itojun 1ff38f4d03 on interface removal, remove multicast groups joined from pcb, before
removing interface addresses.  without the change, we may deref
NULL pointer in in_pcbpurgeif().  from jinmei@kame, sync with kame

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.

itojun 1a2a1e2b1f bring in latest KAME ipsec tree.
- interop issues in ipcomp is fixed
- padding type (after ESP) is configurable
- key database memory management (need more fixes)
- policy specification is revisited

XXX m->m_pkthdr.rcvif is still overloaded - hope to fix it soon

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.

lukem a1ea50ee45 * in_pcblookup_port(): deprecate INPLOOKUP_WILDCARD and flags in favour
of a lookup_wildcard arg; simplifies the logic a bit.
* when assigning ephemeral ports in in_pcbbind(), always call
  in_pcblookup_port() with lookup_wildcard=1, so that ephemeral port
  allocation on sockets with SO_REUSEADDR set won't potentially bind to a
  port in use by something else (principle of least surprise).

matt f070ddb8ed Move the ppcb pointer towards the front of the structure so that it and the
pcb chain pointers can possibly be in the same cache line.

perry f73530ba55 add/cleanup multiple inclusion protection. 1998-02-10 01:26:19 +00:00
lukem c80b4400e5 add the following, derived from FreeBSD:
* IP_PORTRANGE socket option, which controls how the ephemeral ports
  are allocated. it takes the following settings:
	IP_PORTRANGE_DEFAULT	use anonportmin (49152) -> anonportmax (65535)
	IP_PORTRANGE_HIGH	as IP_PORTRANGE_DEFAULT (retained for FreeBSD
				compat reasons, where these are separate)
	IP_PORTRANGE_LOW	use 600 -> 1023. only works if uid==0.
* in_pcb flag INP_ANONPORT. set if port was allocated ephmerally

matt 8c42ff649b Add support for returning maximum supported MTU when ip_output fails with
EMSGSIZE.

thorpej de572198ad Implement in_pcbrtentry() - return the route associated with a PCB. If
one does not exist, attempt to allocate one.  This is mostly pulled from
tcp_input.c.

thorpej efa8881dbe Pull SYN_cache_branch down into the main line. 1997-07-23 21:26:40 +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.

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.

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 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.
