Minimal supplement to upstream Kernel Self Protection Project changes. Features already provided by SELinux + Yama and archs other than multiarch arm64 / x86_64 aren't in scope. Only tags have stable history. Shared IRC channel with KSPP: irc.libera.chat #linux-hardening
The HuC authentication is done by host2guc call. The HuC RSA keys are sent to GuC for authentication. v2: rebased on top of drm-tip. Changed name format and upped version 1.7. v3: changed wait_for_atomic to wait_for v4: rebased. Rename intel_huc_auh() to intel_guc_auth_huc() and place the prototype in intel_guc.h,correct the comments. v5: rebased. Moved intel_guc_auth_huc from i915_guc_submission.c to intel_uc.c.Update dev to dev_priv in intel_guc_auth_huc(). Renamed HOST2GUC_ACTION_AUTHENTICATE_HUC TO INTEL_GUC_ACTION_ AUTHENTICATE_HUC v6: rebased. Add newline on DRM_ERRORs that already dont have one. v7: rebased. Replace wait_for with intel_wait_for_register() since the latter employs sleep optimisations for quick responses- as pointed out by Chris Wilson. v8: rebased. Cleanup the intel_guc_auth_huc() by removing checks already performed in earlier functions. Make comments more descriptive. v9: rebased. Changed the bias for pinning the HuC object. Move intel_guc_auth_huc() to intel_huc.c. Change DRM_DEBUGs to DRM_ERRORs in intel_guc_auth_huc(). Add return status to DRM_ERRORs. v10: Remove message not required for the user..

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
