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 227cd6307b)
(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.

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.

(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

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.

(cherry picked from commit 6d06286f1d)
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

the ports failover.
(cherry picked from commit 69f3493670)
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.

We always sync routes in the main table, but routes in tables other
than main are only pruned if were added by NM, by default. Get the list
of routes to prune from other tables using obj_state->os_nm_configured,
as this tracks what routes were effectively added by NM.
The list should be the same that the one obtained from l3cfg_old. It
could be different if we commited the l3cfg with an NMIPRouteTableSyncMode
of NM_IP_ROUTE_TABLE_SYNC_MODE_MAIN, thus not deleting some routes at
commit time. However, since the previous commit, we never do it.
What all this shows is that starting to use different NMIPRouteTableSyncModes
is probably a bad idea: it will be a source of bugs of routes not being
always synced as users expect, and the use case for them is still to be
known.
(cherry picked from commit c06d130c38)
By default, on reapply we were only syncing the main routes table. This
causes that routes added by NM to other tables are not removed on
reapply. This was done to preserve routes added externally, but routes
added by NM itself should be removed.
Add a new route table syncing mode "main + NM routes". This mode
maintains the normal behaviour of syncing completely the main table,
and for other tables removes only routes that were added by us, leaving
the rest untouched. Use this mode by default, as this is what a user
would expect on reapply.
Note: this might not work if NM is restarted between the profile being
modified and the reapply, because NM forgets what routes were added by
itself because of the restart. This is a rare corner case, though.
Use the D-Bus property "VersionInfo" to expose a capability flag
indicating that this bug is fixed. It is the first capability that we
expose in this way. However, it is convenient to do it this way as it's
something that clients like nmstate needs to know, so they can decide
whether a conn down is needed or not. It is not enough to decide that by
version number because it might be fixed via a downstream patch in distros
like RHEL.

When the attach_port()/detach_port() methods do not return immediately
(currently, only for OVS ports), the following situation can arise:
- nm_device_controller_attach_port() starts the attachment by sending
the command to ovsdb. Note that here we don't set
`PortInfo->port_is_attached` to TRUE yet; that happens only after
the asynchronous command returns;
- the activation of the port gets interrupted because the connection
is deleted;
- the port device enters the deactivating state, triggering function
port_state_changed()
- the function calls nm_device_controller_release_port() which checks
whether the port is already attached; since
`PortInfo->port_is_attached` is not set yet, it assumes the port
doesn't need to be detached;
- in the meantime, the ovsdb operation succeeds. As a consequence,
the kernel link is created even if the connection no longer exists.
Fix this by turning `port_is_attached` into a tri-state variable that
also tracks when the port is attaching. When it is, we need to perform
an explicit detach during deactivation.

Even if the ACD data is already in state PROBE, that doesn't mean that
the timeout is already initialized because the PROBE state can also be

When using the netdev datapath, we wait for the link to appear in
different steps:
1. initially, in act_stage3_ip_config() connects to platform's
"link-changed" signal to detect when the TUN interface appears;
2. when the interface appears, _netdev_tun_link_cb() schedules
_set_ip_ifindex_tun() in a idle handler;
3. _set_ip_ifindex_tun() checks if the link is ready (e.g. if the MAC
address is correct) and in that case it reschedules stage3, which
will move forward with the activation;
4. if the link is not ready in _set_ip_ifindex_tun(), the function
connects again to platform's "link-changed" signal to react to link
changes;
5. after the link changes and it is ready, _netdev_tun_link_cb()
reschedules stage3, which moves forward with the activation;
With the current implementation it is possible that after step 2, if
act_stage3_ip_config() runs because it was already scheduled, it
registers again to the "link-changed" event; then when
_set_ip_ifindex_tun() is invoked it will hit assertion:
nm_assert(!priv->wait_link.tun_link_signal_id);
Fix this by preventing that the signal gets registered again after
step 2.
