Modem device inhibition is really a manager action for which we
provide the full modem device 'uid'.
This new operation allows to perform device inhibition using the modem
object as reference, which is more handy than first looking at the
device 'uid' and then running the manager action.
$ sudo mmcli -m 0 --inhibit
successfully inhibited device with uid '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12.2'
type Ctrl+C to abort this program and remove the inhibition
^C cancelling the operation...
successfully uninhibited device with uid '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12.2'
This new method allows users of the ModemManager API to take full
control of a given device.
Unlike other operations in the API, the inhibition is maintained as
long as the caller exists in the bus, or until the same caller
uninhibits the device.

Since the Firmware interface now contains more actions and properties
apart from List() and Select(), these two actions are now optional.
Not all modems implementing the Firmware interface must implement
these two methods.
The DW5821e uses the AT^FASTBOOT command to reset the module in
fastboot mode, ready to download new firmware.
Note: we cannot use AT^FASTBOOT=? to query for support, as that
command also triggers the reset :/
We no longer "check for support" of this interface, it will always be
available for all modem objects.
The only implementation that used this interface was the QMI one, and
only for a very small subset of devices (those supporting the "QMI DMS
List Stored Images" operation). The logic was changed so that the list
of stored images wasn't preloaded during the support check; it will
now instead be preloaded during the first call to List().
Here the string is already decided to be NULL and passing
a null pointer to %s will not work

commit 397faef3c5 ("mm-common-helpers: add mm_autoptr helpers for
GRegex and GMatchInfo") introduces mm_autoptr(), which implements
g_autoptr() that isn't available before glib 2.44. This patch fixes the
code to consistently uses mm_autoptr().
The standard says a RING or CRING should be emitted whenever the
network sends an incoming call notification, which is nation-specific:
"Interpretation of indications from the network to determine what
constitutes a "ring" is defined by national regulations. This
result code should be repeated each time the network repeats the
incoming call indication." -- ITU-T Rec. V.250, p. 42
On the giffgaff (O2) network in the UK, a SIMCom SIM7100E modem emits
RING indicators every six seconds. The current timeout is only five
seconds resulting in a stream of timed-out ModemManager call objects
whenever there is an incoming call. To fix this, we increase the
timeout to ten seconds.
The handler assumes the regex sub-expressions each have the same index
so they need to be within the same set of parentheses rather than each
individually parenthesised. Without this fix, call state changes are
missed.
So that the returned error is much more descriptive.
E.g. instead of this:
$ sudo mmcli -m 0 -e
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method Enable is not implemented on interface org.freedesktop.ModemManager1.Modem'
We'll get this:
$ sudo mmcli -m 0 -e
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.WrongState: modem in failed state'
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/issues/96
When the MMIfaceModem initialization returns with the SIM_NOT_INSERTED
error, the base logic is already updating the modem failed reason to
SIM_MISSING. There is no need to do that explicitly for the case where
SIM hot swap is supported.
For subclasses of MMBroadbandModemMbim, also apply the same property
defaults. E.g. we want to avoid peridic signal quality polling and we
also want to report that SIM hot swap is supported.
Even if some fields wouldn't apply to some modem, we're always
including all in the output so that clients can assume the fields are
always given.
Fix adding the 3GPP EPS related fields unconditionally.
This property contains the DBus path of a Bearer object of type
MM_BEARER_TYPE_DEFAULT_ATTACH, which is automatically exposed by the
modem when registered in the LTE network.
Unlike standard bearer objects created by the user, this bearer won't
allow any connection/disconnection request, as its status is bound to
the LTE registration exclusively.
The bearer settings exposed by the object include the APN details that
have been used during the initial packet network attach, which may be
defined by modem settings (e.g. if previously configured in the
firmware which APN to use for the given SIM card operator) or by the
network itself (e.g. if none configured, or if a network override is
required as when roaming).
The bearer object will be created as soon as the LTE attach status
details are known, and only while the modem is enabled. The
implementation allows modems to update the LTE attach status details
during runtime, so the bearer object with the settings may be
recreated during runtime as well.
Until now we have only allowed to use and setup 'default bearers' (in
4G) or 'primary contexts' (in 2G/3G).
We can define a couple of additional bearer types, though:
* The 'dedicated bearers' (in 4G) or 'secondary contexts' (in 2G/3G),
which are associated to a specific default/primary one, but which
provide specific QoS settings configured via traffic flow templates.
* The 'initial default EPS bearer', which is a special case of default
bearer in LTE, which is automatically created and connected when the
modem is registered in the LTE network.
This commit introduces a new 'MMBearerType' enumeration that will be
associated to each bearer through a 'BearerType' property in the
org.freedesktop.ModemManager1.Bearer interface, showing what kind of
bearer/context this is.
By default, right now, all bearer objects created are 'default'
bearers.
We were re-using the GDBusObjectManagerClientFlags set in the
MMManager object as GDBusProxyFlags for the Manager1 interface proxy
object, and that was completely broken.
Instead of setting "DO_NOT_AUTO_START" in the proxy, we were actually
setting "DO_NOT_LOAD_PROPERTIES"...
This patch fixes the following compiler warning:
mmcli-output.c:783:19: error: implicitly declaring library function 'strlen' with type 'unsigned long (const char *)' [-Werror,-Wimplicit-function-declaration]
aux = strlen (section_infos[field_infos[item_l->field].section].name);
