8c9a4071f7 Implement an ``enable/disable echo'' option, defaults to off.
This allows LCP ECHOs to be enabled independently of LQR reports.

Note: This introduces a change in the default behaviour (search for lqr and
echo in the man page).  I'll update UPDATING to reflect this.

c2da7c8697 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.

b86a2d03f8 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

6a1de171ac Add a ``log'' command for logging specific information.
Add an ``UPTIME'' variable to indicate the bundle uptime.

It's now possible to put something like this in ppp.linkdown
for a server setup:

  MYADDR:
    log Session closing: User USER, address HISADDR, up UPTIME

Fixed some memory leakage with commands that expand words.
Made some functions static.

f9a9a183bf When the peer fails to specify an MRU and a 1500 byte MRU is not
allowed either because of the transport or configuration, send a
MRU NAK only once, then allow the negotiations to proceed.

rfc1661 says that 1500 should always be allowed and rfc2516 says
that 1492 is the maximum for PPPoE.  This changes ppp so that it
only weakly suggests 1492, then goes with the default (leaving
the problem in the hands of the peer WRT how they set their MTU).

de3feff3f8 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

635801f2ed If the peer REJects our MRU REQ, stop REQing it -- *EVEN* if we're
doing PPPoE and the default MRU is therefore too big.

When negotiating with win2k, we ask for MRU 1492 and the win2k box
NAKs us saying ``MRU 1492''.  This doesn't make sense to me.  When
we continue to request MRU 1492, the win2k box eventually REJs our
MRU.  This fix allows negotiations to continue at that point,
bringing the link up and potentially allowing the win2k box to send
us frames that are too large.  AFAICT this is better than failing
to bring the link up.... probably !

I have no idea how to do the equivalent of ``route get'' or
``ifconfig -a'' under win2k, so I can't tell what MTU it actually
ends up using.

I believe the bug is in win2k (it's certainly mis-negotiating).
I'll MFC given the release engineers permission as code freeze
begins on August 1.

ab7d88ae2d 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''.

e52674f2ac Revert the ACCMAP changes where we OR the peers accmap

ee13d15d8f Allow control over the number of ConfigREQ & TermREQ attempts
that are made in each of the FSMs (LCP, CCP & IPCP) and the
number of REQs/Challenges for PAP/CHAP by accepting more arguments
in the ``set {c,ip,l}cpretry'' and ``set {ch,p}apretry'' commands.

Change the non-convergence thresholds to 3 times the number of configured
REQ tries (rather than the previous fixed ``10'').  We now notice
repeated NAKs and REJs rather than just REQs.

Don't suggest that CHAP 0x05 isn't supported when it's not configured.

Fix some bugs that expose themselves with smaller numbers of retries:
o Handle instantaneous disconnects (set device /dev/null) correctly
  by stopping all fsm timers in fsm2initial.
o Don't forget to uu_unlock() devices that are files but are not
  ttys (set device /dev/zero).

Fix a *HORRENDOUS* bug in RFC1661 (already fixed for an Open event in state
``Closed''):
  According to the state transition table, a RCR+ or RCR- received in
  the ``Stopped'' state are supposed to InitRestartCounter, SendConfigReq
  and SendConfig{Ack,Nak}.  However, in ``Stopped'', we haven't yet
  done a TLS (or the last thing we did is a TLF).  We must therefore
  do the TLS at this point !

  This was never noticed before because LCP and CCP used not use
  LayerStart() for anything interesting, and IPCP tends to go into
  Stopped then get a Down because of an LCP RTR rather than getting a
  RCR again.

c970e06ccf Initial RADIUS support (using libradius). See the man page for
details.  Compiling with -DNORADIUS (the default for `release')
removes support.

TODO: The functionality in libradius::rad_send_request() needs
      to be supplied as a set of routines so that ppp doesn't
      have to wait indefinitely for the radius server(s).  Instead,
      we need to get a descriptor back, select() on the descriptor,
      and ask libradius to service it when necessary.
      For now, ppp blocks SIGALRM while in rad_send_request(), so
      it misses PAP/CHAP retries & timeouts if they occur.

      Only PAP is functional.  When CHAP is attempted, libradius
      complains that no User-Password has been specified... rfc2138
      says that it *mustn't* be used for CHAP :-(
