Hi,
We have an application which has SCTP connections we have secured the SCTP connections using the openssl DTLS. DTLS is working as expected other than the SCTP events.
We use the API "BIO_new_dgram_sctp" to create a BIO objects and we register a callback function to openssl using API "BIO_dgram_sctp_notification_cb" to populate the SCTP events. I observe that openssl enables only authentication related events, do not enable any other events like association, shutdown etc.
Code snippet from the API "BIO_new_dgram_sctp":
event.sctp_authentication_event = 1;
ret =
setsockopt(fd, IPPROTO_SCTP, SCTP_EVENTS, &event,
sizeof(struct sctp_event_subscribe));
if (ret < 0) {
BIO_vfree(bio);
return (NULL);
}
Is there any specific reason for just enabling the authentication events ?
If yes, is there any way applications register for other events like shutdown, association etc. We have a requirement where based on the SCTP events application executes certain business logic.
Thanks,
