2017-08-22crypto: inside-secure - fix an error handling path in safexcel_probe()Christophe Jaillet1-2/+3
'ret' is known to be 0 at this point. If 'safexcel_request_ring_irq()' fails, it returns an error code. Return this value instead of 0 which means success. Signed-off-by: Christophe JAILLET <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-08-03crypto: inside-secure - fix the sha state length in hmac_sha1_setkeyAntoine Ténart1-1/+1
A check is performed on the ipad/opad in the safexcel_hmac_sha1_setkey function, but the index used by the loop doing it is wrong. It is currently the size of the state array while it should be the size of a sha1 state. This patch fixes it.

2017-08-03crypto: inside-secure - fix invalidation check in hmac_sha1_setkeyAntoine Ténart1-3/+3
The safexcel_hmac_sha1_setkey function checks if an invalidation command should be issued, i.e. when the context ipad/opad change. This checks is done after filling the ipad/opad which and it can't be true. The patch fixes this by moving the check before the ipad/opad memcpy operations.

2017-07-18crypto: inside-secure - do not parse the dma mask from dtAntoine Ténart1-4/+1
Remove the dma mask parsing from dt as this should not be encoded into the engine device tree node. Keep the fallback value for now, which should work for the boards already supported upstream.

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
The cipher and hash send functions both set the results variable, to be used later by the caller. Align the way they're setting this variable. Signed-off-by: Ofer Heifetz <[email protected]> Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - optimize DSE bufferability controlIgal Liberman2-0/+2
Configure the data write bufferability to always buffer packets in the DSE. This change slightly improves performance. Signed-off-by: Igal Liberman <[email protected]> Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
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
Set the correct value to the DSE data cache, using WR_CACHE_3BITS instead of RD_CACHE_3BITS. This fixes an incorrect setting and helps improving performances.

2017-06-20crypto: inside-secure - fix the ring wr_cache offsetAntoine Ténart1-1/+1
The EIP197_HIA_xDR_CFG_WR_CACHE macro was defined to use an offset of 23, which is wrong as it's actually 25. Fix this. Reported-by: Igal Liberman <[email protected]> Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-20crypto: inside-secure - use hmac ipad/opad constantsAntoine Ténart1-2/+3
Replace the hmac ipad/opad values by their defined constants. Signed-off-by: Antoine Tenart <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2017-06-10crypto: inside-secure - add SafeXcel EIP197 crypto engine driverAntoine Ténart6-0/+3262
Add support for Inside Secure SafeXcel EIP197 cryptographic engine, which can be found on Marvell Armada 7k and 8k boards. This driver currently implements: ecb(aes), cbc(aes), sha1, sha224, sha256 and hmac(sah1) algorithms. Two firmwares are needed for this engine to work. Their are mostly used for more advanced operations than the ones supported (as of now), but we still need them to pass the data to the internal cryptographic engine.
