2025-03-12selftests: net: bump GRO timeout for gro/setup_vethJakub Kicinski
Commit 51bef03e1a71 ("selftests/net: deflake GRO tests") recently switched to NAPI suspension, and lowered the timeout from 1ms to 100us. This started causing flakes in netdev-run CI. Let's bump it to 200us. In a quick test of a debug kernel I see failures with 100us, with 200us in 5 runs I see 2 completely clean runs and 3 with a single retry (GRO test will retry up to 5 times).

2025-03-10selftests: drv-net: add xdp cases for ping.pyTaehee Yoo
ping.py has 3 cases, test_v4, test_v6 and test_tcp. But these cases are not executed on the XDP environment. So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generic + multi-buffer 3. xdp-native + single-buffer 4. xdp-native + multi-buffer 5. xdp-offload It also makes test_{v4 | v6 | tcp} sending large size packets. this may help to check whether multi-buffer is working or not. Note that the physical interface may be down and then up when xdp is attached or detached. This takes some period to activate traffic. So sleep(10) is added if the test interface is the physical interface. netdevsim and veth type interfaces skip sleep.

2025-02-27selftests/net: deflake GRO testsKevin Krakauer
GRO tests are timing dependent and can easily flake. This is partially mitigated in gro.sh by giving each subtest 3 chances to pass. However, this still flakes on some machines. Reduce the flakiness by: - Bumping retries to 6. - Setting napi_defer_hard_irqs to 1 to reduce the chance that GRO is flushed prematurely. This also lets us reduce the gro_flush_timeout from 1ms to 100us. Tested: Ran `gro.sh -t large` 1000 times. There were no failures with this change. Ran inside strace to increase flakiness.

2025-02-18selftests: forwarding: lib: Move require_command to net, generalizePetr Machata
This helper could be useful to more than just forwarding tests. Move it upstairs and port over to log_test_skip(). Split the function into two parts: the bit that actually checks and reports skip, which is in a new function check_command(). And a bit that exits the test script if the check fails. This allows users consistent checking behavior while giving an option to bail out from a single test without bailing out of the whole script.

2025-02-05selftests: mptcp: connect: -f: no reconnectMatthieu Baerts (NGI0)
The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored. The recent modification only shown an existing issue: xdisconnect() doesn't need to be used here, only the shutdown() part is needed.
