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