selftests: Add MACsec VLAN propagation traffic test

2026-04-10T02:38:42+00:00

Add VLAN filter propagation tests through offloaded MACsec devices via actual traffic. The tests create MACsec tunnels with matching SAs on both endpoints, stack VLANs on top, and verify connectivity with ping. Covered: - Offloaded MACsec with VLAN (filters propagate to HW) - Software MACsec with VLAN (no HW filter propagation) - Offload on/off toggle and verifying traffic still works On netdevsim this makes use of the VLAN filter debugfs file to actually validate that filters are applied/removed correctly. On real hardware the traffic should validate actual VLAN filter propagation.

selftests: drv-net: give HW stats sync time extra 25% of margin

2026-03-19T23:57:28+00:00

There are transient failures for devices which update stats periodically, especially if it's the FW DMA'ing the stats rather than host periodic work querying the FW. Wait 25% longer than strictly necessary. For devices which don't report stats-block-usecs we retain 25 msec as the default wait time (0.025sec == 20,000usec * 1.25).

selftests/net: Add env for container based tests

2026-03-06T21:11:17+00:00

Add an env NetDrvContEnv for container based selftests. This automates the setup of a netns, netkit pair with one inside the netns, and a BPF program that forwards skbs from the NETIF host inside the container. Currently only netkit is used, but other virtual netdevs e.g. veth can be used too. Expect netkit container datapath selftests to have a publicly routable IP prefix to assign to netkit in a container, such that packets will land on eth0. The BPF skb forward program will then forward such packets from the host netns to the container netns.

selftests/net: Make NetDrvContEnv support queue leasing

2026-01-20T10:58:50+00:00

Add a new parameter `lease` to NetDrvContEnv that sets up queue leasing in the env. The NETIF also has some ethtool parameters changed to support memory provider tests. This is needed in NetDrvContEnv rather than individual test cases since the cleanup to restore NETIF can't be done, until the netns in the env is gone.

selftests: drv-net: psp: Better control the used PSP dev

2026-01-10T22:44:05+00:00

The PSP responder fails when zero or multiple PSP devices are detected. There's an option to select the device id to use (-d) but it's currently not used from the PSP self test. It's also hard to use because the PSP test doesn't dump the PSP devices so can't choose one. When zero devices are detected, psp_responder fails which will cause the parent test to fail as well instead of skipping PSP tests. Fix both of these problems. Change psp_responder to: - not fail when no PSP devs are detected. - get an optional -i ifindex argument instead of -d. - select the correct PSP dev from the dump corresponding to ifindex or - select the first PSP dev when -i is not given. - fail when multiple devs are found and -i is not given. - warn and continue when the requested ifindex is not found. Also plumb the ifindex from the Python test. With these, when there are no PSP devs found or the wrong one is chosen, psp_responder opens the server socket, listens for control connections normally, and leaves the skipping of the various test cases which require a PSP device (~most, but not all of them) to the parent test. This results in output like: ok 1 psp.test_case # SKIP No PSP devices found [...] ok 12 psp.dev_get_device # SKIP No PSP devices found ok 13 psp.dev_get_device_bad ok 14 psp.dev_rotate # SKIP No PSP devices found [...] Signed-off-by: Cosmin Ratiu Reviewed-by: Carolina Jubran Link: https://patch.msgid.link/20260109110851.2952906-2-cratiu@nvidia.com Signed-off-by: Jakub Kicinski

We're already saving the info about the local dev in env.dev for the tests, save remote dev as well. This is more symmetric, env generally provides the same info for local and remote end. While at it make sure that we reliably get the detailed info about the local dev. nsim used to read the dev info without -d.
