2017-03-09crypto: zip - Add ThunderX ZIP driver coreMahipal Challa1-0/+7
Add a driver for the ZIP engine found on Cavium ThunderX SOCs. The ZIP engine supports hardware accelerated compression and decompression. It includes 2 independent ZIP cores and supports: - DEFLATE compression and decompression (RFC 1951) - LZS compression and decompression (RFC 2395 and ANSI X3.241-1994) - ADLER32 and CRC32 checksums for ZLIB (RFC 1950) and GZIP (RFC 1952) The ZIP engine is presented as a PCI device. It supports DMA and scatter-gather. Signed-off-by: Mahipal Challa <Mahipal.Challa@cavium.com> Signed-off-by: Jan Glauber <jglauber@cavium.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2017-02-24s390/crypt: Add protected key AES moduleMartin Schwidefsky1-0/+1
This patch introduces a new in-kernel-crypto blockcipher called 'paes' which implements AES with protected keys. The paes blockcipher can be used similar to the aes blockcipher but uses secure key material to derive the working protected key and so offers an encryption implementation where never a clear key value is exposed in memory. The paes module is only available for the s390 platform providing a minimal hardware support of CPACF enabled with at least MSA level 3. Upon module initialization these requirements are checked. Includes additional contribution from Harald Freudenberger. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

This patch introcudes a new kernel module pkey which is providing protected key handling and management functions. The pkey API is available within the kernel for other s390 specific code to create and manage protected keys. Additionally the functions are exported to user space via IOCTL calls. The implementation makes extensive use of functions provided by the zcrypt device driver. For generating protected keys from secure keys there is also a CEX coprocessor card needed.

With the new authenc support, we get a harmless Kconfig warning: warning: (CRYPTO_DEV_ATMEL_AUTHENC) selects CRYPTO_DEV_ATMEL_SHA which has unmet direct dependencies (CRYPTO && CRYPTO_HW && ARCH_AT91) The problem is that each of the options has slightly different dependencies, although they all seem to want the same thing: allow building for real AT91 targets that actually have the hardware, and possibly for compile testing. This makes all four options consistent: instead of depending on a particular dmaengine implementation, we depend on the ARM platform, CONFIG_COMPILE_TEST as an alternative when that is turned off. This makes the 'select' statements work correctly.

2017-02-03crypto: atmel-authenc - add support to authenc(hmac(shaX), Y(aes)) modesCyrille Pitchen1-0/+12
This patchs allows to combine the AES and SHA hardware accelerators on some Atmel SoCs. Doing so, AES blocks are only written to/read from the AES hardware. Those blocks are also transferred from the AES to the SHA accelerator internally, without additionnal accesses to the system busses. Hence, the AES and SHA accelerators work in parallel to process all the data blocks, instead of serializing the process by (de)crypting those blocks first then authenticating them after like the generic crypto/authenc.c driver does. Of course, both the AES and SHA hardware accelerators need to be available before we can start to process the data blocks. Hence we use their crypto request queue to synchronize both drivers.

Building the mediatek driver on an older ARM architecture results in a harmless warning: warning: (ARCH_OMAP2PLUS_TYPICAL && CRYPTO_DEV_MEDIATEK) selects NEON which has unmet direct dependencies (VFPv3 && CPU_V7) We could add an explicit dependency on CPU_V7, but it seems nicer to open up the build to additional configurations. This replaces the ARM optimized algorithm selection with the normal one that all other drivers use, and that in turn lets us relax the dependency on ARM and drop a number of the unrelated 'select' statements. Obviously a real user would still select those other optimized drivers as a fallback, but as there is no strict dependency, we can leave that up to the user.

This patch introduces virtio-crypto driver for Linux Kernel. The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in the future. The virtio crypto device provides the following cryptoservices: CIPHER, MAC, HASH, and AEAD.

The Atmel at91 crypto driver unconditionally selects AT_HDMAC, which results in a Kconfig warning if that driver is not enabled: warning: (CRYPTO_DEV_ATMEL_AES) selects AT_HDMAC which has unmet direct dependencies (DMADEVICES && ARCH_AT91) The crypto driver itself does not actually have a dependency on a particular dma engine, other than this being the one that is used in at91. Removing the 'select' gets rid of the warning, but can cause the driver to be unusable if the HDMAC is not enabled at the same time. To work around that, this patch clarifies the runtime dependency to be 'AT_HDMAC || AT_XDMAC', but adds an alternative for COMPILE_TEST, which lets the driver get build on all systems. The ARCH_AT91 dependency is implied by AT_XDMAC || AT_HDMAC now and no longer needs to be listed separately.

The CESA IP supports CPU offload through a dedicated DMA engine (TDMA) which can control the crypto block. When you use this mode, all the required data (operation metadata and payload data) are transferred using DMA, and the results are retrieved through DMA when possible (hash results are not retrieved through DMA yet), thus reducing the involvement of the CPU and providing better performances in most cases (for small requests, the cost of DMA preparation might exceed the performance gain). Note that some CESA IPs do not embed this dedicated DMA, hence the activation of this feature on a per platform basis.

2015-06-19crypto: mv_cesa - use gen_pool to reserve the SRAM memory regionBoris BREZILLON1-0/+1
The mv_cesa driver currently expects the SRAM memory region to be passed as a platform device resource. This approach implies two drawbacks: - the DT representation is wrong - the only one that can access the SRAM is the crypto engine The last point is particularly annoying in some cases: for example on armada 370, a small region of the crypto SRAM is used to implement the cpuidle, which means you would not be able to enable both cpuidle and the CESA driver. To address that problem, we explicitly define the SRAM device in the DT and then reference the sram node from the crypto engine node. Also note that the old way of retrieving the SRAM memory region is still supported, or in other words, backward compatibility is preserved.

2015-06-18crypto: drivers - Fix Kconfig selectsHerbert Xu1-28/+13
This patch fixes a number of problems in crypto driver Kconfig entries: 1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internal and should not be used outside of the crypto API itself. 2. Do not select ALGAPI unless you use a legacy type like CRYPTO_ALG_TYPE_CIPHER. 3. Select the algorithm type that you are implementing, e.g., AEAD. 4. Do not select generic C code such as CBC/ECB unless you use them as a fallback. 5. Remove default n since that is the default default. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-16crypto: vmx - Remove duplicate PPC64 dependencyHerbert Xu1-1/+0
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 <herbert@gondor.apana.org.au>

Merge the crypto tree for 4.1 to pull in the changeset that disables algif_aead.
2015-05-11crypto: nx - add NX-842 platform frontend driverDan Streetman1-4/+6
Add NX-842 frontend that allows using either the pSeries platform or PowerNV platform driver (to be added by later patch) for the NX-842 hardware. Update the MAINTAINERS file to include the new filenames. Update Kconfig files to clarify titles and descriptions, and correct dependencies.

2015-03-23crypto: img-hash - Fix Kconfig selectionsJames Hartley1-2/+1
The Kconfig entry for CRYPTO_DEV_IMGTEC_HASH incorrectly selects CRYPTO_SHA224, which does not exist (and is covered by CRYPTO_SHA256 which covers both 224 and 256). Remove it. Also correct typo CRYPTO_ALG_API to be CRYPTO_ALGPI.
