This patch allows to specify program flags and multiple verifier log messages for the test_loader kind of tests. For example: tools/testing/selftets/bpf/progs/foobar.c: SEC("tc") __success __log_level(7) __msg("first message") __msg("next message") __flag(BPF_F_ANY_ALIGNMENT) int buz(struct __sk_buff *skb) { ... } It was developed by Andrii Nakryiko ([1]), I reused it in a "test_verifier tests migration to inline assembly" patch series ([2]), but the series is currently stuck on my side. Andrii asked to spin this particular patch separately ([3]).
