Use the dynamic datatype to allocate an instance of TYPE_INTEGER and set
length and byteorder. Add missing information to the set userdata area
for raw payload expressions which allows to rebuild the set typeof from
the listing path.
A few examples:
- With anonymous sets:
nft add rule x y ip saddr . @ih,32,32 { 1.1.1.1 . 0x14, 2.2.2.2 . 0x1e }
- With named sets:
table x {
set y {
typeof ip saddr . @ih,32,32
elements = { 1.1.1.1 . 0x14 }
}
}
Incremental updates are also supported, eg.
nft add element x y { 3.3.3.3 . 0x28 }
expr_evaluate_concat() is used to evaluate both set key definitions
and set key values, using two different function might help to simplify
this code in the future.
