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.

kleink 241f6932ee * Use uint{8,32}_t from <netinet/in.h> where applicable; use private
fixed-width integer types otherwise.
* Protect RFC 2292 prototypes, which are not XNS5.2/POSIX-2001; also, define
  size_t for inet6_rthdr_space().

thorpej ad9d3794b0 Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

darrenr fd7edad6c3 Change the use of pfil hooks. There is no longer a single list of all
pfil information, instead, struct protosw now contains a structure
which caontains list heads, etc.  The per-protosw pfil struct is passed
to pfil_hook_get(), along with an in/out flag to get the head of the
relevant filter list.  This has been done for only IPv4 and IPv6, at
present, with these patches only enabling filtering for IPPROTO_IP and
IPPROTO_IPV6, although it is possible to have tcp/udp, etc, dedicated
filters now also.  The ipfilter code has been updated to only filter
IPv4 packets - next major release of ipfilter is required for ipv6.

itojun 59d74f3d21 to improve RFC2553/2292 compliance, and promote use of
RFC2553/2292-compliant header file path, now the following headers are
forbidden:
	netinet6/ip6.h
	netinet6/icmp6.h
	netinet6/in6.h

if you want netinet6/{ip6,icmp6}.h, use netinet/{ip6,icmp6}.h.

if you want netinet6/in6.h, you just need to include netinet/in.h.
it pulls it in.
(we may need to integrate them into netinet/in.h, but for cross-BSD code
sharing i'd like to keep it like this for now)

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 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).

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...)

kleink dd24133620 Take a stab at namespace protection. For now, only the obvious problems are
addressed, the culprit being the lack of a namespace definition for an IPv6-
extended <netinet/in.h> in XNS5.2 D2.0; I'll try to work something out and
submit it to the review WG.
1999-07-03 14:04:57 +00:00
itojun f8346292af move ipsec sysctl index to IPPROTO_AH (instead of IPPROTO_ESP),
so that you can perform sysctl operation when ESP is not compiled in.

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.
