ModemManager 1.8.0
-------------------------------------------
This is a new stable release of ModemManager.
The following notes are directed to package maintainers:
* This version requires:
** GLib 2.36.0
** gettext 0.19.8 (for the optional rebuild of documentation)
** libmbim >= 1.16.0 (for the optional MBIM support)
** libqmi >= 1.20.0 (for the optional QMI support)
** libsystemd >= 209 or libsystemd-login >= 183 (for the optional suspend
and resume support)
** libsystemd >= 209 (for the optional systemd journal support)
** polkit >= 0.97 (for the optional PolicyKit support)
* This version no longer requires:
** intltool (replaced by new features in gettext)
* Distributions using systemd should explicitly use the following configure
options:
** '--with-systemd-suspend-resume': the only supported source for suspend and
resume events is now systemd, so the previous '--with-suspend-resume=[]'
option was renamed.
** '--with-systemd-journal' to use the new journal support.
* Distributions wanting to avoid ModemManager poking TTY ports that isn't
supposed to touch may start using the new 'STRICT' filter policy, given
as an option to the ModemManager daemon (e.g. patching the default systemd
service file provided). See below for more info about the filter policy and
the side effects of using the STRICT approach:
** E.g. ModemManager --filter-policy=STRICT
The most important features and changes in this release are the following:
* New 'filter policy' setting in the ModemManager daemon to decide which ports
are probed and how. Currently these levels are defined:
** WHITELIST-ONLY: Only devices or ports explicitly whitelisted with the new
'ID_MM_DEVICE_PROCESS' udev tag are probed.
** DEFAULT: All ports are allowed to be probed except for the ones explicitly
greylisted as RS232 adapters or completely blacklisted. This is the
default approach that was used until now, and the default as well in this
release if a different one isn't requested.
** STRICT: The daemon defines a set of heuristics to try to detect modems and
ports to probe. Only the TTY ports that are very very likely to be modem
ports are probed, therefore completely avoiding the need of having a
separate blacklist or RS232 adapter greylist. But note that this policy
may end up ignoring some devices, like TTY controlled modems without an
associated network port.
** PARANOID: This is equivalent to running the STRICT mode but also applying
the blacklist and RS232 greylist filters explicitly.
* Device 'naming'. This release includes logic to allow 'naming' devices with
the ID_MM_PHYSDEV_UID udev tag, so that the names can then be used in e.g.
mmcli and also exposed in the 'Device' property in the Modem interface. This
new setup makes it possible to give the devices unique names that are kept
across reboots.
* Allow skipping the automatic scan for devices in the daemon with the new
'--no-auto-scan' daemon option. Instead, the daemon may be called with the
'--initial-kernel-events=[PATH]' option including a predefined list of ports
or otherwise get the port additions reported during runtime with the
mmcli --report-kernel-event=[] command.
* Allow building and running without 'udev'. In this setup, the previously
explained '--no-auto-scan' is enabled by default, so ports are not
automatically detected .Note that this setup is not suggested for standard
distributions: if udev is available in the system, it is the preferred method
to manage the port addition and removal.
* SIM hot swap. The core includes the needed logic to support SIM hot swap in
the different devices, although for now it's only tested for Telit and MBIM
modems. If a SIM hot swap is detected, the modem is flagged as failed and
reprobed from scratch.
* Connection status monitoring logic. In order to try to detect network
initiated disconnections, a generic setup is provided to plugins so that they
can implement explicit connection status checks that would be executed
periodically.
* New support for 3GPP CSFB states and operation modes. We now support
registration states reported as "SMS only" or "CSFB not preferred", and
provide APIs to set and get the "UE mode of operation for EPS".
This version comes with the following new features:
* Build and system:
** Updated the systemd service file with additional security related rules.
** Added support for systemd journal logging.
** Updated most of the code to use GTask instead of the deprecated
GSimpleAsyncResult based operations.
** ChangeLog is built from git during the dist tarball generation.
* New translations: Polish, Brazilian Portuguese, Slovak, Hungarian, Czech,
Ukrainian and Swedish.
* API:
** Defined additional GSM, UMTS and LTE frequency bands.
** The MMModemBand enumeration values (EUTRAN, UTRAN and CDMA) have been
renamed to consolidate how they are defined. A compatibility layer has
been provided to avoid breaking the API.
** New 'HardwareRevision' property in the Modem interface.
** New 'EpsUeModeOperation' property and 'SetEpsUeModeOperation' method in
the Modem 3GPP interface.
* Core:
** Updated libqcdm to load signal strength from QCDM EVDO Pilot Sets.
** Updated udev rules with new per-vendor rules for quicker processing.
** Explicitly ignored ports are never probed now, but they will be reported
as owned by the device and exposed in the Ports property.
** New 'ID_MM_TTY_BAUDRATE' udev tag to specify the baudrate to use in RS232
TTY ports.
** If using UCS2, still assume that the operator name may be given in ASCII.
** Explicitly open QCDM ports anytime it's needed, instead of assuming they
are open when enabled.
** Query supported ME event reporting options and automatically set the best
choice based on the supported ones.
** Query supported flow control modems and automatically set the best choice
based on the supported ones.
** Explicitly configure flow control settings on the TTY as soon as it is
connected, only applicable for RS232 devices.
** Implemented generic unlock retries loading.
* MBIM:
** Explicitly reprobe the modem when the mbim-proxy is detected dead.
** Workaround implemented to keep track of the PIN1 unlock retries as the
protocol isn't very good allowing this.
** Load and expose HW revision.
* QMI:
** Explicitly reprobe the modem when the qmi-proxy is detected dead.
** Load and expose HW revision.
** Detect port closed and forbid client allocation operations.
** New optional connection status monitoring support, enabled by default for
the Netgear AC341U.
* Location interface:
** Disabled by default for MBIM modems.
* Messaging interface:
** Try decoding with UTF-16BE when UCS-2 reported.
* Plugins:
** u-blox: new plugin, currently supporting the TOBY-L2 and the TOBY-L4.
** quectel: new plugin, supporting generic AT/QMI based modems.
** cinterion: implemented support for devices exposing a WWAN network
interface.
** cinterion: support changing modes in LTE capable devices.
** cinterion: added GPS support for devices controlled only with AT^SGPSC.
** cinterion: use ^SIND unsolicited messages for access tech reporting.
** huawei: implemented Signal interface.
** telit: added support for RS232, QMI and MBIM modems.
** novatel: cleaned up registration state and access tech reporting.
** novatel-lte: implemented unlock retries loading.
** dell: speed probing time up and reduce udev dependency.
** mbm: added GPS support for the Dell DW5560.
The following features which were backported to 1.6.x releases are also present
in ModemManager 1.8.0:
* Build and System:
** Explicitly use -DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_2_36 and
-DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_36 so that we don't get warnings
for GLib features that are flagged as deprecated in newer versions.
** Dropped After=syslog.target rule in systemd service file.
* Core:
** Improved detection of 4G-only modems.
** TTY is set as connected as soon as ATD replies.
** Removed the default ID_MM_PLATFORM_DRIVER_PROBE whitelist.
* Signal interface:
** Report RSCP if available.
** New generic implementation of the Signal interface in AT-based devices
using AT+CESQ.
* QMI:
** Run FCC auth sequence if "InvalidTransition" is reported when going
online.
** Added WDS reporting event support.
* Plugins:
** huawei: let the E3372 run NDISDUP via TTY (when the exposed cdc-wdm is
non-functional).
** telit: added support for the GE910.
