If the architecture selected the xor function with XOR_SELECT_TEMPLATE the speed result of the do_xor_speed benchmark is of limited value. The speed measurement increases the bootup time a little, which can makes a difference for kernels used in container like virtual machines. Signed-off-by:

Currently, very few RNG drivers support single byte reads using the ->read() interface. Of the 14 drivers in drivers/char/hw_random that support this interface only three of these actually support max == 1. The other behaviours vary between return 0, return 2, return 4 and return -EIO). This is not a problem in practice because the core hw_random code never performs a read shorter than 16 bytes. The documentation for this function already contrains the alignment of the buffer pointer, so let's also guarantee that the buffer is at least as large as its alignment. This constraint is intended to be the weakest guarantee neccessary to allow driver writers to safely simplify their code. Signed-off-by:

When calling the DRBG health test in FIPS mode, the Jitter RNG is not yet present in the kernel crypto API which will cause the instantiation to fail and thus the health test to fail. As the health tests cover the enforcement of various thresholds, invoke the functions that are supposed to enforce the thresholds directly. This patch also saves precious seed. Reported-by:

Currently, in mv_cesa_{md5,sha1,sha256}_init creq->state is initialized before the call to mv_cesa_ahash_init. This is wrong because this function fills creq with zero by using memset, so its 'state' that contains the default DIGEST is overwritten. This commit fixes the issue by initializing creq->state just after the call to mv_cesa_ahash_init. Fixes: commit b0ef5106 ("crypto: marvell/cesa - initialize hash...") Signed-off-by:

So far, sub part of mv_cesa_int was responsible of dequeuing complete requests, then call the 'cleanup' operation on these reqs and call the crypto api callback 'complete'. The problem is that the transformation context 'ctx' is retrieved only once before the while loop. Which means that the wrong 'cleanup' operation might be called on the wrong type of cesa requests, it can lead to memory corruptions with this message: marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, 5a5a5a5a/5a5a5a5a (bad dma) This commit fixes the issue, by updating the transformation context for each dequeued cesa request.

The mv_cesa_ahash_cache_req() function always returns 0, which makes its return value pretty much useless. However, in addition to returning a useless value, it also returns a boolean in a variable passed by reference to indicate if the request was already cached. So, this commit changes mv_cesa_ahash_cache_req() to return this boolean. It consequently simplifies the only call site of mv_cesa_ahash_cache_req(), where the "ret" variable is no longer needed.

The mv_cesa_dma_add_op() function builds a mv_cesa_tdma_desc structure to copy the operation description to the SRAM, but doesn't explicitly initialize the destination of the copy. It works fine because the operatin description must be copied at the beginning of the SRAM, and the mv_cesa_tdma_desc structure is initialized to zero when allocated. However, it is somewhat confusing to not have a destination defined. Signed-off-by:

Threaded interrupts can perform the function of the tasklet, and much more safely too - without races when trying to take the tasklet and interrupt down on device removal. With the old code, there is a window where we call tasklet_kill(). If the interrupt handler happens to be running on a different CPU, and subsequently calls tasklet_schedule(), the tasklet will be re-scheduled for execution. Switching to a hardirq/threadirq combination implementation avoids this, and it also means generic code deals with the teardown sequencing of the threaded and non-threaded parts. Signed-off-by:

Strictly, dma_map_sg() may coalesce SG entries, but in practise on iMX hardware, this will never happen. However, dma_map_sg() can fail, and we completely fail to check its return value. So, fix this properly. Arrange the code to map the scatterlist early, so we know how many scatter table entries to allocate, and then fill them in. This allows us to keep relatively simple error cleanup paths. Signed-off-by:

caamhash contains this weird code: src_nents = sg_count(req->src, req->nbytes); dma_map_sg(jrdev, req->src, src_nents ? : 1, DMA_TO_DEVICE); ... edesc->src_nents = src_nents; sg_count() returns zero when sg_nents_for_len() returns zero or one. This means we don't need to use a hardware scatterlist. However, setting src_nents to zero causes problems when we unmap: if (edesc->src_nents) dma_unmap_sg_chained(dev, req->src, edesc->src_nents, DMA_TO_DEVICE, edesc->chained); as zero here means that we have no entries to unmap. This causes us to leak DMA mappings, where we map one scatterlist entry and then fail to unmap it. This can be fixed in two ways: either by writing the number of entries that were requested of dma_map_sg(), or by reworking the "no SG required" case. We adopt the re-work solution here - we replace sg_count() with sg_nents_for_len(), so src_nents now contains the real number of scatterlist entries, and we then change the test for using the hardware scatterlist to src_nents > 1 rather than just non-zero. This change passes my sshd, openssl tests hashing /bin and tcrypt tests. Signed-off-by:

Currently the probe function only emits an output on success when debug is specifically enabled. It would be more useful if this happens by default. Signed-off-by:

Currently the img-hash accelerator does not probe successfully due to a change in the checks made during registration with the crypto framework. This is due to import and export functions not being defined. Correct this. Signed-off-by:

Current img hash claims sys and periph gate clocks and this can be gated in system suspend scenarios. Add support for Device pm ops for img hash to gate the clocks claimed by img hash. Signed-off-by:

Move 0 length buffer to end of structure to stop overwriting fallback request data. This doesn't cause a bug itself as the buffer is never used alongside the fallback but should be changed. Signed-off-by:
