Eric Leblond 1e600c1054 source-nfq: add simulated non-terminal NFQUEUE verdict 
This patch adds a new mode for NFQ inline mode. The idea is to
simulate a non final NFQUEUE rules.
This permit to do send all needed packets to suricata via a simple
FORWARD rule:
    iptables -I FORWARD -m mark ! --mark $MARK/$MASK -j NFQUEUE
And below, we have a standard filtering ruleset.

To do so, suricata issues a NF_REPEAT instead of a NF_ACCEPT verdict and
put a mark ($MARK) with respect to a mask ($MASK) on the handled packet.

NF_REPEAT verdict has for effect to have the packet reinjected at start
of the hook after the verdict. As it has been marked by suricata during
the verdict it will not rematch the initial rules and make his way to
the following classical ruleset.

Mode, mark and mask can be configured via suricata.yaml file with the
following syntax:
   nfq:
     repeat_mode: (false|true)
     mark: $MARK
     mask: $MASK
Default is false to preserve backward compatibility.

Eric Leblond 8330747234 Add multi queue support to NFQ run mode 
This patch adds support for multiple Netfilter queue
in the NFQ run mode. Suricata can now be started on
multiple queue by using a comma separated list of
queue identifier on the command line. The following syntax:
	suricata -q 0 -q 1 -c /opt/suricata/etc/suricata.yaml
will start a suricata listening to Netfilter queue 0 and 1.

Eric Leblond 9c2bdc6d0c Main loop: increase timer. 
Timer in the main loop was of 100 usec. This patch increases it
to 10 ms which should be a reasonnable delay to declare some threads
dead.

Eric Leblond 67b95c8c4d Auto discovery of default packet size 
If default-packet-size is not set, it is possible in some case to
guess a correct value.

If PCAP or PF_RING are used we are linked to a "physical" interface.
Thus, it is possible to get information about the link MTU and
hardware header size. This give us the ability to auto discover a
decent default-packet-size.
If suricata is running under a different running-mode, it will
default to 1514.

Eric Leblond dd038c1906 Modify files to avoid direct pckt payload access 
This patch implements the needed modification of payload access
in a Packet structure to support the abstraction introduced by
the extended data system.
 15 years ago
Eric Leblond e802e1ed16 Modify Packet structure and prepare accessor. 
This patch modifies decode.c and decode.h to avoid the usage
by default of a bigger than 65535 bytes array in Packet structure.
The idea is that the packet are mainly under 1514 bytes size and
a bigger size must be supported but should not be the default.

If the packet length is bigger than DFLT_PACKET_SIZE then the
data are stored in a dynamically allocated part of the memory.

To ease the modification of the rest of the code, functions to
access and set the payload/length in a Packet have been introduced.

The default packet size can be set at runtime via the default-packet-size
configuration variable.

Issue at the moment with pkts being ejected during shutdown -- at the moment we
ignore any packets that are not of link type Ethernet.

Victor Julien 70b32f7380 First stab at creating a stateful detection engine. 
Stateful detection for app layer detection keywords, except uricontent. Stores it's partial results in the flow structure. Other modifications:

- Generalize transaction tracking, logging and inspection.
- Adapt http and dcerpc to use the new transaction handling.
- Stream engine now always notifies app layer of a stream eof.
