Re: [PATCH] net:tipc: Fix a double free in tipc_sk_mcast_rcv

Hello:

This patch was applied to netdev/net.git (refs/heads/master):

On Sun, 28 Mar 2021 00:30:29 -0700 you wrote:

In the if(skb_peek(arrvq) == skb) branch, it calls __skb_dequeue(arrvq) to get
the skb by skb = skb_peek(arrvq). Then __skb_dequeue() unlinks the skb from arrvq
and returns the skb which equals to skb_peek(arrvq). After __skb_dequeue(arrvq)
finished, the skb is freed by kfree_skb(__skb_dequeue(arrvq)) in the first time.

Unfortunately, the same skb is freed in the second time by kfree_skb(skb) after
the branch completed.
