3 Changes between versions 0.4b29 and 0.4b30 (released ????????????????)
4 ======================================================================
6 1. Made dump print out the ext2 logical block number in case of a read
7 error, which can be given as an argument to debugfs' ncheck command,
8 in order to find out the affected inode. Added note about this
9 usage in dump's man page.
11 2. Fixed a problem in restore when reading tapes written on big
12 endian machines with very old versions of dump. The patch was
13 contributed by George Helffrich <george@geology.bristol.ac.uk>.
15 3. Fixed the tape length calculation when using large tapes
16 and compression. Thanks to Georg Lippold
17 <g_lippold@sourceforge.net> for reporting the bug.
19 4. Added a new set of examples in dump_on_cd_2 directory, based
20 on dump_on_cd examples but somewhat enhanced, supporting DVD
21 media, and localized in english and german. Thanks to
22 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
24 5. Made dump save 32 bit UID/GID. Internally, this was achieved
25 by switching from the old BSD inode format to the new BSD
26 inode format, which means that the tape format was changed.
27 However, since all restore versions out there should
28 transparently support both inode formats, the change should
29 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
32 6. Fixed a lot of warnings in the code shown when compiling
33 with 'gcc -W'. Thanks to Matthias Andree
34 <matthias.andree@stud.uni-dortmund.de> for reporting this.
36 7. Fixed a small markup bug in the dump man page. Thanks to
37 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
40 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
41 ==================================================================
43 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
44 non Linux clients were misinterpreted. The description of the problem
45 (incompatible numbering in Linux mtio opcodes) is documented at
46 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
47 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
48 providing an excellent, cross-platform replacement for rmt in his
51 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
52 which caused restore to fail when the inode maps were not entirely
53 contained on the first volume (when using really small volumes or
54 when dumping a huge number of inodes).
56 3. Fixed a problem in dump, where files in subdirectories of directories
57 that have the nodump flag set (or being excluded with -e/-E) were
58 sometimes incorrectly dumped (instead of being excluded). The original
59 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
60 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
61 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
62 help testing the patch.
64 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
65 which makes one able to pipe the output of dump, by the net, to
66 a remote CD-burner server.
68 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
69 and use GNU's symbolic syntax over rmt instead of numerical values
70 to assure multiple platform compatibility.
72 6. Documented the -d option in restore.
74 7. Added a -v (verbose) mode to dump. For now it just prints the number
75 of the inode being dumped, but this could evolve in future versions
76 to include interesting debugging output.
78 8. Added a -o flag to restore, which automatically restores the current
79 directory permissions in -i or -x mode, without asking the operator
80 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
81 and Peter Samuel <peters@e-smith.com>.
83 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
84 ====================================================================
86 1. Fixed a bug in the QFA feature which could have caused
87 a bad tape positionning on restore (causing extra delays in
88 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
90 2. Added a small note in the dump man page specifying that
91 there should be no white space between the option letter and
92 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
94 3. Made restore work with older versions of the readline library,
95 by checking in configure for several extended symbols. Restore
96 can now be compiled with a readline as old as the 2.0 release
97 (though it may be a good idea to upgrade it to a more recent
98 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
99 reporting the build failures.
101 4. Fixed a performance problem with the QFA file creation in
102 dump, which made unnecessary seeks on the tape slowing down
103 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
104 reporting this issue.
106 5. Removed the inclusion of some kernel headers in the dump
107 source, which prevented the compile in some kernel/glibc
108 headers/architecture combination. Thanks to Bdale Garbee
109 <bdale@gag.com> for reporting the bug.
111 6. Added the appropriate error message when dump fails to
112 open the output file for writing. Thanks to Amith Varghese
113 <amithv@yahoo.com> for reporting this bug.
115 7. Made restore able to understand large Solaris ufsdump tapes
116 (containing inodes bigger than 4194304). Sun have introduced
117 an "extension" to the dump tape format when dealing with
118 those inodes, which was uncorrectly handled by Linux restore.
119 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
120 providing a test case.
122 8. Added the -m parameter to dump which optimises the output for
123 inodes having been changed but not modified since the last dump
124 ('changed' and 'modified' have the meaning defined in stat(2)).
125 For those inodes, dump will save only the metadata, instead of
126 saving the entire inode contents. Inodes which are either
127 directories or have been modified since the last dump are saved
128 in a regular way. Uses of this flag must be consistent, meaning
129 that either every dump in an incremental dump set have the flag,
132 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
133 =======================================================================
135 1. Fixed behaviour of dump when exceeding resource limits
138 2. Added the -L flag to restore to allow the user to specify a
139 maximal allowed number of miscompares when using restore
140 with the -C option to check the backup.
142 3. Detailed the manual entry for the -N option of restore.
144 4. Added the -a flag to restore to make able doing unattended
145 restores in -i or -x mode (automatically walks through the
146 multiple dump volumes).
148 5. Extended the QFA mode to work with local files and/or
149 remote tapes and files. This way, restore can know in advance
150 the tape number and the offset for the inodes to extract and
151 can minimize the extraction time by seeking directly to the
154 6. Added the -A <archive> option to both dump and restore,
155 which makes dump to archive a dump table-of-contents in
156 the specified file to be used by restore to determine
157 whether a file is in the dump file that is being restored.
158 (the archive file syntax is also compatible with the
159 Solaris ufsdump generated one).
161 7. Small fix in restore making it able to read some (broken ?)
162 Solaris ufsdump tapes.
164 8. Fixed dump to correctly recognise the root filesystem when using
165 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
166 for reporting this bug.
168 9. Added the -P <file> option to restore to create a
169 Quick File Access file from an already made dump. Patch
170 contributed by Uwe Gohlke <uwe@ugsoft.de>.
172 10. Made restore compile and run on Solaris, making it a
173 possible replacement for the standard ufsrestore. Port was
174 contributed by Uwe Gohlke <uwe@ugsoft.de>.
176 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
177 =====================================================================
179 1. Added a set of backup scripts from Eugenio Diaz
180 <getnito@yahoo.com> in the examples section. It features
181 automatic (cron based) full and incremental dumping of
182 several filesystems on a separate filesystem.
184 2. Fixed a off-by-one miscalculation which disabled dumping
185 a one letter subdirectory. Thanks to Chris Siebenmann
186 <cks@utcc.utoronto.ca> for reporting the bug.
188 3. Fixed several restore bugs occuring when trying to
189 restore some missing files on the tape. Thanks to Chris
190 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
192 4. Fixed --with-ldopts configure argument passing, installing from
193 a separate object directory, makefile cleanups contributed
194 by <splite@purdue.edu>.
196 5. Fix a bug which could caused, in some conditions, the highest
197 number inode of a filesystem, to not be dumped. Many thanks
198 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
201 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
202 =======================================================================
204 1. Added a mini howto from Patrick Walsh in the examples
207 2. Minor man pages syntax corrections. Thanks to
208 Chris Danis <screechco@home.com> for reporting the bugs.
210 3. Added a script from David B. Peterson <dave@toppledwagon.com>
211 to the examples section. It features dumping several
212 filesystems to a remote tape drive upon ssh.
214 4. Added a patch provided by Richard Jones <rich@annexia.org>
215 which allows BRADEMAX (number of read errors tolerated by
216 dump) to be adjusted using the -I option.
218 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
219 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
222 6. Add the -l option to restore to specify if, when doing a
223 remote restore, the file used to access the backup is a
224 regular file (the defaults being a tape drive). Restore needs
225 to know this information when reading a remote compressed
226 dump. Previously, this information was autodetected, but
227 the autodetection code fails (with ioctl: Inappropriate ioctl
228 for device) when using a non Linux remote box. Thanks to
229 many users and especially to Eros Albertazzi
230 <eros@lamel.bo.cnr.it> for reporting this.
232 7. Found a workaroung for the dump deadlock problem (3 childs
233 stuck in pause(), father in read()). The workaround seems
234 to work for me and several beta-testers. If it doesn't work
235 for you, please report back.
237 8. Updated the RPM spec file (BuildPrereq, URL etc).
239 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
240 ========================================================================
242 1. Fixed the permissions of a newly created QFA file by dump.
244 2. Cleaned up the source of dump (the external variables
245 definition was a complete mess, making possible to have
248 3. Fixed restore to use the full tape volume path when doing
249 a compare (since it changes the working directory to the
250 filesystem being compared in the process).
252 4. Added the -q option to dump which makes dump abort
253 whenever it needs operator attention. It should be
254 easier to use dump in scripts with this option.
256 5. Detect the use of incompatible options to dump and
257 refuse them (like -a and -B options together).
259 6. Added bzip2 compression to dump/restore (use option -j level
260 to select it). Note that you will need a restore version
261 >= 0.4b24 in order to restore a bzip2 compressed dump.
262 The same warning as for the zlib compression applies:
263 the tape format of a bzip2 dump is not compatible with the
264 original BSD tape format.
266 7. Fixed a overflow problem in dump corrupting the dump when
267 very large files were encountered. Thanks to Vladimir Nadvornik
270 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
271 kernel buffer/page cache before starting the dump, helping
272 a bit those who use dump on mounted filesystems. Thanks to
273 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
276 9. Updated the RPM spec file following the RedHat changes
277 (dynamically linked binaries now in /usr/sbin etc).
279 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
280 which enables restore to recognise multi volume compressed dumps
281 done on CD. Included his scripts for dump (which pipe the dump
282 output directly into cdrecord) and restore. There is now
283 possible to to backups to CD on the fly!
285 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
286 ===================================================================
288 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
289 Marcus Meissner (Caldera International Security Dept.).
291 2. Implement the Sun rmt extended protocol. Patch submitted
292 by Ian Gordon <iangordon@users.sourceforge.net>.
294 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
295 the linux kernel header. This ensures that dump always has the
296 latest version of this file. Patch submitted by
297 Andreas Dilger <adilger@turbolinux.com>.
299 4. Report any filesystem present in either /etc/fstab with a
300 positive passno or /etc/dumpdates in dump -w output.
301 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
303 5. Fixed the looping problem in dump introduced in the
306 6. Changed the -B option of dump to limit the size of
307 _compressed_ output per volume if compression is on.
308 Patch contributed by Helmut Jarausch
309 <jarausch@igpm.rwth-aachen.de>. Note however that, since
310 it is impossible to predict the size of the compressed
311 data before doing the compression, the -B limit is a bit
314 7. Fixed a bug in reading the operator typed file/tape path for
315 the next volume in restore.
317 8. Implemented a "-F script" option to restore which permits the
318 user to specify a script which will be launched at the
319 beginning of each tape, useful for automatic programming of
320 tape changers for example. See the restore man page for the
321 script parameters and return codes.
323 9. Small fix for the QFA routines provided by Uwe Gohlke
324 <uwe@ugsoft.de>, and some recommendations for QFA uses in
327 10. Fixed the multivolume restoring where making a mistake
328 to the 'Mount next tape' prompt caused several blocks to
331 11. Enhanced the -e option of dump to take as a parameter a
332 comma separated list of inode numbers.
334 12. Added the -E option to dump which specify a file containing
335 inode numbers to exclude from the dump.
337 13. Fixed the compressed multi-volume dump + restore.
339 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
340 ==================================================================
342 1. Made dump report the number of blocks dumped per volume.
343 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
345 2. Fix a bug in dump where waiting too much at the 'change volumes'
346 question caused the volume to be rewritten. Thanks to
347 Graham Reed <greed@users.sourceforge.net> for reporting the
348 bug and providing a patch.
350 3. Added a compression option to dump, contributed by Jerry
351 Peters <gapeters@worldnet.att.net>.
353 WARNING: the compression works only on files/pipes and
354 drives supporting variable block size.
356 WARNING2: tapes created using the compression feature are
357 incompatible with the standard dump tape format, and a
358 version of restore >= 0.4b22 will be needed for extraction.
360 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
361 architectures. Thanks to Paul Slootman <paul@debian.org> for
362 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
365 5. Many cleanups (CPP defines, const char warnings, check of
366 ext2fs COMPAT flags, time_t cleanups, added libext2 version
367 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
369 6. Made --prefix option work in configure. All the install path
370 are now based on the configure parameters.
372 7. Added the Quick File Access mode in dump/restore, contributed
373 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
374 a file tape position for each inode, and this file is used by
375 restore (if called with parameter Q and the filename)
376 to directly position the tape at the file restore is currently
377 working on. This saves hours when restoring single files from
378 large backups, saves the tapes and the drive's head. Use
379 --enable-qfa option of configure to compile in the QFA support.
381 8. Added the possibility to dump several files and directories
382 in a single invocation of dump. Thanks to Uwe Gohlke
383 <uwe@ugsoft.de> for implementing this option.
385 9. Fixed the dumping and restoring of files with holes
386 (files ending with holes didn't get dumped or restored
389 10. Fixed a socket descriptor leak in dump, which leaved opened
390 3 file descriptors per dump process (and there is one dump
393 11. Fixed dump large file system support, by explicit use of
394 open64/lseek64/etc functions (explicit use needed because
395 e2fsprogs libraries don't behave well when compiled with
396 FILE_OFFSET_BITS=64).
398 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
399 ======================================================================
401 1. Fixed some bugs in the dump -w|-W logic introduced by
402 the previous version. Thanks to Andreas Dilger
403 <adilger@turbolinux.com> for his help on this one.
405 2. Fixed again a compilation problem when using old e2fs
406 headers (filesystem label related). Thanks to many users
407 who reported this stupid error.
409 3. Fixed a build problem on old lib5 based systems dealing with
410 _PATH_MNTTAB being undefined. Thanks to John Adams
411 <johna@onevista.com> for reporting the bug.
413 4. Improved the error detection in restore when creating
414 the temporary files in TMPDIR. Now restore will corectly
415 report a 'no space left on device' error instead of
416 strange errors which could imply an archive corruption.
417 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
418 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
420 5. Added the throughput information in dump's progression
421 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
424 6. Use libext2fs's inode scanning routines, which are particularly
425 robust when dealing with errors (especially when having some
426 bad blocks on the filesystem). Many thanks to Colin
427 <colin@horizon.com> for reporting the bug, investigating
428 the issues, finding a workaround, writing the patch and
429 fully testing it... (of course, if this patch will break
430 anything, he is to blame for :-)).
432 7. Made dump and restore LFS aware. Dump can dump a filesystem
433 containing large files, generate a large file on output and
434 restore can restore them. This feature is not enabled by
435 default, use --enable-largefile option of configure to enable
436 it (you need to have a LFS aware glibc though). Thanks to
437 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
438 and to Theodore T'so <tytso@valinux.com> for his always
441 8. Made dump ask upon a tape write error if it should rewrite
442 the current volume (assume this is a bad tape) or if it should
443 assume an end-of-tape condition (useful for tape drives which
444 behaves badly at the end of the tape). Thanks to Andreas
445 Dilger <adilger@turbolinux.com> for the suggestion.
447 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
448 =======================================================================
450 1. Fixed a small compilation problem due to a change
451 in the definintion of the struct sigaction in
452 glibc 2.0 / libc5. Thanks to Gunther Schlegel
453 <schlegel@riege.de> for reporting the bug and to
454 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
457 2. Modified the label and uuid analysis in order to be
458 self-contained (independant of kernel/libc headers). This
459 should fix the compile with older kernel/libc headers and
460 will preserve the functionality. Thanks to Bernhard Erdmann
461 <bernhard.erdmann@gmx.de> for reporting the bug.
463 3. The 'exclude inode' option, if applied to a directory
464 inode, excludes now correctly all the leaves of this
465 directory. Thanks to John R. Dennison
466 <gerdesas@users.sourceforge.net> for reporting the bug.
468 4. Fixed the '-e' option to disable the possibility
469 to exclude the root inode (which causes the dumps to
470 be unreadable by restore). Prevented array overflow
471 when multiple -e options are used.
473 5. Fixed dump to correctly interpret a filesystem argument
474 which is a mountpoint and it is not an absolute path
475 (as specified in the fstab). Thanks to Bernhard R. Erdmann
476 <be@berdmann.de> for reporting the bug.
478 6. Made dump able to backup files larger than 2 GB. Note that
479 dump still doesn't cope with files larger than 4 GB.
481 7. Restore the real uid and gid before invoking an external
482 RSH program (big hole when dump or restore is suid root!).
484 8. Get the values for the default tape device and the location
485 of fstab file from the system headers. Thanks to
486 Andreas Dilger <adilger@turbolinux.com> for the patch.
488 9. Made dump -w|-W report all recognized filesystems
489 present in either /etc/fstab or /etc/dumpdates, and present
490 the list in the same order as in fstab file. Thanks
491 to Andreas Dilger <adilger@turbolinux.com> for the patch.
493 10. Made dump's -a (automatic end of tape detection) the
494 default. Specifying one of -B, -c, -d or -s options will
495 override the EOM detection. Thanks to Andreas Dilger
496 <adilger@turbolinux.com> for the patch.
498 11. Save the ext2 filesystem label into the dump volume label.
499 Specifying a volume label on the command line (-L option)
500 will override this feature. Thanks to Andreas Dilger
501 <adilger@turbolinux.com> for the patch.
503 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
504 =====================================================================
506 1. Fixed the signal handling in dump (which I broke in 0.4b17)
507 which was causing several strange dump failures (dump
508 hanged or segmentation faults etc).
510 2. Specified the default blocksize in the dump man page.
512 3. Changed two info messages of restore to be written on stdout
513 instead of stderr in order to leave stderr only for errors
514 or warnings. Thanks to Stephen Atwell
515 <satwell@urbana.css.mot.com> for the suggestion.
517 4. Corrected an off by one calculation which prevented
518 dumping a directory having a 1 character name length.
519 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
520 for reporting the bug.
522 5. Reinforce dump in order to allow only level 0 and no
523 -u option when dumping a subdirectory, and document
524 this in the man page. Thanks to Bernhard Erdmann
525 <bernhard.erdmann@gmx.de> for reporting the bug.
527 6. Fixed a small harmless bug in restore which caused
528 in some conditions hard links to be restored several
529 times (therefore generation some warning messages).
530 Thanks to Kenneth Porter <shiva@well.com> for
533 7. Updated the RPM spec file to the latest RedHat version,
534 providing FHS packaging and other cosmetic changes.
535 You will need RPM version >= 3.0.5 in order to build the RPM.
537 8. Updated the configure script to check for libtermcap
538 before checking for libreadline, because we need this
539 library in order to compile the readline support.
541 9. Made dump understand the LABEL= and UUID= notation
542 both in /etc/fstab and on the command line. Note that
543 you will need the /proc filesystem in order to use
544 these notations. Thanks to Erik Troan <ewt@redhat.com>
545 for providing the patch.
547 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
548 ===================================================================
550 1. Fixed a potential buffer overflow in restore. Thanks
551 to Stan Bubrouski <satan@fastdial.net> for reporting
554 2. Fixed a readline-related bug which prevented
555 'cat DUMPFILE | restore -i -f -' from working. Thanks
556 to Charles Karney <karney@users.sourceforge.net>
559 3. Changed a few "panic" into "exit", causing restore to
560 be more stable against some attacks (like the last one
561 reported on Bugtraq, although the last version of restore
562 was not vulnerable - just dumped core). Thanks to
563 Andreas Hasenack <andreas@conectiva.com.br> for reporting
566 4. Removed the suid-root bit on dump and restore in the
567 default build (and generated RPMs). It should be safer
568 now. Users who need the suid-root capabilities in order
569 to make network backups should read first the man page
570 of dump and enable the suid bit manually.
572 5. Added -ltermcap to the compile parameters for restore
573 when using readline support, in order to make the compile
574 process work on some systems (SuSE ?). Thanks to
575 Patrik Schindler <poc@pocnet.net> for reporting the bug.
577 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
578 ====================================================================
580 1. The -F script is called now *only* at the end of a tape,
581 not at the end of the dump. Thanks to Christian Haul
582 <haul@informatik.tu-darmstadt.de> for the bug report.
584 Normally, the device name and the current volume number
585 are passed on the command line of the script. However,
586 if you want the old style script (with no arguments
587 passed on the command line), you can enable it in
588 configure with the --enable-oldstylefscript.
590 2. Use posix signal handling to preserve dump functionality
591 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
594 3. Made the exit code of restore in case of a 'C'ompare
595 command reflect the result of the compare. An exit status
596 of 0 means the dump archive is correct, 1 means tape errors,
597 2 means that some files were modified. Thanks to Kenneth Porter
598 <shiva@well.com> for the suggestion.
600 4. Made (finally) quotes work in interactive restore.
602 5. Small fixes in order to allow dump to compile with a
603 really old e2fsprogs version. Thanks to Ian Zimmerman
604 <itz@speakeasy.org> for the bug report.
606 6. Add GNU readline capabilities to interactive restore.
607 Use configure's --enable-readline flag to enable this feature.
608 Thanks to Patrik Schindler <poc@pocnet.net> for the
611 7. Do the compare on the fly in restore 'C' mode (this will
612 allow not to exhaust the available /tmp space when
613 ccmparing large files). Thanks to Kenneth Porter
614 <shiva@well.com> for the suggestion.
616 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
617 ====================================================================
619 1. Fixed some several duplicate 'DUMP: DUMP:' in the
622 2. Corrected the estimation of blocks to dump. Note that
623 this is still wrong for large directory inodes, due
624 to the size of a BSD directory entry on the tape
625 (estimation is based on the size of the ext2 directory,
626 which is smaller because it doesn't contain the null
627 character at the end).
629 3. Made dump report the total number of MB written to
630 tape at the end of run. Thanks to W. Reilly Cooley
631 <wcooley@nakedape.cc> for the patch.
633 4. Added the -X option to restore giving the possibility
634 to read the names of the files to be extracted/listed
635 from a text file (in addition of the command line).
636 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
639 5. Added the device name and the current volume number
640 as arguments to the end of tape script (dump -F option).
642 6. Made the multi-volume dump work again (after having
643 broken it in 0.4b15).
645 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
646 ===================================================================
648 1. Added a prompt command in interactive restore mode. Thanks
649 to Andreas Dilger <adilger@home.com> for the patch.
651 2. Fixed a buffer overflow problem in dump (caused by
652 not checking the size of the filesystem parameter).
653 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
654 reporting this on Bugtraq (and to several dump users
655 who forwarded me his mail).
657 3. Added the '-F script' option to dump in order to
658 launch a script at the end of each tape (to be used
659 with a tape changer, or to notify the sysadmin by
662 4. Fixed a bug in restore compare code caused by the changes
665 5. Fixed the treatment of options using the old BSD syntax
666 in both dump and restore.
668 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
669 =======================================================================
671 1. Fixed a bug in dump which may have caused invalid deleted
672 directories to be dumped out if they were deleted after the
673 mapping pass. This could occure on active filesystem and lead
674 to heap corruption (causing dump malfunction in many possible ways).
675 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
676 bug and submitting the patch.
678 2. Fixed the handling of the filesystem parameter in dump. A
679 '/mnt/disk' parameter caused the disk contents to be dumped,
680 but a '/mnt/disk/' parameter caused the mountpoint directory
681 to be dumped (generally an empty directory).
683 3. Improved the output of dump in order to tell which directory
684 it is currently dumping (when dumping a subtree).
686 4. Added the '-e' exclude inode option to dump. Thanks to
687 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
689 5. Added a REPORTING-BUGS file in order to provide a guide
690 on how to correctly report a bug in dump/restore.
692 6. Fixed a restore problem when restoring a hard link to an inode
693 having the immutable or append-only attribute set. Thanks to
694 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
696 7. Fixed a compatibility problem between dumps made on little
697 endian machines (the format was correct) and big endian
698 machines (the format was incorrect). This fix break the
699 compatibility with the older dumps made on big endian
700 machines (sparc, m86k, ppc etc). For the first time in
701 linux dump's history (I believe), the dumps made by *BSD,
702 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
703 so interchangeable. Thanks to Rob Cermak
704 <cermak@ahab.rutgers.edu> for submitting the bug and
705 helping me test the fix.
707 8. Fixed the way dump reports the remaining percent/time, if
708 the number of blocks actually dumped exceeds the estimated
709 number of blocks. Thanks to Jean-Paul van der Jagt
710 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
712 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
713 ======================================================================
715 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
716 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
718 2. Removed the requirement to build the RPM as root from the
719 spec file. Thanks to Christian Weisgerber
720 <naddy@mips.rhein-neckar.de> for submitting this.
722 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
723 causing dump to block when dumping really huge filesystems.
724 Many thanks to Patrik Schindler <poc@pocnet.net> for
725 helping me find this bug.
727 4. Fixed the treatment for an interrupt signal when dump access
728 the remote tape through RSH. Thanks to Christian Weisgerber
729 <naddy@mips.rhein-neckar.de> for providing the patch.
731 5. Fixed a bug which was causing dump/restore to display
732 garbage characters instead of the remote host name.
734 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
735 =====================================================================
737 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
738 <kukuk@suse.de> for submitting the patch.
740 2. Fix for the exit code when using the size estimate option of
741 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
742 submitting the patch.
744 3. Handle EINTR in atomical reads/writes in dump, which was causing
745 dump to fail on some systems. Thanks to Eric Jergensen
746 <eric@dvns.com> for reporting the bug and submitting the patch.
748 4. Handle more than 16 characters for the device names in dumpdates.
749 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
750 tracking down the problem and proposing the solution.
752 5. Fixed a bug in dump which prevented the creation of the
753 dumpdates file when doing a 0-level dump without already
754 having a dumpdates file. Thanks to Patrik Schindler
755 <poc@pocnet.net> for reporting the bug.
757 6. Changed the way dump 'S' flag reports the size estimate
758 from number of blocks into bytes (making it compatible
759 with the Solaris version, and simplifying things for
760 amanda users). Thanks to Jason L Tibbitts III
761 <tibbs@math.uh.edu> for reporting the bug.
763 7. Fixed a compatibility problem in linux/alpha dump tape format.
764 Now the linux/alpha dump are (again) compatible with the
765 other dump formats. But this breaks compatibility with
766 older dumps made on alpha. Thanks to Mike Tibor
767 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
769 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
770 ======================================================================
772 1. Added a '--enable-kerberos' to configure.
774 2. Added a 'S' option to dump which determines the amount of space
775 that is needed to perform the dump without actually doing it, similar
776 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
777 <cermak@ahab.rutgers.edu>.
779 3. Added a 'M' multi-volume option to dump and restore which enables
780 dumping to multiple files (useful when dumping to an ext2
781 partition to make several dump files in order to bypass the 2GB
782 file size limitation). The 'f' argument is treated as a prefix and
783 the output files will be named <prefix>001, <prefix>002 etc. With
784 the 'M' flag, restore automatically selects the right file without
785 asking to enter a new tape each time.
787 4. Fixed a memory leak which was causing dump to grow very big
788 (270MB when dumping a 10GB filesystem...). Thanks to Jason
789 Fearon <jasonf@netrider.org.au> for reporting the bug.
791 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
792 ======================================================================
794 1. Make configure test if the system glob routines support
795 extended syntax (ALTDIRFUNC). If not, use the internal glob
796 routines instead of system ones. Thanks to Bernhard Sadlowski
797 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
798 and helping me resolve this and other minor libc5 compiling
801 2. Fix a problem when dumping a ext2fs with the 'filetype'
802 feature enabled. Thanks to Patrick J. LoPresti
803 <patl@cag.lcs.mit.edu> for reporting the bug and to
804 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
806 3. Made the nodump flag work on directories. A directory which
807 has the nodump flag gets never dumped, regardless of its
810 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
811 which allows dump on an active ext3 filesystem. However, this
812 is a "quick and dirty" patch which enables backup of an ext3
813 filesystem through the ext2 compatibility (by ignoring the
814 NEEDS_RECOVERY bit). The journal file is not recognized and
815 it is dumped (it should not).
817 5. Test the superblock compatibility flags when dumping, in order
818 to be sure that we know how to deal with specific features.
820 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
821 ====================================================================
823 1. Use lchown instead of chown, fixing a possible security problem
824 when restoring symlinks (a malicious user could use this
825 to deliberately corrupt the ownership of important system files).
826 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
827 this and providing the patch.
829 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
830 ====================================================================
832 1. Put dump sources under CVS, added Id tags in all files so
833 one can use 'ident' on binary files.
835 2. Added the dump/restore version in the usage text so one can
836 easily verify the version he is using.
838 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
839 a va_start/va_end problem on linux-ppc (always call va_start
840 va_end in pairs each time we use a vararg function).
842 4. Added again the DT_* constants because old libc does not
843 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
844 for submitting the bug report.
846 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
847 this should enable dumping big (huge) filesystems.
849 6. Added the RSH environment variable in order to be able to
850 use a rsh replacement like ssh when doing remote backups (and
851 bypass the security limitations of rcmd). Now you can do remote
852 backups without being root (or making dump setuid root).
854 7. Modified again the way dumpdates works. For incremental dumps,
855 we need to read dumpdates even if we are not using 'u' option.
856 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
859 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
860 ===================================================================
862 1. Removed the 'k' flag from the restore 'about' text if kerberos
865 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
866 to them (fsetflags takes a char*, setflags an open fd!).
868 3. (f)setflags is called only if the flags aren't empty. If the
869 file is a special file, a warning is printed, because changing
870 flags implies opening the device. Normally, a special file
871 should not have any flag... (Debian bug #29775, patch provided
872 by Abhijit Dasgupta <abhijit@ans.net>).
874 4. Made possible to dump a file system not mentioned in /etc/fstab.
875 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
877 5. Changed the default behaviour to not create dumpdates
878 unless 'u' option is specified. Removed the old "debian-patch"
879 which provided the same thing. (Debian bug #38136, #33818).
881 6. Removed all those dump*announce, since they were getting old...
883 7. Added warning messages if dumpdates does not exist and
884 when an inferior level dump does not exist (except for a level 0
887 8. Debugged the glob calls in interactive mode: restore used a
888 dirent struct which was different from the /usr/include/dirent.h
889 one (this used to work, is it a glibc2 change?), so none of the
890 compat glob (which used /usr/include/dirent.h) or the system glob
891 worked. Restore use now the system dirent (and the system
892 DT_* constants), which are compatible with BSD ones.
894 9. Added a configure flag (--with-dumpdatespath) to specify
895 the location of dumpdates file. By default, it is
898 10. Added the "AUTHOR" and "AVAILABILITY" sections and
899 included the current date/version in man pages.
901 11. Corrected the estimation of remaining time when
902 the operator doesn't change the tapes quickly enough. This
903 was an old bug, I thought I corrected it, and discovered
904 that in fact it was corrected in two different places, so
905 the results canceled each other...
907 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
908 ===================================================================
910 1. Integrated multiple patches from RedHat, Debian and SuSE:
912 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
914 - several fixes in the man pages.
915 - update the default tape device to /dev/st0.
916 - many updates for Linux Alpha (byte ordering, size_t etc).
918 - use environment variable for TMPDIR (instead of /tmp).
919 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
920 - workaround egcs bug (RedHat bugs #4281 and #2989).
921 - wire $(OPT) throughout Makefile's.
923 2. Upgrade the dump revision to 1, making possible to dump filesystems
924 made with e2fsprogs-1.15 or newer. Nothing seems to break...
926 3. Fix some compile warnings, prototype all functions.
928 4. Use glibc err/glob instead of internal compatibility
929 routines (only if available).
931 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
932 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
934 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
935 ======================================================================
937 1. Integrated the changes from FreeBSD-3.1-RELEASE
938 (mostly bug fixes, buffer overruns, dump has now an "automatic
939 tape length calculation" flag, dump/restore can use kerberos now
940 (this is NOT tested), use environment variables for TAPE and
943 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
945 3. Corrected a bug in restore when using 'C' option with multi-volumes
946 tapes (files splited accros two tapes give "size changed" errors
949 4. Corrected the long standing bug when dumping multiple tapes.
950 This works for me, needs further testing.
952 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
953 ====================================================================
955 1. Dump now runs correctly on kernels 2.1.x
956 Fix made by Gerald Peters <gapeters@worldnet.att.net>
958 Changes between versions 0.4b2 and 0.4b3
959 ========================================
961 1. Use realpath() if available
965 Changes between versions 0.4b1 and 0.4b2
966 ========================================
968 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
971 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
973 3. Fixed configure.in to correctly handle --enable-rmt
975 Changes between versions 0.3 and 0.4b1
976 ======================================
978 1. Integrated the changes from 4.4BSD-Lite2
980 2. Integrated the patches from Debian and Red Hat
982 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
984 4. Changed dump to use the Ext2fs library to get block addresses. This
985 should solve the endianness problem on SparcLinux.
987 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
988 distribution's one) to use autoconf
990 6. Fixed a few minor bugs
992 Changes between versions 0.2e and 0.2f
993 ======================================
995 1. Added the creation of named pipes (fifos) in restore.
997 2. Added the -N flag in the restore manual page.
999 3. Added the file kernel.patch which contains the llseek() optimization
1000 patch for 1.2.x kernels.
1002 4. Fixed a bug in the restoration of symbolic links: owner and group were
1005 5. Integrated some changes from FreeBSD 2.2.
1007 6. Added a call to ftruncate() after restoring each file to restore
1008 correctly files ending by a hole.
1010 Changes between versions 0.2d and 0.2e
1011 ======================================
1013 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1014 with owner = root (0) and group = root/wheel/whatever (0).
1016 Changes between versions 0.2c and 0.2d
1017 ======================================
1019 1. Dump is now able to backup 2GB+ filesystems.
1021 2. Dump and restore can now be linked as static binaries.
1023 Changes between versions 0.2b and 0.2c
1024 ======================================
1026 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1028 Changes between versions 0.2a and 0.2b
1029 ======================================
1031 1. Really fixed the bug that I should have corrected in 0.2a.
1033 2. Enabled optimization again.
1035 Changes between versions 0.2 and 0.2a
1036 =====================================
1038 1. Disabled the optimization during compilation.
1040 Changes between versions 0.1 and 0.2
1041 ====================================
1043 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1044 the fs_type field (actually, I modified the file fstab.c to make it
1045 use the mntent functions).
1047 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1048 made by dump should be readable by the BSD restore and backups made
1049 by the BSD dump should be readable by restore. Unfortunately, this
1050 means that the dump format has changed between version 0.1 and version
1053 3. Dump is now able to backup a subtree, it is no longer limited to whole
1054 filesystems like the BSD version.
1056 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1059 Changes between versions 0.0 and 0.1
1060 ====================================
1062 1. Now create links rdump and rrestore during the `make install' step.
1064 2. Linux port specific bugs added to the manual pages
1066 3. Incorrect estimation of the number of tapes blocks fixed when doing
1067 incremental backups.
1069 4. Better ls-like format in restore in interactive mode.
