itojun b360c656a0 temporary workaround against GIF NUD issue (when you configure globals
onto GIF, NUD prevents packet from going out)
KAME PR 245.  From: Andreas Wrede <andreas@planix.com>
2000-04-27 00:33:47 +00:00
itojun 5393e61dd0 add boundary check for nd6_ifinfo (otherwise ndp -i can make out-of-bound
accesses).
2000-04-19 07:13:03 +00:00
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 18f9d539cc even if nd6_nud_hint is called, do not change a neighbor's status
unless the old status is probably reachable (i.e. the link-layer address
has already been resolved).
KAME PR 235.

itojun ecb5f2e56a revisit in6_ifattach().
- be persistent on initializing interfaces, even if there's manually-
  assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel.  grab mac addr from existing cards
  (this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!

call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.

(the change is in sync with kame tree).

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 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 90736ab608 fix include pathname for better rfc2292 compliance. 2000-02-06 12:49:37 +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.

itojun 54cb3be873 remove #if 0'ed code 2000-02-03 12:50:05 +00:00
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 486d64de0f add missing splx(). a critical bug fix from kame. 1999-12-10 17:56:13 +00:00
itojun 62c568fac4 tiny fix to ARCnet IPv6 support.
- in in6_ifattach_getifid(), we can grab interface id source iff the source
  is universally (worldwide) unique.  ARCnet hardware address is of 8bit and
  does not satisfy the condition.
  (in6_ifattach_getifid() is for getting interface id usable for pseudo
  interfaces like gif*)
- xx_to_eui64() should return EUI64 format, not IPv6 interface id format.
  this may seem awkward so I wish to clean these things up.
- in nd6.c, change if clause into case clause to allow future addition
  of IFT_xxx easier.

is 6a793d8a47 Zeroth version of IPv6 support for ARCnet. Correct MTU handling still needs
to be done.

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).

itojun 06c350054d remove reference to in6_systm.h (file itself will be removed afterwords) 1999-07-30 10:35:34 +00:00
itojun dcc13cdd33 sync with KAME/NetBSD 1.4, SNAP kit 19990705.
key changes are:
- icmp6 redirect fix (dst check)
- revised ip6 multicast check for loopback i/f
- several RCS ID cleanups

itojun 9b74747370 s/splnet/splsoftnet/ in IPv6/IPsec part.
hope I made no mistake (the kernel works fine but I need a regress test)
