Tony Jones be8e9e9ebf tools lib traceevent: Fix buffer overflow in arg_eval ... [ Upstream commit 7c5b019e3a638a5a290b0ec020f6ca83d2ec2aaa ] 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 <mikesart@fastmail.com> Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Tony Jones <tonyj@suse.de> Acked-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Fixes: f7d82350e5 ("tools/events: Add files to create libtraceevent.a") Link: http://lkml.kernel.org/r/20190228015532.8941-1-tonyj@suse.de Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2019-04-27 09:33:49 +02:00
