Build failure of release/2.1.x

by Zhang, Hao

Dear whoever that may concern, I am trying to build TF-M with release/2.1.x. The first error I see when cloning mbedcrypto is Cloning into 'mbedcrypto-src'... remote: Enumerating objects: 31188, done. remote: Counting objects: 100% (31188/31188), done. remote: Compressing objects: 100% (15898/15898), done. remote: Total 31188 (delta 24658), reused 20224 (delta 15043), pack-reused 0 (from 0) Receiving objects: 100% (31188/31188), 35.81 MiB | 4.89 MiB/s, done. Resolving deltas: 100% (24658/24658), done. fatal: invalid reference: f985bee CMake Error at mbedcrypto-subbuild/mbedcrypto-populate-prefix/tmp/mbedcrypto-populate-gitclone.cmake:40 (message): Failed to checkout tag: 'f985bee' I therefore change the GIT_SHALLOW to FALSE, and it builds. However, another build error come up when applying patches for mbedcrypto. Checking patch library/psa_crypto.c... Checking patch library/psa_crypto_driver_wrappers.h... error: library/psa_crypto_driver_wrappers.h: No such file or directory Checking patch library/psa_crypto_driver_wrappers_no_static.c... error: library/psa_crypto_driver_wrappers_no_static.c: No such file or directory I did checkout commit f985bee and find in fact there is no psa_crypto_driver_wrappers.h. Is it possible that the commit hash is incorrect? Best regards, Hao

by Takekazu Tabata (Fujitsu)

Dear TF-M Team, I'm Takekazu Tabata, a director and architect from the Fujitsu processor team. We are currently developing FUJITSU-MONAKA, which supports the CCA feature. We have three questions regarding the TF-M documents and TF-M implementations. We would greatly appreciate it if you could provide answers. Question 1) In the TF-M document “RSE provisioning”, The CM provisioning Key is used to encrypt DM Provisioning Bundle. https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_pro… After the cold reset, the RSE will automatically transition to Device Manufacturer provisioning state “DM” as the LCM hardware state-machine reads the values of the cm_config_1 and cm_config_2 fields as non-zero. This state is designed to provision the DM provisioning key, the DM code-encryption key and the DM config. The procedure follows the same steps as the CM provisioning flow, with the exception that the bundle will now be encrypted and signed using the CM provisioning key and must be placed at the base of VM1. However, the purpose of the data provided in the DM is not described in this document. These data are not used in the source code of TF-M v2.2.0. DM provisioning is probably assumed to be done during device manufacturing, but could you explain the purpose in more detail? Also, What are the DM provisioning key, the DM code-encryption key and the DM config used for? Question 2) In the TF-M document “RSE integration guide”, attestation key(CPAK) is derived by GUK. https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_int…<https://trustedfirmware-m.readthedocs.io/en/latest/platform/arm/rse/rse_int…> The GUK is a key unique to a group of chips that have identical security properties, used to derive the attestation key. However, CPAK is derived from HUK in the source code of TF-M. GUK in the specification is a typo. https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m.git…<https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m.git…> /* This derives from HUK, there is a typo in the spec, not from GUK. * FixMe: this should be configurable per platform */ return setup_key_from_derivation(KMU_HW_SLOT_HUK, NULL, iak_seed_label, sizeof(iak_seed_label), NULL, 0, RSE_KMU_SLOT_CPAK_SEED, /* FixMe: The slot needs rename to IAK_SEED */ &aes_key0_export_config, NULL, false, boot_state_config); Which is right, GUK or HUK? If it‘s HUK (not Virtual HUK), is it no problem that multiple CPAKs are generated in Multi-socket systems? Question 3) In the CM/DM lifecycle state, is it no problem to create an original provisioning bundle to run chip or device verification programs in PE? Thank you for your time and assistance. Best regards, TABATA

Broken link in TFO/TF-M entry page

by Etienne CARRIERE

Hello, I've seen that the "CONTRIBUTE/SUBMIT CODE<https://tf-m-user-guide.trustedfirmware.org/contributing/contributing_proce…>" link in https://www.trustedfirmware.org/projects/tf-m/ is broken. It links to deprecated https://tf-m-user-guide.trustedfirmware.org/contributing/contributing_proce… whereas I think it should link to https://trustedfirmware-m.readthedocs.io/en/latest/contributing/contributin….

Order of starting Secure Partitions

by Florek, Bartlomiej

Hello, I'm trying to fit a new Secure Partition into Trusted Firmware - M environment. The current working environment consists of Zephyr RTOS 3.7 + TF-M 2.1.0 running under QEMU on MPS2 AN521 platform. General skeleton is in place - manifest with dependencies on TFM_CRYPTO, interface, IPC and handling communication. However, I have problems with using the PSA Crypto from the aforementioned new Service. I need a hash function, so I thought I'd use PSA Crypto API. The problem is that either the hash function or the initialization function (psa_crypto_init) is returning error (PSA_ERROR_INSUFFICIENT_MEMORY). I discovered that logs show PSA Crypto partition is loading after mine. This problem occurs in the entry_point function. Is it possible to change the order of partitions loading or is there different mechanism advised to synchronize partition loading? Thank you in advance for your suggestions. Best regards, Bartlomiej

Planned outages

by Matthew Dalzell

Hi all, There are some planned outages for Friday morning (30th May UK around 10AM BST) to our CI. This will affect the review process for a short period of time, expected to be less than one hour, but may cause some disruption over the weekend too. I will be sure to send out another message once things have settled and should be back to normal. Thank you for your patience and apologies in advance for any issues which may arise, Matt

Issue building docs

by Bohdan.Hunko＠infineon.com

Hi all, I am trying to build docs with following commands: cmake -S docs -B ./build_docs cmake --build build_docs/ -- tfm_docs_userguide_pdf But I get following error resolving references... failed Warning, treated as error: RSVG converter command 'rsvg-convert' cannot be run. Check the rsvg_converter_bin setting When I remove -W (warnings are errors) option from COMMAND "${SPHINX_EXECUTABLE}" -W -b html -j 1 -c ${SPHINXCFG_CONFIG_PATH} ${SPHINXCFG_SOURCE_PATH} "${SPHINXCFG_OUTPUT_PATH}/html" In docs/CMakeLists.txt then docs builds fine. Is this -W option intentional? Should this issue be fixed or -W removed?
