How can I know what/why openssl is sending control data?
I have this Node addon that uses TLS 1.2 to communicate. I'm sending a large file transfer (100M), which is chunked into 8100 byte blocks and sent on websocket protocol. It's additionally chunked into 4327 byte blocks (which after encoding is 4356 bytes or 1452*3) All of the data is encoded into blocks and queued to transfer before I have a problem.
After some amount of data transfer OpenSSL starts sending 31 byte control packets after basically each block received... when the other side receives that data it doesn't do anything, but the ssl layer does stop giving me completed packets (instead opting to generate 31 byte packets) when the other side receives those, it doesn't do anything.... (doesn't generate control sends back).
Ad I mentioned all of the pendijng data is already queued to send, so even if I received a control packet and it generated a response it wouldn't get received for quite some time.
I don't have control over what version of SSL is being used... but this current test is 1.0.1m
It's variable by the time it starts sending 31 byte packets... Also depends on the connection; although at this time I'm able to generate the problem on localhost... I was able to transfer from a remote server to myself with no issues...
