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
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.
