Are you sure you are dealing\n> with a fuse based ntfs or with the kernel based implementation?\n> \n\nOn Ubuntu, ntfs3 is available as a kernel module, so \nhas_kernel_support() in tst_supported_fs_types.c probes the kernel\nmount, succeeds, and returns TST_FS_KERNEL immediately — never \nreaching the FUSE detection path. As a result, the existing \"fuse\"\nskip doesn't fire even though safe_macros always mounts ntfs via\nFUSE anyway. \n \nI investigated fixing this in the library by consulting possibly_fuse() \nin has_kernel_support() to fall through to FUSE detection when\nsafe_macros would use FUSE regardless. However, possibly_fuse() covers\nboth \"ntfs\" and \"exfat\", but safe_macros treats them differently — \nntfs always uses FUSE, while exfat tries the kernel driver first and\nfalls back to FUSE only on failure. The fix would incorrectly mark \nexfat as FUSE-based on systems with kernel exfat support, causing \nspurious skips in tests that skip \"fuse\".\n \nGiven that, I think the test-level fix is appropriate here. ntfs-3g \nreturns EINVAL for any unhandled ioctl, so skipping ntfs in file_attr05\nis correct and consistent with how \"fuse\" is already handled in the \nsame skip list.\n\n\n-matt","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","ltp@lists.linux.it"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","ltp@picard.linux.it"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (1024-bit key;\n unprotected) header.d=lists.linux.it header.i=@lists.linux.it\n header.a=rsa-sha256 header.s=picard header.b=KK3Dt01I;\n\tdkim=fail reason=\"signature verification failed\" (2048-bit key;\n unprotected) header.d=Nvidia.com header.i=@Nvidia.com header.a=rsa-sha256\n header.s=selector2 header.b=Xw916UI2;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.linux.it\n (client-ip=213.254.12.146;

The ntfs driver in kernel is the old\nread-only one and ntfs3 is the new read-write kernel driver.\n\nWhat we can do in the library is to fix the ntfs driver to be always\nhandled by fuse and add ntfs3 that is the read-write kernel driver. With\nthat we will fix this test but also enable more coverage.\n\nThis works for me:\n\ndiff --git a/lib/tst_mkfs.c b/lib/tst_mkfs.c\nindex c619a373d..961ffc091 100644\n--- a/lib/tst_mkfs.c\n+++ b/lib/tst_mkfs.c\n@@ -50,6 +50,9 @@ void tst_mkfs_(const char *file, const int lineno, void (cleanup_fn)(void),\n return;\n }\n\n+ if (!strcmp(fs_type, \"ntfs3\"))\n+ fs_type = \"ntfs\";\n+\n snprintf(mkfs, sizeof(mkfs), \"mkfs.%s\", fs_type);\n\n if (fs_opts) {\ndiff --git a/lib/tst_supported_fs_types.c b/lib/tst_supported_fs_types.c\nindex 0c8c8dc50..d3020fc48 100644\n--- a/lib/tst_supported_fs_types.c\n+++ b/lib/tst_supported_fs_types.c\n@@ -30,6 +30,7 @@ static const char *const fs_type_whitelist[] = {\n \"vfat\",\n \"exfat\",\n \"ntfs\",\n+ \"ntfs3\",\n \"tmpfs\",\n NULL\n };\n@@ -51,6 +52,9 @@ static int has_mkfs(const char *fs_type)\n return 1;\n }\n\n+ if (!strcmp(fs_type, \"ntfs3\"))\n+ fs_type = \"ntfs\";\n+\n sprintf(buf, \"mkfs.%s >/dev/null 2>&1\", fs_type);\n\n ret = tst_system(buf);\n@@ -87,6 +91,9 @@ static enum tst_fs_impl has_kernel_support(const char *fs_type)\n char template[PATH_MAX];\n int ret;\n\n+ if (!strcmp(fs_type, \"ntfs\"))\n+ goto check_fuse;\n+\n snprintf(template, sizeof(template), \"%s/mountXXXXXX\", tmpdir);\n if (!mkdtemp(template))\n tst_brk(TBROK | TERRNO, \"mkdtemp(%s) failed\", template);\n@@ -102,6 +109,7 @@ static enum tst_fs_impl has_kernel_support(const char *fs_type)\n\n SAFE_RMDIR(template);\n\n+check_fuse:\n if (tst_fs_in_skiplist(fs_type, fs_type_fuse_blacklist)) {\n tst_res(TINFO, \"Skipping %s because of FUSE blacklist\", fs_type);\n return TST_FS_UNSUPPORTED;","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","ltp@lists.linux.it"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","ltp@picard.linux.it"],"Authentication-Results":["legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.linux.it\n (client-ip=213.254.12.146;

Normal run with ntfs3 loaded — ntfs correctly detected as FUSE-based\n and skipped, ntfs3 runs via kernel driver and passes (6/6):\n\n tst_supported_fs_types.c: TINFO: FUSE does support ntfs\n tst_supported_fs_types.c: TINFO: Skipping FUSE based ntfs as requested by the test\n tst_supported_fs_types.c: TINFO: Kernel supports ntfs3\n tst_supported_fs_types.c: TINFO: mkfs.ntfs does exist\n ...\n tst_test.c: TINFO: === Testing on ntfs3 ===\n file_attr05.c: TPASS: file_setattr(...) : EOPNOTSUPP (95)\n\n2. Normal run with ntfs3 not loaded — same result, kernel autoloads\n ntfs3 on mount (6/6).\n\n3. Force ntfs3 — formats with mkfs.ntfs, mounts as ntfs3, passes.\n\n4. Force ntfs — mounts via FUSE, returns EINVAL as expected, confirming\n the \"fuse\" skip is what protects the normal run.\n\nAre you planning to send this as a formal patch? Happy to defer to\nyou since it's a cleaner fix at the library level, but want to make\nsure it doesn't fall through the cracks.\n\n-matt","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","ltp@lists.linux.it"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","ltp@picard.linux.it"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (1024-bit key;\n unprotected) header.d=lists.linux.it header.i=@lists.linux.it\n header.a=rsa-sha256 header.s=picard header.b=l/wlpp0A;\n\tdkim=fail reason=\"signature verification failed\" (2048-bit key;\n unprotected) header.d=Nvidia.com header.i=@Nvidia.com header.a=rsa-sha256\n header.s=selector2 header.b=kNG1MkuO;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.linux.it\n (client-ip=2001:1418:10:5::2;
