selftests/net: test nexthop without gw

2022-07-14T12:41:19+00:00

This test implement the scenario described in the commit "ip: fix dflt addr selection for connected nexthop". The test configures a nexthop object with an output device only (no gateway address) and a route that uses this nexthop. The goal is to check if the kernel selects a valid source address.

selftests: mptcp: validate userspace PM tests by default

2022-07-11T10:31:38+00:00

The new script was not listed in the programs to test. By consequence, some CIs running MPTCP selftests were not validating these new tests. Note that MPTCP CI was validating it as it executes all .sh scripts from 'tools/testing/selftests/net/mptcp' directory.

selftests: mptcp: userspace PM support for MP_PRIO signals

2022-07-06T11:50:26+00:00

This change updates the testing sample (pm_nl_ctl) to exercise the updated MPTCP_PM_CMD_SET_FLAGS command for userspace PMs to issue MP_PRIO signals over the selected subflow. E.g. ./pm_nl_ctl set 10.0.1.2 port 47234 flags backup token 823274047 rip 10.0.1.1 rport 50003 userspace_pm.sh has a new selftest that invokes this command.

selftests: forwarding: fix error message in learning_test

2022-07-05T09:52:33+00:00

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.

selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT

2022-07-05T09:52:33+00:00

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

2022-07-05T09:52:33+00:00

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/net: fix section name when using xdp_dummy.o

Since commit 8fffa0e3451a ("selftests/bpf: Normalize XDP section names in selftests") the xdp_dummy.o's section name has changed to xdp. But some tests are still using "section xdp_dummy", which make the tests failed. Fix them by updating to the new section name.
