selftests: set sysctl bc_forwarding properly in router_broadcast.sh

2019-06-03T22:15:01+00:00

sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2,
otherwise the bc packets from $rp2 won't be forwarded. This patch is to
add this setting for $rp2.

Also, as ping_test_from does grep "$from" only, which could match some
unexpected output, some test case doesn't really work, like:

  # ping_test_from $h2 198.51.200.255 198.51.200.2
    PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data.
    64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms

When doing grep $form (198.51.200.2), the output could still match.
So change to grep "bytes from $from" instead.

selftests: forwarding: test for bridge mcast traffic after report and leave

2019-04-07T01:30:04+00:00

This test is split in two, the first part checks if a report creates a
corresponding mdb entry and if traffic is properly forwarded to it, and
the second part checks if the mdb entry is deleted after a leave and
if traffic is *not* forwarded to it. Since the mcast querier is enabled
we should see standard mcast snooping bridge behaviour.

selftests: forwarding: Test action VLAN modify

2019-03-29T00:20:52+00:00

Construct a basic topology consisting of two hosts connected using a
VLAN-aware bridge. Put each port in a different VLAN and test that ping
fails.

Add ingress and egress filters with a VLAN modify action and test that
ping passes.

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

2019-03-29T00:20:52+00:00

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.
