[PATCHES 0/5 v2] More perf.data header validation

[Arnaldo Carvalho de Melo]

Hi,

	This is picking up from what was reported in the previous
series, pre-existing lack of perf.data file validation, processing files
and buffers in header.c in a similar fashion.

	There is more to process in the trace data, but that is a
different can of worms that needs to be dealt with in a similar,
upcoming patch series,

	This is probably 7.2 material, but if feeling this can still
sneak into 7.1, feel free to do it :-)

	Now lets see what Sashiko discovers while I still don't have it
running locally right after Claude, before submitting it publicly, which
will soon happen :-)

v2: Addressed sashiko comments, adding a patch to the series.

  perf header: Validate string length before allocating in do_read_string()
  perf header: Sanity check HEADER_EVENT_DESC
