Now that the BUSY bit mess is gone (for x2APIC), verify that the *guest*
can read back the ICR value that it wrote. Due to the divergent
behavior between AMD and Intel with respect to the backing storage of the
ICR in the vAPIC page, emulating a seemingly simple MSR write is quite
complex.

Actually test x2APIC ICR reserved bits instead of deliberately skipping
them. The behavior that is observed when IPI virtualization is enabled is
the architecturally correct behavior, KVM is the one who was wrong, i.e.
KVM was missing reserved bit checks.

Don't test the ICR BUSY bit when x2APIC is enabled as AMD and Intel have
different behavior (AMD #GPs, Intel ignores), and the fact that the CPU
performs the reserved bit checks when IPI virtualization is enabled makes
it impossible for KVM to precisely emulate one or the other.

Add helpers to allow and expect #GP on x2APIC MSRs, and opportunistically
have the existing helper spit out a more useful error message if an
unexpected exception occurs.

Now that selftests support printf() in the guest, report unexpected
exceptions via the regular assertion framework. Exceptions were special
cased purely to provide a better error message. Convert only x86 for now,
as it's low-hanging fruit (already formats the assertion in the guest),
and converting x86 will allow adding asserts in x86 library code without
needing to update multiple tests.
Once all other architectures are converted, this will allow moving the
reporting to common code, which will in turn allow adding asserts in
common library code, and will also allow removing UCALL_UNHANDLED.

Open code a version of vcpu_run() in the guest_printf test in anticipation
of adding UCALL_ABORT handling to _vcpu_run(). The guest_printf test
intentionally generates asserts to verify the output, and thus needs to
bypass common assert handling.
Open code a helper in the guest_printf test, as it's not expected that any
other test would want to skip _only_ the UCALL_ABORT handling.

Someone reported on GitHub that the YNL NIPA test is failing
when run locally. The test builds the tools, and it hits:
netdev.c:82:9: warning: ignoring return value of ‘scanf’ declared with attribute ‘warn_unused_result’ [-Wunused-result]
82 | scanf("%d", &ifindex);
I can't repro this on my setups but error seems clear enough.

When dropping a local kptr, any kptr stashed into it is supposed to be
freed through bpf_obj_free_fields->__bpf_obj_drop_impl recursively. Add a
test to make sure it happens.
The test first stashes a referenced kptr to "struct task" into a local
kptr and gets the reference count of the task. Then, it drops the local
kptr and reads the reference count of the task again. Since
bpf_obj_free_fields and __bpf_obj_drop_impl will go through the local kptr
recursively during bpf_obj_drop, the dtor of the stashed task kptr should
eventually be called. The second reference count should be one less than
the first one.

With a file, to write data an offset needs to be known. Typically data
follows the event attributes in a file.
However, if processing a pipe the number of event attributes may not be
known.
It is convenient in that case to write the attributes after the data.
Expand perf_session__do_write_header() to allow this when the data
offset and size are known.
This approach may be useful for more than just taking a pipe file to
write into a data file, `perf inject --itrace` will reserve and
additional 8kb for attributes, which would be unnecessary if the
attributes were written after the data.

Buggy perf.data files can have the attributes and data
overlapping.
For example, when processing pipe data the attributes aren't known and
so file offset header calculations can consider them not present.
Later this can cause the attributes to overwrite the data. This can be
seen in:
$ perf record -o - true > a.data
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.059 MB - ]
$ perf inject -i a.data -o b.data
$ perf report --stats -i b.data
0x68 [0]: failed to process type: 510379 [Invalid argument]
Error:
failed to process sample
$
This change makes reading the corrupt file fail:
$ perf report --stats -i b.data
Perf file header corrupt: Attributes and data overlap
incompatible file format (rerun with -v to learn more)
$
Which is more informative.

v0.1 HW_ID packets have a new field that describes which sink each CPU
writes to. Use the sink ID to link trace ID maps to each other so that
mappings are shared wherever the sink is shared.
Also update the error message to show that overlapping IDs aren't an
error in per-thread mode, just not supported. In the future we can
use the CPU ID from the AUX records, or watch for changing sink IDs on
HW_ID packets to use the correct decoders.

Now that each queue has a unique set of trace ID mappings, use this
list to create the decoders. In unformatted mode just add a single
mapping so only one decoder is made.
Previously each queue would have a decoder created for each traced CPU
on the system but this won't work anymore because CPUs can have
overlapping trace IDs.
This also means that the CORESIGHT_TRACE_ID_UNUSED_FLAG isn't needed
any more. If mappings aren't added then decoders aren't created, rather
than needing a flag to suppress creation.

The global list won't work for per-sink trace ID allocations, so put a
list in each queue where the IDs will be unique to that queue.
To keep the same behavior as before, for version 0 of the HW_ID packets,
copy all the HW_ID mappings into all queues.
This change doesn't effect the decoders, only trace ID lookups on the
Perf side. The decoders are still created with global mappings which
will be fixed in a later commit.

We do an ugly copying of options in bpf_object__open_skeleton() just to
be able to set object name from skeleton's recorded name (while still
allowing user to override it through opts->object_name).
This is not just ugly, but it also is broken due to memcpy() that
doesn't take into account potential skel_opts' and user-provided opts'
sizes differences due to backward and forward compatibility. This leads
to copying over extra bytes and then failing to validate options
properly. It could, technically, lead also to SIGSEGV, if we are unlucky.
So just get rid of that memory copy completely and instead pass
default object name into bpf_object_open() directly, simplifying all
this significantly. The rule now is that obj_name should be non-NULL for
bpf_object_open() when called with in-memory buffer, so validate that
explicitly as well.
We adopt bpf_object__open_mem() to this as well and generate default
name (based on buffer memory address and size) outside of bpf_object_open().

Make cs_etm__setup_queue() setup a queue even if it's empty, and
pre-allocate queues based on the max CPU that was recorded. In per-CPU
mode aux queues are indexed based on CPU ID even if all CPUs aren't
recorded, sparse queue arrays aren't used.
This will allow HW_IDs to be saved even if no aux data was received in
that queue without having to call cs_etm__setup_queue() from two
different places.

Both of these passes gather information about how to create the
decoders. AUX records determine formatted/unformatted, and the HW_IDs
determine the traceID/metadata mappings.
Therefore it makes sense to cache the information and wait until both
passes are over until creating the decoders, rather than creating them
at the first HW_ID found.
This will allow a simplification of the creation process where
cs_etm_queue->traceid_list will exclusively used to create the decoders,
rather than the current two methods depending on whether the trace is
formatted or not.
Previously the sample CPU from the AUX record was used to initialize
the decoder CPU, but actually sample CPU == AUX queue index in per-CPU
mode, so saving the sample CPU isn't required.
Similarly formatted/unformatted was used upfront to create the decoders,
but now it's cached until later.

feature detection from working"
Ian pointed out that the libcap feature test is also used by bpftool, so
we can't remove it just because perf stopped using it, revert the
removal of the feature test.
Since both perf and libcap uses the fast path feature detection
(tools/build/feature/test-all.c), probably the best thing is to keep
libcap-devel when building perf even it not being used there.
This reverts commit 47b3b6435e4bfb61ae8ffc63a11bd3c310f69acf.

Charlie Jenkins <charlie@rivosinc.com> says:
There have been a couple of reports that using the hint address to
restrict the address returned by mmap hint address has caused issues in

mmap is necessary to avoid breakages.

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.

This test extends "delete and re-add" to validate the previous commit:
when the endpoint linked to the initial subflow (ID 0) is re-added
multiple times, it was no longer being used, because the internal linked

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.
This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

RM_ADDR for the right ID, and the removal of the subflow. That's what is
now being verified in the "delete and re-add" test.

Largely inspired from hid_bpf.c for the fixture setup.
Create a couple of tests for hidraw:
- create a uhid device and check if the fixture is working properly
- inject one uhid event and read it through hidraw
These tests are not that useful for now, but will be once we start adding
the ioctl and BPFs to revoke the hidraw node.

5cb57a1aff75 ("KVM: arm64: Zero ID_AA64PFR0_EL1.GIC when no GICv3 is

register fixup where KVM clobbers the GIC field in absence of GICv3.
While the field technically has FTR_LOWER_SAFE behavior, fix the issue
by setting it to an exact value of 0, matching the effect of the 'late'

detection from working
I noticed that the fast path feature detection was failing:
$ cat /tmp/build/perf-tools-next/feature/test-all.make.output
/usr/bin/ld: cannot find -lcap: No such file or directory
collect2: error: ld returned 1 exit status
$
The patch removing the dependency (Fixes tag below) didn't remove the
detection of libcap, and as the fast path feature detection (test-all.c)
had -lcap in its Makefile link list of libraries to link, it was failing
when libcap-devel is not available, fix it by removing those leftover
files.

The new cgroup filter can take either of '==' or '!=' operator and a
pathname for the target cgroup.
$ perf record -a --all-cgroups -e cycles --filter 'cgroup == /abc/def' -- sleep 1
Users should have --all-cgroups option in the command line to enable
cgroup filtering. Technically it doesn't need to have the option as
it can get the current task's cgroup info directly from BPF. But I want
to follow the convention for the other sample info.

The fields in the hist_entry are filled on-demand which means they only
have meaningful values when relevant sort keys are used.
So if neither of 'dso' nor 'sym' sort keys are used, the map/symbols in
the hist entry can be garbage. So it shouldn't access it
unconditionally.
I got a segfault, when I wanted to see cgroup profiles.

As you can see the entry->ms.map was NULL even if he->ms.map has a

'sym' sort key here as it implies 'dso' behavior (so maps are the same).
