From: David Ahern Date: Tue, 3 Sep 2019 22:22:12 +0000 (-0700) Subject: ipv6: Fix RTA_MULTIPATH with nexthop objects X-Git-Tag: v5.15~5584^2~40^2~1 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=4255ff0544ee307e9a8acf66000e6fd49e9203f8;p=mirror_ubuntu-kernels.git ipv6: Fix RTA_MULTIPATH with nexthop objects A change to the core nla helpers was missed during the push of the nexthop changes. rt6_fill_node_nexthop should be calling nla_nest_start_noflag not nla_nest_start. Currently, iproute2 does not print multipath data because of parsing issues with the attribute.
