In doing so, sha512 sized keys would not fit with the current
descriptor inlining mechanism, so we now calculate whether keys
should be referenced instead by pointers in the shared descriptor.also, use symbols for descriptor text lengths, and, ahem, unmap and
free key i/o memory in cra_exit.Signed-off-by: Kim 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.Signed-off-by: Kim Phillips

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

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: 1i.e, 302 characters.

prior to jr_reset to avoid 'got IRQ but nobody cared' messages.- disable IRQs in h/w to avoid contention between reset and

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: Dmitry Kasatkin

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: Jamie Iles

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
