"Including fixes from wireles and netfilter.
Nothing major here. Over the last two weeks we gathered only around
two-thirds of our normal weekly fix count, but delaying sending these
until -rc7 seemed like a really bad idea.
AFAIK we have no bugs under investigation. One or two reverts for
stuff for which we haven't gotten a proper fix will likely come in the
next PR.

assert that we are able to do this in a test to ensure that we do not
regress this again.

Commit 82c1f13de315 ("selftests/bpf: Add more stats into veristat")
introduced new stats, added by default in the CSV output, that were not
added to parse_stat_value, used in parse_stats_csv which is used in
comparison mode. Thus it broke comparison mode altogether making it fail
with "Unrecognized stat #7" and EINVAL.
One quirk is that PROG_TYPE and ATTACH_TYPE have been transformed to
strings using libbpf_bpf_prog_type_str and libbpf_bpf_attach_type_str
respectively. Since we might not want to compare those string values, we
just skip the parsing in this patch. We might want to translate it back
to the enum value or compare the string value directly.

The dsp_local_on selftest expects the scheduler to fail by trying to
schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't
guaranteed to happen in the 1 second window that the test is running.
Besides, it's odd to have this particular exception path tested when there
are no other tests that verify that the interface is working at all - e.g.
the test would pass if dsp_local_on interface is completely broken and fails
on any attempt.
Flip the test so that it verifies that the feature works. While at it, fix a
typo in the info message.

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular
dependency on the global-timer target due to its inclusion in
$(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency
warning during the build process.
To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been
replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change
ensures that libatest.so is built before any other targets that require it,
without creating a circular dependency.
This fix addresses the following warning:
make[4]: Entering directory 'tools/testing/selftests/alsa'
make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped.

KVM selftests "tree"-wide changes for 6.14:
- Rework vcpu_get_reg() to return a value instead of using an out-param, and
update all affected arch code accordingly.
- Convert the max_guest_memory_test into a more generic mmu_stress_test.
The basic gist of the "conversion" is to have the test do mprotect() on
guest memory while vCPUs are accessing said memory, e.g. to verify KVM
and mmu_notifiers are working as intended.
- Play nice with treewrite builds of unsupported architectures, e.g. arm
(32-bit), as KVM selftests' Makefile doesn't do anything to ensure the
target architecture is actually one KVM selftests supports.
- Use the kernel's $(ARCH) definition instead of the target triple for arch
specific directories, e.g. arm64 instead of aarch64, mainly so as not to
be different from the rest of the kernel.

Currently, LoongArch LLVM does not support the constraint "o" and no plan
to support it, it only supports the similar constraint "m", so change the

Fix the way tcpdump is executed by:
- Using the right variable for the namespace. Currently the use of the
empty "ns" makes the command fail.
- Waiting until it starts to capture to ensure the interesting traffic
is caught on slow systems.
- Using line-buffered output to ensure logs are available when the test
is paused with "-p". Otherwise the last chunk of data might only be
written when tcpdump is killed.

The sysctl tests for vm.memfd_noexec rely on the kernel to support PID
namespaces (i.e. the kernel is built with CONFIG_PID_NS=y). If the
kernel the test runs on does not support PID namespaces, the first sysctl
test will fail when attempting to spawn a new thread in a new PID
namespace, abort the test, preventing the remaining tests from being run.
This is not desirable, as not all kernels need PID namespaces, but can
still use the other features provided by memfd. Therefore, only run the
sysctl tests if the kernel supports PID namespaces. Otherwise, skip those
tests and emit an informative message to let the user know why the sysctl
tests are not being run.

Add a very simple script interpreter called "inc" that can evaluate two
different commands (one per line):
- "?" to initialize a counter from user's input;
- "+" to increment the counter (which is set to 0 by default).
It is enlighten to only interpret executable files according to
AT_EXECVE_CHECK and the related securebits:
# Executing a script with RESTRICT_FILE is only allowed if the script
# is executable:
./set-exec -f -- ./inc script-exec.inc # Allowed
./set-exec -f -- ./inc script-noexec.inc # Denied
# Executing stdin with DENY_INTERACTIVE is only allowed if stdin is an
# executable regular file:
./set-exec -i -- ./inc -i < script-exec.inc # Allowed
./set-exec -i -- ./inc -i < script-noexec.inc # Denied
# However, a pipe is not executable and it is then denied:
cat script-noexec.inc | ./set-exec -i -- ./inc -i # Denied
# Executing raw data (e.g. command argument) with DENY_INTERACTIVE is
# always denied.
./set-exec -i -- ./inc -c "+" # Denied
./inc -c "$(<script-ask.inc)" # Allowed
# To directly execute a script, we can update $PATH (used by `env`):
PATH="${PATH}:." ./script-exec.inc
# To execute several commands passed as argument:
Add a complete test suite to check the script interpreter against all
possible execution cases:

Extend the 'set_memory_region_test' with an x86-only test case which
covers emulated MMIO during event vectoring error handling. The test case
1) Sets an IDT descriptor base to point to an MMIO address
2) Generates a #GP in the guest
3) Verifies userspace gets the correct exit reason, suberror code, and
GPA in internal.data[3]
Opportunistically add a definition for a non-canonical address to
processor.h so that the source of the #GP is somewhat self-documenting,
and so that future tests don't have to reinvent the wheel.

Rework x86's KVM PV features test to align with KVM's new, fixed behavior
of not allowing userspace to disable HLT-exiting after vCPUs have been
created. Rework the core testcase to disable HLT-exiting before creating
a vCPU, and opportunistically modify keep the paired VM+vCPU creation to
verify that KVM rejects KVM_CAP_X86_DISABLE_EXITS as expected.

Actually check for KVM support for disabling HLT-exiting instead of
effectively checking that KVM_CAP_X86_DISABLE_EXITS is #defined to a
non-zero value, and convert the TEST_REQUIRE() to a simple return so
that only the sub-test is skipped if HLT-exiting is mandatory.
The goof has likely gone unnoticed because all x86 CPUs support disabling
HLT-exiting, only systems with the opt-in mitigate_smt_rsb KVM module
param disallow HLT-exiting.

Extend x86's set sregs test to verify that KVM sets/clears OSXSAVE and

Refresh selftests' CPUID cache in the vCPU structure when querying a CPUID
entry so that tests don't consume stale data when KVM modifies CPUID as a
side effect to a completely unrelated change. E.g. KVM adjusts OSXSAVE in
response to CR4.OSXSAVE changes.
Unnecessarily invoking KVM_GET_CPUID is suboptimal, but vcpu->cpuid exists
to simplify selftests development, not for performance reasons. And,
unfortunately, trying to handle the side effects in tests or other flows
is unpleasant, e.g. selftests could manually refresh if KVM_SET_SREGS is
successful, but that would still leave a gap with respect to guest CR4
changes.

Rework x86's set sregs test to verify that KVM enforces CPUID vs. CR4
features even if userspace hasn't explicitly set guest CPUID. KVM used to
allow userspace to set any KVM-supported CR4 value prior to KVM_SET_CPUID2,
and the test verified that behavior.
However, the testcase was written purely to verify KVM's existing behavior,
i.e. was NOT written to match the needs of real world VMMs.
Opportunistically verify that KVM continues to reject unsupported features
after KVM_SET_CPUID2 (using KVM_GET_SUPPORTED_CPUID).

Now that KVM selftests uses the kernel's canonical arch paths, directly
override ARCH to 'x86' when targeting x86_64 instead of defining ARCH_DIR
to redirect to appropriate paths. ARCH_DIR was originally added to deal
with KVM selftests using the target triple ARCH for directories, e.g.
s390x and aarch64; keeping it around just to deal with the one-off alias
from x86_64=>x86 is unnecessary and confusing.
Note, even when selftests are built from the top-level Makefile, ARCH is
scoped to KVM's makefiles, i.e. overriding ARCH won't trip up some other
selftests that (somehow) expects x86_64 and can't work with x86.
