itojun ae5499819c reduce diffs with kame (mostly cosmetic).
move IPV6_CHECKSUM processing to sys/netinet6/raw_ip6.c.
constify a couple of places.

itojun e1f4f77960 to sync with kame better, (1) remove register declaration for variables,
(2) sync whitespaces, (3) update comments. (4) bring in some of portability
and logging enhancements.  no functional changes here.

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.

itojun e2d658087d move ia6->ia6_dad_ch to dp->dad_timer_ch, to ease KAME code sharing.
now in6_var.h does not need to pull sys/callout.h in.

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 8f5a83e6e9 on SIOCS*_IN6, validate sockaddrs so that we never configure non-AF_INET6
addresses. (in_control has the same problem - I'll need to check it as well)

obsolete the following two ioctls, they do not fit well against IPv6 addressing
model. (the kernel support them for some period of time, we'll remove them
in the near future)
	SIOCSIFDSTADDR_IN6
	SIOCSIFNETMASK_IN6
2000-02-25 05:13:05 +00:00
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.

(sync with kame)

thorpej c1185c1020 PRU_PURGEADDR -> PRU_PURGEIF, per a discussion w/ itojun. In the IPv4
and IPv6 code, also use this to traverse PCB tables, looking for cached
routes referencing the dying ifnet, forcing them to be refreshed.

itojun f5fba17f1b implement in6_purgemkludge(). in6_ifdetach() calls it to avoid dangling
kludge entries.  the situation would occur if you take the following steps:
- join multicast groups (default ones like linklocal all-node is fine)
- remove all IPv6 addresses manually
- remove pcmcia card

to thorpej: pls call in6_ifdetach() when PRU_PURGEIF is raised (just before
removing ifnet).  it should do the right thing (unable to perform real test
though)

thorpej d844a3ac41 First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
  work was.  This is hard to get right, and we should attack one
  protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
  purge an ifaddr from a protocol.  The old method Bill used didn't work
  on all protocols, and it only worked on some because it was Very Lucky.

This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

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 76fc599a8d change unnecessary u_long/long into u_int32_t or something relevant.
