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)
-ENOENT is what you get when hugetlbfs is not mounted, so this hints to
8fc312b32b2 mm/hugetlbfs: fix error handling when setting up mounts
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/c...
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; }
