[Impact]
Memory leaks when processing some packets may lead to out-of-memory
situations.

[Test case]
Memory leak was observed with a test case on a kernel without the fix.
It could not be observed once the fix was applied.

[Potential regression]
Processing of IGMPv6 packets may be affected.

Eric Dumazet (1):
  ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()
