Bug Description

[Impact]

* Suricata is not able to start without changes on config files.
When starting the daemon, it tries to detect NLQUEUE support
checking existence of wrong procfs file.

* On precise it is not able to start out-of-the-box after the
change above. Suricata-debian.yaml points to wrong
reference.config file.

* This change fixes LP #1250439.

[Test Case]

* Steps

    Install "suricata" package with apt-get.
    Set RUN to yes on /etc/default/suricata.
    Make sure nfnetlink_queue and nfnetlink modules are not loaded.
    Try to start suricata service and it will complain about no NFQUEUE.
    Modprobe nfnetlink_queue and try to start suricata again.
    You cannot because file being checked is /proc/net/netfilter/nf_queue.

* On precise:

Wrong auto-generated reference on /etc/suricata/suricata-debian.yaml.
Package silently refuses to start even after fixing service init script.

[Regression Potential]

* Since this problem exists on upstream and on all Ubuntu versions, it
is most likely that customers using this package have already fixed
init script.

* Since customers tend to write their own suricata rules, it is most
likely that cutomers have already fixed default rules file.

* Regression would make suricata daemon not to start (just like now).

[Other Info]

Suricata in newer kernels (3.5 and upper) will complain like this:

* NFQUEUE support not found !
* Please ensure the nfnetlink_queue module is loaded or built in kernel

although nfnetlink_queue is loaded:

lsmod | grep nfnetlink_queue
nfnetlink_queue 17557 3
nfnetlink 13983 5 nf_conntrack_netlink,nfnetlink_queue

This happens because /etc/init.d/suricata does this check:

check_nfqueue() {
if [ ! -e /proc/net/netfilter/nf_queue ]; then
    log_failure_msg "NFQUEUE support not found !"
    log_failure_msg "Please ensure the nfnetlink_queue module is loaded or built in kernel"
    exit 5
fi
}

Nevertheless this only works in pre3.5 kernels as newer kernels have supressed ip_queue , in benefit of libnetfilter_queue.

Thus the script should check that nor /proc/net/netfilter/nf_queue nor /proc/net/netfilter/nfnetlink_queue existed.

Fix seems ok since this type of detection is being used on similar projects.

1) Proposed patch for Debian sid:

2) Proposed patch merge for Ubuntu development on:

https://code.launchpad.net/~inaddy/ubuntu/trusty/suricata/lp-1250439/+merge/216963

3) Created one diff for precise, with a minor correction on default init configuration file (reference.config).
* fix-precise-suricata_1.1.1-1.diff

4) Created one diff for saucy equal to upstream patch proposal.
* fix-saucy-suricata_1.4.3-1.diff

5) Created one diff for trusty equal to upstream patch proposal.
* fix-trusty-suricata_1.4.7-1

Packages have been tested and daemon can init out-of-the-box on all versions.
(remembering to set RUN=yes on /etc/default/suricata)

I have tested this package on precise and saucy , and it solves the issue (suricata will start as long as you have the needed kernel module loaded)

I'd like to see this also verified in Trusty, rather than have the possibility of users upgrading and encountering a regression.

Unfortunately Utopic is already EOL and Vivid will be EOL tomorrow, not enough time for a SRU.
