6127aadda6 core: fail early if we cannot get current FEC value
If we cannot get current FEC value probably we won't be able to set it a
few lines later. Also, if it fails to set, we try to use the value of
the old one that we tried to retrieve without success. In that case, the
variable old_fec_mode would be uninitialized. Fix it by returning early
if we cannot get the current value.

ce3d134116 core: prevent the activation of unavailable OVS interfaces only
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.

80158a3764 policy: always reset retries when unblocking children or ports
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.

21cff68a8a core: prevent the activation of unavailable devices
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.

When the kernel don't support mptcp, NetworkManager should disable mptcp

/proc/sys/net/mptcp/enabled, val v's type is defined to guint32, and
nm_platform_sysctl_get_int32 return -1, v becomes a very large number
and can't set mptcp_flags to NM_MPTCP_FLAGS_DISABLED.

Add a function to compare two arrays of NMPlatformBridgeVlan. It will
be used in the next commit to compare the VLANs from platform to the
ones we want to set.

To compare in a performant way, the vlans need to be normalized (no
duplicated VLANS, ranges into their minimal expression...). Add the
function nmp_utils_bridge_vlan_normalize.

f93c008904 device: support reapplying bridge-port VLANs
For now, always reapply the VLANs unconditionally, even if they didn't
change in kernel.

To set again the VLANs on the port we need to clear all the existing
one before. However, this deletes also the VLAN for the default-pvid
on the bridge. Therefore, we need some additional logic to inject the
default-pvid in the list of VLANs.

23ef171a7d bridge: change the signature for nm_platform_link_set_bridge_vlans()
Currently, nm_platform_link_set_bridge_vlans() accepts an array of
pointers to vlan objects; to avoid multiple allocations,
setting_vlans_to_platform() creates the array by piggybacking the
actual data after the pointers array.

In the next commits, the array will need to be manipulated and
extended, which is difficult with the current structure. Instead, pass
separately an array of objects and its size.

7824d5e5ae vpn: fix routing rules support in vpn conenctions
This commit introduces the ability to manage routing rules specifically
for VPN connections. These rules allow finer control over traffic
routing by enabling the specification of policy-based routing for
traffic over the VPN.

- Updated the connection backend to apply rules during VPN activation.
- Ensured proper cleanup of routing rules upon VPN deactivation.

This enhancement improves VPN usability in scenarios requiring advanced
routing configurations, such as split tunneling and traffic
prioritization.

364e6e199c ndisc: honor default route parameters from RA route options
RFC 4191 section-3.1 says:

  When processing a Router Advertisement, a type C host first updates a

  in the Router Advertisement message header. [...] The Router Preference
  and Lifetime values in a ::/0 Route Information Option override the
  preference and lifetime values in the Router Advertisement header.

Fix the RA parsing so that the parameters from a default route option
are applied to the gateway.

f3006bf894 core: fix deleting internal global DNS configuration
The tracking of variable "has_intern" in intern_config_read() is
wrong: we set it when adding any entry to the keyfile, but then we
remove the global DNS section without updating the variable.

The effect is that the function might return an empty keyfile instead
of NULL.

a9b7a8d88e l3cfg: get routes to prune from the list of routes configured by NM
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.

3157504062 l3cfg: remove routes added by NM on reapply
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.

d5e832a3b5 bonding: send ARP announcement on bonding-slb link/carrier down
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.

1fa281351c linux-platform: add helper function to query FDB table
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.

When handling event TIMEOUT, "acd_data->probing_timeout_msec" needs to
be always initialized before jumping to "handle_start_probing:";
otherwise, an assertion failure is triggered at:

  static void
  _l3_acd_data_timeout_schedule_probing_restart(AcdData *acd_data, gint64 now_msec)
  {
    ...
    nm_assert(acd_data->probing_timeout_msec > 0);

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
reached from a INSTANCE_RESET event; and depending on the previous
state "acd_data->probing_timeout_msec" could be uninitialized.

8d8eaca0d0 nmtui: correctly check that connection list is non-empty
Previously, the "edit" or "delete" buttons were clickable even
if there were no available connections, which was not expected
and caused an assertion to fail when clicked. This is because
the connections list could contain connections that were later
filtered out and not displayed in the final list, but the check
did not take this into account.

Make it so that the buttons are clickable only if we *actually*
have any available connections to edit or delete.

317b9a3a9c ovs: fix assertion failure in netdev datapath mode
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.

06032aa758 ndisc: preserve router preferences
If we add multiple default routes with the same metric and different
preferences, kernel merges them into a single ECMP route, with overall
preference equal to the preference of the first route
added. Therefore, the preference of individual routes is not
respected.

To avoid that, add routes with different metrics if they have
different preferences, so that they are not merged together.

We could configure only the route(s) with highest preference ignoring
the others, and the effect would be the same. However, it is better to
add all routes so that users can easily see from "ip route" that there
are multiple routers available.

e4d7cb7453 policy: assert that the auto-activate list is empty on dispose
We are currently asserting that the list of devices waiting for
auto-activation in NMPolicy is not empty. This condition is always
false because:

 - NMDevice holds a reference to NMManager
 - NMManager holds a reference to NMPolicy
 - on dispose, NMDevice asserts that it's not in NMPolicy's
   auto-activate list

Therefore if there is any NMDevice alive, NMPolicy must be alive as
well. Instead, if there is no NMDevice alive the list must be empty.

The assertion could fail only when the NMPolicy instance gets
disposed, which usually doesn't happen because it's still referenced
at shutdown.

19a8feaad6 agent: print error message character in hex form if it's unprintable
Currently, when the agent manager is sent a registration request
containing UTF-8 characters, it will form an invalid error message
using only one of the bytes from the UTF-8 sequence, which causes
an assertion in glib to fail, which replaces the returned error message
with "[Invalid UTF-8]". It will also print an assertion failure to the
console, or crash NetworkManager on non-release builds.

This commit makes it so that it instead prints out the character in
hexadecimal form if it isn't normally printable, so that it is once
again a valid UTF-8 string.

1006b39ef1 wifi: fix list corruption when scanning with explicit SSID
Calling c_list_link_tail() on a list entry that already belongs to
another list corrupts the other list, in this case 'old_lst_head';
this is explained in the documentation of c_list_link_before():

 * @what is not inspected prior to being linked. Hence, it better not
 * be linked into another list, or the other list will be corrupted.

This can be reproduced by invoking "nmcli device wifi rescan ssid x"
multiple times; in this way, _scan_request_ssids_track() reuses the
previous SSID data, the list gets corrupted and this causes a crash.

83c32e9f17 device: fix bug when deactivating port connections asynchronously
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.
