Subject: [PATCH 0/2] services: nftables: Make it extandable
Date: Mon, 12 Jul 2021 23:05:43 +0200

This patchset make "nftables-service-type" extendable, so other services could
open port.  I wrote this to be able to use libvirt with nftables (another
patch is comming about that) like this:

--8<---------------cut here---------------start------------->8---
(simple-service 'nftables-libvirt nftables-service-type
                   (list "# Libvirt?
add rule inet guix forward ct state established,related accept
add rule inet guix forward iifname \"virbr*\" accept

add chain inet guix libvirt
insert rule inet guix input iifname \"virbr*\" jump libvirt
insert rule inet guix libvirt udp dport 53 accept
insert rule inet guix libvirt tcp dport 53 accept
insert rule inet guix libvirt udp dport 67 accept
"))
--8<---------------cut here---------------end--------------->8---

So this should make it possible to implement Solene's
"simple-firewall-service"¹ by simply extending "nftables-service-type".

Also, now, stopping nftables only remove the "guix" table so other software
can use their own namespaces without being purged when that service is
stopped.

WDYT?
