[PATCH 3.12 009/155] ipv6: fix backtracking for throw routes
From: Jiri Slaby
Date: Tue Apr 07 2015 - 09:18:58 EST
From: Steven Barth <cyrus@xxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
[ 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
