"When it comes to integrating nftables support into firewall-managing applications such as firewalld, in the past developers were presented with merely two options: either using the very low-level nftnl library or calling 'nft' utility and parsing its output. The latter is disapproved by the maintainer since 'nft' utility really is designed for human interaction. Making use of libnftnl on the other hand will lead to partial reimplementation of 'nft' utility internals - so not really an alternative either.

A new library named libnftables aims to solve this. The presenter will give an overview of past, current and future development as well as a status report of integration into firewalld as alternative backend to the previous combination of iptables, ebtables and ipset."
