Sowmini Varadhan 10beea7d74 rds: tcp: Set linger when rejecting an incoming conn in rds_tcp_accept_one ... Each time we get an incoming SYN to the RDS_TCP_PORT, the TCP layer accepts the connection and then the rds_tcp_accept_one() callback is invoked to process the incoming connection. rds_tcp_accept_one() may reject the incoming syn for a number of reasons, e.g., commit 1a0e100fb2 ("RDS: TCP: Force every connection to be initiated by numerically smaller IP address"), or because we are getting spammed by a malicious node that is triggering a flood of connection attempts to RDS_TCP_PORT. If the incoming syn is rejected, no data would have been sent on the TCP socket, and we do not need to be in TIME_WAIT state, so we set linger on the TCP socket before closing, thereby closing the socket efficiently with a RST.
