After commit f7d5bcd35d ("selftests: kselftest: Mark functions that

To facilitate updating the return type of these functions, remove
'return' before the calls to ksft_exit_{pass,fail}(), as __noreturn

Just removing 'return' would have resulted in
!ret ? ksft_exit_pass() : ksft_exit_fail();

In order to facilitate debugging of issues from automated runs of the ftrace
selftests turn on verbose logging by default when run from the kselftest
runner. This is primarily used by automated systems where developers may
not have direct access to the system so defaulting to providing diagnostic
information which might help debug problems seems like a good idea.
When tests pass no extra output is generated, when they fail a full log of
the test run is provided. Since this really is rather verbose when there are
a large number of test failures or output is slow (eg, with a serial
console) this could substantially increase the run time for the tests which
might present problems with timeout detection for affected systems,
hopefully we keep the tests running well enough that this is not too much
of an issue.

The test results reported for the clone3_set_tid tests interact poorly with
automation for running kselftest since the reported test names include TIDs
dynamically allocated at runtime. A lot of automation for running kselftest
will compare runs by looking at the test name to identify if the same test
is being run so changing names make it look like the testsuite has been
updated to include new tests. This makes the results display less clearly
and breaks cases like bisection.
Address this by providing a brief description of the tests and logging that
along with the stable parameters for the test currently logged. The TIDs
are already logged separately in existing logging except for the final test
which has a new log message added. We also tweak the formatting of the
logging of expected/actual values for clarity.
There are still issues with the logging of skipped tests (many are simply
not logged at all when skipped and all are logged with different names) but
these are less disruptive since the skips are all based on not being run as
root, a condition likely to be stable for a given test system.

Currently the tty_tstamp_update test reports a different exit message
for every path it can exit via. This can be confusing for automated systems
as the string that gets logged is interpreted as a test name so if the test
status changes they can't tell that it's the same test case that was run,
they can see that the overall status of the test program is a failure but
it's not clear that it was running the same test.

which translates into the relevant report types.

a macro rather than an inline function as one might expect, none of the

"Add missing RCH support for endpoint access_coordinate calculation.
A late bug was reported by Robert Richter that the Restricted CXL Host
(RCH) support was missing in the CXL endpoint access_coordinate
calculation.
The missing support causes the topology iterator to stumble over a
NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1
support.
The fix bypasses RCH topology as the access_coordinate calculation is
not necessary since RCH does not support hotplug and the memory region
exported should be covered by the HMAT table already.
A unit test is also added to cxl_test to check against future
regressions on the topology iterator"

Robert reported the following when booting a CXL host with Restricted CXL
Host (RCH) topology:
[ 39.815379] cxl_acpi ACPI0017:00: not a cxl_port device
[ 39.827123] WARNING: CPU: 46 PID: 1754 at drivers/cxl/core/port.c:592 to_cxl_port+0x56/0x70 [cxl_core]
... plus some related subsequent NULL pointer dereference:
[ 40.718708] BUG: kernel NULL pointer dereference, address: 00000000000002d8
The iterator to walk the PCIe path did not account for RCH topology.
However RCH does not support hotplug and the memory exported by the
Restricted CXL Device (RCD) should be covered by HMAT and therefore no
access_coordinate is needed. Add check to see if the endpoint device is
RCD and skip calculation.
Also add a call to cxl_endpoint_get_perf_coordinates() in cxl_test in order
to exercise the topology iterator. The dev_is_pci() check added is to help

a page at address VSYSCALL_ADDR into the userspace program. This address
is in the top 10MB of the address space:

The last commit fixes the x86-64 BPF JIT to skip accessing addresses in
this memory region. Add this address to bpf_testmod_return_ptr() so we
can make sure that it is fixed.

The save/restore of nr_hugepages was added to the test itself by using the
atexit() functionality. But it is broken as parent exits after creating
child. Hence calling the atexit() function early. That's not it. The
child exits after creating its child and so on.
The parent cannot wait to get the termination status for its children as
it'll keep on holding the resources until the new pkey allocation fails.
It is impossible to wait for exits of all the grand and great grand
children. Hence the restoring of nr_hugepages value from parent is wrong.
Let's save/restore the nr_hugepages settings in the launch script
instead of doing it in the test.

Currently, the sud_test expects the emulated syscall to return the

were the syscall calling convention use the same register for syscall
number/syscall return value. This is not the case for RISC-V and thus
the return value must be also emulated using the provided ucontext.

Assert that accesses to a non-existent vgic-v2 CPU interface
consistently fail across the various KVM device attr ioctls. This also
serves as a regression test for a bug wherein KVM hits a NULL
dereference when the CPUID specified in the ioctl is invalid.
Note that there is no need to print the observed errno, as TEST_ASSERT()
will take care of it.

without OBJECT_FILES_NON_STANDARD. This fixes a warning
"Unpatched return thunk in use. This should not happen!" when running
KVM selftests.
* Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM
would allow userspace to refresh the cache with a bogus GPA. The bug has
existed for quite some time, but was exposed by a new sanity check added in
6.9 (to ensure a cache is either GPA-based or HVA-based).
* Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left
behind during a 6.9 cleanup.
* Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that
results in an array overflow (detected by KASAN).
* Fix a bug where KVM incorrectly clears root_role.direct when userspace sets
guest CPUID.
* Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used
by a nested guest, if KVM is using Page-Modification Logging and the nested
hypervisor is NOT using EPT.
x86 PMU:
* Drop support for virtualizing adaptive PEBS, as KVM's implementation is
architecturally broken without an obvious/easy path forward, and because
exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak
host kernel addresses to the guest.
* Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at
RESET time, as done by both Intel and AMD processors.
* Disable LBR virtualization on CPUs that don't support LBR callstacks, as
KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the
perf event, and would fail on such CPUs.
Tests:
* Fix a flaw in the max_guest_memory selftest that results in it exhausting
the supply of ucall structures when run with more than 256 vCPUs.
* Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test.

Pull kvm fixes from Paolo Bonzini:
"This is a bit on the large side, mostly due to two changes:
- Changes to disable some broken PMU virtualization (see below for
details under "x86 PMU")
- Clean up SVM's enter/exit assembly code so that it can be compiled
without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
return thunk in use. This should not happen!" when running KVM
selftests.
Everything else is small bugfixes and selftest changes:
- Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
where KVM would allow userspace to refresh the cache with a bogus
GPA. The bug has existed for quite some time, but was exposed by a
new sanity check added in 6.9 (to ensure a cache is either
GPA-based or HVA-based).
- Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
got left behind during a 6.9 cleanup.
- Fix a math goof in x86's hugepage logic for
KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
(detected by KASAN).
- Fix a bug where KVM incorrectly clears root_role.direct when
userspace sets guest CPUID.
- Fix a dirty logging bug in the where KVM fails to write-protect
SPTEs used by a nested guest, if KVM is using Page-Modification
Logging and the nested hypervisor is NOT using EPT.
x86 PMU:
- Drop support for virtualizing adaptive PEBS, as KVM's
implementation is architecturally broken without an obvious/easy
path forward, and because exposing adaptive PEBS can leak host LBRs
to the guest, i.e. can leak host kernel addresses to the guest.
- Set the enable bits for general purpose counters in
PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
processors.
- Disable LBR virtualization on CPUs that don't support LBR
callstacks, as KVM unconditionally uses
PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
would fail on such CPUs.
Tests:
- Fix a flaw in the max_guest_memory selftest that results in it
exhausting the supply of ucall structures when run with more than
256 vCPUs.
- Mark KVM_MEM_READONLY as supported for RISC-V in
set_memory_region_test"
