Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around our FOO_up_ref functions and opaque libssl types. This causes some difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER checks for 1.1.0 APIs we have will be wrong. Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can break external projects. It is common to implement a compatibility version of an accessor under #ifdef as a static function. This then conflicts with our headers if we, unlike OpenSSL 1.0.2, have this function. This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds enough accessors for software with 1.1.0 support already. The hope is this will unblock hiding SSL_CTX and SSL_SESSION, which will be especially useful with C++-ficiation. The cost is we will hit some growing pains as more 1.1.0 consumers enter the ecosystem and we converge on the right set of APIs to import from upstream. It does not remove any 1.0.2 APIs, so we will not require that all projects support 1.1.0. The exception is APIs which changed in 1.1.0 but did not change the function signature. Those are breaking changes. Specifically: - SSL_CTX_sess_set_get_cb is now const-correct. - X509_get0_signature is now const-correct. For C++ consumers only, this change temporarily includes an overload hack for SSL_CTX_sess_set_get_cb that keeps the old callback working. This is a workaround for Node not yet supporting OpenSSL 1.1.0. The version number is set at (the as yet unreleased) 1.1.0g to denote that this change includes https://github.com/openssl/openssl/pull/4384.
