Check early whether device registers can be accessed. Some BIOSes have a broken security policy that prevents access to the device registers, and return values from ioread() can be misinterpreted. If a read of a feature register returns a -1, we may not be able to access any device register, so report the problem and suggestion, and return. For the PSP, the feature register is checked. For the CCP, the queue register is checked. Signed-off-by:

If an AMD BIOS makes zero CCP queues available to the driver, the device is unavailable and therefore can't be activated. When this happens, report the status but don't report a (non-existent) failure. The CCP will be unactivated. Signed-off-by:

SEV INIT command loads the SEV related persistent data from NVS and initializes the platform context. The firmware validates the persistent state. If validation fails, the firmware will reset the persisent state and return an integrity check failure status. At this point, a subsequent INIT command should succeed, so retry the command. The INIT command retry is only done during driver initialization. Additional enums along with SEV_RET_SECURE_DATA_INVALID are added to sev_ret_code to maintain continuity and relevance of enum values. Signed-off-by:

Add the logic to deal with input sizes that are not a round multiple of the AES block size, as described by the XTS spec.

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.

Set the ivsize for the "ecb-ppc-spe" algorithm to 0, since ECB mode doesn't take an IV. This fixes a failure in the extra crypto self-tests: alg: skcipher: ivsize for ecb-ppc-spe (16) doesn't match generic impl (0) Signed-off-by:

The PowerPC SPE implementations of AES modes only disable preemption during the actual encryption/decryption, not during the scatterwalk functions. It's therefore unnecessary to request an atomic scatterwalk. So don't do so. Signed-off-by:

In order to speed up aegis128 processing even more, duplicate the init() and final() routines as SIMD versions in their entirety. This results in a 2x speedup on ARM Cortex-A57 for ~1500 byte packets (using AES instructions). Signed-off-by:
