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).

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.

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.

Restore default SIGHUP, SIGCHLD and SIGALRM handlers in forked inetd
processes. This happens to work around the fact that hosts_access()
doesn't (but should) set SIG_IGN as the handler for SIGCHLD while it
handles the spawn option, but it would make sense even if that were
not true.
This does not address the leaking descriptors issue discussed on the

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).
