Subject: [PATCH net 0/2] wireguard: device: fix metadata_dst xmit null pointer dereference
Date: Thu, 14 Apr 2022 13:44:56 +0300	[thread overview]
Message-ID: <20220414104458.3097244-1-razor@blackwall.org> (raw)

Hi,
Patch 01 fixes a null pointer dereference in wireguard's xmit path when
transmitting skbs with metadata_dst attached. Patch 02 adds a selftest for
that case using bpf_skb_set_tunnel_key on wg device's egress path.

Thanks,
 Nik
