Hi Greg,

Please consider cherry-pick this patch series into 5.16.x stable. It includes a fix to a bug in 5.16 stable which allows a user with cap_bpf privileges to get root privileges. The patch that fixes the bug is

patch 7/9: bpf: Make per_cpu_ptr return rdonly

The rest are the depedences required by the fix patch. This patchset has been merged in mainline v5.17. The patches were not planned to backport because of its complex dependences.

How about 5.10 or 5.15? Any chance to backport them there too?

thanks,
