Alexei Starovoitov 687f07156b bpf: fix out of bounds access in verifier log ... when the verifier log is enabled the print_bpf_insn() is doing bpf_alu_string[BPF_OP(insn->code) >> 4] and bpf_jmp_string[BPF_OP(insn->code) >> 4] where BPF_OP is a 4-bit instruction opcode. Malformed insns can cause out of bounds access. Fix it by sizing arrays appropriately. The bug was found by clang address sanitizer with libfuzzer.
