selftests: forwarding: Add test cases for unresolved multicast routes

2022-09-20T15:22:15Z

Add IPv4 and IPv6 test cases for unresolved multicast routes, testing that queued packets are forwarded after installing a matching (S, G) route. The test cases can be used to reproduce the bugs fixed in "ipmr: Always call ip{,6}_mr_forward() from RCU read-side critical section". Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

selftests: forwarding: Add reverse path forwarding (RPF) test cases

In case a packet is routed using a multicast route whose specified ingress interface does not match the interface from which the packet was received, the packet is dropped. Add IPv4 and IPv6 test cases for above mentioned scenario. Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: Add multicast routing test

2018-12-12T07:01:33Z

Introduce basic testing for both IPv4 and IPv6 multicast. The test creates an (S,G) type route, sends traffic and verifies traffic arrives when the route is present and then verifies traffic does not arrive after deleting the route. This test requires smcroute - https://github.com/troglobit/smcroute which is a tool that allows creation of static multicast routes.
