Enable the cryptographic self-tests.
The cryptographic self-tests run at boot time, or at algorithm
registration time if algorithms are dynamically loaded later.
- This is primarily intended for developer use. It should not be
- enabled in production kernels, unless you are trying to use these
- tests to fulfill a FIPS testing requirement.
+ There are two main use cases for these tests:
+
+ - Development and pre-release testing. In this case, also enable
+ CRYPTO_SELFTESTS_FULL to get the full set of tests. All crypto code
+ in the kernel is expected to pass the full set of tests.
+
+ - Production kernels, to help prevent buggy drivers from being used
+ and/or meet FIPS 140-3 pre-operational testing requirements. In
+ this case, enable CRYPTO_SELFTESTS but not CRYPTO_SELFTESTS_FULL.
