[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.

POSSIBLE BUG: selftests/net/fcnal-test.sh: [FAIL] in vrf "bind - ns-B IPv6 LLA" test

Maybe we have a regression? My knowledge of fcnal-test.sh isn't sufficient to build a smaller reproducer. Guillaume said in January he could help with the net/fcnal-test.sh, but I was doing the other things in the meantime.

file removal issue in tools/testing/selftests/powerpc/mm/tlbie_test.c

by Colin King (gmail)

Hi, Static analysis with cppcheck has found an issue in the following commit: commit 047e6575aec71d75b765c22111820c4776cd1c43 Author: Aneesh Kumar K.V <aneesh.kumar(a)linux.ibm.com> Date: Tue Sep 24 09:22:53 2019 +0530 powerpc/mm: Fixup tlbie vs mtpidr/mtlpidr ordering issue on POWER9 The issue in tools/testing/selftests/powerpc/mm/tlbie_test.c in end_verification_log() is as follows: static inline void end_verification_log(unsigned int tid, unsigned nr_anamolies) { FILE *f = fp[tid]; char logfile[30]; char path[LOGDIR_NAME_SIZE + 30]; char separator[] = "/"; fclose(f); if (nr_anamolies == 0) { remove(path); return; } .... etc in the case where nr_anamolies is zero the remove(path) call is using an uninitialized path, this potentially could contain uninitialized garbage on the stack (and if one is unlucky enough it may be a valid filename that one does not want to be removed). Not sure what the original intention was, but this code looks incorrect to me. Colin

[PATCH] selftests: lib.mk: fix out-of-tree builds

Since commit ("selftests: error out if kernel header files are not yet built") got merged, the kselftest build correctly because the KBUILD_OUTPUT isn't set when building out-of-tree and specifying 'O=' This is the error message that pops up. make --silent --keep-going --jobs=32 O=/home/anders/.cache/tuxmake/builds/1482/build INSTALL_PATH=/home/anders/.cache/tuxmake/builds/1482/build/kselftest_install ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- V=1 CROSS_COMPILE_COMPAT=arm-linux-gnueabihf- kselftest-install make[3]: Entering directory '/home/anders/src/kernel/next/tools/testing/selftests/alsa' -e [1;31merror[0m: missing kernel header files.
