From 691746f41a3df33f9fe26cc53f12ec16286c09fc Mon Sep 17 00:00:00 2001 From: Florian Forster Date: Sun, 14 Sep 2014 19:28:05 +0200 Subject: [PATCH] openvpn plugin: Don't signal an error when no clients are connected. In the multi1_read() function, an error (zero) was returned when no clients were currently connected to the OpenVPN server, because the "read" variable was initialized to zero and the while loop exited before it was set to one. This is not the intended behavior. Thanks to @srix for reporting this issue!
