Bug ID: 283
Summary: BPF: array ins_chk is missing an entry
Product: DPDK
Version: 19.08
Hardware: All
OS: All
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: dev@dpdk.org
Reporter: michel@digirati.com.br
Target Milestone: ---
Array ins_chk in lib/librte_bpf/bpf_validate.c has UINT8_MAX (= 255) entries;
it should be 256. So the instruction 255 is reading after the array.
I have not found this bug in my tests. I came across it while reading the code
to understand how to use libbpf in my code.
