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 :-(

anything for two mintues (see ``set choked'' and ``show
bundle''), nuke the ip, mp and link level buffer queues.
This should fix problems where ``ppp -auto'' seems to stop
responding after failing to connect to the peer a few times.
(see the new ``set callback'' and ``set cbcp'' commands)
o Add a ``cbcp'' log level and mbuf type.
o Don't dump core when \T is given in ``set login'' or
``set hangup''.
o Allow ``*'' and blanks as placeholders in ppp.secret and
allow a fifth field for specifying auth/cbcp dialback
parameters.
o Remove a few extraneous #includes
o Define the default number of REQs (restart counter) in defs.h
rather than hardcoding ``5'' all over the place.
o Fix a few man page inconsistencies.
o Allow ``set ....'' when we have multiple links but aren't in
multilink mode.
o Do a TLS when we receive a ``Open'' event in ``Closed'' state,
despite the rfc state transition table. This is clearly an
error in the RFC as TLS cannot have yet been called (without
TLF) in the ``Closed'' state.
I've posted a message to comp.protocols.ppp for confirmation.
o Bring the static ``ttystate'' into struct prompt so that
the tilde context is per prompt and not global.
o Comment the remaining static variables so that it's
clear why they're static.
o Add some XXX comments suggesting that our interface list
and our hostname should be re-generated after a signal
(say SIGUSR1) so that a machine with PCCARDs has a chance.

This change will allow a PPP host enabled with the "-alias" option to
run mrouted. This does not intend to forward the IGMP nor tunneled packets
to another host on the far side if the tun0 interface.
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).
allowing for a possible header on the front of all packets.
In OpenBSD, there's a structure containing the address
family here.
If we're building under OpenBSD, set up the ``flags'' part
of struct tuninfo (not there under FreeBSD) so that we config
the interface as POINTOPOINT.
Prefix prototypes with ``extern'' in os.c for consistency.
These changes are cosmetic under FreeBSD, but allow ppp to
build & work under OpenBSD (bar the srandomdev() stuff,
the inclusing of <net/if_var.h> and some Makefile symantecs).
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
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.
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.

of reconnect & -background.
o Fix reconnect anomolies.
o Make reconnect apply to failed LQR hangups (& mention in man page).
o Make reconnect effective in -background mode.
o Listen on socket in -background mode.
o Try all phone numbers in -background mode.
o Insist on system arg in -background mode.
o Make a control-connection close command exit in -background mode.
o Output status message to stdout on exit of parent in -background mode.
o Don't notify parent of success too soon.
o Describe termination EX_* code.
o Miscelaneous diagnostic corrections.
o Remove redundant connect_time from modem.c.
o Don't repeatedly DownConnection().
the connection after an unexpected loss of carrier:
set reconnect timer ntries
The man page warns against using this command when your
timeout value is slightly more than the other sides :{}

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.
(otherwise ppp's behavior remains unchanged) and documented by myself,
Steve Sims, Nate Williams, Martin Renters and god-only-knows who else. :-)

to keep the link up, so it re-dials whenever it detects the link go
down. This is useful for 'dedicated' links who use PPP.
It's been used for over a year w/out problems at different sites.
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

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.
