fcc81dece3 device: don't reapply IP configuration if the ifindex is missing
Assertions will fail in ip_config_merge_and_apply() if the device

1f97ad8f56 ovs: check state before starting ip configuration after link change
When the link becomes available, check that the device is in the
ip-config state before starting ip configuration. Also, reset the
'waiting_for_interface' flag when the device deactivates.

50bae00473 device: don't transition assumed devices to FAILED before ACTIVATED
If the activation of an assumed device fails, we first set the device
state to FAILED and then to ACTIVATED. In the FAILED state, the active
connection transitions to DEACTIVATED and clears its device pointer;
hence we end up with an inconsistent state which causes assertion
failures in other parts of the code (for example, get_best_ip_config()
assumes that the device of the best active connection is not NULL).

Don't first transition to FAILED and then to ACTIVATED, just set the
latter.

5a4a5f637b ovs: allow changing mac address of bridges and interfaces
Allow changing the cloned MAC address for OVS bridges and
interfaces. The MAC address set on the bridge is propagated by ovs to
the local interface (the one with the same name as the bridge), while
all other internal interfaces use the address defined in the interface
connection.

634067732e ethernet: wait for carrier before starting supplicant
After we set link parameters (auto-negotiation, speed, duplex) in
stage1, the carrier can go down for several seconds because the
Ethernet PHY needs to renegotiate the link. Wait that carrier goes up
before starting the supplicant or the EAPoL start packet can be lost
causing an authentication failure.

84c0e384f4 device: check for disconnected state before activating NMActRequest
When a new activation request comes and the device is currently
activated, we move the device state to 'deactivating' and wait that it
reaches 'disconnected' before starting the new activation request.

In the meantime, a carrier change could happen but still we have to
wait that device finishes any pending deactivation.

1f3b342ad4 platform: avoid compiler error passing NMP_OBJECT_CAST_OBJ_WITH_IFINDEX() to nm_hash_update_vals()
Clang (3.4.2-9.el7) on CentOS 7.6 fails related to nm_hash_update_vals().

Clang seems to dislike passing certain complex arguments to typeof().
I'd prefer to fix nm_hash_update_vals() to not have this problem,
but I don't know how.

This works around the issue.

1ff0ba0fab platform: make nm_platform_kernel_support_get() macro an inline function
clang (3.4.2-9.el7) on CentOS 7.6 fails related to nm_hash_update_vals().

I am not even quoting the error message, it's totally non-understandable.

nm_hash_update_vals() uses typeof(), and in some obscure cases, clang dislikes
when the argument itself is some complex macro. I didn't fully understand why,
but this works around it.

I would prefer to fix nm_hash_update_vals() to not have this limitation.
But I don't know how.

There is probably no downside to have this an inline function instead of
a macro.

07ccf36ed0 platform/tests: rename platform's "test-general.c"
Older versions of meson don't like building multiple artifacts
with the same name (even if they are in different directories). We
have multiple tests called "test-general.c", and it would be natural
to compile a test binary of the same name.

  Meson encountered an error in file src/tests/meson.build, line 14, column 2:
  Tried to create target "test-general", but a target of that name already exists.

It's generally a bad idea to have in our source tree multiple files with the
same name. Rename the test.

0f1900b4f7 build/meson: rename platform tests to use same name as autotools
First of all, all file names in our source-tree should be unique. We should
not have stuff like "libnm-core/tests/test-general.c" and "src/tests/test-general.c".
The problem here are the C source files, and consequently also the test
binaries have duplicate names. We should avoid that in general. However,
our binaries should have a matching name with the C source. If
"test-general.c" is not good enough, that needs renaming. Not building
"platform-test-general" out of it.

On the other hand, all our tests should have a filename "*/tests/test-*", like
they do for autotools.

Rename the meson platform tests.

It's also important because "tools/run-nm-test.sh" relies on the test
name to workaround valgrind warnings.

f754f97900 device: don't reapply IP config on link up for disconnected devices
Only reapply the IP configuration on link up if the IP state is CONF
or DONE. Previously we also reapplied it when the device was
disconnected (IP state NONE) and this could lead to a situation where
an incomplete config was applied; then we intersected the desired
configuration with the external - incomplete - one, causing the
removal of part of desired configuration (for example the default
route).

134ccb4a17 core/lldp: minor cleanup in _lldp_attr_*()
- use nm_g_variant_unref_floating()

- rename _lldp_attr_take_str_ptr() to _lldp_attr_set_str_take().
  The new name has the same "_lldp_attr_set_" prefix as other setters.
  Also, with the previous name it is unclear why it takes a "str-ptr".

- setting the same attribute multiple times, ignores all but the first
  value. Avoid cloning the string in that case, and explicitly choose
  the set or take function.

An OVS bridge and its slaves can continue to work even after NM has

Not all masters type have a platform link and so it's wrong to check

OVS ports don't need the check because they don't call to platform to

511ef27d5e device: check platform link compatibility when setting nm-owned flag
We set nm-owned to indicate whether a software device was created by
NM or it was pre-existing. When checking the existence, we must verify
also whether the link type is compatible with the device, otherwise it
is possible to match unrelated interfaces. For example, when checking
for the existence of an ovs-bridge (which is not compatible with any
platform link) we could match a unrelated platform link with the same
name.

a3e51a74aa policy-routing: take ownership of externally configured rules
IP addresses, routes, TC and QDiscs are all tied to a certain interface.
So when NetworkManager manages an interface, it can be confident that
all related entires should be managed, deleted and modified by NetworkManager.

Routing policy rules are global. For that we have NMPRulesManager which
keeps track of whether NetworkManager owns a rule. This allows multiple
connection profiles to specify the same rule, and NMPRulesManager can
consolidate this information to know whether to add or remove the rule.

NMPRulesManager would also support to explicitly block a rule by
tracking it with negative priority. However that is still unused at
the moment. All that devices do is to add rules (track with positive
priority) and remove them (untrack) once the profile gets deactivated.

As rules are not exclusively owned by NetworkManager, NetworkManager
tries not to interfere with rules that it knows nothing about. That
means in particular, when NetworkManager starts it will "weakly track"
all rules that are present. "weakly track" is mostly interesting for two
cases:

  - when NMPRulesManager had the same rule explicitly tracked (added) by a
    device, then deactivating the device will leave the rule in place.

  - when NMPRulesManager had the same rule explicitly blocked (tracked
    with negative priority), then it would restore the rule when that
    block gets removed (as said, currently nobody actually does this).

Note that when restarting NetworkManager, then the device may stay and
the rules kept. However after restart, NetworkManager no longer knows
that it previously added this route, so it would weakly track it and
never remove them again.

That is a problem. Avoid that, by whenever explicitly tracking a rule we
also make sure to no longer weakly track it. Most likely this rule was
indeed previously managed by NetworkManager. If this was really a rule
added by externally, then the user really should choose distinct
rule priorities to avoid such conflicts altogether.

57048338ee platform/netlink: mark nested netlink attribute with NLA_F_NESTED
Kernel 5.2 is adding stricter checking for netlink messages.
In particular, for certain API it checks now that NLA_F_NESTED flag is
set for nested attributes ([1]).

Note that libnl3 does not ever set this flag, and since our netlink
implementation is copied from there, certain netlink messages are now
rejected as invalid.

On the other hand, libmnl always adds this flag ([2]). So we should do that
as well.

In particular, this affects the WireGuard netlink API causing request
from NetworkManager to be rejected ([3]).

09f37d5bd4 device: fix reapplying changes to connection ID and UUID
4 properties are not really relevant for an already activated connection
or it makes not sense to change them. These are connection.id, connection.uuid,
connection.autoconnect and connection.stable-id.

For convenience, we allow to reapply these. This way, one can take
a different setting (e.g. with a different connection.id or
connection.uuid) and reapply them, but such changes are silently
ignored.

However this was done wrongly. Instead of reverting the change to the new
applied connection, we would change the input connection.

This is bad, for example with

  nmcli connection up uuid cb922f18-e99a-49c6-b200-1678b5070a82
  nmcli connection modify cb922f18-e99a-49c6-b200-1678b5070a82 con-name "bogus"
  nmcli device reapply eth0

the last re-apply would reset the settings-connection's connection ID to
what was before, while accepting the new name on the applied-connection
(while it should have been rejected).

Fixes: bf3b3d444c ('device: avoid changing immutable properties during reapply')

5ca888d693 device: ppp: check that connection has a PPPoE parent
NMDevicePPP only handles connections with the pppoe.parent property
set. match_connection() already checks this when we creating a new
device. We should also perform the same check in
check_connection_compatible().

Setting the IPv6 token triggers a new router solicitation from kernel

aa055239a2 Revert "Coerce connectivity "LIMITED" to "NONE" when device is disconnected"
NMConnectivity can now distinguish between LIMITED and NONE connectivity
and it does so based on whether IP addresses and routes are configured.

Previously, NMConnectivity would not differenciate between limited and
no connectivity, which is why NMDevice added some additional logic on top
to coerce LIMITED to NONE (if the device is not logically connected).

But note that the connectivity state (whether a network is reachable on
an interface) depends on what is configured in kernel and whether the
internet is reachable on that interface. It does not depend on the
logical device state.

On the other hand, whether the device is configured in a manner to have
connectivity depends on the logical state of the device (as NetworkManager
is configuring the device).

So, in many cases, the logical state and the connectivity state agree now,
but for the right reasons.

This reverts commit 4c4dbcb78d.

The platform is used to detect whether to skip the connectivity check right away.
It should be an optional argument, so one could avoid this pre-check.
