This mitigates an issue introduced in GCC 15, where a {0} initializer does not guarantee zeroing the entire union [1]. The common changes under tools to support EXTRA_CFLAGS and HOST_EXTRACFLAGS are sent separately [2]. As suggested, BPF patches would be picked up via the bpf tree, so this series only includes BPF related changes. Verification on bpf-ci (with tools changes [2]: https://github.com/kernel-patches/bpf/actions/runs/26815163486 [1] https://gcc.gnu.org/gcc-15/changes.html [2] https://lore.kernel.org/all/20260602-tools_build_fix_zero_init-v7-0-631baf679fe7@arm.com/ Signed-off-by: Leo Yan --- Changes in v2: - Used strscpy() instead in patch 06 (Ihor). - Added prefix "bpf-next" in subject (Alexei). - Added patch 01 to pass host cflags to bootstrap libbpf. - Added patch 08 to avoid static LLVM linking for cross build. - Link to v1: https://lore.kernel.org/r/20260323-tools_build_fix_zero_init_bpf_only-v1-0-d1cfad2f4cd1@arm.com ==================== Link: https://patch.msgid.link/20260602-tools_build_fix_zero_init_bpf_only-v2-0-c76e5250ea1c@arm.com Signed-off-by: Alexei Starovoitov --- cf750df538b0ee8f18c00a0b7d530399df363215
