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 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
10 when compiling against a recent glibc version.
11
12 3. Fixed a bug in restore preventing the read of a dump tape
13 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
14 <phiggins@transzap.com> for reporting the bug and providing
15 the test case.
16
17 4. Changed dump to enable the creation of volumes of different
18 sizes in a single run (make -B accept a list of values).
19 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
20
21 5. Use the glibc provided minor() and major() macros instead
22 of our own bitmask implementation. This should be safe for
23 when the major/minor namespace will migrate to 32 bits.
24 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
25 the bug.
26
27 6. Made explicit in the dump man page that dump will not create
28 a remote file, it will only write to an already existing one.
29
30 7. Another try at making size estimates better again.
31
32 8. Put back the inconditional running of the end-of-tape
33 script which was changed in 0.434 to be run only when -M
34 or multiple -f were NOT specified. Some users rely on this
35 feature even when it is combined with -M/-f.
36
37 9. Fixed restore when restoring huge backups (where rstdir...
38 temporary files are over 2GB). Thanks to
39 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
40 debugging the issue and making the patch.
41
42 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
43 =======================================================================
44
45 1. Added a note in the dump man page saying that the default
46 blocksize can be 32 if -d is used with a high density argument.
47 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
48 for the patch.
49
50 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
51 LDFLAGS environment variables. Thanks to Arcady Genkin
52 <antipode@users.sourceforge.net> for reporting the bug.
53
54 3. Made -e/-E options of dump accept an unlimited number of inodes
55 to be excluded, rather than a hardcoded maximum. Thanks to
56 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
57
58 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
59 and -D_USE_BSD_SIGNAL defines in configure in order to solve
60 64bit build problems because quad_t is redifined with a
61 different signature. Thanks to Mike Harris <mharris@redhat.com>
62 for reporting this bug.
63
64 5. Made restore build on Solaris, making possible to
65 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
66 <uwe@ugsoft.de> for the patch.
67
68 6. Made an extension in the dump tape format capable of saving
69 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
70 wrote the extension and contributed the restore code back
71 into this codebase. The same extension mechanism will be
72 used in the future to save ACLs...
73
74 7. Made rmt work correctly with regard to QFA and local/remote
75 files and tapes. The remote access will however work only
76 when the dump provided rmt version is used. If you want to
77 use another rmt server, please do not use the QFA feature.
78 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
79
80 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
81 ====================================================================
82
83 1. Fixed the INSTALL file to reflect the actual install paths.
84 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
85 reporting the bug.
86
87 2. Fixed the configure script to only check for headers presence
88 instead of trying to compile them. This should fix issues
89 with old build environments. Thanks to Kari Lempiainen
90 <kari@funky.pp.fi> for reporting the bug.
91
92 3. Fixed restore to correctly ignore sockets when comparing
93 a dump (as socket cannot be properly restored anyway). Thanks
94 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
95
96 4. Fixed restore to correctly access the archive file (-A argument)
97 even when using a remote tape. Thanks to Fabrice Bellet
98 <fabrice@bellet.info> for reporting the bug.
99
100 5. Fixed (again) handling of long (largefile) seeks in rmt.
101 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
102 the bug.
103
104 6. Fixed restore corner case when dealing with large block sizes
105 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
106 <fabrice@bellet.info> for reporting the bug.
107
108 7. Fixed a bug preventing dump to access a filesystem having
109 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
110 for reporting the bug.
111
112 8. Made dump store dump dates using explicit timezones, fixing a
113 problem with incremental dumps if the timezone is modified
114 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
115 the bug report and the patch.
116
117 9. Fixed a bug encountered when dumping individual files (not full
118 filesystems or directories) and dangling symbolic links happen
119 to be in the list of files. For as far as dump is concerned,
120 dangling symbolic links are allowed, and are dumped as is.
121 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
122 bug and providing the fix.
123
124 10. Fixed open and creation modes and permissions for QFA and
125 table-of-contents files in dump and restore. Thanks to
126 Philippe Troin <phil@fifi.org> for the patch.
127
128 11. Fixed the archive file descriptor handling enabling it to be 0.
129 This can happen in some cases when shell redirections are used.
130 Thanks to Philippe Troin <phil@fifi.org> for the patch.
131
132 12. Delayed the opening of archive file until after suid had been
133 dropped (fixing a possible security issue if dump is suid).
134 Thanks to Philippe Troin <phil@fifi.org> for the patch.
135
136 13. Fixed the 'S' command handling in the rmt client part.
137 Thanks to Philippe Troin <phil@fifi.org> for the patch.
138
139 14. Modified the end-of-tape script handling to print out statistics
140 (and stop the timer) before launching the eot script. Also, the eot
141 script does not get run anymore when using -M (which makes sense) or
142 when multiple tapes are listed on the command line
143 (-f tape0,tape1,tapen) (which also makes sense).
144 Thanks to Philippe Troin <phil@fifi.org> for the patch.
145
146 15. Relicensed dump/restore under the 'revised' BSD license, as per
147 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
148
149 16. Added LZO compression to dump. This new compression method has
150 the advantage of being super fast, thus not killing tape streaming
151 on slow machines. Thanks to Helmut Jarausch
152 <jarausch@igpm.rwth-aachen.de> for the patch and to
153 Markus Oberhumer <markus@oberhumer.com> for giving special permission
154 to include his miniLZO project (GPL licensed) in dump/restore.
155
156 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
157 <ant@notatla.demon.co.uk> for reporting the bugs.
158
159 18. Added a special rmt version which can do encryption when writing
160 to tape. Read examples/encrypted_rmt/README for details on
161 how to enable and configure it. Thanks to Ken Lalonde
162 <ken@globalremit.com> for the patch.
163
164 19. Made dump work with 2.5 kernel end of tape early warning semantics.
165 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
166
167 20. Fixed a bug which caused dump -w|-W not to work anymore, because
168 the fs_freq and fs_passno fields in /etc/mtab are always set
169 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
170 reporting the bug.
171
172 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
173 =======================================================================
174
175 1. Added a note in the restore man page clarifying the question
176 'set the permissions on the current directory ?' asked by
177 restore at the end of treatment in -i and -x modes.
178
179 2. Fixed the endianess issues when reading compressed tapes.
180 Thanks to Dark Force <daq4th@users.sourceforge.net> for
181 reporting this bug and providing test cases.
182
183 3. Fixed the "ACL won't be dumped" warning message (which showed
184 an extra, unrelated error message). Thanks to Dragan Krnic
185 <dkrnic@lycos.com> for reporting this bug.
186
187 4. Made dump look first into /etc/mtab, then into /etc/fstab
188 when searching for filesystem paths. Also fixed some problems
189 caused by binding mounts or multiple block device mounts.
190 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
191 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
192 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
193 and #160305, Sourceforge bugs #618699 and #679832).
194
195 5. Made dump's -I option accept the value '0' meaning all the
196 read errors will be ignored. This can be useful when running
197 dump from unattended sessions (like cron jobs). Thanks to
198 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
199
200 6. Fixed the output of dump to indicate 'blocks' instead of
201 'tape blocks' in the various messages (blocks are always
202 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
203 made it clearly print the current blocksize at the start of
204 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
205 the suggestions.
206
207 7. Made rmt understand long (largefiles) seeks.
208
209 8. Fixed build with very old versions of libext2fs, where
210 EXT2_FT_* constants were undefined.
211
212 9. Made dump accept the dumpdates path on the command line
213 (-D file option) instead of using only the hardcoded one.
214 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
215 suggestion.
216
217 10. Enabled rmt, LFS, readline, QFA options by default in
218 ./configure. Updated the configure process (new versions
219 of config.guess, config.sub etc).
220
221 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
222 =======================================================================
223
224 1. Changed dump to use fcntl(F_SETLK) style locking instead
225 of flock() when locking the dumpdates file. With the old
226 locking scheme, a local user having read rights on the
227 dumpdates file could be able to do a Denial of Service attack
228 on dump. In order to lock the dumpdates file with the new
229 scheme, the user would need to have write access on the file.
230 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
231 reporting the bug (originally a bugtraq post).
232
233 2. Fixed interactive 'ls' which caused spurious errors warnings
234 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
235 <jorgen_ostling@users.sourceforge.net> for reporting this
236 bug.
237
238 3. Fixed dump's estimate when dealing with sparse inodes.
239
240 4. Modified dump to allow setting a blocksize bigger than 32kB
241 (raised the limit to 1024kB), because newer hardware needs
242 this for proper operation. Thanks to Dirk Traenapp
243 <dtraenapp@users.sourceforge.net> for reporting this.
244
245 5. Fixed a bug causing Dump to stop and report an error if an
246 inode number in the exclude file was followed by some amount
247 of whitespace. Thanks to Jeffrey Sofferin
248 <sofferin@users.sourceforge.net> for reporting this bug.
249
250 6. Fixed a bug which caused restore, in some particular cases,
251 to ask some 'scary' questions and leave a bunch of RSTTMP
252 directories behind when restoring incremental tapes. Thanks
253 to Philippe Troin <phil@fifi.org> for reporting this bug and
254 providing the test cases.
255
256 7. Changed the wording when inodes are excluded from dump:
257 replaced 'Added inode 7 to exclude list' with
258 'Excluding inode 7 (resize inode) from dump', as suggested
259 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
260
261 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
262 ===================================================================
263
264 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
265 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
266 <eros@lamel.bo.cnr.it> for reporting the bug.
267
268 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
269 ===================================================================
270
271 1. Made dump print out the ext2 logical block number in case of a read
272 error, which can be given as an argument to debugfs' ncheck command,
273 in order to find out the affected inode. Added note about this
274 usage in dump's man page.
275
276 2. Fixed a problem in restore when reading tapes written on big
277 endian machines with very old versions of dump. The patch was
278 contributed by George Helffrich <george@geology.bristol.ac.uk>.
279
280 3. Fixed the tape length calculation when using large tapes
281 and compression. Thanks to Georg Lippold
282 <g_lippold@sourceforge.net> for reporting the bug.
283
284 4. Added a new set of examples in dump_on_cd_2 directory, based
285 on dump_on_cd examples but somewhat enhanced, supporting DVD
286 media, and localized in english and german. Thanks to
287 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
288
289 5. Made dump save 32 bit UID/GID. Internally, this was achieved
290 by switching from the old BSD inode format to the new BSD
291 inode format, which means that the tape format was changed.
292 However, since all restore versions out there should
293 transparently support both inode formats, the change should
294 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
295 reporting the bug.
296
297 6. Fixed a lot of warnings in the code shown when compiling
298 with 'gcc -W'. Thanks to Matthias Andree
299 <matthias.andree@stud.uni-dortmund.de> for reporting this.
300
301 7. Fixed a small markup bug in the dump man page. Thanks to
302 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
303 patch.
304
305 8. Rewrote entirely the man pages using the tmac.an macro
306 package (Linux man page format) instead of the original BSD
307 format. They should be now cleaner and easier to modify.
308
309 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
310 ==================================================================
311
312 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
313 non Linux clients were misinterpreted. The description of the problem
314 (incompatible numbering in Linux mtio opcodes) is documented at
315 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
316 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
317 providing an excellent, cross-platform replacement for rmt in his
318 star package.
319
320 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
321 which caused restore to fail when the inode maps were not entirely
322 contained on the first volume (when using really small volumes or
323 when dumping a huge number of inodes).
324
325 3. Fixed a problem in dump, where files in subdirectories of directories
326 that have the nodump flag set (or being excluded with -e/-E) were
327 sometimes incorrectly dumped (instead of being excluded). The original
328 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
329 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
330 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
331 help testing the patch.
332
333 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
334 which makes one able to pipe the output of dump, by the net, to
335 a remote CD-burner server.
336
337 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
338 and use GNU's symbolic syntax over rmt instead of numerical values
339 to assure multiple platform compatibility.
340
341 6. Documented the -d option in restore.
342
343 7. Added a -v (verbose) mode to dump. For now it just prints the number
344 of the inode being dumped, but this could evolve in future versions
345 to include interesting debugging output.
346
347 8. Added a -o flag to restore, which automatically restores the current
348 directory permissions in -i or -x mode, without asking the operator
349 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
350 and Peter Samuel <peters@e-smith.com>.
351
352 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
353 ====================================================================
354
355 1. Fixed a bug in the QFA feature which could have caused
356 a bad tape positionning on restore (causing extra delays in
357 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
358
359 2. Added a small note in the dump man page specifying that
360 there should be no white space between the option letter and
361 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
362
363 3. Made restore work with older versions of the readline library,
364 by checking in configure for several extended symbols. Restore
365 can now be compiled with a readline as old as the 2.0 release
366 (though it may be a good idea to upgrade it to a more recent
367 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
368 reporting the build failures.
369
370 4. Fixed a performance problem with the QFA file creation in
371 dump, which made unnecessary seeks on the tape slowing down
372 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
373 reporting this issue.
374
375 5. Removed the inclusion of some kernel headers in the dump
376 source, which prevented the compile in some kernel/glibc
377 headers/architecture combination. Thanks to Bdale Garbee
378 <bdale@gag.com> for reporting the bug.
379
380 6. Added the appropriate error message when dump fails to
381 open the output file for writing. Thanks to Amith Varghese
382 <amithv@yahoo.com> for reporting this bug.
383
384 7. Made restore able to understand large Solaris ufsdump tapes
385 (containing inodes bigger than 4194304). Sun have introduced
386 an "extension" to the dump tape format when dealing with
387 those inodes, which was uncorrectly handled by Linux restore.
388 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
389 providing a test case.
390
391 8. Added the -m parameter to dump which optimises the output for
392 inodes having been changed but not modified since the last dump
393 ('changed' and 'modified' have the meaning defined in stat(2)).
394 For those inodes, dump will save only the metadata, instead of
395 saving the entire inode contents. Inodes which are either
396 directories or have been modified since the last dump are saved
397 in a regular way. Uses of this flag must be consistent, meaning
398 that either every dump in an incremental dump set have the flag,
399 or no one has it.
400
401 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
402 =======================================================================
403
404 1. Fixed behaviour of dump when exceeding resource limits
405 (SIGXFSZ treatment).
406
407 2. Added the -L flag to restore to allow the user to specify a
408 maximal allowed number of miscompares when using restore
409 with the -C option to check the backup.
410
411 3. Detailed the manual entry for the -N option of restore.
412
413 4. Added the -a flag to restore to make able doing unattended
414 restores in -i or -x mode (automatically walks through the
415 multiple dump volumes).
416
417 5. Extended the QFA mode to work with local files and/or
418 remote tapes and files. This way, restore can know in advance
419 the tape number and the offset for the inodes to extract and
420 can minimize the extraction time by seeking directly to the
421 good tape/offset.
422
423 6. Added the -A <archive> option to both dump and restore,
424 which makes dump to archive a dump table-of-contents in
425 the specified file to be used by restore to determine
426 whether a file is in the dump file that is being restored.
427 (the archive file syntax is also compatible with the
428 Solaris ufsdump generated one).
429
430 7. Small fix in restore making it able to read some (broken ?)
431 Solaris ufsdump tapes.
432
433 8. Fixed dump to correctly recognise the root filesystem when using
434 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
435 for reporting this bug.
436
437 9. Added the -P <file> option to restore to create a
438 Quick File Access file from an already made dump. Patch
439 contributed by Uwe Gohlke <uwe@ugsoft.de>.
440
441 10. Made restore compile and run on Solaris, making it a
442 possible replacement for the standard ufsrestore. Port was
443 contributed by Uwe Gohlke <uwe@ugsoft.de>.
444
445 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
446 =====================================================================
447
448 1. Added a set of backup scripts from Eugenio Diaz
449 <getnito@yahoo.com> in the examples section. It features
450 automatic (cron based) full and incremental dumping of
451 several filesystems on a separate filesystem.
452
453 2. Fixed a off-by-one miscalculation which disabled dumping
454 a one letter subdirectory. Thanks to Chris Siebenmann
455 <cks@utcc.utoronto.ca> for reporting the bug.
456
457 3. Fixed several restore bugs occuring when trying to
458 restore some missing files on the tape. Thanks to Chris
459 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
460
461 4. Fixed --with-ldopts configure argument passing, installing from
462 a separate object directory, makefile cleanups contributed
463 by <splite@purdue.edu>.
464
465 5. Fix a bug which could caused, in some conditions, the highest
466 number inode of a filesystem, to not be dumped. Many thanks
467 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
468 chase this bug.
469
470 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
471 =======================================================================
472
473 1. Added a mini howto from Patrick Walsh in the examples
474 directory.
475
476 2. Minor man pages syntax corrections. Thanks to
477 Chris Danis <screechco@home.com> for reporting the bugs.
478
479 3. Added a script from David B. Peterson <dave@toppledwagon.com>
480 to the examples section. It features dumping several
481 filesystems to a remote tape drive upon ssh.
482
483 4. Added a patch provided by Richard Jones <rich@annexia.org>
484 which allows BRADEMAX (number of read errors tolerated by
485 dump) to be adjusted using the -I option.
486
487 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
488 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
489 patch.
490
491 6. Add the -l option to restore to specify if, when doing a
492 remote restore, the file used to access the backup is a
493 regular file (the defaults being a tape drive). Restore needs
494 to know this information when reading a remote compressed
495 dump. Previously, this information was autodetected, but
496 the autodetection code fails (with ioctl: Inappropriate ioctl
497 for device) when using a non Linux remote box. Thanks to
498 many users and especially to Eros Albertazzi
499 <eros@lamel.bo.cnr.it> for reporting this.
500
501 7. Found a workaroung for the dump deadlock problem (3 childs
502 stuck in pause(), father in read()). The workaround seems
503 to work for me and several beta-testers. If it doesn't work
504 for you, please report back.
505
506 8. Updated the RPM spec file (BuildPrereq, URL etc).
507
508 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
509 ========================================================================
510
511 1. Fixed the permissions of a newly created QFA file by dump.
512
513 2. Cleaned up the source of dump (the external variables
514 definition was a complete mess, making possible to have
515 objects overlap).
516
517 3. Fixed restore to use the full tape volume path when doing
518 a compare (since it changes the working directory to the
519 filesystem being compared in the process).
520
521 4. Added the -q option to dump which makes dump abort
522 whenever it needs operator attention. It should be
523 easier to use dump in scripts with this option.
524
525 5. Detect the use of incompatible options to dump and
526 refuse them (like -a and -B options together).
527
528 6. Added bzip2 compression to dump/restore (use option -j level
529 to select it). Note that you will need a restore version
530 >= 0.4b24 in order to restore a bzip2 compressed dump.
531 The same warning as for the zlib compression applies:
532 the tape format of a bzip2 dump is not compatible with the
533 original BSD tape format.
534
535 7. Fixed a overflow problem in dump corrupting the dump when
536 very large files were encountered. Thanks to Vladimir Nadvornik
537 for the bug report.
538
539 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
540 kernel buffer/page cache before starting the dump, helping
541 a bit those who use dump on mounted filesystems. Thanks to
542 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
543 for this suggestion.
544
545 9. Updated the RPM spec file following the RedHat changes
546 (dynamically linked binaries now in /usr/sbin etc).
547
548 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
549 which enables restore to recognise multi volume compressed dumps
550 done on CD. Included his scripts for dump (which pipe the dump
551 output directly into cdrecord) and restore. There is now
552 possible to to backups to CD on the fly!
553
554 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
555 ===================================================================
556
557 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
558 Marcus Meissner (Caldera International Security Dept.).
559
560 2. Implement the Sun rmt extended protocol. Patch submitted
561 by Ian Gordon <iangordon@users.sourceforge.net>.
562
563 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
564 the linux kernel header. This ensures that dump always has the
565 latest version of this file. Patch submitted by
566 Andreas Dilger <adilger@turbolinux.com>.
567
568 4. Report any filesystem present in either /etc/fstab with a
569 positive passno or /etc/dumpdates in dump -w output.
570 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
571
572 5. Fixed the looping problem in dump introduced in the
573 previous version.
574
575 6. Changed the -B option of dump to limit the size of
576 _compressed_ output per volume if compression is on.
577 Patch contributed by Helmut Jarausch
578 <jarausch@igpm.rwth-aachen.de>. Note however that, since
579 it is impossible to predict the size of the compressed
580 data before doing the compression, the -B limit is a bit
581 conservative.
582
583 7. Fixed a bug in reading the operator typed file/tape path for
584 the next volume in restore.
585
586 8. Implemented a "-F script" option to restore which permits the
587 user to specify a script which will be launched at the
588 beginning of each tape, useful for automatic programming of
589 tape changers for example. See the restore man page for the
590 script parameters and return codes.
591
592 9. Small fix for the QFA routines provided by Uwe Gohlke
593 <uwe@ugsoft.de>, and some recommendations for QFA uses in
594 the man pages.
595
596 10. Fixed the multivolume restoring where making a mistake
597 to the 'Mount next tape' prompt caused several blocks to
598 be lost.
599
600 11. Enhanced the -e option of dump to take as a parameter a
601 comma separated list of inode numbers.
602
603 12. Added the -E option to dump which specify a file containing
604 inode numbers to exclude from the dump.
605
606 13. Fixed the compressed multi-volume dump + restore.
607
608 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
609 ==================================================================
610
611 1. Made dump report the number of blocks dumped per volume.
612 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
613
614 2. Fix a bug in dump where waiting too much at the 'change volumes'
615 question caused the volume to be rewritten. Thanks to
616 Graham Reed <greed@users.sourceforge.net> for reporting the
617 bug and providing a patch.
618
619 3. Added a compression option to dump, contributed by Jerry
620 Peters <gapeters@worldnet.att.net>.
621
622 WARNING: the compression works only on files/pipes and
623 drives supporting variable block size.
624
625 WARNING2: tapes created using the compression feature are
626 incompatible with the standard dump tape format, and a
627 version of restore >= 0.4b22 will be needed for extraction.
628
629 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
630 architectures. Thanks to Paul Slootman <paul@debian.org> for
631 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
632 it upstream.
633
634 5. Many cleanups (CPP defines, const char warnings, check of
635 ext2fs COMPAT flags, time_t cleanups, added libext2 version
636 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
637
638 6. Made --prefix option work in configure. All the install path
639 are now based on the configure parameters.
640
641 7. Added the Quick File Access mode in dump/restore, contributed
642 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
643 a file tape position for each inode, and this file is used by
644 restore (if called with parameter Q and the filename)
645 to directly position the tape at the file restore is currently
646 working on. This saves hours when restoring single files from
647 large backups, saves the tapes and the drive's head. Use
648 --enable-qfa option of configure to compile in the QFA support.
649
650 8. Added the possibility to dump several files and directories
651 in a single invocation of dump. Thanks to Uwe Gohlke
652 <uwe@ugsoft.de> for implementing this option.
653
654 9. Fixed the dumping and restoring of files with holes
655 (files ending with holes didn't get dumped or restored
656 correctly).
657
658 10. Fixed a socket descriptor leak in dump, which leaved opened
659 3 file descriptors per dump process (and there is one dump
660 process per tape).
661
662 11. Fixed dump large file system support, by explicit use of
663 open64/lseek64/etc functions (explicit use needed because
664 e2fsprogs libraries don't behave well when compiled with
665 FILE_OFFSET_BITS=64).
666
667 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
668 ======================================================================
669
670 1. Fixed some bugs in the dump -w|-W logic introduced by
671 the previous version. Thanks to Andreas Dilger
672 <adilger@turbolinux.com> for his help on this one.
673
674 2. Fixed again a compilation problem when using old e2fs
675 headers (filesystem label related). Thanks to many users
676 who reported this stupid error.
677
678 3. Fixed a build problem on old lib5 based systems dealing with
679 _PATH_MNTTAB being undefined. Thanks to John Adams
680 <johna@onevista.com> for reporting the bug.
681
682 4. Improved the error detection in restore when creating
683 the temporary files in TMPDIR. Now restore will corectly
684 report a 'no space left on device' error instead of
685 strange errors which could imply an archive corruption.
686 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
687 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
688
689 5. Added the throughput information in dump's progression
690 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
691 for the patch.
692
693 6. Use libext2fs's inode scanning routines, which are particularly
694 robust when dealing with errors (especially when having some
695 bad blocks on the filesystem). Many thanks to Colin
696 <colin@horizon.com> for reporting the bug, investigating
697 the issues, finding a workaround, writing the patch and
698 fully testing it... (of course, if this patch will break
699 anything, he is to blame for :-)).
700
701 7. Made dump and restore LFS aware. Dump can dump a filesystem
702 containing large files, generate a large file on output and
703 restore can restore them. This feature is not enabled by
704 default, use --enable-largefile option of configure to enable
705 it (you need to have a LFS aware glibc though). Thanks to
706 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
707 and to Theodore T'so <tytso@valinux.com> for his always
708 useful thoughts.
709
710 8. Made dump ask upon a tape write error if it should rewrite
711 the current volume (assume this is a bad tape) or if it should
712 assume an end-of-tape condition (useful for tape drives which
713 behaves badly at the end of the tape). Thanks to Andreas
714 Dilger <adilger@turbolinux.com> for the suggestion.
715
716 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
717 =======================================================================
718
719 1. Fixed a small compilation problem due to a change
720 in the definintion of the struct sigaction in
721 glibc 2.0 / libc5. Thanks to Gunther Schlegel
722 <schlegel@riege.de> for reporting the bug and to
723 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
724 a fix.
725
726 2. Modified the label and uuid analysis in order to be
727 self-contained (independant of kernel/libc headers). This
728 should fix the compile with older kernel/libc headers and
729 will preserve the functionality. Thanks to Bernhard Erdmann
730 <bernhard.erdmann@gmx.de> for reporting the bug.
731
732 3. The 'exclude inode' option, if applied to a directory
733 inode, excludes now correctly all the leaves of this
734 directory. Thanks to John R. Dennison
735 <gerdesas@users.sourceforge.net> for reporting the bug.
736
737 4. Fixed the '-e' option to disable the possibility
738 to exclude the root inode (which causes the dumps to
739 be unreadable by restore). Prevented array overflow
740 when multiple -e options are used.
741
742 5. Fixed dump to correctly interpret a filesystem argument
743 which is a mountpoint and it is not an absolute path
744 (as specified in the fstab). Thanks to Bernhard R. Erdmann
745 <be@berdmann.de> for reporting the bug.
746
747 6. Made dump able to backup files larger than 2 GB. Note that
748 dump still doesn't cope with files larger than 4 GB.
749
750 7. Restore the real uid and gid before invoking an external
751 RSH program (big hole when dump or restore is suid root!).
752
753 8. Get the values for the default tape device and the location
754 of fstab file from the system headers. Thanks to
755 Andreas Dilger <adilger@turbolinux.com> for the patch.
756
757 9. Made dump -w|-W report all recognized filesystems
758 present in either /etc/fstab or /etc/dumpdates, and present
759 the list in the same order as in fstab file. Thanks
760 to Andreas Dilger <adilger@turbolinux.com> for the patch.
761
762 10. Made dump's -a (automatic end of tape detection) the
763 default. Specifying one of -B, -c, -d or -s options will
764 override the EOM detection. Thanks to Andreas Dilger
765 <adilger@turbolinux.com> for the patch.
766
767 11. Save the ext2 filesystem label into the dump volume label.
768 Specifying a volume label on the command line (-L option)
769 will override this feature. Thanks to Andreas Dilger
770 <adilger@turbolinux.com> for the patch.
771
772 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
773 =====================================================================
774
775 1. Fixed the signal handling in dump (which I broke in 0.4b17)
776 which was causing several strange dump failures (dump
777 hanged or segmentation faults etc).
778
779 2. Specified the default blocksize in the dump man page.
780
781 3. Changed two info messages of restore to be written on stdout
782 instead of stderr in order to leave stderr only for errors
783 or warnings. Thanks to Stephen Atwell
784 <satwell@urbana.css.mot.com> for the suggestion.
785
786 4. Corrected an off by one calculation which prevented
787 dumping a directory having a 1 character name length.
788 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
789 for reporting the bug.
790
791 5. Reinforce dump in order to allow only level 0 and no
792 -u option when dumping a subdirectory, and document
793 this in the man page. Thanks to Bernhard Erdmann
794 <bernhard.erdmann@gmx.de> for reporting the bug.
795
796 6. Fixed a small harmless bug in restore which caused
797 in some conditions hard links to be restored several
798 times (therefore generation some warning messages).
799 Thanks to Kenneth Porter <shiva@well.com> for
800 reporting the bug.
801
802 7. Updated the RPM spec file to the latest RedHat version,
803 providing FHS packaging and other cosmetic changes.
804 You will need RPM version >= 3.0.5 in order to build the RPM.
805
806 8. Updated the configure script to check for libtermcap
807 before checking for libreadline, because we need this
808 library in order to compile the readline support.
809
810 9. Made dump understand the LABEL= and UUID= notation
811 both in /etc/fstab and on the command line. Note that
812 you will need the /proc filesystem in order to use
813 these notations. Thanks to Erik Troan <ewt@redhat.com>
814 for providing the patch.
815
816 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
817 ===================================================================
818
819 1. Fixed a potential buffer overflow in restore. Thanks
820 to Stan Bubrouski <satan@fastdial.net> for reporting
821 the bug.
822
823 2. Fixed a readline-related bug which prevented
824 'cat DUMPFILE | restore -i -f -' from working. Thanks
825 to Charles Karney <karney@users.sourceforge.net>
826 for the bug report.
827
828 3. Changed a few "panic" into "exit", causing restore to
829 be more stable against some attacks (like the last one
830 reported on Bugtraq, although the last version of restore
831 was not vulnerable - just dumped core). Thanks to
832 Andreas Hasenack <andreas@conectiva.com.br> for reporting
833 the bugs to me.
834
835 4. Removed the suid-root bit on dump and restore in the
836 default build (and generated RPMs). It should be safer
837 now. Users who need the suid-root capabilities in order
838 to make network backups should read first the man page
839 of dump and enable the suid bit manually.
840
841 5. Added -ltermcap to the compile parameters for restore
842 when using readline support, in order to make the compile
843 process work on some systems (SuSE ?). Thanks to
844 Patrik Schindler <poc@pocnet.net> for reporting the bug.
845
846 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
847 ====================================================================
848
849 1. The -F script is called now *only* at the end of a tape,
850 not at the end of the dump. Thanks to Christian Haul
851 <haul@informatik.tu-darmstadt.de> for the bug report.
852
853 Normally, the device name and the current volume number
854 are passed on the command line of the script. However,
855 if you want the old style script (with no arguments
856 passed on the command line), you can enable it in
857 configure with the --enable-oldstylefscript.
858
859 2. Use posix signal handling to preserve dump functionality
860 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
861 the patch.
862
863 3. Made the exit code of restore in case of a 'C'ompare
864 command reflect the result of the compare. An exit status
865 of 0 means the dump archive is correct, 1 means tape errors,
866 2 means that some files were modified. Thanks to Kenneth Porter
867 <shiva@well.com> for the suggestion.
868
869 4. Made (finally) quotes work in interactive restore.
870
871 5. Small fixes in order to allow dump to compile with a
872 really old e2fsprogs version. Thanks to Ian Zimmerman
873 <itz@speakeasy.org> for the bug report.
874
875 6. Add GNU readline capabilities to interactive restore.
876 Use configure's --enable-readline flag to enable this feature.
877 Thanks to Patrik Schindler <poc@pocnet.net> for the
878 suggestion.
879
880 7. Do the compare on the fly in restore 'C' mode (this will
881 allow not to exhaust the available /tmp space when
882 ccmparing large files). Thanks to Kenneth Porter
883 <shiva@well.com> for the suggestion.
884
885 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
886 ====================================================================
887
888 1. Fixed some several duplicate 'DUMP: DUMP:' in the
889 output of dump.
890
891 2. Corrected the estimation of blocks to dump. Note that
892 this is still wrong for large directory inodes, due
893 to the size of a BSD directory entry on the tape
894 (estimation is based on the size of the ext2 directory,
895 which is smaller because it doesn't contain the null
896 character at the end).
897
898 3. Made dump report the total number of MB written to
899 tape at the end of run. Thanks to W. Reilly Cooley
900 <wcooley@nakedape.cc> for the patch.
901
902 4. Added the -X option to restore giving the possibility
903 to read the names of the files to be extracted/listed
904 from a text file (in addition of the command line).
905 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
906 patch.
907
908 5. Added the device name and the current volume number
909 as arguments to the end of tape script (dump -F option).
910
911 6. Made the multi-volume dump work again (after having
912 broken it in 0.4b15).
913
914 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
915 ===================================================================
916
917 1. Added a prompt command in interactive restore mode. Thanks
918 to Andreas Dilger <adilger@home.com> for the patch.
919
920 2. Fixed a buffer overflow problem in dump (caused by
921 not checking the size of the filesystem parameter).
922 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
923 reporting this on Bugtraq (and to several dump users
924 who forwarded me his mail).
925
926 3. Added the '-F script' option to dump in order to
927 launch a script at the end of each tape (to be used
928 with a tape changer, or to notify the sysadmin by
929 pager etc.).
930
931 4. Fixed a bug in restore compare code caused by the changes
932 I made in 0.4b14.
933
934 5. Fixed the treatment of options using the old BSD syntax
935 in both dump and restore.
936
937 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
938 =======================================================================
939
940 1. Fixed a bug in dump which may have caused invalid deleted
941 directories to be dumped out if they were deleted after the
942 mapping pass. This could occure on active filesystem and lead
943 to heap corruption (causing dump malfunction in many possible ways).
944 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
945 bug and submitting the patch.
946
947 2. Fixed the handling of the filesystem parameter in dump. A
948 '/mnt/disk' parameter caused the disk contents to be dumped,
949 but a '/mnt/disk/' parameter caused the mountpoint directory
950 to be dumped (generally an empty directory).
951
952 3. Improved the output of dump in order to tell which directory
953 it is currently dumping (when dumping a subtree).
954
955 4. Added the '-e' exclude inode option to dump. Thanks to
956 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
957
958 5. Added a REPORTING-BUGS file in order to provide a guide
959 on how to correctly report a bug in dump/restore.
960
961 6. Fixed a restore problem when restoring a hard link to an inode
962 having the immutable or append-only attribute set. Thanks to
963 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
964
965 7. Fixed a compatibility problem between dumps made on little
966 endian machines (the format was correct) and big endian
967 machines (the format was incorrect). This fix break the
968 compatibility with the older dumps made on big endian
969 machines (sparc, m86k, ppc etc). For the first time in
970 linux dump's history (I believe), the dumps made by *BSD,
971 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
972 so interchangeable. Thanks to Rob Cermak
973 <cermak@ahab.rutgers.edu> for submitting the bug and
974 helping me test the fix.
975
976 8. Fixed the way dump reports the remaining percent/time, if
977 the number of blocks actually dumped exceeds the estimated
978 number of blocks. Thanks to Jean-Paul van der Jagt
979 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
980
981 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
982 ======================================================================
983
984 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
985 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
986
987 2. Removed the requirement to build the RPM as root from the
988 spec file. Thanks to Christian Weisgerber
989 <naddy@mips.rhein-neckar.de> for submitting this.
990
991 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
992 causing dump to block when dumping really huge filesystems.
993 Many thanks to Patrik Schindler <poc@pocnet.net> for
994 helping me find this bug.
995
996 4. Fixed the treatment for an interrupt signal when dump access
997 the remote tape through RSH. Thanks to Christian Weisgerber
998 <naddy@mips.rhein-neckar.de> for providing the patch.
999
1000 5. Fixed a bug which was causing dump/restore to display
1001 garbage characters instead of the remote host name.
1002
1003 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1004 =====================================================================
1005
1006 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1007 <kukuk@suse.de> for submitting the patch.
1008
1009 2. Fix for the exit code when using the size estimate option of
1010 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1011 submitting the patch.
1012
1013 3. Handle EINTR in atomical reads/writes in dump, which was causing
1014 dump to fail on some systems. Thanks to Eric Jergensen
1015 <eric@dvns.com> for reporting the bug and submitting the patch.
1016
1017 4. Handle more than 16 characters for the device names in dumpdates.
1018 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1019 tracking down the problem and proposing the solution.
1020
1021 5. Fixed a bug in dump which prevented the creation of the
1022 dumpdates file when doing a 0-level dump without already
1023 having a dumpdates file. Thanks to Patrik Schindler
1024 <poc@pocnet.net> for reporting the bug.
1025
1026 6. Changed the way dump 'S' flag reports the size estimate
1027 from number of blocks into bytes (making it compatible
1028 with the Solaris version, and simplifying things for
1029 amanda users). Thanks to Jason L Tibbitts III
1030 <tibbs@math.uh.edu> for reporting the bug.
1031
1032 7. Fixed a compatibility problem in linux/alpha dump tape format.
1033 Now the linux/alpha dump are (again) compatible with the
1034 other dump formats. But this breaks compatibility with
1035 older dumps made on alpha. Thanks to Mike Tibor
1036 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1037
1038 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1039 ======================================================================
1040
1041 1. Added a '--enable-kerberos' to configure.
1042
1043 2. Added a 'S' option to dump which determines the amount of space
1044 that is needed to perform the dump without actually doing it, similar
1045 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1046 <cermak@ahab.rutgers.edu>.
1047
1048 3. Added a 'M' multi-volume option to dump and restore which enables
1049 dumping to multiple files (useful when dumping to an ext2
1050 partition to make several dump files in order to bypass the 2GB
1051 file size limitation). The 'f' argument is treated as a prefix and
1052 the output files will be named <prefix>001, <prefix>002 etc. With
1053 the 'M' flag, restore automatically selects the right file without
1054 asking to enter a new tape each time.
1055
1056 4. Fixed a memory leak which was causing dump to grow very big
1057 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1058 Fearon <jasonf@netrider.org.au> for reporting the bug.
1059
1060 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1061 ======================================================================
1062
1063 1. Make configure test if the system glob routines support
1064 extended syntax (ALTDIRFUNC). If not, use the internal glob
1065 routines instead of system ones. Thanks to Bernhard Sadlowski
1066 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1067 and helping me resolve this and other minor libc5 compiling
1068 glitches.
1069
1070 2. Fix a problem when dumping a ext2fs with the 'filetype'
1071 feature enabled. Thanks to Patrick J. LoPresti
1072 <patl@cag.lcs.mit.edu> for reporting the bug and to
1073 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1074
1075 3. Made the nodump flag work on directories. A directory which
1076 has the nodump flag gets never dumped, regardless of its
1077 contents.
1078
1079 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1080 which allows dump on an active ext3 filesystem. However, this
1081 is a "quick and dirty" patch which enables backup of an ext3
1082 filesystem through the ext2 compatibility (by ignoring the
1083 NEEDS_RECOVERY bit). The journal file is not recognized and
1084 it is dumped (it should not).
1085
1086 5. Test the superblock compatibility flags when dumping, in order
1087 to be sure that we know how to deal with specific features.
1088
1089 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1090 ====================================================================
1091
1092 1. Use lchown instead of chown, fixing a possible security problem
1093 when restoring symlinks (a malicious user could use this
1094 to deliberately corrupt the ownership of important system files).
1095 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1096 this and providing the patch.
1097
1098 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1099 ====================================================================
1100
1101 1. Put dump sources under CVS, added Id tags in all files so
1102 one can use 'ident' on binary files.
1103
1104 2. Added the dump/restore version in the usage text so one can
1105 easily verify the version he is using.
1106
1107 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1108 a va_start/va_end problem on linux-ppc (always call va_start
1109 va_end in pairs each time we use a vararg function).
1110
1111 4. Added again the DT_* constants because old libc does not
1112 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1113 for submitting the bug report.
1114
1115 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1116 this should enable dumping big (huge) filesystems.
1117
1118 6. Added the RSH environment variable in order to be able to
1119 use a rsh replacement like ssh when doing remote backups (and
1120 bypass the security limitations of rcmd). Now you can do remote
1121 backups without being root (or making dump setuid root).
1122
1123 7. Modified again the way dumpdates works. For incremental dumps,
1124 we need to read dumpdates even if we are not using 'u' option.
1125 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1126 this should work.
1127
1128 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1129 ===================================================================
1130
1131 1. Removed the 'k' flag from the restore 'about' text if kerberos
1132 was not compiled in.
1133
1134 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1135 to them (fsetflags takes a char*, setflags an open fd!).
1136
1137 3. (f)setflags is called only if the flags aren't empty. If the
1138 file is a special file, a warning is printed, because changing
1139 flags implies opening the device. Normally, a special file
1140 should not have any flag... (Debian bug #29775, patch provided
1141 by Abhijit Dasgupta <abhijit@ans.net>).
1142
1143 4. Made possible to dump a file system not mentioned in /etc/fstab.
1144 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1145
1146 5. Changed the default behaviour to not create dumpdates
1147 unless 'u' option is specified. Removed the old "debian-patch"
1148 which provided the same thing. (Debian bug #38136, #33818).
1149
1150 6. Removed all those dump*announce, since they were getting old...
1151
1152 7. Added warning messages if dumpdates does not exist and
1153 when an inferior level dump does not exist (except for a level 0
1154 dump).
1155
1156 8. Debugged the glob calls in interactive mode: restore used a
1157 dirent struct which was different from the /usr/include/dirent.h
1158 one (this used to work, is it a glibc2 change?), so none of the
1159 compat glob (which used /usr/include/dirent.h) or the system glob
1160 worked. Restore use now the system dirent (and the system
1161 DT_* constants), which are compatible with BSD ones.
1162
1163 9. Added a configure flag (--with-dumpdatespath) to specify
1164 the location of dumpdates file. By default, it is
1165 /etc/dumpdates.
1166
1167 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1168 included the current date/version in man pages.
1169
1170 11. Corrected the estimation of remaining time when
1171 the operator doesn't change the tapes quickly enough. This
1172 was an old bug, I thought I corrected it, and discovered
1173 that in fact it was corrected in two different places, so
1174 the results canceled each other...
1175
1176 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1177 ===================================================================
1178
1179 1. Integrated multiple patches from RedHat, Debian and SuSE:
1180
1181 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1182 isn't specified.
1183 - several fixes in the man pages.
1184 - update the default tape device to /dev/st0.
1185 - many updates for Linux Alpha (byte ordering, size_t etc).
1186 - buffer overruns.
1187 - use environment variable for TMPDIR (instead of /tmp).
1188 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1189 - workaround egcs bug (RedHat bugs #4281 and #2989).
1190 - wire $(OPT) throughout Makefile's.
1191
1192 2. Upgrade the dump revision to 1, making possible to dump filesystems
1193 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1194
1195 3. Fix some compile warnings, prototype all functions.
1196
1197 4. Use glibc err/glob instead of internal compatibility
1198 routines (only if available).
1199
1200 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1201 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1202
1203 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1204 ======================================================================
1205
1206 1. Integrated the changes from FreeBSD-3.1-RELEASE
1207 (mostly bug fixes, buffer overruns, dump has now an "automatic
1208 tape length calculation" flag, dump/restore can use kerberos now
1209 (this is NOT tested), use environment variables for TAPE and
1210 RMT etc.).
1211
1212 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1213
1214 3. Corrected a bug in restore when using 'C' option with multi-volumes
1215 tapes (files splited accros two tapes give "size changed" errors
1216 when comparing).
1217
1218 4. Corrected the long standing bug when dumping multiple tapes.
1219 This works for me, needs further testing.
1220
1221 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1222 ====================================================================
1223
1224 1. Dump now runs correctly on kernels 2.1.x
1225 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1226
1227 Changes between versions 0.4b2 and 0.4b3
1228 ========================================
1229
1230 1. Use realpath() if available
1231
1232 2. Report statistics
1233
1234 Changes between versions 0.4b1 and 0.4b2
1235 ========================================
1236
1237 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1238 the patch)
1239
1240 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1241
1242 3. Fixed configure.in to correctly handle --enable-rmt
1243
1244 Changes between versions 0.3 and 0.4b1
1245 ======================================
1246
1247 1. Integrated the changes from 4.4BSD-Lite2
1248
1249 2. Integrated the patches from Debian and Red Hat
1250
1251 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1252
1253 4. Changed dump to use the Ext2fs library to get block addresses. This
1254 should solve the endianness problem on SparcLinux.
1255
1256 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1257 distribution's one) to use autoconf
1258
1259 6. Fixed a few minor bugs
1260
1261 Changes between versions 0.2e and 0.2f
1262 ======================================
1263
1264 1. Added the creation of named pipes (fifos) in restore.
1265
1266 2. Added the -N flag in the restore manual page.
1267
1268 3. Added the file kernel.patch which contains the llseek() optimization
1269 patch for 1.2.x kernels.
1270
1271 4. Fixed a bug in the restoration of symbolic links: owner and group were
1272 not restored.
1273
1274 5. Integrated some changes from FreeBSD 2.2.
1275
1276 6. Added a call to ftruncate() after restoring each file to restore
1277 correctly files ending by a hole.
1278
1279 Changes between versions 0.2d and 0.2e
1280 ======================================
1281
1282 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1283 with owner = root (0) and group = root/wheel/whatever (0).
1284
1285 Changes between versions 0.2c and 0.2d
1286 ======================================
1287
1288 1. Dump is now able to backup 2GB+ filesystems.
1289
1290 2. Dump and restore can now be linked as static binaries.
1291
1292 Changes between versions 0.2b and 0.2c
1293 ======================================
1294
1295 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1296
1297 Changes between versions 0.2a and 0.2b
1298 ======================================
1299
1300 1. Really fixed the bug that I should have corrected in 0.2a.
1301
1302 2. Enabled optimization again.
1303
1304 Changes between versions 0.2 and 0.2a
1305 =====================================
1306
1307 1. Disabled the optimization during compilation.
1308
1309 Changes between versions 0.1 and 0.2
1310 ====================================
1311
1312 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1313 the fs_type field (actually, I modified the file fstab.c to make it
1314 use the mntent functions).
1315
1316 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1317 made by dump should be readable by the BSD restore and backups made
1318 by the BSD dump should be readable by restore. Unfortunately, this
1319 means that the dump format has changed between version 0.1 and version
1320 0.2 :-(
1321
1322 3. Dump is now able to backup a subtree, it is no longer limited to whole
1323 filesystems like the BSD version.
1324
1325 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1326 than 2 GB.
1327
1328 Changes between versions 0.0 and 0.1
1329 ====================================
1330
1331 1. Now create links rdump and rrestore during the `make install' step.
1332
1333 2. Linux port specific bugs added to the manual pages
1334
1335 3. Incorrect estimation of the number of tapes blocks fixed when doing
1336 incremental backups.
1337
1338 4. Better ls-like format in restore in interactive mode.
