Various issues in successfully using GDB to debug secure apps on Musca S1 connected over USB DAPLink to a Linux host

by Arun D

Now sure where exactly this belongs, but I already posted question abut the Musca S1 earlier, and this seems relevant. ARM support essentially seem to tell me that they cannot support GDB and they are not certain of DAPLink, and recommend ULINKPLUS debugger with ARM IDE. So wanted to get a sense from anyone who has attempted to use this. In the following I describe the steps to obtain a base line, then provide description in what way GDB / DAPLink seems to misbehave. To get a base line: ~~~~~~~~~~~~~ - I build 'samples/hello_world' app using Zephyr 'v3.4.0'. Copy the 'build/zephyr/zephyr.hex' file to '/media/user/MUSCA_S1' directory when the board is USB. Connect a terminal emulator to the UART exposed by USB DAPLink, e.g. 'picocom -b 115200 -y n /dev/ttyACM0'. I can see on the console the followinbg *** Booting Zephyr OS build zephyr-v3.4.0 *** Hello World! musca_s1 If I press the reset button, the app restarts as well. This is as expected. I note that this is entirely running as in secure mode, that it does not use TF-M. - Next I start 'pyocd-gdbserver'. Then start a GDB session using the 'zephyr.elf' file, 'target remote localhost:3333' to connect it to the gdbserver. It connects ok. So I put a breakpoint at "main", do a 'monitor reset halt', and then continue. The breakpoint at 'main' is hit, I can obtain the backtrace to see it is correct as expected. So my setup seems good. Next I attempt to test a non-secure app with TF-M. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Build the app using Zephyr build env 'west build -b v2m_musca_s1_ns samples/tfm_integration/tfm_psa_test/ -DCONFIG_TFM_PSA_TEST_CRYPTO=y'. Copy 'build/zephyr/tfm_merged.hex' to '/media/user/MUSCA_S1'. Connect a terminal emulator, picocom, to the console, and hit the PBON (power on) button. I see the following output as expected on the console: Musca-S1 Dual Firmware Version 1.9 [WRN] This device was provisioned with dummy keys. This device is NOT SECURE [Sec Thread] Secure image initializing! Booting TF-M 79a6115d3 [INF][Crypto] Initialising HW accelerator... complete. *** Booting Zephyr OS build zephyr-v3.4.0 *** ***** PSA Architecture Test Suite - Version 1.4 ***** Running.. Crypto Suite ****************************************** TEST: 201 | DESCRIPTION: Testing crypto key management APIs | UT: psa_crypto_init [Info] Executing tests from non-secure This is as expected. However, if I press the reset button the board does not appear to reset - this is unexpected. Has anyone seen a different behavior? Is the specific board that I have is misbehaving? - Now I start PyOCD GDB server, start GDB and successfully connect it to the GDB server. The target is halted where it was executing, e.g. Remote debugging using localhost:3333 CC_HalWaitInterruptRND (data=data@entry=1024) at /home/zephyr/zephyrproject/modules/tee/tf-m/trusted-firmware-m/lib/ext/cryptocell-312-runtime/host/src/hal/cc3x/cc_hal.c:107 107 irr = CC_HAL_READ_REGISTER(CC_REG_OFFSET(HOST_RGF, HOST_IRR)); (gdb) This is as expected. - Next I put a breakpoint at 'sprt_main', then issue a 'monitor reset halt', then issue a 'continue', The breakpoint is is NOT hit. I see a blue LED blink at perhaps 4 times per second. This is unexpected. Has anyone seen this behave correctly? Do I have a board that is misbehaving?

Building TF-M for ARM reference SoC/boards MPS2/MPS3 and Musca S1

by capablegh＠gmail.com

Hello. The ARM MPS2/MPS3 have Cortex M33 two processor configuration. I am building TF-M under the Zephyr OS setup. From the build it appears that the secure (TF-M) and non-secure (Zephyr OS and app) are bound and executed on separate CPUs. Assuming that two CPUs are used, in the build, is there a way to force using same one CPU for TF-M and Zephyr/app, while disabling the second CPU? Thanks.

Increasing the flash partition for the Secure Firmware in TF-M for MPS2-AN521 board emulated using Qemu

by Gowri Ramshankar

Problem: ARoT app is too large, that the image build fails. Error: /home/gramshan/zephyr-sdk-0.16.1/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld: bin/tfm_s.axf section `.ER_UNPRIV_CODE' will not fit in region `FLASH' /home/gramshan/zephyr-sdk-0.16.1/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld: region `FLASH' overflowed by 114956 bytes Memory region Used Size Region Size %age Used FLASH: 572684 B 447 KB 125.11% RAM: 54556 B 1 MB 5.20% To overcome this issue, I changed the flash_layout header file (https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/master/platfo…) such that the secure side size is (FLASH_S_PARTITION_SIZE) 700+KB from the 512KB default for the MPS2 AN521 app, and correspondingly update the non-secure side FLASH_NS_PARTITION_SIZEto be 300KB. This builds the tfm_merged.hex file, But fails it to boot the app. So, I do not use your ARoT, but just built as non-secure app - the 'hello_world' Zephyr app that prints a one line hello_world on the console, but using the modified partition layout. This too fails to boot, in that the "hello world" is not printed. I debugged this to find that it is BL2 that is failing. I see that the Panic occurs during the image swapping operation, this is because the image to be filled in the primary slot is identified as invalid and the secure boot stops. The TF-M thinks some firmware upgrade is happening, the integrity check fails and panics, thus inducing a Fault Injection Hardening defense. Now I am stuck with this issue and I do not know how to proceed further, any help on how to change the flash partition sizes in a clean manner would be appreciated.

Scheduling bug

by Bohdan.Hunko＠infineon.com

Hi There seem to be scheduling bug we have found in SPM. This bug is related to handling of interrupts that arrives during SVC call and assert signed for partition. Steps to reproduce: 1. Call psa_wait() from partition (e.g. mailbox partition) 2. During execution of SVC handler generate Interrupt that asserts signal of that partition (e.g. mailbox partition signal ) (adding long delay in SVC handler or adding breakpoint in SVC handler helps to easier reproduce this ) 3. Following sequence happens: * Mailbox IRQ has lower priority than SVC thus SVC is not preempted. * SVC sees that mailbox partition is blocked (as it is waiting for signal and no signals are pending) * SVC triggers pendSV i. Mailbox IRQ and pendSV are both pending * Mailbox IRQ has higher priority than pendSV thus Mailbox IRQ is executed * Mailbox IRQ calls spm_handle_interrupt i. Signal is asserted thus spm_handle_interrupt in thrd_next calls query_state_cb which returns THRD_STATE_RET_VAL_AVAIL and thus tfm_arch_set_context_ret_code is called ii. tfm_arch_set_context_ret_code sets return code using OLD value of partition PSP (as it was never updated, as it is updated in PendSV) * Mailbox IRQ return, pendsv is started and it runs mailbox partition i. Mailbox partition has 0 as signal because return value was written to wrong location is stack Patch I have attached to the mail solves this problem for us BUT it seems more like a workaround than a proper fix( Anyways it would be nice to have this problem review by SPM experts and have proper fix (maybe we have other places with same problem...)

Merging build split feature branch back to main branch

by David Hu

Hi, I’d like to give you a heads-up that build split feature branch will be merged back to main branch very soon this week. Trusted-firmware-m build split branch: https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/?h=feature… Tf-m-tests build split branch: https://git.trustedfirmware.org/TF-M/tf-m-tests.git/tree/?h=feature-build-s… Build split feature improves how NS side integrate with TF-M SPE and therefore build commands are changed for building regression tests and PSA arch tests. Could you please refer to https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/23898 for updated commands/configuration to integrate NS side and port platforms after build split? If anything is broken after build split, please let us know. It would be also appreciated if you could contribute to build split. 😊 Any feedback or comment is welcome. Best regards, Hu Ziji

How is Secure Enclave configured?

by Sunguk Bin

I have a few questions regarding RSS and Secure Enclave to see what's required and considered for SoC design to leverage RSS and why we nee to use RSS & TF-M 1. What is the difference between RSS and Secure Enclave? - Is RSS the same as Secure Enclave? - Or is it referring to any subsystem providing runtime crypto service regardless of whether it's a Secure Enclave or not? Question below is assuming RSS is a Secure Enclave...... 2. What enables TF-M to operate as a Secure Enclave? - To operate as a Secure Enclave, HW support is mandatory? a) If so, we must use a Secure Enclave IP such as cryptoisland(CI-300P-C)? b) Or can we construct a Secure Enclave with some other IPs(LCM, KMU, CryptoCell) metioned RSS doc? (by using TF-M without secure enclave IP) It feels vague whether this can be called a Secure Enclave... https://tf-m-user-guide.trustedfirmware.org/platform/arm/rss/rss_key_manage… - If HW support is not mandatory, I wonder how TF-M can operate as a Secure Enclave. - The article below seems to say that TF-M can provide Secure Enclave functionality without HW support. or I may misunderstand. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/tfm/technical_re…

Non-secure client id management

by Chris.Brand＠infineon.com

Hi, Reading through https://tf-m-user-guide.trustedfirmware.org/integration_guide/non-secure_cl… I'm wondering why so much of the work is done in the secure world. Ultimately, the secure world relies on the non-secure world to tell it the client_id, directly or indirectly. Is there a good reason for the NCSE part to reside in the secure world, rather than the non-secure? Particularly as the document states that the non-secure RTOS may have a built-in "Secure Context Manager", there may well be redundancy between that and NCSE that could be eliminated if the NCSE was in the NSPE. And the less code there is in the secure world, the less scope for vulnerabilities. If client_ids themselves were passed from the NS to the S world, it would probably be very easy to use that same interface on the NS core in a dual core system, too. Chris

Bool cast is wrong in Corestone cmake file

by Bohdan.Hunko＠infineon.com

Hi, Seems like following code $<$<BOOL:TFM_PARTITION_PLATFORM>:${CMAKE_CURRENT_SOURCE_DIR}/services/src/tfm_platform_system.c> In platform/ext/target/arm/corstone1000/CMakeLists.txt is wrong because it uses TFM_PARTITION_PLATFORM but should use ${ TFM_PARTITION_PLATFORM } If so then maybe platform maintainers can fix this.

Recommended GNU compiler version

by Quach, Brian

Is 11.2-2022.02 the recommended compiler version? I saw TF-M v1.8 states: " GNU Arm compiler version *10-2020-q4-major* has an issue in CMSE support. The bug is reported in `here <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99157>`__. Select other GNU Arm compiler versions instead. GNU Arm compiler version greater and equal than *11.3.Rel1* has a linker issue in syscall. Select other GNU Arm compiler versions instead.

Build error with customized mbedcrypto configuration

by S Krishnan, Archanaa

Hello, I am trying to build TF-M v1.8 with a custom tfm_mbedcrypto_config_profile_medium.h . I mainly do not want to use a platform specific calloc /free calls, instead use standard free() and calloc(). If I disable MBEDTLS_PLATFORM_MEMORY and MBEDTLS_PLATFORM_C in tfm_mbedcrypto_config_profile_medium.h and attempt to build TF-M, I get the following error: /arm-none-eabi/lib/thumb/v8-m.main+fp/hard/libnosys.a(sbrk.o): in function `_sbrk': /data/jenkins/workspace/GNU-toolchain/arm-11/src/newlib-cygwin/libgloss/libnosys/sbrk.c:21: undefined reference to `end' I'm able to build mbedtls package with both MBEDTLS_PLATFORM_MEMORY and MBEDTLS_PLATFORM_C disabled without any errors, the undefined reference error is only seen when building TF-M. Any thoughts on how to resolve this? Regards, Archanaa

Dependency on generated files is broken

by Bohdan.Hunko＠infineon.com

Hi all, Seems like dependency on generated files is broken. Steps to reproduce: 1. Build any platform at any mode 2. Change any .template file 3. Expected result: 1. New file is generated from the updated .template file Actual result: 1. Generated files step is skipped. My best guess will be that 1ce59292a47b1316e5d8b4d28bcaf9d8e2bdc0a5 broke it. Could this be fixed? Regards, Bohdan Hunko Cypress Semiconductor Ukraine Engineer CSUKR CSS ICW SW FW Mobile: +38099 50 19 714 Bohdan.Hunko(a)infineon.com<mailto:Bohdan.Hunko@infineon.com>

Rename TF-M branches master -> main

by Anton Komlev

Hello, Some time ago we planned to rename our master branch to main in all 6 repositories. There are multiple ways of doing that and I want to discuss with the community the best way suitable for all. I can see the following options: 1. rename master->main and use the main from one day. 2. Create the main for contribution with main->master sync. Make master R/O and delete it in 3 months. 3. Keep contributing to the master but syncing master->main. 4. Other way? I suggest option 2 but looking for better alternatives if any. Thanks, Anton

Mailbox agent API doc update - should be the final round

by Ken Liu

Hi everyone, The mailbox ns agent update document has the latest update to solidarize the API, here is the link for your review: Docs: Mailbox non-secure vectors processing (Ie4ec599c) * Gerrit Code Review (trustedfirmware.org)<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/22282> The agent-specific API should be good enough for now to handle different mailbox implementation cases, such as memory-based or non-memory-based. * Non-secure provided vectors can be referenced directly to avoid extra copy. * For non-memory-based schemes, the vectors have to be collected locally in NS Agent. We are also updating the code to validate the new API, may touch those platforms that are mailbox-related, please take care of the patches as well. SPM: Update the agent API to follow the design (I38e67578) * Gerrit Code Review (trustedfirmware.org)<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/22608/2> BR /Ken

CRYPTO_BUILTIN_KEYS

by Quach, Brian

Hi, I see "CRYPTO_TFM_BUILTIN_KEYS_DRIVER" mentioned in the documentation but where is "CRYPTO_BUILTIN_KEYS" defined? And should those target props be formatted as "${prop}"? target_compile_definitions(tfm_psa_rot_partition_crypto PUBLIC MBEDTLS_PSA_CRYPTO_DRIVERS MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS $<$<BOOL:CRYPTO_BUILTIN_KEYS>:PSA_CRYPTO_DRIVER_TFM_BUILTIN_KEY> PRIVATE $<$<STREQUAL:${CRYPTO_HW_ACCELERATOR_TYPE},cc312>:CRYPTO_HW_ACCELERATOR_CC312> MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER ) https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/secure_fw/… Regards, Brian Quach SimpleLink MCU Texas Instruments Inc.

PSA Crypto headers for v8-M TrustZone Solution - feedback gathering

by Antonio De Angelis

Hi all, following up on the presentation I gave on last tech forum (https://www.trustedfirmware.org/docs/PSACryptoHeader_June23_Antonio_shareab…) and related discussion (https://linaro-org.zoom.us/rec/share/1bBb9d06OWPACMtT_wC6C336k2Y0oeAtbM5REG… , passcode: *%RuR8Q8), I'd like to start this thread to collect feedback on TF-M's current solution as a candidate for this effort. TF-M's headers: psa « include « interface - trusted-firmware-m.git - Trusted Firmware for M profile Arm CPUs<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/interface/…> I plan to discuss the feedback received in one of the coming tech-forums (but likely not next week's). Thanks, Antonio

S/MIME email certificate usage in Mbed TLS library

by nagarajan.rak＠gmail.com

Our requirement is to send email securely from our embedded device running on STM32H7 processor. There's an SMTP client application (implemented using Mbed TLS library) running on this device, which will send emails to the recipient via custom/public email server such as smtp.gmail.com. We are planning to use S/MIME email certificate from the one of the Trusted CA, for encryption of the email message and authentication of the client/server. We learnt that each S/MIME email certificate support only one email address, but we will be having multiple devices running on the field and each device will have unique email address from which email will be sent. Getting S/MIME email certificate for device will not be feasible, is there any better way we can handle this scenario effectively. Your response to this problem is greatly appreciated. Thank you, Nagaraj

Hybrid platforms discussion follow up.

by Anton Komlev

Hi, On the last tech forum (June 22) we started discussion on multicore hybrid platforms. By this mail I’d like to follow up and continue offline analyses on new use-cases and requirements for TF-M design update. The recorded session is available here: https://linaro-org.zoom.us/rec/share/yseF-mYwUTtHHPkQJQO6IEv72xCd0Lz1pQQecc…, Passcode: 5s=Npv=w and slides: https://www.trustedfirmware.org/docs/tech_forum_20230622_Hybrid_platforms.p… The current plan is to take time, think on the use-cases and map them on requirements. With more thought and materials, we will have another session about September time to define our needs in the support of new type of platform. Please share your thoughts in reply. Thanks, Anton
