[PATCH v5 0/4] generic and PowerPC SED Opal keystore

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Greg Joyce <gjoyce@xxxxxxxxxxxxxxxxxx>

Generic functions have been defined for accessing SED Opal keys.
The generic functions are defined as weak so that they may be superseded
by keystore specific versions.

PowerPC/pseries versions of these functions provide read/write access
to SED Opal keys in the PLPKS keystore.

The SED block driver has been modified to read the SED Opal
keystore to populate a key in the SED Opal keyring. Changes to the
SED Opal key will be written to the SED Opal keystore.

Patch 3 "keystore access for SED Opal keys" is dependent on:
        https://lore.kernel.org/keyrings/20220818143045.680972-4-gjoyce@xxxxxxxxxxxxxxxxxx/T/#u

Changelog
v5:	- updated to reflect changes in PLPKS API

v4:
        - scope reduced to cover just SED Opal keys
        - base SED Opal keystore is now in SED block driver
        - removed use of enum to indicate type
        - refactored common code into common function that read and
          write use
        - removed cast to void
        - added use of SED Opal keystore functions to SED block driver

v3:
        - No code changes, but per reviewer requests, adding additional
          mailing lists(keyring, EFI) for wider review.

v2:
        - Include feedback from Gregory Joyce, Eric Richter and
          Murilo Opsfelder Araujo.
        - Include suggestions from Michael Ellerman.
        - Moved a dependency from generic SED code to this patchset.
          This patchset now builds of its own.
