crypto: ccp - Initialize PSP when reading psp data file failed
Currently the OS fails the PSP initialization when the file specified at
'init_ex_path' does not exist or has invalid content. However the SEV
spec just requires users to allocate 32KB of 0xFF in the file, which can
be taken care of by the OS easily.
To improve the robustness during the PSP init, leverage the retry
mechanism and continue the init process:
Before the first INIT_EX call, if the content is invalid or missing,
continue the process by feeding those contents into PSP instead of
aborting. PSP will then override it with 32KB 0xFF and return
SEV_RET_SECURE_DATA_INVALID status code. In the second INIT_EX call,
this 32KB 0xFF content will then be fed and PSP will write the valid
data to the file.
In order to do this, sev_read_init_ex_file should only be called once
for the first INIT_EX call. Calling it again for the second INIT_EX call
will cause the invalid file content overwriting the valid 32KB 0xFF data
provided by PSP in the first INIT_EX call.

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:

A quirk for fixing the committed TCB version, when upgrading from a

Currently, this issue requires the following workaround:
sudo modprobe -r kvm_amd
sudo modprobe -r ccp

sudo modprobe kvm_amd
Implement this workaround inside kernel by checking whether the API

crypto: keembay-ocs - Drop obsolete dependency on COMPILE_TEST
Since commit
0166dc11be91 ("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.

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.

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.

perf jevents: Fold strings optimization
If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.
In pmu-events.c this looks like the following where the 'also:' lists
folded strings:
/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */
As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

perf jevents: Compress the pmu_events_table
The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).
The file size savings are:
no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.
For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.
To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.
To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

perf pmu-events: Don't assume pmu_event is an array
The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.
This makes it difficult to refactor pmu_event.
Add a loop function taking a callback function that's passed the struct
pmu_event.
This way the pmu_event is only needed for one element and not an entire
array.
Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.
