Hi,
for better compliance with POSIX, bind() should return EAFNOSUPPORT
rather than EINVAL for a non-matching address family, and I think this
would also be the better coice for when addr_len is too small.
This is what the POSIX manpage says about the two error codes:
EAFNOSUPPORT
The specified address is not a valid address for the
address family of the specified socket.
EINVAL The socket is already bound to an address, and the pro-
tocol does not support binding to a new address; or the
socket has been shut down.
