From 60040513536097584c3d55b39acdfa7080645d80 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Fri, 23 Nov 2018 12:14:56 +0100 Subject: batman-adv: Prepare framework for mesh genl config The batman-adv configuration interface was implemented solely using sysfs. This approach was condemned by non-batadv developers as "huge mistake". Instead a netlink/genl based implementation was suggested. The main objects for this configuration is the mesh/soft-interface object. Its actual object in memory already contains most of the available configuration settings. The genl interface reflects this by allowing to get/set it using the mesh specific commands. The BATADV_CMD_GET_MESH_INFO (or short version BATADV_CMD_GET_MESH) is reused as get command because it already provides the content of other information from the mesh/soft-interface which are not yet configuration specific. The set command BATADV_CMD_SET_MESH will also notify interested userspace listeners of the "config" mcast group using the BATADV_CMD_SET_MESH command message type that settings might have been changed and what the current values are.
