* expr: no need to nul-terminate buffer from expression ->snprintf indirectionPablo Neira Ayuso2017-10-041-3/+0
| | | | | | | ->snprintf() is always called via nftnl_expr_snprintf() wrapper, which is already dealing with this corner case for us. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: Buffer is null terminated.Varsha Rao2017-09-271-0/+3
| | | | | | | In _snprintf() functions definition the buffer is null terminated. Signed-off-by: Varsha Rao <rvarsha016@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: Change parameters of SNPRINTF_BUFFER_SIZE macro.Varsha Rao2017-09-271-3/+4
| | | | | | | | | SNPRINTF_BUFFER_SIZE() macro declaration and definition is changed so that it accepts three arguments ret, remain and offset. Parameters size and len are not required instead parameter remain keeps track of available space in the buffer. Signed-off-by: Varsha Rao <rvarsha016@gmail.com>
* src: remove libmxml supportArturo Borrero2016-09-231-18/+0
| | | | | | | | | | | | | | | | | | | This patch removes the libmxml integration in libnftnl, since we have JSON in place and there is no need to support two at the same time. The JSON support is much better, for example libjansson has a better parsing error reporting. Moreover, libmxml 2.10 breaks the integration with libnftnl somehow, as reported in Debian bug #83870 [0]. Also, the XML support inside libnftnl has never been in good shape, with several tiny inconsitencies.

* src: Implement rule comparisonCarlos Falgueras García2016-08-171-0/+14
| | | | | | | | | | | | | | | | | | | | This patch implements the function: bool nftnl_rule_cmp(const struct nftnl_rule *r1, const struct nftnl_rule *r2) for rule comparison. Expressions within rules need to be compared, so also has been created the function: bool nftnl_expr_cmp(const struct nftnl_expr *e1, const struct nftnl_expr *e2); Also includes all expression comparators.

* libnftnl: constify object arguments to various functionsPatrick McHardy2016-05-091-5/+7
| | | | | | | | | flow table support needs constant object arguments to printing functions to avoid ugly casts. While at it, also constify object arguments to message construction, destructor and a few helper functions.
