With modifications of page tables, this can lead to privilege # escalation. This exposure is limited to the Guest Physical Address # space and does not allow for access outside of the graphics virtual # machine. # # This series establishes a software parser into the Blitter command # stream to scan for, and prevent, reads or writes to MMIO's that should # not be accessible to non-privileged contexts. # # Much of the command parser infrastructure has existed for some time, # and is used on Ivybridge/Haswell/Valleyview derived products to allow # the use of features normally blocked by hardware. In this legacy # context, the command parser is employed to allow normally unprivileged # submissions to be run with elevated privileges in order to grant # access to a limited set of extra capabilities. In this mode the parser # is optional; In the event that the parser finds any construct that it # cannot properly validate (e.g. nested command buffers), it simply # aborts the scan and submits the buffer in non-privileged mode. # # For Gen9 Graphics, this series makes the parser mandatory for all # Blitter submissions. The incoming user buffer is first copied to a # kernel owned buffer, and parsed. If all checks are successful the # kernel owned buffer is mapped READ-ONLY and submitted on behalf of the # user. If any checks fail, or the parser is unable to complete the scan # (nested buffers), it is forcibly rejected. The successfully scanned # buffer is executed with NORMAL user privileges (key difference from # legacy usage). # # Modern usermode does not use the Blitter on later hardware, having # switched over to using the 3D engine instead for performance reasons. # There are however some legacy usermode apps that rely on Blitter, # notably the SNA X-Server. There are no known usermode applications # that require nested command buffers on the Blitter, so the forcible # rejection of such buffers in this patch series is considered an # acceptable limitation" # # * Intel graphics fixes in emailed bundle from Jon Bloomfield <jon.bloomfield@intel.com>: # drm/i915/cmdparser: Fix jump whitelist clearing # drm/i915/gen8+: Add RC6 CTX corruption WA #
