mbed-os-6.2.0

We are pleased to announce the Mbed OS 6.2.0 release is now available.

Summary

This release mainly provides updates for some of the connectivity protocols that Mbed OS supports, specifically BLE and WiSUN.

For BLE, we've updated the Cordio stack to version 20.05, which is the latest 5.2 specification qualified version. We've also made some changes to the BLE Security Manager to better support the handling of identity addresses when privacy is enabled.

For Wi-SUN, we've made API updates to the border router support we offer for Wi-SUN networks. A border router is a network gateway between a wireless 6LoWPAN mesh network and a backhaul network. It controls and relays traffic between the two networks and, in this release, we've added additional APIs to allow developers to access routing table data from border routers.

The other major change is to upgrade the version of the Arm Compiler to the latest 6.14 version as part of our commitment to track the latest stable versions of the compilers we support.

Migration Guide

This section lists specific changes which are part of this release and may

BLE: Add KVStore Security DB

13038

Summary of changes

This adds a new Security DB type for BLE Security Manager. This is optional and disabled by default. The presence of filesystem and kvstore DBs is now set in the mbed_lib.json file with the default values retaining the current setup.
Requires preceding PR: #13037
(so ignore the first commit)

Always build both .hex and .bin files

13011

Summary of changes

• This change will cause build-system to produce both .bin and .hex files.
• Files are small and their creation is fast, thus there are no negative impact
  on build time and storage requirements.
• .bin files are required for updating the device
• .hex files are very handy for post build (external to build system) custom
  scripts (e.g. image signing)
• Configuration still allows selecting either .bin or .hex files, this settings is still
  relevant as it specifies what file is flashed to a device for tests or by
  --flash argument.

Impact of changes

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

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: #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

Summary

The major feature we introduce in this release aims to improve your experience with Arm’s Platform Security Architecture when used in conjunction with Mbed OS. Platform Security Architecture, or PSA, is an Arm- led framework for securing IoT devices. In Mbed OS we support PSA in conjunction with the TF-M (www.trustedfirmware.org) project, and we have made major changes in how we integrate TF-M into Mbed in this release, with the overall goal of simplifying how Mbed users consume it. The main change is that we now support building the Secure side binary directly, using the latest supported TF-M version for the target and linking that into the Mbed build.

We are working with our silicon partners to assist them in migrating their PSA platforms to support this change,

Remove Musca A1 target

13165

Summary of changes

The Musca A1 target hasn't been Mbed Enabled nor considered supported in 6.0.
Although support exists in Mbed OS 5.15 and 6.0, it is not officially supported and hence removed.However, it continues to be available in 5.15.

Impact of changes

NA - continues to be available in the mbed-os-5.15 branch.

Migration actions required

Switch to the mbed-os-5.15 branch.

Cellular: ALT1250: Store RAT to permament memory

13149

Summary of changes

Save RAT selection to modem's permanent memory.

Impact of changes

This avoid unnecessary changing of RAT on every reboot if it is different than the default saved in modem's permanent memory.

M2351: Remove from master

13148

Summary of changes

Since Mbed OS 6.0, secure build is not supported yet. Remove it from master temporarily.
For non-TF-M support (NU_PFM_M2351_NPSA_S/NS), go to mbed-os-5.15 branch and Mbed OS 5.15 release.
For TF-M support (NU_PFM_M2351_S/NS), this needs M2351 integrated into TF-M repo first.
Expect M2351 TF-M support can come back into master after integration with TF-M is finished.

Impact of changes

M2351 non-TF-M targets NU_PFM_M2351_NPSA_S/NS are removed from Mbed OS 6.0. Its support is kept on Mbed OS 5.15.

13142

Summary of changes

Fixed the Chrono compilation warning in EMAC drivers by using Chrono based time argument in EventQueue call_every() API call.

Impact of changes

With these changes, no more compilation warning get reported during the build.

Cypress: us_ticker fixes

13130

Summary of changes

• Explicitly disable the timer used for the us_ticker before attempting to enter DeepSleep.
  A running timer will block DeepSleep, which would normally be good because we don't want the timer to accidentally lose counts. We don't care about that for us_ticker (If we're requesting deepsleep the upper layers already determined that they are okay with that), so explicitly stop the us_ticker timer before we go to sleep and start it back up afterwards.
• Add optional post-bsp-init hook
  This allows the application to inject its own resource reservations immmediately after the BSP (and therefore HAL) is initialized, ensuring that they can claim require resources before mbed tries to use them for more flexible purposes. For example, the application might want to claim a particular timer to make sure that it doesn't get picked for us_ticker (which can use any arbitrary timer instance).

Cypress: Add target CY8CKIT_064B0S2_4343W, update psoc6pdl, psoc6cm0p

13122

Summary of changes

This is final PR to add Cypress new secure boot target CY8CKIT_064B0S2_4343W to mbed-os.
This PR also includes update of psoc6pdl and psoc6cm0p libraries for Cypress targets.

Impact of changes

• Target CY8CKIT_064B0S2_4343W BSP code will be added
• psoc6pdl will be updated - impacts all Cypress targets
• CY8CKIT_064S2_4343W, CY8CPROTO_064_SB, CYESKIT_064B0S2_4343W will be removed as obsolete due to production release of PSOC64 chips and thus new Secure Boot flow, represented in this PR
• Secure Boot post build scripts will be substituted to new implementation for this and all following Secure Boot targets
• psoc6cm0p will be updated - impacts all Cypress targets
  All existing Cypress targets BSP will switched to new versions assets in next PRs.

Migration actions required

Configuration of mbed-os CI need to be updated per new post build hooks.

• CY8CKIT_064S2_4343W, CY8CPROTO_064_SB, CYESKIT_064B0S2_4343W will be removed as obsolete due to production release of PSOC64 chips and thus new Secure Boot flow, represented in this PR.
  New release of mbed-os 6.0 will no longer support targets above, updated PSOC64 targets instead will be added to support new tools.

Fix BOOT_HEADER_SIZE allocation in ARM scatter files (#13058)

13100

Summary of changes

PSoC 64 secure BSP post-build hook (cysecuretools image signing)
expects the HEX file with start address 0x10000400 (first KB of
internal FLASH is reserved for MCUboot headers area).
In order to get the correct HEX file produced by ARM fromELF tool,
the ELF file should allocate LR_IROM1 starting from address
0x10000400, not 0x10000000. Otherwise the generated HEX file
allocates rows at addresses 0x10000000 ~ 010000400 and the
final application image is not signed correctly.
Fixes #13058.

Impact of changes

Fix TARGET_CY8CPROTO_064_SB and TARGET_CYESKIT_064B0S2_4343W signed HEX image generation with TOOLCHAIN=ARM.

Summary of changes

Nanostack release v12.3.0 to master branch
Nanostack v12.3.0 contains bug fixes and stability improvements to the Wi-SUN protocol stack.
802.15.4 RF drivers has been updated to match functionality in Nanostack v12.3.0.
This is upstream of PR: #13079

Impact of changes

Wi-SUN protocol stack is more stable and is scaling to larger number of devices.
Mesh applications that are using Wi-SUN protocol can define S2LP RF driver PIN configuration in the application configuration file.

Python reference equality changed to value equality

13077

Summary of changes

In tools/config/__init__.py a reference comparison (is) was used to compare a variable with a string literal, but a value comparison (==) should be used instead.
This shows up as a python warning during compilation. Python documentation is here for the obsolete Python 2.7, the minimum supported version (by the Python foundation) 3.5, and the latest 3.9.

Impact of changes

This will remove the warning emitted during compilation with the cli (and probably elsewhere).
This should fix any potential issues if cpython and friends decide to change how string caching works.

mbed-os-6.0.0

We are pleased to announce the Mbed OS 6.0.0 release is now available.

Summary

The Arm Mbed team is delighted to announce the release of Mbed OS 6, our first major release in almost four years. We have invested heavily to add the features required for today’s IoT devices, and to back those features up with state of the art tooling to simplify development of IoT and embedded products.

This release includes:

• Stable and mature APIs, alongside the introduction of the 'Experimental' tag to indicate new APIs that are subject to change.
• Board support for the most popular boards.
• The ability to support custom hardware.
• The option of adding a community supported board.
• Further enhancements to the Bare Metal Profile.
• Integration with the AWS SDK, with other major cloud integrations to follow.

There have also been some significant changes to our BLE offering, as summarised below.

BLE changes

#12674, #12676, #12742, #12730

We have removed all deprecated APIs in BLE and adjusted other APIs to resolve dependencies on the deprecated ones. We have also removed target-specific stacks that are incompatible with the latest APIs.

Item	Change	Migration
SoftDevice stack	Superseded/Removed	* For nRF52* targets, please use the Cordio stack, which is already enabled by default. * nRF51* targets will be unsupported in future Mbed OS releases.
Maxim stack	Removed	BLE feature on Maxim targets is disabled until an updated version becomes available.
Non-SIG services based on third-party standard: DFUService UARTService EddystoneConfigService EddystoneService URIBeaconConfigService iBeacon	Removed	If needed, you can take services from Mbed OS 5.15 and update the code, or implement your own based on specifications.
Legacy APIs in BLE.h	Superseded	See functions marked with MBED_DEPRECATED() in Mbed OS 5.15's BLE.h for migration advice in comments.
Legacy APIs in GattCharacteristic.h	Superseded	See functions marked with MBED_DEPRECATED_SINCE() in Mbed OS 5.15's GattCharacteristic.h for migration advice in comments.
Legacy APIs in GattClient.h	Superseded	See functions marked with MBED_DEPRECATED() in Mbed OS 5.15's GattClient.h for migration advice in comments.
Legacy APIs in SecurityManager.h	Superseded	See functions marked with @deprecated in Mbed OS 5.15's SecurityManager.h. Applications should implement the SecurityManager::EventHandler interface and register it with SecurityManager::setSecurityManagerEventHandler(...).
Legacy APIs in Gap.h	Superseded	See functions marked with MBED_DEPRECATED_SINCE() in Mbed OS 5.15's Gap.h for migration advice in comments.
Gap::getMinAdvertisingInterval() Gap::getMinNonConnectableAdvertisingInterval() Gap::getMaxAdvertisingInterval()	Removed	The values are constant and target-agnostic. Use ble::adv_interval_t::min() and ble::adv_interval_t::max().
Gap::getDeviceName() Gap::getAppearance()	Removed	Device Name and Appearance are set by the application, which should already know the values.
Gap::setDeviceName() Gap::setAppearance()	Superceded	Use AdvertisingDataBuilder to add Device Name and Appearance to the payload, then apply the payload with Gap::setAdvertisingPayload().
Gap::getPreferredConnectionParams() Gap::setPreferredConnectionParams()	Removed (temporarily)	We plan to move them to GattServer in the future.
BLEProtocol::AddressType_t BLEProtocol::AddressBytes_t	Superseded	Replaced by ble::peer_address_type_t ble::own_address_type_t ble::address_t To decide which ones to use, see the functions you want to call.
Gap::Whitelist_t BLEProtocol::Address_t	Changed	Replaced by ble::whitelist_t where each item on a whitelist is ble::whitelist_t::entry_t. This is used by Gap::setWhitelist() SecurityManager::generateWhitelistFromBondTable().
Gap::ConnectionParams_t	Superseded	The latest GAP API requires full-fleged ble::ConnectionParameters.
ble::central_privay_configuration_t	Typo fixed	Renamed to ble::central_privacy_configuration_t.

Supported compilers

This release has been tested and is known to fully support the following compilers:

• ARMC v6.13
• GCC v9

Other versions of the compilers may not work as expected.

Migration Guide

This section lists specific changes in this release that may need special attention.

DeviceKey Root of Trust generation refactored

12385

Summary of changes

Removed automatic creation of the Root of Trust when DeviceKey::generate_derived_key(...) API is used.
You must generate or inject the key before the first use of the DeviceKey API.

Impact of changes

DeviceKey is not automatically generated anymore. This might impact test application that expect the key to be present, but do not explicitly generate it.

Migration actions required

Application developers must be aware that if their device does not have Root of Trust permanently injected, which is usually true in the development phase, they must generate a key before the first use of the DeviceKey API. Two options exist for key generation:

• Generate a key using TRNG sources by calling DeviceKey::device_generate_root_of_trust()
• If the device does not have a TRNG available, inject a secure key by calling DeviceKey::device_inject_root_of_trust(...)

Cellular: Move string_to_pdp_type method to CellularContext

12214

Summary of changes

string_to_pdp_type is only used in CellularContext classes, and having the conversion method in CellularContext means it can also be used to check the non-standard Non-IP PDP type string.

Impact of changes

None, if the application uses existing cellular classes. If you have implemented your own CellularContext class, then see Migration actions required below.

Migration actions required

Classes deriving from CellularContext must implement a new function:

virtual const char *get_nonip_context_type_str() = 0;

This API has already been implemented in AT_CellularContext though, so the current code does not change.

Blockdevice config changes to make it possible to run littlefs filesystem tests

12143

Summary of changes

Moves BlockDevice configurations used by SystemStorage as BlockDevice defaults. This makes it possible to use the defaults to execute littlefs filesystem tests.

Adds SPIF/QSPIF/SPIFReduced- and SDBlockDevice specific app configs for making it possible to run the aforementioned tests.

Thread: remove constructors deprecated in 5.1

12141

Summary of changes

Remove the immediate-start constructors deprecated in Mbed OS 5.1.

Impact of changes

Code using the old constructors will no longer compile.

Migration actions required

Code using immediate-start Thread constructors must be changed to use the Thread::start method.

Remove unsupported folder

12128

Summary of changes

Mbed OS has been carrying the unsupported directory for a long time, to give users a form of USB stack. This is no longer needed, since Mbed OS has its own implementation of USB.

Impact of changes

As the name suggest the 'unsupported' directory was not supported, but as it was there the community was free to use any of the functionality in it. So in theory it is a breaking change, even if the code was never properly supported.

Migration actions required

Removed functionality was never supported and its use was not recommended. If you used USB device mode, please port your code to use the supported version from the Drivers directory. If you need any other features please consider contributing them to Mbed.

Cellular: Refactor cellular variable visibilities

12123

Summary of changes

Cellular: Refactor cellular variable visibilities:

• Some variables were public despite being used only internally.
• Refactored variables to the end of class definitions.
• Removed duplicate _property_array from CellularDevice
• Changed _impl methods to protected.

Impact of changes

This can potentially be a breaking change, but none of the existing Mbed OS cellular targets required any changes.

Migration actions required

If you want to use a cellular variable marked as private, inform @ARMmbed/mbed-os-wan and we can review the case.

ATHandler refactoring

12122

Summary of changes

• ATHandler is part of Cellular's public API, so we moved it to the /API folder.
• Some functions and variables are refactored to be private/protected where applicable.
• Virtual cmd_start() (and destructor) method(s) devirtualised because it was not needed.
• Unittests updated to reflect changes.

Impact of changes

• ATHandler is part of Cellular's public API, so we moved it to the /API folder.
• Some functions and variables are refactored to be private/protected where applicable.
• Virtual `cmd_start(...

mbed-os-6.0.0-beta-1

We are pleased to announce the Mbed OS 6.0.0-beta-1 release is now available.

Summary

This is the last pre-release before we make the full 6.0.0 release. It contains the remainder of the breaking changes and any other significant updates.

Migration Guide

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

Correct Timeout rescheduling

12941

Summary of changes

Chrono changes "optimised" Timeout::handler in a way that broke users who rescheduled the timeout during their attached callback.

Attempted optimisation is less necessary now that platform.callback-nontrivial is set to false by default - that setting reduces overhead of copying the Callback to almost nothing.

Fixes #12940.

Correct core RTOS sleep routine timing

12938

Summary of changes

Chrono conversions inadvertantly changed the core timed sleep routine used by the RTOS idle to use OsTimer::update_and_get_tick() instead of OsTimer::get_tick().

Correct this, and expand/clarify documentation and naming to try to prevent recurrence.

Another minor fix observed while inspecting code - OsClock can't just use milliseconds, it should match the period of OsTimer, which theoretically can be different.

Fixes #12920.

Remove unsupported targets

12935

Summary of changes

This is another of a series of PRs (others #12775, #12810, #12864) to remove targets that are not supported or retired as explained in recent blog post.

"\r\n" by "\n".

Impact of changes

Breaks compatibility with applications built with Mbed 2.

Migration actions required

Update to the latest version of Mbed OS (possibly using the bare metal profile for ultra-constrained devices).

Bare metal profile: USB class device support

12873

Summary of changes

USBCDC_ECM class device uses RTOS thread APIs, so added MBED_CONF_RTOS_PRESENT conditional check to disable that class device in bare metal profile.

Impact of changes

Allow Devicekey::generate_root_of_trust() to define key size.

12823

Summary of changes

Allow Devicekey::generate_root_of_trust() to define key size.

By default, generate 16 byte keys, to be compatible with bootloader.
But allow user to generate 32 byte keys as well.

This fixes #12821

Impact of changes

Default key, generated by Devicekey::generate_root_of_trust() is now 16 bytes,
instead of 32 bytes.

Migration actions required

If you want to generate 32 byte keys with Devicekey::generate_root_of_trust(),
you need to explicitly supply key size as a parameter.

Migration Guide

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

Upgrade to Mbed TLS 2.21.0 and Mbed Crypto 3.1.0

12767

Summary of changes

Upgrade to Mbed TLS 2.21.0 and Mbed Crypto 3.1.0

Impact of changes

• Security fix for https://nvd.nist.gov/vuln/detail/CVE-2019-18222, without dropping Mbed TLS features by reverting back to an older LTS version of Mbed TLS (2.16.x). This requires bumping the version of Mbed Crypto to 3.1.0, which brings along with it an API break in the experimental PSA APIs

Migration actions required

What behavior changes are being made?
For security and NIST SP 800-90A compliance reasons, CTR DRBG now grabs a nonce from the entropy source if needed to provide the maximum security strength. A previously unused-before-seeding member of the CTR DRBG context, mbedtls_ctr_drbg_context::reseed_counter, is used to hold the number of bytes the user has requested to include from the nonce via mbedtls_ctr_drbg_set_nonce_len(), or -1 to indicate that the entropy nonce length was not set explicitly. This means applications that were depending on a reseed_counter value of 0 to mean "not yet seeded" will need to instead handle errors from calls to mbedtls_ctr_drbg_seed().

What is being deprecated?
A few PSA Crypto asymmetric cryptography functions and macros, key usage definitions, and error code definitions have been renamed to better reflect their operation and to improve readability.

Why is this being deprecated?
The PSA Crypto API continues to develop as it heads towards its 1.0 release. Mbed Crypto 3.0.0d0 implements more of PSA Crypto 1.0b3 than was implemented in Mbed Crypto 2.x, and this brings along some API deprecations.

Mbed Crypto includes backwards compatibility macros (by way of psa/crypto_compat.h) to provide source-level backwards compatibility, although it's recommended to stop using the deprecated APIs as soon as you are able to.

Migration
To avoid using deprecated APIs, users of PSA Crypto should update to the new version of API.
