2011-05-03crypto: caam - handle interrupt lines shared across ringsKim Phillips1-26/+20
- 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 Kasatkin1-40/+31
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.

2011-03-27crypto: picoxcell - fix possible status FIFO overflowJamie Iles1-29/+35
The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status FIFO. The command FIFO takes the requests that are to be performed and the status FIFO reports the results. It is possible to get into the situation where there are more free spaces in the command FIFO than the status FIFO if we don't empty the status FIFO quickly enough resulting in a possible overflow of the status FIFO. This can result in incorrect status being reported in the status FIFO. Make sure that when we are submitting requests the number of requests that have been dispatched but not yet popped from the status FIFO does not exceed the size of a single FIFO.

Add new SHA-1/256 module that never needs any fallback and just calls the PadLock hardware instruction supported from VIA Nano processors to implement the "update" and "final" function. They are respectively named "sha1_alg_nano" and "sha256_alg_nano", and will be used on any VIA Nano processor or the later ones. On VIA C7 CPU, the "sha1_alg" and "sha256_alg" modules will still be used as before.

The SEC4 supercedes the SEC2.x/3.x as Freescale's Integrated Security Engine. Its programming model is incompatible with all prior versions of the SEC (talitos). The SEC4 is also known as the Cryptographic Accelerator and Assurance Module (CAAM); this driver is named caam. This initial submission does not include support for Data Path mode operation - AEAD descriptors are submitted via the job ring interface, while the Queue Interface (QI) is enabled for use by others. Only AEAD algorithms are implemented at this time, for use with IPsec. Many thanks to the Freescale STC team for their contributions to this driver.

But if no hash calculation error happens and client will not call crypto_ahash_final() at all, then internal buffer will not be freed, and clocks will not be disabled. This patch provides support for atomic crypto_ahash_update() call. Clocks are now enabled and disabled per update request. Data buffer is now allocated as a part of request context.
