From 286b63d09660de0fbd0d7748984d7ae491c7fdb6 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Sat, 5 Sep 2009 20:23:21 -0700 Subject: IB/ipath: strncpy() doesn't always NUL-terminate strlcpy() will always null terminate the string. node_desc is not guaranteed to be NUL-terminated so just use memcpy().
