Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, change the following form:
sizeof(*sgl) + sizeof(sgl->sg[0]) * (MAX_SGL_ENTS + 1)
to :
struct_size(sgl, sg, MAX_SGL_ENTS + 1)
This code was detected with the help of Coccinelle.

Add 1536 and 4096-byte Adiantum test vectors so that the case where
there are multiple NH hashes is tested. This is already tested by the
nhpoly1305 test vectors, but it should be tested at the Adiantum level
too. Moreover the 4096-byte case is especially important.
As with the other Adiantum test vectors, these were generated by the
reference Python implementation at https://github.com/google/adiantum
and then automatically formatted for testmgr by a script.

This is needed to test that the end of the message is zero-padded when
the length is not a multiple of 16 (NH_MESSAGE_UNIT). It's already
tested indirectly by the 31-byte Adiantum test vector, but it should be
tested directly at the nhpoly1305 level too.

Test that all CTR implementations update the IV buffer to contain the
next counter block, aka the IV to continue the encryption/decryption of
a larger message. When the length processed is a multiple of the block
size, users may rely on this for chaining.
When the length processed is *not* a multiple of the block size, simple
chaining doesn't work. However, as noted in commit 88a3f582bea9
("crypto: arm64/aes - don't use IV buffer to return final keystream
block"), the generic CCM implementation assumes that the CTR IV is
handled in some sane way, not e.g. overwritten with part of the
keystream. Since this was gotten wrong once already, it's desirable to
test for it. And, the most straightforward way to do this is to enforce
that all CTR implementations have the same behavior as the generic
implementation, which returns the *next* counter following the final
partial block. This behavior also has the advantage that if someone
does misuse this case for chaining, then the keystream won't be
repeated. Thus, this patch makes the tests expect this behavior.

Allow skcipher test vectors to declare the value the IV buffer should be
updated to at the end of the encryption or decryption operation.
(This check actually used to be supported in testmgr, but it was never
used and therefore got removed except for the AES-Keywrap special case.
But it will be used by CBC and CTR now, so re-add it.)

Convert alg_test_hash() to use the new test framework, adding a list of
testvec_configs to test by default. When the extra self-tests are
enabled, randomly generated testvec_configs are tested as well.
This improves hash test coverage mainly because now all algorithms have
a variety of data layouts tested, whereas before each algorithm was
responsible for declaring its own chunked test cases which were often
missing or provided poor test coverage. The new code also tests both
the MAY_SLEEP and !MAY_SLEEP cases and buffers that cross pages.
This already found bugs in the hash walk code and in the arm32 and arm64
implementations of crct10dif.
I removed the hash chunked test vectors that were the same as
non-chunked ones, but left the ones that were unique.

Convert alg_test_aead() to use the new test framework, using the same
list of testvec_configs that skcipher testing uses.
This significantly improves AEAD test coverage mainly because previously
there was only very limited test coverage of the possible data layouts.
Now the data layouts to test are listed in one place for all algorithms
and optionally are also randomly generated. In fact, only one AEAD
algorithm (AES-GCM) even had a chunked test case before.
This already found bugs in all the AEGIS and MORUS implementations, the
x86 AES-GCM implementation, and the arm64 AES-CCM implementation.
I removed the AEAD chunked test vectors that were the same as
non-chunked ones, but left the ones that were unique.
Note: the rewritten test code allocates an aead_request just once per
algorithm rather than once per encryption/decryption, but some AEAD
algorithms incorrectly change the tfm pointer in the request. It's
nontrivial to fix these, so to move forward I'm temporarily working
around it by resetting the tfm pointer. But they'll need to be fixed.

This has already found a bug in the arm64 ctr-aes-neonbs algorithm.

To achieve more comprehensive crypto test coverage, I'd like to add fuzz
tests that use random data layouts and request flags.
To be most effective these tests should be part of testmgr, so they
automatically run on every algorithm registered with the crypto API.
However, they will take much longer to run than the current tests and
therefore will only really be intended to be run by developers, whereas
the current tests have a wider audience.
Therefore, add a new kconfig option CONFIG_CRYPTO_MANAGER_EXTRA_TESTS
that can be set by developers to enable these extra, expensive tests.
Similar to the regular tests, also add a module parameter
cryptomgr.noextratests to support disabling the tests.
Finally, another module parameter cryptomgr.fuzz_iterations is added to
control how many iterations the fuzz tests do. Note: for now setting
this to 0 will be equivalent to cryptomgr.noextratests=1. But I opted
for separate parameters to provide more flexibility to add other types
of tests under the "extra tests" category in the future.

Crypto algorithms must produce the same output for the same input
regardless of data layout, i.e. how the src and dst scatterlists are
divided into chunks and how each chunk is aligned. Request flags such
as CRYPTO_TFM_REQ_MAY_SLEEP must not affect the result either.
However, testing of this currently has many gaps. For example,
individual algorithms are responsible for providing their own chunked
test vectors. But many don't bother to do this or test only one or two
cases, providing poor test coverage. Also, other things such as
misaligned IVs and CRYPTO_TFM_REQ_MAY_SLEEP are never tested at all.
Test code is also duplicated between the chunked and non-chunked cases,
making it difficult to make other improvements.
To improve the situation, this patch series basically moves the chunk
descriptions into the testmgr itself so that they are shared by all
algorithms. However, it's done in an extensible way via a new struct
'testvec_config', which describes not just the scaled chunk lengths but
also all other aspects of the crypto operation besides the data itself
such as the buffer alignments, the request flags, whether the operation
is in-place or not, the IV alignment, and for hash algorithms when to
do each update() and when to use finup() vs. final() vs. digest().
Then, this patch series makes skcipher, aead, and hash algorithms be
tested against a list of default testvec_configs, replacing the current
test code. This improves overall test coverage, without reducing test
performance too much. Note that the test vectors themselves are not
changed, except for removing the chunk lists.
This series also adds randomized fuzz tests, enabled by a new kconfig
option intended for developer use only, where skcipher, aead, and hash
algorithms are tested against many randomly generated testvec_configs.
This provides much more comprehensive test coverage.
These improved tests have already exposed many bugs.
To start it off, this initial patch adds the testvec_config and various
helper functions that will be used by the skcipher, aead, and hash test
code that will be converted to use the new testvec_config framework.

Hash algorithms with an alignmask set, e.g. "xcbc(aes-aesni)" and
"michael_mic", fail the improved hash tests because they sometimes
produce the wrong digest. The bug is that in the case where a
scatterlist element crosses pages, not all the data is actually hashed
because the scatterlist walk terminates too early. This happens because
the 'nbytes' variable in crypto_hash_walk_done() is assigned the number
of bytes remaining in the page, then later interpreted as the number of
bytes remaining in the scatterlist element. Fix it.

The generic MORUS implementations all fail the improved AEAD tests
because they produce the wrong result with some data layouts. The issue
is that they assume that if the skcipher_walk API gives 'nbytes' not
aligned to the walksize (a.k.a. walk.stride), then it is the end of the
data. In fact, this can happen before the end. Fix them.

Instantiating "cryptd(crc32c)" causes a crypto self-test failure because
the crypto_alloc_shash() in alg_test_crc32c() fails. This is because
cryptd(crc32c) is an ahash algorithm, not a shash algorithm; so it can
only be accessed through the ahash API, unlike shash algorithms which
can be accessed through both the ahash and shash APIs.
As the test is testing the shash descriptor format which is only
applicable to shash algorithms, skip it for ahash algorithms.
(Note that it's still important to fix crypto self-test failures even
for weird algorithm instantiations like cryptd(crc32c) that no one
would really use; in fips_enabled mode unprivileged users can use them
to panic the kernel, and also they prevent treating a crypto self-test
failure as a bug when fuzzing the kernel.)

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key. Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).
Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused. (This in fact happened in the UX500 driver,
though just in some debugging messages.)
Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

uses SPDX license identifiers for that purpose, which replace the boiler
plate text.

Precise and non-ambiguous license information is important. The recently
added aegis header file has a SPDX license identifier, which is nice, but
at the same time it has a contradictionary license boiler plate text.
SPDX-License-Identifier: GPL-2.0
versus
* This program is free software; you can redistribute it and/or modify it
* under the terms of the GNU General Public License as published by the Free
* Software Foundation; either version 2 of the License, or (at your option)
* any later version
Oh well.
As the other aegis related files are licensed under the GPL v2 or later,
it's assumed that the boiler plate code is correct, but the SPDX license
identifier is wrong.
Fix the SPDX identifier and remove the boiler plate as it is redundant.

Currently testmgr has separate encryption and decryption test vectors
for AEADs. That's massively redundant, since usually the decryption
tests are identical to the encryption tests, just with the input/result
swapped. And for some algorithms it was forgotten to add decryption
test vectors, so for them currently only encryption is being tested.
Therefore, eliminate the redundancy by removing the AEAD decryption test
vectors and updating testmgr to test both AEAD encryption and decryption
using what used to be the encryption test vectors. Naming is adjusted
accordingly: each aead_testvec now has a 'ptext' (plaintext), 'plen'
(plaintext length), 'ctext' (ciphertext), and 'clen' (ciphertext length)
instead of an 'input', 'ilen', 'result', and 'rlen'. "Ciphertext" here
refers to the full ciphertext, including the authentication tag.
For now the scatterlist divisions are just given for the plaintext
length, not also the ciphertext length. For decryption, the last
scatterlist element is just extended by the authentication tag length.
In total, this removes over 5000 lines from testmgr.h, with no reduction
in test coverage since prior patches already copied the few unique
decryption test vectors into the encryption test vectors.
The testmgr.h portion of this patch was automatically generated using
the following awk script, except that I also manually updated the
definition of 'struct aead_testvec' and fixed the location of the
comment describing the AEGIS-128 test vectors.
BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER }
/^static const struct aead_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC }
/^static const struct aead_testvec.*_dec_/ { mode = DECVEC }
mode == ENCVEC {
sub(/\.input[[:space:]]*=/, ".ptext\t=")
sub(/\.result[[:space:]]*=/, ".ctext\t=")
sub(/\.ilen[[:space:]]*=/, ".plen\t=")
sub(/\.rlen[[:space:]]*=/, ".clen\t=")
print
}
mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER }
mode == OTHER { print }
mode == ENCVEC && /^};/ { mode = OTHER }
mode == DECVEC && /^};/ { mode = DECVEC_TAIL }
Note that git's default diff algorithm gets confused by the testmgr.h
portion of this patch, and reports too many lines added and removed.
It's better viewed with 'git diff --minimal' (or 'git show --minimal'),
which reports "2 files changed, 1235 insertions(+), 6491 deletions(-)".

One "rfc4543(gcm(aes))" decryption test vector doesn't exactly match any of the
encryption test vectors with input and result swapped. In preparation
for removing the AEAD decryption test vectors and testing AEAD
decryption using the encryption test vectors, add this to the encryption
test vectors, so we don't lose any test coverage.

In preparation for unifying the AEAD encryption and decryption test
vectors, skip AEAD test vectors with the 'novrfy' (verification failure
expected) flag set when testing encryption rather than decryption.
These test vectors only make sense for decryption.

Before this, if akcipher_testvec have `public_key_vec' set to true
(i.e. having a public key) only sign/encrypt test is performed, but
verify/decrypt test is skipped.
With a public key we could do encrypt and verify, but to sign and decrypt
a private key is required.
This logic is correct for encrypt/decrypt tests (decrypt is skipped if
no private key). But incorrect for sign/verify tests - sign is performed
no matter if there is no private key, but verify is skipped if there is
a public key.
Rework `test_akcipher_one' to arrange tests properly depending on value
of `public_key_vec` and `siggen_sigver_test'.
No tests were missed since there is only one sign/verify test (which
have `siggen_sigver_test' set to true) and it has a private key, but
future tests could benefit from this improvement.

crypto_init_shash_ops_async() only gives the ahash tfm non-NULL
->export() and ->import() if the underlying shash alg has these
non-NULL. This doesn't make sense because when an shash algorithm is
registered, shash_prepare_alg() sets a default ->export() and ->import()
if the implementor didn't provide them. And elsewhere it's assumed that
all shash algs and ahash tfms have non-NULL ->export() and ->import().
Therefore, remove these unnecessary, always-true conditions.
