    - Building for XP and amd64 Hi all, I have the longhorn DDK and server2k3 DDK, I am unable to build for XP64 amd64 platform. Apparently I can't, but I don't know why, knowing that I have an AMD64 machine running XP64. I have to build for Server2k3-64 AMD64, and my driver binaries might not be runnable on XP64 (amd64). Any idea how to build for XP64 amd64 not ia64 ?? thx Tag: Netvmini Sample related question Tag: 65739

    - NDIS-device status Hi All, I am using passthru intermediate driver.I have written an application which on a connect(NDIS_STATUS_MEDIA_CONNECT) notification from my intermedaite driver, will send data using sockets. What i noticed is though the device status is connected(it throws a ballon saying LAN is connected) and it is assigned an IP, it takes some time(2 to 4 secs) to send packets.The NdisSend function which is called by my intermediate driver returns success and actually the data is not sent across network. Because of this behaviour send funtion of socket succeds but the data is not sent. But after 2 to 4 seconds i am able to send data.I am using intel's LAN card. could anyone tell me whether it is a hardware problem or is there any NDIS events which can tell me the card is ready for data transfer?

    - Driver verifier IO SYSTEM VERIFICATION ERROR 226 Hi, ALL! I got the following problem with my USB driver running on Windows XP SP2. Everything works fine, sleep, wake-up, hot-unplug, regular unplug, data transfers and so on, except when I try to shutdown the system with my device plugged in and, consequently, my driver loaded. System gets all the way through shutdown procedure, saves all unsaved data, blanks the screen and then turns it on back and displays the message from Driver Verifier "IO SYSTEM VERIFICATION ERROR (WDM DRIVER ERROR 226)". I never saw any problem during regular shutdown without Driver Verifier activated. I double-checked all my handlers - none of them leaves IRP uncompleted or not passed down the stack.

    - Memory card reader insertion/removal notification Hi, For a program I'm writing I need to detect the insertion/removal of media from removable media devices, and for that I'm using the WM_DEVICE_CHANGE Windows message. The problem is that while it works fine with CD/DVD devices and USB flash drives, it doesn't notify me when memory cards are inserted/removed from a card reader. The card reader behaves like a CD-ROM drive in that the letter is allocated when the reader is connected, then as cards are inserted their contents become available. I've tried different ways using the RegisterDeviceNotification API without success. I could use polling of course but it doesn't seem to me very efficient. I'm sure this should be possible because the Windows Explorer does somehow detect the changes. Does anybody know of a sure way (user/kernel mode) to receive those notifications? Thanks for any hint.

    - usbview.exe chooses invalid font The DDK includes sources for program usbview.exe. The DDK's build command builds an executable which targets some versions of the Win32 environment. The usbview program attempts to display a number of character strings. The contents of the character strings come from the Windows operating system as installed. But the usbview program neglects to use Windows APIs appropriately to choose fonts that can display the contents. As shown in a screenshot, usbview.exe chose two fonts, one lucky and one unlucky. Microsoft has some employees who could advise the authors of usbview (and perhaps other authors of DDK components) how to do better than this.

    - driver image path Hello, experts! Can you please clarify few things about driver image ops: 1. Is there a kernel API to obtain a path from which NT driver binary was loaded (similar to GetModuleNameEx in user mode)? 2. Is there are a kernel API to load NT kernel mode DLL dynamically (i.e. load DLL built with TARGET=EXPORT_DRIVER, as opposed to statically linking it, i.e. something similar to user-mode API LoadLibrary)? 3. Registry has a value, ImagePath, for every installed kernel-mode service (HKLM\System\CurrentControlSet\Serivices\<DriverName>\ImagePath). However, this value can be empty if CreateService specified NULL as image path parameter (this seems to be a valid value, though doc does not describes it). Does this mean that either ImagePath _must_ be specified, or driver _must_ be in systemroot\system32\drivers? 4. Is default kernel load path is as simple as \systemroot\system32\drivers, or there is more to it? And what about Win64, what is default path there? 5. I was not able to find any notes on this either in DDK or IFS kits help. Can you point a good information source on subject? 6. Any changes in this area for various NT versions? Is information on if/how this is to change in Longhorn is already available? Many thanks in advance for answer(s), ygs. Tag: Netvmini Sample related question Tag: 65710

    - Developing a Bitmap Printer Hi all, My aim is to develop a bitmap printer Here are some things that are puzzling me... 1) Can I extract raw image data from the postscript printer and convert it to viewable bitmap image? If yes, then where should I be ideally looking to get the image data...Renderer, spooler or somewhere else? Will the image data be stored in a buffer or in some memroy DC? 2)Should I try extracting data from the universal printer?will it be easier? If yes, then where exactly should I be looking for the image? 3)Can I solve my problem by changing the minidriver?or does it just control the printer features and has nothing to do with file image extraction? 4)Is a plugin required to get this done or will I need to change some existing code? 5)Once I get the 'raw' image, will I need to do some processing on it to convert it to bmp, like adding tags or such? I'm also hoping to develop a pdf printer, so if I go with the postscript printer I may need to just develop one printer in the long run. Any pointers and help in this direction will be much appreciated. -- ***ljose*** Tag: Netvmini Sample related question Tag: 65651

    - Pending IOCTLs and Slow User Mode Response I've written an NDIS IM driver that forwards notifications to a user-mode app via a pended IOCTL. The app has 32 threads that simply call DeviceIoControl and then queue the notification up for another consumer thread. The problem that I'm seeing is that under heavy stress, where the driver needs to notify the app, I see the number of IOCTLs plumbed by the app stop, with the result that the driver runs out of pending IOCTLS/IRPs. Each thread of the user mode app calls DeviceIoControl() in a non-overlapped manner. Would calling this with an overlapped structure (and opening the file with FILE_FLAG_OVERLAPPED) help?

    - Is this code SMP safe? Hi, I am new at driver programming. I was wondering is the following code is SMP safe or would I need spinlocks around the indicated statements. //My device extension declaration typedef struct _DEVICE_EXTENSION { PIRP pCurrIrp; BOOL start; KEVENT evIoctl; } DEVICE_EXTENSION, *PDEVICE_EXTENSION; //My Dispatch routine (called w/ PASSIVE_IRQL) NTSTATUS MyDispatchRoutine(..., IN IRP pIrp) { ... //myPdx points to my device extension ... switch (controlCode) { case IOCTL_GET: if (!myPdx->start) <====spinlocks around this needed? { //IoCompleteRequest with error and exit } if (myPdx->pCurrIrp) <====spinlocks around this needed? { //IoCompleteRequest with busy error and exit } ........ InterlockedExchangePointer((PVOID*)&myPdx->pCurrIrp, pIrp); //wake worker thread KeSetEvent(&myPdx->evIoctl, IO_NO_INCREMENT, FALSE); ....... break; case IOCTL_START: InterlockedExchange((LONG*)&(myPdx->start), TRUE ); .... ....//IoCompleteRequest with ok break; ..... ..... } } //My executive worker thread which is signalled by the IOCTL above // (called w/ PASSIVE_IRQL) void MyWorkerThread(void) { ...//myPdx points to my device extension PIRP pIrp; ... ...//Acquire mutex (stored in dev. extnsion; not shown) to serialize ...// this thread execution vs. other instances of this thread ... if (myPdx->bCaptureSound) <====spinlocks around this needed? { KeWaitForSingleObject(&myPdx->evIoctl, Executive, KernelMode, FALSE, NULL); KeClearEvent(&myPdx->evIoctl); pIrp = myPdx->pCurrIrp; <====spinlocks around this needed? ........ InterlockedExchangePointer((PVOID *)&myPdx->pCurrIrp, NULL); ........//do other stuff .......//release mutex acquired above for serialization } I have indicated where I am confused about the spinlock thing. For writing to any variables in my device extension I use the InterlockedXXX functions but during reading of those variables, do I need spinlocks or some other protection? My understanding is that any "regular" read statement (such as "pIrp = myPdx->pCurrIrp") comprises of multiple machine instructions (ie. non-atomic) during which the scheduler can swap out the process and another process can modify the data resulting in corruption. Is this reasoning correct?? On a uniprocessor system I have seen that the worker thread execution is interspersed with the dispatch routine. But since in the worker thread I am working with the pointer to myPdx->pCurrIrp called pIrp, the dispatch routine is free to modify myPdx->pCurrIrp. So things work out fine w/ no lost IRPs. I wonder if things would change in an SMP machine. I know I asked a mouthfull (screenfull?) and I appreciate all tips. Thanks & Regards, James Tag: Netvmini Sample related question Tag: 65619

    - SysHook and STATUS_ACCESS_VIOLATION Hi, Recently I've attempt to write a driver in order to hook any registry access using the KeServiceDescriptorTable and then subst the table entry with my function. If I use the this code only for logging (ie. RegMon) it's all ok, but if I try to modify the parameter all the Zwxx function give me a STATUS_ACCESS_VIOLATION: for example: - if the key that the application want to open is \Registry\Machine\Software\Test I create (ExAllocatePool) a new POBJECT_ATTRIBUTES and relative PUNICODE_STRING - then I call the RealZwOpenKey (the real KeServiceDescriptorTable's function) but If I do so the function give me the error. But, If I dehook the ZwOpenKey and the I call ZwOpenKey the Fn is Ok. But dehooking this Fn isn't good (some access could be lost). It seems that the real ZwOpenKey's code can't or don't want access the memory allocated by the driver... thank's Tag: Netvmini Sample related question Tag: 65602

    - Scannig issue of new SCSI devices Hello, I am writing a user application program to scan hundreds of SCSI drives been connected and/or removed. I use IOCTL_SCSI_RESCAN_BUS to force scan (suppose to invalidate the device list in SCSIPort driver) and then IOCTL_SCSI_GET_INQUIRY_DATA to get the new list. However I get the stale data (i.e the device list prior to the drives been connected and/or removed). After I call IOCTL_SCSI_RESCAN_BUS and IOCTL_SCSI_GET_INQUIRY_DATA several loops (each time the number of loops changes), IOCTL_SCSI_GET_INQUIRY_DATA returns the correct list of drives. Using the SCSI Analyzer it has been confirmed that IOCTL_SCSI_RESCAN_BUS send REPORT_LUNS, then several INQUIRY command (the correct data is returned for all the new drives connected). Is there any way to prevent getting the stale device list? Is there a way to force clear the stale device list in the scsiport driver?. This is a major issue for the application program as it does not know the number of loops it has to issue the IOCTLs to get all the new device list.

    - USBD_STATUS not in header Hello, A status code that is returned in the Isopacket[].Status field of the _URB_ISOCH_TRANSFER struct does not seem to be in the USBD status code enum. The value is 0xC000000E. What does this code means in the context of an isochronous USB OUT and IN transfer? Can someone relate this code to the TD status field that is called out in the OHCI specification? I am testing on an AMD system using WindowsXP SP2.

    - USB enumeration time in a production test environment I seem to recall a discussion thread regarding speeding up recognition/enumeration of new devices. The problem that needs to be solved is that it's taking from 7 to 20 seconds for a new device to become available for communication after power on connection. The folks at our production facility want this to happen more quickly. The port that we will be using can be dedicated to this function. The device VID, PID, and Version will be constant but the USB serial number will probably be changing. My inital reaction is that the amount of time needed for enumeration is determined by how much work the PnP manager has to do to figure out the correct driver. As I mentioned, I seem to remember a similar issue that was on the list, but a search of current articles doesn't seem to turn anything up. Does anyone remember this one?

    - Checked build Assert in EngLoadImage Hi All, I get this when I load a dll from my display driver in Win2k3 Checked build: *** Assertion failed: Section->Segment->u1.ImageCommitment != 0 *** Source File: d:\srvrtm\base\ntos\mm\sessload.c, line 239 Break repeatedly, break Once, Ignore, terminate Process, or terminate Thread (boipt)? The warning seems inert, and it all works if I ignore it. But still it worries me. Any ideas what might be causing this? I guess it must be some sort of problem with the dll image.

    - 1394 Raw Mode Addressing And Driver Verifier Hello All... I've been using 1394 raw mode addressing successfully but when I run the driver verfier I get a bug check when accessing the port driver to perform a raw mode io request. My guess this is because I'm using an address that wasn't obtained by using IoGetDeviceObjectPointer( ). I retrieve the port driver address by accessing the bus driver's PortDeviceObject element. As follows.... // Get the port driver object. This is the next to the lowest layer in the driver stack. // The port driver is used to send messages to a node other than the node // for which the lower driver object exists. pDeviceExtension->pPortDeviceObject = ((PNODE_DEVICE_EXTENSION)pDeviceExtension->pStackDeviceObject-> DeviceExtension)->PortDeviceObject; However, I don't know what the symbolic link is for the 1394 port driver. (driver file ohci1394.sys.) The symbolic link for the bus driver is known as \\device\1394BUS0. Does anyone know the symbolic link for the 1394 Port Driver? I need this since it's required as the first parameter in IoGetDeviceObjectPointer( ). Thanks, Scott Tag: Netvmini Sample related question Tag: 65549

    - Ways to anlayze crash dump files When I get a BSOD, I use Visual SOFTICE and a Kernel memory dump to try and trace the error. If one of my driver's function is in the stack trace, I can goto its source and try to find the error. My problem starts when I don't see my driver in the stack trace, and even when I disassemble "Parameter 4: Address of instruction executing" I can't see any of my driver's function. Any way I can get more informant from the dump? Does WinDbg can be more helpful in analyzing dump files ? Any way to know if the win32 user mode app caused the crash? (Then I need to use a complete memory dump?) Any other tips on debugging BSODs? Tag: Netvmini Sample related question Tag: 65526

Hi All,

I have changed the Netvmini DDK sample to read a packet into a usermode
application from the miniport driver's TCB memory. The original sample
send a packet via NICsendPacket to another Netvmini instance installed
and receive the same packet again. So now I only want to use 1 instance
of the miniport and not be dependend on more than one miniport. I have
now disabled the receive timer (NICIndicateReceiveTimerDpc) and remove
all the destination device code from NICSendPacket function but this
causes a driver failure when the packet is copied to the TCB.

1. Any idea how to overcome this problem?

2. What method can the driver use to notify the usermode application of
a new packet to read?

Thanks for you time and help!
Amos
