In directory netbsd1:/var/slash-tmp/cvs-serv14385

Modified Files:
        tcp_input.c 
Log Message:
In tcp_input(), if the PCB we lookup for an incoming packet is a listen
socket:
- If we received a SYN,ACK, send an RST.
- If we received a SYN, and the connection attempt appears to come from
  itself, send an RST, since it cannot possibly be valid.
