### 🤔 这是什么
**Xiaomi K70e (duchamp)** 一键 Root 工具，基于 **CVE-2026-43499 (IonStack)** 内核漏洞提权，集成 **KernelSU** 守护进程。
**通俗版**：你点一下，手机就 root 了。就这么简单。
**710 解锁节版**：不是 711，不是 709，是 710。这一天我们不解锁手机，我们解放手机。
**哲学版**：当你在 `/proc/` 里凝视深渊，深渊也在用 `pipe_physrw` 凝视你。

### 🧠 漏洞链
| 阶段 | 技术 | 描述 |
|------|------|------|
| 1. KASLR 泄漏 | `pselect` slide 侧信道 | 利用 nfulnl_log_packet 数据别名读 `_stext` |

| 3. 物理读写原语 | pipe_buffer ops 伪造 | 伪造 pipe_buf_ops → 获得任意内核 phys rw |
| 4. 提权 | patch cred + seccomp + selinux | 改 cred uid=0、cap 全满、关 seccomp、关 selinux |
| 5. 持久化 | 嵌入式 KernelSU | 写入并启动 ksud（KernelSU 守护进程） |

### 🎭 用户故事
**710 解锁节**
```
用户: "我的 K70e 能解锁吗？"
我: "不用解锁，直接 root。"
用户: "？？？"
我: "w 710"
用户: "什么？"
我: "710解锁节最新力作，不是解锁BL，是解放手机。"
```
**第一次开机**
```
用户: "为什么我的手机重启了？"
preload.so: "别慌，我在提权。"
用户: "KernelSU 是什么？"
preload.so: "就是你手机上现在跑的 root 管理器。"
```
**KernelSU 集成**
```
用户: "root 之后怎么管理？"
ksud: "你好，我是 KernelSU 守护进程。"
用户: "你能干什么？"
ksud: "我可以给应用授权 root。"
用户: "你不是系统自带的吧？"
ksud: "我是嵌入在 preload.so 里的。"
用户: "牛逼。"
```
**翻车现场**
```
用户: "我刷了你这个，变砖了！！！"
我: "你什么机型？"
用户: "iPhone 14。"
我: "......你认真的？"
用户: "我看你说 710 解锁节就来试试。"
我: "710 是 Xiaomi 14 的代号之一，不是 iPhone 14。你走吧。"
```

### ⚙️ 工作原理
1. **加载 preload.so** — 注入任意应用（`LD_PRELOAD`），触发 `__attribute__((constructor))`
2. **泄漏 KASLR 基址** — 通过 `pselect` 侧信道 + nfulnl_log_packet 数据别名读取 `_stext`
3. **劫持 FOPS 表** — 利用 futex PI 竞争条件 + pipe 操作改写文件操作的 ops 指针
4. **获得 phys rw** — 伪造 `pipe_buf_ops`，实现任意内核物理地址读写
5. **修补 cred** — 找到 root child 进程的 cred，改 uid=0、cap 全满、sid=kernel
6. **关安全机制** — 关 seccomp、清 TIF_SECCOMP、写 selinux enforce=0
7. **启动 KernelSU** — 提取嵌入的 ksud 到 `/data/local/tmp/ksud`，启动 KernelSU 守护进程

### 📦 使用方式
#### 前置条件
- Xiaomi K70e (duchamp) 或其它支持的设备
- 已解锁 Bootloader（或不解锁的临时 root 也支持）
- ADB 调试已开启
- 一个不怕变砖的勇气
#### 快速开始
```bash
# 从 Release 下载 preload.so
wget https://github.com/Colorful-glassblock/duchamp-root/releases/download/v1.0/preload.so
# 推送到设备
adb push preload.so /data/local/tmp/
# 通过 LD_PRELOAD 注入任意应用触发
adb shell
su -c "LD_PRELOAD=/data/local/tmp/preload.so your_app"
```
或者使用我们提供的注入脚本（TODO）。
#### 自行编译
```bash
# 需要 NDK 或 Termux 的 aarch64-linux-android-clang
make PROJECT=duchamp
# 输出在 build/duchamp/bin/preload.so
```

### 🛡️ 免责声明
```
本工具仅供学习研究使用。
解锁 Bootloader 可能导致保修失效。
Root 设备可能导致变砖、数据丢失、银行 App 无法使用。
如果你因此被女朋友甩了，那是你自己的问题。
如果你刷了变砖来找我，我会笑你。
710解锁节快乐！🚀

### 💡 彩蛋 / FAQ
**Q: 为什么叫 710 解锁节？**
A: 7 月 10 日。不是 711（便利店），不是 709（不知道什么东西）。是 710。这一天我们不解锁 BL，我们解放手机。
**Q: 710 和 Xiaomi 14 有什么关系？**
A: Xiaomi 14 的代号之一是 `frankel` 开头的设备，不是 `shennong`。等等，710 是节日不是代号...
**Q: QwQ?**
A: 情绪稳定（假的）。
**Q: 有 su 吗？**
A: 没有，只有 KernelSU。需要 su 的话装个 KernelSU 管理器自己开。
**Q: 支持其它机型吗？**
A: 看 `src/targets/` 目录。你的机型在里面就支持，不在就自己加。
**Q: 我能在没有解锁 BL 的情况下用吗？**
A: 可以，`LD_PRELOAD` 注入不需要解锁 BL。但是重启后需要重新注入。
**Q: 会触发 Kernelsnitch 吗？**
A: 已经内置了 Kernelsnitch 绕过，但如果你被检测到了，那是 skill issue。
**Q: 114514?**
A: はいはいわかりました草

### 🤔 What is This
**Xiaomi K70e (duchamp)** one-click root tool based on **CVE-2026-43499 (IonStack)** kernel exploit, integrated with **KernelSU** daemon.
**Casual version**: Click, root, done.
**710 Festival version**: July 10th. Not July 11th (convenience store), not July 9th (who cares). July 10th. On this day we don't unlock bootloaders, we liberate phones.
**Philosophical version**: When you stare into `/proc/`, `/proc/` stares back at you with `pipe_physrw`.

### 🎯 Supported Devices
| Device | Codename | SoC | Kernel | Status |
|--------|----------|-----|--------|:------:|
| Redmi K70E | **duchamp** | MT6897 (Dimensity 8300) | 6.1.138-android14-11 | ✅ |
> Other devices under `src/targets/` are reference configs from the original project, not verified.

### 🧠 Exploit Chain
| Stage | Technique | Description |
|-------|-----------|-------------|
| 1. KASLR leak | `pselect` slide side-channel | Read `_stext` via nfulnl_log_packet data alias |
| 2. FOPS hijack | `pselect` arbitrary stack write | FUTEX_CMP_REQUEUE_PI race → overwrite ops table |
| 3. Phys rw primitive | Forged `pipe_buf_ops` | Fake pipe buffer ops → arbitrary kernel physical rw |
| 4. Escalation | Patch cred + seccomp + selinux | uid=0, full caps, disable seccomp, disable selinux |
| 5. Persistence | Embedded KernelSU | Write and launch ksud (KernelSU daemon) |

### ⚙️ How It Works
1. **Load preload.so** — inject via `LD_PRELOAD` into any app, triggers `__attribute__((constructor))`
2. **Leak KASLR base** — `pselect` side-channel via nfulnl_log_packet data alias reads `_stext`
3. **Hijack FOPS table** — futex PI race condition + pipe ops rewrite
4. **Get phys rw** — forge `pipe_buf_ops` for arbitrary kernel physical memory access
5. **Patch cred** — find root child task, patch uid=0, full caps, kernel sid
6. **Disable security** — patch seccomp, clear TIF_SECCOMP, selinux enforce=0
7. **Launch KernelSU** — extract embedded ksud to `/data/local/tmp/ksud`, start KernelSU daemon
---
### 📦 Usage
#### Prerequisites
- Xiaomi K70e (duchamp) or other supported device
- Unlocked bootloader (or not — LD_PRELOAD works either way)

#### Quick Start
```bash
# Download preload.so from Releases
wget https://github.com/Colorful-glassblock/duchamp-root/releases/download/v1.0/preload.so

adb push preload.so /data/local/tmp/
# Inject into any app via LD_PRELOAD
adb shell
LD_PRELOAD=/data/local/tmp/preload.so your_app
```
#### Build from Source
```bash
# Requires NDK or Termux aarch64-linux-android-clang
make PROJECT=duchamp
# Output at build/duchamp/bin/preload.so
```

### 🛡️ Disclaimer
```
This tool is for educational purposes only.
Unlocking BL may void warranty.
Rooting may cause bootloop, data loss, or app incompatibility.
If you brick your device, that's a skill issue.
If you blame me, that's a you problem.
If you laugh, you're one of us.
710 Unlock Festival! 🚀

### 💡 Trivia / FAQ
**Q: Why "710 Unlock Festival"?**
A: July 10th. Not convenience store day (7/11), not whatever July 9th is. July 10th. On this day we don't unlock bootloaders, we liberate phones.
**Q: QwQ?**
A: Emotionally stable (big lie).
**Q: Can I use this without unlocking BL?**
A: Yes. `LD_PRELOAD` injection doesn't need an unlocked BL. But you'll need to re-inject after reboot.
**Q: Will this trigger Kernelsnitch?**
A: Kernelsnitch bypass is included. If you still get caught, skill issue.
**Q: 114514?**
A: はいはいわかりました草
