The original g_udev_device_get_property_as_int() uses strtol() without
an explicit base (i.e. 0) so that the base is autodetected from the
string whenever possible (e.g. if prefixes with '0x' it is treated as a
hexadecimal string).
But, for ID_USB_INTERFACE_NUM, we explicitly require reading the number
as an hex string, even if we don't have any '0x' prefix.

This is the value which we actually suggest in the manpage for the mmcli
operation, so just use the same one.
Scanning for 3GPP networks may really take a long time, so a specific timeout must be given:
$ mmcli -m 0 --3gpp-scan --timeout=300
Found 4 networks:
21404 - Yoigo (umts, available)
21407 - Movistar (umts, current)
21401 - vodafone ES (umts, forbidden)
21403 - Orange (umts, forbidden)

In place of two slightly different regexes for 2g/3g and 2g/3g/4g modems
we now use only one regex with conditional patterns for both supported
and current Bands detection.
Adding also minor fix in test code

When the device is reset, it needs some time before the newly exposed TTYs are
able to reply to our AT commands. We increase the default timeout of the AT
probing commands in order to cope with that, or we'll end up with TTYs of
'unknown' type that aren't used for anything.
|
|
The implementation uses +UGCNTRD=? to query whether the per-PDP context
statistics are supported by the device, and if they are, +UGCNTRD is used to
query them.
We only process the statistics for the specific CID we're using.
|
|
The parser returns only the results for the CID being specified as input. This
is so that we can just query the statistics of the CID currently in use by the
bearer.
|
|
Reuse the logic and context used to update current modes, as we need the same
steps (check current power state, go into low power, config update, and recover
previous power state).

|
|
Changing current allowed/preferred modes requires the device to be in low-power
mode, so we will make sure we return an error if any power operation is already
ongoing when a new one is requested.
|
|
|
|
|
|
|
|
We handle all known CFUN? response values in the new parser, and report an error
if an unknown value is found.
|
|
|
|
|
|
|
|
AT+URAT=? provides the format expected, but looks like it isn't implemented
differently for the different u-blox devices seen, so we need an additional
level of filtering which currently is applied per device model string.
|
|
|
|
A default implementation to monitor the ongoing connection is provided in the
generic MMBroadbandModem, based on AT+CGACT? to check whether the PDP context
of the connection (identified by the cached cid) is active or not.
This commit also disables the connection monitoring logic in those plugins that
have custom connection methods.
|
|
Instead of setting up a custom timeout source to poll the connection status, use
the generic logic in the base bearer object, and just re-implement the command
used to check the status.
|
|
Split into two different actions the actual COPS? response parsing and the
operator name normalization process.
Also, allow parsing not only the operator string, but also the format, mode
and the optional access technology value.

The dell plugin needs them.

This should avoid poluting the name space and also make module loading
faster.

GE910 is a 2g only modem and when queried for bands it returns
only a 2g set of bands:
--> 'AT#BND=?<CR>'
<-- '<CR><LF>#BND: (0-3)<CR><LF><CR><LF>OK<CR><LF>'
Current regex fails, since it considers the 3g bands block mandatory.
A similar problem happens for current bands.
This patch modifies the regular expressions for properly
supporting GE910 and updates tests.

|
GE910 family supports #PORTCFG layouts different than HE910
family ones.
This patch properly tags GE910 ports according to Telit document
"GE910 Family Ports Arrangements, 1vv0301049"
|
|
This patch adds the udev rules for supporting GE910 (PID 0x22)

<debug> (ttyUSB2): --> 'AT^SYSCFG?<CR>'
<debug> (ttyUSB2): <-- '<CR><LF>^SYSCFG:14,2,400380,1,2<CR><LF><CR><LF>OK<CR><LF>'
<warn> couldn't load current allowed/preferred modes: 'No SYSCFG combination found matching the current one (14,2)'
14,2 means "WCDMA-only; acquire WCDMA then GSM" which is somewhat
non-sensical. The supported modes parsing doesn't generate this
combination because it doesn't really make sense, so current mode
matching failed. Just fix up the non-sensical acquisition order
to 0 (automatic).

Instead of relying on the udev daemon and GUDev to manage the devices reported
by the kernel, we can now run ModemManager relying solely on the kernel events
reported via the new ReportKernelEvent() API. Therefore, the '--no-auto-scan'
option is implicit for the ModemManager daemon when udev is disabled in the
build.
Additionally, a new custom implementation of the kernel device object is
provided, which uses sysfs to load the properties and attributes required in
each kernel device, instead of using a GUdevDevice.
The udev rule files are kept in place, and a simple custom parser is provided
which preloads all rules in memory once and then applies them to the different
kernel objects reported via ReportKernelEvent(), e.g. to set port type hints.
A simple unit test setup is prepared to validate the udev rules during the
`check' Makefile target.
|
|
The mm_base_modem_grab_port() now receives a MMKernelDevice directly from the
plugin, which is then stored in the MMPort corresponding to the port.
This means that we have direct access to e.g. all properties set by udev rules
everywhere, and we don't need additional GUdevClient objects (e.g. like the one
used in the Huawei plugin to detect NDISDUP support during runtime).
For virtual ports (e.g. generated during unit tests), we have a new 'generic'
kernel device object which just provides the values from the kernel device
properties given during its creation.
|
|
Instead of relying constantly on GUdevDevice objects reported by GUdev, we now
use a new generic object (MMKernelDevice) for which we provide an initial GUdev
based backend.

All ports of the same modem reported by the kernel will all be associated with
a common 'uid' (unique id), which uniquely identifies the physical device. This
logic was already in place, what we do now is avoid calling it the 'sysfs
path' of the physical device, because we may not want to use that to identify
a device.
This logic now also enables the possibility of "naming" the modems in a unique
way by setting the "ID_MM_PHYSDEV_UID" property in the "usb_device" that owns
all the ports.
E.g. a custom device has 4 modems in 4 different USB ports. The device path of
each USB device will always be the same, so the naming rules could go like this:
$ vim /usr/lib/udev/rules.d/78-mm-naming.rules
ACTION!="add|change|move", GOTO="mm_naming_rules_end"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.1", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-1"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.2", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-2"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.3", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-3"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.4", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-4"
LABEL="mm_naming_rules_end"
Each of the modems found will have a unique UID retrieved from the previous list
of rules. Then, "mmcli" has also been updated to allow using the UID instead of
the modem DBus path or index, e.g.:
$ sudo mmcli -m USB-MODEM-1
/org/freedesktop/ModemManager1/Modem/0 (device id '988d83252c0598f670c2d69d5f41e077204a92fd')

Commit a66871a2876be2236f634ff6b5e59d20de1ce5df introduced an additional
ATTRS{idVendor} match condition in the same rules matching by interface class,
subclass and protocol. We shouldn't be doing that because we cannot mix parent
attribute matchings from different parents.
