Suricata Development Update

SuricataWith the holidays approaching and the 1.4.7 and 2.0beta2 releases out, I thought it was a good moment for some reflection on how development is going.

I feel things are going very well. It’s great to work with a group that approaches this project from different angles. OISF has budget have people work on overall features, quality and support. Next to that, our consortium supporters help develop the project: Tilera’s Ken Steele is working on the Tile hardware support, doing lots optimizations. Many of which benefit performance and overall quality for the whole project. Tom Decanio of Npulse is doing great work on the output side, unifying the outputs to be machine readable. Jason Ish of Emulex/Endace is helping out the configuration API, defrag, etc. Others, both from the larger community and our consortium, are helping as well.


At our last meetup in Luxembourg, we’ve spend quite a bit of time discussing how we can improve the quality of Suricata. Since then, we’ve been working hard to add better and more regression and quality testing.

We’ve been using a Buildbot setup for some time now, where on a number of platforms we do basic build testing. First, this was done only against the git master(s). Eric has then created a new method using a script call prscript. It’s purpose is to push a git branch to our buildbot _before_ it’s even considered for inclusion.

Recently, with cooperation of Emerging Threats, we’ve been extending this setup to include a large set of rule+pcap matches that are checked against each commit. This too is part of the pre-include QA process.

There are many more plans to extend this setup further. I’ve set up a private buildbot instance to serve as a staging area. Things we’ll be adding soon:
– valgrind testing
– DrMemory testing
– clang/scan-build
– cppcheck

Ideally, each of those tools would report 0 issues, but thats hard in practice. Sometimes there are false positives. Most tools support some form of suppression, so one of the tasks is to create those.

We’ve spend some time updating our documents regarding contributing to our code base. Please take a moment to a general contribution page, aimed at devs new to the project.

Next to this, this document describes quality requirements for our code, commits and pull requests.

Suricata 2.0

Our roadmap shows a late January 2.0 final release. It might slip a little bit, as we have a few larger changes to make:
– a logging API rewrite is in progress
“united” output, an all JSON log method written by Tom Decanio of Npulse [5]
app-layer API cleanup and update that Anoop is working on [6]

Wrapping up, I think 2013 was a very good year for Suricata. 2014 will hopefully be even better. We will be announcing some new support soon, are improving our training curicullum and will just be working hard to make Suricata better.

But first, the holidays. Cheers!

Suricata development training update

The Suricata development training at RAID 2012 next week is going to happen, so please all RSVP. It’s free!

If you’re planning to attend, please let me know what topics you are interested in. We have core devs in the room, so we can go hardcore on everything from the threading to packet capture to CUDA to pattern matching… also more straightforward stuff like extending Suricata with new keywords, log modules, etc.

Let me know! Oh and RSVP! 🙂

Suricata development training

We’re considering to offer a Suricata development training day around the next OISF brainstorm meeting. That would be in Amsterdam around the RAID conference, in early September.

Topics we could cover:

– code/development overview
– create/extend detect module
– create/extend output module
– app layer module
– proto detection
– …

The training would probably be free as it’s an excercise for us as well, so we’d just want honest feedback in return 🙂

Nothing is set in stone at this point, but I wanted to throw the idea around already. If you’re interested in joining this session, please let us know! If there is enough interest we may just make this happen!
