Hello:

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

On Sun,  2 May 2021 22:34:42 +0100 you wrote:
Check at start of fill_frame_info that the MAC header in the supplied
skb is large enough to fit a struct hsr_ethhdr, as otherwise this is
not a valid HSR frame. If it is too small, return an error which will
then cause the callers to clean up the skb. Fixes a KMSAN-found
uninit-value bug reported by syzbot at:
