Yes, I agree with Alfred that we can turn VIMAGE back off before
11-RELEASE if things don't get cleaned up.
We have approximately until the end of 2015, so that gives

Again, I agree with Alfred on this. Darren Reed originally imported
ipfilter into FreeBSD, but hasn't actively maintained it (in FreeBSD) in a
while. Cy Schubert has recently expressed interest in ipfilter and has
committed some fixes in the past year, but has not fixed the VIMAGE problems
( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=176992 ).
I can take an initial effort at trying to fix VIMAGE + ipfilter.
In the past, I've delved into areas I'm not so familiar with in
order to fix VIMAGE + Bluetooth. If Cy can provide any knowledge or
guidance, that will be great.
A lot of bug fixes have gone into VIMAGE in the past 2 years,
and I have received multiple reports of people using it in production
environments. See the latest post by Peter Ross.
To flush out the last few issues and corner cases, I think we
need to turn VIMAGE on by default and get feedback and help from
the FreeBSD user community and developers to identify and fix the problems.
We have about 1 year until 11-RELEASE, so I think it is OK to do this.
I would also add two items to my action plan.
(6) Ask clusteradm to run one of the machines they use
for PF firewalls + IPv6 with a VIMAGE enabled kernel, and provide
(7) Ask for help with testing from companies who have more involvement
with the network stack. Two of the people in the CC: line of this
e-mail work for such places. :)
