From 6510a98f4139f112a0c76c71ff889ef93eac41fb Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 6 Nov 2012 17:06:39 +0100 Subject: api: add connlabel api and attribute adds new labelmap api to create a name <-> bit mapping from a text file (default: /etc/xtables/connlabel.conf). nfct_labelmap_new(filename) is used to create the map, nfct_labelmap_destroy() releases the resources allocated for the map. Two functions are added to make map lookups: nfct_labelmap_get_name(map, bit) returns the name of a bit, nfct_labelmap_get_bit returns the bit associated with a name. The connlabel attribute is represented by a nfct_bitmask object, the nfct_bitmask api can be used to test/set/get individual bits ("labels"). The exisiting nfct_attr_get/set interfaces can be used to read or replace the existing labels associated with a conntrack with a new set.
