Merge tag 'libnvdimm-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams: "The vast bulk of this update is the new support for the security capabilities of some nvdimms. The userspace tooling for this capability is still a work in progress, but the changes survive the existing libnvdimm unit tests. The changes also pass manual checkout on hardware and the new nfit_test emulation of the security capability. The touches of the security/keys/ files have received the necessary acks from Mimi and David. Those changes were necessary to allow for a new generic encrypted-key type, and allow the nvdimm sub-system to lookup key material referenced by the libnvdimm-sysfs interface. Summary: - Add support for the security features of nvdimm devices that implement a security model similar to ATA hard drive security. The security model supports locking access to the media at device-power-loss, to be unlocked with a passphrase, and secure-erase (crypto-scramble). Unlike the ATA security case where the kernel expects device security to be managed in a pre-OS environment, the libnvdimm security implementation allows key provisioning and key-operations at OS runtime. Keys are managed with the kernel's encrypted-keys facility to provide data-at-rest security for the libnvdimm key material. The usage model mirrors fscrypt key management, but is driven via libnvdimm sysfs. - Miscellaneous updates for api usage and comment fixes" * tag 'libnvdimm-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (21 commits) libnvdimm/security: Quiet security operations libnvdimm/security: Add documentation for nvdimm security support tools/testing/nvdimm: add Intel DSM 1.8 support for nfit_test tools/testing/nvdimm: Add overwrite support for nfit_test tools/testing/nvdimm: Add test support for Intel nvdimm security DSMs acpi/nfit, libnvdimm/security: add Intel DSM 1.8 master passphrase support acpi/nfit, libnvdimm/security: Add security DSM overwrite support acpi/nfit, libnvdimm: Add support for issue secure erase DSM to Intel nvdimm acpi/nfit, libnvdimm: Add enable/update passphrase support for Intel nvdimms acpi/nfit, libnvdimm: Add disable passphrase support to Intel nvdimm. acpi/nfit, libnvdimm: Add unlock of nvdimm support for Intel DIMMs acpi/nfit, libnvdimm: Add freeze security support to Intel nvdimm acpi/nfit, libnvdimm: Introduce nvdimm_security_ops keys-encrypted: add nvdimm key format type to encrypted keys keys: Export lookup_user_key to external users acpi/nfit, libnvdimm: Store dimm id as a member to struct nvdimm libnvdimm, namespace: Replace kmemdup() with kstrndup() libnvdimm, label: Switch to bitmap_zalloc() ACPI/nfit: Adjust annotation for why return 0 if fail to find NFIT at start libnvdimm, bus: Check id immediately following ida_simple_get ...
