crypto: vmx - Fixing opcode issue

2015-08-24T14:07:43+00:00

In build time vadduqm opcode is not being mapped correctly. Adding a new map in ppc-xlate to do this. Signed-off-by: Leonidas S Barbosa Signed-off-by: Herbert Xu

crypto: vmx - Fixing GHASH Key issue on little endian

2015-08-18T02:30:36+00:00

GHASH table algorithm is using a big endian key. In little endian machines key will be LE ordered. After a lxvd2x instruction key is loaded as it is, LE/BE order, in first case it'll generate a wrong table resulting in wrong hashes from the algorithm. Bug affects only LE machines. In order to fix it we do a swap for loaded key. Cc: stable@vger.kernel.org Signed-off-by: Leonidas S Barbosa Signed-off-by: Herbert Xu

crypto: vmx - Fixing AES-CTR counter bug

2015-08-18T02:30:35+00:00

AES-CTR is using a counter 8bytes-8bytes what miss match with kernel specs. In the previous code a vadduwm was done to increment counter. Replacing this for a vadduqm now considering both cases counter 8-8 bytes and full 16bytes. Cc: stable@vger.kernel.org Signed-off-by: Leonidas S Barbosa Signed-off-by: Herbert Xu

crypto: vmx - Adding enable_kernel_vsx() to access VSX instructions

2015-07-14T06:56:48+00:00

vmx-crypto driver make use of some VSX instructions which are only available if VSX is enabled. Running in cases where VSX are not enabled vmx-crypto fails in a VSX exception. In order to fix this enable_kernel_vsx() was added to turn on VSX instructions for vmx-crypto. Signed-off-by: Leonidas S. Barbosa Signed-off-by: Herbert Xu

Pull crypto update from Herbert Xu: "Here is the crypto update for 4.2: API: - Convert RNG interface to new style. - New AEAD interface with one SG list for AD and plain/cipher text. All external AEAD users have been converted. - New asymmetric key interface (akcipher). Algorithms: - Chacha20, Poly1305 and RFC7539 support. - New RSA implementation. - Jitter RNG. - DRBG is now seeded with both /dev/random and Jitter RNG. If kernel pool isn't ready then DRBG will be reseeded when it is. - DRBG is now the default crypto API RNG, replacing krng. - 842 compression (previously part of powerpc nx driver). Drivers: - Accelerated SHA-512 for arm64. - New Marvell CESA driver that supports DMA and more algorithms. - Updated powerpc nx 842 support. - Added support for SEC1 hardware to talitos" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (292 commits) crypto: marvell/cesa - remove COMPILE_TEST dependency crypto: algif_aead - Temporarily disable all AEAD algorithms crypto: af_alg - Forbid the use internal algorithms crypto: echainiv - Only hold RNG during initialisation crypto: seqiv - Add compatibility support without RNG crypto: eseqiv - Offer normal cipher functionality without RNG crypto: chainiv - Offer normal cipher functionality without RNG crypto: user - Add CRYPTO_MSG_DELRNG crypto: user - Move cryptouser.h to uapi crypto: rng - Do not free default RNG when it becomes unused crypto: skcipher - Allow givencrypt to be NULL crypto: sahara - propagate the error on clk_disable_unprepare() failure crypto: rsa - fix invalid select for AKCIPHER crypto: picoxcell - Update to the current clk API crypto: nx - Check for bogus firmware properties crypto: marvell/cesa - add DT bindings documentation crypto: marvell/cesa - add support for Kirkwood and Dove SoCs crypto: marvell/cesa - add support for Orion SoCs crypto: marvell/cesa - add allhwsupport module parameter crypto: marvell/cesa - add support for all armada SoCs ...

crypto: vmx - Reindent to kernel style

2015-06-16T06:35:02+00:00

This patch reidents the vmx code-base to the kernel coding style. Signed-off-by: Herbert Xu

crypto: vmx - Remove duplicate PPC64 dependency

2015-06-16T06:35:01+00:00

The top-level CRYPTO_DEV_VMX option already depends on PPC64 so there is no need to depend on it again at CRYPTO_DEV_VMX_ENCRYPT. This patch also removes a redundant "default n". Signed-off-by: Herbert Xu

sched/preempt, powerpc: Disable preemption in enable_kernel_altivec() explicitly

2015-05-19T06:39:17+00:00

enable_kernel_altivec() has to be called with disabled preemption. Let's make this explicit, to prepare for pagefault_disable() not touching preemption anymore.
