Hello, I am seeing a regression in the macvlan kernel driver after Linux stable release 4.4.209, bisecting identifies commit https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.4.y&id=8d28d7e88851b1081b05dc269a27df1c8a903f3e There seems to be a history behind this, and I do not have the full overview of the intention behind the change. What I see on my target, Aarch64 CPU, is that this patch moves the eth pointer in macvlan_broadcast() function some bytes. This will cause everything within the ethhdr struct to be wrong AFAICT. An example: Original code "eth = eth_hdr(skb)" eth = ffffffc007a1b002 New code "eth = skb_eth_hdr(skb)" eth = ffffffc007a1b010 Let me know if I can assist in any way. -- Best regards, Hans-Christian Noren Egtvedt
