Excerpt:Ingo Molnár Ingo Molnár , currently employed by Red Hat , is a Hungarian Linux hacker . He is best-known for his contributions to the operating system in terms of security and performance . Some of his additions to the Linux include an O(1) and CFS scheduler in the 2.6.x kernel series, the in-kernel TUX HTTP / FTP server , as well as his work to enhance thread handling. He also wrote a kernel security feature called "Exec Shield ", which prevents stack-based buffer overflow exploits in the x86 architecture by disabling the execute permission for the stack.
