A recent commit added new variables only used if CONFIG_NETDEVICES is set. A simple fix would be to only declare these variables if the same condition is valid but Alexei suggested an even simpler solution: since CONFIG_NETDEVICES doesn't change anything in .h I think the best is to remove #ifdef CONFIG_NETDEVICES from net/core/filter.c and rely on sock_bindtoindex() returning ENOPROTOOPT in the extreme case of oddly configured kernels. Fixes: 70c58997 ("bpf: Allow SO_BINDTODEVICE opt in bpf_setsockopt") Suggested-by:
