d487445d05 Handle IP over IP (IPPROTO_IPV4) properly.
We now unwrap IP/IP and apply filter rules to both the outer
  layer (with ``set filter blah x.x.x.x y.y.y.y ipip'') and to
  the payload (reinterpreted by the filter rules).

  ``set log tcp/ip'' will now show both the outer wrapper and
  the (reinterpreted) payload contents.

7bc7c104ee Allow a ``timeout secs'' filter option to let specific packet types
effect the idle timer in different ways.

Submitted by: Stefan Esser <se@freebsd.org>

With adjustments by me to document the option in the man page and to
give the same semantics for outgoing traffic as incoming.

I made the style more consistent in ip.c - this should really have
been done as a separate commit.

c91d3bd70a o Overhaul filtering, adding facilities to jump over rules and to
negate the sense of rules.
o Remove the redundant (and undocumented) ``host'' and ``port''
  words (README.changes updated).
o Don't permit (and ignore) garbage instead of the protocol.

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 :-(

a7f001c816 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).

486b8925ec Cosmetic (no functional changes):
o   Add missing $Id$s
o   Move extern decls from .c -> .h files
o   Staticize
o   Remove #includes from .h files
o   style(9)ify includes
o   bcopy -> memcpy
    bzero -> memset
    bcmp -> memcmp
    index -> strchr
    rindex -> strrchr
o   Move timeout.h -> timer.h (making it consistent w/ timer.c)
o   Add -Wmissing-prototypes

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.

808a36ef65 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.

   o Add new parameter that re-sent interval for set timeout commands.
   o Improving RTT (Round Trip Time) and reducing processor time.
