3Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
4====================================================================
e0267986
SP
5
61. Fixed dump compilation with old gcc versions. Thanks to
7 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 8
75654eee
SP
92. Fixed some warnings (howmany, roundup, powerof2 redefined)
10 when compiling against a recent glibc version.
11
43e6ea49
SP
123. Fixed a bug in restore preventing the read of a dump tape
13 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
14 <phiggins@transzap.com> for reporting the bug and providing
15 the test case.
16
d435f57f
SP
174. Changed dump to enable the creation of volumes of different
18 sizes in a single run (make -B accept a list of values).
19 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
20
e1ba02ef
SP
215. Use the glibc provided minor() and major() macros instead
22 of our own bitmask implementation. This should be safe for
23 when the major/minor namespace will migrate to 32 bits.
24 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
25 the bug.
26
ae6919a7
SP
276. Made explicit in the dump man page that dump will not create
28 a remote file, it will only write to an already existing one.
29
4acaf865
SP
307. Another try at making size estimates better again.
31
956756f2
SP
328. Put back the inconditional running of the end-of-tape
33 script which was changed in 0.434 to be run only when -M
34 or multiple -f were NOT specified. Some users rely on this
35 feature even when it is combined with -M/-f.
36
e4e31ce9
SP
379. Fixed restore when restoring huge backups (where rstdir...
38 temporary files are over 2GB). Thanks to
39 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
40 debugging the issue and making the patch.
41
cc7747eb
SP
4210. Made restore understand FreeBSD UFS2 tapes. Thanks to
43 David <vrtin@users.sourceforge.net> for submitting the bug
44 and providing a test case.
45
28ba5cae
SP
4611. Made dump work with an arbitrary integer level (no more 10
47 levels only limitation). Thanks to Matthew
48 <msvincen@midway.uchicago.edu> for the patch.
49
dcac75e9
SP
50Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
51=======================================================================
8ad151aa
SP
52
531. Added a note in the dump man page saying that the default
54 blocksize can be 32 if -d is used with a high density argument.
55 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
56 for the patch.
ed194aec 57
008af419
SP
582. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
59 LDFLAGS environment variables. Thanks to Arcady Genkin
60 <antipode@users.sourceforge.net> for reporting the bug.
61
0d4dfd07 623. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
63 to be excluded, rather than a hardcoded maximum. Thanks to
64 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
65
0d4dfd07
SP
664. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
67 and -D_USE_BSD_SIGNAL defines in configure in order to solve
68 64bit build problems because quad_t is redifined with a
69 different signature. Thanks to Mike Harris <mharris@redhat.com>
70 for reporting this bug.
71
5d8d264f 725. Made restore build on Solaris, making possible to
d1925e0c
SP
73 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
74 <uwe@ugsoft.de> for the patch.
75
766. Made an extension in the dump tape format capable of saving
77 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
78 wrote the extension and contributed the restore code back
79 into this codebase. The same extension mechanism will be
80 used in the future to save ACLs...
81
827. Made rmt work correctly with regard to QFA and local/remote
83 files and tapes. The remote access will however work only
84 when the dump provided rmt version is used. If you want to
85 use another rmt server, please do not use the QFA feature.
5d8d264f 86 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.

SP
88Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
89====================================================================
ed194aec
SP
90
911. Fixed the INSTALL file to reflect the actual install paths.
92 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
93 reporting the bug.
4bb009da 94
d3e542e7
SP
952. Fixed the configure script to only check for headers presence
96 instead of trying to compile them. This should fix issues
97 with old build environments. Thanks to Kari Lempiainen
98 <kari@funky.pp.fi> for reporting the bug.
99
1176b3c1
SP
1003. Fixed restore to correctly ignore sockets when comparing
101 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
102 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
103
1044. Fixed restore to correctly access the archive file (-A argument)
105 even when using a remote tape. Thanks to Fabrice Bellet
106 <fabrice@bellet.info> for reporting the bug.
1176b3c1 107
900bffdb
SP
1085. Fixed (again) handling of long (largefile) seeks in rmt.
109 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
110 the bug.
111
6d834d25
SP
1126. Fixed restore corner case when dealing with large block sizes
113 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
114 <fabrice@bellet.info> for reporting the bug.
115
cdef84ca
SP
1167. Fixed a bug preventing dump to access a filesystem having
117 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
118 for reporting the bug.
119
3458b64d
SP
1208. Made dump store dump dates using explicit timezones, fixing a
121 problem with incremental dumps if the timezone is modified
122 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
123 the bug report and the patch.
124
2be77799
SP
1259. Fixed a bug encountered when dumping individual files (not full
126 filesystems or directories) and dangling symbolic links happen
127 to be in the list of files. For as far as dump is concerned,
128 dangling symbolic links are allowed, and are dumped as is.
129 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
130 bug and providing the fix.
131
c3f69f06
SP
13210. Fixed open and creation modes and permissions for QFA and
133 table-of-contents files in dump and restore. Thanks to
134 Philippe Troin <phil@fifi.org> for the patch.
135
13611. Fixed the archive file descriptor handling enabling it to be 0.
137 This can happen in some cases when shell redirections are used.
138 Thanks to Philippe Troin <phil@fifi.org> for the patch.
139
14012. Delayed the opening of archive file until after suid had been
141 dropped (fixing a possible security issue if dump is suid).
142 Thanks to Philippe Troin <phil@fifi.org> for the patch.
143
14413. Fixed the 'S' command handling in the rmt client part.
145 Thanks to Philippe Troin <phil@fifi.org> for the patch.
146
14714. Modified the end-of-tape script handling to print out statistics
148 (and stop the timer) before launching the eot script. Also, the eot
149 script does not get run anymore when using -M (which makes sense) or
150 when multiple tapes are listed on the command line
151 (-f tape0,tape1,tapen) (which also makes sense).
152 Thanks to Philippe Troin <phil@fifi.org> for the patch.
153
e1abc9ce
SP
15415. Relicensed dump/restore under the 'revised' BSD license, as per
155 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
156
206f768c
SP
15716. Added LZO compression to dump. This new compression method has
158 the advantage of being super fast, thus not killing tape streaming
159 on slow machines. Thanks to Helmut Jarausch
160 <jarausch@igpm.rwth-aachen.de> for the patch and to
161 Markus Oberhumer <markus@oberhumer.com> for giving special permission
162 to include his miniLZO project (GPL licensed) in dump/restore.
163
e2392789
SP
16417. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
165 <ant@notatla.demon.co.uk> for reporting the bugs.
166
cdfe1392
SP
16718. Added a special rmt version which can do encryption when writing
168 to tape. Read examples/encrypted_rmt/README for details on
169 how to enable and configure it. Thanks to Ken Lalonde
170 <ken@globalremit.com> for the patch.
171
61e9d4ff
SP
17219. Made dump work with 2.5 kernel end of tape early warning semantics.
173 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
174
8c95cc30
SP
17520. Fixed a bug which caused dump -w|-W not to work anymore, because
176 the fs_freq and fs_passno fields in /etc/mtab are always set
177 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
178 reporting the bug.
179
cbdba727 180Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
181=======================================================================
182
1831. Added a note in the restore man page clarifying the question
184 'set the permissions on the current directory ?' asked by
185 restore at the end of treatment in -i and -x modes.
d86089d1 186
c898ca7a
SP
1872. Fixed the endianess issues when reading compressed tapes.
188 Thanks to Dark Force <daq4th@users.sourceforge.net> for
189 reporting this bug and providing test cases.
190
a028bdc8
SP
1913. Fixed the "ACL won't be dumped" warning message (which showed
192 an extra, unrelated error message). Thanks to Dragan Krnic
193 <dkrnic@lycos.com> for reporting this bug.
194
a8a6a503 1954. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
196 when searching for filesystem paths. Also fixed some problems
197 caused by binding mounts or multiple block device mounts.
198 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
199 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
200 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
201 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 202
3211c85b
SP
2035. Made dump's -I option accept the value '0' meaning all the
204 read errors will be ignored. This can be useful when running
205 dump from unattended sessions (like cron jobs). Thanks to
206 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
207
7fcd6df5
SP
2086. Fixed the output of dump to indicate 'blocks' instead of
209 'tape blocks' in the various messages (blocks are always
210 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
211 made it clearly print the current blocksize at the start of
212 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
213 the suggestions.
214
5bf65105
SP
2157. Made rmt understand long (largefiles) seeks.
216
dbb649e8
SP
2178. Fixed build with very old versions of libext2fs, where
218 EXT2_FT_* constants were undefined.
219
c92d83ae
SP
2209. Made dump accept the dumpdates path on the command line
221 (-D file option) instead of using only the hardcoded one.
222 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
223 suggestion.
224
1daf06b9
SP
22510. Enabled rmt, LFS, readline, QFA options by default in
226 ./configure. Updated the configure process (new versions
227 of config.guess, config.sub etc).
228
51c11d00
SP
229Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
230=======================================================================
d86089d1
SP
231
2321. Changed dump to use fcntl(F_SETLK) style locking instead
233 of flock() when locking the dumpdates file. With the old
234 locking scheme, a local user having read rights on the
235 dumpdates file could be able to do a Denial of Service attack
236 on dump. In order to lock the dumpdates file with the new
237 scheme, the user would need to have write access on the file.
238 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
239 reporting the bug (originally a bugtraq post).
ba3af39e 240
2f562f4e
SP
2412. Fixed interactive 'ls' which caused spurious errors warnings
242 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
243 <jorgen_ostling@users.sourceforge.net> for reporting this
244 bug.
245
1c736b78
SP
2463. Fixed dump's estimate when dealing with sparse inodes.
247
876861d2
SP
2484. Modified dump to allow setting a blocksize bigger than 32kB
249 (raised the limit to 1024kB), because newer hardware needs
250 this for proper operation. Thanks to Dirk Traenapp
251 <dtraenapp@users.sourceforge.net> for reporting this.
252
b8d848c9
SP
2535. Fixed a bug causing Dump to stop and report an error if an
254 inode number in the exclude file was followed by some amount
255 of whitespace. Thanks to Jeffrey Sofferin
256 <sofferin@users.sourceforge.net> for reporting this bug.
257
e531c442
SP
2586. Fixed a bug which caused restore, in some particular cases,
259 to ask some 'scary' questions and leave a bunch of RSTTMP
260 directories behind when restoring incremental tapes. Thanks
261 to Philippe Troin <phil@fifi.org> for reporting this bug and
262 providing the test cases.
263
c993d83a
SP
2647. Changed the wording when inodes are excluded from dump:
265 replaced 'Added inode 7 to exclude list' with
266 'Excluding inode 7 (resize inode) from dump', as suggested
267 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
268
cbc7fd6a 269Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
270===================================================================
271
2721. Fixed rmt open flags transmission (GNU's symbolic syntax over
273 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
274 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 275
4095abc0
SP
276Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
277===================================================================
aa1b1e7f
SP
278
2791. Made dump print out the ext2 logical block number in case of a read
280 error, which can be given as an argument to debugfs' ncheck command,
281 in order to find out the affected inode. Added note about this
282 usage in dump's man page.
ed7c25a3
SP
283
2842. Fixed a problem in restore when reading tapes written on big
285 endian machines with very old versions of dump. The patch was
286 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
287
2883. Fixed the tape length calculation when using large tapes
289 and compression. Thanks to Georg Lippold
290 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
291
2924. Added a new set of examples in dump_on_cd_2 directory, based
293 on dump_on_cd examples but somewhat enhanced, supporting DVD
294 media, and localized in english and german. Thanks to
295 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
296
9ca70cf6
SP
2975. Made dump save 32 bit UID/GID. Internally, this was achieved
298 by switching from the old BSD inode format to the new BSD
299 inode format, which means that the tape format was changed.
300 However, since all restore versions out there should
301 transparently support both inode formats, the change should
302 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
303 reporting the bug.
a18d5997
SP
304
3056. Fixed a lot of warnings in the code shown when compiling
306 with 'gcc -W'. Thanks to Matthias Andree
307 <matthias.andree@stud.uni-dortmund.de> for reporting this.
308
2a2e321d
SP
3097. Fixed a small markup bug in the dump man page. Thanks to
310 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
311 patch.
312
153f9a83
SP
3138. Rewrote entirely the man pages using the tmac.an macro
314 package (Linux man page format) instead of the original BSD
315 format. They should be now cleaner and easier to modify.
316
cf88ef4c
SP
317Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
318==================================================================
d24dc8af
SP
319
3201. Fixed a problem in the rmt ioctl command, where ioctl's issued from
321 non Linux clients were misinterpreted. The description of the problem
322 (incompatible numbering in Linux mtio opcodes) is documented at
323 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
324
