The CTR DRBG derives its random data from the CTR that is encrypted with
AES.
This patch now changes the CTR DRBG implementation such that the
CTR AES mode is employed. This allows the use of steamlined CTR AES
implementation such as ctr-aes-aesni.
Unfortunately there are the following subtile changes we need to apply
when using the CTR AES mode:
- the CTR mode increments the counter after the cipher operation, but
the CTR DRBG requires the increment before the cipher op. Hence, the
crypto_inc is applied to the counter (drbg->V) once it is
recalculated.
- the CTR mode wants to encrypt data, but the CTR DRBG is interested in
the encrypted counter only. The full CTR mode is the XOR of the
encrypted counter with the plaintext data. To access the encrypted
counter, the patch uses a NULL data vector as plaintext to be
"encrypted".

alloc_workqueue replaces deprecated create_workqueue().
The workqueue device_reset_wq has workitem &reset_data->reset_work per
adf_reset_dev_data. The workqueue pf2vf_resp_wq is a workqueue for
PF2VF responses has workitem &pf2vf_resp->pf2vf_resp_work per pf2vf_resp.
The workqueue adf_vf_stop_wq is used to call adf_dev_stop()
asynchronously.
Dedicated workqueues have been used in all cases since the workitems
on the workqueues are involved in operation of crypto which can be used in
the IO path which is depended upon during memory reclaim. Hence,
WQ_MEM_RECLAIM has been set to gurantee forward progress under memory
pressure.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.

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

mpi_read_from_buffer() and mpi_read_raw_data() do basically the same thing

The first two bytes of the input buffer encode its expected length and
mpi_read_from_buffer() prints a console message if the given buffer is too
short.
However, there are some oddities with how this message is printed:
- It is printed at the default loglevel. This is different from the
one used in the case that the first two bytes' value is unsupportedly
large, i.e. KERN_INFO.
- The format specifier '%d' is used for unsigned ints.
- It prints the values of nread and *ret_nread. This is redundant since
the former is always the latter + 1.
Clean this up as follows:
- Use pr_info() rather than printk() with no loglevel.
- Use the format specifiers '%u' in place if '%d'.
- Do not print the redundant 'nread' but the more helpful 'nbytes' value.

Currently, if the input buffer is shorter than the expected length as
indicated by its first two bytes, an MPI instance of this expected length
will be allocated and filled with as much data as is available. The rest
will remain uninitialized.
Instead of leaving this condition undetected, an error code should be
reported to the caller.
Since this situation indicates that the input buffer's first two bytes,
encoding the number of expected bits, are garbled, -EINVAL is appropriate
here.
If the input buffer is shorter than indicated by its first two bytes,
make mpi_read_from_buffer() return -EINVAL.
Get rid of the 'nread' variable: with the new semantics, the total number
of bytes read from the input buffer is known in advance.

mpi_read_from_buffer() reads a MPI from a buffer into a newly allocated
MPI instance. It expects the buffer's leading two bytes to contain the
number of bits, followed by the actual payload.
On failure, it returns NULL and updates the in/out argument ret_nread
somewhat inconsistently:
- If the given buffer is too short to contain the leading two bytes
encoding the number of bits or their value is unsupported, then
ret_nread will be cleared.
- If the allocation of the resulting MPI instance fails, ret_nread is left
as is.
The only user of mpi_read_from_buffer(), digsig_verify_rsa(), simply checks
for a return value of NULL and returns -ENOMEM if that happens.
While this is all of cosmetic nature only, there is another error condition
which currently isn't detectable by the caller of mpi_read_from_buffer():
if the given buffer is too small to hold the number of bits as encoded in
its first two bytes, the return value will be non-NULL and *ret_nread > 0.
In preparation of communicating this condition to the caller, let
mpi_read_from_buffer() return error values by means of the ERR_PTR()
mechanism.
Make the sole caller of mpi_read_from_buffer(), digsig_verify_rsa(),
check the return value for IS_ERR() rather than == NULL. If IS_ERR() is
true, return the associated error value rather than the fixed -ENOMEM.

The number of bits, nbits, is calculated in mpi_read_raw_data() as follows:
nbits = nbytes * 8;
Afterwards, the number of leading zero bits of the first byte get
subtracted:
nbits -= count_leading_zeros(buffer[0]);
However, count_leading_zeros() takes an unsigned long and thus,
the u8 gets promoted to an unsigned long.
Thus, the above doesn't subtract the number of leading zeros in the most
significant nonzero input byte from nbits, but the number of leading
zeros of the most significant nonzero input byte promoted to unsigned long,
i.e. BITS_PER_LONG - 8 too many.
Fix this by subtracting
count_leading_zeros(...) - (BITS_PER_LONG - 8)
from nbits only.

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).

While reviewing the addition of io{read,write}64be accessors, Arnd
-finds a potential problem:
"If an architecture overrides readq/writeq to have barriers but does
not override ioread64be/iowrite64be, this will lack the barriers and
behave differently from the little-endian version. I think the only
affected architecture is ARC, since ARM and ARM64 both override the
big-endian accessors to have the correct barriers, and all others
don't use barriers at all."
-suggests a fix for the same problem in existing code (16/32-bit
accessors); the fix leads "to a double-swap on architectures that
don't override the io{read,write}{16,32}be accessors, but it will
work correctly on all architectures without them having to override
these accessors."

The sizeof(*ctx->dec_cd) and sizeof(*ctx->enc_cd) are equal,
but we should use the correct one for freeing memory anyway.

The CRYPTO_MSG_GETALG netlink message type provides a buffer to the
kernel to retrieve information from the kernel. The data buffer will not
provide any input and will not be read. Hence the nlmsg_parse is not
applicable to this netlink message type.
This patch fixes the following kernel log message when using this
netlink interface:
netlink: 208 bytes leftover after parsing attributes in process `XXX'.
Patch successfully tested with libkcapi from [1] which uses
CRYPTO_MSG_GETALG to obtain cipher-specific information from the kernel.

Pull SCSI fixes from James Bottomley:
"This is a set of four fixes noticed in the merge window. The aacraid
one is an optimisation, the mp3sas one fixes a spurious printk, the
sd_check_events one fixes a theoretical race and the failed zero
length commands fixes a bug in our completion/retry routines that has
been causing problems in the field"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
aacraid: do not activate events on non-SRC adapters
mpt3sas: add missing curly braces
sd: get disk reference in sd_check_events()
scsi_lib: correctly retry failed zero length REQ_TYPE_FS commands
