Modified files:
sys/netinet tcp_input.c
Log:
Slight tweak to tcp.blackhole to add optional behaviour to
drop any segment arriving at a closed port.
tcp.blackhole=1 - only drop SYN without RST
tcp.blackhole=2 - drop everything without RST
tcp.blackhole=0 - always send RST - default behaviour
This confuses nmap -sF or -sX or -sN quite badly.
