Re: [PATCH] ethernet/netronome/nfp: Fix a use after free in nfp_bpf_ctrl_msg_rx

Hello:

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

On Mon, 29 Mar 2021 04:50:02 -0700 you wrote:
In nfp_bpf_ctrl_msg_rx, if
nfp_ccm_get_type(skb) == NFP_CCM_TYPE_BPF_BPF_EVENT is true, the skb
will be freed. But the skb is still used by nfp_ccm_rx(&bpf->ccm, skb).

My patch adds a return when the skb was freed.

Fixes: bcf0cafab44fd ("nfp: split out common control message handling code")
