Martin KaFai Lau c2fcbf81c3 bpf, selftests: Fix racing issue in btf_skc_cls_ingress test ... The libbpf CI reported occasional failure in btf_skc_cls_ingress: test_syncookie:FAIL:Unexpected syncookie states gen_cookie:80326634 recv_cookie:0 bpf prog error at line 97 "error at line 97" means the bpf prog cannot find the listening socket when the final ack is received. It then skipped processing the syncookie in the final ack which then led to "recv_cookie:0". The problem is the userspace program did not do accept() and went ahead to close(listen_fd) before the kernel (and the bpf prog) had a chance to process the final ack. The fix is to add accept() call so that the userspace will wait for the kernel to finish processing the final ack first before close()-ing everything.
