Modified Files: src/sys/netinet [netbsd-5-0]: tcp_input.c Log Message: Pull up following revision(s) (requested by is in ticket #859): sys/netinet/tcp_input.c: revision 1.296 Follow exactly the recommendation of draft-ietf-tcpm-tcpsecure-11.txt: Don't check gainst the last ack received, but the expected sequence number. This makes RST handling independent of delayed ACK. From Joanne M Mikkelson.
