Library for interfacing with Netfilter (kernel)

nfnetlink is a netlink(7) based kernel/userspace transport layer. It
provides a unified kernel/userspace interface for the various
netfilter subsystems, such as connection tracking, logging and
queueing.

libnfnetlink is a userspace library that provides some low-level
nfnetlink handling functions. It is used as a foundation for other,
netfilter subsystem specific libraries such as
libnfnetlink_conntrack, libnfnetlink_log and libnfnetlink_queue.
