A stable release of the interface for simplifying network parameter settings has been published — NetworkManager 1.54.0. Plugins for supporting VPNs (Libreswan, OpenConnect, Openswan, SSTP, etc.) are being developed within their own development cycles.
Key innovations in NetworkManager 1.54:
- Added the ability to attach separate IPv4 packet forwarding settings to devices using the 'ipv4.forwarding' option.
- A 'prefix-delegation' setting has been added, allowing the use of the 'subnet-id' property to choose a subnet on the lower network interface when using IPv6 prefix delegation.
- The nm-cloud-setup utility now supports configuring network interfaces on bare metal servers in OCI (Oracle Cloud Infrastructure).
- When activating connections based on VPN WireGuard, the addition of rules to the packet filter has been implemented to prevent the kernel from dropping incoming packets due to rp_filter (Reverse Path Filter).
- The nmtui utility now allows the configuration of the loopback interface.
- It is now possible to reassign most properties of ovs-bridge and ovs-port on the fly without disconnecting the connection.
- Added the 'sriov.preserve-on-down' property, which manages the preservation of SR-IOV (Single Root I/O Virtualization) settings when a connection is deactivated. You can choose to preserve the settings or reset them to their default values.
- The 'ovs-dpdk.lsc-interrupt' property has been added for configuring the Link State Change (LSC) detection mode for OVS DPDK network interfaces.
- The initrd-generator now parses the NBFT (NVMe Boot Firmware Table) boot tables for network configuration during the early boot phase.
- Systemd services have been added for network configuration at the initial RAM disk (initrd) level.
