In function talitos_probe(), it will jump to err_out when getting an error in talitos_probe_irq(). Then the uninitialized list head priv->alg_list will be used in function talitos_remove(). In this case we would get a call trace like the following. So move up the initialization of priv->alg_list.

2014-02-09crypto: caam - Fix job ring discovery in controller driverNitesh Lal
The SEC Controller driver creates platform devices for it's child job ring nodes. Currently the driver uses for_each_compatible routine which traverses the whole device tree to create the job rings for the platform device. The patch changes this to search for the compatible property of job ring only in the child nodes i.e., the job rings are created as per the number of children associated with the crypto node.

2014-02-09crypto: dcp - Move the AES operation type from actx to rctxMarek Vasut
Move the AES operation type and mode from async crypto context to crypto request context. This allows for recycling of the async crypto context for different kinds of operations. I found this problem when I used dm-crypt, which uses the same async crypto context (actx) for both encryption and decryption requests. Since the requests are enqueued into the processing queue, immediatelly storing the type of operation into async crypto context (actx) caused corruption of this information when encryption and decryption operations followed imediatelly one after the other. When the first operation was dequeued, the second operation was already enqueued and overwritten the type of operation in actx, thus causing incorrect result of the first operation. Fix this problem by storing the type of operation into the crypto request context. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David S.

Remove the old DCP driver as it had multiple severe issues. The driver will be replaced by a more robust implementation.

2013-12-05crypto: omap-aes - add error check for pm_runtime_get_syncNishanth Menon
The AES driver currently assumes that pm_runtime_get_sync will always succeed, which may not always be true, so add error handling for the same. This scenario was reported in the following bug: place. https://bugzilla.kernel.org/show_bug.cgi?id=66441 Reported-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2013-12-05crypto: talitos - fix locating offending descriptor in error pathHoria Geanta
Commit 3e721aeb3df3816e283ab18e327cd4652972e213 ("crypto: talitos - handle descriptor not found in error path") tried to address the fact that CDPR (Current Descriptor Pointer Register) is unreliable. As it turns out, there are still issues in the function detecting the offending descriptor: -only 32 bits of the descriptor address are read, however the address is 36-bit - since reset_channel() initializes channels with EAE (extended address) bit set -reading CDPR can return zero in cur_desc; when searching the channel fifo for this address, cur_desc == dma_desc (= 0) case might happen, leading to an oops when trying to return desc->hdr (desc is zero) -read channel's .tail only once; the tail is a moving target; use a local variable for the end of search condition Signed-off-by: Lei Xu <Lei.Xu@freescale.com> Signed-off-by: Horia Geanta <horia.geanta@freescale.com> Tested-by: Kalyani Chowdhury <Kalyani.Chowdhury@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2013-12-05crypto: omap-sham - Only release DMA channel if successfully requestedMark A. Greer
In omap_sham_probe() and omap_sham_remove(), 'dd->dma_lch' is released without checking to see if it was successfully requested or not. This is a bug and was identified and reported by Dan Carpenter here: http://www.spinics.net/lists/devicetree/msg11023.html Add code to only release 'dd->dma_lch' when its not NULL (that is, when it was successfully requested).
