50179a5819 Compensate for dodgy Win98/WinME MSCHAPv2 responses later in the code
path... after we've talked to any RADIUS servers involved, so that we
haven't touched the data before it gets to the server.

Make it clearer in the code that this compensation is done by setting
a flag to a value of zero, a flag which rfc2759 says *MUST* be zero.

While we're here, don't bother passing the peer challenge into
radius_Authenticate().  It's already part of the key we're passing in
(this becomes obvious now that I've structured that data...).

This ``fix'' doesn't help to authenticate Win98/WinME users in my test
environment as ports/net/freeradius seems to ignore the flag
completely anyway, but it may help with other RADIUS servers.

64df596967 Understand the following Microsoft Vendor Specific RADIUS attributes:
RAD_MICROSOFT_MS_MPPE_ENCRYPTION_POLICY
  RAD_MICROSOFT_MS_MPPE_ENCRYPTION_TYPES
  RAD_MICROSOFT_MS_MPPE_RECV_KEY
  RAD_MICROSOFT_MS_MPPE_SEND_KEY

These attributes may be supplied by a RADIUS server when MSCHAPv2 is
used to authenticate.

It *should* now be possible to build ppp with -DNODES and still support
CHAP/MSCHAP/MSCHAPv2/MPPE via a RADIUS server, but the code isn't yet
smart enough to do that (building with -DNODES just looses these
facilities).

6efbe1505f Handle MS-CHAPv2 authentication correctly via the RADIUS server (if it's
configured).
Handle internal failures in radius_Authenticate() correctly.
Bump the ppp version number.

This doesn't yet work with MPPE.  More will follow.

9e1dc5332d Don't assume challenges and responses don't contain embedded '\0's.
Mschapv2 response generation may produce embedded NULs... causing
us to send a bogus response to the radius server and end up
failing the client's valid response.

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!).

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 :-(
