* conntrack: add nfct_set_attr_l and ATTR_HELPER_INFOPablo Neira Ayuso2012-06-261-0/+12
| | | | | | | | | | | | | | This adds the ATTR_HELPER_INFO that can be used to send binary data that will be attached to the conntrack. This is useful for the user-space connection tracking support. This patch also adds a new interface: nfct_set_attr_l(attr, type, value, length); that is used to set the variable length helper information. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expect: add new API to build/parse ctnetlink messages using libmnlPablo Neira Ayuso2012-05-261-1/+1
| | | | | | | | This patch adds support to build and to parse netlink messages from/to one user-space nf_conntrack object. It uses libmnl, thus libnetfilter_conntrack now depends on this library. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* conntrack: add new API to build/parse ctnetlink messages using libmnlPablo Neira Ayuso2012-05-261-0/+934
This patch adds support to build and to parse netlink messages from/to one user-space nf_conntrack object. It uses libmnl, thus libnetfilter_conntrack now depends on this library. This is the first patch in the direction of removing the dependency on the veteran libnfnetlink. I have decided to update LIBVERSION in this patch. I know it's recommended to do this before releasing the software. I prefer to do this so snapshot packages get the correct LIBVERSION. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
