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.

mycroft 7eeb5a04da Don't screw with ip_len; just subtract from it where we actually use the 
value.
 1999-01-19 23:03:20 +00:00
mycroft fc1211a6ab Don't overwrite the checksum fields when checking them. There's no reason to 
do this, and it screws up ICMP replies.
XXX The returned IP checksum and length are still wrong.
 1999-01-19 21:58:40 +00:00
thorpej 555784ccd5 Fix byte order and ip_len inconsistencies in ICMP reply code. Also, fix 
some formatting and HTONS(foo) vs. foo = htons(foo) inconsistencies.

PR #6602, Darren Reed.

thorpej e5e283e02d Finishing merging 4.4BSD-Lite2 netinet. At this point, the only changes 
left were SCCS IDs and Copyright dates.

drochner d8f1d9401e Adjust packet len in mbuf header for incoming broadcasts. 
Closes PR kern/4087 (by myself).

thorpej db103f4414 Make the following tunable via sysctl, inspired by BSD/OS: 
- udp_sendspace
- udp_recvspace
 1997-07-28 22:19:53 +00:00
thorpej 9bf15b8b78 Don't adjust ip->ip_len before calling icmp_error(); icmp_error() already 
does this.  Per Stevens in TCP/IP Illustrated Vol. 2, p.774, submitted
by Koji Imada <koji@math.human.nagoya-u.ac.jp>.
 1997-06-24 19:31:34 +00:00
thorpej 9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

thorpej 096b0d6c6e In udp_output(), sanity check the length of the packet to be transmitted. 
If it's larger than IP_MAXPACKET, return an error condition.

mycroft 62a6cce9ca Add in_nullhost() and in_hosteq() macros, to hide some protocol 
details.  Also, fix a bug in TCP wrt SYN+URG packets.

mycroft 9347e648d8 udp_output() doesn't actually take control data, so don't pretend it does. 1996-05-23 17:05:45 +00:00
mycroft f399db63a4 Make sure the control mbufs are freed in all cases. 1996-05-23 17:03:27 +00:00
mycroft 60395beed8 Fix a race condition in PRU_DISCONNECT. 
Rearrange the code to deal with unconnected sockets slightly.
Other minor changes.

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and 
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.

mycroft 67e78477db Build a hash table of PCBs. Hash function needs tweaking. 1996-01-31 03:49:23 +00:00
cgd dfad729a16 make netinet work on systems where pointers and longs are 64 bits 
(like the alpha).  Biggest problem: IP headers were overlayed with
structure which included pointers, and which therefore didn't overlay
properly on 64-bit machines.  Solution: instead of threading pointers
through IP header overlays, add a "queue element" structure to do
the threading, and point it at the ip headers.

cgd f90cf78fba convert pcb lists to CIRCLEQs, so that the end can be looked at more 
easily, and so that the original (insque/remque) logic can be effectively
mimiced.  (This fixes a bug in the previous set of list changes.)
also (since terminator is no longer null) reinstate uninitted list checks,
but mark them XXX.

mycroft 10a4696964 Oops. Make source quench work again. 1995-06-12 06:24:21 +00:00
mycroft 6897f39ae9 Various cleanup, including: 
* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.
