selftests: forwarding: Add missing 'rp_filter' configuration

2020-10-18T19:47:32Z

When 'rp_filter' is configured in strict mode (1) the tests fail because packets received from the macvlan netdevs would not be forwarded through them on the reverse path. Fix this by disabling the 'rp_filter', meaning no source validation is performed.

selftests: forwarding: Add a test case for ARP suppression

2019-01-23T04:40:35Z

ARP suppression allows the Linux bridge to answer ARP requests on behalf of remote hosts. It reduces the amount of packets a VTEP needs to flood. This test verifies that ARP suppression on / off works when a neighbour exists and when it does not exist. It does so by sending an ARP request from a host connected to one VTEP and checking whether it was received by a second VTEP.

selftests: forwarding: Add a test case for ARP decapsulation

2019-01-23T04:40:35Z

Verify that ARP packets are correctly decapsulated by the ingress VTEP by removing the neighbours configured on both VLAN interfaces and running a ping test. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: Add a test for VXLAN asymmetric routing

2019-01-23T04:40:35Z

In asymmetric routing the ingress VTEP routes the packet into the correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to the correct host. Therefore, packets in different directions use different VNIs - the target VNI. The test uses a simple topology with two VTEPs and two VNIs and verifies that ping passes between hosts (local / remote) in the same VLAN (VNI) and in different VLANs belonging to the same tenant (VRF). While the test does not check VM mobility, it does configure an anycast gateway using a macvlan device on both VTEPs. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.
