2023-02-09selftests/powerpc: Add read/write debugfs file, intBenjamin Gray5-35/+47
Debugfs files are not always integers, so make *_file return/write a byte buffer, and *_int deal with int values specifically. This increases consistency with the other file read/write helpers.

As discussed[*], relabel the poorly named structs to align with the current KVM nomenclature. Old names are a leftover from before commit 52491a38b2c2 ("KVM: Initialize gfn_to_pfn_cache locks in dedicated helper"), which i.a. introduced kvm_gpc_init() and renamed kvm_gfn_to_pfn_cache_init()/ _destroy() to kvm_gpc_activate()/_deactivate(). Partly in an effort to avoid implying that the cache really is destroyed/freed. While at it, get rid of #define GPA_INVALID, which being used as a GFN, is not only misnamed, but also unnecessarily reinvents a UAPI constant. No functional change intended.

2023-02-08selftests: mptcp: stop tests earlierMatthieu Baerts1-4/+10
These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in the background and check the status during this transfer. Once the expected events have been recorded, there is no reason to wait for the data transfer to finish. It can be stopped earlier to reduce the execution time by more than half. For these tests, the exchanged data were not verified. Errors, if any, were ignored but that's fine, plenty of other tests are looking at that. It is then OK to mute stderr now that we are sure errors will be printed (and still ignored) because the transfer is stopped before the end.

2023-02-07kselftest/arm64: Copy whole EXTRA contextMark Brown1-2/+4
When copying the EXTRA context our calculation of the amount of data we need to copy is incorrect, we only calculate the amount of data needed within uc_mcontext.__reserved, not taking account of the fixed portion of the context. Add in the offset of the reserved data so that we copy everything we should. This will only cause test failures in cases where the last context in the EXTRA context is smaller than the missing data since we don't currently validate any of the register data and all the buffers we copy into are statically allocated so default to zero meaning that if we walk beyond the end of what we copied we'll encounter what looks like a context with magic and length both 0 which is a valid terminator record.

2023-02-06selftests: forwarding: lib: Add helpers for checksum handlingPetr Machata1-0/+56
In order to generate IGMPv3 and MLDv2 packets on the fly, we will need helpers to calculate the packet checksum. The approach presented in this patch revolves around payload templates for mausezahn. These are mausezahn-like payload strings (01:23:45:...) with possibly one 2-byte sequence replaced with the word PAYLOAD. The main function is payload_template_calc_checksum(), which calculates RFC 1071 checksum of the message. There are further helpers to then convert the checksum to the payload format, and to expand it. For IPv6, MLDv2 message checksum is computed using a pseudoheader that differs from the header used in the payload itself. The fact that the two messages are different means that the checksum needs to be returned as a separate quantity, instead of being expanded in-place in the payload itself. Furthermore, the pseudoheader includes a length of the message. Much like the checksum, this needs to be expanded in mausezahn format. And likewise for number of addresses for (S,G) entries. Thus we have several places where a computed quantity needs to be presented in the payload format. Add a helper u16_to_bytes(), which will be used in all these cases.

2023-02-04kselftest/alsa: Run PCM tests for multiple cards in parallelMark Brown2-8/+74
With each test taking 4 seconds the runtime of pcm-test can add up. Since generally each card in the system is physically independent and will be unaffected by what's going on with other cards we can mitigate this by testing each card in parallel. Make a list of cards as we enumerate the system and then start a thread for each, then join the threads to ensure they have all finished. The threads each run the same tests we currently run for each PCM on the card before exiting. The list of PCMs is kept global since it helps with global operations like working out our planned number of tests and identifying missing PCMs and it seemed neater to check for PCMs on the right card in the card thread than make every PCM loop iterate over cards as well. We don't run per-PCM tests in parallel since in embedded systems it can be the case that resources are shared between the PCMs and operations on one PCM on a card may constrain what can be done on another PCM on the same card leading to potentially unstable results. We use a mutex to ensure that the reporting of results is serialised and we don't have issues with anything like the current test number, we could do this in the kselftest framework but it seems like this might cause problems for other tests that are doing lower level testing and building in constrained environments such as nolibc so this seems more sensible. Note that the ordering of the tests can't be guaranteed as things stand, this does not seem like a major problem since the numbering of tests often changes as test programs are changed so results parsers are expected to rely on the test name rather than the test numbers. We also now prefix the machine generated test name when printing the description of the test since this is logged before streaming starts. On my two card desktop system this reduces the overall runtime by a third.

2023-02-02selftests/damon/sysfs: hide expected write failuresSeongJae Park1-1/+1
DAMON selftests for sysfs (sysfs.sh) tests if some writes to DAMON sysfs interface files fails as expected. It makes the test results noisy with the failure error message because it tests a number of such failures. Redirect the expected failure error messages to /dev/null to make the results clean.

2023-02-02selftests/bpf: introduce XDP compliance test toolLorenzo Bianconi6-2/+1105
Introduce xdp_features tool in order to test XDP features supported by the NIC and match them against advertised ones. In order to test supported/advertised XDP features, xdp_features must run on the Device Under Test (DUT) and on a Tester device. xdp_features opens a control TCP channel between DUT and Tester devices to send control commands from Tester to the DUT and a UDP data channel where the Tester sends UDP 'echo' packets and the DUT is expected to reply back with the same packet. DUT installs multiple XDP programs on the NIC to test XDP capabilities and reports back to the Tester some XDP stats. Currently xdp_features supports the following XDP features: - XDP_DROP - XDP_ABORTED - XDP_PASS - XDP_TX - XDP_REDIRECT - XDP_NDO_XMIT Co-developed-by: Kumar Kartikeya Dwivedi <[email protected]> Signed-off-by: Kumar Kartikeya Dwivedi <[email protected]> Signed-off-by: Lorenzo Bianconi <[email protected]> Acked-by: Stanislav Fomichev <[email protected]> Link: https://lore.kernel.org/r/7c1af8e7e6ef0614cf32fa9e6bdaa2d8d605f859.1675245258.git.lorenzo@kernel.org Signed-off-by: Alexei Starovoitov <[email protected]>
