- ensure hostname from gethostname() is nul-terminated in all cases
- minor KNF
- use MAXHOSTNAMELEN over various other values/defines
- be safe will buffers that hold hostnames
- be safe with unlinking files (from freebsd)
- remove register
- clean up $NetBSD$'s.
- use inet_ntoa() in one place (from openbsd)
- nul terminate after a bunch of strncpy()'s
- #ifdef __STDC__ rather than #if (from freebsd)
- be safe with a bunch of string operations (from freebsd)
- use warn()/err() over home grown versions (some from freebsd)
- rename warn() to nodaemon() to remove conflict with above
- check errno from failed kill(2) against ESRCH (from freebsd)
- use getopt() rather than home grown versions (from freebsd)
- clean up a bunch of man pages (some from freebsd)
- check for hostname spoof (from freebsd)
- use POSIX wait() interfaces
- use sysconf(_SC_OPEN_MAX) in preference to NOFILE (from freebsd)
- deal with fork() failure
- index/rindex -> strchr/strrchr (some from freebsd)
- add B57600 and B115200 speeds (from freebsd)
- some KNF
- be safe with files passed in over the network (some from freebsd)
- check return value of malloc(), calloc() and strdup()
(1) incorrect check on length of data being written (fix provided by
Paul Sijben <Paul.Sijben@huygens.org>), and
(2) inadequate buffer (too small) for data being sent to remote meant
that properly-formed messages couldn't be created, so job removal
didn't work properly.
