The ecc.c file started out as part of the ECDH algorithm but got
moved out into a standalone module later. It does not build without
CRYPTO_DEFAULT_RNG, so now that other modules are using it as well we
can run into this link error:

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.

[ Upstream commit 830536770f968ab33ece123b317e252c269098db ]
Now that the Clang compiler has taken it upon itself to police the
compiler command line, and reject combinations for arguments it views
as incompatible, the AEGIS128 no longer builds correctly, and errors
out like this:
clang-10: warning: ignoring extension 'crypto' because the 'armv7-a'
architecture does not support it [-Winvalid-command-line-argument]
So let's switch to armv8-a instead, which matches the crypto-neon-fp-armv8
FPU profile we specify. Since neither were actually supported by GCC
versions before 4.8, let's tighten the Kconfig dependencies as well so
we won't run into errors when building with an ancient compiler.

Implement a template that wraps a (skcipher,shash) or (aead,shash) tuple
so that we can consolidate the ESSIV handling in fscrypt and dm-crypt and
move it into the crypto API. This will result in better test coverage, and
will allow future changes to make the bare cipher interface internal to the
crypto subsystem, in order to increase robustness of the API against misuse.

Another one for the cipher museum: split off DES core processing into
a separate module so other drivers (mostly for crypto accelerators)
can reuse the code without pulling in the generic DES cipher itself.
This will also permit the cipher interface to be made private to the
crypto API itself once we move the only user in the kernel (CIFS) to
this library interface.

To help avoid confusion, add a comment to ghash-generic.c which explains
the convention that the kernel's implementation of GHASH uses.
Also update the Kconfig help text and module descriptions to call GHASH
a "hash function" rather than a "message digest", since the latter
normally means a real cryptographic hash function, which GHASH is not.

Three variants of AEGIS were proposed for the CAESAR competition, and
only one was selected for the final portfolio: AEGIS128.
The other variants, AEGIS128L and AEGIS256, are not likely to ever turn
up in networking protocols or other places where interoperability
between Linux and other systems is a concern, nor are they likely to
be subjected to further cryptanalysis. However, uninformed users may
think that AEGIS128L (which is faster) is equally fit for use.
So let's remove them now, before anyone starts using them and we are
forced to support them forever.
Note that there are no known flaws in the algorithms or in any of these
implementations, but they have simply outlived their usefulness.

MORUS was not selected as a winner in the CAESAR competition, which
is not surprising since it is considered to be cryptographically
broken [0]. (Note that this is not an implementation defect, but a

Drop aes-generic's version of crypto_aes_expand_key(), and switch to
the key expansion routine provided by the AES library. AES key expansion
is not performance critical, and it is better to have a single version
shared by all AES implementations.

The AES assembler code for x86 isn't actually faster than code
generated by the compiler from aes_generic.c, and considering
the disproportionate maintenance burden of assembler code on
x86, it is better just to drop it entirely. Modern x86 systems
will use AES-NI anyway, and given that the modules being removed
have a dependency on aes_generic already, we can remove them
without running the risk of regressions.

The AES-NI code contains fallbacks for invocations that occur from a
context where the SIMD unit is unavailable, which really only occurs
when running in softirq context that was entered from a hard IRQ that
was taken while running kernel code that was already using the FPU.
That means performance is not really a consideration, and we can just
use the new library code for this use case, which has a smaller
footprint and is believed to be time invariant. This will allow us to
drop the non-SIMD asm routines in a subsequent patch.

Take the existing small footprint and mostly time invariant C code
and turn it into a AES library that can be used for non-performance
critical, casual use of AES, and as a fallback for, e.g., SIMD code
that needs a secondary path that can be taken in contexts where the
SIMD unit is off limits (e.g., in hard interrupts taken from kernel
context)

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

echainiv is the only algorithm or template in the crypto API that is
enabled by default. But there doesn't seem to be a good reason for it.
And it pulls in a lot of stuff as dependencies, like AEAD support and a
"NIST SP800-90A DRBG" including HMAC-SHA256.
The commit which made it default 'm', commit 3491244c62 ("crypto:
echainiv - Set Kconfig default to m"), mentioned that it's needed for
IPsec. However, later commit 32b6170ca5 ("ipv4+ipv6: Make INET*_ESP

Add Elliptic Curve Russian Digital Signature Algorithm (GOST R
34.10-2012, RFC 7091, ISO/IEC 14888-3) is one of the Russian (and since
2018 the CIS countries) cryptographic standard algorithms (called GOST
algorithms). Only signature verification is supported, with intent to be
used in the IMA.
Summary of the changes:
* crypto/Kconfig:
- EC-RDSA is added into Public-key cryptography section.
* crypto/Makefile:
- ecrdsa objects are added.
* crypto/asymmetric_keys/x509_cert_parser.c:
- Recognize EC-RDSA and Streebog OIDs.
* include/linux/oid_registry.h:
- EC-RDSA OIDs are added to the enum. Also, a two currently not
implemented curve OIDs are added for possible extension later (to
not change numbering and grouping).
* crypto/ecc.c:
- Kenneth MacKay copyright date is updated to 2014, because
vli_mmod_slow, ecc_point_add, ecc_point_mult_shamir are based on his
code from micro-ecc.
- Functions needed for ecrdsa are EXPORT_SYMBOL'ed.
- New functions:
vli_is_negative - helper to determine sign of vli;
vli_from_be64 - unpack big-endian array into vli (used for
a signature);
vli_from_le64 - unpack little-endian array into vli (used for
a public key);
vli_uadd, vli_usub - add/sub u64 value to/from vli (used for
increment/decrement);
mul_64_64 - optimized to use __int128 where appropriate, this speeds
up point multiplication (and as a consequence signature
verification) by the factor of 1.5-2;
vli_umult - multiply vli by a small value (speeds up point
multiplication by another factor of 1.5-2, depending on vli sizes);
vli_mmod_special - module reduction for some form of Pseudo-Mersenne
primes (used for the curves A);
vli_mmod_special2 - module reduction for another form of
Pseudo-Mersenne primes (used for the curves B);
vli_mmod_barrett - module reduction using pre-computed value (used
for the curve C);
vli_mmod_slow - more general module reduction which is much slower
(used when the modulus is subgroup order);
vli_mod_mult_slow - modular multiplication;
ecc_point_add - add two points;
ecc_point_mult_shamir - add two points multiplied by scalars in one
combined multiplication (this gives speed up by another factor 2 in
compare to two separate multiplications).
ecc_is_pubkey_valid_partial - additional samity check is added.
- Updated vli_mmod_fast with non-strict heuristic to call optimal
module reduction function depending on the prime value;
- All computations for the previously defined (two NIST) curves should
not unaffected.
* crypto/ecc.h:
- Newly exported functions are documented.
* crypto/ecrdsa_defs.h
- Five curves are defined.
* crypto/ecrdsa.c:
- Signature verification is implemented.
* crypto/ecrdsa_params.asn1, crypto/ecrdsa_pub_key.asn1:
- Templates for BER decoder for EC-RDSA parameters and public key.

To achieve more comprehensive crypto test coverage, I'd like to add fuzz
tests that use random data layouts and request flags.
To be most effective these tests should be part of testmgr, so they
automatically run on every algorithm registered with the crypto API.
However, they will take much longer to run than the current tests and
therefore will only really be intended to be run by developers, whereas
the current tests have a wider audience.
Therefore, add a new kconfig option CONFIG_CRYPTO_MANAGER_EXTRA_TESTS
that can be set by developers to enable these extra, expensive tests.
Similar to the regular tests, also add a module parameter
cryptomgr.noextratests to support disabling the tests.
Finally, another module parameter cryptomgr.fuzz_iterations is added to
control how many iterations the fuzz tests do. Note: for now setting
this to 0 will be equivalent to cryptomgr.noextratests=1. But I opted
for separate parameters to provide more flexibility to add other types
of tests under the "extra tests" category in the future.

The Kconfig lexer supports special characters such as '.' and '/' in

support bare file paths in the source statement.
I do not see a good reason to complicate Kconfig for the room of
ambiguity.
The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.
Make it treewide consistent now.
