[PATCH v10 00/12] ndctl: add security support

[Dave Jiang <dave.jiang@intel.com>]

The following series implements mechanisms that utilize the sysfs knobs
provided by the kernel in order to support the Intel DSM v1.8 spec
that provides security to NVDIMM. The following abilities are added:
1. display security state
2. enable/update passphrase
3. disable passphrase
4. freeze security
5. secure erase
6. overwrite
7. master passphrase enable/update

v10:
- Remove install-encrypt-key support. setup-passphrase will take a master
  key handle in order to allow per NVDIMM master key. update-passphrase can
  take optional master key handle. (Dan)
- Rebased to latest ndctl. (Vishal)
- Moved the key management calls to ndctl/util and stop exporting. (Dan)

v9:
- Add install-encrypt-key command. (Dan)
- Change enable-passphrase to setup-passphrase. (Dan)
- Change disable-passphrase to remove-passphrase. (Dan)
- Change ndctl_dimm_get_security() to return state directly and remove
  ndctl_dimm_security_supported(). (Dan)
- Remove ND_SECURITY_UNSUPPORTED state
- change ND_SECURITY_* to NDCTL_SECURITY_*
- Fix man page issues (Dan, Jane)
- Define NDCTL_KEYSDIR in config.h (Dan)
- Break check_key_run_and_discard() to 3 helper functions. (Dan)
- Remove key path input parameter. (Dan)
- Remove master key input parameter. (Dan)
- Fixup various issues in security unit test script. (Vishal)

v8:
- Additional cleanup on test script. (Vishal)
- Change load-keys script into internal command for ndctl. (Dan)

v7:
- Added option to provide path to key directory. (Vishal)
- Cleaned up shell scripts. (Vishal)
- Cleaned up documentation. (Vishal)
- Addressed various comments from Vishal.

v6:
- Fix spelling and grammar errors for documentation. (Jing)
- Change bool for indicate master passphrase and old passphrase to enum.
- Fix key load script master key name.
- Update to match v15 of kernel patch series.

v5:
- Updated to match latest kernel interface (encrypted keys)
- Added overwrite support
- Added support for DSM v1.8 master passphrase operations
- Removed upcall related code
- Moved security state to enum (Dan)
- Change security output "security_state" to just "security". (Dan)
- Break out enable and update passphrase operation. (Dan)
- Security build can be compiled out when keyutils does not exist. (Dan)
- Move all keyutils related operations to libndctl. (Dan)

v4:
- Updated to match latest kernel interface.
- Added unit test for all security calls

v3:
- Added support to inject keys in order to update nvdimm security.

v2:
- Fixup the upcall util to match recent kernel updates for nvdimm security.
