Remove the "crct10dif" shash algorithm from the crypto API. It has no
known user now that the lib is no longer built on top of it. It has no
remaining references in kernel code. The only other potential users
would be the usual components that allow specifying arbitrary hash
algorithms by name, namely AF_ALG and dm-integrity. However there are
no indications that "crct10dif" is being used with these components.
Debian Code Search and web searches don't find anything relevant, and
explicitly grepping the source code of the usual suspects (cryptsetup,
libell, iwd) finds no matches either. "crc32" and "crc32c" are used in
a few more places, but that doesn't seem to be the case for "crct10dif".
crc_t10dif_update() is also tested by crc_kunit now, so the test
coverage provided via the crypto self-tests is no longer needed.
Also note that the "crct10dif" shash algorithm was inconsistent with the
rest of the shash API in that it wrote the digest in CPU endianness,
making the resulting byte array differ on little endian vs. big endian
platforms. This means it was effectively just built for use by the lib
functions, and it was not actually correct to treat it as "just another
hash function" that could be dropped in via the shash API.

Remove the vmac64 template, as it has no known users. It also continues
to have longstanding bugs such as alignment violations (see
https://lore.kernel.org/r/20241226134847.6690-1-evepolonium@gmail.com/).
This code was added in 2009 by commit f1939f7c5645 ("crypto: vmac - New
hash algorithm for intel_txt support"). Based on the mention of
intel_txt support in the commit title, it seems it was added as a
prerequisite for the contemporaneous patch
"intel_txt: add s3 userspace memory integrity verification"
(https://lore.kernel.org/r/4ABF2B50.6070106@intel.com/). In the design
proposed by that patch, when an Intel Trusted Execution Technology (TXT)
enabled system resumed from suspend, the "tboot" trusted executable
launched the Linux kernel without verifying userspace memory, and then
the Linux kernel used VMAC to verify userspace memory.
However, that patch was never merged, as reviewers had objected to the
design. It was later reworked into commit 4bd96a7a8185 ("x86, tboot:
Add support for S3 memory integrity protection") which made tboot verify
the memory instead. Thus the VMAC support in Linux was never used.
No in-tree user has appeared since then, other than potentially the
usual components that allow specifying arbitrary hash algorithms by
name, namely AF_ALG and dm-integrity. However there are no indications
that VMAC is being used with these components. Debian Code Search and
web searches for "vmac64" (the actual algorithm name) do not return any
results other than the kernel itself, suggesting that it does not appear
in any other code or documentation. Explicitly grepping the source code
of the usual suspects (libell, iwd, cryptsetup) finds no matches either.
Before 2018, the vmac code was also completely broken due to using a
hardcoded nonce and the wrong endianness for the MAC. It was then fixed
by commit ed331adab35b ("crypto: vmac - add nonced version with big
endian digest") and commit 0917b873127c ("crypto: vmac - remove insecure
version with hardcoded nonce"). These were intentionally breaking
changes that changed all the computed MAC values as well as the
algorithm name ("vmac" to "vmac64"). No complaints were ever received
about these breaking changes, strongly suggesting the absence of users.
The reason I had put some effort into fixing this code in 2018 is
because it was used by an out-of-tree driver. But if it is still needed
in that particular out-of-tree driver, the code can be carried in that
driver instead. There is no need to carry it upstream.

Currently, there's mixed use of printk() and pr_info()/pr_err(). The latter
prints the module name (because pr_fmt() is defined so) but the former does
not. As a result there's inconsistency in the printed output. For example:
modprobe mode=211:
[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)
[...] test 1 (160 bit key, 64 byte blocks): 1 operation in 2336 cycles (64 bytes)
modprobe mode=215:

[...] tcrypt: test 1 (160 bit key, 64 byte blocks): 1 operation in 2241 cycles (64 bytes)

For some test cases, a line break gets inserted between the test banner
and the results. For example, with mode=211 this is the output:
[...]
testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] test 0 (160 bit key, 16 byte blocks):
[...] 1 operation in 2373 cycles (16 bytes)
--snip--
[...]
testing speed of gcm(aes) (generic-gcm-aesni) encryption
[...] test 0 (128 bit key, 16 byte blocks):
[...] 1 operation in 2338 cycles (16 bytes)
Similar behavior is seen in the following cases as well:
modprobe tcrypt mode=212
modprobe tcrypt mode=213
modprobe tcrypt mode=221
modprobe tcrypt mode=300 sec=1
modprobe tcrypt mode=400 sec=1
This doesn't happen with mode=215:
[...] tcrypt:
testing speed of multibuffer rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2215 cycles (16 bytes)
--snip--
[...] tcrypt:
testing speed of multibuffer gcm(aes) (generic-gcm-aesni) encryption
[...] tcrypt: test 0 (128 bit key, 16 byte blocks): 1 operation in 2191 cycles (16 bytes)
This print inconsistency is because printk() is used instead of pr_cont()
in a few places. Change these to be pr_cont().
checkpatch warns that pr_cont() shouldn't be used. This can be ignored in
this context as tcrypt already uses pr_cont().

Importantly, this fixs a bug in which the lib code depends on

Also add more alignment tests to the selftests and compare SIMD and

Add support for HCTR2 as a template. HCTR2 is a length-preserving
encryption mode that is efficient on processors with instructions to
accelerate AES and carryless multiplication, e.g. x86 processors with
AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions.
As a length-preserving encryption mode, HCTR2 is suitable for
applications such as storage encryption where ciphertext expansion is
not possible, and thus authenticated encryption cannot be used.
Currently, such applications usually use XTS, or in some cases Adiantum.
XTS has the disadvantage that it is a narrow-block mode: a bitflip will
only change 16 bytes in the resulting ciphertext or plaintext. This
reveals more information to an attacker than necessary.
HCTR2 is a wide-block mode, so it provides a stronger security property:
a bitflip will change the entire message. HCTR2 is somewhat similar to
Adiantum, which is also a wide-block mode. However, HCTR2 is designed
to take advantage of existing crypto instructions, while Adiantum
targets devices without such hardware support. Adiantum is also
designed with longer messages in mind, while HCTR2 is designed to be
efficient even on short messages.
HCTR2 requires POLYVAL and XCTR as components. More information on
HCTR2 can be found here: "Length-preserving encryption with HCTR2":

Add a generic implementation of XCTR mode as a template. XCTR is a
blockcipher mode similar to CTR mode. XCTR uses XORs and little-endian
addition rather than big-endian arithmetic which has two advantages: It
is slightly faster on little-endian CPUs and it is less likely to be
implemented incorrect since integer overflows are not possible on
practical input sizes. XCTR is used as a component to implement HCTR2.

Currently we do not distinguish between algorithms that fail on
the self-test vs. those which are disabled in FIPS mode (not allowed).
Both are marked as having failed the self-test.
Recently the need arose to allow the usage of certain algorithms only
as arguments to specific template instantiations in FIPS mode. For
example, standalone "dh" must be blocked, but e.g. "ffdhe2048(dh)" is
allowed. Other potential use cases include "cbcmac(aes)", which must
only be used with ccm(), or "ghash", which must be used only for
gcm().
This patch allows this scenario by adding a new flag FIPS_INTERNAL to
indicate those algorithms that are not FIPS-allowed. They can then be
used as template arguments only, i.e. when looked up via
crypto_grab_spawn() to be more specific. The FIPS_INTERNAL bit gets
propagated upwards recursively into the surrounding template
instances, until the construction eventually matches an explicit
testmgr entry with ->fips_allowed being set, if any.
The behaviour to skip !->fips_allowed self-test executions in FIPS
mode will be retained. Note that this effectively means that
FIPS_INTERNAL algorithms are handled very similarly to the INTERNAL
ones in this regard. It is expected that the FIPS_INTERNAL algorithms
will receive sufficient testing when the larger constructions they're
a part of, if any, get exercised by testmgr.
Note that as a side-effect of this patch algorithms which are not
FIPS-allowed will now return ENOENT instead of ELIBBAD. Hopefully
this is not an issue as some people were relying on this already.

Commit c4741b2305979 ("crypto: run initcalls for generic implementations

this was unintentional: tcrypt.ko currently cannot be built into the core
kernel, and so the subsys_initcall() gets converted into module_init()
under the hood. Given that tcrypt.ko does not implement a generic version
of a crypto algorithm that has to be available early during boot, there
is no point in running the tcrypt init code earlier than implied by
module_init().
However, for crypto development purposes, we will lift the restriction
that tcrypt.ko must be built as a module, and when builtin, it makes sense
for tcrypt.ko (which does its work inside the module init function) to run
as late as possible. So let's switch to late_initcall() instead.

Currently if you speed test a hash that requires a key you'll get an
error because tcrypt does not set a key by default. This patch
allows a key to be set using the new module parameter klen.

When running tcrypt skcipher speed tests, logs contain things like:
testing speed of async ecb(des3_ede) (ecb(des3_ede-generic)) encryption
or:
testing speed of async ecb(aes) (ecb(aes-ce)) encryption
The algorithm implementations are sync, not async.
Fix this inaccuracy.

Add a test vector for the ESSIV mode that is the most widely used,
i.e., using cbc(aes) and sha256, in both skcipher and AEAD modes
(the latter is used by tcrypt to encapsulate the authenc template
or h/w instantiations of the same)
