+# interface using an IOCTL on a UDP INET socket, which isn't allowed here.
+# If that fails, it falls back to using libc's if_nameindex() which requires
+# a netlink route socket, which HALs may use. Due to the initial
+# attempt to use a UDP socket, we still see a selinux denial,
+# but it is safe to ignore.

+# libqdi and have all its clients use netlink route
+# sockets.
