[lwip-devel] [bug #26301] Out of order FIN closes half-closed connection

[Oleg Tyshev]

Follow-up Comment #7, bug #26301 (project lwip):

It should work better here and other places.

case FIN_WAIT_1:
tcp_receive(pcb);
-if (flags & TCP_FIN) {
+if (recv_flags == TF_GOT_FIN) {

Flag TF_GOT_FIN means that FIN segment was received in sequence.
I'll try it and say about results.
