Description

When rate_filter set with "timeout" longer than "seconds" (which is common configuration, see example in http://suricata.readthedocs.io/en/latest/configuration/global-thresholds.html ), program restarts counting of detections when "seconds" expire after last detection, not when "timeout" expires.
In function ThresholdTimeoutCheck(), tv_timeout not taken into consideration, causing program to ignore this parameter and allowing the entry to expire.
