selftests: forwarding: gre_multipath: Fix flower filters

2019-08-29T06:30:04Z

[ Upstream commit 1be79d89b7ae96e004911bd228ce8c2b5cc6415f ] The TC filters used in the test do not work with veth devices because the outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.

selftests: forwarding: gre_multipath: Enable IPv4 forwarding

2019-08-29T06:30:03Z

[ Upstream commit efa7b79f675da0efafe3f32ba0d6efe916cf4867 ] The test did not enable IPv4 forwarding during its setup phase, which causes the test to fail on machines where IPv4 forwarding is disabled.

selftests: set sysctl bc_forwarding properly in router_broadcast.sh

2019-06-03T22:15:01Z

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. Fixes: 40f98b9af943 ("selftests: add a selftest for directed broadcast forwarding") Signed-off-by: Xin Long Signed-off-by: David S. Miller

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

2019-04-07T01:30:04Z

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. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

selftests: forwarding: Test action VLAN modify

2019-03-29T00:20:52Z

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. Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller
