[PATCH v6 00/11] Regression fixes/clean ups in the Qualcomm crypto engine driver

[Thara Gopinath <thara.gopinath@linaro.org>]

This patch series is a result of running kernel crypto fuzz tests (by
enabling CONFIG_CRYPTO_MANAGER_EXTRA_TESTS) on the transformations
currently supported via the Qualcomm crypto engine on sdm845.  The first
nine patches are fixes for various regressions found during testing. The
last two patches are minor clean ups of unused variable and parameters.

v5->v6:
	- Return 0 for zero length messages instead of -EOPNOTSUPP in the
	  cipher algorithms as pointed out by Eric Biggers.
	- Remove the wrong TODO in patch 6 which implied that AES CBC can
	  do partial block sizes when it is actually CTS mode that can as
	  pointed out my Eric Biggers.

v4->v5:
	- Fixed build warning/error in patch for wrong assignment of const
	  pointer as reported by kernel test robot <lkp@intel.com>.
	- Rebased to 5.11-rc6.
v3->v4:
	- Fixed the bug where only two bytes of byte_count were getting
	  saved and restored instead of all eight bytes. Thanks Bjorn for
	  catching this.
	- Split patch 3 "Fix regressions found during fuzz testing" into
	  6 patches as requested by Bjorn.
	- Dropped crypto from all subject headers.
	- Rebased to 5.11-rc5
v2->v3:
        - Made the comparison between keys to check if any two keys are
          same for triple des algorithms constant-time as per
          Nym Seddon's suggestion.
        - Rebased to 5.11-rc4.
v1->v2:
        - Introduced custom struct qce_sha_saved_state to store and restore
          partial sha transformation.
        - Rebased to 5.11-rc3.

Thara Gopinath (11):
  crypto: qce: sha: Restore/save ahash state with custom struct in
    export/import
  crypto: qce: sha: Hold back a block of data to be transferred as part
    of final
  crypto: qce: skcipher: Return unsupported if key1 and key 2 are same
    for AES XTS algorithm
  crypto: qce: skcipher: Return unsupported if any three keys are same
    for DES3 algorithms
  crypto: qce: skcipher: Return error for zero length messages
  crypto: qce: skcipher: Return error for non-blocksize data(ECB/CBC
    algorithms)
  crypto: qce: skcipher: Set ivsize to 0 for ecb(aes)
  crypto: qce: skcipher: Improve the conditions for requesting AES
    fallback cipher
  crypto: qce: common: Set data unit size to message length for AES XTS
    transformation
  crypto: qce: Remover src_tbl from qce_cipher_reqctx
  crypto: qce: Remove totallen and offset in qce_start
