Introduction

An addon root hiding kernel patches and userspace module for KernelSU.

The ksu_susfs userspace tool and ksu module requires a susfs patched kernel to work.

Warning

This is only experimental code, that said it can harm your system or cause performance hit, YOU ARE !! W A R N E D !! already

Compatibility

The susfs kernel patches may differ for different kernel version or even on the same kernel version, you may need to create your own patches for your kernel.

Patch Instruction

1. Clone the repo with a tag that has release version, as tag with release version is more stable
2. Run cp ./kernel_patches/KernelSU/10_enable_susfs_for_ksu.patch $KERNEL_ROOT/KernelSU/
3. Run cp ./kernel_patches/50_add_susfs_in_kernel-<kernel_version>.patch $KERNEL_ROOT/
4. Run cp ./kernel_patches/fs/susfs.c $KERNEL_ROOT/fs/
5. Run cp ./kernel_patches/include/linux/susfs.h $KERNEL_ROOT/include/linux/
6. Run cd $KERNEL_ROOT/KernelSU and then patch -p1 < 10_enable_susfs_for_ksu.patch
7. Run cd $KERNEL_ROOT and then patch -p1 < 50_add_susfs_in_kernel.patch, if there are failed patches, you may try to patch them manually by yourself.
8. Make sure again to have CONFIG_KSU and CONFIG_KSU_SUSFS enabled before building the kernel, some other SUSFS feature are disabled by default, you may turn it on via menuconfig or change it in your config file
9. Build and flash the kernel.

Build ksu_susfs userspace tool

1. Run ./build_ksu_susfs_tool.sh to build the userspace tool ksu_susfs, and the arm64 and arm binary will be copied to ksu_module_susfs/tools/ as well.
2. Now you can also push the compiled ksu_susfs tool to /data/adb/ksu/bin/ so that you can run it directly in adb root shell or termux root shell, as well as in your own ksu modules.

Build ksu module

The ksu module here is just a demo to show how to use it. It will also copy the ksu_susfs tool to /data/adb/ksu/bin/ as well when installing the module.

1. ksu_susfs tool can be run in any stage scripts, post-fs-data.sh, services.sh, boot-completed.sh according to your own need.
2. Then run ./build_ksu_module.sh to build the KernelSU module.

Usage of ksu_susfs

• Run ksu_susfs in root shell for usages.
