    sys/netinet          tcp_input.c tcp_subr.c tcp_var.h 
  Log:
  Correct a bug introduced with reduced TCP state handling; make
  sure that the MAC label on TCP responses during TIMEWAIT is
  properly set from either the socket (if available), or the mbuf
  that it's responding to.
  
  Unfortunately, this is made somewhat difficult by the TCP code,
  as tcp_twstart() calls tcp_twrespond() after discarding the socket
  but without a reference to the mbuf that causes the "response".
  Passing both the socket and the mbuf works arounds this--eventually
  it might be good to make sure the mbuf always gets passed in in
  "response" scenarios but working through this provided to
  complicate things too much.
