crypto: arm64/sha256 - increase cra_priority of scalar implementations
Commit
b73b7ac0a774 ("crypto: sha256_generic - add cra_priority") gave
sha256-generic and sha224-generic a cra_priority of 100, to match the
convention for generic implementations. But sha256-arm64 and
sha224-arm64 also have priority 100, so their order relative to the
generic implementations became ambiguous.
Therefore, increase their priority to 125 so that they have higher
priority than the generic implementations but lower priority than the
NEON implementations which have priority 150.

crypto: x86/sha-mb - decrease priority of multibuffer algorithms
With all the crypto modules enabled on x86, and with a CPU that supports
AVX-2 but not SHA-NI instructions (e.g. Haswell, Broadwell, Skylake),
the "multibuffer" implementations of SHA-1, SHA-256, and SHA-512 are the
highest priority. However, these implementations only perform well when
many hash requests are being submitted concurrently, filling all 8 AVX-2
lanes. Otherwise, they are incredibly slow, as they waste time waiting
for more requests to arrive before proceeding to execute each request.
For example, here are the speeds I see hashing 4096-byte buffers with a
single thread on a Haswell-based processor:
generic avx2 mb (multibuffer)
------- -------- ----------------
sha1 602 MB/s 997 MB/s 0.61 MB/s
sha256 228 MB/s 412 MB/s 0.61 MB/s
sha512 312 MB/s 559 MB/s 0.61 MB/s
So, the multibuffer implementation is 500 to 1000 times slower than the
other implementations. Note that with smaller buffers or more update()s
per digest, the difference would be even greater.
I believe the vast majority of people are in the boat where the
multibuffer code is much slower, and only a small minority are doing the
highly parallel, hashing-intensive, latency-flexible workloads (maybe
IPsec on servers?) where the multibuffer code may be beneficial. Yet,
people often aren't familiar with all the crypto config options and so
the multibuffer code may inadvertently be built into the kernel.
Also the multibuffer code apparently hasn't been very well tested,
seeing as it was sometimes computing the wrong SHA-256 digest.
So, let's make the multibuffer algorithms low priority. Users who want
to use them can either request them explicitly by driver name, or use
NETLINK_CRYPTO (crypto_user) to increase their priority at runtime.

crypto: inside-secure - remove request list to improve performance
This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.
This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.
The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

crypto: vmac - separate tfm and request context
syzbot reported a crash in vmac_final() when multiple threads
concurrently use the same "vmac(aes)" transform through AF_ALG. The bug
is pretty fundamental: the VMAC template doesn't separate per-request
state from per-tfm (per-key) state like the other hash algorithms do,
but rather stores it all in the tfm context. That's wrong.
Also, vmac_final() incorrectly zeroes most of the state including the
derived keys and cached pseudorandom pad. Therefore, only the first
VMAC invocation with a given key calculates the correct digest.
Fix these bugs by splitting the per-tfm state from the per-request state
and using the proper init/update/final sequencing for requests.
Reproducer for the crash:
#include <linux/if_alg.h>

struct sockaddr_alg addr = {
.salg_type = "hash",

setsockopt(fd, SOL_ALG, ALG_SET_KEY, buf, 16);
fork();
fd = accept(fd, NULL, NULL);
for (;;)
write(fd, buf, 256);
}
The immediate cause of the crash is that vmac_ctx_t.partial_size exceeds
VMAC_NHBYTES, causing vmac_final() to memset() a negative length.

A counter is given to the engine when finishing hash computation. It
