I think there are more build problems with this. Has anyone hit this before? $ CLANG=clang-12 O=../kbuild/vm ./tools/testing/selftests/bpf/vmtest.sh -j 7 GEN-SKEL [test_progs-no_alu32] bind6_prog.skel.h libbpf: elf: skipping unrecognized data section(5) .rodata.str1.1 GEN-SKEL [test_progs-no_alu32] bind_perm.skel.h libbpf: elf: skipping unrecognized data section(5) .rodata.str1.1 GEN-SKEL [test_progs-no_alu32] bpf_cubic.skel.h GEN-SKEL [test_progs-no_alu32] bpf_dctcp.skel.h GEN-SKEL [test_progs-no_alu32] bpf_flow.skel.h libbpf: failed to find BTF for extern 'tcp_cong_avoid_ai' [27] section: -2 Error: failed to open BPF object file: No such file or directory make: *** [Makefile:453: /home/lorenz/dev/kbuild/vm//no_alu32/bpf_cubic.skel.h] Error 255 make: *** Deleting file '/home/lorenz/dev/kbuild/vm//no_alu32/bpf_cubic.skel.h' make: *** Waiting for unfinished jobs.... libbpf: failed to find BTF for extern 'tcp_reno_cong_avoid' [38] section: -2 Error: failed to open BPF object file: No such file or directory make: *** [Makefile:451: /home/lorenz/dev/kbuild/vm//no_alu32/bpf_dctcp.skel.h] Error 255 make: *** Deleting file '/home/lorenz/dev/kbuild/vm//no_alu32/bpf_dctcp.skel.h' -- Lorenz Bauer | Systems Engineer 6th Floor, County Hall/The Riverside Building, SE1 7PB, UK www.cloudflare.com
