    sys/netinet          ip_output.c 
  Log:
  In ip_ctloutput(), check for a NULL inpcb pointer before dereferencing,
  as this can occur with TCP if protocol-layer socket options are set or
  queried after the connection has closed.  There are still races
  associated with ip_ctloutput() and connection close with TCP, corrected
  in HEAD via a more comprehensive set of changes, but this fixes the
  trivial panic reported on several occasions.
  
  This is a RELENG_6_1 and RELENG_6_0 errata branch candidate.
