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

EL3 SPMC shmem datastore sizing for FFA_MEM_RETRIEVE_REQ snapshot

by Daniel Boulby

Hi all, I am sending this note to get feedback from platform maintainers on an EL3 SPMC change in my current series (https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/50778/). The patch updates spmc_ffa_mem_retrieve_req() to take a snapshot of the caller's FFA_MEM_RETRIEVE_REQ descriptor into the EL3 SPMC shmem datastore before validation and response handling. The intent is to avoid repeatedly reading mutable fields from the caller-owned TX buffer while the request is being processed. In other words, once the request enters EL3 SPMC, we operate on a stable local copy rather than on memory that remains under the caller's control. The EL3 SPMC datastore is already used to cache shared memory transaction descriptors. With this change, it is also used to hold a temporary copy of the retrieve request. That means datastore sizing becomes more important, since a valid larger retrieve request may now fail if the backing datastore is too small. The datastore sizes are defined in platform_def.h (https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/… for the fvp platform) and while looking through the existing platform definitions, I noticed that datastore sizes vary quite a lot. For example, some platforms provide a relatively large backing store, while others define much smaller regions. In particular, rdn2 currently defines only a 1024-byte datastore. My concern is that for such platforms, larger memory-share / retrieve flows could fail simply because the datastore is too small to hold the request snapshot. Before I proceed further, I wanted to ask platform maintainers: 1. Is there any platform-specific reason for these reduced datastore sizes? 2. If not, would maintainers be happy for these datastore sizes to be increased so they can accommodate larger valid transactions? In short, I want to confirm whether the smaller datastore definitions are deliberate platform constraints, or whether they should be treated as undersized defaults that now need revisiting. Feedback from maintainers would be very helpful before I post the next revision. Kind Regards, Daniel Boulby

Firmware-A v2.12 release code freeze notification

by Govindraj Raja

Hi All, The next release of the Firmware-A bundle of projects tagged v2.12 has an expected code freeze date of Nov, 8th 2024. Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…). Closing out the release takes around 6-10 working days after the code freeze. v2.12 release preparation tasks start from now. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.: -For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). -For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 labels in the middle of the patch stack). -Carefully analyze results and fix the change if required, before launching new jobs on the same change. -If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. -- Thanks, Govindraj R
