/*
|
||||
说明: 测试前提:
|
||||
1、之前必须有相应的流经过,而且链接跟踪必须没有老化,否则
|
||||
根据五元组是获取不到ct的,获取不到ct,就无法设置ct里的aid
|
||||
比如tcp,比如在调用之前要先建立三次握手,只要状态为ESTABLISHED
|
||||
则ct不会老化.
|
||||
2、根据五元组获取到ct之后,必须有相应的流经过，才会找到
|
||||
对应的ct,才能将之前设置的aid查找出来.
|
||||
测试步骤
|
||||
1、加载conntrack_api.ko
|
||||
2、建立tcp三次握手,看状态为ESTABLISHED
|
||||
3、test中的设置aid的函数dpi_set_aid_test_tcp放在init中
|
||||
在加载模块的时候只运行一次,get_aid_test放在netfilter的钩子
|
||||
中,因为这个在将来业务模块调用时会由报文触发
|
||||
4、加载test.ko(此处的test为在init函数中只设置一次aid,所以
|
||||
如果未设置tcp三次握手，也就是说没有在链接跟踪中记录到
|
||||
这个五元组对应的流,则test找不到ct,设置aid失败;
|
||||
如果dpi_set_aid_test_tcp放在netfilter的钩子中,由报文触发,
|
||||
则加载test.ko和链接跟踪创建的时序就无所谓了)
|
||||
|
||||
keypoint: 流触发建立链接跟踪和test的加载顺序,如果设置aid
|
||||
放在init,只设置一次,那么执行顺序很重要;如果设置aid在netfilter
|
||||
钩子中,由报文触发,又不断有这个流经过,则执行顺序无所谓,因为只
|
||||
要找到有一次,设置进去就可以了
|
||||
|
||||
测试的时候可以写个tcp程序,server端一直循环recv,不close fd,
|
||||
client端也不close fd,等待终端输入调用send;三次握手创建ct,后续
|
||||
查询靠send触发.
|
||||
|
||||
TCP报文记录链接跟踪的前提是建立三次握手成功,如果单方面打流是
|
||||
不行的.但是UDP可以单方面打流来创建ct.

# **安全网关项目产品代码仓库**
|
||||
## **简介**
|
||||
  安全网关项目产品侧仓库，主要存放应用与安全网关设备上的应用、内核等相关功能的代码。
|
||||
## **目录结构**
|
||||
<pre>
|
||||
Product 安全网关产品源代码主目录
|
||||
├── build Makefile和编译脚本目录
|
||||
├── common 公共代码/头文件/配置文件 目录
|
||||
├── modules linux内核态源代码目录
|
||||
│ └── demo 内核态驱动程序 demo 目录
|
||||
└── user 用户态源代码目录
|
||||
└── demo 用户态应用程序 demo 目录
|
||||
</pre>
|
||||
|
||||
>#### **注意事项：**
|
||||
>1. 内核态功能相关代码存放于 modules 目录下
|
||||
>2. 用户态功能相关代码存放与 user 目录下
|
||||
>3. 每个独立的功能以子目录方式存放到适当的目录下
|
||||
>4. user 与 modules 目录中共有的源代码和头文件以及配置文件必须存放到 common 目录中
|
||||
>5. 不得把相同功能、相同定义、相同配置的内容独立放到各自的 user 和 modules 目录中
|
||||
|
||||
## **编译方法**
|
||||
#### 1. 从仓库获取最新代码
|
||||
<code>git clone https://git.komect.net:SDX/vBRAS.git</code>
|
||||
或
|
||||
<code>git pull</code>
|
||||
|
||||
#### 2. 安装必要软件(UBuntu)
|
||||
<code>sudo ./fsl-qoriq-glibc-x86_64-fsl-toolchain-aarch64-toolchain-2.4.1.sh
|
||||
sudo apt-get -y install git u-boot-tools device-tree-compiler autoconf curl flex
|
||||
sudo apt-get -y install automake dh-autoreconf libssl-dev openssl libpcap-dev bc
|
||||
sudo apt-get -y install python-pip qemu-utils libncurses5-dev python-crypto bison
|
||||
</code>
|
||||
|
||||
#### 3. 安装 linux 内核源代码
|
||||
<code>sudo mkdir -p /opt/fsl-kernel /opt/fsl-kernel/arm64 /opt/fsl-kernel/x86
|
||||
sudo chmod 777 /opt/fsl-kernel -R
|
||||
cp ./vBRAS/Platform/kernel/linux-4.9.140.tar.gz /opt/fsl-kernel
|
||||
cd /opt/fsl-kernel
|
||||
tar -xvaf ./linux-4.9.140.tar.gz ./
|
||||
cp ./linux-4.9.140 ./x86
|
||||
cp ./linux-4.9.140 ./arm64
|
||||
</code>
|
||||
|
||||
#### 4. 设置环境变量
|
||||
在 ~/.bashrc 文件末尾加上以下几行配置
|
||||
<code>export HUACHENG_LINUX_KERNEL=/opt/fsl-kernel/x86/linux-4.9.140
|
||||
export HUACHENG_ARM64_KERNEL=/opt/fsl-kernel/arm64/linux-4.9.140
|
||||
export SDKTARGETSYSROOT=/opt/fsl-qoriq/2.4.1/sysroots/aarch64-fsl-linux
|
||||
export PATH=/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/sbin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/sbin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/../x86_64-fslsdk-linux/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux-musl:$PATH
|
||||
source ~/.bashrc
|
||||
</code>
|
||||
|
||||
#### 5. 编译内核
|
||||
+ x64_86
|
||||
<code>cd /opt/fsl-kernel/x86/linux-4.9.140 && make -j</code>
|
||||
+ arm64
|
||||
<code>cd /opt/fsl-kernel/arm64/linux-4.9.140 && unset LDFLAS</code>
|
||||
修改 Makefile 文件第 257、258 两行
|
||||
<code>ARCH ?= $(SUBARCH)
|
||||
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)</code>
|
||||
为
|
||||
<code>ARCH ?= arm64
|
||||
CROSS_COMPILE ?= aarch64-fsl-linux-</code>
|
||||
然后运行 make 命令进行编译
|
||||
|
||||
#### 6. 构建系统
|
||||
+ 构建
|
||||
<code>cd vBRAS/Product
|
||||
make</code>
|
||||
</code>
|
||||
+ 清理
|
||||
<code>make OPT=clean</code>
|
||||
+ 安装
|
||||
<code>make OPT=install [DIR=../_install]</code>
|
||||
DIR 环境变量指定了最终安装默认，默认为 ../_install。支持绝对路径以及相对路径。
|
||||
+ 安装目录结构
|
||||
<pre>
|
||||
_install
|
||||
└── debug 系统构建类型 debug/release
|
||||
├── targets 构建可执行程序、驱动安装目录
|
||||
│ ├── ARM64 ARM64 平台的可执行程序、驱动
|
||||
│ └── LINUX Linux 平台的可执行程序、驱动
|
||||
└── targets.debug 构建可执行程序、驱动的对应调试符号信息安装目录
|
||||
├── ARM64 ARM64 平台的可执行程序、驱动调试符号信息
|
||||
└── LINUX ARM64 平台的可执行程序、驱动调试符号信息
|
||||
</pre>
|
||||
+ 编译信息
|
||||
执行 make 命令进行编译结束后，vBRAS/Common/compile.h 文件中保存了当前系统编译信息，可以在代码中直接引用。
|
||||
<code>#define vBRAS_COMPILE_DATE "2019-05-22"
|
||||
#define vBRAS_COMPILE_TIME "11:19:58"
|
||||
#define vBRAS_COMPILE_MAJOR "20190522"
|
||||
#define vBRAS_COMPILE_SUB "111958"
|
||||
#define vBRAS_COMPILE_BY "hx"
|
||||
#define vBRAS_COMPILE_HOST "hx-ubuntu"
|
||||
#define vBRAS_GIT_TAGS "vBRAS1.0-20181213-stable-159-g1b4c69da2-dev"
|
||||
#define vBRAS_GIT_VERS "1b4c69da2d9cd6d133075f2fd96fbe0ac220fb72"
|
||||
</code>
|
||||
vBRAS_GIT_TAGS 记录了当前源码在 gitlab 服务器上面的分支信息
|
||||
vBRAS_GIT_VERS 记录了当前源码在 gitlab 服务器上面的版本信息
