    Wasn't there some discussion on lkml some time ago that the future is eBPF and XDP, and that nftables is a failed experiment with little usage? And somebody had created some kind of iptables implementation that in fact compiled the rules to eBPF (bpfilter). But subsequently I've heard little of it, and it seems that distros are slowly starting to switch over to nftables. What gives?

    Nice.

    It is long overdue for nftables to get some wider adoption.

    They rushed it because otherwise, they would be stuck with iptables for the whole RHEL 8 life cycle.

    From the RHEL 8 release notes section 5.1.14:

    * "nftables replaces iptables as the default network packet filtering framework"

    * "firewalld uses nftables by default"

    As can be found here:

    While Fedora 31 isn't even out yet, looking ahead to the Fedora 32 release next spring is a plan to switch firewalld as Fedora's default network firewall from its existing iptables back-end to the more modern nftables back-end...
