Eliminate unnecessary space in tfm_s.bin

by Sherry Zhang

Hi, Currently, in the compiler link script, the CMSE VENEER section is placed at a fixed address which is at the end of tfm code. See code for armclang<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e…> and gnu arm<https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/platform/e…>. Placing the veneers at the fixed address has the benefit that the when the secure image updates, the veneer symbols remain unchanged. So, the nonsecure image does not have to be updated together. The problem is that the size of tfm_s.bin is always the same in different TF-M build configurations(debug mode, release mode, profile small, profile large and so on). So, there can be large empty space between the end of tfm code and the veneer section. As we discussed on today's tech forum meeting, I propose to move the LR_VENEER from the end of tfm code to right after the secure vector table. In this way, the space between the tfm code and the veneers section is eliminated. Also, the supported number of interrupts for each platform is fixed. So, the size of the vector table is fixed for each platform. So, the start address of veneer section is still fixed for each platform. The size of tfm_s.bin is reduced significantly after this change. Take the AN521 platform for example, the size of tfm_s.bin has a 70 percent reduction. The link script change for armclang<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/12620/6/plat…> and gnu arm<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/12620/6/plat…> in this patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/12620/> can help me demonstrating my proposal. I am not hurry asking for review and merge this patch. As it impacts all the platforms, I want to get confirmed that all platforms which are using the common link script are happy with this proposal. Any comments or especially concerns on this proposal? Thanks, Regards, Sherry Zhang

Re: [TF-M] Change in ...trusted-firmware-m[master]: Platform: Refine image flash layout

by Thomas Törnblom

I'm working on the IAR part of this and I'm having a problem with the following test in isolation level 3: --- Running Test Suite TFM IRQ Test (TFM_IRQ_TEST_1xxx)... > Executing 'TFM_NS_IRQ_TEST_SLIH_1001' Description: 'SLIH HANDLING Case 1' --- If I run the test at full speed, it will run into a MemManage fault while if I single step through the entire test it will pass. Is there a race condition somewhere in there? If I disable the SLIH tests it succeeds. The exception happens when dereferencing "dev" in this function: bool timer_cmsdk_is_initialized(const struct timer_cmsdk_dev_t* dev) { return dev->data->is_initialized; } dev is 0x30002440 at the time. I've been trying to figure out what part of the memory protection system it is that is causing the exception. DACCVIOL is set and MMFAR shows the faulting address. Ideas? The build line: cmake -GNinja -S .. -B . -DTFM_PLATFORM=arm/musca_b1/sse_200 "-DTFM_TOOLCHAIN_FILE=..\toolchain_IARARM.cmake" -DTEST_NS=ON -DTEST_S=ON -DCMAKE_BUILD_TYPE=Debug -DBL2=ON -DTFM_ISOLATION_LEVEL=3 -DTEST_NS_SLIH_IRQ=ON -DTEST_NS_QCBOR=OFF Notice that this build runs into a linker bug in the IAR toolchain and I have a non-released fixed version I'm using, in case anyone is attempting to replicate the issue.

Any existing efforts on enabling X.509 certificate support inside TF-M

by Li, Jun R

Hi everyone, I’m wondering if there is any existing effort on enabling X.509 CSR generation and certificate verification inside TF-M? Our project has some custom secure partitions which need to generate the CSR and verify the issued certificates by themselves. The current TF-M implementation hasn’t added X.509’s support. So, I’m wondering if any open source project already does that which we can leverage? Regards, Jun Li Intel Corporation, CA

Tip on cloning TF-M on OS X Monterey

by Kevin Townsend

I recently switched to a new MBP that ships with OS X Monterey, and on both 12.0 and 12.1 (released this week) git clone seems to be broken when you're using HTTP rather than SSH: digital envelope routines:CRYPTO_internal:bad key length In order to clone TF-M, I had to make the following changes. 1. Add these details to $HOME/.ssh/config (microbuilder being my github username, associated with my TF-M account): Host trustedfirmware.org User microbuilder Hostname review.trustedfirmware.org Port 29418 IdentityFile ~/.ssh/id_rsa IdentitiesOnly yes 2. Then try to clone with: $ git clone trustedfirmware.org:/TF-M/trusted-firmware-m.git This fails, however, since it tries to clone tf-m-tests.git, so: 3. Edit lib/ext/tf-m-tests/fetch_repo.cmake, changing: FetchContent_Declare(tfm_test_repo GIT_REPOSITORY trustedfirmware.org:TF-M/tf-m-tests.git # GIT_REPOSITORY https://git.trustedfirmware.org/TF-M/tf-m-tests.git GIT_TAG ${TFM_TEST_REPO_VERSION} GIT_PROGRESS TRUE ) This let me at least clone TF-M until the issues with HTTP-based cloning are fixed. Hope this is useful to someone else working on OS X natively. Kevin

IPC mode support for Audit log service

by Bøe, Sebastian

Hi, for PSA Certification level 2 a log of significant security events is required. Which I assume should be done with the Audit log service. But the Audit log service does not support IPC mode. Should PSA Certification level 2 be done with IPC mode or with library mode?
