_COW flag for the
613 Debugfs now interprets date strings of the form @ddd as ddd seconds
614 after the beginning of the epoch. This is handy when setting an inode
615 number into the d_time field when debugging orphan list handling.
617 Fix a precedence bug with built-in quota support which might result in
618 e2fsck paying attention to the quota inode field even if the built-in
619 quota feature flag is not set. Fortunately, in practice that
620 superblock field should be zero for non-built-in quota file systems,
621 so it's unlikely this bug would have caused problems.
623 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
629 The regression test suite can now run the integration tests in the
630 tests directory in parallel, via "make -jN check".
632 Add new test, f_zero_extent_length which tests e2fsck's handling of
633 the case where all of the extents in the last extent tree block are
634 uninitialized extents after i_size.
636 Add a new test, f_jnl_errno, which checks handling of an error
637 indication set in the journal superblock.
639 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
642 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
643 tests e2fsck's handling of orphan inodes in preen mode, and truncation
644 of extent inodes on the orphan list.
646 Fixed more OS X portability issues.
649 E2fsprogs 1.42.3 (May 14, 2012)
650 ===============================
652 Fix a bug in the Unix I/O manager which could cause corruption of file
653 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
654 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
655 dumpe2fs to incorrectly display block numbers > 32-bits.
657 Improve the support for integrated quota files (where quota is a first
658 class supported feature using hidden files in the ext4 file system).
659 Previously the quota file was getting rewritten even when it was not
660 necessary, and e2fsck would erroneously try to hide quota files which
663 Quiet complaints in e2fsck when the total free blocks or inodes are
664 incorrect in the superblock after an system crash, since we don't
665 update nor depend on the superblock summaries at each commit boundary.
667 Fixed a regression introduced in 1.42.2 which would cause applications
668 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
669 would were still using the legacy 32-bit bitmaps) to crash. This was
670 due to missing 32-bit compat code in side the function
671 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
674 Fix a bug which would cause mke2fs to fail creating the journal if
675 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
678 Updated/fixed various man pages.
680 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
683 Fixed various Debian Packaging issues.
689 Change the nonsensically wrong types in the function signature of the
690 inline function ext2fs_find_first_zero_block_bitmap2(). This was
691 caused by a cut and paste error; fortunately no code in e2fsprogs used
692 this inline function, and there are any users of this functions
693 outside of e2fsprogs.
695 Add support for systems which have valloc(), but which do have
696 posix_memalign() nor memalign() (such as MacOS 10.5).
698 Refactor and clean up the allocation of aligned buffers for Direct I/O
699 support. Previously some allocations were requesting a greater
700 alignment factor that what was strictly necessary. Also optimize
701 reading and writing bitmaps using Direct I/O when the size of the
702 bitmap did not fully cover the file system blocksize.
704 Reserve the codepoints for the INCOMPAT features LARGEDATA and
707 Improved the regression test suite by adding some new integration
708 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
709 jbd2 format, as well as f_eofblocks which tests the new handling of
710 uninitialized and initialized blocks beyond i_size. Also add a new
711 unit test which verifies 32-bit bitmaps support and the new
712 find_first_zero primitives.
714 Add a few dependencies to fix parallel (make -j) builds.
716 Removed bash'isms which were breaking the regression test suite on
717 systems where /bin/sh is not bash.
719 The config.guess and config.sub have been updated to the 2012-02-10
722 Fix a portability problem caused by assuming the present of mntent.h
723 means that setmntent() exists. Instead, explicitly test for this in
724 the configure script.
726 If the sys/signal.h header file does not exist, don't try to include
727 it, since it's not available on all systems.
729 Add support for systems that do not support getpwuid_r()
731 The configure script now supports a new option,
732 --enable-relative-symlinks, which will install relative symlinks for
733 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
735 When building BSD shared libraries make sure the LDFLAGS variable is
736 passed to the linker. Fixing this allows, for example, e2fsprogs to
737 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
740 Fix gcc -Wall nitpicks
743 E2fsprogs 1.42.2 (March 27, 2012)
744 =================================
746 The resize2fs program uses much less CPU and is much faster for very
747 large file systems. (Addresses Debian Bug: #663237)
749 The seti and freei commands in debugfs can now take an optional length
750 argument to set and clear a contiguous range of inodes.
752 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
753 plan to remove support for it from the kernel file system driver. It
754 really wasn't very useful and was causing more problems than it
755 solves. Since e2fsck will complain if inodes that should have
756 EOFBLOCKS_FL do not have the flag set, we are going to remove this
757 check from e2fsprogs first, and then only remove the flag from the
760 The mke2fs program can now use direct I/O via "mke2fs -D". This will
761 slow down the mke2fs, but it makes it more polite on a loaded server
762 by limiting the amount of memory that gets dirtied by mke2fs when it
763 is using buffered I/O.
765 E2fsck was needlessly closing and re-opening the file system as a side
766 effect of adding Multiple Mount Protection (MMP). This isn't
767 necessary for non-MMP file systems, so drop it.
769 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
770 can more easily diagnose memory allocation failures caused by
771 insufficient memory. E2fsck will now abort if there are memory
772 allocation failures when the file system is initially opened and
773 during the block group descriptor checks. (Addresses Google Bug:
776 If there are incorrect block group checks, e2fsck will now report the
777 incorrect and corrected checksum values.
779 The e2fsck progam can now write log files containing the details of
780 the problems that were found and fixed directly, via configuration
781 parameters in /etc/e2fsck.conf.
783 Added the ability to limit the number of messages reported by e2fsck
784 for a given problem type. This avoids a potential bottleneck if there
785 is a serial console which can cause a boot sequence to take a long
786 time if e2fsck needs to report many, many file system errors.
788 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
789 them to use much less memory for large file systems.
791 The dumpe2fs program will now print the expected block group checksum
792 if it is incorrect. This helps to diagnose problems caused by
793 incorrect block group checksums.
795 E2fsck now checks for extents with a zero length, since the kernel
796 will oops if it comes accross such a corrupted data structure. (See
797 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
799 E2fsck has a number of bugs relating to discard that have been fixed.
800 (1) Fixed a bug which could cause e2fsck to discard portions of the
801 inode table which were actually in use. (2) E2fsck will now avoid
802 using discard if the block device doesn't zero data on discard, since
803 otherwise this could cause problems if the file system gets corrupted
804 in the future. (3) E2fsck will now avoid using discard when it is run
805 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
806 discards in the last block group.
808 E2fsck's CPU utilization in pass 5 has been optimized, which will
809 speed up e2fsck slightly.
811 E2image will now skip copying uninitialized bitmap and inode table
814 Fixed mke2fs -S so it does not corrupt the first block group's
817 E2fsck will now check the new sysfs interface to determine if we are
818 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
820 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
822 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
827 Fixed various portability issues for non-Linux systems, particularly
828 MacOS X, as well as Linux systems running with the just-released glibc
831 Fix file descriptor leak in ext2fs_close() if the file system with
832 uninit_bg is opened read/only with a backup superblock. (Addresses
833 SourceForge Bug: #3444351)
835 Fixed an invalid return in a non-void function in the quota code.
836 (Addresses SourceForge Bug: #3468423)
838 Fixed the debian rules file so that the calls to dpkg-buildflags works
839 when the shell is dash.
841 The debian package build now uses V=1 so that there is more
842 information about potential build failures in debian buildd logs.
844 If the uninit flags get cleared by functions such as
845 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
846 superblock is marked dirty and the block group descriptor checksum is
847 updated if necessary.
849 The debian rules file will now try to load debian/rules.custom of it
850 exists. This flie can skip various builds for speed reasons if there
851 is no need for the e2fsck-static or udeb packages. Available
852 customizations in the rules file includes SKIP_STATIC=yes,
853 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
855 In addition, if the file misc/mke2fs.conf.custom.in exists in the
856 source tree, it will be used instead of the standard misc.conf file in
857 the upstream sources. This makes it easier for Debian-derived systems
858 to distribute a custom mke2fs.conf file without having to worry about
859 merge issues if future versions of e2fsprogs makes changes in the
860 upstream default version of mke2fs.conf.
863 E2fsprogs 1.42.1 (February 17, 2012)
864 ===================================
866 The mke2fs and e2fsck now use significantly less memory when creating
867 or checking very large file systems. This was enabled by adding
868 extent-based bitmaps which are stored using a red-block tree, since
869 block and inode allocations tend to be contiguous.
871 The command mke2fs -S is used as a last ditch recovery command to
872 write new superblock and block group descriptors, but _not_ to destroy
873 the inode table in hopes of recovering from a badly corrupted file
874 system. So if the uninit_bg feature is enabled, mke2fs -S will now
875 set the unused inodes count field to zero. Otherwise, e2fsck -fy
876 after using mke2fs -S would leave the file system completely empty.
878 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
879 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
880 installed an mke2fs binary using that name.
882 The usage and help messages for the -G, -t and -T options in mke2fs
885 If e2fsck needs to use the backup group descriptors, the
886 ext2fs_open2() function clears the UNINIT bits to ensure all of the
887 inodes in the file systems get scanned. However, the code which reset
888 the UNINIT flags did not also recalculate the checksum, which produced
889 many spurious (and scary) e2fsck messages. This has been fixed by
890 resetting cheksums when the UNINIT bits are cleared.
892 Relax a check in e2fsck which required that the block bitmap to be
893 initialized when the inode bitmap is in use. This will allow us to
894 eventually eliminate code from the kernel which forcibly initialized
895 the block bitmap when the inode bitmap is first used, requiring an
896 extra journal credit and disk write. (Addresses Google Bug: #5944440)
898 Make sure rdebugfs (which may be installed setuid or setgid disk) does
899 not honor environment variables if euid != uid or egid != gid.
901 Debugfs's ncheck command has been optimized and now is much more
902 robust with faced with corrupted file systems. The ncheck command
903 also now has a -c option which will verify the file type information
904 in the directory entry to see if matches the inode's mode bits. This
905 is extremely useful when trying to use debugsfs to determine which
906 parts of the file system metadata can be trusted.
908 E2image will try to use ftruncate64() to set the i_size for raw
909 images, instead of writing a single null byte. This avoid allocating
910 an extra block to the raw image, for those file systems and/or
911 operating systems that support this. (Linux does.) In addition, fix
912 a logic bug that caused the file to not be properly extended if the
913 size of the last hole was exactly an multiple of a megabyte.
915 Fixed a bug in resize2fs where for 1k and 2k file systems, where
916 s_first_data_block is non-zero, this wasn't taken into account when
917 calculate the minimum file system size for use with the -M option.
919 Fixed the badblocks program to honor the -s flag when in read-only -t
920 mode. (Addresses Debian Bug #646629)
922 Update Czech, Dutch, French, Polish, and Sweedish translation from the
925 Fixed various Debian Packaging issues so that dpkg-buildflags is used
926 if present, which allows e2fsprogs to be built with security hardening
927 flags. (Addresses Debian Bugs: #654457)
932 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
933 This was only an issue for programs compiled against e2fsprogs 1.41
934 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
937 The libext2fs library now uses sysconf() to fetch the page size, instead
938 of the deprecated getpagesize().
940 The ext2fs_get_pathname() function will return a partial path if an a
941 directory in the path is not a directory, displaying it as an inode
942 number in angle brackets instead of giving up and displaying an error.
943 This is much more helpful when a user is trying to debug a corrupted
946 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
948 Added a new library function, ext2fs_file_get_inode_num(), for use by
951 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
952 file, it actually works.
954 The block iterator now properly honors the BLOCK_ABORT flag for
955 extent-based flags. Previously, it didn't, which generally made code
956 be less efficient, but it could cause bugs in ext2fs_link(), for
957 example, by causing it to insert multiple directory entries.
959 Fixed an (harmless other than causing a compiler warning) use of an
960 uninitialized variable in e2fsck's MMP code.
963 E2fsprogs 1.42 (November 29, 2011)
964 ==================================
966 This release of e2fsprogs has support for file systems > 16TB. Online
967 resize requires kernel support which will hopefully be in Linux
968 version 3.2. Offline support is not yet available for > 16TB file
969 systems, but will be coming.
971 This release of e2fsprogs has support for clustered allocation. This
972 reduces the number of block (now cluster) bitmaps by allocating and
973 deallocating space in contiguous power-of-2 collections of blocks,
974 which are called clustered. This is a file system level feature,
975 called 'bigalloc', which must be enabled when the file system is
976 initially formatted. It is not backwards compatible with older
979 Added support for the Multi-Mount Protection (MMP) feature.
981 E2fsck more efficiently uses scratch files for really big file
982 systems. (This is a feature that has to be turned on explicitly; see
983 [scratch_files] in the e2fsck.conf man page.)
985 Fix a bug in e2fsck where if the free blocks and inodes counts are
986 incorrect, e2fsck would fix them without printing an error message.
987 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
988 any explanation of what was fixed.
990 E2fsck will no longer attempt to clone an extended attribute block in
991 pass1b handling if the file system does not support extended
994 E2fsck will be more careful accidentally asking the user to continue
995 if the file system is mounted, so that an escape sequence won't cause
996 a false positive. (Addresses Debian Bug: #619859)
998 E2fsck now uses less cpu time in pass 5 when large portions of the
999 bitmaps are uninitialized.
1001 E2fsck will no longer segault when a corrupted file system has a bad
1002 extent, and removing it leads to a block needing to be deallocated.
1003 (Addresses SourceForge Bug: #2971800)
1005 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
1006 and print debugging information to make it easier to find potential
1009 E2fsck will check to see if the bad block inode looks insane, and will
1010 skip trying to use if it certain fields which should be zero look
1011 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
1012 to get confused and do more harm than good.
1014 If e2fsck modifies certain superblock fields which the kernel doesn't
1015 look at, it will now mark the superblock as dirty without marking the
1016 file system as changed. This avoids signalling the init scripts that
1017 a reboot is necessary, since the kernel isn't going to look at those
1018 fields, so it won't care if they have been changed.
1020 Fixed a bug in the libext2fs library (in the binary search routine of
1021 the icount abstraction) that could (very, very rarely) cause e2fsck to
1022 die in the middle of pass 1 or pass 2 processing.
1024 E2fsck will not try to do a discard operation if the -n option was
1025 specified on the command line.
1027 E2fsck now supports an extended "discard" option which will cause
1028 e2fsck to attempt discard all unused blocks after a full, successful
1031 E2fsck will check for the bad block inode to make sure it looks sane
1032 before trusting it, to avoid causing more harm than good to the file
1035 E2fsck now returns additional status bits in its exit code if it
1036 aborts early in the e2fsck run.
1038 E2fsck now correctly calculates the maximum file size in the case of
1039 the huge_file file system feature enabled without extents.
1041 The mke2fs and e2fsck programs now tries to use the punch hole command
1042 as a "discard" when operating on normal files.
1044 The e2image program now supports the qcow2 format, which is a more
1045 efficient way of capturing file system dumps.
1047 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
1048 per-device defaults to be specified in the configuration file.
1050 Mke2fs now supports the reserved_ratio relation in the [defaults] and
1051 [fs_types] section in mke2fs.conf.
1053 Mke2fs now creates extent-mapped directories for the root and
1054 lost+found directories.
1056 Mke2fs will skip zero'ing the journal if the extended option
1057 "lazy_journal_init" is specified. This can save a lot of time, but it
1058 does add a small amount of risk if the system crashes before the
1059 journal is overwritten entirely once. It is epsecially useful for
1062 Mke2fs will now create file systems that enable user namespace
1063 extended attributes and with time- and mount count-based file
1064 system checks disabled.
1066 Mke2fs will not set a stride or strip size of one block based on block
1067 device attributes obtained from sysfs.
1069 Mke2fs now displays a progress report during the discard process.
1071 Mke2fs now handles extreme file system parameters correctly which
1072 previously caused the inodes per group to drop below 8, leading to a
1073 segfault. (The inodes per group must be a multiple of 8, but the code
1074 didn't correctly deal with an inodes per group count less than 8.)
1076 Mke2fs and tune2fs previously would give an error if the user tried
1077 setting the stride and stripe-width parameters to zero; but this is
1078 necessary to disable the stride and stripe-width settings. So allow
1079 setting these superblock fields to zero. (Addresses Google Bug:
1082 Mke2fs now gives a warning if the auto-detected block size exceeds the
1085 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
1086 is the default), mke2fs will now set the s_max_mnt_count superblock
1087 field to -1, instead of 0. Kernels older then 3.0 will print a
1088 spurious message on each mount then they see a s_max_mnt_count set to
1089 0, which will annoy users. (Addresses Debian Bug: #632637)
1091 The default mke2fs.conf now has entries for "big" and "huge", which
1092 are needed for very big file systems.
1094 The resize2fs program now has support for a new online resize ioctl
1095 that can support file systems > 16TB, once it arrives in v3.x kernels.
1097 Fixed bug which caused resize2fs to fail when shrinking an empty file
1098 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
1100 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
1102 Allow tune2fs to remove external journals if the device can not be
1105 Debugfs's icheck will now correctly find inodes which use the
1106 searched-for block as an extended attribute block.
1108 Debugfs now has a new "punch" command which remove blocks from the
1111 Debugfs now has a new "e2freefrag" command which analyzes the free
1112 space fragmentation of the file system, using the same code as the
1115 Debugfs now has a "filefrag" command which displays information about
1116 a file's fragmentation.
1118 Add support to build a metadata-only, read-only, stripped-down version
1119 of debugfs called rdebugfs.
1121 Fixed a potential stack overrun bug in debugfs.
1123 The badblocks program now correctly recovers from I/O errors when
1124 direct I/O is being used. The badblocks command now also supports a
1125 -B option which forces the use of buffered I/O, and the -v option will
1126 provide a more detailed breakdown of read, write, and failed
1129 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
1131 Added support for journals larger than 2GB.
1133 Support using both hard links and symlinks when installing e2fsprogs.
1135 Add overflow checking to tune2fs -i's fsck interval, which must fit in
1138 The debugfs command now has a new 'blocks' command which prints out
1139 data blocks of a particular inode in a format which is useful for
1142 Filefrag will report 0 extents correctly in verbose mode. (Addresses
1143 RedHat Bugzilla: #653234)
1145 Filefrag has been fixed so its -v report prints the correct expected
1146 block number (previously there had been an off-by-one error). In
1147 addition, it will now display the number of contiguous extents when -v
1148 is not specified. This makes it consistent with the number of extents
1149 printed when the -v option was specified. In addition, the number of
1150 contiguous extents is far more interesting/useful than the number of
1151 physical extents for very large files. (Addresses Debian Bug:
1154 Logsave's usage message has been fixed. (Addresses Debian Bug:
1157 Avoid an infinite loop in ext2fs_find_block_device() if there are
1158 symlink loops in /dev caused by a buggy udev.
1160 Added a useful "fallocate" program to the contrib directory.
1162 Fixed an ABI compatibility problem in libext2fs which broke the dump
1163 program. Also added back some macros which dump needed so it could
1164 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
1167 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
1168 Debian Bug: #641667)
1170 Added internationalization support for libcom_err error table strings.
1172 Fixed various spelling mistakes found in various output strings found
1173 by I18N translators.
1175 Update translations: French, Chinese, Germany, Indonesian, Swedish,
1176 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
1179 Fixed various Debian Packaging issues. (Addresses Debian Bugs:

1182 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
1188 Initial support for quota as an integrated feature, where the quota

1190 e2fsck is present, although disabled by default. It must be enabled
1191 by using the configure option --enable-quota.
1193 Reserved the on-disk fields for the metadata checksum and snapshot
1194 features, which are currently in development.
1196 The ext2fs library now has the new functions ext2fs_punch(),
1197 ext2fs_get_memzero() and ext2fs_file_get_inode().
1199 The ext2fs library now has support for calculating the crc32c checksum
1200 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
1202 The I/O manager now supports the discard operation.
1204 Reserved file system code points for new 1st class quota feature.
1206 Shortened the compilation lines by moving the autoconf defines to
1207 a config.h header file.
1209 Fixed a potential free of an unitialized pointer in
1210 ext2fs_update_bb_inode().
1212 Fixed miscellaneous gcc -Wall and coverity warnings.
1214 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
1216 Fixed a build failure when OMIT_COM_ERR is defined.
1218 Improved error checking and fixed memory leaks caused by error return
1221 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
1222 the fsync() to be skipped.
1224 Added a test for extent-mapped journals by mke2fs and tune2fs.
1226 Added a test for creating a large (over 4GB) journal using mke2fs.
1228 Added a test to make sure the inode size remains constant.
1230 The regression test script now prints the list of which tests failed.
1232 The regression test system now uses /tmp for its scratch files, which
1233 is often a tmpfs mounted file system and hence much faster.
1235 The i_e2image test was fixed so it works with valgrind.
1237 Tests that rely on debugfs are now skipped if debugfs wasn't built.
1239 Fixed the dependencies for "make check" so all required dependencies
1240 are built before running the gression tests.
1242 A link to com_err.h is installed in $(includedir) during a "make install".
1244 The po/*.gmo files are automatically rebuilt if they are missing or
1245 out of date. This helps out Debian packaging.
1247 Allow ext2fs_get_memalign() to compile on systems that don't have
1250 Fixed a namespace leak in libext2fs (tdb_null).
1253 E2fsprogs 1.41.14 (December 22, 2010)
1254 =====================================
1256 Fix spurious complaint in mke2fs where it would complain if the file
1257 system type "default" is not defined in mke2fs.conf.
1259 The resize2fs program will no longer clear the resize_inode feature
1260 when the number reserved group descriptor blocks reaches zero. This
1261 allows for subsequent shrinks of the file system to work cleanly for
1262 flex_bg file systems.
1264 The resize2fs program now handles devices which are exactly 16T;
1265 previously it would give an error saying that the file system was too
1268 E2fsck (and the libext2fs library) will not use the extended rec_len
1269 encoding for file systems whose block size is less than 64k, for
1270 consistency with the kernel.
1275 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
1276 been fixed. (Addresses Sourceforge Bug: #3138115)
1278 The ext2fs_block_iterator2() function passed an incorrect ref_offset
1279 to its callback function in the case of sparse files. (Addresses
1280 Sourceforge Bug: #3081087)
1282 Fix some type-punning warnings generated by newer versions of gcc.
1285 E2fsprogs 1.41.13 (December 13, 2010)
1286 =====================================
1288 E2fsck now supports the extended option "-E journal_only", which
1289 causes it to only do a journal replay. This is useful for scripts
1290 that want to first replay the journal and then check to see if it
1293 E2fsck will now support UUID= and LABEL= specifiers for the -j option
1294 (which specifies where to find the external journal). (Addresses
1297 E2fsck now has support for the problems/<problem code>/force_no
1298 configuration option in e2fsck.conf, which forces a problem to not be
1301 Dumpe2fs will now avoid printing large negative offsets for the bitmap
1302 blocks and instead print a message which is a bit more helpful for
1303 flex_bg file systems.
1305 Mke2fs will now check the file system type (specified with the -t
1306 option) to make sure it is defined in the mke2fs.conf file; if it is
1307 not, it will print an error and abort. If the usage type (specified
1308 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
1309 warning but will continue. (Addresses Debian Bug #594609)
1311 Clarified error message from resize2fs clarifying that on-line
1312 shrinking is not supported at all. (Addresses Debian Bug #599786)
1314 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
1315 displayed. (Addresses Debian Bug #555456)
1317 E2fsck will open the external journal in exclusive mode, to prevent
1318 the journal from getting truncated while it is in use due to a user
1319 accidentally trying to run e2fsck on a snapshotted file system volume.
1320 (Addresses Debian Bug #587531)
1322 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
1325 The tune2fs program can now set the uninit_bg feature without
1328 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
1329 default mount options settings which were added in 2.6.35.
1331 The e2fsck and dumpe2fs programs now support the new ext4 superblock
1332 fields which track where and when the first and most recent file
1333 system errors occurred. These fields are displayed by dumpe2fs and
1334 cleared by e2fsck. These new superblock fields were added in 2.6.36.
1336 Debugfs now uses a more concicse format for listing extents in its
1337 stat command. This format also includes the interior extent tree
1338 blocks, which previously was missing from stat's output for
1341 Debugfs has a new option, -D, which will request Direct I/O access of
1344 Mke2fs will skip initializing the inode table if a device supports
1345 discard and the discard operation will result in zero'ed blocks.
1347 Badblocks will now correctly backspace over UTF-8 characters when
1348 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
1349 Debian Bugs #583782 and #587834)
1351 E2freefrag will now display the total number of free extents.
1353 Resize2fs -P no longer requires a freshly checked filesystem before
1354 printing the minimum resize size.
1356 Fixed a floating point precision error in a binary tree search routine
1357 that can lead to seg fault in e2fsck and resize2fs.
1359 Fixed a bug in e2fsck where if both the original and backup superblock
1360 are invalid in some way, e2fsck will fail going back to the original
1361 superblock because it didn't close the backup superblock first, and
1362 the exclusive open prevented the file system from being reopened.
1364 Fixed a big in e2freefrag which caused getopt parsing to fail on
1365 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
1367 Clarified an mke2fs error message so a missed common in an -E option
1368 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
1369 results in a more understandable explanation to the user.
1371 Mke2fs now displays the correct valid inode ratio range when
1372 complaining about an invalid inode ratio specified by the user.
1374 Mke2fs now understands the extended option "discard" and "nodiscard",
1375 and the older option -K is deprecated. The default of whether
1376 discards are enabled by default can be controled by the mke2fs.conf
1379 Mke2fs's handling of logical and physical sector sizes has been
1380 improved to reflect the fact that there will be some SSD's with 8k and
1381 16k physical sectors arriving soon. Mke2fs will no longer force block
1382 size to be the physical sector size, since there will be devices where
1383 the physical sector size is larger than the system's page size, and
1384 hence larger than the maximal supported block size. In addition, if
1385 the minimal and optimal io size are not exported by the device, and
1386 the physical sector size is larger than the block size, the physical
1387 sector size will be used to set the Raid I/O optimization hints in the
1390 E2fsck will now display a better, more specific error message when the
1391 user enters a typo'ed device name, instead of blathering on about
1392 alternate superblocks.
1394 Fixed various Debian Packaging Issues
1396 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
1397 #589345, #591083; Addresses Launchpad Bug: #505719)
1399 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
1400 Polish, Swedish, and Vietnamese translations.
1406 Fix a dependency definition for the static and profiled blkid
1407 libraries which could cause compile failures in some configurations.
1408 (Addresses Debian Bug: #604629)
1410 Add support for Direct I/O in the Unix I/O access layer.
1412 Fixed a memory leak in the Unix I/O layer when changing block sizes.
1414 Fixed minor memory leaks in mke2fs.
1416 Added a new function to the ext2fs library, ext2fs_get_memalign().
1418 The tst_super_size test program will check to make sure the superblock
1419 fields are correctly aligned and will print them out so they can be
1420 manually checked for correctness.
1422 Fixed some makefile dependencies for test programs in lib/ext2fs.
1424 Reserved the feature flags and superblock fields needed for the Next3
1427 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
1428 EXT4_INCOMPAT_EA_INODE.
1431 E2fsprogs 1.41.12 (May 17, 2010)
1432 ================================
1434 Mke2fs now gives a correct error message if the external journal
1435 device is not found. (Addresses Red Hat Bug #572935)
1437 Resize2fs -P will now refuse to print a minimum size if the file
1438 system is not clean. Previously it would go ahead and print a minimum
1439 size anyway, which might not be correct, leading to user confusion.
1441 E2fsck now tests for extents that begin at physical block 0 and
1442 rejects them as invalid. (Addresses Google Bug: #2573806)
1444 Fixed a bug in e2fsck which could cause it to crash when trying to
1445 remove an invalid extent and the block bitmaps hadn't yet been loaded.
1446 (Addresses SourceForge Bug: #2971800)
1448 E2fsck now will completely skip time-based checks if the system clock
1449 looks insane or the option broken_system_clock is set in
1452 E2fsck would previously report an i_blocks corruption for a 4T file
1453 created using posix_fallocate; this bug has been fixed.
1455 E2fsck will now correctly mark a sparse journal as invalid and will
1456 delete and recreate the journal to address the problem.
1458 E2fsck would previously incorrectly ask the user whether she would
1459 like to abort the file system check after finding a problem --- and
1460 then abort regardless of the user's answer. This is annoying, and
1463 E2fsck can now continue even if it fails to recreate the resize
1464 inode; previously it would just abort the file system check
1467 E2fsck could potentially remove directory entries for inodes found in
1468 the unused region of the inode table; this would generally happen on
1469 ext4 file systems that do not use journaling. This bug has been fixed
1470 by not clearing these directory entries once it has been established
1471 that bg_unused_inodes may not be trustworthy; once pass #2 has been
1472 completed, e2fsck will restart the file system check from the
1473 beginning, and then it will be safe to delete any directory entries
1474 pointing to inodes that appear to be deleted. (Addresses Google Bug:
1477 E2fsck will not try to set the block group checksums if the user
1478 cancels the fsck with a control-C. It's a bad idea to set the
1479 checksums if e2fsck hasn't been completed, and it often results an the
1480 error message, "Inode bitmap not loaded while setting block group
1481 checksum info". (Addresses Launchpad Bug: #582035)
1483 The mke2fs program now queries the kernel for the physical as well as
1484 the logical sector size, and will not allow a blocksize below the
1485 logical, and will strongly encourage a blocksize at least as big as
1486 the physical blocksize. This is needed for 4k sector drives that
1487 emulate 512 byte sector sizes.
1489 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
1490 rarely needed, but it is a legal value.
1492 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1493 not needed, and offer to clear it; this is a sign of a kernel bug, but
1494 more importantly, some released kernels may crash when this situation
1495 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
1497 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1498 i_size is correct. (Kernels starting with 2.6.34 will set
1501 The com_err library will now only output ^M (a CR character) when the
1504 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
1505 and Vietnamese translations.
1507 Fixed various Debian packaging issues --- see debian/changelog for
1508 details. (Addresses Debian Bugs: #571247, #563487)
1514 The regression test suite now uses its own mke2fs.conf file, so that
1515 downstream distributions want change the mke2fs.conf file which is
1516 distributed in the RPM or dpkg file, without worrying about screwing
1517 up the regression test results.
1519 Always build namei.o so that building with configure --disable-debugfs
1520 works correctly. Long-term, if we care about reduced e2fsprogs
1521 builds, we need a more general solution for deciding what .o files are
1522 needed for a particular build. Given that install floppies are going
1523 (gone?) the way the dodo bird, we probably don't care, though.
1524 (Addresses Sourceforge Bug: #2911433)
1526 Add configure options --enable-symlink-build and
1527 --enable-symlink-install, which allow e2fsprogs be built using
1528 symlinks instad of hard links, and to be installed using symlinks
1529 instead of hard links, respectively. It is useful when the file
1530 system where the build is taking place, or the file system where
1531 e2fsprogs is installed, can't handle hard links for some reason.
1532 (Addresses Sourceforge Bug: #1436294)
1534 Fixed compile warning in mke2fs.c.
1537 E2fsprogs 1.41.11 (March 14, 2010)
1538 ==================================
1540 E2fsck will no longer give a fatal error and abort if the physical
1541 device has been resized beyond 2**32 blocks. (Addresses Launchpad
1544 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
1545 the allocation status of the block <blk>. (Addresses Debian Bug:
1548 E2fsck now prints a much more emphatic and hopefully scary message
1549 when a file system is detected as mounted while doing a read/write
1550 check of the filesystem. Hopefully this will dissuade users from
1551 thinking, "surely that message doesn't apply to *me*" :-(
1553 E2fsck -n will now always open the file system read-only. We now
1554 disallow certain combination of options which previously were manual
1555 exceptions; this is bad because it causes users to think they are
1556 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
1557 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
1559 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
1560 it detected a badly aligned partition. Unfortunately, this broke some
1561 distribution installation scripts, so it now just prints the warning
1562 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
1563 Launchpad Bug: #530071)
1565 Mke2fs would take a long time to create very large journal files for
1566 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
1569 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
1570 2.6.34 kernels to make e2fsck not complain about blocks deliberately
1571 fallocated() beyond an inode's i_size.
1573 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1574 e2fsck -fD can corrupt non-indexed directories when are exists one or
1575 more file names which alphabetically sort before ".". This can happen
1576 with ext2 filesystems or for small directories (take less than a lock)
1577 which contain filenames that begin with a space or some other
1578 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
1585 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works

1598 Add libss support for libreadline.so.6.
1600 Fix e2fsck's check for extent-mapped directory with an incorrect file
1603 Add new e2fsck.conf configuration option, default/broken_system_clock
1604 to support systems with broken CMOS hardware clocks. Also, since too
1605 many distributions seem to have broken virtualization scripts now,

1614 of fixing file system problems. This reduces the number of spurious

1621 sparse directories which use extents).
1623 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
1625 Fix a bug in filefrag where on platforms which can allow file systems
1626 with 8k blocks, that it doesn't core dump when it sees a file system
1627 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
1630 E2fsck will correctly fix directories that are have an inaccurate
1631 i_size as well as other problems in a single pass, instead of

1664 have the HUGE_FILE_FL flag set.
1666 Fix e2fsck's handling of 64-bit i_blocks fields.
1668 E2fsck will now print "Illegal indirect block", "Illegal
1669 double-indirect block", etc., instead of "Illegal block #-1" or
1670 "Illegal block #-2", etc. This makes it easier for users to
1671 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)

1728 E2fsprogs 1.41.9 (August 22, 2009)
1729 ==================================
1731 Fix a bug in e2fsck routines for reallocating an inode table which
1732 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1733 filesystem feature with a relatively rare (and specific) filesystem
1734 corruption. This fix causes e2fsck to try to find space for a new
1735 portion of the inode table in the containing flex_bg, and if that
1736 fails, the new portion of the inode table will be allocated in any
1737 free space available in the filesystem.
1739 Make e2fsck less annoying by only asking for permission to relocate a
1740 block group's inode table once, instead of for every overlapping
1741 block. Similarly, only ask once to recompute the block group
1742 checksums, instead of once for each corrupted block group's checksum.
1744 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1745 not present, and it needs to fall back to using the FIBMAP ioctl.
1747 Fix filefrag to correctly print the number of extents for zero-length
1748 files. (Addresses Debian Bug: #540376)
1750 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1751 to more easily debug the FIBMAP code.
1753 Fixed filefrag for non-extent based files.
1755 Add a new program, e2freefrag, which displays information about the
1756 free space fragmentation in an ext2/3/4 filesystem.
1758 Fix inode resizing via tune2fs -I so that it works correctly in the
1759 face of non-empty bad blocks inodes, and if the filesystem was
1760 formatted using the "mke2fs -E stride=N" option for RAID arrays.
1762 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1763 and corrupt large directories if the directory needs to shrink by more
1764 than one block. (Addresses Debian Bug: #537510)
1766 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1767 last mount times are in the future, they are corrected even if
1768 buggy_init_scripts is set. This is needed because otherwise resize2fs
1769 will refuse to resize the filesystem, even after running "e2fsck -f".
1770 (Addresses Launchpad bug: #373409)
1772 E2fsck will now print much fuller information when the last mount time
1773 or last written time is in the future, since most people can't seem to
1774 believe their distribution has buggy init scripts, or they have a
1775 failed CMOS/RTS clock battery.

1817 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
1818 setgid and the currently running program doesn't have write access to
1819 the uuidd work directory.
1821 Add safety checks (for non-Linux systems) so that uuidd isn't run with
1822 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1823 will be careful not to close the file descriptor for its unix domain
1824 socket when it detaches itself from the controlling tty. Also add
1825 safety checks so that if the unix domain socket between the uuid
1826 library and uuidd program is closed for any reason, both the library
1827 and the uuidd will return an appropriate error code instead of looping
1828 in an infinite loop.
1830 The e2croncheck script, which creates an LVM snapshot and then checks
1831 the ext3/4 filesystem via the LVM snapshot, has been added to the

1865 E2fsprogs 1.41.7 (June 29, 2009)
1866 ================================
1868 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
1869 uninitalized data into the portion of the inode beyond the first 128
1870 bytes when operating on inodes mapped via extents; potentially
1871 corrupting filesystems.
1873 Fix memory leaks in e2fsprogs, including a very large memory leak
1874 which can cause e2fsck to run out of memory when checking very large
1875 filesystems using extents.
1877 The logsave program will now filter out the ^A and ^B characters when
1878 writing to the console.
1880 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
1881 end of the block even if the directory block is corrupted.
1883 Fix debugfs from core dumping if the logdump command fails to open the
1886 Enhance badblocks to print the currently tested block number when
1887 interrupted with ^C.
1889 Fix lsattr to exit with a non-zero status when it encounters errors.

1892 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
1893 filesystems as the kernel when encoding rec_len >= 64k. For 64k
1894 filesystems (currently all that is supported by e2fsprogs, this is
1895 only a minor corner case).
1897 Resize2fs will now update the journal backup fileds in the sup0erblock
1898 if the journal is moved; this avoids an unnecessary full fsck after
1899 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)

1921 valgrind with the appropriate options to find memory leaks.
1924 E2fsprogs 1.41.6 (May 30, 2009)
1925 ===============================
1927 Fix a critical regression in e2fsck introduced version 1.41.5 which
1928 can undo updates to the block group descriptors after a journal replay.
1930 If e2fsck receives an I/O error while replaying the journal, prompt
1931 the user whether they want to ignore the error or not; if e2fsck is
1932 run in preen mode, force fsck to abort the preen pass.
1934 Fix a bug which would cause e2fsck to core dump if the filesystem
1935 contains a corrupt extent header, and the user declines to clear the
1936 inode. (Addresses Sourceforge Bug: #2791794)
1938 Fix e2fsck to restart only once in the case of multiple block groups
1939 which inodes in use that are in the uninitialized part of the block
1940 group's inode table.
1942 To reduce user confusion, if the /etc/mtab file is missing
1943 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1944 new, explicit error code to indicate this case. This will cause
1945 e2fsck to give a clearer error message when the user is using buggy
1946 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
1949 Fix e2fsck so that if the primary group descriptors are corrupted, but
1950 the backup superblock is entirely invalid, to go back to using (and
1951 fixing) the priary group descriptors instead of completely giving up
1952 on the filesystem. (Addresses Debian Bug: #516820)
1954 Change e2fsck to not abort a preen pass if an inode is found to have
1955 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
1956 kernels (post 2.6.29) will ignore this field. So let's fix it
1957 automatically during the preen pass instead of forcing the user to fix
1958 this up manually. (Addresses Debian Bug: #526524)
1960 Add resource tracking for e2fsck passes 1b through 1d.
1962 Speed up e2fsck by eliminating unnecessary journal checks if the
1963 filesystem is already mounted and doesn't need recovery (since the
1964 kernel would have run the journal when the filesystem was mounted.)
1965 Also speed up e2fsck by avoiding unnecessary block group descriptor
1966 updates in ext2fs_close().
1968 Add support to chattr to migrate inodes from using direct/indirect
1971 Avoid corrupting the filesystem if there is an attempt to shrink a
1972 filesystem using resize2fs smaller than posible by making
1973 ext2fs_set_bmap() more careful not to delete the old block until the
1974 new block can be inserted. In addition, fix a bug in how the minimum
1975 size of the filesystem (plus a safety margin) is calculated, and
1976 modify resize2fs to refuse to shrink the filesystem below that minimum
1977 size without the force flag.
1979 Teach blkid to try to figure out DM device names using take advantage
1980 of information in sysfs when running on kernels (2.6.29 and later)
1981 which provide this information in /sys/block/dm-<N>/dm/name; this is
1982 much faster than scanning for the devncie number in /dev/mapper.
1984 Fix blkid to prefer /dev/mapper/<name> device names instad of the
1985 private /dev/dm-X names.
1987 Add an -a option to debugfs's close_filesys command which writes any
1988 changes to the superblock or block group descriptors to all of the
1989 backup superblock locations.
1991 Add support to the filefrag program to use the FIEMAP ioctl.
1993 Update Chinese translation from the Translation Project.
1995 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
1996 Launchpad Bug: #381854)
1998 Fixed various Debian packaging issues --- see debian/changelog for
1999 details. (Addresses Debian Bug #506064)
2005 Add test code to make sure e2fsck's problem.c doesn't have two problem
2006 codes assigned to duplicate values.
2008 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.

2011 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
2012 function declaration for init_resource_track() and
2013 print_resource_track() when RESOURCE_TRACK is not defined.
2015 The test code which is used to build the tst_csum progam has been
2016 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
2017 avoid compile problems caused by not having a prototype for
2018 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
2020 Update the config.guess and config.sub file to the latest from the
2021 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
2022 Debian Bug: #528330)
2024 Add a new function, ext2fs_extent_open2(), which behaves like
2025 pext2fs_extent_open(), but uses the user-supplied inode structure
2026 when opening an extent instead of reading the inode from disk.
2029 E2fsprogs 1.41.5 (April 23, 2009)
2030 =================================
2032 Fix a number of filesystem corruption bugs in resize2fs when growing
2033 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
2036 Debugfs can now set i_file_acl_high via the set_inodes_field command,
2037 and print a 64-bit file acl. This is useful for debugging filesystem
2038 corruptions where the high bits of i_file_acl_high are set. E2fsck
2039 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
2040 since some Linux kernel versions pay attention to this field even when
2043 Speed up e2fsck when checking clean filesystems by avoiding
2044 unnecessary block reads, and coalescing the block group descriptor
2045 blocks so they are read using a single read operation.
2047 The libuuid library will now close all file descriptors before running
2048 uuidd. This avoids problems when the calling program has open sockets
2049 which then never get closed because uuidd is a long-running helper
2050 daeomn. (Addresses Launchpad bug: #305057)
2052 In order to avoid unnecessary full filesystem checks by e2fsck after
2053 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
2054 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
2056 Mke2fs will avoid trying to create the journal when run in
2057 superblock-only mode (mke2fs -S), since the left-over journal in the
2058 inode table will cause mke2fs to fail.
2060 Fix a bug in libext2fs functions that check to see if a particular
2061 device or filesystem image is mounted, which would cause these
2062 functions to report that a file identical to the (relative) pathname
2063 used by a pseudo-filesystem was mounted when in fact it was not.
2065 Update Czech translation from the Translation Project.
2067 Add Chinese (simplified) translation from the Translation Project.
2069 Fix support for external journals (which was broken in e2fsprogs
2072 Fix a regression in debugfs where the "stat" command when no
2073 filesystem was open would cause debugfs to crash with a segmentation
2076 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
2077 used to support filesystems without a journal. Update the blkid
2078 library so it understands this.
2080 The blkid library will remove an entry from the blkid cache
2081 representing the entire disk if partitions are found, since presuambly
2082 the device previously had no partition table, but has now transitioned
2083 to using a partition table.
2085 Add a check to mke2fs and tune2fs that the argument to the -m option
2086 (which specifies the reserved ratio) must be greater than zero.
2087 (Addresses Debian Bug: #517015)
2089 Add support for tracking the number kilobytes written to the
2090 filesystem via the superblock field s_kbytes_written. It will be
2091 updated by the kernel as well as by e2fsprogs programs which write to
2092 the filesystem. This is useful for tracking the wear to filesystems
2093 on Solid Sstate Drives.
2095 Fix compatibility issue in the libext2fs info file and makeinfo
2096 version 4.12. (Addresses Red Hat Bugzilla: #481620)

2112 Add support for building the blkid command statically.
2114 Add support for disabling the built-in blkid library in favor of a
2115 system-installed blkid implementation via the configure option
2119 E2fsprogs 1.41.4 (January 27, 2009)
2120 ===================================
2122 Fixed a bug which could sometimes cause blkid to return an exit value
2123 of zero for a non-existent device (Addresses Debian Bug: #502541)
2125 Blkid will now recognize ext3 filesystems that have the test_fs flag
2126 set as ext3 filesystems.
2128 The blkid library will now recognize btrfs filesystems and swap
2129 devices currently used by user-level software suspend.
2131 Tune2fs now updates the block group checksums when changing the UUID
2132 to avoid causing e2fsck to complain vociferously at the next reboot.
2134 Tune2fs's inode size resizing algorithms have been fixed so it is not
2135 vastly inefficient for moderate-to-large filesystems, due to some
2136 O(n**2) and O(n*m) algorithms that didn't scale well at all.
2138 Fix tune2fs's inode resizing algorithm so it will not corrupt
2139 filesystems laid out for RAID filesystems; in addition, tune2fs will
2140 refuse to change the inode size for filesystems that have the flex_bg
2141 feature enabled. (This is a limitation in the current implementation
2144 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
2145 filesystems with 32-bit block numbers, when the headers for 64-bit
2146 block numbers was added. This regression has been fixed.
2148 Debugfs's ncheck command has been fixed to avoid printing garbage
2149 characters at the end of file names.
2151 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
2152 when shrinking filesystems with uninit_bg feature would not be moved.
2153 In addition, blocks and inode table blocks were not being correctly
2154 freed when shrinking filesystems with the flex_bg feable, which caused
2155 resize2fs -M to fail. Finally, when blocks are moved, make sure the
2156 uninitialized flag in extents is preserved.
2158 Fix bug which caused dumpe2fs to abort with an error if run on a
2159 filesystem that contained an external journal.
2161 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
2162 for this in argv[0] to provide better legacy support for these
2163 distributions. This is a practice that should NOT be continued,
2166 Mke2fs now has a new option -U, which allows the user to specify the
2167 UUID that should be used for the new filesystem.
2169 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
2170 minus one block. This allows users who have read that ext3 supports
2171 up to 16TB filesystems and who create a 16TB LVM to not get confused,
2172 since the true limit is really 16TB minus one block.
2174 E2fsck will no longer abort an fsck run if block group has an errant
2177 E2fsck now distinguishes between fragmented directories and fragmented
2178 files in verbose mode statistics and in the fragcheck report.
2180 Fix a bug in e2fsck which casued it double count non-contiguous
2181 extent-based inodes.
2183 E2fsck will leave some slack space when repacking directories to allow
2184 room for a few directory entries to be added without causing leaf
2185 nodes to be split right away.
2187 Fix a bug which caused e2fsck to crash when it comes across a
2188 corrupted interior node in an extent tree with the error message:
2189 "Error1: Corrupt extent header on inode XXXXXX"
2191 E2fsck problem descriptions involving the journal are no longer
2192 referred to as "ext3" problems, since ext4 filesystems also have
2195 Fix a long-standing bug in e2fsck which would cause it to crash when
2196 replying journals for filesystems with block sizes greater than 8k.
2198 Update Catalan translation from the Translation Project.
2200 Fixed various Debian packaging issues --- see debian/changelog for
2201 details. (Addresses Debian Bugs: #503057, #502323, #511207)
2206 Fix build of e2fsck.profiled, and add support for building profiled
2207 binaries in the misc directory if configured with --enable-profile.
2209 The ext2fs_open() function now performs more sanity checks on the
2210 superblock to avoid potential divide by zero errors by other parts of
2213 The ext2fs_read_inode_full() function now has a safety check to avoid
2214 a segmentation fault on corrupted filesystems.
2216 The ext2fs_new_inode() function now has a sanity check so that if the
2217 s_first_inode field in the superblock is insane, it will return
2218 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
2220 To avoid segmentation faults, ext2fs_block_alloc_stats() and
2221 ext2fs_inode_alloc_stats() now validates the passed inode or block
2222 number to avoid overrunning an array boundary.
2224 Various signed/unsigned errors for variables containing block numbers
2227 Accomodations for gcc's stupidity in not realizing that constant
2228 strings that do not contain a '%' character are safe to use in format
2229 strings have been made so that distributions that want to compile
2230 e2fsprogs with -Werror=format-security have an easier time doing so.
2232 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
2234 Added the utility make-sparse.c to the contrib directory.
2236 The ext2fs_block_iterate2() function now reflects errors from
2237 ext2fs_extent_set_bmap() to the caller, if the callback tries to
2238 change a block on an extent-based file, and ext2fs_extent_set_bmap()
2239 fails for some reason (for example, there isn't enough disk space to
2240 split a node and expand the extent tree.
2242 The ext2fs_block_iterate2() function will preserve the uninit flag in
2243 extents when the callback function modifies a block in an extent-based
2246 E2fsck will now flag filesystems that have an insane s_first_ino field
2247 in their superblock, and attempt to use a backup superblock to repair
2251 E2fsprogs 1.41.3 (October 12, 2008)
2252 ===================================
2254 E2fsck has been fixed so it prints the correct inode number for
2255 uinit_bg related problems.
2257 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
2258 is available on linux. This can be disabled via a configuration
2259 option in /etc/e2fsck.conf.
2261 Fix a file descriptor leak in libblkid when checking to see if an ext4
2262 or ext4dev module exists.
2264 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
2265 while trying to close a filesystem can lead to infinite loops.
2266 (Addresses Red Hat Bugzilla #465679)
2268 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
2269 will cause resize2fs to drop into an infinite loop. (Addresses Red
2270 Hat Bugzilla: #465984)
2272 Add a check in the Unix I/O functions in libext2fs so that when a
2273 device is opened read/write, return an error if the device is
2274 read-only using the BLKROGET ioctl.
2276 Fix debugfs's ncheck command so that it prints all of the names of
2277 hardlinks in the same directory.
2279 Fix a bug in libblkid so it correctly detects whether the ext4 and
2280 ext4dev filesystems are available, so that the ext4dev->ext4
2281 fallback code works correctly.
2286 Fix a parallel build problem by making sure util/subst is built before
2287 trying to build the lib/et directory. (Addresses Sourceforge Bug:
2290 Updated "make depend" information for crc16.o
2293 E2fsprogs 1.41.2 (October 2, 2008)
2294 ==================================
2296 Fix e2fsck's automatic blocksize detection. This fixes a regression
2297 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
2298 specifies a block number using the -b option if the blocksize option
2299 isn't also specified using -B. Unfortunately, users very commonly
2300 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
2301 superblock; in fack e2fsck will often suggest this kind of command
2304 Enhance the debugfs's "ncheck" command so it will print all of the
2305 pathnames for the specified inodes. (Previously, in some cases ncheck
2306 might not print a pathname for an inode at all if some of the other
2307 inodes had multiple hard links.)
2309 Enhance debugfs's "hash" command so the hash seed can be specified via
2310 a command-line option. In addition, allow the hash algorithm to be
2311 specified by name instead of just by number.
2313 Fix e2fsck so that we don't accidentally print the translation file's
2314 header when asking the user a custom question so there is no prompt
2315 defined for a particular problem record. For example, the question
2316 "Run journal anyway" will get the PO header tacked on because e2fsck
2317 erroneously passed the null string to _(). (Addresses Launchpad Bug:

2358 removes error tables in multiple threads. Unfortunately SuSE's

2398 E2fsprogs 1.41.1 (September 1, 2008)
2399 ====================================
2401 Many people are forgetting to update their mke2fs.conf file, and this
2402 causes ext3, ext4, and ext4dev filesystems won't get created with the
2403 proper features enabled. We address this in two ways. First, mke2fs
2404 will issue a warning if there is not definition for an ext3, ext4, or
2405 ext4dev filesystem and the user is trying to create such a filesystem
2406 type. Secondly, when installing from a source build, "make install"
2407 will provide basic configuration file handling for /etc/mke2fs.conf.
2408 If it exists, and does not mention ext4dev, it will be moved aside to
2409 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
2410 be installed. If the existing /etc/mke2fs.conf file does mention
2411 ext4dev, then "make install" will install official mke2fs.conf file as
2412 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
2413 they should look to see if any changes need to be merged.
2415 The mke2fs program will now create the journal in the middle of the
2416 filesystem, since this minimizes seek times on average for fsync-heavy
2417 workloads. In addition, mke2fs will now create journals using extents
2418 for filesystems that support them. This results in a more efficient
2419 encoding for the journal since it eliminates the need for using
2422 The mke2fs program will avoid allocating an extra block to the
2423 journal. (Addresses Sourceforge Bug: #1483791)
2425 Mke2fs will correctly enforce the prohibition against features
2426 (specifically read-only features) in revision 0 filesystems. (Thanks
2427 to Benno Schulenberg for noticing this problem.)
2429 Mke2fs previously would occasionaly create some slightly non-optimally
2430 placed inode tables; this bug has been fixed.
2432 The mke2fs and tune2fs programs now print the correct usage message
2433 describing the maximum journal size. (Addresses Debian Bug: #491620)
2435 Add support for setting the default hash algorithm used in b-tree
2436 directories in tune2fs (from a command-line option) or mke2fs (via
2437 mke2fs.conf). In addition, change the default hash algorithm to
2438 half_md4, since it is faster and better.
2440 The blkid library will now recognize MacOS hfsx filesystems, and
2441 correctly extract the label and uuid for hfs, hfsx, and hfsplus
2442 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
2444 The blkid library has improved detection of JFS and HPFS filesystems.
2445 (Addresses Launchpad Bug: #255255)
2447 The blkid library is now much more efficiently handling devicemapper
2448 devices, mainly by no longer using the devicemapper library. This can
2449 speed up access for systems with a large number of device mapper
2452 Blkid had a number of cache validation bugs in libblkid that have been
2453 fixed. (Addresses Debian Bug: #493216)
2455 Resize2fs will now properly close out the "updating inode references"
2456 progress bar so there is a newline printed before printing the final
2457 "resize is successful" message.
2459 Resize2fs will now correctly handle filesystems with extents and/o
2460 uninitialized block groups correctly when file/directory blocks need
2461 to relocated (i.e., when shrinking a filesystem or if the resize_inode
2462 is not present). To support this, the ext2fs library now supports
2463 initializing inode and block bitmaps that are not yet initialized when
2464 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
2465 addition, e2fs_block_iterate2() can now support changing the location
2466 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
2467 been optimized to avoid creating unnecessary new extents when updating
2468 the location of blocks in the extent tree. This will also help out
2469 e2fsck's recovery of obscurely corrupted filesystems with extents,
2470 when blocks are claimed by multiple inodes.
2472 Add support for on-line resizing ext4 filesystem with the flex_bg
2473 filesystem feature. The method for doing so is not optimal, but to do
2474 a better job will require kernel support.
2476 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
2477 debugfs programs to not be able to read e2image files; the signed
2478 vs. unsigned bug in the code which read bitmaps from the e2image has
2479 been fixed. (Addresses Debian Bug: #495830)
2481 Resize2fs is now correctly managing the directory in-use counts when
2482 shrinking filesystems and directory inodes needed to be moved from one
2483 block group to another. This bug has been around since e2fsprogs
2484 1.26, and is largely harmless, but does cause a filesystem corruption
2485 which will be flagged by e2fsck after the filesystem has been shrunk.
2487 E2fsck will no longer issue spurious complaints about the inode size
2488 caused by very large extent-based files, and by blocks reallocated
2489 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
2490 Kernel Bugzilla: #11341)
2492 Mke2fs will now set the creation timestamp on the lost+found directory
2493 and the root directory. (More generally, all new inodes created using
2494 the ext2fs library will correctly set the creation timestamp.)
2496 E2fsck now correctly calculates ind/dind/tind statistics in the
2497 presence of extent-based files. In addition, "e2fsck -v" will report
2498 statistics of the depth of extent trees in the filesystem. E2fsck can
2499 also give an inode fragmentation report using "e2fsck -E fragcheck"
2500 which can be useful when debugging the kernel block allocation
2503 Fix support for empty directory blocks in ext4 filesystems with 64k
2504 blocksize filesystems.
2506 E2fsck will now print the depth of corrupt htree directories.
2508 Debugfs's htree command now correctly understands extent-based
2509 directories. It will also print out the minor hash as well as the
2512 Debugfs has a new command which will print the supported features of
2513 e2fsprogs, to enable scripts to know whether the installed version of
2514 e2fsprogs can support a specific feature.
2516 Debugfs will now write files using extents for filesystems that
2519 The error message printed by "tune2fs -I" if the inode size was too
2520 small was rather confusing, so it has been improved. Also, we won't
2521 try to create an undo log until we know that command-line-specified
2522 parameters such as "tune2fs -I <inode size>" are valid.
2524 Given some filesystems found "in the wild" that had non-zero block
2525 group checksums even though the uninit_bg/gdt_sum feature was not
2526 enabled, e2fsck would issue spurious error messages. Teach
2527 ext2fs_group_desc_csum_verify() to ignore the block group checksum
2528 entirely if the feature flag is not set. (Addresses Debian Bug:
2531 The blkid program will now print out a user-friendly listing of all of
2532 the block devices in the system and what they contain when given the
2533 -L option. (Addresses Debian Bug: #490527)
2535 The filefrag program now has a more accurate calculation for the
2536 number of ideal extents. (Addresses Debian Bug: #458306)
2538 The test I/O manager is now enabled by default, but its overhead is
2539 only incurred when it would be enabled via the TEST_IO_FLAGS or
2540 TEST_IO_BLOCK environment variables.
2542 Typographical errors in various program strings and usage messages
2543 have been fixed; most of these were pointed out by the e2fsprogs
2544 message catalog translators. (Thanks, translators!)
2546 Update and clarified various man pages, as well as some typographical
2547 errors in the libext2fs texinfo file.
2549 Fixed various Debian packaging issues --- see debian/changelog for
2552 Add Indonesian and update French, Polish, Dutch, German, Sweedish,
2553 Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
2559 Fix portability problem with the badblocks group; for systems that
2560 don't have nanosleep(), try using usleep() instead.
2562 The "make check" target in the e2fsck directory now sets
2563 LD_LIBRARY_PATH before running the various e2fsck internal library
2566 The crc32 regression test in the e2fsck library is now portable to
2567 greater varienty of environments, including big-endian systems and
2568 when cross-building e2fsprogs for embedded systems. (Addresses
2569 Sourceforge Bug: #2019287)
2571 The ext2fs_extent_set_bmap() had some bugs when setting the first
2572 block in a file, or when replacing a single block extent. Those cases
2573 fortunately were came up relatively rarely when e2fsck was checking
2574 files, but caused some problems when resize2fs was shrinking
2577 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
2580 Various ext2fs library functions --- ext2fs_block_iterate2(),
2581 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
2582 allocated memory to avoid memory leaks in all of their error return
2585 Ext2ed was failing to build because masix support had been removed in
2586 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
2588 The configure script now respects the LDFLAGS environment variable if
2589 it is set when configure is called. (Addresses Sourceforge Feature
2592 Libuuid is now more portable to the Windows platform. (Addresses
2593 Sourceforge Feature Request: #1937287)
2595 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2596 bare echo commands so that configure flags such as --quiet work
2597 correctly. (Addresses Sourceforge Patches: #2058794)
2599 A few uses of sprintf have been removed from the ext2fs library to
2600 make life easier for bootloaders with a limited libc environment.
2601 (Addresses Sourceforge Bug: #2049120)
2603 The ext2fs_read_inode() checks the validity of the inode number passed
2604 to it earlier, to avoid doing some needless work when it would fail
2607 The ext2fs_open() checks the validity of the blocksize parameter
2608 passed to it earlier, to avoid doing some needless work when it would
2611 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2612 top-level Makefile. That automatic rule is used to better support
2613 SCCS, but it caused problems for a particular niche distribution which
2614 likes to use configure.sh files to store the configure options used to
2615 build a package. Unfortuntaely GNU make will use the configure.sh to
2616 replace the configure script, resulting in a self-inflicted fork bomb
2617 leading to an out-of-memory crash.
2619 To support old GNU C compilers don't use C99/C++ comments, but only
2620 K&R style comments, and don't try to use __builtin_expect if __GNUC__
2621 is less than 3. (__builtin_expect is only supported for gcc versions
2622 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2623 this is an optimization, we only try to use __builtin_expect for gcc 3
2626 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2627 __LITTLE_ENDIAN, which are only defined by glibc's header files and
2628 hence isn't portable.
2630 For the convenience for some distributions that need a static tune2fs,
2631 the Makefile for misc/ now has a tune2fs.static target.
2633 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2634 for extent-based files
2636 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2639 All source files no longer have any trailing white space.
2641 The io_channel_read_blk64() and io_channel_write_blk64() functions are
2642 now functions instead of C preprocessor macros to provide better
2643 forward compatibility.
2645 The e2fpsrogs translation template now expands the @x abbrevation.
2647 Various namespace leackages in libblkid, libe2p, and libext2fs have
2650 Fix a parallel build problem in e2fsprogs.
2652 E2fsprogs is now more portable to Solaris.
2653 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
2655 * Scripts do not assume that /bin/true is always in /bin
2656 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2657 * Flush stdio handles before calling setbuf(), since Solaris will
2658 discard any pending output to the stream.
2659 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2660 picky about which C compiler can beused for SUSv3 conformance.
2661 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2662 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2663 Since we need some SUSv3 functions, consistently use SUSv3 so
2664 that e2fsprogs will build on Solaris using c99.
2665 * Solaris C99 does not support varargs C preprocessor macros
2666 * Solaris header files pollute the C namespace if in/netinet.h
2667 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2669 * Solaris ships with a pathetically ancient shell in /bin/sh so we
2670 avoid the use of various more avanced shell constructs such as $().
2672 The "make rpm" command will now take some extra configure optiosn from
2673 the build environment without needing to patch the source tree.
2675 The ext2fs_add_dir_block() function will now grow the dblist more
2676 aggressively as an optimization to avoid copying the array too often.
2678 The e2fsck_write_bitmaps() will write the block and inode bitmaps
2679 together instead of in two passes.
2682 E2fsprogs 1.41 (July 10, 2008)
2683 ==============================
2685 Add support for ext4 filesystem features, in particular extents,
2686 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
2687 support for checking journal checksums. Debugfs will print new
2688 superblock and inode fields that were defined for ext4. For example,
2689 the nanosecond and i_version fields of an inode, and the
2690 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2691 Note: Resize2fs doesn't currently support the combination of flex_bg
2692 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
2694 Tune2fs can support migrating a filesystem from using 128 byte inodes
2695 to 256 byte inodes, so it can take advantage of the full features of
2698 Add support for "undo" support. E2fsck and mke2fs can optionally
2699 record an undo log which can replayed by the program e2undo.
2701 E2fsck could damage a filesystem by trying to relocate inode tables
2702 due to corrupted block group descriptors, where the attempted inode
2703 table relocation would do far more harm than good. E2fsck has been
2704 fixed to detect this these sorts of corrupted block group descriptors
2705 much earlier in e2fsck processing, so it can try to use the backup
2706 superblock and block group descriptors first. This should be a much
2707 better strategy for recovering these types of corrupted filesystems.
2708 (Addresses Sourceforge Bug: #1840291)
2710 E2fsck will display a more understandable message when the last check
2711 field in the superblock is in the future. (Addresses Debian Bug:
2714 E2fsck now performs more extensive and careful checks of extended
2715 attributes stored in the inode.
2717 Enhance mke2fs to print a more explanatory error message when
2718 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
2721 Fix mke2fs to use a default block size of 4k when formatting an
2722 external journal device. This is done by using a fixed filesystem
2723 type list that consists only of the single filesystem type "journal"
2724 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
2725 Debian Bug: #488663)
2727 Speed up how mke2fs writes the journal data blocks by writing the disk
2728 blocks in larger chunks.
2730 Fix blkid handling of stale devices. Fix a bug which could cause a
2731 core dump while garbage collecting the blkid cache, and assure that
2732 blkid_find_dev_with_tag() never returns a non-existent device. Also,
2733 if a filesystem is found at a new /dev location, eliminate any
2734 duplicate stale entries which can not be verified.
2735 (Addresses Debian Bugs: #487758, #487783)
2737 Add more paranoid checks for LVM volumes and swap partitions in
2738 blkid's probe function, to reduce the chances of false positives.
2740 The mke2fs program now has a much more sophisticated system for
2741 controlling configuration parameters of a newly created filesystem
2742 based on a split filesystem and usage type system. The -t option to
2743 mke2fs was a deprecated alias to -c; it now specifies a filesystem
2744 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2745 separated usage list. The filesystem type information and type
2746 information is used to extract configuration parameters from the
2747 /etc/mke2fs.conf file.
2749 The mke2fs program will no longer complain and request the -f option
2750 when the user tries to create a filesystem with greater than 2**31
2753 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2754 adjust the mke2fs.conf file so filesystems for the Hurd are created
2755 with a blocksize of 4096 and inode size of 128, which is all it knows
2756 how to handle. (Addresses Debian Bug: #471977)
2758 Mke2fs will always make sure that lost+found always has at least 2
2759 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2761 Resize2fs will now print the minimum needed filesystem size if given
2762 the -P option, and will resize the filesystem to the smallest possible
2763 size if given the -M option.
2765 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2766 blocks are consumed during an off-line resize.
2768 The "ls" command in debugfs now supports the -p option, which causes
2769 it to quote the filenames so that spaces or tabs in directory entries
2770 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
2771 Sourceforge Feature Request: #1201667)
2773 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
2776 The chattr program will return a non-zero exit code in case of
2777 failures, and error messages can be suppressed with the -f option.
2778 (Addresses Red Hat Bugzilla: #180596)
2780 Fix a bug in badblocks which caused it to overrun an array and likely
2781 crash if more than 8 test patterns are specified using the -t option.
2782 (Addresses Debian Bug: #487298)
2784 Add support to badblocks to limit how quickly it reads from the disk
2785 drive (so it can be used for background scrubbing), and so it will
2786 abort after finding a given number of errors.
2788 Remove support for the legacy big-endian filesystem format which only
2789 existed on extremely long-dead PowerPC kernels almost a decade ago.
2791 Remove MASIX support from e2fsprogs.
2793 Add I/O statistics reporting to e2fsck.
2795 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
2798 Fixed various Debian packaging issues --- see debian/changelog for
2799 details. (Addresses Debian Bugs: #487443, #487675, #490003)

2820 Clean up the badblocks group so to make it more portable and robust.
2822 Avoid using predictable filenames in /tmp in blkid's regression test
2823 suite. Also remove bashism's in the regression test script.
2825 If the configure script is given --with-diet-libc, don't use thread
2826 local storage, since diet libc doesn't support TLS. (Addresses
2827 Sourceforge Bug: #2000654)
2829 Fix the blkid regression test suite to tolerate older versions of
2830 mkswap that don't support the -U option.
2832 A few library routines have been converted to support 64-bit block
2833 numbers; in particular, the I/O manager functions, the test_io,
2834 inode_io, and unix_io managers have all be converted to support 64-bit
2837 Debugfs can now be extended for use by test programs. See
2838 lib/ext2fs/extents.c for an example for how it can be used. The test
2839 program links against the debugfs object files, and provides
2840 additional commands by defining an auxiliary libss command table.
2842 The lazy_bg filesystem feature, which was only used by developer's
2843 testing, has been removed since it has been largely supplanted by
2844 uninit_bg. This also simplifies the code.
2847 E2fsprogs 1.40.11 (June 17, 2008)
2848 =================================
2850 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
2851 percentage of reserved blocks. (Addresses Debian Bug: #452639)
2853 Updated Spanish and Catalan translations.
2855 Fixed various Debian packaging issues --- see debian/changelog for
2856 details. (Addresses Debian Bugs: #483962, #483023)
2858 Add detection for ZFS volumes to the libblkid library.
2860 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2861 (Addresses Debian Bug: #486463)
2866 Fix marginal C code in probe_lvm2() function to the blkid library more
2867 portable for older compilers.
2869 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
2871 Fix ext2fs_swap{16,32,64} functions so they can be used by external
2872 applications on big-endian machines. (Addresses Debian Bug: #484879)
2875 E2fsprogs 1.40.10 (May 21, 2008)
2876 ================================
2878 When deciding whether or not to revalidate a blkid cache entry, if the
2879 device's mtime is newer than the last time the cached entry was
2880 validated, force a revalidation.
2882 Fix a potential data corruption bug in e2fsck in the journal replay.
2883 The chances of this is happening is extremely remote, especially the
2884 default data=ordered or data=writeback modes. However, if a block
2885 which has been journalled starts with the first four bytes 0xc03b3998,
2886 when e2fsck replays the journal, those four bytes will be replaced
2887 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
2888 metadata to begin with those fatal 4 byte sequence, and unless
2889 data=ordered mode is in use, data blocks are never journaled.
2891 Updated German, Dutch, Sweedish, and Vietnamese translations.
2896 Fixed various Debian packaging issues --- see debian/changelog for
2899 Remove default sizes of types when cross compiling, since autoconf
2900 2.50 can figure this out automatically now.
2903 E2fsprogs 1.40.9 (April 27, 2008)
2904 =================================
2906 SuSE's security team audited uuidd and came up with a few minor
2907 issues. None of them are serious given that uuidd runs setuid as a
2908 unprivileged user which has no special access other than libuuid
2909 directory, but it's good to get them fixed.
2911 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
2912 work correctly with in-inode extended attributes.
2914 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
2917 Debugfs will avoid using a pager if the standard output is not a tty.
2919 Fix debugfs and tune2fs to correctly handle daylight savings time when
2920 parsing a time string.
2922 Fixed spelling mistakes, typos, and otherwise clarified man pages.

2925 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
2926 #203323, Addresses Sourceforge Bug: #1926023)
2928 Fix fsck so that progress information is sent back correctly when
2929 multiple filesystems are being check and the output of fsck is being
2930 redirected to a file descriptor. Also, include the device name (w/o
2931 spaces) in the progress information sent back via a file descriptor.

2973 E2fsprogs 1.40.8 (March 13, 2008)
2974 =================================
2976 Fixed e2image -I so it works on image files which are larger than 2GB.
2978 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
2979 the size is larger than the number of blocks found in the inode, don't
2980 try to allocate extra empty blocks at the end of the directory to make
2981 up the difference; there's no point to doing that. In addition, if
2982 the size is not a multiple of a blocksize, always fix it.
2984 E2fsck handled a pass 2 "should never happen error" by not giving
2985 enough information and then core dumping. Unfortunately, it was all
2986 too easy to trigger the "should never happen" situation if a
2987 directory's inode size was not correct. This has been fixed, but
2988 e2fsck has also been taught how to handle this situation more
2989 gracefully, by simply removing the inode hash tree information, so
2990 that it can be rebuilt again after e2fsck's pass 3. (Addresses
2991 Launchpad Bug: #129395)
2993 Resize2fs had a bug resizing large inodes with extended attributes
2994 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2995 completely on big-endian systems such as PowerPC. The bug should be
2996 completely fixed now. Yay for regression test suites. (Addresses Red
2997 Hat Bugzilla: #434893)
2999 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
3000 translations. Many thanks to Philipp Thomas from Novell for stepping
3001 up to become the new German translation maintainer! (Addresses Debian
3002 Bugs: #302512, #370247, #401092, #412882).
3004 When e2fsck is clearing a corrupt inode's HTREE directory information,
3005 make it clear that it is just clearing the HTREE information, not the
3008 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3013 Add new functions, ext2fs_dblist_get_last() and
3014 ext2fs_dblist_drop_last(), which allows the caller to examine the last
3015 directory block entry added to the list, and to drop if it necessary.
3017 Fixed a portability problem in libblkid with DJGPP.
3019 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
3020 to Philipp Thomas for pointing this out.
3022 If the info files are not built, change "make install" so it doesn't
3023 fail with an error code.
3026 E2fsprogs 1.40.7 (February 28, 2008)
3027 ====================================
3029 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
3030 depreciate the -s option, since it can result in filesystems which
3031 e2fsck can't fix easily. There are very good reasons for wanting to
3032 disable sparse_super; users who wants to turn off sparse_super can use
3033 debugfs. (Addresses Sourceforge Bug: #1840286)
3035 Add missing options to mke2fs's usage message. (Addresses Sourceforge
3038 Fix bug in resize2fs when large (greater than 128 byte) inodes are
3039 moved when a filesystem is shrunk; it was only moving the first 128
3040 bytes, so extended attributes were not getting moved. (Addresses Red
3041 Hat Bugzilla: #434893)
3043 E2fsck now prints an explicit message when the bad block inode is
3044 updated, to avoid confusion about why the filesystem was modified.
3045 (Addresses Sourceforge Bug: #756460)
3047 Allow mke2fs and tune2fs manipulate the large_file feature.
3048 Previously we just let the kernel and e2fsck do this automatically,
3049 but e2fsck will no longer automatically clear the large_file feature.
3050 It still isn't really necessary to worry about this feature flag
3051 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
3054 Suppress message about an old-style fstab if the fstab file is empty.

3058 reporting a free block more than once if there are too few free blocks
3059 in the filesystem. (Addresses Sourceforge Bug: #1096315)
3061 Change e2fsck to no longer clear the LARGE_FILES feature flag
3062 automatically, when there are no more > 2GB files in the filesystem.
3063 It's been almost a decade since there have been kernels that don't
3064 support this flag, and e2fsck clears it quietly without telling the
3065 user why the filesystem has been changed.
3067 Fix bug which could cause libblkid to seg fault if a device mapper
3068 volume disappears while it is being probed. (Addresses RedHat
3071 Inhance e2fsck's reporting of unsupported filesystem feature flags.

3074 Fix option syntax in dumpe2fs for explicit superblock and blocksize
3075 parameters. What was currently documented in the man page has been
3076 broken for some time, due to getopt() implementation changes. The
3077 option sytax has been changed to one which is can be more portable
3078 supported and which is consistent with the format for extended options
3079 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
3081 Add support to tune2fs to clear the resize_inode feature. This
3082 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)

3116 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
3117 partially filled-in filesystem object on an error, so that e2fsck can
3118 print more intelligent error messages.
3120 Add a new function e2p_edit_feature2() which allows the caller to
3121 specify which feature flags are OK to set or clear, and which returns
3122 more specific information about feature flags which are not allowed to

3186 ===================================
3188 Fix a potential overflow big in e2image if the device name is too
3191 Mke2fs will now create new filesystems with 256 byte inodes and the
3192 ext_attr feature flag by default. This allows for much better future
3193 compatibity with ext4 and speeds up extended attributes even on ext3
3196 Teach e2fsck to ignore certain "safe" filesystem features which are
3197 set automatically by the kernel. Having the kernel set features
3198 automagically behind the user's back is a bad idea, and we should try
3199 to break the kernel of this habit, especially for the newer ext4
3200 feature flags. But for now, we will try to avoid needless full checks
3201 which can annoy users who are doing fresh installs.
3203 Add support in tune2fs and mke2fs for making a filesystem as being "ok
3204 to be used with test kernel code". This will be needed for using test
3205 filesystems with the latest ext4 kernel code.
3207 Change e2fsck -fD so that it sorts non-htree directories by inode
3208 numbers instead of by name, since that optimizes performances much
3209 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
3211 If e2image fills the disk, fix it so it exits right away instead of
3212 spewing large numbers of error messages.
3213 (Addresses-Sourceforge-Feature-Request: #606508)
3215 If ftruncate64() is not available for resize2fs, let it use ftrucate()
3216 instead, but have it check to see if the size would get truncated, and
3217 skip calling ftruncate in that case.
3219 Add support for detecting HFS+ filesystems in the blkid library.
3221 Add supprt in the blkid library for ext4/ext4dev filesystems.
3223 Fix a bug in blkid where it could die on a floating point exception
3224 when presented with a corrupt reiserfs image.
3226 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
3227 such that UUID string is a fixed length.
3229 Add sample python bindings for the uuid library to the contrib
3230 directory. (Addresses-Sourceforge-Patches: #778817)

3236 Allow the debugfs 'undel' command to undelete an inode without linking
3237 it to a specific destination directory, since this might require
3238 allocating blocks that could overwrite some yet-to-be-recovered
3239 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)

3277 Improve time-based UUID generation. A new daemon uuidd, is started
3278 automatically by libuuid if necessary. This daemon is setuid to allow
3279 updates to /var/lib/libuuid, so the clock sequence number can be

3286 filesystem check is required before backing up the superblock due to
3287 changes in the feature flags. (Addresses Debian Bug: #454926)
3289 Fix fsck to only treat the '#' character as a comment at the beginning
3290 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

3330 ===================================
3332 Fix a potential security vulnerability where an untrusted filesystem
3333 can be corrupted in such a way that a program using libext2fs will
3334 allocate a buffer which is far too small. This can lead to either a
3335 crash or potentially a heap-based buffer overflow crash. No known
3336 exploits exist, but main concern is where an untrusted user who
3337 possesses privileged access in a guest Xen environment could corrupt a
3338 filesystem which is then accessed by the pygrub program, running as
3339 root in the dom0 host environment, thus allowing the untrusted user to
3340 gain privileged access in the host OS. Thanks to the McAfee AVERT
3341 Research group for reporting this issue. (Addresses CVE-2007-5497.)
3343 Fix hueristics in blkid which could cause a disk without partitions to
3344 be incorrectly skipped when a loopback device is present. (Addresses
3345 Red Hat Bugzilla #400321.)
3347 Fix e2image so that in raw mode it does not create an image file which
3348 is one byte too large.
3350 Change mke2fs's usage message so it recommends the preferred -E option
3351 instead of the deprecated -R option.
3353 Enhance the blkid library so it will recognize squashfs filesystems.
3354 (Addresses Red Hat Bugzilla #305151.)
3356 Enhance e2fsck so it will force the backup superblocks to be backed up
3357 if the filesystem is consistent and key constants have been changed
3358 (i.e., by an on-line resize) or by e2fsck in the course of its
3361 Enhance blkid's detection of FAT filesystems; so that USB disks with
3362 only a single bootable partition will not get missed.
3364 E2fsck will no longer mark a filesystem as invalid if it has time
3365 errors (i.e., if superblock mount time or last write time is in the
3366 future) and the user refuses to fix the problem.
3368 The Ubuntu init scripts don't properly set the system time correctly
3369 from hardware clock if the hardware clock is configured to tick local
3370 time instead of GMT time. Work around this as best as we can by
3371 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
3372 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
3375 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
3376 Hat Bugzilla #151533.)
3378 Fix e2fsck so that if the superblock is corrupt, but still looks
3379 vaguely like an ext2/3/4 superblock, that it automatically tries to
3380 fall back to the backup superblock, instead of failing with a hard
3383 Make the e2fsprogs program more robust so that they will not crash
3384 when opening a corrupt filesystem where s_inode_size is zero.
3386 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
3387 arguments are detected as such and the parse error is reported to the
3388 user. (Addresses Debian Bug #435381.)
3390 Change e2fsck so it will not complain if a file has blocks reallocated
3391 up to the next multiple of a system's page size.
3393 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
3394 about (valid) filesystems where the inode table extends to the last
3395 block of the block group. (Addresses Red Hat Bugzilla #214765.)
3397 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
3398 allocating inode tables for some relatively rare odd disk sizes.

3401 Add Catalan translation and update Dutch and Swedish translations
3402 from the Translation Project.
3404 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We

3423 clena up after themselves by deleting the test.img temporary file
3424 after completing the test.
3426 Fixed a corner case bug ext2fs_unlink() when trying to delete the
3427 first directory entry in a directory block and the last directory
3428 entry in the previous directory block is not in use. Fortunately
3429 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
3430 places where it is extremely unlikely to run into this corner case.
3432 Fix missing dependency which would cuase parallel builds to fail.
3433 (Addresses Sourceforge Bug #1842331.)
3435 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
3436 calling open(O_CREATE) with a missing mode parameter.

3443 are properly passed back up through the call stack.
3445 E2fsprogs 1.40.2 (July 12, 2007)
3446 ================================
3448 A recent change to e2fsck_add_dir_info() to use tdb files to check
3449 filesystems with a very large number of filesystems had a typo which
3450 caused us to resize the wrong data structure. This would cause a
3451 array overrun leading to malloc pointer corruptions and segfaults.
3452 Since we normally can very accurately predict how big the the dirinfo
3453 array needs to be, this bug only got triggered on very badly corrupted
3456 Fix a bug in e2fsck which caused it to incorrectly salvange
3457 directories when the last entry's rec_len is bogusly too big. This
3458 resulted in a nonsense filesystem corruption to be reported, and
3459 required a second run of e2fsck to fully fix up the directory.

3464 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
3468 E2fsprogs 1.40.1 (July 7, 2007)
3469 ===============================
3471 Fix bug which could cause libblkid to loop forever. When revalidating
3472 a partition where there is obsolete information in /etc/blkid.tab, we
3473 end up freeing a the type tag without clearing dev->bid_type, causing
3474 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
3476 The Turkish translation has a bug in it where it has the translation
3477 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
3478 @E, recursively, forever, until the stack fills up and e2fsck core
3479 dumps. We fix this by making e2fsck stop @-expansions after a
3480 recursive depth of 10, which is far more than we need.
3481 (Addresses Sourceforge Bug: #1646081)
3483 Compile the default mke2fs.conf into mke2fs program. People are
3484 getting surprised by mke2fs creating filesystems with different
3485 defaults than earlier versions of mke2fs if mke2fs.conf is not
3486 present. So we now create a built in version of mke2fs.conf file
3487 which is used by mke2fs if the /etc/mke2fs.conf is not present.
3488 (Addresses SourceforgeBug: #1745818)
3490 Improve the config/parse_types.sh helper script. Fix a potential
3491 security problem if e2fsprogs is built as root (as Gentoo does!). In
3492 addition fix the script and how it is called from the configure script
3493 so that it does the right thing when cross-compiling. (Fixes Gentoo
3496 Update Vietnamese, French, and Dutch PO files from the Translation
3497 Project. Also created a new e2fsprogs.pot file for translator.
3499 Fix bogus strip permission errors when building under Debian. When
3500 building the e2fsprogs dpkg's, the dh_strip command emits a large
3501 number of error messages caused by the permissions not being right.
3502 So run dh_fixperms before running dh_strip.
3507 Add new function: profile_set_default(). This function sets the value
3508 of the pseudo file "<default>". If the file "<default>" had
3509 previously been passed to profile_init(), then def_string parameter
3510 will be parsed and used as the profile information for the "<default>"

3514 mk_cmds script which is generating the error. (Obviates Gentoo patch:
3515 e2fsprogs-1.32-mk_cmds-cosmetic.patch)

3518 priority" environment variable that overrides all others, where as
3519 LANG is the lowest priorty environment variable. If LC_ALL is set, it
3520 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3521 the all the rest are set. This will assure that the locale when
3522 running the test suites is the "C" locale. (Obviates Gentoo patch:

3529 Fix divide by zero error in blkid's NTFS probing logic.
3531 Add new blkid -g option which causes the blkid cache to be garbage
3534 Fix a bug in libblkid which could cause the internal field bid_type to
3535 become corrupted. Fortunately bid_type isn't used much, and bid_label
3536 and bid_uuid is only used by debugging code, so the impact of this bug
3539 Mke2fs will now store the RAID stride value when a filesystem is
3540 created with a requested RAID stride, and then use it automatically in
3543 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3544 isn't too big. In some cases Lustre users have tried specifying an
3545 inode size of 4096 bytes, while keeping an inode ratio of one inode
3548 Improve sanity check in e2fsck's algorithm for finding a backup
3549 superblock, so that it won't accidentally find a superblock that was
3550 located in the journal, and then later reject it as being not a valid
3553 Fix e2fsck get_size logic so that it will work with the Linux floppy
3554 driver. The Linux floppy driver is a bit different from the other
3555 block device drivers, in that if the device has been opened with
3556 O_EXCL, it disallows another open(), even if the second open() does
3557 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
3559 Fix error checking of badblock's last-block and start-block arguments.

3563 recovering a journal until the master superblock has been confirmed as

3567 that a partition contains an NTFS filesystem, and fetch the UUID and
3568 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:

3578 Fix e2fsck so that it updates the journal inode if it is corrupted and
3579 the backup journal information from the superblock was successfully
3580 used to recover the filesystem.
3582 Fix e2fsck so that it checks all of the blocks in the journal inode
3583 for validity. The original code only checked the direct blocks to
3584 make sure the journal inode was sane. Unfortunately, if some or all
3585 of the indirect or doubly indirect blocks were corrupted, this would

3590 Add extra sanity checks for extended attributes in the case where the
3591 size is zero but the offset is very large.
3593 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3594 and ext2fs_get_next_inode_full().
3596 Clarify the copyright licenses used by the various libraries in
3597 the top-level COPYING file (Red Hat Bugzilla: 166058)
3599 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3601 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3603 Remove check in e2fsck which requires EA's in inodes to be sorted;
3604 they don't need to be sorted, and e2fsck was previously wrongly
3605 clearing unsorted EA's stored in the inode structure.
3607 Allow mke2fs or tune2fs to create a substantially larger journal (up
3608 to 10,240,000 blocks).
3610 Fix MD superblock detection, and make sure the correct UUID is
3611 reported from the MD superblock.
3613 Fix a signed vs. unsigned bug in debugfs.
3615 Enhance debugfs's date parser so that it accepts integer values.
3617 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3618 file with multiply claimed blocks is hard linked. or not at all if the
3619 root directory contains shared blocks
3621 Enhance debugfs so it can modify the block group descriptors using the
3622 command set_block_group_descriptor.
3624 Improve e2fsck's reporting of I/O errors so it's clearer what it was
3625 trying to do when an error happens
3627 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3628 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:

3645 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3646 field on the first pass.
3648 Fix e2fsck to set the file type of the '..' entry when connecting
3649 a directory to lost+found. (Addresses Lustre Bug: #11645)
3651 Enhance e2fsck to recover directories whose modes field were corrupted
3652 to look like special files. This is probably only useful in
3653 artificial test cases, but it will be useful if we ever do the "inodes
3654 in directory" idea for ext4.
3656 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
3659 Fix resize2fs parsing of size parameter (in sector units). This was
3660 actually a bug in libe2p's parse_num_blocks() function. When handling
3661 the 's' suffix, it was ignoring the blocksize information passed in
3662 from the caller and always interpreting the number in terms of a 1k
3663 blocksize. (Addresses Debian Bug: #408298)
3665 There was a floating point precision error which could cause e2fsck to
3666 loop forever on really big filesystems with a large inode count.

3669 Fix memory leak in ext2fs_write_new_inode()
3671 Add support for using a scratch files directory to reduce e2fsck's
3672 memory utilization on really big filesystems. This uses the TDB
3673 library. See the [scratch_files] section of the e2fsck.conf man page
3676 Fixed type-punning bug which caused dumpe2fs to crash on the Arm

3682 Allow debugfs and dumpe2fs to support fs features under development.
3684 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3685 ext2fs_open() , which allows application to open filesystes with features
3686 which are currently only partially supported by e2fsprogs.
3688 Allow unix_io to support offsets greater than 2G (Addresses
3689 SourceForge Bug: #1547922)
3691 Fixed overflow and signed/unsigned problems caused by the number of
3692 blocks or inodes exceeding 2**31 or being close to 2**32-1.
3694 Add support for unsigned directory hash calculations with hints in the
3695 superblock to fix cross-architectural portability for htree
3696 directories with filenames where the high 8th bit is set. (Addresses

3700 filesystem or the kernel does not support on-line resizing.

3703 Require mke2fs -F -F for really dangerous operations, since -F is
3704 needed for less dangerous operations such as creating filesystems
3705 images in regular files, or creating filesystems on whole block
3706 devices. These relatively innocuous usages should NOT be confused
3707 with running mke2fs on an apparently-mounted or in-use filesystem.
3709 Allow the default inode size to be specified into the mke2fs.conf
3712 Make the smallest default journal size is big enough so that on-line
3713 resizing should always work.

3721 Fix debugfs display bug us that bytes that have the high bit set are
3722 displayed as "ec" instead of "ffffffec".
3724 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3726 Device mapper scanning wasn't working in the blkid library because the
3727 pathnames had an extra "/dev" when they were being probed.
3729 Add GFS/GFS2 support to the blkid library.
3731 Fix blkid support of empty FAT filesystem labels.
3733 Avoid recursing forever (or for a long time) when the blkid library
3734 searches for a device and there are symlinks to directories in /dev.

3744 Improve the (non-installed, for experts only) findsuper program by
3745 printing the uuid and label from the superblocks, as well as the

3747 the superblock. Omit by default printing superblocks that are likely
3748 found in located in an ext3 journal unless an explicit -j option is
3751 Updated Spanish, French and Dutch translations and added Catalan
3752 translation. (Addresses Debian bug: #411562)
3754 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3755 determining a partition's size, since binary searching to determine
3756 the device doesn't work on FreeBSD.
3758 Documentation about UUID's is available in enough places, and it's
3759 awkward to deal with debian-legal's insanities. So I'm caving in the
3760 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3761 don't have do the dfsg tarball. Also remove the rule that only tried
3762 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3763 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
3765 Fix the info-dir line so that the menu name does not contain a .info
3766 prefix. First of all, it's ugly, secondly, it causes the install-info

3786 (Addresses Sourceforge Bug: #1565561)
3788 Remove unused variables and other lint/gcc -Wall cleanups
3790 Add check to ext2fs_get_device_size() so it will return EFBIG for for
3791 filesystems contained in regular files where the filesystem image size
3792 is returned by stat64().
3794 Set local environment variables to C so mk_cmds and compile_et always
3795 work. (Addresses SourceForge Bug: #1532177)
3797 Added the 64-bit byte swapping function ext2fs_swab64().
3799 Added two new helper functions to prevent 2**31/2**32-1 overflow
3800 problems: ext2fs_div_ceil() and e2p_percent().
3802 Create new ext2fs library inline functions ext2fs_group_first_block()
3803 and ext2fs_group_last_block() in order to calculate the starting and
3804 ending blocks in a block group.
3806 Create the generated files read-only to remind developers not to edit them.
3808 Add support for autoconf 2.60 (with backwards compatibility for older
3809 versions of autoconf).
3811 Added an "make rpm" target to top-level Makefile
3813 Added various FreeBSD portability fixes.
3815 Exclude mercurial files from the RPM build tree to speed up copy/build.
3817 Use root_sysconfdir to define the locations of mke2fs.conf and
3818 e2fsck.conf instead of using a hard-coded /etc pathname.
3820 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3822 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3824 If diff -u is supported, use it to report test failures.
3826 Updates/improvements to RPM spec file
3828 Add on-disk format definitions for the following new features:
3829 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3830 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3831 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3833 Add a new make target "checked-failed" in the tests directory which
3834 reruns any failed tests
3836 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3838 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3839 pointer dereferences, memory leaks, etc. None were security-criticial
3842 Fix up usage and decrement error messages in the test_icount program
3844 Add debugging code to the com_err library; if the environment variable
3845 COMERR_DEBUG is set to 1, print out debugging messages as error tables
3846 are added and removed from the com_err library. If the
3847 COMERR_DEBUG_FILE environment variable is set (and the process is not
3848 setuid) the debugging messages may be redirected to a file.
3850 Change all of the e2fsprogs programs to use the newer add_error_table()
3851 and remove_error_table() interfaces instead of the much older
3852 initialize_*_error_table() function.
3854 Add TDB support into the ext2fs library. This allows us to have a
3855 guaranteed library we can count on always being present so we can
3856 store data in an on-disk database.
3858 Add support for using TDB to store the icount data, so we don't run out
3859 of memory when checking really large filesystems.
3861 Change the regression test suite so that it skips empty test directories.
3863 Define the l_i_iversion field in ext2_inode. The l_i_version field is
3864 now defined from the old l_i_reserved1 field in the ext2 inode. This
3865 field will be used to store high 32 bits of the 64-bit inode version
3868 Add Makefile production rule for e2fsprogs.spec in case it gets
3871 Add new function profile_get_uint() to allow for a clean way to fetch
3872 unsigned integers from the context.
3874 Add test to make sure the ext2 superblock structure is 1024 bytes.
3876 Fix typo in name of f_dup4 regression test
3878 Add new function blkid_gc_cache() which performs a garbage collection
3879 pass on the /etc/blkid.tab file.
3881 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
3882 general, only e2fsck (after the filesystem is clean), tune2fs, and
3883 resize2fs should change the backup superblocks by default. Most
3884 callers of ext2fs_open() should not be touching any superblock fields
3885 which require the backups to be touched.
3887 Add new function to libext2fs, ext2fs_default_journal_size(), which
3888 returns the default journal size.
3891 E2fsprogs 1.39 (May 29, 2006)
3892 =============================
3894 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3895 between 2**31 and 2**32 blocks.
3897 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3898 configure the filesystem features, blocksize, and inode_ratio for
3899 different filesystem types.
3901 Mke2fs will now create filesystems hash trees and on-line resizing
3902 enabled by default, based on the new /etc/mke2fs.conf file.
3904 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3905 filesystem device node in exclusive mode to prevent accidents by
3906 system administrators. In the case of resize2fs and mke2fs, it will
3907 only use exclusive mode if the filesystem is not mounted.
3909 Fixed a bug in mke2fs which caused it to to fail when creating the
3910 resize inode for large filesystems. (Addresses Debian Bug #346580)
3912 When allocating space for the RAID filesystems with the stride
3913 parameter, mke2fs will now place each portion of the group's inode
3914 table right up after the superblock (if present) in order to minimize
3915 fragmentation of the freespace.
3917 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3918 efficiently by writing the inode and block bitmaps in one pass, thus
3919 reducing the number of disk seeks required.
3921 Add support for on-line resizing to resize2fs.
3923 Fix blkid library so that logic to determine whether or not a device's
3924 cached information in /etc/blkid.tab needs to be verified or not
3925 doesn't get confused by a system clock which is insane (for example,
3926 if the battery is dead on a Macintosh running PPC Linux. (Addresses
3927 Red Hat Bug: #182188)
3929 The blkid library will now store the UUID of the external journal used
3930 by ext3 filesystems, so that in the future, the userspace mount binary
3931 can use this to find the location of the external journal and pass
3932 this information to the kernel.
3934 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3935 control how various options should be handled. See the e2fsck.conf
3936 man page for more details. (Addresses Debian Bug: #150295)
3938 E2fsck now prints an explanatory message when delaying a filesystem
3939 check when the system is running on battery. (Addresses Debian Bug:
3942 E2fsck will detect if the superblock's last mount field or last write
3943 field is in the future, and offer to fix if so. (Addresses Debian Bug
3944 #327580) These problems will be fixed automatically in preen mode
3945 since Debian's boot sequence bogusly doesn't set the time correctly
3946 until potentially very late in the bootup process, and this can cause
3947 false positives which will cause users' systems to fail to boot.
3948 (Addresses Debian Bugs #343662 and #343645)
3950 E2fsck now checks to see if the superblock hint for the location of
3951 the external journal is incorrect, and if so, offer to update it.
3952 (Addresses Debian Bug: #355644)
3954 Fix e2fsck from segfaulting on disconnected inodes that contain one or
3955 more extended attributes. (Addresses Debian Bug: #316736, #318463)
3957 E2fsck will stop and print a warning if the user tries running a
3958 read/write badblocks test on a read-only mounted root filesystem.
3960 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
3961 C. Thompson for pointing these out; they were originally found using
3964 When resizing a file containing a filesystem, resize2fs will expand or
3965 truncate a file as necessary. (Addresses Debian Bug: #271607)
3967 Resize2fs will now automatically determine the RAID stride parameter that
3968 had been used to create the filesystem, and use that for newly created
3969 block groups. The RAID stride parameter may also be manually specified
3970 on the command line using the new -S option to resize2fs.
3972 Fix mke2fs so that it correctly creates external journals on
3973 big-endian machines (such as a S/390).
3975 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3976 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
3977 Chambraud for pointing this out.)
3979 Dumpe2fs will now print the size of the journal (if present).
3981 Fix debugfs's set_inode_field command so it can properly set the frag,
3982 fsize, uid_high, gid_high, and author fields in the inode instead of
3983 silently failing, and so that setting the i_size actually sets i_size
3986 Add a new debugfs command, set_current_time, which sets fs->now so
3987 that regression test suites can repeatedly modify the filesystem's
3990 Fix a bug in debugfs's icheck which would incorrectly report the owner
3991 of an extended attribute block.
3993 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3994 print a usage message when an illegal option character is given.
3996 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3997 so it won't core dump. (Addresses SourceForge bug #1424311)
3999 Fix mklost+found so that it creates a full-sized directory on
4000 filesystems with larger block sizes.
4002 Fix a file descriptor leak in blkid library.
4004 Fix a display bug in "badblocks -sv" so that the done message properly
4005 clears the block number at the end of the test. (Addresses Debian Bug

4016 that the "best" (i.e., leaf) device is probed by the blkid library.
4018 Fix the blkid library so that it notices when an ext2 filesystem is
4021 Improve the blkid's library VFAT/FAT detection; it now understands
4022 labels stored in the root directory, and is more paranoid about
4023 checking the FAT superblock values.
4025 Fixed a fd leak in the uuid library which was causing problems for the
4026 LVM tools. (Addresses Debian Bug: #345832)
4028 Add support for the reiser4 and software suspend partitions to the
4029 blkid library. Also add support for extract the label from iso9660
4032 Fix a compile_et bug which miscount the number of error messages if
4033 continuations are used in the .et file.
4035 Add extra sanity checks to protect users from unusual cirucmstances
4036 where /etc/mtab may not be sane, by checking to see if the device is
4037 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug

4067 GNU make (i.e., 3.81).
4069 Add valgrind support to the regression test suites, and eliminate
4070 false positives from valgrind.
4072 Add a regression test suite for the blkid library.
4074 Fix a fencepost error in resize2fs caught by valgrind.
4076 Fix compiler warnings about missing memcpy prototypes.
4078 We no longer have the sparc assembly code in the header file any more,
4079 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
4080 break compiles on the sparc architectures when using gcc.
4082 In the libext2fs library, add the new field fs->now which if non-zero
4083 is used instead of the system time when setting various filesystem
4084 fields (last modified time, last write time, etc.)
4086 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
4087 ext2fs.h which is needed since the inline functions use memcpy().
4088 (Addresses Sourceforge Bug #1251062)
4090 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
4091 the build system when building files in the util directory which are
4092 needed during the build process. This avoids potential problems when
4093 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
4094 are not recognized as valid by the host compiler. (Addresses
4095 Sourceforge Bug #1261547)
4097 Clean up the blkid library by making the superblock and generic i/o
4098 functions to be more generic. Clean up interface to the probe
4099 function, and fix memory leak. Finallly, remove an unneeded reference
4100 to probe.h in the lib/blkid/resolve.c
4102 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
4103 of invalid block #'s.
4105 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
4106 indicate that the the function read/writes the memory location.
4108 Fix various gcc -Wall complaints.
4110 Add a dependency to make sure that the subdirectories are created
4111 before creating all of the object files, in order to address parallel
4112 build problem in the library Makefiles. (Addresses Sourceforge Bug:
4115 Add $(LDFLAGS) to the command line argument when generating an ELF or
4116 Solaris shared library, to allow cross-compile and other builds that
4117 might need to specify -L paths to needed libraries. (Addresses
4118 Sourceforge Bug #1261549)
4120 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
4121 intended for testing purposes. It allows an ext2/ext3 developer to
4122 create very large filesystems using sparse files where most of the
4123 block groups are not initialized and so do not require much disk
4124 space. Eventually it could be used as a way of speeding up mke2fs and
4125 e2fsck for large filesystem, but that would be best done by adding an
4126 RO_COMPAT extension to the filesystem to allow the inode table to be
4127 lazily initialized on a per-block basis, instead of being entirely
4128 initialized or entirely unused on a per-blockgroup basis.
4130 Fix backwards compatibility so e2fsprogs will better compile on Linux
4133 Make test scripts more robust against locale-related environment variables
4135 Fix type warning problem with sizeof() in ext2fs_open2().
4137 Fix type warning problem with time_t in debugfs.
4140 E2fsprogs 1.38 (June 30, 2005)
4141 ==============================
4143 Fix blkid's test programs (built with "make check") compile correctly
4144 even without "configure --enable-blkid-debug".
4146 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
4147 type aliasing rules on newer gcc compilers. (Addresses Red Hat
4150 Fix com_err library to make it more compatible with recent changes
4151 made to the com_err library in MIT Kerberos V5 version 1.4.
4152 (Addresses Sourcefroge Bug #1150146)
4154 General cleanup of messages printed by e2fsprogs programs for grammar,
4155 consistency, and to make life easier for translators. Fixed a few
4156 strings containing English that had not been marked as needing
4157 translations. Removed strings that do not need to be translated, to
4158 make life easier for translators.
4160 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
4161 test to see if a device appears to be in use instead of just relying
4162 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
4164 Fix portability problem in the filefrag program affecting platforms
4165 where the size of an integer is smaller than the size of a long.
4166 (Addresses Debian Bug #309655)
4168 Mke2fs will now use a larger journal by default for filesystems
4169 greater than 4GB. (128 MB instead of 32MB).
4171 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
4172 unless forced. This is to avoid signed vs. unsigned kernel bugs in
4173 block numbers that still need to be fixed.
4175 The blkid program has a new option which will more efficiently search
4176 for device when it is known (or expected) that only one matching
4177 device will be found in the system, such as when doing a lookup by
4180 Debian's e2fsprogs-specific initrd fragment will avoid including
4181 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
4182 and LD_LIBRARY_PATH, and filtering out libraries found in
4183 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
4185 Fixed a potential portability issue in the blkid programs for
4186 architectures where the char type is unsigned. (Addresses Sourceforge
4189 Fix a bug in filefrag so that it doesn't falsely count an extra
4190 discontinuity when the first block found is an indirect block.
4191 (Addresses Debian Bug #307607).
4193 Fix blkid's recognition of cramfs filesystems, and enhance it to be
4194 able to handle cramfs labels.
4196 Fix debugfs's stat command to not core dump when a filesystem is not
4199 Fix e2fsck's handling of error conditions caused by the resize inode
4200 claiming blocks that are also used by other inodes, a filesystem
4201 corruption which was commonly caused by a bug in Fedora Core 3's
4204 Fixed bug in filefrag which caused it to fail on non-ext2/3
4205 filesystems. (Addresses Debian Bug: #303509)
4207 If the superblock last mount time indicates that the system clock may
4208 not be accurate, then e2fsck will omit checking inodes' deletion time
4209 field for indications of a potential corrupted orphaned inode list.
4210 (Previously e2fsck only ommited these LOW_DTIME checks when the
4211 superblock's last write time looked insane.)
4213 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
4214 (Addresses Debian bug #302200)
4216 Make the blkid library more paranoid about being run from setgid
4217 programs, and to use __secure_getenv() from libc if it is available.
4219 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4220 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
4221 and Sourceforge Bug: #1189803)
4223 Updated and fixed translations.
4225 Fixed various Debian packaging issues --- see debian/changelog for
4231 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
4232 changed to take an unsigned int for the bit number. Negative bit
4233 numbers were never allowed (and didn't make any sense), so this should
4234 be a safe change. This is needed to allow safe use of block numbers
4235 greater than or equal to 2**31.
4237 The compile_et program will avoid recreating generated foo_err.c and
4238 foo_err.h files if no changes are necessary. The compile_et program
4239 will also atomically replace these files to avoid a potential parallel
4240 build race problem on SMP systems. (Addresses Sourceforge Bug:
4243 Added a new function to the blkid library, blkid_probe_all_new(),
4244 which only probes newly added disk devices, and change
4245 blkid_find_dev_with_tag() to use this function so that when a
4246 requested tag is not found, devices that were previously not checked
4247 are searched before searching all devices in the system.
4249 Added new functions to the blkid library, blkid_dev_set_search() and
4250 blkid_dev_has_tag().
4252 E2fsck's problem strings can now use @m and @n as abbrevations for
4253 "multiply-claimed" and "invalid", respectively.
4255 The e2fsprog.pot file now has an explanation of how the @-expansion
4256 and %-expansion works, and strings in e2fsck/problem.c which contain @
4257 characters now have comments in e2fsprogs.pot with the @-expansion to
4258 make life easier for translators.
4260 Fixed missing return values in the ext2fs library which could cause it
4261 to return random garbage in certain error conditions.
4263 Allow the current time to be overriden via the E2FSCK_TIME environment
4264 variable for use in regression tests.
4266 The test scrpit driver program now exits with a non-zero status if
4267 there any of its test that it ran failed.
4269 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
4272 Fixed "make check" so that it compiles correctly even when e2fsprogs'
4273 header files have not be installed in the system include directories.
4274 (Addresses Sourceforge Bug: #1180572)
4276 Fixed gcc -Wall nits.
4279 E2fsprogs 1.37 (March 21, 2005)
4280 ===============================
4282 Add support for checking the validity of Extended Attributes stored in
4285 Add support for dumping the contents of large inodes to debugfs,
4286 including the extended attributes stored in inodes.
4288 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
4289 when we create a new inode we make sure that the extra information in
4290 the inode (any extra fields in a large inode and any ea-in-inode
4291 information) is initialized correctly. This can take place when
4292 mke2fs creates the root and lost+found directory, when e2fsck creates
4293 a new root inode or a new lost+found directory, and when the user uses
4294 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
4295 create inode could inherit garbage (or old EA information) from a
4296 previously deleted inode.
4298 Fixed a bug in e2fsck so it would notice if a file with an extended
4299 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
4302 Added support to filefrag to detect files which are using the new
4303 experimental file extents format, and use the non-ext2 algorithm in
4304 that case. Fixed a bug to avoid reporting a false discontinuity if
4305 there is one or more unallocated blocks at the beginning of a file.
4307 Duplicated a check for noticing whether or not the number of blocks
4308 (given a certain blocksize) is greater than 2**32 when the
4309 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
4310 allows mke2fs to automatically use a larger blocksize when creating a
4311 filesystem on a very large device when run on systems that do not
4312 support BLKGETSIZE64.
4314 Fix the I18N build which was broken in e2fsprogs 1.36 because the
4315 build system had been switched to treat the .gmo files as shipped
4316 files (for backwards compatibility with systems that have older GNU
4317 I18N tools installed), but the gen_tarball.in script was still
4318 removing the .gmo files from the official source distribution.
4320 Fixed various Debian packaging issues --- see debian/changelog for
4321 details. (Addresses Debian Bugs ##296769, #299341)
4326 Added new functions to the e2p library which convert between a string
4327 and os_type: e2p_os2string() and e2p_string2os(), and used them to
4328 make the generated binaries more compact.
4330 Fixed a compile-time error on Darwin systems.
4332 Cleaned up the lib/ext2fs Makefile slightly.
4335 E2fsprogs 1.36 (February 4, 2005)
4336 =================================
4338 All of the patches that were applied to Fedore Core 3's
4339 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
4340 lot of bug fixes first. Users of Fedora Core 3 are strongly
4341 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
4343 Add support for filesystem with the online resizing via resize inode
4344 feature. Fixed numerous bugs from the Fedora patches. The Fedora
4345 patches also didn't bother to do any consistency checking on the
4346 resize inode, or add any tests to the regression test suite. The "-R
4347 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
4348 being listed in mke2fs's usage message. All of these shortcomings
4349 have been corrected.
4351 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
4352 program. In order to do this, the user must run the commands:
4354 debugfs -w /dev/hdXXX -R "features ^resize_inode"
4355 e2fsck -f /dev/hdXXX
4357 Optionally, the ext2prepare command can be used to re-enable online
4358 resizing after the filesystem has been fixed.
4360 The fsck program will now accept an optional filedescriptor argument
4361 to the -C option. (The Fedora version of this patch would sometimes
4362 cause fsck to ignore a parameter on fsck's command line in some rare
4365 Make sure e2fsprogs doesn't write garbage into the reserved portion of
4368 Make sure resize2fs releases the blocks belonging to the old inode
4369 table blocks when moving the inode table. (Addresses Debian Bug:
4372 Skip the r_resize_inode test if resize2fs is not compiled (due to
4373 configure --disable-resizer)
4375 E2fsck now checks the summary filesystem accounting information, and
4376 if any of the information is obviously wrong, it will force a full
4377 filesystem check. (Addresses Debian Bug #291571)
4379 Fix e2fsck to not complain when the resize_inode feature is enabled,
4380 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
4383 Fix e2fsck to note delete symlinks that contain an extended attribute
4384 after the ext_attr feature flag has been cleared. (Addresses Red Hat
4387 Add new utility program, copy_sparse.c, which is very useful
4388 for dealing with large sparse files (such as e2image files).
4390 Add support for jnl_blocks[] for debugfs's set_super_value.
4392 Fix filefrag so that it works correctly with sparse files.
4394 Filefrag -v will print first and last blocks.
4396 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
4399 Add mke2fs support so that it can support filesystems larger than 4TB
4400 automatically, by retrying with a 4k blocksize if the device size is
4401 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
4404 Change blkid to test for NTFS first because Windows sometimes doesn't
4405 clear enough of the parition to confuse the probing routines into
4406 thinking the old filesystem type is still valid. (Addresses Debian
4409 Add support for swap partition label and uuid's in the blkid library.
4411 Add support to the blkid library to recognize Oracle ASM volumes.
4413 Make blkid -t display all devices that match the specified criteria,
4414 not just the first one, and work more consistently when the blkid
4415 cache file is not available or set to /dev/null. (Addresses Debian
4416 Bug #290530 and #292425)
4418 Badblocks will now correctly display block numbers greater than
4419 999,999,999 in its progress display.
4421 The tune2fs program will not allow the user from setting a ridiculous
4422 number of reserved blocks which would cause e2fsck to assume the
4423 superblock was corrupt. E2fsck's standards for what is a ridiculous
4424 number of reserved block has also been relaxed to 50% of the blocks in
4427 The blkid library will return vfat in preference to msdos, and ext3 in
4428 preference to ext2 (if the journalling flag is set) so that mount will
4429 do the right thing. (Addresses Debian bug #287455)
4431 Mke2fs will now use the -E option for extended options; the old -R
4432 (raid options) option is still accepted for backwards compatibility.
4433 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
4435 Mke2fs will now accept a size in megabytes, gigabytes, and other units
4436 (via "32m" or "4g" on the command line) if the user finds this more
4437 convenient than specifying a block count.
4439 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
4440 cache conherency problem.
4442 Debugfs now supports a new command, set_inode_field, which allows a
4443 user to manually set a specific inode field more conveniently, as well
4444 as set entries in the indirect block map.
4446 Debugfs's set_super_value command has been enhanced so that the user
4447 can set most superblock fields, including the date/time fields and
4448 some of the more newsly added superblock fields.
4450 E2fsprogs programs now accept an offset to be passed to the file
4451 specifiers, via the syntax: "/tmp/test.img?offset=1024".
4453 E2fsprogs programs will now accept blocksizes up to 65536; kernel
4454 support on the x86 doesn't exist for now, but it can be useful on
4455 other architectures with page sizes greater than 4k. There are 2.6
4456 kernel patches out there which enable this, but they are of this
4457 writing still experimental.
4459 The e2image command now takes the -s option which will scramble
4460 directory entries for raw image files.
4462 Fix a file descriptor leak in the filefrag program.
4464 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
4467 Fix bug in debugfs where kill_file would lead to errors when deleting
4468 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
4470 Fix bug in the blkid library when detecting the ocfs1 filesystem
4472 Remove obsolete EVMS 1.x and a.out DLL support.
4474 E2fsck will attempt to recover from a journal containing illegal blocks.
4476 Fixed two potential ordering constraint problems in e2fsck which might
4477 cause the filesystem to be corrupted if e2fsck is interrupted during a
4478 (extremely narrow) race window. Thanks to Junfeng Yang from the
4479 Stanford Metacompilation group for pointing this out.
4481 Fixed bug in e2fsck where it would not accurately detect whether or
4482 not the system is running on adaptor if the ACPI device representing
4483 the AC adapter didn't correspond to the what was used on IBM
4486 Change e2fsck to accept directories greater than 32MB.
4488 Fix e2fsck so that a checkinterval of zero disables a time-based check
4491 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4492 to the PAGER environment variable. (Addresses Debian Bug #239547)
4494 Tune2fs will not mark rewrite the superblock if the feature bitmasks
4497 The debugfs program will set the filetype information when creating a
4500 Add debugfs -d option to use a separate source of data blocks when
4501 reading from an e2image file.
4503 Add e2image -I option which allows the e2image metadata to be
4504 installed into a filesystem.
4506 Fixed bug in the badblocks program which caused "done" to always
4507 appear in english even when a translation was available. (Addresses
4510 The blkid program has a new option -o which controls the output format
4511 of the blkid program; this is makes blkid more convenient to use in
4514 Fix a minor bug in uuid library, which was not using the full 14 bits
4515 of clock sequence when generating UUID's.
4517 Fix a Y8.8888K problem in the uuid library.
4519 Logsave now creates a new session id for itself to avoid getting
4520 killed by init whan transitioning between init levels.
4522 Change the licensing of the UUID library to be the 3-clause BSD-style
4523 license; this allows Apple to use the uuid library in Darwin.
4525 Add ocfs and ocfs2 probe support into the blkid library.
4527 Fix a memory and file descriptor leak in the blkid library.
4529 The blkid library will revalidate the device if the system time is
4530 earlier than last verification time of the device, since that
4531 indicates that the system time is probably nottrustworthy.
4533 The blkid library will override the default location of the blkid.tab
4534 file by the BLKID_FILE environment variable, if it is available.
4536 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4538 Add various portability fixes for lame new versions of glibc, Darwin
4539 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
4540 Bugs #239934, #264630, #269044, #255589, #289133)
4542 Add support for Windows 9x/NT under Cygwin.
4544 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
4545 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
4547 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
4549 Update the rpm spec files so that it works better with Fedora core 2
4552 Fixed various Debian packaging issues (see debian/changelog). In
4553 particular, fixed the Debian initrd scripts. (#241183, #248050,
4560 Fixed various gcc -Wall warnings.
4562 The uuid library now has new functions uuid_unparse_upper() and
4563 uuid_unparse_lower() which forces the case of the hex digits to be
4564 upper case, or lower case.
4566 The build process has been speeded up by enhancing the subst program
4567 to update the modtime on the generated files even when the generated
4568 file hasn't changed.
4570 The uuid library now uses C99 stdint.h types instead of custom types.
4572 Updated config.guess and config.sub with newer versions from the FSF.
4574 Removed out of date .cvsignore files from the source distribution.
4576 The ext2fs_unlink() function will return an error if both the name and
4577 inode number are unspecified, to avoid doing something surprising
4578 (such as unconditionally deleting the first directory entry).
4579 Directory entries are now deleted by coalescing them with the previous
4580 directory entry if possible, to avoid directory fragmentation. This
4581 is not an issue with the e2fsprogs suite, but may be a problem for
4582 some of the users of libext2fs, such as e2tools.
4584 Add support for version numbers of the form "1.36-rc1".
4586 Fix build of mke2fs.static.
4588 Add basic ext2fs library support for large (EA in inode) inodes.
4590 The test_io mechanism can now abort after n reads or writes to a
4591 particular block. The block is specified by TEST_IO_BLOCK environment
4592 variable, and the read/write count by the TEST_IO_READ_ABORT and
4593 TEST_IO_WRITE_ABORT environment variables. The block data is now only
4594 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4596 UUID_DEFINE() in the uuid library now creates a static variable, with
4597 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4598 be used in header files.
4600 Add support for the install-strip and install-shlibs-strip targets, as
4601 suggested by the GNU coding guielines. "make install" no longer
4602 strips the binaries which are installed.
4604 Remove support for the --enable-old-bitops configure option which was
4605 only for very old sparc systems.
4607 Remove support for --enable-clear-htree; this was only needed during
4608 the early development of the htree patch.
4610 Use Linux-kernel-style makefile output so it is easier to see compiler
4613 Update gettext files to version 0.14.1.
4615 Update to use autoconf 2.5x.
4617 Improved support for compiling e2fsprogs under dietlibc.
4619 Make e2fsprogs portable to Solaris and FreeBSD systems.
4621 Add blkid_verify(), blkid_get_library_version(), and
4622 blkid_parse_version_string() functions to the blkid library.
4624 Add pkg-config files for e2fsprogs's libraries.
4626 Fix "make uninstall" to so that it removes everything that is installed.
4628 Add a configure --enable-maintainer-mode option which enables the
4629 makefile rules to rebuild the configure script from configure.in, and
4630 to reubuild the .gmo files in po directory.
4632 Drop the sparc assembly bitwise operations; it's less efficient
4633 than the GCC 3.4 compile code and triggers compiler warnings on
4634 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

4638 E2fsprogs 1.35 (February 28, 2004)
4639 ==================================
4641 E2fsck has a new -k option, which in conjunction with the -c options,
4642 preserves the existing badblocks list.
4644 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.

4657 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4658 dump due to a division by zero error. (Addresses Debian bug #207082)
4660 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4661 when reconnecting a directory requires creating a lost+found
4662 directory. (Addresses Debian bug #219640).
4664 Fixed a bug where e2fsck would bomb out if a journal needed to be
4665 replayed when using an alternate superblock.
4667 E2fsck will give an extra grace period before actually forcing a check
4668 if the laptop is running on battery. The next time fsck runs while
4669 the system is on the AC mains, or after the grace period is exceeded,
4670 the filesystem will be checked. (Addresses Debian bug #205177)
4672 E2fsck will inform the user when there are 5 or fewer mounts before a
4673 filesystem check will be forced. (Addresses Debian bug #157194)
4675 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4676 We now correctly handle the case where there is an overlap between a
4677 block group descriptor or a superblock and a bad block indirect block.
4678 In the case where the indirect block is corrupted, we now suggest
4681 Fix byte swap bugs in e2fsck that caused the journal backup location
4682 in the superblock and symlinks created by SE Linux to be cleared
4683 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
4685 E2fsck -c now replaces the current list of bad blocks with the ones
4688 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4689 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4691 Fix a potential bug in e2fsck which could cause it to core dump when
4692 trying to print the location of the backup superblock.
4694 Protect against a potential core dump in e2fsck when printing a
4695 message about backup superblocks.
4697 Add support for backing up the journal inode location in the
4698 superblock. E2fsck will automatically save the journal information in
4699 the superblock if it is not there already, and will use it if the
4700 journal inode appears to be corrupted. ext2fs_add_journal_inode()
4701 will also save the backup information, so that new filesystems created
4702 by mke2fs and filesystems that have journals added via tune2fs will
4703 also have journal location written to the superblock as well.
4704 Debugfs's logdump command has been enhanced so that it can use the
4705 journal information in the superblock.
4707 E2fsck will now update all superblocks when moving the journal inode.
4709 Shrink the size of the e2fsck executable by moving some initialized
4710 variables to the BSS segment.
4712 E2fsck will avoid printing the ^A and ^B characters which bracket the
4713 progress bar when stdout and stdin are a tty device instead of a pipe
4714 to another program. (Addresses Debian bug #204137)
4716 Debugfs's mkdir command will automatically expand the directory if
4717 necessary. (Addresses Debian Bug: #217892)
4719 Fixed a bug in debugfs so that copying a file from /dev/null uses the
4720 correct mode bits. (Addresses Debian Bug: #217456)
4722 If the environment variables DEBUFS_PAGER and PAGER are not set,
4723 debugfs now searches for the appropriate pager to use, beginning with
4724 /usr/bin/pager, and then falling back to 'more' and 'less'.
4725 (Addresses Debian bug #221977)
4727 Debugfs will now support 2.6 device numbers where the major or minor
4728 number may be larger than 255. (Addresses Sourceforge bug #865289)
4730 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
4732 Chattr now stops processing options when it sees '--'. (Addresses
4735 Fix regression tests so they work correctly when e2fsprogs is compiled
4736 with configure --disable-htree.
4738 Fix bug in uuid library when there is no network card and the library
4739 is generating a time-based uuid. The random MAC address was not
4740 correctly generated to be a multicast address.
4742 Add compile_et extensions from Heimdall that were missed the first time
4745 Fix bug in badblocks when using O_DIRECT; we need to make sure that
4746 we're reading from an offset which is page aligned. For read-only and
4747 read-write tests, we try to recover after an error so that we can
4748 continue reading on page-aligned boundaries. (Addresses Debian Bug
4751 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
4754 Updated and clarified various man pages. (Addresses Debian Bug
4755 #206845, #222606, #214920, #232406)
4757 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
4759 Fixed various Debian packaging issues (see debian/changelog).
4764 Fixed a build problem so that e2fsprogs would compile with the
4765 --enable-profile option to configure selected. (Addresses Sourceforge
4768 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
4769 Bugzilla Bug #112448)
4771 Centralize code which calculates the location of the superblock
4772 and block group descriptors so that it is in a single library routine.
4774 Added two new functions, ext2fs_file_open2() and
4775 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4777 Fix compile_et to output the correct prototype for
4778 initialize_xxx_err_table_r() in the header file. (Addresses Debian
4781 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4783 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4784 present. This is for when we try stuffing an int into void * pointer.
4786 Fix type-punning which can cause gcc 3.x to miscompile code by getting
4787 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
4788 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4789 **'. The EVMS code uses an ugly union approach since we don't want to
4790 modify the EVMS interfaces.
4792 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4793 aid build process on systems can use invoke GNU make as "gmake".
4795 Added regression testing for mke2fs.
4797 Fixed gcc -Wall nitpicks.
4799 Fixed various compiler warnings.
4801 Add portability fixes for FreeBSD and for using fsctl under Darwin to
4802 support ext2 ioctl's.
4805 E2fsprogs 1.34 (July 25, 2003)
4806 ===============================
4808 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4809 a tight loop while waiting for a child fsck to exit in some cases.
4810 This burns CPU times which slows down the low-level filesystem check.
4812 Added code to mke2fs to assure that the default block size for a
4813 filesystem is at least as big as the sector size of the device, if it
4816 Changed mke2fs and resize2fs to round the default size of a filesystem
4817 to be an even multiple of the VM pagesize in order to avoid a Linux
4818 kernel bug introduced when the storage of the buffer cache was moved
4819 into the page cache.
4821 Mke2fs will warn the user when creating a filesystem with journaling
4822 and a blocksize greater than 4096. (Addresses Debian bug #193773)
4824 Fixed a bug in resize2fs which caused it to fail on filesystems with a
4825 non-empty bad block list. Resize2fs now discards any blocks on the
4826 badblock list which are no longer part of the filesystem as the result
4827 of a filesystem shrink. (Note: this means that shrinking and then
4828 enlarging a filesystem is no longer a reversible operation;
4829 information about bad blocks in the part of the filesystem which is to
4830 be chopped off will be lost.)
4832 Changed resize2fs so the user can use prefixes to specify the units of
4833 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4834 and to make the error and informational messages explicitly display
4835 the blocksize used by the filesystem, in order to avoid confusion.
4836 (Addresses Debian bug: #189814)
4838 Added a new debugfs command, dump_unused, which dumps the contents of
4839 all unused blocks to stdout. (Useful as an emergency try-to-find
4840 deleted data command.)
4842 Added a new debugfs command, imap, which prints the location of a
4843 specified inode in the inode table.
4845 Fixed a bug in the badblocks program which caused it to use one bit of
4846 randomness in its non-destructive read/write test, instead of using a
4847 full 8 bits of randomness.
4849 Added a new option (-t) to badblocks, which allows the user to control
4850 the test pattern(s) used when checking a disk.
4852 The blkid probe function now more correctly detects UDF filesystems.
4854 Fixed a bug in the blkid library which caused it to not update its
4855 cache if a filesystem changes from having a label to not having a
4858 Fixed a bug in the blkid library wihch could avoid an infinite loop
4859 in blkid_find_dev_with_tag() if /proc is not mounted and there the
4860 /etc/blkid.tab file has not yet been created.
4862 Fixed the badblocks program so that the destructive read/write test
4863 honors the -c option, and to use O_DIRECT when possible to avoid
4864 thrashing the system block buffer cache.
4866 Fixed various NLS issues.
4867 - Added Czech and Swedish translations
4868 - Removed testing NYC translation
4869 - Fixed NLS support for message abbrevations in e2fsck
4870 - Remove de-utf.po, since we shouldn't have two versions using different
4872 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
4873 simplify the statistics reporting in e2fsck.
4875 Changed configure.in so that its defaults for *BSD systems no longer
4876 build an fsck wrapper, and not to install in /usr/local by default.
4878 Fixed some minor spelling errors/typo's in e2fsck and the configure
4881 Fixed various Debian packaging issues (see debian/changelog).
4883 Updated and clarified man pages. (Addresses Debian Bug #195616)
4888 Fix gcc -Wall nitpicks.
4890 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4891 NLS support by default. (Added partial workaround for gettext/Darwin
4892 incompatibility problems.)
4894 Added full MIT KRB5 and Himdall compaibility support to the com_err
4895 library and the compile_et program. (Addresses Debian bug #191900)
4897 Added the blkid_known_fstype() function to the blkid library, which
4898 returns true if it is passed a filesystem type which is recognized by
4899 the blkid probing functions.
4901 Improved the documentation for the blkid library.
4903 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4904 returns the hardware sector size of a device, if it is available.
4906 Added a dependency in the blkid library's .so file to the uuid
4907 library, since the former uses the latter. (Addresses Debian bug
4910 Added --with-diet-libc and --disable-evms to the configure script.
4912 Fixed a minor memory leak in the badblocks program.
4914 Fixed a portability problem in tune2fs --- not all systems have strptime().
4916 Fixed a portability problem in debugfs with the use of getopt() more
4917 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
4920 Add support Windows support to ext2fs_get_device_size().
4922 Added (normally disabled) debugging code to the Unix I/O manager which
4923 causes it to disable all userspace caching if the NO_IO_CACHE is
4926 Changed the test I/O manager so it can always be linked into e2fsck,
4927 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4928 configure script. The test I/O manager will only print any debugging
4929 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4930 variables are set, which specifies which I/O operations are logged and
4931 a block number to watch, respectively. The log messages are sent to
4932 stderr by default, unless a filename is specified via the
4933 TEST_IO_LOGFILE environment variable.
4936 E2fsprogs 1.33 (April 21, 2003)
4937 ===============================
4939 Added a new utility program, logsave, which captures the output of a
4940 command in a log file, even if the containing directory hasn't been
4941 mounted yet (in which case the it saves the output in memory until it
4942 can write out the logfile). This is useful for capturing the
4943 output of fsck during the boot sequence.
4945 Fixed some portability problems that were causing problems under
4946 the Cygwin32 environment.
4948 Mke2fs now interprets a negative number to the -b option as a minimum
4951 Fixed a bug in mke2fs which was incorrectly checking the argument to
4952 the -g option if the default block size was used. (Addresses Debian
4955 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4956 it can not find filesystem checkers for jfs, reseirfs, and xfs.
4958 E2fsck now updates the global free block and inode counters from the
4959 block group specific counters quietly. This is needed for an
4960 experimental patch which eliminates locking the entire filesystem when
4961 allocating blocks or inodes; if the filesystem is not unmounted
4962 cleanly, the global counts may not be accurate.
4964 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4965 2.0 is not yet supported; this only pulled in the bug fixes: fixed
4966 possible hangs caused by bugs in calling waitpid, and not setting the
4967 pipe to non-blocking mode; also fixed a file descriptor leak; made
4968 sure all functions call log entry/exit functions.)
4970 Badblocks now flushes its output file as bad blocks are discovered.
4972 The uuid library is now more paranoid about assuming the correctness
4973 of the /dev/random device; it mixes in a stream of bytes from
4974 random/srandom, just in case.
4976 Update Debian files to reflect the fact that I am now the Debian
4977 maintainer of e2fsprogs. Other various Debian-specific packaging
4980 Move the source tarball generation functions from the top-level
4981 makefile to the util/gen-tarball script.
4983 Updated the Turkish .po translation file.
4985 Added Heimdal and MIT krb5 extensions to the com_err library to make
4986 it more compatible with com_err libraries from those distributions.
4988 Changed dumpe2fs to always display the superblock fields relating to
4989 the journalling and/or directory indexing feature even if those
4990 features are not enabled.
4992 Updated and clarify copyright statement vis-a-vis alpha releases of
4995 The ss library will now try to dynamically link to the readline
4996 library and use it if it is present in the system. This means that
4997 the debugfs program now has line editing and history features. The
4998 SS_READLINE_PATH environment variable is used to find a readline or
4999 readline-compatible library.
5001 E2fsck now finds most duplicate filenames (all when rebuilding all
5002 directories via the -D option) and offers to delete or rename
5003 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
5005 Fix bug in e2image. When writing out a raw image file, include data
5006 blocks from symlinks that do not store the symlink within the inode.
5008 Fix bug in resize2fs which incorrectly moved the block and inode
5009 bitmaps for sparse superblock filesystems and incorrectly marked
5010 blocks as in use. (Addresses Debian bug #174766)
5012 Added a new shared library, the blkid library, which efficiently
5013 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
5014 and UUID filesystem specifiers without needing to search all of the
5015 devices in the system. Instead, the device is looked up in a cache
5016 file, and then verified to make sure the blkid cache is correct.
5018 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
5019 the device name, using the blkid library. (Addresses Debian bugs
5022 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
5023 used for spaces in device labels.
5025 Removed 32-bit limitations for debugfs's dump command.
5027 If the user specifies a large number of inodes, Mke2fs will
5028 automatically adjust the number of blocks per group to find a valid
5029 set of filesystem parameters.
5031 Add workaround to detect broken MD devices where when some of the
5032 underlying devices are marked read-only, writes to the MD device are
5033 silently dropped. E2fsck will detect if there is an attempt to run
5034 the journal twice, and abort with an error if this is the case.
5035 (Addresses IBM Bugzilla bug #1226)
5037 E2fsck will print an error if more than one of the -p/-a, -n or -y
5038 options are specified.
5040 E2fsck will fix HTREE corruptions in preen mode, without stopping the
5041 boot process. This is needed because the 2.4 ext2 filesystem
5042 accidentally had the INDEX_FL backwards compatibility code removed.
5044 Mke2fs no longer creates filesystems with the dir_index flag set by
5045 default; the user has to specifically request it.
5047 Update and clarified various man pages. (Addresses Debian bugs
5048 #173612, #175233, #175113, and #170497, #185945, #188318)
5050 Created man page for the mk_cmds program (from the libss library).
5055 Fix various gcc -Wall nits.
5057 Fixed a lot of portability problems that caused e2fsprogs not to build
5058 successfully under Solaris and Apple/Darwin.
5060 Fixed a Makefile dependency to allow building e2fsprogs using parallel
5063 Changes to create a subset distribution which consists only of the
5064 et, ss, uuid, and blkid libraries. The configure script and top-level
5065 makefile were changed to support working with a subset distribution.
5067 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
5068 actually used, and might people who are looking for
5069 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
5071 Updated debian files to fix a number of Lintian warnings.
5073 Updated config.guess and config.sub with newer versions from the FSF.
5075 Removed unnecessary libraries from being linked into the fsck, lsattr,
5076 chattr, and blkid executables.
5078 E2fsprogs 1.32 (Nomvember 9, 2002)
5079 ==================================
5081 Fixed a bug in the Unix I/O routines which caused needless writebacks
5082 of clean blocks from the unix_io cache (they were erroneously marked
5083 as being dirty, so they were getting written back to disk before
5084 getting evicted from the disk cache). This was harmless, but it
5085 significantly slowed down e2fsck.
5087 Made some other minor optimizations to the Unix I/O routines to save a
5088 small amount of CPU time.
5090 Updated internationalization files.
5093 E2fsprogs 1.31 (Nomvember 8, 2002)
5094 ==================================
5096 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
5097 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
5098 handling for child process that die unexpectly. Add a hack to force
5099 mkfs to create filesystems that won't cause problems with hardware
5100 that has 2k or 4k minimum blocksize requirements. Read from child
5101 processes in non-blocking mode, so that the GUI continues to update.
5103 Fix e2fsck so that it returns the appropriate exit code when the root
5104 filesystem has been changed, so that system's rc scripts will be told that
5105 the system needs to be rebooted.
5107 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
5108 was set, some of the descriptor blocks that should have been written
5109 out were getting skipped.
5111 Changed e2fsck to force out changes to the backup copies of the
5112 superblock and block group descriptors when important changes are made
5113 to those data structures.
5115 Fix a bug where e2fsck could erroneously mark a filesystem as being
5116 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
5117 introduced in e2fsprogs 1.28.)
5119 If journal debuging is enabled using --enable-jbd-debug, the debugging
5120 level is now set via the E2FSCK_JBD_DEBUG environment variable.
5122 If byteswapping support is disabled using configure --disable-swapfs,
5123 skip the tests which depend on byte-swapping, so that "make check"
5126 Lshattr will now display the indexed directory flag. Also, some of
5127 the more esoteric compression flags are supressed unless compression
5128 support has been enabled.
5133 E2fsprogs 1.30 (October 31, 2002)
5134 =================================
5136 When resizing a filesystem, and inodes need to moved, resize2fs will
5137 update the inode's ctime field, and the mtime field of the containing
5138 directories, so that incremental backups using dump/restore will work
5141 In order to avoid spurious errors, e2fsck wil check the last
5142 superblock write time to determine whether or not it can safely use
5143 the LOW_DTIME checks to determine if there are inodes on the orphan
5144 inode linked list that had somehow gotten disconnected. (Addresses
5145 Sourceforge bug #620980)
5147 Partition in /proc/partitions that being with the string "lvm" are
5148 considered real partitions even if they do not end with a number.
5150 Fixed a bug in the the uuid generation function, where if /dev/urandom
5151 is not present, but /dev/random is, and there isn't sufficient
5152 entropy, the get_random_byte function could spin a loop forever.
5154 E2fsck, mke2fs, etc. will now reliably notice when image files are
5155 mounted using the loopback interface. (Addresses Sourceforge bug
5158 When flushing buffers (as is done by badblocks, for example) check to
5159 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
5160 FDFLUSH ioctl which causes the MD device driver which causes confusing
5161 syslog messages about obselete ioctl messages. (Addresses Sourceforge
5164 Debugfs's write command now checks to see if the destination filename
5165 exists before creating it. (Addresses Sourceforge bug #478195.)
5167 When installing man pages, search for compressed man pages using all
5168 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
5170 Fixed a bug in fsck where multiple filesystems specified on the
5171 command were not being checked in parallel due to a logic bug
5172 introduced to support the FSCK_MAX_INST environment variable.
5174 We have added a new superblock field, s_mkfs_time, which indicates
5175 when a filesystem was created. It is set via mke2fs, and printed out
5176 by dumpe2fs, but is not actually touched by the kernel.
5178 Dumpe2fs has been made more robust by not aborting if there is an
5179 error reading the block/inode bitmaps; instead it will still print out
5180 the location of the block/inode bitmaps and inode table.
5182 Add support for the an alternative block group descriptor layout which
5183 allows for on-line resizing without needing to prepare the filesystem
5184 in advance. (This is the incomat feature flag meta_bg.)
5186 Add support for storing default mount options in the superblock, so
5187 that the filesystem can be mounted with specific mount options without
5188 needing to specify them on the mount command line or in the /etc/fstab
5191 Add support for a new inode flag, which is to be used for indicating
5192 the top of directory hierarchies for the Orlov block allocator.
5194 Fix e2fsck so that if it creates the lost+found directory, it does so
5195 with the more apporpriate permissions of 0700. Also change
5196 mklost+found so that it also creates the directory 0700.
5198 Fixed format bug in e2fsck if NLS is in use.
5200 Add a German translation for e2fsprogs's NLS support.
5202 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
5203 the beginning of the inode table. This won't matter much, since if
5204 there is a bad block at the beginning of the inode table, the root
5205 directory won't be available. But at least e2fsck won't crash in this
5208 Fixed endian problems in the htree code for e2fsck and debugfs.
5210 When byte-swapping a filesystem on a PPC architecture, byte-swap the
5211 bitmaps since the historical big-endian ext2 variant had byte-swapped
5212 bitmaps, and the ext2fs library assumes this. This fixes the
5213 regression test suite on PPC machines.
5215 Fix e2image so that it handles a bad block in the inode table
5218 E2fsck now uses a more sophisticated algorithm to salvage corrupted
5219 directories that recovers more information in the corrupted directory
5222 E2fsck now performs additional consistency checks on indexed (HTREE)
5225 Fix bug where efsck might get confused about whether a completely
5226 empty directory block is an empty leaf block or an interior htree
5227 node. This could cause e2fsck to get confused into think that a valid
5228 indexed directory was corrupted.
5230 E2fsck no longer creates an empty directory entry at the end of a
5231 directory block when optimizing a directory. This would cause some
5232 earlier versions of the dxdir kernel code to corrupt the directory
5233 when attempting to split a node containing an empty directory entry.
5235 E2fsck could sometimes in rare circumstances leave the indexed flag
5236 set after a small directory was optimized by compressing it instead of
5237 indexing it. (This should never happen in real life, since
5238 directories that small wouldn't have been indexed, but better safe
5241 E2fsck now only updates the master superblock in all cases. This
5242 slightly shortens its run time.
5244 Ext2ed can deal with directory entries of length 0; previously it
5245 would get stuck in an infinite loop.
5247 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
5248 specifiers. (Sourceforge patch #613447)
5250 Badblocks will now work correctly on read-only devices such as
5251 CD-ROM's. (Sourceforge patch #600451)
5253 Updated and clarified man pages. (Addresses Debian bug #167108)
5256 E2fsprogs 1.29 (September 24, 2002)
5257 ===================================
5259 Fixed a bug in e2fsck which could corrupt a directory when optimizing
5260 it (via the -D option) or rebuiliding the hash tree index with a 1 in
5261 512 probability, due to a fence post error.
5263 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
5266 Mke2fs now enables the directory indexing flag by default. (Since
5267 this is a compatible feature flag, it's safe to do so.)
5269 Tune2fs will support setting the directory indexing feature flag. It
5270 will automatically set up the default hash algorithm and hash seed
5271 fields in the superblock.
5273 If the bone-headed user enters the root filesystem twice in
5274 /etc/fstab, the -R option which skips the root filesystem will skip
5275 all of them. (Addresses Debian bug #159423). Note! This is not a
5276 precedent for dealing intelligently with any other kind of doubled
5277 entry in /etc/fstab!
5283 Removed perror declaration in lib/et/internal.h. All modern systems
5284 can be expected to define perror() these days. Besides, the lib/et
5285 code wasn't using perror at all anyway. :-)
5288 E2fsprogs 1.28 (August 31, 2002)
5289 ================================
5291 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
5292 for setting the htree flag is not included yet, although it can be
5293 manually turned on via the debugfs program.
5295 Clarified e2fsck error message which is printed when it cannot find
5296 sufficient contiguous block when relcating filesystem metadata.
5298 Added support for building an EVMS plugin module for ext2/3. This
5299 module is substantially the same as the EVMS module shipping with EVMS
5300 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
5301 for use with EVMS 1.0 (which did not include the ext2 plugin module),
5302 if the configure --enable-old-evms flag is given.
5304 Fsck will search through EVMS volumes when trying to resolve
5305 filesystem specifications such as LABEL=xxx or UUID=xxx.
5307 Added a new utility program, /sbin/findfs, which will return
5308 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
5311 Update and clarified various man pages. (addresses Debian Bug #145044,
5312 #146437, #131350, #151990, #144621, #141938)
5314 If there are no filesystems specified on fsck's command line, fsck now
5315 treat that as if the -As options were given. Previously it would
5316 simply do nothing. (Addresses Debian Bug #153102)
5318 Mke2fs no longer treats a failure to be able to clear the MD signature
5319 at the end of the filesystem as a fatal error. (Addresses Debian Bug
5322 The e2p library functions (which are used by lsattr and chattr) now
5323 double check to make sure the file is a regular file or directory
5324 before attempting to use the ext2 ioctls. Some device drivers
5325 unfortunately respond to the ext2 ioctl's with unknown behaviour.
5326 (Addresses Debian Bug #152029).
5328 The extended attribute handling has been updated to correspond with
5329 the latest V2 bestbits ACL code.
5331 Fixed bug in e2fsck which caused it to not clear the dtime field when
5332 processing truncated inodes on the orphan list. This could cause data
5333 loss(!) if a filesystem is rebooted before a truncate has been
5336 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
5337 algorithms. This makes e2fsck much faster in the case of severely
5338 corrupted filesystems where a large number of blocks are claimed by a
5339 large number of inodes. (Thanks to the 2.5 IDE device driver for
5340 inspiring this work.)
5342 Resize2fs has been significantly sped up when shrinking and expanding
5343 a filesystem by a very small number of blocks (for example, when EVMS
5344 is converting a partition to be an EVMS legacy volume).
5346 Added a new option to e2fsck, -D, which will optimize or compress all
5347 of the directories in the filesystem.
5349 E2fsck now catches SIGINT and SIGTERM to make sure it will can
5350 properly clean up and only exit at safe points. Fsck will pass
5351 SIGINT/SIGTERM to its child processes, and wait until they have all
5352 exited before it exits.
5354 The uuid parsing code in the uuid library now properly complains when
5355 an illegally formated uuid is presented to it. (Addresses Debian bug
5358 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
5359 and 2.4.17, since the workaround can cause problems when using a 2.4
5360 kernel with an old version of glibc built with the 2.2 headers.
5362 Fixed a bug in mke2fs where it wasn't properly clearing the initial
5363 superblock used by other filesystems. (Addresses Debian bug #147256.)
5365 Added support for the synchronous directory feature written by Andrew
5368 The debugfs program can delete directories using the rmdir command.
5370 Add support for 8k and 16k filesystems (for systems with page sizes
5371 that are greater or equal to 8k or 16k, respectively). Note that
5372 these filesystems can not be mounted on x86 systems, or other systems
5373 with only 4k page sizes, due to limitations in the current Linux VM
5376 Resize2fs requires that the filesystem state be valid and have no
5377 errors; otherwise, e2fsck -f must be run first. (Previously it simply
5378 required that the last fsck time be greater than the last mount time.)
5380 Configure now defaults the man pages directory to /usr/share/man on
5383 E2fsck now offers to truncate inodes which contain too many blocks (so
5384 that i_blocks would overflow. Also fixed handling of large sparse
5387 E2fsck now more completely checks for symlink validity, including
5388 requiring NULL termination and length checks.
5390 E2fsck will offer to try forcing a disk write to remap a bad block
5391 after finding a read error when reading a filesystem metadata block.
5393 Fixed a bug in debugfs which caused the -b and -s options to crash
5394 debugfs, as well as breaking the testb, setb, and clearb functions.
5396 Added a bmap command to debugfs which calculates the logical to
5397 physical block mapping for a particular inode.
5399 Fixed a bug in code which checked to see if a device was mounted which
5400 sometimes (rarely) failed in the case of a plain file.
5402 Fixed a bug in resize2fs where when it reported an error, it would
5403 print a message erroneously indicating that the filesystem had been
5404 resized before it aborted.
5406 When resizing a plain file which is smaller than the requested size,
5407 resize2fs will attempt to extended the file so that programs like
5408 e2fsck will not complain that the file is too small.
5410 Resize2fs will print the actual new size of the filesystem when it is
5413 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
5414 information on big-endian systems.
5420 Fixed collisions with C++ reserved words.
5422 Added portability fixes for building e2fsprogs on the HURD and AIX.
5424 Added the ext2ed program for creation of test cases. (ext2ed has many
5425 limitations and bugs which make it unsuitable for production use.)
5427 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
5428 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
5429 name_len field is byte swampped on big-endian machines, since in the
5430 V2 structure, name_len is a char field which is doesn't need to be
5431 byte swapped --- except if an old-style kernel had byte-swapped the
5432 name_len field as part of the V1 structure.
5435 E2fsprogs 1.27 (March 8, 2002)
5436 ==============================
5438 The warning messages for mke2fs now go to standard error.
5440 Fixed to make sure "make check" runs all of the test programs with
5441 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
5443 The mke2fs program checks the boot sector for the BSD disk label, and
5444 avoids erasing it if it is there.
5446 Fixed a bug in e2fsck which caused it to core dump if the journal
5447 inode was missing when it was supposed to be there.
5449 E2fsck now prints ranges in pass 5 when printing deltas for the block
5452 Debugfs's "ls -l" command now will print out the file type information
5453 in the directory entry.
5455 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
5456 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
5458 Debugfs can now examine the experimental directory indexing
5461 Fixed bug in debugfs which caused it to core dump if modify_inode is
5462 called without an open filesystem.
5464 The debugfs lsdel command now runs its output through a pager first.
5466 When installing manual pages, remove the compressed manual pages first.
5468 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
5470 Fix the 2.4 resource limitation workaround introduced in 1.26 which
5471 actually broke things on mips32, sparc32, and Alpha platforms.
5473 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
5474 (which is required by the newer libintl libraries).
5479 Fixed various gcc -Wall complaints.
5481 Fixed a few memory leaks in the e2fsck journaling code, and in the
5482 ismounted code checking for a swap device.
5484 Add new inode I/O abstraction interface which exports an inode as
5487 Exported ext2_file_flush as a public interface.
5489 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5491 Lots of small random portability fixes to make e2fsprogs build under
5492 AIX --- even without the 5L compatibility toolkit, and even using the
5493 uber-crippled AIX native C compiler.
5496 E2fsprogs 1.26 (February 3, 2002)
5497 =================================
5499 Dumpe2fs will keep going now if the bad block inode can't be read.
5500 (Previously it stopped with a fatal error.)
5502 E2fsck will now give an opportunity to run the journal even if the
5503 recovery flag is not set. This is the default behaviour if e2fsck is
5504 using a backup superblock, since the needs_recovery flag will never be
5505 set in the backup superblock copies.
5507 E2fsck now automatically finds the backup superblock/group descriptors
5508 even when the primary superblock is completely destroyed for 2k and 4k
5509 filesystems. (Previously it just guessed/assumed that we were dealing
5510 with a 1k filesystem in that case, and users had to manually specify
5511 the backup superblock number.)
5513 Fixed a bug in e2fsck where it dereferences a null pointer when there
5514 is a problem opening a filesystem in preen mode.
5516 E2fsck now handles external journals correctly; previously it trashed
5517 the external journal device if the journal needed to be replayed.
5519 Work around ulimit incompatibility problem caused by recent 2.4
5520 kernels; the unix IO module will automatically try to set any resource
5521 limits to be infinite on startup.
5523 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5524 bitmap if it wasn't present and the blocksize was 2k or 4k.
5525 (Addresses Debian Bug #116975)
5527 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5528 clearing the new V2 fields if they do not make sense or if the ext3
5529 superblock is version 1 superblock.
5531 E2fsck will automatically relocate the ext3 journal from a visible
5532 file (i.e., /.journal) to an hidden inode if the filesystem has been
5533 opened read/write. This allows the users to add a journal while the
5534 filesystem is mounted, but the next time the system is rebooted, the
5535 journal file will disappear. This avoids problems with backups,
5536 stupid operators with superuser bits, etc.
5538 Fix a bug in fsck where it would not support a filesystem type of
5539 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5541 Fsck now supports fstab entries of the form "ext3,ext2". It will also
5542 automatically identify reiserfs filesystems.
5544 The number of processes spawned by fsck can now be limited using the
5545 FSCK_MAX_INST environment variable.
5547 Fsck now searchs the LVM proc hierarchy to find logical volumes which
5548 should be searched for UUID and label information.
5550 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5551 limit if at all possible, when opening a block device. (The filesize
5552 limit shouldn't be applied against writes to a block device.)
5554 In mke2fs and e2fsck, specifying the -c option twice will now do
5555 a read/write test on the disk. Update the man pages to encourage
5556 using the -c option, and to discouraging running badblocks separately,
5557 since users tend to forget to set the blocksize when running
5560 Mke2fs now automatically clears the immutable attribute on a
5561 pre-existing .journal file left over from a previous failed attempt to
5562 add a journal to an alreadyy-mounted filesystem.
5564 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
5567 Mke2fs now creates the lost+found directory with permissions of 0700,
5568 so that files that had previously lived in protected directory are
5569 safe if they get dropped in lost+found and the system administrator
5570 doesn't deal with immediately. (Addresses Debian #bug 118443)
5572 Mke2fs and e2fsck (and all programs that use the
5573 ext2fs_check_if_mounted function) will now properly identify that a
5574 device is mounted, even in cases where devfs has confused things with
5575 multiple devices names with the same identity, or if a dim-witted
5576 system administrator has done something stupid like creating device
5577 file aliases in their home directory. Also now checks for swap devices
5578 by using /proc/swaps. (Addresses Debian bug #106622)
5580 Added a new option (-T) to tune2fs which sets the time a filesystem
5583 Speed up e2image when creating sparse raw image files by optimizing
5584 away excess lseek() system calls.
5586 Fix support of large (> 2GB) files when used as a filesystem in
5587 mke2fs, tune2fs, debugfs, and findsuper.
5589 Debugfs's stat and icheck commands now properly deals with large (>
5592 Debugfs's set_super_value command now prints out the list of valid
5593 superblock fields which can be set using the command.
5595 Debugfs's rm and kill_file command now updates the superblock free block
5596 and inode counts, thus keeping the filesystem consistent.
5598 Debugfs's lsdel command now takes an optional argument which allows
5599 the user to only see the most recently deleted files.
5601 A new command (undel) was added to debugfs which automates
5602 undeleting a deleted inode and linking it back to a directory.
5604 Debugfs's ls command now takes a new option, -d, which lists
5605 deleted directory entries.
5607 Debugfs's testb, freeb, setb, and find_free_block commands now take an
5608 optional count argument.
5610 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5611 be used to signal that a particular inode should not be eligible for
5612 tail-merging --- this is needed for programs like LILO.
5614 The findsuper (an unreleased, uninstalled utility program) has been
5615 improved to add extra validity checks and to add a progress meter.
5616 (It is still an unsupported program; the officially supported way to
5617 recover from a trashed partition table is to use gpart; findsuper is
5618 for wizards only. :-)
5620 Debugfs was fixed to compile with "configure --disable-swapfs".
5622 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
5624 Added new translation file for Turkish.
5629 Fix general gcc -Wall complaints.
5631 E2fsprogs (mostly) works with the dietlibc.
5633 The programming texinfo file has been expanded to include description
5634 of additional libext2fs functions. (Still not compeltely done, but a
5635 lot of the more important functions have been documented.)
5637 Added a umask structure to struct_ext2_filsys, which currently only
5638 modifies the behaviour of ext2fs_mkdir(), but if we add any file
5639 creation functions to libext2fs, we should also make sure they respect
5642 The build-rpm script was fixed to be a bit more safe.
5644 The tests' Makefile now has a way of automating test case creation
5645 for e2fsck, using "make testnew".
5647 Created a new function, ext2fs_dir_iterate2 which passes more
5648 information to the callback function (identical to the one used by
5649 ext2fs_dblist_dir_iterate). The directory iterator functions take a
5650 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5651 directory entries. If the directory entry is deleted, the callback
5652 function will be called with the entry paraemter set to
5653 DIRENT_DELETED_FILE.
5655 Added new functions, ext2fs_inode_alloc_stats and
5656 ext2fs_block_alloc_stats, which takes updates block/inode allocation
5657 statistics in the bitmaps, block group descriptors, and superblock
5658 when inodes or blocks are allocated or deallocated.
5661 E2fsprogs 1.25 (September 20, 2001)
5662 ===================================
5664 This is primarily a bug-fix release; no new features were added, but
5665 there are a number of embarassing bug fixes and cleanups applied.
5667 Fix a bug mke2fs which causes stack garbage to be written to disk when
5668 zapping disk sectors. (This bug could cause mke2fs to core dump for
5669 some kernels, I suspect with security enhancement patches.)
5671 Remove unneeded #include of <linux/config.h> which was breaking
5672 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
5674 Updated tune2fs man page to reflect the fact that adding or removing a
5675 journal doesn't require running e2fsck.
5677 Remove use of AC_REQUIRE from autoconf which had been used to prevent
5678 AC_CANONICAL_HOST from being called twice; unfortunately this causes
5679 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5680 used outside of autoconf macros. Fortunately, it doesn't seem to be
5681 necessary any more, anyway.
5683 E2fsck will now not fall back to an alternate superblock if the user
5684 specifies the superblock location explicitly on the command-line.
5685 This allows easier recovery from a situation where the primary
5686 superblock and block groups are slightly corrupted, but the backup
5687 superblocks are completely broken.
5689 Fix problem which caused compile_et and mk_cmds to blow up if
5690 e2fsprogs was in a directory with a pathname that contained spaces.
5692 We are now more paranoid about checking the entry in /etc/mtab to make
5693 sure the filesystem is really mounted, since some broken distributions
5694 (read: Slackware) don't initialize /etc/mtab before checking non-root
5695 filesystems. (Slackware also doesn't check the root filesystem
5696 separately, and reboot if the root filesystem had changes applied to
5697 it, which is dangerous and broken, but there's nothing I can do about
5700 Make UUID library C++ friendly by adding appropriate extern "C"
5701 declarations and using const in the function declarations.
5703 Fix up the com_err texinfo file so that it can product a valid info
5704 file (previously, it could only be used to generate paper
5705 documentation using texinfo.tex).
5708 E2fsprogs 1.24a (September 2, 2001)
5709 ===================================
5711 Fix brown-paper bug in mke2fs which caused it to segfault when
5712 printing the version string.
5715 E2fsprogs 1.24 (August 30, 2001)
5716 ================================
5718 Revert the BLKGETSIZE64 support, since for some distributions, this
5719 ioctl has been used by an unofficial kernel patch to update the last
5720 sector on the disk, and this was causing disk corruption problems as a
5723 Mke2fs is now more careful about zapping swap space signatures and
5724 other filesystem/raid superblock magic values so that programs like
5725 mount who try to use hueristics to determine the filesystem type of a
5726 partition are less likely to be confused.
5728 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5729 regular file (since Andreas Dilger's on-line resizing tools will set
5732 Fixed some minor texinfo, man pages nits for spelling errors,
5733 texinfo warnings, etc. (Addresses Debian bug #110621.)
5735 E2fsprogs program no longer print the filesystem version number
5736 (i.e. 0.5b), since it only confuses people and doesn't serve any real
5739 E2fsck will once again compile under libc5, since it will supply its
5740 own version of strnlen if necesssary.
5742 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5743 when specifying the external journal device. tune2fs will also search
5744 devices looking for the externla journal debice when removing.
5746 E2fsprogs 1.23 (August 15, 2001)
5747 ================================
5749 Add initial support for extended attributes (EA); e2fsck will
5750 correctly handle a filesystem with EA's and check the EA blocks for
5753 E2fsck's symlink sanity checking has been cleaned up. It now checks
5754 the i_size value of fast symlinks, and checks for immutable flags
5755 being set of symlinks, etc.
5757 E2fsck now offers to clear inodes which are special files that have a
5758 non-zero i_blocks or i_size field. (The i_size field check was in the
5759 previous version of the code, but due to a bug it didn't offer to
5760 clear the inode unless i_size and i_size_high were both non-zero.)
5762 E2image can now create "raw" image files, which only contain the
5763 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5764 debugfs, etc., can be run directly on the raw image file.
5766 Add support for the 64-bit block device patches.
5768 Fixed bugs in creating external journals with a 1k blocksize.
5770 Add initial support for external journals (so long as the external
5771 journal only supports a single filesystem) in e2fsck.
5773 Remove requirement for needing to run fsck on a filesystem after
5774 removing a journal (either internal or external).
5776 The man pages now document how to create and manage external journals.
5778 Speed up the check of an ext3 filesystems by avoiding a needless flush
5779 of all of the superblock and block group descriptors.
5781 Speed up creating an internal journal using tune2fs in the case where
5782 the filesystem has a lot blocks already allocated.
5784 Tune2fs has been fixed to make sure that only error messages go to
5785 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5787 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5788 now not set the sparse_super feature. (Addresses Debian bug #108165)
5790 Add support in fsck for the filesystem type "auto".
5792 Fsck -A will not try to interpret device names for filesystems which
5793 have a pass number is 0. (Addresses Debian bug #106696).
5795 Fsck prints a warning message if now valid filesystems are passed to
5796 it. (Addresses Debian Bug #107458.)
5798 E2fsck now gives an explicit warning if there filesystem still has
5799 errors at the end of the run. (Addresses Debian bug #104502)
5801 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5802 reflects an error. E2fsck will also not run the orphan list if the
5803 filesystem contains errors, since the orphan list might be corrupted.
5805 E2fsck now prints the number of large files when given the -v option.
5807 Fixed minor memory leaks in e2fsck.
5809 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5812 E2fsprogs 1.22 (June 22, 2001)
5813 ==============================
5815 Fixed a bug in e2fsck's handling of orphan inodes which are special
5816 files (i.e., block/character device files, named FIFO's, etc.).
5818 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5819 tune2fs to fail at adding a journal to a mounted filesystem.
5821 Fixed a few big-endian bugs in e2fsprogs
5822 * The directory block functions were accidentally reporting
5823 some directories as corrupted when they weren't.
5824 * If e2fsprogs is compiled --disable-swapfs, the C language
5825 equivalents weren't being included for big-endian platforms.
5826 (Fixes Debian bug #101686).
5828 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
5833 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5834 ioctls, and allow them to be defined for non-i386 platforms.
5836 The uuid.h header file is now protected against multiple inclusions.
5838 E2fsprogs is now being developed using BitKeeper. Changed the test
5839 scripts to deal with BK's stripping CR characgters from text files,
5840 and changed the top-level Makefile.in to avoid including BitKeeper
5841 files when generating the source tarball.
5844 E2fsprogs 1.21 (June 15, 2001)
5845 ==============================
5847 Added new configure flags which allow a subset e2fsprogs to be built;
5848 this is most useful for boot floopies, since the resulting shared
5849 libraries and programs are slimmed down by removing features that
5850 aren't necessary for a boot floppy. The new flags that were added
5851 are: --disable-swapfs, which removes support for byte swapping old
5852 legacy PPC/68k filesystems, --disable-debugfs, which removes support
5853 for debugfs from the libext2fs library, --disable-imager, which
5854 removes support for the e2image program, and --disable-resizer, which
5855 removes support for resize2fs.
5857 E2fsck now prints the number of mounts or days elapsed since the last
5858 check when e2fsck is forced to check an otherwise clean filesystem.
5860 Tune2fs now prints an informative message about how often a filesystem
5861 will be checked when adding a journal to the filesystem, to remind the
5862 user that he/she may want to adjust those parameters using tune2fs
5865 Worked around hurd brain-damage which causes e2fsck to sometimes
5866 believe a filesystem is the root filesystem based on device numbers
5867 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5870 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5871 erroneous error with the -F option was specified.
5873 Fixed a ext3 recovery bug in the revoke handling; synchronized with
5876 Fixed two bugs in e2fsck's handling of dup block handling, dealing
5877 with relatively uncommon edge cases: a directory with an indirect
5878 block which is claimed by another file, and when the last inode in the
5879 filesystem has blocks claimed by another file.
5881 E2fsck now checks to see if the i_size field of a fast symlink is too
5882 big, and offers to clear the symlink if so.
5884 E2fsck now checks to see if i_size_high of special files is non-zero,
5885 and offers to clear i_size_high.
5887 Fix e2fsck's handling of incompatible journal flags so that the user
5888 has chance to abort, and then has the option to clear out the journal
5889 entirely. (Addresses Debian bug #98527.)
5891 Fixed a bug in fsck which could cause it to core dump if a mix of
5892 standard and non-standard device names are used in /etc/fstab.
5893 (Debian bug #100559)
5895 Fixed a bug in debugfs which caused read errors when copying a file to
5898 The debugfs set_super_value command can now modify the s_lastcheck field.
5900 Fixed a bug in lsattr and chattr which was accidentally introduced in
5901 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
5902 directories correctly because the change modified the layout of struct
5903 dirent to be incompatible with the libe2p shared library.
5905 Cleaned up the mke2fs manual page and included a discussion about why
5906 it's good to periodically check the filesystem even when journaling is
5912 Fix general gcc -Wall complaints.
5914 The types needed by the ext2 header files are now provided by
5915 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5917 Integers are now preferred to longs when trying to find a 32-bit type
5918 in ext2_types.h. Also, if linux/types.h has already been defined,
5919 don't try to redefine the types.
5921 Fixed make depend script so that it automatically corrects the
5922 pathname cleanups performed by make -M, so I don't have to fix them up
5925 Fixed the d_loaddump test case to be more robust, and not depend on
5928 Removed debugfs's dependence on pread(), which was accidentally
5929 intrudced in e2fsprogs 1.20
5931 Fixed a performance bug in the libext2fs's icount routine; the size
5932 estimate of the icount array was incorrectly being calculated.
5934 Removed use of the badblocks compatibility functions in the e2fsprogs
5937 Added paranoia code which protects against strange cases where /etc
5938 isn't on the root filesystem, or if /etc/mtab doesn't exist.
5940 The header file ext2_types.h is now installed.
5942 Autoconf is used to determine when we are on big-endian machines,
5943 instead of doing run-time tests, to save a few bytes of code.
5945 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5946 functions are no longer inline functions, which saves space and
5947 doesn't really cost any real performance.
5949 The ext2fs library no longer depends on the e2p library. (What need
5950 there was of it --- namely, fsetflags, was coded in-line).
5952 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5953 when the user is stupid and tries compiling the package using "make
5956 Miscellaneous code cleanups:
5957 * Added missing files from Makefile.in's SRCS file, so that
5958 their dependencies would be properly calculated.
5959 * Removed redundant code
5960 * Fixed comments in code
5961 * Removed no-longer unneeded argsused #pragma.
5964 E2fsprogs 1.20 (May 20, 2001)
5965 =============================
5967 Add support for replaying the ext3 journal purely in user mode,
5968 including handling the orphaned inode list. Used code contributed by
5969 Andreas Dilger, with bug fixes and the orphaned inode handling done
5972 The mke2fs and tune2fs programs can create or modify a filesystem to
5973 include an ext3 journal. Tune2fs also can be used to remove an ext3
5974 journal from a filesystem.
5976 E2fsck will now check for the existence of a linked list of orphan
5977 inodes in the superblock, and clear those inodes before starting the
5978 rest of the filesystem check (but after the journal playback).
5980 E2fsck now validates the file descriptor passed to the -C option,
5981 which saves against the completion bar getting written to an
5982 unexpected location, such as the disk being checked. (Debian
5983 bug/wishlist #55220)
5985 E2fsck will now bump the filesystem revision number from zero to one
5986 if any of the compatibility bits are set.
5988 Fixed a bug where a badly corrupted directory on a big endian system
5989 could cause e2fsck to die with a bus error. The
5990 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5991 the ext2 library now does alignment sanity checks on the rec_len field
5992 of the directory entry before using it.
5994 The ext2 library has been enhanced to make tune2fs safe to run on
5995 mounted filesystems. (Users could usually get away with using tune2fs
5996 on mounted filesystems before, but with the advent of ext3 and
5997 journaling, it became important to make tune2fs was *really* safe for
5998 use even when the filesystem being modified is mounted.) E2label is
5999 now implemented by tune2fs using an argv[0] dispatch, so that e2label
6000 is also now safe for use on mounted filesystems.
6002 Added a new program, e2image, which creates a backup of critical ext2
6003 filesystem data structures. The generated image file can be examined
6004 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
6005 the image file to help recover very badly damaged filesystems.
6007 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
6008 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
6009 large file when deciding whether or not the filesystem has large files.
6011 Fixed lsattr and chattr so that they work correctly on large files.
6012 (Fixes Debian bug #72690.)
6014 Removed limitation in get_device_size() which imposed a one terrabyte
6015 filesystem limitation. (Most 2.2 kernels still have a signed int
6016 problem which cause 1 TB block device limitation. Fortunately, the
6017 kernel patches to fix this are much easier than fixing the 2TB
6018 limitation in the kernel. :-)
6020 A max_mount_count of zero is now treated as if no mount count were
6021 set. (Previously, no mount count was indicated by using -1, and a
6022 mount count of zero caused e2fsck to always be run.)
6024 Mke2fs supports two new filesystem types largefile and largefile4.
6026 Mke2fs now adds some randomness in s_max_mount_count so that multiple
6027 filesystems won't be all checked at the same time under normal
6030 Fixed bug in the progress bar printing code which could cause e2fsck
6031 to core dump on an illegal filesystem.
6033 Fixed bug in fsck which could allow more than one instance of e2fsck
6034 to be printing a progress bar. (Debian bug #65267)
6036 Fsck using a UUID or a LABEL specifier will work even if devfs is
6037 compiled into the kernel and not mounted. If the pathnames in
6038 /proc/partitions are incorrect, fsck will search /dev for the correct
6039 device (using the new ext2fs_find_block_device library function).
6040 Fsck now also checks the RAID devices first so that they are properly
6041 found when they are in use. Support has also been added to support
6042 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
6044 Fixed a bug in fsck which caused it not deal properly with 16
6045 byte long filesystem labels.
6047 Fsck's -t option has been made a lot more flexible. The semantics for
6048 what happens if a comma-separated list to fsck has been regularized,
6049 and it is now possible to filter what filesystems will get checked
6050 based what is in the filesystem's fstab entry's option field. (Debian
6053 The dumpe2fs program can now print out the group description
6054 information in hex, and also prints the location of the superblock and
6055 block group descriptor for those block groups that have them.
6057 Mke2fs now clears the ext2 superblock before it starts creating a
6058 filesystem, so that the superblock magic number is only written if the
6059 filesystem creation process successfully completes.
6061 The debugfs program's stat command now pretty-prints the blocks used
6062 by an inode so that it's more compact and informative.
6064 The debugfs stats command now uses the same libe2p code (which is used
6065 by dumpe2fs) to print the superblock header information. This is more
6066 complete, and it avoids a bit of code duplication.
6068 Added a new debugfs command, set_super_value (ssv) which allows the
6069 user to set arbitrary superblock fields.
6071 Debugfs was extended to support inode numbers in hex (by prefixing
6072 them with 0x), and so that modify_inode can set the inode generation
6073 number. Also, there is now a new function command called logdump
6074 which will dump an ext3 journal.
6076 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
6079 Debugfs's dump command now stops immediately upon reporting a disk
6080 read error. (Fixed a bug in ext2fs_file_read library routine which
6081 caused debugfs not to stop.) (Debian bug #79163)
6083 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
6084 checked before /etc/mtab is used, since /proc/mounts is more likely to
6087 Added portability fixes for Solaris and Linux/ia64.
6089 Various manual pages were clarified and cleaned up. (Fixed debian
6090 bugs #63442, #67446, and #87216)
6096 The e2fsck message printer now supports %Iu and %Ig, which will print
6097 out the inode's user and group owners, respectively.
6099 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
6100 that no longer dependent on the system having the correct version of
6101 the kernel header files.
6103 Added a new function to libext2, ext2fs_find_block_device(), which
6104 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
6105 device given its device number.
6107 Added a new function to libext2, ext2fs_sync_device, which centralizes
6108 all of the places which might try to use the BLKFLSBUF or FDFLUSH
6109 ioctls (and usually failing to define them since the system header
6110 files don't usually do this for us, and we're trying to avoid usage of
6111 kernel include files now).
6113 Added new utility programs in tests/progs: random_exercise and
6114 hold_inode. They aren't built by default; they're useful for
6115 exercising ext3 filesystem code.
6117 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
6118 the filesystem close functions to only update the superblock, and to
6119 not touch the block group descriptors. Needed by tune2fs when
6120 modifying a mounted filesystem.
6122 Got rid of struct ext2fs_sb and replaced it with the standard struct
6123 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
6124 source (but not binary) compatibility of some users of the ext2
6125 library. Those applications should just simply do a global search and
6126 replace of struct ext2fs_sb with struct ext2_super_block, and include
6127 the new header file <ext2fs/ext2_fs.h> which defines it.
6129 The ino_t type has been renamed ext2_ino_t to protect applications
6130 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
6131 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
6132 unexpected ABI change.
6134 The Makefiles have been reworked so that "make check" can be run from
6135 the top-level Makefile.
6137 Fix general gcc -Wall complaints and removed dead code.
6139 Remove use of NOARGS, because we assume everyone does ANSI C these
6142 Added build-rpm script from sct.
6144 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
6147 New function ext2fs_flush_icache which must be called if the
6148 application program modifies the inode table blocks without going
6149 through ext2fs_write_inode() interface.
6151 New ext2fs_check_mount_point() function, which will return the mount
6152 point of a device if mounted.
6154 The io_channel abstraction now has an optional interface,
6155 io_channel_write_range, which allows specific byte ranges to be
6158 The unix_io IO channel now supports write-through caching, so that
6159 journal creation is more efficient.
6161 Added x86 assembly language routines to support byte swapping, to
6162 reduce executable size.
6164 Fixed bug in the utility program subst so that it's possible to
6165 replace a substitution variable with a zero-length string.
6167 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
6168 slipped into some of the problem number.
6170 E2fsprogs 1.19 (July 13, 2000)
6171 ==============================
6173 Release the resize2fs program since the timeout before it could
6174 be released under the GPL has finally expired.
6176 Add experimental support needed for the ext2 compression patches.
6177 This requires compiling e2fsprogs with the --enable-compression flag
6178 to the configure script.
6180 Added ext3 journalling support. E2fsck will run the journal (if
6181 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
6182 installed as a symlink to e2fsck. Fsck has been taught about ext3,
6183 and treats it the same as ext2 in terms of the progress bar logic.
6184 Dumpe2fs will display the superblock journaling information if the
6185 filesystem has a journal. The ext2 library will now permit opening an
6186 ext3 filesystem with the recovery flag set. This is necessary for
6187 on-line dump's to work correctly, but there may be issues with this
6188 working well since ext3 is much less agressive about syncing blocks to
6189 the filesystem, since they're safe on the journal.
6191 Tune2fs and e2fsck have been changed to allow the mount_count check to
6192 be disabled by setting max_mount_count to -1. (This was already
6193 supported by the kernel.)
6195 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
6196 are used for ext3 as well.
6198 Added internationalization support for e2fsprogs; must be enabled
6199 by passing --enable-nls to configure.
6201 Always use the provided ext2fs header files to insulate ourselves from
6202 kernel version changes. Which include files are used by e2fsprogs
6203 have also been cleaned up to improve portability.
6205 Limit the number of times that e2fsck updates the progress bar so that
6206 people who are booting using a 9600 baud console don't get swampped by
6209 Improved the loop detection algorithm in e2sck's pass #3 so that it is
6210 much, much faster for large filesystems with a large number of
6213 The memory footprint for e2fsck is now slightly smaller than before.
6215 E2fsck now checks if special devices have a non-zero size, and offers
6216 to clear the size field if it finds such an inode.
6218 E2fsck now checks if special devices have the append-only flag set,
6219 and offers to clear the inode.
6221 E2fsck now properly handles some "should never fail" cases during a
6222 bitmap copy in pass5.
6224 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
6226 E2fsck now calculates the correct location of the backup superblock in
6227 the case of filesystem blocksizes > 1k.
6229 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
6230 which normally didn't cause problems under most filesystem parameters,
6231 but could cause a valid superblock to be rejected in extreme cases.
6232 Other checks for validating superblock values were made more
6235 Added non-destructive write testing to the badblocks program, courtesy
6236 of David Beattie. The badblocks also now has an option to input the
6237 current set of bad blocks, so that known bad blocks are skipped to
6238 speed up the badblocks test. There is also a persistent rescan
6239 feature which causes badblocks to run until it has completed some
6240 number of passes without discovering any new bad blocks.
6242 Badblocks now checks to see if the device is mounted and refuses to do
6243 the tests involving writing to the device if it is mounted. Also,
6244 badblocks now allows the number of blocks to be checked to be
6245 defaulted to the size of the partition.
6247 Fixed a bug in fsck which didn't allow non-root users to be able to
6248 check filesystems if there were any LABEL= or UUID= entries in
6251 The Hurd doesn't support the filetype filesystem feature. The mke2fs
6252 program now makes sure that for the Hurd, the filestype feature is
6253 turned off. E2fsck will check to see if the filetype feature is
6254 turned on for Hurd filesystems, and offer to turn off the feature.
6256 Mke2fs now has a safety check to make sure the number of blocks do not
6257 exceed 32 bits even on a 64 bit platform.
6259 Really fixed a bug in fsck to allow "fsck -As" to run interactive
6260 fsck's. (For those people who like to do interactive fsck's in the
6263 Debugfs has a few new features: the rdump command, which will do a
6264 recursive dump of a directory and all of its contents, and the lcd
6265 command which does a local chdir (much like the ftp command of the
6266 same name). In addition, the debugfs program and the open_filesystem
6267 command now takes three new options: -b and -s, which allows the
6268 blocksize and superblock location to be specified, and the -c option
6269 which is used in catastrophic situations where the block group
6270 descriptors are corrupt. If the -c option is specified, debugfs will
6271 skip trying to read in the block and inode bitmaps.
6273 Debufs's lsdel command was fixed to handle bad blocks in the inode
6276 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
6279 General improvements in error messages
6281 - Mke2fs prints a sane error message if the partition size is zero
6282 (usually because the partition table wasn't reread by the
6283 kernel due to the partition being busy), instead of "invalid
6284 argument passed to ext2 library while initializing superblock".
6286 - Fsck now prints more self-explanatory message if an invalid UUID=
6287 or LABEL= specification is passed to it.
6289 UUID library changed to use the LGPL.
6291 Fixed a bug in the UUID library where very rapid calls to the
6292 time-based UUID generator could cause duplicate UUID's to be returned.
6293 This was not a problem for e2fsprogs, but it could be a problem for
6294 other users of the library.
6296 Make the UUID library more robust in the face of missing or an
6297 improper /dev/urandom or /dev/random files.
6299 Added some random portability fixes for Solaris.
6301 Some minor man page updates.
6303 Fixed a memory leak in the ss library.
6309 We now try to use lseek64 and open64 from the LFS if possible.
6311 The 3rd parameter in e2p's print_flags is now a flags word, instead of
6314 The mark and unmark bitmap functions now return the previous state of
6315 the bit that was being changed, which is useful for some speed
6318 The following functions have been added to enhance the badblocks list
6319 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
6320 ext2fs_badblocks_equal.
6322 The ext2 header files now have the latest journalling fields to the
6325 The ext2fs_mkdir function in libext2fs now properly backs out of error
6326 conditions robustly.
6328 Cleaned up makefiles:
6329 - to cleanly compile with the -j flag.
6330 - so distclean removes all generated files.
6331 - so in case of an error while installing header files, the make aborts.
6333 Fix test_script so that it works correctly when compiling in the
6336 The random UUID generation routine has been made slightly better in
6337 the case where /dev/random doesn't exist. (Use of randomly-based UUID
6338 is still not recommended if /dev/random doesn't exist, however; it's
6339 better to use the time/ethernet MAC address UUID in this case.)
6341 Clean up the build process so it's more friendly in case of missing
6344 The ext2fs header file can now be #include'd into C++ programs.
6346 The e2p.h header file is now installed.
6348 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
6352 E2fsprogs 1.18 (November 10, 1999)
6353 ==================================
6355 Fix a core dumping bug in e2fsck if an imagic inode is present or
6356 (more rarely) if the filesystem is badly corrupted enough that e2fsck
6357 has to restart pass 1 processing. E2fsck now closes the filesystem
6358 before freeing a large number of its data structures, so in the case
6359 of future memory faults, at least the fixed filesystem will be fully
6362 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
6363 imagic inode, it will offer to clear the imagic flag.
6365 E2fsck will now offer to clear the immutable flag on special files
6366 (device/socket/fifos) when running it in non-preen mode.
6368 E2fsck will now set the filetype when creating /lost+found, and when
6369 connected orphaned inodes to /lost+found.
6371 Debugfs's ncheck and icheck commands now handles the case where there
6372 are bad blocks in the inode table without bombing out.
6374 The badblocks list processing code has been made more efficiently for
6375 appending a large number of (ordered) badblocks to the badblocks list.
6377 Some minor man page updates.
6379 Fsck now allows interactive e2fsck's when using fsck -As (not a common
6380 mode, but some people like to do this in boot scripts for silly reasons).
6385 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
6386 with the problem code convention.
6388 The badblocks list regression test program has been updated to work
6389 with previously made API name changes.
6391 The ext2fs_free() command now uses the new badblocks API to avoid
6392 using the compatibility layer.
6394 Added new regression test cases; the run_e2fsck test script now
6395 supports the ability for a test case to run a prepratory command
6396 before running e2fsck.
6398 E2fsprogs 1.17 (October 26, 1999)
6399 =================================
6401 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
6404 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
6405 thus potentially causing problems if a binary UUID contained a NULL
6408 E2fsck now uses stricter checks for directory entries in pass 2:
6409 zero-length filenames are not allowed; neither are 8 byte long
6412 The debugfs "dirty" command now clears the filesystem valid bit.
6413 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
6414 bit in the in-core superblock image. The new functionality is more
6415 what the user expects, and is more useful.)
6417 Added a debugging hook to test parallel fsck; if the environment
6418 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
6419 will be checked in parallel when they normally would not be.
6424 Fixed some #ifdef's for compilation under the Hurd OS.
6426 Fixed minor W2K compatibility problems.
6428 Fixed some miscellaneous GCC warnings.
6431 E2fsprogs 1.16 (October 22, 1999)
6432 =================================
6434 Fixed a race condition bug in fsck; when printing a progress bar, if
6435 checking multiple filesystems in parallel, it was possible for fsck to
6436 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
6437 handler, which would cause it to terminate with a signal 10.
6439 E2fsck now properly handles filesystems that have the
6440 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
6441 filesystem into using or not using FILETYPE feature.
6443 E2fsck now properly handles filesystems that have the IMAGIC feature
6444 turned on (this is used on Linux AFS servers).
6446 The mke2fs program now creates filesystems that have the filetype and
6447 sparse_superblock features enabled by default, unless it is run on a
6448 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
6449 so there is now a new flag -O which allows the user to specify with
6450 which features she would like to create the filesystem; "mke2fs -O
6451 none" will create a filesystsem compatible with 2.0 kernels.
6453 The tune2fs program now has a -O option which allows the user to set
6454 and reset "safe" filesystem features. Currently, the only ones which
6455 allows to be modified are the filetype and sparse_superblock features.
6456 Note setting or clearing either feature will require running e2fsck on
6457 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
6458 requires that there is enough free space on the filesystem for the
6459 extra superblocks which will be created by e2fsck.)
6461 Debugfs can now set and print filesystem features in the superblock
6462 using the "features" command. Dumpe2fs will print out the complete
6463 set of features when listing the superblock.
6465 Dumpe2fs has new options -f (force) and -h (header-only).
6467 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
6468 message to come up. This could happen when decrementing or
6469 incrementing a link count could result in an overflow.
6471 Fixed a bug in e2fsck where the block count on the lost+found
6472 directory would not be properly incremented when the directory was
6473 expanded to the point where an indirect block needed to be allocated.
6475 E2fsck now makes some additional sanity checks on the superblock to
6476 avoid crashing or giving a memory allocation error if some of the
6477 values in the superblock are unresonable (but the superblock otherwise
6480 Fixed a bug in e2fsck where a very badly corrupted filesystem might
6481 require two passes to completely fix the filesystem. This happened if
6482 an inode claimed blocks that was part of the filesystem metadata
6483 (typically, when garbage was written into an inode table or indirect
6484 block, since this kind of filesystem corruption normally doesn't
6487 On the Alpha, glibc declares st_flags although it isn't actually used;
6488 the configure script was improved to detect this case so that
6489 e2fsprogs can avoid using the non-functional stat field.
6491 The manual pages were updated to use a more consistent formatting
6492 style consistent with standard Unix man pages. Mke2fs's man page
6493 added documentation for a few previously undocumented options.
6495 Fixed minor display bugs in tune2fs and mke2fs.
6500 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6502 Added features to parse and print feature strings into the e2p library.
6503 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6505 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6506 whose directory entries contain proper filetype information if the
6507 filesystem supports it.
6509 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6510 the directory entry filetype information. This is used to set the
6511 directory entry filetype information if the filesystem supports it.
6513 Fixed a bug in ext2fs_expand_dir() where the block count in a
6514 directory's inode would not be properly incremented when the directory
6515 was expanded to the point where an indirect block needed to be
6519 E2fsprogs 1.15 (July 18, 1999)
6520 ==============================
6522 Add configuration checks so that e2fsprogs will compile cleanly on
6523 Linux 2.3 kernels that have renamed i_version to i_generation.
6525 E2fsck now prints a progress/completion bar (and not just a simple
6526 spinner) if the -C0 option is requested or if it receives a SIGUSR1
6527 signal. Fsck will automatically manage the (potentially muliple)
6528 e2fsck processes to print completion bars if it is given a -C option,
6529 with the right thing happening if multiple filesystems are being
6530 checked in parallel.
6532 Mke2fs now has better automatic hueristics to determine the filesystem
6533 parameters to be used for a particular filesystem. Added a new option
6534 -T which allows the user to specify how the filesystem is to be used,
6535 which helps mke2fs do a better job selecting the filesystem parameters.
6537 Mke2fs now creates revision 1 filesystems by default, and with the
6538 sparse superblock feature enabled. The sparse superblock feature is
6539 not understood by Linux 2.0 kernels, so they will only allow read-only
6540 mounts of filesystems with this sparse superblocks.
6542 Fix bug where if /dev/null couldn't be opened (should never happen),
6543 e2fsck would hang in a tight loop.
6545 Make e2fsck handle the case where /lost+found isn't a directory.
6547 E2fsck now uses mallinfo if it exists to get accurate statistics about
6550 Fix bug in e2fsck where it wouldn't check to see if a disconnected
6551 inode had any problems before connecting it to /lost+found.
6553 Add check to e2fsck so it makes sure that total number of inodes in
6554 the filesystem is a sane number.
6556 Fix fencepost error when clearing an the end of the block bitmap which
6557 caused the last block in the bitmap not to get cleared.
6559 Cleaned up a number of messages in e2fsck:
6560 * The message "Group's #'s copy of the group descriptor..."
6561 was fixed so that the correct number would be displayed.
6562 * Added missing space in the "disk write-protected" error messsage
6563 * Cleaned up the error message printed when a non-interactive
6564 e2fsck needs to abort a check because the filesystem
6565 appears to be mounted.
6567 Added a new command-line utility, uuidgen, which will create and print
6570 Make debugfs's icheck command more robust by checking to make sure an
6571 inode has valid blocks before interarting over the inode's blocks.
6573 UUID generation now uses a random-based scheme whenever possible to
6574 prevent potential privacy problems.
6576 Man pages for all of the UUID functions in the lirbary were added.
6578 Fixed bug in fsck so it won't coredump if a filesystem not in
6579 /etc/fstab is given to it.
6581 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6582 that most of the other mount utilities understands.
6584 Mke2fs will make a filesystem even if it appears mounted if the force
6587 Dumpe2fs has new command-line options which allow a filesystem expert
6588 to specify the superblock and blocksize when opening a filesystem.
6589 This is mainly useful when examining the remains of a toasted
6592 The badblocks program has been updated to display correctly on disks
6593 with large block numbers.
6595 The badblocks program no longer gives spurious errors when errors
6596 occur on non-block boundaries, which is common if the blocksize is
6599 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6600 MKE2FS_SYNC environment variable is set. This is to work around a VM
6601 bug in the 2.0 kernel. I've heard a report that a RAID user was able
6602 to trigger it even using a 2.2 kernel, but hopefully it will not be
6603 needed for most Linux 2.2 users.
6605 Fixed miscellaneous documentation and man pages.
6610 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6611 in e2fsck's pass1.c really should have been static.
6613 The return value of the uuid_compare() function was changed to make it
6614 match with the convetions used by strcmp, memcmp, and Paul Leach's
6615 UUID sample document.
6617 The "make depend" process has now been made more automated; it now
6618 automatically word-wraps the dependencies, and only replaces source
6619 Makefile.in if there has been a change in the dependencies. Also, a
6620 top-level "make depend" now recurses through all the subdirectories
6623 The Makefile in .../util has been changed so that subst is built using
6624 the native C compiler during a cross-compilation, since the subst
6625 program is only used during the build process. Also add an explicit
6626 rule to build util/subst by cd'ing to the correct directory and
6629 The man directories are defined in terms mandir, so that the configure
6630 script can override the location of the manual pages.
6632 The config files have been updated to recognize new machine types for
6633 both the i386 and alpha families.
6635 Fsck has been modified so that it will accurately create an
6636 fsck_instance even when the noexecute flag is set. This allows for
6637 accurate debugging of the fsck pass structure. Also, when the verbose
6638 flag is given twice, fsck will print debugging information about when
6639 fsck is waiting for jobs to finish.
6642 E2fsprogs 1.14 (January 9, 1999)
6643 ================================
6645 Fix the fstab parsing code so that it can handle blank lines and
6646 comment characters. Also, missing pass numbers need to be treated as
6649 Fixed a bug in e2fsck where under some circumstances (when e2fsck
6650 needs to restart processing after fixing an egregious inconsistency)
6651 it would try to access already freed memory.
6653 E2fsck now prints non-printable characters in directory entries and
6654 pathnames using '^' and 'M-' notation.
6656 Fixed chattr so that it will ignore symbolic links when doing
6657 recursive descent traversals. For both chattr and lsattr, no longer
6658 print the version string unless the -V option is given.
6660 Allow the system administrator to directly specify the number of
6661 inodes desired in the filesystem, for some special cases where this is
6664 Fix portability problems so that e2fsprogs can be compiled under Linux
6665 1.2 systems and Solaris systems.
6667 Update the config.guess file with a more recent version that will
6668 identify newer Linux platforms.
6673 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6674 an inode number of zero is passed to them.
6676 E2fsprogs 1.13 (December 15, 1998)
6677 ==================================
6679 Fixed a bug in debugfs where an error messages weren't getting printed
6680 when the ext2 library routines to read inodes returned errors in the
6681 stat, cmri and rm commands.
6683 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6684 provided, it won't create an inode table smaller than the minimum
6685 number of inodes required for a proper ext2 filesystem.
6687 Fsck now parses the /etc/fstab file directly (instead of using
6688 getmntent()), so that it can distinguish between a missing pass number
6689 field and pass number field of zero. This caused problems for
6690 diskless workstations where all of the filesystems in /etc/fstab have
6691 an explicit pass number of zero, and fsck could not distinguish this
6692 from a /etc/fstab file with missing pass numbers.
6694 E2fsck will create a /lost+found directory if there isn't one in the
6695 filesystem, since it's safer to create the lost+found directory before
6698 Fixed e2fsck so that it would detect bogus immutable inodes which
6699 happen to be sockets and FIFO files, and offer to clear them.
6701 If a filesystem has multiple reasons why it needs to be checked, and
6702 one of the reasons is that it is uncleanly mounted, e2fsck will print
6703 that as the reason why the filesystem is being checked.
6705 Cleaned up the output routines of mke2fs so that it doesn't overflow
6706 an 80 column display when formating really big filesystems.
6708 Added a sanity check to e2fsck to make sure that file descriptors 0,
6709 1, 2 are open before opening the hard disk. This avoids a problem
6710 where a broken program might exec e2fsck with those file descriptors
6711 closed, which would cause disastrous results if the kernel returns a
6712 file descriptor for the block device which is also used by FILE *
6715 Fixed up the e2fsck progress reporting functions so that the values
6716 reliably reach 100% at the completion of all of the e2fsck passes.
6718 Fixed minor documentation bugs in man pages and usage messages.
6723 Fixed a number of lint warnings in the ext2fs library and potential
6724 portability problems from other OS's header files that might define
6725 CPP macros for names like "max" and "min".
6727 ext2fs_badblocks_list_add() has been made more efficient when it needs
6728 to grow the bad blocks list.
6730 Fixed a bug in e2fsck which caused it to dereference a freed pointer
6731 just before exiting.
6733 Fixed the substition process for generating the mk_cmds and compile_et
6734 scripts so that they will work outside of the build tree.
6736 Add sanity check to e2fsck so that if an internal routine
6737 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6738 and causing a core dump. This should never happen, but...
6740 E2fsprogs 1.12 (July 9, 1998)
6741 ==================================
6743 E2fsprogs now works with glibc (at least with the version shipped wtih
6744 RedHat 5.0). The ext2fs_llseek() function should now work even with
6745 i386 ELF shared libraries and if llseek() is not present. We also
6746 explicitly do a configure test to see if (a) llseek is in libc, and
6747 (b) if llseek is declared in the system header files. (See standard
6748 complaints about libc developers don't understand the concept of
6749 compatibility with previous versions of libc.)
6751 The ext2fs library now writes out the block group number in each of
6752 the superblock copies. This makes it easier to automatically
6753 determine the starting block group of the filesystem when the block
6754 group information is trashed.
6756 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6757 which means that e2fsprogs will ignore the high 8 bits of the
6758 directory entry's name_len field, so that it can be used for other
6761 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6762 E2fsprogs will now support filesystems with 64-bit sized files.
6764 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6766 Added new program "e2label", contributed by Andries Brouwer. E2label
6767 provides an easy-to-use interface to modify the filesystem label.
6769 Fixed bug so that lsattr -v works instead of producing a core dump.
6771 Fixed a minor bug in mke2fs so that all groups with bad superblock
6772 backup blocks are printed (not just the first one).
6774 Mke2fs will check the size of the device, and if the user specifies a
6775 filesystem size larger than the apparent size of the device it will
6776 print a warning message and ask if the user wants to proceed.
6778 E2fsck has a new option -C, which sends completion information to the
6779 specified file descriptor. For the most part, this is intended for
6780 programs to use, although -C 0 will print a spinning character to the
6781 stdout device, which may be useful for users who want to see something
6782 happening while e2fsck goes about its business.
6784 Fixed a bug in e2fsck which could cause a core dump when it needs to
6785 expand the /lost+found directory, and sometimes the bitmaps haven't
6786 been merged in. Also fixed a related bug where ext2fs_write_dir_block
6787 was used to write out a non-directory block. (Which would be bad on a
6788 non-Intel platform with byte swapping going on.)
6790 Fixed bug in e2fsck where it would print a "programming error" message
6791 instead of correctly identifying where a bad block was in used when
6792 the bad block was in a non-primary superblock or block group
6793 descriptor. Also fixed a related bug when sparse superblocks are in
6794 use and there is a bad block where a superblock or block group
6795 descriptor would have been in a group that doesn't include a
6798 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6799 the block group descriptor table is corrupt, it was possible to try to
6800 allocate a huge array, fail, and then abort e2fsck.
6801 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6802 and subsitutes reasonable values if the descriptors are obviously bogus.
6804 If e2fsck finds a device file which has the immutable flag set and the
6805 i_blocks beyond the normal device number are non-zero, e2fsck will
6806 offer to remove it, since it's probably caused by garbage in the inode
6809 When opening a filesystem, e2fsck specially checks for the EROFS error
6810 code, and prints a specific error message to the user which is more
6813 If the filesystem revision is too high, change the e2fsck to print
6814 that this is either because e2fsck is out of date, or because the
6815 superblock is corrupt.
6817 E2fsck now checks for directories that have duplicate '.' and '..'
6818 entries, and fixes this corruption.
6820 E2fsck no longer forces a sync of the filesystem (with attendant sleep
6821 calls) at all times. The ext2fs_flush() function now performs a sync
6822 only if it needed to write data blocks to disk.
6824 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6825 certain errors would not be properly reported.
6827 Updated and expanded a few points in the man pages which users
6828 complained wheren't explicit enough.
6830 Added special case byte-swapping code if compiling on the PowerPC, to
6831 accomodate the strange big-endian variant of the ext2 filesystem that
6832 was previously used on the PowerPC port.
6838 Removed C++ keywords from the ext2fs libraries so that it could be
6841 E2fsck's internal organization has now been massively reorganized so
6842 that pass*.c don't have any printf statements. Instead, all problems
6843 are reported through the fix_problem() abstraction interface. E2fsck
6844 has also been revamped so that it can be called as a library from a
6847 Added new fileio primitives in libext2fs for reading and writing
6848 files on an unmounted ext2 filesystem. This interface is now used by
6851 Added a new libext2fs function for mapping logical block numbers of
6852 a file to a physical block number.
6854 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6855 a block, zeros it, and updates the filesystem accounting records
6858 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6859 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
6861 The libext2fs functions now use a set of memory allocation wrapper
6862 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6863 instead of malloc, free, and resize. This makes it easier for us to
6864 be ported to strange environments where malloc, et. al. aren't
6865 necessarily available.
6867 Change the libext2fs fucntion to return ext2-specific error codes
6868 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6869 and depending on the existence of system error codes (such as EEXIST
6872 Renamed io.h to ext2_io.h to avoid collision with other OS's header
6875 Add protection against ext2_io.h and ext2fs.h being included multiple
6878 The types used for memory lengths, etc. have been made more portable.
6879 In generla, the code has been made 16-bit safe. Added Mark
6880 Habersack's contributed DOS disk i/o routines.
6882 Miscellaneous portability fixes, including not depending on char's
6885 The io_channel structure has a new element, app_data, which is
6886 initialized by the ext2fs routines to contain a copy of the filesystem
6889 ext2fs_check_directory()'s callback function may now return the error
6890 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6891 really do the checking, despite the presence of the callback function.
6894 E2fsprosg 1.11 (June 17, 1997)
6895 ==============================
6897 Fixed e2fsck to detect (previously ignored) conflicts between the
6898 superblock or block group descriptors and block bitmaps, inode
6899 bitmaps, and inode tables.
6901 Fixed bug in e2fsck so that when the message printed out when a block
6902 or inode bitmap conflicts with other data, it has the correct group
6905 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6906 to badblocks. This meant that not all of the filesystem was being
6907 tested for bad blocks!
6909 Fixed an array boundary overrun case which cropped up in
6910 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
6913 Adjusted the number of columns printed by mke2fs when displaying the
6914 superblock backups to avoid running over 80 columns when making a
6915 really big filesystem.
6917 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6918 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6919 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6924 Fixed install rule in lib/ss so that ss_err.h is actually getting
6927 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6928 bassed back to the caller.
6930 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6931 setting the current inode number (which meant this function wasn't
6934 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6935 blocks in the bitmap when increasing the size of the bitmap.
6937 Changed the initial number of blocks allocated by ext2fs_init_dblist()
6938 to be more realistic.
6940 Added a new function ext2fs_allocate_group_table, which sets up the
6941 group descriptor information (and allocates inode and block bitmaps,
6942 and inode tables for a particular group). The function was created by
6943 factoring out code form ext2fs_allocate_tables().
6945 Added a new function ext2fs_move_blocks which takes a bitmap of the
6946 blocks to be moved, and moves them to another location on the
6949 Make the unix_io channel's io_channel_flush implementation calls sync()
6950 to to flush the kernel buffers to disk.
6952 Added a new function ext2fs_dblist_count returns the number of
6953 directory blocks in dblist.
6956 E2fsprogs 1.10 (April 24, 1997)
6957 ===============================
6959 Mke2fs once again defaults to creating revision #0 filesystems, since
6960 people were complaining about breaking compatibility with 1.2 kernels.
6961 Warning messages were added to the mke2fs and tune2fs man pages that
6962 the sparse superblock option isn't supported by most kernels yet (1.2
6963 and 2.0 both don't support parse superblocks.)
6965 Added new flag to mke2fs, -R <raid options>, which allows the user to
6966 tell mke2fs about the RAID configuration of the filesystem. Currently
6967 the only supported raid option is "stride" which specifies the width
6970 Fixed bug in e2fsck where pass1b would bomb out if there were any
6971 blocks marked bad in the inode table.
6973 Fixed rare bug in mke2fs where if the user had a very unlucky number
6974 of blocks in a filesystem (probability less than .002) the resulting
6975 filesystem would be corrupt in the last block group.
6977 Fixed bug where if e2fsck tried to allocate a block to fix a
6978 filesystem corruption problem and the filesystem had no free blocks,
6979 ext2fs_new_block() would loop forever.
6981 The configure script now checks explicitly to see if "-static" works,
6982 since that can't be assumed to be true --- RedHat doesn't install
6983 libc-static by default.
6985 Fixed bug in libext2's block iterator functions where under some
6986 cirmcustances, file with holes would cause the bcount parameter to the
6987 callback function to be incorrect. This bug didn't affect any of
6988 e2fsprogs programs, but it was discovered by Paul Mackerras, the
6989 author of the PPC boot loader.
6991 Removed use of static variables to store the inode cache in libext2fs.
6992 This caused problems if more than one filesystem was accessed via
6993 libext2fs (static variables in libraries are generally a bad idea).
6994 Again, this didn't affect e2fsprogs programs, but it was discovered by
6997 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6998 will compile cleanly with 1.2.13 kernels (even with a.out shared
7004 Added new functions to duplicate an ext2 filesystem handle, and its
7005 associated substructure. New functions: ext2fs_dup_handle(),
7006 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
7007 Other structures, such as the io_channel and the inode_cache, now have
7008 a ref count so that they only get freed when they are no longer used
7009 by any filesystem handle. (These functions were added as part of the
7010 development effort for an ext2 resizer).
7012 E2fsprogs 1.09 (April 14, 1997)
7013 ===============================
7015 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
7016 accidentally introduced in the 1.08 release. The overhead calculation
7017 was accidentally removed, which caused ext2fs_initialize() to not
7018 notice when the filesystem size needed to be adjusted down because
7019 there wasn't enough space in the last block group.
7021 Fixed bug in version parsing library routine; it was always parsing
7022 the library version string, instead of using the passed-in string.
7024 Clarified chattr man page.
7026 E2fsprogs 1.08 (April 10, 1997)
7027 ===============================
7029 E2fsck 1.07 was very slow when checking very large filesystems with a
7030 lot of files that had hard links (i.e., news spools). This was fixed
7031 by seriously revamping the icount abstraction. Added a formal test
7032 suite for the icount abstraction.
7034 Debugfs now has a "-l" option to the "ls" command, which lists the
7035 inode number, permissions, owner, group, size, and name of the files
7038 Fix a bug in e2fsck where when a directory had its blocks moved to
7039 another location during the pass 1b processing, the directory block
7040 list wasn't updated, so pass 2 wouldn't check (and correct) the
7041 correct directory block.
7043 E2fsck will now treat inodes which contain blocks which are claimed by
7044 the filesystem metadata by treating them as multiply claimed blocks.
7045 This way, the data in those blocks can be copied to a new block during
7046 the pass 1b--1d processing.
7048 E2fsck will attempt to determine the correct superblock number and
7049 display it in the diagnostic and warning messages if possible.
7051 Add support for a new (incompatible) feature, "sparse_super". This
7052 feature reduces the number of blocks which contain copies of backup
7053 superblocks and block group descriptors. (It is only an incompatible
7054 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
7055 support a new -s option; e2fsck will recognize filesystems built with
7056 this feature turned on.
7058 E2fsck now checks the library to make sure is the correct version,
7059 using new library functions. (This helps to diagnose incorrectly
7060 installed e2fsprogs distributions.)
7062 Dumpe2fs now prints more information; its now prints the the
7063 filesystem revision number, the filesystem sparse_super feature (if
7064 present), the block ranges for each block group, and the offset from
7065 the beginning of the block group.
7067 Mke2fs now distributes the inode and block bitmap blok so that the
7068 won't be concentrated in one or two disks in RAID/striping setups.
7069 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
7070 choose the largest blocks per group that be chosen. (For 2k blocks,
7071 you can have up to 16384 blocks/group; for 4k blocks, you can have up
7072 to 32768 blocks/group.) Previously mke2fs would not allow
7073 specification of more than 8192 blocks per group, even if you were
7074 using a 2k or 4k block group.
7079 Added a new function ext2fs_create_icount2() which takes a "hint"
7080 argument. This hint argument presets the icount array with the list
7081 of inodes which actually need to be in the icount array. This really
7082 helps to speed up e2fsck.
7084 Added a new function ext2fs_icount_validate() which checks the rep
7085 invariant for the icount structure. This is used mostly for testing.
7087 The error mesasage given when a bad inode number is passed to
7088 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
7089 EXT2FS_UNMARK_ERROR).
7091 Added a new function ext2fs_set_dir_block which sets the block of a
7092 dblist entry, given the directory inode and blockcnt.
7094 Added a new function ext2fs_get_library_version() which returns the
7095 current library version, and ext2fs_parse_version_string() which
7096 returns a version number based on a e2fsprogs version string.
7098 The icount functions will return EINVAL if the passed in inode number
7101 E2fsprogs 1.07 (March 9, 1997)
7102 ==============================
7104 E2fsck is now uses much less memory when checking really large
7105 filesystems (or rather, filesystems with a large number of inodes).
7106 Previously a filesystem with 1 million inodes required 4 megabytes of
7107 memory to store inode count statistics; that storage requirement has
7108 now been reduced to roughly half a megabyte.
7110 E2fsck can now properly deal with bad blocks appearing inside the
7111 inode table. Instead of trying to relocate the inode table (which
7112 often failed because there wasn't enough space), the inodes in the bad
7113 block are marked as in use.
7115 E2fsck will automatically try to use the backup superblocks if the
7116 primary superblocks have a bad magic number or have missing meta-data
7117 blocks (or meta-data blocks which are out of range).
7119 E2fsck's pass 3 has been made more efficient; most noticeable on
7120 filesystems with a very large number of directories.
7122 Completely revamped e2fsck's system of printing problem reports. It
7123 is now table driven, to make them more easily customizeable and
7124 extendable. Error messages which can be printed out during preen mode
7125 are now one line long.
7127 Fixed e2fsck's filesystem swapping code so that it won't try to swap
7128 fast symbolic links or deleted files.
7130 Fixed e2fsck core dumping when fixing a filesystem which has no
7131 directories (not even a root directory).
7133 Added a check to e2fsck to make sure that the length of every
7134 directory entry is a multiple of 4 (since the kernel complains if it
7137 Added a check to e2fsck to make sure that a directory entry isn't a
7138 link to the root directory, since that isn't allowed.
7140 Added a check to e2fsk to now make sure the '.' and '..' directory
7141 entries are null terminated, since the 2.0 kernel requires it.
7143 Added check to write_bitmaps() to make sure the superblock doesn't get
7144 trashed if the inode or block bitmap is marked as being block zero.
7146 Added checking of the new feature set fields in the superblock, to
7147 avoid dealing with new filesystem features that this package wasn't
7150 Fixed a fencepost error in ext2fs_new_block() which would occasionally
7151 try to allocate a block beyond the end of a filesystem.
7153 When the UUID library picks a random IEEE 802 address (because it
7154 can't find one from a network card), it sets the multicast bit, to
7155 avoid conflicting with a legitimate IEEE 802 address.
7157 Mke2fs now sets the root directory's owner to be the real uid of the
7158 user running mke2fs. If the real uid is non-zero, it also sets
7159 the group ownership of the root directory to be the real group-id of
7160 the user running mke2fs.
7162 Mke2fs now has more intelligent error checking when it is given a
7163 non-existent device.
7165 When badblocks is given the -vv option, it now updates the block that
7166 it is currently testing on every block.
7168 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
7169 currently correctly if PATH wasn't already set.
7171 Shared libraries now built with dependencies. This allows the shared
7172 library files to be used with dlopen(); it also makes the transition
7173 to libc 6 easier, since ld.so can tell which libc a particular shared
7174 library expects to use.
7179 Added new abstraction (defined in dblist.c) for maintaining a list of
7180 blocks which belongs to directories. This is used in e2fsck and other
7181 programs which need to iterate over all directories.
7183 Added new functions which test to see if a contiguous range of blocks
7184 (or inodes) are available. (ext2fs_*_bitmap_range).
7186 Added new function (ext2_inode_has_valid_blocks) which returns true if
7187 an inode has valid blocks. (moved from e2fsck code).
7189 Added new function (ext2fs_allocate_tables) which allocates the
7190 meta-data blocks as part of initializing a filesystem. (moved from
7193 Added a new I/O manager for testing purposes. It will either allow a
7194 program to intercept I/O requests, or print debugging messages to
7195 trace the activity of a program using the I/O manager.
7197 The badblocks_list functions now store the bad blocks in a sorted
7198 order, and use a binary search to speed up badblocks_list_test.
7200 The inode scan function ext2fs_get_next_inode() may now return a soft
7201 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
7202 those cases where part of an inode table is missing or there is a bad
7203 block in the inode table.
7205 Added a new function (ext2fs_block_iterate2) which adds new arguments to
7206 the callback function to return a pointer (block and offset) to the
7207 reference of the block.
7209 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
7210 application to jump to a particular block group while doing an inode
7213 The badblocks list functions were renamed from badblocks_* to
7214 ext2fs_badblocks_*. Backwards compatibility functions are available
7215 for now, but programs should be modified to use the new interface.
7217 Some of the library functions were reorganized into separate files to
7218 reduce the size of some programs which statically link against the
7221 Put in some miscellaneous fixes for the Alpha platform.
7224 E2fsprogs 1.06 (October 7, 1996)
7225 ================================
7227 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
7228 smash the backup copies in ext2fs_close(). (The problem was that when
7229 e2fsck -p discovered the problem, while it was closing the filesystem
7230 and exiting, it was also blowing away the backup superblocks on the
7231 disk, which was less than friendly.) We now make it the case that we
7232 only write out the backup superblock and the back block descriptors if
7233 the filesystem is completely free from problems.
7235 Fixed a bug in block_interate in the lib/ext2fs library which caused
7236 e2fsck to fail on GNU Hurd-created filesystems.
7238 Add support for Linux/FT's bootloader, which actually uses
7239 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
7242 Add support for the "A" (no atime update) attribute. (Note: this
7243 attribute is not yet in production kernels.)
7245 The test suite is not automatically run when doing a "make all" from
7246 the top level directory. Users should manually run "make check" if
7247 they wish to run the test suite.
7249 Upon a preenhalt(), make the printed message more explicit that
7250 running e2fsck "MANAULLY" means without the -p or -a options.
7252 In e2fsck, if a disconnected inode is zero-length, offer to clear it
7253 instead of offering to connect it to lost+found.
7255 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
7256 e2fsck to be run over it, change e2fsck to explicitly display this
7259 For dumpe2fs and e2fsck, cause the -V option to print out which
7260 version of the ext2fs library is actually getting used. (This will
7261 help detect mismatches of using a 1.06 utility with a 1.05 library,
7267 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
7268 the naming convention.
7270 In ext2fs_initialize(), make sure the description for the inode bitmap
7271 is correctly initialize.
7273 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
7275 E2fsprogs 1.05 (September 7, 1996)
7276 ==================================
7278 Add support for new fields in the ext2 superblock --- volume name,
7279 volume UUID, and last mounted field. Dumpe2fs displays these fields,
7280 tune2fs and mke2fs allows you to set them. E2fsck will automatically
7281 generate a UUID for those volumes that don't have them.
7283 Put in support for e2fsck to recognize HURD specific ext2 features ---
7284 most notably, the translator block. The e2fsprogs tools will now use
7285 the creator_os field in the superblock to correctly handle different
7286 OS-specific variants of the ext2 filesystem.
7288 E2fsck now fixes inodes which have a the deletion time set, but which
7289 have a non-zero i_link_count field by offering to clear the deletion
7290 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
7291 ext2 kernel behavior) and offered to unlink the file.
7293 If e2fsck sets the clean bit, but nothing else, set the exit code
7294 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
7295 set the filesystem valid bit when it was previously cleared. :-) This
7296 was needed to make the HURD fsck driver happy.
7298 If the user refuses to attach an unattached inode, e2fsck will no
7299 longer set the inode's link count. Otherwise, the inode would end up
7300 getting marked as unused, which might cause loss of data later.
7302 Make the message issued by e2fsck when the superblock is corrupt less
7303 confusing for users. It now mentions that another reason for the
7304 "corrupt superblock" message might be that the partition might not be
7305 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
7307 Make the libext2 library more robuest so that e2fsck won't coredump on
7308 an illegal superblock where the blocksize is zero. (f_crashdisk is
7311 By default, create filesystems where the default checkinterval is 6
7312 months (180 days). Linux servers can be robust enough that 20 reboots
7313 can be a long, long time.
7315 Added configure flag --enable-old-bitops, which forces the bitops to
7316 use the old (native) bitmask operations. By default on the sparc
7317 platform, the standard ext2 bit ordering is now used.
7319 Added a new feature to e2fsck to byte-swap filesystems; this can be
7320 used to convert old m68k filesystems to use the standard byte-order
7321 storage for the superblock, inodes, and directory blocks. This
7322 function is invoked by using the '-s' option to e2fsck.
7324 Debugfs's "dump" command has been enhanced so that it writes out the
7325 exact size of the file so that the nulls at the end of the file are
7326 eliminated. The command also accept a new "-p" option which will
7327 attempt preserve to preserve the ownernship, permissions, and
7328 file modification/access times.
7330 Debugfs has two new options, -f and -R. The -R option allows the user
7331 to execute a single debugfs command from the command line. The -f
7332 option allows the user to specify a "command file" containing debugfs
7333 commands which will get executed.
7335 Dumpe2fs now pretty prints the check interval, instead of just
7336 printing the check interval as a number of seconds.
7338 Fix bugs in debugfs: the params command when no filesystem is opened
7339 no longer causes a core dump. It is now possible to unlink a file
7340 when a pathame containing a '/' is specified.
7342 Tune2fs has a new -C option which sets the number of times the
7343 filesystem has been mounted.
7345 Fix the chattr '-v' option so that it actually works. Chattr was
7346 being buggy about the -v option parsing.
7351 The directory lib/uuid contains a set of library routines to generate
7352 DCE compatible UUIDs.
7354 Extended ext2fs_namei() to handle symbolic links. Added new function
7355 ext2fs_nami_follow() which will follow last symbolic link in the case
7356 where the pathname points to a sym link.
7358 The ext2fs_block_iterate function will now return the HURD translator
7359 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
7360 iterator to return data blocks only. The ext2fs.h file now defines
7361 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
7362 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
7363 count field of the iterator callback function.
7365 The test script driver now takes an optional second argument, which is
7366 the test case to be run. This allows you to run a test case without
7367 needing to run the entire test suite.
7369 On Linux ELF systems, install the .so files in the correct places
7370 (/usr/lib). The .so files must be stored in the same directory as the
7373 Fixed miscellaneous HURD compilation issues with header file being
7374 included in the right order.
7376 Fixed debugfs so that it resets optind to zero, not one, since setting
7377 optind to zero is more correct.
7380 E2fsprogs 1.04 (May 16, 1996)
7381 =============================
7383 First "official" (1.03 was a limited release only) to support building
7384 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
7387 This package includes a RPM specs file, that it can be built using the
7388 RedHat Package Manager.
7390 E2fsck now prints a hint that if there are lots of incorrectly located
7391 inode bitmaps, block bitmaps, and inode table blocks, the user might
7392 want to try using e2fsck -b 8193 first, to see if that fares any
7395 For ext2 filesystem written with the hurd, debugfs will now print out
7396 the translator field when printing an inode structure.
7398 Lots of miscellaneous linking/installation cleanups:
7400 Libraries are now linked using a relative pathname, instead of
7401 relying on -L working correct. It doesn't, in many cases, including
7402 current versions of GNU ld. This guarantees that the build tree is
7403 linking with the right libraries, instead of the ones installed in
7406 Header files, man pages, and the et/ss shell scripts are now
7407 generated using a custom substitution script, instead of relying on
7408 the configure script. This prevents needless recompilation of
7409 files; in addition, the custom substitution script is much faster.
7411 e2fsck may now be linked dynamically, by using the
7412 --enable-dynamic-e2fsck flag to configure. This is not recommended,
7413 since it increases e2fsck's dependence on other files, but some
7414 people need to save disk space, and other critical programs on their
7415 systems were being linked dynamically anyway.
7417 Programs such as fsck which didn't need to be linked against
7418 libext2fs (or mke2fs which didn't need to be linked against libe2p)
7419 only link against libraries they actually need. Otherwise, those
7420 programs would require the presense of libraries that otherwise
7421 could be removed from a rescuse diskette.
7423 The ss include files are now installed correctly so they can
7424 actually be used by another package.
7426 If the profiling libraries are built, they are now installed on a
7427 "make install-libs".
7430 E2fsprogs 1.03 (March 27, 1996)
7431 ===============================
7433 Change the m68k bit numbering for bitmasks to match the bit numbering
7434 used by all other ext2 implementations. (This change was requested by
7435 the m68k kernel development team.)
7437 Support (in-development) filesystem format revision which supports
7438 (among other things) dynamically sized inodes.
7440 Fixed a bug in the ext2 library so that an intelligent error is
7441 returned if mke2fs is run with a ridiculously small number of blocks
7444 Fixed a bug in the ext2 library which required that the device be
7445 openable in read/write mode in order to determine its size. This
7446 caused e2fsck -n to require read/write access when it was not
7447 previously necessary.
7449 Fixed a bug in e2fsck which casued it to occasionally fail the test
7450 suite depending on which version of the floating point library it was
7453 Fixed a bug in e2fsck so that it now halts with a fatal error when
7454 certain superblock consistency checks fail. Previously it continued
7455 running e2fsck, with some potential confusing/damaging consequences.
7457 Added new flag to fsck which allows the root to be checked in parallel
7458 with other filesytems. This is not the safest thing in the world to
7459 do, but some system administrators really wanted it.
7461 Fixed -Wall flames in lib/ss.
7464 E2fsprogs 1.02 (January 16, 1996)
7465 =================================
7467 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
7469 Change e2fsck to print statistics of how many non-contiguous files are
7470 on the system. Note that a file which is larger than 8k blocks, it is
7471 guaranteed to be non-contiguous.
7473 In mke2fs, print a warning message if a user tries to format a whole
7474 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
7475 whole disk, the -F (force) option forces mke2fs to format a whole disk
7478 Fix a bug in fsck where in some cases it might start checking
7479 partitions in the next pass before it finishes checking partitions in
7480 the current pass. This still won't cause two partitions on the same
7481 disk will be checked, so it's rarely a problem in real life.
7483 Patch lsattr so that it won't hang when checking a named pipe.
7485 Minor compilation fixes:
7486 * Fix the order of libraries that were linked in debugfs.
7487 * Allow the sources to be compiled with -ansi turned on.
