selftests: forwarding: Specify interface when invoking mausezahn

2021-01-28T21:09:01+00:00

Specify the interface through which packets should be transmitted so
that the test will pass regardless of the libnet version against which
mausezahn is linked.

selftests: forwarding: Add MPLS L2VPN test

2020-12-05T01:44:06+00:00

Connect hosts H1 and H2 using two intermediate encapsulation routers
(LER1 and LER2). These routers encapsulate traffic from the hosts,
including the original Ethernet header, into MPLS.

Use ping to test reachability between H1 and H2.

selftests: forwarding: Add blackhole nexthops tests

2020-11-24T20:14:56+00:00

Test that IPv4 and IPv6 ping fail when the route is using a blackhole
nexthop or a group with a blackhole nexthop. Test that ping passes when
the route starts using a valid nexthop.

selftests: forwarding: Add multipath tunneling nexthop test

2020-11-20T23:20:21+00:00

Add a nexthop objects version of gre_multipath.sh. Unlike the original
test, it also tests IPv6 overlay which is not possible with the legacy
nexthop implementation. See commit 9a2ad3623868 ("selftests: forwarding:
gre_multipath: Drop IPv6 tests") for more info.

selftests: forwarding: Add device-only nexthop test

2020-11-20T23:20:20+00:00

In a similar fashion to router_multipath.sh and its nexthop objects
version router_mpath_nh.sh, create a nexthop objects version of
router.sh.

It reuses the same topology, but uses device-only nexthop objects
instead of legacy ones.

selftests: forwarding: Test IPv4 routes with IPv6 link-local nexthops

2020-11-20T23:20:20+00:00

In addition to IPv4 multipath tests with IPv4 nexthops, also test IPv4
multipath with nexthops that use IPv6 link-local addresses.

selftests: forwarding: Do not configure nexthop objects twice

2020-11-20T23:20:20+00:00

routing_nh_obj() is used to configure the nexthop objects employed by
the test, but it is called twice resulting in "RTNETLINK answers: File
exists" messages.

Remove the first call, so that the function is only called after
setup_wait(), when all the interfaces are up and ready.

selftests: net: bridge: add test for mldv2 *,g auto-add

2020-11-05T00:55:48+00:00

When we have *,G ports in exclude mode and a new S,G,port is added
the kernel has to automatically create an S,G entry for each exclude
port to get proper forwarding.

selftests: net: bridge: add test for mldv2 exclude timeout

2020-11-05T00:55:48+00:00

Test that when a group in exclude mode expires it changes mode to
include and the blocked entries are deleted.
