989f348a SP |
2 | |
3 | Changes between versions 0.4b24 and 0.4b25 (released ??????????????????) | |
4 | ======================================================================== | |
5 | ||
6 | 1. Added a mini howto from Patrick Walsh in the examples | |
7 | directory. | |
3dd5ecd7 | 8 | |
b82d31dc SP |
9 | 2. Minor man pages syntax corrections. Thanks to |
10 | Chris Danis <screechco@home.com> for reporting the bugs. | |
11 | ||
12 | 3. Added a script from David B. Peterson <dave@toppledwagon.com> | |
13 | to the examples section. It features dumping several | |
14 | filesystems to a remote tape drive upon ssh. | |
15 | ||
16 | 4. Added a patch provided by Richard Jones <rich@annexia.org> | |
17 | which allows BRADEMAX (number of read errors tolerated by | |
18 | dump) to be adjusted using the -I option. | |
19 | ||
f9e97496 SP |
20 | 5. Fixed a bug which disabled doing "restore -C -f -". Thanks |
21 | to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the | |
22 | patch. | |
23 | ||
80dea635 SP |
24 | 6. Add the -l option to restore to specify if, when doing a |
25 | remote restore, the file used to access the backup is a | |
26 | regular file (the defaults being a tape drive). Restore needs | |
27 | to know this information when reading a remote compressed | |
28 | dump. Previously, this information was autodetected, but | |
29 | the autodetection code fails (with ioctl: Inappropriate ioctl | |
3195bc1f SP |
30 | for device) when using a non Linux remote box. Thanks to |
31 | many users and especially to Eros Albertazzi | |
32 | <eros@lamel.bo.cnr.it> for reporting this. | |
33 | ||
a7556ed9 SP |
34 | 7. Found a workaroung for the dump deadlock problem (3 childs |
35 | stuck in pause(), father in read()). The workaround seems | |
36 | to work for me and several beta-testers. If it doesn't work | |
37 | for you, please report back. | |
132daf88 SP |
38 | |
39 | 8. Updated the RPM spec file (BuildPrereq, URL etc). | |
40 | ||
68da8d85 SP |
41 | Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001) |
42 | ======================================================================== | |
3dd5ecd7 | 43 | |
f48a055e SP |
44 | 1. Fixed the permissions of a newly created QFA file by dump. |
45 | ||
46 | 2. Cleaned up the source of dump (the external variables | |
47 | definition was a complete mess, making possible to have | |
48 | objects overlap). | |
6d9ffa3e | 49 | |
e46507f2 SP |
50 | 3. Fixed restore to use the full tape volume path when doing |
51 | a compare (since it changes the working directory to the | |
52 | filesystem being compared in the process). | |
53 | ||
e084ba00 SP |
54 | 4. Added the -q option to dump which makes dump abort |
55 | whenever it needs operator attention. It should be | |
56 | easier to use dump in scripts with this option. | |
57 | ||
8cef350e SP |
58 | 5. Detect the use of incompatible options to dump and |
59 | refuse them (like -a and -B options together). | |
60 | ||
88ef261e SP |
61 | 6. Added bzip2 compression to dump/restore (use option -j level |
62 | to select it). Note that you will need a restore version | |
63 | >= 0.4b24 in order to restore a bzip2 compressed dump. | |
64 | The same warning as for the zlib compression applies: | |
65 | the tape format of a bzip2 dump is not compatible with the | |
66 | original BSD tape format. | |
67 | ||
1df5c692 SP |
68 | 7. Fixed a overflow problem in dump corrupting the dump when |
69 | very large files were encountered. Thanks to Vladimir Nadvornik | |
70 | for the bug report. | |
71 | ||
103245b6 SP |
72 | 8. Added a ioctl(BLKFLSBUF) in dump which should flush the |
73 | kernel buffer/page cache before starting the dump, helping | |
74 | a bit those who use dump on mounted filesystems. Thanks to | |
75 | John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu> | |
76 | for this suggestion. | |
caea5c76 SP |
77 | |
78 | 9. Updated the RPM spec file following the RedHat changes | |
79 | (dynamically linked binaries now in /usr/sbin etc). | |
80 | ||
8b7882a8 SP |
81 | 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de> |
82 | which enables restore to recognise multi volume compressed dumps | |
83 | done on CD. Included his scripts for dump (which pipe the dump | |
84 | output directly into cdrecord) and restore. There is now | |
85 | possible to to backups to CD on the fly! | |
86 | ||
3a1a7e1c SP |
87 | Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001) |
88 | =================================================================== | |
6d9ffa3e SP |
89 | |
90 | 1. Fixed a buffer overflow in restore/tape.c. Patch provided by | |
91 | Marcus Meissner (Caldera International Security Dept.). | |
fa7fb417 | 92 | |
5a7167e9 SP |
93 | 2. Implement the Sun rmt extended protocol. Patch submitted |
94 | by Ian Gordon <iangordon@users.sourceforge.net>. | |
95 | ||
e4a8bde4 SP |
96 | 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of |
97 | the linux kernel header. This ensures that dump always has the | |
98 | latest version of this file. Patch submitted by | |
99 | Andreas Dilger <adilger@turbolinux.com>. | |
100 | ||
8bfad78a SP |
101 | 4. Report any filesystem present in either /etc/fstab with a |
102 | positive passno or /etc/dumpdates in dump -w output. | |
103 | Patch submitted by Andreas Dilger <adilger@turbolinux.com>. | |
104 | ||
ad922073 SP |
105 | 5. Fixed the looping problem in dump introduced in the |
106 | previous version. | |
107 | ||
e7850aac SP |
108 | 6. Changed the -B option of dump to limit the size of |
109 | _compressed_ output per volume if compression is on. | |
110 | Patch contributed by Helmut Jarausch | |
b0522d37 SP |
111 | <jarausch@igpm.rwth-aachen.de>. Note however that, since |
112 | it is impossible to predict the size of the compressed | |
113 | data before doing the compression, the -B limit is a bit | |
114 | conservative. | |
e7850aac | 115 | |
5bbb0926 SP |
116 | 7. Fixed a bug in reading the operator typed file/tape path for |
117 | the next volume in restore. | |
118 | ||
c534413c SP |
119 | 8. Implemented a "-F script" option to restore which permits the |
120 | user to specify a script which will be launched at the | |
121 | beginning of each tape, useful for automatic programming of | |
122 | tape changers for example. See the restore man page for the | |
123 | script parameters and return codes. | |
124 | ||
b8f7cbe6 SP |
125 | 9. Small fix for the QFA routines provided by Uwe Gohlke |
126 | <uwe@ugsoft.de>, and some recommendations for QFA uses in | |
127 | the man pages. | |
128 | ||
651fb4a5 SP |
129 | 10. Fixed the multivolume restoring where making a mistake |
130 | to the 'Mount next tape' prompt caused several blocks to | |
131 | be lost. | |
132 | ||
6d732772 SP |
133 | 11. Enhanced the -e option of dump to take as a parameter a |
134 | comma separated list of inode numbers. | |
135 | ||
136 | 12. Added the -E option to dump which specify a file containing | |
137 | inode numbers to exclude from the dump. | |
138 | ||
e7979078 SP |
139 | 13. Fixed the compressed multi-volume dump + restore. |
140 | ||
9081ea90 SP |
141 | Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001) |
142 | ================================================================== | |
fa7fb417 | 143 | |
90aa4874 | 144 | 1. Made dump report the number of blocks dumped per volume. |
fa7fb417 | 145 | Thanks to Kenneth Porter <shiva@well.com> for the suggestion. |
58d85348 | 146 | |
90aa4874 SP |
147 | 2. Fix a bug in dump where waiting too much at the 'change volumes' |
148 | question caused the volume to be rewritten. Thanks to | |
149 | Graham Reed <greed@users.sourceforge.net> for reporting the | |
150 | bug and providing a patch. | |
151 | ||
a01aa5e8 | 152 | 3. Added a compression option to dump, contributed by Jerry |
401a4d13 | 153 | Peters <gapeters@worldnet.att.net>. |
a01aa5e8 | 154 | |
2b747532 SP |
155 | WARNING: the compression works only on files/pipes and |
156 | drives supporting variable block size. | |
a01aa5e8 SP |
157 | |
158 | WARNING2: tapes created using the compression feature are | |
159 | incompatible with the standard dump tape format, and a | |
160 | version of restore >= 0.4b22 will be needed for extraction. | |
161 | ||
401a4d13 SP |
162 | 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit |
163 | architectures. Thanks to Paul Slootman <paul@debian.org> for | |
164 | the patch and to Bdale Garbee <bdale@gag.com> for forwarding | |
165 | it upstream. | |
166 | ||
43460f04 | 167 | 5. Many cleanups (CPP defines, const char warnings, check of |
43ef843b SP |
168 | ext2fs COMPAT flags, time_t cleanups, added libext2 version |
169 | in dump usage text) by Andreas Dilger <adilger@turbolinux.com>. | |
43460f04 | 170 | |
60d46c35 SP |
171 | 6. Made --prefix option work in configure. All the install path |
172 | are now based on the configure parameters. | |
173 | ||
35b24fb7 SP |
174 | 7. Added the Quick File Access mode in dump/restore, contributed |
175 | by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in | |
176 | a file tape position for each inode, and this file is used by | |
177 | restore (if called with parameter Q and the filename) | |
178 | to directly position the tape at the file restore is currently | |
179 | working on. This saves hours when restoring single files from | |
180 | large backups, saves the tapes and the drive's head. Use | |
181 | --enable-qfa option of configure to compile in the QFA support. | |
182 | ||
a94ecd11 SP |
183 | 8. Added the possibility to dump several files and directories |
184 | in a single invocation of dump. Thanks to Uwe Gohlke | |
185 | <uwe@ugsoft.de> for implementing this option. | |
186 | ||
cfa03414 SP |
187 | 9. Fixed the dumping and restoring of files with holes |
188 | (files ending with holes didn't get dumped or restored | |
189 | correctly). | |
190 | ||
700b236e SP |
191 | 10. Fixed a socket descriptor leak in dump, which leaved opened |
192 | 3 file descriptors per dump process (and there is one dump | |
193 | process per tape). | |
194 | ||
95c74f38 SP |
195 | 11. Fixed dump large file system support, by explicit use of |
196 | open64/lseek64/etc functions (explicit use needed because | |
197 | e2fsprogs libraries don't behave well when compiled with | |
198 | FILE_OFFSET_BITS=64). | |
199 | ||
35e850a4 SP |
200 | Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001) |
201 | ====================================================================== | |
58d85348 SP |
202 | |
203 | 1. Fixed some bugs in the dump -w|-W logic introduced by | |
204 | the previous version. Thanks to Andreas Dilger | |
205 | <adilger@turbolinux.com> for his help on this one. | |
1099d48c | 206 | |
a23c5022 SP |
207 | 2. Fixed again a compilation problem when using old e2fs |
208 | headers (filesystem label related). Thanks to many users | |
209 | who reported this stupid error. | |
210 | ||
a1158276 | 211 | 3. Fixed a build problem on old lib5 based systems dealing with |
f1266a2f SP |
212 | _PATH_MNTTAB being undefined. Thanks to John Adams |
213 | <johna@onevista.com> for reporting the bug. | |
a1158276 | 214 | |
42bcc624 SP |
215 | 4. Improved the error detection in restore when creating |
216 | the temporary files in TMPDIR. Now restore will corectly | |
217 | report a 'no space left on device' error instead of | |
218 | strange errors which could imply an archive corruption. | |
219 | Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and | |
220 | bgjenero <bgjenero@sympatico.ca> for reporting the bug. | |
221 | ||
88f15c1b SP |
222 | 5. Added the throughput information in dump's progression |
223 | messages. Thanks to Andreas Dilger <adilger@turbolinux.com> | |
224 | for the patch. | |
225 | ||
0bd5aa90 SP |
226 | 6. Use libext2fs's inode scanning routines, which are particularly |
227 | robust when dealing with errors (especially when having some | |
228 | bad blocks on the filesystem). Many thanks to Colin | |
229 | <colin@horizon.com> for reporting the bug, investigating | |
230 | the issues, finding a workaround, writing the patch and | |
231 | fully testing it... (of course, if this patch will break | |
232 | anything, he is to blame for :-)). | |
233 | ||
7ae7e2fd | 234 | 7. Made dump and restore LFS aware. Dump can dump a filesystem |
d6967896 SP |
235 | containing large files, generate a large file on output and |
236 | restore can restore them. This feature is not enabled by | |
237 | default, use --enable-largefile option of configure to enable | |
238 | it (you need to have a LFS aware glibc though). Thanks to | |
239 | Andrea Arcangeli <andrea@suse.de> for submitting the patch, | |
240 | and to Theodore T'so <tytso@valinux.com> for his always | |
241 | useful thoughts. | |
242 | ||
7ae7e2fd SP |
243 | 8. Made dump ask upon a tape write error if it should rewrite |
244 | the current volume (assume this is a bad tape) or if it should | |
245 | assume an end-of-tape condition (useful for tape drives which | |
246 | behaves badly at the end of the tape). Thanks to Andreas | |
247 | Dilger <adilger@turbolinux.com> for the suggestion. | |
248 | ||
e93e901d SP |
249 | Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000) |
250 | ======================================================================= | |
1099d48c | 251 | |
bd731171 SP |
252 | 1. Fixed a small compilation problem due to a change |
253 | in the definintion of the struct sigaction in | |
254 | glibc 2.0 / libc5. Thanks to Gunther Schlegel | |
255 | <schlegel@riege.de> for reporting the bug and to | |
256 | Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting | |
257 | a fix. | |
1099d48c SP |
258 | |
259 | 2. Modified the label and uuid analysis in order to be | |
260 | self-contained (independant of kernel/libc headers). This | |
261 | should fix the compile with older kernel/libc headers and | |
262 | will preserve the functionality. Thanks to Bernhard Erdmann | |
263 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
264 | ||
1cd75c4c SP |
265 | 3. The 'exclude inode' option, if applied to a directory |
266 | inode, excludes now correctly all the leaves of this | |
267 | directory. Thanks to John R. Dennison | |
268 | <gerdesas@users.sourceforge.net> for reporting the bug. | |
f1d86882 | 269 | |
aec13b2a SP |
270 | 4. Fixed the '-e' option to disable the possibility |
271 | to exclude the root inode (which causes the dumps to | |
272 | be unreadable by restore). Prevented array overflow | |
273 | when multiple -e options are used. | |
274 | ||
8c363e9a SP |
275 | 5. Fixed dump to correctly interpret a filesystem argument |
276 | which is a mountpoint and it is not an absolute path | |
277 | (as specified in the fstab). Thanks to Bernhard R. Erdmann | |
278 | <be@berdmann.de> for reporting the bug. | |
279 | ||
abc63c56 SP |
280 | 6. Made dump able to backup files larger than 2 GB. Note that |
281 | dump still doesn't cope with files larger than 4 GB. | |
282 | ||
2c168f5f SP |
283 | 7. Restore the real uid and gid before invoking an external |
284 | RSH program (big hole when dump or restore is suid root!). | |
285 | ||
6169d840 SP |
286 | 8. Get the values for the default tape device and the location |
287 | of fstab file from the system headers. Thanks to | |
288 | Andreas Dilger <adilger@turbolinux.com> for the patch. | |
289 | ||
51b01afe SP |
290 | 9. Made dump -w|-W report all recognized filesystems |
291 | present in either /etc/fstab or /etc/dumpdates, and present | |
292 | the list in the same order as in fstab file. Thanks | |
293 | to Andreas Dilger <adilger@turbolinux.com> for the patch. | |
294 | ||
4f4eee3d SP |
295 | 10. Made dump's -a (automatic end of tape detection) the |
296 | default. Specifying one of -B, -c, -d or -s options will | |
297 | override the EOM detection. Thanks to Andreas Dilger | |
298 | <adilger@turbolinux.com> for the patch. | |
299 | ||
95cd8801 SP |
300 | 11. Save the ext2 filesystem label into the dump volume label. |
301 | Specifying a volume label on the command line (-L option) | |
302 | will override this feature. Thanks to Andreas Dilger | |
303 | <adilger@turbolinux.com> for the patch. | |
304 | ||
d56b7aa4 SP |
305 | Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000) |
306 | ===================================================================== | |
f1d86882 SP |
307 | |
308 | 1. Fixed the signal handling in dump (which I broke in 0.4b17) | |
309 | which was causing several strange dump failures (dump | |
310 | hanged or segmentation faults etc). | |
ddf0df5b | 311 | |
65bceb9b SP |
312 | 2. Specified the default blocksize in the dump man page. |
313 | ||
57b19d7f SP |
314 | 3. Changed two info messages of restore to be written on stdout |
315 | instead of stderr in order to leave stderr only for errors | |
316 | or warnings. Thanks to Stephen Atwell | |
317 | <satwell@urbana.css.mot.com> for the suggestion. | |
318 | ||
4f94452b SP |
319 | 4. Corrected an off by one calculation which prevented |
320 | dumping a directory having a 1 character name length. | |
321 | Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de> | |
322 | for reporting the bug. | |
323 | ||
79e31865 SP |
324 | 5. Reinforce dump in order to allow only level 0 and no |
325 | -u option when dumping a subdirectory, and document | |
326 | this in the man page. Thanks to Bernhard Erdmann | |
327 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
328 | ||
9be511dc SP |
329 | 6. Fixed a small harmless bug in restore which caused |
330 | in some conditions hard links to be restored several | |
331 | times (therefore generation some warning messages). | |
332 | Thanks to Kenneth Porter <shiva@well.com> for | |
333 | reporting the bug. | |
334 | ||
3e815572 | 335 | 7. Updated the RPM spec file to the latest RedHat version, |
1d568d1b | 336 | providing FHS packaging and other cosmetic changes. |
1099d48c | 337 | You will need RPM version >= 3.0.5 in order to build the RPM. |
1d568d1b | 338 | |
3e815572 SP |
339 | 8. Updated the configure script to check for libtermcap |
340 | before checking for libreadline, because we need this | |
341 | library in order to compile the readline support. | |
342 | ||
8954518f SP |
343 | 9. Made dump understand the LABEL= and UUID= notation |
344 | both in /etc/fstab and on the command line. Note that | |
345 | you will need the /proc filesystem in order to use | |
346 | these notations. Thanks to Erik Troan <ewt@redhat.com> | |
347 | for providing the patch. | |
348 | ||
8cca05cc SP |
349 | Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000) |
350 | =================================================================== | |
ddf0df5b SP |
351 | |
352 | 1. Fixed a potential buffer overflow in restore. Thanks | |
353 | to Stan Bubrouski <satan@fastdial.net> for reporting | |
354 | the bug. | |
30a43325 | 355 | |
64bb207a SP |
356 | 2. Fixed a readline-related bug which prevented |
357 | 'cat DUMPFILE | restore -i -f -' from working. Thanks | |
358 | to Charles Karney <karney@users.sourceforge.net> | |
359 | for the bug report. | |
360 | ||
d572dbfd SP |
361 | 3. Changed a few "panic" into "exit", causing restore to |
362 | be more stable against some attacks (like the last one | |
363 | reported on Bugtraq, although the last version of restore | |
364 | was not vulnerable - just dumped core). Thanks to | |
365 | Andreas Hasenack <andreas@conectiva.com.br> for reporting | |
366 | the bugs to me. | |
367 | ||
882090d1 SP |
368 | 4. Removed the suid-root bit on dump and restore in the |
369 | default build (and generated RPMs). It should be safer | |
370 | now. Users who need the suid-root capabilities in order | |
371 | to make network backups should read first the man page | |
372 | of dump and enable the suid bit manually. | |
373 | ||
5e04cc92 SP |
374 | 5. Added -ltermcap to the compile parameters for restore |
375 | when using readline support, in order to make the compile | |
376 | process work on some systems (SuSE ?). Thanks to | |
377 | Patrik Schindler <poc@pocnet.net> for reporting the bug. | |
378 | ||
ac443b63 | 379 | Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) |

381 | ||
382 | 1. The -F script is called now *only* at the end of a tape, | |
49023a9d | 383 | not at the end of the dump. Thanks to Christian Haul |
30a43325 SP |
384 | <haul@informatik.tu-darmstadt.de> for the bug report. |
385 | ||
d8574d45 SP |
386 | Normally, the device name and the current volume number |
387 | are passed on the command line of the script. However, | |
388 | if you want the old style script (with no arguments | |
389 | passed on the command line), you can enable it in | |
390 | configure with the --enable-oldstylefscript. | |
391 | ||
30a43325 SP |
392 | 2. Use posix signal handling to preserve dump functionality |
393 | with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for | |
394 | the patch. | |
d65ed175 | 395 | |
3d78f5f2 SP |
396 | 3. Made the exit code of restore in case of a 'C'ompare |
397 | command reflect the result of the compare. An exit status | |
398 | of 0 means the dump archive is correct, 1 means tape errors, | |
d8574d45 SP |
399 | 2 means that some files were modified. Thanks to Kenneth Porter |
400 | <shiva@well.com> for the suggestion. | |
3d78f5f2 | 401 | |
d8574d45 | 402 | 4. Made (finally) quotes work in interactive restore. |
386d48c0 | 403 | |
a110deb5 | 404 | 5. Small fixes in order to allow dump to compile with a |
d8574d45 SP |
405 | really old e2fsprogs version. Thanks to Ian Zimmerman |
406 | <itz@speakeasy.org> for the bug report. | |
a110deb5 | 407 | |
c38e5b6a SP |
408 | 6. Add GNU readline capabilities to interactive restore. |
409 | Use configure's --enable-readline flag to enable this feature. | |
d8574d45 SP |
410 | Thanks to Patrik Schindler <poc@pocnet.net> for the |
411 | suggestion. | |
412 | ||
413 | 7. Do the compare on the fly in restore 'C' mode (this will | |
414 | allow not to exhaust the available /tmp space when | |
415 | ccmparing large files). Thanks to Kenneth Porter | |
416 | <shiva@well.com> for the suggestion. | |
c38e5b6a | 417 | |

418 | Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) |
419 | ==================================================================== | |
d65ed175 SP |
420 | |
421 | 1. Fixed some several duplicate 'DUMP: DUMP:' in the | |
422 | output of dump. | |
d3393043 | 423 | |
cbc94239 SP |
424 | 2. Corrected the estimation of blocks to dump. Note that |
425 | this is still wrong for large directory inodes, due | |
426 | to the size of a BSD directory entry on the tape | |
427 | (estimation is based on the size of the ext2 directory, | |
428 | which is smaller because it doesn't contain the null | |
429 | character at the end). | |
430 | ||
431 | 3. Made dump report the total number of MB written to | |
432 | tape at the end of run. Thanks to W. Reilly Cooley | |
433 | <wcooley@nakedape.cc> for the patch. | |
434 | ||
08db2b86 SP |
435 | 4. Added the -X option to restore giving the possibility |
436 | to read the names of the files to be extracted/listed | |
1a05d45d SP |
437 | from a text file (in addition of the command line). |
438 | Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the | |
439 | patch. | |
08db2b86 | 440 | |
365a7c7c SP |
441 | 5. Added the device name and the current volume number |
442 | as arguments to the end of tape script (dump -F option). | |
443 | ||
24ea1fb9 SP |
444 | 6. Made the multi-volume dump work again (after having |
445 | broken it in 0.4b15). | |
446 | ||
2f7e72ce SP |
447 | Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) |
448 | =================================================================== | |
d3393043 SP |
449 | |
450 | 1. Added a prompt command in interactive restore mode. Thanks | |
451 | to Andreas Dilger <adilger@home.com> for the patch. | |
d6f78b13 | 452 | |
92a9bf12 SP |
453 | 2. Fixed a buffer overflow problem in dump (caused by |
454 | not checking the size of the filesystem parameter). | |
455 | Thanks to Kim Yong-jun <loveyou@hackerslab.org> for | |
456 | reporting this on Bugtraq (and to several dump users | |
457 | who forwarded me his mail). | |
458 | ||
0d7af9c5 SP |
459 | 3. Added the '-F script' option to dump in order to |
460 | launch a script at the end of each tape (to be used | |
461 | with a tape changer, or to notify the sysadmin by | |
462 | pager etc.). | |
463 | ||
464 | 4. Fixed a bug in restore compare code caused by the changes | |
465 | I made in 0.4b14. | |
466 | ||
467 | 5. Fixed the treatment of options using the old BSD syntax | |
468 | in both dump and restore. | |
469 | ||
688653ea SP |
470 | Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) |
471 | ======================================================================= | |
d6f78b13 SP |
472 | |
473 | 1. Fixed a bug in dump which may have caused invalid deleted | |
474 | directories to be dumped out if they were deleted after the | |
475 | mapping pass. This could occure on active filesystem and lead | |
476 | to heap corruption (causing dump malfunction in many possible ways). | |
477 | Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this | |
478 | bug and submitting the patch. | |
ae58c8da | 479 | |
a2c9bd28 SP |
480 | 2. Fixed the handling of the filesystem parameter in dump. A |
481 | '/mnt/disk' parameter caused the disk contents to be dumped, | |
482 | but a '/mnt/disk/' parameter caused the mountpoint directory | |
483 | to be dumped (generally an empty directory). | |
484 | ||
485 | 3. Improved the output of dump in order to tell which directory | |
486 | it is currently dumping (when dumping a subtree). | |
487 | ||
20c345aa SP |
488 | 4. Added the '-e' exclude inode option to dump. Thanks to |
489 | Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch. | |
490 | ||
d8476fa5 SP |
491 | 5. Added a REPORTING-BUGS file in order to provide a guide |
492 | on how to correctly report a bug in dump/restore. | |
493 | ||
c60338a5 SP |
494 | 6. Fixed a restore problem when restoring a hard link to an inode |
495 | having the immutable or append-only attribute set. Thanks to | |
496 | Ambrose Li <acli@mingpaoxpress.com> for submitting the patch. | |
497 | ||
8eb05297 SP |
498 | 7. Fixed a compatibility problem between dumps made on little |
499 | endian machines (the format was correct) and big endian | |
500 | machines (the format was incorrect). This fix break the | |
501 | compatibility with the older dumps made on big endian | |
502 | machines (sparc, m86k, ppc etc). For the first time in | |
503 | linux dump's history (I believe), the dumps made by *BSD, | |
504 | Linux/alpha, Linux/sparc and Linux/x86 are compatible, | |
505 | so interchangeable. Thanks to Rob Cermak | |
506 | <cermak@ahab.rutgers.edu> for submitting the bug and | |
507 | helping me test the fix. | |
508 | ||
509 | 8. Fixed the way dump reports the remaining percent/time, if | |
510 | the number of blocks actually dumped exceeds the estimated | |
511 | number of blocks. Thanks to Jean-Paul van der Jagt | |
512 | <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug. | |
513 | ||
d4b74b5c SP |
514 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) |
515 | ====================================================================== | |
2f9a0c5c SP |
516 | |
517 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
518 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
519 | ||
6dda05e4 SP |
520 | 2. Removed the requirement to build the RPM as root from the |
521 | spec file. Thanks to Christian Weisgerber | |
522 | <naddy@mips.rhein-neckar.de> for submitting this. | |
523 | ||
8d957ae7 | 524 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, |
f346e363 SP |
525 | causing dump to block when dumping really huge filesystems. |
526 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
527 | helping me find this bug. | |
528 | ||
8d957ae7 | 529 | 4. Fixed the treatment for an interrupt signal when dump access |
b80c25f8 SP |
530 | the remote tape through RSH. Thanks to Christian Weisgerber |
531 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
532 | ||
8d957ae7 SP |
533 | 5. Fixed a bug which was causing dump/restore to display |
534 | garbage characters instead of the remote host name. | |
535 | ||
2f9a0c5c | 536 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) |
df172bbb | 537 | ===================================================================== |
ae58c8da SP |
538 | |
539 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
540 | <kukuk@suse.de> for submitting the patch. | |
2ed89fda | 541 | |
a29c23cc SP |
542 | 2. Fix for the exit code when using the size estimate option of |
543 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
544 | submitting the patch. | |
545 | ||
2e682895 SP |
546 | 3. Handle EINTR in atomical reads/writes in dump, which was causing |
547 | dump to fail on some systems. Thanks to Eric Jergensen | |
548 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
549 | ||
550 | 4. Handle more than 16 characters for the device names in dumpdates. | |
551 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
552 | tracking down the problem and proposing the solution. | |
553 | ||
554 | 5. Fixed a bug in dump which prevented the creation of the | |
555 | dumpdates file when doing a 0-level dump without already | |
556 | having a dumpdates file. Thanks to Patrik Schindler | |
557 | <poc@pocnet.net> for reporting the bug. | |
558 | ||
559 | 6. Changed the way dump 'S' flag reports the size estimate | |
560 | from number of blocks into bytes (making it compatible | |
561 | with the Solaris version, and simplifying things for | |
562 | amanda users). Thanks to Jason L Tibbitts III | |
563 | <tibbs@math.uh.edu> for reporting the bug. | |
564 | ||
0d0bc326 SP |
565 | 7. Fixed a compatibility problem in linux/alpha dump tape format. |
566 | Now the linux/alpha dump are (again) compatible with the | |
567 | other dump formats. But this breaks compatibility with | |
568 | older dumps made on alpha. Thanks to Mike Tibor | |
569 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
570 | ||
cf9aab8e | 571 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) |
2ed89fda SP |
572 | ====================================================================== |
573 | ||
574 | 1. Added a '--enable-kerberos' to configure. | |
5c1faba5 | 575 | |
144a6db1 | 576 | 2. Added a 'S' option to dump which determines the amount of space |
5c729713 | 577 | that is needed to perform the dump without actually doing it, similar |
144a6db1 SP |
578 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak |
579 | <cermak@ahab.rutgers.edu>. | |
580 | ||
677ee424 SP |
581 | 3. Added a 'M' multi-volume option to dump and restore which enables |
582 | dumping to multiple files (useful when dumping to an ext2 | |
583 | partition to make several dump files in order to bypass the 2GB | |
584 | file size limitation). The 'f' argument is treated as a prefix and | |
585 | the output files will be named <prefix>001, <prefix>002 etc. With | |
586 | the 'M' flag, restore automatically selects the right file without | |
587 | asking to enter a new tape each time. | |
588 | ||
7fbb9b02 | 589 | 4. Fixed a memory leak which was causing dump to grow very big |
a29c23cc SP |
590 | (270MB when dumping a 10GB filesystem...). Thanks to Jason |
591 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
7fbb9b02 | 592 | |
27026010 SP |
593 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) |
594 | ====================================================================== | |
5c1faba5 SP |
595 | |
596 | 1. Make configure test if the system glob routines support | |
597 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
a95c4c36 SP |
598 | routines instead of system ones. Thanks to Bernhard Sadlowski |
599 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
600 | and helping me resolve this and other minor libc5 compiling | |
601 | glitches. | |
08ebf8d7 | 602 | |
c5886bd7 SP |
603 | 2. Fix a problem when dumping a ext2fs with the 'filetype' |
604 | feature enabled. Thanks to Patrick J. LoPresti | |
605 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
606 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
607 | ||
4267a8ad SP |
608 | 3. Made the nodump flag work on directories. A directory which |
609 | has the nodump flag gets never dumped, regardless of its | |
610 | contents. | |
611 | ||
c930abff SP |
612 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> |
613 | which allows dump on an active ext3 filesystem. However, this | |
614 | is a "quick and dirty" patch which enables backup of an ext3 | |
615 | filesystem through the ext2 compatibility (by ignoring the | |
616 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
617 | it is dumped (it should not). | |
618 | ||
619 | 5. Test the superblock compatibility flags when dumping, in order | |
620 | to be sure that we know how to deal with specific features. | |
621 | ||
08ebf8d7 SP |
622 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) |
623 | ==================================================================== | |
624 | ||
625 | 1. Use lchown instead of chown, fixing a possible security problem | |
626 | when restoring symlinks (a malicious user could use this | |
627 | to deliberately corrupt the ownership of important system files). | |
628 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
629 | this and providing the patch. | |
ec387a12 | 630 | |
c154548c SP |
631 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) |
632 | ==================================================================== | |
ec387a12 | 633 | |
df9ae507 SP |
634 | 1. Put dump sources under CVS, added Id tags in all files so |
635 | one can use 'ident' on binary files. | |
636 | ||
637 | 2. Added the dump/restore version in the usage text so one can | |
638 | easily verify the version he is using. | |
ec387a12 | 639 | |
3072400e SP |
640 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes |
641 | a va_start/va_end problem on linux-ppc (always call va_start | |
642 | va_end in pairs each time we use a vararg function). | |
643 | ||
fa58b58d SP |
644 | 4. Added again the DT_* constants because old libc does not |
645 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
646 | for submitting the bug report. | |
647 | ||
f34aca37 SP |
648 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs |
649 | this should enable dumping big (huge) filesystems. | |
650 | ||
651 | 6. Added the RSH environment variable in order to be able to | |
0c62667d SP |
652 | use a rsh replacement like ssh when doing remote backups (and |
653 | bypass the security limitations of rcmd). Now you can do remote | |
654 | backups without being root (or making dump setuid root). | |
655 | ||
f34aca37 | 656 | 7. Modified again the way dumpdates works. For incremental dumps, |
60f5ede9 SP |
657 | we need to read dumpdates even if we are not using 'u' option. |
658 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
659 | this should work. | |
660 | ||
8d4197bb SP |
661 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) |
662 | =================================================================== | |
663 | ||
664 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
665 | was not compiled in. | |
666 | ||
667 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
668 | to them (fsetflags takes a char*, setflags an open fd!). | |
669 | ||
670 | 3. (f)setflags is called only if the flags aren't empty. If the | |
671 | file is a special file, a warning is printed, because changing | |
672 | flags implies opening the device. Normally, a special file | |
673 | should not have any flag... (Debian bug #29775, patch provided | |
674 | by Abhijit Dasgupta <abhijit@ans.net>). | |
675 | ||
676 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
677 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
678 | ||
679 | 5. Changed the default behaviour to not create dumpdates | |
680 | unless 'u' option is specified. Removed the old "debian-patch" | |
681 | which provided the same thing. (Debian bug #38136, #33818). | |
682 | ||
683 | 6. Removed all those dump*announce, since they were getting old... | |
684 | ||
685 | 7. Added warning messages if dumpdates does not exist and | |
686 | when an inferior level dump does not exist (except for a level 0 | |
687 | dump). | |
688 | ||
689 | 8. Debugged the glob calls in interactive mode: restore used a | |
690 | dirent struct which was different from the /usr/include/dirent.h | |
691 | one (this used to work, is it a glibc2 change?), so none of the | |
692 | compat glob (which used /usr/include/dirent.h) or the system glob | |
693 | worked. Restore use now the system dirent (and the system | |
694 | DT_* constants), which are compatible with BSD ones. | |
695 | ||
696 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
697 | the location of dumpdates file. By default, it is | |
698 | /etc/dumpdates. | |
699 | ||
700 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
701 | included the current date/version in man pages. | |
702 | ||
703 | 11. Corrected the estimation of remaining time when | |
704 | the operator doesn't change the tapes quickly enough. This | |
705 | was an old bug, I thought I corrected it, and discovered | |
706 | that in fact it was corrected in two different places, so | |
707 | the results canceled each other... | |
708 | ||
709 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
710 | =================================================================== | |
ddd2ef55 SP |
711 | |
712 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
713 | ||
714 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
715 | isn't specified. | |
716 | - several fixes in the man pages. | |
717 | - update the default tape device to /dev/st0. | |
718 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
719 | - buffer overruns. | |
720 | - use environment variable for TMPDIR (instead of /tmp). | |
721 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
722 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
723 | - wire $(OPT) throughout Makefile's. | |
724 | ||
8d4197bb SP |
725 | 2. Upgrade the dump revision to 1, making possible to dump filesystems |
726 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
ddd2ef55 | 727 | |
8d4197bb SP |
728 | 3. Fix some compile warnings, prototype all functions. |
729 | ||
730 | 4. Use glibc err/glob instead of internal compatibility | |
ddd2ef55 SP |
731 | routines (only if available). |
732 | ||
8d4197bb SP |
733 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided |
734 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
735 | ||
736 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
737 | ====================================================================== | |
b45f51d6 SP |
738 | |
739 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
740 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
741 | tape length calculation" flag, dump/restore can use kerberos now | |
742 | (this is NOT tested), use environment variables for TAPE and | |
743 | RMT etc.). | |
744 | ||
745 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
746 | ||
747 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
748 | tapes (files splited accros two tapes give "size changed" errors | |
749 | when comparing). | |
750 | ||
751 | 4. Corrected the long standing bug when dumping multiple tapes. | |
752 | This works for me, needs further testing. | |
1227625a | 753 | |

756 | |
757 | 1. Dump now runs correctly on kernels 2.1.x | |
758 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
759 | ||
760 | Changes between versions 0.4b2 and 0.4b3 | |
761 | ======================================== | |
762 | ||
763 | 1. Use realpath() if available | |
764 | ||
765 | 2. Report statistics | |
766 | ||
767 | Changes between versions 0.4b1 and 0.4b2 | |
768 | ======================================== | |
769 | ||
770 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
771 | the patch) | |
772 | ||
773 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
774 | ||
775 | 3. Fixed configure.in to correctly handle --enable-rmt | |
776 | ||
777 | Changes between versions 0.3 and 0.4b1 | |
778 | ====================================== | |
779 | ||
780 | 1. Integrated the changes from 4.4BSD-Lite2 | |
781 | ||
782 | 2. Integrated the patches from Debian and Red Hat | |
783 | ||
784 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
785 | ||
786 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
787 | should solve the endianness problem on SparcLinux. | |
788 | ||
789 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
790 | distribution's one) to use autoconf | |
791 | ||
792 | 6. Fixed a few minor bugs | |
793 | ||
794 | Changes between versions 0.2e and 0.2f | |
795 | ====================================== | |
796 | ||
797 | 1. Added the creation of named pipes (fifos) in restore. | |
798 | ||
799 | 2. Added the -N flag in the restore manual page. | |
800 | ||
801 | 3. Added the file kernel.patch which contains the llseek() optimization | |
802 | patch for 1.2.x kernels. | |
803 | ||
804 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
805 | not restored. | |
806 | ||
807 | 5. Integrated some changes from FreeBSD 2.2. | |
808 | ||
809 | 6. Added a call to ftruncate() after restoring each file to restore | |
810 | correctly files ending by a hole. | |
811 | ||
812 | Changes between versions 0.2d and 0.2e | |
813 | ====================================== | |
814 | ||
815 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
816 | with owner = root (0) and group = root/wheel/whatever (0). | |
817 | ||
818 | Changes between versions 0.2c and 0.2d | |
819 | ====================================== | |
820 | ||
821 | 1. Dump is now able to backup 2GB+ filesystems. | |
822 | ||
823 | 2. Dump and restore can now be linked as static binaries. | |
824 | ||
825 | Changes between versions 0.2b and 0.2c | |
826 | ====================================== | |
827 | ||
828 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
829 | ||
830 | Changes between versions 0.2a and 0.2b | |
831 | ====================================== | |
832 | ||
833 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
834 | ||
835 | 2. Enabled optimization again. | |
836 | ||
837 | Changes between versions 0.2 and 0.2a | |
838 | ===================================== | |
839 | ||
840 | 1. Disabled the optimization during compilation. | |
841 | ||
842 | Changes between versions 0.1 and 0.2 | |
843 | ==================================== | |
844 | ||
845 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
846 | the fs_type field (actually, I modified the file fstab.c to make it | |
847 | use the mntent functions). | |
848 | ||
849 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
850 | made by dump should be readable by the BSD restore and backups made | |
851 | by the BSD dump should be readable by restore. Unfortunately, this | |
852 | means that the dump format has changed between version 0.1 and version | |
853 | 0.2 :-( | |
854 | ||
855 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
856 | filesystems like the BSD version. | |
857 | ||
858 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
859 | than 2 GB. | |
860 | ||
861 | Changes between versions 0.0 and 0.1 | |
862 | ==================================== | |
863 | ||
864 | 1. Now create links rdump and rrestore during the `make install' step. | |
865 | ||
866 | 2. Linux port specific bugs added to the manual pages | |
867 | ||
868 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
869 | incremental backups. | |
870 | ||
871 | 4. Better ls-like format in restore in interactive mode. |
