bcc332bdb0 Allow random IP number allocation to peer.
Validate the peers suggested IP by attempting to make a routing table
entry.
Give up IPCP negotiation if the peer NAKs us with an unusable IP.
Always SIOCDIFADDR then SIOCAIFADDR when configuring the tun device.
Using SIOCSIFDSTADDR allows duplicate dst addresses (which we don't
want)!!!
Allow up to 200 interface names (was 50) (now that ppp can play server
properly).
Up the version number (1.5 -> 1.6).

Cosmetic:
  Log unexpected CCP packets in the CCP log rather than the ERROR log.
  Log unexpected Config Reqs in the appropriate LCP/IPCP/CCP log rather
  than the ERROR log.
  Log failed route additions and deletions with WARN, not TCPIP.
  Log the option id and length for unrecognised IPCP options.
  Change some .Sq to .Ar in the man page.

4bc84b8c11 Fix the CCP Type field value for DEFLATE.
(I *really* meant to do this  *before* committing the
deflate changes in the first place - oops).

Pppd is horribly broken in this respect - refer to the
ppp man page for details.  Ppp *WON'T* negotiate deflate
with pppd by default - you must ``enable'' and ``accept''
``pppd-deflate'' in your config.

While I'm in there, update the cftypes in ccp.c so that
we recognise some more protocols (we don't actually do
anything with them - just send a REJ).

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).

75240ed178 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

29a6597c6b o Initialize the PRED1 input queue when we
receive the ResetAck, NOT when we send the
   ResetReq (as per the rfc).
o  SILENTLY ignore CCPs that arrive *before*
   the network phase (as per the rfc).
o  Check that we've actually negotiated PRED1
   before sending PRED1 output.
   This bug has been around for a *VERY* long
   time !  We shouldn't need to explicitly disable
   PRED1 now :-)

944f709824 Make the code format more in line with style(9).

Update to version 1.1.

cb611434af Expand the "set stopped" command so that it can
idependently time out any of the FSMs.

Split LCP logging into LCP, IPCP and CCP logging,
and make room in "struct fsm" for the log level
that the state machine should use.

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.

6ed9fb2fc9 De-couple ppp from libalias. If libalias isn't there, the
alias commands simply won't work.  Only root may specify the
location of the alias lib (otherwise, it's hard-coded).

Make logprintf silently fail if LogOpen hasn't been called.

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.

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.

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

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 !!
