May be broken. 4Status: Fixed by Marc for 2.4.0. 5 6This adds CONFIG_IP_NF_MATCH_RPC, which supplies two modules, 7ip_conntrack_rpc_udp and ip_conntrack_rpc_tcp, which track portmapper 8requests using UDP and TCP respectively. It also adds the record_rpc 9match for iptables, which matches if the source of the packet has 10requested that port through the portmapper before, or it is a new GET 11request to the portmapper, allowing effective RPC filtering. 12
