We've spread around FETCH_FAILED errors in quite a few places, and
that gives somewhat crude error records, as there's no way to tell if
the error was unavailable algorithms or some other error at such high
levels.
As an alternative, we take recording of these kinds of errors down to
the fetching functions, which are in a much better place to tell what
kind of error it was, thereby relieving the higher level calls from
having to guess.

The EVP lib was calling EVP_CIPHER_CTX_block_size(), which in turn calls
EVP_CIPHER_block_size() in order to find the block_size in every
EVP_EncryptUpdate() call. This adds a surprising amount of overhead when
using speed to test aes-128-cbc. Since we're in the EVP lib itself, we can
just directly access this value.
To test performance I ran the command:
openssl speed -evp aes-128-cbc -bytes 16 -seconds 30
For the before and after, I ran this twice and discarded the first result
to "warm up" my machine.
Before:
aes-128-cbc 716949.71k
After:
aes-128-cbc 742807.11k
This represents a performance improvement of about 4%

EVP_CIPHER already caches certain constants so that we don't have to

Without this we can get performance issues, e.g. running "speed" with

this means we do the caching every time we call that function, even if
the core has previusly fetched the cipher and cached it already. This
means we can end up re-caching the constants even though they are already

This commit tries to address a locking issue in evp_pkey_reset_unlocked
which can occur when it is called from evp_pkey_downgrade.
evp_pkey_downgrade will acquire a lock for pk->lock and if successful
then call evp_pkey_reset_unlocked. evp_pkey_reset_unlocked will call
memset on pk, and then create a new lock and set pk->lock to point to
that new lock. I believe there are two problems with this.
The first is that after the call to memset, another thread would try to
acquire a lock for NULL as that is what the value of pk->lock would be
at that point.
The second issue is that after the new lock has been assigned to
pk->lock, that lock is different from the one currently locked so
another thread trying to acquire the lock will succeed which can lead to
strange behaviour. More details and a reproducer can be found in the
Refs link below.
This changes the evp_pkey_reset_unlocked to not touch the lock
and the creation of a new lock is done in EVP_PKEY_new.

It is superseded by EVP_CIPHER_CTX_get_iv(), is only present on master,

(Merged from https://github.com/openssl/openssl/pull/12233)
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.

The default and legacy providers currently return 1 for status and self test checks.
Added test to show the 3 different stages the self test can be run (for installation, loading and on demand).
For the fips provider:
- If the on demand self test fails, then any subsequent fetches should also fail. To implement this the
cached algorithms are flushed on failure.
- getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core
libctx (as it is set by the application) not the actual fips library context. Also the callback can be set at
any time not just during the OSSL_provider_init() so it is calculated each time before doing any self test.

The RAND_DRBG API did not fit well into the new provider concept as
implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the
RAND_DRBG API is a mixture of 'front end' and 'back end' API calls
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.

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

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.

- evp_pkey_is_provided(), to detect that the internal EVP_PKEY key is

This allows the digests that are indicated by RSA PSS parameters
to have a useful propquery.

There were a few instances where we set the EVP_PKEY_CTX operation to
EVP_PKEY_OP_UNDEFINED, but forgot to clean up first. After the
operation is made undefined, there's no way to know what should be
cleaned away, so that must be done first, in all spots.

EVP_PKEY_CTX_gettable_params() was missing code for the keygen operation.
After adding it it was noticed that it is probably not required for this type, so instead
the gen_get_params and gen_gettable_params have been remnoved from the provider interface.
gen_get_params was only implemented for ec to get the curve name. This seems redundant
since normally you would set parameters into the keygen_init() and then generate a key.
Normally you would expect to extract data from the key - not the object that we just set up
to do the keygen.
Added a simple settable and gettable test into a test that does keygen.
