3 Changes between versions 0.4b33 and 0.4b34 (released ?????????????????)
4 =======================================================================
6 1. Fixed the INSTALL file to reflect the actual install paths.
7 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
10 2. Fixed the configure script to only check for headers presence
11 instead of trying to compile them. This should fix issues
12 with old build environments. Thanks to Kari Lempiainen
13 <kari@funky.pp.fi> for reporting the bug.
15 3. Fixed restore to correctly ignore sockets when comparing
16 a dump (as socket cannot be properly restored anyway). Thanks
17 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
19 4. Fixed restore to correctly access the archive file (-A argument)
20 even when using a remote tape. Thanks to Fabrice Bellet
21 <fabrice@bellet.info> for reporting the bug.
23 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
24 =======================================================================
26 1. Added a note in the restore man page clarifying the question
27 'set the permissions on the current directory ?' asked by
28 restore at the end of treatment in -i and -x modes.
30 2. Fixed the endianess issues when reading compressed tapes.
31 Thanks to Dark Force <daq4th@users.sourceforge.net> for
32 reporting this bug and providing test cases.
34 3. Fixed the "ACL won't be dumped" warning message (which showed
35 an extra, unrelated error message). Thanks to Dragan Krnic
36 <dkrnic@lycos.com> for reporting this bug.
38 4. Made dump look first into /etc/mtab, then into /etc/fstab
39 when searching for filesystem paths. Also fixed some problems
40 caused by binding mounts or multiple block device mounts.
41 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
42 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
43 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
44 and #160305, Sourceforge bugs #618699 and #679832).
46 5. Made dump's -I option accept the value '0' meaning all the
47 read errors will be ignored. This can be useful when running
48 dump from unattended sessions (like cron jobs). Thanks to
49 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
51 6. Fixed the output of dump to indicate 'blocks' instead of
52 'tape blocks' in the various messages (blocks are always
53 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
54 made it clearly print the current blocksize at the start of
55 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
58 7. Made rmt understand long (largefiles) seeks.
60 8. Fixed build with very old versions of libext2fs, where
61 EXT2_FT_* constants were undefined.
63 9. Made dump accept the dumpdates path on the command line
64 (-D file option) instead of using only the hardcoded one.
65 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
68 10. Enabled rmt, LFS, readline, QFA options by default in
69 ./configure. Updated the configure process (new versions
70 of config.guess, config.sub etc).
72 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
73 =======================================================================
75 1. Changed dump to use fcntl(F_SETLK) style locking instead
76 of flock() when locking the dumpdates file. With the old
77 locking scheme, a local user having read rights on the
78 dumpdates file could be able to do a Denial of Service attack
79 on dump. In order to lock the dumpdates file with the new
80 scheme, the user would need to have write access on the file.
81 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
82 reporting the bug (originally a bugtraq post).
84 2. Fixed interactive 'ls' which caused spurious errors warnings
85 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
86 <jorgen_ostling@users.sourceforge.net> for reporting this
89 3. Fixed dump's estimate when dealing with sparse inodes.
91 4. Modified dump to allow setting a blocksize bigger than 32kB
92 (raised the limit to 1024kB), because newer hardware needs
93 this for proper operation. Thanks to Dirk Traenapp
94 <dtraenapp@users.sourceforge.net> for reporting this.
96 5. Fixed a bug causing Dump to stop and report an error if an
97 inode number in the exclude file was followed by some amount
98 of whitespace. Thanks to Jeffrey Sofferin
99 <sofferin@users.sourceforge.net> for reporting this bug.
101 6. Fixed a bug which caused restore, in some particular cases,
102 to ask some 'scary' questions and leave a bunch of RSTTMP
103 directories behind when restoring incremental tapes. Thanks
104 to Philippe Troin <phil@fifi.org> for reporting this bug and
105 providing the test cases.
107 7. Changed the wording when inodes are excluded from dump:
108 replaced 'Added inode 7 to exclude list' with
109 'Excluding inode 7 (resize inode) from dump', as suggested
110 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
112 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
113 ===================================================================
115 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
116 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
117 <eros@lamel.bo.cnr.it> for reporting the bug.
119 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
120 ===================================================================
122 1. Made dump print out the ext2 logical block number in case of a read
123 error, which can be given as an argument to debugfs' ncheck command,
124 in order to find out the affected inode. Added note about this
125 usage in dump's man page.
127 2. Fixed a problem in restore when reading tapes written on big
128 endian machines with very old versions of dump. The patch was
129 contributed by George Helffrich <george@geology.bristol.ac.uk>.
131 3. Fixed the tape length calculation when using large tapes
132 and compression. Thanks to Georg Lippold
133 <g_lippold@sourceforge.net> for reporting the bug.
135 4. Added a new set of examples in dump_on_cd_2 directory, based
136 on dump_on_cd examples but somewhat enhanced, supporting DVD
137 media, and localized in english and german. Thanks to
138 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
140 5. Made dump save 32 bit UID/GID. Internally, this was achieved
141 by switching from the old BSD inode format to the new BSD
142 inode format, which means that the tape format was changed.
143 However, since all restore versions out there should
144 transparently support both inode formats, the change should
145 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
148 6. Fixed a lot of warnings in the code shown when compiling
149 with 'gcc -W'. Thanks to Matthias Andree
150 <matthias.andree@stud.uni-dortmund.de> for reporting this.
152 7. Fixed a small markup bug in the dump man page. Thanks to
153 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
156 8. Rewrote entirely the man pages using the tmac.an macro
157 package (Linux man page format) instead of the original BSD
158 format. They should be now cleaner and easier to modify.
160 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
161 ==================================================================
163 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
164 non Linux clients were misinterpreted. The description of the problem
165 (incompatible numbering in Linux mtio opcodes) is documented at
166 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
167 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
168 providing an excellent, cross-platform replacement for rmt in his
171 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
172 which caused restore to fail when the inode maps were not entirely
173 contained on the first volume (when using really small volumes or
174 when dumping a huge number of inodes).
176 3. Fixed a problem in dump, where files in subdirectories of directories
177 that have the nodump flag set (or being excluded with -e/-E) were
178 sometimes incorrectly dumped (instead of being excluded). The original
179 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
180 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
181 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
182 help testing the patch.
184 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
185 which makes one able to pipe the output of dump, by the net, to
186 a remote CD-burner server.
188 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
189 and use GNU's symbolic syntax over rmt instead of numerical values
190 to assure multiple platform compatibility.
192 6. Documented the -d option in restore.
194 7. Added a -v (verbose) mode to dump. For now it just prints the number
195 of the inode being dumped, but this could evolve in future versions
196 to include interesting debugging output.
198 8. Added a -o flag to restore, which automatically restores the current
199 directory permissions in -i or -x mode, without asking the operator
200 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
201 and Peter Samuel <peters@e-smith.com>.
203 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
204 ====================================================================
206 1. Fixed a bug in the QFA feature which could have caused
207 a bad tape positionning on restore (causing extra delays in
208 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
210 2. Added a small note in the dump man page specifying that
211 there should be no white space between the option letter and
212 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
214 3. Made restore work with older versions of the readline library,
215 by checking in configure for several extended symbols. Restore
216 can now be compiled with a readline as old as the 2.0 release
217 (though it may be a good idea to upgrade it to a more recent
218 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
219 reporting the build failures.
221 4. Fixed a performance problem with the QFA file creation in
222 dump, which made unnecessary seeks on the tape slowing down
223 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
224 reporting this issue.
226 5. Removed the inclusion of some kernel headers in the dump
227 source, which prevented the compile in some kernel/glibc
228 headers/architecture combination. Thanks to Bdale Garbee
229 <bdale@gag.com> for reporting the bug.
231 6. Added the appropriate error message when dump fails to
232 open the output file for writing. Thanks to Amith Varghese
233 <amithv@yahoo.com> for reporting this bug.
235 7. Made restore able to understand large Solaris ufsdump tapes
236 (containing inodes bigger than 4194304). Sun have introduced
237 an "extension" to the dump tape format when dealing with
238 those inodes, which was uncorrectly handled by Linux restore.
239 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
240 providing a test case.
242 8. Added the -m parameter to dump which optimises the output for
243 inodes having been changed but not modified since the last dump
244 ('changed' and 'modified' have the meaning defined in stat(2)).
245 For those inodes, dump will save only the metadata, instead of
246 saving the entire inode contents. Inodes which are either
247 directories or have been modified since the last dump are saved
248 in a regular way. Uses of this flag must be consistent, meaning
249 that either every dump in an incremental dump set have the flag,
252 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
253 =======================================================================
255 1. Fixed behaviour of dump when exceeding resource limits
258 2. Added the -L flag to restore to allow the user to specify a
259 maximal allowed number of miscompares when using restore
260 with the -C option to check the backup.
262 3. Detailed the manual entry for the -N option of restore.
264 4. Added the -a flag to restore to make able doing unattended
265 restores in -i or -x mode (automatically walks through the
266 multiple dump volumes).
268 5. Extended the QFA mode to work with local files and/or
269 remote tapes and files. This way, restore can know in advance
270 the tape number and the offset for the inodes to extract and
271 can minimize the extraction time by seeking directly to the
274 6. Added the -A <archive> option to both dump and restore,
275 which makes dump to archive a dump table-of-contents in
276 the specified file to be used by restore to determine
277 whether a file is in the dump file that is being restored.
278 (the archive file syntax is also compatible with the
279 Solaris ufsdump generated one).
281 7. Small fix in restore making it able to read some (broken ?)
282 Solaris ufsdump tapes.
284 8. Fixed dump to correctly recognise the root filesystem when using
285 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
286 for reporting this bug.
288 9. Added the -P <file> option to restore to create a
289 Quick File Access file from an already made dump. Patch
290 contributed by Uwe Gohlke <uwe@ugsoft.de>.
292 10. Made restore compile and run on Solaris, making it a
293 possible replacement for the standard ufsrestore. Port was
294 contributed by Uwe Gohlke <uwe@ugsoft.de>.
296 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
297 =====================================================================
299 1. Added a set of backup scripts from Eugenio Diaz
300 <getnito@yahoo.com> in the examples section. It features
301 automatic (cron based) full and incremental dumping of
302 several filesystems on a separate filesystem.
304 2. Fixed a off-by-one miscalculation which disabled dumping
305 a one letter subdirectory. Thanks to Chris Siebenmann
306 <cks@utcc.utoronto.ca> for reporting the bug.
308 3. Fixed several restore bugs occuring when trying to
309 restore some missing files on the tape. Thanks to Chris
310 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
312 4. Fixed --with-ldopts configure argument passing, installing from
313 a separate object directory, makefile cleanups contributed
314 by <splite@purdue.edu>.
316 5. Fix a bug which could caused, in some conditions, the highest
317 number inode of a filesystem, to not be dumped. Many thanks
318 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
321 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
322 =======================================================================
324 1. Added a mini howto from Patrick Walsh in the examples
327 2. Minor man pages syntax corrections. Thanks to
328 Chris Danis <screechco@home.com> for reporting the bugs.
330 3. Added a script from David B. Peterson <dave@toppledwagon.com>
331 to the examples section. It features dumping several
332 filesystems to a remote tape drive upon ssh.
334 4. Added a patch provided by Richard Jones <rich@annexia.org>
335 which allows BRADEMAX (number of read errors tolerated by
336 dump) to be adjusted using the -I option.
338 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
339 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
342 6. Add the -l option to restore to specify if, when doing a
343 remote restore, the file used to access the backup is a
344 regular file (the defaults being a tape drive). Restore needs
345 to know this information when reading a remote compressed
346 dump. Previously, this information was autodetected, but
347 the autodetection code fails (with ioctl: Inappropriate ioctl
348 for device) when using a non Linux remote box. Thanks to
349 many users and especially to Eros Albertazzi
350 <eros@lamel.bo.cnr.it> for reporting this.
352 7. Found a workaroung for the dump deadlock problem (3 childs
353 stuck in pause(), father in read()). The workaround seems
354 to work for me and several beta-testers. If it doesn't work
355 for you, please report back.
357 8. Updated the RPM spec file (BuildPrereq, URL etc).
359 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
360 ========================================================================
362 1. Fixed the permissions of a newly created QFA file by dump.
364 2. Cleaned up the source of dump (the external variables
365 definition was a complete mess, making possible to have
368 3. Fixed restore to use the full tape volume path when doing
369 a compare (since it changes the working directory to the
370 filesystem being compared in the process).
372 4. Added the -q option to dump which makes dump abort
373 whenever it needs operator attention. It should be
374 easier to use dump in scripts with this option.
376 5. Detect the use of incompatible options to dump and
377 refuse them (like -a and -B options together).
379 6. Added bzip2 compression to dump/restore (use option -j level
380 to select it). Note that you will need a restore version
381 >= 0.4b24 in order to restore a bzip2 compressed dump.
382 The same warning as for the zlib compression applies:
383 the tape format of a bzip2 dump is not compatible with the
384 original BSD tape format.
386 7. Fixed a overflow problem in dump corrupting the dump when
387 very large files were encountered. Thanks to Vladimir Nadvornik
390 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
391 kernel buffer/page cache before starting the dump, helping
392 a bit those who use dump on mounted filesystems. Thanks to
393 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
396 9. Updated the RPM spec file following the RedHat changes
397 (dynamically linked binaries now in /usr/sbin etc).
399 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
400 which enables restore to recognise multi volume compressed dumps
401 done on CD. Included his scripts for dump (which pipe the dump
402 output directly into cdrecord) and restore. There is now
403 possible to to backups to CD on the fly!
405 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
406 ===================================================================
408 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
409 Marcus Meissner (Caldera International Security Dept.).
411 2. Implement the Sun rmt extended protocol. Patch submitted
412 by Ian Gordon <iangordon@users.sourceforge.net>.
414 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
415 the linux kernel header. This ensures that dump always has the
416 latest version of this file. Patch submitted by
417 Andreas Dilger <adilger@turbolinux.com>.
419 4. Report any filesystem present in either /etc/fstab with a
420 positive passno or /etc/dumpdates in dump -w output.
421 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
423 5. Fixed the looping problem in dump introduced in the
426 6. Changed the -B option of dump to limit the size of
427 _compressed_ output per volume if compression is on.
428 Patch contributed by Helmut Jarausch
429 <jarausch@igpm.rwth-aachen.de>. Note however that, since
430 it is impossible to predict the size of the compressed
431 data before doing the compression, the -B limit is a bit
434 7. Fixed a bug in reading the operator typed file/tape path for
435 the next volume in restore.
437 8. Implemented a "-F script" option to restore which permits the
438 user to specify a script which will be launched at the
439 beginning of each tape, useful for automatic programming of
440 tape changers for example. See the restore man page for the
441 script parameters and return codes.
443 9. Small fix for the QFA routines provided by Uwe Gohlke
444 <uwe@ugsoft.de>, and some recommendations for QFA uses in
447 10. Fixed the multivolume restoring where making a mistake
448 to the 'Mount next tape' prompt caused several blocks to
451 11. Enhanced the -e option of dump to take as a parameter a
452 comma separated list of inode numbers.
454 12. Added the -E option to dump which specify a file containing
455 inode numbers to exclude from the dump.
457 13. Fixed the compressed multi-volume dump + restore.
459 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
460 ==================================================================
462 1. Made dump report the number of blocks dumped per volume.
463 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
465 2. Fix a bug in dump where waiting too much at the 'change volumes'
466 question caused the volume to be rewritten. Thanks to
467 Graham Reed <greed@users.sourceforge.net> for reporting the
468 bug and providing a patch.
470 3. Added a compression option to dump, contributed by Jerry
471 Peters <gapeters@worldnet.att.net>.
473 WARNING: the compression works only on files/pipes and
474 drives supporting variable block size.
476 WARNING2: tapes created using the compression feature are
477 incompatible with the standard dump tape format, and a
478 version of restore >= 0.4b22 will be needed for extraction.
480 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
481 architectures. Thanks to Paul Slootman <paul@debian.org> for
482 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
485 5. Many cleanups (CPP defines, const char warnings, check of
486 ext2fs COMPAT flags, time_t cleanups, added libext2 version
487 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
489 6. Made --prefix option work in configure. All the install path
490 are now based on the configure parameters.
492 7. Added the Quick File Access mode in dump/restore, contributed
493 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
494 a file tape position for each inode, and this file is used by
495 restore (if called with parameter Q and the filename)
496 to directly position the tape at the file restore is currently
497 working on. This saves hours when restoring single files from
498 large backups, saves the tapes and the drive's head. Use
499 --enable-qfa option of configure to compile in the QFA support.
501 8. Added the possibility to dump several files and directories
502 in a single invocation of dump. Thanks to Uwe Gohlke
503 <uwe@ugsoft.de> for implementing this option.
505 9. Fixed the dumping and restoring of files with holes
506 (files ending with holes didn't get dumped or restored
509 10. Fixed a socket descriptor leak in dump, which leaved opened
510 3 file descriptors per dump process (and there is one dump
513 11. Fixed dump large file system support, by explicit use of
514 open64/lseek64/etc functions (explicit use needed because
515 e2fsprogs libraries don't behave well when compiled with
516 FILE_OFFSET_BITS=64).
518 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
519 ======================================================================
521 1. Fixed some bugs in the dump -w|-W logic introduced by
522 the previous version. Thanks to Andreas Dilger
523 <adilger@turbolinux.com> for his help on this one.
525 2. Fixed again a compilation problem when using old e2fs
526 headers (filesystem label related). Thanks to many users
527 who reported this stupid error.
529 3. Fixed a build problem on old lib5 based systems dealing with
530 _PATH_MNTTAB being undefined. Thanks to John Adams
531 <johna@onevista.com> for reporting the bug.
533 4. Improved the error detection in restore when creating
534 the temporary files in TMPDIR. Now restore will corectly
535 report a 'no space left on device' error instead of
536 strange errors which could imply an archive corruption.
537 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
538 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
540 5. Added the throughput information in dump's progression
541 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
544 6. Use libext2fs's inode scanning routines, which are particularly
545 robust when dealing with errors (especially when having some
546 bad blocks on the filesystem). Many thanks to Colin
547 <colin@horizon.com> for reporting the bug, investigating
548 the issues, finding a workaround, writing the patch and
549 fully testing it... (of course, if this patch will break
550 anything, he is to blame for :-)).
552 7. Made dump and restore LFS aware. Dump can dump a filesystem
553 containing large files, generate a large file on output and
554 restore can restore them. This feature is not enabled by
555 default, use --enable-largefile option of configure to enable
556 it (you need to have a LFS aware glibc though). Thanks to
557 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
558 and to Theodore T'so <tytso@valinux.com> for his always
561 8. Made dump ask upon a tape write error if it should rewrite
562 the current volume (assume this is a bad tape) or if it should
563 assume an end-of-tape condition (useful for tape drives which
564 behaves badly at the end of the tape). Thanks to Andreas
565 Dilger <adilger@turbolinux.com> for the suggestion.
567 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
568 =======================================================================
570 1. Fixed a small compilation problem due to a change
571 in the definintion of the struct sigaction in
572 glibc 2.0 / libc5. Thanks to Gunther Schlegel
573 <schlegel@riege.de> for reporting the bug and to
574 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
577 2. Modified the label and uuid analysis in order to be
578 self-contained (independant of kernel/libc headers). This
579 should fix the compile with older kernel/libc headers and
580 will preserve the functionality. Thanks to Bernhard Erdmann
581 <bernhard.erdmann@gmx.de> for reporting the bug.
583 3. The 'exclude inode' option, if applied to a directory
584 inode, excludes now correctly all the leaves of this
585 directory. Thanks to John R. Dennison
586 <gerdesas@users.sourceforge.net> for reporting the bug.
588 4. Fixed the '-e' option to disable the possibility
589 to exclude the root inode (which causes the dumps to
590 be unreadable by restore). Prevented array overflow
591 when multiple -e options are used.
593 5. Fixed dump to correctly interpret a filesystem argument
594 which is a mountpoint and it is not an absolute path
595 (as specified in the fstab). Thanks to Bernhard R. Erdmann
596 <be@berdmann.de> for reporting the bug.
598 6. Made dump able to backup files larger than 2 GB. Note that
599 dump still doesn't cope with files larger than 4 GB.
601 7. Restore the real uid and gid before invoking an external
602 RSH program (big hole when dump or restore is suid root!).
604 8. Get the values for the default tape device and the location
605 of fstab file from the system headers. Thanks to
606 Andreas Dilger <adilger@turbolinux.com> for the patch.
608 9. Made dump -w|-W report all recognized filesystems
609 present in either /etc/fstab or /etc/dumpdates, and present
610 the list in the same order as in fstab file. Thanks
611 to Andreas Dilger <adilger@turbolinux.com> for the patch.
613 10. Made dump's -a (automatic end of tape detection) the
614 default. Specifying one of -B, -c, -d or -s options will
615 override the EOM detection. Thanks to Andreas Dilger
616 <adilger@turbolinux.com> for the patch.
618 11. Save the ext2 filesystem label into the dump volume label.
619 Specifying a volume label on the command line (-L option)
620 will override this feature. Thanks to Andreas Dilger
621 <adilger@turbolinux.com> for the patch.
623 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
624 =====================================================================
626 1. Fixed the signal handling in dump (which I broke in 0.4b17)
627 which was causing several strange dump failures (dump
628 hanged or segmentation faults etc).
630 2. Specified the default blocksize in the dump man page.
632 3. Changed two info messages of restore to be written on stdout
633 instead of stderr in order to leave stderr only for errors
634 or warnings. Thanks to Stephen Atwell
635 <satwell@urbana.css.mot.com> for the suggestion.
637 4. Corrected an off by one calculation which prevented
638 dumping a directory having a 1 character name length.
639 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
640 for reporting the bug.
642 5. Reinforce dump in order to allow only level 0 and no
643 -u option when dumping a subdirectory, and document
644 this in the man page. Thanks to Bernhard Erdmann
645 <bernhard.erdmann@gmx.de> for reporting the bug.
647 6. Fixed a small harmless bug in restore which caused
648 in some conditions hard links to be restored several
649 times (therefore generation some warning messages).
650 Thanks to Kenneth Porter <shiva@well.com> for
653 7. Updated the RPM spec file to the latest RedHat version,
654 providing FHS packaging and other cosmetic changes.
655 You will need RPM version >= 3.0.5 in order to build the RPM.
657 8. Updated the configure script to check for libtermcap
658 before checking for libreadline, because we need this
659 library in order to compile the readline support.
661 9. Made dump understand the LABEL= and UUID= notation
662 both in /etc/fstab and on the command line. Note that
663 you will need the /proc filesystem in order to use
664 these notations. Thanks to Erik Troan <ewt@redhat.com>
665 for providing the patch.
667 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
668 ===================================================================
670 1. Fixed a potential buffer overflow in restore. Thanks
671 to Stan Bubrouski <satan@fastdial.net> for reporting
674 2. Fixed a readline-related bug which prevented
675 'cat DUMPFILE | restore -i -f -' from working. Thanks
676 to Charles Karney <karney@users.sourceforge.net>
679 3. Changed a few "panic" into "exit", causing restore to
680 be more stable against some attacks (like the last one
681 reported on Bugtraq, although the last version of restore
682 was not vulnerable - just dumped core). Thanks to
683 Andreas Hasenack <andreas@conectiva.com.br> for reporting
686 4. Removed the suid-root bit on dump and restore in the
687 default build (and generated RPMs). It should be safer
688 now. Users who need the suid-root capabilities in order
689 to make network backups should read first the man page
690 of dump and enable the suid bit manually.
692 5. Added -ltermcap to the compile parameters for restore
693 when using readline support, in order to make the compile
694 process work on some systems (SuSE ?). Thanks to
695 Patrik Schindler <poc@pocnet.net> for reporting the bug.
697 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
698 ====================================================================
700 1. The -F script is called now *only* at the end of a tape,
701 not at the end of the dump. Thanks to Christian Haul
702 <haul@informatik.tu-darmstadt.de> for the bug report.
704 Normally, the device name and the current volume number
705 are passed on the command line of the script. However,
706 if you want the old style script (with no arguments
707 passed on the command line), you can enable it in
708 configure with the --enable-oldstylefscript.
710 2. Use posix signal handling to preserve dump functionality
711 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
714 3. Made the exit code of restore in case of a 'C'ompare
715 command reflect the result of the compare. An exit status
716 of 0 means the dump archive is correct, 1 means tape errors,
717 2 means that some files were modified. Thanks to Kenneth Porter
718 <shiva@well.com> for the suggestion.
720 4. Made (finally) quotes work in interactive restore.
722 5. Small fixes in order to allow dump to compile with a
723 really old e2fsprogs version. Thanks to Ian Zimmerman
724 <itz@speakeasy.org> for the bug report.
726 6. Add GNU readline capabilities to interactive restore.
727 Use configure's --enable-readline flag to enable this feature.
728 Thanks to Patrik Schindler <poc@pocnet.net> for the
731 7. Do the compare on the fly in restore 'C' mode (this will
732 allow not to exhaust the available /tmp space when
733 ccmparing large files). Thanks to Kenneth Porter
734 <shiva@well.com> for the suggestion.
736 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
737 ====================================================================
739 1. Fixed some several duplicate 'DUMP: DUMP:' in the
742 2. Corrected the estimation of blocks to dump. Note that
743 this is still wrong for large directory inodes, due
744 to the size of a BSD directory entry on the tape
745 (estimation is based on the size of the ext2 directory,
746 which is smaller because it doesn't contain the null
747 character at the end).
749 3. Made dump report the total number of MB written to
750 tape at the end of run. Thanks to W. Reilly Cooley
751 <wcooley@nakedape.cc> for the patch.
753 4. Added the -X option to restore giving the possibility
754 to read the names of the files to be extracted/listed
755 from a text file (in addition of the command line).
756 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
759 5. Added the device name and the current volume number
760 as arguments to the end of tape script (dump -F option).
762 6. Made the multi-volume dump work again (after having
763 broken it in 0.4b15).
765 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
766 ===================================================================
768 1. Added a prompt command in interactive restore mode. Thanks
769 to Andreas Dilger <adilger@home.com> for the patch.
771 2. Fixed a buffer overflow problem in dump (caused by
772 not checking the size of the filesystem parameter).
773 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
774 reporting this on Bugtraq (and to several dump users
775 who forwarded me his mail).
777 3. Added the '-F script' option to dump in order to
778 launch a script at the end of each tape (to be used
779 with a tape changer, or to notify the sysadmin by
782 4. Fixed a bug in restore compare code caused by the changes
785 5. Fixed the treatment of options using the old BSD syntax
786 in both dump and restore.
788 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
789 =======================================================================
791 1. Fixed a bug in dump which may have caused invalid deleted
792 directories to be dumped out if they were deleted after the
793 mapping pass. This could occure on active filesystem and lead
794 to heap corruption (causing dump malfunction in many possible ways).
795 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
796 bug and submitting the patch.
798 2. Fixed the handling of the filesystem parameter in dump. A
799 '/mnt/disk' parameter caused the disk contents to be dumped,
800 but a '/mnt/disk/' parameter caused the mountpoint directory
801 to be dumped (generally an empty directory).
803 3. Improved the output of dump in order to tell which directory
804 it is currently dumping (when dumping a subtree).
806 4. Added the '-e' exclude inode option to dump. Thanks to
807 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
809 5. Added a REPORTING-BUGS file in order to provide a guide
810 on how to correctly report a bug in dump/restore.
812 6. Fixed a restore problem when restoring a hard link to an inode
813 having the immutable or append-only attribute set. Thanks to
814 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
816 7. Fixed a compatibility problem between dumps made on little
817 endian machines (the format was correct) and big endian
818 machines (the format was incorrect). This fix break the
819 compatibility with the older dumps made on big endian
820 machines (sparc, m86k, ppc etc). For the first time in
821 linux dump's history (I believe), the dumps made by *BSD,
822 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
823 so interchangeable. Thanks to Rob Cermak
824 <cermak@ahab.rutgers.edu> for submitting the bug and
825 helping me test the fix.
827 8. Fixed the way dump reports the remaining percent/time, if
828 the number of blocks actually dumped exceeds the estimated
829 number of blocks. Thanks to Jean-Paul van der Jagt
830 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
832 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
833 ======================================================================
835 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
836 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
838 2. Removed the requirement to build the RPM as root from the
839 spec file. Thanks to Christian Weisgerber
840 <naddy@mips.rhein-neckar.de> for submitting this.
842 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
843 causing dump to block when dumping really huge filesystems.
844 Many thanks to Patrik Schindler <poc@pocnet.net> for
845 helping me find this bug.
847 4. Fixed the treatment for an interrupt signal when dump access
848 the remote tape through RSH. Thanks to Christian Weisgerber
849 <naddy@mips.rhein-neckar.de> for providing the patch.
851 5. Fixed a bug which was causing dump/restore to display
852 garbage characters instead of the remote host name.
854 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
855 =====================================================================
857 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
858 <kukuk@suse.de> for submitting the patch.
860 2. Fix for the exit code when using the size estimate option of
861 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
862 submitting the patch.
864 3. Handle EINTR in atomical reads/writes in dump, which was causing
865 dump to fail on some systems. Thanks to Eric Jergensen
866 <eric@dvns.com> for reporting the bug and submitting the patch.
868 4. Handle more than 16 characters for the device names in dumpdates.
869 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
870 tracking down the problem and proposing the solution.
872 5. Fixed a bug in dump which prevented the creation of the
873 dumpdates file when doing a 0-level dump without already
874 having a dumpdates file. Thanks to Patrik Schindler
875 <poc@pocnet.net> for reporting the bug.
877 6. Changed the way dump 'S' flag reports the size estimate
878 from number of blocks into bytes (making it compatible
879 with the Solaris version, and simplifying things for
880 amanda users). Thanks to Jason L Tibbitts III
881 <tibbs@math.uh.edu> for reporting the bug.
883 7. Fixed a compatibility problem in linux/alpha dump tape format.
884 Now the linux/alpha dump are (again) compatible with the
885 other dump formats. But this breaks compatibility with
886 older dumps made on alpha. Thanks to Mike Tibor
887 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
889 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
890 ======================================================================
892 1. Added a '--enable-kerberos' to configure.
894 2. Added a 'S' option to dump which determines the amount of space
895 that is needed to perform the dump without actually doing it, similar
896 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
897 <cermak@ahab.rutgers.edu>.
899 3. Added a 'M' multi-volume option to dump and restore which enables
900 dumping to multiple files (useful when dumping to an ext2
901 partition to make several dump files in order to bypass the 2GB
902 file size limitation). The 'f' argument is treated as a prefix and
903 the output files will be named <prefix>001, <prefix>002 etc. With
904 the 'M' flag, restore automatically selects the right file without
905 asking to enter a new tape each time.
907 4. Fixed a memory leak which was causing dump to grow very big
908 (270MB when dumping a 10GB filesystem...). Thanks to Jason
909 Fearon <jasonf@netrider.org.au> for reporting the bug.
911 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
912 ======================================================================
914 1. Make configure test if the system glob routines support
915 extended syntax (ALTDIRFUNC). If not, use the internal glob
916 routines instead of system ones. Thanks to Bernhard Sadlowski
917 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
918 and helping me resolve this and other minor libc5 compiling
921 2. Fix a problem when dumping a ext2fs with the 'filetype'
922 feature enabled. Thanks to Patrick J. LoPresti
923 <patl@cag.lcs.mit.edu> for reporting the bug and to
924 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
926 3. Made the nodump flag work on directories. A directory which
927 has the nodump flag gets never dumped, regardless of its
930 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
931 which allows dump on an active ext3 filesystem. However, this
932 is a "quick and dirty" patch which enables backup of an ext3
933 filesystem through the ext2 compatibility (by ignoring the
934 NEEDS_RECOVERY bit). The journal file is not recognized and
935 it is dumped (it should not).
937 5. Test the superblock compatibility flags when dumping, in order
938 to be sure that we know how to deal with specific features.
940 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
941 ====================================================================
943 1. Use lchown instead of chown, fixing a possible security problem
944 when restoring symlinks (a malicious user could use this
945 to deliberately corrupt the ownership of important system files).
946 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
947 this and providing the patch.
949 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
950 ====================================================================
952 1. Put dump sources under CVS, added Id tags in all files so
953 one can use 'ident' on binary files.
955 2. Added the dump/restore version in the usage text so one can
956 easily verify the version he is using.
958 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
959 a va_start/va_end problem on linux-ppc (always call va_start
960 va_end in pairs each time we use a vararg function).
962 4. Added again the DT_* constants because old libc does not
963 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
964 for submitting the bug report.
966 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
967 this should enable dumping big (huge) filesystems.
969 6. Added the RSH environment variable in order to be able to
970 use a rsh replacement like ssh when doing remote backups (and
971 bypass the security limitations of rcmd). Now you can do remote
972 backups without being root (or making dump setuid root).
974 7. Modified again the way dumpdates works. For incremental dumps,
975 we need to read dumpdates even if we are not using 'u' option.
976 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
979 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
980 ===================================================================
982 1. Removed the 'k' flag from the restore 'about' text if kerberos
985 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
986 to them (fsetflags takes a char*, setflags an open fd!).
988 3. (f)setflags is called only if the flags aren't empty. If the
989 file is a special file, a warning is printed, because changing
990 flags implies opening the device. Normally, a special file
991 should not have any flag... (Debian bug #29775, patch provided
992 by Abhijit Dasgupta <abhijit@ans.net>).
994 4. Made possible to dump a file system not mentioned in /etc/fstab.
995 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
997 5. Changed the default behaviour to not create dumpdates
998 unless 'u' option is specified. Removed the old "debian-patch"
999 which provided the same thing. (Debian bug #38136, #33818).
1001 6. Removed all those dump*announce, since they were getting old...
1003 7. Added warning messages if dumpdates does not exist and
1004 when an inferior level dump does not exist (except for a level 0
1007 8. Debugged the glob calls in interactive mode: restore used a
1008 dirent struct which was different from the /usr/include/dirent.h
1009 one (this used to work, is it a glibc2 change?), so none of the
1010 compat glob (which used /usr/include/dirent.h) or the system glob
1011 worked. Restore use now the system dirent (and the system
1012 DT_* constants), which are compatible with BSD ones.
1014 9. Added a configure flag (--with-dumpdatespath) to specify
1015 the location of dumpdates file. By default, it is
1018 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1019 included the current date/version in man pages.
1021 11. Corrected the estimation of remaining time when
1022 the operator doesn't change the tapes quickly enough. This
1023 was an old bug, I thought I corrected it, and discovered
1024 that in fact it was corrected in two different places, so
1025 the results canceled each other...
1027 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1028 ===================================================================
1030 1. Integrated multiple patches from RedHat, Debian and SuSE:
1032 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1034 - several fixes in the man pages.
1035 - update the default tape device to /dev/st0.
1036 - many updates for Linux Alpha (byte ordering, size_t etc).
1038 - use environment variable for TMPDIR (instead of /tmp).
1039 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1040 - workaround egcs bug (RedHat bugs #4281 and #2989).
1041 - wire $(OPT) throughout Makefile's.
1043 2. Upgrade the dump revision to 1, making possible to dump filesystems
1044 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1046 3. Fix some compile warnings, prototype all functions.
1048 4. Use glibc err/glob instead of internal compatibility
1049 routines (only if available).
1051 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1052 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1054 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1055 ======================================================================
1057 1. Integrated the changes from FreeBSD-3.1-RELEASE
1058 (mostly bug fixes, buffer overruns, dump has now an "automatic
1059 tape length calculation" flag, dump/restore can use kerberos now
1060 (this is NOT tested), use environment variables for TAPE and
1063 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1065 3. Corrected a bug in restore when using 'C' option with multi-volumes
1066 tapes (files splited accros two tapes give "size changed" errors
1069 4. Corrected the long standing bug when dumping multiple tapes.
1070 This works for me, needs further testing.
1072 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1073 ====================================================================
1075 1. Dump now runs correctly on kernels 2.1.x
1076 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1078 Changes between versions 0.4b2 and 0.4b3
1079 ========================================
1081 1. Use realpath() if available
1083 2. Report statistics
1085 Changes between versions 0.4b1 and 0.4b2
1086 ========================================
1088 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1091 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1093 3. Fixed configure.in to correctly handle --enable-rmt
1095 Changes between versions 0.3 and 0.4b1
1096 ======================================
1098 1. Integrated the changes from 4.4BSD-Lite2
1100 2. Integrated the patches from Debian and Red Hat
1102 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1104 4. Changed dump to use the Ext2fs library to get block addresses. This
1105 should solve the endianness problem on SparcLinux.
1107 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1108 distribution's one) to use autoconf
1110 6. Fixed a few minor bugs
1112 Changes between versions 0.2e and 0.2f
1113 ======================================
1115 1. Added the creation of named pipes (fifos) in restore.
1117 2. Added the -N flag in the restore manual page.
1119 3. Added the file kernel.patch which contains the llseek() optimization
1120 patch for 1.2.x kernels.
1122 4. Fixed a bug in the restoration of symbolic links: owner and group were
1125 5. Integrated some changes from FreeBSD 2.2.
1127 6. Added a call to ftruncate() after restoring each file to restore
1128 correctly files ending by a hole.
1130 Changes between versions 0.2d and 0.2e
1131 ======================================
1133 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1134 with owner = root (0) and group = root/wheel/whatever (0).
1136 Changes between versions 0.2c and 0.2d
1137 ======================================
1139 1. Dump is now able to backup 2GB+ filesystems.
1141 2. Dump and restore can now be linked as static binaries.
1143 Changes between versions 0.2b and 0.2c
1144 ======================================
1146 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1148 Changes between versions 0.2a and 0.2b
1149 ======================================
1151 1. Really fixed the bug that I should have corrected in 0.2a.
1153 2. Enabled optimization again.
1155 Changes between versions 0.2 and 0.2a
1156 =====================================
1158 1. Disabled the optimization during compilation.
1160 Changes between versions 0.1 and 0.2
1161 ====================================
1163 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1164 the fs_type field (actually, I modified the file fstab.c to make it
1165 use the mntent functions).
1167 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1168 made by dump should be readable by the BSD restore and backups made
1169 by the BSD dump should be readable by restore. Unfortunately, this
1170 means that the dump format has changed between version 0.1 and version
1173 3. Dump is now able to backup a subtree, it is no longer limited to whole
1174 filesystems like the BSD version.
1176 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1179 Changes between versions 0.0 and 0.1
1180 ====================================
1182 1. Now create links rdump and rrestore during the `make install' step.
1184 2. Linux port specific bugs added to the manual pages
1186 3. Incorrect estimation of the number of tapes blocks fixed when doing
1187 incremental backups.
1189 4. Better ls-like format in restore in interactive mode.
