880447787d Add a radius_Flush() function that waits for the response (or timeout) to
any pending RADIUS transaction.  Use this before sending RAD_STOP RADIUS
messages so that we definitely ``stop'' the session.

It was discovered that sometimes when the link timed out, we got lucky
enough to have an un-ACK'd RADIUS accounting transaction in progress,
resulting in the RAD_STOP message failing to send.

e715b13bca Support a ``set rad_alive N'' command to enable periodic RADIUS accounting
information being sent to the RADIUS server.

Logging of RADIUS accounting information moves to a ``set log [+-]radius''
level, along with the RADIUS alive info, and the version number is bumped
to 3.2 to reflect this.

3c34956a21 If the peer gives us 0.0.0.0 as his IP number, NAK it rather than accepting
it as being in range.

  set ifaddr 1.2.3.4/0 5.6.7.8/0

no longer allows 0.0.0.0 as a valid IP.

ff360cc91b Make the way FSM options are processed easier to read by using structures
instead of u_char *.

The changes are cosmetic except:

  RecvConfigAck() now displays the options that are being ACK'd
  Huge (bogus) options sent from the peer won't cause an infinite loop
  SendIdent and ReceiveIdent are displayed consistenlty with other FSM data
  LCP AUTHPROTO options that aren't understood are NAK'd, not REJ'd

5ae083292b Specify the gateway address when updating the MTU and send/recv pipe
sizes on a route.

IMHO this shouldn't be necessary (the destination & mask/prefixlen
should be enough), but without it, the default route update under
OpenBSD will fail.

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

5e3b2d6847 If the peer sends a REQ without the IPADDR option, only reject it
once.  If they repeat the request (again without the IPADDR option)
ACK it.

I've had reports that some ppp implementations will not assign
themselves an IP number.  This should negotiate with such things.

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.

da47788649 Introduce a forth IP packet queue. Urgent packets with
ip_tos == IPTOS_LOWDELAY now get precidence over urgent
packets with ip_tos != IPTOS_LOWDELAY and non-urgent packets
with ip_tos == IPTOS_LOWDELAY.

Enhance the ``set urgent'' syntax to allow for urgent UDP
packets as well as urgent TCP packets.

442f849547 o Split the two IPCP queues into three - one for FSM data
(LCP/CCP/IPCP), one for urgent IP traffic and one for
  everything else.
o Add the ``set urgent'' command for adjusting the list of
  urgent port numbers.  The default urgent ports are 21, 22,
  23, 513, 514, 543 and 544 (Ports 80 and 81 have been
  removed from the default priority list).
o Increase the buffered packet threshold from 20 to 30.
o Report the number of packets in the IP output queue and the
  list of urgent ports under ``show ipcp''.

ab2de065b2 o Obsolete the undocumented ``set weight'' command.
o If we're using RADIUS and the RADIUS mtu is less than our
  peers mru/mrru, reduce our mtu to this value for NetBSD too.
o Make struct throughput's sample period dynamic and tweak the ppp
  version number to reflect the extra stuff being passed through
  the local domain socket as a result (MP mode).
o Measure the current throughput based on the number of samples actually
  taken rather than on the full sample period.
o Keep the throughput statisics persistent while being passed to
  another ppp invocation through the local domain socket.
o When showing throughput statistics after the timer has stopped, use
  the stopped time for overall calculations, not the current time.
  Also show the stopped time and how long the current throughput has
  been sampled for.
o Use time() consistently in throughput.c
o Tighten up the ``show bundle'' output.
o Introduce the ``set bandwidth'' command.
o Rewrite the ``set autoload'' command.  It now takes three arguments
  and works based on a rolling bundle throughput average compared against
  the theoretical bundle bandwidth over a given period (read: it's now
  functional).

5d9e610366 o Redesign the layering mechanism and make the aliasing code part of
the layering.

  We now ``stack'' layers as soon as we open the device (when we figure
  out what we're dealing with).  A static set of `dispatch' routines are
  also declared for dealing with incoming packets after they've been
  `pulled' up through the stacked layers.

  Physical devices are now assigned handlers based on the device type
  when they're opened.  For the moment there are three device types;
  ttys, execs and tcps.

o Increment version number to 2.2
o Make an entry in [uw]tmp for non-tty -direct invocations (after
  pap/chap authentication).
o Make throughput counters quad_t's
o Account for the absolute number of mbuf malloc()s and free()s in
  ``show mem''.
o ``show modem'' becomes ``show physical''.
