3b0f8d2ed6 o Move struct lcp and struct ccp into struct link.
o Remove bundle2lcp(), bundle2ccp() and bundle2link().
  They're too resource-hungry and we have `owner pointers'
  to do their job.
o Make our FSM understand LCPs that are always ST_OPENED
  (with a minimum code that != 1).
o Send FSM code rejects for invalid codes.
o Make our bundle fsm_parent deal with multiple links.
o Make timer diagnostics pretty and allow access via ~t
  in `term' mode (not just when logging debug) and
  `show timers'.  Only show timers every second in debug
  mode, otherwise we get too many diagnostics to be useful
  (we probably still do).  Also, don't restrict ~m in term
  mode to depend on debug logging.
o Rationalise our bundles' phases.
o Create struct mp (multilink protocol).  This is both an
  NCP and a type of struct link.  It feeds off other NCPs
  for output, passing fragmented packets into the queues
  of available datalinks.  It also gets PROTO_MP input,
  reassembles the fragments into ppp frames, and passes
  them back to the HDLC layer that the fragments were passed
  from.
  ** It's not yet possible to enter multilink mode :-( **
o Add `set weight' (requires context) for deciding on a links
  weighting in multilink mode.  Weighting is simplistic (and
  probably badly implemented) for now.
o Remove the function pointers in struct link.  They ended up
  only applying to physical links.
o Configure our tun device with an MTU equal to the MRU from
  struct mp's LCP and a speed equal to the sum of our link
  speeds.
o `show {lcp,ccp,proto}' and `set deflate' now have optional
  context and use ChooseLink() to decide on which `struct link'
  to use.  This allows behaviour as before when in non-multilink
  mode, and allows access to the MP logical link in multilink
  mode.
o Ignore reconnect and redial values when in -direct mode and
  when cleaning up.  Always redial when in -ddial or -dedicated
  mode (unless cleaning up).
o Tell our links to `staydown' when we close them due to a signal.
o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without
  alarms).
o Don't bother strdup()ing our physical link name.
o Various other cosmetic changes.

75b8d2834b Handle sig 1, 2, 3 and 15 when we're the parent in background mode
by sending a SIGINT to the child.  This was intended before, but
pending_signal() was wrongly used - resulting in no action being
taken as the parent will never enter the main processing loop.

398381d7d2 Honour the reconnect command when the link is closed due
to the lack of an LQR response.  After all, the link is
being dropped due to something beyond our control.

1e991daad5 Remove some more globals:
o int modem was unused.
  o StateNames[] is now accessed via State2Nam()
  o ipKeepAlive is no more.  As a result, we must call FilterCheck()
    twice if we're doing TCP/IP logging (once when we queue and log
    the packet and once when we transmit it and need to know if the
    idle timer should be reset), but this won't be the case
    in normal life.

2267893f11 o Check the LCP Identifier field for correctness and drop
dodgy packets by default.

  we build our LCP/CCP/IPCP requests.
o Don't assume sizeof(u_long) == 4.

879ed6fa82 De-staticise LQR information
Increment OutPackets for any packet - not just LQRs

MFC:
  o Fix a few comment typos.
  o Fix ``set timeout'' usage message and documentation.
  o Change ifOutPackets, ifOutOctets and ifOutLQRs to `u_int32_t's
    so that they wrap correctly.
  o Put the LQR in network byte order using the correct struct size
    (sizeof u_int32_t, not sizeof u_long).
  o Wrap LQR ECHO counters correctly.
  o Don't increment OutLQR count if the last LQR hasn't been replied
    to.
  o Initialise last received LQR in StartLqm.
  o Don't start the LQR timer if we're `disabled' and `accepted'.
  o Generate LQR responses when both sides are using a timer and
    we're not going to send our next LQR before the peers max timeout.

6d6667755e Create struct fsm_parent. FSMs are created with one of these,

6eddf53ee8 Move our Layer*() FSM callbacks into their own structure. 1998-02-24 03:36:50 +00:00
Brian Somers
f4768038f0 o Remove the global CcpInfo. It's now part of the datalink.
Struct bundle will have its own struct ccp in the future
  too.
o The ``set stopped'' command now requires context and doesn't
  work on the IPCP FSM.
o Check if it's time to break out of our top level loop before
  doing a select - otherwise, we'll select forever :-(
o Remove `struct link'::ccp (a temporary hack).  It turns out
  that IpStartOutput() calls link_Output() and link_Output()
  incorrectly calls StartOutput() (really modem_StartOutput)
  requiring the ccp knowledge so that it can call
  IpStartOutput()...  The end result is that the whole IP
  output queue gets dumped into the modem output queue
  and a pile of physical writes are done prematurely.  This
  makes the (original) code in main() actually work in that
  it would not bother selecting() on the tun descriptor when
  our modem queue length was 20 or greater.  Instead, we now
  make that decision based on the overall queue length.

  This will need improvement later.
