c8fbd1ec9b If su(1) is run without an effective uid of 0, generate an error to
the user indicating that su is not running setuid, which may help
suggest to the user that it should be setuid, or should not be
running from a file system mounted nosuid.

dee651eb15 Introduce the PRECIOUSPROG knob in bsd.prog.mk, similar
to PRECIOUSLIB from bsd.lib.mk.  The side effect of this
is making installing the world under jail(8) possible by
using another knob, NOFSCHG.

60f4b54d8f When root tries to su to a non-existent user, pam_authenticate() will
normally succeed (because root can su to anyone), but pam_acct_mgmt()
will most likely fail, causing su to log a confusing "pam_acct_mgmt:
error in service module" message.  To avoid this, call getpwnam()
before pam_acct_mgmt().

7430623f55 Be sure to restore foreground group to parent su before parent su
exits, otherwise shell will be confused and does not set foreground
group correctly for next su command. This sounds like a bug in sh.

bcf123b3f6 It seems when su executes in a shell scripts, there is a timing race,
sometimes, su will receive a SIGTTOU when parent su tries to set child
su's process group as foreground group, and su will be stopped unexpectly,
ignoring SIGTTOU fixes the problem.

60b28daa8d PAM-related improvements:
- if operating "as them" (su -l), use pam_{open,close}_session()
 - allow PAM to override $HOME (pam_chroot needs this)
 - chdir early, because later on we may be chrooted and chdir will fail

Also use pid_t instead of int where applicable.

a75fd4bf6e Put child process in a different process group, ensure that the broadcast
signal never affects su directly, some shells changes its pgrp at running
or suspended time, so a broadcast SIGTSTP from child will mess up su's job
control.

also set the user's MAC label as part of the user credential setup
by setting setusercontext(3)'s SETMAC flag.  By default, change only

ed5fc39f22 When a user gets refused because the password is wrong, use the
older "BAD SU" syslog message that folks prefer. There is quite
a bit more tweaking that can be done with other similar messages.

This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want

4239cf1c01 WARNS=2 fixes.
The remaining problem of converting highly incompatible pointer types
is done by "laundering" the value through a union.

This solves the problem (in my own mind) of how a "const char *" _ever_
actually gets a value in a WARNS=2 world.
