Wow... in reference to the Code Project article: http://www.codeproject.com/KB/system/driverdev2.aspx Like just about every article on kernel-mode programming on Code Project, this is a particularly TERRIBLE example.

SDV will work on things it does not explicitly have rules for, but the problem is that it does not have enough context to do that much useful. The power of SDV is its ability to understand the relationships between paths through the driver, and until they set up an environment for mini-filters you are not getting that. -- Don Burn (MVP, Windows DKD) Windows Filesystem and Driver Consulting Website: http://www.windrvr.com Blog:...

Right - so there is no good answer for XP64 and W2K364. Luckily neither of these are actually mainstream releases, so I would suggest the following for them: punt. Either that or go to blackhat rootkit school and learn how to work around the 64bit restrictions.

If it is a kernel address there is no reliable way. For a user address you
need to put the access in a __try/__except block.

You must complete the request after the wait or non-wait since it has not been
completed. If you broke the completion sequence, you do not need to mark it
pending. If you do mark it pending, you can only return pending from your
dispatch routine. You may have cases in your dispatch routine when the incoming
IRQL is not passive, so be sure to check. Paging IO is one possibility and it

In my opinion, when to call CcCopyRead? and acquire whatever resources should be
left to the file system owning the file object who has the best knowledge of the
caching state. A filter should use higher level API to read data. The fact it
"worked" in XP does not mean it is correct -- as indicated now by the bugcheck
in Windows 7 you observe.

In a low memory situation, I want to handle an asynch Irp_MJ_WRITE
synchonously so that I have access to the Irp-> UserBuffer thru out the
entire process (i.e., don't have to probe-n-lock it). Is there a way of
doing that? Thanks.

I don't think that FltObjects-> FileObject can be NULL ever.
My filters don't even have a check for this field in the PreCreate.
And they seem to be working fine in various deployments.
FltObjects-> FileObject-> FileName.Buffer can be NULL. I guess this is when
someone is opening a handle to the volume.
With regards to management of the memory.
You can free buffer pointed by FileName.Buffer ...

Wouldn't it be more desirable to keep the application from accessing the

thousands of dollars on credit cards you never applied for or received.

Of course. The .cat contains an index of all of the files in the driver
package, including the .inf and all of the files that the .inf refers
to, along with their checksums. If you change any file in the index,
you must recreate the .cat.

Just to note that although VeriSign and GlobalSign are two popular CAs,
a certificate from any company that is a member of the Windows root

The INF is not going to help. If the hw is present, the driver will load. You
have a few options
1) yank the card out on reboot. Lame and time consuming.
2) set a breakpoint on your DriverEntry (bu vbus!DriverEntry to set an
unresolved bp that will be resolved on module load). Manually change the return
value to !NT_SUCCESS, reax=c0000001 on return from the function.
3) add a global to ...

There may (probably) are other ways to do this, which may be better or worse;

For kernel mode, I don't believe that there is an official way to do this.
