- TF-M - lists.trustedfirmware.org

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

psa_key_id_t type mismatch --- HardFault

by Alamy Liu

Dear all, While I was working on the PSoC64 platform, I hit the *psa_key_id_t* type mismatch problem. The patch - *98ab441e096f *enables *MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER* Which in terms to use the *psa_key_id_t* *structure* (psa_key_file_id_t) in <mbed-crypto/mbedtls>/include/psa/*crypto_platform.h* Interestingly, psa_key_id_t is also defined in <tf-m>/interface/include/psa/ *crypto_types.h*, as a uint32_t. So, I do the following testing I could compile the master HEAD no problem *66ee5c8861* (HEAD, origin/master, origin/HEAD) Tools: update iat-verifier README and samples I assume the psa_key_id_t should be a *structure* (from mbed-crypto/mbedtls), I applied the patch below --- a/interface/include/psa/crypto_types.h +++ b/interface/include/psa/crypto_types.h @@ -211,6 +211,8 @@ typedef uint8_t psa_key_persistence_t; */ typedef uint32_t psa_key_location_t;+#if !defined(MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER)+#error Should not compile this /** Encoding of identifiers of persistent keys. * * - Applications may freely choose key identifiers in the range @@ -222,6 +224,7 @@ typedef uint32_t psa_key_location_t; */ typedef uint32_t psa_key_id_t; #define PSA_KEY_ID_INIT 0+#endif Then, I notice that there are still many files that use *uint32_t* psa_key_id_t in the TF-M source tree. a) It's good (lucky?) that TF-M seems to cut it cleanly so it doesn't run into problems (well, it happens on PSoC64, or I won't notice it). b) It's bad that psa_key_id_t in TF-M has two different types. I'm not going to argue what's correct/wrong. Maybe this kind of coding could be a feature in the future. I just go with it. But I found no information to define the boundary of the two types under the <tf-m>/docs/ directory. I would like to know where the boundary is, in TF-M. In other words, *Which part of the code should use the structure definition from mbedtls/mbed-crypto; which part of the code should use uint32_t ?* In my work, the problem happens when it passes psa_key_id_t as a parameter, the parent & child functions see it differently (HardFault, in my case, memory violation to other parameters). e.g.: func_a.c (structure), func_b.c (uint32_t). func_b.h ---- the type changes when it's included by func_a.c and/or func_b.c Regards, Alamy

CI Checkpatch

by Christopher Brand

So I see the CI system runs checkpatch, but I don't see any mention of checkpatch under the "docs" directory, or in any of the gerrit reviews, or even on the mailing list. The output in the CI system, as far as I can see, is not particularly useful (I followed the link posted on my review to https://ci.trustedfirmware.org/blue/organizations/jenkins/tf-m-static/detai… but could find anything indicating what issue was actually found). Is there any documentation on how we can run checkptach manually? Or on how to see what the CI version is actually complaining about? Should I just be ignoring the CI checkpatch errors?

Changes to configure FPU at the architectural level in TF-M

by Jamie Fox

Hi all, There is a change open for review that adds configuration of FPU-related registers to the architecture-abstraction layer in TF-M, and removes this same configuration from platform support files. 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. Kind regards, Jamie

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.)

Re: [TF-M] Patch to upgrade crypto service to use latest mbedTLS tag (v2.23.0)

Just an update to this, I have merged the patch which upgrades to the latest mbedTLS tag. The PSA Arch initial attestation test suite fails to build after this merge due to width change of `ecc_curve_t` type. The issue is reported here in PSA Arch test github project : https://github.com/ARM-software/psa-arch-tests/pull/232 The patch for changing the ITS_MAX_ASSET_SIZE is still outstanding and I hope to merge it after a week.

-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.

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

Hello, The agenda for this forum: 1. Musca-B1 Secure Enclave solution 2. Platform specific vs common scatter/link scripts 3.

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

Hi Thomas >From the log, Your folder seems to indicate trusted-firmware-m and you are trying to push to tf-m-tests.

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.

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.

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.

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.

Switch to the original MCUboot as default

by David Vincze

Hi everyone, I would like to inform you about that the default bootloader option in TF-M has been changed from TF-M's MCUBoot fork to the original MCUBoot by a commit that was merged a few hours ago (https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4551). Due to this you may experience that your TF-M builds are failing after a recent rebase onto master with the following error message: "Missing MCUBoot. Please clone the MCUBoot repo to directory....." . To solve this, you can choose from the following options: 1. Follow the instructions of the 'MCUBoot' section in the docs/getting_started/tfm_secure_boot.rst to clone the MCUBoot repository and fulfill this dependency. 2. Quick but rather temporary solution: Append '-DMCUBOOT_REPO=TF-M' to your CMake configuration command to use the MCUBoot fork from the TF-M repository as before. Example: cmake -G"Unix Makefiles" -DTARGET_PLATFORM=AN521 -DCOMPILER=ARMCLANG -DMCUBOOT_REPO=UPSTREAM ../ Please let me know, if you have any difficulties. Best regards, David Vincze

Thanks Anton. As you may have noticed, the CMSIS RTX libraries have been added to the tf-m-tests. There are also patches<https://review.trustedfirmware.org/q/topic:%22CMSIS_5_to_tfm_tests%22+(stat…> for TF-M to reference the libraries from tf-m-tests.

Re: [TF-M] PS => AP ROT

by Jamie Fox

Hi Andrej, The PSA Storage spec (available here https://developer.arm.com/architectures/security-architectures/platform-sec…) states that the Protected Storage service should be implemented inside the Application Root of Trust. The principle is that the PSA Root of Trust should be kept as small as possible, to reduce the attack surface of the most privileged part of the system. As Protected Storage neither needs the privileges of the PSA Root of Trust nor is used by any PSA Root of Trust service, it should be implemented inside the Application Root of Trust.

Hi, This design addressing to share the code of the common crypto primitives(SHA256, RSA, later AES) between MCUboot and runtime SPE. The goal is to reduce the flash footprint of SPE. Design proposal: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4587 Implementation: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4583/ TL;DR: SPE binary size can be reduced with 10KB. If image encryption will be turned on then ~12-13KB is the gain. Please let us know if you think this improvements would be useful. @Thomas Törnblom<mailto:thomas.tornblom@iar.com>: Could you check the porting to IAR toolchain? BR, Tamas Ban

Re: [TF-M] CMake flags

Zephyr uses DT as a means to describe the hardware to the system for things like register address, irq numbers, etc. Instead of the typical runtime usage, it generates code to be used at build time for Cortex-M (and other) devices to address the size cost concern. On the KConfig side Zephyr uses a python implementation of the KConfig parser to allow portability across host build systems. - k > On Jun 12, 2020, at 4:35 AM, Gyorgy Szing via TF-M <tf-m(a)lists.trustedfirmware.org> wrote: > > Hi, > > Just some minor additions.

Re: [TF-M] CMake flags

I think it'd be advantageous to not have a parser for an arbitrary config file format in the cmake, since the cmake set(CACHE) statements are already fairly user-readable. It would be different if we could only generate something less readable from the kconfig (i.e. xml/json). It would be ideal if we could generate the statements such that: set(<variable_name> <default_option> CACHE <TYPE> "<docstring> (<valid_option> | <valid_option> | ...)" I'm not sure if we can do this in Kconfig, but it seems plausible, and imo is the ideal solution since it gives the user of later editing the cmake config (even using a cache editor like ccmake) while documenting which choices are sane.

Re: [TF-M] CMake flags

by Gyorgy Szing

Hi, Just some minor additions. In the TF-M build system Kconfig will most likely generate input for cmake scripts, so the compiler may not have a connection to it. The original intention with DT is capturing configuration data to allow hardware independent binaries (for defining base address of peripherals, boot information, etc..), and is mostly parsed runtime. In the Cortex-M space this might be a bit out-of scope. Most likely it will be used as a "standard" language to define "retargeting" information, and a tool will be developed which runs compile time and which allows access to the retargeting data for cmake. Something like CMSIS zone, but closer to established open-source technologies. In multicore systems having bot Cortex-A and M core DT would allow having a consistent solution for both A and M firmware. This is also a reason why cmake is a better build solution for TF-M than CMSIS Build. /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of David Hu via TF-M Sent: 12 June 2020 11:16 To: Thomas Törnblom <thomas.tornblom(a)iar.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] CMake flags Hi Thomas, DT is another very attractive topic.

Re: [TF-M] Gerrit issues

by Kevin Peng

Hi, In case you meet the same issue as Thomas. There are two possible solutions from our experience. One is: * Abandon both the duplicated changes. * Change the change-ID of you patch and then submit * You end up with a whole new patch without the original histories. In this way, you lose both the change history and review history. If you are OK with that, you can quick solve the issue by yourself. Otherwise, the other solution is to contact Benjamin Copeland <ben.copeland(a)linaro.org<mailto:ben.copeland@linaro.org>> to delete one of the duplicates(usually keep the one with histories).

TF-M URLs update for code and Gerrit review

by Anton Komlev

Hello TF-M code moved to the new location recently with a redirection link from the original URL - for compatibility purpose. Unfortunately, Gerrit got confused with two namespaces and several patches got messed up last week. To prevent it from happen again, the old TF-M location marked as read-only mirror. Please use new TF-M URL for your pushing your commits: ssh://<user-name>@review.trustedfirmware.org:29418/TF-M/trusted-firmware-m New repo URL: https://review.trustedfirmware.org/TF-M/trusted-firmware-m Thanks, Anton

Re: [TF-M] build error

by Gyorgy Szing

Hi, Can you please run the build with "cmake -build ./ -- install VERBOSE=1". This will show compiler command lines which could help. Based on the fact your assembler is complaining not understanding assembly instructions generated by the C compiler, I suspect your compiler is not supported. For "arm-none-eabi-cc -v" I get the following output: ....... gcc version 6.3.1 20170215 (release) [ARM/embedded-6-branch revision 245512] (GNU Tools for ARM Embedded Processors 6-2017-q1-update) (Note I removed some not so interesting lines.) As you can see, the version string includes the release name of "6-2017-q1-update". All gcc binaries built by arm shall have this. Please double check what compiler you are using. The last bullet point in the blue "notes" section here: https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu… has the link to the download site and also names the releases you can use. /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Shawn Shan via TF-M Sent: 04 June 2020 10:21 To: Quach, Brian <brian(a)ti.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] build error Hi Brian, I would like to correct my last Email: * CMSIS_5 version should be v5.5.0. * Mbedtls is not required anymore.

Re: [TF-M] Changes required to enable Zephyr integration as External_Project

Re: [TF-M] TF-M PSA key management

by Soby Mathew

Hi Brian, The struct you have mentioned is part of the implementation defined `psa_key_attributes_t` data structure. The key algorithm and policy are accessed via appropriate get/set API's (like psa_set_key_algorithm/ psa_get_key_algorithm). Hence these fields are not meant to be directly accessed by the clients but are an implementation detail of crypto Service. The only reason the 2 algorithm fields exists now is because the mbedcrypto defined the structure that way. I have a patch in flight which cleans up the client view of the psa_key_attributes_t such that only fields required by client are defined. The patch is available for review here : https://review.trustedfirmware.org/c/trusted-firmware-m/+/4217 Regarding psa_open_key() and psa_close_key(), TF-M tries to implement PSA Crypto 1.0 Beta 3 version of the spec whereas the APIs are removed in 1.0 version. Currently mbedcrypto does not support 1.0 version fully yet. Once 1.0 is supported mbedcrypto, then TF-M will also make the migrate the APIs to 1.0. This is expected to happen during Q3 timeframe.

Re: [TF-M] DSP instructions and FPU use

by Joseph Yiu

Hi Ken, Soby, In additional to FPCCR_S.TS, You should also set FPCCR_S.CLRONRET and FPCCR_S.CLRONRETS. FPCCR_S.CLRONRET ensures that FPU register contents are cleared when return from a Secure exception to the Non-secure world, and FPCCR_S.CLRONRETS ensures that the Non-secure world cannot change the FPCCR_S.CLRONRET setting.

The FPCCR.LSPEN allows saving the context lazily which was what I was referring to previously. Eventhough the hardware is performing the stacking, the policy chosen (lazy stacking/stack always) affects interrupt latency which should be considered for the design for FPU usage in TF-M.

While booting we clear FPCA since we are not using FP under handler mode, we don't want FP get involved during initialization and need extra clean up job. But if a thread uses FP the FPCA is set to 1 automatically, and if exceptions are happening the FP context stacked automatically by hardware - the secure scheduler just keep the EXC_RETURN which contains FP context and finally recover it back. Which means if you enabled hardware FP unintentional it can work, the only place a problem may occur should be the non-secure preempting secure execution case. I think the only thing we are missing now is we did not set FPCCR_S.TS = 1 since we did not realize that user would enable FP in secure world. This would cause the FP register may contain secure information while Non-secure preempting secure execution. Need to go through the settings and double-check. So at least before we finish the estimation I think FPCCR_S.TS should be set to ensure the security. Andrej, have you set this bit while you are using hardware FP?

The easiest way would be to enable FP context stacking for every context switch but it would impact every context switch irrespective of whether FP unit is used in that context or not . I guess this is the approach taken by Andrej ? . The Lazy Floating point state preservation would be better for performance but it would have additional complexity in managing the contexts. Just blue sky thinking here: There could be a middle ground wherein some partitions are allowed to use FP while others are not because they don't really need to. The ones allowed to use FP will need to cater for the additional stack requirement to save FP context. The actual save of the context can be done either on context switch to the partition or lazily. This approach could give the benefit of both performance and memory savings but it requires some analysis and design to be done in TF-M.

Can you do some experiments on enabling hardware float point and see if it is working, and then let's see the patch? That would be helpful for our estimation. During bootup, we cleared the CONTROL.FPCA, and if you access hardware float point in a partition thread should work because it would re-invoke the FPCA bit and make everything work as usual.

About FPU, it seems there is no way to use the hardware floating-point support instead of the software support (see "-msoft-float" flag in CommonConfig.cmake file). Is there a reason for that? Maybe some performance reasons? About DSP, in CompilerGNUARMxy.cmake files, architecture definition is preferred to CPU type and, in my case, "-march=armv8-m.main" flags is chosen (without +dsp option). The solution I found is to only define ARM_CPU_TYPE (and not ARM_CPU_ARCHITECTURE) to use "-mcpu=cortex-m33" flag instead of "-march=armv8-m.main". So I can use DSP instructions. However, I am not sure if this is the best solution. Maybe an option could be added to allow or not the use of DSP instructions? Thank you in advance for the answer, Best regards, Cindy

Hi, Thank you very much for the changes to the image signing script - those look like great QOL improvements. WRT Ninja and externalproject support, there is currently an ongoing effort to improve the TF-M build system by rewriting it to use more modern and streamlined cmake. I haven't tested it as an externalproject yet, but am pretty confident that it should now work "out of the box". When it gets to the stage that it can be submitted to trustedfirmware.org as a patch I'll try to reply to this so you can test that.

Hi, The following task lists some of the changes that we had to make to enable TF-M to be built using ExternalProject_Add from Zephyr, as well as enabling the use of ninja for TF-M builds (which is often significantly faster than using classic makefiles): https://developer.trustedfirmware.org/T760 The ninja changes have been tested with: $ cmake -GNinja -DPROJ_CONFIG=`readlink -f ../configs/ConfigDefault.cmake` -DTARGET_PLATFORM=LPC55S69 -DBL2=False -DCOMPILER=GNUARM .. $ ninja The changes to imgtool.py resolve some platform issues when signing binaries, and add a convenience requirements.txt file that can be run in CI to ensure that all of the Python dependencies are met for this tool. Any concerns or feedback on these are welcome, but I would be interested to hear any opinions on ninja which is often considerably faster out of the box when compiling (at least on Linux and native OS X, which is what I use for my builds). Best regards, Kevin

Re: [TF-M] DSP instructions and FPU use

by Soby Mathew

Hi Ken, I agree that FPCCR_S.TS (in addition to other setting for FP) should be set if FPU needs to be used in secure world. The FPCCR.LSPEN allows saving the context lazily which was what I was referring to previously. Eventhough the hardware is performing the stacking, the policy chosen (lazy stacking/stack always) affects interrupt latency which should be considered for the design for FPU usage in TF-M. Best Regards Soby Mathew From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: 01 June 2020 15:55 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] DSP instructions and FPU use Hi Soby & Andrej, The FP context is managed by hardware automatically in M-profile architecture. While booting we clear FPCA since we are not using FP under handler mode, we don't want FP get involved during initialization and need extra clean up job. But if a thread uses FP the FPCA is set to 1 automatically, and if exceptions are happening the FP context stacked automatically by hardware - the secure scheduler just keep the EXC_RETURN which contains FP context and finally recover it back. Which means if you enabled hardware FP unintentional it can work, the only place a problem may occur should be the non-secure preempting secure execution case. I think the only thing we are missing now is we did not set FPCCR_S.TS = 1 since we did not realize that user would enable FP in secure world. This would cause the FP register may contain secure information while Non-secure preempting secure execution. Need to go through the settings and double-check. So at least before we finish the estimation I think FPCCR_S.TS should be set to ensure the security. Andrej, have you set this bit while you are using hardware FP? Or just let it go (use default TF-M setting)?

Hi, As the first commit of 'source_structure' document is merged, here is the first patch to follow the document: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4315 The patch looks big, even it just adjusts the content inside 'secure_fw'. To make the related sources can pass the building, some files out of the 'secure_fw' need to be changed. The goal of merging is ASAP so that we won't block upcoming features. Please provide the feedback about potential USAGE problem you may meet. As the patch is big, it won't be applicable to make THIS patch perfect to meet all the requirements defined in the document, a series of upcoming patches would come as amending. Also if there are suggestions about the structure document, please write to the mailing list and put discussion in this task: https://developer.trustedfirmware.org/T751 The rendered structure document: https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/252/artifact/bui… BR /Ken

Correction - MMIO region is not sharable between partitions

by Ken Liu

Hi, In the tech forum I mentioned a potential way of sharing MMIO regions - this is not correct. Double checked the PSA FF and it is defined explicitly in the spec page 43: "A Secure Partition always has exclusive access to an MMIO region. Secure Partitions are not allowed to share MMIO regions with other Secure Partitions and MMIO regions are not allowed to overlap." Sorry for the confusion. BR /Ken

Re: [TF-M] Pre-provisioned keys

by Tamas Ban

Hi Brian, The pre-provisioned keys are highly platform dependent. TF-M just provide an API to access them, but currently we have no standard/general solution to storing them. There was question a few weeks ago related to same topic. I just copied Shebu's past answer here: "Provisioning was added as a future roadmap item in anticipation of a PSA Provisioning Specification. The Specification (Factory or application specific) hasn't happened so far. There is no active work ongoing in TF-M around provisioning. TF-M using provisioned keys in CC-312 on MuscaB1 platform is available as an example. See details here<https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu…> under CC312 heading. In TrustedFirmware TSC, provisioning has been a discussion topic sometime back. Search for provisioning in the minutes below. https://github.com/microbuilder/certificate_chains/blob/master/rfc_tfm.md is an RFC that Kevin prepared during those discussions for TF-M devices to use certificate chain.

Simplify the veneers of library model

by Mingyang Sun

Hi all, In the current implementation, every secure function has an associated veneer function. Therefore, there are so many veneer functions in ‘tfm_veneers.c’, which have a similar prototype. This would lead to: * Waste of the veneer and secure function size – these APIs have a similar prototype, and they have unified NS dispatcher already. * More secure functions lead to more veneers and potential re-configuration of the non-secure callable area. This patch tries to unify the service entry so that: * Similar function codes do not need to be duplicated. * Keeping almost the same performance. This is also an experiment patch to start the journey to the SFN model Andrew proposed. Let’s see the feedbacks and decide what to do in the next step. https://review.trustedfirmware.org/c/trusted-firmware-m/+/4115 Please do feedback, especially the library model users – please check what kinds of the inconvenience it brings so that we can discuss the correct shape. Here are some details in the patch: Prototype of the unified veneer function: psa_status_t tfm_sfc_call(uint32_t ctrl, psa_invec *in_vec, psa_outvec *out_vec); where: the uint32_t type parameter ‘ctrl’ is a pack of parameters - psa invec length, psa outvec length, and function identifier. [8 bits for inlen][8 bits for outlen][16 bits for function identifier] This is to avoid the condition that 5 parameters will cause re-wrapping of parameters. Time cost and code size measurement: github-tracking Use the unified veneer cost of a veneer call is 1264 cost of an interrupt is 941 veneer used 832B, region size 832B, 100% cost of a veneer call is 1274 cost of an interrupt is 941 veneer used 64B, region size 832B, 7.69% Thanks, Mingyang

[RFC] Compiler-specific configurations and architecture registers

by Summer Qin

Hi, Even the ongoing HAL design abstracts all platform-specific operations, there are still some operations that need to be performed directly in TF-M, such as architecture-related operations. These operations are common for all platforms, such as: * generic assembler code for AAPCS based context management. * assign attributes to specific functions. These operations rely on compiler and architecture much instead of the platform. So, define a CORE-specific compiler configuration header file would be a straight requirement. With these unified headers, writing the architecture-specific code would be much safer because it won't involve hardcode compiler related changes. The minimal set of mandatory architecture registers is also planned to be defined. Here send out a mail to collect for the feedbacks - is it worthy of doing this to decouple the architecture from the platform, or we can just re-use the platform provided headers? Any comments are welcome:) Best Regards, Summer

Proposal to add sub-folders to collect documents under design_documents folder

by David Hu

Hi all, I'd like to propose to add sub-folders under docs/design_documents to collect the documents on the same topic. Currently, there are already 21 documents in total under docs/design_documents and the number may grow rapidly. It can be more clear if we can organize the documents on the same topic into a dedicated sub-folder under docs/design_documents. Please help review the patch set https://review.trustedfirmware.org/q/topic:%22design-doc-subdir%22+(status:… if the proposal sound interesting. I move dual-cpu and TF-M Profiles related documents to their dedicated folder respectively in the patches. Any comment is welcome! In current patches, the html pages are still put in the same level during Sphinx build. It is because design documents are grouped by document status, instead of document hierarchy. The html pages can be further organized as well if we switch to group html according to folder structures. Best regards, Hu Ziji

[RFC] [Source Structure] Design document is availiable.

by Ken Liu

Hi, There is an upcoming source structure adjustment for TF-M. The basic idea is to make the structure simple and easy to be understood by users. The significant change would be a long term goal so no worry. In the beginning, there would be changes in core and platform to align with HAL changes. Please help to put comments on the design documents - after aligned, this document would be a user guide document to describe the source structure of TF-M. The patch is here: https://review.trustedfirmware.org/c/trusted-firmware-m/+/4112 And the issue link: https://developer.trustedfirmware.org/T751 Feel free to put any comments or ask questions.

TF-M repository restructure

by Anton Komlev

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

Re: [TF-M] Boot seed in TFM Attestation tests

Hi Andrej, The value of boot_seed is compared against a hard coded value. This behaviour can be turned off in test/suites/attestation/attest_token_test_values.h.

Re: [TF-M] Query on persistent keys Crypto API

by Soby Mathew

Hi Kevin > Presumably this positions the merged change request around 1.0 beta 3, just to know where we stand with the API documentation versus implementation in TF-M? Yes, you are right, the Crypto service as implemented in TF-M positions it very close to 1.0 beta 3 API specification. There is still some unimplemented functionality and some differences in error code with respect to the Beta3 specification as reported by the compliance test suite here : https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/docs/t… > Presumably this migration to ID based accesses (versus handles) is still a work in progress, with a goal of perhaps being complete for 1.1? Yes, TF-M depends on mbedcrypto to provide the necessary functionality.

Hopefully the solution suggested by Sherry is good enough for you to progress although your code will need to migrate to the API as specified in v1.0 at sometime in the future when TF-M implements the same.

Re: [TF-M] TF-M Technical Forum call - May 14

by Andrew Thoelke

Hi, Following on from the presentation and discussion on Ken's "Default Handles" proposal on 30 April, we have made some updates following the feedback and further implementation consideration. I (or Ken if he attends) can present an update on the proposal. I also mentioned last time that there is some missing context for this proposal. We are working on an update for PSA-FF-M v1.1 that will provide an enhancement of the v1.0 'IPC model' for secure services, and also a 'Secure Function model' which is similar to the 'library model' of TF-M today. The objective is a single architecture that enables secure service developers to select the framework features required for the complexity of the service; and the framework implementation to be optimised for simple systems. On Thursday, I would like to present an introduction to this PSA-FF-M v1.1 roadmap, and outline the steps that we think are required.

TFM 1.0 integration merged into upcoming Zephyr 2.3

by Kevin Townsend

Hi, Just as a FYI, TF-M 1.0 support was merged into Zephyr RTOS this week, meaning that it will be included by default in Zephyr starting with the upcoming 2.3 release. Zephyr is used on the non-secure side, and TF-M is used on the secure side, with the TF-M build happening as part of the normal Zephyr build process, meaning no knowledge of TF-M internals is required to get started. It's also worth highlighting QEMU integration with Zephyr+TF-M. Using the MPS2 AN521 target, you can run application from the command-line with QEMU, meaning that you can create test applications that use the PSA APIs with no HW required, or perform certain application tests purely in SW. As an example, the following sample was run with a clean install of Zephyr, showing QEMU output and demonstrating how to use the initial attestation, crypo and secure storage services: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/tfm_integr… $ mkdir zephyrtfm && cd zephyrtfm $ west init $ west update $ west build -p -b mps2_an521_nonsecure zephyr/samples/tfm_integration/psa_level_1/ -t run [INF] Starting bootloader [INF] Swap type: none [INF] Swap type: none [INF] Bootloader chainload address offset: 0x80000 [INF] Jumping to the first image slot [Sec Thread] Secure image initializing!

Remove 'INDIVIDUAL_SW_COMPONENTS' support from attestation

by Tamas Ban

Hi, I let you notify that 'INDIVIDUAL_SW_COMPONENTS' support is planned to be removed from attestation service and bootloader. What is this? * Boootloader and SPE can exchange data through shared memory. This is needed to provide the boot status info to attestation service. The boot status info is included in the SW_COMPONENT claim in the attestation token. * Until now two types of data encoding was supported during this data sharing: * All boot status data item is passed as a single TLV entry: -DATTEST_BOOT_INTERFACE=INDIVIDUAL_CLAIMS * Boot status is already encoded to CBOR format at build time. Bootloader only updates a few field in it, and pass the CBOR object to SPE. Then attestation service just include this already CBOR formatted object to the token, without the need to applying further encoding. -DATTEST_BOOT_INTERFACE=CBOR_ENCODED_CLAIMS The 'INDIVIDUAL_CLAIMS' format is marked as deprecated feature for a while in the code base. Now the plan is to remove it and rely fully on the 'CBOR_ENCODED_CLAIMS' format. The build system support for this is present in TF-M for a long, and recently it was upstream to original MCUBoot 'imgtool' script as well. Next MCUBoot release (v1.6) will contain it. If you has any objection, because your project is using the 'INDIVIDUAL_CLAIMS' format then please let us know! BR, Tamas

Re: [TF-M] LPC55S69 support merged into master

by Thomas Törnblom

Hi Kevin, Are there any plans to add ARMCLANG as a build environment for this? If so, then I can add an IAR port as well. Going from ARMCLANG to IAR is much easier than to go from GNUARM to IAR. I have access to one of these boards so will be able to run regression tests as well.

Improve library model secure function entry points

by David Hu

Hi all, I uploaded a patch (https://review.trustedfirmware.org/c/trusted-firmware-m/+/4009) to simplify/improve the entry points of secure functions in Library model. In current Library model implementation, each secure function includes the same inline entry point tfm_core_partition_request(). Actually, only the NS client check is required to be inline. The duplicated entry points cost much code size. Thus this patch extracts NS client check and make it as a simple inline function tfm_core_is_ns_client(). tfm_core_partition_request() becomes a normal function called by each secure function. Some quantitative results of code size optimization (about 3KB) are shown below: Profile Small (ConfigDefaultProfileS) is based on https://review.trustedfirmware.org/q/topic:%22symmetric-attest%22+(status:o… ConfigDefault + Armclang 6.10 + Release + AN521 Code RO-data RW-data ZI-data Current impl 129778 8994 272 50108 Improved 126294 8994 272 50108 ConfigDefaultProfileS + Armclang 6.10 + Release + AN521 Code RO-data RW-data ZI-data Current impl 55886 3274 200 31664 Improved 52930 3274 200 31664 Best regards, Hu Ziji

Although we originally saw this with PSoC64, I was able to reproduce this problem on a Musca-B1. Can you please have a look please? Note that the behavior is not always the same. I have 2x Musca-B1 boards and they both failed the first time I ran the PSA Crypto test suite. However, they both did not freeze on a 2nd run. Possibly a stack issue such that the behavior is dependent on what is in stack. Thank you, Ray This message and any attachments may contain confidential information from Cypress or its subsidiaries.

Re: [TF-M] REGION_DECLARE macros

by Sherry Zhang

Hi Thomas, OK, the problem is caused by that the names of region related symbols that IRA compiler generate are different with those of ARMCLANG. The work around below do can solve the problem. BTW the work around seems not to be a general one. I think another way to solve the problem is adding a macro like SYMBOL_NAME_BASE(region) which is a wrapper of the REGION_NAME on different compilers.

I ran into a lot of these during the IAR port and as I said they don't work with the IAR linker. I work around this in CommonConfig.cmake by this define: --- embedded_set_target_compile_flags(TARGET ${tgt} LANGUAGE C FLAGS ${COMMON_COMPILE_FLAGS} "-DImage$$= " "-DLoad$$LR$$= " "-D$$ZI$$Base=$$Base" "-D$$ZI$$Limit=$$Limit" "-D$$RO$$Base=$$Base" "-D$$RO$$Limit=$$Limit" "-D$$RW$$Base=$$Base" "-D$$RW$$Limit=$$Limit" "-D_DATA$$RW$$Base=_DATA$$Base" "-D_DATA$$RW$$Limit=_DATA$$Limit" "-D_DATA$$ZI$$Base=_DATA$$Base" "-D_DATA$$ZI$$Limit=_DATA$$Limit" "-D_STACK$$ZI$$Base=_STACK$$Base" "-D_STACK$$ZI$$Limit=_STACK$$Limit" --- i.e. I replace $$ZI$$Base with $$Base, Image$$ and Load$$LR are removed entirely, and so on. To make this work I need to split the symbol up into its components, which is done with the REGION macros. So the symbol "Image$$ARM_LIB_STACK_MSP$$ZI$$Base" turns into "ARM_LIB_STACK_MSP$$Base", which is what we use for IAR. For ARMCLANG and GNUARM the macros generate the original symbol.

Re: [TF-M] Questions on TFM_NS_CLIENT_IDENTIFICATION

by David Wang

Hi Reinhard, Add more from user's perspective: The non-secure client id can be used to identify different "clients" from non-secure side. The example from tf-m existing secure service is the storage. Different client id can access different storage space. Therefore, the storage is "isolation" among the clients. The users can create the custom secure service and leverage different client ids (let's say non-secure client id here) to identify different non-secure "callers": * The meaning of identifying different non-secure callers depends on the user case of the secure service. For example, different storage spaces, different access permissions, etc. * In RTOS, different non-secure client ids are managed via TZ_APIs (https://www.keil.com/pack/doc/CMSIS/Core/html/group__context__trustzone__fu…) if they're enabled. * The mapping between non-secure applications and the TZ secure contexts (stand for different client ids in tfm) is managed by NS RTOS kernel. When the ns applications get updated, then the mapping should also be maintained by RTOS kernel. Hope this helps.
