    - How to force discarding of invalid cached partition contents? A USB hard drive contains a FAT32 partition. Sometimes the partition has a drive letter assigned. When the partition has a drive letter, Windows Explorer and/or some other parts of Windows XP read and cache a portion of the contents. I write part of the partition myself, so I want to force Windows to abandon its cached contents. I call DeviceIoControl several times. FSCTL_LOCK_VOLUME, FSCTL_DISMOUNT_VOLUME, IOCTL_VOLUME_OFFLINE, IOCTL_VOLUME_ONLINE, and FSCTL_UNLOCK_VOLUME. All of these succeed. WinIoCtl.h doesn't define IOCTL_VOLUME_OFFLINE and IOCTL_VOLUME_ONLINE, but MSDN implies that these are supposed to be available to user mode applications, so I define them myself and DeviceIoControl reports success. After that, I have found two ways to do manual operations to force Windows to abandon its cached contents. One is to use Computer Administrator - Disk Administrator, remove the drive letter from the partition, and reassign the drive letter to the partition. The other way is to open a command prompt and run CHKDSK /F, which finds no errors but which somehow persuades Windows XP to discard its cache. If I omit the /F then the obsolete contents remain in the cache, after which Windows proceeds to corrupt the partition and then the next CHKDSK /F adjusts errors (but lost data remain lost). Now I want to do this programmatically. I wonder why obsolete contents remain in the cache after IOCTL_VOLUME_OFFLINE and IOCTL_VOLUME_ONLINE, but continue trying anyway. I added calls to BroadcastSystemMessage with DBT_DEVICEREMOVECOMPLETE and DBT_DEVICEARRIVAL. These report success. Furthermore if Windows Explorer was displaying the partition before these operations, I can see Windows Explorer respond by removing that partition from its display, displaying the contents of another partition, and then restoring the drive letter and icon in the left hand pane though the right hand pane continues displaying the other partition that it had switched to. So I think that DBT_DEVICEREMOVECOMPLETE and DBT_DEVICEARRIVAL have some amount of effect. But when I click on that drive letter in Windows Explorer, it still displays obsolete cached information, and creating a new file causes corruption in the partition. What does it take to force Windows to discard obsolete cached data? Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107756

    - Reference Counting StartService/ControlService On Legacy Driver Hi All, I have what I imagine is a common problem: I have a legacy NDIS driver that is started/stopped dynamicaly by StartService/ControlService. The problem is that user-mode EXE's, in multiple user accounts, need to start, and perhaps stop, the service, multiple times, simultaneously, during their normal courses of execution. Unfortunately, it seems that the policy of: ControlService (hDriverService, SERVICE_CONTROL_STOP, &status); ...is to force a true stop of the service, always, irrespective of how many StartService calls were invoked to start the driver. I could do what I am doing now, which is simply let the driver stay loaded until reboot, but I was wondering what is the proper way to handle this situation. TIA, -Le Chaud Lapin- Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107753

    - Monolithic Storage Driver - Partition Creation Failure Using diskpart or the DM UI, initializing our drive fails to create a basic disk (MBR style) intermittently. This failure is timing sensitive and can change across reboots or even insertion of benign dbg traceouts. We have a monolithic storage driver for our device. We see the failure across all versions of Windows. The following show's a failure case using the diskpart CLU. DISKPART> select disk 1 Disk 1 is now the selected disk. DISKPART> clean DiskPart succeeded in cleaning the disk. DISKPART> create partition primary The disk management services could not complete the operation. ******* When using the DM UI, we get the following popup error message when trying to init the disk - "The operation did not complete. Check the System Event Log for more..." in the event log there is a entry saying the following: "VDS fails to write boot code on a disk during clean operation. Error code: 57@02070006." We have turned on debug msgs in the VDS driver and found the following trace out when the partition creation fails: LEAVE CBasicPack::FindDiskByNotificationHandle() INFO: VDS(0X02040002): WM_DEVICECHANGE: wParam=32774 lParam=12385696 ---->>>> ERROR: CVdsPack::ReadFile or WriteFile failed: 57 ENTER CVdsCriticalSection::~CVdsCriticalSection() TRACE: TMP: GUID_IO_VOLUME_MOUNT event received. ENTER LogEvent() LEAVE CVdsCriticalSection::~CVdsCriticalSection() INFO: WM_DEVICECHANGE: wParam=32774 lParam=14482848 ERROR: Event logged: C200000B LEAVE CBasicProvider::OnDiskLayoutChange() INFO: TMP: GUID_IO_VOLUME_MOUNT event received. The 57 error code logged to the event log is the same error code returned by the read/write failure shown above. We have verified that we are not returning failure in any read/write request and that we are not corrupting disk data. In fact, after a reboot, the disk seems to have been successfully initialized, with the MBR data appearing to be correct. It appears to be some timing interaction with two different threads when the partition is being created. They are both from partmgr. We have traced it to the following decision point in partmgr: RtlDeleteElementGenericTableAvl RtlLookupElementGenericTableFullAVL signature = CheckSignature() if (signature == successful) ---> calls PmWritePartitionTableEx gets called and partition is created if (signature != successful) ---> partition is NOT created We have a very detailed Visio flow control document that shows the details of a success versus a failure case that I would be happy to forward to anyone interested in helping out. Thanks for any help and/or ideas. Drex Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107745

    - Security enforcement for a 1394 IOCTL I use an IOCTL request (Create 1394 virtual device) that passes from my 1394 driver to lower windows drivers in 1394 stack where a virtual device is created. This IOCTL is successful in Windows Vista only if the application is "Run as administrator". I want to modify this behaviour and make it available for normal application (without bumping to admin). I dont know whether it is possible. Where is security enforced? Is it possible to change at application level by opening the device handle with a NULL security descriptor? Can I modify from in AddDevice() from my driver? Thanks, Raj Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107740

    - DrvTextOut Accessing Font information I'm aware that in the DrvTextOut callback, I can somewhat retrieve information about the font and its glyphs from pfo member of the parameters, which are configured in the DrvQueryFont callback. However, I have not exported this callback in my DDI hooks array, yet I'm getting some numbers for the pfo members when I investigated this pointer in the debugger. As a result, I'm not sure what to make out of this. What is the difference between GDI and driver realized fonts? Basically, after reading the DDK documentation, I'm still very confused on how I can access the information in the LOGFONT structure passed in CreateFontIndirect function call in the client application. Any comments on this would be muchly appreciated. Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107729

    - capturing emf spool file for later replay. Hi, I am trying to capture the emf spool file, so that I can replay it later on different print drivers. I'm trying to do this to simpify automated regression testing of my driver. While I have found a number of websites that say its possible, and some programs that save a print job as emf, I haven't found any real details, and as I understand it, spool file emf is a modified, undocumented version of emf so something I download of the net might not work.

    - Standard user can not do driver uninstallation in control panel in Vista I get a problem with the DIFxAPP.msm when building an installer. The merge module comes from DIFx 2.1. We use DIFxAPP.msm to install driver in our installer. After we build the installer (Setup.exe, SPI.msi, Data1.cab) with the merge module, we login Vista 32 with an administrator account, and finish the installation with setup.exe, the driver can be installed correctly. Then we log out, and re-login as a standard user, and do uninstallation in control panel. In the uninstallation process, there will be an error and the process rolls back. Later under the standard user account we use SPI.msi do uninstallation in command line, and the process is same with that in control panel. According the log we catched from command line, the error come from custom action "UninstallDriverPackages" that comes from the DIFxApp.msm Following is the prompt information from the log. DIFXAPP: UninstallDriverPackages() DIFXAPP: 'CustomActionData' property 'DIFxApp Version' is 2.1. DIFXAPP: 'CustomActionData' property 'UI Level' is 3.

    - W2K package resubmission We have a USB driver package we had qualified way back in mid 2005. It wasn't logo'd; we just needed a signed device driver. We now have a couple more devices serviced by the driver and wish so add their IDs to the INF file, which of course invalidates that .cat file. Anyone know if we can submit the old package with the new INF file and get an updated .cat file without going through the logo program (which is the only thing I see links to)? Paying the driver signing fee will be fine, I would just really prefer not to have to go through the whole (NEW!) test cycle again for an already qualified driver. Thanks!

    - NDIS MINIPORT MiniPortSend() not called after ASSOC Hi folks, in my own WLAN Miniport Driver, NDIS sometimes does not start transmitting the 1st data packet (usually the 1st key of the WPA/PSK EAPOL 4-way-handshake). I have absolutely no idea, why What I have is: After getting the interrupt from WLAN Chip, which is reporting "okay from 802.11 ASSOC", I send to NDIS: NdisMIndicateStatus ( Adapter->MyAdapterHdl, NDIS_STATUS_MEDIA_DISCONNECT, NULL, 0 ); NdisMIndicateStatusComplete ( Adapter->MyAdapterHdl ); Is this _not_ enought to force NDIS the start of Tx/Rx? The last status was _not_ NDIS_STATUS_RESSOURCES, so NdisMSendComplete() could also not be the reason, right? in fact, I get this problems right after rebooting the device, so the Miniport can not be in NDIS_STATUS_RESSOURCES state, I assume... BTW: the driver is currently build for WinCE5.0, which is NDIS 5.1. The port for WinXP is long time not maintained and the hardware is also no longer avail for desktop. Thus, I cannot check if I have the same problems under any WinNT. Any help is highly appreciated! -- Mai Kee Reiss Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107716

    - Troubleshooting Sleep Issues - Continued Volodymyr, I let this sit for a biut, so I'm re-posting. I fiddled around with WinDBG on a test machine. I use WinDBG quite frequently to analyze crash reports, but that's about the extent of my knowledge with it. I was able to put Windows into the /debug state, no problem. Rebooted, then opened up WinDBG, here's where I get a little lost. I'm not sure from the instructions whether I'm supposed to be doing a kernel debug, or attaching to a process. It also sounds like they are doing a remote debug, how would I do this? From another machine, connected to the target machine via the Serial port, or firewire/USB? I did a kernel debug locally, however I can't set the breakpoint to GetThreadExecutionState when in kernel mode. Unless I'm doing it wrong. I was however able to attach the debugger to the shell, explorer.exe. This did allow me to set that breakpoint and monitor the call traces. But it almost seemed to lock up at times & was unstable. So I believe I really need to do a remote debug, found Instructions on how-to do that. However it doesn't really seem to apply to my particular situation, as I don't have a specific app. or dll that I'm debugging. Any help on executing this would be great. Thx. a bunch. =) -- Thx.

    - USB - send data using bulk pipe Hi all, I would like to send and receive data using bulk pipes. My data would exceed the max. packet size of my full speed device (64B). On the host side I'm using WinUsb. Is it possible to send data, larger than 64B using one call to WinUsb's WinUsb_WritePipe, or should I split the data to fit into a 64B data packets? What about receiving data from the device, Is it possible to send "a big buffer" (>64B) using one call to WinUsb's API?

    - Regarding CPSUI Hi, I have been implementing a printer interface DLL which uses normal Win32 dialog based property pagesinstead of CPSUI based property pages and noticed following issues. 1. The PROPSHEETUI_REASON_SET_RESULT is never called in case of Win32 dialog based property pages. I am not sure whether there is any way to make this get called. 2. If I open from control panel -> printer properties, the settings changes are not saved in the DEVMODE due to problem 1. I have to explictly save the settings using GetPrinter() functions. I believe this also is related to (1) What are the additional things to be done when non-CPSUI based printer property pages are used? Thanks.

    - How do i send a captured data to print spooler for printing. Hi, let me explain you what actually am trying to do. writeprinter() function in a rendering plug-in of a Unidrv printer driver if implemented , enables us to capture the out put data generated by the Unidrv printer driver. So am trying to implement this function there by capturing the data the driver is giving out. So , for this i have written a function which opens a file captures the driver data .But to my surprise am not able to get any data ,but NULL is being captured. You can see my implementation as below.. HRESULT __stdcall COemUni2:: WritePrinter( PDEVOBJ pdevobj, PVOID pBuf, DWORD cbBuffer, PDWORD pcbWritten ) { BOOL bResult; bResult = GetDriverOutput(pdevobj, pBuf, cbBuffer, pcbWritten); if(bResult) { return S_OK; } return S_FALSE; } BOOL GetDriverOutput(PDEVOBJ pdevobj, PVOID pBuf, DWORD cbBuffer, PDWORD pcbWritten) { FILE *fp1; char* sFile; sFile = "E:\\result.txt"; HANDLE hFile1 = CreateFile((LPCTSTR)sFile, GENERIC_WRITE | GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); if( (fp1 = fopen( sFile, "w" )) == NULL ){ return FALSE; } fprintf(fp1, "%s", pBuf); fclose(fp1); CloseHandle(hFile1); return TRUE; } This is what i implemented. I dont know why NULL is being captured .... Now my objective is to capture the correct out put data generated by Unidrv driver and also i should send this data what ever captured ,to the print spooler for printing and this should be done automatically by my function . So please throw some light , by giving me some idea on how do i do this and please let me know where exactly am going wrong. Thanks in advance for your time and help. Please let me know if you still want any more details from my side. Thanks, Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107695

    - Windows driver debugging using 1394 Hello all !!! I am new to windows device driver development... I want to setup the remote debugging using 1394 fireware card. I followed the steps in the document DW04001_WINHEC2004. In the host side I installed the debugging tool (version 6.9.3.113). But as discussed in the document when i started WinDbg wih 1394 enabled in channel 10 it was not installing two drivers ,it was installing only one driver - 1394 windows debug driver (kernel mode) (1394kdbg.sys). It was not installing 1394 windows debug XP driver, and the Windbg application was showing the message "Waiting to reconnect". I followed the same steps in the document in target side and restarted the target machine.. But it was not connecting to the host.. I used the 6-6 pin to connect host and target. Anyone could you please help me... is it necessary to install 1394 windows debug XP driver in host side to make it work ???.. Both Host and Target machine is running Wondows XP SP2. Could you please give your valuable suggestion for to make it work ???? Thanks in advance Biju Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107691

    - WinUsb_Initialize failing with ERROR_BAD_DEVICE Hi. I've got a driver based on the FX2 sample. When plugging in the hardware, the my driver starts loading and wudfhost is running. I've used the debugger to break into it and see my driver calling IWDFUsbTargetFactory::CreateUsbTargetDevice. That's failing with ERROR_BAD_DEVICE. According to the docs, this would be an error code returned by WinUSB_Initialize. The device name is \\.\UMDFCtrlDev-3e5e32b1-51b0-11dd-813d-0010dc4ece8d from a previous call to IWDFDevice::RetrieveDeviceName. I've even tried taking the FX2 driver source as is and just modifiying the vendor ID and PID to match my hardware, realizing that it would fail later in the process after WinUSB initialized. The result is the same. Any guesses as to what I might have wrong? Thanks, Steve Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107690

    - How to get enumerator's DO (due to possible system bug)? Hi. Is there any way to get the device object of the bus driver whoâ??s created the PDO to which our device is attached? To be precise, I have a legacy PCI device which works more reliably with old applications if itâ??s been assigned legacy I/O addresses (i.e. 12-bit ISA ports below 0x1000). To achieve this, I use the PCI bridge subtractive-decode: add extra resource lists with desired resources to the resource requirements list and then rely on PnP Manager to assign one if available, or just use boot resources in case of a positive-only bridge or if resources arenâ??t available. However, on one particular system, Iâ??ve hit a problem where although the bridge does not support subtractive-decode (based on â??How Windows Identifies and Supports Bridge Typesâ?? section of â??Supporting Subtractive PCI-to-PCI Bridges in Windowsâ??), PnP manager still sends me resources which are only available for a subtractive-decode bridge. This apparently ends up in a crash and possibly is a bug in PnP/PCI driver(?). As a workaround, Iâ??m trying to get the device object of the underlying PCI bridge (which is on a different stack) and use it to read the PCI config space of the bridge and verify if the programming interface (in class code) is 01. How could this be done? Are there any other ways of achieving this? Thanks, DaveH Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107683

    - Generating keystrokes over USB Hi, I have a USB device, which you plug between a PC and a USB keyboard. The device normally works by responding to keystrokes from the keyboard, but what I want to do is to generate keystrokes programmatically from the PC. I know that OUT is an "unnatural" direction for keystrokes, but I hope to activate the device that way rather than by user interaction. Note that this is completely different from internal Windows events such as KEY_UP/DOWN/SendInput/etc. Does anyone know how to send a keystroke?

    - WDF driver on PIII dual processor Hi, I am working on a PCI driver, have tested the driver in different hardware combinations, it is observed that, test ouputs on WDF driver on PIII dual processor was different from others, here is summary. Test works in Uni processor & Quad core, but it fails in Dual processor PC, here it fails very few tests out of 15000 tests. Test generates around 60000 interrupts along with read & write DMA access, which also generate interrupts accordingly, based on read/write data, tests generates the interrupts. I am currently synchronizing all read, write, IOCTL requests, so in my idea, there wont be any chance that two requests would be running simultaneously on any core Just wanted to know, Any special care to be taken in Dual processor systems compared to muliticore PC's? Dual processor configuration: PIII, 550Hz 386MB RAM. I hope WDF works fine with Old processor configuration also.

    - Power Dispatch for XP driver in both platforms? Dear Sir: I have 1 driver for Serial-to-USB, it is WDM driver for XP driver. I put WDM-XP driver into Vista platform to run, and it will run in most parts of functions. I attached the modem to Serial-Port, use terminal to send "AT" command and it will return "OK". Aftern then, I run "S3" command to standby(not close terminal), and wake-up from S3. But after waking up from S3, I found I send "AT" command again, it can't return "OK". Below procedures, I try again by putting WDM-XP driver into XP platform to run, it will run successfully. I dump messages to show, when waking up from S3, the driver sent IoCallDriver to bus driver, but it would return error-code:0x103 and then set DTR&RTS, it will return IoCallDriver=0xC0000001, URB_STATUS(urb) = 0x80000800. //----------------------------------------------------------------------------------------------------------------------------------// urb = ExAllocatePool(NonPagedPool, sizeof(struct _URB_CONTROL_DESCRIPTOR_REQUEST)); if(urb) { UsbBuildVendorRequest(urb, URB_FUNCTION_VENDOR_DEVICE, (USHORT) sizeof(struct _URB_CONTROL_VENDOR_OR_CLASS_REQUEST), USBD_TRANSFER_DIRECTION_IN, 0, 0x01, // bRequest 0x8484, // wValue 0, // wIndex pvOutputBuffer, NULL, 1, // length NULL); ntStatus = SerialUSB_CallUSBD(DeviceObject, urb); *length = urb->UrbControlVendorClassRequest.TransferBufferLength; ExFreePool(urb); } else ntStatus = STATUS_NO_MEMORY; //----------------------------------------------------------------------------------------------------------------------------------// The working items in my PowerPnpDispatch are below: //----------------------------------------------------------------------------------------------------------------------------------// switch(pIrpStack->MinorFunction) { case IRP_MN_WAIT_WAKE: break; case IRP_MN_POWER_SEQUENCE: break; case IRP_MN_SET_POWER: switch (pIrpStack->Parameters.Power.Type) { case SystemPowerState: status = SerialUSB_ProcessSystemPower(PDevObj, PIrp); //initial HW, but fail break; case DevicePowerState: status = SerialUSB_ProcessDevicePower(PDevObj, PIrp); break; } return status; case IRP_MN_QUERY_POWER: SerialDump(SERPNPPOWER, ("USB2SER: Got IRP_MN_QUERY_POWER Irp \n")); if(pDevExt->PendingWakeIrp != NULL || pDevExt->SendWaitWake) { if( pIrpStack->Parameters.Power.Type == DevicePowerState && pIrpStack->Parameters.Power.State.DeviceState > pDevExt- >DeviceWake ) { status = PIrp->IoStatus.Status = STATUS_INVALID_DEVICE_STATE; PoStartNextPowerIrp(PIrp); SerialCompleteRequest(pDevExt, PIrp, IO_NO_INCREMENT); return status; } } PIrp->IoStatus.Status = STATUS_SUCCESS; status = STATUS_SUCCESS; PoStartNextPowerIrp(PIrp); IoSkipCurrentIrpStackLocation(PIrp); return SerialPoCallDriver(pDevExt, pLowerDevObj, PIrp); } // switch (pIrpStack->MinorFunction) PoStartNextPowerIrp(PIrp); IoSkipCurrentIrpStackLocation(PIrp); status = SerialPoCallDriver(pDevExt, pLowerDevObj, PIrp); if(pDevExt->SystemPowerState == PowerSystemWorking) { if(pDevExt->PowerState != PowerDeviceD0) SerialGotoPowerState(pDevExt->Pdo, pDevExt, PowerDeviceD0); if(pDevExt->bEverInPowerD3) { initial HW... } } //----------------------------------------------------------------------------------------------------------------------------------// How to modify this power procedures and let XP driver run successfully on XP and Vista Platforms?

    - IOCTL_NDIS_QUERY_GLOBAL_STATS Supported On Vista/Server 2008? Hi! Is this IOCTL still supported on NDIS 6.x platforms? In particular, can I still use this IOCTL on these platforms to plumb proprietary OIDs (i.e., OID value >= 0xFF000000) to a driver? I've heard the this IOCTL was in the process of being deprecated, and it seems that we have problems with it and proprietary OIDs on NDIS 6.x. Thanks!

    - EngAllocUserMem 64 bit driver, 32 bit client How to Do? Hi, I use EngAllocUserMem to large chunks of data between my display mirror driver and my client application. I'm a bit perplexed though as I have a 32 bit application that calls into the driver, the driver calls EngAllocUserMem (and gets a 64 bit pointer), then passes that value back to my 32 bit app. How can I thunk the address from the 64 bit driver (that created memory in my 32 bit process), back to my 32 bit process so I can access the memory? Is there an EngAllocUserMem32 function? Thanks, Brian Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107656

    - Print Driver Font Rotation Problem I am currently developing a rendering plug-in for Unidrv. When an application creates a font with the same orientation and escapement, I get an XFORM transformation that properly rotates the text. However, if the application specifies a a orientation and escapement that are different, the XFORM doesn't contain any shear and my printer output does not match the video display's output. In my OEMTextOut routine, I get an SO_ESC_NOT_ORIENT flag to tell me that they're different but I can't find out what the difference actually is. If I could get that delta, I could do a simple matrix operation to take the angle difference into account and get a proper display. Any input would be greatly appreciated!

    - Redistribution of Hotfix KB943198 Hi, I'm not sure if this is the proper place to ask this question, as it's not technical, but legal. But I've not found information about this elsewhere, so here goes........ I am involved in the development of a product that uses 'usbser.sys' and a large proportion of the target audience will be running XP. For users ruunning Windows XP SP2 a minimum of Hotfix KB943198 is required. This Hotfix is a free download, however once you follow the download link you then see that all users must pass WGA tests before being allowed to download this free update. My preference is to bundle the Hotfix into my program's installer and install it automatically (I've already constructed the Bootstrapper Package to achieve this). This is the easiest solution for the end user, but I suspect it will violate some legal requirement of MS......... So my question is: can I distribute Hotfix KB943198 as part of my Install in a way that doesn't break any MS legal requirements?

    - How can I reparse a device to a file in my minifilter driver in Hi all. How can I reparse a device to a file in my minifilter driver? I need to handle RAW disk access from my minifiler driver. But minifilter is a file system filter driver. It should be not received all read/write requests of raw device such as disk, IDE, SCSI, etc. So I reparse device to a file in PreCreate of my minifilter driver. When I can handle all read/write requests in the minifilter. It is working well in WinXP. But it should be BSOD in Vista anyway. And BugCheck is DRIVER_RETURNED_STATUS_REPARSE_FOR_VOLUME_OPEN. It means that I can't return reparse when open a volume. I have read the codes of WRK. It bug check at following place. // // No driver should return this status for a volume open. // If they do then we would skip the security check as override is true. // To catch that case we bugcheck here. // if (op->Override) { KeBugCheckEx(DRIVER_RETURNED_STATUS_REPARSE_FOR_VOLUME_OPEN, (ULONG_PTR)parseDeviceObject, (ULONG_PTR)deviceObject, (ULONG_PTR)CompleteName, (ULONG_PTR)ioStatus.Information ); Then Override is member of OPEN_PACKET. This is its comment. // // The following is used to indicate that an open of a device has been // performed and the access check for the device has already been done, // but because of a reparse, the I/O system has been called again for // the same device. Since the access check has already been made, the // state cannot handle being called again (access was already granted) // and it need not anyway since the check has already been made. // BOOLEAN Override; Why can I reparse it in WinXP? How can I do this in Vista? Thanks Doskey. Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107623

    - Windows 2008 IOCTL_SCSI_PASS_THROUGH to Inquiry Disk info. I have a program which works in Windows 2003 but failed in Windows 2008. This program uses IOCTL_SCSI_PASS_THROUGH to issue a SCSI Inquiry command to disks and enclosures. In Windows 2008 somehow it failed when the command is issued to a disk. I found an MS document at http://support.microsoft.com/kb/942448 it says Windows 2008 file system and storage stack restrict direct disk access. The article mentioned it restricts write and need to use LBA... But the disk I'm trying to access is a physical disk, and it does not have partition or volume on it, plus the SCSI command I issued is "Inquiry". It should not be considered as a write. But that IOCTL failed and the error code got with GetLastError is 1 (Invalid Function). I wonder is that by design? I also need to mention the same command issued to a SCSI Enclosure was successful. May someone there give me a hint? Thanks, Ken Tag: Uniqueness of DeviceName To NDIS ProtocolBindAdapter Tag: 107620

    - FltSendMessage - reply size does not jive with FilterReplyMessage I have a user-mode process communicating with a mini-filter using FltSendMessage. When the user-mode process sends down a reply to the filter it must include the FILTER_REPLY_HEADER per FilterReplyMessage docs. This is fine, no problem here. I'm stuffing a BOOLEAN just after the reply header to inform the filter to perform some action, so my reply is sizeof(FILTER_REPLY_HEADER) + sizeof(BOOLEAN). The problem is that FltSendMessage appears to require that the size of the FILTER_REPLY_HEADER be included in the "reply" buffer and size. When a buffer with sizeof(BOOLEAN) is specified with FltSendMessage it will *always* indicate that the space is too small for the reply data (STATUS_BUFFER_OVERFLOW). I would expect that FltSendMessage consumes the header as part of its transaction implementation and just passes FltSendMessage the contents past the header. I expect only to supply an reply space of "sizeof(ReplyUser) - sizeof(FILTER_REPLY_HEADER)", which in my cases is just a BOOLEAN. Structs look something like this: Reply { BOOLEAN do_something; } ReplyUser { FILTER_REPLY_HEADER h; Reply reply; } If I use a larger buffer in FltSendMessage for the reply (i.e. ReplyUser which includes the header), the reply value is placed at the base of the struct address. I cannot account for the behavior for FtlSendMessage with respect to FilterReplyMessage. It simply does not behave per docs and as the scanner filter example with the DDK would have you believe - my communication is quite similar to that example. What am I missing here?

Hi All,

I would like generate pseudo-unique 32-bit hash against the DeviceName
of ProtocolBindAdapter. I noticed that the GUID in the path persists
accross suprise removals, and I am guessing will persist across
reboots.

Can I rely on this?

Actually, I would prefer to take a hash of AdapterInstanceName of
NdisQueryAdapterInstanceName.

Is it guranteed to be unique amond devices installed?

Also, just out of curiosity, I would be interested in knowing the
typical string pattern for AdapterInstanceName generated for a
plurality of near-identical devices simultaneously installed, for
example, in the case of a quad-port gigabit Ethernet adapter.
