When looking for the dnsmasq (or any) binary, NetworkManager should check /usr/local before it checks any system installed version. This allows the user to replace the binary with a newer version should they desire and is more consistent with the search behaviour commonly found in $PATH.

The unmanaged flags PLATFORM_INIT indicates whether UDEV is done
initializing the device. We should not handle IP config changes
before that pointer.

This avoids codepaths that require the permanent MAC address of the
device. We should not freeze the permanent MAC address before
UDEV initialized the device, for two reasons:

- getting the permanent MAC address using ethtool is racy as
  UDEV might still rename the interface.
- freezing a fake permanent MAC address should only happen after
  UDEV is done configuring the MAC address of software devices.

The unmanaged flags PLATFORM_INIT indicates whether UDEV is done
initializing the device. We should not handle IP config changes
before that pointer.

This avoids codepaths that require the permanent MAC address of the
device. We should not freeze the permanent MAC address before
UDEV initialized the device, for two reasons:

- getting the permanent MAC address using ethtool is racy as
  UDEV might still rename the interface.
- freezing a fake permanent MAC address should only happen after
  UDEV is done configuring the MAC address of software devices.

If the device is disconnected because it can't be assumed due to lack
of IP configuration, don't try to generate an ipv6 link-local address,
as this requires a connection.

I got an assertion failure:
    wifi_secrets_cb: assertion 'nm_device_get_state (device) == NM_DEVICE_STATE_NEED_AUTH' failed
with backtrace [1].

I think, we have to keep track of the pending secrets request
and cancel it when the device state changes.

I got an assertion failure:
    wifi_secrets_cb: assertion 'nm_device_get_state (device) == NM_DEVICE_STATE_NEED_AUTH' failed
with backtrace [1].

I think, we have to keep track of the pending secrets request
and cancel it when the device state changes.

When a VPN connection can't be activated we have to unexport and
dispose it. Commit f2182fb ("core: don't emit double
PropertiesChanged signal for new active connections") removed the call
to nm_exported_object_unexport() in case of failure because the active
connection already gets unreferenced on failure.

However, an exported object can't be disposed until it's explicitly
unexported because GDBus code keeps a reference to it. The result was
that the active connection was kept alive and exported, but without
explicit references to it. As soon as the connection was unexported,
it was also automatically disposed, causing issues like:

do a check on parent ifindex before calling "nm_device_supports_vlans"
otherwise if the parent device is a software device and its ifindex
member has not been updated yet we will trigger the g_return_if_fail
statement in "nmp_cache_lookup_entry_link".

This has been osserved in NetworkManager CI test suite, on NetworkManager
boot, during the creation of a vlan on top of a bond interface.

It seems the assert there is too strict. I don't really understand why
it fails, but I also don't see why the assert is supposed to hold.
Just return in case the device is unmanagable at this point.

The activation shall fail later.

When NM is restarted and a new object-manager is created, ensure that
signal handlers are disconnected from the old one.

Fixes the following:
  assertion failed: (object_manager == priv->object_manager)

If the ovs interface goes away, the ifindex gets zeroed out and l3cfg is
cleaned. Avoid starting ac6 in that case -- add checks similar to what
we do for ll6.

Bad things happen otherwise:

Above is a stack trace of commit af00e39 ('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.

If the ovs interface goes away, the ifindex gets zeroed out and l3cfg is
cleaned. Avoid starting ac6 in that case -- add checks similar to what
we do for ll6.

Bad things happen otherwise:

If the ovs interface goes away, the ifindex gets zeroed out and l3cfg is

The ACD state handling is unfortunately very complicated. That is, because
we obviously need to track state about how ACD is going (acd_data, and in
particular NML3AcdAddrState). Then there are various things that can
happen, which are the AcdStateChangeMode enums. All these state-changes
are then in one function: _l3_acd_data_state_change(), which is
therefore complicated (I don't think that it would become simpler by
spreading this code out to different functions, on the contrary).
Anyway.

So, what happens when we need to reset the n-acd instance? For example,
because the MAC address of the link changed or some error. I guess, we
need to restart probing.

Previously, I think this was not handled properly. We already tried to
fix this several times, the last was commit b331606 ('l3cfg: on
n-acd instance-reset clear also ready ACD state'). There is still an
issue ([1]).

The bug [1] is, that we are in state NM_L3_ACD_ADDR_STATE_READY, during
 ACD_STATE_CHANGE_MODE_TIMEOUT event. That leads to an assertion
failure.

That can only happen, (I think) when we scheduled the timeout
during an earlier ACD_STATE_CHANGE_MODE_INSTANCE_RESET event. Meaning,
we need to handle instance-reset better.

Instead, during instance-reset, switch always back to state PROBING, and
let the timeout figure it out.

happen, which are the AcdStateChangeMode enums. All these state-changes
come together in one function: _l3_acd_data_state_change(), which is
therefore complicated (I don't think that it would become simpler by
spreading this code out to different functions, on the contrary).
Anyway.

So, what happens when we need to reset the n-acd instance? For example,
because the MAC address of the link changed or some error. I guess, we
need to restart probing.

Previously, I think this was not handled properly. We already tried to
fix this several times, the last was commit b331606 ('l3cfg: on
n-acd instance-reset clear also ready ACD state'). There is still an
issue ([1]).

The bug [1] is, that we are in state NM_L3_ACD_ADDR_STATE_READY, during
 ACD_STATE_CHANGE_MODE_TIMEOUT event. That leads to an assertion
failure.

  #10 g_main_context_dispatch (context=0x5629adc6da00) at ../glib/gmain.c:4055

That can only happen, (I think) when we scheduled the timeout
during an earlier ACD_STATE_CHANGE_MODE_INSTANCE_RESET event. Meaning,
we need to handle instance-reset better.

Instead, during instance-reset, switch always back to state PROBING, and
let the timeout figure it out.

We can get a platform signal for any number of reasons. In particular,
we can get a signal that the object exists in platform, while the object
is tracked as zombie.

"Zombies" are objects that we once actively configured, but now no
longer and thus need to remove them. We remember that we need to delete
the object in kernel.

The assertion was wrong. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially.

We can get a platform signal for any number of reasons. In particular,
we can get a signal that the object is present in platform, while the object
is tracked as zombie.

"Zombies" are objects that were actively configured by NetworkManager, but
now no longer and thus will need to be removed. We remember them as objects
that we need to delete.

The assertion was wrong. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially. If we get a signal that the
object exists while being a zombie, that is fine and not something to
handle specially.

…oved_track()

We can get a platform signal for any number of reasons. In particular,
we can get a signal that the object is present in platform, while the object
is tracked as zombie.

"Zombies" are objects that were actively configured by NetworkManager, but
now no longer and thus will need to be removed. We remember them as objects
that we need to delete.

The assertion was wrong. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially. If we get a signal that the
object exists while being a zombie, that is fine and not something to
handle specially.

When cloud-init job (metadata service crawler) starts, it sends the
SIGTERM signal to nm-cloud-setup and force the nm-cloud-setup to
restart, however, because the error is not initialized as NULL in
`_init_start_cancelled_cb()` before it is set, nm-cloud-setup will hit
a dumped core.

TO fix it, initialize the error as NULL in `_init_start_cancelled_cb()`.
