The X942 KDF had been modified so that it supports all optional fields - not
just the fields used by CMS.
As there are 2 types of KDF for X942 - this has been made a bit clearer
by adding an X942KDF-ASN1 alias. X942KDF-CONCAT has also been added as an
alias of X963KDF.
This work was instigated as a result of the ACVP tests optionally being

Instead of sometimes, and sometimes not reporting an error in the
caller of EVP_XXX_fetch(), where the error may or may not be very
accurate, it's now centralised to the inner EVP fetch functionality.
It's made in such a way that it can determine if an error occured
because the algorithm in question is not there, or if something else
went wrong, and will report EVP_R_UNSUPPORTED_ALGORITHM for the
former, and EVP_R_FETCH_FAILED for the latter.

If we failed to fetch an EVP_KEYMGMT then we were falling back to legacy.
This is because some algorithms (such as MACs and KDFs used via an old
style EVP_PKEY) have not been transferred to providers.
Unfortunately this means that you cannot stop some algorithms from being
used by not loading the provider.
For example if you wanted to prevent RSA from being used, you might expect
to just not load any providers that make it available. Unfortunately that
doesn't work because we simply fall back to legacy if we fail to fetch
the EVP_KEYMGMT.
Instead we should fail *unless* the key type is one of those legacy key
types that we have not transferred.

those tests that call test_get_argument() without first skipping over these
common test options will not get the expected value. Some tests did this
correctly but a large number did not.
A helper function is introduced, test_skip_common_options(), to make this

The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.
The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.
A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

tell what providers a certain algorithm may be available in. Only one
provider needs to match, so one might have something like this for
some tests:
Availablein = default fips
This means that one of those providers must be available for the test
stanza to be performed.
If the providers mentioned for a stanza aren't available, the test is
