Subject: [PATCH bpf 0/2] bpf fix to reject mixing ptr / scalar alu op on unpriv

Follow-up fix to 979d63d50c0c ("bpf: prevent out of bounds speculation
on pointer arithmetic") in order to reject a corner case for sanitation
when ptr / scalars are mixed in the same alu op.

Thanks!

Daniel Borkmann (2):
  bpf: fix sanitation of alu op with pointer / scalar type from different paths
  bpf: add various test cases for alu op on mixed dst register types
