7551d83c35 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

5f97c24afc Some 3G modems return the wrong signature in echo packets and make it
impossible to use LQR/ECHO. They return want_magic instead.

With this change it is now possible to use

	enable lqr
	set lqrperiod 5
	enable echo
	set echoperiod 5

in your ppp.conf file.

8c9a4071f7 Implement an ``enable/disable echo'' option, defaults to off.
This allows LCP ECHOs to be enabled independently of LQR reports.

Note: This introduces a change in the default behaviour (search for lqr and
echo in the man page).  I'll update UPDATING to reflect this.

c2da7c8697 o Clean up some #includes
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.

  When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
  to the SESSIONID from the environment in direct mode or the
  NGM_PPPOE_SESSIONID message in other modes.  If no SESSIONID is found,
  default to the interface index in client mode or zero in server mode.

  When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
  of the physical device (ie, the N in /dev/i4brbchN).

  This makes it easier for the RADIUS server to identify the client
  WRT accounting data etc.

dcb79a71e6 o Split the two IPCP queues into three - one for FSM data
(LCP/CCP/IPCP), one for urgent IP traffic and one for
  everything else.
o Add the ``set urgent'' command for adjusting the list of
  urgent port numbers.  The default urgent ports are 21, 22,
  23, 513, 514, 543 and 544 (Ports 80 and 81 have been
  removed from the default priority list).
o Increase the buffered packet threshold from 20 to 30.
o Report the number of packets in the IP output queue and the
  list of urgent ports under ``show ipcp''.

ab7d88ae2d 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''.

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 :-(

94d661ac8c 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.

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

9b03b51375 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.
