net: Flush local routes when device changes vrf association

2015-12-14T04:58:44+00:00

The VRF driver cycles netdevs when an interface is enslaved or released: the down event is used to flush neighbor and route tables and the up event (if the interface was already up) effectively moves local and connected routes to the proper table. As of 4f823defdd5b the local route is left hanging around after a link down, so when a netdev is moved from one VRF to another (or released from a VRF altogether) local routes are left in the wrong table. Fix by handling the NETDEV_CHANGEUPPER event. When the upper dev is an L3mdev then call fib_disable_ip to flush all routes, local ones to.

ipv4: fix to not remove local route on link down

2015-11-01T21:57:39+00:00

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.

ipv4: implement support for NOPREFIXROUTE ifa flag for ipv4 address

2015-10-23T09:54:54+00:00

Currently adding a new ipv4 address always cause the creation of the related network route, with default metric. When a host has multiple interfaces on the same network, multiple routes with the same metric are created. If the userspace wants to set specific metric on each routes, i.e. giving better metric to ethernet links in respect to Wi-Fi ones, the network routes must be deleted and recreated, which is error-prone. This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4 address. When an address is added with such flag set, no associated network route is created, no network route is deleted when said IP is gone and it's up to the user space manage such route.
