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)

Add support for passing the libctx to the config loader The self tests for the fips module are triggered on startup and they need to know the core's libctx in order to function correctly. As the provider can be autoloaded via configuration it then needs to propagate the callers libctx down to the provider via the config load. Note that OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CONFIG, ..) is still called, but will only load the default configuration if the OPENSSL_CONF environment variable is set.
