Hello, I would like to use PSA calls for an application on STM32MP2 platform. I've seen the psa_call() API that I could use, in drivers/arm/rse/rse_comms.c. The problem is that it is based on MHU mailbox, which I don't have on STM32MP2. So I was planning plan to disentangle RSE comms and MHU, having a new file in the same directory to manage MHU. This code should then be under a flag, I could re-use PLAT_MHU_VERSION. Setting it to 0, would mean no MHU. AFAICT TF-M uses that split with a dedicated file: rse_comms_hal.c: Abstracts MHU message sending and receiving. (see https://tf-m-user-guide.trustedfirmware.org/platform/arm/rse/rse_comms.html). Do you think this approach sounds right? Thanks, Yann

How to map a physical address using `mmap_add_dynamic_region_alloc_va`?

by 钱非凡

Hi experts, I tried to allocate a physical memory address in Linux Kernel, and pass the memory address to tf-a using smc call. As I asked in previous mails (https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.…), tf-a can not access the physical memory address directly, so I try to use the `mmap_add_dynamic_region_alloc_va` function in `xlat_table_v2` Library, and map the physical memory in tf-a. After calling the function, It does return a new virtual memory address, but I still failed to access the address, is there any details I have missed? Here is the code: ``` NOTICE("phys_addr: 0x%lx, virt_addr: 0x%lx\n", phys_addr, virt_addr); int rc = mmap_add_dynamic_region_alloc_va(phys_addr, ptr_virt_addr, size, MT_NS | MT_RW_DATA); if (rc) { WARN("Failed to map memory at 0x%lx: %d\n", phys_addr, rc); return; } NOTICE("virt_addr_el3: 0x%lx\n", virt_addr_el3); NOTICE("virt_addr_el3[0] = 0x%x\n", *((uint32_t *)virt_addr_el3)); ``` Here is the output: ``` NOTICE: phys_addr: 0x40f0000, virt_addr: 0xffff0000040f0000 NOTICE: mm.base_va: 0 NOTICE: mm.base_va: 100000000 NOTICE: virt_addr_el3: 0x100000000 [ 38.540464] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: [ 38.546584] rcu: 4-...0: (1 ticks this GP) idle=4224/1/0x4000000000000000 softirq=125/125 fqs=2625 [ 38.555651] (detected by 0, t=5252 jiffies, g=-779, q=16 ncpus=8) [ 38.561843] Task dump for CPU 4: [ 38.565075] task:main state:R running task stack:0 pid:195 ppid:181 flags:0x00000002 [ 38.575015] Call trace: [ 38.577464] __switch_to+0xe4/0x160 [ 38.580975] 0x42 ``` I would be grateful for any advice or suggestions you may have.

Arm TF-A can not access linux kernel's virtual/physical address?

by 钱非凡

In my opinion, Arm TF-A (EL3) has higher privileges than Linux Kernel (EL1), and Secure World should be able to access all memory address in Normal World. To verify this feature, I added a new SMC call in Arm TF-A and wrote a kernel module to test it (on a Hikey960 Development Board). But the program does not run as expected that Arm TF-A stucked while accessing the memory address passed by Linux Kernel. Here is my kernel module, which uses `alloc_pages` to acquire a physical address, and uses `page_address` converting it to a virtual address. And the module passes the physical address and the virtual address to Arm TF-A using `smc #0`: ```cpp static int __init smc_testing_init(void) { uintptr_t phys_addr, virt_addr; pr_info("Mmodule loaded\n"); phys_addr = (uintptr_t) alloc_pages(GFP_KERNEL, 2); virt_addr = (uintptr_t) page_address((struct page *) phys_addr); memset((void *) virt_addr, 'A', PAGE_SIZE << 2); printk("phys_addr: 0x%llx, virt_addr: 0x%llx\n", (uint64_t) phys_addr, (uint64_t) virt_addr); asm volatile( "ldr x0, =0xC8000003\n" "mov x1, %0\n" "mov x2, %1\n" "smc #0\n" : : "r" (phys_addr), "r" (virt_addr) : "x0", "x1", "x2" ); __free_pages((struct page *) phys_addr, 2); return 0; } static void __exit smc_testing_exit(void) { pr_info("Module unloaded\n"); } ``` And here is the handler's code in Arm TF-A, which prints the addresses of physical address and virtual address, and access the first element of the memory address: ```cpp if (0xC8000003 == smc_fid) { uintptr_t virt_addr = x3; NOTICE("phys_addr: 0x%lx, virt_addr: 0x%lx\n", phys_addr, virt_addr); NOTICE("virt_addr[0] = 0x%x\n", *((uint32_t *)virt_addr)); NOTICE("phys_addr[0] = 0x%x\n", *((uint32_t *)phys_addr)); SMC_RET0(handle); } ``` Here is the output, Arm TF-A handles the request successfully, but failed to access the memory address passed by Linux Kernel: ```bash # insmod ./smc_testing.ko [ 75.259590] smc_testing: loading out-of-tree module taints kernel.

Re: Integrate TF-A and PSA Crypto API with PUFcc

by Jothikumar Mani

HI Andy, Thank you for explaining, psa-arch-test(psa certified api compliance) testsuite currently used with TFM +MbedTLS environment as a release gate, and there is trusted service team whom were running the psa-arch-test package on arm-A class devices. Coming back to the question related to psa-arch-test, the current available package should suffice to check the compliance of crypto necessary tasks/functinoality, fyi we have already validated the latest psa-arch-test repo with the mbedtls 3.6. So I would not be more concern about the psa-arch-test being compliant to latest 1.2.1 spec. because between 1.1.0 and 1.2.1 there were minimal changes which is not showstopper for the psa certified api certification. Regards, JK From: Andy Chen <andychen(a)pufsecurity.com> Date: Thursday, 25 July 2024 at 5:30 AM To: Jothikumar Mani <Jothikumar.Mani(a)arm.com>, Manish Badarkhe <Manish.Badarkhe(a)arm.com>, tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Cc: Diya Soubra <Diya.Soubra(a)arm.com>, Victoria Lee <victorialee(a)pufsecurity.com>, Andrew <andrewirvin(a)pufsecurity.com> Subject: 回覆: Integrate TF-A and PSA Crypto API with PUFcc Hi Jothikumar and Manish, It's great to discuss with you and thanks. Sure, it's more clarity with usage scenarios: 1. As a Security IP provider, our PUFcc functions as a Hardware Root of Trust. However, mbedTLS currently doesn't fully support HRoT. Therefore, we are integrating directly into the PSA Crypto API, which permits customization. 1. While working on PSA L3 or L2R, we frequently face version conflicts. That why, in this project, we aim to confirm these version issues (including the dev. and test bench). 1. This also means that both TF-A and TF-M support PSA Crypto API, so we can also support both through this package. There is our PSA Software Package with PUFcc. We try to find the best way to support cryptographic tasks. Additionally, we plan to use the same development platform as ARM to ensure optimal compatibility for our customers. It means we would try to know the FPV, although I'm not sure if we can add external IPs. If I misunderstood or you have any ideas, please feel free to tell me.

We try to integrate the PSA Crypto API with PUFcc (Our Crypto Engine) on TF-A. However, there are multiple versions included, and we need your assistance for specification clarification. Please ensure the versions match your recommendations. For TF-A, we plan to integrate with: TF-A lts-v2.10.5 PSA Crypto API - v1.1.0 PSA Certified APIs Architecture Test Suite - v1.6 [MB]: This looks fine. As TF-A lts-v2.10.5 using mbedTLS v3.6.0 which is compliance with PSA Crypto API - v1.1.0 but mbedTLS team can provide more detailed answer on this and also on test suite PSA Certified APIs Architecture Test Suite - v1.6. TF-A It would be beneficial to use the same hardware (FPGA) and tools as the ARM development team. If we can confirm which models are used for TF-A , scripts or details with the ARM hardware That would be grateful. [MB]: We are using FVP AEM model i.e. FVP_Base_RevC-2xAEMvA (Model version: 11.26, Build: 11). Test Run with PSA Crypto you can find here: https://ci.trustedfirmware.org/job/tf-a-builder/4029201/ (today's daily run) PSA Crypto API - The test bench is using the PSA Crypto API v1.1.0, and it is published in 2022. And Now is v1.2.1 in March 2024. I not sure it is a good choose or not. [cid:image001.png@01DADE0E.1BA75330] [MB]: It looks like arch-test is not upgraded to use v1.2.1 PSA Crypto API. Added Jothikumar Mani, he may have idea about this. Test Bench - For the "PSA Certified APIs Architecture Test Suite - v1.6," we would like to identify which test codes (test_c001 to test_c067) are relevant for TF-A. [MB]: Again, TF-A is not using this test suite, so we don't have any insights unless we review all these tests. TF-A mainly uses the following PSA_* APIs for signature verification, hash calculation, and hash comparison. psa_crypto_init mbedtls_md_psa_alg_from_type psa_set_key_algorithm psa_set_key_type psa_set_key_usage_flags psa_import_key psa_destroy_key psa_verify_message psa_hash_compute psa_hash_compare Thank you very much!!!

We try to integrate the PSA Crypto API with PUFcc (Our Crypto Engine) on TF-A. However, there are multiple versions included, and we need your assistance for specification clarification. Please ensure the versions match your recommendations. For TF-A, we plan to integrate with: TF-A lts-v2.10.5 PSA Crypto API - v1.1.0 PSA Certified APIs Architecture Test Suite - v1.6 [MB]: This looks fine. As TF-A lts-v2.10.5 using mbedTLS v3.6.0 which is compliance with PSA Crypto API - v1.1.0 but mbedTLS team can provide more detailed answer on this and also on test suite PSA Certified APIs Architecture Test Suite - v1.6. TF-A It would be beneficial to use the same hardware (FPGA) and tools as the ARM development team. If we can confirm which models are used for TF-A , scripts or details with the ARM hardware That would be grateful. [MB]: We are using FVP AEM model i.e. FVP_Base_RevC-2xAEMvA (Model version: 11.26, Build: 11). Test Run with PSA Crypto you can find here: https://ci.trustedfirmware.org/job/tf-a-builder/4029201/ (today's daily run) PSA Crypto API - The test bench is using the PSA Crypto API v1.1.0, and it is published in 2022. And Now is v1.2.1 in March 2024. I not sure it is a good choose or not. [cid:image001.png@01DADE0E.1BA75330] [MB]: It looks like arch-test is not upgraded to use v1.2.1 PSA Crypto API. Added Jothikumar Mani, he may have idea about this. Test Bench - For the "PSA Certified APIs Architecture Test Suite - v1.6," we would like to identify which test codes (test_c001 to test_c067) are relevant for TF-A. [MB]: Again, TF-A is not using this test suite, so we don't have any insights unless we review all these tests. TF-A mainly uses the following PSA_* APIs for signature verification, hash calculation, and hash comparison. psa_crypto_init mbedtls_md_psa_alg_from_type psa_set_key_algorithm psa_set_key_type psa_set_key_usage_flags psa_import_key psa_destroy_key psa_verify_message psa_hash_compute psa_hash_compare Thank you very much!!!

TF-A Tech Forum - Jul 25th 2024 - Unification of Chain of Trust Descriptors

by Olivier Deprez

Hi, On Jul 25th in the TF-A Tech Forum: Unification of Chain of Trust Descriptors - presented by Xialin Liu Currently, the Chain of Trust is implemented using C data structures built into the firmware or through device tree nodes. Maintaining both formats can lead to maintenance challenges. Therefore, we are standardizing the provision of Chain of Trust descriptors exclusively via the device tree and providing a tool to convert device tree descriptors into C source files. This approach simplifies the process, ensuring consistency and reducing the potential for errors associated with managing multiple formats. Regards, Olivier. TF-A Tech Forum Thursday Jul 25, 2024 ⋅ 5pm – 6pm Central European Time - Paris We run an open technical forum call for anyone to participate and it is not restricted to Trusted Firmware project members. It will operate under the guidance of the TF TSC. Feel free to forward this invite to colleagues. Invites are via the TF-A mailing list and also published on the Trusted Firmware website.

Firmware Partition Filesystem query

by Ghennadi Procopciuc

Greetings everyone, I came across the following paragraph while reading the 'Firmware Partition Filesystem' chapter from EBBR v2.2.0 and I would like to clarify my understanding: Where possible, firmware images and data should be stored in a filesystem. Firmware can be stored either in a dedicated firmware partition, or in certain circumstances in the UEFI System Partition (ESP). Using a filesystem makes it simpler to manage multiple firmware files and makes it possible for a single disk image to contain firmware for multiple platforms. Dedicated firmware partitions should be formatted with a FAT filesystem as defined in UEFI § 13.3 File System Format. Dedicated firmware partitions should use the same /FIRMWARE directory hierarchy. OS tools shall ignore dedicated firmware partitions, and shall not attempt to use a dedicated firmware partition as an ESP Questions: 1. Does the above paragraph mean that, if the device allows, all firmware binaries (TF-A, U-Boot, and some others) must be stored in a dedicated firmware partition formatted with a FAT filesystem and GUID Partition Table (GPT) disk layout? 2. If so, would this also mean that, where possible, the BootROM or a (first stage) bootloader running before TF-A should have GPT and FAT support embedded support to load one of the TF-A stages (BL1/BL2)? Regards, Ghennadi

Proper message for ERRATA_NOT_APPLIES case

by Bollapalli, Maheedhar Sai

Hi, On AMD-Xilinx ZynqMP platform for ERRATA_NOT_APPLIES case; the log appearing on the console is as below: "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472was not applied". We checked ZynqMP code and found that the ZynqMP cpu revision was higher than the cpu revision intended in the erratum and hence it was not applicable and not applied. The message seems inappropriate to us as from log message it is not clear why it wasn't applied. Our suggestion is that in the log message instead of "not applied" it should be mentioned as "not applicable" as indicated below to reflect the reason properly. "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472 was not applicable". Regards, Maheedhar.
