ModemManager 1.22.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version now requires:
** libmbim >= 1.30.0 (for the optional MBIM support)
** libqmi >= 1.34.0 (for the optional QMI support)
* The GNU autotools (autoconf/automake/libtool) support has been fully
removed, this release requires the use of the meson build system.
* Build:
** Flag types are now generated in their own files (e.g. 'mm-flags-types.h').
** A new 'fuzzer' option is available to build LLVM LibFuzzer based unit
testers.
** A new 'builtin_plugins' option is available to integrate all built plugins
within the ModemManager daemon binary. This makes the daemon load much
quicker as it doesn't dynamically load the plugins on runtime.
The most important features and changes in this release are the following:
* A new "MSG" (message) log verbosity level is introduced, which is also the
new default one if none explicitly defined. This level takes the place of the
old "INFO" level, as a level including the most important messages that should
be logged without needing to be warnings or errors. The new "INFO" level is
more verbose than "MSG" but less verbose than "DBG", and may be useful as
default in systems where active debugging of WWAN related issues is required.
E.g. all user operations triggered via DBus method calls are logged in "INFO"
level.
* Introduced the concept of "personal information" which should by default not
be included in log messages. Enabling personal information in logs requires
to run the daemon with the '--log-personal-info' option. This feature is
mostly implemented for QMI and MBIM specific logs, but hasn't yet been
included in generic daemon logs or when using the AT protocol. Changes and
fixes related to this feature will be cherry-picked and included in the
future stable branch updates.
* API:
** Added new 'Modem.Physdev' property to unconditionally publish the physical
modem device path.
** Updated the 'Modem.GetCellInfo()' method to include serving cell type and
bandwidth information in LTE and 5GNR cells.
** New 'Modem3gpp.SetCarrierLock()' method to send the list of carrier
network information to the modem.
** The 'SetLogging()' method allows a new "MSG" log level.
* Core:
** The codebase has been updated to use GTask in all operations and there are
no longer any deprecated methods from GLib being used.
** The port probing logic is now able to guess port type hints during
runtime, e.g. based on the kernel driver in use or the wwan subsystem port
'type' attributes.
** Default probing and wait times have been increased, in order to cope with
slow kernel events reporting new port additions.
* Modem interface:
** Updated the logic loading unlock retries to allow restarting the check
count based on the state reported by the device (e.g. if the SIM is
detected but not fully ready during the last expected check, a new set
of check retries is allowed).
* 3GPP interface:
** Added support for packet service state updates via unsolicited
indications.
** Added support for ignoring registration and packet service state updates
if the interface has already been disabled.
** Updated initialization sequence to allow showing IMEI even if the device
is locked.
** Logged available profiles in "INFO" level whenever they are listed.
* Simple interface:
** Logged user provided settings during a connect attempt in "INFO" level.
** Added support to abort an ongoing connect operation at any step in the
state machine, e.g. if the modem is going to be disabled.
** Added support to explicitly request attaching to packet service during
the connection attempt.
* Signal interface:
** Added logic to rate-limit printing the extended signal information with
"INFO" level, even if the actual refresh rate is higher.
* New udev tags:
** The 'ID_MM_REQUIRED' port-specific udev tag allows users to specify that
the modem must be able to succesfully probe and use the given control
port.
** The 'ID_MM_MAX_MULTIPLEXED_LINKS' udev tag allows user to specify the
maximum amount of multiplexed links the modem supports. This tag may be
set to 0 to fully disable multiplexing support in the device.
* mmcli:
** New '--messaging-create-sms-with-text' action to create a text SMS from
the contents of a given file.
** New '--3gpp-set-carrier-lock' action to send the carrier lock data to the
device.
** Updated '--modem' to always allow using the modem physdev path for lookup.
* SMS:
** Improved the parsing of 3GPP and CDMA SMS parts, fixing multiple different
errors that lead to unexpected crashes on SMS reception.
* MBIM:
** Updated device model loading logic to use an AT port if available.
** Added support for the carrier lock feature using the Google MBIM service.
** Implemented support for reporting serving cell type and bandwidth in the
cell scan operation.
** Limited the amount of different APN types usable when MS extensions are
unsupported.
** Updated packet service state info loading to use the values reported by
the device instead of attempting to guess them.
** Updated IPv6 IP addressing logic to rely on whether the provided address
is global or not to decide whether static or dynamic addressing is needed.
* QMI:
** Implemented support for detecting and processing profile change
indications, e.g. during a SIM card IMSI refresh operation.
** Implemented support for scanning LTE and 5GNR cells.
** Fixed operating mode update logic to avoid needing to receive indications,
as old devices don't support them.
** Implemented multiplexing support for Qualcomm PCI devices using the MHI
driver.
** Updated logic to read IPA tx/rx offload values from sysfs, making the IPA
support work seamlessly in multiple different Qualcomm SoCs.
** Updated logic reading the SIM card operator identifier to avoid using the
NAS service, as that sometimes involved actual network access. The new
logic exclusively uses SIM card read operations (e.g. IMSI and EFad).
** Consolidated the logic processing registration state from responses and
indications.
* Plugins:
** cinterion: implemented multiple-SIM support.
** fibocom: disabled multiplexing in the NL668, which doesn't support it.
** huawei: updated time interface to use ^NWTIME.
** quectel: added port type hints for the EG12, EC21, EM060, EM061 and new
EM120, EM160 and RM520 variants.
The following features which were backported to 1.20.x releases are also present
in ModemManager 1.22.0:
** build: new 'examples' option to allow disabling the installation of
examples.
** mmcli: improved JSON output in network scan results.
** mmcli: improved JSON output when creating SMS messages.
** MBIM: ignored SIM related indications during a SIM slot switch operation.
** MBIM: updated capabilities loading to use Microsoft Extensions if
available.
** MBIM: updated supported modes loading to use the CustomDataClass field
contents.
** QMI: fixed processing and exposing PCOs.
** cinterion: improved management of the ^SWWAN? operation.
** telit: improved support for 5G modems.
** messaging: allowed Delete operation during enabling/disabling.
ModemManager 1.20.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version now requires:
** libmbim >= 1.28.0 (for the optional MBIM support)
** libqmi >= 1.32.0 (for the optional QMI support)
* There is no longer an upstream-provided source tarball, please use the signed
git tag '1.20.0' instead to refer to the sources of this release.
* This release supports meson as the primary build system. The GNU autotools
support is considered deprecated and will no longer be used in future major
releases. The 1.20.x releases will be the last ones including GNU autotools
support.
The most important features and changes in this release are the following:
* API:
** New 'Modem.Sar' interface to allow the host to manage the SAR power level.
** New 'Modem.GetCellInfo()' method, that allows querying information about
the current serving and neighboring cells. Currently including
'cell-type' and 'serving' fields for all cell types, plus additional
type-specific fields:
*** CDMA: 'nid', 'sid', 'base-station-id', 'ref-pn' and 'pilot-strength'.
*** GSM: 'operator-id', 'lac', 'ci', 'timing-advance', 'arfcn',
'base-station-id' and 'rx-level'.
*** UMTS: 'operator-id', 'lac', 'ci', 'frequency-fdd-ul',
'frequency-fdd-dl', 'frequency-tdd', 'uarfcn', 'psc', 'rscp', 'ecio'
and 'path-loss'.
*** TDSCDMA: 'operator-id', 'lac', 'ci', 'uarfcn', 'cell-parameter-id',
'timing-advance', 'rscp' and 'path-loss'.
*** LTE: 'operator-id', 'tac', 'ci', 'physical-ci', 'earfcn', 'rsrp',
'rsrq' and 'timing-advance'.
*** 5GNR: 'operator-id', 'tac', 'ci', 'physical-ci', 'nrarfcn', 'rsrp',
'rsrq', 'sinr' and 'timing-advance'.
** New 'access-type-preference', 'roaming-allowance', 'profile-name',
'profile-enabled' and 'profile-source' fields in the 'Bearer.Properties'
property, that can also be used in both 'Modem.Simple.Connect()' and
'Modem.CreateBearer()'.
** New 'Modem.Modem3gpp.SetPacketServiceState()' method and
'Modem.Modem3gpp.PacketServiceState' property, which allow management the
explicit attach or detach to packet service on the current registered
network.
** New 'Modem.Modem3gpp.SetNr5gRegistrationSettings()' method and
'Modem.Modem3gpp.Nr5gRegistrationSettings' property, to allow management
of 5G specific settings like 'mico-mode' or 'drx-cycle'.
** New 'start-date', 'uplink-speed' and 'downlnk-speed' fields in the
'Bearer.Stats' property.
** New 'Bearer.ReloadStatsSupported' property to indicate whether reloading
ongoing stats is supported or not.
** New 'Modem.Modem3gppProfileManager.IndexField' property, to indicate which
field is to be used as unique index in the profile management operations.
** New 'Sim.SimType', 'Sim.EsimStatus' and 'Sim.Removability' properties to
improve the management of eSIM related operations.
** New 'Sim.Gid1' and 'Sim.Gid2' properties, which allow identifying SIM cards
that should have different settings applied.
** New 'Modem.Signal.SetupThresholds() method, 'Modem.Signal.RssiThreshold'
and 'Modem.Signal.ErrorRateThreshold' to allow configuring thresholds so
that the modem emits indications whenever the signal quality values change
based on those thresholds. For RSSI a delta amount of dBm can be given,
and for error rate just a boolean to enable or disable the corresponding
event.
** New 'error-rate' fields in the 'Modem.Signal.Cdma', 'Modem.Signal.Evdo',
'Modem.Signal.Gsm', 'Modem.Signal.Umts', 'Modem.Signal.Lte' and
'Modem.Signal.Nr5g' properties.
* Core:
** Detecting an eSIM without an active profile in the current SIM slot will
lead to the modem being in Failed state, in the same way as if the slot
was for a physical SIM and no SIM was inserted.
** Default amount of AT probing attempts is updated to 6, to cope with modems
that are slower to boot.
** New '--test-mbimex-profile-management' option in the daemon, to enable
support for profile management operations using the Microsoft extensions.
This is an optional feature because it requires using the 'apn-type' field
as unique index, which not all users of the profile management API may
expect.
** Implemented some initial support to automatically hide personal details
(e.g. phone numbers, SMS contents...) from logs, right now only applicable
to QMI and MBIM logs. Updated support for this feature will keep on being
integrated in future 1.20.x updates. The new '--log-personal-info' option
in the daemon allows to disable this feature completely.
** Added new filter match option for subsystem vendor id, required in several
PCI based Qualcomm modules.
** QCDM port probing will no longer automatically run for all plugins, only
in those that explicitly require it.
** Implemented support for suspend/resume detection based on ChromeOS' powerd
daemon.
** Added Cat-M and NB-IoT LPWA access technologies.
* Modem interface:
** On 3GPP+3GPP2 multimode devices, a missing SIM card will now force the
modem into Failed state, as if it was a 3GPP-only device.
* Simple interface:
** Explicitly wait for PS domain to be attached during a connection attempt.
* 3GPP interface:
** Updated to report domain registration changes altogether whenever possible
(e.g. when using the QMI or MBIM protocols).
* MBIM:
** Implemented support to use the Microsoft-defined MBIM extensions v2 and v3
whenever supported by the device. The ModemManager daemon will negotiate
which version to use with the modem, so that the highest version supported
is enabled. This negotiation applies to the whole device, so any other
user of the MBIM device will automatically start using the newly agreed
version.
** Implemented current modes switching using MBIMEx v2.0 extensions.
** Trigger explicit disconnection if a connection attempt fails.
** Modem will be flagged as unusable if 10 consecutive MBIM requests timeout.
** Enabled multiplex support for devices in the WWAN subsystem.
* QMI:
** Updated logic to by default prefer 'Signal Info' over the deprecated
'Signal Strength' operations.
** Updated logic to by default prefer 'System Info' over the deprecated
'Serving System' operations.
** Updated power state transition logic to ensure the new state is reached
before returning success to the user.
** Implemented support for the 'Modem3gppProfileManager.Updated' signal using
PDC refresh notifications.
** Modem will be flagged as unusable if 10 consecutive QMI requests timeout.
** Implemented DTMF support.
** Implemented support for automatic SIM IMSI switch detection under certain
roaming scenarios.
** Updated the logic to move the PS domain state to 'registered' based on the
DSD System Status indications.
** Updated endpoint type detection logic to be based on the net driver.
** Updated endpoint number selection to be based on the data port.
** Updated connection logic to allocate separate WDS clients per endpoint.
** Added support for PCO reporting.
* plugins:
** quectel: Added FCC unlock support for the EM05-G.
** telit: Band management updated to prefer using QMI whenever available, as
well as to detect the #BND command format automatically.
** telit: Added support for LPWA modems.
** fibocom: Implemented optional support to power down and up the modem
during the update of the initial EPS bearer settings.
** fibocom: Implemented initial EPS bearer settings management in the MA510.
** intel: New generic plugin for Intel PCI devices with vid 0x8086.
** xmm: Prefer GNSS control ports explicitly tagged via udev tags.
** foxconn: Use the new FOX QMI service to load firmware version.
** cinterion: Added support for PCIe based devices.
The following features which were backported to 1.18.x releases are also present
in ModemManager 1.20.0:
* core: added support for external FCC unlock scripts that the user must
manually enable; automatic FCC unlocking will no longer happen.
* core: added support for connection/disconnection notification dispatcher
scripts, used primarily in the openwrt integration in order to report network
initiated disconnects.
* udev: fixed shell globing patterns in rules.
* sms: default send timeout updated to 5min.
* sms: merge WDP multipart CDMA WAP messages.
* qmi: fixed capabilities management in multimode 4G/5G devices.
* mbim: fixed network initiated disconnections by not comparing context type.
* qcom-soc: plugin enabled by default in build.
* foxconn: added support for T99W265 modems.
* fibocom: added support for FM101 modems.
* cinterion: added support for PLSx3w modems.
* telit: added support for new LE910S1, LE910Cx and LN920 compositions.
ModemManager 1.18.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version now requires:
** glib2 >= 2.56
** libgudev >= 232
** libmbim >= 1.26.0 (for the optional MBIM support)
** libqmi >= 1.30.2 (for the optional QMI support)
** libqrtr-glib >= 1.0.0 (for the optional QRTR support)
* The ModemManager.service file for systemd integration provided in the sources
is updated as follows:
** 'CAP_NET_ADMIN' is now required in the 'CapabilityBoundingSet' field.
** 'AF_NETLINK' and 'AF_QIPCRTR' are now required in the
'RestrictAddressFamilies' field.
If the system where ModemManager is being integrated provides a custom
systemd service configuration, these updates should be considered.
* The LEGACY and PARANOID filter types that were allowed options in the
'--filter-policy' option in the ModemManager daemon were deprecated in
version 1.16.0 and have now been completely removed, along with the vid:pid
blocklist of devices and the vid:pid greylist of RS232<->USB adapters.
* Building from git no longer requires autoconf-archive, the needed AX_ macros
are now shipped inside m4/.
* In addition to building from a source release tarball, or building from git
checkouts using the GNU autotools suite (autoconf/automake/libtool), this
release includes the initial support for the meson build system. The meson
port is not fully complete yet, as there are some missing things in the doc
generation and test steps, but for system integration or development
purposes, the port should be fully operational. This major release, including
all its stable updates in the 1.18.x series, will be the last ones providing
support for GNU autotools. The next major release will likely be a meson-only
one, and will therefore not be based on a source release tarball any more,
but on specific git tags instead.
The most important features and changes in this release are the following:
* Data session multiplexing can now be enabled in QMI and MBIM modems, e.g. so
that multiple different APNs can be connected separately over a single
network interface. The multiplexing is disabled by default in this release,
except for cases where it's required (e.g. if non-multiplexed sessions aren't
supported) like IPA based Qualcomm SoCs. Users can request the multiplexing
support explicitly via settings when creating the connection bearer object.
In order to allow easy testing of the multiplexing feature without requiring
any additional change in the stack, a new '--test-multiplex-requested' option
in the daemon allows to switch the default (when not explicitly given by the
user) to attempt to use multiplexing.
It is worth noting that when multiplexing is enabled, the data network
interface used by the modem will be a virtual network interface created in
runtime, and will therefore have a different name than the real network
interface exposed by the modem. If there are additional settings in the
system relying on the data network interface name (e.g. iptables rules), they
may need to be updated.
* The ModemManager daemon can run now in a 'quick suspend/resume' mode, in
which no explicit data disconnection is triggered on suspend, and no explicit
device re-probing from scratch is launched on resume. Instead, the daemon
will try to refresh the state of all interfaces upon suspend, e.g. to see if
the module keeps registered to the same operator, to see if it is still
connected, and so on.
This mode of operation is useful when the WWAN module stays awake while the
host is suspended, and can be enabled with the '--test-quick-suspend-resume'
option in the daemon.
* API:
** New '3gppProfileManager' interface, providing operations on the list of
connection profiles stored in the 3GPP module. This interface is
implemented for all AT, QMI and MBIM protocols.
** New 'DisableFacilityLock()' method in the 3GPP interface, implemented for
QMI and MBIM devices.
** The 'MaxBearers' property is now deprecated, as it didn't provide any
additional information to what 'MaxActiveBearers' already provides.
** New 'MaxActiveMultiplexedBearers' property, listing how many bearers can
be connected at the same time if multiplexing is enabled.
** New settings in the bearer properties, applicable to both the
'Simple.Connect()' and 'Modem.CreateBearer()' methods:
*** 'multiplex': which allows the user to specify whether multiplexing
should be avoided ('none'), whether it should be mandatory
('required') or whether it should be enabled if available or skipped
if unavailable ('requested').
*** 'profile-id': which allows the user to request a connection attempt
with an existing profile stored in the module.
*** 'apn-type': which allows the user to specify the purpose of a given
connection, e.g. the user could create a connection to an APN
providing default internet connectivity and another one to an APN
providing access to the MMS gateway. This setting may or may not be
stored in the module itself, it depends on the type of module.
** New 'Multiplexed' boolean property in the Bearer object, specifying
whether the bearer is connected through a multiplexed interface.
** New 'ConnectionError' property in the bearer object, specifying the last
error reported by the module during a failed connection attempt or during
a network-initiated disconnection.
** Updated the list of enum values in the MMMobileEquipmentError' type,
according to the error codes defined in v17.1.0 of 3GPP TS 27.007.
* Core:
** iconv() features support is detected at runtime, and logged when the
daemon starts.
** Updated the base modem object to allow plugins to specify the types of
data ports they support, based on the specific plugin implementations,
e.g. so that a modem supporting only AT+PPP can ignore NET ports and
vice versa.
** Added support for modems exposing control ports via QRTR channels.
* Modem interface:
** The Dual SIM logic that would iterate over all slots during initialization
is updated, so that we only report the information that we can gather
without any explicit slot change. E.g. with QMI we can know whether there
is a SIM in the non-active slot, and the ICCID of that SIM, but we cannot
know the MCCMNC or the operator name of the SIM unless we change to that
slot. We must not do slot changes arbitrarily like that, and so that logic
is removed, even if we lose some of the information that we were providing
in the interface.
* Location interface:
** The multi-sentence NMEA trace support is updated to include additional
possible trace types in addition to GSV (e.g. ALM, GSV, RTE, SFI) and also
when coming from other constellations, not just GPS.
* SIM:
** New 'PreferredNetworks' property and 'SetPreferredNetworks' method,
implemented using '+CPOL' for generic AT modems and 'NAS Get/Set Preferred
Networks' for QMI modems. Several different modules and plugins (e.g.
Sierra Wireless EM7345, Telit LN930, SIM7070, all Option and Iridium
devices...) have this feature explicitly disabled due to '+CPOL' not
behaving properly (even crashing the module sometimes).
* QMI:
** The logic that decides which data mode (802.3 or raw-ip) is used in
modules managed by the qmi_wwan driver changes in this release. Until now,
if a module reported itself as configured in 802.3 mode on boot, that mode
would be the one used in normal operation. Due to the new multiplexing
feature, this is no longer true, and if possible the daemon will always
try to switch the module to raw-ip, and fallback to 802.3 only if raw-ip
is unsupported.
** Enabled both AT and QMI indications for the messaging and voice interfaces
so that new SMS and call events are reported via both channels. This
solves issues seen in the Pinephone when waking up from suspend.
** Enabled network reject indications.
** If operator name not updated through standard indications, it will be
explicitly queried with 'NAS Get Plmn Name'.
** Added support for transfer-route MT messages.
** Increased the QMI open timeout to 45s, as required by the newest modules.
** Implemented additional logic to read the status of the different facility
locks in the module.
** Updated ICCID reading logic to parse it as hex instead of BCD.
** Improved handling of the MNC PCS digit in the operations involving MCCMNC.
** Automatically run the 'DPM Open Port' logic on IPA based setups to bind
the hardware tx/rx endpoints with the logical ones in the QMI protocol.
** Implemented support for the Voice interface and its operations, not only
standard voice call management, but also support for the supplementary
services. Voice call management will be done completely using QMI, even
if the new call indications are notified via AT URCs.
* MBIM:
** Implemented support for Dual SIM in non-QMI MBIM devices, using the
Microsoft Basic Connect Extensions service.
** Increased the timeout for the MBIM_CID_HOME_PROVIDER query to 30s.
** Updated to load model string using QMI over MBIM if available.
** Increased the MBIM open timeout to 45s, as required by the newest modules.
* SMS:
** Defined a common timeout of 180s for all send operations.
* libmm-glib:
** Updated with new methods and types to handle all the DBus API updates.
** Extended with additional methods in the Location3gpp object to get/set the
full operator MCCMNC string, instead of integers without MNC PCS digit
info.
** Extended the 'ModemLocation' interface with methods to get the signaled
location updates; i.e. without requiring an explicit GetLocation(), and
obviously only supported when location signaling is explicitly enabled.
** Updated the way the internal monitored properties are handled in the
different types, now using some handy helper macros to share the same
logic among all.
* Plugins:
** zte: disabled CIND/CMER support.
** qcom-soc: added support for QRTR+IPA based setups.
** qcom-soc: added support for the WWAN subsystem instead of RPMSG.
** quectel: enabled QGPSXTRA by default when starting the GNSS engine.
** quectel: add support for EM120/160 PCIe modules.
** quectel: added Firehose update method.
** ublox: added additional URAT combinations.
** ublox: flagged UBANDSEL as unsupported in the SARA-R4 and -N4 modules.
** cinterion: added new custom MBIM based modem with shared reset operation.
** cinterion: ignored the MBIM Intel Firmware Update service completely.
** foxconn: added custom carrier config setup for the T77W968 module.
The following features which were backported to 1.16.x releases are also present
in ModemManager 1.18.0:
* core: added support for the new 'WWAN' subsystem in Linux kernel 5.13,
enabling PCIe-only modules.
* core: The charset conversion methods rework, including the avoiding of the
iconv() //TRANSLIT extension support, which isn't available in all libc
implementations.
* qmi: the logic managing allowed/preferred modes was fixed for multimode
devices like the MC7304, making sure the acquisition order preference always
had the same items.
* serial: when modem is connected with AT+PPP, ignore forced disconnections, so
that we don't take ownership of the PPP port before pppd has released it.
* foxconn: added support for the T99W175 (SDX55) module, including built-in FCC
unlock procedure.
* foxconn: added new MBIM QDU firmware update method.
ModemManager 1.16.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version now requires:
** libqmi >= 1.28.0 (for the optional QMI support)
* The 1.16.x branch will be the last one supporting the 'LEGACY' and 'PARANOID'
filter modes; standard distributions are advised to use the default 'STRICT'
mode if they aren't using it already (i.e. running the daemon without any
explicit '--filter-policy' option).
* A new 'qcom-soc' plugin is implemented to be able to use ModemManager in
Qualcomm SoCs like the MSM8916 or MSM8974. This plugin uses a combination of
RPMSG based control ports plus BAM-DMUX based network ports. This plugin is
disabled by default, even when `--enable-all-plugins` is used, and if wanted
it must be explicitly enabled with `--enable-plugin-qcom-soc`. Systems
targeting this kind of SoCs, like postmarketos, should enable it. Standard
distributions may or may not include it, up to the targeted hardware in each
distribution.
* Gentoo's 'libelogind' library may now be used to detect the systemd
suspend/resume support.
The API is backwards compatible with the previous releases, the only updates
are the following:
* Modem interface:
** Updated the 'Ports' property so that it exposes all ports that are
owned by the modem even if they are explicitly ignored and not used.
** New 'SimSlots' property that exposes the available SIM slots in the modem,
including the SIM object paths in each of them if the cards are present.
** New 'PrimarySimSlot' property indicating which of the slots in the
'SimSlots' array is the one currently active.
** New 'SetPrimarySimSlot' method to select which SIM slot in the 'SimSlots'
array should be considered active. When the switch happens, the modem will
be fully re-probed.
* Signal interface:
** New 'Nr5g' dictionary property including signal information for the 5GNR
access technology.
* SIM interface:
** New 'Active' boolean property, indicating whether the SIM object is the
currently active one.
** New 'Eid' string property, indicating the EID of the card, if any.
* New udev tags:
** New 'ID_MM_PORT_TYPE_QMI' tag to explicitly flag a port as being QMI, when
there is no other way to guess the type of port; e.g. this tag is not
needed for ports exposed by the qmi_wwan driver.
** New 'ID_MM_PORT_TYPE_MBIM' tag to explicitly flag a port as being MBIM,
when there is no other way to guess the type of port; e.g. this tag is not
needed for ports exposed by the cdc_mbim driver.
The most important features and changes in this release are the following:
* Implemented support for Multi SIM Single Standby support, for systems that
have multiple SIM slots and they can select which of them (only one) is
active at any given time. Currently implemented for QMI modems only.
* If the modem enabling phase fails in a fatal way, an implicit disabling
sequence is now run, in order to avoid leaving the modem in an inconsistent
state.
* If the connection attempt includes user/password information but no explicit
authentication type, CHAP will now be used by default instead of PAP.
* Full USB device removal events reported via udev are no longer used. The
device removal logic relies exclusively on independent port removal events,
as that logic is supported for all subsystems and kernel device backends
(e.g. also working for non-USB devices and for systems without udev like
OpenWRT).
* Added support to monitor the 'rpmsg' subsystem, but only in plugins that
explicitly require its use (e.g. the 'qcom-soc' plugin).
* New options in the ModemManager daemon:
** Added new '--test-no-suspend-resume' option to disable the runtime
suspend/resume support even if the daemon was built with it.
** Added new '--test-no-udev' option to disable the runtime udev support even
if the daemon was built with it.
* Serial:
** Also match OK or ERROR responses that are not at end of line.
* SIM:
** Force reprobing the modem if a new SIM is detected in a modem that
initially started in Failed state without SIM.
** Force reprobing the modem if the lock status cannot be read after sending
SIM-PUK, so that it transitions to the Failed state.
** Force reprobing the modem if a PUK lock is discovered after sending
SIM-PIN, so that it transitions to the Failed state.
* QMI:
** The logic no longer depends on the service version reported by each
client, the support for each feature is explicitly probed instead.
** Implemented SIM profile (eUICC) change detection.
** Support for QMI modems on kernels < 3.6 is dropped. Only kernels where the
QMI control ports are exposed in the 'usbmisc' subsystem are supported.
** Implemented additional step in the connection logic to allow binding the
WDS client to a given SIO port, required in the BAM-DMUX driver setup.
** Implemented support for the initial EPS bearer settings logic.
** Disabled explicit signal and access technology polling if indications have
been correctly enabled.
* MBIM:
** Enable SIM hot swap detection logic with QMI over MBIM.
** Allow plugins to specify explicitly that QMI over MBIM is not supported.
* libmm-glib:
** Added missing APIs to get/set RM protocol in the Simple connect settings.
* Plugins:
** gosuncn: new plugin, for now just with port type hints for the GM800.
** quectel: implemented GPS support with +QGPS.
** quectel: implemented custom time support check to prefer +CTZU=3 instead
of +CTZU=1 so that the modem reports localtime instead of UTC in +CCLK.
** sierra: added support for XMM-specific features (e.g. EM7345).
** cinterion: implemented support for the initial EPS bearer settings logic.
** cinterion: added SIM hot swap support to AT-based modems.
** huawei: updated to avoid applying multiple port type hint methods.
** huawei: updated the ^GETPORTMODE logic so that we don't assume the hints
in the response apply to specific USB interfaces.
The following features which were backported to 1.14.x releases are also present
in ModemManager 1.16.0:
* location: allow CID only updates.
* sms: allow sending/receiving UTF-16 as if it were UCS-2.
* modem: don't consider charset setup failure as fatal.
* QMI: fix reporting signal strength indications.
* QMI: fix parsing of USSD indications with UTF-16 data.
* QMI: run network registration with NAS Set System Selection Preference.
* QMI: when connection aborted, ensure network handles are released.
* MBIM: don't fail IPv4v6 connection attempt if only IPv4 succeeds.
* cinterion: improve user/password handling in AT^SGAUTH calls.
* cinterion: removed limitation to IPv4 only PDP contexts.
* cinterion: configure the PLAS9 to send URCs correctly.
* quectel: add support for MBIM devices.
* telit: add initial delay for AT ports to become responsive.
* udev: updated all AT/QCDM/GPS port type hints in all plugins to bind them to
TTY ports only.
ModemManager 1.14.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version requires:
** GLib/GObject/GIO >= 2.48.0
** libmbim >= 1.24.0 (for the optional MBIM support)
** libqmi >= 1.26.0 (for the optional QMI support)
* Build updated with several improvements:
** The build has been updated to use by default all warnings enabled by
AX_COMPILER_FLAGS(), and therefore when building the release from a git
checkout, autoconf-archive >= 2017.03.21 is now required. This new build
dependency isn't required when building from the release tarball.
** Also when building from a git checkout, beware because by default
--enable-compile-warnings=error is enabled, which implies -Werror. If
you'd like to build from git and avoid -Werror, you should explicitly use
--enable-compile-warnings=yes (to keep the warnings but without being
errors), --enable-compile-warnings=no (to disable all the extra warnings
enabled by default) or --disable-Werror (to unconditionally make all
compiler warnings non-fatal).
** Users can now preselect which plugins to build and install during
configure, with the --enable-plugin-[PLUGIN-NAME] options. The user can
also build and install all except for some, just by using the
--enable-all-plugins option followed by --disable-plugin-[PLUGIN-NAME].
By default all plugins are enabled, so all of them built and installed.
This new set of options are useful for users building custom systems
where they already know what kind of devices they're going to have, it
isn't recommended for standard distributions.
The only updates in the public API are the following:
* Modem interface:
** Added support for AT-based and/or QMI-based 5G devices, which will report
the new MM_MODEM_CAPABILITY_5GNR capability.
** Deprecated the MM_MODEM_CAPABILITY_LTE_ADVANCED capability, as it was
never used in any implementation.
* Bearer interface:
** Added additional 'attempts', 'failed-attempts', 'total-rx-bytes',
'total-tx-bytes' and 'total-duration' values in the 'Stats' property
exposed by the Bearer objects.
The most important features and changes in this release are the following:
* The daemon switched to 'STRICT' filter mode by default. The old 'DEFAULT'
mode is renamed to 'LEGACY' and is considered now deprecated. Under the
'STRICT' filter mode, the TTY blocklist and greylist are ignored, and the
port probing mechanism uses its own heuristics to guess whether a given TTY
is owned by a modem or not.
* Added a new implicit whitelist rules applicable in 'STRICT' filter mode, so
that all devices with a USB vid matching one of the vids allowed by the
different installed plugins are implicitly allowed.
* Updated daemon logging so that we always prefix the messages with a string
identifying which modem the log refers to, making it easy to grep logs for
one specific device if the system has more than one.
* Updated the probing logic to make sure we don't attempt a re-probe when the
device is gone.
* Probing logic now allows new ports detected up to 1500ms since last port
added, useful on OpenWrt setups where ports are notified one by one via
hotplug events.
* AT:
** Moved the charset definition logic to the initialization phase instead of
the enabling phase, because the feature support checks may already require
string processing based on the current charset.
** Updated manual registration operation to attempt using current charset
(e.g. UCS2) if ASCII fails.
* QMI:
** Devices using the LOC service for GNSS will now also setup the list of
required NMEA traces before starting the engine.
** Implemented 3GPP USSD support using the Voice service.
** Update carrier code if registration changes from one roaming operator to
another.
** Explicitly disable autoconnect during modem enabling phase, because it
interferes with our connection management logic.
** Fallback to raw-ip if WDA Get Data Format requests arguments, as in most
new 5G devices.
** Updated to always use the asynchronous close() operation.
** Handle disconnection indications during connection attempts.
* MBIM:
** Update carrier code if registration changes from one roaming operator to
another.
** Implement reset in Intel-based and Qualcomm-based devices.
** Avoid LTE attach config/status if unsupported.
** Updated to make sure all allocated QMI CIDs are released during shutdown.
* SIM interface:
** Don't allow sending PIN/PUK if not required.
* 3GPP interface:
** Fixed manual re-registration to the same operator.
* CDMA interface:
** Don't allow multiple concurrent activation attempts.
** Disallow empty carrier code in automatic activation.
* Bearer interface:
** Updated to avoid connection checks or stats updates while disconnecting.
* libmm-glib:
** New 'mm_location_gps_nmea_get_traces()' method to retrieve a NULL
terminated array of strings with all cached NMEA traces.
** Deprecated the 'mm_location_gps_nmea_build_full()' method.
* mmcli:
** Added a new 'any' lookup keyword for the --modem and --sim options, useful
when the system is only expected to have one single device.

All the features and fixes which were backported to 1.12.x releases are also
present in ModemManager 1.14.0.
ModemManager 1.12.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version requires:
** libmbim >= 1.18.0 (for the optional MBIM support)
** libqmi >= 1.24.0 (for the optional QMI support)
* The build allows to configure with '--with-at-command-via-dbus' in order to
unconditionally enable the Modem.Command() method to allow running AT
commands through ModemManager. This is not suggested for standard
distributions, though.
The most important features and changes in this release are the following:
* Modem interface:
** Updated logic to avoid assuming that setting bands or modes is immediate,
the daemon will now actively monitor for those updates to happen before
returning success.
* 3GPP interface:
** libmm-glib: deprecated the mm_pco_list_free() helper method.
* Simple interface:
** api,libmm-glib: deprecated the 'subscription state' property.
* Location interface:
** Fixed 'unknown' lat/long/alt numeric values.
** Added support for MSB A-GPS in addition to MSA A-GPS.
* Voice interface:
** Improved voice call management with call id detection and tracking.
** Improved detailed call state transitions on generic modems that support
call list polling.
** Added support for GSM supplementary services, including call waiting,
call transfer, call deflection, multiparty calls...
** Added emergency call support, allowing voice call to emergency numbers
even without SIM or with SIM-PIN locked.
** Deprecated all properties except for 'number' in the CreateCall()
method.
* Messaging interface:
** Updated to report SMS timestamps in correct ISO8601 format.
* Bearer:
** Improved unused CID lookup to allow selecting non-sequential CIDs.
** Disabled all AT protocol based context monitoring when PPP is used for
the connection, in order to properly sync with pppd, which should be the
one detecting the disconnections (already in 1.10.6).
* QMI:
** Improved support to list stored firmware images in Sierra devices.
** Added additional lock check retries on 'SIM not inserted' errors.
** Updated explicit registration attempt to report success only when the
target requested network is registered.
** Added MSB A-GPS support.
** Implemented automatic carrier configuration selection using PDC service
(already in 1.10.2).
* mmcli:
** New machine-readable JSON output with '--output-json'.
** Updated to allow using the modem UID to specify SIM operations.
* udev:
** New ID_MM_PORT_TYPE_AUDIO generic udev tag to identify ports that
should be used for in-band audio.
** Removed support for the ID_MM_PLATFORM_DRIVER_PROBE udev tag, as it
is no longer required given that the more generic explicit whitelist
may be used to flag which devices should be probed.
** Renamed ID_MM_DEVICE_MANUAL_SCAN_ONLY to ID_MM_TTY_MANUAL_SCAN_ONLY,
given that the tag only applies to TTYs.
** ID_MM_DEVICE_IGNORE is no longer used internally in ModemManager, and
is instead targeted to users that want to explicitly ignore specific
devices regardless of what filter type is in use (already in 1.10.6).
* dbus:
** Updated to always report the registered MM_CORE_ERROR_CANCELLED error
instead of the implicit G_IO_ERROR_CANCELLED ones generated by GLib.
* GObject introspection:
** Fixed setup to explicitly skip all non-API methods.
* Plugins:
** tplink: new plugin.
** dlink: new plugin.
** xmm: added MSB A-GPS support.
** dell,dw5821e: update to allow unmanaged GPS support on the TTY even
when raw/NMEA GPS is enabled via QMI/LOC.
** quectel: updated to allow TTY-only devices.
** telit: added GPS support.
** telit: improved band management with #BND.
** simtech: added improved voice call support.
** simtech: added support for LTE devices.
** simtech: improved signal quality reporting logic.
** simtech: added GPS support for the SIM7000/SIM7600 family.
** cinterion: added support for time updates.
** cinterion: added improved voice call support.
** ublox: added improved voice call support.
** ublox: improved band management with UBANDSEL.
All the features and fixes which were backported to 1.10.x releases are also
present in ModemManager 1.12.0.
ModemManager 1.10.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version requires:
** libmbim >= 1.18.0 (for the optional MBIM support)
** libqmi >= 1.22.0 (for the optional QMI support)
The most important features and changes in this release are the following:
* udev:
** Consolidated common tag names among all the supported plugins. E.g.
ID_MM_PORT_TYPE_GPS, ID_MM_PORT_TYPE_AT_*, ID_MM_PORT_TYPE_QCDM...
All these generic tags are included as symbols in the API, and
compatibility will be maintained for these. Custom setups of
ModemManager relying on previously available per-plugin udev tags may
need to manually port them to this new generic subset.
** New tag to allow specifying flow control settings to use in serial ports.
* Core:
** Avoid probing other protocols on TTYs tagged in udev with specific port
type tags (e.g. avoid probing QCDM if a port is tagged as AT). This allows
faster port probing and modem detection for known modem layouts.
** Implemented support to enable and handle +CGEV URCs for asynchronous
connection state updates in AT-controlled devices.
* Manager interface:
** New runtime daemon version reporting.
** New support for requesting device inhibition, e.g. so that ModemManager
stops completely using a modem device until the inhibition is released.
This feature is implemented to allow fwupd taking over of a device
completely for as long as it needs during a firmware update.
* Modem interface:
** All methods are always connected, even in Failed state.
** Allow parallel Enable()/Disable() calls.
** Deprecated redundant ListBearers() method, the read-only Bearers property
is already showing the same information.
* Bearer interface:
** New 'BearerType' property, e.g. to specify whether a bearer is the initial
LTE default bearer or not.
** Deprecated 'number' field in bearer settings. Applications do not need to
send the 'number' field in Bearer.Connect() or in Modem.Simple.Connect(),
as the setting is totally ignored.
* mmcli:
** New 'key-value' output, easier to parse by scripts than the default.
** Removed redundant '--location-get-XXX' actions, as the '--location-get'
already reports the location information for all sources.
** Removed redundant '--simple-status' action, as the same information can be
obtained through different mmcli operations.
** New manager '--inhibit-device' action and modem-specific '--inhibit', to
allow requesting device inhibition.
* 3GPP interface:
** New support for exposing the network reported Protocol Configuration
Options (PCO), to be used instead of the new deprecated Subscription
State property.
** New support for exposing the initial LTE default bearer status.
** New support for configuring the initial LTE default bearer settings.
* Location interface:
** New LTE Tracking Area Code (TAC) in 3GPP location information.
