Re: [TF-M] Whether the codes in platform folder of tf-m project can be allowed to call secure services in secure_fw folder?

by Raef Coles

Hey Poppy Along with all the good advice from Kevin, I wanted to highlight a couple of things: * There is an example of this already being done in TF-M. The nv-seed code calls into ITS depite being in the platform layer. This code isn't widely enabled, but works fine. (see platform/ext/common/template/crypto_nv_seed.c) * One nuance is when you're calling into the SP. Under library mode, it's not possible to call into another secure partition from a secure partitions's init code. It's possible to do this under IPC mode however. This is likely to cause problems with your usecase, as it seems likely you'd want to load cryptographic keys into the crypto partition during init. On another note - we're currently looking into tidying up our OTP support and creating some sort of basic provisioning workflow (which would also replace the current CryptoCell-312 provisioning code). Our design seems to be similar to yours (Either storing the provisioned data in real OTP or internal flash depending on platform support). This is currently still in progress, but we hope to get patches on the trustedfirmware.org gerrit soon.

Hi Poppy, As you said, how to read the provisioned information varies from platforms. So I cannot comment on how is your approach. But I can give something from the Framework’s point of view.

Re: [TF-M] Questions on Musca-B1 SE implementation - code size analysis

Hi Suresh/Raef, There is no problem in evaluating and reviewing fixes and optimisations to the CC runtime hosted in TF-M. I will have a look into this and sync up with @Raef Coles as well regarding the possible solution that he mentions below. Thanks, Antonio -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Raef Coles via TF-M Sent: Tuesday, July 6, 2021 5:15 PM To: David Hu <David.Hu(a)arm.com>; Mark Horvath <Mark.Horvath(a)arm.com>; Suresh.Marisetty(a)infineon.com Cc: nd <nd(a)arm.com>; tf-m(a)lists.trustedfirmware.org Subject: Re: [TF-M] Questions on Musca-B1 SE implementation - code size analysis Hey Suresh I've had a look into this, and it seems to be a limitation of the cryptocell runtime library. Profile medium enables MBEDTLS_ECDSA_C, which then causes cryptocell's accelerator config to set MBEDTLS_ECDSA_VERIFY_ALT, which are both working as expected. The problem is that the runtime library doesn't use the MBEDTLS_ECP_DP_SECP521R1_ENABLED define (or any other define) to conditionally enable function pointers in the lists used for selecting ECC functions (see cc_ecpki_info.c), so the linker cant optimize those functions out of the final image. Actually fixing this issue probably isn't too much of a problem, but there is an underlying problem that currently the runtime library is effectively unmaintained, and I'm not sure that TF-M can commit to fixing all of the issues in it.

Re: [TF-M] Questions on Musca-B1 SE implementation - code size analysis

by Raef Coles

Hey Suresh I've had a look into this, and it seems to be a limitation of the cryptocell runtime library. Profile medium enables MBEDTLS_ECDSA_C, which then causes cryptocell's accelerator config to set MBEDTLS_ECDSA_VERIFY_ALT, which are both working as expected. The problem is that the runtime library doesn't use the MBEDTLS_ECP_DP_SECP521R1_ENABLED define (or any other define) to conditionally enable function pointers in the lists used for selecting ECC functions (see cc_ecpki_info.c), so the linker cant optimize those functions out of the final image. Actually fixing this issue probably isn't too much of a problem, but there is an underlying problem that currently the runtime library is effectively unmaintained, and I'm not sure that TF-M can commit to fixing all of the issues in it.

However, the CC312 components appears to be generating libraries that are disabled in mbedcrypto. One such example is the object file: cc_ecpki_domain_secp521r1.o generated for medium profile. Wondering if this is expected or just an overlooked escape.

Please check t Profile Medium and Profile Large design documents below. The ciphers supported are listed in the document. Profile Medium: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/profi… Profile Large: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/profi… 1. I don’t think the software countermeasures against physical attacks are enabled in Musca-B1 SE, by default. Mark, please correct me if I misunderstand it. TF-M implements a Fault Inject Hardening (FIH) library as software countermeasure to mitigate physical attacks. FIH is enabled as Medium Profile in Profile Large by default. You can set `TFM_FIH_PROFILE` as OFF to disable FIH features. FIH is not implemented by mebd TLS or CC312. It consists of protections of TF-M SPM critical routine and platform specific isolation configuration. Please check FIH design document: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/tfm_p… Compared to Profile Medium, Profile Large enables more cryptographic algorithms support and FIH library. It may also include more configurations of higher isolation.

Re: [TF-M] How to build psa-arch-tests to debug mode with debug symbols

by Summer Qin

Hi Matt, Do you want to just build psa-arch tests alone? I check the psa-arch-tests build command documentation (api-tests/dev_apis/README.md), it doesn't mention '-DCMAKE_BUILD_TYPE'. Usually, we build it from TF-M side. It has debug symbols if you build from TF-M with '-DCMAKE_BUILD_TYPE=Debug'. Also, you can build debug variant through the DS-5 environment. It also works.

[Doc]Update sphinx to 2.0.1

by Summer Qin

Hi, To better maintain tf-m documentation, we plan to enable 'turn warnings into errors' in documentation HTML generation. The patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/10424> is on review now. One note is that sphinx should be updated to 2.0.1, otherwise there will be some 'duplicate label' warnings, which will fail documentation generation. Best Regards, Summer

Re: [TF-M] Static check framework for TF-M

by Gyorgy Szing

Hi, Please consider separating the configuration files from the scripts/tools. That would enable re-using the scripts in other projects. I.e. if the .clang-format file lives in the tf-m repo, then the script running clang-format could be used with multiple repositories. /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Salome Thirot via TF-M Sent: 28 June 2021 11:42 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Static check framework for TF-M Hi all, Hugo L'Hostis and I have written a series of patches to enable various checks that can be done locally before committing the code, they will be added in the tf-m-tools repository.

Hi Matt, Thanks for your nice feedback! Yes, your understanding is correct. We had discussed this issue in mbedtls github, you can refer the details here<https://github.com/ARMmbed/mbed-crypto/issues/175>. We also feedback it to psa arch test team, hope they can fix it soon.

Re: [TF-M] Deprecate 'partitions/audit_logging' and its related tests

by Reed Hinkel

Hello Team: Audit Logging is a requirement for a number of e2e security schemes including Microsoft Azure. The implementation may need a bit of use case specific or customer steering to get back on track to demonstrating it will fit the bill for e2e usage. I would think carefully about the strategy here because I fully expect that the moment it is deprecated a business need for it to exist will be raised. Please carefully consider how to add support back in quickly if it is deprecated now, though I would personally like to see it retained. All the best! Reed From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> on behalf of Andrej Butok via TF-M <tf-m(a)lists.trustedfirmware.org> Reply-To: Andrej Butok <andrey.butok(a)nxp.com> Date: Wednesday, June 16, 2021 at 5:56 AM To: Ken Liu <Ken.Liu(a)arm.com> Cc: "tf-m(a)lists.trustedfirmware.org" <tf-m(a)lists.trustedfirmware.org> Subject: Re: [TF-M] Deprecate 'partitions/audit_logging' and its related tests Hi Ken > Or any doubts about depreciating it? It is not used because its implementation is not finished, the current implementation is only for PSA L1 and not supported by IPC. This is not enough for certification. The Log service is optimally required by the PSA Certification. If you going to deprecate it, first delete the requirement from the PSA L2&L3 Certification profiles. Thanks, Andrej From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: Wednesday, June 16, 2021 10:46 AM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] Deprecate 'partitions/audit_logging' and its related tests Hi, The component name under this folder is ‘Audit logging’, and: * There is no explicit specification or requirements for it, and its functionality is as a simple log collector (and looks no one is using it). * It supported under the library model only. And it is meaningless to move to IPC because of this. * It costs extra maintenance effort in test cases and partition code. So a plan is to deprecate this folder and its related test cases; will create a new one when the specification or requirements are explicitly defined. Question here is: Anyone is using this service? Or any doubts about depreciating it? Will collect the response and broadcast it at 25th Jun. Thanks. /Ken
