pointers to provider size algorithm contexts. Fixes #14284 The gettable_ctx_params methods were confusingly passing a 'provctx' and a provider context which are completely different objects. Some objects such as EVP_KDF used 'data' while others such as EVP_MD used 'provctx'. For libcrypto this 'ctx' is an opaque ptr returned when a providers algorithm implementation creates an internal context using a new_ctx() method. Hence the new name 'algctx'.

2021-04-18Add "origin" field to EVP_CIPHER, EVP_MDRich Salz
Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch, or via EVP_{CIPHER,MD}_meth_new. Update EVP_{CIPHER,MD}_free to handle all three origins. The flag is deliberately right before some function pointers, so that compile-time failures (int/pointer) will occur, as opposed to taking a bit in the existing "flags" field. The "global variable" flag is non-zero, so the default case of using OPENSSL_zalloc (for provider ciphers), will do the right thing. Ref-counting is a no-op for Make up_ref no-op for global MD and CIPHER objects Deprecate EVP_MD_CTX_md(). Added EVP_MD_CTX_get0_md() (same semantics as the deprecated function) and EVP_MD_CTX_get1_md(). Likewise, deprecate EVP_CIPHER_CTX_cipher() in favor of EVP_CIPHER_CTX_get0_cipher(), and add EVP_CIPHER_CTX_get1_CIPHER(). Refactor EVP_MD_free() and EVP_MD_meth_free() to call new common evp_md_free_int() function. Refactor EVP_CIPHER_free() and EVP_CIPHER_meth_free() to call new common evp_cipher_free_int() function. Also change some flags tests to explicit test == or != zero. E.g., if (flags & x) --> if ((flags & x) != 0) if (!(flags & x)) --> if ((flags & x) == 0) Only done for those lines where "get0_cipher" calls were made.

The idea is to make it as transparent as possible to call things like EVP_PKEY_CTX_ctrl() with a provider backed EVP_PKEY_CTX, or things like EVP_PKEY_get_bn_param() with a legacy EVP_PKEY. All these sorts of calls demand that we translate between ctrl commands and OSSL_PARAM keys, and treat the arguments appropriately.

2021-02-15Implement EVP_PKEY_param_check_quick() and use it in libsslMatt Caswell
The low level DH API has two functions for checking parameters: DH_check_ex() and DH_check_params_ex(). The former does a "full" check, while the latter does a "quick" check. Most importantly it skips the check for a safe prime. We're ok without using safe primes here because we're doing ephemeral DH. Now that libssl is fully using the EVP API, we need a way to specify that we want a quick check instead of a full check. Therefore we introduce EVP_PKEY_param_check_quick() and use it.

2021-02-07Fix race condition & allow operation cache to grow.Pauli
This fixes a race condition where the index to the cache location was found under a read lock and a later write lock set the cache entry. The issue being that two threads could get the same location index and then fight each other over writing the cache entry. The most likely outcome is a memory leak, however it would be possible to set up an invalid cache entry. The operation cache was a fixed sized array, once full an assertion failed. The other fix here is to convert this to a stack. The code is simplified and it avoids a cache overflow condition.
