security_load_policy(3) SELinux API documentation security_load_policy(3)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
security_load_policy(), internally determining the right policy version, locating and opening the policy file, mapping it into memory,
manipulating it as needed for current boolean settings and/or local definitions, and then calling security_load_policy to load it. pre-
servebools 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 enforcing 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 security_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.
