From 0b206c6d1066f1ee85e4238a1e34d7437148a9a3 Mon Sep 17 00:00:00 2001 From: Kumar Kartikeya Dwivedi Date: Sat, 5 Mar 2022 04:16:44 +0530 Subject: [PATCH] bpf: Replace __diag_ignore with unified __diag_ignore_all Currently, -Wmissing-prototypes warning is ignored for GCC, but not clang. This leads to clang build warning in W=1 mode. Since the flag used by both compilers is same, we can use the unified __diag_ignore_all macro that works for all supported versions and compilers which have __diag macro support (currently GCC >= 8.0, and Clang >= 11.0). Also add nf_conntrack_bpf.h include to prevent missing prototype warning for register_nf_conntrack_bpf.
