I tried to build dnsdist with the ebpf filter. But it looks like it fails, while the kernel config CONFIG_BPF_SYSCALL is not set. I can build dnsdist with ebpf, but can not use it then.

CONFIG_BPF and CONFIG_BPF_JIT is set to y. CONFIG_BPF_SYSCALL is not set.

I'm on 4.9.32-0-virthardened (Alpine 3.6.2)

Is there any reason, way the syscall-config is not set?
