tools lib traceevent: Fix buffer overflow in arg_eval Fix buffer overflow observed when running perf test. The overflow is when trying to evaluate "1ULL << (64 - 1)" which is resulting in -9223372036854775808 which overflows the 20 character buffer. If is possible this bug has been reported before but I still don't see any fix checked in: See: https://www.spinics.net/lists/linux-perf-users/msg07714.html Reported-by: Michael Sartain <[email protected]> Reported-by: Mathias Krause <[email protected]> Signed-off-by: Tony Jones <[email protected]> Acked-by: Steven Rostedt (VMware) <[email protected]> Cc: Frederic Weisbecker <[email protected]> Fixes: f7d82350e597 ("tools/events: Add files to create libtraceevent.a") Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
