This avoids code duplication and provides variable-size support
for BLAKE2s like 786b9a8
Test data obtained with libb2 with the following programs:
==> b2.c <==
#include <blake2.h>
#include <unistd.h>
int main() {
char buf[16] = {};
blake2s(buf, 0, 0, 16, 0, 0);
write(1, buf, 16);
}
==> b3.c <==
#include <blake2.h>
#include <unistd.h>
int main() {
char buf[10] = {};
blake2s(buf, "\x61", 0, 10, 1, 0);
write(1, buf, 10);
}

BLAKE2 is not really an extensible output function unlike SHAKE
as the digest size must be set during the context initialization.
Thus it makes no sense to use OSSL_DIGEST_PARAM_XOFLEN.
We also need to adjust EVP_DigestFinal_ex() to query the
OSSL_DIGEST_PARAM_SIZE as gettable ctx param for the size.

The function `ossl_blake2b_param_init` should initialise only, and not

For some reason, the code here was made to got through the provider
specific init functions. This is very very dangerous if the provider
specific functions were to change in any way (such as changes to the
implementation context structure).
Instead, use the init functions from the base blake2 implementations
directly.

The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all
functions which are dispatched between the core and providers.
This change includes in particular all up- and downcalls, i.e., the
dispatched functions passed from core to provider and vice versa.
- OSSL_core_ -> OSSL_FUNC_core_
- OSSL_provider_ -> OSSL_FUNC_core_
For operations and their function dispatch tables, the following convention
is used:
Type | Name (evp_generic_fetch(3)) |
---------------------|-----------------------------------|
operation | OSSL_OP_FOO |
function id | OSSL_FUNC_FOO_FUNCTION_NAME |
function "name" | OSSL_FUNC_foo_function_name |
function typedef | OSSL_FUNC_foo_function_name_fn |
function ptr getter | OSSL_FUNC_foo_function_name |

From providers/{common,default,legacy}/ to providers/implementations/
However, providers/common/digests/digest_common.c stays where it is,
because it's support code rather than an implementation.
To better support all kinds of implementations with common code, we
add the library providers/libcommon.a. Code that ends up in this
library must be FIPS agnostic.
While we're moving things around, though, we move digestscommon.h
from providers/common/include/internal to providers/common/include/prov,
thereby starting on a provider specific include structure, which
follows the line of thoughts of the recent header file reorganization.
We modify the affected '#include "internal/something.h"' to
'#include "prov/something.h"'.
