2
3 Changes between versions 0.4b34 and 0.4b35 (released ??????????????)
4 ====================================================================
5
6 1. Added a note in the dump man page saying that the default
7 blocksize can be 32 if -d is used with a high density argument.
8 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
9 for the patch.
10
11 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
12 LDFLAGS environment variables. Thanks to Arcady Genkin
13 <antipode@users.sourceforge.net> for reporting the bug.
14
15 3. Made -e/-E options of dump accept an unlimited number of inodes
16 to be excluded, rather than a hardcoded maximum. Thanks to
17 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
18
19 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
20 and -D_USE_BSD_SIGNAL defines in configure in order to solve
21 64bit build problems because quad_t is redifined with a
22 different signature. Thanks to Mike Harris <mharris@redhat.com>
23 for reporting this bug.
24
25 5. Made dump/restore build on Solaris, making possible to
26 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
27 <uwe@ugsoft.de> for the patch.
28
29 6. Made an extension in the dump tape format capable of saving
30 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
31 wrote the extension and contributed the restore code back
32 into this codebase. The same extension mechanism will be
33 used in the future to save ACLs...
34
35 7. Made rmt work correctly with regard to QFA and local/remote
36 files and tapes. The remote access will however work only
37 when the dump provided rmt version is used. If you want to
38 use another rmt server, please do not use the QFA feature.
39
40 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
41 ====================================================================
42
43 1. Fixed the INSTALL file to reflect the actual install paths.
44 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
45 reporting the bug.
46
47 2. Fixed the configure script to only check for headers presence
48 instead of trying to compile them. This should fix issues
49 with old build environments. Thanks to Kari Lempiainen
50 <kari@funky.pp.fi> for reporting the bug.
51
52 3. Fixed restore to correctly ignore sockets when comparing
53 a dump (as socket cannot be properly restored anyway). Thanks
54 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
55
56 4. Fixed restore to correctly access the archive file (-A argument)
57 even when using a remote tape. Thanks to Fabrice Bellet
58 <fabrice@bellet.info> for reporting the bug.
59
60 5. Fixed (again) handling of long (largefile) seeks in rmt.
61 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
62 the bug.
63
64 6. Fixed restore corner case when dealing with large block sizes
65 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
66 <fabrice@bellet.info> for reporting the bug.
67
68 7. Fixed a bug preventing dump to access a filesystem having
69 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
70 for reporting the bug.
71
72 8. Made dump store dump dates using explicit timezones, fixing a
73 problem with incremental dumps if the timezone is modified
74 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
75 the bug report and the patch.
76
77 9. Fixed a bug encountered when dumping individual files (not full
78 filesystems or directories) and dangling symbolic links happen
79 to be in the list of files. For as far as dump is concerned,
80 dangling symbolic links are allowed, and are dumped as is.
81 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
82 bug and providing the fix.
83
84 10. Fixed open and creation modes and permissions for QFA and
85 table-of-contents files in dump and restore. Thanks to
86 Philippe Troin <phil@fifi.org> for the patch.
87
88 11. Fixed the archive file descriptor handling enabling it to be 0.
89 This can happen in some cases when shell redirections are used.
90 Thanks to Philippe Troin <phil@fifi.org> for the patch.
91
92 12. Delayed the opening of archive file until after suid had been
93 dropped (fixing a possible security issue if dump is suid).
94 Thanks to Philippe Troin <phil@fifi.org> for the patch.
95
96 13. Fixed the 'S' command handling in the rmt client part.
97 Thanks to Philippe Troin <phil@fifi.org> for the patch.
98
99 14. Modified the end-of-tape script handling to print out statistics
100 (and stop the timer) before launching the eot script. Also, the eot
101 script does not get run anymore when using -M (which makes sense) or
102 when multiple tapes are listed on the command line
103 (-f tape0,tape1,tapen) (which also makes sense).
104 Thanks to Philippe Troin <phil@fifi.org> for the patch.
105
106 15. Relicensed dump/restore under the 'revised' BSD license, as per
107 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
108
109 16. Added LZO compression to dump. This new compression method has
110 the advantage of being super fast, thus not killing tape streaming
111 on slow machines. Thanks to Helmut Jarausch
112 <jarausch@igpm.rwth-aachen.de> for the patch and to
113 Markus Oberhumer <markus@oberhumer.com> for giving special permission
114 to include his miniLZO project (GPL licensed) in dump/restore.
115
116 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
117 <ant@notatla.demon.co.uk> for reporting the bugs.
118
119 18. Added a special rmt version which can do encryption when writing
120 to tape. Read examples/encrypted_rmt/README for details on
121 how to enable and configure it. Thanks to Ken Lalonde
122 <ken@globalremit.com> for the patch.
123
124 19. Made dump work with 2.5 kernel end of tape early warning semantics.
125 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
126
127 20. Fixed a bug which caused dump -w|-W not to work anymore, because
128 the fs_freq and fs_passno fields in /etc/mtab are always set
129 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
130 reporting the bug.
131
132 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
133 =======================================================================
134
135 1. Added a note in the restore man page clarifying the question
136 'set the permissions on the current directory ?' asked by
137 restore at the end of treatment in -i and -x modes.
138
139 2. Fixed the endianess issues when reading compressed tapes.
140 Thanks to Dark Force <daq4th@users.sourceforge.net> for
141 reporting this bug and providing test cases.
142
143 3. Fixed the "ACL won't be dumped" warning message (which showed
144 an extra, unrelated error message). Thanks to Dragan Krnic
145 <dkrnic@lycos.com> for reporting this bug.
146
147 4. Made dump look first into /etc/mtab, then into /etc/fstab
148 when searching for filesystem paths. Also fixed some problems
149 caused by binding mounts or multiple block device mounts.
150 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
151 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
152 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
153 and #160305, Sourceforge bugs #618699 and #679832).
154
155 5. Made dump's -I option accept the value '0' meaning all the
156 read errors will be ignored. This can be useful when running
157 dump from unattended sessions (like cron jobs). Thanks to
158 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
159
160 6. Fixed the output of dump to indicate 'blocks' instead of
161 'tape blocks' in the various messages (blocks are always
162 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
163 made it clearly print the current blocksize at the start of
164 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
165 the suggestions.
166
167 7. Made rmt understand long (largefiles) seeks.
168
169 8. Fixed build with very old versions of libext2fs, where
170 EXT2_FT_* constants were undefined.
171
172 9. Made dump accept the dumpdates path on the command line
173 (-D file option) instead of using only the hardcoded one.
174 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
175 suggestion.
176
177 10. Enabled rmt, LFS, readline, QFA options by default in
178 ./configure. Updated the configure process (new versions
179 of config.guess, config.sub etc).
180
181 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
182 =======================================================================
183
184 1. Changed dump to use fcntl(F_SETLK) style locking instead
185 of flock() when locking the dumpdates file. With the old
186 locking scheme, a local user having read rights on the
187 dumpdates file could be able to do a Denial of Service attack
188 on dump. In order to lock the dumpdates file with the new
189 scheme, the user would need to have write access on the file.
190 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
191 reporting the bug (originally a bugtraq post).
192
193 2. Fixed interactive 'ls' which caused spurious errors warnings
194 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
195 <jorgen_ostling@users.sourceforge.net> for reporting this
196 bug.
197
198 3. Fixed dump's estimate when dealing with sparse inodes.
199
200 4. Modified dump to allow setting a blocksize bigger than 32kB
201 (raised the limit to 1024kB), because newer hardware needs
202 this for proper operation. Thanks to Dirk Traenapp
203 <dtraenapp@users.sourceforge.net> for reporting this.
204
205 5. Fixed a bug causing Dump to stop and report an error if an
206 inode number in the exclude file was followed by some amount
207 of whitespace. Thanks to Jeffrey Sofferin
208 <sofferin@users.sourceforge.net> for reporting this bug.
209
210 6. Fixed a bug which caused restore, in some particular cases,
211 to ask some 'scary' questions and leave a bunch of RSTTMP
212 directories behind when restoring incremental tapes. Thanks
213 to Philippe Troin <phil@fifi.org> for reporting this bug and
214 providing the test cases.
215
216 7. Changed the wording when inodes are excluded from dump:
217 replaced 'Added inode 7 to exclude list' with
218 'Excluding inode 7 (resize inode) from dump', as suggested
219 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
220
221 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
222 ===================================================================
223
224 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
225 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
226 <eros@lamel.bo.cnr.it> for reporting the bug.
227
228 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
229 ===================================================================
230
231 1. Made dump print out the ext2 logical block number in case of a read
232 error, which can be given as an argument to debugfs' ncheck command,
233 in order to find out the affected inode. Added note about this
234 usage in dump's man page.
235
236 2. Fixed a problem in restore when reading tapes written on big
237 endian machines with very old versions of dump. The patch was
238 contributed by George Helffrich <george@geology.bristol.ac.uk>.
239
240 3. Fixed the tape length calculation when using large tapes
241 and compression. Thanks to Georg Lippold
242 <g_lippold@sourceforge.net> for reporting the bug.
243
244 4. Added a new set of examples in dump_on_cd_2 directory, based
245 on dump_on_cd examples but somewhat enhanced, supporting DVD
246 media, and localized in english and german. Thanks to
247 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
248
249 5. Made dump save 32 bit UID/GID. Internally, this was achieved
250 by switching from the old BSD inode format to the new BSD
251 inode format, which means that the tape format was changed.
252 However, since all restore versions out there should
253 transparently support both inode formats, the change should
254 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
255 reporting the bug.
256
257 6. Fixed a lot of warnings in the code shown when compiling
258 with 'gcc -W'. Thanks to Matthias Andree
259 <matthias.andree@stud.uni-dortmund.de> for reporting this.
260
261 7. Fixed a small markup bug in the dump man page. Thanks to
262 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
263 patch.
264
265 8. Rewrote entirely the man pages using the tmac.an macro
266 package (Linux man page format) instead of the original BSD
267 format. They should be now cleaner and easier to modify.
268
269 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
270 ==================================================================
271
272 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
273 non Linux clients were misinterpreted. The description of the problem
274 (incompatible numbering in Linux mtio opcodes) is documented at
275 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
276 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
277 providing an excellent, cross-platform replacement for rmt in his
278 star package.
279
280 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
281 which caused restore to fail when the inode maps were not entirely
282 contained on the first volume (when using really small volumes or
283 when dumping a huge number of inodes).
284
285 3. Fixed a problem in dump, where files in subdirectories of directories
286 that have the nodump flag set (or being excluded with -e/-E) were
287 sometimes incorrectly dumped (instead of being excluded). The original
288 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
289 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
290 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
291 help testing the patch.
292
293 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
294 which makes one able to pipe the output of dump, by the net, to
295 a remote CD-burner server.
296
297 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
298 and use GNU's symbolic syntax over rmt instead of numerical values
299 to assure multiple platform compatibility.
300
301 6. Documented the -d option in restore.
302
303 7. Added a -v (verbose) mode to dump. For now it just prints the number
304 of the inode being dumped, but this could evolve in future versions
305 to include interesting debugging output.
306
307 8. Added a -o flag to restore, which automatically restores the current
308 directory permissions in -i or -x mode, without asking the operator
309 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
310 and Peter Samuel <peters@e-smith.com>.
311
312 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
313 ====================================================================
314
315 1. Fixed a bug in the QFA feature which could have caused
316 a bad tape positionning on restore (causing extra delays in
317 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
318
319 2. Added a small note in the dump man page specifying that
320 there should be no white space between the option letter and
321 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
322
323 3. Made restore work with older versions of the readline library,
324 by checking in configure for several extended symbols. Restore
325 can now be compiled with a readline as old as the 2.0 release
326 (though it may be a good idea to upgrade it to a more recent
327 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
328 reporting the build failures.
329
330 4. Fixed a performance problem with the QFA file creation in
331 dump, which made unnecessary seeks on the tape slowing down
332 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
333 reporting this issue.
334
335 5. Removed the inclusion of some kernel headers in the dump
336 source, which prevented the compile in some kernel/glibc
337 headers/architecture combination. Thanks to Bdale Garbee
338 <bdale@gag.com> for reporting the bug.
339
340 6. Added the appropriate error message when dump fails to
341 open the output file for writing. Thanks to Amith Varghese
342 <amithv@yahoo.com> for reporting this bug.
343
344 7. Made restore able to understand large Solaris ufsdump tapes
345 (containing inodes bigger than 4194304). Sun have introduced
346 an "extension" to the dump tape format when dealing with
347 those inodes, which was uncorrectly handled by Linux restore.
348 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
349 providing a test case.
350
351 8. Added the -m parameter to dump which optimises the output for
352 inodes having been changed but not modified since the last dump
353 ('changed' and 'modified' have the meaning defined in stat(2)).
354 For those inodes, dump will save only the metadata, instead of
355 saving the entire inode contents. Inodes which are either
356 directories or have been modified since the last dump are saved
357 in a regular way. Uses of this flag must be consistent, meaning
358 that either every dump in an incremental dump set have the flag,
359 or no one has it.
360
361 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
362 =======================================================================
363
364 1. Fixed behaviour of dump when exceeding resource limits
365 (SIGXFSZ treatment).
366
367 2. Added the -L flag to restore to allow the user to specify a
368 maximal allowed number of miscompares when using restore
369 with the -C option to check the backup.
370
371 3. Detailed the manual entry for the -N option of restore.
372
373 4. Added the -a flag to restore to make able doing unattended
374 restores in -i or -x mode (automatically walks through the
375 multiple dump volumes).
376
377 5. Extended the QFA mode to work with local files and/or
378 remote tapes and files. This way, restore can know in advance
379 the tape number and the offset for the inodes to extract and
380 can minimize the extraction time by seeking directly to the
381 good tape/offset.
382
383 6. Added the -A <archive> option to both dump and restore,
384 which makes dump to archive a dump table-of-contents in
385 the specified file to be used by restore to determine
386 whether a file is in the dump file that is being restored.
387 (the archive file syntax is also compatible with the
388 Solaris ufsdump generated one).
389
390 7. Small fix in restore making it able to read some (broken ?)
391 Solaris ufsdump tapes.
392
393 8. Fixed dump to correctly recognise the root filesystem when using
394 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
395 for reporting this bug.
396
397 9. Added the -P <file> option to restore to create a
398 Quick File Access file from an already made dump. Patch
399 contributed by Uwe Gohlke <uwe@ugsoft.de>.
400
401 10. Made restore compile and run on Solaris, making it a
402 possible replacement for the standard ufsrestore. Port was
403 contributed by Uwe Gohlke <uwe@ugsoft.de>.
404
405 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
406 =====================================================================
407
408 1. Added a set of backup scripts from Eugenio Diaz
409 <getnito@yahoo.com> in the examples section. It features
410 automatic (cron based) full and incremental dumping of
411 several filesystems on a separate filesystem.
412
413 2. Fixed a off-by-one miscalculation which disabled dumping
414 a one letter subdirectory. Thanks to Chris Siebenmann
415 <cks@utcc.utoronto.ca> for reporting the bug.
416
417 3. Fixed several restore bugs occuring when trying to
418 restore some missing files on the tape. Thanks to Chris
419 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
420
421 4. Fixed --with-ldopts configure argument passing, installing from
422 a separate object directory, makefile cleanups contributed
423 by <splite@purdue.edu>.
424
425 5. Fix a bug which could caused, in some conditions, the highest
426 number inode of a filesystem, to not be dumped. Many thanks
427 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
428 chase this bug.
429
430 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
431 =======================================================================
432
433 1. Added a mini howto from Patrick Walsh in the examples
434 directory.
435
436 2. Minor man pages syntax corrections. Thanks to
437 Chris Danis <screechco@home.com> for reporting the bugs.
438
439 3. Added a script from David B. Peterson <dave@toppledwagon.com>
440 to the examples section. It features dumping several
441 filesystems to a remote tape drive upon ssh.
442
443 4. Added a patch provided by Richard Jones <rich@annexia.org>
444 which allows BRADEMAX (number of read errors tolerated by
445 dump) to be adjusted using the -I option.
446
447 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
448 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
449 patch.
450
451 6. Add the -l option to restore to specify if, when doing a
452 remote restore, the file used to access the backup is a
453 regular file (the defaults being a tape drive). Restore needs
454 to know this information when reading a remote compressed
455 dump. Previously, this information was autodetected, but
456 the autodetection code fails (with ioctl: Inappropriate ioctl
457 for device) when using a non Linux remote box. Thanks to
458 many users and especially to Eros Albertazzi
459 <eros@lamel.bo.cnr.it> for reporting this.
460
461 7. Found a workaroung for the dump deadlock problem (3 childs
462 stuck in pause(), father in read()). The workaround seems
463 to work for me and several beta-testers. If it doesn't work
464 for you, please report back.
465
466 8. Updated the RPM spec file (BuildPrereq, URL etc).
467
468 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
469 ========================================================================
470
471 1. Fixed the permissions of a newly created QFA file by dump.
472
473 2. Cleaned up the source of dump (the external variables
474 definition was a complete mess, making possible to have
475 objects overlap).
476
477 3. Fixed restore to use the full tape volume path when doing
478 a compare (since it changes the working directory to the
479 filesystem being compared in the process).
480
481 4. Added the -q option to dump which makes dump abort
482 whenever it needs operator attention. It should be
483 easier to use dump in scripts with this option.
484
485 5. Detect the use of incompatible options to dump and
486 refuse them (like -a and -B options together).
487
488 6. Added bzip2 compression to dump/restore (use option -j level
489 to select it). Note that you will need a restore version
490 >= 0.4b24 in order to restore a bzip2 compressed dump.
491 The same warning as for the zlib compression applies:
492 the tape format of a bzip2 dump is not compatible with the
493 original BSD tape format.
494
495 7. Fixed a overflow problem in dump corrupting the dump when
496 very large files were encountered. Thanks to Vladimir Nadvornik
497 for the bug report.
498
499 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
500 kernel buffer/page cache before starting the dump, helping
501 a bit those who use dump on mounted filesystems. Thanks to
502 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
503 for this suggestion.
504
505 9. Updated the RPM spec file following the RedHat changes
506 (dynamically linked binaries now in /usr/sbin etc).
507
508 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
509 which enables restore to recognise multi volume compressed dumps
510 done on CD. Included his scripts for dump (which pipe the dump
511 output directly into cdrecord) and restore. There is now
512 possible to to backups to CD on the fly!
513
514 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
515 ===================================================================
516
517 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
518 Marcus Meissner (Caldera International Security Dept.).
519
520 2. Implement the Sun rmt extended protocol. Patch submitted
521 by Ian Gordon <iangordon@users.sourceforge.net>.
522
523 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
524 the linux kernel header. This ensures that dump always has the
525 latest version of this file. Patch submitted by
526 Andreas Dilger <adilger@turbolinux.com>.
527
528 4. Report any filesystem present in either /etc/fstab with a
529 positive passno or /etc/dumpdates in dump -w output.
530 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
531
532 5. Fixed the looping problem in dump introduced in the
533 previous version.
534
535 6. Changed the -B option of dump to limit the size of
536 _compressed_ output per volume if compression is on.
537 Patch contributed by Helmut Jarausch
538 <jarausch@igpm.rwth-aachen.de>. Note however that, since
539 it is impossible to predict the size of the compressed
540 data before doing the compression, the -B limit is a bit
541 conservative.
542
543 7. Fixed a bug in reading the operator typed file/tape path for
544 the next volume in restore.
545
546 8. Implemented a "-F script" option to restore which permits the
547 user to specify a script which will be launched at the
548 beginning of each tape, useful for automatic programming of
549 tape changers for example. See the restore man page for the
550 script parameters and return codes.
551
552 9. Small fix for the QFA routines provided by Uwe Gohlke
553 <uwe@ugsoft.de>, and some recommendations for QFA uses in
554 the man pages.
555
556 10. Fixed the multivolume restoring where making a mistake
557 to the 'Mount next tape' prompt caused several blocks to
558 be lost.
559
560 11. Enhanced the -e option of dump to take as a parameter a
561 comma separated list of inode numbers.
562
563 12. Added the -E option to dump which specify a file containing
564 inode numbers to exclude from the dump.
565
566 13. Fixed the compressed multi-volume dump + restore.
567
568 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
569 ==================================================================
570
571 1. Made dump report the number of blocks dumped per volume.
572 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
573
574 2. Fix a bug in dump where waiting too much at the 'change volumes'
575 question caused the volume to be rewritten. Thanks to
576 Graham Reed <greed@users.sourceforge.net> for reporting the
577 bug and providing a patch.
578
579 3. Added a compression option to dump, contributed by Jerry
580 Peters <gapeters@worldnet.att.net>.
581
582 WARNING: the compression works only on files/pipes and
583 drives supporting variable block size.
584
585 WARNING2: tapes created using the compression feature are
586 incompatible with the standard dump tape format, and a
587 version of restore >= 0.4b22 will be needed for extraction.
588
589 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
590 architectures. Thanks to Paul Slootman <paul@debian.org> for
591 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
592 it upstream.
593
594 5. Many cleanups (CPP defines, const char warnings, check of
595 ext2fs COMPAT flags, time_t cleanups, added libext2 version
596 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
597
598 6. Made --prefix option work in configure. All the install path
599 are now based on the configure parameters.
600
601 7. Added the Quick File Access mode in dump/restore, contributed
602 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
603 a file tape position for each inode, and this file is used by
604 restore (if called with parameter Q and the filename)
605 to directly position the tape at the file restore is currently
606 working on. This saves hours when restoring single files from
607 large backups, saves the tapes and the drive's head. Use
608 --enable-qfa option of configure to compile in the QFA support.
609
610 8. Added the possibility to dump several files and directories
611 in a single invocation of dump. Thanks to Uwe Gohlke
612 <uwe@ugsoft.de> for implementing this option.
613
614 9. Fixed the dumping and restoring of files with holes
615 (files ending with holes didn't get dumped or restored
616 correctly).
617
618 10. Fixed a socket descriptor leak in dump, which leaved opened
619 3 file descriptors per dump process (and there is one dump
620 process per tape).
621
622 11. Fixed dump large file system support, by explicit use of
623 open64/lseek64/etc functions (explicit use needed because
624 e2fsprogs libraries don't behave well when compiled with
625 FILE_OFFSET_BITS=64).
626
627 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
628 ======================================================================
629
630 1. Fixed some bugs in the dump -w|-W logic introduced by
631 the previous version. Thanks to Andreas Dilger
632 <adilger@turbolinux.com> for his help on this one.
633
634 2. Fixed again a compilation problem when using old e2fs
635 headers (filesystem label related). Thanks to many users
636 who reported this stupid error.
637
638 3. Fixed a build problem on old lib5 based systems dealing with
639 _PATH_MNTTAB being undefined. Thanks to John Adams
640 <johna@onevista.com> for reporting the bug.
641
642 4. Improved the error detection in restore when creating
643 the temporary files in TMPDIR. Now restore will corectly
644 report a 'no space left on device' error instead of
645 strange errors which could imply an archive corruption.
646 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
647 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
648
649 5. Added the throughput information in dump's progression
650 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
651 for the patch.
652
653 6. Use libext2fs's inode scanning routines, which are particularly
654 robust when dealing with errors (especially when having some
655 bad blocks on the filesystem). Many thanks to Colin
656 <colin@horizon.com> for reporting the bug, investigating
657 the issues, finding a workaround, writing the patch and
658 fully testing it... (of course, if this patch will break
659 anything, he is to blame for :-)).
660
661 7. Made dump and restore LFS aware. Dump can dump a filesystem
662 containing large files, generate a large file on output and
663 restore can restore them. This feature is not enabled by
664 default, use --enable-largefile option of configure to enable
665 it (you need to have a LFS aware glibc though). Thanks to
666 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
667 and to Theodore T'so <tytso@valinux.com> for his always
668 useful thoughts.
669
670 8. Made dump ask upon a tape write error if it should rewrite
671 the current volume (assume this is a bad tape) or if it should
672 assume an end-of-tape condition (useful for tape drives which
673 behaves badly at the end of the tape). Thanks to Andreas
674 Dilger <adilger@turbolinux.com> for the suggestion.
675
676 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
677 =======================================================================
678
679 1. Fixed a small compilation problem due to a change
680 in the definintion of the struct sigaction in
681 glibc 2.0 / libc5. Thanks to Gunther Schlegel
682 <schlegel@riege.de> for reporting the bug and to
683 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
684 a fix.
685
686 2. Modified the label and uuid analysis in order to be
687 self-contained (independant of kernel/libc headers). This
688 should fix the compile with older kernel/libc headers and
689 will preserve the functionality. Thanks to Bernhard Erdmann
690 <bernhard.erdmann@gmx.de> for reporting the bug.
691
692 3. The 'exclude inode' option, if applied to a directory
693 inode, excludes now correctly all the leaves of this
694 directory. Thanks to John R. Dennison
695 <gerdesas@users.sourceforge.net> for reporting the bug.
696
697 4. Fixed the '-e' option to disable the possibility
698 to exclude the root inode (which causes the dumps to
699 be unreadable by restore). Prevented array overflow
700 when multiple -e options are used.
701
702 5. Fixed dump to correctly interpret a filesystem argument
703 which is a mountpoint and it is not an absolute path
704 (as specified in the fstab). Thanks to Bernhard R. Erdmann
705 <be@berdmann.de> for reporting the bug.
706
707 6. Made dump able to backup files larger than 2 GB. Note that
708 dump still doesn't cope with files larger than 4 GB.
709
710 7. Restore the real uid and gid before invoking an external
711 RSH program (big hole when dump or restore is suid root!).
712
713 8. Get the values for the default tape device and the location
714 of fstab file from the system headers. Thanks to
715 Andreas Dilger <adilger@turbolinux.com> for the patch.
716
717 9. Made dump -w|-W report all recognized filesystems
718 present in either /etc/fstab or /etc/dumpdates, and present
719 the list in the same order as in fstab file. Thanks
720 to Andreas Dilger <adilger@turbolinux.com> for the patch.
721
722 10. Made dump's -a (automatic end of tape detection) the
723 default. Specifying one of -B, -c, -d or -s options will
724 override the EOM detection. Thanks to Andreas Dilger
725 <adilger@turbolinux.com> for the patch.
726
727 11. Save the ext2 filesystem label into the dump volume label.
728 Specifying a volume label on the command line (-L option)
729 will override this feature. Thanks to Andreas Dilger
730 <adilger@turbolinux.com> for the patch.
731
732 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
733 =====================================================================
734
735 1. Fixed the signal handling in dump (which I broke in 0.4b17)
736 which was causing several strange dump failures (dump
737 hanged or segmentation faults etc).
738
739 2. Specified the default blocksize in the dump man page.
740
741 3. Changed two info messages of restore to be written on stdout
742 instead of stderr in order to leave stderr only for errors
743 or warnings. Thanks to Stephen Atwell
744 <satwell@urbana.css.mot.com> for the suggestion.
745
746 4. Corrected an off by one calculation which prevented
747 dumping a directory having a 1 character name length.
748 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
749 for reporting the bug.
750
751 5. Reinforce dump in order to allow only level 0 and no
752 -u option when dumping a subdirectory, and document
753 this in the man page. Thanks to Bernhard Erdmann
754 <bernhard.erdmann@gmx.de> for reporting the bug.
755
756 6. Fixed a small harmless bug in restore which caused
757 in some conditions hard links to be restored several
758 times (therefore generation some warning messages).
759 Thanks to Kenneth Porter <shiva@well.com> for
760 reporting the bug.
761
762 7. Updated the RPM spec file to the latest RedHat version,
763 providing FHS packaging and other cosmetic changes.
764 You will need RPM version >= 3.0.5 in order to build the RPM.
765
766 8. Updated the configure script to check for libtermcap
767 before checking for libreadline, because we need this
768 library in order to compile the readline support.
769
770 9. Made dump understand the LABEL= and UUID= notation
771 both in /etc/fstab and on the command line. Note that
772 you will need the /proc filesystem in order to use
773 these notations. Thanks to Erik Troan <ewt@redhat.com>
774 for providing the patch.
775
776 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
777 ===================================================================
778
779 1. Fixed a potential buffer overflow in restore. Thanks
780 to Stan Bubrouski <satan@fastdial.net> for reporting
781 the bug.
782
783 2. Fixed a readline-related bug which prevented
784 'cat DUMPFILE | restore -i -f -' from working. Thanks
785 to Charles Karney <karney@users.sourceforge.net>
786 for the bug report.
787
788 3. Changed a few "panic" into "exit", causing restore to
789 be more stable against some attacks (like the last one
790 reported on Bugtraq, although the last version of restore
791 was not vulnerable - just dumped core). Thanks to
792 Andreas Hasenack <andreas@conectiva.com.br> for reporting
793 the bugs to me.
794
795 4. Removed the suid-root bit on dump and restore in the
796 default build (and generated RPMs). It should be safer
797 now. Users who need the suid-root capabilities in order
798 to make network backups should read first the man page
799 of dump and enable the suid bit manually.
800
801 5. Added -ltermcap to the compile parameters for restore
802 when using readline support, in order to make the compile
803 process work on some systems (SuSE ?). Thanks to
804 Patrik Schindler <poc@pocnet.net> for reporting the bug.
805
806 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
807 ====================================================================
808
809 1. The -F script is called now *only* at the end of a tape,
810 not at the end of the dump. Thanks to Christian Haul
811 <haul@informatik.tu-darmstadt.de> for the bug report.
812
813 Normally, the device name and the current volume number
814 are passed on the command line of the script. However,
815 if you want the old style script (with no arguments
816 passed on the command line), you can enable it in
817 configure with the --enable-oldstylefscript.
818
819 2. Use posix signal handling to preserve dump functionality
820 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
821 the patch.
822
823 3. Made the exit code of restore in case of a 'C'ompare
824 command reflect the result of the compare. An exit status
825 of 0 means the dump archive is correct, 1 means tape errors,
826 2 means that some files were modified. Thanks to Kenneth Porter
827 <shiva@well.com> for the suggestion.
828
829 4. Made (finally) quotes work in interactive restore.
830
831 5. Small fixes in order to allow dump to compile with a
832 really old e2fsprogs version. Thanks to Ian Zimmerman
833 <itz@speakeasy.org> for the bug report.
834
835 6. Add GNU readline capabilities to interactive restore.
836 Use configure's --enable-readline flag to enable this feature.
837 Thanks to Patrik Schindler <poc@pocnet.net> for the
838 suggestion.
839
840 7. Do the compare on the fly in restore 'C' mode (this will
841 allow not to exhaust the available /tmp space when
842 ccmparing large files). Thanks to Kenneth Porter
843 <shiva@well.com> for the suggestion.
844
845 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
846 ====================================================================
847
848 1. Fixed some several duplicate 'DUMP: DUMP:' in the
849 output of dump.
850
851 2. Corrected the estimation of blocks to dump. Note that
852 this is still wrong for large directory inodes, due
853 to the size of a BSD directory entry on the tape
854 (estimation is based on the size of the ext2 directory,
855 which is smaller because it doesn't contain the null
856 character at the end).
857
858 3. Made dump report the total number of MB written to
859 tape at the end of run. Thanks to W. Reilly Cooley
860 <wcooley@nakedape.cc> for the patch.
861
862 4. Added the -X option to restore giving the possibility
863 to read the names of the files to be extracted/listed
864 from a text file (in addition of the command line).
865 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
866 patch.
867
868 5. Added the device name and the current volume number
869 as arguments to the end of tape script (dump -F option).
870
871 6. Made the multi-volume dump work again (after having
872 broken it in 0.4b15).
873
874 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
875 ===================================================================
876
877 1. Added a prompt command in interactive restore mode. Thanks
878 to Andreas Dilger <adilger@home.com> for the patch.
879
880 2. Fixed a buffer overflow problem in dump (caused by
881 not checking the size of the filesystem parameter).
882 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
883 reporting this on Bugtraq (and to several dump users
884 who forwarded me his mail).
885
886 3. Added the '-F script' option to dump in order to
887 launch a script at the end of each tape (to be used
888 with a tape changer, or to notify the sysadmin by
889 pager etc.).
890
891 4. Fixed a bug in restore compare code caused by the changes
892 I made in 0.4b14.
893
894 5. Fixed the treatment of options using the old BSD syntax
895 in both dump and restore.
896
897 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
898 =======================================================================
899
900 1. Fixed a bug in dump which may have caused invalid deleted
901 directories to be dumped out if they were deleted after the
902 mapping pass. This could occure on active filesystem and lead
903 to heap corruption (causing dump malfunction in many possible ways).
904 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
905 bug and submitting the patch.
906
907 2. Fixed the handling of the filesystem parameter in dump. A
908 '/mnt/disk' parameter caused the disk contents to be dumped,
909 but a '/mnt/disk/' parameter caused the mountpoint directory
910 to be dumped (generally an empty directory).
911
912 3. Improved the output of dump in order to tell which directory
913 it is currently dumping (when dumping a subtree).
914
915 4. Added the '-e' exclude inode option to dump. Thanks to
916 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
917
918 5. Added a REPORTING-BUGS file in order to provide a guide
919 on how to correctly report a bug in dump/restore.
920
921 6. Fixed a restore problem when restoring a hard link to an inode
922 having the immutable or append-only attribute set. Thanks to
923 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
924
925 7. Fixed a compatibility problem between dumps made on little
926 endian machines (the format was correct) and big endian
927 machines (the format was incorrect). This fix break the
928 compatibility with the older dumps made on big endian
929 machines (sparc, m86k, ppc etc). For the first time in
930 linux dump's history (I believe), the dumps made by *BSD,
931 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
932 so interchangeable. Thanks to Rob Cermak
933 <cermak@ahab.rutgers.edu> for submitting the bug and
934 helping me test the fix.
935
936 8. Fixed the way dump reports the remaining percent/time, if
937 the number of blocks actually dumped exceeds the estimated
938 number of blocks. Thanks to Jean-Paul van der Jagt
939 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
940
941 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
942 ======================================================================
943
944 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
945 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
946
947 2. Removed the requirement to build the RPM as root from the
948 spec file. Thanks to Christian Weisgerber
949 <naddy@mips.rhein-neckar.de> for submitting this.
950
951 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
952 causing dump to block when dumping really huge filesystems.
953 Many thanks to Patrik Schindler <poc@pocnet.net> for
954 helping me find this bug.
955
956 4. Fixed the treatment for an interrupt signal when dump access
957 the remote tape through RSH. Thanks to Christian Weisgerber
958 <naddy@mips.rhein-neckar.de> for providing the patch.
959
960 5. Fixed a bug which was causing dump/restore to display
961 garbage characters instead of the remote host name.
962
963 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
964 =====================================================================
965
966 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
967 <kukuk@suse.de> for submitting the patch.
968
969 2. Fix for the exit code when using the size estimate option of
970 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
971 submitting the patch.
972
973 3. Handle EINTR in atomical reads/writes in dump, which was causing
974 dump to fail on some systems. Thanks to Eric Jergensen
975 <eric@dvns.com> for reporting the bug and submitting the patch.
976
977 4. Handle more than 16 characters for the device names in dumpdates.
978 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
979 tracking down the problem and proposing the solution.
980
981 5. Fixed a bug in dump which prevented the creation of the
982 dumpdates file when doing a 0-level dump without already
983 having a dumpdates file. Thanks to Patrik Schindler
984 <poc@pocnet.net> for reporting the bug.
985
986 6. Changed the way dump 'S' flag reports the size estimate
987 from number of blocks into bytes (making it compatible
988 with the Solaris version, and simplifying things for
989 amanda users). Thanks to Jason L Tibbitts III
990 <tibbs@math.uh.edu> for reporting the bug.
991
992 7. Fixed a compatibility problem in linux/alpha dump tape format.
993 Now the linux/alpha dump are (again) compatible with the
994 other dump formats. But this breaks compatibility with
995 older dumps made on alpha. Thanks to Mike Tibor
996 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
997
998 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
999 ======================================================================
1000
1001 1. Added a '--enable-kerberos' to configure.
1002
1003 2. Added a 'S' option to dump which determines the amount of space
1004 that is needed to perform the dump without actually doing it, similar
1005 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1006 <cermak@ahab.rutgers.edu>.
1007
1008 3. Added a 'M' multi-volume option to dump and restore which enables
1009 dumping to multiple files (useful when dumping to an ext2
1010 partition to make several dump files in order to bypass the 2GB
1011 file size limitation). The 'f' argument is treated as a prefix and
1012 the output files will be named <prefix>001, <prefix>002 etc. With
1013 the 'M' flag, restore automatically selects the right file without
1014 asking to enter a new tape each time.
1015
1016 4. Fixed a memory leak which was causing dump to grow very big
1017 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1018 Fearon <jasonf@netrider.org.au> for reporting the bug.
1019
1020 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1021 ======================================================================
1022
1023 1. Make configure test if the system glob routines support
1024 extended syntax (ALTDIRFUNC). If not, use the internal glob
1025 routines instead of system ones. Thanks to Bernhard Sadlowski
1026 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1027 and helping me resolve this and other minor libc5 compiling
1028 glitches.
1029
1030 2. Fix a problem when dumping a ext2fs with the 'filetype'
1031 feature enabled. Thanks to Patrick J. LoPresti
1032 <patl@cag.lcs.mit.edu> for reporting the bug and to
1033 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1034
1035 3. Made the nodump flag work on directories. A directory which
1036 has the nodump flag gets never dumped, regardless of its
1037 contents.
1038
1039 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1040 which allows dump on an active ext3 filesystem. However, this
1041 is a "quick and dirty" patch which enables backup of an ext3
1042 filesystem through the ext2 compatibility (by ignoring the
1043 NEEDS_RECOVERY bit). The journal file is not recognized and
1044 it is dumped (it should not).
1045
1046 5. Test the superblock compatibility flags when dumping, in order
1047 to be sure that we know how to deal with specific features.
1048
1049 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1050 ====================================================================
1051
1052 1. Use lchown instead of chown, fixing a possible security problem
1053 when restoring symlinks (a malicious user could use this
1054 to deliberately corrupt the ownership of important system files).
1055 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1056 this and providing the patch.
1057
1058 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1059 ====================================================================
1060
1061 1. Put dump sources under CVS, added Id tags in all files so
1062 one can use 'ident' on binary files.
1063
1064 2. Added the dump/restore version in the usage text so one can
1065 easily verify the version he is using.
1066
1067 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1068 a va_start/va_end problem on linux-ppc (always call va_start
1069 va_end in pairs each time we use a vararg function).
1070
1071 4. Added again the DT_* constants because old libc does not
1072 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1073 for submitting the bug report.
1074
1075 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1076 this should enable dumping big (huge) filesystems.
1077
1078 6. Added the RSH environment variable in order to be able to
1079 use a rsh replacement like ssh when doing remote backups (and
1080 bypass the security limitations of rcmd). Now you can do remote
1081 backups without being root (or making dump setuid root).
1082
1083 7. Modified again the way dumpdates works. For incremental dumps,
1084 we need to read dumpdates even if we are not using 'u' option.
1085 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1086 this should work.
1087
1088 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1089 ===================================================================
1090
1091 1. Removed the 'k' flag from the restore 'about' text if kerberos
1092 was not compiled in.
1093
1094 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1095 to them (fsetflags takes a char*, setflags an open fd!).
1096
1097 3. (f)setflags is called only if the flags aren't empty. If the
1098 file is a special file, a warning is printed, because changing
1099 flags implies opening the device. Normally, a special file
1100 should not have any flag... (Debian bug #29775, patch provided
1101 by Abhijit Dasgupta <abhijit@ans.net>).
1102
1103 4. Made possible to dump a file system not mentioned in /etc/fstab.
1104 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1105
1106 5. Changed the default behaviour to not create dumpdates
1107 unless 'u' option is specified. Removed the old "debian-patch"
1108 which provided the same thing. (Debian bug #38136, #33818).
1109
1110 6. Removed all those dump*announce, since they were getting old...
1111
1112 7. Added warning messages if dumpdates does not exist and
1113 when an inferior level dump does not exist (except for a level 0
1114 dump).
1115
1116 8. Debugged the glob calls in interactive mode: restore used a
1117 dirent struct which was different from the /usr/include/dirent.h
1118 one (this used to work, is it a glibc2 change?), so none of the
1119 compat glob (which used /usr/include/dirent.h) or the system glob
1120 worked. Restore use now the system dirent (and the system
1121 DT_* constants), which are compatible with BSD ones.
1122
1123 9. Added a configure flag (--with-dumpdatespath) to specify
1124 the location of dumpdates file. By default, it is
1125 /etc/dumpdates.
1126
1127 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1128 included the current date/version in man pages.
1129
1130 11. Corrected the estimation of remaining time when
1131 the operator doesn't change the tapes quickly enough. This
1132 was an old bug, I thought I corrected it, and discovered
1133 that in fact it was corrected in two different places, so
1134 the results canceled each other...
1135
1136 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1137 ===================================================================
1138
1139 1. Integrated multiple patches from RedHat, Debian and SuSE:
1140
1141 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1142 isn't specified.
1143 - several fixes in the man pages.
1144 - update the default tape device to /dev/st0.
1145 - many updates for Linux Alpha (byte ordering, size_t etc).
1146 - buffer overruns.
1147 - use environment variable for TMPDIR (instead of /tmp).
1148 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1149 - workaround egcs bug (RedHat bugs #4281 and #2989).
1150 - wire $(OPT) throughout Makefile's.
1151
1152 2. Upgrade the dump revision to 1, making possible to dump filesystems
1153 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1154
1155 3. Fix some compile warnings, prototype all functions.
1156
1157 4. Use glibc err/glob instead of internal compatibility
1158 routines (only if available).
1159
1160 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1161 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1162
1163 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1164 ======================================================================
1165
1166 1. Integrated the changes from FreeBSD-3.1-RELEASE
1167 (mostly bug fixes, buffer overruns, dump has now an "automatic
1168 tape length calculation" flag, dump/restore can use kerberos now
1169 (this is NOT tested), use environment variables for TAPE and
1170 RMT etc.).
1171
1172 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1173
1174 3. Corrected a bug in restore when using 'C' option with multi-volumes
1175 tapes (files splited accros two tapes give "size changed" errors
1176 when comparing).
1177
1178 4. Corrected the long standing bug when dumping multiple tapes.
1179 This works for me, needs further testing.
1180
1181 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1182 ====================================================================
1183
1184 1. Dump now runs correctly on kernels 2.1.x
1185 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1186
1187 Changes between versions 0.4b2 and 0.4b3
1188 ========================================
1189
1190 1. Use realpath() if available
1191
1192 2. Report statistics
1193
1194 Changes between versions 0.4b1 and 0.4b2
1195 ========================================
1196
1197 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1198 the patch)
1199
1200 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1201
1202 3. Fixed configure.in to correctly handle --enable-rmt
1203
1204 Changes between versions 0.3 and 0.4b1
1205 ======================================
1206
1207 1. Integrated the changes from 4.4BSD-Lite2
1208
1209 2. Integrated the patches from Debian and Red Hat
1210
1211 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1212
1213 4. Changed dump to use the Ext2fs library to get block addresses. This
1214 should solve the endianness problem on SparcLinux.
1215
1216 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1217 distribution's one) to use autoconf
1218
1219 6. Fixed a few minor bugs
1220
1221 Changes between versions 0.2e and 0.2f
1222 ======================================
1223
1224 1. Added the creation of named pipes (fifos) in restore.
1225
1226 2. Added the -N flag in the restore manual page.
1227
1228 3. Added the file kernel.patch which contains the llseek() optimization
1229 patch for 1.2.x kernels.
1230
1231 4. Fixed a bug in the restoration of symbolic links: owner and group were
1232 not restored.
1233
1234 5. Integrated some changes from FreeBSD 2.2.
1235
1236 6. Added a call to ftruncate() after restoring each file to restore
1237 correctly files ending by a hole.
1238
1239 Changes between versions 0.2d and 0.2e
1240 ======================================
1241
1242 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1243 with owner = root (0) and group = root/wheel/whatever (0).
1244
1245 Changes between versions 0.2c and 0.2d
1246 ======================================
1247
1248 1. Dump is now able to backup 2GB+ filesystems.
1249
1250 2. Dump and restore can now be linked as static binaries.
1251
1252 Changes between versions 0.2b and 0.2c
1253 ======================================
1254
1255 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1256
1257 Changes between versions 0.2a and 0.2b
1258 ======================================
1259
1260 1. Really fixed the bug that I should have corrected in 0.2a.
1261
1262 2. Enabled optimization again.
1263
1264 Changes between versions 0.2 and 0.2a
1265 =====================================
1266
1267 1. Disabled the optimization during compilation.
1268
1269 Changes between versions 0.1 and 0.2
1270 ====================================
1271
1272 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1273 the fs_type field (actually, I modified the file fstab.c to make it
1274 use the mntent functions).
1275
1276 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1277 made by dump should be readable by the BSD restore and backups made
1278 by the BSD dump should be readable by restore. Unfortunately, this
1279 means that the dump format has changed between version 0.1 and version
1280 0.2 :-(
1281
1282 3. Dump is now able to backup a subtree, it is no longer limited to whole
1283 filesystems like the BSD version.
1284
1285 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1286 than 2 GB.
1287
1288 Changes between versions 0.0 and 0.1
1289 ====================================
1290
1291 1. Now create links rdump and rrestore during the `make install' step.
1292
1293 2. Linux port specific bugs added to the manual pages
1294
1295 3. Incorrect estimation of the number of tapes blocks fixed when doing
1296 incremental backups.
1297
1298 4. Better ls-like format in restore in interactive mode.
