udev doesn't know about the device yet when NM creates it internally.
NetworkManager[9275]: <info> (team0): carrier is OFF
NetworkManager[9275]: <info> (team0): new Team device (driver: 'team' ifindex: 16)
(NetworkManager:9275): GUdev-CRITICAL **: g_udev_device_get_property: assertion 'G_UDEV_IS_DEVICE (device)' failed
NetworkManager[9275]: <info> (team0): exported as /org/freedesktop/NetworkManager/Devices/5
No idea why was it there in the first place.
This also fixes a bug that the rules file was conditionally included in dist
depending on presence of udev dir at configure time.
There are some out-of-tree drivers that create devices masquerading as
ethernets which are supposed to use their own management tools. Avoid touching
them.
The rules should be run after 80-net-setup-link.rules, so that the
ID_NET_DRIVER is set.
Some out of tree drivers add Ethernet devices that are supposed to be managed
by other their tooling, e.g. VirtualBox or VMWare.
Rather than hardcoding their drivers (at least VirtualBox doesn't even set a
"driver" property in sysfs) or hardcoding a logic that identifies such devices
let's just add a possibility to blacklist them in udev. This makes it possible
for whoever who ships such a driver to ship rules that prevent NetworkManager
from managing the device itself.
Furthermore it makes it possible for the user with special needs leverage the
flexibility of udev rules to override the defaults. In the end the user can
decide to let NetworkManager manage default-unmanaged interfaces such as VEth
or turn on default-unmanaged for devices on a particular bus.
An udev rule for VirtualBox would look like this:
SUBSYSTEM=="net", ENV{INTERFACE}=="vboxnet[0-9]*", ENV{NM_UNMANAGED}="1"
There's no udev running in containers, it only starts if /sys is writable. If a
hardware device is added to the container's namespace NM would not announce it.
This also removes the software link special case -- the software links will now
wait for udev initialization (in case udev is there) as well. There's no reason
to treat them differently anymore. This makes it possible to use udev properties
of the software links.

The sort order of nm_setting_enumerate_values() affects the
order in which keyfile writer serializes the properties.
Have a defined, stable sort order by sorting the properties
by name (with prefering id,uuid,type for NMSettingConnection).
nm_connection_for_each_setting_value() is used by keyfile writer to iterate
over the settings and write the keyfile entires. The order there is important
as g_key_file_to_data() prints the groups in the order they were created.
To have a stable order and to have the [connection] entry first, sort the
settings.
libnm-core treated the UNKNOWN WEP key type as KEY. Relax that
and try to guess the correct type based on the key.
This is for example important if you have a valid connection with
wep-key-type=0 (unknown)
If you request passwords for such a connection, the user cannot
enter them in password format -- but there is no UI indication
that the password must be KEY.
We must never fail verification of a connection based on a password
because the password is re-requested during activation.
Otherwise, if the user enters an invalid password for a (previously)
valid connection, the connection becomes invalid. NetworkManager does
not expect or handle that requesting password can make a connection
invalid.
Invalid passwords should be treated as wrong passwords. Only a UI
(such as nm-connection-editor or nmcli) should validate passwords
against a certain scheme.
Note that there is need_secrets() which on the contrary must check for
valid passwords.
Error scenario:
Connect to a WEP Wi-Fi, via `nmcli device wifi connect SSID`. The
generated connection has wep-key-type=0 (UNKNOWN) and wep-key-flags=0.
When trying to connect, NM will ask for secrets and set the wep-key0
field. After that, verification can fail (e.g. if the password is longer
then 64 chars).
Some refactoring of the main() functions for NetworkManager and
nm-iface-helper. Most notably, start the D-Bus service earlier so
that NetworkManager starts faster.
https://bugzilla.gnome.org/show_bug.cgi?id=746254
systemd considers the startup time of NetworkManager until the D-Bus
service is claimed. By doing that earlier, this time is significantly
reduced.
This has the advantage, that services that are ordered to start
after NetworkManager can start earlier. Most notably, 'network.target'
orders itself After=NetworkManager.service and many services are ordered
After=network.target.

Create the rundir earlier and before setting up nm-logging.
nm_main_utils_ensure_rundir() errors out with fprintf(stderr)
and does not need nm-logging.
And rename the function to nm_main_utils_ensure_not_running_pidfile()
to match the other _ensure_ functions that exit(1).
Also no longer pass @name to nm_main_utils_ensure_not_running_pidfile()
and use g_get_prgname() instead.
nm_main_utils_ensure_not_running_pidfile() checks that the running
process has the same program name, so this changes behavior if the
user renamed the binary. Before, we would check whether the running
process is named 'NetworkManager' ('nm-iface-helper'). Now we check
whether the process has the same name as the current process.
This means, that if you rename the binary to 'NetworkManager2' we
would now only detect a conflicting 'NetworkManager2'. Before we would
only detect conflicting 'NetworkManager' binaries.
Move call to nm_main_utils_early_setup() to a separate function.
Also move the @options array away from the main function, saving
a few bytes on the stack.
Now only do_early_setup() modifies the @global_opt structure.
Move the variables to a static struct so that we can factor
out some of the initialization code.
Also it's nice to have all options placed together in one struct so
that is is obvious which static variables are part of the command line
options, and which have other use.
