2016-03-17crypto: marvell/cesa - fix memory leakBoris BREZILLON2-69/+20
Crypto requests are not guaranteed to be finalized (->final() call), and can be freed at any moment, without getting any notification from the core. This can lead to memory leaks of the ->cache buffer. Make this buffer part of the request object, and allocate an extra buffer from the DMA cache pool when doing DMA operations. As a side effect, this patch also fixes another bug related to cache allocation and DMA operations. When the core allocates a new request and import an existing state, a cache buffer can be allocated (depending on the state). The problem is, at that very moment, we don't know yet whether the request will use DMA or not, and since everything is likely to be initialized to zero, mv_cesa_ahash_alloc_cache() thinks it should allocate a buffer for standard operation. But when mv_cesa_ahash_free_cache() is called, req->type has been set to CESA_DMA_REQ in the meantime, thus leading to an invalind dma_pool_free() call (the buffer passed in argument has not been allocated from the pool).

When (!ctx->bufcnt && !(ctx->flags & SHA_FLAGS_PAD)), the former source code used to set the SHA_FLAGS_BUSY without checking whether this flag was already set.

Based on commit 434b421241f2d0 ("crypto: caam - avoid needlessly saving and restoring caam_hash_ctx") from Russell King. When exporting and importing the hash state, we will only export and import into hashes which share the same struct crypto_ahash pointer. (See hash_accept->af_alg_accept->hash_accept_parent.) This means that saving the sahara_ctx structure on export, and restoring it on import is a waste of resources. So, remove this code.

2016-01-25crypto: atmel-sha - fix a race between the 'done' tasklet and the crypto clientCyrille Pitchen1-6/+13
The 'done' tasklet handler used to check the 'BUSY' flag to either finalize the processing of a crypto request which had just completed or manage the crypto queue to start the next crypto request. On request R1 completion, the driver calls atmel_sha_finish_req(), which: 1 - clears the 'BUSY' flag since the hardware is no longer used and is ready again to process new crypto requests. 2 - notifies the above layer (the client) about the completion of the asynchronous crypto request R1 by calling its base.complete() callback. 3 - schedules the 'done' task to check the crypto queue and start to process the next crypto request (the 'BUSY' flag is supposed to be cleared at that moment) if such a pending request exists. However step 2 might wake the client up so it can now ask our driver to process a new crypto request R2. This request is enqueued by calling the atmel_sha_handle_queue() function, which sets the 'BUSY' flags then starts to process R2. If the 'done' tasklet, scheduled by step 3, runs just after, it would see that the 'BUSY' flag is set then understand that R2 has just completed, which is wrong! So the state of 'BUSY' flag is not a proper way to detect and handle crypto request completion. This patch fixes this race condition by using two different tasklets, one to handle the crypto request completion events, the other to manage the crypto queue if needed.

2016-01-25crypto: atmel-sha - fix crash when computing digest on empty messageCyrille Pitchen1-0/+1
This patch fixes a crash which occured during the computation of the digest of an empty message. Indeed, when processing an empty message, the atmel_sha_handle_queue() function was never called, hence the dd->req pointer remained uninitialized. Later, when the atmel_sha_final_req() function was called, it used to crash while using this uninitialized dd->req pointer. Hence this patch adds missing initializations of dd->req before calls of the atmel_sha_final_req() function. This bug prevented us from passing the tcrypt test suite on SHA algo.
