| 4 | * Text: "prng runs in TDES mode with chunksize=%d and reseed_limit=%u\n" | |

| 8 | * @2: reseed limit | |
| 9 | * Description: | |
| 10 | * The pseudo-random number device driver started in triple DES mode. | |
| 11 | * For IBM mainframes earlier than IBM zEnterprise EC12 (zEC12), | |
| 12 | * triple DES is the only available mode. | |
| 13 | * As of zEC12, the preferred mode is SHA-512. | |
| 14 | * User action: | |
| 15 | * If triple DES is the expected mode, no action is required. | |
| 16 | * Otherwise, verify that the prng started with the mode= module or | |
| 17 | * prng.mode= kernel parameter set to a value other than 1. | |
| 18 | * The value 1 forces triple DES mode. Also ensure that the mainframe | |
| 19 | * runs with the latest firmware level. | |

| 35 | * Severity: Error | |
| 36 | * Description: | |
| 37 | * The pseudo-random number device driver was loaded with the mode= module parameter | |
| 38 | * or the prng.mode= kernel parameter set to 2. This setting forces SHA-512 mode, | |
| 39 | * but the required support for MSA 5 is not available. This support requires an IBM | |
| 40 | * zEnterprise EC12 (zEC12) or later mainframe. | |
| 41 | * User action: | |
| 42 | * If your mainframe is earlier than zEC12, set the mode= module or | |
| 43 | * prng.mode= kernel parameter to 0 or 1 to run the | |
| 44 | * pseudo-random number device driver in triple DES mode. | |
| 45 | * Otherwise, ensure that MSA 5 support available. | |
