6ca7707b44 When a netgraph message is read, look for another before returning.
This removes a bad latency problem during initial setup where we
end up waiting for too long before reading the connected message
and time the connection out.

de59e178aa o Clean up some #includes
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.

  When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
  to the SESSIONID from the environment in direct mode or the
  NGM_PPPOE_SESSIONID message in other modes.  If no SESSIONID is found,
  default to the interface index in client mode or zero in server mode.

  When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
  of the physical device (ie, the N in /dev/i4brbchN).

  This makes it easier for the RADIUS server to identify the client
  WRT accounting data etc.

fb11a9c23d Merge the NETGRAPH branch into HEAD. tty devices now use netgraph's line
discipline to do the async escaping, but no other benefits are available yet.

Change ``ifdef HAVE_DES'' to ``ifndef NODES'' for consistency.

Make the Makefile a little more sane WRT RELEASE_CRUNCH.

30949fd4b5 o Add ipv6 support, abstracting most NCP addresses into opaque
structures (well, they're treated as opaque).

  It's now possible to manage IPv6 interface addresses and routing
  table entries and to filter IPV6 traffic whether encapsulated or
  not.

  IPV6CP support is crude for now, and hasn't been tested against
  any other implementations.

  RADIUS and IPv6 are independent of eachother for now.

  ppp.linkup/ppp.linkdown aren't currently used by IPV6CP

o Understand all protocols(5) in filter rules rather than only a select
  few.

o Allow a mask specification for the ``delete'' command.  It's now
  possible to specifically delete one of two conflicting routes.

o When creating and deleting proxy arp entries, do it for all IPv4
  interface addresses rather than doing it just for the ``current''
  peer address.

o When iface-alias isn't in effect, don't blow away manually (via ``iface
  add'') added interface addresses.

o When listening on a tcp server (diagnostic) socket, bind so that a
  tcp46 socket is created -- allowing both IPv4 and IPv6 connections.

o When displaying ICMP traffic, don't display the icmp type twice.
  When display traffic, display at least some information about unrecognised
  traffic.

o Bump version

c8b9fb53a1 Handle hardware-imposed MTU/MRU limitations. PPPoE will no longer
allow MRU/MTU negotiations to exceed 1492.

Add an optional ``max'' specifier to ``set m[rt]u'', ie.

	set mtu max 1480

Bump the ppp version number.

2cb305af77 Rewrite the link descriptor transfer code in MP mode.
Previously, ppp attempted to bind() to a local domain tcp socket
based on the peer authname & enddisc.  If it succeeded, it listen()ed
and became MP server.  If it failed, it connect()ed and became MP
client.  The server then select()ed on the descriptor, accept()ed
it and wrote its pid to it then read the link data & link file descriptor,
and finally sent an ack (``!'').  The client would read() the server
pid, transfer the link lock to that pid, send the link data & descriptor
and read the ack.  It would then close the descriptor and clean up.

There was a race between the bind() and listen() where someone could
attempt to connect() and fail.

This change removes the race.  Now ppp makes the RCVBUF big enough on a
socket descriptor and attempts to bind() to a local domain *udp* socket
(same name as before).  If it succeeds, it becomes MP server.  If it
fails, it sets the SNDBUF and connect()s, becoming MP client.  The server
select()s on the descriptor and recvmsg()s the message, insisting on at
least two descriptors (plus the link data).  It uses the second descriptor
to write() its pid then read()s an ack (``!'').  The client creates a
socketpair() and sendmsg()s the link data, link descriptor and one of
the socketpair descriptors.  It then read()s the server pid from the
other socketpair descriptor, transfers any locks and write()s an ack.

Now, there can be no race, and a connect() failure indicates a stale
socket file.

This also fixes MP ppp over ethernet, where the struct msghdr was being
misconstructed when transferring the control socket descriptor.

Also, if we fail to send the link, don't hang around in a ``session
owner'' state, just do the setsid() and fork() if it's required to
disown a tty.
