NAME        top

       security_disable - disable the SELinux kernel code at runtime

SYNOPSIS        top

#include <selinux/selinux.h>int security_disable(void);

DESCRIPTION        top

security_disable() disables the SELinux kernel code, unregisters       selinuxfs from/proc/filesystems, and then unmounts/sys/fs/selinux.       This function is only supported on Linux 6.3 and earlier, and can       only be called at runtime and prior to the initial policy load.       After the initial policy load, the SELinux kernel code cannot be       disabled, but only placed in "permissive" mode by usingsecurity_setenforce(3).

RETURN VALUE        top

security_disable() returns zero on success or -1 on error.
