Merge branch 'bpf-fix-verification-of-indirect-var-off-stack-access'
Andrei Matei says:
====================
bpf: fix verification of indirect var-off stack access
V4 to V5:
- split the test into a separate patch
V3 to V4:
- include a test per Eduard's request
- target bpf-next per Alexei's request (patches didn't change)
V2 to V3:
- simplify checks for max_off (don't call
check_stack_slot_within_bounds for it)
- append a commit to protect against overflow in the addition of the
register and the offset
V1 to V2:
- fix max_off calculation for access size = 0
