From 41ca14efaf850c3694ccc5abc18ba552ce1a3fce Mon Sep 17 00:00:00 2001 From: Shivam Chaudhary Date: Sun, 5 Jan 2025 14:22:54 +0530 Subject: [PATCH] selftests: tmpfs: Add Test-skip if not run as root Add 'ksft_exit_skip()', if not run as root, with an appropriate Warning. Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test outputs more effectively. Test logs: Before Change: - Without root error: unshare, errno 1 - With root No, output After change: - Without root TAP version 13 1..1 ok 2 # SKIP This test needs root to run! Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0 - With root TAP version 13 1..1 Link: https://lore.kernel.org/r/20250105085255.124929-2-cvam0000@gmail.com Signed-off-by: Shivam Chaudhary Signed-off-by: Shuah Khan --- tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c b/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c index b5c3ddb90942f..657b64857e826 100644 --- a/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c +++ b/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c @@ -23,10 +23,22 @@ #include #include +#include "../kselftest.h" + int main(void) { int fd; + // Setting up kselftest framework + ksft_print_header(); + ksft_set_plan(1); + + // Check if test is run as root + if (geteuid()) { + ksft_exit_skip("This test needs root to run!\n"); + return 1; + } + if (unshare(CLONE_NEWNS) == -1) { if (errno == ENOSYS || errno == EPERM) { fprintf(stderr, "error: unshare, errno %d\n", errno); -- 2.39.5
