selftests/bpf: Do not export subtest as standalone test Two subtests in ksyms_module.c are not qualified as static, so these subtests are exported as standalone tests in tests.h and lead to confusion for the output of "./test_progs -t ksyms_module". By using the following command ... grep "^void \(serial_\)\?test_[a-zA-Z0-9_]\+(\(void\)\?)" \ tools/testing/selftests/bpf/prog_tests/*.c | \ awk -F : '{print $1}' | sort | uniq -c | awk '$1 != 1' ... one finds out that other tests also have a similar problem, so fix these tests by marking subtests in these tests as static.

selftests/bpf: Migrate from bpf_prog_test_run bpf_prog_test_run is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK in most cases, so replace usages with ASSERT_* calls.

selftests/bpf: Add weak/typeless ksym test for light skeleton Also, avoid using CO-RE features, as lskel doesn't support CO-RE, yet. Include both light and libbpf skeleton in same file to test both of them together. In c48e51c8b07a ("bpf: selftests: Add selftests for module kfunc support"), I added support for generating both lskel and libbpf skel for a BPF object, however the name parameter for bpftool caused collisions when included in same file together. This meant that every test needed a separate file for a libbpf/light skeleton separation instead of subtests. Change that by appending a "_lskel" suffix to the name for files using light skeleton, and convert all existing users.

bpf: selftests: Add selftests for module kfunc support This adds selftests that tests the success and failure path for modules kfuncs (in presence of invalid kfunc calls) for both libbpf and gen_loader. It also adds a prog_test kfunc_btf_id_list so that we can add module BTF ID set from bpf_testmod. This also introduces a couple of test cases to verifier selftests for validating whether we get an error or not depending on if invalid kfunc call remains after elimination of unreachable instructions.
