cjc 2002/02/25 00:29:21 PST Modified files: sys/netinet tcp_input.c Log: The TCP code did not do sufficient checks on whether incoming packets were destined for a broadcast IP address. All TCP packets with a broadcast destination must be ignored. The system only ignored packets that were _link-layer_ broadcasts or multicast. We need to check the IP address too since it is quite possible for a broadcast IP address to come in with a unicast link-layer address. Note that the check existed prior to CSRG revision 7.35, but was removed. This commit effectively backs out that nine-year-old change.
