.TH proc_pid_seccomp 5 2023-08-15 "Linux man-pages 6.7"
.SH NAME
/proc/pid/seccomp \- secure computing mode
.SH DESCRIPTION
.TP
.IR /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
.BR 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
.B EPERM
error.)
.IP
In Linux 2.6.23,
this file went away, to be replaced by the
.BR prctl (2)
.B PR_GET_SECCOMP
and
.B PR_SET_SECCOMP
operations (and later by
.BR seccomp (2)
and the
.I Seccomp
field in
.IR /proc/ pid /status ).
