The ReadOnly Bind mount tests, uses the filesystems tests from
|
|
the {LTPROOT}/testcases/kernel/fs .
|
|
|
|
EXECUTING TESTS
|
|
==================
|
|
The tests can be executed through runltp like:
|
|
|
|
./runltp -f fs_readonly
|
|
|
|
Following tests are executed when the above is invoked:
|
|
|
|
IOGEN & DOIO
|
|
|
|
|
----- iogen
|
|
|
|
|
----- doio
|
|
|
|
|
----- rwtest
|
|
|
|
|
----- growfiles
|
|
FS_INOD
|
|
LINKTEST
|
|
OPENFILE
|
|
INODE
|
|
STREAM
|
|
FTEST
|
|
LFTEST
|
|
WRITETEST.
|
|
|
|
IOGEN & DOIO
|
|
=============
|
|
|
|
This is a pair of programs that does basic I/O operations on a set of files.
|
|
The file offset, I/O length, I/O operation, and what open(2) flags are
|
|
selected randomly from a pre-defined or commandline given set. All data
|
|
written can be verified (this is the usual method).
|
|
|
|
RWTest
|
|
-----
|
|
rwtest is a shell script that is a wrapper of iogen and doio.
|
|
|
|
Growfiles
|
|
--------
|
|
Growfiles will create and truncate files in gradual steps using write and lseek.
|
|
The system calls are checked for proper returns.
|
|
|
|
FS_INOD
|
|
============
|
|
|
|
File system stress - inode allocation/deallocation.
|
|
Rapidly creates and deletes files through multiple processes running in the
|
|
background.
|
|
|
|
|
|
LINKTEST
|
|
===========
|
|
|
|
Linktest.pl is a simple test that attempts to create a given number of hard
|
|
links and symbolic links to a single file.
|
|
|
|
|
|
OPENFILE
|
|
===========
|
|
|
|
Create files and open simultaneously.
|
|
|
|
INODE
|
|
==================
|
|
|
|
Does the File system managment and I/O functions work.
|
|
This Construct a directory tree, create files in it, and verify
|
|
that this was done as expected. It uses the syscalls mkdir, stat, open
|
|
|
|
|
|
STREAM
|
|
============
|
|
|
|
Performs different tests on the stream syscalls.
|
|
This uses the syscalls freopen, fopen, mknod, ftell, fwrite, fread, ferror,
|
|
feof, clearerr and fileno.
|
|
|
|
FTEST
|
|
=========
|
|
Tests the file I/O, Inodes.
|
|
Uses the syscalls
|
|
* lseek, read, write, truncate, ftruncate, fsync, sync, fstat
|
|
* open, close, unlink, chdir, readv, writev, lseek64, llseek
|
|
|
|
LFTEST
|
|
==========
|
|
|
|
Uses the lseek64.
|
|
This writes one buffer at a time and lseeks from the beginning of the file to the
|
|
end of the last write position
|
|
|
|
|
|
WRITETEST
|
|
=============
|
|
|
|
This test verifies that writes to disk occur without corruption.
|
|
Once done , the file is re-opened, the random number generator
|
|
is re-seeded, and the file is verified.
|
|
|
|
IOCTL
|
|
========
|
|
( Note: Writing the tests to include tests on the ioctl system calls.)
