a66fe159a8 If we receive no answer from the server when sending PAP
requests, give up (don't sit there indefinitely).

c970e06ccf Initial RADIUS support (using libradius). See the man page for
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 :-(

963fbcd9be Recurse when we've switched state via LoginDone(). If we've
got an open link, we want it to be select()d on - otherwise
we get a freeze when ``openmode'' is passive.

db2579cb8b If we've configured CBCP *and* another not-so-important
CALLBACK protocol and end up agreeing CBCP, DTRT and go
into CBCP phase rather than mistakenly terminating as
if CBCP wasn't agreed.

d5964ebf5b Boy, this was tricky to find:
Remove any dial timer that might be hanging around at
  datalink_Destroy() time.  This timer may be left running
  after the link is closed (making sure it's not automatically
  opened again too soon).

00d5b6a213 When entering ``term'' mode, don't output any messages until
the device is successfully opened.  If we fail to open it,
mention the fact.
Also go back into command mode as soon as the device is closed
rather than waiting for the user to type something before noticing.

f9ee8808e7 o Support callback types NONE, E.164, AUTH and CBCP.
(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.

e15057ae7c Only start checking carrier when the datalink state machine
exceeds DATALINK_READY.  When we go back to READY or less
(eg. ``close lcp''), switch the carrier-checking-timer off again.

This fixes the callback example in ppp.conf.sample.

079249c72b The CCP layer now behaves as follows:
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.

1e23d0e92c Add `ipcp'' as an optional argument to `open'', and make
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.

7c567ca3f8 o If we come out of select() with only write descriptors that
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.

4ea5840027 Make `close lcp' just close the LCP layer and not hangup. This is
useful for slirp users that wish to get their shell back after the
ppp session.  `close' with no args still hangs up as expected.

0cb00afb55 o Maintain a link-type mask for open datalinks as well as
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.

36b1e9c4f0 o Make modes consistent throughout ppp. The same strings are used
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).

f0bbc1adc5 o Don't forget to close our transfer socket if we cannot
generate the data to transfer.
o Transfer uucp lock ownership for the transferred device.
o Don't assume we know the correct values of dev_is_modem and
  mbits after the transfer.

02218556c6 o Don't try to transfer tty device descriptors as there's no way of
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).

7f9f3d4b00 o Move our prompt descriptor list outside of the bundle.
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.
