SP
3Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
4=================================================================
f30c53e5
SP
5
61. Changed restore to emit warnings (instead of emitting a fatal
7 error) if a file (or a directory) is unavailable for a
8 comparision (if the user doesn't have the necessary permissions
9 to access it for example). Thanks to Kenneth Porter
10 <shiva@sewingwitch.com> for the bug report.
35ed8cf8 11
979da669
SP
122. Re-done the 'do not save directory entries to non-dumped inodes
13 (excluded from dump)' feature. The previous implementation
14 worked well for excluded directories but not for regular files.
15 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
16 report.
17
1ba0c4bb
SP
183. Fixed a bug in dump where the tape size was miscalculated when
19 the user used -d/-s to specify the tape characteristics. Thanks
20 to Philip Goisman <goisman@physics.arizona.edu> for reporting
21 the bug.
22
c21722b0
SP
234. Fixed another bug introduced in restore with the hashtree
24 implementation. This one caused restore to stop saying
25 "removenode: non-empty directory" in some cases.
26
cca7148b
SP
275. Added support for dumping and restoring ext2/3 extended
28 attributes (EA), like the access control lists (ACL) or
29 the security labels used by SELinux.
30
debbffbc
SP
31Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
32======================================================================
35ed8cf8
SP
33
341. The newly added dump_on_cd_3 example was buggy, replace it
35 with an updated version from Andrew Basterfield
36 <bob@cemetery.homeunix.org>.
b79d20f1 37
30e8407d
SP
382. Made restore to chdir() back into the initial directory when
39 dumping core while aborting a comparision operation. The
40 previous behaviour was to write the corefile at the root of
41 the directory being compared, which could very well be
42 read only and preventing the corefile generation. Thanks
43 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
44
b43981b3
SP
453. Silenced the failure to call fgetflags() when comparing an
46 entry which has no ext2 attributes (as in lsattr()).
47
68415469
SP
484. Fix a brown paper bug in restore -C which broke restore and
49 caused modifications on the filesystem being compared
50 (directories containing a file with the same name as the
51 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
52 <shiva@sewingwitch.com> for finding the bug and helping me
53 reproduce it.
54
18dc6e86
SP
555. Made restore -C force the -N flag (no writing allowed on
56 the disk) in order to prevent more bugs like the above one.
57
cdd136ec
SP
58Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
59=====================================================================
b79d20f1
SP
60
611. Fix a couple of troff syntax bugs in the man pages.
62 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 63
0556ca22
SP
642. Made restore use either libncurses or libtermcap, depending
65 on which one is available at configure time.
66
7d422735
SP
673. Fixed restore negative size display bug when comparing a
68 dump containing files over 2GB. Thanks to Steve Bonds
69 <sbonds@users.sourceforge.net> for the bug report.
70
585ca01a
SP
714. Do not save directory entries to non-dumped inodes
72 (excluded from dump). This will eliminate the 'missing
73 file' warnings when doing 'restore -C'.
74
241ddca3
SP
755. Fix dump crash when backuping a huge (2TB) filesystem,
76 due to a bogus calculation on the inode map size.
77 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
78 submitting the bug and testing the fix.
79
47acd076
SP
806. Fix a problem in restore where the final \0 in the symbolic
81 link names could have been lost, generating corrupt filenames.
82 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
83 bug.
84
741eb204
SP
857. Implemented a hash list for the directory names in restore.
86 The linear list used before caused problems in interactive
87 restores when dealing with directories having thousands of
88 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
89 for reporting the bug.
90
a55ce914
SP
918. Improved restore -C, this time including the directory
92 attributes into the comparision.
93
949. Made restore understand tapes containing EA/ACLs (which will
95 be dumped by the next version of dump). In this version
96 extended attributes on the tape are ignored, for full EA/ACL
97 support wait for the next version or try the experimental EA
98 patch.
99
498a402f
SP
100Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
101==================================================================
d7783603
SP
102
1031. Added the --enable-staticz configure option which enables
104 dump and restore to be linked with static versions of
105 libz and libbz2 (and dynamic versions of all other libraries).
106 This will make Debian users happy, because libz and libbz2
107 were the only needed libraries living in /usr, all the
108 others live in /lib. In case of system emergency, it is
109 better not to have to rely on an extra filesystem.
110 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 111
b3f55532
SP
1122. Fix compilation on (at least the Linux Debian port to) AMD64.
113 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
114 that are also defined by <linux/types.h> (<asm/types.h>) and
115 they conflict).
116
1f2c193e
SP
1173. Make dump's reading of the dumpdates file a bit more robust,
118 preventing dump from crashing when the dumpdates file has
119 been modified by hand.
120
e1e4be20
SP
1214. Fixed some offset calculations in dump code which could
122 lead to "bread lseek errors" on large filesystems. Thanks
123 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
124 reporting this bug and debugging the issue.
125
c9e4e868
SP
1265. Made dump use the blkid library when searching for devices
127 by label or uuid instead of dump's own routines.
128
97be3358
SP
1296. Corrected a bug in dump where a wrong LABEL=... line in
130 /etc/fstab could prevent dump from dumping unrelated
131 filesystems. Thanks to Bruce Lowekamp
132 <lowekamp@users.sourceforge.net> for reporting the bug.
133
ddf54486
SP
134Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
135====================================================================
e0267986
SP
136
1371. Fixed dump compilation with old gcc versions. Thanks to
138 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 139
75654eee
SP
1402. Fixed some warnings (howmany, roundup, powerof2 redefined)
141 when compiling against a recent glibc version.
142
43e6ea49
SP
1433. Fixed a bug in restore preventing the read of a dump tape
144 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
145 <phiggins@transzap.com> for reporting the bug and providing
146 the test case.
147
d435f57f
SP
1484. Changed dump to enable the creation of volumes of different
149 sizes in a single run (make -B accept a list of values).
150 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
151
e1ba02ef
SP
1525. Use the glibc provided minor() and major() macros instead
153 of our own bitmask implementation. This should be safe for
154 when the major/minor namespace will migrate to 32 bits.
155 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
156 the bug.
157
ae6919a7
SP
1586. Made explicit in the dump man page that dump will not create
159 a remote file, it will only write to an already existing one.
160
4acaf865
SP
1617. Another try at making size estimates better again.
162
956756f2
SP
1638. Put back the inconditional running of the end-of-tape
164 script which was changed in 0.434 to be run only when -M
165 or multiple -f were NOT specified. Some users rely on this
166 feature even when it is combined with -M/-f.
167
e4e31ce9
SP
1689. Fixed restore when restoring huge backups (where rstdir...
169 temporary files are over 2GB). Thanks to
170 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
171 debugging the issue and making the patch.
172
cc7747eb
SP
17310. Made restore understand FreeBSD UFS2 tapes. Thanks to
174 David <vrtin@users.sourceforge.net> for submitting the bug
175 and providing a test case.
176
28ba5cae
SP
17711. Made dump work with an arbitrary integer level (no more 10
178 levels only limitation). Thanks to Matthew
179 <msvincen@midway.uchicago.edu> for the patch.
180
dcac75e9
SP
181Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
182=======================================================================
8ad151aa
SP
183
1841. Added a note in the dump man page saying that the default
185 blocksize can be 32 if -d is used with a high density argument.
186 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
187 for the patch.
ed194aec 188
008af419
SP
1892. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
190 LDFLAGS environment variables. Thanks to Arcady Genkin
191 <antipode@users.sourceforge.net> for reporting the bug.
192
0d4dfd07 1933. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
194 to be excluded, rather than a hardcoded maximum. Thanks to
195 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
196
0d4dfd07
SP
1974. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
198 and -D_USE_BSD_SIGNAL defines in configure in order to solve
199 64bit build problems because quad_t is redifined with a
200 different signature. Thanks to Mike Harris <mharris@redhat.com>
201 for reporting this bug.
202
5d8d264f 2035. Made restore build on Solaris, making possible to
d1925e0c
SP
204 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
205 <uwe@ugsoft.de> for the patch.
206
2076. Made an extension in the dump tape format capable of saving
208 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
209 wrote the extension and contributed the restore code back
210 into this codebase. The same extension mechanism will be
211 used in the future to save ACLs...
212
2137. Made rmt work correctly with regard to QFA and local/remote
214 files and tapes. The remote access will however work only
215 when the dump provided rmt version is used. If you want to
216 use another rmt server, please do not use the QFA feature.
5d8d264f 217 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 218

SP
219Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
220====================================================================
ed194aec
SP
221
2221. Fixed the INSTALL file to reflect the actual install paths.
223 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
224 reporting the bug.
4bb009da 225
d3e542e7
SP
2262. Fixed the configure script to only check for headers presence
227 instead of trying to compile them. This should fix issues
228 with old build environments. Thanks to Kari Lempiainen
229 <kari@funky.pp.fi> for reporting the bug.
230
1176b3c1
SP
2313. Fixed restore to correctly ignore sockets when comparing
232 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
233 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
234
2354. Fixed restore to correctly access the archive file (-A argument)
236 even when using a remote tape. Thanks to Fabrice Bellet
237 <fabrice@bellet.info> for reporting the bug.
1176b3c1 238
900bffdb
SP
2395. Fixed (again) handling of long (largefile) seeks in rmt.
240 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
241 the bug.
242
6d834d25
SP
2436. Fixed restore corner case when dealing with large block sizes
244 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
245 <fabrice@bellet.info> for reporting the bug.
246
cdef84ca
SP
2477. Fixed a bug preventing dump to access a filesystem having
248 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
249 for reporting the bug.
250
3458b64d
SP
2518. Made dump store dump dates using explicit timezones, fixing a
252 problem with incremental dumps if the timezone is modified
253 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
254 the bug report and the patch.
255
2be77799
SP
2569. Fixed a bug encountered when dumping individual files (not full
257 filesystems or directories) and dangling symbolic links happen
258 to be in the list of files. For as far as dump is concerned,
259 dangling symbolic links are allowed, and are dumped as is.
260 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
261 bug and providing the fix.
262
c3f69f06
SP
26310. Fixed open and creation modes and permissions for QFA and
264 table-of-contents files in dump and restore. Thanks to
265 Philippe Troin <phil@fifi.org> for the patch.
266
26711. Fixed the archive file descriptor handling enabling it to be 0.
268 This can happen in some cases when shell redirections are used.
269 Thanks to Philippe Troin <phil@fifi.org> for the patch.
270
27112. Delayed the opening of archive file until after suid had been
272 dropped (fixing a possible security issue if dump is suid).
273 Thanks to Philippe Troin <phil@fifi.org> for the patch.
274
27513. Fixed the 'S' command handling in the rmt client part.
276 Thanks to Philippe Troin <phil@fifi.org> for the patch.
277
27814. Modified the end-of-tape script handling to print out statistics
279 (and stop the timer) before launching the eot script. Also, the eot
280 script does not get run anymore when using -M (which makes sense) or
281 when multiple tapes are listed on the command line
282 (-f tape0,tape1,tapen) (which also makes sense).
283 Thanks to Philippe Troin <phil@fifi.org> for the patch.
284
e1abc9ce
SP
28515. Relicensed dump/restore under the 'revised' BSD license, as per
286 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
287
206f768c
SP
28816. Added LZO compression to dump. This new compression method has
289 the advantage of being super fast, thus not killing tape streaming
290 on slow machines. Thanks to Helmut Jarausch
291 <jarausch@igpm.rwth-aachen.de> for the patch and to
292 Markus Oberhumer <markus@oberhumer.com> for giving special permission
293 to include his miniLZO project (GPL licensed) in dump/restore.
294
e2392789
SP
29517. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
296 <ant@notatla.demon.co.uk> for reporting the bugs.
297
cdfe1392
SP
29818. Added a special rmt version which can do encryption when writing
299 to tape. Read examples/encrypted_rmt/README for details on
300 how to enable and configure it. Thanks to Ken Lalonde
301 <ken@globalremit.com> for the patch.
302
61e9d4ff
SP
30319. Made dump work with 2.5 kernel end of tape early warning semantics.
304 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
305
8c95cc30
SP
30620. Fixed a bug which caused dump -w|-W not to work anymore, because
307 the fs_freq and fs_passno fields in /etc/mtab are always set
308 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
309 reporting the bug.
310
cbdba727 311Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
312=======================================================================
313
3141. Added a note in the restore man page clarifying the question
315 'set the permissions on the current directory ?' asked by
316 restore at the end of treatment in -i and -x modes.
d86089d1 317
c898ca7a
SP
3182. Fixed the endianess issues when reading compressed tapes.
319 Thanks to Dark Force <daq4th@users.sourceforge.net> for
320 reporting this bug and providing test cases.
321
a028bdc8
SP
3223. Fixed the "ACL won't be dumped" warning message (which showed
323 an extra, unrelated error message). Thanks to Dragan Krnic
324 <dkrnic@lycos.com> for reporting this bug.
325
a8a6a503 3264. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
327 when searching for filesystem paths. Also fixed some problems
328 caused by binding mounts or multiple block device mounts.
329 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
330 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
331 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
332 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 333
3211c85b
SP
3345. Made dump's -I option accept the value '0' meaning all the
335 read errors will be ignored. This can be useful when running
336 dump from unattended sessions (like cron jobs). Thanks to
337 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
338
7fcd6df5
SP
3396. Fixed the output of dump to indicate 'blocks' instead of
340 'tape blocks' in the various messages (blocks are always
341 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
342 made it clearly print the current blocksize at the start of
343 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
344 the suggestions.
345
5bf65105
SP
3467. Made rmt understand long (largefiles) seeks.
347
dbb649e8
SP
3488. Fixed build with very old versions of libext2fs, where
349 EXT2_FT_* constants were undefined.
350
c92d83ae
SP
3519. Made dump accept the dumpdates path on the command line
352 (-D file option) instead of using only the hardcoded one.
353 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
354 suggestion.
355
1daf06b9
SP
35610. Enabled rmt, LFS, readline, QFA options by default in
357 ./configure. Updated the configure process (new versions
358 of config.guess, config.sub etc).
359
51c11d00
SP
360Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
361=======================================================================
d86089d1
SP
362
3631. Changed dump to use fcntl(F_SETLK) style locking instead
364 of flock() when locking the dumpdates file. With the old
365 locking scheme, a local user having read rights on the
366 dumpdates file could be able to do a Denial of Service attack
367 on dump. In order to lock the dumpdates file with the new
368 scheme, the user would need to have write access on the file.
369 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
370 reporting the bug (originally a bugtraq post).
ba3af39e 371
2f562f4e
SP
3722. Fixed interactive 'ls' which caused spurious errors warnings
373 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
374 <jorgen_ostling@users.sourceforge.net> for reporting this
375 bug.
376
1c736b78
SP
3773. Fixed dump's estimate when dealing with sparse inodes.
378
876861d2
SP
3794. Modified dump to allow setting a blocksize bigger than 32kB
380 (raised the limit to 1024kB), because newer hardware needs
381 this for proper operation. Thanks to Dirk Traenapp
382 <dtraenapp@users.sourceforge.net> for reporting this.
383
b8d848c9
SP
3845. Fixed a bug causing Dump to stop and report an error if an
385 inode number in the exclude file was followed by some amount
386 of whitespace. Thanks to Jeffrey Sofferin
387 <sofferin@users.sourceforge.net> for reporting this bug.
388
e531c442
SP
3896. Fixed a bug which caused restore, in some particular cases,
390 to ask some 'scary' questions and leave a bunch of RSTTMP
391 directories behind when restoring incremental tapes. Thanks
392 to Philippe Troin <phil@fifi.org> for reporting this bug and
393 providing the test cases.
394
c993d83a
SP
3957. Changed the wording when inodes are excluded from dump:
396 replaced 'Added inode 7 to exclude list' with
397 'Excluding inode 7 (resize inode) from dump', as suggested
398 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
399
cbc7fd6a 400Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
401===================================================================
402
4031. Fixed rmt open flags transmission (GNU's symbolic syntax over
404 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
405 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 406
4095abc0
SP
407Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
408===================================================================
aa1b1e7f
SP
409
4101. Made dump print out the ext2 logical block number in case of a read
411 error, which can be given as an argument to debugfs' ncheck command,
412 in order to find out the affected inode. Added note about this
413 usage in dump's man page.
ed7c25a3
SP
414
4152. Fixed a problem in restore when reading tapes written on big
416 endian machines with very old versions of dump. The patch was
417 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
418

4234. Added a new set of examples in dump_on_cd_2 directory, based
424 on dump_on_cd examples but somewhat enhanced, supporting DVD
425 media, and localized in english and german. Thanks to
426 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

4285. Made dump save 32 bit UID/GID. Internally, this was achieved
429 by switching from the old BSD inode format to the new BSD
430 inode format, which means that the tape format was changed.
431 However, since all restore versions out there should
432 transparently support both inode formats, the change should
433 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
434 reporting the bug.

4448. Rewrote entirely the man pages using the tmac.an macro
445 package (Linux man page format) instead of the original BSD
446 format. They should be now cleaner and easier to modify.

4511. Fixed a problem in the rmt ioctl command, where ioctl's issued from
452 non Linux clients were misinterpreted. The description of the problem
453 (incompatible numbering in Linux mtio opcodes) is documented at
454 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
