I didn't see the thread immediately after sending the first time, so I though there is some problem with my @opensuse.org alias or SMTP server not accepting it. Please review this series, since I'm using @opensuse.org alias for upstream development more frequently than @suse.de.
From: Michal Rostecki <mrostecki@opensuse.org> This series implements a new BPF feature probe which checks for the commit c04c0d2b968a ("bpf: increase complexity limit and maximum program size"), which increases the maximum program size to 1M. It's based on the similar check in Cilium, althogh Cilium is already aiming to use bpftool checks and eventually drop all its custom checks. Examples of outputs: # bpftool feature probe [...] Scanning miscellaneous eBPF features... Large complexity limit and maximum program size (1M) is available # bpftool feature probe macros [...] /*** eBPF misc features ***/ #define HAVE_HAVE_LARGE_INSN_LIMIT # bpftool feature probe -j | jq '.["misc"]' { "have_large_insn_limit": true } Michal Rostecki (2): libbpf: Add probe for large INSN limit bpftool: Add misc secion and probe for large INSN limit tools/bpf/bpftool/feature.c | 18 ++++++++++++++++++ tools/lib/bpf/libbpf.h | 1 + tools/lib/bpf/libbpf.map | 1 + tools/lib/bpf/libbpf_probes.c | 23 +++++++++++++++++++++++ 4 files changed, 43 insertions(+)
