Kristof Provost 64af73aade pf: Ensure that IP addresses match in ICMP error packets
States in pf(4) let ICMP and ICMP6 packets pass if they have a
packet in their payload that matches an exiting connection.  It was
not checked whether the outer ICMP packet has the same destination
IP as the source IP of the inner protocol packet.  Enforce that
these addresses match, to prevent ICMP packets that do not make
sense.
