crypto: omap-aes - Fix support for unequal lengths

2015-05-06T20:04:08+00:00

commit 6d7e7e02a044025237b6f62a20521170b794537f upstream.

For cases where total length of an input SGs is not same as
length of the input data for encryption, omap-aes driver
crashes. This happens in the case when IPsec is trying to use
omap-aes driver.

To avoid this, we copy all the pages from the input SG list
into a contiguous buffer and prepare a single element SG list
for this buffer with length as the total bytes to crypt, which is
similar thing that is done in case of unaligned lengths.

Merge branch 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma

2015-02-18T16:49:20+00:00

Pull dmaengine updates from Vinod Koul:
 "This update brings:

   - the big cleanup up by Maxime for device control and slave
     capabilities.  This makes the API much cleaner.

   - new IMG MDC driver by Andrew

   - new Renesas R-Car Gen2 DMA Controller driver by Laurent along with
     bunch of fixes on rcar drivers

   - odd fixes and updates spread over driver"

crypto: caam - pair irq map and dispose in the same function

2015-01-26T00:34:25+00:00

irq_dispose_mapping is not called on all error paths from caam_jr_init.
This takes care of several clean-up issues by performing resource
clean-up and allocation at the same level.

ICV check failures are part of normal operation;
leave user notification up to the higher levels,
as is done in s/w algorithm implementations.

crypto: replace scatterwalk_sg_next with sg_next

2015-01-26T00:34:22+00:00

Modify crypto drivers to use the generic SG helper since
both of them are equivalent and the one from crypto is redundant.
