GlossHook

A simple Android arm Hook library.

English

Features:

Support for Android Thumb/ARM/ARM64 architectures.
Implementation of Inline Hook and GotHook (not PLT Hook).
Support for hooking a single branch instruction (B, BL, BLX) calling a function. Sometimes you may only need to hook one specific call site of a function, rather than all call sites.
Support for hooking short functions (minimum 4 bytes).
Support for hook patching at any address within executable code. You can read and write registers, stack, and call other functions within your hooked function.
After hooking, you can choose to either callback the original function or directly replace the function.
Support for multiple hooks at the same location.
For multiple hooks at the same location, you can enable/disable/remove any individual hook or all hooks using the hook pointer or hook address. Enabling/disabling/removing one hook does not affect other hooks at the same location.
If multiple users use GlossHook to hook the same location, any user can enable/disable/remove other hooks using the hook pointer.
Provides a function to get the number of hooks at a specific location.
Support for replacing a user function that is already being hooked.
Provides common API functions for library lookup, library information, symbol address retrieval, memory read/write, and memory permission removal, etc.

一个简易、功能多的安卓arm hook库. GlossHook目前只是一个arm的分支版本，待以后更新(目前兼容性不敢保证)，但基本上可以使用.

支持thumb/arm/arm64的InlineHook和GotHook(不是PLT Hook).
支持对单个分支指令(B BL BLX)调用函数的hook，有时候你可能只需要hook其中一处调用点，而不是函数的全部调用点.
支持短函数Hook(最短4字节函数).
支持对函数代码内任意位置地址的hook patch，在用户函数中可读写hook位置的寄存器、栈、调用任何类型的函数.
hook后，可回调原函数，也可不回调直接替换函数.
支持对同一个位置的多次hook.
同一个位置有多个hook时，支持通过hook指针和hook位置，开启/关闭/删除任意一个或全部的hook. 开启/关闭/删除任意1个hook时，对同位置其它hook不影响.
如果多个使用方使用GlossHook对同一个位置hook，任意一个使用方可以通过地址开启/关闭/删除其它的hook.
提供了函数获取一个位置被hook的数量.
支持替换已经正在hook的用户函数
提供常用的库查找、库信息、获取符号地址、读写内存、解除内存权限等API函数.
其它待更新ing
