there's no resolv.conf.
Use a umask of 022 when creating resolv.conf, not 0644 !

You can now ``resolv restore'' in ppp.linkdown !
Add DNS0 and DNS1 macros.

ip_tos == IPTOS_LOWDELAY now get precidence over urgent
packets with ip_tos != IPTOS_LOWDELAY and non-urgent packets
with ip_tos == IPTOS_LOWDELAY.

packets as well as urgent TCP packets.

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''.

o Add the -quiet switch to quieten ppps startup
o Add the -nat flag and discourage the use of the -alias flag. Both do

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).

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''.

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.

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!).

When NAKing the peer, get as close as we can to what
he REQd.
When the peer NAKs us, get as close as we can to what
they NAKd with on our next REQ.

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 :-(

demand-dial links with dynamic IP numbers where the program
that causes the dial bind()s to an interface address that is
subsequently changed after ppp negotiation.
The problem is defeated by adding negotiated addresses to the
tun interface as additional alias addresses and providing a set
of ``iface'' commands for managing the interface. Libalias is
also required (and what a name clash!) - it happily IP-aliases
the address so that the source is that of the primary (negotiated)
interface and un-IP-aliases it on the way back.
An ``enable iface-alias'' is done implicitly by the -alias command
line switch. If -alias isn't given, iface-aliasing is disabled by
default and can't be enabled 'till an ``alias enable yes'' is done.
``alias enable no'' silently disables iface-alias.
So, for dynamic-IP-type-connections, running ``ppp -alias -auto blah''
will work for the first connection, although existing bindings will
not survive a disconnect/connect as the TCP peer will be trying to
send to the old IP address - the packets won't route.
It's now a lot easier to add IPXCP to ppp with minor updates to
the new iface.[ch] (if anyone ever gets 'round to it).
It's also now possible to manually add interface aliases with
something like ``iface add 1.2.3.4/24 5.6.7.8''. This allows
multi-homed ppp links :-)

(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 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.

It is now possible to change various link options and then
re-open the relevant layer, making the changes effective -
for example, switching off VJ compression or starting ECHO
LQRs on-the-fly.

for all datalinks in a bundle. Ppp now deals correctly
with link types that are changed while open
o When changing the type of the last AUTO link, only clear
the interface if we're not in PHASE_NETWORK. This allows
us to switch to -ddial mode while we have a connection
without suddenly unexpectedly throttling ourselves by
clearing the interface configuration.

in `set mode', `allow modes', on the command line and when
outputting mode names. The strings are matched so that only
enough characters to uniquely identify the string are required,
so you can now
ppp -a mylabel (for auto mode)
ppp -b mylabel (for background mode)
ppp -dd mylabel (for direct dial mode)
etc.
o Make -ddial dial when specified on the command line (oops).

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.
