| .TH proc_pid_seccomp 5 (date) "Linux man-pages (unreleased)" |
| .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 ). |
| .SH SEE ALSO |
