security_getenforce(3)    SELinux API documentation   security_getenforce(3)

NAME         top

       security_getenforce,    security_setenforce,   security_deny_unknown,
       security_get_checkreqprot- get or set the enforcing state of SELinux

SYNOPSIS         top

       #include <selinux/selinux.h>

       int security_getenforce(void);

       int security_setenforce(int value);

       int security_deny_unknown(void);

       int security_get_checkreqprot(void);

DESCRIPTION         top

       security_getenforce() returns 0 if SELinux is running in permissive
       mode, 1 if it is running in enforcing mode, and -1 on error.

       security_setenforce() sets SELinux to enforcing mode if the value 1
       is passed in, and sets it to permissive mode if 0 is passed in.  On
       success 0 is returned, on error -1 is returned.

       security_deny_unknown() returns 0 if SELinux treats policy queries on
       undefined object classes or permissions as being allowed, 1 if such
       queries are denied, and -1 on error.

       security_get_checkreqprot() can be used to determine whether SELinux
       is configured to check the protection requested by the application or
       the actual protection that will be applied by the kernel (including
       the effects of READ_IMPLIES_EXEC) on mmap and mprotect calls.  It
       returns 0 if SELinux checks the actual protection, 1 if it checks the
       requested protection, and -1 on error.
