the bundle has the opportunity to go PHASE_DEAD and cleanup
the interface (if it's the last link).
o Regnerate our phys_type value when we transfer the link.
o Always clean up the interface when destroying our bundle in case
we're abending.
o Always clean up our interface when the last link is gone rather than
delaying things 'till exit time in the -direct case (the interface
is useless anyway). Do this *after* slamming down our NCPs (if
they're still around).
o Our MP server descriptor now clears the relevent device descriptor
from our descriptor [fd]sets when a datalink is on death-row (to
be transferred to another running ppp), thus avoiding the possibility
of passing a bum descriptor to select() and having ppp abend.
o Handle the MP socket descriptor functions from within the bundle
descriptor functions. Now we ensure that the MP socket descriptor
functions see the descriptor sets *after* they've been seen by our
datalinks.
o Add/fix a few more comments.
This program was originally written by Toshiharu OHNO <tony-o@iij.ad.jp>,
and was submitted to FreeBSD-2.0.5 by Atsushi Murai <amurai@spec.co.jp>.
The original version was usually referred to as iij-ppp.
Ppp is currently maintained under FreeBSD and OpenBSD by Brian Somers
<brian@Awfulhak.org>. The sources for both operating systems are the
same although the Makefiles vary due to the nature of each system.
If and when it's ported to another OS, things will probably be shuffled
around so that there are several Makefiles, one per architecture.
The latest sources are available in FreeBSD-current and OpenBSD-current.
An archive hacked so that it will build on just about any version of
FreeBSD is frequently generated and made available on
http://www.FreeBSD.org/~brian. Once the first OpenBSD release is made
with ppp, an up-to-date OpenBSD archive will be made available too.
A FAQ is available at http://www.FreeBSD.org/FAQ/userppp.html. It applies
equally to OpenBSD as it does to FreeBSD. The man page is quite extensive,
and there are lots of examples in /etc/ppp/ppp.*.sample. These examples
come with the hacked archive above but must be installed manually.
Ppp is still under development. There is no official TODO list.
