3 Changes between versions 0.4b44 and 0.4b45 (released ?????????????)
4 ===================================================================
5
6 1. Improve data throughput when using compression in dump by
7 allowing multiple slaves to compress in parallel. Thanks
8 to Phillip Susi <psusi@cfl.rr.com> for the patch.
9
10 2. Add dump encryption support and reorganise the whole
11 compression/encryption code as plugins. Thanks to
12 Bear Giles <bgiles@coyotesong.com> for the patch.
13
14 3. Add sqlite index support and reorganize the QFA code
15 as plugins. Thanks to Bear Giles <bgiles@coyotesong.com> for
16 the patch.
17
18 Changes between versions 0.4b43 and 0.4b44 (released June 10, 2011)
19 ===================================================================
20
21 1. Recognize ext4 partitions in dump -w commands (Sourceforge
22 bug #3125587, RedHat bug #658890). Thanks to Jan Görig
23 <jgorig@users.sourceforge.net> for reporting the bug and
24 submitting the patch.
25
26 2. Fix an issue with multi volume backups, which breaks
27 restoring of files which are splitted on two or more
28 volumes and are starting on 2nd tape or later (RedHat
29 bug #507948).
30
31 3. Fix a bug in dump when dumping files with holes. This bug
32 was introduced in 0.4b42 while adding ext4 support.
33 (Sourceforge bug #3133762).
34
35 4. Fix a bug in restore -P where useless index files for compressed
36 dumps were created (Debian bug #583093). Thanks to
37 Mark Wooding <mdw@distorted.org.uk> for the patch.
38
39 5. Fix SYS_clone invocation on s390 architectures (Sourceforge
40 bug #3303235). Thanks to Adam Tkac <atkac@redhat.com> for
41 reporting the bug.
42
43 6. Fix static builds. Thanks to Peter Volkov <pva@gentoo.org>
44 for the patches.
45
46 7. Fix false negatives in configure zlib test. Thanks to
47 Bear Giles <bgiles@coyotesong.com> for the patch.
48
49 8. Add quick regression script from Bear Giles <bgiles@coyotesong.com>.
50
51 9. Fix a bug introduced in 0.4b43 causing restore to crash when
52 asking for a new volume when doing multi-volume restores. Thanks
53 to Patrik Schindler <poc@pocnet.net> for reporting the bug.
54
55 Changes between versions 0.4b42 and 0.4b43 (released June 11, 2010)
56 ===================================================================
57
58 1. Fix a bug in dump making impossible to handle large toc files
59 (> 2 GB). Thanks to X DUGi <xdugi@users.sourceforge.net> for
60 reporting the bug (Sourceforge bug #2820629)
61
62 2. Fix 'restore -x' in multi-volume mode, which caused files being
63 spanned on the first and second volumes to be incorrectly extracted.
64 Thanks to Adam Tkac <atkac@redhat.com> for reporting the bug.
65 (there may be several bug reports about this issue, including
66 Sourceforge bug #2117008, RedHat bugs #232415 and #444958).
67
68 3. Remove -lselinux -lsepol from the standard libraries list,
69 they shouldn't be needed if selinux is not enabled in dump
70 (this also fixes a build failure when selinux libraries are
71 not installed).
72
73 4. Fix restoration of extended attributes of fifos and device nodes.
74 Thanks to Igor Zhbanov <izh1979@gmail.com> for the bug report.
75
76 5. Don't attempt to set extended attributes on files that were not
77 extracted in 'restore -N' mode. Thanks to Jan Görig
78 <jgorig@users.sourceforge.net> for the patch.
79
80 6. Make the dump man page explicit about ext4 support.
81
82 7. Fix a bug in dump which caused EA entries to be unrecognizable by
83 restore in some corner cases. Add a workaround to restore making
84 it able to properly deal with those corrupted EA entries. Thanks
85 to John Austin <jaustin1@users.sourceforge.net> for reporting
86 the bug.
87
88 8. Fix some issues when restoring a dump which was generated using
89 exclusion patterns (either via -e or via the nodump attribute)
90 (see the Debian bug #574667 for details. Thanks to Frédéric
91 Brière <fbriere@fbriere.net> for the bug report and the associated
92 patch.
93
94 9. Fix progress/estimated blocks display in dump when doing really
95 huge backups. Thanks to Steve Bonds <sbonds@users.sourceforge.net>
96 for the bug report and tests. (Sourceforge bug #2987758)
97
98 10. Improve level 1 dump speed by rearanging the "mapdirs" code.
99 Thanks to Andreas Kies <andikies@t-online.de> for finding the
100 bottleneck and sending a patch (Sourceforge bug #2998119).
101
102 11. Use only ctime in order to compare newness instead of both
103 ctime and mtime. This should both speed up dumping time and
104 correct some side-effect bugs (like dumping files with an mtime
105 in the future in every incremental backup). Thanks to
106 Kieran Clancy <codebeard@users.sourceforge.net> for reporting the
107 bug (Sourceforge bug #2999207).
108
109 12. Extract dumped UNIX sockets instead of ignoring them.
110 (Sourceforge bug #3007216).
111
112 13. Compiler warning fixes (mainly warn_unused_result ones).
113
114 Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009)
115 ===================================================================
116
117 1. Fix printout of the 'Connection to' message in dump/restore.
118 Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
119 bug report and its fix.
120
121 2. Fix dump -w/-W output for filesystems having the last backup
122 level equal to 0. Thanks to Pascal Bouchareine
123 <kalou@users.sourceforge.net> for reporting the bug.
124
125 3. Enable restore to handle restoring onto a different SELinux
126 policy from the dump. Thanks to Tony Nelson
127 <tony_nelson@users.sourceforge.net> for the patch.
128 (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845
129 for details)
130
131 4. Fix EA set failures when restoring immutable files. Thanks
132 to Andrew Kroeger for the patch.
133
134 5. Fix "mode file too large" errors when restoring huge backups.
135 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
136 report.
137
138 6. Add the ability to link against libtinfo library if present,
139 instead of libtermcap or libncurses libraries. Thanks to
140 Adam Tkac <atkac@redhat.com> for the patch.
141
142 7. When comparing a backup, do not consider to be an error the fact
143 that we encounter files created while dump was in progress.
144 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
145 report.
146
147 8. Force '-a' to be the default value when running 'restore -C'.
148 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
149 report.
150
151 9. Many improvements to the 'cron_dump_to_disk' example.
152 Thanks to Aaron S. Hawley <ashawley@users.sourceforge.net> for
153 the patch.
154
155 10. Fix the QFA generation when extended attributes are backuped
156 along with the inodes. Prior to this fix, the entries for
157 some inodes may get corrupted (duplicated entries or incorrect
158 ones), making the QFA file unusable for repositionning in
159 restore. Many thanks to Kenneth Porter <shiva@sewingwitch.com>
160 for the bug report and the testing of the fix.
161
162 11. Fix EA restoration in debug mode (Sourceforge bug #1986216).
163
164 12. Stefan Auracher <star7@onlinehome.de> noticed that the Tower
165 of Hanoi backup strategy documented in the man page wasn't
166 actually based on the Tower of Hanoi algorithm. The man page
167 was updated accordingly.
168
169 13. Fix missing level information from dump output when using
170 the default level (RedHat bug #493635). Thanks to Adam Tkac
171 <atkac@redhat.com> for the patch.
172
173 14. Fix the dump man page to reflect the fact that the default
174 dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac
175 <atkac@redhat.com> for the patch.
176
177 15. Fixed a few spelling errors in the man pages (RedHat bug #489853).
178 Thanks to Adam Tkac <atkac@redhat.com> for the patch.
179
180 16. Fixed restore man page and program usage which incorrectly stated
181 that -P and -A were both allowed in the same invocation (RedHat
182 bug #490627). Thanks to Adam Tkac <atkac@redhat.com> for the patch.
183
184 17. Use sys_clone under Linux to share I/O contexts between dump
185 processes, thus drastically increasing the performance of dump
186 under CFQ (which is the default I/O scheduler used in a number of
187 distributions). Thanks to Jeff Moyer <jmoyer@redhat.com> for the
188 patch.
189
190 18. Add (preliminary) ext4 support - thanks to libext2fs which does
191 all the job for us. Thanks to Gertjan van Wingerde
192 <gwingerde@gmail.com> for the patch.
193
194 Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
195 =====================================================================
196
197 1. Fix restore of dumped Access Control Lists. The previous
198 code for EA works fine, but ACLs needed conversion from the
199 ext2/3 disk format to posix_acl format before restoring.
200
201 2. Fix some issues with restoration of EA on big endian
202 platforms.
203
204 3. Fix restore when the symtab is over 2GB in size.
205
206 4. Made the directory hash indexing an optional feature,
207 accessible by the '-H' option of restore, and disable it
208 by default.
209
210 5. Fixed dump to not include extended attributes information
211 in the toc (archive) file which confused restore -t.
212
213 Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
214 =================================================================
215
216 1. Changed restore to emit warnings (instead of emitting a fatal
217 error) if a file (or a directory) is unavailable for a
218 comparision (if the user doesn't have the necessary permissions
219 to access it for example). Thanks to Kenneth Porter
220 <shiva@sewingwitch.com> for the bug report.
221
222 2. Re-done the 'do not save directory entries to non-dumped inodes
223 (excluded from dump)' feature. The previous implementation
224 worked well for excluded directories but not for regular files.
225 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
226 report.
227
228 3. Fixed a bug in dump where the tape size was miscalculated when
229 the user used -d/-s to specify the tape characteristics. Thanks
230 to Philip Goisman <goisman@physics.arizona.edu> for reporting
231 the bug.
232
233 4. Fixed another bug introduced in restore with the hashtree
234 implementation. This one caused restore to stop saying
235 "removenode: non-empty directory" in some cases.
236
237 5. Added support for dumping and restoring ext2/3 extended
238 attributes (EA), like the access control lists (ACL) or
239 the security labels used by SELinux.
240
241 Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
242 ======================================================================
243
244 1. The newly added dump_on_cd_3 example was buggy, replace it
245 with an updated version from Andrew Basterfield
246 <bob@cemetery.homeunix.org>.
247
248 2. Made restore to chdir() back into the initial directory when
249 dumping core while aborting a comparision operation. The
250 previous behaviour was to write the corefile at the root of
251 the directory being compared, which could very well be
252 read only and preventing the corefile generation. Thanks
253 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
254
255 3. Silenced the failure to call fgetflags() when comparing an
256 entry which has no ext2 attributes (as in lsattr()).
257
258 4. Fix a brown paper bug in restore -C which broke restore and
259 caused modifications on the filesystem being compared
260 (directories containing a file with the same name as the
261 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
262 <shiva@sewingwitch.com> for finding the bug and helping me
263 reproduce it.
264
265 5. Made restore -C force the -N flag (no writing allowed on
266 the disk) in order to prevent more bugs like the above one.
267
268 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
269 =====================================================================
270
271 1. Fix a couple of troff syntax bugs in the man pages.
272 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
273
274 2. Made restore use either libncurses or libtermcap, depending
275 on which one is available at configure time.
276
277 3. Fixed restore negative size display bug when comparing a
278 dump containing files over 2GB. Thanks to Steve Bonds
279 <sbonds@users.sourceforge.net> for the bug report.
280
281 4. Do not save directory entries to non-dumped inodes
282 (excluded from dump). This will eliminate the 'missing
283 file' warnings when doing 'restore -C'.
284
285 5. Fix dump crash when backuping a huge (2TB) filesystem,
286 due to a bogus calculation on the inode map size.
287 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
288 submitting the bug and testing the fix.
289
290 6. Fix a problem in restore where the final \0 in the symbolic
291 link names could have been lost, generating corrupt filenames.
292 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
293 bug.
294
295 7. Implemented a hash list for the directory names in restore.
296 The linear list used before caused problems in interactive
297 restores when dealing with directories having thousands of
298 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
299 for reporting the bug.
300
301 8. Improved restore -C, this time including the directory
302 attributes into the comparision.
303
304 9. Made restore understand tapes containing EA/ACLs (which will
305 be dumped by the next version of dump). In this version
306 extended attributes on the tape are ignored, for full EA/ACL
307 support wait for the next version or try the experimental EA
308 patch.
309
310 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
311 ==================================================================
312
313 1. Added the --enable-staticz configure option which enables
314 dump and restore to be linked with static versions of
315 libz and libbz2 (and dynamic versions of all other libraries).
316 This will make Debian users happy, because libz and libbz2
317 were the only needed libraries living in /usr, all the
318 others live in /lib. In case of system emergency, it is
319 better not to have to rely on an extra filesystem.
320 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
321
322 2. Fix compilation on (at least the Linux Debian port to) AMD64.
323 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
324 that are also defined by <linux/types.h> (<asm/types.h>) and
325 they conflict).
326
327 3. Make dump's reading of the dumpdates file a bit more robust,
328 preventing dump from crashing when the dumpdates file has
329 been modified by hand.
330
331 4. Fixed some offset calculations in dump code which could
332 lead to "bread lseek errors" on large filesystems. Thanks
333 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
334 reporting this bug and debugging the issue.
335
336 5. Made dump use the blkid library when searching for devices
337 by label or uuid instead of dump's own routines.
338
339 6. Corrected a bug in dump where a wrong LABEL=... line in
340 /etc/fstab could prevent dump from dumping unrelated
341 filesystems. Thanks to Bruce Lowekamp
342 <lowekamp@users.sourceforge.net> for reporting the bug.
343
344 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
345 ====================================================================
346
347 1. Fixed dump compilation with old gcc versions. Thanks to
348 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
349
350 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
351 when compiling against a recent glibc version.
352
353 3. Fixed a bug in restore preventing the read of a dump tape
354 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
355 <phiggins@transzap.com> for reporting the bug and providing
356 the test case.
357
358 4. Changed dump to enable the creation of volumes of different
359 sizes in a single run (make -B accept a list of values).
360 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
361
362 5. Use the glibc provided minor() and major() macros instead
363 of our own bitmask implementation. This should be safe for
364 when the major/minor namespace will migrate to 32 bits.
365 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
366 the bug.
367
368 6. Made explicit in the dump man page that dump will not create
369 a remote file, it will only write to an already existing one.
370
371 7. Another try at making size estimates better again.
372
373 8. Put back the inconditional running of the end-of-tape
374 script which was changed in 0.434 to be run only when -M
375 or multiple -f were NOT specified. Some users rely on this
376 feature even when it is combined with -M/-f.
377
378 9. Fixed restore when restoring huge backups (where rstdir...
379 temporary files are over 2GB). Thanks to
380 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
381 debugging the issue and making the patch.
382
383 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
384 David <vrtin@users.sourceforge.net> for submitting the bug
385 and providing a test case.
386
387 11. Made dump work with an arbitrary integer level (no more 10
388 levels only limitation). Thanks to Matthew
389 <msvincen@midway.uchicago.edu> for the patch.
390
391 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
392 =======================================================================
393
394 1. Added a note in the dump man page saying that the default
395 blocksize can be 32 if -d is used with a high density argument.
396 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
397 for the patch.
398
399 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
400 LDFLAGS environment variables. Thanks to Arcady Genkin
401 <antipode@users.sourceforge.net> for reporting the bug.
402
403 3. Made -e/-E options of dump accept an unlimited number of inodes
404 to be excluded, rather than a hardcoded maximum. Thanks to
405 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
406
407 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
408 and -D_USE_BSD_SIGNAL defines in configure in order to solve
409 64bit build problems because quad_t is redifined with a
410 different signature. Thanks to Mike Harris <mharris@redhat.com>
411 for reporting this bug.
412
413 5. Made restore build on Solaris, making possible to
414 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
415 <uwe@ugsoft.de> for the patch.
416
417 6. Made an extension in the dump tape format capable of saving
418 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
419 wrote the extension and contributed the restore code back
420 into this codebase. The same extension mechanism will be
421 used in the future to save ACLs...
422
423 7. Made rmt work correctly with regard to QFA and local/remote
424 files and tapes. The remote access will however work only
425 when the dump provided rmt version is used. If you want to
426 use another rmt server, please do not use the QFA feature.
427 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
428
429 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
430 ====================================================================
431
432 1. Fixed the INSTALL file to reflect the actual install paths.
433 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
434 reporting the bug.
435
436 2. Fixed the configure script to only check for headers presence
437 instead of trying to compile them. This should fix issues
438 with old build environments. Thanks to Kari Lempiainen
439 <kari@funky.pp.fi> for reporting the bug.
440
441 3. Fixed restore to correctly ignore sockets when comparing
442 a dump (as socket cannot be properly restored anyway). Thanks
443 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
444
445 4. Fixed restore to correctly access the archive file (-A argument)
446 even when using a remote tape. Thanks to Fabrice Bellet
447 <fabrice@bellet.info> for reporting the bug.
448
449 5. Fixed (again) handling of long (largefile) seeks in rmt.
450 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
451 the bug.
452
453 6. Fixed restore corner case when dealing with large block sizes
454 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
455 <fabrice@bellet.info> for reporting the bug.
456
457 7. Fixed a bug preventing dump to access a filesystem having
458 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
459 for reporting the bug.
460
461 8. Made dump store dump dates using explicit timezones, fixing a
462 problem with incremental dumps if the timezone is modified
463 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
464 the bug report and the patch.
465
466 9. Fixed a bug encountered when dumping individual files (not full
467 filesystems or directories) and dangling symbolic links happen
468 to be in the list of files. For as far as dump is concerned,
469 dangling symbolic links are allowed, and are dumped as is.
470 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
471 bug and providing the fix.
472
473 10. Fixed open and creation modes and permissions for QFA and
474 table-of-contents files in dump and restore. Thanks to
475 Philippe Troin <phil@fifi.org> for the patch.
476
477 11. Fixed the archive file descriptor handling enabling it to be 0.
478 This can happen in some cases when shell redirections are used.
479 Thanks to Philippe Troin <phil@fifi.org> for the patch.
480
481 12. Delayed the opening of archive file until after suid had been
482 dropped (fixing a possible security issue if dump is suid).
483 Thanks to Philippe Troin <phil@fifi.org> for the patch.
484
485 13. Fixed the 'S' command handling in the rmt client part.
486 Thanks to Philippe Troin <phil@fifi.org> for the patch.
487
488 14. Modified the end-of-tape script handling to print out statistics
489 (and stop the timer) before launching the eot script. Also, the eot
490 script does not get run anymore when using -M (which makes sense) or
491 when multiple tapes are listed on the command line
492 (-f tape0,tape1,tapen) (which also makes sense).
493 Thanks to Philippe Troin <phil@fifi.org> for the patch.
494
495 15. Relicensed dump/restore under the 'revised' BSD license, as per
496 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
497
498 16. Added LZO compression to dump. This new compression method has
499 the advantage of being super fast, thus not killing tape streaming
500 on slow machines. Thanks to Helmut Jarausch
501 <jarausch@igpm.rwth-aachen.de> for the patch and to
502 Markus Oberhumer <markus@oberhumer.com> for giving special permission
503 to include his miniLZO project (GPL licensed) in dump/restore.
504
505 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
506 <ant@notatla.demon.co.uk> for reporting the bugs.
507
508 18. Added a special rmt version which can do encryption when writing
509 to tape. Read examples/encrypted_rmt/README for details on
510 how to enable and configure it. Thanks to Ken Lalonde
511 <ken@globalremit.com> for the patch.
512
513 19. Made dump work with 2.5 kernel end of tape early warning semantics.
514 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
515
516 20. Fixed a bug which caused dump -w|-W not to work anymore, because
517 the fs_freq and fs_passno fields in /etc/mtab are always set
518 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
519 reporting the bug.
520
521 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
522 =======================================================================
523
524 1. Added a note in the restore man page clarifying the question
525 'set the permissions on the current directory ?' asked by
526 restore at the end of treatment in -i and -x modes.
527
528 2. Fixed the endianess issues when reading compressed tapes.
529 Thanks to Dark Force <daq4th@users.sourceforge.net> for
530 reporting this bug and providing test cases.
531
532 3. Fixed the "ACL won't be dumped" warning message (which showed
533 an extra, unrelated error message). Thanks to Dragan Krnic
534 <dkrnic@lycos.com> for reporting this bug.
535
536 4. Made dump look first into /etc/mtab, then into /etc/fstab
537 when searching for filesystem paths. Also fixed some problems
538 caused by binding mounts or multiple block device mounts.
539 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
540 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
541 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
542 and #160305, Sourceforge bugs #618699 and #679832).
543
544 5. Made dump's -I option accept the value '0' meaning all the
545 read errors will be ignored. This can be useful when running
546 dump from unattended sessions (like cron jobs). Thanks to
547 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
548
549 6. Fixed the output of dump to indicate 'blocks' instead of
550 'tape blocks' in the various messages (blocks are always
551 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
552 made it clearly print the current blocksize at the start of
553 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
554 the suggestions.
555
556 7. Made rmt understand long (largefiles) seeks.
557
558 8. Fixed build with very old versions of libext2fs, where
559 EXT2_FT_* constants were undefined.
560
561 9. Made dump accept the dumpdates path on the command line
562 (-D file option) instead of using only the hardcoded one.
563 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
564 suggestion.
565
566 10. Enabled rmt, LFS, readline, QFA options by default in
567 ./configure. Updated the configure process (new versions
568 of config.guess, config.sub etc).
569
570 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
571 =======================================================================
572
573 1. Changed dump to use fcntl(F_SETLK) style locking instead
574 of flock() when locking the dumpdates file. With the old
575 locking scheme, a local user having read rights on the
576 dumpdates file could be able to do a Denial of Service attack
577 on dump. In order to lock the dumpdates file with the new
578 scheme, the user would need to have write access on the file.
579 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
580 reporting the bug (originally a bugtraq post).
581
582 2. Fixed interactive 'ls' which caused spurious errors warnings
583 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
584 <jorgen_ostling@users.sourceforge.net> for reporting this
585 bug.
586
587 3. Fixed dump's estimate when dealing with sparse inodes.
588
589 4. Modified dump to allow setting a blocksize bigger than 32kB
590 (raised the limit to 1024kB), because newer hardware needs
591 this for proper operation. Thanks to Dirk Traenapp
592 <dtraenapp@users.sourceforge.net> for reporting this.
593
594 5. Fixed a bug causing Dump to stop and report an error if an
595 inode number in the exclude file was followed by some amount
596 of whitespace. Thanks to Jeffrey Sofferin
597 <sofferin@users.sourceforge.net> for reporting this bug.
598
599 6. Fixed a bug which caused restore, in some particular cases,
600 to ask some 'scary' questions and leave a bunch of RSTTMP
601 directories behind when restoring incremental tapes. Thanks
602 to Philippe Troin <phil@fifi.org> for reporting this bug and
603 providing the test cases.
604
605 7. Changed the wording when inodes are excluded from dump:
606 replaced 'Added inode 7 to exclude list' with
607 'Excluding inode 7 (resize inode) from dump', as suggested
608 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
609
610 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
611 ===================================================================
612
613 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
614 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
615 <eros@lamel.bo.cnr.it> for reporting the bug.
616
617 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
618 ===================================================================
619
620 1. Made dump print out the ext2 logical block number in case of a read
621 error, which can be given as an argument to debugfs' ncheck command,
622 in order to find out the affected inode. Added note about this
623 usage in dump's man page.
624
625 2. Fixed a problem in restore when reading tapes written on big
626 endian machines with very old versions of dump. The patch was
627 contributed by George Helffrich <george@geology.bristol.ac.uk>.
628
629 3. Fixed the tape length calculation when using large tapes
630 and compression. Thanks to Georg Lippold
631 <g_lippold@sourceforge.net> for reporting the bug.
632
633 4. Added a new set of examples in dump_on_cd_2 directory, based
634 on dump_on_cd examples but somewhat enhanced, supporting DVD
635 media, and localized in english and german. Thanks to
636 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
637
638 5. Made dump save 32 bit UID/GID. Internally, this was achieved
639 by switching from the old BSD inode format to the new BSD
640 inode format, which means that the tape format was changed.
641 However, since all restore versions out there should
642 transparently support both inode formats, the change should
643 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
644 reporting the bug.
645
646 6. Fixed a lot of warnings in the code shown when compiling
647 with 'gcc -W'. Thanks to Matthias Andree
648 <matthias.andree@stud.uni-dortmund.de> for reporting this.
649
650 7. Fixed a small markup bug in the dump man page. Thanks to
651 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
652 patch.
653
654 8. Rewrote entirely the man pages using the tmac.an macro
655 package (Linux man page format) instead of the original BSD
656 format. They should be now cleaner and easier to modify.
657
658 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
659 ==================================================================
660
661 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
662 non Linux clients were misinterpreted. The description of the problem
663 (incompatible numbering in Linux mtio opcodes) is documented at
664 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
665 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
666 providing an excellent, cross-platform replacement for rmt in his
667 star package.
668
669 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
670 which caused restore to fail when the inode maps were not entirely
671 contained on the first volume (when using really small volumes or
672 when dumping a huge number of inodes).
673
674 3. Fixed a problem in dump, where files in subdirectories of directories
675 that have the nodump flag set (or being excluded with -e/-E) were
676 sometimes incorrectly dumped (instead of being excluded). The original
677 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
678 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
679 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
680 help testing the patch.
681
682 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
683 which makes one able to pipe the output of dump, by the net, to
684 a remote CD-burner server.
685
686 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
687 and use GNU's symbolic syntax over rmt instead of numerical values
688 to assure multiple platform compatibility.
689
690 6. Documented the -d option in restore.
691
692 7. Added a -v (verbose) mode to dump. For now it just prints the number
693 of the inode being dumped, but this could evolve in future versions
694 to include interesting debugging output.
695
696 8. Added a -o flag to restore, which automatically restores the current
697 directory permissions in -i or -x mode, without asking the operator
698 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
699 and Peter Samuel <peters@e-smith.com>.
700
701 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
702 ====================================================================
703
704 1. Fixed a bug in the QFA feature which could have caused
705 a bad tape positionning on restore (causing extra delays in
706 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
707
708 2. Added a small note in the dump man page specifying that
709 there should be no white space between the option letter and
710 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
711
712 3. Made restore work with older versions of the readline library,
713 by checking in configure for several extended symbols. Restore
714 can now be compiled with a readline as old as the 2.0 release
715 (though it may be a good idea to upgrade it to a more recent
716 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
717 reporting the build failures.
718
719 4. Fixed a performance problem with the QFA file creation in
720 dump, which made unnecessary seeks on the tape slowing down
721 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
722 reporting this issue.
723
724 5. Removed the inclusion of some kernel headers in the dump
725 source, which prevented the compile in some kernel/glibc
726 headers/architecture combination. Thanks to Bdale Garbee
727 <bdale@gag.com> for reporting the bug.
728
729 6. Added the appropriate error message when dump fails to
730 open the output file for writing. Thanks to Amith Varghese
731 <amithv@yahoo.com> for reporting this bug.
732
733 7. Made restore able to understand large Solaris ufsdump tapes
734 (containing inodes bigger than 4194304). Sun have introduced
735 an "extension" to the dump tape format when dealing with
736 those inodes, which was uncorrectly handled by Linux restore.
737 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
738 providing a test case.
739
740 8. Added the -m parameter to dump which optimises the output for
741 inodes having been changed but not modified since the last dump
742 ('changed' and 'modified' have the meaning defined in stat(2)).
743 For those inodes, dump will save only the metadata, instead of
744 saving the entire inode contents. Inodes which are either
745 directories or have been modified since the last dump are saved
746 in a regular way. Uses of this flag must be consistent, meaning
747 that either every dump in an incremental dump set have the flag,
748 or no one has it.
749
750 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
751 =======================================================================
752
753 1. Fixed behaviour of dump when exceeding resource limits
754 (SIGXFSZ treatment).
755
756 2. Added the -L flag to restore to allow the user to specify a
757 maximal allowed number of miscompares when using restore
758 with the -C option to check the backup.
759
760 3. Detailed the manual entry for the -N option of restore.
761
762 4. Added the -a flag to restore to make able doing unattended
763 restores in -i or -x mode (automatically walks through the
764 multiple dump volumes).
765
766 5. Extended the QFA mode to work with local files and/or
767 remote tapes and files. This way, restore can know in advance
768 the tape number and the offset for the inodes to extract and
769 can minimize the extraction time by seeking directly to the
770 good tape/offset.
771
772 6. Added the -A <archive> option to both dump and restore,
773 which makes dump to archive a dump table-of-contents in
774 the specified file to be used by restore to determine
775 whether a file is in the dump file that is being restored.
776 (the archive file syntax is also compatible with the
777 Solaris ufsdump generated one).
778
779 7. Small fix in restore making it able to read some (broken ?)
780 Solaris ufsdump tapes.
781
782 8. Fixed dump to correctly recognise the root filesystem when using
783 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
784 for reporting this bug.
785
786 9. Added the -P <file> option to restore to create a
787 Quick File Access file from an already made dump. Patch
788 contributed by Uwe Gohlke <uwe@ugsoft.de>.
789
790 10. Made restore compile and run on Solaris, making it a
791 possible replacement for the standard ufsrestore. Port was
792 contributed by Uwe Gohlke <uwe@ugsoft.de>.
793
794 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
795 =====================================================================
796
797 1. Added a set of backup scripts from Eugenio Diaz
798 <getnito@yahoo.com> in the examples section. It features
799 automatic (cron based) full and incremental dumping of
800 several filesystems on a separate filesystem.
801
802 2. Fixed a off-by-one miscalculation which disabled dumping
803 a one letter subdirectory. Thanks to Chris Siebenmann
804 <cks@utcc.utoronto.ca> for reporting the bug.
805
806 3. Fixed several restore bugs occuring when trying to
807 restore some missing files on the tape. Thanks to Chris
808 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
809
810 4. Fixed --with-ldopts configure argument passing, installing from
811 a separate object directory, makefile cleanups contributed
812 by <splite@purdue.edu>.
813
814 5. Fix a bug which could caused, in some conditions, the highest
815 number inode of a filesystem, to not be dumped. Many thanks
816 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
817 chase this bug.
818
819 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
820 =======================================================================
821
822 1. Added a mini howto from Patrick Walsh in the examples
823 directory.
824
825 2. Minor man pages syntax corrections. Thanks to
826 Chris Danis <screechco@home.com> for reporting the bugs.
827
828 3. Added a script from David B. Peterson <dave@toppledwagon.com>
829 to the examples section. It features dumping several
830 filesystems to a remote tape drive upon ssh.
831
832 4. Added a patch provided by Richard Jones <rich@annexia.org>
833 which allows BRADEMAX (number of read errors tolerated by
834 dump) to be adjusted using the -I option.
835
836 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
837 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
838 patch.
839
840 6. Add the -l option to restore to specify if, when doing a
841 remote restore, the file used to access the backup is a
842 regular file (the defaults being a tape drive). Restore needs
843 to know this information when reading a remote compressed
844 dump. Previously, this information was autodetected, but
845 the autodetection code fails (with ioctl: Inappropriate ioctl
846 for device) when using a non Linux remote box. Thanks to
847 many users and especially to Eros Albertazzi
848 <eros@lamel.bo.cnr.it> for reporting this.
849
850 7. Found a workaroung for the dump deadlock problem (3 childs
851 stuck in pause(), father in read()). The workaround seems
852 to work for me and several beta-testers. If it doesn't work
853 for you, please report back.
854
855 8. Updated the RPM spec file (BuildPrereq, URL etc).
856
857 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
858 ========================================================================
859
860 1. Fixed the permissions of a newly created QFA file by dump.
861
862 2. Cleaned up the source of dump (the external variables
863 definition was a complete mess, making possible to have
864 objects overlap).
865
866 3. Fixed restore to use the full tape volume path when doing
867 a compare (since it changes the working directory to the
868 filesystem being compared in the process).
869
870 4. Added the -q option to dump which makes dump abort
871 whenever it needs operator attention. It should be
872 easier to use dump in scripts with this option.
873
874 5. Detect the use of incompatible options to dump and
875 refuse them (like -a and -B options together).
876
877 6. Added bzip2 compression to dump/restore (use option -j level
878 to select it). Note that you will need a restore version
879 >= 0.4b24 in order to restore a bzip2 compressed dump.
880 The same warning as for the zlib compression applies:
881 the tape format of a bzip2 dump is not compatible with the
882 original BSD tape format.
883
884 7. Fixed a overflow problem in dump corrupting the dump when
885 very large files were encountered. Thanks to Vladimir Nadvornik
886 for the bug report.
887
888 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
889 kernel buffer/page cache before starting the dump, helping
890 a bit those who use dump on mounted filesystems. Thanks to
891 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
892 for this suggestion.
893
894 9. Updated the RPM spec file following the RedHat changes
895 (dynamically linked binaries now in /usr/sbin etc).
896
897 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
898 which enables restore to recognise multi volume compressed dumps
899 done on CD. Included his scripts for dump (which pipe the dump
900 output directly into cdrecord) and restore. There is now
901 possible to to backups to CD on the fly!
902
903 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
904 ===================================================================
905
906 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
907 Marcus Meissner (Caldera International Security Dept.).
908
909 2. Implement the Sun rmt extended protocol. Patch submitted
910 by Ian Gordon <iangordon@users.sourceforge.net>.
911
912 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
913 the linux kernel header. This ensures that dump always has the
914 latest version of this file. Patch submitted by
915 Andreas Dilger <adilger@turbolinux.com>.
916
917 4. Report any filesystem present in either /etc/fstab with a
918 positive passno or /etc/dumpdates in dump -w output.
919 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
920
921 5. Fixed the looping problem in dump introduced in the
922 previous version.
923
924 6. Changed the -B option of dump to limit the size of
925 _compressed_ output per volume if compression is on.
926 Patch contributed by Helmut Jarausch
927 <jarausch@igpm.rwth-aachen.de>. Note however that, since
928 it is impossible to predict the size of the compressed
929 data before doing the compression, the -B limit is a bit
930 conservative.
931
932 7. Fixed a bug in reading the operator typed file/tape path for
933 the next volume in restore.
934
935 8. Implemented a "-F script" option to restore which permits the
936 user to specify a script which will be launched at the
937 beginning of each tape, useful for automatic programming of
938 tape changers for example. See the restore man page for the
939 script parameters and return codes.
940
941 9. Small fix for the QFA routines provided by Uwe Gohlke
942 <uwe@ugsoft.de>, and some recommendations for QFA uses in
943 the man pages.
944
945 10. Fixed the multivolume restoring where making a mistake
946 to the 'Mount next tape' prompt caused several blocks to
947 be lost.
948
949 11. Enhanced the -e option of dump to take as a parameter a
950 comma separated list of inode numbers.
951
952 12. Added the -E option to dump which specify a file containing
953 inode numbers to exclude from the dump.
954
955 13. Fixed the compressed multi-volume dump + restore.
956
957 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
958 ==================================================================
959
960 1. Made dump report the number of blocks dumped per volume.
961 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
962
963 2. Fix a bug in dump where waiting too much at the 'change volumes'
964 question caused the volume to be rewritten. Thanks to
965 Graham Reed <greed@users.sourceforge.net> for reporting the
966 bug and providing a patch.
967
968 3. Added a compression option to dump, contributed by Jerry
969 Peters <gapeters@worldnet.att.net>.
970
971 WARNING: the compression works only on files/pipes and
972 drives supporting variable block size.
973
974 WARNING2: tapes created using the compression feature are
975 incompatible with the standard dump tape format, and a
976 version of restore >= 0.4b22 will be needed for extraction.
977
978 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
979 architectures. Thanks to Paul Slootman <paul@debian.org> for
980 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
981 it upstream.
982
983 5. Many cleanups (CPP defines, const char warnings, check of
984 ext2fs COMPAT flags, time_t cleanups, added libext2 version
985 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
986
987 6. Made --prefix option work in configure. All the install path
988 are now based on the configure parameters.
989
990 7. Added the Quick File Access mode in dump/restore, contributed
991 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
992 a file tape position for each inode, and this file is used by
993 restore (if called with parameter Q and the filename)
994 to directly position the tape at the file restore is currently
995 working on. This saves hours when restoring single files from
996 large backups, saves the tapes and the drive's head. Use
997 --enable-qfa option of configure to compile in the QFA support.
998
999 8. Added the possibility to dump several files and directories
1000 in a single invocation of dump. Thanks to Uwe Gohlke
1001 <uwe@ugsoft.de> for implementing this option.
1002
1003 9. Fixed the dumping and restoring of files with holes
1004 (files ending with holes didn't get dumped or restored
1005 correctly).
1006
1007 10. Fixed a socket descriptor leak in dump, which leaved opened
1008 3 file descriptors per dump process (and there is one dump
1009 process per tape).
1010
1011 11. Fixed dump large file system support, by explicit use of
1012 open64/lseek64/etc functions (explicit use needed because
1013 e2fsprogs libraries don't behave well when compiled with
1014 FILE_OFFSET_BITS=64).
1015
1016 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
1017 ======================================================================
1018
1019 1. Fixed some bugs in the dump -w|-W logic introduced by
1020 the previous version. Thanks to Andreas Dilger
1021 <adilger@turbolinux.com> for his help on this one.
1022
1023 2. Fixed again a compilation problem when using old e2fs
1024 headers (filesystem label related). Thanks to many users
1025 who reported this stupid error.
1026
1027 3. Fixed a build problem on old lib5 based systems dealing with
1028 _PATH_MNTTAB being undefined. Thanks to John Adams
1029 <johna@onevista.com> for reporting the bug.
1030
1031 4. Improved the error detection in restore when creating
1032 the temporary files in TMPDIR. Now restore will corectly
1033 report a 'no space left on device' error instead of
1034 strange errors which could imply an archive corruption.
1035 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
1036 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
1037
1038 5. Added the throughput information in dump's progression
1039 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
1040 for the patch.
1041
1042 6. Use libext2fs's inode scanning routines, which are particularly
1043 robust when dealing with errors (especially when having some
1044 bad blocks on the filesystem). Many thanks to Colin
1045 <colin@horizon.com> for reporting the bug, investigating
1046 the issues, finding a workaround, writing the patch and
1047 fully testing it... (of course, if this patch will break
1048 anything, he is to blame for :-)).
1049
1050 7. Made dump and restore LFS aware. Dump can dump a filesystem
1051 containing large files, generate a large file on output and
1052 restore can restore them. This feature is not enabled by
1053 default, use --enable-largefile option of configure to enable
1054 it (you need to have a LFS aware glibc though). Thanks to
1055 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
1056 and to Theodore T'so <tytso@valinux.com> for his always
1057 useful thoughts.
1058
1059 8. Made dump ask upon a tape write error if it should rewrite
1060 the current volume (assume this is a bad tape) or if it should
1061 assume an end-of-tape condition (useful for tape drives which
1062 behaves badly at the end of the tape). Thanks to Andreas
1063 Dilger <adilger@turbolinux.com> for the suggestion.
1064
1065 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
1066 =======================================================================
1067
1068 1. Fixed a small compilation problem due to a change
1069 in the definintion of the struct sigaction in
1070 glibc 2.0 / libc5. Thanks to Gunther Schlegel
1071 <schlegel@riege.de> for reporting the bug and to
1072 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
1073 a fix.
1074
1075 2. Modified the label and uuid analysis in order to be
1076 self-contained (independant of kernel/libc headers). This
1077 should fix the compile with older kernel/libc headers and
1078 will preserve the functionality. Thanks to Bernhard Erdmann
1079 <bernhard.erdmann@gmx.de> for reporting the bug.
1080
1081 3. The 'exclude inode' option, if applied to a directory
1082 inode, excludes now correctly all the leaves of this
1083 directory. Thanks to John R. Dennison
1084 <gerdesas@users.sourceforge.net> for reporting the bug.
1085
1086 4. Fixed the '-e' option to disable the possibility
1087 to exclude the root inode (which causes the dumps to
1088 be unreadable by restore). Prevented array overflow
1089 when multiple -e options are used.
1090
1091 5. Fixed dump to correctly interpret a filesystem argument
1092 which is a mountpoint and it is not an absolute path
1093 (as specified in the fstab). Thanks to Bernhard R. Erdmann
1094 <be@berdmann.de> for reporting the bug.
1095
1096 6. Made dump able to backup files larger than 2 GB. Note that
1097 dump still doesn't cope with files larger than 4 GB.
1098
1099 7. Restore the real uid and gid before invoking an external
1100 RSH program (big hole when dump or restore is suid root!).
1101
1102 8. Get the values for the default tape device and the location
1103 of fstab file from the system headers. Thanks to
1104 Andreas Dilger <adilger@turbolinux.com> for the patch.
1105
1106 9. Made dump -w|-W report all recognized filesystems
1107 present in either /etc/fstab or /etc/dumpdates, and present
1108 the list in the same order as in fstab file. Thanks
1109 to Andreas Dilger <adilger@turbolinux.com> for the patch.
1110
1111 10. Made dump's -a (automatic end of tape detection) the
1112 default. Specifying one of -B, -c, -d or -s options will
1113 override the EOM detection. Thanks to Andreas Dilger
1114 <adilger@turbolinux.com> for the patch.
1115
1116 11. Save the ext2 filesystem label into the dump volume label.
1117 Specifying a volume label on the command line (-L option)
1118 will override this feature. Thanks to Andreas Dilger
1119 <adilger@turbolinux.com> for the patch.
1120
1121 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
1122 =====================================================================
1123
1124 1. Fixed the signal handling in dump (which I broke in 0.4b17)
1125 which was causing several strange dump failures (dump
1126 hanged or segmentation faults etc).
1127
1128 2. Specified the default blocksize in the dump man page.
1129
1130 3. Changed two info messages of restore to be written on stdout
1131 instead of stderr in order to leave stderr only for errors
1132 or warnings. Thanks to Stephen Atwell
1133 <satwell@urbana.css.mot.com> for the suggestion.
1134
1135 4. Corrected an off by one calculation which prevented
1136 dumping a directory having a 1 character name length.
1137 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
1138 for reporting the bug.
1139
1140 5. Reinforce dump in order to allow only level 0 and no
1141 -u option when dumping a subdirectory, and document
1142 this in the man page. Thanks to Bernhard Erdmann
1143 <bernhard.erdmann@gmx.de> for reporting the bug.
1144
1145 6. Fixed a small harmless bug in restore which caused
1146 in some conditions hard links to be restored several
1147 times (therefore generation some warning messages).
1148 Thanks to Kenneth Porter <shiva@well.com> for
1149 reporting the bug.
1150
1151 7. Updated the RPM spec file to the latest RedHat version,
1152 providing FHS packaging and other cosmetic changes.
1153 You will need RPM version >= 3.0.5 in order to build the RPM.
1154
1155 8. Updated the configure script to check for libtermcap
1156 before checking for libreadline, because we need this
1157 library in order to compile the readline support.
1158
1159 9. Made dump understand the LABEL= and UUID= notation
1160 both in /etc/fstab and on the command line. Note that
1161 you will need the /proc filesystem in order to use
1162 these notations. Thanks to Erik Troan <ewt@redhat.com>
1163 for providing the patch.
1164
1165 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
1166 ===================================================================
1167
1168 1. Fixed a potential buffer overflow in restore. Thanks
1169 to Stan Bubrouski <satan@fastdial.net> for reporting
1170 the bug.
1171
1172 2. Fixed a readline-related bug which prevented
1173 'cat DUMPFILE | restore -i -f -' from working. Thanks
1174 to Charles Karney <karney@users.sourceforge.net>
1175 for the bug report.
1176
1177 3. Changed a few "panic" into "exit", causing restore to
1178 be more stable against some attacks (like the last one
1179 reported on Bugtraq, although the last version of restore
1180 was not vulnerable - just dumped core). Thanks to
1181 Andreas Hasenack <andreas@conectiva.com.br> for reporting
1182 the bugs to me.
1183
1184 4. Removed the suid-root bit on dump and restore in the
1185 default build (and generated RPMs). It should be safer
1186 now. Users who need the suid-root capabilities in order
1187 to make network backups should read first the man page
1188 of dump and enable the suid bit manually.
1189
1190 5. Added -ltermcap to the compile parameters for restore
1191 when using readline support, in order to make the compile
1192 process work on some systems (SuSE ?). Thanks to
1193 Patrik Schindler <poc@pocnet.net> for reporting the bug.
1194
1195 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
1196 ====================================================================
1197
1198 1. The -F script is called now *only* at the end of a tape,
1199 not at the end of the dump. Thanks to Christian Haul
1200 <haul@informatik.tu-darmstadt.de> for the bug report.
1201
1202 Normally, the device name and the current volume number
1203 are passed on the command line of the script. However,
1204 if you want the old style script (with no arguments
1205 passed on the command line), you can enable it in
1206 configure with the --enable-oldstylefscript.
1207
1208 2. Use posix signal handling to preserve dump functionality
1209 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
1210 the patch.
1211
1212 3. Made the exit code of restore in case of a 'C'ompare
1213 command reflect the result of the compare. An exit status
1214 of 0 means the dump archive is correct, 1 means tape errors,
1215 2 means that some files were modified. Thanks to Kenneth Porter
1216 <shiva@well.com> for the suggestion.
1217
1218 4. Made (finally) quotes work in interactive restore.
1219
1220 5. Small fixes in order to allow dump to compile with a
1221 really old e2fsprogs version. Thanks to Ian Zimmerman
1222 <itz@speakeasy.org> for the bug report.
1223
1224 6. Add GNU readline capabilities to interactive restore.
1225 Use configure's --enable-readline flag to enable this feature.
1226 Thanks to Patrik Schindler <poc@pocnet.net> for the
1227 suggestion.
1228
1229 7. Do the compare on the fly in restore 'C' mode (this will
1230 allow not to exhaust the available /tmp space when
1231 ccmparing large files). Thanks to Kenneth Porter
1232 <shiva@well.com> for the suggestion.
1233
1234 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
1235 ====================================================================
1236
1237 1. Fixed some several duplicate 'DUMP: DUMP:' in the
1238 output of dump.
1239
1240 2. Corrected the estimation of blocks to dump. Note that
1241 this is still wrong for large directory inodes, due
1242 to the size of a BSD directory entry on the tape
1243 (estimation is based on the size of the ext2 directory,
1244 which is smaller because it doesn't contain the null
1245 character at the end).
1246
1247 3. Made dump report the total number of MB written to
1248 tape at the end of run. Thanks to W. Reilly Cooley
1249 <wcooley@nakedape.cc> for the patch.
1250
1251 4. Added the -X option to restore giving the possibility
1252 to read the names of the files to be extracted/listed
1253 from a text file (in addition of the command line).
1254 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
1255 patch.
1256
1257 5. Added the device name and the current volume number
1258 as arguments to the end of tape script (dump -F option).
1259
1260 6. Made the multi-volume dump work again (after having
1261 broken it in 0.4b15).
1262
1263 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1264 ===================================================================
1265
1266 1. Added a prompt command in interactive restore mode. Thanks
1267 to Andreas Dilger <adilger@home.com> for the patch.
1268
1269 2. Fixed a buffer overflow problem in dump (caused by
1270 not checking the size of the filesystem parameter).
1271 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1272 reporting this on Bugtraq (and to several dump users
1273 who forwarded me his mail).
1274
1275 3. Added the '-F script' option to dump in order to
1276 launch a script at the end of each tape (to be used
1277 with a tape changer, or to notify the sysadmin by
1278 pager etc.).
1279
1280 4. Fixed a bug in restore compare code caused by the changes
1281 I made in 0.4b14.
1282
1283 5. Fixed the treatment of options using the old BSD syntax
1284 in both dump and restore.
1285
1286 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1287 =======================================================================
1288
1289 1. Fixed a bug in dump which may have caused invalid deleted
1290 directories to be dumped out if they were deleted after the
1291 mapping pass. This could occure on active filesystem and lead
1292 to heap corruption (causing dump malfunction in many possible ways).
1293 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1294 bug and submitting the patch.
1295
1296 2. Fixed the handling of the filesystem parameter in dump. A
1297 '/mnt/disk' parameter caused the disk contents to be dumped,
1298 but a '/mnt/disk/' parameter caused the mountpoint directory
1299 to be dumped (generally an empty directory).
1300
1301 3. Improved the output of dump in order to tell which directory
1302 it is currently dumping (when dumping a subtree).
1303
1304 4. Added the '-e' exclude inode option to dump. Thanks to
1305 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1306
1307 5. Added a REPORTING-BUGS file in order to provide a guide
1308 on how to correctly report a bug in dump/restore.
1309
1310 6. Fixed a restore problem when restoring a hard link to an inode
1311 having the immutable or append-only attribute set. Thanks to
1312 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1313
1314 7. Fixed a compatibility problem between dumps made on little
1315 endian machines (the format was correct) and big endian
1316 machines (the format was incorrect). This fix break the
1317 compatibility with the older dumps made on big endian
1318 machines (sparc, m86k, ppc etc). For the first time in
1319 linux dump's history (I believe), the dumps made by *BSD,
1320 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1321 so interchangeable. Thanks to Rob Cermak
1322 <cermak@ahab.rutgers.edu> for submitting the bug and
1323 helping me test the fix.
1324
1325 8. Fixed the way dump reports the remaining percent/time, if
1326 the number of blocks actually dumped exceeds the estimated
1327 number of blocks. Thanks to Jean-Paul van der Jagt
1328 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1329
1330 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1331 ======================================================================
1332
1333 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1334 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1335
1336 2. Removed the requirement to build the RPM as root from the
1337 spec file. Thanks to Christian Weisgerber
1338 <naddy@mips.rhein-neckar.de> for submitting this.
1339
1340 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1341 causing dump to block when dumping really huge filesystems.
1342 Many thanks to Patrik Schindler <poc@pocnet.net> for
1343 helping me find this bug.
1344
1345 4. Fixed the treatment for an interrupt signal when dump access
1346 the remote tape through RSH. Thanks to Christian Weisgerber
1347 <naddy@mips.rhein-neckar.de> for providing the patch.
1348
1349 5. Fixed a bug which was causing dump/restore to display
1350 garbage characters instead of the remote host name.
1351
1352 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1353 =====================================================================
1354
1355 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1356 <kukuk@suse.de> for submitting the patch.
1357
1358 2. Fix for the exit code when using the size estimate option of
1359 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1360 submitting the patch.
1361
1362 3. Handle EINTR in atomical reads/writes in dump, which was causing
1363 dump to fail on some systems. Thanks to Eric Jergensen
1364 <eric@dvns.com> for reporting the bug and submitting the patch.
1365
1366 4. Handle more than 16 characters for the device names in dumpdates.
1367 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1368 tracking down the problem and proposing the solution.
1369
1370 5. Fixed a bug in dump which prevented the creation of the
1371 dumpdates file when doing a 0-level dump without already
1372 having a dumpdates file. Thanks to Patrik Schindler
1373 <poc@pocnet.net> for reporting the bug.
1374
1375 6. Changed the way dump 'S' flag reports the size estimate
1376 from number of blocks into bytes (making it compatible
1377 with the Solaris version, and simplifying things for
1378 amanda users). Thanks to Jason L Tibbitts III
1379 <tibbs@math.uh.edu> for reporting the bug.
1380
1381 7. Fixed a compatibility problem in linux/alpha dump tape format.
1382 Now the linux/alpha dump are (again) compatible with the
1383 other dump formats. But this breaks compatibility with
1384 older dumps made on alpha. Thanks to Mike Tibor
1385 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1386
1387 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1388 ======================================================================
1389
1390 1. Added a '--enable-kerberos' to configure.
1391
1392 2. Added a 'S' option to dump which determines the amount of space
1393 that is needed to perform the dump without actually doing it, similar
1394 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1395 <cermak@ahab.rutgers.edu>.
1396
1397 3. Added a 'M' multi-volume option to dump and restore which enables
1398 dumping to multiple files (useful when dumping to an ext2
1399 partition to make several dump files in order to bypass the 2GB
1400 file size limitation). The 'f' argument is treated as a prefix and
1401 the output files will be named <prefix>001, <prefix>002 etc. With
1402 the 'M' flag, restore automatically selects the right file without
1403 asking to enter a new tape each time.
1404
1405 4. Fixed a memory leak which was causing dump to grow very big
1406 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1407 Fearon <jasonf@netrider.org.au> for reporting the bug.
1408
1409 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1410 ======================================================================
1411
1412 1. Make configure test if the system glob routines support
1413 extended syntax (ALTDIRFUNC). If not, use the internal glob
1414 routines instead of system ones. Thanks to Bernhard Sadlowski
1415 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1416 and helping me resolve this and other minor libc5 compiling
1417 glitches.
1418
1419 2. Fix a problem when dumping a ext2fs with the 'filetype'
1420 feature enabled. Thanks to Patrick J. LoPresti
1421 <patl@cag.lcs.mit.edu> for reporting the bug and to
1422 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1423
1424 3. Made the nodump flag work on directories. A directory which
1425 has the nodump flag gets never dumped, regardless of its
1426 contents.
1427
1428 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1429 which allows dump on an active ext3 filesystem. However, this
1430 is a "quick and dirty" patch which enables backup of an ext3
1431 filesystem through the ext2 compatibility (by ignoring the
1432 NEEDS_RECOVERY bit). The journal file is not recognized and
1433 it is dumped (it should not).
1434
1435 5. Test the superblock compatibility flags when dumping, in order
1436 to be sure that we know how to deal with specific features.
1437
1438 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1439 ====================================================================
1440
1441 1. Use lchown instead of chown, fixing a possible security problem
1442 when restoring symlinks (a malicious user could use this
1443 to deliberately corrupt the ownership of important system files).
1444 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1445 this and providing the patch.
1446
1447 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1448 ====================================================================
1449
1450 1. Put dump sources under CVS, added Id tags in all files so
1451 one can use 'ident' on binary files.
1452
1453 2. Added the dump/restore version in the usage text so one can
1454 easily verify the version he is using.
1455
1456 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1457 a va_start/va_end problem on linux-ppc (always call va_start
1458 va_end in pairs each time we use a vararg function).
1459
1460 4. Added again the DT_* constants because old libc does not
1461 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1462 for submitting the bug report.
1463
1464 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1465 this should enable dumping big (huge) filesystems.
1466
1467 6. Added the RSH environment variable in order to be able to
1468 use a rsh replacement like ssh when doing remote backups (and
1469 bypass the security limitations of rcmd). Now you can do remote
1470 backups without being root (or making dump setuid root).
1471
1472 7. Modified again the way dumpdates works. For incremental dumps,
1473 we need to read dumpdates even if we are not using 'u' option.
1474 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1475 this should work.
1476
1477 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1478 ===================================================================
1479
1480 1. Removed the 'k' flag from the restore 'about' text if kerberos
1481 was not compiled in.
1482
1483 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1484 to them (fsetflags takes a char*, setflags an open fd!).
1485
1486 3. (f)setflags is called only if the flags aren't empty. If the
1487 file is a special file, a warning is printed, because changing
1488 flags implies opening the device. Normally, a special file
1489 should not have any flag... (Debian bug #29775, patch provided
1490 by Abhijit Dasgupta <abhijit@ans.net>).
1491
1492 4. Made possible to dump a file system not mentioned in /etc/fstab.
1493 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1494
1495 5. Changed the default behaviour to not create dumpdates
1496 unless 'u' option is specified. Removed the old "debian-patch"
1497 which provided the same thing. (Debian bug #38136, #33818).
1498
1499 6. Removed all those dump*announce, since they were getting old...
1500
1501 7. Added warning messages if dumpdates does not exist and
1502 when an inferior level dump does not exist (except for a level 0
1503 dump).
1504
1505 8. Debugged the glob calls in interactive mode: restore used a
1506 dirent struct which was different from the /usr/include/dirent.h
1507 one (this used to work, is it a glibc2 change?), so none of the
1508 compat glob (which used /usr/include/dirent.h) or the system glob
1509 worked. Restore use now the system dirent (and the system
1510 DT_* constants), which are compatible with BSD ones.
1511
1512 9. Added a configure flag (--with-dumpdatespath) to specify
1513 the location of dumpdates file. By default, it is
1514 /etc/dumpdates.
1515
1516 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1517 included the current date/version in man pages.
1518
1519 11. Corrected the estimation of remaining time when
1520 the operator doesn't change the tapes quickly enough. This
1521 was an old bug, I thought I corrected it, and discovered
1522 that in fact it was corrected in two different places, so
1523 the results canceled each other...
1524
1525 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1526 ===================================================================
1527
1528 1. Integrated multiple patches from RedHat, Debian and SuSE:
1529
1530 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1531 isn't specified.
1532 - several fixes in the man pages.
1533 - update the default tape device to /dev/st0.
1534 - many updates for Linux Alpha (byte ordering, size_t etc).
1535 - buffer overruns.
1536 - use environment variable for TMPDIR (instead of /tmp).
1537 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1538 - workaround egcs bug (RedHat bugs #4281 and #2989).
1539 - wire $(OPT) throughout Makefile's.
1540
1541 2. Upgrade the dump revision to 1, making possible to dump filesystems
1542 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1543
1544 3. Fix some compile warnings, prototype all functions.
1545
1546 4. Use glibc err/glob instead of internal compatibility
1547 routines (only if available).
1548
1549 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1550 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1551
1552 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1553 ======================================================================
1554
1555 1. Integrated the changes from FreeBSD-3.1-RELEASE
1556 (mostly bug fixes, buffer overruns, dump has now an "automatic
1557 tape length calculation" flag, dump/restore can use kerberos now
1558 (this is NOT tested), use environment variables for TAPE and
1559 RMT etc.).
1560
1561 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1562
1563 3. Corrected a bug in restore when using 'C' option with multi-volumes
1564 tapes (files splited accros two tapes give "size changed" errors
1565 when comparing).
1566
1567 4. Corrected the long standing bug when dumping multiple tapes.
1568 This works for me, needs further testing.
1569
1570 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1571 ====================================================================
1572
1573 1. Dump now runs correctly on kernels 2.1.x
1574 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1575
1576 Changes between versions 0.4b2 and 0.4b3
1577 ========================================
1578
1579 1. Use realpath() if available
1580
1581 2. Report statistics
1582
1583 Changes between versions 0.4b1 and 0.4b2
1584 ========================================
1585
1586 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1587 the patch)
1588
1589 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1590
1591 3. Fixed configure.in to correctly handle --enable-rmt
1592
1593 Changes between versions 0.3 and 0.4b1
1594 ======================================
1595
1596 1. Integrated the changes from 4.4BSD-Lite2
1597
1598 2. Integrated the patches from Debian and Red Hat
1599
1600 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1601
1602 4. Changed dump to use the Ext2fs library to get block addresses. This
1603 should solve the endianness problem on SparcLinux.
1604
1605 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1606 distribution's one) to use autoconf
1607
1608 6. Fixed a few minor bugs
1609
1610 Changes between versions 0.2e and 0.2f
1611 ======================================
1612
1613 1. Added the creation of named pipes (fifos) in restore.
1614
1615 2. Added the -N flag in the restore manual page.
1616
1617 3. Added the file kernel.patch which contains the llseek() optimization
1618 patch for 1.2.x kernels.
1619
1620 4. Fixed a bug in the restoration of symbolic links: owner and group were
1621 not restored.
1622
1623 5. Integrated some changes from FreeBSD 2.2.
1624
1625 6. Added a call to ftruncate() after restoring each file to restore
1626 correctly files ending by a hole.
1627
1628 Changes between versions 0.2d and 0.2e
1629 ======================================
1630
1631 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1632 with owner = root (0) and group = root/wheel/whatever (0).
1633
1634 Changes between versions 0.2c and 0.2d
1635 ======================================
1636
1637 1. Dump is now able to backup 2GB+ filesystems.
1638
1639 2. Dump and restore can now be linked as static binaries.
1640
1641 Changes between versions 0.2b and 0.2c
1642 ======================================
1643
1644 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1645
1646 Changes between versions 0.2a and 0.2b
1647 ======================================
1648
1649 1. Really fixed the bug that I should have corrected in 0.2a.
1650
1651 2. Enabled optimization again.
1652
1653 Changes between versions 0.2 and 0.2a
1654 =====================================
1655
1656 1. Disabled the optimization during compilation.
1657
1658 Changes between versions 0.1 and 0.2
1659 ====================================
1660
1661 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1662 the fs_type field (actually, I modified the file fstab.c to make it
1663 use the mntent functions).
1664
1665 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1666 made by dump should be readable by the BSD restore and backups made
1667 by the BSD dump should be readable by restore. Unfortunately, this
1668 means that the dump format has changed between version 0.1 and version
1669 0.2 :-(
1670
1671 3. Dump is now able to backup a subtree, it is no longer limited to whole
1672 filesystems like the BSD version.
1673
1674 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1675 than 2 GB.
1676
1677 Changes between versions 0.0 and 0.1
1678 ====================================
1679
1680 1. Now create links rdump and rrestore during the `make install' step.
1681
1682 2. Linux port specific bugs added to the manual pages
1683
1684 3. Incorrect estimation of the number of tapes blocks fixed when doing
1685 incremental backups.
1686
1687 4. Better ls-like format in restore in interactive mode.
