===============================================
NetworkManager-1.42.4
Overview of changes since NetworkManager-1.42.2
===============================================
* Fix a possible crash when [global-dns] is used and improve the
documentation.
* Documentation improvements.
===============================================
NetworkManager-1.42.2
Overview of changes since NetworkManager-1.42.0
===============================================
* Add build option to set the mobile-broadband-provider-info database
path.
* Add new "ipv[46].replace-local-rule" setting to control whether to
remove the local route rule that is automatically generated.
* Add the DHCPv6 IAID to the lease information exposed in /run and on
D-Bus.
* Fix assuming team connections at boot.
* Fix race condition when setting the MAC address of an OVS interface.
* Fix constructing the IPv4 name servers variable passed to dispatcher
scripts.
* Don't use tentative IPv6 address to resolve the system hostname via DNS.
* Deprecate the "Master" property of the NMActiveConnection D-Bus object
in favor of the new "Controller" 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".
* 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.

* 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 overriden
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
hard to prune NetworkManager's secret-key to get a new identity, now regenerating
machine-id suffices. Secret-keys generated by earlier versions of NetworkManager are
not affected and keep their previous behavior.
* Fix the DHCP client-ids based on the MAC address of IPoIB/infiniband devices.
* Fix restoring IP configuration after interface went down.
* No longer let NetworkManager touch rp_filter setting. The rp_filter sysctl must now
be set outside of NetworkManager according to the admin's preference. Note that a strict
rp_filter may break valid use-cases and interacts badly with connectivity checking.
* Various bug fixes and improvements.
- 1.14.4:
* Fix a crash in nmcli when a device is removed while being disconnected.
* Fix a crash in ifupdown (Debian) configuration plugin.
* Fix a daemon crash when a generated connection doesn't validate.
* Fix a memory leak in dhclient DHCP plugin.
* Fix line editing in nmcli password prompts.
* Fix a RPATH in bluetooth and wwan plugin when built with Meson (otherwise
they wouldn't find libnm-wwan.so).
- 1.14.2:
* Fix a bug that could cause NetworkManager to crash after checking
connectivity status.
* Correctly apply a default (-1) metric from DHCP.
* Multiple fixes for IWD Wi-Fi backend.
* Multiple fixes for builds with Meson build system.
* Fix a crash with OLPC XO-1 mesh Wi-Fi.
* Fix handling "serial.parity" and "serial.send-delay" properties in nmcli.
* Improve auto-selecting device when activating a connection profile
and don't auto-select unmanaged devices when activating multi-connect
profile.
* Avoid expiring the lifetime of IPv6 addresses from router advertisements.

NetworkManager-1.14
Overview of changes since NetworkManager-1.12
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* Added support for IEEE 802.15.4 and 6LowPAN devices.
* Support activating profile multiple times via connection.multi-connect
setting.
* Add match setting to restrict a profile to devices based on
a list of interface names with globbing supported.
* Fix PrimaryConnection for VPN with default-route.
* Add support for ethtool offload features.

* Deprecate endian-dependent D-Bus API and add new API that can be
used instead (rh#1153559).
* Add support for ip6gre/ip6gretap IP tunnels.
* Add support for detecting WireGuard interfaces (WireGuard VPN cannot
be controlled via NetworkManager).
* Add support for configuring SR-IOV devices.
* Improve error reporting of activation when no device is available.
* Support reapplying changes of the route metric.
* Support EAP profiles with iwd Wi-Fi backend and support iwd API 0.8.
* Expose slaves of OVS bridges and ports.
The following changes were backported to 1.12.x releases between 1.12.0
and 1.12.2 are also present in NetworkManager-1.14:
* fix missing symbols in libnm ABI for settings.
=============================================
NetworkManager-1.12
Overview of changes since NetworkManager-1.10
=============================================
This is a new stable release of NetworkManager. Notable changes include:
* Improved support for configuration checkpoint, including support in libnm.
* Added capability to set IP Tunnel configuration flags.
* The systemd-resolved DNS plugins now supports MDNS.
* systemd-resolved and dnsmasq DNS plugins now honor the DNS priority setting.
* Wi-Fi devices now support FILS for speedier roaming support.
* Drop dependency on libnl3 library.
* Add support for "onlink" routes.
* More robust connectivity checking.
* Dropped the obsolete "ifnet" settings plugin,
* Try harder to generate reasonable human-readable names for devices even if
the hwdb contains garbage.
* Add an "overview" option to hide default values in nmcli, resulting in more
concise output.
* Reworked the inner workings of D-Bus interface for better resource efficiency.
* Add support for configuring nmcli coloring via terminal-colors.d(5).
* Added experimental support for Meson build system,
* Added initial IWD Wi-Fi daemon support.
* A non-hexadecimal DHCPv4 client-id is now properly passed to
dhclient with the first byte (type) set to zero, as stated in the
documentation. This represents a change in behavior since previous
versions where the first character of the string was used as
type. The internal client is not affected by the change.
* DNS setting rc-manager=file now always follows dangling symlinks
instead of replacing /etc/resolv.conf with a plain file.
* Added wake_on_wlan connection setting to configure
wake-on-wireless-lan (WoWLAN).
* The libnm-glib library, deprecated in favor of libnm since NetworkManager 1.0,
is now not built by default. While it can still be enabled, the distributions
should have a good plan for removing it if they need to keep shipping it at
this point.
* nmcli now scans for Wi-Fi networks before displaying them, if the last scan
was too long ago.
* Added the ipv6.dhcp-duid property to allow configuring the DHCPv6 DUID
* Extended ipv6.dhcp-client-id property to support DHCP client identifiers
depending on the MAC address and the stable ID.
* Set NM_DISPATCHER_ACTION environment variable in dispatcher scripts.
The following features were backported to 1.10.x releases from 1.10.0 to
1.10.10 are also present in NetworkManager-1.12:
