From c095f248e63ada504dd90c90baae673ae10ee3fe Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Mon, 15 Sep 2014 15:24:26 -0400 Subject: bridge: Fix br_should_learn to check vlan_enabled As Toshiaki Makita pointed out, the BRIDGE_INPUT_SKB_CB will not be initialized in br_should_learn() as that function is called only from br_handle_local_finish(). That is an input handler for link-local ethernet traffic so it perfectly correct to check br->vlan_enabled here. Reported-by: Toshiaki Makita Fixes: 20adfa1 bridge: Check if vlan filtering is enabled only once. Signed-off-by: Vladislav Yasevich Signed-off-by: David S.
