4.2.8-ckt2 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Sabrina Dubroca <sd@xxxxxxxxxxxxxxx>
commit a534dc529853c69e94994aa47c1d80a03ce2c11d upstream.
ipvlan_handle_frame is a rx_handler, and when it returns a value other
than RX_HANDLER_CONSUMED (here, NET_RX_DROP aka RX_HANDLER_ANOTHER),
__netif_receive_skb_core expects that the skb still exists and will
process it further, but we just freed it.
Fixes: 2ad7bf363841 ("ipvlan: Initial check-in of the IPVLAN driver.")
