itojun dc0f1c0435 drop IPv6 packets with v4 mapped address on src/dst. they are illegal
and may be used to fool IPv6 implementations (by using ::ffff:127.0.0.1 as
source you may be able to pretend the packet is from local node)

itojun abddb5f851 do not overwrite traffic class field when we write IPv6 version field. 1999-12-15 06:28:43 +00:00
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 6b9bfc0691 - Call in{,6}_pcbdetach if ipsec initialization is failed during PRU_ATTACH.
This situation happens on severe memory shortage.  We may need more
  improvements here and there.
- Grab IEEE802 address from IFT_ETHER card, even if the card is
  inserted after bootup time.  Is there any other card that can be
  inserted afterwards?  pcmcia fddi card? :-P
- RFC2373 u bit handling suggests that we SHOULD NOT copy interface id from
  ethernet card to pseudo interface, when ethernet card has IEEE802/EUI64
  with u bit != 0 (this means that IEEE802/EUI64 is not universally unique).
  Do not use such address as, for example, interface id for gif interface.
  (I have such an ethernet card myself)
  This may change interface id for your gif interface.  be careful upgrading
  rc files.

(sync with recent KAME)

itojun 6d8996ba49 import recent kAME fixes.
- initialize hoplimit for raw6 socket properly.
- respect SO_TIMESTAMP on udp6.
- more sanity checks.

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 869f140395 fix IPV6_CHECKSUM socket option (length computation was wrong). 1999-07-19 18:37:19 +00:00
thorpej f9a7668b3f defopt IPSEC and IPSEC_ESP (both into opt_ipsec.h). 1999-07-09 22:57:15 +00:00
itojun 6ea6ccf105 checked build on alpha and i386, with GENERIC.v6.
fixed several sizeof(void *) and sizeof(size_t) issues on alpha.

Thanks to: Dave Huang and Tim Rightnour

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

itojun 74d3c214ec KAME/NetBSD 1.4 SNAP kit, dated 19990628.
NOTE: this branch (kame) is used just for refernce.  this may not compile
due to multiple reasons.
