ARMmbed/mbed-os mbed-os-6.13.0

on GitHub

We are pleased to announce the Mbed OS 6.13.0 release is now available.

Summary

The main changes in this release are updates to existing functionality and APIs; so the addition of a RawCan class, Cortex-A5 support, changes to the BLE manual security manager functionality and greentea CMake tests refactored for supporting PSA.

Migration Guide

This section lists specific changes which are part of this release and may
need special attention.

CMake: Add CMake to mbed-psa greentea tests

14828

Summary of changes

• Changed mbed_greentea_add_test macro to require TEST_SOURCES for all files, removing assumption of main.cpp
• Refactored all pre-existing greentea tests to add main.cpp using TEST_SOURCES
• Added a CMakeLists.txt for each test suite in Mbed OS PSA.
• Moved /pal and /val directories into a separate /test_abstraction_layer directory and combined them into one CMake target, which is linked to by the test suites that require them.
  Fixes #14680

Impact of changes

None.

Migration actions required

None.

BLE: Manual BLE security manager db synchronisation

14824

Summary of changes

Adds new BLE API call to manually attempt to synchronise the security manager DB.

Feature: Make changes for Cortex-A5 support

14718

Summary of changes

It's a PR that add Cortex-A5 support for mbed-os custom targets.
Unify some __CORTEX_A macros.
__MBED_CMSIS_RTOS_CM and __MBED_CMSIS_RTOS_CA9 have been removed from CMake as they're not used anymore.

drivers: Add RawCan object

14688

Summary of changes

RawCAN class (unlocked apis) is added, which can be used in case if CAN object is accessed by a single thread.

Specific for ST CAN HAL implementation:
can_read is deferred to thread context when rx interrupt is enabled.
As can_read is protected by mutex(mutex is not allowed in ISRs in Mbed) and read is only possible way to clear interrupts in bxCAN in STM controllers, reads are to be deferred to thread context.

CYW43XXX: Add generic transport layer

14227

Summary of changes

Aim of this pr is to add a generic transport layer to COMPONENT_CYW43XXX using unbuffered uart. CYW43XXX_UNBUFFERED_UART directive has been added to keep Cypress hal support available.
40fd126 Adds then CYW43XXX support to PORTENTA_H7 target.

Impact of changes

COMPONENT_CYW43XXX

Known Issues

We publish Mbed OS as a collection of modules on GitHub. Issues are raised in the specific repositories and then tracked internally. The purpose of this section is to provide a single view of the outstanding key issues that have not been addressed for this release. As such, it is a filtered and reviewed list based on priority and potential effect. Each item summarizes the problem and includes any known workarounds, along with a link to the GitHub issue (if applicable). We welcome any comments or proposed solutions.

For more information about an issue, contact us on the forum.

TLS: IP addresses in the X.509 certificate subjectAltNames

• Description: Parsing IP addresses in the X.509 certificate subjectAltNames is not supported yet. In certificate chains relying on IP addresses in subjectAltNames a BADCERT_CN_MISMATCH error is returned.
• Workaround: merge branch https://github.com/ARMmbed/mbedtls/tree/iotssl-602-san-ip into your copy of Mbed TLS before building the application. It is still in EXPERIMENTAL stage, use it on your own responsibility!
• Reported Issue: Issue reported by a customer in email.
• Priority: MAJOR

TLS: Mismatch of root CA and issuer of CRL not caught

• Description: The x509_crt_verifycrl() function ignores the CRL, when the CRL has an issuer different from the subject of root CA certificate.
• Workaround: Make sure that the issuer of the CRL and the root CA certificate's subject are the same before passing them to x509_crt_verifycrl().
• Reported Issue: Reported by a partner.
• Priority: MAJOR

TLS: Self Test Failure with Some Hardware Accelerators

• Description: Most HW acceleration engines (if not all) require the parameters to be from contiguous memory.
  All the self tests use test vectors that are defined in the .bss section, which means these are not contiguous. This causes the self test to possibly fail, when implementing HW accelerated engines.
• Workaround: There are no known workarounds.
• Reported Issue: Reported by the development team.
• Priority: MAJOR

TLS: Hardware-accelerated hash creates CBC padding oracle in TLS

• Description: The current countermeasures against CBC padding oracle attacks in Mbed TLS call a low level internal API. The implementation of this API might not be possible with the hardware accelerator API and even if it is, the timing might still have detectable differences. The lower level API is called out of sequence and accelerators that are not aware of this might crash.
• Workaround: Keep MBEDTLS_SSL_ENCRYPT_THEN_MAC enabled in mbedtls/config.h and enable the Encrypt-then-MAC extension (RFC7366) on the peers side.
• Reported Issue: Reported by the development team.
• Priority: MAJOR

Crypto: Mbed OS ATECC608A example fails to build with IAR

• Description: The current ATECC608A secure element example fails to build with the IAR toolchain. The Microchip-provided cryptoauthlib library does not build with IAR.
• Workaround: Use a different toolchain, like GCC_ARM.
• Reported Issue: MicrochipTech/cryptoauthlib#116
• Priority: Minor

Wi-SUN Hardfaults with IAR compiled image with Mbed OS 5.15.0

• Description: Mesh Wi-SUN FAN may HardFault in rare occasions with IAR8 compiled binaries during initial network connection.
• Workaround: The workaround is to use other compilers.
• Reported Issue: IOTTHD-3898
• Priority: Major
