Subject: [PATCH master] lib: select HAS_INSECURE_DEFAULTS from ALLOW_PRNG_FALLBACK
Date: Thu, 17 Apr 2025 08:23:49 +0200 [thread overview]
Message-ID: <20250417062349.3430967-1-a.fatoum@pengutronix.de> (raw)
PRNG fallback inside get_crypto_bytes is only useful for debugging
and a really bad idea in production. We already warn about this at
runtime, but let's make sure it's directly evident in the config as
well.
