Yes.
Multicast source filters aren't widely used yet, and that's
really the only feature that's affected if an application actually
exercises this bug, as far as I can tell. An ordinary filter-less
multicast join should still work, and only forwarded multicast
traffic making use of filters and doing empty-source filters with
the MSFILTER ioctl would be at risk of not getting multicast
traffic forwarded to them because the reports generated would not
be based on the correct counts.
But having the fix in is better than having it broken, even
for that case. :-)
