Follow-up Comment #7, bug #27771 (project lwip):

No, the test in tcp_update_rcv_ann_wnd should look like this (second clause
added):

  if (TCP_SEQ_GEQ(new_right_edge, pcb->rcv_ann_right_edge + pcb->mss) ||
      TCP_SEQ_GEQ(new_right_edge, pcb->rcv_ann_right_edge + TCP_WND / 2)) {


i.e. if you change pcb->rcv_ann_wnd to TCP_WND you'd be right.
