驅(qū)動(dòng)對(duì)象講解

一丶驅(qū)動(dòng)對(duì)象

1.1 結(jié)構(gòu)

在內(nèi)核中. 每一個(gè)驅(qū)動(dòng)模塊都是一個(gè)驅(qū)動(dòng)對(duì)象. 都有一個(gè) DRIVER_OBJECT結(jié)構(gòu)體代表. 可以想象成驅(qū)動(dòng)對(duì)象是一個(gè)進(jìn)程容器. 容納百川.
下面針對(duì)驅(qū)動(dòng)對(duì)象做一下簡單的成員輸出.以熟悉驅(qū)動(dòng)對(duì)象.

驅(qū)動(dòng)對(duì)象結(jié)構(gòu)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;                                                        //驅(qū)動(dòng)對(duì)象的起始地址ULONG DriverSize;                                                         //驅(qū)動(dòng)對(duì)象的大小PVOID DriverSection;                                                      //驅(qū)動(dòng)對(duì)象結(jié)構(gòu).可以解析為_LDR_DATA_TABLE_ENTRY  是一個(gè)鏈表存儲(chǔ)著下一個(gè)驅(qū)動(dòng)對(duì)象                                                   PDRIVER_EXTENSION DriverExtension;                                        //驅(qū)動(dòng)的擴(kuò)展信息.可以自定義存放我們的數(shù)據(jù)                           //// 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;                                    //驅(qū)動(dòng)對(duì)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;                              //驅(qū)動(dòng)對(duì)象的卸載地址PDRIVER_DISPATCH MajorFunction[IRP_MJ_MAXIMUM_FUNCTION + 1];

} DRIVER_OBJECT;typedef struct _DRIVER_OBJECT *PDRIVER_OBJECT;

1.2 輸出代碼輸出基本的驅(qū)動(dòng)對(duì)象信息

#include <ntddk.h>

	_In_ struct _DRIVER_OBJECT* DriverObject

}extern "C" NTSTATUS DriverEntry(
	_In_ PDRIVER_OBJECT  DriverObject,
	_In_ PUNICODE_STRING RegistryPath
){
	ULONG64 uImage = 0;
	DriverObject->DriverUnload = MyDriverUnLoad;
	DbgPrint("驅(qū)動(dòng)加載了開始打印輸出\r\n");
	DbgPrint("驅(qū)動(dòng)名字 = %wZ \r\n", DriverObject->DriverName);
	DbgPrint("驅(qū)動(dòng)起始地址 %x 大小 %x  結(jié)束地址 %x\r\n",
		DriverObject->DriverStart,

		uImage = ((ULONG64)DriverObject->DriverStart + DriverObject->DriverSize));
	DbgPrint("驅(qū)動(dòng)對(duì)象的卸載地址 = %p\r\n", DriverObject->DriverUnload);	//輸出驅(qū)動(dòng)對(duì)象的所有回調(diào)地址.
	DbgPrint("驅(qū)動(dòng)對(duì)象的IoControl回調(diào)地址 = %p\r\n", DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL]);

	DbgPrint("驅(qū)動(dòng)對(duì)象的關(guān)閉回調(diào)地址 = %p\r\n",DriverObject->MajorFunction[IRP_MJ_CLOSE]);

	DbgPrint("-------遍歷回調(diào)輸出------------\r\n");	//宏從DrverObject對(duì)象中查找for (auto i = 0; i < IRP_MJ_MAXIMUM_FUNCTION; i++)
	{
		DbgPrint("回調(diào)的IRP_MJ 調(diào)用號(hào) = %d 回調(diào)函數(shù)地址 = %p \r\n", i, DriverObject->MajorFunction[i]);
	}

	DbgPrint("執(zhí)行所有功能完畢");	return STATUS_SUCCESS;
}
