mbed-os-6.0.0-alpha-2

We are pleased to announce the Mbed OS 6.0.0-alpha-2 release is now available.

Summary

This is the second preview of approaching Mbed OS 6.0 release. We continue our efforts to remove previously deprecated APIs and features. This release intentionally breaks compatibility both with Mbed OS 5 series and previous Mbed OS 6 preview. For details of breaking changes please have a look at the release notes below.

Migration Guide

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

Add an exception for ARMC5 toolchain build

12400

Summary of changes

The Arm Compiler 5 is no longer supported so removed the deprecate warning and added the exception in the build tool to stop building with ARM compiler 5.

Impact of changes

With these changes, Arm compiler 5 build fails

Migration actions required

Upgrade the enviroment to use Arm Compiler 6 refer

Remove CPU usage example from CI build

12335

Summary of changes

• Removed the CPU usage example from the Mbed OS build tool CI configuration as it's deprecated.

Impact of changes

With these changes, Mbed OS CI will no longer build CPU usage example on every PR check.

Ble driver set random static address

12321

Summary of changes

This PR adds the function set_random_address to the HCIDriver class. It allows drivers writer to set the Random Static Address of the controller without using the deprecated API Gap:: setAddress .

This PR supersede #12235 .

MXRT1050 Flash support

12317

Summary of changes

Add Flash support for MXRT1050

Cellular: Remove support for multiple ATHandlers

12305

Summary of changes

This commit removes multi ATHandler support from cellular. This has not been used and causes unnecessary complexity and memory consumption.

Memory statistics of mbed-os-example-cellular with NRF52840_DK + BG96:
GCC:
Total Static RAM memory (data + bss): 29360(+296) bytes
Total Flash memory (text + data): 130660(-832) bytes

ARM:
Total Static RAM memory (data + bss): 261554(+8) bytes
Total Flash memory (text + data): 127573(-1193) bytes

IAR:
Total Static RAM memory (data + bss): 25479(+296) bytes
Total Flash memory (text + data): 102418(-527) bytes

RAM increase is because now ATHandler is no longer created with new -operator but is now member of AT_CellularDevice, so image tool is able to count it. Actual total RAM consumption has decreased due to removed variables.

Impact of changes

Major changes:

• Dependency to FileHandle removed from base classes
• AT_CellularDevice owns the default FileHandle and shares it with AT -classes
• Controlling hang-up -detection moved as CellularContext::configure_hup(). Cannot be configured via CellularDevice any more.

Migration actions required

• Enabling hang-up detection is now configured using CellularContext::configure_hup(). CellularDevice::enable_hup() and context creation with BufferedSerial handle removed. Cellular will now automatically enable and disable HUP when switching between AT and PPP mode.
• CellularDevice::create_context() no longer takes FileHandle as parameter
• CellularDevice::get_file_handle() removed. ATHandler::get_file_handle() can be used instead.

MIMXRT1050: Add Watchdog support

12299

Summary of changes

Add WatchDog support for MXRT1050 EVK

Cellular: Remove API's empty default implemetations

12293

Summary of changes

Cleanup the Cellular API by removing empty default implementations and making them pure virtual.

Targeted for release-version 6.0.0.

Impact of changes

• Classes inheriting CellularDevice will have to have implementation for the new pure virtual methods:
• clear()
• get_context_list()
  
  
• Classes inheriting CellularContext do not have to have implementation for:
• get_netmask()
• get_gateway()

if they do not differ from the NetworkInterface's default implemetations:

nsapi_error_t NetworkInterface::get_netmask(SocketAddress *)
{
return NSAPI_ERROR_UNSUPPORTED;
}

nsapi_error_t NetworkInterface::get_gateway(SocketAddress *)
{
return NSAPI_ERROR_UNSUPPORTED;
}

Migration actions required

See Impact of changes section.

Rename "default_lib" to "c_lib".

12278

Summary of changes

• Rename target.default_lib to target.c_lib as it is more meaningful. These changes are done only for MBED OS 5 targets and in the build tool.

Impact of changes

With these changes, target.default_lib attribute is no longer being supported.

Migration actions required

• The target.c_lib is the new attribute used for C library selection. The choice remains unchanged("std" or "small")

unittests: disable coverage report filtering

12273

Summary of changes

Disable coverage report filtering because of poor results.

e.g. mbed test --unittests -r Socket --coverage htmlg
This command will run all unittests with names containing Socket and then create coverage report with the same scheme, filtering all source files with names containing Socket.

The problem is that coverage report will be correct only when filtered test name will be the same as corresponding source file name (to be covered) - the same (-r) pattern is used to filter both test names and source file names used in coverage report

Due to described problems it was decided to disable coverage report filtering.
-r will only filter test names and pattern won't be passed to coverage report generator.

Add KSZ8041 as a supported PHY for the LPC17xx series

12260

Summary of changes

Adds the Microchip KSZ8041 PHY as a supported device for the LPC17xx series.

storage_abstraction: deprecated since Mbed OS 5.5 and now removed

12253

Summary of changes

Removes deprecated API's under hal/storage_abstraction and the folder itself. Only target which had implemented the functionality was K64F and the implementation gets removed with this PR.

Impact of changes

Removes deprecated storage_abstraction API.

Migration actions required

Migration not possible. Developers who were relying on this API should study Mbed OS Storage documentation.

Cellular: Remove friend definitions from cellular state machine

12251

Summary of changes

Instead of defining which classes can access state machine, CellularStateMachine
class is now "a normal" CPP class with public API.

Impact of changes

This is potentially a breaking change but as CellularStateMachine is only used internally there shouldn't be any impact.

Cellular: Remove deprecated CellularDevice::stop()

12249

Summary of changes

Cellular: Remove deprecated CellularDevice::stop()

Impact of changes

Removed method CellularDevice::stop()

Migration actions required

CellularDevice::shutdown() should be used instead.

Cypress: add SoftAP host tests

12240

Summary of changes

Cypress: Initial commit of SoftAP host tests.
Basic SoftAP test with host as STA.

ESP8266: Add built-in hostname resolution handling (disabled by default)

12234

Summary of changes

Fixes #11982 (some routers fail to work with the UDPSocket-approach, but are proved to work when ESP uses its embedded hostname resolution AT command).

The feature is disabled by default and can be enabled in mbed_app.json with "esp8266.built-in-dns": true. When enabled then the synchronous hostname resolution will use the ESP's CIPDOMAIN AT command, but asynchronous resolution will keep on using the UDPSockets as before (no point rewriting the nsapi_dns). Also caching does not work.

I tested with the netsocket-dns testsuite. Obviously caching tests often fail, but if lucky I can get 15/16 passes.

@zhiyong80, please verify if this works with your router.

Impact of changes

None, until user enables the esp8266.built-in-dns option.

Add BufferedSerial class to replace UARTSerial

12207

Summary of changes

Implement the BufferedSerial class to replace UARTSerial. BufferedSerial is UARTSerial renamed to convey the original purpose of the class. Also remove usage of UARTSerial in Mbed OS Core diretories

Update Mbed TLS and Mbed Crypto to latest as of 2019-12-20

12150

Summary of changes

Upgrade to Mbed TLS 2.20.0d1 and Mbed Crypto 3.0.0d0.

Thread: remove methods deprecated in 5.10

12142

Summary of changes

Remove various Thread methods that were deprecated in Mbed OS 5.10

Impact of changes

Code using the old methods will no longer compile

mbed-os-6.0.0-alpha1

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

Summary

This is our first engineering preview of Mbed OS 6.0 focusing on general cleanup and bug fixes. It contains everything that we worked on since December and was deemed ready to merge to master. Please note that this release intentionally breaks compatibility with Mbed OS 5 series. To find out more details please have a look at sections below.

Migration Guide

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

Cellular: Move string_to_pdp_type method to CellularContext

12214

Summary of changes

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

Impact of changes

Migration actions required

Classes derived from CellularContext must implement new function:
virtual const char *get_nonip_context_type_str() = 0;
This API has already been implemented in AT_CellularContext though, so 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 forementioned tests.

Impact of changes

none

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 was carrying the unsupported directory for a long time. The main reason was
to enable users to benefit from some form of USB stack. Now when there
is a proper implementation of USB stack in Mbed I think it's time for
unsupported to go. If any other functionality present in this
directory will be needed it'll need to be introduced in Mbed OS
properly.

Impact of changes

As the name suggest 'unsupported' directory was unsupported, but it was there that means our community was free to use any of the functionality present. So in theory it is 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 drivers directory. If you need any other features please consider contributing it properly to Mbed.

Cellular: Refactor cellular variable visibilities

12123

Summary of changes

Cellular: Refactor cellular variable visibilities

• Earlier some variables were public even though used only internally
• Also refactored variables to the end of class definitions
• Removed duplicate _property_array from CellularDevice
• Changed _impl methods as protected

Impact of changes

This can potentially be a breaking change but at least currently none of the existing mbed-os cellular targets required any changes.

Migration actions required

If customer wants to use some cellular variable marked as private, they need to inform @ARMmbed/mbed-os-wan and we can review the case.

ATHandler refactoring

12122

Summary of changes

As ATHandler is part of Cellular's public API it is now moved to /API folder
Also some functions and variables are refactored to be private/protected where applicable
Also virtual cmd_start() (and destructor) method(s) devirtualised because not needed.
Unittests updated to reflect changes

Impact of changes

As ATHandler is part of Cellular's public API it is now moved to /API folder
Also some functions and variables are refactored to be private/protected where applicable
Also virtual cmd_start() (and destructor) method(s) devirtualised because not needed.

Migration actions required

Visibility of some methods have been changed in ATHandler and should not cause any issues if those were not used (as they shouldn't have been).
Also if include path has been used correctly for ATHandler.h there are no cahnges needed

ONME-4433 SocketAddress::operator== should also check port

12120

Summary of changes

Currently SocketAddress::operator== does not check port number. Adding this check can be considered as a breaking change. Now SocketAddress::operator== checks port also. All greentests and unitests was checked and fixed.

Expose target_offset and header_offset parameters in targets.json

12081

Summary of changes

The app_offset and header_offset parameters have always been a part of the target configuration parameters. However, they were intercepted by the tools and never exposed to the application. The new FOTA (update client next generation) functionality requires these parameters in the code as well now. So this PR adds them to targets.json file. The only result of this PR is the addition of these two macros into the code.
Note that the tools already expose the macros APPLICATION_ADDR and HEADER_ADDR having the same values. However, these macros are only available when the application is built with the bootloader. If it isn't, these macros aren't available, hence this PR.
This change is required for new fota client.

Enabling small C library option and deprecating uARM toolchain

12068

Summary of changes

1. In Mbed-OS 2-region memory model, ARM Std and Microlib scatter files are common
   more info on https://github.com/ARMmbed/mbed-os/blob/master/docs/design-documents/platform/memory-model/ram_memory_model.md,
   so replaced ARM Std scatter file 1-region memory model with Microlib scatter file 2 region memory model.
2. Moved the "__aeabi_assert" function from Microlib boot code file to mbed_retarget file so that it can be available for both RTOS Microlib and bare metal to resolve the undefined symbol linker issue.
3. Copied ARM Microlib boot code into ARM std boot code and guarded with __MICROLIB. This is required in order to build a RTOS application with Microlib.
4. Added a new target config "supported_c_libs" in targets.json and build tools to check if the selected "default_lib" is supported for the selected toolchain. If not the build tool will raise an exception.
5. Added the new test suite for testing the build tool changes for default_lib and supported_c_libs.
6. PR changes tested with blinky and blinky bare metal examples and greentea bare metal tests run locally.

Impact of changes

With these changes, uARM toolchain is being deprecated.

Migration actions required

As uARM toolchain is deprecated, the user has to redefine a supported_c_libs configuration with "small" for arm toolchain on the target in targets.json to enable Microlib support like

"supported_c_libs": {
"arm": ["std", "small"],
"gcc_arm": ["std", "small"],
"iar": ["std"]
}

and change the scatter file to the 2-region memory model see more info.
Instead of -t uARM, use default_lib with "small" in mbed_app.json configuration for ARMC6 toolchain.

cmsis: remove arm math

12055

Summary of changes

Not needed file, should be part of DSP. The functionality is part of the library provided
by CMSIS.

I would like to test this, for all devices. This header file should be removed in 6.0.0 as we do not provide DSP library. Thus I set this as Major update.

Fixes #12054

Impact of changes

Applications should use CMSIS DSP package. As the order of includes is not defined in our tools, this might cause an error - hard to tell which cmsis math header was actually included. The removed math header we used in this code base was much older version.

Migration actions required

Use CMSIS DSP release (not part of Mbed OS at the moment) - the header file cmsis math is included there.

SharedPtr: add nullptr constructor

12048

Summary of changes

For consistency with std::shared_ptr, and mbed::Callback, and as a
potential optimisation aid, give SharedPtr a distinct constructor for
nullptr.

Impact of changes

• Optimise clearing by adding nullptr overload.

Migration actions required

• The added nullptr overload means SharedPtr(NULL) or SharedPtr(0) will no longer work; users must use SharedPtr(nullptr) or SharedPtr().

Add MBED_FALLTHROUGH attribute

mbed-os-5.15.0

We are pleased to announce the Mbed OS 5.15.0 release is now available.

Summary

This is the last planned minor release from the Mbed OS 5 series and, as such, doesn't contain many new features. We focused on fixing issues and working on quality and size improvements.
We put a lot of effort into networking, working on various improvements to Wi-SUN, Cellular and DNS, as well as BG96 and ESP2866 modules drivers. We also introduced support for offloading TLSSockets to an external hardware module.
We updated our tools to support Python 3, so they are ready for the imminent end of life of Python 2.7.
We introduced the static pin map extension to the HAL layer, which allows developers to save memory by selecting the used pins at compile time.
We also updated our code base and infrastructure to use the newest versions for compilers: GCC9 and Arm Compiler 6.13.

Migration guide

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

Add support for Wi-SUN RF channel configuration

11958

Summary of changes

Added support for Wi-SUN RF channel configuration options to Wi-SUN tasklet.

Impact of changes

Wi-SUN RF channel .json options have effect on channel configuration, and they need to be valid.

Migration actions required

Default configuration used with Wi-SUN should be that none of the settings affected by this pull request are set, and Wi-SUN will use the defaults for them.

If application .json configuration file has any of the these settings defined:

wisun-uc-channel-function
wisun-bc-channel-function
wisun-uc-fixed-channel
wisun-bc-fixed-channel
wisun-bc-interval
wisun-bc-dwell-interval
wisun-uc-dwell-interval

they need to be removed or checked for validity.

Remove string-based API usage within mbed-os

11941

See #11914 for deprecation information. This PR provides SocketAddress-based APIs if they were missing after previous changes but does not remove the old APIs.

Summary of changes

New SocketAddress based API added to ESP8266 module, anticipating future string-based API removal.

Impact of changes

None.

Migration actions required

None.

Updates to tools for Python 3 compatibility

11921

Python 3 is now supported by the tools.

Summary of changes

No functional changes, code should be equivalent.

Impact of changes

Code should be Python 3 compatible.

Migration actions required

None.

Deprecate string-based APIs in IPCore

11914

This is NOT a breaking change, but it is worth notifying all API users that the string-based APIs are going to be removed soon.

Summary of changes

The following API functions are being deprecated and will be removed in Mbed OS 6:

TCPServer (whole class is deprecated already)
TCPSocket::connect(const char *host, uint16_t port);
TLSSocket::connect(const char *host, uint16_t port);
DTLSSocket::connect(const char *host, uint16_t port)
InternetDatagramSocket::sendto(const char *host, uint16_t port, data, size);
InternetSocket::bind(const char *address, uint16_t port);
L3IP:add_ipv4_multicast_group(const char *address);
L3IP:add_ipv6_multicast_group(const char *address)
L3IP:remove_ipv4_multicast_group(const char *address);
L3IP:remove_ipv6_multicast_group(const char *address)
NetworkInterface::get_ip_address()
NetworkInterface::get_netmask()
NetworkInterface::get_gateway()
NetworkInterface::set_network(const char *ip_address, const char *netmask, const char *gateway)
NetworkStack::get_ip_address()
NetworkStack::get_ip_address_if()

Impact of changes

Code gives deprecated warnings whenever old API is used.

Migration actions required

Switch to the new SocketAddress based API.

Bring static pin map extension to master

11892

Summary of changes

1. Provide types that will hold static pin maps for peripherals (PWM, AnalogIn, AnalogOut, SPI, I2C, UART, QSPI, CAN).
2. Provide xxx_init_direct(xxx_t *obj, static_pinmap_t *) functions to HAL API (these functions will not use pin map tables).
3. Provide additional constructors in drivers layer, which will use the xxx_init_direct(xxx_t *obj, static_pinmap_t*) HAL functions.
4. Provide default weak implementations of xxx_init_direct(static_pinmap_t *) functions. These functions will call standard xxx_init(xxx_t *obj, PinName, ...) function (backward compatibility for targets that don't support static pin map mechanism).
5. Provide constexpr utility functions to look up for pin mapping in compile time (requires C++14).
6. Initialize console using static pin map mechanism, so hal\mbed_pinmap_common library is not needed and can be removed.
7. Modify FPGA tests to verify xxx_init_direct(xxx_t *obj, static_pinmap_t*) APIs.

Make SMS configurable in Cellular stack

11873

Summary of changes

Cellular stack now has configurable SMS support. This is added to Cellular mbed_lib.json. It is enabled by default for backward compatibility.

Impact of changes

If one does not need SMS, disable it in mbed_app.json to decrease the application footprint.

Migration actions required

None.

mbed_retarget: Add a minimal console implementation to provide basic functionalities

11796

Summary of changes

Add a minimal console implementation in mbed_retarget to provide basic console functionalities.
A new configuration parameter platform.stdio-minimal-console-only has been added to select it.

Impact of changes

Smaller memory footprint for applications that only require basic console functionalities.

Migration actions required

None.

Deprecates NVStore

11785

Summary of changes

NVStore is marked as deprecated.

Impact of changes

NVStore won't be available from the next major release onward.

Migration actions required

Users must switch to use KVStore. For documentation, please see Docs APIs Storage KVStore .

Update to Mbed TLS 2.20.0d0 and Mbed Crypto 2.1.0d0

11687

What is breaking?
The PSA Crypto secure element (SE) driver API - an additional parameter (a persistent data pointer) is now also passed to the slot validation for the driver to use.

Why is this breaking?
Mbed OS tracks the unstable PSA Crypto API. This particular break is to enable drivers to modify persistent data during slot validation.

Migration
Users implementing SE drivers should add an additional void *persistent_data parameter to the slot validation callback, regardless of whether the persistent_data will be used or not.

Old	New
psa_drv_se_validate_slot_number_t did not have a modifiable persistent_data parameter	psa_drv_se_validate_slot_number_t now has a modifiable persistent_data parameter

New declaration of psa_drv_se_validate_slot_number_t:

typedef psa_status_t (*psa_drv_se_validate_slot_number_t)(
psa_drv_se_context_t *drv_context,
void *persistent_data,
const psa_key_attributes_t *attributes,
psa_key_creation_method_t method,
psa_key_slot_number_t key_slot);

Old declaration of psa_drv_se_validate_slot_number_t:

typedef psa_status_t (*psa_drv_se_validate_slot_number_t)(
psa_drv_se_context_t *drv_context,
const psa_key_attributes_t *attributes,
psa_key_creation_method_t method,
psa_key_slot_number_t key_slot);

Check return of BlockDevice::init() in TDBStore.

11595

TDBSTore::init() is now allowed to return error codes from underlying BlockeDevice.
Previously, the API was limited to return only MBED_ERROR_READ_FAILED or MBED_ERROR_WRITE_FAILED, which might have hidden the actual error code from the device.
Now, the application will get the original return value passed from BlockDevice.

modified Wi-SUN tasklet to return success when calling connect twice

11556

Summary of changes

As stated in the Mesh API documentation, we should return the status NSAPI_ERROR_IS_CONNECTED if connect is called twice. This PR (11556) fixes it.

Impact of changes

If connect method is called twice, a different status code is returned.

Migration actions required

Implementations that rely on NSAPI_ERROR_DEVICE_ERROR status code when calling connect twice as their recovery method need to change the handling to the correct status NSAPI_ERROR_IS_CONNECTED.

Enable DER coded certificate support to Wi-SUN mesh API

11539

Added support for DER formatted certificates and keys to Wi-SUN certificate API.

DNS manual cleanup mechanism added

11535

Add nsapi_dns_reset() function to be able to clear a DNS cache when it is not needed anymore.

ESP8266 unlocks deep sleep when disconnected

This release contains changes for ESP8266.
UART input is enabled and deep sleep is locked:

• If module is connected to the network.
• For operations which communicate with the devic...

mbed-os-5.14.2

We are pleased to announce the Mbed OS 5.14.2 release is now available.

Summary

In this release we have added the following targets:

• CY8CKIT_064S2_4343W
• DISCO_H747I (CM7 core)
• DISCO_H747I_CM4 (CM4 core)
• CYW9P62S1_43012EVB_01

As an exception to our normal patch release rules we have added a new API called get_ipv6_link_local_address in NetworkInterface class. This API returns IPv6 link local address.

The QSPI interface permits the alt (aka mode) bits to be any multiple of the bus width. Previously the values
in qspi_alt_size_t only supported multiples of bytes. This has been fixed in this release. This is a backwards
compatible change as compatibility macros are provided for the old qspi_alt_size_t values.

We have updated LittleFS to v1.7.2. The release notes for this change can be found here:

• v1.7.2: https://github.com/ARMmbed/littlefs/releases/tag/v1.7.2
• v1.7: https://github.com/ARMmbed/littlefs/releases/tag/v1.7.0

The Cypress WiFI Host Driver (WHD) has been updated to version 1.40. This includes the following changes:

• Security fix (KRACK all-zero-key)
• Fixed Wi-Fi connection issue after receiving DISASSOC_IND messages
• Fixed ioctl buffer length overflow
• Added API input argument checks

It should be noted that the base target name for NU_PFM_M2351_CM has been changed to NU_PFM_M2351 in this release.

We have fixed the following reported issues:

• 11530 Gaps in QSPIFBlockDevice SFDP Implementation
• 11413 Board will not enter Deep Sleep after communications with Cell Module

mbed-os-5.14.0

We are pleased to announce that the Mbed OS 5.14.0 release is now available.

Summary

This release continues to improve and stabilize Mbed OS. We added a static mode for the event queue, which doesn't require using dynamic memory. This aligns the event queue's memory usage with other parts of the system, including RTOS. You can still use dynamic memory, but if you are worried about memory fragmentation or know your memory requirements upfront you can only rely on static memory. We updated the version of C++ standard to C++14, to leverage modern features of the language. We implemented multiple changes to our connectivity, including PPP support for the Nanostack and enterprise security for WiFi. A big item that we started working on is splitting our public interfaces from the internal code; the work for the OS core is done, and we'll continue this work in future releases for other parts of the system. It will add clarity and help our users use only public and stable APIs. We introduced a minimal version of the standard library printf family calls, which addresses most of the common use cases in a fraction of the memory footprint. We continued to update our PSA support to track the upstream development in PSA and Trusted Firmware. We doubled our effort in tracking and fixing Coverity warnings, reducing the number by 50%.

Compatibility

This release is compatible with Device Management Client 4.0.0

Migration Guide

This section lists changes that may require your attention.

Update Mbed OS for PSA Crypto API 1.0b3

11315

Background

Mbed Crypto is our implementation of the PSA Crypto APIs. We shipped an implementations of prerelease versions of the PSA Crypto API in Mbed OS 5.11, 5.12, and 5.13, with a warning in the documentation that these APIs were subject to change and that we did not intend to maintain backwards compatibility with them. The PSA Crypto API has continued to develop and change over the past few months and a number of breaking changes have been made since the pre-release version we based our Mbed Crypto implementation on.

What is being broken?

The PSA Crypto APIs in Mbed OS as shipped in Mbed OS 5.13 are breaking.

PSA Crypto API 1.0b3 API breaking changes, addressed in Mbed OS 5.14 (see #11315)

• Use key attributes structures for key creation
• Make generating or importing a key also allocate the key
• Update key derivation functions to accept chunked inputs
• Update key agreement API
• Align PSA Crypto error codes with other PSA error codes
• Rename functions for consistency with each other and the rest of PSA
• Be consistent in use of stdint types

Expected PSA Crypto API 1.0 API breaking changes, to be addressed in the next Mbed OS release

• None

Why is it being broken?

Mbed Crypto needs to track the upstream PSA Crypto API as maintained by ATG in order to pass ATG's PSA Compliance Kit tests. The PSA Crypto API was not yet finalized in Mbed OS 5.13 and continues to evolve. We shipped an implementation in Mbed OS 5.13 to enable other teams working on Mbed OS to develop their services a top APIs that should be mostly similar to the final APIs, rather than save up all the integration pain for a later Mbed OS release when the APIs are finalized.

Analysis of impact on users

There should be no surprises to users based on our statements of PSA API instability. We've worked with Mbed TLS, Pelion Client, Storage (ITS), SPM, and Attestation teams to ensure the message of API instability was understood and to coordinate our changes to the API. There are potentially other users of the PSA Crypto API, and our documentation states the stability level of the API for these users.

Alternatives

We could continue to provide the version of the PSA Crypto API shipped with Mbed OS 5.13, but to save flash size and reduce the maintenance burden of maintaining an API we clearly communicated we'd be breaking in the next release, this was deemed not worth the cost.

Mitigation and migration path for users

Users must update to use the new version of the API.

Renaming of key pair names

Replace KEY_PAIR in names that would have used KEYPAIR in the previous API version. For example, PSA_KEY_TYPE_ECC_KEY_PAIR replaces PSA_KEY_TYPE_ECC_KEYPAIR.

Using persistent keys

Use psa_open_key() to open a persistent key. Previously, volatile keys could also be opened. With PSA Crypto API 1.0b3, keys are implicitly opened for you upon import, generation, or derivation.

psa_status_t psa_open_key(psa_key_id_t id,
                          psa_key_handle_t *handle);

Only persistent keys can be opened, so there is no need to pass the lifetime anymore.

It is no longer necessary to call psa_create_key() to make a key persistent. A key is persistent if it is created with a lifetime other than PSA_KEY_LIFETIME_VOLATILE. As part of key creation, use psa_set_key_id() to set both the key's persistent identifier and to set the lifetime to persistent and then call the key creation routine: like psa_generate_key() or psa_import_key()

Old	New
psa_open_key()	Only use for opening previously created persistent keys
psa_create_key()	psa_set_key_id() Keys with IDs are made persistent implicitly upon creation

Allocating keys

Key creation will implicitly allocate resources as necessary, so psa_allocate_key() has been removed from the API and is no longer needed.

Old	New
psa_allocate_key()	Not necessary. Delete calls to psa_allocate_key().

Importing keys

Previously, you had create a policy structure and pass many function arguments to communicate the properties you wanted the imported key to have. Now, you describe them entirely within the attributes structure, passing only the attributes and data to psa_import_key().

Old	New
psa_key_policy_init()	psa_key_attributes_init()
psa_key_policy_set_usage()	psa_set_key_usage_flags(), psa_set_key_algorithm()
Pass key type to psa_import_key()	psa_set_key_type()
psa_set_key_policy()	Pass the attributes to psa_import_key()
psa_import_key()	psa_import_key()

Generating keys

Previously, you had create a policy structure and pass many function arguments to communicate the properties you wanted the imported key to have. Now, you describe them entirely within the attributes structure, passing only the attributes and data to psa_generate_key().

Old	New
psa_key_policy_init()	psa_key_attributes_init()
psa_key_policy_set_usage()	psa_set_key_usage_flags(), psa_set_key_algorithm()
Pass key type to psa_import_key()	psa_set_key_type()
psa_set_key_policy()	Pass the attributes to psa_import_key()
psa_generate_key()	psa_generate_key()

Reading key policy or information

What used to be two functions with many parameters each is now one function that returns the attributes in one structure, in the same format you'd use to create new keys.

Old	New
psa_get_key_policy(), psa_get_key_information()	psa_get_key_attributes()

Deriving keys

The previous "generator" class of functions has been renamed to "key_derivation". The psa_crypto_generator_t structure was previously used to derive keys. Use of the psa_key_derivation_operation_t structure replaces psa_crypto_generator_t for deriving keys.

Old	New
psa_crypto_generator_t	psa_key_derivation_operation_t
psa_generator_abort()	psa_key_derivation_abort()
psa_get_generator_capacity()	psa_key_derivation_get_capacity()
Function parameter	psa_key_derivation_set_capacity()
psa_generator_read()	psa_key_derivation_output_bytes()
Use of generator with PSA_ALG_SELECT_RAW	psa_raw_key_agreement()
psa_key_derivation()	Deriving keys now uses key derivation objects and consists of multiple parts. See the getting started guide for details.

Key agreement

Old	New
psa_key_agreement()	psa_key_derivation_setup(), psa_key_derivation_key_agreement(), psa_key_derivation_output_key()

Hashing

Note: Not yet implemented

The PSA Crypto API 1.0b3 adds a few new functions to help with hashing. Specifically, functions to perform one-shot computation or comparison of hashes.

Old	New
Many hash function calls	psa_hash_compute()
Many hash function calls	psa_hash_compare()

Computing or verifying a MAC

Note: Not yet implemented

The PSA Crypto API 1.0b3 adds a few new functions to help with working with MACs. Specifically, functions to perform one-shot computation or comparison of MACs.

Old	New
Many MAC function calls	psa_mac_compute()
Many MAC function calls	psa_mac_verify()

Symmetric cryptography

Note: Not yet impleme...
