Skip GNUARM startup initialization

by Summer Qin

Hi, There is no forwarded define for '__START' in the current TF-M design, then the runtime init provided by toolchain is applied. This runtime init did something unnecessary as the data copying and ZI has been done already by the startup code, jumping to spm::main would be the next job as SPM would prepare runtime environment for subsequent partition execution and itself won't need other runtime operations besides the data moving. I have created a patch to jump to main under GNUARM: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5609 Change the code is because this would easy the code reading -- most of the users won't check a compiler flag given in the build system for forwarding '__START', so they will try to find the __start from the toolchain source. Currently, we can not avoid depending on ARMCLANG runtime init, so need double check (also IAR). Please provide your feedback, we are changing the platform startup code and need your confirmation to see if it is applicable. Best Regards, Summer

Re: [TF-M] TF-M build system update heads-up

by Raef Coles

Note that it's also still possible to use the "old style" cmake syntax: ``` mkdir build cd build cmake -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake .. make ``` Ninja is also supported as a generator by using ``` mkdir build cd build cmake -GNinja -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake .. ninja ``` This has been noted in the updated build documentation patch, which will be pushed to review.trustedfirmware.org as soon as possible (with other bugfixes, including both of the bugs encountered earlier in the email chain).

Re: [TF-M] PSA tests: NVMEM section

Hi Øyvind, IMOO, such a NVME area is psa-arch-tests dedicated requirement, instead of TF-M implementation or FF-M definitions.

Re: [TF-M] TF-M build system update heads-up

by Gyorgy Szing

Hi Chris, You need two dashes before install. Options with a single dash are processed by cmake. Options after a double dash (--) are passed over to the build tool (in this case gnumake). (See the cmake documentation [1].) So: cmake -B cmake_build -- install is the correct command. [cid:image001.png@01D68392.B953F780] I attached an image above to work around potential readability issues of some font sets. I hope it gets trough.

Re: [TF-M] Changes to configure FPU at the architectural level in TF-M

by Robert Rostohar

Hi Soby, Hi Ken, Thanks for your replies. As mentioned before, majority of device vendors already provide system files (CMSIS standard) which configure also FPU. Take a look for example at the system file provided for STM32L5xx device family (part of STM32CubeL5 FW): https://github.com/STMicroelectronics/STM32CubeL5/blob/master/Drivers/CMSIS… Porting TF-M to a new device should be even simpler when such files can be used directly (or with as less modifications as possible). I'm not just looking at the few platforms that are directly supported within TF-M repo but rather how to reduce efforts to enable TF-M on any CMSIS-Core compliant device. Note: If current system files provided by vendors do not properly configure security features then this should be highlighted. Best regards, Robert From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Soby Mathew via TF-M Sent: Wednesday 2 September 2020 16:00 To: Ken Liu <Ken.Liu(a)arm.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Changes to configure FPU at the architectural level in TF-M Hi Robert, The current architecture abstraction depends on the some CMSIS standard macros (like __FPU_USED) to be defined and if there are vendor tools which can generate the same system file, as long as they are using the standard macros, the architecture abstraction should work alright if the generated file can be included. As Ken says, this makes architecture initialization uniform across platforms and provides the right settings to be applied for security. It also reduces the platform porting effort for new platforms. Hence the move in such a direction. If we allow a mechanism to allow the platform provided system file to be used rather than the default system file, will that suffice your requirement ?

Meanwhile, we would notify the platform owner checking the platform-specific setting. After all platform vendor confirmed the setting of FPU we can leave this back to platform setting as you suggested - but secure firmware core logic still needs to check if platform set the FPU setting correctly. @Soby @Jamie, please update if I missed something.

FPU configuration is typically configured within system configuration files that are standardized in CMSIS and provided by device vendors. Some vendors provide also tools that auto-generate the system file based on user configuration (ex: STM32CubeMX). Therefore it would be better to leave the FPU configuration to the platform rather than moving it into architecture-abstraction.

The reasoning for this is that these registers are defined by the Arm architecture, so FPU config can be unified for all platforms with the same architecture. For Armv8-M, this also includes configuration to ensure that information is not leaked in FPU registers to NSPE when the SPE uses the FPU, and to permit the NSPE to access the FPU. By default, TF-M will still be built without the FPU used in the SPE. You can review the changes at: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5405 Arch: Add function to configure coprocessors https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5406 Platform: Remove platform-specific FPU config It would be especially helpful if platform owners could check that they are happy with FPU config being moved out of the platform support files.

New build system with IAR

by Thomas Törnblom

I've started looking at the new build system, and it looks like a nice improvement. I have a problem, that likely has a simple solution, although I'm not sure which. I've looked at the AN521 target, and the preload.cmake file is included very early from the root CMakeLists.txt The first line of preload.cmake is: --- set(CMAKE_SYSTEM_PROCESSOR cortex-m33+nodsp) --- For IAR that line should be: --- set(CMAKE_SYSTEM_PROCESSOR Cortex-M33.no_dsp) --- I need to discriminate between the toolchains already there, but I haven't figured out what the best way would be to do that. Not much is setup at this moment in the run. Ideas?

Re: [TF-M] Simpler integration into other projects

by Anton Komlev

Hi Øyvind, Thank you for the proposal. Believe all agreed that NS side shall be separated from S side and be OS independent.

I'm using Zephyr as an example, but I mean that it should apply to any external project that wants to integrate TF-M. I'm assuming the project wants to use the secure FW as is, so no change is needed there. However, in the NS FW we want to integrate the NS callable (PSA) API into native Zephyr applications, but the NS ("app") part of TF-M has some OS dependencies that interfere with this. My proposal is that the TF-M build system creates OS-independent NS libs that can be linked directly into the native Zephyr app. Ideally, the Zephyr build system should need to only do the following: - Call TF-M build system. - Retrieve S binaries (and optionally mcuboot binary). - Link NS lib(s) into project app. - Add include directories to NS callable API. Additionally, the RTOS will likely need to make an OS wrapper to support the OS functions needed. Please tell me your thoughts. I'm not an expert in Cmake and libs, so please also tell me if the above is infeasible in any way. I think making such integrations as simple as possible will be very beneficial, not just when doing the initial integration, but continuously, since changes in TF-M will eventually require tweaks in the integration.

Re: [TF-M] CI Checkpatch

by Soby Mathew

Thanks Gyorgy for your inputs. My only concern with git hooks is that they are triggered when patches are pushed for review whereas checkpatch is something needs to be frequently run for non-trivial patchsets. The other issue is I am not sure whether we can pass different arguments to githooks whereas build system integration allows that (for example check the entire tree vs only the changed lines). Also having it part of regular build allows easier integration with work flow. Hence many OSS projects integrate this into regular build for this reason. But as you say, perhaps the first solution is to download the script and run locally and I don't have a strong opinion against git hooks either. Whatever works best can be used.

Sort term Sort term it is possible to clone the ci-scripts repository and to run the check-patch script locally (https://git.trustedfirmware.org/ci/tf-m-ci-scripts.git/tree/run-checkpatch.…) . The script has some in-line documentation. Long term I think this is an automation topic which may have a connection to the build system, but the right place for a solution in not there. When it comes to automation the best is to differentiate two use cases: 1. Centralized. This is where the automation happens on a server, and the main purpose is to keep authentic records about quality, or to drive delivery (i.e. push documents to hosting provider.) For this we have Jenkins. 2. De-centralized. This is when the automation is executed on the developers machine. How the user interacts with this system can be an implementation detail. The same scripts could be executed by git hooks, manually, or by the build system. I think the best solution would be to use git-hooks for decentralized automation, as this is there already, and has a well defined and standard interface towards the developer. The main problem with git hooks is, git as a policy leaves hook management as the responsibility of the developer, and there is no built-in way to deploy hooks to the developers machine.

Re: [TF-M] Changes to configure FPU at the architectural level in TF-M

by Soby Mathew

Hi Robert, The current architecture abstraction depends on the some CMSIS standard macros (like __FPU_USED) to be defined and if there are vendor tools which can generate the same system file, as long as they are using the standard macros, the architecture abstraction should work alright if the generated file can be included. As Ken says, this makes architecture initialization uniform across platforms and provides the right settings to be applied for security. It also reduces the platform porting effort for new platforms. Hence the move in such a direction. If we allow a mechanism to allow the platform provided system file to be used rather than the default system file, will that suffice your requirement ?

Meanwhile, we would notify the platform owner checking the platform-specific setting. After all platform vendor confirmed the setting of FPU we can leave this back to platform setting as you suggested - but secure firmware core logic still needs to check if platform set the FPU setting correctly. @Soby @Jamie, please update if I missed something.

FPU configuration is typically configured within system configuration files that are standardized in CMSIS and provided by device vendors. Some vendors provide also tools that auto-generate the system file based on user configuration (ex: STM32CubeMX). Therefore it would be better to leave the FPU configuration to the platform rather than moving it into architecture-abstraction.

The reasoning for this is that these registers are defined by the Arm architecture, so FPU config can be unified for all platforms with the same architecture. For Armv8-M, this also includes configuration to ensure that information is not leaked in FPU registers to NSPE when the SPE uses the FPU, and to permit the NSPE to access the FPU. By default, TF-M will still be built without the FPU used in the SPE. You can review the changes at: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5405 Arch: Add function to configure coprocessors https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5406 Platform: Remove platform-specific FPU config It would be especially helpful if platform owners could check that they are happy with FPU config being moved out of the platform support files.

Re: [TF-M] psa_key_id_t type mismatch --- HardFault

by David Hu

Hi Alamy, In my very own opinion, `psk_key_id_t` defined as structure seems to be Mbed Crypto/MbedTLS own definition and should be transparent to applications calling `psa_open_key()`, as described in https://github.com/ARMmbed/mbedtls/blob/v2.23.0/include/psa/crypto_platform…. TF-M provides standard PSA APIs and therefore the `psa_key_id_t` in `psa_open_key()` is `uint32_t` as defined in PSA Cryptography API v1 Beta 3. The `uint32_t` `psa_key_id_t` is defined in `interface/include/psa/crypto_types.h` and included by TF-M Crypto interface files. Then when TF-M Crypto service invokes Mbed Crypto/MbedTLS APIs to fulfill the `psa_open_key()`, it includes Mbed Crypto/MbedTLS specific header file, in which `psa_key_id_t` is defined as a structure to support multiple client. For example, `crypto_key.c` constructs a `psa_key_id_t` structure and pass it to Mbed Crypto/MbedTLS `psa_open_key()` implementation.

Simpler integration into other projects

by Rønningstad, Øyvind

Hi list I have a proposal to make it easier to integrate TF-M into other existing projects, e.g. RTOSes such as Zephyr. I'm using Zephyr as an example, but I mean that it should apply to any external project that wants to integrate TF-M. I'm assuming the project wants to use the secure FW as is, so no change is needed there. However, in the NS FW we want to integrate the NS callable (PSA) API into native Zephyr applications, but the NS ("app") part of TF-M has some OS dependencies that interfere with this. My proposal is that the TF-M build system creates OS-independent NS libs that can be linked directly into the native Zephyr app. Ideally, the Zephyr build system should need to only do the following: - Call TF-M build system. - Retrieve S binaries (and optionally mcuboot binary). - Link NS lib(s) into project app. - Add include directories to NS callable API. Additionally, the RTOS will likely need to make an OS wrapper to support the OS functions needed. Please tell me your thoughts. I'm not an expert in Cmake and libs, so please also tell me if the above is infeasible in any way. I think making such integrations as simple as possible will be very beneficial, not just when doing the initial integration, but continuously, since changes in TF-M will eventually require tweaks in the integration. Best regards, Øyvind Rønningstad

Re: [TF-M] Changes to configure FPU at the architectural level in TF-M

by Ken Liu

Hi Robert, Thanks for the comment, just want to double check if the guidelines for vendors who providing platform sources to a secure software covers the recommendations here: https://lists.trustedfirmware.org/pipermail/tf-m/2020-June/001007.html As far as we can see not all existing platforms set the registers required in the above recommendation (In Jamie's second patch), so we are trying to provide an architecture-abstraction. Meanwhile, we would notify the platform owner checking the platform-specific setting. After all platform vendor confirmed the setting of FPU we can leave this back to platform setting as you suggested - but secure firmware core logic still needs to check if platform set the FPU setting correctly. @Soby @Jamie, please update if I missed something.

Re: [TF-M] CI Checkpatch

Hi Chris, The CI job was trigged from https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/3521, you could find a list of all jobs and status of each job on Gerrit page that triggered by that job, job list example can be found at the end of this email.

[RFC] The code review guideline

by Ken Liu

Hi, We are creating one document to describe the code review guidelines: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5372 The goal of this document is to introduce the source management level concepts to be followed while reviewing a code – which try to simplify the contribution (but burdens the reviewers? 😉). Difference to the `coding style`: * It focuses more on the source placement, interface definition and including, etc. As this document is keeping evolving in a period, the plan is we merge a simple version as start and adding more contents by new patches, so please give enough comments if you have, and don’t forget the concept: we want to make things rational and simple. Thanks. /Ken

Re: [TF-M] New build system with IAR

by Gyorgy Szing

Hi, CMAKE_SYSTEM_PROCESSOR identifies the CPU the build targets. If this string is passed to the compiler as a command line flag, that seems to be an error to me. Also I have the feeling that this value should be more hardware specific. A Cortex-M33 CPU has many configuration options to be set when it is put into a system, and different set of options may need different compiler switches. All this complexity might not be needed in the build-system and it could be better to hide it. I suggest naming the CMAKE_SYSTEM_PROCESSOR after the "chip" (i.e. AN521). The compiler specific files can map this name to the appropriate set of compiler options, and the compiler will set the "feature test macros" described in [1]. Source code can use these macros to configure itself properly. In the build system only features having an effect on CMake files shall be visible. (I.e. if a feature needs a different file to be compiled in.)

-DBL2=False causes duplicates in ASM_FLAGS in makefiles

by Thomas Törnblom

For some reason that I've not been able to track down, using -DBL2=False on the cmake command line causes ASM_FLAGS to have duplicated debug flags and defines. It does not happen to C_FLAGS and it doesn't happen with -DBL2=True. I've worked around the issue in https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5365, but a cleaner solution would be to avoid this in the first place. I would appreciate if someone with more cmake experience could have a go at this. It causes build failures with IAR, and ARMCLANG and GNUARM doesn't care about the duplicates.

Hi Soby ;) I'm currently using an MPS2+ board with the AN539 system to experiment with TF-M code for a new M33-based, IC design. Does "deprecating the AN539 platform" effectively mean deprecating TF-M support for the MPS2+ FPGA platform entirely? In other words: is AN539 the only example subsystem for the MPS2+ board that supports the M33 and TF-M? If it is, then I'd like to object (for what that's worth!)

Re: [TF-M] Detailed build logfiles

by Gyorgy Szing

Hi, Please see the file “pipeline.log” on the artifacts tab, or based on the job name and build number (tf-m-static; 428), find the job on the Jenkins main page (https://ci.trustedfirmware.org/). Then check the console output using the menus related to the build number (https://ci.trustedfirmware.org/view/TF-M/job/tf-m-static/428/console). You can find the triggered sub-jobs the same way (in you case tf-m-build-and-test #434; https://ci.trustedfirmware.org/view/TF-M/job/tf-m-build-and-test/434/console). At a quick glance some lava errors seem to be the root cause: Calling: 'nice' 'docker' 'pull' 'REPLACE_DOCKER_PREFIX/lava-fvp-mps2' >> invalid reference format: repository name must be lowercase see here: https://tf.validation.linaro.org/scheduler/job/9372 Note: I did not made a full investigation, just a quick check.

Re: [TF-M] TF-M repository restructure

Hello, This is a kind reminder on TF-M repository change below. The old URL will be alive for the following 3 months before depreciation. Regards, Anton From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Anton Komlev via TF-M Sent: 14 May 2020 15:32 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] TF-M repository restructure Hello, Let me announce the changes in TF-M project repository structure. To allow project grow up in a more organized way the existing codebase will be split on multiple repositories and placed under TF-M folder. This is the similar structure as all other projects have in git.trustedfirmware.org<https://git.trustedfirmware.org>. This weekend TF-M git repository will be moved from https://git.trustedfirmware.org/trusted-firmware-m.git to https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git The original URL will be supported for some time (as a link to the new one) giving time for adjustment. Current plan is to keep the redirection for 6 months but let me know please, if it makes any conflict and another depreciation period is better. Best regards, Anton Komlev

Patch to upgrade crypto service to use latest mbedTLS tag (v2.23.0)

by Soby Mathew

Hi Everyone The following patch updates the crypto service in TF-M to use the latest mbedTLS tag v2.23.0. All reviews for the same will be much appreciated. https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5252/1 With this update, additional PSA APIs psa_hash_compute() and psa_hash_compare() are now supported. There is also another patch for platforms to update the ITS_MAX_ASSET_SIZE when testing with PSA Crypto API compliance test as one of the tests require a larger size: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5253/1 . Could the platform owners review the same and let me know whether the size changes are OK ? With the above patches, the API compliance remains the same as v1.0 Beta 3 and the PSA Crypto compliance test suite gives the below results (as tested on AN521) : ************ Crypto Suite Report ********** TOTAL TESTS : 61 TOTAL PASSED : 42 TOTAL SIM ERROR : 0 TOTAL FAILED : 17 TOTAL SKIPPED : 2 ****************************************** Best Regards Soby Mathew

Proposal to separate SCT/LD into each platform folder

by Shawn Shan

Hi all, There are many differences in linker scripts between each platform. Using a common_s.sct/ld makes it too complicated. And at the same time, in order to achieve isolation level 3, the position of the sessions in scatter and linker script file needs to be adjusted. The common linker scripts would be more complicated with isolation L3. So I would like to propose to have dedicated linker scripts for platforms with enough differential arrangements. What's your opinion on this? Best regards, Shawn

New build system WIP

by Raef Coles

Hi all The new buildsystem (work in progress) is now available at https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5039. Comment would be very much appreciated. There have been some minor interface changes to how the buildsystem is invoked. a sample invocation is: cmake -S .. \ -B . \ -G"Unix Makefiles" \ -DTFM_PLATFORM=musca_s1 \ -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake \ -DCMAKE_BUILD_TYPE=release -DBL2=ON \ -DNS=ON \ -DTFM_PSA_API=ON \ -DTEST_NS=ON -DTEST_S=ON \ -DTFM_ISOLATION_LVL=2 More specifically cmake -S [Source_dir (often ..)] \ -B [build_dir (often .)] \ -G ["Unix Makefiles" OR Ninja] \ -DTFM_PLATFORM=[musca_b1 OR musca_s1 OR mps2/an521 OR cypress/psoc64 ETC...] -DCMAKE_TOOLCHAIN_FILE=[build_dir/toolchain_GNUARM.cmake OR build_dir/toolchain_ARMCLANG.cmake] -DCMAKE_BUILD_TYPE=[release OR debug OR minsizerel OR relwithdbginfo] -DBL2=[OFF OR ON] -DNS=[OFF OR ON] -DTFM_PSA_API=[OFF OR ON] -DTEST_NS=[OFF OR ON] -DTEST_S=[OFF OR ON] -DTFM_ISOLATION_LVL=[1 OR 2] Note that this interface is not set in stone and may change before these patches are merged. The new buildsystem is currently missing a few of the platforms, as well as some features. All of these are planned to be added prior to merging. Notable are dualcpu/Cypress PSoC64 which is currently being finalized, documentation building, and image signing for some of the boot modes which is on the TODO list. Note that unlike previous versions, this should work "out the box" with regard to dependencies. The paths for dependencies can be set, but some patches to mbedtls that are in the process of being upstreamed are used. These patches are stored in the lib/ext/mbedcrypto directory and can easily be applied manually. Regards, Raef Coles

MCUBoot related changes

by Tamas Ban

Hi, Just a heads-up for the coming changes related to MCUBoot. Some of them requires installing new tools in build system others could affect devices on the field (if there is any) after SW upgrade. Short term, within one week: 1. Official imgtool enablement: * The official released version of the image signings script will be used. * Must be installed in the build system. It is a PyPI package: imgtool v1.6 * https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4564/6 2. Encrypted image support: * This feature already exists in the upstream repo for a while * This change makes possible to turn it on in TF-M build system * https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4565/6 Long term, but still expected in Q3: 1. Removal of forked MCUBoot from TF-M: * Only upstream MCUBoot will supported * Platform and project related files will be kept: i. shim layer to match MCUBoot HAL's to TF-M's HAL ii. bl2_main.c, example signing keys, keys.c iii. platform code: flash and UART drivers, implementation of boot_hal.h * When building TF-M with upstream MCUboot it is a mixture of files from the two repo + crypto code from mbedcrypto repo. * https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4953 * The removal of the fork depends on the feature upstream to MCUBoot repo: i. https://github.com/JuulLabs-OSS/mcuboot/pull/739 ii. RAM_LOAD: PR will come a bit later 1. Removal of LEGACY_TFM_TLV_HEADER support * This is a compatibility mode. It was introduced to hide the difference in the definition of the TLV header int he shared data between bootloader and runtime SPE. * If forked removed, then this is not necessary anymore, unless an forked version of MCUBoot wants to cooperate new SPE. * Please check and indicate if you think that this is a valid use case and compatibility mode must be kept!

Process for deprecating and removing platforms

by Soby Mathew

Hi Everyone, The document in tf.org defines the different "Platform Support Life Cycle": https://developer.trustedfirmware.org/w/collaboration/project-maintenance-p… Although a platform can be implicitly in deprecated state due to lack of support or maintenance, a process to explicitly declare a platform as deprecated with the intention to remove it in future is needed as well. So I have attempted to define a process as described here: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4962/1/docs/… Comments welcome. Best Regards Soby Mathew

Re: [TF-M] Persistent key storage ownership/access

by Andrew Thoelke

Hi, The ITS design requires that all data items are private to its client - it essentially just provides a persistence capability within the same isolation domain. So it is not possible for two distinct clients to access the same stored material, *unless they do this through a common intermediary*. Jamie outlines one approach: PSA Crypto Partition hosts the key store, and delegates the operations to the AES partition. But this fails the concurrency requirement as noted. Another plausible approach is that the AES Partition is a special/trusted client of the PSA Crypto Partition and uses a dedicated service/API to retrieve the AES client's key material. However, this also fails the concurrency objective when the PSA Crypto Partition is busy. Without the IPC model (which allows for nested/interleaved message handling, under service developer control) - the design that would work is to: 1. Create a key store Partition that interfaces with ITS 2. Have the PSA Crypto and AES partitions be trusted clients of the key store (the key store does not allow other client connections) 3. Key management operations go through a PSA Crypto service, which invokes the key store service to store material in ITS 4. AES operations go through a AES service, which invokes the key store service to retrieve key material This model works, but delivering the desired concurrency requires that the framework supports multiple Partitions, and can run one Partition while another is busy/blocked. Note that the key store service is _just_ a proxy to ITS using the key-id + Crypto-client-id supplied by its client. Security depends on the client-ids of the Crypto and AES Partitions being fixed so that the private key store service can strictly enforce which clients can use it.

But note that even if the driver partition could be given permission to access the key, then it wouldn't immediately fix the issue. The driver partition would then need to implement another layer of access control, otherwise partitions would be able to use it as a conduit to access keys that they don't themselves own. I think a more expected flow would look like: 1. NS application calls psa_import_key() to store a key with an ID. Key is stored by ITS with client ID of -1 (DEFAULT_NS_CLIENT_ID). 2. NS application calls an AES crypto function in the PSA Crypto partition and provides the key ID. 3. PSA Crypto partition retrieves the key from ITS for use. Client ID = -1. 4. PSA Crypto partition calls an AES crypto function in the driver partition and provides the key material. But I assume you discarded this approach because it didn't give you the level of concurrency between PSA Crypto and the crypto driver that you wanted.

C preprocessor directives issue for IAR linker

by Andrej Butok

Hello Tomas, I am trying to port TFM to IAR Embedded Workbench v8.50.5 IDE (NOT cmake) for LPC55S69. And have an error during linking in tfm\platform\ext\common\iar\tfm_common_s.icf on #include "region_defs.h": Error[Lc003]: expected ""check", "define", "do", "export", "if", "include", "initialize", "keep", "place", "reserve", or a placement label It can be fixed by changing: #include "region_defs.h" to: include "region_defs.h"; but it creates 44 Errors [Lc003] in region_defs.h, The IAR linker does not understand the C preprocessor directives like #ifndef, #ifdef, #endif etc. How did you solve this IAR issue? As we have to use IAR IDE (not cmake), what is your suggestion? Maybe a special IAR Linker preprocessing parameter/option? Thank you, Andrej Butok

Call for review on TF-M HAL design

by Edison Ai

Hi All, Please review the design of the TF-M HAL: https://review.trustedfirmware.org/c/trusted-firmware-m/+/4076. This new design aims to make the TF-M more simple to integrate and porting to different platforms. The current version only includes the HAL API for the TF-M core, the HAL for Secure Partition will be the next step. Main Context: * There are 6 modules in the Core HAL: * Isolation API: Provides the necessary isolation functionalities required by the PSA FF and TBSA-M, and provides functions to SPM to check the validate of memory access. * Platform API: Provides the platform initial, receives platform data, system reset, etc. * Loader API: Provides the function to load partition and service and provides the necessary data to SPM. * Log dev API: Provides the log system functions. * Interrupt API: Provides the interrupt functions. * Debug API: Provides the debug functions. * There are some sequence diagrams that help you to more quick and easy the using of the new HAL. Main Change: There are some main changes to the TF-M core: * Move most of the platform data from Core to the platform and need tools to support it. * The platform needs to provide the required necessary memory to the Core for its runtime data using. * Load mode change. The platform needs to load the secure partition and provide the necessary info to the core. Please see the design for more details and welcome comments. BR, Edison

[RFC] TF-M Documentation Contribution Format

by Minos Galanakis

Hi, As the project matures, and the community grows, I would like to revive an old discussion and suggest that we set some guidelines for contributing to the project's documentation. I would like to propose that we establish a minimal sub-set of rules, based on the official Python guidelines<https://devguide.python.org/documenting/#style-guide> which is the most widely used notation. This offers compatibility with existing tools for proofing and producing said documentation. The following rules should be considered: 1. H1 document title headers should be expressed by # with over-line (rows on top and bottom) of the text 2. Only ONE H1 header should allowed per document, ideally placed on top of the page. 3. H2 headers should be expressed by * with over-line 4. H2 header's text should be UNIQUE in per document basis 5. H3 headers should be expressed by a row of '=' 6. H4 headers should be expressed by a row of '-' 7. H3 and H4 headers have no limitation about naming. They can have similar names on the same document, as long as they have different parents. 8. H5 headers should be expressed by a row of '^' 9. H5 headers will be rendered in document body but not in menus on the navigation bar. 10. Do not use more than 5 level of heading 11. When writing guide, which are expected to be able to be readable by command line tools, it would be best practice to add long complicated tables, and UML diagrams in the bottom of the page and using internal references(auto-label). Please refer to the `tfm_sw_requirement.rst<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/docs/getti…>` as an example 12. No special formatting should be allowed in Headers ( code, underline, strike-through etc ) 13. Long URLs and external references should be placed at the bottom of the page and referenced in the body of the document 14. New introduced terms and abbreviations should be added to Glossary and directly linked by the `:term:` notation across all documents using it. When something new, which is not covered is required, the rule should be first to follow the any reference to of an existing document, and the Python Documentation rules otherwise. Please let me know if you have any questions/objection or proposals or new rules you would like to consider. Any feedback is more than welcome. Minos

New TrustedFirmware.org security incident process is now live

by Dan Handley

Hi all The new TrustedFirmware.org security incident process is now live. This process is described here: https://developer.trustedfirmware.org/w/collaboration/security_center/repor… Initially the process will be used for the following projects: TF-A, TF-M, OP-TEE and Mbed TLS. The security documentation for each project will be updated soon to reflect this change. If you are part of an organization that believes it should receive security vulnerability information before it is made public then please ask your relevant colleagues to register as Trusted Stakeholders as described here: https://developer.trustedfirmware.org/w/collaboration/security_center/trust… Note we prefer individuals in each organization to coordinate their registration requests with each other and to provide us with an email alias managed by your organization instead of us managing a long list of individual addresses. Best regards Dan. (on behalf of the TrustedFirmware.org security team)

Re: [TF-M] Alignment issues on stack with ITS

by Jamie Fox

Hi Thomas, It is only the size of the struct that needs to be aligned to the flash program unit, so that the write size is aligned when the struct is programmed to flash. So indeed the attribute puts too strong a constraint on the compiler as it also forces it to allocate these structs at aligned addresses on the stack. The only vaguely clean, portable way I can think of aligning up the size of the struct alone is something like: struct its_file_meta_t_padded { struct its_file_meta_t file_meta; uint8_t pad[ITS_FLASH_MAX_ALIGNMENT - (sizeof(struct its_file_meta_t) % ITS_FLASH_MAX_ALIGNMENT)]; }; But that has the disadvantage of adding ITS_FLASH_MAX_ALIGNMENT to the size of the struct in the case that it is already aligned (no zero-sized arrays), as well as the extra step of accessing the nested struct each time. Would be happy to hear any alternative solutions though. Kind regards, Jamie From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Thomas Törnblom via TF-M Sent: 26 June 2020 10:07 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Alignment issues on stack with ITS ITS defines a few structs with specific alignment requirements, like: struct __attribute__((__aligned__(ITS_FLASH_MAX_ALIGNMENT))) its_file_meta_t { uint32_t lblock; /*!< Logical datablock where file is * stored */ size_t data_idx; /*!< Offset in the logical data block */ size_t cur_size; /*!< Size in storage system for this # * fragment */ size_t max_size; /*!< Maximum size of this file */ uint32_t flags; /*!< Flags set when the file was created */ uint8_t id[ITS_FILE_ID_SIZE]; /*!< ID of this file */ }; This causes issues with the IAR compiler when these structs are declared as autos: static psa_status_t its_mblock_copy_remaining_block_meta( struct its_flash_fs_ctx_t *fs_ctx, uint32_t lblock) { struct its_block_meta_t block_meta; psa_status_t err; uint32_t meta_block; size_t pos; uint32_t scratch_block; size_t size; ... The IAR compiler gives these errors if the alignment is 0x10 (the stack is 8 byte aligned): struct its_block_meta_t block_meta; ^ "C:\Users\thomasto\Projects\tf-m1\trusted-firmware-m\secure_fw\partitions\internal_trusted_storage\flash_fs\its_flash_fs_mblock.c",415 Error[Ta121]: Auto variable "block_meta" cannot have a stricter alignment than the stack I assume this alignment is only required for the flash, so the alignment attributes should be set when declaring variables in the flash, not on the type.

Re: [TF-M] Build issues with GNUARM with 7946bdd3

by Anton Komlev

Thanks, Thomas. Yes, it was noted right after RC1 applied. The problem affects the build (not code) on Windows platform only. While waiting for the fix we do continue tests using Linux build. A fix will be applied or the patch reverted before TF-M release or with RC2, if happen.

Alignment issues on stack with ITS

by Thomas Törnblom

ITS defines a few structs with specific alignment requirements, like: struct __attribute__((__aligned__(ITS_FLASH_MAX_ALIGNMENT))) its_file_meta_t { uint32_t lblock; /*!< Logical datablock where file is * stored */ size_t data_idx; /*!< Offset in the logical data block */ size_t cur_size; /*!< Size in storage system for this # * fragment */ size_t max_size; /*!< Maximum size of this file */ uint32_t flags; /*!< Flags set when the file was created */ uint8_t id[ITS_FILE_ID_SIZE]; /*!< ID of this file */ }; This causes issues with the IAR compiler when these structs are declared as autos: static psa_status_t its_mblock_copy_remaining_block_meta( struct its_flash_fs_ctx_t *fs_ctx, uint32_t lblock) { struct its_block_meta_t block_meta; psa_status_t err; uint32_t meta_block; size_t pos; uint32_t scratch_block; size_t size; ... The IAR compiler gives these errors if the alignment is 0x10 (the stack is 8 byte aligned): struct its_block_meta_t block_meta; ^ "C:\Users\thomasto\Projects\tf-m1\trusted-firmware-m\secure_fw\partitions\internal_trusted_storage\flash_fs\its_flash_fs_mblock.c",415 Error[Ta121]: Auto variable "block_meta" cannot have a stricter alignment than the stack I assume this alignment is only required for the flash, so the alignment attributes should be set when declaring variables in the flash, not on the type. Comments?
