0229106442 Exchange whole structures on SUNIT, not unit+flags fields only.
It is needed because if_attach() assumes fixed units order
and pass it to ifconfig

076d0761c4 An actual fix for the routing default crashes that
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' :)

9a969a6e41 Fix Julian's fixed fix. Routing is weird.
We need to accept at least one sockaddr with zero length, in order
to be able to set the default route.

7f33a738c1 Finally track down the reason for some of my occasional kernel crashes.
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.

7a43952972 Send these files to the attic until they are in use for several reasons.
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.

3bb3b0463e Fix this damn mbuf with a negative m_len. It turns
out to be a problem with VJ header compression.
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 !

443e72b45a Protect against garbage mbufs in pppstart.
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).

a353ca89cd Bruce mentioned to me that Paul Traina had noticed that the ppp_tty
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)

07f0846feb Major nit: i've confused link0 and link1 in my brain and/or in either
the man page or the source file.  Fix this.

Minor problem: don't choke with ENETDOWN early.  As long as our output
queue has space, put the IP packets there even if IPCP ain't up yet.
We will eventually be able delivering them once the PPP state machine
came up.

00081cc989 Major overhaul of the SyncPPP layer. Basically, this comprises now a
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.

db99d43f6f Make sppp's logging human-readable. Also, use log(9), as opposed to
printf(9), so the log output doesn't clutter the console.

While i was at it, KNFified some function definitions.  This file was
very inconsistent in this respect.

a29f300e80 The long-awaited mega-massive-network-code- cleanup. Part I.
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.

to -current.

Thanks goes to Ulrike Nitzsche <ulrike@ifw-dresden.de> for giving me
a chance to test this.  Only the PCI driver is tested though.

One final patch will follow in a separate commit.  This is so that
everything up to here can be dragged into 2.2, if we decide so.
