Just for the records: for FIPS 140-2 rules, cipher_null is to be interpreted
as a memcpy on SGLs. Thus it is no cipher even though it sounds like one.
cipher_null is also needed for seqiv which

The cipher_null is not a real cipher, FIPS mode should not restrict its use.
It is used for several tests (for example in cryptsetup testsuite) and also
temporarily for reencryption of not yet encrypted device in
cryptsetup-reencrypt tool.
Problem is easily reproducible with
