Subject: [PATCH] KEYS: asymmetric: Add missing dependencies of FIPS_SIGNATURE_SELFTEST
Date: Mon, 22 Apr 2024 14:10:41 -0700
Message-ID: <20240422211041.322370-1-ebiggers@kernel.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Eric Biggers <ebiggers@google.com>

Since the signature self-test uses RSA and SHA-256, it must only be
enabled when those algorithms are enabled.  Otherwise it fails and
panics the kernel on boot-up.

Closes: https://lore.kernel.org/oe-lkp/202404221528.51d75177-lkp@intel.com
