NAME

       security_load_policy - load a new SELinux policy

SYNOPSIS

       #include <selinux/selinux.h>

       int security_load_policy(void *data, size_t len);

       int selinux_mkload_policy(int preservebools);

       int selinux_init_load_policy(int *enforce);

DESCRIPTION

       security_load_policy loads a new policy, returns 0 for success and -1 for error.

       selinux_mkload_policy  makes  a	policy	image  and loads it. This function provides a higher level interface for loading policy than secu-
       rity_load_policy, internally determining the right policy version, locating and opening the policy file, mapping it into memory, manipulat-
       ing it as needed for current boolean settings and/or local definitions, and then calling security_load_policy to load it.  preservebools is
       a boolean flag indicating whether current policy boolean values should be preserved into the new policy (if 1) or reset to the saved policy
       settings  (if 0). The former case is the default for policy reloads, while the latter case is an option for policy reloads but is primarily
       used for the initial policy load.  selinux_init_load_policy performs the initial policy load. This function determines the desired  enforc-
       ing  mode, sets the enforce argument accordingly for the caller to use, sets the SELinux kernel enforcing status to match it, and loads the
       policy. It also internally handles the initial selinuxfs mount required to perform these actions.

       It should also be noted that after the initial policy load, the SELinux kernel code cannot anymore be disabled and the selinuxfs cannot	be
       unmounted  using a call to security_disable(3).	Therefore, after the initial policy load, the only operational changes are those permitted
       by setenforce(3) (i.e. eventually setting the framework in permissive mode rather than in enforcing one).

RETURN VALUE

       returns zero on success or -1 on error.
