From 1a9070ec91b37234fe915849b767c61584c64a44 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 4 Mar 2017 15:48:50 +0100 Subject: batman-adv: Initialize gw sel_class via batadv_algo The gateway selection class variable is shared between different algorithm versions. But the interpretation of the content is algorithm specific. The initialization is therefore also algorithm specific. But this was implemented incorrectly and the initialization for BATMAN_V always overwrote the value previously written for BATMAN_IV. This could only be avoided when BATMAN_V was disabled during compile time. Using a special batadv_algo hook for this initialization avoids this problem. Fixes: 50164d8f500f ("batman-adv: B.A.T.M.A.N. V - implement GW selection logic") Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich --- net/batman-adv/gateway_common.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'net/batman-adv/gateway_common.c') diff --git a/net/batman-adv/gateway_common.c b/net/batman-adv/gateway_common.c index 21184810d89f..3e3f91ab694f 100644 --- a/net/batman-adv/gateway_common.c +++ b/net/batman-adv/gateway_common.c @@ -253,6 +253,11 @@ static void batadv_gw_tvlv_ogm_handler_v1(struct batadv_priv *bat_priv, */ void batadv_gw_init(struct batadv_priv *bat_priv) { + if (bat_priv->algo_ops->gw.init_sel_class) + bat_priv->algo_ops->gw.init_sel_class(bat_priv); + else + atomic_set(&bat_priv->gw.sel_class, 1); + batadv_tvlv_handler_register(bat_priv, batadv_gw_tvlv_ogm_handler_v1, NULL, BATADV_TVLV_GW, 1, BATADV_TVLV_HANDLER_OGM_CIFNOTFND); -- cgit
