  • Article

The QueuedSpinLockRelease rule specifies that calls to KeAcquireInStackQueuedSpinLock and KeReleaseInStackQueuedSpinLock are used in strict alternation.

Moreover, at the end of a dispatch or cancel routine, the driver should not hold the queued spinlock.

Driver model: WDM

Bug check(s) found with this rule: Bug Check 0xC4: DRIVER_VERIFIER_DETECTED_VIOLATION (0x00040007)

How to test

At compile time

Run Static Driver Verifier and specify the QueuedSpinLockRelease 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.
