Theodore Ts'o7e2ec012006-04-22 04:29:16 -04001E2fsprogs 1.39-WIP (April 9, 2006)
Theodore Ts'o34a26112006-03-29 20:40:23 -05002===================================
3
4Dumpe2fs will now print the size of the journal (if present).
5
6Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
7between 2**31 and 2**32 blocks.
8
9Fix mklost+found so that it creates a full-sized directory on
10filesystems with larger block sizes.
11
12Fix a file descriptor leak in blkid library.
13
14Change mke2fs to use /etc/mke2fs.conf as a configuration file to
15configure the filesystem features, blocksize, and inode_ratio for
16different filesystem types.
17
18The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
19filesystem device node in exclusive mode to prevent accidents by
20system administrators. In the case of resize2fs and mke2fs, it will
21only use exclusive mode if the filesystem is not mounted.
22
23Fixed a bug in mke2fs which caused it to to fail when creating the
24resize inode for large filesystems. (Addresses Debian Bug #346580)
25
26Add support for on-line resizing to resize2fs.
27
28Fix blkid library so that logic to determine whether or not a device's
29cached information in /etc/blkid.tab needs to be verified or not
30doesn't get confused by a system clock which is insane (for example,
31if the battery is dead on a Macintosh running PPC Linux. (Addresses
32Red Hat Bug: #182188)
33
34The blkid library will now store the UUID of the external journal used
35by ext3 filesystems, so that in the future, the userspace mount binary
36can use this to find the location of the external journal and pass
37this information to the kernel.
Theodore Ts'of3227852005-12-31 16:45:29 -050038
39E2fsck will now consult a configuration file, /etc/e2fsck.conf to
Theodore Ts'o34a26112006-03-29 20:40:23 -050040control how various options should be handled. See the e2fsck.conf
41man page for more details. (Addresses Debian Bug: #150295)
Theodore Ts'of3227852005-12-31 16:45:29 -050042
Theodore Ts'o34a26112006-03-29 20:40:23 -050043E2fsck now prints an explanatory message when delaying a filesystem
44check when the system is running on battery. (Addresses Debian Bug:
45#350306)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040046
Theodore Ts'o4c02c412005-12-09 19:20:01 -050047E2fsck will detect if the superblock's last mount field or last write
48field is in the future, and offer to fix if so. (Addresses Debian Bug
Theodore Ts'of3227852005-12-31 16:45:29 -050049#327580) These problems will be fixed automatically in preen mode
50since Debian's boot sequence bogusly doesn't set the time correctly
51until potentially very late in the bootup process, and this can cause
52false positives which will cause users' systems to fail to boot.
53(Addresses Debian Bugs #343662 and #343645)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040054
Theodore Ts'o34a26112006-03-29 20:40:23 -050055E2fsck now checks to see if the superblock hint for the location of
56the external journal is incorrect, and if so, offer to update it.
57(Addresses Debian Bug: #355644)
58
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040059Fix e2fsck from segfaulting on disconnected inodes that contain one or
60more extended attributes. (Addresses Debian Bug: #316736, #318463)
61
Theodore Ts'o4c02c412005-12-09 19:20:01 -050062E2fsck will stop and print a warning if the user tries running a
63read/write badblocks test on a read-only mounted root filesystem.
64
Theodore Ts'of3227852005-12-31 16:45:29 -050065When resizing a file containing a filesystem, resize2fs will expand or
66truncate a file as necessary. (Addresses Debian Bug: #271607)
67
Theodore Ts'o4c02c412005-12-09 19:20:01 -050068Fix mke2fs so that it correctly creates external journals on
69big-endian machines (such as a S/390).
70
71Fix debugfs's set_inode_field command so it can properly set the frag,
72fsize, uid_high, gid_high, and author fields in the inode instead of
73silently failing, and so that setting the i_size actually sets i_size
74correctly.
75
76Add a new debugfs command, set_current_time, which sets fs->now so
77that regression test suites can repeatedly modify the filesystem's
78last_write fields.
79
Theodore Ts'o34a26112006-03-29 20:40:23 -050080Fix a bug in debugfs's icheck which would incorrectly report the owner
81of an extended attribute block.
82
Theodore Ts'o4c02c412005-12-09 19:20:01 -050083Fix a display bug in "badblocks -sv" so that the done message properly
84clears the block number at the end of the test. (Addresses Debian Bug
85#322231)
86
Theodore Ts'of2b74cd2005-08-22 01:20:23 -040087Allow fractional percentages to the -m option in mke2fs and tune2fs
88(Addresses Debian Bug: #80205)
89
90Use fstat/fstat64 in getsize.c if the the target is a regular file,
91instead of attempting to do a binary search. Fix some fd leaks in
92error cases.
93
Theodore Ts'o34a26112006-03-29 20:40:23 -050094Add support for device mapper library to the blkid library to ensure
95that the "best" (i.e., leaf) device is probed by the blkid library.
96
Theodore Ts'o4c02c412005-12-09 19:20:01 -050097Fix the blkid library so that it notices when an ext2 filesystem is
98upgraded to ext3.
99
100Improve the blkid's library VFAT/FAT detection; it now understands
101labels stored in the root directory, and is more paranoid about
102checking the FAT superblock values.
103
Theodore Ts'o34a26112006-03-29 20:40:23 -0500104Fixed a fd leak in the uuid library which was causing problems for the
105LVM tools. (Addresses Debian Bug: #345832)
106
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500107Add support for the reiser4 and software suspend partitions to the
108blkid library. Also add support for extract the label from iso9660
109filesystems.
110
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400111Fix a compile_et bug which miscount the number of error messages if
112continuations are used in the .et file.
113
114Add extra sanity checks to protect users from unusual cirucmstances
115where /etc/mtab may not be sane, by checking to see if the device is
116reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
117#319002)
118
Theodore Ts'o34a26112006-03-29 20:40:23 -0500119Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
120Bug: #343149, #341911, #300871, #316604, #316782, #330789)
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500121
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400122Fix use-after-free bug in e2fsck when finishing up the use of the
123e2fsck context structure.
124
Theodore Ts'o34a26112006-03-29 20:40:23 -0500125Fixed spelling mistakes, typos, and otherwise clarified man pages and
126documentation. (Addresses Debian Bugs: #329859, #322188, #316811,
127#312515, #351268, #357951, #347295, #316040)
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500128
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400129Fixed various Debian packaging issues --- see debian/changelog for
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500130details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
Theodore Ts'o7e2ec012006-04-22 04:29:16 -0400131#310428, #330737, #330736, #329074, #356293, #360046)
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400132
133Programmer's notes:
134-------------------
135
Theodore Ts'o7e2ec012006-04-22 04:29:16 -0400136Update config.guess and config.sub to latest version (2006-02-23) from
137FSF.
138
139Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
140Bugs: #360661, #360317)
141
Theodore Ts'o34a26112006-03-29 20:40:23 -0500142Fixed the Makefile so that they work correctly on newer versions of
143GNU make (i.e., 3.81).
144
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400145Add valgrind support to the regression test suites, and eliminate
146false positives from valgrind.
147
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500148Add a regression test suite for the blkid library.
149
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400150Fix a fencepost error in resize2fs caught by valgrind.
151
Theodore Ts'o4c02c412005-12-09 19:20:01 -0500152Fix compiler warnings about missing memcpy prototypes.
153
154We no longer have the sparc assembly code in the header file any more,
155so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
156break compiles on the sparc architectures when using gcc.
157
158In the libext2fs library, add the new field fs->now which if non-zero
159is used instead of the system time when setting various filesystem
160fields (last modified time, last write time, etc.)
161
162Fix gcc 4.01 complaints by adding a missing #include <string.h> to
163ext2fs.h which is needed since the inline functions use memcpy().
164(Addresses Sourceforge Bug #1251062)
165
166Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
167the build system when building files in the util directory which are
168needed during the build process. This avoids potential problems when
169cross-compiling and some of the options specified in CFLAGS or LDFLAGS
170are not recognized as valid by the host compiler. (Addresses
171Sourceforge Bug #1261547)
172
173Clean up the blkid library by making the superblock and generic i/o
174functions to be more generic. Clean up interface to the probe
175function, and fix memory leak. Finallly, remove an unneeded reference
176to probe.h in the lib/blkid/resolve.c
177
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500178Add an ext2fs_read_bb_FILE regression test to confirm proper detection
179of invalid block #'s.
180
Theodore Ts'o34a26112006-03-29 20:40:23 -0500181The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
182indicate that the the function read/writes the memory location.
183
Theodore Ts'o3285a9c2005-12-10 23:05:30 -0500184Fix various gcc -Wall complaints.
185
186Add a dependency to make sure that the subdirectories are created
187before creating all of the object files, in order to address parallel
188build problem in the library Makefiles. (Addresses Sourceforge Bug:
189#1261553)
190
191Add $(LDFLAGS) to the command line argument when generating an ELF or
192Solaris shared library, to allow cross-compile and other builds that
193might need to specify -L paths to needed libraries. (Addresses
194Sourceforge Bug #1261549)
195
Theodore Ts'of2b74cd2005-08-22 01:20:23 -0400196
Theodore Ts'ofea95ff2005-07-01 17:31:55 -0500197E2fsprogs 1.38 (June 30, 2005)
Theodore Ts'o1f965c82005-06-30 20:06:45 -0400198==============================
199
200Fix blkid's test programs (built with "make check") compile correctly
201even without "configure --enable-blkid-debug".
202
203Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
204type aliasing rules on newer gcc compilers. (Addresses Red Hat
205Bugzilla ##161183.)
206
207Fix com_err library to make it more compatible with recent changes
208made to the com_err library in MIT Kerberos V5 version 1.4.
209(Addresses Sourcefroge Bug #1150146)
210
211General cleanup of messages printed by e2fsprogs programs for grammar,
212consistency, and to make life easier for translators. Fixed a few
213strings containing English that had not been marked as needing
214translations. Removed strings that do not need to be translated, to
215make life easier for translators.
216
217Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
218test to see if a device appears to be in use instead of just relying
219on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
220
221Fix portability problem in the filefrag program affecting platforms
222where the size of an integer is smaller than the size of a long.
223(Addresses Debian Bug #309655)
224
225Mke2fs will now use a larger journal by default for filesystems
226greater than 4GB. (128 MB instead of 32MB).
227
228Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
229unless forced. This is to avoid signed vs. unsigned kernel bugs in
230block numbers that still need to be fixed.
231
232The blkid program has a new option which will more efficiently search
233for device when it is known (or expected) that only one matching
234device will be found in the system, such as when doing a lookup by
235UUID.
236
237Debian's e2fsprogs-specific initrd fragment will avoid including
238unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
239and LD_LIBRARY_PATH, and filtering out libraries found in
240/etc/ld.so.preload. (Addresses Debian Bug: #304003)
241
242Fixed a potential portability issue in the blkid programs for
243architectures where the char type is unsigned. (Addresses Sourceforge
244Bug: #1180585)
245
246Fix a bug in filefrag so that it doesn't falsely count an extra
247discontinuity when the first block found is an indirect block.
248(Addresses Debian Bug #307607).
249
250Fix blkid's recognition of cramfs filesystems, and enhance it to be
251able to handle cramfs labels.
252
253Fix debugfs's stat command to not core dump when a filesystem is not
254open.
255
256Fix e2fsck's handling of error conditions caused by the resize inode
257claiming blocks that are also used by other inodes, a filesystem
258corruption which was commonly caused by a bug in Fedora Core 3's
259resize2fs program.
260
261Fixed bug in filefrag which caused it to fail on non-ext2/3
262filesystems. (Addresses Debian Bug: #303509)
263
264If the superblock last mount time indicates that the system clock may
265not be accurate, then e2fsck will omit checking inodes' deletion time
266field for indications of a potential corrupted orphaned inode list.
267(Previously e2fsck only ommited these LOW_DTIME checks when the
268superblock's last write time looked insane.)
269
270Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
271(Addresses Debian bug #302200)
272
273Make the blkid library more paranoid about being run from setgid
274programs, and to use __secure_getenv() from libc if it is available.
275
276Fixed spelling mistakes, typos, and otherwise clarified man pages.
277(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
278and Sourceforge Bug: #1189803)
279
280Updated and fixed translations.
281
282Fixed various Debian packaging issues --- see debian/changelog for
283details.
284
285Programmer's notes:
286-------------------
287
288Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
289changed to take an unsigned int for the bit number. Negative bit
290numbers were never allowed (and didn't make any sense), so this should
291be a safe change. This is needed to allow safe use of block numbers
292greater than or equal to 2**31.
293
294The compile_et program will avoid recreating generated foo_err.c and
295foo_err.h files if no changes are necessary. The compile_et program
296will also atomically replace these files to avoid a potential parallel
297build race problem on SMP systems. (Addresses Sourceforge Bug:
298#1157933)
299
300Added a new function to the blkid library, blkid_probe_all_new(),
301which only probes newly added disk devices, and change
302blkid_find_dev_with_tag() to use this function so that when a
303requested tag is not found, devices that were previously not checked
304are searched before searching all devices in the system.
305
306Added new functions to the blkid library, blkid_dev_set_search() and
307blkid_dev_has_tag().
308
309E2fsck's problem strings can now use @m and @n as abbrevations for
310"multiply-claimed" and "invalid", respectively.
311
312The e2fsprog.pot file now has an explanation of how the @-expansion
313and %-expansion works, and strings in e2fsck/problem.c which contain @
314characters now have comments in e2fsprogs.pot with the @-expansion to
315make life easier for translators.
316
317Fixed missing return values in the ext2fs library which could cause it
318to return random garbage in certain error conditions.
319
320Allow the current time to be overriden via the E2FSCK_TIME environment
321variable for use in regression tests.
322
323The test scrpit driver program now exits with a non-zero status if
324there any of its test that it ran failed.
325
326Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
327Bug: #1157933)
328
329Fixed "make check" so that it compiles correctly even when e2fsprogs'
330header files have not be installed in the system include directories.
331(Addresses Sourceforge Bug: #1180572)
332
333Fixed gcc -Wall nits.

Theodore Ts'ofd4b28e2005-03-21 22:37:03 -0500336E2fsprogs 1.37 (March 21, 2005)
337===============================
338
339Add support for checking the validity of Extended Attributes stored in
340inodes to e2fsck.
341
342Add support for dumping the contents of large inodes to debugfs,
343including the extended attributes stored in inodes.
344
345Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
346when we create a new inode we make sure that the extra information in
347the inode (any extra fields in a large inode and any ea-in-inode
348information) is initialized correctly. This can take place when
349mke2fs creates the root and lost+found directory, when e2fsck creates
350a new root inode or a new lost+found directory, and when the user uses
351the debugfs write, mknod, or mkdir commands. Otherwise, the newly
352create inode could inherit garbage (or old EA information) from a
353previously deleted inode.
354
355Fixed a bug in e2fsck so it would notice if a file with an extended
356attribute block was exactly 2**32 blocks, such that i_blocks wrapped
357to zero.
358
359Added support to filefrag to detect files which are using the new
360experimental file extents format, and use the non-ext2 algorithm in
361that case. Fixed a bug to avoid reporting a false discontinuity if
362there is one or more unallocated blocks at the beginning of a file.
363
364Duplicated a check for noticing whether or not the number of blocks
365(given a certain blocksize) is greater than 2**32 when the
366BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
367allows mke2fs to automatically use a larger blocksize when creating a
368filesystem on a very large device when run on systems that do not
369support BLKGETSIZE64.
370
371Fix the I18N build which was broken in e2fsprogs 1.36 because the
372build system had been switched to treat the .gmo files as shipped
373files (for backwards compatibility with systems that have older GNU
374I18N tools installed), but the gen_tarball.in script was still
375removing the .gmo files from the official source distribution.
376
377Fixed various Debian packaging issues --- see debian/changelog for
378details. (Addresses Debian Bugs ##296769, #299341)
379
380Programmer's notes:
381-------------------
382
383Added new functions to the e2p library which convert between a string
384and os_type: e2p_os2string() and e2p_string2os(), and used them to
385make the generated binaries more compact.
386
387Fixed a compile-time error on Darwin systems.
388
389Cleaned up the lib/ext2fs Makefile slightly.

Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500392E2fsprogs 1.36 (February 4, 2005)
393=================================
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500394
395All of the patches that were applied to Fedore Core 3's
396e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
397lot of bug fixes first. Users of Fedora Core 3 are strongly
398encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
399
400Add support for filesystem with the online resizing via resize inode
401feature. Fixed numerous bugs from the Fedora patches. The Fedora
402patches also didn't bother to do any consistency checking on the
403resize inode, or add any tests to the regression test suite. The "-R
404resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
405being listed in mke2fs's usage message. All of these shortcomings
406have been corrected.
407
408E2fsck can also also fix filesystems trashed by Fedora's resize2fs
409program. In order to do this, the user must run the commands:
410
Theodore Ts'od0a3b462005-05-05 22:57:44 -0400411 debugfs -w /dev/hdXXX -R "features ^resize_inode"
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500412 e2fsck -f /dev/hdXXX
413
414Optionally, the ext2prepare command can be used to re-enable online
415resizing after the filesystem has been fixed.
416
417The fsck program will now accept an optional filedescriptor argument
418to the -C option. (The Fedora version of this patch would sometimes
419cause fsck to ignore a parameter on fsck's command line in some rare
420cases, sigh.)
421
Theodore Ts'odc256972005-01-26 13:20:12 -0500422Make sure e2fsprogs doesn't write garbage into the reserved portion of
423large inodes.
424
425Make sure resize2fs releases the blocks belonging to the old inode
426table blocks when moving the inode table. (Addresses Debian Bug:
427#290894)
428
429Skip the r_resize_inode test if resize2fs is not compiled (due to
430configure --disable-resizer)
431
432E2fsck now checks the summary filesystem accounting information, and
433if any of the information is obviously wrong, it will force a full
434filesystem check. (Addresses Debian Bug #291571)
435
436Fix e2fsck to not complain when the resize_inode feature is enabled,
437s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
438the resize inode.
439
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500440Fix e2fsck to note delete symlinks that contain an extended attribute
441after the ext_attr feature flag has been cleared. (Addresses Red Hat
442Bugzilla #146284).
443
Theodore Ts'odc256972005-01-26 13:20:12 -0500444Add new utility program, copy_sparse.c, which is very useful
445for dealing with large sparse files (such as e2image files).
446
447Add support for jnl_blocks[] for debugfs's set_super_value.
448
449Fix filefrag so that it works correctly with sparse files.
450
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500451Filefrag -v will print first and last blocks.
452
Theodore Ts'odc256972005-01-26 13:20:12 -0500453Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
454and dumpe2fs.
455
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500456Add mke2fs support so that it can support filesystems larger than 4TB
457automatically, by retrying with a 4k blocksize if the device size is
458too big to be expressed using a 1k blocksize. (Addresses Sourceforge
459bug #1106631)
460
Theodore Ts'odc256972005-01-26 13:20:12 -0500461Change blkid to test for NTFS first because Windows sometimes doesn't
462clear enough of the parition to confuse the probing routines into
463thinking the old filesystem type is still valid. (Addresses Debian
464Bug #291990)
465
Theodore Ts'o66fa0de2005-01-11 14:39:55 -0500466Add support for swap partition label and uuid's in the blkid library.
467
Theodore Ts'odc256972005-01-26 13:20:12 -0500468Add support to the blkid library to recognize Oracle ASM volumes.
469
470Make blkid -t display all devices that match the specified criteria,
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500471not just the first one, and work more consistently when the blkid
472cache file is not available or set to /dev/null. (Addresses Debian
473Bug #290530 and #292425)
Theodore Ts'odc256972005-01-26 13:20:12 -0500474
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500475Badblocks will now correctly display block numbers greater than
476999,999,999 in its progress display.
477
478The tune2fs program will not allow the user from setting a ridiculous
479number of reserved blocks which would cause e2fsck to assume the
480superblock was corrupt. E2fsck's standards for what is a ridiculous
481number of reserved block has also been relaxed to 50% of the blocks in
482the filesystem.
483
484The blkid library will return vfat in preference to msdos, and ext3 in
485preference to ext2 (if the journalling flag is set) so that mount will
486do the right thing. (Addresses Debian bug #287455)
487
488Mke2fs will now use the -E option for extended options; the old -R
489(raid options) option is still accepted for backwards compatibility.
490Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
491
492Mke2fs will now accept a size in megabytes, gigabytes, and other units
493(via "32m" or "4g" on the command line) if the user finds this more
494convenient than specifying a block count.
495
496Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
497cache conherency problem.
498
499Debugfs now supports a new command, set_inode_field, which allows a
500user to manually set a specific inode field more conveniently, as well
501as set entries in the indirect block map.
502
503Debugfs's set_super_value command has been enhanced so that the user
504can set most superblock fields, including the date/time fields and
505some of the more newsly added superblock fields.
506
507E2fsprogs programs now accept an offset to be passed to the file
508specifiers, via the syntax: "/tmp/test.img?offset=1024".
509
510E2fsprogs programs will now accept blocksizes up to 65536; kernel
511support on the x86 doesn't exist for now, but it can be useful on
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500512other architectures with page sizes greater than 4k. There are 2.6
513kernel patches out there which enable this, but they are of this
514writing still experimental.
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500515
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500516The e2image command now takes the -s option which will scramble
517directory entries for raw image files.
518
519Fix a file descriptor leak in the filefrag program.
520
521Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
522present.
523
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500524Fix bug in debugfs where kill_file would lead to errors when deleting
525devices and symlinks. (Sourceforge Bugs #954741 and #957244)
526
527Fix bug in the blkid library when detecting the ocfs1 filesystem
528
529Remove obsolete EVMS 1.x and a.out DLL support.
530
531E2fsck will attempt to recover from a journal containing illegal blocks.
Theodore Ts'o48301122004-09-19 08:23:41 -0400532
533Fixed two potential ordering constraint problems in e2fsck which might
534cause the filesystem to be corrupted if e2fsck is interrupted during a
535(extremely narrow) race window. Thanks to Junfeng Yang from the
536Stanford Metacompilation group for pointing this out.
537
538Fixed bug in e2fsck where it would not accurately detect whether or
539not the system is running on adaptor if the ACPI device representing
540the AC adapter didn't correspond to the what was used on IBM
541Thinkpads.
542
543Change e2fsck to accept directories greater than 32MB.
544
545Fix e2fsck so that a checkinterval of zero disables a time-based check
546of the filesystem.
547
548Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
549to the PAGER environment variable. (Addresses Debian Bug #239547)
550
551Tune2fs will not mark rewrite the superblock if the feature bitmasks
552are not modified.
553
554The debugfs program will set the filetype information when creating a
555link.
556
557Add debugfs -d option to use a separate source of data blocks when
558reading from an e2image file.
559
560Add e2image -I option which allows the e2image metadata to be
561installed into a filesystem.
562
563Fixed bug in the badblocks program which caused "done" to always
564appear in english even when a translation was available. (Addresses
565Debian Bug #252836)
566
567The blkid program has a new option -o which controls the output format
568of the blkid program; this is makes blkid more convenient to use in
569shell scripts.
570
571Fix a minor bug in uuid library, which was not using the full 14 bits
572of clock sequence when generating UUID's.
573
574Fix a Y8.8888K problem in the uuid library.
575
576Logsave now creates a new session id for itself to avoid getting
577killed by init whan transitioning between init levels.
578
579Change the licensing of the UUID library to be the 3-clause BSD-style
580license; this allows Apple to use the uuid library in Darwin.
581
582Add ocfs and ocfs2 probe support into the blkid library.
583
584Fix a memory and file descriptor leak in the blkid library.
585
586The blkid library will revalidate the device if the system time is
587earlier than last verification time of the device, since that
588indicates that the system time is probably nottrustworthy.
589
590The blkid library will override the default location of the blkid.tab
591file by the BLKID_FILE environment variable, if it is available.
592
593Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
594
595Add various portability fixes for lame new versions of glibc, Darwin
596and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500597Bugs #239934, #264630, #269044, #255589, #289133)
598
599Add support for Windows 9x/NT under Cygwin.
Theodore Ts'o48301122004-09-19 08:23:41 -0400600
601Updated and clarified various man pages. (Addresses Debian Bugs #236383,

Theodore Ts'o48301122004-09-19 08:23:41 -0400603
604Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
605
606Update the rpm spec files so that it works better with Fedora core 2
607and RH9.
608
609Fixed various Debian packaging issues (see debian/changelog). In
610particular, fixed the Debian initrd scripts. (#241183, #248050,
611#253595, #247775)

614Programmer's notes:
615-------------------
616
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500617Fixed various gcc -Wall warnings.
Theodore Ts'o48301122004-09-19 08:23:41 -0400618
619The uuid library now has new functions uuid_unparse_upper() and
620uuid_unparse_lower() which forces the case of the hex digits to be
621upper case, or lower case.
622
623The build process has been speeded up by enhancing the subst program
624to update the modtime on the generated files even when the generated
625file hasn't changed.
626
627The uuid library now uses C99 stdint.h types instead of custom types.
628
629Updated config.guess and config.sub with newer versions from the FSF.
630
631Removed out of date .cvsignore files from the source distribution.
632
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500633The ext2fs_unlink() function will return an error if both the name and
634inode number are unspecified, to avoid doing something surprising
635(such as unconditionally deleting the first directory entry).
636Directory entries are now deleted by coalescing them with the previous
637directory entry if possible, to avoid directory fragmentation. This
638is not an issue with the e2fsprogs suite, but may be a problem for
639some of the users of libext2fs, such as e2tools.
640
641Add support for version numbers of the form "1.36-rc1".
642
Theodore Ts'o48301122004-09-19 08:23:41 -0400643Fix build of mke2fs.static.
644
Theodore Ts'odc256972005-01-26 13:20:12 -0500645Add basic ext2fs library support for large (EA in inode) inodes.
646
Theodore Ts'o48301122004-09-19 08:23:41 -0400647The test_io mechanism can now abort after n reads or writes to a
648particular block. The block is specified by TEST_IO_BLOCK environment
649variable, and the read/write count by the TEST_IO_READ_ABORT and
650TEST_IO_WRITE_ABORT environment variables. The block data is now only
651dumped if the 0x10 bit is set in TEST_IO_FLAGS.
652
653UUID_DEFINE() in the uuid library now creates a static variable, with
654__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
655be used in header files.
656
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500657Add support for the install-strip and install-shlibs-strip targets, as
658suggested by the GNU coding guielines. "make install" no longer
659strips the binaries which are installed.
660
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500661Remove support for the --enable-old-bitops configure option which was
662only for very old sparc systems.
663
664Remove support for --enable-clear-htree; this was only needed during
665the early development of the htree patch.
666
Theodore Ts'o2b0dc0a2005-01-09 15:53:09 -0500667Use Linux-kernel-style makefile output so it is easier to see compiler
668warnings.
669
670Update gettext files to version 0.14.1.
671
672Update to use autoconf 2.5x.
673
674Improved support for compiling e2fsprogs under dietlibc.
675
Theodore Ts'o4ee558f2005-01-19 02:20:04 -0500676Make e2fsprogs portable to Solaris and FreeBSD systems.
677
Theodore Ts'o8ceb55f2005-01-28 12:33:01 -0500678Add blkid_verify(), blkid_get_library_version(), and
679blkid_parse_version_string() functions to the blkid library.
Theodore Ts'odc256972005-01-26 13:20:12 -0500680
681Add pkg-config files for e2fsprogs's libraries.
682
683Fix "make uninstall" to so that it removes everything that is installed.
684
Theodore Ts'o3eee5e92005-02-05 18:26:03 -0500685Add a configure --enable-maintainer-mode option which enables the
686makefile rules to rebuild the configure script from configure.in, and
687to reubuild the .gmo files in po directory.
688
689Drop the sparc assembly bitwise operations; it's less efficient
690than the GCC 3.4 compile code and triggers compiler warnings on
691sparc64. Thanks to Matthias Andree for his analysis and suggestions.

Theodore Ts'ob70b1162004-02-28 10:52:35 -0500695E2fsprogs 1.35 (February 28, 2004)
696==================================
697
Theodore Ts'o48301122004-09-19 08:23:41 -0400698E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500699preserves the existing badblocks list.
700
Theodore Ts'o48301122004-09-19 08:23:41 -0400701Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500702
703E2fsprogs will now deal correctly with symlinks that contain
704extended attribute information, which can be created using SE Linux.
705(Addresses Debian Bug #232328)
706
707Remove a double longjump into an invalid stack frame bug in e2fsck.
708(This was during an abort sequence, which normally worked on Linux and
709caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500710
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500711Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
712(the NLS library will replace "" with the .po header information).
713
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500714Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
715dump due to a division by zero error. (Addresses Debian bug #207082)
716
Theodore Ts'o151a7162003-12-26 14:04:33 -0500717Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
718when reconnecting a directory requires creating a lost+found
719directory. (Addresses Debian bug #219640).
720
721Fixed a bug where e2fsck would bomb out if a journal needed to be
722replayed when using an alternate superblock.
723
Theodore Ts'o48301122004-09-19 08:23:41 -0400724E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500725if the laptop is running on battery. The next time fsck runs while
726the system is on the AC mains, or after the grace period is exceeded,
727the filesystem will be checked. (Addresses Debian bug #205177)
728
729E2fsck will inform the user when there are 5 or fewer mounts before a
730filesystem check will be forced. (Addresses Debian bug #157194)
731
732Fix e2fsck's handling of corrupted indirect blocks in the bad block.
733We now correctly handle the case where there is an overlap between a
734block group descriptor or a superblock and a bad block indirect block.
735In the case where the indirect block is corrupted, we now suggest
736"e2fsck -c".
737
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500738Fix byte swap bugs in e2fsck that caused the journal backup location
739in the superblock and symlinks created by SE Linux to be cleared
740by e2fsck on big-endian machines. (Addresses Debian bug #228723)
741
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500742E2fsck -c now replaces the current list of bad blocks with the ones
743found by badblocks.
744
745Fix bugs in e2fsck and tune2fs which could cause a core dump if a
746non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
747
748Fix a potential bug in e2fsck which could cause it to core dump when
749trying to print the location of the backup superblock.
750
751Protect against a potential core dump in e2fsck when printing a
752message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400753
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400754Add support for backing up the journal inode location in the
755superblock. E2fsck will automatically save the journal information in
756the superblock if it is not there already, and will use it if the
757journal inode appears to be corrupted. ext2fs_add_journal_inode()
758will also save the backup information, so that new filesystems created
759by mke2fs and filesystems that have journals added via tune2fs will
760also have journal location written to the superblock as well.
761Debugfs's logdump command has been enhanced so that it can use the
762journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500763
764E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400765
766Shrink the size of the e2fsck executable by moving some initialized
767variables to the BSS segment.
768
769E2fsck will avoid printing the ^A and ^B characters which bracket the
770progress bar when stdout and stdin are a tty device instead of a pipe
771to another program. (Addresses Debian bug #204137)
772
Theodore Ts'o151a7162003-12-26 14:04:33 -0500773Debugfs's mkdir command will automatically expand the directory if
774necessary. (Addresses Debian Bug: #217892)
775
776Fixed a bug in debugfs so that copying a file from /dev/null uses the
777correct mode bits. (Addresses Debian Bug: #217456)
778
779If the environment variables DEBUFS_PAGER and PAGER are not set,
780debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -0500781/usr/bin/pager, and then falling back to 'more' and 'less'.

783
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500784Debugfs will now support 2.6 device numbers where the major or minor
785number may be larger than 255. (Addresses Sourceforge bug #865289)
786
Theodore Ts'o48301122004-09-19 08:23:41 -0400787Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)

Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400792Fix regression tests so they work correctly when e2fsprogs is compiled
793with configure --disable-htree.
794
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500795Fix bug in uuid library when there is no network card and the library
796is generating a time-based uuid. The random MAC address was not
797correctly generated to be a multicast address.
798
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400799Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -0400800around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400801
802Fix bug in badblocks when using O_DIRECT; we need to make sure that
803we're reading from an offset which is page aligned. For read-only and
804read-write tests, we try to recover after an error so that we can
805continue reading on page-aligned boundaries. (Addresses Debian Bug
806#203713)
807
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500808Badblocks now checks 64 blocks at a time instead of 16. (Addresses
809Debian bug #232240)
810
Theodore Ts'o151a7162003-12-26 14:04:33 -0500811Updated and clarified various man pages. (Addresses Debian Bug
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500812#206845, #222606, #214920, #232406)

818Programmer's notes:
819-------------------
820
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500821Fixed a build problem so that e2fsprogs would compile with the
822--enable-profile option to configure selected. (Addresses Sourceforge
823bug #811408)
824
825Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
826Bugzilla Bug #112448)
827
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500828Centralize code which calculates the location of the superblock
829and block group descriptors so that it is in a single library routine.
830
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400831Added two new functions, ext2fs_file_open2() and
832ext2fs_inode_io_intern2() which take a pointer to an inode structure.
833
834Fix compile_et to output the correct prototype for
835initialize_xxx_err_table_r() in the header file. (Addresses Debian
836bug #204332)
837
838In the lib/et makefile, make sure com_err.info is deleted on "make clean".
839
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400840Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
841present. This is for when we try stuffing an int into void * pointer.
842
843Fix type-punning which can cause gcc 3.x to miscompile code by getting
844confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
845and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
846**'. The EVMS code uses an ugly union approach since we don't want to
847modify the EVMS interfaces.
848
849Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
850aid build process on systems can use invoke GNU make as "gmake".
851
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500852Added regression testing for mke2fs.
853
854Fixed gcc -Wall nitpicks.
855
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500856Fixed various compiler warnings.
857
858Add portability fixes for FreeBSD and for using fsctl under Darwin to
859support ext2 ioctl's.
860
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400861
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400862E2fsprogs 1.34 (July 25, 2003)
863===============================
864
865Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
866a tight loop while waiting for a child fsck to exit in some cases.
867This burns CPU times which slows down the low-level filesystem check.
868
869Added code to mke2fs to assure that the default block size for a
870filesystem is at least as big as the sector size of the device, if it
871can be determined.
872
873Changed mke2fs and resize2fs to round the default size of a filesystem
874to be an even multiple of the VM pagesize in order to avoid a Linux
875kernel bug introduced when the storage of the buffer cache was moved
876into the page cache.
877
878Mke2fs will warn the user when creating a filesystem with journaling
879and a blocksize greater than 4096. (Addresses Debian bug #193773)
880
881Fixed a bug in resize2fs which caused it to fail on filesystems with a
882non-empty bad block list. Resize2fs now discards any blocks on the
883badblock list which are no longer part of the filesystem as the result
884of a filesystem shrink. (Note: this means that shrinking and then
885enlarging a filesystem is no longer a reversible operation;
886information about bad blocks in the part of the filesystem which is to
887be chopped off will be lost.)
888
889Changed resize2fs so the user can use prefixes to specify the units of
890the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
891and to make the error and informational messages explicitly display
892the blocksize used by the filesystem, in order to avoid confusion.
893(Addresses Debian bug: #189814)
894
895Added a new debugfs command, dump_unused, which dumps the contents of
896all unused blocks to stdout. (Useful as an emergency try-to-find
897deleted data command.)
898
899Added a new debugfs command, imap, which prints the location of a
900specified inode in the inode table.
901
902Fixed a bug in the badblocks program which caused it to use one bit of
903randomness in its non-destructive read/write test, instead of using a
904full 8 bits of randomness.
905
906Added a new option (-t) to badblocks, which allows the user to control
907the test pattern(s) used when checking a disk.
908
909The blkid probe function now more correctly detects UDF filesystems.
910
911Fixed a bug in the blkid library which caused it to not update its
912cache if a filesystem changes from having a label to not having a
913label.
914
915Fixed a bug in the blkid library wihch could avoid an infinite loop
916in blkid_find_dev_with_tag() if /proc is not mounted and there the
917/etc/blkid.tab file has not yet been created.
918
919Fixed the badblocks program so that the destructive read/write test
920honors the -c option, and to use O_DIRECT when possible to avoid
921thrashing the system block buffer cache.
922
923Fixed various NLS issues.
Theodore Ts'oc8a40402005-06-05 16:42:20 -0400924 - Added Czech and Swedish translations
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400925 - Removed testing NYC translation
926 - Fixed NLS support for message abbrevations in e2fsck
927 - Remove de-utf.po, since we shouldn't have two versions using different
928 charset encodings.
929 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
930 simplify the statistics reporting in e2fsck.
931
932Changed configure.in so that its defaults for *BSD systems no longer
933build an fsck wrapper, and not to install in /usr/local by default.
934
935Fixed some minor spelling errors/typo's in e2fsck and the configure
936script.
937
938Fixed various Debian packaging issues (see debian/changelog).
939
940Updated and clarified man pages. (Addresses Debian Bug #195616)
941
942Programmer's notes:
943-------------------
944
945Fix gcc -Wall nitpicks.
946
947Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
948NLS support by default. (Added partial workaround for gettext/Darwin
949incompatibility problems.)
950
951Added full MIT KRB5 and Himdall compaibility support to the com_err
952library and the compile_et program. (Addresses Debian bug #191900)
953
954Added the blkid_known_fstype() function to the blkid library, which
955returns true if it is passed a filesystem type which is recognized by
956the blkid probing functions.
957
958Improved the documentation for the blkid library.
959
960Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
961returns the hardware sector size of a device, if it is available.
962
963Added a dependency in the blkid library's .so file to the uuid
964library, since the former uses the latter. (Addresses Debian bug
965#194094)
966
967Added --with-diet-libc and --disable-evms to the configure script.
968
969Fixed a minor memory leak in the badblocks program.
970
971Fixed a portability problem in tune2fs --- not all systems have strptime().
972
973Fixed a portability problem in debugfs with the use of getopt() more
974than once. Old-style BSD, new-style BSD, and Linux C libraries all do
975things differently.
976
977Add support Windows support to ext2fs_get_device_size().
978
979Added (normally disabled) debugging code to the Unix I/O manager which
980causes it to disable all userspace caching if the NO_IO_CACHE is
981defined.
982
983Changed the test I/O manager so it can always be linked into e2fsck,
984mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
985configure script. The test I/O manager will only print any debugging
986information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
987variables are set, which specifies which I/O operations are logged and
988a block number to watch, respectively. The log messages are sent to
989stderr by default, unless a filename is specified via the
990TEST_IO_LOGFILE environment variable.
991

Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400993E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400994===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500995
Theodore Ts'oba142c12003-04-16 00:59:59 -0400996Added a new utility program, logsave, which captures the output of a
997command in a log file, even if the containing directory hasn't been
998mounted yet (in which case the it saves the output in memory until it
999can write out the logfile). This is useful for capturing the
1000output of fsck during the boot sequence.
1001
1002Fixed some portability problems that were causing problems under
1003the Cygwin32 environment.
1004
1005Mke2fs now interprets a negative number to the -b option as a minimum
1006block size.
1007
1008Fixed a bug in mke2fs which was incorrectly checking the argument to
1009the -g option if the default block size was used. (Addresses Debian
1010bug #188319)
1011
1012Fsck now explicitly ignores tmpfs and devpts, and it will complain if
1013it can not find filesystem checkers for jfs, reseirfs, and xfs.
1014
1015E2fsck now updates the global free block and inode counters from the
1016block group specific counters quietly. This is needed for an
1017experimental patch which eliminates locking the entire filesystem when
1018allocating blocks or inodes; if the filesystem is not unmounted
1019cleanly, the global counts may not be accurate.
1020
1021Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
10222.0 is not yet supported; this only pulled in the bug fixes: fixed
1023possible hangs caused by bugs in calling waitpid, and not setting the
1024pipe to non-blocking mode; also fixed a file descriptor leak; made
1025sure all functions call log entry/exit functions.)
1026
1027Badblocks now flushes its output file as bad blocks are discovered.
1028
1029The uuid library is now more paranoid about assuming the correctness
1030of the /dev/random device; it mixes in a stream of bytes from
1031random/srandom, just in case.
1032
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001033Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -04001034maintainer of e2fsprogs. Other various Debian-specific packaging
1035cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001036
1037Move the source tarball generation functions from the top-level
1038makefile to the util/gen-tarball script.
1039
1040Updated the Turkish .po translation file.
1041
Theodore Ts'o1daf7582004-01-31 22:33:16 -05001042Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -05001043it more compatible with com_err libraries from those distributions.
1044
1045Changed dumpe2fs to always display the superblock fields relating to
1046the journalling and/or directory indexing feature even if those
1047features are not enabled.
1048
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001049Updated and clarify copyright statement vis-a-vis alpha releases of
1050e2fsprogs.
1051
1052The ss library will now try to dynamically link to the readline
1053library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -04001054the debugfs program now has line editing and history features. The
1055SS_READLINE_PATH environment variable is used to find a readline or
1056readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001057
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001058E2fsck now finds most duplicate filenames (all when rebuilding all
1059directories via the -D option) and offers to delete or rename
1060duplicate filenames/directory entries. (Addresses Debian Bug #176814).
1061
1062Fix bug in e2image. When writing out a raw image file, include data
1063blocks from symlinks that do not store the symlink within the inode.
1064
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001065Fix bug in resize2fs which incorrectly moved the block and inode
1066bitmaps for sparse superblock filesystems and incorrectly marked
1067blocks as in use. (Addresses Debian bug #174766)
1068
1069Added a new shared library, the blkid library, which efficiently
1070allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
1071and UUID filesystem specifiers without needing to search all of the
1072devices in the system. Instead, the device is looked up in a cache
1073file, and then verified to make sure the blkid cache is correct.
1074
1075Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
1076the device name, using the blkid library. (Addresses Debian bugs
1077#166048, #179671)
1078
1079Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1080used for spaces in device labels.
1081
1082Removed 32-bit limitations for debugfs's dump command.
1083
1084If the user specifies a large number of inodes, Mke2fs will
1085automatically adjust the number of blocks per group to find a valid
1086set of filesystem parameters.
1087
1088Add workaround to detect broken MD devices where when some of the
1089underlying devices are marked read-only, writes to the MD device are
1090silently dropped. E2fsck will detect if there is an attempt to run
1091the journal twice, and abort with an error if this is the case.
1092(Addresses IBM Bugzilla bug #1226)
1093
1094E2fsck will print an error if more than one of the -p/-a, -n or -y
1095options are specified.
1096
1097E2fsck will fix HTREE corruptions in preen mode, without stopping the
1098boot process. This is needed because the 2.4 ext2 filesystem
1099accidentally had the INDEX_FL backwards compatibility code removed.
1100
1101Mke2fs no longer creates filesystems with the dir_index flag set by
1102default; the user has to specifically request it.
1103
1104Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -04001105#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001106
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001107Created man page for the mk_cmds program (from the libss library).
1108
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001109Programmer's notes:
1110-------------------
1111
1112Fix various gcc -Wall nits.
1113
1114Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -05001115successfully under Solaris and Apple/Darwin.
1116
1117Fixed a Makefile dependency to allow building e2fsprogs using parallel
1118make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001119
1120Changes to create a subset distribution which consists only of the
1121et, ss, uuid, and blkid libraries. The configure script and top-level
1122makefile were changed to support working with a subset distribution.
1123
Theodore Ts'oba142c12003-04-16 00:59:59 -04001124Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1125actually used, and might people who are looking for
1126EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1127
Theodore Ts'o508d7f32003-03-16 20:41:04 -05001128Updated debian files to fix a number of Lintian warnings.
1129
1130Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001131
Theodore Ts'o71df0dc2003-04-21 16:17:09 -04001132Removed unnecessary libraries from being linked into the fsck, lsattr,
1133chattr, and blkid executables.
1134
Theodore Ts'o38513012002-11-09 15:00:56 -05001135E2fsprogs 1.32 (Nomvember 9, 2002)
1136==================================
1137
1138Fixed a bug in the Unix I/O routines which caused needless writebacks
1139of clean blocks from the unix_io cache (they were erroneously marked
1140as being dirty, so they were getting written back to disk before
1141getting evicted from the disk cache). This was harmless, but it
1142significantly slowed down e2fsck.
1143
1144Made some other minor optimizations to the Unix I/O routines to save a
1145small amount of CPU time.
1146
1147Updated internationalization files.
1148
Theodore Ts'o3809bf12003-03-07 01:09:57 -05001149
Theodore Ts'oae65b292002-11-08 20:08:48 -05001150E2fsprogs 1.31 (Nomvember 8, 2002)
1151==================================
1152
1153Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1154compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1155handling for child process that die unexpectly. Add a hack to force
1156mkfs to create filesystems that won't cause problems with hardware
1157that has 2k or 4k minimum blocksize requirements. Read from child
1158processes in non-blocking mode, so that the GUI continues to update.
1159
1160Fix e2fsck so that it returns the appropriate exit code when the root
1161filesystem has been changed, so that system's rc scripts will be told that
1162the system needs to be rebooted.
1163
1164Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1165was set, some of the descriptor blocks that should have been written
1166out were getting skipped.
1167
1168Changed e2fsck to force out changes to the backup copies of the
1169superblock and block group descriptors when important changes are made
1170to those data structures.
1171
1172Fix a bug where e2fsck could erroneously mark a filesystem as being
1173clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1174introduced in e2fsprogs 1.28.)
1175
1176If journal debuging is enabled using --enable-jbd-debug, the debugging
1177level is now set via the E2FSCK_JBD_DEBUG environment variable.
1178
1179If byteswapping support is disabled using configure --disable-swapfs,
1180skip the tests which depend on byte-swapping, so that "make check"
1181won't bomb out.
1182
1183Lshattr will now display the indexed directory flag. Also, some of
1184the more esoteric compression flags are supressed unless compression
1185support has been enabled.
1186
1187Update man pages.
1188
1189
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001190E2fsprogs 1.30 (October 31, 2002)
1191=================================
1192
1193When resizing a filesystem, and inodes need to moved, resize2fs will
1194update the inode's ctime field, and the mtime field of the containing
1195directories, so that incremental backups using dump/restore will work
1196correctly.
1197
1198In order to avoid spurious errors, e2fsck wil check the last
1199superblock write time to determine whether or not it can safely use
1200the LOW_DTIME checks to determine if there are inodes on the orphan
1201inode linked list that had somehow gotten disconnected. (Addresses
1202Sourceforge bug #620980)
1203
1204Partition in /proc/partitions that being with the string "lvm" are
1205considered real partitions even if they do not end with a number.
1206
1207Fixed a bug in the the uuid generation function, where if /dev/urandom
1208is not present, but /dev/random is, and there isn't sufficient
1209entropy, the get_random_byte function could spin a loop forever.
1210
1211E2fsck, mke2fs, etc. will now reliably notice when image files are
1212mounted using the loopback interface. (Addresses Sourceforge bug
1213#619119)
1214
1215When flushing buffers (as is done by badblocks, for example) check to
1216see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1217FDFLUSH ioctl which causes the MD device driver which causes confusing
1218syslog messages about obselete ioctl messages. (Addresses Sourceforge
1219bug #545832).
1220
1221Debugfs's write command now checks to see if the destination filename
1222exists before creating it. (Addresses Sourceforge bug #478195.)
1223
1224When installing man pages, search for compressed man pages using all
1225commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1226
1227Fixed a bug in fsck where multiple filesystems specified on the
1228command were not being checked in parallel due to a logic bug
1229introduced to support the FSCK_MAX_INST environment variable.
1230
1231We have added a new superblock field, s_mkfs_time, which indicates
1232when a filesystem was created. It is set via mke2fs, and printed out
1233by dumpe2fs, but is not actually touched by the kernel.
1234
1235Dumpe2fs has been made more robust by not aborting if there is an
1236error reading the block/inode bitmaps; instead it will still print out
1237the location of the block/inode bitmaps and inode table.
1238
1239Add support for the an alternative block group descriptor layout which
1240allows for on-line resizing without needing to prepare the filesystem
1241in advance. (This is the incomat feature flag meta_bg.)
1242
1243Add support for storing default mount options in the superblock, so
1244that the filesystem can be mounted with specific mount options without
1245needing to specify them on the mount command line or in the /etc/fstab
1246file.
1247
1248Add support for a new inode flag, which is to be used for indicating
1249the top of directory hierarchies for the Orlov block allocator.
1250
1251Fix e2fsck so that if it creates the lost+found directory, it does so
1252with the more apporpriate permissions of 0700. Also change
1253mklost+found so that it also creates the directory 0700.
1254
1255Fixed format bug in e2fsck if NLS is in use.
1256
1257Add a German translation for e2fsprogs's NLS support.
1258
1259Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
1260the beginning of the inode table. This won't matter much, since if
1261there is a bad block at the beginning of the inode table, the root
1262directory won't be available. But at least e2fsck won't crash in this
1263case.
1264
1265Fixed endian problems in the htree code for e2fsck and debugfs.
1266
1267When byte-swapping a filesystem on a PPC architecture, byte-swap the
1268bitmaps since the historical big-endian ext2 variant had byte-swapped
1269bitmaps, and the ext2fs library assumes this. This fixes the
1270regression test suite on PPC machines.
1271
1272Fix e2image so that it handles a bad block in the inode table
1273appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -04001274
1275E2fsck now uses a more sophisticated algorithm to salvage corrupted
1276directories that recovers more information in the corrupted directory
1277block.
1278
1279E2fsck now performs additional consistency checks on indexed (HTREE)
1280directories.
1281
1282Fix bug where efsck might get confused about whether a completely
1283empty directory block is an empty leaf block or an interior htree
1284node. This could cause e2fsck to get confused into think that a valid
1285indexed directory was corrupted.
1286
1287E2fsck no longer creates an empty directory entry at the end of a
1288directory block when optimizing a directory. This would cause some
1289earlier versions of the dxdir kernel code to corrupt the directory
1290when attempting to split a node containing an empty directory entry.
1291
1292E2fsck could sometimes in rare circumstances leave the indexed flag
1293set after a small directory was optimized by compressing it instead of
1294indexing it. (This should never happen in real life, since
1295directories that small wouldn't have been indexed, but better safe
1296than sorry.)
1297
1298E2fsck now only updates the master superblock in all cases. This
1299slightly shortens its run time.
1300
1301Ext2ed can deal with directory entries of length 0; previously it
1302would get stuck in an infinite loop.
1303
1304Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
1305specifiers. (Sourceforge patch #613447)
1306
1307Badblocks will now work correctly on read-only devices such as
1308CD-ROM's. (Sourceforge patch #600451)
1309
Theodore Ts'o5d823a42002-11-01 02:13:53 -05001310Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -04001313E2fsprogs 1.29 (September 24, 2002)
1314===================================
1315
1316Fixed a bug in e2fsck which could corrupt a directory when optimizing
1317it (via the -D option) or rebuiliding the hash tree index with a 1 in
1318512 probability, due to a fence post error.
1319
1320Fixed a bug in the LVM support code which caused LABEL='xxx' not to
1321work correctly.
1322
1323Mke2fs now enables the directory indexing flag by default. (Since
1324this is a compatible feature flag, it's safe to do so.)
1325
1326Tune2fs will support setting the directory indexing feature flag. It
1327will automatically set up the default hash algorithm and hash seed
1328fields in the superblock.
1329
1330If the bone-headed user enters the root filesystem twice in
1331/etc/fstab, the -R option which skips the root filesystem will skip
1332all of them. (Addresses Debian bug #159423). Note! This is not a
1333precedent for dealing intelligently with any other kind of doubled
1334entry in /etc/fstab!
1335
1336
1337Programmer's notes:
1338-------------------
1339
1340Removed perror declaration in lib/et/internal.h. All modern systems
1341can be expected to define perror() these days. Besides, the lib/et
1342code wasn't using perror at all anyway. :-)

Theodore Ts'ob7bad612002-08-31 03:00:33 -04001345E2fsprogs 1.28 (August 31, 2002)
1346================================
1347
1348Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
1349for setting the htree flag is not included yet, although it can be
1350manually turned on via the debugfs program.
1351
1352Clarified e2fsck error message which is printed when it cannot find
1353sufficient contiguous block when relcating filesystem metadata.
1354
1355Added support for building an EVMS plugin module for ext2/3. This
1356module is substantially the same as the EVMS module shipping with EVMS
13571.1, with one or two bugfixes. E2fsprogs can also build this plugin
1358for use with EVMS 1.0 (which did not include the ext2 plugin module),
1359if the configure --enable-old-evms flag is given.
1360
1361Fsck will search through EVMS volumes when trying to resolve
1362filesystem specifications such as LABEL=xxx or UUID=xxx.
1363
1364Added a new utility program, /sbin/findfs, which will return
1365filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
1366the device name.
1367
1368Update and clarified various man pages. (addresses Debian Bug #145044,
1369#146437, #131350, #151990, #144621, #141938)
1370
1371If there are no filesystems specified on fsck's command line, fsck now
1372treat that as if the -As options were given. Previously it would
1373simply do nothing. (Addresses Debian Bug #153102)
1374
1375Mke2fs no longer treats a failure to be able to clear the MD signature
1376at the end of the filesystem as a fatal error. (Addresses Debian Bug
1377#155007)
1378
1379The e2p library functions (which are used by lsattr and chattr) now
1380double check to make sure the file is a regular file or directory
1381before attempting to use the ext2 ioctls. Some device drivers
1382unfortunately respond to the ext2 ioctl's with unknown behaviour.
1383(Addresses Debian Bug #152029).
1384
1385The extended attribute handling has been updated to correspond with
1386the latest V2 bestbits ACL code.
1387
1388Fixed bug in e2fsck which caused it to not clear the dtime field when
1389processing truncated inodes on the orphan list. This could cause data
1390loss(!) if a filesystem is rebooted before a truncate has been
1391committed.
1392
1393E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
1394algorithms. This makes e2fsck much faster in the case of severely
1395corrupted filesystems where a large number of blocks are claimed by a
1396large number of inodes. (Thanks to the 2.5 IDE device driver for
1397inspiring this work.)
1398
1399Resize2fs has been significantly sped up when shrinking and expanding
1400a filesystem by a very small number of blocks (for example, when EVMS
1401is converting a partition to be an EVMS legacy volume).
1402
1403Added a new option to e2fsck, -D, which will optimize or compress all
1404of the directories in the filesystem.
1405
1406E2fsck now catches SIGINT and SIGTERM to make sure it will can
1407properly clean up and only exit at safe points. Fsck will pass
1408SIGINT/SIGTERM to its child processes, and wait until they have all
1409exited before it exits.
1410
1411The uuid parsing code in the uuid library now properly complains when
1412an illegally formated uuid is presented to it. (Addresses Debian bug
1413#152891)
1414
1415Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
1416and 2.4.17, since the workaround can cause problems when using a 2.4
1417kernel with an old version of glibc built with the 2.2 headers.
1418
1419Fixed a bug in mke2fs where it wasn't properly clearing the initial
1420superblock used by other filesystems. (Addresses Debian bug #147256.)
1421
1422Added support for the synchronous directory feature written by Andrew
1423Morton.
1424
1425The debugfs program can delete directories using the rmdir command.
1426
1427Add support for 8k and 16k filesystems (for systems with page sizes
1428that are greater or equal to 8k or 16k, respectively). Note that
1429these filesystems can not be mounted on x86 systems, or other systems
1430with only 4k page sizes, due to limitations in the current Linux VM
1431code.
1432
1433Resize2fs requires that the filesystem state be valid and have no
1434errors; otherwise, e2fsck -f must be run first. (Previously it simply
1435required that the last fsck time be greater than the last mount time.)
1436
1437Configure now defaults the man pages directory to /usr/share/man on
1438Linux systems.
1439
1440E2fsck now offers to truncate inodes which contain too many blocks (so
1441that i_blocks would overflow. Also fixed handling of large sparse
1442files.
1443
1444E2fsck now more completely checks for symlink validity, including
1445requiring NULL termination and length checks.
1446
1447E2fsck will offer to try forcing a disk write to remap a bad block
1448after finding a read error when reading a filesystem metadata block.
1449
1450Fixed a bug in debugfs which caused the -b and -s options to crash
1451debugfs, as well as breaking the testb, setb, and clearb functions.
1452
1453Added a bmap command to debugfs which calculates the logical to
1454physical block mapping for a particular inode.
1455
1456Fixed a bug in code which checked to see if a device was mounted which
1457sometimes (rarely) failed in the case of a plain file.
1458
1459Fixed a bug in resize2fs where when it reported an error, it would
1460print a message erroneously indicating that the filesystem had been
1461resized before it aborted.
1462
1463When resizing a plain file which is smaller than the requested size,
1464resize2fs will attempt to extended the file so that programs like
1465e2fsck will not complain that the file is too small.
1466
1467Resize2fs will print the actual new size of the filesystem when it is
1468finished resizing.
1469
1470Fixed a bug in debugfs where "ls -l" would report incorrectl file type
1471information on big-endian systems.
1472
1473
1474Programmer's notes:
1475-------------------
1476
1477Fixed collisions with C++ reserved words.
1478
1479Added portability fixes for building e2fsprogs on the HURD and AIX.
1480
1481Added the ext2ed program for creation of test cases. (ext2ed has many
1482limitations and bugs which make it unsuitable for production use.)
1483
1484The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
1485flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
1486name_len field is byte swampped on big-endian machines, since in the
1487V2 structure, name_len is a char field which is doesn't need to be
1488byte swapped --- except if an old-style kernel had byte-swapped the
1489name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -05001492E2fsprogs 1.27 (March 8, 2002)
1493==============================
1494
1495The warning messages for mke2fs now go to standard error.
1496
1497Fixed to make sure "make check" runs all of the test programs with
1498LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
1499
1500The mke2fs program checks the boot sector for the BSD disk label, and
1501avoids erasing it if it is there.
1502
1503Fixed a bug in e2fsck which caused it to core dump if the journal
1504inode was missing when it was supposed to be there.
1505
1506E2fsck now prints ranges in pass 5 when printing deltas for the block
1507and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001508
1509Debugfs's "ls -l" command now will print out the file type information
1510in the directory entry.
1511
1512Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
1513mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
1514
1515Debugfs can now examine the experimental directory indexing
1516information.
1517
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001518Fixed bug in debugfs which caused it to core dump if modify_inode is
1519called without an open filesystem.
1520
1521The debugfs lsdel command now runs its output through a pager first.
1522
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001523When installing manual pages, remove the compressed manual pages first.
1524
1525Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
1526
1527Fix the 2.4 resource limitation workaround introduced in 1.26 which
1528actually broke things on mips32, sparc32, and Alpha platforms.
1529
Theodore Ts'oa471ac52002-03-05 03:37:06 -05001530Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
1531(which is required by the newer libintl libraries).
1532
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001533Programmer's notes:
1534-------------------
1535
Theodore Ts'oa8e77242002-03-08 03:12:14 -05001536Fixed various gcc -Wall complaints.
1537
Theodore Ts'oafa14ba2002-03-05 03:31:06 -05001538Fixed a few memory leaks in the e2fsck journaling code, and in the
1539ismounted code checking for a swap device.
1540
1541Add new inode I/O abstraction interface which exports an inode as
1542an I/O object.
1543
1544Exported ext2_file_flush as a public interface.
1545
1546In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
1547
1548Lots of small random portability fixes to make e2fsprogs build under
1549AIX --- even without the 5L compatibility toolkit, and even using the
1550uber-crippled AIX native C compiler.
1551

Theodore Ts'o06987392002-02-03 01:36:54 -05001553E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001554=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001555
Theodore Ts'o446314f2001-12-24 15:22:27 -05001556Dumpe2fs will keep going now if the bad block inode can't be read.
1557(Previously it stopped with a fatal error.)
1558
1559E2fsck will now give an opportunity to run the journal even if the
1560recovery flag is not set. This is the default behaviour if e2fsck is
1561using a backup superblock, since the needs_recovery flag will never be
1562set in the backup superblock copies.
1563
1564E2fsck now automatically finds the backup superblock/group descriptors
1565even when the primary superblock is completely destroyed for 2k and 4k
1566filesystems. (Previously it just guessed/assumed that we were dealing
1567with a 1k filesystem in that case, and users had to manually specify
1568the backup superblock number.)
1569
1570Fixed a bug in e2fsck where it dereferences a null pointer when there
1571is a problem opening a filesystem in preen mode.
1572
1573E2fsck now handles external journals correctly; previously it trashed
1574the external journal device if the journal needed to be replayed.
1575
1576Work around ulimit incompatibility problem caused by recent 2.4
1577kernels; the unix IO module will automatically try to set any resource
1578limits to be infinite on startup.
1579
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001580Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1581bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001582 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001583
1584E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1585clearing the new V2 fields if they do not make sense or if the ext3
1586superblock is version 1 superblock.
1587
1588E2fsck will automatically relocate the ext3 journal from a visible
1589file (i.e., /.journal) to an hidden inode if the filesystem has been
1590opened read/write. This allows the users to add a journal while the
1591filesystem is mounted, but the next time the system is rebooted, the
1592journal file will disappear. This avoids problems with backups,
1593stupid operators with superuser bits, etc.
1594
1595Fix a bug in fsck where it would not support a filesystem type of
1596"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1597
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001598Fsck now supports fstab entries of the form "ext3,ext2". It will also
1599automatically identify reiserfs filesystems.
1600
1601The number of processes spawned by fsck can now be limited using the
1602FSCK_MAX_INST environment variable.
1603
Theodore Ts'o446314f2001-12-24 15:22:27 -05001604Fsck now searchs the LVM proc hierarchy to find logical volumes which
1605should be searched for UUID and label information.
1606
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001607Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1608limit if at all possible, when opening a block device. (The filesize
1609limit shouldn't be applied against writes to a block device.)
1610
Theodore Ts'o446314f2001-12-24 15:22:27 -05001611In mke2fs and e2fsck, specifying the -c option twice will now do
1612a read/write test on the disk. Update the man pages to encourage
1613using the -c option, and to discouraging running badblocks separately,
1614since users tend to forget to set the blocksize when running
1615badblocks.
1616
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001617Mke2fs now automatically clears the immutable attribute on a
1618pre-existing .journal file left over from a previous failed attempt to
1619add a journal to an alreadyy-mounted filesystem.
1620
1621Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1622operation failed.
1623
Theodore Ts'o446314f2001-12-24 15:22:27 -05001624Mke2fs now creates the lost+found directory with permissions of 0700,
1625so that files that had previously lived in protected directory are
1626safe if they get dropped in lost+found and the system administrator
1627doesn't deal with immediately. (Addresses Debian #bug 118443)
1628
1629Mke2fs and e2fsck (and all programs that use the
1630ext2fs_check_if_mounted function) will now properly identify that a
1631device is mounted, even in cases where devfs has confused things with
1632multiple devices names with the same identity, or if a dim-witted
1633system administrator has done something stupid like creating device
1634file aliases in their home directory. Also now checks for swap devices
1635by using /proc/swaps. (Addresses Debian bug #106622)
1636
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001637Added a new option (-T) to tune2fs which sets the time a filesystem
1638was last checked.
1639
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001640Speed up e2image when creating sparse raw image files by optimizing
1641away excess lseek() system calls.
1642
1643Fix support of large (> 2GB) files when used as a filesystem in
1644mke2fs, tune2fs, debugfs, and findsuper.
1645
1646Debugfs's stat and icheck commands now properly deals with large (>
16472GB) files.
1648
1649Debugfs's set_super_value command now prints out the list of valid
1650superblock fields which can be set using the command.
1651
Theodore Ts'o446314f2001-12-24 15:22:27 -05001652Debugfs's rm and kill_file command now updates the superblock free block
1653and inode counts, thus keeping the filesystem consistent.
1654
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001655Debugfs's lsdel command now takes an optional argument which allows
1656the user to only see the most recently deleted files.
1657
1658A new command (undel) was added to debugfs which automates
1659undeleting a deleted inode and linking it back to a directory.
1660
1661Debugfs's ls command now takes a new option, -d, which lists
1662deleted directory entries.
1663
1664Debugfs's testb, freeb, setb, and find_free_block commands now take an
1665optional count argument.
1666
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001667Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1668be used to signal that a particular inode should not be eligible for
1669tail-merging --- this is needed for programs like LILO.
1670
1671The findsuper (an unreleased, uninstalled utility program) has been
1672improved to add extra validity checks and to add a progress meter.
1673(It is still an unsupported program; the officially supported way to
1674recover from a trashed partition table is to use gpart; findsuper is
1675for wizards only. :-)
1676
1677Debugfs was fixed to compile with "configure --disable-swapfs".
1678
Theodore Ts'o446314f2001-12-24 15:22:27 -05001679Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001680
1681Added new translation file for Turkish.
1682
Theodore Ts'o446314f2001-12-24 15:22:27 -05001683Programmer's notes:
1684-------------------
1685
1686Fix general gcc -Wall complaints.
1687
1688E2fsprogs (mostly) works with the dietlibc.
1689
1690The programming texinfo file has been expanded to include description
1691of additional libext2fs functions. (Still not compeltely done, but a
1692lot of the more important functions have been documented.)
1693
1694Added a umask structure to struct_ext2_filsys, which currently only
1695modifies the behaviour of ext2fs_mkdir(), but if we add any file
1696creation functions to libext2fs, we should also make sure they respect
1697the umask setting.
1698
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001699The build-rpm script was fixed to be a bit more safe.
1700
1701The tests' Makefile now has a way of automating test case creation
1702for e2fsck, using "make testnew".
1703
1704Created a new function, ext2fs_dir_iterate2 which passes more
1705information to the callback function (identical to the one used by
1706ext2fs_dblist_dir_iterate). The directory iterator functions take a
1707new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1708directory entries. If the directory entry is deleted, the callback
1709function will be called with the entry paraemter set to
1710DIRENT_DELETED_FILE.
1711
1712Added new functions, ext2fs_inode_alloc_stats and
1713ext2fs_block_alloc_stats, which takes updates block/inode allocation
1714statistics in the bitmaps, block group descriptors, and superblock
1715when inodes or blocks are allocated or deallocated.
1716

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04001718E2fsprogs 1.25 (September 20, 2001)
1719===================================
1720
1721This is primarily a bug-fix release; no new features were added, but
1722there are a number of embarassing bug fixes and cleanups applied.
1723
1724Fix a bug mke2fs which causes stack garbage to be written to disk when
1725zapping disk sectors. (This bug could cause mke2fs to core dump for
1726some kernels, I suspect with security enhancement patches.)
1727
1728Remove unneeded #include of <linux/config.h> which was breaking
1729building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1730
1731Updated tune2fs man page to reflect the fact that adding or removing a
1732journal doesn't require running e2fsck.
1733
1734Remove use of AC_REQUIRE from autoconf which had been used to prevent
1735AC_CANONICAL_HOST from being called twice; unfortunately this causes
1736recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1737used outside of autoconf macros. Fortunately, it doesn't seem to be
1738necessary any more, anyway.
1739
1740E2fsck will now not fall back to an alternate superblock if the user
1741specifies the superblock location explicitly on the command-line.
1742This allows easier recovery from a situation where the primary
1743superblock and block groups are slightly corrupted, but the backup
1744superblocks are completely broken.
1745
1746Fix problem which caused compile_et and mk_cmds to blow up if
1747e2fsprogs was in a directory with a pathname that contained spaces.
1748
1749We are now more paranoid about checking the entry in /etc/mtab to make
1750sure the filesystem is really mounted, since some broken distributions
1751(read: Slackware) don't initialize /etc/mtab before checking non-root
1752filesystems. (Slackware also doesn't check the root filesystem
1753separately, and reboot if the root filesystem had changes applied to
1754it, which is dangerous and broken, but there's nothing I can do about
1755that.)
1756
1757Make UUID library C++ friendly by adding appropriate extern "C"
1758declarations and using const in the function declarations.
1759
1760Fix up the com_err texinfo file so that it can product a valid info
1761file (previously, it could only be used to generate paper
1762documentation using texinfo.tex).
1763
1764
Theodore Ts'ofb707752001-09-04 15:00:37 -04001765E2fsprogs 1.24a (September 2, 2001)
1766===================================
1767
1768Fix brown-paper bug in mke2fs which caused it to segfault when
1769printing the version string.
1770
1771
Theodore Ts'o109624a2001-08-31 00:59:55 -04001772E2fsprogs 1.24 (August 30, 2001)
1773================================
1774
1775Revert the BLKGETSIZE64 support, since for some distributions, this
1776ioctl has been used by an unofficial kernel patch to update the last
1777sector on the disk, and this was causing disk corruption problems as a
1778result.
1779
1780Mke2fs is now more careful about zapping swap space signatures and
1781other filesystem/raid superblock magic values so that programs like
1782mount who try to use hueristics to determine the filesystem type of a
1783partition are less likely to be confused.
1784
1785E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1786regular file (since Andreas Dilger's on-line resizing tools will set
1787its mode bits).
1788
1789Fixed some minor texinfo, man pages nits for spelling errors,
1790texinfo warnings, etc. (Addresses Debian bug #110621.)
1791
1792E2fsprogs program no longer print the filesystem version number
1793(i.e. 0.5b), since it only confuses people and doesn't serve any real
1794purpose.
1795
1796E2fsck will once again compile under libc5, since it will supply its
1797own version of strnlen if necesssary.
1798
1799mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1800when specifying the external journal device. tune2fs will also search
1801devices looking for the externla journal debice when removing.
1802
1803E2fsprogs 1.23 (August 15, 2001)
1804================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001805
1806Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001807correctly handle a filesystem with EA's and check the EA blocks for
1808corruptions.
1809
Theodore Ts'od494bba2001-08-09 06:14:42 -04001810E2fsck's symlink sanity checking has been cleaned up. It now checks
1811the i_size value of fast symlinks, and checks for immutable flags
1812being set of symlinks, etc.
1813
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001814E2fsck now offers to clear inodes which are special files that have a
1815non-zero i_blocks or i_size field. (The i_size field check was in the
1816previous version of the code, but due to a bug it didn't offer to
1817clear the inode unless i_size and i_size_high were both non-zero.)
1818
Theodore Ts'od494bba2001-08-09 06:14:42 -04001819E2image can now create "raw" image files, which only contain the
1820filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1821debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001822
1823Add support for the 64-bit block device patches.
1824
1825Fixed bugs in creating external journals with a 1k blocksize.
1826
Theodore Ts'od494bba2001-08-09 06:14:42 -04001827Add initial support for external journals (so long as the external
1828journal only supports a single filesystem) in e2fsck.
1829
1830Remove requirement for needing to run fsck on a filesystem after
1831removing a journal (either internal or external).
1832
Theodore Ts'obf16d102001-07-27 22:20:06 -04001833The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001834
1835Speed up the check of an ext3 filesystems by avoiding a needless flush
1836of all of the superblock and block group descriptors.
1837
Theodore Ts'od494bba2001-08-09 06:14:42 -04001838Speed up creating an internal journal using tune2fs in the case where
1839the filesystem has a lot blocks already allocated.
1840
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001841Tune2fs has been fixed to make sure that only error messages go to
1842stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1843
Theodore Ts'od494bba2001-08-09 06:14:42 -04001844Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001845now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04001846
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001847Add support in fsck for the filesystem type "auto".
1848
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001849Fsck -A will not try to interpret device names for filesystems which
1850have a pass number is 0. (Addresses Debian bug #106696).
1851
1852Fsck prints a warning message if now valid filesystems are passed to
1853it. (Addresses Debian Bug #107458.)
1854
Theodore Ts'o9249d982001-07-20 18:14:10 -04001855E2fsck now gives an explicit warning if there filesystem still has
1856errors at the end of the run. (Addresses Debian bug #104502)
1857
Theodore Ts'od494bba2001-08-09 06:14:42 -04001858E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001859reflects an error. E2fsck will also not run the orphan list if the
1860filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04001861
1862E2fsck now prints the number of large files when given the -v option.
1863
1864Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001865
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001866Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04001867
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001868
Theodore Ts'o19d6b542001-06-23 00:13:09 -04001869E2fsprogs 1.22 (June 22, 2001)
1870==============================
1871
1872Fixed a bug in e2fsck's handling of orphan inodes which are special
1873files (i.e., block/character device files, named FIFO's, etc.).
1874
1875Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1876tune2fs to fail at adding a journal to a mounted filesystem.
1877
1878Fixed a few big-endian bugs in e2fsprogs
1879 * The directory block functions were accidentally reporting
1880 some directories as corrupted when they weren't.
1881 * If e2fsprogs is compiled --disable-swapfs, the C language
1882 equivalents weren't being included for big-endian platforms.
1883 (Fixes Debian bug #101686).
1884
1885Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1886
1887Programmer's notes:
1888-------------------
1889
1890Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1891ioctls, and allow them to be defined for non-i386 platforms.
1892
1893The uuid.h header file is now protected against multiple inclusions.
1894
1895E2fsprogs is now being developed using BitKeeper. Changed the test
1896scripts to deal with BK's stripping CR characgters from text files,
1897and changed the top-level Makefile.in to avoid including BitKeeper
1898files when generating the source tarball.
1899
1900
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001901E2fsprogs 1.21 (June 15, 2001)
1902==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00001903
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001904Added new configure flags which allow a subset e2fsprogs to be built;
1905this is most useful for boot floopies, since the resulting shared
1906libraries and programs are slimmed down by removing features that
1907aren't necessary for a boot floppy. The new flags that were added
1908are: --disable-swapfs, which removes support for byte swapping old
1909legacy PPC/68k filesystems, --disable-debugfs, which removes support
1910for debugfs from the libext2fs library, --disable-imager, which
1911removes support for the e2image program, and --disable-resizer, which
1912removes support for resize2fs.
1913
1914E2fsck now prints the number of mounts or days elapsed since the last
1915check when e2fsck is forced to check an otherwise clean filesystem.
1916
1917Tune2fs now prints an informative message about how often a filesystem
1918will be checked when adding a journal to the filesystem, to remind the
1919user that he/she may want to adjust those parameters using tune2fs
1920-c/-i.
1921
1922Worked around hurd brain-damage which causes e2fsck to sometimes
1923believe a filesystem is the root filesystem based on device numbers
1924(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1925violation).
1926
1927Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1928erroneous error with the -F option was specified.
1929
1930Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001931ext3 0.7a.
1932
Theodore Ts'o767de092001-06-02 01:20:18 +00001933Fixed two bugs in e2fsck's handling of dup block handling, dealing
1934with relatively uncommon edge cases: a directory with an indirect
1935block which is claimed by another file, and when the last inode in the
1936filesystem has blocks claimed by another file.
1937
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00001938E2fsck now checks to see if the i_size field of a fast symlink is too
1939big, and offers to clear the symlink if so.
1940
1941E2fsck now checks to see if i_size_high of special files is non-zero,
1942and offers to clear i_size_high.
1943
Theodore Ts'o767de092001-06-02 01:20:18 +00001944Fix e2fsck's handling of incompatible journal flags so that the user
1945has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00001946entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00001947
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001948Fixed a bug in fsck which could cause it to core dump if a mix of
1949standard and non-standard device names are used in /etc/fstab.
1950(Debian bug #100559)
1951
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001952Fixed a bug in debugfs which caused read errors when copying a file to
1953not be noticed.
1954
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001955The debugfs set_super_value command can now modify the s_lastcheck field.
1956
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001957Fixed a bug in lsattr and chattr which was accidentally introduced in
19581.20 to support > 2GB files; both lsattr and chattr wasn't reading
1959directories correctly because the change modified the layout of struct
1960dirent to be incompatible with the libe2p shared library.
1961
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001962Cleaned up the mke2fs manual page and included a discussion about why
1963it's good to periodically check the filesystem even when journaling is
1964enabled.
1965
Theodore Ts'o767de092001-06-02 01:20:18 +00001966Programmer's notes:
1967-------------------
1968
1969Fix general gcc -Wall complaints.
1970
1971The types needed by the ext2 header files are now provided by
1972lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1973
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001974Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001975in ext2_types.h. Also, if linux/types.h has already been defined,
1976don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001977
Theodore Ts'o767de092001-06-02 01:20:18 +00001978Fixed make depend script so that it automatically corrects the
1979pathname cleanups performed by make -M, so I don't have to fix them up
1980by hand.
1981
1982Fixed the d_loaddump test case to be more robust, and not depend on
1983bash'isms.
1984
1985Removed debugfs's dependence on pread(), which was accidentally
1986intrudced in e2fsprogs 1.20
1987
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001988Fixed a performance bug in the libext2fs's icount routine; the size
1989estimate of the icount array was incorrectly being calculated.
1990
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001991Removed use of the badblocks compatibility functions in the e2fsprogs
1992programs.
1993
1994Added paranoia code which protects against strange cases where /etc
1995isn't on the root filesystem, or if /etc/mtab doesn't exist.
1996
1997The header file ext2_types.h is now installed.
1998
1999Autoconf is used to determine when we are on big-endian machines,
2000instead of doing run-time tests, to save a few bytes of code.
2001
2002The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
2003functions are no longer inline functions, which saves space and
2004doesn't really cost any real performance.
2005
2006The ext2fs library no longer depends on the e2p library. (What need
2007there was of it --- namely, fsetflags, was coded in-line).
2008
2009Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
2010when the user is stupid and tries compiling the package using "make
2011install" as root.
2012
2013Miscellaneous code cleanups:

2015 their dependencies would be properly calculated.
2016 * Removed redundant code
2017 * Fixed comments in code
2018 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002021E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002022=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00002023
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002024Add support for replaying the ext3 journal purely in user mode,
2025including handling the orphaned inode list. Used code contributed by
2026Andreas Dilger, with bug fixes and the orphaned inode handling done
2027by Theodore Ts'o.
2028
2029The mke2fs and tune2fs programs can create or modify a filesystem to
2030include an ext3 journal. Tune2fs also can be used to remove an ext3
2031journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002032
2033E2fsck will now check for the existence of a linked list of orphan
2034inodes in the superblock, and clear those inodes before starting the
2035rest of the filesystem check (but after the journal playback).
2036
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002037E2fsck now validates the file descriptor passed to the -C option,
2038which saves against the completion bar getting written to an
2039unexpected location, such as the disk being checked. (Debian
2040bug/wishlist #55220)
2041
2042E2fsck will now bump the filesystem revision number from zero to one
2043if any of the compatibility bits are set.
2044
2045Fixed a bug where a badly corrupted directory on a big endian system
2046could cause e2fsck to die with a bus error. The
2047ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
2048the ext2 library now does alignment sanity checks on the rec_len field
2049of the directory entry before using it.
2050
2051The ext2 library has been enhanced to make tune2fs safe to run on
2052mounted filesystems. (Users could usually get away with using tune2fs
2053on mounted filesystems before, but with the advent of ext3 and
2054journaling, it became important to make tune2fs was *really* safe for
2055use even when the filesystem being modified is mounted.) E2label is
2056now implemented by tune2fs using an argv[0] dispatch, so that e2label
2057is also now safe for use on mounted filesystems.
2058
2059Added a new program, e2image, which creates a backup of critical ext2
2060filesystem data structures. The generated image file can be examined
2061using dumpe2fs and debugfs. In the future, e2fsck will be able to use
2062the image file to help recover very badly damaged filesystems.
2063
2064Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
2065no longer cause e2fsck to bomb out. Also treat files > 2GB as being
2066large file when deciding whether or not the filesystem has large files.
2067
2068Fixed lsattr and chattr so that they work correctly on large files.
2069(Fixes Debian bug #72690.)
2070
2071Removed limitation in get_device_size() which imposed a one terrabyte
2072filesystem limitation. (Most 2.2 kernels still have a signed int
2073problem which cause 1 TB block device limitation. Fortunately, the
2074kernel patches to fix this are much easier than fixing the 2TB
2075limitation in the kernel. :-)
2076
2077A max_mount_count of zero is now treated as if no mount count were
2078set. (Previously, no mount count was indicated by using -1, and a
2079mount count of zero caused e2fsck to always be run.)
2080
Theodore Ts'o77648562001-05-14 13:04:44 +00002081Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002082
2083Mke2fs now adds some randomness in s_max_mount_count so that multiple
2084filesystems won't be all checked at the same time under normal
2085operations.
2086
Theodore Ts'o5570a652000-08-21 01:23:39 +00002087Fixed bug in the progress bar printing code which could cause e2fsck
2088to core dump on an illegal filesystem.
2089
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002090Fixed bug in fsck which could allow more than one instance of e2fsck
2091to be printing a progress bar. (Debian bug #65267)
2092
Theodore Ts'o5570a652000-08-21 01:23:39 +00002093Fsck using a UUID or a LABEL specifier will work even if devfs is
2094compiled into the kernel and not mounted. If the pathnames in
2095/proc/partitions are incorrect, fsck will search /dev for the correct
2096device (using the new ext2fs_find_block_device library function).
2097Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002098found when they are in use. Support has also been added to support
2099additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2100
2101Fixed a bug in fsck which caused it not deal properly with 16
2102byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002103
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00002104Fsck's -t option has been made a lot more flexible. The semantics for
2105what happens if a comma-separated list to fsck has been regularized,
2106and it is now possible to filter what filesystems will get checked
2107based what is in the filesystem's fstab entry's option field. (Debian
2108bug #89483.)
2109
Theodore Ts'o5570a652000-08-21 01:23:39 +00002110The dumpe2fs program can now print out the group description
2111information in hex, and also prints the location of the superblock and
2112block group descriptor for those block groups that have them.
2113
2114Mke2fs now clears the ext2 superblock before it starts creating a
2115filesystem, so that the superblock magic number is only written if the
2116filesystem creation process successfully completes.
2117
2118The debugfs program's stat command now pretty-prints the blocks used
2119by an inode so that it's more compact and informative.
2120
2121The debugfs stats command now uses the same libe2p code (which is used
2122by dumpe2fs) to print the superblock header information. This is more
2123complete, and it avoids a bit of code duplication.
2124
2125Added a new debugfs command, set_super_value (ssv) which allows the
2126user to set arbitrary superblock fields.
2127
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002128Debugfs was extended to support inode numbers in hex (by prefixing
2129them with 0x), and so that modify_inode can set the inode generation
2130number. Also, there is now a new function command called logdump
2131which will dump an ext3 journal.
2132
2133Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2134debugfs.
2135
2136Debugfs's dump command now stops immediately upon reporting a disk
2137read error. (Fixed a bug in ext2fs_file_read library routine which
2138caused debugfs not to stop.) (Debian bug #79163)
2139
2140On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2141checked before /etc/mtab is used, since /proc/mounts is more likely to
2142be accurate.
2143
2144Added portability fixes for Solaris and Linux/ia64.
2145
2146Various manual pages were clarified and cleaned up. (Fixed debian
2147bugs #63442, #67446, and #87216)
2148
Theodore Ts'o5570a652000-08-21 01:23:39 +00002149
2150Programmer's notes:
2151-------------------
2152
2153The e2fsck message printer now supports %Iu and %Ig, which will print
2154out the inode's user and group owners, respectively.
2155
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002156E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2157that no longer dependent on the system having the correct version of
2158the kernel header files.
2159
Theodore Ts'o5570a652000-08-21 01:23:39 +00002160Added a new function to libext2, ext2fs_find_block_device(), which
2161searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2162device given its device number.
2163
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002164Added a new function to libext2, ext2fs_sync_device, which centralizes
2165all of the places which might try to use the BLKFLSBUF or FDFLUSH
2166ioctls (and usually failing to define them since the system header
2167files don't usually do this for us, and we're trying to avoid usage of
2168kernel include files now).
2169
Theodore Ts'o5570a652000-08-21 01:23:39 +00002170Added new utility programs in tests/progs: random_exercise and
2171hold_inode. They aren't built by default; they're useful for
2172exercising ext3 filesystem code.
2173
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002174Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2175the filesystem close functions to only update the superblock, and to
2176not touch the block group descriptors. Needed by tune2fs when
2177modifying a mounted filesystem.
2178
2179Got rid of struct ext2fs_sb and replaced it with the standard struct
2180ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2181source (but not binary) compatibility of some users of the ext2
2182library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00002183replace of struct ext2fs_sb with struct ext2_super_block, and include
2184the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002185
2186The ino_t type has been renamed ext2_ino_t to protect applications
2187that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2188inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2189unexpected ABI change.
2190
2191The Makefiles have been reworked so that "make check" can be run from
2192the top-level Makefile.
2193
2194Fix general gcc -Wall complaints and removed dead code.
2195
2196Remove use of NOARGS, because we assume everyone does ANSI C these
2197days.
2198
2199Added build-rpm script from sct.
2200
2201New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2202to support e2image.
2203
2204New function ext2fs_flush_icache which must be called if the
2205application program modifies the inode table blocks without going
2206through ext2fs_write_inode() interface.
2207
2208New ext2fs_check_mount_point() function, which will return the mount
2209point of a device if mounted.
2210
2211The io_channel abstraction now has an optional interface,
2212io_channel_write_range, which allows specific byte ranges to be
2213written.
2214
2215The unix_io IO channel now supports write-through caching, so that
2216journal creation is more efficient.
2217
2218Added x86 assembly language routines to support byte swapping, to
2219reduce executable size.
2220
2221Fixed bug in the utility program subst so that it's possible to
2222replace a substitution variable with a zero-length string.
2223
2224Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2225slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00002226
Theodore Ts'ob777e262000-07-27 01:39:23 +00002227E2fsprogs 1.19 (July 13, 2000)
2228==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00002229
2230Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00002231be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00002232
2233Add experimental support needed for the ext2 compression patches.
2234This requires compiling e2fsprogs with the --enable-compression flag
2235to the configure script.
2236
2237Added ext3 journalling support. E2fsck will run the journal (if
2238necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2239installed as a symlink to e2fsck. Fsck has been taught about ext3,
2240and treats it the same as ext2 in terms of the progress bar logic.
2241Dumpe2fs will display the superblock journaling information if the
2242filesystem has a journal. The ext2 library will now permit opening an
2243ext3 filesystem with the recovery flag set. This is necessary for
2244on-line dump's to work correctly, but there may be issues with this
2245working well since ext3 is much less agressive about syncing blocks to
2246the filesystem, since they're safe on the journal.
2247
2248Tune2fs and e2fsck have been changed to allow the mount_count check to
2249be disabled by setting max_mount_count to -1. (This was already
2250supported by the kernel.)
2251
2252Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
2253are used for ext3 as well.
2254
2255Added internationalization support for e2fsprogs; must be enabled
2256by passing --enable-nls to configure.
2257
2258Always use the provided ext2fs header files to insulate ourselves from
2259kernel version changes. Which include files are used by e2fsprogs
2260have also been cleaned up to improve portability.
2261
2262Limit the number of times that e2fsck updates the progress bar so that
2263people who are booting using a 9600 baud console don't get swampped by
2264too many updates.
2265
2266Improved the loop detection algorithm in e2sck's pass #3 so that it is
2267much, much faster for large filesystems with a large number of
2268directories.
2269
2270The memory footprint for e2fsck is now slightly smaller than before.
2271
2272E2fsck now checks if special devices have a non-zero size, and offers
2273to clear the size field if it finds such an inode.
2274
2275E2fsck now checks if special devices have the append-only flag set,
2276and offers to clear the inode.
2277
2278E2fsck now properly handles some "should never fail" cases during a
2279bitmap copy in pass5.
2280
2281E2fsck now properly prints control characters in filenames as ^A .. ^Z.
2282
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002283E2fsck now calculates the correct location of the backup superblock in
2284the case of filesystem blocksizes > 1k.
2285
2286Fixed a bug in e2fsck's calculation of the number of inodes_per_block
2287which normally didn't cause problems under most filesystem parameters,
2288but could cause a valid superblock to be rejected in extreme cases.
2289Other checks for validating superblock values were made more
2290stringent.
2291
Theodore Ts'oab146762000-07-07 04:37:35 +00002292Added non-destructive write testing to the badblocks program, courtesy
2293of David Beattie. The badblocks also now has an option to input the
2294current set of bad blocks, so that known bad blocks are skipped to
2295speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00002296feature which causes badblocks to run until it has completed some
2297number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00002298
2299Badblocks now checks to see if the device is mounted and refuses to do
2300the tests involving writing to the device if it is mounted. Also,
2301badblocks now allows the number of blocks to be checked to be
2302defaulted to the size of the partition.
2303
2304Fixed a bug in fsck which didn't allow non-root users to be able to
2305check filesystems if there were any LABEL= or UUID= entries in
2306/etc/fstab.
2307
2308The Hurd doesn't support the filetype filesystem feature. The mke2fs
2309program now makes sure that for the Hurd, the filestype feature is
2310turned off. E2fsck will check to see if the filetype feature is
2311turned on for Hurd filesystems, and offer to turn off the feature.
2312
2313Mke2fs now has a safety check to make sure the number of blocks do not
2314exceed 32 bits even on a 64 bit platform.
2315
2316Really fixed a bug in fsck to allow "fsck -As" to run interactive
2317fsck's. (For those people who like to do interactive fsck's in the
2318/etc/rc scripts!?!)
2319
2320Debugfs has a few new features: the rdump command, which will do a
2321recursive dump of a directory and all of its contents, and the lcd
2322command which does a local chdir (much like the ftp command of the
2323same name). In addition, the debugfs program and the open_filesystem
2324command now takes three new options: -b and -s, which allows the
2325blocksize and superblock location to be specified, and the -c option
2326which is used in catastrophic situations where the block group
2327descriptors are corrupt. If the -c option is specified, debugfs will
2328skip trying to read in the block and inode bitmaps.
2329
2330Debufs's lsdel command was fixed to handle bad blocks in the inode
2331table.
2332
2333A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
23344 digit years.
2335
2336General improvements in error messages
2337
2338 - Mke2fs prints a sane error message if the partition size is zero
2339 (usually because the partition table wasn't reread by the
2340 kernel due to the partition being busy), instead of "invalid
2341 argument passed to ext2 library while initializing superblock".
2342
2343 - Fsck now prints more self-explanatory message if an invalid UUID=
2344 or LABEL= specification is passed to it.
2345
2346UUID library changed to use the LGPL.
2347
2348Fixed a bug in the UUID library where very rapid calls to the
2349time-based UUID generator could cause duplicate UUID's to be returned.
2350This was not a problem for e2fsprogs, but it could be a problem for
2351other users of the library.
2352
2353Make the UUID library more robust in the face of missing or an
2354improper /dev/urandom or /dev/random files.
2355
2356Added some random portability fixes for Solaris.
2357
2358Some minor man page updates.
2359
2360Fixed a memory leak in the ss library.
2361
2362
2363Programmer's notes:
2364-------------------
2365
2366We now try to use lseek64 and open64 from the LFS if possible.
2367
2368The 3rd parameter in e2p's print_flags is now a flags word, instead of
2369a boolean option.
2370
2371The mark and unmark bitmap functions now return the previous state of
2372the bit that was being changed, which is useful for some speed
2373optimizations.
2374
2375The following functions have been added to enhance the badblocks list
2376handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2377ext2fs_badblocks_equal.
2378
2379The ext2 header files now have the latest journalling fields to the
2380superblock.
2381
2382The ext2fs_mkdir function in libext2fs now properly backs out of error
2383conditions robustly.
2384
2385Cleaned up makefiles:
2386 - to cleanly compile with the -j flag.
2387 - so distclean removes all generated files.
2388 - so in case of an error while installing header files, the make aborts.
2389
2390Fix test_script so that it works correctly when compiling in the
2391source directory.
2392
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00002393The random UUID generation routine has been made slightly better in
2394the case where /dev/random doesn't exist. (Use of randomly-based UUID
2395is still not recommended if /dev/random doesn't exist, however; it's
2396better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00002397
2398Clean up the build process so it's more friendly in case of missing
2399directories.
2400
2401The ext2fs header file can now be #include'd into C++ programs.
2402
2403The e2p.h header file is now installed.
2404
2405Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
2406
2407
2408
Theodore Ts'o24ded091999-11-10 15:56:16 +00002409E2fsprogs 1.18 (November 10, 1999)
2410==================================
2411
2412Fix a core dumping bug in e2fsck if an imagic inode is present or
2413(more rarely) if the filesystem is badly corrupted enough that e2fsck
2414has to restart pass 1 processing. E2fsck now closes the filesystem
2415before freeing a large number of its data structures, so in the case
2416of future memory faults, at least the fixed filesystem will be fully
2417written out.
2418
2419If a filesystem doesn't support imagic inodes, and e2fsck discovers an
2420imagic inode, it will offer to clear the imagic flag.
2421
2422E2fsck will now offer to clear the immutable flag on special files
2423(device/socket/fifos) when running it in non-preen mode.
2424
2425E2fsck will now set the filetype when creating /lost+found, and when
2426connected orphaned inodes to /lost+found.
2427
2428Debugfs's ncheck and icheck commands now handles the case where there
2429are bad blocks in the inode table without bombing out.
2430
2431The badblocks list processing code has been made more efficiently for
2432appending a large number of (ordered) badblocks to the badblocks list.
2433
2434Some minor man page updates.
2435
2436Fsck now allows interactive e2fsck's when using fsck -As (not a common
2437mode, but some people like to do this in boot scripts for silly reasons).
2438
2439Programmer's notes:
2440-------------------
2441
2442The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
2443with the problem code convention.
2444
2445The badblocks list regression test program has been updated to work
2446with previously made API name changes.
2447
2448The ext2fs_free() command now uses the new badblocks API to avoid
2449using the compatibility layer.
2450
2451Added new regression test cases; the run_e2fsck test script now
2452supports the ability for a test case to run a prepratory command
2453before running e2fsck.
2454
Theodore Ts'o28e11941999-10-26 18:17:20 +00002455E2fsprogs 1.17 (October 26, 1999)
2456=================================
2457
2458Fixed nasty typo in fsck which caused parallelized fsck's to go into an
2459infinite loop.
2460
2461Fixed a bug in fsck where it used strncmp to compare a binary UUID,
2462thus potentially causing problems if a binary UUID contained a NULL
2463character.
2464
2465E2fsck now uses stricter checks for directory entries in pass 2:
2466zero-length filenames are not allowed; neither are 8 byte long
2467directory entries.
2468
2469The debugfs "dirty" command now clears the filesystem valid bit.
2470(Previously this just set the dirty-as-in-needs-writing-out-to-disk
2471bit in the in-core superblock image. The new functionality is more
2472what the user expects, and is more useful.)
2473
2474Added a debugging hook to test parallel fsck; if the environment
2475variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
2476will be checked in parallel when they normally would not be.
2477
2478Programmer's notes:
2479-------------------
2480
2481Fixed some #ifdef's for compilation under the Hurd OS.
2482
2483Fixed minor W2K compatibility problems.
2484
2485Fixed some miscellaneous GCC warnings.
2486
2487
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002488E2fsprogs 1.16 (October 22, 1999)
2489=================================
2490
2491Fixed a race condition bug in fsck; when printing a progress bar, if
2492checking multiple filesystems in parallel, it was possible for fsck to
2493send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
2494handler, which would cause it to terminate with a signal 10.
2495
2496E2fsck now properly handles filesystems that have the
2497INCOMPAT_FILETYPE feature turned on. It can be used to convert a
2498filesystem into using or not using FILETYPE feature.
2499
2500E2fsck now properly handles filesystems that have the IMAGIC feature
2501turned on (this is used on Linux AFS servers).
2502
2503The mke2fs program now creates filesystems that have the filetype and
2504sparse_superblock features enabled by default, unless it is run on a
2505pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
2506so there is now a new flag -O which allows the user to specify with
2507which features she would like to create the filesystem; "mke2fs -O
2508none" will create a filesystsem compatible with 2.0 kernels.
2509
2510The tune2fs program now has a -O option which allows the user to set
2511and reset "safe" filesystem features. Currently, the only ones which
2512allows to be modified are the filetype and sparse_superblock features.
2513Note setting or clearing either feature will require running e2fsck on
2514the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
2515requires that there is enough free space on the filesystem for the
2516extra superblocks which will be created by e2fsck.)
2517
2518Debugfs can now set and print filesystem features in the superblock
2519using the "features" command. Dumpe2fs will print out the complete
2520set of features when listing the superblock.
2521
2522Dumpe2fs has new options -f (force) and -h (header-only).
2523
2524Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
2525message to come up. This could happen when decrementing or
2526incrementing a link count could result in an overflow.
2527
2528Fixed a bug in e2fsck where the block count on the lost+found
2529directory would not be properly incremented when the directory was
2530expanded to the point where an indirect block needed to be allocated.
2531
2532E2fsck now makes some additional sanity checks on the superblock to
2533avoid crashing or giving a memory allocation error if some of the
2534values in the superblock are unresonable (but the superblock otherwise
2535looks valid).
2536
2537Fixed a bug in e2fsck where a very badly corrupted filesystem might
2538require two passes to completely fix the filesystem. This happened if
2539an inode claimed blocks that was part of the filesystem metadata
2540(typically, when garbage was written into an inode table or indirect
2541block, since this kind of filesystem corruption normally doesn't
2542happen otherwise).
2543
2544On the Alpha, glibc declares st_flags although it isn't actually used;
2545the configure script was improved to detect this case so that
2546e2fsprogs can avoid using the non-functional stat field.
2547
2548The manual pages were updated to use a more consistent formatting
2549style consistent with standard Unix man pages. Mke2fs's man page
2550added documentation for a few previously undocumented options.
2551
2552Fixed minor display bugs in tune2fs and mke2fs.
2553
2554Programmer's notes:
2555-------------------
2556
2557Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
2558
2559Added features to parse and print feature strings into the e2p library.
2560(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
2561
2562ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
2563whose directory entries contain proper filetype information if the
2564filesystem supports it.
2565
2566ext2fs_link() now uses the low 3 bits of its flags parameter to pass
2567the directory entry filetype information. This is used to set the
2568directory entry filetype information if the filesystem supports it.
2569
2570Fixed a bug in ext2fs_expand_dir() where the block count in a
2571directory's inode would not be properly incremented when the directory
2572was expanded to the point where an indirect block needed to be
2573allocated.
2574
2575
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002576E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002577==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002578
2579Add configuration checks so that e2fsprogs will compile cleanly on
2580Linux 2.3 kernels that have renamed i_version to i_generation.
2581
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002582E2fsck now prints a progress/completion bar (and not just a simple
2583spinner) if the -C0 option is requested or if it receives a SIGUSR1
2584signal. Fsck will automatically manage the (potentially muliple)
2585e2fsck processes to print completion bars if it is given a -C option,
2586with the right thing happening if multiple filesystems are being
2587checked in parallel.
2588
2589Mke2fs now has better automatic hueristics to determine the filesystem
2590parameters to be used for a particular filesystem. Added a new option
2591-T which allows the user to specify how the filesystem is to be used,
2592which helps mke2fs do a better job selecting the filesystem parameters.
2593
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002594Mke2fs now creates revision 1 filesystems by default, and with the
2595sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002596not understood by Linux 2.0 kernels, so they will only allow read-only
2597mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002598
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002599Fix bug where if /dev/null couldn't be opened (should never happen),
2600e2fsck would hang in a tight loop.
2601
2602Make e2fsck handle the case where /lost+found isn't a directory.
2603
2604E2fsck now uses mallinfo if it exists to get accurate statistics about
2605its memory usage.
2606
2607Fix bug in e2fsck where it wouldn't check to see if a disconnected
2608inode had any problems before connecting it to /lost+found.
2609
2610Add check to e2fsck so it makes sure that total number of inodes in
2611the filesystem is a sane number.
2612
2613Fix fencepost error when clearing an the end of the block bitmap which
2614caused the last block in the bitmap not to get cleared.
2615
2616Cleaned up a number of messages in e2fsck:
2617 * The message "Group's #'s copy of the group descriptor..."
2618 was fixed so that the correct number would be displayed.
2619 * Added missing space in the "disk write-protected" error messsage
2620 * Cleaned up the error message printed when a non-interactive
2621 e2fsck needs to abort a check because the filesystem
2622 appears to be mounted.
2623
2624Added a new command-line utility, uuidgen, which will create and print
2625a UUID.
2626
2627Make debugfs's icheck command more robust by checking to make sure an
2628inode has valid blocks before interarting over the inode's blocks.
2629
2630UUID generation now uses a random-based scheme whenever possible to
2631prevent potential privacy problems.
2632
2633Man pages for all of the UUID functions in the lirbary were added.
2634
2635Fixed bug in fsck so it won't coredump if a filesystem not in
2636/etc/fstab is given to it.
2637
2638Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2639that most of the other mount utilities understands.
2640
2641Mke2fs will make a filesystem even if it appears mounted if the force
2642option is given.
2643
2644Dumpe2fs has new command-line options which allow a filesystem expert
2645to specify the superblock and blocksize when opening a filesystem.
2646This is mainly useful when examining the remains of a toasted
2647filesystem.
2648
2649The badblocks program has been updated to display correctly on disks
2650with large block numbers.
2651
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002652The badblocks program no longer gives spurious errors when errors
2653occur on non-block boundaries, which is common if the blocksize is
2654larger than 1k.
2655
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002656Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2657MKE2FS_SYNC environment variable is set. This is to work around a VM
2658bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002659to trigger it even using a 2.2 kernel, but hopefully it will not be
2660needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002661
2662Fixed miscellaneous documentation and man pages.
2663
2664Programmer's notes:
2665-------------------
2666
2667Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2668in e2fsck's pass1.c really should have been static.
2669
2670The return value of the uuid_compare() function was changed to make it
2671match with the convetions used by strcmp, memcmp, and Paul Leach's
2672UUID sample document.
2673
2674The "make depend" process has now been made more automated; it now
2675automatically word-wraps the dependencies, and only replaces source
2676Makefile.in if there has been a change in the dependencies. Also, a
2677top-level "make depend" now recurses through all the subdirectories
2678automatically.
2679
2680The Makefile in .../util has been changed so that subst is built using
2681the native C compiler during a cross-compilation, since the subst
2682program is only used during the build process. Also add an explicit
2683rule to build util/subst by cd'ing to the correct directory and
2684running Makefile.
2685
2686The man directories are defined in terms mandir, so that the configure
2687script can override the location of the manual pages.
2688
2689The config files have been updated to recognize new machine types for
2690both the i386 and alpha families.
2691
2692Fsck has been modified so that it will accurately create an
2693fsck_instance even when the noexecute flag is set. This allows for
2694accurate debugging of the fsck pass structure. Also, when the verbose
2695flag is given twice, fsck will print debugging information about when
2696fsck is waiting for jobs to finish.
2697
2698
Theodore Ts'o14790ed1999-01-12 23:32:52 +00002699E2fsprogs 1.14 (January 9, 1999)
2700================================
2701
2702Fix the fstab parsing code so that it can handle blank lines and
2703comment characters. Also, missing pass numbers need to be treated as
2704zero.
2705
2706Fixed a bug in e2fsck where under some circumstances (when e2fsck
2707needs to restart processing after fixing an egregious inconsistency)
2708it would try to access already freed memory.
2709
2710E2fsck now prints non-printable characters in directory entries and
2711pathnames using '^' and 'M-' notation.
2712
2713Fixed chattr so that it will ignore symbolic links when doing
2714recursive descent traversals. For both chattr and lsattr, no longer
2715print the version string unless the -V option is given.
2716
2717Allow the system administrator to directly specify the number of
2718inodes desired in the filesystem, for some special cases where this is
2719necessary.
2720
2721Fix portability problems so that e2fsprogs can be compiled under Linux
27221.2 systems and Solaris systems.
2723
2724Update the config.guess file with a more recent version that will
2725identify newer Linux platforms.
2726
2727Programmer's notes
2728------------------
2729
2730Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2731an inode number of zero is passed to them.
2732
Theodore Ts'o556ad131998-12-19 08:10:58 +00002733E2fsprogs 1.13 (December 15, 1998)
2734==================================
2735
2736Fixed a bug in debugfs where an error messages weren't getting printed
2737when the ext2 library routines to read inodes returned errors in the
2738stat, cmri and rm commands.
2739
2740Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2741provided, it won't create an inode table smaller than the minimum
2742number of inodes required for a proper ext2 filesystem.
2743
2744Fsck now parses the /etc/fstab file directly (instead of using
2745getmntent()), so that it can distinguish between a missing pass number
2746field and pass number field of zero. This caused problems for
2747diskless workstations where all of the filesystems in /etc/fstab have
2748an explicit pass number of zero, and fsck could not distinguish this
2749from a /etc/fstab file with missing pass numbers.
2750
2751E2fsck will create a /lost+found directory if there isn't one in the
2752filesystem, since it's safer to create the lost+found directory before
2753it's needed.
2754
2755Fixed e2fsck so that it would detect bogus immutable inodes which
2756happen to be sockets and FIFO files, and offer to clear them.
2757
2758If a filesystem has multiple reasons why it needs to be checked, and
2759one of the reasons is that it is uncleanly mounted, e2fsck will print
2760that as the reason why the filesystem is being checked.
2761
2762Cleaned up the output routines of mke2fs so that it doesn't overflow
2763an 80 column display when formating really big filesystems.
2764
2765Added a sanity check to e2fsck to make sure that file descriptors 0,
27661, 2 are open before opening the hard disk. This avoids a problem
2767where a broken program might exec e2fsck with those file descriptors
2768closed, which would cause disastrous results if the kernel returns a
2769file descriptor for the block device which is also used by FILE *
2770stdout.
2771
2772Fixed up the e2fsck progress reporting functions so that the values
2773reliably reach 100% at the completion of all of the e2fsck passes.
2774
2775Fixed minor documentation bugs in man pages and usage messages.
2776
2777Programmer's notes:
2778-------------------
2779
2780Fixed a number of lint warnings in the ext2fs library and potential
2781portability problems from other OS's header files that might define
2782CPP macros for names like "max" and "min".
2783
2784ext2fs_badblocks_list_add() has been made more efficient when it needs
2785to grow the bad blocks list.
2786
2787Fixed a bug in e2fsck which caused it to dereference a freed pointer
2788just before exiting.
2789
2790Fixed the substition process for generating the mk_cmds and compile_et
2791scripts so that they will work outside of the build tree.
2792
2793Add sanity check to e2fsck so that if an internal routine
2794(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2795and causing a core dump. This should never happen, but...
2796
Theodore Ts'oa5696711998-07-09 05:38:07 +00002797E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002798==================================
2799
2800E2fsprogs now works with glibc (at least with the version shipped wtih
2801RedHat 5.0). The ext2fs_llseek() function should now work even with
2802i386 ELF shared libraries and if llseek() is not present. We also
2803explicitly do a configure test to see if (a) llseek is in libc, and
2804(b) if llseek is declared in the system header files. (See standard
2805complaints about libc developers don't understand the concept of
2806compatibility with previous versions of libc.)
2807
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002808The ext2fs library now writes out the block group number in each of
2809the superblock copies. This makes it easier to automatically
2810determine the starting block group of the filesystem when the block
2811group information is trashed.
2812
2813Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002814which means that e2fsprogs will ignore the high 8 bits of the
2815directory entry's name_len field, so that it can be used for other
2816purposes.
2817
2818Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2819E2fsprogs will now support filesystems with 64-bit sized files.
2820
2821Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2822
Theodore Ts'o21d53851998-02-21 03:14:50 +00002823Added new program "e2label", contributed by Andries Brouwer. E2label
2824provides an easy-to-use interface to modify the filesystem label.
2825
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002826Fixed bug so that lsattr -v works instead of producing a core dump.
2827
Theodore Ts'o21d53851998-02-21 03:14:50 +00002828Fixed a minor bug in mke2fs so that all groups with bad superblock
2829backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002830
2831Mke2fs will check the size of the device, and if the user specifies a
2832filesystem size larger than the apparent size of the device it will
2833print a warning message and ask if the user wants to proceed.
2834
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002835E2fsck has a new option -C, which sends completion information to the
2836specified file descriptor. For the most part, this is intended for
2837programs to use, although -C 0 will print a spinning character to the
2838stdout device, which may be useful for users who want to see something
2839happening while e2fsck goes about its business.
2840
Theodore Ts'o21d53851998-02-21 03:14:50 +00002841Fixed a bug in e2fsck which could cause a core dump when it needs to
2842expand the /lost+found directory, and sometimes the bitmaps haven't
2843been merged in. Also fixed a related bug where ext2fs_write_dir_block
2844was used to write out a non-directory block. (Which would be bad on a
2845non-Intel platform with byte swapping going on.)
2846
2847Fixed bug in e2fsck where it would print a "programming error" message
2848instead of correctly identifying where a bad block was in used when
2849the bad block was in a non-primary superblock or block group
2850descriptor. Also fixed a related bug when sparse superblocks are in
2851use and there is a bad block where a superblock or block group
2852descriptor would have been in a group that doesn't include a
2853superblock.
2854
2855Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2856the block group descriptor table is corrupt, it was possible to try to
2857allocate a huge array, fail, and then abort e2fsck.
2858ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2859and subsitutes reasonable values if the descriptors are obviously bogus.
2860
2861If e2fsck finds a device file which has the immutable flag set and the
2862i_blocks beyond the normal device number are non-zero, e2fsck will
2863offer to remove it, since it's probably caused by garbage in the inode
2864table.
2865
2866When opening a filesystem, e2fsck specially checks for the EROFS error
2867code, and prints a specific error message to the user which is more
2868user friendly.
2869
2870If the filesystem revision is too high, change the e2fsck to print
2871that this is either because e2fsck is out of date, or because the
2872superblock is corrupt.
2873
2874E2fsck now checks for directories that have duplicate '.' and '..'
2875entries, and fixes this corruption.
2876
2877E2fsck no longer forces a sync of the filesystem (with attendant sleep
2878calls) at all times. The ext2fs_flush() function now performs a sync
2879only if it needed to write data blocks to disk.
2880
2881Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2882certain errors would not be properly reported.
2883
2884Updated and expanded a few points in the man pages which users
2885complained wheren't explicit enough.
2886
2887Added special case byte-swapping code if compiling on the PowerPC, to
2888accomodate the strange big-endian variant of the ext2 filesystem that
2889was previously used on the PowerPC port.
2890
2891
2892Programmer's notes:
2893-------------------
2894
2895Removed C++ keywords from the ext2fs libraries so that it could be
2896compiled with C++.
2897
2898E2fsck's internal organization has now been massively reorganized so
2899that pass*.c don't have any printf statements. Instead, all problems
2900are reported through the fix_problem() abstraction interface. E2fsck
2901has also been revamped so that it can be called as a library from a
2902application.
2903
2904Added new fileio primitives in libext2fs for reading and writing
2905files on an unmounted ext2 filesystem. This interface is now used by
2906debugfs.
2907
2908Added a new libext2fs function for mapping logical block numbers of
2909a file to a physical block number.
2910
2911Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2912a block, zeros it, and updates the filesystem accounting records
2913appropriately.
2914
2915Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2916sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2917
2918The libext2fs functions now use a set of memory allocation wrapper
2919functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2920instead of malloc, free, and resize. This makes it easier for us to
2921be ported to strange environments where malloc, et. al. aren't
2922necessarily available.
2923
2924Change the libext2fs fucntion to return ext2-specific error codes
2925(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2926and depending on the existence of system error codes (such as EEXIST
2927and ENOENT).
2928
2929Renamed io.h to ext2_io.h to avoid collision with other OS's header
2930files.
2931
2932Add protection against ext2_io.h and ext2fs.h being included multiple
2933times.
2934
2935The types used for memory lengths, etc. have been made more portable.
2936In generla, the code has been made 16-bit safe. Added Mark
2937Habersack's contributed DOS disk i/o routines.
2938
2939Miscellaneous portability fixes, including not depending on char's
2940being signed.
2941
2942The io_channel structure has a new element, app_data, which is
2943initialized by the ext2fs routines to contain a copy of the filesystem
2944handle.
2945
2946ext2fs_check_directory()'s callback function may now return the error
2947EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2948really do the checking, despite the presence of the callback function.

Theodore Ts'obc210071997-06-17 05:41:36 +00002951E2fsprosg 1.11 (June 17, 1997)
2952==============================
2953
2954Fixed e2fsck to detect (previously ignored) conflicts between the
2955superblock or block group descriptors and block bitmaps, inode
2956bitmaps, and inode tables.
2957
2958Fixed bug in e2fsck so that when the message printed out when a block
2959or inode bitmap conflicts with other data, it has the correct group
2960number.
2961
2962Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2963to badblocks. This meant that not all of the filesystem was being
2964tested for bad blocks!
2965
2966Fixed an array boundary overrun case which cropped up in
2967ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2968-b 4096".
2969
2970Adjusted the number of columns printed by mke2fs when displaying the
2971superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00002972really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00002973
2974Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2975dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2976fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2977
2978Programmer's notes:
2979-------------------
2980
2981Fixed install rule in lib/ss so that ss_err.h is actually getting
2982installed.
2983
2984Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2985bassed back to the caller.
2986
2987Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2988setting the current inode number (which meant this function wasn't
2989working at all).
2990
2991Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2992blocks in the bitmap when increasing the size of the bitmap.
2993
2994Changed the initial number of blocks allocated by ext2fs_init_dblist()
2995to be more realistic.
2996
2997Added a new function ext2fs_allocate_group_table, which sets up the
2998group descriptor information (and allocates inode and block bitmaps,
2999and inode tables for a particular group). The function was created by
3000factoring out code form ext2fs_allocate_tables().
3001
3002Added a new function ext2fs_move_blocks which takes a bitmap of the
3003blocks to be moved, and moves them to another location on the
3004boardboard.
3005
3006Make the unix_io channel's io_channel_flush implementation calls sync()
3007to to flush the kernel buffers to disk.
3008
3009Added a new function ext2fs_dblist_count returns the number of
3010directory blocks in dblist.
3011
3012
Theodore Ts'oae851481997-04-29 18:13:24 +00003013E2fsprogs 1.10 (April 24, 1997)
3014===============================
3015
3016Mke2fs once again defaults to creating revision #0 filesystems, since
3017people were complaining about breaking compatibility with 1.2 kernels.
3018Warning messages were added to the mke2fs and tune2fs man pages that
3019the sparse superblock option isn't supported by most kernels yet (1.2
3020and 2.0 both don't support parse superblocks.)
3021
3022Added new flag to mke2fs, -R <raid options>, which allows the user to
3023tell mke2fs about the RAID configuration of the filesystem. Currently
3024the only supported raid option is "stride" which specifies the width
3025of the RAID stripe.
3026
3027Fixed bug in e2fsck where pass1b would bomb out if there were any
3028blocks marked bad in the inode table.
3029
3030Fixed rare bug in mke2fs where if the user had a very unlucky number
3031of blocks in a filesystem (probability less than .002) the resulting
3032filesystem would be corrupt in the last block group.
3033
3034Fixed bug where if e2fsck tried to allocate a block to fix a
3035filesystem corruption problem and the filesystem had no free blocks,
3036ext2fs_new_block() would loop forever.
3037
3038The configure script now checks explicitly to see if "-static" works,
3039since that can't be assumed to be true --- RedHat doesn't install
3040libc-static by default.
3041
3042Fixed bug in libext2's block iterator functions where under some
3043cirmcustances, file with holes would cause the bcount parameter to the
3044callback function to be incorrect. This bug didn't affect any of
3045e2fsprogs programs, but it was discovered by Paul Mackerras, the
3046author of the PPC boot loader.
3047
3048Removed use of static variables to store the inode cache in libext2fs.
3049This caused problems if more than one filesystem was accessed via
3050libext2fs (static variables in libraries are generally a bad idea).
3051Again, this didn't affect e2fsprogs programs, but it was discovered by
3052Paul Mackerras.
3053
3054Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
3055will compile cleanly with 1.2.13 kernels (even with a.out shared
3056libraries!)
3057
3058Programmer's notes:
3059-------------------
3060
3061Added new functions to duplicate an ext2 filesystem handle, and its
3062associated substructure. New functions: ext2fs_dup_handle(),
3063ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
3064Other structures, such as the io_channel and the inode_cache, now have
3065a ref count so that they only get freed when they are no longer used
3066by any filesystem handle. (These functions were added as part of the
3067development effort for an ext2 resizer).
3068
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00003069E2fsprogs 1.09 (April 14, 1997)
3070===============================
3071
3072Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
3073accidentally introduced in the 1.08 release. The overhead calculation
3074was accidentally removed, which caused ext2fs_initialize() to not
3075notice when the filesystem size needed to be adjusted down because
3076there wasn't enough space in the last block group.
3077
3078Fixed bug in version parsing library routine; it was always parsing
3079the library version string, instead of using the passed-in string.
3080
3081Clarified chattr man page.
3082
Theodore Ts'o24757fa1997-04-29 17:39:27 +00003083E2fsprogs 1.08 (April 10, 1997)
3084===============================
3085
3086E2fsck 1.07 was very slow when checking very large filesystems with a
3087lot of files that had hard links (i.e., news spools). This was fixed
3088by seriously revamping the icount abstraction. Added a formal test
3089suite for the icount abstraction.
3090
3091Debugfs now has a "-l" option to the "ls" command, which lists the
3092inode number, permissions, owner, group, size, and name of the files
3093in the directory.
3094
3095Fix a bug in e2fsck where when a directory had its blocks moved to
3096another location during the pass 1b processing, the directory block
3097list wasn't updated, so pass 2 wouldn't check (and correct) the
3098correct directory block.
3099
3100E2fsck will now treat inodes which contain blocks which are claimed by
3101the filesystem metadata by treating them as multiply claimed blocks.
3102This way, the data in those blocks can be copied to a new block during
3103the pass 1b--1d processing.
3104
3105E2fsck will attempt to determine the correct superblock number and
3106display it in the diagnostic and warning messages if possible.
3107
3108Add support for a new (incompatible) feature, "sparse_super". This
3109feature reduces the number of blocks which contain copies of backup
3110superblocks and block group descriptors. (It is only an incompatible
3111feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3112support a new -s option; e2fsck will recognize filesystems built with
3113this feature turned on.
3114
3115E2fsck now checks the library to make sure is the correct version,
3116using new library functions. (This helps to diagnose incorrectly
3117installed e2fsprogs distributions.)
3118
3119Dumpe2fs now prints more information; its now prints the the
3120filesystem revision number, the filesystem sparse_super feature (if
3121present), the block ranges for each block group, and the offset from
3122the beginning of the block group.
3123
3124Mke2fs now distributes the inode and block bitmap blok so that the
3125won't be concentrated in one or two disks in RAID/striping setups.
3126Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3127choose the largest blocks per group that be chosen. (For 2k blocks,
3128you can have up to 16384 blocks/group; for 4k blocks, you can have up
3129to 32768 blocks/group.) Previously mke2fs would not allow
3130specification of more than 8192 blocks per group, even if you were
3131using a 2k or 4k block group.
3132
3133Programmer's notes:
3134-------------------
3135
3136Added a new function ext2fs_create_icount2() which takes a "hint"
3137argument. This hint argument presets the icount array with the list
3138of inodes which actually need to be in the icount array. This really
3139helps to speed up e2fsck.
3140
3141Added a new function ext2fs_icount_validate() which checks the rep
3142invariant for the icount structure. This is used mostly for testing.
3143
3144The error mesasage given when a bad inode number is passed to
3145test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3146EXT2FS_UNMARK_ERROR).
3147
3148Added a new function ext2fs_set_dir_block which sets the block of a
3149dblist entry, given the directory inode and blockcnt.
3150
3151Added a new function ext2fs_get_library_version() which returns the
3152current library version, and ext2fs_parse_version_string() which
3153returns a version number based on a e2fsprogs version string.
3154
3155The icount functions will return EINVAL if the passed in inode number
3156is out of bounds.
3157
Theodore Ts'o21c84b71997-04-29 16:15:03 +00003158E2fsprogs 1.07 (March 9, 1997)
3159==============================
3160
3161E2fsck is now uses much less memory when checking really large
3162filesystems (or rather, filesystems with a large number of inodes).
3163Previously a filesystem with 1 million inodes required 4 megabytes of
3164memory to store inode count statistics; that storage requirement has
3165now been reduced to roughly half a megabyte.
3166
3167E2fsck can now properly deal with bad blocks appearing inside the
3168inode table. Instead of trying to relocate the inode table (which
3169often failed because there wasn't enough space), the inodes in the bad
3170block are marked as in use.
3171
3172E2fsck will automatically try to use the backup superblocks if the
3173primary superblocks have a bad magic number or have missing meta-data
3174blocks (or meta-data blocks which are out of range).
3175
3176E2fsck's pass 3 has been made more efficient; most noticeable on
3177filesystems with a very large number of directories.
3178
3179Completely revamped e2fsck's system of printing problem reports. It
3180is now table driven, to make them more easily customizeable and
3181extendable. Error messages which can be printed out during preen mode
3182are now one line long.
3183
3184Fixed e2fsck's filesystem swapping code so that it won't try to swap
3185fast symbolic links or deleted files.
3186
3187Fixed e2fsck core dumping when fixing a filesystem which has no
3188directories (not even a root directory).
3189
3190Added a check to e2fsck to make sure that the length of every
3191directory entry is a multiple of 4 (since the kernel complains if it
3192isn't).
3193
3194Added a check to e2fsck to make sure that a directory entry isn't a
3195link to the root directory, since that isn't allowed.
3196
3197Added a check to e2fsk to now make sure the '.' and '..' directory
3198entries are null terminated, since the 2.0 kernel requires it.
3199
3200Added check to write_bitmaps() to make sure the superblock doesn't get
3201trashed if the inode or block bitmap is marked as being block zero.
3202
3203Added checking of the new feature set fields in the superblock, to
3204avoid dealing with new filesystem features that this package wasn't
3205set up to handle.
3206
3207Fixed a fencepost error in ext2fs_new_block() which would occasionally
3208try to allocate a block beyond the end of a filesystem.
3209
3210When the UUID library picks a random IEEE 802 address (because it
3211can't find one from a network card), it sets the multicast bit, to
3212avoid conflicting with a legitimate IEEE 802 address.
3213
3214Mke2fs now sets the root directory's owner to be the real uid of the
3215user running mke2fs. If the real uid is non-zero, it also sets
3216the group ownership of the root directory to be the real group-id of
3217the user running mke2fs.
3218
3219Mke2fs now has more intelligent error checking when it is given a
3220non-existent device.
3221
3222When badblocks is given the -vv option, it now updates the block that
3223it is currently testing on every block.
3224
3225Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3226currently correctly if PATH wasn't already set.
3227
3228Shared libraries now built with dependencies. This allows the shared
3229library files to be used with dlopen(); it also makes the transition
3230to libc 6 easier, since ld.so can tell which libc a particular shared
3231library expects to use.
3232
3233Programmer's notes:
3234-------------------
3235
3236Added new abstraction (defined in dblist.c) for maintaining a list of
3237blocks which belongs to directories. This is used in e2fsck and other
3238programs which need to iterate over all directories.
3239
3240Added new functions which test to see if a contiguous range of blocks
3241(or inodes) are available. (ext2fs_*_bitmap_range).
3242
3243Added new function (ext2_inode_has_valid_blocks) which returns true if
3244an inode has valid blocks. (moved from e2fsck code).
3245
3246Added new function (ext2fs_allocate_tables) which allocates the
3247meta-data blocks as part of initializing a filesystem. (moved from
3248mke2fs code).
3249
3250Added a new I/O manager for testing purposes. It will either allow a
3251program to intercept I/O requests, or print debugging messages to
3252trace the activity of a program using the I/O manager.
3253
3254The badblocks_list functions now store the bad blocks in a sorted
3255order, and use a binary search to speed up badblocks_list_test.
3256
3257The inode scan function ext2fs_get_next_inode() may now return a soft
3258error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
3259those cases where part of an inode table is missing or there is a bad
3260block in the inode table.
3261
3262Added a new function (ext2fs_block_iterate2) which adds new arguments to
3263the callback function to return a pointer (block and offset) to the
3264reference of the block.
3265
3266Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
3267application to jump to a particular block group while doing an inode
3268scan.
3269
3270The badblocks list functions were renamed from badblocks_* to
3271ext2fs_badblocks_*. Backwards compatibility functions are available
3272for now, but programs should be modified to use the new interface.
3273
3274Some of the library functions were reorganized into separate files to
3275reduce the size of some programs which statically link against the
3276ext2 library.
3277
3278Put in some miscellaneous fixes for the Alpha platform.
3279
Theodore Ts'o5c576471997-04-29 15:29:49 +00003280
3281E2fsprogs 1.06 (October 7, 1996)
3282================================
3283
3284Fixed serious bug in e2fsck: if the block descriptors are bad, don't
3285smash the backup copies in ext2fs_close(). (The problem was that when
3286e2fsck -p discovered the problem, while it was closing the filesystem
3287and exiting, it was also blowing away the backup superblocks on the
3288disk, which was less than friendly.) We now make it the case that we
3289only write out the backup superblock and the back block descriptors if
3290the filesystem is completely free from problems.
3291
3292Fixed a bug in block_interate in the lib/ext2fs library which caused
3293e2fsck to fail on GNU Hurd-created filesystems.
3294
3295Add support for Linux/FT's bootloader, which actually uses
3296EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
3297to clear the inode.
3298
3299Add support for the "A" (no atime update) attribute. (Note: this
3300attribute is not yet in production kernels.)
3301
3302The test suite is not automatically run when doing a "make all" from
3303the top level directory. Users should manually run "make check" if
3304they wish to run the test suite.
3305
3306Upon a preenhalt(), make the printed message more explicit that
3307running e2fsck "MANAULLY" means without the -p or -a options.
3308
3309In e2fsck, if a disconnected inode is zero-length, offer to clear it
3310instead of offering to connect it to lost+found.
3311
3312In e2fsck, if a filesystem was just unmounted uncleanly, and needs
3313e2fsck to be run over it, change e2fsck to explicitly display this
3314fact.
3315
3316For dumpe2fs and e2fsck, cause the -V option to print out which
3317version of the ext2fs library is actually getting used. (This will
3318help detect mismatches of using a 1.06 utility with a 1.05 library,
3319etc.)
3320
3321Programmers' notes:
3322-------------------
3323
3324EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
3325the naming convention.
3326
3327In ext2fs_initialize(), make sure the description for the inode bitmap
3328is correctly initialize.
3329
3330Fixed minor type typo in ext2fs_allocate_generic_bitmap();
3331
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003332E2fsprogs 1.05 (September 7, 1996)
3333==================================
3334
3335Add support for new fields in the ext2 superblock --- volume name,
3336volume UUID, and last mounted field. Dumpe2fs displays these fields,
3337tune2fs and mke2fs allows you to set them. E2fsck will automatically
3338generate a UUID for those volumes that don't have them.
3339
3340Put in support for e2fsck to recognize HURD specific ext2 features ---
3341most notably, the translator block. The e2fsprogs tools will now use
3342the creator_os field in the superblock to correctly handle different
3343OS-specific variants of the ext2 filesystem.
3344
3345E2fsck now fixes inodes which have a the deletion time set, but which
3346have a non-zero i_link_count field by offering to clear the deletion
3347time. Previously e2fsck assumed that the inode was deleted (per 0.3c
3348ext2 kernel behavior) and offered to unlink the file.
3349
3350If e2fsck sets the clean bit, but nothing else, set the exit code
3351FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
3352set the filesystem valid bit when it was previously cleared. :-) This
3353was needed to make the HURD fsck driver happy.
3354
3355If the user refuses to attach an unattached inode, e2fsck will no
3356longer set the inode's link count. Otherwise, the inode would end up
3357getting marked as unused, which might cause loss of data later.
3358
3359Make the message issued by e2fsck when the superblock is corrupt less
3360confusing for users. It now mentions that another reason for the
3361"corrupt superblock" message might be that the partition might not be
3362an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
3363
3364Make the libext2 library more robuest so that e2fsck won't coredump on
3365an illegal superblock where the blocksize is zero. (f_crashdisk is
3366the test case).
3367
3368By default, create filesystems where the default checkinterval is 6
3369months (180 days). Linux servers can be robust enough that 20 reboots
3370can be a long, long time.
3371
3372Added configure flag --enable-old-bitops, which forces the bitops to
3373use the old (native) bitmask operations. By default on the sparc
3374platform, the standard ext2 bit ordering is now used.
3375
3376Added a new feature to e2fsck to byte-swap filesystems; this can be
3377used to convert old m68k filesystems to use the standard byte-order
3378storage for the superblock, inodes, and directory blocks. This
3379function is invoked by using the '-s' option to e2fsck.
3380
3381Debugfs's "dump" command has been enhanced so that it writes out the
3382exact size of the file so that the nulls at the end of the file are
3383eliminated. The command also accept a new "-p" option which will
3384attempt preserve to preserve the ownernship, permissions, and
3385file modification/access times.
3386
3387Debugfs has two new options, -f and -R. The -R option allows the user
3388to execute a single debugfs command from the command line. The -f
3389option allows the user to specify a "command file" containing debugfs
3390commands which will get executed.
3391
3392Dumpe2fs now pretty prints the check interval, instead of just
3393printing the check interval as a number of seconds.
3394
3395Fix bugs in debugfs: the params command when no filesystem is opened
3396no longer causes a core dump. It is now possible to unlink a file
3397when a pathame containing a '/' is specified.
3398
3399Tune2fs has a new -C option which sets the number of times the
3400filesystem has been mounted.
3401
3402Fix the chattr '-v' option so that it actually works. Chattr was
3403being buggy about the -v option parsing.
3404
3405Programmers' notes:
3406-------------------
3407
3408The directory lib/uuid contains a set of library routines to generate
3409DCE compatible UUIDs.
3410
3411Extended ext2fs_namei() to handle symbolic links. Added new function
3412ext2fs_nami_follow() which will follow last symbolic link in the case
3413where the pathname points to a sym link.
3414
3415The ext2fs_block_iterate function will now return the HURD translator
3416block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
3417iterator to return data blocks only. The ext2fs.h file now defines
3418constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
3419BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
3420count field of the iterator callback function.
3421
3422The test script driver now takes an optional second argument, which is
3423the test case to be run. This allows you to run a test case without
3424needing to run the entire test suite.
3425
3426On Linux ELF systems, install the .so files in the correct places
3427(/usr/lib). The .so files must be stored in the same directory as the
3428.a files.
3429
3430Fixed miscellaneous HURD compilation issues with header file being
3431included in the right order.
3432
3433Fixed debugfs so that it resets optind to zero, not one, since setting
3434optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +00003437E2fsprogs 1.04 (May 16, 1996)
3438=============================
3439
3440First "official" (1.03 was a limited release only) to support building
3441e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
3442kernels).
3443
3444This package includes a RPM specs file, that it can be built using the
3445RedHat Package Manager.
3446
3447E2fsck now prints a hint that if there are lots of incorrectly located
3448inode bitmaps, block bitmaps, and inode table blocks, the user might
3449want to try using e2fsck -b 8193 first, to see if that fares any
3450better.
3451
3452For ext2 filesystem written with the hurd, debugfs will now print out
3453the translator field when printing an inode structure.
3454
3455Lots of miscellaneous linking/installation cleanups:
3456
3457 Libraries are now linked using a relative pathname, instead of
3458 relying on -L working correct. It doesn't, in many cases, including
3459 current versions of GNU ld. This guarantees that the build tree is
3460 linking with the right libraries, instead of the ones installed in
3461 /usr/lib.
3462
3463 Header files, man pages, and the et/ss shell scripts are now
3464 generated using a custom substitution script, instead of relying on
3465 the configure script. This prevents needless recompilation of
3466 files; in addition, the custom substitution script is much faster.
3467
3468 e2fsck may now be linked dynamically, by using the
3469 --enable-dynamic-e2fsck flag to configure. This is not recommended,
3470 since it increases e2fsck's dependence on other files, but some
3471 people need to save disk space, and other critical programs on their
3472 systems were being linked dynamically anyway.
3473
3474 Programs such as fsck which didn't need to be linked against
3475 libext2fs (or mke2fs which didn't need to be linked against libe2p)
3476 only link against libraries they actually need. Otherwise, those
3477 programs would require the presense of libraries that otherwise
3478 could be removed from a rescuse diskette.
3479
3480 The ss include files are now installed correctly so they can
3481 actually be used by another package.
3482
3483 If the profiling libraries are built, they are now installed on a
3484 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00003487E2fsprogs 1.03 (March 27, 1996)
3488===============================
3489
3490Change the m68k bit numbering for bitmasks to match the bit numbering
3491used by all other ext2 implementations. (This change was requested by
3492the m68k kernel development team.)
3493
3494Support (in-development) filesystem format revision which supports
3495(among other things) dynamically sized inodes.
3496
3497Fixed a bug in the ext2 library so that an intelligent error is
3498returned if mke2fs is run with a ridiculously small number of blocks
3499for a partition.
3500
3501Fixed a bug in the ext2 library which required that the device be
3502openable in read/write mode in order to determine its size. This
3503caused e2fsck -n to require read/write access when it was not
3504previously necessary.
3505
3506Fixed a bug in e2fsck which casued it to occasionally fail the test
3507suite depending on which version of the floating point library it was
3508using.
3509
3510Fixed a bug in e2fsck so that it now halts with a fatal error when
3511certain superblock consistency checks fail. Previously it continued
3512running e2fsck, with some potential confusing/damaging consequences.
3513
3514Added new flag to fsck which allows the root to be checked in parallel
3515with other filesytems. This is not the safest thing in the world to
3516do, but some system administrators really wanted it.
3517
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00003518Fixed -Wall flames in lib/ss.
3519
Theodore Ts'o74becf31997-04-26 14:37:06 +00003520
3521E2fsprogs 1.02 (January 16, 1996)
3522=================================
3523
3524Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
3525
3526Change e2fsck to print statistics of how many non-contiguous files are
3527on the system. Note that a file which is larger than 8k blocks, it is
3528guaranteed to be non-contiguous.
3529
3530In mke2fs, print a warning message if a user tries to format a whole
3531disk (/dev/hda versus /dev/hda1). If a user really wants to format a
3532whole disk, the -F (force) option forces mke2fs to format a whole disk
3533as a filesytem.
3534
3535Fix a bug in fsck where in some cases it might start checking
3536partitions in the next pass before it finishes checking partitions in
3537the current pass. This still won't cause two partitions on the same
3538disk will be checked, so it's rarely a problem in real life.
3539
3540Patch lsattr so that it won't hang when checking a named pipe.
3541
3542Minor compilation fixes:
3543 * Fix the order of libraries that were linked in debugfs.
3544 * Allow the sources to be compiled with -ansi turned on.
