One possibility is that the code in icmp_input() processing the PMTU discovery-induced ICMP message could verify that the returned header in fact is associated with a connection on the host and maybe even has sane sequence numbers (for TCP segments). This would make it more difficult to just spray these packets at host and drop the MTU on routes. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
