Fixed the signal handling in dump (which I broke in 0.4b17) + which was causing several strange dump failures (dump + hanged or segmentation faults etc). + +2. Specified the default blocksize in the dump man page. + +3. Changed two info messages of restore to be written on stdout + instead of stderr in order to leave stderr only for errors + or warnings. Thanks to Stephen Atwell + for the suggestion. + +4. Corrected an off by one calculation which prevented + dumping a directory having a 1 character name length. + Thanks to Bernhard Erdmann + for reporting the bug. + +5. Reinforce dump in order to allow only level 0 and no + -u option when dumping a subdirectory, and document + this in the man page. Thanks to Bernhard Erdmann + for reporting the bug. + +6. Fixed a small harmless bug in restore which caused + in some conditions hard links to be restored several + times (therefore generation some warning messages). + Thanks to Kenneth Porter for + reporting the bug. + +7. Update the RPM spec file to the latest RedHat version, + providing FHS packaging and other cosmetic changes. + +Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000) +=================================================================== + +1. Fixed a potential buffer overflow in restore. Thanks + to Stan Bubrouski for reporting + the bug. + +2. Fixed a readline-related bug which prevented + 'cat DUMPFILE | restore -i -f -' from working. Thanks + to Charles Karney + for the bug report. + +3. Changed a few "panic" into "exit", causing restore to + be more stable against some attacks (like the last one + reported on Bugtraq, although the last version of restore + was not vulnerable - just dumped core). Thanks to + Andreas Hasenack for reporting + the bugs to me. + +4. Removed the suid-root bit on dump and restore in the + default build (and generated RPMs). It should be safer + now. Users who need the suid-root capabilities in order + to make network backups should read first the man page + of dump and enable the suid bit manually. + +5. Added -ltermcap to the compile parameters for restore + when using readline support, in order to make the compile + process work on some systems (SuSE ?). Thanks to + Patrik Schindler for reporting the bug. + +Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) +==================================================================== + +1. The -F script is called now *only* at the end of a tape, + not at the end of the dump. Thanks to Christian Haul + for the bug report. + + Normally, the device name and the current volume number + are passed on the command line of the script. However, + if you want the old style script (with no arguments + passed on the command line), you can enable it in + configure with the --enable-oldstylefscript. + +2. Use posix signal handling to preserve dump functionality + with libc5. Thanks to Jeff Johnson for + the patch. + +3. Made the exit code of restore in case of a 'C'ompare + command reflect the result of the compare. An exit status + of 0 means the dump archive is correct, 1 means tape errors, + 2 means that some files were modified. Thanks to Kenneth Porter + for the suggestion. + +4. Made (finally) quotes work in interactive restore. + +5. Small fixes in order to allow dump to compile with a + really old e2fsprogs version. Thanks to Ian Zimmerman + for the bug report. + +6. Add GNU readline capabilities to interactive restore. + Use configure's --enable-readline flag to enable this feature. + Thanks to Patrik Schindler for the + suggestion. + +7. Do the compare on the fly in restore 'C' mode (this will + allow not to exhaust the available /tmp space when + ccmparing large files). Thanks to Kenneth Porter + for the suggestion. + +Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) +==================================================================== + +1. Fixed some several duplicate 'DUMP: DUMP:' in the + output of dump. + +2. Corrected the estimation of blocks to dump. Note that + this is still wrong for large directory inodes, due + to the size of a BSD directory entry on the tape + (estimation is based on the size of the ext2 directory, + which is smaller because it doesn't contain the null + character at the end). + +3. Made dump report the total number of MB written to + tape at the end of run. Thanks to W. Reilly Cooley + for the patch. + +4. Added the -X option to restore giving the possibility + to read the names of the files to be extracted/listed + from a text file (in addition of the command line). + Thanks to Dejan Muhamedagic for the + patch. + +5. Added the device name and the current volume number + as arguments to the end of tape script (dump -F option). + +6. Made the multi-volume dump work again (after having + broken it in 0.4b15). + +Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) +=================================================================== + +1. Added a prompt command in interactive restore mode. Thanks + to Andreas Dilger for the patch. + +2. Fixed a buffer overflow problem in dump (caused by + not checking the size of the filesystem parameter). + Thanks to Kim Yong-jun for + reporting this on Bugtraq (and to several dump users + who forwarded me his mail). + +3. Added the '-F script' option to dump in order to + launch a script at the end of each tape (to be used + with a tape changer, or to notify the sysadmin by + pager etc.). + +4. Fixed a bug in restore compare code caused by the changes + I made in 0.4b14. + +5. Fixed the treatment of options using the old BSD syntax + in both dump and restore. + +Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) +======================================================================= + +1. Fixed a bug in dump which may have caused invalid deleted + directories to be dumped out if they were deleted after the + mapping pass. This could occure on active filesystem and lead + to heap corruption (causing dump malfunction in many possible ways). + Thanks to Jan Sanislo for finding this + bug and submitting the patch. + +2. Fixed the handling of the filesystem parameter in dump. A + '/mnt/disk' parameter caused the disk contents to be dumped, + but a '/mnt/disk/' parameter caused the mountpoint directory + to be dumped (generally an empty directory). + +3. Improved the output of dump in order to tell which directory + it is currently dumping (when dumping a subtree). + +4. Added the '-e' exclude inode option to dump. Thanks to + Isaac Chuang for contributing with the patch. + +5. Added a REPORTING-BUGS file in order to provide a guide + on how to correctly report a bug in dump/restore. + +6. Fixed a restore problem when restoring a hard link to an inode + having the immutable or append-only attribute set. Thanks to + Ambrose Li for submitting the patch. + +7. Fixed a compatibility problem between dumps made on little + endian machines (the format was correct) and big endian + machines (the format was incorrect). This fix break the + compatibility with the older dumps made on big endian + machines (sparc, m86k, ppc etc). For the first time in + linux dump's history (I believe), the dumps made by *BSD, + Linux/alpha, Linux/sparc and Linux/x86 are compatible, + so interchangeable. Thanks to Rob Cermak + for submitting the bug and + helping me test the fix. + +8. Fixed the way dump reports the remaining percent/time, if + the number of blocks actually dumped exceeds the estimated + number of blocks. Thanks to Jean-Paul van der Jagt + for reporting the bug. + +Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) +====================================================================== + +1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski + for reporting the bug. + +2. Removed the requirement to build the RPM as root from the + spec file. Thanks to Christian Weisgerber + for submitting this. + +3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, + causing dump to block when dumping really huge filesystems. + Many thanks to Patrik Schindler for + helping me find this bug. + +4. Fixed the treatment for an interrupt signal when dump access + the remote tape through RSH. Thanks to Christian Weisgerber + for providing the patch. + +5. Fixed a bug which was causing dump/restore to display + garbage characters instead of the remote host name. + +Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) +===================================================================== + +1. Small fix in the dump man page. Thanks to Thorsten Kukuk + for submitting the patch. + +2. Fix for the exit code when using the size estimate option of + dump. Thanks to Matti Taskinen for + submitting the patch. + +3. Handle EINTR in atomical reads/writes in dump, which was causing + dump to fail on some systems. Thanks to Eric Jergensen + for reporting the bug and submitting the patch. + +4. Handle more than 16 characters for the device names in dumpdates. + (up to 255 now). Thanks to Rainer Clasen for + tracking down the problem and proposing the solution. + +5. Fixed a bug in dump which prevented the creation of the + dumpdates file when doing a 0-level dump without already + having a dumpdates file. Thanks to Patrik Schindler + for reporting the bug. + +6. Changed the way dump 'S' flag reports the size estimate + from number of blocks into bytes (making it compatible + with the Solaris version, and simplifying things for + amanda users). Thanks to Jason L Tibbitts III + for reporting the bug. + +7. Fixed a compatibility problem in linux/alpha dump tape format. + Now the linux/alpha dump are (again) compatible with the + other dump formats. But this breaks compatibility with + older dumps made on alpha. Thanks to Mike Tibor + for helping me in finding this bug. + +Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) +====================================================================== + +1. Added a '--enable-kerberos' to configure. + +2. Added a 'S' option to dump which determines the amount of space + that is needed to perform the dump without actually doing it, similar + to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak + . + +3. Added a 'M' multi-volume option to dump and restore which enables + dumping to multiple files (useful when dumping to an ext2 + partition to make several dump files in order to bypass the 2GB + file size limitation). The 'f' argument is treated as a prefix and + the output files will be named 001, 002 etc. With + the 'M' flag, restore automatically selects the right file without + asking to enter a new tape each time. + +4. Fixed a memory leak which was causing dump to grow very big + (270MB when dumping a 10GB filesystem...). Thanks to Jason + Fearon for reporting the bug. + +Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) +====================================================================== + +1. Make configure test if the system glob routines support + extended syntax (ALTDIRFUNC). If not, use the internal glob + routines instead of system ones. Thanks to Bernhard Sadlowski + for reporting the bug + and helping me resolve this and other minor libc5 compiling + glitches. + +2. Fix a problem when dumping a ext2fs with the 'filetype' + feature enabled. Thanks to Patrick J. LoPresti + for reporting the bug and to + Theodore Y. Ts'o for providing the patch. + +3. Made the nodump flag work on directories. A directory which + has the nodump flag gets never dumped, regardless of its + contents. + +4. Integrate a patch from Jeremy Fitzhardinge + which allows dump on an active ext3 filesystem. However, this + is a "quick and dirty" patch which enables backup of an ext3 + filesystem through the ext2 compatibility (by ignoring the + NEEDS_RECOVERY bit). The journal file is not recognized and + it is dumped (it should not). + +5. Test the superblock compatibility flags when dumping, in order + to be sure that we know how to deal with specific features. + +Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) +==================================================================== + +1. Use lchown instead of chown, fixing a possible security problem + when restoring symlinks (a malicious user could use this + to deliberately corrupt the ownership of important system files). + Thanks to Chris Siebenmann for detecting + this and providing the patch. + +Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) +==================================================================== + 1.

Added the RSH environment variable in order to be able to use a rsh replacement like ssh when doing remote backups (and bypass the security limitations of rcmd). Now you can do remote backups without being root (or making dump setuid root). +7. Modified again the way dumpdates works.
