Create a file on a filesystem and add an xattr to it # 2. Unmount the filesystem, and mount it -o noxattr # 3. Verify that the xattr cannot be read and new files # cannot have xattrs set on them. # 4. Unmount and mount the filesystem normally # 5. Verify that xattrs can be set and accessed again # function cleanup { log_must rm $TESTDIR/myfile.$$ } log_assert "The noxattr mount option functions as expected" log_onexit cleanup zfs set 2>&1 | grep xattr > /dev/null if [ $? -ne 0 ] then log_unsupported "noxattr mount option not supported on this release." fi log_must touch $TESTDIR/myfile.$$ create_xattr $TESTDIR/myfile.$$ passwd /etc/passwd log_must umount $TESTDIR log_must zfs mount -o noxattr $TESTPOOL/$TESTFS # check that we can't perform xattr operations log_mustnot eval "runat $TESTDIR/myfile.$$ cat passwd > /dev/null 2>&1" log_mustnot eval "runat $TESTDIR/myfile.$$ rm passwd > /dev/null 2>&1" log_mustnot eval "runat $TESTDIR/myfile.$$ cp /etc/passwd . > /dev/null 2>&1" log_must touch $TESTDIR/new.$$ log_mustnot eval "runat $TESTDIR/new.$$ cp /etc/passwd . > /dev/null 2>&1" log_mustnot eval "runat $TESTDIR/new.$$ rm passwd > /dev/null 2>&1" # now mount the filesystem again as normal log_must umount $TESTDIR log_must zfs mount $TESTPOOL/$TESTFS # we should still have an xattr on the first file verify_xattr $TESTDIR/myfile.$$ passwd /etc/passwd # there should be no xattr on the file we created while the fs was mounted # -o noxattr log_mustnot eval "runat $TESTDIR/new.$$ cat passwd > /dev/null 2>&1" create_xattr $TESTDIR/new.$$ passwd /etc/passwd log_pass "The noxattr mount option functions as expected"
