So, now is a good time to start testing the master branch on the various platforms and report/fix any bugs. The GitHub pull request for collecting Tested-by tags or any other comments is https://github.com/OP-TEE/optee_os/pull/6125. As usual, we will create a release candidate tag one week before the release date for final testing. In addition to that you can find some additional information related to releases here: https://optee.readthedocs.io/en/latest/general/releases.html Regards, Joakim Bech (*) We moved this from July 14th to July 7th due to vacation and holiday schedules.

[RFC PATCH 1/1] tests/avocado: Introduce avocado tests for aarch64 S-EL2 booting

by shiju.jose＠huawei.com

From: Shiju Jose <shiju.jose(a)huawei.com> Add avocado tests for aarch64 S-EL2, include booting and run xtest on linux terminal. The prebuilt S-EL2 images are corresponding to the https://github.com/jenswi-linaro/manifest.git \ -m qemu_v8.xml -b qemu_sel2 How to run ========== "make check-avocado" in qemu/build or with QEMU_CI=1 and QEMU_CI_AVOCADO_TESTING=1 "amd64-fedora-container", "build-cfi-aarch64" and "avocado-cfi-aarch64" on gitlab for qemu Question: Presently tested with the prebuilt images temporarily in /tests/data/sel2-boot-images/prebuilt-sel2-images.zip Can the prebuilt images for SEL2 available in the OP-TEE/TF-A/similar release? Note1: The pre-built S-EL2 images used are few months old as there are some issue found in xtest with the images build from the recent Linaro SEL2 code. Note2: On gitlab CI, there is an outstanding issue found in booting linux, after starting network OK.

Linaro OP-TEE Contribution, LOC, monthly meeting June 27

by Jens Wiklander

Hi, On Tuesday, June 27 it's time for another LOC monthly meeting. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ I'd like to discuss how MbedTLS is used in OP-TEE. While trying to update to MbedTLS 3.4 on the 4.x WIP branch [1] we have run into yet another issue with the CRT parameters used in the RSA implementation. See [2] for more details on the CRT problem. [1] https://github.com/jenswi-linaro/optee_os/tree/wip_4_0_0 [2] https://github.com/jenswi-linaro/optee_os/pull/9 any other topics? Thanks, Jens

PKCS11 TA: MR https://github.com/OP-TEE/optee_os/pull/5166

by dourlent cédric

Hi, I contact you about the merge request https://github.com/OP-TEE/optee_os/pull/5166 that is mandatory to be able to use ECC private key imported in PKCS11 TA and not generate by the TA. Currently the status is Attribute on generated ECC private key are - EC_PARAMS - VALUE - EC_POINT => This object can be use for crypto operation Attribute on imported ECC private key are - EC_PARAMS - VALUE => PKCS11 TA can not use it because TA expect EC_POINTS attributes on ECC Private key. Could you accept the merge request and have a coherence between generated and imported object even if for the moment it's doesn't respect PKCS11 standard ? Two options for the next step. - check with PKCS11 editors to upgrade the spec and have a same behavior between RSA Private object and ECC Private object. - rework the code of the TA for ECC to link Private and public object but that mean that ECC Private and Public object must be present in the same slot to be able to perform crypto operation. Best regards, Cédric Dourlent,

reference keymint & gatekeeper TAs

by Nagendra Modadugu

I'm writing to get further information regarding the support roadmap for OP-TEE based TA's - specifically keymint and gatekeeper. The implementations I could find are here: https://github.com/linaro-swg/kmgk, and was wondering whether these are supported? Please respond off list if you find that would be more appropriate for discussion. thanks.

[PATCH v2 0/4] rpmb subsystem, uapi and virtio-rpmb driver

by Shyam Saini

Hi Alex, [ Resending, Sorry for the noise ] Are you still working on it or planning to resubmit it ? [1] The current optee tee kernel driver implementation doesn't work when IMA is used with optee implemented ftpm. The ftpm has dependency on tee-supplicant which comes once the user space is up and running and IMA attestation happens at boot time and it requires to extend ftpm PCRs. But IMA can't use PCRs if ftpm use secure emmc RPMB partition. As optee can only access RPMB via tee-supplicant(user space). So, there should be a fast path to allow optee os to access the RPMB parititon without waiting for user-space tee supplicant. To achieve this fast path linux optee driver and mmc driver needs some work and finally it will need RPMB driver which you posted. Please let me know what's your plan on this. [1] https://optee.readthedocs.io/en/latest/architecture/secure_storage.html Best Regards, Shyam
