To make the API more consistent, instead of returning an
ActiveConnection object path, return the actual NMActiveConnection
object itself. Suggested by Matthias Clasen.
These days more and more devices are showing up that support a
number of different access technology families in the same hardware,
like Qualcomm Gobi (CDMA and GSM), Pantech UM190 (CDMA and GSM),
Pantech UML290 (CDMA and LTE), LG VL600 (CDMA and LTE), Sierra
320U (GSM and LTE), etc. The previous scheme of having device
classes based on access technology family simply cannot handle
this hardware and attempting to add LTE to both the CDMA and GSM
device classes would result in a bunch of code duplication that
we don't want. There's a better way...
Instead, combine both CDMA and GSM device classes into a generic
"Modem" device class that provides capabilities indicating what
access technology families a modem supports, and what families
it supports immediately without a firmware reload. (Gobi devices
for example require a firmware reload before they can switch
between GSM and CDMA). This provides the necessary flexibility
to the client and allows us to keep the API stable when the
same consolidation change is made in ModemManager.
The current code doesn't yet allow multi-mode operation internally,
but the API is now what we want it to be and won't need to be
changed.
When a DBus error is received, the values of the other parameters
may be undefined, but bindings will assume they're valid and fail.
Capture this case and pass NULL to the callbacks.
Also, allow passing NULL instead of a callback, for bindings that
don't support the argument types.
Clients need to do their own logging using glib or whatever; these
macros while somewhat helpful were not flexible and are not a
substitute for actual logging in the client. g_warning, g_message,
and g_error are more suitable anyway.
DISCONNECTING: the only active network connection is now being disconnected
LOCAL, SITE, GLOBAL: one-stop items for level of connectivity, which
we'll use to show when we think we're actually connected to the internet
or behind a captive portal or something
This policy will allow users to modify their personal connections (ie
maybe VPN connections, etc) distinctly from system-wide connections that
affect more than just their user. It makes sense to be more lenient when
making changes to settings that don't affect other users.
Meaning stays the same, but this will allow us to differentiate
in the future between personal connections (ie, just visible to
one user) and system connections (visible to more than one user).
Simplifies code internally, and makes it easier for clients as well in
some cases where they want to control what ends up in the resulting
hash and what does not.
Add the necessary annotations (the mininum required, that is those
on return values. NULL parameters or container types may require
more), and the Autotools stuff to get a NetworkManager GIR for
libnm-util and a NMClient for libnm-glib.
Moves the system settings permissions checking into the core service's
permissions checking, which at the same time enables 3-way permission
reporting (yes, no, auth) instead of the old yes/no that we had for
system settings permissions before. This allows UI to show a lock
icon or such when the user could authenticate to gain the permission.
It also moves the wifi-create permissions' namespace to the main
namespace (not .settings) since they really should be checked before
starting a shared wifi connection, rather than having anything to do
with the settings service.
Many clients using libnm-glib (often command-line ones like nm-tool
or nmcli) aren't long-lived enough for NM to get their UID from
the bus daemon and validate their permissions via PolicyKit. So
when the NMClient object is created, get the permissions synchronously
(with a very low timeout to prevent unecessary blocking) to ensure
that the client is still on the bus when NM asks for it's credentials.
Avoids a ton of messages like:
NetworkManager[10274]: <warn> error requesting auth for org.freedesktop.NetworkManager.enable-disable-wwan: (6) Remote Exception invoking org.freedesktop.PolicyKit1.Authority.CheckAuthorization() on /org/freedesktop/PolicyKit1/Authority at name org.freedesktop.PolicyKit1: org.freedesktop.DBus.Error.NameHasNoOwner: Remote Exception invoking org.freedesktop.DBus.GetConnectionUnixUser() on / at name org.freedesktop.DBus: org.freedesktop.DBus.Error.NameHasNoOwner: Could not get UID of name ':1.95': no such name
Since forever we've used sleep/wake as the way to implement
Networking Enabled. When the state file was introduced to make the
networking and wifi states persistent, we ran into a bug where
a failed suspend (like if the machine ran out of power while
suspended) would result in networking being disabled on reboot
since suspend/resume used the same knob as enable/disable.
This patch adds a distinct call for enable/disable networking
which changes the state file, while sleep/wake no longer change
the state file.
