Bug #623
closed1.4b2 core dump with pf_ring and PAE kernel
Description
When running under CentOS 5.8 kernel 2.6.18-308.16.1.el5PAE with PF_RING support compiled in, Suricata dumps core. If I boot into 2.6.18-308.16.1.el5, it runs without issue, but of course most of my RAM doesn't show up.

It runs without issue if I compile it without PF_RING support.

Hi,
Without PAE kernel runs fine as well, correct?
What is your kernel version?
thanks
Updated by Peter Manev almost 12 years ago
I am sorry - 2.6.18 - just saw that.
I noticed that you use two interfaces:
LD_LIBRARY_PATH=/opt/suricata/lib:/opt/pfring/lib /opt/suricata/bin/suricata --pfring-int=eth4 --pfring-int=eth5 --pfring-cluster-id=99 --pfring-cluster-type=cluster_flow -c /opt/suricata/etc/suricata.yaml
Does the problem go away when you use just one?(with PAE)
Are the interfaces bridged?
thank you
Updated by Matt Carothers almost 12 years ago
Yes, it still crashes if I use a single interface. It also still crashes if I don't use PF_RING. E.g. if I start it with -i instead of --pfrint-int.
Updated by Matt Carothers almost 12 years ago
Oh, and the interfaces are not bridged. They are load balanced, however. Both interfaces will see traffic from the same clients, though an individual session will always stay on one interface or the other.

Is it possible for you to provide the binary to download ?
Updated by Matt Carothers almost 12 years ago
Sure, here you go: https://dl.dropbox.com/u/97846692/suricata-1.4b2-pfring.tar.bz2
That's Suricata itself as well as the pf_ring libraries and kernel module.

OK. It looks like a PF_RING issue as the crash occurs inside pf_ring_open.
What is the version of PF_RING ?
There's something I don't like in the way you run suricata: you listen on 2 interface with the same cluster-id.
So here's two things I would like you to try: * Start suricata with one interface * Start suricata with the two interfaces and set the cluster-id to separate values inside the yaml.
For last run you should have something like this inside the YAML:
pfring:
- interface: eth4
threads: 1
cluster-id: 99
cluster-type: cluster_flow
- interface: eth5
threads: 1
cluster-id: 98
cluster-type: cluster_flow
By the way in this case, you should be able to start suricata with
suricata --pf-ring

Ok, that's fixed it. I was using 5.5.0, which is the latest stable version. I compiled a new kernel module from svn, and that cleared up the problem. Thanks!
