2010-05-05raid6: fix recovery performance regressionDan Williams
The raid6 recovery code should immediately drop back to the optimized synchronous path when a p+q dma resource is not available. Otherwise we run the non-optimized/multi-pass async code in sync mode. Verified with raid6test (NDISKS=255) Applies to kernels >= 2.6.32. Cc: <stable@kernel.org> Acked-by: NeilBrown <neilb@suse.de> Reported-by: H.

2010-04-26crypto: authenc - Add EINPROGRESS checkHerbert Xu
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>
2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-03crypto: authenc - Move saved IV in front of the ablkcipher requestSteffen Klassert
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 Ördög
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.

Add __percpu sparse annotations to places which didn't make it in one of the previous patches. All converions are trivial. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds.

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>
