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.
the `-literal' after the closing .Ed.
Where this happens, use ``.Bd -unfilled'' with ``.It Li'' to dodge
the problem - it looks better too.

(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.
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.
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''.
throughput measurement is enabled).
o Load balance the links based on weight *and* on a round-robin
basis. This makes things fairly even on an output basis. We
don't try to allow for the peer sending all his data down one
link (and try to send ours back up the other).
o Show the number of pending input buffers that can't be processed
in ``show mp''.
o Fix a typo in the man page.
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....
we've determined if we're going to join another ppp invocation.
o Make ``show link'' show all link details, and ``show links''
just give a list of links and their current status.
o Show our current label in ``show bundle''.
o Allow link cloning and removal as soon as our MRRU is set.
o Make ``show lcp'' require context as nothing will ever change
in our MP LCP (it's auto-configured as per rfc1990).
o Initialise our LQM owner in hdlc_Init().
o Store our endpoint discriminator and authentication name at both
the datalink and multilink level and compare them when we've
finished AUTHENTICATE phase and before entering NETWORK phase.
If they don't match, close the link again.
Display the information in the appropriate ``show'' command.
o Initialise datalink::phone and datalink::fsmp.object properly
when we're cloning the link.
o Show which link we're passing LQRs on in our diagnostics.
o Reject endpoint discriminator REQs at the logical multilink
level.
o Remove the rest of our CARRIER and LINK logging setup.
o change the default link name to ``deflink'' rather
than ``default''.
o Prepend the link name to CCP and LCP FSM diagnostics.
o Protect against 0 length options in CCP and IPCP REQ
interpreters (already done for LCP).
o Allow optional context for the `show' command.
o Use MPs link when interpreting commands if the multilink
mrru is configured rather than when multilink is active.
This means that once we've ``set mrru xxx'', we then need
to ``link deflink show ccp'' etc if we want to do link-level
stuff (based on the command requiring optional or manditory
context).
o Use the ifconfig'd interface address in `set enddisc {ip,mac}'
if it's there, otherwise the configuration file value.
multilink ('cos I've seen my ISP REQ it without multilink).
Setting MRRU is ifdef'd out until it's debugged and we can
merge -direct links with other running programs.
Fix MTU setting.
and denied by default (POLA).
o Remove ``enable'' msext. Now, doing a ``set nbns'' will
automatically enable a NBNS ACK/NAK rather than a REJ.
o Add accept|disable|deny|enable dns. If we ``accept'',
we'll tell the peer what our nameservers are (if he asks).
The values in resolv.conf can be overridden with the
``set dns'' command. If we ``enable'', we'll REQ using
our resolv.conf entries, and any NAKs are written back to
resolv.conf.
o Remove ``show msext'' and show the relevent IP numbers in
``show ipcp''.

o Parse a filter IP of ``0.0.0.0'' as having a width of 0,
not 32.
o Correct "set filter" usage message.
o Warn about bad filter names.
o Expand and correct a number of the man page sections.
bundle (non-negotiated vars) or to their respective IPCP,
LCP or CCP.
o Enable rolling throughput statistics by default.
o Remove the `display' command. These values now appear in
`show bundle', `show ipcp', `show ccp' and `show lcp'.
o Initialise auth name & key at bundle create time (oops).
o Rename pppd-deflate (the id-24 hack) to deflate24.
o Don't send both a REJ and a NAK to an IPCP or LCP REQ.
Favour the REJ (already done at the CCP level).
o Recurse in datalink_UpdateSet() when we change state, otherwise
we end up setting no descriptors and getting jammed in the
imminent select() instead of doing the dial/login/hangup.
o Display our CHAP encryption method despite being built with DES.
o Display VJ as not negotiated in ``show ipcp'' when necessary.
