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.)
