2016-03-11crypto: qat - Change the definition of icp_qat_uof_regtypePingchao Yang1-21/+21
The definition of icp_qat_uof_regtype should be coherent with the definition in firmware compiler. Signed-off-by: Yang Pingchao <pingchao.yang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-03-11hwrng: exynos - use __maybe_unused to hide pm functionsArnd Bergmann1-6/+4
The exynos random driver uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/char/hw_random/exynos-rng.c:166:12: error: 'exynos_rng_suspend' defined but not used [-Werror=unused-function] drivers/char/hw_random/exynos-rng.c:171:12: error: 'exynos_rng_resume' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition.

2016-03-11crypto: ccp - Add abstraction for device-specific callsGary R Hook7-667/+710
Support for different generations of the coprocessor requires that an abstraction layer be implemented for interacting with the hardware. This patch splits out version-specific functions to a separate file and populates the version structure (acting as a driver) with function pointers.

2016-03-11crypto: ccp - CCP versioning supportGary R Hook7-5/+115
Future hardware may introduce new algorithms wherein the driver will need to manage resources for different versions of the cryptographic coprocessor. This precursor patch determines the version of the available device, and marks and registers algorithms accordingly. A structure is added which manages the version-specific data.

Enable management of >1 CCPs in a system. Each device will get a unique identifier, as well as uniquely named resources. Treat each CCP as an orthogonal unit and register resources individually.

2016-03-11crypto: ccp - Remove check for x86 family and modelGary R Hook1-36/+11
Each x86 SoC will make use of a unique PCI ID for the CCP device so it is not necessary to check for the CPU family and model. Signed-off-by: Gary R Hook <gary.hook@amd.com> Acked-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-02-28crypto: ccp - memset request context to zero during importTom Lendacky2-0/+2
Since a crypto_ahash_import() can be called against a request context that has not had a crypto_ahash_init() performed, the request context needs to be cleared to insure there is no random data present. If not, the random data can result in a kernel oops during crypto_ahash_update().

2016-02-28lib/mpi: use "static inline" instead of "extern inline"Arnd Bergmann2-5/+5
When we use CONFIG_PROFILE_ALL_BRANCHES, every 'if()' introduces a static variable, but that is not allowed in 'extern inline' functions: mpi-inline.h:116:204: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static mpi-inline.h:113:184: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static mpi-inline.h:70:184: warning: '______f' is static but declared in inline function 'mpihelp_add' which is not static mpi-inline.h:56:204: warning: '______f' is static but declared in inline function 'mpihelp_add_1' which is not static This changes the MPI code to use 'static inline' instead, to get rid of hundreds of warnings.

A wrapper around the umull assembly instruction might reuse the input register as an output, which is undefined on some ARM machines, as pointed out by this assembler warning: CC lib/mpi/generic_mpih-mul1.o /tmp/ccxJuxIy.s: Assembler messages: /tmp/ccxJuxIy.s:53: rdhi, rdlo and rm must all be different CC lib/mpi/generic_mpih-mul2.o /tmp/ccI0scAD.s: Assembler messages: /tmp/ccI0scAD.s:53: rdhi, rdlo and rm must all be different CC lib/mpi/generic_mpih-mul3.o /tmp/ccMvVQcp.s: Assembler messages: /tmp/ccMvVQcp.s:53: rdhi, rdlo and rm must all be different This changes the constraints to force different registers to be used as output.

2016-02-28lib/mpi: Endianness fixMichal Marek1-18/+21
The limbs are integers in the host endianness, so we can't simply iterate over the individual bytes. The current code happens to work on little-endian, because the order of the limbs in the MPI array is the same as the order of the bytes in each limb, but it breaks on big-endian.

2016-02-17crypto: xts - consolidate sanity check for keysStephan Mueller13-53/+71
The patch centralizes the XTS key check logic into the service function xts_check_key which is invoked from the different XTS implementations. With this, the XTS implementations in ARM, ARM64, PPC and S390 have now a sanity check for the XTS keys similar to the other arches. In addition, this service function received a check to ensure that the key != the tweak key which is mandated by FIPS 140-2 IG A.9. As the check is not present in the standards defining XTS, it is only enforced in FIPS mode of the kernel.
