ZwRegistryOpen rule (storport)

This rule verifies that the handle to the registry key opened via ZwOpenKey is subsequently used correctly by other ZwXxx routines. The routines ZwEnumerateKey, ZwEnumerateValueKey, ZwFlushKey, ZwQueryKey, ZwQueryValueKey, ZwSetValueKey, ZwClose, and ZwDeleteKey must not be called on a handle that isn't open. The handle must also be closed before returning.

Driver model: Storport

How to test

At compile time

Run Static Driver Verifier and specify the ZwRegistryOpen rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
