security_disable(3)     SELinux API documentation     security_disable(3)

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 using
       security_setenforce(3).

RETURN VALUE         top

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