Horia Geantă b66ad0b7aa crypto: tcrypt - remove AES-XTS-192 speed tests
Remove xts(aes) speed tests with 2 x 192-bit keys, since implementations
adhering strictly to IEEE 1619-2007 standard cannot cope with key sizes
other than 2 x 128, 2 x 256 bits - i.e. AES-XTS-{128,256}:

Gilad Ben-Yossef 981a2e3e45 crypto: tcrypt - don't disable irqs and wait
The tcrypt AEAD cycles speed tests disables irqs during the test, which is
broken at the very least since commit
'1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")'
adds a wait for completion as part of the test and probably since
switching to the new AEAD API.

While the result of taking a cycle count diff may not mean much on SMP
systems if the task migrates, it's good enough for tcrypt being the quick
& dirty dev tool it is. It's also what all the other (i.e. hash) cycle
speed tests do.

Rabin Vincent 76512f2d8c crypto: tcrypt - Add debug prints
tcrypt is very tight-lipped when it succeeds, but a bit more feedback
would be useful when developing or debugging crypto drivers, especially
since even a successful run ends with the module failing to insert. Add
a couple of debug prints, which can be enabled with dynamic debug:

Before:

 # insmod tcrypt.ko mode=10
 insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable

After:

 # insmod tcrypt.ko mode=10 dyndbg

Herbert Xu 72259deb3a crypto: tcrypt - Fix memory leaks/crashes in multibuffer hash speed test
This patch resolves a number of issues with the mb speed test
function:

* The tfm is never freed.
* Memory is allocated even when we're not using mb.
* When an error occurs we don't wait for completion for other requests.
* When an error occurs during allocation we may leak memory.
* The test function ignores plen but still runs for plen != blen.
* The backlog flag is incorrectly used (may crash).

This patch tries to resolve all these issues as well as making
the code consistent with the existing hash speed testing function.

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.

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.

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.
