I have a high-level comment - python-dev is normally the wrong place for patches; please submit them to sf.net/projects/python instead.

OK, I'll post it here.

Apart from that, the patch looks fine.

Fine!

I'm not sure what you mean by "implemented": these functions are implemented by the operating system, not in the socketmodule. If you ask "why are they not exposed to Python yet?": There has been no need to do so, so far. What do I get with recvmsg that I cannot get with recv/recvfrom just as well?

You can have access to ancillary messages. You can, for example transmit credentials or file descriptors through unix sockets, which is very interesting for privilege separation.
