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

The cipher routines in the crypto API are mostly intended for templates
implementing skcipher modes generically in software, and shouldn't be

Currently, by default crypto self-test failures only result in a
pr_warn() message and an "unknown" status in /proc/crypto. Both of
these are easy to miss. There is also an option to panic the kernel
when a test fails, but that can't be the default behavior.
A crypto self-test failure always indicates a kernel bug, however, and
there's already a standard way to report (recoverable) kernel bugs --
the WARN() family of macros. WARNs are noisier and harder to miss, and
existing test systems already know to look for them in dmesg or via
/proc/sys/kernel/tainted.
Therefore, call WARN() when an algorithm fails its self-tests.

When alg_test() is called from tcrypt.ko rather than from the algorithm
registration code, "driver" is actually the algorithm name, not the
driver name. So it shouldn't be used in places where a driver name is
wanted, e.g. when reporting a test failure or when checking whether the
driver is the generic driver or not.
Fix this for the skcipher algorithm tests by getting the driver name
from the crypto_skcipher that actually got allocated.

As said by Linus:
A symmetric naming is only helpful if it implies symmetries in use.
Otherwise it's actively misleading.
In "kzalloc()", the z is meaningful and an important part of what the
caller wants.
In "kzfree()", the z is actively detrimental, because maybe in the
future we really _might_ want to use that "memfill(0xdeadbeef)" or
something. The "zero" part of the interface isn't even _relevant_.
The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.
Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.
The renaming is done by using the command sequence:
git grep -w --name-only kzfree |\
xargs sed -i 's/kzfree/kfree_sensitive/'
followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.

rfc4543 was missing from the list of algorithms that may treat the end
of the AAD buffer specially.
Also, with rfc4106, rfc4309, rfc4543, and rfc7539esp, the end of the AAD
buffer is actually supposed to contain a second copy of the IV, and
we've concluded that if the IV copies don't match the behavior is
implementation-defined. So, the fuzz tests can't easily test that case.
So, make the fuzz tests only use inputs where the two IV copies match.

This patch enables the selftests for the s390 specific protected key
AES (PAES) cipher implementations:
* cbc-paes-s390
* ctr-paes-s390
* ecb-paes-s390
* xts-paes-s390
PAES is an AES cipher but with encrypted ('protected') key
material. However, the paes ciphers are able to derive an protected
key from clear key material with the help of the pkey kernel module.
So this patch now enables the generic AES tests for the paes
ciphers. Under the hood the setkey() functions rearrange the clear key
values as clear key token and so the pkey kernel module is able to
provide protected key blobs from the given clear key values. The
derived protected key blobs are then used within the paes cipers and
should produce the very same results as the generic AES implementation
with the clear key values.
The s390-paes cipher testlist entries are surrounded
by #if IS_ENABLED(CONFIG_CRYPTO_PAES_S390) because they don't
make any sense on non s390 platforms or without the PAES
cipher implementation.

The whole point of using an AEAD over length-preserving encryption is
that the data is authenticated. However currently the fuzz tests don't
test any inauthentic inputs to verify that the data is actually being
authenticated. And only two algorithms ("rfc4543(gcm(aes))" and
"ccm(aes)") even have any inauthentic test vectors at all.
Therefore, update the AEAD fuzz tests to sometimes generate inauthentic
test vectors, either by generating a (ciphertext, AAD) pair without
using the key, or by mutating an authentic pair that was generated.
To avoid flakiness, only assume this works reliably if the auth tag is
at least 8 bytes. Also account for the rfc4106, rfc4309, and rfc7539esp
algorithms intentionally ignoring the last 8 AAD bytes, and for some
algorithms doing extra checks that result in EINVAL rather than EBADMSG.

In preparation for adding inauthentic input fuzz tests, which don't
require that a generic implementation of the algorithm be available,
refactor test_aead_vs_generic_impl() so that instead there's a
higher-level function test_aead_extra() which initializes a struct
aead_extra_tests_ctx and then calls test_aead_vs_generic_impl() with a
pointer to that struct.
As a bonus, this reduces stack usage.
Also switch from crypto_aead_alg(tfm)->maxauthsize to
crypto_aead_maxauthsize(), now that the latter is available in
<crypto/aead.h>.

The alignment bug in ghash_setkey() fixed by commit 5c6bc4dfa515
("crypto: ghash - fix unaligned memory access in ghash_setkey()")

To improve test coverage, update the tests to sometimes pass misaligned

Currently if the comparison fuzz tests encounter an encryption error
when generating an skcipher or AEAD test vector, they will still test
the decryption side (passing it the uninitialized ciphertext buffer)
and expect it to fail with the same error.
This is sort of broken because it's not well-defined usage of the API to
pass an uninitialized buffer, and furthermore in the AEAD case it's
acceptable for the decryption error to be EBADMSG (meaning "inauthentic
input") even if the encryption error was something else like EINVAL.
Fix this for skcipher by explicitly initializing the ciphertext buffer
on error, and for AEAD by skipping the decryption test on error.

Test vectors for blake2b with various digest sizes. As the algorithm is
the same up to the digest calculation, the key and input data length is
distributed in a way that tests all combinanions of the two over the
digest sizes.
Based on the suggestion from Eric, the following input sizes are tested
[0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
padded and the non-padded input buffers are tested.
blake2b-160 blake2b-256 blake2b-384 blake2b-512
---------------------------------------------------
len=0 | klen=0 klen=1 klen=32 klen=64

len=247 | klen=32 klen=64 klen=0 klen=1
len=256 | klen=64 klen=0 klen=1 klen=32
Where key:
- klen=0: empty key
- klen=1: 1 byte value 0x42, 'B'
- klen=32: first 32 bytes of the default key, sequence 00..1f
- klen=64: default key, sequence 00..3f
The unkeyed vectors are ordered before keyed, as this is required by
testmgr.

Three variants of AEGIS were proposed for the CAESAR competition, and
only one was selected for the final portfolio: AEGIS128.
The other variants, AEGIS128L and AEGIS256, are not likely to ever turn
up in networking protocols or other places where interoperability
between Linux and other systems is a concern, nor are they likely to
be subjected to further cryptanalysis. However, uninformed users may
think that AEGIS128L (which is faster) is equally fit for use.
So let's remove them now, before anyone starts using them and we are
forced to support them forever.
Note that there are no known flaws in the algorithms or in any of these
implementations, but they have simply outlived their usefulness.

Add a simple atomic notification chain to allow interested parties
to register to receive notification prior to us kicking the bucket.

The largest stack object in this file is now the shash descriptor.
Since there are many other stack variables, this can push it
over the 1024 byte warning limit, in particular with clang and
KASAN:
crypto/testmgr.c:1693:12: error: stack frame size of 1312 bytes in function '__alg_test_hash' [-Werror,-Wframe-larger-than=]
Make test_hash_vs_generic_impl() do the same thing as the
corresponding eaed and skcipher functions by allocating the
descriptor dynamically. We can still do better than this,
but it brings us well below the 1024 byte limit.

On arm32, we get warnings about high stack usage in some of the functions:
crypto/testmgr.c:2269:12: error: stack frame size of 1032 bytes in function 'alg_test_aead' [-Werror,-Wframe-larger-than=]
static int alg_test_aead(const struct alg_test_desc *desc, const char *driver,
^
crypto/testmgr.c:1693:12: error: stack frame size of 1312 bytes in function '__alg_test_hash' [-Werror,-Wframe-larger-than=]
static int __alg_test_hash(const struct hash_testvec *vecs,
^
On of the larger objects on the stack here is struct testvec_config, so
change that to dynamic allocation.

There are no remaining users of the cipher implementation, and there
are no meaningful ways in which the arc4 cipher can be combined with
templates other than ECB (and the way we do provide that combination
is highly dubious to begin with).
So let's drop the arc4 cipher altogether, and only keep the ecb(arc4)
skcipher, which is used in various places in the kernel.

Call cond_resched() after each fuzz test iteration. This avoids stall
warnings if fuzz_iterations is set very high for testing purposes.
While we're at it, also call cond_resched() after finishing testing each
test vector.
