Two "ecb(des)" decryption test vectors don't exactly match any of the
encryption test vectors with input and result swapped. In preparation
for removing the decryption test vectors, add these to the encryption
test vectors, so we don't lose any test coverage.

crc32c has an unkeyed test vector but crc32 did not. Add the crc32c one
(which uses an empty input) to crc32 too, and also add a new one to both
that uses a nonempty input. These test vectors verify that crc32 and
crc32c implementations use the correct default initial state.

The Blackfin CRC driver was removed by commit 9678a8dc53c1 ("crypto:
bfin_crc - remove blackfin CRC driver"), but it was forgotten to remove
the corresponding "hmac(crc32)" test vectors. I see no point in keeping
them since nothing else appears to implement or use "hmac(crc32)", which
isn't an algorithm that makes sense anyway because HMAC is meant to be
used with a cryptographically secure hash function, which CRC's are not.
Thus, remove the unneeded test vectors.

Adds zstd support to crypto and scompress. Only supports the default
level.
Previously we held off on this patch, since there weren't any users.
Now zram is ready for zstd support, but depends on CONFIG_CRYPTO_ZSTD,
which isn't defined until this patch is in. I also see a patch adding
zstd to pstore [0], which depends on crypto zstd.

The inputs were borrowed from the AES-XTS test vectors, with key lengths

Add a generic implementation of Speck, including the Speck128 and
Speck64 variants. Speck is a lightweight block cipher that can be much
faster than AES on processors that don't have AES instructions.
We are planning to offer Speck-XTS (probably Speck128/256-XTS) as an
option for dm-crypt and fscrypt on Android, for low-end mobile devices
with older CPUs such as ARMv7 which don't have the Cryptography
Extensions. Currently, such devices are unencrypted because AES is not
fast enough, even when the NEON bit-sliced implementation of AES is
used. Other AES alternatives such as Twofish, Threefish, Camellia,
CAST6, and Serpent aren't fast enough either; it seems that only a
modern ARX cipher can provide sufficient performance on these devices.
This is a replacement for our original proposal
(https://patchwork.kernel.org/patch/10101451/) which was to offer
ChaCha20 for these devices. However, the use of a stream cipher for
disk/file encryption with no space to store nonces would have been much
more insecure than we thought initially, given that it would be used on
top of flash storage as well as potentially on top of F2FS, neither of
which is guaranteed to overwrite data in-place.
Speck has been somewhat controversial due to its origin. Nevertheless,
it has a straightforward design (it's an ARX cipher), and it appears to
be the leading software-optimized lightweight block cipher currently,
with the most cryptanalysis. It's also easy to implement without side
channels, unlike AES. Moreover, we only intend Speck to be used when
the status quo is no encryption, due to AES not being fast enough.
We've also considered a novel length-preserving encryption mode based on
ChaCha20 and Poly1305. While theoretically attractive, such a mode
would be a brand new crypto construction and would be more complicated
and difficult to implement efficiently in comparison to Speck-XTS.
There is confusion about the byte and word orders of Speck, since the
original paper doesn't specify them. But we have implemented it using
the orders the authors recommended in a correspondence with them. The
test vectors are taken from the original paper but were mapped to byte
arrays using the recommended byte and word orders.

The RSA private key for the first form should have
version, prime1, prime2, exponent1, exponent2, coefficient
values 0.
With non-zero values for prime1,2, exponent 1,2 and coefficient
the Intel QAT driver will assume that values are provided for the
private key second form. This will result in signature verification
failures for modules where QAT device is present and the modules
are signed with rsa,sha256.

The test considers a party that already has a private-public
key pair and a party that provides a NULL key. The kernel will
generate the private-public key pair for the latter, computes
the shared secret on both ends and verifies if it's the same.

This always happens on the same IV which is less than 16 bytes.
Per Ard,
"CCM IVs are 16 bytes, but due to the way they are constructed
internally, the final couple of bytes of input IV are dont-cares.
Apparently, we do read all 16 bytes, which triggers the KASAN errors."
Fix this by padding the IV with null bytes to be at least 16 bytes.

When working on AES in CCM mode for ARM, my code passed the internal
tcrypt test before I had even bothered to implement the AES-192 and
AES-256 code paths, which is strange because the tcrypt does contain
AES-192 and AES-256 test vectors for CCM.
As it turned out, the define AES_CCM_ENC_TEST_VECTORS was out of sync
with the actual number of test vectors, causing only the AES-128 ones
to be executed.
So get rid of the defines, and wrap the test vector references in a
macro that calculates the number of vectors automatically.
The following test vector counts were out of sync with the respective
defines:
BF_CTR_ENC_TEST_VECTORS 2 -> 3
BF_CTR_DEC_TEST_VECTORS 2 -> 3
TF_CTR_ENC_TEST_VECTORS 2 -> 3
TF_CTR_DEC_TEST_VECTORS 2 -> 3
SERPENT_CTR_ENC_TEST_VECTORS 2 -> 3
SERPENT_CTR_DEC_TEST_VECTORS 2 -> 3
AES_CCM_ENC_TEST_VECTORS 8 -> 14
AES_CCM_DEC_TEST_VECTORS 7 -> 17
AES_CCM_4309_ENC_TEST_VECTORS 7 -> 23
AES_CCM_4309_DEC_TEST_VECTORS 10 -> 23

In FIPS mode, additional restrictions may apply. If these restrictions
are violated, the kernel will panic(). This patch allows test vectors
for symmetric ciphers to be marked as to be skipped in FIPS mode.
Together with the patch, the XTS test vectors where the AES key is
identical to the tweak key is disabled in FIPS mode. This test vector
violates the FIPS requirement that both keys must be different.
