Subject: [PATCH v2 0/2] Fixes for security locked drives
Date: Mon,  6 Jul 2026 14:00:52 -0700	[thread overview]
Message-ID: <20260706210054.1336654-1-tadamsjr@google.com> (raw)
In-Reply-To: <akaHPScetfl1VbF8@ryzen>

These patches improve libata handling of locked drives.

Changes since v1:
- Simplified the n_sectors check in ata_dev_revalidate() as suggested by
  Niklas
- Added Patch 2 to disable HPA resizing for locked drives to address
  Sashiko's feedback.

Testing:
- Verified using the internal test suite that originally detected the regression.
- The issue can be reproduced manually using the steps outlined in the thread
  (runtime locking, disabling SSP, active I/O, and link reset).

  ata: libata-core: Allow capacity transition to zero for locked drives
