In linux kernel since version 6.1.145 (release Date: 2025-07-14)
Enable the cryptographic self-tests.
The cryptographic self-tests run at boot time, or at algorithm
registration time if algorithms are dynamically loaded later.
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.
