From a4ed2d4cd96dd71b0f2e04a88f83abcab6ddd023 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 2 Jul 2012 21:36:59 +0100 Subject: [PATCH] sfc: Use strlcpy() to copy ethtool stats names Fix CID 113703 in the Coverity report on Linux. ethtool stats names are limited to 32 bytes including a null terminator. Use strlcpy() to ensure that we will always include the null terminator even if a source string becomes longer than this.
