Pull MM updates from Andrew Morton:
- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any
negative reports (or any positive ones, come to that).
- Also the Maple Tree from Liam Howlett. An overlapping range-based
tree for vmas. It it apparently slightly more efficient in its own
right, but is mainly targeted at enabling work to reduce mmap_lock
contention.
Liam has identified a number of other tree users in the kernel which
could be beneficially onverted to mapletrees.
Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
at [1]. This has yet to be addressed due to Liam's unfortunately
timed vacation. He is now back and we'll get this fixed up.
- Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
clang-generated instrumentation to detect used-unintialized bugs down
to the single bit level.
KMSAN keeps finding bugs. New ones, as well as the legacy ones.
- Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
memory into THPs.
- Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
support file/shmem-backed pages.
- userfaultfd updates from Axel Rasmussen
- zsmalloc cleanups from Alexey Romanov
- cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
memory-failure
- Huang Ying adds enhancements to NUMA balancing memory tiering mode's
page promotion, with a new way of detecting hot pages.
- memcg updates from Shakeel Butt: charging optimizations and reduced
memory consumption.
- memcg cleanups from Kairui Song.
- memcg fixes and cleanups from Johannes Weiner.
- Vishal Moola provides more folio conversions
- Zhang Yi removed ll_rw_block() :(
- migration enhancements from Peter Xu
- migration error-path bugfixes from Huang Ying
- Aneesh Kumar added ability for a device driver to alter the memory
tiering promotion paths. For optimizations by PMEM drivers, DRM
drivers, etc.
- vma merging improvements from Jakub Matěn.
- NUMA hinting cleanups from David Hildenbrand.
- xu xin added aditional userspace visibility into KSM merging
activity.
- THP & KSM code consolidation from Qi Zheng.
- more folio work from Matthew Wilcox.
- KASAN updates from Andrey Konovalov.
- DAMON cleanups from Kaixu Xia.
- DAMON work from SeongJae Park: fixes, cleanups.
- hugetlb sysfs cleanups from Muchun Song.
- Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.

Commit 2d16803c562e ("crypto: blake2s - remove shash module") removes the
config CRYPTO_BLAKE2S.
Commit 3f342a23257d ("crypto: Kconfig - simplify hash entries") makes
various changes to the config descriptions as part of some consolidation
and clean-up, but among all those changes, it also accidently adds back
CRYPTO_BLAKE2S after its removal due to the original patch being based on
a state before the CRYPTO_BLAKE2S removal.
See Link for the author's confirmation of this happening accidently.

Changes from v1:
* removed the default implementation from set_pub_key: it is assumed that
an implementation must always have this callback defined as there are
no use case for an algorithm, which doesn't need a public key
Many akcipher implementations (like ECDSA) support only signature
verifications, so they don't have all callbacks defined.
Commit 78a0324f4a53 ("crypto: akcipher - default implementations for
request callbacks") introduced default callbacks for sign/verify
operations, which just return an error code.
However, these are not enough, because before calling sign the caller would
likely call set_priv_key first on the instantiated transform (as the
in-kernel testmgr does). This function does not have a default stub, so the
kernel crashes, when trying to set a private key on an akcipher, which
doesn't support signature generation.
I've noticed this, when trying to add a KAT vector for ECDSA signature to
the testmgr.
With this patch the testmgr returns an error in dmesg (as it should)
instead of crashing the kernel NULL ptr dereference.
Fixes: 78a0324f4a53 ("crypto: akcipher - default implementations for request callbacks")

Convert each comment section into a submenu:
Cryptographic API
Crypto core or helper
Public-key cryptography
Block ciphers
Length-preserving ciphers and modes
AEAD (authenticated encryption with associated data) ciphers
Hashes, digests, and MACs
CRCs (cyclic redundancy checks)
Compression
Random number generation
Userspace interface
That helps find entries (e.g., searching for a name like SHA512 doesn't
just report the location is Main menu -> Cryptography API, leaving you
to wade through 153 entries; it points you to the Digests page).
Move entries so they fall into the correct submenus and are
better sorted.

The lists of algothms checked for existence by
modprobe tcrypt mode=1000
generates three bogus errors:
modprobe tcrypt mode=1000
console log:
tcrypt: alg rot13 not found
tcrypt: alg cts not found
tcrypt: alg arc4 not found
rot13 is not an algorithm in the crypto API or tested.
cts is a wrapper, not a base algorithm.
arc4 is named ecb(arc4), not arc4.
Also, the list is missing numerous algorithms that are tested by
other test modes:
blake2b-512
blake2s-256
crct10dif
xxhash64
ghash
cast5
sm4
ansi_prng
Several of the algorithms are only available if
CONFIG_CRYPTO_USER_API_ENABLE_OBSOLETE is enabled:
arc4
khazad
seed
tea, xtea, xeta
Rather that fix that list, remove test mode=1000 entirely.
It seems to have limited utility, and a web search shows no
discussion of anybody using it.

This userspace command:
modprobe tcrypt
or
modprobe tcrypt mode=0
runs all the tcrypt test cases numbered <200 (i.e., all the
test cases calling tcrypt_test() and returning return values).
Tests are sparsely numbered from 0 to 1000. For example:
modprobe tcrypt mode=12
tests sha512, and
modprobe tcrypt mode=152
tests rfc4543(gcm(aes))) - AES-GCM as GMAC
The test manager generates WARNING crashdumps every time it attempts
a test using an algorithm that is not available (not built-in to the
kernel or available as a module):
alg: skcipher: failed to allocate transform for ecb(arc4): -2
------------[ cut here ]-----------
alg: self-tests for ecb(arc4) (ecb(arc4)) failed (rc=-2)
WARNING: CPU: 9 PID: 4618 at crypto/testmgr.c:5777
alg_test+0x30b/0x510
[50 more lines....]
---[ end trace 0000000000000000 ]---
If the kernel is compiled with CRYPTO_USER_API_ENABLE_OBSOLETE
disabled (the default), then these algorithms are not compiled into
the kernel or made into modules and trigger WARNINGs:
arc4 tea xtea khazad anubis xeta seed
Additionally, any other algorithms that are not enabled in .config
will generate WARNINGs. In RHEL 9.0, for example, the default
selection of algorithms leads to 16 WARNING dumps.
One attempt to fix this was by modifying tcrypt_test() to check
crypto_has_alg() and immediately return 0 if crypto_has_alg() fails,
rather than proceed and return a non-zero error value that causes
the caller (alg_test() in crypto/testmgr.c) to invoke WARN().
That knocks out too many algorithms, though; some combinations
like ctr(des3_ede) would work.
Instead, change the condition on the WARN to ignore a return
value is ENOENT, which is the value returned when the algorithm
or combination of algorithms doesn't exist. Add a pr_warn to
communicate that information in case the WARN is skipped.
This approach allows algorithm tests to work that are combinations,
not provided by one driver, like ctr(blowfish).
Result - no more WARNINGs:
modprobe tcrypt

CRYPTO_LIB_CHACHA depends on CRYPTO for __crypto_xor, defined in
crypto/algapi.c. This is a layering violation because the dependencies
should only go in the other direction (crypto/ => lib/crypto/). Also
the correct dependency would be CRYPTO_ALGAPI, not CRYPTO. Fix this by
moving __crypto_xor into the utils module in lib/crypto/.
Note that CRYPTO_LIB_CHACHA_GENERIC selected XOR_BLOCKS, which is
unrelated and unnecessary. It was perhaps thought that XOR_BLOCKS was
needed for __crypto_xor, but that's not the case.

__crypto_memneq into lib/crypto/ and put it under a new tristate. The
tristate is CRYPTO_LIB_UTILS, and it builds a module libcryptoutils. As
more crypto library utilities are being added, this creates a single
place for them to go without cluttering up the main lib directory.
The module's main file will be lib/crypto/utils.c. However, leave
memneq.c as its own file because of its nonstandard license.

It turns out that gcc-12.1 has some nasty problems with register
allocation on a 32-bit x86 build for the 64-bit values used in the
generic blake2b implementation, where the pattern of 64-bit rotates and
xor operations ends up making gcc generate horrible code.
As a result it ends up with a ridiculously large stack frame for all the
spills it generates, resulting in the following build problem:
crypto/blake2b_generic.c: In function ‘blake2b_compress_one_generic’:
crypto/blake2b_generic.c:109:1: error: the frame size of 2640 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
on the same test-case, clang ends up generating a stack frame that is
just 296 bytes (and older gcc versions generate a slightly bigger one at
428 bytes - still nowhere near that almost 3kB monster stack frame of
gcc-12.1).
The issue is fixed both in mainline and the GCC 12 release branch [1],
but current release compilers end up failing the i386 allmodconfig build
due to this issue.
Disable the warning for now by simply raising the frame size for this
one file, just to keep this issue from having people turn off WERROR.

The signature verification of SM2 needs to add the Za value and
recalculate sig->digest, which requires the detection of the pkey_algo
in public_key_verify_signature(). As Eric Biggers said, the pkey_algo
field in sig is attacker-controlled and should be use pkey->pkey_algo
instead of sig->pkey_algo, and secondly, if sig->pkey_algo is NULL, it
will also cause signature verification failure.
The software_key_determine_akcipher() already forces the algorithms
are matched, so the SM3 algorithm is enforced in the SM2 signature,
although this has been checked, we still avoid using any algorithm
information in the signature as input.

Since the Linux RNG no longer uses sha1_transform(), the SHA-1 library
is no longer needed unconditionally. Make it possible to build the
Linux kernel without the SHA-1 library by putting it behind a kconfig
option, and selecting this new option from the kconfig options that gate
the remaining users: CRYPTO_SHA1 for crypto/sha1_generic.c, BPF for
kernel/bpf/core.c, and IPV6 for net/ipv6/addrconf.c.
Unfortunately, since BPF is selected by NET, for now this can only make
a difference for kernels built without networking support.

FIPS 140-3 introduced a requirement for the FIPS module to return
information about itself, specifically a name and a version. These
values must match the values reported on FIPS certificates.
This patch adds two files to read a name and a version from:
/proc/sys/crypto/fips_name
/proc/sys/crypto/fips_version
v2: removed redundant parentheses in config entries.
v3: move FIPS_MODULE_* defines to fips.c where they are used.

ARIA(RFC 5794) is a symmetric block cipher algorithm.
This algorithm is being used widely in South Korea as a standard cipher
algorithm.
This code is written based on the ARIA implementation of OpenSSL.
The OpenSSL code is based on the distributed source code[1] by KISA.
ARIA has three key sizes and corresponding rounds.
ARIA128: 12 rounds.
ARIA192: 14 rounds.
ARIA245: 16 rounds.
