 # Magisk
 
-## How to build Magisk
+## Building Environment Requirements
 
-#### Building has been tested on 3 major platforms:
+1. Python 3.5+: run `build.py` script
+2. Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
+3. Latest Android SDK: set `ANDROID_HOME` environment variable to the path to Android SDK
+4. Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or optionally specify a custom path `ANDROID_NDK`
+5. (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
 
-***macOS 10.12.5***  
-***Ubuntu 17.04 x64***  
-***Windows 10 Creators Update x64***  
-
-#### Environment Requirements
-
-1. Python 3 **(>= 3.5)**: `python3` (or in some cases `python`) should be accessible  
-2. Java runtime: `java` should be accessible  
-3. (Unix only) C compiler: `gcc` should be accessible  
-4. Android SDK: `ANDROID_HOME` environment variable should point to the Android SDK folder  
-5. NDK: Install NDK using `sdkmanager`, or through Android SDK Manager  
-6. Android build-tools: Should have build-tools version matching `MagiskManager/app/build.gradle` installed  
-
-#### Instructions and Notes
-
-1. The python build script uses ANSI color codes to change the color of the terminal output. For Windows, this **only** works on Windows 10, as previous Windows console do not support them. If you insist to use an older Windows version, a quick Google search should provide many workarounds  
-2. After installing the latest Python 3 on Windows (allow the installer to add Python to PATH, or you'll have to manually set the environment), instead of calling `python3` like most Unix environment, you should call `python` in shell (cmd or Powershell both OK). You can double check the version by `python --version`  
-3. The build script will do several checks, it will refuse to run if the environment doesn't meet the requirements  
-4. For further instructions, please check the built in help message by `python3 build.py -h`  
-(Unix users can simply `./build.py -h`, Windows users, as mentioned, call `python` instead)  
-5. Each action has its own help message, access them by commands like `python3 build.py all -h`  
-6. To build Magisk for release (enabled through the `--release` flag, the script builds in debug mode by default), you will need to provide a Java keystore file, and place it in `release_signature.jks` to sign Magisk Manager APK for release builds. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually)
-7. To properly setup the Android SDK environment, the easiest way is to use Android Studio and open Magisk Manager. If gradle sync passed, your build-tools etc. should be set properly. You can also access SDK Manager GUI within Android Studio to download NDK. Don't forget to add Android Studio's SDK path into environment variable ANDROID_HOME.  
+## Building Notes and Instructions
+1. Building is tested on macOS, Ubuntu, and Windows 10 using the latest stable NDK and NDK r10e. Officially released binaries were built with NDK r10e.
+2. Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+3. Run `build.py` with argument `-h` to see the built-in help message. The `-h` option also works for each supported actions, e.g. `./build.py binary -h`
+4. By default, `build.py` build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the `--release` flag), you need a Java Keystore file `release-key.jks` to sign Magisk Manager's APK. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually).
+5. The SafetyNet extension pack requires the full Magisk Manager as a `compileOnly` dependency. Build the **release** APK, convert it back to Java `.class` files (I use [dex2jar](https://github.com/pxb1988/dex2jar)), and place the converted JAR under `snet/libs` before compiling.

+## Introduction
+Magisk is a suite of open source tools for devices running Android version higher than 5.0 Lollipop (API 21). It establishes an environment which covers most stuffs you need for Android customization, such as root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt patches etc..
+
+Furthermore, Magisk provides a **Systemless Interface** to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact, all of which accomplished by only patching the boot image. With its systemless nature along with several other hacks, Magisk can hide modifications from nearly any existing system integrity verifications, one of the main target is to hide from [Google's SafetyNet API](https://developer.android.com/training/safetynet/index.html).

+## Boot Stages
+If you are working on complicated projects, you shall need more control to the whole process. Magisk can run scripts in different boot stages, so you can fine tune exactly what you want to do. It's recommended to read this documentation along with the procedure graph.
+
+- post-fs mode
+    - **This stage is BLOCKING. Boot process will NOT continue until everything is done, or 10 seconds has passed**
+    - Happens after most partitions are mounted. `/data` might not be available since `vold` is not started yet
+    - Magisk will bind mount files under `/cache/magisk_mount/system` and `/cache/magisk_mount/vendor`
+    - It is only **Simple Mount**, which means it will replace existing files, but cannot add/remove files.
+    - This part is mostly deprecated (reasons in details)
+- post-fs-data mode
+    - **This stage is BLOCKING. Boot process will NOT continue until everything is done, or 10 seconds has passed**
+    - Happens after `/data` is ready (including the case when `/data` is encrypted)
+    - Happens before Zygote and system servers are started (which means pretty much everything)
+    - `/data/adb/magisk.img` will be merged, trimmed, and mounted to `MOUNTPOINT=/sbin/.core/img`
+    - Magisk will run scripts under `$MOUNTPOINT/.core/post-fs-data.d`
+    - Magisk will run scripts: `$MOUNTPOINT/$MODID/post-fs-data.sh` (placed in each module directory)
+    - Magisk will finally **Magisk Mount** module files
+- late_start service mode
+    - **This stage is NON-BLOCKING, it will run in parallel with other processes**
+    - Happens when class late_start is triggered
+    - The daemon will wait for the full `sepolicy` patch before running this stage, so SELinux is guaranteed to be fully patched
+    - Put time consuming scripts here. Boot process will get stuck if it took too long to finish your tasks in `post-fs-data`
+    - **It is recommended to run all scripts in this stage**, unless your scripts requires doing stuffs before Zygote is started
+    - Magisk will run scripts under `$MOUNTPOINT/.core/service.d`
+    - Magisk will run scripts: `$MOUNTPOINT/$MODID/service.sh` (placed in each module directory)
+
+## Magic Mount Details
+### Terminology
+- **Item**: A folder, file, or symbolic link
+- **Leaf**: An item that is on the very end of a directory structure tree. It can be either a file or symbolic link
+- **`$MODPATH`**: A variable to represent the path of a module folder
+- **Source item**: An item under `$MODPATH/system`, for example, `$MODPATH/system/bin/app_process32` is a source item
+- **Existing item**: An item in the actual filesystem, for example, `/system/bin/app_process32` is an existing item
+- **Target item**: The corresponding item of a source item. For example, the target item of `$MODPATH/system/bin/app_process32` is `/system/bin/app_process32`
+
+Note: A target item **does not** imply it is an existing item. A target item might not exist in the actual filesystem
+
+### Policies
+- For a source leaf: if its target item is also an existing item, the existing item will be replaced with the source leaf
+- For a source leaf: if its target item is not an existing item, the source leaf will be added to the path of its target item
+- For any existing item that's not a target item, it will stay intact
+
+Above is the rule of thumb. Basically it means that Magic Mount merges the two folders, `$MODPATH/system` into `/system`. A simpler way to understand is to think as the items is dirty copied from `$MODPATH/system` into `/system`.
+
+However, an addition rule will override the above policies:
+
+- For a source folder containing the file `.replace`, the source folder will be treated as if it is a leaf. That is, the items within the target folder will be completely discarded, and the target folder will be replaced with the source folder.
+
+Directories containing a file named `.replace` will **NOT** be merged, instead it directly replaces the target directory. A simpler way to understand is to think as if it wipes the target folder, and then copies the whole folder to the target path.
+
+### Notes
+- If you want to replace files in `/vendor`, please place it under `$MODPATH/system/vendor`. Magisk will handle both cases, whether the vendor partition is separated or not under-the-hood, developers don't need to bother.
+- Sometimes, completely replacing a folder is inevitable. For example you want to replace `/system/priv-app/SystemUI` in your stock rom. In stock roms, system apps usually comes with pre-optimized files. If your replacement `SystemUI.apk` is deodexed (which is most likely the case), you would want to replace the whole `/system/priv-app/SystemUI` to make sure the folder only contains the modified `SystemUI.apk` without the pre-optimized files.
+- If you are using the [Magisk Module Template](https://github.com/topjohnwu/magisk-module-template), you can create a list of folders you want to replace in the file `config.sh`. The installation scripts will handle the creation of `.replace` files into the listed folders for you.
+
+## Simple Mount Details
+(Note: this part is mostly deprecated, since starting with devices using A/B partitions, there is no longer a dedicated partition for cache because OTAs are applied live at boot. Instead, `/cache` now points to `/data/cache`, which means `post-fs` mode does not have access to `/cache` anymore)
+
+Some files require to be mounted much earlier in the boot process, currently known are bootanimation and some libs (most users won't change them). You can simply place your modified files into the corresponding path under `/cache/magisk_mount`. For example, you want to replace `/system/media/bootanimation.zip`, copy your new boot animation zip to `/cache/magisk_mount/system/media/bootanimation.zip`, and Magisk will mount your files in the next reboot. Magisk will **clone all the attributes from the target file**, which includes selinux context, permission mode, owner, group. This means you don't need to worry about the metadata for files placed under `/cache/magisk_mount`: just copy the file to the correct place, reboot then you're done!

+## Magisk Module Format
+A Magisk module is a folder placed in the root folder in `magisk.img`, which has a structure as described below:
+
+```
+$MOUNTPOINT
+├── .
+├── .
+├── $MODID                  <--- The ID of the module, should match with module.prop
+│   ├── auto_mount          <--- If this file exists, auto mount is enabled
+│   ├── disable             <--- If this file exists, the module is disabled
+│   ├── module.prop         <--- This files stores the identity and properties of the module
+│   ├── post-fs-data.sh     <--- This script will be executed in post-fs-data
+│   ├── remove              <--- If this file exists, the module will be removed next reboot
+│   ├── service.sh          <--- This script will be executed in late_start service
+│   ├── system.prop         <--- This file will be loaded as system props

+You are not required to use my Magisk Module Template to create a module. As long as you place files with the structure above, it will be recognized as a module.
+
+## Magisk Module Template
+The **Magisk Module Template** is hosted **[here](https://github.com/topjohnwu/magisk-module-template)**.
+
+It is a template to create a flashable zip to install Magisk Modules. It is designed to be simple to use so that anyone can create their own modules easily. The template itself contains minimal scripting for installation; most of the functions are located externally in [util_functions.sh](https://github.com/topjohnwu/Magisk/blob/master/scripts/util_functions.sh), which will be installed along with Magisk, and can be upgraded through a Magisk upgrade without the need of a template update.
+
+Here are some files you would want to know:
+
+- `config.sh`: A simple script used as a configuration file. It is the place to configure which features your module needs/disables. A detailed instructions on how to use the template is also written in this file.
+- `module.prop`: This file contains your module's indentity and properties, including name and versions etc.. This file will be used to identify your module on an actual device and in the [Magisk Modules Repo](https://github.com/Magisk-Modules-Repo)
+- `common/*`: Boot stage scripts and `system.prop`
+- `META-INF/com/google/android/update-binary`: The actual installation script. Modify this file for advanced custom behavior
+
+And here are some notes to be aware of:
+
+- The template depends on external Magisk scripts, please specify the correct `minMagisk` value in `module.prop` with the template version your module is based on, or the minimum Magisk version your module is tested on.
+- **Windows users please check here!!** The line endings of all text files should be in the **Unix format**. Please use advanced text editors like Sublime, Atom, Notepad++ etc. to edit **ALL** text files, **NEVER** use Windows Notepad.
+- In `module.prop`, `version` can be an arbitrary string, so any fancy version name (e.g. `ultra-beta-v1.1.1.1`) is allowed. However, `versionCode` **MUST** be an integer. The value is used for version comparison.
+- Make sure your module ID **does not contain any spaces**.

+# Tips and Tricks
+
+## OTA Installation Tips
+Magisk does modifications systemless-ly, which means applying official OTAs is much simpler. Here I provide a few tutorials for several different kind of devices to apply OTAs and preserve Magisk after the installation if possible.
+
+**This tutorial is only for Magisk v14.1+**
+
+**NOTE: In order to apply OTAs, you HAVE to make sure you haven't modified `/system` (and `/vendor` if available) in any way. Even remounting the partition to rw will tamper block verification!!**
+
+#### Prerequisites
+1. Please disable *Automatic system updates* in developer options, so it won't install OTAs without your acknowledgement.  
+    <img src="images/disable_auto_ota.png" width="250">
+1. When an OTA is available, please go to Magisk Manager → Uninstall → Restore Images. **Do not reboot immediately or you will have Magisk uninstalled.** This will restore your boot (or dtbo if available) back to 100% untouched stock images in order to pass verifications. **This step is required before doing any of the following steps written below!**  
+    <img src="images/restore_img.png" width="250">
+
+#### Devices with A/B Partitions
+(Includes Pixel family)
+
+Due to the fact that these devices have two separate partitions, and the OTA installation happens live while the system is still running, these devices have the best support: the out-of-the-box OTA installation works seamlessly and Magisk will be preserved after the installation.
+
+1. After restoring stock boot image, apply OTAs as you normally would (Settings → System → System Updates).
+1. Once the installation has passed step 1 and is starting step 2, go to Magisk Manager → Install → Install to Second Slot. This will install Magisk into the second boot image slot, which is the updated slot.  
+    <img src="images/ota_step2.png" width="250"> <img src="images/install_second_slot.png" width="250">
+1. Let the OTA finish its job. After a reboot, the bootloader will switch to the updated system. Magisk should still be installed since we already patched the new boot image.
+
+#### Devices with FlashFire Support
+(Includes Pixel family, Nexus family, Samsung devices)  
+(If you are using a device with A/B partitions, I **strongly** recommend you to use the method stated above since it uses the stock OTA installation mechanism and will always work under any circumstances)
+
+The [FlashFire](https://play.google.com/store/apps/details?id=eu.chainfire.flash) app developed by Chainfire is a great app to apply OTAs and preserve root at the same time. However, whether it supports your device/system combination depends on the application itself, and support may change in the future. If you face any issues, please directly [report to Chainfire](https://forum.xda-developers.com/general/paid-software/flashfire-t3075433).  
+
+1. After restoring the stock boot image, download the OTA (Settings → System → System Updates), **do not press reboot to install.**
+1. Open FlashFire, it should detect your OTA zip. Select OK in the popup dialog to let it do its setup.
+1. Please use the options shown in the screenshot below. The key point is to disable EverRoot (or it will install SuperSU), and add a new action to flash Magisk zip **after** the OTA update.zip (the update.zip is auto generated in the previous step).  
+    <img src="images/flashfire.png" width="250">
+1. Press the big **Flash** button, after a few minutes it should reboot updated with Magisk installed.
+
+#### Other Devices - General Case
+Unfortunately, there are no real good ways to apply OTAs on all devices. Also, the tutorial provided below will not preserve Magisk - you will have to manually re-root your device after the upgrade, and this will require PC access. Here I share my personal experience with HTC U11.
+
+1. To properly install OTAs, you should have your stock recovery installed on your device. If you have custom recovery installed, you can restore it from your previous backup, or dumps found online, or factory images provided by OEMs.  
+If you decide to start by installing Magisk without touching your recovery partition, you have a few choices, either way you will end up with a Magisk rooted device, but recovery remains stock untouched:
+    - If supported, use `fastboot boot <recovery_img>` to boot the custom recovery and install Magisk. 
+    - If you have a copy of your stock boot image dump, install Magisk by patching boot image via Magisk Manager, and manually flash it through download mode / fastboot mode / Odin
+1. Once your device has stock recovery and stock boot image restored, download the OTA. Optionally, once you have downloaded the OTA update zip, you can find a way to copy the zip out, since you are still rooted. Personally, I extract the stock boot image and recovery image from the OTA zip for future usage (to patch via Magisk Manager or restore stock recovery etc.)
+1. Apply and reboot your device. This will use the official stock OTA installation mechanism of your device to upgrade your system.
+1. Once it's done you will be left with an upgraded, 100% stock, un-rooted device. You will have to manually flash Magisk back. Consider using the methods stated in step 1. to flash Magisk without touching the recovery partition if you want to receive stock OTAs frequently.
+
+## Remove Files
+How to remove a file systemless-ly? To actually make the file **disappear** is complicated (possible, not worth the effort). **Replacing it with a dummy file should be good enough**! Create an empty file with the same name and place it in the same path within a module, it shall replace your target file with a dummy file.
+
+## Remove Folders
+Same as mentioned above, actually making the folder **disappear** is not worth the effort. **Replacing it with an empty folder should be good enough**! A handy trick for module developers using [Magisk Module Template](https://github.com/topjohnwu/magisk-module-template) is to add the folder you want to remove into the `REPLACE` list within `config.sh`. If your module doesn't provide a corresponding folder, it will create an empty folder, and automatically add `.replace` into the empty folder so the dummy folder will properly replace the one in `/system`.

+### magiskboot
+A tool to unpack / repack boot images, parse and patch cpio and dtbs, hex patch binaries, compress / decompress with multiple algorithms. It is used to install Magisk into boot images.
+
+`magiskboot` natively supports (which means it does not call external tools) all popular compression methods including `gzip` (used everywhere for compressing kernel and ramdisk), `lz4` (used to compress kernel in modern devices like Pixel), `lz4_legacy` (legacy LZ4 block format with special metadata used [only on LG](https://events.static.linuxfound.org/sites/events/files/lcjpcojp13_klee.pdf) to compress kernel), `lzma` (LZMA1 algorithm natively supported in Linux kernel, used in some custom kernel to compress ramdisk), `xz` (LZMA2 algorithm, very high compression rate, used in Magisk for high compression mode and storing binaries), and `bzip2` (used in desktop Linux boot images to create bzImage, haven't seen on Android yet).
+
+The concept of `magiskboot` is to keep the images as intact as possible. For unpacking, it extracts the large chunks of data (kernel, ramdisk, second, dtb, extra etc.) and decompress them if possible. When repacking a boot image, the original boot image has to be provided so it can use the original headers (including MTK specific headers) with only changing the necessary entries such as the data chunk sizes, and re-compress all data with the original compression method. The same concept also applies to CPIO patching: it does not extract all files, modify in file system, archive all files back to cpio as usually done to create Linux `initramfs`, instead we do modifications directly in the cpio level in memory without involving any data extraction.

+
+### magiskinit
+This tool is created to unify Magisk support for both legacy "normal" devices and new `skip_initramfs` devices. The compiled binary will replace `init` in the ramdisk, so things could be done even before `init` is started.
+
+`magiskinit` is responsible for constructing a proper rootfs on devices which the actual rootfs is placed in the system partition instead of ramdisk in `boot.img`, such as the Pixel familiy and most Treble enabled devices, or I like to call it `skip_initramfs` devices: it will parse kernel cmdline, mount sysfs, parse through uevent files to make the system (or vendor if available) block device node, then copy rootfs files from system. For normal "traditional" devices, it will simply swap `init` back to the original one and continue on to the next stage.
+
+With a proper rootfs, `magiskinit` goes on and does all pre-init operations to setup a Magisk environment. It patches rootfs on the fly, providing fundamental support such as patching `init`, `init.rc`, run preliminary `sepolicy` patches, and extracts `magisk` and `init.magisk.rc` (these two files are embedded into `magiskinit`). Once all is done, it will spawn another process (`magiskinit_daemon`) to asynchronously run a full `sepolicy` patch, then starts monitoring the main Magisk daemon to make sure it is always running (a.k.a invincible mode); at the same time, it will execute the original `init` to hand the boot process back.
+
+### magiskpolicy
+(This tool is aliased to `supolicy` for compatibility with SuperSU's sepolicy tool)
+
+This tool is an applet of `magiskinit`: once `magiskinit` had finished its mission in the pre-init stage, it will preserve an entry point for `magiskpolicy`. This tool could be used for advanced developers messing with `sepolicy`, a compiled binary containing SELinux rules. Normally Linux server admins directly modifies the SELinux policy sources (`*.te`) and recompile the `sepolicy` binary, but here we directly patch the binary file since we don't have access to the sources.
+
+All processes spawned from the Magisk daemon, including root shells and all its forks, are running in the context `u:r:su:s0`. Magisk splits the built in patches into 2 parts: preliminary and full
+
+- The preliminary patch should allow all Magisk internal procedures to run properly (can be done manually by the `--magisk` option). It also contains quite a few additional patches so most scripts can run in the daemon before the full patch is done
+- The full patch adds the rule `allow su * * *` on top of the preliminary rules. This is done because stock Samsung ROMs do not support permissive; adding this rule makes the domain effectively permissive. Due to the concern of greatly increasing the boot time, the Magisk daemon will not wait for this patch to finish until the boot stage `late_start` triggers. What this means is that **only `late_start` service mode is guaranteed to run in a fully patched environment**. For non-Samsung devices it doesn't matter because `u:r:su:s0` is permissive anyways, but for full compatibility, it is **highly recommended to run boot scripts in `late_start` service mode**.

+
+### resetprop
+An applet of `magisk`, an advanced system property manipulation utility. Here's some background knowledge: 
+
+System properties are stored in a hybrid trie/binary tree data structure in memory. These properties are allowed to be read by many processes (natively via `libcutils`, in shells via the `getprop` command); however, only the `init` process have direct write access to the memory of property data. `init` provides a `property_service` to accept property update requests and acts as a gatekeeper, doing things such as preventing **read-only** props to be overridden and storing **persist** props to non-volatile storages. In addition, property triggers registered in `*.rc` scripts are also handled here.
+
+`resetprop` is created by pulling out the portion of source code managing properties from AOSP and try to mimic what `init` is doing. With some hackery the result is that we have direct access to the data structure, bypassing the need to go through `property_service` to gain arbitrary control. Here is a small implementation detail: the data structure and the stack-like memory allocation method does not support removing props (they are **designed NOT** to be removed); prop deletion is accomplished by detaching the target node from the tree structure, making it effectively invisible. As we cannot reclaim the memory allocated to store the property, this wastes a few bytes of memory but it shouldn't be a big deal unless you are adding and deleting hundreds of thousands of props over and over again.
+
+Due to the fact that we bypassed `property_service`, there are a few things developer should to be aware of:
+
+- `on property:foo=bar` triggers registered in `*.rc` scripts will not be triggered when props are changed. This could be a good thing or a bad thing, depending on what behavior you expect. The default behavior of `resetprop` matches the original `setprop`, which **WILL** trigger events (implemented by deleting the prop and set the props via `property_service`), but there is a flag (`-n`) to disable it if you need this special behavior.
+- persist props are stored both in memory and in `/data/property`. By default, deleting props will **NOT** remove it from persistent storage, meaning the prop will be restored after the next reboot; reading props will **NOT** read from persistent storage, as this is the behavior of normal `getprop`. With the flag `-p` enabled, deleting props will remove the prop **BOTH** in memory and `/data/property`; props will be read from **BOTH** in memory and persistent storage.
+
+Command help message:
+
+```
+Usage: resetprop [flags] [options...]
+
+Options:
+   -h, --help        show this message
+   (no arguments)    print all properties

+/* magiskinit.c - Pre-init Magisk support

+ * To unify Magisk support for both legacy "normal" devices and new skip_initramfs devices,
+ * magisk binary compilation is split into two parts - first part only compiles "magisk".
+ * The python build script will load the magisk main binary and compress with lzma2, dumping
+ * the results into "dump.h". The "magisk" binary is embedded into this binary, and will
+ * get extracted to the overlay folder along with init.magisk.rc.
+ *
+ * This tool does all pre-init operations to setup a Magisk environment, which pathces rootfs
+ * on the fly, providing fundamental support such as init, init.rc, and sepolicy patching.
+ *
+ * Magiskinit is also responsible for constructing a proper rootfs on skip_initramfs devices.
+ * On skip_initramfs devices, it will parse kernel cmdline, mount sysfs, parse through
+ * uevent files to make the system (or vendor if available) block device node, then copy
+ * rootfs files from system.
+ *
+ * This tool will be replaced with the real init to continue the boot process, but hardlinks are
+ * preserved as it also provides CLI for sepolicy patching (magiskpolicy)
