[ Upstream commit 0add5c597f3253a9c6108a0a81d57f44ab0d9d30 ]
Due to a small omission, the offload_failed flag is missing from ipv4
fibmatch results. Make sure it is set correctly.
The issue can be witnessed using the following commands:
echo "1 1" > /sys/bus/netdevsim/new_device
ip link add dummy1 up type dummy
ip route add 192.0.2.0/24 dev dummy1
echo 1 > /sys/kernel/debug/netdevsim/netdevsim1/fib/fail_route_offload
ip route add 198.51.100.0/24 dev dummy1
ip route
# 192.168.15.0/24 has rt_trap
# 198.51.100.0/24 has rt_offload_failed
ip route get 192.168.15.1 fibmatch
# Result has rt_trap
ip route get 198.51.100.1 fibmatch
# Result differs from the route shown by `ip route`, it is missing
# rt_offload_failed
ip link del dev dummy1
echo 1 > /sys/bus/netdevsim/del_device
