Eric Dumazet 1b91c597b0 ipv6: mcast: add RCU protection to mld_newpack() ...

[ Upstream commit a527750d87 ]

mld_newpack() can be called without RTNL or RCU being held.

Note that we no longer can use sock_alloc_send_skb() because
ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep.

Instead use alloc_skb() and charge the net->ipv6.igmp_sk
socket under RCU protection.

Fixes: b8ad0cbc58 ("[NETNS][IPV6] mcast - handle several network namespace")
