selftests: vxlan_mdb: Fix failures with old libnet

2024-03-26T11:29:25Z

Locally generated IP multicast packets (such as the ones used in the test) do not perform routing and simply egress the bound device. However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding: Fix failing tests with old libnet"), old versions of libnet (used by mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically, the library started using the option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6 ones are passing. Fix by specifying the source and destination MAC of the packets which will cause mausezahn to use a packet socket instead of an IP socket.

selftests: net: Add VXLAN MDB test

2023-03-17T08:05:50Z

Add test cases for VXLAN MDB, testing the control and data paths. Two different sets of namespaces (i.e., ns{1,2}_v4 and ns{1,2}_v6) are used in order to test VXLAN MDB with both IPv4 and IPv6 underlays, respectively. Example truncated output: # ./test_vxlan_mdb.sh [...] Tests passed: 620 Tests failed: 0 Signed-off-by: Ido Schimmel Reviewed-by: Nikolay Aleksandrov Signed-off-by: David S. Miller
