Modified files: sbin/ping ping.8 ping.c share/man/man4 inet.4 ip.4 sys/netinet in.h in_pcb.h ip.h ip_input.c ip_output.c ip_var.h usr.bin/netstat inet.c Log: Implement support for RFC 3514 (The Security Flag in the IPv4 Header). (See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)

This fulfills the host requirements for userland support by way of the setsockopt() IP_EVIL_INTENT message.

There are three sysctl tunables provided to govern system behavior.

net.inet.ip.rfc3514:

Enables support for rfc3514. As this is an Informational RFC and support is not yet widespread this option is disabled by default.

net.inet.ip.hear_no_evil

If set the host will discard all received evil packets.

net.inet.ip.speak_no_evil

If set the host will discard all transmitted evil packets.

The IP statistics counter 'ips_evil' (available via 'netstat') provides information on the number of 'evil' packets recieved.

For reference, the '-E' option to 'ping' has been provided to demonstrate and test the implementation.
