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.

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.

For SEC including a RNG block version >= 4, special initialization must occur before any descriptor that uses RNG block can be submitted. This initialization is required not only for SEC with version greater than 5.0, but for SEC with RNG version >=4. There may be a case where RNG has already been instantiated by u-boot or boot ROM code.In such SoCs, if RNG is initialized again SEC would returns "Instantiation error". Hence, the initialization status of RNG4 should be also checked before doing RNG init.

This change is required for post SEC-5.0 devices which have RNG4. Setting RDB in security configuration register allows CAAM to use the "Random Data Buffer" to be filled by a single request. The Random Data Buffer is large enough for ten packets to get their IVs from a single request. If the Random Data Buffer is not enabled, then each IV causes a separate request, and RNG4 hardware cannot keep up resulting in lower IPSEC throughput if random IVs are used.

2013-03-21crypto: sahara - Add driver for SAHARA2 accelerator.Javier Martin3-0/+1081
SAHARA2 HW module is included in the i.MX27 SoC from Freescale. It is capable of performing cipher algorithms such as AES, 3DES..., hashing and RNG too. This driver provides support for AES-CBC and AES-ECB by now.

2013-03-21Revert "crypto: caam - add IPsec ESN support"Horia Geanta2-26/+2
This reverts commit 891104ed008e8646c7860fe5bc70b0aac55dcc6c. Current IPsec ESN implementation for authencesn(cbc(aes), hmac(sha)) (separate encryption and integrity algorithms) does not conform to RFC4303. ICV is generated by hashing the sequence SPI, SeqNum-High, SeqNum-Low, IV, Payload instead of SPI, SeqNum-Low, IV, Payload, SeqNum-High.

2013-03-10crypto: caam - fix typo "CRYPTO_AHASH"Paul Bolle1-1/+1
The Kconfig entry for CAAM's hash algorithm implementations has always selected CRYPTO_AHASH. But there's no corresponding Kconfig symbol. It seems it was intended to select CRYPTO_HASH, like other crypto drivers do. That would apparently (indirectly) select CRYPTO_HASH2, which would enable the ahash functionality this driver uses.

2013-03-10crypto: omap-aes - Use pm_runtime_put instead of pm_runtime_put_sync in taskletJoel A Fernandes1-1/+1
After DMA is complete, the omap_aes_finish_req function is called as a part of the done_task tasklet. During this its atomic and any calls to pm functions should not assume they wont sleep. The patch replaces a call to pm_runtime_put_sync (which can sleep) with pm_runtime_put thus fixing a kernel panic observed on AM33xx SoC during AES operation. Tested on an AM33xx SoC device (beaglebone board). To reproduce the problem, I used the tcrypt kernel module as: modprobe tcrypt sec=2 mode=500 Signed-off-by: Joel A Fernandes <[email protected]> Cc: David S.
