How can I install a WDF Driver WITHOUT using .INF files and WIHTOUT using CoInstaller-s ?
I just want to install it the simple, old way (an app that calls CreateService,StartService,...). But if I do that, i get a "File not found" error message, and it doesn't even say which file isn't to be found 
I think Microsoft did a very good think releasing wdf-kmdf, but the installation procedure is just too complicated (INF files and WDF coinstallers aren't fun!). Also, using AddHardware everytime I compile the driver is time consuming.
Thanks.
PS: Please excuse my english as it's not my first language

Hi!
Maybe the kernel API ZwCreatefile() can open an exe file,but,in the driver program,how to get the drive-lettle of the pen disk where the exe file is stored? Cause the system may assign different drive-lettle for the pen disk each time the pen disk pluged in pc.
Thanks!

Hi!
User model application use ShellExecute() to open a exe file,so what
the relative kernel API driver use to open a exe file?
Thanks!

ZwCrteateFile() is the kernel call to open any file.

How to open a **.exe file in a wdm driver program?
Hi!
I had copied a **.exe file in a pen disk,and I wish that everytime I attach this pen disk
to pc the **.exe file can auto run.
I know that system can auto run this **.exe file if I create a autorun.inf in the pen disk.
But now I wanna my pen disk driver program can run this **.exe file instead of system.
So my question is:
If it has the possibility to create a user model process in a WDM driver program,that's to
say,if the wdm driver can invoke a user model API?
Thanks!

I am going to advise that this cant be done.
The correct way to do this is to have a serivce running on the PC that has registered for WM_DEVICCHANGE messages. When a device arrives it is interested in is plugged in it then runs
the exe.
It might be possible to run the exe from a driver, but, I dont know how. It might require using undocumented kernel API functions which give portaqbility problems.

Hi!,fat_boy^_^
Yes,I agree with you that it's a correct way to run a service on pc.
But now I wanna have a try to realize it from the driver.
Maybe the kernel API ZwCreatefile() can open an exe file,but,in the driver program,how to get the drive-lettle of the pen disk where the exe file is stored? Cause the system may assign different drive-lettle for the pen disk each time the pen disk pluged in pc.
Can you give me some advice,fat_boy?
Thanks!

It is not just a case of opening an exe.
You have to create a process, map the exe into it and call its main function.
At least that is what I am guessing at, god knows how you will do it in reality but you would be mimicing part of the OSs functionality.
If you want to get somethinbg working that is reliable, go the service route that waits for device arrival, via WM_DEVICECHANGE messages and starts the app.
We had to do exactly this for one of our products and, as a driver writter, I was deflecting all kinds of comment by application writers about how easy it is for a driver to do this, with me replying, 'go on then, you do it, and get it through WHQL, and have it run on todays OS and tomorrows'
We went the serive route and so should you.

Where should we create the process,in our driver program? Is it possible to create a process,which maybe an user mode app,in our kenel mode driver program?
fat_boy,you know that we can create or open a data file stored on harddisk by using the kennel api
ZwCreatefile,so,if we can open an exe file,such as C:\Program Files\Internet Explorer\IEXPLORE.EXE,by useing ZwCreatefile(maybe some other kernel api) in our driver program,then,the only problem is how to get the drive-lettle of the pen disk where the actual exe
file stored.
So,what about your apinion?
Thank you very much!

Oh yes, running a process from KernelMode CAN be done, though it is complicated.. Here it is:
By: valerino
I don't think this code needs any comment.
Say welcome to usermode calls in kernel land..... with this technique you can even call MessageBox from inside your driver.
No more ugly non-working phrack samples, this is the real stuff 
1) The APC injector
//************************************************************************
// NTSTATUS UtilInstallUserModeApcForCreateProcess(char* CommandLine, PKTHREAD pTargetThread, PKPROCESS pTargetProcess)
//
// Setup usermode APC to execute a process
//************************************************************************/
NTSTATUS UtilInstallUserModeApcForCreateProcess(char* CommandLine, PKTHREAD pTargetThread, PEPROCESS pTargetProcess)
{
PRKAPC pApc = NULL;
PMDL pMdl = NULL;
PVOID MappedAddress = NULL;
ULONG size;
KAPC_STATE ApcState;
PKEVENT pEvent = NULL;
// check params
if (!pTargetThread || !pTargetProcess)
return STATUS_UNSUCCESSFUL;
// allocate memory for apc and event
pApc = ExAllocatePool (NonPagedPool,sizeof (KAPC));
if (!pApc)
return STATUS_INSUFFICIENT_RESOURCES;
pEvent = ExAllocatePool (NonPagedPool,sizeof (KEVENT));
if (!pEvent)
{
ExFreePool (pApc);
return STATUS_INSUFFICIENT_RESOURCES;
}
// allocate mdl big enough to map the code to be executed
size = (unsigned char*)UtilUserApcCreateProcessEnd - (unsigned char*)UtilUserApcCreateProcess;
pMdl = IoAllocateMdl (UtilUserApcCreateProcess, size, FALSE,FALSE,NULL);
if (!pMdl)
{
ExFreePool (pEvent);
ExFreePool (pApc);
return STATUS_INSUFFICIENT_RESOURCES;
}
// lock the pages in memory
__try
{
MmProbeAndLockPages (pMdl,KernelMode,IoWriteAccess);
}
__except (EXCEPTION_EXECUTE_HANDLER)
{
IoFreeMdl (pMdl);
ExFreePool (pEvent);
ExFreePool (pApc);
return STATUS_UNSUCCESSFUL;
}
// map the pages into the specified process
KeStackAttachProcess (pTargetProcess,&ApcState);
MappedAddress = MmMapLockedPagesSpecifyCache (pMdl,UserMode,MmCached,NULL,FALSE,NormalPagePriority);
if (!MappedAddress)
{
// cannot map address
KeUnstackDetachProcess (&ApcState);
IoFreeMdl (pMdl);
ExFreePool (pEvent);
ExFreePool (pApc);
return STATUS_UNSUCCESSFUL;
}
// copy commandline
memset ((unsigned char*)MappedAddress + 160, 0, 260);
memcpy ((unsigned char*)MappedAddress + 160, CommandLine,strlen (CommandLine));
KeUnstackDetachProcess (&ApcState);
// initialize apc
KeInitializeEvent(pEvent,NotificationEvent,FALSE);
KeInitializeApc(pApc,pTargetThread, OriginalApcEnvironment,&UtilUserApcCreateProcessKernelRoutine,
NULL, MappedAddress, UserMode, (PVOID) NULL);
// schedule apc
if (!KeInsertQueueApc(pApc,pEvent,NULL,0))
{
// failed apc delivery
MmUnlockPages(pMdl);
IoFreeMdl (pMdl);
ExFreePool (pEvent);
ExFreePool (pApc);
return STATUS_UNSUCCESSFUL;
}
// and fire it by manually alerting the thread (for reference, this set the KTHREAD.ApcState.KernelApcInProgress)
// beware, this could be not compatible with everything ..... it works on 2k/XP anyway, tested on SP2 too.....
*((unsigned char *)pTargetThread+0x4a)=1;
// apc is fired, wait event to signal completion
KeWaitForSingleObject (pEvent,Executive,KernelMode,FALSE,NULL);
// free event
ExFreePool (pEvent);
// unmap and unlock pages / mdl . Note that there's no need to call MmUnmapLockedPages on paged locked with MmProbeAndLockPages,
// since MmUnlockPages does this for us automatically.
MmUnlockPages(pMdl);
IoFreeMdl (pMdl);
return STATUS_SUCCESS;
}
2) This routine just frees the APC allocated memory as soon as it's fired
//************************************************************************
// VOID UtilUserApcCreateProcessKernelRoutine( IN struct _KAPC *Apc, IN OUT PKNORMAL_ROUTINE *NormalRoutine,
// IN OUT PVOID *NormalContext, IN OUT PVOID *SystemArgument1, IN OUT PVOID *SystemArgument2 )
//
// This routine just frees the APC
//************************************************************************/
VOID UtilUserApcCreateProcessKernelRoutine( IN struct _KAPC *Apc, IN OUT PKNORMAL_ROUTINE *NormalRoutine,
IN OUT PVOID *NormalContext, IN OUT PVOID *SystemArgument1, IN OUT PVOID *SystemArgument2 )
{
PKEVENT pEvent;
KDebugPrint (1,("%s APC KernelRoutine called, freeing APC.\n", MODULE));
// free apc
ExFreePool(Apc);
// set event to signal apc execution
pEvent = (PKEVENT)*SystemArgument1;
KeSetEvent (pEvent,IO_NO_INCREMENT,FALSE);
}
3) This is the usermode routine launched by the APC. It gets Kernel32 base and find imports by a hash, then calls winexec (simpler
than call createprocess, but anyway this is just an example....).
Use this NASM macro to calculate the needed hashes for whatever usermode functions you may need to call :
;
; HASH - NASM macro for calculating win32 symbol hashes
; Usage: HASH instruction, 'SymbolName'
;
%macro HASH 2
%assign i 1 ; i = 1
%assign h 0 ; h = 0
%strlen len %2 ; len = strlen(%2)
%rep len
%substr char %2 i ; fetch next character
%assign h \
(h<<0x13) + \
(h>>0x0d) + \
char ; rotate and add
%assign i i+1 ; increment i
%endrep
%1 h ; return instruction with hash
%endmacro
I can't remember where i got this shellcode, it was lying already modified on my hd for long time. Anyway it's not mine....
i just rearranged it to my needs. Whoever recognizes it as his code, email me at valeryno@hotmail.com and i'll put the proper credits
//************************************************************************

//
// This is where we call createprocess. We're in usermode here

I dont know what the hell has happend to my PC  . after winXp is loaded, few(varies from two minutes to 20 min) minutes later gets rebooted as if you "unplug-n-Plug" the power cable. Before restarting, the monitor flickrs, the small light in the mouse dims and brightens.. then.. f*cking restart.
I changed SMPS.
I Gave motherboard for service.
I removed mouse.
I removed NIC.
I removed USB.
i removed everything.
It works well in DOS command prompt (and in the BIOS screen atleast)
what could be the problem ? someone please help me get a clue.

can a virus go down to that level?? if its in DOS i'd believe it.

The only thing i didn't replace was the RAM. damn.. see what i do today. i'll surely burn it on fire. grrrrrrrr.. that took me almost a month to identify.. almost damaging my HDD and getting the blame on my innocent SMPS, MotherBoard and even Mouse( ).. i even thought the problem is with the PS2 connector with the board( i have a old 810 board)... hmm i hope this would be the judgement day. thanks again Marc.

This could also be a temperature problem. Check the fans and heat sinks in your machine.
Software Zen: delete this;

Yup, all fans are running. and moreover, in 2 minutes how does it get that hot??
