分享Win10 1903過TP的雙機調試問題

差不多我用到的大部分代碼都是從上面cv（Ctrl+c---->Ctrl+v）下來的

1、首先解決The context is partially valid. Only x86 user-mode context is available.

具體方式是hookKdpTrap

2、防止安全組件加載失敗

SharedUserData->KdDebuggerEnabled = FALSE; //防止安全組件加載失敗，SharedUserData這個是一個導出的全局變量直接寫就行

3、XP會清零KdDebuggerEnabled

這里本來是打算做一個定時器，但是還是會導致TesNginx.Sycccccccccccccc出現藍屏，所以只有手動的去修改

4、斷鏈隱藏 kdcom，防止kdcom內存被清空導致和windbg通訊不了

5、XP會檢測KdEnteredDebugger，如果是1就直接藍屏

處理方式是讓他去找其他位置(PUCHAR)KdEnteredDebugger + 0x30; //據暗中觀察，+0x30 的位置恒為0

做完這些之后基本上就能夠下斷點了，但是其實還是有問題（由于hook了系統函數有一定的幾率會觸發109錯誤->PathGuard，一開始我也分不清楚，后來慢慢的也了解了）

之后放上一張過了圖片

最后把代碼也帶上吧，.asm文件很簡單簡單的inlinhook就行了

#include Ntifs.h>
#include ntimage.h>
extern void debg();
//關閉寫保護
KIRQL WPOFFx64(){
 KIRQL irql = KeRaiseIrqlToDpcLevel();
 UINT64 cr0 = __readcr0();
 cr0 = 0xfffffffffffeffff;
 __writecr0(cr0);
 _disable();
 return irql;
}
//開啟寫保護
void WPONx64(KIRQL irql){
 UINT64 cr0 = __readcr0();
 cr0 |= 0x10000;
 _enable();
 __writecr0(cr0);
 KeLowerIrql(irql);
}
