在上一篇中，我简单介绍编写了一个NT驱动空壳，这一篇中，将介绍如何自己编写一个驱动程序加载器，即使用编程的方法加载驱动，而不是使用工具。
我在上一篇中也提到了，驱动程序是通过服务加载的，我以前写过SCM（服务控制管理器）API的文章，详细介绍各函数的具体用法，详见：
[Win32] SCManager 服务控制管理器API（1）：http://blog.csdn.net/zuishikonghuan/article/details/47803033
[Win32] SCManager 服务控制管理器API（2）：http://blog.csdn.net/zuishikonghuan/article/details/47808805
加载NT驱动的基本步骤是：
1。获取SCM服务控制管理器句柄。
2。用CreateService创建驱动服务。
3。用OpenService获取服务句柄。
4。用StartService启动驱动服务。
5。用ControlService停止驱动服务。
启动驱动服务除了用StartService外，还有很多“非官方，非正式”的方法，比如使用Zw/NtLoadDriver，Zw/NtSetSystemInformation等
好了废话不多说，加载上一篇中的驱动，加载器源码如下，驱动为C:\mydriver.sys，驱动服务名为mydriver
#include <Windows.h>
BOOL WINAPI InstallService(LPCTSTR ServiceName,
LPCTSTR DisplayName,
LPCTSTR szPath,
DWORD StartType,
DWORD ErrorControl = SERVICE_ERROR_NORMAL,
DWORD ServiceType = SERVICE_WIN32_OWN_PROCESS){
SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_CREATE_SERVICE);
if (hSCManager != NULL){
SC_HANDLE hService = CreateService(hSCManager, ServiceName, DisplayName, SERVICE_ALL_ACCESS, ServiceType, StartType, ErrorControl, szPath, NULL, NULL, NULL, NULL, TEXT(""));
if (hService != NULL){
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return TRUE;
}
CloseServiceHandle(hSCManager);
return FALSE;
}
else return FALSE;
}
BOOL WINAPI DeleteService(LPCTSTR ServiceName){
SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_CONNECT);
if (hSCManager != NULL){
SC_HANDLE hService = OpenService(hSCManager, ServiceName, DELETE);
if (hService != NULL){
if (DeleteService(hService))
{
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return TRUE;
}
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return FALSE;
}
CloseServiceHandle(hSCManager);
return FALSE;
}
else return FALSE;
}
BOOL WINAPI StartService2(LPCTSTR ServiceName){
SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_CONNECT);
if (hSCManager != NULL){
SC_HANDLE hService = OpenService(hSCManager, ServiceName, SERVICE_START);
if (hService != NULL){
if (StartService(hService, 0, NULL))
{
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return TRUE;
}
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return FALSE;
}
CloseServiceHandle(hSCManager);
return FALSE;
}
else return FALSE;
}
BOOL WINAPI StopService(LPCTSTR ServiceName){
SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
SERVICE_STATUS svcsta = { 0 };
if (hSCManager != NULL){
SC_HANDLE hService = OpenService(hSCManager, ServiceName, SERVICE_STOP);
if (hService != NULL){
if (ControlService(hService, SERVICE_CONTROL_STOP, &svcsta))
{
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return TRUE;
}
CloseServiceHandle(hService);
CloseServiceHandle(hSCManager);
return FALSE;
}
CloseServiceHandle(hSCManager);
return FALSE;
}
else return FALSE;
}
int _tmain(int argc, _TCHAR* argv[])
{
InstallService(TEXT("mydriver"), TEXT("mydriver"), TEXT("C:\\mydriver.sys"), SERVICE_DEMAND_START, SERVICE_ERROR_IGNORE, SERVICE_KERNEL_DRIVER);
//SERVICE_KERNEL_DRIVER：驱动服务；SERVICE_DEMAND_START：手动启动
if (StartService2(TEXT("mydriver"))){
printf("驱动已经加载\n");
}
Sleep(3000);
if (StopService(TEXT("mydriver"))){
printf("驱动已经停止\n");
}
getchar();
return 0;
}效果和上一篇里的使用工具加载效果一样
