Zhou Wang 700f7d0d29 crypto: hisilicon - fix to return sub-optimal device when best device has no qps
Currently find_zip_device() finds zip device which has the min NUMA
distance with current CPU.

This patch modifies find_zip_device to return sub-optimal device when best
device has no qps. This patch sorts all devices by NUMA distance, then
finds the best zip device which has free qp.

Now that the blkcipher algorithm type has been removed in favor of

Eric Biggers c65058b758 crypto: skcipher - remove the "blkcipher" algorithm type
Now that all "blkcipher" algorithms have been converted to "skcipher",
remove the blkcipher algorithm type.

The skcipher (symmetric key cipher) algorithm type was introduced a few
years ago to replace both blkcipher and ablkcipher (synchronous and
asynchronous block cipher).  The advantages of skcipher include:

  - A much less confusing name, since none of these algorithm types have
    ever actually been for raw block ciphers, but rather for all
    length-preserving encryption modes including block cipher modes of
    operation, stream ciphers, and other length-preserving modes.

  - It unified blkcipher and ablkcipher into a single algorithm type
    which supports both synchronous and asynchronous implementations.
    Note, blkcipher already operated only on scatterlists, so the fact
    that skcipher does too isn't a regression in functionality.

  - Better type safety by using struct skcipher_alg, struct
    crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc.

  - It sometimes simplifies the implementations of algorithms.

Also, the blkcipher API was no longer being tested.

Eric Biggers cec0cb8a28 crypto: skcipher - remove crypto_has_ablkcipher()
crypto_has_ablkcipher() has no users, and it does the same thing as
crypto_has_skcipher() anyway.  So remove it.  This also removes the last
user of crypto_skcipher_type() and crypto_skcipher_mask(), so remove
those too.

Eric Biggers d3ca75a8b3 crypto: skcipher - unify the crypto_has_skcipher*() functions
crypto_has_skcipher() and crypto_has_skcipher2() do the same thing: they
check for the availability of an algorithm of type skcipher, blkcipher,
or ablkcipher, which also meets any non-type constraints the caller
specified.  And they have exactly the same prototype.

Therefore, eliminate the redundancy by removing crypto_has_skcipher()
and renaming crypto_has_skcipher2() to crypto_has_skcipher().

David Sterba a1afe27492 crypto: testmgr - add test vectors for blake2b
Test vectors for blake2b with various digest sizes. As the algorithm is
the same up to the digest calculation, the key and input data length is
distributed in a way that tests all combinanions of the two over the
digest sizes.

Based on the suggestion from Eric, the following input sizes are tested
[0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
padded and the non-padded input buffers are tested.

          blake2b-160  blake2b-256  blake2b-384  blake2b-512
         ---------------------------------------------------
len=0   | klen=0       klen=1       klen=32      klen=64
len=1   | klen=32      klen=64      klen=0       klen=1
len=7   | klen=64      klen=0       klen=1       klen=32
len=15  | klen=1       klen=32      klen=64      klen=0
len=64  | klen=0       klen=1       klen=32      klen=64
len=247 | klen=32      klen=64      klen=0       klen=1
len=256 | klen=64      klen=0       klen=1       klen=32

Where key:

- klen=0: empty key
- klen=1: 1 byte value 0x42, 'B'
- klen=32: first 32 bytes of the default key, sequence 00..1f
- klen=64: default key, sequence 00..3f

The unkeyed vectors are ordered before keyed, as this is required by
testmgr.

David Sterba 91d689337f crypto: blake2b - add blake2b generic implementation
The patch brings support of several BLAKE2 variants (2b with various
digest lengths).  The keyed digest is supported, using tfm->setkey call.
The in-tree user will be btrfs (for checksumming), we're going to use
the BLAKE2b-256 variant.

The code is reference implementation taken from the official sources and
modified in terms of kernel coding style (whitespace, comments, uintXX_t
-> uXX types, removed unused prototypes and #ifdefs, removed testing
code, changed secure_zero_memory -> memzero_explicit, used own helpers
for unaligned reads/writes and rotations).

Further changes removed sanity checks of key length or output size,
these values are verified in the crypto API callbacks or hardcoded in
shash_alg and not exposed to users.

Ard Biesheuvel f398243e9f crypto: ecdh - fix big endian bug in ECC library
The elliptic curve arithmetic library used by the EC-DH KPP implementation
assumes big endian byte order, and unconditionally reverses the byte
and word order of multi-limb quantities. On big endian systems, the byte
reordering is not necessary, while the word ordering needs to be retained.

So replace the __swab64() invocation with a call to be64_to_cpu() which
should do the right thing for both little and big endian builds.

ccp_tx_submit is passed a dma_async_tx_descriptor which is contained in
a ccp_dma_desc and adds it to a ccp channel's pending list:

	list_del(&desc->entry);
	list_add_tail(&desc->entry, &chan->pending);

The problem is that desc->entry may be uninitialized in the
async_trigger_callback path where the descriptor was gotten
from ccp_prep_dma_interrupt which got it from ccp_alloc_dma_desc
which doesn't initialize the desc->entry list head. So, just
initialize the list head to avoid the problem.

Hook, Gary 03f008c52b crypto: ccp - Verify access to device registers before initializing
Check early whether device registers can be accessed. Some BIOSes have
a broken security policy that prevents access to the device registers,
and return values from ioread() can be misinterpreted. If a read of
a feature register returns a -1, we may not be able to access
any device register, so report the problem and suggestion, and return.

For the PSP, the feature register is checked. For the CCP, the queue
register is checked.

Ashish Kalra 1d55fdc857 crypto: ccp - Retry SEV INIT command in case of integrity check failure.
SEV INIT command loads the SEV related persistent data from NVS
and initializes the platform context. The firmware validates the
persistent state. If validation fails, the firmware will reset
the persisent state and return an integrity check failure status.

At this point, a subsequent INIT command should succeed, so retry
the command. The INIT command retry is only done during driver
initialization.

Additional enums along with SEV_RET_SECURE_DATA_INVALID are added
to sev_ret_code to maintain continuity and relevance of enum values.
