Victor Julien ba81c4d290 autotools: cleanup
Remove most of the CFLAGS updates from configure. Flags are now (mostly)
set in AM_CLFLAGS.

Update all -DBLAH additions to CFLAGS to use AC_DEFINE([BLAH], ...)

Improve Lua vs LuaJIT checking.

Improve the configure output a bit.

Lots of smaller cleanups.

Eric Leblond 4db0a35f25 tls-store: now a separate module
An design error was made when doing the TLS storage module which
has been made dependant of the TLS logging. At the time there was
only one TLS logging module but there is now two different ones.

By putting the TLS store module in a separate module, we can now
use EVE output and TLS store at the same time.

Victor Julien 04ccfda639 pcap: implement LINKTYPE_NULL
Implement LINKTYPE_NULL for pcap live and pcap file.

From: http://www.tcpdump.org/linktypes.html

"BSD loopback encapsulation; the link layer header is a 4-byte field,
 in host byte order, containing a PF_ value from socket.h for the
 network-layer protocol of the packet.

 Note that ``host byte order'' is the byte order of the machine on
 which the packets are captured, and the PF_ values are for the OS
 of the machine on which the packets are captured; if a live capture
 is being done, ``host byte order'' is the byte order of the machine
 capturing the packets, and the PF_ values are those of the OS of
 the machine capturing the packets, but if a ``savefile'' is being
 read, the byte order and PF_ values are not necessarily those of
 the machine reading the capture file."

DIALLO David b3bf2f9939 Detect: Add Modbus keyword management
Add the modbus.function and subfunction) keywords for public function match in rules (Modbus layer).
Matching based on code function, and if necessary, sub-function code
or based on category (assigned, unassigned, public, user or reserved)
and negation is permitted.

Add the modbus.access keyword for read/write Modbus function match in rules (Modbus layer).
Matching based on access type (read or write),
and/or function type (discretes, coils, input or holding)
and, if necessary, read or write address access,
and, if necessary, value to write.
For address and value matching, "<", ">" and "<>" is permitted.

Based on TLS source code and file size source code (address and value matching).

Ken Steele 497575d38e Add option on Tile-Gx for logging for fast.log alerts over PCIe
When running on a TILEncore-Gx PCIe card, setting the filetype of fast.log
to pcie, will open a connection over PCIe to a host application caleld
tile-pcie-logd, that receives the alert strings and writes them to a file
on the host. The file name to open is also passed over the PCIe link.

This allows running Suricata on the TILEncore-Gx PCIe card, but have the
alerts logged to the host system's file system efficiently. The PCIe API that
is used is the Tilera Packet Queue (PQ) API which can access PCIe from User
Space, thus avoiding system calls.

Created util-logopenfile-tile.c and util-logopen-tile.h for the TILE
specific PCIe logging functionality.

Using Write() and Close() function pointers in LogFileCtx, which
default to standard write and close for files and sockets, but are
changed to PCIe write and close functions when a PCIe channel is
openned for logging.

Moved Logging contex out of tm-modules.h into util-logopenfile.h,
where it makes more sense. This required including util-logopenfile.h
into a couple of alert-*.c files, which previously were getting the
definitions from tm-modules.h.

The source and Makefile for tile-pcie-logd are added in contrib/tile-pcie-logd.

By default, the file name for fast.log specified in suricata.yaml is used as
the filename on the host. An optional argument to tile-pcie-logd, --prefix=,
can be added to prepend the supplied file path. For example, is the file
in suricata.yaml is specified as "/var/log/fast.log" and --prefix="/tmp",
then the file will be written to "/tmp/var/log/fast.log".

Check for TILERA_ROOT environment variable before building tile_pcie_logd

Building tile_pcie_logd on x86 requires the Tilera MDE for its PCIe libraries
and API header files. Configure now checs for TILERA_ROOT before enabling
builing tile_pcie_logd in contrib/tile_pcie_logd
