Features

This release added the following new features:

Modem Services

· Modem Services are now supported on a CDMA network. See Modem Services

Build Tools

·      Xdef files:
- rename limits in .adef files.
- warn if using a real-time priority level and cpuShare limit for the same process.
- curly braces now mandatory for all non-trivial .Xdef file sections.
- warn if file related limits are in conflict with each other.
- C++ support
- cflags, cxxflags, and ldflags sections are now supported in Component.cdef files.
- .adef support for config ACLs: clients and services must now be explicitly bound. Please read the documentation on bindings carefully.
- "import", "export", and "files" sections have been removed:
    - .adef: replaced "import" with "requires" and replaced "files" with "bundles"
    - .cdef: replaced "import" with "requires" and replaced "export" with "provides".
- .cdef now also supports "requires" and "bundles" sections with "dir" and "file" subsections.
See Definition Files

- rename start/stop functions
- BITMASK support
- support for nested USETYPES
- output gcc style error messages
See ifgen

· mk tools support C++-specific compiler flag. See mktools

On-Target Runtime

· Legato Threading API to initialize a non-Legato thread. See Using Legato APIs from Non-Legato Threads

· Time-of-Day Service.

· support for multiple open and close handlers on an IPC service.

On-Target Tools

· script on target for framework installation.

· tool to set a static MAC address on a dev target. See Set MAC

· embedded tool with unified interface for Linux image.

Linux BSP

· upgrade to Yocto 1.6.1 (from 1.4.1)

· power management and wake lock functions on Yocto Linux

· Yocto allow serial port console choice through AT!MAPUART

· ntp option for time of day service

Fixes

These fixes were included:

Modem Services

· Audio cooperative mode is now available; audio services can be access from Legato APIs and through modem services.

· le_mrc_GetNeighborCellsInfo() provides neighbor cell info for GSM/UMTS/LTE networks.

· pa_mrc_GetSignalStrength() provides HDR RSSI info for CDMA and TD-SCDMA.

· Resolved issue with stopping DTMF decoder.

· Resolved SMS storage configuration, message listing, and delete issues.

· Updated le_sim API to return MCC/MNC using string.

Data Connection Services

· Resolved issue with stopping IPv4v6 session with le_mdc_StopSession().

· Resolved issue with using different profile settings to establish a data connection.

· Retained the default gateway setting after a data connection.

eCall Services

· eCall services are enabled during build time by setting the INCLUDE_ECALL flag to 1
e.g.: make ar7 INCLUDE_ECALL=1

Developer Tools

· Corrected application installation procedure to prevent changing the rootfs user/group IDs.

· Updated Legato framework installation and start up scripts to improve the installation process.

Framework Supervisor

· Improved Supervisor’s ability to clean up sandbox resources.

On-Target Runtime

· Target platform can now be identified using le_info_GetDeviceModel().

· Config tree: Improved event triggers and callbacks.

· Config tree: Improved handling of edge conditions.

· Config tree: Improved precision on floating point values.

Linux BSP

· Resolved kernel panic issue when removing and inserting USB cable.

· I2C can now be used concurrently with UART2.

· Yocto patches for the following Shellshock Vulnerabilities:
- CVE-2014-6278
- CVE-2014-6277
- CVE-2014-7186
- CVE-2014-7187
- CVE-2014-7169
- CVE-2014-6271

Notes

IPC binding changes

As a result of introducing access control to the service directory, it's now mandatory to bind clients and services in your .adef files. See Definition Files

A new tool has been created to query the status of clients and services using the service directory. See Service Directory tool

Wakelock patches and userspace suspend/resume functions

Patches have been merged in the kernel to support auto-sleep, user-space interface to wake locks and EPOLLWAKEUP. It's still a work in progress, but it's possible to enable auto-suspend in Linux by:

echo mem > /sys/power/autosleep

This will function as long as there are no devices causing constant interrupts.

Using Legato APIs from a Boost thread

Documentation for this feature has been added to the Thread API Using Legato APIs from Non-Legato Threads.

Here's a code sample:

static void* ThreadMain(void* threadParam)
{
     le_thread_InitLegatoThreadData("thread name");
     // Do something...
     le_thread_CleanupLegatoThreadData();
     return NULL;
}
int main(void)
{
      pthread_attr_t* attrPtr;
      // Initialize thread attributes how you want them...
     pthread_t handle;
     int result = pthread_create(&handle,
             attrPtr,
             ThreadMain,
             NULL); // <- thread param

    // Do some stuff in the main thread...
    return EXIT_SUCCESS;
}

Known Issues

Data connection

It is currently only possible to have one mobile data connection at a time using the Legato APIs.

Definition Files
