selftests: drv-net: psp: fix test names in ipver_test_builder()

2025-12-23T11:05:04Z

test_case will only take on the formatted name after being called. This does not work with the way ksft_run() currently works. Assign the name after the test_case is created.

selftests: drv-net: psp: fix templated test names in psp_ip_ver_test_builder()

2025-12-23T11:05:04Z

test_case will only take on its formatted name after it is called by the test runner. Move the assignment to test_case.__name__ to when the test_case is constructed, not called.

selftests: drv-net: psp: add assertions on core-tracked psp dev stats

2025-11-08T02:53:56Z

Add assertions to existing test cases to cover key rotations and 'stale-events'. Signed-off-by: Daniel Zahka Link: https://patch.msgid.link/20251106002608.1578518-3-daniel.zahka@gmail.com Signed-off-by: Jakub Kicinski

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

2025-09-30T13:17:22Z

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

selftests: drv-net: psp: add test for auto-adjusting TCP MSS

2025-09-30T13:17:22Z

Test TCP MSS getting auto-adjusted. PSP adds an encapsulation overhead of 40B per packet, when used in transport mode without any virtualization cookie or other optional PSP header fields. The kernel should adjust the MSS for a connection after PSP tx state is reached.

selftests: drv-net: psp: add connection breaking tests

2025-09-30T13:17:22Z

Add test checking conditions which lead to connections breaking. Using bad key or connection gets stuck if device key is rotated twice.

selftests: drv-net: psp: add basic data transfer and key rotation tests

2025-09-30T13:17:22Z

Add basic tests for sending data over PSP and making sure that key rotation toggles the MSB of the spi. Deploy PSP responder on the remote end. We also need a healthy dose of common helpers for setting up the connections, assertions and interrogating socket state on the Python side.
