TF-A TechForum this Thursday 3rd November at 4pm GMT

by Joanna Farley

Hi Everyone, We have a TF-A Tech forum scheduled for this Thursday at 4pm GMT. Note the UK clocks moved to GMT from BST last weekend so the meeting may appear an hour different than in previous weeks in your calendar. At this time I do not have any topics to present. Please do reach out to me if you have any topics you would like to present to the TF-A community. If I do not find a topic or hear from the community that they have a topic I will cancel end of day this coming Wednesday 2nd November. Thanks Joanna

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. BRs,Ben ----------回复的邮件信息---------- Xin.Xu--- via TF-A<tf-a(a)lists.trustedfirmware.xn--org> 2022-10-19-jw84b 周三 23:56写道： product ROT private key is controlled by KMI team. our plan is (1) SW build engineer builds  tf-a with a temporary development ROT key, save all other generated keys (2) remove fip image and all certificates built, send build images and generated keys to KMI team (3) KMI team uses cert_create to re-generate all certificates with product ROTK (4) KMI team sends all images, certificates, ROTPK hash to SW build engineer (5)  SW build engineer uses fiptool to generate final fip image my question: is there a better way to deal with this situation? (SW build engineer doesn't have control of ROT key) Thanks -Xin -- TF-A mailing list -- tf-a(a)lists.trustedfirmware.org To unsubscribe send an email to tf-a-leave(a)lists.trustedfirmware.org
