Horia Geant? f074f7b103 crypto: tcrypt - avoid mapping from module image addresses
The output buffer in test_ahash_speed will point to an address located
within the tcrypt module image.
This causes problems when trying to DMA map the buffer.
For e.g. on ARM-based LS1021A, a page fault occurs within the
DMA API when trying to access the struct page returned by
virt_to_page(output):

Horia Geant? 007ee8dec6 crypto: tcrypt - fix uninit sg entries in test_acipher_speed
Commit 5be4d4c94b ("crypto: replace scatterwalk_sg_next with sg_next")
did not consider the fact that scatterwalk_sg_next() was looking at
sg entry length, while sg_next() looks at the "chained" sg bit.

This should have no effect in theory. However in practice, there are
cases where the sg table is initialized to a number of entries and
some of them are not properly configured. While scatterwalk_sg_next()
would have returned NULL (since sg length = 0 and sg page_link = 0),
sg_next() happily returns the next unconfigured sg entry.

  The original code always sets the last scatterlist to a fraction of a

Rabin Vincent 8a45ac12ec crypto: testmgr - don't use interruptible wait in tests
tcrypt/testmgr uses wait_for_completion_interruptible() everywhere when
it waits for a request to be completed.  If it's interrupted, then the
test is aborted and the request is freed.

However, if any of these calls actually do get interrupted, the result
will likely be a kernel crash, when the driver handles the now-freed
request.  Use wait_for_completion() instead.

Now that module softdeps are in the kernel we can use that to resolve
the boot issue which cause the revert.

Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.

Tim Chen 39761214ee crypto: crct10dif - Simple correctness and speed test for CRCT10DIF hash
These are simple tests to do sanity check of CRC T10 DIF hash.  The
correctness of the transform can be checked with the command
	modprobe tcrypt mode=47
The speed of the transform can be evaluated with the command
	modprobe tcrypt mode=320

Set the cpu frequency to constant and turn turbo off when running the
speed test so the frequency governor will not tweak the frequency and
affects the measurements.

Jussi Kivilinna 69d3150cfc crypto: ctr - make rfc3686 asynchronous block cipher
Some hardware crypto drivers register asynchronous ctr(aes), which is left
unused in IPSEC because rfc3686 template only supports synchronous block
ciphers. Some other drivers register rfc3686(ctr(aes)) to workaround this
limitation but not all.

This patch changes rfc3686 to use asynchronous block ciphers, to allow async
ctr(aes) algorithms to be utilized automatically by IPSEC.

Suresh Siddha b6f3fefe1f crypto, tcrypt: remove local_bh_disable/enable() around local_irq_disable/enable()
Ran into this while looking at some new crypto code using FPU
hitting a WARN_ON_ONCE(!irq_fpu_usable()) in the kernel_fpu_begin()
on a x86 kernel that uses the new eagerfpu model. In short, current eagerfpu
changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt()
thinks it is in the interrupt context because of the local_bh_disable().
Thus resulting in the WARN_ON().

Remove the local_bh_disable/enable() calls around the existing
local_irq_disable/enable() calls. local_irq_disable/enable() already
disables the BH.

 [ If there are any other legitimate users calling kernel_fpu_begin() from
   the process context but with BH disabled, then we can look into fixing the
   irq_fpu_usable() in future. ]

Johannes Goetzfried 107778b592 crypto: twofish - add x86_64/avx assembler implementation
This patch adds a x86_64/avx assembler implementation of the Twofish block
cipher. The implementation processes eight blocks in parallel (two 4 block
chunk AVX operations). The table-lookups are done in general-purpose registers.
For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way
module are called. A good performance increase is provided for blocksizes
greater or equal to 128B.

Patch has been tested with tcrypt and automated filesystem tests.

Tcrypt benchmark results:
