Arnaldo Carvalho de Melo 6eaa8ee3e2 perf symbols: Fix signed overflow in sysfs__read_build_id() size check ...

sysfs__read_build_id() reads ELF note headers from sysfs files.  The
note's namesz and descsz fields are used to compute the skip size:

    int n = namesz + descsz;
    if (n > (int)sizeof(bf))

Both namesz and descsz are size_t from NOTE_ALIGN() of 32-bit note
header fields.  Their sum can exceed INT_MAX, overflowing the signed
int n to a negative value.  The check n > sizeof(bf) then evaluates
false (negative < positive in signed comparison), and read(fd, bf, n)
reinterprets the negative n as a huge size_t count — the kernel writes
up to MAX_RW_COUNT bytes into the 8192-byte stack buffer.

In practice the overflow is bounded by the sysfs file's actual size,
so a real sysfs notes file won't trigger it organically.  But crafted
input (e.g. via a mounted debugfs/sysfs image) could.

Fix by validating namesz and descsz individually against the buffer
size before summing, and change n to size_t to avoid the signed
overflow entirely.
