The following commit has been merged in the master branch: commit 5f320f09b3d93200eb61eb9a26e1d2b3078eb712 Author: Martin Weinelt <martin(a)linuxlounge.net> Date: Wed Feb 6 15:39:14 2019 +0100 batman-adv: fix memory leak in in batadv_dat_put_dhcp batadv_dat_put_dhcp is creating a new ARP packet via batadv_dat_arp_create_reply and tries to forward it via batadv_dat_send_data to different peers in the DHT. The original skb is not consumed by batadv_dat_send_data and thus has to be consumed by the caller.
