Subject [jira] [Created] (YARN-6721) container-executor should have -fstack-check
Date Mon, 19 Jun 2017 17:07:00 GMT
Allen Wittenauer created YARN-6721:
--------------------------------------

             Summary: container-executor should have -fstack-check
                 Key: YARN-6721
                 URL: https://issues.apache.org/jira/browse/YARN-6721
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
            Reporter: Allen Wittenauer


As per https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt and given that container-executor
is setuid, it should be compiled with stack checking if the compiler supports such features.
 (-fstack-check on gcc, -fsanitize=safe-stack on clang, -xcheck=stkovf on "Oracle Solaris
Studio", others as we find them, ...)
