/* Define states of a socket to tracking messages sending to and from the
|
|
* socket.
|
|
*
|
|
* These states are based on rfc9293 with some modifications to support
|
|
* tracking of messages sent out from a socket. For example, when a SYN is
|
|
* received, a new socket is transiting to the SYN_RECV state defined in
|
|
* rfc9293. But, we put it in SYN_RECV_SENDING_SYN_ACK state and when
|
|
* SYN-ACK is sent out, it moves to SYN_RECV state. With this modification,
|
|
* we can track the message sent out from a socket.
