| H A D | tcp_timer.h | diff 264321 Thu Apr 10 16:15:44 MDT 2014 jhb Currently, the TCP slow timer can starve TCP input processing while it walks the list of connections in TIME_WAIT closing expired connections due to contention on the global TCP pcbinfo lock. To remediate, introduce a new global lock to protect the list of connections in TIME_WAIT. Only acquire the TCP pcbinfo lock when closing an expired connection. This limits the window of time when TCP input processing is stopped to the amount of time needed to close a single connection.
