Hello!
Really micro patch :-) fixing odd behavior (well, in fact, I deem an
error) of FreeBSD' ip_icmp.c. You might observe this bug doing
traceroute while standing behind a GW's interface with several
IP-addresses (aliases). In this case you always got ICMP.TIMXCEED
(time exceeded) coming from IP-address which is the first on the
interface, even if your box is not using this IP-address as its
next-hop. Despite of the code selecting right IP-address for this
purpose is working well it's being confused by wrong argument it is
being given. This patch
http://www.morning.ru/~poige/patchzone/ip_icmp.c.diff
fixes namely this problem.
P.S. It seems the same problem belongs to OpenBSD and, may be, for all
*BSD derivatives.
P.P.S. the PR is already sent, now waiting...
