3.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Barth <cy...@openwrt.org>
[ Upstream commit 73ba57bfae4a1914f6a6dac71e3168dd900e00af ]
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
