构建调试Linux内核网络代码的环境MenuOS系统

下载内核

xz -d linux-5.0.1.tar.xz
tar -xvf linux-5.0.1.tar
cd linux-5.0.1

下载编译工具

sudo apt install build-essential flex bison libssl-dev libelf-dev libncurses-dev

配置编译内核

make i386_defconfig

升级当前系统内核

sudo make modules_install 
sudo make install
sudo update-grub
reboot
uname -a

通过QEMU虚拟机加载内核

sudo apt install qemu
qemu-system-i386 -kernel linux-5.0.1/arch/x86/boot/bzImage #make i386_defconfig
qemu-system-x86_64 -kernel linux-5.0.1/arch/x86_64/boot/bzImage

构造MenuOS

git clone https://github.com/mengning/menu.git
cd menu
sudo apt-get install libc6-dev-i386
make rootfs
cd ..
qemu-system-i386 -kernel linux-5.0.1/arch/x86/boot/bzImage -initrd rootfs.img #makei386_defconfig
qemu-system-x86_64 -kernel linux-5.0.1/arch/x86_64/boot/bzImage -initrd

启动gdb server

qemu -kernel ../linux-5.0.1/arch/x86/boot/bzImage -initrd ../rootfs.img -append  nokaslr -s -S

建立gdb与gdb server连接

gdb
file ~/linux-5.0.1/vmlinux
target remote:1234
break start_kernel
c
