| * TEST IDENTIFIER : setresgid02 |
| * |
| * EXECUTED BY : root / superuser |
| * |
| * TEST TITLE : Checking functionality of setresgid(2) for |
| * non-root group id. |
| * |
| * TEST CASE TOTAL : 6 |
| * |
| * AUTHOR : Madhu T L <madhu.tarikere@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * Verify that for non-root effective group id, |
| * 1. setresgid(2) is successful for setresgid(-1, -1, -1) |
| * 2. setresgid(2) is successful for setresgid(-1, -1, bin) |
| * 3. setresgid(2) is successful for setresgid(-1, bin, -1) |
| * 4. setresgid(2) is successful for setresgid(bin, -1, -1) |
| * 5. setresgid(2) is successful for setresgid(root, root, root) |
| * 6. setresgid(2) is successful for setresgid(root, nobody, nobody) |
| * |
| * Setup: |
| * Setup signal handling. |
| * Test caller is superuser |
| * Check existence of root, bin and nobody user id's |
| * Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * Check return value and functionality, if success, |
| * Issue PASS message |
| * Otherwise, |
| * Issue FAIL message |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * setresgid02 [-c n] [-e] [-f] [-h] [-i n] [-I x] [-p] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -f : Turn off functional testing |
| * -h : Show 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. |
| * |
| * CHANGE: Madhu T L <madhu.tarikere@wipro.com> |
| * Date: April 9 2003 |
| * Replaced setegid() by setresgid() in setup() |
