This is a note to let you know that I've just added the patch titled crypto: arm64/sha - add missing module aliases to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-arm64-sha-add-missing-module-aliases.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 0df07d8117c3576f1603b05b84089742a118d10a Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel <ardb@xxxxxxxxxx> Date: Thu, 14 Jan 2021 19:10:10 +0100 Subject: crypto: arm64/sha - add missing module aliases From: Ard Biesheuvel <ardb@xxxxxxxxxx> commit 0df07d8117c3576f1603b05b84089742a118d10a upstream. The accelerated, instruction based implementations of SHA1, SHA2 and SHA3 are autoloaded based on CPU capabilities, given that the code is modest in size, and widely used, which means that resolving the algo name, loading all compatible modules and picking the one with the highest priority is taken to be suboptimal. However, if these algorithms are requested before this CPU feature based matching and autoloading occurs, these modules are not even considered, and we end up with suboptimal performance. So add the missing module aliases for the various SHA implementations.
