Last change on this file since 1644 was 1644, checked in by Bruno Cornec, 17 years ago

Apply patch from Andree Leidenfrost, modified a bit to use bkpinfo->tmpdir instead of /tmp
or MINDI_CACHE when appropriate. Fix security issues in mondo
Thanks al ot Andree for catching all those issues.
Will not compile needs more work as bkpinfo->tmpdir isn't available everywhere
Should become a global in 3.x when only containing pointers.

198- run_program_and_log_output() now takes boolean operator to specify
199 whether it will log its activities in the event of _success_
200- changed sort -n +4 to sort -s +4 (Troff)
201- ask if user's kernel is sane; if 'no' then use FAILSAFE
202- ask user to confirm the tape/CD device name
203- if restoring (not archiving) then don't try to find CD-ROM's SCSI
204 node; try to find its /dev entry instead

206
20708/01 - 08/31
208- fixed verify bug --- CD#1 was being verified again & again & ...
209- detect boot loader + device; if not detectible then _ask_
210- if run interactively, assume tape size is irrelevant & don't ask
211 for it; Mondo should handle end-of-tape gracefully now
212- worked on handling unknowng media size
213- added interactively_obtain_media_parameters_from_user()
214- when trying to mount CD-ROM, find_and_mount_actual_cd() will
215 now call find_cdrom_device() to try to find the /dev entry first
216- fixed serious bug in zero_out_a_device()
217- cleaned up some log_it() calls
218- fixed minor bug in find_cdrom_device()
219- better at distinguishing between live filesystem and ramdisk
220
22107/24/2002
