| 21 | * |
| 22 | * Test Description: |
| 23 | * Verify that, chmod(2) will succeed to change the mode of a file |
| 24 | * and set the sticky bit on it if invoked by non-root (uid != 0) |
| 25 | * process with the following constraints, |
| 26 | * - the process is the owner of the file. |
| 27 | * - the effective group ID or one of the supplementary group ID's of the |
| 28 | * process is equal to the group ID of the file. |

plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 30 | * Expected Result: |
| 31 | * chmod() should return value 0 on success and succeeds to change |
| 32 | * the mode of specified file with sticky bit set on it. |
| 33 | * |
| 34 | * Algorithm: |
| 35 | * Setup: |
| 36 | * Setup signal handling. |
| 37 | * Create temporary directory. |
| 38 | * Pause for SIGUSR1 if option specified. |
| 39 | * |
| 40 | * Test: |
| 41 | * Loop if the proper options are given. |
| 42 | * Execute system call |
| 43 | * Check return code, if system call failed (return=-1) |
| 44 | * Log the errno and Issue a FAIL message. |
| 45 | * Otherwise, |
subrata_modak | bdbaec5 | 2009-02-26 12:14:51 +0000 | [diff] [blame] | 46 | * Verify the Functionality of system call |
plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 47 | * if successful, |
| 48 | * Issue Functionality-Pass message. |
| 49 | * Otherwise, |
| 50 | * Issue Functionality-Fail message. |
| 51 | * Cleanup: |
| 52 | * Print errno log and/or timing stats if options given |
| 53 | * Delete the temporary directory created. |
| 54 | * |
| 55 | * Usage: <for command-line> |
| 56 | * chmod03 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t] |
| 57 | * where, -c n : Run n copies concurrently. |
| 58 | * -e : Turn on errno logging. |
| 59 | * -f : Turn off functionality Testing. |
| 60 | * -i n : Execute test n times. |
| 61 | * -I x : Execute test for x seconds. |
| 62 | * -P x : Pause for x seconds between iterations. |
| 63 | * -t : Turn on syscall timing. |
| 64 | * |
| 65 | * HISTORY |

| 68 | * RESTRICTIONS: |
