Adrian Hunter b5dc2f2578 perf intel-pt: Fix segfault in intel_pt_print_info() with uClibc ... commit 5a3d47071f upstream. uClibc segfaulted because NULL was passed as the format to fprintf(). That happened because one of the format strings was missing and intel_pt_print_info() didn't check that before calling fprintf(). Add the missing format string, and check format is not NULL before calling fprintf(). Fixes: 11fa7cb86b ("perf tools: Pass Intel PT information for decoding MTC and CYC") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20221012082259.22394-2-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2022-10-26 13:25:54 +02:00
