selftests/bpf: fix perf_buffer on s390

2019-07-17T01:41:00+00:00

perf_buffer test fails for exactly the same reason test_attach_probe used to fail: different nanosleep syscall kprobe name. Reuse the test_attach_probe fix.

selftests/bpf: skip nmi test when perf hw events are disabled

2019-07-16T16:24:46+00:00

Some setups (e.g. virtual machines) might run with hardware perf events disabled. If this is the case, skip the test_send_signal_nmi test. Add a separate test involving a software perf event. This allows testing the perf event path regardless of hardware perf event support. Signed-off-by: Ilya Leoshkevich Acked-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov

selftests/bpf: fix attach_probe on s390

2019-07-15T21:09:40+00:00

attach_probe test fails, because it cannot install a kprobe on a non-existent sys_nanosleep symbol. Use the correct symbol name for the nanosleep syscall on 64-bit s390. Don't bother adding one for 31-bit mode, since tests are compiled only in 64-bit mode.

selftests/bpf: convert existing tracepoint tests to new APIs

2019-07-05T20:37:31+00:00

Convert some existing tests that attach to tracepoints to use bpf_program__attach_tracepoint API instead. Signed-off-by: Andrii Nakryiko Reviewed-by: Stanislav Fomichev Acked-by: Song Liu Signed-off-by: Daniel Borkmann

selftests/bpf: add kprobe/uprobe selftests

selftests/bpf: switch test to new attach_perf_event API

selftests/bpf: add realistic loop tests

2019-06-19T00:22:52+00:00

Add a bunch of loop tests. Most of them are created by replacing '#pragma unroll' with '#pragma clang loop unroll(disable)' Several tests are artificially large: /* partial unroll. llvm will unroll loop ~150 times. * C loop count -> 600. * Asm loop count -> 4. * 16k insns in loop body. * Total of 5 such loops. Total program size ~82k insns. */ "./pyperf600.o", /* no unroll at all. * C loop count -> 600. * ASM loop count -> 600. * ~110 insns in loop body. * Total of 5 such loops. Total program size ~1500 insns. */ "./pyperf600_nounroll.o", /* partial unroll. 19k insn in a loop. * Total program size 20.8k insn. * ~350k processed_insns */ "./strobemeta.o", Signed-off-by: Alexei Starovoitov Acked-by: Andrii Nakryiko Signed-off-by: Daniel Borkmann
