获取CPU每个核心的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：
0: kd> !idt -a

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：
1 // Special Registers for i386
2 typedef struct _X86_DESCRIPTOR { 3 USHORT Pad;
4 USHORT Limit;
5 ULONG Base;
6 } X86_DESCRIPTOR, *PX86_DESCRIPTOR;
7
8 kd> dt _DESCRIPTOR 注意：64位下没有这个结构。 9 nt!_DESCRIPTOR 10 +0x000 Pad : Uint2B 11 +0x002 Limit : Uint2B 12 +0x004 Base : Uint4B
64位下IDTR指向的位置可以用结构：
1 // Special Registers for AMD64.
2 typedef struct _AMD64_DESCRIPTOR { 3 USHORT Pad[3];
4 USHORT Limit;
5 ULONG64 Base;
6 } AMD64_DESCRIPTOR, *PAMD64_DESCRIPTOR;
7
8 1: kd> dt _AMD64_DESCRIPTOR 注意：运行环境是64位系统。 9 test!_AMD64_DESCRIPTOR 10 +0x000 Pad : [3] Uint2B 11 +0x006 Limit : Uint2B 12 +0x008 Base : Uint8B
不说了：看垃圾代码吧！ 注释以上的结构摘自：WRK。 书于匆忙之后，如有不足请指正。
