Commit bb850fda0e ('nmcli: connection: process port-type, type
and controller first') started correctly rejecting IP configuration
on port connections.
However, previously nmcli would accept IP parameters for ports when
using a specific parameters order. To avoid breaking user scripts that
may have relied on this behavior, introduce a backward compatibility
quirk.
Specifically, nmcli accepts a disabled/ignore IP method on a port
connection. For any other IP setting on a port connection, a specific
error message is now shown.

(cherry picked from commit 165e5df6e0)
It is a little odd that client tests connect "UNAVAILABLE" devices, and
the devices return to "DISCONNECTED" after deactivation.
It differs from what happens in reality, and some client tools
(hey nm-cloud-setup) can break when they rightly assume that the
device is not ready for activation when it's "UNAVAILABLE" not
"DISCONNECTED".
Add support for configuring per-interface IPv4 sysctl forwarding setting
in NetworkManager. The feature allows users to configure the
net.ipv4.conf.<interface>.forward setting directly through
NetworkManager, enabling targeted forwarding configurations for
interfaces. This is particularly useful for cases such as enabling
forwarding for MetalLB load balancing without requiring a global
ip_forward=1 setting.
While forwarding setting can be managed via /etc/sysctl.conf,
configuring sysctl options for dynamically created or
software-configured interfaces (e.g., bridges) poses challenges. With
this feature, NetworkManager can configure these settings when
interfaces are created or updated, users no longer need to rely on
nm-dispatcher scripts for per-interface sysctl configuration, which can
be error-prone and complex. This feature ensures a more seamless and
integrated way to manage per-interface forwarding configurations,
reducing user overhead and improving usability in complex network
setups.
We do not support configuring per-device IPv6 sysctl forwarding because
in order to make per-device IPv6 sysctl forwarding work, we also need to
enable the IPv6 global sysctl forwarding setting, but this has potential
security concerns because it changes the behavior of the system to
function as a router, which expose the system to new risks and
unintended traffic flows, especially when enabling forwarding on the
interface the user previously explicitly disabled. Also enabling
per-device IPv6 sysctl setting will change the behavior of router
advertisement (accept_ra), which is not expected. Therefore, we
only support configuring per-device IPv4 sysctl forwarding option in
NetworkManager.

Always explicitly tear down pexpect instances and collect their
results. Assert on the results after orderly teardowns.
Track the current pexpect instance in test context so that it could be
still collected if the test blows up. That could provide more clue into
what went wrong in the test if it's due to a crash the testee.

It has presumably been moved out of TestNmcli at some point, but that
seems to have been in error, as it's also pretty specific to the nmcli
test cases. Not useful for cloud-init tests that also utilize
NMTestContext. Move it back.
We have encountered multiple incidents where users face connectivity
issues after booting, particularly due to hardware like switches that do
not pass traffic for a few seconds after startup. And services such as
NFS fail to mount because they try to initiate before the network is
fully reachable. Therefore, we are supporting
`connection.ip-ping-addresses` and `connection.ip-ping-timeout` to
allow administrators to configure the network to verify connectivity to
a specific target(such as a service like NFS) instead of relying on
gateway reachability, which may not always be relevant in certain
network configurations.

In nmcli we have renamed dhcp-send-hostname and dhcp-send-hostname-v2 to
dhcp-send-hostname-deprecated and dhcp-send-hostname so users don't need
to worry about the details of the weird workarounds that we sometimes
need to do to expand and/or deprecate some properties.
However, the autogenerated documentation didn't include this names. Add
---nmcli--- specific documentation, adding a new property-infos field
called "rename" with the new name used in nmcli. This field can be used
for more properties if we use the same strategy in the future.
The user does not want to send machine hostname to the DHCP server
globally by default to avoid ddns record getting created in IPAM.
otherwise, IPAM creates ddns records which might interfere with user's
regular host record. Thus, introduce the ternary property
dhcp_send_hostname_v2 to warrant this behavior.
Notice that we set the GSpec of dhcp-send-hostname-v2 to int, because
defining it as enum would make that it cannot be expanded in a backwards
compatible way if we need to add more values: old clients using libnm
would reject it due to the new value being unknown. Follow the same
strategy than _nm_setting_property_define_direct_enum, defining the
NMSettInfoPropertType as enum, but the glib's GSpec as int.

Add a new "ipv4.dhcp-ipv6-only-preferred" property to control the
"IPv6-Only Preferred" DHCPv4 option (RFC 8925). The option indicates
that a host supports an IPv6-only mode and is willing to forgo
obtaining an IPv4 address if the network provides IPv6 connectivity.
At the moment, the access point mode uses 20MHz channels. Introduce a
new 'wifi.channel-width' property that allows the use of a larger
bandwidth, thus increasing performances.
Commit 797f3cafee ('device: fall back to saved use_tempaddr value
instead of rereading /proc') changed the behaviour of how to get the
last resort default value for ip6-privacy property.
Previously we read it from /proc/sys/net/ipv6/conf/default, buf after
this commit we started to read /proc/sys/net/ipv6/conf/<iface> instead,
because the user might have set a different value specific for that device.
As NetworkManager changes that value on connection activation, we used
the value read at the time that NetworkManager was started.
Commit 6cb14ae6a6 ('device: introduce ipv6.temp-valid-lifetime and
ipv6.temp-preferred-lifetime properties') introduced 2 new IPv6 privacy
related properties relying on the same mechanism.
However, this new behaviour is problematic because it's not predictable
nor reliable:
- NetworkManager is normally started at boot time. That means that, if a
user wants to set a new value to /proc/sys/net/ipv6/conf/<iface>,
NetworkManager is likely alread running, so the change won't take
effect.
- If NetworkManager is restarted it will read the value again, but this
value can be the one set by NetworkManager itself in the last
activation. This means that different values can be used as default in
the same system boot depending on the restarts of NetworkManager.
Moreover, this weird situation might happen:
- Connection A with ip6-privacy=2 is activated
- NetworkManager is stopped. The value in
/proc/sys/net/ipv6/conf/<iface>/use_tempaddr remains as 2.
- NetworkManager starts. It reads from /proc/sys/... and saves the value
'2' as the default.
- Connection B with no ip6-privacy setting is activated. The '2' saved
as default value is used. The connection didn't specify any value for
it, and the value '2' was set by another connection for that specific
connection only, not manually by a user that wanted '2' to be the
default.
A user shouldn't have to think on when NetworkManager starts or restarts
to known in an easy and predictable way what the default value for
certain property is. It's totally counterintuitive.
Revert back to the old behaviour of reading from
/proc/sys/net/ipv6/conf/default. Although this value is used by the
kernel only for newly created interfaces, and not for already existing
ones, it is reasonable to think on these settings as "systemwide
defaults" that the user has chosen.
Note that setting a different default in NetworkManager.conf still takes
precedence.

Replaced by full_path:
https://mesonbuild.com/Reference-manual_returned_external_program.html#external_programpath
ExternalProgram.full_path was added in meson 0.55 but we support meson
>= 0.51. Because of that, use path or full_path conditionally depending
on the meson version.
This gets rid of the following deprecation warning:
NOTICE: Future-deprecated features used:
* 0.48.0: {'module python3'}
* 0.55.0: {'ExternalProgram.path'}
When IPv6 privacy extensions are enabled, by default temporary addresses
have a valid lifetime of 1 week and a preferred lifetime of 1 day.
That's far too long for privacy-conscious users, some of whom want a new
address once every few seconds. Add connection options that correspond
to /proc/sys/net/ipv6/conf/*/temp_valid_lft and
/proc/sys/net/ipv6/conf/*/temp_prefered_lft to allow configuring the
address rotation time on a per-connection basis.
The new properties are defined as 32-bit signed integers to match the
sysctl parameters which are also signed, although currently only
positive numbers are valid.
Introduce a new option to NMSettingIpConfig. The new option is ternary
type being the default value set to disabled. When enabled,
NetworkManager will instruct the DHCP client to send RELEASE message
when IP addresses are being removed.
The new option at NMSettingConnection allow the user to specify if the
connection needs to be down when powering off the system. This is useful
for IP address removal prior powering off. In order to accomplish that,
we listen on "Shutdown" systemd DBus signal.
The option is set to FALSE by default, it can be specified globally on
configuration file or per profile.
Currently the internal DHCP client sets traffic class "CS6" in the DS
field of the IP header for outgoing packets.
dhclient sets the field according to the definition of TOS (RFC 1349),
which was was deprecated in 1998 by RFC 2474 in favor of DSCP.
Introduce a new property IPvX.dhcp-dscp (currently valid only for
IPv4) to specify a custom DSCP value for DHCP backends that support it
(currently, only the internal one).
Define the default value to CS0, because:
- section 4.9 of RFC 4594 specifies that DHCP should use the standard
(CS0 = 0) service class;
- section 3.2 says that class CS6 is for "transmitting packets
between network devices (routers) that require control (routing)
information to be exchanged between nodes", listing "OSPF, BGP,
ISIS, RIP" as examples of such traffic. Furthermore, it says that:
User traffic is not allowed to use this service class. By user
traffic, we mean packet flows that originate from user-controlled
end points that are connected to the network.
- we got reports of some Cisco switches dropping DHCP packets because
of the CS6 marking.

CMP() is a confusing pattern. Sure enough, the sort order was wrong, for
example, `nmcli connection` would show
$ nmcli -f STATE,UUID,DEVICE c
STATE UUID DEVICE
activating 3098c902-c59c-45f4-9e5a-e4cdb79cfe1b nm-bond
activated e4fc23ac-54ab-4b1a-932a-ebed12c96d9b eth1
("activating" shown before "activated").
With `nmcli device`, we sort with compare_devices(). This first sorts by
device state (with "connected" being sorted first). Only when the device
state is equal, we fallback to nmc_active_connection_cmp(). So with
`nmcli device` we usually get "connected" devices first, and we don't
really notice that there is a problem with nmc_active_connection_cmp().
On the other hand, `nmcli connection` likes to sort first via
nmc_active_connection_cmp(), which gets it wrong. Profiles in
"activating" state are sorted first. That's inconsistent with `nmcli
device`, but it's also not what is intended.
Fix that.
Note the change in the test output. Both eth1 and eth0 are connected to
to the same profile, but one "eth0" the active-connection's state is
DEACTIVATING, while on "eth1" it's ACTIVATED (but both device's states
are "CONNECTED"). That's why "eth1" is now sorted first (as desired).
Fixes: a1b25a47b0 ('cli: rework printing of `nmcli connection` for multiple active connections')
- test for "-order" option with `nmcli connection show`.
- test for order of activated devices. Optimally, the devices
should be in activating vs. activated state. I fail to do that,
the mock implementation is cumbersome to use. It still seems useful
to have this (maybe it could be improved).
Adds a new WiFi 6GHz capability flag, NM_WIFI_DEVICE_CAP_FREQ_6GHZ,
along side the existing NM_WIFI_DEVICE_CAP_FREQ_2GHZ &
NM_WIFI_DEVICE_CAP_FREQ_5GHZ flags.
Gnome settings utilizes the 2 existing flags to present supported
bands in gnome-settings. I will be using this additional flag in
modifications there.

When updating NetworkManager to a new version, normally the service is
not restarted by the installer to avoid interrupting networking.
However, next nmcli invocation will use the updated version, but against
the older version of the daemon that is still running. Although this is
suposed to work, it is advisable that nmcli and daemon's versions are
the same. Emit a warning recommending restarting the daemon.
Add nmcli test to check the new feature. To avoid breaking the existing
tests, test-networkmanager-service now reports the same version than the
running nmcli except if it's instructed to report a different one.
