From 669dc4d76d0ecc2d795df735839f43cfddf9f617 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Fri, 23 Sep 2016 01:28:36 +0200 Subject: [PATCH] bpf: use bpf_get_smp_processor_id_proto instead of raw one Same motivation as in commit 80b48c445797 ("bpf: don't use raw processor id in generic helper"), but this time for XDP typed programs. Thus, allow for preemption checks when we have DEBUG_PREEMPT enabled, and otherwise use the raw variant. Signed-off-by: Daniel Borkmann Acked-by: Alexei Starovoitov Signed-off-by: David S.
