thorpej c1185c1020 PRU_PURGEADDR -> PRU_PURGEIF, per a discussion w/ itojun. In the IPv4
and IPv6 code, also use this to traverse PCB tables, looking for cached
routes referencing the dying ifnet, forcing them to be refreshed.

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 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.

thorpej 788dee365c Sigh, fix some broken logic in the last change to INADDR_TO_IA(), and make
the macro a little more obvious.  Should fix kern/7589, from Jens A Nilsson.

thorpej a40dff106e In INADDR_TO_IA(), skip interfaces which are not up. Revert previous change
to ip_input.c to check the interface status after INADDR_TO_IA().

Fix cooked up by Heiko Rupp and myself.

Fixes PR 7480.

tls c4730d65cf Switch order of TNF and UCB copyrights so UCB copyright is first; this seems more appropriate since UCB wrote the original code, after all. 1998-09-30 21:52:24 +00:00
scottr e3e7e1673f Fix the NEXT_IA_WITH_SAME_ADDR macro introduced in 1.27: it was finding
the first in_ifaddr structure with a different internet address!  Reverse
the sense of the test.  Spotted by and fix from Eric Haszlakiewicz.

tls 31d0752b99 change IN_IFADDR_HASH_SIZE to 509, which actually uses no more space than 293 due to rounding up to nearest power of two in hashinit. 1998-07-29 05:18:54 +00:00
tls deac3540de Put original hash function back. It wastes a little bit of space, but is much more even -- think of the case of a web service provider, some of whose customers end up getting 'inferior service' because they're on addresses that happen to be out at the end of a hash chain. With webservers with thousands of addresses, this is a real issue. If the wasted space is a big deal, we could pick a prime number that's slightly _less_ than a power of two... 1998-07-16 06:45:09 +00:00
is d8b8a41918 The rewrite of if_arp.c to work with the hashed interface address lists
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).

The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.

We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.

thorpej 837a8317b5 Eek, we were wasting almost half of the in_ifaddr hash space by modulo'ing
with IN_IFADDR_HASH_SIZE.  Instead, AND with the hash mask computed by
hashinit().

dotted quad format instead of hex.

matt 36eac04cc0 Default IP flow to being enabled. Add a sysctl to control the maximum
number of flows (net.inet.ip.maxflows).  If set to 0, will disable fast
path forwarding.
1998-05-04 19:24:53 +00:00
matt d4d709f7d0 Add support for "fast" forwarding. Add hooks in if_ethersubr.c and
if_fddisubr.c to fastpath IP forwarding.  If ip_forward successfully
forwards a packet, it will create a cache (ipflow) entry.  ether_input
and fddi_input will first call ipflow_fastforward with the received
packet and if the packet passes enough tests, it will be forwarded (the
ttl is decremented and the cksum is adjusted incrementally).
