From a50b2ab170ed12c950a621f8f29f1619850286fb Mon Sep 17 00:00:00 2001 From: Nikolaus Rath Date: Sun, 6 Nov 2016 20:59:55 -0800 Subject: Added test for fchmod At the moment this test fails (cf. issue #62). If that gets fixed in the kernel, this test can be activated conditionally. --- test/Makefile.am | 3 +- test/test_setattr.c | 184 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 186 insertions(+), 1 deletion(-) create mode 100644 test/test_setattr.c (limited to 'test') diff --git a/test/Makefile.am b/test/Makefile.am index 0f2199f..9eb0a73 100644 --- a/test/Makefile.am +++ b/test/Makefile.am @@ -1,6 +1,7 @@ ## Process this file with automake to produce Makefile.in AM_CPPFLAGS = -I$(top_srcdir)/include -D_REENTRANT -noinst_PROGRAMS = test test_write_cache +noinst_PROGRAMS = test test_write_cache test_setattr test_write_cache_LDADD = ../lib/libfuse3.la +test_setattr_LDADD = ../lib/libfuse3.la diff --git a/test/test_setattr.c b/test/test_setattr.c new file mode 100644 index 0000000..1eef66a --- /dev/null +++ b/test/test_setattr.c @@ -0,0 +1,184 @@ +/* + FUSE: Filesystem in Userspace + Copyright (C) 2016 Nikolaus Rath + + This program can be distributed under the terms of the GNU GPL. + See the file COPYING. +*/ + + +#define FUSE_USE_VERSION 30 + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#define FILE_INO 2 +#define FILE_NAME "truncate_me" + +static int got_fh; +static mode_t file_mode = S_IFREG | 0644; + +static int tfs_stat(fuse_ino_t ino, struct stat *stbuf) { + stbuf->st_ino = ino; + if (ino == FUSE_ROOT_ID) { + stbuf->st_mode = S_IFDIR | 0755; + stbuf->st_nlink = 1; + } + + else if (ino == FILE_INO) { + stbuf->st_mode = file_mode; + stbuf->st_nlink = 1; + stbuf->st_size = 0; + } + + else + return -1; + + return 0; +} + +static void tfs_lookup(fuse_req_t req, fuse_ino_t parent, + const char *name) { + struct fuse_entry_param e; + memset(&e, 0, sizeof(e)); + + if (parent != FUSE_ROOT_ID) + goto err_out; + else if (strcmp(name, FILE_NAME) == 0) + e.ino = FILE_INO; + else + goto err_out; + + if (tfs_stat(e.ino, &e.attr) != 0) + goto err_out; + fuse_reply_entry(req, &e); + return; + +err_out: + fuse_reply_err(req, ENOENT); +} + +static void tfs_getattr(fuse_req_t req, fuse_ino_t ino, + struct fuse_file_info *fi) { + struct stat stbuf; + + (void) fi; + + memset(&stbuf, 0, sizeof(stbuf)); + if (tfs_stat(ino, &stbuf) != 0) + fuse_reply_err(req, ENOENT); + else + fuse_reply_attr(req, &stbuf, 5); +} + +static void tfs_open(fuse_req_t req, fuse_ino_t ino, + struct fuse_file_info *fi) { + if (ino == FUSE_ROOT_ID) + fuse_reply_err(req, EISDIR); + else { + assert(ino == FILE_INO); + fi->fh = FILE_INO; + fuse_reply_open(req, fi); + } +} + +static void tfs_setattr (fuse_req_t req, fuse_ino_t ino, struct stat *attr, + int to_set, struct fuse_file_info *fi) { + if(ino != FILE_INO || + !(to_set & FUSE_SET_ATTR_MODE)) { + fuse_reply_err(req, EINVAL); + return; + } + + if(fi == NULL) + fprintf(stderr, "setattr with fi == NULL\n"); + else if (fi->fh != FILE_INO) + fprintf(stderr, "setattr with wrong fi->fh\n"); + else { + fprintf(stderr, "setattr ok\n"); + got_fh = 1; + file_mode = attr->st_mode; + } + + tfs_getattr(req, ino, fi); +} + +static struct fuse_lowlevel_ops tfs_oper = { + .lookup = tfs_lookup, + .getattr = tfs_getattr, + .open = tfs_open, + .setattr = tfs_setattr, +}; + +static void* run_fs(void *data) { + struct fuse_session *se = (struct fuse_session*) data; + assert(fuse_session_loop(se) == 0); + return NULL; +} + +static void test_fs(char *mountpoint) { + char fname[PATH_MAX]; + int fd; + + assert(snprintf(fname, PATH_MAX, "%s/" FILE_NAME, + mountpoint) > 0); + fd = open(fname, O_WRONLY); + if (fd == -1) { + perror(fname); + assert(0); + } + + assert(fchmod(fd, 0600) == 0); + close(fd); +} + +int main(int argc, char *argv[]) { + struct fuse_args args = FUSE_ARGS_INIT(argc, argv); + struct fuse_session *se; + struct fuse_cmdline_opts fuse_opts; + pthread_t fs_thread; + + assert(fuse_parse_cmdline(&args, &fuse_opts) == 0); + assert(fuse_opt_add_arg(&args, "-oauto_unmount") == 0); + se = fuse_session_new(&args, &tfs_oper, + sizeof(tfs_oper), NULL); + assert (se != NULL); + assert(fuse_set_signal_handlers(se) == 0); + assert(fuse_session_mount(se, fuse_opts.mountpoint) == 0); + + /* Start file-system thread */ + assert(pthread_create(&fs_thread, NULL, run_fs, (void *)se) == 0); + + /* Do test */ + test_fs(fuse_opts.mountpoint); + + /* Stop file system */ + assert(pthread_cancel(fs_thread) == 0); + + fuse_session_unmount(se); + assert(got_fh == 1); + fuse_remove_signal_handlers(se); + fuse_session_destroy(se); + + printf("Test completed successfully.\n"); + return 0; +} + + +/** + * Local Variables: + * mode: c + * indent-tabs-mode: nil + * c-basic-offset: 4 + * End: + */ -- cgit v1.2.3
