2015-08-19crypto: cmac - allow usage in FIPS modeStephan Mueller1-0/+2
CMAC is an approved cipher in FIPS 140-2. The patch allows the use of CMAC with TDES and AES in FIPS mode. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-19crypto: sahara - Use dmam_alloc_coherentVaishali Thakkar1-37/+9
This patch moves the data allocated using dma_alloc_coherent to the corresponding managed interface. To be compatible with the change, various gotos are replaced with direct returns and unneeded labels are dropped.

2015-08-18crypto: caam - add support for LS1021AHoria Geant?4-10/+29
LS1021A is a QorIQ SoC having little endian CAAM. There are a few differences b/w QorIQ and i.MX from CAAM perspective: 1. i.MX platforms are somewhat special wrt. 64-bit registers: -big endian format at 64-bit level: MSW at address+0 and LSW at address+4 -little endian format at 32-bit level (within MSW and LSW) and thus need special handling. 2. No CCM (clock controller module) for QorIQ. No CAAM clocks to enable / disable. A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate CAAM is little endian (*). It is hidden from the user (to avoid misconfiguration); when adding support for a new platform with LE CAAM, either the Kconfig needs to be updated or the corresponding defconfig needs to indicate that CAAM is LE. (*) Using a DT property to provide CAAM endianness would not allow for the ifdeffery. In order to keep changes to a minimum, the following changes are postponed: -endianness fix of the last word in the S/G (rsvd2, bpid, offset), fields are always 0 anyway; -S/G format fix for i.MX7 (yes, i.MX7 support was not added yet, but still...)

2015-08-18crypto: vmx - Fixing GHASH Key issue on little endianLeonidas Da Silva Barbosa1-0/+6
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 <leosilva@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-08-17crypto: nx - Add forward declaration for struct crypto_aeadHerbert Xu1-0/+2

2015-08-10crypto: talitos - Prevent panic in probe error pathAaron Sierra2-2/+12
The probe error path for this driver, for all intents and purposes, is the talitos_remove() function due to the common "goto err_out". Without this patch applied, talitos_remove() will panic under these two conditions: 1. If the RNG device hasn't been registered via talitos_register_rng() prior to entry into talitos_remove(), then the attempt to unregister the RNG "device" will cause a panic. 2. If the priv->chan array has not been allocated prior to entry into talitos_remove(), then the per-channel FIFO cleanup will panic because of the dereference of that NULL "array". Both of the above scenarios occur if talitos_probe_irq() fails. This patch resolves issue #1 by introducing a boolean to mask the hwrng_unregister() call in talitos_unregister_rng() if RNG device registration was unsuccessful. It resolves issue #2 by checking that priv->chan is not NULL in the per-channel FIFO cleanup for loop.
