crypto: caam - fix AEAD givenc descriptors

2017-01-13T01:56:53Z

[ Upstream commit d128af17876d79b87edf048303f98b35f6a53dbc ] The AEAD givenc descriptor relies on moving the IV through the output FIFO and then back to the CTX2 for authentication. The SEQ FIFO STORE could be scheduled before the data can be read from OFIFO, especially since the SEQ FIFO LOAD needs to wait for the SEQ FIFO LOAD SKIP to finish first. The SKIP takes more time when the input is SG than when it's a contiguous buffer. If the SEQ FIFO LOAD is not scheduled before the STORE, the DECO will hang waiting for data to be available in the OFIFO so it can be transferred to C2. In order to overcome this, first force transfer of IV to C2 by starting the "cryptlen" transfer first and then starting to store data from OFIFO to the output buffer.

crypto: caam - add support for givencrypt cbc(des) and cbc(des3_ede)

2014-11-12T14:14:32Z

Merge DES Cipher Block Chaining mode (CBC) and Triple DES Cipher Block Chaining mode (CBC) algorithms from ablkcipher to givencrypt. Signed-off-by: Catalin Vasile Signed-off-by: Herbert Xu

crypto: caam - add support for givencrypt cbc(aes) and rfc3686(ctr(aes))

2014-11-06T15:15:05Z

Add support for one-shot givencrypt algorithms. Givencrypt algorithms will generate their IV and encrypt data within the same shared job descriptors. Current algorithms merged from ablkcipher to givencrypt are: - AES Cipher Block Chaining (CBC) - AES Counter Mode (CTR) compliant with RFC3686 Signed-off-by: Catalin Vasile Signed-off-by: Herbert Xu

crypto: caam - add support for rfc3686 with authenc md5, sha1 and sha2

2014-11-06T15:15:04Z

Add support for AES Counter Mode (CTR) compliant with RFC3686 to be used along with authenc algorithms (md5, sha1, sha224, sha256, sha384, sha512) as one-shot aead algorithms. Signed-off-by: Catalin Vasile Signed-off-by: Herbert Xu

crypto: caam - add support for rfc3686(ctr(aes))

2014-11-06T15:15:04Z

Add support for Advanced Encryption Standard (AES) in Counter Mode (CTR) as provided in IPsec implementation standard RFC3686. ablkcipher shared descriptors now save context registers after job execution. This is used to load Nonce specific to RFC3686 only at first execution of shared job descriptor. Signed-off-by: Catalin Vasile Signed-off-by: Herbert Xu

Add AES-GMAC as an IPSec ESP mechanism to provide data origin authentication, but not confidentiality. This method is referred as ENCR_NULL_AUTH_AES_GMAC. Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu

crypto: caam - fix output sequence contiguity check

2014-11-06T15:15:00Z

This patch fixes the assumption that output sequence is not contiguous when input sequence is not contiguous and in-place encryption is done. Output sequence does not need to be contiguous with associated data. Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu
