From adb4b83c12f9d966ea3478aa14c60511467c9916 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 15 Mar 2010 07:28:00 -0500 Subject: kgdboc,kgdbts: strlen() doesn't count the terminator This is an off by one because strlen() doesn't count the null terminator. We strcpy() these strings into an array of size MAX_CONFIG_LEN.
