selftests/net: Make NetDrvContEnv support queue leasing

2026-01-20T10:58:50Z

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/net: Add env for container based tests

2026-01-20T10:58:50Z

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

2026-01-10T22:44:05Z

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

selftests: net: py: read ip link info about remote dev

2025-11-21T02:19:29Z

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.

selftests: drv-net: wait for carrier

2025-08-15T00:44:46Z

On fast machines the tests run in quick succession so even when tests clean up after themselves the carrier may need some time to come back. Specifically in NIPA when ping.py runs right after netpoll_basic.py the first ping command fails. Since the context manager callbacks are now common NetDrvEpEnv gets an ip link up call as well.

selftests: drv-net: Fix remote command checking in require_cmd()

2025-07-25T01:52:00Z

The require_cmd() method was checking for command availability locally even when remote=True was specified, due to a missing host parameter. Fix by passing host=self.remote when checking remote command availability, ensuring commands are verified on the correct host.
