2024-02-01selftests: mptcp: join: stop transfer when check is done (part 1)Matthieu Baerts (NGI0)
Since the "Fixes" commit mentioned below, "userspace pm" subtests of mptcp_join selftests introduced in v6.5 are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds in slow environments. Note that old versions will need commit bdbef0a6ff10 ("selftests: mptcp: add mptcp_lib_kill_wait") as well to get 'mptcp_lib_kill_wait()' helper.

2024-02-01selftests: mptcp: allow changing subtests prefixMatthieu Baerts (NGI0)
If a CI executes the same selftest multiple times with different options, all results from the same subtests will have the same title, which confuse the CI. With the same title printed in TAP, the tests are considered as the same ones. Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST env var, and have a different title. While at it, use 'basename' to remove the suffix as well instead of using an extra 'sed'.

2024-02-01selftests: mptcp: decrease BW in simult flowsMatthieu Baerts (NGI0)
When running the simult_flow selftest in slow environments -- e.g. QEmu without KVM support --, the results can be unstable. This selftest checks if the aggregated bandwidth is (almost) fully used as expected. To help improving the stability while still keeping the same validation in place, the BW and the delay are reduced to lower the pressure on the CPU.

2024-02-01selftests: mptcp: increase timeout to 30 minMatthieu Baerts (NGI0)
On very slow environments -- e.g. when QEmu is used without KVM --, mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the default timeout by 50% as it seems normal to take that long on some environments. When a debug kernel config is used, this selftest will take even longer, but that's certainly not a common test env to consider for the timeout. The Fixes tag that has been picked here is there simply to help having this patch backported to older stable versions. It is difficult to point to the exact commit that made some env reaching the timeout from time to time.

KVM sets up Hyper-V TSC page clocksource for its guests when system clocksource is 'based on TSC' (see gtod_is_based_on_tsc()), running hyperv_clock with any other clocksource leads to imminent failure.

hyperv_clocksource_tsc_page too KVM's 'gtod_is_based_on_tsc()' recognizes two clocksources: 'tsc' and 'hyperv_clocksource_tsc_page' and enables kvmclock in 'masterclock' mode when either is in use.

2024-02-01KVM: selftests: Generalize check_clocksource() from kvm_clock_testVitaly Kuznetsov
Several existing x86 selftests need to check that the underlying system clocksource is TSC or based on TSC but every test implements its own check. As a first step towards unification, extract check_clocksource() from kvm_clock_test and split it into two functions: arch-neutral 'sys_get_cur_clocksource()' and x86-specific 'sys_clocksource_is_tsc()'. Fix a couple of pre-existing issues in kvm_clock_test: memory leakage in check_clocksource() and using TEST_ASSERT() instead of TEST_REQUIRE(). The change also makes the test fail when system clocksource can't be read from sysfs.

2024-02-01selftests: bonding: Check initial stateBenjamin Poirier
The purpose of the test_LAG_cleanup() function is to check that some hardware addresses are removed from underlying devices after they have been unenslaved. The test function simply checks that those addresses are not present at the end. However, if the addresses were never added to begin with due to some error in device setup, the test function currently passes. This is a false positive since in that situation the test did not actually exercise the intended functionality. Add a check that the expected addresses are indeed present after device setup. This makes the test function more robust. I noticed this problem when running the team/dev_addr_lists.sh test on a system without support for dummy and ipv6: tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh Error: Unknown device type.

2024-01-31selftests/net: Rectify key counters checksDmitry Safonov

Rename these with _tx appendix and fix checks in verify_counters(). While at it, as the checks are now correct, introduce skip_counters_checks, which is intended for tests where it's expected that a key that was set with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance of getting used on the wire.

2024-01-31selftests/net: Argument value mismatch when calling verify_counters()Mohammad Nassiri
The end_server() function only operates in the server thread and always takes an accept socket instead of a listen socket as its input argument. To align with this, invert the boolean values used when calling verify_counters() within the end_server() function. As a result of this typo, the test didn't correctly check for the non-symmetrical scenario, where i.e. peer-A uses a key <100:200> to send data, but peer-B uses another key <105:205> to send its data.

2024-01-30KVM: selftests: Fail tests when open() fails with !ENOENTVitaly Kuznetsov
open_path_or_exit() is used for '/dev/kvm', '/dev/sev', and '/sys/module/%s/parameters/%s' and skipping test when the entry is missing is completely reasonable. Other errors, however, may indicate a real issue which is easy to miss.

2024-01-30KVM: selftests: Avoid infinite loop in hyperv_features when invtsc is missingVitaly Kuznetsov
When X86_FEATURE_INVTSC is missing, guest_test_msrs_access() was supposed to skip testing dependent Hyper-V invariant TSC feature. Unfortunately, 'continue' does not lead to that as stage is not incremented. Moreover, 'vm' allocated with vm_create_with_one_vcpu() is not freed and the test runs out of available file descriptors very quickly.

2024-01-30kselftest/seccomp: Report each expectation we assert as a KTAP testMark Brown
The seccomp benchmark test makes a number of checks on the performance it measures and logs them to the output but does so in a custom format which none of the automated test runners understand meaning that the chances that anyone is paying attention are slim. Let's additionally log each result in KTAP format so that automated systems parsing the test output will see each comparison as a test case. The original logs are left in place since they provide the actual numbers for analysis. As part of this rework the flow for the main program so that when we skip tests we still log all the tests we skip, this is because the standard KTAP headers and footers include counts of the number of expected and run tests.

2024-01-30kselftest/seccomp: Use kselftest output functions for benchmarkMark Brown
In preparation for trying to output the test results themselves in TAP format rework all the prints in the benchmark to use the kselftest output functions. The uses of system() all produce single line output so we can avoid having to deal with fully managing the child process and continue to use system() by simply printing an empty message before we invoke system(). We also leave one printf() used to complete a line of output in place.

2024-01-30selftests/livepatch: fix and refactor new dmesg message codeJoe Lawrence
The livepatching kselftests rely on comparing expected vs. observed dmesg output. After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev <agordeev@linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b2-a85c-c5cc2836eea2.ibm.com/ Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com> Acked-by: Alexander Gordeev <agordeev@linux.ibm.com> Tested-by: Marcos Paulo de Souza <mpdesouza@suse.com> Reviewed-by: Marcos Paulo de Souza <mpdesouza@suse.com> Acked-by: Miroslav Benes <mbenes@suse.cz> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

This is because when re-opening the file and parsing the header, Perf expects that any file that has more than one event has the sample ID flag set. Perf record already sets the flag in a similar way when there is more than one event, so add the same logic to evlist__new_default(). evlist__new_default() is only currently used in tests, so I don't expect this change to have any other side effects. The other tests that use it don't save and re-open the file so don't hit this issue. The session topology test has been failing on Arm big.LITTLE platforms since commit 251aa040244a3b17 ("perf parse-events: Wildcard most "numeric" events") when evlist__new_default() started opening multiple events for 'cycles'.
