3 Changes between versions 0.4b25 and 0.4b26 (released ?????????????????)
4 =======================================================================
6 1. Added a set of backup scripts from Eugenio Diaz
7 <getnito@yahoo.com> in the examples section. It features
8 automatic (cron based) full and incremental dumping of
9 several filesystems on a separate filesystem.
11 2. Fixed a off-by-one miscalculation which disabled dumping
12 a one letter subdirectory. Thanks to Chris Siebenmann
13 <cks@utcc.utoronto.ca> for reporting the bug.
15 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
16 =======================================================================
18 1. Added a mini howto from Patrick Walsh in the examples
21 2. Minor man pages syntax corrections. Thanks to
22 Chris Danis <screechco@home.com> for reporting the bugs.
24 3. Added a script from David B. Peterson <dave@toppledwagon.com>
25 to the examples section. It features dumping several
26 filesystems to a remote tape drive upon ssh.
28 4. Added a patch provided by Richard Jones <rich@annexia.org>
29 which allows BRADEMAX (number of read errors tolerated by
30 dump) to be adjusted using the -I option.
32 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
33 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
36 6. Add the -l option to restore to specify if, when doing a
37 remote restore, the file used to access the backup is a
38 regular file (the defaults being a tape drive). Restore needs
39 to know this information when reading a remote compressed
40 dump. Previously, this information was autodetected, but
41 the autodetection code fails (with ioctl: Inappropriate ioctl
42 for device) when using a non Linux remote box. Thanks to
43 many users and especially to Eros Albertazzi
44 <eros@lamel.bo.cnr.it> for reporting this.
46 7. Found a workaroung for the dump deadlock problem (3 childs
47 stuck in pause(), father in read()). The workaround seems
48 to work for me and several beta-testers. If it doesn't work
49 for you, please report back.
51 8. Updated the RPM spec file (BuildPrereq, URL etc).
53 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
54 ========================================================================
56 1. Fixed the permissions of a newly created QFA file by dump.
58 2. Cleaned up the source of dump (the external variables
59 definition was a complete mess, making possible to have
62 3. Fixed restore to use the full tape volume path when doing
63 a compare (since it changes the working directory to the
64 filesystem being compared in the process).
66 4. Added the -q option to dump which makes dump abort
67 whenever it needs operator attention. It should be
68 easier to use dump in scripts with this option.
70 5. Detect the use of incompatible options to dump and
71 refuse them (like -a and -B options together).
73 6. Added bzip2 compression to dump/restore (use option -j level
74 to select it). Note that you will need a restore version
75 >= 0.4b24 in order to restore a bzip2 compressed dump.
76 The same warning as for the zlib compression applies:
77 the tape format of a bzip2 dump is not compatible with the
78 original BSD tape format.
80 7. Fixed a overflow problem in dump corrupting the dump when
81 very large files were encountered. Thanks to Vladimir Nadvornik
84 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
85 kernel buffer/page cache before starting the dump, helping
86 a bit those who use dump on mounted filesystems. Thanks to
87 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
90 9. Updated the RPM spec file following the RedHat changes
91 (dynamically linked binaries now in /usr/sbin etc).
93 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
94 which enables restore to recognise multi volume compressed dumps
95 done on CD. Included his scripts for dump (which pipe the dump
96 output directly into cdrecord) and restore. There is now
97 possible to to backups to CD on the fly!
99 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
100 ===================================================================
102 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
103 Marcus Meissner (Caldera International Security Dept.).
105 2. Implement the Sun rmt extended protocol. Patch submitted
106 by Ian Gordon <iangordon@users.sourceforge.net>.
108 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
109 the linux kernel header. This ensures that dump always has the
110 latest version of this file. Patch submitted by
111 Andreas Dilger <adilger@turbolinux.com>.
113 4. Report any filesystem present in either /etc/fstab with a
114 positive passno or /etc/dumpdates in dump -w output.
115 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
117 5. Fixed the looping problem in dump introduced in the
120 6. Changed the -B option of dump to limit the size of
121 _compressed_ output per volume if compression is on.
122 Patch contributed by Helmut Jarausch
123 <jarausch@igpm.rwth-aachen.de>. Note however that, since
124 it is impossible to predict the size of the compressed
125 data before doing the compression, the -B limit is a bit
128 7. Fixed a bug in reading the operator typed file/tape path for
129 the next volume in restore.
131 8. Implemented a "-F script" option to restore which permits the
132 user to specify a script which will be launched at the
133 beginning of each tape, useful for automatic programming of
134 tape changers for example. See the restore man page for the
135 script parameters and return codes.
137 9. Small fix for the QFA routines provided by Uwe Gohlke
138 <uwe@ugsoft.de>, and some recommendations for QFA uses in
141 10. Fixed the multivolume restoring where making a mistake
142 to the 'Mount next tape' prompt caused several blocks to
145 11. Enhanced the -e option of dump to take as a parameter a
146 comma separated list of inode numbers.
148 12. Added the -E option to dump which specify a file containing
149 inode numbers to exclude from the dump.
151 13. Fixed the compressed multi-volume dump + restore.
153 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
154 ==================================================================
156 1. Made dump report the number of blocks dumped per volume.
157 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
159 2. Fix a bug in dump where waiting too much at the 'change volumes'
160 question caused the volume to be rewritten. Thanks to
161 Graham Reed <greed@users.sourceforge.net> for reporting the
162 bug and providing a patch.
164 3. Added a compression option to dump, contributed by Jerry
165 Peters <gapeters@worldnet.att.net>.
167 WARNING: the compression works only on files/pipes and
168 drives supporting variable block size.
170 WARNING2: tapes created using the compression feature are
171 incompatible with the standard dump tape format, and a
172 version of restore >= 0.4b22 will be needed for extraction.
174 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
175 architectures. Thanks to Paul Slootman <paul@debian.org> for
176 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
179 5. Many cleanups (CPP defines, const char warnings, check of
180 ext2fs COMPAT flags, time_t cleanups, added libext2 version
181 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
183 6. Made --prefix option work in configure. All the install path
184 are now based on the configure parameters.
186 7. Added the Quick File Access mode in dump/restore, contributed
187 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
188 a file tape position for each inode, and this file is used by
189 restore (if called with parameter Q and the filename)
190 to directly position the tape at the file restore is currently
191 working on. This saves hours when restoring single files from
192 large backups, saves the tapes and the drive's head. Use
193 --enable-qfa option of configure to compile in the QFA support.
195 8. Added the possibility to dump several files and directories
196 in a single invocation of dump. Thanks to Uwe Gohlke
197 <uwe@ugsoft.de> for implementing this option.
199 9. Fixed the dumping and restoring of files with holes
200 (files ending with holes didn't get dumped or restored
203 10. Fixed a socket descriptor leak in dump, which leaved opened
204 3 file descriptors per dump process (and there is one dump
207 11. Fixed dump large file system support, by explicit use of
208 open64/lseek64/etc functions (explicit use needed because
209 e2fsprogs libraries don't behave well when compiled with
210 FILE_OFFSET_BITS=64).
212 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
213 ======================================================================
215 1. Fixed some bugs in the dump -w|-W logic introduced by
216 the previous version. Thanks to Andreas Dilger
217 <adilger@turbolinux.com> for his help on this one.
219 2. Fixed again a compilation problem when using old e2fs
220 headers (filesystem label related). Thanks to many users
221 who reported this stupid error.
223 3. Fixed a build problem on old lib5 based systems dealing with
224 _PATH_MNTTAB being undefined. Thanks to John Adams
225 <johna@onevista.com> for reporting the bug.
227 4. Improved the error detection in restore when creating
228 the temporary files in TMPDIR. Now restore will corectly
229 report a 'no space left on device' error instead of
230 strange errors which could imply an archive corruption.
231 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
232 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
234 5. Added the throughput information in dump's progression
235 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
238 6. Use libext2fs's inode scanning routines, which are particularly
239 robust when dealing with errors (especially when having some
240 bad blocks on the filesystem). Many thanks to Colin
241 <colin@horizon.com> for reporting the bug, investigating
242 the issues, finding a workaround, writing the patch and
243 fully testing it... (of course, if this patch will break
244 anything, he is to blame for :-)).
246 7. Made dump and restore LFS aware. Dump can dump a filesystem
247 containing large files, generate a large file on output and
248 restore can restore them. This feature is not enabled by
249 default, use --enable-largefile option of configure to enable
250 it (you need to have a LFS aware glibc though). Thanks to
251 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
252 and to Theodore T'so <tytso@valinux.com> for his always
255 8. Made dump ask upon a tape write error if it should rewrite
256 the current volume (assume this is a bad tape) or if it should
257 assume an end-of-tape condition (useful for tape drives which
258 behaves badly at the end of the tape). Thanks to Andreas
259 Dilger <adilger@turbolinux.com> for the suggestion.
261 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
262 =======================================================================
264 1. Fixed a small compilation problem due to a change
265 in the definintion of the struct sigaction in
266 glibc 2.0 / libc5. Thanks to Gunther Schlegel
267 <schlegel@riege.de> for reporting the bug and to
268 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
271 2. Modified the label and uuid analysis in order to be
272 self-contained (independant of kernel/libc headers). This
273 should fix the compile with older kernel/libc headers and
274 will preserve the functionality. Thanks to Bernhard Erdmann
275 <bernhard.erdmann@gmx.de> for reporting the bug.
277 3. The 'exclude inode' option, if applied to a directory
278 inode, excludes now correctly all the leaves of this
279 directory. Thanks to John R. Dennison
280 <gerdesas@users.sourceforge.net> for reporting the bug.
282 4. Fixed the '-e' option to disable the possibility
283 to exclude the root inode (which causes the dumps to
284 be unreadable by restore). Prevented array overflow
285 when multiple -e options are used.
287 5. Fixed dump to correctly interpret a filesystem argument
288 which is a mountpoint and it is not an absolute path
289 (as specified in the fstab). Thanks to Bernhard R. Erdmann
290 <be@berdmann.de> for reporting the bug.
292 6. Made dump able to backup files larger than 2 GB. Note that
293 dump still doesn't cope with files larger than 4 GB.
295 7. Restore the real uid and gid before invoking an external
296 RSH program (big hole when dump or restore is suid root!).
298 8. Get the values for the default tape device and the location
299 of fstab file from the system headers. Thanks to
300 Andreas Dilger <adilger@turbolinux.com> for the patch.
302 9. Made dump -w|-W report all recognized filesystems
303 present in either /etc/fstab or /etc/dumpdates, and present
304 the list in the same order as in fstab file. Thanks
305 to Andreas Dilger <adilger@turbolinux.com> for the patch.
307 10. Made dump's -a (automatic end of tape detection) the
308 default. Specifying one of -B, -c, -d or -s options will
309 override the EOM detection. Thanks to Andreas Dilger
310 <adilger@turbolinux.com> for the patch.
312 11. Save the ext2 filesystem label into the dump volume label.
313 Specifying a volume label on the command line (-L option)
314 will override this feature. Thanks to Andreas Dilger
315 <adilger@turbolinux.com> for the patch.
317 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
318 =====================================================================
320 1. Fixed the signal handling in dump (which I broke in 0.4b17)
321 which was causing several strange dump failures (dump
322 hanged or segmentation faults etc).
324 2. Specified the default blocksize in the dump man page.
326 3. Changed two info messages of restore to be written on stdout
327 instead of stderr in order to leave stderr only for errors
328 or warnings. Thanks to Stephen Atwell
329 <satwell@urbana.css.mot.com> for the suggestion.
331 4. Corrected an off by one calculation which prevented
332 dumping a directory having a 1 character name length.
333 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
334 for reporting the bug.
336 5. Reinforce dump in order to allow only level 0 and no
337 -u option when dumping a subdirectory, and document
338 this in the man page. Thanks to Bernhard Erdmann
339 <bernhard.erdmann@gmx.de> for reporting the bug.
341 6. Fixed a small harmless bug in restore which caused
342 in some conditions hard links to be restored several
343 times (therefore generation some warning messages).
344 Thanks to Kenneth Porter <shiva@well.com> for
347 7. Updated the RPM spec file to the latest RedHat version,
348 providing FHS packaging and other cosmetic changes.
349 You will need RPM version >= 3.0.5 in order to build the RPM.
351 8. Updated the configure script to check for libtermcap
352 before checking for libreadline, because we need this
353 library in order to compile the readline support.
355 9. Made dump understand the LABEL= and UUID= notation
356 both in /etc/fstab and on the command line. Note that
357 you will need the /proc filesystem in order to use
358 these notations. Thanks to Erik Troan <ewt@redhat.com>
359 for providing the patch.
361 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
362 ===================================================================
364 1. Fixed a potential buffer overflow in restore. Thanks
365 to Stan Bubrouski <satan@fastdial.net> for reporting
368 2. Fixed a readline-related bug which prevented
369 'cat DUMPFILE | restore -i -f -' from working. Thanks
370 to Charles Karney <karney@users.sourceforge.net>
373 3. Changed a few "panic" into "exit", causing restore to
374 be more stable against some attacks (like the last one
375 reported on Bugtraq, although the last version of restore
376 was not vulnerable - just dumped core). Thanks to
377 Andreas Hasenack <andreas@conectiva.com.br> for reporting
380 4. Removed the suid-root bit on dump and restore in the
381 default build (and generated RPMs). It should be safer
382 now. Users who need the suid-root capabilities in order
383 to make network backups should read first the man page
384 of dump and enable the suid bit manually.
386 5. Added -ltermcap to the compile parameters for restore
387 when using readline support, in order to make the compile
388 process work on some systems (SuSE ?). Thanks to
389 Patrik Schindler <poc@pocnet.net> for reporting the bug.
391 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
392 ====================================================================
394 1. The -F script is called now *only* at the end of a tape,
395 not at the end of the dump. Thanks to Christian Haul
396 <haul@informatik.tu-darmstadt.de> for the bug report.
398 Normally, the device name and the current volume number
399 are passed on the command line of the script. However,
400 if you want the old style script (with no arguments
401 passed on the command line), you can enable it in
402 configure with the --enable-oldstylefscript.
404 2. Use posix signal handling to preserve dump functionality
405 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
408 3. Made the exit code of restore in case of a 'C'ompare
409 command reflect the result of the compare. An exit status
410 of 0 means the dump archive is correct, 1 means tape errors,
411 2 means that some files were modified. Thanks to Kenneth Porter
412 <shiva@well.com> for the suggestion.
414 4. Made (finally) quotes work in interactive restore.
416 5. Small fixes in order to allow dump to compile with a
417 really old e2fsprogs version. Thanks to Ian Zimmerman
418 <itz@speakeasy.org> for the bug report.
420 6. Add GNU readline capabilities to interactive restore.
421 Use configure's --enable-readline flag to enable this feature.
422 Thanks to Patrik Schindler <poc@pocnet.net> for the
425 7. Do the compare on the fly in restore 'C' mode (this will
426 allow not to exhaust the available /tmp space when
427 ccmparing large files). Thanks to Kenneth Porter
428 <shiva@well.com> for the suggestion.
430 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
431 ====================================================================
433 1. Fixed some several duplicate 'DUMP: DUMP:' in the
436 2. Corrected the estimation of blocks to dump. Note that
437 this is still wrong for large directory inodes, due
438 to the size of a BSD directory entry on the tape
439 (estimation is based on the size of the ext2 directory,
440 which is smaller because it doesn't contain the null
441 character at the end).
443 3. Made dump report the total number of MB written to
444 tape at the end of run. Thanks to W. Reilly Cooley
445 <wcooley@nakedape.cc> for the patch.
447 4. Added the -X option to restore giving the possibility
448 to read the names of the files to be extracted/listed
449 from a text file (in addition of the command line).
450 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
453 5. Added the device name and the current volume number
454 as arguments to the end of tape script (dump -F option).
456 6. Made the multi-volume dump work again (after having
457 broken it in 0.4b15).
459 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
460 ===================================================================
462 1. Added a prompt command in interactive restore mode. Thanks
463 to Andreas Dilger <adilger@home.com> for the patch.
465 2. Fixed a buffer overflow problem in dump (caused by
466 not checking the size of the filesystem parameter).
467 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
468 reporting this on Bugtraq (and to several dump users
469 who forwarded me his mail).
471 3. Added the '-F script' option to dump in order to
472 launch a script at the end of each tape (to be used
473 with a tape changer, or to notify the sysadmin by
476 4. Fixed a bug in restore compare code caused by the changes
479 5. Fixed the treatment of options using the old BSD syntax
480 in both dump and restore.
482 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
483 =======================================================================
485 1. Fixed a bug in dump which may have caused invalid deleted
486 directories to be dumped out if they were deleted after the
487 mapping pass. This could occure on active filesystem and lead
488 to heap corruption (causing dump malfunction in many possible ways).
489 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
490 bug and submitting the patch.
492 2. Fixed the handling of the filesystem parameter in dump. A
493 '/mnt/disk' parameter caused the disk contents to be dumped,
494 but a '/mnt/disk/' parameter caused the mountpoint directory
495 to be dumped (generally an empty directory).
497 3. Improved the output of dump in order to tell which directory
498 it is currently dumping (when dumping a subtree).
500 4. Added the '-e' exclude inode option to dump. Thanks to
501 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
503 5. Added a REPORTING-BUGS file in order to provide a guide
504 on how to correctly report a bug in dump/restore.
506 6. Fixed a restore problem when restoring a hard link to an inode
507 having the immutable or append-only attribute set. Thanks to
508 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
510 7. Fixed a compatibility problem between dumps made on little
511 endian machines (the format was correct) and big endian
512 machines (the format was incorrect). This fix break the
513 compatibility with the older dumps made on big endian
514 machines (sparc, m86k, ppc etc). For the first time in
515 linux dump's history (I believe), the dumps made by *BSD,
516 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
517 so interchangeable. Thanks to Rob Cermak
518 <cermak@ahab.rutgers.edu> for submitting the bug and
519 helping me test the fix.
521 8. Fixed the way dump reports the remaining percent/time, if
522 the number of blocks actually dumped exceeds the estimated
523 number of blocks. Thanks to Jean-Paul van der Jagt
524 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
526 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
527 ======================================================================
529 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
530 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
532 2. Removed the requirement to build the RPM as root from the
533 spec file. Thanks to Christian Weisgerber
534 <naddy@mips.rhein-neckar.de> for submitting this.
536 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
537 causing dump to block when dumping really huge filesystems.
538 Many thanks to Patrik Schindler <poc@pocnet.net> for
539 helping me find this bug.
541 4. Fixed the treatment for an interrupt signal when dump access
542 the remote tape through RSH. Thanks to Christian Weisgerber
543 <naddy@mips.rhein-neckar.de> for providing the patch.
545 5. Fixed a bug which was causing dump/restore to display
546 garbage characters instead of the remote host name.
548 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
549 =====================================================================
551 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
552 <kukuk@suse.de> for submitting the patch.
554 2. Fix for the exit code when using the size estimate option of
555 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
556 submitting the patch.
558 3. Handle EINTR in atomical reads/writes in dump, which was causing
559 dump to fail on some systems. Thanks to Eric Jergensen
560 <eric@dvns.com> for reporting the bug and submitting the patch.
562 4. Handle more than 16 characters for the device names in dumpdates.
563 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
564 tracking down the problem and proposing the solution.
566 5. Fixed a bug in dump which prevented the creation of the
567 dumpdates file when doing a 0-level dump without already
568 having a dumpdates file. Thanks to Patrik Schindler
569 <poc@pocnet.net> for reporting the bug.
571 6. Changed the way dump 'S' flag reports the size estimate
572 from number of blocks into bytes (making it compatible
573 with the Solaris version, and simplifying things for
574 amanda users). Thanks to Jason L Tibbitts III
575 <tibbs@math.uh.edu> for reporting the bug.
577 7. Fixed a compatibility problem in linux/alpha dump tape format.
578 Now the linux/alpha dump are (again) compatible with the
579 other dump formats. But this breaks compatibility with
580 older dumps made on alpha. Thanks to Mike Tibor
581 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
583 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
584 ======================================================================
586 1. Added a '--enable-kerberos' to configure.
588 2. Added a 'S' option to dump which determines the amount of space
589 that is needed to perform the dump without actually doing it, similar
590 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
591 <cermak@ahab.rutgers.edu>.
593 3. Added a 'M' multi-volume option to dump and restore which enables
594 dumping to multiple files (useful when dumping to an ext2
595 partition to make several dump files in order to bypass the 2GB
596 file size limitation). The 'f' argument is treated as a prefix and
597 the output files will be named <prefix>001, <prefix>002 etc. With
598 the 'M' flag, restore automatically selects the right file without
599 asking to enter a new tape each time.
601 4. Fixed a memory leak which was causing dump to grow very big
602 (270MB when dumping a 10GB filesystem...). Thanks to Jason
603 Fearon <jasonf@netrider.org.au> for reporting the bug.
605 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
606 ======================================================================
608 1. Make configure test if the system glob routines support
609 extended syntax (ALTDIRFUNC). If not, use the internal glob
610 routines instead of system ones. Thanks to Bernhard Sadlowski
611 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
612 and helping me resolve this and other minor libc5 compiling
615 2. Fix a problem when dumping a ext2fs with the 'filetype'
616 feature enabled. Thanks to Patrick J. LoPresti
617 <patl@cag.lcs.mit.edu> for reporting the bug and to
618 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
620 3. Made the nodump flag work on directories. A directory which
621 has the nodump flag gets never dumped, regardless of its
624 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
625 which allows dump on an active ext3 filesystem. However, this
626 is a "quick and dirty" patch which enables backup of an ext3
627 filesystem through the ext2 compatibility (by ignoring the
628 NEEDS_RECOVERY bit). The journal file is not recognized and
629 it is dumped (it should not).
631 5. Test the superblock compatibility flags when dumping, in order
632 to be sure that we know how to deal with specific features.
634 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
635 ====================================================================
637 1. Use lchown instead of chown, fixing a possible security problem
638 when restoring symlinks (a malicious user could use this
639 to deliberately corrupt the ownership of important system files).
640 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
641 this and providing the patch.
643 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
644 ====================================================================
646 1. Put dump sources under CVS, added Id tags in all files so
647 one can use 'ident' on binary files.
649 2. Added the dump/restore version in the usage text so one can
650 easily verify the version he is using.
652 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
653 a va_start/va_end problem on linux-ppc (always call va_start
654 va_end in pairs each time we use a vararg function).
656 4. Added again the DT_* constants because old libc does not
657 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
658 for submitting the bug report.
660 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
661 this should enable dumping big (huge) filesystems.
663 6. Added the RSH environment variable in order to be able to
664 use a rsh replacement like ssh when doing remote backups (and
665 bypass the security limitations of rcmd). Now you can do remote
666 backups without being root (or making dump setuid root).
668 7. Modified again the way dumpdates works. For incremental dumps,
669 we need to read dumpdates even if we are not using 'u' option.
670 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
673 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
674 ===================================================================
676 1. Removed the 'k' flag from the restore 'about' text if kerberos
679 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
680 to them (fsetflags takes a char*, setflags an open fd!).
682 3. (f)setflags is called only if the flags aren't empty. If the
683 file is a special file, a warning is printed, because changing
684 flags implies opening the device. Normally, a special file
685 should not have any flag... (Debian bug #29775, patch provided
686 by Abhijit Dasgupta <abhijit@ans.net>).
688 4. Made possible to dump a file system not mentioned in /etc/fstab.
689 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
691 5. Changed the default behaviour to not create dumpdates
692 unless 'u' option is specified. Removed the old "debian-patch"
693 which provided the same thing. (Debian bug #38136, #33818).
695 6. Removed all those dump*announce, since they were getting old...
697 7. Added warning messages if dumpdates does not exist and
698 when an inferior level dump does not exist (except for a level 0
701 8. Debugged the glob calls in interactive mode: restore used a
702 dirent struct which was different from the /usr/include/dirent.h
703 one (this used to work, is it a glibc2 change?), so none of the
704 compat glob (which used /usr/include/dirent.h) or the system glob
705 worked. Restore use now the system dirent (and the system
706 DT_* constants), which are compatible with BSD ones.
708 9. Added a configure flag (--with-dumpdatespath) to specify
709 the location of dumpdates file. By default, it is
712 10. Added the "AUTHOR" and "AVAILABILITY" sections and
713 included the current date/version in man pages.
715 11. Corrected the estimation of remaining time when
716 the operator doesn't change the tapes quickly enough. This
717 was an old bug, I thought I corrected it, and discovered
718 that in fact it was corrected in two different places, so
719 the results canceled each other...
721 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
722 ===================================================================
724 1. Integrated multiple patches from RedHat, Debian and SuSE:
726 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
728 - several fixes in the man pages.
729 - update the default tape device to /dev/st0.
730 - many updates for Linux Alpha (byte ordering, size_t etc).
732 - use environment variable for TMPDIR (instead of /tmp).
733 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
734 - workaround egcs bug (RedHat bugs #4281 and #2989).
735 - wire $(OPT) throughout Makefile's.
737 2. Upgrade the dump revision to 1, making possible to dump filesystems
738 made with e2fsprogs-1.15 or newer. Nothing seems to break...
740 3. Fix some compile warnings, prototype all functions.
742 4. Use glibc err/glob instead of internal compatibility
743 routines (only if available).
745 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
746 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
748 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
749 ======================================================================
751 1. Integrated the changes from FreeBSD-3.1-RELEASE
752 (mostly bug fixes, buffer overruns, dump has now an "automatic
753 tape length calculation" flag, dump/restore can use kerberos now
754 (this is NOT tested), use environment variables for TAPE and
757 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
759 3. Corrected a bug in restore when using 'C' option with multi-volumes
760 tapes (files splited accros two tapes give "size changed" errors
763 4. Corrected the long standing bug when dumping multiple tapes.
764 This works for me, needs further testing.
766 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
767 ====================================================================
769 1. Dump now runs correctly on kernels 2.1.x
770 Fix made by Gerald Peters <gapeters@worldnet.att.net>
772 Changes between versions 0.4b2 and 0.4b3
773 ========================================
775 1. Use realpath() if available
779 Changes between versions 0.4b1 and 0.4b2
780 ========================================
782 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
785 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
787 3. Fixed configure.in to correctly handle --enable-rmt
789 Changes between versions 0.3 and 0.4b1
790 ======================================
792 1. Integrated the changes from 4.4BSD-Lite2
794 2. Integrated the patches from Debian and Red Hat
796 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
798 4. Changed dump to use the Ext2fs library to get block addresses. This
799 should solve the endianness problem on SparcLinux.
801 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
802 distribution's one) to use autoconf
804 6. Fixed a few minor bugs
806 Changes between versions 0.2e and 0.2f
807 ======================================
809 1. Added the creation of named pipes (fifos) in restore.
811 2. Added the -N flag in the restore manual page.
813 3. Added the file kernel.patch which contains the llseek() optimization
814 patch for 1.2.x kernels.
816 4. Fixed a bug in the restoration of symbolic links: owner and group were
819 5. Integrated some changes from FreeBSD 2.2.
821 6. Added a call to ftruncate() after restoring each file to restore
822 correctly files ending by a hole.
824 Changes between versions 0.2d and 0.2e
825 ======================================
827 1. Fixed a bug in the "set owner/mode" process. Every file was restored
828 with owner = root (0) and group = root/wheel/whatever (0).
830 Changes between versions 0.2c and 0.2d
831 ======================================
833 1. Dump is now able to backup 2GB+ filesystems.
835 2. Dump and restore can now be linked as static binaries.
837 Changes between versions 0.2b and 0.2c
838 ======================================
840 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
842 Changes between versions 0.2a and 0.2b
843 ======================================
845 1. Really fixed the bug that I should have corrected in 0.2a.
847 2. Enabled optimization again.
849 Changes between versions 0.2 and 0.2a
850 =====================================
852 1. Disabled the optimization during compilation.
854 Changes between versions 0.1 and 0.2
855 ====================================
857 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
858 the fs_type field (actually, I modified the file fstab.c to make it
859 use the mntent functions).
861 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
862 made by dump should be readable by the BSD restore and backups made
863 by the BSD dump should be readable by restore. Unfortunately, this
864 means that the dump format has changed between version 0.1 and version
867 3. Dump is now able to backup a subtree, it is no longer limited to whole
868 filesystems like the BSD version.
870 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
873 Changes between versions 0.0 and 0.1
874 ====================================
876 1. Now create links rdump and rrestore during the `make install' step.
878 2. Linux port specific bugs added to the manual pages
880 3. Incorrect estimation of the number of tapes blocks fixed when doing
883 4. Better ls-like format in restore in interactive mode.
