Hi, We are refining the IRQ logic, and every time the new update pushed it needs to make the IRQ enabled test pass - as library model IRQ code is there, it needs efforts to create workarounds ensure the test pass every time. Check if someone is using the library mode IRQ handling (Check if you need the library model 'tfm_secure_irq_handlers.inc' or 'TFM_SVC_DEPRIV_REQ' is a quick path). If there are no users are using this logic we would disable this feature for a while till the IRQ logic get updated, this would save us much effort to maintain the legacy logic. This means if someone set 'TFM_IRQ_TEST' as ON the build system still ignore it. This action would happen after 1.3.0, we mention it now to give enough preparation for this. I would send another follow-up mail for chasing after the release. Please help to provide your feedback, thank you very much! /Ken

Re: [TF-M] Security vulnerability notice - SVC handler fetches incorrect caller stack pointer under specific cases.

by Kumar Gala

Agreed, I think it's a great thing for the SC to take up and make a policy on. Will add 2 cents: * Being a security focused project, I think its import that at least there is a patch release for the most recent officially released version, regardless of when the next release of TFM might be released. * Maybe looking at what policy a project like mbedtls has as a starting point. - k > On Mar 5, 2021, at 12:34 PM, Anton Komlev via TF-M <tf-m(a)lists.trustedfirmware.org> wrote: > > Hi Kumar, All, > > Thanks for bringing this topic up. > At the moment there is no plan for issuing the release v1.2.1 because of lack of policy for such hot fix releases.

Re: [TF-M] Security vulnerability notice - SVC handler fetches incorrect caller stack pointer under specific cases.

by Anton Komlev

Hi Kumar, All, Thanks for bringing this topic up. At the moment there is no plan for issuing the release v1.2.1 because of lack of policy for such hot fix releases. The release policy upgrade proposal shall be reviewed and agreed in the Steering Committee with the main questions: 1. What is the hot fix baseline? 2. What is the testing scope of the fix? 3. On which platform(s) the fix shall be tested? The policy is under discussion and the community input is welcome. Please share your thoughts on the topic. The release v1.3.0 is expected by end of March-beginning of April, which will include the fix.
