SpinLock rule (storport)

  • Article

This rule verifies that a call to KeAcquireSpinLock is promptly followed by a call to KeReleaseSpinlock. If a driver calls KeAcquireSpinLockRaiseToDpc or KeAcquireSpinLock again prior to releasing the lock, it fails the rule. In addition, before exiting the dispatch or cancel routine, the driver must release the spin lock.

Driver model: Storport

How to test

At compile time

Run Static Driver Verifier and specify the SpinLock 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.
