Patch set [1] introduced BTF_KIND_TAG to allow tagging
declarations for struct/union, struct/union field, var, func
and func arguments and these tags will be encoded into
dwarf. They are also encoded to btf by llvm for the bpf target.
After BTF_KIND_TAG is introduced, we intended to use it
for kernel __user attributes. But kernel __user is actually
a type attribute. Upstream and internal discussion showed
it is not a good idea to mix declaration attribute and
type attribute. So we proposed to introduce btf_type_tag
as a type attribute and existing btf_tag renamed to
btf_decl_tag ([2]).
This patch renamed BTF_KIND_TAG to BTF_KIND_DECL_TAG and some
other declarations with *_tag to *_decl_tag to make it clear
the tag is for declaration. In the future, BTF_KIND_TYPE_TAG
might be introduced per [3].

Since the timer stack (hardware and KVM) is per-CPU, there
are potential chances for races to occur when the scheduler
decides to migrate a vCPU thread to a different physical CPU.
Hence, include an option to stress-test this part as well by
forcing the vCPUs to migrate across physical CPUs in the
system at a particular rate.
Originally, the bug for the fix with commit 3134cc8beb69d0d
("KVM: arm64: vgic: Resample HW pending state on deactivation")
was discovered using arch_timer test with vCPU migrations and
can be easily reproduced.

to get the vcpuid that it's running on to pull the per-cpu private

independent, but defined only for arm64 as of now.

With the inclusion of sysreg.h, that brings in system register
encodings, it would be redundant to re-define register encodings
again in processor.h to use it with ARM64_SYS_REG for the KVM

ARM64_SYS_KVM_REG, that converts SYS_* definitions in sysreg.h
into ARM64_SYS_REG definitions.
Also replace all the users of ARM64_SYS_REG, relying on
the encodings created in processor.h, with ARM64_SYS_KVM_REG and

The current default does not allowing additional subflows, mostly
as a safety restriction to avoid uncontrolled resource consumption
on busy servers.
Still the system admin and/or the application have to opt-in to
MPTCP explicitly. After that, they need to change (increase) the
default maximum number of additional subflows.
Let set that to reasonable default, and make end-users life easier.
Additionally we need to update some self-tests accordingly.

In `test_no_sockets` we don't expect any sockets, indeed
check_no_sockets() prints an error and exits if `sockets` list is
not empty, so free_sock_stat() call is unnecessary since it would
only be called when the `sockets` list is empty.
This was discovered by a strange warning printed by gcc v11.2.1:
In file included from ../../include/linux/list.h:7,
from vsock_diag_test.c:18:
vsock_diag_test.c: In function ‘test_no_sockets’:
../../include/linux/kernel.h:35:45: error: array subscript ‘struct vsock_stat[0]’ is partly outside array bound
s of ‘struct list_head[1]’ [-Werror=array-bounds]

| ^~~~~~~
../../include/linux/list.h:23:26: note: in definition of macro ‘LIST_HEAD’
23 | struct list_head name = LIST_HEAD_INIT(name)
It seems related to some compiler optimization and assumption
about the empty `sockets` list, since this warning is printed
only with -02 or -O3. Also removing `exit(1)` from
check_no_sockets() makes the warning disappear since in that
case free_sock_stat() can be reached also when the list is
not empty.

Test that applications binding listening sockets to VRFs without

l3index. See this email:

Applications using tcp_l3mdev_accept=1 and a single global socket (not
bound to any interface) also should have a way to specify keys that are
only for the default VRF, this is done by --force-bind-key-ifindex
without otherwise binding to a device.

Add do_mark_test(), which is to do_ecn_test() like do_drop_test() is to
do_red_test(): meant to test that actions on the RED mark qevent block are
offloaded, and executed on ECN-marked packets.
The test splits install_qdisc() into its constituents, install_root_qdisc()
and install_qdisc_tcX(). This is in order to test that when mirroring is
enabled on one TC, the other TC does not mirror.

This KUnit fixes update for Linux 5.15-rc6 consists of:
- Fixes to address the structleak plugin causing the stack frame size
to grow immensely when used with KUnit. Fixes include adding a new
makefile to disable structleak and using it from KUnit iio, device
property, thunderbolt, and bitfield tests to disable it.
- KUnit framework reference count leak in kfree_at_end
- KUnit tool fix to resolve conflict between --json and --raw_output
and generate correct test output in either case.
- kernel-doc warnings due to mismatched arg names

Add a test case that demonstrates port shadowing via UDP.
ns2 sends packet to ns1, from source port used by a udp service on the
router, ns0. Then, ns1 sends packet to ns0:service, but that ends up getting
forwarded to ns2.
Also add three test cases that demonstrate mitigations:
1. disable use of $port as source from 'unstrusted' origin
2. make the service untracked. This prevents masquerade entries
from having any effects.
3. add forced PAT via 'random' mode to translate the "wrong" sport
into an acceptable range.

Add a new test into vgic_init which checks that the first vcpu fails to
run if there is not sufficient REDIST space below the addressable IPA
range. This only applies to the KVM_VGIC_V3_ADDR_TYPE_REDIST legacy API
as the required REDIST space is not know when setting the DIST region.
Note that using the REDIST_REGION API results in a different check at
first vcpu run: that the number of redist regions is enough for all
vcpus. And there is already a test for that case in, the first step of
test_v3_new_redist_regions.

Add tests for checking that KVM returns the right error when trying to
set GICv2 CPU interfaces or GICv3 Redistributors partially above the
addressable IPA range. Also tighten the IPA range by replacing
KVM_CAP_ARM_VM_IPA_SIZE with the IPA range currently configured for the
guest (i.e., the default).
The check for the GICv3 redistributor created using the REDIST legacy
API is not sufficient as this new test only checks the check done using
vcpus already created when setting the base. The next commit will add
the missing test which verifies that the KVM check is done at first vcpu
run.

As a preparation for the next commits which will add some tests for
GICv2, make aarch64/vgic_init GIC version agnostic. Add a new generic
run_tests function(gic_dev_type) that starts all applicable tests using
GICv3 or GICv2. GICv2 tests are attempted if GICv3 is not available in
the system. There are currently no GICv2 tests, but the test passes now
in GICv2 systems.

The verifier tests added in commit c48e51c8b07a ("bpf: selftests: Add
selftests for module kfunc support") fail on s390, since the JIT does
not support calling kernel functions. This is most likely an issue for
all the other non-Intel arches, as well as on Intel with
!CONFIG_DEBUG_INFO_BTF or !CONFIG_BPF_JIT.
Trying to check for messages from all the possible add_kfunc_call()
failure cases in test_verifier looks pointless, so do a much simpler
thing instead: just like it's already done in do_prog_test_run(), skip
the tests that fail to load with ENOTSUPP.
