IP_FREEBIND is one of my favourite sockopts ;-) , as it allows race-free listening on any socket without requiring the network interface to be up. Would be cool to document this in inet(7).

--- Comment #1 from Lennart Poettering <[email protected]> 2010-10-11 14:16:07 --- Oh, and there are actually a few more undocumented IP-related sockopts defined
in /usr/include/linux/in.h that could use some documentation love.

IP_FREEBINDis one of my favourite sockopts ;-) , as it allows race-free listening on any socket without requiring the network interface to be up. Would be cool to document this in inet(7).
How does the following look?
+.TP
+.BR IP_FREEBIND " (since Linux 2.4)"
+.\" Precisely: 2.4.0-test10
+If enabled, this boolean option allows binding to an IP address +that is nonlocal or does not (yet) exist.
+This permits listening on a socket,
+without requiring the underlying network interface or the +specified dynamic IP address to be up at the time that +the application is trying to bind to it.
+This option is the per-socket equivalent of the
+.IR ip_nonlocal_bind
+.I /proc
+interface described below.

This sounds like one or more separate bug reports...
