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] Project Maintenance Proposal for tf.org Projects

by Sandrine Bailleux

Hi all, I've received very little feedback on version 2 of the proposal, which hints that we are reaching an agreement. Thus, I plan to finalize the proposal this week. This can then become part of our development flow for all trustedfirmware.org projects. Thanks again for all the inputs! Regards, Sandrine Bailleux

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

Re: [TF-M] PSA Crypto failure with addition of persistent keys

by Vinay Kumar Kotegowder

Hi Raymond, There are some changes required for PSoC64 target with the recent changes from Jamie on persistent key support for test_c050 (api-tests/dev_apis/crypto/test_c050). I will be pushing changes to GitHub today. You could try them and let us know if you are still facing problem.

Best regards, Hu Ziji From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Raymond Ngun via TF-M Sent: Monday, April 27, 2020 10:26 AM To: tf-m(a)lists.trustedfirmware.org; Jamie Fox <Jamie.Fox(a)arm.com> Subject: [TF-M] PSA Crypto failure with addition of persistent keys Hi Jamie, With the addition of persistent key support, we have seen the PSA Crypto test hang at test 250. 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.
