Ingo Molnár

From Wikipedia, the free encyclopedia

Ingo Molnár, currently employed by Red Hat, is a Hungarian Linux kernel hacker. He is most well-known for his contributions to the operating system in terms of security and performance. Some of his additions to the Linux kernel 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.^[1] 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. One of his recent projects is the realtime preemption patch, which aims to bring hard-realtime scheduling latencies (50–60 microseconds worst-case execution time) to the Linux kernel.

Most recently, he has been working on the Completely Fair Scheduler (CFS), an O(log n) scheduler that is included as of the 2.6.23 Linux kernel.^[2]
