c3b6a44ef6 core,libnm: don't touch device TC configuration by default
NetworkManager supports a very limited set of qdiscs. If users want to
configure a unsupported qdisc, they need to do it outside of
NetworkManager using tc.

The problem is that NM also removes all qdiscs and filters during
activation if the connection doesn't contain a TC setting. Therefore,
setting TC configuration outside of NM is hard because users need to
do it *after* the connection is up (for example through a dispatcher
script).

Let NM consider the presence (or absence) of a TC setting in the
connection to determine whether NM should configure (or not) qdiscs
and filters on the interface. We already do something similar for
SR-IOV configuration.

Since new connections don't have the TC setting, the new behavior
(ignore existing configuration) will be the default. The impact of
this change in different scenarios is:

 - the user previously configured TC settings via NM. This continues
   to work as before;

 - the user didn't set any qdiscs or filters in the connection, and
   expected NM to clear them from the interface during activation.
   Here there is a change in behavior, but it seems unlikely that
   anybody relied on the old one;

 - the user didn't care about qdiscs and filters; NM removed all
   qdiscs upon activation, and so the default qdisc from kernel was
   used. After this change, NM will not touch qdiscs and the default
   qdisc will be used, as before;

 - the user set a different qdisc via tc and NM cleared it during
   activation. Now this will work as expected.

So, the new default behavior seems better than the previous one.

b5f64ff493 move tc parsing out of nm-device.c
The logic to create platform qdiscs from a setting does not belong to
NMDevice. Move it to NetworkManagerUtils.h.

wifi: fix evaluating the scanning state for wpa-supplicant
wpa_supplicant has a property "scanning" and a "state=scanning".
Previously, NetworkManager considered both parts to indicate whether
supplicant is currently scanning (if either the property or the state
indicated scanning, it took that as indication for scanning).

If NetworkManager thinks that supplicant is scanning, it suppresses
explicit "Scan" requests. That alone is not severe, because the "Scan"
request is only to trigger a scan in supplicant (which supplicant
possibly is already doing in state "scanning").

However, what is severe is that NetworkManager will also block autoconnect
while supplicant is scanning. That is because NetworkManager wants to get
a complete scan result before deciding which network to connect to.

It seems that wpa_supplicant can get into "state=scanning" and stay
there indefinitely. This prevents NetworkManager from autoactivating
a profile.

Fix that, to only honor the "scanning" property.

device/wifi: don't reset the SSID of a NMWifiAP to unknown
For hidden networks, we usually don't have an SSID. We try to match
and fill the SSID based on the profiles that we have:

  <debug> [1603798852.9918] device[6b383dca267b6878] (wlp2s0): matched hidden AP AA:BB:CC:DD:EE:FF => "SSID"

However, we should not clear that value again on the next update:

  <trace> [1603798856.5724] sup-iface[66c1a0883a262394,0,wlp2s0]: BSS /fi/w1/wpa_supplicant1/Interfaces/0/BSSs/3 updated

Once we have a SSID, we can only update it to a better value,
but not clear it.

Instead, the start and end times must match exact (in their duration),

f160e72b0d device: fix autoactivating virtual devices after a failure
When a virtual device fails, its state goes to FAIL and then
DISCONNECTED. In DISCONNECTED we call schedule_activate_check() to
schedule an auto-activation if needed. We also schudule the deletion
of the link through delete_on_deactivate_check_and_schedule(). The
auto-activation attempt fails because the link deletion unmanages the
device; as a result, the device doesn't try to auto-activate again.

To fix this:

 - don't allow the device to auto-activate if the device deletion is
   pending;

 - check again if the device can be auto-activated after its deletion.

modem: suppress deprecated warning from libmm for MM_MODEM_CAPABILITY_LTE_ADVANCED
On Ubuntu 20.10, we build against ModemManager 1.14.0 and get a compiler warning:

  ../src/devices/wwan/nm-modem-broadband.c: In function 'try_create_connect_properties':
  ../src/devices/wwan/nm-modem-broadband.c:492:2: error: 'MMModemCapabilityDeprecated' is deprecated [-Werror=deprecated-declarations]
    492 |  if (MODEM_CAPS_3GPP (ctx->caps)) {
        |  ^~

Suppress it.

An alternative would be to drop the flag entirely. It seems the flag
was never used (and never will be used). But if that's true, there is
little harm done checking it. If it's not true, we better keep checking
for older versions.

wifi: avoid crash due to incomplete Wi-Fi API info
In this case, GetAll failed with "Timeout was reached". We still
create a dummy BSS info, because we kept track of the object to
start with. That way, we don't simply want to ignore the failure,
because NMDeviceWifi might track this NMWifiAP already, and we may
need an update (even if we failed to fetch the requested information).

However, that later leads to a crash, because NMDeviceWifi expect the BSSID
present then.

Avoid that, by don't processing such APs.

18c76745f6 dhcp6: don't require a hardware address
The systemd DHCPv6 client requires a hardware address only to
determine the IAID; NM always overrides the IAID with its own and
therefore the hwaddr is not used.

Removing such requirement allows DHCPv6 to run over PPP, which is
useful with DHCPv6-PD to get a prefix from the ISP.

To test this, I set up a server with pppoe-server, radvd and the Wide
DHCPv6 server providing an address and a prefix. On the client, NM was
able to obtain a prefix using both dhcp=dhclient and dhcp=systemd.

Note that if there is no hardware address and you specify
ipv6.dhcp-duid=ll or ipv6.dhcp-iaid=mac, a warning will be emitted and
NM will use a random DUID/IAID.

dcb48bc9d9 device: downgrade warning about IPv6 MTU if IPv6 is disabled
If IPv6 is disabled, changing the IPv6 MTU fails and NM complains with
a warning. Since this error is expected and doesn't do any harm,
downgrade the logging level to DEBUG.

Since IPv6 kernel support can be built as a module, we have to check
the existence of /proc/sys/net/ipv6 every time. Instead of checking it
and then setting the MTU (adding one /proc access for everyone), just try
to set the MTU; in case of failure, determine the reason for the error.

0139995590 ovs: also set cloned MAC address via netlink
We already set the MAC of OVS interfaces in the ovsdb. Unfortunately,
vswitchd doesn't create the interface with the given MAC from the
beginning, but first creates it with a random MAC and then changes it.

This causes a race condition: as soon as NM sees the new link, it
starts IP configuration on it and (possibly later) vswitchd will
change the MAC.

To avoid this, also set the desired MAC via netlink before starting IP
configuration.

127294babc ovs: set MAC address on the bridge for local interfaces
When a user creates a ovs-interface with the same name of the parent
ovs-bridge, openvswitch considers the interface as the "local
interface" [1] and assigns the MAC address of the bridge to the
interface [2].

This is confusing for users, as the cloned MAC property is ignored in
some cases, depending on the ovs-interface name.

Instead, detect when the interface is local and set the MAC from the
ovs-interface connection in the bridge table.

ef755588ad device: restart DHCP only for devices that are active or activating
do_sleep_wake() tries to restart DHCP for all devices, even ones that
are disconnecting. When a device is disconnecting, it still has a DHCP
client instance but we shouldn't restart it because it makes no sense;
and especially, the device could be already removed.

8db1529083 core: fix check on master active-connection failure
The previous check was never satisfied, as the device is assigned to
the active-connection and realized early. Instead, check the
master_ready flag, which tells if the master is ready and, therefore,
if the slave has already been added to the master.

Before this commit, in some cases a device didn't detect that the
master failed and kept waiting forever.

ecb134ac34 policy: block connection from autoconnect in case of failed dependency
A connection that fails due to dependency-failed is not able to
reconnect until the master connection activates again; when this
happens, the master clears the blocked reason for all its slaves in
activate_slave_connections() and tries to reconnect them. For this to
work, the slave should be marked as blocked when it fails with
dependency-failed.

7913275b02 manager: fix race condition when resuming from sleep
If the device state change (to disconnected or unmanaged) triggered by
a sleep event happens after the wake, the devices becomes wrongly
unmanaged and it's necessary to manually manage it again, or restart
NM.

During the wake event we should disconnect the device_sleep_cb()
callback for all devices because we don't want to react to state
changes anymore; in particular we don't need to detect when the device
becomes disconnected to unmanage it.
