* src: add fprintf API functionsArturo Borrero2013-11-031-0/+27
| | | | | | | | | | | | | | Now it's possible to print directly from libnftables to a file or other stream. The caller must explicitly print the trailing '\n' in this call. The error reporting of fprintf (< 0) is respected. However, we have already print some information in case that the default (plain text) output is used, that output is mostly intended for debugging so it should not be a problem.

* utils: fix error path for nft_strtoiArturo Borrero2013-08-201-3/+4
| | | | | | | | If the return of nft_get_value() is not evaluated, we don't know if the parsed value is between the limits of its type. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add xfree and use itPablo Neira Ayuso2013-08-061-0/+5
| | | | | | | | 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: utils: add verdict2str and use itArturo Borrero2013-07-251-0/+37
| | | | | | | | | | | | 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. Introduced in (51370f0 src: add support for XML parsing). Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: xml: consolidate common XML code via nft_mxml_num_parseArturo Borrero2013-07-251-0/+73
| | | | | | | | | | | This patch moves common XML parsing code to nft_mxml_num_parse(). To handle this, the nft_strtoi() helper fuction is included. I've changed some MXML_DESCEND[_FIRST] flags to avoid match a nested node under some circumstances, ie, matching two nodes with the same name that are descendant.
