<pre>If consequent elements are added to set with flag interval in one command, they
get concatenated. But when they are added with separate commands, they don't.
This is inconsistent behaviour and needs to be fixed. Listing of such sets and
keeping them in consistence with external data is problematic because of that.
Please disable implicit concatenating for good (maybe except sets with flag
constant) or introduce nft option to let concatenating is not performed for
given operation.
Current (bad) behaviour:
a) adding consequent elements in one command
nft add set t test_set {type ipv4_addr\; flags interval\;}
nft add element t test_set {192.168.0.0, 192.168.0.1}
nft list set t test_set
table ip t {
set test_set {
type ipv4_addr
flags interval
elements = { 192.168.0.0/31 }
}
}
b) adding consequent elements in separate commands
nft flush set t test_set
nft add element t test_set {192.168.0.0}
nft add element t test_set {192.168.0.1}
nft list set t test_set
table ip t {
set test_set {
type ipv4_addr
flags interval
elements = { 192.168.0.0, 192.168.0.1 }
}
}</pre>
