We've had explicit checks for when to fall back to legacy code for
operations that use an EVP_PKEY. Unfortunately, the checks were
radically different in different spots, so we refactor that into a

As discussed in the issue, supporting the set0-like semantics long-term is not necessarily desirable, although necessary for short-term compatibility concerns. So I've deprecated the original method and added an equivalent that is explicitly labelled as set1.
I tried to audit existing usages of the (now-deprecated) API and update them to use set1 if that appeared to align with their expectations.

The EVP_CIPHER_CTX_iv() family of functions are incompatible with
the libcrypto/provider separation, since the implied API contract
(they are undocumented) involves a pointer into the active cipher
context structure. However, the active IV data in a provider-side
context need not even be in the same address space as libcrypto,
so a replacement API is needed.
The existing functions for accessing the (even the "original") IV had
remained undocumented for quite some time, presumably due to unease
about exposing the internals of the cipher state in such a manner.
Provide more maintainable new APIs for accessing the initial ("oiv") and
current-state ("iv") IV data, that copy the value into a caller-provided
array, eliminating the need to provide a pointer into the internal
cipher context, which accordingly no longer provides the ability to
write to the internal cipher state.
Unfortunately, in order to maintain API compatibility with OpenSSL
1.1.1, the old functionality is still available, but is marked as
deprecated for future removal. This would entail removing the "octet
pointer" parameter access, leaving only the "octet string" parameter
type.

Some modes (e.g., CBC and OFB) update the effective IV with each
block-cipher invocation, making the "IV" stored in the (historically)
EVP_CIPHER_CTX or (current) PROV_CIPHER_CTX distinct from the initial
IV passed in at cipher initialization time. The latter is stored in
the "oiv" (original IV) field, and has historically been accessible
via the EVP_CIPHER_CTX_original_iv() API. The "effective IV" has
also historically been accessible, via both EVP_CIPHER_CTX_iv()
and EVP_CIPHER_CTX_iv_noconst(), the latter of which allows for
*write* access to the internal cipher state. This is particularly
problematic given that provider-internal cipher state need not, in
general, even be accessible from the same address space as libcrypto,
so these APIs are not sustainable in the long term. However, it still
remains necessary to provide access to the contents of the "IV state"
(e.g., when serializing cipher state for in-kernel TLS); a subsequent
reinitialization of a cipher context using the "IV state" as the
input IV will be able to resume processing of data in a compatible
manner.
This problem was introduced in commit
089cb623be, which effectively caused
all IV queries to return the "original IV", removing access to the
current IV state of the cipher.
These functions for accessing the (even the "original") IV had remained
undocumented for quite some time, presumably due to unease about
exposing the internals of the cipher state in such a manner.
Note that this also as a side effect "fixes" some "bugs" where things
had been referring to the 'iv' field that should have been using the
'oiv' field. It also fixes the EVP_CTRL_GET_IV cipher control,
which was clearly intended to expose the non-original IV, for
use exporting the cipher state into the kernel for kTLS.

- getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core

and some of its API calls are rather low-level. This holds in particular
for the callback mechanism (RAND_DRBG_set_callbacks()) and the RAND_DRBG
type changing mechanism (RAND_DRBG_set()).
Adding a compatibility layer to continue supporting the RAND_DRBG API as
a legacy API for a regular deprecation period turned out to come at the
price of complicating the new provider API unnecessarily. Since the
RAND_DRBG API exists only since version 1.1.1, it was decided by the OMC
to drop it entirely.
Other related changes:
Use RNG instead of DRBG in EVP_RAND documentation. The documentation was
using DRBG in places where it should have been RNG or CSRNG.
Move the RAND_DRBG(7) documentation to EVP_RAND(7).

The only reason we should fallback to legacy codepaths in DigestSignInit/
DigestVerifyInit, is if we have an engine, or we have a legacy algorithm
that does not (yet) have a provider based equivalent (e.g. SM2, HMAC, etc).
Currently we were falling back even if we have a suitable key manager but
the export of the key fails. This might be for legitimate reasons (e.g.
we only have the FIPS provider, but we're trying to export a brainpool key).
In those circumstances we don't want to fallback to the legacy code.
Therefore we tighten then checks for falling back to legacy. Eventually this
particular fallback can be removed entirely (once all legacy algorithms have
provider based key managers).

Calling Init()/Update() and then Init()/Update() again gave a different result when using the same key and iv.
Cipher modes that were using ctx->num were not resetting this value, this includes OFB, CFB & CTR.
The fix is to reset this value during the ciphers einit() and dinit() methods.
Most ciphers go thru a generic method so one line fixes most cases.
Add test for calling EVP_EncryptInit()/EVP_EncryptUpdate() multiple times for all ciphers.
Ciphers should return the same value for both updates.

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

EVP_PKEYs with provider side internal keys got the key type
EVP_PKEY_NONE. This turned out to be too disruptive, so we try
instead to find a matching EVP_PKEY_ASN1_METHOD and use whatever
EVP_PKEY type it uses.
To make internal coding easier, we introduce a few internal macros to
distinguish what can be expected from a EVP_PKEY:
- evp_pkey_is_blank(), to detect an unassigned EVP_PKEY.
- evp_pkey_is_typed(), to detect that an EVP_PKEY has been assigned a
type, which may be an old style type number or a EVP_KEYMGMT method.
- evp_pkey_is_assigned(), to detect that an EVP_PKEY has been assigned
an key value.
- evp_pkey_is_legacy(), to detect that the internal EVP_PKEY key is a
legacy one, i.e. will be handled via an EVP_PKEY_ASN1_METHOD and an
EVP_PKEY_METHOD.
- evp_pkey_is_provided(), to detect that the internal EVP_PKEY key is
a provider side one, i.e. will be handdled via an EVP_KEYMGMT and
other provider methods.
This also introduces EVP_PKEY_KEYMGMT, to indicate that this EVP_PKEY
contains a provider side key for which there are no known
EVP_PKEY_ASN1_METHODs or EVP_PKEY_METHODs, i.e. these can only be
handled via EVP_KEYMGMT and other provider methods.

and fully assigned keys (pk->type != EVP_PKEY_NONE && pk->pkey.ptr != NULL).
For provider side keys, the corresponding states weren't well defined,
and the code didn't quite account for all the possibilities.
We also guard most of the legacy fields in EVP_PKEY with FIPS_MODE, so
they don't exist at all in the FIPS module.
Most of all, code needs to adapt to the case where an EVP_PKEY's
|keymgmt| is non-NULL, but its |keydata| is NULL.

A huge problem with calling digest_custom() already in the
initialization of DigestSign, DigestVerify etc, is that it force all
callers to know that certain controls must be performed before Init
and the rest after. This has lead to quite interesting hacks in our
own openssl app, where the SM2 ID had to get special treatment instead
of just being another sign option or verification option among others.
This change moves the call of digest_custom() to the Update and Final
functions, to be done exactly once, subject to a flag that's set in
the Init function. Seeing to the process of data, through these
operations, this makes no difference at all. Seeing to making it
possible to perform all controls after the Init call, this makes a
huge difference.

The EVP_PKEY_ASN1_METHOD function export_to() must check that the key
we're trying to export has a known libcrypto method, i.e. is a built
in RSA_METHOD, DSA_METHOD, etc. Otherwise, the method may be defined
by the calling application, by an engine, by another library, and we
simply cannot know all the quirks hidden behind that method, if we
have access to the key data, or much anything.
Such keys are simply deemed impossible to export to provider keys,
i.e. have export_to() return 0. This cascades back to functions like
evp_pkey_export_to_provider() and evp_pkey_upgrade_to_provider() and
their callers. In most cases, this is fine, but if these get mixed in

Provide EC serializers for text, pem and der.
EC parameters use ANS1 'CHOICE' - which means they are more embedded than other parameters used by
other KEY types (which normally have a SEQUENCE at the top level).
For this reason the ANS1_STRING type that was being passed around has been changed to a void so that the

The EC serializer only supports named curves currently.
NOTE the serializer code assumes PKCS8 format - if the older encode methods are needed they will need to be
added in another PR. (Probably when deserialization is considered).
EVP_PKEY_key_fromdata_init was changed from using a keypair selection to all bits of a key. A side effect of this was

The role of this cache was two-fold:
1. It was a cache of key copies exported to providers with which an
operation was initiated.
2. If the EVP_PKEY didn't have a legacy key, item 0 of the cache was
the corresponding provider side origin, while the rest was the
actual cache.
This dual role for item 0 made the code a bit confusing, so we now
make a separate keymgmt / keydata pair outside of that cache, which is
the provider side "origin" key.
A hard rule is that an EVP_PKEY cannot hold a legacy "origin" and a
provider side "origin" at the same time.

legacy key or from another provider side key. This works most of the

in control of what sort of export happens when.
Also, when it's time to remove all legacy stuff, that job will be much
easier if we have a better separation between legacy support and
support of provided stuff, as far as we can take it.
This changes moves the support of legacy key to provider side key
export from evp-keymgmt_util_export_to_provider() to
evp_pkey_make_provided(), and makes sure the latter is called from all
EVP_PKEY functions that handle legacy stuff.

The KEYMGMT libcrypto <-> provider interface currently makes a few
assumptions:
1. provider side domain parameters and key data isn't mutable. In
other words, as soon as a key has been created in any (loaded,
imported data, ...), it's set in stone.
2. provider side domain parameters can be strictly separated from the
key data.
This does work for the most part, but there are places where that's a
bit too rigid for the functionality that the EVP_PKEY API delivers.
Key data needs to be mutable to allow the flexibility that functions
like EVP_PKEY_copy_parameters promise, as well as to provide the
combinations of data that an EVP_PKEY is generally assumed to be able
to hold:
- domain parameters only
- public key only
- public key + private key
- domain parameters + public key
- domain parameters + public key + private key
To remedy all this, we:
1. let go of the distinction between domain parameters and key
material proper in the libcrypto <-> provider interface.
As a consequence, functions that still need it gain a selection
argument, which is a set of bits that indicate what parts of the
key object are to be considered in a specific call. This allows
a reduction of very similar functions into one.
2. Rework the libcrypto <-> provider interface so provider side key
objects are created and destructed with a separate function, and
get their data filled and extracted in through import and export.
(future work will see other key object constructors and other
functions to fill them with data)
