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.

c61e5644c6 crypto: hisilicon - Cap block size at 2^31
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/'

The src/dst length is not aligned with AES_BLOCK_SIZE(which is 16) in some
testcases in tcrypto.ko.

For example, the src/dst length of one of cts(cbc(aes))'s testcase is 17, the

case and get a wrong at then end.

  (pp: plaintext  cc:ciphertext)

Fix this issue by limit the length of dest buffer.

8c855f0720 crypto: virtio: Fix use-after-free in virtio_crypto_skcipher_finalize_req()
The system'll crash when the users insmod crypto/tcrypto.ko with mode=155
( testing "authenc(hmac(sha1),cbc(aes))" ). It's caused by reuse the memory
of request structure.

In crypto_authenc_init_tfm(), the reqsize is set to:
  [PART 1] sizeof(authenc_request_ctx) +
  [PART 2] ictx->reqoff +
  [PART 3] MAX(ahash part, skcipher part)
and the 'PART 3' is used by both ahash and skcipher in turn.

When the virtio_crypto driver finish skcipher req, it'll call ->complete
callback(in crypto_finalize_skcipher_request) and then free its
resources whose pointers are recorded in 'skcipher parts'.

However, the ->complete is 'crypto_authenc_encrypt_done' in this case,
it will use the 'ahash part' of the request and change its content,
so virtio_crypto driver will get the wrong pointer after ->complete
finish and mistakenly free some other's memory. So the system will crash
when these memory will be used again.

The resources which need to be cleaned up are not used any more. But the
pointers of these resources may be changed in the function
"crypto_finalize_skcipher_request". Thus release specific resources before
calling this function.

f3b140ad85 Crypto/chcr: Fixes compilations warnings
This patch fixes the compilation warnings displayed by sparse tool for
chcr driver.

V1->V2

Avoid type casting by using get_unaligned_be32() and
put_unaligned_be16/32() functions.

The key which comes from stack is an u8 byte stream so we store it in
an unsigned char array(ablkctx->key). The function get_aes_decrypt_key()
is a used to calculate  the reverse round key for decryption, for this
operation the key has to be divided into 4 bytes, so to extract 4 bytes
from an u8 byte stream and store it in an u32 variable, get_aligned_be32()
is used. Similarly for copying back the key from u32 variable to the
original u8 key stream, put_aligned_be32() is used.

1806c13dc2 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
xdp_umem.c had overlapping changes between the 64-bit math fix
for the calculation of npgs and the removal of the zerocopy
memory type which got rid of the chunk_size_nohdr member.

The mlx5 Kconfig conflict is a case where we just take the
net-next copy of the Kconfig entry dependency as it takes on
the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

835ae3bb53 drivers/crypto/ccp/sev-dev.c: get rid of pointless access_ok()
Contrary to the comments, those do *NOT* verify anything about
writability of memory, etc.

In all cases addresses are passed only to copy_to_user().

In order to be compatible with devices of different versions, V1 in the

7795c0baf5 crypto: stm32/crc32 - protect from concurrent accesses
Protect STM32 CRC device from concurrent accesses.

As we create a spinlocked section that increase with buffer size,
we provide a module parameter to release the pressure by splitting
critical section in chunks.

Size of each chunk is defined in burst_size module parameter.
By default burst_size=0, i.e. don't split incoming buffer.
