From 339de30f5b40b08574a8ca53670d795f7dd1f8bb Mon Sep 17 00:00:00 2001 From: Mark Rustad Date: Fri, 6 Jun 2014 01:57:06 +0000 Subject: [PATCH] ixgbe: Change some uses of strncpy to strlcpy Change some uses of strncpy to use the more appropriate strlcpy when clearing is not needed to prevent information leakage. Also change some length arguments to use the preferred sizeof form.
