YPatch

Patching and hooking the Linux kernel with only stripped Linux kernel image.

• Obtain all symbol information without source code and symbol information.
• Inject arbitrary code into the kernel. (Static patching the kernel image or Runtime dynamic loading).
• Kernel function inline hook and syscall table hook are provided.
• Additional SU for Android.

If you are using Android, YAPatch would be a better choice.
