Signed-off-by: Filipe Manana --- V2: Use a different name for the operation (delfattr) and make use of the helper functions for opening and closing files or directories, introduced in the first patch of this series. V3: Simplified implementation to not need to open a file descriptor and use a path string instead. ltp/fsstress.c | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/ltp/fsstress.c b/ltp/fsstress.c index 7c924e01..0bbb72d9 100644 --- a/ltp/fsstress.c +++ b/ltp/fsstress.c @@ -60,6 +60,7 @@ typedef enum { OP_COPYRANGE, OP_CREAT, OP_DEDUPERANGE, + OP_DELFATTR, OP_DREAD, OP_DWRITE, OP_FALLOCATE, @@ -175,6 +176,7 @@ void clonerange_f(int, long); void copyrange_f(int, long); void creat_f(int, long); void deduperange_f(int, long); +void delfattr_f(int, long); void dread_f(int, long); void dwrite_f(int, long); void fallocate_f(int, long); @@ -230,6 +232,7 @@ opdesc_t ops[] = { { OP_COPYRANGE, "copyrange", copyrange_f, 4, 1 }, { OP_CREAT, "creat", creat_f, 4, 1 }, { OP_DEDUPERANGE, "deduperange", deduperange_f, 4, 1}, + { OP_DELFATTR, "delfattr", delfattr_f, 2, 1 }, { OP_DREAD, "dread", dread_f, 4, 0 }, { OP_DWRITE, "dwrite", dwrite_f, 4, 1 }, { OP_FALLOCATE, "fallocate", fallocate_f, 1, 1 }, @@ -3062,6 +3065,44 @@ creat_f(int opno, long r) } void +delfattr_f(int opno, long r) +{ + fent_t *fep; + int e; + pathname_t f; + int v; + char name[XATTR_NAME_BUF_SIZE]; + int xattr_num; + + init_pathname(&f); + if (!get_fname(FT_REGFILE | FT_DIRm, r, &f, NULL, &fep, &v)) { + if (v) + printf("%d/%d: delfattr - no filename\n", procid, opno); + goto out; + } + check_cwd(); + + /* + * If the file/dir has xattrs, pick one randomly, otherwise attempt to + * remove a xattr that doesn't exist (removexattr should fail with + * errno set to ENOATTR (61) in this case). + */ + if (fep->xattr_counter > 0) + xattr_num = (random() % fep->xattr_counter) + 1; + else + xattr_num = 0; + + generate_xattr_name(xattr_num, name); + + e = removexattr(f.path, name) < 0 ? errno : 0; + if (v) + printf("%d/%d: delfattr file %s name %s %d\n", + procid, opno, f.path, name, e); +out: + free_pathname(&f); +} + +void dread_f(int opno, long r) { int64_t align; -- 2.11.0
