6363d81b78 crypto: tcrypt - remove mode=1000
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.

874b301985 crypto: lib - remove unneeded selection of XOR_BLOCKS
CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS.  It perhaps
was thought that it's needed for __crypto_xor, but that's not the case.

Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a
benchmark when it is initialized.  That causes a boot time regression on
systems that didn't have it enabled before.

Therefore, remove this unnecessary and problematic selection.

a76bd86a85 crypto: testmgr - don't generate WARN for missing modules
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

aa031b8f70 crypto: x86/sha512 - load based on CPU features
x86 optimized crypto modules built as modules rather than built-in
to the kernel end up as .ko files in the filesystem, e.g., in
/usr/lib/modules. If the filesystem itself is a module, these might
not be available when the crypto API is initialized, resulting in
the generic implementation being used (e.g., sha512_transform rather
than sha512_transform_avx2).

In one test case, CPU utilization in the sha512 function dropped
from 15.34% to 7.18% after forcing loading of the optimized module.

Add module aliases for this x86 optimized crypto module based on CPU
feature bits so udev gets a chance to load them later in the boot
process when the filesystems are all running.

b3b9fdf1a9 crypto: ccp - Add a quirk to firmware update
A quirk for fixing the committed TCB version, when upgrading from a
firmware version earlier than 1.50. This is a known issue, and the
documented workaround is to load the firmware twice.

Currently, this issue requires the  following workaround:

sudo modprobe -r kvm_amd
sudo modprobe -r ccp
sudo modprobe ccp
sudo modprobe kvm_amd

Implement this workaround inside kernel by checking whether the API
version is less than 1.50, and if so, download the firmware twice.
This addresses the TCB version issue.

56fae4304c crypto: keembay-ocs - Drop obsolete dependency on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

36cb649442 hwrng: core - let sleep be interrupted when unregistering hwrng
There are two deadlock scenarios that need addressing, which cause
problems when the computer goes to sleep, the interface is set down, and
hwrng_unregister() is called. When the deadlock is hit, sleep is delayed
for tens of seconds, causing it to fail. These scenarios are:

1) The hwrng kthread can't be stopped while it's sleeping, because it
   uses msleep_interruptible() which does not react to kthread_stop.

2) A normal user thread can't be interrupted by hwrng_unregister() while
   it's sleeping, because hwrng_unregister() is called from elsewhere.

We solve both issues by add a completion object called dying that
fulfils waiters once we have started the process in hwrng_unregister.

At the same time, we should cleanup a common and useless dmesg splat
in the same area.

- Type of binary image (MMP or AE Firmware)

Firmware binaries use RSA3K for signing and verification.
The header length for the RSA3k is 0x384 bytes.

as DWORDS (1 DWORD = 4bytes).

On an invalid value the function prints an error message and returns

96f86ff083 perf tools changes for v6.0: 2nd batch
- 'perf c2c' now supports ARM64, adjust its output to cope with differences with
   what is in x86_64. Now go find false sharing on ARM64 (at least Neoverse) as well!
 
 - Refactor the JSON processing, making the output more compact and thus reducing the
   size of the resulting perf binary.
 
 - Improvements for 'perf offcpu' profiling, including tracking child processes.
 
 - Update Intel JSON metrics and events files for broadwellde, broadwellx,
   cascadelakex, haswellx, icelakex, ivytown, jaketown, knightslanding,
   sapphirerapids, skylakex and snowridgex.
 
 - Add 'perf stat' JSON output and a 'perf test' entry for it.
 
 - Ignore memfd and anonymous mmap events if jitdump present.
 
 - Refactor 'perf test' shell tests allowing subdirs.
 
 - Fix an error handling path in 'parse_perf_probe_command()'
 
 - Fixes for the guest Intel PT tracing patchkit in the 1st batch of this merge window.
 
 - Print debuginfod queries if -v option is used, to explain delays in processing when
   debuginfo servers are enabled to fetch DSOs with richer symbol tables.
 
 - Improve error message for 'perf record -p not_existing_pid'
 
 - Fix openssl and libbpf feature detection.
 
 - Add PMU pai_crypto event description for IBM z16 on 'perf list'.
 
 - Fix typos and duplicated words on comments in various places.

8549a26308 afs: Enable multipage folio support
Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

7391db6459 perf test: Refactor shell tests allowing subdirs
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.
