[lwip-devel] [bug #26251] RST process in TIME_WAIT TCP state

[Simon Goldschmidt]

Follow-up Comment #2, bug #26251 (project lwip):

Hmm, RFC1337 recommends to *ignore* RST segments in TIME-WAIT state, I doubt
that this means sending an ACK for this.

I guess to implement that recommendation, we should add this code at the
start of tcp_timewait_input():

if((TCPH_FLAGS(tcphdr) & TCP_RST) {
  /* RFC 1337: ignore RST segments in TIME_WAIT */
  return ERR_OK;
}

Also, I think this can be targeted to 1.3.2.
