selftests: net: fix spelling and grammar mistakes

2025-09-01T20:08:07Z

Fix several spelling and grammatical mistakes in output messages from the net selftests to improve readability. Only the message strings for the test output have been modified. No changes to the functional logic of the tests have been made.

selftests: openvswitch: retry instead of sleep

2024-07-12T01:11:31Z

There are a couple of places where the test script "sleep"s to wait for some external condition to be met. This is error prone, specially in slow systems (identified in CI by "KSFT_MACHINE_SLOW=yes"). To fix this, add a "ovs_wait" function that tries to execute a command a few times until it succeeds. The timeout used is set to 5s for "normal" systems and doubled if a slow CI machine is detected. This should make the following work: $ vng --build \ --config tools/testing/selftests/net/config \ --config kernel/configs/debug.config $ vng --run . --user root -- "make -C tools/testing/selftests/ \ KSFT_MACHINE_SLOW=yes TARGETS=net/openvswitch run_tests" Signed-off-by: Adrian Moreno Reviewed-by: Ilya Maximets Link: https://patch.msgid.link/20240710090500.1655212-1-amorenoz@redhat.com Signed-off-by: Jakub Kicinski

selftests: openvswitch: add psample test

2024-07-06T00:45:48Z

Add a test to verify sampling packets via psample works. In order to do that, create a subcommand in ovs-dpctl.py to listen to on the psample multicast group and print samples.

selftests: openvswitch: add userspace parsing

The userspace action lacks parsing support plus it contains a bug in the name of one of its attributes. This patch makes userspace action work.

selftests: net: Use the provided dpctl rather than the vswitchd for tests.

2024-06-27T22:44:07Z

The current pmtu test infrastucture requires an installed copy of the ovs-vswitchd userspace. This means that any automated or constrained environments may not have the requisite tools to run the tests. However, the pmtu tests don't require any special classifier processing. Indeed they are only using the vswitchd in the most basic mode - as a NORMAL switch. However, the ovs-dpctl kernel utility can now program all the needed basic flows to allow traffic to traverse the tunnels and provide support for at least testing some basic pmtu scenarios. More complicated flow pipelines can be added to the internal ovs test infrastructure, but that is work for the future. For now, enable the most common cases - wide mega flows with no other prerequisites. Enhance the pmtu testing to try testing using the internal utility, first. As a fallback, if the internal utility isn't running, then try with the ovs-vswitchd userspace tools. Additionally, make sure that when the pyroute2 package is not available the ovs-dpctl utility will error out to properly signal an error has occurred and skip using the internal utility.

selftests: openvswitch: Support implicit ipv6 arguments.

2024-06-27T22:44:07Z

The current iteration of IPv6 support requires explicit fields to be set in addition to not properly support the actual IPv6 addresses properly. With this change, make it so that the ipv6() bare option is usable to create wildcarded flows to match broad swaths of ipv6 traffic.

selftests: openvswitch: Add support for tunnel() key.

2024-06-27T22:44:07Z

This will be used when setting details about the tunnel to use as transport. There is a difference between the ODP format between tunnel(): the 'key' flag is not actually a flag field, so we don't support it in the same way that the vswitchd userspace supports displaying it.

selftests: openvswitch: Add set() and set_masked() support.

2024-06-27T22:44:07Z

These will be used in upcoming commits to set specific attributes for interacting with tunnels. Since set() will use the key parsing routine, we also make sure to prepend it with an open paren, for the action parsing to properly understand it.
