Hello,
the comment does not match the code in this spot:
It reads "above rcv_nxt" but it does "greater than or equal to".
/* The sequence number must be within the window (above rcv_nxt
and below rcv_nxt + rcv_wnd) in order to be further
processed. */
/*if (TCP_SEQ_GEQ(seqno, pcb->rcv_nxt) &&
TCP_SEQ_LT(seqno, pcb->rcv_nxt + pcb->rcv_wnd)) {*/
if(TCP_SEQ_BETWEEN(seqno, pcb->rcv_nxt, pcb->rcv_nxt + pcb->rcv_wnd
- 1)){
if (pcb->rcv_nxt == seqno) {
This was also the case in the old code (between comments).
Is the code, or is the comment correct?
Regards,
Leon.
