+Subject: [PATCH] engine: Only register those algos specified with
+ default_algorithms
+
+As part of OpenSSL initialization, the engine(s) configured in the OpenSSL
+config file are loaded, and its algorithms (methods) are registered according
+to the default_algorithms setting.
+
+However, later during initialization, ENGINE_register_all_complete() is called
+which unconditionally registered all algorithms (methods) of the loaded engines
+again, unless the engine flag ENGINE_FLAGS_NO_REGISTER_ALL is set.
+
+Set the ENGINE_FLAGS_NO_REGISTER_ALL flag during IBMCA engine initialization
+to avoid unconditional registration of all algorithms. We only want to register
+algorithms specified in the default_algorithms configuration setting.
+
+Note that if the default_algorithms setting is omitted in the OpenSSL config
+file, then no algorithms will be registered.
