I have a DTLS 1.2 server based on last master (commit d196305aa0de1fc38837c27cb1ea6e60af9dd98d) I try to add ocsp stapling support (based on code in s_server.c). Basicaly in my callback I set the OCSP response by: if (SSL_set_tlsext_status_ocsp_resp(s,dataPtr,respLen) == 0) { return SSL_TLSEXT_ERR_NOACK; } else { return SSL_TLSEXT_ERR_OK; } but if my server manage to get an OCSP response it crash with this message: ssl/statem/statem_dtls.c:127: OpenSSL internal error: assertion failed: s->init_num == (int)s->d1->w_msg_hdr.msg_len + DTLS1_HM_HEADER_LENGTH Any clue? -- Julien Vermillard -------------- next part -------------- An HTML attachment was scrubbed...
