分享Win10 1903过TP的双机调试问题

本文给大家分享的是Win10 1903过TP的双机调试问题，通过实例代码截图的形式给大家展示的非常详细，需要的朋友参考下
差不多我用到的大部分代码都是从上面cv（Ctrl+c---->Ctrl+v）下来的
1、首先解决The context is partially valid. Only x86 user-mode context is available.
具体方式是hookKdpTrap
2、 防止安全组件加载失败
SharedUserData->KdDebuggerEnabled = FALSE; //防止安全组件加载失败，SharedUserData这个是一个导出的全局变量直接写就行
3、XP会清零KdDebuggerEnabled
这里本来是打算做一个定时器，但是还是会导致TesNginx.Sycccccccccccccc出现蓝屏，所以只有手动的去修改
4、断链隐藏 kdcom，防止kdcom内存被清空导致和windbg通讯不了
5、XP会检测KdEnteredDebugger，如果是1就直接蓝屏
处理方式是让他去找其他位置(PUCHAR)KdEnteredDebugger + 0x30; //据暗中观察，+0x30 的位置恒为0
做完这些之后基本上就能够下断点了，但是其实还是有问题（由于hook了系统函数有一定的几率会触发109错误->PathGuard，一开始我也分不清楚，后来慢慢的也了解了）
之后放上一张过了图片
最后把代码也带上吧，.asm文件很简单简单的inlinhook就行了
#include <Ntifs.h>
#include <ntimage.h>
extern void debg();
//关闭写保护
KIRQL WPOFFx64(){
KIRQL irql = KeRaiseIrqlToDpcLevel();
UINT64 cr0 = __readcr0();
cr0 &= 0xfffffffffffeffff;
__writecr0(cr0);
_disable();
return irql;
}
//开启写保护
void WPONx64(KIRQL irql){
UINT64 cr0 = __readcr0();
cr0 |= 0x10000;
_enable();
__writecr0(cr0);
KeLowerIrql(irql);
}
