bpf: add initial suite for selftests

2016-10-18T15:35:55Z

Add a start of a test suite for kernel selftests. This moves test_verifier and test_maps over to tools/testing/selftests/bpf/ along with various code improvements and also adds a script for invoking test_bpf module. The test suite can simply be run via selftest framework, f.e.: # cd tools/testing/selftests/bpf/ # make # make run_tests Both test_verifier and test_maps were kind of misplaced in samples/bpf/ directory and we were looking into adding them to selftests for a while now, so it can be picked up by kbuild bot et al and hopefully also get more exposure and thus new test case additions.

samples: bpf: relax test_maps check

2015-01-27T01:20:40Z

hash map is unordered, so get_next_key() iterator shouldn't rely on particular order of elements. So relax this test. Fixes: ffb65f27a155 ("bpf: add a testsuite for eBPF maps") Reported-by: Michael Holzheu Signed-off-by: Alexei Starovoitov Acked-by: Daniel Borkmann Signed-off-by: David S. Miller

bpf: add a testsuite for eBPF maps

2014-11-18T18:43:59Z

. check error conditions and sanity of hash and array map APIs . check large maps (that kernel gracefully switches to vmalloc from kmalloc) . check multi-process parallel access and stress test Signed-off-by: Alexei Starovoitov Signed-off-by: David S. Miller
