This is a note to let you know that I've just added the patch titled crypto: x86/aria - fix crash with CFI enabled to the 6.1-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-x86-aria-fix-crash-with-cfi-enabled.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1ba84c31ca8f08cc84ad927fda3a8f19587b22e9 Author: Eric Biggers <ebiggers@xxxxxxxxxx> Date: Fri Nov 18 11:44:11 2022 -0800 crypto: x86/aria - fix crash with CFI enabled [ Upstream commit c67b553a4f4a8bd921e4c9ceae00e111be09c488 ] aria_aesni_avx_encrypt_16way(), aria_aesni_avx_decrypt_16way(), aria_aesni_avx_ctr_crypt_16way(), aria_aesni_avx_gfni_encrypt_16way(), aria_aesni_avx_gfni_decrypt_16way(), and aria_aesni_avx_gfni_ctr_crypt_16way() are called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause their type hashes to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure.
