[PATCH 0/2] small amdtee cleanups

by Mario Limonciello

From: Mario Limonciello <mario.limonciello(a)amd.com> I just noticed a few small things for amdtee where the error messages didn't consistently use the driver name. While fixing that I noticed the headers weren't sorted. These patches fix both issues.

[PATCH v7 00/11] TEE subsystem for protected dma-buf allocations

by Jens Wiklander

Hi, This patch set allocates the protected DMA-bufs from a DMA-heap instantiated from the TEE subsystem. The TEE subsystem handles the DMA-buf allocations since it is the TEE (OP-TEE, AMD-TEE, TS-TEE, or perhaps a future QTEE) which sets up the protection for the memory used for the DMA-bufs. The DMA-heap uses a protected memory pool provided by the backend TEE driver, allowing it to choose how to allocate the protected physical memory. The allocated DMA-bufs must be imported with a new TEE_IOC_SHM_REGISTER_FD before they can be passed as arguments when requesting services from the secure world. Three use-cases (Secure Video Playback, Trusted UI, and Secure Video Recording) has been identified so far to serve as examples of what can be expected. The use-cases has predefined DMA-heap names, "protected,secure-video", "protected,trusted-ui", and "protected,secure-video-record". The backend driver registers protected memory pools for the use-cases it supports. Each use-case has it's own protected memory pool since different use-cases requires isolation from different parts of the system. A protected memory pool can be based on a static carveout instantiated while probing the TEE backend driver, or dynamically allocated from CMA and made protected as needed by the TEE. This can be tested on a RockPi 4B+ with the following steps: repo init -u https://github.com/jenswi-linaro/manifest.git -m rockpi4.xml \ -b prototype/sdp-v7 repo sync -j8 cd build make toolchains -j$(nproc) make all -j$(nproc) # Copy ../out/rockpi4.img to an SD card and boot the RockPi from that # Connect a monitor to the RockPi # login and at the prompt: gst-launch-1.0 videotestsrc ! \ aesenc key=1f9423681beb9a79215820f6bda73d0f \ iv=e9aa8e834d8d70b7e0d254ff670dd718 serialize-iv=true ! \ aesdec key=1f9423681beb9a79215820f6bda73d0f ! \ kmssink The aesdec module has been hacked to use an OP-TEE TA to decrypt the stream into protected DMA-bufs which are consumed by the kmssink. The primitive QEMU tests from previous patch set can be tested on RockPi in the same way with: xtest --sdp-basic The primitive test are tested on QEMU with the following steps: repo init -u https://github.com/jenswi-linaro/manifest.git -m qemu_v8.xml \ -b prototype/sdp-v7 repo sync -j8 cd build make toolchains -j$(nproc) make SPMC_AT_EL=1 all -j$(nproc) make SPMC_AT_EL=1 run-only # login and at the prompt: xtest --sdp-basic The SPMC_AT_EL=1 parameter configures the build with FF-A and an SPMC at S-EL1 inside OP-TEE. The parameter can be changed into SPMC_AT_EL=n to test without FF-A using the original SMC ABI instead. Please remember to do %rm -rf ../trusted-firmware-a/build/qemu for TF-A to be rebuilt properly using the new configuration. https://optee.readthedocs.io/en/latest/building/prerequisites.html list dependencies needed to build the above. The tests are pretty basic, mostly checking that a Trusted Application in the secure world can access and manipulate the memory. There are also some negative tests for out of bounds buffers etc. Thanks, Jens Changes since V6: * Restricted memory is now known as protected memory since to use the same term as https://docs.vulkan.org/guide/latest/protected.html.

[PATCH v3 00/11] Trusted Execution Environment (TEE) driver for Qualcomm TEE (QTEE)

by Amirreza Zarrabi

This patch series introduces a Trusted Execution Environment (TEE) driver for Qualcomm TEE (QTEE). QTEE enables Trusted Applications (TAs) and services to run securely. It uses an object-based interface, where each service is an object with sets of operations. Clients can invoke these operations on objects, which can generate results, including other objects. For example, an object can load a TA and return another object that represents the loaded TA, allowing access to its services. Kernel and userspace services are also available to QTEE through a similar approach. QTEE makes callback requests that are converted into object invocations. These objects can represent services within the kernel or userspace process. Note: This patch series focuses on QTEE objects and userspace services. Linux already provides a TEE subsystem, which is described in [1]. The tee subsystem provides a generic ioctl interface, TEE_IOC_INVOKE, which can be used by userspace to talk to a TEE backend driver. We extend the Linux TEE subsystem to understand object parameters and an ioctl call so client can invoke objects in QTEE: - TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_* - TEE_IOC_OBJECT_INVOKE The existing ioctl calls TEE_IOC_SUPPL_RECV and TEE_IOC_SUPPL_SEND are used for invoking services in the userspace process by QTEE. The TEE backend driver uses the QTEE Transport Message to communicate with QTEE. Interactions through the object INVOKE interface are translated into QTEE messages. Likewise, object invocations from QTEE for userspace objects are converted into SEND/RECV ioctl calls to supplicants. The details of QTEE Transport Message to communicate with QTEE is available in [PATCH 10/10] Documentation: tee: Add Qualcomm TEE driver. You can run basic tests with following steps: git clone https://github.com/quic/quic-teec.git cd quic-teec mkdir build cmake .. -DCMAKE_TOOLCHAIN_FILE=CMakeToolchain.txt -DBUILD_UNITTEST=ON https://github.com/quic/quic-teec/blob/main/README.md lists dependancies needed to build the above.

Linaro OP-TEE Contribution, LOC, monthly meeting April 22

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time and connection details, see the calendar at https://www.trustedfirmware.org/meetings/ OP-TEE version 4.6.0 is expected to be released on Friday, April 25. Since the 4.6.0-rc1 tag, we have merged a few small patches, but we don't have any known issues that might block the release. We discussed optee_ftpm briefly after that last release in January. The code quality leaves a bit to be desired, with many warnings, an inconsistent coding style, and possibly a few stubbed functions. How can we improve the status? Are there any other topics? Thanks, Jens

[PATCH v16 0/6] Introduction of a remoteproc tee to load signed firmware

by Arnaud Pouliquen

Main updates from version V15[1]: - Removed the rproc_ops:load_fw() operation introduced in the previous version. - Returned to managing the remoteproc firmware loading in rproc_tee_parse_fw to load and authenticate the firmware before getting the resource table. - Added spinlock and dev_link mechanisms in remoteproc TEE to better manage bind/unbind. More details are available in each patch commit message. [1] https://lore.kernel.org/linux-remoteproc/20241128084219.2159197-7-arnaud.po… Tested-on: commit 0a0ba9924445 ("Linux 6.14-rc7") Description of the feature: -------------------------- This series proposes the implementation of a remoteproc tee driver to communicate with a TEE trusted application responsible for authenticating and loading the remoteproc firmware image in an Arm secure context. 1) Principle: The remoteproc tee driver provides services to communicate with the OP-TEE trusted application running on the Trusted Execution Context (TEE). The trusted application in TEE manages the remote processor lifecycle: - authenticating and loading firmware images, - isolating and securing the remote processor memories, - supporting multi-firmware (e.g., TF-M + Zephyr on a Cortex-M33), - managing the start and stop of the firmware by the TEE. 2) Format of the signed image: Refer to: https://github.com/OP-TEE/optee_os/blob/master/ta/remoteproc/src/remoteproc… 3) OP-TEE trusted application API: Refer to: https://github.com/OP-TEE/optee_os/blob/master/ta/remoteproc/include/ta_rem… 4) OP-TEE signature script Refer to: https://github.com/OP-TEE/optee_os/blob/master/scripts/sign_rproc_fw.py Example of usage: sign_rproc_fw.py --in <fw1.elf> --in <fw2.elf> --out <signed_fw.sign> --key ${OP-TEE_PATH}/keys/default.pem 5) Impact on User space Application No sysfs impact. The user only needs to provide the signed firmware image instead of the ELF image. For more information about the implementation, a presentation is available here (note that the format of the signed image has evolved between the presentation and the integration in OP-TEE). https://resources.linaro.org/en/resource/6c5bGvZwUAjX56fvxthxds Arnaud Pouliquen (6): remoteproc: core: Introduce rproc_pa_to_va helper remoteproc: Add TEE support remoteproc: Introduce release_fw optional operation dt-bindings: remoteproc: Add compatibility for TEE support remoteproc: stm32: Create sub-functions to request shutdown and release remoteproc: stm32: Add support of an OP-TEE TA to load the firmware .../bindings/remoteproc/st,stm32-rproc.yaml | 58 +- drivers/remoteproc/Kconfig | 10 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/remoteproc_core.c | 52 ++ drivers/remoteproc/remoteproc_internal.h | 6 + drivers/remoteproc/remoteproc_tee.c | 619 ++++++++++++++++++ drivers/remoteproc/stm32_rproc.c | 139 +++- include/linux/remoteproc.h | 4 + include/linux/remoteproc_tee.h | 90 +++ 9 files changed, 935 insertions(+), 44 deletions(-) create mode 100644 drivers/remoteproc/remoteproc_tee.c create mode 100644 include/linux/remoteproc_tee.h base-commit: 0a0ba99244455fea8706c4a53f5f66a45d87905d -- 2.25.1

One case is the following example export MODULE=libckteec.so.0 while true ; do pkcs11-tool --module $MODULE --init-token --label "$TOKEN" --so-pin "$SOPIN" ; pkcs11-tool --module $MODULE --init-pin --so-pin "$SOPIN" --pin "$PIN" ; done Normally this runs fine. I tested this up to 40 hours without any issue. The moment I press Ctrl+C the linux kernel often crashes (ca. 20% chance). This can be reproduced easily (in less than 1 minute). It looks like always syscall_storage_obj_open is part of the execution path, often followed by a panic (which I assume is ok, if the underlining process dies) I believe the OPTEE RAM and SHM are correctly passed to the kernel [ 0.000000] OF: reserved mem: 0x0000000056000000..0x0000000057bfffff (28672 KiB) nomap non-reusable optee_core@56000000 [ 0.000000] OF: reserved mem: 0x0000000057c00000..0x0000000057ffffff (4096 KiB) nomap non-reusable optee_shm@57c00000 The kernel/OP-TEE logs are added below.

Preparing for OP-TEE 4.6.0

by Jens Wiklander

[BCC all OP-TEE maintainers] Hi OP-TEE maintainers & contributors, OP-TEE version 4.6.0 is scheduled to be released on 2025-04-25. 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/7359. We will create the release candidate tag 4.6.0-rc1 this Friday, allowing for a two-week testing period before the planned release. You can find more information related to releases here: https://optee.readthedocs.io/en/latest/general/releases.html Thanks, Jens
