Deprecation OpenSSL 1.x support after TF-A v2.15

by Matthew Ellis

Hi all, This email is to inform the community that support for OpenSSL 1.x is planned to be deprecated going forward. TF-A v2.15 will be the last release for which OpenSSL 1.x receives full support. The primary reason for this change is that OpenSSL 1.1.1 reached end-of-life in September 2023, and OpenSSL 1.0.2 reached end-of-life significantly earlier. The OpenSSL project now recommends migration to OpenSSL 3.x for ongoing security updates, maintenance and feature development. While OpenSSL offers commercial extended support for some legacy releases, the resulting patch sets are not generally available to the wider open-source community. As a result, TF-A maintainers and contributors cannot reasonably test, validate or debug against these versions. Supporting software versions that are not publicly available creates practical challenges for CI coverage, issue reproduction and long-term maintenance. For these reasons, OpenSSL 3.x will become the supported OpenSSL version for TF-A. To be clear, this change does not mean that TF-A will intentionally remove OpenSSL 1.x compatibility or deliberately break existing users. Existing compatibility code will remain in place where practical. However, after TF-A v2.15: * OpenSSL 1.x will no longer be a supported configuration. * CI testing will not cover OpenSSL 1.x. * Bug reports affecting only OpenSSL 1.x may not be investigated. * New features and maintenance changes will not be required to preserve OpenSSL 1.x compatibility. * Patches to retain compatibility may be accepted on a best-effort basis, but no guarantees will be provided. Users are therefore strongly encouraged to migrate their build environments to OpenSSL 3.x. OpenSSL 3.x is the actively maintained upstream release series and provides ongoing security support, public availability of fixes, improved maintainability, and alignment with the direction of the OpenSSL project. Adopting OpenSSL 3.x also ensures that TF-A can be developed and tested against versions that are available to all maintainers and contributors. Comments are welcome. Regards, Matthew

Proposal to unify tf.org vulnerability referencing in NVD

by Sandrine Bailleux

Hi everyone, I am sending this email to all tf.org project mailing lists to ensure all maintainers are aware and on board regarding this matter. If you have any concerns or questions, please reply on tf.org Discord #general channel, where I'll create a thread, as I think it will be much easier than dealing with cross-mailing lists emails. Background When a security vulnerability is discovered in one of the trustedfirmware.org projects, it is common to request a "Common Vulnerabilities and Exposures" (CVE) number. This number uniquely references the issue, which can then be searched in the vulnerability databases. One of these databases is NIST's "National Vulnerability Database" (NVD): https://nvd.nist.gov<https://nvd.nist.gov/vuln/detail/CVE-2023-51712> Entering a specific CVE number in NVD search engine will allow you to easily find the details of a specific issue, for example: https://nvd.nist.gov/vuln/detail/CVE-2023-51712 However, sometimes one is not looking for a specific CVE number but rather wants to list all known vulnerabilities affecting a particular project. For this, one can use the Common Platform Enumerations (CPE) search engine: https://nvd.nist.gov/products/cpe/search CPE is a structured naming scheme that includes information like the vendor name, the project name, the version / tag, and so on. See https://nvd.nist.gov/products/cpe for more details. So for example, https://nvd.nist.gov/vuln/detail/CVE-2023-51712 referenced above has the following CPE: cpe:2.3:o:arm:trusted_firmware-m:*:*:*:*:*:*:*:* This basically means * CPE version 2.3 is in use * 'o is the type of project, in this case it stands for Operating Systems (which is probably the closest match for low-level code like TF-M) * 'arm' is the vendor (that is wrong, see below) * 'trusted_firmware-m' is the project name, Problem statement It appears that CPEs used in NVD to reference vulnerabilities in tf.org projects differ a lot across projects. For some projects, there's even multiple of them. Sometimes the vendor is "arm", sometimes it's "linaro", or something else. Some of the TF-A and MbedTLS maintainers have initiated discussions with NVD to get this simplified and unified, but it would make sense to align other tf.org projects as well. Proposal CPE naming rules are that the vendor name should the parent organization of the project. Thus the proposal would be for all tf.org projects to use "trustedfirmware" as the vendor name in their CPE. For example: cpe:2.3:o:trustedfirmware:trusted_firmware-m:*:*:*:*:*:*:*:* cpe:2.3:a:trustedfirmware:mbed_tls:*:*:*:*:*:*:*:* We're only proposing to change the vendor name here ; each project is then free to choose how they want the project name or the type of software project they want to encode there. Thanks for reading, Best regards, Sandrine Afsa

Re: Guidance on direct Linux boot from TF-A (bypassing U-Boot) on ARM64

by Olivier Deprez

Hi, I would suggest looking into the platform ports: https://trustedfirmware-a.readthedocs.io/en/latest/plat/arm/fvp/fvp-specifi… https://trustedfirmware-a.readthedocs.io/en/latest/plat/rpi3.html#build-ins… RPI3_DIRECT_LINUX_BOOT https://trustedfirmware-a.readthedocs.io/en/latest/plat/qemu.html#qemu-virt… ARM_LINUX_KERNEL_AS_BL33 Regards, Olivier. ________________________________ From: Joita Mitra <joita.m(a)delopt.co.in> Sent: 11 June 2026 09:19 To: tf-a-owner(a)lists.trustedfirmware.org <tf-a-owner(a)lists.trustedfirmware.org> Subject: Guidance on direct Linux boot from TF-A (bypassing U-Boot) on ARM64 Hi, I am working on an RZ/G2L based platform and exploring the possibility of booting Linux directly from TF-A without using U-Boot as BL33. Current boot flow: BL2 -> BL31 -> U-Boot (BL33) -> Linux Target boot flow: BL2 -> BL31 -> Linux I have been studying the TF-A image loading framework, including: * desc_image_load.h * bl2_image_load_v2.c * bl2_plat_mem_params_desc.c * bl31_main.c * bl31_prepare_next_image_entry() My understanding is that BL2 loads images according to the image descriptors and passes entry point information to BL31 through the BL33 descriptor. I modified the BL33 descriptor to point to the Linux kernel entry address instead of U-Boot and attempted to transfer execution directly to Linux from BL31. However, Linux does not start successfully, which suggests that additional preparation normally performed by U-Boot may be missing. I would appreciate guidance on the following: 1. Is using the BL33 descriptor to describe the Linux kernel the correct architectural approach when bypassing U-Boot? 2. How should the Linux kernel Image and DTB be loaded from BL2? * Should Linux be treated as BL33? * Should the DTB be loaded as a separate image descriptor? * Is there an existing TF-A mechanism intended for this use case? 3. Which TF-A components are typically modified to support direct Linux boot? * BL2 image loading descriptors? * BL31 handoff logic? * Platform-specific image loading code? 4. Are there any reference implementations or platforms in TF-A that directly boot Linux without U-Boot? 5. Are there any ARM64 Linux boot protocol requirements that TF-A must satisfy before transferring control to Linux? Any guidance or examples would be greatly appreciated. Thank you.

EL3 SPMC shmem datastore sizing for FFA_MEM_RETRIEVE_REQ snapshot

by Daniel Boulby

Hi all, I am sending this note to get feedback from platform maintainers on an EL3 SPMC change in my current series (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/50778/). The patch updates spmc_ffa_mem_retrieve_req() to take a snapshot of the caller's FFA_MEM_RETRIEVE_REQ descriptor into the EL3 SPMC shmem datastore before validation and response handling. The intent is to avoid repeatedly reading mutable fields from the caller-owned TX buffer while the request is being processed. In other words, once the request enters EL3 SPMC, we operate on a stable local copy rather than on memory that remains under the caller's control. The EL3 SPMC datastore is already used to cache shared memory transaction descriptors. With this change, it is also used to hold a temporary copy of the retrieve request. That means datastore sizing becomes more important, since a valid larger retrieve request may now fail if the backing datastore is too small. The datastore sizes are defined in platform_def.h (https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/… for the fvp platform) and while looking through the existing platform definitions, I noticed that datastore sizes vary quite a lot. For example, some platforms provide a relatively large backing store, while others define much smaller regions. In particular, rdn2 currently defines only a 1024-byte datastore. My concern is that for such platforms, larger memory-share / retrieve flows could fail simply because the datastore is too small to hold the request snapshot. Before I proceed further, I wanted to ask platform maintainers: 1. Is there any platform-specific reason for these reduced datastore sizes? 2. If not, would maintainers be happy for these datastore sizes to be increased so they can accommodate larger valid transactions? In short, I want to confirm whether the smaller datastore definitions are deliberate platform constraints, or whether they should be treated as undersized defaults that now need revisiting. Feedback from maintainers would be very helpful before I post the next revision. Kind Regards, Daniel Boulby
