Thus packets converted from broadcast to unicast via +the gateway handling code have to be converted to 4addr packets to allow +the receiving gateway server to add the sender address as temporary entry +to the translation table. + +Not doing it will make the batman-adv gateway server drop the DHCP response +in many situations because it doesn't yet have the TT entry for the +destination of the DHCP response. + +Fixes: 9cbc67d9da47 ("batman-adv: change interface_rx to get orig node") +Signed-off-by: Sven Eckelmann +--- + net/batman-adv/send.c | 4 ++-- + 1 file changed, 2 insertions(+), 2 deletions(-) + +diff --git a/net/batman-adv/send.c b/net/batman-adv/send.c +index f2f1256..0103976 100644 +--- a/net/batman-adv/send.c ++++ b/net/batman-adv/send.c +@@ -424,8 +424,8 @@ int batadv_send_skb_via_gw(struct batadv_priv *bat_priv, struct sk_buff *skb, + struct batadv_orig_node *orig_node; + + orig_node = batadv_gw_get_selected_orig(bat_priv); +- return batadv_send_skb_unicast(bat_priv, skb, BATADV_UNICAST, 0, +- orig_node, vid); ++ return batadv_send_skb_unicast(bat_priv, skb, BATADV_UNICAST_4ADDR, ++ BATADV_P_DATA, orig_node, vid); + } + + void batadv_schedule_bat_ogm(struct batadv_hard_iface *hard_iface)
