lukem 49e5f15617 WARNSify, fix .Nm usage, deprecate register, getopt returns -1 not EOF 1997-10-19 23:30:38 +00:00
lukem aaa55367ba As per discussion with mrg, back out parts of previous change.
The appropriate entry in /etc/group as returned by getgrnam() is
used to determine if 'su root' may be permitted, rather than
checking if membership exists in the result of getgroups().

The following changes were made regarding the behaviour of the special
group for 'su root'
* allow for definition of SUGROUP (defaults to "wheel") to override group name.
* use getgrnam(SUGROUP) instead of getgrgid(0).
* only scan getgrnam(SUGROUP)->gr_mem when checking for group membership.
* be more specific as to why 'su root' failed

NOTE: If a user's primary group is SUGROUP, and they're not a member
of SUGROUP in /etc/group, they will not be able to su.

lukem 8d846dbbd1 * Notify of impending password or account expiry (check against
_PASSWORD_WARNDAYS from <pwd.h>). For non-root users, enforce expiry when
  it happens. From Simon Gerraty <sjg@zen.void.oz.au> in [bin/935].
* Check for group 0 in process's current group membership (as returned by
  getgroups(2)), instead of just looking at the entry for wheel in /etc/group.
  Based on code by Dan Caresone <dan@oink.geek.com.au> in [bin/792], and
  also solves [bin/2466].
* Clean up to pass -Wall

ghudson 1b6b85b894 As discussed on tech-userlevel, allow anyone to su if group wheel has
no members (if you have just "root" as a member, which is the shipped
default, then no one can su, as before).

christos 76ef973082 - Fix previous commit; shells require -c "command"
- RCSid police.

christos 17b3a275d4 Fix PR/2837: su [login [args]] had the wrong usage and did not work properly. Build the correct argument list and add -c for the shells.
Fix PR/2839: su will not build with Kerberos.

- Also:
	-Don't coredump when $TERM is not set.
	-Add prototypes, remove local old style declarations of system
	 functions.
	-Recognize shells that contain "csh" as being csh alike.
	-Don't build with SKEY unconditionally. Obey bsd.own.mk.

explicitly declaring function return values, etc. to make gcc -Wall

sef 583bdd93e4 Allow 'su foo -c command'. MAY BE BUGGY! (So sayeth Keith Bostic.)
I have noticed no problems yet, however.  Since Keith never did it
"properly" ...
