Sets nesting/reference? Complex concatenations in vmaps?
Hi,
I am trying to use one set inside another. However, none of my two attempts work. Simplified example:
# cat test #!/usr/sbin/nft -f
table ip6 t {
define ranges = {
2001:db8:85::/60,
2001:dd8:23::/48,
# ...
}
set ONE {
type ipv6_addr
flags interval
auto-merge
counter packets 0 bytes 0
elements = { $ranges }
}
set TWO {
type icmpv6_type . icmpv6_code . ipv6_addr . ipv6_addr
flags interval
auto-merge
counter packets 0 bytes 0
elements = {
1 . 2 . ::/0 . @ONE,
3 . 4 . ::/0 . $ranges
# ...
}
}
}# nft -c -f test
test:22:19-19: Error: syntax error, unexpected @
1 . 2 . ::/0 . @ONE,
^
test:23:4-4: Error: syntax error, unexpected number
3 . 4 . ::/0 . $ranges
^
test:26:1-1: Error: syntax error, unexpected '}'
}
^# nft -v nftables v1.0.6 (Lester Gooch #5)
What is the correct way to do this?
XY: Ideally, I would also like to have similarly structured vmaps, including also 'ct state' as part of the concatenations in a complex vmap, instead of a set, e.g. (pseudo code):
iifgroup . icmpv6_type . icmpv6_code . ip6_saddr . ip6_daddr . ct_state : verdict
What is the syntax for that?
Regarding vmaps, I found that this syntax works:
icmpv6 type . icmpv6 code . ip6 saddr . ip6 daddr . ct state vmap {
1 . 1 . ::/0 . ::/0 . established : continue
}However, just like with sets, this does not work:
icmpv6 type . icmpv6 code . ip6 saddr . ip6 daddr . ct state vmap {
1 . 1 . ::/0 . @ONE . established : continue
}Is there really no way to refer to a set from within a concatenation/map?

I have yet to read the original question(s) that you sent to the list but I think the answer is that there is not.

I understand.
What about ct state? Is there a way to have something like (quoting just the inner line from the map):
1 . 1 . ::/0 . ::/0 . { established,related } : continue
I tried using the sum of hex codes instead of words but I got only errors.
