Description David Woodhouse 2008-05-22 13:52:21 UTC 
Someone told me IP{V6,}_ADD_MEMBERSHIP sockopts were deprecated and we should
use MCAST_JOIN_GROUP instead. That fails for 32-bit userspace on 64-bit kernels,
though. Fixed by upstream commit dae50295.

Test case at http://david.woodhou.se/MulticastTest.c should print '5 bytes
received' but will just hang.

Note that on RHEL4 you seem to have to have a global IPv6 address in order for
the test to work; I think that might be a separate bug.
