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.

not setting any timer. Instead, set a 1 millisecond timer.
This ensures that ppp will come out of it's select() call after
losing carrier in -ddial mode with a reconnect period of 0 and
going to ST_OPENING, rather than waiting indefinitely for some
other event to wake ppp up.
Bump the ppp version number to indicate the event.

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

This is necessary because MPPE will combine the protocol id with the
payload received on the tun interface, encrypt it, then prepend its

Previously, ppp attempted to bind() to a local domain tcp socket
based on the peer authname & enddisc. If it succeeded, it listen()ed
and became MP server. If it failed, it connect()ed and became MP
client. The server then select()ed on the descriptor, accept()ed
it and wrote its pid to it then read the link data & link file descriptor,
and finally sent an ack (``!''). The client would read() the server
pid, transfer the link lock to that pid, send the link data & descriptor
and read the ack. It would then close the descriptor and clean up.
There was a race between the bind() and listen() where someone could
attempt to connect() and fail.
This change removes the race. Now ppp makes the RCVBUF big enough on a
socket descriptor and attempts to bind() to a local domain *udp* socket
(same name as before). If it succeeds, it becomes MP server. If it
fails, it sets the SNDBUF and connect()s, becoming MP client. The server
select()s on the descriptor and recvmsg()s the message, insisting on at
least two descriptors (plus the link data). It uses the second descriptor
to write() its pid then read()s an ack (``!''). The client creates a
socketpair() and sendmsg()s the link data, link descriptor and one of
the socketpair descriptors. It then read()s the server pid from the
other socketpair descriptor, transfers any locks and write()s an ack.
Now, there can be no race, and a connect() failure indicates a stale
socket file.
This also fixes MP ppp over ethernet, where the struct msghdr was being
misconstructed when transferring the control socket descriptor.
Also, if we fail to send the link, don't hang around in a ``session
owner'' state, just do the setsid() and fork() if it's required to
disown a tty.

doing a HangupDone(). The HangupDone() may fuel
bundle_CleanDatalinks(), and if so, the bogus
UpdateSet() ends up select()ing on a closed
descriptor.....
Change the main `do/while' loop to a `for' loop so
that any `continue's do the bundle_CleanDatalinks()
& bundle_IsDead() bit.

0.81.1 of the i4b code - namely support of the I4B_VR_REQ
ioctl via the i4brbchX device.
Ppp controls the phone number, but idle timers and
SYNC/RAW decisions are still made by isdnd (in isdnd.rc).
This involves a new datalink state machine phase. The
``wait for carrier'' phase happens after dialing but
before logging in. The whole dial state should really
be abstracted so that each device type can deal with it
in its own way (thinking about PPPoE) - but that'll have
to wait.
The ``set cd'' symantics remain the same for tty devices,
but we now delay until we either get CD or timeout waiting
(at which time we drop the link if we require CD).
For i4b devices we always insist on carrier.
Thanks to hm@ for his help, and especially for pointing out
that I *don't* need to re-implement isdnd (that was a huge
waste of time !) :-]

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).

being the same as the previous (still supported) ``host:port''
syntax for tcp socket devices.
A udp device uses synchronous ppp rather than async, and avoids
the double-retransmit overhead that comes with ppp over tcp (it's
usually a bad idea to transport IP over a reliable transport that
itself is using an unreliable transport). PPP over UDP provides
througput of ** 1.5Mb per second ** with all compression disabled,
maxing out a PPro/200 when running ppp twice, back-to-back.
This proves that PPPoE is plausable in userland....
This change adds a few more handler functions to struct device and
allows derivations of struct device (which may contain their own
data etc) to pass themselves through the unix domain socket for MP.
** At last **, struct physical has lost all the tty crud !
iov2physical() is now smart enough to restore the correct stack of
layers so that MP servers will work again.
The version number has bumped as our MP link transfer contents have
changed (they now may contain a `struct device').
Don't extract the protocol twice in MP mode (resulting in protocol
rejects for every MP packet). This was broken with my original
layering changes.
Add ``Physical'' and ``Sync'' log levels for logging the relevent
raw packets and add protocol-tracking LogDEBUG stuff in various
LayerPush & LayerPull functions.
Assign our physical device name for incoming tcp connections by
calling getpeername().
Assign our physical device name for incoming udp connections from
the address retrieved by the first recvfrom().

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''.

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.

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.

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!).

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 :-(
