  Correct TCP connection stall denial-of-service vulnerabilities.
  
  MFC: rev 1.270 of tcp_input.c, rev 1.25 of tcp_seq.h by ps: When a TCP
  packets containing a timestamp is received, inadequate checking of
  sequence numbers is performed, allowing an attacker to artificially

  A TCP packets with the SYN flag set is accepted for established
  connections, allowing an attacker to overwrite certain TCP options.
