Lower the expected level of traffic in the pp_alloc_fail test and calculate failure counter thresholds based on the traffic rather than using a fixed constant. We only have "QEMU HW" in NIPA right now, and the test (due to debug dependencies) only works on debug kernels in the first place. We need some place for it to pass otherwise it seems to be bit rotting. So lower the traffic threshold so that it passes on QEMU and with a debug kernel...

2025-10-07selftests: drv-net: make linters happy with our importsJakub Kicinski2-11/+33
Linters are still not very happy with our __init__ files, which was pointed out in recent review (see Link). We have previously started importing things one by one to make linters happy with the test files (which import from __init__). But __init__ file itself still makes linters unhappy. To clean it up I believe we must completely remove the wildcard imports, and assign the imported modules to __all__. hds.py needs to be fixed because it seems to be importing the Python standard random from lib.net. We can't use ksft_pr() / ktap_result() in case importing from net.lib fails. Linters complain that those helpers themselves may not have been imported.

RX devmem sometimes fails on NIPA: https://netdev-3.bots.linux.dev/vmksft-fbnic-qemu-dbg/results/294402/7-devmem-py/ Both RSS and flow steering are properly installed, but the wait_port_listen fails. Try to remove sleep(1) to see if the cause of the failure is spending too much time during RX setup. I don't see a good reason to have sleep in the first place. If there needs to be a delay between installing the rules and receiving the traffic, let's add it to the callers (devmem.py) instead.

2025-09-05selftests: ncdevmem: don't retry EFAULTStanislav Fomichev1-0/+4
devmem test fails on NIPA. Most likely we get skb(s) with readable frags (why?) but the failure manifests as an OOM. The OOM happens because ncdevmem spams the following message: recvmsg ret=-1 recvmsg: Bad address As of today, ncdevmem can't deal with various reasons of EFAULT: - falling back to regular recvmsg for non-devmem skbs - increasing ctrl_data size (can't happen with ncdevmem's large buffer) Exit (cleanly) with error when recvmsg returns EFAULT. This should at least cause the test to cleanup its state.

2025-09-02selftests: drv-net: rss_ctx: use Netlink for timed reconfigJakub Kicinski1-3/+4
The rss_ctx test has gotten pretty flaky after I increased the queue count in NIPA 2->3. Not 100% clear why. We get a lot of failures in the rss_ctx.test_hitless_key_update case. Looking closer it appears that the failures are mostly due to startup costs. I measured the following timing for ethtool -X: - python cmd(shell=True) : 150-250msec - python cmd(shell=False) : 50- 70msec - timed in bash : 45- 55msec - YNL Netlink call : 2- 4msec - .set_rxfh callback : 1- 2msec The target in the test was set to 200msec. We were mostly measuring ethtool startup cost it seems. Switch to YNL since it's 100x faster. Lower the pass criteria to 150msec, no real science behind this number but we removed some overhead, drivers which previously passed 200msec should easily pass 150msec now. Separately we should probably follow up on defaulting to shell=False, when script doesn't explicitly ask for True, because the overhead is rather significant. Switch from _rss_key_rand() to random.randbytes(), YNL takes a binary array rather than array of ints.

Kernel tries to be helpful and attach the XDP program in generic mode if the driver has no BPF ndo at all. Since the xdp.py tests all have "native" in their names this can be quite confusing. Force native / "drv" attachment. Note that netdevsim re-uses the generic handler as its "native" handler, so we'll maintain the test coverage of the generic mode that way. No need to test both explicitly, I reckon. Link: https://patch.msgid.link/20250822195645.1673390-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

channels ncdevmem tests that the kernel correctly rejects attempts to deactivate queues with MPs bound. Make the configure_channels() test support combined channels. Currently it tries to set the queue counts to rx N tx N-1, which only makes sense for devices which have IRQs per ring type. Most modern devices used combined IRQs/channels with both Rx and Tx queues. Since the math is total Rx == combined+Rx setting Rx when combined is non-zero will be increasing the total queue count, not decreasing as the test intends. Note that the test would previously also try to set the Tx ring count to Rx - 1, for some reason. Which would be 0 if the device has only 2 queues configured. With this change (device with 2 queues): setting channel count rx:1 tx:1 YNL set channels: Kernel error: 'requested channel counts are too low for existing memory provider setting (2)' Reviewed-by: Mina Almasry <almasrymina@google.com> Link: https://patch.msgid.link/20250815231513.381652-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
