TF-A Tech Forum Sessions Jan/Feb

by Joanna Farley

Hi all, With the start of the new year I’m looking to see what TF-A Techforums should cover over the next few sessions. As folks may know these are held every two weeks on a Thursday at 4pm GMT. If you need an invite do reach out to me. If folks have anything they would like to present to the TF-A community please do reach out to me as we often need topics. If we don’t have anything to present on upcoming sessions I will cancel the sessions the day before they are due to be held. Currently I tentatively have the following for the first 4 sessions which will be confirmed nearer the dates: * 12th January – No topic * 26th January – LTS Update * 9th February – No topic * 23rd February - Tech talk for PSCI OS-initiated mode Thanks Joanna

Runtime loading of SEL-1

by Jeffrey Kardatzke

Hello, I'm working on a project for ChromeOS where we would like to be able to load the BL32 payload (OpTee) for SEL-1 after the linux kernel has booted rather than during the usual BL32 stage. We would do this via an SMC we would add which would take the OpTee image from linux and then have EL3 load it and perform the init for SEL-1 at that time. The reasoning behind this is that it's much easier to update the rootfs than the FW on our devices, and we can still ensure the integrity of the OpTee image if we load it early enough after the kernel boots. The main questions I have are if there are any issues people would be aware of by loading it after linux boots rather than during the usual BL32 stage? And I would definitely want to upstream this work if it's something we can do. Thanks, Jeffrey Kardatzke Google, Inc.

Question about using rme for smmuv3

by Chenxu Wang

Hi all, I test the SMMUv3 on FVP_Base_RevC-2xAEMvA_11.20_15, and my TF-A is the branch "arm_cca_v0.3". When I boot my FVP, I set the following commands: -C pci.pci_smmuv3.mmu.SMMU_ROOT_IDR0=3 \ -C pci.pci_smmuv3.mmu.SMMU_ROOT_IIDR=0x43B \ -C pci.pci_smmuv3.mmu.root_register_page_offset=0x20000 \ -C cluster0.rme_support_level=2 \ -C cluster1.rme_support_level=2 \ Based on the FVP manual, the SMMU base is 0x2b40_0000, and I think the SMMU Root Control Page should be 0x2b42_0000. Thus, I add the mapping to this region in plat_arm_mmap[], as: MAP_REGION_FLAT(0x2b420000,(0x2b430000-0x2b420000),MT_MEMORY | MT_RW |MT_ROOT) Then I try to access the SMMU_ROOT_IDR0 register in TF-A. Based on the manual, its offset is 0x0, so I read 0x2b42_0000. However, it returns 0x0, which is not what I configured in the boot commands (I think it should be 0x3). Can someone tell me the reason for this? Sincerely, WANG Chenxu

Upcoming "Stricter ASN.1 certificate parsing" patches

by Sandrine Bailleux

Hello everyone, I'd like to draw your attention on the following patch stack (contribution from Demi Marie Obenour, thank you!): https://review.trustedfirmware.org/q/owner:demiobenour%2540gmail.com+is:open These patches refactor the X.509 certificate parser leveraged by the trusted boot implementation in TF-A, such that the parser more closely follows the X.509 format specification [1] and ASN.1/DER encoding rules [2]. In a nutshell, this means that the X.509 parser is now stricter. Some ill-formatted certificates which TF-A would have previously accepted are now rejected. All trusted boot tests in the TF-A OpenCI have passed with these patches but I realize that this does not cover all platforms and use cases. Thus, I'd like to allow time for all platform maintainers that wish it to conduct their own testing and report any issue they're seeing on the mailing list. If we don't hear anything by end of Wednesday (14/12), we'll merge the patches. Best regards, Sandrine [1] See RFC5280, https://datatracker.ietf.org/doc/html/rfc5280 [2] ITU-T X.690, https://www.itu.int/ITU-T/studygroups/com10/languages/X.690_1297.pdf

[PATCH] fix(console): fix crash on spin_unlock with cache disabled

Supporting QEMU in OpenCI

by Harrison Mutai

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!

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?

TF-A TechForum this week

by Joanna Farley

Hello TF-A Community, The meeting invite this week has been updated with an agenda. In case you have not seen this the details are: The TF-RMM component was published last week and was announced in this mailing list: https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… This week Javier Almansa Sobrino of the TF-RMM team would like to present on the TF-RMM Unit test framework The TF-RMM Unit test framework allows the exercising and validation of the software components of TF-RMM to be performed natively on the development host, making the development of new features, as well as the debugging of existing ones, easier. This talk will introduce this framework as well as the fake_host architecture for TF-RMM which allows the building and running of TF-RMM natively on the development host. We will also discuss how to implement unit tests for different components and we will introduce some features such as code coverage test for TF-RMM.

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
