Re: [TF-M] including platform specific interrupt definitions

by Mate Toth-Pal

Hi Alan, I'm not sure on what version of TF-M is your base. This part of TF-M changed recently. https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1354/ This change introduced the generated manifest header files. For each partition a header file is generated, which contains the signals for the partition. Both IRQ signals, and normal signals in case of IPC mode. Up to the following change all the signals (except for IRQ) had to be defined manually in a header file tfm_spm_signal_defs.h. This replaces the manually created IPC model signal definitions to the generated signals: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1356/ This does the same to the IRQ signals (up until this change, IRQ signals had to be defined in tfm_irq_signal_defs.h): https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1589/ This, and the related changes remove the manually created signal files. https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1382/ So depending on your base you either need to manually define the signals, or should have it automatically once the generator script is run. As a general advice I would suggest to look at the IRQ signal 'SPM_CORE_IRQ_TEST_1_SIGNAL_TIMER_0_IRQ' which is the IRQ signal for one of the test services, and see where it appears and compare it to yours. Also if you could publish some of your code in the gerrit, we might be able help to find out what is the problem.

Re: [TF-M] Missing veneer function implementations

by Kevin Townsend

Hi Mate, I was able to get this working by changing the build config to a non-IPC setup (ConfigDefault.cmake), in which case the tfm veneers functions are available and I can call the PSA API shims directly: SYMBOL TABLE: 100efc80 g F *ABS* 00000008 tfm_tfm_crypto_generate_random_veneer 100efc88 g F *ABS* 00000008 tfm_tfm_crypto_get_generator_capacity_veneer ... Thanks for the clarification. Calling `psa_generate_random` from the NSPE works are expected now.

Re: [TF-M] Missing veneer function implementations

by Mate Toth-Pal

Hi Kevin, Based on what you write your build is probably OK. To access the psa_generate_random service, you need to call the function 'psa_status_t psa_generate_random(uint8_t *output, size_t output_size)', declared in interface/include/psa/crypto.h. in case the TFM/PSA APIs are in use (your case), the transition to the secure code is done through the tfm_psa_* veneers. A service (for example psa_generate_random) is connected with a call to 'psa_connect(...)', which is provided with the ID of the selected service, and then 'psa_call(...)' is called with the handle received from 'psa_connect(...)' (as it is described in the PSA FF Specification). However this exchange is implemented inside the TF-M's crypto API implementation in interface\src\tfm_crypto_api.c, so you only need to call the API function. The veneer 'tfm_tfm_crypto_generate_random_veneer' is compiled into TF-M when the Library model is used. In this case the secure services can be accessed with a single function call, and the tfm_psa_* veneers are not available. However please note, that even in this case you can use TF-M's crypto API, which will call the service the correct way. (Look for the conditionally compiled blocks depending on the TFM_PSA_API macro in the API implementation.) I hope this answers your questions.

Missing veneer function implementations

by Kevin Townsend

Greetings, I'm trying to get the TFM/PSA APIs working in Zephyr, based on the upstream TF-M repository. The libraries are being built with the following settings, followed by make and make install: cmake -G\"Unix Makefiles\" -DPROJ_CONFIG=`readlink -f ../ConfigRegressionIPC.cmake` -DTARGET_PLATFORM=AN521 -DCOMPILER=GNUARM ../ *ConfigRegressionIPC is used simply to include the test service for debugging purposes for now.

Re: [TF-M] Old Mbed-Crypto library?

Hi Andrej, TF-M Crypto has moved to use the same API as the latest available *release* of Mbed Crypto which is Mbed Crypto 1.0.0 . Mbed Crypto is a reference implementation of the PSA Crypto API, which are under active development. TF-M Crypto will align to newest release of Mbed Crypto when they will become available; these new releases will incorporate the new features which are developed as part of the PSA Crypto API, and there will be cases where the new features will break legacy code (i.e. API changes). Regarding the change that you mention, i.e. psa_key_slot_t vs psa_key_handle_t . The concept of psa_key_handle_t that TF-M Crypto is using now is indeed a newer (updated) concept introduced with later versions of the PSA Crypto API to replace the outdated concept of psa_key_slot_t. For example, if you look at the current latest development version of the PSA Crypto API, you will see that psa_key_handle_t is used to handle keys. This is an example of a breaking change in the API that has been introduced by newer releases of the PSA Crypto API. You are right, this change will break regression / PSA API compliance tests, in fact as part of the latest set of patches you can see that the Regression tests are upgraded to use the new concept of psa_key_handle_t instead of psa_key_slot_t. From these updated tests, you can get an idea of how to use the psa_key_handle_t. After this update, TF-M Crypto can't support the PSA API compliance tests (ACK) which were run previously (i.e. the ew_beta0 branch). The psa-arch-test team is in the process of providing an update on the master branch which will enable TF-M Crypto to run compliance tests from there. This should happen in the next couple of weeks. Please let me know in case you need any more clarification.

Hi, This is a design document change for IPC, the intention is to change design document from wiki page to rst format. The patch is put at: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1533 The plan is to put this design document under source control and the following feature changes and enhancement about IPC will be pushed as patches on it - which helps review. Since the original text is already public so I changed the doc status to 'Detailed', plan is to merge it soon with some quick comment. If you think some necessary points are missing please leave comments in this mailing thread and we will add them later with a new patch. Thanks. -Ken
