commit 783c52b6df5db152cf2a3b9f85756761a6c79777 Author: Peter Palfrader <peter@palfrader.org> Date: Mon Jul 15 10:46:22 2013 +0200 Reject relative control socket paths and emit a warning. Previously we would accept relative paths, but only if they contained a slash somewhere (not at the end). Otherwise we would silently not work. Closes: #9258.
