Since 6de62f15b5 ("crypto: algif_hash - Require setkey before
accept(2)"), the AF_ALG interface requires userspace to provide a key
to any algorithm that has a setkey method. However, the non-HMAC
algorithms are not keyed, so setting a key is unnecessary.
Fix this by removing the setkey method from the non-keyed hash
algorithms.

To be able to generate shared descriptors for AEAD, the authentication size
needs to be known. However, there is no imposed order of calling .setkey,
.setauthsize callbacks.
Thus, in case authentication size is not known at .setkey time, defer it
until .setauthsize is called.
The authsize != 0 check was incorrectly removed when converting the driver

There are a few things missed by the conversion to the
new AEAD interface:
1 - echainiv(authenc) encrypt shared descriptor
The shared descriptor is incorrect: due to the order of operations,
at some point in time MATH3 register is being overwritten.
2 - buffer used for echainiv(authenc) encrypt shared descriptor
Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
exclusive and thus use the same buffer in context state: sh_desc_enc.
However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
leading to errors when echainiv(authenc(...)) algorithms are used:
DECO: desc idx 14: Header Error. Invalid length or parity, or
certain other problems.
While here, also fix a typo: dma_mapping_error() is checking
for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

There are SoCs like LS1043A where CAAM endianness (BE) does not match
the default endianness of the core (LE).
Moreover, there are requirements for the driver to handle cases like
CPU_BIG_ENDIAN=y on ARM-based SoCs.
This requires for a complete rewrite of the I/O accessors.
PPC-specific accessors - {in,out}_{le,be}XX - are replaced with
generic ones - io{read,write}[be]XX.
Endianness is detected dynamically (at runtime) to allow for
multiplatform kernels, for e.g. running the same kernel image
on LS1043A (BE CAAM) and LS2080A (LE CAAM) armv8-based SoCs.
While here: debugfs entries need to take into consideration the
endianness of the core when displaying data. Add the necessary
glue code so the entries remain the same, but they are properly
read, regardless of the core and/or SEC endianness.
Note: pdb.h fixes only what is currently being used (IPsec).

Most users of IS_ERR_VALUE() in the kernel are wrong, as they
pass an 'int' into a function that takes an 'unsigned long'
argument. This happens to work because the type is sign-extended
on 64-bit architectures before it gets converted into an
unsigned type.
However, anything that passes an 'unsigned short' or 'unsigned int'
argument into IS_ERR_VALUE() is guaranteed to be broken, as are
8-bit integers and types that are wider than 'unsigned long'.
Andrzej Hajda has already fixed a lot of the worst abusers that
were causing actual bugs, but it would be nice to prevent any
users that are not passing 'unsigned long' arguments.
This patch changes all users of IS_ERR_VALUE() that I could find
on 32-bit ARM randconfig builds and x86 allmodconfig. For the
moment, this doesn't change the definition of IS_ERR_VALUE()
because there are probably still architecture specific users
elsewhere.
Almost all the warnings I got are for files that are better off
using 'if (err)' or 'if (err < 0)'.
The only legitimate user I could find that we get a warning for
is the (32-bit only) freescale fman driver, so I did not remove
the IS_ERR_VALUE() there but changed the type to 'unsigned long'.
For 9pfs, I just worked around one user whose calling conventions
are so obscure that I did not dare change the behavior.
I was using this definition for testing:
#define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \
unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO))
which ends up making all 16-bit or wider types work correctly with
the most plausible interpretation of what IS_ERR_VALUE() was supposed
to return according to its users, but also causes a compile-time
warning for any users that do not pass an 'unsigned long' argument.
I suggested this approach earlier this year, but back then we ended
up deciding to just fix the users that are obviously broken. After
the initial warning that caused me to get involved in the discussion
(fs/gfs2/dir.c) showed up again in the mainline kernel, Linus
asked me to send the whole thing again.

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.

caam does not properly calculate the size of the retained state
when non-block aligned hashes are requested - it uses the wrong
buffer sizes, which results in errors such as:
caam_jr 2102000.jr1: 40000501: DECO: desc idx 5: SGT Length Error. The descriptor is trying to read more data than is contained in the SGT table.
We end up here with:
in_len 0x46 blocksize 0x40 last_bufsize 0x0 next_bufsize 0x6
to_hash 0x40 ctx_len 0x28 nbytes 0x20
which results in a job descriptor of:
jobdesc@889: ed03d918: b0861c08 3daa0080 f1400000 3d03d938
jobdesc@889: ed03d928: 00000068 f8400000 3cde2a40 00000028
where the word at 0xed03d928 is the expected data size (0x68), and a
scatterlist containing:
sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
sg@892: ed03d948: 00000000 3d03d100 00000006 00000000
sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000
0x68 comes from 0x28 (the context size) plus the "in_len" rounded down
to a block size (0x40). in_len comes from 0x26 bytes of unhashed data
from the previous operation, plus the 0x20 bytes from the latest
operation.
The fixed version would create:
sg@892: ed03d938: 00000000 3cde2a40 00000028 00000000
sg@892: ed03d948: 00000000 3d03d100 00000026 00000000
sg@892: ed03d958: 00000000 7e8aa700 40000020 00000000
which replaces the 0x06 length with the correct 0x26 bytes of previously
unhashed data.
This fixes a previous commit which erroneously "fixed" this due to a
DMA-API bug report; that commit indicates that the bug was caused via a
test_ahash_pnum() function in the tcrypt module. No such function has
ever existed in the mainline kernel. Given that the change in this
commit has been tested with DMA API debug enabled and shows no issue,
I can only conclude that test_ahash_pnum() was triggering that bad
behaviour by CAAM.

Most significant part of JQCR (Job Queue Control Register) contains

DWS - Double Word Swap.
The bits are automatically set by the Job Queue Controller HW.
Unfortunately these bits are cleared in SW when submitting descriptors
via the register-based service interface.
>From LS1021A:
JQCR_MS = 08080100 - before writing: ILE | DWS | SRC (JR0)
JQCR_MS = 30000100 - after writing: WHL | FOUR | SRC (JR0)

LS1021A is a QorIQ SoC having little endian CAAM.
There are a few differences b/w QorIQ and i.MX from CAAM perspective:
1. i.MX platforms are somewhat special wrt. 64-bit registers:
-big endian format at 64-bit level: MSW at address+0 and LSW at address+4
-little endian format at 32-bit level (within MSW and LSW)
and thus need special handling.
2. No CCM (clock controller module) for QorIQ.
No CAAM clocks to enable / disable.
A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate
CAAM is little endian (*). It is hidden from the user (to avoid
misconfiguration); when adding support for a new platform with LE CAAM,
either the Kconfig needs to be updated or the corresponding defconfig
needs to indicate that CAAM is LE.
(*) Using a DT property to provide CAAM endianness would not allow
for the ifdeffery.
In order to keep changes to a minimum, the following changes
are postponed:
-endianness fix of the last word in the S/G (rsvd2, bpid, offset),
fields are always 0 anyway;
-S/G format fix for i.MX7 (yes, i.MX7 support was not added yet,
