[lwip-devel] [bug #27215] TCP sent() callback gives leagin and trailing 1 byte len (SYN/FIN)

[Simon Goldschmidt]

Update of bug #27215 (project lwip):

                  Status:                    None => In Progress            
             Assigned to:                    None => goldsimon

Follow-up Comment #3:

The attached patch tries to solve this bug by using this condition:

if ((pcb->acked != 1) || ((old_state != SYN_RCVD) &&
    (pcb->state != FIN_WAIT_2) && (pcb->state != TIME_WAIT))) {
  TCP_EVENT_SENT(pcb, pcb->acked, err);
}

thus not calling the sent callback if one byte was acked in a specific state
(or state before calling tcp_process).

Tested with the httpd and a raw api tcp client.

Any objections?
