* 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.

* set: add support for set mechanism selectionArturo Borrero2014-07-241-0/+2
| | | | | | | | | | This patch adds support to select the set mechanism. The kernel support was added in commit: c50b960 netfilter: nf_tables: implement proper set selection Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expr: log: add support for level and flagsPablo Neira Ayuso2014-07-011-0/+2
| | | | | | This is required by changes scheduled for Linux kernel 3.17. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* set: add set ID supportPablo Neira Ayuso2014-05-192-0/+2
| | | | | | | Add the set ID (u32) which allows us to uniquely identify the set in the batch that is sent to kernel-space. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* 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).

* set_elems: delete unexisting exported symbolArturo Borrero2014-03-261-2/+0
| | | | | | | There is no function called 'nft_set_elem_nlmsg_parse()' Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* rule: add NFT_RULE_ATTR_USERDATA supportPablo Neira Ayuso2014-02-271-0/+1
| | | | | | This allows us to manipulate the user data area of the rule. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add nft_*_attr_{set|get}_data interfacePablo Neira Ayuso2014-02-275-0/+18
| | | | | | | | | | | | This patch adds two functions that allows you to validate the size of the attribute. This new functions provide a replacement for nft_rule_attr_set and nft_rule_attr_get. The data_len parameter was already passed to the {_set|_get} funcion in expressions. For consistency, add nft_rule_expr_{set|get}_data alias. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: early attribute type validation in nft_*_attr_setPablo Neira Ayuso2014-02-274-0/+8
| | | | | | | | This allows us to remove the default case in the switch, which show help to spot missing attribute support since gcc will spot a compilation warning. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* Merge branch 'master' into next-3.14Pablo Neira Ayuso2014-02-032-0/+8
