is fixed, however it is a MFC candidate for -stable.
This could possibly be slightly more efficient and leave the listening
socket permanently in non-blocking mode, but I wasn't certain that I
could catch all the stream/wait (not nowait) mode implications.
flamage between our beloved messrs Hearn and Feldman. Further commits go
through me. I urge the contestants to direct their energies at cleaning
up main() in inetd.c, which has over time become a crawling horror.
I've taken time to write up comments for the ident code tonight,
so there should no longer be any confusion about the purpouse of
whatever is in there. Wow, me commenting code... who'd have thought
that would happen?

the rest of the code.
* Nestle block curlies between case statements correctly.
I've left the in-block declarations alone, since style(9) says we should
conform to the existing style within the code, and inetd already does
this. I've left the asprintf()'s in there because that's how Brian wants

that wastes stack space. I've clarified the error a bit (for if asprintf()

1. Cleanups of ident_stream. "Evil" stdio is less used.
2. The BSD Copyright was added to the top of builtins.c.
3. As suggested, a timeout is now implemented in the ident
service. It defaults to 10 seconds. If enough people want
it, I'll make it configurable.

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
same PR.

orthogonal.

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).

as it used to before TCP Wrappers was imported.
Change etc/defaults/rc.conf so as to encourage wrapping on new systems.

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

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