From 80bc2072c0f8b105142f7f30f202809127af87a5 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 13 Apr 2010 10:30:28 -0700 Subject: [PATCH] ovs-ofctl: Fix write before beginning of string in "add-flow". If "action" is the first word in a flow specification, then we were writing one byte before the beginning of the string. So overwrite the 'a' in "action" instead; we know it's really there.
