2020-05-09selftests/bpf: Move existing common networking parts into network_helpersStanislav Fomichev1-0/+14
1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users. 2. Copy-paste spin_lock_thread into two tests that use it.

2019-08-28selftests/bpf: test_progs: remove global fail/success countsStanislav Fomichev1-4/+2
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.

2019-03-12selftests/bpf: fix segfault of test_progs when prog loading failedYonghong Song1-1/+1
The test_progs subtests, test_spin_lock() and test_map_lock(), requires BTF present to run successfully. Currently, when BTF failed to load, test_progs will segfault, $ ./test_progs ... 12: (bf) r1 = r8 13: (85) call bpf_spin_lock#93 map 'hash_map' has to have BTF in order to use bpf_spin_lock libbpf: -- END LOG -- libbpf: failed to load program 'map_lock_demo' libbpf: failed to load object './test_map_lock.o' test_map_lock:bpf_prog_load errno 13 Segmentation fault The segfault is caused by uninitialized variable "obj", which is used in bpf_object__close(obj), when bpf prog failed to load. Initializing variable "obj" to NULL in two occasions fixed the problem. $ ./test_progs ...
