2010-04-26crypto: authenc - Add EINPROGRESS checkHerbert Xu1-5/+11
When Steffen originally wrote the authenc async hash patch, he correctly had EINPROGRESS checks in place so that we did not invoke the original completion handler with it. Unfortuantely I told him to remove it before the patch was applied. As only MAY_BACKLOG request completion handlers are required to handle EINPROGRESS completions, those checks are really needed. This patch restores them. Reported-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-03-03crypto: authenc - Move saved IV in front of the ablkcipher requestSteffen Klassert1-11/+14
In crypto_authenc_encrypt() we save the IV behind the ablkcipher request. To save space on the request, we overwrite the ablkcipher request with a ahash request after encryption. So the IV may be overwritten by the ahash request. This patch fixes this by placing the IV in front of the ablkcipher/ahash request.

2010-03-03crypto: hash - Fix handling of unaligned buffersSzilveszter Ördög1-1/+0
The correct way to calculate the start of the aligned part of an unaligned buffer is: offset = ALIGN(offset, alignmask + 1); However, crypto_hash_walk_done() has: offset += alignmask - 1; offset = ALIGN(offset, alignmask + 1); which actually skips a whole block unless offset % (alignmask + 1) == 1. This patch fixes the problem. Signed-off-by: Szilveszter Ördög <slipszi@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2009-11-20async_tx: build-time toggling of async_{syndrome,xor}_val dma supportDan Williams3-6/+28
ioat3.2 does not support asynchronous error notifications which makes the driver experience latencies when non-zero pq validate results are expected. Provide a mechanism for turning off async_xor_val and async_syndrome_val via Kconfig. This approach is generally useful for any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like to force the async_tx api to fall back to the synchronous path for certain operations.

2009-11-16crypto: gcm - fix another complete call in complete fuctionHuang Ying1-34/+73
The flow of the complete function (xxx_done) in gcm.c is as follow: void complete(struct crypto_async_request *areq, int err) { struct aead_request *req = areq->data; if (!err) { err = async_next_step(); if (err == -EINPROGRESS || err == -EBUSY) return; } complete_for_next_step(areq, err); } But *areq may be destroyed in async_next_step(), this makes complete_for_next_step() can not work properly. To fix this, one of following methods is used for each complete function. - Add a __complete() for each complete(), which accept struct aead_request *req instead of areq, so avoid using areq after it is destroyed. - Expand complete_for_next_step(). The fixing method is based on the idea of Herbert Xu. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2009-10-20async_tx: fix asynchronous raid6 recovery for ddf layoutsDan Williams1-30/+56
The raid6 recovery code currently requires special handling of the 4-disk and 5-disk recovery scenarios for the native layout. Quoting from commit 0a82a623: In these situations the default N-disk algorithm will present 0-source or 1-source operations to dma devices. To cover for dma devices where the minimum source count is 2 we implement 4-disk and 5-disk handling in the recovery code. The ddf layout presents disks=6 and disks=7 to the recovery code in these situations. Instead of looking at the number of disks count the number of non-zero sources in the list and call the special case code when the number of non-failed sources is 0 or 1.
