LTP syscalls memfd_create04 failed on arm64 devices. Test PASS on arm, i386 and x86_64.
We are bisecting this failure on arm64.
Test case failed log, memfd_create04.c:68: INFO: Attempt to create file using 64kB huge page size memfd_create04.c:76: FAIL: memfd_create() failed unexpectedly: ENOENT (2)
Strace output: memfd_create("tfile", MFD_HUGETLB|0x40000000) = -1 ENOENT (No such file or directory)
Test case Description,
/* * Test: Validating memfd_create() with MFD_HUGETLB and MFD_HUGE_x flags. * * Test cases: Attempt to create files in the hugetlbfs filesystem using * different huge page sizes. * * Test logic: memfd_create() should return non-negative value (fd) * if the system supports that particular huge page size. * On success, fd is returned. * On failure, -1 is returned with ENODEV error. */
Test code snippet: <> check_hugepage_support(&tflag); tst_res(TINFO, "Attempt to create file using %s huge page size", tflag.h_size);
fd = sys_memfd_create("tfile", MFD_HUGETLB | tflag.flag); if (fd < 0) { if (errno == tflag.exp_err) tst_res(TPASS, "Test failed as expected\n"); else tst_brk(TFAIL | TERRNO, "memfd_create() failed unexpectedly"); return; } <>
Steps to reproduce: - cd /opt/ltp/testcases/bin/ - ./memfd_create04
