1/ is compatible with the old route(1) in case needed.
2/ actually fixes the problem while vetting bad user input.
note: I have already fixed route(1) so the problem shouldn't occur.
if it does. use 0.0.0.0/0 instead of the word 'default' :)
We need to accept at least one sockaddr with zero length, in order
to be able to set the default route.
Suggested by: Phone conversation with Julian (sleep well!)
Route(1) has a bug that sends a bad message to the kernel. The kernel
trusts it and crashes. Add some sanity checks so that
we don't trust the user quite as much any more.

1: cvs and cvsup don't really support vendor branches other than 1.1.1.x,
this is on 1.1.2.x and causing problems in cvsup 'checkout mode', just the
same as cvs has problems interpreting dates. (cvs has "1.1.1" hard coded)
2: cvs 'rm'ing them takes them off the vendor branch and should hide the
above problems.
3: it's just clutter until the merge is done.
4: if the problem isn't sufficiently resolved by taking these off the
vendor branch, the files will have to be nuked and re-imported.

davidg spotted this in usr.sbin/ppp/slcompress.c
a while ago, but I believe gave the wrong reasons -
it's too easy to reproduce ! The only scenario that
I've been able to reproduce the problem under is when
m_len is *exactly* 40 ! So go figure !

Remove previous hack in pppfcs().
This is still not the correct solution. We shouldn't
have any incorrect mbufs. This patch does however make
pppd/natd work (rather than jamming the interface).
so don't enforce the MTU as an MRU. Allow bidirectional ppp MTU
negotiation, by checking against a differnt figure for MRU.
Make it large enough for ATM frames at least.

interrupt mask hackery wasn't happening when being modloaded via the
if_ppp lkm. It seems that the lkm system doesn't particularly like having
two sets of load/unload/etc routines. :-] This really should be fixed
by having a seperate if_ppp and ppp_tty lkm, but that requires that ppp_tty
is loaded after if_ppp, and needs to be able to link with symbols in
if_ppp. This gets messy, it is a better task for the in-kernel linker.
(if_ppp is generic, ppp_tty is a tty-specific bottom end for if_ppp, it's
not _too_ hard to have another "provider" (such as a hdlc sync card)
connected to if_ppp)

Minor problem: don't choke with ENETDOWN early. As long as our output

full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols. I needed
this to provide PPP support for the BISDN project (right now).
Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer. This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events). Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles. Please report if i broke
something in the existing drivers.
For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

This commit includes the following changes:
1) Old-style (pr_usrreq()) protocols are no longer supported, the compatibility
glue for them is deleted, and the kernel will panic on boot if any are compiled
in.
2) Certain protocol entry points are modified to take a process structure,
so they they can easily tell whether or not it is possible to sleep, and
also to access credentials.
3) SS_PRIV is no more, and with it goes the SO_PRIVSTATE setsockopt()
call. Protocols should use the process pointer they are now passed.
4) The PF_LOCAL and PF_ROUTE families have been updated to use the new
style, as has the `raw' skeleton family.
5) PF_LOCAL sockets now obey the process's umask when creating a socket
in the filesystem.
As a result, LINT is now broken. I'm hoping that some enterprising hacker
with a bit more time will either make the broken bits work (should be
easy for netipx) or dike them out.

Add definitions for the 802.3/Ethernet MIB. To implement this, simply
add a `struct ifmib_iso_8802_3' somewhere in your interface's softc,
point if_linkmib to it, set if_linkmiblen, and fill in the statistics
with appropriate values. (I didn't want to create Yet Another Ethernet-

This is a patch to sys/net/if.c. What it does is patch the algorithm
for finding an IP address on an interface which most closely matches
a given IP address. The problem with it is when no address matches,
and you have to just pick one at random. Then the code ends up picking
the last IP address in the list. This patch changes things so it
picks up the first address instead.
Usually the first address is more useful as the later ones are aliases.

of the MIB; one contains (essentially) `ifdata' structures, and the other
contains a blob provided by the interface (and presumably used to
implement link-layer-specific MIB variables). A number of things
have been moved around in the `ifnet' and `ifdata' structures, so

The old system had the misfeature that the only policy it could implement
was tail-drop; the new IF_ENQ_DROP macro/function makes it possible
to implement more sophisticated queueing policies on a system-wide
basis. No code actually uses this yet (although on my machine
I have converted the ethernet and (polled) loopback to use it).
