    - Please, someone at Microsoft could answare this issue!? Question is marked at the end of this mail!! I'm not able to avoid LanMan to process a request on \IPC$ I've my own redirector and I actually success the prefix claim to MUP: Return SUCCESS to CreateSrvCall Return SUCCESS to CreateVNetRoot My redirector is the first in NP order list. After this I should be the owner of \myserver\IPC$ so I espect to really fail an OPEN on such netroot without LANMAN to take the control. Application try to open \myserver\IPC$\srvsvc and \myserver\IPC$\wkssvc and I've tried to return: OBJECT_NOT_FOUND NOT_SUPPORTED NOT_IMPLEMENTED INVALID_HANDEL and so on... after every successfull call to my prefix claim functions LANMAN always try to open \myserver\IPC$ over the net, it holds win32 application for a long... LANMAN must get a timeout before returning... QUESTION ** I'd like to know if RDBSS addresses the \IPC$ OPEN to LANMAN without asking MUP to get the right provider!!!! Any of the STATUS code returned to CreateVNetRoot or Create successfull avoid LANMAN to keep control of the request!!!! Is it my fault or a RDBSS strange behaviour!?

    - USB Composite Device, Serial + Mass Storage, could not install ser Hi All, My current project need to implement a composite device which includes Serial and Mass Storage. and without any special driver on windows. I have made the Serial and Mass Storage work as a single function. To install serial, I just create inf file then windows can find and setup it correctly. But, after I create a new composite device, I can still install the serial port on windows by a new inf file but there is question mark (?) on my virtual serial port and it could not be opened. I check my firmware and all the USB request has been responsed. on windows XP, some things, during the copy file of usbser.sys, windows xp will reboot. The mass storage device can work without any problem. Are there anybody here who know if it is possible to install a composite device (CDC+Mass Storage) without and customer driver? (inf file is OK) Tag: What error does it mean Tag: 79391

    - Regarding SCSI miniport driver in 64-bit Hi All, I am trying to port a SCSI miniport driver for a virtual HBA that is working without any problem in 32-bit to 64-bit. When I install the HBA (by plugging it to a virtual bus which is created using toaster sample), the DriverEntry() is called followed by FindAdapter(). after that the driver is unloaded and the device manager gives the CM error code 10. (failed to start). The miniport driver is not using any resources. Following are the values I use for the HW_INITIALIZATION_DATA and PORT_CONFIGURATION_INFORMATION: HW_INITIALIZATION_DATA: 1. HwInterrupt(), HwDmaStarted() and HwAdapterState() are not used (set to NULL). Other functions are used. 2. NeedPhysicalAddresses is set to FALSE. 3. MapBuffers is set to TRUE. 4. NumberOfAccessRanges is set to 0. 5. TaggedQueuing is set to FALSE 6. MultipleRequestsPerLu is set to FALSE. 7. AutoRequestSense is set to FALSE. 8. ReceiveEvent is set to FALSE. 9. AdapterInterfaceType is set to Isa. One thing I noticed is that the ScsiPortInitialize() returns STATUS_SUCCESS.. In PORT_CONFIGURATION_INFORMATION, 1. InterruptMode is set to LevelSensitive. 2. CachesData is set to FALSE. 3. MaximumNumberOfTargets = 6 (just for testing) 4. BufferAccessScsiPortControlled = TRUE 5. ScatterGather = FALSE 6. MapBuffers = TRUE 7. NeedPhysicalAddresses = FALSE 8. TaggedQueuing = FALSE 9. MultipleRequestsPerLu = FALSE 10. AutoRequestSense = FALSE 11. Master = FALSE. Actually After FindAdapter(), the IRP_MN_REMOVE_DEVICE is called for the adapter in the bus driver which unloads the driver. So, there should be some problem in FindAdapter() that causes this. But same code works fine in 32-bit without any problem. When I examined the event log, I got following error: Driver detected an internal error in its data structures for \Device\Scsi\MyDrv1.

    - Device manager Hi! I've been given a legacy "software-only" driver that provides virtual serial ports. The problem is that the driver doesn't support pnp, so the serial ports doesn't show up in the device manager (only FDOs there, right?). What would be the simplest way to make the device manager aware of the ports? I've tried making the driver pnp-compatible, but that is starting to seem like a dead-end. First, I made a bus driver that hosted the virtual serial ports. Worked fine except for the fact that windows refused to automatically select the drivers, so when the user installed a serial port (which can be done at any time) he/she needed to locate the drivers. Not good. I used SetupCopyOEMInfo to make windows aware of the inf-file - my theory is that windows won't automatically select a driver that is not signed. I also tried doing a user-mode installation of the port, using the code from Walter Oney's Fastinst program. That works fine as long as only one port is installed. If several ports are installed, each new installation causes all existing ports to be reinstalled by UpdateDriverForPlugAndPlayDevices. Again, not good. Any ideas? Thanks in advance, Nille Tag: What error does it mean Tag: 79370

    - Limit on data that can be sent through ExtEscape I am working on a unidrv printer driver. In order to provide some custom functionality, I need to pass some data to the graphics dll (spooler context) from the ui dll (application context). I am using ExtEscape to do this. This works fine except that I do not receive the full data in some cases. I believe this happens when the data size is too large. Is there any limit on the size of the data that can be transferred through ExtEscape. Thanks in advance. Tag: What error does it mean Tag: 79369

    - DIFx bus driver install Hi, I would like to use DIFx to install a bus driver, this bus driver is very simular to the one in toaster WDK sample. Everything seems fine but looking at the log file: DIFXAPP: INFO: No matching devices found in INF "C:\WINDOWS\system32\DRVSTORE\...drv.inf" on the Machine. DIFXAPP: INFO: No drivers installed. No devices found that match driver(s) contained in 'C:\WINDOWS\system32\DRVSTORE\...drv.inf". DIFXAPP: SUCCESS:Installation completed with code 0xE000020B. DIFXAPP: INFO: RETURN: DriverPackageInstallW (0xE000020B) DIFXAPP: The device(s) for which the driver is being installed has not been plugged into the computer. It turns out that the bus driver is pre-installed but not started. If I want to install it manually, I need to indicate that the hardware is already connected in the "Add/Remove hardware" feature. I guess that here is the issue. How can I tell DIFx to start the bus driver after it installed it ? I did not find any sample for that, the toaster one only focuses at a toaster device DIFx not the busd driver one. Is this a DIFx limitation ? Thank you for helping me, Jean Tag: What error does it mean Tag: 79365

    - Bsod - filter manager Hi, I'm trying to determine why my machine crash during startup, and by doing an analyze on the stack dump, it seems to point to filter manager. However, I think there might be something else, but I'm unsure how to proceed. Surely it must be some dodgy drivers being loaded but how do I find out?

    - NDIS problem indicating from MiniportSendPackets Hi I have written an NDIS IM driver that do some filtering of packets. This is basically what is does: * In MiniportSendPackets - save off a copy of a TCP SYN packet and notify a user mode application about this using a shared event object. The original packet is discarded (not send further down with NdisSend). * The user mode application tells the driver how to rewrite the saved SYN packet which in the same call allocates a new NDIS_PACKET and indicate this packet up with NdisMIndicateReceivePacket. * The packet arrives to a user mode application listening on the destination address of the rewritten packet. This accepts the connection which sends a SYN/ACK that I catch in MiniportSendPackets. I here make a copy of the SYN/ACK and modifies the copy once again by changing source and destination ip/port, recalculate the checksum and then indicate this copy up with NdisMIndicateReceivePacket. The problem is that this copy never seems to get through the tcpip.sys layer - that is not going to the socket matching the source/destination ip/port of the packet. I can't understand why this works in the first step but not in the second. The only difference between the two are that in the first case it is (it might be) running at a different IRQL but this should not make any difference. Can there be a problem that the SYN/ACK copy is being indicated before the original SYN/ACK has been completed? This doesn't sound very likely since they have nothing with eachother to do (atleast not that the upper layer knows of). I have tried both copying the original OOB data and not doing this but without any difference in behaviour. The same with setting packet flags. I don't use NDIS_SET_ORIGINAL_PACKET since the two packets should not be linked together. I use the same handle for the MiniportAdapterHandle for the two indications and I allocate the packets from the same pool (same PoolHandle). I do the same procedure for packets coming off the wire which works great so I only have problems with the packets that are being looped back without going out on the LAN. The difference between the two are that in the case where packets should be looped back I need to indicate all packets from the MiniportSendPackets and in the "normal" case from the LAN I only indicate them from ProtocolReceive/ProtocolReceivePacket and filter outgoing packets in MiniportSendPackets with NdisSend. I've tried to look at the TDI layer for the packet but it doesn't show up there so it must be lost in between the upper NDIS and lower TDI which I guess is the tcpip.sys driver. Is there a way of debugging or logging what is happening at the upper NDIS layer or in tcpip.sys? I can't use ethereal since this doesn't work well with IM drivers and communication on the same machine. Everything would probably be solved if I could guarantee that a packet which has the same destination MAC-address as the sending machine would always be looped back by the underlying driver so that I could process the packet normally in the ProtocolReceive/ProtocolReceivePacket instead. Is there a way of forcing an underlying layer to do loopback? I also must be able to tell that the packet is originating from the local machine (to avoid spoofing). Any suggestions on why I can't get this to work or some tips on how to figure out what is causing the problem? Magnus Tag: What error does it mean Tag: 79355

    - Efficient serial port access We have a kernel-mode DLL that needs to detect a signal event (CTS) taking place in a serial port. The 10us wide signal comes at exact 1000ms intervals from the accurate external clock. By comparing the performance counter values at the moment of event detection, we have noticed that there is a fluctuating delay in detecting the CTS event. The 0.25ms delay stepwise accumulates for 3-7 successive events (up to even 1,6 ms) and then resets by itself. This kind of delay is too much for our time critical solution and invalidates the benefits of the accurate GPS clock used. Below, I have included the code for listening the serial port event. Is anyone able to provide a faster way of detecting the CTS pulse? The listening takes place in its own thread and its priority is the highest possible. Does the port's read timeout have an effect on detection delay? Thanks Ali //***************************************************************************** // WaitForCTS // Waits for the CTS event to take place in a serial port. // aDeviceObject - Port device object. // Returns the status code. //***************************************************************************** NTSTATUS WaitForCTS( IN PDEVICE_OBJECT aDeviceObject ) { NTSTATUS status; PIRP irp; KEVENT event; IO_STATUS_BLOCK io_status; ULONG events_occurred = SERIAL_EV_CTS; KeInitializeEvent( &event, NotificationEvent, FALSE ); // set up an IRP for waiting events irp = IoBuildDeviceIoControlRequest( IOCTL_SERIAL_WAIT_ON_MASK, aDeviceObject, NULL, 0, &events_occurred, sizeof( ULONG ), FALSE, &event, &io_status ); // send the IRP to the driver status = IoCallDriver( aDeviceObject, irp ); if ( status == STATUS_PENDING ) { // wait for the completion status = KeWaitForSingleObject( &event, Executive, KernelMode, FALSE, NULL ); } if ( status != STATUS_SUCCESS ) { if ( status != STATUS_TIMEOUT ) { DbgPrint( "Error %#X\n", status ); } else { KdPrint(( "Timeout\n" )); } return status; } return io_status.Status; } Tag: What error does it mean Tag: 79350

    - How to safely write EA to a file at file system filter driver level Hi folks, I have a file system filter driver that constantly monitor file changes. When I detect a file change, I would write EA (Extended Attribute) to that file. There doesn't seem to exist a documented kernel API to do it. So by reverse engineering, I created a way to do it. By reverse engineering, I mean I interceptd the ZwSetEaFile call, and looked at how irp was built, and mimic the irp operation. This sometimes caused problem. The symptom IS MFT corruption error. I figure may be I run into some synchronization issue because of not holding the internal lock used by ntfs. Does anybody have any suggestion on how to fix this problem? Thanks.

    - Processor Affinity and friends Dear All Let's take a dual-processor machine for example: If I set the processor affinity in IoConnectInterrupt to only one CPU, then the ISR and all code synchronised with it will run on the specified CPU. Could somebody confirm if this is right as well, please : - If an application talks to my driver directly (no filter drivers involved), and that application is running on both CPUs, then all code in the driver executed by the calling thread of the application will run on the same CPU as the application thread was running on. I.e. there is no CPU switching performed when calling into the kernel. - What CPU are DPCs executed on? As interrupt affinity does not apply to DPCs, I would think that the DPC could be executed on any processor. - What CPU are Power Management and PnP Request carried out on? As per my understanding, this is executed on any of the two processors, depending on the calling (Operating System) thread. Following on from this: - You can tie entire applications to run on only one processor by using 'Imagecfg.exe'. Is there a way of forcing all driver code to be executed on only one processor? I am sure the answer is NO, but I want to be mega-sure! :-) Thanks Christian Tag: What error does it mean Tag: 79321

    - Really need help on NAMED_PIPE support... Hi All, just few words: Simple mini-rdr registered as UNC Provider with MUP working as well! Now the the issue: Just consider wmplayer - but it happens with most applications. Opening files with wmplayer, application start reading and playing data with a normal delay of 2 seconds but user interface stays in hold for a long. After 30/40 seconds control goes back to user and everything work as well... It happens because applications start NAMED_PIPE requestes to the redirectors and my mini-rdr does not provide support for such service, in this way the requestes are sent to others rdrs which start network requestes - think should be the LANMAN... During MUP prefix claim in CreateVNetRoot my rdr returns STATUS_NOT_SUPPORTED ad I think this is the reason for which MUP ask other provider to resolve the name... I actually receive this prefix claim many times... I'd like to inform MUP that I'm the provider for such prefix but that I do not provide support for PIPE!! The FullPath is: \\myserver\IPC$ ...and I do not want to support NAMED_PIPE service. I've also tried to return STATUS_SUCCES in CreateVNetRoot and fail the Create with STATUS_INVALID_HANDLE or STATUS_NOT_IMPLEMENTED... Removing all other providers from registry OrderList - my rdr is the first one - everything work fine... I really need help Ale Tag: What error does it mean Tag: 79294

    - UpdateDriverForPlugAndPlayDevices Hi! I have a user-mode setup program that installs a virtual serial port hosted by our serial port driver (call it vserial.sys). The user should be able to install and uninstall these port as he/she pleases, each port being hosted by vserial.sys. The problem: UpdateDriverForPlugAndPlayDevices reinstalls existing ports when invoked. This is no good for several reasons - it would break existing connections to the port, the user gets the annoying "driver not signed" message first once, then twice etc when installing a single port. Another problem with the installation is that when the second port is being installed, the PnP manager (or someone) refuses to add the device without the user restarting the computer, probably due to the fact that the driver is already loaded into memory. I simply want to be able to install/uninstall one port at a time without restarting the computer. An installation of one port cannot cause another port to be reinstalled. How can I accomplish this? Btw, this is a legacy driver, and the only thing I wish to do is to make the virtual ports visible in the device manager, as simple as possible. The only way I've been able to do this is by implementing PnP support in the driver and doing a proper installation. If there's a simpler way (e.g. by doing some user-mode magic) I would be very happy to know about it... Thanks in advance, Nille Tag: What error does it mean Tag: 79285

    - MmGetsystemAddressForMdlSafe(...,HighPagePriority) returns NULL I have following problem: In user space is successfuly created buffer and this is passed with DeviceIoControl to IM driver. Driver is running under verifier in Windows with checked version of nt and hal. There often occures that MmGetSystemAddressForMdlSafe(...,HighPagePriority) returns NULL. It is mainly under memory stress and higher CPU load, but also several minutes after it when CPU is low utilized and there is sufficient amount of available memory. There is tried to map memory with size from 1kb to 8kb. I tried PerfMon in this state and I saw that free PTE is about 2400. What can be reason of returning NULL ?

    - No Events Visible in WIA Microdriver I'm currently writing a WIA microdriver for a simple scanner that has a button. I've triple-checked everything and I know that the event GUIDs I return in the CMD_GETCAPABILITIES command are the same as the ones in the INF. I've also checked the registry and can see the events listed in there (HKLM/System/CurrentControlSet/...). In my INF I set Capabilities=0x31 (which should eb the correct value). Additionally, I do get an event handle in CMD_GET_INTERRUPTEVENT that I can then set when I receive a button event. However, when I open the properties for my scanner (from the control panel) I cannot see the events tab. This means that my button presses don't get recognized by Windows. I'm using Windows XP with the DDK 3790. Everything else (including the ability to scan appears to be working correctly). I'm hoping that someone out there has an idea why the events tab would not show up. Thanks in advance. --Mike Tag: What error does it mean Tag: 79270

To install mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware.

    - ZwOpenFile issue I have a filter driver that filters the UDF. When the UDF mounts the filter looks for certain files on the DVD to verify if it is something that I want to "filter". I use ZwOpenFile in the SetupCallback routine. This works fine except for one problem. If the last disc to be in the drive was one that I was filtering and I then eject the disc and unload/load the filter. Eventhough the disc is no longer in the drive I get a mount request. This would be OK except for the fact that my ZwOpenFile never returns. It is OK if there is ANY disc in the drive (one that I filter or not) but the lack of a disc seems to cause an issue. I think this is because of the caching the windows does. Is there a call that I can make so that windows can flush the cache so that it will recognize that there isn't a disc in the drive to mount? Is there an option to ZwOpenFile or InitializeObjectAttributes that I should set differently? I have tried FILE_SYNCHRONOUS_IO_ALERT. Here is my ZwOpenFile InitializeObjectAttributes( &ObjectAttributes, fileName, OBJ_CASE_INSENSITIVE|OBJ_KERNEL_HANDLE, NULL, NULL); ntStatus = ZwOpenFile( FileHandle, GENERIC_READ|SYNCHRONIZE, &ObjectAttributes, &IoStatusBlock, 0, FILE_NON_DIRECTORY_FILE|FILE_SYNCHRONOUS_IO_NONALERT); Thanks! -- Still trying to build a perpetual motion machine Tag: What error does it mean Tag: 79255

    - NdisMallocatemapregisters NdisMallocatemapregisters allocate map registers and should be allocated called before allocating shared memory. NdisMallocatesharedmemory returns both virtual address(logical address) and physical memory. As far as I have understood map registers are used to map logical address to the corresponding physical address. But in any OS there will be page tables to map a virtual address to a physical address. I think that both logical address and virtual address are same. Correct me, if I am wrong. My question is why this map registers are used exactly? Thanks in advance hiremath_vi Tag: What error does it mean Tag: 79249

    - Customize return code of SCardControl for Smart Card Reader driver In winerror.h, error code define format: // +---+-+-+-----------------------+-------------------------------+ // |Sev|C|R| Facility | Code | // +---+-+-+-----------------------+-------------------------------+ We set the C flag in the error codes. If Sev set to 10 warning or 11 error, application could get these kinds of error codes. If Sev set to 01 Informational or 00 Success, SCardControl always got SCARD_S_SUCCESS as return code. I think PC/SC library changes it. How could let PC/SC not do that ? Another problem is when Sev set to 10 or 11, no data could be got from SCardControl, PC/SC ignor all outdata in this case, how could I let PC/SC not do that ?? Thank you in advance !!

    - What's input/output buffer format of IOCTL_IDE_PASS_THROUGH ? My usb storage driver is failed in Media Status Notification test of HCT. I found that HCT issues IOCTL_IDE_PASS_THROUGH command to driver's ioctl dispatch. Since my driver didn't support this ioctl code, the test is failed. It seems that HCT tried to send ATA/ATAPI identify command and get failed status. Where can I find the information about IOCTL_IDE_PASS_THROUGH?

    - CPU load balancing I have two 64 Opterons processors in machine, and I run on it 32 bit Windows XP/2003 temporary. When my IM driver does packet filtering on higher speeds (100Mbit and more) in Task manager I see that CPU load is never divided between both processors fifty-fifty. As average CPU load grows - one processor always grows to 100% and second is about 20%. Is this normal behavior ? Is possible to set manually somewhere in registry more equal CPU load ?

    - How is possible that NDIS_PACKET->Head->MappedSystemVa is pageable I met bug: DRIVER_IRQL_NOT_LESS_OR_EQUAL, Bug occurred inside of: NdisMIndicateReceivePacket(...,myPacket, 1); called from my driver. Amazing is that address of memory referenced is inside of NDIS_PACKET: MyPacket->Head->MappedSystemVa. I see in memory in debugger that MappedSystemVa is not displayable ant it show error ERROR_READ_FAULT, so it is probably paged. I met this bug in system with debug versions of kernel,hal and ndis.sys and on system running under memory stress with driver verifier turned on my driver and ndis.sys. MyPacket was allocated with NdisDprAllocatePacket() and buffers are created by copying from original packet with help of NdisCopyBuffer(). How can be possible that packet created by such way has paged Head->MappedSystemVa ? What can I to do in my code to avoid of this ? Peter Tag: What error does it mean Tag: 79224

    - Missing ieee1394 bus reset on sp2 Hi: I have a program talking to devices on ieee1394 bus via virtual driver. The driver registers bus reset notification routine to update active device list. I found that the program/driver running on sp2 do not get bus reset notification when the last device is being disconnected from the bus. When there are still other devices on the bus besides local host all resets from connect/disconnect do produce notifications. This same program/driver pair on sp1 does not miss any bus reset notifications. Is anyone familiar with this problem? Given this problem (and other, like 1394b) is it possible to downgrade the 1394 stack on sp2 to sp1? Thanks. Vladimir Tag: What error does it mean Tag: 79201
