Windows驱动_文件系统微小过滤驱动之二驱动的安装和加载

机会总是留给有准备的人，人生只不过有6到7次机会，极少数的人抓住了，大部分的人，让机会从自己的身边溜走。在机会还没有到来的时候，千万不要气馁，也千万不要放弃。首先，认清自己，很多人，其实都没有将自己认识清楚，就去认清别人，认清世界。人跟人都是不一样的，想要的也不一样。所以，请记住，认清自己。在认清自己的前提下，在机会没有到来的时候，往自己的目标去努力，厚积薄发。没有机会，创造机会。不要给自己留下任何客观原因，也不要给自己留下任何的退路。华山一条路，我们已经在这条路上了，不进，其实也没办法后退了，后面就是悬崖。我们要抱起这样的决心去加油，去努力，去奋斗！

Installing a Minifilter Driver

对于Windows XP以后的操作系统，你应该通过INF文件来安装你的微小过滤驱动。

但你不需要通过INF文件来安装你的全部产品，你也不必需要提供鼠标右键选项来安装你的驱动。

Creating an INF File for a Minifilter Driver

在INF文件中，文件系统过滤驱动通常包含如下的节：

Version (required)

DestinationDirs (optional but recommended)

DefaultInstall (required)

DefaultInstall.Services (required)

ServiceInstall (required)

AddRegistry (required)

DefaultUninstall (optional)

DefaultUninstall.Services (optional)

Strings (required)

开始于Windows Vista X64系统，包含非PNP(PNP)驱动，比如文件系统驱动(文件系统，原始过滤驱动，微小过滤驱动)为了加载和执行必须签名。

如下的规则只适用于文件系统驱动。

对于非PNP驱动的INF文件，包含文件系统驱动，不需要包含[Manufacturer]或[Models]节。

在WDK下面安装路径下的\bin\SelfSign的SignTool可以直接进行内部签名。对于启动运行驱动必须包含一个内部的签名。

对于给定的INF文件，Inf2cat命令行工具可以被用来为驱动包创建一个catalog(.cat)文件。catalog文件可以接收WHQL logo签名。

在管理员的权限下，没有签名的驱动仍然可以在X64的Windows Vista及其以后的系统上安装，但是加载会失败。

关于驱动签名通用的信息，可以看Driver Signing.

关于驱动签名的详细流程，可以看Kernel-Mode code sianing Walkthrough.

所有的内核部件，包含定制的内核开发工具，都必须签名，更多的信息，看 Signing Drivers during Development and Test (Windows Vista and Later).

Version Section (required)

Version节指定class和GUID来定义微小过滤驱动的所属类型：

[Version]
Signature = "$WINDOWS NT$"
Class = "ActivityMonitor"
ClassGuid = {b86dff51-a31e-4bac-b3cf-e8cfe75c9fc2}
Provider = %Msft%
DriverVer = 10/09/2001,1.0.0.0
CatalogFile =

Entry Value

Signature "$WINDOWS NT$"

Class “See File System Filter Driver Classes and Class GUIDs”.

ClassGuid “See File System Filter Driver Classes and Class GUIDs”.

Provider “In your own INF file, you should specify a provider other than Microsoft”.

DriverVer “See INF DriverVer directive”.

CatalogFile

DestinationDirs Section (optional but recommended)

文件拷贝的目的文件夹，12指定的是%windir%\system32\drivers，10指定的是%windir%

[DestinationDirs]
DefaultDestDir = 12
Minispy.DriverFiles = 12
