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 5. Fixed (again) handling of long (largefile) seeks in rmt.
24 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
27 6. Fixed restore corner case when dealing with large block sizes
28 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
29 <fabrice@bellet.info> for reporting the bug.
31 7. Fixed a bug preventing dump to access a filesystem having
32 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
33 for reporting the bug.
35 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
36 =======================================================================
38 1. Added a note in the restore man page clarifying the question
39 'set the permissions on the current directory ?' asked by
40 restore at the end of treatment in -i and -x modes.
42 2. Fixed the endianess issues when reading compressed tapes.
43 Thanks to Dark Force <daq4th@users.sourceforge.net> for
44 reporting this bug and providing test cases.
46 3. Fixed the "ACL won't be dumped" warning message (which showed
47 an extra, unrelated error message). Thanks to Dragan Krnic
48 <dkrnic@lycos.com> for reporting this bug.
50 4. Made dump look first into /etc/mtab, then into /etc/fstab
51 when searching for filesystem paths. Also fixed some problems
52 caused by binding mounts or multiple block device mounts.
53 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
54 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
55 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
56 and #160305, Sourceforge bugs #618699 and #679832).
58 5. Made dump's -I option accept the value '0' meaning all the
59 read errors will be ignored. This can be useful when running
60 dump from unattended sessions (like cron jobs). Thanks to
61 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
63 6. Fixed the output of dump to indicate 'blocks' instead of
64 'tape blocks' in the various messages (blocks are always
65 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
66 made it clearly print the current blocksize at the start of
67 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
70 7. Made rmt understand long (largefiles) seeks.
72 8. Fixed build with very old versions of libext2fs, where
73 EXT2_FT_* constants were undefined.
75 9. Made dump accept the dumpdates path on the command line
76 (-D file option) instead of using only the hardcoded one.
77 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
80 10. Enabled rmt, LFS, readline, QFA options by default in
81 ./configure. Updated the configure process (new versions
82 of config.guess, config.sub etc).
84 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
85 =======================================================================
87 1. Changed dump to use fcntl(F_SETLK) style locking instead
88 of flock() when locking the dumpdates file. With the old
89 locking scheme, a local user having read rights on the
90 dumpdates file could be able to do a Denial of Service attack
91 on dump. In order to lock the dumpdates file with the new
92 scheme, the user would need to have write access on the file.
93 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
94 reporting the bug (originally a bugtraq post).
96 2. Fixed interactive 'ls' which caused spurious errors warnings
97 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
98 <jorgen_ostling@users.sourceforge.net> for reporting this
101 3. Fixed dump's estimate when dealing with sparse inodes.
103 4. Modified dump to allow setting a blocksize bigger than 32kB
104 (raised the limit to 1024kB), because newer hardware needs
105 this for proper operation. Thanks to Dirk Traenapp
106 <dtraenapp@users.sourceforge.net> for reporting this.
108 5. Fixed a bug causing Dump to stop and report an error if an
109 inode number in the exclude file was followed by some amount
110 of whitespace. Thanks to Jeffrey Sofferin
111 <sofferin@users.sourceforge.net> for reporting this bug.
113 6. Fixed a bug which caused restore, in some particular cases,
114 to ask some 'scary' questions and leave a bunch of RSTTMP
115 directories behind when restoring incremental tapes. Thanks
116 to Philippe Troin <phil@fifi.org> for reporting this bug and
117 providing the test cases.
119 7. Changed the wording when inodes are excluded from dump:
120 replaced 'Added inode 7 to exclude list' with
121 'Excluding inode 7 (resize inode) from dump', as suggested
122 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
124 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
125 ===================================================================
127 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
128 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
129 <eros@lamel.bo.cnr.it> for reporting the bug.
131 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
132 ===================================================================
134 1. Made dump print out the ext2 logical block number in case of a read
135 error, which can be given as an argument to debugfs' ncheck command,
136 in order to find out the affected inode. Added note about this
137 usage in dump's man page.
139 2. Fixed a problem in restore when reading tapes written on big
140 endian machines with very old versions of dump. The patch was
141 contributed by George Helffrich <george@geology.bristol.ac.uk>.
143 3. Fixed the tape length calculation when using large tapes
144 and compression. Thanks to Georg Lippold
145 <g_lippold@sourceforge.net> for reporting the bug.
147 4. Added a new set of examples in dump_on_cd_2 directory, based
148 on dump_on_cd examples but somewhat enhanced, supporting DVD
149 media, and localized in english and german. Thanks to
150 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
152 5. Made dump save 32 bit UID/GID. Internally, this was achieved
153 by switching from the old BSD inode format to the new BSD
154 inode format, which means that the tape format was changed.
155 However, since all restore versions out there should
156 transparently support both inode formats, the change should
157 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
160 6. Fixed a lot of warnings in the code shown when compiling
161 with 'gcc -W'. Thanks to Matthias Andree
162 <matthias.andree@stud.uni-dortmund.de> for reporting this.
164 7. Fixed a small markup bug in the dump man page. Thanks to
165 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
168 8. Rewrote entirely the man pages using the tmac.an macro
169 package (Linux man page format) instead of the original BSD
170 format. They should be now cleaner and easier to modify.
172 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
173 ==================================================================
175 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
176 non Linux clients were misinterpreted. The description of the problem
177 (incompatible numbering in Linux mtio opcodes) is documented at
178 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
179 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
180 providing an excellent, cross-platform replacement for rmt in his
183 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
184 which caused restore to fail when the inode maps were not entirely
185 contained on the first volume (when using really small volumes or
186 when dumping a huge number of inodes).
188 3. Fixed a problem in dump, where files in subdirectories of directories
189 that have the nodump flag set (or being excluded with -e/-E) were
190 sometimes incorrectly dumped (instead of being excluded). The original
191 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
192 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
193 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
194 help testing the patch.
196 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
197 which makes one able to pipe the output of dump, by the net, to
198 a remote CD-burner server.
200 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
201 and use GNU's symbolic syntax over rmt instead of numerical values
202 to assure multiple platform compatibility.
204 6. Documented the -d option in restore.
206 7. Added a -v (verbose) mode to dump. For now it just prints the number
207 of the inode being dumped, but this could evolve in future versions
208 to include interesting debugging output.
210 8. Added a -o flag to restore, which automatically restores the current
211 directory permissions in -i or -x mode, without asking the operator
212 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
213 and Peter Samuel <peters@e-smith.com>.
215 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
216 ====================================================================
218 1. Fixed a bug in the QFA feature which could have caused
219 a bad tape positionning on restore (causing extra delays in
220 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
222 2. Added a small note in the dump man page specifying that
223 there should be no white space between the option letter and
224 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
226 3. Made restore work with older versions of the readline library,
227 by checking in configure for several extended symbols. Restore
228 can now be compiled with a readline as old as the 2.0 release
229 (though it may be a good idea to upgrade it to a more recent
230 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
231 reporting the build failures.
233 4. Fixed a performance problem with the QFA file creation in
234 dump, which made unnecessary seeks on the tape slowing down
235 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
236 reporting this issue.
238 5. Removed the inclusion of some kernel headers in the dump
239 source, which prevented the compile in some kernel/glibc
240 headers/architecture combination. Thanks to Bdale Garbee
241 <bdale@gag.com> for reporting the bug.
243 6. Added the appropriate error message when dump fails to
244 open the output file for writing. Thanks to Amith Varghese
245 <amithv@yahoo.com> for reporting this bug.
247 7. Made restore able to understand large Solaris ufsdump tapes
248 (containing inodes bigger than 4194304). Sun have introduced
249 an "extension" to the dump tape format when dealing with
250 those inodes, which was uncorrectly handled by Linux restore.
251 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
252 providing a test case.
254 8. Added the -m parameter to dump which optimises the output for
255 inodes having been changed but not modified since the last dump
256 ('changed' and 'modified' have the meaning defined in stat(2)).
257 For those inodes, dump will save only the metadata, instead of
258 saving the entire inode contents. Inodes which are either
259 directories or have been modified since the last dump are saved
260 in a regular way. Uses of this flag must be consistent, meaning
261 that either every dump in an incremental dump set have the flag,
264 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
265 =======================================================================
267 1. Fixed behaviour of dump when exceeding resource limits
270 2. Added the -L flag to restore to allow the user to specify a
271 maximal allowed number of miscompares when using restore
272 with the -C option to check the backup.
274 3. Detailed the manual entry for the -N option of restore.
276 4. Added the -a flag to restore to make able doing unattended
277 restores in -i or -x mode (automatically walks through the
278 multiple dump volumes).
280 5. Extended the QFA mode to work with local files and/or
281 remote tapes and files. This way, restore can know in advance
282 the tape number and the offset for the inodes to extract and
283 can minimize the extraction time by seeking directly to the
286 6. Added the -A <archive> option to both dump and restore,
287 which makes dump to archive a dump table-of-contents in
288 the specified file to be used by restore to determine
289 whether a file is in the dump file that is being restored.
290 (the archive file syntax is also compatible with the
291 Solaris ufsdump generated one).
293 7. Small fix in restore making it able to read some (broken ?)
294 Solaris ufsdump tapes.
296 8. Fixed dump to correctly recognise the root filesystem when using
297 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
298 for reporting this bug.
300 9. Added the -P <file> option to restore to create a
301 Quick File Access file from an already made dump. Patch
302 contributed by Uwe Gohlke <uwe@ugsoft.de>.
304 10. Made restore compile and run on Solaris, making it a
305 possible replacement for the standard ufsrestore. Port was
306 contributed by Uwe Gohlke <uwe@ugsoft.de>.
308 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
309 =====================================================================
311 1. Added a set of backup scripts from Eugenio Diaz
312 <getnito@yahoo.com> in the examples section. It features
313 automatic (cron based) full and incremental dumping of
314 several filesystems on a separate filesystem.
316 2. Fixed a off-by-one miscalculation which disabled dumping
317 a one letter subdirectory. Thanks to Chris Siebenmann
318 <cks@utcc.utoronto.ca> for reporting the bug.
320 3. Fixed several restore bugs occuring when trying to
321 restore some missing files on the tape. Thanks to Chris
322 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
324 4. Fixed --with-ldopts configure argument passing, installing from
325 a separate object directory, makefile cleanups contributed
326 by <splite@purdue.edu>.
328 5. Fix a bug which could caused, in some conditions, the highest
329 number inode of a filesystem, to not be dumped. Many thanks
330 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
333 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
334 =======================================================================
336 1. Added a mini howto from Patrick Walsh in the examples
339 2. Minor man pages syntax corrections. Thanks to
340 Chris Danis <screechco@home.com> for reporting the bugs.
342 3. Added a script from David B. Peterson <dave@toppledwagon.com>
343 to the examples section. It features dumping several
344 filesystems to a remote tape drive upon ssh.
346 4. Added a patch provided by Richard Jones <rich@annexia.org>
347 which allows BRADEMAX (number of read errors tolerated by
348 dump) to be adjusted using the -I option.
350 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
351 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
354 6. Add the -l option to restore to specify if, when doing a
355 remote restore, the file used to access the backup is a
356 regular file (the defaults being a tape drive). Restore needs
357 to know this information when reading a remote compressed
358 dump. Previously, this information was autodetected, but
359 the autodetection code fails (with ioctl: Inappropriate ioctl
360 for device) when using a non Linux remote box. Thanks to
361 many users and especially to Eros Albertazzi
362 <eros@lamel.bo.cnr.it> for reporting this.
364 7. Found a workaroung for the dump deadlock problem (3 childs
365 stuck in pause(), father in read()). The workaround seems
366 to work for me and several beta-testers. If it doesn't work
367 for you, please report back.
369 8. Updated the RPM spec file (BuildPrereq, URL etc).
371 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
372 ========================================================================
374 1. Fixed the permissions of a newly created QFA file by dump.
376 2. Cleaned up the source of dump (the external variables
377 definition was a complete mess, making possible to have
380 3. Fixed restore to use the full tape volume path when doing
381 a compare (since it changes the working directory to the
382 filesystem being compared in the process).
384 4. Added the -q option to dump which makes dump abort
385 whenever it needs operator attention. It should be
386 easier to use dump in scripts with this option.
388 5. Detect the use of incompatible options to dump and
389 refuse them (like -a and -B options together).
391 6. Added bzip2 compression to dump/restore (use option -j level
392 to select it). Note that you will need a restore version
393 >= 0.4b24 in order to restore a bzip2 compressed dump.
394 The same warning as for the zlib compression applies:
395 the tape format of a bzip2 dump is not compatible with the
396 original BSD tape format.
398 7. Fixed a overflow problem in dump corrupting the dump when
399 very large files were encountered. Thanks to Vladimir Nadvornik
402 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
403 kernel buffer/page cache before starting the dump, helping
404 a bit those who use dump on mounted filesystems. Thanks to
405 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
408 9. Updated the RPM spec file following the RedHat changes
409 (dynamically linked binaries now in /usr/sbin etc).
411 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
412 which enables restore to recognise multi volume compressed dumps
413 done on CD. Included his scripts for dump (which pipe the dump
414 output directly into cdrecord) and restore. There is now
415 possible to to backups to CD on the fly!
417 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
418 ===================================================================
420 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
421 Marcus Meissner (Caldera International Security Dept.).
423 2. Implement the Sun rmt extended protocol. Patch submitted
424 by Ian Gordon <iangordon@users.sourceforge.net>.
426 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
427 the linux kernel header. This ensures that dump always has the
428 latest version of this file. Patch submitted by
429 Andreas Dilger <adilger@turbolinux.com>.
431 4. Report any filesystem present in either /etc/fstab with a
432 positive passno or /etc/dumpdates in dump -w output.
433 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
435 5. Fixed the looping problem in dump introduced in the
438 6. Changed the -B option of dump to limit the size of
439 _compressed_ output per volume if compression is on.
440 Patch contributed by Helmut Jarausch
441 <jarausch@igpm.rwth-aachen.de>. Note however that, since
442 it is impossible to predict the size of the compressed
443 data before doing the compression, the -B limit is a bit
446 7. Fixed a bug in reading the operator typed file/tape path for
447 the next volume in restore.
449 8. Implemented a "-F script" option to restore which permits the
450 user to specify a script which will be launched at the
451 beginning of each tape, useful for automatic programming of
452 tape changers for example. See the restore man page for the
453 script parameters and return codes.
455 9. Small fix for the QFA routines provided by Uwe Gohlke
456 <uwe@ugsoft.de>, and some recommendations for QFA uses in
459 10. Fixed the multivolume restoring where making a mistake
460 to the 'Mount next tape' prompt caused several blocks to
463 11. Enhanced the -e option of dump to take as a parameter a
464 comma separated list of inode numbers.
466 12. Added the -E option to dump which specify a file containing
467 inode numbers to exclude from the dump.
469 13. Fixed the compressed multi-volume dump + restore.
471 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
472 ==================================================================
474 1. Made dump report the number of blocks dumped per volume.
475 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
477 2. Fix a bug in dump where waiting too much at the 'change volumes'
478 question caused the volume to be rewritten. Thanks to
479 Graham Reed <greed@users.sourceforge.net> for reporting the
480 bug and providing a patch.
482 3. Added a compression option to dump, contributed by Jerry
483 Peters <gapeters@worldnet.att.net>.
485 WARNING: the compression works only on files/pipes and
486 drives supporting variable block size.
488 WARNING2: tapes created using the compression feature are
489 incompatible with the standard dump tape format, and a
490 version of restore >= 0.4b22 will be needed for extraction.
492 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
493 architectures. Thanks to Paul Slootman <paul@debian.org> for
494 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
497 5. Many cleanups (CPP defines, const char warnings, check of
498 ext2fs COMPAT flags, time_t cleanups, added libext2 version
499 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
501 6. Made --prefix option work in configure. All the install path
502 are now based on the configure parameters.
504 7. Added the Quick File Access mode in dump/restore, contributed
505 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
506 a file tape position for each inode, and this file is used by
507 restore (if called with parameter Q and the filename)
508 to directly position the tape at the file restore is currently
509 working on. This saves hours when restoring single files from
510 large backups, saves the tapes and the drive's head. Use
511 --enable-qfa option of configure to compile in the QFA support.
513 8. Added the possibility to dump several files and directories
514 in a single invocation of dump. Thanks to Uwe Gohlke
515 <uwe@ugsoft.de> for implementing this option.
517 9. Fixed the dumping and restoring of files with holes
518 (files ending with holes didn't get dumped or restored
521 10. Fixed a socket descriptor leak in dump, which leaved opened
522 3 file descriptors per dump process (and there is one dump
525 11. Fixed dump large file system support, by explicit use of
526 open64/lseek64/etc functions (explicit use needed because
527 e2fsprogs libraries don't behave well when compiled with
528 FILE_OFFSET_BITS=64).
530 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
531 ======================================================================
533 1. Fixed some bugs in the dump -w|-W logic introduced by
534 the previous version. Thanks to Andreas Dilger
535 <adilger@turbolinux.com> for his help on this one.
537 2. Fixed again a compilation problem when using old e2fs
538 headers (filesystem label related). Thanks to many users
539 who reported this stupid error.
541 3. Fixed a build problem on old lib5 based systems dealing with
542 _PATH_MNTTAB being undefined. Thanks to John Adams
543 <johna@onevista.com> for reporting the bug.
545 4. Improved the error detection in restore when creating
546 the temporary files in TMPDIR. Now restore will corectly
547 report a 'no space left on device' error instead of
548 strange errors which could imply an archive corruption.
549 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
550 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
552 5. Added the throughput information in dump's progression
553 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
556 6. Use libext2fs's inode scanning routines, which are particularly
557 robust when dealing with errors (especially when having some
558 bad blocks on the filesystem). Many thanks to Colin
559 <colin@horizon.com> for reporting the bug, investigating
560 the issues, finding a workaround, writing the patch and
561 fully testing it... (of course, if this patch will break
562 anything, he is to blame for :-)).
564 7. Made dump and restore LFS aware. Dump can dump a filesystem
565 containing large files, generate a large file on output and
566 restore can restore them. This feature is not enabled by
567 default, use --enable-largefile option of configure to enable
568 it (you need to have a LFS aware glibc though). Thanks to
569 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
570 and to Theodore T'so <tytso@valinux.com> for his always
573 8. Made dump ask upon a tape write error if it should rewrite
574 the current volume (assume this is a bad tape) or if it should
575 assume an end-of-tape condition (useful for tape drives which
576 behaves badly at the end of the tape). Thanks to Andreas
577 Dilger <adilger@turbolinux.com> for the suggestion.
579 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
580 =======================================================================
582 1. Fixed a small compilation problem due to a change
583 in the definintion of the struct sigaction in
584 glibc 2.0 / libc5. Thanks to Gunther Schlegel
585 <schlegel@riege.de> for reporting the bug and to
586 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
589 2. Modified the label and uuid analysis in order to be
590 self-contained (independant of kernel/libc headers). This
591 should fix the compile with older kernel/libc headers and
592 will preserve the functionality. Thanks to Bernhard Erdmann
593 <bernhard.erdmann@gmx.de> for reporting the bug.
595 3. The 'exclude inode' option, if applied to a directory
596 inode, excludes now correctly all the leaves of this
597 directory. Thanks to John R. Dennison
598 <gerdesas@users.sourceforge.net> for reporting the bug.
600 4. Fixed the '-e' option to disable the possibility
601 to exclude the root inode (which causes the dumps to
602 be unreadable by restore). Prevented array overflow
603 when multiple -e options are used.
605 5. Fixed dump to correctly interpret a filesystem argument
606 which is a mountpoint and it is not an absolute path
607 (as specified in the fstab). Thanks to Bernhard R. Erdmann
608 <be@berdmann.de> for reporting the bug.
610 6. Made dump able to backup files larger than 2 GB. Note that
611 dump still doesn't cope with files larger than 4 GB.
613 7. Restore the real uid and gid before invoking an external
614 RSH program (big hole when dump or restore is suid root!).
616 8. Get the values for the default tape device and the location
617 of fstab file from the system headers. Thanks to
618 Andreas Dilger <adilger@turbolinux.com> for the patch.
620 9. Made dump -w|-W report all recognized filesystems
621 present in either /etc/fstab or /etc/dumpdates, and present
622 the list in the same order as in fstab file. Thanks
623 to Andreas Dilger <adilger@turbolinux.com> for the patch.
625 10. Made dump's -a (automatic end of tape detection) the
626 default. Specifying one of -B, -c, -d or -s options will
627 override the EOM detection. Thanks to Andreas Dilger
628 <adilger@turbolinux.com> for the patch.
630 11. Save the ext2 filesystem label into the dump volume label.
631 Specifying a volume label on the command line (-L option)
632 will override this feature. Thanks to Andreas Dilger
633 <adilger@turbolinux.com> for the patch.
635 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
636 =====================================================================
638 1. Fixed the signal handling in dump (which I broke in 0.4b17)
639 which was causing several strange dump failures (dump
640 hanged or segmentation faults etc).
642 2. Specified the default blocksize in the dump man page.
644 3. Changed two info messages of restore to be written on stdout
645 instead of stderr in order to leave stderr only for errors
646 or warnings. Thanks to Stephen Atwell
647 <satwell@urbana.css.mot.com> for the suggestion.
649 4. Corrected an off by one calculation which prevented
650 dumping a directory having a 1 character name length.
651 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
652 for reporting the bug.
654 5. Reinforce dump in order to allow only level 0 and no
655 -u option when dumping a subdirectory, and document
656 this in the man page. Thanks to Bernhard Erdmann
657 <bernhard.erdmann@gmx.de> for reporting the bug.
659 6. Fixed a small harmless bug in restore which caused
660 in some conditions hard links to be restored several
661 times (therefore generation some warning messages).
662 Thanks to Kenneth Porter <shiva@well.com> for
665 7. Updated the RPM spec file to the latest RedHat version,
666 providing FHS packaging and other cosmetic changes.
667 You will need RPM version >= 3.0.5 in order to build the RPM.
669 8. Updated the configure script to check for libtermcap
670 before checking for libreadline, because we need this
671 library in order to compile the readline support.
673 9. Made dump understand the LABEL= and UUID= notation
674 both in /etc/fstab and on the command line. Note that
675 you will need the /proc filesystem in order to use
676 these notations. Thanks to Erik Troan <ewt@redhat.com>
677 for providing the patch.
679 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
680 ===================================================================
682 1. Fixed a potential buffer overflow in restore. Thanks
683 to Stan Bubrouski <satan@fastdial.net> for reporting
686 2. Fixed a readline-related bug which prevented
687 'cat DUMPFILE | restore -i -f -' from working. Thanks
688 to Charles Karney <karney@users.sourceforge.net>
691 3. Changed a few "panic" into "exit", causing restore to
692 be more stable against some attacks (like the last one
693 reported on Bugtraq, although the last version of restore
694 was not vulnerable - just dumped core). Thanks to
695 Andreas Hasenack <andreas@conectiva.com.br> for reporting
698 4. Removed the suid-root bit on dump and restore in the
699 default build (and generated RPMs). It should be safer
700 now. Users who need the suid-root capabilities in order
701 to make network backups should read first the man page
702 of dump and enable the suid bit manually.
704 5. Added -ltermcap to the compile parameters for restore
705 when using readline support, in order to make the compile
706 process work on some systems (SuSE ?). Thanks to
707 Patrik Schindler <poc@pocnet.net> for reporting the bug.
709 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
710 ====================================================================
712 1. The -F script is called now *only* at the end of a tape,
713 not at the end of the dump. Thanks to Christian Haul
714 <haul@informatik.tu-darmstadt.de> for the bug report.
716 Normally, the device name and the current volume number
717 are passed on the command line of the script. However,
718 if you want the old style script (with no arguments
719 passed on the command line), you can enable it in
720 configure with the --enable-oldstylefscript.
722 2. Use posix signal handling to preserve dump functionality
723 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
726 3. Made the exit code of restore in case of a 'C'ompare
727 command reflect the result of the compare. An exit status
728 of 0 means the dump archive is correct, 1 means tape errors,
729 2 means that some files were modified. Thanks to Kenneth Porter
730 <shiva@well.com> for the suggestion.
732 4. Made (finally) quotes work in interactive restore.
734 5. Small fixes in order to allow dump to compile with a
735 really old e2fsprogs version. Thanks to Ian Zimmerman
736 <itz@speakeasy.org> for the bug report.
738 6. Add GNU readline capabilities to interactive restore.
739 Use configure's --enable-readline flag to enable this feature.
740 Thanks to Patrik Schindler <poc@pocnet.net> for the
743 7. Do the compare on the fly in restore 'C' mode (this will
744 allow not to exhaust the available /tmp space when
745 ccmparing large files). Thanks to Kenneth Porter
746 <shiva@well.com> for the suggestion.
748 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
749 ====================================================================
751 1. Fixed some several duplicate 'DUMP: DUMP:' in the
754 2. Corrected the estimation of blocks to dump. Note that
755 this is still wrong for large directory inodes, due
756 to the size of a BSD directory entry on the tape
757 (estimation is based on the size of the ext2 directory,
758 which is smaller because it doesn't contain the null
759 character at the end).
761 3. Made dump report the total number of MB written to
762 tape at the end of run. Thanks to W. Reilly Cooley
763 <wcooley@nakedape.cc> for the patch.
765 4. Added the -X option to restore giving the possibility
766 to read the names of the files to be extracted/listed
767 from a text file (in addition of the command line).
768 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
771 5. Added the device name and the current volume number
772 as arguments to the end of tape script (dump -F option).
774 6. Made the multi-volume dump work again (after having
775 broken it in 0.4b15).
777 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
778 ===================================================================
780 1. Added a prompt command in interactive restore mode. Thanks
781 to Andreas Dilger <adilger@home.com> for the patch.
783 2. Fixed a buffer overflow problem in dump (caused by
784 not checking the size of the filesystem parameter).
785 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
786 reporting this on Bugtraq (and to several dump users
787 who forwarded me his mail).
789 3. Added the '-F script' option to dump in order to
790 launch a script at the end of each tape (to be used
791 with a tape changer, or to notify the sysadmin by
794 4. Fixed a bug in restore compare code caused by the changes
797 5. Fixed the treatment of options using the old BSD syntax
798 in both dump and restore.
800 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
801 =======================================================================
803 1. Fixed a bug in dump which may have caused invalid deleted
804 directories to be dumped out if they were deleted after the
805 mapping pass. This could occure on active filesystem and lead
806 to heap corruption (causing dump malfunction in many possible ways).
807 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
808 bug and submitting the patch.
810 2. Fixed the handling of the filesystem parameter in dump. A
811 '/mnt/disk' parameter caused the disk contents to be dumped,
812 but a '/mnt/disk/' parameter caused the mountpoint directory
813 to be dumped (generally an empty directory).
815 3. Improved the output of dump in order to tell which directory
816 it is currently dumping (when dumping a subtree).
818 4. Added the '-e' exclude inode option to dump. Thanks to
819 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
821 5. Added a REPORTING-BUGS file in order to provide a guide
822 on how to correctly report a bug in dump/restore.
824 6. Fixed a restore problem when restoring a hard link to an inode
825 having the immutable or append-only attribute set. Thanks to
826 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
828 7. Fixed a compatibility problem between dumps made on little
829 endian machines (the format was correct) and big endian
830 machines (the format was incorrect). This fix break the
831 compatibility with the older dumps made on big endian
832 machines (sparc, m86k, ppc etc). For the first time in
833 linux dump's history (I believe), the dumps made by *BSD,
834 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
835 so interchangeable. Thanks to Rob Cermak
836 <cermak@ahab.rutgers.edu> for submitting the bug and
837 helping me test the fix.
839 8. Fixed the way dump reports the remaining percent/time, if
840 the number of blocks actually dumped exceeds the estimated
841 number of blocks. Thanks to Jean-Paul van der Jagt
842 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
844 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
845 ======================================================================
847 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
848 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
850 2. Removed the requirement to build the RPM as root from the
851 spec file. Thanks to Christian Weisgerber
852 <naddy@mips.rhein-neckar.de> for submitting this.
854 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
855 causing dump to block when dumping really huge filesystems.
856 Many thanks to Patrik Schindler <poc@pocnet.net> for
857 helping me find this bug.
859 4. Fixed the treatment for an interrupt signal when dump access
860 the remote tape through RSH. Thanks to Christian Weisgerber
861 <naddy@mips.rhein-neckar.de> for providing the patch.
863 5. Fixed a bug which was causing dump/restore to display
864 garbage characters instead of the remote host name.
866 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
867 =====================================================================
869 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
870 <kukuk@suse.de> for submitting the patch.
872 2. Fix for the exit code when using the size estimate option of
873 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
874 submitting the patch.
876 3. Handle EINTR in atomical reads/writes in dump, which was causing
877 dump to fail on some systems. Thanks to Eric Jergensen
878 <eric@dvns.com> for reporting the bug and submitting the patch.
880 4. Handle more than 16 characters for the device names in dumpdates.
881 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
882 tracking down the problem and proposing the solution.
884 5. Fixed a bug in dump which prevented the creation of the
885 dumpdates file when doing a 0-level dump without already
886 having a dumpdates file. Thanks to Patrik Schindler
887 <poc@pocnet.net> for reporting the bug.
889 6. Changed the way dump 'S' flag reports the size estimate
890 from number of blocks into bytes (making it compatible
891 with the Solaris version, and simplifying things for
892 amanda users). Thanks to Jason L Tibbitts III
893 <tibbs@math.uh.edu> for reporting the bug.
895 7. Fixed a compatibility problem in linux/alpha dump tape format.
896 Now the linux/alpha dump are (again) compatible with the
897 other dump formats. But this breaks compatibility with
898 older dumps made on alpha. Thanks to Mike Tibor
899 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
901 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
902 ======================================================================
904 1. Added a '--enable-kerberos' to configure.
906 2. Added a 'S' option to dump which determines the amount of space
907 that is needed to perform the dump without actually doing it, similar
908 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
909 <cermak@ahab.rutgers.edu>.
911 3. Added a 'M' multi-volume option to dump and restore which enables
912 dumping to multiple files (useful when dumping to an ext2
913 partition to make several dump files in order to bypass the 2GB
914 file size limitation). The 'f' argument is treated as a prefix and
915 the output files will be named <prefix>001, <prefix>002 etc. With
916 the 'M' flag, restore automatically selects the right file without
917 asking to enter a new tape each time.
919 4. Fixed a memory leak which was causing dump to grow very big
920 (270MB when dumping a 10GB filesystem...). Thanks to Jason
921 Fearon <jasonf@netrider.org.au> for reporting the bug.
923 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
924 ======================================================================
926 1. Make configure test if the system glob routines support
927 extended syntax (ALTDIRFUNC). If not, use the internal glob
928 routines instead of system ones. Thanks to Bernhard Sadlowski
929 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
930 and helping me resolve this and other minor libc5 compiling
933 2. Fix a problem when dumping a ext2fs with the 'filetype'
934 feature enabled. Thanks to Patrick J. LoPresti
935 <patl@cag.lcs.mit.edu> for reporting the bug and to
936 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
938 3. Made the nodump flag work on directories. A directory which
939 has the nodump flag gets never dumped, regardless of its
942 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
943 which allows dump on an active ext3 filesystem. However, this
944 is a "quick and dirty" patch which enables backup of an ext3
945 filesystem through the ext2 compatibility (by ignoring the
946 NEEDS_RECOVERY bit). The journal file is not recognized and
947 it is dumped (it should not).
949 5. Test the superblock compatibility flags when dumping, in order
950 to be sure that we know how to deal with specific features.
952 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
953 ====================================================================
955 1. Use lchown instead of chown, fixing a possible security problem
956 when restoring symlinks (a malicious user could use this
957 to deliberately corrupt the ownership of important system files).
958 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
959 this and providing the patch.
961 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
962 ====================================================================
964 1. Put dump sources under CVS, added Id tags in all files so
965 one can use 'ident' on binary files.
967 2. Added the dump/restore version in the usage text so one can
968 easily verify the version he is using.
970 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
971 a va_start/va_end problem on linux-ppc (always call va_start
972 va_end in pairs each time we use a vararg function).
974 4. Added again the DT_* constants because old libc does not
975 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
976 for submitting the bug report.
978 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
979 this should enable dumping big (huge) filesystems.
981 6. Added the RSH environment variable in order to be able to
982 use a rsh replacement like ssh when doing remote backups (and
983 bypass the security limitations of rcmd). Now you can do remote
984 backups without being root (or making dump setuid root).
986 7. Modified again the way dumpdates works. For incremental dumps,
987 we need to read dumpdates even if we are not using 'u' option.
988 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
991 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
992 ===================================================================
994 1. Removed the 'k' flag from the restore 'about' text if kerberos
997 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
998 to them (fsetflags takes a char*, setflags an open fd!).
1000 3. (f)setflags is called only if the flags aren't empty. If the
1001 file is a special file, a warning is printed, because changing
1002 flags implies opening the device. Normally, a special file
1003 should not have any flag... (Debian bug #29775, patch provided
1004 by Abhijit Dasgupta <abhijit@ans.net>).
1006 4. Made possible to dump a file system not mentioned in /etc/fstab.
1007 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1009 5. Changed the default behaviour to not create dumpdates
1010 unless 'u' option is specified. Removed the old "debian-patch"
1011 which provided the same thing. (Debian bug #38136, #33818).
1013 6. Removed all those dump*announce, since they were getting old...
1015 7. Added warning messages if dumpdates does not exist and
1016 when an inferior level dump does not exist (except for a level 0
1019 8. Debugged the glob calls in interactive mode: restore used a
1020 dirent struct which was different from the /usr/include/dirent.h
1021 one (this used to work, is it a glibc2 change?), so none of the
1022 compat glob (which used /usr/include/dirent.h) or the system glob
1023 worked. Restore use now the system dirent (and the system
1024 DT_* constants), which are compatible with BSD ones.
1026 9. Added a configure flag (--with-dumpdatespath) to specify
1027 the location of dumpdates file. By default, it is
1030 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1031 included the current date/version in man pages.
1033 11. Corrected the estimation of remaining time when
1034 the operator doesn't change the tapes quickly enough. This
1035 was an old bug, I thought I corrected it, and discovered
1036 that in fact it was corrected in two different places, so
1037 the results canceled each other...
1039 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1040 ===================================================================
1042 1. Integrated multiple patches from RedHat, Debian and SuSE:
1044 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1046 - several fixes in the man pages.
1047 - update the default tape device to /dev/st0.
1048 - many updates for Linux Alpha (byte ordering, size_t etc).
1050 - use environment variable for TMPDIR (instead of /tmp).
1051 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1052 - workaround egcs bug (RedHat bugs #4281 and #2989).
1053 - wire $(OPT) throughout Makefile's.
1055 2. Upgrade the dump revision to 1, making possible to dump filesystems
1056 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1058 3. Fix some compile warnings, prototype all functions.
1060 4. Use glibc err/glob instead of internal compatibility
1061 routines (only if available).
1063 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1064 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1066 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1067 ======================================================================
1069 1. Integrated the changes from FreeBSD-3.1-RELEASE
1070 (mostly bug fixes, buffer overruns, dump has now an "automatic
1071 tape length calculation" flag, dump/restore can use kerberos now
1072 (this is NOT tested), use environment variables for TAPE and
1075 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1077 3. Corrected a bug in restore when using 'C' option with multi-volumes
1078 tapes (files splited accros two tapes give "size changed" errors
1081 4. Corrected the long standing bug when dumping multiple tapes.
1082 This works for me, needs further testing.
1084 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1085 ====================================================================
1087 1. Dump now runs correctly on kernels 2.1.x
1088 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1090 Changes between versions 0.4b2 and 0.4b3
1091 ========================================
1093 1. Use realpath() if available
1095 2. Report statistics
1097 Changes between versions 0.4b1 and 0.4b2
1098 ========================================
1100 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1103 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1105 3. Fixed configure.in to correctly handle --enable-rmt
1107 Changes between versions 0.3 and 0.4b1
1108 ======================================
1110 1. Integrated the changes from 4.4BSD-Lite2
1112 2. Integrated the patches from Debian and Red Hat
1114 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1116 4. Changed dump to use the Ext2fs library to get block addresses. This
1117 should solve the endianness problem on SparcLinux.
1119 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1120 distribution's one) to use autoconf
1122 6. Fixed a few minor bugs
1124 Changes between versions 0.2e and 0.2f
1125 ======================================
1127 1. Added the creation of named pipes (fifos) in restore.
1129 2. Added the -N flag in the restore manual page.
1131 3. Added the file kernel.patch which contains the llseek() optimization
1132 patch for 1.2.x kernels.
1134 4. Fixed a bug in the restoration of symbolic links: owner and group were
1137 5. Integrated some changes from FreeBSD 2.2.
1139 6. Added a call to ftruncate() after restoring each file to restore
1140 correctly files ending by a hole.
1142 Changes between versions 0.2d and 0.2e
1143 ======================================
1145 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1146 with owner = root (0) and group = root/wheel/whatever (0).
1148 Changes between versions 0.2c and 0.2d
1149 ======================================
1151 1. Dump is now able to backup 2GB+ filesystems.
1153 2. Dump and restore can now be linked as static binaries.
1155 Changes between versions 0.2b and 0.2c
1156 ======================================
1158 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1160 Changes between versions 0.2a and 0.2b
1161 ======================================
1163 1. Really fixed the bug that I should have corrected in 0.2a.
1165 2. Enabled optimization again.
1167 Changes between versions 0.2 and 0.2a
1168 =====================================
1170 1. Disabled the optimization during compilation.
1172 Changes between versions 0.1 and 0.2
1173 ====================================
1175 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1176 the fs_type field (actually, I modified the file fstab.c to make it
1177 use the mntent functions).
1179 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1180 made by dump should be readable by the BSD restore and backups made
1181 by the BSD dump should be readable by restore. Unfortunately, this
1182 means that the dump format has changed between version 0.1 and version
1185 3. Dump is now able to backup a subtree, it is no longer limited to whole
1186 filesystems like the BSD version.
1188 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1191 Changes between versions 0.0 and 0.1
1192 ====================================
1194 1. Now create links rdump and rrestore during the `make install' step.
1196 2. Linux port specific bugs added to the manual pages
1198 3. Incorrect estimation of the number of tapes blocks fixed when doing
1199 incremental backups.
1201 4. Better ls-like format in restore in interactive mode.
