From: Dan Williams <dan.j.williams@intel.com> To: linux-nvdimm@lists.01.org Cc: linux-kernel@vger.kernel.org Subject: [PATCH 0/3] libnvdimm/security: Enumerate the frozen state and other cleanups Date: Wed, 14 Aug 2019 18:20:13 -0700 [thread overview] Message-ID: <156583201347.2815870.4687949334637966672.stgit@dwillia2-desk3.amr.corp.intel.com> (raw) Jeff reported a scenario where ndctl was failing to unlock DIMMs [1]. Through the course of debug it was discovered that the security interface on the DIMMs was in the 'frozen' state disallowing unlock, or any security operation. Unfortunately the kernel only showed that the DIMMs were 'locked', not 'locked' and 'frozen'. Introduce a new sysfs 'frozen' attribute so that ndctl can reflect the "security-operations-allowed" state independently of the lock status. Then, followup with cleanups related to replacing a security-state-enum with a set of flags.
