selftests: forwarding: fix error message in learning_test

2022-07-12T14:30:49+00:00

[ Upstream commit 83844aacab2015da1dba1df0cc61fc4b4c4e8076 ] When packets are not received, they aren't received on $host1_if, so the message talking about the second host not receiving them is incorrect. Fix it. Fixes: d4deb01467ec ("selftests: forwarding: Add a test for FDB learning") Signed-off-by: Vladimir Oltean Reviewed-by: Ido Schimmel Signed-off-by: Paolo Abeni Signed-off-by: Sasha Levin

selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT

2022-07-12T14:30:48+00:00

[ Upstream commit 1a635d3e1c80626237fdae47a5545b6655d8d81c ] The first host interface has by default no interest in receiving packets MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc filter and this might confuse the selftest. Enable promiscuous mode such that the filter properly counts received packets.

selftests: forwarding: fix flood_unicast_test when h2 supports IFF_UNICAST_FLT

2022-07-12T14:30:48+00:00

[ Upstream commit b8e629b05f5d23f9649c901bef09fab8b0c2e4b9 ] As mentioned in the blamed commit, flood_unicast_test() works by checking the match count on a tc filter placed on the receiving interface. But the second host interface (host2_if) has no interest in receiving a packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even before the ingress tc filter gets to be executed. So we will incorrectly get the message "Packet was not flooded when should", when in fact, the packet was flooded as expected but dropped due to an unrelated reason, at some other layer on the receiving side. Force h2 to accept this packet by temporarily placing it in promiscuous mode. Alternatively we could either deliver to its MAC address or use tcpdump_start, but this has the fewest complications. This fixes the "flooding" test from bridge_vlan_aware.sh and bridge_vlan_unaware.sh, which calls flood_test from the lib.

selftests: forwarding: Make ping timeout configurable

2019-02-01T23:26:36+00:00

The current timeout (2 seconds) proved to be too low for some (emulated) systems where we run the tests. Make the timeout configurable and default to 5 seconds. Signed-off-by: Ido Schimmel Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: Add multicast routing test

2018-12-12T07:01:33+00:00

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.

selftests: forwarding: lib: Add link_stats_rx_errors_get()

2018-11-20T01:59:43+00:00

Such a function will be useful for counting malformed packets in the ECN decap test. To that end, introduce a common handler for handling stat-fetching, and reuse it in link_stats_tx_packets_get() and link_stats_rx_errors_get().
