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 pr=
ovider framework?
Thanks,
Ramkumar Balu
