* Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.Ruslan Ermilov2001-10-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *'' as the argument. Pass rt_addrinfo all the way down to rtrequest1 and ifa->ifa_rtrequest. 3rd argument of ifa->ifa_rtrequest is now ``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is using it anyways). Benefit: the following command now works. Previously we needed two route(8) invocations, "add" then "change". # route add -inet6 default ::1 -ifp gif0 Remove unsafe typecast in rtrequest(), from ``rtentry *'' to ``sockaddr *''. It was introduced by 4.3BSD-Reno and never corrected. Obtained from: BSD/OS, NetBSD MFC after: 1 month PR: kern/28360 Notes: svn path=/head/; revision=85074

| | | | | | | | | | | | | | | | | | | | | This work was based on kame-20010528-freebsd43-snap.tgz and some critical problem after the snap was out were fixed. There are many many changes since last KAME merge. TODO: - The definitions of SADB_* in sys/net/pfkeyv2.h are still different from RFC2407/IANA assignment because of binary compatibility issue. It should be fixed under 5-CURRENT. - ip6po_m member of struct ip6_pktopts is no longer used. But, it is still there because of binary compatibility issue. It should be removed under 5-CURRENT.

* Lock down the network interface queues. The queue mutex must be obtainedJonathan Lemon2000-11-251-17/+9
| | | | | | | | | | | | | | | | | before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex. IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.

| | | | | | | | | | | | | | | | | | | Remove lots'o'hacks. looutput is now static. Other callers who want to use loopback to allow shortcutting should call the special entrypoint for this, if_simloop(), which is specifically designed for this purpose. Using looutput for this purpose was problematic, particularly with bpf and trying to keep track of whether one should be using the charateristics of the loopback interface or the interface (e.g. if_ethersubr.c) that was requesting the loopback. There was a whole class of errors due to this mis-use each of which had hacks to cover them up. Consists largly of hack removal :-) Notes: svn path=/head/; revision=36908
