I've been trying to find out where the tf-m payload is supposed to be stored at. In tfm_secure_boot.rst I see a memory map for the AN521, but where do find this for the Musca A, which I'm using? /Thomas

Rust implementation of the Armv8-M Security Extension

by Nicolas Stalder

Hi My company SoloKeys produces open source FIDO2 security tokens (USB + NFC), and we're in the process of a) moving to a Cortex-M33 microcontroller, and b) an implementation in Rust. This is mostly to say that we're very interested in the security extensions [1] landing in LLVM, so embedded Rust can eventually use them, I understand Hugues de Valon from Arm has done some exploratory work on this. What is the status of this upstreaming process, are there any road blocks, and is there any ETA on public availability? Regards, Nicolas Stalder SoloKeys [1] http://lists.llvm.org/pipermail/llvm-dev/2019-March/131358.html

Removing legacy veneer support from TF-M library model

by Mate Toth-Pal

Hi All, I'm planning to remove the custom veneer support for Library model from TF-M. Please see the proposed patch here: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1597/ Ticket for the change is: https://developer.trustedfirmware.org/T439 After this change all secure services must use the automatically generated veneer functions in 'interface/include/tfm_veneers.h', as it is described in the design: https://developer.trustedfirmware.org/w/tf_m/design/uniform_secure_service_… This change doesn't affect the NSPM secure functions ('TZ_.*()' and 'tfm_register_client_id()' ). This change also doesn't affect IPC model at all (i.e. psa api functions). Regards, Mate

[RFC] RE: Build system changes for dual core platforms

by Ken Liu (Arm Technology China)

Hi, These patches are based on an old patch: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1686 and the task: https://developer.trustedfirmware.org/T199 The existing idea is, app needs v8m veneer to go on the building, so make 'secure_fw' as sub-project of 'app'. While Dual-core is involved, this hierarchy does not make sense. 'secure_fw' should be a standalone sub-project of 'tfm' instead of 'app'. This would benefit the coming build configuration changes. This patch has been put in master branch for quite a while and now call for review again, since in feature branch it has been merged and verified for quite a long time. Thanks. /Ken > -----Original Message----- > From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Andrei > Narkevitch via TF-M > Sent: Thursday, August 15, 2019 2:59 AM > To: tf-m(a)lists.trustedfirmware.org > Subject: [TF-M] Build system changes for dual core platforms > > Hi, > > Please review the proposed build system changes.

Re: [TF-M] Debugger setup for MPS2+ AN521

by Jamie Fox

Hi Kevin, I don't know much about JLink so cannot help with setup, but there is a quick workaround if reset does not work: insert a "B ." instruction on the first line of the reset handler in the startup file. Then the target will sit in an infinite loop while you connect with the debugger, and afterwards you can use the debugger to increment the PC by two to step over the instruction. The typical debug setup in the TF-M team is to use either a Keil ULINKpro or Arm DSTREAM debugger with Arm Development Studio or Keil uVision. Most issues can be debugged on the FVP too, which runs a debug server when the "-S" option is passed.

Re: [TF-M] [RFC] Code restructure of core/spm

Hi, The first patch for moving header files is ready at: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1561 Comments are welcome. I had thought to push patches together but looks like it would block other patches for a while to show a neat merged list, so I would push them one by one.

Linker file changes for multi-core

by Christopher Brand

Please take a look at the patches I've put together to the linker files for multi-core. The fundamental issue that necessitates this change is that the ARMv6/v7 MPU is quite constrained in terms of configuration - the size has to be an exact power of 2, and the base address has to be aligned to the size. This means that we need to group data together in memory so that we can minimize the gaps that we have to introduce to meet the MPU* requirements. To that end, I've grouped all the privileged data together and grouped all the unprivileged data together, and introduced a new #define, S_DATA_UNPRIV_START, that (optionally, in multi-core only) allows the start address of the unprivileged secure data to be specified. This then enables configuring a single MPU region to cover all the unprivileged secure data. Note that only data sections are affected - code is left alone (mostly because the PSoC6 platform has so little Flash that we can't afford any padding at all). https://review.trustedfirmware.org/c/trusted-firmware-m/+/1731 groups the privileged data separate from the unprivileged https://review.trustedfirmware.org/c/trusted-firmware-m/+/1732 adds support for S_DATA_UNPRIV_START Thanks, Chris * In this email I've said "MPU". Technically it's the "SMPU (System Memory Protection Unit) on PSoC6, but that has the same limitations as the ARMv6 MPU.

Build system changes for dual core platforms

by Andrei Narkevitch

Hi, Please review the proposed build system changes. Intention of those is to lay groundwork for building TFM for dual core platforms (aka twincpu). The main problem of the existing build system is that it assumes that both tfm_s and tfm_ns run on the same core. In dual core systems secure and non-secure code runs on two independent cores. Each CPU core can be different in terms of architecture, configuration etc, and this adds the requirement of separating out secure and non-secure builds.. The patches basically do the following: * Introduce TFM_MULTI_CORE_TOPOLOGY, that distinguish single core and multicore builds. * Split secure and non-secure builds and build both in single building execution. https://review.trustedfirmware.org/c/trusted-firmware-m/+/1747 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1748 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1749 Thanks, Andrei This message and any attachments may contain confidential information from Cypress or its subsidiaries.

Re: [TF-M] tfm_core_irq_signals array

by Miklos Balint

Hi Thomas, The first variable in a tfm_core_irq_signal_data_t structure is a partition_id. ID 0 is reserved and cannot be a valid entry in this array so it could, in theory, be checked for terminating the loop. I would argue, however, that having a compile time constant loop count variable is better from a performance and optimization point of view. If loop count is const 0 an optimizing compiler can eliminate the loop altogether while if the iteration count depends on the value of an entry in the array, it would be more unlikely to eliminate the unused loop. The key metrics that TF-M is currently measured against are memory footprint and to a lesser degree latency, and having the extra element in the array and the extra iteration in the loop are both sub-optimal in this respect. I do understand the need, however, to keep the constructs standard C and eliminate deviations. Those can lead to build errors or worse: unexpected runtime behaviour with a simple change in a compiler version or similar, so having a clean, standard, predictable code is essential. So thank you for your effort and yes, until and unless we find a more optimal way to get around this problem, please do introduce the proposed change, taking into possible consideration my first comment on helping the compiler detect the unused code.

Re: [TF-M] gcc linker script help

by Miklos Balint

Hi Chris, Please note that the master branch does support level 2 isolation, so the grouping of sections according to trust domains is already present both for gcc and armclang there. I suggest to refer to that implementation and work from that instead of re-doing it from scratch to avoid unnecessary bifurcation of linker scripts and scatter files for the two platform types. Isolation level 2 readiness was a non-trivial piece of work executed in Q2 so I'd hope that effort can be reused in the twincpu branch.

Debugger setup for MPS2+ AN521

by Kevin Townsend

tl;dr: unable to connect to MPS2+ AN521 with JLink and perform a soft reset to halt at NSPE init, and debug an init issue. Connect via SWD fails, connect via JTAG seems OK, but soft reset requests consistently fail, preventing meaningful debug/trace of the code. Looking for advice on known-good debug setup with GDB and Linux. Full explanation follows: I'm currently working on an application with the following setup: - TF-M (latest) running in the secure processing environment - Zephyr running in the NSPE - PSA FF APIs to communicate between PEs I've run into a HW problem with the UART peripheral that I need to debug, but using a J-Link has been problematic, and I was curious if anyone else has had any success with GDB or JLinkExe and the MPS2+. To debug, I currently do the following: - Copy a valid TF-M + Zephyr and BL2 image to the MPS2+ - Physically reset the MPS2+ (AN521) - Wait for the image to start up (based on serial output) - Connect the debugger - Attempt to reset I get the following output at connect (entering the 'connect' command at the J-Link prompt): NOTE: I've been unable to get SWD to work, and had to fall back to JTAG for the interface. ---------------------------------------- $ JLinkExe -device Cortex-M33 -if jtag -speed auto SEGGER J-Link Commander V6.44i (Compiled May 17 2019 17:38:03) DLL version V6.44i, compiled May 17 2019 17:37:52 Connecting to J-Link via USB...O.K.

Re: [TF-M] independent device driver model working along side SPM

by Miklos Balint

Hi Manoj, Please elaborate on the problem you are seeing and the steps you want to take so we can consider if it's something TF-M is in the process of addressing or if it is out of scope. On first read I feel there's a contradiction: The point of having TF-M - or any secure "supervising entity" - in the system is that it has awareness of the goings-on in the system, understands the states of parallel contexts that are supported by the hardware, to control its security aspects. Having a device driver "not plugged in TF-M" would, on the face of it, defeat the purpose of TF-M as a management entity, and the device driver would need not only to handle its own threat vectors, but any potential collisions with TF-M's understanding and control of the system state, making it, in effect, part of the management entity. So rather than the driver being not plugged in, I guess what we need to work out is how TF-M can be extended to cover the type of use case you are working on, without compromising the holistic security model that TF-M implements - but there's no one-size-fits-all solution.

I do not want to plug my driver in TF-M due to latency considerations. Basically my plan is to introduce non secure callable veneers for calling the interfaces of the driver which I am introducing. Any thoughts on this will be helpful. Regards Manoj -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-m

Re: [TF-M] Changes to CI for python dependencies

by Minos Galanakis

The CI comprises of three modules. The Jenkins logic, the Python Scripts and the docker build slave. The environment is provided by the docker build slave and provisioned into the pipeline flow when the venv is created for each stage: virtualenv -p python3 ${VENV_P3_NAME} --system-site-packages No requirements are installed at the Jenkins Stage, but if needed as an one-off (i.e. for staging purposes), the design supports it. The case for installing Python requirements on the fly using requirements.txt Extending requirements dynamically on the fly, can be quite a challenge due to the way Jenkins handles the absolute resolution of workspace directory on each step. In short Python’s virtual-environment stores the configuration paths in absolute format, while Jenkins is not guaranteed to give you the same reference to a working directory in consecutive calls in the pipeline. So if you create a venv at stage 1, which evaluates ~/ as /server/workspace/fubar-job/venv/.. and then attempt to call it in a following parallel step, the code may be located at /server/workspace/1/fubar-job/venv At this point you can either create the VENV in each stage, and reinstall the requirements, effectively wasting bandwidth or hack it by piping everything in SED before activating to ensure the path is resolved correctly. For that purposes the ci-scripts level requirements.txt will be deprecated in the next feature update. How should a user access or modify the TF-M Build environment. Environment will be established at the docker build stage. https://review.trustedfirmware.org/admin/repos/ci/dockerfiles And more specifically the requirements for Python3 in this file: https://git.trustedfirmware.org/ci/dockerfiles.git/tree/xenial-amd64-tf-m-b… After it has been updated and merged you should raise a ticket and request the image to get rebuilt, or if it is not very critical, wait for some other party change to trigger the build. The process requires creating local docker image, meant to test your changes but also allowing you to access the TF-M build environment as deployed on the CI. You can do that following the steps below: # Get the docker image $ git clone https://review.trustedfirmware.org/ci/dockerfiles && cd dockerfiles/xenial-amd64-tf-m-build # Edit the entry point to convert it not to be a jenkins-slave $ vi Dockerfile # change ENTRYPOINT ["/usr/local/bin/jenkins-slave"] to ENTRYPOINT [/bin/bash"], save exit # Build the image $ docker build ./ # Find the image hash id $ docker image ls # Run an interactive bash shell, mounting a local directory as /opt/openci in instance (if required to share files) $ docker run -it --name tf-m-build-env -v /YOUR_CUSTOM_PATH:/opt/openci 10bcb173cd39 # You can relaunch that instance in the future by starting it again. $ docker start && docker -exec -it tf-m-build-env /bin/bash Please let me know if you need more clarity or guidance on how to handle modifications on the CI.

Re: [TF-M] PSA Storage API

by Jamie Fox

Hi Andrej, Alignment with the PSA 1.0.0 APIs is on the TF-M roadmap for next quarter: https://developer.trustedfirmware.org/w/tf_m/planning/ The "release" branch of the psa-arch-tests repo should be used for functional API certification. TF-M is compatible with that branch.
