Hi, Automatic receive buffer sizing works only for connections in ESTABLISHED state. In tcp_input() auto resizing code is under "if (tp->t_state == TCPS_ESTABLISHED && ...)" branch. This is unfortunate for HAST, which uses one direction connections and shutdown another direction, so the receiving socket is in FIN_WAIT_2 and auto resizing does not work here. Is there some reason why it should be only for connections in ESTABLISHED state or this should be considered as a bug? -- Mikolaj Golub
