proc_pid_seccomp(5)                      File Formats Manual                     proc_pid_seccomp(5)

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)).  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) PR_GET_SECCOMP
              and PR_SET_SECCOMP operations (and later  by  seccomp(2)  and  the  Seccomp  field  in
              /proc/pid/status).
