* src: xml: use nodes instead of attributesArturo Borrero Gonzalez2013-08-0664-166/+379
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When working with XML, it's desirable to work with nodes better than attributes. Table/chain/rules had attributes in their XML representation, and this patch transform those to nodes, ie: Before: <table name="filter"> <family>ip</family> <table_flags>0</table_flags> </table> After: <table> <name>filter</name> <family>ip</family> <table_flags>0</table_flags> </table> While at it: * There was a lot of redundant code that is now collapsed with the new nft_mxml_family_parse() helper function. * I've added a small fix: additional validation for the name of the current XML object, and also replace raw strtol calls to nft_strtoi. * Also, all XML testfiles are updated to keep passing the parsing tests and mantain the repo in consisten state.

* src: fully constify nft_*_get functionsPablo Neira Ayuso2013-08-068-14/+14
| | | | | | | | | 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 Ayuso2013-08-0614-67/+74
| | | | | | | | 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>
* chain: Use nft_str2hooknum() in the XML parsing code.Arturo Borrero Gonzalez2013-08-051-15/+11
| | | | | | | Note: I've used MXML_DESCEND_FIRST flag when calling nft_mxml_str_parse() to ensure that the parsing travels from the top of the chain XML tree. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com>
* chain: fix compilation warning due to unused nft_str2hooknum()Arturo Borrero Gonzalez2013-08-051-1/+1
| | | | | | | | If neither XML_PARSING nor JSON_PARSING are defined (libnftables configured without XML/JSON parsing support), a warning is produced due to unused nft_str2hooknum() function. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com>
* src: xml: table/chain delete propertiesArturo Borrero Gonzalez2013-08-057-60/+35
| | | | | | | | | | This patch deletes the <properties> node in chain and table XML objects. For this to work, the first tree search with MXML_DESCEND_FIRST flag is moved to the next node.

* src: remove version from XML and JSON representationsPablo Neira Ayuso2013-07-2667-146/+73
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | This patch changes all XML attributes to XML nodes in nft_set.

* tests: xml: add realistic XML tests filesArturo Borrero2013-07-2552-120/+1295
| | | | | | | | | | | | | | | | | | | | This patch refresh current XML testfiles with some realworld expressions extracted from rules. The nft instruction itself is added as a comment for future references. All XMl files are now indented with tabs instead of spaces. Also, a bunch of new realworld rules with mixed expressions are added. I used this command to get the XML formatted with tabs: $ export XMLLINT_INDENT=$'\t' $ xmllint --format file.xml The xmllint tool is included in the libxml2-utils package (at least on debian systems).

| | | | | | | | | | | | Add verdict2str() and str2verdict() helper functions and use in XML. While at it, I've fixed a small style issue in the data_reg JSON output and a bug in the data_reg XML parser: The parser walked the top level tree, instead of single <data_reg> node.
