selftests: Migrate nsim-only MACsec tests to Python

2026-04-10T02:38:41Z

Move MACsec offload API and ethtool feature tests from tools/testing/selftests/drivers/net/netdevsim/macsec-offload.sh to tools/testing/selftests/drivers/net/macsec.py using the NetDrvEnv framework so tests can run against both netdevsim (default) and real hardware (NETIF=ethX). As some real hardware requires MACsec to use encryption, add that to the tests. Netdevsim-specific limit checks (max SecY, max RX SC) were moved into separate test cases to avoid failures on real hardware.

selftest: netdevsim: Add resource dump and scope filter test

2026-04-09T02:55:39Z

Add resource_dump_test() which verifies dumping resources for all devices and ports, and tests that scope=dev returns only device-level resources and scope=port returns only port resources. Skip if userspace does not support the scope parameter.

selftests: netdevsim: add carrier state consistency test

2026-01-07T02:04:01Z

This commit adds a test case for netdevsim carrier state consistency. Specifically, the added test verifies the carrier state during the following operations: 1. Unlink two netdevsims 2. ifdown one netdevsim, then ifup again 3. Link the netdevsims again 4. ifdown one netdevsim, then ifup again These steps verifies that the carrier is UP iff two netdevsims are linked and ifuped.

selftest: netdevsim: test devlink default params

2025-11-21T03:01:23Z

Test querying default values and resetting to default values for netdevsim devlink params. This should cover the basic paths of interest: driverinit and non-driverinit cmodes, as well as bool and non-bool value type. Default param values of type bool are encoded with u8 netlink type as opposed to flag type, so that userspace can distinguish "not-present" from false.

selftests: drv-net: replace the nsim ring test with a drv-net one

2025-10-31T00:32:18Z

We are trying to move away from netdevsim-only tests and towards tests which can be run both against netdevsim and real drivers. Replace the simple bash script we have for checking ethtool -g/-G on netdevsim with a Python test tweaking those params as well as channel count. The new test is not exactly equivalent to the netdevsim one, but real drivers don't often support random ring sizes, let alone modifying max values via debugfs.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06Z

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.
