2
3 Changes between versions 0.4b35 and 0.4b36 (released ?????????????????)
4 =======================================================================
5
6 1. Fixed dump compilation with old gcc versions. Thanks to
7 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8
9 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
10 =======================================================================
11
12 1. Added a note in the dump man page saying that the default
13 blocksize can be 32 if -d is used with a high density argument.
14 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
15 for the patch.
16
17 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
18 LDFLAGS environment variables. Thanks to Arcady Genkin
19 <antipode@users.sourceforge.net> for reporting the bug.
20
21 3. Made -e/-E options of dump accept an unlimited number of inodes
22 to be excluded, rather than a hardcoded maximum. Thanks to
23 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
24
25 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
26 and -D_USE_BSD_SIGNAL defines in configure in order to solve
27 64bit build problems because quad_t is redifined with a
28 different signature. Thanks to Mike Harris <mharris@redhat.com>
29 for reporting this bug.
30
31 5. Made restore build on Solaris, making possible to
32 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
33 <uwe@ugsoft.de> for the patch.
34
35 6. Made an extension in the dump tape format capable of saving
36 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
37 wrote the extension and contributed the restore code back
38 into this codebase. The same extension mechanism will be
39 used in the future to save ACLs...
40
41 7. Made rmt work correctly with regard to QFA and local/remote
42 files and tapes. The remote access will however work only
43 when the dump provided rmt version is used. If you want to
44 use another rmt server, please do not use the QFA feature.
45 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
46
47 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
48 ====================================================================
49
50 1. Fixed the INSTALL file to reflect the actual install paths.
51 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
52 reporting the bug.
53
54 2. Fixed the configure script to only check for headers presence
55 instead of trying to compile them. This should fix issues
56 with old build environments. Thanks to Kari Lempiainen
57 <kari@funky.pp.fi> for reporting the bug.
58
59 3. Fixed restore to correctly ignore sockets when comparing
60 a dump (as socket cannot be properly restored anyway). Thanks
61 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
62
63 4. Fixed restore to correctly access the archive file (-A argument)
64 even when using a remote tape. Thanks to Fabrice Bellet
65 <fabrice@bellet.info> for reporting the bug.
66
67 5. Fixed (again) handling of long (largefile) seeks in rmt.
68 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
69 the bug.
70
71 6. Fixed restore corner case when dealing with large block sizes
72 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
73 <fabrice@bellet.info> for reporting the bug.
74
75 7. Fixed a bug preventing dump to access a filesystem having
76 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
77 for reporting the bug.
78
79 8. Made dump store dump dates using explicit timezones, fixing a
80 problem with incremental dumps if the timezone is modified
81 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
82 the bug report and the patch.
83
84 9. Fixed a bug encountered when dumping individual files (not full
85 filesystems or directories) and dangling symbolic links happen
86 to be in the list of files. For as far as dump is concerned,
87 dangling symbolic links are allowed, and are dumped as is.
88 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
89 bug and providing the fix.
90
91 10. Fixed open and creation modes and permissions for QFA and
92 table-of-contents files in dump and restore. Thanks to
93 Philippe Troin <phil@fifi.org> for the patch.
94
95 11. Fixed the archive file descriptor handling enabling it to be 0.
96 This can happen in some cases when shell redirections are used.
97 Thanks to Philippe Troin <phil@fifi.org> for the patch.
98
99 12. Delayed the opening of archive file until after suid had been
100 dropped (fixing a possible security issue if dump is suid).
101 Thanks to Philippe Troin <phil@fifi.org> for the patch.
102
103 13. Fixed the 'S' command handling in the rmt client part.
104 Thanks to Philippe Troin <phil@fifi.org> for the patch.
105
106 14. Modified the end-of-tape script handling to print out statistics
107 (and stop the timer) before launching the eot script. Also, the eot
108 script does not get run anymore when using -M (which makes sense) or
109 when multiple tapes are listed on the command line
110 (-f tape0,tape1,tapen) (which also makes sense).
111 Thanks to Philippe Troin <phil@fifi.org> for the patch.
112
113 15. Relicensed dump/restore under the 'revised' BSD license, as per
114 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
115
116 16. Added LZO compression to dump. This new compression method has
117 the advantage of being super fast, thus not killing tape streaming
118 on slow machines. Thanks to Helmut Jarausch
119 <jarausch@igpm.rwth-aachen.de> for the patch and to
120 Markus Oberhumer <markus@oberhumer.com> for giving special permission
121 to include his miniLZO project (GPL licensed) in dump/restore.
122
123 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
124 <ant@notatla.demon.co.uk> for reporting the bugs.
125
126 18. Added a special rmt version which can do encryption when writing
127 to tape. Read examples/encrypted_rmt/README for details on
128 how to enable and configure it. Thanks to Ken Lalonde
129 <ken@globalremit.com> for the patch.
130
131 19. Made dump work with 2.5 kernel end of tape early warning semantics.
132 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
133
134 20. Fixed a bug which caused dump -w|-W not to work anymore, because
135 the fs_freq and fs_passno fields in /etc/mtab are always set
136 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
137 reporting the bug.
138
139 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
140 =======================================================================
141
142 1. Added a note in the restore man page clarifying the question
143 'set the permissions on the current directory ?' asked by
144 restore at the end of treatment in -i and -x modes.
145
146 2. Fixed the endianess issues when reading compressed tapes.
147 Thanks to Dark Force <daq4th@users.sourceforge.net> for
148 reporting this bug and providing test cases.
149
150 3. Fixed the "ACL won't be dumped" warning message (which showed
151 an extra, unrelated error message). Thanks to Dragan Krnic
152 <dkrnic@lycos.com> for reporting this bug.
153
154 4. Made dump look first into /etc/mtab, then into /etc/fstab
155 when searching for filesystem paths. Also fixed some problems
156 caused by binding mounts or multiple block device mounts.
157 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
158 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
159 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
160 and #160305, Sourceforge bugs #618699 and #679832).
161
162 5. Made dump's -I option accept the value '0' meaning all the
163 read errors will be ignored. This can be useful when running
164 dump from unattended sessions (like cron jobs). Thanks to
165 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
166
167 6. Fixed the output of dump to indicate 'blocks' instead of
168 'tape blocks' in the various messages (blocks are always
169 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
170 made it clearly print the current blocksize at the start of
171 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
172 the suggestions.
173
174 7. Made rmt understand long (largefiles) seeks.
175
176 8. Fixed build with very old versions of libext2fs, where
177 EXT2_FT_* constants were undefined.
178
179 9. Made dump accept the dumpdates path on the command line
180 (-D file option) instead of using only the hardcoded one.
181 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
182 suggestion.
183
184 10. Enabled rmt, LFS, readline, QFA options by default in
185 ./configure. Updated the configure process (new versions
186 of config.guess, config.sub etc).
187
188 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
189 =======================================================================
190
191 1. Changed dump to use fcntl(F_SETLK) style locking instead
192 of flock() when locking the dumpdates file. With the old
193 locking scheme, a local user having read rights on the
194 dumpdates file could be able to do a Denial of Service attack
195 on dump. In order to lock the dumpdates file with the new
196 scheme, the user would need to have write access on the file.
197 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
198 reporting the bug (originally a bugtraq post).
199
200 2. Fixed interactive 'ls' which caused spurious errors warnings
201 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
202 <jorgen_ostling@users.sourceforge.net> for reporting this
203 bug.
204
205 3. Fixed dump's estimate when dealing with sparse inodes.
206
207 4. Modified dump to allow setting a blocksize bigger than 32kB
208 (raised the limit to 1024kB), because newer hardware needs
209 this for proper operation. Thanks to Dirk Traenapp
210 <dtraenapp@users.sourceforge.net> for reporting this.
211
212 5. Fixed a bug causing Dump to stop and report an error if an
213 inode number in the exclude file was followed by some amount
214 of whitespace. Thanks to Jeffrey Sofferin
215 <sofferin@users.sourceforge.net> for reporting this bug.
216
217 6. Fixed a bug which caused restore, in some particular cases,
218 to ask some 'scary' questions and leave a bunch of RSTTMP
219 directories behind when restoring incremental tapes. Thanks
220 to Philippe Troin <phil@fifi.org> for reporting this bug and
221 providing the test cases.
222
223 7. Changed the wording when inodes are excluded from dump:
224 replaced 'Added inode 7 to exclude list' with
225 'Excluding inode 7 (resize inode) from dump', as suggested
226 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
227
228 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
229 ===================================================================
230
231 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
232 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
233 <eros@lamel.bo.cnr.it> for reporting the bug.
234
235 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
236 ===================================================================
237
238 1. Made dump print out the ext2 logical block number in case of a read
239 error, which can be given as an argument to debugfs' ncheck command,
240 in order to find out the affected inode. Added note about this
241 usage in dump's man page.
242
243 2. Fixed a problem in restore when reading tapes written on big
244 endian machines with very old versions of dump. The patch was
245 contributed by George Helffrich <george@geology.bristol.ac.uk>.
246
247 3. Fixed the tape length calculation when using large tapes
248 and compression. Thanks to Georg Lippold
249 <g_lippold@sourceforge.net> for reporting the bug.
250
251 4. Added a new set of examples in dump_on_cd_2 directory, based
252 on dump_on_cd examples but somewhat enhanced, supporting DVD
253 media, and localized in english and german. Thanks to
254 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
255
256 5. Made dump save 32 bit UID/GID. Internally, this was achieved
257 by switching from the old BSD inode format to the new BSD
258 inode format, which means that the tape format was changed.
259 However, since all restore versions out there should
260 transparently support both inode formats, the change should
261 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
262 reporting the bug.
263
264 6. Fixed a lot of warnings in the code shown when compiling
265 with 'gcc -W'. Thanks to Matthias Andree
266 <matthias.andree@stud.uni-dortmund.de> for reporting this.
267
268 7. Fixed a small markup bug in the dump man page. Thanks to
269 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
270 patch.
271
272 8. Rewrote entirely the man pages using the tmac.an macro
273 package (Linux man page format) instead of the original BSD
274 format. They should be now cleaner and easier to modify.
275
276 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
277 ==================================================================
278
279 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
280 non Linux clients were misinterpreted. The description of the problem
281 (incompatible numbering in Linux mtio opcodes) is documented at
282 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
283 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
284 providing an excellent, cross-platform replacement for rmt in his
285 star package.
286
287 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
288 which caused restore to fail when the inode maps were not entirely
289 contained on the first volume (when using really small volumes or
290 when dumping a huge number of inodes).
291
292 3. Fixed a problem in dump, where files in subdirectories of directories
293 that have the nodump flag set (or being excluded with -e/-E) were
294 sometimes incorrectly dumped (instead of being excluded). The original
295 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
296 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
297 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
298 help testing the patch.
299
300 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
301 which makes one able to pipe the output of dump, by the net, to
302 a remote CD-burner server.
303
304 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
305 and use GNU's symbolic syntax over rmt instead of numerical values
306 to assure multiple platform compatibility.
307
308 6. Documented the -d option in restore.
309
310 7. Added a -v (verbose) mode to dump. For now it just prints the number
311 of the inode being dumped, but this could evolve in future versions
312 to include interesting debugging output.
313
314 8. Added a -o flag to restore, which automatically restores the current
315 directory permissions in -i or -x mode, without asking the operator
316 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
317 and Peter Samuel <peters@e-smith.com>.
318
319 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
320 ====================================================================
321
322 1. Fixed a bug in the QFA feature which could have caused
323 a bad tape positionning on restore (causing extra delays in
324 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
325
326 2. Added a small note in the dump man page specifying that
327 there should be no white space between the option letter and
328 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
329
330 3. Made restore work with older versions of the readline library,
331 by checking in configure for several extended symbols. Restore
332 can now be compiled with a readline as old as the 2.0 release
333 (though it may be a good idea to upgrade it to a more recent
334 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
335 reporting the build failures.
336
337 4. Fixed a performance problem with the QFA file creation in
338 dump, which made unnecessary seeks on the tape slowing down
339 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
340 reporting this issue.
341
342 5. Removed the inclusion of some kernel headers in the dump
343 source, which prevented the compile in some kernel/glibc
344 headers/architecture combination. Thanks to Bdale Garbee
345 <bdale@gag.com> for reporting the bug.
346
347 6. Added the appropriate error message when dump fails to
348 open the output file for writing. Thanks to Amith Varghese
349 <amithv@yahoo.com> for reporting this bug.
350
351 7. Made restore able to understand large Solaris ufsdump tapes
352 (containing inodes bigger than 4194304). Sun have introduced
353 an "extension" to the dump tape format when dealing with
354 those inodes, which was uncorrectly handled by Linux restore.
355 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
356 providing a test case.
357
358 8. Added the -m parameter to dump which optimises the output for
359 inodes having been changed but not modified since the last dump
360 ('changed' and 'modified' have the meaning defined in stat(2)).
361 For those inodes, dump will save only the metadata, instead of
362 saving the entire inode contents. Inodes which are either
363 directories or have been modified since the last dump are saved
364 in a regular way. Uses of this flag must be consistent, meaning
365 that either every dump in an incremental dump set have the flag,
366 or no one has it.
367
368 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
369 =======================================================================
370
371 1. Fixed behaviour of dump when exceeding resource limits
372 (SIGXFSZ treatment).
373
374 2. Added the -L flag to restore to allow the user to specify a
375 maximal allowed number of miscompares when using restore
376 with the -C option to check the backup.
377
378 3. Detailed the manual entry for the -N option of restore.
379
380 4. Added the -a flag to restore to make able doing unattended
381 restores in -i or -x mode (automatically walks through the
382 multiple dump volumes).
383
384 5. Extended the QFA mode to work with local files and/or
385 remote tapes and files. This way, restore can know in advance
386 the tape number and the offset for the inodes to extract and
387 can minimize the extraction time by seeking directly to the
388 good tape/offset.
389
390 6. Added the -A <archive> option to both dump and restore,
391 which makes dump to archive a dump table-of-contents in
392 the specified file to be used by restore to determine
393 whether a file is in the dump file that is being restored.
394 (the archive file syntax is also compatible with the
395 Solaris ufsdump generated one).
396
397 7. Small fix in restore making it able to read some (broken ?)
398 Solaris ufsdump tapes.
399
400 8. Fixed dump to correctly recognise the root filesystem when using
401 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
402 for reporting this bug.
403
404 9. Added the -P <file> option to restore to create a
405 Quick File Access file from an already made dump. Patch
406 contributed by Uwe Gohlke <uwe@ugsoft.de>.
407
408 10. Made restore compile and run on Solaris, making it a
409 possible replacement for the standard ufsrestore. Port was
410 contributed by Uwe Gohlke <uwe@ugsoft.de>.
411
412 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
413 =====================================================================
414
415 1. Added a set of backup scripts from Eugenio Diaz
416 <getnito@yahoo.com> in the examples section. It features
417 automatic (cron based) full and incremental dumping of
418 several filesystems on a separate filesystem.
419
420 2. Fixed a off-by-one miscalculation which disabled dumping
421 a one letter subdirectory. Thanks to Chris Siebenmann
422 <cks@utcc.utoronto.ca> for reporting the bug.
423
424 3. Fixed several restore bugs occuring when trying to
425 restore some missing files on the tape. Thanks to Chris
426 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
427
428 4. Fixed --with-ldopts configure argument passing, installing from
429 a separate object directory, makefile cleanups contributed
430 by <splite@purdue.edu>.
431
432 5. Fix a bug which could caused, in some conditions, the highest
433 number inode of a filesystem, to not be dumped. Many thanks
434 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
435 chase this bug.
436
437 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
438 =======================================================================
439
440 1. Added a mini howto from Patrick Walsh in the examples
441 directory.
442
443 2. Minor man pages syntax corrections. Thanks to
444 Chris Danis <screechco@home.com> for reporting the bugs.
445
446 3. Added a script from David B. Peterson <dave@toppledwagon.com>
447 to the examples section. It features dumping several
448 filesystems to a remote tape drive upon ssh.
449
450 4. Added a patch provided by Richard Jones <rich@annexia.org>
451 which allows BRADEMAX (number of read errors tolerated by
452 dump) to be adjusted using the -I option.
453
454 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
455 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
456 patch.
457
458 6. Add the -l option to restore to specify if, when doing a
459 remote restore, the file used to access the backup is a
460 regular file (the defaults being a tape drive). Restore needs
461 to know this information when reading a remote compressed
462 dump. Previously, this information was autodetected, but
463 the autodetection code fails (with ioctl: Inappropriate ioctl
464 for device) when using a non Linux remote box. Thanks to
465 many users and especially to Eros Albertazzi
466 <eros@lamel.bo.cnr.it> for reporting this.
467
468 7. Found a workaroung for the dump deadlock problem (3 childs
469 stuck in pause(), father in read()). The workaround seems
470 to work for me and several beta-testers. If it doesn't work
471 for you, please report back.
472
473 8. Updated the RPM spec file (BuildPrereq, URL etc).
474
475 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
476 ========================================================================
477
478 1. Fixed the permissions of a newly created QFA file by dump.
479
480 2. Cleaned up the source of dump (the external variables
481 definition was a complete mess, making possible to have
482 objects overlap).
483
484 3. Fixed restore to use the full tape volume path when doing
485 a compare (since it changes the working directory to the
486 filesystem being compared in the process).
487
488 4. Added the -q option to dump which makes dump abort
489 whenever it needs operator attention. It should be
490 easier to use dump in scripts with this option.
491
492 5. Detect the use of incompatible options to dump and
493 refuse them (like -a and -B options together).
494
495 6. Added bzip2 compression to dump/restore (use option -j level
496 to select it). Note that you will need a restore version
497 >= 0.4b24 in order to restore a bzip2 compressed dump.
498 The same warning as for the zlib compression applies:
499 the tape format of a bzip2 dump is not compatible with the
500 original BSD tape format.
501
502 7. Fixed a overflow problem in dump corrupting the dump when
503 very large files were encountered. Thanks to Vladimir Nadvornik
504 for the bug report.
505
506 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
507 kernel buffer/page cache before starting the dump, helping
508 a bit those who use dump on mounted filesystems. Thanks to
509 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
510 for this suggestion.
511
512 9. Updated the RPM spec file following the RedHat changes
513 (dynamically linked binaries now in /usr/sbin etc).
514
515 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
516 which enables restore to recognise multi volume compressed dumps
517 done on CD. Included his scripts for dump (which pipe the dump
518 output directly into cdrecord) and restore. There is now
519 possible to to backups to CD on the fly!
520
521 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
522 ===================================================================
523
524 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
525 Marcus Meissner (Caldera International Security Dept.).
526
527 2. Implement the Sun rmt extended protocol. Patch submitted
528 by Ian Gordon <iangordon@users.sourceforge.net>.
529
530 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
531 the linux kernel header. This ensures that dump always has the
532 latest version of this file. Patch submitted by
533 Andreas Dilger <adilger@turbolinux.com>.
534
535 4. Report any filesystem present in either /etc/fstab with a
536 positive passno or /etc/dumpdates in dump -w output.
537 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
538
539 5. Fixed the looping problem in dump introduced in the
540 previous version.
541
542 6. Changed the -B option of dump to limit the size of
543 _compressed_ output per volume if compression is on.
544 Patch contributed by Helmut Jarausch
545 <jarausch@igpm.rwth-aachen.de>. Note however that, since
546 it is impossible to predict the size of the compressed
547 data before doing the compression, the -B limit is a bit
548 conservative.
549
550 7. Fixed a bug in reading the operator typed file/tape path for
551 the next volume in restore.
552
553 8. Implemented a "-F script" option to restore which permits the
554 user to specify a script which will be launched at the
555 beginning of each tape, useful for automatic programming of
556 tape changers for example. See the restore man page for the
557 script parameters and return codes.
558
559 9. Small fix for the QFA routines provided by Uwe Gohlke
560 <uwe@ugsoft.de>, and some recommendations for QFA uses in
561 the man pages.
562
563 10. Fixed the multivolume restoring where making a mistake
564 to the 'Mount next tape' prompt caused several blocks to
565 be lost.
566
567 11. Enhanced the -e option of dump to take as a parameter a
568 comma separated list of inode numbers.
569
570 12. Added the -E option to dump which specify a file containing
571 inode numbers to exclude from the dump.
572
573 13. Fixed the compressed multi-volume dump + restore.
574
575 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
576 ==================================================================
577
578 1. Made dump report the number of blocks dumped per volume.
579 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
580
581 2. Fix a bug in dump where waiting too much at the 'change volumes'
582 question caused the volume to be rewritten. Thanks to
583 Graham Reed <greed@users.sourceforge.net> for reporting the
584 bug and providing a patch.
585
586 3. Added a compression option to dump, contributed by Jerry
587 Peters <gapeters@worldnet.att.net>.
588
589 WARNING: the compression works only on files/pipes and
590 drives supporting variable block size.
591
592 WARNING2: tapes created using the compression feature are
593 incompatible with the standard dump tape format, and a
594 version of restore >= 0.4b22 will be needed for extraction.
595
596 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
597 architectures. Thanks to Paul Slootman <paul@debian.org> for
598 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
599 it upstream.
600
601 5. Many cleanups (CPP defines, const char warnings, check of
602 ext2fs COMPAT flags, time_t cleanups, added libext2 version
603 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
604
605 6. Made --prefix option work in configure. All the install path
606 are now based on the configure parameters.
607
608 7. Added the Quick File Access mode in dump/restore, contributed
609 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
610 a file tape position for each inode, and this file is used by
611 restore (if called with parameter Q and the filename)
612 to directly position the tape at the file restore is currently
613 working on. This saves hours when restoring single files from
614 large backups, saves the tapes and the drive's head. Use
615 --enable-qfa option of configure to compile in the QFA support.
616
617 8. Added the possibility to dump several files and directories
618 in a single invocation of dump. Thanks to Uwe Gohlke
619 <uwe@ugsoft.de> for implementing this option.
620
621 9. Fixed the dumping and restoring of files with holes
622 (files ending with holes didn't get dumped or restored
623 correctly).
624
625 10. Fixed a socket descriptor leak in dump, which leaved opened
626 3 file descriptors per dump process (and there is one dump
627 process per tape).
628
629 11. Fixed dump large file system support, by explicit use of
630 open64/lseek64/etc functions (explicit use needed because
631 e2fsprogs libraries don't behave well when compiled with
632 FILE_OFFSET_BITS=64).
633
634 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
635 ======================================================================
636
637 1. Fixed some bugs in the dump -w|-W logic introduced by
638 the previous version. Thanks to Andreas Dilger
639 <adilger@turbolinux.com> for his help on this one.
640
641 2. Fixed again a compilation problem when using old e2fs
642 headers (filesystem label related). Thanks to many users
643 who reported this stupid error.
644
645 3. Fixed a build problem on old lib5 based systems dealing with
646 _PATH_MNTTAB being undefined. Thanks to John Adams
647 <johna@onevista.com> for reporting the bug.
648
649 4. Improved the error detection in restore when creating
650 the temporary files in TMPDIR. Now restore will corectly
651 report a 'no space left on device' error instead of
652 strange errors which could imply an archive corruption.
653 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
654 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
655
656 5. Added the throughput information in dump's progression
657 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
658 for the patch.
659
660 6. Use libext2fs's inode scanning routines, which are particularly
661 robust when dealing with errors (especially when having some
662 bad blocks on the filesystem). Many thanks to Colin
663 <colin@horizon.com> for reporting the bug, investigating
664 the issues, finding a workaround, writing the patch and
665 fully testing it... (of course, if this patch will break
666 anything, he is to blame for :-)).
667
668 7. Made dump and restore LFS aware. Dump can dump a filesystem
669 containing large files, generate a large file on output and
670 restore can restore them. This feature is not enabled by
671 default, use --enable-largefile option of configure to enable
672 it (you need to have a LFS aware glibc though). Thanks to
673 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
674 and to Theodore T'so <tytso@valinux.com> for his always
675 useful thoughts.
676
677 8. Made dump ask upon a tape write error if it should rewrite
678 the current volume (assume this is a bad tape) or if it should
679 assume an end-of-tape condition (useful for tape drives which
680 behaves badly at the end of the tape). Thanks to Andreas
681 Dilger <adilger@turbolinux.com> for the suggestion.
682
683 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
684 =======================================================================
685
686 1. Fixed a small compilation problem due to a change
687 in the definintion of the struct sigaction in
688 glibc 2.0 / libc5. Thanks to Gunther Schlegel
689 <schlegel@riege.de> for reporting the bug and to
690 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
691 a fix.
692
693 2. Modified the label and uuid analysis in order to be
694 self-contained (independant of kernel/libc headers). This
695 should fix the compile with older kernel/libc headers and
696 will preserve the functionality. Thanks to Bernhard Erdmann
697 <bernhard.erdmann@gmx.de> for reporting the bug.
698
699 3. The 'exclude inode' option, if applied to a directory
700 inode, excludes now correctly all the leaves of this
701 directory. Thanks to John R. Dennison
702 <gerdesas@users.sourceforge.net> for reporting the bug.
703
704 4. Fixed the '-e' option to disable the possibility
705 to exclude the root inode (which causes the dumps to
706 be unreadable by restore). Prevented array overflow
707 when multiple -e options are used.
708
709 5. Fixed dump to correctly interpret a filesystem argument
710 which is a mountpoint and it is not an absolute path
711 (as specified in the fstab). Thanks to Bernhard R. Erdmann
712 <be@berdmann.de> for reporting the bug.
713
714 6. Made dump able to backup files larger than 2 GB. Note that
715 dump still doesn't cope with files larger than 4 GB.
716
717 7. Restore the real uid and gid before invoking an external
718 RSH program (big hole when dump or restore is suid root!).
719
720 8. Get the values for the default tape device and the location
721 of fstab file from the system headers. Thanks to
722 Andreas Dilger <adilger@turbolinux.com> for the patch.
723
724 9. Made dump -w|-W report all recognized filesystems
725 present in either /etc/fstab or /etc/dumpdates, and present
726 the list in the same order as in fstab file. Thanks
727 to Andreas Dilger <adilger@turbolinux.com> for the patch.
728
729 10. Made dump's -a (automatic end of tape detection) the
730 default. Specifying one of -B, -c, -d or -s options will
731 override the EOM detection. Thanks to Andreas Dilger
732 <adilger@turbolinux.com> for the patch.
733
734 11. Save the ext2 filesystem label into the dump volume label.
735 Specifying a volume label on the command line (-L option)
736 will override this feature. Thanks to Andreas Dilger
737 <adilger@turbolinux.com> for the patch.
738
739 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
740 =====================================================================
741
742 1. Fixed the signal handling in dump (which I broke in 0.4b17)
743 which was causing several strange dump failures (dump
744 hanged or segmentation faults etc).
745
746 2. Specified the default blocksize in the dump man page.
747
748 3. Changed two info messages of restore to be written on stdout
749 instead of stderr in order to leave stderr only for errors
750 or warnings. Thanks to Stephen Atwell
751 <satwell@urbana.css.mot.com> for the suggestion.
752
753 4. Corrected an off by one calculation which prevented
754 dumping a directory having a 1 character name length.
755 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
756 for reporting the bug.
757
758 5. Reinforce dump in order to allow only level 0 and no
759 -u option when dumping a subdirectory, and document
760 this in the man page. Thanks to Bernhard Erdmann
761 <bernhard.erdmann@gmx.de> for reporting the bug.
762
763 6. Fixed a small harmless bug in restore which caused
764 in some conditions hard links to be restored several
765 times (therefore generation some warning messages).
766 Thanks to Kenneth Porter <shiva@well.com> for
767 reporting the bug.
768
769 7. Updated the RPM spec file to the latest RedHat version,
770 providing FHS packaging and other cosmetic changes.
771 You will need RPM version >= 3.0.5 in order to build the RPM.
772
773 8. Updated the configure script to check for libtermcap
774 before checking for libreadline, because we need this
775 library in order to compile the readline support.
776
777 9. Made dump understand the LABEL= and UUID= notation
778 both in /etc/fstab and on the command line. Note that
779 you will need the /proc filesystem in order to use
780 these notations. Thanks to Erik Troan <ewt@redhat.com>
781 for providing the patch.
782
783 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
784 ===================================================================
785
786 1. Fixed a potential buffer overflow in restore. Thanks
787 to Stan Bubrouski <satan@fastdial.net> for reporting
788 the bug.
789
790 2. Fixed a readline-related bug which prevented
791 'cat DUMPFILE | restore -i -f -' from working. Thanks
792 to Charles Karney <karney@users.sourceforge.net>
793 for the bug report.
794
795 3. Changed a few "panic" into "exit", causing restore to
796 be more stable against some attacks (like the last one
797 reported on Bugtraq, although the last version of restore
798 was not vulnerable - just dumped core). Thanks to
799 Andreas Hasenack <andreas@conectiva.com.br> for reporting
800 the bugs to me.
801
802 4. Removed the suid-root bit on dump and restore in the
803 default build (and generated RPMs). It should be safer
804 now. Users who need the suid-root capabilities in order
805 to make network backups should read first the man page
806 of dump and enable the suid bit manually.
807
808 5. Added -ltermcap to the compile parameters for restore
809 when using readline support, in order to make the compile
810 process work on some systems (SuSE ?). Thanks to
811 Patrik Schindler <poc@pocnet.net> for reporting the bug.
812
813 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
814 ====================================================================
815
816 1. The -F script is called now *only* at the end of a tape,
817 not at the end of the dump. Thanks to Christian Haul
818 <haul@informatik.tu-darmstadt.de> for the bug report.
819
820 Normally, the device name and the current volume number
821 are passed on the command line of the script. However,
822 if you want the old style script (with no arguments
823 passed on the command line), you can enable it in
824 configure with the --enable-oldstylefscript.
825
826 2. Use posix signal handling to preserve dump functionality
827 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
828 the patch.
829
830 3. Made the exit code of restore in case of a 'C'ompare
831 command reflect the result of the compare. An exit status
832 of 0 means the dump archive is correct, 1 means tape errors,
833 2 means that some files were modified. Thanks to Kenneth Porter
834 <shiva@well.com> for the suggestion.
835
836 4. Made (finally) quotes work in interactive restore.
837
838 5. Small fixes in order to allow dump to compile with a
839 really old e2fsprogs version. Thanks to Ian Zimmerman
840 <itz@speakeasy.org> for the bug report.
841
842 6. Add GNU readline capabilities to interactive restore.
843 Use configure's --enable-readline flag to enable this feature.
844 Thanks to Patrik Schindler <poc@pocnet.net> for the
845 suggestion.
846
847 7. Do the compare on the fly in restore 'C' mode (this will
848 allow not to exhaust the available /tmp space when
849 ccmparing large files). Thanks to Kenneth Porter
850 <shiva@well.com> for the suggestion.
851
852 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
853 ====================================================================
854
855 1. Fixed some several duplicate 'DUMP: DUMP:' in the
856 output of dump.
857
858 2. Corrected the estimation of blocks to dump. Note that
859 this is still wrong for large directory inodes, due
860 to the size of a BSD directory entry on the tape
861 (estimation is based on the size of the ext2 directory,
862 which is smaller because it doesn't contain the null
863 character at the end).
864
865 3. Made dump report the total number of MB written to
866 tape at the end of run. Thanks to W. Reilly Cooley
867 <wcooley@nakedape.cc> for the patch.
868
869 4. Added the -X option to restore giving the possibility
870 to read the names of the files to be extracted/listed
871 from a text file (in addition of the command line).
872 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
873 patch.
874
875 5. Added the device name and the current volume number
876 as arguments to the end of tape script (dump -F option).
877
878 6. Made the multi-volume dump work again (after having
879 broken it in 0.4b15).
880
881 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
882 ===================================================================
883
884 1. Added a prompt command in interactive restore mode. Thanks
885 to Andreas Dilger <adilger@home.com> for the patch.
886
887 2. Fixed a buffer overflow problem in dump (caused by
888 not checking the size of the filesystem parameter).
889 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
890 reporting this on Bugtraq (and to several dump users
891 who forwarded me his mail).
892
893 3. Added the '-F script' option to dump in order to
894 launch a script at the end of each tape (to be used
895 with a tape changer, or to notify the sysadmin by
896 pager etc.).
897
898 4. Fixed a bug in restore compare code caused by the changes
899 I made in 0.4b14.
900
901 5. Fixed the treatment of options using the old BSD syntax
902 in both dump and restore.
903
904 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
905 =======================================================================
906
907 1. Fixed a bug in dump which may have caused invalid deleted
908 directories to be dumped out if they were deleted after the
909 mapping pass. This could occure on active filesystem and lead
910 to heap corruption (causing dump malfunction in many possible ways).
911 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
912 bug and submitting the patch.
913
914 2. Fixed the handling of the filesystem parameter in dump. A
915 '/mnt/disk' parameter caused the disk contents to be dumped,
916 but a '/mnt/disk/' parameter caused the mountpoint directory
917 to be dumped (generally an empty directory).
918
919 3. Improved the output of dump in order to tell which directory
920 it is currently dumping (when dumping a subtree).
921
922 4. Added the '-e' exclude inode option to dump. Thanks to
923 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
924
925 5. Added a REPORTING-BUGS file in order to provide a guide
926 on how to correctly report a bug in dump/restore.
927
928 6. Fixed a restore problem when restoring a hard link to an inode
929 having the immutable or append-only attribute set. Thanks to
930 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
931
932 7. Fixed a compatibility problem between dumps made on little
933 endian machines (the format was correct) and big endian
934 machines (the format was incorrect). This fix break the
935 compatibility with the older dumps made on big endian
936 machines (sparc, m86k, ppc etc). For the first time in
937 linux dump's history (I believe), the dumps made by *BSD,
938 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
939 so interchangeable. Thanks to Rob Cermak
940 <cermak@ahab.rutgers.edu> for submitting the bug and
941 helping me test the fix.
942
943 8. Fixed the way dump reports the remaining percent/time, if
944 the number of blocks actually dumped exceeds the estimated
945 number of blocks. Thanks to Jean-Paul van der Jagt
946 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
947
948 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
949 ======================================================================
950
951 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
952 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
953
954 2. Removed the requirement to build the RPM as root from the
955 spec file. Thanks to Christian Weisgerber
956 <naddy@mips.rhein-neckar.de> for submitting this.
957
958 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
959 causing dump to block when dumping really huge filesystems.
960 Many thanks to Patrik Schindler <poc@pocnet.net> for
961 helping me find this bug.
962
963 4. Fixed the treatment for an interrupt signal when dump access
964 the remote tape through RSH. Thanks to Christian Weisgerber
965 <naddy@mips.rhein-neckar.de> for providing the patch.
966
967 5. Fixed a bug which was causing dump/restore to display
968 garbage characters instead of the remote host name.
969
970 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
971 =====================================================================
972
973 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
974 <kukuk@suse.de> for submitting the patch.
975
976 2. Fix for the exit code when using the size estimate option of
977 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
978 submitting the patch.
979
980 3. Handle EINTR in atomical reads/writes in dump, which was causing
981 dump to fail on some systems. Thanks to Eric Jergensen
982 <eric@dvns.com> for reporting the bug and submitting the patch.
983
984 4. Handle more than 16 characters for the device names in dumpdates.
985 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
986 tracking down the problem and proposing the solution.
987
988 5. Fixed a bug in dump which prevented the creation of the
989 dumpdates file when doing a 0-level dump without already
990 having a dumpdates file. Thanks to Patrik Schindler
991 <poc@pocnet.net> for reporting the bug.
992
993 6. Changed the way dump 'S' flag reports the size estimate
994 from number of blocks into bytes (making it compatible
995 with the Solaris version, and simplifying things for
996 amanda users). Thanks to Jason L Tibbitts III
997 <tibbs@math.uh.edu> for reporting the bug.
998
999 7. Fixed a compatibility problem in linux/alpha dump tape format.
1000 Now the linux/alpha dump are (again) compatible with the
1001 other dump formats. But this breaks compatibility with
1002 older dumps made on alpha. Thanks to Mike Tibor
1003 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1004
1005 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1006 ======================================================================
1007
1008 1. Added a '--enable-kerberos' to configure.
1009
1010 2. Added a 'S' option to dump which determines the amount of space
1011 that is needed to perform the dump without actually doing it, similar
1012 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1013 <cermak@ahab.rutgers.edu>.
1014
1015 3. Added a 'M' multi-volume option to dump and restore which enables
1016 dumping to multiple files (useful when dumping to an ext2
1017 partition to make several dump files in order to bypass the 2GB
1018 file size limitation). The 'f' argument is treated as a prefix and
1019 the output files will be named <prefix>001, <prefix>002 etc. With
1020 the 'M' flag, restore automatically selects the right file without
1021 asking to enter a new tape each time.
1022
1023 4. Fixed a memory leak which was causing dump to grow very big
1024 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1025 Fearon <jasonf@netrider.org.au> for reporting the bug.
1026
1027 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1028 ======================================================================
1029
1030 1. Make configure test if the system glob routines support
1031 extended syntax (ALTDIRFUNC). If not, use the internal glob
1032 routines instead of system ones. Thanks to Bernhard Sadlowski
1033 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1034 and helping me resolve this and other minor libc5 compiling
1035 glitches.
1036
1037 2. Fix a problem when dumping a ext2fs with the 'filetype'
1038 feature enabled. Thanks to Patrick J. LoPresti
1039 <patl@cag.lcs.mit.edu> for reporting the bug and to
1040 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1041
1042 3. Made the nodump flag work on directories. A directory which
1043 has the nodump flag gets never dumped, regardless of its
1044 contents.
1045
1046 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1047 which allows dump on an active ext3 filesystem. However, this
1048 is a "quick and dirty" patch which enables backup of an ext3
1049 filesystem through the ext2 compatibility (by ignoring the
1050 NEEDS_RECOVERY bit). The journal file is not recognized and
1051 it is dumped (it should not).
1052
1053 5. Test the superblock compatibility flags when dumping, in order
1054 to be sure that we know how to deal with specific features.
1055
1056 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1057 ====================================================================
1058
1059 1. Use lchown instead of chown, fixing a possible security problem
1060 when restoring symlinks (a malicious user could use this
1061 to deliberately corrupt the ownership of important system files).
1062 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1063 this and providing the patch.
1064
1065 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1066 ====================================================================
1067
1068 1. Put dump sources under CVS, added Id tags in all files so
1069 one can use 'ident' on binary files.
1070
1071 2. Added the dump/restore version in the usage text so one can
1072 easily verify the version he is using.
1073
1074 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1075 a va_start/va_end problem on linux-ppc (always call va_start
1076 va_end in pairs each time we use a vararg function).
1077
1078 4. Added again the DT_* constants because old libc does not
1079 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1080 for submitting the bug report.
1081
1082 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1083 this should enable dumping big (huge) filesystems.
1084
1085 6. Added the RSH environment variable in order to be able to
1086 use a rsh replacement like ssh when doing remote backups (and
1087 bypass the security limitations of rcmd). Now you can do remote
1088 backups without being root (or making dump setuid root).
1089
1090 7. Modified again the way dumpdates works. For incremental dumps,
1091 we need to read dumpdates even if we are not using 'u' option.
1092 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1093 this should work.
1094
1095 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1096 ===================================================================
1097
1098 1. Removed the 'k' flag from the restore 'about' text if kerberos
1099 was not compiled in.
1100
1101 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1102 to them (fsetflags takes a char*, setflags an open fd!).
1103
1104 3. (f)setflags is called only if the flags aren't empty. If the
1105 file is a special file, a warning is printed, because changing
1106 flags implies opening the device. Normally, a special file
1107 should not have any flag... (Debian bug #29775, patch provided
1108 by Abhijit Dasgupta <abhijit@ans.net>).
1109
1110 4. Made possible to dump a file system not mentioned in /etc/fstab.
1111 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1112
1113 5. Changed the default behaviour to not create dumpdates
1114 unless 'u' option is specified. Removed the old "debian-patch"
1115 which provided the same thing. (Debian bug #38136, #33818).
1116
1117 6. Removed all those dump*announce, since they were getting old...
1118
1119 7. Added warning messages if dumpdates does not exist and
1120 when an inferior level dump does not exist (except for a level 0
1121 dump).
1122
1123 8. Debugged the glob calls in interactive mode: restore used a
1124 dirent struct which was different from the /usr/include/dirent.h
1125 one (this used to work, is it a glibc2 change?), so none of the
1126 compat glob (which used /usr/include/dirent.h) or the system glob
1127 worked. Restore use now the system dirent (and the system
1128 DT_* constants), which are compatible with BSD ones.
1129
1130 9. Added a configure flag (--with-dumpdatespath) to specify
1131 the location of dumpdates file. By default, it is
1132 /etc/dumpdates.
1133
1134 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1135 included the current date/version in man pages.
1136
1137 11. Corrected the estimation of remaining time when
1138 the operator doesn't change the tapes quickly enough. This
1139 was an old bug, I thought I corrected it, and discovered
1140 that in fact it was corrected in two different places, so
1141 the results canceled each other...
1142
1143 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1144 ===================================================================
1145
1146 1. Integrated multiple patches from RedHat, Debian and SuSE:
1147
1148 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1149 isn't specified.
1150 - several fixes in the man pages.
1151 - update the default tape device to /dev/st0.
1152 - many updates for Linux Alpha (byte ordering, size_t etc).
1153 - buffer overruns.
1154 - use environment variable for TMPDIR (instead of /tmp).
1155 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1156 - workaround egcs bug (RedHat bugs #4281 and #2989).
1157 - wire $(OPT) throughout Makefile's.
1158
1159 2. Upgrade the dump revision to 1, making possible to dump filesystems
1160 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1161
1162 3. Fix some compile warnings, prototype all functions.
1163
1164 4. Use glibc err/glob instead of internal compatibility
1165 routines (only if available).
1166
1167 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1168 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1169
1170 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1171 ======================================================================
1172
1173 1. Integrated the changes from FreeBSD-3.1-RELEASE
1174 (mostly bug fixes, buffer overruns, dump has now an "automatic
1175 tape length calculation" flag, dump/restore can use kerberos now
1176 (this is NOT tested), use environment variables for TAPE and
1177 RMT etc.).
1178
1179 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1180
1181 3. Corrected a bug in restore when using 'C' option with multi-volumes
1182 tapes (files splited accros two tapes give "size changed" errors
1183 when comparing).
1184
1185 4. Corrected the long standing bug when dumping multiple tapes.
1186 This works for me, needs further testing.
1187
1188 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1189 ====================================================================
1190
1191 1. Dump now runs correctly on kernels 2.1.x
1192 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1193
1194 Changes between versions 0.4b2 and 0.4b3
1195 ========================================
1196
1197 1. Use realpath() if available
1198
1199 2. Report statistics
1200
1201 Changes between versions 0.4b1 and 0.4b2
1202 ========================================
1203
1204 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1205 the patch)
1206
1207 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1208
1209 3. Fixed configure.in to correctly handle --enable-rmt
1210
1211 Changes between versions 0.3 and 0.4b1
1212 ======================================
1213
1214 1. Integrated the changes from 4.4BSD-Lite2
1215
1216 2. Integrated the patches from Debian and Red Hat
1217
1218 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1219
1220 4. Changed dump to use the Ext2fs library to get block addresses. This
1221 should solve the endianness problem on SparcLinux.
1222
1223 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1224 distribution's one) to use autoconf
1225
1226 6. Fixed a few minor bugs
1227
1228 Changes between versions 0.2e and 0.2f
1229 ======================================
1230
1231 1. Added the creation of named pipes (fifos) in restore.
1232
1233 2. Added the -N flag in the restore manual page.
1234
1235 3. Added the file kernel.patch which contains the llseek() optimization
1236 patch for 1.2.x kernels.
1237
1238 4. Fixed a bug in the restoration of symbolic links: owner and group were
1239 not restored.
1240
1241 5. Integrated some changes from FreeBSD 2.2.
1242
1243 6. Added a call to ftruncate() after restoring each file to restore
1244 correctly files ending by a hole.
1245
1246 Changes between versions 0.2d and 0.2e
1247 ======================================
1248
1249 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1250 with owner = root (0) and group = root/wheel/whatever (0).
1251
1252 Changes between versions 0.2c and 0.2d
1253 ======================================
1254
1255 1. Dump is now able to backup 2GB+ filesystems.
1256
1257 2. Dump and restore can now be linked as static binaries.
1258
1259 Changes between versions 0.2b and 0.2c
1260 ======================================
1261
1262 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1263
1264 Changes between versions 0.2a and 0.2b
1265 ======================================
1266
1267 1. Really fixed the bug that I should have corrected in 0.2a.
1268
1269 2. Enabled optimization again.
1270
1271 Changes between versions 0.2 and 0.2a
1272 =====================================
1273
1274 1. Disabled the optimization during compilation.
1275
1276 Changes between versions 0.1 and 0.2
1277 ====================================
1278
1279 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1280 the fs_type field (actually, I modified the file fstab.c to make it
1281 use the mntent functions).
1282
1283 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1284 made by dump should be readable by the BSD restore and backups made
1285 by the BSD dump should be readable by restore. Unfortunately, this
1286 means that the dump format has changed between version 0.1 and version
1287 0.2 :-(
1288
1289 3. Dump is now able to backup a subtree, it is no longer limited to whole
1290 filesystems like the BSD version.
1291
1292 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1293 than 2 GB.
1294
1295 Changes between versions 0.0 and 0.1
1296 ====================================
1297
1298 1. Now create links rdump and rrestore during the `make install' step.
1299
1300 2. Linux port specific bugs added to the manual pages
1301
1302 3. Incorrect estimation of the number of tapes blocks fixed when doing
1303 incremental backups.
1304
1305 4. Better ls-like format in restore in interactive mode.
