* src: xml: cleanup set element parsingPablo Neira Ayuso2013-08-071-3/+4
| | | | | | | | | | | | Move nft_mxml_set_elem_parse to set_elem.c to improve readability, thus, we don't need to jump from set_elem.c to mxml.c to see how the parsing is done. I have also refactored some common parsing code in the new helper function nft_mxml_set_elem_parse, that avoids conversions from XML tree to text and then again back to tree.

* src: xml: delete unneeded XML prefixesArturo Borrero Gonzalez2013-08-071-7/+7
| | | | | | | | | | | | | | | | | | | | This patch changes some XML nodes with prefixes, as the example below ilustrates. Before: <rule> <rule_flags/> <rule_family/> <rule> After: <rule> <flags> <family> </rule> Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* src: remove useless castingPablo Neira Ayuso2013-08-061-9/+4

* src: fully constify nft_*_get functionsPablo Neira Ayuso2013-08-061-1/+1
| | | | | | | | | We have several char * field that were not constify to avoid gcc compilation warnings when calling free. Since (99d2574 src: add xfree and use it), we can fully constify these objects fields without trouble. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add xfree and use itPablo Neira Ayuso2013-08-061-11/+11
| | | | | | | | This patch adds xfree, a replacement of free that accepts const pointers. This helps to remove ugly castings that you usually need to calm down gcc. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: remove version from XML and JSON representationsPablo Neira Ayuso2013-07-261-12/+3
| | | | | | | | | | | | | | | | | | | | | | This patch removes the version XML node and the version JSON field in all our existing objects. The current versioning approach consists of adding a version field to every object representation in XML and JSON. While listing my entire rule-set, one can notice that this approach is too bloated. Once the library enters stable stage, if we need to obsolete a XML node and a JSON field, we can follow this procedure: 1) Remove the XML node and the JSON field from the output, so fresh outputs will not contain the old ones anymore. 2) Do not remove the parsing of the old XML node and the JSON field inmediately. We have to keep supporting the parsing for a while to avoid breaking the interpretion of old XML/JSON files. We can spot a warning to warn about it, so users generate a fresh output again.

* set: xml: change XML attributes to nodes.Arturo Borrero2013-07-261-14/+12
| | | | | | | | | | | | | | | | This patch changes all XML attributes to XML nodes in nft_set. In order to avoid issues regarding XML nodes with the same name but different meanings, I've followed this pattern for the new elements: <set> <set_table>string</set_table> <set_name>string</set_name> [...] </set> Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: constify parameter of nft_*_is_setEric Leblond2013-07-191-1/+1
| | | | | | | | The functions nft_*_attr_is_set() is doing no modification so it is possible to type it to const. Signed-off-by: Eric Leblond <eric@regit.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: simplify getter logicPablo Neira Ayuso2013-07-181-26/+11
| | | | | | | | This patch refactors the getter code to simplify it. The default cases have been removed so gcc will spot a warning if an attribute is not handled appropriately. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add nft_*_list_add_tailPablo Neira Ayuso2013-07-161-1/+7

| | | | | | | | | | | In (dde2039 src: add nft_*_unset functions), I mangled Arturo's patch to add a default case, but he was intentionally not adding it to unset attributes that require no memory releases. I prefered to add the attributes explicitly in the switch rather on failing back on the default action. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
