Subject: [PATCH net-next] geneve: fix fill_info when using collect_metadata
Date: Tue, 23 May 2017 18:37:27 -0400 [thread overview]
Message-ID: <20170523223727.15307-1-e@erig.me> (raw)
Since 9b4437a5b870 ("geneve: Unify LWT and netdev handling.") fill_info
does not return UDP_ZERO_CSUM6_RX when using COLLECT_METADATA. This is
because it uses ip_tunnel_info_af() with the device level info, which is
not valid for COLLECT_METADATA.
Fix by checking for the presence of the actual sockets.
Fixes: 9b4437a5b870 ("geneve: Unify LWT and netdev handling.")
