selftests: test_bridge_neigh_suppress.sh: Fix failures due to duplicate MAC
When creating the topology for the test, three veth pairs are created in
the initial network namespace before being moved to one of the network
namespaces created by the test.
On systems where systemd-udev uses MACAddressPolicy=persistent (default
since systemd version 242), this will result in some net devices having
the same MAC address since they were created with the same name in the
initial network namespace. In turn, this leads to arping / ndisc6
failing since packets are dropped by the bridge's loopback filter.
Fix by creating each net device in the correct network namespace instead
of moving it there from the initial network namespace.

selftests/vDSO: fix runtime errors on LoongArch
It could not find __vdso_getcpu and __vdso_gettimeofday when test getcpu
and gettimeofday on LoongArch.
# make headers && cd tools/testing/selftests/vDSO && make
# ./vdso_test_getcpu
Could not find __vdso_getcpu
# ./vdso_test_gettimeofday
Could not find __vdso_gettimeofday
One simple way is to add LoongArch case to define version and name, just
like commit

selftests/vDSO: fix building errors on LoongArch
Patch series "selftests/vDSO: Fix errors on LoongArch", v4.
This patch (of 2):
There exist the following errors when build vDSO selftests on LoongArch:
# make headers && cd tools/testing/selftests/vDSO && make
...
error: 'VDSO_VERSION' undeclared (first use in this function)
...
error: 'VDSO_NAMES' undeclared (first use in this function)
We can see the following code in arch/loongarch/vdso/vdso.lds.S:
VERSION
{
LINUX_5.10 {
global:
__vdso_getcpu;
__vdso_clock_getres;
__vdso_clock_gettime;
__vdso_gettimeofday;
__vdso_rt_sigreturn;
local: *;
};
}
so VDSO_VERSION should be 6 and VDSO_NAMES should be 1 for LoongArch,
add them to fix the building errors on LoongArch.

tools: fix userspace compilation with new test_xarray changes
Patch series "test_xarray: couple of fixes for v6-9-rc6", v2.
Here are a couple of fixes which should be merged into the queue for
v6.9-rc6. The first one was reported by Liam, after fixing that I noticed
an issue with a test, and a fix for that is in the second patch.
This patch (of 2):
Liam reported that compiling the test_xarray on userspace was broken. I
was not even aware that was possible but you can via and you can run these
tests in userspace with:
make -C tools/testing/radix-tree
./tools/testing/radix-tree/xarray
Add the two helpers we need to fix compilation. We don't need a userspace
schedule() so just make it do nothing.

cxl: Fix cxl_endpoint_get_perf_coordinate() support for RCH
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
with this test and should be harmless for normal operation.

selftests/bpf: Test PROBE_MEM of VSYSCALL_ADDR on x86-64
The vsyscall is a legacy API for fast execution of system calls. It maps a page at address VSYSCALL_ADDR into the userspace program. This address is in the top 10MB of the address space: ffffffffff600000 - ffffffffff600fff | 4 kB | legacy vsyscall ABI 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. After this change and without the previous commit, subprogs_extable selftest will crash the kernel.

selftests: mm: protection_keys: save/restore nr_hugepages value from launch script
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.

selftests: sud_test: return correct emulated syscall value on RISC-V
Currently, the sud_test expects the emulated syscall to return the emulated syscall number. This assumption only works on architectures 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.

* 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.
* 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.

selftests/tcp_ao: Make RST tests less flaky
Currently, "active reset" cases are flaky, because select() is called
for 3 sockets, while only 2 are expected to receive RST.
The idea of the third socket was to get into request_sock_queue,
but the test mistakenly attempted to connect() after the listener
socket was shut down.
Repair this test, it's important to check the different kernel
code-paths for signing RST TCP-AO segments.

KVM: selftests: Add coverage of EPT-disabled to vmx_dirty_log_test
Extend vmx_dirty_log_test to include accesses made by L2 when EPT is
disabled.
This commit adds explicit coverage of a bug caught by syzkaller, where
the TDP MMU would clear D-bits instead of write-protecting SPTEs being
used to map an L2, which only happens when L1 does not enable EPT,
causing writes made by L2 to not be reflected in the dirty log when PML
is enabled:
$ ./vmx_dirty_log_test
Nested EPT: disabled
==== Test Assertion Failure ====
x86_64/vmx_dirty_log_test.c:151: test_bit(0, bmap)
pid=72052 tid=72052 errno=4 - Interrupted system call
(stack trace empty)
Page 0 incorrectly reported clean
Opportunistically replace the volatile casts with {READ,WRITE}_ONCE().
