wifi_utils_is_wifi() only has one caller, so it's very clear
what the passed in @sysfs_path contains. Instead of accepting
a redundant argument, compute the sysfs path internally based
on @iface alone.
The main purpose of audit logging is to understand who did what to the
system configuration, so it is useful to log also the list of changed
properties when a connection is updated:
op="connection-update"
uuid="2f3e48fc-5f47-41d9-9278-d2871378df43"
name="pppoe1"
args="pppoe.username,pppoe.password" <========
pid=9523
uid=1001
result="success"
Otherwise NetworkManager can be too fast calling a method:

Therefore we unrealize the NMDevice instance but the backing resources
stay around, preventing us from ever realizing the device again.

In commit ca000cffbb, we changed to
accept a plugin library name without path. One reason for that
is to keep architecture dependent parts out of the .name file
and possibly support multilib.
However, the shared libraries of VPN plugins are not installed in
a global library search path, but for example into
"/usr/lib64/NetworkManager/libnm-vpn-plugin-openvpn.so".
In that case, specifying "plugin=libnm-vpn-plugin-openvpn.so"
would not be enough to find plugin.
Instead, when configuring a plugin name without path, assume
it is in NMPLUGINDIR directory. Modify nm_vpn_editor_plugin_load_from_file()
to allow path-less plugin-names. Previously such names would be rejected
as not being absolute. This API allows to do file verification
before loading the plugin, but it now supports prepending NMPLUGINDIR
to the plugin name. Basically, this function mangles the plugin_name
argument and checks that such a file exists.
The recently added nm_vpn_editor_plugin_load() continues to behave
as before: it does no checks whatsoever and passes the name directly
to dlopen(). That way, it uses system search paths like LD_LIBRARY_PATH
and performs no checks on the file.
Fixes: ca000cffbb
Contrary to nm_vpn_editor_plugin_load_from_file(), this allows
to specify a library name without path. In this case, g_module_open()
(dlopen()) will search for a library in various system directories.
Since commit 3dfbbb227e, we enforce that
the plugin path in the .name file is absolute and we perform several
checks on the file before loading it (ownership, etc).
Relax that, to also allow libray names without path component.
In that case, g_module_open()/dlopen() will search for a library
in various search paths. This allows, to omit absolute paths
in the .name file. The latter is problematic, because by default
we install the .name file in the architecture independent location
/usr/lib/NetworkManager. As such, it should not contain paths
to architecture dependent libraries. With this change, a .name
file can contain only the library name and it will be loaded
using the usual mechanism.
However, specifying absolute paths is still possible and works
same as before, including checking file permissions.
As such, distributions probably should package the VPN plugins
to have no path in the .name file. On the other hand, a user
compiling from source probably wants to specify an absolute
path. The reason is, that the user probably doesn't build the
plugin for multiple achitectures and that way, he can install
the plugin in a separate (private) prefix.
Instead of looking into the keyfile, lookup the "supports-multiple-connections" setting
in the "keys" hash. This has some behavioral difference:
- g_key_file_get_boolean() first does g_key_file_get_value(), and then
converts the string using the private g_key_file_parse_value_as_boolean()
function -- which is case-sensitive, accepts "true|false|0|1" and
considers only the text until the first whitespace.
- now, we put g_key_file_get_string() into the cache "keys" and
parse it with _nm_utils_ascii_str_to_bool(). The latter is
case insensitive, allows also "yes|no|on|off", strips whitespaces.
However, the difference is subtle and shouldn't matter.
The point of this change is to free "keyfile" after construction.
The device creation can be attempted if the name can be determined. It
alone is doesn't mean that there's a parent device -- the name could
just have been hardcoded in the connection.

update_connection() may be called during startup when the bus watch
hasn't notified yet the presence (or absence) of the teamd service on
the bus. Try to obtain a connection to the service in order to
retrieve the current configuration.
If the connection specifies an interface name, it should never attach to
a device of a different name even if the factory thinks the connection
is compatible with the device.
This fixes an issue that caused the inifniband connections to attach to
different devices or partitions.
Now that we support multiple VPNs active at the same time, the DNS
manager must be able to keep a list of all the VPN configurations and
give them a higher priority than other configurations.
Before this commit all the VPN configuration except one were
considered as normal configurations.

When we want to preserve the default-route on cleanup, we must first
set it to assumed, before clearing it. Otherwise, NMDefaultRouteManager's
update() will delete the default route.
This is the oposite of the deconfigure case, where we first set it to
!has && !assumed, to force the route-manager to delete the route.
Add a function _update_default_route() to set the default_route
flags and call update() in one step.
Also, if there are no changes, skip the call to NMDefaultRouteManager's
update().
