itojun e55d3b6782 indent cleanup 2002-06-08 21:32:55 +00:00
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 ae5499819c reduce diffs with kame (mostly cosmetic).
move IPV6_CHECKSUM processing to sys/netinet6/raw_ip6.c.
constify a couple of places.

itojun 1990d680c4 do not change neighbor cache state on entry timeout,
if the cache entry is for outgoing router.

perform on-linkness check before default router (re-)seletion.

do not play with interface direct route on nd6_rtrequest.

sync a lot of cosmetic changes.  sync with kame

itojun e1196a8f6e remove unnecessary state, ND6_LLINFO_WAITDELETE, from neighbor cache
state machine.
no need for RTF_REJECT on neighbor cache entires, they are leftover from
ARP code.

itojun a1d89972c7 when chasing nd6_llinfo chain, make sure we do not touch dangling
pointer (due to RTM_DELETE during default router list management).

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 df9784d749 pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted).
have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
someone with more clue about netiso-over-ip, please help.

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 fa5c89d64a do not mistakingly forward link-local scoped packet (the bug was added
with "beyondscope" icmp6 support).
"options FAKE_LOOPBACK_IF" will honor scope on loopback outputs.  rcvif will
be real interface, not the loopback, just like when multicast loopback.

itojun 4f1c7f0bbe do not try NUD unless the gateway is a real neighbor.
real fix to KAME PR 245 (workaround has been implemented).

itojun 3e34240544 perform neighbor unreachability detection on p2p links (spec requires
it for bidir p2p links).
improve -i in ndp(8) to allow tweaking per-interface ND flag on.
fix ndp(8) infinite loop on certain routing table setup.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

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 f91ee608a9 avoid calling in6_control(SIOCDIFADDR_IN6) from interrupt context.
it is not supposed to work.
logging fix: add "\n" to some of log() in in6_prefix.c.

improve in6_ifdetach().  now almost all structure depend on ifnet
will be cleared up.
possible loose ends:
- cached route_in6 in static varaiables needs to be cleared as well
- there are ifaddr manipulation without reference counting,
  which should be fixed
we still see panics after card removal, though...  not sure what is left.

itojun b3761abef8 remove extra portability #ifdef (like #ifdef __FreeBSD__) in KAME IPv6/IPsec
code, from netbsd-current repository.
#ifdef'ed version is always available from ftp.kame.net.

XXX please do not make too many diff-unfriendly changes, we'll need to take
bunch of diffs on upgrade...

itojun ea861f0183 sync IPv6 part with latest KAME tree. IPsec part is left unmodified
due to massive changes in KAME side.
- IPv6 output goes through nd6_output
- faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator
  using heavily modified DNS servers
- per-interface statistics (required for IPv6 MIB)
- interface autoconfig is revisited
- udp input handling has a big change for mapped address support.
- introduce in4_cksum() for non-overwriting checksumming
- introduce m_pulldown()
- neighbor discovery cleanups/improvements
- netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland)
- IFA_STATS is fixed a bit (not tested)
- and more more more.

TODO:
- cleanup os-independency #ifdef
- avoid rcvif dual use (for IPsec) to help ifdetach

(sorry for jumbo commit, I can't separate this any more...)

itojun 70ada0957e sync with recent KAME.
- loosen ipsec restriction on packet diredtion.
- revise icmp6 redirect handling on IsRouter bit.
- tcp/udp notification processing (link-local address case)
- cosmetic fixes (better code share across *BSD).
