suricata4.1.1增加dpdk数据采集

DPDK_SURICATA-4_1_1

Planning to merge ACL from 3.0 with dpdk 19.11.

Motivation

Create simple DPDK RX-TX to allow packets into SURICATA processing pipeiline mode. First step to speed up suricata open source user space application using DPDK PMD

Things to do

• allow packets to captured by Recieve and Decode threads
• implement SW or HW Symmetric Hashing for reassembled packets.
• flatten the packet buffer for full zero-copy mode.
• use SW or HW ACL for classification on directional rules.

How to Build?

dependency

• https://suricata.readthedocs.io/en/suricata-4.1.2/install.html

version:

software	release
DPDK	dpdk-stable-18.11.1
Suricata	suricata-4.1.4

Build and Run

DPDK 18.11.3

• Download DPDK from dpdk.org.
• Untar DPDK tar file.
• Execute the following commands

 cd <to unatar dpdk folder>
 make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
 export RTE_SDK=$PWD
 export RTE_TARGET=x86_64-native-linuxapp-gcc
 cd x86_64-native-linuxapp-gcc
 make -j 4

• Test the custom build by cross checking examples like helloworld & l2fwd.

modified suricata:

steps	explanation
autoconf	to build the configure script with DPDK support
./configure --enable-dpdk	makes configuration with dpdk
make -j 10	build suricata with 10 threads

How to Run?

command	purpose
./src/suricata --build-info; ./src/suricata --list-runmodes	get suricata version and supported modes
./src/suricata --list-dpdkports	list DPDK available ports
./src/suricata --dpdk=<path to to config>/mysuricata.cfg	Run DPDK suircata with mysuricata.cfg
