Aren't the udp_socket send_msg/recv_msg permissions sufficient for this
purpose (check is between the socket context and the remote port
context), i.e. you can say that it can only send_msg/recv_msg to
dns_port_t:udp_socket?

Likewise, in what cases is it not sufficient to use the tcp_socket
send_msg/recv_msg permissions (i.e. when do you truly need the separate
name_connect permission check that you proposed earlier)?
