| 26 | * Basic tests for setxattr(2) and make sure setxattr(2) handles error |
| 27 | * conditions correctly. |
| 28 | * |
| 29 | * There are 7 test cases: |
| 30 | * 1. Any other flags being set except XATTR_CREATE and XATTR_REPLACE, |
| 31 | * setxattr(2) should return -1 and set errno to EINVAL |
| 32 | * 2. With XATTR_REPLACE flag set but the attribute does not exist, |
| 33 | * setxattr(2) should return -1 and set errno to ENOATTR |
| 34 | * 3. Create new attr with name length greater than XATTR_NAME_MAX(255) |
| 35 | * setxattr(2) should return -1 and set errno to ERANGE |
| 36 | * 4. Create new attr whose value length is greater than XATTR_SIZE_MAX(65536) |
| 37 | * setxattr(2) should return -1 and set errno to E2BIG |
| 38 | * 5. Create new attr whose value length is zero, |
| 39 | * setxattr(2) should succeed |
| 40 | * 6. Replace the attr value without XATTR_REPLACE flag being set, |
| 41 | * setxattr(2) should return -1 and set errno to EEXIST |
| 42 | * 7. Replace attr value with XATTR_REPLACE flag being set, |
| 43 | * setxattr(2) should succeed |
