From 720f228e8d3128b7ab1d39f51fdd8da07a7640c9 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Tue, 12 Dec 2017 02:25:32 +0100 Subject: bpf: fix broken BPF selftest build At least on x86_64, the kernel's BPF selftests seemed to have stopped to build due to 618e165b2a8e ("selftests/bpf: sync kernel headers and introduce arch support in Makefile"): [...] In file included from test_verifier.c:29:0: ../../../include/uapi/linux/bpf_perf_event.h:11:32: fatal error: asm/bpf_perf_event.h: No such file or directory #include ^ compilation terminated. [...] While pulling in tools/arch/*/include/uapi/asm/bpf_perf_event.h seems to work fine, there's no automated fall-back logic right now that would do the same out of tools/include/uapi/asm-generic/bpf_perf_event.h. The usual convention today is to add a include/[uapi/]asm/ equivalent that would pull in the correct arch header or generic one as fall-back, all ifdef'ed based on compiler target definition. It's similarly done also in other cases such as tools/include/asm/barrier.h, thus adapt the same here.
