There is no DBus API for SetAllowedModes, but only for SetCurrentModes.

If QMI support was not compiled in, then every net port that wasn't
a QMI port would be force-ignored unless it had the qmi_wwan driver.
Instead, we want to ignore ports with only the qmi_wwan driver.

There are modems out there (e.g. SIM7600E) where we connect a given
CID >1 but once connected, only CID=1 is reported as connected, and
not the one we explicitly attempted to connect. In this situation the
modem is connected successfully, and we're properly ignoring the
disconnection report detected from CGACT? responses, but we're
probably better logging this situation only in debug level, not as
info, because this check is done periodically every 5s...

And added support for several new things, including:
* Setting "any" band now attempts to set all supported bands.
* Added new 2G band value '5' (egsm+dcs+pcs+g850).
* Setup support for two different 3G band combinations, a default one
plus an alternate one applicable to the LM940/960 models only. The
alternate combination is selected via udev tags.
During the refactor, the following Telit-specific helpers were also
removed and exchanged with more generic counterparts.
* mm_telit_bands_contains() -> mm_common_bands_garray_lookup()
* mm_telit_get_band_flags_from_string() -> mm_parse_uint_list()

Very much like the MBIM implementation, we will now retry the lock
check if we get a 'SIM not inserted' error reported, because it may
very well be that the device has just been powered up and the SIM is
not fully detected yet.
|
|
If the modem interface reports that this is the last attempt to load
the lock status and the modem is still reporting no sim, then, we'll
report a hard error right away. Otherwise, we'll let the generic logic
retry the operation, instead of doing it ourselves.
|
|
The load_unlock_required() step will be automatically retried by the
generic interface logic unless some specific errors happen (e.g. it
won't be retried if a SIM missing error is received).
This patch allows telling the implementation of the method whether
this time being run is the last one before reporting a hard error or
not.
|
|
Rework how the broadband bearer runs CGDCONT? and CGDCONT=? and setup
a helper method to perform the CID selection logic.
Also, implement unit tests for the CID selection logic.
|
|
When looking for the first unused CID, we should also consider those
contexts defined with a different PDP type, not just the ones with the
same PDP type.
|
|
There are two places where we look for unused CIDs:
* First, while processing the list of existing contexts returned by
CGDCONT?, we look for gaps in the used CIDs. E.g. if the first
context has CID=1 and the next one has CID=3, we can definitely use
the unused CID=2.
* Then, while processing the response of CGDCONT=?, we try to see
whether there is any empty CID available after the last existing
one found. E.g. if the last existing context has CID=3 and the
format tells us that the max allowed CID is 16, we can definitely
use the unused CID=4.
In both these cases, we should prefer using such an unused CID found
to overwriting other CIDs that are already defined.
This logic will now overwrite existing CIDs only if there are no
unused CIDs, and the preference to overwrite is as follows:
* If there is any existing context defined without an explicit APN,
overwrite it.
* Otherwise, overwrite the last existing CID found.
* And in the worst case, when no list of contexts was loaded
properly (e.g. some Android phones don't allow querying), fallback
to overwriting CID=1.
|

When a modem reported back non-sequential CIDs, MM was using the next
larger CID number after the last CID found. In cases where the last CID
found was the highest numbered CID allowed and is not a modifiable CID,
MM would give up and fail to establish a data connection.
The above issue occurs on u-blox TOBY-R200 modems as of firmware 30.33
A02.02. In this firmware version there are two default CIDs programmed
into the modem, one at CID 1 and another at CID 31. The CID at 31 is
the highest CID number that can be used and cannot be modified.
This change makes it so while parsing CIDs for a match, if a jump in CID
numbers is detected, so not sequential, the first open CID will be used
before using the max CID +1 or replacing the max CID. If an exact
match for IP type and APN is found, then that will still be used first.

On u-blox modems it has been observed that attempting to force down the
bearer when the modem had an active data connection, lost the connection
but the bearer is still up, and the modem is searching for the network,
ModemManager would timeout before the CGACT command could return. This
can put the modem in a state where the ModemManager state does not match
the modem's actual state of being connected.
When deactivating the current active bearer, the timeout has been
changed from 10 seconds to 45 seconds. u-blox modems can take up to 40
seconds to respond to deactivation requests through the AT+CGACT
command according to the u-blox AT command reference.
|
|
Several plugins define the specific device vid:pid pairs they
support. Let's use this information as a direct indication that
ModemManager can probe the devices.
|
|
Instead of blindly allowing to be probed all ttyACM ports that report
them as AT-capable, we will now instead forbid all ttyACM ports that
don't report themselves as AT-capable.
Also, require the modem to expose other additional ports (of any kind
usable by ModemManager) in addition to the AT-capable ttyACM port.
This update should avoid automatically probing Arduino devices that
wrongly report their exposed single ttyACM port as AT-capable.

If the reopening operation fails when attempting to recover the
previous open count, it could mean the port is already gone. We didn't
get a HUP in the TTY because the channel I/O monitoring isn't in place
during this time, so this is the best way to detect that at this
point.
And if we do see an error, we'll flag the port as forced closed so
that we do not attempt to reopen it again.

We cannot complete the flash task cancellation right away because this
may be called from within _close_internal() during a forced port close
after the TTY has gone, which would mean the object is fully disposed
already after the flash cancellation has been requested.
By making the task cancellation complete in idle, we're sure that
there will be at least one reference valid (the one in the task)
during the port close operation.

For now, including a handy method from the ublox tests that allows
comparing arrays of bands that may not be sorted.

This reverts commit ef89dd154bdeda1c727190ea8b7c66766659f919.
The PID of the ME910 is 1101, not 1011... :D

Several plugins define specific udev tags that must be available in
the device in order for the plugins to use them. Let's use these tags
as a direct indication that ModemManager can probe the devices.
In particular, this change would make all Ericsson MBM modems probed
right away also in STRICT filter mode, without needing to check the
ttyACM interface type or the available net ports.

If the signal is automatically disconnected during object disposal, we
shouldn't explicitly try to disconnect it ourselves during finalize().

This tag is completely redundant because users can whitelist the
platform TTY ports to use with the more generic ID_MM_DEVICE_PROCESS
tag, which is part of the explicit whitelist filter rule.
|
|
The udev tag that allows flagging devices that MAY be modems
(e.g. USB<->RS232 adapters) is only applicable to TTY devices, so
explicitly specify that in the tag name as well.
|
|
Until now the ID_MM_DEVICE_IGNORE udev tag was being used in the
internal blacklist of devices shipped by ModemManager when running in
either DEFAULT or PARANOID filter modes. The name of the tag is
extremely misleading because it doesn't really make the full device be
ignored, the tag only applied to TTY ports.
This commit repurposes the tag so that it applies to ANY kind of
port (e.g. TTY, NET, cdc-wdm...) and also to any kind of filter type
(i.e. also applicable in STRICT mode).
The internal blacklist shipped by ModemManager, which should NOT be
used in STRICT mode, uses a new tag name, ID_MM_TTY_BLACKLIST.
The new ID_MM_DEVICE_IGNORE tag is therefore much more usable and its
name is really meaningful. If there are users or third-party projects
adding their own udev rules with the ID_MM_DEVICE_IGNORE tag name,
they should have no problem as the new rule is more restrictive than
the old one.

The 'modem' field in _MMBaseSimPrivate is already a MMBaseModem object.
