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>.

10Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
11=====================================================================
b79d20f1
SP
12
131. Fix a couple of troff syntax bugs in the man pages.
14 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 15
0556ca22
SP
162. Made restore use either libncurses or libtermcap, depending
17 on which one is available at configure time.
18
7d422735
SP
193. Fixed restore negative size display bug when comparing a
20 dump containing files over 2GB. Thanks to Steve Bonds
21 <sbonds@users.sourceforge.net> for the bug report.
22
585ca01a
SP
234. Do not save directory entries to non-dumped inodes
24 (excluded from dump). This will eliminate the 'missing
25 file' warnings when doing 'restore -C'.
26
241ddca3
SP
275. Fix dump crash when backuping a huge (2TB) filesystem,
28 due to a bogus calculation on the inode map size.
29 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
30 submitting the bug and testing the fix.
31
47acd076
SP
326. Fix a problem in restore where the final \0 in the symbolic
33 link names could have been lost, generating corrupt filenames.
34 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
35 bug.
36
741eb204
SP
377. Implemented a hash list for the directory names in restore.
38 The linear list used before caused problems in interactive
39 restores when dealing with directories having thousands of
40 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
41 for reporting the bug.
42
a55ce914
SP
438. Improved restore -C, this time including the directory
44 attributes into the comparision.
45
469. Made restore understand tapes containing EA/ACLs (which will
47 be dumped by the next version of dump). In this version
48 extended attributes on the tape are ignored, for full EA/ACL
49 support wait for the next version or try the experimental EA
50 patch.
51

SP
52Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
53==================================================================
d7783603
SP
54
551. Added the --enable-staticz configure option which enables
56 dump and restore to be linked with static versions of
57 libz and libbz2 (and dynamic versions of all other libraries).
58 This will make Debian users happy, because libz and libbz2
59 were the only needed libraries living in /usr, all the
60 others live in /lib. In case of system emergency, it is
61 better not to have to rely on an extra filesystem.
62 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 63
b3f55532
SP
642. Fix compilation on (at least the Linux Debian port to) AMD64.
65 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
66 that are also defined by <linux/types.h> (<asm/types.h>) and
67 they conflict).
68
1f2c193e
SP
693. Make dump's reading of the dumpdates file a bit more robust,
70 preventing dump from crashing when the dumpdates file has
71 been modified by hand.
72
e1e4be20
SP
734. Fixed some offset calculations in dump code which could
74 lead to "bread lseek errors" on large filesystems. Thanks
75 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
76 reporting this bug and debugging the issue.
77
c9e4e868
SP
785. Made dump use the blkid library when searching for devices
79 by label or uuid instead of dump's own routines.
80
97be3358
SP
816. Corrected a bug in dump where a wrong LABEL=... line in
82 /etc/fstab could prevent dump from dumping unrelated
83 filesystems. Thanks to Bruce Lowekamp
84 <lowekamp@users.sourceforge.net> for reporting the bug.
85
ddf54486
SP
86Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
87====================================================================
e0267986
SP
88
891. Fixed dump compilation with old gcc versions. Thanks to
90 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 91
75654eee
SP
922. Fixed some warnings (howmany, roundup, powerof2 redefined)
93 when compiling against a recent glibc version.
94
43e6ea49
SP
953. Fixed a bug in restore preventing the read of a dump tape
96 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
97 <phiggins@transzap.com> for reporting the bug and providing
98 the test case.
99
d435f57f
SP
1004. Changed dump to enable the creation of volumes of different
101 sizes in a single run (make -B accept a list of values).
102 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
103
e1ba02ef
SP
1045. Use the glibc provided minor() and major() macros instead
105 of our own bitmask implementation. This should be safe for
106 when the major/minor namespace will migrate to 32 bits.
107 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
108 the bug.
109
ae6919a7
SP
1106. Made explicit in the dump man page that dump will not create
111 a remote file, it will only write to an already existing one.
112
4acaf865
SP
1137. Another try at making size estimates better again.
114
956756f2
SP
1158. Put back the inconditional running of the end-of-tape
116 script which was changed in 0.434 to be run only when -M
117 or multiple -f were NOT specified. Some users rely on this
118 feature even when it is combined with -M/-f.
119
e4e31ce9
SP
1209. Fixed restore when restoring huge backups (where rstdir...
121 temporary files are over 2GB). Thanks to
122 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
123 debugging the issue and making the patch.
124
cc7747eb
SP
12510. Made restore understand FreeBSD UFS2 tapes. Thanks to
126 David <vrtin@users.sourceforge.net> for submitting the bug
127 and providing a test case.
128
28ba5cae
SP
12911. Made dump work with an arbitrary integer level (no more 10
130 levels only limitation). Thanks to Matthew
131 <msvincen@midway.uchicago.edu> for the patch.
132
dcac75e9
SP
133Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
134=======================================================================
8ad151aa
SP
135
1361. Added a note in the dump man page saying that the default
137 blocksize can be 32 if -d is used with a high density argument.
138 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
139 for the patch.
ed194aec 140
008af419
SP
1412. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
142 LDFLAGS environment variables. Thanks to Arcady Genkin
143 <antipode@users.sourceforge.net> for reporting the bug.
144
0d4dfd07 1453. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
146 to be excluded, rather than a hardcoded maximum. Thanks to
147 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
148
0d4dfd07
SP
1494. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
150 and -D_USE_BSD_SIGNAL defines in configure in order to solve
151 64bit build problems because quad_t is redifined with a
152 different signature. Thanks to Mike Harris <mharris@redhat.com>
153 for reporting this bug.
154
5d8d264f 1555. Made restore build on Solaris, making possible to
d1925e0c
SP
156 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
157 <uwe@ugsoft.de> for the patch.
158
1596. Made an extension in the dump tape format capable of saving
160 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
161 wrote the extension and contributed the restore code back
162 into this codebase. The same extension mechanism will be
163 used in the future to save ACLs...
164
1657. Made rmt work correctly with regard to QFA and local/remote
166 files and tapes. The remote access will however work only
167 when the dump provided rmt version is used. If you want to
168 use another rmt server, please do not use the QFA feature.
5d8d264f 169 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.

171Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
172====================================================================
ed194aec
SP
173
1741. Fixed the INSTALL file to reflect the actual install paths.
175 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
176 reporting the bug.
4bb009da 177
d3e542e7
SP
1782. Fixed the configure script to only check for headers presence
179 instead of trying to compile them. This should fix issues
180 with old build environments. Thanks to Kari Lempiainen
181 <kari@funky.pp.fi> for reporting the bug.
182
1176b3c1
SP
1833. Fixed restore to correctly ignore sockets when comparing
184 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
185 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
186
1874. Fixed restore to correctly access the archive file (-A argument)
188 even when using a remote tape. Thanks to Fabrice Bellet
189 <fabrice@bellet.info> for reporting the bug.
1176b3c1 190
900bffdb
SP
1915. Fixed (again) handling of long (largefile) seeks in rmt.
192 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
193 the bug.
194
6d834d25
SP
1956. Fixed restore corner case when dealing with large block sizes
196 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
197 <fabrice@bellet.info> for reporting the bug.
198
cdef84ca
SP
1997. Fixed a bug preventing dump to access a filesystem having
200 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
201 for reporting the bug.
202
3458b64d
SP
2038. Made dump store dump dates using explicit timezones, fixing a
204 problem with incremental dumps if the timezone is modified
205 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
206 the bug report and the patch.
207
2be77799
SP
2089. Fixed a bug encountered when dumping individual files (not full
209 filesystems or directories) and dangling symbolic links happen
210 to be in the list of files. For as far as dump is concerned,
211 dangling symbolic links are allowed, and are dumped as is.
212 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
213 bug and providing the fix.
214
c3f69f06
SP
21510. Fixed open and creation modes and permissions for QFA and
216 table-of-contents files in dump and restore. Thanks to
217 Philippe Troin <phil@fifi.org> for the patch.
218
21911. Fixed the archive file descriptor handling enabling it to be 0.
220 This can happen in some cases when shell redirections are used.
221 Thanks to Philippe Troin <phil@fifi.org> for the patch.
222
22312. Delayed the opening of archive file until after suid had been
224 dropped (fixing a possible security issue if dump is suid).
225 Thanks to Philippe Troin <phil@fifi.org> for the patch.
226
22713. Fixed the 'S' command handling in the rmt client part.
228 Thanks to Philippe Troin <phil@fifi.org> for the patch.
229
23014. Modified the end-of-tape script handling to print out statistics
231 (and stop the timer) before launching the eot script. Also, the eot
232 script does not get run anymore when using -M (which makes sense) or
233 when multiple tapes are listed on the command line
234 (-f tape0,tape1,tapen) (which also makes sense).
235 Thanks to Philippe Troin <phil@fifi.org> for the patch.
236
e1abc9ce
SP
23715. Relicensed dump/restore under the 'revised' BSD license, as per
238 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
239
206f768c
SP
24016. Added LZO compression to dump. This new compression method has
241 the advantage of being super fast, thus not killing tape streaming
242 on slow machines. Thanks to Helmut Jarausch
243 <jarausch@igpm.rwth-aachen.de> for the patch and to
244 Markus Oberhumer <markus@oberhumer.com> for giving special permission
245 to include his miniLZO project (GPL licensed) in dump/restore.
246
e2392789
SP
24717. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
248 <ant@notatla.demon.co.uk> for reporting the bugs.
249
cdfe1392
SP
25018. Added a special rmt version which can do encryption when writing
251 to tape. Read examples/encrypted_rmt/README for details on
252 how to enable and configure it. Thanks to Ken Lalonde
253 <ken@globalremit.com> for the patch.
254
61e9d4ff
SP
25519. Made dump work with 2.5 kernel end of tape early warning semantics.
256 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
257
8c95cc30
SP
25820. Fixed a bug which caused dump -w|-W not to work anymore, because
259 the fs_freq and fs_passno fields in /etc/mtab are always set
260 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
261 reporting the bug.
262
cbdba727 263Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
264=======================================================================
265
2661. Added a note in the restore man page clarifying the question
267 'set the permissions on the current directory ?' asked by
268 restore at the end of treatment in -i and -x modes.
d86089d1 269
c898ca7a
SP
2702. Fixed the endianess issues when reading compressed tapes.
271 Thanks to Dark Force <daq4th@users.sourceforge.net> for
272 reporting this bug and providing test cases.
273
a028bdc8
SP
2743. Fixed the "ACL won't be dumped" warning message (which showed
275 an extra, unrelated error message). Thanks to Dragan Krnic
276 <dkrnic@lycos.com> for reporting this bug.
277
a8a6a503 2784. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
279 when searching for filesystem paths. Also fixed some problems
280 caused by binding mounts or multiple block device mounts.
281 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
282 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
283 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
284 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 285
3211c85b
SP
2865. Made dump's -I option accept the value '0' meaning all the
287 read errors will be ignored. This can be useful when running
288 dump from unattended sessions (like cron jobs). Thanks to
289 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
290
7fcd6df5
SP
2916. Fixed the output of dump to indicate 'blocks' instead of
292 'tape blocks' in the various messages (blocks are always
293 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
294 made it clearly print the current blocksize at the start of
295 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
296 the suggestions.
297
5bf65105
SP
2987. Made rmt understand long (largefiles) seeks.
299
dbb649e8
SP
3008. Fixed build with very old versions of libext2fs, where
301 EXT2_FT_* constants were undefined.
302
c92d83ae
SP
3039. Made dump accept the dumpdates path on the command line
304 (-D file option) instead of using only the hardcoded one.
305 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
306 suggestion.
307
1daf06b9
SP
30810. Enabled rmt, LFS, readline, QFA options by default in
309 ./configure. Updated the configure process (new versions
310 of config.guess, config.sub etc).
311
51c11d00
SP
312Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
313=======================================================================
d86089d1
SP
314
3151. Changed dump to use fcntl(F_SETLK) style locking instead
316 of flock() when locking the dumpdates file. With the old
317 locking scheme, a local user having read rights on the
318 dumpdates file could be able to do a Denial of Service attack
319 on dump. In order to lock the dumpdates file with the new
320 scheme, the user would need to have write access on the file.
321 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
322 reporting the bug (originally a bugtraq post).
ba3af39e 323
2f562f4e
SP
3242. Fixed interactive 'ls' which caused spurious errors warnings
325 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
326 <jorgen_ostling@users.sourceforge.net> for reporting this
327 bug.
328
1c736b78
SP
3293. Fixed dump's estimate when dealing with sparse inodes.
330
876861d2
SP
3314. Modified dump to allow setting a blocksize bigger than 32kB
332 (raised the limit to 1024kB), because newer hardware needs
333 this for proper operation. Thanks to Dirk Traenapp
334 <dtraenapp@users.sourceforge.net> for reporting this.
335
b8d848c9
SP
3365. Fixed a bug causing Dump to stop and report an error if an
337 inode number in the exclude file was followed by some amount
338 of whitespace. Thanks to Jeffrey Sofferin
339 <sofferin@users.sourceforge.net> for reporting this bug.
340
e531c442
SP
3416. Fixed a bug which caused restore, in some particular cases,
342 to ask some 'scary' questions and leave a bunch of RSTTMP
343 directories behind when restoring incremental tapes. Thanks
344 to Philippe Troin <phil@fifi.org> for reporting this bug and
345 providing the test cases.
346
c993d83a
SP
3477. Changed the wording when inodes are excluded from dump:
348 replaced 'Added inode 7 to exclude list' with
349 'Excluding inode 7 (resize inode) from dump', as suggested
350 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
351
cbc7fd6a 352Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
353===================================================================
354
3551. Fixed rmt open flags transmission (GNU's symbolic syntax over
356 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
357 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 358

359Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
360===================================================================
aa1b1e7f
SP
361
3621. Made dump print out the ext2 logical block number in case of a read
363 error, which can be given as an argument to debugfs' ncheck command,
364 in order to find out the affected inode. Added note about this
365 usage in dump's man page.
ed7c25a3
SP
366
3672. Fixed a problem in restore when reading tapes written on big
368 endian machines with very old versions of dump. The patch was
369 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
370
3713. Fixed the tape length calculation when using large tapes
372 and compression. Thanks to Georg Lippold
373 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
374
3754. Added a new set of examples in dump_on_cd_2 directory, based
376 on dump_on_cd examples but somewhat enhanced, supporting DVD
377 media, and localized in english and german. Thanks to
378 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
379
9ca70cf6
SP
3805. Made dump save 32 bit UID/GID. Internally, this was achieved
381 by switching from the old BSD inode format to the new BSD
382 inode format, which means that the tape format was changed.
383 However, since all restore versions out there should
384 transparently support both inode formats, the change should
385 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
386 reporting the bug.
a18d5997
SP
387
3886. Fixed a lot of warnings in the code shown when compiling
389 with 'gcc -W'. Thanks to Matthias Andree
390 <matthias.andree@stud.uni-dortmund.de> for reporting this.
391
2a2e321d
SP
3927. Fixed a small markup bug in the dump man page. Thanks to
393 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
394 patch.
395
153f9a83
SP
3968. Rewrote entirely the man pages using the tmac.an macro
397 package (Linux man page format) instead of the original BSD
398 format. They should be now cleaner and easier to modify.

401==================================================================
d24dc8af
SP
402
4031. Fixed a problem in the rmt ioctl command, where ioctl's issued from
404 non Linux clients were misinterpreted. The description of the problem
405 (incompatible numbering in Linux mtio opcodes) is documented at
406 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
407
