1 de2fsprogs 1.36-WIP (January 9, 2005)
2 ====================================
4 All of the patches that were applied to Fedore Core 3's
5 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
6 lot of bug fixes first. Users of Fedora Core 3 are strongly
7 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
9 Add support for filesystem with the online resizing via resize inode
10 feature. Fixed numerous bugs from the Fedora patches. The Fedora
11 patches also didn't bother to do any consistency checking on the
12 resize inode, or add any tests to the regression test suite. The "-R
13 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
14 being listed in mke2fs's usage message. All of these shortcomings
17 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
18 program. In order to do this, the user must run the commands:
20 debugfs -w /dev/hdXXX -R "features ^resize_inode
23 Optionally, the ext2prepare command can be used to re-enable online
24 resizing after the filesystem has been fixed.
26 The fsck program will now accept an optional filedescriptor argument
27 to the -C option. (The Fedora version of this patch would sometimes
28 cause fsck to ignore a parameter on fsck's command line in some rare
31 Badblocks will now correctly display block numbers greater than
32 999,999,999 in its progress display.
34 The tune2fs program will not allow the user from setting a ridiculous
35 number of reserved blocks which would cause e2fsck to assume the
36 superblock was corrupt. E2fsck's standards for what is a ridiculous
37 number of reserved block has also been relaxed to 50% of the blocks in
40 The blkid library will return vfat in preference to msdos, and ext3 in
41 preference to ext2 (if the journalling flag is set) so that mount will
42 do the right thing. (Addresses Debian bug #287455)
44 Mke2fs will now use the -E option for extended options; the old -R
45 (raid options) option is still accepted for backwards compatibility.
46 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
48 Mke2fs will now accept a size in megabytes, gigabytes, and other units
49 (via "32m" or "4g" on the command line) if the user finds this more
50 convenient than specifying a block count.
52 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
53 cache conherency problem.
55 Debugfs now supports a new command, set_inode_field, which allows a
56 user to manually set a specific inode field more conveniently, as well
57 as set entries in the indirect block map.
59 Debugfs's set_super_value command has been enhanced so that the user
60 can set most superblock fields, including the date/time fields and
61 some of the more newsly added superblock fields.
63 E2fsprogs programs now accept an offset to be passed to the file
64 specifiers, via the syntax: "/tmp/test.img?offset=1024".
66 E2fsprogs programs will now accept blocksizes up to 65536; kernel
67 support on the x86 doesn't exist for now, but it can be useful on
68 other architectures with page sizes greater than 4k.
70 Fix bug in debugfs where kill_file would lead to errors when deleting
71 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
73 Fix bug in the blkid library when detecting the ocfs1 filesystem
75 Remove obsolete EVMS 1.x and a.out DLL support.
77 E2fsck will attempt to recover from a journal containing illegal blocks.
79 Fixed two potential ordering constraint problems in e2fsck which might
80 cause the filesystem to be corrupted if e2fsck is interrupted during a
81 (extremely narrow) race window. Thanks to Junfeng Yang from the
82 Stanford Metacompilation group for pointing this out.
84 Fixed bug in e2fsck where it would not accurately detect whether or
85 not the system is running on adaptor if the ACPI device representing
86 the AC adapter didn't correspond to the what was used on IBM
89 Change e2fsck to accept directories greater than 32MB.
91 Fix e2fsck so that a checkinterval of zero disables a time-based check
94 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
95 to the PAGER environment variable. (Addresses Debian Bug #239547)
97 Tune2fs will not mark rewrite the superblock if the feature bitmasks
100 The debugfs program will set the filetype information when creating a
103 Add debugfs -d option to use a separate source of data blocks when
104 reading from an e2image file.
106 Add e2image -I option which allows the e2image metadata to be
107 installed into a filesystem.
109 Fixed bug in the badblocks program which caused "done" to always
110 appear in english even when a translation was available. (Addresses
113 The blkid program has a new option -o which controls the output format
114 of the blkid program; this is makes blkid more convenient to use in
117 Fix a minor bug in uuid library, which was not using the full 14 bits
118 of clock sequence when generating UUID's.
120 Fix a Y8.8888K problem in the uuid library.
122 Logsave now creates a new session id for itself to avoid getting
123 killed by init whan transitioning between init levels.
125 Change the licensing of the UUID library to be the 3-clause BSD-style
126 license; this allows Apple to use the uuid library in Darwin.
128 Add ocfs and ocfs2 probe support into the blkid library.
130 Fix a memory and file descriptor leak in the blkid library.
132 The blkid library will revalidate the device if the system time is
133 earlier than last verification time of the device, since that
134 indicates that the system time is probably nottrustworthy.
136 The blkid library will override the default location of the blkid.tab
137 file by the BLKID_FILE environment variable, if it is available.
139 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
141 Add various portability fixes for lame new versions of glibc, Darwin
142 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
143 Bugs #239934, #264630, #269044, #255589, #289133)
145 Add support for Windows 9x/NT under Cygwin.
147 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
148 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
150 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
152 Update the rpm spec files so that it works better with Fedora core 2
155 Fixed various Debian packaging issues (see debian/changelog). In
156 particular, fixed the Debian initrd scripts. (#241183, #248050,
163 Fixed various gcc -Wall warnings.
165 The uuid library now has new functions uuid_unparse_upper() and
166 uuid_unparse_lower() which forces the case of the hex digits to be
167 upper case, or lower case.
169 The build process has been speeded up by enhancing the subst program
170 to update the modtime on the generated files even when the generated
173 The uuid library now uses C99 stdint.h types instead of custom types.
175 Updated config.guess and config.sub with newer versions from the FSF.
177 Removed out of date .cvsignore files from the source distribution.
179 The ext2fs_unlink() function will return an error if both the name and
180 inode number are unspecified, to avoid doing something surprising
181 (such as unconditionally deleting the first directory entry).
182 Directory entries are now deleted by coalescing them with the previous
183 directory entry if possible, to avoid directory fragmentation. This
184 is not an issue with the e2fsprogs suite, but may be a problem for
185 some of the users of libext2fs, such as e2tools.
187 Add support for version numbers of the form "1.36-rc1".
189 Fix build of mke2fs.static.
191 The test_io mechanism can now abort after n reads or writes to a
192 particular block. The block is specified by TEST_IO_BLOCK environment
193 variable, and the read/write count by the TEST_IO_READ_ABORT and
194 TEST_IO_WRITE_ABORT environment variables. The block data is now only
195 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
197 UUID_DEFINE() in the uuid library now creates a static variable, with
198 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
199 be used in header files.
201 Add support for the install-strip and install-shlibs-strip targets, as
202 suggested by the GNU coding guielines. "make install" no longer
203 strips the binaries which are installed.
205 Use Linux-kernel-style makefile output so it is easier to see compiler
208 Update gettext files to version 0.14.1.
210 Update to use autoconf 2.5x.
212 Improved support for compiling e2fsprogs under dietlibc.
215 E2fsprogs 1.35 (February 28, 2004)
216 ==================================
218 E2fsck has a new -k option, which in conjunction with the -c options,
219 preserves the existing badblocks list.
221 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
223 E2fsprogs will now deal correctly with symlinks that contain
224 extended attribute information, which can be created using SE Linux.
225 (Addresses Debian Bug #232328)
227 Remove a double longjump into an invalid stack frame bug in e2fsck.
228 (This was during an abort sequence, which normally worked on Linux and
229 caused a core dump on other operating systems.)
231 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
232 (the NLS library will replace "" with the .po header information).
234 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
235 dump due to a division by zero error. (Addresses Debian bug #207082)
237 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
238 when reconnecting a directory requires creating a lost+found
239 directory. (Addresses Debian bug #219640).
241 Fixed a bug where e2fsck would bomb out if a journal needed to be
242 replayed when using an alternate superblock.
244 E2fsck will give an extra grace period before actually forcing a check
245 if the laptop is running on battery. The next time fsck runs while
246 the system is on the AC mains, or after the grace period is exceeded,
247 the filesystem will be checked. (Addresses Debian bug #205177)
249 E2fsck will inform the user when there are 5 or fewer mounts before a
250 filesystem check will be forced. (Addresses Debian bug #157194)
252 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
253 We now correctly handle the case where there is an overlap between a
254 block group descriptor or a superblock and a bad block indirect block.
255 In the case where the indirect block is corrupted, we now suggest
258 Fix byte swap bugs in e2fsck that caused the journal backup location
259 in the superblock and symlinks created by SE Linux to be cleared
260 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
262 E2fsck -c now replaces the current list of bad blocks with the ones
265 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
266 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
268 Fix a potential bug in e2fsck which could cause it to core dump when
269 trying to print the location of the backup superblock.
271 Protect against a potential core dump in e2fsck when printing a
272 message about backup superblocks.
274 Add support for backing up the journal inode location in the
275 superblock. E2fsck will automatically save the journal information in
276 the superblock if it is not there already, and will use it if the
277 journal inode appears to be corrupted. ext2fs_add_journal_inode()
278 will also save the backup information, so that new filesystems created
279 by mke2fs and filesystems that have journals added via tune2fs will
280 also have journal location written to the superblock as well.
281 Debugfs's logdump command has been enhanced so that it can use the
282 journal information in the superblock.
284 E2fsck will now update all superblocks when moving the journal inode.
286 Shrink the size of the e2fsck executable by moving some initialized
287 variables to the BSS segment.
289 E2fsck will avoid printing the ^A and ^B characters which bracket the
290 progress bar when stdout and stdin are a tty device instead of a pipe
291 to another program. (Addresses Debian bug #204137)
293 Debugfs's mkdir command will automatically expand the directory if
294 necessary. (Addresses Debian Bug: #217892)
296 Fixed a bug in debugfs so that copying a file from /dev/null uses the
297 correct mode bits. (Addresses Debian Bug: #217456)
299 If the environment variables DEBUFS_PAGER and PAGER are not set,
300 debugfs now searches for the appropriate pager to use, beginning with
301 /usr/bin/pager, and then falling back to 'more' and 'less'.
302 (Addresses Debian bug #221977)
304 Debugfs will now support 2.6 device numbers where the major or minor
305 number may be larger than 255. (Addresses Sourceforge bug #865289)
307 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
309 Chattr now stops processing options when it sees '--'. (Addresses
312 Fix regression tests so they work correctly when e2fsprogs is compiled
313 with configure --disable-htree.
315 Fix bug in uuid library when there is no network card and the library
316 is generating a time-based uuid. The random MAC address was not
317 correctly generated to be a multicast address.
319 Add compile_et extensions from Heimdall that were missed the first time
322 Fix bug in badblocks when using O_DIRECT; we need to make sure that
323 we're reading from an offset which is page aligned. For read-only and
324 read-write tests, we try to recover after an error so that we can
325 continue reading on page-aligned boundaries. (Addresses Debian Bug
328 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
331 Updated and clarified various man pages. (Addresses Debian Bug
332 #206845, #222606, #214920, #232406)
334 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
336 Fixed various Debian packaging issues (see debian/changelog).
341 Fixed a build problem so that e2fsprogs would compile with the
342 --enable-profile option to configure selected. (Addresses Sourceforge
345 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
346 Bugzilla Bug #112448)
348 Centralize code which calculates the location of the superblock
349 and block group descriptors so that it is in a single library routine.
351 Added two new functions, ext2fs_file_open2() and
352 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
354 Fix compile_et to output the correct prototype for
355 initialize_xxx_err_table_r() in the header file. (Addresses Debian
358 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
360 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
361 present. This is for when we try stuffing an int into void * pointer.
363 Fix type-punning which can cause gcc 3.x to miscompile code by getting
364 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
365 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
366 **'. The EVMS code uses an ugly union approach since we don't want to
367 modify the EVMS interfaces.
369 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
370 aid build process on systems can use invoke GNU make as "gmake".
372 Added regression testing for mke2fs.
374 Fixed gcc -Wall nitpicks.
376 Fixed various compiler warnings.
378 Add portability fixes for FreeBSD and for using fsctl under Darwin to
379 support ext2 ioctl's.
382 E2fsprogs 1.34 (July 25, 2003)
383 ===============================
385 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
386 a tight loop while waiting for a child fsck to exit in some cases.
387 This burns CPU times which slows down the low-level filesystem check.
389 Added code to mke2fs to assure that the default block size for a
390 filesystem is at least as big as the sector size of the device, if it
393 Changed mke2fs and resize2fs to round the default size of a filesystem
394 to be an even multiple of the VM pagesize in order to avoid a Linux
395 kernel bug introduced when the storage of the buffer cache was moved
398 Mke2fs will warn the user when creating a filesystem with journaling
399 and a blocksize greater than 4096. (Addresses Debian bug #193773)
401 Fixed a bug in resize2fs which caused it to fail on filesystems with a
402 non-empty bad block list. Resize2fs now discards any blocks on the
403 badblock list which are no longer part of the filesystem as the result
404 of a filesystem shrink. (Note: this means that shrinking and then
405 enlarging a filesystem is no longer a reversible operation;
406 information about bad blocks in the part of the filesystem which is to
407 be chopped off will be lost.)
409 Changed resize2fs so the user can use prefixes to specify the units of
410 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
411 and to make the error and informational messages explicitly display
412 the blocksize used by the filesystem, in order to avoid confusion.
413 (Addresses Debian bug: #189814)
415 Added a new debugfs command, dump_unused, which dumps the contents of
416 all unused blocks to stdout. (Useful as an emergency try-to-find
417 deleted data command.)
419 Added a new debugfs command, imap, which prints the location of a
420 specified inode in the inode table.
422 Fixed a bug in the badblocks program which caused it to use one bit of
423 randomness in its non-destructive read/write test, instead of using a
424 full 8 bits of randomness.
426 Added a new option (-t) to badblocks, which allows the user to control
427 the test pattern(s) used when checking a disk.
429 The blkid probe function now more correctly detects UDF filesystems.
431 Fixed a bug in the blkid library which caused it to not update its
432 cache if a filesystem changes from having a label to not having a
435 Fixed a bug in the blkid library wihch could avoid an infinite loop
436 in blkid_find_dev_with_tag() if /proc is not mounted and there the
437 /etc/blkid.tab file has not yet been created.
439 Fixed the badblocks program so that the destructive read/write test
440 honors the -c option, and to use O_DIRECT when possible to avoid
441 thrashing the system block buffer cache.
443 Fixed various NLS issues.
444 - Added Czech and Sweedish translations
445 - Removed testing NYC translation
446 - Fixed NLS support for message abbrevations in e2fsck
447 - Remove de-utf.po, since we shouldn't have two versions using different
449 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
450 simplify the statistics reporting in e2fsck.
452 Changed configure.in so that its defaults for *BSD systems no longer
453 build an fsck wrapper, and not to install in /usr/local by default.
455 Fixed some minor spelling errors/typo's in e2fsck and the configure
458 Fixed various Debian packaging issues (see debian/changelog).
460 Updated and clarified man pages. (Addresses Debian Bug #195616)
465 Fix gcc -Wall nitpicks.
467 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
468 NLS support by default. (Added partial workaround for gettext/Darwin
469 incompatibility problems.)
471 Added full MIT KRB5 and Himdall compaibility support to the com_err
472 library and the compile_et program. (Addresses Debian bug #191900)
474 Added the blkid_known_fstype() function to the blkid library, which
475 returns true if it is passed a filesystem type which is recognized by
476 the blkid probing functions.
478 Improved the documentation for the blkid library.
480 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
481 returns the hardware sector size of a device, if it is available.
483 Added a dependency in the blkid library's .so file to the uuid
484 library, since the former uses the latter. (Addresses Debian bug
487 Added --with-diet-libc and --disable-evms to the configure script.
489 Fixed a minor memory leak in the badblocks program.
491 Fixed a portability problem in tune2fs --- not all systems have strptime().
493 Fixed a portability problem in debugfs with the use of getopt() more
494 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
497 Add support Windows support to ext2fs_get_device_size().
499 Added (normally disabled) debugging code to the Unix I/O manager which
500 causes it to disable all userspace caching if the NO_IO_CACHE is
503 Changed the test I/O manager so it can always be linked into e2fsck,
504 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
505 configure script. The test I/O manager will only print any debugging
506 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
507 variables are set, which specifies which I/O operations are logged and
508 a block number to watch, respectively. The log messages are sent to
509 stderr by default, unless a filename is specified via the
510 TEST_IO_LOGFILE environment variable.
513 E2fsprogs 1.33 (April 21, 2003)
514 ===============================
516 Added a new utility program, logsave, which captures the output of a
517 command in a log file, even if the containing directory hasn't been
518 mounted yet (in which case the it saves the output in memory until it
519 can write out the logfile). This is useful for capturing the
520 output of fsck during the boot sequence.
522 Fixed some portability problems that were causing problems under
523 the Cygwin32 environment.
525 Mke2fs now interprets a negative number to the -b option as a minimum
528 Fixed a bug in mke2fs which was incorrectly checking the argument to
529 the -g option if the default block size was used. (Addresses Debian
532 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
533 it can not find filesystem checkers for jfs, reseirfs, and xfs.
535 E2fsck now updates the global free block and inode counters from the
536 block group specific counters quietly. This is needed for an
537 experimental patch which eliminates locking the entire filesystem when
538 allocating blocks or inodes; if the filesystem is not unmounted
539 cleanly, the global counts may not be accurate.
541 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
542 2.0 is not yet supported; this only pulled in the bug fixes: fixed
543 possible hangs caused by bugs in calling waitpid, and not setting the
544 pipe to non-blocking mode; also fixed a file descriptor leak; made
545 sure all functions call log entry/exit functions.)
547 Badblocks now flushes its output file as bad blocks are discovered.
549 The uuid library is now more paranoid about assuming the correctness
550 of the /dev/random device; it mixes in a stream of bytes from
551 random/srandom, just in case.
553 Update Debian files to reflect the fact that I am now the Debian
554 maintainer of e2fsprogs. Other various Debian-specific packaging
557 Move the source tarball generation functions from the top-level
558 makefile to the util/gen-tarball script.
560 Updated the Turkish .po translation file.
562 Added Heimdal and MIT krb5 extensions to the com_err library to make
563 it more compatible with com_err libraries from those distributions.
565 Changed dumpe2fs to always display the superblock fields relating to
566 the journalling and/or directory indexing feature even if those
567 features are not enabled.
569 Updated and clarify copyright statement vis-a-vis alpha releases of
572 The ss library will now try to dynamically link to the readline
573 library and use it if it is present in the system. This means that
574 the debugfs program now has line editing and history features. The
575 SS_READLINE_PATH environment variable is used to find a readline or
576 readline-compatible library.
578 E2fsck now finds most duplicate filenames (all when rebuilding all
579 directories via the -D option) and offers to delete or rename
580 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
582 Fix bug in e2image. When writing out a raw image file, include data
583 blocks from symlinks that do not store the symlink within the inode.
585 Fix bug in resize2fs which incorrectly moved the block and inode
586 bitmaps for sparse superblock filesystems and incorrectly marked
587 blocks as in use. (Addresses Debian bug #174766)
589 Added a new shared library, the blkid library, which efficiently
590 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
591 and UUID filesystem specifiers without needing to search all of the
592 devices in the system. Instead, the device is looked up in a cache
593 file, and then verified to make sure the blkid cache is correct.
595 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
596 the device name, using the blkid library. (Addresses Debian bugs
599 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
600 used for spaces in device labels.
602 Removed 32-bit limitations for debugfs's dump command.
604 If the user specifies a large number of inodes, Mke2fs will
605 automatically adjust the number of blocks per group to find a valid
606 set of filesystem parameters.
608 Add workaround to detect broken MD devices where when some of the
609 underlying devices are marked read-only, writes to the MD device are
610 silently dropped. E2fsck will detect if there is an attempt to run
611 the journal twice, and abort with an error if this is the case.
612 (Addresses IBM Bugzilla bug #1226)
614 E2fsck will print an error if more than one of the -p/-a, -n or -y
615 options are specified.
617 E2fsck will fix HTREE corruptions in preen mode, without stopping the
618 boot process. This is needed because the 2.4 ext2 filesystem
619 accidentally had the INDEX_FL backwards compatibility code removed.
621 Mke2fs no longer creates filesystems with the dir_index flag set by
622 default; the user has to specifically request it.
624 Update and clarified various man pages. (Addresses Debian bugs
625 #173612, #175233, #175113, and #170497, #185945, #188318)
627 Created man page for the mk_cmds program (from the libss library).
632 Fix various gcc -Wall nits.
634 Fixed a lot of portability problems that caused e2fsprogs not to build
635 successfully under Solaris and Apple/Darwin.
637 Fixed a Makefile dependency to allow building e2fsprogs using parallel
640 Changes to create a subset distribution which consists only of the
641 et, ss, uuid, and blkid libraries. The configure script and top-level
642 makefile were changed to support working with a subset distribution.
644 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
645 actually used, and might people who are looking for
646 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
648 Updated debian files to fix a number of Lintian warnings.
650 Updated config.guess and config.sub with newer versions from the FSF.
652 Removed unnecessary libraries from being linked into the fsck, lsattr,
653 chattr, and blkid executables.
655 E2fsprogs 1.32 (Nomvember 9, 2002)
656 ==================================
658 Fixed a bug in the Unix I/O routines which caused needless writebacks
659 of clean blocks from the unix_io cache (they were erroneously marked
660 as being dirty, so they were getting written back to disk before
661 getting evicted from the disk cache). This was harmless, but it
662 significantly slowed down e2fsck.
664 Made some other minor optimizations to the Unix I/O routines to save a
665 small amount of CPU time.
667 Updated internationalization files.
670 E2fsprogs 1.31 (Nomvember 8, 2002)
671 ==================================
673 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
674 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
675 handling for child process that die unexpectly. Add a hack to force
676 mkfs to create filesystems that won't cause problems with hardware
677 that has 2k or 4k minimum blocksize requirements. Read from child
678 processes in non-blocking mode, so that the GUI continues to update.
680 Fix e2fsck so that it returns the appropriate exit code when the root
681 filesystem has been changed, so that system's rc scripts will be told that
682 the system needs to be rebooted.
684 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
685 was set, some of the descriptor blocks that should have been written
686 out were getting skipped.
688 Changed e2fsck to force out changes to the backup copies of the
689 superblock and block group descriptors when important changes are made
690 to those data structures.
692 Fix a bug where e2fsck could erroneously mark a filesystem as being
693 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
694 introduced in e2fsprogs 1.28.)
696 If journal debuging is enabled using --enable-jbd-debug, the debugging
697 level is now set via the E2FSCK_JBD_DEBUG environment variable.
699 If byteswapping support is disabled using configure --disable-swapfs,
700 skip the tests which depend on byte-swapping, so that "make check"
703 Lshattr will now display the indexed directory flag. Also, some of
704 the more esoteric compression flags are supressed unless compression
705 support has been enabled.
710 E2fsprogs 1.30 (October 31, 2002)
711 =================================
713 When resizing a filesystem, and inodes need to moved, resize2fs will
714 update the inode's ctime field, and the mtime field of the containing
715 directories, so that incremental backups using dump/restore will work
718 In order to avoid spurious errors, e2fsck wil check the last
719 superblock write time to determine whether or not it can safely use
720 the LOW_DTIME checks to determine if there are inodes on the orphan
721 inode linked list that had somehow gotten disconnected. (Addresses
722 Sourceforge bug #620980)
724 Partition in /proc/partitions that being with the string "lvm" are
725 considered real partitions even if they do not end with a number.
727 Fixed a bug in the the uuid generation function, where if /dev/urandom
728 is not present, but /dev/random is, and there isn't sufficient
729 entropy, the get_random_byte function could spin a loop forever.
731 E2fsck, mke2fs, etc. will now reliably notice when image files are
732 mounted using the loopback interface. (Addresses Sourceforge bug
735 When flushing buffers (as is done by badblocks, for example) check to
736 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
737 FDFLUSH ioctl which causes the MD device driver which causes confusing
738 syslog messages about obselete ioctl messages. (Addresses Sourceforge
741 Debugfs's write command now checks to see if the destination filename
742 exists before creating it. (Addresses Sourceforge bug #478195.)
744 When installing man pages, search for compressed man pages using all
745 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
747 Fixed a bug in fsck where multiple filesystems specified on the
748 command were not being checked in parallel due to a logic bug
749 introduced to support the FSCK_MAX_INST environment variable.
751 We have added a new superblock field, s_mkfs_time, which indicates
752 when a filesystem was created. It is set via mke2fs, and printed out
753 by dumpe2fs, but is not actually touched by the kernel.
755 Dumpe2fs has been made more robust by not aborting if there is an
756 error reading the block/inode bitmaps; instead it will still print out
757 the location of the block/inode bitmaps and inode table.
759 Add support for the an alternative block group descriptor layout which
760 allows for on-line resizing without needing to prepare the filesystem
761 in advance. (This is the incomat feature flag meta_bg.)
763 Add support for storing default mount options in the superblock, so
764 that the filesystem can be mounted with specific mount options without
765 needing to specify them on the mount command line or in the /etc/fstab
768 Add support for a new inode flag, which is to be used for indicating
769 the top of directory hierarchies for the Orlov block allocator.
771 Fix e2fsck so that if it creates the lost+found directory, it does so
772 with the more apporpriate permissions of 0700. Also change
773 mklost+found so that it also creates the directory 0700.
775 Fixed format bug in e2fsck if NLS is in use.
777 Add a German translation for e2fsprogs's NLS support.
779 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
780 the beginning of the inode table. This won't matter much, since if
781 there is a bad block at the beginning of the inode table, the root
782 directory won't be available. But at least e2fsck won't crash in this
785 Fixed endian problems in the htree code for e2fsck and debugfs.
787 When byte-swapping a filesystem on a PPC architecture, byte-swap the
788 bitmaps since the historical big-endian ext2 variant had byte-swapped
789 bitmaps, and the ext2fs library assumes this. This fixes the
790 regression test suite on PPC machines.
792 Fix e2image so that it handles a bad block in the inode table
795 E2fsck now uses a more sophisticated algorithm to salvage corrupted
796 directories that recovers more information in the corrupted directory
799 E2fsck now performs additional consistency checks on indexed (HTREE)
802 Fix bug where efsck might get confused about whether a completely
803 empty directory block is an empty leaf block or an interior htree
804 node. This could cause e2fsck to get confused into think that a valid
805 indexed directory was corrupted.
807 E2fsck no longer creates an empty directory entry at the end of a
808 directory block when optimizing a directory. This would cause some
809 earlier versions of the dxdir kernel code to corrupt the directory
810 when attempting to split a node containing an empty directory entry.
812 E2fsck could sometimes in rare circumstances leave the indexed flag
813 set after a small directory was optimized by compressing it instead of
814 indexing it. (This should never happen in real life, since
815 directories that small wouldn't have been indexed, but better safe
818 E2fsck now only updates the master superblock in all cases. This
819 slightly shortens its run time.
821 Ext2ed can deal with directory entries of length 0; previously it
822 would get stuck in an infinite loop.
824 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
825 specifiers. (Sourceforge patch #613447)
827 Badblocks will now work correctly on read-only devices such as
828 CD-ROM's. (Sourceforge patch #600451)
830 Updated and clarified man pages. (Addresses Debian bug #167108)
833 E2fsprogs 1.29 (September 24, 2002)
834 ===================================
836 Fixed a bug in e2fsck which could corrupt a directory when optimizing
837 it (via the -D option) or rebuiliding the hash tree index with a 1 in
838 512 probability, due to a fence post error.
840 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
843 Mke2fs now enables the directory indexing flag by default. (Since
844 this is a compatible feature flag, it's safe to do so.)
846 Tune2fs will support setting the directory indexing feature flag. It
847 will automatically set up the default hash algorithm and hash seed
848 fields in the superblock.
850 If the bone-headed user enters the root filesystem twice in
851 /etc/fstab, the -R option which skips the root filesystem will skip
852 all of them. (Addresses Debian bug #159423). Note! This is not a
853 precedent for dealing intelligently with any other kind of doubled
860 Removed perror declaration in lib/et/internal.h. All modern systems
861 can be expected to define perror() these days. Besides, the lib/et
862 code wasn't using perror at all anyway. :-)
865 E2fsprogs 1.28 (August 31, 2002)
866 ================================
868 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
869 for setting the htree flag is not included yet, although it can be
870 manually turned on via the debugfs program.
872 Clarified e2fsck error message which is printed when it cannot find
873 sufficient contiguous block when relcating filesystem metadata.
875 Added support for building an EVMS plugin module for ext2/3. This
876 module is substantially the same as the EVMS module shipping with EVMS
877 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
878 for use with EVMS 1.0 (which did not include the ext2 plugin module),
879 if the configure --enable-old-evms flag is given.
881 Fsck will search through EVMS volumes when trying to resolve
882 filesystem specifications such as LABEL=xxx or UUID=xxx.
884 Added a new utility program, /sbin/findfs, which will return
885 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
888 Update and clarified various man pages. (addresses Debian Bug #145044,
889 #146437, #131350, #151990, #144621, #141938)
891 If there are no filesystems specified on fsck's command line, fsck now
892 treat that as if the -As options were given. Previously it would
893 simply do nothing. (Addresses Debian Bug #153102)
895 Mke2fs no longer treats a failure to be able to clear the MD signature
896 at the end of the filesystem as a fatal error. (Addresses Debian Bug
899 The e2p library functions (which are used by lsattr and chattr) now
900 double check to make sure the file is a regular file or directory
901 before attempting to use the ext2 ioctls. Some device drivers
902 unfortunately respond to the ext2 ioctl's with unknown behaviour.
903 (Addresses Debian Bug #152029).
905 The extended attribute handling has been updated to correspond with
906 the latest V2 bestbits ACL code.
908 Fixed bug in e2fsck which caused it to not clear the dtime field when
909 processing truncated inodes on the orphan list. This could cause data
910 loss(!) if a filesystem is rebooted before a truncate has been
913 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
914 algorithms. This makes e2fsck much faster in the case of severely
915 corrupted filesystems where a large number of blocks are claimed by a
916 large number of inodes. (Thanks to the 2.5 IDE device driver for
917 inspiring this work.)
919 Resize2fs has been significantly sped up when shrinking and expanding
920 a filesystem by a very small number of blocks (for example, when EVMS
921 is converting a partition to be an EVMS legacy volume).
923 Added a new option to e2fsck, -D, which will optimize or compress all
924 of the directories in the filesystem.
926 E2fsck now catches SIGINT and SIGTERM to make sure it will can
927 properly clean up and only exit at safe points. Fsck will pass
928 SIGINT/SIGTERM to its child processes, and wait until they have all
929 exited before it exits.
931 The uuid parsing code in the uuid library now properly complains when
932 an illegally formated uuid is presented to it. (Addresses Debian bug
935 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
936 and 2.4.17, since the workaround can cause problems when using a 2.4
937 kernel with an old version of glibc built with the 2.2 headers.
939 Fixed a bug in mke2fs where it wasn't properly clearing the initial
940 superblock used by other filesystems. (Addresses Debian bug #147256.)
942 Added support for the synchronous directory feature written by Andrew
945 The debugfs program can delete directories using the rmdir command.
947 Add support for 8k and 16k filesystems (for systems with page sizes
948 that are greater or equal to 8k or 16k, respectively). Note that
949 these filesystems can not be mounted on x86 systems, or other systems
950 with only 4k page sizes, due to limitations in the current Linux VM
953 Resize2fs requires that the filesystem state be valid and have no
954 errors; otherwise, e2fsck -f must be run first. (Previously it simply
955 required that the last fsck time be greater than the last mount time.)
957 Configure now defaults the man pages directory to /usr/share/man on
960 E2fsck now offers to truncate inodes which contain too many blocks (so
961 that i_blocks would overflow. Also fixed handling of large sparse
964 E2fsck now more completely checks for symlink validity, including
965 requiring NULL termination and length checks.
967 E2fsck will offer to try forcing a disk write to remap a bad block
968 after finding a read error when reading a filesystem metadata block.
970 Fixed a bug in debugfs which caused the -b and -s options to crash
971 debugfs, as well as breaking the testb, setb, and clearb functions.
973 Added a bmap command to debugfs which calculates the logical to
974 physical block mapping for a particular inode.
976 Fixed a bug in code which checked to see if a device was mounted which
977 sometimes (rarely) failed in the case of a plain file.
979 Fixed a bug in resize2fs where when it reported an error, it would
980 print a message erroneously indicating that the filesystem had been
981 resized before it aborted.
983 When resizing a plain file which is smaller than the requested size,
984 resize2fs will attempt to extended the file so that programs like
985 e2fsck will not complain that the file is too small.
987 Resize2fs will print the actual new size of the filesystem when it is
990 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
991 information on big-endian systems.
997 Fixed collisions with C++ reserved words.
999 Added portability fixes for building e2fsprogs on the HURD and AIX.
1001 Added the ext2ed program for creation of test cases. (ext2ed has many
1002 limitations and bugs which make it unsuitable for production use.)
1004 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
1005 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
1006 name_len field is byte swampped on big-endian machines, since in the
1007 V2 structure, name_len is a char field which is doesn't need to be
1008 byte swapped --- except if an old-style kernel had byte-swapped the
1009 name_len field as part of the V1 structure.
1012 E2fsprogs 1.27 (March 8, 2002)
1013 ==============================
1015 The warning messages for mke2fs now go to standard error.
1017 Fixed to make sure "make check" runs all of the test programs with
1018 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
1020 The mke2fs program checks the boot sector for the BSD disk label, and
1021 avoids erasing it if it is there.
1023 Fixed a bug in e2fsck which caused it to core dump if the journal
1024 inode was missing when it was supposed to be there.
1026 E2fsck now prints ranges in pass 5 when printing deltas for the block
1029 Debugfs's "ls -l" command now will print out the file type information
1030 in the directory entry.
1032 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
1033 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
1035 Debugfs can now examine the experimental directory indexing
1038 Fixed bug in debugfs which caused it to core dump if modify_inode is
1039 called without an open filesystem.
1041 The debugfs lsdel command now runs its output through a pager first.
1043 When installing manual pages, remove the compressed manual pages first.
1045 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
1047 Fix the 2.4 resource limitation workaround introduced in 1.26 which
1048 actually broke things on mips32, sparc32, and Alpha platforms.
1050 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
1051 (which is required by the newer libintl libraries).
1056 Fixed various gcc -Wall complaints.
1058 Fixed a few memory leaks in the e2fsck journaling code, and in the
1059 ismounted code checking for a swap device.
1061 Add new inode I/O abstraction interface which exports an inode as
1064 Exported ext2_file_flush as a public interface.
1066 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
1068 Lots of small random portability fixes to make e2fsprogs build under
1069 AIX --- even without the 5L compatibility toolkit, and even using the
1070 uber-crippled AIX native C compiler.
1073 E2fsprogs 1.26 (February 3, 2002)
1074 =================================
1076 Dumpe2fs will keep going now if the bad block inode can't be read.
1077 (Previously it stopped with a fatal error.)
1079 E2fsck will now give an opportunity to run the journal even if the
1080 recovery flag is not set. This is the default behaviour if e2fsck is
1081 using a backup superblock, since the needs_recovery flag will never be
1082 set in the backup superblock copies.
1084 E2fsck now automatically finds the backup superblock/group descriptors
1085 even when the primary superblock is completely destroyed for 2k and 4k
1086 filesystems. (Previously it just guessed/assumed that we were dealing
1087 with a 1k filesystem in that case, and users had to manually specify
1088 the backup superblock number.)
1090 Fixed a bug in e2fsck where it dereferences a null pointer when there
1091 is a problem opening a filesystem in preen mode.
1093 E2fsck now handles external journals correctly; previously it trashed
1094 the external journal device if the journal needed to be replayed.
1096 Work around ulimit incompatibility problem caused by recent 2.4
1097 kernels; the unix IO module will automatically try to set any resource
1098 limits to be infinite on startup.
1100 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1101 bitmap if it wasn't present and the blocksize was 2k or 4k.
1102 (Addresses Debian Bug #116975)
1104 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1105 clearing the new V2 fields if they do not make sense or if the ext3
1106 superblock is version 1 superblock.
1108 E2fsck will automatically relocate the ext3 journal from a visible
1109 file (i.e., /.journal) to an hidden inode if the filesystem has been
1110 opened read/write. This allows the users to add a journal while the
1111 filesystem is mounted, but the next time the system is rebooted, the
1112 journal file will disappear. This avoids problems with backups,
1113 stupid operators with superuser bits, etc.
1115 Fix a bug in fsck where it would not support a filesystem type of
1116 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1118 Fsck now supports fstab entries of the form "ext3,ext2". It will also
1119 automatically identify reiserfs filesystems.
1121 The number of processes spawned by fsck can now be limited using the
1122 FSCK_MAX_INST environment variable.
1124 Fsck now searchs the LVM proc hierarchy to find logical volumes which
1125 should be searched for UUID and label information.
1127 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1128 limit if at all possible, when opening a block device. (The filesize
1129 limit shouldn't be applied against writes to a block device.)
1131 In mke2fs and e2fsck, specifying the -c option twice will now do
1132 a read/write test on the disk. Update the man pages to encourage
1133 using the -c option, and to discouraging running badblocks separately,
1134 since users tend to forget to set the blocksize when running
1137 Mke2fs now automatically clears the immutable attribute on a
1138 pre-existing .journal file left over from a previous failed attempt to
1139 add a journal to an alreadyy-mounted filesystem.
1141 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1144 Mke2fs now creates the lost+found directory with permissions of 0700,
1145 so that files that had previously lived in protected directory are
1146 safe if they get dropped in lost+found and the system administrator
1147 doesn't deal with immediately. (Addresses Debian #bug 118443)
1149 Mke2fs and e2fsck (and all programs that use the
1150 ext2fs_check_if_mounted function) will now properly identify that a
1151 device is mounted, even in cases where devfs has confused things with
1152 multiple devices names with the same identity, or if a dim-witted
1153 system administrator has done something stupid like creating device
1154 file aliases in their home directory. Also now checks for swap devices
1155 by using /proc/swaps. (Addresses Debian bug #106622)
1157 Added a new option (-T) to tune2fs which sets the time a filesystem
1160 Speed up e2image when creating sparse raw image files by optimizing
1161 away excess lseek() system calls.
1163 Fix support of large (> 2GB) files when used as a filesystem in
1164 mke2fs, tune2fs, debugfs, and findsuper.
1166 Debugfs's stat and icheck commands now properly deals with large (>
1169 Debugfs's set_super_value command now prints out the list of valid
1170 superblock fields which can be set using the command.
1172 Debugfs's rm and kill_file command now updates the superblock free block
1173 and inode counts, thus keeping the filesystem consistent.
1175 Debugfs's lsdel command now takes an optional argument which allows
1176 the user to only see the most recently deleted files.
1178 A new command (undel) was added to debugfs which automates
1179 undeleting a deleted inode and linking it back to a directory.
1181 Debugfs's ls command now takes a new option, -d, which lists
1182 deleted directory entries.
1184 Debugfs's testb, freeb, setb, and find_free_block commands now take an
1185 optional count argument.
1187 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1188 be used to signal that a particular inode should not be eligible for
1189 tail-merging --- this is needed for programs like LILO.
1191 The findsuper (an unreleased, uninstalled utility program) has been
1192 improved to add extra validity checks and to add a progress meter.
1193 (It is still an unsupported program; the officially supported way to
1194 recover from a trashed partition table is to use gpart; findsuper is
1195 for wizards only. :-)
1197 Debugfs was fixed to compile with "configure --disable-swapfs".
1199 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
1201 Added new translation file for Turkish.
1206 Fix general gcc -Wall complaints.
1208 E2fsprogs (mostly) works with the dietlibc.
1210 The programming texinfo file has been expanded to include description
1211 of additional libext2fs functions. (Still not compeltely done, but a
1212 lot of the more important functions have been documented.)
1214 Added a umask structure to struct_ext2_filsys, which currently only
1215 modifies the behaviour of ext2fs_mkdir(), but if we add any file
1216 creation functions to libext2fs, we should also make sure they respect
1219 The build-rpm script was fixed to be a bit more safe.
1221 The tests' Makefile now has a way of automating test case creation
1222 for e2fsck, using "make testnew".
1224 Created a new function, ext2fs_dir_iterate2 which passes more
1225 information to the callback function (identical to the one used by
1226 ext2fs_dblist_dir_iterate). The directory iterator functions take a
1227 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1228 directory entries. If the directory entry is deleted, the callback
1229 function will be called with the entry paraemter set to
1230 DIRENT_DELETED_FILE.
1232 Added new functions, ext2fs_inode_alloc_stats and
1233 ext2fs_block_alloc_stats, which takes updates block/inode allocation
1234 statistics in the bitmaps, block group descriptors, and superblock
1235 when inodes or blocks are allocated or deallocated.
1238 E2fsprogs 1.25 (September 20, 2001)
1239 ===================================
1241 This is primarily a bug-fix release; no new features were added, but
1242 there are a number of embarassing bug fixes and cleanups applied.
1244 Fix a bug mke2fs which causes stack garbage to be written to disk when
1245 zapping disk sectors. (This bug could cause mke2fs to core dump for
1246 some kernels, I suspect with security enhancement patches.)
1248 Remove unneeded #include of <linux/config.h> which was breaking
1249 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1251 Updated tune2fs man page to reflect the fact that adding or removing a
1252 journal doesn't require running e2fsck.
1254 Remove use of AC_REQUIRE from autoconf which had been used to prevent
1255 AC_CANONICAL_HOST from being called twice; unfortunately this causes
1256 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1257 used outside of autoconf macros. Fortunately, it doesn't seem to be
1258 necessary any more, anyway.
1260 E2fsck will now not fall back to an alternate superblock if the user
1261 specifies the superblock location explicitly on the command-line.
1262 This allows easier recovery from a situation where the primary
1263 superblock and block groups are slightly corrupted, but the backup
1264 superblocks are completely broken.
1266 Fix problem which caused compile_et and mk_cmds to blow up if
1267 e2fsprogs was in a directory with a pathname that contained spaces.
1269 We are now more paranoid about checking the entry in /etc/mtab to make
1270 sure the filesystem is really mounted, since some broken distributions
1271 (read: Slackware) don't initialize /etc/mtab before checking non-root
1272 filesystems. (Slackware also doesn't check the root filesystem
1273 separately, and reboot if the root filesystem had changes applied to
1274 it, which is dangerous and broken, but there's nothing I can do about
1277 Make UUID library C++ friendly by adding appropriate extern "C"
1278 declarations and using const in the function declarations.
1280 Fix up the com_err texinfo file so that it can product a valid info
1281 file (previously, it could only be used to generate paper
1282 documentation using texinfo.tex).
1285 E2fsprogs 1.24a (September 2, 2001)
1286 ===================================
1288 Fix brown-paper bug in mke2fs which caused it to segfault when
1289 printing the version string.
1292 E2fsprogs 1.24 (August 30, 2001)
1293 ================================
1295 Revert the BLKGETSIZE64 support, since for some distributions, this
1296 ioctl has been used by an unofficial kernel patch to update the last
1297 sector on the disk, and this was causing disk corruption problems as a
1300 Mke2fs is now more careful about zapping swap space signatures and
1301 other filesystem/raid superblock magic values so that programs like
1302 mount who try to use hueristics to determine the filesystem type of a
1303 partition are less likely to be confused.
1305 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1306 regular file (since Andreas Dilger's on-line resizing tools will set
1309 Fixed some minor texinfo, man pages nits for spelling errors,
1310 texinfo warnings, etc. (Addresses Debian bug #110621.)
1312 E2fsprogs program no longer print the filesystem version number
1313 (i.e. 0.5b), since it only confuses people and doesn't serve any real
1316 E2fsck will once again compile under libc5, since it will supply its
1317 own version of strnlen if necesssary.
1319 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1320 when specifying the external journal device. tune2fs will also search
1321 devices looking for the externla journal debice when removing.
1323 E2fsprogs 1.23 (August 15, 2001)
1324 ================================
1326 Add initial support for extended attributes (EA); e2fsck will
1327 correctly handle a filesystem with EA's and check the EA blocks for
1330 E2fsck's symlink sanity checking has been cleaned up. It now checks
1331 the i_size value of fast symlinks, and checks for immutable flags
1332 being set of symlinks, etc.
1334 E2fsck now offers to clear inodes which are special files that have a
1335 non-zero i_blocks or i_size field. (The i_size field check was in the
1336 previous version of the code, but due to a bug it didn't offer to
1337 clear the inode unless i_size and i_size_high were both non-zero.)
1339 E2image can now create "raw" image files, which only contain the
1340 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1341 debugfs, etc., can be run directly on the raw image file.
1343 Add support for the 64-bit block device patches.
1345 Fixed bugs in creating external journals with a 1k blocksize.
1347 Add initial support for external journals (so long as the external
1348 journal only supports a single filesystem) in e2fsck.
1350 Remove requirement for needing to run fsck on a filesystem after
1351 removing a journal (either internal or external).
1353 The man pages now document how to create and manage external journals.
1355 Speed up the check of an ext3 filesystems by avoiding a needless flush
1356 of all of the superblock and block group descriptors.
1358 Speed up creating an internal journal using tune2fs in the case where
1359 the filesystem has a lot blocks already allocated.
1361 Tune2fs has been fixed to make sure that only error messages go to
1362 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1364 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
1365 now not set the sparse_super feature. (Addresses Debian bug #108165)
1367 Add support in fsck for the filesystem type "auto".
1369 Fsck -A will not try to interpret device names for filesystems which
1370 have a pass number is 0. (Addresses Debian bug #106696).
1372 Fsck prints a warning message if now valid filesystems are passed to
1373 it. (Addresses Debian Bug #107458.)
1375 E2fsck now gives an explicit warning if there filesystem still has
1376 errors at the end of the run. (Addresses Debian bug #104502)
1378 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
1379 reflects an error. E2fsck will also not run the orphan list if the
1380 filesystem contains errors, since the orphan list might be corrupted.
1382 E2fsck now prints the number of large files when given the -v option.
1384 Fixed minor memory leaks in e2fsck.
1386 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
1389 E2fsprogs 1.22 (June 22, 2001)
1390 ==============================
1392 Fixed a bug in e2fsck's handling of orphan inodes which are special
1393 files (i.e., block/character device files, named FIFO's, etc.).
1395 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1396 tune2fs to fail at adding a journal to a mounted filesystem.
1398 Fixed a few big-endian bugs in e2fsprogs
1399 * The directory block functions were accidentally reporting
1400 some directories as corrupted when they weren't.
1401 * If e2fsprogs is compiled --disable-swapfs, the C language
1402 equivalents weren't being included for big-endian platforms.
1403 (Fixes Debian bug #101686).
1405 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1410 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1411 ioctls, and allow them to be defined for non-i386 platforms.
1413 The uuid.h header file is now protected against multiple inclusions.
1415 E2fsprogs is now being developed using BitKeeper. Changed the test
1416 scripts to deal with BK's stripping CR characgters from text files,
1417 and changed the top-level Makefile.in to avoid including BitKeeper
1418 files when generating the source tarball.
1421 E2fsprogs 1.21 (June 15, 2001)
1422 ==============================
1424 Added new configure flags which allow a subset e2fsprogs to be built;
1425 this is most useful for boot floopies, since the resulting shared
1426 libraries and programs are slimmed down by removing features that
1427 aren't necessary for a boot floppy. The new flags that were added
1428 are: --disable-swapfs, which removes support for byte swapping old
1429 legacy PPC/68k filesystems, --disable-debugfs, which removes support
1430 for debugfs from the libext2fs library, --disable-imager, which
1431 removes support for the e2image program, and --disable-resizer, which
1432 removes support for resize2fs.
1434 E2fsck now prints the number of mounts or days elapsed since the last
1435 check when e2fsck is forced to check an otherwise clean filesystem.
1437 Tune2fs now prints an informative message about how often a filesystem
1438 will be checked when adding a journal to the filesystem, to remind the
1439 user that he/she may want to adjust those parameters using tune2fs
1442 Worked around hurd brain-damage which causes e2fsck to sometimes
1443 believe a filesystem is the root filesystem based on device numbers
1444 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1447 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1448 erroneous error with the -F option was specified.
1450 Fixed a ext3 recovery bug in the revoke handling; synchronized with
1453 Fixed two bugs in e2fsck's handling of dup block handling, dealing
1454 with relatively uncommon edge cases: a directory with an indirect
1455 block which is claimed by another file, and when the last inode in the
1456 filesystem has blocks claimed by another file.
1458 E2fsck now checks to see if the i_size field of a fast symlink is too
1459 big, and offers to clear the symlink if so.
1461 E2fsck now checks to see if i_size_high of special files is non-zero,
1462 and offers to clear i_size_high.
1464 Fix e2fsck's handling of incompatible journal flags so that the user
1465 has chance to abort, and then has the option to clear out the journal
1466 entirely. (Addresses Debian bug #98527.)
1468 Fixed a bug in fsck which could cause it to core dump if a mix of
1469 standard and non-standard device names are used in /etc/fstab.
1470 (Debian bug #100559)
1472 Fixed a bug in debugfs which caused read errors when copying a file to
1475 The debugfs set_super_value command can now modify the s_lastcheck field.
1477 Fixed a bug in lsattr and chattr which was accidentally introduced in
1478 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
1479 directories correctly because the change modified the layout of struct
1480 dirent to be incompatible with the libe2p shared library.
1482 Cleaned up the mke2fs manual page and included a discussion about why
1483 it's good to periodically check the filesystem even when journaling is
1489 Fix general gcc -Wall complaints.
1491 The types needed by the ext2 header files are now provided by
1492 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1494 Integers are now preferred to longs when trying to find a 32-bit type
1495 in ext2_types.h. Also, if linux/types.h has already been defined,
1496 don't try to redefine the types.
1498 Fixed make depend script so that it automatically corrects the
1499 pathname cleanups performed by make -M, so I don't have to fix them up
1502 Fixed the d_loaddump test case to be more robust, and not depend on
1505 Removed debugfs's dependence on pread(), which was accidentally
1506 intrudced in e2fsprogs 1.20
1508 Fixed a performance bug in the libext2fs's icount routine; the size
1509 estimate of the icount array was incorrectly being calculated.
1511 Removed use of the badblocks compatibility functions in the e2fsprogs
1514 Added paranoia code which protects against strange cases where /etc
1515 isn't on the root filesystem, or if /etc/mtab doesn't exist.
1517 The header file ext2_types.h is now installed.
1519 Autoconf is used to determine when we are on big-endian machines,
1520 instead of doing run-time tests, to save a few bytes of code.
1522 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1523 functions are no longer inline functions, which saves space and
1524 doesn't really cost any real performance.
1526 The ext2fs library no longer depends on the e2p library. (What need
1527 there was of it --- namely, fsetflags, was coded in-line).
1529 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
1530 when the user is stupid and tries compiling the package using "make
1533 Miscellaneous code cleanups:
1534 * Added missing files from Makefile.in's SRCS file, so that
1535 their dependencies would be properly calculated.
1536 * Removed redundant code
1537 * Fixed comments in code
1538 * Removed no-longer unneeded argsused #pragma.
1541 E2fsprogs 1.20 (May 20, 2001)
1542 =============================
1544 Add support for replaying the ext3 journal purely in user mode,
1545 including handling the orphaned inode list. Used code contributed by
1546 Andreas Dilger, with bug fixes and the orphaned inode handling done
1549 The mke2fs and tune2fs programs can create or modify a filesystem to
1550 include an ext3 journal. Tune2fs also can be used to remove an ext3
1551 journal from a filesystem.
1553 E2fsck will now check for the existence of a linked list of orphan
1554 inodes in the superblock, and clear those inodes before starting the
1555 rest of the filesystem check (but after the journal playback).
1557 E2fsck now validates the file descriptor passed to the -C option,
1558 which saves against the completion bar getting written to an
1559 unexpected location, such as the disk being checked. (Debian
1560 bug/wishlist #55220)
1562 E2fsck will now bump the filesystem revision number from zero to one
1563 if any of the compatibility bits are set.
1565 Fixed a bug where a badly corrupted directory on a big endian system
1566 could cause e2fsck to die with a bus error. The
1567 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
1568 the ext2 library now does alignment sanity checks on the rec_len field
1569 of the directory entry before using it.
1571 The ext2 library has been enhanced to make tune2fs safe to run on
1572 mounted filesystems. (Users could usually get away with using tune2fs
1573 on mounted filesystems before, but with the advent of ext3 and
1574 journaling, it became important to make tune2fs was *really* safe for
1575 use even when the filesystem being modified is mounted.) E2label is
1576 now implemented by tune2fs using an argv[0] dispatch, so that e2label
1577 is also now safe for use on mounted filesystems.
1579 Added a new program, e2image, which creates a backup of critical ext2
1580 filesystem data structures. The generated image file can be examined
1581 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
1582 the image file to help recover very badly damaged filesystems.
1584 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
1585 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
1586 large file when deciding whether or not the filesystem has large files.
1588 Fixed lsattr and chattr so that they work correctly on large files.
1589 (Fixes Debian bug #72690.)
1591 Removed limitation in get_device_size() which imposed a one terrabyte
1592 filesystem limitation. (Most 2.2 kernels still have a signed int
1593 problem which cause 1 TB block device limitation. Fortunately, the
1594 kernel patches to fix this are much easier than fixing the 2TB
1595 limitation in the kernel. :-)
1597 A max_mount_count of zero is now treated as if no mount count were
1598 set. (Previously, no mount count was indicated by using -1, and a
1599 mount count of zero caused e2fsck to always be run.)
1601 Mke2fs supports two new filesystem types largefile and largefile4.
1603 Mke2fs now adds some randomness in s_max_mount_count so that multiple
1604 filesystems won't be all checked at the same time under normal
1607 Fixed bug in the progress bar printing code which could cause e2fsck
1608 to core dump on an illegal filesystem.
1610 Fixed bug in fsck which could allow more than one instance of e2fsck
1611 to be printing a progress bar. (Debian bug #65267)
1613 Fsck using a UUID or a LABEL specifier will work even if devfs is
1614 compiled into the kernel and not mounted. If the pathnames in
1615 /proc/partitions are incorrect, fsck will search /dev for the correct
1616 device (using the new ext2fs_find_block_device library function).
1617 Fsck now also checks the RAID devices first so that they are properly
1618 found when they are in use. Support has also been added to support
1619 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
1621 Fixed a bug in fsck which caused it not deal properly with 16
1622 byte long filesystem labels.
1624 Fsck's -t option has been made a lot more flexible. The semantics for
1625 what happens if a comma-separated list to fsck has been regularized,
1626 and it is now possible to filter what filesystems will get checked
1627 based what is in the filesystem's fstab entry's option field. (Debian
1630 The dumpe2fs program can now print out the group description
1631 information in hex, and also prints the location of the superblock and
1632 block group descriptor for those block groups that have them.
1634 Mke2fs now clears the ext2 superblock before it starts creating a
1635 filesystem, so that the superblock magic number is only written if the
1636 filesystem creation process successfully completes.
1638 The debugfs program's stat command now pretty-prints the blocks used
1639 by an inode so that it's more compact and informative.
1641 The debugfs stats command now uses the same libe2p code (which is used
1642 by dumpe2fs) to print the superblock header information. This is more
1643 complete, and it avoids a bit of code duplication.
1645 Added a new debugfs command, set_super_value (ssv) which allows the
1646 user to set arbitrary superblock fields.
1648 Debugfs was extended to support inode numbers in hex (by prefixing
1649 them with 0x), and so that modify_inode can set the inode generation
1650 number. Also, there is now a new function command called logdump
1651 which will dump an ext3 journal.
1653 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
1656 Debugfs's dump command now stops immediately upon reporting a disk
1657 read error. (Fixed a bug in ext2fs_file_read library routine which
1658 caused debugfs not to stop.) (Debian bug #79163)
1660 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
1661 checked before /etc/mtab is used, since /proc/mounts is more likely to
1664 Added portability fixes for Solaris and Linux/ia64.
1666 Various manual pages were clarified and cleaned up. (Fixed debian
1667 bugs #63442, #67446, and #87216)
1673 The e2fsck message printer now supports %Iu and %Ig, which will print
1674 out the inode's user and group owners, respectively.
1676 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
1677 that no longer dependent on the system having the correct version of
1678 the kernel header files.
1680 Added a new function to libext2, ext2fs_find_block_device(), which
1681 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
1682 device given its device number.
1684 Added a new function to libext2, ext2fs_sync_device, which centralizes
1685 all of the places which might try to use the BLKFLSBUF or FDFLUSH
1686 ioctls (and usually failing to define them since the system header
1687 files don't usually do this for us, and we're trying to avoid usage of
1688 kernel include files now).
1690 Added new utility programs in tests/progs: random_exercise and
1691 hold_inode. They aren't built by default; they're useful for
1692 exercising ext3 filesystem code.
1694 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
1695 the filesystem close functions to only update the superblock, and to
1696 not touch the block group descriptors. Needed by tune2fs when
1697 modifying a mounted filesystem.
1699 Got rid of struct ext2fs_sb and replaced it with the standard struct
1700 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
1701 source (but not binary) compatibility of some users of the ext2
1702 library. Those applications should just simply do a global search and
1703 replace of struct ext2fs_sb with struct ext2_super_block, and include
1704 the new header file <ext2fs/ext2_fs.h> which defines it.
1706 The ino_t type has been renamed ext2_ino_t to protect applications
1707 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
1708 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
1709 unexpected ABI change.
1711 The Makefiles have been reworked so that "make check" can be run from
1712 the top-level Makefile.
1714 Fix general gcc -Wall complaints and removed dead code.
1716 Remove use of NOARGS, because we assume everyone does ANSI C these
1719 Added build-rpm script from sct.
1721 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
1724 New function ext2fs_flush_icache which must be called if the
1725 application program modifies the inode table blocks without going
1726 through ext2fs_write_inode() interface.
1728 New ext2fs_check_mount_point() function, which will return the mount
1729 point of a device if mounted.
1731 The io_channel abstraction now has an optional interface,
1732 io_channel_write_range, which allows specific byte ranges to be
1735 The unix_io IO channel now supports write-through caching, so that
1736 journal creation is more efficient.
1738 Added x86 assembly language routines to support byte swapping, to
1739 reduce executable size.
1741 Fixed bug in the utility program subst so that it's possible to
1742 replace a substitution variable with a zero-length string.
1744 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
1745 slipped into some of the problem number.
1747 E2fsprogs 1.19 (July 13, 2000)
1748 ==============================
1750 Release the resize2fs program since the timeout before it could
1751 be released under the GPL has finally expired.
1753 Add experimental support needed for the ext2 compression patches.
1754 This requires compiling e2fsprogs with the --enable-compression flag
1755 to the configure script.
1757 Added ext3 journalling support. E2fsck will run the journal (if
1758 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
1759 installed as a symlink to e2fsck. Fsck has been taught about ext3,
1760 and treats it the same as ext2 in terms of the progress bar logic.
1761 Dumpe2fs will display the superblock journaling information if the
1762 filesystem has a journal. The ext2 library will now permit opening an
1763 ext3 filesystem with the recovery flag set. This is necessary for
1764 on-line dump's to work correctly, but there may be issues with this
1765 working well since ext3 is much less agressive about syncing blocks to
1766 the filesystem, since they're safe on the journal.
1768 Tune2fs and e2fsck have been changed to allow the mount_count check to
1769 be disabled by setting max_mount_count to -1. (This was already
1770 supported by the kernel.)
1772 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
1773 are used for ext3 as well.
1775 Added internationalization support for e2fsprogs; must be enabled
1776 by passing --enable-nls to configure.
1778 Always use the provided ext2fs header files to insulate ourselves from
1779 kernel version changes. Which include files are used by e2fsprogs
1780 have also been cleaned up to improve portability.
1782 Limit the number of times that e2fsck updates the progress bar so that
1783 people who are booting using a 9600 baud console don't get swampped by
1786 Improved the loop detection algorithm in e2sck's pass #3 so that it is
1787 much, much faster for large filesystems with a large number of
1790 The memory footprint for e2fsck is now slightly smaller than before.
1792 E2fsck now checks if special devices have a non-zero size, and offers
1793 to clear the size field if it finds such an inode.
1795 E2fsck now checks if special devices have the append-only flag set,
1796 and offers to clear the inode.
1798 E2fsck now properly handles some "should never fail" cases during a
1799 bitmap copy in pass5.
1801 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
1803 E2fsck now calculates the correct location of the backup superblock in
1804 the case of filesystem blocksizes > 1k.
1806 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
1807 which normally didn't cause problems under most filesystem parameters,
1808 but could cause a valid superblock to be rejected in extreme cases.
1809 Other checks for validating superblock values were made more
1812 Added non-destructive write testing to the badblocks program, courtesy
1813 of David Beattie. The badblocks also now has an option to input the
1814 current set of bad blocks, so that known bad blocks are skipped to
1815 speed up the badblocks test. There is also a persistent rescan
1816 feature which causes badblocks to run until it has completed some
1817 number of passes without discovering any new bad blocks.
1819 Badblocks now checks to see if the device is mounted and refuses to do
1820 the tests involving writing to the device if it is mounted. Also,
1821 badblocks now allows the number of blocks to be checked to be
1822 defaulted to the size of the partition.
1824 Fixed a bug in fsck which didn't allow non-root users to be able to
1825 check filesystems if there were any LABEL= or UUID= entries in
1828 The Hurd doesn't support the filetype filesystem feature. The mke2fs
1829 program now makes sure that for the Hurd, the filestype feature is
1830 turned off. E2fsck will check to see if the filetype feature is
1831 turned on for Hurd filesystems, and offer to turn off the feature.
1833 Mke2fs now has a safety check to make sure the number of blocks do not
1834 exceed 32 bits even on a 64 bit platform.
1836 Really fixed a bug in fsck to allow "fsck -As" to run interactive
1837 fsck's. (For those people who like to do interactive fsck's in the
1840 Debugfs has a few new features: the rdump command, which will do a
1841 recursive dump of a directory and all of its contents, and the lcd
1842 command which does a local chdir (much like the ftp command of the
1843 same name). In addition, the debugfs program and the open_filesystem
1844 command now takes three new options: -b and -s, which allows the
1845 blocksize and superblock location to be specified, and the -c option
1846 which is used in catastrophic situations where the block group
1847 descriptors are corrupt. If the -c option is specified, debugfs will
1848 skip trying to read in the block and inode bitmaps.
1850 Debufs's lsdel command was fixed to handle bad blocks in the inode
1853 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
1856 General improvements in error messages
1858 - Mke2fs prints a sane error message if the partition size is zero
1859 (usually because the partition table wasn't reread by the
1860 kernel due to the partition being busy), instead of "invalid
1861 argument passed to ext2 library while initializing superblock".
1863 - Fsck now prints more self-explanatory message if an invalid UUID=
1864 or LABEL= specification is passed to it.
1866 UUID library changed to use the LGPL.
1868 Fixed a bug in the UUID library where very rapid calls to the
1869 time-based UUID generator could cause duplicate UUID's to be returned.
1870 This was not a problem for e2fsprogs, but it could be a problem for
1871 other users of the library.
1873 Make the UUID library more robust in the face of missing or an
1874 improper /dev/urandom or /dev/random files.
1876 Added some random portability fixes for Solaris.
1878 Some minor man page updates.
1880 Fixed a memory leak in the ss library.
1886 We now try to use lseek64 and open64 from the LFS if possible.
1888 The 3rd parameter in e2p's print_flags is now a flags word, instead of
1891 The mark and unmark bitmap functions now return the previous state of
1892 the bit that was being changed, which is useful for some speed
1895 The following functions have been added to enhance the badblocks list
1896 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1897 ext2fs_badblocks_equal.
1899 The ext2 header files now have the latest journalling fields to the
1902 The ext2fs_mkdir function in libext2fs now properly backs out of error
1903 conditions robustly.
1905 Cleaned up makefiles:
1906 - to cleanly compile with the -j flag.
1907 - so distclean removes all generated files.
1908 - so in case of an error while installing header files, the make aborts.
1910 Fix test_script so that it works correctly when compiling in the
1913 The random UUID generation routine has been made slightly better in
1914 the case where /dev/random doesn't exist. (Use of randomly-based UUID
1915 is still not recommended if /dev/random doesn't exist, however; it's
1916 better to use the time/ethernet MAC address UUID in this case.)
1918 Clean up the build process so it's more friendly in case of missing
1921 The ext2fs header file can now be #include'd into C++ programs.
1923 The e2p.h header file is now installed.
1925 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
1929 E2fsprogs 1.18 (November 10, 1999)
1930 ==================================
1932 Fix a core dumping bug in e2fsck if an imagic inode is present or
1933 (more rarely) if the filesystem is badly corrupted enough that e2fsck
1934 has to restart pass 1 processing. E2fsck now closes the filesystem
1935 before freeing a large number of its data structures, so in the case
1936 of future memory faults, at least the fixed filesystem will be fully
1939 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1940 imagic inode, it will offer to clear the imagic flag.
1942 E2fsck will now offer to clear the immutable flag on special files
1943 (device/socket/fifos) when running it in non-preen mode.
1945 E2fsck will now set the filetype when creating /lost+found, and when
1946 connected orphaned inodes to /lost+found.
1948 Debugfs's ncheck and icheck commands now handles the case where there
1949 are bad blocks in the inode table without bombing out.
1951 The badblocks list processing code has been made more efficiently for
1952 appending a large number of (ordered) badblocks to the badblocks list.
1954 Some minor man page updates.
1956 Fsck now allows interactive e2fsck's when using fsck -As (not a common
1957 mode, but some people like to do this in boot scripts for silly reasons).
1962 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1963 with the problem code convention.
1965 The badblocks list regression test program has been updated to work
1966 with previously made API name changes.
1968 The ext2fs_free() command now uses the new badblocks API to avoid
1969 using the compatibility layer.
1971 Added new regression test cases; the run_e2fsck test script now
1972 supports the ability for a test case to run a prepratory command
1973 before running e2fsck.
1975 E2fsprogs 1.17 (October 26, 1999)
1976 =================================
1978 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1981 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1982 thus potentially causing problems if a binary UUID contained a NULL
1985 E2fsck now uses stricter checks for directory entries in pass 2:
1986 zero-length filenames are not allowed; neither are 8 byte long
1989 The debugfs "dirty" command now clears the filesystem valid bit.
1990 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
1991 bit in the in-core superblock image. The new functionality is more
1992 what the user expects, and is more useful.)
1994 Added a debugging hook to test parallel fsck; if the environment
1995 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1996 will be checked in parallel when they normally would not be.
2001 Fixed some #ifdef's for compilation under the Hurd OS.
2003 Fixed minor W2K compatibility problems.
2005 Fixed some miscellaneous GCC warnings.
2008 E2fsprogs 1.16 (October 22, 1999)
2009 =================================
2011 Fixed a race condition bug in fsck; when printing a progress bar, if
2012 checking multiple filesystems in parallel, it was possible for fsck to
2013 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
2014 handler, which would cause it to terminate with a signal 10.
2016 E2fsck now properly handles filesystems that have the
2017 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
2018 filesystem into using or not using FILETYPE feature.
2020 E2fsck now properly handles filesystems that have the IMAGIC feature
2021 turned on (this is used on Linux AFS servers).
2023 The mke2fs program now creates filesystems that have the filetype and
2024 sparse_superblock features enabled by default, unless it is run on a
2025 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
2026 so there is now a new flag -O which allows the user to specify with
2027 which features she would like to create the filesystem; "mke2fs -O
2028 none" will create a filesystsem compatible with 2.0 kernels.
2030 The tune2fs program now has a -O option which allows the user to set
2031 and reset "safe" filesystem features. Currently, the only ones which
2032 allows to be modified are the filetype and sparse_superblock features.
2033 Note setting or clearing either feature will require running e2fsck on
2034 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
2035 requires that there is enough free space on the filesystem for the
2036 extra superblocks which will be created by e2fsck.)
2038 Debugfs can now set and print filesystem features in the superblock
2039 using the "features" command. Dumpe2fs will print out the complete
2040 set of features when listing the superblock.
2042 Dumpe2fs has new options -f (force) and -h (header-only).
2044 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
2045 message to come up. This could happen when decrementing or
2046 incrementing a link count could result in an overflow.
2048 Fixed a bug in e2fsck where the block count on the lost+found
2049 directory would not be properly incremented when the directory was
2050 expanded to the point where an indirect block needed to be allocated.
2052 E2fsck now makes some additional sanity checks on the superblock to
2053 avoid crashing or giving a memory allocation error if some of the
2054 values in the superblock are unresonable (but the superblock otherwise
2057 Fixed a bug in e2fsck where a very badly corrupted filesystem might
2058 require two passes to completely fix the filesystem. This happened if
2059 an inode claimed blocks that was part of the filesystem metadata
2060 (typically, when garbage was written into an inode table or indirect
2061 block, since this kind of filesystem corruption normally doesn't
2064 On the Alpha, glibc declares st_flags although it isn't actually used;
2065 the configure script was improved to detect this case so that
2066 e2fsprogs can avoid using the non-functional stat field.
2068 The manual pages were updated to use a more consistent formatting
2069 style consistent with standard Unix man pages. Mke2fs's man page
2070 added documentation for a few previously undocumented options.
2072 Fixed minor display bugs in tune2fs and mke2fs.
2077 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
2079 Added features to parse and print feature strings into the e2p library.
2080 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
2082 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
2083 whose directory entries contain proper filetype information if the
2084 filesystem supports it.
2086 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
2087 the directory entry filetype information. This is used to set the
2088 directory entry filetype information if the filesystem supports it.
2090 Fixed a bug in ext2fs_expand_dir() where the block count in a
2091 directory's inode would not be properly incremented when the directory
2092 was expanded to the point where an indirect block needed to be
2096 E2fsprogs 1.15 (July 18, 1999)
2097 ==============================
2099 Add configuration checks so that e2fsprogs will compile cleanly on
2100 Linux 2.3 kernels that have renamed i_version to i_generation.
2102 E2fsck now prints a progress/completion bar (and not just a simple
2103 spinner) if the -C0 option is requested or if it receives a SIGUSR1
2104 signal. Fsck will automatically manage the (potentially muliple)
2105 e2fsck processes to print completion bars if it is given a -C option,
2106 with the right thing happening if multiple filesystems are being
2107 checked in parallel.
2109 Mke2fs now has better automatic hueristics to determine the filesystem
2110 parameters to be used for a particular filesystem. Added a new option
2111 -T which allows the user to specify how the filesystem is to be used,
2112 which helps mke2fs do a better job selecting the filesystem parameters.
2114 Mke2fs now creates revision 1 filesystems by default, and with the
2115 sparse superblock feature enabled. The sparse superblock feature is
2116 not understood by Linux 2.0 kernels, so they will only allow read-only
2117 mounts of filesystems with this sparse superblocks.
2119 Fix bug where if /dev/null couldn't be opened (should never happen),
2120 e2fsck would hang in a tight loop.
2122 Make e2fsck handle the case where /lost+found isn't a directory.
2124 E2fsck now uses mallinfo if it exists to get accurate statistics about
2127 Fix bug in e2fsck where it wouldn't check to see if a disconnected
2128 inode had any problems before connecting it to /lost+found.
2130 Add check to e2fsck so it makes sure that total number of inodes in
2131 the filesystem is a sane number.
2133 Fix fencepost error when clearing an the end of the block bitmap which
2134 caused the last block in the bitmap not to get cleared.
2136 Cleaned up a number of messages in e2fsck:
2137 * The message "Group's #'s copy of the group descriptor..."
2138 was fixed so that the correct number would be displayed.
2139 * Added missing space in the "disk write-protected" error messsage
2140 * Cleaned up the error message printed when a non-interactive
2141 e2fsck needs to abort a check because the filesystem
2142 appears to be mounted.
2144 Added a new command-line utility, uuidgen, which will create and print
2147 Make debugfs's icheck command more robust by checking to make sure an
2148 inode has valid blocks before interarting over the inode's blocks.
2150 UUID generation now uses a random-based scheme whenever possible to
2151 prevent potential privacy problems.
2153 Man pages for all of the UUID functions in the lirbary were added.
2155 Fixed bug in fsck so it won't coredump if a filesystem not in
2156 /etc/fstab is given to it.
2158 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2159 that most of the other mount utilities understands.
2161 Mke2fs will make a filesystem even if it appears mounted if the force
2164 Dumpe2fs has new command-line options which allow a filesystem expert
2165 to specify the superblock and blocksize when opening a filesystem.
2166 This is mainly useful when examining the remains of a toasted
2169 The badblocks program has been updated to display correctly on disks
2170 with large block numbers.
2172 The badblocks program no longer gives spurious errors when errors
2173 occur on non-block boundaries, which is common if the blocksize is
2176 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2177 MKE2FS_SYNC environment variable is set. This is to work around a VM
2178 bug in the 2.0 kernel. I've heard a report that a RAID user was able
2179 to trigger it even using a 2.2 kernel, but hopefully it will not be
2180 needed for most Linux 2.2 users.
2182 Fixed miscellaneous documentation and man pages.
2187 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2188 in e2fsck's pass1.c really should have been static.
2190 The return value of the uuid_compare() function was changed to make it
2191 match with the convetions used by strcmp, memcmp, and Paul Leach's
2192 UUID sample document.
2194 The "make depend" process has now been made more automated; it now
2195 automatically word-wraps the dependencies, and only replaces source
2196 Makefile.in if there has been a change in the dependencies. Also, a
2197 top-level "make depend" now recurses through all the subdirectories
2200 The Makefile in .../util has been changed so that subst is built using
2201 the native C compiler during a cross-compilation, since the subst
2202 program is only used during the build process. Also add an explicit
2203 rule to build util/subst by cd'ing to the correct directory and
2206 The man directories are defined in terms mandir, so that the configure
2207 script can override the location of the manual pages.
2209 The config files have been updated to recognize new machine types for
2210 both the i386 and alpha families.
2212 Fsck has been modified so that it will accurately create an
2213 fsck_instance even when the noexecute flag is set. This allows for
2214 accurate debugging of the fsck pass structure. Also, when the verbose
2215 flag is given twice, fsck will print debugging information about when
2216 fsck is waiting for jobs to finish.
2219 E2fsprogs 1.14 (January 9, 1999)
2220 ================================
2222 Fix the fstab parsing code so that it can handle blank lines and
2223 comment characters. Also, missing pass numbers need to be treated as
2226 Fixed a bug in e2fsck where under some circumstances (when e2fsck
2227 needs to restart processing after fixing an egregious inconsistency)
2228 it would try to access already freed memory.
2230 E2fsck now prints non-printable characters in directory entries and
2231 pathnames using '^' and 'M-' notation.
2233 Fixed chattr so that it will ignore symbolic links when doing
2234 recursive descent traversals. For both chattr and lsattr, no longer
2235 print the version string unless the -V option is given.
2237 Allow the system administrator to directly specify the number of
2238 inodes desired in the filesystem, for some special cases where this is
2241 Fix portability problems so that e2fsprogs can be compiled under Linux
2242 1.2 systems and Solaris systems.
2244 Update the config.guess file with a more recent version that will
2245 identify newer Linux platforms.
2250 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2251 an inode number of zero is passed to them.
2253 E2fsprogs 1.13 (December 15, 1998)
2254 ==================================
2256 Fixed a bug in debugfs where an error messages weren't getting printed
2257 when the ext2 library routines to read inodes returned errors in the
2258 stat, cmri and rm commands.
2260 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2261 provided, it won't create an inode table smaller than the minimum
2262 number of inodes required for a proper ext2 filesystem.
2264 Fsck now parses the /etc/fstab file directly (instead of using
2265 getmntent()), so that it can distinguish between a missing pass number
2266 field and pass number field of zero. This caused problems for
2267 diskless workstations where all of the filesystems in /etc/fstab have
2268 an explicit pass number of zero, and fsck could not distinguish this
2269 from a /etc/fstab file with missing pass numbers.
2271 E2fsck will create a /lost+found directory if there isn't one in the
2272 filesystem, since it's safer to create the lost+found directory before
2275 Fixed e2fsck so that it would detect bogus immutable inodes which
2276 happen to be sockets and FIFO files, and offer to clear them.
2278 If a filesystem has multiple reasons why it needs to be checked, and
2279 one of the reasons is that it is uncleanly mounted, e2fsck will print
2280 that as the reason why the filesystem is being checked.
2282 Cleaned up the output routines of mke2fs so that it doesn't overflow
2283 an 80 column display when formating really big filesystems.
2285 Added a sanity check to e2fsck to make sure that file descriptors 0,
2286 1, 2 are open before opening the hard disk. This avoids a problem
2287 where a broken program might exec e2fsck with those file descriptors
2288 closed, which would cause disastrous results if the kernel returns a
2289 file descriptor for the block device which is also used by FILE *
2292 Fixed up the e2fsck progress reporting functions so that the values
2293 reliably reach 100% at the completion of all of the e2fsck passes.
2295 Fixed minor documentation bugs in man pages and usage messages.
2300 Fixed a number of lint warnings in the ext2fs library and potential
2301 portability problems from other OS's header files that might define
2302 CPP macros for names like "max" and "min".
2304 ext2fs_badblocks_list_add() has been made more efficient when it needs
2305 to grow the bad blocks list.
2307 Fixed a bug in e2fsck which caused it to dereference a freed pointer
2308 just before exiting.
2310 Fixed the substition process for generating the mk_cmds and compile_et
2311 scripts so that they will work outside of the build tree.
2313 Add sanity check to e2fsck so that if an internal routine
2314 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2315 and causing a core dump. This should never happen, but...
2317 E2fsprogs 1.12 (July 9, 1998)
2318 ==================================
2320 E2fsprogs now works with glibc (at least with the version shipped wtih
2321 RedHat 5.0). The ext2fs_llseek() function should now work even with
2322 i386 ELF shared libraries and if llseek() is not present. We also
2323 explicitly do a configure test to see if (a) llseek is in libc, and
2324 (b) if llseek is declared in the system header files. (See standard
2325 complaints about libc developers don't understand the concept of
2326 compatibility with previous versions of libc.)
2328 The ext2fs library now writes out the block group number in each of
2329 the superblock copies. This makes it easier to automatically
2330 determine the starting block group of the filesystem when the block
2331 group information is trashed.
2333 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
2334 which means that e2fsprogs will ignore the high 8 bits of the
2335 directory entry's name_len field, so that it can be used for other
2338 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2339 E2fsprogs will now support filesystems with 64-bit sized files.
2341 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2343 Added new program "e2label", contributed by Andries Brouwer. E2label
2344 provides an easy-to-use interface to modify the filesystem label.
2346 Fixed bug so that lsattr -v works instead of producing a core dump.
2348 Fixed a minor bug in mke2fs so that all groups with bad superblock
2349 backup blocks are printed (not just the first one).
2351 Mke2fs will check the size of the device, and if the user specifies a
2352 filesystem size larger than the apparent size of the device it will
2353 print a warning message and ask if the user wants to proceed.
2355 E2fsck has a new option -C, which sends completion information to the
2356 specified file descriptor. For the most part, this is intended for
2357 programs to use, although -C 0 will print a spinning character to the
2358 stdout device, which may be useful for users who want to see something
2359 happening while e2fsck goes about its business.
2361 Fixed a bug in e2fsck which could cause a core dump when it needs to
2362 expand the /lost+found directory, and sometimes the bitmaps haven't
2363 been merged in. Also fixed a related bug where ext2fs_write_dir_block
2364 was used to write out a non-directory block. (Which would be bad on a
2365 non-Intel platform with byte swapping going on.)
2367 Fixed bug in e2fsck where it would print a "programming error" message
2368 instead of correctly identifying where a bad block was in used when
2369 the bad block was in a non-primary superblock or block group
2370 descriptor. Also fixed a related bug when sparse superblocks are in
2371 use and there is a bad block where a superblock or block group
2372 descriptor would have been in a group that doesn't include a
2375 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2376 the block group descriptor table is corrupt, it was possible to try to
2377 allocate a huge array, fail, and then abort e2fsck.
2378 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2379 and subsitutes reasonable values if the descriptors are obviously bogus.
2381 If e2fsck finds a device file which has the immutable flag set and the
2382 i_blocks beyond the normal device number are non-zero, e2fsck will
2383 offer to remove it, since it's probably caused by garbage in the inode
2386 When opening a filesystem, e2fsck specially checks for the EROFS error
2387 code, and prints a specific error message to the user which is more
2390 If the filesystem revision is too high, change the e2fsck to print
2391 that this is either because e2fsck is out of date, or because the
2392 superblock is corrupt.
2394 E2fsck now checks for directories that have duplicate '.' and '..'
2395 entries, and fixes this corruption.
2397 E2fsck no longer forces a sync of the filesystem (with attendant sleep
2398 calls) at all times. The ext2fs_flush() function now performs a sync
2399 only if it needed to write data blocks to disk.
2401 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2402 certain errors would not be properly reported.
2404 Updated and expanded a few points in the man pages which users
2405 complained wheren't explicit enough.
2407 Added special case byte-swapping code if compiling on the PowerPC, to
2408 accomodate the strange big-endian variant of the ext2 filesystem that
2409 was previously used on the PowerPC port.
2415 Removed C++ keywords from the ext2fs libraries so that it could be
2418 E2fsck's internal organization has now been massively reorganized so
2419 that pass*.c don't have any printf statements. Instead, all problems
2420 are reported through the fix_problem() abstraction interface. E2fsck
2421 has also been revamped so that it can be called as a library from a
2424 Added new fileio primitives in libext2fs for reading and writing
2425 files on an unmounted ext2 filesystem. This interface is now used by
2428 Added a new libext2fs function for mapping logical block numbers of
2429 a file to a physical block number.
2431 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2432 a block, zeros it, and updates the filesystem accounting records
2435 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2436 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2438 The libext2fs functions now use a set of memory allocation wrapper
2439 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2440 instead of malloc, free, and resize. This makes it easier for us to
2441 be ported to strange environments where malloc, et. al. aren't
2442 necessarily available.
2444 Change the libext2fs fucntion to return ext2-specific error codes
2445 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2446 and depending on the existence of system error codes (such as EEXIST
2449 Renamed io.h to ext2_io.h to avoid collision with other OS's header
2452 Add protection against ext2_io.h and ext2fs.h being included multiple
2455 The types used for memory lengths, etc. have been made more portable.
2456 In generla, the code has been made 16-bit safe. Added Mark
2457 Habersack's contributed DOS disk i/o routines.
2459 Miscellaneous portability fixes, including not depending on char's
2462 The io_channel structure has a new element, app_data, which is
2463 initialized by the ext2fs routines to contain a copy of the filesystem
2466 ext2fs_check_directory()'s callback function may now return the error
2467 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2468 really do the checking, despite the presence of the callback function.
2471 E2fsprosg 1.11 (June 17, 1997)
2472 ==============================
2474 Fixed e2fsck to detect (previously ignored) conflicts between the
2475 superblock or block group descriptors and block bitmaps, inode
2476 bitmaps, and inode tables.
2478 Fixed bug in e2fsck so that when the message printed out when a block
2479 or inode bitmap conflicts with other data, it has the correct group
2482 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2483 to badblocks. This meant that not all of the filesystem was being
2484 tested for bad blocks!
2486 Fixed an array boundary overrun case which cropped up in
2487 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2490 Adjusted the number of columns printed by mke2fs when displaying the
2491 superblock backups to avoid running over 80 columns when making a
2492 really big filesystem.
2494 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2495 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2496 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2501 Fixed install rule in lib/ss so that ss_err.h is actually getting
2504 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2505 bassed back to the caller.
2507 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2508 setting the current inode number (which meant this function wasn't
2511 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2512 blocks in the bitmap when increasing the size of the bitmap.
2514 Changed the initial number of blocks allocated by ext2fs_init_dblist()
2515 to be more realistic.
2517 Added a new function ext2fs_allocate_group_table, which sets up the
2518 group descriptor information (and allocates inode and block bitmaps,
2519 and inode tables for a particular group). The function was created by
2520 factoring out code form ext2fs_allocate_tables().
2522 Added a new function ext2fs_move_blocks which takes a bitmap of the
2523 blocks to be moved, and moves them to another location on the
2526 Make the unix_io channel's io_channel_flush implementation calls sync()
2527 to to flush the kernel buffers to disk.
2529 Added a new function ext2fs_dblist_count returns the number of
2530 directory blocks in dblist.
2533 E2fsprogs 1.10 (April 24, 1997)
2534 ===============================
2536 Mke2fs once again defaults to creating revision #0 filesystems, since
2537 people were complaining about breaking compatibility with 1.2 kernels.
2538 Warning messages were added to the mke2fs and tune2fs man pages that
2539 the sparse superblock option isn't supported by most kernels yet (1.2
2540 and 2.0 both don't support parse superblocks.)
2542 Added new flag to mke2fs, -R <raid options>, which allows the user to
2543 tell mke2fs about the RAID configuration of the filesystem. Currently
2544 the only supported raid option is "stride" which specifies the width
2547 Fixed bug in e2fsck where pass1b would bomb out if there were any
2548 blocks marked bad in the inode table.
2550 Fixed rare bug in mke2fs where if the user had a very unlucky number
2551 of blocks in a filesystem (probability less than .002) the resulting
2552 filesystem would be corrupt in the last block group.
2554 Fixed bug where if e2fsck tried to allocate a block to fix a
2555 filesystem corruption problem and the filesystem had no free blocks,
2556 ext2fs_new_block() would loop forever.
2558 The configure script now checks explicitly to see if "-static" works,
2559 since that can't be assumed to be true --- RedHat doesn't install
2560 libc-static by default.
2562 Fixed bug in libext2's block iterator functions where under some
2563 cirmcustances, file with holes would cause the bcount parameter to the
2564 callback function to be incorrect. This bug didn't affect any of
2565 e2fsprogs programs, but it was discovered by Paul Mackerras, the
2566 author of the PPC boot loader.
2568 Removed use of static variables to store the inode cache in libext2fs.
2569 This caused problems if more than one filesystem was accessed via
2570 libext2fs (static variables in libraries are generally a bad idea).
2571 Again, this didn't affect e2fsprogs programs, but it was discovered by
2574 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
2575 will compile cleanly with 1.2.13 kernels (even with a.out shared
2581 Added new functions to duplicate an ext2 filesystem handle, and its
2582 associated substructure. New functions: ext2fs_dup_handle(),
2583 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
2584 Other structures, such as the io_channel and the inode_cache, now have
2585 a ref count so that they only get freed when they are no longer used
2586 by any filesystem handle. (These functions were added as part of the
2587 development effort for an ext2 resizer).
2589 E2fsprogs 1.09 (April 14, 1997)
2590 ===============================
2592 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
2593 accidentally introduced in the 1.08 release. The overhead calculation
2594 was accidentally removed, which caused ext2fs_initialize() to not
2595 notice when the filesystem size needed to be adjusted down because
2596 there wasn't enough space in the last block group.
2598 Fixed bug in version parsing library routine; it was always parsing
2599 the library version string, instead of using the passed-in string.
2601 Clarified chattr man page.
2603 E2fsprogs 1.08 (April 10, 1997)
2604 ===============================
2606 E2fsck 1.07 was very slow when checking very large filesystems with a
2607 lot of files that had hard links (i.e., news spools). This was fixed
2608 by seriously revamping the icount abstraction. Added a formal test
2609 suite for the icount abstraction.
2611 Debugfs now has a "-l" option to the "ls" command, which lists the
2612 inode number, permissions, owner, group, size, and name of the files
2615 Fix a bug in e2fsck where when a directory had its blocks moved to
2616 another location during the pass 1b processing, the directory block
2617 list wasn't updated, so pass 2 wouldn't check (and correct) the
2618 correct directory block.
2620 E2fsck will now treat inodes which contain blocks which are claimed by
2621 the filesystem metadata by treating them as multiply claimed blocks.
2622 This way, the data in those blocks can be copied to a new block during
2623 the pass 1b--1d processing.
2625 E2fsck will attempt to determine the correct superblock number and
2626 display it in the diagnostic and warning messages if possible.
2628 Add support for a new (incompatible) feature, "sparse_super". This
2629 feature reduces the number of blocks which contain copies of backup
2630 superblocks and block group descriptors. (It is only an incompatible
2631 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
2632 support a new -s option; e2fsck will recognize filesystems built with
2633 this feature turned on.
2635 E2fsck now checks the library to make sure is the correct version,
2636 using new library functions. (This helps to diagnose incorrectly
2637 installed e2fsprogs distributions.)
2639 Dumpe2fs now prints more information; its now prints the the
2640 filesystem revision number, the filesystem sparse_super feature (if
2641 present), the block ranges for each block group, and the offset from
2642 the beginning of the block group.
2644 Mke2fs now distributes the inode and block bitmap blok so that the
2645 won't be concentrated in one or two disks in RAID/striping setups.
2646 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
2647 choose the largest blocks per group that be chosen. (For 2k blocks,
2648 you can have up to 16384 blocks/group; for 4k blocks, you can have up
2649 to 32768 blocks/group.) Previously mke2fs would not allow
2650 specification of more than 8192 blocks per group, even if you were
2651 using a 2k or 4k block group.
2656 Added a new function ext2fs_create_icount2() which takes a "hint"
2657 argument. This hint argument presets the icount array with the list
2658 of inodes which actually need to be in the icount array. This really
2659 helps to speed up e2fsck.
2661 Added a new function ext2fs_icount_validate() which checks the rep
2662 invariant for the icount structure. This is used mostly for testing.
2664 The error mesasage given when a bad inode number is passed to
2665 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
2666 EXT2FS_UNMARK_ERROR).
2668 Added a new function ext2fs_set_dir_block which sets the block of a
2669 dblist entry, given the directory inode and blockcnt.
2671 Added a new function ext2fs_get_library_version() which returns the
2672 current library version, and ext2fs_parse_version_string() which
2673 returns a version number based on a e2fsprogs version string.
2675 The icount functions will return EINVAL if the passed in inode number
2678 E2fsprogs 1.07 (March 9, 1997)
2679 ==============================
2681 E2fsck is now uses much less memory when checking really large
2682 filesystems (or rather, filesystems with a large number of inodes).
2683 Previously a filesystem with 1 million inodes required 4 megabytes of
2684 memory to store inode count statistics; that storage requirement has
2685 now been reduced to roughly half a megabyte.
2687 E2fsck can now properly deal with bad blocks appearing inside the
2688 inode table. Instead of trying to relocate the inode table (which
2689 often failed because there wasn't enough space), the inodes in the bad
2690 block are marked as in use.
2692 E2fsck will automatically try to use the backup superblocks if the
2693 primary superblocks have a bad magic number or have missing meta-data
2694 blocks (or meta-data blocks which are out of range).
2696 E2fsck's pass 3 has been made more efficient; most noticeable on
2697 filesystems with a very large number of directories.
2699 Completely revamped e2fsck's system of printing problem reports. It
2700 is now table driven, to make them more easily customizeable and
2701 extendable. Error messages which can be printed out during preen mode
2702 are now one line long.
2704 Fixed e2fsck's filesystem swapping code so that it won't try to swap
2705 fast symbolic links or deleted files.
2707 Fixed e2fsck core dumping when fixing a filesystem which has no
2708 directories (not even a root directory).
2710 Added a check to e2fsck to make sure that the length of every
2711 directory entry is a multiple of 4 (since the kernel complains if it
2714 Added a check to e2fsck to make sure that a directory entry isn't a
2715 link to the root directory, since that isn't allowed.
2717 Added a check to e2fsk to now make sure the '.' and '..' directory
2718 entries are null terminated, since the 2.0 kernel requires it.
2720 Added check to write_bitmaps() to make sure the superblock doesn't get
2721 trashed if the inode or block bitmap is marked as being block zero.
2723 Added checking of the new feature set fields in the superblock, to
2724 avoid dealing with new filesystem features that this package wasn't
2727 Fixed a fencepost error in ext2fs_new_block() which would occasionally
2728 try to allocate a block beyond the end of a filesystem.
2730 When the UUID library picks a random IEEE 802 address (because it
2731 can't find one from a network card), it sets the multicast bit, to
2732 avoid conflicting with a legitimate IEEE 802 address.
2734 Mke2fs now sets the root directory's owner to be the real uid of the
2735 user running mke2fs. If the real uid is non-zero, it also sets
2736 the group ownership of the root directory to be the real group-id of
2737 the user running mke2fs.
2739 Mke2fs now has more intelligent error checking when it is given a
2740 non-existent device.
2742 When badblocks is given the -vv option, it now updates the block that
2743 it is currently testing on every block.
2745 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
2746 currently correctly if PATH wasn't already set.
2748 Shared libraries now built with dependencies. This allows the shared
2749 library files to be used with dlopen(); it also makes the transition
2750 to libc 6 easier, since ld.so can tell which libc a particular shared
2751 library expects to use.
2756 Added new abstraction (defined in dblist.c) for maintaining a list of
2757 blocks which belongs to directories. This is used in e2fsck and other
2758 programs which need to iterate over all directories.
2760 Added new functions which test to see if a contiguous range of blocks
2761 (or inodes) are available. (ext2fs_*_bitmap_range).
2763 Added new function (ext2_inode_has_valid_blocks) which returns true if
2764 an inode has valid blocks. (moved from e2fsck code).
2766 Added new function (ext2fs_allocate_tables) which allocates the
2767 meta-data blocks as part of initializing a filesystem. (moved from
2770 Added a new I/O manager for testing purposes. It will either allow a
2771 program to intercept I/O requests, or print debugging messages to
2772 trace the activity of a program using the I/O manager.
2774 The badblocks_list functions now store the bad blocks in a sorted
2775 order, and use a binary search to speed up badblocks_list_test.
2777 The inode scan function ext2fs_get_next_inode() may now return a soft
2778 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
2779 those cases where part of an inode table is missing or there is a bad
2780 block in the inode table.
2782 Added a new function (ext2fs_block_iterate2) which adds new arguments to
2783 the callback function to return a pointer (block and offset) to the
2784 reference of the block.
2786 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
2787 application to jump to a particular block group while doing an inode
2790 The badblocks list functions were renamed from badblocks_* to
2791 ext2fs_badblocks_*. Backwards compatibility functions are available
2792 for now, but programs should be modified to use the new interface.
2794 Some of the library functions were reorganized into separate files to
2795 reduce the size of some programs which statically link against the
2798 Put in some miscellaneous fixes for the Alpha platform.
2801 E2fsprogs 1.06 (October 7, 1996)
2802 ================================
2804 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
2805 smash the backup copies in ext2fs_close(). (The problem was that when
2806 e2fsck -p discovered the problem, while it was closing the filesystem
2807 and exiting, it was also blowing away the backup superblocks on the
2808 disk, which was less than friendly.) We now make it the case that we
2809 only write out the backup superblock and the back block descriptors if
2810 the filesystem is completely free from problems.
2812 Fixed a bug in block_interate in the lib/ext2fs library which caused
2813 e2fsck to fail on GNU Hurd-created filesystems.
2815 Add support for Linux/FT's bootloader, which actually uses
2816 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
2819 Add support for the "A" (no atime update) attribute. (Note: this
2820 attribute is not yet in production kernels.)
2822 The test suite is not automatically run when doing a "make all" from
2823 the top level directory. Users should manually run "make check" if
2824 they wish to run the test suite.
2826 Upon a preenhalt(), make the printed message more explicit that
2827 running e2fsck "MANAULLY" means without the -p or -a options.
2829 In e2fsck, if a disconnected inode is zero-length, offer to clear it
2830 instead of offering to connect it to lost+found.
2832 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2833 e2fsck to be run over it, change e2fsck to explicitly display this
2836 For dumpe2fs and e2fsck, cause the -V option to print out which
2837 version of the ext2fs library is actually getting used. (This will
2838 help detect mismatches of using a 1.06 utility with a 1.05 library,
2844 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2845 the naming convention.
2847 In ext2fs_initialize(), make sure the description for the inode bitmap
2848 is correctly initialize.
2850 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
2852 E2fsprogs 1.05 (September 7, 1996)
2853 ==================================
2855 Add support for new fields in the ext2 superblock --- volume name,
2856 volume UUID, and last mounted field. Dumpe2fs displays these fields,
2857 tune2fs and mke2fs allows you to set them. E2fsck will automatically
2858 generate a UUID for those volumes that don't have them.
2860 Put in support for e2fsck to recognize HURD specific ext2 features ---
2861 most notably, the translator block. The e2fsprogs tools will now use
2862 the creator_os field in the superblock to correctly handle different
2863 OS-specific variants of the ext2 filesystem.
2865 E2fsck now fixes inodes which have a the deletion time set, but which
2866 have a non-zero i_link_count field by offering to clear the deletion
2867 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2868 ext2 kernel behavior) and offered to unlink the file.
2870 If e2fsck sets the clean bit, but nothing else, set the exit code
2871 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2872 set the filesystem valid bit when it was previously cleared. :-) This
2873 was needed to make the HURD fsck driver happy.
2875 If the user refuses to attach an unattached inode, e2fsck will no
2876 longer set the inode's link count. Otherwise, the inode would end up
2877 getting marked as unused, which might cause loss of data later.
2879 Make the message issued by e2fsck when the superblock is corrupt less
2880 confusing for users. It now mentions that another reason for the
2881 "corrupt superblock" message might be that the partition might not be
2882 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2884 Make the libext2 library more robuest so that e2fsck won't coredump on
2885 an illegal superblock where the blocksize is zero. (f_crashdisk is
2888 By default, create filesystems where the default checkinterval is 6
2889 months (180 days). Linux servers can be robust enough that 20 reboots
2890 can be a long, long time.
2892 Added configure flag --enable-old-bitops, which forces the bitops to
2893 use the old (native) bitmask operations. By default on the sparc
2894 platform, the standard ext2 bit ordering is now used.
2896 Added a new feature to e2fsck to byte-swap filesystems; this can be
2897 used to convert old m68k filesystems to use the standard byte-order
2898 storage for the superblock, inodes, and directory blocks. This
2899 function is invoked by using the '-s' option to e2fsck.
2901 Debugfs's "dump" command has been enhanced so that it writes out the
2902 exact size of the file so that the nulls at the end of the file are
2903 eliminated. The command also accept a new "-p" option which will
2904 attempt preserve to preserve the ownernship, permissions, and
2905 file modification/access times.
2907 Debugfs has two new options, -f and -R. The -R option allows the user
2908 to execute a single debugfs command from the command line. The -f
2909 option allows the user to specify a "command file" containing debugfs
2910 commands which will get executed.
2912 Dumpe2fs now pretty prints the check interval, instead of just
2913 printing the check interval as a number of seconds.
2915 Fix bugs in debugfs: the params command when no filesystem is opened
2916 no longer causes a core dump. It is now possible to unlink a file
2917 when a pathame containing a '/' is specified.
2919 Tune2fs has a new -C option which sets the number of times the
2920 filesystem has been mounted.
2922 Fix the chattr '-v' option so that it actually works. Chattr was
2923 being buggy about the -v option parsing.
2928 The directory lib/uuid contains a set of library routines to generate
2929 DCE compatible UUIDs.
2931 Extended ext2fs_namei() to handle symbolic links. Added new function
2932 ext2fs_nami_follow() which will follow last symbolic link in the case
2933 where the pathname points to a sym link.
2935 The ext2fs_block_iterate function will now return the HURD translator
2936 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2937 iterator to return data blocks only. The ext2fs.h file now defines
2938 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2939 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2940 count field of the iterator callback function.
2942 The test script driver now takes an optional second argument, which is
2943 the test case to be run. This allows you to run a test case without
2944 needing to run the entire test suite.
2946 On Linux ELF systems, install the .so files in the correct places
2947 (/usr/lib). The .so files must be stored in the same directory as the
2950 Fixed miscellaneous HURD compilation issues with header file being
2951 included in the right order.
2953 Fixed debugfs so that it resets optind to zero, not one, since setting
2954 optind to zero is more correct.
2957 E2fsprogs 1.04 (May 16, 1996)
2958 =============================
2960 First "official" (1.03 was a limited release only) to support building
2961 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2964 This package includes a RPM specs file, that it can be built using the
2965 RedHat Package Manager.
2967 E2fsck now prints a hint that if there are lots of incorrectly located
2968 inode bitmaps, block bitmaps, and inode table blocks, the user might
2969 want to try using e2fsck -b 8193 first, to see if that fares any
2972 For ext2 filesystem written with the hurd, debugfs will now print out
2973 the translator field when printing an inode structure.
2975 Lots of miscellaneous linking/installation cleanups:
2977 Libraries are now linked using a relative pathname, instead of
2978 relying on -L working correct. It doesn't, in many cases, including
2979 current versions of GNU ld. This guarantees that the build tree is
2980 linking with the right libraries, instead of the ones installed in
2983 Header files, man pages, and the et/ss shell scripts are now
2984 generated using a custom substitution script, instead of relying on
2985 the configure script. This prevents needless recompilation of
2986 files; in addition, the custom substitution script is much faster.
2988 e2fsck may now be linked dynamically, by using the
2989 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2990 since it increases e2fsck's dependence on other files, but some
2991 people need to save disk space, and other critical programs on their
2992 systems were being linked dynamically anyway.
2994 Programs such as fsck which didn't need to be linked against
2995 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2996 only link against libraries they actually need. Otherwise, those
2997 programs would require the presense of libraries that otherwise
2998 could be removed from a rescuse diskette.
3000 The ss include files are now installed correctly so they can
3001 actually be used by another package.
3003 If the profiling libraries are built, they are now installed on a
3004 "make install-libs".
3007 E2fsprogs 1.03 (March 27, 1996)
3008 ===============================
3010 Change the m68k bit numbering for bitmasks to match the bit numbering
3011 used by all other ext2 implementations. (This change was requested by
3012 the m68k kernel development team.)
3014 Support (in-development) filesystem format revision which supports
3015 (among other things) dynamically sized inodes.
3017 Fixed a bug in the ext2 library so that an intelligent error is
3018 returned if mke2fs is run with a ridiculously small number of blocks
3021 Fixed a bug in the ext2 library which required that the device be
3022 openable in read/write mode in order to determine its size. This
3023 caused e2fsck -n to require read/write access when it was not
3024 previously necessary.
3026 Fixed a bug in e2fsck which casued it to occasionally fail the test
3027 suite depending on which version of the floating point library it was
3030 Fixed a bug in e2fsck so that it now halts with a fatal error when
3031 certain superblock consistency checks fail. Previously it continued
3032 running e2fsck, with some potential confusing/damaging consequences.
3034 Added new flag to fsck which allows the root to be checked in parallel
3035 with other filesytems. This is not the safest thing in the world to
3036 do, but some system administrators really wanted it.
3038 Fixed -Wall flames in lib/ss.
3041 E2fsprogs 1.02 (January 16, 1996)
3042 =================================
3044 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
3046 Change e2fsck to print statistics of how many non-contiguous files are
3047 on the system. Note that a file which is larger than 8k blocks, it is
3048 guaranteed to be non-contiguous.
3050 In mke2fs, print a warning message if a user tries to format a whole
3051 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
3052 whole disk, the -F (force) option forces mke2fs to format a whole disk
3055 Fix a bug in fsck where in some cases it might start checking
3056 partitions in the next pass before it finishes checking partitions in
3057 the current pass. This still won't cause two partitions on the same
3058 disk will be checked, so it's rarely a problem in real life.
3060 Patch lsattr so that it won't hang when checking a named pipe.
3062 Minor compilation fixes:
3063 * Fix the order of libraries that were linked in debugfs.
3064 * Allow the sources to be compiled with -ansi turned on.
