2015-11-17crypto: sun4i-ss - add missing statesizeLABBE Corentin
sun4i-ss implementaton of md5/sha1 is via ahash algorithms. Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero") made impossible to load them without giving statesize. This patch specifiy statesize for sha1 and md5. Fixes: 6298e948215f ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator") Cc: <stable@vger.kernel.org> # v4.3+ Tested-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-09-10crypto: sunxi-ss - Fix a possible driver hang with ciphersLABBE Corentin
The sun4i_ss_opti_poll function cipher data until the output miter have a length of 0. If the crypto API client, give more SGs than necessary this could result in an infinite loop. Fix it by checking for remaining bytes, just like sun4i_ss_cipher_poll(). Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-13crypto: sunxi-ss - Add optional reset control supportChen-Yu Tsai
On sun6i and later platforms, the reset control is split out of the clock gates. Add support for an optional reset control. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-07-20crypto: sunxi-ss - Add Allwinner Security System crypto acceleratorLABBE Corentin
Add support for the Security System included in Allwinner SoC A20. The Security System is a hardware cryptographic accelerator that support: - MD5 and SHA1 hash algorithms - AES block cipher in CBC/ECB mode with 128/196/256bits keys. - DES and 3DES block cipher in CBC/ECB mode Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
