Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
commit 17ec3e71ba797cdb62164fea9532c81b60f47167 upstream.
The ARCH_MAY_HAVE patch missed arm64, mips and s390. But it may
also lead to arch options being enabled but ineffective because
of modular/built-in conflicts.
As the primary user of all these options wireguard is selecting
the arch options anyway, make the same selections at the lib/crypto
option level and hide the arch options from the user.
Instead of selecting them centrally from lib/crypto, simply set
the default of each arch option as suggested by Eric Biggers.
Change the Crypto API generic algorithms to select the top-level
lib/crypto options instead of the generic one as otherwise there
is no way to enable the arch options (Eric Biggers). Introduce a
set of INTERNAL options to work around dependency cycles on the
CONFIG_CRYPTO symbol.

To meet FIPS 140 requirements, add support for building a kernel module
"fips140.ko" that contains various cryptographic algorithms built from
existing kernel source files. At load time, the module checks its own
integrity and self-tests its algorithms, then registers the algorithms
with the crypto API to supersede the original algorithms provided by the
kernel itself.

The user space Jitter RNG library uses the oversampling rate of 3 which
implies that each time stamp is credited with 1/3 bit of entropy. To
obtain 256 bits of entropy, 768 time stamps need to be sampled. The
increase in OSR is applied based on a report where the Jitter RNG is
used on a system exhibiting a challenging environment to collect
entropy.
This OSR default value is now applied to the Linux kernel version of
the Jitter RNG as well.
The increase in the OSR from 1 to 3 also implies that the Jitter RNG is
now slower by default.

The SM2 algorithm has a single user in the kernel. However, it's
never been integrated properly with that user: asymmetric_keys.
The crux of the issue is that the way it computes its digest with
sm3 does not fit into the architecture of asymmetric_keys. As no
solution has been proposed, remove this algorithm.
It can be resubmitted when it is integrated properly into the
asymmetric_keys subsystem.

Remove support for the "Crypto usage statistics" feature
(CONFIG_CRYPTO_STATS). This feature does not appear to have ever been
used, and it is harmful because it significantly reduces performance and
is a large maintenance burden.
Covering each of these points in detail:
1. Feature is not being used
Since these generic crypto statistics are only readable using netlink,
it's fairly straightforward to look for programs that use them. I'm
unable to find any evidence that any such programs exist. For example,
Debian Code Search returns no hits except the kernel header and kernel
code itself and translations of the kernel header:
https://codesearch.debian.net/search?q=CRYPTOCFGA_STAT&literal=1&perpkg=1
The patch series that added this feature in 2018
(https://lore.kernel.org/linux-crypto/1537351855-16618-1-git-send-email-clabbe@baylibre.com/)
said "The goal is to have an ifconfig for crypto device." This doesn't
appear to have happened.
It's not clear that there is real demand for crypto statistics. Just
because the kernel provides other types of statistics such as I/O and
networking statistics and some people find those useful does not mean
that crypto statistics are useful too.
Further evidence that programs are not using CONFIG_CRYPTO_STATS is that
it was able to be disabled in RHEL and Fedora as a bug fix
(https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/2947).
Even further evidence comes from the fact that there are and have been
bugs in how the stats work, but they were never reported. For example,
before Linux v6.7 hash stats were double-counted in most cases.
There has also never been any documentation for this feature, so it
might be hard to use even if someone wanted to.
2. CONFIG_CRYPTO_STATS significantly reduces performance
Enabling CONFIG_CRYPTO_STATS significantly reduces the performance of
the crypto API, even if no program ever retrieves the statistics. This
primarily affects systems with a large number of CPUs. For example,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2039576 reported
that Lustre client encryption performance improved from 21.7GB/s to
48.2GB/s by disabling CONFIG_CRYPTO_STATS.
It can be argued that this means that CONFIG_CRYPTO_STATS should be
optimized with per-cpu counters similar to many of the networking
counters. But no one has done this in 5+ years. This is consistent
with the fact that the feature appears to be unused, so there seems to
be little interest in improving it as opposed to just disabling it.
It can be argued that because CONFIG_CRYPTO_STATS is off by default,
performance doesn't matter. But Linux distros tend to error on the side
of enabling options. The option is enabled in Ubuntu and Arch Linux,
and until recently was enabled in RHEL and Fedora (see above). So, even
just having the option available is harmful to users.
3. CONFIG_CRYPTO_STATS is a large maintenance burden
There are over 1000 lines of code associated with CONFIG_CRYPTO_STATS,
spread among 32 files. It significantly complicates much of the
implementation of the crypto API. After the initial submission, many
fixes and refactorings have consumed effort of multiple people to keep
this feature "working". We should be spending this effort elsewhere.

The oversampling rate used by the Jitter RNG allows the configuration of
the heuristically implied entropy in one timing measurement. This
entropy rate is (1 / OSR) bits of entropy per time stamp.
Considering that the Jitter RNG now support APT/RCT health tests for
different OSRs, allow this value to be configured at compile time to
support systems with limited amount of entropy in their timer.
The allowed range of OSR values complies with the APT/RCT cutoff health
test values which range from 1 through 15.
The default value of the OSR selection support is left at 1 which is the
current default. Thus, the addition of the configuration support does
not alter the default Jitter RNG behavior.

The memory size consumed by the Jitter RNG is one contributing factor in
the amount of entropy that is gathered. As the amount of entropy
directly correlates with the distance of the memory from the CPU, the
caches that are possibly present on a given system have an impact on the
collected entropy.
Thus, the kernel compile time should offer a means to configure the
amount of memory used by the Jitter RNG. Although this option could be
turned into a runtime option (e.g. a kernel command line option), it
should remain a compile time option as otherwise adminsitrators who may
not have performed an entropy assessment may select a value that is
inappropriate.
The default value selected by the configuration is identical to the
current Jitter RNG value. Thus, the patch should not lead to any change
in the Jitter RNG behavior.
To accommodate larger memory buffers, kvzalloc / kvfree is used.

Split out the sign/verify functionality from the existing akcipher
interface. Most algorithms in akcipher either support encryption
and decryption, or signing and verify. Only one supports both.
As a signature algorithm may not support encryption at all, these
two should be spearated.
For now sig is simply a wrapper around akcipher as all algorithms
remain unchanged. This is a first step and allows users to start
allocating sig instead of akcipher.

The test interface allows a privileged process to capture the raw
unconditioned noise that is collected by the Jitter RNG for statistical
analysis. Such testing allows the analysis how much entropy
the Jitter RNG noise source provides on a given platform. The obtained
data is the time stamp sampled by the Jitter RNG. Considering that
the Jitter RNG inserts the delta of this time stamp compared to the
immediately preceding time stamp, the obtained data needs to be
post-processed accordingly to obtain the data the Jitter RNG inserts
into its entropy pool.
The raw entropy collection is provided to obtain the raw unmodified
time stamps that are about to be added to the Jitter RNG entropy pool
and are credited with entropy. Thus, this patch adds an interface
which renders the Jitter RNG insecure. This patch is NOT INTENDED
FOR PRODUCTION SYSTEMS, but solely for development/test systems to
verify the available entropy rate.
Access to the data is given through the jent_raw_hires debugfs file.
The data buffer should be multiples of sizeof(u32) to fill the entire
buffer. Using the option jitterentropy_testing.boot_raw_hires_test=1
the raw noise of the first 1000 entropy events since boot can be
sampled.
This test interface allows generating the data required for
analysis whether the Jitter RNG is in compliance with SP800-90B
sections 3.1.3 and 3.1.4.
If the test interface is not compiled, its code is a noop which has no
impact on the performance.

Using the kernel crypto API, the SHA3-256 algorithm is used as
conditioning element to replace the LFSR in the Jitter RNG. All other
parts of the Jitter RNG are unchanged.
The application and use of the SHA-3 conditioning operation is identical
to the user space Jitter RNG 3.4.0 by applying the following concept:
- the Jitter RNG initializes a SHA-3 state which acts as the "entropy
pool" when the Jitter RNG is allocated.
- When a new time delta is obtained, it is inserted into the "entropy
pool" with a SHA-3 update operation. Note, this operation in most of
the cases is a simple memcpy() onto the SHA-3 stack.
- To cause a true SHA-3 operation for each time delta operation, a
second SHA-3 operation is performed hashing Jitter RNG status
information. The final message digest is also inserted into the
"entropy pool" with a SHA-3 update operation. Yet, this data is not
considered to provide any entropy, but it shall stir the entropy pool.
- To generate a random number, a SHA-3 final operation is performed to
calculate a message digest followed by an immediate SHA-3 init to
re-initialize the "entropy pool". The obtained message digest is one
block of the Jitter RNG that is returned to the caller.
Mathematically speaking, the random number generated by the Jitter RNG
is:
aux_t = SHA-3(Jitter RNG state data)
Jitter RNG block = SHA-3(time_i || aux_i || time_(i-1) || aux_(i-1) ||
... || time_(i-255) || aux_(i-255))
when assuming that the OSR = 1, i.e. the default value.
This operation implies that the Jitter RNG has an output-blocksize of
256 bits instead of the 64 bits of the LFSR-based Jitter RNG that is
replaced with this patch.
The patch also replaces the varying number of invocations of the
conditioning function with one fixed number of invocations. The use
of the conditioning function consistent with the userspace Jitter RNG
library version 3.4.0.
The code is tested with a system that exhibited the least amount of
entropy generated by the Jitter RNG: the SiFive Unmatched RISC-V
system. The measured entropy rate is well above the heuristically
implied entropy value of 1 bit of entropy per time delta. On all other
tested systems, the measured entropy rate is even higher by orders
of magnitude. The measurement was performed using updated tooling
provided with the user space Jitter RNG library test framework.
The performance of the Jitter RNG with this patch is about en par
with the performance of the Jitter RNG without the patch.

With a blatant copy of some MIPS bits we introduce the crc32 and crc32c

LoongArch has provided these instructions to calculate crc32 and crc32c:
* crc.w.b.w crcc.w.b.w
* crc.w.h.w crcc.w.h.w
* crc.w.w.w crcc.w.w.w
* crc.w.d.w crcc.w.d.w
So we can make use of these instructions to improve the performance of
calculation for crc32(c) checksums.
As can be seen from the following test results, crc32(c) instructions
can improve the performance by 58%.

Commit 2d16803c56 ("crypto: blake2s - remove shash module") removes the
config CRYPTO_BLAKE2S.
Commit 3f342a2325 ("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.

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.

As requested at
https://lore.kernel.org/r/YtEgzHuuMts0YBCz@gondor.apana.org.au, move
__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.

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.
v4: return utsrelease.h inclusion

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.

Various accelerated software implementation Kconfig values for S390 were
mistakenly placed into drivers/crypto/Kconfig, even though they're
mainly just SIMD code and live in arch/s390/crypto/ like usual. This
gives them the very unusual dependency on CRYPTO_HW, which leads to
problems elsewhere.
This patch fixes the issue by moving the Kconfig values for non-hardware
drivers into the usual place in crypto/Kconfig.
