2021-09-28selftests/bpf: Switch SEC("classifier*") usage to a strict SEC("tc")Andrii Nakryiko1-4/+3
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().

2020-09-17selftests/bpf: Add tailcall_bpf2bpf testsMaciej Fijalkowski1-0/+38
Add four tests to tailcalls selftest explicitly named "tailcall_bpf2bpf_X" as their purpose is to validate that combination of tailcalls with bpf2bpf calls are working properly. These tests also validate LD_ABS from subprograms. Signed-off-by: Maciej Fijalkowski <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]>
