Hello, Please picked up this patch for linux 4.4 and 4.9. Compiled/tested without problem. Thank. [ Upstream commit 4dc69c1c1fff2f587f8e737e70b4a4e7565a5c94 ] From: Kees Cook <keescook@xxxxxxxxxxxx> Date: Fri, 5 May 2017 15:30:23 -0700 Subject: [PATCH] bna: ethtool: Avoid reading past end of buffer Using memcpy() from a string that is shorter than the length copied means the destination buffer is being filled with arbitrary data from the kernel rodata segment. Instead, use strncpy() which will fill the trailing bytes with zeros. This was found with the future CONFIG_FORTIFY_SOURCE feature.

Queued for 4.9 and 4.4, thank you. -- Thanks, Sasha
