PROTON-2535: TLS OpenSSL library: remove BIO on decrypt side for accurate errors and byte counts
> TLS library - false indication of user data in OpenSSL
> ------------------------------------------------------
>
> Key: PROTON-2535
> URL: https://issues.apache.org/jira/browse/PROTON-2535
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.37.0
> Environment: OpenSSL
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
>
> pn_tls_need_decrypt_output_buffers can falsely indicate the availability of user data. For example if there is a handshake failure, BIO_pending can indicate the presence of bytes but BIO_read will return -1 and the appropriate error.
> An application may be fooled into providing a decrypt output buffer that won't be immediately be returned after the next pn_tls_process() step, since no bytes will be read into it.
