- add protection mechanism against ND cache corruption due to bad NUD hints.
- more stats
- icmp6 pps limitation. TOOD: should implement ppsratecheck(9).
draft-ietf-ipngwg-icmp-name-lookups-04.txt.
There are certain bitfield change in 04 draft to 05 draft, which makes
04 "ping6 -a" and 05 "ping6 -a" not interoperable. sigh.
- remove net.inet6.ip6.nd6_proxyall. introduce proxy NDP code works
just like "arp -s".
- revise source address selection.
be more careful about use of yet-to-be-valid addresses as source.
- as router, transmit ICMP6_DST_UNREACH_BEYONDSCOPE against out-of-scope
packet forwarding attempt.
- path MTU discovery takes care of routing header properly.
- be more strict about mbuf chain parsing.
(netinet6/{ip6,icmp6}.h is non-standard path - these files should go away)
it was not possible to use cvsmove in this case.
when you try to look at history, chase it toward netinet6/{ip6,icmp6}.h.
