448374baae Bring the interface IFF_UP from ipcp_InterfaceUp() (called from IPCP's 
TLU event handler).

This used to be done as a side effect of SIOCAIFADDR'ing the interface,
but now that duplicate SIOCAIFADDRs are optimised out, we can't depend
on that behaviour.

0272404f73 Handle situations where we've already got a P2P interface address 
of a/x -> b and then negotiate a/x -> c by simply expecting SIOCAIFADDR
to do the change.

This was broken by the last commit that optimised out the deletion and
re-addition of the same a/x -> b combination, and forgot to compare
the old/new destination addresses.

Conveniently enough, this problem didn't effect setups where the
default route goes via the ppp link, and most other setups don't
care what the the destination address is actually set to.  It broke
test environments where ppp connects to the local machine rather
badly though....

da70ad6081 Handle IP over IP (IPPROTO_IPV4) properly. 
We now unwrap IP/IP and apply filter rules to both the outer
  layer (with ``set filter blah x.x.x.x y.y.y.y ipip'') and to
  the payload (reinterpreted by the filter rules).

  ``set log tcp/ip'' will now show both the outer wrapper and
  the (reinterpreted) payload contents.

16004197c4 If we're adding an interface address that is already one of the interface's 
aliases with the same netmask and destination, don't remove it and then
re-add exactly the same thing.

This means that static (non-sticky) routes that use the interface address
(or destination address) as a destination will not suddenly evaporate when
IPCP comes up (not unless the negotiated IPs have changed anyway).

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.

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 
cumulative total of all active links rather than basing it on the
total of PROTO_MP traffic.

This fixes a problem whereby Cisco routers send PROTO_IP packets only
when there's only one link (hmm, what a good idea!).

0a4b6c5c5c Allow a ``timeout secs'' filter option to let specific packet types 
effect the idle timer in different ways.

Submitted by: Stefan Esser <se@freebsd.org>

With adjustments by me to document the option in the man page and to
give the same semantics for outgoing traffic as incoming.

I made the style more consistent in ip.c - this should really have
been done as a separate commit.

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.
