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.

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... I'll close this now; please reopen if there is still something to be fixed. |
