| * TEST IDENTIFIER : syslog12 |
| * |
| * EXECUTED BY : root / superuser |
| * |
| * TEST TITLE : Checking error conditions for syslog(2) |
| * |
| * TEST CASE TOTAL : 7 |
| * |
| * 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, |
| * 1. syslog(2) fails with EINVAL for invalid type/command |
| * 2. syslog(2) fails with EFAULT for buffer outside program's accessible |
| * address space. |
| * 3. syslog(2) fails with EINVAL for NULL buffer argument. |
| * 4. syslog(2) fails with EINVAL for length arg. set to negative value. |
| * 5. syslog(2) fails with EPERM for non-root user. |
| * 6. syslog(2) fails with EINVAL for console level less than 0. |
| * 7. syslog(2) fails with EINVAL for console level greater than 8. |
| * |
| * Setup: |
| * Setup signal handling. |
| * Test caller is superuser |
| * Check existence of user nobody |
| * Set expected errnos |
| * Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * Check return value and errno, if matching, |
| * Issue PASS message |
| * Otherwise, |
| * Issue FAIL message |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * syslog12 [-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. |
