eeedb61837 crypto: caam - Remove broken arc4 support
The arc4 algorithm requires storing state in the request context
in order to allow more than one encrypt/decrypt operation.  As this
driver does not seem to do that, it means that using it for more
than one operation is broken.

3cfa435c69 crypto: ux500/hash - Add namespacing to hash_init()
A recent change to the Regulator consumer API (which this driver
utilises) add prototypes for the some suspend functions.  These
functions require including header file include/linux/suspend.h.

The following tree of includes affecting this driver will be
present:

   In file included from include/linux/elevator.h:6,
                    from include/linux/blkdev.h:288,
                    from include/linux/blk-cgroup.h:23,
                    from include/linux/writeback.h:14,
                    from include/linux/memcontrol.h:22,
                    from include/linux/swap.h:9,
                    from include/linux/suspend.h:5,
                    from include/linux/regulator/consumer.h:35,
                    from drivers/crypto/ux500/hash/hash_core.c:28:

include/linux/elevator.h pulls in include/linux/hashtable.h which
contains its own version of hash_init().  This confuses the build
system and results in the following error (amongst others):

 drivers/crypto/ux500/hash/hash_core.c:1362:19: error: passing argument 1 of '__hash_init' from incompatible pointer type [-Werror=incompatible-pointer-types]
 1362 |  return hash_init(req);

Fix this by namespacing the local hash_init() such that the
source of confusion is removed.

Some of these are just trivial type changes.

8a302808c6 crypto: ccp - Fix use of merged scatterlists
Running the crypto manager self tests with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors
when using the ccp-crypto driver:

alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ...

alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ...

alg: ahash: sha224-ccp test failed (wrong result) on test vector ...

These errors are the result of improper processing of scatterlists mapped
for DMA.

Given a scatterlist in which entries are merged as part of mapping the
scatterlist for DMA, the DMA length of a merged entry will reflect the
combined length of the entries that were merged. The subsequent
scatterlist entry will contain DMA information for the scatterlist entry
after the last merged entry, but the non-DMA information will be that of
the first merged entry.

The ccp driver does not take this scatterlist merging into account. To
address this, add a second scatterlist pointer to track the current
position in the DMA mapped representation of the scatterlist. Both the DMA
representation and the original representation of the scatterlist must be
tracked as while most of the driver can use just the DMA representation,
scatterlist_map_and_copy() must use the original representation and
expects the scatterlist pointer to be accurate to the original
representation.

In order to properly walk the original scatterlist, the scatterlist must
be walked until the combined lengths of the entries seen is equal to the
DMA length of the current entry being processed in the DMA mapped
representation.

df12ef60c8 crypto: qce/sha - Do not modify scatterlist passed along with request
Crypto test driver's test_ahash_speed calls crypto_ahash_update and
crypto_ahash_final APIs repeatedly for all the available test vector
buffer lengths.

if we mark the end for scatterlist based on the current vector size then
the subsequent vectors might fail if the later buffer lengths are higher.

To avoid this, in qce do not mark the end of scatterlist in update API,
the qce_ahash_async_req_handle API already takes care of this copying
right amount of buffer from the request scatter list.

crypto testmgr deliberately corrupts the request context while passing
vectors to the import. This is to make sure that drivers do not rely on
request but they take all the necessary input from io vec passed to it.

qce casts the request context from request parameter, since it is corrupted
the sub squent hash request fails and qce hangs.

To avoid this re-initialize request context on import. The qce import
API alreasy takes care of taking the input vectors from passed io vec.

7f94adf218 crypto: hisilicon - allow smaller reads in debugfs
Originally this code rejected any read less than 256 bytes.  There
is no need for this artificial limit.  We should just use the normal
helper functions to read a string from the kernel.

1f5b07f5dd crypto: marvell/octeontx - Fix a potential NULL dereference
Smatch reports that:

    drivers/crypto/marvell/octeontx/otx_cptvf_algs.c:132 otx_cpt_aead_callback()
    warn: variable dereferenced before check 'cpt_info' (see line 121)

This function is called from process_pending_queue() as:

drivers/crypto/marvell/octeontx/otx_cptvf_reqmgr.c
   599                  /*
   600                   * Call callback after current pending entry has been
   601                   * processed, we don't do it if the callback pointer is
   602                   * invalid.
   603                   */
   604                  if (callback)
   605                          callback(res_code, areq, cpt_info);

It does appear to me that "cpt_info" can be NULL so this could lead to
a NULL dereference.

The function hisi_acc_create_sg_pool may allocate a block of
memory of size PAGE_SIZE * 2^(MAX_ORDER - 1).  This value may
exceed 2^31 on ia64, which would overflow the u32.

This patch caps it at 2^31.

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
