Hello everyone, Following our recent release, I'm pleased to provide more details on recent developments in our CI for QEMU. Linaro’s continuous integration platform OpenCI supports running emulated tests on QEMU. The tests are kicked off on Jenkins and deployed through the Linaro Automation and Validation Architecture LAVA. The obvious benefit of this is it makes it relatively easy to test TF-A in CI without a complex hardware setup, much like we do with FVPs. For this reason, we have added scripts to our OpenCI scripts repository to enable running this form of automated tests on QEMU. The initial patches provide a set of end-to-end boot tests (TF-A -> Linux shell prompt) that are included in our daily job [1]. The long term plan is to use this and further QEMU tests to gate patch submission (CI +1, +2), however, this is will only happen when we have confidence in their stability. You can view a sample test run here [2]. You can also reproduce the test setup manually in OpenCI or locally. In OpenCI this is done by running the tf-a-builder job with `qemu-boot-tests` as the test group [3]. In your local setup, this is done with the following command line: ``` $ test_run=1 \ workspace=$(mktemp -d) \ nfs_volume="$workspace" tfa_downloads="https://downloads.trustedfirmware.org/tf-a" tf_root="/path/to/trusted-firmware-a/" \ tftf_root="/path/to/tf-a-tests/" \ test_groups="qemu-boot-tests/qemu-default:qemu-linux.rootfs-fip.uefi-virt" \ bash -x $ci_root/script/run_local_ci.sh ``` We highly encourage you to contribute to the QEMU CI scripts if you can! Whether that be helping extend the tests or providing enhancements. We are also looking for help maintaining this specific area and the infrastructure around it - if this of interest, please do reach out! Cheers! Harrison [1] https://ci.trustedfirmware.org/job/tf-a-main [2] https://tf.validation.linaro.org/scheduler/job/1168495 [3] https://ci.trustedfirmware.org/job/tf-a-builder/

Re: 回复： building secure boot tf-a images without ROTK controlled by SW build engineer

by Neely, Brian

Hello, Just following up on my question regarding HSMs (pasted below). Do any of the maintainers of cert_create have feedback on this? Thanks! -Brian Just a quick follow-up on this question of using an HSM (or in general, some form of Key Management Infrastructure) to sign TF-A images. U-Boot has support for this with its mkimage utility (see https://github.com/u-boot/u-boot/blob/master/doc/uImage.FIT/signature.txt#L5...). This appears to a custom engine in OpenSSL (and in this case, the pkcs11 engine). My questions are: 1. Does TF-A’s cert_create tool support using custom OpenSSL engines? 2. If so, is there a procedure for using this? 3. If not, is there a plan to add support for this in the roadmap somewhere? * Or, in general, is there a plan to add HSM support for TF-A image signing?

Minimal kernel/firmware on Rock64 (rk3328)

by Robert Meissner

Hello, i found TF a very interesting project, however I would like to get booted with a really minimal firmware/kernel. I have a Rock64 with RK3328 Rockchip which I am trying to boot from sdcard with following sources: https://gitlab.com/jahro_me/sos/-/tree/master/ I have tried to setup UART for the device as described in the manual https://opensource.rock-chips.com/images/9/97/Rockchip_RK3328TRM_V1.1-Part1… On page 13 it states, the BOOT_ROM, INT_RAM is located at 0xffff0000. I have used this adress in kernel_entry https://gitlab.com/jahro_me/sos/-/blob/master/boot.s and in the main section https://gitlab.com/jahro_me/sos/-/blob/master/link.lds However, I could not get the kernel booted. I am not sure, if I need to remap the memory and how to do it. I guess, i should enable it with SGRF_SOC_CON2. Could anyone please help out to get the output, "Hello, You Rock!"? Best regards, Bob

PSCI OS-initiated mode

by Wing Li

Hi, The PSCI specification defines two different power state coordination modes for CPU_SUSPEND that can be used to put a core or a group of cores into a low-power state. These modes are the platform-coordinated mode (default) and the OS-initiated mode (optional). OS-initiated mode is currently not supported by TF-A, while both modes are supported by the Linux Kernel. Requesting reviews for the patches [1] adding support for OS-initiated mode in TF-A and the corresponding tests in TF-A-Tests. Any feedback and comments are much appreciated. Thanks in advance!

Announcing TF-RMM v0.1.0

by Soby Mathew

Hi Everyone The TF-RMM team is pleased to announce the first public release of RMM implementation aligned to RMM Beta0 Specification [1] . The RMM is a software component that runs at Realm EL2 and forms part of a system which implements the Arm Confidential Compute Architecture (Arm CCA). The implementation can create Realm VMs in the Realm PAS and the Realm contents can be attested as specified in the RMM specification. The official trustedfirmware.org git repo can be found at : https://git.trustedfirmware.org/TF-RMM/tf-rmm.git/. There is also a github read-only mirror and can be found at https://github.com/TF-RMM/tf-rmm . Contributions will be accepted via TF-RMM gerrit at trustedfirmware.org : https://review.trustedfirmware.org/q/project:TF-RMM%252Ftf-rmm Please see the readme [2] and the getting started guide [3] to get started with RMM. We expect patches for supporting Realm Management Extension (RME) in linux kernel and related kvm-unit-tests to be available in the coming months. The patch to exercise Realm creation and execution via TF-A-Tests is in review at the moment [4] and the OOB instructions for the same can be found in TF-A RME documentation [5]. We expect these patches to be part of the upcoming TF-A v2.8 release. The mailing list for the project is tf-rmm(a)lists.trustedfirmware.org<mailto:tf-rmm@lists.trustedfirmware.org>. Looking forward to fruitful community engagement and successful deployment Arm CCA systems in future. Best Regards Soby Mathew PS : We hope to setup readthedocs documentation in the coming days, but till then , please bear with the github rendering of the rst documentation. [1] https://developer.arm.com/documentation/den0137/1-0bet0/?lang=en [2] https://github.com/TF-RMM/tf-rmm/blob/main/docs/readme.rst [3] https://github.com/TF-RMM/tf-rmm/blob/main/docs/getting_started/getting-sta… [4] https://review.trustedfirmware.org/c/TF-A/tf-a-tests/+/17221 [5] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17610

V2.8 Release code freeze notification

by Joanna Farley

Hi all, As documented in the Release Cadence section of the TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…) the v2.8 release has an expected code freeze date of 3rd week of November 2022. That equates to the start of that week Monday 14th November which is one calendar month away from tomorrow when the rc0 tag will be applied. Closing out the release takes around 6-10 working days normally over the last few releases. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. Preparations for v2.8 release is already underway. Thanks Joanna

Conditional CMOs

by Okash Khawaja

Hi, When a core is in debug recovery mode its caches are not invalidated upon reset, so the L1 and L2 cache contents from before reset are observable after reset. Similarly, debug recovery mode of DynamIQ cluster ensures that contents of the shared L3 cache are also not invalidated upon transition to On mode. A common use case of booting cores in debug recovery mode is to boot with caches disabled and preserve the caches until a point where software can dump the caches and retrieve their contents. TF-A however unconditionally cleans and invalidates caches at multiple points during boot, e.g. in bl31_entrypoint when cleaning bss and .data sections. This will not only lose the cache content needed for debugging but will potentially corrupt memory as well, leading to bugs when booting in recovery mode. Can we make CMOs in lib/aarch64/cache_helpers.S conditional upon some platform hook to address above scenario? Happy to work on a patch if the idea of conditional CMOs makes sense. Thanks, Okash

Inconsistencies with PLAT_XLAT_TABLES_DYNAMIC

by Jeffrey Kardatzke

Hello, Is there a reason there are inconsistencies in the handling of PLAT_XLAT_TABLES_DYNAMIC? Specifically I'm referring to in some places it uses #ifdef logic: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/utils/… and then in others it's using #if: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/include/li… Also in some places it uses add_define: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/services/s… and in others it's explicitly adding the define (w/ or w/out a value) to the _FLAGS for an image. https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/plat/imx/i… https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/plat/arm/b… I wanted to make use of this config option and noticed it wasn't getting picked up even when it was set and was considering cleaning up the usage of it by adding it to make_helpers/defaults.mk and then changing all the #ifdef's for it to be #if's. Thanks, -- Jeffrey Kardatzke jkardatzke(a)google.com Google, Inc.

Re: 回复： building secure boot tf-a images without ROTK controlled by SW build engineer

by Neely, Brian

Hello, Just a quick follow-up on this question of using an HSM (or in general, some form of Key Management Infrastructure) to sign TF-A images. U-Boot has support for this with its mkimage utility (see https://github.com/u-boot/u-boot/blob/master/doc/uImage.FIT/signature.txt#L…). This appears to a custom engine in OpenSSL (and in this case, the pkcs11 engine). My questions are: 1. Does TF-A’s cert_create tool support using custom OpenSSL engines? 2. If so, is there a procedure for using this? 3. If not, is there a plan to add support for this in the roadmap somewhere? * Or, in general, is there a plan to add HSM support for TF-A image signing? Thanks, Brian

Making the first byte of the stack canary a NULL for better security

by zjw88282740＠gmail.com

Hello, After learning the current implementation of plat_get_stack_protector_canary in TF-A, i am curious about why we not make the first byte of canary an NULL byte for better security?

Debug RME feature on FVP_Base_RevC-2xAEMvA_11.19_14

by Ádám Tóth

Hello, I am about to debug RME feature with ARM DS on FVP_Base_RevC-2xAEMvA_11.19_14 platform. I am using the Trusted Firmware with RME extension based on this description https://trustedfirmware-a.readthedocs.io/en/latest/components/realm-managem… My observation is running plainly the model, everything looks ok, the VFP can run the SW without any problem. (I can see the consol windows with normal booting procedure) In case I would like to set up the ARM debugger in ARM DS, the simulation immediately stops after start with a popup window: "Unable to connect to device ARMAEM-a_MP_0 Error opening connection to device 16 Socket is closed(E_io_error) Socket is closed" Apparently my Debug settings are good: With the same settings I can run/debug the complete ARM Reference Solution (Linux, u-boot, TrustedFirmware) based on this description: https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs… but if I add additional flags for FVP: (-C cluster0.rme_support_level=2 -C cluster1.rme_support_level=2) I still can run the model, but cannot debug so when I activate the RME feature the ARM debugger do the previously mentioned behavior (stops right after start) How can I workaround this? What is the most efficient way to debug FVP with RME support. Any help is welcome here. Bye, Adam

回复： building secure boot tf-a images without ROTK controlled by SW build engineer

by Ben

Hi Xin, I my opion, it should base on product lifecyle phase. In development phase, the SW engineer can use dev ROT keys & certificates. ATF have tools to generate them. In deployment stage, use KMI to manage keys&certificates are more better.

Platform issues with mitigations of powerdown errata

by Boyan Karatotev

Hello everyone, There is a type of errata on a few CPUs where if they initiate a power down request which gets denied then attempting to power down again can fail in a deadlock. In essence, after the PE's power down sequence which ends on a WFI, but before actual power down, there exists a small window where an external event can interrupt the power down and cause the PE to continue after the WFI. Attempting to power down again after that can result in a deadlock. Affected CPUs are the Neoverse N2, Makalu ELP (Cortex X3), and Cortex A710. The SDEN [1] suggests to set the chicken bit CPUACTLR2_EL1[36] before the power down sequence and to clear it after coming out of the WFI (on anything other than RESET). The mitigations [2] set the bit in the `core_pwr_dwn` of each CPU but never clear it. This is because in the generic TF-A code path the WFI ends up being called in an infinite loop with the only way to come out of it being RESET. Most platforms with custom `pwr_domain_pwr_down_wfi` end up in the same loop or unrelated hardware reset mechanisms that avoid the errata. However, a few platforms could continue running as normal without going through a hardware reset which would require special treatment. The four problematic platforms are: * amlogic gxl and g12a: they fake a reset by manually calling the reset entrypoint on their primary CPUs only. This will leave the chicken bit set after reset. * socionext uniphier: same as amlogic but on all CPUs. * nxp (common code): I hope I understand what the platform is trying to do but there are 2 paths that raise an eyebrow: `_psci_sys_pwrdn_wfi` which has a single non-looped wfi (which could return as above) and `_psci_cpu_off_wfi` which seems to accept waking up as normal behaviour. The former path is a simple fix but the latter is the same case as amlogic and socionext. Due to its complexity I have not proposed any modification on either path. Finally, nvidia tegra and renesas (common code) have acceptable behaviour as far as the errata are concerned, however, they end up in the wfi loop only after a panic sequence. Although not problematic, this stands out. For all six platforms above there are a few options on how to proceed, the preferred one being to bring them in line with what everyone else does. Alternatively, ignoring the errata would be ok if these platforms never intend to use these CPUs. It must be noted, however, that it appears to be a family of errata, and these may not be all CPUs affected. [1]: the wording is identical for all 3 cores. For Neoverse N2: https://developer.arm.com/documentation/SDEN1982442/latest/ [2]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17157/1 Regards, Boyan

security: BL2 at EL3 on v8a based system

by sandeep tripathy

Hi, With the RME feature BL2 has to run at EL3 instead of EL1_S. EL3 has a separate PAS not accessible to EL1_S. Is there any harm in choosing to run BL2 at EL3 instead of BL2 at S_EL1 even for non-RME(v8a) systems? Given that EL3 and EL1_S have access to the same PAS. I am trying to revisit the motivation to run BL2 at EL1_S. I see there was an old discussion at https://github.com/ARM-software/tf-issues/issues/445 The reasoning was not pointing to any issue in specific but a generic principle of less permissiveness. Thanks Sandeep

Re: security: BL2 at EL3 on v8a based system

by Tripathy, Sandeep

Hi Manish, >>The existing name is more suitable for configuration where the platform has BL1 in it and BL2 can run at EL3 instead of S-EL1. Well, that is a minor thing to take care. V9 implementation does that in a way. >>This configuration is currently not available in TF-A but having this flexibility is not a bad idea and it can be platform's choice. That's my answer! And the default choice costs some memory with probably no increase in security (V8). >>BL31 can mask the secure world. Cant be done reliably on V8 (with root world V9 or EL2_S there is potential to compartmentalize the secure services as PAS isolation is feasible) Ex: EL1S can always overwrite the BL31 Xlat tables and take control of the vectors and many other ways depending on the platform. It's the same PAS! Thanks Sandeep

[PATCH TF-A] fix(plat/rcar3): Fix RPC-IF device node name

by Geert Uytterhoeven

According to the Generic Names Recommendation in the Devicetree Specification Release v0.3, and the DT Bindings for the Renesas Reduced Pin Count Interface, the node name for a Renesas RPC-IF device should be "spi". The node name matters, as the node is enabled by passing a DT fragment from TF-A to subsequent software. Fix this by renaming the device nodes from "rpc" to "spi". Fixes: 12c75c8886a0ee69 ("feat(plat/rcar3): emit RPC status to DT fragment if RPC unlocked") Signed-off-by: Geert Uytterhoeven <geert+renesas(a)glider.be> --- Background: On Renesas R-Car Gen3 platforms, the SPI Multi I/O Bus Controllers (RPC-IF) provide access to HyperFlash or QSPI storage. On production systems, they are typically locked by the TF-A firmware, unless TF-A is built with RCAR_RPC_HYPERFLASH_LOCKED=0. When unlocked, TF-A communicates this to subsequent software by passing a DT fragment that sets the "status" property of the RPC-IF device node to "okay". Unfortunately there are several issues preventing this from working all the way to Linux: 1. TF-A (and U-Boot on the receiving side) uses a device node name that does not conform to the DT specification nor the DT bindings for RPC-IF, 2. While U-Boot receives the RPC-IF enablement from TF-A, it does not propagate it to Linux yet, 3. The DTS files that are part of Linux do not have RPC HyperFlash support yet. This patch takes care of the first issue in TF-A. The related patches for U-Boot are [1]. Patches to enable RPC-IF support in Linux are available at [2]. Thanks for your comments!

Adding Openssl3 build capability to TF-A

by Gyorgy Szing

Hi, As you may know, the build system was changed, and the tip of master depends on Openssl3. This version is quite new and is not available in many old (or not so old) but still supported operating systems. (Ubuntu 18.04 is an example.) I made a quick and dirty fix to allow building Opessl3 right from TF-A if the source is pre-fetched. You can find this change here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16800 For our downstream project this is a perfect solution as the same component introducing the new dependency carries the solution. Thus, my build environment is not becoming TF-A version specific. From TF-A point of view the situation is not so simple. The above patch extends TF-A with "build environment provisioning" responsibility. Before this patch TF-A assumed, all "common" dependencies are available in the build environment, and this patch changes that. Yes, some strongly TF-A specific components were owned and built by TF-A, but openssl is different. Thus, my modification is a "game changer" in some ways. A few things to consider: * Openssl becomes a special kind of TPIP which the project will need to manage (e.g. look for security risks, version updates, compatibility to different OSs and OS versions, etc...). * This is a system wide component. There is a risk of breaking something the build uses. Hidden things like a python module depending on openssl and now picking up an incompatible version. * This change might be considered as layer bleeding since it "melds" responsibilities of the TF-A project and the "owner of the build environment". IMHO this might be a significant difference from supply-chain security perspectives. There are alternatives which might be considered better: * making the build system and host side tooling (e.g. cert_tool) backwards compatible with openssl2 * hosting pre-built static binaries somewhere, which would simplify build environment updates As I mentioned above, this is a "good enough" fix for my use-case, but not sure if this is the right approach from TF-A perspectives. I am happy to tidy up this patch and push it trough the review, but the efforts needed to implement "other options" are beyond my capacity. I am looking for feedback both from TF-A maintainers and from "build environment owners". Thanks! /George Ps.: Apologies for not doing "my homework". I know there is a ticket somewhere in Phabricator and I did not invest the needed time to find it.

Finally, a TF-A LTS Proposal!

by Okash Khawaja

TL;DR: Attached is the TF-A LTS proposal doc. Please review and share your thoughts. Hello everyone, Long term support for TF-A has a long history. As a community we have flirted with it for a while, and like any flirtation, it started with gossip -- in our case, over mailing list [1] -- more than two years ago. Then Varun Wadekar did a wonderful tech forum presentation [2] which demonstrated interest in the topic and raised interesting questions about LTS. After some time, the affair lost headline status, only to be revived again [3], earlier this year. This time however, there is a formal proposal (no pun intended). After the mailing list discussion and feedback from TF-A tech forum [4], we have put together a draft which attempts to give a concrete idea about what the TF-A LTS will look like. Please spare some time to read through it and share your feedback. The plan is to put LTS into action this November. Cheers! Okash [1] https://lists.trustedfirmware.org/archives/search?mlist=tf-a%40lists.truste… [2] https://www.trustedfirmware.org/docs/TF-A-LTS.pdf [3] https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… [4] https://www.trustedfirmware.org/docs/TForg_LTS_proposal.pdf

Issue with adding ssh key to review server

by sparlane＠gmail.com

Hi All, Sorry if this is the wrong list, I'm trying to submit a patch for tf-a and I'm currently unable to add an ssh key or generate an https password to use for authentication. Perhaps I am doing something wrong? I'm trying to use the settings here: https://review.trustedfirmware.org/settings/#HTTPCredentials to add an ssh key and I get the error message "Error 500 (Server Error): Internal server error Endpoint: /accounts/self/sshkeys" Any help is greatly appreciated. Thanks, Scott (sparlane)

How to trap aborts caused by TZASC?

by Chenxu Wang

Hi all, I want to test how to trap the aborts caused by TZASC. For example, when I use NS-EL1 (e.g., OS) to access a Secure region (configured in TZASC), it will generate an abort. But I am not sure how to trap it. I think it is an external abort, so I enable the SCR_EL3.EA=1 and write a handler. However I cannot trap it. Also, my other handlers in EL3 still do not report the abort. Thus, how can I trap a TZASC abort? If I want to route it into EL3 to handle, how can I do it? Sincerely, WANG Chenxu

Does FVP and current TF-A support the SVE/SVE2 programming?

by Chenxu Wang

Hi all, I want to perform some encryption/decryption in TF-A. I find that Arm provides some hardware-assisted instructions for encryption and integrity verification (e.g., AESE, SHA1...). But it seems that FVP does not support them. I recently read Armv9 and know that Arm purposes SVE/SVE2 to accelerate the matrix computation. It seems that it can be another approach to accelerate the encryption. Since I am a novice in Armv9 (and in FVP), thus, I want to ask: (1) Do FVP and TF-A support the SVE? If yes, how to configure it? (2) Do FVP and TF-A support the SVE2? If yes, how to configure it? Looking forward to your reply! Sincerely, WANG Chenxu

Hi Glen, Don, and others, I've seen that a couple of TF-A patches I've been CCed on recently often seem to fail the CI run (Allow-CI+1) due to some strange build-time errors that don't seem to have anything to do with the patch at hand, and then one of the maintainers usually suggests that the patch needs a rebase, and the next CI run succeeds after that. Here are two recent examples: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16160 https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14666 I was wondering if this is a known problem and if the CI can do anything here to mitigate it and save developers from this extra layer of friction? I'm not really sure why a rebase was necessary in either of these examples or why the CI run failed before it (unless the whole repository was in a bad state that didn't build, but since all submissions are guarded by the CI that shouldn't have been possible?). But I also don't really understand why the rebase would make a difference for the CI anyway. Generally, when a patch is submitted in Gerrit, that means it is cherry-picked onto the current master (regardless of what parent commit it was uploaded with). Since the CI is supposed to be a test run for submission, I would expect that the CI should also test a patch by cherry-picking it onto the current master, not just by building the patch on top of whatever parent commit it was uploaded with. But since rebasing a patch evidently seems to make a difference to the CI, that suggests that it's currently doing the latter strategy? Should that maybe be changed to the former to avoid these kinds of issues? If this isn't a known problem yet maybe it would be worth adding it to the JIRA? Thanks, Julius

A problem about TZASC in Armv9

by Chenxu Wang

Greetings, Armv9 introduces the RME and GPT technology. The GPT will separates the memory into unlimited regions with specific attributes. However, when I read the Armv9 manual and source code of TF-A, I still have some problems: 1. It seems that GPT is a feature on CPU, but not on a specific device (e.g.,TZC-400). Thus, will GPT conflict with TZC-400? I mean, when performing VA->PA on RAM, what is the detailed process if I enable both GPT and TZC-400? 2. I use the Arm FVP with Armv9 and RME extension enabled, and TF-A is "arm_cca" branch (with TF-A v2.5). Thus, in this version, what is the configuration for TZC-400 and GPT? Will it disable TZC-400 (I mean, GPT only) when booting Normal World? 3. Does GPT handle peripheral access (e.g., from DMA, GPU, Sensors... etc.)? I know TZC-400 will do it with NSAID. 4. Will GPT configures Read/Write/Execute features? All comments are valuable! SIncerely, WANG Chenxu

Re: Question about disable MMU in BL1

by 邬金平

Hi, I have tried this before, there is a problem. on Armv8, when MMU disabled, the default attribute of memory is device, and device memory access has alignment requirements. For example, accessing address (0x1) will result in fault.

Question about maximum TF-A BL31 memory usage

by Peng Fan

Hi All, Is there any public BL31 memory usage data, such as static image size and runtime memory usage, with different feature enabled? For example, typical PSCI feature would require image size XXKB, runtime memory XXKB. enabling FFA would enlarge image size by XXKB, runtime memory enlarge XXKB. we are evaluating how much On-Chip RAM could be assigned for BL31, if there are any public data available, that would be great. Thanks, Peng.

Rebooting LTS discussion

by Okash Khawaja

Hi, There have been discussions about having long term support releases for TF-A, e.g. the email thread [1] and a tech forum [2]. For partners releasing TF-A in their production devices, LTS is very much needed. From the previous discussions, it seems like there is an agreement that LTS is a good idea but we need to build consensus on how to support it. Any thoughts on this? Thanks, Okash [1] https://lists.trustedfirmware.org/archives/search?mlist=tf-a%40lists.truste… [2] https://www.trustedfirmware.org/docs/TF-A-LTS.pdf

Question about FVP's dts

by Chenxu Wang

Hi all, I am using FVP base RevC. Recently I heard that this FVP supports a Mali G76 GPU, and I want to test it. To configure it, initially I add a node in linux/arch/arm64/boot/dts/arm/fvp-base-aemv8a-aemv8a.dtsi, but it doesn't work. Finally, I find that I should configure trusted-firmware-a/fdts/fvp-base-gicv3-psci-1t.dts, and I can see a mali GPU node in /proc/device-tree. One of my booting command (sorry, the entire booting command is TOO long) is "--data cluster0.cpu0=arm-reference-platform/output/fvp/fvp-oe/uboot/fvp-base-aemv8a-aemv8a.dtb@0x82000000". And I use the following shell command to compile the TF-A: make PLAT=fvp all CROSS_COMPILE=aarch64-none-elf- ENABLE_RME=1 DEBUG=1 ARCH=aarch64 fip BL33=arm-reference-platform/output/fvp/components/fvp/uboot.bin FVP_HW_CONFIG_DTS=fdts/fvp-base-gicv3-psci-1t.dts ARM_DISABLE_TRUSTED_WDOG=1. So, I wonder, why the real DTS is in TF-A, instead of Linux? BTW, I wanna ask another question (although it is not proper to ask here, I cannot find FVP's mailing list): Can someone provide a proper dts configurations for FVP's Mali G76 GPU? Sincerely, WANG Chenxu

Re: Cannot successfully jump to the UEFI Boot Loader in the normal world with the RME enabled FVP_Base_RevC_2xAEMvA

Addition of write() capability to IO MTD layer

by brian.neely＠analog.com

Hello, A project I’m working on requires write capability for a NOR flash device in BL2 (to update a small boot mux partition). I am considering adding this capability to the IO MTD layer (https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/io…), but before doing so wanted to confirm this is in line with the architecture of this subsystem. Can someone confirm if this is an acceptable change? Regards, Brian

Version 1.2.12 of zlib was released

by mikemcternan＠google.com

Hi! It looks like TF-A contains zlib 1.2.11 e.g. https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/zlib/z… zlib.net gives their last release as 1.2.12 (March 27, 2022) with the following changelog: "Fix a deflate bug when using the Z_FIXED strategy that can result in out-of-bound accesses. Fix a deflate bug when the window is full in deflate_stored(). Speed up CRC-32 computations by a factor of 1.5 to 3. Use the hardware CRC-32 instruction on ARMv8 processors. Speed up crc32_combine() with powers of x tables. Add crc32_combine_gen() and crc32_combine_op() for fast combines. Due to the bug fixes, any installations of 1.2.11 should be replaced with 1.2.12." I'm not sure if this is significant as I couldn't find usages of deflate, but thought I would mention it in case others are relying on this functionality and wish to update. Kind regards, Mike

synopsis emcc adma2/3 modes

Hello all, I need to load Bl2 boot image file from emmc interface from 'Synopsys DesignWare Cores Mobile Storage Host Controller'. I can see an existing emmc driver for synopsis controller but it seems to have only support SDMA mode and not ADMA2 and ADMA3 modes. https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/sy… Is my understanding correct. Is there a specific reason why ADMA2/3 modes are not supported in existing driver. Any plan to update them soon?

Measured boot and external TPM modules

by Ramon Fried

Hi, I'm currently working on porting TFA to our upcoming SOC. We plan to support Measured boot using external I2C TPM module. I'm wondering about the implementation of that in BL1. Do you think that I need to write the measurements directly to the I2C module in BL1 ? I'm asking because I would like to have the least source of problems in BL1 which I can't upgrade. I thought of storing the measurements in secure RAM and perhaps copy later. Would love to hear your thoughts. PS. Actually I would love to have the option to choose to implement TPM also in SW (fTPM using optee - as was done in the POC). I think that if I store the measurement of BL2 in secure RAM I can later change the specific TPM while upgrading only BL2/BL31... Thanks, Ramon

[REGRESSION] v2.7-rc0 broken for STM32MP boards: lxa-mc1, avenger96, odyssey

by Ahmad Fatoum

Hello Yann, Hello Pascal, I've tried booting v2.7-rc0 on the lxa-mc1 and TF-A panics: NOTICE: CPU: STM32MP157C?? Rev.B NOTICE: Model: Linux Automation MC-1 board ERROR: regul ldo3: max value 750 is invalid PANIC at PC : 0x2ffeebb7 because the driver takes great offense at the content of the device tree. The parts in question were copy-pasted from ST DTs, but those ST DTs were fixed by commit 67d95409baae ("refactor(stm32mp1-fdts): update regulator description"). I can understand ST hesistancy to touch device trees of 'unofficial' boards, but I would appreciate that new features then, such as this regulator sanity checking, be made optional and off by default to not needlessly break other boards. Thanks, Ahmad -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |

Floating point math

by Bartus, Dan

We are using an arm ARCH-64 (A55) and we need to do some floating point math in BL2. It seems this is not enabled. Is there a reason why I cannot do FP math (security issue?) and if I can, how do I enable it? I am seeing this error when I use floats "-mgeneral-regs-only" thanks

[Question] fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57

by JY Ho (何駿彥)

Dear Sirs, I’m TF-A developer of MediaTek and have a situation of CVE patch (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298) with CA73. In CA73 platform with 64-bit TF-A v2.4 and 64-bit OP-TEE v3.16, system will occur halt during boot flow after we applied fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298>. We used ICE to trace boot flow step by step, and found S-EL1 will ask EL3 its SMC_VERSION. In the fastcall, TF-A will execute wa_cve_2017_5715_bpiall_vbar()<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298/11/lib…> which back up some setting and switch processor from AArch-64 to AArch-32 and does BPIALL<https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14298/11/lib…>. But AArch32 cannot access and run over than 4G bus address without LPAE. (Suppose the TF-A and OP-TEE are locate on over than 4G bus address.) Maybe can we replace AArch32_stub with IC IALLU ? Or add LPAE setting before do AArch32_stub? (I don’t know it make sense or not) Thank you. JY

imx8mn and HAB

by Heiko Thiery

Hi, We use mainline TF-A and have problems using the HAB API in the U-Boot. We see for example that the hab_auth_img command fails in the mainline U-Boot. If we switch to the downstream NXP TF-A it works. Is this to be expected? -- Heiko

Issue about passing arguments between the BL1 and BL2 in Arch32

by 邬金平

Hi Arguments between the BL1 and BL2 is overlap by zeromem when BL2 start. 1. BL2 save r3 to r12 arm-trusted-firmware/bl2/aarch32/bl2_entrypoint.S /*--------------------------------------------- * Save arguments x0 - x3 from BL1 for future * use. * --------------------------------------------- */ mov r9, r0 mov r10, r1 mov r11, r2 mov r12, r3 2. BL2 call zeromem to clear bss arm-trusted-firmware/bl2/aarch32/bl2_entrypoint.S ldr r0, =__BSS_START__ ldr r1, =__BSS_END__ sub r1, r1, r0 bl zeromem arm-trusted-firmware/lib/aarch32/misc_helpers.S tmp .req r12 /* Temporary scratch register */ r12 used as scratch register 3. r3 restore from r12 arm-trusted-firmware/bl2/aarch32/bl2_entrypoint.S mov r0, r9 mov r1, r10 mov r2, r11 mov r3, r12 I can try to save it in other registers, but can not guarantee that the register will not be damaged. Is there any better way to deal with this problem? Thanks.

ECLAIR for static analysis

by Varun Wadekar

Hi @Joanna<mailto:Joanna.Farley@arm.com>, I am glad that tf.org has taken this step to improve code quality with the latest announcement [1]. Some questions to understand the model a bit better. 1. Is the tool available to the community? 2. Can people run this before submission? Or is it restricted to a certain group? 3. Will full reports be released to the community? 4. What will the deployment model look like? I suggest we discuss this in a tech forum to reach the entire community. -Varun [1] https://www.trustedfirmware.org/news/BugSeng_press_release/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.trust…> https://www.bugseng.com/eclair<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.bugse…> https://www.bugseng.com/sites/default/files/resources/ECLAIR_TUV-SUD_Certif…<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.bugse…>

Trusted Firmware-A v2.7 release activities in May

by Daniel Boulby

TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.7 release during the 4th week of May as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.6 release. As part of this, a release candidate tag will be created and release activities will commence from 23rd May across all TF-A repositories. Essentially, we will not merge any major enhancements from this date until the release is made. Please ensure any patches desired to make the 2.7 release are submitted in good time to be complete by 20th May. Any major enhancement patches still open after that date will not be merged until after the release. This will involve the various repositories making up the broader TF-A project including the TF-A mainline, TF-A Tests, Hafnium, TF-A CI Scripts and TF-A CI Jobs. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start. Thanks, Daniel

Issue in HW config consumption by secure BL components

by Manish Badarkhe

Hi All, Currently, in Arm platforms, BL2 loads HW config in the non-secure memory so that it can be consumed by both non-secure components (BL33) and secure (BL31, BL32) components. In most cases, this shouldn't be an issue since no software runs in non-secure world at this time (i.e. non-secure world has not been started yet) However, it doesn't provide a guarantee though since any malicious external NS-agents (such as an external debugger)can take control of this memory region for update/corruption after BL2 loads this region and before BL31 consumes it. Consider below scenario: 1. BL2 loads HW_CONFIG from flash to NS DRAM. 2. BL2 authenticates HW_CONFIG in NS DRAM. 3. A malicious non-secure agent modifies the contents of HW_CONFIG in NS DRAM, such that it induces a different behaviour in BL31. 1. BL31 consumes HW_CONFIG without noticing it has changed. To overcome this issue, I created a patch [1] to load the HW-config into secure memory, and that eventually will be used by BL31/sp_min and BL32 components. Additionally, BL31/sp_min copies the HW-config present in secure memory to a non-secure location before passing it on to BL33. In order to accomplish this, mapped secure DRAM in BL31/sp_min and BL32, and non-secure DRAM in BL31/sp_min. I believe some platforms may have similar kind of issue i.e. HW config placed in non-secure memory consumed by both secure and non-secure components. It is appreciated if you review the patch [1] I posted and provide feedback. This patch [1] also mitigates threat ID #3 for FVP platform as per the TF-A threat model [2] (Bypass image authentication scenario).

Trusted Firmware-A v2.7 release activities in May 2022

by Joanna Farley

TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.7 release during the fourth week of May 2021 as part of the regular 6 month cadence. This is a little later than originally targeted due to the number of patches still under review from contributors. The aim is to consolidate all TF-A work since the 2.6 release. As part of this, a release candidate tag will be created and release activities will commence some time during the week ending 20th May 2022 across all TF-A repositories. Any major enhancement patches still open after that date will not be merged until after the release. This release will involve the various repositories making up the broader TF-A project including the TF-A mainline, TF-A Tests, Hafnium, TF-A CI Scripts and TF-A CI Jobs. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start. Thanks Joanna

Status of MTE for bl31

by Okash Khawaja

Hi, I wanted to check the status of MTE support for bl31 itself. It seems like the support was added [1] for clang and armclang but I couldn't find the memory attribute to map pages as tag checked [2]. Is there something I missed? Thanks, Okash [1] https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/… [2] https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/…

MTE support at S-EL1

by Jens Wiklander

Hi, I've started to experiment with MTE in OP-TEE at S-EL1. I've compiled TF-A with CTX_INCLUDE_MTE_REGS and I'm testing this on QEMU. Before trying to use MTE in OP-TEE I check id_aa64pfr1_el1 and skip MTE initializations if unavailable. This works as long as TF-A always is compiled with CTX_INCLUDE_MTE_REGS if MTE is available. If TF-A is compiled without CTX_INCLUDE_MTE_REGS OP-TEE will be trapped into EL3 when trying to access one of the MTE registers. I suppose this is because SCR_EL3.ATA is 0. Is there a way for OP-TEE to tell if the MTE registers are safe to access? Thanks, Jens

TF-a would not handle PSCI_CPU_ON_AARCH64 if forwarded by a hypervisor

by Mushahid Hussain

Hi, I'm working on a hobby project: AARCH64 Hypervisor on Raspberry Pi 4b. I have a problem with trapping a psci smc. I'll explain everything and what steps I have followed. Right now, I'm implementing SMC trapping. I can successfully forward almost all SMCs except for PSCI_CPU_ON_AARCH64. Linux makes these SMCs to bring up secondary CPUs during booting. Here's what I'm trying to do: - trap the PSCI_CPU_ON_AARCH64 SMC, - preserve the entry_point address in global variable - replace the entrypoint with my entrypoint and make the smc to tf-a(or simply forward it.) - when secondary cpus come online at the given address, where I set their stack point and then eret the original address. Secondary cpus won't come online at the given address. Even if I don't change any arguments of CPU_ON smc and forward it as it is, the secondary cpus still won't come online. However, without trapping enabled(HCR_EL2.TSC=0), everything works fine. I tried to debug inside Trusted Firmware. I know that overall path for secondary CPU hotplug in is: CPU released from reset -> (ROM and possibly some other bootloader) -> bl31/aarch64/bl31_entrypoint.S:bl31_warm_entrypoint() -> lib/psci/psci_common.c:psci_warmboot_entrypoint() -> lib/psci/psci_on.c:psci_cpu_on_finish() -> rpi3_pwr_domain_on_finish() I printed at all these points in Trusted Firmware with and without trapping enabled. Here's what I found: Nothing gets printed anywhere in that path if trapping is enabled. However, without trapping enabled, I can print anywhere even in bl31_entrypoint.S:bl31_warm_entrypoint(). What could be the problem? Here's my code: https://github.com/SikkiLadho/Leo/blob/4f272eff39934058a7f989c91aad82eab810… -- Mushahid Hussain

Cortex-X1 support

by Okash Khawaja

Hello, Are there any immediate plans to add support for Cortex-X1 in TF-A? If not then I'll be happy to submit CL for it. For start, it will cover a subset of errata workarounds. Then people can add more as needed. Let me know what you think. Thanks, Okash
