* src: rename nftnl_rule_expr to nftnl_exprPablo Neira Ayuso2015-09-071-25/+25
| | | | | | | Use a shorter name for this, morever this can be used from sets so the _rule_ is misleading. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: rename existing functions to use the nftnl_ prefixPablo Neira Ayuso2015-09-071-50/+50
| | | | | | | | | So we can use the nft_* prefix anytime soon for our upcoming higher level library. After this patch, the nft_* symbols become an alias of the nftnl_* symbols. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: restore static array with expression operationsPablo Neira Ayuso2015-03-231-5/+0
| | | | | | | | | | | | | We cannot use __attribute__((constructor)) to register the supported expressions in runtime when the library is statically linked. This lead us to some explicit libnftnl_init() function that needs to be called from the main() function of the client program. This patch reverts 4dd0772 ("expr: use __attribute__((constructor)) to register expression").

* src: split internal.h is smaller filesPablo Neira Ayuso2015-02-171-2/+0
| | | | | | | | | The internal.h file started being a small file with private definitions. Its size has been increasing over time more and more, so let's split this in small header files that map to the corresponding class where the functions belong to.

* src: consolidate XML/JSON exportationPablo Neira Ayuso2014-11-101-25/+8
| | | | | | | | | | | | | | Add new buffer class to consolidate the existing code to export objects in XML/JSON and use it. We save ~700 LOC with this change. The rule and set objects are not yet consolidated. It seems this would require some specific glue code per representation type since lists are arranged differently. This also consolidates the tag names, so we make sure the same are used from XML and JSON by placing them in include/buffer.h. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expr: masq: optional printing of flags attr in snprintf_defaultArturo Borrero2014-10-031-2/+4
| | | | | | | | The flags attribute is optional. Thus we should print only if it was originally set. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expr: add new nft_masq expressionArturo Borrero2014-09-091-0/+208
This patch adds userspace support to nft_masq, the new expression to perform masquerade. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
