Re: [TF-M] Regression observed in PSA Crypto after Mbed TLS upgrade to 2.25

by David Hu

Hi Alexander, Thanks for reporting this issue. Can I ask for more details of the failures? * What's the build configuration on PSoC 64 with PSA Arch test? * What's the version of TF-M? Have you tried the latest one in master branch? * What's the version of PSA Arch test? * Can you share more log of the failure test case? Thanks.

As far as we can tell, there is nothing else to be done associated with the 2.25 upgrade, i.e. the build automatically pulls 2.25 down, and there are no corresponding commits to psa-arch-tests to support the upgrade or any other changes necessary.

Re: [TF-M] Armclang linker alignement question

by Kevin Peng

Hi Michel, Quote from the armlink user guide: ALIGN on an execution region causes both the load address and execution address to be aligned. This can result in padding being added to the ELF file. To align only the execution address, use the AlignExpr expression on the base address. So I guess the alignment on execution regions (TFM_UNPRIV_CODE) overrides the alignment of the Load Region. And the fix is easy - as the user guide suggests - use AlignExpr In you case, could you try: +0 ALIGN 0x2000 -> AlignExpr(+0, 0x2000) Best Regards, Kevin From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Michel JAOUEN via TF-M Sent: Tuesday, March 16, 2021 10:33 PM To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Armclang linker alignement question Hello, This question is relative to linker script with Compiler armclang 'V6.14' (For the other toolchain IAR , GNUARM ,it works ) I need to place code aligned to flash PAGE SIZE (0x2000 or 8192) to be able to set hardware protection.

Re: [TF-M] Static analysic checking & reporting - inquiry about interest

by Karl Zhang

Hi Ioannis, Thanks for the suggestions. There are already a lot of info from Anton and Leonardo, I would like to clarify from: * The static check is applied to the CI per-patch job, it will feedback to the Gerrit review of each patch, this has been enabled per the recent mail, attached. * Coverity scan daily, and upload the result, https://scan.coverity.com/projects/trusted-firmware-m-35b064f0-65c2-4afb-9b… BR Karl From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org<mailto:tf-m-bounces@lists.trustedfirmware.org>> On Behalf Of Leonardo Sandoval via TF-M Sent: 2021年3月17日 23:15 To: Anton Komlev <Anton.Komlev(a)arm.com<mailto:Anton.Komlev@arm.com>> Cc: nd <nd(a)arm.com<mailto:nd@arm.com>>; tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> Subject: Re: [TF-M] Static analysic checking & reporting - inquiry about interest Hi Anton & Ioannis, Karl's presentation goes in detail but I just want to highlight that TF-M (and also TF-A) are two type of static checks: [1] Project related static checks & cppcheck executed per-patch [2] Coverity scan, executed daily For 1, other project-related static checks can be included.

To the best of my knowledge, this is not available today. In short, a simple process would involve maintaining and running static analysis checking (e.g. using Coverity or any other licensed tool) in nightly/weekly/etc. CI runs, reporting the found issues in the Project, triaging them, and tracking the progress of fixing the issues that are identified as real bugs. Has this topic been raised already in the Project? If not, is this something the project members would consider adding as part of the TF-M Project QA/release process? Thanks!
