[Heinrich Schuchardt <2036604@xxxxxxxxxxxxxxxxxx>]

Hello Dann,

The UEFI specification requires that if a 64 KiB page contains either of

– EfiRuntimeServicesCode
– EfiRuntimeServicesData
– EfiReserved
– EfiACPIMemoryNVS

then all 4KiB pages in the 64KiB page must use identical attributes.

So additionally to the cited patch you must ensure that buffer allocated
with AllocatePages() in handle_image() for which you set memory
attributes does not contain any of the above memory types. The easiest
way to fulfill the requirement is appropriate alignment and rounding of
the used memory. I can't find this in upstream shim.

Best regards

Heinrich

Bug description:
  I try to create an autopkgtest VM on an arm64 system with

  autopkgtest-buildvm-ubuntu-cloud -v --release mantic

  or on an amd64 system with

  autopkgtest-buildvm-ubuntu-cloud --arch arm64 -v --release mantic

  In both cases I get:
