OpenSSL 3 TLS cipher pipelining support with providers

[Ramkumar Balu <rbalu@xxxxxxxxxxx>]

Greetings,

 

Is there any specific reason why pipelining is not supported with providers?

I can see below code in ssl/record/ssl3_record.c

 

        if (provided) {

            int outlen;

 

            /* Provided cipher - we do not support pipelining on this path */

            if (n_recs > 1)  {

                SSLfatal(s, SSL_AD_INTERNAL_ERROR, ERR_R_INTERNAL_ERROR);

                return 0;

            }

 

As a provider author, I’m trying to figure out a way to support pipelining in the implementation. Is there a future plan to add pipeline support in provider framework?

 

Thanks,

Ramkumar Balu
