<title>crypto: xxhash - Implement xxhash support</title>

xxhash is currently implemented as a self-contained module in /lib.
This patch enables that module to be used as part of the generic kernel
crypto framework. It adds a simple wrapper to the 64bit version.

I've also added test vectors (with help from Nick Terrell). The upstream
xxhash code is tested by running hashing operation on random 222 byte
data with seed values of 0 and a prime number. The upstream test
suite can be found at https://github.com/Cyan4973/xxHash/blob/cf46e0c/xxhsum.c#L664

Essentially hashing is run on data of length 0,1,14,222 with the
aforementioned seed values 0 and prime 2654435761. The particular random
222 byte string was provided to me by Nick Terrell by reading
/dev/random and the checksums were calculated by the upstream xxsum
utility with the following bash script:

dd if=/dev/random of=TEST_VECTOR bs=1 count=222

for a in 0 1; do
	for l in 0 1 14 222; do
		for s in 0 2654435761; do
			echo algo $a length $l seed $s;
			head -c $l TEST_VECTOR | ~/projects/kernel/xxHash/xxhsum -H$a -s$s
		done
	done
done

This produces output as follows:

algo 0 length 0 seed 0
02cc5d05  stdin
algo 0 length 0 seed 2654435761

algo 0 length 1 seed 0

On PowerPC with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y, there is sometimes
a crash in generate_random_aead_testvec().  The problem is that the
generated test vectors use data lengths of up to about 2 * PAGE_SIZE,
which is 128 KiB on PowerPC; however, the data length fields in the test
vectors are 'unsigned short', so the lengths get truncated.  Fix this by
changing the relevant fields to 'unsigned int'.

When the extra crypto self-tests are enabled, test each skcipher
algorithm against its generic implementation when one is available.
This involves: checking the algorithm properties for consistency, then
randomly generating test vectors using the generic implementation and
running them against the implementation under test.  Both good and bad
inputs are tested.

This has already detected a bug in the skcipher_walk API, a bug in the
LRW template, and an inconsistency in the cts implementations.

<id>5283a8ee9badf699bd4a5a622011f9d4d50fecde</id>
<content type='text'>
Update testmgr to support testing for specific errors from setkey() and
digest() for hashes; setkey() and encrypt()/decrypt() for skciphers and
ciphers; and setkey(), setauthsize(), and encrypt()/decrypt() for AEADs.
This is useful because algorithms usually restrict the lengths or format
of the message, key, and/or authentication tag in some way.  And bad
inputs should be tested too, not just good inputs.

As part of this change, remove the ambiguously-named 'fail' flag and
replace it with 'setkey_error = -EINVAL' for the only test vector that
used it -- the DES weak key test vector.  Note that this tightens the
test to require -EINVAL rather than any error code, but AFAICS this
won't cause any test failure.

Other than that, these new fields aren't set on any test vectors yet.
Later patches will do so.

Update testmgr to support testing for specific errors from setkey() and
digest() for hashes; setkey() and encrypt()/decrypt() for skciphers and
ciphers; and setkey(), setauthsize(), and encrypt()/decrypt() for AEADs.
This is useful because algorithms usually restrict the lengths or format
of the message, key, and/or authentication tag in some way.  And bad
inputs should be tested too, not just good inputs.

As part of this change, remove the ambiguously-named 'fail' flag and
replace it with 'setkey_error = -EINVAL' for the only test vector that
used it -- the DES weak key test vector.  Note that this tightens the
test to require -EINVAL rather than any error code, but AFAICS this
won't cause any test failure.

Other than that, these new fields aren't set on any test vectors yet.
Later patches will do so.

Add testmgr test vectors for EC-RDSA algorithm for every of five
supported parameters (curves). Because there are no officially published
test vectors for the curves, the vectors are generated by gost-engine.

Some public key algorithms (like EC-DSA) keep in parameters field
important data such as digest and curve OIDs (possibly more for
different EC-DSA variants). Thus, just setting a public key (as
for RSA) is not enough.

Append parameters into the key stream for akcipher_set_{pub,priv}_key.
Appended data is: (u32) algo OID, (u32) parameters length, parameters
data.

This does not affect current akcipher API nor RSA ciphers (they could
ignore it). Idea of appending parameters to the key stream is by Herbert
Xu.

<title>crypto: x86/poly1305 - fix overflow during partial reduction</title>

The x86_64 implementation of Poly1305 produces the wrong result on some
inputs because poly1305_4block_avx2() incorrectly assumes that when
partially reducing the accumulator, the bits carried from limb 'd4' to
limb 'h0' fit in a 32-bit integer.  This is true for poly1305-generic
which processes only one block at a time.  However, it's not true for
the AVX2 implementation, which processes 4 blocks at a time and
therefore can produce intermediate limbs about 4x larger.

Fix it by making the relevant calculations use 64-bit arithmetic rather
than 32-bit.  Note that most of the carries already used 64-bit
arithmetic, but the d4 -&gt; h0 carry was different for some reason.

To be safe I also made the same change to the corresponding SSE2 code,
though that only operates on 1 or 2 blocks at a time.  I don't think
it's really needed for poly1305_block_sse2(), but it doesn't hurt
because it's already x86_64 code.  It *might* be needed for
poly1305_2block_sse2(), but overflows aren't easy to reproduce there.

This bug was originally detected by my patches that improve testmgr to
fuzz algorithms against their generic implementation.  But also add a
test vector which reproduces it directly (in the AVX2 case).
