From 0994a54c5202114ad0e3b3a0f1326e810b23ad38 Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Mon, 25 Apr 2022 17:45:03 -0700 Subject: libbpf: Drop unhelpful "program too large" guess libbpf pretends it knows actual limit of BPF program instructions based on UAPI headers it compiled with. There is neither any guarantee that UAPI headers match host kernel, nor BPF verifier actually uses BPF_MAXINSNS constant anymore. Just drop unhelpful "guess", BPF verifier will emit actual reason for failure in its logs anyways.
