We are pleased to announce the Mbed OS 6.11.0 release is now available.

Summary

This release doesn't contain any major new features, but we've made some changes to APIs to extend existing functionality, added an experimental API to our CAN APIs, and marked some APIs as deprecated, hence minor release increment.

Migration Guide

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

Deprecate broken TDB_EXTERNAL_NO_RBP and FILESYSTEM_NO_RBP in kv_config

14657

Summary of changes

Replaces #14490: changed from removal to deprecation due to the Mbed OS release model.
NO_RBP (no rollback protection) is intended to not require an internal TDB, however, DeviceKey, which we use to derive SecureStore's encryption key, still does. Currently, no internal TDB is created with these two configurations, meaning there's no way to store the DeviceKey and SecureStore doesn't work. The configurations TDB_EXTERNAL_NO_RBP and FILESYSTEM_NO_RBP are broken due to this design flaw.
This PR deprecates the non-working configurations, with their documentations removed but code and configurations kept with deprecation warnings. They will be completely removed from the next major release.

Impact of changes

Existing applications that use TDB_EXTERNAL_NO_RBP and FILESYSTEM_NO_RBP will still be able to compile for now, until we fully remove the two configurations in the future. But they have never been functional, so no application should have ever been able to use them.

Migration actions required

Applications that have storage.storage_type set to TDB_EXTERNAL_NO_RBP or FILESYSTEM_NO_RBP should switch to use TDB_INTERNAL, TDB_EXTERNAL, FILESYSTEM or default depending on their use cases.

Add API to get Wi-SUN Neighbor Table

14619

Summary of changes

Added nbr_info_get API to get Wi-SUN neighbor table information in mbed-mesh-api.
mesh_nw_statistics_t structure in mbed-mesh-api has been updated with more statistics of the Wi-SUN interface.
This is upstream of PR#14586

Added API to reset MAC statistics and Wi-SUN statistics

14553

Summary of changes

Added API to reset MAC statistics and Wi-SUN statistics.
This is copied from #14439

Implement polymorphism for CAN driver

14336

Summary of changes

This PR introduces experimental polymorphism for the CAN C++ API. This allows alternate implementations (eg: external CAN interfaces) that are compatible with the internal implementation.
See #13209 for the surrounding discussion.

Impact of changes

None, it only affects the user if they have the EXPERIMENTAL_API feature enabled.

Migration actions required

None

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
