The function checks that priv->wait_link.waiting is set. Since the
flag is only set in stage3, it is wrong to schedule stage2 again.

Also, add prefix "ovs-wait-link" to all messages related to waiting
for the ovs link, so that they can be easily spotted in logs.

The code to determine if we are using the netdev datapath is logically
separated from the code to start IP configuration; move it to its own
function to make the code easier to follow.
(cherry picked from commit a7a06163be)
The deactivation can happen while we are waiting for the ifindex, and
it can happen via two code paths, depending on the state. For a
regular deactivation, method deactivate_async() is called. Otherwise,
if the device goes directly to UNMANAGED or UNAVAILABLE, deactivate()
is called. We need to make sure that signal and source handlers are
disconnected, so that they are not called at the wrong time.

This reverts commit 05c31da4d9.
In the linked commit the callback was made repeating on the assumption
that forward progress would result in the callback getting canceled in
cb_data_complete. However, this assumption does not hold since a timeout
callback does not guarantee completion (or error out) of a request.
curl tweaked some internals in v8.4.0 and started giving 0 timeouts, and
a repeating callback is firing back-to-back without making any progress
in doing so.
Revert the change and make the callback non-repeating again.

Previously, we first sort by the device's state, then by the active
connection's state. Contrast to `nmcli connection`, which first sorts
by the active connection's state.
It means, the sort order is somewhat different. Fix that.
In most cases, that shouldn't make a difference, because the
device's state and the active-connection's state should
correspond. However, it matters as we now treat external activations
different, and that is tied to the active connection.
(cherry picked from commit 38ad9e5211)
EXTERNAL connections are special. Sort them later. This affects output
of `nmcli connection` and `nmcli device`.
(cherry picked from commit a5f9f2fbfc)
Additional logic will be added, that makes the switch() approach
more cumbersome. Use a sorted array instead to find the priority.
(cherry picked from commit 8ccd1f7bfe)
CMP() is a confusing pattern. Sure enough, the sort order was wrong, for
example, `nmcli connection` would show
$ nmcli -f STATE,UUID,DEVICE c
STATE UUID DEVICE
activating 3098c902-c59c-45f4-9e5a-e4cdb79cfe1b nm-bond
activated e4fc23ac-54ab-4b1a-932a-ebed12c96d9b eth1
("activating" shown before "activated").
With `nmcli device`, we sort with compare_devices(). This first sorts by
device state (with "connected" being sorted first). Only when the device
state is equal, we fallback to nmc_active_connection_cmp(). So with
`nmcli device` we usually get "connected" devices first, and we don't
really notice that there is a problem with nmc_active_connection_cmp().
On the other hand, `nmcli connection` likes to sort first via
nmc_active_connection_cmp(), which gets it wrong. Profiles in
"activating" state are sorted first. That's inconsistent with `nmcli
device`, but it's also not what is intended.
Fix that.
Note the change in the test output. Both eth1 and eth0 are connected to
to the same profile, but one "eth0" the active-connection's state is
DEACTIVATING, while on "eth1" it's ACTIVATED (but both device's states
are "CONNECTED"). That's why "eth1" is now sorted first (as desired).
Fixes: a1b25a47b0 ('cli: rework printing of `nmcli connection` for multiple active connections')
(cherry picked from commit 8e1330964d)
- test for "-order" option with `nmcli connection show`.
- test for order of activated devices. Optimally, the devices
should be in activating vs. activated state. I fail to do that,
the mock implementation is cumbersome to use. It still seems useful
to have this (maybe it could be improved).

If a commit is invoked without any change to the l3cd or to the ACD
data, in _l3cfg_update_combined_config() we skip calling
_l3_acd_data_add_all(), which should clear the dirty flag from ACDs.
Therefore, in case of such no-op commits the ACDs still marked as
dirty - but valid - are removed via:
_l3_commit()
_l3_acd_data_process_changes()
_l3_acd_data_prune()
_l3_acd_data_prune_one()
Invoking a l3cfg commit without any actual changes is allowed, see the
explanation in commit e773559d9d ('device: schedule an idle commit
when setting device's sys-iface-state').
The bug is visible by running test 'bond_addreses_restart_persistence'
with IPv4 ACD/DAD is enabled by default: after restart IPv6 completes
immediately, the devices becomes ACTIVATED, the sys-iface-state
transitions from ASSUME to MANAGED, a commit is done, and it
incorrectly prunes the ACD data. The result is that the IPv4 address
is never added again.
Fix this by doing the pruning only when we update the dirty flags.
This is a respin of commit ed565f9146 ('l3cfg: fix pruning of ACD
data') that was reverted because it was causing a crash. The crash was
caused by unconditionally clearing `acd_data_pruning_needed` in
_l3cfg_update_combined_config(), while we need to do it only when
actually committing the configuration.

This reverts commit ed565f9146.
(cherry picked from commit 6a63d79fe6)
It seems more useful to have a best effort approach and configure
everything we can; in that way we achieve at least some connectivity,
and then sysadmin can check the logs in case something is
missing. Currently instead, the whole activation fails (so, no address
is configured) if just one of the addresses fails DAD.
Ideally, we should have a way to make this configurable; but for now,
implement the more useful behavior as default.

Clarify that the value is the *maximum* interval; the actual value is

(cherry picked from commit 536805231a)
IPv4 and IPv6 DAD work slightly differently: for IPv4 the presence or
absence of carrier doesn't have any effect on the duration of the
probe; for IPv6, DAD never completes without carrier because kernel
never removes the tentative flag.
In both cases, we shouldn't ignore the DAD result because that would
mean that we complete the ipmanual method without addresses actually
configured.

We don't know the reason why the DHCP client is being stopped. It is
wrong to schedule a commit of type "update" because the device could

Interfaces with IFF_NOARP don't support Address Conflict Detection,
which is based on ARP. Trying to start ACD on them would result in
ENOBUFS always being returned by send(), and n-acd handles such error
by retrying indefinitely.

(cherry picked from commit 7548ff57d3)
On interfaces not supporting ACD (for example, layer3 interfaces), the
probe fails to be created with message:
l3cfg[...,ifindex=2]: acd[172.25.17.1, init]: probe-good (interface does not support acd, initial post-commit)
l3cfg[...,ifindex=2]: acd[172.25.17.1, ready]: set state to ready (probe is ready, waiting for address to be configured)
During the post-commit event, if the address is not yet configured, we
need to schedule a new commit to actually add it.

(cherry picked from commit 687051368f)
Currently, all the probes of an acd instance share the same seed
state. This means that the state is updated by all the probes, and as
a consequence they get different jitters for the wait timeouts;
therefore the order in which addresses become available (and are
configured on the interface) is not deterministic.
Keep a separate seed state for each probe, initialized from the acd
seed. This ensures that all the probes use the same timeouts when
sending probe requests, and that in case of no collision, addresses
are available in the order of probe start.

If the device is being disconnected for a user request, at the moment
the active connection goes to state DEACTIVATED through the following
transitions, independently of the reason for the disconnection:
- state: DEACTIVATING, reason: UNKNOWN
- state: DEACTIVATED, reason: DEVICE_DISCONNECTED
For VPNs, a disconnection is always user-initiated, and the active
connection states emitted are:
- state: DEACTIVATING, reason: USER_DISCONNECTED
- state: DEACTIVATED, reason: USER_DISCONNECTED
This difference poses problems for clients that want to handle device
and VPNs in the same way, especially because WireGuard is implemented
as a device, but is logically a VPN.
Let NMActRequest translate the USER_REQUESTED device state reason to
USER_DISCONNECTED active connection state reason, in case of
disconnection.
This is an API change, but the previous behavior of reporting generic
uninformative reasons seems a bug. See for example
nmc_activation_get_effective_state(), which inspects the AC state
reason and in case it's generic (DEVICE_DISCONNECTED), it considers
the device state instead.
