[PATCH] selftests/cgroup: allow running a specific test with test_memcontrol

by Yosry Ahmed

It is handy during testing and/or debugging to be able to run a single test from test_memcontrol. Allow passing in a test name through a command line argument (e.g. ./test_memcontrol -t test_memcg_recharge).

[PATCH v4 0/4] Check if FIPS mode is enabled when running selftests

by Magali Lemes

Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. Changes in v4: - Remove extra newline. - Add R-b tag. Changes in v3: - Add new commit to allow skipping test directly from test setup. - No need to initialize static variable to zero. - Skip tests during test setup only. - Use the constructor attribute to set fips_enabled before entering main(). Changes in v2: - Add R-b tags. - Put fips_non_compliant into the variants. - Turn fips_enabled into a static global variable. - Read /proc/sys/crypto/fips_enabled only once at main(). v1: https://lore.kernel.org/netdev/20230607174302.19542-1-magali.lemes@canonica… v2: https://lore.kernel.org/netdev/20230609164324.497813-1-magali.lemes@canonic… v3: https://lore.kernel.org/netdev/20230612125107.73795-1-magali.lemes@canonica… Magali Lemes (4): selftests/harness: allow tests to be skipped during setup selftests: net: tls: check if FIPS mode is enabled selftests: net: vrf-xfrm-tests: change authentication and encryption algos selftests: net: fcnal-test: check if FIPS mode is enabled tools/testing/selftests/kselftest_harness.h | 6 ++-- tools/testing/selftests/net/fcnal-test.sh | 27 +++++++++++----- tools/testing/selftests/net/tls.c | 24 +++++++++++++- tools/testing/selftests/net/vrf-xfrm-tests.sh | 32 +++++++++---------- 4 files changed, 61 insertions(+), 28 deletions(-) -- 2.34.1

[PATCH] kselftest/alsa: Increase kselftest timeout

by Nícolas F. R. A. Prado

The default timeout for kselftests is 45 seconds, but pcm-test can take longer than that to run depending on the number of PCMs present on a device. As a data point, running pcm-test on mt8192-asurada-spherion takes about 1m15s. Set the timeout to 10 minutes, which should give enough slack to run the test even on devices with many PCMs. Signed-off-by: Nícolas F. R. A.

[PATCH] selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET

by Alex Maftei

Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful. This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value. Fixes: 568ebc5985f5 ("ptp: add the PTP_SYS_OFFSET ioctl to the testptp program") Fixes: 4ec54f95736f ("ptp: Fix compiler warnings in the testptp utility") Fixes: 6ab0e475f1f3 ("Documentation: fix misc. warnings") Signed-off-by: Alex Maftei <alex.maftei(a)amd.com> --- tools/testing/selftests/ptp/testptp.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/tools/testing/selftests/ptp/testptp.c b/tools/testing/selftests/ptp/testptp.c index 198ad5f32187..cfa9562f3cd8 100644 --- a/tools/testing/selftests/ptp/testptp.c +++ b/tools/testing/selftests/ptp/testptp.c @@ -502,11 +502,11 @@ int main(int argc, char *argv[]) interval = t2 - t1; offset = (t2 + t1) / 2 - tp; - printf("system time: %lld.%u\n", + printf("system time: %lld.%09u\n", (pct+2*i)->sec, (pct+2*i)->nsec); - printf("phc time: %lld.%u\n", + printf("phc time: %lld.%09u\n", (pct+2*i+1)->sec, (pct+2*i+1)->nsec); - printf("system time: %lld.%u\n", + printf("system time: %lld.%09u\n", (pct+2*i+2)->sec, (pct+2*i+2)->nsec); printf("system/phc clock time offset is %" PRId64 " ns\n" "system clock time delay is %" PRId64 " ns\n", -- 2.28.0

[PATCH] selftests/mm: Fix cross compilation with LLVM

by Mark Brown

Currently the MM selftests attempt to work out the target architecture by using CROSS_COMPILE or otherwise querying the host machine, storing the target architecture in a variable called MACHINE rather than the usual ARCH though as far as I can tell (including for x86_64) the value is the same as we would use for architecture. When cross compiling with LLVM we don't need a CROSS_COMPILE as LLVM can support many target architectures in a single build so this logic does not work, CROSS_COMPILE is not set and we end up selecting tests for the host rather than target architecture. Fix this by using the more standard ARCH to describe the architecture, taking it from the environment if specified.
