[PATCH v7 0/7] arm_ffa, KVM: Fix FF-A emad offset calculations

by Sebastian Ene

Hi all, This series fixes the Endpoint Memory Access Descriptor (EMAD) offset calculations and adds the necessary bounds checks for both the core FF-A driver and the pKVM hypervisor. Prior to FF-A version 1.1, the memory region header didn't specify an explicit offset for the EMADs, leading to the assumption that they immediately follow the header. However, from v1.1 onwards, the specification dictates using the ep_mem_offset` field to determine the start of the memory access array. The patches in this series address this by: 1. Updating the core `arm_ffa` firmware driver to correctly calculate the descriptor offset using `ep_mem_offset` rather than defaulting to `sizeof(struct ffa_mem_region)`. It also introduces bounds checking against `max_fragsize`. 2. Enhancing the pKVM hypervisor validation logic to no longer strictly enforce that the descriptor strictly follows the header, aligning it with the driver behavior and the FF-A specification, while also ensuring the offset falls within the mailbox buffer bounds. While addressing these bugs, Sashiko uncovered other issues that were fixed in the same series. All the patches aside from the first one in optee are urgent fixes as they either impact the hypervisor security or kernel stability. Changelog ######### v6->v7: - taking the patches from Mostafa and sending a new version with the collected tags - Added overflow checks when doing `ep_offset + emad_size` in the arm ff-a driver - Move the length check before the ffa_mem_reclaim - fix compatibility break with ff-a version 1.0 reported by Sashiko - add one more patch to fix an issue with the FFA_VERSION call that can lead to leaking pKVM stack un-initialized data to a host when -ftrivial-auto-var-init=zero is not used. v5->v6: - Add fixes tag - Small clean up make variable declaration reverse christmas tree. v4->v5: - Collect Sudeep Rbs - Add extra patch to check base address alignment. - Remove WARN_ONs in KVM code - Use ffa_emad_size_get() instead of hardcoded size in KVM code. v3 -> v4: - Address review comments and fix Sashiko bugs v2 -> v3: - Fixed typo in nvhe/ffa.c (missing sizeof) v1 -> v2: - For pKVM, removed the strict placement enforcement for `ep_mem_offset` as it is not compliant with the spec, and avoids making assumptions about the driver's memory layout.

[PATCH v1] tee: qcomtee: Drop unused assignment of platform_device_id driver data

by Uwe Kleine-König (The Capable Hub)

The driver explicitly sets the .driver_data member of struct platform_device_id to zero without relying on that value. Drop this unused assignment. While touching this array unify spacing and usage of commas and use a named initializer for .name for improved readability. Signed-off-by: Uwe Kleine-König (The Capable Hub) <u.kleine-koenig(a)baylibre.com> --- Hello, while this is a cleanup that can stand on its own, it is also a preparation for a change to struct platform_device_id that requires that .driver_data isn't assigned by a list initializer.

Proposal to unify tf.org vulnerability referencing in NVD

by Sandrine Bailleux

Hi everyone, I am sending this email to all tf.org project mailing lists to ensure all maintainers are aware and on board regarding this matter. If you have any concerns or questions, please reply on tf.org Discord #general channel, where I'll create a thread, as I think it will be much easier than dealing with cross-mailing lists emails. Background When a security vulnerability is discovered in one of the trustedfirmware.org projects, it is common to request a "Common Vulnerabilities and Exposures" (CVE) number. This number uniquely references the issue, which can then be searched in the vulnerability databases. One of these databases is NIST's "National Vulnerability Database" (NVD): https://nvd.nist.gov<https://nvd.nist.gov/vuln/detail/CVE-2023-51712> Entering a specific CVE number in NVD search engine will allow you to easily find the details of a specific issue, for example: https://nvd.nist.gov/vuln/detail/CVE-2023-51712 However, sometimes one is not looking for a specific CVE number but rather wants to list all known vulnerabilities affecting a particular project. For this, one can use the Common Platform Enumerations (CPE) search engine: https://nvd.nist.gov/products/cpe/search CPE is a structured naming scheme that includes information like the vendor name, the project name, the version / tag, and so on. See https://nvd.nist.gov/products/cpe for more details. So for example, https://nvd.nist.gov/vuln/detail/CVE-2023-51712 referenced above has the following CPE: cpe:2.3:o:arm:trusted_firmware-m:*:*:*:*:*:*:*:* This basically means * CPE version 2.3 is in use * 'o is the type of project, in this case it stands for Operating Systems (which is probably the closest match for low-level code like TF-M) * 'arm' is the vendor (that is wrong, see below) * 'trusted_firmware-m' is the project name, Problem statement It appears that CPEs used in NVD to reference vulnerabilities in tf.org projects differ a lot across projects. For some projects, there's even multiple of them. Sometimes the vendor is "arm", sometimes it's "linaro", or something else. Some of the TF-A and MbedTLS maintainers have initiated discussions with NVD to get this simplified and unified, but it would make sense to align other tf.org projects as well. Proposal CPE naming rules are that the vendor name should the parent organization of the project. Thus the proposal would be for all tf.org projects to use "trustedfirmware" as the vendor name in their CPE. For example: cpe:2.3:o:trustedfirmware:trusted_firmware-m:*:*:*:*:*:*:*:* cpe:2.3:a:trustedfirmware:mbed_tls:*:*:*:*:*:*:*:* We're only proposing to change the vendor name here ; each project is then free to choose how they want the project name or the type of software project they want to encode there. Thanks for reading, Best regards, Sandrine Afsa

OP-TEE Contributions Forum, monthly meeting May 26

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another OP-TEE contributors' monthly meeting. For time and connection details, see the calendar at https://www.trustedfirmware.org/meetings/ Regarding Kconfig support:https://github.com/OP-TEE/optee_os/pull/7714 It appears that the transition will take quite some time. We'll have a window when some variables have transitioned to be managed by Kconfig, but others remain managed by the makefiles. Do we care that variables passed on the command line may work differently, depending on whether they are managed by makefiles or Kconfig? Can something be done about it? Any other topics? Cheers, Jens

[PATCH v7 00/15] firmware: qcom: Add OP-TEE PAS service support

by Sumit Garg

From: Sumit Garg <sumit.garg(a)oss.qualcomm.com> Qcom platforms has the legacy of using non-standard SCM calls splintered over the various kernel drivers. These SCM calls aren't compliant with the standard SMC calling conventions which is a prerequisite to enable migration to the FF-A specifications from Arm. OP-TEE as an alternative trusted OS to Qualcomm TEE (QTEE) can't support these non-standard SCM calls. And even for newer architectures using S-EL2 with Hafnium support, QTEE won't be able to support SCM calls either with FF-A requirements coming in. And with both OP-TEE and QTEE drivers well integrated in the TEE subsystem, it makes further sense to reuse the TEE bus client drivers infrastructure. The added benefit of TEE bus infrastructure is that there is support for discoverable/enumerable services. With that client drivers don't have to manually invoke a special SCM call to know the service status. So enable the generic Peripheral Authentication Service (PAS) provided by the firmware. It acts as the common layer with different TZ backends plugged in whether it's an SCM implementation or a proper TEE bus based PAS service implementation. The TEE PAS service ABI is designed to be extensible with additional API as PTA_QCOM_PAS_CAPABILITIES. This allows to accommodate any future extensions of the PAS service needed while still maintaining backwards compatibility. Currently OP-TEE support is being added to provide the backend PAS service implementation which can be found as part of this PR [1]. This implementation has been tested on Kodiak/RB3Gen2 board with lemans EVK board being the next target. In addition to that WIN/IPQ targets planning to use OP-TEE will use this service too. Surely the backwards compatibility is maintained and tested for SCM backend. Note that kernel PAS service support while running in EL2 is at parity among OP-TEE vs QTEE. Especially the media (venus/iris) support depends on proper IOMMU support being worked out on the PAS client end. Patch summary: - Patch #1: adds Kodiak EL2 overlay since boot stack with TF-A/OP-TEE only allow UEFI and Linux to boot in EL2. - Patch #2: adds generic PAS service. - Patch #3: migrates SCM backend to generic PAS service. - Patch #4: adds TEE/OP-TEE backend for generic PAS service. - Patch #5-#13: migrates all client drivers to generic PAS service. - Patch #14: drops legacy PAS SCM exported APIs. The patch-set is based on qcom tree tip [2] and can be found in git tree here [3]. Merge strategy: It is expected due to APIs dependency, the entire patch-set to go via the Qcom tree. All other subsystem maintainers, it will be great if I can get acks for the corresponding subsystem patches.
