TF-M version reporting issue

by Anton Komlev

Hello, We've identified an issue with the TF-M versioning: it reports the wrong version from Git tags (showing v2.1.3 instead of the correct v2.2.1). As a temporary workaround, please set the version manually. We're working on a fix and will share updates as soon as possible. Best regards, Anton Komlev

Update: TF-M now uses Python packaging for modules and scripts

by Mudit Sharma

Hi all, TF-M has recently introduced Python packaging for its modules and scripts. If you’re building the latest TF-M mainline, you’ll need to install them by running the following command from the root of the TF-M repository (using a virtual environment is recommended): ``` pip install . ``` or ``` # `-e` installs modules and scripts in editable/development mode i.e. source edits are automatically reflected in your dev environment pip install -e . ``` NOTE: You'll have to re-run the above command every time a new module is added, module is renamed or a new dependency is added. The documentation [1] has been updated with more details. In addition, new guidelines are now available [2] for adding new scripts and modules. Thank you. Best regards, Mudit Sharma [1]: https://trustedfirmware-m.readthedocs.io/en/latest/getting_started/index.ht… [2]: https://trustedfirmware-m.readthedocs.io/en/latest/contributing/python_scri…

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

Clarification on IRQ Preemption of Secure User Context by Non-Secure Interrupts

by Waqar Ali Tahir

Dear TF-M Community, I have a question regarding a specific use case involving interrupt handling and domain preemption in a TrustZone-enabled system using TF-M. In the scenario where the processor is executing within a Secure user context (e.g., during Secure Partition execution), is it possible for an interrupt assigned to the Non-Secure domain to pre-empt this Secure execution? * Does TF-M support such preemption by default? * If not supported out-of-the-box, what modifications or configuration changes would be required within TF-M to enable this behavior? Any guidance on how TF-M manages interrupt priority and security attribution in this context would be greatly appreciated.
