Pull crypto fixes from Herbert Xu: "This push fixes a memory corruption issue in caam, as well as reverting the new optimised crct10dif implementation as it breaks boot on initrd systems. Hopefully crct10dif will be reinstated once the supporting code is added so that it doesn't break boot" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: Revert "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" crypto: caam - Fixed the memory out of bound overwrite issue

When kernel is compiled with CONFIG_SLUB_DEBUG=y and CRYPTO_MANAGER_DISABLE_TESTS=n, during kernel bootup, the kernel reports error given below. The root cause is that in function hash_digest_key(), for allocating descriptor, insufficient memory was being allocated. The required number of descriptor words apart from input and output pointers are 8 (instead of 6). ============================================================================= BUG dma-kmalloc-32 (Not tainted): Redzone overwritten ----------------------------------------------------------------------------- Disabling lock debugging due to kernel taint INFO: 0xdec5dec0-0xdec5dec3.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (101 commits) crypto: ux500: use dmaengine_submit API crypto: ux500: use dmaengine_prep_slave_sg API crypto: ux500: use dmaengine_device_control API crypto: ux500/crypt: add missing __iomem qualifiers crypto: ux500/hash: add missing static qualifiers crypto: ux500/hash: use readl on iomem addresses dmaengine: ste_dma40: Declare memcpy config as static ARM: ux500: Remove mop500_snowball_ethernet_clock_enable() ARM: ux500: Correct the EN_3v3 regulator's on/off GPIO ARM: ux500: Provide a AB8500 GPIO Device Tree node gpio: rcar: fix gpio_rcar_of_table gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections gpio-rcar: Reference core gpio documentation in the DT bindings clk: exynos5250: Add enum entries for divider clock of i2s1 and i2s2 ARM: dts: Update Samsung I2S documentation ARM: dts: add clock provider information for i2s controllers in Exynos5250 ARM: dts: add Exynos audio subsystem clock controller node clk: samsung: register audio subsystem clocks using common clock framework ARM: dts: use #include for all device trees for Samsung pinctrl: s3c24xx: use correct header for chained_irq functions ...

2013-06-05crypto: omap-aes - Don't idle/start AES device between Encrypt operationsJoel A Fernandes1-10/+19
Calling runtime PM API for every block causes serious perf hit to crypto operations that are done on a long buffer. As crypto is performed on a page boundary, encrypting large buffers can cause a series of crypto operations divided by page. The runtime PM API is also called those many times. We call runtime_pm_get_sync only at beginning on the session (cra_init) and runtime_pm_put at the end. This result in upto a 50% speedup as below. This doesn't make the driver to keep the system awake as runtime get/put is only called during a crypto session which completes usually quickly.

2013-05-28crypto: dcp - Added support for Freescale's DCP co-processorTobias Rauter3-0/+936
This patch enables the DCP crypto functionality on imx28. Currently, only aes-128-cbc is supported. Moreover, the dcpboot misc-device, which is used by Freescale's SDK tools and uses a non-software-readable OTP-key, is added. Changes of v2: - ring buffer for hardware-descriptors - use of ablkcipher walk - OTP key encryption/decryption via misc-device (compatible to Freescale-SDK) - overall cleanup The DCP is also capable of sha1/sha256 but I won't be able to add that anytime soon. Tested with built-in runtime-self-test, tcrypt and openssl via cryptodev 1.6 on imx28-evk and a custom built imx28-board.

2013-05-24drivers/crypto/nx: Fixes for multiple races and issuesKent Yoder6-38/+19
Fixes a race on driver init with registering algorithms where the driver status flag wasn't being set before self testing started. Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.
