Mon Apr 8 08:52:27 CEST 2019
1) Take use of some safe macros
2) Remove duplicate tests stat06
3) Add ELOOP check
4) Remove useless struct member

- * Test Name: stat03
- *
- * Test Description:
- * Verify that,
- * 1) stat(2) returns -1 and sets errno to EACCES if search permission is
- * denied on a component of the path prefix.
- * 2) stat(2) returns -1 and sets errno to ENOENT if the specified file
- * does not exists or empty string.
- * 3) stat(2) returns -1 and sets errno to EFAULT if pathname points
- * outside user's accessible address space.
- * 4) stat(2) returns -1 and sets errno to ENAMETOOLONG if the pathname
- * component is too long.
- * 5) stat(2) returns -1 and sets errno to ENOTDIR if the directory
- * component in pathname is not a directory.
- *
- * Expected Result:
- * stat() should fail with return value -1 and set expected errno.
- *
- * Algorithm:
- * Setup:
- * Setup signal handling.
- * Create temporary directory.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * if errno set == expected errno
- * Issue sys call fails with expected return value and errno.
- * Otherwise,
- * Issue sys call fails with unexpected errno.
- * Otherwise,
- * Issue sys call returns unexpected value.
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
- * Delete the temporary directory(s)/file(s) created.
- *
- * Usage: <for command-line>
- * stat03 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
- * where, -c n : Run n copies concurrently.
- * -e : Turn on errno logging.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.

- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * Log the errno and Issue a FAIL message.
- * Otherwise, Issue a PASS message.
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
