Tiezhu Yang 4c004ed952 selftests/clone3: Fix broken test under !CONFIG_TIME_NS ... commit fc7f04dc23 upstream. When execute the following command to test clone3 under !CONFIG_TIME_NS: # make headers && cd tools/testing/selftests/clone3 && make && ./clone3 we can see the following error info: # [7538] Trying clone3() with flags 0x80 (size 0) # Invalid argument - Failed to create new process # [7538] clone3() with flags says: -22 expected 0 not ok 18 [7538] Result (-22) is different than expected (0) ... # Totals: pass:18 fail:1 xfail:0 xpass:0 skip:0 error:0 This is because if CONFIG_TIME_NS is not set, but the flag CLONE_NEWTIME (0x80) is used to clone a time namespace, it will return -EINVAL in copy_time_ns(). If kernel does not support CONFIG_TIME_NS, /proc/self/ns/time will be not exist, and then we should skip clone3() test with CLONE_NEWTIME. With this patch under !CONFIG_TIME_NS: # make headers && cd tools/testing/selftests/clone3 && make && ./clone3 ... # Time namespaces are not supported ok 18 # SKIP Skipping clone3() with CLONE_NEWTIME ... # Totals: pass:18 fail:0 xfail:0 xpass:0 skip:1 error:0 Link: https://lkml.kernel.org/r/1689066814-13295-1-git-send-email-yangtiezhu@loongson.cn Fixes: 515bddf0ec ("selftests/clone3: test clone3 with CLONE_NEWTIME") Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Suggested-by: Thomas Gleixner <tglx@linutronix.de> Cc: Christian Brauner <brauner@kernel.org> Cc: Shuah Khan <shuah@kernel.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-11-28 17:20:05 +00:00
