3Changes between versions 0.4b41 and 0.4b42 (released xxxxxxxxxxxxxxx)
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
370f48b6 14Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
54ebfc01 15=====================================================================
b630baf0
SP
16
171. Fix restore of dumped Access Control Lists. The previous
18 code for EA works fine, but ACLs needed conversion from the
19 ext2/3 disk format to posix_acl format before restoring.
f30c53e5 20
cb6d3f79
SP
212. Fix some issues with restoration of EA on big endian
22 platforms.
23
26ce8fc8
SP
243. Fix restore when the symtab is over 2GB in size.
25
df3d2ef9
SP
264. Made the directory hash indexing an optional feature,
27 accessible by the '-H' option of restore, and disable it
28 by default.
29
0c78942b
SP
305. Fixed dump to not include extended attributes information
31 in the toc (archive) file which confused restore -t.
32
84182f10
SP
33Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
34=================================================================
f30c53e5
SP
35
361. Changed restore to emit warnings (instead of emitting a fatal
37 error) if a file (or a directory) is unavailable for a
38 comparision (if the user doesn't have the necessary permissions
39 to access it for example). Thanks to Kenneth Porter
40 <shiva@sewingwitch.com> for the bug report.
35ed8cf8 41
979da669
SP
422. Re-done the 'do not save directory entries to non-dumped inodes
43 (excluded from dump)' feature. The previous implementation
44 worked well for excluded directories but not for regular files.
45 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
46 report.
47
1ba0c4bb
SP
483. Fixed a bug in dump where the tape size was miscalculated when
49 the user used -d/-s to specify the tape characteristics. Thanks
50 to Philip Goisman <goisman@physics.arizona.edu> for reporting
51 the bug.
52
c21722b0
SP
534. Fixed another bug introduced in restore with the hashtree
54 implementation. This one caused restore to stop saying
55 "removenode: non-empty directory" in some cases.
56
cca7148b
SP
575. Added support for dumping and restoring ext2/3 extended
58 attributes (EA), like the access control lists (ACL) or
59 the security labels used by SELinux.
60
debbffbc
SP
61Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
62======================================================================
35ed8cf8
SP
63
641. The newly added dump_on_cd_3 example was buggy, replace it
65 with an updated version from Andrew Basterfield
66 <bob@cemetery.homeunix.org>.
b79d20f1 67
30e8407d
SP
682. Made restore to chdir() back into the initial directory when
69 dumping core while aborting a comparision operation. The
70 previous behaviour was to write the corefile at the root of
71 the directory being compared, which could very well be
72 read only and preventing the corefile generation. Thanks
73 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
74
b43981b3
SP
753. Silenced the failure to call fgetflags() when comparing an
76 entry which has no ext2 attributes (as in lsattr()).
77
68415469
SP
784. Fix a brown paper bug in restore -C which broke restore and
79 caused modifications on the filesystem being compared
80 (directories containing a file with the same name as the
81 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
82 <shiva@sewingwitch.com> for finding the bug and helping me
83 reproduce it.
84
18dc6e86
SP
855. Made restore -C force the -N flag (no writing allowed on
86 the disk) in order to prevent more bugs like the above one.
87
cdd136ec
SP
88Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
89=====================================================================
b79d20f1
SP
90
911. Fix a couple of troff syntax bugs in the man pages.
92 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 93
0556ca22
SP
942. Made restore use either libncurses or libtermcap, depending
95 on which one is available at configure time.
96
7d422735
SP
973. Fixed restore negative size display bug when comparing a
98 dump containing files over 2GB. Thanks to Steve Bonds
99 <sbonds@users.sourceforge.net> for the bug report.
100
585ca01a
SP
1014. Do not save directory entries to non-dumped inodes
102 (excluded from dump). This will eliminate the 'missing
103 file' warnings when doing 'restore -C'.
104
241ddca3
SP
1055. Fix dump crash when backuping a huge (2TB) filesystem,
106 due to a bogus calculation on the inode map size.
107 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
108 submitting the bug and testing the fix.
109
47acd076
SP
1106. Fix a problem in restore where the final \0 in the symbolic
111 link names could have been lost, generating corrupt filenames.
112 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
113 bug.
114
741eb204
SP
1157. Implemented a hash list for the directory names in restore.
116 The linear list used before caused problems in interactive
117 restores when dealing with directories having thousands of
118 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
119 for reporting the bug.
120
a55ce914
SP
1218. Improved restore -C, this time including the directory
122 attributes into the comparision.
123
1249. Made restore understand tapes containing EA/ACLs (which will
125 be dumped by the next version of dump). In this version
126 extended attributes on the tape are ignored, for full EA/ACL
127 support wait for the next version or try the experimental EA
128 patch.
129
498a402f
SP
130Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
131==================================================================
d7783603
SP
132
1331. Added the --enable-staticz configure option which enables
134 dump and restore to be linked with static versions of
135 libz and libbz2 (and dynamic versions of all other libraries).
136 This will make Debian users happy, because libz and libbz2
137 were the only needed libraries living in /usr, all the
138 others live in /lib. In case of system emergency, it is
139 better not to have to rely on an extra filesystem.
140 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 141
b3f55532
SP
1422. Fix compilation on (at least the Linux Debian port to) AMD64.
143 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
144 that are also defined by <linux/types.h> (<asm/types.h>) and
145 they conflict).
146
1f2c193e
SP
1473. Make dump's reading of the dumpdates file a bit more robust,
148 preventing dump from crashing when the dumpdates file has
149 been modified by hand.
150
e1e4be20
SP
1514. Fixed some offset calculations in dump code which could
152 lead to "bread lseek errors" on large filesystems. Thanks
153 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
154 reporting this bug and debugging the issue.
155
c9e4e868
SP
1565. Made dump use the blkid library when searching for devices
157 by label or uuid instead of dump's own routines.
158
97be3358
SP
1596. Corrected a bug in dump where a wrong LABEL=... line in
160 /etc/fstab could prevent dump from dumping unrelated
161 filesystems. Thanks to Bruce Lowekamp
162 <lowekamp@users.sourceforge.net> for reporting the bug.
163
ddf54486
SP
164Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
165====================================================================
e0267986
SP
166
1671. Fixed dump compilation with old gcc versions. Thanks to
168 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 169
75654eee
SP
1702. Fixed some warnings (howmany, roundup, powerof2 redefined)
171 when compiling against a recent glibc version.
172
43e6ea49
SP
1733. Fixed a bug in restore preventing the read of a dump tape
174 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
175 <phiggins@transzap.com> for reporting the bug and providing
176 the test case.
177
d435f57f
SP
1784. Changed dump to enable the creation of volumes of different
179 sizes in a single run (make -B accept a list of values).
180 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
181
e1ba02ef
SP
1825. Use the glibc provided minor() and major() macros instead
183 of our own bitmask implementation. This should be safe for
184 when the major/minor namespace will migrate to 32 bits.
185 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
186 the bug.
187
ae6919a7
SP
1886. Made explicit in the dump man page that dump will not create
189 a remote file, it will only write to an already existing one.
190
4acaf865
SP
1917. Another try at making size estimates better again.
192
956756f2
SP
1938. Put back the inconditional running of the end-of-tape
194 script which was changed in 0.434 to be run only when -M
195 or multiple -f were NOT specified. Some users rely on this
196 feature even when it is combined with -M/-f.
197
e4e31ce9
SP
1989. Fixed restore when restoring huge backups (where rstdir...
199 temporary files are over 2GB). Thanks to
200 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
201 debugging the issue and making the patch.
202
cc7747eb
SP
20310. Made restore understand FreeBSD UFS2 tapes. Thanks to
204 David <vrtin@users.sourceforge.net> for submitting the bug
205 and providing a test case.
206
28ba5cae
SP
20711. Made dump work with an arbitrary integer level (no more 10
208 levels only limitation). Thanks to Matthew
209 <msvincen@midway.uchicago.edu> for the patch.
210
dcac75e9
SP
211Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
212=======================================================================
8ad151aa
SP
213
2141. Added a note in the dump man page saying that the default
215 blocksize can be 32 if -d is used with a high density argument.
216 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
217 for the patch.
ed194aec 218
008af419
SP
2192. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
220 LDFLAGS environment variables. Thanks to Arcady Genkin
221 <antipode@users.sourceforge.net> for reporting the bug.
222
0d4dfd07 2233. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
224 to be excluded, rather than a hardcoded maximum. Thanks to
225 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
226
0d4dfd07
SP
2274. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
228 and -D_USE_BSD_SIGNAL defines in configure in order to solve
229 64bit build problems because quad_t is redifined with a
230 different signature. Thanks to Mike Harris <mharris@redhat.com>
231 for reporting this bug.
232
5d8d264f 2335. Made restore build on Solaris, making possible to
d1925e0c
SP
234 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
235 <uwe@ugsoft.de> for the patch.
236
2376. Made an extension in the dump tape format capable of saving
238 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
239 wrote the extension and contributed the restore code back
240 into this codebase. The same extension mechanism will be
241 used in the future to save ACLs...
242
2437. Made rmt work correctly with regard to QFA and local/remote
244 files and tapes. The remote access will however work only
245 when the dump provided rmt version is used. If you want to
246 use another rmt server, please do not use the QFA feature.
5d8d264f 247 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 248
b564cb84
SP
249Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
250====================================================================
ed194aec
SP
251
2521. Fixed the INSTALL file to reflect the actual install paths.
253 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
254 reporting the bug.
4bb009da 255
d3e542e7
SP
2562. Fixed the configure script to only check for headers presence
257 instead of trying to compile them. This should fix issues
258 with old build environments. Thanks to Kari Lempiainen
259 <kari@funky.pp.fi> for reporting the bug.
260
1176b3c1
SP
2613. Fixed restore to correctly ignore sockets when comparing
262 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
263 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
264
2654. Fixed restore to correctly access the archive file (-A argument)
266 even when using a remote tape. Thanks to Fabrice Bellet
267 <fabrice@bellet.info> for reporting the bug.
1176b3c1 268
900bffdb
SP
2695. Fixed (again) handling of long (largefile) seeks in rmt.
270 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
271 the bug.
272
6d834d25
SP
2736. Fixed restore corner case when dealing with large block sizes
274 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
275 <fabrice@bellet.info> for reporting the bug.
276
cdef84ca
SP
2777. Fixed a bug preventing dump to access a filesystem having
278 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
279 for reporting the bug.
280
3458b64d
SP
2818. Made dump store dump dates using explicit timezones, fixing a
282 problem with incremental dumps if the timezone is modified
283 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
284 the bug report and the patch.
285
2be77799
SP
2869. Fixed a bug encountered when dumping individual files (not full
287 filesystems or directories) and dangling symbolic links happen
288 to be in the list of files. For as far as dump is concerned,
289 dangling symbolic links are allowed, and are dumped as is.
290 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
291 bug and providing the fix.
292
c3f69f06
SP
29310. Fixed open and creation modes and permissions for QFA and
294 table-of-contents files in dump and restore. Thanks to
295 Philippe Troin <phil@fifi.org> for the patch.
296
29711. Fixed the archive file descriptor handling enabling it to be 0.
298 This can happen in some cases when shell redirections are used.
299 Thanks to Philippe Troin <phil@fifi.org> for the patch.
300
30112. Delayed the opening of archive file until after suid had been
302 dropped (fixing a possible security issue if dump is suid).
303 Thanks to Philippe Troin <phil@fifi.org> for the patch.
304
30513. Fixed the 'S' command handling in the rmt client part.
306 Thanks to Philippe Troin <phil@fifi.org> for the patch.
307
30814. Modified the end-of-tape script handling to print out statistics
309 (and stop the timer) before launching the eot script. Also, the eot
310 script does not get run anymore when using -M (which makes sense) or
311 when multiple tapes are listed on the command line
312 (-f tape0,tape1,tapen) (which also makes sense).
313 Thanks to Philippe Troin <phil@fifi.org> for the patch.
314
e1abc9ce
SP
31515. Relicensed dump/restore under the 'revised' BSD license, as per
316 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
317
206f768c
SP
31816. Added LZO compression to dump. This new compression method has
319 the advantage of being super fast, thus not killing tape streaming
320 on slow machines. Thanks to Helmut Jarausch
321 <jarausch@igpm.rwth-aachen.de> for the patch and to
322 Markus Oberhumer <markus@oberhumer.com> for giving special permission
323 to include his miniLZO project (GPL licensed) in dump/restore.
324
e2392789
SP
32517. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
326 <ant@notatla.demon.co.uk> for reporting the bugs.
327
cdfe1392
SP
32818. Added a special rmt version which can do encryption when writing
329 to tape. Read examples/encrypted_rmt/README for details on
330 how to enable and configure it. Thanks to Ken Lalonde
331 <ken@globalremit.com> for the patch.
332
61e9d4ff
SP
33319. Made dump work with 2.5 kernel end of tape early warning semantics.
334 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
335
8c95cc30
SP
33620. Fixed a bug which caused dump -w|-W not to work anymore, because
337 the fs_freq and fs_passno fields in /etc/mtab are always set
338 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
339 reporting the bug.
340
cbdba727 341Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
342=======================================================================
343
3441. Added a note in the restore man page clarifying the question
345 'set the permissions on the current directory ?' asked by
346 restore at the end of treatment in -i and -x modes.
d86089d1 347
c898ca7a
SP
3482. Fixed the endianess issues when reading compressed tapes.
349 Thanks to Dark Force <daq4th@users.sourceforge.net> for
350 reporting this bug and providing test cases.
351
a028bdc8
SP
3523. Fixed the "ACL won't be dumped" warning message (which showed
353 an extra, unrelated error message). Thanks to Dragan Krnic
354 <dkrnic@lycos.com> for reporting this bug.
355
a8a6a503 3564. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
357 when searching for filesystem paths. Also fixed some problems
358 caused by binding mounts or multiple block device mounts.
359 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
360 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
361 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
362 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 363
3211c85b
SP
3645. Made dump's -I option accept the value '0' meaning all the
365 read errors will be ignored. This can be useful when running
366 dump from unattended sessions (like cron jobs). Thanks to
367 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
368
7fcd6df5
SP
3696. Fixed the output of dump to indicate 'blocks' instead of
370 'tape blocks' in the various messages (blocks are always
371 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
372 made it clearly print the current blocksize at the start of
373 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
374 the suggestions.
375
5bf65105
SP
3767. Made rmt understand long (largefiles) seeks.
377
dbb649e8
SP
3788. Fixed build with very old versions of libext2fs, where
379 EXT2_FT_* constants were undefined.
380
c92d83ae
SP
3819. Made dump accept the dumpdates path on the command line
382 (-D file option) instead of using only the hardcoded one.
383 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
384 suggestion.
385
1daf06b9
SP
38610. Enabled rmt, LFS, readline, QFA options by default in
387 ./configure. Updated the configure process (new versions
388 of config.guess, config.sub etc).
389
51c11d00
SP
390Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
391=======================================================================
d86089d1
SP
392
3931. Changed dump to use fcntl(F_SETLK) style locking instead
394 of flock() when locking the dumpdates file. With the old
395 locking scheme, a local user having read rights on the
396 dumpdates file could be able to do a Denial of Service attack
397 on dump. In order to lock the dumpdates file with the new
398 scheme, the user would need to have write access on the file.
399 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
400 reporting the bug (originally a bugtraq post).
ba3af39e 401
2f562f4e
SP
4022. Fixed interactive 'ls' which caused spurious errors warnings
403 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
404 <jorgen_ostling@users.sourceforge.net> for reporting this
405 bug.
406
1c736b78
SP
4073. Fixed dump's estimate when dealing with sparse inodes.
408
876861d2
SP
4094. Modified dump to allow setting a blocksize bigger than 32kB
410 (raised the limit to 1024kB), because newer hardware needs
411 this for proper operation. Thanks to Dirk Traenapp
412 <dtraenapp@users.sourceforge.net> for reporting this.
413
b8d848c9
SP
4145. Fixed a bug causing Dump to stop and report an error if an
415 inode number in the exclude file was followed by some amount
416 of whitespace. Thanks to Jeffrey Sofferin
417 <sofferin@users.sourceforge.net> for reporting this bug.
418
e531c442
SP
4196. Fixed a bug which caused restore, in some particular cases,
420 to ask some 'scary' questions and leave a bunch of RSTTMP
421 directories behind when restoring incremental tapes. Thanks
422 to Philippe Troin <phil@fifi.org> for reporting this bug and

4257. Changed the wording when inodes are excluded from dump:
426 replaced 'Added inode 7 to exclude list' with
427 'Excluding inode 7 (resize inode) from dump', as suggested
428 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.

4331. Fixed rmt open flags transmission (GNU's symbolic syntax over
434 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi

4401. Made dump print out the ext2 logical block number in case of a read
441 error, which can be given as an argument to debugfs' ncheck command,
442 in order to find out the affected inode. Added note about this
443 usage in dump's man page.

4452. Fixed a problem in restore when reading tapes written on big
446 endian machines with very old versions of dump. The patch was
447 contributed by George Helffrich <george@geology.bristol.ac.uk>.

4534. Added a new set of examples in dump_on_cd_2 directory, based
454 on dump_on_cd examples but somewhat enhanced, supporting DVD
455 media, and localized in english and german. Thanks to
456 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

4585. Made dump save 32 bit UID/GID. Internally, this was achieved
459 by switching from the old BSD inode format to the new BSD
460 inode format, which means that the tape format was changed.
461 However, since all restore versions out there should
462 transparently support both inode formats, the change should
463 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
464 reporting the bug.

4748. Rewrote entirely the man pages using the tmac.an macro
475 package (Linux man page format) instead of the original BSD
476 format. They should be now cleaner and easier to modify.

4811. Fixed a problem in the rmt ioctl command, where ioctl's issued from
482 non Linux clients were misinterpreted. The description of the problem
483 (incompatible numbering in Linux mtio opcodes) is documented at
484 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
