Theodore Ts'oc6633052002-09-24 01:26:50 -04001E2fsprogs 1.29 (September 24, 2002)
2===================================
3
4Fixed a bug in e2fsck which could corrupt a directory when optimizing
5it (via the -D option) or rebuiliding the hash tree index with a 1 in
6512 probability, due to a fence post error.
7
8Fixed a bug in the LVM support code which caused LABEL='xxx' not to
9work correctly.
10
11Mke2fs now enables the directory indexing flag by default. (Since
12this is a compatible feature flag, it's safe to do so.)
13
14Tune2fs will support setting the directory indexing feature flag. It
15will automatically set up the default hash algorithm and hash seed
16fields in the superblock.
17
18If the bone-headed user enters the root filesystem twice in
19/etc/fstab, the -R option which skips the root filesystem will skip
20all of them. (Addresses Debian bug #159423). Note! This is not a
21precedent for dealing intelligently with any other kind of doubled
22entry in /etc/fstab!
23

25Programmer's notes:
26-------------------
27
28Removed perror declaration in lib/et/internal.h. All modern systems
29can be expected to define perror() these days. Besides, the lib/et
30code wasn't using perror at all anyway. :-)

Theodore Ts'ob7bad612002-08-31 03:00:33 -040033E2fsprogs 1.28 (August 31, 2002)
34================================
35
36Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
37for setting the htree flag is not included yet, although it can be
38manually turned on via the debugfs program.
39
40Clarified e2fsck error message which is printed when it cannot find
41sufficient contiguous block when relcating filesystem metadata.
42
43Added support for building an EVMS plugin module for ext2/3. This
44module is substantially the same as the EVMS module shipping with EVMS
451.1, with one or two bugfixes. E2fsprogs can also build this plugin
46for use with EVMS 1.0 (which did not include the ext2 plugin module),
47if the configure --enable-old-evms flag is given.
48
49Fsck will search through EVMS volumes when trying to resolve
50filesystem specifications such as LABEL=xxx or UUID=xxx.
51
52Added a new utility program, /sbin/findfs, which will return
53filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
54the device name.
55
56Update and clarified various man pages. (addresses Debian Bug #145044,
57#146437, #131350, #151990, #144621, #141938)
58
59If there are no filesystems specified on fsck's command line, fsck now
60treat that as if the -As options were given. Previously it would
61simply do nothing. (Addresses Debian Bug #153102)
62
63Mke2fs no longer treats a failure to be able to clear the MD signature
64at the end of the filesystem as a fatal error. (Addresses Debian Bug
65#155007)
66
67The e2p library functions (which are used by lsattr and chattr) now
68double check to make sure the file is a regular file or directory
69before attempting to use the ext2 ioctls. Some device drivers
70unfortunately respond to the ext2 ioctl's with unknown behaviour.
71(Addresses Debian Bug #152029).
72
73The extended attribute handling has been updated to correspond with
74the latest V2 bestbits ACL code.
75
76Fixed bug in e2fsck which caused it to not clear the dtime field when
77processing truncated inodes on the orphan list. This could cause data
78loss(!) if a filesystem is rebooted before a truncate has been
79committed.
80
81E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
82algorithms. This makes e2fsck much faster in the case of severely
83corrupted filesystems where a large number of blocks are claimed by a
84large number of inodes. (Thanks to the 2.5 IDE device driver for
85inspiring this work.)
86
87Resize2fs has been significantly sped up when shrinking and expanding
88a filesystem by a very small number of blocks (for example, when EVMS
89is converting a partition to be an EVMS legacy volume).
90
91Added a new option to e2fsck, -D, which will optimize or compress all
92of the directories in the filesystem.
93
94E2fsck now catches SIGINT and SIGTERM to make sure it will can
95properly clean up and only exit at safe points. Fsck will pass
96SIGINT/SIGTERM to its child processes, and wait until they have all
97exited before it exits.
98
99The uuid parsing code in the uuid library now properly complains when
100an illegally formated uuid is presented to it. (Addresses Debian bug
101#152891)
102
103Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
104and 2.4.17, since the workaround can cause problems when using a 2.4
105kernel with an old version of glibc built with the 2.2 headers.
106
107Fixed a bug in mke2fs where it wasn't properly clearing the initial
108superblock used by other filesystems. (Addresses Debian bug #147256.)
109
110Added support for the synchronous directory feature written by Andrew
111Morton.
112
113The debugfs program can delete directories using the rmdir command.
114
115Add support for 8k and 16k filesystems (for systems with page sizes
116that are greater or equal to 8k or 16k, respectively). Note that
117these filesystems can not be mounted on x86 systems, or other systems
118with only 4k page sizes, due to limitations in the current Linux VM
119code.
120
121Resize2fs requires that the filesystem state be valid and have no
122errors; otherwise, e2fsck -f must be run first. (Previously it simply
123required that the last fsck time be greater than the last mount time.)
124
125Configure now defaults the man pages directory to /usr/share/man on
126Linux systems.
127
128E2fsck now offers to truncate inodes which contain too many blocks (so
129that i_blocks would overflow. Also fixed handling of large sparse
130files.
131
132E2fsck now more completely checks for symlink validity, including
133requiring NULL termination and length checks.
134
135E2fsck will offer to try forcing a disk write to remap a bad block
136after finding a read error when reading a filesystem metadata block.
137
138Fixed a bug in debugfs which caused the -b and -s options to crash
139debugfs, as well as breaking the testb, setb, and clearb functions.
140
141Added a bmap command to debugfs which calculates the logical to
142physical block mapping for a particular inode.
143
144Fixed a bug in code which checked to see if a device was mounted which
145sometimes (rarely) failed in the case of a plain file.
146
147Fixed a bug in resize2fs where when it reported an error, it would
148print a message erroneously indicating that the filesystem had been
149resized before it aborted.
150
151When resizing a plain file which is smaller than the requested size,
152resize2fs will attempt to extended the file so that programs like
153e2fsck will not complain that the file is too small.
154
155Resize2fs will print the actual new size of the filesystem when it is
156finished resizing.
157
158Fixed a bug in debugfs where "ls -l" would report incorrectl file type
159information on big-endian systems.
160
161
162Programmer's notes:
163-------------------
164
165Fixed collisions with C++ reserved words.
166
167Added portability fixes for building e2fsprogs on the HURD and AIX.
168
169Added the ext2ed program for creation of test cases. (ext2ed has many
170limitations and bugs which make it unsuitable for production use.)
171
172The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
173flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
174name_len field is byte swampped on big-endian machines, since in the
175V2 structure, name_len is a char field which is doesn't need to be
176byte swapped --- except if an old-style kernel had byte-swapped the
177name_len field as part of the V1 structure.
178

Theodore Ts'oa8e77242002-03-08 03:12:14 -0500180E2fsprogs 1.27 (March 8, 2002)
181==============================
182
183The warning messages for mke2fs now go to standard error.
184
185Fixed to make sure "make check" runs all of the test programs with
186LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
187
188The mke2fs program checks the boot sector for the BSD disk label, and
189avoids erasing it if it is there.
190
191Fixed a bug in e2fsck which caused it to core dump if the journal
192inode was missing when it was supposed to be there.
193
194E2fsck now prints ranges in pass 5 when printing deltas for the block
195and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500196
197Debugfs's "ls -l" command now will print out the file type information
198in the directory entry.
199
200Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
201mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
202
203Debugfs can now examine the experimental directory indexing
204information.
205
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500206Fixed bug in debugfs which caused it to core dump if modify_inode is
207called without an open filesystem.
208
209The debugfs lsdel command now runs its output through a pager first.
210
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500211When installing manual pages, remove the compressed manual pages first.
212
213Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
214
215Fix the 2.4 resource limitation workaround introduced in 1.26 which
216actually broke things on mips32, sparc32, and Alpha platforms.
217
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500218Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
219(which is required by the newer libintl libraries).
220
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500221Programmer's notes:
222-------------------
223
Theodore Ts'oa8e77242002-03-08 03:12:14 -0500224Fixed various gcc -Wall complaints.
225
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500226Fixed a few memory leaks in the e2fsck journaling code, and in the
227ismounted code checking for a swap device.
228
229Add new inode I/O abstraction interface which exports an inode as
230an I/O object.
231
232Exported ext2_file_flush as a public interface.
233
234In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
235
236Lots of small random portability fixes to make e2fsprogs build under
237AIX --- even without the 5L compatibility toolkit, and even using the
238uber-crippled AIX native C compiler.
239

Theodore Ts'o06987392002-02-03 01:36:54 -0500241E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500242=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500243
Theodore Ts'o446314f2001-12-24 15:22:27 -0500244Dumpe2fs will keep going now if the bad block inode can't be read.
245(Previously it stopped with a fatal error.)
246
247E2fsck will now give an opportunity to run the journal even if the
248recovery flag is not set. This is the default behaviour if e2fsck is
249using a backup superblock, since the needs_recovery flag will never be
250set in the backup superblock copies.
251
252E2fsck now automatically finds the backup superblock/group descriptors
253even when the primary superblock is completely destroyed for 2k and 4k
254filesystems. (Previously it just guessed/assumed that we were dealing
255with a 1k filesystem in that case, and users had to manually specify
256the backup superblock number.)
257
258Fixed a bug in e2fsck where it dereferences a null pointer when there
259is a problem opening a filesystem in preen mode.
260
261E2fsck now handles external journals correctly; previously it trashed
262the external journal device if the journal needed to be replayed.
263
264Work around ulimit incompatibility problem caused by recent 2.4
265kernels; the unix IO module will automatically try to set any resource
266limits to be infinite on startup.
267
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500268Fixed a bug in e2fsck where it wasn't allocating a new block or inode
269bitmap if it wasn't present and the blocksize was 2k or 4k.
270(Addresses Debian Bug #116975)
271
272E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
273clearing the new V2 fields if they do not make sense or if the ext3
274superblock is version 1 superblock.
275
276E2fsck will automatically relocate the ext3 journal from a visible
277file (i.e., /.journal) to an hidden inode if the filesystem has been
278opened read/write. This allows the users to add a journal while the
279filesystem is mounted, but the next time the system is rebooted, the
280journal file will disappear. This avoids problems with backups,
281stupid operators with superuser bits, etc.
282
283Fix a bug in fsck where it would not support a filesystem type of
284"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
285
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500286Fsck now supports fstab entries of the form "ext3,ext2". It will also
287automatically identify reiserfs filesystems.
288
289The number of processes spawned by fsck can now be limited using the
290FSCK_MAX_INST environment variable.
291
Theodore Ts'o446314f2001-12-24 15:22:27 -0500292Fsck now searchs the LVM proc hierarchy to find logical volumes which
293should be searched for UUID and label information.
294
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500295Work around a bug in 2.4.10+ kernels by trying to unset the filesize
296limit if at all possible, when opening a block device. (The filesize
297limit shouldn't be applied against writes to a block device.)
298
Theodore Ts'o446314f2001-12-24 15:22:27 -0500299In mke2fs and e2fsck, specifying the -c option twice will now do
300a read/write test on the disk. Update the man pages to encourage
301using the -c option, and to discouraging running badblocks separately,
302since users tend to forget to set the blocksize when running
303badblocks.
304
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500305Mke2fs now automatically clears the immutable attribute on a
306pre-existing .journal file left over from a previous failed attempt to
307add a journal to an alreadyy-mounted filesystem.
308
309Fixed mke2fs's exit codes to consistently indicate when the mke2fs
310operation failed.
311
Theodore Ts'o446314f2001-12-24 15:22:27 -0500312Mke2fs now creates the lost+found directory with permissions of 0700,
313so that files that had previously lived in protected directory are
314safe if they get dropped in lost+found and the system administrator
315doesn't deal with immediately. (Addresses Debian #bug 118443)
316
317Mke2fs and e2fsck (and all programs that use the
318ext2fs_check_if_mounted function) will now properly identify that a
319device is mounted, even in cases where devfs has confused things with
320multiple devices names with the same identity, or if a dim-witted
321system administrator has done something stupid like creating device
322file aliases in their home directory. Also now checks for swap devices
323by using /proc/swaps. (Addresses Debian bug #106622)
324
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500325Added a new option (-T) to tune2fs which sets the time a filesystem
326was last checked.
327
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500328Speed up e2image when creating sparse raw image files by optimizing
329away excess lseek() system calls.
330
331Fix support of large (> 2GB) files when used as a filesystem in
332mke2fs, tune2fs, debugfs, and findsuper.
333
334Debugfs's stat and icheck commands now properly deals with large (>
3352GB) files.
336
337Debugfs's set_super_value command now prints out the list of valid
338superblock fields which can be set using the command.
339
Theodore Ts'o446314f2001-12-24 15:22:27 -0500340Debugfs's rm and kill_file command now updates the superblock free block
341and inode counts, thus keeping the filesystem consistent.
342
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500343Debugfs's lsdel command now takes an optional argument which allows
344the user to only see the most recently deleted files.
345
346A new command (undel) was added to debugfs which automates
347undeleting a deleted inode and linking it back to a directory.
348
349Debugfs's ls command now takes a new option, -d, which lists
350deleted directory entries.
351
352Debugfs's testb, freeb, setb, and find_free_block commands now take an
353optional count argument.
354
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500355Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
356be used to signal that a particular inode should not be eligible for
357tail-merging --- this is needed for programs like LILO.
358
359The findsuper (an unreleased, uninstalled utility program) has been
360improved to add extra validity checks and to add a progress meter.
361(It is still an unsupported program; the officially supported way to
362recover from a trashed partition table is to use gpart; findsuper is
363for wizards only. :-)
364
365Debugfs was fixed to compile with "configure --disable-swapfs".
366
Theodore Ts'o446314f2001-12-24 15:22:27 -0500367Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500368
369Added new translation file for Turkish.
370
Theodore Ts'o446314f2001-12-24 15:22:27 -0500371Programmer's notes:
372-------------------
373
374Fix general gcc -Wall complaints.
375
376E2fsprogs (mostly) works with the dietlibc.
377
378The programming texinfo file has been expanded to include description
379of additional libext2fs functions. (Still not compeltely done, but a
380lot of the more important functions have been documented.)
381
382Added a umask structure to struct_ext2_filsys, which currently only
383modifies the behaviour of ext2fs_mkdir(), but if we add any file
384creation functions to libext2fs, we should also make sure they respect
385the umask setting.
386
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500387The build-rpm script was fixed to be a bit more safe.
388
389The tests' Makefile now has a way of automating test case creation
390for e2fsck, using "make testnew".
391
392Created a new function, ext2fs_dir_iterate2 which passes more
393information to the callback function (identical to the one used by
394ext2fs_dblist_dir_iterate). The directory iterator functions take a
395new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
396directory entries. If the directory entry is deleted, the callback
397function will be called with the entry paraemter set to
398DIRENT_DELETED_FILE.
399
400Added new functions, ext2fs_inode_alloc_stats and
401ext2fs_block_alloc_stats, which takes updates block/inode allocation
402statistics in the bitmaps, block group descriptors, and superblock
403when inodes or blocks are allocated or deallocated.

Theodore Ts'od08a4ce2001-09-20 09:47:42 -0400406E2fsprogs 1.25 (September 20, 2001)
407===================================
408
409This is primarily a bug-fix release; no new features were added, but
410there are a number of embarassing bug fixes and cleanups applied.
411
412Fix a bug mke2fs which causes stack garbage to be written to disk when
413zapping disk sectors. (This bug could cause mke2fs to core dump for
414some kernels, I suspect with security enhancement patches.)
415
416Remove unneeded #include of <linux/config.h> which was breaking
417building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
418
419Updated tune2fs man page to reflect the fact that adding or removing a
420journal doesn't require running e2fsck.
421
422Remove use of AC_REQUIRE from autoconf which had been used to prevent
423AC_CANONICAL_HOST from being called twice; unfortunately this causes
424recent autoconf to bomb out since they don't allow AC_REQUIRE to be
425used outside of autoconf macros. Fortunately, it doesn't seem to be
426necessary any more, anyway.
427
428E2fsck will now not fall back to an alternate superblock if the user
429specifies the superblock location explicitly on the command-line.
430This allows easier recovery from a situation where the primary
431superblock and block groups are slightly corrupted, but the backup
432superblocks are completely broken.
433
434Fix problem which caused compile_et and mk_cmds to blow up if
435e2fsprogs was in a directory with a pathname that contained spaces.
436
437We are now more paranoid about checking the entry in /etc/mtab to make
438sure the filesystem is really mounted, since some broken distributions
439(read: Slackware) don't initialize /etc/mtab before checking non-root
440filesystems. (Slackware also doesn't check the root filesystem
441separately, and reboot if the root filesystem had changes applied to
442it, which is dangerous and broken, but there's nothing I can do about
443that.)
444
445Make UUID library C++ friendly by adding appropriate extern "C"
446declarations and using const in the function declarations.
447
448Fix up the com_err texinfo file so that it can product a valid info
449file (previously, it could only be used to generate paper
450documentation using texinfo.tex).
451
452
Theodore Ts'ofb707752001-09-04 15:00:37 -0400453E2fsprogs 1.24a (September 2, 2001)
454===================================
455
456Fix brown-paper bug in mke2fs which caused it to segfault when
457printing the version string.

Theodore Ts'o109624a2001-08-31 00:59:55 -0400460E2fsprogs 1.24 (August 30, 2001)
461================================
462
463Revert the BLKGETSIZE64 support, since for some distributions, this
464ioctl has been used by an unofficial kernel patch to update the last
465sector on the disk, and this was causing disk corruption problems as a
466result.
467
468Mke2fs is now more careful about zapping swap space signatures and
469other filesystem/raid superblock magic values so that programs like
470mount who try to use hueristics to determine the filesystem type of a
471partition are less likely to be confused.
472
473E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
474regular file (since Andreas Dilger's on-line resizing tools will set
475its mode bits).
476
477Fixed some minor texinfo, man pages nits for spelling errors,
478texinfo warnings, etc. (Addresses Debian bug #110621.)
479
480E2fsprogs program no longer print the filesystem version number
481(i.e. 0.5b), since it only confuses people and doesn't serve any real
482purpose.
483
484E2fsck will once again compile under libc5, since it will supply its
485own version of strnlen if necesssary.
486
487mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
488when specifying the external journal device. tune2fs will also search
489devices looking for the externla journal debice when removing.
490
491E2fsprogs 1.23 (August 15, 2001)
492================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400493
494Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -0400495correctly handle a filesystem with EA's and check the EA blocks for
496corruptions.
497
Theodore Ts'od494bba2001-08-09 06:14:42 -0400498E2fsck's symlink sanity checking has been cleaned up. It now checks
499the i_size value of fast symlinks, and checks for immutable flags
500being set of symlinks, etc.
501
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400502E2fsck now offers to clear inodes which are special files that have a
503non-zero i_blocks or i_size field. (The i_size field check was in the
504previous version of the code, but due to a bug it didn't offer to
505clear the inode unless i_size and i_size_high were both non-zero.)
506
Theodore Ts'od494bba2001-08-09 06:14:42 -0400507E2image can now create "raw" image files, which only contain the
508filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
509debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -0400510
511Add support for the 64-bit block device patches.
512
513Fixed bugs in creating external journals with a 1k blocksize.
514
Theodore Ts'od494bba2001-08-09 06:14:42 -0400515Add initial support for external journals (so long as the external
516journal only supports a single filesystem) in e2fsck.
517
518Remove requirement for needing to run fsck on a filesystem after
519removing a journal (either internal or external).
520
Theodore Ts'obf16d102001-07-27 22:20:06 -0400521The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400522
523Speed up the check of an ext3 filesystems by avoiding a needless flush
524of all of the superblock and block group descriptors.
525
Theodore Ts'od494bba2001-08-09 06:14:42 -0400526Speed up creating an internal journal using tune2fs in the case where
527the filesystem has a lot blocks already allocated.
528
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400529Tune2fs has been fixed to make sure that only error messages go to
530stderr, and normal message go to stdout. (Addresses Debian bug #108555)
531
Theodore Ts'od494bba2001-08-09 06:14:42 -0400532Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400533now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -0400534
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400535Add support in fsck for the filesystem type "auto".
536
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400537Fsck -A will not try to interpret device names for filesystems which
538have a pass number is 0. (Addresses Debian bug #106696).
539
540Fsck prints a warning message if now valid filesystems are passed to
541it. (Addresses Debian Bug #107458.)
542
Theodore Ts'o9249d982001-07-20 18:14:10 -0400543E2fsck now gives an explicit warning if there filesystem still has
544errors at the end of the run. (Addresses Debian bug #104502)
545
Theodore Ts'od494bba2001-08-09 06:14:42 -0400546E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400547reflects an error. E2fsck will also not run the orphan list if the
548filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -0400549
550E2fsck now prints the number of large files when given the -v option.
551
552Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -0400553
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400554Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -0400555
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400556
Theodore Ts'o19d6b542001-06-23 00:13:09 -0400557E2fsprogs 1.22 (June 22, 2001)
558==============================
559
560Fixed a bug in e2fsck's handling of orphan inodes which are special
561files (i.e., block/character device files, named FIFO's, etc.).
562
563Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
564tune2fs to fail at adding a journal to a mounted filesystem.
565
566Fixed a few big-endian bugs in e2fsprogs
567 * The directory block functions were accidentally reporting
568 some directories as corrupted when they weren't.
569 * If e2fsprogs is compiled --disable-swapfs, the C language
570 equivalents weren't being included for big-endian platforms.
571 (Fixes Debian bug #101686).
572
573Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
574
575Programmer's notes:
576-------------------
577
578Use platform independent method of defining the BLKFLSBUF and FDFLUSH
579ioctls, and allow them to be defined for non-i386 platforms.
580
581The uuid.h header file is now protected against multiple inclusions.
582
583E2fsprogs is now being developed using BitKeeper. Changed the test
584scripts to deal with BK's stripping CR characgters from text files,
585and changed the top-level Makefile.in to avoid including BitKeeper
586files when generating the source tarball.
587
588
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000589E2fsprogs 1.21 (June 15, 2001)
590==============================
Theodore Ts'o767de092001-06-02 01:20:18 +0000591
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000592Added new configure flags which allow a subset e2fsprogs to be built;
593this is most useful for boot floopies, since the resulting shared
594libraries and programs are slimmed down by removing features that
595aren't necessary for a boot floppy. The new flags that were added
596are: --disable-swapfs, which removes support for byte swapping old
597legacy PPC/68k filesystems, --disable-debugfs, which removes support
598for debugfs from the libext2fs library, --disable-imager, which
599removes support for the e2image program, and --disable-resizer, which
600removes support for resize2fs.
601
602E2fsck now prints the number of mounts or days elapsed since the last
603check when e2fsck is forced to check an otherwise clean filesystem.
604
605Tune2fs now prints an informative message about how often a filesystem
606will be checked when adding a journal to the filesystem, to remind the
607user that he/she may want to adjust those parameters using tune2fs
608-c/-i.
609
610Worked around hurd brain-damage which causes e2fsck to sometimes
611believe a filesystem is the root filesystem based on device numbers
612(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
613violation).
614
615Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
616erroneous error with the -F option was specified.
617
618Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000619ext3 0.7a.
620
Theodore Ts'o767de092001-06-02 01:20:18 +0000621Fixed two bugs in e2fsck's handling of dup block handling, dealing
622with relatively uncommon edge cases: a directory with an indirect
623block which is claimed by another file, and when the last inode in the
624filesystem has blocks claimed by another file.
625
Theodore Ts'o5a9c0362001-06-02 04:55:57 +0000626E2fsck now checks to see if the i_size field of a fast symlink is too
627big, and offers to clear the symlink if so.
628
629E2fsck now checks to see if i_size_high of special files is non-zero,
630and offers to clear i_size_high.
631
Theodore Ts'o767de092001-06-02 01:20:18 +0000632Fix e2fsck's handling of incompatible journal flags so that the user
633has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +0000634entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +0000635
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000636Fixed a bug in fsck which could cause it to core dump if a mix of
637standard and non-standard device names are used in /etc/fstab.
638(Debian bug #100559)
639
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000640Fixed a bug in debugfs which caused read errors when copying a file to
641not be noticed.
642
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000643The debugfs set_super_value command can now modify the s_lastcheck field.
644
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000645Fixed a bug in lsattr and chattr which was accidentally introduced in
6461.20 to support > 2GB files; both lsattr and chattr wasn't reading
647directories correctly because the change modified the layout of struct
648dirent to be incompatible with the libe2p shared library.
649
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000650Cleaned up the mke2fs manual page and included a discussion about why
651it's good to periodically check the filesystem even when journaling is
652enabled.
653
Theodore Ts'o767de092001-06-02 01:20:18 +0000654Programmer's notes:
655-------------------
656
657Fix general gcc -Wall complaints.
658
659The types needed by the ext2 header files are now provided by
660lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
661
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000662Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000663in ext2_types.h. Also, if linux/types.h has already been defined,
664don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000665
Theodore Ts'o767de092001-06-02 01:20:18 +0000666Fixed make depend script so that it automatically corrects the
667pathname cleanups performed by make -M, so I don't have to fix them up
668by hand.
669
670Fixed the d_loaddump test case to be more robust, and not depend on
671bash'isms.
672
673Removed debugfs's dependence on pread(), which was accidentally
674intrudced in e2fsprogs 1.20
675
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000676Fixed a performance bug in the libext2fs's icount routine; the size
677estimate of the icount array was incorrectly being calculated.
678
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000679Removed use of the badblocks compatibility functions in the e2fsprogs
680programs.
681
682Added paranoia code which protects against strange cases where /etc
683isn't on the root filesystem, or if /etc/mtab doesn't exist.
684
685The header file ext2_types.h is now installed.
686
687Autoconf is used to determine when we are on big-endian machines,
688instead of doing run-time tests, to save a few bytes of code.
689
690The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
691functions are no longer inline functions, which saves space and
692doesn't really cost any real performance.
693
694The ext2fs library no longer depends on the e2p library. (What need
695there was of it --- namely, fsetflags, was coded in-line).
696
697Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
698when the user is stupid and tries compiling the package using "make
699install" as root.
700
701Miscellaneous code cleanups:
702 * Added missing files from Makefile.in's SRCS file, so that
703 their dependencies would be properly calculated.
704 * Removed redundant code
705 * Fixed comments in code
706 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +0000709E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000710=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +0000711
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000712Add support for replaying the ext3 journal purely in user mode,
713including handling the orphaned inode list. Used code contributed by
714Andreas Dilger, with bug fixes and the orphaned inode handling done
715by Theodore Ts'o.
716
717The mke2fs and tune2fs programs can create or modify a filesystem to
718include an ext3 journal. Tune2fs also can be used to remove an ext3
719journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +0000720
721E2fsck will now check for the existence of a linked list of orphan
722inodes in the superblock, and clear those inodes before starting the
723rest of the filesystem check (but after the journal playback).
724
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000725E2fsck now validates the file descriptor passed to the -C option,
726which saves against the completion bar getting written to an
727unexpected location, such as the disk being checked. (Debian
728bug/wishlist #55220)
729
730E2fsck will now bump the filesystem revision number from zero to one
731if any of the compatibility bits are set.
732
733Fixed a bug where a badly corrupted directory on a big endian system
734could cause e2fsck to die with a bus error. The
735ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
736the ext2 library now does alignment sanity checks on the rec_len field
737of the directory entry before using it.
738
739The ext2 library has been enhanced to make tune2fs safe to run on
740mounted filesystems. (Users could usually get away with using tune2fs
741on mounted filesystems before, but with the advent of ext3 and
742journaling, it became important to make tune2fs was *really* safe for
743use even when the filesystem being modified is mounted.) E2label is
744now implemented by tune2fs using an argv[0] dispatch, so that e2label
745is also now safe for use on mounted filesystems.
746
747Added a new program, e2image, which creates a backup of critical ext2
748filesystem data structures. The generated image file can be examined
749using dumpe2fs and debugfs. In the future, e2fsck will be able to use
750the image file to help recover very badly damaged filesystems.
751
752Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
753no longer cause e2fsck to bomb out. Also treat files > 2GB as being
754large file when deciding whether or not the filesystem has large files.
755
756Fixed lsattr and chattr so that they work correctly on large files.
757(Fixes Debian bug #72690.)
758
759Removed limitation in get_device_size() which imposed a one terrabyte
760filesystem limitation. (Most 2.2 kernels still have a signed int
761problem which cause 1 TB block device limitation. Fortunately, the
762kernel patches to fix this are much easier than fixing the 2TB
763limitation in the kernel. :-)
764
765A max_mount_count of zero is now treated as if no mount count were
766set. (Previously, no mount count was indicated by using -1, and a
767mount count of zero caused e2fsck to always be run.)
768
Theodore Ts'o77648562001-05-14 13:04:44 +0000769Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000770
771Mke2fs now adds some randomness in s_max_mount_count so that multiple
772filesystems won't be all checked at the same time under normal
773operations.
774
Theodore Ts'o5570a652000-08-21 01:23:39 +0000775Fixed bug in the progress bar printing code which could cause e2fsck
776to core dump on an illegal filesystem.
777
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000778Fixed bug in fsck which could allow more than one instance of e2fsck
779to be printing a progress bar. (Debian bug #65267)
780
Theodore Ts'o5570a652000-08-21 01:23:39 +0000781Fsck using a UUID or a LABEL specifier will work even if devfs is
782compiled into the kernel and not mounted. If the pathnames in
783/proc/partitions are incorrect, fsck will search /dev for the correct
784device (using the new ext2fs_find_block_device library function).
785Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000786found when they are in use. Support has also been added to support
787additional IDE disks and the DAC 960 device names. (Debian bug #94159)
788
789Fixed a bug in fsck which caused it not deal properly with 16
790byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +0000791
Theodore Ts'o5a009bb2001-05-21 05:27:45 +0000792Fsck's -t option has been made a lot more flexible. The semantics for
793what happens if a comma-separated list to fsck has been regularized,
794and it is now possible to filter what filesystems will get checked
795based what is in the filesystem's fstab entry's option field. (Debian
796bug #89483.)
797
Theodore Ts'o5570a652000-08-21 01:23:39 +0000798The dumpe2fs program can now print out the group description
799information in hex, and also prints the location of the superblock and
800block group descriptor for those block groups that have them.
801
802Mke2fs now clears the ext2 superblock before it starts creating a
803filesystem, so that the superblock magic number is only written if the
804filesystem creation process successfully completes.
805
806The debugfs program's stat command now pretty-prints the blocks used
807by an inode so that it's more compact and informative.
808
809The debugfs stats command now uses the same libe2p code (which is used
810by dumpe2fs) to print the superblock header information. This is more
811complete, and it avoids a bit of code duplication.
812
813Added a new debugfs command, set_super_value (ssv) which allows the
814user to set arbitrary superblock fields.
815
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000816Debugfs was extended to support inode numbers in hex (by prefixing
817them with 0x), and so that modify_inode can set the inode generation
818number. Also, there is now a new function command called logdump
819which will dump an ext3 journal.
820
821Fixed a bug in debugfs so that quitting out of the pager doesn't kill
822debugfs.
823
824Debugfs's dump command now stops immediately upon reporting a disk
825read error. (Fixed a bug in ext2fs_file_read library routine which
826caused debugfs not to stop.) (Debian bug #79163)
827
828On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
829checked before /etc/mtab is used, since /proc/mounts is more likely to
830be accurate.
831
832Added portability fixes for Solaris and Linux/ia64.
833
834Various manual pages were clarified and cleaned up. (Fixed debian

838Programmer's notes:
839-------------------
840
841The e2fsck message printer now supports %Iu and %Ig, which will print
842out the inode's user and group owners, respectively.
843
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000844E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
845that no longer dependent on the system having the correct version of
846the kernel header files.
847
Theodore Ts'o5570a652000-08-21 01:23:39 +0000848Added a new function to libext2, ext2fs_find_block_device(), which
849searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
850device given its device number.
851
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000852Added a new function to libext2, ext2fs_sync_device, which centralizes
853all of the places which might try to use the BLKFLSBUF or FDFLUSH
854ioctls (and usually failing to define them since the system header
855files don't usually do this for us, and we're trying to avoid usage of
856kernel include files now).
857
Theodore Ts'o5570a652000-08-21 01:23:39 +0000858Added new utility programs in tests/progs: random_exercise and
859hold_inode. They aren't built by default; they're useful for
860exercising ext3 filesystem code.
861
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000862Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
863the filesystem close functions to only update the superblock, and to
864not touch the block group descriptors. Needed by tune2fs when
865modifying a mounted filesystem.
866
867Got rid of struct ext2fs_sb and replaced it with the standard struct
868ext2_super_block from include/linux/ext2_fs.h. Note: this may break
869source (but not binary) compatibility of some users of the ext2
870library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +0000871replace of struct ext2fs_sb with struct ext2_super_block, and include
872the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000873
874The ino_t type has been renamed ext2_ino_t to protect applications
875that attempt to compile -D_FILE_OFFSET_BITS=64, since this
876inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
877unexpected ABI change.
878
879The Makefiles have been reworked so that "make check" can be run from
880the top-level Makefile.
881
882Fix general gcc -Wall complaints and removed dead code.
883
884Remove use of NOARGS, because we assume everyone does ANSI C these
885days.
886
887Added build-rpm script from sct.
888
889New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
890to support e2image.
891
892New function ext2fs_flush_icache which must be called if the
893application program modifies the inode table blocks without going
894through ext2fs_write_inode() interface.
895
896New ext2fs_check_mount_point() function, which will return the mount
897point of a device if mounted.
898
899The io_channel abstraction now has an optional interface,
900io_channel_write_range, which allows specific byte ranges to be
901written.
902
903The unix_io IO channel now supports write-through caching, so that
904journal creation is more efficient.
905
906Added x86 assembly language routines to support byte swapping, to
907reduce executable size.
908
909Fixed bug in the utility program subst so that it's possible to
910replace a substitution variable with a zero-length string.
911
912Fixed numbering e2fsck pass1 problem numbers; an extra zero had
913slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +0000914
Theodore Ts'ob777e262000-07-27 01:39:23 +0000915E2fsprogs 1.19 (July 13, 2000)
916==============================
Theodore Ts'oab146762000-07-07 04:37:35 +0000917
918Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +0000919be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +0000920
921Add experimental support needed for the ext2 compression patches.
922This requires compiling e2fsprogs with the --enable-compression flag
923to the configure script.
924
925Added ext3 journalling support. E2fsck will run the journal (if
926necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
927installed as a symlink to e2fsck. Fsck has been taught about ext3,
928and treats it the same as ext2 in terms of the progress bar logic.
929Dumpe2fs will display the superblock journaling information if the
930filesystem has a journal. The ext2 library will now permit opening an
931ext3 filesystem with the recovery flag set. This is necessary for
932on-line dump's to work correctly, but there may be issues with this
933working well since ext3 is much less agressive about syncing blocks to
934the filesystem, since they're safe on the journal.
935
936Tune2fs and e2fsck have been changed to allow the mount_count check to
937be disabled by setting max_mount_count to -1. (This was already
938supported by the kernel.)
939
940Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
941are used for ext3 as well.
942
943Added internationalization support for e2fsprogs; must be enabled
944by passing --enable-nls to configure.
945
946Always use the provided ext2fs header files to insulate ourselves from
947kernel version changes. Which include files are used by e2fsprogs
948have also been cleaned up to improve portability.
949
950Limit the number of times that e2fsck updates the progress bar so that
951people who are booting using a 9600 baud console don't get swampped by
952too many updates.
953
954Improved the loop detection algorithm in e2sck's pass #3 so that it is
955much, much faster for large filesystems with a large number of
956directories.
957
958The memory footprint for e2fsck is now slightly smaller than before.
959
960E2fsck now checks if special devices have a non-zero size, and offers
961to clear the size field if it finds such an inode.
962
963E2fsck now checks if special devices have the append-only flag set,
964and offers to clear the inode.
965
966E2fsck now properly handles some "should never fail" cases during a
967bitmap copy in pass5.
968
969E2fsck now properly prints control characters in filenames as ^A .. ^Z.
970
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000971E2fsck now calculates the correct location of the backup superblock in
972the case of filesystem blocksizes > 1k.
973
974Fixed a bug in e2fsck's calculation of the number of inodes_per_block
975which normally didn't cause problems under most filesystem parameters,
976but could cause a valid superblock to be rejected in extreme cases.
977Other checks for validating superblock values were made more
978stringent.
979
Theodore Ts'oab146762000-07-07 04:37:35 +0000980Added non-destructive write testing to the badblocks program, courtesy
981of David Beattie. The badblocks also now has an option to input the
982current set of bad blocks, so that known bad blocks are skipped to
983speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +0000984feature which causes badblocks to run until it has completed some
985number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +0000986
987Badblocks now checks to see if the device is mounted and refuses to do
988the tests involving writing to the device if it is mounted. Also,
989badblocks now allows the number of blocks to be checked to be
990defaulted to the size of the partition.
991
992Fixed a bug in fsck which didn't allow non-root users to be able to
993check filesystems if there were any LABEL= or UUID= entries in
994/etc/fstab.
995
996The Hurd doesn't support the filetype filesystem feature. The mke2fs
997program now makes sure that for the Hurd, the filestype feature is
998turned off. E2fsck will check to see if the filetype feature is
999turned on for Hurd filesystems, and offer to turn off the feature.
1000
1001Mke2fs now has a safety check to make sure the number of blocks do not
1002exceed 32 bits even on a 64 bit platform.
1003
1004Really fixed a bug in fsck to allow "fsck -As" to run interactive
1005fsck's. (For those people who like to do interactive fsck's in the
1006/etc/rc scripts!?!)
1007
1008Debugfs has a few new features: the rdump command, which will do a
1009recursive dump of a directory and all of its contents, and the lcd
1010command which does a local chdir (much like the ftp command of the
1011same name). In addition, the debugfs program and the open_filesystem
1012command now takes three new options: -b and -s, which allows the
1013blocksize and superblock location to be specified, and the -c option
1014which is used in catastrophic situations where the block group
1015descriptors are corrupt. If the -c option is specified, debugfs will
1016skip trying to read in the block and inode bitmaps.
1017
1018Debufs's lsdel command was fixed to handle bad blocks in the inode
1019table.
1020
1021A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
10224 digit years.
1023
1024General improvements in error messages
1025
1026 - Mke2fs prints a sane error message if the partition size is zero
1027 (usually because the partition table wasn't reread by the
1028 kernel due to the partition being busy), instead of "invalid
1029 argument passed to ext2 library while initializing superblock".
1030
1031 - Fsck now prints more self-explanatory message if an invalid UUID=
1032 or LABEL= specification is passed to it.
1033
1034UUID library changed to use the LGPL.
1035
1036Fixed a bug in the UUID library where very rapid calls to the
1037time-based UUID generator could cause duplicate UUID's to be returned.
1038This was not a problem for e2fsprogs, but it could be a problem for
1039other users of the library.
1040
1041Make the UUID library more robust in the face of missing or an
1042improper /dev/urandom or /dev/random files.
1043
1044Added some random portability fixes for Solaris.
1045
1046Some minor man page updates.
1047
1048Fixed a memory leak in the ss library.
1049
1050
1051Programmer's notes:
1052-------------------
1053
1054We now try to use lseek64 and open64 from the LFS if possible.
1055
1056The 3rd parameter in e2p's print_flags is now a flags word, instead of
1057a boolean option.
1058
1059The mark and unmark bitmap functions now return the previous state of
1060the bit that was being changed, which is useful for some speed
1061optimizations.
1062
1063The following functions have been added to enhance the badblocks list
1064handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1065ext2fs_badblocks_equal.
1066
1067The ext2 header files now have the latest journalling fields to the
1068superblock.
1069
1070The ext2fs_mkdir function in libext2fs now properly backs out of error
1071conditions robustly.
1072
1073Cleaned up makefiles:
1074 - to cleanly compile with the -j flag.
1075 - so distclean removes all generated files.
1076 - so in case of an error while installing header files, the make aborts.
1077
1078Fix test_script so that it works correctly when compiling in the
1079source directory.
1080
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001081The random UUID generation routine has been made slightly better in
1082the case where /dev/random doesn't exist. (Use of randomly-based UUID
1083is still not recommended if /dev/random doesn't exist, however; it's
1084better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00001085
1086Clean up the build process so it's more friendly in case of missing
1087directories.
1088
1089The ext2fs header file can now be #include'd into C++ programs.
1090
1091The e2p.h header file is now installed.
1092
1093Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
1094
1095
1096
Theodore Ts'o24ded091999-11-10 15:56:16 +00001097E2fsprogs 1.18 (November 10, 1999)
1098==================================
1099
1100Fix a core dumping bug in e2fsck if an imagic inode is present or
1101(more rarely) if the filesystem is badly corrupted enough that e2fsck
1102has to restart pass 1 processing. E2fsck now closes the filesystem
1103before freeing a large number of its data structures, so in the case
1104of future memory faults, at least the fixed filesystem will be fully
1105written out.
1106
1107If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1108imagic inode, it will offer to clear the imagic flag.
1109
1110E2fsck will now offer to clear the immutable flag on special files
1111(device/socket/fifos) when running it in non-preen mode.
1112
1113E2fsck will now set the filetype when creating /lost+found, and when
1114connected orphaned inodes to /lost+found.
1115
1116Debugfs's ncheck and icheck commands now handles the case where there
1117are bad blocks in the inode table without bombing out.
1118
1119The badblocks list processing code has been made more efficiently for
1120appending a large number of (ordered) badblocks to the badblocks list.
1121
1122Some minor man page updates.
1123
1124Fsck now allows interactive e2fsck's when using fsck -As (not a common
1125mode, but some people like to do this in boot scripts for silly reasons).
1126
1127Programmer's notes:
1128-------------------
1129
1130The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1131with the problem code convention.
1132
1133The badblocks list regression test program has been updated to work
1134with previously made API name changes.
1135
1136The ext2fs_free() command now uses the new badblocks API to avoid
1137using the compatibility layer.
1138
1139Added new regression test cases; the run_e2fsck test script now
1140supports the ability for a test case to run a prepratory command
1141before running e2fsck.
1142
Theodore Ts'o28e11941999-10-26 18:17:20 +00001143E2fsprogs 1.17 (October 26, 1999)
1144=================================
1145
1146Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1147infinite loop.
1148
1149Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1150thus potentially causing problems if a binary UUID contained a NULL
1151character.
1152
1153E2fsck now uses stricter checks for directory entries in pass 2:
1154zero-length filenames are not allowed; neither are 8 byte long
1155directory entries.
1156
1157The debugfs "dirty" command now clears the filesystem valid bit.
1158(Previously this just set the dirty-as-in-needs-writing-out-to-disk
1159bit in the in-core superblock image. The new functionality is more
1160what the user expects, and is more useful.)
1161
1162Added a debugging hook to test parallel fsck; if the environment
1163variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1164will be checked in parallel when they normally would not be.
1165
1166Programmer's notes:
1167-------------------
1168
1169Fixed some #ifdef's for compilation under the Hurd OS.
1170
1171Fixed minor W2K compatibility problems.
1172
1173Fixed some miscellaneous GCC warnings.
1174
1175
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001176E2fsprogs 1.16 (October 22, 1999)
1177=================================
1178
1179Fixed a race condition bug in fsck; when printing a progress bar, if
1180checking multiple filesystems in parallel, it was possible for fsck to
1181send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
1182handler, which would cause it to terminate with a signal 10.
1183
1184E2fsck now properly handles filesystems that have the
1185INCOMPAT_FILETYPE feature turned on. It can be used to convert a
1186filesystem into using or not using FILETYPE feature.
1187
1188E2fsck now properly handles filesystems that have the IMAGIC feature
1189turned on (this is used on Linux AFS servers).
1190
1191The mke2fs program now creates filesystems that have the filetype and
1192sparse_superblock features enabled by default, unless it is run on a
1193pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
1194so there is now a new flag -O which allows the user to specify with
1195which features she would like to create the filesystem; "mke2fs -O
1196none" will create a filesystsem compatible with 2.0 kernels.
1197
1198The tune2fs program now has a -O option which allows the user to set
1199and reset "safe" filesystem features. Currently, the only ones which
1200allows to be modified are the filetype and sparse_superblock features.
1201Note setting or clearing either feature will require running e2fsck on
1202the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
1203requires that there is enough free space on the filesystem for the
1204extra superblocks which will be created by e2fsck.)
1205
1206Debugfs can now set and print filesystem features in the superblock
1207using the "features" command. Dumpe2fs will print out the complete
1208set of features when listing the superblock.
1209
1210Dumpe2fs has new options -f (force) and -h (header-only).
1211
1212Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
1213message to come up. This could happen when decrementing or
1214incrementing a link count could result in an overflow.
1215
1216Fixed a bug in e2fsck where the block count on the lost+found
1217directory would not be properly incremented when the directory was
1218expanded to the point where an indirect block needed to be allocated.
1219
1220E2fsck now makes some additional sanity checks on the superblock to
1221avoid crashing or giving a memory allocation error if some of the
1222values in the superblock are unresonable (but the superblock otherwise
1223looks valid).
1224
1225Fixed a bug in e2fsck where a very badly corrupted filesystem might
1226require two passes to completely fix the filesystem. This happened if
1227an inode claimed blocks that was part of the filesystem metadata
1228(typically, when garbage was written into an inode table or indirect
1229block, since this kind of filesystem corruption normally doesn't
1230happen otherwise).
1231
1232On the Alpha, glibc declares st_flags although it isn't actually used;
1233the configure script was improved to detect this case so that
1234e2fsprogs can avoid using the non-functional stat field.
1235
1236The manual pages were updated to use a more consistent formatting
1237style consistent with standard Unix man pages. Mke2fs's man page
1238added documentation for a few previously undocumented options.
1239
1240Fixed minor display bugs in tune2fs and mke2fs.
1241
1242Programmer's notes:
1243-------------------
1244
1245Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
1246
1247Added features to parse and print feature strings into the e2p library.
1248(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
1249
1250ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
1251whose directory entries contain proper filetype information if the
1252filesystem supports it.
1253
1254ext2fs_link() now uses the low 3 bits of its flags parameter to pass
1255the directory entry filetype information. This is used to set the
1256directory entry filetype information if the filesystem supports it.
1257
1258Fixed a bug in ext2fs_expand_dir() where the block count in a
1259directory's inode would not be properly incremented when the directory
1260was expanded to the point where an indirect block needed to be
1261allocated.
1262
1263
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001264E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001265==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001266
1267Add configuration checks so that e2fsprogs will compile cleanly on
1268Linux 2.3 kernels that have renamed i_version to i_generation.
1269
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001270E2fsck now prints a progress/completion bar (and not just a simple
1271spinner) if the -C0 option is requested or if it receives a SIGUSR1
1272signal. Fsck will automatically manage the (potentially muliple)
1273e2fsck processes to print completion bars if it is given a -C option,
1274with the right thing happening if multiple filesystems are being
1275checked in parallel.
1276
1277Mke2fs now has better automatic hueristics to determine the filesystem
1278parameters to be used for a particular filesystem. Added a new option
1279-T which allows the user to specify how the filesystem is to be used,
1280which helps mke2fs do a better job selecting the filesystem parameters.
1281
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001282Mke2fs now creates revision 1 filesystems by default, and with the
1283sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001284not understood by Linux 2.0 kernels, so they will only allow read-only
1285mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001286
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001287Fix bug where if /dev/null couldn't be opened (should never happen),
1288e2fsck would hang in a tight loop.
1289
1290Make e2fsck handle the case where /lost+found isn't a directory.
1291
1292E2fsck now uses mallinfo if it exists to get accurate statistics about
1293its memory usage.
1294
1295Fix bug in e2fsck where it wouldn't check to see if a disconnected
1296inode had any problems before connecting it to /lost+found.
1297
1298Add check to e2fsck so it makes sure that total number of inodes in
1299the filesystem is a sane number.
1300
1301Fix fencepost error when clearing an the end of the block bitmap which
1302caused the last block in the bitmap not to get cleared.
1303
1304Cleaned up a number of messages in e2fsck:
1305 * The message "Group's #'s copy of the group descriptor..."
1306 was fixed so that the correct number would be displayed.
1307 * Added missing space in the "disk write-protected" error messsage
1308 * Cleaned up the error message printed when a non-interactive
1309 e2fsck needs to abort a check because the filesystem
1310 appears to be mounted.
1311
1312Added a new command-line utility, uuidgen, which will create and print
1313a UUID.
1314
1315Make debugfs's icheck command more robust by checking to make sure an
1316inode has valid blocks before interarting over the inode's blocks.
1317
1318UUID generation now uses a random-based scheme whenever possible to
1319prevent potential privacy problems.
1320
1321Man pages for all of the UUID functions in the lirbary were added.
1322
1323Fixed bug in fsck so it won't coredump if a filesystem not in
1324/etc/fstab is given to it.
1325
1326Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
1327that most of the other mount utilities understands.
1328
1329Mke2fs will make a filesystem even if it appears mounted if the force
1330option is given.
1331
1332Dumpe2fs has new command-line options which allow a filesystem expert
1333to specify the superblock and blocksize when opening a filesystem.
1334This is mainly useful when examining the remains of a toasted
1335filesystem.
1336
1337The badblocks program has been updated to display correctly on disks
1338with large block numbers.
1339
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001340The badblocks program no longer gives spurious errors when errors
1341occur on non-block boundaries, which is common if the blocksize is
1342larger than 1k.
1343
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001344Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
1345MKE2FS_SYNC environment variable is set. This is to work around a VM
1346bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001347to trigger it even using a 2.2 kernel, but hopefully it will not be
1348needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001349
1350Fixed miscellaneous documentation and man pages.
1351
1352Programmer's notes:
1353-------------------
1354
1355Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
1356in e2fsck's pass1.c really should have been static.
1357
1358The return value of the uuid_compare() function was changed to make it
1359match with the convetions used by strcmp, memcmp, and Paul Leach's
1360UUID sample document.
1361
1362The "make depend" process has now been made more automated; it now
1363automatically word-wraps the dependencies, and only replaces source
1364Makefile.in if there has been a change in the dependencies. Also, a
1365top-level "make depend" now recurses through all the subdirectories
1366automatically.
1367
1368The Makefile in .../util has been changed so that subst is built using
1369the native C compiler during a cross-compilation, since the subst
1370program is only used during the build process. Also add an explicit
1371rule to build util/subst by cd'ing to the correct directory and
1372running Makefile.
1373
1374The man directories are defined in terms mandir, so that the configure
1375script can override the location of the manual pages.
1376
1377The config files have been updated to recognize new machine types for
1378both the i386 and alpha families.
1379
1380Fsck has been modified so that it will accurately create an
1381fsck_instance even when the noexecute flag is set. This allows for
1382accurate debugging of the fsck pass structure. Also, when the verbose
1383flag is given twice, fsck will print debugging information about when
1384fsck is waiting for jobs to finish.
1385
1386
Theodore Ts'o14790ed1999-01-12 23:32:52 +00001387E2fsprogs 1.14 (January 9, 1999)
1388================================
1389
1390Fix the fstab parsing code so that it can handle blank lines and
1391comment characters. Also, missing pass numbers need to be treated as
1392zero.
1393
1394Fixed a bug in e2fsck where under some circumstances (when e2fsck
1395needs to restart processing after fixing an egregious inconsistency)
1396it would try to access already freed memory.
1397
1398E2fsck now prints non-printable characters in directory entries and
1399pathnames using '^' and 'M-' notation.
1400
1401Fixed chattr so that it will ignore symbolic links when doing
1402recursive descent traversals. For both chattr and lsattr, no longer
1403print the version string unless the -V option is given.
1404
1405Allow the system administrator to directly specify the number of
1406inodes desired in the filesystem, for some special cases where this is
1407necessary.
1408
1409Fix portability problems so that e2fsprogs can be compiled under Linux
14101.2 systems and Solaris systems.
1411
1412Update the config.guess file with a more recent version that will
1413identify newer Linux platforms.
1414
1415Programmer's notes
1416------------------
1417
1418Ext2fs_read_inode and ext2fs_write_inode will now return an error if
1419an inode number of zero is passed to them.
1420
Theodore Ts'o556ad131998-12-19 08:10:58 +00001421E2fsprogs 1.13 (December 15, 1998)
1422==================================
1423
1424Fixed a bug in debugfs where an error messages weren't getting printed
1425when the ext2 library routines to read inodes returned errors in the
1426stat, cmri and rm commands.
1427
1428Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
1429provided, it won't create an inode table smaller than the minimum
1430number of inodes required for a proper ext2 filesystem.
1431
1432Fsck now parses the /etc/fstab file directly (instead of using
1433getmntent()), so that it can distinguish between a missing pass number
1434field and pass number field of zero. This caused problems for
1435diskless workstations where all of the filesystems in /etc/fstab have
1436an explicit pass number of zero, and fsck could not distinguish this
1437from a /etc/fstab file with missing pass numbers.
1438
1439E2fsck will create a /lost+found directory if there isn't one in the
1440filesystem, since it's safer to create the lost+found directory before
1441it's needed.
1442
1443Fixed e2fsck so that it would detect bogus immutable inodes which
1444happen to be sockets and FIFO files, and offer to clear them.
1445
1446If a filesystem has multiple reasons why it needs to be checked, and
1447one of the reasons is that it is uncleanly mounted, e2fsck will print
1448that as the reason why the filesystem is being checked.
1449
1450Cleaned up the output routines of mke2fs so that it doesn't overflow
1451an 80 column display when formating really big filesystems.
1452
1453Added a sanity check to e2fsck to make sure that file descriptors 0,
14541, 2 are open before opening the hard disk. This avoids a problem
1455where a broken program might exec e2fsck with those file descriptors
1456closed, which would cause disastrous results if the kernel returns a
1457file descriptor for the block device which is also used by FILE *
1458stdout.
1459
1460Fixed up the e2fsck progress reporting functions so that the values
1461reliably reach 100% at the completion of all of the e2fsck passes.
1462
1463Fixed minor documentation bugs in man pages and usage messages.
1464
1465Programmer's notes:
1466-------------------
1467
1468Fixed a number of lint warnings in the ext2fs library and potential
1469portability problems from other OS's header files that might define
1470CPP macros for names like "max" and "min".
1471
1472ext2fs_badblocks_list_add() has been made more efficient when it needs
1473to grow the bad blocks list.
1474
1475Fixed a bug in e2fsck which caused it to dereference a freed pointer
1476just before exiting.
1477
1478Fixed the substition process for generating the mk_cmds and compile_et
1479scripts so that they will work outside of the build tree.
1480
1481Add sanity check to e2fsck so that if an internal routine
1482(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
1483and causing a core dump. This should never happen, but...
1484
Theodore Ts'oa5696711998-07-09 05:38:07 +00001485E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00001486==================================
1487
1488E2fsprogs now works with glibc (at least with the version shipped wtih
1489RedHat 5.0). The ext2fs_llseek() function should now work even with
1490i386 ELF shared libraries and if llseek() is not present. We also
1491explicitly do a configure test to see if (a) llseek is in libc, and
1492(b) if llseek is declared in the system header files. (See standard
1493complaints about libc developers don't understand the concept of
1494compatibility with previous versions of libc.)
1495
Theodore Ts'oc9833a61998-07-05 19:37:53 +00001496The ext2fs library now writes out the block group number in each of
1497the superblock copies. This makes it easier to automatically
1498determine the starting block group of the filesystem when the block
1499group information is trashed.
1500
1501Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00001502which means that e2fsprogs will ignore the high 8 bits of the
1503directory entry's name_len field, so that it can be used for other
1504purposes.
1505
1506Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
1507E2fsprogs will now support filesystems with 64-bit sized files.
1508
1509Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
1510
Theodore Ts'o21d53851998-02-21 03:14:50 +00001511Added new program "e2label", contributed by Andries Brouwer. E2label
1512provides an easy-to-use interface to modify the filesystem label.
1513
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00001514Fixed bug so that lsattr -v works instead of producing a core dump.
1515
Theodore Ts'o21d53851998-02-21 03:14:50 +00001516Fixed a minor bug in mke2fs so that all groups with bad superblock
1517backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00001518
1519Mke2fs will check the size of the device, and if the user specifies a
1520filesystem size larger than the apparent size of the device it will
1521print a warning message and ask if the user wants to proceed.
1522
Theodore Ts'oc9833a61998-07-05 19:37:53 +00001523E2fsck has a new option -C, which sends completion information to the
1524specified file descriptor. For the most part, this is intended for
1525programs to use, although -C 0 will print a spinning character to the
1526stdout device, which may be useful for users who want to see something
1527happening while e2fsck goes about its business.
1528
Theodore Ts'o21d53851998-02-21 03:14:50 +00001529Fixed a bug in e2fsck which could cause a core dump when it needs to
1530expand the /lost+found directory, and sometimes the bitmaps haven't
1531been merged in. Also fixed a related bug where ext2fs_write_dir_block
1532was used to write out a non-directory block. (Which would be bad on a
1533non-Intel platform with byte swapping going on.)
1534
1535Fixed bug in e2fsck where it would print a "programming error" message
1536instead of correctly identifying where a bad block was in used when
1537the bad block was in a non-primary superblock or block group
1538descriptor. Also fixed a related bug when sparse superblocks are in
1539use and there is a bad block where a superblock or block group
1540descriptor would have been in a group that doesn't include a
1541superblock.
1542
1543Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
1544the block group descriptor table is corrupt, it was possible to try to
1545allocate a huge array, fail, and then abort e2fsck.
1546ext2fs_get_num_dirs() now sanity checks the block group descriptor,
1547and subsitutes reasonable values if the descriptors are obviously bogus.
1548
1549If e2fsck finds a device file which has the immutable flag set and the
1550i_blocks beyond the normal device number are non-zero, e2fsck will
1551offer to remove it, since it's probably caused by garbage in the inode
1552table.
1553
1554When opening a filesystem, e2fsck specially checks for the EROFS error
1555code, and prints a specific error message to the user which is more
1556user friendly.
1557
1558If the filesystem revision is too high, change the e2fsck to print
1559that this is either because e2fsck is out of date, or because the
1560superblock is corrupt.
1561
1562E2fsck now checks for directories that have duplicate '.' and '..'
1563entries, and fixes this corruption.
1564
1565E2fsck no longer forces a sync of the filesystem (with attendant sleep
1566calls) at all times. The ext2fs_flush() function now performs a sync
1567only if it needed to write data blocks to disk.
1568
1569Fixed a minor bug in e2fsck's pass1b's file cloning function, where
1570certain errors would not be properly reported.
1571
1572Updated and expanded a few points in the man pages which users
1573complained wheren't explicit enough.
1574
1575Added special case byte-swapping code if compiling on the PowerPC, to
1576accomodate the strange big-endian variant of the ext2 filesystem that
1577was previously used on the PowerPC port.
1578
1579
1580Programmer's notes:
1581-------------------
1582
1583Removed C++ keywords from the ext2fs libraries so that it could be
1584compiled with C++.
1585
1586E2fsck's internal organization has now been massively reorganized so
1587that pass*.c don't have any printf statements. Instead, all problems
1588are reported through the fix_problem() abstraction interface. E2fsck
1589has also been revamped so that it can be called as a library from a
1590application.
1591
1592Added new fileio primitives in libext2fs for reading and writing
1593files on an unmounted ext2 filesystem. This interface is now used by
1594debugfs.
1595
1596Added a new libext2fs function for mapping logical block numbers of
1597a file to a physical block number.
1598
1599Added a new libext2fs function, ext2fs_alloc_block(), which allocates
1600a block, zeros it, and updates the filesystem accounting records
1601appropriately.
1602
1603Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
1604sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
1605
1606The libext2fs functions now use a set of memory allocation wrapper
1607functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
1608instead of malloc, free, and resize. This makes it easier for us to
1609be ported to strange environments where malloc, et. al. aren't
1610necessarily available.
1611
1612Change the libext2fs fucntion to return ext2-specific error codes
1613(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
1614and depending on the existence of system error codes (such as EEXIST
1615and ENOENT).
1616
1617Renamed io.h to ext2_io.h to avoid collision with other OS's header
1618files.
1619
1620Add protection against ext2_io.h and ext2fs.h being included multiple
1621times.
1622
1623The types used for memory lengths, etc. have been made more portable.
1624In generla, the code has been made 16-bit safe. Added Mark
1625Habersack's contributed DOS disk i/o routines.
1626
1627Miscellaneous portability fixes, including not depending on char's
1628being signed.
1629
1630The io_channel structure has a new element, app_data, which is
1631initialized by the ext2fs routines to contain a copy of the filesystem
1632handle.
1633
1634ext2fs_check_directory()'s callback function may now return the error
1635EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
1636really do the checking, despite the presence of the callback function.
1637
1638
Theodore Ts'obc210071997-06-17 05:41:36 +00001639E2fsprosg 1.11 (June 17, 1997)
1640==============================
1641
1642Fixed e2fsck to detect (previously ignored) conflicts between the
1643superblock or block group descriptors and block bitmaps, inode
1644bitmaps, and inode tables.
1645
1646Fixed bug in e2fsck so that when the message printed out when a block
1647or inode bitmap conflicts with other data, it has the correct group
1648number.
1649
1650Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
1651to badblocks. This meant that not all of the filesystem was being
1652tested for bad blocks!
1653
1654Fixed an array boundary overrun case which cropped up in
1655ext2fs_badblocks_list_test when a user tried running "mke2fs -c
1656-b 4096".
1657
1658Adjusted the number of columns printed by mke2fs when displaying the
1659superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00001660really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00001661
1662Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
1663dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
1664fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
1665
1666Programmer's notes:
1667-------------------
1668
1669Fixed install rule in lib/ss so that ss_err.h is actually getting
1670installed.
1671
1672Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
1673bassed back to the caller.
1674
1675Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
1676setting the current inode number (which meant this function wasn't
1677working at all).
1678
1679Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
1680blocks in the bitmap when increasing the size of the bitmap.
1681
1682Changed the initial number of blocks allocated by ext2fs_init_dblist()
1683to be more realistic.
1684
1685Added a new function ext2fs_allocate_group_table, which sets up the
1686group descriptor information (and allocates inode and block bitmaps,
1687and inode tables for a particular group). The function was created by
1688factoring out code form ext2fs_allocate_tables().
1689
1690Added a new function ext2fs_move_blocks which takes a bitmap of the
1691blocks to be moved, and moves them to another location on the
1692boardboard.
1693
1694Make the unix_io channel's io_channel_flush implementation calls sync()
1695to to flush the kernel buffers to disk.
1696
1697Added a new function ext2fs_dblist_count returns the number of
1698directory blocks in dblist.
1699

Theodore Ts'oae851481997-04-29 18:13:24 +00001701E2fsprogs 1.10 (April 24, 1997)
1702===============================
1703
1704Mke2fs once again defaults to creating revision #0 filesystems, since
1705people were complaining about breaking compatibility with 1.2 kernels.
1706Warning messages were added to the mke2fs and tune2fs man pages that
1707the sparse superblock option isn't supported by most kernels yet (1.2
1708and 2.0 both don't support parse superblocks.)
1709
1710Added new flag to mke2fs, -R <raid options>, which allows the user to
1711tell mke2fs about the RAID configuration of the filesystem. Currently
1712the only supported raid option is "stride" which specifies the width
1713of the RAID stripe.
1714
1715Fixed bug in e2fsck where pass1b would bomb out if there were any
1716blocks marked bad in the inode table.
1717
1718Fixed rare bug in mke2fs where if the user had a very unlucky number
1719of blocks in a filesystem (probability less than .002) the resulting
1720filesystem would be corrupt in the last block group.
1721
1722Fixed bug where if e2fsck tried to allocate a block to fix a
1723filesystem corruption problem and the filesystem had no free blocks,
1724ext2fs_new_block() would loop forever.
1725
1726The configure script now checks explicitly to see if "-static" works,
1727since that can't be assumed to be true --- RedHat doesn't install
1728libc-static by default.
1729
1730Fixed bug in libext2's block iterator functions where under some
1731cirmcustances, file with holes would cause the bcount parameter to the
1732callback function to be incorrect. This bug didn't affect any of
1733e2fsprogs programs, but it was discovered by Paul Mackerras, the
1734author of the PPC boot loader.
1735
1736Removed use of static variables to store the inode cache in libext2fs.
1737This caused problems if more than one filesystem was accessed via
1738libext2fs (static variables in libraries are generally a bad idea).
1739Again, this didn't affect e2fsprogs programs, but it was discovered by
1740Paul Mackerras.
1741
1742Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
1743will compile cleanly with 1.2.13 kernels (even with a.out shared
1744libraries!)
1745
1746Programmer's notes:
1747-------------------
1748
1749Added new functions to duplicate an ext2 filesystem handle, and its
1750associated substructure. New functions: ext2fs_dup_handle(),
1751ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
1752Other structures, such as the io_channel and the inode_cache, now have
1753a ref count so that they only get freed when they are no longer used
1754by any filesystem handle. (These functions were added as part of the
1755development effort for an ext2 resizer).

Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00001757E2fsprogs 1.09 (April 14, 1997)
1758===============================
1759
1760Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
1761accidentally introduced in the 1.08 release. The overhead calculation
1762was accidentally removed, which caused ext2fs_initialize() to not
1763notice when the filesystem size needed to be adjusted down because
1764there wasn't enough space in the last block group.
1765
1766Fixed bug in version parsing library routine; it was always parsing
1767the library version string, instead of using the passed-in string.
1768
1769Clarified chattr man page.
1770
Theodore Ts'o24757fa1997-04-29 17:39:27 +00001771E2fsprogs 1.08 (April 10, 1997)
1772===============================
1773
1774E2fsck 1.07 was very slow when checking very large filesystems with a
1775lot of files that had hard links (i.e., news spools). This was fixed
1776by seriously revamping the icount abstraction. Added a formal test
1777suite for the icount abstraction.
1778
1779Debugfs now has a "-l" option to the "ls" command, which lists the
1780inode number, permissions, owner, group, size, and name of the files
1781in the directory.
1782
1783Fix a bug in e2fsck where when a directory had its blocks moved to
1784another location during the pass 1b processing, the directory block
1785list wasn't updated, so pass 2 wouldn't check (and correct) the
1786correct directory block.
1787
1788E2fsck will now treat inodes which contain blocks which are claimed by
1789the filesystem metadata by treating them as multiply claimed blocks.
1790This way, the data in those blocks can be copied to a new block during
1791the pass 1b--1d processing.
1792
1793E2fsck will attempt to determine the correct superblock number and
1794display it in the diagnostic and warning messages if possible.
1795
1796Add support for a new (incompatible) feature, "sparse_super". This
1797feature reduces the number of blocks which contain copies of backup
1798superblocks and block group descriptors. (It is only an incompatible
1799feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
1800support a new -s option; e2fsck will recognize filesystems built with
1801this feature turned on.
1802
1803E2fsck now checks the library to make sure is the correct version,
1804using new library functions. (This helps to diagnose incorrectly
1805installed e2fsprogs distributions.)
1806
1807Dumpe2fs now prints more information; its now prints the the
1808filesystem revision number, the filesystem sparse_super feature (if
1809present), the block ranges for each block group, and the offset from
1810the beginning of the block group.
1811
1812Mke2fs now distributes the inode and block bitmap blok so that the
1813won't be concentrated in one or two disks in RAID/striping setups.
1814Also, if the user chooses a 2k or 4k block group, mke2fs will try to
1815choose the largest blocks per group that be chosen. (For 2k blocks,
1816you can have up to 16384 blocks/group; for 4k blocks, you can have up
1817to 32768 blocks/group.) Previously mke2fs would not allow
1818specification of more than 8192 blocks per group, even if you were
1819using a 2k or 4k block group.
1820
1821Programmer's notes:
1822-------------------
1823
1824Added a new function ext2fs_create_icount2() which takes a "hint"
1825argument. This hint argument presets the icount array with the list
1826of inodes which actually need to be in the icount array. This really
1827helps to speed up e2fsck.
1828
1829Added a new function ext2fs_icount_validate() which checks the rep
1830invariant for the icount structure. This is used mostly for testing.
1831
1832The error mesasage given when a bad inode number is passed to
1833test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
1834EXT2FS_UNMARK_ERROR).
1835
1836Added a new function ext2fs_set_dir_block which sets the block of a
1837dblist entry, given the directory inode and blockcnt.
1838
1839Added a new function ext2fs_get_library_version() which returns the
1840current library version, and ext2fs_parse_version_string() which
1841returns a version number based on a e2fsprogs version string.
1842
1843The icount functions will return EINVAL if the passed in inode number
1844is out of bounds.
1845
Theodore Ts'o21c84b71997-04-29 16:15:03 +00001846E2fsprogs 1.07 (March 9, 1997)
1847==============================
1848
1849E2fsck is now uses much less memory when checking really large
1850filesystems (or rather, filesystems with a large number of inodes).
1851Previously a filesystem with 1 million inodes required 4 megabytes of
1852memory to store inode count statistics; that storage requirement has
1853now been reduced to roughly half a megabyte.
1854
1855E2fsck can now properly deal with bad blocks appearing inside the
1856inode table. Instead of trying to relocate the inode table (which
1857often failed because there wasn't enough space), the inodes in the bad
1858block are marked as in use.
1859
1860E2fsck will automatically try to use the backup superblocks if the
1861primary superblocks have a bad magic number or have missing meta-data
1862blocks (or meta-data blocks which are out of range).
1863
1864E2fsck's pass 3 has been made more efficient; most noticeable on
1865filesystems with a very large number of directories.
1866
1867Completely revamped e2fsck's system of printing problem reports. It
1868is now table driven, to make them more easily customizeable and
1869extendable. Error messages which can be printed out during preen mode
1870are now one line long.
1871
1872Fixed e2fsck's filesystem swapping code so that it won't try to swap
1873fast symbolic links or deleted files.
1874
1875Fixed e2fsck core dumping when fixing a filesystem which has no
1876directories (not even a root directory).
1877
1878Added a check to e2fsck to make sure that the length of every
1879directory entry is a multiple of 4 (since the kernel complains if it
1880isn't).
1881
1882Added a check to e2fsck to make sure that a directory entry isn't a
1883link to the root directory, since that isn't allowed.
1884
1885Added a check to e2fsk to now make sure the '.' and '..' directory
1886entries are null terminated, since the 2.0 kernel requires it.
1887
1888Added check to write_bitmaps() to make sure the superblock doesn't get
1889trashed if the inode or block bitmap is marked as being block zero.
1890
1891Added checking of the new feature set fields in the superblock, to
1892avoid dealing with new filesystem features that this package wasn't
1893set up to handle.
1894
1895Fixed a fencepost error in ext2fs_new_block() which would occasionally
1896try to allocate a block beyond the end of a filesystem.
1897
1898When the UUID library picks a random IEEE 802 address (because it
1899can't find one from a network card), it sets the multicast bit, to
1900avoid conflicting with a legitimate IEEE 802 address.
1901
1902Mke2fs now sets the root directory's owner to be the real uid of the
1903user running mke2fs. If the real uid is non-zero, it also sets
1904the group ownership of the root directory to be the real group-id of
1905the user running mke2fs.
1906
1907Mke2fs now has more intelligent error checking when it is given a
1908non-existent device.
1909
1910When badblocks is given the -vv option, it now updates the block that
1911it is currently testing on every block.
1912
1913Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
1914currently correctly if PATH wasn't already set.
1915
1916Shared libraries now built with dependencies. This allows the shared
1917library files to be used with dlopen(); it also makes the transition
1918to libc 6 easier, since ld.so can tell which libc a particular shared
1919library expects to use.
1920
1921Programmer's notes:
1922-------------------
1923
1924Added new abstraction (defined in dblist.c) for maintaining a list of
1925blocks which belongs to directories. This is used in e2fsck and other
1926programs which need to iterate over all directories.
1927
1928Added new functions which test to see if a contiguous range of blocks
1929(or inodes) are available. (ext2fs_*_bitmap_range).
1930
1931Added new function (ext2_inode_has_valid_blocks) which returns true if
1932an inode has valid blocks. (moved from e2fsck code).
1933
1934Added new function (ext2fs_allocate_tables) which allocates the
1935meta-data blocks as part of initializing a filesystem. (moved from
1936mke2fs code).
1937
1938Added a new I/O manager for testing purposes. It will either allow a
1939program to intercept I/O requests, or print debugging messages to
1940trace the activity of a program using the I/O manager.
1941
1942The badblocks_list functions now store the bad blocks in a sorted
1943order, and use a binary search to speed up badblocks_list_test.
1944
1945The inode scan function ext2fs_get_next_inode() may now return a soft
1946error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
1947those cases where part of an inode table is missing or there is a bad
1948block in the inode table.
1949
1950Added a new function (ext2fs_block_iterate2) which adds new arguments to
1951the callback function to return a pointer (block and offset) to the
1952reference of the block.
1953
1954Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
1955application to jump to a particular block group while doing an inode
1956scan.
1957
1958The badblocks list functions were renamed from badblocks_* to
1959ext2fs_badblocks_*. Backwards compatibility functions are available
1960for now, but programs should be modified to use the new interface.
1961
1962Some of the library functions were reorganized into separate files to
1963reduce the size of some programs which statically link against the
1964ext2 library.
1965
1966Put in some miscellaneous fixes for the Alpha platform.
1967

1969E2fsprogs 1.06 (October 7, 1996)
1970================================
1971
1972Fixed serious bug in e2fsck: if the block descriptors are bad, don't
1973smash the backup copies in ext2fs_close(). (The problem was that when
1974e2fsck -p discovered the problem, while it was closing the filesystem
1975and exiting, it was also blowing away the backup superblocks on the
1976disk, which was less than friendly.) We now make it the case that we
1977only write out the backup superblock and the back block descriptors if
1978the filesystem is completely free from problems.
1979
1980Fixed a bug in block_interate in the lib/ext2fs library which caused
1981e2fsck to fail on GNU Hurd-created filesystems.
1982
1983Add support for Linux/FT's bootloader, which actually uses
1984EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
1985to clear the inode.
1986
1987Add support for the "A" (no atime update) attribute. (Note: this
1988attribute is not yet in production kernels.)
1989
1990The test suite is not automatically run when doing a "make all" from
1991the top level directory. Users should manually run "make check" if
1992they wish to run the test suite.
1993
1994Upon a preenhalt(), make the printed message more explicit that
1995running e2fsck "MANAULLY" means without the -p or -a options.
1996
1997In e2fsck, if a disconnected inode is zero-length, offer to clear it
1998instead of offering to connect it to lost+found.
1999
2000In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2001e2fsck to be run over it, change e2fsck to explicitly display this
2002fact.
2003
2004For dumpe2fs and e2fsck, cause the -V option to print out which
2005version of the ext2fs library is actually getting used. (This will
2006help detect mismatches of using a 1.06 utility with a 1.05 library,
2007etc.)
2008
2009Programmers' notes:
2010-------------------
2011
2012EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2013the naming convention.
2014
2015In ext2fs_initialize(), make sure the description for the inode bitmap
2016is correctly initialize.
2017
2018Fixed minor type typo in ext2fs_allocate_generic_bitmap();
2019
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002020E2fsprogs 1.05 (September 7, 1996)
2021==================================
2022
2023Add support for new fields in the ext2 superblock --- volume name,
2024volume UUID, and last mounted field. Dumpe2fs displays these fields,
2025tune2fs and mke2fs allows you to set them. E2fsck will automatically
2026generate a UUID for those volumes that don't have them.
2027
2028Put in support for e2fsck to recognize HURD specific ext2 features ---
2029most notably, the translator block. The e2fsprogs tools will now use
2030the creator_os field in the superblock to correctly handle different
2031OS-specific variants of the ext2 filesystem.
2032
2033E2fsck now fixes inodes which have a the deletion time set, but which
2034have a non-zero i_link_count field by offering to clear the deletion
2035time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2036ext2 kernel behavior) and offered to unlink the file.
2037
2038If e2fsck sets the clean bit, but nothing else, set the exit code
2039FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2040set the filesystem valid bit when it was previously cleared. :-) This
2041was needed to make the HURD fsck driver happy.
2042
2043If the user refuses to attach an unattached inode, e2fsck will no
2044longer set the inode's link count. Otherwise, the inode would end up
2045getting marked as unused, which might cause loss of data later.
2046
2047Make the message issued by e2fsck when the superblock is corrupt less
2048confusing for users. It now mentions that another reason for the
2049"corrupt superblock" message might be that the partition might not be
2050an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2051
2052Make the libext2 library more robuest so that e2fsck won't coredump on
2053an illegal superblock where the blocksize is zero. (f_crashdisk is
2054the test case).
2055
2056By default, create filesystems where the default checkinterval is 6
2057months (180 days). Linux servers can be robust enough that 20 reboots
2058can be a long, long time.
2059
2060Added configure flag --enable-old-bitops, which forces the bitops to
2061use the old (native) bitmask operations. By default on the sparc
2062platform, the standard ext2 bit ordering is now used.
2063
2064Added a new feature to e2fsck to byte-swap filesystems; this can be
2065used to convert old m68k filesystems to use the standard byte-order
2066storage for the superblock, inodes, and directory blocks. This
2067function is invoked by using the '-s' option to e2fsck.
2068
2069Debugfs's "dump" command has been enhanced so that it writes out the
2070exact size of the file so that the nulls at the end of the file are
2071eliminated. The command also accept a new "-p" option which will
2072attempt preserve to preserve the ownernship, permissions, and
2073file modification/access times.
2074
2075Debugfs has two new options, -f and -R. The -R option allows the user
2076to execute a single debugfs command from the command line. The -f
2077option allows the user to specify a "command file" containing debugfs
2078commands which will get executed.
2079
2080Dumpe2fs now pretty prints the check interval, instead of just
2081printing the check interval as a number of seconds.
2082
2083Fix bugs in debugfs: the params command when no filesystem is opened
2084no longer causes a core dump. It is now possible to unlink a file
2085when a pathame containing a '/' is specified.
2086
2087Tune2fs has a new -C option which sets the number of times the
2088filesystem has been mounted.
2089
2090Fix the chattr '-v' option so that it actually works. Chattr was
2091being buggy about the -v option parsing.
2092
2093Programmers' notes:
2094-------------------
2095
2096The directory lib/uuid contains a set of library routines to generate
2097DCE compatible UUIDs.
2098
2099Extended ext2fs_namei() to handle symbolic links. Added new function
2100ext2fs_nami_follow() which will follow last symbolic link in the case
2101where the pathname points to a sym link.
2102
2103The ext2fs_block_iterate function will now return the HURD translator
2104block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2105iterator to return data blocks only. The ext2fs.h file now defines
2106constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2107BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2108count field of the iterator callback function.
2109
2110The test script driver now takes an optional second argument, which is
2111the test case to be run. This allows you to run a test case without
2112needing to run the entire test suite.
2113
2114On Linux ELF systems, install the .so files in the correct places
2115(/usr/lib). The .so files must be stored in the same directory as the
2116.a files.
2117
2118Fixed miscellaneous HURD compilation issues with header file being
2119included in the right order.
2120
2121Fixed debugfs so that it resets optind to zero, not one, since setting
2122optind to zero is more correct.
2123
2124
Theodore Ts'oa4d09611997-04-29 14:28:00 +00002125E2fsprogs 1.04 (May 16, 1996)
2126=============================
2127
2128First "official" (1.03 was a limited release only) to support building
2129e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2130kernels).
2131
2132This package includes a RPM specs file, that it can be built using the
2133RedHat Package Manager.
2134
2135E2fsck now prints a hint that if there are lots of incorrectly located
2136inode bitmaps, block bitmaps, and inode table blocks, the user might
2137want to try using e2fsck -b 8193 first, to see if that fares any
2138better.
2139
2140For ext2 filesystem written with the hurd, debugfs will now print out
2141the translator field when printing an inode structure.
2142
2143Lots of miscellaneous linking/installation cleanups:
2144
2145 Libraries are now linked using a relative pathname, instead of
2146 relying on -L working correct. It doesn't, in many cases, including
2147 current versions of GNU ld. This guarantees that the build tree is
2148 linking with the right libraries, instead of the ones installed in
2149 /usr/lib.
2150
2151 Header files, man pages, and the et/ss shell scripts are now
2152 generated using a custom substitution script, instead of relying on
2153 the configure script. This prevents needless recompilation of
2154 files; in addition, the custom substitution script is much faster.
2155
2156 e2fsck may now be linked dynamically, by using the
2157 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2158 since it increases e2fsck's dependence on other files, but some
2159 people need to save disk space, and other critical programs on their
2160 systems were being linked dynamically anyway.
2161
2162 Programs such as fsck which didn't need to be linked against
2163 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2164 only link against libraries they actually need. Otherwise, those
2165 programs would require the presense of libraries that otherwise
2166 could be removed from a rescuse diskette.
2167
2168 The ss include files are now installed correctly so they can
2169 actually be used by another package.
2170
2171 If the profiling libraries are built, they are now installed on a
2172 "make install-libs".
2173
2174
Theodore Ts'o7f88b041997-04-26 14:48:50 +00002175E2fsprogs 1.03 (March 27, 1996)
2176===============================
2177
2178Change the m68k bit numbering for bitmasks to match the bit numbering
2179used by all other ext2 implementations. (This change was requested by
2180the m68k kernel development team.)
2181
2182Support (in-development) filesystem format revision which supports
2183(among other things) dynamically sized inodes.
2184
2185Fixed a bug in the ext2 library so that an intelligent error is
2186returned if mke2fs is run with a ridiculously small number of blocks
2187for a partition.
2188
2189Fixed a bug in the ext2 library which required that the device be
2190openable in read/write mode in order to determine its size. This
2191caused e2fsck -n to require read/write access when it was not
2192previously necessary.
2193
2194Fixed a bug in e2fsck which casued it to occasionally fail the test
2195suite depending on which version of the floating point library it was
2196using.
2197
2198Fixed a bug in e2fsck so that it now halts with a fatal error when
2199certain superblock consistency checks fail. Previously it continued
2200running e2fsck, with some potential confusing/damaging consequences.
2201
2202Added new flag to fsck which allows the root to be checked in parallel
2203with other filesytems. This is not the safest thing in the world to

2209E2fsprogs 1.02 (January 16, 1996)
2210=================================
2211
2212Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
2213
2214Change e2fsck to print statistics of how many non-contiguous files are
2215on the system. Note that a file which is larger than 8k blocks, it is
2216guaranteed to be non-contiguous.
2217
2218In mke2fs, print a warning message if a user tries to format a whole
2219disk (/dev/hda versus /dev/hda1). If a user really wants to format a
2220whole disk, the -F (force) option forces mke2fs to format a whole disk
2221as a filesytem.
2222
2223Fix a bug in fsck where in some cases it might start checking
2224partitions in the next pass before it finishes checking partitions in
2225the current pass. This still won't cause two partitions on the same
2226disk will be checked, so it's rarely a problem in real life.
2227
2228Patch lsattr so that it won't hang when checking a named pipe.
2229
2230Minor compilation fixes:
2231 * Fix the order of libraries that were linked in debugfs.
2232 * Allow the sources to be compiled with -ansi turned on.
