036f8336fa mdoc(7) police: replace two -unfilled displays with -tag lists. 
This works only because of bugs in current implementation: the
first .It after ``.Bd -unfilled'' re-enables filling mode and
does not restore (disable) it back afterwards.

7f89db65f5 Add a ``Usable'' function to the ccp switch. The function 
is called prior to sending a CCP configure request for a
given protocol.  The default is to send the request, but
this is overridden for MPPE which checks to see if the lcp
negotiations agreed CHAP81, and if not fails.

Use the same function to decide if we should reject peer
requests for MPPE.

This should get rid of those boring messages about not being
able to initialise MPPE when we don't negotiate CHAP81.

2fc2f70582 Untangle some cunfusion between the CLOSE_STAYDOWN, CLOSE_LCP and 
CLOSE_NORMAL meanings.  CLOSE_NORMAL doesn't change the currently
required state, the others do.  This should stop ppp from entering
DATALINK_READY when LCP shutdown doesn't end up happening cleanly.

Bump our version number to reflect this change.

542962ddf9 Introduce another global (MPPE_IsServer) so that we initiate the 
MPPE session keys correctly.

I'm a bit dubious about this code.  It seems that the session keys
are initialised differently based on whether you're the client or
the server.  One side is the server if it issues the first challenge,
but of course you can issue a challenge from both sides.... at the
same time.  Sounds like another wonderful M$ assumption...

Ppp can now talk to itself correctly using encryption.

91cbd2eec0 Maintain input and output throughput averages and choose the highest 
of the two when calculating the MP throughput average for the ``set
autoload'' implementation.

This makes more sense as all links I know of are full-duplex.  This
also means that people may need to adjust their autoload settings
as 100% bandwidth is now the theoretical maximum rather than 200%
(but of course, halfing the current settings is probably not the
correct answer either!).

This involves a ppp version bump as we need to pass an extra
throughput array through the MP local domain socket.

11572abf62 Calculate the average link throughput using a counter based on the

total of PROTO_MP traffic.

9825166754 o Log the (payload/size) of all packet types, not just TCP packets 
o  If the new ``filter-decapsulation'' is enabled, delve into UDP packets
   that contain 0xff 0x03 as the first two bytes, and if we recognise it
   as PROTO_IP, decapsulate it for the purpose of filter checking.

   If we recognise it as PROTO_<anything else> mention this for logging
   purposes only.

This change is aimed at people running PPPoUDP where the UDP traffic is
being sent over another PPP link.  It's desireable to have the top level
link connected all the time, but to have the bottom level link capable
of decapsulating the traffic and comparing the payload against the filters,
thus allowing ``set filter dial ...'' to work in tunnelled environments.

The caveat here is that the top ppp cannot employ any compression layers
without making the data unreadable for the bottom ppp.  ``disable deflate
pred1 vj'' and ``deny deflate pred1 vj'' is suggested.

c8f30703cd I didn't get this right the last time.... 
When an NCP reaches TLF, *ONLY* datalink_Close() links that are
in DATALINK_OPEN.

When the last link reaches TLD, DOWN all NCPs (as we used to in the
links TLF (which was the wrong place anyway)), as the NCPs aren't
now going to datalink_Close() us unexpectedly, we get to continue
doing what we were told to do in the first place.

The result:  When we lose a link, the IPCP layer goes down and
we actually call the stuff in ppp.linkdown !

It was not a good idea to remove csu_header from struct cspace, it had
ramifications which I didn't notice.

Restore src/usr.sbin/ppp/slcompress.h to the way it was, since MAX_HDR
was already defined as 128 there and it's a user program anyway.

In sys/net/slcompress.h make MAX_HDR 128 intead of MLEN to avoid
bloat.

5a8b6a98df If a links LCP FSM has reached TLF and it's the last link, 
don't bother to re-initialise the NCPs.  Instead wait for
bundle_LinkClosed() to be called - IFF it actually is called.

By initialising the NCPs at this point, ppp was recursing
back into the fsm_Down() routing for the link, and losing
track of the reason that the link was being brought down.
The end result was that ``set reconnect'' would never do
anything.

3ce91245fc Do some vfork() trickery so that the parent can determine 
if the childs exec() has succeeded or failed by taking advantage
of the fact that both processes share the same memory.

FWIW:
  I tried to implement this by doing a pipe(), setting the
  write desciptors close-on-exec flag in the child and writing
  errno to the descriptor if the exec() fails.  The parent can
  then ``if (read()) got errno else exec worked''.

  This didn't work though - the child could write() to fd[1] on
  exec failure, but the parent got 0 trying to read() from fd[0] !
  Is this a bug in execve() ?

76ce2d4bcb When adjusting timer::rest, round to the closest TICKUNIT usecs

This has minimal impact here, but if ppp ever needs to frequently
remove timers before they've timed out, it can badly skew the next
item in the timer list without this change.

The correct fix would be to store usecs in `rest' rather than
TICKUNITs, but the math is easier if we just round...
