Peter Wemm 3c6b084e96 Finish driving a stake through the heart of netns and the associated
ifdefs scattered around the place - its dead Jim!

The SMB stuff had stolen AF_NS, make it official.

Bruce Evans 34fe62c776 Fixed some style bugs in the removal of __P(()). The main ones were
not removing tabs before "__P((", and not outdenting continuation lines
to preserve non-KNF lining up of code with parentheses.  Switch to KNF
formatting and/or rewrap the whole prototype in some cases.

Ruslan Ermilov 8071913df2 Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
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.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Jayanth Vijayaraghavan e7f3269307 When a connection is being dropped due to a listen queue overflow,
delete the cloned route that is associated with the connection.
This does not exhaust the routing table memory when the system
is under a SYN flood attack. The route entry is not deleted if there
is any prior information cached in it.

Peter Wemm 664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

Mike Smith 64e41ba7c8 Increase the size of the route reference count from 15 bits to 31 bits.
This doesn't change the size or alignment of the structure on either i386
or Alpha, and thus should be binary-compatible (modulo problems with old
applications and routes with more than 2^15 references).

Garrett Wollman 477180fbc8 Use the new if_multiaddrs list for multicast addresses rather than the
previous hackery involving struct in_ifaddr and arpcom.  Get rid of the
abominable multi_kludge.  Update all network interfaces to use the
new machanism.  Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).

Garrett Wollman 9f9b3dc4ae Add three new route flags to help determine what sort of address
the destination represents.  For IP:

- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
  (belongs to this host) and broadcast addresses, respectively.

- For all routes, RTF_MULTICAST is set if the destination is multicast.

The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments.  All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:

	(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
	== RTF_HOST

Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.

it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

delete them when the ``parent'' goes away

route.h: add glue to track this to rtentry structure.  WARNING WILL ROBINSON!
This will be yet another incompatible change in your route-using binaries.
I apologize, but this was the only way to do it.  I took this opportunity
to increase the size of the metrics to what I believe will be the final
length for 2.1, so that when the T/TCP stuff is done, this won't happen
again.

Garrett Wollman 995add1a12 Add support for two separate cloning flags, one set by the lower layers,
and one set by the protocol family.  Also add another parameter to
rtalloc1() to allow for any interface flags to be ignored; currently
this is only useful for RTF_PRCLONING.  Get rid of rt_prflags and re-unite
with rt_flags.  Add T/TCP ``route metrics''.

NB: YOU MUST RECOMPILE `route' AND OTHER RELATED PROGRAMS AS A RESULT OF
THIS CHANGE.

This also adds a new interface parameter, `ifi_physical', which will
eventually replace IFF_ALTPHYS as the mechanism for specifying the
particular physical connection desired on a multiple-connection card.

NB: YOU MUST RECOMPILE `ifconfig' AND OTHER RELATED PROGRAMS AS A RESULT OF
THIS CHANGE.
