File perf-bpf-Fix-building-perf-with-BUILD_BPF_SKEL-1-by-default-in-more-distros.patch of Package perf.27729
From: Song Liu <songliubraving@fb.com> Date: Fri, 3 Dec 2021 19:32:34 +0000 Subject: perf bpf: Fix building perf with BUILD_BPF_SKEL=1 by default in more distros Git-commit: f7c4e85bccea960203e5872553957511df86913e Patch-mainline: v5.16-rc5 References: git-fixes X-Info: dependent patch for 5a897531e00243cebbcc4dbe4ab06cd559ccf53f Arnaldo reported that building all his containers with BUILD_BPF_SKEL=1 to then make this the default he found problems in some distros where the system linux/bpf.h file was being used and lacked this: util/bpf_skel/bperf_leader.bpf.c:13:20: error: use of undeclared identifier 'BPF_F_PRESERVE_ELEMS' __uint(map_flags, BPF_F_PRESERVE_ELEMS); So use instead the vmlinux.h file generated by bpftool from BTF info. This fixed these as well, getting the build back working on debian:11, debian:experimental and ubuntu:21.10: In file included from In file included from util/bpf_skel/bperf_leader.bpf.cutil/bpf_skel/bpf_prog_profiler.bpf.c::33: : In file included from In file included from /usr/include/linux/bpf.h/usr/include/linux/bpf.h::1111: : /usr/include/linux/types.h/usr/include/linux/types.h::55::1010:: In file included from util/bpf_skel/bperf_follower.bpf.c:3fatal errorfatal error: : : In file included from /usr/include/linux/bpf.h:'asm/types.h' file not found11'asm/types.h' file not found: /usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found #include <asm/types.h>#include <asm/types.h> ^~~~~~~~~~~~~ ^~~~~~~~~~~~~ #include <asm/types.h> ^~~~~~~~~~~~~ 1 error generated.
