Sorry for the confusion, results are indeed confusing to me . If I try with git bisect I get git bisect bad 9d6f67365d9cdb389fbdac2bb5b00e59e345930e is the first bad commit If I try to test myself with multiple test scenarios(I have mentioned in the previous mails) for the bad commits , I see that bad commits are bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds() selftests/bpf: Fix test_align verifier log patterns selftests/bpf: Fix "dubious pointer arithmetic" test Thanks, Rajesh Dasari.
