Package: knockd Version: 0.5-3 Severity: importantIn libpcap 1.5.3 a change was introduced that is causing knockd to use an unreasonably large amount of CPU time. Previously, CPU usage was at 0% - with newer libpcap it's at 5% (on an E5-1620v2 3.7GHz CPU).
Jessie uses libpcap 1.6 and is therefore affected. This has been fixed upstream in 0.7; see https://github.com/jvinet/knock/issues/9 for details.
Perhaps the proposed package in #761853 can be used for a new upload?
