It was merged into the Linux kernel mainline in kernel version 2.6.12, which was released on March 8, 2005.[1] seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit(), sigreturn(), read() and write() to already-open file descriptors. Should it attempt any other system calls, the kernel will terminate the process with SIGKILL or SIGSYS[2][3]. In this sense, it does not virtualize the system's resources but isolates the process from them entirely. + +## Dependencies + +## Building + +### Supported build tags + +## Contributing + +When
