An IPv6 endpoint is not usable until the address is non-tentative. Add
a mechanism to wait until the address is ready.

(cherry picked from commit ceef38d9a5)
Skip the configuration of the MPTCP endpoint when the address is in
the l3cd but is not yet configured in the platform. This typically
happens when IPv4 DAD is enabled and the address is being probed.
If we configure the endpoint without the address set, the kernel will
try to use the endpoint immediately but it will fail. Then, the
endpoint will not be used ever again after the address is added.

The name suggests that the function always removes all the watchers
with the given tag; instead it removes only "dirty" ones when the
"all" parameter is FALSE. Split the function in two variants.

Preventing the activation of unavailable devices for all device types is
too aggresive and leads to race conditions, e.g when a non-virtual bond
port gets a carrier, preventing the device to be a good candidate for
the connection.
Instead, enforce this check only on OVS interfaces as NetworkManager
just makes sure that ovsdb->ready is set to TRUE.

Fixes: 774badb151 ('core: prevent the activation of unavailable devices')
(cherry picked from commit a1c05d2ce6)
(cherry picked from commit b8ef2a551e)
When calling activate_port_or_children_connections() we are unblocking
the ports and children but we are not resetting the number of retries if
it is an internal activation.
This is wrong as even if it's an internal activation the number of
retries should be reset. It won't interferfe with other blocking reasons
like USER_REQUESTED or MISSING_SECRETS.

(cherry picked from commit 2daeef668d)
When autoconnecting ports of a controller, we look for all candidate
(device,connection) tuples through the following call trace:
-> autoconnect_ports()
-> find_ports()
-> nm_manager_get_best_device_for_connection()
-> nm_device_check_connection_available()
-> _nm_device_check_connection_available()
The last function checks that a specific device is available to be
activated with the given connection. For virtual devices, it only
checks that the device is compatible with the connection based on the
device type and characteristics, without considering any live network
information.
For OVS interfaces, this doesn't work as expected. During startup, NM
performs a cleanup of the ovsdb to remove entries that were previously
added by NM. When the cleanup is terminated, NMOvsdb sets the "ready"
flag and is ready to start the activation of new OVS interfaces. With
the current mechanism, it is possible that a OVS-interface connection
gets activated via the autoconnect-ports mechanism without checking
the "ready" flag.
Fix that by also checking that the device is available for activation.

Rename "unavailable_devices" to "exclude_devices", as the
"unavailable" term has a specific, different meaning in NetworkManager
(i.e. the device is in the UNAVAILABLE state). Also, use
nm_g_hash_table_contains() when needed.
(cherry picked from commit 6c1eb99d32)
Using `n_dhcp4_c_connection_start_request()` will cause staying in
`connection->request`, as a result, it will cause the resending of
DHCPRELEASE and DHCPDECLINE message, thus, use
`n_dhcp4_c_connection_send_request()` directly instead to avoid
unnecessary retransmission timeout, as suggested by
f030927a54 (r1531834009).
(cherry picked from commit 55710d3d7c)
We should not send the DHCP release message when udp socket is still in
the PACKET state, this state is typically used during the discovery and
offer phases, where the client broadcasts DHCP packets like DHCPDISCOVER
and receives responses like DHCPOFFER. At this point, the client has no
lease because it has not yet completed the DHCP handshake.
(cherry picked from commit bccf031591)
In the scenario for sending the release message, we need to guarantee
that NM only sends the release message when the client received a lease
from the server. However, there is some distinction between the
`l3cd_curr` and `l3cd_next` when ACD is pending, because `l3cd_curr` is
NULL but `l3cd_next` is not NULL when ACD is pending. Regardless of
whether ACD is pending or completed, these are all considered the client
have received the release from the server. Therefore, adapt the function
`nm_dhcp_client_get_lease()` to control whether to get next or current
lease.

Old branches tend to be formatted with a different versions of
clang-format, so when patches are backported, they introduce some
differences in formatting, making the check-tree job to fail.
These changes in formatting are normally small, and we don't pay much
attention to them, causing that the pipelines are always red, increasing
the work required to check if there are important failures or not.
Make check-tree optional for branches other than main. This way,
failures will be shown as a "warning", and if a pipeline only shows a
warning we don't need to inspect it.

When a bond in balance-slb is created, the ports are enabled or disabled
based on carrier and link state. If the link/carrier goes down, the port
becomes disabled and we must make sure the MAC tables of the switches
are updated properly so the traffic is redirected.
In order to solve this, we send a GARP or RARP broadcast packet on the
bond. This fix cover 3 different balance-slb scenarios.
Scenario 1: The bond in balance-slb mode has IPv4 address configured and
some ports connected. Here the bond is acting like active-backup as the
packets will always have as source MAC the address of the bond
interface. When a port goes down, NetworkManager will send a GARP
broadcast announcing the address configured on the bond with the MAC
address configured on the port.
Scenario 2: The bond in balance-slb mode is connected to a bridge and has
some ports connected. The bridge has IPv4 configured. When a port goes
down, NetworkManager will send a GARP broadcast announcing the address
configured on the bridge with the MAC address configured on the port.
Scenario 3: The bond in balance-slb mode is connected to a bridge and
has some ports connected. The bridge does not have IP configuration and
therefore everything is L2. When a port goes down, NetworkManager will
query the FDB table and filter the entries by the ones belonging to the
bridge and the bond ifindexes. Then, it will send a RARP broadcast
announcing every learned MAC address from FDB.
Fixes: e9268e3924 ('firewall: add mlag firewall utils for multi chassis link aggregation (MLAG) for bonding-slb')
(cherry picked from commit 3f2f922dd9)
The function introduced queries the FDB table via netlink socket. It
accepts a list of ifindexes to filter out the FDB content not related to
it. It returns an array of MAC addresses.
To cltarify this function is unusually exposed directly on
nm-linux-platform.h as we don't want this be part of the whole
NMPlatform object or cache. This, is an exception to the rule to
simplify the integration of this functionality on NetworkManager.
In addition, it also doesn't use the async mechanism that is widely used
on netlink communication across nm-linux-platform. Again, the reason is
to simplify its use, as async communication won't provide a benefit to
the use cases we have planned for this, i.e balance-slb RARP announcing.

This function would be useful when performing operations related to the
IPv4 addresses configured on the l3cfg. E.g this function will be used
for getting the IPv4 to announce on a GARP on bonding-slb when one of
the ports failover.

The regex for "Fixes" also matches with "Ignore-Fixes", so the commit is
added twice and then removed only once by the "Ignore-Fixes". It still
remains once in the list of commits to backport, making that
"Ignore-Fixes" does not work. Fix it.
Now we are using scheduled pipelines for various purposes like
regenerating the container images and triage the issues and MRs. That
means that the last pipeline ran for main might not be the pipeline with
the jobs building and testing the code.
Use `source=push` to retrieve only pipelines that are not scheduled.
The help text is read from the comments at the top of the script itself.
However, to detect what lines belongs to the help text, a range was
defined as:
- Start: any line starting with `# `
- End: any line starting `# Run with --no-test`
If any later line starts with `# ` is considered as a new matching
range, and from it to the end of the file is printed too.
Fix it by defining the range:
- Start: line 2
- End: blank line
GNOME has changed the process to publish releases to download.gnome.org.
Now, it is required to do it from the CI of projects hosted in GNOME's
repositories.
As we don't have the project hosted there, we have 2 options:
- Create a mirror and set up the CI so we continue using
download.gnome.org.
- Stop publishing the tarballs there and do it in gitlab.freedesktop.org
from now on.
After a brief discussion we have decided that the second makes more
sense, so adapt release.sh to do that.

After upgrading to RHEL-9.4, customers have reported that `ip monitor`
repeatedly logs the same route additions every 30 seconds. This issue
appears to stem from NetworkManager continually retrying to add the same
routes due to keep retrying Address Conflict Detection (ACD) on NOARP
interfaces.
To prevent unnecessary route additions and reduce log noise, this change
modifies NetworkManager's behavior to stop retrying ACD on interfaces
with the NOARP flag.
This fix addresses route instability and excessive logging for affected
NOARP configurations.
