We (illumos) do have that! http://src.illumos.org/source/xref/illumos-gate/usr/src/lib/libsocket/inet/getifaddrs.c

I think we just might have to add libsocket to the linker libraries?

    IIRC you can patch /opt/homeassistant/lib/python3.7/site-packages/ifaddr/_posix.py to use libsocket instead of libc and it works.

    Also see ifaddr/ifaddr#23
