itojun f05831c62a separate RFC2292 decls for MLD; sync w/ kame 2003-06-06 09:37:29 +00:00
itojun 7a5741651c - sync up MLD declaration with RFC3542 (s/MLD6/MLD/)
- routing header declaration with RFC3542
  (note: sizeof(ip6_rthdr0) has changed!)
  also, sync up with RFC2460 routing header definition (no "strict" source
  routing mode any more)

part of advanced API update (RFC2292 -> 3542).

itojun 6d8d0d63d8 sync with latest KAME in6_ifaddr/prefix/default router manipulation.
behavior changes:
- two iocts used by ndp(8) are now obsolete (backward compat provided).
  use sysctl path instead.
- lo0 does not get ::1 automatically.  it will get ::1 when lo0 comes up.

itojun ede265fffd move per-interface ip6/icmp6 stat to ifnet->if_afdata. sync w/kame 2002-05-29 02:58:28 +00:00
itojun f05aaf1533 have packed attribute to protocol structs. sync with kame 2001-12-21 02:52:18 +00:00
itojun 33429d0612 correct timing to increment icmp6 MIB variables. sync with kame 2001-12-07 10:10:43 +00:00
itojun 22b473e0f6 during ip6/icmp6 inbound packet processing, do not call log() nor printf() in
normal operation (/var can get filled up by flodding bogus packets).
sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages.
(#define ND6_DEBUG will turn it on by default)

improve stats in ND6 code.

lots of synchronziation with kame (including comments and cometic ones).

itojun 69622e75ab sync with latest kame.
- make icmp6.h spec conformant to 2292bis-02, regarding to router reumbering
  flag bit.
- latest rtadvd.

itojun 5eae50d991 update icmp6 too big validation. the change is necessary since pmtud is
mandatory for IPv6 (so we can't just validate by using connected pcb - we need
to allow traffic from unconnected pcb to do pmtud).
- if the traffic is validated by xx_ctlinput, allow up to "hiwat" pmtud
  route entries.
- if the traffic was not validated by xx_ctlinput, allow up to "lowat" pmtud
  route entries (there's upper limit, so bad guys cannot blow up our routing
  table).
sync with kame

XXX need to think again about default hiwat/lowat value.
XXX victim selection to help starvation case

itojun 23a03329ef verify ICMPv6 too big messages based on TCP pcbs, and/or IPsec SA.
TODO: udp6, and sendto consideration.  as pmtud is mandatory for IPv6,
it is rather important for us to support those cases.
TODO: more testing

XXX previous commit included "supported qtypes" icmp6 node query support.
sorry commit message was mistaken.

itojun 63de4c2cb9 nuke the following sysctl variables. "ppsratelimit" should work better.
need to recompile sbin/sysctl after updating /usr/include.
	net.inet.tcp.rstratelimit
	net.inet.icmp.errratelimit
	net.inet6.icmp6.errratelimit

itojun 0a1e211454 - do not use bitfield for router renumbering header.
- add protection mechanism against ND cache corruption due to bad NUD hints.
- more stats
- icmp6 pps limitation.  TOOD: should implement ppsratecheck(9).

itojun 07098cd363 better conformance to draft-ietf-ipngwg-icmp-name-lookups-05.
the old code was chimera of 03 and 05 draft.

-n by default, since IPv6 reverse lookup takes too much time.
use -H to enable reverse name lookup.

itojun 402493dee5 change member name for icmp6_filter, to be conformant to RFC2292.

itojun cdea88d700 support draft-ietf-ipngwg-icmp-name-lookups-05.txt, drop support for
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.

itojun bbe25244d0 remove some of cross-BSD portability #ifdef.
remove xxCTL_VARS, which is BSDI specific.

itojun 1450d6e643 bring in recent KAME changes (only important and stable ones, as usual).
- 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.

itojun 51219dabc9 to be more rfc2292 complient, move ip6.h and icmp6.h into netinet.
(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.
