Fixed a bug in the QFA feature which could have caused + a bad tape positionning on restore (causing extra delays in + restore). Credits go to Uwe Gohlke . + +2. Added a small note in the dump man page specifying that + there should be no white space between the option letter and + the -j or -z parameter, thanks to Kenneth Porter + +3. Made restore work with older versions of the readline library, + by checking in configure for several extended symbols. Restore + can now be compiled with a readline as old as the 2.0 release + (though it may be a good idea to upgrade it to a more recent + version...). Thanks to Andrew Donkin for + reporting the build failures. + +4. Fixed a performance problem with the QFA file creation in + dump, which made unnecessary seeks on the tape slowing down + the dump. Thanks to Andrew Donkin for + reporting this issue. + +Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002) +======================================================================= + +1. Fixed behaviour of dump when exceeding resource limits + (SIGXFSZ treatment). + +2. Added the -L flag to restore to allow the user to specify a + maximal allowed number of miscompares when using restore + with the -C option to check the backup. + +3. Detailed the manual entry for the -N option of restore. + +4. Added the -a flag to restore to make able doing unattended + restores in -i or -x mode (automatically walks through the + multiple dump volumes). + +5. Extended the QFA mode to work with local files and/or + remote tapes and files. This way, restore can know in advance + the tape number and the offset for the inodes to extract and + can minimize the extraction time by seeking directly to the + good tape/offset. + +6. Added the -A option to both dump and restore, + which makes dump to archive a dump table-of-contents in + the specified file to be used by restore to determine + whether a file is in the dump file that is being restored. + (the archive file syntax is also compatible with the + Solaris ufsdump generated one). + +7. Small fix in restore making it able to read some (broken ?) + Solaris ufsdump tapes. + +8. Fixed dump to correctly recognise the root filesystem when using + ext2 disk labels (LABEL=/). Thanks to John Yu + for reporting this bug. + +9. Added the -P option to restore to create a + Quick File Access file from an already made dump. Patch + contributed by Uwe Gohlke . + +10. Made restore compile and run on Solaris, making it a + possible replacement for the standard ufsrestore. Port was + contributed by Uwe Gohlke . + +Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002) +===================================================================== + +1. Added a set of backup scripts from Eugenio Diaz + in the examples section. It features + automatic (cron based) full and incremental dumping of + several filesystems on a separate filesystem. + +2. Fixed a off-by-one miscalculation which disabled dumping + a one letter subdirectory. Thanks to Chris Siebenmann + for reporting the bug. + +3. Fixed several restore bugs occuring when trying to + restore some missing files on the tape. Thanks to Chris + Siebenmann for reporting the bug. + +4. Fixed --with-ldopts configure argument passing, installing from + a separate object directory, makefile cleanups contributed + by . + +5. Fix a bug which could caused, in some conditions, the highest + number inode of a filesystem, to not be dumped. Many thanks + to Chris Siebenmann for helping me + chase this bug. + +Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001) +======================================================================= + +1. Added a mini howto from Patrick Walsh in the examples + directory. + +2. Minor man pages syntax corrections. Thanks to + Chris Danis for reporting the bugs. + +3. Added a script from David B. Peterson + to the examples section. It features dumping several + filesystems to a remote tape drive upon ssh. + +4. Added a patch provided by Richard Jones + which allows BRADEMAX (number of read errors tolerated by + dump) to be adjusted using the -I option. + +5. Fixed a bug which disabled doing "restore -C -f -". Thanks + to Clemens Stiglechner for the + patch. + +6. Add the -l option to restore to specify if, when doing a + remote restore, the file used to access the backup is a + regular file (the defaults being a tape drive). Restore needs + to know this information when reading a remote compressed + dump. Previously, this information was autodetected, but + the autodetection code fails (with ioctl: Inappropriate ioctl + for device) when using a non Linux remote box. Thanks to + many users and especially to Eros Albertazzi + for reporting this. + +7. Found a workaroung for the dump deadlock problem (3 childs + stuck in pause(), father in read()). The workaround seems + to work for me and several beta-testers. If it doesn't work + for you, please report back. + +8. Updated the RPM spec file (BuildPrereq, URL etc). + +Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001) +======================================================================== + +1. Fixed the permissions of a newly created QFA file by dump. + +2. Cleaned up the source of dump (the external variables + definition was a complete mess, making possible to have + objects overlap). + +3. Fixed restore to use the full tape volume path when doing + a compare (since it changes the working directory to the + filesystem being compared in the process). + +4. Added the -q option to dump which makes dump abort + whenever it needs operator attention. It should be + easier to use dump in scripts with this option. + +5. Detect the use of incompatible options to dump and + refuse them (like -a and -B options together). + +6. Added bzip2 compression to dump/restore (use option -j level + to select it). Note that you will need a restore version + >= 0.4b24 in order to restore a bzip2 compressed dump. + The same warning as for the zlib compression applies: + the tape format of a bzip2 dump is not compatible with the + original BSD tape format. + +7. Fixed a overflow problem in dump corrupting the dump when + very large files were encountered. Thanks to Vladimir Nadvornik + for the bug report. + +8. Added a ioctl(BLKFLSBUF) in dump which should flush the + kernel buffer/page cache before starting the dump, helping + a bit those who use dump on mounted filesystems. Thanks to + John Yu and to Theodore T'so + for this suggestion. + +9. Updated the RPM spec file following the RedHat changes + (dynamically linked binaries now in /usr/sbin etc). + +10. Added a patch from Helmut Jarausch + which enables restore to recognise multi volume compressed dumps + done on CD. Included his scripts for dump (which pipe the dump + output directly into cdrecord) and restore. There is now + possible to to backups to CD on the fly! + +Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001) +=================================================================== + +1. Fixed a buffer overflow in restore/tape.c. Patch provided by + Marcus Meissner (Caldera International Security Dept.). + +2. Implement the Sun rmt extended protocol. Patch submitted + by Ian Gordon . + +3. Check for the e2fsprogs header instead of + the linux kernel header. This ensures that dump always has the + latest version of this file. Patch submitted by + Andreas Dilger . + +4. Report any filesystem present in either /etc/fstab with a + positive passno or /etc/dumpdates in dump -w output. + Patch submitted by Andreas Dilger . + +5. Fixed the looping problem in dump introduced in the + previous version. + +6. Changed the -B option of dump to limit the size of + _compressed_ output per volume if compression is on. + Patch contributed by Helmut Jarausch + . Note however that, since + it is impossible to predict the size of the compressed + data before doing the compression, the -B limit is a bit + conservative. + +7. Fixed a bug in reading the operator typed file/tape path for + the next volume in restore. + +8. Implemented a "-F script" option to restore which permits the + user to specify a script which will be launched at the + beginning of each tape, useful for automatic programming of + tape changers for example. See the restore man page for the + script parameters and return codes. + +9. Small fix for the QFA routines provided by Uwe Gohlke + , and some recommendations for QFA uses in + the man pages. + +10. Fixed the multivolume restoring where making a mistake + to the 'Mount next tape' prompt caused several blocks to + be lost. + +11. Enhanced the -e option of dump to take as a parameter a + comma separated list of inode numbers. + +12. Added the -E option to dump which specify a file containing + inode numbers to exclude from the dump. + +13. Fixed the compressed multi-volume dump + restore. + +Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001) +================================================================== + +1. Made dump report the number of blocks dumped per volume. + Thanks to Kenneth Porter for the suggestion. + +2. Fix a bug in dump where waiting too much at the 'change volumes' + question caused the volume to be rewritten. Thanks to + Graham Reed for reporting the + bug and providing a patch. + +3. Added a compression option to dump, contributed by Jerry + Peters . + + WARNING: the compression works only on files/pipes and + drives supporting variable block size. + + WARNING2: tapes created using the compression feature are + incompatible with the standard dump tape format, and a + version of restore >= 0.4b22 will be needed for extraction. + +4. Fixed some compilation problems for glibc 2.2.2 and 64 bit + architectures. Thanks to Paul Slootman for + the patch and to Bdale Garbee for forwarding + it upstream. + +5. Many cleanups (CPP defines, const char warnings, check of + ext2fs COMPAT flags, time_t cleanups, added libext2 version + in dump usage text) by Andreas Dilger . + +6. Made --prefix option work in configure. All the install path + are now based on the configure parameters. + +7. Added the Quick File Access mode in dump/restore, contributed + by Uwe Gohlke . In this mode, dump stores in + a file tape position for each inode, and this file is used by + restore (if called with parameter Q and the filename) + to directly position the tape at the file restore is currently + working on. This saves hours when restoring single files from + large backups, saves the tapes and the drive's head. Use + --enable-qfa option of configure to compile in the QFA support. + +8. Added the possibility to dump several files and directories + in a single invocation of dump. Thanks to Uwe Gohlke + for implementing this option. + +9. Fixed the dumping and restoring of files with holes + (files ending with holes didn't get dumped or restored + correctly). + +10. Fixed a socket descriptor leak in dump, which leaved opened + 3 file descriptors per dump process (and there is one dump + process per tape). + +11. Fixed dump large file system support, by explicit use of + open64/lseek64/etc functions (explicit use needed because + e2fsprogs libraries don't behave well when compiled with + FILE_OFFSET_BITS=64). + +Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001) +====================================================================== + +1. Fixed some bugs in the dump -w|-W logic introduced by + the previous version. Thanks to Andreas Dilger + for his help on this one. + +2. Fixed again a compilation problem when using old e2fs + headers (filesystem label related). Thanks to many users + who reported this stupid error. + +3. Fixed a build problem on old lib5 based systems dealing with + _PATH_MNTTAB being undefined. Thanks to John Adams + for reporting the bug. + +4. Improved the error detection in restore when creating + the temporary files in TMPDIR. Now restore will corectly + report a 'no space left on device' error instead of + strange errors which could imply an archive corruption. + Thanks to Gabriel Somlo and + bgjenero for reporting the bug. + +5. Added the throughput information in dump's progression + messages. Thanks to Andreas Dilger + for the patch. + +6. Use libext2fs's inode scanning routines, which are particularly + robust when dealing with errors (especially when having some + bad blocks on the filesystem). Many thanks to Colin + for reporting the bug, investigating + the issues, finding a workaround, writing the patch and + fully testing it... (of course, if this patch will break + anything, he is to blame for :-)). + +7. Made dump and restore LFS aware. Dump can dump a filesystem + containing large files, generate a large file on output and + restore can restore them. This feature is not enabled by + default, use --enable-largefile option of configure to enable + it (you need to have a LFS aware glibc though). Thanks to + Andrea Arcangeli for submitting the patch, + and to Theodore T'so for his always + useful thoughts. + +8. Made dump ask upon a tape write error if it should rewrite + the current volume (assume this is a bad tape) or if it should + assume an end-of-tape condition (useful for tape drives which + behaves badly at the end of the tape). Thanks to Andreas + Dilger for the suggestion. + +Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000) +======================================================================= + +1. Fixed a small compilation problem due to a change + in the definintion of the struct sigaction in + glibc 2.0 / libc5. Thanks to Gunther Schlegel + for reporting the bug and to + Dave Platt for suggesting + a fix. + +2. Modified the label and uuid analysis in order to be + self-contained (independant of kernel/libc headers). This + should fix the compile with older kernel/libc headers and + will preserve the functionality. Thanks to Bernhard Erdmann + for reporting the bug. + +3. The 'exclude inode' option, if applied to a directory + inode, excludes now correctly all the leaves of this + directory. Thanks to John R. Dennison + for reporting the bug. + +4. Fixed the '-e' option to disable the possibility + to exclude the root inode (which causes the dumps to + be unreadable by restore). Prevented array overflow + when multiple -e options are used. + +5. Fixed dump to correctly interpret a filesystem argument + which is a mountpoint and it is not an absolute path + (as specified in the fstab). Thanks to Bernhard R. Erdmann + for reporting the bug. + +6. Made dump able to backup files larger than 2 GB. Note that + dump still doesn't cope with files larger than 4 GB. + +7. Restore the real uid and gid before invoking an external + RSH program (big hole when dump or restore is suid root!). + +8. Get the values for the default tape device and the location + of fstab file from the system headers. Thanks to + Andreas Dilger for the patch. + +9. Made dump -w|-W report all recognized filesystems + present in either /etc/fstab or /etc/dumpdates, and present + the list in the same order as in fstab file. Thanks + to Andreas Dilger for the patch. + +10. Made dump's -a (automatic end of tape detection) the + default. Specifying one of -B, -c, -d or -s options will + override the EOM detection. Thanks to Andreas Dilger + for the patch. + +11. Save the ext2 filesystem label into the dump volume label. + Specifying a volume label on the command line (-L option) + will override this feature. Thanks to Andreas Dilger + for the patch. + +Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000) +===================================================================== + +1. 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. Updated the RPM spec file to the latest RedHat version, + providing FHS packaging and other cosmetic changes. + You will need RPM version >= 3.0.5 in order to build the RPM. + +8. Updated the configure script to check for libtermcap + before checking for libreadline, because we need this + library in order to compile the readline support. + +9. Made dump understand the LABEL= and UUID= notation + both in /etc/fstab and on the command line. Note that + you will need the /proc filesystem in order to use + these notations. Thanks to Erik Troan + for providing the patch. + +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. Put dump sources under CVS, added Id tags in all files so + one can use 'ident' on binary files. + +2. Added the dump/restore version in the usage text so one can + easily verify the version he is using. + +3. Small patch from Nuno Oliveira which fixes + a va_start/va_end problem on linux-ppc (always call va_start + va_end in pairs each time we use a vararg function). + +4. Added again the DT_* constants because old libc does not + contain them :(. Thanks to Eric Maisonobe + for submitting the bug report. + +5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs + this should enable dumping big (huge) filesystems. + +6. 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. For incremental dumps, + we need to read dumpdates even if we are not using 'u' option. + Thanks to Bdale Garbee for his ideas on how + this should work. + +Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) +=================================================================== + +1. Removed the 'k' flag from the restore 'about' text if kerberos + was not compiled in. + +2. Prototyped (f)setflags from e2fsprogs and corrected the calls + to them (fsetflags takes a char*, setflags an open fd!). + +3. (f)setflags is called only if the flags aren't empty. If the + file is a special file, a warning is printed, because changing + flags implies opening the device. Normally, a special file + should not have any flag... (Debian bug #29775, patch provided + by Abhijit Dasgupta ). + +4. Made possible to dump a file system not mentioned in /etc/fstab. + (Debian bug #11904, patch provided by Eirik Fuller ). + +5. Changed the default behaviour to not create dumpdates + unless 'u' option is specified. Removed the old "debian-patch" + which provided the same thing. (Debian bug #38136, #33818). + +6. Removed all those dump*announce, since they were getting old... + +7. Added warning messages if dumpdates does not exist and + when an inferior level dump does not exist (except for a level 0 + dump). + +8. Debugged the glob calls in interactive mode: restore used a + dirent struct which was different from the /usr/include/dirent.h + one (this used to work, is it a glibc2 change?), so none of the + compat glob (which used /usr/include/dirent.h) or the system glob + worked. Restore use now the system dirent (and the system + DT_* constants), which are compatible with BSD ones. + +9. Added a configure flag (--with-dumpdatespath) to specify + the location of dumpdates file. By default, it is + /etc/dumpdates. + +10. Added the "AUTHOR" and "AVAILABILITY" sections and + included the current date/version in man pages. + +11. Corrected the estimation of remaining time when + the operator doesn't change the tapes quickly enough. This + was an old bug, I thought I corrected it, and discovered + that in fact it was corrected in two different places, so + the results canceled each other... + +Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) +=================================================================== + +1. Integrated multiple patches from RedHat, Debian and SuSE: + + - tweak dump/itime.c to not try to read dumpdates if the 'u' option + isn't specified. + - several fixes in the man pages. + - update the default tape device to /dev/st0. + - many updates for Linux Alpha (byte ordering, size_t etc). + - buffer overruns. + - use environment variable for TMPDIR (instead of /tmp). + - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). + - workaround egcs bug (RedHat bugs #4281 and #2989). + - wire $(OPT) throughout Makefile's. + +2. Upgrade the dump revision to 1, making possible to dump filesystems + made with e2fsprogs-1.15 or newer. Nothing seems to break... + +3. Fix some compile warnings, prototype all functions. + +4.
