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.

Loading fpu without aesni-intel does nothing. Loading aesni-intel without fpu causes modes like xts to fail. (Unloading aesni-intel will restore those modes.) One solution would be to make aesni-intel depend on fpu, but it seems cleaner to just combine the modules. This is probably responsible for bugs like: https://bugzilla.redhat.com/show_bug.cgi?id=589390Signed-off-by:

This also makes the dummy scatterlist in mv_hash_final() needless, so drop it. XXX: should this routine be made pulicly available? There are probably other users with their own implementations. Signed-off-by:

On one hand, the digest state registers need to be set only when actually using the crypto engine. On the other hand, there is a check for ctx->first_hash in mv_process_hash_current() already, so use that. Signed-off-by:

The main goal was to have it not do anything when a zero len parameter was being passed (which could lead to a null pointer dereference, as in this case p->src_sg is null, either). Using the min() macro, the lower part of the loop gets simpler, too. Signed-off-by:

The code in mv_hash_final is actually a superset of mv_hash_finup's body. Since the driver works fine without, drop it. Signed-off-by:

during recent descriptor development, an Invalid Sequence Command error triggered a: BUG: recent printk recursion! due to insufficient memory allocated for the error text. The Invalid Sequence Command error text is the longest. The length of the maximum error string is computed as the sum of: "DECO: ": 6 "jump tgt desc idx 255: ": 23 Invalid Sequence Command text: 272 zero termination character: 1 i.e, 302 characters.

- 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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

- all the integration parameters have been captured by the binding. - the block name really uniquely identifies this hardware. Some advocate putting SoC names everywhere in case software needs to work around some chip-specific bug, but more precise SoC information already exists in SVR, and board information already exists in the top-level device tree node. Note that sometimes the SoC name is a worse identifier than the block version, as the block version can change between revisions of the same SoC. As a matter of historical reference, neither SEC versions 2.x nor 3.x (driven by talitos) ever needed CHIP references. Signed-off-by:
