From 34dde6c0046dfb7e4a6c65c5e17c7e035145f3fa Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Wed, 20 Nov 2019 15:39:06 +0800 Subject: [PATCH] ipv6/route: return if there is no fib_nh_gw_family [ Upstream commit 004b39427f945696db30abb2c4e1a3856ffff819 ] Previously we will return directly if (!rt || !rt->fib6_nh.fib_nh_gw_family) in function rt6_probe(), but after commit cc3a86c802f0 ("ipv6: Change rt6_probe to take a fib6_nh"), the logic changed to return if there is fib_nh_gw_family.
