3 Changes between versions 0.4b21 and 0.4b22 (released ????????????????)
4 ======================================================================
6 1. Made dump report the number of blocks dumped per volume.
7 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
9 2. Fix a bug in dump where waiting too much at the 'change volumes'
10 question caused the volume to be rewritten. Thanks to
11 Graham Reed <greed@users.sourceforge.net> for reporting the
12 bug and providing a patch.
14 3. Added a compression option to dump, contributed by Jerry
15 Peters <gapeters@worldnet.att.net>.
17 WARNING: the compression works only on files/pipes and
18 drives supporting variable block size.
20 WARNING2: tapes created using the compression feature are
21 incompatible with the standard dump tape format, and a
22 version of restore >= 0.4b22 will be needed for extraction.
24 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
25 architectures. Thanks to Paul Slootman <paul@debian.org> for
26 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
29 5. Many cleanups (CPP defines, const char warnings, check of
30 ext2fs COMPAT flags, time_t cleanups, added libext2 version
31 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
33 6. Made --prefix option work in configure. All the install path
34 are now based on the configure parameters.
36 7. Added the Quick File Access mode in dump/restore, contributed
37 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
38 a file tape position for each inode, and this file is used by
39 restore (if called with parameter Q and the filename)
40 to directly position the tape at the file restore is currently
41 working on. This saves hours when restoring single files from
42 large backups, saves the tapes and the drive's head. Use
43 --enable-qfa option of configure to compile in the QFA support.
45 8. Added the possibility to dump several files and directories
46 in a single invocation of dump. Thanks to Uwe Gohlke
47 <uwe@ugsoft.de> for implementing this option.
49 9. Fixed the dumping and restoring of files with holes
50 (files ending with holes didn't get dumped or restored
53 10. Fixed a socket descriptor leak in dump, which leaved opened
54 3 file descriptors per dump process (and there is one dump
57 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
58 ======================================================================
60 1. Fixed some bugs in the dump -w|-W logic introduced by
61 the previous version. Thanks to Andreas Dilger
62 <adilger@turbolinux.com> for his help on this one.
64 2. Fixed again a compilation problem when using old e2fs
65 headers (filesystem label related). Thanks to many users
66 who reported this stupid error.
68 3. Fixed a build problem on old lib5 based systems dealing with
69 _PATH_MNTTAB being undefined. Thanks to John Adams
70 <johna@onevista.com> for reporting the bug.
72 4. Improved the error detection in restore when creating
73 the temporary files in TMPDIR. Now restore will corectly
74 report a 'no space left on device' error instead of
75 strange errors which could imply an archive corruption.
76 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
77 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
79 5. Added the throughput information in dump's progression
80 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
83 6. Use libext2fs's inode scanning routines, which are particularly
84 robust when dealing with errors (especially when having some
85 bad blocks on the filesystem). Many thanks to Colin
86 <colin@horizon.com> for reporting the bug, investigating
87 the issues, finding a workaround, writing the patch and
88 fully testing it... (of course, if this patch will break
89 anything, he is to blame for :-)).
91 7. Made dump and restore LFS aware. Dump can dump a filesystem
92 containing large files, generate a large file on output and
93 restore can restore them. This feature is not enabled by
94 default, use --enable-largefile option of configure to enable
95 it (you need to have a LFS aware glibc though). Thanks to
96 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
97 and to Theodore T'so <tytso@valinux.com> for his always
100 8. Made dump ask upon a tape write error if it should rewrite
101 the current volume (assume this is a bad tape) or if it should
102 assume an end-of-tape condition (useful for tape drives which
103 behaves badly at the end of the tape). Thanks to Andreas
104 Dilger <adilger@turbolinux.com> for the suggestion.
106 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
107 =======================================================================
109 1. Fixed a small compilation problem due to a change
110 in the definintion of the struct sigaction in
111 glibc 2.0 / libc5. Thanks to Gunther Schlegel
112 <schlegel@riege.de> for reporting the bug and to
113 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
116 2. Modified the label and uuid analysis in order to be
117 self-contained (independant of kernel/libc headers). This
118 should fix the compile with older kernel/libc headers and
119 will preserve the functionality. Thanks to Bernhard Erdmann
120 <bernhard.erdmann@gmx.de> for reporting the bug.
122 3. The 'exclude inode' option, if applied to a directory
123 inode, excludes now correctly all the leaves of this
124 directory. Thanks to John R. Dennison
125 <gerdesas@users.sourceforge.net> for reporting the bug.
127 4. Fixed the '-e' option to disable the possibility
128 to exclude the root inode (which causes the dumps to
129 be unreadable by restore). Prevented array overflow
130 when multiple -e options are used.
132 5. Fixed dump to correctly interpret a filesystem argument
133 which is a mountpoint and it is not an absolute path
134 (as specified in the fstab). Thanks to Bernhard R. Erdmann
135 <be@berdmann.de> for reporting the bug.
137 6. Made dump able to backup files larger than 2 GB. Note that
138 dump still doesn't cope with files larger than 4 GB.
140 7. Restore the real uid and gid before invoking an external
141 RSH program (big hole when dump or restore is suid root!).
143 8. Get the values for the default tape device and the location
144 of fstab file from the system headers. Thanks to
145 Andreas Dilger <adilger@turbolinux.com> for the patch.
147 9. Made dump -w|-W report all recognized filesystems
148 present in either /etc/fstab or /etc/dumpdates, and present
149 the list in the same order as in fstab file. Thanks
150 to Andreas Dilger <adilger@turbolinux.com> for the patch.
152 10. Made dump's -a (automatic end of tape detection) the
153 default. Specifying one of -B, -c, -d or -s options will
154 override the EOM detection. Thanks to Andreas Dilger
155 <adilger@turbolinux.com> for the patch.
157 11. Save the ext2 filesystem label into the dump volume label.
158 Specifying a volume label on the command line (-L option)
159 will override this feature. Thanks to Andreas Dilger
160 <adilger@turbolinux.com> for the patch.
162 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
163 =====================================================================
165 1. Fixed the signal handling in dump (which I broke in 0.4b17)
166 which was causing several strange dump failures (dump
167 hanged or segmentation faults etc).
169 2. Specified the default blocksize in the dump man page.
171 3. Changed two info messages of restore to be written on stdout
172 instead of stderr in order to leave stderr only for errors
173 or warnings. Thanks to Stephen Atwell
174 <satwell@urbana.css.mot.com> for the suggestion.
176 4. Corrected an off by one calculation which prevented
177 dumping a directory having a 1 character name length.
178 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
179 for reporting the bug.
181 5. Reinforce dump in order to allow only level 0 and no
182 -u option when dumping a subdirectory, and document
183 this in the man page. Thanks to Bernhard Erdmann
184 <bernhard.erdmann@gmx.de> for reporting the bug.
186 6. Fixed a small harmless bug in restore which caused
187 in some conditions hard links to be restored several
188 times (therefore generation some warning messages).
189 Thanks to Kenneth Porter <shiva@well.com> for
192 7. Updated the RPM spec file to the latest RedHat version,
193 providing FHS packaging and other cosmetic changes.
194 You will need RPM version >= 3.0.5 in order to build the RPM.
196 8. Updated the configure script to check for libtermcap
197 before checking for libreadline, because we need this
198 library in order to compile the readline support.
200 9. Made dump understand the LABEL= and UUID= notation
201 both in /etc/fstab and on the command line. Note that
202 you will need the /proc filesystem in order to use
203 these notations. Thanks to Erik Troan <ewt@redhat.com>
204 for providing the patch.
206 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
207 ===================================================================
209 1. Fixed a potential buffer overflow in restore. Thanks
210 to Stan Bubrouski <satan@fastdial.net> for reporting
213 2. Fixed a readline-related bug which prevented
214 'cat DUMPFILE | restore -i -f -' from working. Thanks
215 to Charles Karney <karney@users.sourceforge.net>
218 3. Changed a few "panic" into "exit", causing restore to
219 be more stable against some attacks (like the last one
220 reported on Bugtraq, although the last version of restore
221 was not vulnerable - just dumped core). Thanks to
222 Andreas Hasenack <andreas@conectiva.com.br> for reporting
225 4. Removed the suid-root bit on dump and restore in the
226 default build (and generated RPMs). It should be safer
227 now. Users who need the suid-root capabilities in order
228 to make network backups should read first the man page
229 of dump and enable the suid bit manually.
231 5. Added -ltermcap to the compile parameters for restore
232 when using readline support, in order to make the compile
233 process work on some systems (SuSE ?). Thanks to
234 Patrik Schindler <poc@pocnet.net> for reporting the bug.
236 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
237 ====================================================================
239 1. The -F script is called now *only* at the end of a tape,
240 not at the end of the dump. Thanks to Christian Haul
241 <haul@informatik.tu-darmstadt.de> for the bug report.
243 Normally, the device name and the current volume number
244 are passed on the command line of the script. However,
245 if you want the old style script (with no arguments
246 passed on the command line), you can enable it in
247 configure with the --enable-oldstylefscript.
249 2. Use posix signal handling to preserve dump functionality
250 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
253 3. Made the exit code of restore in case of a 'C'ompare
254 command reflect the result of the compare. An exit status
255 of 0 means the dump archive is correct, 1 means tape errors,
256 2 means that some files were modified. Thanks to Kenneth Porter
257 <shiva@well.com> for the suggestion.
259 4. Made (finally) quotes work in interactive restore.
261 5. Small fixes in order to allow dump to compile with a
262 really old e2fsprogs version. Thanks to Ian Zimmerman
263 <itz@speakeasy.org> for the bug report.
265 6. Add GNU readline capabilities to interactive restore.
266 Use configure's --enable-readline flag to enable this feature.
267 Thanks to Patrik Schindler <poc@pocnet.net> for the
270 7. Do the compare on the fly in restore 'C' mode (this will
271 allow not to exhaust the available /tmp space when
272 ccmparing large files). Thanks to Kenneth Porter
273 <shiva@well.com> for the suggestion.
275 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
276 ====================================================================
278 1. Fixed some several duplicate 'DUMP: DUMP:' in the
281 2. Corrected the estimation of blocks to dump. Note that
282 this is still wrong for large directory inodes, due
283 to the size of a BSD directory entry on the tape
284 (estimation is based on the size of the ext2 directory,
285 which is smaller because it doesn't contain the null
286 character at the end).
288 3. Made dump report the total number of MB written to
289 tape at the end of run. Thanks to W. Reilly Cooley
290 <wcooley@nakedape.cc> for the patch.
292 4. Added the -X option to restore giving the possibility
293 to read the names of the files to be extracted/listed
294 from a text file (in addition of the command line).
295 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
298 5. Added the device name and the current volume number
299 as arguments to the end of tape script (dump -F option).
301 6. Made the multi-volume dump work again (after having
302 broken it in 0.4b15).
304 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
305 ===================================================================
307 1. Added a prompt command in interactive restore mode. Thanks
308 to Andreas Dilger <adilger@home.com> for the patch.
310 2. Fixed a buffer overflow problem in dump (caused by
311 not checking the size of the filesystem parameter).
312 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
313 reporting this on Bugtraq (and to several dump users
314 who forwarded me his mail).
316 3. Added the '-F script' option to dump in order to
317 launch a script at the end of each tape (to be used
318 with a tape changer, or to notify the sysadmin by
321 4. Fixed a bug in restore compare code caused by the changes
324 5. Fixed the treatment of options using the old BSD syntax
325 in both dump and restore.
327 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
328 =======================================================================
330 1. Fixed a bug in dump which may have caused invalid deleted
331 directories to be dumped out if they were deleted after the
332 mapping pass. This could occure on active filesystem and lead
333 to heap corruption (causing dump malfunction in many possible ways).
334 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
335 bug and submitting the patch.
337 2. Fixed the handling of the filesystem parameter in dump. A
338 '/mnt/disk' parameter caused the disk contents to be dumped,
339 but a '/mnt/disk/' parameter caused the mountpoint directory
340 to be dumped (generally an empty directory).
342 3. Improved the output of dump in order to tell which directory
343 it is currently dumping (when dumping a subtree).
345 4. Added the '-e' exclude inode option to dump. Thanks to
346 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
348 5. Added a REPORTING-BUGS file in order to provide a guide
349 on how to correctly report a bug in dump/restore.
351 6. Fixed a restore problem when restoring a hard link to an inode
352 having the immutable or append-only attribute set. Thanks to
353 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
355 7. Fixed a compatibility problem between dumps made on little
356 endian machines (the format was correct) and big endian
357 machines (the format was incorrect). This fix break the
358 compatibility with the older dumps made on big endian
359 machines (sparc, m86k, ppc etc). For the first time in
360 linux dump's history (I believe), the dumps made by *BSD,
361 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
362 so interchangeable. Thanks to Rob Cermak
363 <cermak@ahab.rutgers.edu> for submitting the bug and
364 helping me test the fix.
366 8. Fixed the way dump reports the remaining percent/time, if
367 the number of blocks actually dumped exceeds the estimated
368 number of blocks. Thanks to Jean-Paul van der Jagt
369 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
371 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
372 ======================================================================
374 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
375 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
377 2. Removed the requirement to build the RPM as root from the
378 spec file. Thanks to Christian Weisgerber
379 <naddy@mips.rhein-neckar.de> for submitting this.
381 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
382 causing dump to block when dumping really huge filesystems.
383 Many thanks to Patrik Schindler <poc@pocnet.net> for
384 helping me find this bug.
386 4. Fixed the treatment for an interrupt signal when dump access
387 the remote tape through RSH. Thanks to Christian Weisgerber
388 <naddy@mips.rhein-neckar.de> for providing the patch.
390 5. Fixed a bug which was causing dump/restore to display
391 garbage characters instead of the remote host name.
393 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
394 =====================================================================
396 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
397 <kukuk@suse.de> for submitting the patch.
399 2. Fix for the exit code when using the size estimate option of
400 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
401 submitting the patch.
403 3. Handle EINTR in atomical reads/writes in dump, which was causing
404 dump to fail on some systems. Thanks to Eric Jergensen
405 <eric@dvns.com> for reporting the bug and submitting the patch.
407 4. Handle more than 16 characters for the device names in dumpdates.
408 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
409 tracking down the problem and proposing the solution.
411 5. Fixed a bug in dump which prevented the creation of the
412 dumpdates file when doing a 0-level dump without already
413 having a dumpdates file. Thanks to Patrik Schindler
414 <poc@pocnet.net> for reporting the bug.
416 6. Changed the way dump 'S' flag reports the size estimate
417 from number of blocks into bytes (making it compatible
418 with the Solaris version, and simplifying things for
419 amanda users). Thanks to Jason L Tibbitts III
420 <tibbs@math.uh.edu> for reporting the bug.
422 7. Fixed a compatibility problem in linux/alpha dump tape format.
423 Now the linux/alpha dump are (again) compatible with the
424 other dump formats. But this breaks compatibility with
425 older dumps made on alpha. Thanks to Mike Tibor
426 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
428 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
429 ======================================================================
431 1. Added a '--enable-kerberos' to configure.
433 2. Added a 'S' option to dump which determines the amount of space
434 that is needed to perform the dump without actually doing it, similar
435 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
436 <cermak@ahab.rutgers.edu>.
438 3. Added a 'M' multi-volume option to dump and restore which enables
439 dumping to multiple files (useful when dumping to an ext2
440 partition to make several dump files in order to bypass the 2GB
441 file size limitation). The 'f' argument is treated as a prefix and
442 the output files will be named <prefix>001, <prefix>002 etc. With
443 the 'M' flag, restore automatically selects the right file without
444 asking to enter a new tape each time.
446 4. Fixed a memory leak which was causing dump to grow very big
447 (270MB when dumping a 10GB filesystem...). Thanks to Jason
448 Fearon <jasonf@netrider.org.au> for reporting the bug.
450 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
451 ======================================================================
453 1. Make configure test if the system glob routines support
454 extended syntax (ALTDIRFUNC). If not, use the internal glob
455 routines instead of system ones. Thanks to Bernhard Sadlowski
456 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
457 and helping me resolve this and other minor libc5 compiling
460 2. Fix a problem when dumping a ext2fs with the 'filetype'
461 feature enabled. Thanks to Patrick J. LoPresti
462 <patl@cag.lcs.mit.edu> for reporting the bug and to
463 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
465 3. Made the nodump flag work on directories. A directory which
466 has the nodump flag gets never dumped, regardless of its
469 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
470 which allows dump on an active ext3 filesystem. However, this
471 is a "quick and dirty" patch which enables backup of an ext3
472 filesystem through the ext2 compatibility (by ignoring the
473 NEEDS_RECOVERY bit). The journal file is not recognized and
474 it is dumped (it should not).
476 5. Test the superblock compatibility flags when dumping, in order
477 to be sure that we know how to deal with specific features.
479 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
480 ====================================================================
482 1. Use lchown instead of chown, fixing a possible security problem
483 when restoring symlinks (a malicious user could use this
484 to deliberately corrupt the ownership of important system files).
485 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
486 this and providing the patch.
488 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
489 ====================================================================
491 1. Put dump sources under CVS, added Id tags in all files so
492 one can use 'ident' on binary files.
494 2. Added the dump/restore version in the usage text so one can
495 easily verify the version he is using.
497 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
498 a va_start/va_end problem on linux-ppc (always call va_start
499 va_end in pairs each time we use a vararg function).
501 4. Added again the DT_* constants because old libc does not
502 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
503 for submitting the bug report.
505 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
506 this should enable dumping big (huge) filesystems.
508 6. Added the RSH environment variable in order to be able to
509 use a rsh replacement like ssh when doing remote backups (and
510 bypass the security limitations of rcmd). Now you can do remote
511 backups without being root (or making dump setuid root).
513 7. Modified again the way dumpdates works. For incremental dumps,
514 we need to read dumpdates even if we are not using 'u' option.
515 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
518 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
519 ===================================================================
521 1. Removed the 'k' flag from the restore 'about' text if kerberos
524 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
525 to them (fsetflags takes a char*, setflags an open fd!).
527 3. (f)setflags is called only if the flags aren't empty. If the
528 file is a special file, a warning is printed, because changing
529 flags implies opening the device. Normally, a special file
530 should not have any flag... (Debian bug #29775, patch provided
531 by Abhijit Dasgupta <abhijit@ans.net>).
533 4. Made possible to dump a file system not mentioned in /etc/fstab.
534 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
536 5. Changed the default behaviour to not create dumpdates
537 unless 'u' option is specified. Removed the old "debian-patch"
538 which provided the same thing. (Debian bug #38136, #33818).
540 6. Removed all those dump*announce, since they were getting old...
542 7. Added warning messages if dumpdates does not exist and
543 when an inferior level dump does not exist (except for a level 0
546 8. Debugged the glob calls in interactive mode: restore used a
547 dirent struct which was different from the /usr/include/dirent.h
548 one (this used to work, is it a glibc2 change?), so none of the
549 compat glob (which used /usr/include/dirent.h) or the system glob
550 worked. Restore use now the system dirent (and the system
551 DT_* constants), which are compatible with BSD ones.
553 9. Added a configure flag (--with-dumpdatespath) to specify
554 the location of dumpdates file. By default, it is
557 10. Added the "AUTHOR" and "AVAILABILITY" sections and
558 included the current date/version in man pages.
560 11. Corrected the estimation of remaining time when
561 the operator doesn't change the tapes quickly enough. This
562 was an old bug, I thought I corrected it, and discovered
563 that in fact it was corrected in two different places, so
564 the results canceled each other...
566 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
567 ===================================================================
569 1. Integrated multiple patches from RedHat, Debian and SuSE:
571 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
573 - several fixes in the man pages.
574 - update the default tape device to /dev/st0.
575 - many updates for Linux Alpha (byte ordering, size_t etc).
577 - use environment variable for TMPDIR (instead of /tmp).
578 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
579 - workaround egcs bug (RedHat bugs #4281 and #2989).
580 - wire $(OPT) throughout Makefile's.
582 2. Upgrade the dump revision to 1, making possible to dump filesystems
583 made with e2fsprogs-1.15 or newer. Nothing seems to break...
585 3. Fix some compile warnings, prototype all functions.
587 4. Use glibc err/glob instead of internal compatibility
588 routines (only if available).
590 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
591 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
593 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
594 ======================================================================
596 1. Integrated the changes from FreeBSD-3.1-RELEASE
597 (mostly bug fixes, buffer overruns, dump has now an "automatic
598 tape length calculation" flag, dump/restore can use kerberos now
599 (this is NOT tested), use environment variables for TAPE and
602 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
604 3. Corrected a bug in restore when using 'C' option with multi-volumes
605 tapes (files splited accros two tapes give "size changed" errors
608 4. Corrected the long standing bug when dumping multiple tapes.
609 This works for me, needs further testing.
611 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
612 ====================================================================
614 1. Dump now runs correctly on kernels 2.1.x
615 Fix made by Gerald Peters <gapeters@worldnet.att.net>
617 Changes between versions 0.4b2 and 0.4b3
618 ========================================
620 1. Use realpath() if available
624 Changes between versions 0.4b1 and 0.4b2
625 ========================================
627 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
630 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
632 3. Fixed configure.in to correctly handle --enable-rmt
634 Changes between versions 0.3 and 0.4b1
635 ======================================
637 1. Integrated the changes from 4.4BSD-Lite2
639 2. Integrated the patches from Debian and Red Hat
641 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
643 4. Changed dump to use the Ext2fs library to get block addresses. This
644 should solve the endianness problem on SparcLinux.
646 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
647 distribution's one) to use autoconf
649 6. Fixed a few minor bugs
651 Changes between versions 0.2e and 0.2f
652 ======================================
654 1. Added the creation of named pipes (fifos) in restore.
656 2. Added the -N flag in the restore manual page.
658 3. Added the file kernel.patch which contains the llseek() optimization
659 patch for 1.2.x kernels.
661 4. Fixed a bug in the restoration of symbolic links: owner and group were
664 5. Integrated some changes from FreeBSD 2.2.
666 6. Added a call to ftruncate() after restoring each file to restore
667 correctly files ending by a hole.
669 Changes between versions 0.2d and 0.2e
670 ======================================
672 1. Fixed a bug in the "set owner/mode" process. Every file was restored
673 with owner = root (0) and group = root/wheel/whatever (0).
675 Changes between versions 0.2c and 0.2d
676 ======================================
678 1. Dump is now able to backup 2GB+ filesystems.
680 2. Dump and restore can now be linked as static binaries.
682 Changes between versions 0.2b and 0.2c
683 ======================================
685 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
687 Changes between versions 0.2a and 0.2b
688 ======================================
690 1. Really fixed the bug that I should have corrected in 0.2a.
692 2. Enabled optimization again.
694 Changes between versions 0.2 and 0.2a
695 =====================================
697 1. Disabled the optimization during compilation.
699 Changes between versions 0.1 and 0.2
700 ====================================
702 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
703 the fs_type field (actually, I modified the file fstab.c to make it
704 use the mntent functions).
706 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
707 made by dump should be readable by the BSD restore and backups made
708 by the BSD dump should be readable by restore. Unfortunately, this
709 means that the dump format has changed between version 0.1 and version
712 3. Dump is now able to backup a subtree, it is no longer limited to whole
713 filesystems like the BSD version.
715 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
718 Changes between versions 0.0 and 0.1
719 ====================================
721 1. Now create links rdump and rrestore during the `make install' step.
723 2. Linux port specific bugs added to the manual pages
725 3. Incorrect estimation of the number of tapes blocks fixed when doing
728 4. Better ls-like format in restore in interactive mode.
