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.
endian-ness fix, Router Alert options on IGMP messages, and a
new keyword, "advert_metric", for fine-tuning tunnel metrics.
This also includes a new mtrace, which is also unreleased but
builds significantly on the experiences of users' troubles with
using and understanding mtrace in release 3.8 .
(unreleased does not, of course, mean untested!)
This is a candidate for both 2.2 and 2.1.6 .
possibility of security holes allowing root penetration.

conflict markers, but it actually changes nothing.
We've been running this code with small changes for some time, this may
be useful for checking what those changes. It was unfortunate this
module got so far away from the vendor branch (whitespace changes didn't
help)
host sends a leave message for a group that the router is a member of
that membership gets forgotten until the next general query.
- the second group-specific query generated looks like a general query
sent to a specific group

mrouted-3.5n. This is being splatted onto the head rather than properly
imported thanks to the ``delete trailing whitespace'' screw. This code is
now actively working in an operational environment (the DARTNET) so I
have some confidence that the basic functionality actually works.

the fixes!):
o Scoped addresses might let traffic in
o IGMP queries sent with wrong timeouts
o Possible core dump in mtrace if we get a request for which we have no route
o If a member on a transit network left a group, mrouted would stop forwarding
even if there was a downstream router
o Various code cleanups and logging changes

in the mrouted. inet_parse returns network byte ordered address, but there
are a couple comaprisons that need to be done on the addresses and the
comparisons are done in host order. I left the comparisions for 0xffffffff
alone, because this value is the same in network and host orders.

submitting them as context diffs for the following files:
sys/netinet/ip_mroute.c
sys/netinet/ip_var.h
sys/netinet/raw_ip.c
usr.sbin/mrouted/igmp.c
usr.sbin/mrouted/prune.c
The routine rip_ip_input in raw_ip.c is suggested by Mark Tinguely
(tinguely@plains.nodak.edu). I have been running mrouted with these patches
for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.
