Rajesh reports [1] that the test_align BPF selftest is broken in 5.4.210. Three patches were added since 5.4.209:
(A) 7c1134c7da99 ("bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds()") (B) 6a9b3f0f3bad ("selftests/bpf: Fix test_align verifier log patterns") (C) 6098562ed9df ("selftests/bpf: Fix "dubious pointer arithmetic" test")
(A) fixes an issue in the BPF verifier, which changes the verifier trace output. (B) fixes those trace changes in the selftests.
Unfortunately (B) also address changes to the verifier output from other patches that weren't backported to v5.4, so the test now fails. (C) also addresses a different verifier change that is not in v5.4.
Therefore revert (C), and partially revert (B).
