650fe0907f This patch cleans up the ident stuff in inetd. The code which has
been patched so many times it was a bit of a mess. There are style,
code and man page cleanups. The following are the functional changes:

	The RFC only permits the returning of 4 possible error
	codes, make sure we only return these (PR 27636).

	Use MAXLOGNAME to determine the longest usernames.

	Add a -i flag, which returns the uid instead of the username
	(this is from a PR 25787, which also contained alot of the
	cleanups in this patch).

25beb6e957 Recently, other BSDs had faith support in inetd. Though our inetd has
it already, their syntax is not compatible with ours.  It will confuse
users.  So, we have compatibility with their syntex.

aff3c2bc06 Make dg_echo return up to the first 65536 bytes of a datagram.
The patch I used isn't quite the one Lars suggested, but the size
of the largest datagram you can recv isn't #defined anywhere, and
probably isn't even bounded for some protocols.

18d474781f Switch to using a struct xucred instead of a struct xucred when not
actually in the kernel.  This structure is a different size than
what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there.  As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).

This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size.  This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

60d229e604 Allow service alias names from /etc/services to be used when specifying
internal services in inetd.conf .

The inetd(8) manpage used to say that the official name of a service
_must_ be used, yet inetd itself was hardcoded to used a service alias for
the auth service, namely ident!

Rather than change inetd.conf and break existing configurations on next
upgrade, we now allow service aliases as well as official names. This
allows the software to work as expected and still support existing
configurations.

This should not breaking existing wrapped configurations either and the
inetd(8) manpage already states that it is the service name specified in
inetd.conf that is used for calls to hosts_access(3).

70faa23160 Clarify that the services name, as specified in inetd.conf, for an
internal service should be used as the daemon name when constructing
hosts_access(5) rules.

31aade9ad1 Add command-line option (-w), specified once to enable wrapping and
twice to enable wrapping for internal wrapping as well. If the option is
not specified wrapping is turned off so that inetd will behave exactly
as it used to before TCP Wrappers was imported.

Change etc/defaults/rc.conf so as to encourage wrapping on new systems.

Clarify the use of TCP Wrappers in the IMPLEMENTATION NOTES of the
manual page.

e9effd7443 Various fixes for inetd's TCP Wrappers support:
1) Handle forking and non-forking internal services correctly.
	   Turn on wrapping for internal services because it works now.
	2) Preserve server names for each service on HUP.
	3) Honour hosts_options(5) severity option.
	4) Add IMPLEMENTATION NOTES section to clarify TCP Wrappers
	   usage and limitations.

This change may cause previously allowed builtin services (e.g. daytime)
to be denied in existing configurations.

752388eccd There seems to be a problem (most likely when there is no hosts.allow)
with wrapping the internal services, so do not wrap them for now.
