2019-11-24selftests/bpf: Add verifier tests for better jmp32 register boundsYonghong Song1-0/+83
Three test cases are added. Test 1: jmp32 'reg op imm'. Test 2: jmp32 'reg op reg' where dst 'reg' has unknown constant and src 'reg' has known constant Test 3: jmp32 'reg op reg' where dst 'reg' has known constant and src 'reg' has unknown constant Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20191121170651.449096-1-yhs@fb.com
2019-02-05selftests/bpf: add "any alignment" annotation for some testsBjörn Töpel1-0/+22
RISC-V does, in-general, not have "efficient unaligned access". When testing the RISC-V BPF JIT, some selftests failed in the verification due to misaligned access. Annotate these tests with the F_NEEDS_EFFICIENT_UNALIGNED_ACCESS flag. Signed-off-by: Björn Töpel <bjorn.topel@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
