2011-09-19HCL driver implementation (hash).Robert Marklund
Major refactoring, checkpatch fixes, documentation of functions, structures, enums. Also moved a lot of code from hash_alg.c to hash_core.c. Fixed problem with incorrect digest when doing HMAC calculations. The problem was that the function that did message pad seems to handle padding for keys incorrectly. Now we do not say how many valid bits there are in the last word when it comes to the key and then the hardware seems to handle the key correctly. Fixed contextsaving so hmac(sha1) passes. There was an if statement checking the DINF bit which was never set. I have removed this and then contextsaving for hmac(sha1) is working.

2011-05-19crypto: caam - fix decryption shared vs. non-shared key settingKim Phillips
Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.

2011-05-03crypto: caam - handle interrupt lines shared across ringsKim Phillips
- add IRQF_SHARED to request_irq flags to support parts such as the p1023 that has one IRQ line per couple of rings. - resetting a job ring triggers an interrupt, so move request_irq prior to jr_reset to avoid 'got IRQ but nobody cared' messages. - disable IRQs in h/w to avoid contention between reset and interrupt status - delete invalid comment - if there were incomplete jobs, module would be in use, preventing an unload.

2011-04-26crypto: omap-sham - hmac calculation bug fix for sha1 base hashDmitry Kasatkin
This patch fixes 2 hmac inter-dependent bugs. 1. "omap-sham: hash-in-progress is stored in hw format" commit introduced optimization where temporary hash had been stored in OMAP specific format (big endian). For SHA1 it is different to real hash format, which is little endian. Final HMAC value was calculated using incorrect hash. Because CONFIG_CRYPTO_MANAGER_TESTS was disabled this error remained unnoticed. After enabling this option, bug has been found. 2. HMAC was calculated using temporrary hash value. For a single-request updates, temporary hash was the final one and HMAC result was correct. But in fact only the final hash had to be used. All crypto tests for HMAC produces only single request and could not catch the problem. This problem is fixed here.
