selftests/timens: Add Time Namespace test for supported clocksA test to check that all supported clocks work on host and insidea new time namespace. Use both ways to get time: through VDSO andby entering the kernel with implicit syscall.Introduce a new timens directory in selftests framework forthe next timens tests.Output on success: 1..10 ok 1 Passed for CLOCK_BOOTTIME (syscall) ok 2 Passed for CLOCK_BOOTTIME (vdso) ok 3 Passed for CLOCK_BOOTTIME_ALARM (syscall) ok 4 Passed for CLOCK_BOOTTIME_ALARM (vdso) ok 5 Passed for CLOCK_MONOTONIC (syscall) ok 6 Passed for CLOCK_MONOTONIC (vdso) ok 7 Passed for CLOCK_MONOTONIC_COARSE (syscall) ok 8 Passed for CLOCK_MONOTONIC_COARSE (vdso) ok 9 Passed for CLOCK_MONOTONIC_RAW (syscall) ok 10 Passed for CLOCK_MONOTONIC_RAW (vdso) # Pass 10 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0Output with lack of permissions: 1..10 not ok 1 # SKIP need to run as rootOutput without support of time namespaces: 1..10 not ok 1 # SKIP Time namespaces are not supportedCo-developed-by: Andrei Vagin Signed-off-by: Andrei Vagin Signed-off-by: Dmitry Safonov Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20191112012724.250792-29-dima@arista.com List of files: /linux-6.15/tools/testing/selftests/timens/config
