* include: add missing gen.h to Makefile.amlibnftnl-1.0.3Pablo Neira Ayuso2014-12-161-1/+2

* src: consolidate XML/JSON exportationPablo Neira Ayuso2014-11-102-1/+82
| | | | | | | | | | | | | | 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>

* ruleset: deconstify _get interfaceArturo Borrero2014-10-241-1/+1
| | | | | | | | Having this interface returning a const pointer makes very hard to modificate the content of a chain contained in a nft_ruleset. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add ruleset generation classPablo Neira Ayuso2014-09-192-2/+68
| | | | | | | | | | | | | | The generation object currently only contains the uint32_t that indicates the generation ID. I could have just add the API to return the uint32_t ID instead, but I think this API is easier to extend without adding new APIs. We can probably include meaningful statistics in the generation message in the future without much hassle. This patch also extends examples/nft-events.c.

* src: get rid of cached copies of x_tables.h and xt_LOG.hPablo Neira Ayuso2014-08-313-205/+1
| | | | | | | | | | Keeping the full cached copy the of x_tables.h file in tree is too much for just the XT_EXTENSION_MAXNAMELEN constant. Similarly, xt_LOG.h is not actually required by the tests, we can use any whatever syntetic data to make sure the setter and getter provide the same result. So, let's get rid of these headers from the library tree. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* common: add batching interfacesPablo Neira Ayuso2014-08-141-0/+5
| | | | | | | | | | | | | | This patch adds the following new interfaces: int nft_batch_is_supported(void); void nft_batch_begin(char *buf, uint32_t seq); void nft_batch_end(char *buf, uint32_t seq); Quite likely this is going to be reused by third party applications requiring to put things in the batch. We already have potential clients for this code in nft and iptables-compat. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* set_elem: add nft_set_elems_nlmsg_build_payload_iter()Pablo Neira Ayuso2014-07-251-0/+3
| | | | | | | | | This new interface allows you to put as many set elements as possible into a netlink message. The iterator stores the last element that has fit into a netlink message, so you can continue adding more set elements across several netlink messages.

* src: add flag to add event wrapping in output functionsArturo Borrero2014-04-261-0/+6
| | | | | | | | | | | | | | This patch uses the flag option of each output function to print an event wrapper string in each object. In order to use this functionality, the caller must pass the corresponding flags: NFT_OF_EVENT_NEW / NFT_OF_EVENT_DEL. (I have slightly refactorized the original code to add the xml/json header and footer --pablo).
