perf stat: Close cork_fd when create_perf_stat_counter() failed

[ Upstream commit e880a70f8046df0dd9089fa60dcb866a2cc69194 ]

When create_perf_stat_counter() failed, it doesn't close workload.cork_fd
open in evlist__prepare_workload(). This could make too many open file
error while __run_perf_stat() repeats.

Introduce evlist__cancel_workload to close workload.cork_fd and
wait workload.child_pid until exit to clear child process
when create_perf_stat_counter() is failed.

Metrics were added by a callback but commit a4b8cfcabb1d90ec ("perf
stat: Delay metric parsing") postponed this to allow optimizations based
on the CPU configuration.

In doing so it stopped errors in metric parsing from causing 'perf stat'
termination.

This change adds the termination for bad metric names back in.

The issue was the use of testing a cpumap with NULL rather than using
empty, as a map containing the dummy value isn't NULL and the -1
results in an empty aggr map being allocated which legitimately
overflows when any member is accessed.

Merge tag 'perf-tools-for-v6.5-1-2023-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next

Pull perf tools updates from Namhyung Kim:
"Internal cleanup:

- Refactor PMU data management to handle hybrid systems in a generic
way.

Do more work in the lexer so that legacy event types parse more
easily. A side-effect of this is that if a PMU is specified,
scanning sysfs is avoided improving start-up time.

- Fix hybrid metrics, for example, the TopdownL1 works for both
performance and efficiency cores on Intel machines. To support
this, sort and regroup events after parsing.

- Add reference count checking for the 'thread' data structure.

- Lots of fixes for memory leaks in various places thanks to the ASAN
and Ian's refcount checker.

- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.

- Introduce shared_mutex for annotate data to reduce memory
footprint.

- Make filesystem access library functions more thread safe.

Test:

- Organize cpu_map tests into a single suite.

- Add metric value validation test to check if the values are within
correct value ranges.

- Add perf stat stdio output test to check if event and metric names
match.

- Add perf data converter JSON output test.

- Fix a lot of issues reported by shellcheck(1). This is a
preparation to enable shellcheck by default.

- Make the large x86 new instructions test optional at build time
using EXTRA_TESTS=1.

- Add a test for libpfm4 events.

perf script:

- Add 'dsoff' outpuf field to display offset from the DSO.

$ perf script -F comm,pid,event,ip,dsoff
ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5)

ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms])

- Adjust width for large PID/TID values.

perf report:

- Robustify reading addr2line output for srcline by checking sentinel
output before the actual data and by using timeout of 1 second.

- Allow config terms (like 'name=ABC') with breakpoint events.

$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1

perf annotate:

- Handle x86 instruction suffix like 'l' in 'movl' generally.

- Parse instruction operands properly even with a whitespace. This is
needed for llvm-objdump output.

- Support RISC-V binutils lookup using the triplet prefixes.

- Add '<' and '>' key to navigate to prev/next symbols in TUI.

- Fix instruction association and parsing for LoongArch.

perf stat:

- Add --per-cache aggregation option, optionally specify a cache
level like `--per-cache=L2`.

$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\
taskset -c 0-15,64-79,128-143,192-207\

- Allow --cputype option to have any PMU name (not just hybrid).

- Fix output value not to added when it runs multiple times with -r
option.

- Show metricgroup description from JSON file called
metricgroups.json.

- Allow 'pfm' argument to list only libpfm4 events and check each
event is supported before showing it.

JSON vendor events:

- Avoid event grouping using "NO_GROUP_EVENTS" constraints. The
topdown events are correctly grouped even if no group exists.

- Add "Default" metric group to print it in the default output. And
use "DefaultMetricgroupName" to indicate the real metric group
name.

- Add AmpereOne core PMU events.

Misc:

- Define man page date correctly.

- Track exception level properly on ARM CoreSight ETM.

- Allow anonymous struct, union or enum when retrieving type names
from DWARF.

- Fix incorrect filename when calling `perf inject --jit`.

- Handle PLT size correctly on LoongArch"
