3Changes between versions 0.4b40 and 0.4b41 (released ???????????)
4=================================================================
5
61. Fix restore of dumped Access Control Lists. The previous
7 code for EA works fine, but ACLs needed conversion from the
8 ext2/3 disk format to posix_acl format before restoring.
f30c53e5 9
cb6d3f79
SP
102. Fix some issues with restoration of EA on big endian
11 platforms.
12
26ce8fc8
SP
133. Fix restore when the symtab is over 2GB in size.
14
df3d2ef9
SP
154. Made the directory hash indexing an optional feature,
16 accessible by the '-H' option of restore, and disable it
17 by default.
18
0c78942b
SP
195. Fixed dump to not include extended attributes information
20 in the toc (archive) file which confused restore -t.
21
84182f10
SP
22Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
23=================================================================
f30c53e5
SP
24
251. Changed restore to emit warnings (instead of emitting a fatal
26 error) if a file (or a directory) is unavailable for a
27 comparision (if the user doesn't have the necessary permissions
28 to access it for example). Thanks to Kenneth Porter
29 <shiva@sewingwitch.com> for the bug report.
35ed8cf8 30
979da669
SP
312. Re-done the 'do not save directory entries to non-dumped inodes
32 (excluded from dump)' feature. The previous implementation
33 worked well for excluded directories but not for regular files.
34 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
35 report.
36
1ba0c4bb
SP
373. Fixed a bug in dump where the tape size was miscalculated when
38 the user used -d/-s to specify the tape characteristics. Thanks
39 to Philip Goisman <goisman@physics.arizona.edu> for reporting
40 the bug.
41
c21722b0
SP
424. Fixed another bug introduced in restore with the hashtree
43 implementation. This one caused restore to stop saying
44 "removenode: non-empty directory" in some cases.
45
cca7148b
SP
465. Added support for dumping and restoring ext2/3 extended
47 attributes (EA), like the access control lists (ACL) or
48 the security labels used by SELinux.
49
debbffbc
SP
50Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
51======================================================================
35ed8cf8
SP
52
531. The newly added dump_on_cd_3 example was buggy, replace it
54 with an updated version from Andrew Basterfield
55 <bob@cemetery.homeunix.org>.
b79d20f1 56
30e8407d
SP
572. Made restore to chdir() back into the initial directory when
58 dumping core while aborting a comparision operation. The
59 previous behaviour was to write the corefile at the root of
60 the directory being compared, which could very well be
61 read only and preventing the corefile generation. Thanks
62 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
63
b43981b3
SP
643. Silenced the failure to call fgetflags() when comparing an
65 entry which has no ext2 attributes (as in lsattr()).
66
68415469
SP
674. Fix a brown paper bug in restore -C which broke restore and
68 caused modifications on the filesystem being compared
69 (directories containing a file with the same name as the
70 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
71 <shiva@sewingwitch.com> for finding the bug and helping me
72 reproduce it.
73
18dc6e86
SP
745. Made restore -C force the -N flag (no writing allowed on
75 the disk) in order to prevent more bugs like the above one.
76
cdd136ec
SP
77Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
78=====================================================================
b79d20f1
SP
79
801. Fix a couple of troff syntax bugs in the man pages.
81 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 82
0556ca22
SP
832. Made restore use either libncurses or libtermcap, depending
84 on which one is available at configure time.
85
7d422735
SP
863. Fixed restore negative size display bug when comparing a
87 dump containing files over 2GB. Thanks to Steve Bonds
88 <sbonds@users.sourceforge.net> for the bug report.
89
585ca01a
SP
904. Do not save directory entries to non-dumped inodes
91 (excluded from dump). This will eliminate the 'missing
92 file' warnings when doing 'restore -C'.
93
241ddca3
SP
945. Fix dump crash when backuping a huge (2TB) filesystem,
95 due to a bogus calculation on the inode map size.
96 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
97 submitting the bug and testing the fix.
98
47acd076
SP
996. Fix a problem in restore where the final \0 in the symbolic
100 link names could have been lost, generating corrupt filenames.
101 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
102 bug.
103
741eb204
SP
1047. Implemented a hash list for the directory names in restore.
105 The linear list used before caused problems in interactive
106 restores when dealing with directories having thousands of
107 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
108 for reporting the bug.
109
a55ce914
SP
1108. Improved restore -C, this time including the directory
111 attributes into the comparision.
112
1139. Made restore understand tapes containing EA/ACLs (which will
114 be dumped by the next version of dump). In this version
115 extended attributes on the tape are ignored, for full EA/ACL
116 support wait for the next version or try the experimental EA
117 patch.
118
498a402f
SP
119Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
120==================================================================
d7783603
SP
121
1221. Added the --enable-staticz configure option which enables
123 dump and restore to be linked with static versions of
124 libz and libbz2 (and dynamic versions of all other libraries).
125 This will make Debian users happy, because libz and libbz2
126 were the only needed libraries living in /usr, all the
127 others live in /lib. In case of system emergency, it is
128 better not to have to rely on an extra filesystem.
129 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 130
b3f55532
SP
1312. Fix compilation on (at least the Linux Debian port to) AMD64.
132 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
133 that are also defined by <linux/types.h> (<asm/types.h>) and
134 they conflict).
135
1f2c193e
SP
1363. Make dump's reading of the dumpdates file a bit more robust,
137 preventing dump from crashing when the dumpdates file has
138 been modified by hand.
139
e1e4be20
SP
1404. Fixed some offset calculations in dump code which could
141 lead to "bread lseek errors" on large filesystems. Thanks
142 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
143 reporting this bug and debugging the issue.
144
c9e4e868
SP
1455. Made dump use the blkid library when searching for devices
146 by label or uuid instead of dump's own routines.
147
97be3358
SP
1486. Corrected a bug in dump where a wrong LABEL=... line in
149 /etc/fstab could prevent dump from dumping unrelated
150 filesystems. Thanks to Bruce Lowekamp
151 <lowekamp@users.sourceforge.net> for reporting the bug.
152
ddf54486
SP
153Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
154====================================================================
e0267986
SP
155
1561. Fixed dump compilation with old gcc versions. Thanks to
157 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 158
75654eee
SP
1592. Fixed some warnings (howmany, roundup, powerof2 redefined)
160 when compiling against a recent glibc version.
161
43e6ea49
SP
1623. Fixed a bug in restore preventing the read of a dump tape
163 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
164 <phiggins@transzap.com> for reporting the bug and providing
165 the test case.
166
d435f57f
SP
1674. Changed dump to enable the creation of volumes of different
168 sizes in a single run (make -B accept a list of values).
169 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
170
e1ba02ef
SP
1715. Use the glibc provided minor() and major() macros instead
172 of our own bitmask implementation. This should be safe for
173 when the major/minor namespace will migrate to 32 bits.
174 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
175 the bug.
176
ae6919a7
SP
1776. Made explicit in the dump man page that dump will not create
178 a remote file, it will only write to an already existing one.
179
4acaf865
SP
1807. Another try at making size estimates better again.
181
956756f2
SP
1828. Put back the inconditional running of the end-of-tape
183 script which was changed in 0.434 to be run only when -M
184 or multiple -f were NOT specified. Some users rely on this
185 feature even when it is combined with -M/-f.
186
e4e31ce9
SP
1879. Fixed restore when restoring huge backups (where rstdir...
188 temporary files are over 2GB). Thanks to
189 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
190 debugging the issue and making the patch.
191
cc7747eb
SP
19210. Made restore understand FreeBSD UFS2 tapes. Thanks to
193 David <vrtin@users.sourceforge.net> for submitting the bug
194 and providing a test case.
195
28ba5cae
SP
19611. Made dump work with an arbitrary integer level (no more 10
197 levels only limitation). Thanks to Matthew
198 <msvincen@midway.uchicago.edu> for the patch.
199
dcac75e9
SP
200Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
201=======================================================================
8ad151aa
SP
202
2031. Added a note in the dump man page saying that the default
204 blocksize can be 32 if -d is used with a high density argument.
205 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
206 for the patch.
ed194aec 207
008af419
SP
2082. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
209 LDFLAGS environment variables. Thanks to Arcady Genkin
210 <antipode@users.sourceforge.net> for reporting the bug.
211
0d4dfd07 2123. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
213 to be excluded, rather than a hardcoded maximum. Thanks to
214 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
215
0d4dfd07
SP
2164. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
217 and -D_USE_BSD_SIGNAL defines in configure in order to solve
218 64bit build problems because quad_t is redifined with a
219 different signature. Thanks to Mike Harris <mharris@redhat.com>
220 for reporting this bug.
221
5d8d264f 2225. Made restore build on Solaris, making possible to
d1925e0c
SP
223 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
224 <uwe@ugsoft.de> for the patch.
225
2266. Made an extension in the dump tape format capable of saving
227 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
228 wrote the extension and contributed the restore code back
229 into this codebase. The same extension mechanism will be
230 used in the future to save ACLs...
231
2327. Made rmt work correctly with regard to QFA and local/remote
233 files and tapes. The remote access will however work only
234 when the dump provided rmt version is used. If you want to
235 use another rmt server, please do not use the QFA feature.
5d8d264f 236 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 237
b564cb84
SP
238Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
239====================================================================
ed194aec
SP
240
2411. Fixed the INSTALL file to reflect the actual install paths.
242 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
243 reporting the bug.
4bb009da 244
d3e542e7
SP
2452. Fixed the configure script to only check for headers presence
246 instead of trying to compile them. This should fix issues
247 with old build environments. Thanks to Kari Lempiainen
248 <kari@funky.pp.fi> for reporting the bug.
249
1176b3c1
SP
2503. Fixed restore to correctly ignore sockets when comparing
251 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
252 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
253
2544. Fixed restore to correctly access the archive file (-A argument)
255 even when using a remote tape. Thanks to Fabrice Bellet
256 <fabrice@bellet.info> for reporting the bug.
1176b3c1 257
900bffdb
SP
2585. Fixed (again) handling of long (largefile) seeks in rmt.
259 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
260 the bug.
261
6d834d25
SP
2626. Fixed restore corner case when dealing with large block sizes
263 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
264 <fabrice@bellet.info> for reporting the bug.
265
cdef84ca
SP
2667. Fixed a bug preventing dump to access a filesystem having
267 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
268 for reporting the bug.
269
3458b64d
SP
2708. Made dump store dump dates using explicit timezones, fixing a
271 problem with incremental dumps if the timezone is modified
272 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
273 the bug report and the patch.
274
2be77799
SP
2759. Fixed a bug encountered when dumping individual files (not full
276 filesystems or directories) and dangling symbolic links happen
277 to be in the list of files. For as far as dump is concerned,
278 dangling symbolic links are allowed, and are dumped as is.
279 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
280 bug and providing the fix.
281
c3f69f06
SP
28210. Fixed open and creation modes and permissions for QFA and
283 table-of-contents files in dump and restore. Thanks to
284 Philippe Troin <phil@fifi.org> for the patch.
285
28611. Fixed the archive file descriptor handling enabling it to be 0.
287 This can happen in some cases when shell redirections are used.
288 Thanks to Philippe Troin <phil@fifi.org> for the patch.
289
29012. Delayed the opening of archive file until after suid had been
291 dropped (fixing a possible security issue if dump is suid).
292 Thanks to Philippe Troin <phil@fifi.org> for the patch.
293
29413. Fixed the 'S' command handling in the rmt client part.
295 Thanks to Philippe Troin <phil@fifi.org> for the patch.
296
29714. Modified the end-of-tape script handling to print out statistics
298 (and stop the timer) before launching the eot script. Also, the eot
299 script does not get run anymore when using -M (which makes sense) or
300 when multiple tapes are listed on the command line
301 (-f tape0,tape1,tapen) (which also makes sense).
302 Thanks to Philippe Troin <phil@fifi.org> for the patch.
303
e1abc9ce
SP
30415. Relicensed dump/restore under the 'revised' BSD license, as per
305 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
306
206f768c
SP
30716. Added LZO compression to dump. This new compression method has
308 the advantage of being super fast, thus not killing tape streaming
309 on slow machines. Thanks to Helmut Jarausch
310 <jarausch@igpm.rwth-aachen.de> for the patch and to
311 Markus Oberhumer <markus@oberhumer.com> for giving special permission
312 to include his miniLZO project (GPL licensed) in dump/restore.
313
e2392789
SP
31417. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
315 <ant@notatla.demon.co.uk> for reporting the bugs.
316
cdfe1392
SP
31718. Added a special rmt version which can do encryption when writing
318 to tape. Read examples/encrypted_rmt/README for details on
319 how to enable and configure it. Thanks to Ken Lalonde
320 <ken@globalremit.com> for the patch.
321
61e9d4ff
SP
32219. Made dump work with 2.5 kernel end of tape early warning semantics.
323 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
324
8c95cc30
SP
32520. Fixed a bug which caused dump -w|-W not to work anymore, because
326 the fs_freq and fs_passno fields in /etc/mtab are always set
327 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
328 reporting the bug.
329
cbdba727 330Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
331=======================================================================
332
3331. Added a note in the restore man page clarifying the question
334 'set the permissions on the current directory ?' asked by
335 restore at the end of treatment in -i and -x modes.
d86089d1 336
c898ca7a
SP
3372. Fixed the endianess issues when reading compressed tapes.
338 Thanks to Dark Force <daq4th@users.sourceforge.net> for
339 reporting this bug and providing test cases.
340
a028bdc8
SP
3413. Fixed the "ACL won't be dumped" warning message (which showed
342 an extra, unrelated error message). Thanks to Dragan Krnic
343 <dkrnic@lycos.com> for reporting this bug.
344
a8a6a503 3454. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
346 when searching for filesystem paths. Also fixed some problems
347 caused by binding mounts or multiple block device mounts.
348 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
349 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
350 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
351 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 352
3211c85b
SP
3535. Made dump's -I option accept the value '0' meaning all the
354 read errors will be ignored. This can be useful when running
355 dump from unattended sessions (like cron jobs). Thanks to
356 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
357
7fcd6df5
SP
3586. Fixed the output of dump to indicate 'blocks' instead of
359 'tape blocks' in the various messages (blocks are always
360 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
361 made it clearly print the current blocksize at the start of
362 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
363 the suggestions.
364
5bf65105
SP
3657. Made rmt understand long (largefiles) seeks.
366
dbb649e8
SP
3678. Fixed build with very old versions of libext2fs, where
368 EXT2_FT_* constants were undefined.
369
c92d83ae
SP
3709. Made dump accept the dumpdates path on the command line
371 (-D file option) instead of using only the hardcoded one.
372 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
373 suggestion.
374
1daf06b9
SP
37510. Enabled rmt, LFS, readline, QFA options by default in
376 ./configure. Updated the configure process (new versions
377 of config.guess, config.sub etc).
378
51c11d00
SP
379Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
380=======================================================================
d86089d1
SP
381
3821. Changed dump to use fcntl(F_SETLK) style locking instead
383 of flock() when locking the dumpdates file. With the old
384 locking scheme, a local user having read rights on the
385 dumpdates file could be able to do a Denial of Service attack
386 on dump. In order to lock the dumpdates file with the new
387 scheme, the user would need to have write access on the file.
388 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
389 reporting the bug (originally a bugtraq post).
ba3af39e 390
2f562f4e
SP
3912. Fixed interactive 'ls' which caused spurious errors warnings
392 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
393 <jorgen_ostling@users.sourceforge.net> for reporting this
394 bug.
395
1c736b78
SP
3963. Fixed dump's estimate when dealing with sparse inodes.
397
876861d2
SP
3984. Modified dump to allow setting a blocksize bigger than 32kB
399 (raised the limit to 1024kB), because newer hardware needs
400 this for proper operation. Thanks to Dirk Traenapp
401 <dtraenapp@users.sourceforge.net> for reporting this.
402
b8d848c9
SP
4035. Fixed a bug causing Dump to stop and report an error if an
404 inode number in the exclude file was followed by some amount
405 of whitespace. Thanks to Jeffrey Sofferin
406 <sofferin@users.sourceforge.net> for reporting this bug.
407
e531c442
SP
4086. Fixed a bug which caused restore, in some particular cases,
409 to ask some 'scary' questions and leave a bunch of RSTTMP
410 directories behind when restoring incremental tapes. Thanks
411 to Philippe Troin <phil@fifi.org> for reporting this bug and
412 providing the test cases.
413
c993d83a
SP
4147. Changed the wording when inodes are excluded from dump:
415 replaced 'Added inode 7 to exclude list' with
416 'Excluding inode 7 (resize inode) from dump', as suggested
417 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
418
cbc7fd6a 419Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
420===================================================================
421
4221. Fixed rmt open flags transmission (GNU's symbolic syntax over
423 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
424 <eros@lamel.bo.cnr.it> for reporting the bug.

4291. Made dump print out the ext2 logical block number in case of a read
430 error, which can be given as an argument to debugfs' ncheck command,
431 in order to find out the affected inode. Added note about this
432 usage in dump's man page.

4342. Fixed a problem in restore when reading tapes written on big
435 endian machines with very old versions of dump. The patch was
436 contributed by George Helffrich <george@geology.bristol.ac.uk>.

4424. Added a new set of examples in dump_on_cd_2 directory, based
443 on dump_on_cd examples but somewhat enhanced, supporting DVD
444 media, and localized in english and german. Thanks to
445 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

4475. Made dump save 32 bit UID/GID. Internally, this was achieved
448 by switching from the old BSD inode format to the new BSD
449 inode format, which means that the tape format was changed.
450 However, since all restore versions out there should
451 transparently support both inode formats, the change should
452 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
453 reporting the bug.

4556. Fixed a lot of warnings in the code shown when compiling
456 with 'gcc -W'. Thanks to Matthias Andree
457 <matthias.andree@stud.uni-dortmund.de> for reporting this.

4638. Rewrote entirely the man pages using the tmac.an macro
464 package (Linux man page format) instead of the original BSD
465 format. They should be now cleaner and easier to modify.

4701. Fixed a problem in the rmt ioctl command, where ioctl's issued from
471 non Linux clients were misinterpreted. The description of the problem
472 (incompatible numbering in Linux mtio opcodes) is documented at
473 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
