commit 40c98cb57c upstream.
RNG instantiation was previously fixed by
commit 62743a4145 ("crypto: caam - fix RNG init descriptor ret. code checking")
while deinstantiation was not addressed.
Since the descriptors used are similar, in the sense that they both end
with a JUMP HALT command, checking for errors should be similar too,
i.e. status code 7000_0000h should be considered successful.

commit d128af1787 upstream.
The AEAD givenc descriptor relies on moving the IV through the
output FIFO and then back to the CTX2 for authentication. The
SEQ FIFO STORE could be scheduled before the data can be
read from OFIFO, especially since the SEQ FIFO LOAD needs
to wait for the SEQ FIFO LOAD SKIP to finish first. The
SKIP takes more time when the input is SG than when it's
a contiguous buffer. If the SEQ FIFO LOAD is not scheduled
before the STORE, the DECO will hang waiting for data
to be available in the OFIFO so it can be transferred to C2.
In order to overcome this, first force transfer of IV to C2
by starting the "cryptlen" transfer first and then starting to
store data from OFIFO to the output buffer.

commit e930c765ca upstream.
caam_jr_alloc() used to return NULL if a JR device could not be
allocated for a session. In turn, every user of this function used
IS_ERR() function to verify if anything went wrong, which does NOT look
for NULL values. This made the kernel crash if the sanity check failed,
because the driver continued to think it had allocated a valid JR dev
instance to the session and at some point it tries to do a caam_jr_free()
on a NULL JR dev pointer.

commit 79152e8d08 upstream.
The tcrypt testing module on Exynos5422-based Odroid XU3/4 board failed on
testing 8 kB size blocks:
$ sudo modprobe tcrypt sec=1 mode=500
testing speed of async ecb(aes) (ecb-aes-s5p) encryption
test 0 (128 bit key, 16 byte blocks): 21971 operations in 1 seconds (351536 bytes)

test 3 (128 bit key, 1024 byte blocks): 21685 operations in 1 seconds (22205440 bytes)
test 4 (128 bit key, 8192 byte blocks):
This was caused by a race issue of missed BRDMA_DONE ("Block cipher
Receiving DMA") interrupt. Device starts processing the data in DMA mode
immediately after setting length of DMA block: receiving (FCBRDMAL) or
transmitting (FCBTDMAL). The driver sets these lengths from interrupt
handler through s5p_set_dma_indata() function (or xxx_setdata()).
However the interrupt handler was first dealing with receive buffer
(dma-unmap old, dma-map new, set receive block length which starts the
operation), then with transmit buffer and finally was clearing pending
interrupts (FCINTPEND). Because of the time window between setting
receive buffer length and clearing pending interrupts, the operation on
receive buffer could end already and driver would miss new interrupt.
User manual for Exynos5422 confirms in example code that setting DMA
block lengths should be the last operation.
The tcrypt hang could be also observed in following blocked-task dmesg:

commit 412c98c1be upstream.
The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx)
allocated in one DMA-tagged region. While the kernel's heap allocator
should place the overall struct on a cacheline aligned boundary, the 2
buffers contained within may not necessarily align. Consenquently, the ends
of unaligned buffers may not fully flush, and if so, stale data will be left
behind, resulting in small repeating patterns.
This fix aligns the buffers inside the struct.
Note that not all of the data inside caam_rng_ctx necessarily needs to be
DMA-tagged, only the buffers themselves require this. However, a fix would
incur the expense of error-handling bloat in the case of allocation failure.

There are at least two, possibly three problems here:
a) when writing into the FIFO, we copy the pointer rather than the
actual data we want to give to the hardware
b) the data pointer is an array of 8-bit values, while the FIFO
is 32-bit wide, so both the read and write access fail to do
a proper type conversion
c) This seems incorrect for big-endian kernels, on which we need to
byte-swap any register access, but not normally FIFO accesses,
at least the DMA case doesn't do it either.
This converts the bogus loop to use the same readsl/writesl pair
that we use for the two other modes (DMA and polling). This is
more efficient and consistent, and probably correct for endianess.
The bug has existed since the driver was first merged, and was
probably never detected because nobody tried to use interrupt mode.
It might make sense to backport this fix to stable kernels, depending
on how the crypto maintainers feel about that.

Consistently use AES_KEYSIZE_128 instead of arbitrary defined value.

The AES IV length is always 128bits, just use the define from aes.h

This is actually defined in include/crypto/aes.h , no need to have
a a different symbol for the same thing twice.

As we are preparing to enable multiplatform support on EXYNOS,
we can no longer include mach/*.h or plat/*.h headers from device
drivers.
The s5p-sss driver was just enabled for EXYNOS when it used to
be used only on s5pv210, and it includes two samsung platform
specific header files for historic reasons. Fortunately, it no
longer actually needs them, so we can remove the #includes and
avoid the problem
