ed0af9bc44 Allow interfaces to be attached to bpf at times other than boot.
doing so without this patch leads to an infinite loop in the kernel.

7ed8f465e7 Add a per-interface-address pointer to a function that can be supplied
by a protocol, to detirmine if an address matches the net this address
is part of.  This is needed by protocols for which netmasks
"just don't work", for example appletalk.

Also add the code in appletalk to make use of this new feature.
Thsi fixes one of the longest standing bugs in appletalk.
The inability to talk to machines to which the path is via a router
which is on a different net, but the same netrange, as your interface.
Protocols that do not supply this function (e.g. IP) should not be affected.

2d4b190bc5 Update kernel parts of pppd from 2.2.0 to 2.3.0. I've yet to look at the
2.3.0 -> 2.3.1 changes, but I seem to recall that there are certain
"issues" with 2.3.1 (I'm not sure if it's just pppd or the whole lot, I
am not quite that far).  The present pppd seems to work with it just fine
for the time being.

Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.

57bf258e3d Fix all areas of the system (or at least all those in LINT) to avoid storing
socket addresses in mbufs.  (Socket buffers are the one exception.)  A number
of kernel APIs needed to get fixed in order to make this happen.  Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead.  Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.

2c060c765a Fix a traceroute problem in the CISCO HDLC mode. (cisco routers not
returning ICMP_TIMXCEED)

use CISCO_UNICAST instead of CISCO_MULTICAST to send normal packets.
this is needed for packets to get processed by a cisco router,
but doesn't matter if a packet is just forwarded.

1/ is compatible with the old route(1) in case needed.
2/ actually fixes the problem while vetting bad user input.

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)

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.
