显示每个CPU的IDT信息

0x00 简介

记得2008年看保护模式的教程时，痛苦与那些众多的位信息等复杂的结构。 后来入这行，干了几年的驱动。 这是才对这些CPU基本的知识有点了解。

IDT，中断描述符表，这个基本的东西，岂能不会。 IDT HOOK的东西已经很多了，不过这里不是搞这个的(因为64位windows上是不建议的，除非...)，而是检测IDT HOOK，向处理器虚拟化进军的。

好了，闲话不说，进入正题，之前之所以没有搞是因为没有找到权威的，可行的资料，具体的说是结构。

0x01 start

这里不说保护模式的一些基本原理，假定看官已经知道了。

下面正式进入主题： 如何开始呢？ IDT是由IDTR指定的

这里先用WINDBG手工分析下，然后编程实现。

0: kd> r idtr  idtr=8003f400

这个IDT有多大呢？

0: kd> r idtl idtl=000007ff

其实大小就是这个数加一。

地址找到了，大小找到了，关键是这个是啥结构，IDT长啥样呢？

0: kd> dt _KIDTENTRY ntdll!_KIDTENTRY    +0x000 Offset           : Uint2B    +0x002 Selector         : Uint2B    +0x004 Access           : Uint2B    +0x006 ExtendedOffset   : Uint2B

就这样。

就是这个结构的数组。

下面看看第一个成员。

0: kd> dt _KIDTENTRY 8003f400 ntdll!_KIDTENTRY    +0x000 Offset           : 0x3360    +0x002 Selector         : 8    +0x004 Access           : 0x8e00    +0x006 ExtendedOffset   : 0x8054

这个结构的具体的含义，请看Intel的手册或者相关的资料。

经过计算得出地址是：0x80543360

验证的方式之一:

0: kd> u 0x80543360 nt!KiTrap00: 80543360 6a00            push    0 80543362 66c74424020000  mov     word ptr [esp+2],0 80543369 55              push    ebp 8054336a 53              push    ebx 8054336b 56              push    esi 8054336c 57              push    edi 8054336d 0fa0            push    fs 8054336f bb30000000      mov     ebx,30h

看到了吧！显示的是正确的。

另一个办法是：

注意：要带参数，不然不显示NTOS*.EXE中的中断。

至此：X86上的一个CPU的IDT样例分析完毕。

至于剩余CPU的，X64的分析类似，具体的分析可以看附件。

也可以作为看官的作业题。作业完成算是看懂了本文。

下面简单说一下编码的注意事项：

1.首先是多CPU。

早期的Windows版本可以用内核导出的变量KeNumberProcessors。

高版本的可以搜索KeGet*或者KeQuery系列的函数。

2.附加/贴近CPU，具体的说是线程，可以参考：

KeSetSystemAffinityThread

KeRevertToUserAffinityThread

3.因为是底层的操作，大多是用汇编实现的，还好微软提供了：

__sidt 参见：http://msdn.microsoft.com/zh-cn/library/aa983358%28v=vs.120%29.aspx

另一个思路是用：KeGetPcr()。

这个在X86上可以自己实现，其实也是用封装的汇编指令。

X64上这个可以直接调用。

4.如果要HOOK，看看如下两个链接：

_disable https://msdn.microsoft.com/zh-cn/library/y14401ab(v=vs.90).aspx

_enable https://msdn.microsoft.com/zh-cn/library/ad820yz3(v=vs.90).aspx

5.具体的编码和处理就看你的了。

再补充点： 32位下IDTR指向的位置可以用结构：

// Special Registers for i386 typedef struct _X86_DESCRIPTOR {  USHORT  Pad;  USHORT  Limit;  ULONG   Base; } X86_DESCRIPTOR, *PX86_DESCRIPTOR; kd> dt _DESCRIPTOR 注意：64位下没有这个结构。 nt!_DESCRIPTOR    +0x000 Pad     : Uint2B    +0x002 Limit   : Uint2B    +0x004 Base    : Uint4B

64位下IDTR指向的位置可以用结构：

// Special Registers for AMD64. typedef struct _AMD64_DESCRIPTOR {  USHORT  Pad[3];  USHORT  Limit;  ULONG64 Base; } AMD64_DESCRIPTOR, *PAMD64_DESCRIPTOR; 1: kd> dt _AMD64_DESCRIPTOR 注意：运行环境是64位系统。 test!_AMD64_DESCRIPTOR    +0x000 Pad     : [3] Uint2B    +0x006 Limit   : Uint2B    +0x008 Base    : Uint8B
