  Modified files:
    sys/compat/linux     linux_socket.c 
  Log:
  Reject packets larger than IP_MAXPACKET in linux_sendto() for sockets
  with the IP_HDRINCL option set.  Without this change, a Linux process
  with access to a raw socket could cause a kernel panic.  Raw sockets
  must be created by root, and are generally not consigned to untrusted
  applications; hence, the security implications of this bug are
  minimal.  I believe this only affects 6-CURRENT on or after 2005-01-30.
