  Modified files:
    sys/netinet          tcp_input.c tcp_seq.h 
  Log:
  - Tighten up the Timestamp checks to prevent a spoofed segment from
    setting ts_recent to an arbitrary value, stopping further
    communication between the two hosts.
  - If the Echoed Timestamp is greater than the current time,
    fall back to the non RFC 1323 RTT calculation.
