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

[Simon Goldschmidt]

Follow-up Comment #4, bug #26251 (project lwip):

According RFC 793 (although that is somewhat outdated), there is more to do
in TIME_WAIT, we should also

- send RST on SYN,
- ACK a FIN and reset pcb->tmr
- ACK acceptable seqno (unless RST set)

Thus leaving pcb->rcv_nxt as it is might make sense, since we already have
received all data we expect.

Not calling tcp_output() twice is also a good idea :-)
