| Subject: [PATCH] fix typo/thinko in get_random_bytes() |
| |
| commit bd29e568a4cb6465f6e5ec7c1c1f3ae7d99cbec1 upstream. |
| |
| If there is an architecture-specific random number generator we use it |
| to acquire randomness one "long" at a time. We should put these random |
| words into consecutive words in the result buffer - not just overwrite |
| the first word again and again. |
