This property allows the user to optionally configure
an interlink name on a HSR interface, so that it could
serve as RedBox (Redundant Box) by connecting DAN (dual
attachment node) to SAN (single attachment node).

Uses the `hsr.protocol-version` property defined in the previous
commit to configure the property in the kernel.
(cherry picked from commit 0b99629278)
This property allows the user to set the protocol
version when using HSR. Currently, the property
supports two values - `2010` (referred to as HSRv0
in the kernel), and `2012` (HSRv1).
(cherry picked from commit 9a2395c779)
Adds support for reapplying the `sriov.vfs` property. Note this
does not include `num_vfs`, as the configuration needs to be reset
and reconfigured from scratch in that case.
Previously, if an existing VF is modified (e.g. if we change the `trust`
flag), we reset all VF configurations, and started from scratch. But in
some cases, this is unnecessarily disruptive.

Document a known limitation that we delete bridges and ports from ovsdb
when we remove their last NM-owned attached port or interface, even if
other externally added ports or interfaces exist.
(cherry picked from commit 86ea2c5963)
The commit linked below introduced a bug that caused that OVS ports
added externally to NM are always deleted when we delete any OVS
interface. It affects to all externally added ports, including those
that are not related to the deleted interface and even those in
different OVS bridges.
Fix it by only modifying ports and bridges that are ascendants of the
deleted interface, leaving everything else untouched.
Note that bridges and ports still need to have at least one NM-managed
interface, otherwise they will also be purged. For example, an NM-owned
OVS bridge with 2 ports+iface, one NM-owned and one external: if we
delete the NM-owned iface, both ports and the bridge will be deleted.
For now, this is a known limitation that is not being fixed here.

During disposal we're calling to remove_all_aps that in turns schedules
an auto-activate recheck. As the device is removed, this triggers an
assertion when trying to do the recheck.
Fix that by not scheduling the recheck.

(cherry picked from commit 3904135150)
In some cases it is necessary to set a custom DHCP client-id during
early boot. For example, the firmware of some InfiniBand NIC uses a
48-bit MAC derived from the InfiniBand 20-byte MAC when doing
PXE. NetworkManager doesn't have any knowledge of that 48-bit MAC and
uses the full MAC as client-id, therefore getting a different lease.
Introduce a new option 'rd.net.dhcp.client-id' to specify a custom
client-id.

(cherry picked from commit 40aa27690c)
When reading NetworkManager.conf and NetworkManager-intern.conf we might
need to know if a group is defined or not, even if it's empty. This is
the case, for example, for [global-dns]. If [global-dns] is defined in
NM.conf overwrites the config from NM-intern, and if it's defined in any
of them they overwrite the configs from connections.
Before this patch, defining it as an empty group was ignored:
```
[global-dns]
```
Instead, it was necessary to add at least one key-value to the group.
Otherwise the group was silently ignored.
```
[global-dns]
searches=
```
Keep empty groups so we can take better decissions about overwritting
configs from other sources.
(cherry picked from commit 4a46f454da)
Clients like nmstate needs to know if the [global-dns] section is
defined or not, so they know if DNS configs from connections are
relevant or not. Expose it in D-Bus by always exposing "searches"
and "options" if it's defined, maybe as empty lists.
(cherry picked from commit 7fb4724efa)
According to the documentation, settings from [global-dns] (searches and
options) are always merged with those from connections. However this was
not happening if no [global-dns-domain-*] exists, in which case
connections were ignored. This happened because in the past both global
sections must de defined or undefined. When this was changed to allow
defining only [global-dns], allowing it in the function that generates
the resolv.conf file was forgotten. Fix that now.
Anyway, merging these configs doesn't make much sense. The searches and
options defined in connections probably make sense only for the nameservers
defined in that same connection.
Because of this, make the following change: if global nameservers are
defined, use searches and options from [global-dns] only, because those
defined in connections may not make sense for the global nameservers. If
[global-dns] is missing, assume an empty [global-dns] section.
Also, if no global nameservers are defined, but [global-dns] is, make
that it overwrites the searches and options defined in connections. This
is not ideal, but none of the alternatives is better and at least this
is easy to remember.
So, the resulting rules from above are:
- If [global-dns] is defined, it always overwrite searches and options
from connections.
- If [global-dns-domain-*] is defined, it always overwrite nameservers
from connections. It overwrites searches and options too.

Fixes: f57a848da5 ('man: update documentation about global DNS configuration')
(cherry picked from commit 1cba0a3cca)
Since 1.44 we accept a global-dns section without any global-dns-domain
section, so users can define searches and options without defining any
global DNS servers.
When set from the D-Bus API it was still rejected. Fix it.

(cherry picked from commit 9c48bae3b2)
Unrealized software devices are always available for activation,
hardware devices never.
In nm_manager_get_best_device_for_activation() we call
nm_device_is_available() on candidate devices. Without this fix, any
unrealized software device would be not considered ready for
activation, which is wrong.
A software device can override the default implementation of
is_available(). For example NMDeviceOvsInterface does that and only
checks the OVSDB is ready.

(cherry picked from commit 5ad712974e)
When a software device becomes deactivated, we check whether it can
be unrealized (= deleted in kernel), by calling function
delete_on_deactivate_check_and_schedule().
The function returns without doing anything if there is a new
activation enqueued on the device (priv->queued_act_request), because
in that case the device will be reused for the next activation.
This commit fixes a problem seen in NMCI test
@ovs_delete_connecting_interface: sometimes the device is not
unrealized after deleting the connection. That happens because if the
queued activation fails, we never try again to unrealize the device.
Fix that by calling delete_on_deactivate_check_and_schedule() when
there is a failure starting the queued activation.

(cherry picked from commit dce149352d)
There are several flags specified in the NVMe Boot Specification
that may indicate DHCP was used to acquire information during the
pre-OS phase. This commit considers these additional sources,
based on actual NBFT table contents from different systems.
Although we've seen slight variations in firmware implementations
regarding the HFI IP Origin values when DHCP was configured, the
new set of rules still align with expectations.

acd_data->probing_timestamp_msec indicates when the probing
started. It is used in different places to calculate the timeout for
certain operations. In particular, it is used to detect that the probe
creation took too long when handling the ACD_STATE_CHANGE_MODE_TIMEOUT
event.
If we reset this timestamp at every timer event, we'll never hit the
probe creation timeout. Therefore, the l3cfg will keep trying forever
to create the probe.

The DHCP search list option (119) can use the "message compression"
algorithm specified in RFC 1035 section 4.1.4 to reduce the size of
the message in presence of subdomains that appear multiple times.
When using the compression a label starts with:
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
| 1 1| OFFSET |
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
where the offset points to a previous domain.
Previously, the parsing code was taking the lower 6 bits of the first
byte, shifting them left 16 bits, and adding the next byte. Instead,
the shift should be of 8 bits.
The effect of this bug was that when the offset was greater than 255,
it was incorrectly parsed as a number larger than the message size,
and the parsing failed.
Note that while a single DHCP option can be at most 255 bytes, a DHCP
message can contain multiple instances of the same option. The
receiver must concatenate all the occurrences according to RFC 3396
and parse the resulting buffer.
