History
seccomp was first devised by Andrea Arcangeli in January 2005 for use in public grid computing and was originally intended as a means of safely running untrusted compute-bound programs.
It was merged into the Linux kernel mainline in kernel version 2.6.12, which was released on March 8, 2005.
