These lists were used in the corresponding TTY_BLACKLIST and
TTY_MANUAL_SCAN_ONLY filter rules, in the LEGACY and PARANOID filter
types, which are no longer supported.
The DEFAULT_ALLOWED filter rule made sense only in the LEGACY filter
type, and therefore it is also now removed, leaving the
DEFAULT_FORBIDDEN fallback rule exclusively. In other words, there is
now no way to ask ModemManager to implicitly allow TTY ports; the only
way to do that is by explicit making the TTY ports fall in one filter
rule that would allow them.
This interface will provide support for the profile management
operations in different modem types.
This initial commit introduces support for the interface and provides
handlers for the methods that may be called in the interface.
The QmiDeviceExpectedDataFormat is specific to modules exposed by the
qmi_wwan driver, it has nothing to do with other drivers we may find
in the system like bam-dmux or ipa, which don't allow changing the
expected data format.
The port setup logic is now updated to use a new flags bitmask that
specifies which kernel data modes are supported or currently
available.
The WITH_QRTR symbol in config.h will let us know both if libqrtr-glib
is found and if libqmi-glib is compiled with QRTR support (as per the
exposed "qmi_qrtr_supported" variable in pkg-config).
Right now just with the support to setup link properties like up/down
state or the link mtu.
This features are required when using QMAP based multiplexing with the
qmi_wwan kernel driver.
The autoconf macros AX_COMPILER_FLAGS_{CFLAGS|GIR|LDFLAGS} test
for compiler and linker support of various flags, and add the flags to
the generated output.
If the command-line option '--enable-compile-warnings' is specified to
'configure', a number of additional warning options is also added to the
output. This is the default.
This update requires the presence of the GNU autoconf-archive in the
system.
The auth provider setup is a bit over-engineered. Simplify it by
making a single MMAuthProvider object that may or may not use polkit,
depending on configure options. This object is also setup as a
singleton object using the helper MM_DEFINE_SINGLETON_GETTER().
This new interface will include implementations that are shared
between the MMBroadbandModemQmi and the MMBroadbandModemMbim.
For now, it just provides a way to implement the common client
allocation methods.
This new object allows configuring the filter rules applied to the
device ports. By default, for now, it implements the same rules as the
MMKernelDevice is_candidate() method, which is obsoleted.
And only define WITH_SYSTEMD_SUSPEND_RESUME when enabled.
We already have other systemd specific features under the
--with-systemd-* name scheme, so consolidate that, given that we don't
have any other method to support suspend/resume notifications.
This logging is available if the software was build with the configure
option --with-systemd-journal.
It will be enabled by default if libsystemd is found.
The runtime parameter --log-journal enables to output of log messages
to the systemd journal.
Please note that the journal priority field has the same value as the
syslog level so no conversion is required here.
The whitelist made all platform TTYs managed by the 'atmel_usart'
kernel driver probed by ModemManager, which isn't something we want,
as most of these aren't broadband modems.
We leave the logic supporting the ID_MM_PLATFORM_DRIVER_PROBE udev tag
as there may be a case where the user does need ModemManager to probe
a given platform TTY.
During modem initialization we detected the flow control settings
supported by the modem, and selected the best one to use from them,
notifying it to the device via AT+IFC. The device was therefore
instructed to use that flow control setting for data transmission in
the TTY (i.e. not during AT control commands).
The missing thing was to also configure ourselves our end of the
serial port with the same flow control settings when getting into data
mode. By doing it ourselves, we avoid requiring any explicit setting
in pppd for flow control; pppd can assume the flow control settings
are already the expected ones.
Worth noting that all this setup is completely ignored for TTYs
exposed directly via USB.

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.
We try to combine in common envvars the compiler and linker flags shared by the
different components, and where possible, also re-using the implicit AM_CFLAGS
and AM_LDFLAGS variables that automake provides, and which apply to all objects
being built in the same Makefile.am.
The internal libmodem-helpers.la library is also renamed to libhelpers.la
Instead of providing explicit dependency rules to generate the enum types
support files before they're first used, just pre-generate them before building
anything. Maintaining the explicit dependency rules is not really worth it.
Build all targets, except for CLI tools (mmcli, uml290), with special
flags needed for collecting code coverage information when the build has
been configured with --enable-code-coverage.
Three new targets are available in the top build directory:
- `check-code-coverage' runs the test suite and generates a code
coverage report,
- `code-coverage-capture' generates a code coverage report from already
collected data, which can come in handy when one wants to see code
paths touched by a particular test,
- `code-coverage-clean' removes the collected coverage data and the
generated reports.
