Hi Abhishek, TSC representatives,
We're doing some changes when it comes to the Linaro TF TSC representatives.
- I'm stepping out (but I'm still around in Linaro).
- David Brown becomes the main Linaro TF TSC rep.
- Ruchika Gupta steps in as the backfill for David when he is unable to
attend.
Please update mailing-lists and meeting invitations etc accordingly.
Regards,
Joakim

Minutes:
-
Security Incident Reporting Review
-
Reference Joakims email thread
-
Joakim shared the background. Working to simplify. Walked thru a
sample incident process spreadsheet.
-
DB: How consistent in alerting additional Stakeholders?
-
Joakim: reference Phabricator page to answer the question.
-
Joakim: Process requires discipline. Shared checklist.
-
Each issue would have its own checklist.
-
KO: Looks good and provides the picture we need
-
KO: Why manual process?
-
JB: See checklist - must add dates
-
DanH: New tab for each checklist may be hard to sustain.
-
KO: Automation would be nice
-
AP: What is this solving?
-
KO: From Technical oversight, this provides a high-level view of
security robustness and responsiveness to issues. May be a
useful mgt tool
to understand security state and velocity is sufficient.
-
DB: With Zephyr, a checklist for each issue has caught things that
would have been missed, like publishing to MITRE.
-
DanH, AP: Agree checklists seem useful.
-
AP: Doesn’t include effort. What metric is needed?
-
DB: Need a start and an end, which doesn’t happen in this.
-
MT: Renesas uses Jira. Excel is tough - not scalable and can’t export
-
AP: What is the use of date for each transition?
-
DB: Checklists, and states in Jira. Jira is not trivial either and
must be tuned when changes are made. Clickup or Airtable might be good
choices. Scriptable is helpful. Not free solutions.
-
KO: Air table is $60 / month. Development/maintenance is the real
cost.
-
DanH: Corner cases are abundant and can skew statistics.
-
DB: Current sheet is a report, the data is the dates.
-
AP: Only stats that matter is when Opened and When closed. If
lock-on purpose, then can decide what data is needed.
-
DB: On zephyr, patches are done by others rather than the security
team, which makes it difficult. What happens when a 3rd party comes in?
-
DanH: Could be a case but hasn’t happened.
-
Agreed to table this and discuss again in a month
-
Phabricator Deprecation:
-
Noted raised and not discussed. Will discuss later
-
TF-M Release cadence change
-
Anton: From 4 to 6 months. Minimizes overhead associated with
releases
-
KO: Keeping the window open allows better synchronization.
-
Anton: Each project is different. Smaller windows have a better
chance to overlap.
-
EF: How aligns w/ MCUBoot?
-
Anton: No formal plan there, we pick it up asap.
-
EF: 2 versions in a time window. Make sure MCUBoot release is done 6
weeks before, for example, so can be merged in
-
Anton: This aligns with the purpose of this proposal. TF-A also has 6
months schedule.
-
AP: MBed TLS starting open tech Forum.
-
AP: ADAC repo - top-level repo now available. Expect a tech talk in the
future
-
AP: Roadmap discussions: None this month as it was covered last month,
plan to do every month. If can have lightning talks from Member reps on
how they’re using TF.org projects and are public. Still deciding if useful
and how to organize?
-
KO: A sense of how this is getting leveraged is the ultimate end
goal. A google project w/ BOM is being tracked for security issues that
impact other projects.
-
AP: Feel free to provide Abhishek feedback outside this forum
-
AP: Funding approval for Open CI. All aware
-
DonH: FYI includes reduction of Community Mgr to 0.3 to maintain a
healthy surplus. Also, the majority votes are in and it has passed.
-
Joakim: Can now compile OP TEE TA’s in Rust
<end>
Hi All,
Any agenda suggestions for this week's meeting?
Couple of potential topics :
* Security incident monitoring
* Phabricator deprecation
Thanks,
Abhishek
Hi All,
In case you missed a session of interest at Linaro Connect, the recorded
sessions and accompanying presentations are now posted on line
<https://connect.linaro.org/resources/lvc21f/lvc21f-212>.
I've attached a Session Resource List to this email as well that has been
created to quickly find sessions of interest based upon topics.
Best regards,
Don
Attendees:
Dan Handley (Arm, chair)
Joanna Farley (Arm)
Shebu Varghese Kuriakose (Arm)
Matteo Carlini (Arm)
Joakim Bech (Linaro)
David Brown (Linaro)
Don Harbin (Linaro)
Eric Finco (ST)
Lionel Debieve (ST)
KangKang Shen (Futurewei)
Michael Thomas (Renesas)
Julius Werner (Google)
Kevin Oerton (NXMLabs)
Andrey Butok (NXP)
Shebu presented Mbed TLS roadmap (attached)
KO: How will the Crypto Driver API be used.
SK: This is a back-end HAL interface for crypto-processors to plug in to. The front-end interface will always be the PSA Crypto API.
KO: Will this driver API help add support for certs that Mbed TLS doesn't support yet?
Shebu: No, the fron- end interface will always be via the Mbed TLS and PSA Crypto APIs. Adding new cert support would be a separate work item. Currently we're more focussed on new crypto algorithm support.
KO: For A-profile, is there a dependency on the Trusted Services (TS) project?
SVK: TS uses PSA Crypto, as does TF-A. There is some plumbing still to do with FF-A if you want to call PSA Crypto APIs from the normal world and route that through to TS or a Secure Element backend.
MT: When will there be a 3.x LTS branch?
SVK: Will consider the next LTS in 2022. The last 2.x branch will be an LTS. We don't have firm plans for a 3.x LTS branch yet.
MT: Even if you update Mbed TLS to use the PSA Crypto API, some partners will continue to use the legacy Mbed TLS crypto APIs (via Mbed TLS) since they will only use LTS branches. They will not move until there is an LTS that uses the PSA Crypto APIs.
DH: The strategy is to clean up the dependencies on the legacy crypto APIs through the 3.x series of releases. Eventually Mbed TLS will not have a dependency on the legacy APIs. Even then, backwards compatibility will be maintained in the legacy APIs. Support for the legacy APIs would not be removed until a (TBD) 4.0 release.
KO: Is there any overhead to using PSA Crypto API.
SVK: We haven't actually measured this.
DH: There will be a small overhead in the current implementation as these effectively wrap the legacy API implementations. There's no overhead due to the APIs themselves. Through the 3.x series of releases, the implementation will be inverted so that the legacy APIs will wrap the PSA Crypto API implementations. Then the overhead will be in the legacy implementation instead.
Matteo presented the TF-A roadmap: https://developer.trustedfirmware.org/w/tf_a/roadmap/
EF: What is firmware transparency? Is it a device side or server side technology?
MC: It's related to firmware attestation, which is about collecting firmware measurements and providing them to a relying party in the form of an attestation token.
DH: Actually, it’s a bit orthogonal to attestation. Attestation is about providing evidence to a (possibly remote) relying party in order enable functionality (e.g. provisioning of secrets).
DH: Firmware transparency is about making that evidence (in the form of certificates) available to anyone in a verifiable data store, so they can trust the firmware on a device is what it says it is
JB: So it's similar to TPM?
DH: Hmm, not exactly but the measurements may be stored in a TPM on the device.
DH: The project we’re interested in here is Google Trillian: https://opensource.google/projects/trillian
DH: This is really a server side technology but there may be some alignment activities to do on the device side
EF: What is the 32-bit support about in the roadmap?
SVK: This is related to Trusted Services (TS). It's about running legacy 32-bit TAs within TS, which is extra work
MC: Phabricator page for this: https://developer.trustedfirmware.org/w/tf_a/roadmap/
MC: Plan is to create a common landing page with Don for all roadmaps
AOB:
DH: Someone in Arm pointed out that the tagline on the tf.org website is not strictly accurate:
"OPEN SOURCE SECURE WORLD SOFTWARE"
DH: Some of the software does not necessarily reside in the secure world (e.g. Mbed TLS, Trusted Services, Future CCA support)
DH: Proposal is to just remove the word "World".
JK: Makes sense. I thought that too.
(No-one disagreed)
SVK: There's another reference on that page too.
DH: Yes, we may need to remove this in several places on the website.
ACTION: Dan to work with Don on changing "secure world" to "secure" on the website
JB: Board wanted more visibility into the security process, e.g. how fast are we to respond, what issues are in flight, etc...
DH: OK, as long as this isn't leaking security critical info to people who are not necessarily part of the security teams.
JB: Yes, of course. This is just about seeing how well the process is working, not the issues themselves
DH: My other concern is not putting too much extra process on the security teams.
JB: I have an action to propose something that is workable here.
DonH: Would like more of the tech people on the teams to propose topics at future conferences, e.g. the OSFC
DH: Arm folk have quite a few presentations at last week's LVC but perhaps not OSFC.
DonH: Yes, I was looking for more than just Arm people.
Regards
Dan.

Abhishek, all
referring to the minutes of our July meeting - see point highlighted in yellow below, TF-A was foreseen as the focus topic of the next TSC meeting. It was expected to take place in August but the August meeting has been cancelled so is TF-A slot postponed accordingly meaning is it the main topic of this week TSC ?
Regards,
Eric

§ Don: Action to Board on TSC needs?
· Shebu: Have TSC reps joined the board to share?
· AP: Will come up w/ questions posed to the board over the next month. September may be the appropriate time to have Board attendance. In TSC, can then formulate and make it more specific.
ACTION: AP come up with a list of topics/questions for the September joint TSC/Board meeting.
