3Changes between versions 0.4b37 and 0.4b38 (released ????????????)
4==================================================================
5
61. Fix a couple of troff syntax bugs in the man pages.
7 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 8
0556ca22
SP
92. Made restore use either libncurses or libtermcap, depending
10 on which one is available at configure time.
11
7d422735
SP
123. Fixed restore negative size display bug when comparing a
13 dump containing files over 2GB. Thanks to Steve Bonds
14 <sbonds@users.sourceforge.net> for the bug report.
15
585ca01a
SP
164. Do not save directory entries to non-dumped inodes
17 (excluded from dump). This will eliminate the 'missing
18 file' warnings when doing 'restore -C'.

20Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
21==================================================================
d7783603
SP
22
231. Added the --enable-staticz configure option which enables
24 dump and restore to be linked with static versions of
25 libz and libbz2 (and dynamic versions of all other libraries).
26 This will make Debian users happy, because libz and libbz2
27 were the only needed libraries living in /usr, all the
28 others live in /lib. In case of system emergency, it is
29 better not to have to rely on an extra filesystem.
30 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 31
b3f55532
SP
322. Fix compilation on (at least the Linux Debian port to) AMD64.
33 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
34 that are also defined by <linux/types.h> (<asm/types.h>) and
35 they conflict).
36
1f2c193e
SP
373. Make dump's reading of the dumpdates file a bit more robust,
38 preventing dump from crashing when the dumpdates file has
39 been modified by hand.
40
e1e4be20
SP
414. Fixed some offset calculations in dump code which could
42 lead to "bread lseek errors" on large filesystems. Thanks
43 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
44 reporting this bug and debugging the issue.
45
c9e4e868
SP
465. Made dump use the blkid library when searching for devices
47 by label or uuid instead of dump's own routines.
48
97be3358
SP
496. Corrected a bug in dump where a wrong LABEL=... line in
50 /etc/fstab could prevent dump from dumping unrelated
51 filesystems. Thanks to Bruce Lowekamp
52 <lowekamp@users.sourceforge.net> for reporting the bug.

54Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
55====================================================================
e0267986
SP
56
571. Fixed dump compilation with old gcc versions. Thanks to
58 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 59
75654eee
SP
602. Fixed some warnings (howmany, roundup, powerof2 redefined)
61 when compiling against a recent glibc version.
62
43e6ea49
SP
633. Fixed a bug in restore preventing the read of a dump tape
64 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
65 <phiggins@transzap.com> for reporting the bug and providing
66 the test case.
67
d435f57f
SP
684. Changed dump to enable the creation of volumes of different
69 sizes in a single run (make -B accept a list of values).
70 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
71
e1ba02ef
SP
725. Use the glibc provided minor() and major() macros instead
73 of our own bitmask implementation. This should be safe for
74 when the major/minor namespace will migrate to 32 bits.
75 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
76 the bug.
77
ae6919a7
SP
786. Made explicit in the dump man page that dump will not create
79 a remote file, it will only write to an already existing one.
80
4acaf865
SP
817. Another try at making size estimates better again.
82
956756f2
SP
838. Put back the inconditional running of the end-of-tape
84 script which was changed in 0.434 to be run only when -M
85 or multiple -f were NOT specified. Some users rely on this
86 feature even when it is combined with -M/-f.
87
e4e31ce9
SP
889. Fixed restore when restoring huge backups (where rstdir...
89 temporary files are over 2GB). Thanks to
90 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
91 debugging the issue and making the patch.
92
cc7747eb
SP
9310. Made restore understand FreeBSD UFS2 tapes. Thanks to
94 David <vrtin@users.sourceforge.net> for submitting the bug
95 and providing a test case.
96
28ba5cae
SP
9711. Made dump work with an arbitrary integer level (no more 10
98 levels only limitation). Thanks to Matthew
99 <msvincen@midway.uchicago.edu> for the patch.
100
dcac75e9
SP
101Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
102=======================================================================
8ad151aa
SP
103
1041. Added a note in the dump man page saying that the default
105 blocksize can be 32 if -d is used with a high density argument.
106 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
107 for the patch.
ed194aec 108
008af419
SP
1092. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
110 LDFLAGS environment variables. Thanks to Arcady Genkin
111 <antipode@users.sourceforge.net> for reporting the bug.
112
0d4dfd07 1133. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
114 to be excluded, rather than a hardcoded maximum. Thanks to
115 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
116
0d4dfd07
SP
1174. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
118 and -D_USE_BSD_SIGNAL defines in configure in order to solve
119 64bit build problems because quad_t is redifined with a
120 different signature. Thanks to Mike Harris <mharris@redhat.com>
121 for reporting this bug.
122
5d8d264f 1235. Made restore build on Solaris, making possible to
d1925e0c
SP
124 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
125 <uwe@ugsoft.de> for the patch.
126
1276. Made an extension in the dump tape format capable of saving
128 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
129 wrote the extension and contributed the restore code back
130 into this codebase. The same extension mechanism will be
131 used in the future to save ACLs...
132
1337. Made rmt work correctly with regard to QFA and local/remote
134 files and tapes. The remote access will however work only
135 when the dump provided rmt version is used. If you want to
136 use another rmt server, please do not use the QFA feature.
5d8d264f 137 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.

140====================================================================
ed194aec
SP
141
1421. Fixed the INSTALL file to reflect the actual install paths.
143 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
144 reporting the bug.
4bb009da 145
d3e542e7
SP
1462. Fixed the configure script to only check for headers presence
147 instead of trying to compile them. This should fix issues
148 with old build environments. Thanks to Kari Lempiainen
149 <kari@funky.pp.fi> for reporting the bug.
150
1176b3c1
SP
1513. Fixed restore to correctly ignore sockets when comparing
152 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
153 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
154
1554. Fixed restore to correctly access the archive file (-A argument)
156 even when using a remote tape. Thanks to Fabrice Bellet
157 <fabrice@bellet.info> for reporting the bug.
1176b3c1 158
900bffdb
SP
1595. Fixed (again) handling of long (largefile) seeks in rmt.
160 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
161 the bug.
162
6d834d25
SP
1636. Fixed restore corner case when dealing with large block sizes
164 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
165 <fabrice@bellet.info> for reporting the bug.
166
cdef84ca
SP
1677. Fixed a bug preventing dump to access a filesystem having
168 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
169 for reporting the bug.
170
3458b64d
SP
1718. Made dump store dump dates using explicit timezones, fixing a
172 problem with incremental dumps if the timezone is modified
173 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
174 the bug report and the patch.
175
2be77799
SP
1769. Fixed a bug encountered when dumping individual files (not full
177 filesystems or directories) and dangling symbolic links happen
178 to be in the list of files. For as far as dump is concerned,
179 dangling symbolic links are allowed, and are dumped as is.
180 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
181 bug and providing the fix.
182
c3f69f06
SP
18310. Fixed open and creation modes and permissions for QFA and
184 table-of-contents files in dump and restore. Thanks to
185 Philippe Troin <phil@fifi.org> for the patch.
186
18711. Fixed the archive file descriptor handling enabling it to be 0.
188 This can happen in some cases when shell redirections are used.
189 Thanks to Philippe Troin <phil@fifi.org> for the patch.
190
19112. Delayed the opening of archive file until after suid had been
192 dropped (fixing a possible security issue if dump is suid).
193 Thanks to Philippe Troin <phil@fifi.org> for the patch.
194
19513. Fixed the 'S' command handling in the rmt client part.
196 Thanks to Philippe Troin <phil@fifi.org> for the patch.
197
19814. Modified the end-of-tape script handling to print out statistics
199 (and stop the timer) before launching the eot script. Also, the eot
200 script does not get run anymore when using -M (which makes sense) or
201 when multiple tapes are listed on the command line
202 (-f tape0,tape1,tapen) (which also makes sense).
203 Thanks to Philippe Troin <phil@fifi.org> for the patch.
204
e1abc9ce
SP
20515. Relicensed dump/restore under the 'revised' BSD license, as per
206 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
207
206f768c
SP
20816. Added LZO compression to dump. This new compression method has
209 the advantage of being super fast, thus not killing tape streaming
210 on slow machines. Thanks to Helmut Jarausch
211 <jarausch@igpm.rwth-aachen.de> for the patch and to
212 Markus Oberhumer <markus@oberhumer.com> for giving special permission
213 to include his miniLZO project (GPL licensed) in dump/restore.
214
e2392789
SP
21517. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
216 <ant@notatla.demon.co.uk> for reporting the bugs.
217
cdfe1392
SP
21818. Added a special rmt version which can do encryption when writing
219 to tape. Read examples/encrypted_rmt/README for details on
220 how to enable and configure it. Thanks to Ken Lalonde
221 <ken@globalremit.com> for the patch.
222
61e9d4ff
SP
22319. Made dump work with 2.5 kernel end of tape early warning semantics.
224 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
225
8c95cc30
SP
22620. Fixed a bug which caused dump -w|-W not to work anymore, because
227 the fs_freq and fs_passno fields in /etc/mtab are always set
228 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
229 reporting the bug.
230
cbdba727 231Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
232=======================================================================
233
2341. Added a note in the restore man page clarifying the question
235 'set the permissions on the current directory ?' asked by
236 restore at the end of treatment in -i and -x modes.
d86089d1 237
c898ca7a
SP
2382. Fixed the endianess issues when reading compressed tapes.
239 Thanks to Dark Force <daq4th@users.sourceforge.net> for
240 reporting this bug and providing test cases.
241
a028bdc8
SP
2423. Fixed the "ACL won't be dumped" warning message (which showed
243 an extra, unrelated error message). Thanks to Dragan Krnic
244 <dkrnic@lycos.com> for reporting this bug.
245
a8a6a503 2464. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
247 when searching for filesystem paths. Also fixed some problems
248 caused by binding mounts or multiple block device mounts.
249 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
250 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
251 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
252 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 253
3211c85b
SP
2545. Made dump's -I option accept the value '0' meaning all the
255 read errors will be ignored. This can be useful when running
256 dump from unattended sessions (like cron jobs). Thanks to
257 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
258
7fcd6df5
SP
2596. Fixed the output of dump to indicate 'blocks' instead of
260 'tape blocks' in the various messages (blocks are always
261 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
262 made it clearly print the current blocksize at the start of
263 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
264 the suggestions.
265
5bf65105
SP
2667. Made rmt understand long (largefiles) seeks.
267
dbb649e8
SP
2688. Fixed build with very old versions of libext2fs, where
269 EXT2_FT_* constants were undefined.
270
c92d83ae
SP
2719. Made dump accept the dumpdates path on the command line
272 (-D file option) instead of using only the hardcoded one.
273 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
274 suggestion.
275
1daf06b9
SP
27610. Enabled rmt, LFS, readline, QFA options by default in
277 ./configure. Updated the configure process (new versions
278 of config.guess, config.sub etc).
279
51c11d00
SP
280Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
281=======================================================================
d86089d1
SP
282
2831. Changed dump to use fcntl(F_SETLK) style locking instead
284 of flock() when locking the dumpdates file. With the old
285 locking scheme, a local user having read rights on the
286 dumpdates file could be able to do a Denial of Service attack
287 on dump. In order to lock the dumpdates file with the new
288 scheme, the user would need to have write access on the file.
289 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
290 reporting the bug (originally a bugtraq post).
ba3af39e 291
2f562f4e
SP
2922. Fixed interactive 'ls' which caused spurious errors warnings
293 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
294 <jorgen_ostling@users.sourceforge.net> for reporting this
295 bug.
296
1c736b78
SP
2973. Fixed dump's estimate when dealing with sparse inodes.
298
876861d2
SP
2994. Modified dump to allow setting a blocksize bigger than 32kB
300 (raised the limit to 1024kB), because newer hardware needs
301 this for proper operation. Thanks to Dirk Traenapp
302 <dtraenapp@users.sourceforge.net> for reporting this.
303
b8d848c9
SP
3045. Fixed a bug causing Dump to stop and report an error if an
305 inode number in the exclude file was followed by some amount
306 of whitespace. Thanks to Jeffrey Sofferin
307 <sofferin@users.sourceforge.net> for reporting this bug.
308
e531c442
SP
3096. Fixed a bug which caused restore, in some particular cases,
310 to ask some 'scary' questions and leave a bunch of RSTTMP
311 directories behind when restoring incremental tapes. Thanks
312 to Philippe Troin <phil@fifi.org> for reporting this bug and
313 providing the test cases.
314
c993d83a
SP
3157. Changed the wording when inodes are excluded from dump:
316 replaced 'Added inode 7 to exclude list' with
317 'Excluding inode 7 (resize inode) from dump', as suggested
318 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
319
cbc7fd6a 320Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
321===================================================================
322
3231. Fixed rmt open flags transmission (GNU's symbolic syntax over
324 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
325 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 326
4095abc0
SP
327Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
328===================================================================
aa1b1e7f
SP
329
3301. Made dump print out the ext2 logical block number in case of a read
331 error, which can be given as an argument to debugfs' ncheck command,
332 in order to find out the affected inode. Added note about this
333 usage in dump's man page.
ed7c25a3
SP
334
3352. Fixed a problem in restore when reading tapes written on big
336 endian machines with very old versions of dump. The patch was
337 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
338
3393. Fixed the tape length calculation when using large tapes
340 and compression. Thanks to Georg Lippold
341 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
342
3434. Added a new set of examples in dump_on_cd_2 directory, based
344 on dump_on_cd examples but somewhat enhanced, supporting DVD
345 media, and localized in english and german. Thanks to
346 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
347
9ca70cf6
SP
3485. Made dump save 32 bit UID/GID. Internally, this was achieved
349 by switching from the old BSD inode format to the new BSD
350 inode format, which means that the tape format was changed.
351 However, since all restore versions out there should
352 transparently support both inode formats, the change should
353 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
354 reporting the bug.
a18d5997
SP
355
3566. Fixed a lot of warnings in the code shown when compiling
357 with 'gcc -W'. Thanks to Matthias Andree
358 <matthias.andree@stud.uni-dortmund.de> for reporting this.
359
2a2e321d
SP
3607. Fixed a small markup bug in the dump man page. Thanks to
361 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
362 patch.
363
153f9a83
SP
3648. Rewrote entirely the man pages using the tmac.an macro
365 package (Linux man page format) instead of the original BSD
366 format. They should be now cleaner and easier to modify.
367

d24dc8af
SP
370
3711. Fixed a problem in the rmt ioctl command, where ioctl's issued from
372 non Linux clients were misinterpreted. The description of the problem
373 (incompatible numbering in Linux mtio opcodes) is documented at
374 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
375
