2022-04-10selftests/bpf: Improve by-name subtest selection logic in prog_testsMykola Lysenko1-0/+8
Improve subtest selection logic when using -t/-a/-d parameters. In particular, more than one subtest can be specified or a combination of tests / subtests. -a send_signal -d send_signal/send_signal_nmi* - runs send_signal test without nmi tests -a send_signal/send_signal_nmi*,find_vma - runs two send_signal subtests and find_vma test -a 'send_signal*' -a find_vma -d send_signal/send_signal_nmi* - runs 2 send_signal test and find_vma test. Disables two send_signal nmi subtests -t send_signal -t find_vma - runs two *send_signal* tests and one *find_vma* test This will allow us to have granular control over which subtests to disable in the CI system instead of disabling whole tests. Also, add new selftest to avoid possible regression when changing prog_test test name selection logic.

2021-11-07selftests/bpf: Merge test_stub.c into testing_helpers.cAndrii Nakryiko1-0/+6
Move testing prog and object load wrappers (bpf_prog_test_load and bpf_test_load_program) into testing_helpers.{c,h} and get rid of otherwise useless test_stub.c. Make testing_helpers.c available to non-test_progs binaries as well.

2020-05-13selftests/bpf: Extract parse_num_list into generic testing_helpers.cAndrii Nakryiko1-0/+5
Add testing_helpers.c, which will contain generic helpers for test runners and tests needing some common generic functionality, like parsing a set of numbers.
