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 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
32 =======================================================================
34 1. Fixed behaviour of dump when exceeding resource limits
37 2. Added the -L flag to restore to allow the user to specify a
38 maximal allowed number of miscompares when using restore
39 with the -C option to check the backup.
41 3. Detailed the manual entry for the -N option of restore.
43 4. Added the -a flag to restore to make able doing unattended
44 restores in -i or -x mode (automatically walks through the
45 multiple dump volumes).
47 5. Extended the QFA mode to work with local files and/or
48 remote tapes and files. This way, restore can know in advance
49 the tape number and the offset for the inodes to extract and
50 can minimize the extraction time by seeking directly to the
53 6. Added the -A <archive> option to both dump and restore,
54 which makes dump to archive a dump table-of-contents in
55 the specified file to be used by restore to determine
56 whether a file is in the dump file that is being restored.
57 (the archive file syntax is also compatible with the
58 Solaris ufsdump generated one).
60 7. Small fix in restore making it able to read some (broken ?)
61 Solaris ufsdump tapes.
63 8. Fixed dump to correctly recognise the root filesystem when using
64 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
65 for reporting this bug.
67 9. Added the -P <file> option to restore to create a
68 Quick File Access file from an already made dump. Patch
69 contributed by Uwe Gohlke <uwe@ugsoft.de>.
71 10. Made restore compile and run on Solaris, making it a
72 possible replacement for the standard ufsrestore. Port was
73 contributed by Uwe Gohlke <uwe@ugsoft.de>.
75 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
76 =====================================================================
78 1. Added a set of backup scripts from Eugenio Diaz
79 <getnito@yahoo.com> in the examples section. It features
80 automatic (cron based) full and incremental dumping of
81 several filesystems on a separate filesystem.
83 2. Fixed a off-by-one miscalculation which disabled dumping
84 a one letter subdirectory. Thanks to Chris Siebenmann
85 <cks@utcc.utoronto.ca> for reporting the bug.
87 3. Fixed several restore bugs occuring when trying to
88 restore some missing files on the tape. Thanks to Chris
89 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
91 4. Fixed --with-ldopts configure argument passing, installing from
92 a separate object directory, makefile cleanups contributed
93 by <splite@purdue.edu>.
95 5. Fix a bug which could caused, in some conditions, the highest
96 number inode of a filesystem, to not be dumped. Many thanks
97 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
100 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
101 =======================================================================
103 1. Added a mini howto from Patrick Walsh in the examples
106 2. Minor man pages syntax corrections. Thanks to
107 Chris Danis <screechco@home.com> for reporting the bugs.
109 3. Added a script from David B. Peterson <dave@toppledwagon.com>
110 to the examples section. It features dumping several
111 filesystems to a remote tape drive upon ssh.
113 4. Added a patch provided by Richard Jones <rich@annexia.org>
114 which allows BRADEMAX (number of read errors tolerated by
115 dump) to be adjusted using the -I option.
117 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
118 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
121 6. Add the -l option to restore to specify if, when doing a
122 remote restore, the file used to access the backup is a
123 regular file (the defaults being a tape drive). Restore needs
124 to know this information when reading a remote compressed
125 dump. Previously, this information was autodetected, but
126 the autodetection code fails (with ioctl: Inappropriate ioctl
127 for device) when using a non Linux remote box. Thanks to
128 many users and especially to Eros Albertazzi
129 <eros@lamel.bo.cnr.it> for reporting this.
131 7. Found a workaroung for the dump deadlock problem (3 childs
132 stuck in pause(), father in read()). The workaround seems
133 to work for me and several beta-testers. If it doesn't work
134 for you, please report back.
136 8. Updated the RPM spec file (BuildPrereq, URL etc).
138 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
139 ========================================================================
141 1. Fixed the permissions of a newly created QFA file by dump.
143 2. Cleaned up the source of dump (the external variables
144 definition was a complete mess, making possible to have
147 3. Fixed restore to use the full tape volume path when doing
148 a compare (since it changes the working directory to the
149 filesystem being compared in the process).
151 4. Added the -q option to dump which makes dump abort
152 whenever it needs operator attention. It should be
153 easier to use dump in scripts with this option.
155 5. Detect the use of incompatible options to dump and
156 refuse them (like -a and -B options together).
158 6. Added bzip2 compression to dump/restore (use option -j level
159 to select it). Note that you will need a restore version
160 >= 0.4b24 in order to restore a bzip2 compressed dump.
161 The same warning as for the zlib compression applies:
162 the tape format of a bzip2 dump is not compatible with the
163 original BSD tape format.
165 7. Fixed a overflow problem in dump corrupting the dump when
166 very large files were encountered. Thanks to Vladimir Nadvornik
169 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
170 kernel buffer/page cache before starting the dump, helping
171 a bit those who use dump on mounted filesystems. Thanks to
172 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
175 9. Updated the RPM spec file following the RedHat changes
176 (dynamically linked binaries now in /usr/sbin etc).
178 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
179 which enables restore to recognise multi volume compressed dumps
180 done on CD. Included his scripts for dump (which pipe the dump
181 output directly into cdrecord) and restore. There is now
182 possible to to backups to CD on the fly!
184 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
185 ===================================================================
187 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
188 Marcus Meissner (Caldera International Security Dept.).
190 2. Implement the Sun rmt extended protocol. Patch submitted
191 by Ian Gordon <iangordon@users.sourceforge.net>.
193 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
194 the linux kernel header. This ensures that dump always has the
195 latest version of this file. Patch submitted by
196 Andreas Dilger <adilger@turbolinux.com>.
198 4. Report any filesystem present in either /etc/fstab with a
199 positive passno or /etc/dumpdates in dump -w output.
200 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
202 5. Fixed the looping problem in dump introduced in the
205 6. Changed the -B option of dump to limit the size of
206 _compressed_ output per volume if compression is on.
207 Patch contributed by Helmut Jarausch
208 <jarausch@igpm.rwth-aachen.de>. Note however that, since
209 it is impossible to predict the size of the compressed
210 data before doing the compression, the -B limit is a bit
213 7. Fixed a bug in reading the operator typed file/tape path for
214 the next volume in restore.
216 8. Implemented a "-F script" option to restore which permits the
217 user to specify a script which will be launched at the
218 beginning of each tape, useful for automatic programming of
219 tape changers for example. See the restore man page for the
220 script parameters and return codes.
222 9. Small fix for the QFA routines provided by Uwe Gohlke
223 <uwe@ugsoft.de>, and some recommendations for QFA uses in
226 10. Fixed the multivolume restoring where making a mistake
227 to the 'Mount next tape' prompt caused several blocks to
230 11. Enhanced the -e option of dump to take as a parameter a
231 comma separated list of inode numbers.
233 12. Added the -E option to dump which specify a file containing
234 inode numbers to exclude from the dump.
236 13. Fixed the compressed multi-volume dump + restore.
238 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
239 ==================================================================
241 1. Made dump report the number of blocks dumped per volume.
242 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
244 2. Fix a bug in dump where waiting too much at the 'change volumes'
245 question caused the volume to be rewritten. Thanks to
246 Graham Reed <greed@users.sourceforge.net> for reporting the
247 bug and providing a patch.
249 3. Added a compression option to dump, contributed by Jerry
250 Peters <gapeters@worldnet.att.net>.
252 WARNING: the compression works only on files/pipes and
253 drives supporting variable block size.
255 WARNING2: tapes created using the compression feature are
256 incompatible with the standard dump tape format, and a
257 version of restore >= 0.4b22 will be needed for extraction.
259 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
260 architectures. Thanks to Paul Slootman <paul@debian.org> for
261 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
264 5. Many cleanups (CPP defines, const char warnings, check of
265 ext2fs COMPAT flags, time_t cleanups, added libext2 version
266 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
268 6. Made --prefix option work in configure. All the install path
269 are now based on the configure parameters.
271 7. Added the Quick File Access mode in dump/restore, contributed
272 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
273 a file tape position for each inode, and this file is used by
274 restore (if called with parameter Q and the filename)
275 to directly position the tape at the file restore is currently
276 working on. This saves hours when restoring single files from
277 large backups, saves the tapes and the drive's head. Use
278 --enable-qfa option of configure to compile in the QFA support.
280 8. Added the possibility to dump several files and directories
281 in a single invocation of dump. Thanks to Uwe Gohlke
282 <uwe@ugsoft.de> for implementing this option.
284 9. Fixed the dumping and restoring of files with holes
285 (files ending with holes didn't get dumped or restored
288 10. Fixed a socket descriptor leak in dump, which leaved opened
289 3 file descriptors per dump process (and there is one dump
292 11. Fixed dump large file system support, by explicit use of
293 open64/lseek64/etc functions (explicit use needed because
294 e2fsprogs libraries don't behave well when compiled with
295 FILE_OFFSET_BITS=64).
297 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
298 ======================================================================
300 1. Fixed some bugs in the dump -w|-W logic introduced by
301 the previous version. Thanks to Andreas Dilger
302 <adilger@turbolinux.com> for his help on this one.
304 2. Fixed again a compilation problem when using old e2fs
305 headers (filesystem label related). Thanks to many users
306 who reported this stupid error.
308 3. Fixed a build problem on old lib5 based systems dealing with
309 _PATH_MNTTAB being undefined. Thanks to John Adams
310 <johna@onevista.com> for reporting the bug.
312 4. Improved the error detection in restore when creating
313 the temporary files in TMPDIR. Now restore will corectly
314 report a 'no space left on device' error instead of
315 strange errors which could imply an archive corruption.
316 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
317 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
319 5. Added the throughput information in dump's progression
320 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
323 6. Use libext2fs's inode scanning routines, which are particularly
324 robust when dealing with errors (especially when having some
325 bad blocks on the filesystem). Many thanks to Colin
326 <colin@horizon.com> for reporting the bug, investigating
327 the issues, finding a workaround, writing the patch and
328 fully testing it... (of course, if this patch will break
329 anything, he is to blame for :-)).
331 7. Made dump and restore LFS aware. Dump can dump a filesystem
332 containing large files, generate a large file on output and
333 restore can restore them. This feature is not enabled by
334 default, use --enable-largefile option of configure to enable
335 it (you need to have a LFS aware glibc though). Thanks to
336 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
337 and to Theodore T'so <tytso@valinux.com> for his always
340 8. Made dump ask upon a tape write error if it should rewrite
341 the current volume (assume this is a bad tape) or if it should
342 assume an end-of-tape condition (useful for tape drives which
343 behaves badly at the end of the tape). Thanks to Andreas
344 Dilger <adilger@turbolinux.com> for the suggestion.
346 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
347 =======================================================================
349 1. Fixed a small compilation problem due to a change
350 in the definintion of the struct sigaction in
351 glibc 2.0 / libc5. Thanks to Gunther Schlegel
352 <schlegel@riege.de> for reporting the bug and to
353 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
356 2. Modified the label and uuid analysis in order to be
357 self-contained (independant of kernel/libc headers). This
358 should fix the compile with older kernel/libc headers and
359 will preserve the functionality. Thanks to Bernhard Erdmann
360 <bernhard.erdmann@gmx.de> for reporting the bug.
362 3. The 'exclude inode' option, if applied to a directory
363 inode, excludes now correctly all the leaves of this
364 directory. Thanks to John R. Dennison
365 <gerdesas@users.sourceforge.net> for reporting the bug.
367 4. Fixed the '-e' option to disable the possibility
368 to exclude the root inode (which causes the dumps to
369 be unreadable by restore). Prevented array overflow
370 when multiple -e options are used.
372 5. Fixed dump to correctly interpret a filesystem argument
373 which is a mountpoint and it is not an absolute path
374 (as specified in the fstab). Thanks to Bernhard R. Erdmann
375 <be@berdmann.de> for reporting the bug.
377 6. Made dump able to backup files larger than 2 GB. Note that
378 dump still doesn't cope with files larger than 4 GB.
380 7. Restore the real uid and gid before invoking an external
381 RSH program (big hole when dump or restore is suid root!).
383 8. Get the values for the default tape device and the location
384 of fstab file from the system headers. Thanks to
385 Andreas Dilger <adilger@turbolinux.com> for the patch.
387 9. Made dump -w|-W report all recognized filesystems
388 present in either /etc/fstab or /etc/dumpdates, and present
389 the list in the same order as in fstab file. Thanks
390 to Andreas Dilger <adilger@turbolinux.com> for the patch.
392 10. Made dump's -a (automatic end of tape detection) the
393 default. Specifying one of -B, -c, -d or -s options will
394 override the EOM detection. Thanks to Andreas Dilger
395 <adilger@turbolinux.com> for the patch.
397 11. Save the ext2 filesystem label into the dump volume label.
398 Specifying a volume label on the command line (-L option)
399 will override this feature. Thanks to Andreas Dilger
400 <adilger@turbolinux.com> for the patch.
402 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
403 =====================================================================
405 1. Fixed the signal handling in dump (which I broke in 0.4b17)
406 which was causing several strange dump failures (dump
407 hanged or segmentation faults etc).
409 2. Specified the default blocksize in the dump man page.
411 3. Changed two info messages of restore to be written on stdout
412 instead of stderr in order to leave stderr only for errors
413 or warnings. Thanks to Stephen Atwell
414 <satwell@urbana.css.mot.com> for the suggestion.
416 4. Corrected an off by one calculation which prevented
417 dumping a directory having a 1 character name length.
418 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
419 for reporting the bug.
421 5. Reinforce dump in order to allow only level 0 and no
422 -u option when dumping a subdirectory, and document
423 this in the man page. Thanks to Bernhard Erdmann
424 <bernhard.erdmann@gmx.de> for reporting the bug.
426 6. Fixed a small harmless bug in restore which caused
427 in some conditions hard links to be restored several
428 times (therefore generation some warning messages).
429 Thanks to Kenneth Porter <shiva@well.com> for
432 7. Updated the RPM spec file to the latest RedHat version,
433 providing FHS packaging and other cosmetic changes.
434 You will need RPM version >= 3.0.5 in order to build the RPM.
436 8. Updated the configure script to check for libtermcap
437 before checking for libreadline, because we need this
438 library in order to compile the readline support.
440 9. Made dump understand the LABEL= and UUID= notation
441 both in /etc/fstab and on the command line. Note that
442 you will need the /proc filesystem in order to use
443 these notations. Thanks to Erik Troan <ewt@redhat.com>
444 for providing the patch.
446 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
447 ===================================================================
449 1. Fixed a potential buffer overflow in restore. Thanks
450 to Stan Bubrouski <satan@fastdial.net> for reporting
453 2. Fixed a readline-related bug which prevented
454 'cat DUMPFILE | restore -i -f -' from working. Thanks
455 to Charles Karney <karney@users.sourceforge.net>
458 3. Changed a few "panic" into "exit", causing restore to
459 be more stable against some attacks (like the last one
460 reported on Bugtraq, although the last version of restore
461 was not vulnerable - just dumped core). Thanks to
462 Andreas Hasenack <andreas@conectiva.com.br> for reporting
465 4. Removed the suid-root bit on dump and restore in the
466 default build (and generated RPMs). It should be safer
467 now. Users who need the suid-root capabilities in order
468 to make network backups should read first the man page
469 of dump and enable the suid bit manually.
471 5. Added -ltermcap to the compile parameters for restore
472 when using readline support, in order to make the compile
473 process work on some systems (SuSE ?). Thanks to
474 Patrik Schindler <poc@pocnet.net> for reporting the bug.
476 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
477 ====================================================================
479 1. The -F script is called now *only* at the end of a tape,
480 not at the end of the dump. Thanks to Christian Haul
481 <haul@informatik.tu-darmstadt.de> for the bug report.
483 Normally, the device name and the current volume number
484 are passed on the command line of the script. However,
485 if you want the old style script (with no arguments
486 passed on the command line), you can enable it in
487 configure with the --enable-oldstylefscript.
489 2. Use posix signal handling to preserve dump functionality
490 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
493 3. Made the exit code of restore in case of a 'C'ompare
494 command reflect the result of the compare. An exit status
495 of 0 means the dump archive is correct, 1 means tape errors,
496 2 means that some files were modified. Thanks to Kenneth Porter
497 <shiva@well.com> for the suggestion.
499 4. Made (finally) quotes work in interactive restore.
501 5. Small fixes in order to allow dump to compile with a
502 really old e2fsprogs version. Thanks to Ian Zimmerman
503 <itz@speakeasy.org> for the bug report.
505 6. Add GNU readline capabilities to interactive restore.
506 Use configure's --enable-readline flag to enable this feature.
507 Thanks to Patrik Schindler <poc@pocnet.net> for the
510 7. Do the compare on the fly in restore 'C' mode (this will
511 allow not to exhaust the available /tmp space when
512 ccmparing large files). Thanks to Kenneth Porter
513 <shiva@well.com> for the suggestion.
515 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
516 ====================================================================
518 1. Fixed some several duplicate 'DUMP: DUMP:' in the
521 2. Corrected the estimation of blocks to dump. Note that
522 this is still wrong for large directory inodes, due
523 to the size of a BSD directory entry on the tape
524 (estimation is based on the size of the ext2 directory,
525 which is smaller because it doesn't contain the null
526 character at the end).
528 3. Made dump report the total number of MB written to
529 tape at the end of run. Thanks to W. Reilly Cooley
530 <wcooley@nakedape.cc> for the patch.
532 4. Added the -X option to restore giving the possibility
533 to read the names of the files to be extracted/listed
534 from a text file (in addition of the command line).
535 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
538 5. Added the device name and the current volume number
539 as arguments to the end of tape script (dump -F option).
541 6. Made the multi-volume dump work again (after having
542 broken it in 0.4b15).
544 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
545 ===================================================================
547 1. Added a prompt command in interactive restore mode. Thanks
548 to Andreas Dilger <adilger@home.com> for the patch.
550 2. Fixed a buffer overflow problem in dump (caused by
551 not checking the size of the filesystem parameter).
552 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
553 reporting this on Bugtraq (and to several dump users
554 who forwarded me his mail).
556 3. Added the '-F script' option to dump in order to
557 launch a script at the end of each tape (to be used
558 with a tape changer, or to notify the sysadmin by
561 4. Fixed a bug in restore compare code caused by the changes
564 5. Fixed the treatment of options using the old BSD syntax
565 in both dump and restore.
567 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
568 =======================================================================
570 1. Fixed a bug in dump which may have caused invalid deleted
571 directories to be dumped out if they were deleted after the
572 mapping pass. This could occure on active filesystem and lead
573 to heap corruption (causing dump malfunction in many possible ways).
574 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
575 bug and submitting the patch.
577 2. Fixed the handling of the filesystem parameter in dump. A
578 '/mnt/disk' parameter caused the disk contents to be dumped,
579 but a '/mnt/disk/' parameter caused the mountpoint directory
580 to be dumped (generally an empty directory).
582 3. Improved the output of dump in order to tell which directory
583 it is currently dumping (when dumping a subtree).
585 4. Added the '-e' exclude inode option to dump. Thanks to
586 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
588 5. Added a REPORTING-BUGS file in order to provide a guide
589 on how to correctly report a bug in dump/restore.
591 6. Fixed a restore problem when restoring a hard link to an inode
592 having the immutable or append-only attribute set. Thanks to
593 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
595 7. Fixed a compatibility problem between dumps made on little
596 endian machines (the format was correct) and big endian
597 machines (the format was incorrect). This fix break the
598 compatibility with the older dumps made on big endian
599 machines (sparc, m86k, ppc etc). For the first time in
600 linux dump's history (I believe), the dumps made by *BSD,
601 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
602 so interchangeable. Thanks to Rob Cermak
603 <cermak@ahab.rutgers.edu> for submitting the bug and
604 helping me test the fix.
606 8. Fixed the way dump reports the remaining percent/time, if
607 the number of blocks actually dumped exceeds the estimated
608 number of blocks. Thanks to Jean-Paul van der Jagt
609 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
611 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
612 ======================================================================
614 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
615 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
617 2. Removed the requirement to build the RPM as root from the
618 spec file. Thanks to Christian Weisgerber
619 <naddy@mips.rhein-neckar.de> for submitting this.
621 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
622 causing dump to block when dumping really huge filesystems.
623 Many thanks to Patrik Schindler <poc@pocnet.net> for
624 helping me find this bug.
626 4. Fixed the treatment for an interrupt signal when dump access
627 the remote tape through RSH. Thanks to Christian Weisgerber
628 <naddy@mips.rhein-neckar.de> for providing the patch.
630 5. Fixed a bug which was causing dump/restore to display
631 garbage characters instead of the remote host name.
633 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
634 =====================================================================
636 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
637 <kukuk@suse.de> for submitting the patch.
639 2. Fix for the exit code when using the size estimate option of
640 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
641 submitting the patch.
643 3. Handle EINTR in atomical reads/writes in dump, which was causing
644 dump to fail on some systems. Thanks to Eric Jergensen
645 <eric@dvns.com> for reporting the bug and submitting the patch.
647 4. Handle more than 16 characters for the device names in dumpdates.
648 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
649 tracking down the problem and proposing the solution.
651 5. Fixed a bug in dump which prevented the creation of the
652 dumpdates file when doing a 0-level dump without already
653 having a dumpdates file. Thanks to Patrik Schindler
654 <poc@pocnet.net> for reporting the bug.
656 6. Changed the way dump 'S' flag reports the size estimate
657 from number of blocks into bytes (making it compatible
658 with the Solaris version, and simplifying things for
659 amanda users). Thanks to Jason L Tibbitts III
660 <tibbs@math.uh.edu> for reporting the bug.
662 7. Fixed a compatibility problem in linux/alpha dump tape format.
663 Now the linux/alpha dump are (again) compatible with the
664 other dump formats. But this breaks compatibility with
665 older dumps made on alpha. Thanks to Mike Tibor
666 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
668 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
669 ======================================================================
671 1. Added a '--enable-kerberos' to configure.
673 2. Added a 'S' option to dump which determines the amount of space
674 that is needed to perform the dump without actually doing it, similar
675 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
676 <cermak@ahab.rutgers.edu>.
678 3. Added a 'M' multi-volume option to dump and restore which enables
679 dumping to multiple files (useful when dumping to an ext2
680 partition to make several dump files in order to bypass the 2GB
681 file size limitation). The 'f' argument is treated as a prefix and
682 the output files will be named <prefix>001, <prefix>002 etc. With
683 the 'M' flag, restore automatically selects the right file without
684 asking to enter a new tape each time.
686 4. Fixed a memory leak which was causing dump to grow very big
687 (270MB when dumping a 10GB filesystem...). Thanks to Jason
688 Fearon <jasonf@netrider.org.au> for reporting the bug.
690 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
691 ======================================================================
693 1. Make configure test if the system glob routines support
694 extended syntax (ALTDIRFUNC). If not, use the internal glob
695 routines instead of system ones. Thanks to Bernhard Sadlowski
696 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
697 and helping me resolve this and other minor libc5 compiling
700 2. Fix a problem when dumping a ext2fs with the 'filetype'
701 feature enabled. Thanks to Patrick J. LoPresti
702 <patl@cag.lcs.mit.edu> for reporting the bug and to
703 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
705 3. Made the nodump flag work on directories. A directory which
706 has the nodump flag gets never dumped, regardless of its
709 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
710 which allows dump on an active ext3 filesystem. However, this
711 is a "quick and dirty" patch which enables backup of an ext3
712 filesystem through the ext2 compatibility (by ignoring the
713 NEEDS_RECOVERY bit). The journal file is not recognized and
714 it is dumped (it should not).
716 5. Test the superblock compatibility flags when dumping, in order
717 to be sure that we know how to deal with specific features.
719 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
720 ====================================================================
722 1. Use lchown instead of chown, fixing a possible security problem
723 when restoring symlinks (a malicious user could use this
724 to deliberately corrupt the ownership of important system files).
725 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
726 this and providing the patch.
728 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
729 ====================================================================
731 1. Put dump sources under CVS, added Id tags in all files so
732 one can use 'ident' on binary files.
734 2. Added the dump/restore version in the usage text so one can
735 easily verify the version he is using.
737 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
738 a va_start/va_end problem on linux-ppc (always call va_start
739 va_end in pairs each time we use a vararg function).
741 4. Added again the DT_* constants because old libc does not
742 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
743 for submitting the bug report.
745 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
746 this should enable dumping big (huge) filesystems.
748 6. Added the RSH environment variable in order to be able to
749 use a rsh replacement like ssh when doing remote backups (and
750 bypass the security limitations of rcmd). Now you can do remote
751 backups without being root (or making dump setuid root).
753 7. Modified again the way dumpdates works. For incremental dumps,
754 we need to read dumpdates even if we are not using 'u' option.
755 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
758 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
759 ===================================================================
761 1. Removed the 'k' flag from the restore 'about' text if kerberos
764 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
765 to them (fsetflags takes a char*, setflags an open fd!).
767 3. (f)setflags is called only if the flags aren't empty. If the
768 file is a special file, a warning is printed, because changing
769 flags implies opening the device. Normally, a special file
770 should not have any flag... (Debian bug #29775, patch provided
771 by Abhijit Dasgupta <abhijit@ans.net>).
773 4. Made possible to dump a file system not mentioned in /etc/fstab.
774 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
776 5. Changed the default behaviour to not create dumpdates
777 unless 'u' option is specified. Removed the old "debian-patch"
778 which provided the same thing. (Debian bug #38136, #33818).
780 6. Removed all those dump*announce, since they were getting old...
782 7. Added warning messages if dumpdates does not exist and
783 when an inferior level dump does not exist (except for a level 0
786 8. Debugged the glob calls in interactive mode: restore used a
787 dirent struct which was different from the /usr/include/dirent.h
788 one (this used to work, is it a glibc2 change?), so none of the
789 compat glob (which used /usr/include/dirent.h) or the system glob
790 worked. Restore use now the system dirent (and the system
791 DT_* constants), which are compatible with BSD ones.
793 9. Added a configure flag (--with-dumpdatespath) to specify
794 the location of dumpdates file. By default, it is
797 10. Added the "AUTHOR" and "AVAILABILITY" sections and
798 included the current date/version in man pages.
800 11. Corrected the estimation of remaining time when
801 the operator doesn't change the tapes quickly enough. This
802 was an old bug, I thought I corrected it, and discovered
803 that in fact it was corrected in two different places, so
804 the results canceled each other...
806 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
807 ===================================================================
809 1. Integrated multiple patches from RedHat, Debian and SuSE:
811 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
813 - several fixes in the man pages.
814 - update the default tape device to /dev/st0.
815 - many updates for Linux Alpha (byte ordering, size_t etc).
817 - use environment variable for TMPDIR (instead of /tmp).
818 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
819 - workaround egcs bug (RedHat bugs #4281 and #2989).
820 - wire $(OPT) throughout Makefile's.
822 2. Upgrade the dump revision to 1, making possible to dump filesystems
823 made with e2fsprogs-1.15 or newer. Nothing seems to break...
825 3. Fix some compile warnings, prototype all functions.
827 4. Use glibc err/glob instead of internal compatibility
828 routines (only if available).
830 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
831 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
833 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
834 ======================================================================
836 1. Integrated the changes from FreeBSD-3.1-RELEASE
837 (mostly bug fixes, buffer overruns, dump has now an "automatic
838 tape length calculation" flag, dump/restore can use kerberos now
839 (this is NOT tested), use environment variables for TAPE and
842 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
844 3. Corrected a bug in restore when using 'C' option with multi-volumes
845 tapes (files splited accros two tapes give "size changed" errors
848 4. Corrected the long standing bug when dumping multiple tapes.
849 This works for me, needs further testing.
851 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
852 ====================================================================
854 1. Dump now runs correctly on kernels 2.1.x
855 Fix made by Gerald Peters <gapeters@worldnet.att.net>
857 Changes between versions 0.4b2 and 0.4b3
858 ========================================
860 1. Use realpath() if available
864 Changes between versions 0.4b1 and 0.4b2
865 ========================================
867 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
870 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
872 3. Fixed configure.in to correctly handle --enable-rmt
874 Changes between versions 0.3 and 0.4b1
875 ======================================
877 1. Integrated the changes from 4.4BSD-Lite2
879 2. Integrated the patches from Debian and Red Hat
881 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
883 4. Changed dump to use the Ext2fs library to get block addresses. This
884 should solve the endianness problem on SparcLinux.
886 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
887 distribution's one) to use autoconf
889 6. Fixed a few minor bugs
891 Changes between versions 0.2e and 0.2f
892 ======================================
894 1. Added the creation of named pipes (fifos) in restore.
896 2. Added the -N flag in the restore manual page.
898 3. Added the file kernel.patch which contains the llseek() optimization
899 patch for 1.2.x kernels.
901 4. Fixed a bug in the restoration of symbolic links: owner and group were
904 5. Integrated some changes from FreeBSD 2.2.
906 6. Added a call to ftruncate() after restoring each file to restore
907 correctly files ending by a hole.
909 Changes between versions 0.2d and 0.2e
910 ======================================
912 1. Fixed a bug in the "set owner/mode" process. Every file was restored
913 with owner = root (0) and group = root/wheel/whatever (0).
915 Changes between versions 0.2c and 0.2d
916 ======================================
918 1. Dump is now able to backup 2GB+ filesystems.
920 2. Dump and restore can now be linked as static binaries.
922 Changes between versions 0.2b and 0.2c
923 ======================================
925 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
927 Changes between versions 0.2a and 0.2b
928 ======================================
930 1. Really fixed the bug that I should have corrected in 0.2a.
932 2. Enabled optimization again.
934 Changes between versions 0.2 and 0.2a
935 =====================================
937 1. Disabled the optimization during compilation.
939 Changes between versions 0.1 and 0.2
940 ====================================
942 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
943 the fs_type field (actually, I modified the file fstab.c to make it
944 use the mntent functions).
946 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
947 made by dump should be readable by the BSD restore and backups made
948 by the BSD dump should be readable by restore. Unfortunately, this
949 means that the dump format has changed between version 0.1 and version
952 3. Dump is now able to backup a subtree, it is no longer limited to whole
953 filesystems like the BSD version.
955 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
958 Changes between versions 0.0 and 0.1
959 ====================================
961 1. Now create links rdump and rrestore during the `make install' step.
963 2. Linux port specific bugs added to the manual pages
965 3. Incorrect estimation of the number of tapes blocks fixed when doing
968 4. Better ls-like format in restore in interactive mode.
