3 Changes between versions 0.4b27 and 0.4b28 (released ?????????????????)
4 =======================================================================
6 1. Fixed a bug in the QFA feature which could have caused
7 a bad tape positionning on restore (causing extra delays in
8 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
10 2. Added a small note in the dump man page specifying that
11 there should be no white space between the option letter and
12 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
14 3. Made restore work with older versions of the readline library,
15 by checking in configure for several extended symbols. Restore
16 can now be compiled with a readline as old as the 2.0 release
17 (though it may be a good idea to upgrade it to a more recent
18 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
19 reporting the build failures.
21 4. Fixed a performance problem with the QFA file creation in
22 dump, which made unnecessary seeks on the tape slowing down
23 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
26 5. Removed the inclusion of some kernel headers in the dump
27 source, which prevented the compile in some kernel/glibc
28 headers/architecture combination. Thanks to Bdale Garbee
29 <bdale@gag.com> for reporting the bug.
31 6. Added the appropriate error message when dump fails to
32 open the output file for writing. Thanks to Amith Varghese
33 <amithv@yahoo.com> for reporting this bug.
35 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
36 =======================================================================
38 1. Fixed behaviour of dump when exceeding resource limits
41 2. Added the -L flag to restore to allow the user to specify a
42 maximal allowed number of miscompares when using restore
43 with the -C option to check the backup.
45 3. Detailed the manual entry for the -N option of restore.
47 4. Added the -a flag to restore to make able doing unattended
48 restores in -i or -x mode (automatically walks through the
49 multiple dump volumes).
51 5. Extended the QFA mode to work with local files and/or
52 remote tapes and files. This way, restore can know in advance
53 the tape number and the offset for the inodes to extract and
54 can minimize the extraction time by seeking directly to the
57 6. Added the -A <archive> option to both dump and restore,
58 which makes dump to archive a dump table-of-contents in
59 the specified file to be used by restore to determine
60 whether a file is in the dump file that is being restored.
61 (the archive file syntax is also compatible with the
62 Solaris ufsdump generated one).
64 7. Small fix in restore making it able to read some (broken ?)
65 Solaris ufsdump tapes.
67 8. Fixed dump to correctly recognise the root filesystem when using
68 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
69 for reporting this bug.
71 9. Added the -P <file> option to restore to create a
72 Quick File Access file from an already made dump. Patch
73 contributed by Uwe Gohlke <uwe@ugsoft.de>.
75 10. Made restore compile and run on Solaris, making it a
76 possible replacement for the standard ufsrestore. Port was
77 contributed by Uwe Gohlke <uwe@ugsoft.de>.
79 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
80 =====================================================================
82 1. Added a set of backup scripts from Eugenio Diaz
83 <getnito@yahoo.com> in the examples section. It features
84 automatic (cron based) full and incremental dumping of
85 several filesystems on a separate filesystem.
87 2. Fixed a off-by-one miscalculation which disabled dumping
88 a one letter subdirectory. Thanks to Chris Siebenmann
89 <cks@utcc.utoronto.ca> for reporting the bug.
91 3. Fixed several restore bugs occuring when trying to
92 restore some missing files on the tape. Thanks to Chris
93 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
95 4. Fixed --with-ldopts configure argument passing, installing from
96 a separate object directory, makefile cleanups contributed
97 by <splite@purdue.edu>.
99 5. Fix a bug which could caused, in some conditions, the highest
100 number inode of a filesystem, to not be dumped. Many thanks
101 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
104 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
105 =======================================================================
107 1. Added a mini howto from Patrick Walsh in the examples
110 2. Minor man pages syntax corrections. Thanks to
111 Chris Danis <screechco@home.com> for reporting the bugs.
113 3. Added a script from David B. Peterson <dave@toppledwagon.com>
114 to the examples section. It features dumping several
115 filesystems to a remote tape drive upon ssh.
117 4. Added a patch provided by Richard Jones <rich@annexia.org>
118 which allows BRADEMAX (number of read errors tolerated by
119 dump) to be adjusted using the -I option.
121 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
122 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
125 6. Add the -l option to restore to specify if, when doing a
126 remote restore, the file used to access the backup is a
127 regular file (the defaults being a tape drive). Restore needs
128 to know this information when reading a remote compressed
129 dump. Previously, this information was autodetected, but
130 the autodetection code fails (with ioctl: Inappropriate ioctl
131 for device) when using a non Linux remote box. Thanks to
132 many users and especially to Eros Albertazzi
133 <eros@lamel.bo.cnr.it> for reporting this.
135 7. Found a workaroung for the dump deadlock problem (3 childs
136 stuck in pause(), father in read()). The workaround seems
137 to work for me and several beta-testers. If it doesn't work
138 for you, please report back.
140 8. Updated the RPM spec file (BuildPrereq, URL etc).
142 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
143 ========================================================================
145 1. Fixed the permissions of a newly created QFA file by dump.
147 2. Cleaned up the source of dump (the external variables
148 definition was a complete mess, making possible to have
151 3. Fixed restore to use the full tape volume path when doing
152 a compare (since it changes the working directory to the
153 filesystem being compared in the process).
155 4. Added the -q option to dump which makes dump abort
156 whenever it needs operator attention. It should be
157 easier to use dump in scripts with this option.
159 5. Detect the use of incompatible options to dump and
160 refuse them (like -a and -B options together).
162 6. Added bzip2 compression to dump/restore (use option -j level
163 to select it). Note that you will need a restore version
164 >= 0.4b24 in order to restore a bzip2 compressed dump.
165 The same warning as for the zlib compression applies:
166 the tape format of a bzip2 dump is not compatible with the
167 original BSD tape format.
169 7. Fixed a overflow problem in dump corrupting the dump when
170 very large files were encountered. Thanks to Vladimir Nadvornik
173 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
174 kernel buffer/page cache before starting the dump, helping
175 a bit those who use dump on mounted filesystems. Thanks to
176 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
179 9. Updated the RPM spec file following the RedHat changes
180 (dynamically linked binaries now in /usr/sbin etc).
182 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
183 which enables restore to recognise multi volume compressed dumps
184 done on CD. Included his scripts for dump (which pipe the dump
185 output directly into cdrecord) and restore. There is now
186 possible to to backups to CD on the fly!
188 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
189 ===================================================================
191 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
192 Marcus Meissner (Caldera International Security Dept.).
194 2. Implement the Sun rmt extended protocol. Patch submitted
195 by Ian Gordon <iangordon@users.sourceforge.net>.
197 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
198 the linux kernel header. This ensures that dump always has the
199 latest version of this file. Patch submitted by
200 Andreas Dilger <adilger@turbolinux.com>.
202 4. Report any filesystem present in either /etc/fstab with a
203 positive passno or /etc/dumpdates in dump -w output.
204 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
206 5. Fixed the looping problem in dump introduced in the
209 6. Changed the -B option of dump to limit the size of
210 _compressed_ output per volume if compression is on.
211 Patch contributed by Helmut Jarausch
212 <jarausch@igpm.rwth-aachen.de>. Note however that, since
213 it is impossible to predict the size of the compressed
214 data before doing the compression, the -B limit is a bit
217 7. Fixed a bug in reading the operator typed file/tape path for
218 the next volume in restore.
220 8. Implemented a "-F script" option to restore which permits the
221 user to specify a script which will be launched at the
222 beginning of each tape, useful for automatic programming of
223 tape changers for example. See the restore man page for the
224 script parameters and return codes.
226 9. Small fix for the QFA routines provided by Uwe Gohlke
227 <uwe@ugsoft.de>, and some recommendations for QFA uses in
230 10. Fixed the multivolume restoring where making a mistake
231 to the 'Mount next tape' prompt caused several blocks to
234 11. Enhanced the -e option of dump to take as a parameter a
235 comma separated list of inode numbers.
237 12. Added the -E option to dump which specify a file containing
238 inode numbers to exclude from the dump.
240 13. Fixed the compressed multi-volume dump + restore.
242 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
243 ==================================================================
245 1. Made dump report the number of blocks dumped per volume.
246 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
248 2. Fix a bug in dump where waiting too much at the 'change volumes'
249 question caused the volume to be rewritten. Thanks to
250 Graham Reed <greed@users.sourceforge.net> for reporting the
251 bug and providing a patch.
253 3. Added a compression option to dump, contributed by Jerry
254 Peters <gapeters@worldnet.att.net>.
256 WARNING: the compression works only on files/pipes and
257 drives supporting variable block size.
259 WARNING2: tapes created using the compression feature are
260 incompatible with the standard dump tape format, and a
261 version of restore >= 0.4b22 will be needed for extraction.
263 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
264 architectures. Thanks to Paul Slootman <paul@debian.org> for
265 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
268 5. Many cleanups (CPP defines, const char warnings, check of
269 ext2fs COMPAT flags, time_t cleanups, added libext2 version
270 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
272 6. Made --prefix option work in configure. All the install path
273 are now based on the configure parameters.
275 7. Added the Quick File Access mode in dump/restore, contributed
276 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
277 a file tape position for each inode, and this file is used by
278 restore (if called with parameter Q and the filename)
279 to directly position the tape at the file restore is currently
280 working on. This saves hours when restoring single files from
281 large backups, saves the tapes and the drive's head. Use
282 --enable-qfa option of configure to compile in the QFA support.
284 8. Added the possibility to dump several files and directories
285 in a single invocation of dump. Thanks to Uwe Gohlke
286 <uwe@ugsoft.de> for implementing this option.
288 9. Fixed the dumping and restoring of files with holes
289 (files ending with holes didn't get dumped or restored
292 10. Fixed a socket descriptor leak in dump, which leaved opened
293 3 file descriptors per dump process (and there is one dump
296 11. Fixed dump large file system support, by explicit use of
297 open64/lseek64/etc functions (explicit use needed because
298 e2fsprogs libraries don't behave well when compiled with
299 FILE_OFFSET_BITS=64).
301 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
302 ======================================================================
304 1. Fixed some bugs in the dump -w|-W logic introduced by
305 the previous version. Thanks to Andreas Dilger
306 <adilger@turbolinux.com> for his help on this one.
308 2. Fixed again a compilation problem when using old e2fs
309 headers (filesystem label related). Thanks to many users
310 who reported this stupid error.
312 3. Fixed a build problem on old lib5 based systems dealing with
313 _PATH_MNTTAB being undefined. Thanks to John Adams
314 <johna@onevista.com> for reporting the bug.
316 4. Improved the error detection in restore when creating
317 the temporary files in TMPDIR. Now restore will corectly
318 report a 'no space left on device' error instead of
319 strange errors which could imply an archive corruption.
320 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
321 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
323 5. Added the throughput information in dump's progression
324 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
327 6. Use libext2fs's inode scanning routines, which are particularly
328 robust when dealing with errors (especially when having some
329 bad blocks on the filesystem). Many thanks to Colin
330 <colin@horizon.com> for reporting the bug, investigating
331 the issues, finding a workaround, writing the patch and
332 fully testing it... (of course, if this patch will break
333 anything, he is to blame for :-)).
335 7. Made dump and restore LFS aware. Dump can dump a filesystem
336 containing large files, generate a large file on output and
337 restore can restore them. This feature is not enabled by
338 default, use --enable-largefile option of configure to enable
339 it (you need to have a LFS aware glibc though). Thanks to
340 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
341 and to Theodore T'so <tytso@valinux.com> for his always
344 8. Made dump ask upon a tape write error if it should rewrite
345 the current volume (assume this is a bad tape) or if it should
346 assume an end-of-tape condition (useful for tape drives which
347 behaves badly at the end of the tape). Thanks to Andreas
348 Dilger <adilger@turbolinux.com> for the suggestion.
350 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
351 =======================================================================
353 1. Fixed a small compilation problem due to a change
354 in the definintion of the struct sigaction in
355 glibc 2.0 / libc5. Thanks to Gunther Schlegel
356 <schlegel@riege.de> for reporting the bug and to
357 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
360 2. Modified the label and uuid analysis in order to be
361 self-contained (independant of kernel/libc headers). This
362 should fix the compile with older kernel/libc headers and
363 will preserve the functionality. Thanks to Bernhard Erdmann
364 <bernhard.erdmann@gmx.de> for reporting the bug.
366 3. The 'exclude inode' option, if applied to a directory
367 inode, excludes now correctly all the leaves of this
368 directory. Thanks to John R. Dennison
369 <gerdesas@users.sourceforge.net> for reporting the bug.
371 4. Fixed the '-e' option to disable the possibility
372 to exclude the root inode (which causes the dumps to
373 be unreadable by restore). Prevented array overflow
374 when multiple -e options are used.
376 5. Fixed dump to correctly interpret a filesystem argument
377 which is a mountpoint and it is not an absolute path
378 (as specified in the fstab). Thanks to Bernhard R. Erdmann
379 <be@berdmann.de> for reporting the bug.
381 6. Made dump able to backup files larger than 2 GB. Note that
382 dump still doesn't cope with files larger than 4 GB.
384 7. Restore the real uid and gid before invoking an external
385 RSH program (big hole when dump or restore is suid root!).
387 8. Get the values for the default tape device and the location
388 of fstab file from the system headers. Thanks to
389 Andreas Dilger <adilger@turbolinux.com> for the patch.
391 9. Made dump -w|-W report all recognized filesystems
392 present in either /etc/fstab or /etc/dumpdates, and present
393 the list in the same order as in fstab file. Thanks
394 to Andreas Dilger <adilger@turbolinux.com> for the patch.
396 10. Made dump's -a (automatic end of tape detection) the
397 default. Specifying one of -B, -c, -d or -s options will
398 override the EOM detection. Thanks to Andreas Dilger
399 <adilger@turbolinux.com> for the patch.
401 11. Save the ext2 filesystem label into the dump volume label.
402 Specifying a volume label on the command line (-L option)
403 will override this feature. Thanks to Andreas Dilger
404 <adilger@turbolinux.com> for the patch.
406 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
407 =====================================================================
409 1. Fixed the signal handling in dump (which I broke in 0.4b17)
410 which was causing several strange dump failures (dump
411 hanged or segmentation faults etc).
413 2. Specified the default blocksize in the dump man page.
415 3. Changed two info messages of restore to be written on stdout
416 instead of stderr in order to leave stderr only for errors
417 or warnings. Thanks to Stephen Atwell
418 <satwell@urbana.css.mot.com> for the suggestion.
420 4. Corrected an off by one calculation which prevented
421 dumping a directory having a 1 character name length.
422 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
423 for reporting the bug.
425 5. Reinforce dump in order to allow only level 0 and no
426 -u option when dumping a subdirectory, and document
427 this in the man page. Thanks to Bernhard Erdmann
428 <bernhard.erdmann@gmx.de> for reporting the bug.
430 6. Fixed a small harmless bug in restore which caused
431 in some conditions hard links to be restored several
432 times (therefore generation some warning messages).
433 Thanks to Kenneth Porter <shiva@well.com> for
436 7. Updated the RPM spec file to the latest RedHat version,
437 providing FHS packaging and other cosmetic changes.
438 You will need RPM version >= 3.0.5 in order to build the RPM.
440 8. Updated the configure script to check for libtermcap
441 before checking for libreadline, because we need this
442 library in order to compile the readline support.
444 9. Made dump understand the LABEL= and UUID= notation
445 both in /etc/fstab and on the command line. Note that
446 you will need the /proc filesystem in order to use
447 these notations. Thanks to Erik Troan <ewt@redhat.com>
448 for providing the patch.
450 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
451 ===================================================================
453 1. Fixed a potential buffer overflow in restore. Thanks
454 to Stan Bubrouski <satan@fastdial.net> for reporting
457 2. Fixed a readline-related bug which prevented
458 'cat DUMPFILE | restore -i -f -' from working. Thanks
459 to Charles Karney <karney@users.sourceforge.net>
462 3. Changed a few "panic" into "exit", causing restore to
463 be more stable against some attacks (like the last one
464 reported on Bugtraq, although the last version of restore
465 was not vulnerable - just dumped core). Thanks to
466 Andreas Hasenack <andreas@conectiva.com.br> for reporting
469 4. Removed the suid-root bit on dump and restore in the
470 default build (and generated RPMs). It should be safer
471 now. Users who need the suid-root capabilities in order
472 to make network backups should read first the man page
473 of dump and enable the suid bit manually.
475 5. Added -ltermcap to the compile parameters for restore
476 when using readline support, in order to make the compile
477 process work on some systems (SuSE ?). Thanks to
478 Patrik Schindler <poc@pocnet.net> for reporting the bug.
480 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
481 ====================================================================
483 1. The -F script is called now *only* at the end of a tape,
484 not at the end of the dump. Thanks to Christian Haul
485 <haul@informatik.tu-darmstadt.de> for the bug report.
487 Normally, the device name and the current volume number
488 are passed on the command line of the script. However,
489 if you want the old style script (with no arguments
490 passed on the command line), you can enable it in
491 configure with the --enable-oldstylefscript.
493 2. Use posix signal handling to preserve dump functionality
494 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
497 3. Made the exit code of restore in case of a 'C'ompare
498 command reflect the result of the compare. An exit status
499 of 0 means the dump archive is correct, 1 means tape errors,
500 2 means that some files were modified. Thanks to Kenneth Porter
501 <shiva@well.com> for the suggestion.
503 4. Made (finally) quotes work in interactive restore.
505 5. Small fixes in order to allow dump to compile with a
506 really old e2fsprogs version. Thanks to Ian Zimmerman
507 <itz@speakeasy.org> for the bug report.
509 6. Add GNU readline capabilities to interactive restore.
510 Use configure's --enable-readline flag to enable this feature.
511 Thanks to Patrik Schindler <poc@pocnet.net> for the
514 7. Do the compare on the fly in restore 'C' mode (this will
515 allow not to exhaust the available /tmp space when
516 ccmparing large files). Thanks to Kenneth Porter
517 <shiva@well.com> for the suggestion.
519 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
520 ====================================================================
522 1. Fixed some several duplicate 'DUMP: DUMP:' in the
525 2. Corrected the estimation of blocks to dump. Note that
526 this is still wrong for large directory inodes, due
527 to the size of a BSD directory entry on the tape
528 (estimation is based on the size of the ext2 directory,
529 which is smaller because it doesn't contain the null
530 character at the end).
532 3. Made dump report the total number of MB written to
533 tape at the end of run. Thanks to W. Reilly Cooley
534 <wcooley@nakedape.cc> for the patch.
536 4. Added the -X option to restore giving the possibility
537 to read the names of the files to be extracted/listed
538 from a text file (in addition of the command line).
539 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
542 5. Added the device name and the current volume number
543 as arguments to the end of tape script (dump -F option).
545 6. Made the multi-volume dump work again (after having
546 broken it in 0.4b15).
548 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
549 ===================================================================
551 1. Added a prompt command in interactive restore mode. Thanks
552 to Andreas Dilger <adilger@home.com> for the patch.
554 2. Fixed a buffer overflow problem in dump (caused by
555 not checking the size of the filesystem parameter).
556 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
557 reporting this on Bugtraq (and to several dump users
558 who forwarded me his mail).
560 3. Added the '-F script' option to dump in order to
561 launch a script at the end of each tape (to be used
562 with a tape changer, or to notify the sysadmin by
565 4. Fixed a bug in restore compare code caused by the changes
568 5. Fixed the treatment of options using the old BSD syntax
569 in both dump and restore.
571 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
572 =======================================================================
574 1. Fixed a bug in dump which may have caused invalid deleted
575 directories to be dumped out if they were deleted after the
576 mapping pass. This could occure on active filesystem and lead
577 to heap corruption (causing dump malfunction in many possible ways).
578 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
579 bug and submitting the patch.
581 2. Fixed the handling of the filesystem parameter in dump. A
582 '/mnt/disk' parameter caused the disk contents to be dumped,
583 but a '/mnt/disk/' parameter caused the mountpoint directory
584 to be dumped (generally an empty directory).
586 3. Improved the output of dump in order to tell which directory
587 it is currently dumping (when dumping a subtree).
589 4. Added the '-e' exclude inode option to dump. Thanks to
590 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
592 5. Added a REPORTING-BUGS file in order to provide a guide
593 on how to correctly report a bug in dump/restore.
595 6. Fixed a restore problem when restoring a hard link to an inode
596 having the immutable or append-only attribute set. Thanks to
597 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
599 7. Fixed a compatibility problem between dumps made on little
600 endian machines (the format was correct) and big endian
601 machines (the format was incorrect). This fix break the
602 compatibility with the older dumps made on big endian
603 machines (sparc, m86k, ppc etc). For the first time in
604 linux dump's history (I believe), the dumps made by *BSD,
605 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
606 so interchangeable. Thanks to Rob Cermak
607 <cermak@ahab.rutgers.edu> for submitting the bug and
608 helping me test the fix.
610 8. Fixed the way dump reports the remaining percent/time, if
611 the number of blocks actually dumped exceeds the estimated
612 number of blocks. Thanks to Jean-Paul van der Jagt
613 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
615 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
616 ======================================================================
618 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
619 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
621 2. Removed the requirement to build the RPM as root from the
622 spec file. Thanks to Christian Weisgerber
623 <naddy@mips.rhein-neckar.de> for submitting this.
625 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
626 causing dump to block when dumping really huge filesystems.
627 Many thanks to Patrik Schindler <poc@pocnet.net> for
628 helping me find this bug.
630 4. Fixed the treatment for an interrupt signal when dump access
631 the remote tape through RSH. Thanks to Christian Weisgerber
632 <naddy@mips.rhein-neckar.de> for providing the patch.
634 5. Fixed a bug which was causing dump/restore to display
635 garbage characters instead of the remote host name.
637 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
638 =====================================================================
640 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
641 <kukuk@suse.de> for submitting the patch.
643 2. Fix for the exit code when using the size estimate option of
644 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
645 submitting the patch.
647 3. Handle EINTR in atomical reads/writes in dump, which was causing
648 dump to fail on some systems. Thanks to Eric Jergensen
649 <eric@dvns.com> for reporting the bug and submitting the patch.
651 4. Handle more than 16 characters for the device names in dumpdates.
652 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
653 tracking down the problem and proposing the solution.
655 5. Fixed a bug in dump which prevented the creation of the
656 dumpdates file when doing a 0-level dump without already
657 having a dumpdates file. Thanks to Patrik Schindler
658 <poc@pocnet.net> for reporting the bug.
660 6. Changed the way dump 'S' flag reports the size estimate
661 from number of blocks into bytes (making it compatible
662 with the Solaris version, and simplifying things for
663 amanda users). Thanks to Jason L Tibbitts III
664 <tibbs@math.uh.edu> for reporting the bug.
666 7. Fixed a compatibility problem in linux/alpha dump tape format.
667 Now the linux/alpha dump are (again) compatible with the
668 other dump formats. But this breaks compatibility with
669 older dumps made on alpha. Thanks to Mike Tibor
670 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
672 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
673 ======================================================================
675 1. Added a '--enable-kerberos' to configure.
677 2. Added a 'S' option to dump which determines the amount of space
678 that is needed to perform the dump without actually doing it, similar
679 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
680 <cermak@ahab.rutgers.edu>.
682 3. Added a 'M' multi-volume option to dump and restore which enables
683 dumping to multiple files (useful when dumping to an ext2
684 partition to make several dump files in order to bypass the 2GB
685 file size limitation). The 'f' argument is treated as a prefix and
686 the output files will be named <prefix>001, <prefix>002 etc. With
687 the 'M' flag, restore automatically selects the right file without
688 asking to enter a new tape each time.
690 4. Fixed a memory leak which was causing dump to grow very big
691 (270MB when dumping a 10GB filesystem...). Thanks to Jason
692 Fearon <jasonf@netrider.org.au> for reporting the bug.
694 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
695 ======================================================================
697 1. Make configure test if the system glob routines support
698 extended syntax (ALTDIRFUNC). If not, use the internal glob
699 routines instead of system ones. Thanks to Bernhard Sadlowski
700 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
701 and helping me resolve this and other minor libc5 compiling
704 2. Fix a problem when dumping a ext2fs with the 'filetype'
705 feature enabled. Thanks to Patrick J. LoPresti
706 <patl@cag.lcs.mit.edu> for reporting the bug and to
707 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
709 3. Made the nodump flag work on directories. A directory which
710 has the nodump flag gets never dumped, regardless of its
713 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
714 which allows dump on an active ext3 filesystem. However, this
715 is a "quick and dirty" patch which enables backup of an ext3
716 filesystem through the ext2 compatibility (by ignoring the
717 NEEDS_RECOVERY bit). The journal file is not recognized and
718 it is dumped (it should not).
720 5. Test the superblock compatibility flags when dumping, in order
721 to be sure that we know how to deal with specific features.
723 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
724 ====================================================================
726 1. Use lchown instead of chown, fixing a possible security problem
727 when restoring symlinks (a malicious user could use this
728 to deliberately corrupt the ownership of important system files).
729 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
730 this and providing the patch.
732 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
733 ====================================================================
735 1. Put dump sources under CVS, added Id tags in all files so
736 one can use 'ident' on binary files.
738 2. Added the dump/restore version in the usage text so one can
739 easily verify the version he is using.
741 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
742 a va_start/va_end problem on linux-ppc (always call va_start
743 va_end in pairs each time we use a vararg function).
745 4. Added again the DT_* constants because old libc does not
746 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
747 for submitting the bug report.
749 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
750 this should enable dumping big (huge) filesystems.
752 6. Added the RSH environment variable in order to be able to
753 use a rsh replacement like ssh when doing remote backups (and
754 bypass the security limitations of rcmd). Now you can do remote
755 backups without being root (or making dump setuid root).
757 7. Modified again the way dumpdates works. For incremental dumps,
758 we need to read dumpdates even if we are not using 'u' option.
759 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
762 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
763 ===================================================================
765 1. Removed the 'k' flag from the restore 'about' text if kerberos
768 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
769 to them (fsetflags takes a char*, setflags an open fd!).
771 3. (f)setflags is called only if the flags aren't empty. If the
772 file is a special file, a warning is printed, because changing
773 flags implies opening the device. Normally, a special file
774 should not have any flag... (Debian bug #29775, patch provided
775 by Abhijit Dasgupta <abhijit@ans.net>).
777 4. Made possible to dump a file system not mentioned in /etc/fstab.
778 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
780 5. Changed the default behaviour to not create dumpdates
781 unless 'u' option is specified. Removed the old "debian-patch"
782 which provided the same thing. (Debian bug #38136, #33818).
784 6. Removed all those dump*announce, since they were getting old...
786 7. Added warning messages if dumpdates does not exist and
787 when an inferior level dump does not exist (except for a level 0
790 8. Debugged the glob calls in interactive mode: restore used a
791 dirent struct which was different from the /usr/include/dirent.h
792 one (this used to work, is it a glibc2 change?), so none of the
793 compat glob (which used /usr/include/dirent.h) or the system glob
794 worked. Restore use now the system dirent (and the system
795 DT_* constants), which are compatible with BSD ones.
797 9. Added a configure flag (--with-dumpdatespath) to specify
798 the location of dumpdates file. By default, it is
801 10. Added the "AUTHOR" and "AVAILABILITY" sections and
802 included the current date/version in man pages.
804 11. Corrected the estimation of remaining time when
805 the operator doesn't change the tapes quickly enough. This
806 was an old bug, I thought I corrected it, and discovered
807 that in fact it was corrected in two different places, so
808 the results canceled each other...
810 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
811 ===================================================================
813 1. Integrated multiple patches from RedHat, Debian and SuSE:
815 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
817 - several fixes in the man pages.
818 - update the default tape device to /dev/st0.
819 - many updates for Linux Alpha (byte ordering, size_t etc).
821 - use environment variable for TMPDIR (instead of /tmp).
822 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
823 - workaround egcs bug (RedHat bugs #4281 and #2989).
824 - wire $(OPT) throughout Makefile's.
826 2. Upgrade the dump revision to 1, making possible to dump filesystems
827 made with e2fsprogs-1.15 or newer. Nothing seems to break...
829 3. Fix some compile warnings, prototype all functions.
831 4. Use glibc err/glob instead of internal compatibility
832 routines (only if available).
834 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
835 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
837 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
838 ======================================================================
840 1. Integrated the changes from FreeBSD-3.1-RELEASE
841 (mostly bug fixes, buffer overruns, dump has now an "automatic
842 tape length calculation" flag, dump/restore can use kerberos now
843 (this is NOT tested), use environment variables for TAPE and
846 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
848 3. Corrected a bug in restore when using 'C' option with multi-volumes
849 tapes (files splited accros two tapes give "size changed" errors
852 4. Corrected the long standing bug when dumping multiple tapes.
853 This works for me, needs further testing.
855 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
856 ====================================================================
858 1. Dump now runs correctly on kernels 2.1.x
859 Fix made by Gerald Peters <gapeters@worldnet.att.net>
861 Changes between versions 0.4b2 and 0.4b3
862 ========================================
864 1. Use realpath() if available
868 Changes between versions 0.4b1 and 0.4b2
869 ========================================
871 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
874 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
876 3. Fixed configure.in to correctly handle --enable-rmt
878 Changes between versions 0.3 and 0.4b1
879 ======================================
881 1. Integrated the changes from 4.4BSD-Lite2
883 2. Integrated the patches from Debian and Red Hat
885 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
887 4. Changed dump to use the Ext2fs library to get block addresses. This
888 should solve the endianness problem on SparcLinux.
890 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
891 distribution's one) to use autoconf
893 6. Fixed a few minor bugs
895 Changes between versions 0.2e and 0.2f
896 ======================================
898 1. Added the creation of named pipes (fifos) in restore.
900 2. Added the -N flag in the restore manual page.
902 3. Added the file kernel.patch which contains the llseek() optimization
903 patch for 1.2.x kernels.
905 4. Fixed a bug in the restoration of symbolic links: owner and group were
908 5. Integrated some changes from FreeBSD 2.2.
910 6. Added a call to ftruncate() after restoring each file to restore
911 correctly files ending by a hole.
913 Changes between versions 0.2d and 0.2e
914 ======================================
916 1. Fixed a bug in the "set owner/mode" process. Every file was restored
917 with owner = root (0) and group = root/wheel/whatever (0).
919 Changes between versions 0.2c and 0.2d
920 ======================================
922 1. Dump is now able to backup 2GB+ filesystems.
924 2. Dump and restore can now be linked as static binaries.
926 Changes between versions 0.2b and 0.2c
927 ======================================
929 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
931 Changes between versions 0.2a and 0.2b
932 ======================================
934 1. Really fixed the bug that I should have corrected in 0.2a.
936 2. Enabled optimization again.
938 Changes between versions 0.2 and 0.2a
939 =====================================
941 1. Disabled the optimization during compilation.
943 Changes between versions 0.1 and 0.2
944 ====================================
946 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
947 the fs_type field (actually, I modified the file fstab.c to make it
948 use the mntent functions).
950 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
951 made by dump should be readable by the BSD restore and backups made
952 by the BSD dump should be readable by restore. Unfortunately, this
953 means that the dump format has changed between version 0.1 and version
956 3. Dump is now able to backup a subtree, it is no longer limited to whole
957 filesystems like the BSD version.
959 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
962 Changes between versions 0.0 and 0.1
963 ====================================
965 1. Now create links rdump and rrestore during the `make install' step.
967 2. Linux port specific bugs added to the manual pages
969 3. Incorrect estimation of the number of tapes blocks fixed when doing
972 4. Better ls-like format in restore in interactive mode.
