[lwip-devel] [task #7675] Enable to refuse data on a TCP_EVENT_RECV call

[Simon Goldschmidt]

Follow-up Comment #4, task #7675 (project lwip):

Hmm, that sounds like it could work (although the pbuf_ref(recv_data) is not
really needed).

My solution (first calling pcb->recv and don't ack / stop to process the
segment if pcp->recv returns an error) is really far more complex:
TCP_EVENT_RECV would have to be called from tcp_receive instead of tcp_input
for that (which would also be cleaner for debugging, I think). I wouldn't want
to change that now that we have 1.3.0 nearly finished...
