* Add support for user-defined symbolic constantsPatrick McHardy2009-03-201-0/+2
| | | | | | | | | | | | | | | | | | User-defined constants can be used like this: define allowed_hosts = { 192.168.0.0/24, 10.0.0.20-10.0.0.30 } define udp_services = domain define tcp_services = { ssh, domain } ip saddr $allowed_hosts udp dport $udp_services counter accept ip saddr $allowed_hosts tcp dport $tcp_services counter accept Recursive definitions are possible, but currently not fully handled. Anything requiring transformations (sets using ranges) can not be used more than once currently since the expressions need to be COW'ed previously. Signed-off-by: Patrick McHardy <kaber@trash.net>
