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 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
18 ==================================================================
20 1. Made dump report the number of blocks dumped per volume.
21 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
23 2. Fix a bug in dump where waiting too much at the 'change volumes'
24 question caused the volume to be rewritten. Thanks to
25 Graham Reed <greed@users.sourceforge.net> for reporting the
26 bug and providing a patch.
28 3. Added a compression option to dump, contributed by Jerry
29 Peters <gapeters@worldnet.att.net>.
31 WARNING: the compression works only on files/pipes and
32 drives supporting variable block size.
34 WARNING2: tapes created using the compression feature are
35 incompatible with the standard dump tape format, and a
36 version of restore >= 0.4b22 will be needed for extraction.
38 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
39 architectures. Thanks to Paul Slootman <paul@debian.org> for
40 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
43 5. Many cleanups (CPP defines, const char warnings, check of
44 ext2fs COMPAT flags, time_t cleanups, added libext2 version
45 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
47 6. Made --prefix option work in configure. All the install path
48 are now based on the configure parameters.
50 7. Added the Quick File Access mode in dump/restore, contributed
51 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
52 a file tape position for each inode, and this file is used by
53 restore (if called with parameter Q and the filename)
54 to directly position the tape at the file restore is currently
55 working on. This saves hours when restoring single files from
56 large backups, saves the tapes and the drive's head. Use
57 --enable-qfa option of configure to compile in the QFA support.
59 8. Added the possibility to dump several files and directories
60 in a single invocation of dump. Thanks to Uwe Gohlke
61 <uwe@ugsoft.de> for implementing this option.
63 9. Fixed the dumping and restoring of files with holes
64 (files ending with holes didn't get dumped or restored
67 10. Fixed a socket descriptor leak in dump, which leaved opened
68 3 file descriptors per dump process (and there is one dump
71 11. Fixed dump large file system support, by explicit use of
72 open64/lseek64/etc functions (explicit use needed because
73 e2fsprogs libraries don't behave well when compiled with
76 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
77 ======================================================================
79 1. Fixed some bugs in the dump -w|-W logic introduced by
80 the previous version. Thanks to Andreas Dilger
81 <adilger@turbolinux.com> for his help on this one.
83 2. Fixed again a compilation problem when using old e2fs
84 headers (filesystem label related). Thanks to many users
85 who reported this stupid error.
87 3. Fixed a build problem on old lib5 based systems dealing with
88 _PATH_MNTTAB being undefined. Thanks to John Adams
89 <johna@onevista.com> for reporting the bug.
91 4. Improved the error detection in restore when creating
92 the temporary files in TMPDIR. Now restore will corectly
93 report a 'no space left on device' error instead of
94 strange errors which could imply an archive corruption.
95 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
96 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
98 5. Added the throughput information in dump's progression
99 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
102 6. Use libext2fs's inode scanning routines, which are particularly
103 robust when dealing with errors (especially when having some
104 bad blocks on the filesystem). Many thanks to Colin
105 <colin@horizon.com> for reporting the bug, investigating
106 the issues, finding a workaround, writing the patch and
107 fully testing it... (of course, if this patch will break
108 anything, he is to blame for :-)).
110 7. Made dump and restore LFS aware. Dump can dump a filesystem
111 containing large files, generate a large file on output and
112 restore can restore them. This feature is not enabled by
113 default, use --enable-largefile option of configure to enable
114 it (you need to have a LFS aware glibc though). Thanks to
115 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
116 and to Theodore T'so <tytso@valinux.com> for his always
119 8. Made dump ask upon a tape write error if it should rewrite
120 the current volume (assume this is a bad tape) or if it should
121 assume an end-of-tape condition (useful for tape drives which
122 behaves badly at the end of the tape). Thanks to Andreas
123 Dilger <adilger@turbolinux.com> for the suggestion.
125 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
126 =======================================================================
128 1. Fixed a small compilation problem due to a change
129 in the definintion of the struct sigaction in
130 glibc 2.0 / libc5. Thanks to Gunther Schlegel
131 <schlegel@riege.de> for reporting the bug and to
132 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
135 2. Modified the label and uuid analysis in order to be
136 self-contained (independant of kernel/libc headers). This
137 should fix the compile with older kernel/libc headers and
138 will preserve the functionality. Thanks to Bernhard Erdmann
139 <bernhard.erdmann@gmx.de> for reporting the bug.
141 3. The 'exclude inode' option, if applied to a directory
142 inode, excludes now correctly all the leaves of this
143 directory. Thanks to John R. Dennison
144 <gerdesas@users.sourceforge.net> for reporting the bug.
146 4. Fixed the '-e' option to disable the possibility
147 to exclude the root inode (which causes the dumps to
148 be unreadable by restore). Prevented array overflow
149 when multiple -e options are used.
151 5. Fixed dump to correctly interpret a filesystem argument
152 which is a mountpoint and it is not an absolute path
153 (as specified in the fstab). Thanks to Bernhard R. Erdmann
154 <be@berdmann.de> for reporting the bug.
156 6. Made dump able to backup files larger than 2 GB. Note that
157 dump still doesn't cope with files larger than 4 GB.
159 7. Restore the real uid and gid before invoking an external
160 RSH program (big hole when dump or restore is suid root!).
162 8. Get the values for the default tape device and the location
163 of fstab file from the system headers. Thanks to
164 Andreas Dilger <adilger@turbolinux.com> for the patch.
166 9. Made dump -w|-W report all recognized filesystems
167 present in either /etc/fstab or /etc/dumpdates, and present
168 the list in the same order as in fstab file. Thanks
169 to Andreas Dilger <adilger@turbolinux.com> for the patch.
171 10. Made dump's -a (automatic end of tape detection) the
172 default. Specifying one of -B, -c, -d or -s options will
173 override the EOM detection. Thanks to Andreas Dilger
174 <adilger@turbolinux.com> for the patch.
176 11. Save the ext2 filesystem label into the dump volume label.
177 Specifying a volume label on the command line (-L option)
178 will override this feature. Thanks to Andreas Dilger
179 <adilger@turbolinux.com> for the patch.
181 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
182 =====================================================================
184 1. Fixed the signal handling in dump (which I broke in 0.4b17)
185 which was causing several strange dump failures (dump
186 hanged or segmentation faults etc).
188 2. Specified the default blocksize in the dump man page.
190 3. Changed two info messages of restore to be written on stdout
191 instead of stderr in order to leave stderr only for errors
192 or warnings. Thanks to Stephen Atwell
193 <satwell@urbana.css.mot.com> for the suggestion.
195 4. Corrected an off by one calculation which prevented
196 dumping a directory having a 1 character name length.
197 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
198 for reporting the bug.
200 5. Reinforce dump in order to allow only level 0 and no
201 -u option when dumping a subdirectory, and document
202 this in the man page. Thanks to Bernhard Erdmann
203 <bernhard.erdmann@gmx.de> for reporting the bug.
205 6. Fixed a small harmless bug in restore which caused
206 in some conditions hard links to be restored several
207 times (therefore generation some warning messages).
208 Thanks to Kenneth Porter <shiva@well.com> for
211 7. Updated the RPM spec file to the latest RedHat version,
212 providing FHS packaging and other cosmetic changes.
213 You will need RPM version >= 3.0.5 in order to build the RPM.
215 8. Updated the configure script to check for libtermcap
216 before checking for libreadline, because we need this
217 library in order to compile the readline support.
219 9. Made dump understand the LABEL= and UUID= notation
220 both in /etc/fstab and on the command line. Note that
221 you will need the /proc filesystem in order to use
222 these notations. Thanks to Erik Troan <ewt@redhat.com>
223 for providing the patch.
225 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
226 ===================================================================
228 1. Fixed a potential buffer overflow in restore. Thanks
229 to Stan Bubrouski <satan@fastdial.net> for reporting
232 2. Fixed a readline-related bug which prevented
233 'cat DUMPFILE | restore -i -f -' from working. Thanks
234 to Charles Karney <karney@users.sourceforge.net>
237 3. Changed a few "panic" into "exit", causing restore to
238 be more stable against some attacks (like the last one
239 reported on Bugtraq, although the last version of restore
240 was not vulnerable - just dumped core). Thanks to
241 Andreas Hasenack <andreas@conectiva.com.br> for reporting
244 4. Removed the suid-root bit on dump and restore in the
245 default build (and generated RPMs). It should be safer
246 now. Users who need the suid-root capabilities in order
247 to make network backups should read first the man page
248 of dump and enable the suid bit manually.
250 5. Added -ltermcap to the compile parameters for restore
251 when using readline support, in order to make the compile
252 process work on some systems (SuSE ?). Thanks to
253 Patrik Schindler <poc@pocnet.net> for reporting the bug.
255 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
256 ====================================================================
258 1. The -F script is called now *only* at the end of a tape,
259 not at the end of the dump. Thanks to Christian Haul
260 <haul@informatik.tu-darmstadt.de> for the bug report.
262 Normally, the device name and the current volume number
263 are passed on the command line of the script. However,
264 if you want the old style script (with no arguments
265 passed on the command line), you can enable it in
266 configure with the --enable-oldstylefscript.
268 2. Use posix signal handling to preserve dump functionality
269 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
272 3. Made the exit code of restore in case of a 'C'ompare
273 command reflect the result of the compare. An exit status
274 of 0 means the dump archive is correct, 1 means tape errors,
275 2 means that some files were modified. Thanks to Kenneth Porter
276 <shiva@well.com> for the suggestion.
278 4. Made (finally) quotes work in interactive restore.
280 5. Small fixes in order to allow dump to compile with a
281 really old e2fsprogs version. Thanks to Ian Zimmerman
282 <itz@speakeasy.org> for the bug report.
284 6. Add GNU readline capabilities to interactive restore.
285 Use configure's --enable-readline flag to enable this feature.
286 Thanks to Patrik Schindler <poc@pocnet.net> for the
289 7. Do the compare on the fly in restore 'C' mode (this will
290 allow not to exhaust the available /tmp space when
291 ccmparing large files). Thanks to Kenneth Porter
292 <shiva@well.com> for the suggestion.
294 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
295 ====================================================================
297 1. Fixed some several duplicate 'DUMP: DUMP:' in the
300 2. Corrected the estimation of blocks to dump. Note that
301 this is still wrong for large directory inodes, due
302 to the size of a BSD directory entry on the tape
303 (estimation is based on the size of the ext2 directory,
304 which is smaller because it doesn't contain the null
305 character at the end).
307 3. Made dump report the total number of MB written to
308 tape at the end of run. Thanks to W. Reilly Cooley
309 <wcooley@nakedape.cc> for the patch.
311 4. Added the -X option to restore giving the possibility
312 to read the names of the files to be extracted/listed
313 from a text file (in addition of the command line).
314 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
317 5. Added the device name and the current volume number
318 as arguments to the end of tape script (dump -F option).
320 6. Made the multi-volume dump work again (after having
321 broken it in 0.4b15).
323 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
324 ===================================================================
326 1. Added a prompt command in interactive restore mode. Thanks
327 to Andreas Dilger <adilger@home.com> for the patch.
329 2. Fixed a buffer overflow problem in dump (caused by
330 not checking the size of the filesystem parameter).
331 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
332 reporting this on Bugtraq (and to several dump users
333 who forwarded me his mail).
335 3. Added the '-F script' option to dump in order to
336 launch a script at the end of each tape (to be used
337 with a tape changer, or to notify the sysadmin by
340 4. Fixed a bug in restore compare code caused by the changes
343 5. Fixed the treatment of options using the old BSD syntax
344 in both dump and restore.
346 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
347 =======================================================================
349 1. Fixed a bug in dump which may have caused invalid deleted
350 directories to be dumped out if they were deleted after the
351 mapping pass. This could occure on active filesystem and lead
352 to heap corruption (causing dump malfunction in many possible ways).
353 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
354 bug and submitting the patch.
356 2. Fixed the handling of the filesystem parameter in dump. A
357 '/mnt/disk' parameter caused the disk contents to be dumped,
358 but a '/mnt/disk/' parameter caused the mountpoint directory
359 to be dumped (generally an empty directory).
361 3. Improved the output of dump in order to tell which directory
362 it is currently dumping (when dumping a subtree).
364 4. Added the '-e' exclude inode option to dump. Thanks to
365 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
367 5. Added a REPORTING-BUGS file in order to provide a guide
368 on how to correctly report a bug in dump/restore.
370 6. Fixed a restore problem when restoring a hard link to an inode
371 having the immutable or append-only attribute set. Thanks to
372 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
374 7. Fixed a compatibility problem between dumps made on little
375 endian machines (the format was correct) and big endian
376 machines (the format was incorrect). This fix break the
377 compatibility with the older dumps made on big endian
378 machines (sparc, m86k, ppc etc). For the first time in
379 linux dump's history (I believe), the dumps made by *BSD,
380 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
381 so interchangeable. Thanks to Rob Cermak
382 <cermak@ahab.rutgers.edu> for submitting the bug and
383 helping me test the fix.
385 8. Fixed the way dump reports the remaining percent/time, if
386 the number of blocks actually dumped exceeds the estimated
387 number of blocks. Thanks to Jean-Paul van der Jagt
388 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
390 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
391 ======================================================================
393 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
394 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
396 2. Removed the requirement to build the RPM as root from the
397 spec file. Thanks to Christian Weisgerber
398 <naddy@mips.rhein-neckar.de> for submitting this.
400 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
401 causing dump to block when dumping really huge filesystems.
402 Many thanks to Patrik Schindler <poc@pocnet.net> for
403 helping me find this bug.
405 4. Fixed the treatment for an interrupt signal when dump access
406 the remote tape through RSH. Thanks to Christian Weisgerber
407 <naddy@mips.rhein-neckar.de> for providing the patch.
409 5. Fixed a bug which was causing dump/restore to display
410 garbage characters instead of the remote host name.
412 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
413 =====================================================================
415 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
416 <kukuk@suse.de> for submitting the patch.
418 2. Fix for the exit code when using the size estimate option of
419 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
420 submitting the patch.
422 3. Handle EINTR in atomical reads/writes in dump, which was causing
423 dump to fail on some systems. Thanks to Eric Jergensen
424 <eric@dvns.com> for reporting the bug and submitting the patch.
426 4. Handle more than 16 characters for the device names in dumpdates.
427 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
428 tracking down the problem and proposing the solution.
430 5. Fixed a bug in dump which prevented the creation of the
431 dumpdates file when doing a 0-level dump without already
432 having a dumpdates file. Thanks to Patrik Schindler
433 <poc@pocnet.net> for reporting the bug.
435 6. Changed the way dump 'S' flag reports the size estimate
436 from number of blocks into bytes (making it compatible
437 with the Solaris version, and simplifying things for
438 amanda users). Thanks to Jason L Tibbitts III
439 <tibbs@math.uh.edu> for reporting the bug.
441 7. Fixed a compatibility problem in linux/alpha dump tape format.
442 Now the linux/alpha dump are (again) compatible with the
443 other dump formats. But this breaks compatibility with
444 older dumps made on alpha. Thanks to Mike Tibor
445 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
447 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
448 ======================================================================
450 1. Added a '--enable-kerberos' to configure.
452 2. Added a 'S' option to dump which determines the amount of space
453 that is needed to perform the dump without actually doing it, similar
454 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
455 <cermak@ahab.rutgers.edu>.
457 3. Added a 'M' multi-volume option to dump and restore which enables
458 dumping to multiple files (useful when dumping to an ext2
459 partition to make several dump files in order to bypass the 2GB
460 file size limitation). The 'f' argument is treated as a prefix and
461 the output files will be named <prefix>001, <prefix>002 etc. With
462 the 'M' flag, restore automatically selects the right file without
463 asking to enter a new tape each time.
465 4. Fixed a memory leak which was causing dump to grow very big
466 (270MB when dumping a 10GB filesystem...). Thanks to Jason
467 Fearon <jasonf@netrider.org.au> for reporting the bug.
469 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
470 ======================================================================
472 1. Make configure test if the system glob routines support
473 extended syntax (ALTDIRFUNC). If not, use the internal glob
474 routines instead of system ones. Thanks to Bernhard Sadlowski
475 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
476 and helping me resolve this and other minor libc5 compiling
479 2. Fix a problem when dumping a ext2fs with the 'filetype'
480 feature enabled. Thanks to Patrick J. LoPresti
481 <patl@cag.lcs.mit.edu> for reporting the bug and to
482 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
484 3. Made the nodump flag work on directories. A directory which
485 has the nodump flag gets never dumped, regardless of its
488 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
489 which allows dump on an active ext3 filesystem. However, this
490 is a "quick and dirty" patch which enables backup of an ext3
491 filesystem through the ext2 compatibility (by ignoring the
492 NEEDS_RECOVERY bit). The journal file is not recognized and
493 it is dumped (it should not).
495 5. Test the superblock compatibility flags when dumping, in order
496 to be sure that we know how to deal with specific features.
498 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
499 ====================================================================
501 1. Use lchown instead of chown, fixing a possible security problem
502 when restoring symlinks (a malicious user could use this
503 to deliberately corrupt the ownership of important system files).
504 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
505 this and providing the patch.
507 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
508 ====================================================================
510 1. Put dump sources under CVS, added Id tags in all files so
511 one can use 'ident' on binary files.
513 2. Added the dump/restore version in the usage text so one can
514 easily verify the version he is using.
516 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
517 a va_start/va_end problem on linux-ppc (always call va_start
518 va_end in pairs each time we use a vararg function).
520 4. Added again the DT_* constants because old libc does not
521 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
522 for submitting the bug report.
524 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
525 this should enable dumping big (huge) filesystems.
527 6. Added the RSH environment variable in order to be able to
528 use a rsh replacement like ssh when doing remote backups (and
529 bypass the security limitations of rcmd). Now you can do remote
530 backups without being root (or making dump setuid root).
532 7. Modified again the way dumpdates works. For incremental dumps,
533 we need to read dumpdates even if we are not using 'u' option.
534 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
537 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
538 ===================================================================
540 1. Removed the 'k' flag from the restore 'about' text if kerberos
543 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
544 to them (fsetflags takes a char*, setflags an open fd!).
546 3. (f)setflags is called only if the flags aren't empty. If the
547 file is a special file, a warning is printed, because changing
548 flags implies opening the device. Normally, a special file
549 should not have any flag... (Debian bug #29775, patch provided
550 by Abhijit Dasgupta <abhijit@ans.net>).
552 4. Made possible to dump a file system not mentioned in /etc/fstab.
553 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
555 5. Changed the default behaviour to not create dumpdates
556 unless 'u' option is specified. Removed the old "debian-patch"
557 which provided the same thing. (Debian bug #38136, #33818).
559 6. Removed all those dump*announce, since they were getting old...
561 7. Added warning messages if dumpdates does not exist and
562 when an inferior level dump does not exist (except for a level 0
565 8. Debugged the glob calls in interactive mode: restore used a
566 dirent struct which was different from the /usr/include/dirent.h
567 one (this used to work, is it a glibc2 change?), so none of the
568 compat glob (which used /usr/include/dirent.h) or the system glob
569 worked. Restore use now the system dirent (and the system
570 DT_* constants), which are compatible with BSD ones.
572 9. Added a configure flag (--with-dumpdatespath) to specify
573 the location of dumpdates file. By default, it is
576 10. Added the "AUTHOR" and "AVAILABILITY" sections and
577 included the current date/version in man pages.
579 11. Corrected the estimation of remaining time when
580 the operator doesn't change the tapes quickly enough. This
581 was an old bug, I thought I corrected it, and discovered
582 that in fact it was corrected in two different places, so
583 the results canceled each other...
585 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
586 ===================================================================
588 1. Integrated multiple patches from RedHat, Debian and SuSE:
590 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
592 - several fixes in the man pages.
593 - update the default tape device to /dev/st0.
594 - many updates for Linux Alpha (byte ordering, size_t etc).
596 - use environment variable for TMPDIR (instead of /tmp).
597 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
598 - workaround egcs bug (RedHat bugs #4281 and #2989).
599 - wire $(OPT) throughout Makefile's.
601 2. Upgrade the dump revision to 1, making possible to dump filesystems
602 made with e2fsprogs-1.15 or newer. Nothing seems to break...
604 3. Fix some compile warnings, prototype all functions.
606 4. Use glibc err/glob instead of internal compatibility
607 routines (only if available).
609 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
610 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
612 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
613 ======================================================================
615 1. Integrated the changes from FreeBSD-3.1-RELEASE
616 (mostly bug fixes, buffer overruns, dump has now an "automatic
617 tape length calculation" flag, dump/restore can use kerberos now
618 (this is NOT tested), use environment variables for TAPE and
621 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
623 3. Corrected a bug in restore when using 'C' option with multi-volumes
624 tapes (files splited accros two tapes give "size changed" errors
627 4. Corrected the long standing bug when dumping multiple tapes.
628 This works for me, needs further testing.
630 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
631 ====================================================================
633 1. Dump now runs correctly on kernels 2.1.x
634 Fix made by Gerald Peters <gapeters@worldnet.att.net>
636 Changes between versions 0.4b2 and 0.4b3
637 ========================================
639 1. Use realpath() if available
643 Changes between versions 0.4b1 and 0.4b2
644 ========================================
646 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
649 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
651 3. Fixed configure.in to correctly handle --enable-rmt
653 Changes between versions 0.3 and 0.4b1
654 ======================================
656 1. Integrated the changes from 4.4BSD-Lite2
658 2. Integrated the patches from Debian and Red Hat
660 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
662 4. Changed dump to use the Ext2fs library to get block addresses. This
663 should solve the endianness problem on SparcLinux.
665 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
666 distribution's one) to use autoconf
668 6. Fixed a few minor bugs
670 Changes between versions 0.2e and 0.2f
671 ======================================
673 1. Added the creation of named pipes (fifos) in restore.
675 2. Added the -N flag in the restore manual page.
677 3. Added the file kernel.patch which contains the llseek() optimization
678 patch for 1.2.x kernels.
680 4. Fixed a bug in the restoration of symbolic links: owner and group were
683 5. Integrated some changes from FreeBSD 2.2.
685 6. Added a call to ftruncate() after restoring each file to restore
686 correctly files ending by a hole.
688 Changes between versions 0.2d and 0.2e
689 ======================================
691 1. Fixed a bug in the "set owner/mode" process. Every file was restored
692 with owner = root (0) and group = root/wheel/whatever (0).
694 Changes between versions 0.2c and 0.2d
695 ======================================
697 1. Dump is now able to backup 2GB+ filesystems.
699 2. Dump and restore can now be linked as static binaries.
701 Changes between versions 0.2b and 0.2c
702 ======================================
704 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
706 Changes between versions 0.2a and 0.2b
707 ======================================
709 1. Really fixed the bug that I should have corrected in 0.2a.
711 2. Enabled optimization again.
713 Changes between versions 0.2 and 0.2a
714 =====================================
716 1. Disabled the optimization during compilation.
718 Changes between versions 0.1 and 0.2
719 ====================================
721 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
722 the fs_type field (actually, I modified the file fstab.c to make it
723 use the mntent functions).
725 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
726 made by dump should be readable by the BSD restore and backups made
727 by the BSD dump should be readable by restore. Unfortunately, this
728 means that the dump format has changed between version 0.1 and version
731 3. Dump is now able to backup a subtree, it is no longer limited to whole
732 filesystems like the BSD version.
734 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
737 Changes between versions 0.0 and 0.1
738 ====================================
740 1. Now create links rdump and rrestore during the `make install' step.
742 2. Linux port specific bugs added to the manual pages
744 3. Incorrect estimation of the number of tapes blocks fixed when doing
747 4. Better ls-like format in restore in interactive mode.
