This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too.

We currently use GFP_ATOMIC in the unaligned setkey function to allocate the temporary aligned buffer. Since setkey must be called in a sleepable context, we can use GFP_KERNEL instead. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

When we encounter an unaligned pointer we are supposed to copy it to a temporary aligned location. However the temporary buffer isn't aligned properly. This patch fixes that. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Some unaligned buffers on the stack weren't zapped properly which may cause secret data to be leaked. This patch fixes them by doing a zero memset. It is also possible for us to place random kernel stack contents in the digest buffer if a digest operation fails. This is fixed by only copying if the operation succeeded.

This patch adds a mask parameter to complement the existing type parameter. This is useful when instantiating algorithms that require a mask other than the default, e.g., ahash algorithms. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch replaces the full descriptor export with an export of the partial hash state. This allows the use of a consistent export format across all implementations of a given algorithm. This is useful because a number of cases require the use of the partial hash state, e.g., PadLock can use the SHA1 hash state to get around the fact that it can only hash contiguous data chunks.

This patch adds a new argument to crypto_alloc_instance which sets aside some space before the instance for use by algorithms such as shash that place type-specific data before crypto_alg.

This patch introduces the template->create function intended to replace the existing alloc function. The intention is for create to handle the registration directly, whereas currently the caller of alloc has to handle the registration. This allows type-specific code to be run prior to registration.

The current code uses a mix of sping_lock() & spin_lock_irqsave(). This can lead to deadlock with the correct timming & cprng_get_random() + cprng_reset() sequence. I've converted them to bottom half locks since all three user grab just a BH lock so this runs probably in softirq :) Signed-off-by: NSebastian Andrzej Siewior <sebastian@breakpoint.cc> Acked-by: NNeil Horman <nhorman@tuxdriver.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

As it stands we use chainiv for sync algorithms and eseqiv for async algorithms. However, when there is more than one CPU chainiv forces all processing to be serialised which is usually not what you want. Also, the added overhead of eseqiv isn't that great. Therefore this patch changes the default sync geniv on SMP machines to eseqiv. For the odd situation where the overhead is unacceptable then chainiv is still available as an option. Note that on UP machines chainiv is still preferred over eseqiv for sync algorithms. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>
