Ebpf开发环境准备

#Ebpf

1、系统准备

# Upgrade all packages to newest.
sudo apt update -y && sudo apt upgrade -y

# Change apt mirror，这一步根据自己的网络情况，可以不改，设置国内源加速
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

sudo apt update && sudo apt install apt-utils gnupg ca-certificates apt-transport-https software-properties-common wget -y

#国内清华的源 
#https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
# x86_64:
#sudo sed -i "s@http://.*archive.ubuntu.com@https://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
#sudo sed -i "s@http://.*security.ubuntu.com@https://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
# or arm64:
# sudo sed -i "s@http://.*ports.ubuntu.com@https://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
# sudo apt update -y && sudo apt upgrade -y

# Install apt-utils to make apt run more smoothly
DEBIAN_FRONTEND="noninteractive" sudo apt-get install -y apt-utils python3 python3-pip python2

2、安装pip

# Setup pip mirror
#升级
pip install -U pip 

#设置国内源加速
mkdir ~/.pip 
touch ~/.pip/pip.conf 
echo -e '\n[install]\ntrusted-host=pypi.douban.com\n[global]\nindex-url=http://pypi.douban.com/simple' > ~/.pip/pip.conf
cat ~/.pip/pip.conf 
pip install -U pip

#或者使用下面的方法更简单：
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple 
pip install -U pip 
pip install pytest

3、安装docker

# Install docker
sudo apt-get install docker.io -y
sudo gpasswd -a ${USER} docker
newgrp - docker
sudo service docker restart

quay.io/iovisor/bpftrace:latest
quay.io/iovisor/bpftrace-llvm:bionic_12

# docker images 提供了bpftrace的镜像

4、安装最新版本的Golang

export GOV=1.20.4

wget https://go.dev/dl/go${GOV}.linux-amd64.tar.gz
#wget https://go.dev/dl/go${GOV}.linux-arm64.tar.gz
rm -rf /usr/local/go && sudo mkdir -p /usr/local/go && sudo chmod 777 /usr/local/go 
tar -C /usr/local -xzf go${GOV}.linux-amd64.tar.gz 
export PATH=$PATH:/usr/local/go/bin:$PATH
echo 'PATH="/usr/local/go/bin:$PATH"'>>~/.profile && source ~/.profile

go version

# 直接安装golang,
sudo apt install golang -y
go version
export G0111MODULE=On
export GOPROXY=https://goproxy.cn
or
echo "export G0111MODULE=on"  >> ~/.profile
echo "export GOPROXY=https://goproxy.cn,direct".>> ~/.profile
source ~/.profile

# 查看所有服务状态
service --status-all

5、编码工具

# Install vscode
sudo rm -f /etc/apt/keyrings/packages.microsoft.gpg
wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > packages.microsoft.gpg
sudo install -D -o root -g root -m 644 packages.microsoft.gpg /etc/apt/keyrings/packages.microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64,arm64,armhf signed-by=/etc/apt/keyrings/packages.microsoft.gpg] https://packages.microsoft.com/repos/code stable main" > /etc/apt/sources.list.d/vscode.list'
sudo apt update -y && sudo apt install code -y

6、AOSP与内核

这里对于rock5b或者其它arm64环境不需要安装

# Install the packages needed for AOSP build
DEBIAN_FRONTEND="noninteractive" sudo apt-get install -y git-core gnupg flex bison build-essential \
    zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev \
    x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip \
    fontconfig libncurses5 procps rsync libsqlite3-0

# Install the packages needed for AOSP kernel build
sudo apt install p7zip-full wget curl git tree pkg-config vim -y
sudo apt-get install dialog file python3 python3-pip python2 libelf-dev gpg gpg-agent tree flex bison libssl-dev zip unzip curl wget tree build-essential bc software-properties-common libstdc++6 libpulse0 libglu1-mesa locales lcov --no-install-recommends -y

# Linux kernel内核编译依赖

sudo apt-get install -y fakeroot build-essential devscripts libncurses5 libncurses5-dev

# BCC开箱使用,二级制安装：官方文档

https://github.com/iovisor/bcc/blob/master/INSTALL.md#ubuntu---binary

#最好是通过下面的源码去安装，不要用这个安装。

# Install kernel headers and BCC 不可以与下面的源码同时安装，版本可能不一样。
sudo apt-get install bpfcc-tools linux-headers-$(uname -r)


#卸载，
sudo apt purge bpfcc-tools libbpfcc python3-bpfcc

官方文档源码安装:

https://github.com/iovisor/bcc/blob/master/INSTALL.md#ubuntu---source

# Install kernel headers 
sudo apt-get insntall -y linux-headers-$(uname -r)

# For Focal (20.04.1 LTS)
sudo apt install -y zip bison build-essential cmake flex git libedit-dev \
  libllvm12 llvm-12-dev libclang-12-dev python zlib1g-dev libelf-dev libfl-dev python3-setuptools \
  liblzma-dev arping netperf iperf
  
# For Jammy (22.04)
sudo apt install -y zip bison build-essential cmake flex git libedit-dev \
  libllvm14 llvm-14-dev libclang-14-dev python3 zlib1g-dev libelf-dev libfl-dev python3-setuptools \
  liblzma-dev libdebuginfod-dev arping netperf iperf


# For bcc test
sudo apt-get install -y iperf netperf arping net-tools python-is-python3


# make all packages under ebpf dir

mkdir ebpf && cd ebpf

## bcc python
# cmake .. -DENABLE_LLVM_SHARED=1   编译bcc时使用llvm动态链接库
# git clone -b v0.25.0 https://github.com/iovisor/bcc.git  v0.25版本的bcc

rm -rf bcc
git clone --recursive https://github.com/iovisor/bcc.git
mkdir bcc/build; cd bcc/build
cmake .. -DENABLE_LLVM_SHARED=1
make -j8
sudo make install
cmake -DPYTHON_CMD=python3 -DENABLE_LLVM_SHARED=1 ..
pushd src/python/
make -j8
sudo make install
popd
cd ..

# The tools are installed in /usr/share/bcc/tools.


bcctools=/usr/share/bcc/tools
bccexamples=/usr/share/bcc/examples
export PATH=$bcctools:$bccexamples:$PATH

查看安装

pip list |grep bcc
dpkg  -l |grep bcc
sudo apt purge bpfcc-tools libbpfcc python3-bpfcc

# bcc libbpf-tools

直接编译会报如下错误

/usr/include/linux/errno.h:1:10: fatal error: 'asm/errno.h' file not found#include <asm/errno.h> ^~~~~~~~~~~~~1 error generated.

执行如下命令编译即可：

cd libbpf-tools/
make -j8 BPFCFLAGS="-g -O2 -Wall -I/usr/include/aarch64-linux-gnu"
cd ../../

7、 bpftrace

#直接安装
sudo apt-get install -y bpftrace

源码编译：

https://github.com/iovisor/bpftrace/blob/master/INSTALL.md#ubuntu 先安装依赖：

sudo apt-get install -y \
  bison \
  cmake \

# build bpftrace:
rm -rf bpftrace
# export https_proxy=http://192.168.0.120:7890 http_proxy=http://192.168.0.120:7890 all_proxy=socks5://192.168.0.120:7890
git clone https://github.com/iovisor/bpftrace --recurse-submodules
mkdir bpftrace/build; cd bpftrace/build;
../build-libs.sh
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j8

8、libbpf-bootstrap

git clone --recursive https://github.com/libbpf/libbpf-bootstrap
pushd libbpf-bootstrap/examples/c
make -j8
popd

9、bpftool

git clone --recursive https://github.com/libbpf/bpftool
pushd bpftool/src
make -j8
sudo make install
popd

10、cuttlefish

https://source.android.com/docs/setup/create/cuttlefish-use?hl=zh-cn

https://android.googlesource.com/device/google/cuttlefish/

在rock5b上执行：编译模拟器：

sudo apt install -y git devscripts config-package-dev debhelper-compat golang curl
git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
for dir in base frontend; do
  cd $dir
  debuild -i -us -uc -b -d
  cd ..
done
sudo dpkg -i ./cuttlefish-base_*_*64.deb || sudo apt-get install -f
sudo dpkg -i ./cuttlefish-user_*_*64.deb || sudo apt-get install -f
sudo usermod -aG kvm,cvdnetwork,render $USER
sudo reboot

# 启动模拟器：
HOME=$PWD ./bin/launch_cvd


#在自己的机器上连接cuttlefish:先安装scrcpy，在Ubuntu上执行

sudo apt install -y scrcpy
# macOS上执行 
brew install scrcpy
#然后连接：
adb connect $ip_of_cf:6520
scrcpy
