91a4855d6c Networking changes for 7.1.
Core & protocols
 ----------------
 
  - Support HW queue leasing, allowing containers to be granted access
    to HW queues for zero-copy operations and AF_XDP.
 
  - Number of code moves to help the compiler with inlining.
    Avoid output arguments for returning drop reason where possible.
 
  - Rework drop handling within qdiscs to include more metadata
    about the reason and dropping qdisc in the tracepoints.
 
  - Remove the rtnl_lock use from IP Multicast Routing.
 
  - Pack size information into the Rx Flow Steering table pointer
    itself. This allows making the table itself a flat array of u32s,
    thus making the table allocation size a power of two.
 
  - Report TCP delayed ack timer information via socket diag.
 
  - Add ip_local_port_step_width sysctl to allow distributing the randomly
    selected ports more evenly throughout the allowed space.
 
  - Add support for per-route tunsrc in IPv6 segment routing.
 
  - Start work of switching sockopt handling to iov_iter.
 
  - Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
    buffer size drifting up.
 
  - Support MSG_EOR in MPTCP.
 
  - Add stp_mode attribute to the bridge driver for STP mode selection.
    This addresses concerns about call_usermodehelper() usage.
 
  - Remove UDP-Lite support (as announced in 2023).
 
  - Remove support for building IPv6 as a module.
    Remove the now unnecessary function calling indirection.
 
 Cross-tree stuff
 ----------------
 
  - Move Michael MIC code from generic crypto into wireless,
    it's considered insecure but some WiFi networks still need it.
 
 Netfilter
 ---------
 
  - Switch nft_fib_ipv6 module to no longer need temporary dst_entry
    object allocations by using fib6_lookup() + RCU.
    Florian W reports this gets us ~13% higher packet rate.
 
  - Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
    switch the service tables to be per-net. Convert some code that
    walks the service lists to use RCU instead of the service_mutex.
 
  - Add more opinionated input validation to lower security exposure.
 
  - Make IPVS hash tables to be per-netns and resizable.
 
 Wireless
 --------
 
  - Finished assoc frame encryption/EPPKE/802.1X-over-auth.
 
  - Radar detection improvements.
 
  - Add 6 GHz incumbent signal detection APIs.
 
  - Multi-link support for FILS, probe response templates and
    client probing.
 
  - New APIs and mac80211 support for NAN (Neighbor Aware Networking,
    aka Wi-Fi Aware) so less work must be in firmware.
 
 Driver API
 ----------
 
  - Add numerical ID for devlink instances (to avoid having to create
    fake bus/device pairs just to have an ID). Support shared devlink
    instances which span multiple PFs.
 
  - Add standard counters for reporting pause storm events
    (implement in mlx5 and fbnic).
 
  - Add configuration API for completion writeback buffering
    (implement in mana).
 
  - Support driver-initiated change of RSS context sizes.
 
  - Support DPLL monitoring input frequency (implement in zl3073x).
 
  - Support per-port resources in devlink (implement in mlx5).
 
 Misc
 ----
 
  - Expand the YAML spec for Netfilter.

8c6d03b7a2 crypto: Remove michael_mic from crypto_shash API
Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used.  Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.

c637f3e4a5 crypto: testmgr - Add missing DES weak and semi-weak key tests
Ever since commit da7f033ddc ("crypto: cryptomgr - Add test
infrastructure"), the DES test suite has tested only one of the four
weak keys and none of the twelve semi-weak keys.

DES has four weak keys and twelve semi-weak keys, and the kernel's DES
implementation correctly detects and rejects all of these keys when the
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS flag is set. However, only a single weak
key was being tested. Add tests for all 16 weak and semi-weak keys.

While DES is deprecated, it is still used in some legacy protocols, and
weak/semi-weak key detection should be tested accordingly.

Tested on arm64 with cryptographic self-tests.

c7dcb041ce crypto: ansi_cprng - Remove unused ansi_cprng algorithm
Remove ansi_cprng, since it's obsolete and unused, as confirmed at
https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/

This was originally added in 2008, apparently as a FIPS approved random
number generator.  Whether this has ever belonged upstream is
questionable.  Either way, ansi_cprng is no longer usable for this
purpose, since it's been superseded by the more modern algorithms in
crypto/drbg.c, and FIPS itself no longer allows it.  (NIST SP 800-131A
Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after
2015.  NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.)

Therefore, there is no reason to keep it around.

Curve25519 is used only via the library API, not the crypto_kpp API.  In
preparation for removing the unused crypto_kpp API for Curve25519,
remove the tests for the "curve25519" kpp from crypto/testmgr.c.

Note that these tests just duplicated lib/crypto/curve25519-selftest.c,
which uses the same list of test vectors.  So they didn't really provide
any additional value.

8522104f75 crypto: crct10dif - remove from crypto API
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.

0fcec0b73a crypto: crc64-rocksoft - remove from crypto 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.

730f67d8b8 crypto: keywrap - remove unused keywrap algorithm
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.

2890601f54 crypto: vmac - remove unused VMAC algorithm
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.

a03a728e37 crypto: rsassa-pkcs1 - Reinstate support for legacy protocols
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/10226
https://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.

b04163863c crypto: ecdsa - Support P1363 signature decoding
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."

d6793ff974 crypto: ecdsa - Move X9.62 signature decoding into template
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 and all asymmetric
sign/verify algorithms have been migrated to it.

The sign/verify operations can thus be dropped from akcipher_alg.
It is now purely for asymmetric encrypt/decrypt.

unexport crypto_akcipher_sync_{prep,post}():  They're no longer used by
sig.c but only locally in akcipher.c.

In crypto_akcipher_sync_{prep,post}(), drop various NULL pointer checks
for data->dst as they were only necessary for the verify operation.

In the crypto_sig_*() API calls, remove the forks that were necessary
while algorithms were converted from crypto_akcipher to crypto_sig
one by one.

In struct akcipher_testvec, remove the "params", "param_len" and "algo"
elements as they were only needed for the ecrdsa verify operation.

1e562deace crypto: rsassa-pkcs1 - Migrate to sig_alg backend
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.

65c4c93caa crypto: sig - Introduce sig_alg backend
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.

beea320112 crypto: ecdsa - Drop unused test vector elements
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"

... decodes to:

    SEQUENCE (OID_id_ecPublicKey, OID_id_prime192v1)

The curve OIDs used in those "params" elements are unsurprisingly:

    OID_id_prime192v1 (2a8648ce3d030101)
    OID_id_prime256v1 (2a8648ce3d030107)
    OID_id_ansip384r1 (2b81040022)
    OID_id_ansip521r1 (2b81040023)

Those are just different names for secp192r1, secp256r1, secp384r1 and
secp521r1, respectively, per RFC 8422 appendix A:
https://www.rfc-editor.org/rfc/rfc8422#appendix-A

The entries for secp384r1 and secp521r1 curves contain a useful code
comment calling out the curve and hash.  Add analogous code comments
to secp192r1 and secp256r1 curve entries.

This reverts commit 16ab7cb582 because it
broke iwd.  iwd uses the KEYCTL_PKEY_* UAPIs via its dependency libell,
and apparently it is relying on SHA-1 signature support.  These UAPIs
are fairly obscure, and their documentation does not mention which
algorithms they support.  iwd really should be using a properly
supported userspace crypto library instead.  Regardless, since something
broke we have to revert the change.

It may be possible that some parts of this commit can be reinstated
without breaking iwd (e.g. probably the removal of MODULE_SIG_SHA1), but
for now this just does a full revert to get things working again.

16ab7cb582 crypto: pkcs7 - remove sha1 support
Removes support for sha1 signed kernel modules, importing sha1 signed
x.509 certificates.

rsa-pkcs1pad keeps sha1 padding support, which seems to be used by
virtio driver.

sha1 remains available as there are many drivers and subsystems using
it. Note only hmac(sha1) with secret keys remains cryptographically
secure.

In the kernel there are filesystems, IMA, tpm/pcr that appear to be
using sha1. Maybe they can all start to be slowly upgraded to
something else i.e. blake3, ParallelHash, SHAKE256 as needed.

ba24b8eb3e crypto: testmgr - Add some test vectors for cmac(camellia)
Add some test vectors for 128-bit cmac(camellia) as found in
draft-kato-ipsec-camellia-cmac96and128-01 section 6.2.

The document also shows vectors for camellia-cmac-96, and for VK with a
length greater than 16, but I'm not sure how to express those in testmgr.

This also leaves cts(cbc(camellia)) untested, but I can't seem to find any
tests for that that I could put into testmgr.

9d2bb9a74b crypto: testmgr - some more fixes to RSA test vectors
Two more fixes:

  * some test vectors in commit 79e6e2f3f3 ("crypto: testmgr - populate
    RSA CRT parameters in RSA test vectors") had misplaced commas, which
    break the test and trigger KASAN warnings at least on x86-64

  * pkcs1pad test vector did not have its CRT parameters

Fixes: 79e6e2f3f3 ("crypto: testmgr - populate RSA CRT parameters in RSA test vectors")

It contains ARIA ecb(aria), cbc(aria), cfb(aria), ctr(aria), and gcm(aria).
ecb testvector is from RFC standard.
cbc, cfb, and ctr testvectors are from KISA[1], who developed ARIA
algorithm.
gcm(aria) is from openssl test vector.
