sys/i386/conf LINT
sys/netinet ip_input.c
Log:
Add support for stealth forwarding (forwarding packets without touching
their ttl). This can be used - in combination with the proper ipfw
incantations - to make a firewall or router invisible to traceroute
and other exploration tools.
This behaviour is controlled by a sysctl variable (net.inet.ip.stealth)
and hidden behind a kernel option (IPSTEALTH).
