[Feedback Requested] Reverting setting SCR_EL3.EA in EL3

by Okash Khawaja

Hi, Commit 327f4bb0cf20 ("fix(el3_runtime): allow SErrors when executing in EL3")[1], seems disruptive for LTS branch at this stage. Therefore we, the LTS maintainers, propose to revert it in the lts-v2.8 branch. The reason is that if a misbehaving binary is running in a lower EL, e.g. one which has external aborts masked while executing instructions which cause SErrors, then it's possible for those SErrors to be received by EL3 even if they weren't caused by it. This is a change in the contract between EL3 and lower ELs, that existed at the time when TF-A v2.8 was released. LTS 2.8 is based on TF-A 2.8. Revert patch, which is not yet submitted, can be found here[2]. If you have any comments or objections please share before the end of Friday 24th February Pacific Time. We'll merge it after that. Thanks, Okash [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/18953 [2] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/19094

[LTS v2.8.0] RC0 tag has been created

by Varun Wadekar

Hello, As announced in the last Tech forum, the code freeze date for the LTS branch was Feb 3, 2023. We have now merged all the patches published on the wiki [1]. The branch is still locked, and all the CI test runs have now been completed. We are trying to root cause one test failure, though. The RC0 tag was created today, and we request platform owners test the branch [2] on their downstream platforms if they wish. We are still on track to release on Feb 10 and will publish more updates shortly. Thanks.
