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.

8155330aad lib: memzero_explicit: add comment for its usage
Lets improve the comment to add a note on when to use memzero_explicit()
for those not digging through the git logs. We don't want people to
pollute places with memzero_explicit() where it's not really necessary.

ad511e260a crypto: qat - Fix incorrect uses of memzero_explicit
memzero_explicit should only be used on stack variables that get
zapped just before they go out of scope.

This patch replaces all unnecessary uses of memzero_explicit with
memset, removes two memzero_explicit calls altogether as the tfm
context comes pre-zeroed, and adds a missing memzero_explicit of
the stack variable buff in qat_alg_do_precomputes.  The memzeros
on ipad/opad + digest_size/auth_keylen are also removed as the
entire auth_state is already zeroed on entry.

5afdfd22e6 crypto: algif_rng - add random number generator support
This patch adds the random number generator support for AF_ALG.

A random number generator's purpose is to generate data without
requiring the caller to provide any data. Therefore, the AF_ALG
interface handler for RNGs only implements a callback handler for
recvmsg.

The following parameters provided with a recvmsg are processed by the
RNG callback handler:

	* sock - to resolve the RNG context data structure accessing the
	  RNG instance private to the socket

	* len - this parameter allows userspace callers to specify how
	  many random bytes the RNG shall produce and return. As the
	  kernel context for the RNG allocates a buffer of 128 bytes to
	  store random numbers before copying them to userspace, the len
	  parameter is checked that it is not larger than 128. If a
	  caller wants more random numbers, a new request for recvmsg
	  shall be made.

The size of 128 bytes is chose because of the following considerations:

	* to increase the memory footprint of the kernel too much (note,
	  that would be 128 bytes per open socket)

	* 128 is divisible by any typical cryptographic block size an
	  RNG may have

	* A request for random numbers typically only shall supply small
	  amount of data like for keys or IVs that should only require
	  one invocation of the recvmsg function.

Note, during instantiation of the RNG, the code checks whether the RNG
implementation requires seeding. If so, the RNG is seeded with output
from get_random_bytes.

A fully working example using all aspects of the RNG interface is
provided at http://www.chronox.de/libkcapi.html

ac3a497f13 hwrng: core - Do not register device opportunistically
Currently we only register the device when a valid RNG is added.
However the way it's done is buggy because we test whether there
is a current RNG to determine whether we need to register.  As
the current RNG may be missing due to a reinitialisation error
this can lead to a reregistration of the device.

As the device already has to handle a NULL current RNG anyway,
let's just register the device always and remove the complexity.

3a2c0ba5ad hwrng: use reference counts on each struct hwrng.
current_rng holds one reference, and we bump it every time we want
to do a read from it.

This means we only hold the rng_mutex to grab or drop a reference,
so accessing /sys/devices/virtual/misc/hw_random/rng_current doesn't
block on read of /dev/hwrng.

Using a kref is overkill (we're always under the rng_mutex), but
a standard pattern.

This also solves the problem that the hwrng_fillfn thread was
accessing current_rng without a lock, which could change (eg. to NULL)
underneath it.

9372b35e11 hwrng: place mutex around read functions and buffers.
There's currently a big lock around everything, and it means that we
can't query sysfs (eg /sys/devices/virtual/misc/hw_random/rng_current)
while the rng is reading.  This is a real problem when the rng is slow,
or blocked (eg. virtio_rng with qemu's default /dev/random backend)

This doesn't help (it leaves the current lock untouched), just adds a
lock to protect the read function and the static buffers, in preparation
for transition.

905b42e559 crypto: drbg - panic on continuous self test error
This patch adds a panic if the FIPS 140-2 self test error failed.
Note, that entire code is only executed with fips_enabled (i.e. when the
kernel is booted with fips=1. It is therefore not executed for 99.9% of
all user base.

As mathematically such failure cannot occur, this panic should never be
triggered. But to comply with NISTs current requirements, an endless
loop must be replaced with the panic.

When the new version of FIPS 140 will be released, this entire
continuous self test function will be ripped out as it will not be
needed any more.

This patch is functionally equivalent as implemented in ansi_cprng.c and drivers/char/random.c.

7e77bdebff crypto: af_alg - fix backlog handling
If a request is backlogged, it's complete() handler will get called
twice: once with -EINPROGRESS, and once with the final error code.

af_alg's complete handler, unlike other users, does not handle the
-EINPROGRESS but instead always completes the completion that recvmsg()
is waiting on.  This can lead to a return to user space while the
request is still pending in the driver.  If userspace closes the sockets
before the requests are handled by the driver, this will lead to
use-after-frees (and potential crashes) in the kernel due to the tfm
having been freed.

The crashes can be easily reproduced (for example) by reducing the max
queue length in cryptod.c and running the following (from
http://www.chronox.de/libkcapi.html) on AES-NI capable hardware:

 $ while true; do kcapi -x 1 -e -c '__ecb-aes-aesni' \
    -k 00000000000000000000000000000000 \

bfc7249cc2 Please consider pulling the clk framework changes toward 3.19. It is
much later than usual due to several last minute bugs that had to be
 addressed. As usual the majority of changes are new drivers and
 modifications to existing drivers. The core recieved many fixes along
 with the groundwork for several large changes coming in the future which
 will better parition clock providers from clock consumers.

5d6a546886 CONFIG_PM_RUNTIME elimination for 3.19-rc1
This removes the last few uses of CONFIG_PM_RUNTIME introduced
 recently and makes that config option finally go away.
 
 CONFIG_PM will be available directly from the menu now and
 also it will be selected automatically if CONFIG_SUSPEND or
 CONFIG_HIBERNATION is set.
