crypto: tcrypt - fix skcipher multi-buffer tests for 1420B blocks

2021-11-17T10:04:13+00:00

[ Upstream commit 3ae88f676aa63366ffa9eebb8ae787c7e19f0c57 ]

Commit ad6d66bcac77e ("crypto: tcrypt - include 1420 byte blocks in aead and skcipher benchmarks")
mentions:
> power-of-2 block size. So let's add 1420 bytes explicitly, and round
> it up to the next blocksize multiple of the algo in question if it
> does not support 1420 byte blocks.
but misses updating skcipher multi-buffer tests.

Fix this by using the proper (rounded) input size.

crypto: tcrypt - Fix missing return value check

2021-09-15T08:02:05+00:00

[ Upstream commit 7b3d52683b3a47c0ba1dfd6b5994a3a795b06972 ]

There are several places where the return value check of crypto_aead_setkey
and crypto_aead_setauthsize were lost. It is necessary to add these checks.

At the same time, move the crypto_aead_setauthsize() call out of the loop,
and only need to call it once after load transform.

crypto: tcrypt - enable tests for xxhash and blake2

2021-05-28T07:11:45+00:00

Fill some of the recently freed up slots in tcrypt with xxhash64 and
blake2b/blake2s, so we can easily benchmark their kernel implementations
from user space.

crypto: serpent - get rid of obsolete tnepres variant

2021-02-10T06:55:56+00:00

It is not trivial to trace back why exactly the tnepres variant of
serpent was added ~17 years ago - Google searches come up mostly empty,
but it seems to be related with the 'kerneli' version, which was based
on an incorrect interpretation of the serpent spec.

In other words, nobody is likely to care anymore today, so let's get rid
of it.

crypto: salsa20 - remove Salsa20 stream cipher algorithm

2021-01-29T05:07:04+00:00

Salsa20 is not used anywhere in the kernel, is not suitable for disk
encryption, and widely considered to have been superseded by ChaCha20.
So let's remove it.

crypto: tgr192 - remove Tiger 128/160/192 hash algorithms

2021-01-29T05:07:04+00:00

Tiger is never referenced anywhere in the kernel, and unlikely
to be depended upon by userspace via AF_ALG. So let's remove it.

crypto: tcrypt - avoid signed overflow in byte count

2021-01-02T21:41:34+00:00

The signed long type used for printing the number of bytes processed in
tcrypt benchmarks limits the range to -/+ 2 GiB, which is not sufficient
to cover the performance of common accelerated ciphers such as AES-NI
when benchmarked with sec=1. So switch to u64 instead.

While at it, fix up a missing printk->pr_cont conversion in the AEAD
benchmark.
