commit 5fc194ea6d34dfad9833d3043ce41d6c52aff39a upstream.
Add missing break statement in order to prevent the code from falling
through to case CRYPTO_ALG_TYPE_AHASH.

commit 7ede4c36cf7c6516986ee9d75b197c8bf73ea96f upstream.
For decrypt, req->cryptlen includes the size of the authentication
part while all functions of the driver expect cryptlen to be
the size of the encrypted data.
As it is not expected to change req->cryptlen, this patch
implements local calculation of cryptlen.

commit ee483d32ee1a1a7f7d7e918fbc350c790a5af64a upstream.
When data size is not a multiple of the alg's block size,
the SEC generates an error interrupt and dumps the registers.
And for NULL size, the SEC does just nothing and the interrupt
is awaited forever.
This patch ensures the data size is correct before submitting
the request to the SEC engine.

[ Upstream commit c9cca7034b34a2d82e9a03b757de2485c294851c ]
The MPC885 reference manual states:
SEC Lite-initiated 8xx writes can occur only on 32-bit-word boundaries, but
reads can occur on any byte boundary. Writing back a header read from a
non-32-bit-word boundary will yield unpredictable results.
In order to ensure that, cra_alignmask is set to 3 for SEC1.

[ Upstream commit eae55a586c3c8b50982bad3c3426e9c9dd7a0075 ]
The driver assumes that the ICV is as a single piece in the last
element of the scatterlist. This assumption is wrong.
This patch ensures that the ICV is properly handled regardless of
the scatterlist layout.

[ Upstream commit 3e03e792865ae48b8cfc69a0b4d65f02f467389f ]
Selftests report the following:
[ 2.984845] alg: skcipher: cbc-aes-talitos encryption test failed (wrong output IV) on test vector 0, cfg="in-place"

This above dumps show that the actual output IV is indeed the input IV.
This is due to the IV not being copied back into the request.
This patch fixes that.

commit a1a42f84011fae6ff08441a91aefeb7febc984fc upstream.
The talitos driver has two ways to perform AEAD depending on the
HW capability. Some HW support both. It is needed to give them
different names to distingish which one it is for instance when
a test fails.

commit 886a27c0fc8a34633aadb0986dba11d8c150ae2e upstream.
md5sum on some files gives wrong result
Exemple:
With the md5sum from libkcapi:
c15115c05bad51113f81bdaee735dd09 test
With the original md5sum:
bbdf41d80ba7e8b2b7be3a0772be76cb test

commit 56136631573baa537a15e0012055ffe8cfec1a33 upstream.
Today, md5sum fails with error -ENOKEY because a setkey
function is set for non hmac hashing algs, see strace output below:
mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000
accept(3, 0, NULL) = 7
vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144
splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available)
write(2, "Generation of hash for file kcap"..., 50) = 50
munmap(0x77f50000, 378880) = 0
This patch ensures that setkey() function is set only
for hmac hashing.

commit 03d2c5114c95797c0aa7d9f463348b171a274fd4 upstream.
An updated patch that also handles the additional key length requirements
for the AEAD algorithms.
The max keysize is not 96. For SHA384/512 it's 128, and for the AEAD
algorithms it's longer still. Extend the max keysize for the
AEAD size for AES256 + HMAC(SHA512).

SEC1 doesn't have IPSEC_ESP descriptor type but it is able to perform
IPSEC using HMAC_SNOOP_NO_AFEU, which is also existing on SEC2
In order to be able to define descriptors templates for SEC1 without
breaking SEC2+, we have to give lower priority to HMAC_SNOOP_NO_AFEU
so that SEC2+ selects IPSEC_ESP and not HMAC_SNOOP_NO_AFEU which is
less performant.
This is done by adding a priority field in the template. If the field
is 0, we use the default priority, otherwise we used the one in the
field.

This patchs enhances the IPSEC_ESP related functions for them to
also supports the same operations with descriptor type
HMAC_SNOOP_NO_AFEU.
The differences between the two descriptor types are:
* pointeurs 2 and 3 are swaped (Confidentiality key and
Primary EU Context IN)
* HMAC_SNOOP_NO_AFEU has CICV out in pointer 6
* HMAC_SNOOP_NO_AFEU has no primary EU context out so we get it
from the end of data out

In preparation of IPSEC for SEC1, first step is to make the mapping
helpers more generic so that they can also be used by AEAD functions.
First, the functions are moved before IPSEC functions in talitos.c
talitos_sg_unmap() and unmap_sg_talitos_ptr() are merged as they
are quite similar, the second one handling the SEC1 case an calling
the first one for SEC2
map_sg_in_talitos_ptr() and map_sg_out_talitos_ptr() are merged
into talitos_sg_map() and enhenced to support offseted zones
as used for AEAD. The actual mapping is now performed outside that
helper. The DMA sync is also done outside to not make it several
times.
talitos_edesc_alloc() size calculation are fixed to also take into
account AEAD specific parts also for SEC1

The probe error path for this driver, for all intents and purposes,
is the talitos_remove() function due to the common "goto err_out".
Without this patch applied, talitos_remove() will panic under these
two conditions:
1. If the RNG device hasn't been registered via
talitos_register_rng() prior to entry into talitos_remove(),
then the attempt to unregister the RNG "device" will cause a panic.
2. If the priv->chan array has not been allocated prior to entry
into talitos_remove(), then the per-channel FIFO cleanup will panic
because of the dereference of that NULL "array".
Both of the above scenarios occur if talitos_probe_irq() fails.
This patch resolves issue #1 by introducing a boolean to mask the
hwrng_unregister() call in talitos_unregister_rng() if RNG device
registration was unsuccessful.
It resolves issue #2 by checking that priv->chan is not NULL in the
per-channel FIFO cleanup for loop.
