parser: evaluate commands immediately after parsing
We currently do parsing and evaluation in two seperate stages. This means that if any error occurs during parsing, we won't evaluate the syntactical correct commands and detect possible evaluation errors in them. In order to improve error reporting, change this to evaluate every command as soon as it is fully parsed. With this in place, the ruleset can be fully validated and all errors reported in one step: tests/error.1:6:23-23: Error: syntax error, unexpected newline filter input tcp dport ^ tests/error.1:7:24-26: Error: datatype mismatch, expected internet network service, expression has type Internet protocol filter input tcp dport tcp ~~~~~~~~~ ^^^ tests/error.1:8:24-32: Error: Right hand side of relational expression (==) must be constant filter input tcp dport tcp dport ~~~~~~~~~~^^^^^^^^^ Signed-off-by: Patrick McHardy <>
