7c8187d43d rand: add set0 calls for the private and public DRBGs
The FIPS 140-3 DSA and ECDSA tests need to be known answer tests which means
the entropy needs to be cooked.  This permits this.

c048779520 Add translation for ECX group parameter
Legacy EVP_PKEY_CTX objects did not support the "group" parameter for X25519
and X448.  The translation of this parameter resulted in an error.  This
caused errors for legacy keys and engines.

Fix this situation by adding a translation that simply checks that the correct
parameter is to be set, but does not actually set anything.  This is correct
since the group name is anyway optional for these two curves.

Fixes #19313

e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

25d47cccf2 Fix usage of custom EVP_CIPHER objects
If a custom EVP_CIPHER object has been passed to EVP_CipherInit() then it
should be used in preference to a fetched cipher.

We also fix a possible NULL pointer deref in the same code for digests.

If the custom cipher passed to EVP_CipherInit() happens to use NID_undef
(which should be a discouraged practice), then in the previous
implementation this could result in the NULL cipher being fetched and
hence NULL encryption being unexpectedly used.

78c44b0594 Add HPKE DHKEM provider support for EC, X25519 and X448.
The code is derived from @sftcd's work in PR #17172.
This PR puts the DHKEM algorithms into the provider layer as
KEM algorithms for EC and ECX.

This PR only implements the DHKEM component of HPKE as specified in
RFC 9180.

crypto/hpke/hpke_util.c has been added for fuctions that will
be shared between DHKEM and HPKE.

API's for EVP_PKEY_auth_encapsulate_init() and EVP_PKEY_auth_decapsulate_init()
have been added to support authenticated encapsulation. auth_init() functions
were chosen rather that a EVP_PKEY_KEM_set_auth() interface to support
future algorithms that could possibly need different init functions.

Internal code has been refactored, so that it can be shared between the DHKEM
and other systems. Since DHKEM operates on low level keys it needs to be
able to do low level ECDH and ECXDH calls without converting the keys
back into EVP_PKEY/EVP_PKEY_CTX form. See ossl_ecx_compute_key(),
ossl_ec_public_from_private()

DHKEM requires API's to derive a key using a seed (IKM). This did not sit
well inside the DHKEM itself as dispatch functions. This functionality
fits better inside the EC and ECX keymanagers keygen, since
they are just variations of keygen where the private key is generated
in a different manner. This should mainly be used for testing purposes.
See ossl_ec_generate_key_dhkem().
It supports this by allowing a settable param to be passed to keygen
(See OSSL_PKEY_PARAM_DHKEM_IKM).
The keygen calls code within ec and ecx dhkem implementation to handle this.
See ossl_ecx_dhkem_derive_private() and ossl_ec_dhkem_derive_private().
These 2 functions are also used by the EC/ECX DHKEM implementations to generate
the sender ephemeral keys.

e1eafe8c87 "Reserve" the method store when constructing methods
Introducing the concept of reserving the store where a number of
provided operation methods are to be stored.

This avoids racing when constructing provided methods, which is
especially pertinent when multiple threads are trying to fetch the
same method, or even any implementation for the same given operation
type.

This introduces a |biglock| in OSSL_METHOD_STORE, which is separate
from the |lock| which is used for more internal and finer grained
locking.

4e9a4997c5 Fix memory leak in EVP_PKEY_get1_encoded_public_key.
Occurs if a failure happens after the malloc call in the second call to
EVP_PKEY_get_octet_string_param().

Detected by PR #18355

Some calling code assumes that nothing is allocated in the returned
pointer if there was a failure. Other calling code always trys freeing.
The third case is in ecdh_cms_encrypt() where it does not check the
return value. I am assuming this change is ok since the legacy path in
EVP_PKEY_get1_encoded_public_key() also does not return the pointer on
failure.

221d65ba53 evp_md: assert digest is provided for algctx reuse
When reusing an algctx (it was always freed on reinitialization,
prior to #18105), assert that the associated digest is provided.
We implicitly rely on this for algctx reuse to be safe (since
an implicit fetch could potentially change the digest object used,
including provider, which accordingly could change the layout of the
algctx object.

From code inspection, this is currently always the case -- the only
way to set an algctx requires the provider to be set, and the only
ways to change or remove a provider without destroying the entier
EVP_MD_CTX will also free the algctx.  Adding an assertion will help
ensure that this remains true as the code evolves.

2e4d0677ea Make it possible to remove methods by the provider that provides them
This adds ossl_method_store_remove_all_provided(), which selectively
removes methods from the given store that are provided by the given
provider.

This also adds the EVP specific evp_method_store_remove_all_provided(),
which matches ossl_method_store_remove_all_provided() but can also
retrieve the correct store to manipulate for EVP functions.

This allows us to modify ossl_provider_self_test() to do the job it's
supposed to do, but through clearly defined functions instead of a
cache flushing call that previously did more than that.

ossl_provider_deactivate() is also modified to remove methods associated
with the deactivated provider, and not just clearing the cache.

4908787f21 SM4 optimization for ARM by ASIMD
This patch optimizes SM4 for ARM processor using ASIMD instruction

It will improve performance if both of following conditions are met:
1) Input data equal to or more than 4 blocks
2) Cipher mode allows parallelism, including ECB,CTR,GCM or CBC decryption

This patch implements SM4 SBOX lookup in vector registers, with the
benefit of constant processing time over existing C implementation.

It is only enabled for micro-architecture N1/V1. In the ideal scenario,
performance can reach up to 2.7X

When either of above two conditions is not met, e.g. single block input
or CFB/OFB mode, CBC encryption, performance could drop about 50%.

927d0566de Refactor OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA
This refactors OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA. The assorted
objects to be managed by OSSL_LIB_CTX are hardcoded and are initialized
eagerly rather than lazily, which avoids the need for locking on access
in most cases.

Fixes #17116.

330ff7e67d Use safe math to computer sizes.
The sizes are rounded via the expression: (cmpl + 7) / 8 which overflows if
cmpl is near to the type's maximum.  Instead we use the safe_math function to
computer this without any possibility of error.
