LoRaWAN AS923 Add SUB_REGION AS1..AS4

15320

Summary of changes

This Change add sub regions for AS923 according to the https://resources.lora-alliance.org/technical-specifications/rp2-1-0-3-lorawan-regional-parameters

Impact of changes

Able to use LoRaWAN in countries that moved to AS923-AS2, AS3 and AS4, while defaulting to AS1.
Added in connectivity/lorawan/mbed_lib.json a setting that defaults to AS1 sub region and thus defaults to the traditional AS923 Region.

"phy-as923-sub-region" : {
"help": "AS923 sub region: AS1, AS2, AS3, AS4",
"value": "AS1"
}

We are pleased to announce the Mbed OS 5.15.9 release is now available.

Summary

We anticipate this release to be our final Mbed OS 5.15.x release as we have fulfilled our commitment of a two year support period for Mbed OS 5.15. We continue to focus our support efforts on Mbed 6 and encourage anyone who hasn’t yet migrated from Mbed 5.x.x to Mbed 6 to do so.

The contents of this release are predominantly defect fixes plus documentation changes to address a security vulnerability identified in the Mbed BLE implementation, which can be avoided by using full encryption instead of signed writes.

Migration Guide

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

Bluetooth: Inform privacy risk of using signed writes.

15282

Summary of changes

The Cordio stack uses a single CSRK. It can be used by a
malicious device to track the Mbed OS application if signed
writes are used.
This PR documents the issue and explain workaround an application can
adopt.

connectivity tests: Early test skip

14771

Summary of changes

Adding mbed-os subdirectories that are not required for a specific project to .mbedignore is a good way to reduce compilation time. Sometimes it happens that tests depend on ignored files, which causes the test-build to fail even though the corresponding feature/component is not configured. The reason is that the conditional that skips the test is placed after the includes.

mbed-os-5.15: Added new start methods to Wi-SUN BR with WisunInterface parameter and deprecated the old ones

14464

Summary of changes

Previously WisunBorderRouter start() used NetworkInterface type for mesh interface, although only WisunInterface type is possible for the call. Added a new overloads of the start with the WisunInterface as mesh interface type and deprecated the old ones. This makes the calls stricter about the interface type and safer. It also allows to remove the reinterpret_cast that causes
compiler warning on ARM compiler.

Migration Guide

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

New feature: send/recv message implementation added to network stack

15040

Summary of changes

This PR is continuation of another stale PR: https://github.com/ARMmbed/mbed-os/pull/14847. I am opening this one, as I didn't have access to push to the fork created by other developer.
I have added few changes related to unresolved comments:

• function names were changed from socket_sendmsg/socket_recvmsg to socket_sendto_control/socket_recvfrom_control.
• default implementation of this functions was provided in the NetworkStack class to not break the existing API. This was the issue that caused tests to fail in the previous PR.
• MsgHeaderIterator accesses elements on the aligned addresses
  .

SFDP: Add support for multiple configurations and sector maps

14989

Summary of changes

Fixes #12574
This PR adds to following changes, to support CYW9P62S1_43012EVB_01's QSPI flash (S25FS512S):

• A Sector Map Parameter Table contains a sequence of the following descriptors:
• (Optional) configuration detection command descriptors, one for each command to run to determine the current configuration. This exists only if the flash layout is configurable.
• Sector map descriptors, one map for each possible configuration. On a flash device with a non-configurable layout, there is only one such descriptor/map.
  Previously we only supported the non-configurable case with a single descriptor. This PR adds support for multiple configurations and provides a positive unit test case.
• To be able to run configuration detection commands, a callback provided by each block device and used by the SFDP class needs to take additional parameters: address size, instruction and dummy cycles. Their values come from sector map descriptors in the SFDP table. This PR changes the callback interface, and updates callbacks implemented by SPI, QSPI and OSPI block devices to the extended interface.
• A quirk is provided for Cypress S25FS512S flash device's inconsistent register value: This device's SFDP table suggests checking CR3NV[1], which needs to be 1 in order for the config detection algorithm to work. But the actual hardware has value 0 instead. This has been discussed before on the Internet (e.g. on a Linux mailing list) - it's not possible to change a value in hardware that has been in production for years.
• Two of the three configurations of S25FS512S have eight 4KB sectors (32KB in total) overlaying a 256KB sector. This type of partial overlay is not current supported by Mbed OS's BlockDevice and SFDP parser. A quirk is provided to ignore the 4KB sectors and only use the 256KB sectors.
• Fixes of a few preexisting issues we found.
  More details in commit messages.

We are pleased to announce the Mbed OS 6.14.0 release is now available.

Summary

The main changes provided by this release are upgrades of the Fat Filesystem to version R0.14b and CMSIS to 5.8.0, both bringing improved stability and reliability. We've also added a SPI NAND block device driver for using SPI NAND Flash, like Macronix Flash MX31LF4GE4BC.

Migration Guide

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

FatFs: upgrade to R0.14b

14911

Summary of changes

Current upstream version of FatFs was now R0.14b with a lot of fixed since R0.13a. LINK
So we migrated Mbed-OS modification in R0.13a back to R0.14b and change some that affect in FATFileSystem.cpp

Impact of changes

FatFs version upgrade that may introduce new regression from upstream.

Migration actions required

FatFs has been upgraded to R0.14b. This comes with the following API changes requiring migration for direct users of FatFs. Users of the Mbed OS C++ class FATFileSystem do not need to change their use of FATFileSystem.
f_mkfs() now takes a MKFS_PARAM *opt instead of a BYTE opt and DWORD au.
f_fdisk() now takes an LBA_t ptbl[] instead of a DWORD *szt.

CMake: tests: Support skipping unsupported test with reason

14902

Summary of changes

Fixes #14856
Add a new argument TEST_SKIPPED to mbed_greentea_add_test() to indicate a test is skipped and give a reason (e.g. the Mbed target and/or configuration does not provide what the test requires).
The skip reason of a test is printed when running tests with ctest, and the test is marked as "Skipped" in the test report.
As a showcase, use this mechanism to skip the PSA Attestation test if baremetal is used or PSA and Experimental API are unavailable. Also update the ticker test (whose CTest support was added in #14892) to skip if microsecond ticker is unavailable.

Update CMSIS to 5.8.0

14900

Summary of changes

Update CMSIS to 5.8.0. It brings lot of fixes, see https://github.com/ARM-software/CMSIS_5/releases/tag/5.8.0
We again had some breakages, mainly it was arm compat (workaround implemented).

Dont require icetea

14880

Summary of changes

Remove icetea requirement.

Impact of changes

icetea is no longer listed as a default dependency.

Migration actions required

If you require icetea, you must install it separately as it is no longer listed as a default dependency of mbed-os in requirements.txt.

Add config macros for device-variant, freq-support and xtal config

14730

Summary of changes

Fixes #14726 by adding config macros for device-variant, freq-support and xtal config.
Settings these macros to -1, the selection pins are used.

add SPI NAND Block device driver

14397

Summary of changes

Add SPI NAND block device driver for using SPI NAND Flash like Macronix Flash MX31LF4GE4BC.

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.
https://github.com/ARMmbed/mbed-os/commit/40fd126915e592ed53143ecbdbcbe5a55184c9f1 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: https://github.com/MicrochipTech/cryptoauthlib/issues/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

Using this release

You can fetch this release from the mbed-os GitHub repository, using the tag "mbed-os-6.13.0".

If you need any help with this release please visit our support page, which provides reference links and details of our support channels.

We are pleased to announce the Mbed OS 6.12.0 release is now available.

Summary

The main changes in this release are further enhancements to connectivity with changes to socket APIs and to the Mesh support for Wi-SUN.

Support for one new target is added too:

• Nuvoton M2354 - https://os.mbed.com/platforms/NUMAKER-M2354/

Migration Guide

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

LWIP Broadcast socket option added

14752

Summary of changes

This PR adds Broadcast socket option

Impact of changes

No impact

Migration actions required

Not needed

Fix 'netsocket: several dynamic allocation results not checked' (#14210)

14740

Summary of changes

This changes adds std::nowthrow and the checks for allocation failure to all places in the netsocket portion that lacked it. This change addresses #14210.

Impact of changes

add_event_listener in NetworkInterface now returns an error if the method fails. Previous attempts to add the event listener would attempt to use an unchecked standard dynamically allocated ns_list_* item.
In other cases, the dynamically allocated items will now be checked, and if unsuccessful, will return after cleaning up any outstanding issues.
TCPSocket::accept will now check that its own internally allocated new TCPSocket call will succeed, and if not, will clean up the stack resources. This should help when memory is low but an incoming connection requests a connection when the TCPSocket is listening.

Migration actions required

As new calls are now handled, code that did not check against this failure may now check for failure and handle it at the application layer.
add_event_listener now returns nsapi_error_t instead of void. The two return values possible are NSAPI_ERROR_OK and NSAPI_ERROR_NO_MEMORY in the case of memory allocation failure.

Mesh api: Added PHY mode, channel plan IDs and configuration functions

14629

Summary of changes

Support for Wi-SUN FAN v1.1 PHY mode ID and channel plan ID in Mesh API.

• Enables using OFDM modulation with Wi-SUN stack.
• This change is copied from PR: https://github.com/ARMmbed/mbed-os/pull/14161
  Implemented domain configuration functions in mesh API:
• Functions will set, get and validate the parameters using corresponding Nanostack API.
• This change is copied from PR: https://github.com/ARMmbed/mbed-os/pull/14251

Enable the RWW function of Macronix Flash MX25LW51245G in OSPI block device driver

14221

Summary of changes

Update PR #12644.
Add source code about RWW(read while write) in OSPI block device driver for using the RWW function Macronix octaflash MX25LW51245G to improve performance.

Impact of changes

Enable the RWW function of MX25LW51245G.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/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

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 https://github.com/ARMmbed/mbed-os/pull/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

Using this release

You can fetch this release from the mbed-os GitHub repository, using the tag "mbed-os-6.11.0".

If you need any help with this release please visit our support page, which provides reference links and details of our support channels.

We are pleased to announce the Mbed OS 6.10.0 release is now available.

Summary

The main feature we are releasing is to introduce a new standard for the definition and usage of pin-names, with the goal of simplifying this for Mbed developers looking to port their code between development boards. We'll publish a blog providing more details shortly, and would like to publicly thank both Analog Devices and ST Microelectronics for their contributions and collaboration on these changes.

Migration Guide

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

Remove ownership/acquire in QSPI/OSPI driver

14437

Summary of changes

This PR removes the concept of peripheral acquisition and ownership in the QSPI driver. Its implementation is currently incomplete and undocumented, and has caused problems in some cases (see 11230 12678 12680).

Impact of changes

In cases where multiple instances of QSPI/OSPI are used with the same underlying peripheral, the QSPI/OSPI driver will no longer re-initialize the underlying peripheral to the appropriate configuration when switching instances. The application must call init when switching instances.

BLE: replace obsolete services with the new services repo

14436

Summary of changes

We are removing the old and broken ble services in favour of the external services repository.

Standard Pin Names

14381

Summary of changes

This PR introduces standard pin names for Mbed and migrates a number of ST targets to this standard. It also includes compliance testing tools based on static analysis and Greentea tests, and adds target markers to PinNames.h files so that they can be reliably matched to their corresponding target.

Implement polymorphism for DigitalIn/Out/InOut

13209

Summary of changes

In some IO-constrained applications, it is necessary to use a GPIO expander like the I2C-based MCP23008. To maintain compatibility with existing libraries that require a DigitalIn/Out/InOut handle, it would be beneficial to be able to subclass one of these classes and retarget the read/write, etc calls. This would enable an MCP23008 driver to provide DigitalOut-like objects that abstract away the intermediate I2C transfers. These objects can then be passed to older APIs using DigitalOut pointers.
For this to work properly, some of the DigitalIn/Out/InOut class methods must be made virtual. This PR accomplishes this.
I would encourage Mbed to consider "virtualizing" many of the other hardware drivers for similar use cases.
See #12387 for a similar discussion concerning retargetting Mbed's CAN API to an external SPI-based CAN controller/transceiver.

Impact of changes

None. This should not affect current users of these APIs in any functional way. Code size may be slightly increased due to the addition of virtual tables and new functions.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/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

Summary

The main new functionality delivered as part of this release is support for the current 1.2 version of the TF-M reference software provided by the Trusted Firmware project. TF-M is our recommended secure side software for a Platform Security Architecture-compatible MCU platform. You can find out more on the 1.2 features here: https://www.trustedfirmware.org/blog/tfm-v1-2-blog/

Both the Arm provided PSA platforms, the Musca B1 and Musca B2 have been updated to support this new version of TF-M.

CMake: support signing TF-M targets with post binary hooks

14361

Summary of changes

Changes:

• Add a post binary hook to sign TF-M targets: mbed_post_build_tfm_sign_image() (should work for any TF-M v1.2+ targets with secure and non-secure images in separate MCUboot slots). This was refactored from the existing tools/targets/ARM_MUSCA.py.
• Apply the signing hook to ARM_MUSCA_B1 and ARM_MUSCA_S1 targets.
• Copy the signing keys to each target's own directory, as per the new tools' convention (the old key paths are kept for compatibility of CLI 1 - to be deleted eventually).

Impact of changes

Images built for Musca B1 and S1 with Mbed CLI 2 are now signed and able to run on the targets.

Migration actions required

None.

Update TF-M support to v1.2

14354

Summary of changes

This PR brings in all the changes to update trusted-firmware-m support from v1.1 to v1.2:

• Mbed TLS 2.24.0 as required by TF-M v1.2
• TF-M v1.2 targets: PSA APIs from TF-M
• Support for ARM_MUSCA_B1 and ARM_MUSCA_S1 (configurations, bootloader binaries, secure binaries and signing scripts, etc.)
• Continued availability of psa_set_key_enrollment_algorithm() - deprecated, included for backward-compatibility only, to be removed from future TF-M updates
• Miscellaneous fixes to make sure all supported PSA targets work, see the commit history for details
• Changes in the trusted-firmware-m (link) and tf-m-tests (link) repositories to enable Mbed OS integration. Note that some of the changes have been upstreamed.
  Just as before this update
• CYTFM_064B0S2_4343W remains on TF-M v1.0, supporting mbed-os-example-psa but not mbed-os-tf-m-regression-tests. Any updates to this target are maintained by Cypress.
• Mbed PSA (non-TF-M) targets (e.g. K64F) continue to support mbed-os-example-psa. Note that Mbed PSA's APIs currently lag behind these of TF-M.
  The following have been removed:
• ARM_MUSCA_A as an Mbed target
• Integration of TF-M v1.1 (replaced by v1.2)
• <TARGET>_NS aliases for ARM_MUSCA_B1 and ARM_MUSCA_S1
  Not yet included in this PR, to be added in the very near future:
• Image signing for ARM_MUSCA_B1 and ARM_MUSCA_S1 with Mbed CLI 2. Until we add this, please use Mbed CLI 1 for now.

Impact of changes

See the PR description for targets that are impacted.

Migration actions required

From the perspective of Mbed OS support, applications for ARM_MUSCA_B1 and ARM_MUSCA_S1 should continue to work as before.
A board running the TF-M v1.1 firmware should be able to update to the v1.2 firmware without resetting data (verified on Musca targets), though downgrading is not possible.
Any references to ARM_MUSCA_B1_NS and ARM_MUSCA_S1_NS as target names should be changed to have _NS removed from the names.

Add lw ip opttion for rdnss

14343

Summary of changes

Added Options to turn on RDNSS using from ICMPv6 Router Advertisements (RFC5006)
and output packet queueing.
Default setting in mbed_lib is the same as before and leaving features to be turned off.

Impact of changes

RDNSS option takes about 256 bytes of flash and each DNS entry needs 128 bytes of RAM.
Outgoing packet caching avoids dropping packets during MAC address resolution. Requires increased RAM size for lwIP.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/116
• Priority: Minor

Tools: Error when running mbed test --compile/run list

• Description: The error, "pkg_resources.DistributionNotFound: The 'mbed-ls==1.*,>=1.5.1' distribution was not found and is required by icetea, mbed-flasher" is observed when running the command "mbed test -m K64F -t ARM --icetea --compile-list -vv".
• Workaround: None
• Reported Issues: https://github.com/ARMmbed/mbed-os/issues/8064
• Priority: Major

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

Using this release

You can fetch this release from the mbed-os GitHub repository, using the tag "mbed-os-6.9.0".

If you need any help with this release please visit our support page, which provides reference links and details of our support channels.

We are pleased to announce the Mbed OS 6.8.0 release is now available.

Summary

There is no major new functionality introduced as part of this release, but some of the enhancements we've made to extend BLE functionality have changed APIs, so as per semantic versioning, we've incremented the release version.

This release includes further changes for CMake support in Mbed OS and this now requires the mbed-tools version to be upgraded to 7.1.0 in order to function correctly.

The CMake changes are summarised below;

CMake: all Mbed OS targets contain CMakelists.txt
CMake: Post build hooks implemented (TF-M not yet supported)
CMake: CMake targets refactored to simplify custom targets creation

Migration Guide

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

BLE: Add APIs to get characteristic authorization callbacks.

14257

Summary of changes

This change adds two APIs to query the registered callbacks in a characteristic.

BLE: Add API to test the presence of an event handler in a chain.

14256

Summary of changes

Add a function to test if a handler is present in an event chain.

Update EventQueue API to use chrono times

13975

Summary of changes

Main dispatch function is updated to take a Chrono duration instead of an integer milliseconds parameter.
To allow for the instances of blocking and non wait versions, which previously were actioned by passing either -1 or 0 as the millisecond delay respectively, two other functions are now available.
dispatch_once() - new
dispatch_forever() - internally modified from the original version but no change in functionality
Note without this fix EventQueue dispatch function is actually broken. Events may not be dispatched at all or in the worst case the chip will crash.

Impact of changes

This is an API change, affecting the following areas:

• The parameter passed to the EventQueue.dispatch() function will now need to be a Chrono duration.
  E.g. '100ms'
• The dispatch_forever() function has been changed internally but the API itself remains the same.
• A new function, dispatch_once() has been added.

Migration actions required

The following migrations actions are required:

• Calls to EventQueue.dispatch(int ms) will now need to be changed to use EventQueue.dispatch(chrono wait). This should be
  as simple as adding 'ms' to any passed literal value. E.g. '100' becomes '100ms'. Variables passed in will need to be explicitly
  converted.
• Calls to EventQueue.dispatch(-1) should used EventQueue.dispatch_forever()
• Calls to EventQueue.dispatch(0) should used EventQueue.dispatch_once()

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.

Summary

There is no major new functionality introduced as part of this release, but some of the enhancements we've made to existing functionality have changed APIs, so as per semantic versioning, we've incremented the release version.

The full details are below but in summary we've introduced the following changes;

• Further evolved the Mbed CLI 2 tools by adding support to build greentea tests using CMake
• Added the Arduino Portenta H7 as a supported target
• Add support for the ST Microelectronis BlueNRG_2 BLE Component

Migration Guide

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

CMake: Add Support for hal greentea test

14093

Update events period method to check for invalid values

14087

Summary of changes

The period method currently allows any ms value:
positive, negative and zero.
A negative value means dispatch a non periodic event. ie just once.
0 is unspecified behaviour.
This commit forces the user to use either positive periods or a new constant, non_periodic
and should any other value be provided will default to non_periodic.
A Greentea test case is also provided to check this works as
expected.
I'm classifying this as a feature change rather than major because allowing a zero value was actually a bug.

Impact of changes

If the user provides a 0 value this will now behave differently. Previously it would have run for a period of
time as if this was an indefinite event before eventually (with a timer wrap) have unspecified behaviour.
Now the event period will default instead to non periodic.
To specify a non periodic event a user could previously use any negative value. Whilst this will still work (due a default
being set on invalid values), the user is encouraged to use the new constant, 'non_periodic' to show that this is what was
intended.

Migration actions required

Use periods that are > 0ms or non_periodic constant.

CMake: Add CMake to platform greentea test

14072

Summary of changes

• Added CMakeLists.txt file to every test suite under the platform so that it can build via CMake command
• Added the CMake Macro mbed_greentea_cmake_macro with configurable arguments TEST_NAME, TEST_INCLUDE_DIRS, TEST_SOURCES, TEST_REQUIRED_LIBS so that it can be used across all the greentea test suite by passing their includes, sources required libraries.
• Added CMake macro MBED_BAREMETAL_GREENTEA_TEST which can ON/OFF via CMake command-line argument at the configuration time to select/unselect baremetal greentea test

CMake: Create mbed-greentea library

14061

Summary of changes

The greentea framework provides all the infrastructure for the test suite to execute in the target like greentea-client, unity, utest so created the mbed-greentea interface library which binds all these framework sources, and all the test suite needs to add mbed-greentea lib into their target_link_library

CMake: Add CMake to drivers greentea test

14060

Summary of changes

• Added CMakeLists.txt file to every test suite under the mbed_drivers so that it can build via CMake command

Add std::span implementation for cxxsupport

13881

Summary of changes

Adds std::span implementation to cxxsupport folder in namespace mstd.
See discussion in https://github.com/ARMmbed/mbed-os/pull/13868.

Add Arduino Portenta H7 as target

13826

Summary of changes

This PR series introduces the support for Arduino Portenta H7 .
The patchset has been split into independent PRs for an easier review.

Impact of changes

Except the standalone TARGET_PORTENTA* content, some other files have been touched (all of them in separate commits).
In particular, COMPONENT_WHD has been made generic (any mbed target implementing SERIAL_FC can now compile it) but this could impact PSOC6 targets which used to configure it via Cypress HAL.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/116
• Priority: Minor

Tools: Error when running mbed test --compile/run list

• Description: The error, "pkg_resources.DistributionNotFound: The 'mbed-ls==1.*,>=1.5.1' distribution was not found and is required by icetea, mbed-flasher" is observed when running the command "mbed test -m K64F -t ARM --icetea --compile-list -vv".
• Workaround: None
• Reported Issues: https://github.com/ARMmbed/mbed-os/issues/8064
• Priority: Major

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

We are pleased to announce the Mbed OS 6.6.0 release is now available.

Summary

There is no major new functionality introduced as part of this release, but some of the enhancements we've made to existing functionality have changed APIs, so as per semantic versioning, we've incremented the release version.

The full details are below but in summary we've introduced the following changes;

• BLE update to the GATT API to better reflect what the specification define
• Add a method to allow an application to set or get the MAC address for Wi-SUN
• Restructuring of KVStore to better support the bare metal profile
• Enhancements to printing floating point values
• Improved memory and performance for ticker support

Migration Guide

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

Update GattAuthCallbackReply_t enumeration.

14014

Summary of changes

Add missing values that are present in pal::AttErrorResponse.
This allows applications to use correct ATT error codes.
The values have been changed to reflect what is actually defined in the specification. The 0x01 was a leftover from softdevice's days.

Network interface MAC address set/get

13936

Summary of changes

Add method set_mac_address that Application can use to set MAC address to the interface.
Update get_mac_address to return MAC address correctly from EMAC.
This PR is copied from: #13902

Restructure KVStore to one library per store type

13908

Summary of changes

Fixes: #13657
Mutually depends on: https://github.com/ARMmbed/mbed-os-example-kvstore/pull/60
In #13307 we combined multiple KVStore types (TDBStore, FileSystemStore) and the global API into one library, kv-global-api. This is inconvenient for users of bare metal: if they only want one store type, they need to add dependencies for other unused types and the global API to "requires". This becomes cumbersome as FileSystem has many dependencies.
This PR restructures KVStore to follow the same logic of BlockDevice: declare the interface at the top level, and treat each type/implementation as a "sub-" library. Users only need to enable the interface + the type they need. So each of the following is a library (containing mbed_lib.json):

• storage/kvstore: KVStore interface
• storage/kvstore/tdbstore: TDBStore : KVStore class
• storage/kvstore/filesystemstore: FileSystemStore : KVStore class
• storage/kvstore/securestore: SecureStore : KVStore class
• storage/kvstore/kvstore_global_api: optional API to globally manage instances of KVStore, containing kvstore_global_api functions and KVMap which is a helper class for the global API
• storage/kvstore/kvconfig: configurations
  Greentea and unit tests have also been moved into subdirectories of corresponding KVStore types.
  Note: The CMake support for KVStore has not been componentised yet - compilation with CMake still brings in all the unused types and dependencies, because everything is under one mbed-storage-kvstore target. Hopefully the CMake team will later componentise each type of KVStore into mbed-storage-kvstore-<type>. similar to what they've already done for BlockDevices. @0xc0170 (Update: required CMake changed included in this PR)

Impact of changes

Users can enable one type of KVStore (e.g. TDBStore) without having to bring in dependencies for unused types of KVStore.

Migration actions required

For a bare metal application, add "kvstore" and the type of KVStore to use (e.g. "tdbstore") to "requires" in mbed_app.json. Note that the KVStore interface library is "kvstore", not "kv-global-api" which now contains only the global API.
To use CMake (full profile and bare metal profile): Add the TDBStore sub-component you need (e.g. mbed-storage-tdbstore) and dependencies (e.g. TDBStore requires mbed-storage-blockdevice) to your app's CMakeLists.txt.

Add width modifier and prepending zeros for hexadecimal output and decimal precision for floating point

13548

Summary of changes

Added width modifier and prepend zeros if the width modifier is given feature to printing integer, hexadecimal and floating point values. So e.g. printf("%04X", i); works now the same as the std version.
Added precision specifier for printing floating point values, as it already existed for strings. If no precision specifier is given MBED_CONF_PLATFORM_MINIMAL_PRINTF_SET_FLOATING_POINT_MAX_DECIMALS will be used.
This PR also fixes #13783.

Impact of changes

Prepending zeros and width modifier work with integer, hexadecimal and floating point values when using minimal_printf.
Also the precision modifier works for floating point variables. If no precision specifier is given MBED_CONF_PLATFORM_MINIMAL_PRINTF_SET_FLOATING_POINT_MAX_DECIMALS is used.

Optimise mbed_ticker_api.c

12897

Summary of changes

The generic code in mbed_ticker_api.c uses run-time polymorphism to handle different tickers, and has generic run-time calculations for different ticker widths and frequencies, with a single special-case for 1MHz.
Extend the run-time special casing to handle any conversion cases where either the multiply or divide can be done as a shift. This is a speed optimisation for certain platforms.
Add a new option target.custom-tickers. If turned off, it promises that only USTICKER and LPTICKER devices will be used. This then permits elimination and/or simplification of runtime calculations, saving size and speed. If either both USTICKER and LPTICKER have the same width, or the same period numerator or denominator, or only one of them exists, then operations can be hard-coded. This is a significant ROM space saving, and a minor speed and RAM saving.
We get to optimise all the calculations, but the run-time polymorphism is retained even if there is only one ticker, as it doesn't significantly affect code size versus direct calls, and the existence of
lp_ticker_wrapper and various us_ticker optimisations requires it, even if only LPTICKER is available.

Impact of changes

• Targets should make an effort to define the new LP_TICKER_XXX defines to help the optimisation kick in.

Migration actions required

None

Using this release

You can fetch this release from the mbed-os GitHub repository, using the tag "mbed-os-6.6.0".

If you need any help with this release please visit our support page, which provides reference links and details of our support channels.

We are pleased to announce the Mbed OS 6.5.0 release is now available.

Summary

The Mbed team are delighted to introduce the foundations of our new command line build tools, which use CMake to configure the build artifacts and, we hope, significantly improve the build experience for Mbed developers. These tools are still being refined and developed, but the basics are now available and will co-exist alongside the existing Mbed CLI tools for the time being. We'd really appreciate feedback from Mbed users on these tools as we want to ensure Mbed developers are seeing value in them.

The new tools can be found here .

We've also added some changes to how the Cordio BLE stack is configured to work with Nordic targets.

Migration Guide

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

Update NRF ble configuration options

13910

Summary of changes

This allows for changes to the buffers allocated in NRFCordioHCIDriver.cpp. Since the amount of buffers can be configured using the mbed_app.json it is only natural to also configure the buffer sizes that go with the number of buffers.
I also removed the confusing configuration settings used only by the NRF52840 which overruled other settings made by the cordio-ll config.

Impact of changes

No functionality change, only configuration changes

Migration actions required

All the default settings remained the same and if no custom configuration is used in mbed_app.json the no actions are required.
If you use the NRF52840 and have overruled any of the following settings you may need to change:

• "cordio-ll-nrf52840.phy-coded-support" into "cordio-ll.phy-coded-support"
• "cordio-ll-nrf52840.extended-advertising-size" into "cordio-ll.extended-advertising-size"
• "cordio-ll-nrf52840.max-acl-size" into "cordio-ll.max-acl-size"
• "cordio-ll-nrf52840.tx-buffers" into "cordio-ll.tx-buffers"

CMake: Add initial support

13566

Summary of changes

Addition of CMake modules and input source files to configure the project and generate the scripts needed by the build systems (tested with Unix Makefiles and Ninja) to build Mbed OS as a library. Mbed OS is built as collection of all libraries supported by a given target.
There are two main targets: mbed-os and mbed-baremetal. The rest of the components in the Mbed OS repository are targets prefixed with mbed-, for example mbed-ble and mbed-netsockets.
Even though this is still under development. This PR was raised as the current state does not affect builds of the OS with the traditional tools (Mbed CLI, Online compiler, Mbed Studio).
For current state of development, supported targets, supported toolchains, known issues, and build steps, see "Documentations" section below.

Impact of changes

Adding/removing source files or subdirectories requires adding or updating CMake input source files as all source files are listed in them.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/116
• Priority: Minor

Tools: Error when running mbed test --compile/run list

• Description: The error, "pkg_resources.DistributionNotFound: The 'mbed-ls==1.*,>=1.5.1' distribution was not found and is required by icetea, mbed-flasher" is observed when running the command "mbed test -m K64F -t ARM --icetea --compile-list -vv".
• Workaround: None
• Reported Issues: https://github.com/ARMmbed/mbed-os/issues/8064
• Priority: Major

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

• Mapped MBED_CONF_MBED_CLIENT_RECONNECTION_COUNT Pelion Device Management Client configuration option to SN_COAP_RESENDING_MAX_COUNT in mbed-coap.
• Fix the token from blockwise ACK message to be empty if the received message doesn't have one.

Fix for linker issue in AdBun-M066

13578

Summary of changes

Linker issue:
The hardcoded __initial_sp from the startup file of AdBun-M066 (startup_TMPM066.S) has been removed.
The initial stack pointer value ARM_LIB_STACK has been imported from the scatter file of AdBun-M066 (tmpm066fwug.sct).
As per scatter file of AdBun-M066,
initial stack pointer = 0x200000C0 + 0x4000 : 0x200040C0 (which is beyond the RAM of AdBun-M066)
So, Stack pointer must be initialized to =
RAM starting address + Size of RAM = 0x20000000 + 0x4000 (16KB)

mbed-os-5.15: Add external RADIUS server configuration to Wi-SUN Border Router

13576

Summary of changes

Added configuration functions and .json configuration options for:

• external RADIUS server IPv6 address
• RADIUS shared secret.
• RADIUS client retry trickle timer configuration. This can be used to set how fast
  the RADIUS client retries Access-Request messages to RADIUS server in case reply
  from server is not received.
  This combines following RADIUS configuration pull requests from feature-wisun:
  https://github.com/ARMmbed/mbed-os/pull/13412

  These same changes are available in feature-wisun branch in PR: #13550

Nuvoton: Fix degrading QSPI to SPI (5.15)

13537

Summary of changes

Same as #13536 but backport to mbed-os 5.15, this PR tries to fix logic with degrading QSPI to SPI. In most cases, we can control degraded QSPI H/W to standard through BSP SPI driver directly as if it is just SPI H/W. However, BSP SPI driver distinguishes among SPI H/W instances in functions:

• SPI_Open
• SPI_Close
• SPI_SetBusClock
• SPI_GetBusClock
  In these cases, we must change to QSPI version instead for QSPI H/W.

device_management.py supports application access keys 5.15

13525

Summary of changes

The Mbed CLI tool fails to initialize with application access keys. This PR changes the device_management.py so that it works with the new access keys as the legacy API key feature is now deprecated in Pelion Device Management.

Impact of changes

The init script still works with legacy API keys.

Summary

This release contains significant changes to how Mbed supports BLE privacy, addressing issues some users may have seen when pairing a device running Mbed with either Android or iOS.

We've also updated the Mbed COAP implementation to v5.1.8.

Finally, we've made some further improvements to the WiSUN stack to address issues raised by both internal and external testing.

BLE: Introduce ChainableEventHandler and subclasses

13734

Summary of changes

Requires #13727 to be merged first
Merged #13727 since this PR is closely tied to it.
Introduces a ChainableEventHandler base class that is essentially a singly-linked-list of EventHandlers along with two subclasses:

• ChainableGattServerEventHandler that enables chaining together GattServer::EventHandlers
• ChainableGapEventHandler that enables chaining together Gap::EventHandlerss
  The ChainableGattServerEventHandler class allows an application to register separate event handlers (eg: for different services that need to handle GattServer events) and then set the global GattServer::setEventHandler to the instance of ChainableGattServerEventHandler with all registered GattServer::EventHandlers.
  The ChainableGapEventHandler accomplishes that same as above for Gap:EventHandler implementations.
  Common functionality has been split off into ChainableEventHandler.
  See #13728 for discussion around this implementation.

Feature ble host privacy

13717

Summary of changes

This PR reimplements Bluetooth privacy for all type of Bluetooth controllers (4.0 to 5.2).
As soon as privacy is enabled, a private address is used to advertise, scan or initiate connection and peers resolvable addresses are resolved if a bond with matching IRK is found in the security database.
This should solve most of the pairing issues observed on Android and iOS where the local device is not able to retrieve a previous bond.
Internally there is two implementations of the address resolution:

• Host based where the software compute if the address is known or not
• Controller based where the Bluetooth controller resolves automatically addresses received during advertising or scan.
  New configurations flags have been added to select at compile time the implementation to use:
• ble-gap-host-based-private-address-resolution Forces the system to use host based resolution
• ble-gap-host-privacy-resolved-cache-size Indicate how many entries must be booked for the host based resolution cache.
  This PR is the result of the following PRs merged on the feature branch
• Privacy feature configuration: https://github.com/ARMmbed/mbed-os/pull/13662
• Force device mode for LL resolution: https://github.com/ARMmbed/mbed-os/pull/13689
• Privacy enable event emission : https://github.com/ARMmbed/mbed-os/pull/13680
• Improvement of Secure DB entry retrieval: https://github.com/ARMmbed/mbed-os/pull/13660 and https://github.com/ARMmbed/mbed-os/pull/13658
• Force identity address to be static: https://github.com/ARMmbed/mbed-os/pull/13622
• Local private address management: https://github.com/ARMmbed/mbed-os/pull/13582 and https://github.com/ARMmbed/mbed-os/pull/13560
• Peer private address management: https://github.com/ARMmbed/mbed-os/pull/13630 and https://github.com/ARMmbed/mbed-os/pull/13685:
• Fixes: https://github.com/ARMmbed/mbed-os/pull/13656 and https://github.com/ARMmbed/mbed-os/pull/13670
• Notification when advertising start or stop: https://github.com/ARMmbed/mbed-os/pull/13706

Impact of changes

Existing applications should not have anything to change regards to calls to privacy APIs as this PR enables it for all type of controllers and not just resolution when supported by the hardware.
The advertising state was showing up as enabled as soon as the function startAdvertising was called. This is was not correct as it wasn't reflecting the reality of operations. The state is now modified when advertising is actually active. Two new events have been added to Gap::EventHandler to catch the change of advertising state.

Add mutiple push and pop for circular buffer

13563

Summary of changes

Add functions to circular buffer to allow pushing and popping multiple items at a time.

Add OSPI driver to support the Octa mode of Macronix octaflash MX25LM51245G

12644

Summary of changes

Update PR #12619.
Add OSPI HAL driver and OSPIF block device driver for using Macronix octaflash MX25LM51245G.
ST Octo-SPI was ported on QSPI MBED API, but we can only use in SPI mode and the Octo mode is not supported. So, we add OSPI driver to enable Octo mode to improve read and write performance.

Impact of changes

Enable the octa mode of MX25LM51245G.

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: https://github.com/MicrochipTech/cryptoauthlib/issues/116
• Priority: Minor

Tools: Error when running mbed test --compile/run list

• Description: The error, "pkg_resources.DistributionNotFound: The 'mbed-ls==1.*,>=1.5.1' distribution was not found and is required by icetea, mbed-flasher" is observed when running the command "mbed test -m K64F -t ARM --icetea --compile-list -vv".
• Workaround: None
• Reported Issues: https://github.com/ARMmbed/mbed-os/issues/8064
• Priority: Major

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

In mbed OS 6.3.0, the compilation test targets scope has not changed and remains all mbed OS enabled targets.

Greentea test targets have been changed slightly:

At the time of the mbed-os 6.3.0 release, we run the greentea tests on the following 8 targets:

• NRF52840_DK
• DISCO_L457VG_IOT01A
• K64F
• K66F
• NUCLEO_F411RE
• NUCLEO_F429ZI
