Where is the execstack in CentOS 7?

Question

I want to mark the binary as not requiring executable stack on CentOS 7.2 with execstack, but there is no such utility and yum does not find package execstack. Why is this the case? Is this utility is not used now?

[root@localhost bin]# execstack
-bash: execstack: command not found

Answer 1

execstack is provided by the package prelink in centos-7. Here,

http://mirror.centos.org/centos-7/7/os/x86_64/Packages/prelink-0.5.0-9.el7.x86_64.rpm

~]$ rpm -qlp http://mirror.centos.org/centos-7/7/os/x86_64/Packages/prelink-0.5.0-9.el7.x86_64.rpm | grep exec
/usr/bin/execstack
/usr/share/man/man8/execstack.8.gz


# install using YUM
~]$ yum install prelink
