On every start of NetworkManager I'd see a warning message:
modem-broadband[cdc-wdm0]: failed to retrieve SIM object: No SIM object available
Apparently, to warn about this is too alarming.
Commit f85941ee91 ("device: don't try to generate ipv6ll address for
disconnected devices") disabled the generation of IPv6 link-local
addresses for disconnected devices to fix a crash. However that broke
the following:
$ ip a f dev eth0
$ systemctl start NetworkManager
$ nmcli d
DEVICE TYPE STATE CONNECTION
eth0 ethernet disconnected eth0
$ ip a a dev eth0 2001::42/64
$ ip a show eth0
4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 52:52:00:61:32:81 brd ff:ff:ff:ff:ff:ff
inet6 2001::42/64 scope global
valid_lft forever preferred_lft forever
(no link-local address)
Instead, enable the generation of a link-local address even if the
device is disconnected and fix nm_device_get_ip_iface_identifier() to
not require a connection if @ignore_token is set.

If the read of teamd configuration failed (possibly due to a timeout),
fail the connection immediately where possible instead of letting it
continue and risk to block again at the next read.

When a device is activated any existing teamd instance is killed. But
since commit 28274495d6 ("device/team: always try to connect to
teamd in update_connection()") the disappearing of the D-Bus name
owner always triggers an automatic restart of the instance in
teamd_dbus_vanished() if the name was previously owned. This new
instance conflicts with the instance we're about to start.
Instead, restore the previous behavior of restarting teamd only if
there is an activation in progress and use @tdc as a flag. This also
means that update_connection() should not modify the value of @tdc.
Fixes: 28274495d6
A infinite activation loop can arise when the master repeatedly fails
activating: slave's _internal_activate_device() calls
ensure_master_active_connection() to activate the master connection
and during master activation activate_slave_connections() resets the
retry counter of slaves.
The autoconnect retry counter of a slave should only be reset for
explicit master activations, not for auto-activations.
https://bugzilla.redhat.com/show_bug.cgi?id=1270814
When the master connection deactivates, we also fail slave
connections; but if the master deactivation happens just before a
slave reaches the PREPARE state, we failed to notice it and keep
the slave stuck without chance of progressing. Fix this.
Since nm_device_slave_notify_release() is called from outside the
activation chain of the slave device (it gets called from the master
device) there might be pending activation sources scheduled, clear
them before queueing a state change.
Previously we used defines for bond option names and used string
literals for their attribute names in sysfs. But they are the same by
definition so let's use defines also for attributes.
Even if the 'ad_actor_system' option is only valid for the 802.3ad
mode, the sysfs file is always present and has a default value of
''. But in 802.3ad mode the default value is
'00:00:00:00:00:00'. Return the correct value in
nm_setting_bond_get_option_default().
Furthermore, writing a empty string to the file will generate an
error, don't do it.
We print an error when the write of a bond options fails as this is
considered an effect of a wrong configuration (or a bug in the checks
done by NM) that the user should notice. But not all options are
supported in all bonding modes and so we ignore some unsupported
options for the current mode to avoid populating logs with useless
errors.
Improve the code there by using a more generic approach and
synchronize the mode/option compatibility table with kernel (file
drivers/net/bonding/bond_options.c).

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.

A warning is too verbose. This is not an unusual condition, it's just that
a new activation supersedes an other one.

NM_CONTROLLED=no is an explicit user configuration. There is no point in
issuing a warning that the user doesn't want to manage a device.

Also, don't truncate the device spec, instead show the full
device spec, it may contains a MAC address or a s390 subchannel.
No longer typedef NMDeviceEthernet to NMDevice. We don't do that
for most other classes, and I think it is not a good pattern
(yes, the casts are cumbersome, but what can you do).
Also, embed a pointer to the private data in NMDeviceEthernet
for fast lookup and ease of debugging.
We should overwrite the constructed() method instead of hooking the
GObject creation via constructed(). That is much cleaner as at that
point the GObject is fully initialized.
Also, this avoids a pointless warning when trying to get the not yet
initialized GUdevDevice:

Trying to set a property on a device that does not exist is not something
necessarily wrong. Don't print error/warning messages.

The function name is no longer visible in the default
logging output. It is anyway only used together with
journal logging to set "CODE_FUNC".
Drop it. It allows to remove the strings from the binary,
which decreases the object size of a default build of NetworkManager
from 2437400 to 2412824 bytes (-24k, -1%).
