2023-02-09selftests/powerpc: Parse long/unsigned long value safelyBenjamin Gray
Often a file is expected to hold an integral value. Existing functions will use a C stdlib function like atoi or strtol to parse the file. These operations are error prone, with complicated error conditions (atoi returns 0 if not a number, and is undefined behaviour if not in range. strtol returns 0 if not a number, and LONG_MIN/MAX if not in range + sets errno to ERANGE).

2023-02-08KVM: selftests: Clean up misnomers in xen_shinfo_testMichal Luczaj
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 Baerts
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: Don't require FA64 for streaming SVE+ZA testsMark Brown
During early development a dependedncy was added on having FA64 available so we could use the full FPSIMD register set in the signal handler which got copied over into the SSVE+ZA registers test case. Subsequently the ABI was finialised so the handler is run with streaming mode disabled meaning this is redundant but the dependency was never removed, do so now.

2023-02-07kselftest/arm64: Copy whole EXTRA contextMark Brown
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 Machata
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 Brown
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.
