that ppp stays in the foreground.
o Add the -quiet switch to quieten ppps startup
o Add the -nat flag and discourage the use of the -alias flag. Both do
the same thing.
o Correct some nat usage strings.
o Change the internal ``alias'' command to ``nat''.

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).

get confused if you accept their endpoint discriminator but reject
their MRRU.

having different speed links in a bundle. This would manifest itself
by having the link occasionally hang, but revive when a new connection
is made....
Make ``show mp'' a bit prettier.

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().

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''.

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 :-(

o The others may be set in PHASE_ESTABLISH as long as no links
have yet reached DATALINK_LCP.

This should fix problems where ``ppp -auto'' seems to stop
responding after failing to connect to the peer a few times.

(see the new ``set callback'' and ``set cbcp'' commands)
o Add a ``cbcp'' log level and mbuf type.
o Don't dump core when \T is given in ``set login'' or
``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 Fix a few man page inconsistencies.

o If we've denied and disabled all compression protocols, stay
in ST_INITIAL and do an LCP protocol reject if we receive any
CCP packets.
o If we've disabled all compression protocols, go to ST_STOPPED
and wait for the other side to ask for something.
o If we've got anything enabled, start REQing as soon as the auth
layer is up.
o If we're in multilink mode, than the link level CCP goes
straight to ST_STOPPED irrespective of what's configured so that
we never try to compress compressed stuff by default.

end up writing zero bytes, sleep for 1/10 of a second so that
we don't end up using up too much cpu.
This should only ever happen on systems that wrongly report a
descriptor as writable despite the tty buffer being full.
Discussed with: Jeff Evarts
o Do an initial run-time check to see if select() alters the passed
timeval. This knowledge isn't yet used, but will be soon.

o Bring the static ``ttystate'' into struct prompt so that
the tilde context is per prompt and not global.
o Comment the remaining static variables so that it's
clear why they're static.
o Add some XXX comments suggesting that our interface list
and our hostname should be re-generated after a signal
(say SIGUSR1) so that a machine with PCCARDs has a chance.

transferring session rights with them. Instead, create two
`/bin/cat' processes. A new child is spawned and disassociated from
the terminal and the parent, which continues with the rest of the ppp
process. Meanwhile, the parent spawns another child, and both the
parent and child exec the `/bin/cat' commands with the appropriate
descriptors. This way, the session is owned by the parent, and the
tty is held open.
o Close LCPs that have done a TLF and are now in ST_STOPPED before
calling Down. This prevents them from trying to come back up again
after the peer has shut them down (it seems a bit strange that the
rfc says that a Down in ST_STOPPED will cause a TLS etc).
o Don't try to set the physical link name pointer when we're receiving
and renaming a datalink. The physical hasn't been created yet, and as
it happens, the garbage physical pointer happens to be the value of another
physical - so we're pointing that other physical name at ourselves.
yeuck.
o Re-arrange the order of things in main (DoLoop()). We now handle
signals only after the select and not before the UpdateSet. It's
possible that either a signal (FSM timeout) or a descriptor_Read()
brings a link down, after which we'd better tidy up any dead direct
and 1off descriptors before calling UpdateSet() again.
o Mention when we detect a PPP packet when we see one before the link
is up (then start LCP as before).

It's now dealt with by the `server' object. This simplifies
things as we only have one list of prompt descriptors and
the log_ routines check prompt::logactive to determine
whether it should be used for output.
o Include the MP socket UpdateSet() result in bundle::UpdateSet().
o Don't select on the tun device unless we're in NETWORK
phase or AUTO mode.
o Stop the idle timer when we go to DEAD phase. We may
have transferred a link and not had a chance to kill
it.
o Don't fail when trying to unlink our transferred datalink
from our descriptor lists just before the transfer.
o Add our link descriptor to the write set if we got a short
write the last time (physical::out is set).
o Log the connection source address when a connection is closed.
o Remove descriptor::next field. Descriptor lists are not required
any more.

o Understand sequence number wrapping when determining the minimum
sequence number.
