Description

===========

Bundled openSSL (openssl-1.0.1u) source codes to compile statically instead of yaSSL,

then MySQL server can support TLSv1.2 SSL protocol.

For the compatibility, we supply new parameter '--tls-version' to control how to decide the

supportable TLS version.

If compiled with openSSL, then tls-version default value 'TLSv1, TLSv1.1, TLSv1.2'

If compiled with yaSSL, then tls-version default value 'TLSv1, TLSv1.1'

Also the added cmake option: DWITH_SSL=openssl means that openssl was built statically.

Compatibility

=============

The TLS Protocol version matrix:

-----------------------------------------------------------------------

                    Pre_Server   Post_yaSSL_Server  Post_openSSL_Server

Pre_Client          TLSv1.0      TLSv1.0            TLSv1.0

Post_yaSSL_Client   TLSv1.0      TLSv1.1            TLSv1.1

Post_openSSL_Client TLSv1.0      TLSv1.1            TLSv1.2
