3 Changes between versions 0.4b42 and 0.4b43 (released ?????????????)
4 ===================================================================
5
6 1. Fix a bug in dump making impossible to handle large toc files
7 (> 2 GB). Thanks to X DUGi <xdugi@users.sourceforge.net> for
8 reporting the bug (Sourceforge bug #2820629)
9
10 2. Fix 'restore -x' in multi-volume mode, which caused files being
11 spanned on the first and second volumes to be incorrectly extracted.
12 Thanks to Adam Tkac <atkac@redhat.com> for reporting the bug.
13 (there may be several bug reports about this issue, including
14 Sourceforge bug #2117008, RedHat bugs #232415 and #444958).
15
16 3. Remove -lselinux -lsepol from the standard libraries list,
17 they shouldn't be needed if selinux is not enabled in dump
18 (this also fixes a build failure when selinux libraries are
19 not installed).
20
21 Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009)
22 ===================================================================
23
24 1. Fix printout of the 'Connection to' message in dump/restore.
25 Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
26 bug report and its fix.
27
28 2. Fix dump -w/-W output for filesystems having the last backup
29 level equal to 0. Thanks to Pascal Bouchareine
30 <kalou@users.sourceforge.net> for reporting the bug.
31
32 3. Enable restore to handle restoring onto a different SELinux
33 policy from the dump. Thanks to Tony Nelson
34 <tony_nelson@users.sourceforge.net> for the patch.
35 (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845
36 for details)
37
38 4. Fix EA set failures when restoring immutable files. Thanks
39 to Andrew Kroeger for the patch.
40
41 5. Fix "mode file too large" errors when restoring huge backups.
42 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
43 report.
44
45 6. Add the ability to link against libtinfo library if present,
46 instead of libtermcap or libncurses libraries. Thanks to
47 Adam Tkac <atkac@redhat.com> for the patch.
48
49 7. When comparing a backup, do not consider to be an error the fact
50 that we encounter files created while dump was in progress.
51 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
52 report.
53
54 8. Force '-a' to be the default value when running 'restore -C'.
55 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
56 report.
57
58 9. Many improvements to the 'cron_dump_to_disk' example.
59 Thanks to Aaron S. Hawley <ashawley@users.sourceforge.net> for
60 the patch.
61
62 10. Fix the QFA generation when extended attributes are backuped
63 along with the inodes. Prior to this fix, the entries for
64 some inodes may get corrupted (duplicated entries or incorrect
65 ones), making the QFA file unusable for repositionning in
66 restore. Many thanks to Kenneth Porter <shiva@sewingwitch.com>
67 for the bug report and the testing of the fix.
68
69 11. Fix EA restoration in debug mode (Sourceforge bug #1986216).
70
71 12. Stefan Auracher <star7@onlinehome.de> noticed that the Tower
72 of Hanoi backup strategy documented in the man page wasn't
73 actually based on the Tower of Hanoi algorithm. The man page
74 was updated accordingly.
75
76 13. Fix missing level information from dump output when using
77 the default level (RedHat bug #493635). Thanks to Adam Tkac
78 <atkac@redhat.com> for the patch.
79
80 14. Fix the dump man page to reflect the fact that the default
81 dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac
82 <atkac@redhat.com> for the patch.
83
84 15. Fixed a few spelling errors in the man pages (RedHat bug #489853).
85 Thanks to Adam Tkac <atkac@redhat.com> for the patch.
86
87 16. Fixed restore man page and program usage which incorrectly stated
88 that -P and -A were both allowed in the same invocation (RedHat
89 bug #490627). Thanks to Adam Tkac <atkac@redhat.com> for the patch.
90
91 17. Use sys_clone under Linux to share I/O contexts between dump
92 processes, thus drastically increasing the performance of dump
93 under CFQ (which is the default I/O scheduler used in a number of
94 distributions). Thanks to Jeff Moyer <jmoyer@redhat.com> for the
95 patch.
96
97 18. Add (preliminary) ext4 support - thanks to libext2fs which does
98 all the job for us. Thanks to Gertjan van Wingerde
99 <gwingerde@gmail.com> for the patch.
100
101 Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
102 =====================================================================
103
104 1. Fix restore of dumped Access Control Lists. The previous
105 code for EA works fine, but ACLs needed conversion from the
106 ext2/3 disk format to posix_acl format before restoring.
107
108 2. Fix some issues with restoration of EA on big endian
109 platforms.
110
111 3. Fix restore when the symtab is over 2GB in size.
112
113 4. Made the directory hash indexing an optional feature,
114 accessible by the '-H' option of restore, and disable it
115 by default.
116
117 5. Fixed dump to not include extended attributes information
118 in the toc (archive) file which confused restore -t.
119
120 Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
121 =================================================================
122
123 1. Changed restore to emit warnings (instead of emitting a fatal
124 error) if a file (or a directory) is unavailable for a
125 comparision (if the user doesn't have the necessary permissions
126 to access it for example). Thanks to Kenneth Porter
127 <shiva@sewingwitch.com> for the bug report.
128
129 2. Re-done the 'do not save directory entries to non-dumped inodes
130 (excluded from dump)' feature. The previous implementation
131 worked well for excluded directories but not for regular files.
132 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
133 report.
134
135 3. Fixed a bug in dump where the tape size was miscalculated when
136 the user used -d/-s to specify the tape characteristics. Thanks
137 to Philip Goisman <goisman@physics.arizona.edu> for reporting
138 the bug.
139
140 4. Fixed another bug introduced in restore with the hashtree
141 implementation. This one caused restore to stop saying
142 "removenode: non-empty directory" in some cases.
143
144 5. Added support for dumping and restoring ext2/3 extended
145 attributes (EA), like the access control lists (ACL) or
146 the security labels used by SELinux.
147
148 Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
149 ======================================================================
150
151 1. The newly added dump_on_cd_3 example was buggy, replace it
152 with an updated version from Andrew Basterfield
153 <bob@cemetery.homeunix.org>.
154
155 2. Made restore to chdir() back into the initial directory when
156 dumping core while aborting a comparision operation. The
157 previous behaviour was to write the corefile at the root of
158 the directory being compared, which could very well be
159 read only and preventing the corefile generation. Thanks
160 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
161
162 3. Silenced the failure to call fgetflags() when comparing an
163 entry which has no ext2 attributes (as in lsattr()).
164
165 4. Fix a brown paper bug in restore -C which broke restore and
166 caused modifications on the filesystem being compared
167 (directories containing a file with the same name as the
168 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
169 <shiva@sewingwitch.com> for finding the bug and helping me
170 reproduce it.
171
172 5. Made restore -C force the -N flag (no writing allowed on
173 the disk) in order to prevent more bugs like the above one.
174
175 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
176 =====================================================================
177
178 1. Fix a couple of troff syntax bugs in the man pages.
179 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
180
181 2. Made restore use either libncurses or libtermcap, depending
182 on which one is available at configure time.
183
184 3. Fixed restore negative size display bug when comparing a
185 dump containing files over 2GB. Thanks to Steve Bonds
186 <sbonds@users.sourceforge.net> for the bug report.
187
188 4. Do not save directory entries to non-dumped inodes
189 (excluded from dump). This will eliminate the 'missing
190 file' warnings when doing 'restore -C'.
191
192 5. Fix dump crash when backuping a huge (2TB) filesystem,
193 due to a bogus calculation on the inode map size.
194 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
195 submitting the bug and testing the fix.
196
197 6. Fix a problem in restore where the final \0 in the symbolic
198 link names could have been lost, generating corrupt filenames.
199 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
200 bug.
201
202 7. Implemented a hash list for the directory names in restore.
203 The linear list used before caused problems in interactive
204 restores when dealing with directories having thousands of
205 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
206 for reporting the bug.
207
208 8. Improved restore -C, this time including the directory
209 attributes into the comparision.
210
211 9. Made restore understand tapes containing EA/ACLs (which will
212 be dumped by the next version of dump). In this version
213 extended attributes on the tape are ignored, for full EA/ACL
214 support wait for the next version or try the experimental EA
215 patch.
216
217 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
218 ==================================================================
219
220 1. Added the --enable-staticz configure option which enables
221 dump and restore to be linked with static versions of
222 libz and libbz2 (and dynamic versions of all other libraries).
223 This will make Debian users happy, because libz and libbz2
224 were the only needed libraries living in /usr, all the
225 others live in /lib. In case of system emergency, it is
226 better not to have to rely on an extra filesystem.
227 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
228
229 2. Fix compilation on (at least the Linux Debian port to) AMD64.
230 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
231 that are also defined by <linux/types.h> (<asm/types.h>) and
232 they conflict).
233
234 3. Make dump's reading of the dumpdates file a bit more robust,
235 preventing dump from crashing when the dumpdates file has
236 been modified by hand.
237
238 4. Fixed some offset calculations in dump code which could
239 lead to "bread lseek errors" on large filesystems. Thanks
240 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
241 reporting this bug and debugging the issue.
242
243 5. Made dump use the blkid library when searching for devices
244 by label or uuid instead of dump's own routines.
245
246 6. Corrected a bug in dump where a wrong LABEL=... line in
247 /etc/fstab could prevent dump from dumping unrelated
248 filesystems. Thanks to Bruce Lowekamp
249 <lowekamp@users.sourceforge.net> for reporting the bug.
250
251 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
252 ====================================================================
253
254 1. Fixed dump compilation with old gcc versions. Thanks to
255 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
256
257 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
258 when compiling against a recent glibc version.
259
260 3. Fixed a bug in restore preventing the read of a dump tape
261 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
262 <phiggins@transzap.com> for reporting the bug and providing
263 the test case.
264
265 4. Changed dump to enable the creation of volumes of different
266 sizes in a single run (make -B accept a list of values).
267 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
268
269 5. Use the glibc provided minor() and major() macros instead
270 of our own bitmask implementation. This should be safe for
271 when the major/minor namespace will migrate to 32 bits.
272 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
273 the bug.
274
275 6. Made explicit in the dump man page that dump will not create
276 a remote file, it will only write to an already existing one.
277
278 7. Another try at making size estimates better again.
279
280 8. Put back the inconditional running of the end-of-tape
281 script which was changed in 0.434 to be run only when -M
282 or multiple -f were NOT specified. Some users rely on this
283 feature even when it is combined with -M/-f.
284
285 9. Fixed restore when restoring huge backups (where rstdir...
286 temporary files are over 2GB). Thanks to
287 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
288 debugging the issue and making the patch.
289
290 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
291 David <vrtin@users.sourceforge.net> for submitting the bug
292 and providing a test case.
293
294 11. Made dump work with an arbitrary integer level (no more 10
295 levels only limitation). Thanks to Matthew
296 <msvincen@midway.uchicago.edu> for the patch.
297
298 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
299 =======================================================================
300
301 1. Added a note in the dump man page saying that the default
302 blocksize can be 32 if -d is used with a high density argument.
303 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
304 for the patch.
305
306 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
307 LDFLAGS environment variables. Thanks to Arcady Genkin
308 <antipode@users.sourceforge.net> for reporting the bug.
309
310 3. Made -e/-E options of dump accept an unlimited number of inodes
311 to be excluded, rather than a hardcoded maximum. Thanks to
312 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
313
314 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
315 and -D_USE_BSD_SIGNAL defines in configure in order to solve
316 64bit build problems because quad_t is redifined with a
317 different signature. Thanks to Mike Harris <mharris@redhat.com>
318 for reporting this bug.
319
320 5. Made restore build on Solaris, making possible to
321 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
322 <uwe@ugsoft.de> for the patch.
323
324 6. Made an extension in the dump tape format capable of saving
325 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
326 wrote the extension and contributed the restore code back
327 into this codebase. The same extension mechanism will be
328 used in the future to save ACLs...
329
330 7. Made rmt work correctly with regard to QFA and local/remote
331 files and tapes. The remote access will however work only
332 when the dump provided rmt version is used. If you want to
333 use another rmt server, please do not use the QFA feature.
334 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
335
336 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
337 ====================================================================
338
339 1. Fixed the INSTALL file to reflect the actual install paths.
340 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
341 reporting the bug.
342
343 2. Fixed the configure script to only check for headers presence
344 instead of trying to compile them. This should fix issues
345 with old build environments. Thanks to Kari Lempiainen
346 <kari@funky.pp.fi> for reporting the bug.
347
348 3. Fixed restore to correctly ignore sockets when comparing
349 a dump (as socket cannot be properly restored anyway). Thanks
350 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
351
352 4. Fixed restore to correctly access the archive file (-A argument)
353 even when using a remote tape. Thanks to Fabrice Bellet
354 <fabrice@bellet.info> for reporting the bug.
355
356 5. Fixed (again) handling of long (largefile) seeks in rmt.
357 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
358 the bug.
359
360 6. Fixed restore corner case when dealing with large block sizes
361 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
362 <fabrice@bellet.info> for reporting the bug.
363
364 7. Fixed a bug preventing dump to access a filesystem having
365 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
366 for reporting the bug.
367
368 8. Made dump store dump dates using explicit timezones, fixing a
369 problem with incremental dumps if the timezone is modified
370 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
371 the bug report and the patch.
372
373 9. Fixed a bug encountered when dumping individual files (not full
374 filesystems or directories) and dangling symbolic links happen
375 to be in the list of files. For as far as dump is concerned,
376 dangling symbolic links are allowed, and are dumped as is.
377 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
378 bug and providing the fix.
379
380 10. Fixed open and creation modes and permissions for QFA and
381 table-of-contents files in dump and restore. Thanks to
382 Philippe Troin <phil@fifi.org> for the patch.
383
384 11. Fixed the archive file descriptor handling enabling it to be 0.
385 This can happen in some cases when shell redirections are used.
386 Thanks to Philippe Troin <phil@fifi.org> for the patch.
387
388 12. Delayed the opening of archive file until after suid had been
389 dropped (fixing a possible security issue if dump is suid).
390 Thanks to Philippe Troin <phil@fifi.org> for the patch.
391
392 13. Fixed the 'S' command handling in the rmt client part.
393 Thanks to Philippe Troin <phil@fifi.org> for the patch.
394
395 14. Modified the end-of-tape script handling to print out statistics
396 (and stop the timer) before launching the eot script. Also, the eot
397 script does not get run anymore when using -M (which makes sense) or
398 when multiple tapes are listed on the command line
399 (-f tape0,tape1,tapen) (which also makes sense).
400 Thanks to Philippe Troin <phil@fifi.org> for the patch.
401
402 15. Relicensed dump/restore under the 'revised' BSD license, as per
403 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
404
405 16. Added LZO compression to dump. This new compression method has
406 the advantage of being super fast, thus not killing tape streaming
407 on slow machines. Thanks to Helmut Jarausch
408 <jarausch@igpm.rwth-aachen.de> for the patch and to
409 Markus Oberhumer <markus@oberhumer.com> for giving special permission
410 to include his miniLZO project (GPL licensed) in dump/restore.
411
412 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
413 <ant@notatla.demon.co.uk> for reporting the bugs.
414
415 18. Added a special rmt version which can do encryption when writing
416 to tape. Read examples/encrypted_rmt/README for details on
417 how to enable and configure it. Thanks to Ken Lalonde
418 <ken@globalremit.com> for the patch.
419
420 19. Made dump work with 2.5 kernel end of tape early warning semantics.
421 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
422
423 20. Fixed a bug which caused dump -w|-W not to work anymore, because
424 the fs_freq and fs_passno fields in /etc/mtab are always set
425 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
426 reporting the bug.
427
428 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
429 =======================================================================
430
431 1. Added a note in the restore man page clarifying the question
432 'set the permissions on the current directory ?' asked by
433 restore at the end of treatment in -i and -x modes.
434
435 2. Fixed the endianess issues when reading compressed tapes.
436 Thanks to Dark Force <daq4th@users.sourceforge.net> for
437 reporting this bug and providing test cases.
438
439 3. Fixed the "ACL won't be dumped" warning message (which showed
440 an extra, unrelated error message). Thanks to Dragan Krnic
441 <dkrnic@lycos.com> for reporting this bug.
442
443 4. Made dump look first into /etc/mtab, then into /etc/fstab
444 when searching for filesystem paths. Also fixed some problems
445 caused by binding mounts or multiple block device mounts.
446 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
447 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
448 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
449 and #160305, Sourceforge bugs #618699 and #679832).
450
451 5. Made dump's -I option accept the value '0' meaning all the
452 read errors will be ignored. This can be useful when running
453 dump from unattended sessions (like cron jobs). Thanks to
454 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
455
456 6. Fixed the output of dump to indicate 'blocks' instead of
457 'tape blocks' in the various messages (blocks are always
458 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
459 made it clearly print the current blocksize at the start of
460 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
461 the suggestions.
462
463 7. Made rmt understand long (largefiles) seeks.
464
465 8. Fixed build with very old versions of libext2fs, where
466 EXT2_FT_* constants were undefined.
467
468 9. Made dump accept the dumpdates path on the command line
469 (-D file option) instead of using only the hardcoded one.
470 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
471 suggestion.
472
473 10. Enabled rmt, LFS, readline, QFA options by default in
474 ./configure. Updated the configure process (new versions
475 of config.guess, config.sub etc).
476
477 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
478 =======================================================================
479
480 1. Changed dump to use fcntl(F_SETLK) style locking instead
481 of flock() when locking the dumpdates file. With the old
482 locking scheme, a local user having read rights on the
483 dumpdates file could be able to do a Denial of Service attack
484 on dump. In order to lock the dumpdates file with the new
485 scheme, the user would need to have write access on the file.
486 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
487 reporting the bug (originally a bugtraq post).
488
489 2. Fixed interactive 'ls' which caused spurious errors warnings
490 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
491 <jorgen_ostling@users.sourceforge.net> for reporting this
492 bug.
493
494 3. Fixed dump's estimate when dealing with sparse inodes.
495
496 4. Modified dump to allow setting a blocksize bigger than 32kB
497 (raised the limit to 1024kB), because newer hardware needs
498 this for proper operation. Thanks to Dirk Traenapp
499 <dtraenapp@users.sourceforge.net> for reporting this.
500
501 5. Fixed a bug causing Dump to stop and report an error if an
502 inode number in the exclude file was followed by some amount
503 of whitespace. Thanks to Jeffrey Sofferin
504 <sofferin@users.sourceforge.net> for reporting this bug.
505
506 6. Fixed a bug which caused restore, in some particular cases,
507 to ask some 'scary' questions and leave a bunch of RSTTMP
508 directories behind when restoring incremental tapes. Thanks
509 to Philippe Troin <phil@fifi.org> for reporting this bug and
510 providing the test cases.
511
512 7. Changed the wording when inodes are excluded from dump:
513 replaced 'Added inode 7 to exclude list' with
514 'Excluding inode 7 (resize inode) from dump', as suggested
515 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
516
517 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
518 ===================================================================
519
520 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
521 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
522 <eros@lamel.bo.cnr.it> for reporting the bug.
523
524 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
525 ===================================================================
526
527 1. Made dump print out the ext2 logical block number in case of a read
528 error, which can be given as an argument to debugfs' ncheck command,
529 in order to find out the affected inode. Added note about this
530 usage in dump's man page.
531
532 2. Fixed a problem in restore when reading tapes written on big
533 endian machines with very old versions of dump. The patch was
534 contributed by George Helffrich <george@geology.bristol.ac.uk>.
535
536 3. Fixed the tape length calculation when using large tapes
537 and compression. Thanks to Georg Lippold
538 <g_lippold@sourceforge.net> for reporting the bug.
539
540 4. Added a new set of examples in dump_on_cd_2 directory, based
541 on dump_on_cd examples but somewhat enhanced, supporting DVD
542 media, and localized in english and german. Thanks to
543 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
544
545 5. Made dump save 32 bit UID/GID. Internally, this was achieved
546 by switching from the old BSD inode format to the new BSD
547 inode format, which means that the tape format was changed.
548 However, since all restore versions out there should
549 transparently support both inode formats, the change should
550 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
551 reporting the bug.
552
553 6. Fixed a lot of warnings in the code shown when compiling
554 with 'gcc -W'. Thanks to Matthias Andree
555 <matthias.andree@stud.uni-dortmund.de> for reporting this.
556
557 7. Fixed a small markup bug in the dump man page. Thanks to
558 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
559 patch.
560
561 8. Rewrote entirely the man pages using the tmac.an macro
562 package (Linux man page format) instead of the original BSD
563 format. They should be now cleaner and easier to modify.
564
565 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
566 ==================================================================
567
568 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
569 non Linux clients were misinterpreted. The description of the problem
570 (incompatible numbering in Linux mtio opcodes) is documented at
571 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
572 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
573 providing an excellent, cross-platform replacement for rmt in his
574 star package.
575
576 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
577 which caused restore to fail when the inode maps were not entirely
578 contained on the first volume (when using really small volumes or
579 when dumping a huge number of inodes).
580
581 3. Fixed a problem in dump, where files in subdirectories of directories
582 that have the nodump flag set (or being excluded with -e/-E) were
583 sometimes incorrectly dumped (instead of being excluded). The original
584 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
585 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
586 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
587 help testing the patch.
588
589 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
590 which makes one able to pipe the output of dump, by the net, to
591 a remote CD-burner server.
592
593 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
594 and use GNU's symbolic syntax over rmt instead of numerical values
595 to assure multiple platform compatibility.
596
597 6. Documented the -d option in restore.
598
599 7. Added a -v (verbose) mode to dump. For now it just prints the number
600 of the inode being dumped, but this could evolve in future versions
601 to include interesting debugging output.
602
603 8. Added a -o flag to restore, which automatically restores the current
604 directory permissions in -i or -x mode, without asking the operator
605 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
606 and Peter Samuel <peters@e-smith.com>.
607
608 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
609 ====================================================================
610
611 1. Fixed a bug in the QFA feature which could have caused
612 a bad tape positionning on restore (causing extra delays in
613 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
614
615 2. Added a small note in the dump man page specifying that
616 there should be no white space between the option letter and
617 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
618
619 3. Made restore work with older versions of the readline library,
620 by checking in configure for several extended symbols. Restore
621 can now be compiled with a readline as old as the 2.0 release
622 (though it may be a good idea to upgrade it to a more recent
623 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
624 reporting the build failures.
625
626 4. Fixed a performance problem with the QFA file creation in
627 dump, which made unnecessary seeks on the tape slowing down
628 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
629 reporting this issue.
630
631 5. Removed the inclusion of some kernel headers in the dump
632 source, which prevented the compile in some kernel/glibc
633 headers/architecture combination. Thanks to Bdale Garbee
634 <bdale@gag.com> for reporting the bug.
635
636 6. Added the appropriate error message when dump fails to
637 open the output file for writing. Thanks to Amith Varghese
638 <amithv@yahoo.com> for reporting this bug.
639
640 7. Made restore able to understand large Solaris ufsdump tapes
641 (containing inodes bigger than 4194304). Sun have introduced
642 an "extension" to the dump tape format when dealing with
643 those inodes, which was uncorrectly handled by Linux restore.
644 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
645 providing a test case.
646
647 8. Added the -m parameter to dump which optimises the output for
648 inodes having been changed but not modified since the last dump
649 ('changed' and 'modified' have the meaning defined in stat(2)).
650 For those inodes, dump will save only the metadata, instead of
651 saving the entire inode contents. Inodes which are either
652 directories or have been modified since the last dump are saved
653 in a regular way. Uses of this flag must be consistent, meaning
654 that either every dump in an incremental dump set have the flag,
655 or no one has it.
656
657 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
658 =======================================================================
659
660 1. Fixed behaviour of dump when exceeding resource limits
661 (SIGXFSZ treatment).
662
663 2. Added the -L flag to restore to allow the user to specify a
664 maximal allowed number of miscompares when using restore
665 with the -C option to check the backup.
666
667 3. Detailed the manual entry for the -N option of restore.
668
669 4. Added the -a flag to restore to make able doing unattended
670 restores in -i or -x mode (automatically walks through the
671 multiple dump volumes).
672
673 5. Extended the QFA mode to work with local files and/or
674 remote tapes and files. This way, restore can know in advance
675 the tape number and the offset for the inodes to extract and
676 can minimize the extraction time by seeking directly to the
677 good tape/offset.
678
679 6. Added the -A <archive> option to both dump and restore,
680 which makes dump to archive a dump table-of-contents in
681 the specified file to be used by restore to determine
682 whether a file is in the dump file that is being restored.
683 (the archive file syntax is also compatible with the
684 Solaris ufsdump generated one).
685
686 7. Small fix in restore making it able to read some (broken ?)
687 Solaris ufsdump tapes.
688
689 8. Fixed dump to correctly recognise the root filesystem when using
690 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
691 for reporting this bug.
692
693 9. Added the -P <file> option to restore to create a
694 Quick File Access file from an already made dump. Patch
695 contributed by Uwe Gohlke <uwe@ugsoft.de>.
696
697 10. Made restore compile and run on Solaris, making it a
698 possible replacement for the standard ufsrestore. Port was
699 contributed by Uwe Gohlke <uwe@ugsoft.de>.
700
701 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
702 =====================================================================
703
704 1. Added a set of backup scripts from Eugenio Diaz
705 <getnito@yahoo.com> in the examples section. It features
706 automatic (cron based) full and incremental dumping of
707 several filesystems on a separate filesystem.
708
709 2. Fixed a off-by-one miscalculation which disabled dumping
710 a one letter subdirectory. Thanks to Chris Siebenmann
711 <cks@utcc.utoronto.ca> for reporting the bug.
712
713 3. Fixed several restore bugs occuring when trying to
714 restore some missing files on the tape. Thanks to Chris
715 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
716
717 4. Fixed --with-ldopts configure argument passing, installing from
718 a separate object directory, makefile cleanups contributed
719 by <splite@purdue.edu>.
720
721 5. Fix a bug which could caused, in some conditions, the highest
722 number inode of a filesystem, to not be dumped. Many thanks
723 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
724 chase this bug.
725
726 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
727 =======================================================================
728
729 1. Added a mini howto from Patrick Walsh in the examples
730 directory.
731
732 2. Minor man pages syntax corrections. Thanks to
733 Chris Danis <screechco@home.com> for reporting the bugs.
734
735 3. Added a script from David B. Peterson <dave@toppledwagon.com>
736 to the examples section. It features dumping several
737 filesystems to a remote tape drive upon ssh.
738
739 4. Added a patch provided by Richard Jones <rich@annexia.org>
740 which allows BRADEMAX (number of read errors tolerated by
741 dump) to be adjusted using the -I option.
742
743 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
744 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
745 patch.
746
747 6. Add the -l option to restore to specify if, when doing a
748 remote restore, the file used to access the backup is a
749 regular file (the defaults being a tape drive). Restore needs
750 to know this information when reading a remote compressed
751 dump. Previously, this information was autodetected, but
752 the autodetection code fails (with ioctl: Inappropriate ioctl
753 for device) when using a non Linux remote box. Thanks to
754 many users and especially to Eros Albertazzi
755 <eros@lamel.bo.cnr.it> for reporting this.
756
757 7. Found a workaroung for the dump deadlock problem (3 childs
758 stuck in pause(), father in read()). The workaround seems
759 to work for me and several beta-testers. If it doesn't work
760 for you, please report back.
761
762 8. Updated the RPM spec file (BuildPrereq, URL etc).
763
764 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
765 ========================================================================
766
767 1. Fixed the permissions of a newly created QFA file by dump.
768
769 2. Cleaned up the source of dump (the external variables
770 definition was a complete mess, making possible to have
771 objects overlap).
772
773 3. Fixed restore to use the full tape volume path when doing
774 a compare (since it changes the working directory to the
775 filesystem being compared in the process).
776
777 4. Added the -q option to dump which makes dump abort
778 whenever it needs operator attention. It should be
779 easier to use dump in scripts with this option.
780
781 5. Detect the use of incompatible options to dump and
782 refuse them (like -a and -B options together).
783
784 6. Added bzip2 compression to dump/restore (use option -j level
785 to select it). Note that you will need a restore version
786 >= 0.4b24 in order to restore a bzip2 compressed dump.
787 The same warning as for the zlib compression applies:
788 the tape format of a bzip2 dump is not compatible with the
789 original BSD tape format.
790
791 7. Fixed a overflow problem in dump corrupting the dump when
792 very large files were encountered. Thanks to Vladimir Nadvornik
793 for the bug report.
794
795 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
796 kernel buffer/page cache before starting the dump, helping
797 a bit those who use dump on mounted filesystems. Thanks to
798 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
799 for this suggestion.
800
801 9. Updated the RPM spec file following the RedHat changes
802 (dynamically linked binaries now in /usr/sbin etc).
803
804 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
805 which enables restore to recognise multi volume compressed dumps
806 done on CD. Included his scripts for dump (which pipe the dump
807 output directly into cdrecord) and restore. There is now
808 possible to to backups to CD on the fly!
809
810 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
811 ===================================================================
812
813 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
814 Marcus Meissner (Caldera International Security Dept.).
815
816 2. Implement the Sun rmt extended protocol. Patch submitted
817 by Ian Gordon <iangordon@users.sourceforge.net>.
818
819 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
820 the linux kernel header. This ensures that dump always has the
821 latest version of this file. Patch submitted by
822 Andreas Dilger <adilger@turbolinux.com>.
823
824 4. Report any filesystem present in either /etc/fstab with a
825 positive passno or /etc/dumpdates in dump -w output.
826 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
827
828 5. Fixed the looping problem in dump introduced in the
829 previous version.
830
831 6. Changed the -B option of dump to limit the size of
832 _compressed_ output per volume if compression is on.
833 Patch contributed by Helmut Jarausch
834 <jarausch@igpm.rwth-aachen.de>. Note however that, since
835 it is impossible to predict the size of the compressed
836 data before doing the compression, the -B limit is a bit
837 conservative.
838
839 7. Fixed a bug in reading the operator typed file/tape path for
840 the next volume in restore.
841
842 8. Implemented a "-F script" option to restore which permits the
843 user to specify a script which will be launched at the
844 beginning of each tape, useful for automatic programming of
845 tape changers for example. See the restore man page for the
846 script parameters and return codes.
847
848 9. Small fix for the QFA routines provided by Uwe Gohlke
849 <uwe@ugsoft.de>, and some recommendations for QFA uses in
850 the man pages.
851
852 10. Fixed the multivolume restoring where making a mistake
853 to the 'Mount next tape' prompt caused several blocks to
854 be lost.
855
856 11. Enhanced the -e option of dump to take as a parameter a
857 comma separated list of inode numbers.
858
859 12. Added the -E option to dump which specify a file containing
860 inode numbers to exclude from the dump.
861
862 13. Fixed the compressed multi-volume dump + restore.
863
864 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
865 ==================================================================
866
867 1. Made dump report the number of blocks dumped per volume.
868 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
869
870 2. Fix a bug in dump where waiting too much at the 'change volumes'
871 question caused the volume to be rewritten. Thanks to
872 Graham Reed <greed@users.sourceforge.net> for reporting the
873 bug and providing a patch.
874
875 3. Added a compression option to dump, contributed by Jerry
876 Peters <gapeters@worldnet.att.net>.
877
878 WARNING: the compression works only on files/pipes and
879 drives supporting variable block size.
880
881 WARNING2: tapes created using the compression feature are
882 incompatible with the standard dump tape format, and a
883 version of restore >= 0.4b22 will be needed for extraction.
884
885 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
886 architectures. Thanks to Paul Slootman <paul@debian.org> for
887 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
888 it upstream.
889
890 5. Many cleanups (CPP defines, const char warnings, check of
891 ext2fs COMPAT flags, time_t cleanups, added libext2 version
892 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
893
894 6. Made --prefix option work in configure. All the install path
895 are now based on the configure parameters.
896
897 7. Added the Quick File Access mode in dump/restore, contributed
898 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
899 a file tape position for each inode, and this file is used by
900 restore (if called with parameter Q and the filename)
901 to directly position the tape at the file restore is currently
902 working on. This saves hours when restoring single files from
903 large backups, saves the tapes and the drive's head. Use
904 --enable-qfa option of configure to compile in the QFA support.
905
906 8. Added the possibility to dump several files and directories
907 in a single invocation of dump. Thanks to Uwe Gohlke
908 <uwe@ugsoft.de> for implementing this option.
909
910 9. Fixed the dumping and restoring of files with holes
911 (files ending with holes didn't get dumped or restored
912 correctly).
913
914 10. Fixed a socket descriptor leak in dump, which leaved opened
915 3 file descriptors per dump process (and there is one dump
916 process per tape).
917
918 11. Fixed dump large file system support, by explicit use of
919 open64/lseek64/etc functions (explicit use needed because
920 e2fsprogs libraries don't behave well when compiled with
921 FILE_OFFSET_BITS=64).
922
923 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
924 ======================================================================
925
926 1. Fixed some bugs in the dump -w|-W logic introduced by
927 the previous version. Thanks to Andreas Dilger
928 <adilger@turbolinux.com> for his help on this one.
929
930 2. Fixed again a compilation problem when using old e2fs
931 headers (filesystem label related). Thanks to many users
932 who reported this stupid error.
933
934 3. Fixed a build problem on old lib5 based systems dealing with
935 _PATH_MNTTAB being undefined. Thanks to John Adams
936 <johna@onevista.com> for reporting the bug.
937
938 4. Improved the error detection in restore when creating
939 the temporary files in TMPDIR. Now restore will corectly
940 report a 'no space left on device' error instead of
941 strange errors which could imply an archive corruption.
942 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
943 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
944
945 5. Added the throughput information in dump's progression
946 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
947 for the patch.
948
949 6. Use libext2fs's inode scanning routines, which are particularly
950 robust when dealing with errors (especially when having some
951 bad blocks on the filesystem). Many thanks to Colin
952 <colin@horizon.com> for reporting the bug, investigating
953 the issues, finding a workaround, writing the patch and
954 fully testing it... (of course, if this patch will break
955 anything, he is to blame for :-)).
956
957 7. Made dump and restore LFS aware. Dump can dump a filesystem
958 containing large files, generate a large file on output and
959 restore can restore them. This feature is not enabled by
960 default, use --enable-largefile option of configure to enable
961 it (you need to have a LFS aware glibc though). Thanks to
962 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
963 and to Theodore T'so <tytso@valinux.com> for his always
964 useful thoughts.
965
966 8. Made dump ask upon a tape write error if it should rewrite
967 the current volume (assume this is a bad tape) or if it should
968 assume an end-of-tape condition (useful for tape drives which
969 behaves badly at the end of the tape). Thanks to Andreas
970 Dilger <adilger@turbolinux.com> for the suggestion.
971
972 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
973 =======================================================================
974
975 1. Fixed a small compilation problem due to a change
976 in the definintion of the struct sigaction in
977 glibc 2.0 / libc5. Thanks to Gunther Schlegel
978 <schlegel@riege.de> for reporting the bug and to
979 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
980 a fix.
981
982 2. Modified the label and uuid analysis in order to be
983 self-contained (independant of kernel/libc headers). This
984 should fix the compile with older kernel/libc headers and
985 will preserve the functionality. Thanks to Bernhard Erdmann
986 <bernhard.erdmann@gmx.de> for reporting the bug.
987
988 3. The 'exclude inode' option, if applied to a directory
989 inode, excludes now correctly all the leaves of this
990 directory. Thanks to John R. Dennison
991 <gerdesas@users.sourceforge.net> for reporting the bug.
992
993 4. Fixed the '-e' option to disable the possibility
994 to exclude the root inode (which causes the dumps to
995 be unreadable by restore). Prevented array overflow
996 when multiple -e options are used.
997
998 5. Fixed dump to correctly interpret a filesystem argument
999 which is a mountpoint and it is not an absolute path
1000 (as specified in the fstab). Thanks to Bernhard R. Erdmann
1001 <be@berdmann.de> for reporting the bug.
1002
1003 6. Made dump able to backup files larger than 2 GB. Note that
1004 dump still doesn't cope with files larger than 4 GB.
1005
1006 7. Restore the real uid and gid before invoking an external
1007 RSH program (big hole when dump or restore is suid root!).
1008
1009 8. Get the values for the default tape device and the location
1010 of fstab file from the system headers. Thanks to
1011 Andreas Dilger <adilger@turbolinux.com> for the patch.
1012
1013 9. Made dump -w|-W report all recognized filesystems
1014 present in either /etc/fstab or /etc/dumpdates, and present
1015 the list in the same order as in fstab file. Thanks
1016 to Andreas Dilger <adilger@turbolinux.com> for the patch.
1017
1018 10. Made dump's -a (automatic end of tape detection) the
1019 default. Specifying one of -B, -c, -d or -s options will
1020 override the EOM detection. Thanks to Andreas Dilger
1021 <adilger@turbolinux.com> for the patch.
1022
1023 11. Save the ext2 filesystem label into the dump volume label.
1024 Specifying a volume label on the command line (-L option)
1025 will override this feature. Thanks to Andreas Dilger
1026 <adilger@turbolinux.com> for the patch.
1027
1028 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
1029 =====================================================================
1030
1031 1. Fixed the signal handling in dump (which I broke in 0.4b17)
1032 which was causing several strange dump failures (dump
1033 hanged or segmentation faults etc).
1034
1035 2. Specified the default blocksize in the dump man page.
1036
1037 3. Changed two info messages of restore to be written on stdout
1038 instead of stderr in order to leave stderr only for errors
1039 or warnings. Thanks to Stephen Atwell
1040 <satwell@urbana.css.mot.com> for the suggestion.
1041
1042 4. Corrected an off by one calculation which prevented
1043 dumping a directory having a 1 character name length.
1044 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
1045 for reporting the bug.
1046
1047 5. Reinforce dump in order to allow only level 0 and no
1048 -u option when dumping a subdirectory, and document
1049 this in the man page. Thanks to Bernhard Erdmann
1050 <bernhard.erdmann@gmx.de> for reporting the bug.
1051
1052 6. Fixed a small harmless bug in restore which caused
1053 in some conditions hard links to be restored several
1054 times (therefore generation some warning messages).
1055 Thanks to Kenneth Porter <shiva@well.com> for
1056 reporting the bug.
1057
1058 7. Updated the RPM spec file to the latest RedHat version,
1059 providing FHS packaging and other cosmetic changes.
1060 You will need RPM version >= 3.0.5 in order to build the RPM.
1061
1062 8. Updated the configure script to check for libtermcap
1063 before checking for libreadline, because we need this
1064 library in order to compile the readline support.
1065
1066 9. Made dump understand the LABEL= and UUID= notation
1067 both in /etc/fstab and on the command line. Note that
1068 you will need the /proc filesystem in order to use
1069 these notations. Thanks to Erik Troan <ewt@redhat.com>
1070 for providing the patch.
1071
1072 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
1073 ===================================================================
1074
1075 1. Fixed a potential buffer overflow in restore. Thanks
1076 to Stan Bubrouski <satan@fastdial.net> for reporting
1077 the bug.
1078
1079 2. Fixed a readline-related bug which prevented
1080 'cat DUMPFILE | restore -i -f -' from working. Thanks
1081 to Charles Karney <karney@users.sourceforge.net>
1082 for the bug report.
1083
1084 3. Changed a few "panic" into "exit", causing restore to
1085 be more stable against some attacks (like the last one
1086 reported on Bugtraq, although the last version of restore
1087 was not vulnerable - just dumped core). Thanks to
1088 Andreas Hasenack <andreas@conectiva.com.br> for reporting
1089 the bugs to me.
1090
1091 4. Removed the suid-root bit on dump and restore in the
1092 default build (and generated RPMs). It should be safer
1093 now. Users who need the suid-root capabilities in order
1094 to make network backups should read first the man page
1095 of dump and enable the suid bit manually.
1096
1097 5. Added -ltermcap to the compile parameters for restore
1098 when using readline support, in order to make the compile
1099 process work on some systems (SuSE ?). Thanks to
1100 Patrik Schindler <poc@pocnet.net> for reporting the bug.
1101
1102 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
1103 ====================================================================
1104
1105 1. The -F script is called now *only* at the end of a tape,
1106 not at the end of the dump. Thanks to Christian Haul
1107 <haul@informatik.tu-darmstadt.de> for the bug report.
1108
1109 Normally, the device name and the current volume number
1110 are passed on the command line of the script. However,
1111 if you want the old style script (with no arguments
1112 passed on the command line), you can enable it in
1113 configure with the --enable-oldstylefscript.
1114
1115 2. Use posix signal handling to preserve dump functionality
1116 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
1117 the patch.
1118
1119 3. Made the exit code of restore in case of a 'C'ompare
1120 command reflect the result of the compare. An exit status
1121 of 0 means the dump archive is correct, 1 means tape errors,
1122 2 means that some files were modified. Thanks to Kenneth Porter
1123 <shiva@well.com> for the suggestion.
1124
1125 4. Made (finally) quotes work in interactive restore.
1126
1127 5. Small fixes in order to allow dump to compile with a
1128 really old e2fsprogs version. Thanks to Ian Zimmerman
1129 <itz@speakeasy.org> for the bug report.
1130
1131 6. Add GNU readline capabilities to interactive restore.
1132 Use configure's --enable-readline flag to enable this feature.
1133 Thanks to Patrik Schindler <poc@pocnet.net> for the
1134 suggestion.
1135
1136 7. Do the compare on the fly in restore 'C' mode (this will
1137 allow not to exhaust the available /tmp space when
1138 ccmparing large files). Thanks to Kenneth Porter
1139 <shiva@well.com> for the suggestion.
1140
1141 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
1142 ====================================================================
1143
1144 1. Fixed some several duplicate 'DUMP: DUMP:' in the
1145 output of dump.
1146
1147 2. Corrected the estimation of blocks to dump. Note that
1148 this is still wrong for large directory inodes, due
1149 to the size of a BSD directory entry on the tape
1150 (estimation is based on the size of the ext2 directory,
1151 which is smaller because it doesn't contain the null
1152 character at the end).
1153
1154 3. Made dump report the total number of MB written to
1155 tape at the end of run. Thanks to W. Reilly Cooley
1156 <wcooley@nakedape.cc> for the patch.
1157
1158 4. Added the -X option to restore giving the possibility
1159 to read the names of the files to be extracted/listed
1160 from a text file (in addition of the command line).
1161 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
1162 patch.
1163
1164 5. Added the device name and the current volume number
1165 as arguments to the end of tape script (dump -F option).
1166
1167 6. Made the multi-volume dump work again (after having
1168 broken it in 0.4b15).
1169
1170 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1171 ===================================================================
1172
1173 1. Added a prompt command in interactive restore mode. Thanks
1174 to Andreas Dilger <adilger@home.com> for the patch.
1175
1176 2. Fixed a buffer overflow problem in dump (caused by
1177 not checking the size of the filesystem parameter).
1178 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1179 reporting this on Bugtraq (and to several dump users
1180 who forwarded me his mail).
1181
1182 3. Added the '-F script' option to dump in order to
1183 launch a script at the end of each tape (to be used
1184 with a tape changer, or to notify the sysadmin by
1185 pager etc.).
1186
1187 4. Fixed a bug in restore compare code caused by the changes
1188 I made in 0.4b14.
1189
1190 5. Fixed the treatment of options using the old BSD syntax
1191 in both dump and restore.
1192
1193 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1194 =======================================================================
1195
1196 1. Fixed a bug in dump which may have caused invalid deleted
1197 directories to be dumped out if they were deleted after the
1198 mapping pass. This could occure on active filesystem and lead
1199 to heap corruption (causing dump malfunction in many possible ways).
1200 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1201 bug and submitting the patch.
1202
1203 2. Fixed the handling of the filesystem parameter in dump. A
1204 '/mnt/disk' parameter caused the disk contents to be dumped,
1205 but a '/mnt/disk/' parameter caused the mountpoint directory
1206 to be dumped (generally an empty directory).
1207
1208 3. Improved the output of dump in order to tell which directory
1209 it is currently dumping (when dumping a subtree).
1210
1211 4. Added the '-e' exclude inode option to dump. Thanks to
1212 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1213
1214 5. Added a REPORTING-BUGS file in order to provide a guide
1215 on how to correctly report a bug in dump/restore.
1216
1217 6. Fixed a restore problem when restoring a hard link to an inode
1218 having the immutable or append-only attribute set. Thanks to
1219 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1220
1221 7. Fixed a compatibility problem between dumps made on little
1222 endian machines (the format was correct) and big endian
1223 machines (the format was incorrect). This fix break the
1224 compatibility with the older dumps made on big endian
1225 machines (sparc, m86k, ppc etc). For the first time in
1226 linux dump's history (I believe), the dumps made by *BSD,
1227 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1228 so interchangeable. Thanks to Rob Cermak
1229 <cermak@ahab.rutgers.edu> for submitting the bug and
1230 helping me test the fix.
1231
1232 8. Fixed the way dump reports the remaining percent/time, if
1233 the number of blocks actually dumped exceeds the estimated
1234 number of blocks. Thanks to Jean-Paul van der Jagt
1235 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1236
1237 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1238 ======================================================================
1239
1240 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1241 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1242
1243 2. Removed the requirement to build the RPM as root from the
1244 spec file. Thanks to Christian Weisgerber
1245 <naddy@mips.rhein-neckar.de> for submitting this.
1246
1247 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1248 causing dump to block when dumping really huge filesystems.
1249 Many thanks to Patrik Schindler <poc@pocnet.net> for
1250 helping me find this bug.
1251
1252 4. Fixed the treatment for an interrupt signal when dump access
1253 the remote tape through RSH. Thanks to Christian Weisgerber
1254 <naddy@mips.rhein-neckar.de> for providing the patch.
1255
1256 5. Fixed a bug which was causing dump/restore to display
1257 garbage characters instead of the remote host name.
1258
1259 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1260 =====================================================================
1261
1262 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1263 <kukuk@suse.de> for submitting the patch.
1264
1265 2. Fix for the exit code when using the size estimate option of
1266 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1267 submitting the patch.
1268
1269 3. Handle EINTR in atomical reads/writes in dump, which was causing
1270 dump to fail on some systems. Thanks to Eric Jergensen
1271 <eric@dvns.com> for reporting the bug and submitting the patch.
1272
1273 4. Handle more than 16 characters for the device names in dumpdates.
1274 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1275 tracking down the problem and proposing the solution.
1276
1277 5. Fixed a bug in dump which prevented the creation of the
1278 dumpdates file when doing a 0-level dump without already
1279 having a dumpdates file. Thanks to Patrik Schindler
1280 <poc@pocnet.net> for reporting the bug.
1281
1282 6. Changed the way dump 'S' flag reports the size estimate
1283 from number of blocks into bytes (making it compatible
1284 with the Solaris version, and simplifying things for
1285 amanda users). Thanks to Jason L Tibbitts III
1286 <tibbs@math.uh.edu> for reporting the bug.
1287
1288 7. Fixed a compatibility problem in linux/alpha dump tape format.
1289 Now the linux/alpha dump are (again) compatible with the
1290 other dump formats. But this breaks compatibility with
1291 older dumps made on alpha. Thanks to Mike Tibor
1292 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1293
1294 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1295 ======================================================================
1296
1297 1. Added a '--enable-kerberos' to configure.
1298
1299 2. Added a 'S' option to dump which determines the amount of space
1300 that is needed to perform the dump without actually doing it, similar
1301 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1302 <cermak@ahab.rutgers.edu>.
1303
1304 3. Added a 'M' multi-volume option to dump and restore which enables
1305 dumping to multiple files (useful when dumping to an ext2
1306 partition to make several dump files in order to bypass the 2GB
1307 file size limitation). The 'f' argument is treated as a prefix and
1308 the output files will be named <prefix>001, <prefix>002 etc. With
1309 the 'M' flag, restore automatically selects the right file without
1310 asking to enter a new tape each time.
1311
1312 4. Fixed a memory leak which was causing dump to grow very big
1313 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1314 Fearon <jasonf@netrider.org.au> for reporting the bug.
1315
1316 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1317 ======================================================================
1318
1319 1. Make configure test if the system glob routines support
1320 extended syntax (ALTDIRFUNC). If not, use the internal glob
1321 routines instead of system ones. Thanks to Bernhard Sadlowski
1322 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1323 and helping me resolve this and other minor libc5 compiling
1324 glitches.
1325
1326 2. Fix a problem when dumping a ext2fs with the 'filetype'
1327 feature enabled. Thanks to Patrick J. LoPresti
1328 <patl@cag.lcs.mit.edu> for reporting the bug and to
1329 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1330
1331 3. Made the nodump flag work on directories. A directory which
1332 has the nodump flag gets never dumped, regardless of its
1333 contents.
1334
1335 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1336 which allows dump on an active ext3 filesystem. However, this
1337 is a "quick and dirty" patch which enables backup of an ext3
1338 filesystem through the ext2 compatibility (by ignoring the
1339 NEEDS_RECOVERY bit). The journal file is not recognized and
1340 it is dumped (it should not).
1341
1342 5. Test the superblock compatibility flags when dumping, in order
1343 to be sure that we know how to deal with specific features.
1344
1345 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1346 ====================================================================
1347
1348 1. Use lchown instead of chown, fixing a possible security problem
1349 when restoring symlinks (a malicious user could use this
1350 to deliberately corrupt the ownership of important system files).
1351 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1352 this and providing the patch.
1353
1354 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1355 ====================================================================
1356
1357 1. Put dump sources under CVS, added Id tags in all files so
1358 one can use 'ident' on binary files.
1359
1360 2. Added the dump/restore version in the usage text so one can
1361 easily verify the version he is using.
1362
1363 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1364 a va_start/va_end problem on linux-ppc (always call va_start
1365 va_end in pairs each time we use a vararg function).
1366
1367 4. Added again the DT_* constants because old libc does not
1368 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1369 for submitting the bug report.
1370
1371 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1372 this should enable dumping big (huge) filesystems.
1373
1374 6. Added the RSH environment variable in order to be able to
1375 use a rsh replacement like ssh when doing remote backups (and
1376 bypass the security limitations of rcmd). Now you can do remote
1377 backups without being root (or making dump setuid root).
1378
1379 7. Modified again the way dumpdates works. For incremental dumps,
1380 we need to read dumpdates even if we are not using 'u' option.
1381 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1382 this should work.
1383
1384 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1385 ===================================================================
1386
1387 1. Removed the 'k' flag from the restore 'about' text if kerberos
1388 was not compiled in.
1389
1390 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1391 to them (fsetflags takes a char*, setflags an open fd!).
1392
1393 3. (f)setflags is called only if the flags aren't empty. If the
1394 file is a special file, a warning is printed, because changing
1395 flags implies opening the device. Normally, a special file
1396 should not have any flag... (Debian bug #29775, patch provided
1397 by Abhijit Dasgupta <abhijit@ans.net>).
1398
1399 4. Made possible to dump a file system not mentioned in /etc/fstab.
1400 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1401
1402 5. Changed the default behaviour to not create dumpdates
1403 unless 'u' option is specified. Removed the old "debian-patch"
1404 which provided the same thing. (Debian bug #38136, #33818).
1405
1406 6. Removed all those dump*announce, since they were getting old...
1407
1408 7. Added warning messages if dumpdates does not exist and
1409 when an inferior level dump does not exist (except for a level 0
1410 dump).
1411
1412 8. Debugged the glob calls in interactive mode: restore used a
1413 dirent struct which was different from the /usr/include/dirent.h
1414 one (this used to work, is it a glibc2 change?), so none of the
1415 compat glob (which used /usr/include/dirent.h) or the system glob
1416 worked. Restore use now the system dirent (and the system
1417 DT_* constants), which are compatible with BSD ones.
1418
1419 9. Added a configure flag (--with-dumpdatespath) to specify
1420 the location of dumpdates file. By default, it is
1421 /etc/dumpdates.
1422
1423 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1424 included the current date/version in man pages.
1425
1426 11. Corrected the estimation of remaining time when
1427 the operator doesn't change the tapes quickly enough. This
1428 was an old bug, I thought I corrected it, and discovered
1429 that in fact it was corrected in two different places, so
1430 the results canceled each other...
1431
1432 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1433 ===================================================================
1434
1435 1. Integrated multiple patches from RedHat, Debian and SuSE:
1436
1437 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1438 isn't specified.
1439 - several fixes in the man pages.
1440 - update the default tape device to /dev/st0.
1441 - many updates for Linux Alpha (byte ordering, size_t etc).
1442 - buffer overruns.
1443 - use environment variable for TMPDIR (instead of /tmp).
1444 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1445 - workaround egcs bug (RedHat bugs #4281 and #2989).
1446 - wire $(OPT) throughout Makefile's.
1447
1448 2. Upgrade the dump revision to 1, making possible to dump filesystems
1449 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1450
1451 3. Fix some compile warnings, prototype all functions.
1452
1453 4. Use glibc err/glob instead of internal compatibility
1454 routines (only if available).
1455
1456 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1457 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1458
1459 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1460 ======================================================================
1461
1462 1. Integrated the changes from FreeBSD-3.1-RELEASE
1463 (mostly bug fixes, buffer overruns, dump has now an "automatic
1464 tape length calculation" flag, dump/restore can use kerberos now
1465 (this is NOT tested), use environment variables for TAPE and
1466 RMT etc.).
1467
1468 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1469
1470 3. Corrected a bug in restore when using 'C' option with multi-volumes
1471 tapes (files splited accros two tapes give "size changed" errors
1472 when comparing).
1473
1474 4. Corrected the long standing bug when dumping multiple tapes.
1475 This works for me, needs further testing.
1476
1477 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1478 ====================================================================
1479
1480 1. Dump now runs correctly on kernels 2.1.x
1481 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1482
1483 Changes between versions 0.4b2 and 0.4b3
1484 ========================================
1485
1486 1. Use realpath() if available
1487
1488 2. Report statistics
1489
1490 Changes between versions 0.4b1 and 0.4b2
1491 ========================================
1492
1493 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1494 the patch)
1495
1496 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1497
1498 3. Fixed configure.in to correctly handle --enable-rmt
1499
1500 Changes between versions 0.3 and 0.4b1
1501 ======================================
1502
1503 1. Integrated the changes from 4.4BSD-Lite2
1504
1505 2. Integrated the patches from Debian and Red Hat
1506
1507 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1508
1509 4. Changed dump to use the Ext2fs library to get block addresses. This
1510 should solve the endianness problem on SparcLinux.
1511
1512 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1513 distribution's one) to use autoconf
1514
1515 6. Fixed a few minor bugs
1516
1517 Changes between versions 0.2e and 0.2f
1518 ======================================
1519
1520 1. Added the creation of named pipes (fifos) in restore.
1521
1522 2. Added the -N flag in the restore manual page.
1523
1524 3. Added the file kernel.patch which contains the llseek() optimization
1525 patch for 1.2.x kernels.
1526
1527 4. Fixed a bug in the restoration of symbolic links: owner and group were
1528 not restored.
1529
1530 5. Integrated some changes from FreeBSD 2.2.
1531
1532 6. Added a call to ftruncate() after restoring each file to restore
1533 correctly files ending by a hole.
1534
1535 Changes between versions 0.2d and 0.2e
1536 ======================================
1537
1538 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1539 with owner = root (0) and group = root/wheel/whatever (0).
1540
1541 Changes between versions 0.2c and 0.2d
1542 ======================================
1543
1544 1. Dump is now able to backup 2GB+ filesystems.
1545
1546 2. Dump and restore can now be linked as static binaries.
1547
1548 Changes between versions 0.2b and 0.2c
1549 ======================================
1550
1551 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1552
1553 Changes between versions 0.2a and 0.2b
1554 ======================================
1555
1556 1. Really fixed the bug that I should have corrected in 0.2a.
1557
1558 2. Enabled optimization again.
1559
1560 Changes between versions 0.2 and 0.2a
1561 =====================================
1562
1563 1. Disabled the optimization during compilation.
1564
1565 Changes between versions 0.1 and 0.2
1566 ====================================
1567
1568 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1569 the fs_type field (actually, I modified the file fstab.c to make it
1570 use the mntent functions).
1571
1572 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1573 made by dump should be readable by the BSD restore and backups made
1574 by the BSD dump should be readable by restore. Unfortunately, this
1575 means that the dump format has changed between version 0.1 and version
1576 0.2 :-(
1577
1578 3. Dump is now able to backup a subtree, it is no longer limited to whole
1579 filesystems like the BSD version.
1580
1581 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1582 than 2 GB.
1583
1584 Changes between versions 0.0 and 0.1
1585 ====================================
1586
1587 1. Now create links rdump and rrestore during the `make install' step.
1588
1589 2. Linux port specific bugs added to the manual pages
1590
1591 3. Incorrect estimation of the number of tapes blocks fixed when doing
1592 incremental backups.
1593
1594 4. Better ls-like format in restore in interactive mode.
