Handling IRP_MN_BOGUS.

OSR_Community_User · November 29, 2006, 8:15pm

Hi All,
The Driver verifier is giving a bug check for my WDM function
driver. Teh details are attached at the end of the mail and I really do
not know how to handle this IRP.
Any help is appriciated. My driver does not handle the
IRP_MJ_SYSTEM_CONTROL and does not register this dispatch routine at
all. Is it a requirement to handle this major function.
My driver is not a WMI data provider and hence this dispatch routine is
not provided.

Any help is highly appriciated.

Thanks in advance,

Aj

Yes, as a pnp driver you must handle pnp/power/wmi even if you don’t do anything with them. Have you considered using KMDF to write your driver instead of using WDM ?Since it appears you are starting from scratch, there is no conversion issue and KMDF will make all of these problems go away and let you focus on the problem you are trying to solve vs the requirements of the OS to have your driver load and run properly.

I’m sure you’re not required to support the WMI irp. My best guess is that your DRIVER_OBJECT has been corrupted in the vicinity of its dispatch table.

One thing I’d try is dumping the driver object, find the address of the dispatch table, and do a dds on that table. Or some other dump, the idea being that the corrupted entry may be followed by other data or may in itself give some idea what the corrupting source is.

Another would be to break on DriverEntry, find the address of this entry [ntddk.h or wdm.h give the indices], and set a write access breakpoint on it [problem is that the corruption could happen on any of the 4 bytes, and the size of the write is also unknown, which is why I’d look at the corrupting values first]. Then run until that breakpoint gets hit [if the bugcheck comes first, then it was probably the wrong breakpoint]. Of course, if the value at DriverEntry is the same as what you saw in the bugcheck, then my whole initial guess is bogus.

Guesses do have that problem…

Did you do this:

or did you do this:

The latter should be correct.
