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 crc64-rocksoft from the crypto API. It has no known user now
that the lib is no longer built on top of it. It was also added much
more recently than the longstanding crc32 and crc32c. Unlike crc32 and
crc32c, crc64-rocksoft is also not mentioned in the dm-integrity
documentation and there are no references to it in anywhere in the
cryptsetup git repo, so it is unlikely to have any user there either.
Also, this CRC variant is named incorrectly; it has nothing to do with
Rocksoft and should be called crc64-nvme. That is yet another reason to
remove it from the crypto API; we would not want anyone to start
depending on the current incorrect algorithm name of crc64-rocksoft.
Note that this change temporarily makes this CRC variant not be covered
by any tests, as previously it was relying on the crypto self-tests.
This will be fixed by adding this CRC variant to crc_kunit.

The keywrap (kw) algorithm has no in-tree user. It has never had an
in-tree user, and the patch that added it provided no justification for
its inclusion. Even use of it via AF_ALG is impossible, as it uses a
weird calling convention where part of the ciphertext is returned via
the IV buffer, which is not returned to userspace in AF_ALG.
It's also unclear whether any new code in the kernel that does key
wrapping would actually use this algorithm. It is controversial in the
cryptographic community due to having no clearly stated security goal,
no security proof, poor performance, and only a 64-bit auth tag. Later
work (https://eprint.iacr.org/2006/221) suggested that the goal is
deterministic authenticated encryption. But there are now more modern
algorithms for this, and this is not the same as key wrapping, for which
a regular AEAD such as AES-GCM usually can be (and is) used instead.
Therefore, remove this unused code.
There were several special cases for this algorithm in the self-tests,
due to its weird calling convention. Remove those too.

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 f1939f7c56 ("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 4bd96a7a81 ("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 ed331adab3 ("crypto: vmac - add nonced version with big
endian digest") and commit 0917b87312 ("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.

Commit 1e562deace ("crypto: rsassa-pkcs1 - Migrate to sig_alg backend")
enforced that rsassa-pkcs1 sign/verify operations specify a hash
algorithm. That is necessary because per RFC 8017 sec 8.2, a hash
algorithm identifier must be prepended to the hash before generating or
verifying the signature ("Full Hash Prefix").
However the commit went too far in that it changed user space behavior:
KEYCTL_PKEY_QUERY system calls now return -EINVAL unless they specify a
hash algorithm. Intel Wireless Daemon (iwd) is one application issuing
such system calls (for EAP-TLS).
Closer analysis of the Embedded Linux Library (ell) used by iwd reveals
that the problem runs even deeper: When iwd uses TLS 1.1 or earlier, it
not only queries for keys, but performs sign/verify operations without
specifying a hash algorithm. These legacy TLS versions concatenate an
MD5 to a SHA-1 hash and omit the Full Hash Prefix:
https://git.kernel.org/pub/scm/libs/ell/ell.git/tree/ell/tls-suites.c#n97
TLS 1.1 was deprecated in 2021 by RFC 8996, but removal of support was
inadvertent in this case. It probably should be coordinated with iwd
maintainers first.
So reinstate support for such legacy protocols by defaulting to hash
algorithm "none" which uses an empty Full Hash Prefix.
If it is later on decided to remove TLS 1.1 support but still allow
KEYCTL_PKEY_QUERY without a hash algorithm, that can be achieved by
reverting the present commit and replacing it with the following patch:
https://lore.kernel.org/r/ZxalYZwH5UiGX5uj@wunner.de/
It's worth noting that Python's cryptography library gained support for
such legacy use cases very recently, so they do seem to still be a thing.
The Python developers identified IKE version 1 as another protocol
omitting the Full Hash Prefix:
https://github.com/pyca/cryptography/issues/10226https://github.com/pyca/cryptography/issues/5495
The author of those issues, Zoltan Kelemen, spent considerable effort
searching for test vectors but only found one in a 2019 blog post by
Kevin Jones. Add it to testmgr.h to verify correctness of this feature.
Examination of wpa_supplicant as well as various IKE daemons (libreswan,
strongswan, isakmpd, raccoon) has determined that none of them seems to
use the kernel's Key Retention Service, so iwd is the only affected user
space application known so far.

Alternatively to the X9.62 encoding of ecdsa signatures, which uses
ASN.1 and is already supported by the kernel, there's another common
encoding called P1363. It stores r and s as the concatenation of two
big endian, unsigned integers. The name originates from IEEE P1363.
Add a P1363 template in support of the forthcoming SPDM library
(Security Protocol and Data Model) for PCI device authentication.
P1363 is prescribed by SPDM 1.2.1 margin no 44:
"For ECDSA signatures, excluding SM2, in SPDM, the signature shall be
the concatenation of r and s. The size of r shall be the size of
the selected curve. Likewise, the size of s shall be the size of
the selected curve. See BaseAsymAlgo in NEGOTIATE_ALGORITHMS for
the size of r and s. The byte order for r and s shall be in big
endian order. When placing ECDSA signatures into an SPDM signature
field, r shall come first followed by s."

Unlike the rsa driver, which separates signature decoding and
signature verification into two steps, the ecdsa driver does both in one.
This restricts users to the one signature format currently supported
(X9.62) and prevents addition of others such as P1363, which is needed
by the forthcoming SPDM library (Security Protocol and Data Model) for
PCI device authentication.
Per Herbert's suggestion, change ecdsa to use a "raw" signature encoding
and then implement X9.62 and P1363 as templates which convert their
respective encodings to the raw one. One may then specify
"x962(ecdsa-nist-XXX)" or "p1363(ecdsa-nist-XXX)" to pick the encoding.
The present commit moves X9.62 decoding to a template. A separate
commit is going to introduce another template for P1363 decoding.
The ecdsa driver internally represents a signature as two u64 arrays of
size ECC_MAX_BYTES. This appears to be the most natural choice for the
raw format as it can directly be used for verification without having to
further decode signature data or copy it around.
Repurpose all the existing test vectors for "x962(ecdsa-nist-XXX)" and
create a duplicate of them to test the raw encoding.

A sig_alg backend has just been introduced with the intent of moving all
asymmetric sign/verify algorithms to it one by one.
Migrate the sign/verify operations from rsa-pkcs1pad.c to a separate
rsassa-pkcs1.c which uses the new backend.
Consequently there are now two templates which build on the "rsa"
akcipher_alg:
* The existing "pkcs1pad" template, which is instantiated as an
akcipher_instance and retains the encrypt/decrypt operations of
RSAES-PKCS1-v1_5 (RFC 8017 sec 7.2).
* The new "pkcs1" template, which is instantiated as a sig_instance
and contains the sign/verify operations of RSASSA-PKCS1-v1_5
(RFC 8017 sec 8.2).
In a separate step, rsa-pkcs1pad.c could optionally be renamed to
rsaes-pkcs1.c for clarity. Additional "oaep" and "pss" templates
could be added for RSAES-OAEP and RSASSA-PSS.
Note that it's currently allowed to allocate a "pkcs1pad(rsa)" transform
without specifying a hash algorithm. That makes sense if the transform
is only used for encrypt/decrypt and continues to be supported. But for
sign/verify, such transforms previously did not insert the Full Hash
Prefix into the padding. The resulting message encoding was incompliant
with EMSA-PKCS1-v1_5 (RFC 8017 sec 9.2) and therefore nonsensical.
From here on in, it is no longer allowed to allocate a transform without
specifying a hash algorithm if the transform is used for sign/verify
operations. This simplifies the code because the insertion of the Full
Hash Prefix is no longer optional, so various "if (digest_info)" clauses
can be removed.
There has been a previous attempt to forbid transform allocation without
specifying a hash algorithm, namely by commit c0d20d22e0 ("crypto:
rsa-pkcs1pad - Require hash to be present"). It had to be rolled back
with commit b3a8c8a5eb ("crypto: rsa-pkcs1pad: Allow hash to be
optional [ver #2]"), presumably because it broke allocation of a
transform which was solely used for encrypt/decrypt, not sign/verify.
Avoid such breakage by allowing transform allocation for encrypt/decrypt
with and without specifying a hash algorithm (and simply ignoring the
hash algorithm in the former case).
So again, specifying a hash algorithm is now mandatory for sign/verify,
but optional and ignored for encrypt/decrypt.
The new sig_alg API uses kernel buffers instead of sglists, which
avoids the overhead of copying signature and digest from sglists back
into kernel buffers. rsassa-pkcs1.c is thus simplified quite a bit.
sig_alg is always synchronous, whereas the underlying "rsa" akcipher_alg
may be asynchronous. So await the result of the akcipher_alg, similar
to crypto_akcipher_sync_{en,de}crypt().
As part of the migration, rename "rsa_digest_info" to "hash_prefix" to
adhere to the spec language in RFC 9580. Otherwise keep the code
unmodified wherever possible to ease reviewing and bisecting. Leave
several simplification and hardening opportunities to separate commits.
rsassa-pkcs1.c uses modern __free() syntax for allocation of buffers
which need to be freed by kfree_sensitive(), hence a DEFINE_FREE()
clause for kfree_sensitive() is introduced herein as a byproduct.

Commit 6cb8815f41 ("crypto: sig - Add interface for sign/verify")
began a transition of asymmetric sign/verify operations from
crypto_akcipher to a new crypto_sig frontend.
Internally, the crypto_sig frontend still uses akcipher_alg as backend,
however:
"The link between sig and akcipher is meant to be temporary. The
plan is to create a new low-level API for sig and then migrate
the signature code over to that from akcipher."
https://lore.kernel.org/r/ZrG6w9wsb-iiLZIF@gondor.apana.org.au/
"having a separate alg for sig is definitely where we want to
be since there is very little that the two types actually share."
https://lore.kernel.org/r/ZrHlpz4qnre0zWJO@gondor.apana.org.au/
Take the next step of that migration and augment the crypto_sig frontend
with a sig_alg backend to which all algorithms can be moved.
During the migration, there will briefly be signature algorithms that
are still based on crypto_akcipher, whilst others are already based on
crypto_sig. Allow for that by building a fork into crypto_sig_*() API
calls (i.e. crypto_sig_maxsize() and friends) such that one of the two
backends is selected based on the transform's cra_type.

The ECDSA test vectors contain "params", "param_len" and "algo" elements
even though ecdsa.c doesn't make any use of them. The only algorithm
implementation using those elements is ecrdsa.c.
Drop the unused test vector elements.
For the curious, "params" is an ASN.1 SEQUENCE of OID_id_ecPublicKey
and a second OID identifying the curve. For example:
"\x30\x13\x06\x07\x2a\x86\x48\xce\x3d\x02\x01\x06\x08\x2a\x86\x48"
"\xce\x3d\x03\x01\x01"

SEQUENCE (OID_id_ecPublicKey, OID_id_prime192v1)

OID_id_prime256v1 (2a8648ce3d030107)
OID_id_ansip384r1 (2b81040022)
OID_id_ansip521r1 (2b81040023)
Those are just different names for secp192r1, secp256r1, secp384r1 and

broke we have to revert the change.
It may be possible that some parts of this commit can be reinstated

It shall be omitted if the version is 0 and shall contain at least
one instance of OtherPrimeInfo if the version is 1, see:

BLAKE2s has no currently known use as an shash. Just remove all of this
unnecessary plumbing. Removing this shash was something we talked about
back when we were making BLAKE2s a built-in, but I simply never got
around to doing it. So this completes that project.
Importantly, this fixs a bug in which the lib code depends on
crypto_simd_disabled_for_test, causing linker errors.
Also add more alignment tests to the selftests and compare SIMD and
non-SIMD compression functions, to make up for what we lose from
testmgr.c.

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 support for POLYVAL, an ε-Δ-universal hash function similar to
GHASH. This patch only uses POLYVAL as a component to implement HCTR2
mode. It should be noted that POLYVAL was originally specified for use
in AES-GCM-SIV (RFC 8452), but the kernel does not currently support
this mode.
POLYVAL is implemented as an shash algorithm. The implementation is
modified from ghash-generic.c.

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.
More information on XCTR mode can be found in the HCTR2 paper:

The only current user of the DH KPP algorithm, the
keyctl(KEYCTL_DH_COMPUTE) syscall, doesn't set the domain parameter ->q
in struct dh. Remove it and any associated (de)serialization code in
crypto_dh_encode_key() and crypto_dh_decode_key. Adjust the encoded
->secret values in testmgr's DH test vectors accordingly.
Note that the dh-generic implementation would have initialized its
struct dh_ctx's ->q from the decoded struct dh's ->q, if present. If this
struct dh_ctx's ->q would ever have been non-NULL, it would have enabled a
full key validation as specified in NIST SP800-56A in dh_is_pubkey_valid().
However, as outlined above, ->q is always NULL in practice and the full key
validation code is effectively dead. A later patch will make
dh_is_pubkey_valid() to calculate Q from P on the fly, if possible, so
don't remove struct dh_ctx's ->q now, but leave it there until that has
happened.
