I am getting the following error when I try to load the following file using
"nft -f"
File:
define pri = filter
table inet global {
chain prerouting {
type filter hook prerouting priority $pri
policy accept
}
}
Error:
priority_test:1:14-19: Error: No symbol type information
define pri = filter
^^^^^^
priority_test:4:37-49: Error: invalid priority expression symbol in this
context.
type filter hook prerouting priority $pri
^^^^^^^^^^^^^
The original idea was to evaluate the prio_expr and check the result expression
datatype. This way we could use variables with number priority number and also
strings. It seems that the symbol does not have symbol type information at the
evaluation phase. I have a workaround that consist in allocating a constant
expression with the symbol identifier in the parser but then we should check
the datatype manually in the evaluation. I don't like that solution at all.
Is there any other way to accomplish that? I would like to find a better
solution. Thanks!
