263a0e79cc Add "set loopback on|off", defaulting to "on".
This tells ppp to loopback packets addressed to
the ppp interface IP coming *from* the tun
device.

This means that you can ping the tun interface IP
from inside :-)

48abae6115 Allow the use of a "stopped" timeout via the
"set stopped" directive.  If the timeout occurs
it will cause a "Down" event, hanging up the line
if it's still up.  This *isn't* part of the FSM
diagram, but I consider it ok as a "higher level
implementation specific timeout" as specified in
the rfc ;-}

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

52623b565c 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.

Here is also a patch for an improvement: In current imprementation,
even if PPP connection is disconnected by time out, prompt of
interactive mode does not change from "PPP>" to "ppp>" to
indicate the disconnection on a terminal.
So I modified the code to do that. (patch III)

324cb686d3 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

c3dd7bc8c4 1. Add a settable redial timer and logging of the process id in a file.
A settable redial timer helps to avoid the problem where both ends
   of a link want to dial at the same time and the line winds up busy
   for both ends. The process id is logged in /var/run/PPP.system where
   system is the name of the called system.  When both ends of a link
   are running in demand dial mode, you need an easy way to get the pid
   of the ppp on the called end so it can be killed and re-started with
   -direct or pppd started to handle the incoming ppp session.

2. Add secret description for "set timeout" to man.

77fb3e11a9 Fixing follows and John's fruent explnation than my English....
The first problem I found was that descriptor 0 was being closed.
This happens because the modem variable is set to 0 to indicate
that it is not valid but there are not enough tests for the modem
variable being 0.  You can see where I have done this in the patch.
Code in OpenModem() dups the modem descriptor if it is < 3.  Once
this happened the modem was always open and an incomming call would
have getty and ppp reading the modem.

Descriptor 1 is closed when the quit command was executed from a
telnet connection.  The next modem open returns descriptor 1
and this gets duped leaving the modem always open again.

The modem was not being closed when the connection dropped or was
closed from the other end.  The UUCP lock was also not removed if
the modem could not be opened.
