4 | Subject: [PATCH 17/22] openvpn plugin: Don't signal an error when no clients | |
5 | are connected. | |
6 | ||
7 | In the multi1_read() function, an error (zero) was returned when no | |
8 | clients were currently connected to the OpenVPN server, because the | |
9 | "read" variable was initialized to zero and the while loop exited before | |
10 | it was set to one. This is not the intended behavior. | |
11 | ||
12 | Thanks to @srix for reporting this issue! | |

14 | Fixes: #731 | |
