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.

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.

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.

2020-10-01EVP: use evp_pkey_ctx_is_legacy() to find what implementation to useRichard Levitte
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 macro that gets used everywhere.

2020-09-08EVP: Add support for delayed EVP_PKEY operation parametersRichard Levitte
They get called "delayed parameters" because they may make it to the implementation at a later time than when they're given. This currently only covers the distinguished ID, as that's the only EVP_PKEY operation parameter so far that has been possible to give before the operation has been initialized. This includes a re-implementation of EVP_PKEY_CTX_set1_id(), EVP_PKEY_CTX_get1_id(), and EVP_PKEY_CTX_get1_id_len(). Also, the more rigorous controls of keytype and optype are restored.

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)
2020-05-14EVP: For SIGNATURE operations, pass the propquery earlyRichard Levitte
Instead of passing it with signature->digest_verify_init() and signature->digest_sign_init(), we pass it with signature->newctx().

2020-05-08EVP: when setting the operation to EVP_PKEY_OP_UNDEFINED, clean up!Richard Levitte
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.

2020-03-21EVP: fetch the EVP_KEYMGMT earlierRichard Levitte
Instead of fetching the EVP_KEYMGMT in the init for every different operation, do it when creating the EVP_PKEY_CTX. This allows certain control functions to be called between the creation of the EVP_PKEY_CTX and the call of the operation's init function. Use case: EVP_PKEY_CTX_set1_id(), which is allowed to be called very early with the legacy implementation, this should still be allowed with provider implementations.

2020-03-09EVP: Check that key methods aren't foreign when exportingRichard Levitte
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 with provider side keys in any function, that function will fail.

2020-02-29Rethink the EVP_PKEY cache of provider side keysRichard Levitte
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.

2020-02-07Redesign the KEYMGMT libcrypto <-> provider interface - the basicsRichard Levitte
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) Fixes #10979 squash!

Since we're falling back to legacy, this isn't an error any more. Among others the failed EVP_KEYMGMT_fetch() error shadows other errors produced by the legacy code, which disrupts our test/evp_test runs.

2020-01-18EVP: Add evp_pkey_make_provided() and refactor around itRichard Levitte
The code to ensure that an EVP_PKEY is exported to providers is repeated all over the place, enough that copying it again has the usual future hazards with code copying. Instead, we refactor that code into one function, evp_pkey_make_provided(), and make sure to use that everywhere. It relies on the creation of EVP_PKEY_CTX to figure out facts about the input key, should it need to.

These functions would only handle provided methods, but there are cases where the caller just passes along a received method without knowing the underlying method tech, so might pass along a legacy method. We therefore need to have them handle this case as well so they don't cause any unnecessary surprises.
