[ Upstream commit f76936d07c4eeb36d8dbb64ebd30ab46ff85d9f7 ]
fib_nh_match does not match nexthops correctly. Example:
ip route add 172.16.10/24 nexthop via 192.168.122.12 dev eth0 \
nexthop via 192.168.122.13 dev eth0
ip route del 172.16.10/24 nexthop via 192.168.122.14 dev eth0 \
nexthop via 192.168.122.15 dev eth0
Del command is successful and route is removed. After this patch
applied, the route is correctly matched and result is:
RTNETLINK answers: No such process
Please consider this for stable trees as well.
Fixes: 4e902c57417c4 ("[IPv4]: FIB configuration using struct fib_config")
