From 3dea5920365d06a5f17e33b02f0c3d5e272e09f9 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Tue, 12 Dec 2017 02:25:31 +0100 Subject: [PATCH 124/241] bpf: fix build issues on um due to mising bpf_perf_event.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CVE-2017-5754 [ Note, this is a Git cherry-pick of the following commit: a23f06f06dbe ("bpf: fix build issues on um due to mising bpf_perf_event.h") ... for easier x86 PTI code testing and back-porting. ] Since c895f6f703ad ("bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type") um (uml) won't build on i386 or x86_64: [...] CC init/main.o In file included from ../include/linux/perf_event.h:18:0, from ../include/linux/trace_events.h:10, from ../include/trace/syscall.h:7, from ../include/linux/syscalls.h:82, from ../init/main.c:20: ../include/uapi/linux/bpf_perf_event.h:11:32: fatal error: asm/bpf_perf_event.h: No such file or directory #include [...] Lets add missing bpf_perf_event.h also to um arch. This seems to be the only one still missing.
