From: Eric Garver Date: Tue, 23 May 2017 22:37:27 +0000 (-0400) Subject: geneve: fix fill_info when using collect_metadata X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11387fe4a98f75d1f4cdb3efe3b42b19205c9df5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git geneve: fix fill_info when using collect_metadata 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.
