3Changes between versions 0.4b38 and 0.4b39 (released ???????????????)
4=====================================================================
5
61. The newly added dump_on_cd_3 example was buggy, replace it
7 with an updated version from Andrew Basterfield
8 <bob@cemetery.homeunix.org>.
b79d20f1 9
30e8407d
SP
102. Made restore to chdir() back into the initial directory when
11 dumping core while aborting a comparision operation. The
12 previous behaviour was to write the corefile at the root of
13 the directory being compared, which could very well be
14 read only and preventing the corefile generation. Thanks
15 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
16
b43981b3
SP
173. Silenced the failure to call fgetflags() when comparing an
18 entry which has no ext2 attributes (as in lsattr()).
19
68415469
SP
204. Fix a brown paper bug in restore -C which broke restore and
21 caused modifications on the filesystem being compared
22 (directories containing a file with the same name as the
23 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
24 <shiva@sewingwitch.com> for finding the bug and helping me
25 reproduce it.
26
18dc6e86
SP
275. Made restore -C force the -N flag (no writing allowed on
28 the disk) in order to prevent more bugs like the above one.

30Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
31=====================================================================
b79d20f1
SP
32
331. Fix a couple of troff syntax bugs in the man pages.
34 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 35
0556ca22
SP
362. Made restore use either libncurses or libtermcap, depending
37 on which one is available at configure time.
38
7d422735
SP
393. Fixed restore negative size display bug when comparing a
40 dump containing files over 2GB. Thanks to Steve Bonds
41 <sbonds@users.sourceforge.net> for the bug report.
42
585ca01a
SP
434. Do not save directory entries to non-dumped inodes
44 (excluded from dump). This will eliminate the 'missing
45 file' warnings when doing 'restore -C'.
46
241ddca3
SP
475. Fix dump crash when backuping a huge (2TB) filesystem,
48 due to a bogus calculation on the inode map size.
49 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
50 submitting the bug and testing the fix.
51
47acd076
SP
526. Fix a problem in restore where the final \0 in the symbolic
53 link names could have been lost, generating corrupt filenames.
54 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
55 bug.
56
741eb204
SP
577. Implemented a hash list for the directory names in restore.
58 The linear list used before caused problems in interactive
59 restores when dealing with directories having thousands of
60 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
61 for reporting the bug.
62
a55ce914
SP
638. Improved restore -C, this time including the directory
64 attributes into the comparision.
65
669. Made restore understand tapes containing EA/ACLs (which will
67 be dumped by the next version of dump). In this version
68 extended attributes on the tape are ignored, for full EA/ACL
69 support wait for the next version or try the experimental EA
70 patch.
71
498a402f
SP
72Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
73==================================================================
d7783603
SP
74
751. Added the --enable-staticz configure option which enables
76 dump and restore to be linked with static versions of
77 libz and libbz2 (and dynamic versions of all other libraries).
78 This will make Debian users happy, because libz and libbz2
79 were the only needed libraries living in /usr, all the
80 others live in /lib. In case of system emergency, it is
81 better not to have to rely on an extra filesystem.
82 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 83
b3f55532
SP
842. Fix compilation on (at least the Linux Debian port to) AMD64.
85 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
86 that are also defined by <linux/types.h> (<asm/types.h>) and
87 they conflict).
88
1f2c193e
SP
893. Make dump's reading of the dumpdates file a bit more robust,
90 preventing dump from crashing when the dumpdates file has
91 been modified by hand.
92
e1e4be20
SP
934. Fixed some offset calculations in dump code which could
94 lead to "bread lseek errors" on large filesystems. Thanks
95 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
96 reporting this bug and debugging the issue.
97
c9e4e868
SP
985. Made dump use the blkid library when searching for devices
99 by label or uuid instead of dump's own routines.
100
97be3358
SP
1016. Corrected a bug in dump where a wrong LABEL=... line in
102 /etc/fstab could prevent dump from dumping unrelated
103 filesystems. Thanks to Bruce Lowekamp
104 <lowekamp@users.sourceforge.net> for reporting the bug.
105
ddf54486
SP
106Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
107====================================================================
e0267986
SP
108
1091. Fixed dump compilation with old gcc versions. Thanks to
110 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 111
75654eee
SP
1122. Fixed some warnings (howmany, roundup, powerof2 redefined)
113 when compiling against a recent glibc version.
114
43e6ea49
SP
1153. Fixed a bug in restore preventing the read of a dump tape
116 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
117 <phiggins@transzap.com> for reporting the bug and providing
118 the test case.
119
d435f57f
SP
1204. Changed dump to enable the creation of volumes of different
121 sizes in a single run (make -B accept a list of values).
122 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
123
e1ba02ef
SP
1245. Use the glibc provided minor() and major() macros instead
125 of our own bitmask implementation. This should be safe for
126 when the major/minor namespace will migrate to 32 bits.
127 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
128 the bug.
129
ae6919a7
SP
1306. Made explicit in the dump man page that dump will not create
131 a remote file, it will only write to an already existing one.
132
4acaf865
SP
1337. Another try at making size estimates better again.
134
956756f2
SP
1358. Put back the inconditional running of the end-of-tape
136 script which was changed in 0.434 to be run only when -M
137 or multiple -f were NOT specified. Some users rely on this
138 feature even when it is combined with -M/-f.
139
e4e31ce9
SP
1409. Fixed restore when restoring huge backups (where rstdir...
141 temporary files are over 2GB). Thanks to
142 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
143 debugging the issue and making the patch.
144
cc7747eb
SP
14510. Made restore understand FreeBSD UFS2 tapes. Thanks to
146 David <vrtin@users.sourceforge.net> for submitting the bug
147 and providing a test case.
148
28ba5cae
SP
14911. Made dump work with an arbitrary integer level (no more 10
150 levels only limitation). Thanks to Matthew
151 <msvincen@midway.uchicago.edu> for the patch.
152
dcac75e9
SP
153Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
154=======================================================================
8ad151aa
SP
155
1561. Added a note in the dump man page saying that the default
157 blocksize can be 32 if -d is used with a high density argument.
158 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
159 for the patch.
ed194aec 160
008af419
SP
1612. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
162 LDFLAGS environment variables. Thanks to Arcady Genkin
163 <antipode@users.sourceforge.net> for reporting the bug.
164
0d4dfd07 1653. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
166 to be excluded, rather than a hardcoded maximum. Thanks to
167 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
168
0d4dfd07
SP
1694. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
170 and -D_USE_BSD_SIGNAL defines in configure in order to solve
171 64bit build problems because quad_t is redifined with a
172 different signature. Thanks to Mike Harris <mharris@redhat.com>
173 for reporting this bug.
174
5d8d264f 1755. Made restore build on Solaris, making possible to
d1925e0c
SP
176 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
177 <uwe@ugsoft.de> for the patch.
178
1796. Made an extension in the dump tape format capable of saving
180 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
181 wrote the extension and contributed the restore code back
182 into this codebase. The same extension mechanism will be
183 used in the future to save ACLs...
184
1857. Made rmt work correctly with regard to QFA and local/remote
186 files and tapes. The remote access will however work only
187 when the dump provided rmt version is used. If you want to
188 use another rmt server, please do not use the QFA feature.
5d8d264f 189 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 190
b564cb84
SP
191Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
192====================================================================
ed194aec
SP
193
1941. Fixed the INSTALL file to reflect the actual install paths.
195 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
196 reporting the bug.
4bb009da 197
d3e542e7
SP
1982. Fixed the configure script to only check for headers presence
199 instead of trying to compile them. This should fix issues
200 with old build environments. Thanks to Kari Lempiainen
201 <kari@funky.pp.fi> for reporting the bug.
202
1176b3c1
SP
2033. Fixed restore to correctly ignore sockets when comparing
204 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
205 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
206
2074. Fixed restore to correctly access the archive file (-A argument)
208 even when using a remote tape. Thanks to Fabrice Bellet
209 <fabrice@bellet.info> for reporting the bug.
1176b3c1 210
900bffdb
SP
2115. Fixed (again) handling of long (largefile) seeks in rmt.
212 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
213 the bug.
214
6d834d25
SP
2156. Fixed restore corner case when dealing with large block sizes
216 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
217 <fabrice@bellet.info> for reporting the bug.
218
cdef84ca
SP
2197. Fixed a bug preventing dump to access a filesystem having
220 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
221 for reporting the bug.
222
3458b64d
SP
2238. Made dump store dump dates using explicit timezones, fixing a
224 problem with incremental dumps if the timezone is modified
225 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
226 the bug report and the patch.
227
2be77799
SP
2289. Fixed a bug encountered when dumping individual files (not full
229 filesystems or directories) and dangling symbolic links happen
230 to be in the list of files. For as far as dump is concerned,
231 dangling symbolic links are allowed, and are dumped as is.
232 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
233 bug and providing the fix.
234
c3f69f06
SP
23510. Fixed open and creation modes and permissions for QFA and
236 table-of-contents files in dump and restore. Thanks to
237 Philippe Troin <phil@fifi.org> for the patch.
238
23911. Fixed the archive file descriptor handling enabling it to be 0.
240 This can happen in some cases when shell redirections are used.
241 Thanks to Philippe Troin <phil@fifi.org> for the patch.
242
24312. Delayed the opening of archive file until after suid had been
244 dropped (fixing a possible security issue if dump is suid).
245 Thanks to Philippe Troin <phil@fifi.org> for the patch.
246
24713. Fixed the 'S' command handling in the rmt client part.
248 Thanks to Philippe Troin <phil@fifi.org> for the patch.
249
25014. Modified the end-of-tape script handling to print out statistics
251 (and stop the timer) before launching the eot script. Also, the eot
252 script does not get run anymore when using -M (which makes sense) or
253 when multiple tapes are listed on the command line
254 (-f tape0,tape1,tapen) (which also makes sense).
255 Thanks to Philippe Troin <phil@fifi.org> for the patch.
256
e1abc9ce
SP
25715. Relicensed dump/restore under the 'revised' BSD license, as per
258 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
259
206f768c
SP
26016. Added LZO compression to dump. This new compression method has
261 the advantage of being super fast, thus not killing tape streaming
262 on slow machines. Thanks to Helmut Jarausch
263 <jarausch@igpm.rwth-aachen.de> for the patch and to
264 Markus Oberhumer <markus@oberhumer.com> for giving special permission
265 to include his miniLZO project (GPL licensed) in dump/restore.
266
e2392789
SP
26717. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
268 <ant@notatla.demon.co.uk> for reporting the bugs.
269
cdfe1392
SP
27018. Added a special rmt version which can do encryption when writing
271 to tape. Read examples/encrypted_rmt/README for details on
272 how to enable and configure it. Thanks to Ken Lalonde
273 <ken@globalremit.com> for the patch.
274
61e9d4ff
SP
27519. Made dump work with 2.5 kernel end of tape early warning semantics.
276 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
277
8c95cc30
SP
27820. Fixed a bug which caused dump -w|-W not to work anymore, because
279 the fs_freq and fs_passno fields in /etc/mtab are always set
280 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
281 reporting the bug.
282
cbdba727 283Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
284=======================================================================
285
2861. Added a note in the restore man page clarifying the question
287 'set the permissions on the current directory ?' asked by
288 restore at the end of treatment in -i and -x modes.
d86089d1 289
c898ca7a
SP
2902. Fixed the endianess issues when reading compressed tapes.
291 Thanks to Dark Force <daq4th@users.sourceforge.net> for
292 reporting this bug and providing test cases.
293
a028bdc8
SP
2943. Fixed the "ACL won't be dumped" warning message (which showed
295 an extra, unrelated error message). Thanks to Dragan Krnic
296 <dkrnic@lycos.com> for reporting this bug.
297
a8a6a503 2984. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
299 when searching for filesystem paths. Also fixed some problems
300 caused by binding mounts or multiple block device mounts.
301 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
302 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
303 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
304 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 305
3211c85b
SP
3065. Made dump's -I option accept the value '0' meaning all the
307 read errors will be ignored. This can be useful when running
308 dump from unattended sessions (like cron jobs). Thanks to
309 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
310
7fcd6df5
SP
3116. Fixed the output of dump to indicate 'blocks' instead of
312 'tape blocks' in the various messages (blocks are always
313 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
314 made it clearly print the current blocksize at the start of
315 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
316 the suggestions.
317
5bf65105
SP
3187. Made rmt understand long (largefiles) seeks.
319
dbb649e8
SP
3208. Fixed build with very old versions of libext2fs, where
321 EXT2_FT_* constants were undefined.
322
c92d83ae
SP
3239. Made dump accept the dumpdates path on the command line
324 (-D file option) instead of using only the hardcoded one.
325 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
326 suggestion.
327
1daf06b9
SP
32810. Enabled rmt, LFS, readline, QFA options by default in
329 ./configure. Updated the configure process (new versions
330 of config.guess, config.sub etc).
331
51c11d00
SP
332Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
333=======================================================================
d86089d1
SP
334
3351. Changed dump to use fcntl(F_SETLK) style locking instead
336 of flock() when locking the dumpdates file. With the old
337 locking scheme, a local user having read rights on the
338 dumpdates file could be able to do a Denial of Service attack
339 on dump. In order to lock the dumpdates file with the new
340 scheme, the user would need to have write access on the file.
341 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
342 reporting the bug (originally a bugtraq post).
ba3af39e 343
2f562f4e
SP
3442. Fixed interactive 'ls' which caused spurious errors warnings
345 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
346 <jorgen_ostling@users.sourceforge.net> for reporting this
347 bug.
348
1c736b78
SP
3493. Fixed dump's estimate when dealing with sparse inodes.
350
876861d2
SP
3514. Modified dump to allow setting a blocksize bigger than 32kB
352 (raised the limit to 1024kB), because newer hardware needs
353 this for proper operation. Thanks to Dirk Traenapp
354 <dtraenapp@users.sourceforge.net> for reporting this.
355
b8d848c9
SP
3565. Fixed a bug causing Dump to stop and report an error if an
357 inode number in the exclude file was followed by some amount
358 of whitespace. Thanks to Jeffrey Sofferin
359 <sofferin@users.sourceforge.net> for reporting this bug.
360
e531c442
SP
3616. Fixed a bug which caused restore, in some particular cases,
362 to ask some 'scary' questions and leave a bunch of RSTTMP
363 directories behind when restoring incremental tapes. Thanks
364 to Philippe Troin <phil@fifi.org> for reporting this bug and
365 providing the test cases.
366
c993d83a
SP
3677. Changed the wording when inodes are excluded from dump:
368 replaced 'Added inode 7 to exclude list' with
369 'Excluding inode 7 (resize inode) from dump', as suggested
370 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
371
cbc7fd6a 372Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
373===================================================================
374
3751. Fixed rmt open flags transmission (GNU's symbolic syntax over
376 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
377 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 378
4095abc0
SP
379Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
380===================================================================
aa1b1e7f
SP
381
3821. Made dump print out the ext2 logical block number in case of a read
383 error, which can be given as an argument to debugfs' ncheck command,
384 in order to find out the affected inode. Added note about this
385 usage in dump's man page.
ed7c25a3
SP
386
3872. Fixed a problem in restore when reading tapes written on big
388 endian machines with very old versions of dump. The patch was
389 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
390
3913. Fixed the tape length calculation when using large tapes
392 and compression. Thanks to Georg Lippold
393 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
394
3954. Added a new set of examples in dump_on_cd_2 directory, based
396 on dump_on_cd examples but somewhat enhanced, supporting DVD
397 media, and localized in english and german. Thanks to
398 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
399
9ca70cf6
SP
4005. Made dump save 32 bit UID/GID. Internally, this was achieved
401 by switching from the old BSD inode format to the new BSD
402 inode format, which means that the tape format was changed.
403 However, since all restore versions out there should
404 transparently support both inode formats, the change should
405 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
406 reporting the bug.
a18d5997
SP
407
4086. Fixed a lot of warnings in the code shown when compiling
409 with 'gcc -W'. Thanks to Matthias Andree
410 <matthias.andree@stud.uni-dortmund.de> for reporting this.
411
2a2e321d
SP
4127. Fixed a small markup bug in the dump man page. Thanks to
413 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
414 patch.
415
153f9a83
SP
4168. Rewrote entirely the man pages using the tmac.an macro
417 package (Linux man page format) instead of the original BSD
418 format. They should be now cleaner and easier to modify.
419

4231. Fixed a problem in the rmt ioctl command, where ioctl's issued from
424 non Linux clients were misinterpreted. The description of the problem
425 (incompatible numbering in Linux mtio opcodes) is documented at
426 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
