From 4f823defdd5b106a5e89745ee8b163c71855de1e Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Fri, 30 Oct 2015 10:23:33 +0200 Subject: ipv4: fix to not remove local route on link down When fib_netdev_event calls fib_disable_ip on NETDEV_DOWN event we should not delete the local routes if the local address is still present. The confusion comes from the fact that both fib_netdev_event and fib_inetaddr_event use the NETDEV_DOWN constant. Fix it by returning back the variable 'force'. Steps to reproduce: modprobe dummy ifconfig dummy0 192.168.168.1 up ifconfig dummy0 down ip route list table local | grep dummy | grep host local 192.168.168.1 dev dummy0 proto kernel scope host src 192.168.168.1 Fixes: 8a3d03166f19 ("net: track link-status of ipv4 nexthops") Signed-off-by: Julian Anastasov Signed-off-by: David S.
