- API: add failure mode support for randombytes()
- autogen: run to update randombytes declaration
- randombytes: add example to test failure
Change randombytes() to return int (0 on success, non-zero on failure) instead of void, allowing callers to detect and handle RNG failures. Updated function signature, all call sites to check return values and test files to use CHECK macro. Signed-off-by: Andreas Hatziiliou <andreas.hatziiliou@savoirfairelinux.com>
Run the autogen script to reflect the changes made to the randombytes() API. Signed-off-by: Andreas Hatziiliou <andreas.hatziiliou@savoirfairelinux.com>
This commit introduces a new example build which is meant to test the failure mode to the randombytes API. The randombytes_force_failure(n) function ensures that the nth call to randombytes will fail. Signed-off-by: Andreas Hatziiliou <andreas.hatziiliou@savoirfairelinux.com>
