Modified files:
sys/netinet tcp_input.c udp_usrreq.c
Log:
Add net.inet.tcp.blackhole and net.inet.udp.blackhole
sysctl knobs.
With these knobs on, refused connection attempts are dropped
without sending a RST, or Port unreachable in the UDP case.
In the TCP case, sending of RST is inhibited iff the incoming
segment was a SYN.
Docs and rc.conf settings to follow.
