Pull perf tools fixes from Namhyung Kim:
"Fixes for use-after-free that resulted in segfaults after merging the
bpf tree.
Also a couple of build and test fixes"
* tag 'perf-tools-fixes-for-v6.17-2025-09-05' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools:
perf symbol-elf: Add support for the block argument for libbfd
perf test: Checking BPF metadata collection fails on version string
perf tests: Fix "PE file support" test build
perf bpf-utils: Harden get_bpf_prog_info_linear
perf bpf-utils: Constify bpil_array_desc
perf bpf-event: Fix use-after-free in synthesis

Add the ability to dump BPF program instructions directly from veristat.
Previously, inspecting a program required separate bpftool invocations:
one to load and another to dump it, which meant running multiple
commands.
During active development, it's common for developers to use veristat
for testing verification. Integrating instruction dumping into veristat
reduces the need to switch tools and simplifies the workflow.
By making this information more readily accessible, this change aims
to streamline the BPF development cycle and improve usability for
developers.
This implementation leverages bpftool, by running it directly via popen
to avoid any code duplication and keep veristat simple.

This test makes sure we do send a FIN on close()
if the receive queue contains data that was consumed.

James Clark caught that the BUILD_NONDISTRO=1 build with libbfd was
broken due to an update to the read_build_id function adding a
blocking argument. Add support for this argument by first opening the
file blocking or non-blocking, then switching from bfd_openr to
bfd_fdopenr and passing the opened fd. bfd_fdopenr closes the fd on
error and when bfd_close are called.

commit edf2cadf01e8f ("perf test: add test for BPF metadata collection")
fails consistently on the version string check. The perf version
string on some of the constant integration test machines contains
characters with special meaning in grep's extended regular expression
matching algorithm. The output of perf version is:
# perf version
perf version 6.17.0-20250814.rc1.git20.24ea63ea3877.63.fc42.s390x+git
#
and the '+' character has special meaning in egrep command.
Also the use of egrep is deprecated.
Change the perf version string check to fixed character matching
and get rid of egrep's warning being deprecated. Use grep -F instead.
Output before:
# perf test -F 102
Checking BPF metadata collection
egrep: warning: egrep is obsolescent; using grep -E
Basic BPF metadata test [Failed invalid output]
102: BPF metadata collection test : FAILED!
#
Output after:
# perf test -F 102
Checking BPF metadata collection
Basic BPF metadata test [Success]
102: BPF metadata collection test : Ok
#
Fixes: edf2cadf01e8f ("perf test: add test for BPF metadata collection")

The "Parsing of PMU event table metrics with fake PMUs" will test
metrics on machines/models that may be missing a PMU, in such a case
the fake_pmu should be used to avoid errors.
Metrics that get the cpumask from a different PMU, such as
"tsc/cpu=cpu_atom/", also need to be resilient in this test.
The parse_events_state fake_pmu is set when missing PMUs should be
ignored.
So that it can be queried, pass it to the config term functions, as well
as to get_config_cpu, then ignore failures when fake_pmu is set.
Some minor code refactoring to cut down on the indent and remove some
redundant checks.

Remove unused 'elf' and 'path' parameters from parse_usdt_note function
signature. These parameters are not referenced within the function body
and only add unnecessary complexity.
The function only requires the note header, data buffer, offsets, and
output structure to perform USDT note parsing.
Update function declaration, definition, and the single call site in
collect_usdt_targets() to match the simplified signature.
This is a safe internal cleanup as parse_usdt_note is a static function.

Filtering pid_tgid is meanlingless when the current task is preempted by
an interrupt.
To address this, introduce 'bpf_in_interrupt()' helper function, which
allows BPF programs to determine whether they are executing in interrupt
context.
'get_preempt_count()':
* On x86, '*(int *) bpf_this_cpu_ptr(&__preempt_count)'.
* On arm64, 'bpf_get_current_task_btf()->thread_info.preempt.count'.
Then 'bpf_in_interrupt()' will be:
* If !PREEMPT_RT, 'get_preempt_count() & (NMI_MASK | HARDIRQ_MASK
| SOFTIRQ_MASK)'.
* If PREEMPT_RT, '(get_preempt_count() & (NMI_MASK | HARDIRQ_MASK))
| (bpf_get_current_task_btf()->softirq_disable_cnt & SOFTIRQ_MASK)'.
As for other archs, it can be added support by updating
'get_preempt_count()'.

The blamed commit introduced the concept of split attribute
counting, and later allocating an array to hold them, however
TypeArrayNest wasn't updated to use the new counting variable.
Abbreviated example from tools/net/ynl/generated/nl80211-user.c:
nl80211_if_combination_attributes_parse(...):
unsigned int n_limits = 0;
[...]
ynl_attr_for_each(attr, nlh, yarg->ys->family->hdr_len)
if (type == NL80211_IFACE_COMB_LIMITS)
ynl_attr_for_each_nested(attr2, attr)
dst->_count.limits++;
if (n_limits) {
dst->_count.limits = n_limits;
/* allocate and parse attributes */
}
In the above example n_limits is guaranteed to always be 0,
hence the conditional is unsatisfiable and is optimized out.
This patch changes the attribute counting to use n_limits++ in the
attribute counting loop in the above example.

Provide scx_bpf_cpu_curr() as a way for scx schedulers to check the curr
task of a remote rq without assuming its lock is held.
Many scx schedulers make use of scx_bpf_cpu_rq() to check a remote curr
(e.g. to see if it should be preempted). This is problematic because
scx_bpf_cpu_rq() provides access to all fields of struct rq, most of
which aren't safe to use without holding the associated rq lock.

Most fields in scx_bpf_cpu_rq() assume that its rq_lock is held.
Furthermore they become meaningless without rq lock, too.
Make a safer version of scx_bpf_cpu_rq() that only returns a rq
if we hold rq lock of that rq.
Also mark the new scx_bpf_locked_rq() as returning NULL as
scx_bpf_cpu_rq() should've been too.
