驱动对象讲解

一丶驱动对象

1.1 结构

在内核中. 每一个驱动模块都是一个驱动对象. 都有一个 DRIVER_OBJECT结构体代表. 可以想象成驱动对象是一个进程容器. 容纳百川.
下面针对驱动对象做一下简单的成员输出.以熟悉驱动对象.

驱动对象结构如下:

typedef struct _DRIVER_OBJECT {CSHORT Type;CSHORT Size;//// The following links all of the devices created by a single driver// together on a list, and the Flags word provides an extensible flag// location for driver objects.//PDEVICE_OBJECT DeviceObject;ULONG Flags;//// The following section describes where the driver is loaded.  The count// field is used to count the number of times the driver has had its// registered reinitialization routine invoked.//PVOID DriverStart;                                                        //驱动对象的起始地址ULONG DriverSize;                                                         //驱动对象的大小PVOID DriverSection;                                                      //驱动对象结构.可以解析为_LDR_DATA_TABLE_ENTRY  是一个链表存储着下一个驱动对象                                                   PDRIVER_EXTENSION DriverExtension;                                        //驱动的扩展信息.可以自定义存放我们的数据                           //// The driver name field is used by the error log thread// determine the name of the driver that an I/O request is/was bound.//UNICODE_STRING DriverName;                                    //驱动对象的名字//// The following section is for registry support.  This is a pointer// to the path to the hardware information in the registry//PUNICODE_STRING HardwareDatabase;//// The following section contains the optional pointer to an array of// alternate entry points to a driver for "fast I/O" support.  Fast I/O// is performed by invoking the driver routine directly with separate// parameters, rather than using the standard IRP call mechanism.  Note// that these functions may only be used for synchronous I/O, and when// the file is cached.//PFAST_IO_DISPATCH FastIoDispatch;PDRIVER_INITIALIZE DriverInit;PDRIVER_STARTIO DriverStartIo;PDRIVER_UNLOAD DriverUnload;                              //驱动对象的卸载地址PDRIVER_DISPATCH MajorFunction[IRP_MJ_MAXIMUM_FUNCTION + 1];} DRIVER_OBJECT;typedef struct _DRIVER_OBJECT *PDRIVER_OBJECT;

1.2 输出代码输出基本的驱动对象信息

#include VOID MyDriverUnLoad(        _In_ struct _DRIVER_OBJECT* DriverObject){        DbgPrint("驱动卸载了\r\n");}extern "C" NTSTATUS DriverEntry(        _In_ PDRIVER_OBJECT  DriverObject,        _In_ PUNICODE_STRING RegistryPath){        ULONG64 uImage = 0;        DriverObject->DriverUnload = MyDriverUnLoad;        DbgPrint("驱动加载了开始打印输出\r\n");        DbgPrint("驱动名字 = %wZ \r\n", DriverObject->DriverName);        DbgPrint("驱动起始地址 %x 大小 %x  结束地址 %x\r\n",                DriverObject->DriverStart,                DriverObject->DriverSize,                uImage = ((ULONG64)DriverObject->DriverStart + DriverObject->DriverSize));        DbgPrint("驱动对象的卸载地址 = %p\r\n", DriverObject->DriverUnload); //输出驱动对象的所有回调地址.        DbgPrint("驱动对象的IoControl回调地址 = %p\r\n", DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL]);        DbgPrint("驱动对象的读回调地址 = %p\r\n",DriverObject->MajorFunction[IRP_MJ_READ]);        DbgPrint("驱动对象的写回调地址 = %p\r\n",DriverObject->MajorFunction[IRP_MJ_WRITE]);        DbgPrint("驱动对象的创建回调地址 = %p\r\n",DriverObject->MajorFunction[IRP_MJ_CREATE]);        DbgPrint("驱动对象的关闭回调地址 = %p\r\n",DriverObject->MajorFunction[IRP_MJ_CLOSE]);        DbgPrint("-------遍历回调输出------------\r\n");    //宏从DrverObject对象中查找for (auto i = 0; i < IRP_MJ_MAXIMUM_FUNCTION; i++)        {                DbgPrint("回调的IRP_MJ 调用号 = %d 回调函数地址 = %p \r\n", i, DriverObject->MajorFunction[i]);        }        DbgPrint("执行所有功能完毕"); return STATUS_SUCCESS;}
