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"
