* crypto: marvell - Update cache with input sg only when it is unmappedRomain Perier2016-07-281-6/+6
| | | | | | | | | | | | | | | So far, the cache of the ahash requests was updated from the 'complete' operation. This complete operation is called from mv_cesa_tdma_process before the cleanup operation, which means that the content of req->src can be read and copied when it is still mapped. This commit fixes the issue by moving this cache update from mv_cesa_ahash_complete to mv_cesa_ahash_req_cleanup, so the copy is done once the sglist is unmapped.

* crypto: marvell - Don't chain at DMA level when backlog is disabledRomain Perier2016-07-281-3/+4
| | | | | | | | | | | | | The flag CRYPTO_TFM_REQ_MAY_BACKLOG is optional and can be set from the user to put requests into the backlog queue when the main cryptographic queue is full. Before calling mv_cesa_tdma_chain we must check the value of the return status to be sure that the current request has been correctly queued or added to the backlog.

* crypto: marvell - Fix memory leaks in TDMA chain for cipher requestsRomain Perier2016-07-281-8/+6
| | | | | | | | | | | | So far in mv_cesa_ablkcipher_dma_req_init, if an error is thrown while the tdma chain is built there is a memory leak. This issue exists because the chain is assigned later at the end of the function, so the cleanup function is called with the wrong version of the chain.

In particular, if we're on an SG entry spanning multiple pages where the last page is not a full page, we will incorrectly skip calling pagedone on the second last page.

They are accessible through the top-level skcipher interface, along with ablkcipher/blkcipher algorithms and instances.

The Coccinelle semantic patch that makes this change is as follows: // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
