From 7f725f41f62750832817047e44892ce92d65e6aa Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 14 Oct 2019 19:45:17 -0700 Subject: crypto: powerpc - convert SPE AES algorithms to skcipher API Convert the glue code for the PowerPC SPE implementations of AES-ECB, AES-CBC, AES-CTR, and AES-XTS from the deprecated "blkcipher" API to the "skcipher" API. This is needed in order for the blkcipher API to be removed. Tested with: export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make mpc85xx_defconfig cat >> .config << EOF # CONFIG_MODULES is not set # CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set CONFIG_DEBUG_KERNEL=y CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y CONFIG_CRYPTO_AES=y CONFIG_CRYPTO_CBC=y CONFIG_CRYPTO_CTR=y CONFIG_CRYPTO_ECB=y CONFIG_CRYPTO_XTS=y CONFIG_CRYPTO_AES_PPC_SPE=y EOF make olddefconfig make -j32 qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \ -kernel arch/powerpc/boot/zImage \ -append cryptomgr.fuzz_iterations=1000 Note that xts-ppc-spe still fails the comparison tests due to the lack of ciphertext stealing support. This is not addressed by this patch. This patch also cleans up the code by making ->encrypt() and ->decrypt() call a common function for each of ECB, CBC, and XTS, and by using a clearer way to compute the length to process at each step.
