selftests: drv-net: Bring back tool() to driver inits

2026-01-17T15:35:28+00:00

[ Upstream commit 353cfc0ef3f34ef7fe313ae38dac37f2454a7cf5 ] The pp_alloc_fail.py test (which doesn't run in NIPA CI?) uses tool, add back the import.

selftests: drv-net: psp: add tests for destroying devices

2025-09-30T13:17:22+00:00

Add tests for making sure device can disappear while associations exist. This is netdevsim-only since destroying real devices is more tricky.

selftests: net: py: don't default to shell=True

2025-09-02T23:09:36+00:00

Overhead of using shell=True is quite significant. Micro-benchmark of running ethtool --help shows that non-shell run is 2x faster. Runtime of the XDP tests also shows improvement: this patch: 2m34s 2m21s 2m18s 2m18s before: 2m54s 2m36s 2m34s Reviewed-by: Breno Leitao Link: https://patch.msgid.link/20250830184317.696121-2-kuba@kernel.org Signed-off-by: Jakub Kicinski

net: selftests: clean up tools/testing/selftests/net/lib/py/utils.py

2025-09-02T22:51:16+00:00

This patch improves the utils.py module by removing unused imports (errno, random), simplifying the fd_read_timeout() function by eliminating unnecessary else clause, and cleaning up code style in the defer class constructor. Additionally, it renames the parameter in rand_port() from 'type' to 'stype' to avoid shadowing the built-in Python name 'type', improving code clarity and preventing potential issues. These changes enhance code readability and maintainability without affecting functionality.

selftests: drv-net: wait for carrier

2025-08-15T00:44:46+00:00

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: net: terminate bkg() commands on exception

2025-08-13T01:27:42+00:00

There is a number of: with bkg("socat ..LISTEN..", exit_wait=True) uses in the tests. If whatever is supposed to send the traffic fails we will get stuck in the bkg(). Try to kill the process in case of exception, to avoid the long wait. A specific example where this happens is the devmem Tx tests.

selftests: net: prevent Python from buffering the output

2025-07-17T23:27:38+00:00

Make sure Python doesn't buffer the output, otherwise for some tests we may see false positive timeouts in NIPA. NIPA thinks that a machine has hung if the test doesn't print anything for 3min. This is also nice to heave for running the tests manually, especially in vng.
