NetworkManager-1.52
Overview of changes since NetworkManager-1.50
=============================================
This is a snapshot of NetworkManager development. The API is
subject to change and not guaranteed to be compatible with
the later release.
USE AT YOUR OWN RISK. NOT RECOMMENDED FOR PRODUCTION USE!
* Store interactive history in `$XDG_CACHE_HOME/nmcli-history` instead of
`~/.nmcli-history`
* Add new ipv4.link-local=fallback to set an IPv4 link-local address
when no other IPv4 is set.
* Remove support for building with Autotools
* Add IPVLAN interface support
* Allow to manually configure the authentication of LTE's initial EPS Bearer.
* Add support for the "IPv6-only preferred" DHCPv4 option (RFC 8925),
used to indicate that a host supports an IPv6-only mode and is
willing to forgo obtaining an IPv4 address if the network provides
IPv6 connectivity.
* Support automatically adding routes to DNS servers via the
ipv4.routed-dns and ipv6.routed-dns properties; when enabled, each
name server is reached only via the device that specifies it.
* Support OCI in nm-cloud-setup
* Added support for ethtool FEC mode
* Add new ipv4.shared-dhcp-range and ipv4.shared-dhcp-lease-time,
which allows you to customize the DHCP range and lease time offered
by DHCP server in `shared` connection method.
* DNS servers can now be specified with a URI-like syntax which supports
DNS over TLS name servers.
* The initrd-generator understands the "rd.net.dns" option to configure
global name servers.
* Drop support for the "dhcpcanon" DHCP client.
* global-dns configuration section now has 2 additional keys: "resolve-mode"
and "certification-authority".
* Dnsconfd plugin can now be used for configuration of system-wide DNS
caching resolver. If dnsconfd plugin is enabled and ipvX.routed-dns is
set to -1 then adding routes is by default enabled.
=============================================
NetworkManager-1.50
Overview of changes since NetworkManager-1.48
=============================================
* The support for "dhclient" has been deprecated, not built unless
explicitely enabled, and will be removed in a future release.
The internal DHCP client should be used instead and has been
the default since version 1.20 (1.12 when built with meson).
* Support matching a OVS system interface by MAC address.
* Add a timeout option to connectivity checking.
* Support configuring veth interfaces in nmtui.
* When looking up the system hostname from the reverse DNS lookup of
addresses configured on interfaces, NetworkManager now takes into
account the content of /etc/hosts.
* Revert to using sysctl ipv6.conf.default for ip6-privacy
* Allow specifying a system OVS interface by MAC address
* ndisc: Support multiple gateways for a single network
* wifi: Support configuring channel-width in AP mode
* keyfile: Stop writing offensive terms into keyfiles
* Support reapplying the VLANs on bridge ports.
* Fix crash caused by malformed LLDP package if debug log is enabled
* Retry hostname resolution when it fails
=============================================
NetworkManager-1.48
Overview of changes since NetworkManager-1.46
=============================================
* Building with autotools is now deprecated and will be completely removed
in the next development cycle. We recommend using meson to build
NetworkManager -- for basic setup, see the CONTRIBUTING.md file.
To ignore this deprecation and still build with Autotools, you can specify
the '--disable-autotools-deprecation' argument when configuring.
* Support changing the OpenSSL ciphers for 802.1X authentication via
connection property "802-1x.openssl-ciphers".
* The reason why a device is unmanaged is now properly set in the
"StateReason" property of the "Device" D-Bus object. The property is
visible in nmcli via "nmcli -f all device show $DEV".
* Deprecated 802-11-wireless and 802-11-wired property 'mac-address-blacklist'
and introduced the 'mac-address-denylist' property.
* Properly restore in-memory connection profiles during the rollback
of a checkpoint.
* Fix detection of 6 GHz band capability for WiFi devices
* Allow IPv6 SLAAC and static IPv6 DNS server assignment for modem broadband
when IPv6 device address was not explicitly passed on by ModemManager
* Fix a performance issue that was leading to 100% CPU usage by NetworkManager
if external programs were doing a big amount of routes updates.
* Patch-level development releases (i.e. 1.48.1-dev) won't be used anymore.
From now on, all the patch releases whithin a stable branch will be normal
releases, like 1.48.0, 1.48.1, 1.48.2, 1.48.3 and so on.
Odd numbers in the minor version number still indicates if it's a development
branch like 1.49 or a stable one like 1.48.
=============================================
NetworkManager-1.46
Overview of changes since NetworkManager-1.44
=============================================
* Support dynamic value "${NETWORK_SSID}" for connection.stable-id to generate
the stable ID based on the Wi-Fi's SSID.
* Support new value "wifi.cloned-mac-address=stable-ssid" for randomizing the
MAC address based on the Wi-Fi network.
* Change internal ABI of NMSetting types and NMSimpleConnection. The layout of
these structs was already hidden from public headers since 1.34 and this change
should not be noticeable.
* Honor udev property ID_NET_AUTO_LINK_LOCAL_ONLY=1 for enabling
link local addresses on default wired connection.
* Honor udev property ID_NET_MANAGED_BY to only manage an interface
when set to "org.freedesktop.NetworkManager".
* D-Bus methods StartFind() and StopFind() on interface
"org.freedesktop.NetworkManager.Device.WifiP2P" now require the
"org.freedesktop.NetworkManager.wifi.scan" Polkit permission.
* Drop build support with Python2. Python3 is now required.
* nmcli: limit number of printed addresses/routes in `nmcli` overview to 10.
* Limit number of exported IP addresses/routes on D-Bus to 100 to reduce
performance cost. Also, D-Bus updates for addresses/routes are now rate
limited to 3 per second.
* cloud-setup: enable more sandboxing options in systemd service file.
* nmcli: show WiFi bandwidth.
* Internal improvements and bugfixes.
* Man page now show the format and accepted values of all properties.
* Added the 'dns-change' dispatcher event.
* Show WiFi devices capability to work on the 6GHz band.
* Allow to set dhcp-client-id to none.
* Support configuring ethtool channels property to configure NIC multiqueue.
* Don't attempt to use IPv6 if it's disabled in kernel.
* Fix handling of OVS interfaces with netdev datapath and cloned MAC.
* Support for old systemd has been droped, at least systemd v200 is required.
* Support Ethtool EEE (Energy Efficient Ethernet) settings.
* Add options to prevent edns0 and trust-ad being automatically added to DNS
configuration.
* Implement fwmark property for IP tunnels.
* Add support to HSR/PRP interfaces.
* Deprecated connection.* properties master, slave-type, autoconnect-slaves
* Allow configuring static routes also when addresses is empty.
* VPN: accept pref-src for IPv6 routes from VPN plugins.
* nmcli: show global metered state.
* Support modifying the DSCP header field for DHCP packets, and change the
default to CS0.
* Enable IPv4 DAD (Duplicate Address Detection) by default.
* vpn: support 2FA authentication from VPN plugins.
* nmtui: allow adding a bond as bridge port.
* sriov: add support to configure the NIC's eswitch settings via Devlink.
* ndisc: fix IPv6 address lifetimes computation.
* Support the MACsec offload mode.
* Support creating generic devices via external "device-handler" dispatcher.
* Documentation improvements.
* Many internal improvements and bug fixes.
=============================================
NetworkManager-1.44
Overview of changes since NetworkManager-1.42
=============================================
* Introduce a new "link" setting that holds properties related to the
kernel link such as "tx-queue-length", "gso-max-size",
"gso-max-segments", "gro-max-size".
* Support sending a DHCPv6 prefix delegation hint via the
"ipv6.dhcp-pd-hint" connection property.
* Support new bond options: "arp_missed_max", "lacp_active",
"ns_ip6_target".
* Add new "initial-eps-bearer-configure" and "initial-eps-bearer-apn"
properties in the GSM setting.
* Setting "connection.stable-id=default${CONNECTION}" changed behavior to
be identical to the built-in default value when the stable-id is not set.
* Add a "[keyfile].rename" option to NetworkManager.conf to force renaming
profiles on disk when their name changes.
* The ifcfg-rh plugin is deprecated; it will only receive bugfixes and
no new features. A warning is emitted the log when a connection in
ifcfg-rh format is found.
* To automatically migrate existing ifcfg-rh connections to the
keyfile format, a new configuration option "main.migrate-ifcfg-rh"
is provided. Migration is disabled by default, but the default value
can be changed at build time via
"--with-config-migrate-ifcfg-rh-default=yes".
* When configuring hostnames in non-public TLD (like "example.local"), use
the TLD as default search domain instead of the full hostname.
* Always apply DNS options from the [global-dns] configuration section
* The NetworkManager daemon now acquires the D-Bus name only after
populating the D-Bus tree. This can add a delay during startup but
it is required to avoid race conditions with other services
depending on NM.
* Add a "version-id" argument to the Update2() D-Bus call to guard
against concurrent modifications of profiles.
* Don't use tentative IPv6 addresses to resolve the system hostname
via DNS.
* Track the number of autoconnect retries left for each device and
connection. Previously it was tracked only per connection and this
lead to unexpected behaviors in case of multiconnect profiles.
* Set VLAN filtering options on bridge via netlink instead of sysfs.
* nm-cloud-setup now supports IMDSv2 on Amazon EC2.
* nmtui now allows to enable or disable Wi-Fi and WWAN radios.
* Honor ignore-carrier=no for bond/bridge/team devices.
* Add version mismatch warning when running nmcli commands.
The following changes were backported to 1.42.x releases between 1.42.0
and 1.42.8, and are also present in NetworkManager-1.44:
- 1.42.8
* Support compiling against pppd 2.5.0.
* Support the "prio" option for bond ports.
* Better handle non-full-membership PKEY_ID with new PKEY_ID_NM
variable in ifcfg-rh files.
- 1.42.2
* Add new "ipv[46].replace-local-rule" connection property that allows
users to remove the autogenerated local route rule. By default,
NetworkManager won't touch the local route rule.
* Introduce a new D-Bus property "Controller" in the ActiveConnection
object, and deprecated the existing "Master" property.
=============================================
NetworkManager-1.42
Overview of changes since NetworkManager-1.40
=============================================
* Added support for source load balancing for Ethernet Bonds.
* Allow specifying vhost name (SNI) for a manually DNS-over-TLS server.
Only works with systemd-resolved plugin.
* Connections can now be activated on a loopback interface.
* Added support of IPv4 ECMP routes. The ECMP routes will get merged
automatically but the user need to configure them as single-hop routes
specifying a valid weight.
* Add new "reapply" dispatcher event.
* Added support of VTI and VTI6 ip-tunnels along with a new property,
"ip-tunnel.fwmark".
* VLAN can now support 802.1ad tagging instead of 802.1Q.
* Invocations of iptables now use "--wait 2" to handle races with concurrent
calls. This fixes misbehavior with IPv4 shared mode.
* The DHCP client-id and DHCPv6 DUID are now exposed along with the lease
information.
* Optionally suppress adding direct route to an external VPN gateway
with the new "ipv[46].auto-route-ext-gw" property.
* Open vSwitch support gained new properties: "ovs-dpdk.n-rxq-desc",
"ovs-dpdk.n-txq-desc", "ovs-interface.ofport-request" and
"ovs-port.trunks".
* Added support of "other_config" for OVS bridge, port or interface. This
property is not supported by nmcli.
* nmtui now supports editing Wi-Fi WPA-Enterprise, Ethernet with 802.1X
authentication and MACsec connection profiles.
* nmcli now allows changing "connection.uuid" and "connection.type"
properties in offline mode and setting the UUID when creating a
connection.
* nmcli now accepts abbreviations for the UUID with the connection selector
in `nmcli connection $operator uuid $uuid`.
* DHCPv6 leases are now declined when addresses fail DAD.
* Documentation improvements.
* Many internal improvements and bug fixes.
The following changes were backported to 1.40.x releases between 1.40.0
and 1.40.10 are also present in NetworkManager-1.42:
- 1.40.10
* Fix the evaluation of the autoconnect retries.
* nm-cloud-setup now preserves addresses added externally.
* Ensure that dnsmasq is stopped after changing the dns backend and
restarting the service.
* Fix honoring an explicit DHCPv6 DUID with dhclient.
* Other various fixes.
- 1.40.8
* Fixed a bug that caused devices (MACsec in particular) to be stuck in
UNAVAILABLE state and not transition to DISCONNECTED if the carrier was
ready too early.
* Improved interoperability of MACsec with some Aruba switches by allowing
CKN shorter than 64 characters.
* Fixed an assertion failure when restarting NetworkManager with MACsec
links configured.
* Fixed a possible DHCP helper crash when handling failure to connect to
D-Bus.
* Corrected calculation of expiration time for items configured from IPv6
neighbor discovery messages.
* Various fixes for platforms that don't allow unaligned memory access.
- 1.40.6
* team: also set empty port configuration so teamd
knows about the port.
* team: restore port configuration after teamd respawn.
- 1.40.4
* dhcp: revert restarting DHCP when MAC address changes,
for example during a bond fail over.
* various documentation fixes.
* fix non-exported ABI in libnm which was wrongly present
in the header files but unusable so far.
* ifcfg-rh: fix writing ethtool pause settings to file.
* core: set "proto static" for manual routing rules configured
by NetworkManager.
* Various minor bugfixes.
- 1.40.2
* Ensure that resolv.conf gets updated when the configuration changes.
* Fix setting as bond primary an interface that doesn't exist yet when the
bond is activated.
* The number of autoconnect retries is now accounted independently for each
device when there are profiles with multi-connect=multiple.
* Don't print duplicate entries in the output of "NetworkManager
--print-config"
* Fix the ifcfg-rh plugin to properly read infiniband P-Key connection
profiles without an explicit interface name.
* Allow the removal of a bond port connection profile from the bond via
nmcli.
* Fix race condition during the activation of veth profiles when the peer
already exists.
* Decline the DHCPv6 lease if all addresses fail IPv6 duplicate address
detection (DAD).
* Wait that devices get carrier before trying to resolve the system hostname
on them via DNS.
* Fix race condition during the initial activation of OVS interfaces.
* Profiles generated by nm-initrd-generator now have lower than default
priority.
* Fix error when adding many SR-IOV virtual functions (VFs).
=============================================
NetworkManager-1.40
Overview of changes since NetworkManager-1.38
=============================================
* Drop unused, internal systemd DHCPv4 client. This is long
replaced by nettools' n-dhcp4 implementation.
* The nmcli command now supports --offline argument with "add" and
"modify" commands, allowing operation on keyfile-formatted connection
profiles without the service running (e.g. during system provisioning).
* The device state file /run/NetworkManager/devices/$ifindex now has
new sections [dhcp4] and [dhcp6] containing the DHCP options for the
current lease.
* Add multipath TCP (MPTCP) support. NetworkManager can now configure IP addresses
as MPTCP endpoints. This is configurable via the "connection.mptcp-flags"
property. The default setting is such that MPTCP handling is automatically
enabled if the kernel sysctl "/proc/sys/net/mptcp/enabled" indicates so.
NetworkManager does not enable the MPTCP sysctl or adjust the limits (ip mptcp limits).
The administrator or the distribution is supposed to configure the desired system
settings.
Note that strict reverse path filtering (rp_filter) breaks many MPTCP use cases.
With MPTCP handling enabled, NetworkManager will relax a strict (1) rp_filter
to loose (2). Otherwise rp_filter is untouched by NetworkManager.
* NetworkManager expanded log messages for invalid DHCP options.
* Fix the requirement of hardware address for DHCPv6, by dropping it.
* Increase the PMK lifetime for Wi-Fi connections using WPA-EAP.
* "nmcli networking off" now waits for deactivations to complete.
* Improve the appearance of nm-settings-nmcli man page by preserving
paragraphs.
* Support enabling ipv4ll alongside DHCPv4 and static addressing.
* Support configuring "ipv6.mtu".
* The "ipv6.addr-gen-mode" property can now have a default value
specified via global connections defaults in NetworkManager.conf.
* Honor "nm.debug" kernel command line to enable debug logging of
NetworkManager.
* NetworkManager reads the kernel command line "/proc/cmdline" for several
purposes, including "nm.debug" for enabling debugging and the
"match.kernel-command-line" setting in the profile. NetworkManager now
first looks now for "/run/NetworkManager/proc-cmdline", which allows to
overwrite the command line.
* Improve the reapply of non-bridge properties.
* Honor adding a Bluetooth NAP connection with all available methods.
* Improve carrier detection.
* During the build, stop relying on intltool for i18n and use gettext only.
* Undeprecate nm_remote_connection_get_secrets() in libnm.
* NetworkManager now will restart DHCP if the MAC changes on a device.
* Several internal improvements.
The following changes were backported to 1.38.x releases between 1.38.0
and 1.38.4 are also present in NetworkManager-1.40:
- 1.38.4
* Fix DAD for DHCPv6 addresses.
* Wi-Fi: improvements for OWE networks.
* Support EC private keys.
* Fix nmcli tab completion support for embedded quote characters.
* Fix reapply for lldp/mdns/llmnr/dns-over-tls settings.
* Various bugfixes.
- 1.38.2
* Fix race condition with pppd that caused failures when activating
PPPoE connections.
* Unbreak DHCPv6 over PPP.
* Don't ignore IPv6 DNS servers received from PPP.
* Fix crash while checking WEP capability of Wi-Fi interfaces.
* Ensure DHCP is restarted every time the link goes up.
* Fix struct alignment issues seen on some architectures.
* Various other bugfixes and improvements.
=============================================
NetworkManager-1.38
Overview of changes since NetworkManager-1.36
=============================================
* Add support for route type "throw".
* Fix bug setting priority for IP addresses.
* Static IPv6 addresses from "ipv6.addresses" are now preferred over
addresses from DHCPv6, which are preferred over addresses from autoconf.
This affects IPv6 source address selection, if the rules from
RFC 6724, section 5 don't give a exhaustive match.
* Static IPv6 addresses from "ipv6.addresses" are now interpreted with
first address being preferred. Their order got inverted. This is now
consistent with IPv4.
* Wi-Fi hotspots will use a (stable) random channel number unless one is
chosen manually.
* Don't use unsupported SAE/WPA3 mode for AP mode.
* NetworkManager will no longer advertise frequencies as supported when
they're disallowed in configured regulatory domain.
* Attempt to connect to WEP-encrypted Wi-Fi network will now fail
gracefully with a recent version of wpa_supplicant when built
without WEP support. As long as wpa_supplicant supports WEP,
NetworkManager will continue to work.
* Disable WPA3 transition mode for wifi.key-mgmt=wpa-psk if the NIC
does not support PMF. This is known to cause problems in some setups. It
is still possible to explicitly configure wifi.key-mgmt=sae for WPA3.
* Add new dummy crypto backend "null" that does nothing. NetworkManager
uses the crypto library when handling certificates for 802.1x profiles.
* Veth devices with name "eth*" are now managed by default via the
udev rule. This is to support managing the network in LXD containers.
* The hostname received from DHCP is now shortened to the first dot
(or to 64 characters, whatever comes first) if it's too long.
* As the insecure WEP encryption for Wi-Fi network is phased out,
nmcli now discourages its use when activating or modifying a
profile.
* Fix connectivity checks in case the check endpoint address resolves to
multiple addresses.
* Workaround libcurl blocking NetworkManager while resolving DNS names.
* nmcli: indicate missing Wi-Fi hardware when showing rfkill setting.
* nmcli: add connection migrate command to move a profile to a specified
settings plugin. This allows to convert profiles in the deprecated ifcfg-rh
format to keyfile.
* Set "src" attribute for routes from DHCPv4 to the leased address. This
helps with source address selection.
* Updated translations.
* Various bugfixes and internal improvements.
The following changes were backported to 1.36.x releases between 1.36.0
and 1.36.4 are also present in NetworkManager-1.38:
- 1.36.4
* The internal DHCPv4 client now discards NAKs packets coming
from servers different from the one that sent the offer.
* Fixed a couple of regressions in PPPoE support since 1.36.0.
* Fix potential libnm crash when the client object initialization gets
canceled.
* Other various fixes and improvements.
- 1.36.2
* When the list of plugins is not specified via "main.plugins" in
NetworkManager.conf and no build-time default is set with
"--with-config-plugins-default" configure argument, now all known
plugins found in the plugin directory are loaded (and the built-in
"keyfile" plugin is preferred over others).
* Preserve external ports during checkpoint rollback
* Fix removal of ovsdb entry when an OVS interface goes away
* Fix DNS configuration for WWAN connections
=============================================
NetworkManager-1.36
Overview of changes since NetworkManager-1.34
=============================================
* The handling of Layer 3 configurations has been substantially reworked.
While this is mostly internal change, it results in more robust
behavior when addressing information from multiple sources (DHCP,
manually configured, VPN) need to be applied simultaneously.
Overall performance and memory use have also slightly improved.
* Manually configured addresses can no longer expire even if the same
addresses are also obtained dynamically.
* Code for systemd-based DHCP and DHCPv6 clients has been updated from
upstream.
* NTP servers obtained via DHCPv6 are now exposed on the DBus API, visible
in nmcli and available for use by dispatcher scripts.
* 5G NR (New Radio) modems are now supported.
* The "rd.znet_ifnames" kernel command line option is now honored on
network bootups on an IBM s390 platform.
* Wi-Fi P2P support does now work with the IWD backend, in addition to
wpa_supplicant backend.
* Support for special route types have been added: "prohibit", "blackhole"
and "unreachable".
* Routes managed by routing daemons are now ignored. This is done to
address a performance bottleneck on specialized routers.
* Handling of IP addressing and routing information is now slightly
more efficient and uses less memory. This is apparent on systems with
large amount of IP configuration information.
* It is now possible to start NetworkManager without root user privileges.
This is experimental doesn't necessarily result in a working daemon.
NetworkManager service already drops many of capabilities available
to the root user.
* WPA3 Wi-FI network security have been improved by enabling new H2E (hash
to element) method for generating SAE password element.
* It is now possible to select the default Wi-Fi backend (wpa_supplicant or
IWD) at build-time.
* Replies from broken DHCP servers that send duplicate address or mask
options are now handled gracefully.
* Bridge support has gained the possibility of turning off MAC ageing.
* "configure-and-quit" mode and nm-iface-helper have been removed.
* A number of bugs that could cause NetworkManager to crash in rare
conditions have been fixed.
=============================================
NetworkManager-1.34
Overview of changes since NetworkManager-1.32
=============================================
* initrd: wait for both IPv4 and IPv6 with "ip=dhcp,dhcp6".
* core: better handle sd-resolved errors when resolving hostnames.
* nmcli: fix import WireGuard profile with DNS domain and address
family disabled.
* ndisc: send router solicitations before expiry.
* policy: send earlier the ip configs to the DNS manager.
* core: support linking with LLD 13.
* wireguard: importing wg-quick configuration files with nmcli
no longer sets a negative, exclusive "dns-priority". This plays
better with common split DNS setups that use systemd-resolved.
Adjust the "dns-priority" to your liking after import yourself.
* NetworkManager no longer listens for netlink events for traffic
control objects (qdiscs and filters).
* core: add internal nm-priv-helper service for separating privileges
and have a way to drop capabilities from NetworkManager daemon.
* bond: add support for setting queue-id of bond port.
* dns: support configuring DNS over TLS (DoT) with systemd-resolved.
* nmtui: add support for WireGuard profiles.
* nmcli: add aliases `nmcli device up|down` beside connect|disconnect.
* conscious language: Deprecate 'Device.Slaves' D-Bus property in favor of new
'Device.Ports' property. Depracate 'nm_device_*_get_slaves()' in favor of
'nm_device_get_ports()' in libnm.
* nmcli: invoking nmcli command without arguments will now show 'default'
instead of null address in route4 or route6 section.
The following changes were backported to 1.32.x releases between 1.32.0
and 1.32.12 are also present in NetworkManager-1.34:
- 1.32.12:
* Fix wrong order of addresses when restarting NetworkManager.
* Preserve the IPv6 ff00::/8 route added by kernel in the local table,
necessary for multicast communication.
* Fix emitting the signal for changed metered status of devices.
* Fix applying the ethtool autonegotiation and speed settings.
* initrd: fix crash parsing plain '=' without key.
* cloud-setup: use suppress_prefixlength rule to honor
non-default-routes in the main table.
- 1.32.10:
* core: fix the order of IPv6 addresses changing on service restart.
* initrd: add command line option to configure link autonegotiation
and speed.
* ifcfg-rh: fix crash when parsing invalid DNS address.
* ifcfg-rh: extend ifup/ifdown scripts to work with connection profile
names.
* udev: also react to "move" (and "change") udev actions in our rules.
- 1.32.8:
* firewalld: configure zones on "Reloaded" signal.
* core: fix wrong MTU for bridge interfaces.
* cloud-setup: fix gateway address for Aliyun cloud.
- 1.32.6:
* core: fix adding stale local routes when address changes.
* initrd: tag generated profiles with origin in user data.
* core: introduce "allowed-connections" option to disallow
profiles on a device. This allows to filter out profiles
that originate from initrd.
* core: introduce "keep-configuration" device option to forcefully
activate a profile on start.
* dhcp: handle filename/bootfile_name DHCP option and write it to
device state file for initrd/kickstart.
* initrd: add "ib.pkey=" command line option
- 1.32.4:
* core: remove stale entries from "seen-bssids" and "timestamp"
files in "/var/lib/NetworkManager".
* bond: support the peer_notif_delay option.
* core: add ipv[46].required-timeout option to wait for IP
configuration while activating.
* core: send ARP announcements when there is carrier.
* core: start DHCPv6 when a prefix delegation is needed for shared
mode.
* firewall: fix nftables backend to create "ip" table for
IPv4 only.
* initrd: set required-timeout of 20 seconds for default IPv4 configuration
to opportunistically wait for IPv4.
* ifcfg: log warning about invalid keys in ifcfg files.
* ifcfg: reject non-UTF-8 from ifcfg files.
* nmcli: show DNS SEARCH field in device information.
* cloud-setup: add support for Aliyun cloud.
- 1.32.2:
* hostname: prefer IPv4 addresses for reverse DNS lookup.
* dhcp: ignore unauthenticated FORCERENEW messages with
internal, systemd-based DHCPv4 plugin (CVE-2020-13529).
This plugin is not used, unless the undocumented dhcp=systemd
option was set.
* cloud-setup: preserve IP addresses, routes and rules from
currently active connection profile.
* Various bugfixes and performance improvements.
=============================================
NetworkManager-1.32
Overview of changes since NetworkManager-1.30
=============================================
* Add an 'accept-all-mac-addresses' property to the ethernet setting
to accept frames with any MAC address (also known as promiscuous
mode).
* nmcli: fix setting property aliases to empty value to reset the
default value.
* BEHAVIOR CHANGE: Enforce valid lower case UUID format for the "connection.uuid"
by normalizing the value. This changes the UUID of existing profiles with an
invalid or non-normalized value. Also normalize "connection.secondaries" to only
contain valid and distinct UUIDs. Profiles that set "connection.master" or the
"parent" properties to a non-normalized UUID need adjustment. Using such
non-normalized UUIDs should be rare and affect few users.
* API CHANGE: D-Bus: remove long deprecated "PropertiesChanged" signal from D-Bus
API. They are replaced by standard "PropertiesChanged" signal on the
"org.freedesktop.DBus.Properties" interface. It is not expected that anybody
is still using this API.
* Now NetworkManager uses systemd-resolved API to lookup the system
hostname via reverse DNS. If systemd-resolved is not available, a
'nm-daemon-helper' binary is spawned to perform the lookup using
the 'dns' NSS module.
* dhcp: honor "ID_NET_DHCP_BROADCAST" udev attribute to set the broadcast flag.
This allows to configure devices in udev for which DHCPOFFER messages are to be
broadcast.
* firewall: add nftables firewall backend for configuring IPv4 NAT with shared
mode. Now two backends are supported, "iptables" and "nftables". The default
gets detected based on whether /usr/sbin/nft or /usr/sbin/iptables is installed,
with nftables preferred.
Please note that SELinux might prevent NetworkManager from communicating with nft.
* ethtool: add support for pause settings.
* Support "prohibit"/"blackhole"/"unreachable" type routing rules.
* Support uidrange attribute for policy routing rules.
* Now NetworkManager preserves by default the existing traffic control
configuration (qdiscs and filters) when activating a connection.
* wifi/iwd: mirror NetworkManager connection profiles to iwd config files.
* API CHANGE: vala: fix wrongly generated vapi for WireGuard API.
* wifi: fix parsing of Microsoft Network Cost information element for
detecting metered networks.
* dhcp: support option 249 (Microsoft Classless Static Route) with nettools
internal DHCP plugin.
* initrd: support the "rd.net.dhcp.retry" kernel argument for controlling retry
and timeout to get a DHCP lease.
* API CHANGE: hide definitions of structs for NMSetting and NMSimpleConnection from
public headers.
* Major restructuring of the source code.
* Many bugfixes and minor improvements.
=============================================
NetworkManager-1.30
Overview of changes since NetworkManager-1.28
=============================================
* Increase timeout of NetworkManager-wait-online.service to 60 seconds.
* Add "ipv4.dhcp-client-id=ipv6-duid" option for RFC4361.
* The dhcpcd plugin now requires a minimum version of dhcpcd-9.3.3 with
the --noconfigure option. Using an older version will cause dhcpcd to
exit with a status code of 1.
* Support building against musl libc.
* Support new ethtool offload features.
* Add support for WPA3 Enterprise Suite-B 192 bit mode.
* Add support for handling Veth devices.
* New hostname settings for controlling configuring the hostname from
reverse DNS lookup and from DHCP.
* OVS: support configuring external-ids.
* libnm: nm_setting_bond_add_option() no longer validates the
option that is set. Instead, use nm_connection_verify() to validate
the profile.
* libnm: add support for reading/writing keyfile format. This required to
relicense previously GPL-2.0+ code as LGPL-2.1+ with the agreement of the
copyright holders.
* initrd: support for rd.net.timeout.carrier option.
* initrd: support new ip method "link6" for IPv6 link-local only.
* ci: use ci-templates for containers on gitlab-ci.
* ci: test build against Alpine Linux on gitlab-ci.
* build: new configure option to set path to "polkit-agent-helper-1".
* Many bugfixes, improvements and translation updates.
=============================================
NetworkManager-1.28
Overview of changes since NetworkManager-1.26
=============================================
* Introduce a new "rc-manager=auto" setting and make it the default,
unless a different default is chosen at compile time. This mode
tries to detect "systemd-resolved", "resolvconf", and "netconfig"
and chooses the mode that seems most suitable depending on build
setting and runtime detection. "resolvconf" and "netconfig" are
only considered iff NetworkManager was built with the respective
options enabled.
* The long deprecated D-Bus property "Ip4Address" on
"org.freedesktop.NetworkManager.Device" interface is now defunct and
always returns zero.
* Introduce a ipv4.dhcp-reject-servers connection property that
specifies a list of DHCP server-ids from which offers should be
rejected.
* Add a ipv4.dhcp-vendor-class-identifier connection property to send
a custom value for the Vendor Class Identifier DHCP option.
* Support obtaining the system hostname through the FQDN DHCPv6
option.
* dbus: don't require policykit permission for GetAppliedConnection of
a device.
* When supported by kernel, use netlink to configure bridge settings
instead of writing to sysfs.
* Deprecate the "active_slave" bond option which now has the same effect
as setting the "primary" option.
* The initrd generator now also accepts MAC addresses to indicate
interfaces.
* Add a new provider for nm-cloud-setup to support automatic network
configuration on Azure.
* The initrd generator now supports creating Infiniband connections.
* Fix running DHCPv6-PD over PPPoE.
* Fix building NetworkManager with LTO (Link Time Optimization).
* Fix failure activating Wi-Fi P2P connections.
* Reformat code using spaces instead of tabs. Also, the entire C
source code is now formatted with "clang-format" (version 11.0).
* Change the behavior of nm-initrd-generator so that the 'ip=off|none' kernel
cmdline argument actually generates a connection which disables both
ipv4 and ipv6. Previously the generated connection would disable ipv4
but ipv6 would be set to the 'auto' method.
* Fix systemd-resolved DNS plugin to configure DefaultRoute option and to
only configure wildcard DNS search domain with exclusive DNS priority.
=============================================
NetworkManager-1.26
Overview of changes since NetworkManager-1.24
=============================================
* Add a new build option 'firewalld-zone'; when enabled,
NetworkManager installs a firewalld zone for connection sharing and
puts interfaces using IPv4 or IPv6 shared mode in this zone during
activation. The option is enabled by default.
Note that NetworkManager still calls to iptables to enable
masquerading and open needed ports for DHCP and DNS. The new option
is useful on systems using firewalld with the nftables backend,
where the iptables rules would not be sufficient.
* Extend the syntax for 'match' setting properties with '|', '&', '!'
and '\\'.
* Add MUD URL property for connection profiles (RFC 8520) and set it
for DHCP and DHCPv6 requests.
* Expose raw LLDP message on D-Bus and the MUD usage description URL.
* ifcfg-rh: handle "802-1x.{,phase2-}ca-path". Otherwise setting this
property silently fails and a profile might accidentally not perform
any authentication (CVE-2020-10754).
* ifcfg-rh: handle 802-1x.pin properties.
* ethernet: reset original autonegotiation/speed/duplex settings when
deactivating device.
* Support ethtool coalesce and ring options.
* Allow team connections to work without D-Bus (e.g. in the initrd).
* Wi-Fi profiles now also autoconnect if all previous activation attempts
failed. This means, an initial failure to autoconnect to the network will
no longer block the automatism. A side effect is that existing Wi-Fi profiles
which previously were blocked may now start to autoconnect.
* NetworkManager now supports "local" type routes beside "unicast".
* Introduce new manual pages nm-settings-dbus and nm-settings-nmcli.
* Mark externally managed devices and profiles on D-Bus.
* Highlight externally managed devices in nmcli.
* Add support for a number of bridge options.
* Add match for device path, driver and kernel command line for connection
profiles.
* Fix support for OVS patch interfaces.
* Support more tc qdiscs: tbf and sfq.
* Add new provider in nm-cloud-setup for Google Cloud Platform which
automatically detects and configures the host to receive traffic
from internal load balancers.
=============================================
NetworkManager-1.24
Overview of changes since NetworkManager-1.22
=============================================
* Add support for virtual routing and forwarding (VRF) interfaces.
* Add support for Opportunistic Wireless Encryption mode (OWE) for Wi-Fi networks.
* Add support for 31-bit prefixes on IPv4 point-to-point links according to
RFC 3021.
* Drop dependencies for libpolkit-agent-1 and libpolkit-gobject-1.
* nmcli:
- support setting removal via new command
`nmcli connection modify $CON_NAME remove $setting`.
- support backslash escape sequences for "vpn.data", "vpn.secrets",
"bond.options", and "ethernet.s390-options".
* bridge: support new options "bridge.multicast-querier", "bridge.multicast-query-use-ifaddr",
"bridge.multicast-router", "bridge.vlan-stats-enabled", "bridge.vlan-protocol",
"bridge.group-address".
* IPv6 SLAAC: add support for "ipv6.ra-timeout" setting
* IPv6 DHCP: add support for "ipv6.dhcp-timeout" setting
* WWAN: NetworkManager now detects if a PIN-protected SIM card has been
externally unlocked and automatically tries to activate a suitable
connection on the modem.
* OVS:
- add support for changing MTU of OVS interfaces.
- remove length limitation for OVS Bridge, Patches and Interfaces
(only Patch types) names.
* VPN: accept empty values for VPN data items and secrets.
* All nm-devices now expose the 'HwAddress' property via D-Bus.
* Slave devices now do not get created/activated if master is missing.
* Fixed multiple issues in the internal "nettools" DHCP client.
* Export NM_CAPABILITY_OVS capability on D-Bus and in libnm to
indicate that the OVS plugin is loaded.
* Fixes for importing WireGuard profiles in nmcli and better handle
configurations that enable ip4-auto-default-route with an explicit
gateway.
* Various bug fixes and improvements.

NetworkManager-1.22
Overview of changes since NetworkManager-1.20
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* Drop support for BlueZ 4. BlueZ 5 was released in 2012 and should
nowadays be available everywhere.
* DHCP: switch "internal" DHCPv4 plugin from code based on systemd to use nettools'
n-dhcp4 library.
* Add support for "scope" attribute for IPv4 routes.
* Add support for specifying IAID and FQDN flags for DHCP request.
* Add a '802-1x.optional' property to consider the wired 802.1X authentication as
optional.
* Use the Network Cost Wi-Fi information element to determine metered
device state.
* Support main.auth-polkit=root-only setting to disable PolicyKit use and
restrict authorization to root user.
* core: declare "startup complete" when device reaches "connected"
state, even if IP addressing methods did not yet fully complete.
This changes behavior for unblocking "NetworkManager-wait-online.service",
and "network-online.target" earlier. If this causes issues in your
setup, you may need to configure "ipv4.may-fail=no" or "ipv6.may-fail=no",
which delays reaching "connected" state for the address family accordingly.
* libnm: hide NMObject and NMClient typedefs from header files. This prevents
the user from subclassing these types and is an ABI change (in the unlikely
case that a user was subclassing the types, which is no longer supported).
* libnm: retire deprecated WiMAX API NMDeviceWimax and NMWimaxNsp.
WiMAX support was removed from NetworkManager in version 1.2 (2016) and no such
type instances would have been created by NMClient for a while now.
* Deprecate synchronous API for D-Bus calls in libnm. We don't remove libnm API so
you are free to continue using it. But tells you that using it might be a bad idea.
* libnm: heavily internal rework NMClient. This slims down libnm and makes the
implementation more efficient. NMClient should work now well with a separate
GMainContext.
* Add `nmcli general reload` subcommand to reload NetworkManager configuration
and DNS settings.
* nm-cloud-setup: add new tool for automatically configuring NetworkManager
in cloud. This is still experimental and currently only EC2 and IPv4 is
supported.
* Add new NetworkManager logo to "contrib/art/logo".
* Various bug fixes and improvements.
=============================================
NetworkManager-1.20
Overview of changes since NetworkManager-1.18
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* The libnm-glib library, deprecated in favor of libnm since NetworkManager 1.0,
and disabled by default since NetworkManager 1.12, has now been removed.
* The DHCP client now defaults to "internal". The default can be overridden
at build time by using the --with-config-dhcp-default option of the
configure script or at run time by setting the main.dhcp option in the
configuration file.
* Added support for configuring fq_codel line discipline and mirred action.
* Added a possibility for distributions to ship dispatcher scripts in /usr/lib.
* Drop deprecated setting "main.monitor-connection-files" in NetworkManager.conf.
This setting now has no more effect and was disabled by default for a long time.
Instead, after changes, load files explicitly with `nmcli connection load` or
`nmcli connection reload`.
* Rework parsing team JSON config in libnm and stricter validate settings.
With this, NetworkManager rejects settings that it considers invalid while
still allowing setting arbitrary JSON config directly.
* Drop ibft settings plugin. This functionality is now covered by using
nm-initrd-generator from initrd to pre-generate in-memory profiles.
* Support "suppress_prefixlength" attribute for policy routing rules.
This is what wg-quick uses for the "Improved Rule-based Routing" solution,
and the user can now manually configure such policy routing rules.
* Support "wireguard.ip4-auto-default-route" and "wireguard.ip6-auto-default-route".
This automatically implements the "Improved Rule-based Routing" of wg-quick
to help avoiding routing loops when setting the default-route on the WireGuard
interface. Note that this is now enabled by default, so there is a change in behavior
if your WireGuard connection profiles from before had a default-route (/0)
in allowed-ips.
* Rework implementation of settings plugins and how profiles are presisted
to disk. This is a large internal refactoring of the settings plugins that
allows to migrate a connection profile between plugins.
* In-memory profiles are now only handled by keyfile plugin and will also be
persisted to /run directory. This allows to restart NetworkManager without
loosing these profiles and it provides a file-system based API for creating
in-memory profiles.
* Keyfile plugin now supports a read-only directory of profiles under directory
"/usr/lib/NetworkManager/system-connections". Such profiles still can be modified
and deleted via D-Bus, which results in writing profiles to /etc or /run that
shadow the read-only files.
* Add new D-Bus method AddConnection2() that allows to block autoconnect of
the profile at the moment when creating the profile. Also add support for
this API to libnm.
* Add flag "no-reapply" to Update2() D-Bus method. Normally, when a connection
profile gets modified, this only changes the profile itself. When the profile
is currently activated on a device, then the device's configuration does not update
before the profile is fully re-activated or Reapply on the device is called. There
is an exception to this: the "connection.zone" and the "connection.metered"
properties take effect immediately. The "no-reapply" flag allows suppressing to
reapply any properties, so that no changes take effect automatically. The purpose
is to really only modify the profile itself without changes to the runtime configuration
of the device.
* Add "ipv6.method=disabled" to disable IPv6 on a device, like also possible for
IPv4. Until now, the users could only set "ipv6.method=ignore" which means the
users are free to set IPv6 related sysctl values themselves.
* Added support for Wi-Fi Mesh network.
The following changes were backported to 1.18.x releases between 1.18.0
and 1.18.2 are also present in NetworkManager-1.18:
- 1.18.2:
* Add compatibility with out-of-tree WireGuard module on 5.2 kernels
* Fix parsing of BOOTIF= variables in initrd.
* Accept numeric IPv4 prefix in place of a mask when parsing a command line
in initrd.
* Don't check connectivity of unconfigured devices.
* Fix PKCS#12 handling in the ifcfg-rh plugin.
* Avoid waiting for udev to see software devices created by NetworkManager.
* Don't attempt to stop management daemon for Team devices created
externally to NetworkManager.
* Use FQDN for persistent hostname on Slackware.
* Restore IPv6 configuration of a device when its link goes back up.
* Fix management status of software devices on system suspend.
* Make nmcli not print certificate blobs if --show-secrets is not used.
* Fix MTU reapply.
=============================================
NetworkManager-1.18
Overview of changes since NetworkManager-1.16
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* Add support for policy routing rules.
* Add support for VLAN filtering for Linux bridge.
* Support ieee-802-1 and ieee-802-3 LLDP TLVs.
* Allow large MTU sizes for infiniband/IPoIB connection profiles.
* Improve nmcli's handling of list options for connection properties.
=============================================
NetworkManager-1.16
Overview of changes since NetworkManager-1.14
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* Check connectivity per address family.
* Support "main.systemd-resolved" to let NetworkManager configure DNS settings
in systemd-resolved without making it the main DNS plugin of NetworkManager.
* Write "/var/run/NetworkManager/no-stub-resolv.conf" with original nameservers.
That is useful with caching DNS plugins like "systemd-resolved" or "dnsmasq" where
"/var/run/NetworkManager/resolv.conf" refers to localhost.
* Change default "ipv4.dhcp-client-id" setting for the internal DHCP plugin from
"duid" to "mac". This is a change in behavior on upgrade when using the internal
DHCP plugin (unless the default is overwritten in "NetworkManager.conf" or specified
per connection profile).
* Improve handling of DHCP router options with internal DHCP plugin. For one, accept
multiple routers and add a default-route to each. On D-Bus expose the original DNS
and NTP servers without cleaning up local nameservers.
* Allow binding a connections lifetime to the DBus client that activated it.
* Add support for establishing Wi-Fi Direct connections (Wi-Fi P2P).
* Add support for WireGuard VPN tunnels to NetworkManager. D-Bus API and libnm
support all options. nmcli supports creating and managing WireGuard profiles,
with the exception of configuring and showing peers.
* Add initrd generator to be used by dracut and use it as new way of handling
iBFT.
* Deprecated "plugins.monitor-connection-files" setting in NetworkManager.conf.
This option will have no effect in future versions.
* Add AP and Ad-hoc support for iwd Wi-Fi backend.
* Warn about invalid settings in "NetworkManager.conf".
* Support announcing "ANDROID_METERED" DHCP option for shared mode.
* Support SAE authentication as used for 802.11s Meshing and WPA3-Personal.
* NetworkManager is no longer installed as D-Bus activatable service.
* Mark docker bridges as unmanaged via udev rule.
* Add new PolicyKit permission "org.freedesktop.NetworkManager.wifi.scan" for controlling
Wi-Fi scanning.
The following changes were backported to 1.14.x releases between 1.14.0
and 1.14.6 are also present in NetworkManager-1.14:
- 1.14.6:
* Fix memory corruption in internal DHCPv6 client (CVE-2018-15688).
* No longer limit number of search entries in resolv.conf to 6.
* Support restricting NetworkManager.conf device configuration based on used DHCP
plugin.
* Add "${MAC}" specifier for connection.stable-id. This uses the current MAC
address for seeding the stable generation of MAC address, DHCP client-id
or IPv6 stable-privacy interface identifier.
* Support special value "duid" for "ipv4.dhcp-client-id". This generates an
RFC4361-compliant client-id like the internal DHCP client used to do by default.
Previously, there was no explicit name for such a client-id and it was not
usable with dhclient DHCP plugin. This also generates the same client-id as
systemd-networkd does by default.
* Support and use a new kind of secret-key in "/var/lib/NetworkManager/secret_key".
The secret-key represents the identity of the machine that is used for various
purposes like generating IPv6 stable privacy addresses. It is now combined
with "/etc/machine-id" so that changing only the machine-id results in new identifiers.
That matters for example when cloning a virtual machine. Previously, the user
