3 Changes between versions 0.4b32 and 0.4b33 (released ?????????????????)
4 =======================================================================
6 1. Added a note in the restore man page clarifying the question
7 'set the permissions on the current directory ?' asked by
8 restore at the end of treatment in -i and -x modes.
10 2. Fixed the endianess issues when reading compressed tapes.
11 Thanks to Dark Force <daq4th@users.sourceforge.net> for
12 reporting this bug and providing test cases.
14 3. Fixed the "ACL won't be dumped" warning message (which showed
15 an extra, unrelated error message). Thanks to Dragan Krnic
16 <dkrnic@lycos.com> for reporting this bug.
18 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
19 =======================================================================
21 1. Changed dump to use fcntl(F_SETLK) style locking instead
22 of flock() when locking the dumpdates file. With the old
23 locking scheme, a local user having read rights on the
24 dumpdates file could be able to do a Denial of Service attack
25 on dump. In order to lock the dumpdates file with the new
26 scheme, the user would need to have write access on the file.
27 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
28 reporting the bug (originally a bugtraq post).
30 2. Fixed interactive 'ls' which caused spurious errors warnings
31 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
32 <jorgen_ostling@users.sourceforge.net> for reporting this
35 3. Fixed dump's estimate when dealing with sparse inodes.
37 4. Modified dump to allow setting a blocksize bigger than 32kB
38 (raised the limit to 1024kB), because newer hardware needs
39 this for proper operation. Thanks to Dirk Traenapp
40 <dtraenapp@users.sourceforge.net> for reporting this.
42 5. Fixed a bug causing Dump to stop and report an error if an
43 inode number in the exclude file was followed by some amount
44 of whitespace. Thanks to Jeffrey Sofferin
45 <sofferin@users.sourceforge.net> for reporting this bug.
47 6. Fixed a bug which caused restore, in some particular cases,
48 to ask some 'scary' questions and leave a bunch of RSTTMP
49 directories behind when restoring incremental tapes. Thanks
50 to Philippe Troin <phil@fifi.org> for reporting this bug and
51 providing the test cases.
53 7. Changed the wording when inodes are excluded from dump:
54 replaced 'Added inode 7 to exclude list' with
55 'Excluding inode 7 (resize inode) from dump', as suggested
56 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
58 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
59 ===================================================================
61 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
62 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
63 <eros@lamel.bo.cnr.it> for reporting the bug.
65 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
66 ===================================================================
68 1. Made dump print out the ext2 logical block number in case of a read
69 error, which can be given as an argument to debugfs' ncheck command,
70 in order to find out the affected inode. Added note about this
71 usage in dump's man page.
73 2. Fixed a problem in restore when reading tapes written on big
74 endian machines with very old versions of dump. The patch was
75 contributed by George Helffrich <george@geology.bristol.ac.uk>.
77 3. Fixed the tape length calculation when using large tapes
78 and compression. Thanks to Georg Lippold
79 <g_lippold@sourceforge.net> for reporting the bug.
81 4. Added a new set of examples in dump_on_cd_2 directory, based
82 on dump_on_cd examples but somewhat enhanced, supporting DVD
83 media, and localized in english and german. Thanks to
84 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
86 5. Made dump save 32 bit UID/GID. Internally, this was achieved
87 by switching from the old BSD inode format to the new BSD
88 inode format, which means that the tape format was changed.
89 However, since all restore versions out there should
90 transparently support both inode formats, the change should
91 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
94 6. Fixed a lot of warnings in the code shown when compiling
95 with 'gcc -W'. Thanks to Matthias Andree
96 <matthias.andree@stud.uni-dortmund.de> for reporting this.
98 7. Fixed a small markup bug in the dump man page. Thanks to
99 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
102 8. Rewrote entirely the man pages using the tmac.an macro
103 package (Linux man page format) instead of the original BSD
104 format. They should be now cleaner and easier to modify.
106 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
107 ==================================================================
109 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
110 non Linux clients were misinterpreted. The description of the problem
111 (incompatible numbering in Linux mtio opcodes) is documented at
112 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
113 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
114 providing an excellent, cross-platform replacement for rmt in his
117 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
118 which caused restore to fail when the inode maps were not entirely
119 contained on the first volume (when using really small volumes or
120 when dumping a huge number of inodes).
122 3. Fixed a problem in dump, where files in subdirectories of directories
123 that have the nodump flag set (or being excluded with -e/-E) were
124 sometimes incorrectly dumped (instead of being excluded). The original
125 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
126 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
127 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
128 help testing the patch.
130 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
131 which makes one able to pipe the output of dump, by the net, to
132 a remote CD-burner server.
134 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
135 and use GNU's symbolic syntax over rmt instead of numerical values
136 to assure multiple platform compatibility.
138 6. Documented the -d option in restore.
140 7. Added a -v (verbose) mode to dump. For now it just prints the number
141 of the inode being dumped, but this could evolve in future versions
142 to include interesting debugging output.
144 8. Added a -o flag to restore, which automatically restores the current
145 directory permissions in -i or -x mode, without asking the operator
146 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
147 and Peter Samuel <peters@e-smith.com>.
149 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
150 ====================================================================
152 1. Fixed a bug in the QFA feature which could have caused
153 a bad tape positionning on restore (causing extra delays in
154 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
156 2. Added a small note in the dump man page specifying that
157 there should be no white space between the option letter and
158 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
160 3. Made restore work with older versions of the readline library,
161 by checking in configure for several extended symbols. Restore
162 can now be compiled with a readline as old as the 2.0 release
163 (though it may be a good idea to upgrade it to a more recent
164 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
165 reporting the build failures.
167 4. Fixed a performance problem with the QFA file creation in
168 dump, which made unnecessary seeks on the tape slowing down
169 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
170 reporting this issue.
172 5. Removed the inclusion of some kernel headers in the dump
173 source, which prevented the compile in some kernel/glibc
174 headers/architecture combination. Thanks to Bdale Garbee
175 <bdale@gag.com> for reporting the bug.
177 6. Added the appropriate error message when dump fails to
178 open the output file for writing. Thanks to Amith Varghese
179 <amithv@yahoo.com> for reporting this bug.
181 7. Made restore able to understand large Solaris ufsdump tapes
182 (containing inodes bigger than 4194304). Sun have introduced
183 an "extension" to the dump tape format when dealing with
184 those inodes, which was uncorrectly handled by Linux restore.
185 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
186 providing a test case.
188 8. Added the -m parameter to dump which optimises the output for
189 inodes having been changed but not modified since the last dump
190 ('changed' and 'modified' have the meaning defined in stat(2)).
191 For those inodes, dump will save only the metadata, instead of
192 saving the entire inode contents. Inodes which are either
193 directories or have been modified since the last dump are saved
194 in a regular way. Uses of this flag must be consistent, meaning
195 that either every dump in an incremental dump set have the flag,
198 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
199 =======================================================================
201 1. Fixed behaviour of dump when exceeding resource limits
204 2. Added the -L flag to restore to allow the user to specify a
205 maximal allowed number of miscompares when using restore
206 with the -C option to check the backup.
208 3. Detailed the manual entry for the -N option of restore.
210 4. Added the -a flag to restore to make able doing unattended
211 restores in -i or -x mode (automatically walks through the
212 multiple dump volumes).
214 5. Extended the QFA mode to work with local files and/or
215 remote tapes and files. This way, restore can know in advance
216 the tape number and the offset for the inodes to extract and
217 can minimize the extraction time by seeking directly to the
220 6. Added the -A <archive> option to both dump and restore,
221 which makes dump to archive a dump table-of-contents in
222 the specified file to be used by restore to determine
223 whether a file is in the dump file that is being restored.
224 (the archive file syntax is also compatible with the
225 Solaris ufsdump generated one).
227 7. Small fix in restore making it able to read some (broken ?)
228 Solaris ufsdump tapes.
230 8. Fixed dump to correctly recognise the root filesystem when using
231 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
232 for reporting this bug.
234 9. Added the -P <file> option to restore to create a
235 Quick File Access file from an already made dump. Patch
236 contributed by Uwe Gohlke <uwe@ugsoft.de>.
238 10. Made restore compile and run on Solaris, making it a
239 possible replacement for the standard ufsrestore. Port was
240 contributed by Uwe Gohlke <uwe@ugsoft.de>.
242 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
243 =====================================================================
245 1. Added a set of backup scripts from Eugenio Diaz
246 <getnito@yahoo.com> in the examples section. It features
247 automatic (cron based) full and incremental dumping of
248 several filesystems on a separate filesystem.
250 2. Fixed a off-by-one miscalculation which disabled dumping
251 a one letter subdirectory. Thanks to Chris Siebenmann
252 <cks@utcc.utoronto.ca> for reporting the bug.
254 3. Fixed several restore bugs occuring when trying to
255 restore some missing files on the tape. Thanks to Chris
256 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
258 4. Fixed --with-ldopts configure argument passing, installing from
259 a separate object directory, makefile cleanups contributed
260 by <splite@purdue.edu>.
262 5. Fix a bug which could caused, in some conditions, the highest
263 number inode of a filesystem, to not be dumped. Many thanks
264 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
267 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
268 =======================================================================
270 1. Added a mini howto from Patrick Walsh in the examples
273 2. Minor man pages syntax corrections. Thanks to
274 Chris Danis <screechco@home.com> for reporting the bugs.
276 3. Added a script from David B. Peterson <dave@toppledwagon.com>
277 to the examples section. It features dumping several
278 filesystems to a remote tape drive upon ssh.
280 4. Added a patch provided by Richard Jones <rich@annexia.org>
281 which allows BRADEMAX (number of read errors tolerated by
282 dump) to be adjusted using the -I option.
284 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
285 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
288 6. Add the -l option to restore to specify if, when doing a
289 remote restore, the file used to access the backup is a
290 regular file (the defaults being a tape drive). Restore needs
291 to know this information when reading a remote compressed
292 dump. Previously, this information was autodetected, but
293 the autodetection code fails (with ioctl: Inappropriate ioctl
294 for device) when using a non Linux remote box. Thanks to
295 many users and especially to Eros Albertazzi
296 <eros@lamel.bo.cnr.it> for reporting this.
298 7. Found a workaroung for the dump deadlock problem (3 childs
299 stuck in pause(), father in read()). The workaround seems
300 to work for me and several beta-testers. If it doesn't work
301 for you, please report back.
303 8. Updated the RPM spec file (BuildPrereq, URL etc).
305 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
306 ========================================================================
308 1. Fixed the permissions of a newly created QFA file by dump.
310 2. Cleaned up the source of dump (the external variables
311 definition was a complete mess, making possible to have
314 3. Fixed restore to use the full tape volume path when doing
315 a compare (since it changes the working directory to the
316 filesystem being compared in the process).
318 4. Added the -q option to dump which makes dump abort
319 whenever it needs operator attention. It should be
320 easier to use dump in scripts with this option.
322 5. Detect the use of incompatible options to dump and
323 refuse them (like -a and -B options together).
325 6. Added bzip2 compression to dump/restore (use option -j level
326 to select it). Note that you will need a restore version
327 >= 0.4b24 in order to restore a bzip2 compressed dump.
328 The same warning as for the zlib compression applies:
329 the tape format of a bzip2 dump is not compatible with the
330 original BSD tape format.
332 7. Fixed a overflow problem in dump corrupting the dump when
333 very large files were encountered. Thanks to Vladimir Nadvornik
336 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
337 kernel buffer/page cache before starting the dump, helping
338 a bit those who use dump on mounted filesystems. Thanks to
339 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
342 9. Updated the RPM spec file following the RedHat changes
343 (dynamically linked binaries now in /usr/sbin etc).
345 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
346 which enables restore to recognise multi volume compressed dumps
347 done on CD. Included his scripts for dump (which pipe the dump
348 output directly into cdrecord) and restore. There is now
349 possible to to backups to CD on the fly!
351 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
352 ===================================================================
354 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
355 Marcus Meissner (Caldera International Security Dept.).
357 2. Implement the Sun rmt extended protocol. Patch submitted
358 by Ian Gordon <iangordon@users.sourceforge.net>.
360 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
361 the linux kernel header. This ensures that dump always has the
362 latest version of this file. Patch submitted by
363 Andreas Dilger <adilger@turbolinux.com>.
365 4. Report any filesystem present in either /etc/fstab with a
366 positive passno or /etc/dumpdates in dump -w output.
367 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
369 5. Fixed the looping problem in dump introduced in the
372 6. Changed the -B option of dump to limit the size of
373 _compressed_ output per volume if compression is on.
374 Patch contributed by Helmut Jarausch
375 <jarausch@igpm.rwth-aachen.de>. Note however that, since
376 it is impossible to predict the size of the compressed
377 data before doing the compression, the -B limit is a bit
380 7. Fixed a bug in reading the operator typed file/tape path for
381 the next volume in restore.
383 8. Implemented a "-F script" option to restore which permits the
384 user to specify a script which will be launched at the
385 beginning of each tape, useful for automatic programming of
386 tape changers for example. See the restore man page for the
387 script parameters and return codes.
389 9. Small fix for the QFA routines provided by Uwe Gohlke
390 <uwe@ugsoft.de>, and some recommendations for QFA uses in
393 10. Fixed the multivolume restoring where making a mistake
394 to the 'Mount next tape' prompt caused several blocks to
397 11. Enhanced the -e option of dump to take as a parameter a
398 comma separated list of inode numbers.
400 12. Added the -E option to dump which specify a file containing
401 inode numbers to exclude from the dump.
403 13. Fixed the compressed multi-volume dump + restore.
405 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
406 ==================================================================
408 1. Made dump report the number of blocks dumped per volume.
409 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
411 2. Fix a bug in dump where waiting too much at the 'change volumes'
412 question caused the volume to be rewritten. Thanks to
413 Graham Reed <greed@users.sourceforge.net> for reporting the
414 bug and providing a patch.
416 3. Added a compression option to dump, contributed by Jerry
417 Peters <gapeters@worldnet.att.net>.
419 WARNING: the compression works only on files/pipes and
420 drives supporting variable block size.
422 WARNING2: tapes created using the compression feature are
423 incompatible with the standard dump tape format, and a
424 version of restore >= 0.4b22 will be needed for extraction.
426 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
427 architectures. Thanks to Paul Slootman <paul@debian.org> for
428 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
431 5. Many cleanups (CPP defines, const char warnings, check of
432 ext2fs COMPAT flags, time_t cleanups, added libext2 version
433 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
435 6. Made --prefix option work in configure. All the install path
436 are now based on the configure parameters.
438 7. Added the Quick File Access mode in dump/restore, contributed
439 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
440 a file tape position for each inode, and this file is used by
441 restore (if called with parameter Q and the filename)
442 to directly position the tape at the file restore is currently
443 working on. This saves hours when restoring single files from
444 large backups, saves the tapes and the drive's head. Use
445 --enable-qfa option of configure to compile in the QFA support.
447 8. Added the possibility to dump several files and directories
448 in a single invocation of dump. Thanks to Uwe Gohlke
449 <uwe@ugsoft.de> for implementing this option.
451 9. Fixed the dumping and restoring of files with holes
452 (files ending with holes didn't get dumped or restored
455 10. Fixed a socket descriptor leak in dump, which leaved opened
456 3 file descriptors per dump process (and there is one dump
459 11. Fixed dump large file system support, by explicit use of
460 open64/lseek64/etc functions (explicit use needed because
461 e2fsprogs libraries don't behave well when compiled with
462 FILE_OFFSET_BITS=64).
464 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
465 ======================================================================
467 1. Fixed some bugs in the dump -w|-W logic introduced by
468 the previous version. Thanks to Andreas Dilger
469 <adilger@turbolinux.com> for his help on this one.
471 2. Fixed again a compilation problem when using old e2fs
472 headers (filesystem label related). Thanks to many users
473 who reported this stupid error.
475 3. Fixed a build problem on old lib5 based systems dealing with
476 _PATH_MNTTAB being undefined. Thanks to John Adams
477 <johna@onevista.com> for reporting the bug.
479 4. Improved the error detection in restore when creating
480 the temporary files in TMPDIR. Now restore will corectly
481 report a 'no space left on device' error instead of
482 strange errors which could imply an archive corruption.
483 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
484 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
486 5. Added the throughput information in dump's progression
487 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
490 6. Use libext2fs's inode scanning routines, which are particularly
491 robust when dealing with errors (especially when having some
492 bad blocks on the filesystem). Many thanks to Colin
493 <colin@horizon.com> for reporting the bug, investigating
494 the issues, finding a workaround, writing the patch and
495 fully testing it... (of course, if this patch will break
496 anything, he is to blame for :-)).
498 7. Made dump and restore LFS aware. Dump can dump a filesystem
499 containing large files, generate a large file on output and
500 restore can restore them. This feature is not enabled by
501 default, use --enable-largefile option of configure to enable
502 it (you need to have a LFS aware glibc though). Thanks to
503 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
504 and to Theodore T'so <tytso@valinux.com> for his always
507 8. Made dump ask upon a tape write error if it should rewrite
508 the current volume (assume this is a bad tape) or if it should
509 assume an end-of-tape condition (useful for tape drives which
510 behaves badly at the end of the tape). Thanks to Andreas
511 Dilger <adilger@turbolinux.com> for the suggestion.
513 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
514 =======================================================================
516 1. Fixed a small compilation problem due to a change
517 in the definintion of the struct sigaction in
518 glibc 2.0 / libc5. Thanks to Gunther Schlegel
519 <schlegel@riege.de> for reporting the bug and to
520 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
523 2. Modified the label and uuid analysis in order to be
524 self-contained (independant of kernel/libc headers). This
525 should fix the compile with older kernel/libc headers and
526 will preserve the functionality. Thanks to Bernhard Erdmann
527 <bernhard.erdmann@gmx.de> for reporting the bug.
529 3. The 'exclude inode' option, if applied to a directory
530 inode, excludes now correctly all the leaves of this
531 directory. Thanks to John R. Dennison
532 <gerdesas@users.sourceforge.net> for reporting the bug.
534 4. Fixed the '-e' option to disable the possibility
535 to exclude the root inode (which causes the dumps to
536 be unreadable by restore). Prevented array overflow
537 when multiple -e options are used.
539 5. Fixed dump to correctly interpret a filesystem argument
540 which is a mountpoint and it is not an absolute path
541 (as specified in the fstab). Thanks to Bernhard R. Erdmann
542 <be@berdmann.de> for reporting the bug.
544 6. Made dump able to backup files larger than 2 GB. Note that
545 dump still doesn't cope with files larger than 4 GB.
547 7. Restore the real uid and gid before invoking an external
548 RSH program (big hole when dump or restore is suid root!).
550 8. Get the values for the default tape device and the location
551 of fstab file from the system headers. Thanks to
552 Andreas Dilger <adilger@turbolinux.com> for the patch.
554 9. Made dump -w|-W report all recognized filesystems
555 present in either /etc/fstab or /etc/dumpdates, and present
556 the list in the same order as in fstab file. Thanks
557 to Andreas Dilger <adilger@turbolinux.com> for the patch.
559 10. Made dump's -a (automatic end of tape detection) the
560 default. Specifying one of -B, -c, -d or -s options will
561 override the EOM detection. Thanks to Andreas Dilger
562 <adilger@turbolinux.com> for the patch.
564 11. Save the ext2 filesystem label into the dump volume label.
565 Specifying a volume label on the command line (-L option)
566 will override this feature. Thanks to Andreas Dilger
567 <adilger@turbolinux.com> for the patch.
569 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
570 =====================================================================
572 1. Fixed the signal handling in dump (which I broke in 0.4b17)
573 which was causing several strange dump failures (dump
574 hanged or segmentation faults etc).
576 2. Specified the default blocksize in the dump man page.
578 3. Changed two info messages of restore to be written on stdout
579 instead of stderr in order to leave stderr only for errors
580 or warnings. Thanks to Stephen Atwell
581 <satwell@urbana.css.mot.com> for the suggestion.
583 4. Corrected an off by one calculation which prevented
584 dumping a directory having a 1 character name length.
585 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
586 for reporting the bug.
588 5. Reinforce dump in order to allow only level 0 and no
589 -u option when dumping a subdirectory, and document
590 this in the man page. Thanks to Bernhard Erdmann
591 <bernhard.erdmann@gmx.de> for reporting the bug.
593 6. Fixed a small harmless bug in restore which caused
594 in some conditions hard links to be restored several
595 times (therefore generation some warning messages).
596 Thanks to Kenneth Porter <shiva@well.com> for
599 7. Updated the RPM spec file to the latest RedHat version,
600 providing FHS packaging and other cosmetic changes.
601 You will need RPM version >= 3.0.5 in order to build the RPM.
603 8. Updated the configure script to check for libtermcap
604 before checking for libreadline, because we need this
605 library in order to compile the readline support.
607 9. Made dump understand the LABEL= and UUID= notation
608 both in /etc/fstab and on the command line. Note that
609 you will need the /proc filesystem in order to use
610 these notations. Thanks to Erik Troan <ewt@redhat.com>
611 for providing the patch.
613 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
614 ===================================================================
616 1. Fixed a potential buffer overflow in restore. Thanks
617 to Stan Bubrouski <satan@fastdial.net> for reporting
620 2. Fixed a readline-related bug which prevented
621 'cat DUMPFILE | restore -i -f -' from working. Thanks
622 to Charles Karney <karney@users.sourceforge.net>
625 3. Changed a few "panic" into "exit", causing restore to
626 be more stable against some attacks (like the last one
627 reported on Bugtraq, although the last version of restore
628 was not vulnerable - just dumped core). Thanks to
629 Andreas Hasenack <andreas@conectiva.com.br> for reporting
632 4. Removed the suid-root bit on dump and restore in the
633 default build (and generated RPMs). It should be safer
634 now. Users who need the suid-root capabilities in order
635 to make network backups should read first the man page
636 of dump and enable the suid bit manually.
638 5. Added -ltermcap to the compile parameters for restore
639 when using readline support, in order to make the compile
640 process work on some systems (SuSE ?). Thanks to
641 Patrik Schindler <poc@pocnet.net> for reporting the bug.
643 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
644 ====================================================================
646 1. The -F script is called now *only* at the end of a tape,
647 not at the end of the dump. Thanks to Christian Haul
648 <haul@informatik.tu-darmstadt.de> for the bug report.
650 Normally, the device name and the current volume number
651 are passed on the command line of the script. However,
652 if you want the old style script (with no arguments
653 passed on the command line), you can enable it in
654 configure with the --enable-oldstylefscript.
656 2. Use posix signal handling to preserve dump functionality
657 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
660 3. Made the exit code of restore in case of a 'C'ompare
661 command reflect the result of the compare. An exit status
662 of 0 means the dump archive is correct, 1 means tape errors,
663 2 means that some files were modified. Thanks to Kenneth Porter
664 <shiva@well.com> for the suggestion.
666 4. Made (finally) quotes work in interactive restore.
668 5. Small fixes in order to allow dump to compile with a
669 really old e2fsprogs version. Thanks to Ian Zimmerman
670 <itz@speakeasy.org> for the bug report.
672 6. Add GNU readline capabilities to interactive restore.
673 Use configure's --enable-readline flag to enable this feature.
674 Thanks to Patrik Schindler <poc@pocnet.net> for the
677 7. Do the compare on the fly in restore 'C' mode (this will
678 allow not to exhaust the available /tmp space when
679 ccmparing large files). Thanks to Kenneth Porter
680 <shiva@well.com> for the suggestion.
682 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
683 ====================================================================
685 1. Fixed some several duplicate 'DUMP: DUMP:' in the
688 2. Corrected the estimation of blocks to dump. Note that
689 this is still wrong for large directory inodes, due
690 to the size of a BSD directory entry on the tape
691 (estimation is based on the size of the ext2 directory,
692 which is smaller because it doesn't contain the null
693 character at the end).
695 3. Made dump report the total number of MB written to
696 tape at the end of run. Thanks to W. Reilly Cooley
697 <wcooley@nakedape.cc> for the patch.
699 4. Added the -X option to restore giving the possibility
700 to read the names of the files to be extracted/listed
701 from a text file (in addition of the command line).
702 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
705 5. Added the device name and the current volume number
706 as arguments to the end of tape script (dump -F option).
708 6. Made the multi-volume dump work again (after having
709 broken it in 0.4b15).
711 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
712 ===================================================================
714 1. Added a prompt command in interactive restore mode. Thanks
715 to Andreas Dilger <adilger@home.com> for the patch.
717 2. Fixed a buffer overflow problem in dump (caused by
718 not checking the size of the filesystem parameter).
719 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
720 reporting this on Bugtraq (and to several dump users
721 who forwarded me his mail).
723 3. Added the '-F script' option to dump in order to
724 launch a script at the end of each tape (to be used
725 with a tape changer, or to notify the sysadmin by
728 4. Fixed a bug in restore compare code caused by the changes
731 5. Fixed the treatment of options using the old BSD syntax
732 in both dump and restore.
734 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
735 =======================================================================
737 1. Fixed a bug in dump which may have caused invalid deleted
738 directories to be dumped out if they were deleted after the
739 mapping pass. This could occure on active filesystem and lead
740 to heap corruption (causing dump malfunction in many possible ways).
741 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
742 bug and submitting the patch.
744 2. Fixed the handling of the filesystem parameter in dump. A
745 '/mnt/disk' parameter caused the disk contents to be dumped,
746 but a '/mnt/disk/' parameter caused the mountpoint directory
747 to be dumped (generally an empty directory).
749 3. Improved the output of dump in order to tell which directory
750 it is currently dumping (when dumping a subtree).
752 4. Added the '-e' exclude inode option to dump. Thanks to
753 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
755 5. Added a REPORTING-BUGS file in order to provide a guide
756 on how to correctly report a bug in dump/restore.
758 6. Fixed a restore problem when restoring a hard link to an inode
759 having the immutable or append-only attribute set. Thanks to
760 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
762 7. Fixed a compatibility problem between dumps made on little
763 endian machines (the format was correct) and big endian
764 machines (the format was incorrect). This fix break the
765 compatibility with the older dumps made on big endian
766 machines (sparc, m86k, ppc etc). For the first time in
767 linux dump's history (I believe), the dumps made by *BSD,
768 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
769 so interchangeable. Thanks to Rob Cermak
770 <cermak@ahab.rutgers.edu> for submitting the bug and
771 helping me test the fix.
773 8. Fixed the way dump reports the remaining percent/time, if
774 the number of blocks actually dumped exceeds the estimated
775 number of blocks. Thanks to Jean-Paul van der Jagt
776 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
778 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
779 ======================================================================
781 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
782 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
784 2. Removed the requirement to build the RPM as root from the
785 spec file. Thanks to Christian Weisgerber
786 <naddy@mips.rhein-neckar.de> for submitting this.
788 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
789 causing dump to block when dumping really huge filesystems.
790 Many thanks to Patrik Schindler <poc@pocnet.net> for
791 helping me find this bug.
793 4. Fixed the treatment for an interrupt signal when dump access
794 the remote tape through RSH. Thanks to Christian Weisgerber
795 <naddy@mips.rhein-neckar.de> for providing the patch.
797 5. Fixed a bug which was causing dump/restore to display
798 garbage characters instead of the remote host name.
800 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
801 =====================================================================
803 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
804 <kukuk@suse.de> for submitting the patch.
806 2. Fix for the exit code when using the size estimate option of
807 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
808 submitting the patch.
810 3. Handle EINTR in atomical reads/writes in dump, which was causing
811 dump to fail on some systems. Thanks to Eric Jergensen
812 <eric@dvns.com> for reporting the bug and submitting the patch.
814 4. Handle more than 16 characters for the device names in dumpdates.
815 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
816 tracking down the problem and proposing the solution.
818 5. Fixed a bug in dump which prevented the creation of the
819 dumpdates file when doing a 0-level dump without already
820 having a dumpdates file. Thanks to Patrik Schindler
821 <poc@pocnet.net> for reporting the bug.
823 6. Changed the way dump 'S' flag reports the size estimate
824 from number of blocks into bytes (making it compatible
825 with the Solaris version, and simplifying things for
826 amanda users). Thanks to Jason L Tibbitts III
827 <tibbs@math.uh.edu> for reporting the bug.
829 7. Fixed a compatibility problem in linux/alpha dump tape format.
830 Now the linux/alpha dump are (again) compatible with the
831 other dump formats. But this breaks compatibility with
832 older dumps made on alpha. Thanks to Mike Tibor
833 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
835 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
836 ======================================================================
838 1. Added a '--enable-kerberos' to configure.
840 2. Added a 'S' option to dump which determines the amount of space
841 that is needed to perform the dump without actually doing it, similar
842 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
843 <cermak@ahab.rutgers.edu>.
845 3. Added a 'M' multi-volume option to dump and restore which enables
846 dumping to multiple files (useful when dumping to an ext2
847 partition to make several dump files in order to bypass the 2GB
848 file size limitation). The 'f' argument is treated as a prefix and
849 the output files will be named <prefix>001, <prefix>002 etc. With
850 the 'M' flag, restore automatically selects the right file without
851 asking to enter a new tape each time.
853 4. Fixed a memory leak which was causing dump to grow very big
854 (270MB when dumping a 10GB filesystem...). Thanks to Jason
855 Fearon <jasonf@netrider.org.au> for reporting the bug.
857 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
858 ======================================================================
860 1. Make configure test if the system glob routines support
861 extended syntax (ALTDIRFUNC). If not, use the internal glob
862 routines instead of system ones. Thanks to Bernhard Sadlowski
863 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
864 and helping me resolve this and other minor libc5 compiling
867 2. Fix a problem when dumping a ext2fs with the 'filetype'
868 feature enabled. Thanks to Patrick J. LoPresti
869 <patl@cag.lcs.mit.edu> for reporting the bug and to
870 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
872 3. Made the nodump flag work on directories. A directory which
873 has the nodump flag gets never dumped, regardless of its
876 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
877 which allows dump on an active ext3 filesystem. However, this
878 is a "quick and dirty" patch which enables backup of an ext3
879 filesystem through the ext2 compatibility (by ignoring the
880 NEEDS_RECOVERY bit). The journal file is not recognized and
881 it is dumped (it should not).
883 5. Test the superblock compatibility flags when dumping, in order
884 to be sure that we know how to deal with specific features.
886 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
887 ====================================================================
889 1. Use lchown instead of chown, fixing a possible security problem
890 when restoring symlinks (a malicious user could use this
891 to deliberately corrupt the ownership of important system files).
892 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
893 this and providing the patch.
895 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
896 ====================================================================
898 1. Put dump sources under CVS, added Id tags in all files so
899 one can use 'ident' on binary files.
901 2. Added the dump/restore version in the usage text so one can
902 easily verify the version he is using.
904 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
905 a va_start/va_end problem on linux-ppc (always call va_start
906 va_end in pairs each time we use a vararg function).
908 4. Added again the DT_* constants because old libc does not
909 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
910 for submitting the bug report.
912 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
913 this should enable dumping big (huge) filesystems.
915 6. Added the RSH environment variable in order to be able to
916 use a rsh replacement like ssh when doing remote backups (and
917 bypass the security limitations of rcmd). Now you can do remote
918 backups without being root (or making dump setuid root).
920 7. Modified again the way dumpdates works. For incremental dumps,
921 we need to read dumpdates even if we are not using 'u' option.
922 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
925 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
926 ===================================================================
928 1. Removed the 'k' flag from the restore 'about' text if kerberos
931 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
932 to them (fsetflags takes a char*, setflags an open fd!).
934 3. (f)setflags is called only if the flags aren't empty. If the
935 file is a special file, a warning is printed, because changing
936 flags implies opening the device. Normally, a special file
937 should not have any flag... (Debian bug #29775, patch provided
938 by Abhijit Dasgupta <abhijit@ans.net>).
940 4. Made possible to dump a file system not mentioned in /etc/fstab.
941 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
943 5. Changed the default behaviour to not create dumpdates
944 unless 'u' option is specified. Removed the old "debian-patch"
945 which provided the same thing. (Debian bug #38136, #33818).
947 6. Removed all those dump*announce, since they were getting old...
949 7. Added warning messages if dumpdates does not exist and
950 when an inferior level dump does not exist (except for a level 0
953 8. Debugged the glob calls in interactive mode: restore used a
954 dirent struct which was different from the /usr/include/dirent.h
955 one (this used to work, is it a glibc2 change?), so none of the
956 compat glob (which used /usr/include/dirent.h) or the system glob
957 worked. Restore use now the system dirent (and the system
958 DT_* constants), which are compatible with BSD ones.
960 9. Added a configure flag (--with-dumpdatespath) to specify
961 the location of dumpdates file. By default, it is
964 10. Added the "AUTHOR" and "AVAILABILITY" sections and
965 included the current date/version in man pages.
967 11. Corrected the estimation of remaining time when
968 the operator doesn't change the tapes quickly enough. This
969 was an old bug, I thought I corrected it, and discovered
970 that in fact it was corrected in two different places, so
971 the results canceled each other...
973 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
974 ===================================================================
976 1. Integrated multiple patches from RedHat, Debian and SuSE:
978 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
980 - several fixes in the man pages.
981 - update the default tape device to /dev/st0.
982 - many updates for Linux Alpha (byte ordering, size_t etc).
984 - use environment variable for TMPDIR (instead of /tmp).
985 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
986 - workaround egcs bug (RedHat bugs #4281 and #2989).
987 - wire $(OPT) throughout Makefile's.
989 2. Upgrade the dump revision to 1, making possible to dump filesystems
990 made with e2fsprogs-1.15 or newer. Nothing seems to break...
992 3. Fix some compile warnings, prototype all functions.
994 4. Use glibc err/glob instead of internal compatibility
995 routines (only if available).
997 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
998 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1000 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1001 ======================================================================
1003 1. Integrated the changes from FreeBSD-3.1-RELEASE
1004 (mostly bug fixes, buffer overruns, dump has now an "automatic
1005 tape length calculation" flag, dump/restore can use kerberos now
1006 (this is NOT tested), use environment variables for TAPE and
1009 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1011 3. Corrected a bug in restore when using 'C' option with multi-volumes
1012 tapes (files splited accros two tapes give "size changed" errors
1015 4. Corrected the long standing bug when dumping multiple tapes.
1016 This works for me, needs further testing.
1018 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1019 ====================================================================
1021 1. Dump now runs correctly on kernels 2.1.x
1022 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1024 Changes between versions 0.4b2 and 0.4b3
1025 ========================================
1027 1. Use realpath() if available
1029 2. Report statistics
1031 Changes between versions 0.4b1 and 0.4b2
1032 ========================================
1034 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1037 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1039 3. Fixed configure.in to correctly handle --enable-rmt
1041 Changes between versions 0.3 and 0.4b1
1042 ======================================
1044 1. Integrated the changes from 4.4BSD-Lite2
1046 2. Integrated the patches from Debian and Red Hat
1048 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1050 4. Changed dump to use the Ext2fs library to get block addresses. This
1051 should solve the endianness problem on SparcLinux.
1053 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1054 distribution's one) to use autoconf
1056 6. Fixed a few minor bugs
1058 Changes between versions 0.2e and 0.2f
1059 ======================================
1061 1. Added the creation of named pipes (fifos) in restore.
1063 2. Added the -N flag in the restore manual page.
1065 3. Added the file kernel.patch which contains the llseek() optimization
1066 patch for 1.2.x kernels.
1068 4. Fixed a bug in the restoration of symbolic links: owner and group were
1071 5. Integrated some changes from FreeBSD 2.2.
1073 6. Added a call to ftruncate() after restoring each file to restore
1074 correctly files ending by a hole.
1076 Changes between versions 0.2d and 0.2e
1077 ======================================
1079 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1080 with owner = root (0) and group = root/wheel/whatever (0).
1082 Changes between versions 0.2c and 0.2d
1083 ======================================
1085 1. Dump is now able to backup 2GB+ filesystems.
1087 2. Dump and restore can now be linked as static binaries.
1089 Changes between versions 0.2b and 0.2c
1090 ======================================
1092 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1094 Changes between versions 0.2a and 0.2b
1095 ======================================
1097 1. Really fixed the bug that I should have corrected in 0.2a.
1099 2. Enabled optimization again.
1101 Changes between versions 0.2 and 0.2a
1102 =====================================
1104 1. Disabled the optimization during compilation.
1106 Changes between versions 0.1 and 0.2
1107 ====================================
1109 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1110 the fs_type field (actually, I modified the file fstab.c to make it
1111 use the mntent functions).
1113 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1114 made by dump should be readable by the BSD restore and backups made
1115 by the BSD dump should be readable by restore. Unfortunately, this
1116 means that the dump format has changed between version 0.1 and version
1119 3. Dump is now able to backup a subtree, it is no longer limited to whole
1120 filesystems like the BSD version.
1122 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1125 Changes between versions 0.0 and 0.1
1126 ====================================
1128 1. Now create links rdump and rrestore during the `make install' step.
1130 2. Linux port specific bugs added to the manual pages
1132 3. Incorrect estimation of the number of tapes blocks fixed when doing
1133 incremental backups.
1135 4. Better ls-like format in restore in interactive mode.
