3.8.13.11 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Andrew Vagin <[email protected]> [ Upstream commit c7781a6e3c4a9a17e144ec2db00ebfea327bd627 ] u32 rcv_tstamp; /* timestamp of last received ACK */ Its value used in tcp_retransmit_timer, which closes socket if the last ack was received more then TCP_RTO_MAX ago. Currently rcv_tstamp is initialized to zero and if tcp_retransmit_timer is called before receiving a first ack, the connection is closed. This patch initializes rcv_tstamp to a timestamp, when a socket was restored. Cc: Pavel Emelyanov <[email protected]> Cc: Eric Dumazet <[email protected]> Cc: "David S.
