Function parameter should not be modified.

by Nithin G

Hello, In the file common/bl_common.c and other related files, there are instances where function parameters are being modified. This leads to violations when running the Coverity MISRA-C analysis for the ZynqMP platform. To address this issue a new variable is declared and used to store the value from the argument in the code. Is it possible to fix by taking a new variable? Please provide your suggestions. Regards, Nithin G

The condition clause of the for loop does not use the loop counter variable.

by Nithin G

Hello, In the file lib/xlat_tables/xlat_tables_common.c and other related files, the condition clause of the for loop does not use the loop counter variable "mm". This leads to violations when running the Coverity MISRA-C analysis for the ZynqMP platform. Addressing this issue added mm as part of loop counter and this belongs to core translational table logic and other violations also related to this. Is it possible to address this issue? Please provide your suggestions. Regards, Nithin G

Function bl31_lib_init() has external linkage but is only used in one translation unit.

by Nithin G

Hello, In the file bl31/bl31_main.c, there is a function named bl31_lib_init with its definition. Simultaneously, the declaration of this function is included in include/bl31/bl31.h since the function bl31_lib_init used only in one translational unit. leading to a violation when running the Coverity MISRA-C analysis for the ZynqMP. Addressing this issue need to remove the declaration of the function from the bl31.h file and making its definition static. To maintain visibility, included a static declaration in the bl31_main.c file. However, it will may impact in future modifications due to the removal of the declaration in bl31.h. Please provide your suggestions. Regards, Nithin

Experimental rust-spmc project release

by Imre Kis

Dear All, We would like to announce that we have published an experimental project called rust-spmc which is a S-EL1 FF-A Secure Partition Manager Core implementation in Rust. We started this as a free time project and now we had the opportunity to publish it on trustedfirmware.org. In its current state it has a partial implementation of the FF-A protocol, and it is able to run the secure partitions of Trusted Services with all tests passing on Arm FVP. It also provides the required compartmentalization between the S-EL0 secure partitions. Please note that the project is experimental (i.e. PoC, not suitable for production) and it is currently not scheduled by Arm for further development. The Rust language is an ideal language for implementing firmware components given its lack of undefined behavior and its memory safety guarantees. Our goal was to demonstrate the capabilities of language in a security critical firmware environment and to gather feedback from partners which could open up the possibility of further development of the project. The repository is available here: https://git.trustedfirmware.org/rust-spmc/rust-spmc.git/ We also prepared a readme with instructions for testing the project: https://git.trustedfirmware.org/rust-spmc/rust-spmc.git/about/ Please reach out to us if you are interested in the project or if you have any questions. Regards, Bálint Dobszay & Imre Kis
