dcb79a71e6 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''.

424e32a4e7 o Alter the mbuf type as it's processed by different layers.
o Show more information about missing MP fragments in ``show mp''.
o Do away with mbuf_Log().  It was showing mbuf stats twice on
  receipt of LCP/CCP/IPCP packets.... ???!!?
o Pre-allocate a bit extra when creating LQR packets to avoid having
  to allocate another mbuf in mbuf_Prepend().

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''.

2f7b052d07 Split the recorded chap challenge into two - one for the
receiver and one for the sender.  This allows two simultaneous

doing on a daily basis myself until the existence of the
problem was

a truncated packet by the new authentication code :-(

5dc50d8ed5 When resending chap challenges, resend the same challenge
each time rather than making up a new one.

Increase the authname/authkey max sizes to 100 characters.

Allow ``authkey'' specifications beginning with ``!''.
When a challenge is received, the text following the
``!'' is executed as a program (expanding stuff in the same
way that ``sh'' and ``!bg'' do).  The program is passed the
peer name, peer challenge and local ``authname'' on standard
input and is expected to output the name/key combination that
should be used to build the CHAP response.

This provides support for Secure ID cards (guess what I was
given at work recently!) using CHAP.

Examples will follow.

4435d086fa Decouple pap & chap output routines from the corresponding
input routines and take advantage of the new init/continue
interface in libradius.  This allows a timely response on
other links in an MP setup while RADIUS requests are in
progress as well as the ability to handle other data from
the peer in parallel.  It should also make the future addition
of PAM support trivial.

While I'm in there, validate pap & chap header IDs if
``idcheck'' is enabled (the default) for other FSM packet
types.

NOTE: This involved integrating the generation of chap
      challenges and the validation of chap responses
      (and commenting what's going on in those routines).
      I currently have no way of testing ppps ability
      to respond to M$Chap CHALLENGEs correctly, so if
      someone could do the honours, it'd be much
      appreciated (it *looks* ok!).

e71381fcd9 o Send a CHAP challenge of 16 random digits when RADIUS is
configured.  This isn't strictly necessary according to the
  rfc, but it's suggested there....
o Don't forget to include our authname when sending a
  CHAP challenge when RADIUS is configured.
o Don't supply the ``16'' representing the chap answer
  length to radius_Authenticate() - libradius does this
  for us.
o When we successfully authenticate via radius_Authenticate(),
  continue with datalink_AuthOk() as expected.

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 :-(

  ``set hangup''.
o Allow ``*'' and blanks as placeholders in ppp.secret and
  allow a fifth field for specifying auth/cbcp dialback
  parameters.
o Remove a few extraneous #includes
o Define the default number of REQs (restart counter) in defs.h
  rather than hardcoding ``5'' all over the place.

o Allow ``set ....'' when we have multiple links but aren't in
  multilink mode.
o Do a TLS when we receive a ``Open'' event in ``Closed'' state,
  despite the rfc state transition table.  This is clearly an
  error in the RFC as TLS cannot have yet been called (without
  TLF) in the ``Closed'' state.
  I've posted a message to comp.protocols.ppp for confirmation.

suggesting PAP, be friendly and REQ PAP the next time.

555986da72 When responding to a CHAP challenge, don't try to use
ppp.secret to get a key value based on the peers name,
then send the value of AuthName with the encrypted result.
This is *way* too confusing.
Instead, always use AuthName and AuthKey as the documentation
says.

94d661ac8c Overhaul ppp:
o Use syslog
  o Remove references to stdout/stderr (incl perror())
  o Introduce VarTerm - the interactive terminal or zero
  o Allow "set timeout" to affect current session
  o Change "set debug" to "set log"
  o Allow "set log [+|-]flag"
  o Make MSEXT and PASSWDAUTH stuff the default
  o Move all #ifdef DEBUG stuff into the code - this
    shouldn't be too much overhead.  It's now controlled
    with "set log +debug"
  o Add "set log command, debug, tun, warn, error, alert"
  o Remove cdefs.h, and assume an ansi compiler.
  o Improve all diagnostic output
  o Don't trap SIGSEGV
  o SIGHUP now terminates again (log files are controlled
    by syslog)
  o Call CloseModem() when changing devices
  o Fix parsing of third arg of "delete"

I think this fixes the "magic is same" problems that some
people have been experiencing.
The man page is being rewritten.  It'll follow soon.
