Theodore Ts'oedde3e52009-08-22 22:38:50 -04001E2fsprogs 1.41.9 (August 22, 2009)
2==================================
3
4Fix a bug in e2fsck routines for reallocating an inode table which
5could cause it to loop forever on an ext4 filesystem with the FLEX_BG
6filesystem feature with a relatively rare (and specific) filesystem
7corruption. This fix causes e2fsck to try to find space for a new
8portion of the inode table in the containing flex_bg, and if that
9fails, the new portion of the inode table will be allocated in any
10free space available in the filesystem.
11
12Make e2fsck less annoying by only asking for permission to relocate a
13block group's inode table once, instead of for every overlapping
14block. Similarly, only ask once to recompute the block group
15checksums, instead of once for each corrupted block group's checksum.
16
17Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
18not present, and it needs to fall back to using the FIBMAP ioctl.
19
20Fix filefrag to correctly print the number of extents for zero-length
21files. (Addresses Debian Bug: #540376)
22
23Filefrag now has a -B option which forces the use of the FIBMAP ioctl
24to more easily debug the FIBMAP code.
25
26Fixed filefrag for non-extent based files.
27
28Add a new program, e2freefrag, which displays information about the
29free space fragmentation in an ext2/3/4 filesystem.
30
31Fix inode resizing via tune2fs -I so that it works correctly in the
32face of non-empty bad blocks inodes, and if the filesystem was
33formatted using the "mke2fs -E stride=N" option for RAID arrays.
Theodore Ts'o776a3742009-07-20 09:40:46 -040034
35Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
36and corrupt large directories if the directory needs to shrink by more
37than one block. (Addresses Debian Bug: #537510)
38
39Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
40last mount times are in the future, they are corrected even if
41buggy_init_scripts is set. This is needed because otherwise resize2fs
42will refuse to resize the filesystem, even after running "e2fsck -f".
43(Addresses Launchpad bug: #373409)
Theodore Ts'oedde3e52009-08-22 22:38:50 -040044
45E2fsck will now print much fuller information when the last mount time
46or last written time is in the future, since most people can't seem to
47believe their distribution has buggy init scripts, or they have a
48failed CMOS/RTS clock battery.
49
50Enhance dumpe2fs to dump the extent information via the 'stat'
51command, and more detailed extent information via the new command
52'dump_extents'.
Theodore Ts'o776a3742009-07-20 09:40:46 -040053
Theodore Ts'oedde3e52009-08-22 22:38:50 -040054Update French, Polish, Czech, and Sweedish translation from the
55Translation Project.
Theodore Ts'o776a3742009-07-20 09:40:46 -040056
57Fixed various Debian packaging issues --- see debian/changelog for
58details.

60Programmer's Notes
61------------------
62
63Fixed miscellaneous gcc -Wall warnings.
64
65Fixed memory leak in error path in ext2fs_block_iterate2()
66
67Fixed non-Linux build of the intl directory by adding support for the
68E/Q/V macros.
69
Theodore Ts'oedde3e52009-08-22 22:38:50 -040070The bitmap read/write functions now treat uninitialized bitmaps as
71unallocated; this fixes a number of problems in all e2fsprogs for ext4
72filesystems when there is a need to allocate new blocks or inodes, and
73there aren't any free blocks or inodes in the already-used block
74groups.
75
Theodore Ts'o776a3742009-07-20 09:40:46 -040076Improve ext2fs_extent_set_bmap() to avoid creating new extents which
77get inserted into the extent tree when they are not needed.

Theodore Ts'oc179bca2009-07-11 19:21:43 -040080E2fsprogs 1.41.8 (July 11, 2009)
81================================
Theodore Ts'o24a24cc2009-07-09 08:09:58 -040082
83Fix resize2fs's online resizing, fixing a regression which in
84e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
85
86Fix potential filesystem corruptions caused by using resize2fs to
Theodore Ts'o989a01f2009-07-11 18:29:56 -040087shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
88Bug: #510379)
Theodore Ts'o24a24cc2009-07-09 08:09:58 -040089
90Optimize uuid_generate() to avoid running uuidd if it is not setuid or
91setgid and the currently running program doesn't have write access to
92the uuidd work directory.
93
94Add safety checks (for non-Linux systems) so that uuidd isn't run with
95file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
96will be careful not to close the file descriptor for its unix domain
97socket when it detaches itself from the controlling tty. Also add
98safety checks so that if the unix domain socket between the uuid
99library and uuidd program is closed for any reason, both the library
100and the uuidd will return an appropriate error code instead of looping
101in an infinite loop.
102
103The e2croncheck script, which creates an LVM snapshot and then checks
104the ext3/4 filesystem via the LVM snapshot, has been added to the
105contrib directory.
106
107Fix filefrag program for files that have more than 144 extents.
108
Theodore Ts'o989a01f2009-07-11 18:29:56 -0400109Update French, Polish, Czech, Indonsian, and Sweedish translation from
110the Translation Project.
111
112Fixed various Debian packaging issues --- see debian/changelog for
113details. (Addresses Debian Bug #535530)
Theodore Ts'o24a24cc2009-07-09 08:09:58 -0400114
115Update/clarify man pages.
116
117Programmer's Notes
118------------------
119
120Fix compilation problem when configured with --disable-uuid.
121
122Don't build uuidgen if configured with --disable-uuid.
123
Theodore Ts'o989a01f2009-07-11 18:29:56 -0400124Add the new library function ext2fs_test_inode_bitmap_range(), and
125optimized ext2fs_test_block_bitmap_range(), which will be needed for
126future optimizations for e2fsck.
127
Theodore Ts'o24a24cc2009-07-09 08:09:58 -0400128Fix makefile dependencies for libcom_err so that the Makefiles work
129well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
130
131Enhance the build system so that the full set of commands executed by
132the Makefiles are displayed, instead of the Linux kernel summary
133output, if the build was configured with --enable-verbose-makecmds, or
134if GNU make is in use and the V variable is non-null, i.e., via "make
135V=1".

Theodore Ts'od9206a32009-06-29 12:56:04 -0400138E2fsprogs 1.41.7 (June 29, 2009)
139================================
140
141Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
142uninitalized data into the portion of the inode beyond the first 128
143bytes when operating on inodes mapped via extents; potentially
144corrupting filesystems.
145
146Fix memory leaks in e2fsprogs, including a very large memory leak
147which can cause e2fsck to run out of memory when checking very large
148filesystems using extents.
149
150The logsave program will now filter out the ^A and ^B characters when
151writing to the console.
152
153Harden ext2fs_validate_entry() so that lsdel will not read beyond the
154end of the block even if the directory block is corrupted.
155
156Fix debugfs from core dumping if the logdump command fails to open the
157output file.
158
159Enhance badblocks to print the currently tested block number when
160interrupted with ^C.
161
162Fix lsattr to exit with a non-zero status when it encounters errors.
163(Addresses RedHat Bugzilla #489841)
164
165Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
166filesystems as the kernel when encoding rec_len >= 64k. For 64k
167filesystems (currently all that is supported by e2fsprogs, this is
168only a minor corner case).
169
170Resize2fs will now update the journal backup fileds in the sup0erblock
171if the journal is moved; this avoids an unnecessary full fsck after
172resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
173
174Fix libext2fs to properly initialize i_extra_size when creating the
175journal and resize inodes.
176
177Change badblocks to allow block sizes larger than 4k.
178
179Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
180
181Update Chinese and Czech translation from the Translation Project.
182
183Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
184
185
186Programmer's Notes
187------------------
188
189Add --disable-libuuid option to configure which uses an in-system
190installed version of libuuid; the private version is enabled by
191default.
192
193Add --valgrind-leakcheck option to the test_script program which runs
194valgrind with the appropriate options to find memory leaks.

Theodore Ts'od17ad122009-05-30 13:56:31 -0400197E2fsprogs 1.41.6 (May 30, 2009)
198===============================
199
200Fix a critical regression in e2fsck introduced version 1.41.5 which
201can undo updates to the block group descriptors after a journal replay.
202
203If e2fsck receives an I/O error while replaying the journal, prompt
204the user whether they want to ignore the error or not; if e2fsck is
205run in preen mode, force fsck to abort the preen pass.
206
207Fix a bug which would cause e2fsck to core dump if the filesystem
208contains a corrupt extent header, and the user declines to clear the
209inode. (Addresses Sourceforge Bug: #2791794)
210
211Fix e2fsck to restart only once in the case of multiple block groups
212which inodes in use that are in the uninitialized part of the block
213group's inode table.
214
215To reduce user confusion, if the /etc/mtab file is missing
216ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
217new, explicit error code to indicate this case. This will cause
218e2fsck to give a clearer error message when the user is using buggy
219rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
220Bug: #527859)
221
222Fix e2fsck so that if the primary group descriptors are corrupted, but
223the backup superblock is entirely invalid, to go back to using (and
224fixing) the priary group descriptors instead of completely giving up
225on the filesystem. (Addresses Debian Bug: #516820)
226
227Change e2fsck to not abort a preen pass if an inode is found to have
228i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
229kernels (post 2.6.29) will ignore this field. So let's fix it
230automatically during the preen pass instead of forcing the user to fix
231this up manually. (Addresses Debian Bug: #526524)
232
233Add resource tracking for e2fsck passes 1b through 1d.
234
235Speed up e2fsck by eliminating unnecessary journal checks if the
236filesystem is already mounted and doesn't need recovery (since the
237kernel would have run the journal when the filesystem was mounted.)
238Also speed up e2fsck by avoiding unnecessary block group descriptor
239updates in ext2fs_close().
240
241Add support to chattr to migrate inodes from using direct/indirect
242blocks to extents.
243
244Avoid corrupting the filesystem if there is an attempt to shrink a
245filesystem using resize2fs smaller than posible by making
246ext2fs_set_bmap() more careful not to delete the old block until the
247new block can be inserted. In addition, fix a bug in how the minimum
248size of the filesystem (plus a safety margin) is calculated, and
249modify resize2fs to refuse to shrink the filesystem below that minimum
250size without the force flag.
251
252Teach blkid to try to figure out DM device names using take advantage
253of information in sysfs when running on kernels (2.6.29 and later)
254which provide this information in /sys/block/dm-<N>/dm/name; this is
255much faster than scanning for the devncie number in /dev/mapper.
256
257Fix blkid to prefer /dev/mapper/<name> device names instad of the
258private /dev/dm-X names.
259
260Add an -a option to debugfs's close_filesys command which writes any
261changes to the superblock or block group descriptors to all of the
262backup superblock locations.
263
264Add support to the filefrag program to use the FIEMAP ioctl.
265
266Update Chinese translation from the Translation Project.
267
268Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
269Launchpad Bug: #381854)
270
271Fixed various Debian packaging issues --- see debian/changelog for
272details. (Addresses Debian Bug #506064)
273
274
275Programmer's Notes
276------------------
277
278Add test code to make sure e2fsck's problem.c doesn't have two problem
279codes assigned to duplicate values.
280
281Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
282(Addresses Sourceforge Bug: #2780205)
283
284Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
285function declaration for init_resource_track() and
286print_resource_track() when RESOURCE_TRACK is not defined.
287
288The test code which is used to build the tst_csum progam has been
289moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
290avoid compile problems caused by not having a prototype for
291ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
292
293Update the config.guess and config.sub file to the latest from the
294FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
295Debian Bug: #528330)
296
297Add a new function, ext2fs_extent_open2(), which behaves like
298pext2fs_extent_open(), but uses the user-supplied inode structure
299when opening an extent instead of reading the inode from disk.
300

Theodore Ts'o898ddb02009-04-23 22:44:16 -0400302E2fsprogs 1.41.5 (April 23, 2009)
303=================================
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400304
305Fix a number of filesystem corruption bugs in resize2fs when growing
306or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
307is not mounted).
308
309Debugfs can now set i_file_acl_high via the set_inodes_field command,
310and print a 64-bit file acl. This is useful for debugging filesystem
Theodore Ts'o898ddb02009-04-23 22:44:16 -0400311corruptions where the high bits of i_file_acl_high are set. E2fsck
312will detect and fix non-zero i_file_acl_high on 32-bit filesystems
313since some Linux kernel versions pay attention to this field even when
314they shouldn't.
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400315
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400316Speed up e2fsck when checking clean filesystems by avoiding
317unnecessary block reads, and coalescing the block group descriptor
318blocks so they are read using a single read operation.
319
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400320The libuuid library will now close all file descriptors before running
321uuidd. This avoids problems when the calling program has open sockets
322which then never get closed because uuidd is a long-running helper
323daeomn. (Addresses Launchpad bug: #305057)
324
325In order to avoid unnecessary full filesystem checks by e2fsck after
326an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
327the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
328
329Mke2fs will avoid trying to create the journal when run in
330superblock-only mode (mke2fs -S), since the left-over journal in the
331inode table will cause mke2fs to fail.
332
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400333Fix a bug in libext2fs functions that check to see if a particular
334device or filesystem image is mounted, which would cause these
335functions to report that a file identical to the (relative) pathname
336used by a pseudo-filesystem was mounted when in fact it was not.
337
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400338Update Czech translation from the Translation Project.
339
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400340Add Chinese (simplified) translation from the Translation Project.
341
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400342Fix support for external journals (which was broken in e2fsprogs
3431.41.4).
344
345Fix a regression in debugfs where the "stat" command when no
346filesystem was open would cause debugfs to crash with a segmentation
347violation.
348
349Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
350used to support filesystems without a journal. Update the blkid
351library so it understands this.
352
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400353The blkid library will remove an entry from the blkid cache
354representing the entire disk if partitions are found, since presuambly
355the device previously had no partition table, but has now transitioned
356to using a partition table.
357
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400358Add a check to mke2fs and tune2fs that the argument to the -m option
359(which specifies the reserved ratio) must be greater than zero.
360(Addresses Debian Bug: #517015)
361
362Add support for tracking the number kilobytes written to the
363filesystem via the superblock field s_kbytes_written. It will be
364updated by the kernel as well as by e2fsprogs programs which write to
365the filesystem. This is useful for tracking the wear to filesystems
366on Solid Sstate Drives.
367
368Fix compatibility issue in the libext2fs info file and makeinfo
369version 4.12. (Addresses Red Hat Bugzilla: #481620)
370
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400371Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400372
373Fixed various Debian packaging issues --- see debian/changelog for
374details. (Addresses Debian Bug: #506279)
375
376Programmer's Notes
377------------------
378
379Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
380Bug: #521602)
381
382Fix various gcc compilation warnings and other programming cleanups.
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400383(Addresses Red Hat Bugzilla: #486997)
Theodore Ts'odaf3c822009-04-19 23:06:45 -0400384
385Add support for building the blkid command statically.
386
Theodore Ts'oe60c25b2009-04-23 01:57:51 -0400387Add support for disabling the built-in blkid library in favor of a
388system-installed blkid implementation via the configure option
389--disable-libblkid.

Theodore Ts'ob2ca48f2009-01-27 19:51:00 -0500392E2fsprogs 1.41.4 (January 27, 2009)
393===================================
394
395Fixed a bug which could sometimes cause blkid to return an exit value
396of zero for a non-existent device (Addresses Debian Bug: #502541)
397
398Blkid will now recognize ext3 filesystems that have the test_fs flag
399set as ext3 filesystems.
400
401The blkid library will now recognize btrfs filesystems and swap
402devices currently used by user-level software suspend.
403
404Tune2fs now updates the block group checksums when changing the UUID
405to avoid causing e2fsck to complain vociferously at the next reboot.
406
407Tune2fs's inode size resizing algorithms have been fixed so it is not
408vastly inefficient for moderate-to-large filesystems, due to some
409O(n**2) and O(n*m) algorithms that didn't scale well at all.
410
411Fix tune2fs's inode resizing algorithm so it will not corrupt
412filesystems laid out for RAID filesystems; in addition, tune2fs will
413refuse to change the inode size for filesystems that have the flex_bg
414feature enabled. (This is a limitation in the current implementation
415of tune2fs -I.)
416
417E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
418filesystems with 32-bit block numbers, when the headers for 64-bit
419block numbers was added. This regression has been fixed.
420
421Debugfs's ncheck command has been fixed to avoid printing garbage
422characters at the end of file names.
423
424Fix resize2fs for ext4 filesystems. Some blocks that that need moving
425when shrinking filesystems with uninit_bg feature would not be moved.
426In addition, blocks and inode table blocks were not being correctly
427freed when shrinking filesystems with the flex_bg feable, which caused
428resize2fs -M to fail. Finally, when blocks are moved, make sure the
429uninitialized flag in extents is preserved.
430
431Fix bug which caused dumpe2fs to abort with an error if run on a
432filesystem that contained an external journal.
433
434Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
435for this in argv[0] to provide better legacy support for these
436distributions. This is a practice that should NOT be continued,
437however.
438
439Mke2fs now has a new option -U, which allows the user to specify the
440UUID that should be used for the new filesystem.
441
442Mke2fs will treat devices that are exactly 16TB as if they were 16TB
443minus one block. This allows users who have read that ext3 supports
444up to 16TB filesystems and who create a 16TB LVM to not get confused,
445since the true limit is really 16TB minus one block.
446
447E2fsck will no longer abort an fsck run if block group has an errant
448INODE_UNINIT flag.
449
450E2fsck now distinguishes between fragmented directories and fragmented
451files in verbose mode statistics and in the fragcheck report.
452
453Fix a bug in e2fsck which casued it double count non-contiguous
454extent-based inodes.
455
456E2fsck will leave some slack space when repacking directories to allow
457room for a few directory entries to be added without causing leaf
458nodes to be split right away.
459
460Fix a bug which caused e2fsck to crash when it comes across a
461corrupted interior node in an extent tree with the error message:
462"Error1: Corrupt extent header on inode XXXXXX"
463
464E2fsck problem descriptions involving the journal are no longer
465referred to as "ext3" problems, since ext4 filesystems also have
466journals.
467
468Fix a long-standing bug in e2fsck which would cause it to crash when
469replying journals for filesystems with block sizes greater than 8k.
470
471Update Catalan translation from the Translation Project.
472
473Fixed various Debian packaging issues --- see debian/changelog for
474details. (Addresses Debian Bugs: #503057, #502323, #511207)
475
476Programmer's Notes
477------------------
478
479Fix build of e2fsck.profiled, and add support for building profiled
480binaries in the misc directory if configured with --enable-profile.
481
482The ext2fs_open() function now performs more sanity checks on the
483superblock to avoid potential divide by zero errors by other parts of
484library.
485
486The ext2fs_read_inode_full() function now has a safety check to avoid
487a segmentation fault on corrupted filesystems.
488
489The ext2fs_new_inode() function now has a sanity check so that if the
490s_first_inode field in the superblock is insane, it will return
491EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
492
493To avoid segmentation faults, ext2fs_block_alloc_stats() and
494ext2fs_inode_alloc_stats() now validates the passed inode or block
495number to avoid overrunning an array boundary.
496
497Various signed/unsigned errors for variables containing block numbers
498have been fixed.
499
500Accomodations for gcc's stupidity in not realizing that constant
501strings that do not contain a '%' character are safe to use in format
502strings have been made so that distributions that want to compile
503e2fsprogs with -Werror=format-security have an easier time doing so.
504
505Added a new 64-bit getsize interface, ext2fs_get_device_size2().
506
507Added the utility make-sparse.c to the contrib directory.
508
509The ext2fs_block_iterate2() function now reflects errors from
510ext2fs_extent_set_bmap() to the caller, if the callback tries to
511change a block on an extent-based file, and ext2fs_extent_set_bmap()
512fails for some reason (for example, there isn't enough disk space to
513split a node and expand the extent tree.
514
515The ext2fs_block_iterate2() function will preserve the uninit flag in
516extents when the callback function modifies a block in an extent-based
517file.
518
519E2fsck will now flag filesystems that have an insane s_first_ino field
520in their superblock, and attempt to use a backup superblock to repair
521the filesystem.
522
523
Theodore Ts'odf547ae2008-10-11 18:40:13 -0400524E2fsprogs 1.41.3 (October 12, 2008)
525===================================
526
527E2fsck has been fixed so it prints the correct inode number for
528uinit_bg related problems.
529
530E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
531is available on linux. This can be disabled via a configuration
532option in /etc/e2fsck.conf.
533
534Fix a file descriptor leak in libblkid when checking to see if an ext4
535or ext4dev module exists.
536
537Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
538while trying to close a filesystem can lead to infinite loops.
539(Addresses Red Hat Bugzilla #465679)
540
541Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
542will cause resize2fs to drop into an infinite loop. (Addresses Red
543Hat Bugzilla: #465984)
544
545Add a check in the Unix I/O functions in libext2fs so that when a
546device is opened read/write, return an error if the device is
547read-only using the BLKROGET ioctl.
548
549Fix debugfs's ncheck command so that it prints all of the names of
550hardlinks in the same directory.
551
552Fix a bug in libblkid so it correctly detects whether the ext4 and
553ext4dev filesystems are available, so that the ext4dev->ext4
554fallback code works correctly.
555
556Programmer's Notes
557------------------
558
559Fix a parallel build problem by making sure util/subst is built before
560trying to build the lib/et directory. (Addresses Sourceforge Bug:
561#2143281)
562
563Updated "make depend" information for crc16.o

Theodore Ts'oc12125f2008-10-01 23:16:06 -0400566E2fsprogs 1.41.2 (October 2, 2008)
567==================================
568
569Fix e2fsck's automatic blocksize detection. This fixes a regression
570from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
571specifies a block number using the -b option if the blocksize option
572isn't also specified using -B. Unfortunately, users very commonly
573invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
574superblock; in fack e2fsck will often suggest this kind of command
575line. Oops.
576
577Enhance the debugfs's "ncheck" command so it will print all of the
578pathnames for the specified inodes. (Previously, in some cases ncheck
579might not print a pathname for an inode at all if some of the other
580inodes had multiple hard links.)
581
582Enhance debugfs's "hash" command so the hash seed can be specified via
583a command-line option. In addition, allow the hash algorithm to be
584specified by name instead of just by number.
585
586Fix e2fsck so that we don't accidentally print the translation file's
587header when asking the user a custom question so there is no prompt
588defined for a particular problem record. For example, the question
589"Run journal anyway" will get the PO header tacked on because e2fsck
590erroneously passed the null string to _(). (Addresses Launchpad Bug:
591#246892)
592
593Enhance badblocks so that it can test a normal file which is greater
594than 2GB.
595
596Enhance the badblocks command so that it displays the time and
597percentage complete when in verbose mode. (Addresses Debian Bug:
598#429739)
599
600Fix a potential memory leak in a error handling path in debugfs's
601ncheck function.
602
603Fix a potential memory corruption problem if a memory allocation fails
604in resize2fs.
605
606Fix the usage message for debugfs's logdump command to be consistent
607with its man manpage.
608
609Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
610and Sweedish translation from the Translation Project.
611
612Add documentation for the file I/O functions to the libext2fs.texinfo
613file. (Addresses Debian Bug: #484877)
614
615Update and clarified various man pages. (Addresses Launchpad Bug
616#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
617
618Fixed various Debian packaging issues --- see debian/changelog for
619details. (Addresses Debian Bug: #497619)
620
621Programmer's Notes
622------------------
623
624Fix a potential file descriptor leack in libcom_err by setting the
625close-on-exec flag for a fd used for debugging. (Addresses Red Hat
626Bugzilla #464689)
627
628Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
629has been carrying a patch for a long time to prevent a largely
630theoretical race condition if a multi-threaded application adds and
631removes error tables in multiple threads. Unfortunately SuSE's
632approach breaks compatibility by forcing applications to link and
633compile with the -pthread option; using pthread mutexes has
634historically been problematic. We fix this by using sem_post/sem_init
635instead.
636
637Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
638Sourceforge Bug: #2087502)
639
640Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
641libraries when using ELF shared libraries.
642
643Fix ELF shared library when building on systems that don't already
644have the e2fsprogs shared libraries already installed. (Addresses
645Sourceforge Bug: #2088537)
646
647Fix the pkg-config files so they work correctly when linking with
648static libraries and fix the include directory so programs don't have
649to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
650instead. (Addresses Sourceforge Bug: #2089537)
651
652Make sure ext2fs_swab64() is compiled for all platforms, and not just
653for x86. (Addresses Debian Bug: #497515)
654
655Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
656non-x86 platforms. (They had been removed for x86 earlier.)
657
658Fix diet libc compilation support, which had bitrotted due to lack of
659TLC. Fixing this improves general portability.
660
661When installing the link library when using ELF shared libraries,
662avoid using absolute pathnames if the link library and the shared
663library are installed in the same directory. (Addresses Sourceforge
664Bug: #1782913)
665
666Fix gen-tarball so it will work even if the top-level directory has
667been renamed to something other than "e2fsprogs". Also make
668gen-tarball print the size of the resulting tar.gz file.
669

Theodore Ts'o31d64872008-09-01 10:39:35 -0400671E2fsprogs 1.41.1 (September 1, 2008)
672====================================
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400673
674Many people are forgetting to update their mke2fs.conf file, and this
675causes ext3, ext4, and ext4dev filesystems won't get created with the
676proper features enabled. We address this in two ways. First, mke2fs
677will issue a warning if there is not definition for an ext3, ext4, or
678ext4dev filesystem and the user is trying to create such a filesystem
679type. Secondly, when installing from a source build, "make install"
680will provide basic configuration file handling for /etc/mke2fs.conf.
681If it exists, and does not mention ext4dev, it will be moved aside to
682/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
683be installed. If the existing /etc/mke2fs.conf file does mention
684ext4dev, then "make install" will install official mke2fs.conf file as
685/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
686they should look to see if any changes need to be merged.
687
Theodore Ts'o31d64872008-09-01 10:39:35 -0400688The mke2fs program will now create the journal in the middle of the
689filesystem, since this minimizes seek times on average for fsync-heavy
690workloads. In addition, mke2fs will now create journals using extents
691for filesystems that support them. This results in a more efficient
692encoding for the journal since it eliminates the need for using
693indirect blocks.
694
695The mke2fs program will avoid allocating an extra block to the
696journal. (Addresses Sourceforge Bug: #1483791)
697
698Mke2fs will correctly enforce the prohibition against features
699(specifically read-only features) in revision 0 filesystems. (Thanks
700to Benno Schulenberg for noticing this problem.)
701
702Mke2fs previously would occasionaly create some slightly non-optimally
703placed inode tables; this bug has been fixed.
704
705The mke2fs and tune2fs programs now print the correct usage message
706describing the maximum journal size. (Addresses Debian Bug: #491620)
707
708Add support for setting the default hash algorithm used in b-tree
709directories in tune2fs (from a command-line option) or mke2fs (via
710mke2fs.conf). In addition, change the default hash algorithm to
711half_md4, since it is faster and better.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400712
713The blkid library will now recognize MacOS hfsx filesystems, and
714correctly extract the label and uuid for hfs, hfsx, and hfsplus
715filesystems. (Addresses Sourceforge Feature Requests: #2060292)
716
Theodore Ts'o31d64872008-09-01 10:39:35 -0400717The blkid library has improved detection of JFS and HPFS filesystems.
718(Addresses Launchpad Bug: #255255)
719
720The blkid library is now much more efficiently handling devicemapper
721devices, mainly by no longer using the devicemapper library. This can
722speed up access for systems with a large number of device mapper
723devices.
724
725Blkid had a number of cache validation bugs in libblkid that have been
726fixed. (Addresses Debian Bug: #493216)
727
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400728Resize2fs will now properly close out the "updating inode references"
729progress bar so there is a newline printed before printing the final
730"resize is successful" message.
731
732Resize2fs will now correctly handle filesystems with extents and/o
733uninitialized block groups correctly when file/directory blocks need
734to relocated (i.e., when shrinking a filesystem or if the resize_inode
735is not present). To support this, the ext2fs library now supports
736initializing inode and block bitmaps that are not yet initialized when
737allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
738addition, e2fs_block_iterate2() can now support changing the location
739of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
740been optimized to avoid creating unnecessary new extents when updating
741the location of blocks in the extent tree. This will also help out
742e2fsck's recovery of obscurely corrupted filesystems with extents,
743when blocks are claimed by multiple inodes.
744
Theodore Ts'o31d64872008-09-01 10:39:35 -0400745Add support for on-line resizing ext4 filesystem with the flex_bg
746filesystem feature. The method for doing so is not optimal, but to do
747a better job will require kernel support.
748
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400749E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
750debugfs programs to not be able to read e2image files; the signed
751vs. unsigned bug in the code which read bitmaps from the e2image has
752been fixed. (Addresses Debian Bug: #495830)
753
754Resize2fs is now correctly managing the directory in-use counts when
755shrinking filesystems and directory inodes needed to be moved from one
756block group to another. This bug has been around since e2fsprogs
7571.26, and is largely harmless, but does cause a filesystem corruption
758which will be flagged by e2fsck after the filesystem has been shrunk.
759
760E2fsck will no longer issue spurious complaints about the inode size
761caused by very large extent-based files, and by blocks reallocated
762using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
763Kernel Bugzilla: #11341)
764
765Mke2fs will now set the creation timestamp on the lost+found directory
766and the root directory. (More generally, all new inodes created using
767the ext2fs library will correctly set the creation timestamp.)
768
769E2fsck now correctly calculates ind/dind/tind statistics in the
770presence of extent-based files. In addition, "e2fsck -v" will report
771statistics of the depth of extent trees in the filesystem. E2fsck can
772also give an inode fragmentation report using "e2fsck -E fragcheck"
773which can be useful when debugging the kernel block allocation
774routines.
775
Theodore Ts'o31d64872008-09-01 10:39:35 -0400776Fix support for empty directory blocks in ext4 filesystems with 64k
777blocksize filesystems.
778
779E2fsck will now print the depth of corrupt htree directories.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400780
781Debugfs's htree command now correctly understands extent-based
782directories. It will also print out the minor hash as well as the
783major hash.
784
Theodore Ts'o31d64872008-09-01 10:39:35 -0400785Debugfs has a new command which will print the supported features of
786e2fsprogs, to enable scripts to know whether the installed version of
787e2fsprogs can support a specific feature.
788
789Debugfs will now write files using extents for filesystems that
790support them.
791
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400792The error message printed by "tune2fs -I" if the inode size was too
793small was rather confusing, so it has been improved. Also, we won't
794try to create an undo log until we know that command-line-specified
795parameters such as "tune2fs -I <inode size>" are valid.
796
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400797Given some filesystems found "in the wild" that had non-zero block
798group checksums even though the uninit_bg/gdt_sum feature was not
799enabled, e2fsck would issue spurious error messages. Teach
800ext2fs_group_desc_csum_verify() to ignore the block group checksum
801entirely if the feature flag is not set. (Addresses Debian Bug:
802#490637)
803
804The blkid program will now print out a user-friendly listing of all of
805the block devices in the system and what they contain when given the
806-L option. (Addresses Debian Bug: #490527)
807
Theodore Ts'o31d64872008-09-01 10:39:35 -0400808The filefrag program now has a more accurate calculation for the
809number of ideal extents. (Addresses Debian Bug: #458306)
810
811The test I/O manager is now enabled by default, but its overhead is
812only incurred when it would be enabled via the TEST_IO_FLAGS or
813TEST_IO_BLOCK environment variables.
814
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400815Typographical errors in various program strings and usage messages
816have been fixed; most of these were pointed out by the e2fsprogs
817message catalog translators. (Thanks, translators!)
818
819Update and clarified various man pages, as well as some typographical
820errors in the libext2fs texinfo file.
821
822Fixed various Debian packaging issues --- see debian/changelog for
823details.
824
825Add Indonesian and update French, Polish, Dutch, German, Sweedish,
826Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
827#401092)
828
829Programmer's Notes
830------------------
831
832Fix portability problem with the badblocks group; for systems that
833don't have nanosleep(), try using usleep() instead.
834
835The "make check" target in the e2fsck directory now sets
836LD_LIBRARY_PATH before running the various e2fsck internal library
837regression tests.
838
839The crc32 regression test in the e2fsck library is now portable to
840greater varienty of environments, including big-endian systems and
841when cross-building e2fsprogs for embedded systems. (Addresses
842Sourceforge Bug: #2019287)
843
844The ext2fs_extent_set_bmap() had some bugs when setting the first
845block in a file, or when replacing a single block extent. Those cases
846fortunately were came up relatively rarely when e2fsck was checking
847files, but caused some problems when resize2fs was shrinking
848extent-based files.
849
Theodore Ts'o31d64872008-09-01 10:39:35 -0400850Fix a potential core-dumping bug in libe2p's iterate_on_dir()
851function.
852
853Various ext2fs library functions --- ext2fs_block_iterate2(),
854ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
855allocated memory to avoid memory leaks in all of their error return
856paths.
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400857
858Ext2ed was failing to build because masix support had been removed in
859the rest of e2fsprogs, so ext2ed no longer has masix support, either.
860
861The configure script now respects the LDFLAGS environment variable if
862it is set when configure is called. (Addresses Sourceforge Feature
863Request: #1937287)
864
865Libuuid is now more portable to the Windows platform. (Addresses
866Sourceforge Feature Request: #1937287)
867
868The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
869bare echo commands so that configure flags such as --quiet work
870correctly. (Addresses Sourceforge Patches: #2058794)
871
872A few uses of sprintf have been removed from the ext2fs library to
873make life easier for bootloaders with a limited libc environment.
874(Addresses Sourceforge Bug: #2049120)
875
876The ext2fs_read_inode() checks the validity of the inode number passed
877to it earlier, to avoid doing some needless work when it would fail
878anyway.
879
880The ext2fs_open() checks the validity of the blocksize parameter
881passed to it earlier, to avoid doing some needless work when it would
882fail anyway.
883
884Disable a very annoying automatic "%.sh -> %" GNU make rule in the
885top-level Makefile. That automatic rule is used to better support
886SCCS, but it caused problems for a particular niche distribution which
887likes to use configure.sh files to store the configure options used to
888build a package. Unfortuntaely GNU make will use the configure.sh to
889replace the configure script, resulting in a self-inflicted fork bomb
890leading to an out-of-memory crash.
891
Theodore Ts'o31d64872008-09-01 10:39:35 -0400892To support old GNU C compilers don't use C99/C++ comments, but only
893K&R style comments, and don't try to use __builtin_expect if __GNUC__
894is less than 3. (__builtin_expect is only supported for gcc versions
8952.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
896this is an optimization, we only try to use __builtin_expect for gcc 3
897and up.)

899In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
900__LITTLE_ENDIAN, which are only defined by glibc's header files and
901hence isn't portable.
902
903For the convenience for some distributions that need a static tune2fs,
904the Makefile for misc/ now has a tune2fs.static target.
905
906The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
907for extent-based files
908
909The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
910files.
911
912All source files no longer have any trailing white space.
913
914The io_channel_read_blk64() and io_channel_write_blk64() functions are
915now functions instead of C preprocessor macros to provide better
916forward compatibility.
917
918The e2fpsrogs translation template now expands the @x abbrevation.
919
920Various namespace leackages in libblkid, libe2p, and libext2fs have
921been fixed.
922
923Fix a parallel build problem in e2fsprogs.
924
Theodore Ts'o30ab7f42008-08-23 11:43:08 -0400925E2fsprogs is now more portable to Solaris.
926 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
927 are always present.
928 * Scripts do not assume that /bin/true is always in /bin
929 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
930 * Flush stdio handles before calling setbuf(), since Solaris will
931 discard any pending output to the stream.
932 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
933 picky about which C compiler can beused for SUSv3 conformance.
934 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
935 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
936 Since we need some SUSv3 functions, consistently use SUSv3 so
937 that e2fsprogs will build on Solaris using c99.
938 * Solaris C99 does not support varargs C preprocessor macros
939 * Solaris header files pollute the C namespace if in/netinet.h
940 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
941 typedef.
942 * Solaris ships with a pathetically ancient shell in /bin/sh so we
943 avoid the use of various more avanced shell constructs such as $().

Theodore Ts'o31d64872008-09-01 10:39:35 -0400945The "make rpm" command will now take some extra configure optiosn from

Theodore Ts'o92e49d82008-07-10 17:24:22 -0400955E2fsprogs 1.41 (July 10, 2008)
956==============================
Theodore Ts'o795de672008-06-18 00:50:05 -0400957
958Add support for ext4 filesystem features, in particular extents,
959uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
960support for checking journal checksums. Debugfs will print new
961superblock and inode fields that were defined for ext4. For example,
962the nanosecond and i_version fields of an inode, and the
963s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
964Note: Resize2fs doesn't currently support the combination of flex_bg
965and !resize_inode. (Addresses Debian Bug: #388452, #425477)
966
967Tune2fs can support migrating a filesystem from using 128 byte inodes
968to 256 byte inodes, so it can take advantage of the full features of
969ext4.
970
971Add support for "undo" support. E2fsck and mke2fs can optionally
972record an undo log which can replayed by the program e2undo.
973
Theodore Ts'o92e49d82008-07-10 17:24:22 -0400974E2fsck could damage a filesystem by trying to relocate inode tables
975due to corrupted block group descriptors, where the attempted inode
976table relocation would do far more harm than good. E2fsck has been
977fixed to detect this these sorts of corrupted block group descriptors
978much earlier in e2fsck processing, so it can try to use the backup
979superblock and block group descriptors first. This should be a much
980better strategy for recovering these types of corrupted filesystems.
981(Addresses Sourceforge Bug: #1840291)
982
Theodore Ts'o795de672008-06-18 00:50:05 -0400983E2fsck will display a more understandable message when the last check
984field in the superblock is in the future. (Addresses Debian Bug:
985#446005).
986
Theodore Ts'o92e49d82008-07-10 17:24:22 -0400987E2fsck now performs more extensive and careful checks of extended
988attributes stored in the inode.
989
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -0400990Enhance mke2fs to print a more explanatory error message when
991ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
992#488663)
993
994Fix mke2fs to use a default block size of 4k when formatting an
995external journal device. This is done by using a fixed filesystem
996type list that consists only of the single filesystem type "journal"
997when looking up configuration keys in /etc/mke2fs.conf. (Addresses
998Debian Bug: #488663)
999
Theodore Ts'o795de672008-06-18 00:50:05 -04001000Speed up how mke2fs writes the journal data blocks by writing the disk
1001blocks in larger chunks.
1002
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -04001003Fix blkid handling of stale devices. Fix a bug which could cause a
1004core dump while garbage collecting the blkid cache, and assure that
1005blkid_find_dev_with_tag() never returns a non-existent device. Also,
1006if a filesystem is found at a new /dev location, eliminate any
1007duplicate stale entries which can not be verified.
Theodore Ts'odaf3c822009-04-19 23:06:45 -04001008(Addresses Debian Bugs: #487758, #487783)
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -04001009
Theodore Ts'o795de672008-06-18 00:50:05 -04001010Add more paranoid checks for LVM volumes and swap partitions in
1011blkid's probe function, to reduce the chances of false positives.
1012
1013The mke2fs program now has a much more sophisticated system for
1014controlling configuration parameters of a newly created filesystem
1015based on a split filesystem and usage type system. The -t option to
1016mke2fs was a deprecated alias to -c; it now specifies a filesystem
1017type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1018separated usage list. The filesystem type information and type
1019information is used to extract configuration parameters from the
1020/etc/mke2fs.conf file.
1021
Theodore Ts'o795de672008-06-18 00:50:05 -04001022The mke2fs program will no longer complain and request the -f option
1023when the user tries to create a filesystem with greater than 2**31
1024blocks.
1025
Theodore Ts'o92e49d82008-07-10 17:24:22 -04001026When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1027adjust the mke2fs.conf file so filesystems for the Hurd are created
1028with a blocksize of 4096 and inode size of 128, which is all it knows
1029how to handle. (Addresses Debian Bug: #471977)
1030
Theodore Ts'o795de672008-06-18 00:50:05 -04001031Mke2fs will always make sure that lost+found always has at least 2
1032blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1033
Theodore Ts'o92e49d82008-07-10 17:24:22 -04001034Resize2fs will now print the minimum needed filesystem size if given
1035the -P option, and will resize the filesystem to the smallest possible
1036size if given the -M option.
1037
1038Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1039blocks are consumed during an off-line resize.
1040
Theodore Ts'o795de672008-06-18 00:50:05 -04001041The "ls" command in debugfs now supports the -p option, which causes
1042it to quote the filenames so that spaces or tabs in directory entries
1043are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
1044Sourceforge Feature Request: #1201667)
1045
1046Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1047e2image file.
1048
1049The chattr program will return a non-zero exit code in case of
1050failures, and error messages can be suppressed with the -f option.
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -04001051(Addresses Red Hat Bugzilla: #180596)
1052
1053Fix a bug in badblocks which caused it to overrun an array and likely
1054crash if more than 8 test patterns are specified using the -t option.
1055(Addresses Debian Bug: #487298)
Theodore Ts'o795de672008-06-18 00:50:05 -04001056
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -04001057Add support to badblocks to limit how quickly it reads from the disk
1058drive (so it can be used for background scrubbing), and so it will
1059abort after finding a given number of errors.
1060
Theodore Ts'o795de672008-06-18 00:50:05 -04001061Remove support for the legacy big-endian filesystem format which only
1062existed on extremely long-dead PowerPC kernels almost a decade ago.
1063
1064Remove MASIX support from e2fsprogs.
1065
1066Add I/O statistics reporting to e2fsck.
1067
Theodore Ts'oa41d5ac2008-07-07 15:10:16 -04001068Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
1069Czech translations.

1101
1102Fix the blkid regression test suite to tolerate older versions of
1103mkswap that don't support the -U option.
1104
Theodore Ts'o795de672008-06-18 00:50:05 -04001105A few library routines have been converted to support 64-bit block
1106numbers; in particular, the I/O manager functions, the test_io,
1107inode_io, and unix_io managers have all be converted to support 64-bit
1108operation.
1109
1110Debugfs can now be extended for use by test programs. See
1111lib/ext2fs/extents.c for an example for how it can be used. The test

1113additional commands by defining an auxiliary libss command table.
1114
1115The lazy_bg filesystem feature, which was only used by developer's
1116testing, has been removed since it has been largely supplanted by
1117uninit_bg. This also simplifies the code.

1151When deciding whether or not to revalidate a blkid cache entry, if the
1152device's mtime is newer than the last time the cached entry was
1153validated, force a revalidation.
1154
1155Fix a potential data corruption bug in e2fsck in the journal replay.
1156The chances of this is happening is extremely remote, especially the
1157default data=ordered or data=writeback modes. However, if a block
1158which has been journalled starts with the first four bytes 0xc03b3998,
1159when e2fsck replays the journal, those four bytes will be replaced
1160with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1161metadata to begin with those fatal 4 byte sequence, and unless
1162data=ordered mode is in use, data blocks are never journaled.

1248
1249Fixed e2image -I so it works on image files which are larger than 2GB.
1250
1251Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1252the size is larger than the number of blocks found in the inode, don't
1253try to allocate extra empty blocks at the end of the directory to make
1254up the difference; there's no point to doing that. In addition, if
1255the size is not a multiple of a blocksize, always fix it.
1256
1257E2fsck handled a pass 2 "should never happen error" by not giving
1258enough information and then core dumping. Unfortunately, it was all
1259too easy to trigger the "should never happen" situation if a
1260directory's inode size was not correct. This has been fixed, but
1261e2fsck has also been taught how to handle this situation more
1262gracefully, by simply removing the inode hash tree information, so
1263that it can be rebuilt again after e2fsck's pass 3. (Addresses
1264Launchpad Bug: #129395)
1265
1266Resize2fs had a bug resizing large inodes with extended attributes
1267that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1268completely on big-endian systems such as PowerPC. The bug should be
1269completely fixed now. Yay for regression test suites. (Addresses Red

1303depreciate the -s option, since it can result in filesystems which
1304e2fsck can't fix easily. There are very good reasons for wanting to
1305disable sparse_super; users who wants to turn off sparse_super can use
1306debugfs. (Addresses Sourceforge Bug: #1840286)
1307
1308Add missing options to mke2fs's usage message. (Addresses Sourceforge
1309Bug: #1751393)
1310
1311Fix bug in resize2fs when large (greater than 128 byte) inodes are
1312moved when a filesystem is shrunk; it was only moving the first 128
1313bytes, so extended attributes were not getting moved. (Addresses Red
1314Hat Bugzilla: #434893)
1315
1316E2fsck now prints an explicit message when the bad block inode is
1317updated, to avoid confusion about why the filesystem was modified.
1318(Addresses Sourceforge Bug: #756460)
1319
1320Allow mke2fs and tune2fs manipulate the large_file feature.
1321Previously we just let the kernel and e2fsck do this automatically,
1322but e2fsck will no longer automatically clear the large_file feature.
1323It still isn't really necessary to worry about this feature flag
1324explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
1325#258381)

1327Suppress message about an old-style fstab if the fstab file is empty.
1328(Addresses Debian Bug: #468176)
1329
1330Fix (really minor) bug in debugfs's find_free_block so it avoids
1331reporting a free block more than once if there are too few free blocks
1332in the filesystem. (Addresses Sourceforge Bug: #1096315)
1333
1334Change e2fsck to no longer clear the LARGE_FILES feature flag
1335automatically, when there are no more > 2GB files in the filesystem.
1336It's been almost a decade since there have been kernels that don't
1337support this flag, and e2fsck clears it quietly without telling the
1338user why the filesystem has been changed.
1339
1340Fix bug which could cause libblkid to seg fault if a device mapper
1341volume disappears while it is being probed. (Addresses RedHat

1346
1347Fix option syntax in dumpe2fs for explicit superblock and blocksize
1348parameters. What was currently documented in the man page has been
1349broken for some time, due to getopt() implementation changes. The
1350option sytax has been changed to one which is can be more portable
1351supported and which is consistent with the format for extended options
1352in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
1353
1354Add support to tune2fs to clear the resize_inode feature. This
1355requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)

1459===================================
1460
1461Fix a potential overflow big in e2image if the device name is too
1462long.
1463
1464Mke2fs will now create new filesystems with 256 byte inodes and the
1465ext_attr feature flag by default. This allows for much better future
1466compatibity with ext4 and speeds up extended attributes even on ext3
1467filesystems.
1468
1469Teach e2fsck to ignore certain "safe" filesystem features which are
1470set automatically by the kernel. Having the kernel set features
1471automagically behind the user's back is a bad idea, and we should try
1472to break the kernel of this habit, especially for the newer ext4
1473feature flags. But for now, we will try to avoid needless full checks
1474which can annoy users who are doing fresh installs.
1475
1476Add support in tune2fs and mke2fs for making a filesystem as being "ok
1477to be used with test kernel code". This will be needed for using test
1478filesystems with the latest ext4 kernel code.
1479
1480Change e2fsck -fD so that it sorts non-htree directories by inode
1481numbers instead of by name, since that optimizes performances much
1482more significantly. (Addresses-Sourceforge-Feature-Request: #532439)

1561
1562Fix fsck to only treat the '#' character as a comment at the beginning

1603===================================
1604
1605Fix a potential security vulnerability where an untrusted filesystem
1606can be corrupted in such a way that a program using libext2fs will
1607allocate a buffer which is far too small. This can lead to either a
1608crash or potentially a heap-based buffer overflow crash. No known
1609exploits exist, but main concern is where an untrusted user who
1610possesses privileged access in a guest Xen environment could corrupt a
1611filesystem which is then accessed by the pygrub program, running as
1612root in the dom0 host environment, thus allowing the untrusted user to
1613gain privileged access in the host OS. Thanks to the McAfee AVERT
1614Research group for reporting this issue. (Addresses CVE-2007-5497.)
1615
1616Fix hueristics in blkid which could cause a disk without partitions to
1617be incorrectly skipped when a loopback device is present. (Addresses

1619
1620Fix e2image so that in raw mode it does not create an image file which
1621is one byte too large.
1622
1623Change mke2fs's usage message so it recommends the preferred -E option
1624instead of the deprecated -R option.
1625
1626Enhance the blkid library so it will recognize squashfs filesystems.
1627(Addresses Red Hat Bugzilla #305151.)
1628
1629Enhance e2fsck so it will force the backup superblocks to be backed up
1630if the filesystem is consistent and key constants have been changed
1631(i.e., by an on-line resize) or by e2fsck in the course of its
1632operations.
1633
1634Enhance blkid's detection of FAT filesystems; so that USB disks with
1635only a single bootable partition will not get missed.
1636
1637E2fsck will no longer mark a filesystem as invalid if it has time
1638errors (i.e., if superblock mount time or last write time is in the
1639future) and the user refuses to fix the problem.
1640
1641The Ubuntu init scripts don't properly set the system time correctly
1642from hardware clock if the hardware clock is configured to tick local
1643time instead of GMT time. Work around this as best as we can by
1644providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
1645be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
1646Bug #131201.)
1647
1648Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
1649Hat Bugzilla #151533.)
1650
1651Fix e2fsck so that if the superblock is corrupt, but still looks
1652vaguely like an ext2/3/4 superblock, that it automatically tries to
1653fall back to the backup superblock, instead of failing with a hard
1654error.
1655
1656Make the e2fsprogs program more robust so that they will not crash
1657when opening a corrupt filesystem where s_inode_size is zero.
1658
1659Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
1660arguments are detected as such and the parse error is reported to the
1661user. (Addresses Debian Bug #435381.)
1662
1663Change e2fsck so it will not complain if a file has blocks reallocated
1664up to the next multiple of a system's page size.
1665
1666Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
1667about (valid) filesystems where the inode table extends to the last
1668block of the block group. (Addresses Red Hat Bugzilla #214765.)

1698
1699Fixed a corner case bug ext2fs_unlink() when trying to delete the
1700first directory entry in a directory block and the last directory
1701entry in the previous directory block is not in use. Fortunately
1702ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in

1719================================
1720
1721A recent change to e2fsck_add_dir_info() to use tdb files to check
1722filesystems with a very large number of filesystems had a typo which
1723caused us to resize the wrong data structure. This would cause a
1724array overrun leading to malloc pointer corruptions and segfaults.
1725Since we normally can very accurately predict how big the the dirinfo
1726array needs to be, this bug only got triggered on very badly corrupted
1727filesystems.
1728
1729Fix a bug in e2fsck which caused it to incorrectly salvange
1730directories when the last entry's rec_len is bogusly too big. This
1731resulted in a nonsense filesystem corruption to be reported, and

1749The Turkish translation has a bug in it where it has the translation
1750of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
1751@E, recursively, forever, until the stack fills up and e2fsck core
1752dumps. We fix this by making e2fsck stop @-expansions after a
1753recursive depth of 10, which is far more than we need.

1760which is used by mke2fs if the /etc/mke2fs.conf is not present.
1761(Addresses SourceforgeBug: #1745818)
1762
1763Improve the config/parse_types.sh helper script. Fix a potential
1764security problem if e2fsprogs is built as root (as Gentoo does!). In
1765addition fix the script and how it is called from the configure script
1766so that it does the right thing when cross-compiling. (Fixes Gentoo
1767bug: #146903)
1768
1769Update Vietnamese, French, and Dutch PO files from the Translation
1770Project. Also created a new e2fsprogs.pot file for translator.
1771
1772Fix bogus strip permission errors when building under Debian. When
1773building the e2fsprogs dpkg's, the dh_strip command emits a large
1774number of error messages caused by the permissions not being right.
1775So run dh_fixperms before running dh_strip.

1777Programmer's Notes:
1778-------------------
1779
1780Add new function: profile_set_default(). This function sets the value
1781of the pseudo file "<default>". If the file "<default>" had
1782previously been passed to profile_init(), then def_string parameter
1783will be parsed and used as the profile information for the "<default>"
1784file.
1785
1786Fix mk_cmds's error reporting so that it is unambiguous that it is the
1787mk_cmds script which is generating the error. (Obviates Gentoo patch:
1788e2fsprogs-1.32-mk_cmds-cosmetic.patch)
1789
1790Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
1791priority" environment variable that overrides all others, where as
1792LANG is the lowest priorty environment variable. If LC_ALL is set, it
1793doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
1794the all the rest are set. This will assure that the locale when
1795running the test suites is the "C" locale. (Obviates Gentoo patch:
1796e2fsprogs-1.38-tests-locale.patch)

1800==============================
1801
1802Fix divide by zero error in blkid's NTFS probing logic.
Theodore Ts'od7b64722007-06-24 17:32:47 -04001803
1804Add new blkid -g option which causes the blkid cache to be garbage
1805collected.
1806
1807Fix a bug in libblkid which could cause the internal field bid_type to
1808become corrupted. Fortunately bid_type isn't used much, and bid_label
1809and bid_uuid is only used by debugging code, so the impact of this bug
1810was very minor.
1811
1812Mke2fs will now store the RAID stride value when a filesystem is
1813created with a requested RAID stride, and then use it automatically in
1814resize2fs.
1815
1816Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
1817isn't too big. In some cases Lustre users have tried specifying an
1818inode size of 4096 bytes, while keeping an inode ratio of one inode
1819per 4096 bytes.
1820
1821Improve sanity check in e2fsck's algorithm for finding a backup
1822superblock, so that it won't accidentally find a superblock that was
1823located in the journal, and then later reject it as being not a valid
1824backup superblock.
1825
1826Fix e2fsck get_size logic so that it will work with the Linux floppy
1827driver. The Linux floppy driver is a bit different from the other
1828block device drivers, in that if the device has been opened with
1829O_EXCL, it disallows another open(), even if the second open() does
1830not have the O_EXCL flag. (Addresses Debian Bug: #410569)
1831
1832Fix error checking of badblock's last-block and start-block arguments.
1833(Addresses Debian Bug: #416477)
1834
1835Fix e2fsck so that it doesn't overwrite the backup superblocks when
1836recovering a journal until the master superblock has been confirmed as
1837being sane.
1838
1839Change the blkid library to be much more paranoid about concluding
1840that a partition contains an NTFS filesystem, and fetch the UUID and
1841LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
1842#110138)
1843
1844Factor out the code which sets the default journal size and move it
1845into libext2fs.
1846
1847Enhance e2fsck so it will recreate the ext3 journal if the original
1848journal inode was cleared to due it being corrupt after finishing the
1849filesystem check.
1850
1851Fix e2fsck so that it updates the journal inode if it is corrupted and
1852the backup journal information from the superblock was successfully
1853used to recover the filesystem.
1854
1855Fix e2fsck so that it checks all of the blocks in the journal inode
1856for validity. The original code only checked the direct blocks to
1857make sure the journal inode was sane. Unfortunately, if some or all
1858of the indirect or doubly indirect blocks were corrupted, this would
1859not be caught.
1860
1861Add support in blkid to detect LUKS encrypted partitions.
1862
1863Add extra sanity checks for extended attributes in the case where the
1864size is zero but the offset is very large.
1865
1866Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
1867and ext2fs_get_next_inode_full().
1868
1869Clarify the copyright licenses used by the various libraries in
1870the top-level COPYING file (Red Hat Bugzilla: 166058)
1871
1872Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
1873
1874Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
1875
1876Remove check in e2fsck which requires EA's in inodes to be sorted;
1877they don't need to be sorted, and e2fsck was previously wrongly
1878clearing unsorted EA's stored in the inode structure.
1879
1880Allow mke2fs or tune2fs to create a substantially larger journal (up
1881to 10,240,000 blocks).
1882
1883Fix MD superblock detection, and make sure the correct UUID is
1884reported from the MD superblock.
1885
1886Fix a signed vs. unsigned bug in debugfs.
1887
1888Enhance debugfs's date parser so that it accepts integer values.
1889
1890Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
1891file with multiply claimed blocks is hard linked. or not at all if the
1892root directory contains shared blocks
1893
1894Enhance debugfs so it can modify the block group descriptors using the
1895command set_block_group_descriptor.
1896
1897Improve e2fsck's reporting of I/O errors so it's clearer what it was
1898trying to do when an error happens
1899
1900Fix a bug in in how e2fsprogs byte swaps inodes containing fast
1901symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
1902#232663 and LTC Bugzilla: #27634)
1903
1904Fix potential file descriptor leak in ext2fs_get_device_size() in an
1905error case.
Theodore Ts'oa0d42542007-04-07 11:05:10 -04001906
1907Add libreadline.so.5 support to libss.
1908
1909Impove badblocks -n/-w exclusive usage message.
1910
1911Fix dump_unused segfault in debugfs when a filesystem is not open
1912
1913Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
1914
1915Allow the debugfs lcd command to work w/o a filesystem being open.
1916(Addresses LTC Bugzilla #27513)
1917
1918Fix e2fsck to clear i_size for special devices with a bogus i_blocks
1919field on the first pass.
1920
1921Fix e2fsck to set the file type of the '..' entry when connecting
1922a directory to lost+found. (Addresses Lustre Bug: #11645)
1923
1924Enhance e2fsck to recover directories whose modes field were corrupted
1925to look like special files. This is probably only useful in
1926artificial test cases, but it will be useful if we ever do the "inodes
1927in directory" idea for ext4.
1928
1929Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
1930#412614)
1931
1932Fix resize2fs parsing of size parameter (in sector units). This was
1933actually a bug in libe2p's parse_num_blocks() function. When handling
1934the 's' suffix, it was ignoring the blocksize information passed in
1935from the caller and always interpreting the number in terms of a 1k
1936blocksize. (Addresses Debian Bug: #408298)
1937
1938There was a floating point precision error which could cause e2fsck to
1939loop forever on really big filesystems with a large inode count.
1940(Addresses Debian Bug: #411838)
1941
1942Fix memory leak in ext2fs_write_new_inode()
1943
1944Add support for using a scratch files directory to reduce e2fsck's
1945emory utilization on really big filesystems. This uses the TDB
1946library. See the [scratch_files] section of the e2fsck.conf man page
1947for more details.
Theodore Ts'o7809bc52006-11-14 23:49:07 -05001948
1949Fixed type-punning bug which caused dumpe2fs to crash on the Arm
1950platform (Addresses Debian Bug: #397044)
1951
1952Add explanatory message to badblocks that -n and -w are mutually exclusive
1953(Addresses Debian Bug: #371869)
1954
1955Allow debugfs and dumpe2fs to support fs features under development.
1956
1957Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
1958ext2fs_open() , which allows application to open filesystes with features
1959which are currently only partially supported by e2fsprogs.
1960
1961Allow unix_io to support offsets greater than 2G (Addresses
1962SourceForge Bug: #1547922)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001963
1964Fixed overflow and signed/unsigned problems caused by the number of
Theodore Ts'o7809bc52006-11-14 23:49:07 -05001965blocks or inodes exceeding 2**31 or being close to 2**32-1.
1966
1967Add support for unsigned directory hash calculations with hints in the
1968superblock to fix cross-architectural portability for htree
1969directories with filenames where the high 8th bit is set. (Addresses
1970Debian: #389772)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04001971
1972Fix resize2fs so that it gives user-intelligible error messages if the
1973filesystem or the kernel does not support on-line resizing.
1974(Addresses Debian Bug: #380548)
1975
1976Require mke2fs -F -F for really dangerous operations, since -F is
1977needed for less dangerous operations such as creating filesystems
1978images in regular files, or creating filesystems on whole block
1979devices. These relatively innocuous usages should NOT be confused
1980with running mke2fs on an apparently-mounted or in-use filesystem.
1981
1982Allow the default inode size to be specified into the mke2fs.conf
1983file.
1984
1985Make the smallest default journal size is big enough so that on-line
1986resizing should always work.
1987
1988Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
1989#1531372)
1990
1991Fix debugfs coredump when lsdel is run without an open filesystem
1992(Addresses Debian Bug: #378335)
1993
1994Fix debugfs display bug us that bytes that have the high bit set are
1995displayed as "ec" instead of "ffffffec".
1996
1997Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
1998
1999Device mapper scanning wasn't working in the blkid library because the
2000pathnames had an extra "/dev" when they were being probed.
2001
2002Add GFS/GFS2 support to the blkid library.
2003
2004Fix blkid support of empty FAT filesystem labels.
2005
2006Avoid recursing forever (or for a long time) when the blkid library
2007searches for a device and there are symlinks to directories in /dev.
2008
2009Avoid unaligned halfword access in blkid when accessing FAT
2010superblocks, as this will cause Sparc/Solaris systems to throw a
2011SIGBUS error.
2012
2013The latest devmapper libraries requires pthreads, add -lpthreads to
2014the static link libraries for e2fsck.static if devmapper is enabled.
2015(Addresses Debian bug: #388718)
2016
2017Improve the (non-installed, for experts only) findsuper program by
2018printing the uuid and label from the superblocks, as well as the
2019starting and ending offsets of the filesystem given the information in
2020the superblock. Omit by default printing superblocks that are likely
2021found in located in an ext3 journal unless an explicit -j option is
2022given.
2023
Theodore Ts'o80dda9b2007-12-03 18:33:39 -05002024Updated Spanish, French and Dutch translations and added Catalan
2025translation. (Addresses Debian bug: #411562)
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002026
2027Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2028determining a partition's size, since binary searching to determine
2029the device doesn't work on FreeBSD.
2030
Theodore Ts'od7b64722007-06-24 17:32:47 -04002031Documentation about UUID's is available in enough places, and it's
2032awkward to deal with debian-legal's insanities. So I'm caving in the
2033"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2034don't have do the dfsg tarball. Also remove the rule that only tried
2035to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2036e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
2037
2038Fix the info-dir line so that the menu name does not contain a .info
2039prefix. First of all, it's ugly, secondly, it causes the install-info
2040command to fail to remove the com_err info file from the
2041/usr/share/info/dir file when the comerr-dev package is removed and
2042purged. (Addresses Debian Bug: #401711)
2043
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002044Fixed spelling mistakes, typos, and otherwise clarified man pages.

2052Programmer's notes:
2053-------------------
2054
Theodore Ts'oa0d42542007-04-07 11:05:10 -04002055E2fsck now supports the %It expansion when printing a problem report.
2056It will print the type of the inode in the problem context.
2057
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002058Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
2059(Addresses Sourceforge Bug: #1565561)
2060
2061Remove unused variables and other lint/gcc -Wall cleanups
2062
2063Add check to ext2fs_get_device_size() so it will return EFBIG for for
2064filesystems contained in regular files where the filesystem image size
2065is returned by stat64().
2066
Theodore Ts'o7809bc52006-11-14 23:49:07 -05002067Set local environment variables to C so mk_cmds and compile_et always
2068work. (Addresses SourceForge Bug: #1532177)
2069
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002070Added the 64-bit byte swapping function ext2fs_swab64().
2071
2072Added two new helper functions to prevent 2**31/2**32-1 overflow
2073problems: ext2fs_div_ceil() and e2p_percent().
2074
2075Create new ext2fs library inline functions ext2fs_group_first_block()
2076and ext2fs_group_last_block() in order to calculate the starting and
2077ending blocks in a block group.
2078
2079Create the generated files read-only to remind developers not to edit them.
2080
Theodore Ts'o7809bc52006-11-14 23:49:07 -05002081Add support for autoconf 2.60 (with backwards compatibility for older
2082versions of autoconf).
2083
Theodore Ts'o26bcc2c2006-10-02 13:34:48 -04002084Added an "make rpm" target to top-level Makefile
2085
2086Added various FreeBSD portability fixes.
2087
2088Exclude mercurial files from the RPM build tree to speed up copy/build.
2089
2090Use root_sysconfdir to define the locations of mke2fs.conf and
2091e2fsck.conf instead of using a hard-coded /etc pathname.
2092
2093Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2094
2095Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2096
2097If diff -u is supported, use it to report test failures.
2098
2099Updates/improvements to RPM spec file
2100
Theodore Ts'o7809bc52006-11-14 23:49:07 -05002101Add on-disk format definitions for the following new features:
2102EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2103EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2104EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2105
2106Add a new make target "checked-failed" in the tests directory which
2107reruns any failed tests
2108
2109Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2110
Theodore Ts'oa0d42542007-04-07 11:05:10 -04002111Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2112pointer dereferences, memory leaks, etc. None were security-criticial
2113problems.
2114
2115Fix up usage and decrement error messages in the test_icount program
2116
2117Add debugging code to the com_err library; if the environment variable
2118COMERR_DEBUG is set to 1, print out debugging messages as error tables
2119are added and removed from the com_err library. If the
2120COMERR_DEBUG_FILE environment variable is set (and the process is not
2121setuid) the debugging messages may be redirected to a file.
2122
2123Change all of the e2fsprogs programs to use the newer add_error_table()
2124and remove_error_table() interfaces instead of the much older
2125initialize_*_error_table() function.
2126
2127Add TDB support into the ext2fs library. This allows us to have a
2128guaranteed library we can count on always being present so we can
2129store data in an on-disk database.
2130
2131Add support for using TDB to store the icount data, so we don't run out
2132of memory when checking really large filesystems.
2133
Theodore Ts'od7b64722007-06-24 17:32:47 -04002134Change the regression test suite so that it skips empty test directories.
2135
2136Define the l_i_iversion field in ext2_inode. The l_i_version field is
2137now defined from the old l_i_reserved1 field in the ext2 inode. This
2138field will be used to store high 32 bits of the 64-bit inode version
2139number.
2140
2141Add Makefile production rule for e2fsprogs.spec in case it gets
2142deleted.
2143
2144Add new function profile_get_uint() to allow for a clean way to fetch
2145unsigned integers from the context.
2146
2147Add test to make sure the ext2 superblock structure is 1024 bytes.
2148
2149Fix typo in name of f_dup4 regression test
2150
2151Add new function blkid_gc_cache() which performs a garbage collection
2152pass on the /etc/blkid.tab file.
2153
2154The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2155general, only e2fsck (after the filesystem is clean), tune2fs, and
2156resize2fs should change the backup superblocks by default. Most
2157callers of ext2fs_open() should not be touching any superblock fields
2158which require the backups to be touched.
2159
2160Add new function to libext2fs, ext2fs_default_journal_size(), which
2161returns the default journal size.

2171configure the filesystem features, blocksize, and inode_ratio for
2172different filesystem types.
2173
Theodore Ts'o6c094752006-05-29 11:47:25 -04002174Mke2fs will now create filesystems hash trees and on-line resizing

Theodore Ts'o34a26112006-03-29 20:40:23 -05002177The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2178filesystem device node in exclusive mode to prevent accidents by
2179system administrators. In the case of resize2fs and mke2fs, it will
2180only use exclusive mode if the filesystem is not mounted.
2181
2182Fixed a bug in mke2fs which caused it to to fail when creating the
2183resize inode for large filesystems. (Addresses Debian Bug #346580)
2184
Theodore Ts'obae55642006-05-14 17:31:48 -04002185When allocating space for the RAID filesystems with the stride
2186parameter, mke2fs will now place each portion of the group's inode
2187table right up after the superblock (if present) in order to minimize
2188fragmentation of the freespace.
2189
2190Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2191efficiently by writing the inode and block bitmaps in one pass, thus
2192reducing the number of disk seeks required.
2193
Theodore Ts'o34a26112006-03-29 20:40:23 -05002194Add support for on-line resizing to resize2fs.
2195
2196Fix blkid library so that logic to determine whether or not a device's
2197cached information in /etc/blkid.tab needs to be verified or not
2198doesn't get confused by a system clock which is insane (for example,
2199if the battery is dead on a Macintosh running PPC Linux. (Addresses
2200Red Hat Bug: #182188)
2201
2202The blkid library will now store the UUID of the external journal used
2203by ext3 filesystems, so that in the future, the userspace mount binary
2204can use this to find the location of the external journal and pass
2205this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -05002206
2207E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -05002208control how various options should be handled. See the e2fsck.conf
2209man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -05002210
Theodore Ts'o34a26112006-03-29 20:40:23 -05002211E2fsck now prints an explanatory message when delaying a filesystem
2212check when the system is running on battery. (Addresses Debian Bug:
2213#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002214
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002215E2fsck will detect if the superblock's last mount field or last write
2216field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -05002217#327580) These problems will be fixed automatically in preen mode
2218since Debian's boot sequence bogusly doesn't set the time correctly
2219until potentially very late in the bootup process, and this can cause
2220false positives which will cause users' systems to fail to boot.
2221(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002222
Theodore Ts'o34a26112006-03-29 20:40:23 -05002223E2fsck now checks to see if the superblock hint for the location of
2224the external journal is incorrect, and if so, offer to update it.
2225(Addresses Debian Bug: #355644)
2226
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002227Fix e2fsck from segfaulting on disconnected inodes that contain one or
2228more extended attributes. (Addresses Debian Bug: #316736, #318463)
2229
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002230E2fsck will stop and print a warning if the user tries running a
2231read/write badblocks test on a read-only mounted root filesystem.
2232
Theodore Ts'obae55642006-05-14 17:31:48 -04002233Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2234C. Thompson for pointing these out; they were originally found using
2235Coverity.)
2236
Theodore Ts'of3227852005-12-31 16:45:29 -05002237When resizing a file containing a filesystem, resize2fs will expand or
2238truncate a file as necessary. (Addresses Debian Bug: #271607)
2239
Theodore Ts'obae55642006-05-14 17:31:48 -04002240Resize2fs will now automatically determine the RAID stride parameter that
2241had been used to create the filesystem, and use that for newly created
2242block groups. The RAID stride parameter may also be manually specified
2243on the command line using the new -S option to resize2fs.
2244
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002245Fix mke2fs so that it correctly creates external journals on
2246big-endian machines (such as a S/390).
2247
Theodore Ts'obae55642006-05-14 17:31:48 -04002248Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2249fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2250Chambraud for pointing this out.)
2251
2252Dumpe2fs will now print the size of the journal (if present).
2253
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002254Fix debugfs's set_inode_field command so it can properly set the frag,
2255fsize, uid_high, gid_high, and author fields in the inode instead of
2256silently failing, and so that setting the i_size actually sets i_size
2257correctly.
2258
2259Add a new debugfs command, set_current_time, which sets fs->now so
2260that regression test suites can repeatedly modify the filesystem's
2261last_write fields.
2262
Theodore Ts'o34a26112006-03-29 20:40:23 -05002263Fix a bug in debugfs's icheck which would incorrectly report the owner
2264of an extended attribute block.
2265
Theodore Ts'obae55642006-05-14 17:31:48 -04002266Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2267print a usage message when an illegal option character is given.
2268
Theodore Ts'o6c094752006-05-29 11:47:25 -04002269Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2270so it won't core dump. (Addresses SourceForge bug #1424311)
2271
Theodore Ts'obae55642006-05-14 17:31:48 -04002272Fix mklost+found so that it creates a full-sized directory on
2273filesystems with larger block sizes.
2274
2275Fix a file descriptor leak in blkid library.
2276
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002277Fix a display bug in "badblocks -sv" so that the done message properly
2278clears the block number at the end of the test. (Addresses Debian Bug
2279#322231)
2280
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002281Allow fractional percentages to the -m option in mke2fs and tune2fs
2282(Addresses Debian Bug: #80205)
2283
2284Use fstat/fstat64 in getsize.c if the the target is a regular file,
2285instead of attempting to do a binary search. Fix some fd leaks in
2286error cases.
2287
Theodore Ts'o34a26112006-03-29 20:40:23 -05002288Add support for device mapper library to the blkid library to ensure
2289that the "best" (i.e., leaf) device is probed by the blkid library.
2290
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002291Fix the blkid library so that it notices when an ext2 filesystem is
2292upgraded to ext3.
2293
2294Improve the blkid's library VFAT/FAT detection; it now understands
2295labels stored in the root directory, and is more paranoid about
2296checking the FAT superblock values.
2297
Theodore Ts'o34a26112006-03-29 20:40:23 -05002298Fixed a fd leak in the uuid library which was causing problems for the
2299LVM tools. (Addresses Debian Bug: #345832)
2300
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002301Add support for the reiser4 and software suspend partitions to the
2302blkid library. Also add support for extract the label from iso9660
2303filesystems.
2304
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002305Fix a compile_et bug which miscount the number of error messages if
2306continuations are used in the .et file.
2307
2308Add extra sanity checks to protect users from unusual cirucmstances
2309where /etc/mtab may not be sane, by checking to see if the device is
2310reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
2311#319002)
2312
Theodore Ts'o34a26112006-03-29 20:40:23 -05002313Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian

Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002316Fix use-after-free bug in e2fsck when finishing up the use of the
2317e2fsck context structure.
2318
Theodore Ts'o34a26112006-03-29 20:40:23 -05002319Fixed spelling mistakes, typos, and otherwise clarified man pages and
2320documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

2330Programmer's notes:
2331-------------------
2332
Theodore Ts'o7e2ec012006-04-22 04:29:16 -04002333Update config.guess and config.sub to latest version (2006-02-23) from
2334FSF.
2335
2336Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
2337Bugs: #360661, #360317)
2338
Theodore Ts'o34a26112006-03-29 20:40:23 -05002339Fixed the Makefile so that they work correctly on newer versions of
2340GNU make (i.e., 3.81).
2341
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002342Add valgrind support to the regression test suites, and eliminate
2343false positives from valgrind.
2344
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002345Add a regression test suite for the blkid library.
2346
Theodore Ts'of2b74cd2005-08-22 01:20:23 -04002347Fix a fencepost error in resize2fs caught by valgrind.
2348
Theodore Ts'o4c02c412005-12-09 19:20:01 -05002349Fix compiler warnings about missing memcpy prototypes.
2350
2351We no longer have the sparc assembly code in the header file any more,
2352so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2353break compiles on the sparc architectures when using gcc.
2354
2355In the libext2fs library, add the new field fs->now which if non-zero
2356is used instead of the system time when setting various filesystem
2357fields (last modified time, last write time, etc.)
2358
2359Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2360ext2fs.h which is needed since the inline functions use memcpy().
2361(Addresses Sourceforge Bug #1251062)
2362
2363Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2364the build system when building files in the util directory which are
2365needed during the build process. This avoids potential problems when
2366cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2367are not recognized as valid by the host compiler. (Addresses
2368Sourceforge Bug #1261547)
2369
2370Clean up the blkid library by making the superblock and generic i/o
2371functions to be more generic. Clean up interface to the probe
2372function, and fix memory leak. Finallly, remove an unneeded reference
2373to probe.h in the lib/blkid/resolve.c
2374
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05002375Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2376of invalid block #'s.
2377
Theodore Ts'o34a26112006-03-29 20:40:23 -05002378The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2379indicate that the the function read/writes the memory location.
2380
Theodore Ts'o3285a9c2005-12-10 23:05:30 -05002381Fix various gcc -Wall complaints.
2382
2383Add a dependency to make sure that the subdirectories are created
2384before creating all of the object files, in order to address parallel
2385build problem in the library Makefiles. (Addresses Sourceforge Bug:
2386#1261553)
2387
2388Add $(LDFLAGS) to the command line argument when generating an ELF or
2389Solaris shared library, to allow cross-compile and other builds that
2390might need to specify -L paths to needed libraries. (Addresses
2391Sourceforge Bug #1261549)
2392
Theodore Ts'obae55642006-05-14 17:31:48 -04002393Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2394intended for testing purposes. It allows an ext2/ext3 developer to
2395create very large filesystems using sparse files where most of the
2396block groups are not initialized and so do not require much disk
2397space. Eventually it could be used as a way of speeding up mke2fs and
2398e2fsck for large filesystem, but that would be best done by adding an
2399RO_COMPAT extension to the filesystem to allow the inode table to be
2400lazily initialized on a per-block basis, instead of being entirely
2401initialized or entirely unused on a per-blockgroup basis.
2402
Theodore Ts'o6c094752006-05-29 11:47:25 -04002403Fix backwards compatibility so e2fsprogs will better compile on Linux
24042.0.35 systems.
2405
2406Make test scripts more robust against locale-related environment variables
2407
2408Fix type warning problem with sizeof() in ext2fs_open2().
2409
2410Fix type warning problem with time_t in debugfs.

Theodore Ts'ofea95ff2005-07-01 17:31:55 -05002413E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -04002414==============================
2415
2416Fix blkid's test programs (built with "make check") compile correctly
2417even without "configure --enable-blkid-debug".
2418
2419Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2420type aliasing rules on newer gcc compilers. (Addresses Red Hat
2421Bugzilla ##161183.)
2422
2423Fix com_err library to make it more compatible with recent changes
2424made to the com_err library in MIT Kerberos V5 version 1.4.
2425(Addresses Sourcefroge Bug #1150146)
2426
2427General cleanup of messages printed by e2fsprogs programs for grammar,
2428consistency, and to make life easier for translators. Fixed a few
2429strings containing English that had not been marked as needing
2430translations. Removed strings that do not need to be translated, to
2431make life easier for translators.
2432
2433Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2434test to see if a device appears to be in use instead of just relying
2435on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
2436
2437Fix portability problem in the filefrag program affecting platforms
2438where the size of an integer is smaller than the size of a long.
2439(Addresses Debian Bug #309655)
2440
2441Mke2fs will now use a larger journal by default for filesystems
2442greater than 4GB. (128 MB instead of 32MB).
2443
2444Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2445unless forced. This is to avoid signed vs. unsigned kernel bugs in
2446block numbers that still need to be fixed.
2447
2448The blkid program has a new option which will more efficiently search
2449for device when it is known (or expected) that only one matching
2450device will be found in the system, such as when doing a lookup by
2451UUID.
2452
2453Debian's e2fsprogs-specific initrd fragment will avoid including
2454unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2455and LD_LIBRARY_PATH, and filtering out libraries found in
2456/etc/ld.so.preload. (Addresses Debian Bug: #304003)
2457
2458Fixed a potential portability issue in the blkid programs for
2459architectures where the char type is unsigned. (Addresses Sourceforge
2460Bug: #1180585)
2461
2462Fix a bug in filefrag so that it doesn't falsely count an extra
2463discontinuity when the first block found is an indirect block.
2464(Addresses Debian Bug #307607).
2465
2466Fix blkid's recognition of cramfs filesystems, and enhance it to be
2467able to handle cramfs labels.
2468
2469Fix debugfs's stat command to not core dump when a filesystem is not
2470open.
2471
2472Fix e2fsck's handling of error conditions caused by the resize inode
2473claiming blocks that are also used by other inodes, a filesystem
2474corruption which was commonly caused by a bug in Fedora Core 3's
2475resize2fs program.
2476
2477Fixed bug in filefrag which caused it to fail on non-ext2/3
2478filesystems. (Addresses Debian Bug: #303509)
2479
2480If the superblock last mount time indicates that the system clock may
2481not be accurate, then e2fsck will omit checking inodes' deletion time
2482field for indications of a potential corrupted orphaned inode list.
2483(Previously e2fsck only ommited these LOW_DTIME checks when the
2484superblock's last write time looked insane.)
2485
2486Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
2487(Addresses Debian bug #302200)
2488
2489Make the blkid library more paranoid about being run from setgid
2490programs, and to use __secure_getenv() from libc if it is available.
2491
2492Fixed spelling mistakes, typos, and otherwise clarified man pages.
2493(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593

2501Programmer's notes:
2502-------------------
2503
2504Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2505changed to take an unsigned int for the bit number. Negative bit
2506numbers were never allowed (and didn't make any sense), so this should
2507be a safe change. This is needed to allow safe use of block numbers
2508greater than or equal to 2**31.
2509
2510The compile_et program will avoid recreating generated foo_err.c and
2511foo_err.h files if no changes are necessary. The compile_et program
2512will also atomically replace these files to avoid a potential parallel
2513build race problem on SMP systems. (Addresses Sourceforge Bug:
2514#1157933)
2515
2516Added a new function to the blkid library, blkid_probe_all_new(),
2517which only probes newly added disk devices, and change
2518blkid_find_dev_with_tag() to use this function so that when a
2519requested tag is not found, devices that were previously not checked
2520are searched before searching all devices in the system.
2521
2522Added new functions to the blkid library, blkid_dev_set_search() and
2523blkid_dev_has_tag().
2524
2525E2fsck's problem strings can now use @m and @n as abbrevations for
2526"multiply-claimed" and "invalid", respectively.
2527
2528The e2fsprog.pot file now has an explanation of how the @-expansion
2529and %-expansion works, and strings in e2fsck/problem.c which contain @
2530characters now have comments in e2fsprogs.pot with the @-expansion to
2531make life easier for translators.
2532
2533Fixed missing return values in the ext2fs library which could cause it
2534to return random garbage in certain error conditions.
2535
2536Allow the current time to be overriden via the E2FSCK_TIME environment
2537variable for use in regression tests.
2538
2539The test scrpit driver program now exits with a non-zero status if
2540there any of its test that it ran failed.
2541
2542Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
2543Bug: #1157933)
2544
2545Fixed "make check" so that it compiles correctly even when e2fsprogs'
2546header files have not be installed in the system include directories.
2547(Addresses Sourceforge Bug: #1180572)
2548

Theodore Ts'ofd4b28e2005-03-21 22:37:03 -05002552E2fsprogs 1.37 (March 21, 2005)
2553===============================
2554
2555Add support for checking the validity of Extended Attributes stored in
2556inodes to e2fsck.
2557
2558Add support for dumping the contents of large inodes to debugfs,
2559including the extended attributes stored in inodes.
2560
2561Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
2562when we create a new inode we make sure that the extra information in
2563the inode (any extra fields in a large inode and any ea-in-inode
2564information) is initialized correctly. This can take place when
2565mke2fs creates the root and lost+found directory, when e2fsck creates
2566a new root inode or a new lost+found directory, and when the user uses
2567the debugfs write, mknod, or mkdir commands. Otherwise, the newly
2568create inode could inherit garbage (or old EA information) from a
2569previously deleted inode.
2570
2571Fixed a bug in e2fsck so it would notice if a file with an extended
2572attribute block was exactly 2**32 blocks, such that i_blocks wrapped
2573to zero.
2574
2575Added support to filefrag to detect files which are using the new
2576experimental file extents format, and use the non-ext2 algorithm in
2577that case. Fixed a bug to avoid reporting a false discontinuity if
2578there is one or more unallocated blocks at the beginning of a file.
2579
2580Duplicated a check for noticing whether or not the number of blocks
2581(given a certain blocksize) is greater than 2**32 when the
2582BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
2583allows mke2fs to automatically use a larger blocksize when creating a
2584filesystem on a very large device when run on systems that do not
2585support BLKGETSIZE64.
2586
2587Fix the I18N build which was broken in e2fsprogs 1.36 because the
2588build system had been switched to treat the .gmo files as shipped
2589files (for backwards compatibility with systems that have older GNU
2590I18N tools installed), but the gen_tarball.in script was still
2591removing the .gmo files from the official source distribution.
2592
2593Fixed various Debian packaging issues --- see debian/changelog for
2594details. (Addresses Debian Bugs ##296769, #299341)
2595
2596Programmer's notes:
2597-------------------
2598
2599Added new functions to the e2p library which convert between a string
2600and os_type: e2p_os2string() and e2p_string2os(), and used them to
2601make the generated binaries more compact.
2602
2603Fixed a compile-time error on Darwin systems.
2604
2605Cleaned up the lib/ext2fs Makefile slightly.
2606
2607
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002608E2fsprogs 1.36 (February 4, 2005)
2609=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002610
2611All of the patches that were applied to Fedore Core 3's
2612e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
2613lot of bug fixes first. Users of Fedora Core 3 are strongly
2614encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
2615
2616Add support for filesystem with the online resizing via resize inode
2617feature. Fixed numerous bugs from the Fedora patches. The Fedora
2618patches also didn't bother to do any consistency checking on the
2619resize inode, or add any tests to the regression test suite. The "-R
2620resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
2621being listed in mke2fs's usage message. All of these shortcomings
2622have been corrected.
2623
2624E2fsck can also also fix filesystems trashed by Fedora's resize2fs
2625program. In order to do this, the user must run the commands:
2626
Theodore Ts'od0a3b462005-05-05 22:57:44 -04002627 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002628 e2fsck -f /dev/hdXXX
2629
2630Optionally, the ext2prepare command can be used to re-enable online
2631resizing after the filesystem has been fixed.
2632
2633The fsck program will now accept an optional filedescriptor argument
2634to the -C option. (The Fedora version of this patch would sometimes
2635cause fsck to ignore a parameter on fsck's command line in some rare
2636cases, sigh.)
2637
Theodore Ts'odc256972005-01-26 13:20:12 -05002638Make sure e2fsprogs doesn't write garbage into the reserved portion of
2639large inodes.
2640
2641Make sure resize2fs releases the blocks belonging to the old inode
2642table blocks when moving the inode table. (Addresses Debian Bug:
2643#290894)
2644
2645Skip the r_resize_inode test if resize2fs is not compiled (due to
2646configure --disable-resizer)
2647
2648E2fsck now checks the summary filesystem accounting information, and
2649if any of the information is obviously wrong, it will force a full
2650filesystem check. (Addresses Debian Bug #291571)
2651
2652Fix e2fsck to not complain when the resize_inode feature is enabled,
2653s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
2654the resize inode.
2655
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002656Fix e2fsck to note delete symlinks that contain an extended attribute
2657after the ext_attr feature flag has been cleared. (Addresses Red Hat
2658Bugzilla #146284).
2659
Theodore Ts'odc256972005-01-26 13:20:12 -05002660Add new utility program, copy_sparse.c, which is very useful
2661for dealing with large sparse files (such as e2image files).
2662
2663Add support for jnl_blocks[] for debugfs's set_super_value.
2664
2665Fix filefrag so that it works correctly with sparse files.
2666
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002667Filefrag -v will print first and last blocks.
2668
Theodore Ts'odc256972005-01-26 13:20:12 -05002669Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
2670and dumpe2fs.
2671
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002672Add mke2fs support so that it can support filesystems larger than 4TB
2673automatically, by retrying with a 4k blocksize if the device size is
2674too big to be expressed using a 1k blocksize. (Addresses Sourceforge
2675bug #1106631)
2676
Theodore Ts'odc256972005-01-26 13:20:12 -05002677Change blkid to test for NTFS first because Windows sometimes doesn't
2678clear enough of the parition to confuse the probing routines into
2679thinking the old filesystem type is still valid. (Addresses Debian
2680Bug #291990)
2681
Theodore Ts'o66fa0de2005-01-11 14:39:55 -05002682Add support for swap partition label and uuid's in the blkid library.
2683
Theodore Ts'odc256972005-01-26 13:20:12 -05002684Add support to the blkid library to recognize Oracle ASM volumes.
2685
2686Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002687not just the first one, and work more consistently when the blkid
2688cache file is not available or set to /dev/null. (Addresses Debian
2689Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -05002690
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002691Badblocks will now correctly display block numbers greater than
2692999,999,999 in its progress display.
2693
2694The tune2fs program will not allow the user from setting a ridiculous
2695number of reserved blocks which would cause e2fsck to assume the
2696superblock was corrupt. E2fsck's standards for what is a ridiculous
2697number of reserved block has also been relaxed to 50% of the blocks in
2698the filesystem.
2699
2700The blkid library will return vfat in preference to msdos, and ext3 in
2701preference to ext2 (if the journalling flag is set) so that mount will
2702do the right thing. (Addresses Debian bug #287455)
2703
2704Mke2fs will now use the -E option for extended options; the old -R
2705(raid options) option is still accepted for backwards compatibility.
2706Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
2707
2708Mke2fs will now accept a size in megabytes, gigabytes, and other units
2709(via "32m" or "4g" on the command line) if the user finds this more
2710convenient than specifying a block count.
2711
2712Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
2713cache conherency problem.
2714
2715Debugfs now supports a new command, set_inode_field, which allows a
2716user to manually set a specific inode field more conveniently, as well
2717as set entries in the indirect block map.
2718
2719Debugfs's set_super_value command has been enhanced so that the user
2720can set most superblock fields, including the date/time fields and
2721some of the more newsly added superblock fields.
2722
2723E2fsprogs programs now accept an offset to be passed to the file
2724specifiers, via the syntax: "/tmp/test.img?offset=1024".
2725
2726E2fsprogs programs will now accept blocksizes up to 65536; kernel
2727support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002728other architectures with page sizes greater than 4k. There are 2.6
2729kernel patches out there which enable this, but they are of this
2730writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002731
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05002732The e2image command now takes the -s option which will scramble
2733directory entries for raw image files.
2734
2735Fix a file descriptor leak in the filefrag program.
2736
2737Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
2738present.
2739
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002740Fix bug in debugfs where kill_file would lead to errors when deleting
2741devices and symlinks. (Sourceforge Bugs #954741 and #957244)
2742
2743Fix bug in the blkid library when detecting the ocfs1 filesystem
2744
2745Remove obsolete EVMS 1.x and a.out DLL support.
2746
2747E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -04002748
2749Fixed two potential ordering constraint problems in e2fsck which might
2750cause the filesystem to be corrupted if e2fsck is interrupted during a
2751(extremely narrow) race window. Thanks to Junfeng Yang from the
2752Stanford Metacompilation group for pointing this out.
2753
2754Fixed bug in e2fsck where it would not accurately detect whether or
2755not the system is running on adaptor if the ACPI device representing
2756the AC adapter didn't correspond to the what was used on IBM
2757Thinkpads.
2758
2759Change e2fsck to accept directories greater than 32MB.
2760
2761Fix e2fsck so that a checkinterval of zero disables a time-based check
2762of the filesystem.
2763
2764Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
2765to the PAGER environment variable. (Addresses Debian Bug #239547)
2766
2767Tune2fs will not mark rewrite the superblock if the feature bitmasks
2768are not modified.
2769
2770The debugfs program will set the filetype information when creating a
2771link.
2772
2773Add debugfs -d option to use a separate source of data blocks when
2774reading from an e2image file.
2775
2776Add e2image -I option which allows the e2image metadata to be
2777installed into a filesystem.
2778
2779Fixed bug in the badblocks program which caused "done" to always
2780appear in english even when a translation was available. (Addresses
2781Debian Bug #252836)
2782
2783The blkid program has a new option -o which controls the output format
2784of the blkid program; this is makes blkid more convenient to use in
2785shell scripts.
2786
2787Fix a minor bug in uuid library, which was not using the full 14 bits
2788of clock sequence when generating UUID's.
2789
2790Fix a Y8.8888K problem in the uuid library.
2791
2792Logsave now creates a new session id for itself to avoid getting
2793killed by init whan transitioning between init levels.
2794
2795Change the licensing of the UUID library to be the 3-clause BSD-style
2796license; this allows Apple to use the uuid library in Darwin.
2797
2798Add ocfs and ocfs2 probe support into the blkid library.
2799
2800Fix a memory and file descriptor leak in the blkid library.
2801
2802The blkid library will revalidate the device if the system time is
2803earlier than last verification time of the device, since that
2804indicates that the system time is probably nottrustworthy.
2805
2806The blkid library will override the default location of the blkid.tab
2807file by the BLKID_FILE environment variable, if it is available.
2808
2809Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
2810
2811Add various portability fixes for lame new versions of glibc, Darwin
2812and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002813Bugs #239934, #264630, #269044, #255589, #289133)
2814
2815Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -04002816
2817Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -04002819
2820Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
2821
2822Update the rpm spec files so that it works better with Fedora core 2
2823and RH9.
2824
2825Fixed various Debian packaging issues (see debian/changelog). In
2826particular, fixed the Debian initrd scripts. (#241183, #248050,
2827#253595, #247775)

2830Programmer's notes:
2831-------------------
2832
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002833Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -04002834
2835The uuid library now has new functions uuid_unparse_upper() and
2836uuid_unparse_lower() which forces the case of the hex digits to be
2837upper case, or lower case.
2838
2839The build process has been speeded up by enhancing the subst program
2840to update the modtime on the generated files even when the generated
2841file hasn't changed.
2842
2843The uuid library now uses C99 stdint.h types instead of custom types.
2844
2845Updated config.guess and config.sub with newer versions from the FSF.
2846
2847Removed out of date .cvsignore files from the source distribution.
2848
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002849The ext2fs_unlink() function will return an error if both the name and
2850inode number are unspecified, to avoid doing something surprising
2851(such as unconditionally deleting the first directory entry).
2852Directory entries are now deleted by coalescing them with the previous
2853directory entry if possible, to avoid directory fragmentation. This
2854is not an issue with the e2fsprogs suite, but may be a problem for
2855some of the users of libext2fs, such as e2tools.
2856
2857Add support for version numbers of the form "1.36-rc1".
2858
Theodore Ts'o48301122004-09-19 08:23:41 -04002859Fix build of mke2fs.static.
2860
Theodore Ts'odc256972005-01-26 13:20:12 -05002861Add basic ext2fs library support for large (EA in inode) inodes.
2862
Theodore Ts'o48301122004-09-19 08:23:41 -04002863The test_io mechanism can now abort after n reads or writes to a
2864particular block. The block is specified by TEST_IO_BLOCK environment
2865variable, and the read/write count by the TEST_IO_READ_ABORT and
2866TEST_IO_WRITE_ABORT environment variables. The block data is now only
2867dumped if the 0x10 bit is set in TEST_IO_FLAGS.
2868
2869UUID_DEFINE() in the uuid library now creates a static variable, with
2870__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
2871be used in header files.
2872
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002873Add support for the install-strip and install-shlibs-strip targets, as
2874suggested by the GNU coding guielines. "make install" no longer
2875strips the binaries which are installed.
2876
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002877Remove support for the --enable-old-bitops configure option which was
2878only for very old sparc systems.
2879
2880Remove support for --enable-clear-htree; this was only needed during
2881the early development of the htree patch.
2882
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -05002883Use Linux-kernel-style makefile output so it is easier to see compiler
2884warnings.
2885
2886Update gettext files to version 0.14.1.
2887
2888Update to use autoconf 2.5x.
2889
2890Improved support for compiling e2fsprogs under dietlibc.
2891
Theodore Ts'o4ee558f2005-01-19 02:20:04 -05002892Make e2fsprogs portable to Solaris and FreeBSD systems.
2893
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -05002894Add blkid_verify(), blkid_get_library_version(), and
2895blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -05002896
2897Add pkg-config files for e2fsprogs's libraries.
2898
2899Fix "make uninstall" to so that it removes everything that is installed.
2900
Theodore Ts'o3eee5e92005-02-05 18:26:03 -05002901Add a configure --enable-maintainer-mode option which enables the
2902makefile rules to rebuild the configure script from configure.in, and
2903to reubuild the .gmo files in po directory.
2904
2905Drop the sparc assembly bitwise operations; it's less efficient
2906than the GCC 3.4 compile code and triggers compiler warnings on
2907sparc64. Thanks to Matthias Andree for his analysis and suggestions.

2912==================================
2913
Theodore Ts'o48301122004-09-19 08:23:41 -04002914E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -05002915preserves the existing badblocks list.
2916
Theodore Ts'o48301122004-09-19 08:23:41 -04002917Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.

2919E2fsprogs will now deal correctly with symlinks that contain
2920extended attribute information, which can be created using SE Linux.
2921(Addresses Debian Bug #232328)
2922
2923Remove a double longjump into an invalid stack frame bug in e2fsck.
2924(This was during an abort sequence, which normally worked on Linux and
2925caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002926
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002927Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
2928(the NLS library will replace "" with the .po header information).
2929
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002930Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
2931dump due to a division by zero error. (Addresses Debian bug #207082)
2932
Theodore Ts'o151a7162003-12-26 14:04:33 -05002933Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
2934when reconnecting a directory requires creating a lost+found
2935directory. (Addresses Debian bug #219640).
2936
2937Fixed a bug where e2fsck would bomb out if a journal needed to be
2938replayed when using an alternate superblock.
2939
Theodore Ts'o48301122004-09-19 08:23:41 -04002940E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002941if the laptop is running on battery. The next time fsck runs while
2942the system is on the AC mains, or after the grace period is exceeded,
2943the filesystem will be checked. (Addresses Debian bug #205177)
2944
2945E2fsck will inform the user when there are 5 or fewer mounts before a
2946filesystem check will be forced. (Addresses Debian bug #157194)
2947
2948Fix e2fsck's handling of corrupted indirect blocks in the bad block.
2949We now correctly handle the case where there is an overlap between a
2950block group descriptor or a superblock and a bad block indirect block.
2951In the case where the indirect block is corrupted, we now suggest
2952"e2fsck -c".
2953
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002954Fix byte swap bugs in e2fsck that caused the journal backup location
2955in the superblock and symlinks created by SE Linux to be cleared
2956by e2fsck on big-endian machines. (Addresses Debian bug #228723)
2957
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002958E2fsck -c now replaces the current list of bad blocks with the ones
2959found by badblocks.
2960
2961Fix bugs in e2fsck and tune2fs which could cause a core dump if a
2962non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
2963
2964Fix a potential bug in e2fsck which could cause it to core dump when
2965trying to print the location of the backup superblock.
2966
2967Protect against a potential core dump in e2fsck when printing a
2968message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04002969
Theodore Ts'o6826bde2003-08-21 02:14:44 -04002970Add support for backing up the journal inode location in the
2971superblock. E2fsck will automatically save the journal information in
2972the superblock if it is not there already, and will use it if the
2973journal inode appears to be corrupted. ext2fs_add_journal_inode()
2974will also save the backup information, so that new filesystems created
2975by mke2fs and filesystems that have journals added via tune2fs will
2976also have journal location written to the superblock as well.
2977Debugfs's logdump command has been enhanced so that it can use the
2978journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05002979
2980E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -04002981
2982Shrink the size of the e2fsck executable by moving some initialized
2983variables to the BSS segment.
2984
2985E2fsck will avoid printing the ^A and ^B characters which bracket the
2986progress bar when stdout and stdin are a tty device instead of a pipe
2987to another program. (Addresses Debian bug #204137)
2988
Theodore Ts'o151a7162003-12-26 14:04:33 -05002989Debugfs's mkdir command will automatically expand the directory if
2990necessary. (Addresses Debian Bug: #217892)
2991
2992Fixed a bug in debugfs so that copying a file from /dev/null uses the
2993correct mode bits. (Addresses Debian Bug: #217456)
2994
2995If the environment variables DEBUFS_PAGER and PAGER are not set,
2996debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -05002997/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -05002998(Addresses Debian bug #221977)
2999
Theodore Ts'ob70b1162004-02-28 10:52:35 -05003000Debugfs will now support 2.6 device numbers where the major or minor
3001number may be larger than 255. (Addresses Sourceforge bug #865289)
3002
Theodore Ts'o48301122004-09-19 08:23:41 -04003003Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
3004
Theodore Ts'o1daf7582004-01-31 22:33:16 -05003005Chattr now stops processing options when it sees '--'. (Addresses
3006Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -05003007
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003008Fix regression tests so they work correctly when e2fsprogs is compiled
3009with configure --disable-htree.
3010
Theodore Ts'o1daf7582004-01-31 22:33:16 -05003011Fix bug in uuid library when there is no network card and the library
3012is generating a time-based uuid. The random MAC address was not
3013correctly generated to be a multicast address.
3014
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003015Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -04003016around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003017
3018Fix bug in badblocks when using O_DIRECT; we need to make sure that
3019we're reading from an offset which is page aligned. For read-only and
3020read-write tests, we try to recover after an error so that we can
3021continue reading on page-aligned boundaries. (Addresses Debian Bug
3022#203713)
3023
Theodore Ts'ob70b1162004-02-28 10:52:35 -05003024Badblocks now checks 64 blocks at a time instead of 16. (Addresses
3025Debian bug #232240)
3026
Theodore Ts'o151a7162003-12-26 14:04:33 -05003027Updated and clarified various man pages. (Addresses Debian Bug
Theodore Ts'ob70b1162004-02-28 10:52:35 -05003028#206845, #222606, #214920, #232406)

Theodore Ts'o151a7162003-12-26 14:04:33 -05003030Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
Theodore Ts'o6826bde2003-08-21 02:14:44 -04003031
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003032Fixed various Debian packaging issues (see debian/changelog).
3033
3034Programmer's notes:
3035-------------------
3036
Theodore Ts'ob70b1162004-02-28 10:52:35 -05003037Fixed a build problem so that e2fsprogs would compile with the
3038--enable-profile option to configure selected. (Addresses Sourceforge
3039bug #811408)
3040
3041Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
3042Bugzilla Bug #112448)
3043
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05003044Centralize code which calculates the location of the superblock
3045and block group descriptors so that it is in a single library routine.
3046
Theodore Ts'o6826bde2003-08-21 02:14:44 -04003047Added two new functions, ext2fs_file_open2() and
3048ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3049
3050Fix compile_et to output the correct prototype for
3051initialize_xxx_err_table_r() in the header file. (Addresses Debian
3052bug #204332)
3053
3054In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3055
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003056Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3057present. This is for when we try stuffing an int into void * pointer.
3058
3059Fix type-punning which can cause gcc 3.x to miscompile code by getting
3060confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3061and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3062**'. The EVMS code uses an ugly union approach since we don't want to
3063modify the EVMS interfaces.
3064
3065Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3066aid build process on systems can use invoke GNU make as "gmake".
3067
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05003068Added regression testing for mke2fs.
3069
3070Fixed gcc -Wall nitpicks.
3071
Theodore Ts'o1daf7582004-01-31 22:33:16 -05003072Fixed various compiler warnings.
3073
3074Add portability fixes for FreeBSD and for using fsctl under Darwin to
3075support ext2 ioctl's.
3076
Theodore Ts'o858dd7b2003-08-02 20:48:35 -04003077
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003078E2fsprogs 1.34 (July 25, 2003)
3079===============================
3080
3081Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3082a tight loop while waiting for a child fsck to exit in some cases.
3083This burns CPU times which slows down the low-level filesystem check.
3084
3085Added code to mke2fs to assure that the default block size for a
3086filesystem is at least as big as the sector size of the device, if it
3087can be determined.
3088
3089Changed mke2fs and resize2fs to round the default size of a filesystem
3090to be an even multiple of the VM pagesize in order to avoid a Linux
3091kernel bug introduced when the storage of the buffer cache was moved
3092into the page cache.
3093
3094Mke2fs will warn the user when creating a filesystem with journaling
3095and a blocksize greater than 4096. (Addresses Debian bug #193773)
3096
3097Fixed a bug in resize2fs which caused it to fail on filesystems with a
3098non-empty bad block list. Resize2fs now discards any blocks on the
3099badblock list which are no longer part of the filesystem as the result
3100of a filesystem shrink. (Note: this means that shrinking and then
3101enlarging a filesystem is no longer a reversible operation;
3102information about bad blocks in the part of the filesystem which is to
3103be chopped off will be lost.)
3104
3105Changed resize2fs so the user can use prefixes to specify the units of
3106the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3107and to make the error and informational messages explicitly display
3108the blocksize used by the filesystem, in order to avoid confusion.
3109(Addresses Debian bug: #189814)
3110
3111Added a new debugfs command, dump_unused, which dumps the contents of
3112all unused blocks to stdout. (Useful as an emergency try-to-find
3113deleted data command.)
3114
3115Added a new debugfs command, imap, which prints the location of a
3116specified inode in the inode table.
3117
3118Fixed a bug in the badblocks program which caused it to use one bit of
3119randomness in its non-destructive read/write test, instead of using a
3120full 8 bits of randomness.
3121
3122Added a new option (-t) to badblocks, which allows the user to control
3123the test pattern(s) used when checking a disk.
3124
3125The blkid probe function now more correctly detects UDF filesystems.
3126
3127Fixed a bug in the blkid library which caused it to not update its
3128cache if a filesystem changes from having a label to not having a
3129label.
3130
3131Fixed a bug in the blkid library wihch could avoid an infinite loop
3132in blkid_find_dev_with_tag() if /proc is not mounted and there the
3133/etc/blkid.tab file has not yet been created.
3134
3135Fixed the badblocks program so that the destructive read/write test
3136honors the -c option, and to use O_DIRECT when possible to avoid
3137thrashing the system block buffer cache.
3138
3139Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -04003140 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003141 - Removed testing NYC translation
3142 - Fixed NLS support for message abbrevations in e2fsck
3143 - Remove de-utf.po, since we shouldn't have two versions using different
3144 charset encodings.
3145 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3146 simplify the statistics reporting in e2fsck.
3147
3148Changed configure.in so that its defaults for *BSD systems no longer
3149build an fsck wrapper, and not to install in /usr/local by default.
3150
3151Fixed some minor spelling errors/typo's in e2fsck and the configure
3152script.
3153
3154Fixed various Debian packaging issues (see debian/changelog).
3155
3156Updated and clarified man pages. (Addresses Debian Bug #195616)
3157
3158Programmer's notes:
3159-------------------
3160
3161Fix gcc -Wall nitpicks.
3162
3163Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3164NLS support by default. (Added partial workaround for gettext/Darwin
3165incompatibility problems.)
3166
3167Added full MIT KRB5 and Himdall compaibility support to the com_err
3168library and the compile_et program. (Addresses Debian bug #191900)
3169
3170Added the blkid_known_fstype() function to the blkid library, which
3171returns true if it is passed a filesystem type which is recognized by
3172the blkid probing functions.
3173
3174Improved the documentation for the blkid library.
3175
3176Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3177returns the hardware sector size of a device, if it is available.
3178
3179Added a dependency in the blkid library's .so file to the uuid
3180library, since the former uses the latter. (Addresses Debian bug
3181#194094)
3182
3183Added --with-diet-libc and --disable-evms to the configure script.
3184
3185Fixed a minor memory leak in the badblocks program.
3186
3187Fixed a portability problem in tune2fs --- not all systems have strptime().
3188
3189Fixed a portability problem in debugfs with the use of getopt() more
3190than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3191things differently.
3192
3193Add support Windows support to ext2fs_get_device_size().
3194
3195Added (normally disabled) debugging code to the Unix I/O manager which
3196causes it to disable all userspace caching if the NO_IO_CACHE is
3197defined.
3198
3199Changed the test I/O manager so it can always be linked into e2fsck,
3200mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3201configure script. The test I/O manager will only print any debugging
3202information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3203variables are set, which specifies which I/O operations are logged and
3204a block number to watch, respectively. The log messages are sent to
3205stderr by default, unless a filename is specified via the
3206TEST_IO_LOGFILE environment variable.
3207
3208
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04003209E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003210===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003211
Theodore Ts'oba142c12003-04-16 00:59:59 -04003212Added a new utility program, logsave, which captures the output of a
3213command in a log file, even if the containing directory hasn't been
3214mounted yet (in which case the it saves the output in memory until it
3215can write out the logfile). This is useful for capturing the
3216output of fsck during the boot sequence.
3217
3218Fixed some portability problems that were causing problems under
3219the Cygwin32 environment.
3220
3221Mke2fs now interprets a negative number to the -b option as a minimum
3222block size.
3223
3224Fixed a bug in mke2fs which was incorrectly checking the argument to
3225the -g option if the default block size was used. (Addresses Debian
3226bug #188319)
3227
3228Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3229it can not find filesystem checkers for jfs, reseirfs, and xfs.
3230
3231E2fsck now updates the global free block and inode counters from the
3232block group specific counters quietly. This is needed for an
3233experimental patch which eliminates locking the entire filesystem when
3234allocating blocks or inodes; if the filesystem is not unmounted
3235cleanly, the global counts may not be accurate.
3236
3237Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
32382.0 is not yet supported; this only pulled in the bug fixes: fixed
3239possible hangs caused by bugs in calling waitpid, and not setting the
3240pipe to non-blocking mode; also fixed a file descriptor leak; made
3241sure all functions call log entry/exit functions.)
3242
3243Badblocks now flushes its output file as bad blocks are discovered.
3244
3245The uuid library is now more paranoid about assuming the correctness
3246of the /dev/random device; it mixes in a stream of bytes from
3247random/srandom, just in case.
3248
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003249Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04003250maintainer of e2fsprogs. Other various Debian-specific packaging
3251cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003252
3253Move the source tarball generation functions from the top-level
3254makefile to the util/gen-tarball script.
3255
3256Updated the Turkish .po translation file.
3257
Theodore Ts'o1daf7582004-01-31 22:33:16 -05003258Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05003259it more compatible with com_err libraries from those distributions.
3260
3261Changed dumpe2fs to always display the superblock fields relating to
3262the journalling and/or directory indexing feature even if those
3263features are not enabled.
3264
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003265Updated and clarify copyright statement vis-a-vis alpha releases of
3266e2fsprogs.
3267
3268The ss library will now try to dynamically link to the readline
3269library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04003270the debugfs program now has line editing and history features. The
3271SS_READLINE_PATH environment variable is used to find a readline or
3272readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003273
Theodore Ts'oe5dced72003-03-15 04:28:17 -05003274E2fsck now finds most duplicate filenames (all when rebuilding all
3275directories via the -D option) and offers to delete or rename
3276duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3277
3278Fix bug in e2image. When writing out a raw image file, include data
3279blocks from symlinks that do not store the symlink within the inode.
3280
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003281Fix bug in resize2fs which incorrectly moved the block and inode
3282bitmaps for sparse superblock filesystems and incorrectly marked
3283blocks as in use. (Addresses Debian bug #174766)
3284
3285Added a new shared library, the blkid library, which efficiently
3286allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3287and UUID filesystem specifiers without needing to search all of the
3288devices in the system. Instead, the device is looked up in a cache
3289file, and then verified to make sure the blkid cache is correct.
3290
3291Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3292the device name, using the blkid library. (Addresses Debian bugs
3293#166048, #179671)
3294
3295Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3296used for spaces in device labels.
3297
3298Removed 32-bit limitations for debugfs's dump command.
3299
3300If the user specifies a large number of inodes, Mke2fs will
3301automatically adjust the number of blocks per group to find a valid
3302set of filesystem parameters.
3303
3304Add workaround to detect broken MD devices where when some of the
3305underlying devices are marked read-only, writes to the MD device are
3306silently dropped. E2fsck will detect if there is an attempt to run
3307the journal twice, and abort with an error if this is the case.

3309
3310E2fsck will print an error if more than one of the -p/-a, -n or -y
3311options are specified.
3312
3313E2fsck will fix HTREE corruptions in preen mode, without stopping the
3314boot process. This is needed because the 2.4 ext2 filesystem
3315accidentally had the INDEX_FL backwards compatibility code removed.
3316
3317Mke2fs no longer creates filesystems with the dir_index flag set by
3318default; the user has to specifically request it.
3319
3320Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04003321#173612, #175233, #175113, and #170497, #185945, #188318)

Theodore Ts'o3809bf12003-03-07 01:09:57 -05003325Programmer's notes:
3326-------------------
3327
3328Fix various gcc -Wall nits.
3329
3330Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05003331successfully under Solaris and Apple/Darwin.
3332
3333Fixed a Makefile dependency to allow building e2fsprogs using parallel
3334make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003335
3336Changes to create a subset distribution which consists only of the
3337et, ss, uuid, and blkid libraries. The configure script and top-level
3338makefile were changed to support working with a subset distribution.
3339
Theodore Ts'oba142c12003-04-16 00:59:59 -04003340Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3341actually used, and might people who are looking for
3342EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3343
Theodore Ts'o508d7f32003-03-16 20:41:04 -05003344Updated debian files to fix a number of Lintian warnings.
3345
3346Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05003347
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04003348Removed unnecessary libraries from being linked into the fsck, lsattr,
3349chattr, and blkid executables.

Theodore Ts'o38513012002-11-09 15:00:56 -05003351E2fsprogs 1.32 (Nomvember 9, 2002)
3352==================================
3353
3354Fixed a bug in the Unix I/O routines which caused needless writebacks
3355of clean blocks from the unix_io cache (they were erroneously marked
3356as being dirty, so they were getting written back to disk before
3357getting evicted from the disk cache). This was harmless, but it
3358significantly slowed down e2fsck.
3359
3360Made some other minor optimizations to the Unix I/O routines to save a
3361small amount of CPU time.
3362
3363Updated internationalization files.
3364

Theodore Ts'oae65b292002-11-08 20:08:48 -05003366E2fsprogs 1.31 (Nomvember 8, 2002)
3367==================================
3368
3369Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3370compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3371handling for child process that die unexpectly. Add a hack to force
3372mkfs to create filesystems that won't cause problems with hardware
3373that has 2k or 4k minimum blocksize requirements. Read from child
3374processes in non-blocking mode, so that the GUI continues to update.
3375
3376Fix e2fsck so that it returns the appropriate exit code when the root
3377filesystem has been changed, so that system's rc scripts will be told that
3378the system needs to be rebooted.
3379
3380Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3381was set, some of the descriptor blocks that should have been written
3382out were getting skipped.
3383
3384Changed e2fsck to force out changes to the backup copies of the
3385superblock and block group descriptors when important changes are made
3386to those data structures.
3387
3388Fix a bug where e2fsck could erroneously mark a filesystem as being
3389clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3390introduced in e2fsprogs 1.28.)
3391
3392If journal debuging is enabled using --enable-jbd-debug, the debugging
3393level is now set via the E2FSCK_JBD_DEBUG environment variable.
3394
3395If byteswapping support is disabled using configure --disable-swapfs,
3396skip the tests which depend on byte-swapping, so that "make check"
3397won't bomb out.
3398
3399Lshattr will now display the indexed directory flag. Also, some of
3400the more esoteric compression flags are supressed unless compression
3401support has been enabled.
3402
3403Update man pages.
3404
3405
Theodore Ts'o5d823a42002-11-01 02:13:53 -05003406E2fsprogs 1.30 (October 31, 2002)
3407=================================
3408
3409When resizing a filesystem, and inodes need to moved, resize2fs will
3410update the inode's ctime field, and the mtime field of the containing
3411directories, so that incremental backups using dump/restore will work
3412correctly.
3413
3414In order to avoid spurious errors, e2fsck wil check the last
3415superblock write time to determine whether or not it can safely use
3416the LOW_DTIME checks to determine if there are inodes on the orphan
3417inode linked list that had somehow gotten disconnected. (Addresses
3418Sourceforge bug #620980)
3419
3420Partition in /proc/partitions that being with the string "lvm" are
3421considered real partitions even if they do not end with a number.
3422
3423Fixed a bug in the the uuid generation function, where if /dev/urandom
3424is not present, but /dev/random is, and there isn't sufficient
3425entropy, the get_random_byte function could spin a loop forever.
3426
3427E2fsck, mke2fs, etc. will now reliably notice when image files are
3428mounted using the loopback interface. (Addresses Sourceforge bug
3429#619119)
3430
3431When flushing buffers (as is done by badblocks, for example) check to
3432see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3433FDFLUSH ioctl which causes the MD device driver which causes confusing
3434syslog messages about obselete ioctl messages. (Addresses Sourceforge
3435bug #545832).
3436
3437Debugfs's write command now checks to see if the destination filename
3438exists before creating it. (Addresses Sourceforge bug #478195.)
3439
3440When installing man pages, search for compressed man pages using all
3441commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3442
3443Fixed a bug in fsck where multiple filesystems specified on the
3444command were not being checked in parallel due to a logic bug
3445introduced to support the FSCK_MAX_INST environment variable.
3446
3447We have added a new superblock field, s_mkfs_time, which indicates
3448when a filesystem was created. It is set via mke2fs, and printed out
3449by dumpe2fs, but is not actually touched by the kernel.
3450
3451Dumpe2fs has been made more robust by not aborting if there is an
3452error reading the block/inode bitmaps; instead it will still print out
3453the location of the block/inode bitmaps and inode table.
3454
3455Add support for the an alternative block group descriptor layout which
3456allows for on-line resizing without needing to prepare the filesystem
3457in advance. (This is the incomat feature flag meta_bg.)
3458
3459Add support for storing default mount options in the superblock, so
3460that the filesystem can be mounted with specific mount options without
3461needing to specify them on the mount command line or in the /etc/fstab
3462file.
3463
3464Add support for a new inode flag, which is to be used for indicating
3465the top of directory hierarchies for the Orlov block allocator.
3466
3467Fix e2fsck so that if it creates the lost+found directory, it does so
3468with the more apporpriate permissions of 0700. Also change
3469mklost+found so that it also creates the directory 0700.
3470
3471Fixed format bug in e2fsck if NLS is in use.
3472
3473Add a German translation for e2fsprogs's NLS support.
3474
3475Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3476the beginning of the inode table. This won't matter much, since if
3477there is a bad block at the beginning of the inode table, the root
3478directory won't be available. But at least e2fsck won't crash in this
3479case.
3480
3481Fixed endian problems in the htree code for e2fsck and debugfs.
3482
3483When byte-swapping a filesystem on a PPC architecture, byte-swap the
3484bitmaps since the historical big-endian ext2 variant had byte-swapped
3485bitmaps, and the ext2fs library assumes this. This fixes the
3486regression test suite on PPC machines.
3487
3488Fix e2image so that it handles a bad block in the inode table
3489appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04003490
3491E2fsck now uses a more sophisticated algorithm to salvage corrupted
3492directories that recovers more information in the corrupted directory
3493block.
3494
3495E2fsck now performs additional consistency checks on indexed (HTREE)
3496directories.
3497
3498Fix bug where efsck might get confused about whether a completely
3499empty directory block is an empty leaf block or an interior htree
3500node. This could cause e2fsck to get confused into think that a valid
3501indexed directory was corrupted.
3502
3503E2fsck no longer creates an empty directory entry at the end of a
3504directory block when optimizing a directory. This would cause some
3505earlier versions of the dxdir kernel code to corrupt the directory
3506when attempting to split a node containing an empty directory entry.
3507
3508E2fsck could sometimes in rare circumstances leave the indexed flag
3509set after a small directory was optimized by compressing it instead of
3510indexing it. (This should never happen in real life, since
3511directories that small wouldn't have been indexed, but better safe
3512than sorry.)
3513
3514E2fsck now only updates the master superblock in all cases. This
3515slightly shortens its run time.
3516
3517Ext2ed can deal with directory entries of length 0; previously it
3518would get stuck in an infinite loop.
3519
3520Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3521specifiers. (Sourceforge patch #613447)
3522
3523Badblocks will now work correctly on read-only devices such as
3524CD-ROM's. (Sourceforge patch #600451)
3525
Theodore Ts'o5d823a42002-11-01 02:13:53 -05003526Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04003529E2fsprogs 1.29 (September 24, 2002)
3530===================================
3531
3532Fixed a bug in e2fsck which could corrupt a directory when optimizing
3533it (via the -D option) or rebuiliding the hash tree index with a 1 in
3534512 probability, due to a fence post error.
3535
3536Fixed a bug in the LVM support code which caused LABEL='xxx' not to
3537work correctly.
3538
3539Mke2fs now enables the directory indexing flag by default. (Since
3540this is a compatible feature flag, it's safe to do so.)
3541
3542Tune2fs will support setting the directory indexing feature flag. It
3543will automatically set up the default hash algorithm and hash seed
3544fields in the superblock.
3545
3546If the bone-headed user enters the root filesystem twice in
3547/etc/fstab, the -R option which skips the root filesystem will skip
3548all of them. (Addresses Debian bug #159423). Note! This is not a
3549precedent for dealing intelligently with any other kind of doubled
3550entry in /etc/fstab!
3551
3552
3553Programmer's notes:
3554-------------------
3555
3556Removed perror declaration in lib/et/internal.h. All modern systems
3557can be expected to define perror() these days. Besides, the lib/et
3558code wasn't using perror at all anyway. :-)
3559

Theodore Ts'ob7bad612002-08-31 03:00:33 -04003561E2fsprogs 1.28 (August 31, 2002)
3562================================
3563
3564Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
3565for setting the htree flag is not included yet, although it can be
3566manually turned on via the debugfs program.
3567
3568Clarified e2fsck error message which is printed when it cannot find
3569sufficient contiguous block when relcating filesystem metadata.
3570
3571Added support for building an EVMS plugin module for ext2/3. This
3572module is substantially the same as the EVMS module shipping with EVMS
35731.1, with one or two bugfixes. E2fsprogs can also build this plugin
3574for use with EVMS 1.0 (which did not include the ext2 plugin module),
3575if the configure --enable-old-evms flag is given.
3576
3577Fsck will search through EVMS volumes when trying to resolve
3578filesystem specifications such as LABEL=xxx or UUID=xxx.
3579
3580Added a new utility program, /sbin/findfs, which will return
3581filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
3582the device name.
3583
3584Update and clarified various man pages. (addresses Debian Bug #145044,
3585#146437, #131350, #151990, #144621, #141938)
3586
3587If there are no filesystems specified on fsck's command line, fsck now
3588treat that as if the -As options were given. Previously it would
3589simply do nothing. (Addresses Debian Bug #153102)
3590
3591Mke2fs no longer treats a failure to be able to clear the MD signature
3592at the end of the filesystem as a fatal error. (Addresses Debian Bug
3593#155007)
3594
3595The e2p library functions (which are used by lsattr and chattr) now
3596double check to make sure the file is a regular file or directory
3597before attempting to use the ext2 ioctls. Some device drivers
3598unfortunately respond to the ext2 ioctl's with unknown behaviour.
3599(Addresses Debian Bug #152029).
3600
3601The extended attribute handling has been updated to correspond with
3602the latest V2 bestbits ACL code.
3603
3604Fixed bug in e2fsck which caused it to not clear the dtime field when
3605processing truncated inodes on the orphan list. This could cause data
3606loss(!) if a filesystem is rebooted before a truncate has been
3607committed.
3608
3609E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
3610algorithms. This makes e2fsck much faster in the case of severely
3611corrupted filesystems where a large number of blocks are claimed by a
3612large number of inodes. (Thanks to the 2.5 IDE device driver for
3613inspiring this work.)
3614
3615Resize2fs has been significantly sped up when shrinking and expanding
3616a filesystem by a very small number of blocks (for example, when EVMS
3617is converting a partition to be an EVMS legacy volume).
3618
3619Added a new option to e2fsck, -D, which will optimize or compress all
3620of the directories in the filesystem.
3621
3622E2fsck now catches SIGINT and SIGTERM to make sure it will can
3623properly clean up and only exit at safe points. Fsck will pass
3624SIGINT/SIGTERM to its child processes, and wait until they have all
3625exited before it exits.
3626
3627The uuid parsing code in the uuid library now properly complains when
3628an illegally formated uuid is presented to it. (Addresses Debian bug
3629#152891)
3630
3631Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
3632and 2.4.17, since the workaround can cause problems when using a 2.4
3633kernel with an old version of glibc built with the 2.2 headers.
3634
3635Fixed a bug in mke2fs where it wasn't properly clearing the initial
3636superblock used by other filesystems. (Addresses Debian bug #147256.)
3637
3638Added support for the synchronous directory feature written by Andrew
3639Morton.
3640
3641The debugfs program can delete directories using the rmdir command.
3642
3643Add support for 8k and 16k filesystems (for systems with page sizes
3644that are greater or equal to 8k or 16k, respectively). Note that
3645these filesystems can not be mounted on x86 systems, or other systems
3646with only 4k page sizes, due to limitations in the current Linux VM
3647code.
3648
3649Resize2fs requires that the filesystem state be valid and have no
3650errors; otherwise, e2fsck -f must be run first. (Previously it simply
3651required that the last fsck time be greater than the last mount time.)
3652
3653Configure now defaults the man pages directory to /usr/share/man on
3654Linux systems.
3655
3656E2fsck now offers to truncate inodes which contain too many blocks (so
3657that i_blocks would overflow. Also fixed handling of large sparse
3658files.
3659
3660E2fsck now more completely checks for symlink validity, including
3661requiring NULL termination and length checks.
3662
3663E2fsck will offer to try forcing a disk write to remap a bad block
3664after finding a read error when reading a filesystem metadata block.
3665
3666Fixed a bug in debugfs which caused the -b and -s options to crash
3667debugfs, as well as breaking the testb, setb, and clearb functions.
3668
3669Added a bmap command to debugfs which calculates the logical to
3670physical block mapping for a particular inode.
3671
3672Fixed a bug in code which checked to see if a device was mounted which
3673sometimes (rarely) failed in the case of a plain file.
3674
3675Fixed a bug in resize2fs where when it reported an error, it would
3676print a message erroneously indicating that the filesystem had been
3677resized before it aborted.
3678
3679When resizing a plain file which is smaller than the requested size,
3680resize2fs will attempt to extended the file so that programs like
3681e2fsck will not complain that the file is too small.
3682
3683Resize2fs will print the actual new size of the filesystem when it is
3684finished resizing.
3685
3686Fixed a bug in debugfs where "ls -l" would report incorrectl file type
3687information on big-endian systems.
3688
3689
3690Programmer's notes:
3691-------------------
3692
3693Fixed collisions with C++ reserved words.
3694
3695Added portability fixes for building e2fsprogs on the HURD and AIX.
3696
3697Added the ext2ed program for creation of test cases. (ext2ed has many
3698limitations and bugs which make it unsuitable for production use.)
3699
3700The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
3701flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
3702name_len field is byte swampped on big-endian machines, since in the
3703V2 structure, name_len is a char field which is doesn't need to be
3704byte swapped --- except if an old-style kernel had byte-swapped the
3705name_len field as part of the V1 structure.

3709==============================
3710
3711The warning messages for mke2fs now go to standard error.
3712
3713Fixed to make sure "make check" runs all of the test programs with
3714LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
3715
3716The mke2fs program checks the boot sector for the BSD disk label, and
3717avoids erasing it if it is there.
3718
3719Fixed a bug in e2fsck which caused it to core dump if the journal
3720inode was missing when it was supposed to be there.
3721
3722E2fsck now prints ranges in pass 5 when printing deltas for the block
3723and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003724
3725Debugfs's "ls -l" command now will print out the file type information
3726in the directory entry.
3727
3728Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
3729mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
3730
3731Debugfs can now examine the experimental directory indexing
3732information.
3733
Theodore Ts'oa471ac52002-03-05 03:37:06 -05003734Fixed bug in debugfs which caused it to core dump if modify_inode is
3735called without an open filesystem.
3736
3737The debugfs lsdel command now runs its output through a pager first.
3738
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003739When installing manual pages, remove the compressed manual pages first.
3740
3741Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
3742
3743Fix the 2.4 resource limitation workaround introduced in 1.26 which
3744actually broke things on mips32, sparc32, and Alpha platforms.
3745
Theodore Ts'oa471ac52002-03-05 03:37:06 -05003746Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
3747(which is required by the newer libintl libraries).

Theodore Ts'oafa14ba2002-03-05 03:31:06 -05003754Fixed a few memory leaks in the e2fsck journaling code, and in the
3755ismounted code checking for a swap device.
3756
3757Add new inode I/O abstraction interface which exports an inode as
3758an I/O object.
3759
3760Exported ext2_file_flush as a public interface.
3761
3762In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
3763
3764Lots of small random portability fixes to make e2fsprogs build under
3765AIX --- even without the 5L compatibility toolkit, and even using the
3766uber-crippled AIX native C compiler.
3767
3768
Theodore Ts'o06987392002-02-03 01:36:54 -05003769E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003770=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003771
Theodore Ts'o446314f2001-12-24 15:22:27 -05003772Dumpe2fs will keep going now if the bad block inode can't be read.
3773(Previously it stopped with a fatal error.)
3774
3775E2fsck will now give an opportunity to run the journal even if the
3776recovery flag is not set. This is the default behaviour if e2fsck is
3777using a backup superblock, since the needs_recovery flag will never be
3778set in the backup superblock copies.
3779
3780E2fsck now automatically finds the backup superblock/group descriptors
3781even when the primary superblock is completely destroyed for 2k and 4k
3782filesystems. (Previously it just guessed/assumed that we were dealing
3783with a 1k filesystem in that case, and users had to manually specify
3784the backup superblock number.)
3785
3786Fixed a bug in e2fsck where it dereferences a null pointer when there
3787is a problem opening a filesystem in preen mode.
3788
3789E2fsck now handles external journals correctly; previously it trashed
3790the external journal device if the journal needed to be replayed.
3791
3792Work around ulimit incompatibility problem caused by recent 2.4
3793kernels; the unix IO module will automatically try to set any resource
3794limits to be infinite on startup.
3795
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003796Fixed a bug in e2fsck where it wasn't allocating a new block or inode
3797bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04003798 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003799
3800E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
3801clearing the new V2 fields if they do not make sense or if the ext3
3802superblock is version 1 superblock.
3803
3804E2fsck will automatically relocate the ext3 journal from a visible
3805file (i.e., /.journal) to an hidden inode if the filesystem has been
3806opened read/write. This allows the users to add a journal while the
3807filesystem is mounted, but the next time the system is rebooted, the
3808journal file will disappear. This avoids problems with backups,
3809stupid operators with superuser bits, etc.
3810
3811Fix a bug in fsck where it would not support a filesystem type of
3812"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
3813
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003814Fsck now supports fstab entries of the form "ext3,ext2". It will also
3815automatically identify reiserfs filesystems.
3816
3817The number of processes spawned by fsck can now be limited using the
3818FSCK_MAX_INST environment variable.
3819
Theodore Ts'o446314f2001-12-24 15:22:27 -05003820Fsck now searchs the LVM proc hierarchy to find logical volumes which
3821should be searched for UUID and label information.
3822
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003823Work around a bug in 2.4.10+ kernels by trying to unset the filesize
3824limit if at all possible, when opening a block device. (The filesize
3825limit shouldn't be applied against writes to a block device.)
3826
Theodore Ts'o446314f2001-12-24 15:22:27 -05003827In mke2fs and e2fsck, specifying the -c option twice will now do
3828a read/write test on the disk. Update the man pages to encourage
3829using the -c option, and to discouraging running badblocks separately,
3830since users tend to forget to set the blocksize when running
3831badblocks.
3832
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003833Mke2fs now automatically clears the immutable attribute on a
3834pre-existing .journal file left over from a previous failed attempt to
3835add a journal to an alreadyy-mounted filesystem.
3836
3837Fixed mke2fs's exit codes to consistently indicate when the mke2fs
3838operation failed.
3839
Theodore Ts'o446314f2001-12-24 15:22:27 -05003840Mke2fs now creates the lost+found directory with permissions of 0700,
3841so that files that had previously lived in protected directory are
3842safe if they get dropped in lost+found and the system administrator
3843doesn't deal with immediately. (Addresses Debian #bug 118443)
3844
3845Mke2fs and e2fsck (and all programs that use the
3846ext2fs_check_if_mounted function) will now properly identify that a
3847device is mounted, even in cases where devfs has confused things with
3848multiple devices names with the same identity, or if a dim-witted
3849system administrator has done something stupid like creating device
3850file aliases in their home directory. Also now checks for swap devices
3851by using /proc/swaps. (Addresses Debian bug #106622)
3852
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003853Added a new option (-T) to tune2fs which sets the time a filesystem
3854was last checked.
3855
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003856Speed up e2image when creating sparse raw image files by optimizing
3857away excess lseek() system calls.
3858
3859Fix support of large (> 2GB) files when used as a filesystem in
3860mke2fs, tune2fs, debugfs, and findsuper.
3861
3862Debugfs's stat and icheck commands now properly deals with large (>
38632GB) files.
3864
3865Debugfs's set_super_value command now prints out the list of valid
3866superblock fields which can be set using the command.
3867
Theodore Ts'o446314f2001-12-24 15:22:27 -05003868Debugfs's rm and kill_file command now updates the superblock free block
3869and inode counts, thus keeping the filesystem consistent.
3870
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003871Debugfs's lsdel command now takes an optional argument which allows
3872the user to only see the most recently deleted files.
3873
3874A new command (undel) was added to debugfs which automates
3875undeleting a deleted inode and linking it back to a directory.
3876
3877Debugfs's ls command now takes a new option, -d, which lists
3878deleted directory entries.
3879
3880Debugfs's testb, freeb, setb, and find_free_block commands now take an
3881optional count argument.
3882
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003883Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
3884be used to signal that a particular inode should not be eligible for
3885tail-merging --- this is needed for programs like LILO.
3886
3887The findsuper (an unreleased, uninstalled utility program) has been
3888improved to add extra validity checks and to add a progress meter.
3889(It is still an unsupported program; the officially supported way to
3890recover from a trashed partition table is to use gpart; findsuper is
3891for wizards only. :-)
3892
3893Debugfs was fixed to compile with "configure --disable-swapfs".
3894
Theodore Ts'o446314f2001-12-24 15:22:27 -05003895Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05003896
3897Added new translation file for Turkish.
3898
Theodore Ts'o446314f2001-12-24 15:22:27 -05003899Programmer's notes:
3900-------------------
3901
3902Fix general gcc -Wall complaints.
3903
3904E2fsprogs (mostly) works with the dietlibc.
3905
3906The programming texinfo file has been expanded to include description
3907of additional libext2fs functions. (Still not compeltely done, but a
3908lot of the more important functions have been documented.)
3909
3910Added a umask structure to struct_ext2_filsys, which currently only
3911modifies the behaviour of ext2fs_mkdir(), but if we add any file
3912creation functions to libext2fs, we should also make sure they respect
3913the umask setting.
3914
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05003915The build-rpm script was fixed to be a bit more safe.
3916
3917The tests' Makefile now has a way of automating test case creation
3918for e2fsck, using "make testnew".
3919
3920Created a new function, ext2fs_dir_iterate2 which passes more
3921information to the callback function (identical to the one used by
3922ext2fs_dblist_dir_iterate). The directory iterator functions take a
3923new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
3924directory entries. If the directory entry is deleted, the callback
3925function will be called with the entry paraemter set to
3926DIRENT_DELETED_FILE.
3927
3928Added new functions, ext2fs_inode_alloc_stats and
3929ext2fs_block_alloc_stats, which takes updates block/inode allocation
3930statistics in the bitmaps, block group descriptors, and superblock
3931when inodes or blocks are allocated or deallocated.
3932

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04003934E2fsprogs 1.25 (September 20, 2001)
3935===================================
3936
3937This is primarily a bug-fix release; no new features were added, but
3938there are a number of embarassing bug fixes and cleanups applied.
3939
3940Fix a bug mke2fs which causes stack garbage to be written to disk when
3941zapping disk sectors. (This bug could cause mke2fs to core dump for
3942some kernels, I suspect with security enhancement patches.)
3943
3944Remove unneeded #include of <linux/config.h> which was breaking
3945building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
3946
3947Updated tune2fs man page to reflect the fact that adding or removing a
3948journal doesn't require running e2fsck.
3949
3950Remove use of AC_REQUIRE from autoconf which had been used to prevent
3951AC_CANONICAL_HOST from being called twice; unfortunately this causes
3952recent autoconf to bomb out since they don't allow AC_REQUIRE to be
3953used outside of autoconf macros. Fortunately, it doesn't seem to be
3954necessary any more, anyway.
3955
3956E2fsck will now not fall back to an alternate superblock if the user
3957specifies the superblock location explicitly on the command-line.
3958This allows easier recovery from a situation where the primary
3959superblock and block groups are slightly corrupted, but the backup
3960superblocks are completely broken.
3961
3962Fix problem which caused compile_et and mk_cmds to blow up if
3963e2fsprogs was in a directory with a pathname that contained spaces.
3964
3965We are now more paranoid about checking the entry in /etc/mtab to make
3966sure the filesystem is really mounted, since some broken distributions
3967(read: Slackware) don't initialize /etc/mtab before checking non-root
3968filesystems. (Slackware also doesn't check the root filesystem
3969separately, and reboot if the root filesystem had changes applied to
3970it, which is dangerous and broken, but there's nothing I can do about
3971that.)
3972
3973Make UUID library C++ friendly by adding appropriate extern "C"
3974declarations and using const in the function declarations.
3975
3976Fix up the com_err texinfo file so that it can product a valid info
3977file (previously, it could only be used to generate paper
3978documentation using texinfo.tex).
3979
3980
Theodore Ts'ofb707752001-09-04 15:00:37 -04003981E2fsprogs 1.24a (September 2, 2001)
3982===================================
3983
3984Fix brown-paper bug in mke2fs which caused it to segfault when
3985printing the version string.
3986
3987
Theodore Ts'o109624a2001-08-31 00:59:55 -04003988E2fsprogs 1.24 (August 30, 2001)
3989================================
3990
3991Revert the BLKGETSIZE64 support, since for some distributions, this
3992ioctl has been used by an unofficial kernel patch to update the last
3993sector on the disk, and this was causing disk corruption problems as a
3994result.
3995
3996Mke2fs is now more careful about zapping swap space signatures and
3997other filesystem/raid superblock magic values so that programs like
3998mount who try to use hueristics to determine the filesystem type of a
3999partition are less likely to be confused.
4000
4001E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4002regular file (since Andreas Dilger's on-line resizing tools will set
4003its mode bits).
4004
4005Fixed some minor texinfo, man pages nits for spelling errors,
4006texinfo warnings, etc. (Addresses Debian bug #110621.)
4007
4008E2fsprogs program no longer print the filesystem version number
4009(i.e. 0.5b), since it only confuses people and doesn't serve any real
4010purpose.
4011
4012E2fsck will once again compile under libc5, since it will supply its
4013own version of strnlen if necesssary.
4014
4015mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4016when specifying the external journal device. tune2fs will also search
4017devices looking for the externla journal debice when removing.
4018
4019E2fsprogs 1.23 (August 15, 2001)
4020================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04004021
4022Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04004023correctly handle a filesystem with EA's and check the EA blocks for
4024corruptions.
4025
Theodore Ts'od494bba2001-08-09 06:14:42 -04004026E2fsck's symlink sanity checking has been cleaned up. It now checks
4027the i_size value of fast symlinks, and checks for immutable flags
4028being set of symlinks, etc.
4029
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004030E2fsck now offers to clear inodes which are special files that have a
4031non-zero i_blocks or i_size field. (The i_size field check was in the
4032previous version of the code, but due to a bug it didn't offer to
4033clear the inode unless i_size and i_size_high were both non-zero.)
4034
Theodore Ts'od494bba2001-08-09 06:14:42 -04004035E2image can now create "raw" image files, which only contain the
4036filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4037debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04004038
4039Add support for the 64-bit block device patches.
4040
4041Fixed bugs in creating external journals with a 1k blocksize.
4042
Theodore Ts'od494bba2001-08-09 06:14:42 -04004043Add initial support for external journals (so long as the external
4044journal only supports a single filesystem) in e2fsck.
4045
4046Remove requirement for needing to run fsck on a filesystem after
4047removing a journal (either internal or external).
4048
Theodore Ts'obf16d102001-07-27 22:20:06 -04004049The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04004050
4051Speed up the check of an ext3 filesystems by avoiding a needless flush
4052of all of the superblock and block group descriptors.
4053
Theodore Ts'od494bba2001-08-09 06:14:42 -04004054Speed up creating an internal journal using tune2fs in the case where
4055the filesystem has a lot blocks already allocated.
4056
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004057Tune2fs has been fixed to make sure that only error messages go to
4058stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4059
Theodore Ts'od494bba2001-08-09 06:14:42 -04004060Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004061now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04004062
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04004063Add support in fsck for the filesystem type "auto".
4064
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004065Fsck -A will not try to interpret device names for filesystems which
4066have a pass number is 0. (Addresses Debian bug #106696).
4067
4068Fsck prints a warning message if now valid filesystems are passed to
4069it. (Addresses Debian Bug #107458.)
4070
Theodore Ts'o9249d982001-07-20 18:14:10 -04004071E2fsck now gives an explicit warning if there filesystem still has
4072errors at the end of the run. (Addresses Debian bug #104502)
4073
Theodore Ts'od494bba2001-08-09 06:14:42 -04004074E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004075reflects an error. E2fsck will also not run the orphan list if the
4076filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04004077
4078E2fsck now prints the number of large files when given the -v option.
4079
4080Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04004081
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04004082Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04004083
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04004084
Theodore Ts'o19d6b542001-06-23 00:13:09 -04004085E2fsprogs 1.22 (June 22, 2001)
4086==============================
4087
4088Fixed a bug in e2fsck's handling of orphan inodes which are special
4089files (i.e., block/character device files, named FIFO's, etc.).
4090
4091Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4092tune2fs to fail at adding a journal to a mounted filesystem.
4093
4094Fixed a few big-endian bugs in e2fsprogs
4095 * The directory block functions were accidentally reporting
4096 some directories as corrupted when they weren't.
4097 * If e2fsprogs is compiled --disable-swapfs, the C language
4098 equivalents weren't being included for big-endian platforms.
4099 (Fixes Debian bug #101686).
4100
4101Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4102
4103Programmer's notes:
4104-------------------
4105
4106Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4107ioctls, and allow them to be defined for non-i386 platforms.
4108
4109The uuid.h header file is now protected against multiple inclusions.
4110
4111E2fsprogs is now being developed using BitKeeper. Changed the test
4112scripts to deal with BK's stripping CR characgters from text files,
4113and changed the top-level Makefile.in to avoid including BitKeeper
4114files when generating the source tarball.
4115
4116
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004117E2fsprogs 1.21 (June 15, 2001)
4118==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00004119
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004120Added new configure flags which allow a subset e2fsprogs to be built;
4121this is most useful for boot floopies, since the resulting shared
4122libraries and programs are slimmed down by removing features that
4123aren't necessary for a boot floppy. The new flags that were added
4124are: --disable-swapfs, which removes support for byte swapping old
4125legacy PPC/68k filesystems, --disable-debugfs, which removes support
4126for debugfs from the libext2fs library, --disable-imager, which
4127removes support for the e2image program, and --disable-resizer, which
4128removes support for resize2fs.
4129
4130E2fsck now prints the number of mounts or days elapsed since the last
4131check when e2fsck is forced to check an otherwise clean filesystem.
4132
4133Tune2fs now prints an informative message about how often a filesystem
4134will be checked when adding a journal to the filesystem, to remind the
4135user that he/she may want to adjust those parameters using tune2fs
4136-c/-i.
4137
4138Worked around hurd brain-damage which causes e2fsck to sometimes
4139believe a filesystem is the root filesystem based on device numbers
4140(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4141violation).
4142
4143Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4144erroneous error with the -F option was specified.
4145
4146Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004147ext3 0.7a.
4148
Theodore Ts'o767de092001-06-02 01:20:18 +00004149Fixed two bugs in e2fsck's handling of dup block handling, dealing
4150with relatively uncommon edge cases: a directory with an indirect
4151block which is claimed by another file, and when the last inode in the
4152filesystem has blocks claimed by another file.
4153
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00004154E2fsck now checks to see if the i_size field of a fast symlink is too
4155big, and offers to clear the symlink if so.
4156
4157E2fsck now checks to see if i_size_high of special files is non-zero,
4158and offers to clear i_size_high.
4159
Theodore Ts'o767de092001-06-02 01:20:18 +00004160Fix e2fsck's handling of incompatible journal flags so that the user
4161has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00004162entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00004163
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004164Fixed a bug in fsck which could cause it to core dump if a mix of
4165standard and non-standard device names are used in /etc/fstab.
4166(Debian bug #100559)
4167
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004168Fixed a bug in debugfs which caused read errors when copying a file to
4169not be noticed.
4170
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004171The debugfs set_super_value command can now modify the s_lastcheck field.
4172
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004173Fixed a bug in lsattr and chattr which was accidentally introduced in
41741.20 to support > 2GB files; both lsattr and chattr wasn't reading
4175directories correctly because the change modified the layout of struct
4176dirent to be incompatible with the libe2p shared library.
4177
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004178Cleaned up the mke2fs manual page and included a discussion about why
4179it's good to periodically check the filesystem even when journaling is
4180enabled.
4181
Theodore Ts'o767de092001-06-02 01:20:18 +00004182Programmer's notes:
4183-------------------
4184
4185Fix general gcc -Wall complaints.
4186
4187The types needed by the ext2 header files are now provided by
4188lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4189
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004190Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004191in ext2_types.h. Also, if linux/types.h has already been defined,
4192don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004193
Theodore Ts'o767de092001-06-02 01:20:18 +00004194Fixed make depend script so that it automatically corrects the
4195pathname cleanups performed by make -M, so I don't have to fix them up
4196by hand.
4197
4198Fixed the d_loaddump test case to be more robust, and not depend on
4199bash'isms.
4200
4201Removed debugfs's dependence on pread(), which was accidentally
4202intrudced in e2fsprogs 1.20
4203
Theodore Ts'oc05b5522001-06-08 12:03:36 +00004204Fixed a performance bug in the libext2fs's icount routine; the size
4205estimate of the icount array was incorrectly being calculated.
4206
Theodore Ts'ob90b8262001-06-15 22:54:34 +00004207Removed use of the badblocks compatibility functions in the e2fsprogs
4208programs.
4209
4210Added paranoia code which protects against strange cases where /etc
4211isn't on the root filesystem, or if /etc/mtab doesn't exist.
4212
4213The header file ext2_types.h is now installed.
4214
4215Autoconf is used to determine when we are on big-endian machines,
4216instead of doing run-time tests, to save a few bytes of code.
4217
4218The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4219functions are no longer inline functions, which saves space and
4220doesn't really cost any real performance.
4221
4222The ext2fs library no longer depends on the e2p library. (What need
4223there was of it --- namely, fsetflags, was coded in-line).
4224
4225Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4226when the user is stupid and tries compiling the package using "make
4227install" as root.
4228
4229Miscellaneous code cleanups:
4230 * Added missing files from Makefile.in's SRCS file, so that
4231 their dependencies would be properly calculated.
4232 * Removed redundant code
4233 * Fixed comments in code
4234 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00004237E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004238=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00004239
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004240Add support for replaying the ext3 journal purely in user mode,
4241including handling the orphaned inode list. Used code contributed by
4242Andreas Dilger, with bug fixes and the orphaned inode handling done
4243by Theodore Ts'o.
4244
4245The mke2fs and tune2fs programs can create or modify a filesystem to
4246include an ext3 journal. Tune2fs also can be used to remove an ext3
4247journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004248
4249E2fsck will now check for the existence of a linked list of orphan
4250inodes in the superblock, and clear those inodes before starting the
4251rest of the filesystem check (but after the journal playback).
4252
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004253E2fsck now validates the file descriptor passed to the -C option,
4254which saves against the completion bar getting written to an
4255unexpected location, such as the disk being checked. (Debian
4256bug/wishlist #55220)
4257
4258E2fsck will now bump the filesystem revision number from zero to one
4259if any of the compatibility bits are set.
4260
4261Fixed a bug where a badly corrupted directory on a big endian system
4262could cause e2fsck to die with a bus error. The
4263ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4264the ext2 library now does alignment sanity checks on the rec_len field
4265of the directory entry before using it.
4266
4267The ext2 library has been enhanced to make tune2fs safe to run on
4268mounted filesystems. (Users could usually get away with using tune2fs
4269on mounted filesystems before, but with the advent of ext3 and
4270journaling, it became important to make tune2fs was *really* safe for
4271use even when the filesystem being modified is mounted.) E2label is
4272now implemented by tune2fs using an argv[0] dispatch, so that e2label
4273is also now safe for use on mounted filesystems.
4274
4275Added a new program, e2image, which creates a backup of critical ext2
4276filesystem data structures. The generated image file can be examined
4277using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4278the image file to help recover very badly damaged filesystems.
4279
4280Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4281no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4282large file when deciding whether or not the filesystem has large files.
4283
4284Fixed lsattr and chattr so that they work correctly on large files.
4285(Fixes Debian bug #72690.)
4286
4287Removed limitation in get_device_size() which imposed a one terrabyte
4288filesystem limitation. (Most 2.2 kernels still have a signed int
4289problem which cause 1 TB block device limitation. Fortunately, the
4290kernel patches to fix this are much easier than fixing the 2TB
4291limitation in the kernel. :-)
4292
4293A max_mount_count of zero is now treated as if no mount count were
4294set. (Previously, no mount count was indicated by using -1, and a
4295mount count of zero caused e2fsck to always be run.)
4296
Theodore Ts'o77648562001-05-14 13:04:44 +00004297Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004298
4299Mke2fs now adds some randomness in s_max_mount_count so that multiple
4300filesystems won't be all checked at the same time under normal
4301operations.
4302
Theodore Ts'o5570a652000-08-21 01:23:39 +00004303Fixed bug in the progress bar printing code which could cause e2fsck
4304to core dump on an illegal filesystem.
4305
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004306Fixed bug in fsck which could allow more than one instance of e2fsck
4307to be printing a progress bar. (Debian bug #65267)
4308
Theodore Ts'o5570a652000-08-21 01:23:39 +00004309Fsck using a UUID or a LABEL specifier will work even if devfs is
4310compiled into the kernel and not mounted. If the pathnames in
4311/proc/partitions are incorrect, fsck will search /dev for the correct
4312device (using the new ext2fs_find_block_device library function).
4313Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004314found when they are in use. Support has also been added to support
4315additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4316
4317Fixed a bug in fsck which caused it not deal properly with 16
4318byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004319
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00004320Fsck's -t option has been made a lot more flexible. The semantics for
4321what happens if a comma-separated list to fsck has been regularized,
4322and it is now possible to filter what filesystems will get checked
4323based what is in the filesystem's fstab entry's option field. (Debian
4324bug #89483.)
4325
Theodore Ts'o5570a652000-08-21 01:23:39 +00004326The dumpe2fs program can now print out the group description
4327information in hex, and also prints the location of the superblock and
4328block group descriptor for those block groups that have them.
4329
4330Mke2fs now clears the ext2 superblock before it starts creating a
4331filesystem, so that the superblock magic number is only written if the
4332filesystem creation process successfully completes.
4333
4334The debugfs program's stat command now pretty-prints the blocks used
4335by an inode so that it's more compact and informative.
4336
4337The debugfs stats command now uses the same libe2p code (which is used
4338by dumpe2fs) to print the superblock header information. This is more
4339complete, and it avoids a bit of code duplication.
4340
4341Added a new debugfs command, set_super_value (ssv) which allows the
4342user to set arbitrary superblock fields.
4343
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004344Debugfs was extended to support inode numbers in hex (by prefixing
4345them with 0x), and so that modify_inode can set the inode generation
4346number. Also, there is now a new function command called logdump
4347which will dump an ext3 journal.
4348
4349Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4350debugfs.
4351
4352Debugfs's dump command now stops immediately upon reporting a disk
4353read error. (Fixed a bug in ext2fs_file_read library routine which
4354caused debugfs not to stop.) (Debian bug #79163)
4355
4356On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4357checked before /etc/mtab is used, since /proc/mounts is more likely to
4358be accurate.
4359
4360Added portability fixes for Solaris and Linux/ia64.
4361
4362Various manual pages were clarified and cleaned up. (Fixed debian
4363bugs #63442, #67446, and #87216)
4364
Theodore Ts'o5570a652000-08-21 01:23:39 +00004365
4366Programmer's notes:
4367-------------------
4368
4369The e2fsck message printer now supports %Iu and %Ig, which will print
4370out the inode's user and group owners, respectively.
4371
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004372E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4373that no longer dependent on the system having the correct version of
4374the kernel header files.
4375
Theodore Ts'o5570a652000-08-21 01:23:39 +00004376Added a new function to libext2, ext2fs_find_block_device(), which
4377searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4378device given its device number.
4379
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004380Added a new function to libext2, ext2fs_sync_device, which centralizes
4381all of the places which might try to use the BLKFLSBUF or FDFLUSH
4382ioctls (and usually failing to define them since the system header
4383files don't usually do this for us, and we're trying to avoid usage of
4384kernel include files now).
4385
Theodore Ts'o5570a652000-08-21 01:23:39 +00004386Added new utility programs in tests/progs: random_exercise and
4387hold_inode. They aren't built by default; they're useful for
4388exercising ext3 filesystem code.
4389
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004390Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4391the filesystem close functions to only update the superblock, and to
4392not touch the block group descriptors. Needed by tune2fs when
4393modifying a mounted filesystem.
4394
4395Got rid of struct ext2fs_sb and replaced it with the standard struct
4396ext2_super_block from include/linux/ext2_fs.h. Note: this may break
4397source (but not binary) compatibility of some users of the ext2
4398library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00004399replace of struct ext2fs_sb with struct ext2_super_block, and include
4400the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004401
4402The ino_t type has been renamed ext2_ino_t to protect applications
4403that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4404inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
4405unexpected ABI change.
4406
4407The Makefiles have been reworked so that "make check" can be run from
4408the top-level Makefile.
4409
4410Fix general gcc -Wall complaints and removed dead code.
4411
4412Remove use of NOARGS, because we assume everyone does ANSI C these
4413days.
4414
4415Added build-rpm script from sct.
4416
4417New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
4418to support e2image.
4419
4420New function ext2fs_flush_icache which must be called if the
4421application program modifies the inode table blocks without going
4422through ext2fs_write_inode() interface.
4423
4424New ext2fs_check_mount_point() function, which will return the mount
4425point of a device if mounted.
4426
4427The io_channel abstraction now has an optional interface,
4428io_channel_write_range, which allows specific byte ranges to be
4429written.
4430
4431The unix_io IO channel now supports write-through caching, so that
4432journal creation is more efficient.
4433
4434Added x86 assembly language routines to support byte swapping, to
4435reduce executable size.
4436
4437Fixed bug in the utility program subst so that it's possible to
4438replace a substitution variable with a zero-length string.
4439
4440Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4441slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00004442
Theodore Ts'ob777e262000-07-27 01:39:23 +00004443E2fsprogs 1.19 (July 13, 2000)
4444==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00004445
4446Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00004447be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00004448
4449Add experimental support needed for the ext2 compression patches.
4450This requires compiling e2fsprogs with the --enable-compression flag
4451to the configure script.
4452
4453Added ext3 journalling support. E2fsck will run the journal (if
4454necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
4455installed as a symlink to e2fsck. Fsck has been taught about ext3,
4456and treats it the same as ext2 in terms of the progress bar logic.
4457Dumpe2fs will display the superblock journaling information if the
4458filesystem has a journal. The ext2 library will now permit opening an
4459ext3 filesystem with the recovery flag set. This is necessary for
4460on-line dump's to work correctly, but there may be issues with this
4461working well since ext3 is much less agressive about syncing blocks to
4462the filesystem, since they're safe on the journal.
4463
4464Tune2fs and e2fsck have been changed to allow the mount_count check to
4465be disabled by setting max_mount_count to -1. (This was already
4466supported by the kernel.)
4467
4468Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4469are used for ext3 as well.
4470
4471Added internationalization support for e2fsprogs; must be enabled
4472by passing --enable-nls to configure.
4473
4474Always use the provided ext2fs header files to insulate ourselves from
4475kernel version changes. Which include files are used by e2fsprogs
4476have also been cleaned up to improve portability.
4477
4478Limit the number of times that e2fsck updates the progress bar so that
4479people who are booting using a 9600 baud console don't get swampped by
4480too many updates.
4481
4482Improved the loop detection algorithm in e2sck's pass #3 so that it is
4483much, much faster for large filesystems with a large number of
4484directories.
4485
4486The memory footprint for e2fsck is now slightly smaller than before.
4487
4488E2fsck now checks if special devices have a non-zero size, and offers
4489to clear the size field if it finds such an inode.
4490
4491E2fsck now checks if special devices have the append-only flag set,
4492and offers to clear the inode.
4493
4494E2fsck now properly handles some "should never fail" cases during a
4495bitmap copy in pass5.
4496
4497E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4498
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004499E2fsck now calculates the correct location of the backup superblock in
4500the case of filesystem blocksizes > 1k.
4501
4502Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4503which normally didn't cause problems under most filesystem parameters,
4504but could cause a valid superblock to be rejected in extreme cases.
4505Other checks for validating superblock values were made more
4506stringent.
4507
Theodore Ts'oab146762000-07-07 04:37:35 +00004508Added non-destructive write testing to the badblocks program, courtesy
4509of David Beattie. The badblocks also now has an option to input the
4510current set of bad blocks, so that known bad blocks are skipped to
4511speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00004512feature which causes badblocks to run until it has completed some
4513number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00004514
4515Badblocks now checks to see if the device is mounted and refuses to do
4516the tests involving writing to the device if it is mounted. Also,
4517badblocks now allows the number of blocks to be checked to be
4518defaulted to the size of the partition.
4519
4520Fixed a bug in fsck which didn't allow non-root users to be able to
4521check filesystems if there were any LABEL= or UUID= entries in
4522/etc/fstab.
4523
4524The Hurd doesn't support the filetype filesystem feature. The mke2fs
4525program now makes sure that for the Hurd, the filestype feature is
4526turned off. E2fsck will check to see if the filetype feature is
4527turned on for Hurd filesystems, and offer to turn off the feature.
4528
4529Mke2fs now has a safety check to make sure the number of blocks do not
4530exceed 32 bits even on a 64 bit platform.
4531
4532Really fixed a bug in fsck to allow "fsck -As" to run interactive
4533fsck's. (For those people who like to do interactive fsck's in the
4534/etc/rc scripts!?!)
4535
4536Debugfs has a few new features: the rdump command, which will do a
4537recursive dump of a directory and all of its contents, and the lcd
4538command which does a local chdir (much like the ftp command of the
4539same name). In addition, the debugfs program and the open_filesystem
4540command now takes three new options: -b and -s, which allows the
4541blocksize and superblock location to be specified, and the -c option
4542which is used in catastrophic situations where the block group
4543descriptors are corrupt. If the -c option is specified, debugfs will
4544skip trying to read in the block and inode bitmaps.
4545
4546Debufs's lsdel command was fixed to handle bad blocks in the inode
4547table.
4548
4549A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
45504 digit years.
4551
4552General improvements in error messages
4553
4554 - Mke2fs prints a sane error message if the partition size is zero
4555 (usually because the partition table wasn't reread by the
4556 kernel due to the partition being busy), instead of "invalid
4557 argument passed to ext2 library while initializing superblock".
4558
4559 - Fsck now prints more self-explanatory message if an invalid UUID=
4560 or LABEL= specification is passed to it.
4561
4562UUID library changed to use the LGPL.
4563
4564Fixed a bug in the UUID library where very rapid calls to the
4565time-based UUID generator could cause duplicate UUID's to be returned.
4566This was not a problem for e2fsprogs, but it could be a problem for
4567other users of the library.
4568
4569Make the UUID library more robust in the face of missing or an
4570improper /dev/urandom or /dev/random files.
4571
4572Added some random portability fixes for Solaris.
4573
4574Some minor man page updates.
4575
4576Fixed a memory leak in the ss library.
4577
4578
4579Programmer's notes:
4580-------------------
4581
4582We now try to use lseek64 and open64 from the LFS if possible.
4583
4584The 3rd parameter in e2p's print_flags is now a flags word, instead of
4585a boolean option.
4586
4587The mark and unmark bitmap functions now return the previous state of
4588the bit that was being changed, which is useful for some speed
4589optimizations.
4590
4591The following functions have been added to enhance the badblocks list
4592handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
4593ext2fs_badblocks_equal.
4594
4595The ext2 header files now have the latest journalling fields to the
4596superblock.
4597
4598The ext2fs_mkdir function in libext2fs now properly backs out of error
4599conditions robustly.
4600
4601Cleaned up makefiles:
4602 - to cleanly compile with the -j flag.
4603 - so distclean removes all generated files.
4604 - so in case of an error while installing header files, the make aborts.
4605
4606Fix test_script so that it works correctly when compiling in the
4607source directory.
4608
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00004609The random UUID generation routine has been made slightly better in
4610the case where /dev/random doesn't exist. (Use of randomly-based UUID
4611is still not recommended if /dev/random doesn't exist, however; it's
4612better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00004613
4614Clean up the build process so it's more friendly in case of missing
4615directories.
4616
4617The ext2fs header file can now be #include'd into C++ programs.
4618
4619The e2p.h header file is now installed.
4620
4621Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
4622
4623

Theodore Ts'o24ded091999-11-10 15:56:16 +00004625E2fsprogs 1.18 (November 10, 1999)
4626==================================
4627
4628Fix a core dumping bug in e2fsck if an imagic inode is present or
4629(more rarely) if the filesystem is badly corrupted enough that e2fsck
4630has to restart pass 1 processing. E2fsck now closes the filesystem
4631before freeing a large number of its data structures, so in the case
4632of future memory faults, at least the fixed filesystem will be fully
4633written out.
4634
4635If a filesystem doesn't support imagic inodes, and e2fsck discovers an
4636imagic inode, it will offer to clear the imagic flag.
4637
4638E2fsck will now offer to clear the immutable flag on special files
4639(device/socket/fifos) when running it in non-preen mode.
4640
4641E2fsck will now set the filetype when creating /lost+found, and when
4642connected orphaned inodes to /lost+found.
4643
4644Debugfs's ncheck and icheck commands now handles the case where there
4645are bad blocks in the inode table without bombing out.
4646
4647The badblocks list processing code has been made more efficiently for
4648appending a large number of (ordered) badblocks to the badblocks list.
4649
4650Some minor man page updates.
4651
4652Fsck now allows interactive e2fsck's when using fsck -As (not a common
4653mode, but some people like to do this in boot scripts for silly reasons).
4654
4655Programmer's notes:
4656-------------------
4657
4658The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
4659with the problem code convention.
4660
4661The badblocks list regression test program has been updated to work
4662with previously made API name changes.
4663
4664The ext2fs_free() command now uses the new badblocks API to avoid
4665using the compatibility layer.
4666
4667Added new regression test cases; the run_e2fsck test script now
4668supports the ability for a test case to run a prepratory command
4669before running e2fsck.
4670
Theodore Ts'o28e11941999-10-26 18:17:20 +00004671E2fsprogs 1.17 (October 26, 1999)
4672=================================
4673
4674Fixed nasty typo in fsck which caused parallelized fsck's to go into an
4675infinite loop.
4676
4677Fixed a bug in fsck where it used strncmp to compare a binary UUID,
4678thus potentially causing problems if a binary UUID contained a NULL
4679character.
4680
4681E2fsck now uses stricter checks for directory entries in pass 2:
4682zero-length filenames are not allowed; neither are 8 byte long
4683directory entries.
4684
4685The debugfs "dirty" command now clears the filesystem valid bit.
4686(Previously this just set the dirty-as-in-needs-writing-out-to-disk
4687bit in the in-core superblock image. The new functionality is more
4688what the user expects, and is more useful.)
4689
4690Added a debugging hook to test parallel fsck; if the environment
4691variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
4692will be checked in parallel when they normally would not be.
4693
4694Programmer's notes:
4695-------------------
4696
4697Fixed some #ifdef's for compilation under the Hurd OS.
4698
4699Fixed minor W2K compatibility problems.
4700
4701Fixed some miscellaneous GCC warnings.
4702
4703
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00004704E2fsprogs 1.16 (October 22, 1999)
4705=================================
4706
4707Fixed a race condition bug in fsck; when printing a progress bar, if
4708checking multiple filesystems in parallel, it was possible for fsck to
4709send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
4710handler, which would cause it to terminate with a signal 10.
4711
4712E2fsck now properly handles filesystems that have the
4713INCOMPAT_FILETYPE feature turned on. It can be used to convert a
4714filesystem into using or not using FILETYPE feature.
4715
4716E2fsck now properly handles filesystems that have the IMAGIC feature
4717turned on (this is used on Linux AFS servers).
4718
4719The mke2fs program now creates filesystems that have the filetype and
4720sparse_superblock features enabled by default, unless it is run on a
4721pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
4722so there is now a new flag -O which allows the user to specify with
4723which features she would like to create the filesystem; "mke2fs -O
4724none" will create a filesystsem compatible with 2.0 kernels.
4725
4726The tune2fs program now has a -O option which allows the user to set
4727and reset "safe" filesystem features. Currently, the only ones which
4728allows to be modified are the filetype and sparse_superblock features.
4729Note setting or clearing either feature will require running e2fsck on
4730the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
4731requires that there is enough free space on the filesystem for the
4732extra superblocks which will be created by e2fsck.)
4733
4734Debugfs can now set and print filesystem features in the superblock
4735using the "features" command. Dumpe2fs will print out the complete
4736set of features when listing the superblock.
4737
4738Dumpe2fs has new options -f (force) and -h (header-only).
4739
4740Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
4741message to come up. This could happen when decrementing or
4742incrementing a link count could result in an overflow.
4743
4744Fixed a bug in e2fsck where the block count on the lost+found
4745directory would not be properly incremented when the directory was
4746expanded to the point where an indirect block needed to be allocated.
4747
4748E2fsck now makes some additional sanity checks on the superblock to
4749avoid crashing or giving a memory allocation error if some of the
4750values in the superblock are unresonable (but the superblock otherwise
4751looks valid).
4752
4753Fixed a bug in e2fsck where a very badly corrupted filesystem might
4754require two passes to completely fix the filesystem. This happened if
4755an inode claimed blocks that was part of the filesystem metadata
4756(typically, when garbage was written into an inode table or indirect
4757block, since this kind of filesystem corruption normally doesn't
4758happen otherwise).
4759
4760On the Alpha, glibc declares st_flags although it isn't actually used;
4761the configure script was improved to detect this case so that
4762e2fsprogs can avoid using the non-functional stat field.
4763
4764The manual pages were updated to use a more consistent formatting
4765style consistent with standard Unix man pages. Mke2fs's man page
4766added documentation for a few previously undocumented options.
4767
4768Fixed minor display bugs in tune2fs and mke2fs.
4769
4770Programmer's notes:
4771-------------------
4772
4773Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
4774
4775Added features to parse and print feature strings into the e2p library.
4776(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
4777
4778ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
4779whose directory entries contain proper filetype information if the
4780filesystem supports it.
4781
4782ext2fs_link() now uses the low 3 bits of its flags parameter to pass
4783the directory entry filetype information. This is used to set the
4784directory entry filetype information if the filesystem supports it.
4785
4786Fixed a bug in ext2fs_expand_dir() where the block count in a
4787directory's inode would not be properly incremented when the directory
4788was expanded to the point where an indirect block needed to be
4789allocated.
4790
4791
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004792E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004793==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004794
4795Add configuration checks so that e2fsprogs will compile cleanly on
4796Linux 2.3 kernels that have renamed i_version to i_generation.
4797
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004798E2fsck now prints a progress/completion bar (and not just a simple
4799spinner) if the -C0 option is requested or if it receives a SIGUSR1
4800signal. Fsck will automatically manage the (potentially muliple)
4801e2fsck processes to print completion bars if it is given a -C option,
4802with the right thing happening if multiple filesystems are being
4803checked in parallel.
4804
4805Mke2fs now has better automatic hueristics to determine the filesystem
4806parameters to be used for a particular filesystem. Added a new option
4807-T which allows the user to specify how the filesystem is to be used,
4808which helps mke2fs do a better job selecting the filesystem parameters.
4809
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004810Mke2fs now creates revision 1 filesystems by default, and with the
4811sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00004812not understood by Linux 2.0 kernels, so they will only allow read-only
4813mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004814
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004815Fix bug where if /dev/null couldn't be opened (should never happen),
4816e2fsck would hang in a tight loop.
4817
4818Make e2fsck handle the case where /lost+found isn't a directory.
4819
4820E2fsck now uses mallinfo if it exists to get accurate statistics about
4821its memory usage.
4822
4823Fix bug in e2fsck where it wouldn't check to see if a disconnected
4824inode had any problems before connecting it to /lost+found.
4825
4826Add check to e2fsck so it makes sure that total number of inodes in
4827the filesystem is a sane number.
4828
4829Fix fencepost error when clearing an the end of the block bitmap which
4830caused the last block in the bitmap not to get cleared.
4831
4832Cleaned up a number of messages in e2fsck:
4833 * The message "Group's #'s copy of the group descriptor..."
4834 was fixed so that the correct number would be displayed.
4835 * Added missing space in the "disk write-protected" error messsage
4836 * Cleaned up the error message printed when a non-interactive
4837 e2fsck needs to abort a check because the filesystem
4838 appears to be mounted.
4839
4840Added a new command-line utility, uuidgen, which will create and print
4841a UUID.
4842
4843Make debugfs's icheck command more robust by checking to make sure an
4844inode has valid blocks before interarting over the inode's blocks.
4845
4846UUID generation now uses a random-based scheme whenever possible to
4847prevent potential privacy problems.
4848
4849Man pages for all of the UUID functions in the lirbary were added.
4850
4851Fixed bug in fsck so it won't coredump if a filesystem not in
4852/etc/fstab is given to it.
4853
4854Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
4855that most of the other mount utilities understands.
4856
4857Mke2fs will make a filesystem even if it appears mounted if the force
4858option is given.
4859
4860Dumpe2fs has new command-line options which allow a filesystem expert
4861to specify the superblock and blocksize when opening a filesystem.
4862This is mainly useful when examining the remains of a toasted
4863filesystem.
4864
4865The badblocks program has been updated to display correctly on disks
4866with large block numbers.
4867
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00004868The badblocks program no longer gives spurious errors when errors
4869occur on non-block boundaries, which is common if the blocksize is
4870larger than 1k.
4871
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004872Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
4873MKE2FS_SYNC environment variable is set. This is to work around a VM
4874bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00004875to trigger it even using a 2.2 kernel, but hopefully it will not be
4876needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00004877
4878Fixed miscellaneous documentation and man pages.
4879
4880Programmer's notes:
4881-------------------
4882
4883Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
4884in e2fsck's pass1.c really should have been static.
4885
4886The return value of the uuid_compare() function was changed to make it
4887match with the convetions used by strcmp, memcmp, and Paul Leach's
4888UUID sample document.
4889
4890The "make depend" process has now been made more automated; it now
4891automatically word-wraps the dependencies, and only replaces source
4892Makefile.in if there has been a change in the dependencies. Also, a
4893top-level "make depend" now recurses through all the subdirectories
4894automatically.
4895
4896The Makefile in .../util has been changed so that subst is built using
4897the native C compiler during a cross-compilation, since the subst
4898program is only used during the build process. Also add an explicit
4899rule to build util/subst by cd'ing to the correct directory and
4900running Makefile.
4901
4902The man directories are defined in terms mandir, so that the configure
4903script can override the location of the manual pages.
4904
4905The config files have been updated to recognize new machine types for
4906both the i386 and alpha families.
4907
4908Fsck has been modified so that it will accurately create an
4909fsck_instance even when the noexecute flag is set. This allows for
4910accurate debugging of the fsck pass structure. Also, when the verbose
4911flag is given twice, fsck will print debugging information about when
4912fsck is waiting for jobs to finish.
4913
4914
Theodore Ts'o14790ed1999-01-12 23:32:52 +00004915E2fsprogs 1.14 (January 9, 1999)
4916================================
4917
4918Fix the fstab parsing code so that it can handle blank lines and
4919comment characters. Also, missing pass numbers need to be treated as
4920zero.
4921
4922Fixed a bug in e2fsck where under some circumstances (when e2fsck
4923needs to restart processing after fixing an egregious inconsistency)
4924it would try to access already freed memory.
4925
4926E2fsck now prints non-printable characters in directory entries and
4927pathnames using '^' and 'M-' notation.
4928
4929Fixed chattr so that it will ignore symbolic links when doing
4930recursive descent traversals. For both chattr and lsattr, no longer
4931print the version string unless the -V option is given.
4932
4933Allow the system administrator to directly specify the number of
4934inodes desired in the filesystem, for some special cases where this is
4935necessary.
4936
4937Fix portability problems so that e2fsprogs can be compiled under Linux
49381.2 systems and Solaris systems.
4939
4940Update the config.guess file with a more recent version that will
4941identify newer Linux platforms.
4942
4943Programmer's notes
4944------------------
4945
4946Ext2fs_read_inode and ext2fs_write_inode will now return an error if
4947an inode number of zero is passed to them.
4948
Theodore Ts'o556ad131998-12-19 08:10:58 +00004949E2fsprogs 1.13 (December 15, 1998)
4950==================================
4951
4952Fixed a bug in debugfs where an error messages weren't getting printed
4953when the ext2 library routines to read inodes returned errors in the
4954stat, cmri and rm commands.
4955
4956Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
4957provided, it won't create an inode table smaller than the minimum
4958number of inodes required for a proper ext2 filesystem.
4959
4960Fsck now parses the /etc/fstab file directly (instead of using
4961getmntent()), so that it can distinguish between a missing pass number
4962field and pass number field of zero. This caused problems for
4963diskless workstations where all of the filesystems in /etc/fstab have
4964an explicit pass number of zero, and fsck could not distinguish this
4965from a /etc/fstab file with missing pass numbers.
4966
4967E2fsck will create a /lost+found directory if there isn't one in the
4968filesystem, since it's safer to create the lost+found directory before
4969it's needed.
4970
4971Fixed e2fsck so that it would detect bogus immutable inodes which
4972happen to be sockets and FIFO files, and offer to clear them.
4973
4974If a filesystem has multiple reasons why it needs to be checked, and
4975one of the reasons is that it is uncleanly mounted, e2fsck will print
4976that as the reason why the filesystem is being checked.
4977
4978Cleaned up the output routines of mke2fs so that it doesn't overflow
4979an 80 column display when formating really big filesystems.
4980
4981Added a sanity check to e2fsck to make sure that file descriptors 0,
49821, 2 are open before opening the hard disk. This avoids a problem
4983where a broken program might exec e2fsck with those file descriptors
4984closed, which would cause disastrous results if the kernel returns a
4985file descriptor for the block device which is also used by FILE *
4986stdout.
4987
4988Fixed up the e2fsck progress reporting functions so that the values
4989reliably reach 100% at the completion of all of the e2fsck passes.
4990
4991Fixed minor documentation bugs in man pages and usage messages.
4992
4993Programmer's notes:
4994-------------------
4995
4996Fixed a number of lint warnings in the ext2fs library and potential
4997portability problems from other OS's header files that might define
4998CPP macros for names like "max" and "min".
4999
5000ext2fs_badblocks_list_add() has been made more efficient when it needs
5001to grow the bad blocks list.
5002
5003Fixed a bug in e2fsck which caused it to dereference a freed pointer
5004just before exiting.
5005
5006Fixed the substition process for generating the mk_cmds and compile_et
5007scripts so that they will work outside of the build tree.
5008
5009Add sanity check to e2fsck so that if an internal routine
5010(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5011and causing a core dump. This should never happen, but...

Theodore Ts'oa5696711998-07-09 05:38:07 +00005013E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00005014==================================
5015
5016E2fsprogs now works with glibc (at least with the version shipped wtih
5017RedHat 5.0). The ext2fs_llseek() function should now work even with
5018i386 ELF shared libraries and if llseek() is not present. We also
5019explicitly do a configure test to see if (a) llseek is in libc, and
5020(b) if llseek is declared in the system header files. (See standard
5021complaints about libc developers don't understand the concept of
5022compatibility with previous versions of libc.)
5023
Theodore Ts'oc9833a61998-07-05 19:37:53 +00005024The ext2fs library now writes out the block group number in each of
5025the superblock copies. This makes it easier to automatically
5026determine the starting block group of the filesystem when the block
5027group information is trashed.
5028
5029Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00005030which means that e2fsprogs will ignore the high 8 bits of the
5031directory entry's name_len field, so that it can be used for other
5032purposes.
5033
5034Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5035E2fsprogs will now support filesystems with 64-bit sized files.
5036
5037Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5038
Theodore Ts'o21d53851998-02-21 03:14:50 +00005039Added new program "e2label", contributed by Andries Brouwer. E2label
5040provides an easy-to-use interface to modify the filesystem label.
5041
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00005042Fixed bug so that lsattr -v works instead of producing a core dump.
5043
Theodore Ts'o21d53851998-02-21 03:14:50 +00005044Fixed a minor bug in mke2fs so that all groups with bad superblock
5045backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00005046
5047Mke2fs will check the size of the device, and if the user specifies a
5048filesystem size larger than the apparent size of the device it will
5049print a warning message and ask if the user wants to proceed.
5050
Theodore Ts'oc9833a61998-07-05 19:37:53 +00005051E2fsck has a new option -C, which sends completion information to the
5052specified file descriptor. For the most part, this is intended for
5053programs to use, although -C 0 will print a spinning character to the
5054stdout device, which may be useful for users who want to see something
5055happening while e2fsck goes about its business.
5056
Theodore Ts'o21d53851998-02-21 03:14:50 +00005057Fixed a bug in e2fsck which could cause a core dump when it needs to
5058expand the /lost+found directory, and sometimes the bitmaps haven't
5059been merged in. Also fixed a related bug where ext2fs_write_dir_block
5060was used to write out a non-directory block. (Which would be bad on a
5061non-Intel platform with byte swapping going on.)
5062
5063Fixed bug in e2fsck where it would print a "programming error" message
5064instead of correctly identifying where a bad block was in used when
5065the bad block was in a non-primary superblock or block group
5066descriptor. Also fixed a related bug when sparse superblocks are in
5067use and there is a bad block where a superblock or block group
5068descriptor would have been in a group that doesn't include a
5069superblock.
5070
5071Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5072the block group descriptor table is corrupt, it was possible to try to
5073allocate a huge array, fail, and then abort e2fsck.
5074ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5075and subsitutes reasonable values if the descriptors are obviously bogus.
5076
5077If e2fsck finds a device file which has the immutable flag set and the
5078i_blocks beyond the normal device number are non-zero, e2fsck will
5079offer to remove it, since it's probably caused by garbage in the inode
5080table.
5081
5082When opening a filesystem, e2fsck specially checks for the EROFS error
5083code, and prints a specific error message to the user which is more
5084user friendly.
5085
5086If the filesystem revision is too high, change the e2fsck to print
5087that this is either because e2fsck is out of date, or because the
5088superblock is corrupt.
5089
5090E2fsck now checks for directories that have duplicate '.' and '..'
5091entries, and fixes this corruption.
5092
5093E2fsck no longer forces a sync of the filesystem (with attendant sleep
5094calls) at all times. The ext2fs_flush() function now performs a sync
5095only if it needed to write data blocks to disk.
5096
5097Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5098certain errors would not be properly reported.
5099
5100Updated and expanded a few points in the man pages which users
5101complained wheren't explicit enough.
5102
5103Added special case byte-swapping code if compiling on the PowerPC, to
5104accomodate the strange big-endian variant of the ext2 filesystem that
5105was previously used on the PowerPC port.
5106
5107
5108Programmer's notes:
5109-------------------
5110
5111Removed C++ keywords from the ext2fs libraries so that it could be
5112compiled with C++.
5113
5114E2fsck's internal organization has now been massively reorganized so
5115that pass*.c don't have any printf statements. Instead, all problems
5116are reported through the fix_problem() abstraction interface. E2fsck
5117has also been revamped so that it can be called as a library from a
5118application.
5119
5120Added new fileio primitives in libext2fs for reading and writing
5121files on an unmounted ext2 filesystem. This interface is now used by
5122debugfs.
5123
5124Added a new libext2fs function for mapping logical block numbers of
5125a file to a physical block number.
5126
5127Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5128a block, zeros it, and updates the filesystem accounting records
5129appropriately.
5130
5131Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5132sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5133
5134The libext2fs functions now use a set of memory allocation wrapper
5135functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5136instead of malloc, free, and resize. This makes it easier for us to
5137be ported to strange environments where malloc, et. al. aren't
5138necessarily available.
5139
5140Change the libext2fs fucntion to return ext2-specific error codes
5141(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5142and depending on the existence of system error codes (such as EEXIST
5143and ENOENT).
5144
5145Renamed io.h to ext2_io.h to avoid collision with other OS's header
5146files.
5147
5148Add protection against ext2_io.h and ext2fs.h being included multiple
5149times.
5150
5151The types used for memory lengths, etc. have been made more portable.
5152In generla, the code has been made 16-bit safe. Added Mark
5153Habersack's contributed DOS disk i/o routines.
5154
5155Miscellaneous portability fixes, including not depending on char's
5156being signed.
5157
5158The io_channel structure has a new element, app_data, which is
5159initialized by the ext2fs routines to contain a copy of the filesystem
5160handle.
5161
5162ext2fs_check_directory()'s callback function may now return the error
5163EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5164really do the checking, despite the presence of the callback function.
5165
5166
Theodore Ts'obc210071997-06-17 05:41:36 +00005167E2fsprosg 1.11 (June 17, 1997)
5168==============================
5169
5170Fixed e2fsck to detect (previously ignored) conflicts between the
5171superblock or block group descriptors and block bitmaps, inode
5172bitmaps, and inode tables.
5173
5174Fixed bug in e2fsck so that when the message printed out when a block
5175or inode bitmap conflicts with other data, it has the correct group
5176number.
5177
5178Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5179to badblocks. This meant that not all of the filesystem was being
5180tested for bad blocks!
5181
5182Fixed an array boundary overrun case which cropped up in
5183ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5184-b 4096".
5185
5186Adjusted the number of columns printed by mke2fs when displaying the
5187superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00005188really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00005189
5190Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5191dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5192fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5193
5194Programmer's notes:
5195-------------------
5196
5197Fixed install rule in lib/ss so that ss_err.h is actually getting
5198installed.
5199
5200Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5201bassed back to the caller.
5202
5203Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5204setting the current inode number (which meant this function wasn't
5205working at all).
5206
5207Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5208blocks in the bitmap when increasing the size of the bitmap.
5209
5210Changed the initial number of blocks allocated by ext2fs_init_dblist()
5211to be more realistic.
5212
5213Added a new function ext2fs_allocate_group_table, which sets up the
5214group descriptor information (and allocates inode and block bitmaps,
5215and inode tables for a particular group). The function was created by
5216factoring out code form ext2fs_allocate_tables().
5217
5218Added a new function ext2fs_move_blocks which takes a bitmap of the
5219blocks to be moved, and moves them to another location on the
5220boardboard.
5221
5222Make the unix_io channel's io_channel_flush implementation calls sync()
5223to to flush the kernel buffers to disk.
5224
5225Added a new function ext2fs_dblist_count returns the number of
5226directory blocks in dblist.
5227
5228
Theodore Ts'oae851481997-04-29 18:13:24 +00005229E2fsprogs 1.10 (April 24, 1997)
5230===============================
5231
5232Mke2fs once again defaults to creating revision #0 filesystems, since
5233people were complaining about breaking compatibility with 1.2 kernels.
5234Warning messages were added to the mke2fs and tune2fs man pages that
5235the sparse superblock option isn't supported by most kernels yet (1.2
5236and 2.0 both don't support parse superblocks.)
5237
5238Added new flag to mke2fs, -R <raid options>, which allows the user to
5239tell mke2fs about the RAID configuration of the filesystem. Currently
5240the only supported raid option is "stride" which specifies the width
5241of the RAID stripe.
5242
5243Fixed bug in e2fsck where pass1b would bomb out if there were any
5244blocks marked bad in the inode table.
5245
5246Fixed rare bug in mke2fs where if the user had a very unlucky number
5247of blocks in a filesystem (probability less than .002) the resulting
5248filesystem would be corrupt in the last block group.
5249
5250Fixed bug where if e2fsck tried to allocate a block to fix a
5251filesystem corruption problem and the filesystem had no free blocks,
5252ext2fs_new_block() would loop forever.
5253
5254The configure script now checks explicitly to see if "-static" works,
5255since that can't be assumed to be true --- RedHat doesn't install
5256libc-static by default.
5257
5258Fixed bug in libext2's block iterator functions where under some
5259cirmcustances, file with holes would cause the bcount parameter to the
5260callback function to be incorrect. This bug didn't affect any of
5261e2fsprogs programs, but it was discovered by Paul Mackerras, the
5262author of the PPC boot loader.
5263
5264Removed use of static variables to store the inode cache in libext2fs.
5265This caused problems if more than one filesystem was accessed via
5266libext2fs (static variables in libraries are generally a bad idea).
5267Again, this didn't affect e2fsprogs programs, but it was discovered by
5268Paul Mackerras.
5269
5270Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5271will compile cleanly with 1.2.13 kernels (even with a.out shared
5272libraries!)
5273
5274Programmer's notes:
5275-------------------
5276
5277Added new functions to duplicate an ext2 filesystem handle, and its
5278associated substructure. New functions: ext2fs_dup_handle(),
5279ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5280Other structures, such as the io_channel and the inode_cache, now have
5281a ref count so that they only get freed when they are no longer used
5282by any filesystem handle. (These functions were added as part of the
5283development effort for an ext2 resizer).
5284
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00005285E2fsprogs 1.09 (April 14, 1997)
5286===============================
5287
5288Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5289accidentally introduced in the 1.08 release. The overhead calculation
5290was accidentally removed, which caused ext2fs_initialize() to not
5291notice when the filesystem size needed to be adjusted down because
5292there wasn't enough space in the last block group.
5293
5294Fixed bug in version parsing library routine; it was always parsing
5295the library version string, instead of using the passed-in string.
5296
5297Clarified chattr man page.
5298
Theodore Ts'o24757fa1997-04-29 17:39:27 +00005299E2fsprogs 1.08 (April 10, 1997)
5300===============================
5301
5302E2fsck 1.07 was very slow when checking very large filesystems with a
5303lot of files that had hard links (i.e., news spools). This was fixed
5304by seriously revamping the icount abstraction. Added a formal test
5305suite for the icount abstraction.
5306
5307Debugfs now has a "-l" option to the "ls" command, which lists the
5308inode number, permissions, owner, group, size, and name of the files
5309in the directory.
5310
5311Fix a bug in e2fsck where when a directory had its blocks moved to
5312another location during the pass 1b processing, the directory block
5313list wasn't updated, so pass 2 wouldn't check (and correct) the
5314correct directory block.
5315
5316E2fsck will now treat inodes which contain blocks which are claimed by
5317the filesystem metadata by treating them as multiply claimed blocks.
5318This way, the data in those blocks can be copied to a new block during
5319the pass 1b--1d processing.
5320
5321E2fsck will attempt to determine the correct superblock number and
5322display it in the diagnostic and warning messages if possible.
5323
5324Add support for a new (incompatible) feature, "sparse_super". This
5325feature reduces the number of blocks which contain copies of backup
5326superblocks and block group descriptors. (It is only an incompatible
5327feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5328support a new -s option; e2fsck will recognize filesystems built with
5329this feature turned on.
5330
5331E2fsck now checks the library to make sure is the correct version,
5332using new library functions. (This helps to diagnose incorrectly
5333installed e2fsprogs distributions.)
5334
5335Dumpe2fs now prints more information; its now prints the the
5336filesystem revision number, the filesystem sparse_super feature (if
5337present), the block ranges for each block group, and the offset from
5338the beginning of the block group.
5339
5340Mke2fs now distributes the inode and block bitmap blok so that the
5341won't be concentrated in one or two disks in RAID/striping setups.
5342Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5343choose the largest blocks per group that be chosen. (For 2k blocks,
5344you can have up to 16384 blocks/group; for 4k blocks, you can have up
5345to 32768 blocks/group.) Previously mke2fs would not allow
5346specification of more than 8192 blocks per group, even if you were
5347using a 2k or 4k block group.
5348
5349Programmer's notes:
5350-------------------
5351
5352Added a new function ext2fs_create_icount2() which takes a "hint"
5353argument. This hint argument presets the icount array with the list
5354of inodes which actually need to be in the icount array. This really
5355helps to speed up e2fsck.
5356
5357Added a new function ext2fs_icount_validate() which checks the rep
5358invariant for the icount structure. This is used mostly for testing.
5359
5360The error mesasage given when a bad inode number is passed to
5361test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5362EXT2FS_UNMARK_ERROR).
5363
5364Added a new function ext2fs_set_dir_block which sets the block of a
5365dblist entry, given the directory inode and blockcnt.
5366
5367Added a new function ext2fs_get_library_version() which returns the
5368current library version, and ext2fs_parse_version_string() which
5369returns a version number based on a e2fsprogs version string.
5370
5371The icount functions will return EINVAL if the passed in inode number
5372is out of bounds.
5373
Theodore Ts'o21c84b71997-04-29 16:15:03 +00005374E2fsprogs 1.07 (March 9, 1997)
5375==============================
5376
5377E2fsck is now uses much less memory when checking really large
5378filesystems (or rather, filesystems with a large number of inodes).
5379Previously a filesystem with 1 million inodes required 4 megabytes of
5380memory to store inode count statistics; that storage requirement has
5381now been reduced to roughly half a megabyte.
5382
5383E2fsck can now properly deal with bad blocks appearing inside the
5384inode table. Instead of trying to relocate the inode table (which
5385often failed because there wasn't enough space), the inodes in the bad
5386block are marked as in use.
5387
5388E2fsck will automatically try to use the backup superblocks if the
5389primary superblocks have a bad magic number or have missing meta-data
5390blocks (or meta-data blocks which are out of range).
5391
5392E2fsck's pass 3 has been made more efficient; most noticeable on
5393filesystems with a very large number of directories.
5394
5395Completely revamped e2fsck's system of printing problem reports. It
5396is now table driven, to make them more easily customizeable and
5397extendable. Error messages which can be printed out during preen mode
5398are now one line long.
5399
5400Fixed e2fsck's filesystem swapping code so that it won't try to swap
5401fast symbolic links or deleted files.
5402
5403Fixed e2fsck core dumping when fixing a filesystem which has no
5404directories (not even a root directory).
5405
5406Added a check to e2fsck to make sure that the length of every
5407directory entry is a multiple of 4 (since the kernel complains if it
5408isn't).
5409
5410Added a check to e2fsck to make sure that a directory entry isn't a
5411link to the root directory, since that isn't allowed.
5412
5413Added a check to e2fsk to now make sure the '.' and '..' directory
5414entries are null terminated, since the 2.0 kernel requires it.
5415
5416Added check to write_bitmaps() to make sure the superblock doesn't get
5417trashed if the inode or block bitmap is marked as being block zero.
5418
5419Added checking of the new feature set fields in the superblock, to
5420avoid dealing with new filesystem features that this package wasn't
5421set up to handle.
5422
5423Fixed a fencepost error in ext2fs_new_block() which would occasionally
5424try to allocate a block beyond the end of a filesystem.
5425
5426When the UUID library picks a random IEEE 802 address (because it
5427can't find one from a network card), it sets the multicast bit, to
5428avoid conflicting with a legitimate IEEE 802 address.
5429
5430Mke2fs now sets the root directory's owner to be the real uid of the
5431user running mke2fs. If the real uid is non-zero, it also sets
5432the group ownership of the root directory to be the real group-id of
5433the user running mke2fs.
5434
5435Mke2fs now has more intelligent error checking when it is given a
5436non-existent device.
5437
5438When badblocks is given the -vv option, it now updates the block that
5439it is currently testing on every block.
5440
5441Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5442currently correctly if PATH wasn't already set.
5443
5444Shared libraries now built with dependencies. This allows the shared
5445library files to be used with dlopen(); it also makes the transition
5446to libc 6 easier, since ld.so can tell which libc a particular shared
5447library expects to use.
5448
5449Programmer's notes:
5450-------------------
5451
5452Added new abstraction (defined in dblist.c) for maintaining a list of
5453blocks which belongs to directories. This is used in e2fsck and other
5454programs which need to iterate over all directories.
5455
5456Added new functions which test to see if a contiguous range of blocks
5457(or inodes) are available. (ext2fs_*_bitmap_range).
5458
5459Added new function (ext2_inode_has_valid_blocks) which returns true if
5460an inode has valid blocks. (moved from e2fsck code).
5461
5462Added new function (ext2fs_allocate_tables) which allocates the
5463meta-data blocks as part of initializing a filesystem. (moved from
5464mke2fs code).
5465
5466Added a new I/O manager for testing purposes. It will either allow a
5467program to intercept I/O requests, or print debugging messages to
5468trace the activity of a program using the I/O manager.
5469
5470The badblocks_list functions now store the bad blocks in a sorted
5471order, and use a binary search to speed up badblocks_list_test.
5472
5473The inode scan function ext2fs_get_next_inode() may now return a soft
5474error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5475those cases where part of an inode table is missing or there is a bad
5476block in the inode table.
5477
5478Added a new function (ext2fs_block_iterate2) which adds new arguments to
5479the callback function to return a pointer (block and offset) to the
5480reference of the block.
5481
5482Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5483application to jump to a particular block group while doing an inode
5484scan.
5485
5486The badblocks list functions were renamed from badblocks_* to
5487ext2fs_badblocks_*. Backwards compatibility functions are available
5488for now, but programs should be modified to use the new interface.
5489
5490Some of the library functions were reorganized into separate files to
5491reduce the size of some programs which statically link against the
5492ext2 library.
5493
5494Put in some miscellaneous fixes for the Alpha platform.

5497E2fsprogs 1.06 (October 7, 1996)
5498================================
5499
5500Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5501smash the backup copies in ext2fs_close(). (The problem was that when
5502e2fsck -p discovered the problem, while it was closing the filesystem
5503and exiting, it was also blowing away the backup superblocks on the
5504disk, which was less than friendly.) We now make it the case that we
5505only write out the backup superblock and the back block descriptors if
5506the filesystem is completely free from problems.
5507
5508Fixed a bug in block_interate in the lib/ext2fs library which caused
5509e2fsck to fail on GNU Hurd-created filesystems.
5510
5511Add support for Linux/FT's bootloader, which actually uses
5512EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5513to clear the inode.
5514
5515Add support for the "A" (no atime update) attribute. (Note: this
5516attribute is not yet in production kernels.)
5517
5518The test suite is not automatically run when doing a "make all" from
5519the top level directory. Users should manually run "make check" if
5520they wish to run the test suite.
5521
5522Upon a preenhalt(), make the printed message more explicit that
5523running e2fsck "MANAULLY" means without the -p or -a options.
5524
5525In e2fsck, if a disconnected inode is zero-length, offer to clear it
5526instead of offering to connect it to lost+found.
5527
5528In e2fsck, if a filesystem was just unmounted uncleanly, and needs
5529e2fsck to be run over it, change e2fsck to explicitly display this
5530fact.
5531
5532For dumpe2fs and e2fsck, cause the -V option to print out which
5533version of the ext2fs library is actually getting used. (This will
5534help detect mismatches of using a 1.06 utility with a 1.05 library,
5535etc.)
5536
5537Programmers' notes:
5538-------------------
5539
5540EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
5541the naming convention.
5542
5543In ext2fs_initialize(), make sure the description for the inode bitmap
5544is correctly initialize.
5545
5546Fixed minor type typo in ext2fs_allocate_generic_bitmap();
5547
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00005548E2fsprogs 1.05 (September 7, 1996)
5549==================================
5550
5551Add support for new fields in the ext2 superblock --- volume name,
5552volume UUID, and last mounted field. Dumpe2fs displays these fields,
5553tune2fs and mke2fs allows you to set them. E2fsck will automatically
5554generate a UUID for those volumes that don't have them.
5555
5556Put in support for e2fsck to recognize HURD specific ext2 features ---
5557most notably, the translator block. The e2fsprogs tools will now use
5558the creator_os field in the superblock to correctly handle different
5559OS-specific variants of the ext2 filesystem.
5560
5561E2fsck now fixes inodes which have a the deletion time set, but which
5562have a non-zero i_link_count field by offering to clear the deletion
5563time. Previously e2fsck assumed that the inode was deleted (per 0.3c
5564ext2 kernel behavior) and offered to unlink the file.
5565
5566If e2fsck sets the clean bit, but nothing else, set the exit code
5567FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
5568set the filesystem valid bit when it was previously cleared. :-) This
5569was needed to make the HURD fsck driver happy.
5570
5571If the user refuses to attach an unattached inode, e2fsck will no
5572longer set the inode's link count. Otherwise, the inode would end up
5573getting marked as unused, which might cause loss of data later.
5574
5575Make the message issued by e2fsck when the superblock is corrupt less
5576confusing for users. It now mentions that another reason for the
5577"corrupt superblock" message might be that the partition might not be
5578an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
5579
5580Make the libext2 library more robuest so that e2fsck won't coredump on
5581an illegal superblock where the blocksize is zero. (f_crashdisk is
5582the test case).
5583
5584By default, create filesystems where the default checkinterval is 6
5585months (180 days). Linux servers can be robust enough that 20 reboots
5586can be a long, long time.
5587
5588Added configure flag --enable-old-bitops, which forces the bitops to
5589use the old (native) bitmask operations. By default on the sparc
5590platform, the standard ext2 bit ordering is now used.
5591
5592Added a new feature to e2fsck to byte-swap filesystems; this can be
5593used to convert old m68k filesystems to use the standard byte-order
5594storage for the superblock, inodes, and directory blocks. This
5595function is invoked by using the '-s' option to e2fsck.
5596
5597Debugfs's "dump" command has been enhanced so that it writes out the
5598exact size of the file so that the nulls at the end of the file are
5599eliminated. The command also accept a new "-p" option which will
5600attempt preserve to preserve the ownernship, permissions, and
5601file modification/access times.
5602
5603Debugfs has two new options, -f and -R. The -R option allows the user
5604to execute a single debugfs command from the command line. The -f
5605option allows the user to specify a "command file" containing debugfs
5606commands which will get executed.
5607
5608Dumpe2fs now pretty prints the check interval, instead of just
5609printing the check interval as a number of seconds.
5610
5611Fix bugs in debugfs: the params command when no filesystem is opened
5612no longer causes a core dump. It is now possible to unlink a file
5613when a pathame containing a '/' is specified.
5614
5615Tune2fs has a new -C option which sets the number of times the
5616filesystem has been mounted.
5617
5618Fix the chattr '-v' option so that it actually works. Chattr was
5619being buggy about the -v option parsing.
5620
5621Programmers' notes:
5622-------------------
5623
5624The directory lib/uuid contains a set of library routines to generate
5625DCE compatible UUIDs.
5626
5627Extended ext2fs_namei() to handle symbolic links. Added new function
5628ext2fs_nami_follow() which will follow last symbolic link in the case
5629where the pathname points to a sym link.
5630
5631The ext2fs_block_iterate function will now return the HURD translator
5632block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
5633iterator to return data blocks only. The ext2fs.h file now defines
5634constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
5635BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
5636count field of the iterator callback function.
5637
5638The test script driver now takes an optional second argument, which is
5639the test case to be run. This allows you to run a test case without
5640needing to run the entire test suite.
5641
5642On Linux ELF systems, install the .so files in the correct places
5643(/usr/lib). The .so files must be stored in the same directory as the
5644.a files.
5645
5646Fixed miscellaneous HURD compilation issues with header file being
5647included in the right order.
5648
5649Fixed debugfs so that it resets optind to zero, not one, since setting
5650optind to zero is more correct.
5651

Theodore Ts'oa4d09611997-04-29 14:28:00 +00005653E2fsprogs 1.04 (May 16, 1996)
5654=============================
5655
5656First "official" (1.03 was a limited release only) to support building
5657e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
5658kernels).
5659
5660This package includes a RPM specs file, that it can be built using the
5661RedHat Package Manager.
5662
5663E2fsck now prints a hint that if there are lots of incorrectly located
5664inode bitmaps, block bitmaps, and inode table blocks, the user might
5665want to try using e2fsck -b 8193 first, to see if that fares any
5666better.
5667
5668For ext2 filesystem written with the hurd, debugfs will now print out
5669the translator field when printing an inode structure.
5670
5671Lots of miscellaneous linking/installation cleanups:
5672
5673 Libraries are now linked using a relative pathname, instead of
5674 relying on -L working correct. It doesn't, in many cases, including
5675 current versions of GNU ld. This guarantees that the build tree is
5676 linking with the right libraries, instead of the ones installed in
5677 /usr/lib.
5678
5679 Header files, man pages, and the et/ss shell scripts are now
5680 generated using a custom substitution script, instead of relying on
5681 the configure script. This prevents needless recompilation of
5682 files; in addition, the custom substitution script is much faster.
5683
5684 e2fsck may now be linked dynamically, by using the
5685 --enable-dynamic-e2fsck flag to configure. This is not recommended,
5686 since it increases e2fsck's dependence on other files, but some
5687 people need to save disk space, and other critical programs on their
5688 systems were being linked dynamically anyway.
5689
5690 Programs such as fsck which didn't need to be linked against
5691 libext2fs (or mke2fs which didn't need to be linked against libe2p)
5692 only link against libraries they actually need. Otherwise, those
5693 programs would require the presense of libraries that otherwise
5694 could be removed from a rescuse diskette.
5695
5696 The ss include files are now installed correctly so they can
5697 actually be used by another package.
5698
5699 If the profiling libraries are built, they are now installed on a
5700 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00005703E2fsprogs 1.03 (March 27, 1996)
5704===============================
5705
5706Change the m68k bit numbering for bitmasks to match the bit numbering
5707used by all other ext2 implementations. (This change was requested by
5708the m68k kernel development team.)
5709
5710Support (in-development) filesystem format revision which supports
5711(among other things) dynamically sized inodes.
5712
5713Fixed a bug in the ext2 library so that an intelligent error is
5714returned if mke2fs is run with a ridiculously small number of blocks
5715for a partition.
5716
5717Fixed a bug in the ext2 library which required that the device be
5718openable in read/write mode in order to determine its size. This
5719caused e2fsck -n to require read/write access when it was not
5720previously necessary.
5721
5722Fixed a bug in e2fsck which casued it to occasionally fail the test
5723suite depending on which version of the floating point library it was
5724using.
5725
5726Fixed a bug in e2fsck so that it now halts with a fatal error when
5727certain superblock consistency checks fail. Previously it continued
5728running e2fsck, with some potential confusing/damaging consequences.
5729
5730Added new flag to fsck which allows the root to be checked in parallel
5731with other filesytems. This is not the safest thing in the world to
5732do, but some system administrators really wanted it.
5733
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00005734Fixed -Wall flames in lib/ss.
5735
Theodore Ts'o74becf31997-04-26 14:37:06 +00005736
5737E2fsprogs 1.02 (January 16, 1996)
5738=================================
5739
5740Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
5741
5742Change e2fsck to print statistics of how many non-contiguous files are
5743on the system. Note that a file which is larger than 8k blocks, it is
5744guaranteed to be non-contiguous.
5745
5746In mke2fs, print a warning message if a user tries to format a whole
5747disk (/dev/hda versus /dev/hda1). If a user really wants to format a
5748whole disk, the -F (force) option forces mke2fs to format a whole disk
5749as a filesytem.
5750
5751Fix a bug in fsck where in some cases it might start checking
5752partitions in the next pass before it finishes checking partitions in
5753the current pass. This still won't cause two partitions on the same
5754disk will be checked, so it's rarely a problem in real life.
5755
5756Patch lsattr so that it won't hang when checking a named pipe.
5757
5758Minor compilation fixes:
5759 * Fix the order of libraries that were linked in debugfs.
5760 * Allow the sources to be compiled with -ansi turned on.
