c06022153e Don't luse uu_lock in -direct mode. It conflicts w/
hylafax & the like.
Get the CD bit right at last - now that I've got
my second modem back - loss of carrier makes ppp exit.

35495bec8d Correct the way the uucp lock file and the ttyXX.if lock
file get created.  We don't create lock files over non-tty
connections, but we *do* create lock files in -direct mode.
This leaves us capable of adding utmp/wtmp support for
successful pap & chap logins (coming soon).

c47cab6191 It turns out that the following:
close(1);
  close(2);
  x = open(ctermid(NULL), O_RDWR|O_NONBLOCK);
  close(0)
on a tty causes select() to return an exception for descriptor x !
This is the case in RELENG_2_2, but not in 2.2.2.  I'm not sure why.
Instead of doing the x=open() and close(0), we just do x=0 now.

  o Zero VarTerm ASAP if not in interactive mode.

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.

99c02d39bc Fix many buffer overruns in the code. Specifically, disallow ExpandString
to be used to expand things beyond the size of the buffer passed in.  Also
do a general cleanup of sprintf -> snprintf as well as strcpy and strncat
safety.  Also expand some buffers to allow for the largest possible data
that might be used.

This is a 2.2 candidate.  However, it needs to be vetted on -current
since little testing has been done on this due to my lack of PPP on
this machine.

6d14e2a8e6 For /usr/sbin/ppp, you must choose between running ppp in the background or
connecting to a host immediately in the foreground.

I would like to be able to run ppp from a script so that my script can be
sure that it is connected to the 'net before it continues running:

  # Dial up the internet.
  ppp -background myprovider || exit 1

  do-some-net-command

  # Hang up the modem.
  kill -HUP `cat /var/run/ppp.tun0.pid`

Another problem is that the current ppp calls its process id file
`/var/run/PPP.server', which may conflict if you have more than one IP
tunnel interface available.

9c749ffb8b Here is a diff of /usr/src/usr.sbin/ppp against current. The diffs
add some logging functionality which I find very useful.
'set debug link' will record just link up/down and address assignments.
'set debug connect' will record the entire chat dialog
'set debug carrier' will record just chat lines including 'CARRIER'
(so that I can be sure I'm getting a 28.8 line).

There was a global change required to permit LogPrintf to take a bit
mask instead of a bit position value (to permit logging some events
on either of two flags, so that no change in 'set debug lcp' would
result from the code supporting 'link'.  Thus the diffs are rather
long for such a small change.  The man page is also touched.

Oh, and there was a slight syntax problem in route.c

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.
