Eric Leblond fb4be6199f af-packet: change option name
This patch changes the option name. af-packet long option is
now used instead of -a to mimic pfring behaviour.

This patch improves the standard parsing of the command line.
Running
 suricata -c suricata.yaml --af-packet
will start a suricata running in AF_PACKET mode listening on all
interfaces defined in the suricata.yaml configuration file. The
traditionnal syntax:
 suricata -c suricata.yaml --af-packet=ppp0
will start a suricata listening on ppp0 only.

Eric Leblond fbca1a4e6b af-packet: multi interface support
This patch adds multi interface support to AF_PACKET. A structure
is used at thread creation to give all needed information to the
input module. Parsing of the options is done in runmode preparation
through a dedicated function which return the configuration in a
structure usable by thread creation.

Eric Leblond e80b30c082 af-packet: finalize code
This patch handles the end of AF_PACKET socket support work. It
provides conditional compilation, autofp and single runmode.

It also adds a 'defrag' option which is used to activate defrag
support in kernel to avoid rx_hash computation in flow mode to fail
due to fragmentation.

This patch contains some fixes by Anoop Saldanha, and incorporate
change following review by Anoop Saldanha and Victor Julien.

AF_PACKET support is only build if the --enable-af-packet flag is
given to the configure command line. Detection of code availability
is also done: a check of the existence of AF_PACKET in standard
header is done. It seems this variable is Linux specific and it
should be enough to avoid compilation of AF_PACKET support on other
OSes.
Compilation does not depend on up-to-date headers on the system. If
none are present, wemake our own declaration of FANOUT variables. This
will permit compilation of the feature for system where only the kernel
has been updated to a version superior to 3.1.

Victor Julien 820b0ded82 Add per packet profiling.
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv

Example output of summary stats:

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 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.

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.
