Eric Leblond f328e18d59 defrag: fix some integer type warning. 12 years ago
Eric Leblond b1b4cd2729 defrag: really use 'max-frags' variable.
The 'max-frags' variable was not used and the 'trackers' variable was
not documented. This patch fixes the two issues.

Eric Leblond 6480cd1b9c Teredo tunnel supports
This patch should fix #480 by adding the support of Teredo tunnel.
The IPv6 content of the tunnel will be parsed in a similar way as
what is done the GRE tunnel. Signatures will then be matched on the
IPv6 content.

Eric Leblond 2c57275921 nfq: implement "fail-open" support.
On linux >= 3.6, you can use the fail-open option on a NFQ queue
to have the kernel accept the packet if userspace is not able to keep
pace.

Please note that the kernel will not trigger an error if the feature is activated
in userspace libraries but not available in kernel.

This patch implements the option for suricata by adding a nfq.fail-open
configuration variable which is desactivated by default.

Eric Leblond 452d3c4308 tm-thread: exit loop if suri want to quit 12 years ago
Eric Leblond f389a1201f tm-thread: run thread init function sequentially.
On some setup you want to run each thread init function sequentially.
For example, if I use flow_cpu load balancing on AF_PACKET, my target
is to have CPU 0 (first socket in the group) to be link with the
thread 0 in detect cpu set (first thread to be initialised). A good
way to achieve this is to run only one thread init function at a time
to avoid any possible race condition.

Eric Leblond 11c3167583 stream-tcp: no checksum alert if validation is off
This patch disables checksum alert if checksum-validation is set
to no in the configuration file. Without this patch, when parsing
a pcap which checksum offloading, it was not possible to get rid
of event caused by checksum validation.

Anoop Saldanha 64fad5b36e Update fast_pattern engine to not use negated content as fast_pattern if we have non-negated content in the sig.
Noticing a good spike in perf with et_pro ruleset.

Thanks to Will Metcalf for the suggestion.

Anoop Saldanha fe4c66461f bug #466 - Updated getticks() to serialize execution of rdtsc with cpuid 12 years ago
Anoop Saldanha 41bb3b95f9 bug 508 - List (ack | cwr | ecn) combination to be accepted by our stream engine.
This isn't a perfect solution.  More like we have patched this for the case we
are in tcp's established state.  The right solution would be to accept states
based on the presence(using operator OR) of certain flags in the tcp header,
rather than list out all possible flag combinations.

Eric Leblond a369f8c359 af-packet: loop on ring if there is data to read.
This patch should bring some improvements by looping on the
ring when there is some data available instead of getting back
to the poll. It also fix recovery in case of drops on the ring
because the poll command will not return correctly in this case.

Eric Leblond 4df509f87a defrag: use IP ID in hash
This patch fixes the collision issue observed on an intensive network
trafic. When there is fragmentation it is the case for all data
exchanged between two hosts. Thus using a hash func only involving
IP addresses (and protocol) was leading to a collision for all
exchanges between the hosts. At a larger scale, it was resulting in
a packet loss. By using the IP ID instead of the protocol family, we
introduce a real difference between the trackers.

Eric Leblond a3465fb971 Rename 'worker' running mode to 'workers'
This patch renamed the 'worker' running mode into 'workers'. Thus,
there is only one name in Suricata for the same thing. Backward
compatibility is ensured by replacing "worker" by "workers" when
the old name is used. A warning is printed in the log when the old
name is used.
