The following commit has been merged in the merge/master branch: commit 1aaa327c15d61fd5e8a32e07d8f1cf28e5780d8c Author: Sven Eckelmann &lt;sven(a)narfation.org&gt; Date: Fri Jun 10 18:14:00 2016 +0200 batman-adv: Avoid skb free for batadv_send_skb_to_orig < -1 The tp_meter code frees the skb when the batadv_send_skb_to_orig returns < 0. But the batadv_send_skb_to_orig only defines -1 as return code for failed submits with still valid skbs.
