At present, as HPRE/SEC/ZIP modules' parameter 'pf_q_num' is 1,
kernel CRYPTO test will fail on the algorithms from the modules,
since 'QP' hardware resources are not enough for CRYPTO TFM.
To fix this, the minimum value of 'pf_q_num' should be 2.

On systems with coherence issues, packet processed could succeed while
it should have failed, e.g. because of an authentication fail.
This is because the driver would read stale status information that had
all error bits initialised to zero = no error.
Since this is potential a security risk, we want to prevent it from being
a possibility at all. So initialize all error bits to error state, so
that reading stale status information will always result in errors.

This patch also fixes the incorrect endianness markings in the
sun4i-ss driver. It should have no effect in the genereated code.
Instead of using cpu_to_Xe32 followed by a memcpy, this patch
converts the final hash write to use put_unaligned_X instead.

Since commit b56f5cbc7e08ec7d31c42fc41e5247677f20b143 ("crypto:
arm/aes-neonbs - resolve fallback cipher at runtime") the CBC
encryption path in aes-neonbs is now identical to that obtained
through the cbc template. This means that it can simply call
the generic cbc template instead of doing its own thing.
This patch removes the custom encryption path and simply invokes
the generic cbc template.

Cryptographic algorithms may have a lifespan that is significantly
shorter than Linux's, and so we need to start phasing out algorithms
that are known to be broken, and are no longer fit for general use.
RC4 (or arc4) is a good example here: there are a few areas where its
use is still somewhat acceptable, e.g., for interoperability with legacy
wifi hardware that can only use WEP or TKIP data encryption, but that
should not imply that, for instance, use of RC4 based EAP-TLS by the WPA
supplicant for negotiating TKIP keys is equally acceptable, or that RC4
should remain available as a general purpose cryptographic transform for
all in-kernel and user space clients.
Now that all in-kernel users that need to retain support have moved to
the arc4 library interface, and the known users of ecb(arc4) via the
socket API (iwd [0] and libell [1][2]) have been updated to switch to a
local implementation, we can take the next step, and mark the ecb(arc4)
skcipher as obsolete, and only provide it if the socket API is enabled in
the first place, as well as provide the option to disable all algorithms
that have been marked as obsolete.

The RC4-HMAC-MD5 KerberosV algorithm is based on RFC 4757 [0], which
was specifically issued for interoperability with Windows 2000, but was
never intended to receive the same level of support. The RFC says
The IETF Kerberos community supports publishing this specification as
an informational document in order to describe this widely
implemented technology. However, while these encryption types
provide the operations necessary to implement the base Kerberos
specification [RFC4120], they do not provide all the required
operations in the Kerberos cryptography framework [RFC3961]. As a
result, it is not generally possible to implement potential
extensions to Kerberos using these encryption types. The Kerberos
encryption type negotiation mechanism [RFC4537] provides one approach
for using such extensions even when a Kerberos infrastructure uses
long-term RC4 keys. Because this specification does not implement
operations required by RFC 3961 and because of security concerns with
the use of RC4 and MD4 discussed in Section 8, this specification is
not appropriate for publication on the standards track.
The RC4-HMAC encryption types are used to ease upgrade of existing
Windows NT environments, provide strong cryptography (128-bit key
lengths), and provide exportable (meet United States government
export restriction requirements) encryption. This document describes
the implementation of those encryption types.
Furthermore, this RFC was re-classified as 'historic' by RFC 8429 [1] in
2018, stating that 'none of the encryption types it specifies should be
used'
Note that other outdated algorithms are left in place (some of which are
guarded by CONFIG_SUNRPC_DISABLE_INSECURE_ENCTYPES), so this should only
adversely affect interoperability with Windows NT/2000 systems that have
not received any updates since 2008 (but are connected to a network
nonetheless)

The RNGB can generate 2^20 words (1 word == 4 byte) of 'random' data
after the seed pool was initialized. The pool needs to be reseeded if
more words are required. The reseeding is done automatically since
commit 3acd9ea9331c ("hwrng: imx-rngc - use automatic seeding").
We can't retrieve the TRNG values directly so we need a other way to get
the quality level. We know that the PRNG uses 20.000 entropy samples
from the TRNG to generate 2^20 words (1MiB) and the quality level is
defined as (in bits of entropy per 1024 bits of input). So the quality
level can be calculated by:
20.000 * 1024
------------- = ~ 19.5
