2021-09-28selftests/bpf: Switch SEC("classifier*") usage to a strict SEC("tc")Andrii Nakryiko
Convert all SEC("classifier*") uses to a new and strict SEC("tc") section name. In reference_tracking selftests switch from ambiguous searching by program title (section name) to non-ambiguous searching by name in some selftests, getting closer to completely removing bpf_object__find_program_by_title().

2020-08-21selftests: bpf: Test sockmap update from BPFLorenz Bauer
Add a test which copies a socket from a sockmap into another sockmap or sockhash. This excercises bpf_map_update_elem support from BPF context. Compare the socket cookies from source and destination to ensure that the copy succeeded. Also check that the verifier rejects map_update from unsafe contexts.
