for throw routes to trigger evaluation of other policy rules EAGAIN needs to be propagated up to fib_rules_lookup similar to how its done for IPv4 A simple testcase for verification is: ip -6 rule add lookup 33333 priority 33333 ip -6 route add throw 2001:db8::1 ip -6 route add 2001:db8::1 via fe80::1 dev wlan0 table 33333 ip route get 2001:db8::1 Signed-off-by: Steven Barth <[email protected]> Signed-off-by: David S.
