eb7261f14e perf test: Add free() calls for scandir() returned dirent entries
ASan reported a memory leak for items of the entlist returned from scandir().

In fact, scandir() returns a malloc'd array of malloc'd dirents.

This patch adds the missing (z)frees.

53d31a3ffd SMB3.1.1: Add support for negotiating signing algorithm
Support for faster packet signing (using GMAC instead of CMAC) can
now be negotiated to some newer servers, including Windows.
See MS-SMB2 section 2.2.3.17.

This patch adds support for sending the new negotiate context
with the first of three supported signing algorithms (AES-CMAC)
and decoding the response.  A followon patch will add support
for sending the other two (including AES-GMAC, which is fastest)
and changing the signing algorithm used based on what was
negotiated.

c47a5599ed perf tools: Fix pattern matching for same substring in different PMU type
Some different PMU types may have the same substring. For example, on
Icelake server we have PMU types "uncore_imc" and
"uncore_imc_free_running". Both PMU types have the substring
"uncore_imc".  But the parser wrongly thinks they are the same PMU type.

We enable an imc event,
perf stat -e uncore_imc/event=0xe3/ -a -- sleep 1

Perf actually expands the event to:

  uncore_imc_0/event=0xe3/
  uncore_imc_1/event=0xe3/
  uncore_imc_2/event=0xe3/
  uncore_imc_3/event=0xe3/
  uncore_imc_4/event=0xe3/
  uncore_imc_5/event=0xe3/
  uncore_imc_6/event=0xe3/
  uncore_imc_7/event=0xe3/
  uncore_imc_free_running_0/event=0xe3/
  uncore_imc_free_running_1/event=0xe3/
  uncore_imc_free_running_3/event=0xe3/
  uncore_imc_free_running_4/event=0xe3/

That's because the "uncore_imc_free_running" matches the
pattern "uncore_imc*".

Now we check that the last characters of PMU name is '_<digit>'.

For example, for pattern "uncore_imc*", "uncore_imc_0" is parsed ok, but
"uncore_imc_free_running_0" fails.

b91e5492f9 perf record: Add a dummy event on hybrid systems to collect metadata records
Some symbols may not be resolved if a user only monitors one type of
PMU.

  $ sudo perf record -e cpu_atom/branch-instructions/ ./big_small_workload
  $ sudo perf report –stdio
  # Overhead  Command    Shared Object      Symbol
  # ........  .........  .................  .....................
  #
     28.02%  perf-exec  [unknown]          [.] 0x0000000000401cf6
     11.32%  perf-exec  [unknown]          [.] 0x0000000000401d04
     10.90%  perf-exec  [unknown]          [.] 0x0000000000401d11
     10.61%  perf-exec  [unknown]          [.] 0x0000000000401cfc

To parse symbols the metadata records, e.g., PERF_RECORD_COMM, which are
generated by the kernel, are required.

To decide whether to generate the metadata records, the kernel relies on
the event_filter_match() to filter the unrelated events.

On a hybrid system, event_filter_match() further checks the CPU mask of
the current enabled PMU. If an event is collected on the CPU which
doesn't have an enabled PMU, it's treated as an unrelated event.

The "big_small_workload" is created in a big core, but runs on a small
core. The metadata records are filtered, because the user only monitors
the PMU of the small core. The big core PMU is not enabled.

For a hybrid system, a dummy event is required to generate the complete
side-band events.

5f148e7c6a perf stat: Add Topdown metrics L2 events as default events
The Topdown Microarchitecture Analysis (TMA) Method is a structured
analysis methodology to identify critical performance bottlenecks in
out-of-order processors.

The Topdown metrics L1 event was added as default in 42641d6f4d
("perf stat: Add Topdown metrics events as default events")

From the Sapphire Rapids server and later platforms, the same dedicated
"metrics" register is extended to support both L1 and L2 events.

Add both L1 and L2 Topdown metrics events as default to enrich the
default measuring information if the new measurement register is
available.

On legacy systems there is no change to avoid extra multiplexing.

The topdown_level indicates the max metrics level for the top-down
statistics. Set it to 2 to display all L1 and L2 Topdown metrics events.

With the patch:

  $ perf stat sleep 1

fba7c86601 libperf: Move 'leader' from tools/perf to perf_evsel::leader
Move evsel::leader to perf_evsel::leader, so we can move the group
interface to libperf.

Also add several evsel helpers to ease up the transition:

  struct evsel *evsel__leader(struct evsel *evsel);
  - get leader evsel

  bool evsel__has_leader(struct evsel *evsel, struct evsel *leader);
  - true if evsel has leader as leader

  bool evsel__is_leader(struct evsel *evsel);
  - true if evsel is itw own leader

  void evsel__set_leader(struct evsel *evsel, struct evsel *leader);
  - set leader for evsel

Committer notes:

Fix this when building with 'make BUILD_BPF_SKEL=1'

  tools/perf/util/bpf_counter.c

  -       if (evsel->leader->core.nr_members > 1) {
  +       if (evsel->core.leader->nr_members > 1) {

38fe0e0156 libperf: Move 'idx' from tools/perf to perf_evsel::idx
Move evsel::idx to perf_evsel::idx, so we can move the group interface
to libperf.

Committer notes:

Fixup evsel->idx usage in tools/perf/util/bpf_counter_cgroup.c, that
appeared in my tree in my local tree.

Also fixed up these:

$ find tools/perf/ -name "*.[ch]" | xargs grep 'evsel->idx'
tools/perf/ui/gtk/annotate.c:                      evsel->idx + i);
tools/perf/ui/gtk/annotate.c:                   evsel->idx);
$

That running 'make -C tools/perf build-test' caught.

227c4d507c f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
 such as allowing compression for mmap files, replacing the immutable bit with
 internal bit to prohibits data writes explicitly, and adding a mount option,
 "compress_cache", to improve random reads. And, we added "readonly" feature to
 compact the partition w/ compression enabled, which will be useful for Android
 RO partitions.
 
 Enhancement:
  - support compression for mmap file
  - use an f2fs flag instead of IMMUTABLE bit for compression
  - support RO feature w/ extent_cache
  - fully support swapfile with file pinning
  - improve atgc tunability
  - add nocompress extensions to unselect files for compression
 
 Bug fix:
  - fix false alaram on iget failure during GC
  - fix race condition on global pointers when there are multiple f2fs instances
  - add MODULE_SOFTDEP for initramfs
 
 As usual, we've also cleaned up some places for better code readability.

47ce8527fb MIPS: vdso: Invalid GIC access through VDSO
Accessing raw timers (currently only CLOCK_MONOTONIC_RAW) through VDSO
doesn't return the correct time when using the GIC as clock source.
The address of the GIC mapped page is in this case not calculated
correctly. The GIC mapped page is calculated from the VDSO data by
subtracting PAGE_SIZE:

  void *get_gic(const struct vdso_data *data) {
    return (void __iomem *)data - PAGE_SIZE;
  }

However, the data pointer is not page aligned for raw clock sources.
This is because the VDSO data for raw clock sources (CS_RAW = 1) is
stored after the VDSO data for coarse clock sources (CS_HRES_COARSE = 0).
Therefore, only the VDSO data for CS_HRES_COARSE is page aligned:

  +--------------------+
  |                    |
  | vd[CS_RAW]         | ---+
  | vd[CS_HRES_COARSE] |    |
  +--------------------+    | -PAGE_SIZE
  |                    |    |
  |  GIC mapped page   | <--+
  |                    |
  +--------------------+

When __arch_get_hw_counter() is called with &vd[CS_RAW], get_gic returns
the wrong address (somewhere inside the GIC mapped page). The GIC counter

1fee9db9b4 irqchip/mips: Fix RCU violation when using irqdomain lookup on interrupt entry
Since d4a45c68dc ("irqdomain: Protect the linear revmap with RCU"),
any irqdomain lookup requires the RCU read lock to be held.

This assumes that the architecture code will be structured such as
irq_enter() will be called *before* the interrupt is looked up
in the irq domain. However, this isn't the case for MIPS, and a number
of drivers are structured to do it the other way around when handling
an interrupt in their root irqchip (secondary irqchips are OK by
construction).

This results in a RCU splat on a lockdep-enabled kernel when the kernel
takes an interrupt from idle, as reported by Guenter Roeck.

Note that this could have fired previously if any driver had used
tree-based irqdomain, which always had the RCU requirement.

To solve this, provide a MIPS-specific helper (do_domain_IRQ())
as the pendent of do_IRQ() that will do thing in the right order
(and maybe save some cycles in the process).

Ideally, MIPS would be moved over to using handle_domain_irq(),
but that's much more ambitious.

6a942f5780 s390: preempt: Fix preempt_count initialization
S390's init_idle_preempt_count(p, cpu) doesn't actually let us initialize the
preempt_count of the requested CPU's idle task: it unconditionally writes
to the current CPU's. This clearly conflicts with idle_threads_init(),
which intends to initialize *all* the idle tasks, including their
preempt_count (or their CPU's, if the arch uses a per-CPU preempt_count).

Unfortunately, it seems the way s390 does things doesn't let us initialize
every possible CPU's preempt_count early on, as the pages where this
resides are only allocated when a CPU is brought up and are freed when it
is brought down.

Let the arch-specific code set a CPU's preempt_count when its lowcore is
allocated, and turn init_idle_preempt_count() into an empty stub.

4ee471fe5a s390/linkage: increase asm symbols alignment to 16
Both clang and gcc (for -march=z13 and later) align functions to 16
bytes at -O2 to benefit branch prediction.

Make asm symbols alignment consistent with that.

This also benefits potential ftrace code patching, which is currently
able to patch 8 aligned bytes at once.

With defconfig this currently increases .text size by 4104 bytes.
