During the deactivation of ovs interfaces, ovsdb receives the command to
remove the interface but for OVS system ports the device won't
disappear.
When reconnecting, ovsdb will update first the status and it will notice
that the OVS system interface was removed and it will set the status as
DEACTIVATING. This is incorrect if the status is already DEACTIVATING,
DISCONNECTED, UNMANAGED or UNAVAILABLE because it will block the
activation of the interface.

NMSettingOvsDpdk does not have a verify() implementation that would prevent
the devargs property from being NULL. We must thus anticipate and handle
a NULL value.

We need to first free "priv->bzobjs", which then will unlink all bzobjs
from the lists. The assert needs to go after.

Above is a stack trace of commit af00e39dd2 ('libnm: add NMIPAddress
and NMIPRoute dups backported symbols from 1.30.8').
As workaround, ignore the ndisc signal, if we currently don't have an ifindex.
Also, recreate the NMIP6Config instances, if the ifindex doesn't match
(or we don't have one).
This workaround is probably good enough for the stable branch, as the
code on main (1.35+) was heavily reworked and the fix does not apply
there.

When the device gets realized, similar to the situation that the device
is unmanaged by platform-init, if the device is still unmanaged by
parent and we clear the assume state. Then, when the device becomes
managed, NM is not able to properly assume the device using the UUID.
Therefore, we should not clear the assume state if the device has only
the NM_UNMANAGED_PLATFORM_INIT or the NM_UNMANAGED_PARENT flag set
in the unmanaged flags.
The previous commit 3c4450aa4d ('core: don't reset assume state too
early') did something similar for NM_UNMANAGED_PLATFORM_INIT flag only.

String properties in libnm's NMSetting really should have NULL as a
default value. The only property that didn't, was "dcb.app-fcoe-mode".
Change the default so that it is also NULL.
Changing a default value is an API change, but in this case probably no
issue. For one, DCB is little used. But also, it's not clear who would
care and notice the change. Also, because previously verify() would reject
a NULL value as invalid. That means, there are no existing, valid profiles
that have this value set to NULL. We just make NULL the default, and
define that it means the same as "fabric".
Note that when we convert integer properties to D-Bus/GVariant, we often
omit the default value. For string properties, they are serialized as
"s" variant type. As such, NULL cannot be expressed as "s" type, so we
represent NULL by omitting the property. That makes especially sense if
the default value is also NULL. Otherwise, it's rather odd. We change
that, and we will now always express non-NULL value on D-Bus and let
NULL be encoded by omitting the property.
The settings plugin is not supposed to normalize the profile. It should
read/write what is, and let NMConnection handle what is valid and what
needs normalization.
Give a consistent name.
A bit odd are now the names nm_g_bytes_hash() and nm_g_bytes_equal()
as they go together with nm_pg_bytes_hash()/nm_pg_bytes_equal().
But here the problem is more with the naming of "nm_p*_{equal,hash}()"
functions, which probably should be renamed to "nm_*_ptr_{equal,hash}()".
LLD 13 adds -z start-stop-gc and makes it the default, resulting in:

There are routers out in the wild which won't send unsolicited
router advertisements.
In the past, these setups still worked because NetworkManager
used to send router solicitations whenever the half-life of
dns servers and dns domains expired, but this has been changed
in commit 03c6d8280c ('ndisc: don't call solicit_routers()
from clean_dns_*() functions').
We will now schedule router solicitation to be started again
about one minute before advertised entities expire.

We have "ipv[46].may-fail", which are per-address family. This works
together with nm_l3cfg_check_ready(), where we check whether an
NML3ConfigData is ready. We need to have that check also per-address
family.
The MASTER property must be emitted on the port; while PORTS and
SLAVES on the controller.

Drop a workaround added by commit a8ca7f537d ('ppp: work around PPP
bug that returns bogus nameservers'), in 2009.
Also drop the second workaround (`if (!num ...`), which was introduced
by commit 294a5e3153 ('modem: substitute known-good nameservers if PPP
doesn't return any (lp:434477)').
I hope this doesn't break something, but it really doesn't seem right in

- add "pre-commit" signal.
- fix assertion in nm_l3_config_data_get_ip6_privacy().
- set IPv6 privacy in _init_from_connection_ip() from profile.
- fix leaking "os_zombie_lst" in _obj_state_data_free().
- remove wrong assertion about VRF.
- fix _routes_temporary_not_available_update() to honor only the
requested object type. Otherwise, we always prune unrelated objects
too.
We might want to schedule a last update and unref the NML3Cfg instance.
We need to make sure that the last update gets processed. Do that by
taking a reference while an idle source is pending.
The property `PROP_PORTS` should be of type g_param_spec_variant() with
variant 'ao'. This way the variant can be cached.
The deprecated property 'device::slaves' in
'src/core/devices/nm-device.c' must have the same getter-implementation,
returning the same GVariant instance.

"nm_assert(_self->priv.p->combined_l3cd_commited)" might fail during deactivate.
At that point the combined/commited config is NULL, but we still have zombies.
We often want to be pedantic about not accepting %NULL for getters (or ref,
unref, etc). Often that is also inconvenient, so we would need to write:
if (l3cd)
strv = nm_l3_config_data_get_nameservers(l3cd, addr_family, &len);
else
len = 0;
(and, make sure that strv does not trigger a maybe-uninitialized warning).
Being pedanic here is more cumbersome than helpful. Accept NULL to return
the sensible default.
Also add nm_l3_config_data_get_dns_priority_or_default() helper which maps
NULL or a missing value to zero. This is also only for convenience for certain
callers.
The idea was that NMIPConfig would register itself with the property (like "address-data")
and then NML3Cfg would emit the property changed notification.
However, we can already achive that via the regular notification, in particular
by listening to NM_L3_CONFIG_NOTIFY_TYPE_PLATFORM_CHANGE_ON_IDLE notification.
Also, NML3Cfg does not really understand the details when the property should
be emitted. For example, many routes not not exposed via "route-data" property,
and changes to those should not trigger a notification.
Drop the unused API.
With nm_l3cfg_get_combined_l3cd(), we can get the commited or
the combined (next) l3cd. The commits is easy, it's cached already.
However, the combined needs to be computed first, if there were any
changes. For that we call _l3cfg_update_combined_config(), which then
also calls nm_l3_config_data_merge().
But in non-commit mode, _l3cfg_update_combined_config() doesn't call
_l3_acd_data_add_all(), so in _l3_hook_add_obj_cb() the ACD data may
not be as expected. This can previously hit an assertion.
Seems we can get a DOWN event during unit tests. I don't really
understand why, but let's ignore it.

We have nm_l3cfg_commit(), however that is synchronous and triggers an
avalanche of side effects. So it should be avoided if a component is
not aware of the current circumstances in which it gets called (most of them).
The alternative is nm_l3cfg_commit_on_idle_schedule(), but previously
that only supported the auto type.
Two changes:
- add a commit_type parameter to nm_l3cfg_commit_on_idle_schedule().
This allows to explicitly select a type for the next commit.
Previously, if the caller wanted for example to trigger a reapply
once, they had to register a handle, trigger the commit and unregister
the handle again. This basically allows to specify an ad-hoc commit
type that is only used once.
- if an explicit commit type is requested, then still always combine
it with auto. That means, we always use the "maximum" of what is
requested and what is registered.
