* src: move callbacks to run.c for better readabilityPablo Neira Ayuso2008-11-271-1/+1
| | | | | | | | | This patch is a cleanup. It moves the callbacks from netlink.c to run.c where they are actually invoked. This is better for code readability as I usually have to switch from run.c to netlink.c to remember what the callbacks actually do. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* filter: CIDR-based filtering supportPablo Neira Ayuso2008-11-251-1/+14
| | | | | | | | | | This patch adds CIDR-based filtering support. The current implementation is O(n). This patch also introduces the vector data type which is used to store the IP address and the network mask. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* Major rework of the user-space event filteringPablo Neira Ayuso2008-07-221-0/+31
This patch reworks the user-space filtering. Although we have kernel-space filtering since Linux kernel >= 2.6.26, we keep userspace filtering to ensure backward compatibility. Moreover, this patch prepares the implementation of the kernel-space filtering via libnetfilter_conntrack's high-level berkeley socket filter API.
