itojun 74377e4ab2 md5/bcrypt password starts with $[12], so use ^ in regex 2002-06-18 22:43:53 +00:00

atatat bc451d0928 The check_rootdotfiles section mucks with the PATH setting, but
never puts it back properly.  As such, jobs run later that expect
there to be a path will lose badly (eg, run lintpkgsrc -i from
security.local).  Let's just re-export the PATH.

lukem 1dfde69630 Support shell metacharacters (`*', '?', '[') in /etc/changelist lines,
including checks for "backups that exist when actual file is deleted", a la
the existing mechanism used for "/etc/ifconfig.*" ... "/etc/rc.d/*" checks.
This resolves [security/15798] from Bob Kemp <bob@allegory.demon.co.uk>.

lukem 98228effd2 Use "nodiff" instead of "nomail" for the tag which is used to exclude
files from having the changes diff generated.  Suggested by Michael Graff.

lukem 74cf1ec6f4 minor optimisation suggested by christos 2001-10-14 00:42:31 +00:00
lukem 6c2d977e6f A few more changes, from more discussions with Andrew Brown.
- Resurrect /etc/changelist, even if it's an "empty" file by default,
  because it's easier to use than /etc/mtree/special.local for adding
  a couple of simple files. Back by popular demand (hi @@@! :-)
- Add /etc/rc.d/* to the list of "dynamic" files; this notices changes
  in user-added scripts
- Only calculate the mtree -I nomail list once, and re-use
- Use "cat foo | while read file" instead of "for file in `cat foo`" ;
  handles whitespace better...
2001-10-13 14:22:11 +00:00
lukem 96a1608ee4 Major overhaul, with help from Andrew Brown <atatat@netbsd.org>.
Features:
- Add a bunch of stuff to /etc/mtree/special to enable removal of
  /etc/changelist:
	- files which we want to monitor for changes but don't want to
	  see the diffs of (master.passwd, ssh_host_key, ...) are
	  tagged with "nomail"
	- files which we don't want to monitor are tagged with "exclude"
	  (such as netgroup.db, kvm.db, ...)
	- monitor /etc/mtree/special.local, /root/.ssh/*
	- remove /etc/changelist, and a bunch of XXX comments
	- use mtree(8)'s -D, -I, and -E to generate lists of files to
	  actually do the changelist stuff on.
	- support /etc/mtree/special.local as an optional user-provided
	  version of /etc/mtree/special (effectively, an enhanced
	  /etc/changelist)
- Add code to monitor: /etc/ifconfig.* /etc/raid*.conf /etc/rc.conf.d/*
  including support for these files being added and removed at will.
- If /sbin/fdisk exists, backup the output of "fdisk $disk" for all
  the active disk drives as part of $check_disklabels
- Check permissions on: ~/.ssh/* ~/.shosts

Details:
- Reorder initialisation of defaults
- Remove special case for /etc/master.passwd "monitor but don't email diffs"
  with general case for other similar files.
- Keep all `autogenerated' files (such as disklabel.*, setuid.current, ...)
  in "$backup_dir/work", to minimise name clashes.
- Add migrate_file(old, new) to do the hard work of migrating files
  from the old `top level' /var/backups mechanism to the `full path'
  mechanism recently added. Use this appropriately.
- Add backup_and_diff(file, printdiffs), to the hard work of backing-up
  and diff-ing files.
- Cleanup use of shell redirects
- /bin/sh supports ~root globbing, so use it.
- Improve umask checking; use awk regex rather than awk math

atatat 9202500182 Add a chunk of code to check the installed pkgs list by making a list
of all installed pkgs and their +CONTENTS and +REQUIRED_BY files (if
they have one) and handling this file along with all the other
CHANGELIST stuff.

Greg Woods gets points for coming up with the idea.

Luke Mewburn asked me to do it, and provided lots of criticism along
the way.

perry 247041e342 Update the password sanity checking thusly:
1) If a password entry is of the form \*[A-z-]+, do not complain that
   the account is off but has a valid password. Thus you can do
   passwords like *ssh to indicate ssh only logins.
   We should come up with a standard scheme for what various *keywords mean.
   Note that if the field length is 13, 20 or 34 you'll still get
   bitched at.
   This code should be cleaned up. (So should the password scheme.)
2) If the entry is for "toor", don't complain that the account is off
   but has a valid shell. We ship with toor:*:, there is no point in
   complaining about it.

Part of the campaign against spurious security warning output.

perry 215d097e45 run mtree on the special file using the new -l option, so it will not

atatat 6534ee3cfb When backing files listed in /etc/changelist, instead of truncating
to the basename of the file, use the whole path with $backup_dir
prepended, in effect mirrorring the directory tree.  This eliminates
the possibility of a name collision.

Closes pr bin/12727.

hubertf efc93d040b Run skeyaudit (only) from /etc/daily instead of /etc/security, else there's

abs 6258e0bf60 Add a new variable 'backup_dir', which can be used to change the backup
directory from /var/backup (useful for those of us who have a separate /var
and would like to have our backup disklabels on the root filesystem).
Default behaviour unchanged. backup_dir being unset is taken as /var/backup.
