3 | Changes between versions 0.4b16 and 0.4b17 (released ??????????????) | |
4 | ==================================================================== | |
5 | ||
6 | 1. The -F script is called now *only* at the end of a tape, | |
7 | not at the end of the dump. Thanks to Chris | |
8 | <haul@informatik.tu-darmstadt.de> for the bug report. | |
9 | ||
10 | 2. Use posix signal handling to preserve dump functionality | |
11 | with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for | |
12 | the patch. | |

107a347c SP |
14 | Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) |
15 | ==================================================================== | |
d65ed175 SP |
16 | |
17 | 1. Fixed some several duplicate 'DUMP: DUMP:' in the | |
18 | output of dump. | |
d3393043 | 19 | |
cbc94239 SP |
20 | 2. Corrected the estimation of blocks to dump. Note that |
21 | this is still wrong for large directory inodes, due | |
22 | to the size of a BSD directory entry on the tape | |
23 | (estimation is based on the size of the ext2 directory, | |
24 | which is smaller because it doesn't contain the null | |
25 | character at the end). | |
26 | ||
27 | 3. Made dump report the total number of MB written to | |
28 | tape at the end of run. Thanks to W. Reilly Cooley | |
29 | <wcooley@nakedape.cc> for the patch. | |
30 | ||
08db2b86 SP |
31 | 4. Added the -X option to restore giving the possibility |
32 | to read the names of the files to be extracted/listed | |
1a05d45d SP |
33 | from a text file (in addition of the command line). |
34 | Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the | |
35 | patch. | |
08db2b86 | 36 | |
365a7c7c SP |
37 | 5. Added the device name and the current volume number |
38 | as arguments to the end of tape script (dump -F option). | |
39 | ||
24ea1fb9 SP |
40 | 6. Made the multi-volume dump work again (after having |
41 | broken it in 0.4b15). | |
42 | ||
2f7e72ce SP |
43 | Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) |
44 | =================================================================== | |
d3393043 SP |
45 | |
46 | 1. Added a prompt command in interactive restore mode. Thanks | |
47 | to Andreas Dilger <adilger@home.com> for the patch. | |
d6f78b13 | 48 | |
92a9bf12 SP |
49 | 2. Fixed a buffer overflow problem in dump (caused by |
50 | not checking the size of the filesystem parameter). | |
51 | Thanks to Kim Yong-jun <loveyou@hackerslab.org> for | |
52 | reporting this on Bugtraq (and to several dump users | |
53 | who forwarded me his mail). | |
54 | ||
0d7af9c5 SP |
55 | 3. Added the '-F script' option to dump in order to |
56 | launch a script at the end of each tape (to be used | |
57 | with a tape changer, or to notify the sysadmin by | |
58 | pager etc.). | |
59 | ||
60 | 4. Fixed a bug in restore compare code caused by the changes | |
61 | I made in 0.4b14. | |
62 | ||
63 | 5. Fixed the treatment of options using the old BSD syntax | |
64 | in both dump and restore. | |
65 | ||
688653ea SP |
66 | Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) |
67 | ======================================================================= | |
d6f78b13 SP |
68 | |
69 | 1. Fixed a bug in dump which may have caused invalid deleted | |
70 | directories to be dumped out if they were deleted after the | |
71 | mapping pass. This could occure on active filesystem and lead | |
72 | to heap corruption (causing dump malfunction in many possible ways). | |
73 | Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this | |
74 | bug and submitting the patch. | |
ae58c8da | 75 | |
a2c9bd28 SP |
76 | 2. Fixed the handling of the filesystem parameter in dump. A |
77 | '/mnt/disk' parameter caused the disk contents to be dumped, | |
78 | but a '/mnt/disk/' parameter caused the mountpoint directory | |
79 | to be dumped (generally an empty directory). | |
80 | ||
81 | 3. Improved the output of dump in order to tell which directory | |
82 | it is currently dumping (when dumping a subtree). | |
83 | ||
20c345aa SP |
84 | 4. Added the '-e' exclude inode option to dump. Thanks to |
85 | Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch. | |
86 | ||
d8476fa5 SP |
87 | 5. Added a REPORTING-BUGS file in order to provide a guide |
88 | on how to correctly report a bug in dump/restore. | |
89 | ||
c60338a5 SP |
90 | 6. Fixed a restore problem when restoring a hard link to an inode |
91 | having the immutable or append-only attribute set. Thanks to | |
92 | Ambrose Li <acli@mingpaoxpress.com> for submitting the patch. | |
93 | ||
8eb05297 SP |
94 | 7. Fixed a compatibility problem between dumps made on little |
95 | endian machines (the format was correct) and big endian | |
96 | machines (the format was incorrect). This fix break the | |
97 | compatibility with the older dumps made on big endian | |
98 | machines (sparc, m86k, ppc etc). For the first time in | |
99 | linux dump's history (I believe), the dumps made by *BSD, | |
100 | Linux/alpha, Linux/sparc and Linux/x86 are compatible, | |
101 | so interchangeable. Thanks to Rob Cermak | |
102 | <cermak@ahab.rutgers.edu> for submitting the bug and | |
103 | helping me test the fix. | |
104 | ||
105 | 8. Fixed the way dump reports the remaining percent/time, if | |
106 | the number of blocks actually dumped exceeds the estimated | |
107 | number of blocks. Thanks to Jean-Paul van der Jagt | |
108 | <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug. | |
109 | ||
d4b74b5c SP |
110 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) |
111 | ====================================================================== | |
2f9a0c5c SP |
112 | |
113 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
114 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
115 | ||
6dda05e4 SP |
116 | 2. Removed the requirement to build the RPM as root from the |
117 | spec file. Thanks to Christian Weisgerber | |
118 | <naddy@mips.rhein-neckar.de> for submitting this. | |
119 | ||
8d957ae7 | 120 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, |
f346e363 SP |
121 | causing dump to block when dumping really huge filesystems. |
122 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
123 | helping me find this bug. | |
124 | ||
8d957ae7 | 125 | 4. Fixed the treatment for an interrupt signal when dump access |
b80c25f8 SP |
126 | the remote tape through RSH. Thanks to Christian Weisgerber |
127 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
128 | ||
8d957ae7 SP |
129 | 5. Fixed a bug which was causing dump/restore to display |
130 | garbage characters instead of the remote host name. | |
131 | ||
2f9a0c5c | 132 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) |
df172bbb | 133 | ===================================================================== |
ae58c8da SP |
134 | |
135 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
136 | <kukuk@suse.de> for submitting the patch. | |
2ed89fda | 137 | |
a29c23cc SP |
138 | 2. Fix for the exit code when using the size estimate option of |
139 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
140 | submitting the patch. | |
141 | ||
2e682895 SP |
142 | 3. Handle EINTR in atomical reads/writes in dump, which was causing |
143 | dump to fail on some systems. Thanks to Eric Jergensen | |
144 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
145 | ||
146 | 4. Handle more than 16 characters for the device names in dumpdates. | |
147 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
148 | tracking down the problem and proposing the solution. | |
149 | ||
150 | 5. Fixed a bug in dump which prevented the creation of the | |
151 | dumpdates file when doing a 0-level dump without already | |
152 | having a dumpdates file. Thanks to Patrik Schindler | |
153 | <poc@pocnet.net> for reporting the bug. | |
154 | ||
155 | 6. Changed the way dump 'S' flag reports the size estimate | |
156 | from number of blocks into bytes (making it compatible | |
157 | with the Solaris version, and simplifying things for | |
158 | amanda users). Thanks to Jason L Tibbitts III | |
159 | <tibbs@math.uh.edu> for reporting the bug. | |
160 | ||
0d0bc326 SP |
161 | 7. Fixed a compatibility problem in linux/alpha dump tape format. |
162 | Now the linux/alpha dump are (again) compatible with the | |
163 | other dump formats. But this breaks compatibility with | |
164 | older dumps made on alpha. Thanks to Mike Tibor | |
165 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
166 | ||
cf9aab8e | 167 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) |
2ed89fda SP |
168 | ====================================================================== |
169 | ||
170 | 1. Added a '--enable-kerberos' to configure. | |
5c1faba5 | 171 | |
144a6db1 | 172 | 2. Added a 'S' option to dump which determines the amount of space |
5c729713 | 173 | that is needed to perform the dump without actually doing it, similar |
144a6db1 SP |
174 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak |
175 | <cermak@ahab.rutgers.edu>. | |
176 | ||
677ee424 SP |
177 | 3. Added a 'M' multi-volume option to dump and restore which enables |
178 | dumping to multiple files (useful when dumping to an ext2 | |
179 | partition to make several dump files in order to bypass the 2GB | |
180 | file size limitation). The 'f' argument is treated as a prefix and | |
181 | the output files will be named <prefix>001, <prefix>002 etc. With | |
182 | the 'M' flag, restore automatically selects the right file without | |
183 | asking to enter a new tape each time. | |
184 | ||
7fbb9b02 | 185 | 4. Fixed a memory leak which was causing dump to grow very big |
a29c23cc SP |
186 | (270MB when dumping a 10GB filesystem...). Thanks to Jason |
187 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
7fbb9b02 | 188 | |
27026010 SP |
189 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) |
190 | ====================================================================== | |
5c1faba5 SP |
191 | |
192 | 1. Make configure test if the system glob routines support | |
193 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
a95c4c36 SP |
194 | routines instead of system ones. Thanks to Bernhard Sadlowski |
195 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
196 | and helping me resolve this and other minor libc5 compiling | |
197 | glitches. | |
08ebf8d7 | 198 | |
c5886bd7 SP |
199 | 2. Fix a problem when dumping a ext2fs with the 'filetype' |
200 | feature enabled. Thanks to Patrick J. LoPresti | |
201 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
202 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
203 | ||
4267a8ad SP |
204 | 3. Made the nodump flag work on directories. A directory which |
205 | has the nodump flag gets never dumped, regardless of its | |
206 | contents. | |
207 | ||
c930abff SP |
208 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> |
209 | which allows dump on an active ext3 filesystem. However, this | |
210 | is a "quick and dirty" patch which enables backup of an ext3 | |
211 | filesystem through the ext2 compatibility (by ignoring the | |
212 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
213 | it is dumped (it should not). | |
214 | ||
215 | 5. Test the superblock compatibility flags when dumping, in order | |
216 | to be sure that we know how to deal with specific features. | |
217 | ||
08ebf8d7 SP |
218 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) |
219 | ==================================================================== | |
220 | ||
221 | 1. Use lchown instead of chown, fixing a possible security problem | |
222 | when restoring symlinks (a malicious user could use this | |
223 | to deliberately corrupt the ownership of important system files). | |
224 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
225 | this and providing the patch. | |
ec387a12 | 226 | |
c154548c SP |
227 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) |
228 | ==================================================================== | |
ec387a12 | 229 | |
df9ae507 SP |
230 | 1. Put dump sources under CVS, added Id tags in all files so |
231 | one can use 'ident' on binary files. | |
232 | ||
233 | 2. Added the dump/restore version in the usage text so one can | |
234 | easily verify the version he is using. | |
ec387a12 | 235 | |
3072400e SP |
236 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes |
237 | a va_start/va_end problem on linux-ppc (always call va_start | |
238 | va_end in pairs each time we use a vararg function). | |
239 | ||
fa58b58d SP |
240 | 4. Added again the DT_* constants because old libc does not |
241 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
242 | for submitting the bug report. | |
243 | ||
f34aca37 SP |
244 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs |
245 | this should enable dumping big (huge) filesystems. | |
246 | ||
247 | 6. Added the RSH environment variable in order to be able to | |
0c62667d SP |
248 | use a rsh replacement like ssh when doing remote backups (and |
249 | bypass the security limitations of rcmd). Now you can do remote | |
250 | backups without being root (or making dump setuid root). | |
251 | ||
f34aca37 | 252 | 7. Modified again the way dumpdates works. For incremental dumps, |
60f5ede9 SP |
253 | we need to read dumpdates even if we are not using 'u' option. |
254 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
255 | this should work. | |
256 | ||
8d4197bb SP |
257 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) |
258 | =================================================================== | |
259 | ||
260 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
261 | was not compiled in. | |
262 | ||
263 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
264 | to them (fsetflags takes a char*, setflags an open fd!). | |
265 | ||
266 | 3. (f)setflags is called only if the flags aren't empty. If the | |
267 | file is a special file, a warning is printed, because changing | |
268 | flags implies opening the device. Normally, a special file | |
269 | should not have any flag... (Debian bug #29775, patch provided | |
270 | by Abhijit Dasgupta <abhijit@ans.net>). | |
271 | ||
272 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
273 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
274 | ||
275 | 5. Changed the default behaviour to not create dumpdates | |
276 | unless 'u' option is specified. Removed the old "debian-patch" | |
277 | which provided the same thing. (Debian bug #38136, #33818). | |
278 | ||
279 | 6. Removed all those dump*announce, since they were getting old... | |
280 | ||
281 | 7. Added warning messages if dumpdates does not exist and | |
282 | when an inferior level dump does not exist (except for a level 0 | |
283 | dump). | |
284 | ||
285 | 8. Debugged the glob calls in interactive mode: restore used a | |
286 | dirent struct which was different from the /usr/include/dirent.h | |
287 | one (this used to work, is it a glibc2 change?), so none of the | |
288 | compat glob (which used /usr/include/dirent.h) or the system glob | |
289 | worked. Restore use now the system dirent (and the system | |
290 | DT_* constants), which are compatible with BSD ones. | |
291 | ||
292 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
293 | the location of dumpdates file. By default, it is | |
294 | /etc/dumpdates. | |
295 | ||
296 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
297 | included the current date/version in man pages. | |
298 | ||
299 | 11. Corrected the estimation of remaining time when | |
300 | the operator doesn't change the tapes quickly enough. This | |
301 | was an old bug, I thought I corrected it, and discovered | |
302 | that in fact it was corrected in two different places, so | |
303 | the results canceled each other... | |
304 | ||
305 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
306 | =================================================================== | |
ddd2ef55 SP |
307 | |
308 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
309 | ||
310 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
311 | isn't specified. | |
312 | - several fixes in the man pages. | |
313 | - update the default tape device to /dev/st0. | |
314 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
315 | - buffer overruns. | |
316 | - use environment variable for TMPDIR (instead of /tmp). | |
317 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
318 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
319 | - wire $(OPT) throughout Makefile's. | |
320 | ||
8d4197bb SP |
321 | 2. Upgrade the dump revision to 1, making possible to dump filesystems |
322 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
ddd2ef55 | 323 | |
8d4197bb SP |
324 | 3. Fix some compile warnings, prototype all functions. |
325 | ||
326 | 4. Use glibc err/glob instead of internal compatibility | |
ddd2ef55 SP |
327 | routines (only if available). |
328 | ||
8d4197bb SP |
329 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided |
330 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
331 | ||
332 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
333 | ====================================================================== | |
b45f51d6 SP |
334 | |
335 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
336 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
337 | tape length calculation" flag, dump/restore can use kerberos now | |
338 | (this is NOT tested), use environment variables for TAPE and | |
339 | RMT etc.). | |
340 | ||
341 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
342 | ||
343 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
344 | tapes (files splited accros two tapes give "size changed" errors | |
345 | when comparing). | |
346 | ||
347 | 4. Corrected the long standing bug when dumping multiple tapes. | |
348 | This works for me, needs further testing. | |
1227625a | 349 | |
8d4197bb SP |
350 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) |
351 | ==================================================================== | |
1227625a SP |
352 | |
353 | 1. Dump now runs correctly on kernels 2.1.x | |
354 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
355 | ||
356 | Changes between versions 0.4b2 and 0.4b3 | |
357 | ======================================== | |
358 | ||
359 | 1. Use realpath() if available | |
360 | ||
361 | 2. Report statistics | |
362 | ||
363 | Changes between versions 0.4b1 and 0.4b2 | |
364 | ======================================== | |
365 | ||
366 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
367 | the patch) | |
368 | ||
369 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
370 | ||
371 | 3. Fixed configure.in to correctly handle --enable-rmt | |
372 | ||
373 | Changes between versions 0.3 and 0.4b1 | |
374 | ====================================== | |
375 | ||
376 | 1. Integrated the changes from 4.4BSD-Lite2 | |
377 | ||
378 | 2. Integrated the patches from Debian and Red Hat | |
379 | ||
380 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
381 | ||
382 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
383 | should solve the endianness problem on SparcLinux. | |
384 | ||
385 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
386 | distribution's one) to use autoconf | |
387 | ||
388 | 6. Fixed a few minor bugs | |
389 | ||
390 | Changes between versions 0.2e and 0.2f | |
391 | ====================================== | |

393 | 1. Added the creation of named pipes (fifos) in restore. | |
394 | ||
395 | 2. Added the -N flag in the restore manual page. | |
396 | ||
397 | 3. Added the file kernel.patch which contains the llseek() optimization | |
398 | patch for 1.2.x kernels. | |
399 | ||
400 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
401 | not restored. | |
402 | ||
403 | 5. Integrated some changes from FreeBSD 2.2. | |
404 | ||
405 | 6. Added a call to ftruncate() after restoring each file to restore | |
406 | correctly files ending by a hole. | |
407 | ||
408 | Changes between versions 0.2d and 0.2e | |
409 | ====================================== | |
410 | ||
411 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
412 | with owner = root (0) and group = root/wheel/whatever (0). | |
413 | ||
414 | Changes between versions 0.2c and 0.2d | |
415 | ====================================== | |
416 | ||
417 | 1. Dump is now able to backup 2GB+ filesystems. | |
418 | ||
419 | 2. Dump and restore can now be linked as static binaries. | |
420 | ||
421 | Changes between versions 0.2b and 0.2c | |
422 | ====================================== | |
423 | ||
424 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
425 | ||
426 | Changes between versions 0.2a and 0.2b | |
427 | ====================================== | |
428 | ||
429 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
430 | ||
431 | 2. Enabled optimization again. | |
432 | ||
433 | Changes between versions 0.2 and 0.2a | |
434 | ===================================== | |
435 | ||
436 | 1. Disabled the optimization during compilation. | |
437 | ||
438 | Changes between versions 0.1 and 0.2 | |
439 | ==================================== | |
440 | ||
441 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
442 | the fs_type field (actually, I modified the file fstab.c to make it | |
443 | use the mntent functions). | |
444 | ||
445 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
446 | made by dump should be readable by the BSD restore and backups made | |
447 | by the BSD dump should be readable by restore. Unfortunately, this | |
448 | means that the dump format has changed between version 0.1 and version | |
449 | 0.2 :-( | |
450 | ||
451 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
452 | filesystems like the BSD version. | |
453 | ||
454 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
455 | than 2 GB. | |
456 | ||
457 | Changes between versions 0.0 and 0.1 | |
458 | ==================================== | |
459 | ||
460 | 1. Now create links rdump and rrestore during the `make install' step. | |
461 | ||
462 | 2. Linux port specific bugs added to the manual pages | |
463 | ||
464 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
465 | incremental backups. | |
466 | ||
467 | 4. Better ls-like format in restore in interactive mode. |
