Proposal: Introduction of a standardized SMC Argument Validation Framework

by Sandrine Bailleux

Hi all, I am sending the email below on behalf on Kenneth Kabogo, who unfortunately is facing issues with the mailing list. Regards, Sandrine Afsa ---- Dear TF-A Maintainers, I am proposing the introduction of a standardized SMC Argument Validation Framework into the TF-A codebase. Over the past several weeks of security auditing across multiple platform ports, I have identified a recurring architectural failure mode termed "Privilege-Blind Forwarding" (PBF). This occurs when an EL3 handler receives a non-secure physical address and forwards it to a secure memory operation without re-validating the range against the platform's current security state (GPT/RMM). Furthermore, there is a widespread Structural TOCTOU (Double-Fetch) vulnerability in many SiP ports where handlers validate arguments but later re-fetch them from non-secure memory, allowing a malicious caller to swap addresses mid-execution. The proposed framework addresses these via an Atomic Shadow-Copy design pattern, requiring all SMC arguments to be unmarshaled into EL3 registers/memory once before validation. The 3-part prototype and migration guide are available for review on Gerrit: Framework Hardening (Core Logic): https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/47441 Architectural Guidance (Documentation): https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/47465 Arm Platform Demonstration (Migration Guide): https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/47466 I look forward to the community's feedback on this architectural shift. Best regards, Kenneth Kabogo

ZynqMP regression with NUMA_AWARE_PER_CPU changes with ENABLED_LTO : Linux runtime hang due to EL3 re-entry

by Kummari, Prasad

[AMD Official Use Only - AMD Internal Distribution Only] Hello Maintainers, We are observing a reproducible runtime regression on the ZynqMP (Cortex-A53) platform after enabling LTO (ENABLED_LTO=1) and merging the changes from the topic NUMA_AWARE_PER_CPU into our integration branch (https://github.com/ARM-software/arm-trusted-firmware/commit/7303319b3823e9e…). Summary of the issue 1. Baseline behavior * Platform: ZynqMP (Cortex-A53) * Configuration: ENABLED_LTO=1 * Without NUMA_AWARE_PER_CPU: Linux boots and runs stably * After merging NUMA_AWARE_PER_CPU, Linux boots but hangs during runtime * During the hang, CPUs are observed to unexpectedly re-enter EL3 * Re-entry into EL3 should not occur during normal Linux runtime execution and strongly suggests corruption or mismanagement of PSCI and/or per-CPU state(arm-trusted-firmware/lib/per_cpu/aarch64/per_cpu_asm.S at master * ARM-software/arm-trusted-firmware<https://github.com/ARM-software/arm-trusted-firmware/blob/master/lib/per_cp…>) * Reverting the NUMA_AWARE_PER_CPU changes restores stable Linux execution * The issue is reproducible only when NUMA_AWARE_PER_CPU is present * This clearly identifies NUMA_AWARE_PER_CPU as the regression source 2. Suspect with LTO * With NUMA_AWARE_PER_CPU enabled, LTO breaks the per-CPU base calculation * BL31 contains hand-written assembly that relies on linker-script symbols (e.g., per-CPU section boundaries) * Under LTO, symbol placement and retention are no longer guaranteed in the same way, leading to incorrect per-CPU base computation * This results in corrupted per-CPU data and subsequent erroneous PSCI suspend behavior (EL3 re-entry) 3. CPU idle dependency * The following kernel configuration options are enabled: * CONFIG_CPU_IDLE=y * CONFIG_CPU_IDLE_MULTIPLE_DRIVERS=y * CONFIG_CPU_IDLE_GOV_MENU=y * CONFIG_DT_IDLE_STATES=y * This further suggests the issue is triggered during CPU idle / suspend-resume paths, where correct per-CPU state handling is critical Based on the above: * This is specific to NUMA_AWARE_PER_CPU combined with LTO * The failure mode points to per-CPU base calculation and PSCI state corruption * Reverting NUMA_AWARE_PER_CPU fully restores stability on ZynqMP We wanted to report this issue upstream and seek guidance on: * Whether NUMA_AWARE_PER_CPU is expected to be LTO-safe on platforms relying on linker-defined per-CPU sections * Or if additional constraints / fixes are required for platforms like ZynqMP We are happy to provide further logs, configuration details, or help to fixes. Regards, Prasad Kummari

Re: Questions about Chain-of-Trust and RSE Connectivity

I reproduced your initial email sent Dec 18th 2025 below and Cced relevant folks just in case. Regards, Olivier. ____________________________________________________________ Hello, I'm firmware developer for RD-V3-R1 chipset. I have developed our firmware based on Neoverse Reference Platform RD-INFRA-2025.07.03, but I have also kept an eye on the code to ensure we remain in step with the latest release. While inquiring on the TF-M forum to update the TF-M code, I also developed a query regarding the TF-A section. Re: Several Questions related to RSE Provisioning - TF-M - lists.trustedfirmware.org<https://lists.trustedfirmware.org/archives/list/tf-m@lists.trustedfirmware.…> This link includes that RSE API codes are removed in the SotA TF-A codes. I check this in the TF-A commit. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/46314 I was already aware that this API was not used outside of test code. However, I would like to know the reason why that code was removed, beyond the simple fact that it was not being used. Is it possible that Chain-of-Trust is established in whole firmware stack from RSE ROM to AP BL33 bootloader, without RSE assist? If possible, what does TF-A rely upon as the basis for trust in establishing the Root of Trust? Our team believed that CoT was established on the premise of the RSE API, and was therefore designing to ensure the trustworthiness of the entire firmware using that code. However, we recognise that to use the latest version of the code, we must abandon that belief and design in a different manner. Before the new version of RD-INFRA is released, we intend to resolve this internally as a team.

[RFE] lib/el3_runtime: set NS bit if secure el2 is not implemented

by Pawandeep Oza (QUIC)

Please have a look at following patch, where on our platform we try to maintain single image of TFA (for custom CPU and Cortex A55) Cortex A55 does not have Secure EL2 implemented, while on the other hand our custom CPU has secure EL2 (and we run Hafnium there) On Cortex A55 ARM AEM model: write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); the context was set before as u_register_t icc_sre_el2_val = ICC_SRE_DIB_BIT | ICC_SRE_DFB_BIT | ICC_SRE_EN_BIT | ICC_SRE_SRE_BIT; and setting ICC_SRE_DIB_BIT | ICC_SRE_DFB_BIT causes crash since secure EL2 is not implemented. resulting into following patch which resolves the issue. seeking feedback/discussion if I can post it to upstream TFA, let me know if I am missing something here. lib/el3_runtime: set NS bit if secure el2 is not implemented before setting icc_sre_el2 set NS bit for non-secure context so that the ICC_SRE_DIB_BIT and ICC_SRE_DFB_BIT are preserved Signed-off-by: Oza Pawandeep <quic_poza(a)quicinc.com> diff --git a/lib/el3_runtime/aarch64/context_mgmt.c b/lib/el3_runtime/aarch64/context_mgmt.c index e31255868..5100f2f00 100644 --- a/lib/el3_runtime/aarch64/context_mgmt.c +++ b/lib/el3_runtime/aarch64/context_mgmt.c @@ -1411,7 +1411,18 @@ static void el2_sysregs_context_restore_gic(el2_sysregs_t *ctx, uint32_t securit u_register_t scr_el3 = read_scr_el3(); #if defined(SPD_spmd) && SPMD_SPM_AT_SEL2 - write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + if (is_feat_sel2_supported()) { + write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + } else { + write_scr_el3(scr_el3 | SCR_NS_BIT); + isb(); + + write_icc_sre_el2(read_el2_ctx_common(ctx, icc_sre_el2)); + + write_scr_el3(scr_el3); + isb(); + } + #else write_scr_el3(scr_el3 | SCR_NS_BIT); isb(); Regards, Oza.

TF-A Tech Forum Dec 11th 4.00pm (UK) - TF-RMM Live Firmware Activation (design update)

by Olivier Deprez

Hi, On Dec 11th in the TF-A Tech Forum at 4.00pm UK, Soby Mathew will present a design update on TF-RMM Live Firmware Activation: This presentation describes the revised TF-RMM Low-VA MMU and global-runtime-data design required to support Live Firmware Activation (LFA). Compared to the earlier approach (outlined in the TFA Tech Forum session on 12-Jun-2025 [1] ), which assumed mostly fixed boot time mappings and per-platform handcrafted Low-VA contexts, the new design is driven by several changes in RMM specification: RMM must now support runtime mapping/unmapping of PAs for RMM objects like struct granule , reuse those dynamic mappings across LFA transitions. These PAs can come either from NS world at runtime or EL3 reservation from RMM carveout. In order to migrate Stage 1 dynamic mappings across LFA instances, RMM needs to reduce dependence on platform-specific MMU setup, and provide a structured framework for allocating, versioning and migrating global runtime data. The Stage 1 Low-VA is therefore split into static and dynamic regions managed by the common xlat layer. The detailed design is captured in the TF-RMM wiki RFC “TF-RMM Live Firmware Activation [2]” and builds on the initial design presented in the TFA Tech Forum session on 12-Jun-2025 [1] : [1] Previous LFA discussion: https://github.com/TF-RMM/tf-rmm/wiki/TFA-Tech-Forum-Presentations [2] https://github.com/TF-RMM/tf-rmm/wiki/RFC:-TF%E2%80%90RMM-Live-Firmware-Act… Regards, Olivier.
