Pull random number generator fixes from Jason Donenfeld:
- A fix for a 5.19 regression for a case in which early device tree
initializes the RNG, which flips a static branch.
On most plaforms, jump labels aren't initialized until much later, so
this caused splats. On a few mailing list threads, we cooked up easy
fixes for arm64, arm32, and risc-v. But then things looked slightly
more involved for xtensa, powerpc, arc, and mips. And at that point,
when we're patching 7 architectures in a place before the console is
even available, it seems like the cost/risk just wasn't worth it.
So random.c works around it now by checking the already exported
`static_key_initialized` boolean, as though somebody already ran into
this issue in the past. I'm not super jazzed about that; it'd be
prettier to not have to complicate downstream code. But I suppose
it's practical.
- A few small code nits and adding a missing __init annotation.
- A change to the default config values to use the cpu and bootloader's
seeds for initializing the RNG earlier.
This brings them into line with what all the distros do (Fedora/RHEL,
Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
least), and moreover will now give us test coverage in various test
beds that might have caught the above device tree bug earlier.
- A change to WireGuard CI's configuration to increase test coverage
around the RNG.
- A documentation comment fix to unrelated maintainerless CRC code that
I was asked to take, I guess because it has to do with polynomials
(which the RNG thankfully no longer uses).

By forcing the maximum CPU that QEMU has available, we expose additional
capabilities, such as the RNDR instruction, which increases test
coverage. This then allows the CI to skip the fake seeding step in some
cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
jump labels when the RNG is initialized at boot.

When no l3 address is given, priv->family is set to NFPROTO_INET and
the evaluation function isn't called.
Call it too so l4-only rewrite can work.
Also add a test case for this.

hyperv_clock doesn't always give a stable test result, especially with
AMD CPUs. The test compares Hyper-V MSR clocksource (acquired either
with rdmsr() from within the guest or KVM_GET_MSRS from the host)
against rdtsc(). To increase the accuracy, increase the measured delay
(done with nop loop) by two orders of magnitude and take the mean rdtsc()
value before and after rdmsr()/KVM_GET_MSRS.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the set of driver core changes for 5.19-rc1.
Lots of tiny driver core changes and cleanups happened this cycle, but
the two major things are:
- firmware_loader reorganization and additions including the ability
to have XZ compressed firmware images and the ability for userspace
to initiate the firmware load when it needs to, instead of being
always initiated by the kernel. FPGA devices specifically want this
ability to have their firmware changed over the lifetime of the
system boot, and this allows them to work without having to come up
with yet-another-custom-uapi interface for loading firmware for
them.
- physical location support added to sysfs so that devices that know
this information, can tell userspace where they are located in a
common way. Some ACPI devices already support this today, and more
bus types should support this in the future.
Smaller changes include:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten
any linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time-outs"

It's similar like XZ compressed files. For the simplicity, both XZ
and ZSTD tests are done in a single function. The format is specified
via $COMPRESS_FORMAT and the compression function is pre-defined.

the XZ compressed file tests.

The xz -9 option leads to an unnecessarily too large dictionary that
isn't really suitable for the kernel firmware loader. Pass the
dictionary size explicitly, instead.
While we're at it, make the xz command call defined in $RUN_XZ for
simplicity.

Pull char / misc / other smaller driver subsystem updates from Greg KH:
"Here is the large set of char, misc, and other driver subsystem
updates for 5.19-rc1. The merge request for this has been delayed as I
wanted to get lots of linux-next testing due to some late arrivals of
changes for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers and
cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no
reported problems"

In order to test various backward-edge control flow integrity methods,
add a test that manipulates the return address on the stack. Currently
only arm64 Pointer Authentication and Shadow Call Stack is supported.
$ echo CFI_BACKWARD | cat >/sys/kernel/debug/provoke-crash/DIRECT
Under SCS, successful test of the mitigation is reported as:
lkdtm: Performing direct entry CFI_BACKWARD
lkdtm: Attempting unchecked stack return address redirection ...
lkdtm: ok: redirected stack return address.
lkdtm: Attempting checked stack return address redirection ...
lkdtm: ok: control flow unchanged.
Under PAC, successful test of the mitigation is reported by the PAC
exception handler:
lkdtm: Performing direct entry CFI_BACKWARD
lkdtm: Attempting unchecked stack return address redirection ...
lkdtm: ok: redirected stack return address.
lkdtm: Attempting checked stack return address redirection ...

FSC = 0x04: level 0 translation fault

Follow the pattern used by other selftests like memfd and fall back on the
standard toolchain options to build with a system installed alsa-lib if
we don't get anything from pkg-config. This reduces our build dependencies
a bit in the common case while still allowing use of pkg-config in case
there is a need for it.

RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

The psock_snd test sends and receives packets over loopback, and
the test results depend on parameter settings:
Set rp_filter=0,
or set rp_filter=1 and accept_local=1
so that the test will pass. Otherwise, this test will fail with
Resource temporarily unavailable:
sudo ./psock_snd.sh
dgram
tx: 128
rx: 142
./psock_snd: recv: Resource temporarily unavailable
For most distro kernel releases(like Ubuntu or Centos), the parameter
rp_filter is enabled by default, so it's necessary to enable the
parameter lo.accept_local in psock_snd test. And this test runs
inside a netns, changing a sysctl is fine.

It may lead to kernel panic when execute the following testcase on mips:
# cd tools/testing/selftests/ftrace
# ./ftracetest test.d/kprobe/multiple_kprobes.tc
A preliminary analysis shows that the issue is related with
echo 1 > events/kprobes/enable
after add the 256 probe points.
In order to find the root cause, I want to verify which probe point has
problem, so it is necessary to save kprobe_events to test log.
With this patch, we can get the 256 probe points in the test log through
the following command:
# ./ftracetest test.d/kprobe/multiple_kprobes.tc -vvv -k

Commit 3752e453f6ba ("selftests/powerpc: Add tests of PMU EBBs") added
selftest testcases to verify EBB interface. instruction_count_test.c
testcase needs a fixed loop function to count overhead. Instead of using
the thirty_two_instruction_loop() in fixed_instruction_loop.S in ebb
folder, file is linked with thirty_two_instruction_loop() in loop.S from
top folder. Since fixed_instruction_loop.S not used, patch removes the
file.

In commit f3054ffd71b5 ("selftests/powerpc: Return skip code for
spectre_v2"), the spectre_v2 selftest is updated to be aware of cases
where the vulnerability status reported in sysfs is incorrect, skipping
the test instead.
This happens because qemu can misrepresent the mitigation status of the
host to the guest. If the count cache is disabled in the host, and this
is correctly reported to the guest, then the guest won't apply
mitigations. If the guest is then migrated to a new host where
mitigations are necessary, it is now vulnerable because it has not
applied mitigations.
Update the selftest to report when we see excessive misses, indicative of
the count cache being disabled. If software flushing is enabled, also
warn that these flushes are just wasting performance.
