3Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
4==================================================================
d7783603
SP
5
61. Added the --enable-staticz configure option which enables
7 dump and restore to be linked with static versions of
8 libz and libbz2 (and dynamic versions of all other libraries).
9 This will make Debian users happy, because libz and libbz2
10 were the only needed libraries living in /usr, all the
11 others live in /lib. In case of system emergency, it is
12 better not to have to rely on an extra filesystem.
13 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 14
b3f55532
SP
152. Fix compilation on (at least the Linux Debian port to) AMD64.
16 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
17 that are also defined by <linux/types.h> (<asm/types.h>) and
18 they conflict).
19
1f2c193e
SP
203. Make dump's reading of the dumpdates file a bit more robust,
21 preventing dump from crashing when the dumpdates file has
22 been modified by hand.
23
e1e4be20
SP
244. Fixed some offset calculations in dump code which could
25 lead to "bread lseek errors" on large filesystems. Thanks
26 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
27 reporting this bug and debugging the issue.
28
c9e4e868
SP
295. Made dump use the blkid library when searching for devices
30 by label or uuid instead of dump's own routines.
31
97be3358
SP
326. Corrected a bug in dump where a wrong LABEL=... line in
33 /etc/fstab could prevent dump from dumping unrelated
34 filesystems. Thanks to Bruce Lowekamp
35 <lowekamp@users.sourceforge.net> for reporting the bug.
36

SP
37Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
38====================================================================
e0267986
SP
39
401. Fixed dump compilation with old gcc versions. Thanks to
41 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 42
75654eee
SP
432. Fixed some warnings (howmany, roundup, powerof2 redefined)
44 when compiling against a recent glibc version.
45
43e6ea49
SP
463. Fixed a bug in restore preventing the read of a dump tape
47 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
48 <phiggins@transzap.com> for reporting the bug and providing
49 the test case.
50
d435f57f
SP
514. Changed dump to enable the creation of volumes of different
52 sizes in a single run (make -B accept a list of values).
53 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
54
e1ba02ef
SP
555. Use the glibc provided minor() and major() macros instead
56 of our own bitmask implementation. This should be safe for
57 when the major/minor namespace will migrate to 32 bits.
58 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
59 the bug.
60
ae6919a7
SP
616. Made explicit in the dump man page that dump will not create
62 a remote file, it will only write to an already existing one.
63
4acaf865
SP
647. Another try at making size estimates better again.
65
956756f2
SP
668. Put back the inconditional running of the end-of-tape
67 script which was changed in 0.434 to be run only when -M
68 or multiple -f were NOT specified. Some users rely on this
69 feature even when it is combined with -M/-f.
70
e4e31ce9
SP
719. Fixed restore when restoring huge backups (where rstdir...
72 temporary files are over 2GB). Thanks to
73 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
74 debugging the issue and making the patch.
75
cc7747eb
SP
7610. Made restore understand FreeBSD UFS2 tapes. Thanks to
77 David <vrtin@users.sourceforge.net> for submitting the bug
78 and providing a test case.
79
28ba5cae
SP
8011. Made dump work with an arbitrary integer level (no more 10
81 levels only limitation). Thanks to Matthew
82 <msvincen@midway.uchicago.edu> for the patch.
83
dcac75e9
SP
84Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
85=======================================================================
8ad151aa
SP
86
871. Added a note in the dump man page saying that the default
88 blocksize can be 32 if -d is used with a high density argument.
89 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
90 for the patch.
ed194aec 91
008af419
SP
922. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
93 LDFLAGS environment variables. Thanks to Arcady Genkin
94 <antipode@users.sourceforge.net> for reporting the bug.
95
0d4dfd07 963. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
97 to be excluded, rather than a hardcoded maximum. Thanks to
98 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
99
0d4dfd07
SP
1004. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
101 and -D_USE_BSD_SIGNAL defines in configure in order to solve
102 64bit build problems because quad_t is redifined with a
103 different signature. Thanks to Mike Harris <mharris@redhat.com>
104 for reporting this bug.
105
5d8d264f 1065. Made restore build on Solaris, making possible to
d1925e0c
SP
107 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
108 <uwe@ugsoft.de> for the patch.
109
1106. Made an extension in the dump tape format capable of saving
111 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
112 wrote the extension and contributed the restore code back
113 into this codebase. The same extension mechanism will be
114 used in the future to save ACLs...
115
1167. Made rmt work correctly with regard to QFA and local/remote
117 files and tapes. The remote access will however work only
118 when the dump provided rmt version is used. If you want to
119 use another rmt server, please do not use the QFA feature.
5d8d264f 120 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 121
b564cb84
SP
122Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
123====================================================================
ed194aec
SP
124
1251. Fixed the INSTALL file to reflect the actual install paths.
126 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
127 reporting the bug.
4bb009da 128
d3e542e7
SP
1292. Fixed the configure script to only check for headers presence
130 instead of trying to compile them. This should fix issues
131 with old build environments. Thanks to Kari Lempiainen
132 <kari@funky.pp.fi> for reporting the bug.
133
1176b3c1
SP
1343. Fixed restore to correctly ignore sockets when comparing
135 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
136 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
137
1384. Fixed restore to correctly access the archive file (-A argument)
139 even when using a remote tape. Thanks to Fabrice Bellet
140 <fabrice@bellet.info> for reporting the bug.
1176b3c1 141
900bffdb
SP
1425. Fixed (again) handling of long (largefile) seeks in rmt.
143 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
144 the bug.
145
6d834d25
SP
1466. Fixed restore corner case when dealing with large block sizes
147 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
148 <fabrice@bellet.info> for reporting the bug.
149
cdef84ca
SP
1507. Fixed a bug preventing dump to access a filesystem having
151 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
152 for reporting the bug.
153
3458b64d
SP
1548. Made dump store dump dates using explicit timezones, fixing a
155 problem with incremental dumps if the timezone is modified
156 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
157 the bug report and the patch.
158
2be77799
SP
1599. Fixed a bug encountered when dumping individual files (not full
160 filesystems or directories) and dangling symbolic links happen
161 to be in the list of files. For as far as dump is concerned,
162 dangling symbolic links are allowed, and are dumped as is.
163 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
164 bug and providing the fix.
165
c3f69f06
SP
16610. Fixed open and creation modes and permissions for QFA and
167 table-of-contents files in dump and restore. Thanks to
168 Philippe Troin <phil@fifi.org> for the patch.
169
17011. Fixed the archive file descriptor handling enabling it to be 0.
171 This can happen in some cases when shell redirections are used.
172 Thanks to Philippe Troin <phil@fifi.org> for the patch.
173
17412. Delayed the opening of archive file until after suid had been
175 dropped (fixing a possible security issue if dump is suid).
176 Thanks to Philippe Troin <phil@fifi.org> for the patch.
177
17813. Fixed the 'S' command handling in the rmt client part.
179 Thanks to Philippe Troin <phil@fifi.org> for the patch.
180
18114. Modified the end-of-tape script handling to print out statistics
182 (and stop the timer) before launching the eot script. Also, the eot
183 script does not get run anymore when using -M (which makes sense) or
184 when multiple tapes are listed on the command line
185 (-f tape0,tape1,tapen) (which also makes sense).
186 Thanks to Philippe Troin <phil@fifi.org> for the patch.
187
e1abc9ce
SP
18815. Relicensed dump/restore under the 'revised' BSD license, as per
189 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
190
206f768c
SP
19116. Added LZO compression to dump. This new compression method has
192 the advantage of being super fast, thus not killing tape streaming
193 on slow machines. Thanks to Helmut Jarausch
194 <jarausch@igpm.rwth-aachen.de> for the patch and to
195 Markus Oberhumer <markus@oberhumer.com> for giving special permission
196 to include his miniLZO project (GPL licensed) in dump/restore.
197
e2392789
SP
19817. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
199 <ant@notatla.demon.co.uk> for reporting the bugs.
200
cdfe1392
SP
20118. Added a special rmt version which can do encryption when writing
202 to tape. Read examples/encrypted_rmt/README for details on
203 how to enable and configure it. Thanks to Ken Lalonde
204 <ken@globalremit.com> for the patch.
205
61e9d4ff
SP
20619. Made dump work with 2.5 kernel end of tape early warning semantics.
207 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
208
8c95cc30
SP
20920. Fixed a bug which caused dump -w|-W not to work anymore, because
210 the fs_freq and fs_passno fields in /etc/mtab are always set
211 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
212 reporting the bug.
213
cbdba727 214Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
215=======================================================================
216
2171. Added a note in the restore man page clarifying the question
218 'set the permissions on the current directory ?' asked by
219 restore at the end of treatment in -i and -x modes.
d86089d1 220
c898ca7a
SP
2212. Fixed the endianess issues when reading compressed tapes.
222 Thanks to Dark Force <daq4th@users.sourceforge.net> for
223 reporting this bug and providing test cases.
224
a028bdc8
SP
2253. Fixed the "ACL won't be dumped" warning message (which showed
226 an extra, unrelated error message). Thanks to Dragan Krnic
227 <dkrnic@lycos.com> for reporting this bug.
228
a8a6a503 2294. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
230 when searching for filesystem paths. Also fixed some problems
231 caused by binding mounts or multiple block device mounts.
232 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
233 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
234 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
235 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 236
3211c85b
SP
2375. Made dump's -I option accept the value '0' meaning all the
238 read errors will be ignored. This can be useful when running
239 dump from unattended sessions (like cron jobs). Thanks to
240 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
241
7fcd6df5
SP
2426. Fixed the output of dump to indicate 'blocks' instead of
243 'tape blocks' in the various messages (blocks are always
244 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
245 made it clearly print the current blocksize at the start of
246 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
247 the suggestions.
248
5bf65105
SP
2497. Made rmt understand long (largefiles) seeks.
250
dbb649e8
SP
2518. Fixed build with very old versions of libext2fs, where
252 EXT2_FT_* constants were undefined.
253
c92d83ae
SP
2549. Made dump accept the dumpdates path on the command line
255 (-D file option) instead of using only the hardcoded one.
256 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
257 suggestion.
258
1daf06b9
SP
25910. Enabled rmt, LFS, readline, QFA options by default in
260 ./configure. Updated the configure process (new versions
261 of config.guess, config.sub etc).
262
51c11d00
SP
263Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
264=======================================================================
d86089d1
SP
265
2661. Changed dump to use fcntl(F_SETLK) style locking instead
267 of flock() when locking the dumpdates file. With the old
268 locking scheme, a local user having read rights on the
269 dumpdates file could be able to do a Denial of Service attack
270 on dump. In order to lock the dumpdates file with the new
271 scheme, the user would need to have write access on the file.
272 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
273 reporting the bug (originally a bugtraq post).
ba3af39e 274
2f562f4e
SP
2752. Fixed interactive 'ls' which caused spurious errors warnings
276 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
277 <jorgen_ostling@users.sourceforge.net> for reporting this
278 bug.
279
1c736b78
SP
2803. Fixed dump's estimate when dealing with sparse inodes.
281
876861d2
SP
2824. Modified dump to allow setting a blocksize bigger than 32kB
283 (raised the limit to 1024kB), because newer hardware needs
284 this for proper operation. Thanks to Dirk Traenapp
285 <dtraenapp@users.sourceforge.net> for reporting this.
286
b8d848c9
SP
2875. Fixed a bug causing Dump to stop and report an error if an
288 inode number in the exclude file was followed by some amount
289 of whitespace. Thanks to Jeffrey Sofferin
290 <sofferin@users.sourceforge.net> for reporting this bug.
291
e531c442
SP
2926. Fixed a bug which caused restore, in some particular cases,
293 to ask some 'scary' questions and leave a bunch of RSTTMP
294 directories behind when restoring incremental tapes. Thanks
295 to Philippe Troin <phil@fifi.org> for reporting this bug and
296 providing the test cases.
297
c993d83a
SP
2987. Changed the wording when inodes are excluded from dump:
299 replaced 'Added inode 7 to exclude list' with
300 'Excluding inode 7 (resize inode) from dump', as suggested
301 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
302
cbc7fd6a 303Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
304===================================================================
305
3061. Fixed rmt open flags transmission (GNU's symbolic syntax over
307 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
308 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 309
4095abc0
SP
310Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
311===================================================================
aa1b1e7f
SP
312
3131. Made dump print out the ext2 logical block number in case of a read
314 error, which can be given as an argument to debugfs' ncheck command,
315 in order to find out the affected inode. Added note about this
316 usage in dump's man page.
ed7c25a3
SP
317
3182. Fixed a problem in restore when reading tapes written on big
319 endian machines with very old versions of dump. The patch was
320 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
321
3223. Fixed the tape length calculation when using large tapes
323 and compression. Thanks to Georg Lippold
324 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
325
3264. Added a new set of examples in dump_on_cd_2 directory, based
327 on dump_on_cd examples but somewhat enhanced, supporting DVD
328 media, and localized in english and german. Thanks to
329 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
330
9ca70cf6
SP
3315. Made dump save 32 bit UID/GID. Internally, this was achieved
332 by switching from the old BSD inode format to the new BSD
333 inode format, which means that the tape format was changed.
334 However, since all restore versions out there should
335 transparently support both inode formats, the change should
336 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
337 reporting the bug.
a18d5997
SP
338
3396. Fixed a lot of warnings in the code shown when compiling
340 with 'gcc -W'. Thanks to Matthias Andree
341 <matthias.andree@stud.uni-dortmund.de> for reporting this.
342
2a2e321d
SP
3437. Fixed a small markup bug in the dump man page. Thanks to
344 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
345 patch.
346
153f9a83
SP
3478. Rewrote entirely the man pages using the tmac.an macro
348 package (Linux man page format) instead of the original BSD
349 format. They should be now cleaner and easier to modify.
350
cf88ef4c
SP
351Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
352==================================================================
d24dc8af
SP
353
3541. Fixed a problem in the rmt ioctl command, where ioctl's issued from
355 non Linux clients were misinterpreted. The description of the problem
356 (incompatible numbering in Linux mtio opcodes) is documented at
357 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
358
