* ebtables-compat: include /etc/ethertypes in tarballArturo Borrero2015-01-071-0/+39
| | | | | | | | | The /etc/ethertypes file was originally distributed by the ebtables tarball. So, let's include the file also in ebtables-compat, so users can keep using protocol names instead of the hex code.

* xtables: bootstrap ARP compatibility layer for nftablesGiuseppe Longo2013-12-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch bootstraps ARP support for the compatibility layer: 1) copy original arptables code into xtables-arp.c 2) adapt it to fit into the existing nft infrastructure. 3) add the builtin table/chains for ARP. 4) add necessary parts so xtables-multi can provide xtables-arp. 5) add basic support for rule addition (-A), insertion (-I) and listing (-L). [ This was originally posted in a series of patches with interdependencies that I have collapsed to leave the repository in consistent state. This patch includes the following changes I made: * Rename from xtables-arptables to xtables-arp, previous name too long. * Remove nft-arptables.c, now we have one single nft-arp.c file. Moved specific ARP functions to nft.c. Those should go away at some point as some refactorization should allow to accomodate those functions to the existing infrastructure. * Fix --opcode Request/Reply, so we can do something useful with this like dropping ARP request/replies. --pablo ] Signed-off-by: Giuseppe Longo <giuseppelng@gmail.com> Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* use nf_tables and nf_tables compatibility interfacePablo Neira Ayuso2013-12-301-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following utilities: * xtables * xtables-restore * xtables-save * xtables-config They all use Patrick's nf_tables infrastructure plus my compatibility layer. xtables, xtables-restore and xtables-save are syntax compatible with ip[6]tables, ip[6]tables-restore and ip[6]tables-save. Semantics aims to be similar, still the main exception is that there is no commit operation. Thus, we incrementally add/delete rules without entire table locking. The following options are also not yet implemented: -Z (this requires adding expr->ops->reset(...) so nft_counters can reset internal state of expressions while dumping it) -R and -E (this requires adding this feature to nf_tables) -f (can be implemented with expressions: payload 6 (2-bytes) + bitwise a&b^!b + cmp neq 0) -IPv6 support. But those are a matter of time to get them done. A new utility, xtables-config, is available to register tables and chains. By default there is a configuration file that adds backward compatible tables and chains under iptables/etc/xtables.conf. You have to call this utility first to register tables and chains. However, it would be possible to automagically register tables and chains while using xtables and xtables-restore to get similar operation than with iptables.

* extensions: libxt_connlabel: use libnetfilter_conntrackFlorian Westphal2013-07-161-8/+0
| | | | | | | | | | | | | | | | | Pablo suggested to make it depend on lnf-conntrack, and get rid of the example config file as well. The problem is that the file must be in a fixed path, /etc/xtables/connlabel.conf, else userspace needs to "guess-the-right-file" when translating names to their bit values (and vice versa). Originally "make install" did put an example file into /etc/xtables/, but distributors complained about iptables ignoring the sysconfdir. So rather remove the example file, the man-page explains the format, and connlabels are inherently system-specific anyway. Signed-off-by: Florian Westphal <fw@strlen.de>
* extensions: add connlabel matchFlorian Westphal2013-05-061-0/+8
allows to "tag" connections with up to 128 label names. Labels are defined in /etc/xtables/connlabel.conf, example: 0 from eth0 1 via eth0 Labels can then be attached to flows, e.g. -A PREROUTING -i eth0 -m connlabel --label "from eth0" --set Signed-off-by: Florian Westphal <fw@strlen.de>
