From: Calvin Owens <calvinowens@xxxxxx> ip_vs_prepare_tunneled_skb() ignores ->sk when allocating a new skb, either unconditionally setting ->sk to NULL or allowing the uninitialized ->sk from a newly allocated skb to leak through to the caller. This patch properly copies ->sk and increments its reference count.
