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