[v2,00/14] crypto: caam - fixes for kernel v5.3

Message

Iuliana Prodan July 18, 2019, 11:57 p.m. UTC

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.
