Replumbing: add a configuration module for providers This configuration module supports a configuration structure pretty much like the engine configuration module, i.e. something like this: openssl_conf = openssl_init [openssl_init] providers = provider_section [provider_section] # Configure the provider named "foo" foo = foo_section # Configure the provider named "bar" bar = bar_section [foo_section] # Override name given in the provider section identity = myfoo # The exact path of the module. 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)

In OpenSSL builds, declare STACK for datatypes ... ... and only *define* them in the source files that need them. Use DEFINE_OR_DECLARE which is set appropriately for internal builds and not non-deprecated builds. Deprecate stack-of-block Better documentation Move some ASN1 struct typedefs to types.h Update ParseC to handle this. Most of all, ParseC needed to be more consistent. The handlers are "recursive", in so far that they are called again and again until they terminate, which depends entirely on what the "massager" returns. There's a comment at the beginning of ParseC that explains how that works. {Richard Levtte} Reviewed-by: Dmitry Belyavskiy <beldmit@gmail.com> Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/10669)

Refactor OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA This refactors OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA. The assorted objects to be managed by OSSL_LIB_CTX are hardcoded and are initialized eagerly rather than lazily, which avoids the need for locking on access in most cases. Fixes #17116.

Rename OPENSSL_CTX prefix to OSSL_LIB_CTX 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.

Replumbing: add a configuration module for providers This configuration module supports a configuration structure pretty much like the engine configuration module, i.e. something like this: openssl_conf = openssl_init [openssl_init] providers = provider_section [provider_section] # Configure the provider named "foo" foo = foo_section # Configure the provider named "bar" bar = bar_section [foo_section] # Override name given in the provider section identity = myfoo # The exact path of the module. 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)
