It's now possible to put something like this in ppp.linkdown

Fixed some memory leakage with commands that expand words.
Made some functions static.
Fixed a diagnostic bug (iface add .... SIOCDIFADDR)
1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.
2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.
3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.
4) You can now send SCM_TIMESTAMP messages.
5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).
This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).
6) Fix userland programs to use CMSG_* macros too.
7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

and implement a far more subtle and correct fix.
The reason behind the infinite loop was that ppp was trying to make up
initial IPv6 numbers and wasn't giving up when it failed unexpectedly to
assign the addresses it just fabricated to it's interface (thinking that
the reason was because another interface was using the same address).
It now attempts this up to 100 times before just failing and trying to
muddle along (in reality, this should never happen more than a couple
of times unless our random number generator doesn't work).
Also, when IPv6 is not available, don't even try to assign the IPv6
interface address in the first place...

It's now possible to manage IPv6 interface addresses and routing

not.

any other implementations.
RADIUS and IPv6 are independent of eachother for now.

interface addresses rather than doing it just for the ``current''

o When iface-alias isn't in effect, don't blow away manually (via ``iface

o When listening on a tcp server (diagnostic) socket, bind so that a

of the two when calculating the MP throughput average for the ``set
autoload'' implementation.
This makes more sense as all links I know of are full-duplex. This
also means that people may need to adjust their autoload settings
as 100% bandwidth is now the theoretical maximum rather than 200%
(but of course, halfing the current settings is probably not the
correct answer either!).
This involves a ppp version bump as we need to pass an extra
throughput array through the MP local domain socket.

I made the style more consistent in ip.c - this should really have

o If the new ``filter-decapsulation'' is enabled, delve into UDP packets
that contain 0xff 0x03 as the first two bytes, and if we recognise it
as PROTO_IP, decapsulate it for the purpose of filter checking.
If we recognise it as PROTO_<anything else> mention this for logging
purposes only.
This change is aimed at people running PPPoUDP where the UDP traffic is
being sent over another PPP link. It's desireable to have the top level
link connected all the time, but to have the bottom level link capable
of decapsulating the traffic and comparing the payload against the filters,
thus allowing ``set filter dial ...'' to work in tunnelled environments.
The caveat here is that the top ppp cannot employ any compression layers
without making the data unreadable for the bottom ppp. ``disable deflate
pred1 vj'' and ``deny deflate pred1 vj'' is suggested.

When an NCP reaches TLF, *ONLY* datalink_Close() links that are
in DATALINK_OPEN.
When the last link reaches TLD, DOWN all NCPs (as we used to in the
links TLF (which was the wrong place anyway)), as the NCPs aren't
now going to datalink_Close() us unexpectedly, we get to continue
doing what we were told to do in the first place.
The result: When we lose a link, the IPCP layer goes down and
we actually call the stuff in ppp.linkdown !
don't bother to re-initialise the NCPs. Instead wait for
bundle_LinkClosed() to be called - IFF it actually is called.
By initialising the NCPs at this point, ppp was recursing
back into the fsm_Down() routing for the link, and losing
track of the reason that the link was being brought down.
The end result was that ``set reconnect'' would never do
anything.

method avoided all race conditions, but suffered from
sometimes running out of buffer space if enough clients
were piled up at the same time.
Now, the client pushes the link descriptor, one end of a
socketpair() and the ppp version via sendmsg() at the
server. The server replies with a pid. The client then
transfers any link lock with uu_lock_txfr() and writev()s
the actual link contents. The socketpair is now the only
place we need to have large socket buffers and the bind()ed
socket can keep the default 4k buffer while still handling
around 90 racing clients.
