From a6850fa388f6f6ff365b3b72cb71e6d9a8a614ed Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ricardo=20B=2E=20Marli=C3=A8re?= Date: Tue, 2 Jun 2026 10:02:50 -0300 Subject: [PATCH] selftests/bpf: Add BPF_STRICT_BUILD toggle MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Distro kernels often lack BTF types or kernel features required by some BPF selftests, causing the build to abort on the first failure and preventing the remaining tests from running. Add BPF_STRICT_BUILD (default 1) to control build failure tolerance. When set to 0, the PERMISSIVE make variable is assigned a non-empty value that subsequent Makefile rules use to make individual build steps non-fatal. When set to 1 (the default), the build fails on any error, preserving the existing behavior for CI and direct builds. Users can opt in to permissive mode on the command line: make -C tools/testing/selftests \ TARGETS=bpf SKIP_TARGETS= BPF_STRICT_BUILD=0 Suggested-by: Alan Maguire Signed-off-by: Ricardo B.
