| * TEST IDENTIFIER : setdomainname02 |
| * |
| * EXECUTED BY : root / superuser |
| * |
| * TEST TITLE : test for checking error conditions for setdomainame(2) |
| * |
| * TEST CASE TOTAL : 3 |
| * |
| * AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * Verify that, |
| * 1) setdomainname(2) returns -1 and sets errno to EINVAL if the parameter, |
| * len is less than zero |
| * 2) setdomainname(2) returns -1 and sets errno to EINVAL if value of |
| * len is greater than the maximum allowed value |
| * 3) setdomainname(2) returns -1 and sets errno to EFAULT for a bad address |
| * for name |
| * |
| * ALGORITHM |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * Save current domainname |
| * |
| * 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 fails with expected return value and errno. |
| * Otherwise, |
| * Issue sys call returns unexpected value. |
| * |
| * Cleanup: |
| * Restore old domain name. |
| * Print errno log and/or timing stats if options given |
| * Side Effects : |
| * setdomainname() is resetting value to NULL, if an invalid address |
| * is given for name. So, to overcome this problem, domainname is |
| * resetting to original value as part of cleanup() routine. |
| * |
| * USAGE: <for command-line> |
| * setdomainname02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -h : Show help screen |
| * -f : Turn off functional testing |
| * -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. |
