2023-09-04Implement dupctx for chacha20 cipherNeil Horman
Implement the dupctx method for the chacha20 cipher, so that EVP_PKEY_CTX_copy works Its pretty straightforward, its basically just a memdup. Checking the pointers that might need fixing up: in PROV_CHACHA20_CTX all members are statically declared, so memduping should be fine in PROV_CHACHA20_CTX->base (PROV_CIPHER_CTX): Non statically declared members: *tlsmac needs to get memduped to avoid double free conditions, but only if base.alloced is set *hw pointer is always assigned to the chacha20_hw global variable, so can be left alone *libctx can be left alone as provctx is always NULL in chacha20_newctx *ks appears unused by chacha20, so can be ignored Fixes #20978 Reviewed-by: Richard Levitte <levitte@openssl.org> Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Shane Lontis <shane.lontis@oracle.com> Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/21878)

The PROV_R codes can be returned to applications so it is useful to have some common set of provider reason codes for the applications or third party providers.

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)
