Merge tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tool updates from Arnaldo Carvalho de Melo:
"New features:

- Enable use of BPF counters with 'perf stat --for-each-cgroup',
using per-CPU 'cgroup-switch' events with an attached BPF program
that does aggregation per-cgroup in the kernel instead of using
per-cgroup perf events.

- Add Topdown metrics L2 events as default events in 'perf stat' for
systems having those events.

Hardware tracing:

- Add a config for max loops without consuming a packet in the Intel
PT packet decoder, set via 'perf config intel-pt.max-loops=N'

Hardware enablement:

- Disable misleading NMI watchdog message in 'perf stat' on hybrid
systems such as Intel Alder Lake.

- Add a dummy event on hybrid systems to collect metadata records.

- Add 24x7 nest metric events for the Power10 platform.

Fixes:

- Fix event parsing for PMUs starting with the same prefix.

- Fix the 'perf trace' 'trace' alias installation dir.

- Fix buffer size to report iregs in perf script python scripts,
supporting the extended registers in PowerPC.

- Fix overflow in elf_sec__is_text().

- Fix 's' on source line when disasm is empty in the annotation TUI,
accessible via 'perf annotate', 'perf report' and 'perf top'.

- Plug leaks in scandir() returned dirent entries in 'perf test' when
sorting the shell tests.

- Fix --task and --stat with pipe input in 'perf report'.

- Fix 'perf probe' use of debuginfo files by build id.

- If a DSO has both dynsym and symtab ELF sections, read from both
when loading the symbol table, fixing a problem processing Fedora
32 glibc DSOs.

Libraries:

- Add grouping of events to libperf, from code in tools/perf,
allowing libperf users to use that mode.

Misc:

- Filter plt stubs from the 'perf probe --functions' output.

- Update UAPI header copies for asound, DRM, mman-common.h and the
ones affected by the quotactl_fd syscall"

perf top: Fix overflow in elf_sec__is_text()

ASan reports a heap-buffer-overflow in elf_sec__is_text when using perf-top.

The bug is caused by the fact that secstrs is built from runtime_ss, while
shdr is built from syms_ss if shdr.sh_type != SHT_NOBITS. Therefore, they
point to two different ELF files.

This patch renames secstrs to secstrs_run and adds secstrs_sym, so that
the correct secstrs is chosen depending on shdr.sh_type.

perf symbol-elf: Decode dynsym even if symtab exists

In Fedora34, libc-2.33.so has both .dynsym and .symtab sections and
most of (not all) symbols moved to .dynsym. In this case, perf only
decode the symbols in .symtab, and perf probe can not list up the
