LABEL: The configuration label in use
PEER_ENDDISC: The peers endpoint discriminator
USER: The peers authname
anything for two mintues (see ``set choked'' and ``show
bundle''), nuke the ip, mp and link level buffer queues.
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.
``add .... HISADDR''. The network will never be
reachable at this point unless we're in -auto or reading
the command from ppp.linkup.
We can now run the following lines and get the expected
results:
set ifaddr 1.2.3.4/0 5.6.7.8/0
add default HISADDR
where a route is added immediately in auto mode and the
whole thing is delayed 'till the IP numbers have been
agreed in other modes.
Essentially, ppp.linkup is no longer required.
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.
open capable of re-negotiatiating the various layers.
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).

thresholds (in terms of queued packets for a period of time)
where -auto links will be brought up and down. By default,
all auto links come up when we reach NETWORK phase and never
go down.
o Display current autoload state in `show bundle'.
o Disable the idle timer as soon as it's called.
o Disable the idle and autoload timers when exiting (in case
we're abending).
is not possible to switch to or from dedicated or direct mode,
but all other combinations are ok (eg. -auto -> -ddial).
o Cope with the fact that commands with optional context may not
be able to obtain a link with command_ChooseLink() (if all links
have been deleted for example).
o Allow `clone'ing in non-multilink mode. We may for example want
to configure two links in unilink mode and dial them both, using
the one that comes up first. It's also possible to rename
``deflink'' by cloning it, deleting the original, then setting
the mode of the new link.
into the ST_STOPPED state.
o Allow an optional ccp|lcp argument to `down'. The default is
still lcp (as before). You can now call down with no context
in multilink mode, in which case it'll down the multilink ccp
or the entire bundle (*very* rude).
o Allow an optional `!' after `close ccp' (close ccp!) to tell
ccp to stay in the CLOSED state after the terminate ACK. The
default is now to re-enter STOPPED so that the peer can bring
the layer back up if desired.
o Always handle proto-compressed packets, even if we've agreed
(in LCP) that the peer will not send us 1 byte protocols.
If the peer violates the LCP agreement, log it to the HDLC
log.
o Fix some comments.
the first ``%d'' in the unix-domain socket name with the
current interface unit number. In the case of tcp ports, allow
a ``+'' prefix to add the unit number to the specified port
number.
o Remove all mention of SIGUSR1 (was already #ifdef'd out). We
can't create diagnostic sockets on-the-fly with a signal any
more because there's no way of specifying the password without
confusing matters with the previous ppp.secret scenario.
Any `add' or `delete' command that uses MYADDR or HISADDR
will be added to the sticky route list (show ipcp). When
MYADDR or HISADDR change due to IPCP negotiations, and if
`sroutes' is enabled (the default), all sticky route
entries are updated in the routing table.
The end result is that `add default hisaddr' will ``stick'',
as will ``add myaddr 255.255.255.255 127.0.0.1'' and
``add 1.2.3.4 255.255.255.0 hisaddr''.
exec()ing. Tidy up file dups in general prior to exec().
This prevents our tun device (fd 3) from staying open (and
configured) despite handing off all it's links and exiting
(because ``cat'' holds it open).
o Don't bother SIG_DFL'ing signals before exec() as they're
already trapped with specific handlers and will be handled
correctly by the exec.
o Use values from paths.h for "/dev/" and "/dev/tty".
o Don't assert() in physical.c.

o Use _PATH_DEVNULL rather than "/dev/null"
o Be more paranoid about nuking running timers when
transferring links.
log debug'' without filling our filesystem/screen with
junk that we don't really want to see.
o change PHYS_STDIN to PHYS_DIRECT - we can handle incoming
connections that aren't on STDIN_FILENO now.
o Allow return values from our FSM LayerUp functions. If
LayerUp() fails, the FSM does an immediate FsmDown() without
calling the fsm_parent's Layer{Up,Down} functions.
o Clear the close-on-exec flag of file descriptor 3 when executing
chat programs so that our documented ability to communicate with
/dev/tty via that descriptor works. Also document it as
descriptor 3, not 4 :-O
o Allow a ``rm'' command as an alias for ``remove''.
o Fix the bind()/connect()/accept() calls made by the MP server.
o Create bundle_SendDatalink() and bundle_ReceiveDatalink().
This allows `struct datalink's to flatten themselves, pass
through a pipe (read: the eye of a needle !) and come alive
at the other end. The donator then fork()s & exec()s pppmpipe,
``passing'' the connection to another ppp instance.
*** PPP NOW TALKS MULTILINK :-))) ***
Our link utilization is hideous, and lots of code needs
tidying still. It's also probably riddled with bugs !
It's been tested against itself only, and has hung once,
so confidence isn't high....
