A missing VMCS12 was not causing -EINVAL (it was just read with
copy_from_user, so it is not a security issue, but it is still
wrong). Test for VMCS12 validity and reject the nested state
if a VMCS12 is required but not present.

Setting KVM_STATE_NESTED_GUEST_MODE enables various consistency checks
on VMCS12 and therefore causes KVM_SET_NESTED_STATE to fail spuriously
with -EINVAL. Do not set the flag so that we're sure to cover the
conditions included by the test, and cover the case where VMCS12 is
set and KVM_SET_NESTED_STATE is called with invalid VMCS12 contents.

This mirrors the original egress-only test. The cgroup_storage is
now extended to have two packet counters, one for egress and one
for ingress. We also extend to have two egress programs to test
that egress will always share with other egress origrams in the
same cgroup. The behavior of the counters are exactly the same as
the original egress-only test.
The test is split into two, one "isolated" test that when the key
type is struct bpf_cgroup_storage_key, which contains the attach
type, programs of different attach types will see different
storages. The other, "shared" test that when the key type is u64,
programs of different attach types will see the same storage if
they are attached to the same cgroup.

The current assumption is that the lifetime of a cgroup storage
is tied to the program's attachment. The storage is created in
cgroup_bpf_attach, and released upon cgroup_bpf_detach and
cgroup_bpf_release.
Because the current semantics is that each attachment gets a
completely independent cgroup storage, and you can have multiple
programs attached to the same (cgroup, attach type) pair, the key
of the CGROUP_STORAGE map, looking up the map with this pair could
yield multiple storages, and that is not permitted. Therefore,
the kernel verifier checks that two programs cannot share the same
CGROUP_STORAGE map, even if they have different expected attach
types, considering that the actual attach type does not always
have to be equal to the expected attach type.
The test creates a CGROUP_STORAGE map and make it shared across
two different programs, one cgroup_skb/egress and one /ingress.
It asserts that the two programs cannot be both loaded, due to
verifier failure from the above reason.

This test creates a parent cgroup, and a child of that cgroup.
It attaches a cgroup_skb/egress program that simply counts packets,
to a global variable (ARRAY map), and to a CGROUP_STORAGE map.
The program is first attached to the parent cgroup only, then to
parent and child.
The test cases sends a message within the child cgroup, and because
the program is inherited across parent / child cgroups, it will
trigger the egress program for both the parent and child, if they
exist. The program, when looking up a CGROUP_STORAGE map, uses the
cgroup and attach type of the attachment parameters; therefore,
both attaches uses different cgroup storages.
We assert that all packet counts returns what we expects.

Augment the existing firmware update emulation to track activations and
validate proper update vs activate sequencing.
The DIMM firmware activate capability has a concept of a maximum amount
of time platform firmware will quiesce the system relative to how many
DIMMs are being activated in parallel. Simulate that DIMM activation
happens serially, 1 second per-DIMM, and limit the max at 3 seconds. The
nfit_test0 bus emulates 5 DIMMs so it will take 2 activations to update
all DIMMs.

The UDP reuseport conflict was a little bit tricky.
The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.
At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.
This requires moving the reuseport_has_conns() logic into the callers.
While we are here, get rid of inline directives as they do not belong
in foo.c files.
The other changes were cases of more straightforward overlapping
modifications.

Existing BTF_ID_LIST used a local static variable
to store btf_ids. This patch provided a new macro
BTF_ID_LIST_GLOBAL to store btf_ids in a global
variable which can be shared among multiple files.
The existing BTF_ID_LIST is still retained.
Two reasons. First, BTF_ID_LIST is also used to build
btf_ids for helper arguments which typically
is an array of 5. Since typically different
helpers have different signature, it makes
little sense to share them. Second, some
current computed btf_ids are indeed local.
If later those btf_ids are shared between
different files, they can use BTF_ID_LIST_GLOBAL then.

ISA v3.1 does not support the SAO storage control attribute required to
implement PROT_SAO. PROT_SAO was used by specialised system software
(Lx86) that has been discontinued for about 7 years, and is not thought
to be used elsewhere, so removal should not cause problems.
We rather remove it than keep support for older processors, because
live migrating guest partitions to newer processors may not be possible
if SAO is in use (or worse allowed with silent races).
- PROT_SAO stays in the uapi header so code using it would still build.
- arch_validate_prot() is removed, the generic version rejects PROT_SAO
so applications would get a failure at mmap() time.

Extend the example program for PTP ancillary functionality with the
ability to configure not only the periodic output's period (frequency),
but also the phase and duty cycle (pulse width) which were newly
introduced.
The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2,
since the original PTP_PEROUT_REQUEST doesn't support this
functionality. For an in-tree testing program, not having explicit
backwards compatibility is fine, as it should always be tested with the
current kernel headers and sources.

Commit 01397e822af4 ("kunit: Fix TabError, remove defconfig code and
handle when there is no kunitconfig") and commit 45ba7a893ad8 ("kunit:
kunit_tool: Separate out config/build/exec/parse") introduced two
closely related issues which built off of each other: they excessively
created the build directory when not present and modified a constant
(constants in Python only exist by convention).
Together these issues broken a number of unit tests for KUnit tool, so
fix them.
Fixed up commit log to fic checkpatch commit description style error.

Commit ddbd60c779b4 ("kunit: use --build_dir=.kunit as default") changed
the default build directory for KUnit tests, but failed to update
associated unit tests for kunit_tool, so update them.

Direct stderr to subprocess.STDOUT so error messages get included in the
subprocess.CalledProcessError exceptions output field. This results in
more meaningful error messages for the user.
This is already being done in the make_allyesconfig method. Do the same
for make_mrproper, make_olddefconfig, and make methods.
With this, failures on unclean trees [1] will give users an error
message that includes:
"The source tree is not clean, please run 'make ARCH=um mrproper'"
