2==================================
3
4Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
5compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
6handling for child process that die unexpectly. Add a hack to force
7mkfs to create filesystems that won't cause problems with hardware
8that has 2k or 4k minimum blocksize requirements. Read from child
9processes in non-blocking mode, so that the GUI continues to update.
10
11Fix e2fsck so that it returns the appropriate exit code when the root
12filesystem has been changed, so that system's rc scripts will be told that
13the system needs to be rebooted.
14
15Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
16was set, some of the descriptor blocks that should have been written
17out were getting skipped.
18
19Changed e2fsck to force out changes to the backup copies of the
20superblock and block group descriptors when important changes are made
21to those data structures.
22
23Fix a bug where e2fsck could erroneously mark a filesystem as being
24clean if a check of dirty filesystem is interrupted with a ^C. (Bug
25introduced in e2fsprogs 1.28.)
26
27If journal debuging is enabled using --enable-jbd-debug, the debugging
28level is now set via the E2FSCK_JBD_DEBUG environment variable.
29
30If byteswapping support is disabled using configure --disable-swapfs,
31skip the tests which depend on byte-swapping, so that "make check"
32won't bomb out.
33
34Lshattr will now display the indexed directory flag. Also, some of
35the more esoteric compression flags are supressed unless compression
36support has been enabled.
37
38Update man pages.

42=================================
43
44When resizing a filesystem, and inodes need to moved, resize2fs will
45update the inode's ctime field, and the mtime field of the containing
46directories, so that incremental backups using dump/restore will work
47correctly.
48
49In order to avoid spurious errors, e2fsck wil check the last
50superblock write time to determine whether or not it can safely use
51the LOW_DTIME checks to determine if there are inodes on the orphan
52inode linked list that had somehow gotten disconnected. (Addresses
53Sourceforge bug #620980)
54
55Partition in /proc/partitions that being with the string "lvm" are
56considered real partitions even if they do not end with a number.
57
58Fixed a bug in the the uuid generation function, where if /dev/urandom
59is not present, but /dev/random is, and there isn't sufficient
60entropy, the get_random_byte function could spin a loop forever.
61
62E2fsck, mke2fs, etc. will now reliably notice when image files are
63mounted using the loopback interface. (Addresses Sourceforge bug
64#619119)
65
66When flushing buffers (as is done by badblocks, for example) check to
67see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
68FDFLUSH ioctl which causes the MD device driver which causes confusing
69syslog messages about obselete ioctl messages. (Addresses Sourceforge
70bug #545832).
71
72Debugfs's write command now checks to see if the destination filename
73exists before creating it. (Addresses Sourceforge bug #478195.)
74
75When installing man pages, search for compressed man pages using all
76commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
77
78Fixed a bug in fsck where multiple filesystems specified on the
79command were not being checked in parallel due to a logic bug
80introduced to support the FSCK_MAX_INST environment variable.
81
82We have added a new superblock field, s_mkfs_time, which indicates
83when a filesystem was created. It is set via mke2fs, and printed out
84by dumpe2fs, but is not actually touched by the kernel.
85
86Dumpe2fs has been made more robust by not aborting if there is an
87error reading the block/inode bitmaps; instead it will still print out
88the location of the block/inode bitmaps and inode table.
89
90Add support for the an alternative block group descriptor layout which
91allows for on-line resizing without needing to prepare the filesystem
92in advance. (This is the incomat feature flag meta_bg.)
93
94Add support for storing default mount options in the superblock, so
95that the filesystem can be mounted with specific mount options without
96needing to specify them on the mount command line or in the /etc/fstab
97file.
98
99Add support for a new inode flag, which is to be used for indicating
100the top of directory hierarchies for the Orlov block allocator.
101
102Fix e2fsck so that if it creates the lost+found directory, it does so
103with the more apporpriate permissions of 0700. Also change
104mklost+found so that it also creates the directory 0700.
105
106Fixed format bug in e2fsck if NLS is in use.
107
108Add a German translation for e2fsprogs's NLS support.
109
110Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
111the beginning of the inode table. This won't matter much, since if
112there is a bad block at the beginning of the inode table, the root
113directory won't be available. But at least e2fsck won't crash in this
114case.
115
116Fixed endian problems in the htree code for e2fsck and debugfs.
117
118When byte-swapping a filesystem on a PPC architecture, byte-swap the
119bitmaps since the historical big-endian ext2 variant had byte-swapped
120bitmaps, and the ext2fs library assumes this. This fixes the
121regression test suite on PPC machines.
122
123Fix e2image so that it handles a bad block in the inode table
124appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -0400125
126E2fsck now uses a more sophisticated algorithm to salvage corrupted
127directories that recovers more information in the corrupted directory
128block.
129
130E2fsck now performs additional consistency checks on indexed (HTREE)
131directories.
132
133Fix bug where efsck might get confused about whether a completely
134empty directory block is an empty leaf block or an interior htree
135node. This could cause e2fsck to get confused into think that a valid
136indexed directory was corrupted.
137
138E2fsck no longer creates an empty directory entry at the end of a
139directory block when optimizing a directory. This would cause some
140earlier versions of the dxdir kernel code to corrupt the directory
141when attempting to split a node containing an empty directory entry.
142
143E2fsck could sometimes in rare circumstances leave the indexed flag
144set after a small directory was optimized by compressing it instead of
145indexing it. (This should never happen in real life, since
146directories that small wouldn't have been indexed, but better safe
147than sorry.)
148
149E2fsck now only updates the master superblock in all cases. This
150slightly shortens its run time.
151
152Ext2ed can deal with directory entries of length 0; previously it
153would get stuck in an infinite loop.
154
155Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
156specifiers. (Sourceforge patch #613447)
157
158Badblocks will now work correctly on read-only devices such as
159CD-ROM's. (Sourceforge patch #600451)
160
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500161Updated and clarified man pages. (Addresses Debian bug #167108)
Theodore Ts'od5e78102002-09-30 11:33:36 -0400162
163
Theodore Ts'oc6633052002-09-24 01:26:50 -0400164E2fsprogs 1.29 (September 24, 2002)
165===================================
166
167Fixed a bug in e2fsck which could corrupt a directory when optimizing
168it (via the -D option) or rebuiliding the hash tree index with a 1 in
169512 probability, due to a fence post error.
170
171Fixed a bug in the LVM support code which caused LABEL='xxx' not to
172work correctly.
173
174Mke2fs now enables the directory indexing flag by default. (Since
175this is a compatible feature flag, it's safe to do so.)
176
177Tune2fs will support setting the directory indexing feature flag. It
178will automatically set up the default hash algorithm and hash seed
179fields in the superblock.
180
181If the bone-headed user enters the root filesystem twice in
182/etc/fstab, the -R option which skips the root filesystem will skip
183all of them. (Addresses Debian bug #159423). Note! This is not a
184precedent for dealing intelligently with any other kind of doubled
185entry in /etc/fstab!
186
187
188Programmer's notes:
189-------------------
190
191Removed perror declaration in lib/et/internal.h. All modern systems
192can be expected to define perror() these days. Besides, the lib/et
193code wasn't using perror at all anyway. :-)
194
195
Theodore Ts'ob7bad612002-08-31 03:00:33 -0400196E2fsprogs 1.28 (August 31, 2002)
197================================
198
199Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
200for setting the htree flag is not included yet, although it can be
201manually turned on via the debugfs program.
202
203Clarified e2fsck error message which is printed when it cannot find
204sufficient contiguous block when relcating filesystem metadata.
205
206Added support for building an EVMS plugin module for ext2/3. This
207module is substantially the same as the EVMS module shipping with EVMS
2081.1, with one or two bugfixes. E2fsprogs can also build this plugin
209for use with EVMS 1.0 (which did not include the ext2 plugin module),
210if the configure --enable-old-evms flag is given.
211
212Fsck will search through EVMS volumes when trying to resolve
213filesystem specifications such as LABEL=xxx or UUID=xxx.
214
215Added a new utility program, /sbin/findfs, which will return
216filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
217the device name.
218
219Update and clarified various man pages. (addresses Debian Bug #145044,
220#146437, #131350, #151990, #144621, #141938)
221
222If there are no filesystems specified on fsck's command line, fsck now
223treat that as if the -As options were given. Previously it would
224simply do nothing. (Addresses Debian Bug #153102)
225
226Mke2fs no longer treats a failure to be able to clear the MD signature
227at the end of the filesystem as a fatal error. (Addresses Debian Bug
228#155007)
229
230The e2p library functions (which are used by lsattr and chattr) now
231double check to make sure the file is a regular file or directory
232before attempting to use the ext2 ioctls. Some device drivers
233unfortunately respond to the ext2 ioctl's with unknown behaviour.
234(Addresses Debian Bug #152029).
235
236The extended attribute handling has been updated to correspond with
237the latest V2 bestbits ACL code.
238
239Fixed bug in e2fsck which caused it to not clear the dtime field when
240processing truncated inodes on the orphan list. This could cause data
241loss(!) if a filesystem is rebooted before a truncate has been
242committed.
243
244E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
245algorithms. This makes e2fsck much faster in the case of severely
246corrupted filesystems where a large number of blocks are claimed by a
247large number of inodes. (Thanks to the 2.5 IDE device driver for
248inspiring this work.)
249
250Resize2fs has been significantly sped up when shrinking and expanding
251a filesystem by a very small number of blocks (for example, when EVMS
252is converting a partition to be an EVMS legacy volume).
253
254Added a new option to e2fsck, -D, which will optimize or compress all
255of the directories in the filesystem.
256
257E2fsck now catches SIGINT and SIGTERM to make sure it will can
258properly clean up and only exit at safe points. Fsck will pass
259SIGINT/SIGTERM to its child processes, and wait until they have all
260exited before it exits.
261
262The uuid parsing code in the uuid library now properly complains when
263an illegally formated uuid is presented to it. (Addresses Debian bug
264#152891)
265
266Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
267and 2.4.17, since the workaround can cause problems when using a 2.4
268kernel with an old version of glibc built with the 2.2 headers.
269
270Fixed a bug in mke2fs where it wasn't properly clearing the initial
271superblock used by other filesystems. (Addresses Debian bug #147256.)
272
273Added support for the synchronous directory feature written by Andrew
274Morton.
275
276The debugfs program can delete directories using the rmdir command.
277
278Add support for 8k and 16k filesystems (for systems with page sizes
279that are greater or equal to 8k or 16k, respectively). Note that
280these filesystems can not be mounted on x86 systems, or other systems
281with only 4k page sizes, due to limitations in the current Linux VM
282code.
283
284Resize2fs requires that the filesystem state be valid and have no
285errors; otherwise, e2fsck -f must be run first. (Previously it simply
286required that the last fsck time be greater than the last mount time.)
287
288Configure now defaults the man pages directory to /usr/share/man on
289Linux systems.
290
291E2fsck now offers to truncate inodes which contain too many blocks (so
292that i_blocks would overflow. Also fixed handling of large sparse
293files.
294
295E2fsck now more completely checks for symlink validity, including
296requiring NULL termination and length checks.
297
298E2fsck will offer to try forcing a disk write to remap a bad block
299after finding a read error when reading a filesystem metadata block.
300
301Fixed a bug in debugfs which caused the -b and -s options to crash
302debugfs, as well as breaking the testb, setb, and clearb functions.
303
304Added a bmap command to debugfs which calculates the logical to
305physical block mapping for a particular inode.
306
307Fixed a bug in code which checked to see if a device was mounted which
308sometimes (rarely) failed in the case of a plain file.
309
310Fixed a bug in resize2fs where when it reported an error, it would
311print a message erroneously indicating that the filesystem had been
312resized before it aborted.
313
314When resizing a plain file which is smaller than the requested size,
315resize2fs will attempt to extended the file so that programs like
316e2fsck will not complain that the file is too small.
317
318Resize2fs will print the actual new size of the filesystem when it is
319finished resizing.
320
321Fixed a bug in debugfs where "ls -l" would report incorrectl file type
322information on big-endian systems.
323
324
325Programmer's notes:
326-------------------
327
328Fixed collisions with C++ reserved words.
329
330Added portability fixes for building e2fsprogs on the HURD and AIX.
331
332Added the ext2ed program for creation of test cases. (ext2ed has many
333limitations and bugs which make it unsuitable for production use.)
334
335The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
336flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
337name_len field is byte swampped on big-endian machines, since in the
338V2 structure, name_len is a char field which is doesn't need to be
339byte swapped --- except if an old-style kernel had byte-swapped the
340name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -0500343E2fsprogs 1.27 (March 8, 2002)
344==============================
345
346The warning messages for mke2fs now go to standard error.
347
348Fixed to make sure "make check" runs all of the test programs with
349LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
350
351The mke2fs program checks the boot sector for the BSD disk label, and
352avoids erasing it if it is there.
353
354Fixed a bug in e2fsck which caused it to core dump if the journal
355inode was missing when it was supposed to be there.
356
357E2fsck now prints ranges in pass 5 when printing deltas for the block
358and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500359
360Debugfs's "ls -l" command now will print out the file type information
361in the directory entry.
362
363Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
364mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
365
366Debugfs can now examine the experimental directory indexing
367information.
368
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500369Fixed bug in debugfs which caused it to core dump if modify_inode is
370called without an open filesystem.
371
372The debugfs lsdel command now runs its output through a pager first.
373
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500374When installing manual pages, remove the compressed manual pages first.
375
376Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
377
378Fix the 2.4 resource limitation workaround introduced in 1.26 which
379actually broke things on mips32, sparc32, and Alpha platforms.
380
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500381Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
382(which is required by the newer libintl libraries).
383
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500384Programmer's notes:
385-------------------
386
Theodore Ts'oa8e77242002-03-08 03:12:14 -0500387Fixed various gcc -Wall complaints.
388
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500389Fixed a few memory leaks in the e2fsck journaling code, and in the
390ismounted code checking for a swap device.
391
392Add new inode I/O abstraction interface which exports an inode as
393an I/O object.
394
395Exported ext2_file_flush as a public interface.
396
397In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
398
399Lots of small random portability fixes to make e2fsprogs build under
400AIX --- even without the 5L compatibility toolkit, and even using the
401uber-crippled AIX native C compiler.
402

Theodore Ts'o06987392002-02-03 01:36:54 -0500404E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500405=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500406
Theodore Ts'o446314f2001-12-24 15:22:27 -0500407Dumpe2fs will keep going now if the bad block inode can't be read.
408(Previously it stopped with a fatal error.)
409
410E2fsck will now give an opportunity to run the journal even if the
411recovery flag is not set. This is the default behaviour if e2fsck is
412using a backup superblock, since the needs_recovery flag will never be
413set in the backup superblock copies.
414
415E2fsck now automatically finds the backup superblock/group descriptors
416even when the primary superblock is completely destroyed for 2k and 4k
417filesystems. (Previously it just guessed/assumed that we were dealing
418with a 1k filesystem in that case, and users had to manually specify
419the backup superblock number.)
420
421Fixed a bug in e2fsck where it dereferences a null pointer when there
422is a problem opening a filesystem in preen mode.
423
424E2fsck now handles external journals correctly; previously it trashed
425the external journal device if the journal needed to be replayed.
426
427Work around ulimit incompatibility problem caused by recent 2.4
428kernels; the unix IO module will automatically try to set any resource
429limits to be infinite on startup.
430
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500431Fixed a bug in e2fsck where it wasn't allocating a new block or inode
432bitmap if it wasn't present and the blocksize was 2k or 4k.
433(Addresses Debian Bug #116975)
434
435E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
436clearing the new V2 fields if they do not make sense or if the ext3
437superblock is version 1 superblock.
438
439E2fsck will automatically relocate the ext3 journal from a visible
440file (i.e., /.journal) to an hidden inode if the filesystem has been
441opened read/write. This allows the users to add a journal while the
442filesystem is mounted, but the next time the system is rebooted, the
443journal file will disappear. This avoids problems with backups,
444stupid operators with superuser bits, etc.
445
446Fix a bug in fsck where it would not support a filesystem type of
447"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
448
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500449Fsck now supports fstab entries of the form "ext3,ext2". It will also
450automatically identify reiserfs filesystems.
451
452The number of processes spawned by fsck can now be limited using the
453FSCK_MAX_INST environment variable.
454
Theodore Ts'o446314f2001-12-24 15:22:27 -0500455Fsck now searchs the LVM proc hierarchy to find logical volumes which
456should be searched for UUID and label information.
457
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500458Work around a bug in 2.4.10+ kernels by trying to unset the filesize
459limit if at all possible, when opening a block device. (The filesize
460limit shouldn't be applied against writes to a block device.)
461
Theodore Ts'o446314f2001-12-24 15:22:27 -0500462In mke2fs and e2fsck, specifying the -c option twice will now do
463a read/write test on the disk. Update the man pages to encourage
464using the -c option, and to discouraging running badblocks separately,
465since users tend to forget to set the blocksize when running
466badblocks.
467
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500468Mke2fs now automatically clears the immutable attribute on a
469pre-existing .journal file left over from a previous failed attempt to
470add a journal to an alreadyy-mounted filesystem.
471
472Fixed mke2fs's exit codes to consistently indicate when the mke2fs
473operation failed.
474
Theodore Ts'o446314f2001-12-24 15:22:27 -0500475Mke2fs now creates the lost+found directory with permissions of 0700,
476so that files that had previously lived in protected directory are
477safe if they get dropped in lost+found and the system administrator
478doesn't deal with immediately. (Addresses Debian #bug 118443)
479
480Mke2fs and e2fsck (and all programs that use the
481ext2fs_check_if_mounted function) will now properly identify that a
482device is mounted, even in cases where devfs has confused things with
483multiple devices names with the same identity, or if a dim-witted
484system administrator has done something stupid like creating device
485file aliases in their home directory. Also now checks for swap devices
486by using /proc/swaps. (Addresses Debian bug #106622)
487
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500488Added a new option (-T) to tune2fs which sets the time a filesystem
489was last checked.
490
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500491Speed up e2image when creating sparse raw image files by optimizing
492away excess lseek() system calls.
493
494Fix support of large (> 2GB) files when used as a filesystem in
495mke2fs, tune2fs, debugfs, and findsuper.
496
497Debugfs's stat and icheck commands now properly deals with large (>
4982GB) files.
499
500Debugfs's set_super_value command now prints out the list of valid
501superblock fields which can be set using the command.
502
Theodore Ts'o446314f2001-12-24 15:22:27 -0500503Debugfs's rm and kill_file command now updates the superblock free block
504and inode counts, thus keeping the filesystem consistent.
505
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500506Debugfs's lsdel command now takes an optional argument which allows
507the user to only see the most recently deleted files.
508
509A new command (undel) was added to debugfs which automates
510undeleting a deleted inode and linking it back to a directory.
511
512Debugfs's ls command now takes a new option, -d, which lists
513deleted directory entries.
514
515Debugfs's testb, freeb, setb, and find_free_block commands now take an
516optional count argument.
517
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500518Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
519be used to signal that a particular inode should not be eligible for
520tail-merging --- this is needed for programs like LILO.
521
522The findsuper (an unreleased, uninstalled utility program) has been
523improved to add extra validity checks and to add a progress meter.
524(It is still an unsupported program; the officially supported way to
525recover from a trashed partition table is to use gpart; findsuper is
526for wizards only. :-)
527
528Debugfs was fixed to compile with "configure --disable-swapfs".
529
Theodore Ts'o446314f2001-12-24 15:22:27 -0500530Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500531
532Added new translation file for Turkish.
533
Theodore Ts'o446314f2001-12-24 15:22:27 -0500534Programmer's notes:
535-------------------
536
537Fix general gcc -Wall complaints.
538
539E2fsprogs (mostly) works with the dietlibc.
540
541The programming texinfo file has been expanded to include description
542of additional libext2fs functions. (Still not compeltely done, but a
543lot of the more important functions have been documented.)
544
545Added a umask structure to struct_ext2_filsys, which currently only
546modifies the behaviour of ext2fs_mkdir(), but if we add any file
547creation functions to libext2fs, we should also make sure they respect
548the umask setting.
549
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500550The build-rpm script was fixed to be a bit more safe.
551
552The tests' Makefile now has a way of automating test case creation
553for e2fsck, using "make testnew".
554
555Created a new function, ext2fs_dir_iterate2 which passes more
556information to the callback function (identical to the one used by
557ext2fs_dblist_dir_iterate). The directory iterator functions take a
558new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
559directory entries. If the directory entry is deleted, the callback
560function will be called with the entry paraemter set to
561DIRENT_DELETED_FILE.
562
563Added new functions, ext2fs_inode_alloc_stats and
564ext2fs_block_alloc_stats, which takes updates block/inode allocation
565statistics in the bitmaps, block group descriptors, and superblock
566when inodes or blocks are allocated or deallocated.

Theodore Ts'od08a4ce2001-09-20 09:47:42 -0400569E2fsprogs 1.25 (September 20, 2001)
570===================================
571
572This is primarily a bug-fix release; no new features were added, but
573there are a number of embarassing bug fixes and cleanups applied.
574
575Fix a bug mke2fs which causes stack garbage to be written to disk when
576zapping disk sectors. (This bug could cause mke2fs to core dump for
577some kernels, I suspect with security enhancement patches.)
578
579Remove unneeded #include of <linux/config.h> which was breaking
580building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
581
582Updated tune2fs man page to reflect the fact that adding or removing a
583journal doesn't require running e2fsck.
584
585Remove use of AC_REQUIRE from autoconf which had been used to prevent
586AC_CANONICAL_HOST from being called twice; unfortunately this causes
587recent autoconf to bomb out since they don't allow AC_REQUIRE to be
588used outside of autoconf macros. Fortunately, it doesn't seem to be
589necessary any more, anyway.
590
591E2fsck will now not fall back to an alternate superblock if the user
592specifies the superblock location explicitly on the command-line.
593This allows easier recovery from a situation where the primary
594superblock and block groups are slightly corrupted, but the backup
595superblocks are completely broken.
596
597Fix problem which caused compile_et and mk_cmds to blow up if
598e2fsprogs was in a directory with a pathname that contained spaces.
599
600We are now more paranoid about checking the entry in /etc/mtab to make
601sure the filesystem is really mounted, since some broken distributions
602(read: Slackware) don't initialize /etc/mtab before checking non-root
603filesystems. (Slackware also doesn't check the root filesystem
604separately, and reboot if the root filesystem had changes applied to
605it, which is dangerous and broken, but there's nothing I can do about
606that.)
607
608Make UUID library C++ friendly by adding appropriate extern "C"
609declarations and using const in the function declarations.
610
611Fix up the com_err texinfo file so that it can product a valid info
612file (previously, it could only be used to generate paper
613documentation using texinfo.tex).
614
615
Theodore Ts'ofb707752001-09-04 15:00:37 -0400616E2fsprogs 1.24a (September 2, 2001)
617===================================
618
619Fix brown-paper bug in mke2fs which caused it to segfault when
620printing the version string.
621
622
Theodore Ts'o109624a2001-08-31 00:59:55 -0400623E2fsprogs 1.24 (August 30, 2001)
624================================
625
626Revert the BLKGETSIZE64 support, since for some distributions, this
627ioctl has been used by an unofficial kernel patch to update the last
628sector on the disk, and this was causing disk corruption problems as a
629result.
630
631Mke2fs is now more careful about zapping swap space signatures and
632other filesystem/raid superblock magic values so that programs like
633mount who try to use hueristics to determine the filesystem type of a
634partition are less likely to be confused.
635
636E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
637regular file (since Andreas Dilger's on-line resizing tools will set
638its mode bits).
639
640Fixed some minor texinfo, man pages nits for spelling errors,
641texinfo warnings, etc. (Addresses Debian bug #110621.)
642
643E2fsprogs program no longer print the filesystem version number
644(i.e. 0.5b), since it only confuses people and doesn't serve any real
645purpose.
646
647E2fsck will once again compile under libc5, since it will supply its
648own version of strnlen if necesssary.
649
650mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
651when specifying the external journal device. tune2fs will also search
652devices looking for the externla journal debice when removing.
653
654E2fsprogs 1.23 (August 15, 2001)
655================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400656
657Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -0400658correctly handle a filesystem with EA's and check the EA blocks for
659corruptions.
660
Theodore Ts'od494bba2001-08-09 06:14:42 -0400661E2fsck's symlink sanity checking has been cleaned up. It now checks
662the i_size value of fast symlinks, and checks for immutable flags
663being set of symlinks, etc.
664
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400665E2fsck now offers to clear inodes which are special files that have a
666non-zero i_blocks or i_size field. (The i_size field check was in the
667previous version of the code, but due to a bug it didn't offer to
668clear the inode unless i_size and i_size_high were both non-zero.)
669
Theodore Ts'od494bba2001-08-09 06:14:42 -0400670E2image can now create "raw" image files, which only contain the
671filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
672debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -0400673
674Add support for the 64-bit block device patches.
675
676Fixed bugs in creating external journals with a 1k blocksize.
677
Theodore Ts'od494bba2001-08-09 06:14:42 -0400678Add initial support for external journals (so long as the external
679journal only supports a single filesystem) in e2fsck.
680
681Remove requirement for needing to run fsck on a filesystem after
682removing a journal (either internal or external).
683
Theodore Ts'obf16d102001-07-27 22:20:06 -0400684The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400685
686Speed up the check of an ext3 filesystems by avoiding a needless flush
687of all of the superblock and block group descriptors.
688
Theodore Ts'od494bba2001-08-09 06:14:42 -0400689Speed up creating an internal journal using tune2fs in the case where
690the filesystem has a lot blocks already allocated.
691
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400692Tune2fs has been fixed to make sure that only error messages go to
693stderr, and normal message go to stdout. (Addresses Debian bug #108555)
694
Theodore Ts'od494bba2001-08-09 06:14:42 -0400695Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400696now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -0400697
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400698Add support in fsck for the filesystem type "auto".
699
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400700Fsck -A will not try to interpret device names for filesystems which
701have a pass number is 0. (Addresses Debian bug #106696).
702
703Fsck prints a warning message if now valid filesystems are passed to
704it. (Addresses Debian Bug #107458.)
705
Theodore Ts'o9249d982001-07-20 18:14:10 -0400706E2fsck now gives an explicit warning if there filesystem still has
707errors at the end of the run. (Addresses Debian bug #104502)
708
Theodore Ts'od494bba2001-08-09 06:14:42 -0400709E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400710reflects an error. E2fsck will also not run the orphan list if the
711filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -0400712
713E2fsck now prints the number of large files when given the -v option.
714
715Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -0400716
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -0400717Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -0400718
Theodore Ts'od1ef5c32001-07-20 12:35:11 -0400719
Theodore Ts'o19d6b542001-06-23 00:13:09 -0400720E2fsprogs 1.22 (June 22, 2001)
721==============================
722
723Fixed a bug in e2fsck's handling of orphan inodes which are special
724files (i.e., block/character device files, named FIFO's, etc.).
725
726Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
727tune2fs to fail at adding a journal to a mounted filesystem.
728
729Fixed a few big-endian bugs in e2fsprogs
730 * The directory block functions were accidentally reporting
731 some directories as corrupted when they weren't.
732 * If e2fsprogs is compiled --disable-swapfs, the C language
733 equivalents weren't being included for big-endian platforms.
734 (Fixes Debian bug #101686).
735
736Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
737
738Programmer's notes:
739-------------------
740
741Use platform independent method of defining the BLKFLSBUF and FDFLUSH
742ioctls, and allow them to be defined for non-i386 platforms.
743
744The uuid.h header file is now protected against multiple inclusions.
745
746E2fsprogs is now being developed using BitKeeper. Changed the test
747scripts to deal with BK's stripping CR characgters from text files,
748and changed the top-level Makefile.in to avoid including BitKeeper
749files when generating the source tarball.
750
751
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000752E2fsprogs 1.21 (June 15, 2001)
753==============================
Theodore Ts'o767de092001-06-02 01:20:18 +0000754
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000755Added new configure flags which allow a subset e2fsprogs to be built;
756this is most useful for boot floopies, since the resulting shared
757libraries and programs are slimmed down by removing features that
758aren't necessary for a boot floppy. The new flags that were added
759are: --disable-swapfs, which removes support for byte swapping old
760legacy PPC/68k filesystems, --disable-debugfs, which removes support
761for debugfs from the libext2fs library, --disable-imager, which
762removes support for the e2image program, and --disable-resizer, which
763removes support for resize2fs.
764
765E2fsck now prints the number of mounts or days elapsed since the last
766check when e2fsck is forced to check an otherwise clean filesystem.
767
768Tune2fs now prints an informative message about how often a filesystem
769will be checked when adding a journal to the filesystem, to remind the
770user that he/she may want to adjust those parameters using tune2fs
771-c/-i.
772
773Worked around hurd brain-damage which causes e2fsck to sometimes
774believe a filesystem is the root filesystem based on device numbers
775(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
776violation).
777
778Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
779erroneous error with the -F option was specified.
780
781Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000782ext3 0.7a.
783
Theodore Ts'o767de092001-06-02 01:20:18 +0000784Fixed two bugs in e2fsck's handling of dup block handling, dealing
785with relatively uncommon edge cases: a directory with an indirect
786block which is claimed by another file, and when the last inode in the
787filesystem has blocks claimed by another file.
788
Theodore Ts'o5a9c0362001-06-02 04:55:57 +0000789E2fsck now checks to see if the i_size field of a fast symlink is too
790big, and offers to clear the symlink if so.
791
792E2fsck now checks to see if i_size_high of special files is non-zero,
793and offers to clear i_size_high.
794
Theodore Ts'o767de092001-06-02 01:20:18 +0000795Fix e2fsck's handling of incompatible journal flags so that the user
796has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +0000797entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +0000798
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000799Fixed a bug in fsck which could cause it to core dump if a mix of
800standard and non-standard device names are used in /etc/fstab.
801(Debian bug #100559)
802
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000803Fixed a bug in debugfs which caused read errors when copying a file to
804not be noticed.
805
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000806The debugfs set_super_value command can now modify the s_lastcheck field.
807
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000808Fixed a bug in lsattr and chattr which was accidentally introduced in
8091.20 to support > 2GB files; both lsattr and chattr wasn't reading
810directories correctly because the change modified the layout of struct
811dirent to be incompatible with the libe2p shared library.
812
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000813Cleaned up the mke2fs manual page and included a discussion about why
814it's good to periodically check the filesystem even when journaling is
815enabled.
816
Theodore Ts'o767de092001-06-02 01:20:18 +0000817Programmer's notes:
818-------------------
819
820Fix general gcc -Wall complaints.
821
822The types needed by the ext2 header files are now provided by
823lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
824
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000825Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000826in ext2_types.h. Also, if linux/types.h has already been defined,
827don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000828
Theodore Ts'o767de092001-06-02 01:20:18 +0000829Fixed make depend script so that it automatically corrects the
830pathname cleanups performed by make -M, so I don't have to fix them up
831by hand.
832
833Fixed the d_loaddump test case to be more robust, and not depend on
834bash'isms.
835
836Removed debugfs's dependence on pread(), which was accidentally
837intrudced in e2fsprogs 1.20
838
Theodore Ts'oc05b5522001-06-08 12:03:36 +0000839Fixed a performance bug in the libext2fs's icount routine; the size
840estimate of the icount array was incorrectly being calculated.
841
Theodore Ts'ob90b8262001-06-15 22:54:34 +0000842Removed use of the badblocks compatibility functions in the e2fsprogs
843programs.
844
845Added paranoia code which protects against strange cases where /etc
846isn't on the root filesystem, or if /etc/mtab doesn't exist.
847
848The header file ext2_types.h is now installed.
849
850Autoconf is used to determine when we are on big-endian machines,
851instead of doing run-time tests, to save a few bytes of code.
852
853The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
854functions are no longer inline functions, which saves space and
855doesn't really cost any real performance.
856
857The ext2fs library no longer depends on the e2p library. (What need
858there was of it --- namely, fsetflags, was coded in-line).
859
860Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
861when the user is stupid and tries compiling the package using "make
862install" as root.
863
864Miscellaneous code cleanups:
865 * Added missing files from Makefile.in's SRCS file, so that
866 their dependencies would be properly calculated.
867 * Removed redundant code
868 * Fixed comments in code

Theodore Ts'o5a009bb2001-05-21 05:27:45 +0000872E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000873=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +0000874
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000875Add support for replaying the ext3 journal purely in user mode,
876including handling the orphaned inode list. Used code contributed by
877Andreas Dilger, with bug fixes and the orphaned inode handling done
878by Theodore Ts'o.
879
880The mke2fs and tune2fs programs can create or modify a filesystem to
881include an ext3 journal. Tune2fs also can be used to remove an ext3
882journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +0000883
884E2fsck will now check for the existence of a linked list of orphan
885inodes in the superblock, and clear those inodes before starting the
886rest of the filesystem check (but after the journal playback).
887
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000888E2fsck now validates the file descriptor passed to the -C option,
889which saves against the completion bar getting written to an
890unexpected location, such as the disk being checked. (Debian
891bug/wishlist #55220)
892
893E2fsck will now bump the filesystem revision number from zero to one
894if any of the compatibility bits are set.
895
896Fixed a bug where a badly corrupted directory on a big endian system
897could cause e2fsck to die with a bus error. The
898ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
899the ext2 library now does alignment sanity checks on the rec_len field
900of the directory entry before using it.
901
902The ext2 library has been enhanced to make tune2fs safe to run on
903mounted filesystems. (Users could usually get away with using tune2fs
904on mounted filesystems before, but with the advent of ext3 and
905journaling, it became important to make tune2fs was *really* safe for
906use even when the filesystem being modified is mounted.) E2label is
907now implemented by tune2fs using an argv[0] dispatch, so that e2label
908is also now safe for use on mounted filesystems.
909
910Added a new program, e2image, which creates a backup of critical ext2
911filesystem data structures. The generated image file can be examined
912using dumpe2fs and debugfs. In the future, e2fsck will be able to use
913the image file to help recover very badly damaged filesystems.
914
915Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
916no longer cause e2fsck to bomb out. Also treat files > 2GB as being
917large file when deciding whether or not the filesystem has large files.
918
919Fixed lsattr and chattr so that they work correctly on large files.
920(Fixes Debian bug #72690.)
921
922Removed limitation in get_device_size() which imposed a one terrabyte
923filesystem limitation. (Most 2.2 kernels still have a signed int
924problem which cause 1 TB block device limitation. Fortunately, the
925kernel patches to fix this are much easier than fixing the 2TB
926limitation in the kernel. :-)
927
928A max_mount_count of zero is now treated as if no mount count were
929set. (Previously, no mount count was indicated by using -1, and a
930mount count of zero caused e2fsck to always be run.)
931
Theodore Ts'o77648562001-05-14 13:04:44 +0000932Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000933
934Mke2fs now adds some randomness in s_max_mount_count so that multiple
935filesystems won't be all checked at the same time under normal
936operations.
937
Theodore Ts'o5570a652000-08-21 01:23:39 +0000938Fixed bug in the progress bar printing code which could cause e2fsck
939to core dump on an illegal filesystem.
940
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000941Fixed bug in fsck which could allow more than one instance of e2fsck
942to be printing a progress bar. (Debian bug #65267)
943
Theodore Ts'o5570a652000-08-21 01:23:39 +0000944Fsck using a UUID or a LABEL specifier will work even if devfs is
945compiled into the kernel and not mounted. If the pathnames in
946/proc/partitions are incorrect, fsck will search /dev for the correct
947device (using the new ext2fs_find_block_device library function).
948Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000949found when they are in use. Support has also been added to support
950additional IDE disks and the DAC 960 device names. (Debian bug #94159)
951
952Fixed a bug in fsck which caused it not deal properly with 16
953byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +0000954
Theodore Ts'o5a009bb2001-05-21 05:27:45 +0000955Fsck's -t option has been made a lot more flexible. The semantics for
956what happens if a comma-separated list to fsck has been regularized,
957and it is now possible to filter what filesystems will get checked
958based what is in the filesystem's fstab entry's option field. (Debian
959bug #89483.)
960
Theodore Ts'o5570a652000-08-21 01:23:39 +0000961The dumpe2fs program can now print out the group description
962information in hex, and also prints the location of the superblock and
963block group descriptor for those block groups that have them.
964
965Mke2fs now clears the ext2 superblock before it starts creating a
966filesystem, so that the superblock magic number is only written if the
967filesystem creation process successfully completes.
968
969The debugfs program's stat command now pretty-prints the blocks used
970by an inode so that it's more compact and informative.
971
972The debugfs stats command now uses the same libe2p code (which is used
973by dumpe2fs) to print the superblock header information. This is more
974complete, and it avoids a bit of code duplication.
975
976Added a new debugfs command, set_super_value (ssv) which allows the
977user to set arbitrary superblock fields.
978
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +0000979Debugfs was extended to support inode numbers in hex (by prefixing
980them with 0x), and so that modify_inode can set the inode generation
981number. Also, there is now a new function command called logdump
982which will dump an ext3 journal.
983
984Fixed a bug in debugfs so that quitting out of the pager doesn't kill
985debugfs.
986
987Debugfs's dump command now stops immediately upon reporting a disk
988read error. (Fixed a bug in ext2fs_file_read library routine which
989caused debugfs not to stop.) (Debian bug #79163)
990
991On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
992checked before /etc/mtab is used, since /proc/mounts is more likely to
993be accurate.
994
995Added portability fixes for Solaris and Linux/ia64.
996
997Various manual pages were clarified and cleaned up. (Fixed debian
998bugs #63442, #67446, and #87216)
999
Theodore Ts'o5570a652000-08-21 01:23:39 +00001000
1001Programmer's notes:
1002-------------------
1003
1004The e2fsck message printer now supports %Iu and %Ig, which will print
1005out the inode's user and group owners, respectively.
1006
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001007E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
1008that no longer dependent on the system having the correct version of
1009the kernel header files.
1010
Theodore Ts'o5570a652000-08-21 01:23:39 +00001011Added a new function to libext2, ext2fs_find_block_device(), which
1012searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
1013device given its device number.
1014
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001015Added a new function to libext2, ext2fs_sync_device, which centralizes
1016all of the places which might try to use the BLKFLSBUF or FDFLUSH
1017ioctls (and usually failing to define them since the system header
1018files don't usually do this for us, and we're trying to avoid usage of
1019kernel include files now).
1020
Theodore Ts'o5570a652000-08-21 01:23:39 +00001021Added new utility programs in tests/progs: random_exercise and
1022hold_inode. They aren't built by default; they're useful for
1023exercising ext3 filesystem code.
1024
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001025Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
1026the filesystem close functions to only update the superblock, and to
1027not touch the block group descriptors. Needed by tune2fs when
1028modifying a mounted filesystem.
1029
1030Got rid of struct ext2fs_sb and replaced it with the standard struct
1031ext2_super_block from include/linux/ext2_fs.h. Note: this may break
1032source (but not binary) compatibility of some users of the ext2
1033library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00001034replace of struct ext2fs_sb with struct ext2_super_block, and include
1035the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001036
1037The ino_t type has been renamed ext2_ino_t to protect applications
1038that attempt to compile -D_FILE_OFFSET_BITS=64, since this
1039inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
1040unexpected ABI change.
1041
1042The Makefiles have been reworked so that "make check" can be run from
1043the top-level Makefile.
1044
1045Fix general gcc -Wall complaints and removed dead code.
1046
1047Remove use of NOARGS, because we assume everyone does ANSI C these
1048days.
1049
1050Added build-rpm script from sct.
1051
1052New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
1053to support e2image.
1054
1055New function ext2fs_flush_icache which must be called if the
1056application program modifies the inode table blocks without going
1057through ext2fs_write_inode() interface.
1058
1059New ext2fs_check_mount_point() function, which will return the mount
1060point of a device if mounted.
1061
1062The io_channel abstraction now has an optional interface,
1063io_channel_write_range, which allows specific byte ranges to be
1064written.
1065
1066The unix_io IO channel now supports write-through caching, so that
1067journal creation is more efficient.
1068
1069Added x86 assembly language routines to support byte swapping, to
1070reduce executable size.
1071
1072Fixed bug in the utility program subst so that it's possible to
1073replace a substitution variable with a zero-length string.
1074
1075Fixed numbering e2fsck pass1 problem numbers; an extra zero had
1076slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001077
Theodore Ts'ob777e262000-07-27 01:39:23 +00001078E2fsprogs 1.19 (July 13, 2000)
1079==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00001080
1081Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00001082be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00001083
1084Add experimental support needed for the ext2 compression patches.
1085This requires compiling e2fsprogs with the --enable-compression flag
1086to the configure script.
1087
1088Added ext3 journalling support. E2fsck will run the journal (if
1089necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
1090installed as a symlink to e2fsck. Fsck has been taught about ext3,
1091and treats it the same as ext2 in terms of the progress bar logic.
1092Dumpe2fs will display the superblock journaling information if the
1093filesystem has a journal. The ext2 library will now permit opening an
1094ext3 filesystem with the recovery flag set. This is necessary for
1095on-line dump's to work correctly, but there may be issues with this
1096working well since ext3 is much less agressive about syncing blocks to
1097the filesystem, since they're safe on the journal.
1098
1099Tune2fs and e2fsck have been changed to allow the mount_count check to
1100be disabled by setting max_mount_count to -1. (This was already
1101supported by the kernel.)
1102
1103Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
1104are used for ext3 as well.
1105
1106Added internationalization support for e2fsprogs; must be enabled
1107by passing --enable-nls to configure.
1108
1109Always use the provided ext2fs header files to insulate ourselves from
1110kernel version changes. Which include files are used by e2fsprogs
1111have also been cleaned up to improve portability.
1112
1113Limit the number of times that e2fsck updates the progress bar so that
1114people who are booting using a 9600 baud console don't get swampped by
1115too many updates.
1116
1117Improved the loop detection algorithm in e2sck's pass #3 so that it is
1118much, much faster for large filesystems with a large number of
1119directories.
1120
1121The memory footprint for e2fsck is now slightly smaller than before.
1122
1123E2fsck now checks if special devices have a non-zero size, and offers
1124to clear the size field if it finds such an inode.
1125
1126E2fsck now checks if special devices have the append-only flag set,
1127and offers to clear the inode.
1128
1129E2fsck now properly handles some "should never fail" cases during a
1130bitmap copy in pass5.
1131
1132E2fsck now properly prints control characters in filenames as ^A .. ^Z.
1133
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001134E2fsck now calculates the correct location of the backup superblock in
1135the case of filesystem blocksizes > 1k.
1136
1137Fixed a bug in e2fsck's calculation of the number of inodes_per_block
1138which normally didn't cause problems under most filesystem parameters,
1139but could cause a valid superblock to be rejected in extreme cases.
1140Other checks for validating superblock values were made more
1141stringent.
1142
Theodore Ts'oab146762000-07-07 04:37:35 +00001143Added non-destructive write testing to the badblocks program, courtesy
1144of David Beattie. The badblocks also now has an option to input the
1145current set of bad blocks, so that known bad blocks are skipped to
1146speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00001147feature which causes badblocks to run until it has completed some
1148number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00001149
1150Badblocks now checks to see if the device is mounted and refuses to do
1151the tests involving writing to the device if it is mounted. Also,
1152badblocks now allows the number of blocks to be checked to be
1153defaulted to the size of the partition.
1154
1155Fixed a bug in fsck which didn't allow non-root users to be able to
1156check filesystems if there were any LABEL= or UUID= entries in
1157/etc/fstab.
1158
1159The Hurd doesn't support the filetype filesystem feature. The mke2fs
1160program now makes sure that for the Hurd, the filestype feature is
1161turned off. E2fsck will check to see if the filetype feature is
1162turned on for Hurd filesystems, and offer to turn off the feature.
1163
1164Mke2fs now has a safety check to make sure the number of blocks do not
1165exceed 32 bits even on a 64 bit platform.
1166
1167Really fixed a bug in fsck to allow "fsck -As" to run interactive
1168fsck's. (For those people who like to do interactive fsck's in the
1169/etc/rc scripts!?!)
1170
1171Debugfs has a few new features: the rdump command, which will do a
1172recursive dump of a directory and all of its contents, and the lcd
1173command which does a local chdir (much like the ftp command of the
1174same name). In addition, the debugfs program and the open_filesystem
1175command now takes three new options: -b and -s, which allows the
1176blocksize and superblock location to be specified, and the -c option
1177which is used in catastrophic situations where the block group
1178descriptors are corrupt. If the -c option is specified, debugfs will
1179skip trying to read in the block and inode bitmaps.
1180
1181Debufs's lsdel command was fixed to handle bad blocks in the inode
1182table.
1183
1184A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
11854 digit years.
1186
1187General improvements in error messages
1188
1189 - Mke2fs prints a sane error message if the partition size is zero
1190 (usually because the partition table wasn't reread by the
1191 kernel due to the partition being busy), instead of "invalid
1192 argument passed to ext2 library while initializing superblock".
1193
1194 - Fsck now prints more self-explanatory message if an invalid UUID=
1195 or LABEL= specification is passed to it.
1196
1197UUID library changed to use the LGPL.
1198
1199Fixed a bug in the UUID library where very rapid calls to the
1200time-based UUID generator could cause duplicate UUID's to be returned.
1201This was not a problem for e2fsprogs, but it could be a problem for
1202other users of the library.
1203
1204Make the UUID library more robust in the face of missing or an
1205improper /dev/urandom or /dev/random files.
1206
1207Added some random portability fixes for Solaris.
1208
1209Some minor man page updates.
1210
1211Fixed a memory leak in the ss library.
1212
1213
1214Programmer's notes:
1215-------------------
1216
1217We now try to use lseek64 and open64 from the LFS if possible.
1218
1219The 3rd parameter in e2p's print_flags is now a flags word, instead of
1220a boolean option.
1221
1222The mark and unmark bitmap functions now return the previous state of
1223the bit that was being changed, which is useful for some speed
1224optimizations.
1225
1226The following functions have been added to enhance the badblocks list
1227handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1228ext2fs_badblocks_equal.
1229
1230The ext2 header files now have the latest journalling fields to the
1231superblock.
1232
1233The ext2fs_mkdir function in libext2fs now properly backs out of error
1234conditions robustly.
1235
1236Cleaned up makefiles:
1237 - to cleanly compile with the -j flag.
1238 - so distclean removes all generated files.
1239 - so in case of an error while installing header files, the make aborts.
1240
1241Fix test_script so that it works correctly when compiling in the
1242source directory.
1243
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001244The random UUID generation routine has been made slightly better in
1245the case where /dev/random doesn't exist. (Use of randomly-based UUID
1246is still not recommended if /dev/random doesn't exist, however; it's
1247better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00001248
1249Clean up the build process so it's more friendly in case of missing
1250directories.
1251
1252The ext2fs header file can now be #include'd into C++ programs.
1253
1254The e2p.h header file is now installed.
1255
1256Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
1257
1258
1259
Theodore Ts'o24ded091999-11-10 15:56:16 +00001260E2fsprogs 1.18 (November 10, 1999)
1261==================================
1262
1263Fix a core dumping bug in e2fsck if an imagic inode is present or
1264(more rarely) if the filesystem is badly corrupted enough that e2fsck
1265has to restart pass 1 processing. E2fsck now closes the filesystem
1266before freeing a large number of its data structures, so in the case
1267of future memory faults, at least the fixed filesystem will be fully
1268written out.
1269
1270If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1271imagic inode, it will offer to clear the imagic flag.
1272
1273E2fsck will now offer to clear the immutable flag on special files
1274(device/socket/fifos) when running it in non-preen mode.
1275
1276E2fsck will now set the filetype when creating /lost+found, and when
1277connected orphaned inodes to /lost+found.
1278
1279Debugfs's ncheck and icheck commands now handles the case where there
1280are bad blocks in the inode table without bombing out.
1281
1282The badblocks list processing code has been made more efficiently for
1283appending a large number of (ordered) badblocks to the badblocks list.
1284
1285Some minor man page updates.
1286
1287Fsck now allows interactive e2fsck's when using fsck -As (not a common
1288mode, but some people like to do this in boot scripts for silly reasons).
1289
1290Programmer's notes:
1291-------------------
1292
1293The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1294with the problem code convention.
1295
1296The badblocks list regression test program has been updated to work
1297with previously made API name changes.
1298
1299The ext2fs_free() command now uses the new badblocks API to avoid
1300using the compatibility layer.
1301
1302Added new regression test cases; the run_e2fsck test script now
1303supports the ability for a test case to run a prepratory command
1304before running e2fsck.
1305
Theodore Ts'o28e11941999-10-26 18:17:20 +00001306E2fsprogs 1.17 (October 26, 1999)
1307=================================
1308
1309Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1310infinite loop.
1311
1312Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1313thus potentially causing problems if a binary UUID contained a NULL
1314character.
1315
1316E2fsck now uses stricter checks for directory entries in pass 2:
1317zero-length filenames are not allowed; neither are 8 byte long
1318directory entries.
1319
1320The debugfs "dirty" command now clears the filesystem valid bit.
1321(Previously this just set the dirty-as-in-needs-writing-out-to-disk
1322bit in the in-core superblock image. The new functionality is more
1323what the user expects, and is more useful.)
1324
1325Added a debugging hook to test parallel fsck; if the environment
1326variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1327will be checked in parallel when they normally would not be.
1328
1329Programmer's notes:
1330-------------------
1331
1332Fixed some #ifdef's for compilation under the Hurd OS.
1333
1334Fixed minor W2K compatibility problems.
1335
1336Fixed some miscellaneous GCC warnings.
1337
1338
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001339E2fsprogs 1.16 (October 22, 1999)
1340=================================
1341
1342Fixed a race condition bug in fsck; when printing a progress bar, if
1343checking multiple filesystems in parallel, it was possible for fsck to
1344send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
1345handler, which would cause it to terminate with a signal 10.
1346
1347E2fsck now properly handles filesystems that have the
1348INCOMPAT_FILETYPE feature turned on. It can be used to convert a
1349filesystem into using or not using FILETYPE feature.
1350
1351E2fsck now properly handles filesystems that have the IMAGIC feature
1352turned on (this is used on Linux AFS servers).
1353
1354The mke2fs program now creates filesystems that have the filetype and
1355sparse_superblock features enabled by default, unless it is run on a
1356pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
1357so there is now a new flag -O which allows the user to specify with
1358which features she would like to create the filesystem; "mke2fs -O
1359none" will create a filesystsem compatible with 2.0 kernels.
1360
1361The tune2fs program now has a -O option which allows the user to set
1362and reset "safe" filesystem features. Currently, the only ones which
1363allows to be modified are the filetype and sparse_superblock features.
1364Note setting or clearing either feature will require running e2fsck on
1365the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
1366requires that there is enough free space on the filesystem for the
1367extra superblocks which will be created by e2fsck.)
1368
1369Debugfs can now set and print filesystem features in the superblock
1370using the "features" command. Dumpe2fs will print out the complete
1371set of features when listing the superblock.
1372
1373Dumpe2fs has new options -f (force) and -h (header-only).
1374
1375Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
1376message to come up. This could happen when decrementing or
1377incrementing a link count could result in an overflow.
1378
1379Fixed a bug in e2fsck where the block count on the lost+found
1380directory would not be properly incremented when the directory was
1381expanded to the point where an indirect block needed to be allocated.
1382
1383E2fsck now makes some additional sanity checks on the superblock to
1384avoid crashing or giving a memory allocation error if some of the
1385values in the superblock are unresonable (but the superblock otherwise
1386looks valid).
1387
1388Fixed a bug in e2fsck where a very badly corrupted filesystem might
1389require two passes to completely fix the filesystem. This happened if
1390an inode claimed blocks that was part of the filesystem metadata
1391(typically, when garbage was written into an inode table or indirect
1392block, since this kind of filesystem corruption normally doesn't
1393happen otherwise).
1394
1395On the Alpha, glibc declares st_flags although it isn't actually used;
1396the configure script was improved to detect this case so that
1397e2fsprogs can avoid using the non-functional stat field.
1398
1399The manual pages were updated to use a more consistent formatting
1400style consistent with standard Unix man pages. Mke2fs's man page
1401added documentation for a few previously undocumented options.
1402
1403Fixed minor display bugs in tune2fs and mke2fs.
1404
1405Programmer's notes:
1406-------------------
1407
1408Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
1409
1410Added features to parse and print feature strings into the e2p library.
1411(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
1412
1413ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
1414whose directory entries contain proper filetype information if the
1415filesystem supports it.
1416
1417ext2fs_link() now uses the low 3 bits of its flags parameter to pass
1418the directory entry filetype information. This is used to set the
1419directory entry filetype information if the filesystem supports it.
1420
1421Fixed a bug in ext2fs_expand_dir() where the block count in a
1422directory's inode would not be properly incremented when the directory
1423was expanded to the point where an indirect block needed to be
1424allocated.
1425
1426
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001427E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001428==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001429
1430Add configuration checks so that e2fsprogs will compile cleanly on
1431Linux 2.3 kernels that have renamed i_version to i_generation.
1432
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001433E2fsck now prints a progress/completion bar (and not just a simple
1434spinner) if the -C0 option is requested or if it receives a SIGUSR1
1435signal. Fsck will automatically manage the (potentially muliple)
1436e2fsck processes to print completion bars if it is given a -C option,
1437with the right thing happening if multiple filesystems are being
1438checked in parallel.
1439
1440Mke2fs now has better automatic hueristics to determine the filesystem
1441parameters to be used for a particular filesystem. Added a new option
1442-T which allows the user to specify how the filesystem is to be used,
1443which helps mke2fs do a better job selecting the filesystem parameters.
1444
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001445Mke2fs now creates revision 1 filesystems by default, and with the
1446sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001447not understood by Linux 2.0 kernels, so they will only allow read-only
1448mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001449
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001450Fix bug where if /dev/null couldn't be opened (should never happen),
1451e2fsck would hang in a tight loop.
1452
1453Make e2fsck handle the case where /lost+found isn't a directory.
1454
1455E2fsck now uses mallinfo if it exists to get accurate statistics about
1456its memory usage.
1457
1458Fix bug in e2fsck where it wouldn't check to see if a disconnected
1459inode had any problems before connecting it to /lost+found.
1460
1461Add check to e2fsck so it makes sure that total number of inodes in
1462the filesystem is a sane number.
1463
1464Fix fencepost error when clearing an the end of the block bitmap which
1465caused the last block in the bitmap not to get cleared.
1466
1467Cleaned up a number of messages in e2fsck:
1468 * The message "Group's #'s copy of the group descriptor..."
1469 was fixed so that the correct number would be displayed.
1470 * Added missing space in the "disk write-protected" error messsage
1471 * Cleaned up the error message printed when a non-interactive
1472 e2fsck needs to abort a check because the filesystem
1473 appears to be mounted.
1474
1475Added a new command-line utility, uuidgen, which will create and print
1476a UUID.
1477
1478Make debugfs's icheck command more robust by checking to make sure an
1479inode has valid blocks before interarting over the inode's blocks.
1480
1481UUID generation now uses a random-based scheme whenever possible to
1482prevent potential privacy problems.
1483
1484Man pages for all of the UUID functions in the lirbary were added.
1485
1486Fixed bug in fsck so it won't coredump if a filesystem not in
1487/etc/fstab is given to it.
1488
1489Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
1490that most of the other mount utilities understands.
1491
1492Mke2fs will make a filesystem even if it appears mounted if the force
1493option is given.
1494
1495Dumpe2fs has new command-line options which allow a filesystem expert
1496to specify the superblock and blocksize when opening a filesystem.
1497This is mainly useful when examining the remains of a toasted
1498filesystem.
1499
1500The badblocks program has been updated to display correctly on disks
1501with large block numbers.
1502
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001503The badblocks program no longer gives spurious errors when errors
1504occur on non-block boundaries, which is common if the blocksize is
1505larger than 1k.
1506
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001507Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
1508MKE2FS_SYNC environment variable is set. This is to work around a VM
1509bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001510to trigger it even using a 2.2 kernel, but hopefully it will not be
1511needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001512
1513Fixed miscellaneous documentation and man pages.
1514
1515Programmer's notes:
1516-------------------
1517
1518Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
1519in e2fsck's pass1.c really should have been static.
1520
1521The return value of the uuid_compare() function was changed to make it
1522match with the convetions used by strcmp, memcmp, and Paul Leach's
1523UUID sample document.
1524
1525The "make depend" process has now been made more automated; it now
1526automatically word-wraps the dependencies, and only replaces source
1527Makefile.in if there has been a change in the dependencies. Also, a
1528top-level "make depend" now recurses through all the subdirectories
1529automatically.
1530
1531The Makefile in .../util has been changed so that subst is built using
1532the native C compiler during a cross-compilation, since the subst
1533program is only used during the build process. Also add an explicit
1534rule to build util/subst by cd'ing to the correct directory and
1535running Makefile.
1536
1537The man directories are defined in terms mandir, so that the configure
1538script can override the location of the manual pages.
1539
1540The config files have been updated to recognize new machine types for
1541both the i386 and alpha families.
1542
1543Fsck has been modified so that it will accurately create an
1544fsck_instance even when the noexecute flag is set. This allows for
1545accurate debugging of the fsck pass structure. Also, when the verbose
1546flag is given twice, fsck will print debugging information about when
1547fsck is waiting for jobs to finish.
1548
1549
Theodore Ts'o14790ed1999-01-12 23:32:52 +00001550E2fsprogs 1.14 (January 9, 1999)
1551================================
1552
1553Fix the fstab parsing code so that it can handle blank lines and
1554comment characters. Also, missing pass numbers need to be treated as
1555zero.
1556
1557Fixed a bug in e2fsck where under some circumstances (when e2fsck
1558needs to restart processing after fixing an egregious inconsistency)
1559it would try to access already freed memory.
1560
1561E2fsck now prints non-printable characters in directory entries and
1562pathnames using '^' and 'M-' notation.
1563
1564Fixed chattr so that it will ignore symbolic links when doing
1565recursive descent traversals. For both chattr and lsattr, no longer
1566print the version string unless the -V option is given.
1567
1568Allow the system administrator to directly specify the number of
1569inodes desired in the filesystem, for some special cases where this is
1570necessary.
1571
1572Fix portability problems so that e2fsprogs can be compiled under Linux
15731.2 systems and Solaris systems.
1574
1575Update the config.guess file with a more recent version that will
1576identify newer Linux platforms.
1577
1578Programmer's notes
1579------------------
1580
1581Ext2fs_read_inode and ext2fs_write_inode will now return an error if
1582an inode number of zero is passed to them.
1583
Theodore Ts'o556ad131998-12-19 08:10:58 +00001584E2fsprogs 1.13 (December 15, 1998)
1585==================================
1586
1587Fixed a bug in debugfs where an error messages weren't getting printed
1588when the ext2 library routines to read inodes returned errors in the
1589stat, cmri and rm commands.
1590
1591Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
1592provided, it won't create an inode table smaller than the minimum
1593number of inodes required for a proper ext2 filesystem.
1594
1595Fsck now parses the /etc/fstab file directly (instead of using
1596getmntent()), so that it can distinguish between a missing pass number
1597field and pass number field of zero. This caused problems for
1598diskless workstations where all of the filesystems in /etc/fstab have
1599an explicit pass number of zero, and fsck could not distinguish this
1600from a /etc/fstab file with missing pass numbers.
1601
1602E2fsck will create a /lost+found directory if there isn't one in the
1603filesystem, since it's safer to create the lost+found directory before
1604it's needed.
1605
1606Fixed e2fsck so that it would detect bogus immutable inodes which
1607happen to be sockets and FIFO files, and offer to clear them.
1608
1609If a filesystem has multiple reasons why it needs to be checked, and
1610one of the reasons is that it is uncleanly mounted, e2fsck will print
1611that as the reason why the filesystem is being checked.
1612
1613Cleaned up the output routines of mke2fs so that it doesn't overflow
1614an 80 column display when formating really big filesystems.
1615
1616Added a sanity check to e2fsck to make sure that file descriptors 0,
16171, 2 are open before opening the hard disk. This avoids a problem
1618where a broken program might exec e2fsck with those file descriptors
1619closed, which would cause disastrous results if the kernel returns a
1620file descriptor for the block device which is also used by FILE *
1621stdout.
1622
1623Fixed up the e2fsck progress reporting functions so that the values
1624reliably reach 100% at the completion of all of the e2fsck passes.
1625
1626Fixed minor documentation bugs in man pages and usage messages.
1627
1628Programmer's notes:
1629-------------------
1630
1631Fixed a number of lint warnings in the ext2fs library and potential
1632portability problems from other OS's header files that might define
1633CPP macros for names like "max" and "min".
1634
1635ext2fs_badblocks_list_add() has been made more efficient when it needs
1636to grow the bad blocks list.
1637
1638Fixed a bug in e2fsck which caused it to dereference a freed pointer
1639just before exiting.
1640
1641Fixed the substition process for generating the mk_cmds and compile_et
1642scripts so that they will work outside of the build tree.
1643
1644Add sanity check to e2fsck so that if an internal routine
1645(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
1646and causing a core dump. This should never happen, but...
1647
Theodore Ts'oa5696711998-07-09 05:38:07 +00001648E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00001649==================================
1650
1651E2fsprogs now works with glibc (at least with the version shipped wtih
1652RedHat 5.0). The ext2fs_llseek() function should now work even with
1653i386 ELF shared libraries and if llseek() is not present. We also
1654explicitly do a configure test to see if (a) llseek is in libc, and
1655(b) if llseek is declared in the system header files. (See standard
1656complaints about libc developers don't understand the concept of
1657compatibility with previous versions of libc.)
1658
Theodore Ts'oc9833a61998-07-05 19:37:53 +00001659The ext2fs library now writes out the block group number in each of
1660the superblock copies. This makes it easier to automatically
1661determine the starting block group of the filesystem when the block
1662group information is trashed.
1663
1664Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00001665which means that e2fsprogs will ignore the high 8 bits of the
1666directory entry's name_len field, so that it can be used for other
1667purposes.
1668
1669Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
1670E2fsprogs will now support filesystems with 64-bit sized files.
1671
1672Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
1673
Theodore Ts'o21d53851998-02-21 03:14:50 +00001674Added new program "e2label", contributed by Andries Brouwer. E2label
1675provides an easy-to-use interface to modify the filesystem label.
1676
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00001677Fixed bug so that lsattr -v works instead of producing a core dump.
1678
Theodore Ts'o21d53851998-02-21 03:14:50 +00001679Fixed a minor bug in mke2fs so that all groups with bad superblock
1680backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00001681
1682Mke2fs will check the size of the device, and if the user specifies a
1683filesystem size larger than the apparent size of the device it will
1684print a warning message and ask if the user wants to proceed.
1685
Theodore Ts'oc9833a61998-07-05 19:37:53 +00001686E2fsck has a new option -C, which sends completion information to the
1687specified file descriptor. For the most part, this is intended for
1688programs to use, although -C 0 will print a spinning character to the
1689stdout device, which may be useful for users who want to see something
1690happening while e2fsck goes about its business.
1691
Theodore Ts'o21d53851998-02-21 03:14:50 +00001692Fixed a bug in e2fsck which could cause a core dump when it needs to
1693expand the /lost+found directory, and sometimes the bitmaps haven't
1694been merged in. Also fixed a related bug where ext2fs_write_dir_block
1695was used to write out a non-directory block. (Which would be bad on a
1696non-Intel platform with byte swapping going on.)
1697
1698Fixed bug in e2fsck where it would print a "programming error" message
1699instead of correctly identifying where a bad block was in used when
1700the bad block was in a non-primary superblock or block group
1701descriptor. Also fixed a related bug when sparse superblocks are in
1702use and there is a bad block where a superblock or block group
1703descriptor would have been in a group that doesn't include a
1704superblock.
1705
1706Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
1707the block group descriptor table is corrupt, it was possible to try to
1708allocate a huge array, fail, and then abort e2fsck.
1709ext2fs_get_num_dirs() now sanity checks the block group descriptor,
1710and subsitutes reasonable values if the descriptors are obviously bogus.
1711
1712If e2fsck finds a device file which has the immutable flag set and the
1713i_blocks beyond the normal device number are non-zero, e2fsck will
1714offer to remove it, since it's probably caused by garbage in the inode
1715table.
1716
1717When opening a filesystem, e2fsck specially checks for the EROFS error
1718code, and prints a specific error message to the user which is more
1719user friendly.
1720
1721If the filesystem revision is too high, change the e2fsck to print
1722that this is either because e2fsck is out of date, or because the
1723superblock is corrupt.
1724
1725E2fsck now checks for directories that have duplicate '.' and '..'
1726entries, and fixes this corruption.
1727
1728E2fsck no longer forces a sync of the filesystem (with attendant sleep
1729calls) at all times. The ext2fs_flush() function now performs a sync
1730only if it needed to write data blocks to disk.
1731
1732Fixed a minor bug in e2fsck's pass1b's file cloning function, where
1733certain errors would not be properly reported.
1734
1735Updated and expanded a few points in the man pages which users
1736complained wheren't explicit enough.
1737
1738Added special case byte-swapping code if compiling on the PowerPC, to
1739accomodate the strange big-endian variant of the ext2 filesystem that
1740was previously used on the PowerPC port.
1741
1742
1743Programmer's notes:
1744-------------------
1745
1746Removed C++ keywords from the ext2fs libraries so that it could be
1747compiled with C++.
1748
1749E2fsck's internal organization has now been massively reorganized so
1750that pass*.c don't have any printf statements. Instead, all problems
1751are reported through the fix_problem() abstraction interface. E2fsck
1752has also been revamped so that it can be called as a library from a
1753application.
1754
1755Added new fileio primitives in libext2fs for reading and writing
1756files on an unmounted ext2 filesystem. This interface is now used by
1757debugfs.
1758
1759Added a new libext2fs function for mapping logical block numbers of
1760a file to a physical block number.
1761
1762Added a new libext2fs function, ext2fs_alloc_block(), which allocates
1763a block, zeros it, and updates the filesystem accounting records
1764appropriately.
1765
1766Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
1767sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
1768
1769The libext2fs functions now use a set of memory allocation wrapper
1770functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
1771instead of malloc, free, and resize. This makes it easier for us to
1772be ported to strange environments where malloc, et. al. aren't
1773necessarily available.
1774
1775Change the libext2fs fucntion to return ext2-specific error codes
1776(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
1777and depending on the existence of system error codes (such as EEXIST
1778and ENOENT).
1779
1780Renamed io.h to ext2_io.h to avoid collision with other OS's header
1781files.
1782
1783Add protection against ext2_io.h and ext2fs.h being included multiple
1784times.
1785
1786The types used for memory lengths, etc. have been made more portable.
1787In generla, the code has been made 16-bit safe. Added Mark
1788Habersack's contributed DOS disk i/o routines.
1789
1790Miscellaneous portability fixes, including not depending on char's
1791being signed.
1792
1793The io_channel structure has a new element, app_data, which is
1794initialized by the ext2fs routines to contain a copy of the filesystem
1795handle.
1796
1797ext2fs_check_directory()'s callback function may now return the error
1798EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
1799really do the checking, despite the presence of the callback function.

Theodore Ts'obc210071997-06-17 05:41:36 +00001802E2fsprosg 1.11 (June 17, 1997)
1803==============================
1804
1805Fixed e2fsck to detect (previously ignored) conflicts between the
1806superblock or block group descriptors and block bitmaps, inode
1807bitmaps, and inode tables.
1808
1809Fixed bug in e2fsck so that when the message printed out when a block
1810or inode bitmap conflicts with other data, it has the correct group
1811number.
1812
1813Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
1814to badblocks. This meant that not all of the filesystem was being
1815tested for bad blocks!
1816
1817Fixed an array boundary overrun case which cropped up in
1818ext2fs_badblocks_list_test when a user tried running "mke2fs -c
1819-b 4096".
1820
1821Adjusted the number of columns printed by mke2fs when displaying the
1822superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00001823really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00001824
1825Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
1826dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
1827fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
1828
1829Programmer's notes:
1830-------------------
1831
1832Fixed install rule in lib/ss so that ss_err.h is actually getting
1833installed.
1834
1835Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
1836bassed back to the caller.
1837
1838Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
1839setting the current inode number (which meant this function wasn't
1840working at all).
1841
1842Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
1843blocks in the bitmap when increasing the size of the bitmap.
1844
1845Changed the initial number of blocks allocated by ext2fs_init_dblist()
1846to be more realistic.
1847
1848Added a new function ext2fs_allocate_group_table, which sets up the
1849group descriptor information (and allocates inode and block bitmaps,
1850and inode tables for a particular group). The function was created by
1851factoring out code form ext2fs_allocate_tables().
1852
1853Added a new function ext2fs_move_blocks which takes a bitmap of the
1854blocks to be moved, and moves them to another location on the
1855boardboard.
1856
1857Make the unix_io channel's io_channel_flush implementation calls sync()
1858to to flush the kernel buffers to disk.
1859
1860Added a new function ext2fs_dblist_count returns the number of
1861directory blocks in dblist.
1862
1863
Theodore Ts'oae851481997-04-29 18:13:24 +00001864E2fsprogs 1.10 (April 24, 1997)
1865===============================
1866
1867Mke2fs once again defaults to creating revision #0 filesystems, since
1868people were complaining about breaking compatibility with 1.2 kernels.
1869Warning messages were added to the mke2fs and tune2fs man pages that
1870the sparse superblock option isn't supported by most kernels yet (1.2
1871and 2.0 both don't support parse superblocks.)
1872
1873Added new flag to mke2fs, -R <raid options>, which allows the user to
1874tell mke2fs about the RAID configuration of the filesystem. Currently
1875the only supported raid option is "stride" which specifies the width
1876of the RAID stripe.
1877
1878Fixed bug in e2fsck where pass1b would bomb out if there were any
1879blocks marked bad in the inode table.
1880
1881Fixed rare bug in mke2fs where if the user had a very unlucky number
1882of blocks in a filesystem (probability less than .002) the resulting
1883filesystem would be corrupt in the last block group.
1884
1885Fixed bug where if e2fsck tried to allocate a block to fix a
1886filesystem corruption problem and the filesystem had no free blocks,
1887ext2fs_new_block() would loop forever.
1888
1889The configure script now checks explicitly to see if "-static" works,
1890since that can't be assumed to be true --- RedHat doesn't install
1891libc-static by default.
1892
1893Fixed bug in libext2's block iterator functions where under some
1894cirmcustances, file with holes would cause the bcount parameter to the
1895callback function to be incorrect. This bug didn't affect any of
1896e2fsprogs programs, but it was discovered by Paul Mackerras, the
1897author of the PPC boot loader.
1898
1899Removed use of static variables to store the inode cache in libext2fs.
1900This caused problems if more than one filesystem was accessed via
1901libext2fs (static variables in libraries are generally a bad idea).
1902Again, this didn't affect e2fsprogs programs, but it was discovered by
1903Paul Mackerras.
1904
1905Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
1906will compile cleanly with 1.2.13 kernels (even with a.out shared
1907libraries!)
1908
1909Programmer's notes:
1910-------------------
1911
1912Added new functions to duplicate an ext2 filesystem handle, and its
1913associated substructure. New functions: ext2fs_dup_handle(),
1914ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
1915Other structures, such as the io_channel and the inode_cache, now have
1916a ref count so that they only get freed when they are no longer used
1917by any filesystem handle. (These functions were added as part of the
1918development effort for an ext2 resizer).
1919
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00001920E2fsprogs 1.09 (April 14, 1997)
1921===============================
1922
1923Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
1924accidentally introduced in the 1.08 release. The overhead calculation
1925was accidentally removed, which caused ext2fs_initialize() to not
1926notice when the filesystem size needed to be adjusted down because
1927there wasn't enough space in the last block group.
1928
1929Fixed bug in version parsing library routine; it was always parsing
1930the library version string, instead of using the passed-in string.
1931
1932Clarified chattr man page.
1933
Theodore Ts'o24757fa1997-04-29 17:39:27 +00001934E2fsprogs 1.08 (April 10, 1997)
1935===============================
1936
1937E2fsck 1.07 was very slow when checking very large filesystems with a
1938lot of files that had hard links (i.e., news spools). This was fixed
1939by seriously revamping the icount abstraction. Added a formal test
1940suite for the icount abstraction.
1941
1942Debugfs now has a "-l" option to the "ls" command, which lists the
1943inode number, permissions, owner, group, size, and name of the files
1944in the directory.
1945
1946Fix a bug in e2fsck where when a directory had its blocks moved to
1947another location during the pass 1b processing, the directory block
1948list wasn't updated, so pass 2 wouldn't check (and correct) the
1949correct directory block.
1950
1951E2fsck will now treat inodes which contain blocks which are claimed by
1952the filesystem metadata by treating them as multiply claimed blocks.
1953This way, the data in those blocks can be copied to a new block during
1954the pass 1b--1d processing.
1955
1956E2fsck will attempt to determine the correct superblock number and
1957display it in the diagnostic and warning messages if possible.
1958
1959Add support for a new (incompatible) feature, "sparse_super". This
1960feature reduces the number of blocks which contain copies of backup
1961superblocks and block group descriptors. (It is only an incompatible
1962feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
1963support a new -s option; e2fsck will recognize filesystems built with
1964this feature turned on.
1965
1966E2fsck now checks the library to make sure is the correct version,
1967using new library functions. (This helps to diagnose incorrectly
1968installed e2fsprogs distributions.)
1969
1970Dumpe2fs now prints more information; its now prints the the
1971filesystem revision number, the filesystem sparse_super feature (if
1972present), the block ranges for each block group, and the offset from
1973the beginning of the block group.
1974
1975Mke2fs now distributes the inode and block bitmap blok so that the
1976won't be concentrated in one or two disks in RAID/striping setups.
1977Also, if the user chooses a 2k or 4k block group, mke2fs will try to
1978choose the largest blocks per group that be chosen. (For 2k blocks,
1979you can have up to 16384 blocks/group; for 4k blocks, you can have up
1980to 32768 blocks/group.) Previously mke2fs would not allow
1981specification of more than 8192 blocks per group, even if you were
1982using a 2k or 4k block group.
1983
1984Programmer's notes:
1985-------------------
1986
1987Added a new function ext2fs_create_icount2() which takes a "hint"
1988argument. This hint argument presets the icount array with the list
1989of inodes which actually need to be in the icount array. This really
1990helps to speed up e2fsck.
1991
1992Added a new function ext2fs_icount_validate() which checks the rep
1993invariant for the icount structure. This is used mostly for testing.
1994
1995The error mesasage given when a bad inode number is passed to
1996test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
1997EXT2FS_UNMARK_ERROR).
1998
1999Added a new function ext2fs_set_dir_block which sets the block of a
2000dblist entry, given the directory inode and blockcnt.
2001
2002Added a new function ext2fs_get_library_version() which returns the
2003current library version, and ext2fs_parse_version_string() which
2004returns a version number based on a e2fsprogs version string.
2005
2006The icount functions will return EINVAL if the passed in inode number
2007is out of bounds.
2008
Theodore Ts'o21c84b71997-04-29 16:15:03 +00002009E2fsprogs 1.07 (March 9, 1997)
2010==============================
2011
2012E2fsck is now uses much less memory when checking really large
2013filesystems (or rather, filesystems with a large number of inodes).
2014Previously a filesystem with 1 million inodes required 4 megabytes of
2015memory to store inode count statistics; that storage requirement has
2016now been reduced to roughly half a megabyte.
2017
2018E2fsck can now properly deal with bad blocks appearing inside the
2019inode table. Instead of trying to relocate the inode table (which
2020often failed because there wasn't enough space), the inodes in the bad
2021block are marked as in use.
2022
2023E2fsck will automatically try to use the backup superblocks if the
2024primary superblocks have a bad magic number or have missing meta-data
2025blocks (or meta-data blocks which are out of range).
2026
2027E2fsck's pass 3 has been made more efficient; most noticeable on
2028filesystems with a very large number of directories.
2029
2030Completely revamped e2fsck's system of printing problem reports. It
2031is now table driven, to make them more easily customizeable and
2032extendable. Error messages which can be printed out during preen mode
2033are now one line long.
2034
2035Fixed e2fsck's filesystem swapping code so that it won't try to swap
2036fast symbolic links or deleted files.
2037
2038Fixed e2fsck core dumping when fixing a filesystem which has no
2039directories (not even a root directory).
2040
2041Added a check to e2fsck to make sure that the length of every
2042directory entry is a multiple of 4 (since the kernel complains if it
2043isn't).
2044
2045Added a check to e2fsck to make sure that a directory entry isn't a
2046link to the root directory, since that isn't allowed.
2047
2048Added a check to e2fsk to now make sure the '.' and '..' directory
2049entries are null terminated, since the 2.0 kernel requires it.
2050
2051Added check to write_bitmaps() to make sure the superblock doesn't get
2052trashed if the inode or block bitmap is marked as being block zero.
2053
2054Added checking of the new feature set fields in the superblock, to
2055avoid dealing with new filesystem features that this package wasn't
2056set up to handle.
2057
2058Fixed a fencepost error in ext2fs_new_block() which would occasionally
2059try to allocate a block beyond the end of a filesystem.
2060
2061When the UUID library picks a random IEEE 802 address (because it
2062can't find one from a network card), it sets the multicast bit, to
2063avoid conflicting with a legitimate IEEE 802 address.
2064
2065Mke2fs now sets the root directory's owner to be the real uid of the
2066user running mke2fs. If the real uid is non-zero, it also sets
2067the group ownership of the root directory to be the real group-id of
2068the user running mke2fs.
2069
2070Mke2fs now has more intelligent error checking when it is given a
2071non-existent device.
2072
2073When badblocks is given the -vv option, it now updates the block that
2074it is currently testing on every block.
2075
2076Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
2077currently correctly if PATH wasn't already set.
2078
2079Shared libraries now built with dependencies. This allows the shared
2080library files to be used with dlopen(); it also makes the transition
2081to libc 6 easier, since ld.so can tell which libc a particular shared
2082library expects to use.
2083
2084Programmer's notes:
2085-------------------
2086
2087Added new abstraction (defined in dblist.c) for maintaining a list of
2088blocks which belongs to directories. This is used in e2fsck and other
2089programs which need to iterate over all directories.
2090
2091Added new functions which test to see if a contiguous range of blocks
2092(or inodes) are available. (ext2fs_*_bitmap_range).
2093
2094Added new function (ext2_inode_has_valid_blocks) which returns true if
2095an inode has valid blocks. (moved from e2fsck code).
2096
2097Added new function (ext2fs_allocate_tables) which allocates the
2098meta-data blocks as part of initializing a filesystem. (moved from
2099mke2fs code).
2100
2101Added a new I/O manager for testing purposes. It will either allow a
2102program to intercept I/O requests, or print debugging messages to
2103trace the activity of a program using the I/O manager.
2104
2105The badblocks_list functions now store the bad blocks in a sorted
2106order, and use a binary search to speed up badblocks_list_test.
2107
2108The inode scan function ext2fs_get_next_inode() may now return a soft
2109error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
2110those cases where part of an inode table is missing or there is a bad
2111block in the inode table.
2112
2113Added a new function (ext2fs_block_iterate2) which adds new arguments to
2114the callback function to return a pointer (block and offset) to the
2115reference of the block.
2116
2117Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
2118application to jump to a particular block group while doing an inode
2119scan.
2120
2121The badblocks list functions were renamed from badblocks_* to
2122ext2fs_badblocks_*. Backwards compatibility functions are available
2123for now, but programs should be modified to use the new interface.
2124
2125Some of the library functions were reorganized into separate files to
2126reduce the size of some programs which statically link against the
2127ext2 library.
2128
2129Put in some miscellaneous fixes for the Alpha platform.
2130
Theodore Ts'o5c576471997-04-29 15:29:49 +00002131
2132E2fsprogs 1.06 (October 7, 1996)
2133================================
2134
2135Fixed serious bug in e2fsck: if the block descriptors are bad, don't
2136smash the backup copies in ext2fs_close(). (The problem was that when
2137e2fsck -p discovered the problem, while it was closing the filesystem
2138and exiting, it was also blowing away the backup superblocks on the
2139disk, which was less than friendly.) We now make it the case that we
2140only write out the backup superblock and the back block descriptors if
2141the filesystem is completely free from problems.
2142
2143Fixed a bug in block_interate in the lib/ext2fs library which caused
2144e2fsck to fail on GNU Hurd-created filesystems.
2145
2146Add support for Linux/FT's bootloader, which actually uses
2147EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
2148to clear the inode.
2149
2150Add support for the "A" (no atime update) attribute. (Note: this
2151attribute is not yet in production kernels.)
2152
2153The test suite is not automatically run when doing a "make all" from
2154the top level directory. Users should manually run "make check" if
2155they wish to run the test suite.
2156
2157Upon a preenhalt(), make the printed message more explicit that
2158running e2fsck "MANAULLY" means without the -p or -a options.
2159
2160In e2fsck, if a disconnected inode is zero-length, offer to clear it
2161instead of offering to connect it to lost+found.
2162
2163In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2164e2fsck to be run over it, change e2fsck to explicitly display this
2165fact.
2166
2167For dumpe2fs and e2fsck, cause the -V option to print out which
2168version of the ext2fs library is actually getting used. (This will
2169help detect mismatches of using a 1.06 utility with a 1.05 library,
2170etc.)
2171
2172Programmers' notes:
2173-------------------
2174
2175EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2176the naming convention.
2177
2178In ext2fs_initialize(), make sure the description for the inode bitmap
2179is correctly initialize.
2180
2181Fixed minor type typo in ext2fs_allocate_generic_bitmap();
2182
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002183E2fsprogs 1.05 (September 7, 1996)
2184==================================
2185
2186Add support for new fields in the ext2 superblock --- volume name,
2187volume UUID, and last mounted field. Dumpe2fs displays these fields,
2188tune2fs and mke2fs allows you to set them. E2fsck will automatically
2189generate a UUID for those volumes that don't have them.
2190
2191Put in support for e2fsck to recognize HURD specific ext2 features ---
2192most notably, the translator block. The e2fsprogs tools will now use
2193the creator_os field in the superblock to correctly handle different
2194OS-specific variants of the ext2 filesystem.
2195
2196E2fsck now fixes inodes which have a the deletion time set, but which
2197have a non-zero i_link_count field by offering to clear the deletion
2198time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2199ext2 kernel behavior) and offered to unlink the file.
2200
2201If e2fsck sets the clean bit, but nothing else, set the exit code
2202FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2203set the filesystem valid bit when it was previously cleared. :-) This
2204was needed to make the HURD fsck driver happy.
2205
2206If the user refuses to attach an unattached inode, e2fsck will no
2207longer set the inode's link count. Otherwise, the inode would end up
2208getting marked as unused, which might cause loss of data later.
2209
2210Make the message issued by e2fsck when the superblock is corrupt less
2211confusing for users. It now mentions that another reason for the
2212"corrupt superblock" message might be that the partition might not be
2213an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2214
2215Make the libext2 library more robuest so that e2fsck won't coredump on
2216an illegal superblock where the blocksize is zero. (f_crashdisk is
2217the test case).
2218
2219By default, create filesystems where the default checkinterval is 6
2220months (180 days). Linux servers can be robust enough that 20 reboots
2221can be a long, long time.
2222
2223Added configure flag --enable-old-bitops, which forces the bitops to
2224use the old (native) bitmask operations. By default on the sparc
2225platform, the standard ext2 bit ordering is now used.
2226
2227Added a new feature to e2fsck to byte-swap filesystems; this can be
2228used to convert old m68k filesystems to use the standard byte-order
2229storage for the superblock, inodes, and directory blocks. This
2230function is invoked by using the '-s' option to e2fsck.
2231
2232Debugfs's "dump" command has been enhanced so that it writes out the
2233exact size of the file so that the nulls at the end of the file are
2234eliminated. The command also accept a new "-p" option which will
2235attempt preserve to preserve the ownernship, permissions, and
2236file modification/access times.
2237
2238Debugfs has two new options, -f and -R. The -R option allows the user
2239to execute a single debugfs command from the command line. The -f
2240option allows the user to specify a "command file" containing debugfs
2241commands which will get executed.
2242
2243Dumpe2fs now pretty prints the check interval, instead of just
2244printing the check interval as a number of seconds.
2245
2246Fix bugs in debugfs: the params command when no filesystem is opened
2247no longer causes a core dump. It is now possible to unlink a file
2248when a pathame containing a '/' is specified.
2249
2250Tune2fs has a new -C option which sets the number of times the
2251filesystem has been mounted.
2252
2253Fix the chattr '-v' option so that it actually works. Chattr was
2254being buggy about the -v option parsing.
2255
2256Programmers' notes:
2257-------------------
2258
2259The directory lib/uuid contains a set of library routines to generate
2260DCE compatible UUIDs.
2261
2262Extended ext2fs_namei() to handle symbolic links. Added new function
2263ext2fs_nami_follow() which will follow last symbolic link in the case
2264where the pathname points to a sym link.
2265
2266The ext2fs_block_iterate function will now return the HURD translator
2267block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2268iterator to return data blocks only. The ext2fs.h file now defines
2269constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2270BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2271count field of the iterator callback function.
2272
2273The test script driver now takes an optional second argument, which is
2274the test case to be run. This allows you to run a test case without
2275needing to run the entire test suite.
2276
2277On Linux ELF systems, install the .so files in the correct places
2278(/usr/lib). The .so files must be stored in the same directory as the
2279.a files.
2280
2281Fixed miscellaneous HURD compilation issues with header file being
2282included in the right order.
2283
2284Fixed debugfs so that it resets optind to zero, not one, since setting
2285optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +00002288E2fsprogs 1.04 (May 16, 1996)
2289=============================
2290
2291First "official" (1.03 was a limited release only) to support building
2292e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2293kernels).
2294
2295This package includes a RPM specs file, that it can be built using the
2296RedHat Package Manager.
2297
2298E2fsck now prints a hint that if there are lots of incorrectly located
2299inode bitmaps, block bitmaps, and inode table blocks, the user might
2300want to try using e2fsck -b 8193 first, to see if that fares any
2301better.
2302
2303For ext2 filesystem written with the hurd, debugfs will now print out
2304the translator field when printing an inode structure.
2305
2306Lots of miscellaneous linking/installation cleanups:
2307
2308 Libraries are now linked using a relative pathname, instead of
2309 relying on -L working correct. It doesn't, in many cases, including
2310 current versions of GNU ld. This guarantees that the build tree is
2311 linking with the right libraries, instead of the ones installed in
2312 /usr/lib.
2313
2314 Header files, man pages, and the et/ss shell scripts are now
2315 generated using a custom substitution script, instead of relying on
2316 the configure script. This prevents needless recompilation of
2317 files; in addition, the custom substitution script is much faster.
2318
2319 e2fsck may now be linked dynamically, by using the
2320 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2321 since it increases e2fsck's dependence on other files, but some
2322 people need to save disk space, and other critical programs on their
2323 systems were being linked dynamically anyway.
2324
2325 Programs such as fsck which didn't need to be linked against
2326 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2327 only link against libraries they actually need. Otherwise, those
2328 programs would require the presense of libraries that otherwise
2329 could be removed from a rescuse diskette.
2330
2331 The ss include files are now installed correctly so they can
2332 actually be used by another package.
2333
2334 If the profiling libraries are built, they are now installed on a
2335 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00002338E2fsprogs 1.03 (March 27, 1996)
2339===============================
2340
2341Change the m68k bit numbering for bitmasks to match the bit numbering
2342used by all other ext2 implementations. (This change was requested by
2343the m68k kernel development team.)
2344
2345Support (in-development) filesystem format revision which supports
2346(among other things) dynamically sized inodes.
2347
2348Fixed a bug in the ext2 library so that an intelligent error is
2349returned if mke2fs is run with a ridiculously small number of blocks
2350for a partition.
2351
2352Fixed a bug in the ext2 library which required that the device be
2353openable in read/write mode in order to determine its size. This
2354caused e2fsck -n to require read/write access when it was not
2355previously necessary.
2356
2357Fixed a bug in e2fsck which casued it to occasionally fail the test
2358suite depending on which version of the floating point library it was
2359using.
2360
2361Fixed a bug in e2fsck so that it now halts with a fatal error when
2362certain superblock consistency checks fail. Previously it continued
2363running e2fsck, with some potential confusing/damaging consequences.
2364
2365Added new flag to fsck which allows the root to be checked in parallel
2366with other filesytems. This is not the safest thing in the world to
2367do, but some system administrators really wanted it.
2368
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002369Fixed -Wall flames in lib/ss.
2370
Theodore Ts'o74becf31997-04-26 14:37:06 +00002371
2372E2fsprogs 1.02 (January 16, 1996)
2373=================================
2374
2375Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
2376
2377Change e2fsck to print statistics of how many non-contiguous files are
2378on the system. Note that a file which is larger than 8k blocks, it is
2379guaranteed to be non-contiguous.
2380
2381In mke2fs, print a warning message if a user tries to format a whole
2382disk (/dev/hda versus /dev/hda1). If a user really wants to format a
2383whole disk, the -F (force) option forces mke2fs to format a whole disk
2384as a filesytem.
2385
2386Fix a bug in fsck where in some cases it might start checking
2387partitions in the next pass before it finishes checking partitions in
2388the current pass. This still won't cause two partitions on the same
2389disk will be checked, so it's rarely a problem in real life.
2390
2391Patch lsattr so that it won't hang when checking a named pipe.
2392
2393Minor compilation fixes:
2394 * Fix the order of libraries that were linked in debugfs.
2395 * Allow the sources to be compiled with -ansi turned on.
