Objected to by: Andre Oppermann <oppermann@pipeline.ch>
After Andre's objection, I've re-examined rfc 2759 and noted that it
says that the domain name shouldn't be used when generating the
NT-Response field. So it looks like the bug is in freeradius rather
than in ppp.
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.
RAD_MICROSOFT_MS_CHAP_ERROR and RAD_MICROSOFT_MS_CHAP2_SUCCESS
messages, and remove the hack in chap.c to ignore that ident field
on the client side.
This anomoly was hacked around during development, and I forgot to
go back and fix it properly.

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).

sufficient.
In fact, using both breaks the radiator RADIUS daemon when used with
a db as it maps both attributes to the same field value and then
fails the insert.
I decided to remove RAD_NAS_IP_ADDRESS on the basis that rfc2138 says:
An Access-Request MUST contain a User-Name attribute. It SHOULD
contain either a NAS-IP-Address attribute or NAS-Identifier
attribute (or both, although that is not recommended). It MUST
despite the fact that this not recommended bit was removed from the
updated rfc.

Handle internal failures in radius_Authenticate() correctly.
Bump the ppp version number.
This doesn't yet work with MPPE. More will follow.

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.

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

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.
Problem pointed out by: Eugene Vigovskiy <vigov@com2com.ru>
Allow ``set server open'' to re-open the diagnostic socket.
Handle SIGUSR1 by re-opening the diagnostic socket
When receiving SIGUSR2 (and in ``set server none''), don't forget the
socket details so that ``set server open'' and SIGUSR1 open it again.
Don't create the diagnostic socket as uid 0 ! It's far to dangerous.

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''.
This was pretty harmless as netmasks on a POINTOPOINT
interface are pretty much ignored, but it looked funny.
Mention the configured netmask in ``show ipcp''.

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!).

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.

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 :-(
