2021-04-02EVP: Add EVP_<TYPE>_description()Richard Levitte
The following operation types are covered: EVP_MD, EVP_CIPHER, EVP_MAC, EVP_RAND, EVP_KEYMGMT, EVP_SIGNATURE, EVP_ASYM_CIPHER, EVP_KEM, EVP_KEYEXCH, EVP_KDF. Also EVP_PKEY. For EVP_MD and EVP_CIPHER, OBJ_nid2ln() is used as a fallback for legacy implementations. For EVP_PKEY, the info field of the EVP_PKEY_ASN1_METHOD is used as a fallback for legacy implementations.

2021-04-02CORE: Add an algorithm_description field to OSSL_ALGORITHMRichard Levitte
This corresponds to the |info| field in EVP_PKEY_ASN1_METHOD, as well as the generic use of OBJ_nid2ln() as a one line description. We also add the base functionality to make use of this field.

2021-02-25Don't hold a lock when calling a callback in ossl_namemap_doall_namesMatt Caswell
We don't want to hold a read lock when calling a user supplied callback. That callback could do anything so the risk of a deadlock is high. Instead we collect all the names first inside the read lock, and then subsequently call the user callback outside the read lock.

2021-01-14Enable locking on the primary DRBG when we create itMatt Caswell
The primary DRBG may be shared across multiple threads and therefore we must use locking to access it. Previously we were enabling that locking lazily when we attempted to obtain one of the child DRBGs. Part of the process of enabling the lock, is to create the lock. But if we create the lock lazily then it is too late - we may race with other threads where each thread is independently attempting to enable the locking. This results in multiple locks being created - only one of which "sticks" and the rest are leaked. Instead we enable locking on the primary when we first create it. This is already locked and therefore we cannot race. Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/13660)

2020-10-15Rename OPENSSL_CTX prefix to OSSL_LIB_CTXDr. Matthias St. Pierre
Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix, e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER. The OPENSSL_CTX type stands out a little by using a different prefix. For consistency reasons, this type is renamed to OSSL_LIB_CTX.

2020-08-07rand_drbg: remove RAND_DRBG.Pauli
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. 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).

2020-06-24Make the naming scheme for dispatched functions more consistentDr. Matthias St. Pierre
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 | Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/12222)
2020-06-24CTR, HASH and HMAC DRBGs in providerPauli
Move the three different DRBGs to the provider. As part of the move, the DRBG specific data was pulled out of a common structure and into their own structures. Only these smaller structures are securely allocated. This saves quite a bit of secure memory: +-------------------------------+ | DRBG | Bytes | Secure | +--------------+-------+--------+ | HASH | 376 | 512 | | HMAC | 168 | 256 | | CTR | 176 | 256 | | Common (new) | 320 | 0 | | Common (old) | 592 | 1024 | +--------------+-------+--------+ Bytes is the structure size on the X86/64. Secure is the number of bytes of secure memory used (power of two allocator).
