* examples: nft-events: use new events wrappersArturo Borrero2014-04-261-15/+31
| | | | | | | Let's use the new event wrappers in the events example. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: complete nft-events exampleArturo Borrero2014-04-071-0/+60
| | | | | | | | Complete nft-events example by adding a basic set & set_elem event notification. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: remove nft-rule-insert from Makefile.amPablo Neira Ayuso2014-03-281-3/+0
| | | | | | This example doesn't exist anymore. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: nft-rule-del: removed printf rule functionÁlvaro Neira Ayuso2014-03-081-4/+0
| | | | | | | | | | | | | Removed this code because with that we have a strange output. Example: we have a rule with handle 4 and we execute nft-rule-del ip filter input 4 Output: unknown filter input 4 0 Signed-off-by: Alvaro Neira Ayuso <alvaroneay@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: nft-rule-insert: fix and merge it to nft-rule-addÁlvaro Neira Ayuso2014-03-083-208/+12
| | | | | | | | Merged the example for inserting rules and fixed for using the correct header. Signed-off-by: Alvaro Neira Ayuso <alvaroneay@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: nft-rule-del: fix missing batching headersÁlvaro Neira Ayuso2014-03-081-4/+39
| | | | | | | | | Fix the example for deleting rules. Before this patch, the program tried to delete the rule without using the correct header. Signed-off-by: Alvaro Neira Ayuso <alvaroneay@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: check if netlink parsing failsArturo Borrero2014-02-271-1/+2
| | | | | | | | We have to check if mnl_attr_parse() returns an error, which means that it failed to validate and retrieve the attributes. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* example: nft-rule-add: simplify examplePablo Neira Ayuso2014-02-271-57/+29
| | | | | | The nft_mnl_batch_talk() is overly complicated for a simple example that just adds one single rule. Simplify this to prepare the merge of nft-rule-insert, which looks very similar.
* Merge branch 'master' into next-3.14Pablo Neira Ayuso2014-02-0327-189/+283
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes changes to adapt this branch to the library rename that happened in the master branch.

| * rename library to libnftnllibnftnl-1.0.0Pablo Neira Ayuso2014-01-2026-59/+59
| | | | | | | | | | | | We plan to use this library name for the higher layer library. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * src: new error reporting approach for XML/JSON parsersÁlvaro Neira Ayuso2014-01-067-14/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I have added a new structure for reporting some errors in parser that we can't cover with errno. In this patch, we have three errors that we can't cover with errno: NFT_PARSE_EBADINPUT : Bad XML/JSON format in the input NFT_PARSE_EMISSINGNODE : Missing node in our input NFT_PARSE_EBADTYPE : Wrong type value in a node Signed-off-by: Alvaro Neira Ayuso <alvaroneay@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
| * examples: nft-rule-add: use existing batch infrastructurePablo Neira Ayuso2013-12-101-110/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the existing example to add the rule: nft add rule ip filter input tcp dport 22 counter It uses the existing nfnl batching approach using the generic mnl netlink message batching infrastructure. It also removed the code that uses xtables compat code. Based on original patch by Arturo Borrero Gonzalez. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* | examples: add nft-ruleset-getArturo Borrero2014-01-042-0/+393
| | | | | | | | | | | | | | | | | | | | This example prints the ruleset, using the ruleset API of nftables. The kernel patch c9c8e48 ("netfilter: nf_tables: dump sets in all existing families") is required. Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* | examples: nft-set-get: retrieve all sets via unspecArturo Borrero2014-01-041-1/+3
|/ | | | | | | | Other nftables objects are allowed to be dumped with NFPROTO_UNSPEC. With sets is also possible since kernel patch c9c8e48 ("netfilter: nf_tables: dump sets in all existing families"). Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com>
* src: unify parse and output typesÁlvaro Neira Ayuso2013-11-1413-32/+32
| | | | | | | | | Unify parse and output types that are redundant to all existing nftables objects. Thus, all NFT_*_O_[XML|JSON|DEFAULT] are merged into NFT_OUTPUT_[JSON|XML] and NFT_PARSE_[JSON|XML].

* examples: nft-set-get: retrieve all sets per familyPablo Neira Ayuso2013-09-241-5/+6
| | | | | | | | | | | Likewise other nftables objects, this patch allows you to dump the sets per family. This is possible since kernel changes (netfilter: nf_tables: allow to dump all existing sets), we can get the full list of sets per family. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* examples: nft-chain-add: allow to create custom chainsPablo Neira Ayuso2013-07-181-18/+23
| | | | | | | So far, it was only possible to create base chains. This patch allows you to create custom chains as well. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | | | | | | | | | Thus, automodule loading was not working. While at it, apply not so relevant comestic cleanups and fix some inconsistencies between examples. * Fix copyright header, this is code heavily based on existing nft-*-add examples. * Remove unrequired extern struct nft_table definition. * Make sure we close file descriptor once we don't need it anymore. * Remove unrequired casting. * Remove comment that provides nothing interesting. I considered a patch to address each on those was too much burden. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* examples: remove LIBXML_LIBS from LDADDPablo Neira Ayuso2013-07-101-21/+21
| | | | | | | | Remove it from the example files, we don't need it. There is no explicit reference to any of the libmxml functions in those files, so the linker does not need that library. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

To use it: $ cd test/ $ make nft-parsing-test $ ./nft-parsing-test xmlfiles/ This testbench supersedes old .sh test scripts, so they are deleted.
