Announcement: GCC BPF is now being tested on BPF CI

Hi everyone. GCC BPF support in BPF CI has been landed. The BPF CI dashboard is here: https://github.com/kernel-patches/bpf/actions/workflows/test.yml A summary of what happens on CI (relevant to GCC BPF): * Linux Kernel is built on a target source revision * Latest snapshots of GCC 15 and b

Re: Errors compiling BPF programs from Linux selftests/bpf with GCC

Hi everyone. I built and ran selftests/bpf with GCC 15-20241229, and would like to share my findings. Building required small adjustments in the Makefile, besides -std=gnu17 With the following change we can mitigate int64_t issue: +progs/test_cls_redirect.c-CFLAGS := -nostdinc +progs/test_cls_r

Errors compiling BPF programs from Linux selftests/bpf with GCC

Hello everyone. I picked up the work adding GCC BPF backend to BPF CI pipeline [1], originally done by Cupertino Miranda [2]. I encountered issues compiling BPF objects for selftests/bpf with recent GCC 15 snapshots. An additional test runner binary is supposed to be generated by tools/testing/se
