From: Filipe Manana <[email protected]> The previous patches added support for operations to set and get xattrs on regular files and directories, this patch just adds one operation to delete xattrs on files and directories.
Signed-off-by: Filipe Manana <[email protected]> --- 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. ltp/fsstress.c | 53 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) diff --git a/ltp/fsstress.c b/ltp/fsstress.c index 53e6a847..1694c5a2 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); @@ -228,6 +230,7 @@ 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 }, @@ -3066,6 +3069,56 @@ creat_f(int opno, long r) } void +delfattr_f(int opno, long r) +{ + int fd; + fent_t *fep; + int e; + pathname_t f; + int v; + char name[XATTR_NAME_BUF_SIZE]; + int xattr_num; + DIR *dir; + + 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); + free_pathname(&f); + return; + } + fd = open_file_or_dir(&f, O_WRONLY, &dir); + e = fd < 0 ? errno : 0; + if (fd < 0) { + if (v) + printf("%d/%d: delfattr - open %s failed %d\n", + procid, opno, f.path, e); + free_pathname(&f); + return; + } + check_cwd(); + + /* + * If the file/dir has xattrs, pick one randomly, otherwise attempt to + * remove a xattr that doesn't exist (fremovexattr 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 = fremovexattr(fd, name) < 0 ? errno : 0; + if (v) + printf("%d/%d: delfattr file %s name %s %d\n", + procid, opno, f.path, name, e); + free_pathname(&f); + close_file_or_dir(fd, dir); +} + +void dread_f(int opno, long r) { int64_t align; -- 2.11.0
