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

itojun 1990d680c4 do not change neighbor cache state on entry timeout,
if the cache entry is for outgoing router.

perform on-linkness check before default router (re-)seletion.

do not play with interface direct route on nd6_rtrequest.

sync a lot of cosmetic changes.  sync with kame

itojun 1bc6ca28a1 make sure to clean ln_byhint on reachability confirmation. 2001-02-11 07:00:03 +00:00
itojun 22b473e0f6 during ip6/icmp6 inbound packet processing, do not call log() nor printf() in
normal operation (/var can get filled up by flodding bogus packets).
sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages.
(#define ND6_DEBUG will turn it on by default)

improve stats in ND6 code.

lots of synchronziation with kame (including comments and cometic ones).

itojun 617b3fab7e - record IPsec packet history into m_aux structure.
- let ipfilter look at wire-format packet only (not the decapsulated ones),
  so that VPN setting can work with NAT/ipfilter settings.

TODO: use header history for stricter inbound validation

onoe e83458422f First Prototype implementation of network interface part for IEEE1394 (if_fw).
Current status:
	Only OHCI chip is supported (fwohci).
	ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
	sometimes works but not stable.
Not implemented yet:
	IRM (Isochronous Resource Manager) functionality.
	Link layer fragmentation.
	Topology map.
More to do:
	clean ups
	MCAP
	charactor device part
	dhcp

There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.

itojun fa5c89d64a do not mistakingly forward link-local scoped packet (the bug was added
with "beyondscope" icmp6 support).
"options FAKE_LOOPBACK_IF" will honor scope on loopback outputs.  rcvif will
be real interface, not the loopback, just like when multicast loopback.

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.
2000-03-24 04:09:04 +00:00
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.

thorpej 2ac45d6eef Quiet down the DAD messages a little more. 2000-03-16 02:53:45 +00:00
itojun 04ac848d6f introduce m->m_pkthdr.aux to hold random data which needs to be passed
between protocol handlers.

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing.  this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.

due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.

take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).

this will bump kernel version.

(as discussed in tech-net, tested in kame tree)

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.
2000-02-26 08:39:18 +00:00
itojun 49bed394bd add more sanity check against mbuf length.
use log() for DAD related kernel message.

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

thorpej 011b02e348 Clean up some printfs(), and mark a few for possible later nuking,
since they appear to be for debugging purposes only.

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