I’d like to checkpoint/restore the TLS session in conjunction with TCP_REPAIR. When we checkpoint the kTLS session, we need to pick the record sequence number or any other session information from kernel. For TX side, it is already supported (getsockopt TLS_TX), so I’m wondering why RX side is missing. Is there any technical difficulty or it will never supported in future?
