Jin Yao 3d8bba9535 perf xyarray: Fix wrong processing when closing evsel fd 
In current xyarray code, xyarray__max_x() returns max_y, and xyarray__max_y()
returns max_x.

It's confusing and for code logic it looks not correct.

Error happens when closing evsel fd. Let's see this scenario:

1. Allocate an fd (pseudo-code)

  perf_evsel__alloc_fd(struct perf_evsel *evsel, int ncpus, int nthreads)
  {
	evsel->fd = xyarray__new(ncpus, nthreads, sizeof(int));
  }

  xyarray__new(int xlen, int ylen, size_t entry_size)
  {
	size_t row_size = ylen * entry_size;
	struct xyarray *xy = zalloc(sizeof(*xy) + xlen * row_size);

	xy->entry_size = entry_size;
	xy->row_size   = row_size;
	xy->entries    = xlen * ylen;
	xy->max_x      = xlen;
	xy->max_y      = ylen;
	......
  }

So max_x is ncpus, max_y is nthreads and row_size = nthreads * 4.

2. Use perf syscall and get the fd

  int perf_evsel__open(struct perf_evsel *evsel, struct cpu_map *cpus,
		     struct thread_map *threads)
  {
	for (cpu = 0; cpu < cpus->nr; cpu++) {

		for (thread = 0; thread < nthreads; thread++) {
			int fd, group_fd;

			fd = sys_perf_event_open(&evsel->attr, pid, cpus->map[cpu],
						 group_fd, flags);

			FD(evsel, cpu, thread) = fd;
	}
  }

  static inline void *xyarray__entry(struct xyarray *xy, int x, int y)
  {
	return &xy->contents[x * xy->row_size + y * xy->entry_size];
  }

These codes don't have issues. The issue happens in the closing of fd.

3. Close fd.

  void perf_evsel__close_fd(struct perf_evsel *evsel)
  {
	int cpu, thread;

	for (cpu = 0; cpu < xyarray__max_x(evsel->fd); cpu++)
		for (thread = 0; thread < xyarray__max_y(evsel->fd); ++thread) {
			close(FD(evsel, cpu, thread));
			FD(evsel, cpu, thread) = -1;
		}
  }

  Since xyarray__max_x() returns max_y (nthreads) and xyarry__max_y()
  returns max_x (ncpus), so above code is actually to be:

        for (cpu = 0; cpu < nthreads; cpu++)
                for (thread = 0; thread < ncpus; ++thread) {
                        close(FD(evsel, cpu, thread));
                        FD(evsel, cpu, thread) = -1;
                }

  It's not correct!

This change is introduced by "475fb533fb7d" ("perf evsel: Fix buffer overflow
while freeing events")

This fix is to let xyarray__max_x() return max_x (ncpus) and
let xyarry__max_y() return max_y (nthreads)

Committer note:

This was also fixed by Ravi Bangoria, who provided the same patch,
noticing the problem with 'perf record':

<quote Ravi>
I see 'perf record -p <pid>' crashes with following log:
