Currently the simplest use of the shash API is to use
crypto_shash_digest() to digest a whole buffer. However, this still
requires allocating a hash descriptor (struct shash_desc). Many users
don't really want to preallocate one and instead just use a one-off
descriptor on the stack like the following:
{
SHASH_DESC_ON_STACK(desc, tfm);
int err;
desc->tfm = tfm;
err = crypto_shash_digest(desc, data, len, out);
shash_desc_zero(desc);
}
Wrap this in a new helper function crypto_shash_tfm_digest() that can be
used instead of the above.

Added support for batch requests, per crypto engine.

batch of requests. This has the crypto_engine structure as argument
(for cases when more than one crypto-engine is used).
The crypto_engine_alloc_init_and_set function, initializes
crypto-engine, but also, sets the do_batch_requests callback.
On crypto_pump_requests, if do_batch_requests callback is
implemented in a driver, this will be executed. The link between
the requests will be done in driver, if possible.
do_batch_requests is available only if the hardware has support

Added support for executing multiple requests, in parallel,
for crypto engine based on a retry mechanism.
If hardware was unable to execute a backlog request, enqueue it
back in front of crypto-engine queue, to keep the order
of requests.
A new variable is added, retry_support (this is to keep the
backward compatibility of crypto-engine) , which keeps track
whether the hardware has support for retry mechanism and,
also, if can run multiple requests.
If do_one_request() returns:
>= 0: hardware executed the request successfully;
< 0: this is the old error path. If hardware has support for retry
mechanism, the request is put back in front of crypto-engine queue.
For backwards compatibility, if the retry support is not available,
the crypto-engine will work as before.
If hardware queue is full (-ENOSPC), requeue request regardless
of MAY_BACKLOG flag.
If hardware throws any other error code (like -EIO, -EINVAL,
-ENOMEM, etc.) only MAY_BACKLOG requests are enqueued back into
crypto-engine's queue, since the others can be dropped.
The new crypto_engine_alloc_init_and_set function, initializes
crypto-engine, sets the maximum size for crypto-engine software
queue (not hardcoded anymore) and the retry_support variable
is set, by default, to false.
On crypto_pump_requests(), if do_one_request() returns >= 0,
a new request is send to hardware, until there is no space in
hardware and do_one_request() returns < 0.
By default, retry_support is false and crypto-engine will
work as before - will send requests to hardware,
one-by-one, on crypto_pump_requests(), and complete it, on
crypto_finalize_request(), and so on.
To support multiple requests, in each driver, retry_support
must be set on true, and if do_one_request() returns an error
the request must not be freed, since it will be enqueued back
into crypto-engine's queue.
When all drivers, that use crypto-engine now, will be updated for
retry mechanism, the retry_support variable can be removed.

This special case for umul_ppmm for MIPS64r6 was added in
commit bbc25bee37 ("lib/mpi: Fix umul_ppmm() for MIPS64r6"), due to
GCC being inefficient and emitting a __multi3 intrinsic.
There is no such issue with clang; with this patch applied, I can build
this configuration without any problems and there are no link errors
like mentioned in the commit above (which I can still reproduce with
GCC 9.3.0 when that commit is reverted). Only use this definition when
GCC is being used.
This really should have been caught by commit b0c091ae04 ("lib/mpi:

cpuhp multi-instance callbacks only walk forward in cpuhp_step->list and

As the Jitter RNG provides an SP800-90B compliant noise source, use this
noise source always for the (re)seeding of the DRBG.
To make sure the DRBG is always properly seeded, the reseed threshold
is reduced to 1<<20 generate operations.
The Jitter RNG may report health test failures. Such health test
failures are treated as transient as follows. The DRBG will not reseed
from the Jitter RNG (but from get_random_bytes) in case of a health
test failure. Though, it produces the requested random number.
The Jitter RNG has a failure counter where at most 1024 consecutive
resets due to a health test failure are considered as a transient error.
If more consecutive resets are required, the Jitter RNG will return
a permanent error which is returned to the caller by the DRBG. With this
approach, the worst case reseed threshold is significantly lower than
mandated by SP800-90A in order to seed with an SP800-90B noise source:
the DRBG has a reseed threshold of 2^20 * 1024 = 2^30 generate requests.
Yet, in case of a transient Jitter RNG health test failure, the DRBG is
seeded with the data obtained from get_random_bytes.
However, if the Jitter RNG fails during the initial seeding operation
even due to a health test error, the DRBG will send an error to the
caller because at that time, the DRBG has received no seed that is
SP800-90B compliant.

SP800-90B specifies various requirements for the noise source(s) that
may seed any DRNG including SP800-90A DRBGs. In November 2020,
SP800-90B will be mandated for all noise sources that provide entropy
to DRBGs as part of a FIPS 140-[2|3] validation or other evaluation
types. Without SP800-90B compliance, a noise source is defined to always
deliver zero bits of entropy.
This patch ports the SP800-90B compliance from the user space Jitter RNG
version 2.2.0.
The following changes are applied:
- addition of (an enhanced version of) the repetitive count test (RCT)
from SP800-90B section 4.4.1 - the enhancement is due to the fact of
using the stuck test as input to the RCT.
- addition of the adaptive proportion test (APT) from SP800-90B section
4.4.2
- update of the power-on self test to perform a test measurement of 1024
noise samples compliant to SP800-90B section 4.3
- remove of the continuous random number generator test which is
replaced by APT and RCT
Health test failures due to the SP800-90B operation are only enforced in
FIPS mode. If a runtime health test failure is detected, the Jitter RNG
is reset. If more than 1024 resets in a row are performed, a permanent
error is returned to the caller.
