2022-10-25selftests/timens: add a test for vfork+exitAndrei Vagin1-0/+1
* check that a child process is in parent's time namespace after vfork. * check that a child process is in the target namespace after exec. Output on success: 1..4 ok 1 parent before vfork ok 2 child after exec ok 3 wait for child ok 4 parent after vfork # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:0 error:0 Signed-off-by: Andrei Vagin <[email protected]> Signed-off-by: Kees Cook <[email protected]> Link: https://lore.kernel.org/r/[email protected]

2020-01-14selftests/timens: Add Time Namespace test for supported clocksDmitry Safonov1-0/+1
A test to check that all supported clocks work on host and inside a new time namespace. Use both ways to get time: through VDSO and by entering the kernel with implicit syscall. Introduce a new timens directory in selftests framework for the 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 0 Output with lack of permissions: 1..10 not ok 1 # SKIP need to run as root Output without support of time namespaces: 1..10 not ok 1 # SKIP Time namespaces are not supported Co-developed-by: Andrei Vagin <[email protected]> Signed-off-by: Andrei Vagin <[email protected]> Signed-off-by: Dmitry Safonov <[email protected]> Signed-off-by: Thomas Gleixner <[email protected]> Link: https://lore.kernel.org/r/[email protected]
