2019-10-26crypto: ccp - Verify access to device registers before initializingHook, Gary
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: Gary R Hook <gary.hook@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-10-26crypto: ccp - Change a message to reflect status instead of failureHook, Gary
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.

2019-10-26crypto: ccp - Retry SEV INIT command in case of integrity check failure.Ashish Kalra
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.

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.

2019-10-23crypto: inside-secure - Made locally used safexcel_pci_remove() staticPascal van Leeuwen
safexcel_pci_remove() is only used locally in the module and not exported, so added a static function specifier. This fixes a sparse issue reported by Ben Dooks.

2019-10-23hwrng: core - Fix use-after-free warning in hwrng_register()Laurent Vivier
Commit daae28debcb0 has moved add_early_randomness() out of the rng_mutex and tries to protect the reference of the new rng device by incrementing the reference counter. But in hwrng_register(), the function can be called with a new device that is not set as the current_rng device and the reference has not been initialized. This patch fixes the problem by not using the reference counter when the device is not the current one: the reference counter is only meaningful in the case of the current rng device and a device is not used if it is not the current one (except in hwrng_register()) The problem has been reported by Marek Szyprowski on ARM 32bit Exynos5420-based Chromebook Peach-Pit board: WARNING: CPU: 3 PID: 1 at lib/refcount.c:156 hwrng_register+0x13c/0x1b4 refcount_t: increment on 0; use-after-free.

2019-10-23crypto: nx - don't abuse blkcipher_desc to pass iv aroundEric Biggers
The NX crypto driver is using 'struct blkcipher_desc' to pass the IV around, even for AEADs (for which it creates the struct on the stack). This is not appropriate since this structure is part of the "blkcipher" API, which is deprecated and will be removed. Just pass around the IV directly instead.
