OpenSSL is a development tool designed to implement the SSL and TLS cryptographic protocols in your projects. The library is developed as open source and can be used on multiple operating systems Git - openssl.git/commit Don't allow too many consecutive warning alerts Certain warning alerts are ignored if they are received. This can mean that no progress will be made if one peer continually sends those warning alerts. Implement a count so that we abort the connection if we receive too many. Issue reported by Shi Lei.
