the accecpt() and connect() logic. Contributed by Max Nekludov.
* net/recvfrom.c and net/uip/uip_tcpcallback.c: Fix a leak in the TCP
read-ahead logic. This is a *critical* bug fix!
+ * net/uip/uip_tcpinput.c: Correct an error in the TCP stack. It was
+ incrementing the received sequence number BEFORE determining if the
+ incoming data could be handled. If the data was dropped (usually because
+ there is insufficient buffering space), then no ACK will be sent and the
+ sequence number will be wrong. The end consequence of the bad sequence
+ number was that the when the dropped packet was re-transmitted, it was
+ was ignored because its sequence number looked wrong. Fix was, obviously,
+ to only increment the recevied sequence number if the TCP data was
+ accepted.
