Subject: [PATCH v3 00/14] crypto: caam - fixes for kernel v5.3

The series solves:
- the failures found with fuzz testing;
- resources clean-up on caampkc/caamrng exit path.

The first 10 patches solve the issues found with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled.
They modify the drivers to provide a valid error (and not the hardware
error ID) to the user, via completion callbacks.
They check key length, assoclen, authsize and input size to solve the
fuzz tests that expect -EINVAL to be returned when these values are
not valid.

The next 4 patches check the algorithm registration for caampkc
module and unregister it only if the registration was successful.
Also, on caampkc/caamrng, the exit point function is executed only if the
registration was successful to avoid double freeing of resources in case
the initialization function failed.

This patch depends on series:
https://patchwork.kernel.org/project/linux-crypto/list/?series=150651

Changes since v2:
- use helper functions from crypto API, to validate the inputs;
- update rfc4106 shared descriptor with the erratum workaround;
- fix MDHA key derivation for CAAM with era < 6;
- remove check for keylen < 4, since is included in check_aes_keylen.

Horia Geantă (5):
  crypto: caam/qi - fix error handling in ERN handler
  crypto: caam - fix return code in completion callbacks
  crypto: caam - update IV only when crypto operation succeeds
  crypto: caam - keep both virtual and dma key addresses
  crypto: caam - fix MDHA key derivation for certain user key lengths

Iuliana Prodan (9):
  crypto: caam - check key length
  crypto: caam - check authsize
  crypto: caam - check assoclen
  crypto: caam - check zero-length input
  crypto: caam - update rfc4106 sh desc to support zero length input
  crypto: caam - free resources in case caam_rng registration failed
  crypto: caam - execute module exit point only if necessary
  crypto: caam - unregister algorithm only if the registration succeeded
  crypto: caam - change return value in case CAAM has no MDHA
