Enable kernel options for Docker

Add a simple option for enabling all the requirements for Docker to run.

Install

1. Create a folder inside your kernel source tree, for example utils, then place the Kconfig in there.
2. Add a line into the root Kconfig: source "utils/Kconfig".

Sample final Kconfig:

#
# For a description of the syntax of this configuration file,
# see Documentation/kbuild/kconfig-language.txt.
#
mainmenu "Linux/$ARCH $KERNELVERSION Kernel Configuration"

config SRCARCH
        string
        option env="SRCARCH"

source "utils/Kconfig"

source "arch/$SRCARCH/Kconfig"

Now enable the Docker support option:

Utilities --->
  [*] Docker support

And you should be good to go. Compile the kernel, install, reboot, enjoy.

下面的所有操作可由此 https://github.com/tomxi1997/LXC_KernelSU_Action 一键编译生成lxc kernelsu内核，手动操作的可看下面↓

11.1 #lxc配置添加到内核源码，在内核源码目录下执行

git clone https://github.com/tomxi1997/lxc-docker-support-for-android.git utils

git clone https://github.com/tomxi1997/AnyKernel3.git

11.2 #在内核源码根目录,编辑Kconfig

添加以下内容，可参考2. Add a line into the root Kconfig样式修改

source "utils/Kconfig"

22。参照utils下的补丁文件进行修改，fix_cgroup.patch，fix_panic.patch 主要修改以下这两个文件 kernel/cgroup/cgroup.c net/netfilter/xt_qtaguid.c

33。然后在内核的配置文件，按你机型的实际配置来修改。#手机的内核配置文件，一般在内核源码目录下的arch/arm64/configs或arch/arm64/configs/vendor下，一般为机型代号，高通骁龙处理器代号啥的，比如mi5 的为gemini_defconfig,一加8系列为kona_pref_defconfig,按实际情况修改。

在arch/arm64/configs/xxxx_defconfig 中加入以下内容

CONFIG_ANDROID_PARANOID_NETWORK is not set

CONFIG_DOCKER=y

44。按照一般方式重新编译内核，用AnyKernel3 打包后刷入内核，可用kernelsu action 来搞,可用这https://github.com/wu17481748/LXC-DOCKER-KernelSU_Action或实体机........

可参考我的酷安 ，但是对手机上chroot中使用的，实体电脑上也类似的，工具链选择 clang383902b +Google gcc4.9或clang-r416189+Google gcc4.9, 系统选择ubuntu20.04， 可最终效果演示 【在Android中运行LXC容器，Docker容器（需要刷入自定义内核）-哔哩哔哩】 https://b23.tv/yAR1IzO 到时我出一个在x86_64的编译教程。
