I have a a minifilter-driver and in the DriverEntry() I am calling IoCreateDevice() giving it a name in a form of \Device\Blabla. After this I create a symbolic link and make the device accessible for UM. This device is later used for UM --> KM communication, mainly for sending IOCTLs.
There is one thing I am trying to achieve additionally:
What if I wanted to obtain a device handle but in the kernel mode? So i am calling ZwCreateFile or NtCreateFile using different device name formats. But this always fails. So far I have tried:
Also: ObOpenObjectByPointer() worked on the device object but the handle I got was bogus.
Any help would be appreciated.
