Description szander 2018-08-16 23:36:51 UTC
When I use TLS 1.1 or TLS 1.2 the first request that is send to the server is completely garbage (looks like some random bits from memory rather than a HTTP request). Subsequent requests to the same server work fine. I'm not sure what precisely the issue is but I noted that core_ssl_connect() is written such that httperf can interleave other stuff while connecting. With a more "atomic" connect loop the problem is gone on my test machine: 

        while ((ssl_err = SSL_connect(s->ssl)) == -1) {
                int reason = SSL_get_error(s->ssl, ssl_err);

                if (reason != SSL_ERROR_WANT_READ &&
                    reason != SSL_ERROR_WANT_WRITE) {
                            "%s: failed to connect to SSL server (err=%d, reason=%d)\n",
                            prog_name, ssl_err, reason);
