* crypto: ccp - Remove VLA usage of skcipherKees Cook2018-09-281-1/+1
| | | | | | | | | | | | | | In the quest to remove all stack VLA usage from the kernel[1], this replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(), which uses a fixed stack size.

* crypto: ccp - Move HMAC calculation down to ccp ops fileTom Lendacky2014-02-091-4/+4
| | | | | | | | | | Move the support to perform an HMAC calculation into the CCP operations file. This eliminates the need to perform a synchronous SHA operation used to calculate the HMAC. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | When performing a hash operation if the amount of data buffered and a request at or near the maximum data length is received then the length calcuation could wrap causing an error in executing the hash operation. Fix this by using a u64 type for the input and output data lengths in all CCP operations. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
