Hi,

Is there an easy fix for this? It looks like the OS provides very old system headers. Since it's not possible to write linux code that compiled on a random OS, we provide syz-env container for building. If there is no easy fix, I would say the solution is to use syz-env (or a newer OS, IFLA_HSR_SLAVE1 was added >10 years ago).
