commit c35828ea906a7c76632a0211e59c392903cd4615 upstream.

Immediate packets sent to hardware should include the work
request length in calculating the flits. WR occupy one flit and
if not accounted result in invalid request which stalls the HW
queue.

crypto: cavium/nitrox - fix a DMA pool free failure 2019-01-09T16:45:59+00:00 Wenwen Wang wang6495@umn.edu 2018-10-19T00:50:43+00:00 b8c2f908c3ef353c04ab6a49a23265729c66ed34 commit 7172122be6a4712d699da4d261f92aa5ab3a78b8 upstream. In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc() to hold the crypto context. The meta data of the DMA pool, including the pool used for the allocation 'ndev->ctx_pool' and the base address of the DMA pool used by the device 'dma', are then stored to the beginning of the pool. These meta data are eventually used in crypto_free_context() to free the DMA pool through dma_pool_free(). However, given that the DMA pool can also be accessed by the device, a malicious device can modify these meta data, especially when the device is controlled to deploy an attack. This can cause an unexpected DMA pool free failure. To avoid the above issue, this patch introduces a new structure crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold the meta data information of the DMA pool after the allocation. Note that the original structure ctx_hdr is not changed to ensure the compatibility.

commit 7172122be6a4712d699da4d261f92aa5ab3a78b8 upstream.

In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc()
to hold the crypto context. The meta data of the DMA pool, including the
pool used for the allocation 'ndev->ctx_pool' and the base address of the
DMA pool used by the device 'dma', are then stored to the beginning of the
pool. These meta data are eventually used in crypto_free_context() to free
the DMA pool through dma_pool_free(). However, given that the DMA pool can
also be accessed by the device, a malicious device can modify these meta
data, especially when the device is controlled to deploy an attack. This
can cause an unexpected DMA pool free failure.

To avoid the above issue, this patch introduces a new structure
crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold
the meta data information of the DMA pool after the allocation. Note that
the original structure ctx_hdr is not changed to ensure the compatibility.
