| * TEST IDENTIFIER : munlockall02 |
| * |
| * EXECUTED BY : root / superuser |
| * |
| * TEST TITLE : test for EPERM error value when run as non superuser |
| * |
| * TEST CASE TOTAL : 1 |
| * |
| * AUTHOR : sowmya adiga<sowmya.adiga@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * Verify munlockall(2) returns -1 and sets errno to EPERM |
| * if the effective userid of the caller is not super-user. |
| * $ |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * Change effective user id to "nobody" user |
| * $ |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * Check return code, if system call failed (return=-1) && |
| * (errno set == expected errno) |
| * Issue sys call pass with expected return value and errno. |
| * otherwise, |
| * Issue sys call fails with unexpected errno. |
| * |
| * |
| * Cleanup: |
| * change effective user id to root |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * munlockall02 [-c n] [-e] [-i n] [-I x] [-p x] [-t] |
| * where, -c n : Run n copies concurrently |
| * -e : Turn on errno logging. |
| * -h : Show this help screen |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -p : Pause for SIGUSR1 before starting |
| * -P x : Pause for x seconds between iterations. |
| * t : Turn on syscall timing. |
| * |
