2
3 Changes between versions 0.4b39 and 0.4b40 (released ????????????????)
4 ======================================================================
5
6 1. Changed restore to emit warnings (instead of emitting a fatal
7 error) if a file (or a directory) is unavailable for a
8 comparision (if the user doesn't have the necessary permissions
9 to access it for example). Thanks to Kenneth Porter
10 <shiva@sewingwitch.com> for the bug report.
11
12 2. Re-done the 'do not save directory entries to non-dumped inodes
13 (excluded from dump)' feature. The previous implementation
14 worked well for excluded directories but not for regular files.
15 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
16 report.
17
18 Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
19 ======================================================================
20
21 1. The newly added dump_on_cd_3 example was buggy, replace it
22 with an updated version from Andrew Basterfield
23 <bob@cemetery.homeunix.org>.
24
25 2. Made restore to chdir() back into the initial directory when
26 dumping core while aborting a comparision operation. The
27 previous behaviour was to write the corefile at the root of
28 the directory being compared, which could very well be
29 read only and preventing the corefile generation. Thanks
30 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
31
32 3. Silenced the failure to call fgetflags() when comparing an
33 entry which has no ext2 attributes (as in lsattr()).
34
35 4. Fix a brown paper bug in restore -C which broke restore and
36 caused modifications on the filesystem being compared
37 (directories containing a file with the same name as the
38 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
39 <shiva@sewingwitch.com> for finding the bug and helping me
40 reproduce it.
41
42 5. Made restore -C force the -N flag (no writing allowed on
43 the disk) in order to prevent more bugs like the above one.
44
45 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
46 =====================================================================
47
48 1. Fix a couple of troff syntax bugs in the man pages.
49 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
50
51 2. Made restore use either libncurses or libtermcap, depending
52 on which one is available at configure time.
53
54 3. Fixed restore negative size display bug when comparing a
55 dump containing files over 2GB. Thanks to Steve Bonds
56 <sbonds@users.sourceforge.net> for the bug report.
57
58 4. Do not save directory entries to non-dumped inodes
59 (excluded from dump). This will eliminate the 'missing
60 file' warnings when doing 'restore -C'.
61
62 5. Fix dump crash when backuping a huge (2TB) filesystem,
63 due to a bogus calculation on the inode map size.
64 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
65 submitting the bug and testing the fix.
66
67 6. Fix a problem in restore where the final \0 in the symbolic
68 link names could have been lost, generating corrupt filenames.
69 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
70 bug.
71
72 7. Implemented a hash list for the directory names in restore.
73 The linear list used before caused problems in interactive
74 restores when dealing with directories having thousands of
75 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
76 for reporting the bug.
77
78 8. Improved restore -C, this time including the directory
79 attributes into the comparision.
80
81 9. Made restore understand tapes containing EA/ACLs (which will
82 be dumped by the next version of dump). In this version
83 extended attributes on the tape are ignored, for full EA/ACL
84 support wait for the next version or try the experimental EA
85 patch.
86
87 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
88 ==================================================================
89
90 1. Added the --enable-staticz configure option which enables
91 dump and restore to be linked with static versions of
92 libz and libbz2 (and dynamic versions of all other libraries).
93 This will make Debian users happy, because libz and libbz2
94 were the only needed libraries living in /usr, all the
95 others live in /lib. In case of system emergency, it is
96 better not to have to rely on an extra filesystem.
97 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
98
99 2. Fix compilation on (at least the Linux Debian port to) AMD64.
100 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
101 that are also defined by <linux/types.h> (<asm/types.h>) and
102 they conflict).
103
104 3. Make dump's reading of the dumpdates file a bit more robust,
105 preventing dump from crashing when the dumpdates file has
106 been modified by hand.
107
108 4. Fixed some offset calculations in dump code which could
109 lead to "bread lseek errors" on large filesystems. Thanks
110 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
111 reporting this bug and debugging the issue.
112
113 5. Made dump use the blkid library when searching for devices
114 by label or uuid instead of dump's own routines.
115
116 6. Corrected a bug in dump where a wrong LABEL=... line in
117 /etc/fstab could prevent dump from dumping unrelated
118 filesystems. Thanks to Bruce Lowekamp
119 <lowekamp@users.sourceforge.net> for reporting the bug.
120
121 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
122 ====================================================================
123
124 1. Fixed dump compilation with old gcc versions. Thanks to
125 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
126
127 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
128 when compiling against a recent glibc version.
129
130 3. Fixed a bug in restore preventing the read of a dump tape
131 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
132 <phiggins@transzap.com> for reporting the bug and providing
133 the test case.
134
135 4. Changed dump to enable the creation of volumes of different
136 sizes in a single run (make -B accept a list of values).
137 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
138
139 5. Use the glibc provided minor() and major() macros instead
140 of our own bitmask implementation. This should be safe for
141 when the major/minor namespace will migrate to 32 bits.
142 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
143 the bug.
144
145 6. Made explicit in the dump man page that dump will not create
146 a remote file, it will only write to an already existing one.
147
148 7. Another try at making size estimates better again.
149
150 8. Put back the inconditional running of the end-of-tape
151 script which was changed in 0.434 to be run only when -M
152 or multiple -f were NOT specified. Some users rely on this
153 feature even when it is combined with -M/-f.
154
155 9. Fixed restore when restoring huge backups (where rstdir...
156 temporary files are over 2GB). Thanks to
157 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
158 debugging the issue and making the patch.
159
160 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
161 David <vrtin@users.sourceforge.net> for submitting the bug
162 and providing a test case.
163
164 11. Made dump work with an arbitrary integer level (no more 10
165 levels only limitation). Thanks to Matthew
166 <msvincen@midway.uchicago.edu> for the patch.
167
168 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
169 =======================================================================
170
171 1. Added a note in the dump man page saying that the default
172 blocksize can be 32 if -d is used with a high density argument.
173 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
174 for the patch.
175
176 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
177 LDFLAGS environment variables. Thanks to Arcady Genkin
178 <antipode@users.sourceforge.net> for reporting the bug.
179
180 3. Made -e/-E options of dump accept an unlimited number of inodes
181 to be excluded, rather than a hardcoded maximum. Thanks to
182 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
183
184 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
185 and -D_USE_BSD_SIGNAL defines in configure in order to solve
186 64bit build problems because quad_t is redifined with a
187 different signature. Thanks to Mike Harris <mharris@redhat.com>
188 for reporting this bug.
189
190 5. Made restore build on Solaris, making possible to
191 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
192 <uwe@ugsoft.de> for the patch.
193
194 6. Made an extension in the dump tape format capable of saving
195 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
196 wrote the extension and contributed the restore code back
197 into this codebase. The same extension mechanism will be
198 used in the future to save ACLs...
199
200 7. Made rmt work correctly with regard to QFA and local/remote
201 files and tapes. The remote access will however work only
202 when the dump provided rmt version is used. If you want to
203 use another rmt server, please do not use the QFA feature.
204 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
205
206 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
207 ====================================================================
208
209 1. Fixed the INSTALL file to reflect the actual install paths.
210 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
211 reporting the bug.
212
213 2. Fixed the configure script to only check for headers presence
214 instead of trying to compile them. This should fix issues
215 with old build environments. Thanks to Kari Lempiainen
216 <kari@funky.pp.fi> for reporting the bug.
217
218 3. Fixed restore to correctly ignore sockets when comparing
219 a dump (as socket cannot be properly restored anyway). Thanks
220 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
221
222 4. Fixed restore to correctly access the archive file (-A argument)
223 even when using a remote tape. Thanks to Fabrice Bellet
224 <fabrice@bellet.info> for reporting the bug.
225
226 5. Fixed (again) handling of long (largefile) seeks in rmt.
227 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
228 the bug.
229
230 6. Fixed restore corner case when dealing with large block sizes
231 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
232 <fabrice@bellet.info> for reporting the bug.
233
234 7. Fixed a bug preventing dump to access a filesystem having
235 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
236 for reporting the bug.
237
238 8. Made dump store dump dates using explicit timezones, fixing a
239 problem with incremental dumps if the timezone is modified
240 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
241 the bug report and the patch.
242
243 9. Fixed a bug encountered when dumping individual files (not full
244 filesystems or directories) and dangling symbolic links happen
245 to be in the list of files. For as far as dump is concerned,
246 dangling symbolic links are allowed, and are dumped as is.
247 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
248 bug and providing the fix.
249
250 10. Fixed open and creation modes and permissions for QFA and
251 table-of-contents files in dump and restore. Thanks to
252 Philippe Troin <phil@fifi.org> for the patch.
253
254 11. Fixed the archive file descriptor handling enabling it to be 0.
255 This can happen in some cases when shell redirections are used.
256 Thanks to Philippe Troin <phil@fifi.org> for the patch.
257
258 12. Delayed the opening of archive file until after suid had been
259 dropped (fixing a possible security issue if dump is suid).
260 Thanks to Philippe Troin <phil@fifi.org> for the patch.
261
262 13. Fixed the 'S' command handling in the rmt client part.
263 Thanks to Philippe Troin <phil@fifi.org> for the patch.
264
265 14. Modified the end-of-tape script handling to print out statistics
266 (and stop the timer) before launching the eot script. Also, the eot
267 script does not get run anymore when using -M (which makes sense) or
268 when multiple tapes are listed on the command line
269 (-f tape0,tape1,tapen) (which also makes sense).
270 Thanks to Philippe Troin <phil@fifi.org> for the patch.
271
272 15. Relicensed dump/restore under the 'revised' BSD license, as per
273 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
274
275 16. Added LZO compression to dump. This new compression method has
276 the advantage of being super fast, thus not killing tape streaming
277 on slow machines. Thanks to Helmut Jarausch
278 <jarausch@igpm.rwth-aachen.de> for the patch and to
279 Markus Oberhumer <markus@oberhumer.com> for giving special permission
280 to include his miniLZO project (GPL licensed) in dump/restore.
281
282 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
283 <ant@notatla.demon.co.uk> for reporting the bugs.
284
285 18. Added a special rmt version which can do encryption when writing
286 to tape. Read examples/encrypted_rmt/README for details on
287 how to enable and configure it. Thanks to Ken Lalonde
288 <ken@globalremit.com> for the patch.
289
290 19. Made dump work with 2.5 kernel end of tape early warning semantics.
291 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
292
293 20. Fixed a bug which caused dump -w|-W not to work anymore, because
294 the fs_freq and fs_passno fields in /etc/mtab are always set
295 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
296 reporting the bug.
297
298 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
299 =======================================================================
300
301 1. Added a note in the restore man page clarifying the question
302 'set the permissions on the current directory ?' asked by
303 restore at the end of treatment in -i and -x modes.
304
305 2. Fixed the endianess issues when reading compressed tapes.
306 Thanks to Dark Force <daq4th@users.sourceforge.net> for
307 reporting this bug and providing test cases.
308
309 3. Fixed the "ACL won't be dumped" warning message (which showed
310 an extra, unrelated error message). Thanks to Dragan Krnic
311 <dkrnic@lycos.com> for reporting this bug.
312
313 4. Made dump look first into /etc/mtab, then into /etc/fstab
314 when searching for filesystem paths. Also fixed some problems
315 caused by binding mounts or multiple block device mounts.
316 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
317 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
318 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
319 and #160305, Sourceforge bugs #618699 and #679832).
320
321 5. Made dump's -I option accept the value '0' meaning all the
322 read errors will be ignored. This can be useful when running
323 dump from unattended sessions (like cron jobs). Thanks to
324 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
325
326 6. Fixed the output of dump to indicate 'blocks' instead of
327 'tape blocks' in the various messages (blocks are always
328 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
329 made it clearly print the current blocksize at the start of
330 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
331 the suggestions.
332
333 7. Made rmt understand long (largefiles) seeks.
334
335 8. Fixed build with very old versions of libext2fs, where
336 EXT2_FT_* constants were undefined.
337
338 9. Made dump accept the dumpdates path on the command line
339 (-D file option) instead of using only the hardcoded one.
340 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
341 suggestion.
342
343 10. Enabled rmt, LFS, readline, QFA options by default in
344 ./configure. Updated the configure process (new versions
345 of config.guess, config.sub etc).
346
347 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
348 =======================================================================
349
350 1. Changed dump to use fcntl(F_SETLK) style locking instead
351 of flock() when locking the dumpdates file. With the old
352 locking scheme, a local user having read rights on the
353 dumpdates file could be able to do a Denial of Service attack
354 on dump. In order to lock the dumpdates file with the new
355 scheme, the user would need to have write access on the file.
356 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
357 reporting the bug (originally a bugtraq post).
358
359 2. Fixed interactive 'ls' which caused spurious errors warnings
360 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
361 <jorgen_ostling@users.sourceforge.net> for reporting this
362 bug.
363
364 3. Fixed dump's estimate when dealing with sparse inodes.
365
366 4. Modified dump to allow setting a blocksize bigger than 32kB
367 (raised the limit to 1024kB), because newer hardware needs
368 this for proper operation. Thanks to Dirk Traenapp
369 <dtraenapp@users.sourceforge.net> for reporting this.
370
371 5. Fixed a bug causing Dump to stop and report an error if an
372 inode number in the exclude file was followed by some amount
373 of whitespace. Thanks to Jeffrey Sofferin
374 <sofferin@users.sourceforge.net> for reporting this bug.
375
376 6. Fixed a bug which caused restore, in some particular cases,
377 to ask some 'scary' questions and leave a bunch of RSTTMP
378 directories behind when restoring incremental tapes. Thanks
379 to Philippe Troin <phil@fifi.org> for reporting this bug and
380 providing the test cases.
381
382 7. Changed the wording when inodes are excluded from dump:
383 replaced 'Added inode 7 to exclude list' with
384 'Excluding inode 7 (resize inode) from dump', as suggested
385 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
386
387 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
388 ===================================================================
389
390 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
391 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
392 <eros@lamel.bo.cnr.it> for reporting the bug.
393
394 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
395 ===================================================================
396
397 1. Made dump print out the ext2 logical block number in case of a read
398 error, which can be given as an argument to debugfs' ncheck command,
399 in order to find out the affected inode. Added note about this
400 usage in dump's man page.
401
402 2. Fixed a problem in restore when reading tapes written on big
403 endian machines with very old versions of dump. The patch was
404 contributed by George Helffrich <george@geology.bristol.ac.uk>.
405
406 3. Fixed the tape length calculation when using large tapes
407 and compression. Thanks to Georg Lippold
408 <g_lippold@sourceforge.net> for reporting the bug.
409
410 4. Added a new set of examples in dump_on_cd_2 directory, based
411 on dump_on_cd examples but somewhat enhanced, supporting DVD
412 media, and localized in english and german. Thanks to
413 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
414
415 5. Made dump save 32 bit UID/GID. Internally, this was achieved
416 by switching from the old BSD inode format to the new BSD
417 inode format, which means that the tape format was changed.
418 However, since all restore versions out there should
419 transparently support both inode formats, the change should
420 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
421 reporting the bug.
422
423 6. Fixed a lot of warnings in the code shown when compiling
424 with 'gcc -W'. Thanks to Matthias Andree
425 <matthias.andree@stud.uni-dortmund.de> for reporting this.
426
427 7. Fixed a small markup bug in the dump man page. Thanks to
428 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
429 patch.
430
431 8. Rewrote entirely the man pages using the tmac.an macro
432 package (Linux man page format) instead of the original BSD
433 format. They should be now cleaner and easier to modify.
434
435 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
436 ==================================================================
437
438 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
439 non Linux clients were misinterpreted. The description of the problem
440 (incompatible numbering in Linux mtio opcodes) is documented at
441 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
442 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
443 providing an excellent, cross-platform replacement for rmt in his
444 star package.
445
446 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
447 which caused restore to fail when the inode maps were not entirely
448 contained on the first volume (when using really small volumes or
449 when dumping a huge number of inodes).
450
451 3. Fixed a problem in dump, where files in subdirectories of directories
452 that have the nodump flag set (or being excluded with -e/-E) were
453 sometimes incorrectly dumped (instead of being excluded). The original
454 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
455 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
456 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
457 help testing the patch.
458
459 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
460 which makes one able to pipe the output of dump, by the net, to
461 a remote CD-burner server.
462
463 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
464 and use GNU's symbolic syntax over rmt instead of numerical values
465 to assure multiple platform compatibility.
466
467 6. Documented the -d option in restore.
468
469 7. Added a -v (verbose) mode to dump. For now it just prints the number
470 of the inode being dumped, but this could evolve in future versions
471 to include interesting debugging output.
472
473 8. Added a -o flag to restore, which automatically restores the current
474 directory permissions in -i or -x mode, without asking the operator
475 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
476 and Peter Samuel <peters@e-smith.com>.
477
478 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
479 ====================================================================
480
481 1. Fixed a bug in the QFA feature which could have caused
482 a bad tape positionning on restore (causing extra delays in
483 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
484
485 2. Added a small note in the dump man page specifying that
486 there should be no white space between the option letter and
487 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
488
489 3. Made restore work with older versions of the readline library,
490 by checking in configure for several extended symbols. Restore
491 can now be compiled with a readline as old as the 2.0 release
492 (though it may be a good idea to upgrade it to a more recent
493 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
494 reporting the build failures.
495
496 4. Fixed a performance problem with the QFA file creation in
497 dump, which made unnecessary seeks on the tape slowing down
498 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
499 reporting this issue.
500
501 5. Removed the inclusion of some kernel headers in the dump
502 source, which prevented the compile in some kernel/glibc
503 headers/architecture combination. Thanks to Bdale Garbee
504 <bdale@gag.com> for reporting the bug.
505
506 6. Added the appropriate error message when dump fails to
507 open the output file for writing. Thanks to Amith Varghese
508 <amithv@yahoo.com> for reporting this bug.
509
510 7. Made restore able to understand large Solaris ufsdump tapes
511 (containing inodes bigger than 4194304). Sun have introduced
512 an "extension" to the dump tape format when dealing with
513 those inodes, which was uncorrectly handled by Linux restore.
514 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
515 providing a test case.
516
517 8. Added the -m parameter to dump which optimises the output for
518 inodes having been changed but not modified since the last dump
519 ('changed' and 'modified' have the meaning defined in stat(2)).
520 For those inodes, dump will save only the metadata, instead of
521 saving the entire inode contents. Inodes which are either
522 directories or have been modified since the last dump are saved
523 in a regular way. Uses of this flag must be consistent, meaning
524 that either every dump in an incremental dump set have the flag,
525 or no one has it.
526
527 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
528 =======================================================================
529
530 1. Fixed behaviour of dump when exceeding resource limits
531 (SIGXFSZ treatment).
532
533 2. Added the -L flag to restore to allow the user to specify a
534 maximal allowed number of miscompares when using restore
535 with the -C option to check the backup.
536
537 3. Detailed the manual entry for the -N option of restore.
538
539 4. Added the -a flag to restore to make able doing unattended
540 restores in -i or -x mode (automatically walks through the
541 multiple dump volumes).
542
543 5. Extended the QFA mode to work with local files and/or
544 remote tapes and files. This way, restore can know in advance
545 the tape number and the offset for the inodes to extract and
546 can minimize the extraction time by seeking directly to the
547 good tape/offset.
548
549 6. Added the -A <archive> option to both dump and restore,
550 which makes dump to archive a dump table-of-contents in
551 the specified file to be used by restore to determine
552 whether a file is in the dump file that is being restored.
553 (the archive file syntax is also compatible with the
554 Solaris ufsdump generated one).
555
556 7. Small fix in restore making it able to read some (broken ?)
557 Solaris ufsdump tapes.
558
559 8. Fixed dump to correctly recognise the root filesystem when using
560 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
561 for reporting this bug.
562
563 9. Added the -P <file> option to restore to create a
564 Quick File Access file from an already made dump. Patch
565 contributed by Uwe Gohlke <uwe@ugsoft.de>.
566
567 10. Made restore compile and run on Solaris, making it a
568 possible replacement for the standard ufsrestore. Port was
569 contributed by Uwe Gohlke <uwe@ugsoft.de>.
570
571 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
572 =====================================================================
573
574 1. Added a set of backup scripts from Eugenio Diaz
575 <getnito@yahoo.com> in the examples section. It features
576 automatic (cron based) full and incremental dumping of
577 several filesystems on a separate filesystem.
578
579 2. Fixed a off-by-one miscalculation which disabled dumping
580 a one letter subdirectory. Thanks to Chris Siebenmann
581 <cks@utcc.utoronto.ca> for reporting the bug.
582
583 3. Fixed several restore bugs occuring when trying to
584 restore some missing files on the tape. Thanks to Chris
585 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
586
587 4. Fixed --with-ldopts configure argument passing, installing from
588 a separate object directory, makefile cleanups contributed
589 by <splite@purdue.edu>.
590
591 5. Fix a bug which could caused, in some conditions, the highest
592 number inode of a filesystem, to not be dumped. Many thanks
593 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
594 chase this bug.
595
596 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
597 =======================================================================
598
599 1. Added a mini howto from Patrick Walsh in the examples
600 directory.
601
602 2. Minor man pages syntax corrections. Thanks to
603 Chris Danis <screechco@home.com> for reporting the bugs.
604
605 3. Added a script from David B. Peterson <dave@toppledwagon.com>
606 to the examples section. It features dumping several
607 filesystems to a remote tape drive upon ssh.
608
609 4. Added a patch provided by Richard Jones <rich@annexia.org>
610 which allows BRADEMAX (number of read errors tolerated by
611 dump) to be adjusted using the -I option.
612
613 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
614 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
615 patch.
616
617 6. Add the -l option to restore to specify if, when doing a
618 remote restore, the file used to access the backup is a
619 regular file (the defaults being a tape drive). Restore needs
620 to know this information when reading a remote compressed
621 dump. Previously, this information was autodetected, but
622 the autodetection code fails (with ioctl: Inappropriate ioctl
623 for device) when using a non Linux remote box. Thanks to
624 many users and especially to Eros Albertazzi
625 <eros@lamel.bo.cnr.it> for reporting this.
626
627 7. Found a workaroung for the dump deadlock problem (3 childs
628 stuck in pause(), father in read()). The workaround seems
629 to work for me and several beta-testers. If it doesn't work
630 for you, please report back.
631
632 8. Updated the RPM spec file (BuildPrereq, URL etc).
633
634 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
635 ========================================================================
636
637 1. Fixed the permissions of a newly created QFA file by dump.
638
639 2. Cleaned up the source of dump (the external variables
640 definition was a complete mess, making possible to have
641 objects overlap).
642
643 3. Fixed restore to use the full tape volume path when doing
644 a compare (since it changes the working directory to the
645 filesystem being compared in the process).
646
647 4. Added the -q option to dump which makes dump abort
648 whenever it needs operator attention. It should be
649 easier to use dump in scripts with this option.
650
651 5. Detect the use of incompatible options to dump and
652 refuse them (like -a and -B options together).
653
654 6. Added bzip2 compression to dump/restore (use option -j level
655 to select it). Note that you will need a restore version
656 >= 0.4b24 in order to restore a bzip2 compressed dump.
657 The same warning as for the zlib compression applies:
658 the tape format of a bzip2 dump is not compatible with the
659 original BSD tape format.
660
661 7. Fixed a overflow problem in dump corrupting the dump when
662 very large files were encountered. Thanks to Vladimir Nadvornik
663 for the bug report.
664
665 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
666 kernel buffer/page cache before starting the dump, helping
667 a bit those who use dump on mounted filesystems. Thanks to
668 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
669 for this suggestion.
670
671 9. Updated the RPM spec file following the RedHat changes
672 (dynamically linked binaries now in /usr/sbin etc).
673
674 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
675 which enables restore to recognise multi volume compressed dumps
676 done on CD. Included his scripts for dump (which pipe the dump
677 output directly into cdrecord) and restore. There is now
678 possible to to backups to CD on the fly!
679
680 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
681 ===================================================================
682
683 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
684 Marcus Meissner (Caldera International Security Dept.).
685
686 2. Implement the Sun rmt extended protocol. Patch submitted
687 by Ian Gordon <iangordon@users.sourceforge.net>.
688
689 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
690 the linux kernel header. This ensures that dump always has the
691 latest version of this file. Patch submitted by
692 Andreas Dilger <adilger@turbolinux.com>.
693
694 4. Report any filesystem present in either /etc/fstab with a
695 positive passno or /etc/dumpdates in dump -w output.
696 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
697
698 5. Fixed the looping problem in dump introduced in the
699 previous version.
700
701 6. Changed the -B option of dump to limit the size of
702 _compressed_ output per volume if compression is on.
703 Patch contributed by Helmut Jarausch
704 <jarausch@igpm.rwth-aachen.de>. Note however that, since
705 it is impossible to predict the size of the compressed
706 data before doing the compression, the -B limit is a bit
707 conservative.
708
709 7. Fixed a bug in reading the operator typed file/tape path for
710 the next volume in restore.
711
712 8. Implemented a "-F script" option to restore which permits the
713 user to specify a script which will be launched at the
714 beginning of each tape, useful for automatic programming of
715 tape changers for example. See the restore man page for the
716 script parameters and return codes.
717
718 9. Small fix for the QFA routines provided by Uwe Gohlke
719 <uwe@ugsoft.de>, and some recommendations for QFA uses in
720 the man pages.
721
722 10. Fixed the multivolume restoring where making a mistake
723 to the 'Mount next tape' prompt caused several blocks to
724 be lost.
725
726 11. Enhanced the -e option of dump to take as a parameter a
727 comma separated list of inode numbers.
728
729 12. Added the -E option to dump which specify a file containing
730 inode numbers to exclude from the dump.
731
732 13. Fixed the compressed multi-volume dump + restore.
733
734 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
735 ==================================================================
736
737 1. Made dump report the number of blocks dumped per volume.
738 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
739
740 2. Fix a bug in dump where waiting too much at the 'change volumes'
741 question caused the volume to be rewritten. Thanks to
742 Graham Reed <greed@users.sourceforge.net> for reporting the
743 bug and providing a patch.
744
745 3. Added a compression option to dump, contributed by Jerry
746 Peters <gapeters@worldnet.att.net>.
747
748 WARNING: the compression works only on files/pipes and
749 drives supporting variable block size.
750
751 WARNING2: tapes created using the compression feature are
752 incompatible with the standard dump tape format, and a
753 version of restore >= 0.4b22 will be needed for extraction.
754
755 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
756 architectures. Thanks to Paul Slootman <paul@debian.org> for
757 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
758 it upstream.
759
760 5. Many cleanups (CPP defines, const char warnings, check of
761 ext2fs COMPAT flags, time_t cleanups, added libext2 version
762 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
763
764 6. Made --prefix option work in configure. All the install path
765 are now based on the configure parameters.
766
767 7. Added the Quick File Access mode in dump/restore, contributed
768 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
769 a file tape position for each inode, and this file is used by
770 restore (if called with parameter Q and the filename)
771 to directly position the tape at the file restore is currently
772 working on. This saves hours when restoring single files from
773 large backups, saves the tapes and the drive's head. Use
774 --enable-qfa option of configure to compile in the QFA support.
775
776 8. Added the possibility to dump several files and directories
777 in a single invocation of dump. Thanks to Uwe Gohlke
778 <uwe@ugsoft.de> for implementing this option.
779
780 9. Fixed the dumping and restoring of files with holes
781 (files ending with holes didn't get dumped or restored
782 correctly).
783
784 10. Fixed a socket descriptor leak in dump, which leaved opened
785 3 file descriptors per dump process (and there is one dump
786 process per tape).
787
788 11. Fixed dump large file system support, by explicit use of
789 open64/lseek64/etc functions (explicit use needed because
790 e2fsprogs libraries don't behave well when compiled with
791 FILE_OFFSET_BITS=64).
792
793 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
794 ======================================================================
795
796 1. Fixed some bugs in the dump -w|-W logic introduced by
797 the previous version. Thanks to Andreas Dilger
798 <adilger@turbolinux.com> for his help on this one.
799
800 2. Fixed again a compilation problem when using old e2fs
801 headers (filesystem label related). Thanks to many users
802 who reported this stupid error.
803
804 3. Fixed a build problem on old lib5 based systems dealing with
805 _PATH_MNTTAB being undefined. Thanks to John Adams
806 <johna@onevista.com> for reporting the bug.
807
808 4. Improved the error detection in restore when creating
809 the temporary files in TMPDIR. Now restore will corectly
810 report a 'no space left on device' error instead of
811 strange errors which could imply an archive corruption.
812 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
813 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
814
815 5. Added the throughput information in dump's progression
816 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
817 for the patch.
818
819 6. Use libext2fs's inode scanning routines, which are particularly
820 robust when dealing with errors (especially when having some
821 bad blocks on the filesystem). Many thanks to Colin
822 <colin@horizon.com> for reporting the bug, investigating
823 the issues, finding a workaround, writing the patch and
824 fully testing it... (of course, if this patch will break
825 anything, he is to blame for :-)).
826
827 7. Made dump and restore LFS aware. Dump can dump a filesystem
828 containing large files, generate a large file on output and
829 restore can restore them. This feature is not enabled by
830 default, use --enable-largefile option of configure to enable
831 it (you need to have a LFS aware glibc though). Thanks to
832 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
833 and to Theodore T'so <tytso@valinux.com> for his always
834 useful thoughts.
835
836 8. Made dump ask upon a tape write error if it should rewrite
837 the current volume (assume this is a bad tape) or if it should
838 assume an end-of-tape condition (useful for tape drives which
839 behaves badly at the end of the tape). Thanks to Andreas
840 Dilger <adilger@turbolinux.com> for the suggestion.
841
842 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
843 =======================================================================
844
845 1. Fixed a small compilation problem due to a change
846 in the definintion of the struct sigaction in
847 glibc 2.0 / libc5. Thanks to Gunther Schlegel
848 <schlegel@riege.de> for reporting the bug and to
849 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
850 a fix.
851
852 2. Modified the label and uuid analysis in order to be
853 self-contained (independant of kernel/libc headers). This
854 should fix the compile with older kernel/libc headers and
855 will preserve the functionality. Thanks to Bernhard Erdmann
856 <bernhard.erdmann@gmx.de> for reporting the bug.
857
858 3. The 'exclude inode' option, if applied to a directory
859 inode, excludes now correctly all the leaves of this
860 directory. Thanks to John R. Dennison
861 <gerdesas@users.sourceforge.net> for reporting the bug.
862
863 4. Fixed the '-e' option to disable the possibility
864 to exclude the root inode (which causes the dumps to
865 be unreadable by restore). Prevented array overflow
866 when multiple -e options are used.
867
868 5. Fixed dump to correctly interpret a filesystem argument
869 which is a mountpoint and it is not an absolute path
870 (as specified in the fstab). Thanks to Bernhard R. Erdmann
871 <be@berdmann.de> for reporting the bug.
872
873 6. Made dump able to backup files larger than 2 GB. Note that
874 dump still doesn't cope with files larger than 4 GB.
875
876 7. Restore the real uid and gid before invoking an external
877 RSH program (big hole when dump or restore is suid root!).
878
879 8. Get the values for the default tape device and the location
880 of fstab file from the system headers. Thanks to
881 Andreas Dilger <adilger@turbolinux.com> for the patch.
882
883 9. Made dump -w|-W report all recognized filesystems
884 present in either /etc/fstab or /etc/dumpdates, and present
885 the list in the same order as in fstab file. Thanks
886 to Andreas Dilger <adilger@turbolinux.com> for the patch.
887
888 10. Made dump's -a (automatic end of tape detection) the
889 default. Specifying one of -B, -c, -d or -s options will
890 override the EOM detection. Thanks to Andreas Dilger
891 <adilger@turbolinux.com> for the patch.
892
893 11. Save the ext2 filesystem label into the dump volume label.
894 Specifying a volume label on the command line (-L option)
895 will override this feature. Thanks to Andreas Dilger
896 <adilger@turbolinux.com> for the patch.
897
898 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
899 =====================================================================
900
901 1. Fixed the signal handling in dump (which I broke in 0.4b17)
902 which was causing several strange dump failures (dump
903 hanged or segmentation faults etc).
904
905 2. Specified the default blocksize in the dump man page.
906
907 3. Changed two info messages of restore to be written on stdout
908 instead of stderr in order to leave stderr only for errors
909 or warnings. Thanks to Stephen Atwell
910 <satwell@urbana.css.mot.com> for the suggestion.
911
912 4. Corrected an off by one calculation which prevented
913 dumping a directory having a 1 character name length.
914 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
915 for reporting the bug.
916
917 5. Reinforce dump in order to allow only level 0 and no
918 -u option when dumping a subdirectory, and document
919 this in the man page. Thanks to Bernhard Erdmann
920 <bernhard.erdmann@gmx.de> for reporting the bug.
921
922 6. Fixed a small harmless bug in restore which caused
923 in some conditions hard links to be restored several
924 times (therefore generation some warning messages).
925 Thanks to Kenneth Porter <shiva@well.com> for
926 reporting the bug.
927
928 7. Updated the RPM spec file to the latest RedHat version,
929 providing FHS packaging and other cosmetic changes.
930 You will need RPM version >= 3.0.5 in order to build the RPM.
931
932 8. Updated the configure script to check for libtermcap
933 before checking for libreadline, because we need this
934 library in order to compile the readline support.
935
936 9. Made dump understand the LABEL= and UUID= notation
937 both in /etc/fstab and on the command line. Note that
938 you will need the /proc filesystem in order to use
939 these notations. Thanks to Erik Troan <ewt@redhat.com>
940 for providing the patch.
941
942 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
943 ===================================================================
944
945 1. Fixed a potential buffer overflow in restore. Thanks
946 to Stan Bubrouski <satan@fastdial.net> for reporting
947 the bug.
948
949 2. Fixed a readline-related bug which prevented
950 'cat DUMPFILE | restore -i -f -' from working. Thanks
951 to Charles Karney <karney@users.sourceforge.net>
952 for the bug report.
953
954 3. Changed a few "panic" into "exit", causing restore to
955 be more stable against some attacks (like the last one
956 reported on Bugtraq, although the last version of restore
957 was not vulnerable - just dumped core). Thanks to
958 Andreas Hasenack <andreas@conectiva.com.br> for reporting
959 the bugs to me.
960
961 4. Removed the suid-root bit on dump and restore in the
962 default build (and generated RPMs). It should be safer
963 now. Users who need the suid-root capabilities in order
964 to make network backups should read first the man page
965 of dump and enable the suid bit manually.
966
967 5. Added -ltermcap to the compile parameters for restore
968 when using readline support, in order to make the compile
969 process work on some systems (SuSE ?). Thanks to
970 Patrik Schindler <poc@pocnet.net> for reporting the bug.
971
972 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
973 ====================================================================
974
975 1. The -F script is called now *only* at the end of a tape,
976 not at the end of the dump. Thanks to Christian Haul
977 <haul@informatik.tu-darmstadt.de> for the bug report.
978
979 Normally, the device name and the current volume number
980 are passed on the command line of the script. However,
981 if you want the old style script (with no arguments
982 passed on the command line), you can enable it in
983 configure with the --enable-oldstylefscript.
984
985 2. Use posix signal handling to preserve dump functionality
986 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
987 the patch.
988
989 3. Made the exit code of restore in case of a 'C'ompare
990 command reflect the result of the compare. An exit status
991 of 0 means the dump archive is correct, 1 means tape errors,
992 2 means that some files were modified. Thanks to Kenneth Porter
993 <shiva@well.com> for the suggestion.
994
995 4. Made (finally) quotes work in interactive restore.
996
997 5. Small fixes in order to allow dump to compile with a
998 really old e2fsprogs version. Thanks to Ian Zimmerman
999 <itz@speakeasy.org> for the bug report.
1000
1001 6. Add GNU readline capabilities to interactive restore.
1002 Use configure's --enable-readline flag to enable this feature.
1003 Thanks to Patrik Schindler <poc@pocnet.net> for the
1004 suggestion.
1005
1006 7. Do the compare on the fly in restore 'C' mode (this will
1007 allow not to exhaust the available /tmp space when
1008 ccmparing large files). Thanks to Kenneth Porter
1009 <shiva@well.com> for the suggestion.
1010
1011 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
1012 ====================================================================
1013
1014 1. Fixed some several duplicate 'DUMP: DUMP:' in the
1015 output of dump.
1016
1017 2. Corrected the estimation of blocks to dump. Note that
1018 this is still wrong for large directory inodes, due
1019 to the size of a BSD directory entry on the tape
1020 (estimation is based on the size of the ext2 directory,
1021 which is smaller because it doesn't contain the null
1022 character at the end).
1023
1024 3. Made dump report the total number of MB written to
1025 tape at the end of run. Thanks to W. Reilly Cooley
1026 <wcooley@nakedape.cc> for the patch.
1027
1028 4. Added the -X option to restore giving the possibility
1029 to read the names of the files to be extracted/listed
1030 from a text file (in addition of the command line).
1031 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
1032 patch.
1033
1034 5. Added the device name and the current volume number
1035 as arguments to the end of tape script (dump -F option).
1036
1037 6. Made the multi-volume dump work again (after having
1038 broken it in 0.4b15).
1039
1040 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1041 ===================================================================
1042
1043 1. Added a prompt command in interactive restore mode. Thanks
1044 to Andreas Dilger <adilger@home.com> for the patch.
1045
1046 2. Fixed a buffer overflow problem in dump (caused by
1047 not checking the size of the filesystem parameter).
1048 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1049 reporting this on Bugtraq (and to several dump users
1050 who forwarded me his mail).
1051
1052 3. Added the '-F script' option to dump in order to
1053 launch a script at the end of each tape (to be used
1054 with a tape changer, or to notify the sysadmin by
1055 pager etc.).
1056
1057 4. Fixed a bug in restore compare code caused by the changes
1058 I made in 0.4b14.
1059
1060 5. Fixed the treatment of options using the old BSD syntax
1061 in both dump and restore.
1062
1063 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1064 =======================================================================
1065
1066 1. Fixed a bug in dump which may have caused invalid deleted
1067 directories to be dumped out if they were deleted after the
1068 mapping pass. This could occure on active filesystem and lead
1069 to heap corruption (causing dump malfunction in many possible ways).
1070 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1071 bug and submitting the patch.
1072
1073 2. Fixed the handling of the filesystem parameter in dump. A
1074 '/mnt/disk' parameter caused the disk contents to be dumped,
1075 but a '/mnt/disk/' parameter caused the mountpoint directory
1076 to be dumped (generally an empty directory).
1077
1078 3. Improved the output of dump in order to tell which directory
1079 it is currently dumping (when dumping a subtree).
1080
1081 4. Added the '-e' exclude inode option to dump. Thanks to
1082 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1083
1084 5. Added a REPORTING-BUGS file in order to provide a guide
1085 on how to correctly report a bug in dump/restore.
1086
1087 6. Fixed a restore problem when restoring a hard link to an inode
1088 having the immutable or append-only attribute set. Thanks to
1089 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1090
1091 7. Fixed a compatibility problem between dumps made on little
1092 endian machines (the format was correct) and big endian
1093 machines (the format was incorrect). This fix break the
1094 compatibility with the older dumps made on big endian
1095 machines (sparc, m86k, ppc etc). For the first time in
1096 linux dump's history (I believe), the dumps made by *BSD,
1097 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1098 so interchangeable. Thanks to Rob Cermak
1099 <cermak@ahab.rutgers.edu> for submitting the bug and
1100 helping me test the fix.
1101
1102 8. Fixed the way dump reports the remaining percent/time, if
1103 the number of blocks actually dumped exceeds the estimated
1104 number of blocks. Thanks to Jean-Paul van der Jagt
1105 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1106
1107 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1108 ======================================================================
1109
1110 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1111 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1112
1113 2. Removed the requirement to build the RPM as root from the
1114 spec file. Thanks to Christian Weisgerber
1115 <naddy@mips.rhein-neckar.de> for submitting this.
1116
1117 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1118 causing dump to block when dumping really huge filesystems.
1119 Many thanks to Patrik Schindler <poc@pocnet.net> for
1120 helping me find this bug.
1121
1122 4. Fixed the treatment for an interrupt signal when dump access
1123 the remote tape through RSH. Thanks to Christian Weisgerber
1124 <naddy@mips.rhein-neckar.de> for providing the patch.
1125
1126 5. Fixed a bug which was causing dump/restore to display
1127 garbage characters instead of the remote host name.
1128
1129 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1130 =====================================================================
1131
1132 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1133 <kukuk@suse.de> for submitting the patch.
1134
1135 2. Fix for the exit code when using the size estimate option of
1136 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1137 submitting the patch.
1138
1139 3. Handle EINTR in atomical reads/writes in dump, which was causing
1140 dump to fail on some systems. Thanks to Eric Jergensen
1141 <eric@dvns.com> for reporting the bug and submitting the patch.
1142
1143 4. Handle more than 16 characters for the device names in dumpdates.
1144 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1145 tracking down the problem and proposing the solution.
1146
1147 5. Fixed a bug in dump which prevented the creation of the
1148 dumpdates file when doing a 0-level dump without already
1149 having a dumpdates file. Thanks to Patrik Schindler
1150 <poc@pocnet.net> for reporting the bug.
1151
1152 6. Changed the way dump 'S' flag reports the size estimate
1153 from number of blocks into bytes (making it compatible
1154 with the Solaris version, and simplifying things for
1155 amanda users). Thanks to Jason L Tibbitts III
1156 <tibbs@math.uh.edu> for reporting the bug.
1157
1158 7. Fixed a compatibility problem in linux/alpha dump tape format.
1159 Now the linux/alpha dump are (again) compatible with the
1160 other dump formats. But this breaks compatibility with
1161 older dumps made on alpha. Thanks to Mike Tibor
1162 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1163
1164 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1165 ======================================================================
1166
1167 1. Added a '--enable-kerberos' to configure.
1168
1169 2. Added a 'S' option to dump which determines the amount of space
1170 that is needed to perform the dump without actually doing it, similar
1171 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1172 <cermak@ahab.rutgers.edu>.
1173
1174 3. Added a 'M' multi-volume option to dump and restore which enables
1175 dumping to multiple files (useful when dumping to an ext2
1176 partition to make several dump files in order to bypass the 2GB
1177 file size limitation). The 'f' argument is treated as a prefix and
1178 the output files will be named <prefix>001, <prefix>002 etc. With
1179 the 'M' flag, restore automatically selects the right file without
1180 asking to enter a new tape each time.
1181
1182 4. Fixed a memory leak which was causing dump to grow very big
1183 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1184 Fearon <jasonf@netrider.org.au> for reporting the bug.
1185
1186 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1187 ======================================================================
1188
1189 1. Make configure test if the system glob routines support
1190 extended syntax (ALTDIRFUNC). If not, use the internal glob
1191 routines instead of system ones. Thanks to Bernhard Sadlowski
1192 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1193 and helping me resolve this and other minor libc5 compiling
1194 glitches.
1195
1196 2. Fix a problem when dumping a ext2fs with the 'filetype'
1197 feature enabled. Thanks to Patrick J. LoPresti
1198 <patl@cag.lcs.mit.edu> for reporting the bug and to
1199 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1200
1201 3. Made the nodump flag work on directories. A directory which
1202 has the nodump flag gets never dumped, regardless of its
1203 contents.
1204
1205 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1206 which allows dump on an active ext3 filesystem. However, this
1207 is a "quick and dirty" patch which enables backup of an ext3
1208 filesystem through the ext2 compatibility (by ignoring the
1209 NEEDS_RECOVERY bit). The journal file is not recognized and
1210 it is dumped (it should not).
1211
1212 5. Test the superblock compatibility flags when dumping, in order
1213 to be sure that we know how to deal with specific features.
1214
1215 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1216 ====================================================================
1217
1218 1. Use lchown instead of chown, fixing a possible security problem
1219 when restoring symlinks (a malicious user could use this
1220 to deliberately corrupt the ownership of important system files).
1221 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1222 this and providing the patch.
1223
1224 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1225 ====================================================================
1226
1227 1. Put dump sources under CVS, added Id tags in all files so
1228 one can use 'ident' on binary files.
1229
1230 2. Added the dump/restore version in the usage text so one can
1231 easily verify the version he is using.
1232
1233 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1234 a va_start/va_end problem on linux-ppc (always call va_start
1235 va_end in pairs each time we use a vararg function).
1236
1237 4. Added again the DT_* constants because old libc does not
1238 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1239 for submitting the bug report.
1240
1241 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1242 this should enable dumping big (huge) filesystems.
1243
1244 6. Added the RSH environment variable in order to be able to
1245 use a rsh replacement like ssh when doing remote backups (and
1246 bypass the security limitations of rcmd). Now you can do remote
1247 backups without being root (or making dump setuid root).
1248
1249 7. Modified again the way dumpdates works. For incremental dumps,
1250 we need to read dumpdates even if we are not using 'u' option.
1251 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1252 this should work.
1253
1254 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1255 ===================================================================
1256
1257 1. Removed the 'k' flag from the restore 'about' text if kerberos
1258 was not compiled in.
1259
1260 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1261 to them (fsetflags takes a char*, setflags an open fd!).
1262
1263 3. (f)setflags is called only if the flags aren't empty. If the
1264 file is a special file, a warning is printed, because changing
1265 flags implies opening the device. Normally, a special file
1266 should not have any flag... (Debian bug #29775, patch provided
1267 by Abhijit Dasgupta <abhijit@ans.net>).
1268
1269 4. Made possible to dump a file system not mentioned in /etc/fstab.
1270 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1271
1272 5. Changed the default behaviour to not create dumpdates
1273 unless 'u' option is specified. Removed the old "debian-patch"
1274 which provided the same thing. (Debian bug #38136, #33818).
1275
1276 6. Removed all those dump*announce, since they were getting old...
1277
1278 7. Added warning messages if dumpdates does not exist and
1279 when an inferior level dump does not exist (except for a level 0
1280 dump).
1281
1282 8. Debugged the glob calls in interactive mode: restore used a
1283 dirent struct which was different from the /usr/include/dirent.h
1284 one (this used to work, is it a glibc2 change?), so none of the
1285 compat glob (which used /usr/include/dirent.h) or the system glob
1286 worked. Restore use now the system dirent (and the system
1287 DT_* constants), which are compatible with BSD ones.
1288
1289 9. Added a configure flag (--with-dumpdatespath) to specify
1290 the location of dumpdates file. By default, it is
1291 /etc/dumpdates.
1292
1293 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1294 included the current date/version in man pages.
1295
1296 11. Corrected the estimation of remaining time when
1297 the operator doesn't change the tapes quickly enough. This
1298 was an old bug, I thought I corrected it, and discovered
1299 that in fact it was corrected in two different places, so
1300 the results canceled each other...
1301
1302 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1303 ===================================================================
1304
1305 1. Integrated multiple patches from RedHat, Debian and SuSE:
1306
1307 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1308 isn't specified.
1309 - several fixes in the man pages.
1310 - update the default tape device to /dev/st0.
1311 - many updates for Linux Alpha (byte ordering, size_t etc).
1312 - buffer overruns.
1313 - use environment variable for TMPDIR (instead of /tmp).
1314 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1315 - workaround egcs bug (RedHat bugs #4281 and #2989).
1316 - wire $(OPT) throughout Makefile's.
1317
1318 2. Upgrade the dump revision to 1, making possible to dump filesystems
1319 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1320
1321 3. Fix some compile warnings, prototype all functions.
1322
1323 4. Use glibc err/glob instead of internal compatibility
1324 routines (only if available).
1325
1326 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1327 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1328
1329 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1330 ======================================================================
1331
1332 1. Integrated the changes from FreeBSD-3.1-RELEASE
1333 (mostly bug fixes, buffer overruns, dump has now an "automatic
1334 tape length calculation" flag, dump/restore can use kerberos now
1335 (this is NOT tested), use environment variables for TAPE and
1336 RMT etc.).
1337
1338 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1339
1340 3. Corrected a bug in restore when using 'C' option with multi-volumes
1341 tapes (files splited accros two tapes give "size changed" errors
1342 when comparing).
1343
1344 4. Corrected the long standing bug when dumping multiple tapes.
1345 This works for me, needs further testing.
1346
1347 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1348 ====================================================================
1349
1350 1. Dump now runs correctly on kernels 2.1.x
1351 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1352
1353 Changes between versions 0.4b2 and 0.4b3
1354 ========================================
1355
1356 1. Use realpath() if available
1357
1358 2. Report statistics
1359
1360 Changes between versions 0.4b1 and 0.4b2
1361 ========================================
1362
1363 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1364 the patch)
1365
1366 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1367
1368 3. Fixed configure.in to correctly handle --enable-rmt
1369
1370 Changes between versions 0.3 and 0.4b1
1371 ======================================
1372
1373 1. Integrated the changes from 4.4BSD-Lite2
1374
1375 2. Integrated the patches from Debian and Red Hat
1376
1377 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1378
1379 4. Changed dump to use the Ext2fs library to get block addresses. This
1380 should solve the endianness problem on SparcLinux.
1381
1382 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1383 distribution's one) to use autoconf
1384
1385 6. Fixed a few minor bugs
1386
1387 Changes between versions 0.2e and 0.2f
1388 ======================================
1389
1390 1. Added the creation of named pipes (fifos) in restore.
1391
1392 2. Added the -N flag in the restore manual page.
1393
1394 3. Added the file kernel.patch which contains the llseek() optimization
1395 patch for 1.2.x kernels.
1396
1397 4. Fixed a bug in the restoration of symbolic links: owner and group were
1398 not restored.
1399
1400 5. Integrated some changes from FreeBSD 2.2.
1401
1402 6. Added a call to ftruncate() after restoring each file to restore
1403 correctly files ending by a hole.
1404
1405 Changes between versions 0.2d and 0.2e
1406 ======================================
1407
1408 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1409 with owner = root (0) and group = root/wheel/whatever (0).
1410
1411 Changes between versions 0.2c and 0.2d
1412 ======================================
1413
1414 1. Dump is now able to backup 2GB+ filesystems.
1415
1416 2. Dump and restore can now be linked as static binaries.
1417
1418 Changes between versions 0.2b and 0.2c
1419 ======================================
1420
1421 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1422
1423 Changes between versions 0.2a and 0.2b
1424 ======================================
1425
1426 1. Really fixed the bug that I should have corrected in 0.2a.
1427
1428 2. Enabled optimization again.
1429
1430 Changes between versions 0.2 and 0.2a
1431 =====================================
1432
1433 1. Disabled the optimization during compilation.
1434
1435 Changes between versions 0.1 and 0.2
1436 ====================================
1437
1438 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1439 the fs_type field (actually, I modified the file fstab.c to make it
1440 use the mntent functions).
1441
1442 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1443 made by dump should be readable by the BSD restore and backups made
1444 by the BSD dump should be readable by restore. Unfortunately, this
1445 means that the dump format has changed between version 0.1 and version
1446 0.2 :-(
1447
1448 3. Dump is now able to backup a subtree, it is no longer limited to whole
1449 filesystems like the BSD version.
1450
1451 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1452 than 2 GB.
1453
1454 Changes between versions 0.0 and 0.1
1455 ====================================
1456
1457 1. Now create links rdump and rrestore during the `make install' step.
1458
1459 2. Linux port specific bugs added to the manual pages
1460
1461 3. Incorrect estimation of the number of tapes blocks fixed when doing
1462 incremental backups.
1463
1464 4. Better ls-like format in restore in interactive mode.
