2022-03-01selftests/powerpc/pmu/: Add interface test for mmcr0_pmcjce fieldAthira Rajeev3-1/+61
The testcase uses event code 0x500fa ("instructions") to verify the PMCjCE bit setting in Monitor Mode Control Register 0 (MMCR0). This bit is expected to be set in MMCR0 when using Performance Monitor Counter 5 (PMC5). Checks if perf interface sets this bit correctly.

2022-03-01selftests/powerpc/pmu/: Add interface test for mmcr0_cc56run fieldAthira Rajeev3-1/+61
The testcase uses event code 0x500fa ("instructions") to check the CC56RUN bit setting in Monitor Mode Control Register 0(MMCR0). In ISA v3.1 platform, this bit is expected to be set in MMCR0 when using Performance Monitor Counter 5 and 6 (PMC5 and PMC6). Verify this is done correctly by perf interface. CC56RUN bit makes PMC5 and PMC6 count regardless of the run latch state. This bit is set in power10 since PMC5 and PMC6 is used in power10 for counting instructions and cycles. Hence added a check to skip this test in other platforms Signed-off-by: Athira Rajeev <[email protected]> [mpe: Add error checking, drop GET_MMCR_FIELD, add to .gitignore] Signed-off-by: Michael Ellerman <[email protected]> Link: https://lore.kernel.org/r/[email protected]
2022-03-01selftests/powerpc/pmu/: Add interface test for mmcr0 exception bitsAthira Rajeev3-1/+63
The testcase uses "instructions" event to verify two bits(PMAE and PMAO) in Monitor Mode Control Register 0 (MMCR0). At the time of interrupt, pmae bit ( which enables performance monitor exception ) is expected to be cleared and pmao (which indicates performance monitor alert) bit is expected to be set in MMCR0. And testcases handles these checks.

2022-02-25selftests/rtc: continuously read RTC in a loop for 30sMateusz Jończyk2-1/+67
Some problems with reading the RTC time may happen rarely, for example while the RTC is updating. So read the RTC many times to catch these problems. For example, a previous attempt for my commit ea6fa4961aab ("rtc: mc146818-lib: fix RTC presence check") was incorrect and would have triggered this selftest. To avoid the risk of damaging the hardware, wait 11ms before consecutive reads. In rtc_time_to_timestamp I copied values manually instead of casting - just to be on the safe side. The 11ms wait period was chosen so that it is not a divisor of 1000ms.

2022-02-25KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3Mark Brown3-2/+13
The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

2022-02-23selftests: futex: Add the uapi headers include variableMuhammad Usama Anjum1-3/+2
Out of tree build of this test fails if relative path of the output directory is specified. KBUILD_OUTPUT also doesn't point to the correct directory when relative path is used. Thus out of tree builds fail. Remove the un-needed include paths and use KHDR_INCLUDES to correctly reach the headers.

2022-02-23selftests: Correct the headers install pathMuhammad Usama Anjum1-1/+1
uapi headers should be installed at the top of the object tree, "<obj_tree>/usr/include". There is no need for kernel headers to be present at kselftest build directory, "<obj_tree>/kselftest/usr/ include" as well. This duplication can be avoided by correctly specifying the INSTALL_HDR_PATH. Signed-off-by: Muhammad Usama Anjum <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
2022-02-23selftests: Add and export a kernel uapi headers pathMuhammad Usama Anjum1-0/+4
Kernel uapi headers can be present at different paths depending upon how the build was invoked. It becomes impossible for the tests to include the correct headers directory. Set and export KHDR_INCLUDES variable to make it possible for sub make files to include the header files.

2022-02-23selftests: set the BUILD variable to absolute pathMuhammad Usama Anjum1-9/+17
The build of kselftests fails if relative path is specified through KBUILD_OUTPUT or O=<path> method. BUILD variable is used to determine the path of the output objects. When make is run from other directories with relative paths, the exact path of the build objects is ambiguous and build fails. make[1]: Entering directory '/home/usama/repos/kernel/linux_mainline2/tools/testing/selftests/alsa' gcc mixer-test.c -L/usr/lib/x86_64-linux-gnu -lasound -o build/kselftest/alsa/mixer-test /usr/bin/ld: cannot open output file build/kselftest/alsa/mixer-test Set the BUILD variable to the absolute path of the output directory.

2022-02-23selftests: futex: set DEFAULT_INSTALL_HDR_PATHMuhammad Usama Anjum1-0/+1
If only futex selftest is compiled, uapi header files are copied to the selftests/futex/functional directory. This copy isn't needed. Set the DEFAULT_INSTALL_HDR_PATH variable to 1 to use the default header install path only. This removes extra copy of header file.

2022-02-23selftests/kselftest/runner.sh: Pass optional command parameters in environmentCristian Marussi1-1/+29
Some testcases allow for optional commandline parameters but as of now there is now way to provide such arguments to the runner script. Add support to retrieve such optional command parameters fron environment variables named so as to include the all-uppercase test executable name, sanitized substituting any non-acceptable varname characters with "_", following the pattern: KSELFTEST_<UPPERCASE_SANITIZED_TEST_NAME>_ARGS="options" Optional command parameters support is not available if 'tr' is not installed on the test system.

2022-02-23livepatch: Skip livepatch tests if ftrace cannot be configuredDavid Vernet2-4/+21
livepatch has a set of selftests that are used to validate the behavior of the livepatching subsystem. One of the testcases in the livepatch testsuite is test-ftrace.sh, which among other things, validates that livepatching gracefully fails when ftrace is disabled. In the event that ftrace cannot be disabled using 'sysctl kernel.ftrace_enabled=0', the test will fail later due to it unexpectedly successfully loading the test_klp_livepatch module. While the livepatch selftests are careful to remove any of the livepatch test modules between testcases to avoid this situation, ftrace may still fail to be disabled if another trace is active on the system that was enabled with FTRACE_OPS_FL_PERMANENT. For example, any active BPF programs that use trampolines will cause this test to fail due to the trampoline being implemented with register_ftrace_direct(). The following is an example of such a trace: tcp_drop (1) R I D tramp: ftrace_regs_caller+0x0/0x58 (call_direct_funcs+0x0/0x30) direct-->bpf_trampoline_6442550536_0+0x0/0x1000 In order to make the test more resilient to system state that is out of its control, this patch updates set_ftrace_enabled() to detect sysctl failures, and skip the testrun when appropriate.

Add option to shift the clock by a specified number of nanoseconds. The new argument -n will specify the number of nanoseconds to add to the ptp clock. Since the API doesn't support negative shifts those needs to be calculated by subtracting full seconds and adding a nanosecond offset.

This test tries to pass a PTR_TO_BTF_ID_OR_NULL to the release function, which would trigger a out of bounds access without the fix in commit 45ce4b4f9009 ("bpf: Fix crash due to out of bounds access into reg2btf_ids.") but after the fix, it should only index using base_type(reg->type), which should be less than __BPF_REG_TYPE_MAX, and also not permit any type flags to be set for the reg->type.
