We're happily taking patches and other contributions. Please see https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Contributing for how to get started.
-Suricata is a complex piece of software dealing with mostly untrusted input. Mishandling this input will have serious consequences: in IPS mode a crash may knock a network offline; in passive mode a compromise of the IDS may lead to loss of critical and confidential data; missed detection may lead to undetected compromise of the network. In other words, we think the stakes are pretty high, especially since in many common cases the IDS/IPS will be directly reachable by an attacker.

For this reason, we have developed a QA process that is quite extensive. A consequence is that contributing to Suricata can be a somewhat lengthy process.
