The following series implements security support for nvdimm. Mostly adding
new security DSM support from the Intel NVDIMM DSM spec v1.7, but also
adding generic support libnvdimm for other vendors. The most important
security features are unlocking locked nvdimms, and updating/setting security
passphrase to nvdimms.
Security folks, thanks in advance for taking a look at my key management
implementation and making sure that I'm doing something sane. Mainly you'll
want to review patches 2, 4, and 5 as most relevant ones that need scrutiny.
v2:
- Move inclusion of intel.h to relevant source files and not in nfit.h. (Dan)
- Moved security ring relevant code to dimm_devs.c. (Dan)
- Added dimm_id to nfit_mem to avoid recreate per sysfs show call. (Dan)
- Added routine to return security_ops based on family supplied. (Dan)
- Added nvdimm_key_data struct to wrap raw passphrase string. (Dan)
- Allocate firmware package on stack. (Dan)
- Added missing frozen state detection when retrieving security state.
