2017-06-22crypto: cavium/nitrox - dma_mapping_error() returns boolDan Carpenter1-6/+9
We want to return negative error codes here, but we're accidentally propogating the "true" return from dma_mapping_error(). Fixes: 14fa93cdcd9b ("crypto: cavium - Add support for CNN55XX adapters.") Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Herbert Xu <[email protected]>

of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the non-const structs as const.

2017-06-20crypto: vmx - remove unnecessary checkTudor-Dan Ambarus4-24/+4
You can't reach init() if parent alg_name is invalid. Moreover, cypto_alloc_base() will return ENOENT if alg_name is NULL. Found while grasping the fallback mechanism. Signed-off-by: Tudor Ambarus <[email protected]> Signed-off-by: Herbert Xu <[email protected]>

2017-06-20crypto: inside-secure - use the base_end pointer in ring rollbackAntoine Ténart1-1/+1
A base_end pointer is set and provided. Use it in the ring rollback function to avoid using build-in defines. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - increase the batch sizeAntoine Ténart1-1/+1
Increase the batch size to the maximum number of requests a ring can handle at a time (its size). This is possible now that the request queues are per hw ring. This improves performances. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - only dequeue when neededAntoine Ténart1-3/+3
This force the need_dequeue flag to be unset whenever the dequeue function is called, to avoid calling it when it is not necessary. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - get the backlog before dequeueing the requestAntoine Ténart1-1/+1
Get the backlog before dequeuing the request otherwise we'll miss the first request in line. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - stop requeueing failed requestsAntoine Ténart1-8/+10
This update the dequeue function of the inside-secure safexcel driver so that failed requests aren't requeued when they fail (for whatever reason, which can be because the hw ring is full). Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - use one queue per hw ringAntoine Ténart4-85/+89
Update the inside-secure safexcel driver from using one global queue to one queue per hw ring. This ease the request management and keep the hw in sync with what's done in sw. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - update the context and request laterAntoine Ténart2-8/+7
This move the context and request updates at the end of the cipher and hash send() functions. This way the context and request fields are set only when everything else was successful in the send() functions.

2017-06-20crypto: inside-secure - align the cipher and hash send functionsOfer Heifetz1-1/+1

2017-06-20crypto: inside-secure - optimize DSE bufferability controlIgal Liberman2-0/+2

2017-06-20crypto: inside-secure - enable single WR in DSE configurationIgal Liberman2-0/+2
When enable_single_wr is not enabled, the DSE will only write those parts of a result descriptor that need updating, which means a final result descriptor will be written in 2 or 3 smaller transfers. When enable_single_wr is enabled the DSE will combine these 2-3 updates into one large write transfer, generally improving performance.

2017-06-20crypto: inside-secure - fix incorrect DSE data cache settingAntoine Ténart1-1/+1

The run-time self-tests fail quite early, as soon as the input block size is larger than 64 bytes: alg: hash: Test 4 failed for sha1-sun4i-ss 00000000: b9 c9 1e 52 c0 26 d8 39 81 ff f2 3c 99 b1 27 b2 00000010: 30 d6 c9 85 One thing to notice is the value of the last word, which is the one expected (it can sometime be the last two words). The datasheet isn't very clear about when the digest is ready to retrieve and is seems the bit SS_DATA_END is cleared when the digest was computed *but* that doesn't mean the digest is ready to retrieve in the registers. A ndelay(1) is added before reading the computed digest to ensure it is available in the SS_MD[] registers.
