UPSTREAM: crypto: lib - remove unneeded selection of XOR_BLOCKS
CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS. It perhaps was thought that it's needed for __crypto_xor, but that's not the case. Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a benchmark when it is initialized. That causes a boot time regression on systems that didn't have it enabled before. Therefore, remove this unnecessary and problematic selection. Bug: 254441685 Fixes: |

UPSTREAM: crypto: blake2s - move update and final logic to internal/blake2s.h
Move most of blake2s_update() and blake2s_final() into new inline
functions __blake2s_update() and __blake2s_final() in
include/crypto/internal/blake2s.h so that this logic can be shared by
the shash helper functions. This will avoid duplicating this logic
between the library and shash implementations.

crypto: lib/chacha20poly1305 - Set SG_MITER_ATOMIC unconditionally
There is no reason for the chacha20poly1305 SG miter code to use kmap instead of kmap_atomic as the critical section doesn't sleep anyway. So we can simply get rid of the preemptible check and set SG_MITER_ATOMIC unconditionally. Even if we need to reenable preemption to lower latency we should be doing that by interrupting the SG miter walk rather than using kmap.

crypto: lib/sha1 - remove unnecessary includes of linux/cryptohash.h
<linux/cryptohash.h> sounds very generic and important, like it's the header to include if you're doing cryptographic hashing in the kernel. But actually it only includes the library implementation of the SHA-1 compression function (not even the full SHA-1). This should basically never be used anymore; SHA-1 is no longer considered secure, and there are much better ways to do cryptographic hashing in the kernel. Most files that include this header don't actually need it. So in preparation for removing it, remove all these unneeded includes of it.

crypto: arm64/chacha - correctly walk through blocks
Prior, passing in chunks of 2, 3, or 4, followed by any additional
chunks would result in the chacha state counter getting out of sync,
resulting in incorrect encryption/decryption, which is a pretty nasty
crypto vuln: "why do images look weird on webpages?" WireGuard users
never experienced this prior, because we have always, out of tree, used
a different crypto library, until the recent Frankenzinc addition. This
commit fixes the issue by advancing the pointers and state counter by
the actual size processed. It also fixes up a bug in the (optional,
costly) stride test that prevented it from running on arm64.

crypto: chacha20poly1305 - prevent integer overflow on large input
This code assigns src_len (size_t) to sl (int), which causes problems
when src_len is very large. Probably nobody in the kernel should be
passing this much data to chacha20poly1305 all in one go anyway, so I
don't think we need to change the algorithm or introduce larger types
or anything. But we should at least error out early in this case and
print a warning so that we get reports if this does happen and can look
into why anybody is possibly passing it that much data or if they're
accidently passing -1 or similar.

crypto: chacha20poly1305 - add back missing test vectors and test chunking
When this was originally ported, the 12-byte nonce vectors were left out to keep things simple. I agree that we don't need nor want a library interface for 12-byte nonces. But these test vectors were specially crafted to look at issues in the underlying primitives and related interactions. Therefore, we actually want to keep around all of the test vectors, and simply have a helper function to test them with. Secondly, the sglist-based chunking code in the library interface is rather complicated, so this adds a developer-only test for ensuring that all the book keeping is correct, across a wide array of possibilities.

crypto: curve25519 - Fix selftest build error
If CRYPTO_CURVE25519 is y, CRYPTO_LIB_CURVE25519_GENERIC will be
y, but CRYPTO_LIB_CURVE25519 may be set to m, this causes build
errors:
lib/crypto/curve25519-selftest.o: In function `curve25519':
curve25519-selftest.c:(.text.unlikely+0xc): undefined reference to `curve25519_arch'
lib/crypto/curve25519-selftest.o: In function `curve25519_selftest':
curve25519-selftest.c:(.init.text+0x17e): undefined reference to `curve25519_base_arch'
This is because the curve25519 self-test code is being controlled
by the GENERIC option rather than the overall CURVE25519 option,
as is the case with blake2s. To recap, the GENERIC and ARCH options
for CURVE25519 are internal only and selected by users such as
the Crypto API, or the externally visible CURVE25519 option which
in turn is selected by wireguard. The self-test is specific to the
the external CURVE25519 option and should not be enabled by the
Crypto API.
This patch fixes this by splitting the GENERIC module from the
CURVE25519 module with the latter now containing just the self-test.

These x86_64 vectorized implementations support AVX, AVX-2, and AVX512F.
The AVX-512F implementation is disabled on Skylake, due to throttling,
but it is quite fast on >= Cannonlake.
On the left is cycle counts on a Core i7 6700HQ using the AVX-2
codepath, comparing this implementation ("new") to the implementation in
the current crypto api ("old"). On the right are benchmarks on a Xeon
Gold 5120 using the AVX-512 codepath. The new implementation is faster
on all benchmarks.

This commit wires in the prior implementation from Andy, and makes the
following changes to be suitable for kernel land.
- Some cosmetic and structural changes, like renaming labels to
.Lname, constants, and other Linux conventions, as well as making
the code easy for us to maintain moving forward.
- CPU feature checking is done in C by the glue code.
- We avoid jumping into the middle of functions, to appease objtool,
and instead parameterize shared code.
- We maintain frame pointers so that stack traces make sense.
- We remove the dependency on the perl xlate code, which transforms
the output into things that assemblers we don't care about use.
Importantly, none of our changes affect the arithmetic or core code, but
just involve the differing environment of kernel space.

crypto: poly1305 - add new 32 and 64-bit generic versions
These two C implementations from Zinc -- a 32x32 one and a 64x64 one, depending on the platform -- come from Andrew Moon's public domain poly1305-donna portable code, modified for usage in the kernel. The precomputation in the 32-bit version and the use of 64x64 multiplies in the 64-bit version make these perform better than the code it replaces. Moon's code is also very widespread and has received many eyeballs of scrutiny. There's a bit of interference between the x86 implementation, which relies on internal details of the old scalar implementation. In the next commit, the x86 implementation will be replaced with a faster one that doesn't rely on this, so none of this matters much. But for now, to keep this passing the tests, we inline the bits of the old implementation that the x86 implementation relied on. Also, since we now support a slightly larger key space, via the union, some offsets had to be fixed up. Nonce calculation was folded in with the emit function, to take advantage of 64x64 arithmetic. However, Adiantum appeared to rely on no nonce handling in emit, so this path was conditionalized. We also introduced a new struct, poly1305_core_key, to represent the precise amount of space that particular implementation uses. Testing with kbench9000, depending on the CPU, the update function for the 32x32 version has been improved by 4%-7%, and for the 64x64 by 19%-30%. The 32x32 gains are small, but I think there's great value in having a parallel implementation to the 64x64 one so that the two can be compared side-by-side as nice stand-alone units.

crypto: lib/chacha20poly1305 - reimplement crypt_from_sg() routine
Reimplement the library routines to perform chacha20poly1305 en/decryption on scatterlists, without [ab]using the [deprecated] blkcipher interface, which is rather heavyweight and does things we don't really need. Instead, we use the sg_miter API in a novel and clever way, to iterate over the scatterlist in-place (i.e., source == destination, which is the only way this library is expected to be used). That way, we don't have to iterate over two scatterlists in parallel. Another optimization is that, instead of relying on the blkcipher walker to present the input in suitable chunks, we recognize that ChaCha is a streamcipher, and so we can simply deal with partial blocks by keeping a block of cipherstream on the stack and use crypto_xor() to mix it with the in/output. Finally, we omit the scatterwalk_and_copy() call if the last element of the scatterlist covers the MAC as well (which is the common case), avoiding the need to walk the scatterlist and kmap() the page twice.

not be inlined, to prevent it from running out of registers and spilling
to the stack. The resulting code performs identically under both GCC

Currently, our generic ChaCha implementation consists of a permute function in lib/chacha.c that operates on the 64-byte ChaCha state directly [and which is always included into the core kernel since it is used by the /dev/random driver], and the crypto API plumbing to expose it as a skcipher. In order to support in-kernel users that need the ChaCha streamcipher but have no need [or tolerance] for going through the abstractions of the crypto API, let's expose the streamcipher bits via a library API as well, in a way that permits the implementation to be superseded by an architecture specific one if provided. So move the streamcipher code into a separate module in lib/crypto, and expose the init() and crypt() routines to users of the library.

crypto: sha256 - Make lib/crypto/sha256.c suitable for generic use
Before this commit lib/crypto/sha256.c has only been used in the s390 and x86 purgatory code, make it suitable for generic use: * Export interesting symbols * Add -D__DISABLE_EXPORTS to CFLAGS_sha256.o for purgatory builds to avoid the exports for the purgatory builds * Add to lib/crypto/Makefile and crypto/Kconfig Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |

crypto: sha256 - Use get/put_unaligned_be32 to get input, memzero_explicit
Use get/put_unaligned_be32 in lib/crypto/sha256.c to load / store data so that it can be used with unaligned buffers too, making it more generic. And use memzero_explicit for better clearing of sensitive data. Note unlike other patches in this series this commit actually makes functional changes to the sha256 code as used by the purgatory code. This fully aligns the lib/crypto/sha256.c sha256 implementation with the one from crypto/sha256_generic.c allowing us to remove the latter in further patches in this series.

crypto: sha256 - Move lib/sha256.c to lib/crypto
Generic crypto implementations belong under lib/crypto not directly in lib, likewise the header should be in include/crypto, not include/linux. Note that the code in lib/crypto/sha256.c is not yet available for generic use after this commit, it is still only used by the s390 and x86 purgatory code. Making it suitable for generic use is done in further patches in this series. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
