Hi,
Static analysis with clang scan build on arch/loongarch/net/bpf_jit.h has detected a potential issue with the following commit:
commit 5dc615520c4dfb358245680f1904bad61116648e Author: Tiezhu Yang <yangtiezhu@loongson.cn> Date: Wed Oct 12 16:36:20 2022 +0800
LoongArch: Add BPF JIT support
This issue is as follows:
arch/loongarch/net/bpf_jit.h:153:23: warning: Logical disjunction always evaluates to true: imm_51_31 != 0 || imm_51_31 != 0x1fffff. [incorrectLogicOperator] if (imm_51_31 != 0 || imm_51_31 != 0x1fffff) {
The statement seems to be always true. I suspect it should it be instead:
if (imm_51_31 != 0 && imm_51_31 != 0x1fffff) {
regards,
Colin
