* expr: fix concat expression type propagationPatrick McHardy2013-04-181-0/+37
| | | | | Dynamically instantiate a data type to represent all types of a concatenation and use that for type propagation.
* types: add ethernet address typePatrick McHardy2013-04-181-0/+1
| | | | | | | | Add a new type for ethernet addresses. This is needed since for concatenations we need fixed sized data types, the generic link layer address doesn't have a fixed length. Signed-off-by: Patrick McHardy <kaber@trash.net>
* datatype: parse/print in all basetypes subsequentlyPatrick McHardy2013-04-181-9/+15
| | | | | | | | Go down the chain of basetypes until we find a ->parse()/->print() callback or symbol table. Needed to invoke the generic link layer address parsing function for the etheraddr_type. Signed-off-by: Patrick McHardy <kaber@trash.net>

* netlink: fix byteorder of RHS of relational meta expressionPatrick McHardy2010-07-061-0/+1
| | | | | | | The RHS needs to be postprocessed before updating the payload context for byteorder conversion. Fixes iiftype match reconstruction. Signed-off-by: Patrick McHardy <kaber@trash.net>
* expressions: kill seperate sym_type datatype for symbolsPatrick McHardy2009-04-011-6/+6

* datatype: add/move size and byte order information into data typesPatrick McHardy2009-03-311-9/+20
| | | | | | | | | | Add size and type information to non-basetype types and remove the now redundant information from the symbol tables. This will be used to determine size and byteorder of set members without analyzing the ruleset for incremental update operations. Signed-off-by: Patrick McHardy <kaber@trash.net>
* datatype: maintain table of all datatypes and add registration/lookup functionPatrick McHardy2009-03-311-10/+65
| | | | | | | | | | | Add a table containing all available datatypes and registration/lookup functions. This will be used to associate a stand-alone set in the kernel with the correct type without parsing the entire ruleset. Additionally it would now be possible to remove the global declarations for the core types. Not done yet though. Signed-off-by: Patrick McHardy <kaber@trash.net>
