libbpf: Make DECLARE_LIBBPF_OPTS macro strictly a variable declaration

2019-10-22T19:35:03Z

LIBBPF_OPTS is implemented as a mix of field declaration and memset + assignment. This makes it neither variable declaration nor purely statements, which is a problem, because you can't mix it with either other variable declarations nor other function statements, because C90 compiler mode emits warning on mixing all that together. This patch changes LIBBPF_OPTS into a strictly declaration of variable and solves this problem, as can be seen in case of bpftool, which previously would emit compiler warning, if done this way (LIBBPF_OPTS as part of function variables declaration block). This patch also renames LIBBPF_OPTS into DECLARE_LIBBPF_OPTS to follow kernel convention for similar macros more closely. v1->v2: - rename LIBBPF_OPTS into DECLARE_LIBBPF_OPTS (Jakub Sitnicki).

selftests/bpf: Make reference_tracking test use subtests

2019-10-21T12:49:12Z

reference_tracking is actually a set of 9 sub-tests. Make it explicitly so. Also, add explicit "classifier/" prefix to BPF program section names to let libbpf correctly guess program type. Thus, also remove explicit bpf_prog__set_type() call. Signed-off-by: Andrii Nakryiko Signed-off-by: Daniel Borkmann Link: https://lore.kernel.org/bpf/20191021033902.3856966-7-andriin@fb.com

selftests/bpf: switch tests to new bpf_object__open_{file, mem}() APIs

2019-10-06T01:09:48Z

Verify new bpf_object__open_mem() and bpf_object__open_file() APIs work as expected by switching test_attach_probe test to use embedded BPF object and bpf_object__open_mem() and test_reference_tracking to bpf_object__open_file(). Signed-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov

selftests/bpf: test_progs: remove global fail/success counts

2019-08-27T22:35:40Z

Now that we have a global per-test/per-environment state, there is no longer need to have global fail/success counters (and there is no need to save/get the diff before/after the test). Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests to it. CHECK_FAIL uses new test__fail() to record the failure.

selftest/bpf: centralize libbpf logging management for test_progs

2019-07-28T05:36:19Z

Make test_progs test runner own libbpf logging. Also introduce two levels of verbosity: -v and -vv. First one will be used in subsequent patches to enable test log output always. Second one increases verbosity level of libbpf logging further to include debug output as well. Signed-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov
