f4c4cd6d14 Revert "crypto: camellia - Use kernel-provided bitops, unaligned access helpers"
This reverts commit bd699f2df6,
which causes camellia to fail the included self-test vectors.
It has also been confirmed that it breaks existing encrypted
disks using camellia.

de24125dd0 async_tx: fix the bug in async_tx_run_dependencies
Should clear the next pointer of the TX if we are sure that the
next TX (say NXT) will be submitted to the channel too. Overwise,
we break the chain of descriptors, because we lose the information
about the next descriptor to run. So next time, when invoke
async_tx_run_dependencies() with TX, it's TX->next will be NULL, and
NXT will be never submitted.

a697690bec crypto: authenc - Avoid using clobbered request pointer
Authenc works in two stages for encryption, it first encrypts and
then computes an ICV.  The context memory of the request is used
by both operations.  The problem is that when an asynchronous
encryption completes, we will compute the ICV and then reread the
context memory of the encryption to get the original request.

It just happens that we have a buffer of 16 bytes in front of the
request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger
the bug.  However, any attempt to uses a larger ICV instantly kills
the machine when the first asynchronous encryption is completed.

This patch fixes this by saving the request pointer before we start
the ICV computation.

f176e632ef crypto: tcrypt - Fix AEAD chunk testing
My changeset 4b22f0ddb6

	crypto: tcrpyt - Remove unnecessary kmap/kunmap calls

introduced a typo that broke AEAD chunk testing.  In particular,
axbuf should really be xbuf.

There is also an issue with testing the last segment when encrypting.
The additional part produced by AEAD wasn't tested.  Similarly, on
decryption the additional part of the AEAD input is mistaken for
corruption.

669ab0b210 async_tx: fix handling of the "out of descriptor" condition in async_xor
Ensure forward progress is made when a dmaengine driver is unable to
allocate an xor descriptor by breaking the dependency chain with
async_tx_quisce() and issue any pending descriptors.

Tested with iop-adma by setting device->max_xor = 2 to force multiple
calls to device_prep_dma_xor for each call to async_xor and limiting the
descriptor slot pool to 5.  Discovered that the minimum descriptor pool
size for iop-adma is 2 * iop_chan_xor_slot_cnt(device->max_xor) + 1.

1e55db2d6b async_tx: ensure the xor destination buffer remains dma-mapped
When the number of source buffers for an xor operation exceeds the hardware
channel maximum async_xor creates a chain of dependent operations.  The result
of one operation is reused as an input to the next to continue the xor
calculation.  The destination buffer should remain mapped for the duration of
the entire chain.  To provide this guarantee the code must no longer be allowed
to fallback to the synchronous path as this will preclude the buffer from being
unmapped, i.e. the dma-driver will potentially miss the descriptor with
!DMA_COMPL_SKIP_DEST_UNMAP.

ca786dc738 crypto: hash - Fixed digest size check
The digest size check on hash algorithms is incorrect.  It's
perfectly valid for hash algorithms to have a digest length
longer than their block size.  For example crc32c has a block
size of 1 and a digest size of 4.  Rather than having it lie
about its block size, this patch fixes the checks to do what
they really should which is to bound the digest size so that
code placing the digest on the stack continue to work.

HMAC however still needs to check this as it's only defined
for such algorithms.

Patch to add checking  of DES3 test vectors using CBC mode.  FIPS-140-2

following command:

	openssl enc -des_ede_cbc -P

input and output values were generated by repeating the string "Too many

openssl using the aformentioned key.  Tested successfully by myself
