The netfilter.org "libnfnetlink" project
libnfnetlink is the low-level library
for netfilter related kernel/userspace communication. It provides a generic
messaging infrastructure for in-kernel netfilter subsystems (such as
nfnetlink_log,
nfnetlink_queue,
nfnetlink_conntrack) and their
respective users and/or management tools in userspace.
This library is not meant as a public API for application developers. It is only
used by other netfilter.org projects, such as
libnetfilter_log,
libnetfilter_queue or
libnetfilter_conntrack.
libnfnetlink requires and a kernel that features the
nfnetlink subsystem. This includes all 2.6.x kernels >= 2.6.14.
- low-level nfnetlink message processing functions
libnfnetlink was mostly written by the netfilter core
team, with some contributions from Pablo Neira Ayuso.
