For a kernel to be FIPS-compliant, signature checking would have to be tested before being used, and the box would need to panic if it's not available (probably reasonable as simply disabling signature checking would prevent you from loading any driver modules). Deal with this by adding a minimal test. This is split into two patches: the first moves load_certificate_list() to the same place as the X.509 code to make it more accessible internally; the second adds a selftest" * tag 'certs-20220621' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: certs: Add FIPS selftests certs: Move load_certificate_list() to be with the asymmetric keys code
