From 02fc0e73e852f78ec374004f924b9d84275d0006 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Tue, 7 Feb 2023 12:11:03 +0100 Subject: [PATCH] libbpf: Always use libbpf_err to return an error in bpf_xdp_query() In order to properly set errno, rely on libbpf_err utility routine in bpf_xdp_query() to return an error to the caller.
