4=====================================================================
5
61. Fix printout of the 'Connection to' message in dump/restore.
7 Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
8 bug report and its fix.
b630baf0 9
c43794b1
SP
102. Fix dump -w/-W output for filesystems having the last backup
11 level equal to 0. Thanks to Pascal Bouchareine
12 <kalou@users.sourceforge.net> for reporting the bug.
13
7f7d329e
SP
143. Enable restore to handle restoring onto a different SELinux
15 policy from the dump. Thanks to Tony Nelson
16 <tony_nelson@users.sourceforge.net> for the patch.
17 (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845

204. Fix EA set failures when restoring immutable files. Thanks
21 to Andrew Kroeger for the patch.
22
4a9a33ef
SP
235. Fix "mode file too large" errors when restoring huge backups.
24 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
25 report.

370f48b6 27Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
54ebfc01 28=====================================================================
b630baf0
SP
29
301. Fix restore of dumped Access Control Lists. The previous
31 code for EA works fine, but ACLs needed conversion from the
32 ext2/3 disk format to posix_acl format before restoring.
f30c53e5 33
cb6d3f79
SP
342. Fix some issues with restoration of EA on big endian
35 platforms.
36
26ce8fc8
SP
373. Fix restore when the symtab is over 2GB in size.
38
df3d2ef9
SP
394. Made the directory hash indexing an optional feature,
40 accessible by the '-H' option of restore, and disable it
41 by default.
42
0c78942b
SP
435. Fixed dump to not include extended attributes information
44 in the toc (archive) file which confused restore -t.
45
84182f10
SP
46Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
47=================================================================
f30c53e5
SP
48
491. Changed restore to emit warnings (instead of emitting a fatal
50 error) if a file (or a directory) is unavailable for a
51 comparision (if the user doesn't have the necessary permissions
52 to access it for example). Thanks to Kenneth Porter
53 <shiva@sewingwitch.com> for the bug report.
35ed8cf8 54
979da669
SP
552. Re-done the 'do not save directory entries to non-dumped inodes
56 (excluded from dump)' feature. The previous implementation
57 worked well for excluded directories but not for regular files.
58 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
59 report.
60
1ba0c4bb
SP
613. Fixed a bug in dump where the tape size was miscalculated when
62 the user used -d/-s to specify the tape characteristics. Thanks
63 to Philip Goisman <goisman@physics.arizona.edu> for reporting
64 the bug.
65
c21722b0
SP
664. Fixed another bug introduced in restore with the hashtree
67 implementation. This one caused restore to stop saying
68 "removenode: non-empty directory" in some cases.
69
cca7148b
SP
705. Added support for dumping and restoring ext2/3 extended
71 attributes (EA), like the access control lists (ACL) or
72 the security labels used by SELinux.
73
debbffbc
SP
74Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
75======================================================================
35ed8cf8
SP
76
771. The newly added dump_on_cd_3 example was buggy, replace it
78 with an updated version from Andrew Basterfield
79 <bob@cemetery.homeunix.org>.
b79d20f1 80
30e8407d
SP
812. Made restore to chdir() back into the initial directory when
82 dumping core while aborting a comparision operation. The
83 previous behaviour was to write the corefile at the root of
84 the directory being compared, which could very well be
85 read only and preventing the corefile generation. Thanks
86 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
87
b43981b3
SP
883. Silenced the failure to call fgetflags() when comparing an
89 entry which has no ext2 attributes (as in lsattr()).
90
68415469
SP
914. Fix a brown paper bug in restore -C which broke restore and
92 caused modifications on the filesystem being compared
93 (directories containing a file with the same name as the
94 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
95 <shiva@sewingwitch.com> for finding the bug and helping me
96 reproduce it.
97
18dc6e86
SP
985. Made restore -C force the -N flag (no writing allowed on
99 the disk) in order to prevent more bugs like the above one.
100
cdd136ec
SP
101Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
102=====================================================================
b79d20f1
SP
103
1041. Fix a couple of troff syntax bugs in the man pages.
105 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 106
0556ca22
SP
1072. Made restore use either libncurses or libtermcap, depending
108 on which one is available at configure time.
109
7d422735
SP
1103. Fixed restore negative size display bug when comparing a
111 dump containing files over 2GB. Thanks to Steve Bonds
112 <sbonds@users.sourceforge.net> for the bug report.
113
585ca01a
SP
1144. Do not save directory entries to non-dumped inodes
115 (excluded from dump). This will eliminate the 'missing
116 file' warnings when doing 'restore -C'.
117
241ddca3
SP
1185. Fix dump crash when backuping a huge (2TB) filesystem,
119 due to a bogus calculation on the inode map size.
120 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
121 submitting the bug and testing the fix.
122
47acd076
SP
1236. Fix a problem in restore where the final \0 in the symbolic
124 link names could have been lost, generating corrupt filenames.
125 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
126 bug.
127
741eb204
SP
1287. Implemented a hash list for the directory names in restore.
129 The linear list used before caused problems in interactive
130 restores when dealing with directories having thousands of
131 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
132 for reporting the bug.
133
a55ce914
SP
1348. Improved restore -C, this time including the directory
135 attributes into the comparision.
136
1379. Made restore understand tapes containing EA/ACLs (which will
138 be dumped by the next version of dump). In this version
139 extended attributes on the tape are ignored, for full EA/ACL
140 support wait for the next version or try the experimental EA
141 patch.
142
498a402f
SP
143Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
144==================================================================
d7783603
SP
145
1461. Added the --enable-staticz configure option which enables
147 dump and restore to be linked with static versions of
148 libz and libbz2 (and dynamic versions of all other libraries).
149 This will make Debian users happy, because libz and libbz2
150 were the only needed libraries living in /usr, all the
151 others live in /lib. In case of system emergency, it is
152 better not to have to rely on an extra filesystem.
153 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 154
b3f55532
SP
1552. Fix compilation on (at least the Linux Debian port to) AMD64.
156 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
157 that are also defined by <linux/types.h> (<asm/types.h>) and
158 they conflict).
159
1f2c193e
SP
1603. Make dump's reading of the dumpdates file a bit more robust,
161 preventing dump from crashing when the dumpdates file has
162 been modified by hand.
163
e1e4be20
SP
1644. Fixed some offset calculations in dump code which could
165 lead to "bread lseek errors" on large filesystems. Thanks
166 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
167 reporting this bug and debugging the issue.
168
c9e4e868
SP
1695. Made dump use the blkid library when searching for devices
170 by label or uuid instead of dump's own routines.
171
97be3358
SP
1726. Corrected a bug in dump where a wrong LABEL=... line in
173 /etc/fstab could prevent dump from dumping unrelated
174 filesystems. Thanks to Bruce Lowekamp
175 <lowekamp@users.sourceforge.net> for reporting the bug.
176
ddf54486
SP
177Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
178====================================================================
e0267986
SP
179
1801. Fixed dump compilation with old gcc versions. Thanks to
181 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 182
75654eee
SP
1832. Fixed some warnings (howmany, roundup, powerof2 redefined)
184 when compiling against a recent glibc version.
185
43e6ea49
SP
1863. Fixed a bug in restore preventing the read of a dump tape
187 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
188 <phiggins@transzap.com> for reporting the bug and providing
189 the test case.
190
d435f57f
SP
1914. Changed dump to enable the creation of volumes of different
192 sizes in a single run (make -B accept a list of values).
193 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
194
e1ba02ef
SP
1955. Use the glibc provided minor() and major() macros instead
196 of our own bitmask implementation. This should be safe for
197 when the major/minor namespace will migrate to 32 bits.
198 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
199 the bug.
200
ae6919a7
SP
2016. Made explicit in the dump man page that dump will not create
202 a remote file, it will only write to an already existing one.
203
4acaf865
SP
2047. Another try at making size estimates better again.
205
956756f2
SP
2068. Put back the inconditional running of the end-of-tape
207 script which was changed in 0.434 to be run only when -M
208 or multiple -f were NOT specified. Some users rely on this
209 feature even when it is combined with -M/-f.
210
e4e31ce9
SP
2119. Fixed restore when restoring huge backups (where rstdir...
212 temporary files are over 2GB). Thanks to
213 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
214 debugging the issue and making the patch.
215
cc7747eb
SP
21610. Made restore understand FreeBSD UFS2 tapes. Thanks to
217 David <vrtin@users.sourceforge.net> for submitting the bug
218 and providing a test case.
219
28ba5cae
SP
22011. Made dump work with an arbitrary integer level (no more 10
221 levels only limitation). Thanks to Matthew
222 <msvincen@midway.uchicago.edu> for the patch.
223
dcac75e9
SP
224Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
225=======================================================================
8ad151aa
SP
226
2271. Added a note in the dump man page saying that the default
228 blocksize can be 32 if -d is used with a high density argument.
229 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
230 for the patch.
ed194aec 231
008af419
SP
2322. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
233 LDFLAGS environment variables. Thanks to Arcady Genkin
234 <antipode@users.sourceforge.net> for reporting the bug.
235
0d4dfd07 2363. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
237 to be excluded, rather than a hardcoded maximum. Thanks to
238 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
239
0d4dfd07
SP
2404. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
241 and -D_USE_BSD_SIGNAL defines in configure in order to solve
242 64bit build problems because quad_t is redifined with a
243 different signature. Thanks to Mike Harris <mharris@redhat.com>
244 for reporting this bug.
245
5d8d264f 2465. Made restore build on Solaris, making possible to
d1925e0c
SP
247 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
248 <uwe@ugsoft.de> for the patch.
249
2506. Made an extension in the dump tape format capable of saving
251 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
252 wrote the extension and contributed the restore code back
253 into this codebase. The same extension mechanism will be
254 used in the future to save ACLs...
255
2567. Made rmt work correctly with regard to QFA and local/remote
257 files and tapes. The remote access will however work only
258 when the dump provided rmt version is used. If you want to
259 use another rmt server, please do not use the QFA feature.
5d8d264f 260 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 261
b564cb84
SP
262Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
263====================================================================
ed194aec
SP
264
2651. Fixed the INSTALL file to reflect the actual install paths.
266 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
267 reporting the bug.
4bb009da 268
d3e542e7
SP
2692. Fixed the configure script to only check for headers presence
270 instead of trying to compile them. This should fix issues
271 with old build environments. Thanks to Kari Lempiainen
272 <kari@funky.pp.fi> for reporting the bug.
273
1176b3c1
SP
2743. Fixed restore to correctly ignore sockets when comparing
275 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
276 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
277
2784. Fixed restore to correctly access the archive file (-A argument)
279 even when using a remote tape. Thanks to Fabrice Bellet
280 <fabrice@bellet.info> for reporting the bug.
1176b3c1 281
900bffdb
SP
2825. Fixed (again) handling of long (largefile) seeks in rmt.
283 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
284 the bug.
285
6d834d25
SP
2866. Fixed restore corner case when dealing with large block sizes
287 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
288 <fabrice@bellet.info> for reporting the bug.
289
cdef84ca
SP
2907. Fixed a bug preventing dump to access a filesystem having
291 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
292 for reporting the bug.
293
3458b64d
SP
2948. Made dump store dump dates using explicit timezones, fixing a
295 problem with incremental dumps if the timezone is modified
296 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
297 the bug report and the patch.
298
2be77799
SP
2999. Fixed a bug encountered when dumping individual files (not full
300 filesystems or directories) and dangling symbolic links happen
301 to be in the list of files. For as far as dump is concerned,
302 dangling symbolic links are allowed, and are dumped as is.
303 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
304 bug and providing the fix.
305
c3f69f06
SP
30610. Fixed open and creation modes and permissions for QFA and
307 table-of-contents files in dump and restore. Thanks to
308 Philippe Troin <phil@fifi.org> for the patch.
309
31011. Fixed the archive file descriptor handling enabling it to be 0.
311 This can happen in some cases when shell redirections are used.
312 Thanks to Philippe Troin <phil@fifi.org> for the patch.
313
31412. Delayed the opening of archive file until after suid had been
315 dropped (fixing a possible security issue if dump is suid).
316 Thanks to Philippe Troin <phil@fifi.org> for the patch.
317
31813. Fixed the 'S' command handling in the rmt client part.
319 Thanks to Philippe Troin <phil@fifi.org> for the patch.
320
32114. Modified the end-of-tape script handling to print out statistics
322 (and stop the timer) before launching the eot script. Also, the eot
323 script does not get run anymore when using -M (which makes sense) or
324 when multiple tapes are listed on the command line
325 (-f tape0,tape1,tapen) (which also makes sense).
326 Thanks to Philippe Troin <phil@fifi.org> for the patch.
327
e1abc9ce
SP
32815. Relicensed dump/restore under the 'revised' BSD license, as per
329 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
330
206f768c
SP
33116. Added LZO compression to dump. This new compression method has
332 the advantage of being super fast, thus not killing tape streaming
333 on slow machines. Thanks to Helmut Jarausch
334 <jarausch@igpm.rwth-aachen.de> for the patch and to
335 Markus Oberhumer <markus@oberhumer.com> for giving special permission
336 to include his miniLZO project (GPL licensed) in dump/restore.
337
e2392789
SP
33817. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
339 <ant@notatla.demon.co.uk> for reporting the bugs.
340
cdfe1392
SP
34118. Added a special rmt version which can do encryption when writing
342 to tape. Read examples/encrypted_rmt/README for details on
343 how to enable and configure it. Thanks to Ken Lalonde
344 <ken@globalremit.com> for the patch.
345
61e9d4ff
SP
34619. Made dump work with 2.5 kernel end of tape early warning semantics.
347 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
348
8c95cc30
SP
34920. Fixed a bug which caused dump -w|-W not to work anymore, because
350 the fs_freq and fs_passno fields in /etc/mtab are always set
351 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
352 reporting the bug.
353
cbdba727 354Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
355=======================================================================
356
3571. Added a note in the restore man page clarifying the question
358 'set the permissions on the current directory ?' asked by
359 restore at the end of treatment in -i and -x modes.
d86089d1 360
c898ca7a
SP
3612. Fixed the endianess issues when reading compressed tapes.
362 Thanks to Dark Force <daq4th@users.sourceforge.net> for
363 reporting this bug and providing test cases.
364
a028bdc8
SP
3653. Fixed the "ACL won't be dumped" warning message (which showed
366 an extra, unrelated error message). Thanks to Dragan Krnic
367 <dkrnic@lycos.com> for reporting this bug.
368
a8a6a503 3694. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
370 when searching for filesystem paths. Also fixed some problems
371 caused by binding mounts or multiple block device mounts.
372 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
373 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
374 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
375 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 376
3211c85b
SP
3775. Made dump's -I option accept the value '0' meaning all the
378 read errors will be ignored. This can be useful when running
379 dump from unattended sessions (like cron jobs). Thanks to
380 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
381
7fcd6df5
SP
3826. Fixed the output of dump to indicate 'blocks' instead of
383 'tape blocks' in the various messages (blocks are always
384 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
385 made it clearly print the current blocksize at the start of
386 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
387 the suggestions.
388
5bf65105
SP
3897. Made rmt understand long (largefiles) seeks.
390
dbb649e8
SP
3918. Fixed build with very old versions of libext2fs, where
392 EXT2_FT_* constants were undefined.
393
c92d83ae
SP
3949. Made dump accept the dumpdates path on the command line
395 (-D file option) instead of using only the hardcoded one.
396 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
397 suggestion.
398
1daf06b9
SP
39910. Enabled rmt, LFS, readline, QFA options by default in
400 ./configure. Updated the configure process (new versions
401 of config.guess, config.sub etc).
402
51c11d00
SP
403Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
404=======================================================================
d86089d1
SP
405
4061. Changed dump to use fcntl(F_SETLK) style locking instead
407 of flock() when locking the dumpdates file. With the old
408 locking scheme, a local user having read rights on the
409 dumpdates file could be able to do a Denial of Service attack
410 on dump. In order to lock the dumpdates file with the new
411 scheme, the user would need to have write access on the file.
412 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
413 reporting the bug (originally a bugtraq post).
ba3af39e 414
2f562f4e
SP
4152. Fixed interactive 'ls' which caused spurious errors warnings
416 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
417 <jorgen_ostling@users.sourceforge.net> for reporting this
418 bug.
419
1c736b78
SP
4203. Fixed dump's estimate when dealing with sparse inodes.
421
876861d2
SP
4224. Modified dump to allow setting a blocksize bigger than 32kB
423 (raised the limit to 1024kB), because newer hardware needs
424 this for proper operation. Thanks to Dirk Traenapp
425 <dtraenapp@users.sourceforge.net> for reporting this.

4275. Fixed a bug causing Dump to stop and report an error if an
428 inode number in the exclude file was followed by some amount
429 of whitespace. Thanks to Jeffrey Sofferin
430 <sofferin@users.sourceforge.net> for reporting this bug.

4326. Fixed a bug which caused restore, in some particular cases,
433 to ask some 'scary' questions and leave a bunch of RSTTMP
434 directories behind when restoring incremental tapes. Thanks
435 to Philippe Troin <phil@fifi.org> for reporting this bug and
436 providing the test cases.

4387. Changed the wording when inodes are excluded from dump:
439 replaced 'Added inode 7 to exclude list' with
440 'Excluding inode 7 (resize inode) from dump', as suggested
441 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.

4461. Fixed rmt open flags transmission (GNU's symbolic syntax over
447 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi

4531. Made dump print out the ext2 logical block number in case of a read
454 error, which can be given as an argument to debugfs' ncheck command,
455 in order to find out the affected inode. Added note about this
456 usage in dump's man page.

4582. Fixed a problem in restore when reading tapes written on big
459 endian machines with very old versions of dump. The patch was
460 contributed by George Helffrich <george@geology.bristol.ac.uk>.

463 and compression. Thanks to Georg Lippold

4664. Added a new set of examples in dump_on_cd_2 directory, based
467 on dump_on_cd examples but somewhat enhanced, supporting DVD
468 media, and localized in english and german. Thanks to
469 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

4715. Made dump save 32 bit UID/GID. Internally, this was achieved
472 by switching from the old BSD inode format to the new BSD
473 inode format, which means that the tape format was changed.
474 However, since all restore versions out there should
475 transparently support both inode formats, the change should
476 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
477 reporting the bug.

4878. Rewrote entirely the man pages using the tmac.an macro
488 package (Linux man page format) instead of the original BSD
489 format. They should be now cleaner and easier to modify.

4941. Fixed a problem in the rmt ioctl command, where ioctl's issued from
495 non Linux clients were misinterpreted. The description of the problem
496 (incompatible numbering in Linux mtio opcodes) is documented at
497 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
