Subject: [pve-devel] [PATCH pve-firewall v2 21/25] add support for loading sdn firewall configuration
Date: Thu, 10 Oct 2024 17:56:33 +0200 [thread overview]
Message-ID: <20241010155637.255451-22-s.hanreich@proxmox.com> (raw)
In-Reply-To: <20241010155637.255451-1-s.hanreich@proxmox.com>
This also includes support for parsing rules referencing IPSets in the
new SDN scope and generating those IPSets in the firewall.
Loading SDN configuration is optional, since loading it requires root
privileges which we do not have in all call sites. Adding the flag
allows us to selectively load the SDN configuration only where
required and at the same time allows us to only elevate privileges in
the API where absolutely needed.
