Previously, these drivers would check /sys/devices/virtual/misc/tun to
see if TUN is supported, and bail out otherwise. However, the tun module
can sometimes be autoloaded by opening the /dev/net/tun file. In this
case the /dev file already exists, but the /sys file only gets created
after the modul is loaded.
Additionally, the ppp code does not use the /sys file, but only the
/dev file, so checking for the existence of the latter seems a better
indicator of expected success.
... when a USSD notification is received. Some networks
send 0 (no further user action required) after the response
timeout expires. That should result in the user input form
getting removed from the ME screen.
When registering to an operator ofono uses the old RAT.
In the case the modem is not connected to any network, this would use
QMI_NAS_NETWORK_RAT_NONE which results in the error OP_DEVICE_UNSUPPORTED.
Use QMI_NAS_NETWORK_RAT_NO_CHANGE instead to not define any preference.
Fix a warning when only voicecall.h is included:

If the ME storage is full, the modem will reject new messages
with a SMPP RP-Error 'Protocol error, unspecific'.
It seems the qmimodem is first checking the ME storage for
free space, then deliver the SMS via QMI and not saving it
to the ME anyway.
Using QMI_WMS_STORAGE_TYPE_NONE it doesn't check for free space.
Tested-on: Quectel EC20
add documentation about interface cinterion.HardwareMonitor.
This interface exposes a single method to access temperature and supply
voltage of the modem.
Gemalto modems have hardware related commands, allowing to monitor voltage
and temperature. These parameters will be accessible on DBus interface:
org.ofono.HardwareMonitor.
- Create the DBus method table with one entry: GetStatistics. This method
would return temperature and voltage values.
- Create a dedicated structure to handle the DBus methods.
- Create enable/disable functions to handle DBus interface registration.
When qmi_device_shutdown is used and the callback provided utilizes
qmi_device_unref, an access into already freed memory is triggered.
Sequence of events is:
1. timeout fires
2. glib calls timeout callback (e.g. shutdown_callback) which in turn
calls shutdown_func (gobi shutdown_cb) which in turn calls
qmi_device_unref()
3. qmi_device_unref calls g_source_remove, which doesn't call the
destroy callback (it is blocked)
4. qmi_device_unref then frees the memory used by device
5. glib then calls the source destroy callback (e.g. shutdown_destroy)
which results in just freed memory being used.
glib appears to always call the destroy callback, even if the source has
been removed previously. So to work around the issue, delay the actual
g_free until the destroy callback is invoked.
There are two problems with using pri_set_apn. The first issue is that
this function was built to be used by the set_property handler and
assumes the presence of a pending DBusMessage.
The second issue is that it touches the settings store.
In the case of auto-activated contexts no pending message exists. Also,
we should not be touching the settings store as the APN might
potentially be a value that has not been provisioned. Or in some cases
bogus.
This adds Acquire method which can be used by agents that require
pulling the fd directly instead of waiting a NewConnection.
Note: sounds servers like PulseAudio do auto suspend streams when idle
for a certain amount of time and once anything happens it will resume
the stream, though this all happens in the so called IO thread in a
blocking fashion making it impossible to receive the fd via NewConnetion
causing the stream to fail to resume. There are other forms to work
around but this seems to be most convenient as we do want the auto
suspend feature to work properly but letting the stream to fail to
resume may create unexpected artifacts while the NewConnection is
handled in main thread.
Apparently, an empty APN in an ofono context means that that the context
cannot be activated. connman definitely interprets it this way.
This patch sets a default name of "automatic" for the default bearer if
no other LTE APN is supplied (which is currently the case as the LTE
atom is not in place yet). Without this, connman happily ignores the
context, even though it has been activated by ofono.
When the modem attaches to an LTE network, a default bearer is
automatically negotiated using the "defalt profile" settings. The
QMI modem, however, does not given any explicit indication that
the bearer exists; instead, we must assume its existence based on
the network registration state.
This patch extends the GPRS atom to signal the presence of a
default bearer when it detects network connectivity on an LTE
network.
Apparently it's not legal to create a QMI service multiple times for
a device. I've been testing with a Quectel EC21 and here it works fine
to do so, but the general case would require "shared" services across
atoms.
This patch switches the users of the NAS and WDS services over to using
a "shared" service instead of each instatiating their own instance.
There are three principal ways for a context to become disconnected:
i) deactivate_primary() is called
ii) the network registration is lost and the context is cleaned up
via _detach_shutdown() (via release_all_contexts())
iii) the network decides to disconnect the context
We need to watch the packet status in order to detect case iii). For
case i) and ii), stop_net will be called, the pkt_handle will be
cleared, and subsequent packet status notifications be ignored.
This patch makes it so that the packet status "disconnected" event
is only propagated when the pkt_handle has not been cleared, indicating
an unrequested disconnection.
This should fix a race reported by Christophe Ronco whereby the packet
status disconnect notification is called between activate_primary
(start_net) and it's callback (start_net_cb).
This adds handling for ServicesResolved signal which tells when BlueZ
is done resolving the device services so the code will no longer ignore
devices that got its services resolved after Paired signal.
In case the UUIDs are not updated, as they are still being resolved, when
Paired property changes a modem will never be registered.
In order to fix this problem allow modems to be registered directly
during NewConnection.
SMS reception is not working for Gemalto modems because of +CMT parsing.
PDU length is the first argument of +CMT URCs in Gemalto modems.
Add a switch case on vendor info to handle Gemalto case.
Also handle acknowledgment, +CNMA takes only one parameter.
CMT parsing is moved from at_parse_cmt() to at_cmt_notify(). This
function is modified to match the style of at_cmgr_notify() and it
includes a switch case for CINTERION modems.
