gtoad/android_inline_hook_arm64

Build an .so file to automatically do the android_native_hook work. Supports ARM64 ! With this, tools like Xposed can do android native hook.

android_inline_hook_arm64's Issues

建议把接口的参数改成 跟substrate一样

如何使用cmake编译Inline.so

在Android studio中引入了源码，采用的cmake，编译会像下面这样报错：
InlineHook/libIhook.a(Ihook.c.o): In function BuildStub': E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x3c): undefined reference to _old_function_addr_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x40): undefined reference to _old_function_addr_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x44): undefined reference to _hookstub_function_addr_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x48): undefined reference to _hookstub_function_addr_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x4c): undefined reference to _shellcode_end_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x50): undefined reference to _shellcode_end_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x54): undefined reference to _shellcode_start_s' E:/Projects/Android Projects/DuoDianY2/app/src/main/cpp/InlineHook/Ihook.c:(.text.BuildStub+0x58): undefined reference to `_shellcode_start_s' clang++: error: linker command failed with exit code 1 (use -v to see invocation) ninja: build stopped: subcommand failed.
想请教下您是因为cmake不支持shellcode吗

nice tool

print register value

Hi,I want to print register value like below.
LOGI("dlsym handle is: %s",(char*)regs->uregs[0]); LOGI("dlsym symbol is: %s",(char *)regs->uregs[1]);

But it can't work.Could you help me?

hook dlsym 怎么一直崩溃？

bool InlineHook(void *pHookAddr, void (*onCallBack)(struct user_pt_regs *))
{
    bool bRet = false;
    LOGI("InlineHook");

    if(pHookAddr == NULL || onCallBack == NULL)
    {
        return bRet;
    }

    INLINE_HOOK_INFO* pstInlineHook = malloc(sizeof(INLINE_HOOK_INFO));
    memset(pstInlineHook, 0, sizeof(INLINE_HOOK_INFO));
    pstInlineHook->pHookAddr = pHookAddr;
    pstInlineHook->onCallBack = onCallBack;

    if(HookArm(pstInlineHook) == false)
    {
        LOGI("HookArm fail.");
        free(pstInlineHook);
        return bRet;
    }
    return true;
}


void dlsym_callback(struct user_pt_regs *regs) //参数regs就是指向栈上的一个数据结构，由第二部分的mov r0, sp所传递。
{
    LOGI("In Evil Hook Stub.");
}

int main()
{
    PF_dlsym old_dlsym = (PF_dlsym)dlsym(dlopen("libdl.so", RTLD_NOW), "dlsym");
    printf("get dlsym %p\n", old_dlsym);
    InlineHook(old_dlsym, dlsym_callback);
    dlsym(dlopen("libc.so", RTLD_NOW), "read");  《---- 执行到这里 ，可以进入回调，然后会失败
    getchar();
    return 0;
}
