b3608ae18f Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

11522ca501 Check return code of setuid(), setgid(), and setgroups() in rwhod.
While they will not fail in normal circumstances, better safe than
sorry.

41477e05db Let rwhod use libulog.
I am not planning on providing a mechanism tot stat() the database files
directly. The disadvantage of this, is that rwhod will now be a little
bit more heavy than it used to be. It normally used to fstat() the file
descriptor to see whether the file had changed, but this is now
impossible to implement, meaning we have to parse the entire utmp file
each 180 seconds.

This is probably not an issue on modern 16-way servers, but if it turns
out to be a problem, we'll think of something.

170ac683f2 I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions.  e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard.  They will eventually be replaced when a real standard
comes out of committee.

4de932048c Ensure that received packets are at least as long as the rwho packet
header before trying to process them. Without this sanity check,
rwhod can attempt to byte-swap all of memory when a short packet
is received, and so dies with a SIGBUS.

While I'm here, change two other syslog messages to be more
informative: use dotted quad rather than hex notation for IP
addresses, and include the source IP in the 'bad from port' message.

414a35e60a Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

90ff799227 When looking for "group daemon" (since that's what's in mtree), make sure
we actually look for the *group* and not the user's gid.  user daemon
has traditionally been group 31 (guest).

Also clear out the groups vector so that it doesn't inherit the groups
of the invoking user (ever run rwhod by hand before?)  Unfortunately, we
can't empty the supplemental groups list because the !&@^#! egid is stored
in there! :-(
