nftables bug?? Maybe

[Evgeniy Yakubov <yacudzer@xxxxxxx>]

Hello, Netfilter-devel.


I tried to make autoload rules to nftables.

First, I created file with set of ipv4 addresses and apply it:

yacudzer@adm-ovpn-03:/etc/nftables$ cat OpenVPN_set_PRD-RMQ-star.nft
table ip filter {
    set OpenVPN_set_PRD-RMQ-star {
        type ipv4_addr
        elements = {
                    10.22.0.62,                   10.22.0.93,                   10.22.0.95
        }
    }
}
yacudzer@adm-ovpn-03:/etc/nftables$ sudo nft -f OpenVPN_set_PRD-RMQ-star.nft


Then, I created file with applying this set:
yacudzer@adm-ovpn-03:/etc/nftables$ cat ovpn-RabbitMQ.nft
add chain filter OpenVPN-RabbitMQ
flush chain filter OpenVPN-RabbitMQ

table ip filter {
    set OpenVPN_set_PRD-RMQ-star {
        type ipv4_addr
        elements = {
                    10.22.0.62,                   10.22.0.93,                   10.22.0.95
        }
    }
        chain OpenVPN-RabbitMQ {
                ip daddr @OpenVPN_set_PRD-RMQ-star accept
                return
        }
}

And when I tried to apply it, I see this error message:
yacudzer@adm-ovpn-03:/etc/nftables$ sudo nft -f ovpn-RabbitMQ.nft
ovpn-RabbitMQ.nft:6:26-50: Error: Set 'OpenVPN_set_PRD-RMQ-star' does not exist
                ip daddr @OpenVPN_set_PRD-RMQ-star accept
                                       ^^^^^^^^^^^^^^^^^^^^^^^^^

If I place set rule in same file - everything OK:

yacudzer@adm-ovpn-03:/etc/nftables$ cat ovpn-RabbitMQ.nft
add chain filter OpenVPN-RabbitMQ
flush chain filter OpenVPN-RabbitMQ

table ip filter {
    set OpenVPN_set_PRD-RMQ-star {
        type ipv4_addr
        elements = {
                    10.22.0.62,                   10.22.0.93,                   10.22.0.95
        }
    }
        chain OpenVPN-RabbitMQ {
                ip daddr @OpenVPN_set_PRD-RMQ-star accept
                return
        }
}
yacudzer@adm-ovpn-03:/etc/nftables$ sudo nft -f ovpn-RabbitMQ.nft


But error only when set and rule in different files.
I think that it a bug.

I tried versions 0.9.0 (in debian repo) and 0.9.6 (compiled manually).
