3 Changes between versions 0.4b22 and 0.4b23 (released ????????????)
4 ==================================================================
6 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
7 Marcus Meissner (Caldera International Security Dept.).
9 2. Implement the Sun rmt extended protocol. Patch submitted
10 by Ian Gordon <iangordon@users.sourceforge.net>.
12 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
13 the linux kernel header. This ensures that dump always has the
14 latest version of this file. Patch submitted by
15 Andreas Dilger <adilger@turbolinux.com>.
17 4. Report any filesystem present in either /etc/fstab with a
18 positive passno or /etc/dumpdates in dump -w output.
19 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
21 5. Fixed the looping problem in dump introduced in the
24 6. Changed the -B option of dump to limit the size of
25 _compressed_ output per volume if compression is on.
26 Patch contributed by Helmut Jarausch
27 <jarausch@igpm.rwth-aachen.de>.
29 7. Fixed a bug in reading the operator typed file/tape path for
30 the next volume in restore.
32 8. Implemented a "-F script" option to restore which permits the
33 user to specify a script which will be launched at the
34 beginning of each tape, useful for automatic programming of
35 tape changers for example. See the restore man page for the
36 script parameters and return codes.
38 9. Small fix for the QFA routines provided by Uwe Gohlke
39 <uwe@ugsoft.de>, and some recommendations for QFA uses in
42 10. Fixed the multivolume restoring where making a mistake
43 to the 'Mount next tape' prompt caused several blocks to
46 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
47 ==================================================================
49 1. Made dump report the number of blocks dumped per volume.
50 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
52 2. Fix a bug in dump where waiting too much at the 'change volumes'
53 question caused the volume to be rewritten. Thanks to
54 Graham Reed <greed@users.sourceforge.net> for reporting the
55 bug and providing a patch.
57 3. Added a compression option to dump, contributed by Jerry
58 Peters <gapeters@worldnet.att.net>.
60 WARNING: the compression works only on files/pipes and
61 drives supporting variable block size.
63 WARNING2: tapes created using the compression feature are
64 incompatible with the standard dump tape format, and a
65 version of restore >= 0.4b22 will be needed for extraction.
67 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
68 architectures. Thanks to Paul Slootman <paul@debian.org> for
69 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
72 5. Many cleanups (CPP defines, const char warnings, check of
73 ext2fs COMPAT flags, time_t cleanups, added libext2 version
74 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
76 6. Made --prefix option work in configure. All the install path
77 are now based on the configure parameters.
79 7. Added the Quick File Access mode in dump/restore, contributed
80 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
81 a file tape position for each inode, and this file is used by
82 restore (if called with parameter Q and the filename)
83 to directly position the tape at the file restore is currently
84 working on. This saves hours when restoring single files from
85 large backups, saves the tapes and the drive's head. Use
86 --enable-qfa option of configure to compile in the QFA support.
88 8. Added the possibility to dump several files and directories
89 in a single invocation of dump. Thanks to Uwe Gohlke
90 <uwe@ugsoft.de> for implementing this option.
92 9. Fixed the dumping and restoring of files with holes
93 (files ending with holes didn't get dumped or restored
96 10. Fixed a socket descriptor leak in dump, which leaved opened
97 3 file descriptors per dump process (and there is one dump
100 11. Fixed dump large file system support, by explicit use of
101 open64/lseek64/etc functions (explicit use needed because
102 e2fsprogs libraries don't behave well when compiled with
103 FILE_OFFSET_BITS=64).
105 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
106 ======================================================================
108 1. Fixed some bugs in the dump -w|-W logic introduced by
109 the previous version. Thanks to Andreas Dilger
110 <adilger@turbolinux.com> for his help on this one.
112 2. Fixed again a compilation problem when using old e2fs
113 headers (filesystem label related). Thanks to many users
114 who reported this stupid error.
116 3. Fixed a build problem on old lib5 based systems dealing with
117 _PATH_MNTTAB being undefined. Thanks to John Adams
118 <johna@onevista.com> for reporting the bug.
120 4. Improved the error detection in restore when creating
121 the temporary files in TMPDIR. Now restore will corectly
122 report a 'no space left on device' error instead of
123 strange errors which could imply an archive corruption.
124 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
125 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
127 5. Added the throughput information in dump's progression
128 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
131 6. Use libext2fs's inode scanning routines, which are particularly
132 robust when dealing with errors (especially when having some
133 bad blocks on the filesystem). Many thanks to Colin
134 <colin@horizon.com> for reporting the bug, investigating
135 the issues, finding a workaround, writing the patch and
136 fully testing it... (of course, if this patch will break
137 anything, he is to blame for :-)).
139 7. Made dump and restore LFS aware. Dump can dump a filesystem
140 containing large files, generate a large file on output and
141 restore can restore them. This feature is not enabled by
142 default, use --enable-largefile option of configure to enable
143 it (you need to have a LFS aware glibc though). Thanks to
144 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
145 and to Theodore T'so <tytso@valinux.com> for his always
148 8. Made dump ask upon a tape write error if it should rewrite
149 the current volume (assume this is a bad tape) or if it should
150 assume an end-of-tape condition (useful for tape drives which
151 behaves badly at the end of the tape). Thanks to Andreas
152 Dilger <adilger@turbolinux.com> for the suggestion.
154 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
155 =======================================================================
157 1. Fixed a small compilation problem due to a change
158 in the definintion of the struct sigaction in
159 glibc 2.0 / libc5. Thanks to Gunther Schlegel
160 <schlegel@riege.de> for reporting the bug and to
161 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
164 2. Modified the label and uuid analysis in order to be
165 self-contained (independant of kernel/libc headers). This
166 should fix the compile with older kernel/libc headers and
167 will preserve the functionality. Thanks to Bernhard Erdmann
168 <bernhard.erdmann@gmx.de> for reporting the bug.
170 3. The 'exclude inode' option, if applied to a directory
171 inode, excludes now correctly all the leaves of this
172 directory. Thanks to John R. Dennison
173 <gerdesas@users.sourceforge.net> for reporting the bug.
175 4. Fixed the '-e' option to disable the possibility
176 to exclude the root inode (which causes the dumps to
177 be unreadable by restore). Prevented array overflow
178 when multiple -e options are used.
180 5. Fixed dump to correctly interpret a filesystem argument
181 which is a mountpoint and it is not an absolute path
182 (as specified in the fstab). Thanks to Bernhard R. Erdmann
183 <be@berdmann.de> for reporting the bug.
185 6. Made dump able to backup files larger than 2 GB. Note that
186 dump still doesn't cope with files larger than 4 GB.
188 7. Restore the real uid and gid before invoking an external
189 RSH program (big hole when dump or restore is suid root!).
191 8. Get the values for the default tape device and the location
192 of fstab file from the system headers. Thanks to
193 Andreas Dilger <adilger@turbolinux.com> for the patch.
195 9. Made dump -w|-W report all recognized filesystems
196 present in either /etc/fstab or /etc/dumpdates, and present
197 the list in the same order as in fstab file. Thanks
198 to Andreas Dilger <adilger@turbolinux.com> for the patch.
200 10. Made dump's -a (automatic end of tape detection) the
201 default. Specifying one of -B, -c, -d or -s options will
202 override the EOM detection. Thanks to Andreas Dilger
203 <adilger@turbolinux.com> for the patch.
205 11. Save the ext2 filesystem label into the dump volume label.
206 Specifying a volume label on the command line (-L option)
207 will override this feature. Thanks to Andreas Dilger
208 <adilger@turbolinux.com> for the patch.
210 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
211 =====================================================================
213 1. Fixed the signal handling in dump (which I broke in 0.4b17)
214 which was causing several strange dump failures (dump
215 hanged or segmentation faults etc).
217 2. Specified the default blocksize in the dump man page.
219 3. Changed two info messages of restore to be written on stdout
220 instead of stderr in order to leave stderr only for errors
221 or warnings. Thanks to Stephen Atwell
222 <satwell@urbana.css.mot.com> for the suggestion.
224 4. Corrected an off by one calculation which prevented
225 dumping a directory having a 1 character name length.
226 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
227 for reporting the bug.
229 5. Reinforce dump in order to allow only level 0 and no
230 -u option when dumping a subdirectory, and document
231 this in the man page. Thanks to Bernhard Erdmann
232 <bernhard.erdmann@gmx.de> for reporting the bug.
234 6. Fixed a small harmless bug in restore which caused
235 in some conditions hard links to be restored several
236 times (therefore generation some warning messages).
237 Thanks to Kenneth Porter <shiva@well.com> for
240 7. Updated the RPM spec file to the latest RedHat version,
241 providing FHS packaging and other cosmetic changes.
242 You will need RPM version >= 3.0.5 in order to build the RPM.
244 8. Updated the configure script to check for libtermcap
245 before checking for libreadline, because we need this
246 library in order to compile the readline support.
248 9. Made dump understand the LABEL= and UUID= notation
249 both in /etc/fstab and on the command line. Note that
250 you will need the /proc filesystem in order to use
251 these notations. Thanks to Erik Troan <ewt@redhat.com>
252 for providing the patch.
254 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
255 ===================================================================
257 1. Fixed a potential buffer overflow in restore. Thanks
258 to Stan Bubrouski <satan@fastdial.net> for reporting
261 2. Fixed a readline-related bug which prevented
262 'cat DUMPFILE | restore -i -f -' from working. Thanks
263 to Charles Karney <karney@users.sourceforge.net>
266 3. Changed a few "panic" into "exit", causing restore to
267 be more stable against some attacks (like the last one
268 reported on Bugtraq, although the last version of restore
269 was not vulnerable - just dumped core). Thanks to
270 Andreas Hasenack <andreas@conectiva.com.br> for reporting
273 4. Removed the suid-root bit on dump and restore in the
274 default build (and generated RPMs). It should be safer
275 now. Users who need the suid-root capabilities in order
276 to make network backups should read first the man page
277 of dump and enable the suid bit manually.
279 5. Added -ltermcap to the compile parameters for restore
280 when using readline support, in order to make the compile
281 process work on some systems (SuSE ?). Thanks to
282 Patrik Schindler <poc@pocnet.net> for reporting the bug.
284 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
285 ====================================================================
287 1. The -F script is called now *only* at the end of a tape,
288 not at the end of the dump. Thanks to Christian Haul
289 <haul@informatik.tu-darmstadt.de> for the bug report.
291 Normally, the device name and the current volume number
292 are passed on the command line of the script. However,
293 if you want the old style script (with no arguments
294 passed on the command line), you can enable it in
295 configure with the --enable-oldstylefscript.
297 2. Use posix signal handling to preserve dump functionality
298 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
301 3. Made the exit code of restore in case of a 'C'ompare
302 command reflect the result of the compare. An exit status
303 of 0 means the dump archive is correct, 1 means tape errors,
304 2 means that some files were modified. Thanks to Kenneth Porter
305 <shiva@well.com> for the suggestion.
307 4. Made (finally) quotes work in interactive restore.
309 5. Small fixes in order to allow dump to compile with a
310 really old e2fsprogs version. Thanks to Ian Zimmerman
311 <itz@speakeasy.org> for the bug report.
313 6. Add GNU readline capabilities to interactive restore.
314 Use configure's --enable-readline flag to enable this feature.
315 Thanks to Patrik Schindler <poc@pocnet.net> for the
318 7. Do the compare on the fly in restore 'C' mode (this will
319 allow not to exhaust the available /tmp space when
320 ccmparing large files). Thanks to Kenneth Porter
321 <shiva@well.com> for the suggestion.
323 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
324 ====================================================================
326 1. Fixed some several duplicate 'DUMP: DUMP:' in the
329 2. Corrected the estimation of blocks to dump. Note that
330 this is still wrong for large directory inodes, due
331 to the size of a BSD directory entry on the tape
332 (estimation is based on the size of the ext2 directory,
333 which is smaller because it doesn't contain the null
334 character at the end).
336 3. Made dump report the total number of MB written to
337 tape at the end of run. Thanks to W. Reilly Cooley
338 <wcooley@nakedape.cc> for the patch.
340 4. Added the -X option to restore giving the possibility
341 to read the names of the files to be extracted/listed
342 from a text file (in addition of the command line).
343 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
346 5. Added the device name and the current volume number
347 as arguments to the end of tape script (dump -F option).
349 6. Made the multi-volume dump work again (after having
350 broken it in 0.4b15).
352 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
353 ===================================================================
355 1. Added a prompt command in interactive restore mode. Thanks
356 to Andreas Dilger <adilger@home.com> for the patch.
358 2. Fixed a buffer overflow problem in dump (caused by
359 not checking the size of the filesystem parameter).
360 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
361 reporting this on Bugtraq (and to several dump users
362 who forwarded me his mail).
364 3. Added the '-F script' option to dump in order to
365 launch a script at the end of each tape (to be used
366 with a tape changer, or to notify the sysadmin by
369 4. Fixed a bug in restore compare code caused by the changes
372 5. Fixed the treatment of options using the old BSD syntax
373 in both dump and restore.
375 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
376 =======================================================================
378 1. Fixed a bug in dump which may have caused invalid deleted
379 directories to be dumped out if they were deleted after the
380 mapping pass. This could occure on active filesystem and lead
381 to heap corruption (causing dump malfunction in many possible ways).
382 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
383 bug and submitting the patch.
385 2. Fixed the handling of the filesystem parameter in dump. A
386 '/mnt/disk' parameter caused the disk contents to be dumped,
387 but a '/mnt/disk/' parameter caused the mountpoint directory
388 to be dumped (generally an empty directory).
390 3. Improved the output of dump in order to tell which directory
391 it is currently dumping (when dumping a subtree).
393 4. Added the '-e' exclude inode option to dump. Thanks to
394 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
396 5. Added a REPORTING-BUGS file in order to provide a guide
397 on how to correctly report a bug in dump/restore.
399 6. Fixed a restore problem when restoring a hard link to an inode
400 having the immutable or append-only attribute set. Thanks to
401 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
403 7. Fixed a compatibility problem between dumps made on little
404 endian machines (the format was correct) and big endian
405 machines (the format was incorrect). This fix break the
406 compatibility with the older dumps made on big endian
407 machines (sparc, m86k, ppc etc). For the first time in
408 linux dump's history (I believe), the dumps made by *BSD,
409 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
410 so interchangeable. Thanks to Rob Cermak
411 <cermak@ahab.rutgers.edu> for submitting the bug and
412 helping me test the fix.
414 8. Fixed the way dump reports the remaining percent/time, if
415 the number of blocks actually dumped exceeds the estimated
416 number of blocks. Thanks to Jean-Paul van der Jagt
417 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
419 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
420 ======================================================================
422 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
423 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
425 2. Removed the requirement to build the RPM as root from the
426 spec file. Thanks to Christian Weisgerber
427 <naddy@mips.rhein-neckar.de> for submitting this.
429 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
430 causing dump to block when dumping really huge filesystems.
431 Many thanks to Patrik Schindler <poc@pocnet.net> for
432 helping me find this bug.
434 4. Fixed the treatment for an interrupt signal when dump access
435 the remote tape through RSH. Thanks to Christian Weisgerber
436 <naddy@mips.rhein-neckar.de> for providing the patch.
438 5. Fixed a bug which was causing dump/restore to display
439 garbage characters instead of the remote host name.
441 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
442 =====================================================================
444 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
445 <kukuk@suse.de> for submitting the patch.
447 2. Fix for the exit code when using the size estimate option of
448 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
449 submitting the patch.
451 3. Handle EINTR in atomical reads/writes in dump, which was causing
452 dump to fail on some systems. Thanks to Eric Jergensen
453 <eric@dvns.com> for reporting the bug and submitting the patch.
455 4. Handle more than 16 characters for the device names in dumpdates.
456 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
457 tracking down the problem and proposing the solution.
459 5. Fixed a bug in dump which prevented the creation of the
460 dumpdates file when doing a 0-level dump without already
461 having a dumpdates file. Thanks to Patrik Schindler
462 <poc@pocnet.net> for reporting the bug.
464 6. Changed the way dump 'S' flag reports the size estimate
465 from number of blocks into bytes (making it compatible
466 with the Solaris version, and simplifying things for
467 amanda users). Thanks to Jason L Tibbitts III
468 <tibbs@math.uh.edu> for reporting the bug.
470 7. Fixed a compatibility problem in linux/alpha dump tape format.
471 Now the linux/alpha dump are (again) compatible with the
472 other dump formats. But this breaks compatibility with
473 older dumps made on alpha. Thanks to Mike Tibor
474 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
476 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
477 ======================================================================
479 1. Added a '--enable-kerberos' to configure.
481 2. Added a 'S' option to dump which determines the amount of space
482 that is needed to perform the dump without actually doing it, similar
483 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
484 <cermak@ahab.rutgers.edu>.
486 3. Added a 'M' multi-volume option to dump and restore which enables
487 dumping to multiple files (useful when dumping to an ext2
488 partition to make several dump files in order to bypass the 2GB
489 file size limitation). The 'f' argument is treated as a prefix and
490 the output files will be named <prefix>001, <prefix>002 etc. With
491 the 'M' flag, restore automatically selects the right file without
492 asking to enter a new tape each time.
494 4. Fixed a memory leak which was causing dump to grow very big
495 (270MB when dumping a 10GB filesystem...). Thanks to Jason
496 Fearon <jasonf@netrider.org.au> for reporting the bug.
498 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
499 ======================================================================
501 1. Make configure test if the system glob routines support
502 extended syntax (ALTDIRFUNC). If not, use the internal glob
503 routines instead of system ones. Thanks to Bernhard Sadlowski
504 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
505 and helping me resolve this and other minor libc5 compiling
508 2. Fix a problem when dumping a ext2fs with the 'filetype'
509 feature enabled. Thanks to Patrick J. LoPresti
510 <patl@cag.lcs.mit.edu> for reporting the bug and to
511 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
513 3. Made the nodump flag work on directories. A directory which
514 has the nodump flag gets never dumped, regardless of its
517 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
518 which allows dump on an active ext3 filesystem. However, this
519 is a "quick and dirty" patch which enables backup of an ext3
520 filesystem through the ext2 compatibility (by ignoring the
521 NEEDS_RECOVERY bit). The journal file is not recognized and
522 it is dumped (it should not).
524 5. Test the superblock compatibility flags when dumping, in order
525 to be sure that we know how to deal with specific features.
527 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
528 ====================================================================
530 1. Use lchown instead of chown, fixing a possible security problem
531 when restoring symlinks (a malicious user could use this
532 to deliberately corrupt the ownership of important system files).
533 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
534 this and providing the patch.
536 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
537 ====================================================================
539 1. Put dump sources under CVS, added Id tags in all files so
540 one can use 'ident' on binary files.
542 2. Added the dump/restore version in the usage text so one can
543 easily verify the version he is using.
545 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
546 a va_start/va_end problem on linux-ppc (always call va_start
547 va_end in pairs each time we use a vararg function).
549 4. Added again the DT_* constants because old libc does not
550 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
551 for submitting the bug report.
553 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
554 this should enable dumping big (huge) filesystems.
556 6. Added the RSH environment variable in order to be able to
557 use a rsh replacement like ssh when doing remote backups (and
558 bypass the security limitations of rcmd). Now you can do remote
559 backups without being root (or making dump setuid root).
561 7. Modified again the way dumpdates works. For incremental dumps,
562 we need to read dumpdates even if we are not using 'u' option.

566 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
567 ===================================================================
569 1. Removed the 'k' flag from the restore 'about' text if kerberos
572 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
573 to them (fsetflags takes a char*, setflags an open fd!).
575 3. (f)setflags is called only if the flags aren't empty. If the
576 file is a special file, a warning is printed, because changing
577 flags implies opening the device. Normally, a special file
578 should not have any flag... (Debian bug #29775, patch provided
579 by Abhijit Dasgupta <abhijit@ans.net>).
581 4. Made possible to dump a file system not mentioned in /etc/fstab.
582 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
584 5. Changed the default behaviour to not create dumpdates
585 unless 'u' option is specified. Removed the old "debian-patch"
586 which provided the same thing. (Debian bug #38136, #33818).
588 6. Removed all those dump*announce, since they were getting old...
590 7. Added warning messages if dumpdates does not exist and
591 when an inferior level dump does not exist (except for a level 0
594 8. Debugged the glob calls in interactive mode: restore used a
595 dirent struct which was different from the /usr/include/dirent.h
596 one (this used to work, is it a glibc2 change?), so none of the
597 compat glob (which used /usr/include/dirent.h) or the system glob
598 worked. Restore use now the system dirent (and the system
599 DT_* constants), which are compatible with BSD ones.
601 9. Added a configure flag (--with-dumpdatespath) to specify
602 the location of dumpdates file. By default, it is
605 10. Added the "AUTHOR" and "AVAILABILITY" sections and
606 included the current date/version in man pages.
608 11. Corrected the estimation of remaining time when
609 the operator doesn't change the tapes quickly enough. This
610 was an old bug, I thought I corrected it, and discovered
611 that in fact it was corrected in two different places, so
612 the results canceled each other...
614 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
615 ===================================================================
617 1. Integrated multiple patches from RedHat, Debian and SuSE:
619 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
621 - several fixes in the man pages.
622 - update the default tape device to /dev/st0.
623 - many updates for Linux Alpha (byte ordering, size_t etc).
625 - use environment variable for TMPDIR (instead of /tmp).
626 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
627 - workaround egcs bug (RedHat bugs #4281 and #2989).
628 - wire $(OPT) throughout Makefile's.
630 2. Upgrade the dump revision to 1, making possible to dump filesystems
631 made with e2fsprogs-1.15 or newer. Nothing seems to break...
633 3. Fix some compile warnings, prototype all functions.
635 4. Use glibc err/glob instead of internal compatibility
636 routines (only if available).
638 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
639 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
641 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
642 ======================================================================
644 1. Integrated the changes from FreeBSD-3.1-RELEASE
645 (mostly bug fixes, buffer overruns, dump has now an "automatic
646 tape length calculation" flag, dump/restore can use kerberos now
647 (this is NOT tested), use environment variables for TAPE and
650 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
652 3. Corrected a bug in restore when using 'C' option with multi-volumes
653 tapes (files splited accros two tapes give "size changed" errors
656 4. Corrected the long standing bug when dumping multiple tapes.
657 This works for me, needs further testing.
659 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
660 ====================================================================
662 1. Dump now runs correctly on kernels 2.1.x
663 Fix made by Gerald Peters <gapeters@worldnet.att.net>
665 Changes between versions 0.4b2 and 0.4b3
666 ========================================
668 1. Use realpath() if available
672 Changes between versions 0.4b1 and 0.4b2
673 ========================================
675 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
678 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
680 3. Fixed configure.in to correctly handle --enable-rmt
682 Changes between versions 0.3 and 0.4b1
683 ======================================
685 1. Integrated the changes from 4.4BSD-Lite2
687 2. Integrated the patches from Debian and Red Hat
689 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
691 4. Changed dump to use the Ext2fs library to get block addresses. This
692 should solve the endianness problem on SparcLinux.
694 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
695 distribution's one) to use autoconf
697 6. Fixed a few minor bugs
699 Changes between versions 0.2e and 0.2f
700 ======================================
702 1. Added the creation of named pipes (fifos) in restore.
704 2. Added the -N flag in the restore manual page.
706 3. Added the file kernel.patch which contains the llseek() optimization
707 patch for 1.2.x kernels.
709 4. Fixed a bug in the restoration of symbolic links: owner and group were
712 5. Integrated some changes from FreeBSD 2.2.
714 6. Added a call to ftruncate() after restoring each file to restore
715 correctly files ending by a hole.
717 Changes between versions 0.2d and 0.2e
718 ======================================
720 1. Fixed a bug in the "set owner/mode" process. Every file was restored
721 with owner = root (0) and group = root/wheel/whatever (0).
723 Changes between versions 0.2c and 0.2d
724 ======================================
726 1. Dump is now able to backup 2GB+ filesystems.
728 2. Dump and restore can now be linked as static binaries.
730 Changes between versions 0.2b and 0.2c
731 ======================================
733 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
735 Changes between versions 0.2a and 0.2b
736 ======================================
738 1. Really fixed the bug that I should have corrected in 0.2a.
740 2. Enabled optimization again.
742 Changes between versions 0.2 and 0.2a
743 =====================================
745 1. Disabled the optimization during compilation.
747 Changes between versions 0.1 and 0.2
748 ====================================
750 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
751 the fs_type field (actually, I modified the file fstab.c to make it
752 use the mntent functions).
754 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
755 made by dump should be readable by the BSD restore and backups made
756 by the BSD dump should be readable by restore. Unfortunately, this
757 means that the dump format has changed between version 0.1 and version
760 3. Dump is now able to backup a subtree, it is no longer limited to whole
761 filesystems like the BSD version.
763 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
766 Changes between versions 0.0 and 0.1
767 ====================================
769 1. Now create links rdump and rrestore during the `make install' step.
771 2. Linux port specific bugs added to the manual pages
773 3. Incorrect estimation of the number of tapes blocks fixed when doing
776 4. Better ls-like format in restore in interactive mode.
