ModemManager handles suspend and resume signals sent from powerd
Fixes https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/547
|
|
The modem may report the 'apn-type' field is the one to be used as
index; if that's the case, allow setting and deleting profiles based
on the given 'apn-type' field.
This change also makes the internal profile management operations use
one index field or another, based on what the protocol implements.
|
|
|
|
We let protocol implementations provide the uplink and downlink speeds
agreed with the network as part of the connect result, and we then move
them to the bearer stats in DBus.
|
|
Using "requested" as a common default for every possible
implementation works, because it can handle setups without
multiplexing capabilities (e.g. plain AT+PPP modems) and also setups
without non-multiplexing capabilities (e.g. IPA based SoCs).
But if we don't want "requested" as default, then there will be
failing cases; e.g. we cannot use "none" as default for all as it
would break IPA, and we cannot use "required" as default for all as it
would break AT+PPP setups.
So, remove the common default, it's not flexible enough.
|
|
If the user doesn't provide a specific multiplex setting, we'll
fallback to a predefined default.
For now, the default is REQUESTED.

Just triggering a connection status reload won't change the actual
bearer object state.
We change the signature of the reload_connection_status_finish()
method so that it returns the actual reloaded bearer connection
status, and so both the load_ and reload_ methods can be implemented
with exactly the same method, something that was not possible before.
Once we get the new connection status reloaded, we apply it in the
bearer object only if it's DISCONNECTED (and it wasn't DISCONNECTED
before). This should cover the true real case we're interested in, and
nothing else (i.e. we won't overcomplicate the logic attempting to
handle disconnected->connected transitions detected in the sync()
operation).

|
|
Refresh connection status on resume to confirm
that the connection bearers are still valid.
|
|
By default, fallback to "unknown" mobile equipment error when the
modem gets disconnected by the network and we don't have any way to
know a more detailed reason.
|
|
Some of the operations performed by the profile management interface
will require checking whether the operation is attempted on a profile
for which there is a known connected bearer object.
We introduce a new method to lookup a bearer in the bearer list by its
connected profile id.
|
|
Implementations that support profile management will provide the
connected profile id value in the MMBearerConnectResult returned to
the base bearer object during the connection attempt.
|
|
|
|
There is no point in providing a configurable default IP family in the
bearer object, because we can always assume IPv4 as being the only
default expected.
Simplify the logic and also provide a new method to get the normalize
the IP family, using IPv4 as default always.
|
|
This property will be TRUE if the bearer has the data session
connected through a multiplexed interface.
If the bearer is disconnected, or connected without multiplexing, the
property will report FALSE.

Each different plugin or protocol had a different connection attempt
value. E.g. QMI and MBIM both used 60s max for the connection attempt,
while the u-blox plugin had up to 180s for ECM based connection
setups.
This commit consolidates all plugins and protocols to use the same
timeout values for commands that may take long to respond, e.g. a
connection atempt under low signal quality conditions.
A value of 180s for the connection attempt steps and 120s for a
disconnection attempt step is considered. Note, though, that in some
cases (like a IPv4v6 setup attempt using QMI) we may have more than
one such long step, so this doesn't mean that a connection attempt
will always take less than 180s.
Users of the connection/disconnection APIs should be able to handle
the case where the attempt times out in their side (e.g. with a lower
DBus request timeout), and which would not mean the actual request
they did really failed. E.g. a connection attempt with a DBus timeout
of 30s may fail in the user with a timeout error, but the attempt
would still go on for as much as the plugin/protocol needs.

If the bearer implementation supports it, load stats periodically. By default
every 30s for now.
|
|
Just so that we don't have same header names in src/ and /libmm-glib.
