Such clients must be reached by directly using the LAN instead of the mesh. This was introduced by 30cfd02b60e1cb16f5effb0a01f826c5bb7e4c59 ("batman-adv: detect not yet announced clients") Reported-by: Glen Page Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner --- diff --git a/net/batman-adv/translation-table.c b/net/batman-adv/translation-table.c index fec1a00a0699..baae71585804 100644 --- a/net/batman-adv/translation-table.c +++ b/net/batman-adv/translation-table.c @@ -2456,6 +2456,13 @@ bool batadv_tt_add_temporary_global_entry(struct batadv_priv *bat_priv, { bool ret = false; + /* if the originator is a backbone node (meaning it belongs to the same + * LAN of this node) the temporary client must not be added because to + * reach such destination the node must use the LAN instead of the mesh + */ + if (batadv_bla_is_backbone_gw_orig(bat_priv, orig_node->orig)) + goto out; + if (!batadv_tt_global_add(bat_priv, orig_node, addr, BATADV_TT_CLIENT_TEMP, atomic_read(&orig_node->last_ttvn)))
