Currently the pthread allocation for each array item is based on the size
of a pthread_t pointer and should be the size of the pthread_t structure,
so the allocation is under-allocating the correct size. Fix this by using
the size of each element in the pthreads array.
Static analysis cppcheck reported:
tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer
'threads' used instead of size of its data. [pointerSize]

William writes:
Second set of Counter fixes for 6.5
The I8254 Kconfig entry is repositioned to resolve a misplacement
causing the "Counter support" submenu items to disappear in menuconfig.
The tools/counter/Makefile clean recipe is adjusted to replace rmdir
with an equivalent set of rm to prevent failure if someone tries to
clean the counter directory without building it first.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix segfault in the powerpc specific arch_skip_callchain_idx
function. The patch doing the reference count init/exit that went
into 6.5 missed this function.
- Fix regression reading the arm64 PMU cpu slots in sysfs, a patch
removing some code duplication ended up duplicating the /sysfs prefix
for these files.
- Fix grouping of events related to topdown, addressing a regression on
the CSV output produced by 'perf stat' noticed on the downstream tool
toplev.
- Fix the uprobe_from_different_cu 'perf test' entry, it is failing
when gcc isn't available, so we need to check that and skip the test
if it is not installed.

The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19df
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.
To fix this, simply remove the unnecessary "all" dependency from the
emit_tests target. The dependency is still effectively honored, because
again, invocation is via "install", which also depends upon "all".
An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

syzkaller found zero division error [0] in div_s64_rem() called from
get_cycle_time_elapsed(), where sched->cycle_time is the divisor.
We have tests in parse_taprio_schedule() so that cycle_time will never
be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().
The problem is that the types of divisor are different; cycle_time is
s64, but the argument of div_s64_rem() is s32.
syzkaller fed this input and 0x100000000 is cast to s32 to be 0.
@TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}
We use s64 for cycle_time to cast it to ktime_t, so let's keep it and
set max for cycle_time.
While at it, we prevent overflow in setup_txtime() and add another
test in parse_taprio_schedule() to check if cycle_time overflows.
Also, we add a new tdc test case for this issue.

Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic
illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the
current VMX mode. KVM historically has neglected to reject bad CR0s from
userspace, i.e. would happily accept a completely bogus CR0 via
KVM_SET_SREGS{2}.
Punt VMX specific subtests to future work, as they would require quite a
bit more effort, and KVM gets coverage for CR0 checks in general through
other means, e.g. KVM-Unit-Tests.

Expand the binary stats test to verify that a stats fd can be dup()'d
and read, to (very) roughly simulate userspace passing around the file.
Adding the dup() test is primarily an intermediate step towards verifying
that userspace can read VM/vCPU stats before _and_ after userspace closes
its copy of the VM fd; the dup() test itself is only mildly interesting.

Move the stats fd cleanup code into stats_test() and drop the
superfluous vm_stats_test() and vcpu_stats_test() helpers in order to
decouple creation of the stats file from consuming/testing the file
(deduping code is a bonus). This will make it easier to test various
edge cases related to stats, e.g. that userspace can dup() a stats fd,
that userspace can have multiple stats files for a singleVM/vCPU, etc.

To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.

Prior to this change, events without a group would be sorted as if they
were from the location of the first event without a group. For example
instructions and cycles are without a group:
instructions,{imc_free_running/data_read/,imc_free_running/data_write/},cycles
parse events would create an eventual evlist like:
instructions,cycles,{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_1/data_read/,uncore_imc_free_running_0/data_write/,uncore_imc_free_running_1/data_write/}
This is done so that perf metric events, that must always be in a
group, will be adjacent and so can be forced into a group.
This change modifies the sorting so that only force grouped events,
like perf metrics, are sorted and all other events keep their position
with respect to groups in the evlist. The location of the force
grouped event is chosen to match the first force grouped event.
For architectures without force grouped events, ie anything not Intel
Icelake or newer, this should mean sorting and fixing doesn't modify
the event positions except when fixing the grouping for PMUs of things
like uncore events.

The evsel grouping fix iterates over evsels tracking the leader group
and the current position's group, updating the current position's leader
if an evsel is being forced into a group or groups changed. However,
groups changing isn't a sufficient condition as sorting may have
reordered events and the leader may no longer come first. For this
reason update all leaders whenever they disagree.
This change breaks certain Icelake+ metrics due to bugs in the
kernel. For example, tma_l3_bound with threshold enabled tries to
program the events:
{topdown-retiring,slots,CYCLE_ACTIVITY.STALLS_L2_MISS,topdown-fe-bound,EXE_ACTIVITY.BOUND_ON_STORES,EXE_ACTIVITY.1_PORTS_UTIL,topdown-be-bound,cpu/INT_MISC.RECOVERY_CYCLES,cmask=1,edge/,CYCLE_ACTIVITY.STALLS_L3_MISS,CPU_CLK_UNHALTED.THREAD,CYCLE_ACTIVITY.STALLS_MEM_ANY,EXE_ACTIVITY.2_PORTS_UTIL,CYCLE_ACTIVITY.STALLS_TOTAL,topdown-bad-spec}:W
fixing the perf metric event order gives:
{slots,topdown-retiring,topdown-fe-bound,topdown-be-bound,topdown-bad-spec,CYCLE_ACTIVITY.STALLS_L2_MISS,EXE_ACTIVITY.BOUND_ON_STORES,EXE_ACTIVITY.1_PORTS_UTIL,cpu/INT_MISC.RECOVERY_CYCLES,cmask=1,edge/,CYCLE_ACTIVITY.STALLS_L3_MISS,CPU_CLK_UNHALTED.THREAD,CYCLE_ACTIVITY.STALLS_MEM_ANY,EXE_ACTIVITY.2_PORTS_UTIL,CYCLE_ACTIVITY.STALLS_TOTAL}:W
Both of these return "<not counted>" for all events, whilst they work
with the group removed respecting that the perf metric events must still
be grouped. A vendor events update will need to add METRIC_NO_GROUP to
these metrics to workaround the kernel PMU driver issue.

Perf metric (topdown) events on Intel Icelake+ machines require a
group, however, they may be next to events that don't require a group.
Consider:
cycles,slots,topdown-fe-bound
The cycles event needn't be grouped but slots and topdown-fe-bound need
grouping.
Prior to this change, as slots and topdown-fe-bound need a group forcing
and all events share the same PMU, slots and topdown-fe-bound would be
forced into a group with cycles.
This is a bug on two fronts, cycles wasn't supposed to be grouped and
cycles can't be a group leader with a perf metric event.
This change adds recognition that cycles isn't force grouped and so it
shouldn't be force grouped with slots and topdown-fe-bound.

Add a mitigation for the speculative return address stack overflow
vulnerability found on AMD processors.
The mitigation works by ensuring all RET instructions speculate to
a controlled location, similar to how speculation is controlled in the
retpoline sequence. To accomplish this, the __x86_return_thunk forces
the CPU to mispredict every function return using a 'safe return'
sequence.
To ensure the safety of this mitigation, the kernel must ensure that the
safe return sequence is itself free from attacker interference. In Zen3
and Zen4, this is accomplished by creating a BTB alias between the
untraining function srso_untrain_ret_alias() and the safe return
function srso_safe_ret_alias() which results in evicting a potentially
poisoned BTB entry and using that safe one for all function returns.
In older Zen1 and Zen2, this is accomplished using a reinterpretation
technique similar to Retbleed one: srso_untrain_ret() and
srso_safe_ret().

When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.
not ok 373 3992 - Add ct action triggering DNAT tuple conflict
Could not match regex pattern. Verify command output:
cat: /proc/net/nf_conntrack: No such file or directory
It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.
Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

Another test which now exercies the path of the verifier where it will
explore call chains rooted at the async callback. Without the prior
fixes, this program loads successfully, which is incorrect.

git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Don't group events when computing metrics that require more than the
maximum number of simultaneously enabled events on AMD systems.
- Fix multi CU handling in 'perf probe', add a 'perf test' entry to
regress test it.
- Make the 'perf test task_exit' stop generating samples by using the
'dummy' event, all it is testing is if a PERF_RECORD_EXIT is
generated at the end of a perf session. This makes this perf test to
stop sometimes failing on some systems due to a full ring buffer.
- Avoid SEGV if PMU lookup fails for legacy cache terms.
- Fix libsubcmd SEGV/use-after-free when commands aren't excluded.
- Fix OpenCSD (ARM64's CoreSight hardware tracing) library path
resolution when specifying CSLIBS= in the make command line.
- Fix broken feature check for libtracefs due to external lib changes,
use the provided pkgconfig file instead future proof it.
- Sync drm, fcntl, kvm, mount, prctl, socket, vhost, asound, arm64's
cputype headers with the kernel sources, in some cases this made the
tools become aware of new kernel APIs such as ioctls and the
cachestat sysctl.
