SVN rev 199526 on 2009-11-19 13:30:06Z by bms
Adapt r197132 to IPv6 stack:
Tighten input checking in in6p_join_group():
* Don't try to use the source address, when its family is unspecified.
* If we get a join without a source, on an existing inclusive
mode group, this is an error, as it would change the filter mode.
Fix a problem with the handling of in6_mfilter for new memberships:
* Do not rely on im6f being NULL; it is explicitly initialized to a
non-NULL pointer when constructing a membership.
* Explicitly initialize *im6f to EX mode when the source address
is unspecified.
This fixes a problem with in_mfilter slot recycling in the join path.
