selftests/bpf: add bpf_spin_lock verifier tests

2019-02-01T19:55:39Z

add bpf_spin_lock tests to test_verifier.c that don't require latest llvm with BTF support Signed-off-by: Alexei Starovoitov Signed-off-by: Daniel Borkmann

selftests/bpf: skip verifier tests for unsupported map types

2019-01-31T09:13:21Z

Use recently introduced bpf_probe_map_type() to skip tests in the test_verifier if map creation (create_map) fails. It's handled explicitly for each fixup, i.e. if bpf_create_map returns negative fd, we probe the kernel for the appropriate map support and skip the test is map type is not supported.

selftests/bpf: skip verifier tests for unsupported program types

2019-01-31T09:13:21Z

Use recently introduced bpf_probe_prog_type() to skip tests in the test_verifier() if bpf_verify_program() fails. The skipped test is indicated in the output. Example: ... 679/p bpf_get_stack return R0 within range SKIP (unsupported program type 5) 680/p ld_abs: invalid op 1 OK ... Summary: 863 PASSED, 165 SKIPPED, 3 FAILED Signed-off-by: Stanislav Fomichev Signed-off-by: Daniel Borkmann

selftests: bpf: break up the rest of test_verifier

2019-01-28T05:37:45Z

Break up the rest of test_verifier tests into separate files. Signed-off-by: Jakub Kicinski Acked-by: Jiong Wang Signed-off-by: Alexei Starovoitov

selftests: bpf: break up test_verifier

2019-01-28T05:37:45Z

Break up the first 10 kLoC of test verifier test cases out into smaller files. Looks like git line counting gets a little flismy above 16 bit integers, so we need two commits to break up test_verifier. Signed-off-by: Jakub Kicinski Acked-by: Jiong Wang Signed-off-by: Alexei Starovoitov

selftests: bpf: prepare for break up of verifier tests

2019-01-28T05:37:45Z

test_verifier.c has grown to be very long (almost 16 kLoC), and it is very conflict prone since we always add tests at the end. Try to break it apart a little bit. Allow test snippets to be defined in separate files and include them automatically into the huge test array. Signed-off-by: Jakub Kicinski Acked-by: Jiong Wang Signed-off-by: Alexei Starovoitov

selftests: bpf: functional and min/max reasoning unit tests for JMP32

2019-01-26T21:33:02Z

This patch adds unit tests for new JMP32 instructions. This patch also added the new BPF_JMP32_REG and BPF_JMP32_IMM macros to samples/bpf/bpf_insn.h so that JMP32 insn builders are available to tests under 'samples' directory.

bpf: allow BPF programs access skb_shared_info->gso_segs field

2019-01-24T09:49:05Z

This adds the ability to read gso_segs from a BPF program. v3: Use BPF_REG_AX instead of BPF_REG_TMP for the temporary register, as suggested by Martin. v2: refined Eddie Hao patch to address Alexei feedback.

selftests: bpf: add tests for dead code removal

2019-01-24T01:35:32Z

Add tests for newly added dead code elimination. Both verifier and BTF tests are added. BTF test infrastructure has to be extended to be able to account for line info which is eliminated during dead code removal.

bpf: add various test cases for alu op on mixed dst register types

2019-01-06T05:32:38Z

Add couple of test_verifier tests to check sanitation of alu op insn with pointer and scalar type coming from different paths. This also includes BPF insns of the test reproducer provided by Jann Horn. Signed-off-by: Daniel Borkmann Acked-by: Alexei Starovoitov Signed-off-by: Alexei Starovoitov
