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

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).
2000-07-06 12:36:18 +00:00
itojun 3909133548 introduce sys/netinet/ip_encap.c, to dispatch inbound packets
to protocol handlers, based on src/dst (for ip proto #4/41).
see comment in ip_encap.c for details of the problem we have.
there are too many protocol specs for ip proto #4/41.
backward compatibility with MROUTING case is now provided in ip_encap.c.

fix ipip to work with gif (using ip_encap.c).  sorry for breakage.

gif now uses ip_encap.c.

introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code
with ip proto #41).
2000-04-19 06:30:51 +00:00
itojun 99d909fc98 implement rip6_ctlinput, to cope with routing changes correctly.
(IMHO we need rip_ctlinput as well)
2000-02-26 09:09:17 +00:00
itojun 9c484862a0 make it possible to throw IPv6 packet with proto=4/41.
(in normal case we don't do it, but this is how IPv4 in_proto is written)

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...
2000-01-06 15:46:07 +00:00
itojun 2e904aec57 make IPV6_BINDV6ONLY setsockopt available. it controls behavior of
AF_INET6 wildcard listening socket.  heavily documented in ip6(4).
net.inet6.ip6.bindv6only defines default value.  default is 1.

"options INET6_BINDV6ONLY" removes any code fragment that supports
IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).
2000-01-06 06:41:18 +00:00
itojun 07c2fe1cd9 add net.inet6.icmp6.nodeinfo sysctl.
this allows you to disable/enable ICMPv6 node information query/reply
processing (which tells remote end the gethostname(3) setting, interface
addresses on the node, and some other things - documented in
draft-ietf-ipngwg-icmp-name-lookup* or something alike).

to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1.
(sync with kame change)

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)

explorer ed3b6d5791 Fix a problem where tcp_slowtimo was called twice, once for ipv4 tcp and
once for ipv6.  This patch makes the ipv6 case pass NULLs in for fast
and slow timeouts iff defined(INET) and passes in the right function
if !defined(INET).

itojun 118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.
