3377c28cd9 Deal with the fact that as we now mbuf_Read the fsm
header in fsm_Input() we often end up with a NULL mbuf.

Deal with a possible NULL mbuf being passed into
mbuf_Prepend().

Adjust some spacing to make things more consistent.

5d9e610366 o Redesign the layering mechanism and make the aliasing code part of
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''.

b7c5748e5e o Rename datalinks as soon as the name has been received so that
LQM and HDLC timer diagnostics come out with the correct name.
o Don't send an LQR immediately upon reviving a datalink.  Leave
  it 'till the next timeout.
o Add the link name to some more LQR diagnostics.
o Break out of the main loop when a descriptor exception is seen
  in select().
o Remove the evil nointr_[u]sleep() functions.  Timers should be
  (and are) used instead.
o Treat a read() of 0 bytes as an error that's fatal to the link
  on which the read() is done.  We should never read() 0 after
  select() says there's something there - not unless the link
  has been closed by the other side.
o Write the data seen before a HDLC header to the terminal in
  `term' mode, *not* back to the modem :-/
o Initialise our transmitted file descriptor before starting any
  timers.
o Only send data links that have *no* pending output data.  This
  means that our final ACK will be written rather than being
  nuked with the datalink transmission.

643f49047e o Defer setting up pap/chap based IP numbers & labels until after
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.

2764b86afd o Move alias function pointers into loadalias.c
o Move Var*Version into command.c
o Remove struct pppVars (and there was much rejoicing) !
o Forward-decl some structs in .h files to avoid include
  ordering requirements and remove a few more redundant
  #includes.

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.

b6e82f33ef Fix prototypes.
Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.

We can now survive a compile with
  -Wall -Wbad-function-cast -Wcast-align -Wcast-qual
  -Winline -Wmissing-declarations -Wmissing-prototypes
  -Wnested-externs -Wpointer-arith -Wredundant-decls
  -Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).

927145be97 Overhaul ppp:
o Use syslog
  o Remove references to stdout/stderr (incl perror())
  o Introduce VarTerm - the interactive terminal or zero
  o Allow "set timeout" to affect current session
  o Change "set debug" to "set log"
  o Allow "set log [+|-]flag"
  o Make MSEXT and PASSWDAUTH stuff the default
  o Move all #ifdef DEBUG stuff into the code - this
    shouldn't be too much overhead.  It's now controlled
    with "set log +debug"
  o Add "set log command, debug, tun, warn, error, alert"
  o Remove cdefs.h, and assume an ansi compiler.
  o Improve all diagnostic output
  o Don't trap SIGSEGV
  o SIGHUP now terminates again (log files are controlled
    by syslog)
  o Call CloseModem() when changing devices
  o Fix parsing of third arg of "delete"

I think this fixes the "magic is same" problems that some
people have been experiencing.
The man page is being rewritten.  It'll follow soon.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

76bd0c0a9d Some patches to ppp which improve stability. I have been running a
ppp based on these patches for about 3 weeks with no downtime.

The original submitters comments:

Two features iijppp has over kernel ppp that I like are predictor1
compression and demand dialing.  Here are a few bug fixes.

I expanded the priority queueing scheme and discovered it was broken
due to the assignment at ip.c line 300.  All packets were being
queued at the same priority.

Fixing priority queueing broke predictor1 compression.  Packets
were compressed before being queued and predictor1 worked as long
as the packets were popped off the queue in the same order they
were pushed onto the queue.

There were a few byte order problems in IP header tests also.

There is a recursion problem in SendLqrReport().  LcpClose() is
called when "Too many echo packets are lost" which winds up in
SendLqrReport() again.  I believe the original intention was to
just stop the LQR timer with the call to StopLqr() but the side
effects hurt.

53c9f6c0c4 New user Process PPP based on iij-ppp0.94beta2.
o Supporting SYNC SIO device (But need a device driver)
     - add "set speed sync"
   o Fixing bug for Predictor-1 function.
   o Add new parameter that re-sent interval for set timeout commands.
   o Improving RTT (Round Trip Time) and reducing processor time.
     - Previous Timer service was using polling, and now using
       SIGALRM ;-)
     - A 0.94beta2 will not work correctly....

   -- Follows are additinal feature not including 0.94beta2
   o Support Proxy ARP
     - add "enable/disable proxy" commands
   o Marging common routine in CHAP/PAP.
   o Enhancing LCP/IPCP log information.
   o Support local Authfication connection on port 300x and tty.
     - You can set up pair of your "hostname -s" and
       password in ppp.secret. if either ppp.secret file nor
       your hostname line don't exist, It will notify a message
       and working as same as previous version.(Backword compatibility)
     - If you did set up them, It's allow connection but nothing to do
       except help and passwd command.
     - add "passwd yourpasswd" commands
   o Support afilter - keep Alive filter that a packet can send/receiving
     according to ifilter/ofilter but doesn't count it as preventing idle
     timer expires.
     - Same syntax of other filters.
   o Fixing bugs reported by current user for previous one. Thanks !!
