[PATCH 1/4] crypto: ccree: drop useless type flag during reg

[Gilad Ben-Yossef]

Drop the explicit setting of CRYPTO_ALG_TYPE_AEAD or
CRYPTO_ALG_TYPE_SKCIPHER flags during alg registration as they are
set anyway by the framework.

[PATCH 2/4] crypto: ccree: remove cipher ivgen left overs

[Gilad Ben-Yossef]

IV generation is not available via the skcipher interface.
Remove the left over support of it from the ablkcipher days.

[PATCH 3/4] crypto: ccree: zero all of request ctx before use

[Gilad Ben-Yossef]

In certain error path req_ctx->iv was being freed despite
not being allocated because it was not initialized to NULL.
Rather than play whack a mole with the structure various
field, zero it before use.

This fixes a kernel panic that may occur if an invalid
buffer size was requested triggering the bug above.

Fixes: 63ee04c8b491 ("crypto: ccree - add skcipher support")

[PATCH 4/4] crypto: ccree: allow bigger than sector XTS op

[Gilad Ben-Yossef]

The ccree driver had a sanity check that we are not asked
to encrypt an XTS buffer bigger than a sane sector size
since XTS IV needs to include the sector number in the IV
so this is not expected in any real use case.

Unfortunately, this breaks cryptsetup benchmark test which
has a synthetic performance test using 64k buffer of data
with the same IV.

Remove the sanity check and allow the user to hang themselves
and/or run benchmarks if they so wish.
