[English](../README.md) | **简体中文** | [日本語](../ja/README.md) | [Türkçe](../tr/README.md)
|
||||
|
||||
一个 Android 上基于内核的 root 方案,由 [`tiann/KernelSU`](https://github.com/tiann/KernelSU) 分叉而来,添加了一些有趣的变更。
|
||||

|
||||
[](/LICENSE)
|
||||
|
||||
## 特性
|
||||
|
||||
1. 基于内核的 `su` 和权限管理。
|
||||
2. 基于 [Magic Mount](https://github.com/5ec1cff/KernelSU) 的模块系统。
|
||||
3. [App Profile](https://kernelsu.org/zh_CN/guide/app-profile.html): 把 Root 权限关进笼子里。
|
||||
4. 支持 non-GKI 与 GKI 1.0。
|
||||
5. KPM 支持
|
||||
6. 可调整管理器外观,可自定义 susfs 配置。
|
||||
|
||||
## 兼容状态
|
||||
|
||||
- KernelSU 官方支持 GKI 2.0 的设备(内核版本 5.10 以上)。
|
||||
|
||||
- 旧内核也是兼容的(最低 4.14+),不过需要自己编译内核。
|
||||
|
||||
- 通过更多的反向移植,KernelSU 可以支持 3.x 内核(3.4-3.18)。
|
||||
|
||||
- 目前支持架构 : `arm64-v8a`、`armeabi-v7a (bare)`、`X86_64`。
|
||||
|
||||

||||
|
||||
要将 SukiSU 翻译成您的语言,或完善现有的翻译,请使用 [Crowdin](https://crowdin.com/project/SukiSU-Ultra).
|
||||
|
||||
## KPM 支持
|
||||
|
||||
- 基于 KernelPatch 开发,移除了与 KernelSU 重复的功能。
|
||||
- 正在进行(WIP):通过集成附加功能来扩展 APatch 兼容性,以确保跨不同实现的兼容性。

|
||||
|
||||
> [!Note]
|
||||
>
|
||||
> 1. 需要 `CONFIG_KPM=y`
|
||||
> 2. Non-GKI 设备需要 `CONFIG_KALLSYMS=y` and `CONFIG_KALLSYMS_ALL=y`
|
||||
> 3. 对于低于 `4.19` 的内核,需要从 `4.19` 的 `set_memory.h` 进行反向移植。
|
||||
|
||||
## 故障排除
|
||||
|
||||
1. 卸载管理器后系统卡住?

卸载 _com.sony.playmemories.mobile_

# 集成指导
|
||||
|
||||
SukiSU 可以集成到 GKI 和 non-GKI 内核中,并且已反向移植到 4.14 版本。
|
||||
|
||||
<!-- 应该是 3.4 版本,但 backslashxx 的 syscall manual hook 无法在 SukiSU 中使用-->
|
||||
|
||||
有些 OEM 定制可能导致多达 50% 的内核代码超出内核树代码,而非来自上游 Linux 内核或 ACK。因此,non-GKI 内核的定制特性导致了严重的内核碎片化,而且我们缺乏构建它们的通用方法。因此,我们无法提供 non-GKI 内核的启动映像。
|
||||
|
||||
前提条件:开源的、可启动的内核。
|
||||
|
||||
## Hook 方法
|
||||
|
||||
1. **KPROBES hook:**
|
||||
|
||||
- GKI kernels 的默认 hook 方法。
|
||||
- 需要 `# CONFIG_KSU_MANUAL_HOOK is not set`(未设定) & `CONFIG_KPROBES=y`
|
||||
- 用作可加载的内核模块 (LKM).
|
||||
|
||||
2. **Manual hook:**
|
||||
|
||||
<!-- - backslashxx's syscall manual hook: https://github.com/backslashxx/KernelSU/issues/5 (v1.5 version is not available at the moment, if you want to use it, please use v1.4 version, or standard KernelSU hooks)-->
|
||||
|
||||
- 需要 `CONFIG_KSU_MANUAL_HOOK=y`
|
||||
- 需要 [`guide/how-to-integrate.md`](how-to-integrate.md)
|
||||
- 需要 [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source)
|
||||
|
||||
3. **Tracepoint Hook:**
|
||||
|
||||
- 自 SukiSU commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124) 引入的 hook 方法
|
||||
- 需要 `CONFIG_KSU_TRACEPOINT_HOOK=y`
|
||||
- 需要 [`guide/tracepoint-hook.md`](tracepoint-hook.md)
|
||||
|
||||
<!-- This part refer to [rsuntk/KernelSU](https://github.com/rsuntk/KernelSU). -->
|
||||
|
||||
如果您能够构建可启动内核,有两种方法可以将 KernelSU 集成到内核源代码中:
|
||||
|
||||
1. 使用 `kprobe` 自动集成
|
||||
2. 手动集成
|
||||
|
||||
## 与 kprobe 集成
|
||||
|
||||
适用:
|
||||
|
||||
- GKI 内核
|
||||
|
||||
不适用:
|
||||
|
||||
- non-GKI 内核
|
||||
|
||||
KernelSU 使用 kprobe 机制来做内核的相关 hook,如果 _kprobe_ 可以在你编译的内核中正常运行,那么推荐用这个方法来集成。
|
||||
|
||||
请参阅此文档 [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#integrate-with-kprobe)。虽然标题为“适用于 non-GKI”,但仅适用于 GKI。
|
||||
|
||||
替换 KernelSU 添加到内核源代码树的步骤的执行命令为:
|
||||
|
||||
```sh
|
||||
curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
|
||||
```
|
||||
|
||||
## 手动修改内核源代码
|
||||
|
||||
适用:
|
||||
|
||||
- GKI 内核
|
||||
- non-GKI 内核
|
||||
|
||||
请参考此文档 [https://github.com/~ (non-GKI 内核集成)](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source) 和 [https://github.com/~ (GKI 内核构建)](https://kernelsu.org/zh_CN/guide/how-to-build.html) 进行手动集成。虽然第一个链接的标题是“适用于 non-GKI”,但它也适用于 GKI。两者都可以正常工作。
|
||||
|
||||
还有另一种集成方法,但是仍在开发中。
|
||||
|
||||
<!-- 这是 backslashxx 的syscall manual hook,但目前无法使用。 -->
|
||||
|
||||
将 KernelSU(SukiSU)添加到内核源代码树的步骤的运行命令将被替换为:
|
||||
|
||||
### GKI 内核
|
||||
|
||||
```sh
|
||||
curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
|
||||
```
|
||||
|
||||
### non-GKI 内核
|
||||
|
||||
```sh
|
||||
curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
|
||||
```
|
||||
|
||||
### 带有 susfs 的 GKI / non-GKI 内核(实验)
|
||||
|
||||
```sh
|
||||
curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-{{branch}}
|
||||
```
|
||||
|
||||
分支:
|
||||
|
||||
- `main` (susfs-main)
|
||||
- `test` (susfs-test)
|
||||
- 版本号 (例如: susfs-1.5.7, 你需要在 [分支](https://github.com/SukiSU-Ultra/SukiSU-Ultra/branches) 里找到它)

# 安装指导
|
||||
|
||||
您可以前往 [KernelSU 文档 - 安装](https://kernelsu.org/guide/installation.html) 获取有关如何安装的参考,这里只是额外的说明。
|
||||
|
||||
## 通过加载可加载内核模块 (LKM) 进行安装
|
||||
|
||||
请参阅 [KernelSU 文档 - LKM 安装](https://kernelsu.org/guide/installation.html#lkm-installation)
|
||||
|
||||
从 **Android™**(商标,意为获得 Google 移动服务的许可)12 开始,搭载内核版本 5.10 或更高版本的设备必须搭载 GKI 内核。因此你或许可以使用 LKM 模式。
|
||||
|
||||
## 通过安装内核进行安装
|
||||
|
||||
请参阅 [KernelSU 文档 - GKI 模式安装](https://kernelsu.org/guide/installation.html#gki-mode-installation)
|
||||
|
||||
我们提供预编译的内核供您使用:
|
||||
|
||||
- [ShirkNeko 内核](https://github.com/ShirkNeko/GKI_KernelSU_SUSFS)(添加了 ZRAM 压缩算法补丁、susfs 文件和 KPM 文件。适用于很多设备。)
|
||||
- [MiRinFork 内核](https://github.com/MiRinFork/GKI_SukiSU_SUSFS)(添加了 susfs 文件和 KPM 文件。最接近 GKI 的内核,适用于大多数设备。)
|
||||
|
||||
虽然某些设备可以使用 LKM 模式安装,但无法使用 GKI 内核将其安装到设备上;因此,需要手动修改内核进行编译。例如:
|
||||
|
||||
- 欧珀(一加、真我)
|
||||
- 魅族
|
||||
|
||||
此外,我们还为您的 OnePlus 设备提供预编译的内核:
|
||||
|
||||
- [ShirkNeko/Action_OnePlus_MKSU_SUSFS](https://github.com/ShirkNeko/Action_OnePlus_MKSU_SUSFS)(添加 ZRAM 压缩算法补丁、susfs 和 KPM。)
|
||||
|
||||
使用上面的链接,Fork 到 GitHub Action,填写构建参数,进行编译,最后将 zip 文件以 AnyKernel3 后缀上传到 GitHub Action。
|
||||
|
||||
> [!Note]
|
||||
>
|
||||
> - 使用时,您只需填写版本号的前两部分,例如 `5.10`、`6.1`...
|
||||
> - 使用前请确保您了解处理器名称、内核版本等信息。

# Tracepoint Hook 集成
|
||||
|
||||
## 介绍
|
||||
|
||||
自 commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124) 起,SukiSU 引入了 Tracepoint Hook
|
||||
|
||||
该 Hook 理论上相比于 Kprobes Hook,性能开销更小,但次于 Manual Hook / Syscall Hook
|
||||
|
||||
> [!NOTE]
|
||||
> 本教程参考了 [backslashxx/KernelSU#5](https://github.com/backslashxx/KernelSU/issues/5) 的 syscall hook v1.4 版本钩子,以及原版 KernelSU 的 [Manual Hook](https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source)
