# proc\_pid\_seccomp(5)

secure computing mode

## NAME

/proc/pid/seccomp - secure computing mode

## DESCRIPTION

- */proc/*pid*/seccomp* (Linux 2.6.12 to Linux 2.6.22)

  This file can be used to read and change the process's secure computing (seccomp) mode setting. It contains the value 0 if the process is not in seccomp mode, and 1 if the process is in strict seccomp mode (see [**seccomp**(2)](/seccomp/2.md)). Writing 1 to this file places the process irreversibly in strict seccomp mode. (Further attempts to write to the file fail with the **EPERM** error.)

-

  In Linux 2.6.23, this file went away, to be replaced by the [**prctl**(2)](/prctl/2.md) **PR\_GET\_SECCOMP** and **PR\_SET\_SECCOMP** operations (and later by [**seccomp**(2)](/seccomp/2.md) and the *Seccomp* field in */proc/*pid*/status*).
