2019-10-17selftests/bpf: Make CO-RE reloc test impartial to test_progs flavorAndrii Nakryiko
test_core_reloc_kernel test captures its own process name and validates it as part of the test. Given extra "flavors" of test_progs, this break for anything by default test_progs binary. Fix the test to cut out flavor part of the process name.

2019-10-17selftests/bpf: Add kfree_skb raw_tp testAlexei Starovoitov
Load basic cls_bpf program. Load raw_tracepoint program and attach to kfree_skb raw tracepoint. Trigger cls_bpf via prog_test_run. At the end of test_run kernel will call kfree_skb which will trigger trace_kfree_skb tracepoint. Which will call our raw_tracepoint program.

2019-08-13selftests/bpf: fix race in flow dissector testsPetar Penkov
Since the "last_dissection" map holds only the flow keys for the most recent packet, there is a small race in the skb-less flow dissector tests if a new packet comes between transmitting the test packet, and reading its keys from the map. If this happens, the test packet keys will be overwritten and the test will fail. Changing the "last_dissection" map to a hash map, keyed on the source/dest port pair resolves this issue. Additionally, let's clear the last test results from the map between tests to prevent previous test cases from interfering with the following test cases.

2019-07-27selftests/bpf: abstract away test log outputAndrii Nakryiko
This patch changes how test output is printed out. By default, if test had no errors, the only output will be a single line with test number, name, and verdict at the end, e.g.: #31 xdp:OK If test had any errors, all log output captured during test execution will be output after test completes. It's possible to force output of log with `-v` (`--verbose`) option, in which case output won't be buffered and will be output immediately. To support this, individual tests are required to use helper methods for logging: `test__printf()` and `test__vprintf()`.
