Pending PCPropertyRequest
Hi,
I'm trying to pend a PCPROPERTY_REQUEST and complete it at a later stage. My
code snippet is below. What I observed is that the PropertyRequest seem to
get completed in the end even though I return STATUS_PENDING. From DDK, this
seems to be all that is needed to pend the request. I need to pend the
request as I cannot complete it now. Can anyone advise me on this?
NTSTATUS
PropertyHandler_MyHandle
(
IN PPCPROPERTY_REQUEST PropertyRequest
)
{
ASSERT(PropertyRequest);
NTSTATUS ntStatus = STATUS_INVALID_PARAMETER;
if (PropertyRequest->Verb & KSPROPERTY_TYPE_GET)
{
switch (PropertyRequest->PropertyItem->Id)
{
case TO_PEND_CASE:
{
g_pPropertyRequest = PropertyRequest;
ntStatus = STATUS_PENDING;
break;
}
......
......
}
}
return ntStatus;
}
NTSTATUS
DeferredCompleteRequest(void)
{
....
PcCompletePendingPropertyRequest(g_pPropertyRequest);
...
}
Thanks,

Point-to-point tunnel interface
I've been looking at how to develop a tunnel interface, similar to what we
find in Linux/*BSD environments, tun(4). This interface is seen as a
point-to-point interface, and can be read/write into to move packets in and
out of the kernel. This is really useful to create new tunnel encapsulation
methods (IPv4-over-IPv4, IPv4-over-UDP/v4, IPv6-over-*, etc.)
On Windows, information is available to create a NDIS miniport driver, but
this approach would make the driver "ethernet-like" (broadcast interface)
instead of p2p. Consequence is one has to handle things like ARP and such to
make that interface appear as p2p. I believe the same applies to an IM
driver approach.
It appears like the approach should be a something like a NDISWAN driver,
where this interface is seen be the operating system as a "Tunnel Adapter",
but without the L2 framing (PPP, etc.). Is that approach possible? Is there
any pointer for documentation on doing this kind of development?
Thanks.

Sending Async Irp with IOCTL_HID_GET_FEATURE
Hi,
I am creating an Async Irp in firefly with control code
IOCTL_HID_GET_FEATURE to get the feature report. I am using IoAllocateIrp()
and IoAllocateMdl() for the irp creation. The expected behavior is this irp
will get status_pending in return and the real hardware change will trigger
the completion routine gets call. The custom HIDMini driver now calls
IoMarkIrpPending and return status_pending for this irp. But the firefly
filter halts at the call of IoCallDriver().
PIRP irp = IoAllocateIrp(NextLowerDriver->StackSize + 1, FALSE);
irpSp = IoGetNextIrpStackLocation(irp);
irpSp->MajorFunction = IRP_MJ_DEVICE_CONTROL;
irpSp->Parameters.DeviceIoControl.IoControlCode = IOCTL_HID_GET_FEATURE;
irpSp->Parameters.DeviceIoControl.OutputBufferLength =
FeatureReportLength;
irpSp->FileObject = fileObject;
irp->MdlAddress = IoAllocateMdl( report,
FeatureReportLength,
FALSE,
FALSE,
(PIRP)NULL );
...
...
IoSetCompletionRoutine(irp,
GetFeatureCompletionRoutine,
Context,
TRUE,
TRUE,
TRUE);
status1 = IoCallDriver(NextLowerDriver, irp); <--- this
call never returns
I wonder since the mini driver Marks the irp pending and return status
pending, why the GetFeatureCompletionRoutine never gets triggered and the
"status1" code never gets assigned any value. Is it because the Hid class
handle IOCTL_HID_GET_FEATURE synchronously?? So the irp will not come back
until it is completed? In that case, what method should I use to send a irp
down to get the hardware event?
I am also considering to assess the "Extra Information" and "Raw button"
field in the MOUSE_INPUT_DATA struct, as long as the custom mini driver can
fill in these field. But I am not sure how to send back these info in the
mini driver. Please help.
Thanks in advance.

To lock, or not to lock, pages...
Ok, I inherited a basic Windows USB driver that handles pushing data across a
couple of bulk pipes. This driver works fine under Win2K, but eventually
crashes XP/SP2 with a page fault error...
Now, this driver takes a large user buffer and chops it up into nice
USB-able sized blocks. It allocates a MDL and then re-uses it over and over
again, freeing it once the entire transfer has been shoved across the bulk
pipe. Never does it try to MmProbeAndLockPages(), which I found odd.. but it
works under Win2K..
So my question is: should I put in MmProbeAndLockPages() for the user
buffer? And if so, before or after IoBuildPartialMdl() (I think before since
the user buffer needs to be resident, right)?
I'm somewhat clueless, so apologies if this is a dim question. I'm reading
all the docs I can get my hands on! Tag: Vista SCSI driver Tag: 69069

Win98 Keyboard driver for exclusive control of PS/2 keyboards
Greetings.
Is it possible to write a Win98 keyboard driver that is dedicated only
to PS/2 keyboards?
The reason is that I've toasted the built-in keyboard of my notebook
(Microflex, FlexNote 595). An external keyboard has been plugged to the
PS/2 port, but unfortunately, the internal one still refuses to
relinquish its grip with the system.
As both keyboards share IRQ 1, wonder if there is any chance of
customizing/re-writing a keyboard driver so that it's able to analyse
the source of the interrupt and ignore anything except from the PS/2
port.
Being a newbie to win32 system programming, hope to get some ideas on
this one before downloading the Win98 DDK.
Thanks. Tag: Vista SCSI driver Tag: 69053

1394 Virtual Devices And Writing To Host Config ROM
Hello All,
I can successfully add a Unit Directory to the my first pc's 1394 Host
Config ROM to
represent my virtual device. And I can verify that the host's config ROM
contains my new unit directory and text leaf by using my FireSpy tool.
My unit directory looks just like the "NIC1394" unit directory which I guess
is added by windows at boot time.
When I connect a second pc containing a 1394 host controller,
the plug and play manager of the second pc does "know" that there is
"new hardware" listed in the first pc's config rom and it trys to find a
driver
for the new device.
However, the new hardware found dialog on the second pc always displays
"Unknown" instead of the device string information I wrote to the Text Leaf
in
the first pc's config ROM.
Is there some magic to adding a Unit Directory to a 1394 host config ROM?
There is very little documentation on how to write to the host config rom
to emulate hardware. I think I'm doing everything correctly.
Thanks in advance for any help,

Add local port
Hello NG,
I've played around with XcvData in order to create a new local port
programatically. I'm able to create a new "Standard TCP/IP" port but thats
not what I want. I use the following code snipnet,
HANDLE hPrinterTemp;

prDefaultsTemp.DesiredAccess = SERVER_ACCESS_ADMINISTER;
prDefaultsTemp.pDatatype = NULL;
prDefaultsTemp.pDevMode = NULL;
if(OpenPrinter(L",XcvMonitor Local Port", &hPrinterTemp, &prDefaultsTemp)){
if(XcvData( hPrinterTemp, L"AddPort",

}else{
dwError = GetLastError();
}
}
I can successfully open the handle to the "Local Port" monitor. But with
"XcvData" I always get an Error 87 "Invalid parameter". Does anybody know
how to add a local port through "XcvData" ??

Questions about driver install using DIFx
I'm trying to install a network filter driver using DIFx2.0 and got two
questions:
1. DIFx2.0's document for DPInst says that the DriverPackageType has to
be either ClassFilter or PlugAndPlay. Does this mean they don't support
drivers of other types anymore? DIFx1.1 used to support more than the
two types. Why the upgraded DIFx supports less types?
2. Our driver has two inf files, say a.inf and b.inf. I used "Network"
as their driver type anyway and put them under the same directory of
the DPinst.exe. After installation, the Device manager shows two copies
of the network filter, where there should be one item only. The a.inf
lists b.inf under the [SourceDisksFiles] section. Also, DIFx says that
any inf files in the DPInst.exe's directory will be parsed. I wonder if
the b.inf file got picked up twice?
Thanks!

Question on 'Safely Remove Hardware' for Flash card (usb mass storage)
Hi --
I have a program running that saves files on a flash card. It processes
the WM_DEVICECHANGE message for DBT_DEVICEQUERYREMOVE and closes its open
files and returns. But, when I use the 'Safely Remove Hardware' icon, I get
the system message that the device can't be removed - try again later. This
message happens before I return from the WM_DEVICECHANGE notification. It
appears that the system only gives me a very short window in which to get
the files closed and then complains.
So my question is --- Is there any way that I specify a wait interval
for the device so that I can get the files closed and the device removed?

Device Driver - Direct Access to Endpoint 0

functionality (like beep buzzer, blink error LED)
Is it possible for the functional driver to directly access endpoint 0? I

Question about using MmGetSystemAddressForMdlSafe or MmGetSystemAddressForMdl

As I know, calling the MmGetSystemAddressForMdlSafe or

So my question is, do we need to call MmUnmapLockedPages for un-map the
page which mapped by MmGetSystemAddressForMdlSafe or
MmGetSystemAddressForMdl, if it is no longer need. And, how to check it is
mapped or not?

website, when unmap the pages.

64bit issues
After years of procrastination I finally upgraded my development
environment and test lab to support 64bit builds and test systems.
That's the good news. The bad news is that the 3790 ddk x64 compiler
is failing on me with rather hideous frequency.
Here are a pair of typical examples:
sys\nullfdo\nullfdo.cpp(1) : error <func:#12> Compiler error
(assertion): file f:\vs70builds\2232\vc\Compiler\Utc\src\P2\p2symtab.c
line 5112
sys\nullfdo\nullfdo.cpp(1) : error <func:#12> Compiler error (internal):
Access Violation Fault (instruction at "0x1083B042" read memory at
"0x00000030")
The development system is a dell xeon workstation - and it is not
randomly croaking on other activities, so I more or less have to
conclude that there are issues with the x64 cross compilation. Anybody
else having similar problems? Is this a known bug? I googled this and
indeed there are other people reporting similar assertion failures. Here
is a response from Ms on this very issue:
"You are using a pretty old compiler. Are you on Betaplace for the AMD64
PSDK beta? If so, go there to get the latest one. If not, email me and
I'll get you added to the program.
Thanks,
Kang Su Gatlin
Visual C++ Program Manager"
http://www.mcse.ms/archive108-2004-6-754977.html
Hmm... pretty old compiler? This guy was using the 3790 DDK. So I looked
at my build configuration and lo and behold, for everything except WDF
drivers I am using the 3790 DDK. It seems that the 3790 DDK doesn't
actually reliably support x64 builds.
Before you say "well just go use the 3790.1830 ddk", I thought the same
thing. However there is a reason why I'm stuck on 3790: the last
released IFS kit is 3790 and I need bits and pieces from that to build
all of the stuff I build. So I am sort of stuck. The WDK has all of the
IFS bits, but it is beta. The 3790 ddk is unacceptable.
What the heck are other people doing?

Reprise: Pended IOCtrl + LoadLibrary == Deadlock?
Greetings again,
Having finally bitten the bullet and installed windbg to supplement my
SoftIce, I have a slightly clearer picture of a deadlock problem I have
been struggling with for some time now (the original post from August 24
is included below). A brief description of the trouble is that my main
app thread locks on a LoadLibrary after a separate thread blocks on a
pended IOCtrl. If I comment out _only_ the IOCtrl call, the main thread
runs as expected (although it is difficult to confirm exclusive
causality in this case as there are several other threads running around
which plausibly may be interacting).
Per windbg, the call stack of the main thread is:

I was not completely surprised to see IopAcquireFileObjectLock in the
stack as this seems to be a common pitfall. But unfortunately, it does
not seem to be blocking on a lock in the !lock sense of the word and as
such I can not see who is causing the holdup. In fact, both windbg and
SoftIce claim that the thread is blocking on an event. On a whim, I
dumped the memory at the first parameter to IopAcquireFileObjectLock,
0x84af8610:
|

84af8610 00000001 00000001 00000000 00040001 00000000 84555968 84555968

I recognized this memory straight away from previous dumps of the KEVENT
that the thread is blocking on. It is very recognizable because there
are two KEVENT structures in a row. The arrow above points to the first
one which is this KEVENT the main thread is blocking on, 0x84af861C.
This makes sense from as the waiting list pointers, 0x84555968, indicate
one element in the list and one that is very close to the thread in
question, 0x845558f8 (and indeed SoftIce tells me my thread is the only
wait thread when I query the event). I am assuming that this first
parameter to IopAcquireFileObjectLock is some subcomponent of a file
object which contains a number of different events.
Unfortunately, none of this information helps me. I can find no
relation between this thread and the thread that seems to be related to
the problem. The !locks command sounded great until I realized it only
works on, well, locks. Everything is blocking on events and a such I am
not sure how to determine what the lock-up is. I am kind of assuming
that two threads are waiting for events that the other is supposed to
signal. But it is not at all clear to me how I would determine that
this is the case.
Does anyone have a suggestion how I would best proceed? I am quite
confused as to why the LoadLibrary would block on that particular handle
because the dll is not in memory prior to the LoadLib call. Thus it
should not be possible for someone else to be using the file handle (or
object) in a way that would cause a lock. Furthermore, the other thread
is blocking on an IOCTRL to a completely separate module (obviously).
It occurs to me that the parameters being fed to KeWaitForSingleObject
(00000001 00000000 ffffff01 as per Args to Child above) look
suspicious - perhaps a wild pointer. Are those the real parameters or
is KeWaitForSingleObject using a calling convention that makes this
analysis invalid? From my read of things, the first parameter,
0x00000001, should be the object to wait on.
Or is it possible that there is some process wide lock that is being
held for some reason rather than a lock at a file object level?
At any rate, any help would be much appreciated as I am more or less
stumped at the moment.
Best regards,
Tom Udale

Original Post
====================================
Greetings,
I have been struggling for several days now with a deadlock. This is a
multithreaded app running on XP communicating with a software only NT
style driver. The basic symptom is the app opens two handles to the
driver. The main process thread uses one handle for "fast" IOCtrls
(meaning from the apps standpoint it does not care how long the driver
takes and assumes that time will be short) and the other handle is used
in a secondary thread that makes "blocking" calls (meaning the app
assumes that the driver will take a long time to satisfy the request -
which of course is true).
In this case, the secondary thread does indeed block for a very long
time as it is being used to set up a "call back" from the driver. When
the driver wants the usermode app to execute some command, it completes
this ioctrl which then makes the thread run and the command be executed.
The trouble I am having is that after the ioctrl is pended, the main app
thread does a LoadLibrary, which hangs for ever. If I comment out only
the IOCtrl (leaving the secondary thread creation and general operation
intact) the LoadLib is happy. Unfortunatly there are a number of other
threads running around to complicate things, and of course the
possibility that the driver is silently hacking something always exists,
but from my current analysis is seems pretty likely that this one thread
blocking on an ioctrl is the culprit. My "analysis" in this case being
the obervation that commenting in and out the ioctrl call nicely turns
on and off the error.
Is there any fundemental reason that I cannot block in an ioctrl and
then expect a loadlib to work? I know for example that there is a "Load
Lock" somewhere in LoadLib that you can get into trouble with (by for
example loading other libs within the libmain of another). Is that used
by IoCtrls as well? (BTW, softice tells me that the call stack of the
main thread is in the CRT io_init of the dll that is being loaded. The
last few functions are
NtQueryVolumeInformationFile,NtWriteFile,KiUnexpectedInterrupt).
Or is this more likely some subtle stupidity on my part? If this simply
cannot be done, I will have to redesign part of the app. Otherwise, I
will keep looking for my stupidity.
Best regards,

ATA driver model in Vista
Hello,
Windows Vista DDK document two IDE drivers. ATA miniport driver and
controller minidriver. The miniport driver has both controller and channel
interface while minidriver has some minimal controller interface with access
to PCI config space. I don't have a sample code of miniport driver.
How does these two drivers work together ? Is it allowed for two drivers to
access single device ?
Thanks for any help

dialog box in printer driver
I am working on a virtual printer driver based off of the bitmap sample. I
want to popup a dialog box so that the user can choose a file location (i.e.
save as). What is the best way to go about this? I have tried
GetSaveFileName but that requires inclusion of windows.h which is a no-no
according to comments in winddi.h. Linking MFC does not seem wise either.
Any ideas? Tag: Vista SCSI driver Tag: 68861

EngWritePrinter error: ERROR_INVALID_HANDLE
Hello,
please help me out with one problem in EngWritePrinter, when i was trying to

Task:
1. My task is to customize the Document PropertySheet i.e. on clicking the
print preferences button i have to show my own customize PropertySheet rather
than the default one (i.e. "Layout","Paper/Quality").
2. My dreanms also comes true if i am able to Rename those "Layout"&
"Paper/Quality" tabs.
Can u please tell how can i do that ? Please give the solutions of either of
my problems ?

Changing spool settings for generic / Text only driver.
Hi there.
I'm writing a program intended to run at a windows 2k3 server, to update
printersettings for the generic / Text only driver for each session the
driver is imported.
I've succeeded to make most of the changes by writing/changing different
keys in the registry, however i'm having trouble finding out where the "Print
directly to printer" (Don't use print Queue) setting is set.
Does anyone know where this setting is, or is there std. librarys for
changing printersettings to find ? Tag: Vista SCSI driver Tag: 68794

System Mouse Button State
Is it possible to retrieve the current state of the system mouse button
(i.e., to find out which buttons are currently pressed or released) without
setting hooks and having to track all mouse events? Ideally, I am looking

button state rather than cursor position. A kernel-mode function would be
even better, but I don't believe it's possible.
