int ossl_provider_activate(OSSL_PROVIDER *prov);
Add functions to see if a provider is available for use. Public function OSSL_PROVIDER_available() takes a library context and a provider name, and returns 1 if it's available for use, i.e. if it's possible to fetch implementations from it, otherwise 0. Internal function ossl_provider_activated() returns 1 if the given OSSL_PROVIDER is activated, otherwise 0. To make this possible, the activation of fallbacks got refactored out to a separate function, which ended up simplifying the code.

Replumbing: give the possibility for the provider to create a context OSSL_provider_init() gets another output parameter, holding a pointer to a provider side context. It's entirely up to the provider to define the context and what it's being used for. This pointer is passed back to other provider functions, typically the provider global get_params and set_params functions, and also the diverse algorithm context creators, and of course, the teardown function. With this, a provider can be instantiated more than once, or be re-loaded as the case may be, while maintaining instance state.

Prepare EVP_MAC infrastructure for moving all MACs to providers Quite a few adaptations are needed, most prominently the added code to allow provider based MACs. As part of this, all the old information functions are gone, except for EVP_MAC_name(). Some of them will reappear later, for example EVP_MAC_do_all() in some form. MACs by EVP_PKEY was particularly difficult to deal with, as they need to allocate and deallocate EVP_MAC_CTXs "under the hood", and thereby implicitly fetch the corresponding EVP_MAC. This means that EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count may need to be incremented and decremented as part of the allocation or deallocation of the EVP_MAC_CTX. It may be that other provider based EVP operation types may need to be handled in a similar manner.

Rename provider and core get_param_types functions It was argued that names like SOMETHING_set_param_types were confusing, and a rename has been proposed to SOMETHING_settable_params, and by consequence, SOMETHING_get_param_types is renamed SOMETHING_gettable_params.

This is platform specific module_path = /opt/openssl/modules/foo.so # Whether it should be automatically activated. Value is unimportant activate = whatever # Anything else goes as well, and becomes parameters that the # provider can get what = 1 # sub-sections will be followed as well ever = ever_section [ever_section] cookie = monster All the configurations in a provider section and its sub-sections become parameters for the provider to get, i.e. the "foo" provider will be able to get values for the following keys (with associated values shown): identity => myfoo module_path => /opt/openssl/modules/foo.so activate => whatever what => 1 ever.cookie => monster Reviewed-by: Paul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/8549)
