Linus Torvalds 75f95da078 libnvdimm for 4.21
* 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.

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.
